Methodology: It was a retrospective and descriptive study from January 2011 to December 2014 and involved all patients hospitalized during the study period. Results: The study included 21 patients out of 1738 hospitalized patients, with a prevalence of 1.21%. The mean age was 38.57 years with extreme ages of 18 and 64 years. The sex ratio was 0.40. Risk factors found in the study were oral contraception (19.05%), overweight (19.05%), smoking (14.28%), HIV (4.76%) and heart failure (4, 76%). 61.90% (n = 13) had isolated pulmonary embolism, 38.09% (n = 8) had venous thrombosis and pulmonary embolism association. Through the chest angio-CT, 28.57% of obstructions were located at the left branch of the pulmonary artery, 9.52% at the right branch and 61.90% were bilateral obstructions. Four deaths were recorded, all in a context of massive pulmonary embolism, with a fatality rate of 19.05%. Conclusion: Pulmonary embolism is a serious and common disease, often difficult to diagnose. It is a cardiovascular emergency and requires immediate and adequate care.展开更多

We initiated this study with the aims of determining the epidemiological, clinical and therapeutic aspects of TDI at Gabriel Toure University Hospital. This was a retrospective study from January 1999 to June 2021 that included all patients who presented a diaphragmatic injury consecutive to abdominal and/or thoracic trauma. In 22 years and 6 months, 46 cases of TDI were collected. They represented 0.17% of hospitalizations, 0.26% of surgical emergencies and 5.5% of thoraco-abdominal traumas. The average age was 31.69 years with a sex ratio of 3.2. Criminal stabbings accounted for 56.5% and TRA for 19.6%. Penetrating injuries accounted for 78.3% of cases. The parietal lesion was thoracic in 21 cases (45.7%), abdominal in 19 cases (41.3%) and thoraco-abdominal in 6 cases (13%). The chest X-ray, performed in 15 patients, showed an intrathoracic gas bubble (4 cases) and hemothorax (6 cases). Diagnosis of diaphragmatic lesion was preoperative in 21.7% (10 cases). The diaphragmatic breach was on the left side in 65.2% (30 cases) and the average size was 3.17 cm. Laparotomy was performed in 89.1%, thoracotomy in 4.4% and thoraco-laparotomy in 6.5% of cases. The surgical procedure consisted of reduction of the herniated viscera in 15.2% (7 cases) and closure of the diaphragmatic breach with non-absorbable sutures in 82.6% (36 cases). Chest tube drainage was performed in 73.9%. The average length of hospital stay was 9.8 days. Mortality was 13.04%. Conclusion: Traumatic diaphragmatic injury is rare but its frequency is increasing in our country. It most often affects the young man victim of assault or TRA. This type of trauma is rarely isolated;you have to think about it in case of any thoraco-abdominal trauma. The treatment is surgical. The prognosis depends on the severity of the associated lesions.展开更多

Varices bleeding represented a prevalence of 5.5% among hospitalized patients during the same period. The average age of our patients was 46.58 ± 15.09 years. The male sex was more reported in our study with a prevalence of 67.5%. At admission, 63.2% had clinical anemia, 58.4% low arterial pressure and 50.6% hemoglobin rate less than 7 g/dL. Blood transfusion was indicated in 47 patients (61%). The mortality rate was 23.4% and was comparable in both groups (p = 0.0990). Early rebleeding was significantly observed in the case of transfusion (p = 0.0452). Hepatic encephalopathy was the leading cause of death of our patients with 72.2%. <strong>Conclusion:</strong> Digestive bleeding by esophageal varices is a worsen complication in cirrhosis in hospital setting. Transfusion has not significantly improved the prognosis of our patients.展开更多

WHO in its global report on violence and health estimates that in 2000, 1.6 million people worldwide died as a result of self-harm, interpersonal or collective violence, resulting in an overall rate adjusted by age of 28.8 per 100,000 population. Because of the seriousness of this phenomenon and the heavy socio-economic and health consequences that they generate, it seemed important to us to undertake this study, which aimed to study the deliberate injuries in the emergency unite of the Gabriel Touré Teaching Hospital in Bamako. Material and methods: This was a descriptive and cross-sectional study with a prospective study from September 1st, 2016 to August 31st, 12 months, covering 295 patients, including any patient received for voluntary injury consultation with a workable medical record and/or a full investigation record with or without requisition. Our data were collected on individual survey cards and subsequently analyzed with Word, Excel, IBM SPSS Statistics 22 software. Results: The majority of victims of assault and bodily injury were male with 83.1%;with a sex ratio of 4.9, the 18 to 28 age group was the most concerned with 163 cases of the 295 cases in our study, 55.2%. The extremes were 6 and 100 years old with an ectype at 11.08. The most affected ethnic group was Bambara with 38.6% (n = 114) followed by Fulani with 15.6% (n = 46). Students were the most affected at 24.7% (n = 73), followed by traders at 10%. The victims coming from outside Bamako are the most predominant with 22.4% (n = 66) followed by those of commune IV of Bamako 15.6% (n = 46). In 92.2% of the cases the mechanism was direct with n = 272. Of the lesions recorded in our study, wounds came first with 53.2% of cases. Radiography was the most used imaging at 44.7% (n = 89) followed by computed tomography at 34.7% (n = 69). The hemoperitoneum objectified by abdominal ultrasound represented 29.3% (n = 12). Fractures embarrure associated with bruising-hemorrhagic bruises were the most predominant with 13.4% (n = 10) objectified by brain scan. Conclusion: We note that the phenomenon of violence has reached worrying proportions, especially among young adults, particularly among students and is observed in all so-cio-professional layers. The polymorphism of these injuries caused by the predominant use of knives must draw the attention of our authorities to take measures to reduce these aggressions.展开更多

文摘Traumatic diaphragmatic injury (TDI) is rare and is most often the result of a traffic road accident (TRA) or an assault. We initiated this study with the aims of determining the epidemiological, clinical and therapeutic aspects of TDI at Gabriel Toure University Hospital. This was a retrospective study from January 1999 to June 2021 that included all patients who presented a diaphragmatic injury consecutive to abdominal and/or thoracic trauma. In 22 years and 6 months, 46 cases of TDI were collected. They represented 0.17% of hospitalizations, 0.26% of surgical emergencies and 5.5% of thoraco-abdominal traumas. The average age was 31.69 years with a sex ratio of 3.2. Criminal stabbings accounted for 56.5% and TRA for 19.6%. Penetrating injuries accounted for 78.3% of cases. The parietal lesion was thoracic in 21 cases (45.7%), abdominal in 19 cases (41.3%) and thoraco-abdominal in 6 cases (13%). The chest X-ray, performed in 15 patients, showed an intrathoracic gas bubble (4 cases) and hemothorax (6 cases). Diagnosis of diaphragmatic lesion was preoperative in 21.7% (10 cases).

文摘In recent years,the state has vigorously promoted the construction of cultural heritage-themed tourism routes.Policies such as the Notice on the Construction of China Cultural Heritage-Themed Tourism Routes and the Dongpo Journey-China Cultural Heritage-Themed Tourism Route Master Plan have been successively issued,encouraging the creation of cultural-tourism integration projects that primarily feature immovable cultural relics and combine specific themes.However,current digital tours at cultural heritage sites often suffer from fragmented cultural knowledge transmission,a lack of personalized user experience,and insufficient contextual learning effects.To address these issues,this study takes the“Dongpo Travel”digital tour mini-program as a case study to explore the design of a thematic tourism route digital tour platform that integrates ontology and user profiling.The platform achieves structured transmission of Dongpo cultural knowledge by constructing historical relic tour maps,improving cultural tourism route services,setting up post-tour incentive mechanisms,and developing contextual learning modules.This meets the personalized travel needs of different users and helps tourists deepen their cultural learning during visits.Practice shows that the platform can operate stably at the Su Causeway in the West Lake Scenic Area,covering approximately 27 Dongpo cultural sites and serving over 500 people daily.It not only promotes the revitalization and inheritance of Dongpo cultural heritage but also provides a replicable solution for the digital transformation of the cultural tourism industry.Additionally,it effectively enhances the efficiency of contextual learning at cultural heritage sites and offers a reference for the construction of similar thematic tourism route digital tour platforms.

文摘The approaches of constructing ecological tourist destinations for health preservation are introduced from 8 aspects,that is,resources,environment,cultures,services,facilities,management,marketing and education.Meanwhile,this study states that the key of building such tourist destinations is the health-preservation environment system,including ecological environment,cultural environment and social environment.
文摘The combination of ornamental function and recreational function should be taken into account in road landscape design of scenic area.The theme characteristic should be highlighted by designing techniques.Roads in scenic area should be used to lead tourists' behavior according to people's behavioral psychology.With Five Dragon Temple Cultural Park as case study,starting from its geographic location and establishment concept,the paper had extracted design theme of Five Dragon Temple Cultural Park.Profound religious cultural connotation had been given to the cultural park with Chinese traditional religion and "Five Elements" theory as the inspiration.It designed five main roads with different colors which represented five elements covering "gold,wood,water,fire and earth".Different scenic areas had been linked together by five man roads,forming a road landscape pattern of "meeting of five dragons".Then,flowering plants had been collocated along the five roads which were Vatica astrotricha,Punica granatum,Prunus serrulata,Morus alba and Osmanthus fragrans,creating theme-based road landscape not only representing religious significance but also corresponding with "Five Elements" theory.
