Its diagnosis is often based on a combination of clinical and biological arguments, and confirmed by bacteriology which is rarely available. In Congo there is little published data on this entity. Objectives: To describe the epidemiological, diagnostic, and progression characteristics of peritoneal tuberculosis at the university hospital center in Brazzaville. Patients and Methods: This study is a descriptive and retrospective analysis conducted from January 1, 2015, to December 31, 2021, in the Gastroenterology and Internal Medicine department of the CHU of Brazzaville. It included all patients hospitalized during this period with a confirmed diagnosis of peritoneal tuberculosis, encompassing 54 records that met the inclusion criteria. Results: Out of the study period, 54 records that fulfilled the inclusion criteria were analyzed. The annual incidence of peritoneal tuberculosis was 7.7 patients, with a prevalence of 1.4%, showing a male predominance of 61% and an average age of 39.93 ± 14.62 years. The primary symptoms were abdominal bloating and abdominal pain, present in 100% and 74% of cases, respectively. The clinical presentation was primarily characterized by febrile ascites observed in all patients. HIV co-infection was noted in 29.6% of cases. Anemia was present in 79.6% of patients, and an elevated sedimentation rate was observed in 74% of cases. The tuberculin skin test returned positive in 50% of cases. The ascitic fluid was exudative, rich in proteins and white blood cells (exceeding 1000/mm3, predominantly lymphocytes) in the majority of cases (100%, 83.3%, 83.3%, respectively). The diagnosis was deemed highly probable based on the clinical and paraclinical signs and the favorable response to treatment in 79.6% of cases. There were instances of pleural involvement (33.3%) and lymph node involvement (pulmonary 22.2% and lymph node 16.6%). Treatment outcomes were favorable in 37% of cases, with a mortality rate of 9%. Conclusion: Peritoneal tuberculosis is prevalent in Brazzaville, predominantly affecting young males. The diagnosis relies chiefly on a combination of clinical, paraclinical, and progression indicators.展开更多
In the four decades from 1951 to 1990, the six provinces or autonomous regions (Xinjiang, Gansu, Qinghai, Ningxia, Xizang and Nei Monggol) reported a total of 26 065surgical cases of hydatid disease, most of which wer...In the four decades from 1951 to 1990, the six provinces or autonomous regions (Xinjiang, Gansu, Qinghai, Ningxia, Xizang and Nei Monggol) reported a total of 26 065surgical cases of hydatid disease, most of which were reported in the recent decade. About one third of the patients was children and adolescents under 15 years old. So far, cystic hydatid infections of local origin have been confirmed in 22 provinces, autonomous regions and municipalities in the whole nation. Findings of X-ray examination and real-time B-mode ultrasonography in agricultural and pastoral areas of Xinjiang, Gansu, Qinghai,Ningxia and Xizang showed that the morbidity rate of hydatidosis in human population varied between 0.5% and 4.5%. The main animal intermediate host in all these regions is sheep, the morbidity of which varied between 3.3% and 90%. The infection rate of adult Echinococcus granulosus in dogs varied between 7% and 71%. The high-risk period for humans contracting hydatid disease is the pre-school age. Direct contact of children with dogs and ingestion of water, vegetables and foods contaminated by worm eggs are the chief mode of transmission for human hydatidosis. The common practices of home slaughter and of feeding dogs on offal containing hydatid cysts facilitate the life cycIe of the parasite.On the basis of hydatid control efforts for several years, the Ministry of Public Health promulgated officially the '1992-1995 National Programme for Hydatid Disease Control'in April, 1992, and pilot studies in which the control of hydatidosis is composed of extensive health education, sanitation of slaughtering and management and deworming of dogs are being established.Cystic echinococcosis has wide distribution in China and is a major public health problem in hyperendemic areas, poses a great threat against people's health and influences the development of livestock husbandry. This problem has received great attention from the medical and veterinary departments. In the rencent decade great efforts have been made in the epidemiology, parasitology and clinical treatment of echinococcosis, resulting in a better understanding of the disease and procedures effective in bringing about control of the disease展开更多

Demographic data, past history, ophthalmic examinations and other laboratory tests were analyzed.RESULTS: One hundred and ninety-nine uveitis patients were enrolled in this study, including 134(67.3%) males and 65 females(32.7%) with an average age of 41.0 ±15.1y. The anatomical distribution included103(51.8%) cases of anterior uveitis, followed by panuveitis(65, 32.7%), posterior uveitis(29, 14.6%) and intermediate uveitis(2, 1.0%). Of the 98(49.2%) non-idiopathic cases, there were 10.1% Behcet’s disease,9.5% Vogt-Koyanagi-Harada(VKH) syndrome, 7.5%infectious uveitis, 7.5% traumatic uveitis and 3.5%postoperative uveitis.CONCLUSION: Idiopathic anterior and posterior uveitis,Behcet’s disease, VKH syndrome, infectious uveitis and traumatic uveitis are the most common uveitis entities in a secondary hospital in southern China. Additional measures should be taken to prevent infectious and traumatic uveitis.展开更多

Methods: The authors added a question in 2012 on e-cigarette in the yearly survey on tobacco consumption in Paris schoolchildren. The study is conducted on a randomly selected sample from 2% of classes since 1991. Results: 277 (8.1%) of the 3409 schoolchildren studied (including 575 non responders to this question) reported having had an experience with e-cigarette. Experimentation rate is 6.4% among the 12 - 14-year-old, 11.8% among the 15 - 16-year-old and 9% among the 17-year-old schoolchildren. Among the 12 - 14- year-old schoolchildren, 64.4% of e-cigarette experimentation was by non-smokers. Of the 17-year-old teenagers who had used e-cigarettes, 12.4% were non-smokers. For the whole population, 33.2% of those having tried e-cigarette are non-smoker, 22.7% occasional smoker, 3.6% ex-smoker and 40.4% daily smoker. Those who experiment cannabis, shisha or binge-drinking are more frequently users of e-cigarette. In the smoker group, there is an inverse trend of rela- tionship between the readiness to quit tobacco and the rate of use of e-cigarette. Conclusion: For teenager’s, e-cigare- ttes have become not a product to aid quit tobacco but a product for experimentation and initiation of cigarette use. Regulation is urgently needed to control the emergent use of this new tobacco product by children.展开更多

The twins were asked to provide biological samples, questionnaires, and data access to patient files and public registries. Biological samples were collected via a mobile laboratory, which allowed for immediate centrifugation, fractionation, and storage of samples. The mean time from collection of samples to storage in the -80 °C mobile freezer was less than one hour. The diagnoses where validated using the Copenhagen diagnostic criteria.RESULTS: We identified 159 MZ IBD twin pairs, in a total of 62 (39%) pairs both twins agreed to participate. Of the supposed 62 IBD pairs, the IBD diagnosis could be confirmed in 54 pairs. The cohort included 10 concordant pairs, whereof some were discordant for either treatment or surgery. The 10 concordant pairs, where both pairs suffered from IBD, included eight CD/CD pairs, one UC/UC pair and one UC/IBDU pair. The discordant pairs comprised 31 UC, 5 IBDU (IBD unclassified), and 8 CD discordant pairs. In the co-twins not affected by IBD, calprotectin was above 100 μg/g in 2 participants, and above 50 μg/g in a further 5 participants.CONCLUSION: The presented IBD twin cohorts are an excellent resource for bioinformatics studies with proper adjustment for disease-associated exposures including medication and inflammatory activity in the co-twins.展开更多

Methods： Epidemiological, microbiological, and molecular methods were performed to identify risk factors and describe the ecology of E. coli O157：H7 in the enviromnent. Results： From May to September, in 1999, 99 cases of E. coli O157：H7 infection were confirmed. Fifty-six patients were enrolled in the case-control study. Bad personal health habits and poor sanitary conditions in the kitchen were associated with increased risks of infection, whereas hand washing was protective. The household survey indicated that residents in the epidemic region during the outbreak had higher than expected rates of diarrhea. The total E. coli O157：H7 carrier rate in the livestock was 12.36%（22/178）, specifically 19.15% in cattle, 12.50% in goat, and 11.11% in swine. Numerical analysis of pulsed-field gel electrophoresis（PFGE） profiles divided strains into two clusters with 77.5% homology. One cluster contained 11 strains isolated from diarrheal patients, foods, and animals. The other cluster comprised 10 strains from patients and environment. Conclusion： In a large outbreak of E. coli O157：H7 infection among predominantly elderly residents in Xuzhou, high rates of carriage of E. coli O157：H7 among host animals most likely resulted in contamination of the environment, thereby leading to the outbreak. Effective and preventive control measures should be taken to avoid contamination, including environmental and family health improvement, good personal hygiene, and safe food handling practices.展开更多

文摘Creatine kinase is a muscle enzyme that has been reported at various levels in different studies involving patients with amyotrophic lateral sclerosis.In the present retrospective case-control study,we included 582 patients with amyotrophic lateral sclerosis and 582 age-and sexmatched healthy controls.All amyotrophic lateral sclerosis participants received treatment in the Department of Neurology,West China Hospital,China,between May 2008 and December 2018.Serum creatine kinase levels in patients with amyotrophic lateral sclerosis were significantly higher than those in healthy controls.Subgroup analysis revealed that serum creatine kinase levels in men were higher than those in women in both amyotrophic lateral sclerosis patients and healthy controls.Compared with patients with bulbar-onset amyotrophic lateral sclerosis,patients with limb-onset amyotrophic lateral sclerosis had higher creatine kinase levels.Spearman's correlation analysis revealed that serum creatine kinase levels were not correlated with body mass index,Amyotrophic lateral Sclerosis Functional Rating ScaleRevised score,or progression rate.After adjusting for prognostic covariates,higher log creatine kinase values were correlated with higher overall survival in the amyotrophic lateral sclerosis patients.We also investigated the longitudinal changes in serum creatine kinase levels in 81 amyotrophic lateral sclerosis patients;serum creatine kinase levels were decreased at the second blood test,which was sampled at least 6 months after the first blood test.Together,our results suggest that serum creatine kinase levels can be used as an independent factor for predicting the prognosis of amyotrophic lateral sclerosis patients.This study received ethical approval from the Ethics Committee of West China Hospital,China(approval No.2015(236))on December 23,2015.

文摘Both case-control and cohort studies were undertaken from July 1,1969 to June 30,1983 to ascertain whether exposure to chloroprene increases the risk of cancer.Fifty-five cases of cancer deaths were verified,16 of which had histories of exposure to chloroprene ranging from 3 to 23 years(median 11 years)with a latent period of 8-27 years,except for one case of 3 years(median 12.5 years).Fifty-four pairs were obtained by matching the cancer deaths to noncaneer deaths in accordance with strict requirements.The odds ratio for the paired data was 13,x^2=8.64,P <0.005.The average age at death from cancer of workers exposed to chloroprene was 12.7 years younger than that of unexposed workers,t'=2.98,P<0.001.The total cohort consisted of 1213 persons,among whom 149(11.6%)had histories of exposure for over 25 years,381(31.5%) for over 20 years,and 852(70.2%) for over 15 years.The SMR for the total cohort was 2.38(P <0.01),and all SMRs for the high-exposure occupations were of significance(P<0.05or P<0.01),in contrast to those of the low-exposure groups whose SMRs were low or zero.Thus, a dose-response relationship existed.Among the high-exposure occupations,maintenance me- chanics seem to have the highest risk of cancers,and SMRs for liver,lung,and lymphatic cancers were significant in this group.These results suggested that chloroprene exposure increases the risk of developing cancer.1989 Academic Press,Inc.

文摘Peritoneal tuberculosis is the most common digestive location of tuberculosis. Its diagnosis is often based on a combination of clinical and biological arguments, and confirmed by bacteriology which is rarely available. In Congo there is little published data on this entity. Objectives: To describe the epidemiological, diagnostic, and progression characteristics of peritoneal tuberculosis at the university hospital center in Brazzaville. Patients and Methods: This study is a descriptive and retrospective analysis conducted from January 1, 2015, to December 31, 2021, in the Gastroenterology and Internal Medicine department of the CHU of Brazzaville. It included all patients hospitalized during this period with a confirmed diagnosis of peritoneal tuberculosis, encompassing 54 records that met the inclusion criteria. Results: Out of the study period, 54 records that fulfilled the inclusion criteria were analyzed. The annual incidence of peritoneal tuberculosis was 7.7 patients, with a prevalence of 1.4%, showing a male predominance of 61% and an average age of 39.93 ± 14.62 years. The primary symptoms were abdominal bloating and abdominal pain, present in 100% and 74% of cases, respectively. The clinical presentation was primarily characterized by febrile ascites observed in all patients. HIV co-infection was noted in 29.6% of cases. Anemia was present in 79.6% of patients, and an elevated sedimentation rate was observed in 74% of cases. The tuberculin skin test returned positive in 50% of cases. The ascitic fluid was exudative, rich in proteins and white blood cells (exceeding 1000/mm3, predominantly lymphocytes) in the majority of cases (100%, 83.3%, 83.3%, respectively). The diagnosis was deemed highly probable based on the clinical and paraclinical signs and the favorable response to treatment in 79.6% of cases. There were instances of pleural involvement (33.3%) and lymph node involvement (pulmonary 22.2% and lymph node 16.6%). Treatment outcomes were favorable in 37% of cases, with a mortality rate of 9%. Conclusion: Peritoneal tuberculosis is prevalent in Brazzaville, predominantly affecting young males. The diagnosis relies chiefly on a combination of clinical, paraclinical, and progression indicators.
文摘In the four decades from 1951 to 1990, the six provinces or autonomous regions (Xinjiang, Gansu, Qinghai, Ningxia, Xizang and Nei Monggol) reported a total of 26 065surgical cases of hydatid disease, most of which were reported in the recent decade. About one third of the patients was children and adolescents under 15 years old. So far, cystic hydatid infections of local origin have been confirmed in 22 provinces, autonomous regions and municipalities in the whole nation. Findings of X-ray examination and real-time B-mode ultrasonography in agricultural and pastoral areas of Xinjiang, Gansu, Qinghai,Ningxia and Xizang showed that the morbidity rate of hydatidosis in human population varied between 0.5% and 4.5%. The main animal intermediate host in all these regions is sheep, the morbidity of which varied between 3.3% and 90%. The infection rate of adult Echinococcus granulosus in dogs varied between 7% and 71%. The high-risk period for humans contracting hydatid disease is the pre-school age. Direct contact of children with dogs and ingestion of water, vegetables and foods contaminated by worm eggs are the chief mode of transmission for human hydatidosis. The common practices of home slaughter and of feeding dogs on offal containing hydatid cysts facilitate the life cycIe of the parasite.On the basis of hydatid control efforts for several years, the Ministry of Public Health promulgated officially the '1992-1995 National Programme for Hydatid Disease Control'in April, 1992, and pilot studies in which the control of hydatidosis is composed of extensive health education, sanitation of slaughtering and management and deworming of dogs are being established.Cystic echinococcosis has wide distribution in China and is a major public health problem in hyperendemic areas, poses a great threat against people's health and influences the development of livestock husbandry. This problem has received great attention from the medical and veterinary departments. In the rencent decade great efforts have been made in the epidemiology, parasitology and clinical treatment of echinococcosis, resulting in a better understanding of the disease and procedures effective in bringing about control of the disease

文摘AIM: To investigate the characteristics of uveitis in a secondary hospital in southern China.METHODS: We reviewed all records of patients with uveitis at Hengli Hospital from January 2008 to December2011. Demographic data, past history, ophthalmic examinations and other laboratory tests were analyzed.RESULTS: One hundred and ninety-nine uveitis patients were enrolled in this study, including 134(67.3%) males and 65 females(32.7%) with an average age of 41.0 ±15.1y. The anatomical distribution included103(51.8%) cases of anterior uveitis, followed by panuveitis(65, 32.7%), posterior uveitis(29, 14.6%) and intermediate uveitis(2, 1.0%). Of the 98(49.2%) non-idiopathic cases, there were 10.1% Behcet’s disease,9.5% Vogt-Koyanagi-Harada(VKH) syndrome, 7.5%infectious uveitis, 7.5% traumatic uveitis and 3.5%postoperative uveitis.CONCLUSION: Idiopathic anterior and posterior uveitis,Behcet’s disease, VKH syndrome, infectious uveitis and traumatic uveitis are the most common uveitis entities in a secondary hospital in southern China. Additional measures should be taken to prevent infectious and traumatic uveitis.
文摘The retrospective study by Lew et al(2022)examined the rising hospitalization rates for chronic pancreatitis(CP)and its association with pancreatic ductal adenocarcinoma(PDAC),revealing significant ethno-racial disparities and risk factors.Overweight black men aged 40-59 years and white men over 40 years with higher incomes showed an elevated risk of PDAC among CP patients.The study,which included 14.2 million admissions from 2016-2017,found that 2.6%of adult patients were diagnosed with CP,with white males being the majority.Multivariate regression analysis identified men,black individuals,those aged 40-59 years,and individuals with a body mass index(BMI)between 25 and 29.9 as having an increased risk for CP.Moreover,0.78%of CP patients also had PDAC,with older age and BMI being significant risk factors for developing PDAC in CP patients.The study also highlighted disparities in healthcare access and utilization among different socioeconomic and ethno-racial groups,which may impact the risk and outcomes of CP and PDAC.
文摘Objectives: To explore if the dramatic decrease in price of e-cigarette has transformed this new product into a product used for tobacco initiation among a teenage population. Methods: The authors added a question in 2012 on e-cigarette in the yearly survey on tobacco consumption in Paris schoolchildren. The study is conducted on a randomly selected sample from 2% of classes since 1991. Results: 277 (8.1%) of the 3409 schoolchildren studied (including 575 non responders to this question) reported having had an experience with e-cigarette. Experimentation rate is 6.4% among the 12 - 14-year-old, 11.8% among the 15 - 16-year-old and 9% among the 17-year-old schoolchildren. Among the 12 - 14- year-old schoolchildren, 64.4% of e-cigarette experimentation was by non-smokers. Of the 17-year-old teenagers who had used e-cigarettes, 12.4% were non-smokers. For the whole population, 33.2% of those having tried e-cigarette are non-smoker, 22.7% occasional smoker, 3.6% ex-smoker and 40.4% daily smoker. Those who experiment cannabis, shisha or binge-drinking are more frequently users of e-cigarette. In the smoker group, there is an inverse trend of rela- tionship between the readiness to quit tobacco and the rate of use of e-cigarette. Conclusion: For teenager’s, e-cigare- ttes have become not a product to aid quit tobacco but a product for experimentation and initiation of cigarette use. Regulation is urgently needed to control the emergent use of this new tobacco product by children.

文摘AIM: To describe the establishment of a Danish inflammatory bowel diseases (IBD) twin cohort with focus on concordance of treatment and inflammatory markers.METHODS: We identified MZ twins, likely to be discordant or concordant for IBD, by merging information from the Danish Twin Register and the National Patient Register. The twins were asked to provide biological samples, questionnaires, and data access to patient files and public registries. Biological samples were collected via a mobile laboratory, which allowed for immediate centrifugation, fractionation, and storage of samples. The mean time from collection of samples to storage in the -80 °C mobile freezer was less than one hour. The diagnoses where validated using the Copenhagen diagnostic criteria.RESULTS: We identified 159 MZ IBD twin pairs, in a total of 62 (39%) pairs both twins agreed to participate. Of the supposed 62 IBD pairs, the IBD diagnosis could be confirmed in 54 pairs. The cohort included 10 concordant pairs, whereof some were discordant for either treatment or surgery. The 10 concordant pairs, where both pairs suffered from IBD, included eight CD/CD pairs, one UC/UC pair and one UC/IBDU pair. The discordant pairs comprised 31 UC, 5 IBDU (IBD unclassified), and 8 CD discordant pairs. In the co-twins not affected by IBD, calprotectin was above 100 μg/g in 2 participants, and above 50 μg/g in a further 5 participants.CONCLUSION: The presented IBD twin cohorts are an excellent resource for bioinformatics studies with proper adjustment for disease-associated exposures including medication and inflammatory activity in the co-twins.

文摘Objective： To determine epidemiologic features of an Escherichia coli O157：H7 outbreak occurred in Xuzhou, Jiangsu Province, China in 1999, and assess the incidence of E. coli O157：H7 in diarrhea patients and host animals and its relationship with disease onset, and provide a scientific basis for establishing prevention and control strategies. Methods： Epidemiological, microbiological, and molecular methods were performed to identify risk factors and describe the ecology of E. coli O157：H7 in the enviromnent. Results： From May to September, in 1999, 99 cases of E. coli O157：H7 infection were confirmed. Fifty-six patients were enrolled in the case-control study. Bad personal health habits and poor sanitary conditions in the kitchen were associated with increased risks of infection, whereas hand washing was protective. The household survey indicated that residents in the epidemic region during the outbreak had higher than expected rates of diarrhea. The total E. coli O157：H7 carrier rate in the livestock was 12.36%（22/178）, specifically 19.15% in cattle, 12.50% in goat, and 11.11% in swine. Numerical analysis of pulsed-field gel electrophoresis（PFGE） profiles divided strains into two clusters with 77.5% homology. One cluster contained 11 strains isolated from diarrheal patients, foods, and animals. The other cluster comprised 10 strains from patients and environment. Conclusion： In a large outbreak of E. coli O157：H7 infection among predominantly elderly residents in Xuzhou, high rates of carriage of E. coli O157：H7 among host animals most likely resulted in contamination of the environment, thereby leading to the outbreak. Effective and preventive control measures should be taken to avoid contamination, including environmental and family health improvement, good personal hygiene, and safe food handling practices.
