The objective is to determine hospital frequency, identify favorable factors and key etiologies, and assess the rate of morbi-mortality. <strong>Patients and Method:</strong> This is a retrospective and descriptive study carried out in the general surgery departments of the Teaching Hospitals of Point “G”, Gabriel TOURE and the pediatric surgery department of the Gabriel TOURE University Hospital in Bamako, involving 53 patients. The study ran from January 1, 2005 to December 31, 2007. <strong>Inclusion Criteria:</strong> All cases of postoperative acute evisceration operated. <strong>Non-Inclusion Criteria:</strong> All cases of evisceration of other etiologies. <strong>Results:</strong> The average age was 34.2 years with extremes of 6 and 75 years, the sex ratio was 1.12 in favor of women. The initial clinical picture was peritonitis in 26 cases or 49.1%, occlusion in 16 cases or 30.2% and tumors in 6 cases or 11.3%. The post-operative complications responsible for evisceration were: parietal suppuration 28 cases or 52.8%;digestive fistulas 15 cases or 28.3%;post-operative ascites 4 cases or 7.5%. <strong>Conclusion:</strong> Post-operative acute evisceration is a rare but serious condition due to morbidity and mortality.展开更多

Our objective was to assess the perception of health care stakeholders on the environmental effects related to biomedical waste produced in Teaching Hospitals (CHU) in Togo in 2021. Methods: This was a cross-sectional study held from June 24 to August 28, 2021. It targeted three university hospitals, 340 health care providers and services selected by a probabilistic method with a simple random technique in 25 services, 72 directors, deputy directors, supervisors and heads of services, 27 collection and incineration agents selected by a non-probabilistic method with a reasoned choice technique, 44 patients and attendants and 36 householders of neighboring residents selected by a non-probabilistic method with an accidental choice technique. Variables such as the spreading of disease vectors, soil, air and water contamination, the presence of unpleasant odors and unsightly living conditions were assessed. Results: According to the respondents, biomedical waste causes the proliferation of vectors (55.3%), an unsightly environment inside the hospital (47.1%), and unpleasant odors (61.2%). Incineration operations disturb hospital residents (52.8%), according to the householders of the residents. During observation, we note deposits of waste that have not been destroyed and wastewater flowing in some places. Conclusion: Biomedical waste in Togo’s university hospitals generates environmental effects and therefore potentially high risks for human health. Improving their management should be a concern for all hospital actors.展开更多

Job satisfaction,safety and ensuring career progression are important in retaining doctors to make a career in Republic of South Africa (RSA). Due to budgetary constraints many hospitals have not been upgraded. Coming home after overseas training seems difficult. In RSA it takes a minimum of 13 years for a young specialist to become registered and 15 years for subspecialists. Career progression,creating more specialist trainees in public and private hospitals and shortening the period of professional training are potential solutions to the problem. India,which has a population of more than 1 billion people,is struggling with similar problems. For the past 10-15 years,private hospitals have assisted in manpower development for medical specialist and subspecialist careers. Currently their private sector trains 60% of their recognised (sub)specialities fellows. A national task force for specialist training in RSA should be instituted. It should discuss,based on the current status and projected specialist and subspecialist personnel requirements,thefuture structure and logistics of training needs. This is required in all subspecialities including gastroenterology,as has been done in India. It is hoped that as a consequence well-trained doctors,similar to those in India,might move to provincial hospitals in rural areas,upgrading the medical services and keeping medical power in South Africa. South Africa should become a model for Sub-Saharan Africa,as India already is for South-East Asia.展开更多

The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.展开更多

Individual case records were reviewed with regard to history, clinical, findings from colonoscopy, biopsies, small bowel enema, computerized tomography scan, treatment and outcome.RESULTS: Seventy-seven patients with Crohn's disease were revisited, 13% presented the disease in the first 10 years and 87% over the last 10 years. Thirty-three patients (42.9%) were males and 44 (57.1%) were females. Age ranged from 11-70 years (mean of 25.3+11.3 years). Ninety-two (92%) were Saudi. The mean duration of symptoms was 26+34.7 mo. The mean annual incidence of the disease over the first 10 years was 0.32:100 000 and 1.66:100 000 over the last 10 years with a total mean annual incidence of 0.94:100 000 over the last 20 years. The chief clinical features included abdominal pain, diarrhea, weight loss,anorexia, rectal bleeding and palpable mass. Colonoscopic findings were abnormal in 58 patients (76%) showing mostly ulcerations and inflammation of the colon. Eighty nine percent of patients showed nonspecific inflammation with chronic inflammatory cells and half of these patients revealed the presence of granulomas and granulations on bowel biopsies. Similarly, 69 (89%) of small bowel enema results revealed ulcerations (49%), narrowing of the bowel lumen (42%), mucosal thickening (35%) and cobblestone appearance (35%). CT scan showed abnormality in 68 (88%) of patients with features of thickened loops (66%) and lymphadenopathy (37%). Seventy-eight percent of patients had small and large bowel disease, 16% had small bowel involvement and only 6% had colitis alone. Of the total 55 (71%) patients treated with steroids at some point in their disease history, a satisfactory response to therapy was seen in 28 patients (51%) while 27 (49%) showed recurrences of the condition with mild to moderate symptoms of abdominal pain and diarrhea most of which were due to poor compliance to medication. Seven patients (33%) remained with active Crohn's disease. Nine (12%) patients underwent surgery with resections of some parts of bowel, 2 (2.5%) had steroid side effects, 6 (8%) with perianal Crohn's disease and five (6.5%) with fistulae.CONCLUSION: The epidemiological characteristics of Crohn's disease among Saudi patients are comparable to those reported from other parts of the world. However the incidence of Crohn's disease in our hospital increased over the last 10 years. The anatomic distribution of the disease is different from other world institutions with less isolated colonic affection.展开更多

It is an acute, rare pathology, its incidence is estimated at 1 to 2 cases out of one million inhabitants per year and its evolution can be fatal. Materials and Methods: We report the observation of a 60-year-old patient, with no significant pathological history, admitted to our intensive care unit at the Renaissance University Teaching Hospital in N’Djamena for the treatment of Toxic Epidermal Necrolysis. In whom the onset of symptoms dates back to few hours after vaccination against COVID-19 with Ag Johnson and Johnson. Results: An ophthalmology opinion was requested and the patient was put on Fucithalmic. In our case, in addition to the advanced age of the patient (60 years old), her SCORTEN was ≥5. Conclusion: The late management as well as the absence of a specific department for severe burns, which condition the presence of a technical plate was fatal to her despite multidisciplinary care: Resuscitators, Traumato-Orthopedist and ophthalmologist.展开更多

The objectives of this study were to determine the frequency of TMJA, describe the clinical aspects and assess management. <strong>Materials and Method:</strong> It was a retrospective study that was carried out in the Department of Odontostomatology and Maxillofacial Surgery of Donka National Hospital for a period of 5 years (January 2016 to December 2020). Included were all records of inpatients and managed cases of TMJA during the study period. Socio-demographic, clinical and therapeutic variables were analyzed. <strong>Results:</strong> During the study 13 TMJA cases were collected with the frequency of 0.47%. The age group 1 - 9 was the most affected (61.54%) with extremes of 4 and 28 years. Men were the most concerned (53.87%). Restriction of mouth opening was the main reason for consultation (69.23%). The etiologies of ankylosis were dominated by infection including cellulitis of dental origin (53.85%) followed by facial trauma (30.77%). Arthroplasty was the most commonly used technique (73%), two cases of recurrence were noted (15.38%). <strong>Conclusion: </strong>TMJA affects mainly children and the etiology is dominated by cellulite of dental origin hence the interest of sensitization of the population for early management of oral diseases.展开更多

The aim of our study was to study hydro-electrolyte disorders in brain-damaged patients, to describe the clinical aspects, to identify the contributing factors and to determine the prognosis of these patients in the intensive care unit of gabriel touré teaching hospital. <strong>Material and Methods:</strong> It was a prospective cross-sectional study, descriptive of a period of 11 months going from June 2015 to April 2016 in the intensive care unit of CHU Gabriel TOURE we included all the cerebral patients admitted in intensive care in which hydro-ionic disorders have detected on arrival or during hospitalization. Data were collected through transfer sheets, a survey sheet and medical records. Data entry and analysis were done respectively on SPSS software (version 19) and Microsoft Word Starter 2010 software. <strong>Results:</strong> During our study, out of 450 hospitalization patients, we identified 110 brain-damaged patients and 75 patients were retained in our study, i.e. a prevalence of 16.6%. Male was predominant with 72% with a sex ratio of 2.5 the age group 20 - 50 years was majority with 45.3%, the average age was 38.49 years. The majority of patients (58.7%) were admitted from the emergency department. The most common reason for admission was impairment of consciousness in 94.7% (Table 1) of cases and the Glasgow admission score was less than or equal to 8 in 58.7% (Table 1) of patients. Hydro-electrolyte disturbances were present in 93.3% of patients on admission. Hyponatremia was the most common disorder with 56% (42 cases). Followed by hyperkalaemia 10.7% (8 cases), hypernatremia 9.3% (7 cases), at hypocalcemia 9.3% (7 cases), associated disorders 8% (6 cases). Brain CT was performed in 52% of the patients. In our study, malaria was the most common etiology of ionic disorders with 36%. Of the patients who died, 80% had developed hyponatremia after 5 days in hospital, and the overall lethality was 73.3%. <strong>Conclusion:</strong> Hydro-electrolyte disorders are frequent in the intensive care setting and their management must be rapid in order to reduce morbidity and mortality.展开更多

It is an immunological disease and certain environmental factors, in particular viral infections and allergens, influence its occurrence. The climatic and environmental differences coupled with the frequency of infectious pathologies signing the African particularity and the absence of data in Mali on this affection, motivated us to carry out this work. Objective: To study the epidemiological aspects of nephrotic syndrome in hospitalized children aged 0 - 15 years. Patients and Methods: This was a descriptive prospective study from January 1 to December 31, 2021 in the Pediatrics Department of the University Teaching Hospital (UTH) Gabriel Touré, anational pediatric reference service in Mali. Diagnostic confirmation was provided by biology. Results: In one year, 120 children were hospitalized for nephrotic syndrome with a sex ratio of 2.75. Male exclusivity was observed at the ages of one year, eight years and 14 years and a reversal at 13 years (sex-ratio = 0.33). The median age was 6 years for an average age of 6.4 years ± 2.4 years with extremes ranging from one year to 14 years. The first attack of nephrotic syndrome occurred outside the classic age (>10 years) in 16.67%. Nephrotic syndrome is observed throughout the year with two peaks in summer (July to September) and winter (December to February). Many ethnic groups were affected by this condition with a high frequency among ethnic groups where endogamy is common. All patients were melanoderms. No cases of NS were recorded in Caucasian children from Northern Mali. The patients came from Bamako in 47.5% of cases. Two brothers from the same siblings had had their first attack of nephrotic syndrome the same year, ten months apart. Conclusion: Nephrotic syndrome in pediatric hospitals of Bamako occurs at a median age of six years all along the year with a summer and winter peaks. It is more observed in ethnic groups where the practice of endogamy is common and concerns melanoderm children.展开更多

Objective: The purpose of this study was to assess non-Hodgkin lymphomas cases in our setting. Methodology: A retrospective and descriptive study carried out in the pediatric oncology unit of the Gabriel Touré Teaching Hospital Bamako over 10 years from 1st January 2005 to 31th December 2015. Results: We exploited 274 (21.6%) cases of Non-Hodgkin Lymphoma out of 1295 cancer cases registered, the age group 6 - 10 years was the most represented (46.4%);the male sex was predominant with a sex-ratio of 1.8;digestive signs were the most common signs of discovery (44.2%) followed by maxillary swelling (42.7%);the majority of patients (52.9%) consulted between 1 and 3 months after the onset of signs;the malnutrition rate was 39.8%, of which 24.1% were severe cases and 15.7% were moderate rate. Abdominal localization was the most common (43.1%) followed by maxillofacial localization (33.9%). Almost all were Burkitt type cytology (92.7%), the majority (73.4%) were in Murphy stage III. Almost all (96%) had received chemotherapy and the modified LMB 01 protocol was widely used (62.4%). The majority of patients (85%) were chemosensitive at day 7 or after the third cyclophosphamide injection but at the end of induction only 31% were in complete remission. Gastrointestinal toxicity was the most common (37.13%) followed by hematologic toxicity 35.09 %;9.12 % of patients were lost of follow-up and 22.26% died. Tumor progression was the most common cause of death (60.66%) followed by infection (21.31%). Conclusion: In light of these findings, the late diagnosis and the poor management of NHL, as well as the limited ability to primarily treat metabolic complications, explain the high case-fatality rate, hence the important role of early diagnosis and treatment multidisciplinary.展开更多

As part of efforts to combat AMR, the World Health Organization has identified Antimicrobial Stewardship as one of the strategic objectives of its global action plan on antimicrobial resistance. This survey aimed to observe antimicrobial prescribing and usage patterns in the Rivers State University Teaching Hospital with the purpose of identifying gaps to inform the specific antimicrobial stewardship interventions necessary to address our specific needs. Methodology: A point prevalence survey was conducted using the protocol and web-based automated data management system designed by the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance, University of Antwerp, Belgium, in November 2021. Results: A total of 69 adult medical and surgical patients were surveyed;27 males and 18 females. Antimicrobial prevalence was 65.2%. Third generation cephalosporins (24.4%;33.3%), fluoroquinolones (17.8%;22.2%) and imidazole derivatives (20%;36.1%) were most prescribed on the medical and surgical wards. Antimicrobial guidelines were completely unavailable, most antimicrobials (93.8%) were prescribed empirically and 64.4% of these remained empirical after 72 hours of commencement. Conclusion: Antimicrobial stewardship interventions are necessary to minimize sub-optimal antimicrobial prescribing practices in our facility. Most critical are education on appropriate use of antimicrobials, support for development of antimicrobial guidelines, diagnostic stewardship, and the drive for improved use of the laboratory to guide antimicrobial prescriptions. The antimicrobial stewardship committee and team must drive this, having the requisite support from the management and prescribers, with the primary outcomes being reduced antimicrobial prevalence and improved antimicrobial prescription patterns.展开更多

The initial clinical picture was peritonitis in 26 cases or 49.1%, occlusion in 16 cases or 30.2% and tumors in 6 cases or 11.3%. The post-operative complications responsible for evisceration were: parietal suppuration 28 cases or 52.8%;digestive fistulas 15 cases or 28.3%;post-operative ascites 4 cases or 7.5%. <strong>Conclusion:</strong> Post-operative acute evisceration is a rare but serious condition due to morbidity and mortality.
文摘Objective:Despite trials and programs for the prevention of childhood mortality due to pneumonia,Ethiopia is among the top five countries with the highest number of deaths due to pneumonia.Although the prevalence of pneumonia has increased in the abovementioned trials,little is known about the recovery time from severe pneumonia and its predictors in the study area.Therefore,this study aimed to assess the time to recovery from severe pneumonia and its predictors among pediatric patients admitted to Mizan-Tepi University Teaching Hospital,Ethiopia,in 2022.Methods:A total of 591 children admitted for severe pneumonia were selected using simple random sampling.Data were entered into Epi-data version 4.4.2.1 and expor ted to STATA version 14 for analysis,and the assumptions of Cox propor tional hazard models and goodness of fit were assessed through Shoenfeld residual and Cox-Snell residual,respectively.Bivariate and multivariable Cox regression models were used to identify the predictors of mor tality.Results:This study revealed that 91.54%(95%confidence interval[CI]:89.00–93.53)of participants recovered with an incidence rate of 24.10(95%CI:22.15–26.21)per 100 person-day–observations.The hmedian recovery time of children was 4 days(95%CI:2–6).Children who were not exclusively breastfed(AHR=1.3;95%CI:1.03–1.66),who had a history of inability to suck/feed(AHR=0.81;95%CI:0.65–0.99)were independent predictors of the time to recovery.Conclusions:Children with severe pneumonia who had not exclusively breastfed and who had a history of inability to suck/feed were independent predictors of time to recovery.Therefore,all stakeholders and concerned health care providers should focus more on early diagnosis and management and hasten early recovery based on the identified factors.
文摘Introduction: Given its effects, hospital waste is an environmental concern and a threat to health personnel, users of health services and neighboring populations. Our objective was to assess the perception of health care stakeholders on the environmental effects related to biomedical waste produced in Teaching Hospitals (CHU) in Togo in 2021. Methods: This was a cross-sectional study held from June 24 to August 28, 2021. It targeted three university hospitals, 340 health care providers and services selected by a probabilistic method with a simple random technique in 25 services, 72 directors, deputy directors, supervisors and heads of services, 27 collection and incineration agents selected by a non-probabilistic method with a reasoned choice technique, 44 patients and attendants and 36 householders of neighboring residents selected by a non-probabilistic method with an accidental choice technique. Variables such as the spreading of disease vectors, soil, air and water contamination, the presence of unpleasant odors and unsightly living conditions were assessed. Results: According to the respondents, biomedical waste causes the proliferation of vectors (55.3%), an unsightly environment inside the hospital (47.1%), and unpleasant odors (61.2%). Incineration operations disturb hospital residents (52.8%), according to the householders of the residents. During observation, we note deposits of waste that have not been destroyed and wastewater flowing in some places. Conclusion: Biomedical waste in Togo’s university hospitals generates environmental effects and therefore potentially high risks for human health. Improving their management should be a concern for all hospital actors.
文摘BACKGROUND:Studies looking at the effect of hospital teaching status on septic shock related in-hospital mortality are lacking.The aim of this study was to examine the effect of hospital teaching status on mortality in septic shock patients in the United States.METHODS:This was a retrospective observational study,using the Nationwide Emergency Department Sample Database(released in 2018).All patients with septic shock were included.Complex sample logistic regression was performed to assess the impact of hospital teaching status on patient mortality.RESULTS:A total of 388,552 septic shock patients were included in the study.The average age was 66.93 years and 51.7%were males.Most of the patients presented to metropolitan teaching hospitals(68.2%)and 31.8%presented to metropolitan non-teaching hospitals.Septic shock patients presenting to teaching hospitals were found to have a higher percentage of medical comorbidities,were more likely to be intubated and placed on mechanical ventilation(50.5%vs.46.9%)and had a longer average length of hospital stay(12.47 d vs.10.20 d).Septic shock patients presenting to teaching hospitals had greater odds of in-hospital mortality compared to those presenting to metropolitan non-teaching hospitals(adjusted odd ratio[OR]=1.295,95%confidence interval[CI]:1.256-1.335).CONCLUSION:Septic shock patients presenting to metropolitan teaching hospitals had significantly higher risks of mortality than those presenting to metropolitan non-teaching hospitals.They also had higher rates of intubation and mechanical ventilation as well as longer lengths of hospital stay than those in non-teaching hospitals.
文摘In South Africa,nurses and doctors are emigrating in significant numbers. Job satisfaction,safety and ensuring career progression are important in retaining doctors to make a career in Republic of South Africa (RSA). Due to budgetary constraints many hospitals have not been upgraded. Coming home after overseas training seems difficult. In RSA it takes a minimum of 13 years for a young specialist to become registered and 15 years for subspecialists. Career progression,creating more specialist trainees in public and private hospitals and shortening the period of professional training are potential solutions to the problem. India,which has a population of more than 1 billion people,is struggling with similar problems. For the past 10-15 years,private hospitals have assisted in manpower development for medical specialist and subspecialist careers. Currently their private sector trains 60% of their recognised (sub)specialities fellows. A national task force for specialist training in RSA should be instituted. It should discuss,based on the current status and projected specialist and subspecialist personnel requirements,thefuture structure and logistics of training needs. This is required in all subspecialities including gastroenterology,as has been done in India. It is hoped that as a consequence well-trained doctors,similar to those in India,might move to provincial hospitals in rural areas,upgrading the medical services and keeping medical power in South Africa. South Africa should become a model for Sub-Saharan Africa,as India already is for South-East Asia.
文摘Gestational diabetes mellitus is the most common endocrine disorder in pregnancy and a cause of maternal and fetal morbidities and mortalities. The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.
文摘AIM: To know the epidemiology and outcome of Crohn's disease at King Khalid University Hospital, Riyadh, Saudi Arabia and to compare the results from other world institutions.METHODS: A retrospective analysis of patients seen for 20 years (between 1983 and 2002). Individual case records were reviewed with regard to history, clinical, findings from colonoscopy, biopsies, small bowel enema, computerized tomography scan, treatment and outcome.RESULTS: Seventy-seven patients with Crohn's disease were revisited, 13% presented the disease in the first 10 years and 87% over the last 10 years. Thirty-three patients (42.9%) were males and 44 (57.1%) were females. Age ranged from 11-70 years (mean of 25.3+11.3 years). Ninety-two (92%) were Saudi. The mean duration of symptoms was 26+34.7 mo. The mean annual incidence of the disease over the first 10 years was 0.32:100 000 and 1.66:100 000 over the last 10 years with a total mean annual incidence of 0.94:100 000 over the last 20 years. The chief clinical features included abdominal pain, diarrhea, weight loss,anorexia, rectal bleeding and palpable mass. Colonoscopic findings were abnormal in 58 patients (76%) showing mostly ulcerations and inflammation of the colon. Eighty nine percent of patients showed nonspecific inflammation with chronic inflammatory cells and half of these patients revealed the presence of granulomas and granulations on bowel biopsies. Similarly, 69 (89%) of small bowel enema results revealed ulcerations (49%), narrowing of the bowel lumen (42%), mucosal thickening (35%) and cobblestone appearance (35%). CT scan showed abnormality in 68 (88%) of patients with features of thickened loops (66%) and lymphadenopathy (37%). Seventy-eight percent of patients had small and large bowel disease, 16% had small bowel involvement and only 6% had colitis alone. Of the total 55 (71%) patients treated with steroids at some point in their disease history, a satisfactory response to therapy was seen in 28 patients (51%) while 27 (49%) showed recurrences of the condition with mild to moderate symptoms of abdominal pain and diarrhea most of which were due to poor compliance to medication. Seven patients (33%) remained with active Crohn's disease. Nine (12%) patients underwent surgery with resections of some parts of bowel, 2 (2.5%) had steroid side effects, 6 (8%) with perianal Crohn's disease and five (6.5%) with fistulae.CONCLUSION: The epidemiological characteristics of Crohn's disease among Saudi patients are comparable to those reported from other parts of the world. However the incidence of Crohn's disease in our hospital increased over the last 10 years. The anatomic distribution of the disease is different from other world institutions with less isolated colonic affection.
文摘BACKGROUND Acute variceal bleeding is a major complication of portal hypertension and is a leading cause of death in patients with cirrhosis.There is limited data on the outcomes of patients with esophageal variceal bleeding in teaching versus nonteaching hospitals.Because esophageal variceal bleeding requires complex management,it may be hypothesized that teaching hospitals have lower mortality.AIM To assess the differences in mortality,hospital length of stay(LOS)and cost of admission for patients admitted for variceal bleed in teaching versus nonteaching hospitals across the US.METHODS The National Inpatient Sample is the largest all-payer inpatient database consisting of approximately 20%of all inpatient admissions to nonfederal hospitals in the United States.We collected data from the years 2008 to 2014.Cases of variceal bleeding were identified using the International Classification of Diseases,Ninth Edition,Clinical Modification codes.Differences in mortality,LOS and cost were evaluated for patients with esophageal variceal bleed between teaching and nonteaching hospitals and adjusted for patient characteristics and comorbidities.RESULTS Between 2008 and 2014,there were 58362 cases of esophageal variceal bleeding identified.Compared with teaching hospitals,mortality was lower in nonteaching hospitals(8.0%vs 5.3%,P<0.001).Median LOS was shorter in nonteaching hospitals as compared to teaching hospitals(4 d vs 5 d,P<0.001).A higher proportion of non-white patients were managed in teaching hospitals.As far as procedures in nonteaching vs teaching hospitals,portosystemic shunt insertion(3.1%vs 6.9%,P<0.001)and balloon tamponade(0.6%vs 1.2%)were done more often in teaching hospitals while blood transfusions(64.2%vs 59.9%,P=0.001)were given more in nonteaching hospitals.Using binary logistic regression models and adjusting for baseline patient demographics and comorbid conditions the mortality,LOS and cost in teaching hospitals remained higher.CONCLUSION In patients admitted for esophageal variceal bleeding,mortality,length of stay and cost were higher in teaching hospitals versus nonteaching hospitals when controlling for other confounding factors.
文摘Purpose:This study sought to examine the anxiety and perception of nurses toward the outbreak of COVID‑19 in University of Uyo Teaching Hospital(UUTH).Two research questions one hypothesis were used.What is the level of anxiety among nurses toward the outbreak of COVID‑19?What is the perception of nurses toward the outbreak of COVID‑19?The hypothesis states that there is no significant relationship between anxiety and perception of nurses toward the outbreak of COVID‑19.Literature was reviewed based on the research variables.Methods:The research instrument used in collecting the data for the analysis was a questionnaire administered to 100 nurses in UUTH,Uyo.Their responses were analyzed using frequencies,percentages,and Chi‑square analysis,and the following results were obtained.Results:The results indicated that 36(36%)of the respondents strongly agreed that most nurses perceive that poor provision of equipment’s in the hospital result into the transmission of COVID‑19 to another person,35(35%)agreed,20(20%)of the respondents strongly agreed,whereas 9(9%)of the respondents disagreed.Majority of the respondents 56(56%)strongly agreed that nurses sometimes perceive that patients sometimes harbor COVID‑19 without showing the symptoms.Conclusion:The above data,therefore,showed that nurses in UUTH,Uyo,had moderate perception toward COVID‑19.
文摘Introduction: Lyell’s syndrome (SL), called Toxic Epidermal Necrolysis is one of the most serious forms of medication accidents. It is an acute, rare pathology, its incidence is estimated at 1 to 2 cases out of one million inhabitants per year and its evolution can be fatal. Materials and Methods: We report the observation of a 60-year-old patient, with no significant pathological history, admitted to our intensive care unit at the Renaissance University Teaching Hospital in N’Djamena for the treatment of Toxic Epidermal Necrolysis. In whom the onset of symptoms dates back to few hours after vaccination against COVID-19 with Ag Johnson and Johnson. Results: An ophthalmology opinion was requested and the patient was put on Fucithalmic. In our case, in addition to the advanced age of the patient (60 years old), her SCORTEN was ≥5. Conclusion: The late management as well as the absence of a specific department for severe burns, which condition the presence of a technical plate was fatal to her despite multidisciplinary care: Resuscitators, Traumato-Orthopedist and ophthalmologist.
文摘<strong>Introduction: </strong>Temporomandibular joint ankylosis (TMJA) is a fusion of joint surfaces by fibrous or bone tissue and the resulting limitation of mouth opening. The objectives of this study were to determine the frequency of TMJA, describe the clinical aspects and assess management. <strong>Materials and Method:</strong> It was a retrospective study that was carried out in the Department of Odontostomatology and Maxillofacial Surgery of Donka National Hospital for a period of 5 years (January 2016 to December 2020). Included were all records of inpatients and managed cases of TMJA during the study period. Socio-demographic, clinical and therapeutic variables were analyzed. <strong>Results:</strong> During the study 13 TMJA cases were collected with the frequency of 0.47%. The age group 1 - 9 was the most affected (61.54%) with extremes of 4 and 28 years. Men were the most concerned (53.87%). Restriction of mouth opening was the main reason for consultation (69.23%). The etiologies of ankylosis were dominated by infection including cellulitis of dental origin (53.85%) followed by facial trauma (30.77%). Arthroplasty was the most commonly used technique (73%), two cases of recurrence were noted (15.38%). <strong>Conclusion: </strong>TMJA affects mainly children and the etiology is dominated by cellulite of dental origin hence the interest of sensitization of the population for early management of oral diseases.
文摘A cerebrole is a patient with a neurological deficit of central origin;these patients very often present disorders of the ion concentration, hence the need for hospitalization in intensive care. The aim of our study was to study hydro-electrolyte disorders in brain-damaged patients, to describe the clinical aspects, to identify the contributing factors and to determine the prognosis of these patients in the intensive care unit of gabriel touré teaching hospital. <strong>Material and Methods:</strong> It was a prospective cross-sectional study, descriptive of a period of 11 months going from June 2015 to April 2016 in the intensive care unit of CHU Gabriel TOURE we included all the cerebral patients admitted in intensive care in which hydro-ionic disorders have detected on arrival or during hospitalization. Data were collected through transfer sheets, a survey sheet and medical records. Data entry and analysis were done respectively on SPSS software (version 19) and Microsoft Word Starter 2010 software. <strong>Results:</strong> During our study, out of 450 hospitalization patients, we identified 110 brain-damaged patients and 75 patients were retained in our study, i.e. a prevalence of 16.6%. Male was predominant with 72% with a sex ratio of 2.5 the age group 20 - 50 years was majority with 45.3%, the average age was 38.49 years. The majority of patients (58.7%) were admitted from the emergency department. The most common reason for admission was impairment of consciousness in 94.7% (Table 1) of cases and the Glasgow admission score was less than or equal to 8 in 58.7% (Table 1) of patients. Hydro-electrolyte disturbances were present in 93.3% of patients on admission. Hyponatremia was the most common disorder with 56% (42 cases). Followed by hyperkalaemia 10.7% (8 cases), hypernatremia 9.3% (7 cases), at hypocalcemia 9.3% (7 cases), associated disorders 8% (6 cases). Brain CT was performed in 52% of the patients. In our study, malaria was the most common etiology of ionic disorders with 36%. Of the patients who died, 80% had developed hyponatremia after 5 days in hospital, and the overall lethality was 73.3%. <strong>Conclusion:</strong> Hydro-electrolyte disorders are frequent in the intensive care setting and their management must be rapid in order to reduce morbidity and mortality.
文摘Introduction: The most frequent glomerular pathology in children, nephrotic syndrome (NS) is a cosmopolitan affection. It is an immunological disease and certain environmental factors, in particular viral infections and allergens, influence its occurrence. The climatic and environmental differences coupled with the frequency of infectious pathologies signing the African particularity and the absence of data in Mali on this affection, motivated us to carry out this work. Objective: To study the epidemiological aspects of nephrotic syndrome in hospitalized children aged 0 - 15 years. Patients and Methods: This was a descriptive prospective study from January 1 to December 31, 2021 in the Pediatrics Department of the University Teaching Hospital (UTH) Gabriel Touré, anational pediatric reference service in Mali. Diagnostic confirmation was provided by biology. Results: In one year, 120 children were hospitalized for nephrotic syndrome with a sex ratio of 2.75. Male exclusivity was observed at the ages of one year, eight years and 14 years and a reversal at 13 years (sex-ratio = 0.33). The median age was 6 years for an average age of 6.4 years ± 2.4 years with extremes ranging from one year to 14 years. The first attack of nephrotic syndrome occurred outside the classic age (>10 years) in 16.67%. Nephrotic syndrome is observed throughout the year with two peaks in summer (July to September) and winter (December to February). Many ethnic groups were affected by this condition with a high frequency among ethnic groups where endogamy is common. All patients were melanoderms. No cases of NS were recorded in Caucasian children from Northern Mali. The patients came from Bamako in 47.5% of cases. Two brothers from the same siblings had had their first attack of nephrotic syndrome the same year, ten months apart. Conclusion: Nephrotic syndrome in pediatric hospitals of Bamako occurs at a median age of six years all along the year with a summer and winter peaks. It is more observed in ethnic groups where the practice of endogamy is common and concerns melanoderm children.
文摘Background :Non-Hodgkin lymphomas are the first childhood cancer in sub-Saharan Africa. Objective: The purpose of this study was to assess non-Hodgkin lymphomas cases in our setting. Methodology: A retrospective and descriptive study carried out in the pediatric oncology unit of the Gabriel Touré Teaching Hospital Bamako over 10 years from 1st January 2005 to 31th December 2015. Results: We exploited 274 (21.6%) cases of Non-Hodgkin Lymphoma out of 1295 cancer cases registered, the age group 6 - 10 years was the most represented (46.4%);the male sex was predominant with a sex-ratio of 1.8;digestive signs were the most common signs of discovery (44.2%) followed by maxillary swelling (42.7%);the majority of patients (52.9%) consulted between 1 and 3 months after the onset of signs;the malnutrition rate was 39.8%, of which 24.1% were severe cases and 15.7% were moderate rate. Abdominal localization was the most common (43.1%) followed by maxillofacial localization (33.9%). Almost all were Burkitt type cytology (92.7%), the majority (73.4%) were in Murphy stage III. Almost all (96%) had received chemotherapy and the modified LMB 01 protocol was widely used (62.4%). The majority of patients (85%) were chemosensitive at day 7 or after the third cyclophosphamide injection but at the end of induction only 31% were in complete remission. Gastrointestinal toxicity was the most common (37.13%) followed by hematologic toxicity 35.09 %;9.12 % of patients were lost of follow-up and 22.26% died. Tumor progression was the most common cause of death (60.66%) followed by infection (21.31%). Conclusion: In light of these findings, the late diagnosis and the poor management of NHL, as well as the limited ability to primarily treat metabolic complications, explain the high case-fatality rate, hence the important role of early diagnosis and treatment multidisciplinary.
文摘Background: Antimicrobial resistance (AMR) is one of the top 10 global public health threats facing humanity and this burden is borne largely by low and middle-income countries. As part of efforts to combat AMR, the World Health Organization has identified Antimicrobial Stewardship as one of the strategic objectives of its global action plan on antimicrobial resistance. This survey aimed to observe antimicrobial prescribing and usage patterns in the Rivers State University Teaching Hospital with the purpose of identifying gaps to inform the specific antimicrobial stewardship interventions necessary to address our specific needs. Methodology: A point prevalence survey was conducted using the protocol and web-based automated data management system designed by the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance, University of Antwerp, Belgium, in November 2021. Results: A total of 69 adult medical and surgical patients were surveyed;27 males and 18 females. Antimicrobial prevalence was 65.2%. Third generation cephalosporins (24.4%;33.3%), fluoroquinolones (17.8%;22.2%) and imidazole derivatives (20%;36.1%) were most prescribed on the medical and surgical wards. Antimicrobial guidelines were completely unavailable, most antimicrobials (93.8%) were prescribed empirically and 64.4% of these remained empirical after 72 hours of commencement. Conclusion: Antimicrobial stewardship interventions are necessary to minimize sub-optimal antimicrobial prescribing practices in our facility. Most critical are education on appropriate use of antimicrobials, support for development of antimicrobial guidelines, diagnostic stewardship, and the drive for improved use of the laboratory to guide antimicrobial prescriptions. The antimicrobial stewardship committee and team must drive this, having the requisite support from the management and prescribers, with the primary outcomes being reduced antimicrobial prevalence and improved antimicrobial prescription patterns.
