Traumatismes abdominaux graves aux urgences du «Trauma Center¼ de Libreville: Aspects épidémiologiques, diagnostiques et évolutifs / Severe abdominal trauma in the emergency room of the Trauma Center Libreville: Epidemiological, diagnostic and evolutionary aspects

Les traumatismes abdominaux représentent environ 15-20 % des lésions observées en traumatologie. L'objectif est de décrire les aspects épidémiologiques, diagnostiques et évolutifs des traumatismes abdominaux graves admis aux urgences du Centre Hospitalier Universitaire d'Owendo (CHUO) au Gabon. Méthodes : Il s'agit d'une étude rétrospective transversale et descriptive. Elle s'est déroulée sur une période de vingt quatre mois de 2020 à 2021 aux urgences du CHUO. Seuls les patients présentant une pathologie abdominale traumatique classée grave ont été inclus. Les variables de l'étude étaient : l'âge, le genre, le mécanisme du traumatisme, la prise en charge pré hospitalière, les signes cliniques, le bilan paraclinique réalisé, le traitement chirurgical et l'évolution. Les données ont été analysées par le logiciel Microsoft Excel© Pro version 2019. Résultats : durant cette période, 4,6% (n=105) des patients présentaient un traumatisme abdominal dont 66,7% (n=70) avaient un traumatisme abdominal grave. L'âge moyen des patients était de 29,8 + 13,8 ans. Dans 70% des cas (n=49), les accidents de la voie publique étaient le principal mécanisme étiologique, puis secondairement les agressions avec 11,4% des cas. En per opératoire, les lésions spléniques représentaient 60% (n=42) des cas. La mortalité brute était de 20% (n=14). Les décès étaient survenus chez 64,2% de patients au cours des quarante-huit premières heures. Conclusion : A Libreville, les accidents de la voie publique représentent le principal pourvoyeur des traumatismes abdominaux graves. Ces urgences restent encore responsables d'une forte mortalité au Gabon

Value of dynamic subtraction MRI in assessing HCC response to image-guided loco-regional therapy

Background: Hepatocellular carcinoma (HCC) is considered one of the foremost cancers worldwide. Although the hepatic resection of HCC has a high existence in the clinical scenarios, locoregional management is preferred owing to the preservation of hepatic parenchyma with lower morbidity and mortality. Dynamic contrast-enhanced MR with subtraction imaging improves the evaluation of managed HCC with easy detection of residual or recurrent viable lesions. Patients and methods: This study was designed in a retrospective pattern from December 2020 to December 2022. Forty patients were referred to our radiology department with solitary HCC, underwent therapeutic intervention, then underwent follow-up by dynamic MRI study. Results: Forty patients with solitary HCC were conducted during our study; all underwent locoregional therapy with follow-up by dynamic MRI with subtraction technique one month later. The subtraction image has a sensitivity of 100%, specificity of 100%, PPV of 100%, NPV of 100%, and 100% accuracy, compared to 90.91%, 77.78%, 83.33%, 87.5%, and 85% for conventional dynamic images, 45.45%, 100%, 100%, 60% and 70% for diffusion-weighted images. Analysis of those results exhibited a considerable additive value of the subtraction technique to the dynamic MRI to detect the response of HCC after management. Conclusions: Subtraction MRI is a pivotal tool to assess the interventional treatment of HCC, particularly in lesions having pre-contrast high signal intensity with distinguished radiologists' confidence

Sonographic correlations between intravesical prostatic protrusion and bladder outlet obstruction in patients with symptomatic benign prostatic hyperplasia in Ibadan, Nigeria

Evaluating bladder outlet obstruction (BOO) in patients with prostatic enlargement may reflect the severity of the disease and aid in predicting the treatment outcome. Objectives: To determine the sonological correlation between intravesical prostatic protrusion and bladder outlet obstruction in patients with symptomatic benign prostatic enlargement. Methods: This prospective study was conducted over one year at the Department of Radiology, University College Hospital, Ibadan. A transabdominal ultrasound scan of the urinary bladder and prostate gland was carried out on patients with prostatic enlargement and BOO. The intravesical prostatic protrusion, pre-and post-void urine volumes, prostate volume and bladder wall thickness were measured. Results: A total of 132 men aged 43 to 90 years (mean age: 63.8±8.64 years) were studied. The median size of the intravesical prostatic protrusion (IPP) was 7.25 mm (IQR: 0.00 mm; 14.9 mm). The mean prostate volume was 63.3ml±36.0ml. Most subjects (55; 41.7%) had a prostate volume above 60ml, and most patients (101, 77.2%) had bladder wall thickness less than 5mm. The mean bladder wall thickness was 4.26mm±1.54mm. There was a statistically significant correlation between IPP and pre-void urine volume and prostate volume (p = 0.002 and <0.001, respectively). Patients over 70 years had increasing IPP and post-void urine, which lacked statistical significance (p =0.15). Conclusion: The severity of bladder outlet obstruction was reflected in the pre-void urine volume, which correlated with the size of IPP

But : Evaluer les résultats initiaux de nos des différents traitements des fractures ouvertes de l'humérus. Méthode: Il s'agissait d'une étude rétrospective réalisée à Abidjan (Côte d'Ivoire) sur une période de 10 ans, portant sur 16 fractures ouvertes de la diaphyse humérale. Elle incluait 10 hommes et six femmes d'âge moyen de 32,8 ans (Extrêmes : 21 et 61). L'ouverture cutanée était classée selon Cauchoix et Duparc. Les fractures étaient, soit traitées par parage suivi de plâtre brachio-anti-brachial, soit traitées par plaque vissée ou fixateur externe. Les patients étaient suivis selon un protocole strict. Les résultats globaux étaient évalués par la cotation fonctionnelle de Stewart et Hundley. Résultats : Au recul minimum de 24 mois, tous les patients avaient consolidé. On notait un cas d'infection locale, trois cas de raideur du coude et quatre cas réversibles de paralysie du nerf radial. Les résultats fonctionnels selon le score de Stewart et Hundley étaient très bons dans 11 cas, bons dans quatre cas et assez-bon dans un cas, et aucun mauvais résultat. Conclusion : En fonction des indications thérapeutiques, les résultats initiaux sont satisfaisants tant sur le plan clinique que fonctionnel.

Aim: To evaluate the initial results of our different treatments of open humeral shaft fractures. Method: This was a retrospective study conductecd in Abidjan (Ivory Coast) over a period of 10 years, involving 16 open humeral shaft fractures. It included 10 men and six women with a mean age of 32.8 years (Extremes: 21 and 61). The skin opening was classified according to Cauchoix and Duparc. Fractures were either treated by trimming followed by a brachial-ante-brachial cast, or treated with a screwed plate or external fixator. Patients were followed according to a strict protocol. Overall results were assessed by Stewart and hundley functional scoring. Results: At a minimum follow-up of 24 months, all patients had consolidated. There was one case of local infection, three cases of elbow stiffness and four reversible cases of radial nerve palsy. The functional results according to the Stewart and Hundley score were very good in 11 cases, good in four cases and fair in one case, with no poor result. Conclusion: Depending on the therapeutic indications, the initial results are satisfactory both clinically and functionally.

Le taux de lymphocytes T CD4 au diagnostic de la séropositivité au virus de l'immunodéficience humaine à Libreville, 2022 / CD4 T lymphocyte count at diagnosis of human immunodeficiency virus seropositivity in Libreville, 2022

Introduction. L'efficacité du traitement antirétroviral dans la restauration immunitaire dépend fortement du stade de l'infection et du taux de lymphocyte TCD4 au moment de l'introduction du traitement. Nous avons évalué le taux de lymphocytes TCD4 à la découverte de la séropositivité au VIH pour caractériser le niveau d'infection de chaque patient. Matériel et méthodes. C'est une étude transversale et descriptive qui s'est déroulée dans le laboratoire de virologie de la faculté de médecine de Libreville. Nous avons analysé les données de la cohorte DERIRADO. Résultats. Nous avons inclus 133 patients. L'âge médian était de 45 ans (Q1-Q3 :37 ; 52). La médiane de LTCD4 était de 388 cellules/mm3 (Q1-Q3 : 250 ; 556). Le diagnostic était avancé chez 112 (84%) patients. Conclusion. La découverte de la séropositivité au Virus de l'Immunodéficience Humaine est faite à un stade d'immunodépression avancé chez la majorité des patients. Ce constat relève la nécessité de mettre en route les politiques de sensibilisation pour cibler les populations clés et amener le plus grand nombre au dépistage de l'infection par le Virus de l'Immunodéficience Humaine si l'on veut diminuer la courbe de transmission.

Introduction. The effectiveness of antiretroviral therapy in immune restoration largely depends on the stage of infection and the TCD4 lymphocyte count at the time of treatment initiation. We evaluated the rate of TCD4 lymphocytes at the discovery of HIV seropositivity to characterize the level of infection of each patient. Methods. This was a cross sectional descriptive and analytic study whose setting was the laboratory of virology of the faculty of medicine of Libreville. Our data source was DERIRADO cohort. Results. We included 133 patients. The median age was 45 (Q1- Q3:37;52). The median LTCD4 was 388 cells/mm3 (Q1-Q3: 250; 556). The diagnosis was advanced in 112 (84%) patients. Conclusion. The diagnosis of seropositivity to the Human Immunodeficiency Virus is made at a stage of immunosuppression in the majority of patients. This highlights the need to implement sensitization policies to target key populations and bring as many people as possible to screening in order to reduce the transmission curve

Treatment Outcomes in COVID-19 patients with comorbidities in Kaduna state, NorthwesternNigeria

Background: Severe COVID-19 disease has been reported among people with underlying conditions such as diabetes, chronic respiratory diseases, cancer, obesity, and cardiovascular disease. This study determined the outcomes of COVID-19 among patients with comorbidities in Kaduna state, where we have the highest incidence in northern Nigeria.Methods: This study was a retrospective, descriptive cross-sectional review of the clinical records involving all age groups of 902 COVID-19 patients admitted at the four isolation centers of the Kaduna State Infectious Disease Control Centre (IDCC) between March 27th2020 to December 31st2021. Data was analyzed with SPSS version 25 and STATA SE 12 with p <0.05.Results: Out of the 902 cases, 245(27.2%) had comorbidities, hypertension 206(22.8%) was the most recorded comorbidity, others were diabetes 77(8.5%), asthma 7 (0.78%), HIV 7(0.78%), sickle cell anemia 7 (0.78%) and PTB 3 (0.33%). Patients with comorbidities had prolonged mean duration of symptoms 8.36±3.5 days, compared to 7.2±2.7 days in those without comorbidities (p=0.001).Multivariate logistic regression analysis further shows that the odds for clinical recovery from the COVID-19 disease was significantly lower for patient with hypertension (AOR=0.13, 95%CI=0.06-0.27, p = <0.01), diabetic (AOR=0.20, 95% CI=0.10-0.40, p<0.01) and HIV comorbidities (AOR=0.1, 95%CI=0.01-0.98, p=0.05) compared to those without comorbiditiesConclusion: Hypertension and diabetes were the major comorbidities in this study. Most patients with comorbidities had severe presentations and fatal poorer outcome. There is a need for sustained public health education targeted at patients with chronic diseases to be screened and treated early for COVID 19 Disease

Management of unerupted anterior teeth: an audit of treatment outcomes

Introduction: Anterior teeth are valuable for aesthetics, speech and mastication. Their absence, impaction, and/or delayed eruption reate significant distress often leading to early presentation to the dental office. This study presents an audit of the management of impacted anterior teeth that presented at a tertiary level dental clinic. The periodontal outcomes of the aligned teeth were also reported. Methods: This is an observational study spanning a nine-year period. Demographic data, clinical presentation, as well as post alignment dental and periodontal status of the impacted teeth were assessed. Data were analysed using the Statistical Package for Social Sciences (SPSS) version 26. Fisher's exact test and paired samples T-test were used for categorical and continuous variables respectively. Significance was set at P < 0.05. Results: Twenty-eight (1.76%) cases presented with failed eruption of 32 anterior teeth were observed during the period under review. Eight patients were treated by extraction, orthodontic treatment, and space closure or prosthetic replacement, with a mean treatment time of 2.83 ± 2.66 years. Thirteen patients completed treatment by orthodontic alignment with mean alignment time of 1.4 ± 1.5 years and treatment time of 3.6 ± 2.5 years. Average loss of root length observed was 1.5mm. There was significant difference in the post-operative root length of aligned teeth compared to their normal antimeres (p < 0.005). Conclusion: Patients with impacted anterior teeth presented later than was beneficial for spontaneous alignment of their teeth. The average 1.5mm loss of root length observed was not detrimental to the anatomical retention or function of the aligned teeth. There is need for more enlightenment with regards to early presentation for dental problems to avoid expensive and time-consuming treatments.

A systematic review of clinical characteristics, co-morbidities and outcomes of COVID-19 in children and adolescents

Background: COVID-19 is a major global health challenge that has affected all age groups and gender, with over 5 million deaths reported worldwide to date. The objective of this study is to assess available information on COVID-19 in children and adolescents with respect to clinical characteristics, co-morbidities, and outcomes, and identify gaps in the literatures for appropriate actions. Methodology: Electronic databases including Web of Science, PubMed, Scopus, and Google Scholar were searched for observational studies such as case series, cross-sectional and cohort studies published from December 2019 to September 2021, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guide. Data extracted included (i) patient demography (age and gender), (ii) clinical characteristics including vaccination status and presence of co-morbidities, (iii) clinical management including the use of sequential organ failure assessment (SOFA) scores, oxygen requirement, use of mechanical ventilation, and (iv) disease outcomes including length of hospital and intensive care unit (ICU) admission, recovery, complications with sequelae, or death. Data were analyzed using descriptive statistics. Results: A total of 11 eligible studies were included with a total of 266 children and adolescents; 137 (51.5%) females and 129 (48.5%) males. The mean age of the children was 9.8 years (range of 0 ­ 19 years), and children ≥ 6 years were more affected (40.7%) than age groups 1 ­ 5 years (31.9%) and < 1 year (27.4%). The major co-morbidities were respiratory diseases including pre-existing asthma (3.4%), neurologic conditions (3.4%) and cardiac pathology (2.3%). Majority (74.8%, 199/266) of the patients were discharged without sequelae, 0.8% (2/266) were discharged with sequalae from one study, and mortality of 1.9% (5/266) was reported, also from one study. SOFA scores of patients at admission were not stated in any of the study, while only one study reported patient vaccination status. Conclusion: It is recommended that safe vaccines for children < 1 year of age should be developed in addition to other preventive measures currently in place. SOFA scores should be used to assess risk of COVID-19 severity and monitor prognosis of the disease, and vaccination status of children should be documented as this may impact the management and prognosis of the disease.

Outcomes of tuberculosis treatment in a tertiary health facility in north-central Nigeria

Background: Tuberculosis (TB) remains a major public health concern despite being a curable and preventable disease. The treatment of TB using a cocktail of drugs over a period of six months under the directly observed treatment short-course strategy has led to a reduction in cases but is plagued by some challenges that leads to unsuccessful or poor outcomes, which can ultimately result in spread of infections, development of drug resistance and increase in morbidity and mortality. The objectives of this study are to determine outcomes of TB treatment in Dalhatu Araf Specialist Hospital, Lafia, Nasarawa State, Nigeria and the factors that may be associated with the outcomes. Methodology: This was a retrospective study using the medical records of patients who were registered for TB treatment over a five-year period between 2016 to 2020. Data from TB registers including demographic and relevant clinical information, and treatment outcomes, were extracted into a structured data extraction format, and analysed with SPSS version 21.0 software package. Univariate and bivariate analyses were conducted, and Chi square test was used to determine association between TB outcomes and independent variables at 95% confidence interval and p<0.05 was considered as the significant value. Results: Records of 1,313 patients were studied, 744 (56.7%) were males while 569 (43.3%) were females. The age range of the patients was ≤ 1 year - 96 years, with a mean age of 30±16.7 years. Most were pulmonary TB cases (88.8%, n=1,166), newly diagnosed (95.5%, n=1254), and human immunodeficiency virus (HIV) negative at the time of TB diagnosis (63.7%, n=837). Eight hundred and seven (61.5%) patients had successful treatment, and 34% (n=446) had unsuccessful outcomes made of 'loss to follow-up' 25.8% (n=339), deaths 7.8% (n=102) and treatment failure 0.4% (n=5), while 2.3% (n=30) were transferred out and 2.3% (n=30) removed from TB register. Treatment success rate was significantly higher in patients with pulmonary TB (p=0.0024), residents in Lafia LGA (p=0.0005), those treated in 2016 (p=0.0006) and bacteriologically confirmed cases (p<0.0001), while death rate was significantly lower among patients who were HIV-negative at the time of TB diagnosis (p<0.0001). Conclusion: TB treatment success rate in this study fell short of the WHO average rate. High rates of 'loss to followup' and deaths in this study is a wake-up call to all stakeholders in the facility and the State to put in place measures to reduce poor outcomes of TB treatment.

Bitter kola and kola nut use and their effect on treatment outcome on People Living with HIV at a Military Hospital in Benue state Nigeria: Bitter kola (Garcinia) and Cola nut (Cola nitida among PLWHIV

Introduction Bitter Kola (Garcinia Kola) and kola nut, contains substances attributed to numerous effects on humans including anti-inflammatory, anti-allergic properties, anti-infective and caffeinism. This study explores Bitter kola and kola nut use and its impact on treatment outcome on People Living with HIV (PLWHIV). Methods: The study was conducted at a Military Hospital in Nigeria. An analytical cross-sectional study was done using questionnaire among 700 HIV-positive clients selected using simple random sampling. Data were collected by researcher and three trained assistants. Chi-square test and binary logistic regression were used for identifying associations and predictors, respectively. The level of significance was set at p < 0.05. Results: Findings show that 260 (63.6%) and 179 (25.6%) have ever and currently used Bitter kola/Kola nut, respectively. Also, 14 (7.8%) used Bitter kola/Kola nut alone while 165 (92.2%) used it in addition to other substances, especially with alcohol 123 (68.7%). Bitter kola use was associated with age (p = 0.037), gender (p < 0.001), occupation (p = 0.001), and number of children (p < 0.011). Identified predictors were being a female (AOR 0.79; 95% CI 0.08-0.92) and earning <18,000 Naira (AOR 2.91; 95% CI 2.03-21.54). There was no association of Bitter kola/kola nut use with CD4 count and viral load suppression. Conclusion: Though Kola nut and Bitter kola use was high as in the general population we have not found any effect on treatment outcome among PLWHIV. This calls for more research to ascertain if there are other possible beneficial effects on PLWHIV.

Diagnostic et évaluation de la réponse thérapeutique de la leucémie myéloïde chronique au Mali par l'hybridation in situ fluorescente / Diagnosis and evaluation of the response to treatment of chronic myeloid leukaemia in Mali by fluorescent in situ hybridization

La leucémie myéloïde chronique (LMC) est une hémopathie maligne caractérisée par la présence du chromosome Philadelphie ou du gène de fusion BCR/ABL1. Au Mali, les approches génétiques de diagnostic et d'évaluation de la réponse thérapeutique de la LMC font défaut d'où l'intérêt de développer la méthode FISH (Hybridation in situ en Fluorescence) pour diagnostiquer et évaluer la réponse thérapeutique de la LMC. Méthodes. Nous avons analysé les cellules sanguines de 25 patients référés pour diagnostic ou évaluation thérapeutique de la LMC. Nous avons réalisé la FISH sur des cellules interphasiques et des métaphases, et la capture d'images cellulaires a été faite avec un microscope à épifluorescence. Résultats. Au total, 25 patients ont été inclus dont 16 pour diagnostic et 9 pour évaluation thérapeutique. Nous avons obtenu un taux de succès de 92% pour l'obtention des métaphases. En outre, nous avons observé des réarrangements ABL1/BCR à la FISH chez 22 des 25 patients. Parmi ces 22 patients, 16 ont présenté un patron de signaux typiques et 6 des patrons de signaux atypiques. Conclusion. Nous avons établi la technique FISH au Mali pour le diagnostic et l'évaluation thérapeutique de la LMC et identifié des formes atypiques de la translocation t(9 ;22).

Objective. Chronic myeloid leukemia (CML) is a hematologic malignancy characterized by the presence of the Philadelphia chromosome or its molecular equivalent, the BCR/ABL1 fusion gene. Diagnosis and monitoring of CML are done by detecting this chromosome, the BCR/ABL1 gene, or the BCR/ABL1 transcript. In Mali, genetic tools of diagnosis and follow-up are still lacking, so we did this study with the objectives of developing the FISH technique to diagnose, to follow up, and to characterize the cytogenetic profile of CML patients. Methods. We carried out FISH technique by using the dual color dual fusion probe for BCR/ABL1 on interphase nuclei and metaphases. Slides were scanned with an epifluorescence microscope. Results. A total of 25 patients (16 for diagnostic and 9 for follow-up) were included. We achieved a 92% success rate for obtaining metaphases. The BCR/ABL1 gene fusion signal was present in 22 patients. Among those 22 patients, 16 presented a typical signal pattern and 6 presented atypical signal patterns. Conclusion. We set up the FISH technique in Mali for the diagnosis and the follow-up of CML patients and identified atypical translocation of t(9;22).

Efficacy of Sofosbuvir and Ledipasvir in Comparison to Sofosbuvir and Daclatasvir in Management of Egyptian Chronic Hepatitis C Patients

In Egypt, the prevalence of hepatitis C virus (HCV) antibodies is the highest worldwide by 7.6%. Applying efficient treatment protocol on large scale could decrease HCV prevalence as well as disease burden.The aim of this study is to compare the efficacy of Sofosbuvir plus ledipasvir versus Sofosbuvir plus daclatasvir in management of chronic hepatitis C Egyptian patients with either easy to treat (naive patients with Child score A5)or difficult to treat (interferon experienced).

Assessment of clinical profiles, and treatment outcomesforchildren with diabetic ketoacidosis, in two hospitals selectedfromAddis Ababa, Ethiopia, 2020

Background: Type 1 diabetes mellitus (T1DM) is a common autoimmune disorder that often presents in children.In these patients, diabetic ketoacidosis (DKA) is one of the most common and serious acute complications, which is associated with significant morbidity and mortality. The study aimed to assess the clinical profiles and outcomes of children admitted with DKA. Objective: To assess the clinical manifestations and treatment outcomes of DKA patients in two tertiary hospitals in Addis Ababa. Methods: A hospital-based retrospective analysis was conducted on 175 pediatric diabetic ketoacidosis children,who were admitted to the emergency units of two hospitals in Addis Ababa from September 2015 to February 2020 and whose medical records contained complete pertinent data. Patients were between the ages of 0 to 12 years. Proportional samples were taken from each hospital and data was collected retrospectively using a formatted checklist. The data was checked for its inclusiveness and entered Epi Info. version 4.6 and then transferred into SPSS version 25 software for further analysis. Result: DKA was the presenting manifestation of Diabetes in 78.3% of patients and 21.7% were already known cases of Diabetes. Half (50.9%) of the study participants were diagnosed with DKA in the age range of 5 to 10 years and almost one-third (30.9%) were above the age of 10. A high-income level of the caretakers was found to be protective against DKA during the diagnosis of T1DM. Out of the 175 children admitted, 12 passed on, resulting in a mortality rate of 6.9%. Conclusion: The majority of the known DM patients presented with DKA after the omission of insulin and a newly diagnosed T1DM at first presentation. The age of presentation and clinical symptoms of the studied participants were like other international studies. Community education regarding the signs and symptoms of childhood DM can further prevent the development of DKA. [Ethiop. J. Health Dev. 2022; 36(2):000-000]

Les données ont été collectées à la division provinciale de la sante, du sitrep de la République Démocratique du Congo et le site l'OMS. Résultats : En RDC, la guérison et le décès des cas de COVID 19 ont été observées respectivement dans 90% et 2,6 % des cas. Conclusion: En RDC, la guérison et le décès des cas de COVID 19 ont été observées respectivement dans 90% et 2,6 % des cas. Conclusion : La RDC reste le pays de l'Afrique centrale ayant enregistré plus de décès lié à la Covid 19. Nous pensons qu'il est important de réévaluer notre stratégie de riposte contre la Covid - 19. La couverture des mesures promotionnelle et préventive est faiblement observée dans notre pays.

Treatment outcomes among HIV-positive orphaned and non-orphaned children on antiretroviral therapy in Johannesburg, South Africa

Background. Limited research investigating treatment outcomes for HIV-positive orphans compared with non-orphans has shown mixed results, with several studies indicating that HIV-positive orphans are at greater risk of delayed access to HIV care and poor antiretroviral therapy (ART) adherence, while other data suggest that ART outcomes of orphans can be similar to those of non-orphans. Understanding the impact of orphan status on short-term ART outcomes could improve targeted intervention strategies, and subsequent long-term treatment and developmental outcomes, for HIV-positive infants, children and adolescents.Objectives. To evaluate the relationship between orphan status and ART outcomes among HIV-positive infants, children and adolescents initiating ART at two large public sector HIV clinics in Johannesburg, South Africa.Methods. This was a retrospective cohort study of HIV-positive children aged <18 years initiating standard first-line ART between June 2004 and May 2013. Using propensity scores, orphans and non-orphans were matched for age, sex, World Health Organization stage and ART regimen. The effect of orphanhood on attrition from care (all-cause mortality and loss to follow-up) was evaluated using Cox proportional hazards regression analysis, and its effect on having a detectable viral load (≥400 copies/mL) at 12 months on ART using binomial regression analysis with modified Poisson distribution.Results. A total of 251 (29.4%) orphans (maternal, paternal or both) and 603 (70.6%) non-orphans were included at ART initiation. Following multiple imputation for missing data and propensity score matching, 222 orphans and 222 non-orphans were included. Orphans had a median age of 8.0 years (interquartile range (IQR) 4.9 - 10.7) and non-orphans 7.4 years (IQR 4.2 - 10.2). A total of 12 (5.4%) orphans and 33 (14.9%) non-orphans experienced attrition from care during the first 12 months on ART (adjusted hazard ratio 0.32, 95% confidence interval (CI) 0.17 - 0.63). Among those alive and in care, with a viral load at 12 months on ART, 18.0% of orphans (33/183) and 14.8% of non-orphans (24/162) had a detectable viral load (adjusted risk ratio 1.15, 95% CI 1.04 - 1.28).Conclusions. Orphans were less likely than non-orphans to experience attrition, but among those in care at 12 months, orphans were more likely to have detectable viral loads. Lower attrition among orphans may be due to their being in institutional or foster care, ensuring that they make their visits; however, their higher rates of non-suppression may result from lack of psychosocial support or stigma resulting in struggles to adhere. Additional research investigating age-specific outcomes will be important to elucidate these effects further

Outcome of hyperglycemic emergencies in a tertiary hospital, South East, Nigeria

Background: Hyperglycemic emergency (HE) is typically represented by diabetic ketoacidosis, (DKA) and hyperosmolar hyperglycemic state (HHS). It is a common cause of hospitalization due to diabetes mellitus (DM) and is associated with considerable mortality. In South East Nigeria, there is a paucity of studies on the treatment outcome of HE, hence the need for this study. Objective: The aim and objective of the study were to determine the outcome of treatment of adult persons living with diabetes managed for HE at Federal Medical Centre (FMC), Umuahia. Materials and Methods: This was a prospective study in which 110 consecutive adult patients managed for HE at FMC, Umuahia, were recruited. Data obtained included a total number of medical and diabetic admissions within the study period. For participants that met the inclusion criteria for the study, their bio­data, blood pressures, level of consciousness at presentation or while being treated, random plasma glucose, plasma electrolytes, urea, creatinine, and plasma 3­beta­hydroxybutyrate were noted and/or measured. Similarly, urine sample was collected from each participant for analysis (glucose, protein, and ketone). The outcome measures were patient's survival, hospitalization duration, and death. Analysis of data was done using SPSS 20.0 and the level of statistical significance was set at P < 0.05. Results: Of the 110 participants recruited, there were 46 (41.8%) males and 64 (58.2%) females. HE constituted 15.6% of the total medical admissions within the study period with a mortality of 10%. DKA and mixed form of HE were the predominant patterns in the study. While hospitalization duration was variable, no female participant was discharged against medical advice. Conclusion: The study showed that HE is a frequent acute complication of DM in this region ofNigeria and that HE typically presents as DKA and mixed form.

Apport de l'éducation thérapeutique sur le niveau psychologique des malades diabétiques au service de médecine de l'hopital du Mali 2018

Objectif: la prise en charge des malades atteints de diabète se fait en mettant l'accent prioritairement sur la composante « biologique » par rapport aux autres déterminants de la santé à savoir l'aspect psychosocial. Ce travail avait pour objectif d'étudier l'apport de l'éducation thérapeutique sur le niveau psychologique des patients. Méthode : une étude transversale, réalisée dans le service de médecine de l'Hôpital du Mali durant le premier semestre 2018 et qui a concernée tous les 115 malades hospitalisés pendant cette période. Résultats: parmi ces malades, 52,20% avaient plus de 50 ans, avec 52,2 % de sexe féminin contre 47,8% pour le sexe masculin. La dépression a été constatée chez 64,31% des patients, les patients qui n'ont jamais reçu d'Education Thérapeutique constituaient 67,83%, la corrélation était significative entre le niveau psychologique du patient et sa participation à une éducation thérapeutique avec un coefficient de corrélation r= 0,518 et un niveau p<0,001. Conclusion: éduquer un patient permet de l'aider à supporter sa maladie et à bien la gérer. Cependant, cette éducation est complexe parce qu'il s'agit d'une véritable formation devant aboutir à un transfert de compétences du soignant vers le soigné

The outcome of patients on hemodialysis at university teaching hospital of Kigali (CHUK) in a period of september 2014 to march 2017 - A retrospective study on patients with acute and chronic renal failure

Background: Kidney dysfunction is both a national and international problem. Its incidence is increasing in the general population, mostly due to the high prevalence of diabetes, hypertension and the long-term consequences of acute kidney injury. The incidence and prevalence of kidney dysfunction necessitating dialysis are unknown in Rwanda as studies are lacking.Methodology: This study describes the outcomes of the patients who received hemodialysis at CHUK. Data was retrospectively collected and statistically analyzed for 152 patients treated in the hemodialysis unit at CHUK between September 2014 and March 2017.Results: The results have shown that 51.3% and 48.7% of the population being studied were identified to have acute kidney injury and chronic kidney failure respectively. The main risk factors for hemodialysis treatment were hypertension (48%), diabetes mellitus (46.7%), eclampsia (13.2%), and volume deficit (15.8%). Hyperkalemia, pulmonary edema, encephalopathy, and other uremic symptoms were present in 39-43% of patients and were the most common indications for hemodialysis. Encephalopathy and poor oxygen saturation were independent risk factors for death. 20.6% could not afford the usual provision of three sessions of hemodialysis per week and therefore didn't receive dialysis as frequently as recommended. Forty-five patients (20.6%) could not afford the usual provision of three sessions of hemodialysis per week and received less frequent dialysis.Conclusion: There is high mortality in patients referred for hemodialysis in CHUK. Almost half of the patients have chronic renal failure and require permanent renal replacement therapy. Many patients limit therapy due to financial reasons

Description and early clinical outcome of patients with omphalocele admitted to a tertiary hospital in Kigali, Rwanda over a three-year period ­ a cross-sectional study

BACKGROUND: Studies suggest that patients with omphalocele have poor outcomes which are associated with the high rate of associated congenital abnormalities. A variety of surgical management techniques have been described, with some requiring equipment not available in resource-limited countries. OBJECTIVES: This study aimed to describe associated abnormalities, management and early hospital outcomes of patients with omphalocele.METHODS: A retrospective study of newborns diagnosed with omphalocele hospitalized from January 2014 to December 2016 at a tertiary level facility, the University Hospital of Kigali (CHUK) in Kigali, Rwanda. Case-file review of included newborns and analysis of the data collected was performed with SPSS version 16.0. RESULTS: Thirty-one patients were hospitalized with omphalocele during the three-year study period. A limited number of investigations were done to diagnose possible associated congenital abnormalities. Three patients (9.7%) were found to have cardiac abnormalities, nine (27.0%) had suspected genetic abnormalities including Trisomy 13, 18 and Beckwith Wiedemann Syndrome. In terms of management, ten patients (32.3%) underwent primary closure. Sixteen patients (51.6%) developed sepsis during hospitalization. Of the thirty-one patients hospitalized, nine (27.0%) died in the hospital. The only factor found to be associated with increased mortality was the size of the omphalocele, with small omphaloceles associated with lower mortality than large omphaloceles (OR 0.909, P-value 0.028).CONCLUSION: Mortality of these patients is significant and slightly higher in patients with larger omphalocele. Newborns with omphalocele should receive appropriate investigations to diagnose associated congenital abnormalities and have early recognition and prompt management of complications, especially sepsis. The results are limited by the small sample size and limited investigations performed to detect associated abnormalities

Success rate of probing in children with congenital nasolacrimal duct obstruction in Menellik II referral hospital

Introduction: The timing of probing for congenital nasolacrimal duct obstruction (CNLDO) has been a matter of controversy. This study was conducted to assess the success rate of probing in children with congenital nasolacrimal duct obstruction and to evaluate the association between success rate and age at the time of intervention. Methods: A prospective study was conducted between April 2014 and March 2015 on 71 children diagnosed to have congenital nasolacrimal duct obstruction. Patients were divided into three age categories. Group A was (1-4 years), group B (4- 7 years), and Group C (7-9 years). Probing was performed by two ophthalmic plastic and lacrimal surgeons under light sedation. Statistical analysis was conducted using Statistical Package for Social Sciences version 17.0. Chi-square test and Fisher's exact test with P value less than 0.05 were used to examine the relationship between success rates of probing and age.Results: A total of 101 eyes of 71 children, were included in the analysis. The overall probing success rate was found to be 88.1%. The success rate of probing was 96.0 % in group A, 82.4% in Group B and 33.3% in group C. Statistical analyses showed that there were significant differences in the success rate among these age groups (P< 0.0001).Conclusion: This study confirmed that success rate of probing is greatest in children between 1-4 years and declines with increasing age. Hence, earlier diagnosis and probing are recommended and can be taken as a first line treatment for children with reasonable outcome
