Posterior sternoclavicular joint dislocation in a young male: a case report.

The traumatic dislocation of the posterior sternoclavicular joint is a serious injury with possibly severe complications and therefore has to be managed with the greatest caution. We report the case of a young male with a posterior dislocation of the medial clavicle with compression of the brachiocephalic artery as well as the esophagus. Open reduction and placement of a wire cerclage were performed with a good postoperative outcome.

Prevalence, clinical presentation, and risk factors of chronic venous disease in Cameroon: A general population-based study.

INTRODUCTION: Chronic venous disease is a global public health problem, with high morbidity and economic distress. There is scarcity of data on this disease in sub-Saharan Africa. METHODS: We conducted the first population-based study over a period of 20 months from 1st February 2020 to 30th September 2021 in the 10 regions of Cameroon. A stratify sampling method was chose to select study site. Socio-demographic data, personal and family history, anthropometric parameters, clinical signs, illustrative images, CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification revised in 2004, VCSS (venous Clinical Severity Score) and risk factor assessment score were used to construct the survey form. Chi-squared test and Fischer exact test were used to compare the prevalence of chronic venous disease across different potential risk factors (sex, age category, previous history of deep vein thrombosis, hypertension, diabetes, smoking status, obesity). Simple and multiple logistic regression models were used to obtain crude and adjusted odds ratio for risk factors associated with chronic venous insufficiency. Statistical analyses were done with R version 4.2 for Linux and the threshold for statistical significance was 0.05. RESULTS: A total of 6578 participants were included in the study, with a mean age of 41.09 ± 16.02 years with female predominance (54.3%). The prevalence of chronic venous disease was 21.8% (95% CI: 20.8-22.9) and the prevalence of chronic venous insufficiency (C3-C6) was 7.02% (n = 462). Night cramps (43.2%), oedema (21.7%), lower limbs pain (20.4%) mostly worsens by walking and heavy legs (16.2%) were more common symptoms. The mean total venous clinical severity score was 0.69 ± 1.76 and this score had a significant positive correlation with C classification (p < .001). In the multivariate analysis, the following factors were independently associated with CVD: Male gender (aOR: 1.27; 95%CI: 1.04-1.56; p = .021), retired people (aOR: 46.9; 95% CI: 12.6-174.5; p < .001), hypertension (aOR: 289.5; 95%CI: 169.69-493.1; p < .001), diabetes (aOR: 2.19; 95% CI: 1.21-3.96; p = .009), obesity (aOR: 10.22; 95%CI: 7.67-13.62; p < .001). Smoking appears as a protective factor (aOR: 0.18; 95%CI: 0.10-0.30; p < .001). CONCLUSION: Chronic venous disease is frequent in Cameroon and main traditional cardiovascular risk factors are associated to this condition. Systematic screening of the CVD in these specific groups could reduce the burden of the disease and its economic impact.

Doxycycline vs Hydroxychloroquine + Azithromycin in the Management of COVID-19 Patients: An Open-Label Randomized Clinical Trial in Sub-Saharan Africa (DOXYCOV).

Objective We aimed to compare the safety and efficacy of a doxycycline-based regimen against Cameroon National Standard Guidelines (hydroxychloroquine plus azithromycin) for the treatment of mild symptomatic COVID-19. Methods We conducted an open-label, randomized, non-inferiority trial in Cameroon comparing doxycycline 100 mg, twice daily for seven days versus hydroxychloroquine 400 mg daily for five days and azithromycin 500 mg at day 1 and 250 mg from day 2 through 5 in mild COVID-19 patients. Clinical recovery, biological parameters, and adverse events were assessed. The primary outcome was the proportion of clinical recovery on days 3, 10, and 30. Non-inferiority was determined by the clinical recovery rate between protocols with a 20-percentage points margin. Results One hundred and ninety-four participants underwent randomization and were treated either with doxycycline (n = 97) or hydroxychloroquine-azithromycin (n = 97). On day 3, 74/92 (80.4%) participants on doxycycline versus 77/95 (81.1%) on hydroxychloroquine-azithromycin-based protocols were asymptomatic (p = 0.91). On day 10, 88/92 (95.7%) participants on doxycycline versus 93/95 (97.9%) on hydroxychloroquine-azithromycin were asymptomatic (p = 0.44). On day 30, all participants were asymptomatic. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) polymerase chain reaction (PCR) test was negative on day 10 in 60/92 (65.2%) participants who were assigned to doxycycline and in 63/95 (66.3%) participants who were assigned to hydroxychloroquine-azithromycin. None of the participants were admitted for worsening of the disease after treatment initiation. Conclusion Doxycycline 100 mg twice daily for seven days proved to be safe and non-inferior in terms of efficacy when compared to hydroxychloroquine-azithromycin for preventing clinical worsening of mild symptomatic or asymptomatic COVID-19 and achieving virological suppression.

Factors predicting in-hospital all-cause mortality in COVID 19 patients at the Laquintinie Hospital Douala, Cameroon.

BACKGROUND: Despite being a global pandemic, little is known about the factors influencing in-hospital mortality of COVID-19 patients in sub-Saharan Africa. This study aimed to provide data on in-hospital mortality among COVID-19 patients hospitalized in a single large center in Cameroon. METHODS: A hospital-based prospective follow-up was conducted from March 18 to June 30, 2020, including patients >18 years with positive PCR for SARS-COV-2 on nasopharyngeal swab admitted to the Laquintinie Douala hospital COVID unit. Predictors of in-hospital mortality were assessed using Kaplan Meir survival curves and Weibull regression for the accelerated time failure model. Statistical significance was considered as p < 0.05. RESULTS: Overall 712 patients (65,7% men) were included, mean age 52,80 ± 14,09 years. There were 580 (67,8% men) in-hospital patients. The median duration of hospital stay was eight days. The in-hospital mortality was 22.2%. Deceased patients compared to survivors were significantly older, had a higher temperature, respiratory rate, and heart rate, and lowest peripheral oxygen saturation at admission. After adjusting for age, sex, and other clinical patient characteristics, increased heart rate, increased temperature, decreased peripheral oxygen saturation. The critical clinical status was significantly associated with increased in-hospital mortality. In contrast, hospitalization duration greater than eight days and the use of hydroxychloroquine (HCQ) + azithromycin (AZM) therapy was associated with decreased risk of in-hospital mortality. CONCLUSION: One in five hospitalized COVID-19 patients die in a low-middle income setting. Critical clinical status, dyspnea, and increased heart rate were predictors of in-hospital mortality. This study will serve as a prerequisite for more robust subsequent follow-up studies. Also, these results will aid in revising national guidelines for the management of COVID-19 in Cameroon.

Impact of treatment delays on outcome of acute testicular torsion: a 15-year retrospective study.

INTRODUCTION: Preservation of the testicle is directly associated with the duration of torsion. The aim in this retrospective study was to identify factors that influence pre-and in-hospital times and measure the extent to which these times affect testicle survival. PATIENTS AND METHODS: A retrospective review of 116 patients who underwent exploration for testicular torsion between 2000 and 2015. Patients were divided into orchiectomy and salvaged testicle groups. Times in patient management and clinical features were compared with Mann-Whitney, chi-squared, and Fisher exact tests. Multivariate logistical regression was used to identify independent factors associated with orchiectomy. RESULTS: The median prehospital time of 48 h (15.4-138 h) in the orchiectomy group was longer than the 2.4 h (1.6 h-5.2h) in the salvaged group. Patients examined by a general practitioner (GP) prior to presenting at hospital had a median prehospital time of 48 h, compared to 3 h for patients not examined before presentation at hospital. In-hospital times between admission and operation room, as well as times between ultrasonography and operation room, were also longer in the orchiectomy group. Previous GP consultation (OR = 27.26, 95% CI 2.32-320.59, p = .009), prehospital time (OR = 1.04, 95% CI 1.01-1.07, p = .003) and nausea (OR = 9.25, 95% IC 1.33-64.52, p = .025) were independent predictive factors associated with orchiectomy. CONCLUSION: Prehospital time was a determining factor in orchiectomy. For each extra hour of prehospital delay, the risk of orchiectomy increased by 4%. The rate of orchiectomy was higher among patients who first consulted a GP.

Eighteen years lasting bronchial foreign body: A case report in Cameroon, sub-Sahara Africa.

INTRODUCTION: Foreign body aspiration represents an important cause of morbidity and mortality during childhood. A neglected aspirated foreign body can last for years, leading to complications that are sometimes difficult to manage, dramatically affecting the quality of life of the patient. CASE REPORT: We report the case of a 29-year-old female who presented with eighteen-year history of recurrent cough, choking, and respiratory infections following a foreign body aspiration. The course was complicated by a chronic secondary lung abscess, successfully managed by combined medical and surgical treatment. DISCUSSION: In low-income countries like ours, foreign body aspiration is often misdiagnosed. The often delayed management due to low socioeconomic status can lead to serious complications. To the best of our knowledge, it is the longest period of bronchial foreign body retention reported in the medical literature in Africa. CONCLUSION: Foreign body aspiration is common in childhood and requires early recognition and treatment, in order to avoid complications that can be very serious or even fatal.

Epidemiology of acutely decompensated systolic heart failure over the 2003-2013 decade in Douala General Hospital, Cameroon.

AIMS: Acutely decompensated heart failure (HF) (ADHF) is a common cause of hospitalization and mortality worldwide. This study explores the epidemiology and prognostic factors of ADHF in Cameroonian patients. METHODS AND RESULTS: This was a retrospective study conducted between January 2003 and December 2013 from the medical files of patients followed at the intensive care and cardiovascular units of Douala General Hospital in Cameroon. Clinical, electrocardiographic, echocardiographic, and biological data were collected from 142 patients (58.5% men; mean age 58 ± 14 years) hospitalized for ADHF with reduced ejection fraction (HFrEF), whose left ventricular ejection fraction was <50%, or alternatively whose shortening fraction was <28%, both assessed by echocardiography. The commonest risk factors associated with HFrEF were hypertension (59.2%), diabetes mellitus (16.2%), tobacco use (14.1%), and dyslipidaemia (7.7%), respectively. The major causes of HF in hospitalized patients were hypertensive heart disease (40%, n = 57); hypertrophic cardiomyopathy (33.8%, n = 48); and ischemic heart disease (21.8%, n = 31). The most frequent comorbid conditions were atrial fibrillation (25.4%, n = 36) and chronic kidney disease (18.3%, n = 26). Major biological abnormalities included increased bilirubinemia >12 mg/L (87.5%, n = 124); hyperuricaemia >70 mg/L (84.9%, n = 121); elevated serum creatinine (65.6%, n = 93); anaemia (59.1%, n = 84); hyperglycaemia on admission >1.8 g/L (42.3%, n = 60); and hyponatraemia <135 mEq/L (26.8%, n = 38). At admission, 33.8% (n = 48) of patients had no pharmacological treatment for HF. The most frequently used therapies upon admission included furosemide (50%, n = 71), angiotensin-converting enzyme inhibitors (ACEIs; 40.1%, n = 57); spironolactone (35.2%, n = 50); digoxin (26%, n = 37); beta-blockers (17.7%, n = 25); angiotensin-receptor blockers (ARBs; 7%, n = 10); and nitrates (7.0%). The overall in-hospital mortality rate was 20.4%. Factors associated with poor prognosis were systolic blood pressure <90 mmHg [odds ratio (OR) 3.88; confidence interval (CI) 1.36-11.05, P = 0.011], left ventricular ejection fraction <20% (OR 7.48; CI 2.84-19.71, P < 0.001), decreased renal function (OR 1.03; CI 1.00-1.05, P = 0.026), dobutamine use for cardiogenic shock (OR 2.74;CI 1.00-7.47, P = 0.049), pleural fluid effusion (OR 3.46; CI 1.07-11.20, P = 0.038), and prothrombin time <50% (OR 3.60; CI 1.11-11.68, P = 0.033). The use of ACEIs/ARBs was associated with reduced in-hospital mortality rate (OR 0.17; CI 0.02-0.81, P = 0.006). CONCLUSIONS: Hypertensive heart disease, hypertrophic cardiomyopathy, and ischemic heart disease are the commonest causes of HF in this Cameroonian population. ADHF is associated with high in-hospital mortality in Cameroon. Hypotension, severe left ventricular systolic dysfunction, renal function impairment, and dobutamine administration were associated with worst acute HF outcomes. ACEIs/ARBs use was associated with improved survival.

Thromboembolic risks in patients with COVID-19: major concern to consider in our management.

COVID-19 pandemic is an emergent cardiovascular risk factor and a major cause of mortality worldwide. Thromboembolism is highly suspected as a leading cause of death in these patients through vascular inflammation caused by SARS COV2. Until now there is no real treatment of COVID-19 and many proposed drugs are under clinical trials. Considering the high incidence of thromboembolic events in critically ill patients with COVID-19, prevention of this disorder should be essential in order to reduce mortality in these patients.

COVID-19 pandemic: do we need systematic screening of patients with cardiovascular risk factors in Low and Middle-Income Countries (LMICs) for preventing death?

Late mortality after cardiac interventions over 10-year period in two Cameroonian government-owned hospitals.

BACKGROUND: Cardiac surgery is a growing activity in Sub-Saharan Africa, however, data related to long-term mortality are scarce. We aimed to analyze outcome data of cardiac interventions in two hospitals in Cameroon over 10 years' period. METHODS: we conducted a retrospective analytical and descriptive study at the Douala General Hospital and Yaoundé General Hospital. All patients operated between January 2007 and December 2017, or their families were contacted by phone between January and April 2018 for a free of charges medical examination. RESULTS: Of a total of 98 patients operated during the study period, 8 (8.2%) were lost to follow-up. Finally, 90 patients [49 (54.4%) women and 41 (45.6%)] men were included. The mean age was 49±22 years (range, 13-89 years). The surgical indications were valvular heart diseases in 37 (41.1%) cases, congenital heart diseases in 11 (12.2%) cases, chronic constrictive pericarditis in 4 (4.4%) cases, and intra cardiac tumor in 1 (1.1%) case. Valve replacement was the most common type of surgery carried out in 37 (41.1%) cases-mostly with mechanical prosthesis. Pacemaker-mostly dual-chambers were implanted in 36 (40.0%) patients. The median follow-up was 26 months. The overall late mortality was 5.7%, and the overall survival rates at 5 and 10 years were 95.5% and 94.4% respectively. The overall survival rates at 5 and 10 years for mechanical valve prosthesis were 93.3% and 90% respectively. The survival at 10 years was 100% for patients with bioprosthesis. The survival rates at 10 years were 94.1% and 100% respectively for dual and single chamber pacemaker. CONCLUSIONS: Long-term outcome of cardiac surgery in hospitals in Cameroon are acceptable with low mortality rate. However, outcome metrics beyond mortality should be implemented for a prospective data collection.

Application of the Canadian C-Spine rule and nexus low criteria and results of cervical spine radiography in emergency condition.

INTRODUCTION: The Canadian C Spine Rule (CCR) and the National Emergency X-Radiography Utilization Study (Nexus) low criteria are well accepted as guide to help physician in case of cervical blunt trauma. METHODS: We aimed to evaluate retrospectively the application of these recommendations in our emergency department. Secondly we analyzed the quality of cervical spine radiography (CSR) in an emergency setting. RESULTS: 281 patients with cervical blunt trauma were analyzed retrospectively. The CCR and the NEXUS rules were respected in 91.2% and 96.8% of cases respectively. No lesions were found in 96.4% of patient. A lesion was present in 1.1% of patient and suspected in 2.5% of patient. The quality of CSR was adequate in only 37.7% of patient. The poor quality of CSR was due either to the lack of C7 vertebrae visualization in 64.6% or other lower vertebrae in 28%. Other causes included the absence of open mouth view (8%), the absence C1 vertebrae visualization (3.4%), artifact in 2.3% and the absence of lateral view in 0.6% of patient. CONCLUSION: CCR and NEXUS are widely used in our emergency department. The high rate of inadequate CSR reinforces the debate about it's utility in emergency condition.

Association of urinary sodium excretion with blood pressure and risk factors associated with hypertension among Cameroonian pygmies and bantus: a cross-sectional study.

BACKGROUND: High salt intake increases blood pressure (BP) and hypertension risk. This study aimed to examine association of urinary sodium excretion with BP and hypertension correlates among Cameroonian pygmies under hunter-gatherer subsistence mode and Bantus, living in urban area under unhealthy behavioral habits. METHODS: In this cross-sectional cluster sampling study, we randomly enrolled rural pygmies living in Lolodorf and urban Bantus living in Douala. The World Health Organization steps questionnaire was used to collect socio-demographic and lifestyle data. Height, weight, BP and single overnight spot urine samples were obtained in all participants. BP was measured in triplicate. Urinary sodium and potassium excretion was determined by flame photometry. Data were recorded and analyzed using SPSS 16.0. RESULTS: We included 150 Pygmies and 150 Bantus aged 38 ± 12 years and 33 ± 11 years, respectively (p <  0.0001). Compare to Bantus, pygmy's height and weight were respectively: 1.54 ± 0.09 m vs 1.72 ± 0.12 m; and 54.4 ± 9.2 kg vs 77.2 ± 14.8 kg, all p <  0.0001. Age-standardized prevalence of hypertension was 3.3% among Pygmies and 28% among Bantus (p <  0.0001). Age-adjusted systolic and diastolic BP were lower in Pygmies than in Bantus (107 ± 12 vs 119 ± 17 mmHg and 71 ± 11 vs 78 ± 13 mmHg respectively, all P <  0.0001). BP increased with age but to a lesser extent in Pygmies (all p <  0.01). Urinary sodium excretion was lower in Pygmies than in Bantus (46.9 ± 32.4 vs 121.5 ± 61.0 mmol/l, p <  0.0001). Systolic and diastolic BP were positively associated with urinary sodium excretion in Bantus (all p <  0.05). In the two groups, urinary potassium excretion was similar, and was not related to blood pressure. In the total study group and in Bantus taken separately, urinary sodium excretion was higher in hypertensive than in normotensive subjects. Multivariable logistic regression showed that urinary sodium excretion, Bantu status and age emerged as independent determinants of hypertension in the whole study group (OR (95%CI): 1.012 (1.005-1.018); 11.408 (3.599-36.165); 1.095 (1.057-1.135) respectively, p <  0.0001). CONCLUSION: Hunter-gatherer pygmies exhibit low level of urinary sodium excretion related to low rate of hypertension and slower BP increase with age. Salt intake was a major driver of hypertension in our study population. Our findings highlight the need of efforts to implement nationwide prevention programs promoting risk factor screening and healthier lifestyles including reduction of dietary salt intake in Cameroonian.

[Platelet collection in cardiac surgery: first experience with apheresis at the General Hospital in Douala]. / Prélèvement de plaquettes pour la chirurgie cardiaque: première expérience de d'aphérèse à l'Hôpital Général de Douala.

Cardiac surgery with extracorporeal circulation (ECC) is usually associated with the loss of a significant amount of blood. Adequate prophylaxis against blood loss and good perioperative hemostasis are known as processes limiting postoperative bleeding. Until now, the need for platelets in patients operated with extracorporeal circulation in our Department has been compensated for by total blood transfusion or platelet concentrates collected from several donors. We here report our first experience with platelet concentrate collection by apheresis at the General Hospital in Douala.

Prevalence, awareness, treatment, and control of hypertension among rural and urban dwellers of the Far North Region of Cameroon.

OBJECTIVE: To assess the prevalence and determinants of high blood pressure (BP) and awareness, treatment, and control rates in the Far North Region of Cameroon, where these variables have not been explored so far. METHODS: In total, 889 individuals (41.5% women) aged at least 18 years participated in a cross-sectional survey conducted in Maroua (urban area) and Tokombere (rural area) from November 2014 to May 2015, using a multistage cluster sampling frame. Anthropometric variables, BP, and fasting capillary glucose were assessed in all participants. Hypertension was defined as BP at least 140/90 mmHg or antihypertensive therapy and BP control as BP less than 140/90 mmHg. Prevalence estimates were age standardized to the Cameroon population. RESULTS: The prevalence of hypertension was 37.8% (rural: 34%; urban: 41.2%; men: 38.8%; women: 37.9%). Hypertension was associated with urban environment (odds ratio: 1.42; 95%; confidence interval 1.06-1.89), age at least 70 years (4.06; 2.02-6.14), male sex (4.06; 2.02-6.14), abdominal obesity (2.36; 1.54-3.61), and high blood sugar (2.01; 1.31-3.08). Among individuals with hypertension, 18.6% (rural: 17.9%; urban: 19.5%) were aware of having high BP. Among those aware, 29.3% (rural: 17.3%; urban: 36.3%) reported receiving treatment, of whom 16.3% (rural: 22.6%; urban: 4.2%) had BP controlled. Awareness, treatment, and BP control levels were higher in women than men. CONCLUSION: Hypertension is highly prevalent in Far North Cameroon and awareness, treatment, and control rates are low. Efforts to improve detection, treatment, and control of hypertension in Cameroon are needed.

Arterial stiffness and cardiometabolic phenotype of Cameroonian Pygmies and Bantus.

BACKGROUND: Pygmies living in the Central African rainforest with a traditional hunter-gatherer lifestyle have a low incidence of cardiovascular diseases. Because of progressive loss of traditional habitat and ancestral lands, some Pygmies have migrated to urban areas and adopt specific Bantu lifestyles such as increased salt consumption and a sedentary way of life. We tested the hypothesis that migrant Pygmies could present with hemodynamic and metabolic characteristics different from those of traditional in-situ Pygmies and possibly closer to those of Bantu farmers. PATIENTS AND METHODS: The study included 148 Pygmies (94 traditional and 54 migrants) and 164 Bantus. Peripheral and central hemodynamics, aortic pulse wave velocity (PWV), and augmentation index corrected for heart rate (AIx) were measured, as well as fasting lipid profile. Urinary sodium and potassium excretion was also measured on a morning spot. RESULTS: Compared to Bantus, Pygmies had lower height (even between men and women, but men were taller than women in the three groups), weight, waist and hip circumference, peripheral and central blood pressure, total, low-density lipoprotein, and high-density lipoprotein cholesterol and apolipoprotein B100 levels, sodium urinary excretion, and lower prevalence of the metabolic syndrome. By contrast, they had a higher waist-to-hip ratio, and higher triglycerides levels, as compared to Bantu farmers. PWV and AIx did not differ between Bantus and Pygmies. Compared to traditional in-situ Pygmies, migrant Pygmies were not taller when adjusted for sex, had lower brachial and central blood pressure, higher PWV (adjusted for mean arterial pressure, BMI, and sex), and higher apolipoprotein B100 levels. In the whole population, multivariable analysis revealed that PWV was independently associated with age, weight, height, mean arterial pressure, total cholesterol, and hip circumference, whereas AIx was independently related to age, sex, height, heart rate, diastolic blood pressure, and group (from Bantu farmers to Pygmies). CONCLUSION: Comparisons between Bantus and Pygmies, and between migrant Pygmies and traditional in-situ Pygmies, showed mixed results, with favorable and deleterious hemodynamic and metabolic characteristics in all groups. This could be due to increased contacts between these populations, which blunt the expected differences and because the beneficial effects of the hunter-gatherer subsistence mode of traditional in-situ Pygmies are counterbalanced by unhealthy behavioral habits.

Hypoxemia after pneumothorax exsufflation: a case report.

We describe a 36-year-old patient who was admitted to the emergency ward for acute dyspnea due to a spontaneous pneumothorax. He was successfully drained but shortly after presented a severe hypoxemia due to pulmonary oedema secondary to pulmonary re-expansion. The physiopathology behind this complication is still unknown. We will try to describe this complication and its predictive factors.

[Legionnaires' disease complicated by rhabdomyolysis and acute renal failure: about a case]. / Légionellose compliquée d'une rhabdomyolyse et d'une insuffisance rénale aiguë: à propos d'un cas.

Legionnaires' disease is a bacterial disease of the respiratory system caused by a gram-negative germ whose clinical manifestation can be benign limiting to flu-like syndrome or can be more severe being characterized by pneumonia which may be complicated by multisystem disease that can lead to death. We report the case of a 48 year-old patient with rhabdomyolysis complicated by acute renal failure following Legionella pneumophila pneumonia. We here highlight the pathophysiological aspects and treatment of this rare complication during Legionella infection.

Outcome of permanent vascular access for haemodialysis in patients with end-stage renal disease in Cameroon: results from the pilot experience of the Douala general hospital.

Background Chronic Kidney disease is a major health problem in the world. Native arteriovenous Fistula (AVF) is well established as the best vascular access for haemodialysis. Little is known about the outcome of AVF in sub-Saharan Africa. We aim to analyze the outcome of patients undergoing AVF creation during the pilot program established at the Douala general hospital (DGH). Method This was hospital-based, longitudinal study with a retrospective phase (April 2010-January 2014) and a prospective phase (January 2014-April 2014). All consecutive patients operated for AVF creation were included in this study. Socio-demographics data, functionality, and complications were analyzed. Results Eighty-one patients including 52 men were enrolled in this study (49 prospectively and 32 retrospectively). The mean age was 52, 3 years (range 18-81 years). Hypertension (66, 7%), diabetes (17, 3%), and HIV (8, 6%) were the most observed co-morbidities. About 96.3% of AVF were native and 3.7% were prosthetic graft. Radiocephalic AVF was performed at a rate of 77.8%. The primary function rate was 97.7% and the mean follow-up period 43.4 weeks. The overall rate of complications was 44.4% of whom 30.5% were early, 30.5% secondary, and 39% lasted. The treatment of these complications was conservative in 48.7% of cases. Conclusions The results of the pilot program of AVF creation at the DGH are encouraging. However, the sustainability of this project requires human capacity building.

Cannabis body packing: a case report.

Drug traffic is a major concern worldwide. We report a case of a 27-year old male who presented with a diffuse abdominal plain to the emergency department. Abdominal X-ray demonstrated multiple foreign bodies along the intestinal tract, which were found to be cannabis packets. The patient was treated conservatively with a good result.
