Methods: We conducted a retrospective epidemiological survey of consultations at the eye unit of the Douala General Hospital over the last 20 years (from January 1, 1990 to December 31, 2009). Results: Out of the 1927 cases of blindness, 1000 were unilateral, corresponding to a hospital prevalence of 1.84% and 927 cases were bilateral, corresponding to a hospital prevalence of 1.71%. No statistically significant difference was noted between the two (P = 0.14). The leading causes of bilateral blindness were cataract (50.1%), glaucoma (19.7%), and diabetic retinopathy (7.8%) while the leading causes of unilateral blindness were cataract (40.4%), glaucoma (14.1%), and retinal detachment (9.1%). Cataract (51.2%), cortical blindness (16.3%), and congenital glaucoma (10%) were the leading causes of bilateral blindness in children aged less than 10 years. Conclusion: Blindness remains a public health problem in the Douala region with a hospital prevalence which is relatively higher than the national estimate given by the National Blindness Control Program.

Abstract: Background: Recent reports indicate that the use of mammography in breast screening plays a major role in reducing breast cancer-related deaths. It helps to improve quality of care and patient information. However, in Cameroon, there are no organized general breast screening programs which give women the opportunity to regularly screen their breasts, except for the few who take their own initiative for breast screening. Purpose: This study aimed to list indications and results of mammography and/or breast ultrasounds at Douala General Hospital in order to determine the proportion of routine mammographic screening. Method: This descriptive cross-sectional study was carried out at Douala General Hospital using pre-established data sheets. The study recruited all patients who met the selection criteria and reported to the radiology and medical imaging department for breast screening using physical examinations, mammography and/or ultrasounds. Results: The study recruited 372 patients, 96.8% of whom were between 40 to 50 years old. The reasons given for the medical consultation were systematic screening (33.01%); pain (27.18%) and lumps (25.24%). Breast examination by inspection was normal in 87.1% of women, and by palpation in 66.7%. Mammography revealed nodular opacities (18.3%), spiculated images (4.3%) and micro calcifications (3.2%), while ultrasound identified fibroadenomas (16.48%) and cysts (6.18%). Suspicious lesions (ACR 4 and 5) were discovered in 7.6% of cases by mammography and 8.51% of cases by ultrasound. The results indicated that there was no significant association between the use of clinical examination and mammography (p = 0.754). The use of clinical examination alone for breast screening may not be sufficient. Conclusion: Our findings indicate that in Cemaroon, the routine screening mammography accounts for less than one-third (33.1%) of all indications. Benign lesions were most common, however 7.6% and 8.51% of suspicious malignant lesions were observed using mammography and ultrasound respectively.

Abstract: The diagnosis and management of cerebral gliomas are challenging. The goal of this study was to evaluate the pattern of cerebral gliomas at the General Hospital Douala, Cameroon. A retrospective study was carried out over a period of 10 years. Non-glial lesions were not included. Data were analyzed with Epi info version 7.2.2.6 (Microsoft, Seattle, USA). 220 cases of brain tumors, comprising 56 gliomas (25.46% of all brain tumors) were managed during the study period. The mean age of the patients was 42.93 ± 16.90 years. 35 cases (62.5%) were males. Patients over 15 years of age represented 91.07% (n = 51) of the cases. The most frequent presenting complaints were headache and vomiting with 52 cases (92.86%) and 47 cases (83.93%) respectively. Brain computed tomography was done for all patients. The most frequent histological type was astrocytoma with 22 cases (39.29%) followed by glioblastoma with 20 cases (35.71%). The most performed surgical technique was partial removal with 33 cases (58.93%), followed by open biopsy with 14 cases (25.00%). Radiotherapy was administered to 54 patients (96.43%). The outcome ranged from full recovery in 8 cases (14.29%), recovery with persisting symptoms, in 15 cases (26.79%) and death in 26 cases (46.43%). Seven patients (12.50%) were lost to view. In this series, cerebral gliomas affected most often adult males. Most of them presented with signs of raised intracranial pressure. The outcome was poor with 46.43% of patients dying before 2 years after diagnosis.

Abstract: Traumatic brain injury is the most common injury during childhood comprising 60% to 90% injuries in children. Pediatric traumatic brain injury has peculiarities as compared to adults, such as less severe injuries and better prognosis. The purpose of this work was to study the pattern of pediatric traumatic brain injury at the General Hospital, Douala, Cameroon. This was a retrospective cross-sectional study, from January 1st, 2008 to December 31st, 2017. Included were all complete medical records of children aged 0 to 15 years old treated for traumatic brain injury, and excluded records of obstetric trauma. Data analysis was done by SPSS software version 18.0. One hundred and three cases of pediatric head injuries were recorded during the study period (frequency 10.43%). The mean age was 7.42 ± 5.028 years, and the sex ratio was 2.67 in favor of boys. Road traffic accidents were the most common etiology (44.7%). 83.5% of the patients were transferred to the emergency department of the Douala General Hospital in second intention and by non-medical transport. The traumatic brain injury was mild in 61.20%. The brain computed tomography scan was performed in 99% of the cases and the most observed lesion was cerebral edema (32.74%). Twenty-eight patients underwent surgical operation. 90.28% of patients have recovered fully, and the global mortality was 3.88%. The prevalence of pediatric traumatic brain injuries at the General Hospital, Douala during the last ten years was 10.43%. Most of the patients recovered fully and the mortality was low.

Abstract: Background: Poor sleep quality is reported to be common in hemodialysis patients. However, limited data are available about its prevalence in sub-Saha-ran region. The aim of this study was to assessed sleep quality and its predictors among hemodialysis patients. Methods: We conducted a cross sectional study of 2 weeks in the Douala General Hospital hemodialysis center of Cameroon involving 46 chronic hemodialyzed patients for at least six months with arteriovenous fistula. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and laboratory data were collected in patients’’ fields. Result: Thirty-five (76.1%) subjects reported poor sleep quality. The most frequent abnormal sleep components were subjective sleep quality, sleep disturbances and sleep latency (87%, 85% and 76% respectively). In univariate linear regression, hemoglobin level, sleep quality, sleep latency, sleep duration, habitual sleep efficiency and sleep disturbance were associated with poor sleep quality. In multivariate linear regression only hemoglobin level (p = 0.004) and sleep latency (p = 0.002) were associated with poor sleep quality. Conclusion: Poor sleep quality is frequent in our hemodialysis patients and hemoglobin seems to be a good predictor of sleep quality in these patients.

Abstract: Introduction: Digestive Stomas can be made from the ileum, ascending colon, transverses’ or descending’s order; they can be lateral or terminal. The study is particularly interested in the transverse colostomies to assess their frequency compared to the laterals conducted for a period of 10 years at the Douala General Hospital in the department of digestive surgery. The purpose is, to retrospectively study their indications and complications and critically evaluation the practice. Methods: From December 1999 until December 2009 we identified and collected data from all patients who underwent lateral stoma side under and the clinical features of the holders of a transverse colostomy, as well as major and minor complications raised by nurse’s staff. Results: 110 lateral colostomies were performed, 72 (68%) were transverse colostomies, the average age was 69.5 years (means: 24-95), sex ratio M / F was 0.8 with 60% emergencies cases and at the same time temporary. Acute colonic occlusion (43.1%) cases were our major indication. The complication rate was 44% specific and particularly (32%) cases of major complications such as prolapsed stomas. Monitoring (9.7%) of incisional para stoma, and finally 7% of retractions stoma observed, no ischemia or necrosis observed. Conclusion: Acute occlusion of the colon justifies an indication of a transverse colostomy compared to other emergency stomas; it seems to have fewer complications such as necrosis and ischemia compared to stomas side.

Abstract: Objectives: The objective of this study was to evaluate the interest of MRI in the diagnosis of spinal disorders in our area. Method: It was a cross-sectional, descriptive and retrospective study during a nine-month period from January to September 2015 involving all patients who performed a spine MRI in the Imaging Department of Douala General Hospital. All the patients were scanned using an open-sided mid-field MRI APERTO LUCENT (0.4 T) using sagittal and axial slices in T1-weighted and T2-weighted FSE spin echo and STIR sagittal slices and T1 gado. Water-fat saturation (WFS) slices were obtained after injection of a contrast agent. All the data collected were analyzed using Microsoft Excel 2010 and Sphinx version 4.0. Results: 220 patients were recruited. The mean age was 46.34. There was male predominance with a sex ratio of 1.5. The main indication was lumbar spine pain (36.8%), followed by cervical spine pain, sensory and motor disorder. Neurosurgeon (33.6%), neurologist (23.1%) and rheumatologist (13.6%) were the main referring physicians. The lumbar spine was the most explored (53.2%). Discal hernia (46.6%), arthrosis (31.3%) and degenerative disc disease (25.5%) were the main observed lesion. Infectious disorders were mainly represented by spondylitis (5%); Traumatic disorders by spondylolisthesis (8.6%). Tumors were mainly metastasis (4%). 21.3% of MRI were normal. MRI-clinical concordance was 78.63%. Conclusion: MRI allows an accurate assessment of spinal and spinal cord pathologies without exposing patients to radiation. It helped to confirm or refute the diagnosis suspected by clinics. However, its availability is limited in our country.

Abstract: Background and Objectives: Cerebro-vascular accident or stroke constitutes a major challenge in sub-Saharan Africa. In Cameroon, basic epidemiologic data are not routinely available. Aims: The aim of this study was to determine the type, the associated risk factors, time to admission, the clinical presentation and the case fatality of stroke at the Douala General Hospital (DGH) in Cameroon. Methods: A cross-sectional study was performed from January 1, 2010 to December 31, 2012 at the neurology and intensive care units of the DGH. All patients above 15 years of age with a diagnosis of established stroke were enrolled. For each patient, socio-demographic, clinical and paraclinical data were recorded as well as the duration of hospitalization and the case fatality. Results: In all, 325 patients were enrolled with males constituting 68.1% and general mean age of 58.66 ± 13.6 years. The mean initial consultation delay was 47.36 ± 18.48 hours. The majors cerebro-vascular risk factors were hypertension (81.15%), chronic alcohol consumption (28.3%), diabetes mellitus (20.61%), obesity (18.15%), cigarette smoking (16%), dyslipidemia (8.9%) and atrial fibrillation (3.07%). Ischemic stroke accounted for 52% of cases while 48% were hemorrhagic. The mean duration of hospitalization was 8.58 ± 6.35 days with a case fatality rate of 26.8%. Septic conditions appeared to be the leading cause of death accounting for 35.6% of cases. Conclusion: Stroke in the DGH is associated with a high case fatality rate and hypertension remains the number one risk factor. There is a clear and urgent need for public health authorities to reinforce measures for the control of modifiable stroke risk factors.

Abstract: Introduction: The prevalence of cervical cancer in Cameroon is 80.73/100,000 women, with an estimated incidence of 40/100,000 women-years. It is a real public health problem. There is no systematic and effective screening program for cervical cancer in our country, despite the advent of visual tests that are simple to use, low cost, and adapted to the modest income of our social groups. Objectives: We aimed at determining the usefulness and place of visual tests in screening for cervical dysplasia and cervical cancer for its implementation at the Laquintinie Hospital Douala, Cameroon. Methods: We conducted a prospective analytic cross-sectional study of cervical dysplasia and cervical cancer screening by visual testing at the Laquintinie Hospital Douala from December 1, 2016 to March 31, 2017. Data collection was by consecutive non-probabilistic method and consenting sexually active women older than 21 years were enrolled for study. Data analysis was with Epi InfoTM version 7. Associations were done with the Chi square, student t-test and Fischer’s exact test where appropriate. Bivariate and multivariate analysis was done and reported as odd ratios, adjusted odd ratios and 95% confidence intervals. Statistical significance was set at P < 0.05. Results: We received 1590 women, of whom 1506 (94.7%) screened for dysplastic lesions and cervical cancer during the study period. The results obtained were: 1417 (94.1%) had a normal result; 64 (4.2%)
