Low and Middle-Income Countries (LMICs) tend to be more affected, with chronic low back pain (CLBP) being among the leading presenting complaints at specialist consultation. The exact burden of this disease is sparingly known in our setting. Objective: To evaluate the burden of chronic low back pain at the Yaounde Central Hospital. Methods: This was a descriptive cross-sectional study for a period of 3 months, from March 2022 to May 2022. After obtaining ethical clearance and research authorisations, data was collected using structured questionnaires from patients with chronic low back pain presenting at the Yaounde Central Hospital during the aforementioned time frame. This data was then tabulated with the Statistical Package for Social Sciences (SPSS 23.0), and disability was assessed using the modified Roland Morris Disability Questionnaire and the Oswestry Disability Index. Data analysis was done using the International Business Machines Statistical Package for Social Sciences (IBM-SPSS) VERSION 23.0. Results: 115 cases of CLBP were included. The mean age was 52.62 years, and the sex ratio was 0.3. The average monthly income was less than 50,000 frs CFA, in 37.4% of cases. In 57.9%, patients had a job that involved physical labour. The patients had a secondary level of education in 40.9%, and alcohol consumption was observed in 36%. The average number of days of a work stoppage due to LBP was 12.75 days (±12SD), and the median duration of CLBP was 7.15 (7.5SD) years. The median pain intensity was 7 (±2SD), with leg pain and sensory neuropathy observed in 67.8% and 63.5% respectively. Lumbar X-ray was done in 45.2% and revealed lumbar osteoarthrosis in 62.4%. Hypertension as a comorbidity was observed in 26.1%. Medical treatment was used at least once in 98.3% of cases. The average cost of management per month was assessed, and the median was 52,000 FCFA (±20,876 SD). Using the Oswestry Disability Questionnaire, 46 patients, that is 40% of the study population, were classified as severely disabled with a median ODI score of 40%. The factors which were independently associated with disability were level of education, alcohol consumption, treatment modality, pain intensity, body mass index (BMI), psychological wellbeing and number of sick leave days. Conclusion: Chronic low back pain is common in our setting. There is a female predominance with the mean age of the study population situated in the 5th decade. Low-income earners and patients with a job involving physical labour were the most affected. Medical treatment was the main therapeutic modality, with the average cost of management per month being above the average monthly income of the greater majority of the patients. Several factors influenced disability, some of which were independently associated with it, such as level of education, alcohol consumption and treatment modality.展开更多

They represent 23% of admissions to the Yaounde emergency center (CURY), which is a center exclusively dedicated, since 2014, to emergency care in Yaounde. In the management of trauma brain injuries at CURY, several are operated on. However, to date, no evaluation of these operated patients has yet been made. Goals: The objective of this study was to highlight the prognostic factors in patients operated for TBI at CURY. Methodology: We conducted a descriptive study whose data collection was done retrospectively over 2 years (01 January 2021 to 31 December 2022) at CURY. Data was collected from the registers of operative reports. Results: We enrolled 105 medical reports of patients who were victims of TBI operated on. The male gender predominated with a sex ratio of 3/1. The average age of the patients was 37.5 ± 18.83 years. Public road accidents were the leading cause of TBI in 75.2% of cases. The means of transport of the victims were mostly non-medical 97.1%. 45.7% of patients were admitted in less than 6 hours following injury. The initial clinical evaluation found 45.8% of patients with a Glasgow Coma Score (GCS) between [14, 15], and 13.2% of patients had a GCS 8. The indications for surgery were extradural hematoma (30%), followed by acute subdural hematoma (24%). The major complication was postoperative infection (25%). The mortality rate of the series was 7.9%. Poor prognostic factors were the depth of the coma on admission, advanced age and postoperative complications. Conclusion: The results of this study suggest that most patients operated on for TBI at CURY had a favorable outcome. The poor prognostic factors were the depth of the coma on admission, advanced age, postoperative complications and comorbidities.展开更多

An attempt has also been made to estimate aquifer transmissivity from resistivity data. The transmissivity of the uncon?ned aquifer was computed by determining the Dar-Zarrouk parameters (longitudinal unit conductance and transverse unit resistance) and were compared with the actual field transmissivity. The results showed a direct relation between aquifer transmissivity and transverse resistance. The relationship established has therefore, been generalized in the study area in order to evaluate hydraulic conductivity and transmissivity at all the points where geoelectrical measurements have been carried out. This generalization allows one to derive maps of the product Kσ and transmissivity in the study area based on geoelectrical measurements. These maps are important in future modelling processes oriented towards better exploitation of the aquifers.展开更多

Infertility is of male origin in 40% of cases. Our objective was to evaluate the epidemiological and clinical aspects of male infertility in our setting. Methods: This was a cross-sectional and descriptive study, with retrospective data collection from the files of patients received for male infertility, over 5 years and 6 months (from January 1<sup>st</sup>, 2016 to April 30<sup>th</sup>, 2021) at the Urology Department of the Yaounde Central Hospital. Phone calls were made to patients with incomplete records for completion following a verbal consent. Data reported on data collection forms were entered into a data entry form designed on CSPro software version 7.2. The database was later exported for descriptive statistics using the IBM SPSS software version 23. Qualitative variables were summarized in frequencies and percentages while quantitative variables were summarized in means with their standard deviations for normally distributed data, or medians and interquartile ranges otherwise. Results: Out of 110 patients whose records were analyzed, the median age was 37.0 years, with an interquartile range of 8.3, with 55.5% in the age group 30 to 39 years. Of these 95 (86.4%) were married, 58 (52.7%) were from the West region, 76 (69.1%) were employed. Past history was dominated by mumps 40 (36.4%), varicocele surgery 25 (22.7%), alcoholism 87 (79.1%) and smoking 15 (13.6%). A disorder of spermatogenesis was found in all our patients: 37 (33.6%) azoospermia, 27 (24.6%) asthenospermia and 26 (23.7%) oligospermia patients. Paraclinical evidence of chlamydia and gonococcal infections were found respectively in 38 (34.5%) and 14 (12.7%) patients, varicocele and testicular dystrophy respectively in 95 (86.4%) and 38 (34.5%) patients. Infertility was primary in 67 (60.9%) patients. Conclusion: Most patients with infertility were in their thirties, had risky social habits and comorbidities. An early start of health promotion activities, comorbidities prevention and early detection of spermogram abnormalities would make it possible to reduce the frequency of male infertility.展开更多

It is?one of the most complications in admitted patients, particularly inlow-income settings. The epidemiological data on VTE are still lacking. Methods: We carried out a cross-sectional study in three hospitals in Yaoundé. We retrospectively reviewed records of patients admitted for VTE from January 2013 to December 2017. We collected data on socio-demography, clinical presentation, venous Doppler/pulmonary CT scan, and outcome. Results: We included 93 patients (43 males) with VTE. Their mean age was 53.3 ± 16.6 years. There were 46 (49.5%) cases of Deep Vein Thrombosis (DVT), 36 (38.7%) cases of Pulmonary Embolism (PE), and 11 (11.8%) cases of PE associated with DVT. The main risk factors were obesity/overweight (58.1%), immobility (43%), HIV infection (22.6%), prior admission (22.6%), and long trip (19.4%). The most frequent clinical presentation for PE was dyspnea (100%), tachypnea (87.2%), and chest pain (70.2%). For DVT, limb pain (93%), calf stiffness (86%), limb volume > 3 cm (82.4%) were the most common presentation. There were 9 (9.7%) in-hospital deaths. Mean hospital stay was 20.7 ± 30.8 days. Conclusion:VTE is underdiagnosed in our setting. Obesity and immobility were the main risk factors. Dyspnea and tachypnea were the main clinical presentation for PE whereas limb pain and calf stiffness were the main symptoms for DVT. In-hospital mortality is still high.展开更多

About a third of women affected are aged less than 40 years. Chemotherapy (CT) could alter ovarian function and thereby compromise future fertility in these women. We therefore described the fertility of women following CT for BC in women treated at the Yaounde General Hospital (YGH). Methods: It was a retrospective, descriptive, cross-sectional study conducted over 8 months, from January to August 2017. We used the files of patients managed for BC from January 2011 to December 2015 in the medical oncology unit of the YGH. Results: We included 265 patients for the study following at least one year of CT. The mean age at the onset of CT was 35.9 ± 6.9 years. Most of the patients had fewer than 2 deliveries (68.3%). Intraductal carcinoma was the most frequent histological lesion (90.6%) and most often diagnosed in advanced stages (73.5%). As per CT, the FAC protocol was the most used (44.5%). The menstrual cycles of the patients were more regular prior to the onset of chemotherapy (89.4% vs. 58.9%), while the mean period of resumption of menstrual activity following cessation of chemotherapy was 6.3 ± 2.0 months. Chemotherapy-related amenorrhoea was observed in 29.1% of patients after 12 months of treatment. More than half of these women (51.3%) complained of a drop in libido and 6.4% achieved pregnancy within 13 months following cessation of chemotherapy. Conclusion: Following chemotherapy for BC, menstrual cycle disorders are more frequent and this can affect the patients’ reproductive potential. Fertility consultations should be integrated into the management plan of such patients.展开更多

We assessed the psychomotor development of children born before 37 weeks of gestation.?Methods:?This was a descriptive cross-sectional study conducted in the Pediatric Department of the Yaounde Gynaeco-Obstetric and Pediatric Hospital from January to May 2018. We used the Denver II scale to assess the psychomotor development of children born premature aged 9 months to 6 years. Children born between January 2012 and April 2017 at a gestational age strictly below 37 weeks of gestation were included. Using logistic regression, we searched for perinatal factors associated with abnormalities of psychomotor developmental.?Results:?We included 50 children in our study, 60% of whom were boys, giving a sex ratio of 1.5. The mean age was 25 ± 19.5 months. The mean gestational age was 33 ± 2.2 weeks and the mean birth weight was 2178.68 ± 748.01 g. The average Developmental Quotient of the population was 108. Six children (12%) had a global developmental delay (DQ ?70), 22% of the children had a language delay. Convulsion was associated with motor delay (OR = 16;P = 0.03), and pregnancy monitoring a protective factor for language delay (P = 0.02).?Conclusion:?Improving perinatal care remains a preoccupying issue. The assessment of psychomotor development should be done until early childhood to enable early diagnosis of learning disabilities.展开更多

Particularly scarce are surveys of data spanning travel, return, and follow-up of the same cohort in traveling agencies and parks. This study examines behavior and illness among travelers moving from Yaounde to other urban and rural areas of Cameroon and beyond. Patterns of behavior connected to a type of travel and illness are characterized in this study so as to identify risks factors and provide background data for pre-travel advice in our traveling agencies. Assessing the susceptibility that imported cases could pose to the national response to infectious diseases depends both on public health, health services and infrastructures. The six agencies assessed: Nvan, Mokolo, Tongolo, Biyem Assi, Mimbowman and Etoudi reveal that the sanitary infrastructures for faecal and urinary disposal are not sufficient and more so, some agencies do not keep enough cleanliness, let alone provide adequate hand washing material as prescribed by national and international concerns to combat the global health challenges. This could be an impediment to travellers going out or inside of the city, and could be a preponderant mechanism for the spread of infectious disease as presented by the infectious diseases isolated and identified in the health districts around the travelling agencies.展开更多

We sought to measure patient satisfaction following major gynaecological surgeries in 2 University Teaching Hospitals in Yaounde, Cameroon. Methods: This study was a cross-sectional, prospective study over 9 months (October 1st, 2018, to June 30th, 2019) at the Yaounde Gynaeco-Obstetric and Paediatric Hospital (YGOPH) and the Yaounde Central Hospital (YCH). By administering a modified Surgical Satisfaction Questionnaire (SSQ-8) via phone call 6 months after surgery, we appreciated and scored key aspects linked to patient satisfaction and obtained information on post-operative complications. Data were analysed using Microsoft Excel 18 and SPSS 21 setting significance at p Results: We recruited 72 patients aged 24 to 68 years. Our participants had a mean satisfaction score of 26 ± 7.854 (59.7% satisfied and 40.3% dissatisfied). All aspects tested on the SSQ-8 questionnaire influenced patient satisfaction. Patients who said they were satisfied with pain control after surgery (OR = 0.207 CI = 0.070 - 0.609, p = 0,003), and with surgical results in the SSQ-8 questionnaire (OR = 0.053, CI = 0.011 - 0.254, p < 0.001) achieved statistically significant post-operative satisfaction. Contrarily, patients who were dissatisfied with surgery results (OR = 132.000, CI = 15.256 - 114.131, p < 0.001) and those who developed complications (OR = 7.922, CI = 2.241 - 28.004, p < 0.001) were significantly dissatisfied with surgery. Additionally, 47.2% declared a poor post-operative current health status versus 52.8% who claimed a good post-operative current health status. Following multivariate analysis, satisfaction with the results of surgery (OR = 0.071, CI = 0.008 - 0.657, p = 0.020) and the occurrence of complications (OR = 7.284, CI = 1.146 - 46.273, p = 0.035) were the main determinants of patient satisfaction. Patient current health status evolved similarly to patient satisfaction and especially by satisfaction with time taken to resume work (OR = 0.039, CI = 0.004 - 0.398, p = 0.006) and pre-operative exercise routine (OR = 0.038, CI = 0.002 - 0.678, p-value = 0026). Conclusion: Patient satisfaction with elective gynaecological surgery is low and determined by post-operative experiences and the occurrence of complications. Also, patients self-reported current health status tends to evolve similarly to satisfaction following surgery.展开更多

To this effect, they play an important role in the survival of city dwellers as well as the embellishment of the city. In 2006, Nsam market was created in the Nsam quarter Yaounde with little financial concentration. Over the years, this market has outlived its usefulness to the extent that its present functioning is an eyesore. Amongst the causes to this are the facts that, the market was created following no predefined standards, the city has grown and the market can no longer handle the dependent population. From field observations, this study aimed at proposing a complete renovated plan for the Nsam market in Yaounde, Cameroon. The study relied on secondary and primary sources of data collected and treated following some pre-set standards. These data enabled an analysis of the diagnosis of the situation prevailing there where it led to the conclusion of a complete renovation of the market. This renovated market is expected to better the working conditions of traders, create more jobs which will boost revenue collection and embellishment of the city amongst others.展开更多

However, Open adrenalectomy is indicated in large adrenal tumors, malignant tumors and large phaeochromocytomas. We report surgical outcomes of 18 cases of functional adrenal tumors from 2007 to 2022. Methods: We conducted a retrospective cross-sectional and descriptive study in three tertiary hospitals in Yaounde, Cameroon. We reviewed files of patients who underwent adrenalectomy over a period of 15 years from July 2007 to July 2022. Clinical and diagnostic components of adrenal tumors, indications and surgical outcomes were analyzed. Results: A total of 18 patients were included in our study. The average age of patients was 38.33 years, with a female-to-male sex ratio of 2:1. Weight gain (72.2%) was the most represented clinical sign. The secretory nature of tumor and malignancy represented 55.5% and 33.3% of the operative indications and all 18 (100%) of the patients had open adrenalectomy. Vascular injury was the most common intraoperative complication with 5.63%, while acute adrenal insufficiency (16.7%) was the most common post-operative complication. The average tumor size was 6.22 cm and the mean duration of hospitalization was 11.61 days. Adenoma 7 (38.9%) and adrenocortical carcinoma 5 (27.8%) were the frequent histological types. One patient died two months post-surgery from anemia-related complications. Conclusion: The success of adrenal surgery is linked to multidisciplinary patient care and the experience of the surgeon. Conventional surgery still has indications with satisfactory short- and medium-term results in our context.展开更多

Study results show that pH is ranged between 5.1≤ pH ≤ 5.8 and then, induces acidic waters. Groundwater samples are generally characterized by low conductivity values, of which 100% are within the range (55 ≤ EC ≤ 1500 μS/cm). The mean values of the major cations (Ca2+, Mg2+, Na+, K+) and anions (SO42– , Cl–, HCO3– ) are all within the World Health Organization (WHO) standards. Two of the springs sampled have nitrate (NO3– ) contamination. Even though contamination and acidic waters exist in some of the springs, the majority of the springs are excellent for agricultural and domestic purposes. Assessment of the groundwater for agricultural irrigation revealed two main categories. These are low salinity-low sodicity (C1-S1) and medium salinity-low sodicity (C2-S1), using the US Salinity Laboratory (USSL) classification scheme. As much as all of the samples plotted in the “excellent to good” and “good to permissible” categories on the Wilcox diagram. The groundwater in the study area may therefore be regarded as good for irrigation activities. The major identifiable geochemical processes responsible for the evolution of the various ions are mineral weathering, chemical reactions and anthropogenic activities.展开更多

The public lighting in the capital city Yaounde is an example of solar energy promotion. The purpose of this paper is among other things aiming at assessing the solar energy resources of central Africa and making sure it can be used optimally at least for public lighting. Based on the knowledge from data collected and field experience for three years, the authors will assess the implementation of the technology and show how the use of solar energy can solve some problems in the city of Yaounde even when the area is grid connected. This paper will also identify actions for improved access to sustainable, friendly, affordable solar energy services to users, as well as a significant improvement of energy infrastructure and energy efficiency in the city. The authors will also address issues on identified obstacles for the promotion of solar energy in order to help the cities in sub Saharan countries to develop a vision aiming at developing good solar energy policy and better contribute to fight against poverty and climate change.展开更多

Objective: The objectives of this study were to elucidate the current epidemiology and describe the clinical, diagnostic and therapeutic features of ICMET in Yaounde. Method and findings: A descriptive cross-sectional study was done in the neurosurgery departments of the General and Central Hospitals of Yaounde during the period from January 2016 to December 2022. We included all medical booklets of patients admitted for a tumoral intracranial expansive process with our target population being patients with histological evidence of ICMET, and did a retrospective inclusion of data using a pre-established technical form aimed at collecting sociodemographic data, clinical data, paraclinical data, and the treatment procedures. Analysis was done using the SPSS statistical software. A total of 614 cases of intracranial tumors were included among whom 35 presented histological evidence of ICMET. This gives a frequency of 5.7%. The sex ratio was 0.94, the mean age was 55.68 +/- 14.4 years, extremes 28 and 86 years and the age range 50 - 59 was affected in 28.57% of cases. The clinical presentation included signs of raised intracranial pressure (headache, blurred vision, vomiting) in 26 cases (74.3%), motor deficit 48.6%, seizures 17.1%. The mode of onset was metachronous in 71.4% and synchronous in 28.6%. The imaging techniques were cerebral CT scan in 82.9%, cerebral MRI in 40%, TAP scan in 22.9%. The metastatic lesions were supratentorial in 94.3% and single in 62.9%. The primary cancers found were breast cancer (31.4%), lung cancer (25.7%), prostate cancer (17.1%), thyroid cancer (5.7%), colon cancer (2.9%), and melanoma (2.9%). The therapeutic modalities were total resection (68.6%), radiotherapy (37.1%). Conclusion: Intracranial metastases are relatively frequent. There is a female sex predominance and the age group 50 - 59 years is the most affected. Brain metastases mostly occur in patients with a history of known primary tumor. The clinical signs mainly include signs of raised intracranial pressure, motor deficit, seizures and mental confusion. Cerebral CT Scan is the main imaging technique used. Most of the lesions are single and supratentorially located. The primary cancers most represented include breast cancer, lung cancer and prostate cancer. Surgery is the main treatment procedure. The adjuvant treatment (radiotherapy, chemotherapy) was limited.展开更多

In developed countries, this practice is common and sees the indications constantly reviewed;In sub-Saharan Africa, this surgical technique is popularized. The external pathways are morbid and not very functional. In our daily practice at the Yaounde General Hospital (YGH), this technique is still in its infancy. Gradually it’s entering our habits and sees its indications increases. Through this study, we are reporting readily available data from our experience. <strong>Objectives:</strong> The objective was to study the practice of endoscopic endonasal surgery in our setting. <strong>Patients and Method:</strong> This was a cross-sectional, descriptive, retrospective study. The site of study was the ear-nose and throat service of Yaounde General Hospital. The study was conducted from January 2013 to December 2020, for an 8 years basis. The sampling was consecutive. We included in this study all patients operated on for a nasal sinus disease by the endoscopic endonasal modality. We excluded patients with incomplete files, as well as those who had a complementary transfacial approach during the same operation. The data were collected on prepared questionnaire. Data analysis is done with ssps 23.0 software. <strong>Results:</strong> We recruited 30 cases, out of a total of 330 interventions carried out in our department. The prevalence of this surgery in our activity was 9%. Male and female had equal ratio of 50%. The most represented age group was 30 - 40 years (33.3%). All the patients had a facial sinus CT scan, we did not note any anatomical variant as risk. Two patients of our sample size had a history of sinus surgery, treated externally. Chronic maxillary sinusitis was the surgical indication in 36.7%, followed by Killian antro-choanal polyps in 13.3%, nasosinus polyposis in 13.3% and all performed under general anesthesia. The most performed procedure was unilateral mean meatotomy with 43.33% followed by bilateral mean meatotomy with 20%, ethmoidectomy 13.3%, bimeatotomy 10%. The admission lasted for 2 days. 100% of patients had a previous nasal tamponade at the end of the intervention. The tamponade was removed on the second postoperative day in 100% of patients. 16.7% of patients presented with complications of low abundance postoperative bleeding. All patients noted clinical improvement over the initial symptoms postoperatively. <strong>Conclusion:</strong> Endoscopic endonasal surgery is experiencing slow but certain progress in our daily practice. The operated patients are young, chronic maxillary sinusitis is the main indication, the most performed procedure is the unilateral mean meatotomy. The operation goes uneventful with satisfactory prognosis. A study with a larger sample is necessary in order to refine our results. The practice remains limited by the technical platform, which needs to be strengthened, in order to optimize the practice.展开更多
文摘Background: Chronic low back pain is a leading cause of morbidity and disability globally. Low and Middle-Income Countries (LMICs) tend to be more affected, with chronic low back pain (CLBP) being among the leading presenting complaints at specialist consultation. The exact burden of this disease is sparingly known in our setting. Objective: To evaluate the burden of chronic low back pain at the Yaounde Central Hospital. Methods: This was a descriptive cross-sectional study for a period of 3 months, from March 2022 to May 2022. After obtaining ethical clearance and research authorisations, data was collected using structured questionnaires from patients with chronic low back pain presenting at the Yaounde Central Hospital during the aforementioned time frame. This data was then tabulated with the Statistical Package for Social Sciences (SPSS 23.0), and disability was assessed using the modified Roland Morris Disability Questionnaire and the Oswestry Disability Index. Data analysis was done using the International Business Machines Statistical Package for Social Sciences (IBM-SPSS) VERSION 23.0. Results: 115 cases of CLBP were included. The mean age was 52.62 years, and the sex ratio was 0.3. The average monthly income was less than 50,000 frs CFA, in 37.4% of cases. In 57.9%, patients had a job that involved physical labour. The patients had a secondary level of education in 40.9%, and alcohol consumption was observed in 36%. The average number of days of a work stoppage due to LBP was 12.75 days (±12SD), and the median duration of CLBP was 7.15 (7.5SD) years. The median pain intensity was 7 (±2SD), with leg pain and sensory neuropathy observed in 67.8% and 63.5% respectively. Lumbar X-ray was done in 45.2% and revealed lumbar osteoarthrosis in 62.4%. Hypertension as a comorbidity was observed in 26.1%. Medical treatment was used at least once in 98.3% of cases. The average cost of management per month was assessed, and the median was 52,000 FCFA (±20,876 SD). Using the Oswestry Disability Questionnaire, 46 patients, that is 40% of the study population, were classified as severely disabled with a median ODI score of 40%. The factors which were independently associated with disability were level of education, alcohol consumption, treatment modality, pain intensity, body mass index (BMI), psychological wellbeing and number of sick leave days. Conclusion: Chronic low back pain is common in our setting. There is a female predominance with the mean age of the study population situated in the 5th decade. Low-income earners and patients with a job involving physical labour were the most affected. Medical treatment was the main therapeutic modality, with the average cost of management per month being above the average monthly income of the greater majority of the patients. Several factors influenced disability, some of which were independently associated with it, such as level of education, alcohol consumption and treatment modality.
文摘Introduction: Head injuries constitute a public health problem in Cameroon and everywhere else in the world. They represent 23% of admissions to the Yaounde emergency center (CURY), which is a center exclusively dedicated, since 2014, to emergency care in Yaounde. In the management of trauma brain injuries at CURY, several are operated on. However, to date, no evaluation of these operated patients has yet been made. Goals: The objective of this study was to highlight the prognostic factors in patients operated for TBI at CURY. Methodology: We conducted a descriptive study whose data collection was done retrospectively over 2 years (01 January 2021 to 31 December 2022) at CURY. Data was collected from the registers of operative reports. Results: We enrolled 105 medical reports of patients who were victims of TBI operated on. The male gender predominated with a sex ratio of 3/1. The average age of the patients was 37.5 ± 18.83 years. Public road accidents were the leading cause of TBI in 75.2% of cases. The means of transport of the victims were mostly non-medical 97.1%. 45.7% of patients were admitted in less than 6 hours following injury. The initial clinical evaluation found 45.8% of patients with a Glasgow Coma Score (GCS) between [14, 15], and 13.2% of patients had a GCS 8. The indications for surgery were extradural hematoma (30%), followed by acute subdural hematoma (24%). The major complication was postoperative infection (25%). The mortality rate of the series was 7.9%. Poor prognostic factors were the depth of the coma on admission, advanced age and postoperative complications. Conclusion: The results of this study suggest that most patients operated on for TBI at CURY had a favorable outcome. The poor prognostic factors were the depth of the coma on admission, advanced age, postoperative complications and comorbidities.
文摘Detailed local geological and hydrogeophysical investigations were carried out for the aquifer in Yaoundé, Cameroon to delineate the architecture of different subsurface geological horizons using lithologs and generated vertical electrical sounding (VES) data. An attempt has also been made to estimate aquifer transmissivity from resistivity data. The transmissivity of the uncon?ned aquifer was computed by determining the Dar-Zarrouk parameters (longitudinal unit conductance and transverse unit resistance) and were compared with the actual field transmissivity. The results showed a direct relation between aquifer transmissivity and transverse resistance. The relationship established has therefore, been generalized in the study area in order to evaluate hydraulic conductivity and transmissivity at all the points where geoelectrical measurements have been carried out. This generalization allows one to derive maps of the product Kσ and transmissivity in the study area based on geoelectrical measurements. These maps are important in future modelling processes oriented towards better exploitation of the aquifers.
文摘Introduction: About 10 to 15% of couples in the world and 20 to 30% in Cameroon consult for infertility problems. Infertility is of male origin in 40% of cases. Our objective was to evaluate the epidemiological and clinical aspects of male infertility in our setting. Methods: This was a cross-sectional and descriptive study, with retrospective data collection from the files of patients received for male infertility, over 5 years and 6 months (from January 1<sup>st</sup>, 2016 to April 30<sup>th</sup>, 2021) at the Urology Department of the Yaounde Central Hospital. Phone calls were made to patients with incomplete records for completion following a verbal consent. Data reported on data collection forms were entered into a data entry form designed on CSPro software version 7.2. The database was later exported for descriptive statistics using the IBM SPSS software version 23. Qualitative variables were summarized in frequencies and percentages while quantitative variables were summarized in means with their standard deviations for normally distributed data, or medians and interquartile ranges otherwise. Results: Out of 110 patients whose records were analyzed, the median age was 37.0 years, with an interquartile range of 8.3, with 55.5% in the age group 30 to 39 years. Of these 95 (86.4%) were married, 58 (52.7%) were from the West region, 76 (69.1%) were employed. Past history was dominated by mumps 40 (36.4%), varicocele surgery 25 (22.7%), alcoholism 87 (79.1%) and smoking 15 (13.6%). A disorder of spermatogenesis was found in all our patients: 37 (33.6%) azoospermia, 27 (24.6%) asthenospermia and 26 (23.7%) oligospermia patients. Paraclinical evidence of chlamydia and gonococcal infections were found respectively in 38 (34.5%) and 14 (12.7%) patients, varicocele and testicular dystrophy respectively in 95 (86.4%) and 38 (34.5%) patients. Infertility was primary in 67 (60.9%) patients. Conclusion: Most patients with infertility were in their thirties, had risky social habits and comorbidities. An early start of health promotion activities, comorbidities prevention and early detection of spermogram abnormalities would make it possible to reduce the frequency of male infertility.
文摘The Yaounde Group(YG),representing the southern edge of the North Equatorial PanAfrican Belt,consists of quartzites,schists,micaschists,amphibolites,gneisses and migmatites.Tectonism has formed a landscape characterized by the development of linear and folded valleys and ridges,fault scarps,V-shaped valleys,incised rivers and knickpoints.These landforms constitute important markers of the regional tectonic activity,which have been computed from spatial sources such as SRTM,DEM,hydrographical networks and geomorphic indices such as AF,T,Smf,Vf,Bs,Hi,U,SI and Li.The results highlighted a mature relief consisting of asymmetric basins generated by tilting and uplift phenomena.The relative index of active tectonics(RIAT)has been estimated from an average of eight geomorphic indices evaluated on 24 subbasins,in the study area.Four classes have been defined:class 1(1.38),very high active(1.0≤RIAT<1.5);class 2(1.50-1.88),high active(1.5≤RIAT<2.0);and class 3(2.00-2.13)moderate active(2.0≤RIAT<2.5).These three classes,respectively covering 10.20%(458 km2),80.10%(3595 km2)and 9.69%(435 km2)of the study area,have shown a highly active tectonic zone,and imply the existence of a neotectonic event in the YG.This tectonic unit(YG)was also affected by the dextral NW-SE strike-slip faulting,which cross-cut the Sanaga Shear Zone(SSZ)at Ebebda and the foliation oriented NW-SE.The tilting and uplift of rocks related to Moho ascending are responsible for crustal thinning in the Cameroon basement,more important to the Adamawa Plateau from the Cretaceous age and the reactivation of existing tectonic accidents.The presence of hills,fault scarps,reverse faults,knickpoints,V and U shaped valleys and rounded mountains testify to the interaction between tectonic uplift,lithology,climate,weathering and erosion.
文摘The Proterozoic metasedimentary rocks of the Yaounde Group on the northern edge of the Congo Shield in Central Africa were investigated to understand their provenance and depositional environment.Petrography,geochemistry,and field evidence helped to subdivide the metasediments into paragneiss,mica schist,chlorite schist,and quartzite which were derived from greywacke,shale,quartz arenite,litharenite protoliths.They are immature with some mature samples,moderately weathered and reworked Neo-and Post-Archean metasediments.Rare earth element signatures(Chondrite Eu/Eu^(*)≤1),enrichment of light rare earth elements over the heavy ones,and the La/Sc ratio(>0.7)are compatible with those of the intermediate and felsic sources from the upper continental crust.These metasediments were deposited in the continental arc setting and have evolved during Proterozoic times according to the Wilson cycle to form the West Gondwana including NE Brazil.
文摘Background: Venous thromboembolic disease (VTE) is one of the main causes of cardiovascular death and a public health problem worldwide. It is?one of the most complications in admitted patients, particularly inlow-income settings. The epidemiological data on VTE are still lacking. Methods: We carried out a cross-sectional study in three hospitals in Yaoundé. We retrospectively reviewed records of patients admitted for VTE from January 2013 to December 2017. We collected data on socio-demography, clinical presentation, venous Doppler/pulmonary CT scan, and outcome. Results: We included 93 patients (43 males) with VTE. Their mean age was 53.3 ± 16.6 years. There were 46 (49.5%) cases of Deep Vein Thrombosis (DVT), 36 (38.7%) cases of Pulmonary Embolism (PE), and 11 (11.8%) cases of PE associated with DVT. The main risk factors were obesity/overweight (58.1%), immobility (43%), HIV infection (22.6%), prior admission (22.6%), and long trip (19.4%). The most frequent clinical presentation for PE was dyspnea (100%), tachypnea (87.2%), and chest pain (70.2%). For DVT, limb pain (93%), calf stiffness (86%), limb volume > 3 cm (82.4%) were the most common presentation. There were 9 (9.7%) in-hospital deaths. Mean hospital stay was 20.7 ± 30.8 days. Conclusion:VTE is underdiagnosed in our setting. Obesity and immobility were the main risk factors. Dyspnea and tachypnea were the main clinical presentation for PE whereas limb pain and calf stiffness were the main symptoms for DVT. In-hospital mortality is still high.
文摘Context: In Cameroon, breast cancer (BC) is usually diagnosed late in the disease course. About a third of women affected are aged less than 40 years. Chemotherapy (CT) could alter ovarian function and thereby compromise future fertility in these women. We therefore described the fertility of women following CT for BC in women treated at the Yaounde General Hospital (YGH). Methods: It was a retrospective, descriptive, cross-sectional study conducted over 8 months, from January to August 2017. We used the files of patients managed for BC from January 2011 to December 2015 in the medical oncology unit of the YGH. Results: We included 265 patients for the study following at least one year of CT. The mean age at the onset of CT was 35.9 ± 6.9 years. Most of the patients had fewer than 2 deliveries (68.3%). Intraductal carcinoma was the most frequent histological lesion (90.6%) and most often diagnosed in advanced stages (73.5%). As per CT, the FAC protocol was the most used (44.5%). The menstrual cycles of the patients were more regular prior to the onset of chemotherapy (89.4% vs. 58.9%), while the mean period of resumption of menstrual activity following cessation of chemotherapy was 6.3 ± 2.0 months. Chemotherapy-related amenorrhoea was observed in 29.1% of patients after 12 months of treatment. More than half of these women (51.3%) complained of a drop in libido and 6.4% achieved pregnancy within 13 months following cessation of chemotherapy. Conclusion: Following chemotherapy for BC, menstrual cycle disorders are more frequent and this can affect the patients’ reproductive potential. Fertility consultations should be integrated into the management plan of such patients.
文摘Premature infants are at risk for developmental delay. We assessed the psychomotor development of children born before 37 weeks of gestation.?Methods:?This was a descriptive cross-sectional study conducted in the Pediatric Department of the Yaounde Gynaeco-Obstetric and Pediatric Hospital from January to May 2018. We used the Denver II scale to assess the psychomotor development of children born premature aged 9 months to 6 years. Children born between January 2012 and April 2017 at a gestational age strictly below 37 weeks of gestation were included. Using logistic regression, we searched for perinatal factors associated with abnormalities of psychomotor developmental.?Results:?We included 50 children in our study, 60% of whom were boys, giving a sex ratio of 1.5. The mean age was 25 ± 19.5 months. The mean gestational age was 33 ± 2.2 weeks and the mean birth weight was 2178.68 ± 748.01 g. The average Developmental Quotient of the population was 108. Six children (12%) had a global developmental delay (DQ ?70), 22% of the children had a language delay. Convulsion was associated with motor delay (OR = 16;P = 0.03), and pregnancy monitoring a protective factor for language delay (P = 0.02).?Conclusion:?Improving perinatal care remains a preoccupying issue. The assessment of psychomotor development should be done until early childhood to enable early diagnosis of learning disabilities.

文摘The number of interurban and urban-rural travelers in the city of Yaounde has recently exceeded one hundred thousand per year, yet surprisingly few studies have assessed travelers’ behavior, illness, and risk factors in a sanitary risks setting. Particularly scarce are surveys of data spanning travel, return, and follow-up of the same cohort in traveling agencies and parks. This study examines behavior and illness among travelers moving from Yaounde to other urban and rural areas of Cameroon and beyond. Patterns of behavior connected to a type of travel and illness are characterized in this study so as to identify risks factors and provide background data for pre-travel advice in our traveling agencies. Assessing the susceptibility that imported cases could pose to the national response to infectious diseases depends both on public health, health services and infrastructures. The six agencies assessed: Nvan, Mokolo, Tongolo, Biyem Assi, Mimbowman and Etoudi reveal that the sanitary infrastructures for faecal and urinary disposal are not sufficient and more so, some agencies do not keep enough cleanliness, let alone provide adequate hand washing material as prescribed by national and international concerns to combat the global health challenges. This could be an impediment to travellers going out or inside of the city, and could be a preponderant mechanism for the spread of infectious disease as presented by the infectious diseases isolated and identified in the health districts around the travelling agencies.
文摘Introduction: Patient satisfaction is a quality-of-care measure and reveals patients’ appreciation of healthcare delivery. We sought to measure patient satisfaction following major gynaecological surgeries in 2 University Teaching Hospitals in Yaounde, Cameroon. Methods: This study was a cross-sectional, prospective study over 9 months (October 1st, 2018, to June 30th, 2019) at the Yaounde Gynaeco-Obstetric and Paediatric Hospital (YGOPH) and the Yaounde Central Hospital (YCH). By administering a modified Surgical Satisfaction Questionnaire (SSQ-8) via phone call 6 months after surgery, we appreciated and scored key aspects linked to patient satisfaction and obtained information on post-operative complications. Data were analysed using Microsoft Excel 18 and SPSS 21 setting significance at p Results: We recruited 72 patients aged 24 to 68 years. Our participants had a mean satisfaction score of 26 ± 7.854 (59.7% satisfied and 40.3% dissatisfied). All aspects tested on the SSQ-8 questionnaire influenced patient satisfaction. Patients who said they were satisfied with pain control after surgery (OR = 0.207 CI = 0.070 - 0.609, p = 0,003), and with surgical results in the SSQ-8 questionnaire (OR = 0.053, CI = 0.011 - 0.254, p < 0.001) achieved statistically significant post-operative satisfaction. Contrarily, patients who were dissatisfied with surgery results (OR = 132.000, CI = 15.256 - 114.131, p < 0.001) and those who developed complications (OR = 7.922, CI = 2.241 - 28.004, p < 0.001) were significantly dissatisfied with surgery. Additionally, 47.2% declared a poor post-operative current health status versus 52.8% who claimed a good post-operative current health status. Following multivariate analysis, satisfaction with the results of surgery (OR = 0.071, CI = 0.008 - 0.657, p = 0.020) and the occurrence of complications (OR = 7.284, CI = 1.146 - 46.273, p = 0.035) were the main determinants of patient satisfaction. Patient current health status evolved similarly to patient satisfaction and especially by satisfaction with time taken to resume work (OR = 0.039, CI = 0.004 - 0.398, p = 0.006) and pre-operative exercise routine (OR = 0.038, CI = 0.002 - 0.678, p-value = 0026). Conclusion: Patient satisfaction with elective gynaecological surgery is low and determined by post-operative experiences and the occurrence of complications. Also, patients self-reported current health status tends to evolve similarly to satisfaction following surgery.
文摘<strong>Background/Aim:</strong> Abrikossof’s tumor or granular cell tumor is a rare tumor. The cervicofacial localization is the most common. The aim of this report case was to show a rare case of nasal localization, to the 48-year old patient, treated in poor medical condition. <strong>Case presentation:</strong> The patient consults late with enormous nasal mass involving for five years. After biopsy and facial CT-scan, a surgical procedure was performed. The evolution was good and the final pathology confirms the diagnosis. The objective of this case report was to show the originality of the presentation and the difficulties for management in poor medical environment. <strong>Conclusion:</strong> Abrikossof’s tumor is a rare benign tumor but whose preferential development occurs at the expense of the ENT sphere. Large forms remain the preserve of poor environments. The diagnosis is pathological and the treatment is surgical.
文摘Markets, whose creation needs heavy investment, are seen as centres for economic and financial transactions. To this effect, they play an important role in the survival of city dwellers as well as the embellishment of the city. In 2006, Nsam market was created in the Nsam quarter Yaounde with little financial concentration. Over the years, this market has outlived its usefulness to the extent that its present functioning is an eyesore. Amongst the causes to this are the facts that, the market was created following no predefined standards, the city has grown and the market can no longer handle the dependent population. From field observations, this study aimed at proposing a complete renovated plan for the Nsam market in Yaounde, Cameroon. The study relied on secondary and primary sources of data collected and treated following some pre-set standards. These data enabled an analysis of the diagnosis of the situation prevailing there where it led to the conclusion of a complete renovation of the market. This renovated market is expected to better the working conditions of traders, create more jobs which will boost revenue collection and embellishment of the city amongst others.
文摘<strong>Introduction: </strong><span style="font-family:""><span style="font-family:Verdana;">Prolonged Second Stage of Labor (SSL) is known to increase maternal and foetal morbidity. We, therefore, aimed to assess for the occurrence of complications of the SSL in relation to its duration in primiparous women in Yaounde. </span><b><span style="font-family:Verdana;">Methods:</span></b><span style="font-family:Verdana;"> It was a cohort study carried out at the Yaounde Gynaeco-Obstetric and Paediatric Hospital over a period of 6 months, from December 19, 2018 through May 3, 2019. We included for the study nulliparous pregnant women with singleton pregnancies and normal uteri. Data collected were analysed using EPI info 7 and SPSS version 2.0 software.</span><b><span style="font-family:Verdana;"> Results:</span></b><span style="font-family:Verdana;"> Amongst 327 nulliparas, the SSL lasted more than one hour in 120 (36.7%), and more than two hours in 42 (12.8%).

文摘Introduction: Surgical management of adrenal tumors has greatly improved over the past years, with laparoscopic adrenalectomy being the gold standard. However, Open adrenalectomy is indicated in large adrenal tumors, malignant tumors and large phaeochromocytomas. We report surgical outcomes of 18 cases of functional adrenal tumors from 2007 to 2022. Methods: We conducted a retrospective cross-sectional and descriptive study in three tertiary hospitals in Yaounde, Cameroon. We reviewed files of patients who underwent adrenalectomy over a period of 15 years from July 2007 to July 2022. Clinical and diagnostic components of adrenal tumors, indications and surgical outcomes were analyzed. Results: A total of 18 patients were included in our study. The average age of patients was 38.33 years, with a female-to-male sex ratio of 2:1. Weight gain (72.2%) was the most represented clinical sign. The secretory nature of tumor and malignancy represented 55.5% and 33.3% of the operative indications and all 18 (100%) of the patients had open adrenalectomy. Vascular injury was the most common intraoperative complication with 5.63%, while acute adrenal insufficiency (16.7%) was the most common post-operative complication. The average tumor size was 6.22 cm and the mean duration of hospitalization was 11.61 days. Adenoma 7 (38.9%) and adrenocortical carcinoma 5 (27.8%) were the frequent histological types. One patient died two months post-surgery from anemia-related complications. Conclusion: The success of adrenal surgery is linked to multidisciplinary patient care and the experience of the surgeon. Conventional surgery still has indications with satisfactory short- and medium-term results in our context.

文摘A baseline study involving analyses of subsurface water samples from the Mingoa river basin (longitude: 11°30′E;latitude: 3°52′N) in migmatitic complex in Yaounde Cameroon (central Africa) was carried out to assess their suitability for drinking, domestic and agricultural purposes. Study results show that pH is ranged between 5.1≤ pH ≤ 5.8 and then, induces acidic waters. Groundwater samples are generally characterized by low conductivity values, of which 100% are within the range (55 ≤ EC ≤ 1500 μS/cm). The mean values of the major cations (Ca2+, Mg2+, Na+, K+) and anions (SO42– , Cl–, HCO3– ) are all within the World Health Organization (WHO) standards. Two of the springs sampled have nitrate (NO3– ) contamination. Even though contamination and acidic waters exist in some of the springs, the majority of the springs are excellent for agricultural and domestic purposes. Assessment of the groundwater for agricultural irrigation revealed two main categories. These are low salinity-low sodicity (C1-S1) and medium salinity-low sodicity (C2-S1), using the US Salinity Laboratory (USSL) classification scheme. As much as all of the samples plotted in the “excellent to good” and “good to permissible” categories on the Wilcox diagram. The groundwater in the study area may therefore be regarded as good for irrigation activities. The major identifiable geochemical processes responsible for the evolution of the various ions are mineral weathering, chemical reactions and anthropogenic activities.
文摘Located in central Africa, Cameroon offers a wealth of solar power opportunity. The public lighting in the capital city Yaounde is an example of solar energy promotion. The purpose of this paper is among other things aiming at assessing the solar energy resources of central Africa and making sure it can be used optimally at least for public lighting. Based on the knowledge from data collected and field experience for three years, the authors will assess the implementation of the technology and show how the use of solar energy can solve some problems in the city of Yaounde even when the area is grid connected. This paper will also identify actions for improved access to sustainable, friendly, affordable solar energy services to users, as well as a significant improvement of energy infrastructure and energy efficiency in the city. The authors will also address issues on identified obstacles for the promotion of solar energy in order to help the cities in sub Saharan countries to develop a vision aiming at developing good solar energy policy and better contribute to fight against poverty and climate change.
文摘Background: The incidence of intracranial metastases (ICMET) has been steadily rising, and its frequency with respect to primary brain tumours is relatively high. Objective: The objectives of this study were to elucidate the current epidemiology and describe the clinical, diagnostic and therapeutic features of ICMET in Yaounde. Method and findings: A descriptive cross-sectional study was done in the neurosurgery departments of the General and Central Hospitals of Yaounde during the period from January 2016 to December 2022. We included all medical booklets of patients admitted for a tumoral intracranial expansive process with our target population being patients with histological evidence of ICMET, and did a retrospective inclusion of data using a pre-established technical form aimed at collecting sociodemographic data, clinical data, paraclinical data, and the treatment procedures. Analysis was done using the SPSS statistical software. A total of 614 cases of intracranial tumors were included among whom 35 presented histological evidence of ICMET. This gives a frequency of 5.7%. The sex ratio was 0.94, the mean age was 55.68 +/- 14.4 years, extremes 28 and 86 years and the age range 50 - 59 was affected in 28.57% of cases. The clinical presentation included signs of raised intracranial pressure (headache, blurred vision, vomiting) in 26 cases (74.3%), motor deficit 48.6%, seizures 17.1%. The mode of onset was metachronous in 71.4% and synchronous in 28.6%. The imaging techniques were cerebral CT scan in 82.9%, cerebral MRI in 40%, TAP scan in 22.9%. The metastatic lesions were supratentorial in 94.3% and single in 62.9%. The primary cancers found were breast cancer (31.4%), lung cancer (25.7%), prostate cancer (17.1%), thyroid cancer (5.7%), colon cancer (2.9%), and melanoma (2.9%). The therapeutic modalities were total resection (68.6%), radiotherapy (37.1%). Conclusion: Intracranial metastases are relatively frequent. There is a female sex predominance and the age group 50 - 59 years is the most affected. Brain metastases mostly occur in patients with a history of known primary tumor. The clinical signs mainly include signs of raised intracranial pressure, motor deficit, seizures and mental confusion. Cerebral CT Scan is the main imaging technique used. Most of the lesions are single and supratentorially located. The primary cancers most represented include breast cancer, lung cancer and prostate cancer. Surgery is the main treatment procedure. The adjuvant treatment (radiotherapy, chemotherapy) was limited.
文摘<strong>Introduction:</strong> Endoscopic endonasal surgery is currently a validated therapeutic modality in most nasal sinus disorders. In developed countries, this practice is common and sees the indications constantly reviewed;In sub-Saharan Africa, this surgical technique is popularized. The external pathways are morbid and not very functional. In our daily practice at the Yaounde General Hospital (YGH), this technique is still in its infancy. Gradually it’s entering our habits and sees its indications increases. Through this study, we are reporting readily available data from our experience. <strong>Objectives:</strong> The objective was to study the practice of endoscopic endonasal surgery in our setting. <strong>Patients and Method:</strong> This was a cross-sectional, descriptive, retrospective study. The site of study was the ear-nose and throat service of Yaounde General Hospital. The study was conducted from January 2013 to December 2020, for an 8 years basis. The sampling was consecutive. We included in this study all patients operated on for a nasal sinus disease by the endoscopic endonasal modality. We excluded patients with incomplete files, as well as those who had a complementary transfacial approach during the same operation. The data were collected on prepared questionnaire. Data analysis is done with ssps 23.0 software. <strong>Results:</strong> We recruited 30 cases, out of a total of 330 interventions carried out in our department. The prevalence of this surgery in our activity was 9%. Male and female had equal ratio of 50%. The most represented age group was 30 - 40 years (33.3%). All the patients had a facial sinus CT scan, we did not note any anatomical variant as risk. Two patients of our sample size had a history of sinus surgery, treated externally. Chronic maxillary sinusitis was the surgical indication in 36.7%, followed by Killian antro-choanal polyps in 13.3%, nasosinus polyposis in 13.3% and all performed under general anesthesia. The most performed procedure was unilateral mean meatotomy with 43.33% followed by bilateral mean meatotomy with 20%, ethmoidectomy 13.3%, bimeatotomy 10%. The admission lasted for 2 days. 100% of patients had a previous nasal tamponade at the end of the intervention. The tamponade was removed on the second postoperative day in 100% of patients. 16.7% of patients presented with complications of low abundance postoperative bleeding. All patients noted clinical improvement over the initial symptoms postoperatively. <strong>Conclusion:</strong> Endoscopic endonasal surgery is experiencing slow but certain progress in our daily practice. The operated patients are young, chronic maxillary sinusitis is the main indication, the most performed procedure is the unilateral mean meatotomy. The operation goes uneventful with satisfactory prognosis. A study with a larger sample is necessary in order to refine our results. The practice remains limited by the technical platform, which needs to be strengthened, in order to optimize the practice.
