Abstract: Background: The hospital environment is largely contaminated with pathogenic microorganisms. This colonization is a threat for hospitalized patients, especially in high-risk services. The purpose of this study was to identify the germs found on surfaces and medical devices in some departments of the General Hospital of Douala, and to establish their susceptibility profile to most commonly used antibiotics in this health facility. Results: We collected 114 surface and medical device samples, and seeded different culture media for Gram-positive and Gram-negative aerobic bacteria. Of the total samples, 108 were positive and 137 bacterial strains were isolated. The colony count revealed a high rate of contamination. Enterobacter cloacae was the most represented specie (53.3%), followed by Pseudomonas aeruginosa (22.6%) and Klebsiella pneumoniae (6.6%). Various coagulase-negative Staphylococci have been isolated in some departments, as well as Cryptococcus laurentii and molds. The isolated strains showed low susceptibility to the antibiotics tested. Enterobacter cloacae showed low susceptibility for all tested molecules, except for carbapenems with rates ranging from 82% to over 94% in Maternity, Intensive Care and Neonatology units. The strains coming from the Haematology Protected Ward were resistant to all antibiotics, except fluoroquinolones with a susceptibility rate of 50% for ofloxacin. Conclusion: The hospital surfaces and medical devices are highly contaminated by environmental bacteria, with low susceptibility rates to antibiotics. Microbiological controls of the environment should be regular in critical areas in order to reinforce measures to prevent diffusion of multi-resistant bacteria.

Abstract: Background and Aims: Diagnostic colonoscopy allows exploration of the colonic mucosa. Indications are multiple. The purpose of this work was to describe the indications and to report the lesions observed during colonoscopy at the General Hospital of Douala. Methods: This was a cross-sectional study with retrospective data collection over a period of 7 years (January 1, 2010 to January 31, 2017). The data collected from the reports were socio-demographic characteristics, indications and lesions observed at colonoscopy. Binary logistic regression allowed us to identify the independent risk factors associated with the presence of tumors and polyps. Results: We included 719 exams. The main indications were rectorrhagia (29.5%), abdominal pain (25.9%) and constipation (17.8%). A colonic lesion was found in 60.1% of cases. A colorectal tumor accounted for 10.3% of cases. Factors independently associated with colonic tumor were complete colonoscopy (aOR: 0.167 95% CI [0.096 - 0.289], p < 0.001), presence of abdominal or rectal mass (aOR: 13.390 95% CI) [5.684 - 31.544], p < 0.001) and weight loss (aOR: 5.143, 95% CI [2.450 - 10.797], p < 0.001). Conclusion: The presence of weight loss, abdominal or rectal mass should motivate the realization of a complete colonoscopy in search of a colorectal tumor. The most observed lesions remain hemorrhoids, polyps and diverticulosis of the colon.
HIV-Associated Central Nervous System Disease in Patients Admitted at the Douala General Hospital between 2004 and 2009: A Retrospective Study

Abstract: Background. Studies on HIV-associated central nervous system (CNS) diseases in Cameroon are rare. The aim of this study was to describe the clinical presentation, identify aetiological factors, and determine predictors of mortality in HIV patients with CNS disease. Methods. From January 1, 2004 and December 31, 2009, we did at the Douala General Hospital a clinical case note review of 672 admitted adult (age ≥ 18 years) HIV-1 patients, and 44.6% (300/672) of whom were diagnosed and treated for HIV-associated CNS disease. Results. The mean age of the study population was years, and median CD4 count was 49 cells/mm3 (interquartile range (QR): 17–90). The most common clinical presentations were headache (83%), focal signs (40.6%), and fever (37.7%). Toxoplasma encephalitis and cryptococcal meningitis were the leading aetiologies of HIV-associated CNS disease in 32.3% and 25% of patients, respectively. Overall mortality was 49%. Primary central nervous system lymphoma (PCNSL) and bacterial meningitis had the highest case fatality rates of 100% followed by tuberculous meningitis (79.8%). Low CD4 count was an independent predictor of fatality (AOR: 3.2, 95%CI: 2.0–5.2). Conclusions. HIV-associated CNS disease is common in Douala. CNS symptoms in HIV patients need urgent investigation because of their association with diseases of high case fatality. 1. Introduction HIV infection is a major cause of morbidity and mortality worldwide and affects 33 million people of whom two-thirds live in sub-Saharan Africa [1]. The clinical presentation is diverse and many organ systems are involved. Its predilection for the nervous system makes it neuroinvasive, can enter the central nervous system (CNS), neurotropic, can live in neural tissues and neurovirulent, and can directly cause disease of the nervous system [2, 3]. This complex HIV-nervous system interaction therefore makes neurological manifestations a frequent complication of HIV. Nervous system disease is the main presenting feature in 10–20% of cases, and over 50% of patients with AIDS have neurological disease in the course of HIV disease [4]. It has also been shown that at autopsy 75–90% of HIV patients have neuropathologic abnormalities [4]. Neurological complications in HIV are highly disease stage specific, and this stage specificity largely reflects the dominant influence of altered immune responses especially cell-mediated defences that characterise later phases of systemic infections [5]. Since the introduction of highly active antiretroviral therapy (HAART) in 1996, the incidence of HIV-associated CNS

Abstract: Background: The diagnosis of tuberculosis (TB) is frequently challenging given that the clinical and radiographic features of TB are often nonspecific. Altered leukocyte count ratios could serve as new tools of diagnostic orientation of tuberculosis. The aim of this study was to assess the diagnostic value of the leukocyte count ratios for the diagnosis of TB. Methods: This was a cross-sectional study including cases of newly diagnosed TB patients from registers of the TB treatment center of the Douala General Hospital. Control subjects were healthy volunteers, age and sex matched, recruited at the blood bank. Sociodemographic, clinical data and peripheral blood parameters were collected. The diagnostic value of leukocyte counts was determined using receiver operating characteristics curve analysis. Results: In total, 204 TB patients and 204 control subjects were included in the study. The gender of the participants was equitably distributed in the 2 study groups (male 61.8%; female 38.2%). The median age of TB patients was 33 years while that of control patients was 32 years. The monocyte-lymphocyte count ratio (MLR) and neutrophil-lymphocyte count ratio (NLR) were significantly higher in the TB patients group compared to control group. A NLR >1.19 and MLR >0.29 were identified as cut-off values for discriminating TB patients. The areas under the curves (AUC) were 0.77 and 0.84 for the MLR and NLR respectively. Conclusion: A raised NLR > 1.19 and MLR

Abstract: Background: Venous thromboembolic (VTE) disease burden is increasing worldwide, representing a major cause of cardiovascular death and public health problem. Pulmonary embolism (PE) is the most serious clinical presentation of VTE. Epidemiological and clinical data on PE are still lacking in Africa, particularly in Cameroon. This study aimed at determining the clinical features as well as imaging presentation and outcome of pulmonary embolism. Methods: A cross-sectional study was carried out in three hospitals in Douala. We retrospectively reviewed patient records admitted for PE from January 2009 to May 2017. We collected data on epidemiology, clinical presentation, venous Doppler/pulmonary computed tomographic angiography (CTA), and outcome. Results: We included 103 patients (56 males) with PE. Their median age was 52 years. The main risk factors were obesity (49.5%), hypertension (35.0%), long trip (24.3%) and cancer (18.4%). The most frequent clinical presentations were dyspnoea (83.4%), chest pain (78.6%), and cough (40.8%). Additionally, pleural effusion (32.8%), atelectasis (25.7%) and pulmonary hyperlucency (20.0%) were the most frequent findings on chest X-ray. The main abnormalities found in electrocardiogram were sinus tachycardia (63.4%), S1Q3T3 aspect (37.6%) and right axial deviation (28.7%). Moreover, right cavities dilatation (26.0%), pulmonary artery hypertension (35.0%) and pulmonary artery dilatation (21.0%) were the main echocardiographic findings. Low-molecular-weight heparin (LMWH) was the initial anticoagulant in all cases. There were 19 (18.4%) in-hospital deaths, and the mean hospital stay was 8.5 ± 5 days. Conclusion: PE is not rare in our setting. Obesity, long trip and cancer are the main risk factors, while dyspnoea, chest pain and respiratory distress are the main clinical presentation for PE. LMWH remains the therapeutic agent of choice. Lastly, in-hospital mortality is very high.

Abstract: Background Peripheral neuropathy (PN) which is the most common neurological complication of HIV infection is under recognised and undertreated especially in resource limited settings. This ailment which has a negative impact on the quality of life of HIV/AIDS patients exists in different clinical patterns of which HIV-associated Sensory neuropathy (HIV-SN) is the most common affecting up to two thirds of patients with advanced disease in some settings. In Cameroon where HIV is a major public health problem, the burden of HIV-SN has not yet been well defined. Methods Using the Brief Peripheral Neuropathy Screening (BPNS) tool validated by the AIDS Clinical Trial Group (ACTG) we carried out a cross sectional study to determine the prevalence of HIV-SN and its associated factors among HIV-1 patients at the Douala General Hospital between 1st July and 31st October 2011. HIV-SN was defined as the presence of neuropathic symptoms and at least an abnormal perception of vibrations of a 128Hz tuning fork on the great toe or abnormal ankle reflexes or both and expressed as a percentage of the study population. Results Out of 295 patients studied, 21% had HIV-SN. In HIV-SN patients the median duration of HIV infection was 79.8 months (IQR 46 – 107.5) and their median CD4 count 153cells/μL (IQR 80 – 280). Patient recall and clinical chart review showed that, 83.9% had neuropathic symptoms prior to HAART initiation and 16.1% after HAART initiation. Low CD4 count, history of alcohol intake and history of anti-tuberculosis treatment were strongly associated with HIV-SN (AOR 2.5, 2.8 and 2.9 respectively). Conclusions HIV-SN is common among patients with advanced HIV infection in Cameroon. This simple diagnostic tool (BPNS) should therefore be routinely used to detect those with HIV-SN or at risk so as to minimise the negative impact it has on their quality of life.

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: Objectives: Describe the clinical, aetiological and prognostic features of infectious meningitis in adults at the Douala General Hospital (DGH). Patients and Methods: We carried out a 5-year retrospective cross-sectional study at the DGH, on data from the registers of the bacteriology and biochemistry laboratories. Cases of meningitis were identified from the results of the cerebrospinal fluid (CSF) analysis, and the patient clinical file was obtained. Cases files of patients aged 15 years and above were included. For each patient, sociodemographic, clinical features and hospital mortality data were extracted. Results: During study period, 1877 CSF analyses were recorded and 135 were enrolled for data analysis. Up to 74 patients (55%) were male and the mean age was 40.04 ± 12.5 years. The time lapse between the onset of symptoms and consultation was 12.24 ± 11.16 days. The main clinical signs were meningeal syndrome (96.3%), neck stiffness (71.1%), reduced alertness (64.4%) and confusional states (55.6%). The main aetiology was bacterial (45.19%) withStreptococcus pneumoniae?(45.90%) andNeisseria meningitis?(29.51%) leading. The other aetiologies were viral (21.48%), fungal withCryptococcus neoformans?(20%) and meningeal tuberculosis (13.33%). Fifty eight patients (42.9%) had a positive HIV serology. The mean duration of hospitalization was 9.05 ± 8.1 days, and the total in-hospital mortality was 25.18%. 117 patients (86.8%) had received antibiotherapy before diagnosis. Conclusion: The clinical features of meningitis in the DGH are as in classical description. However, the mortality is high and the major aetiologies appear to be associated with HIV infection at least in part. Prospective multi-centric studies are needed to provide more evidence for the development of staged management guidelines in our resource-limited settings.

Abstract:
Background: The?burden of peripheral artery disease (PAD) is not well known among apparently healthy people in Africa. Aim: To determine the prevalence and associated risk factors of PAD in a group of blood donors seen at the Douala General HospitalCameroon. Methods: Between 1st November 2015 and 30th April 2016, we carried out a cross-sectional study. Participants were consenting adults of both sexes, aged ≥ 21 years who presented for blood donation, and were tested HIV negative. We collected socio-demographic data and their past history. We carried out a physical examination and measured their Ankle-Brachial Index (ABI). We defined PAD as an ABI < 0.9. We also measured their fasting blood glucose and lipid profile. Results: We recruited 103 participants, 55.4% males. The mean age was 33 ± 10 years. The mean ABI on left and right leg was 1.04 ± 0.1 and 1.02 ± 0.1respectively. ABI was higher in males than females both legs (p < 0.05). PAD was seen in 11 (10.7%) participants. This was higher in females than males (3.6% versus 19.2%, p = 0.026). Among those with PAD, 8 (72.7%) were asymptomatic (Males: 100% versus Females: 66%, p
