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: 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 (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.

International Journal of Medical Physics,Clinical Engineering and Radiation Oncology (IJMPCERO) , 2020, DOI: 10.4236/ijmpcero.2020.91004
Abstract: In this work, a method to reduce increase in optical density (OD) caused by multiple scanning in radiochromic film dosimetry in combination with a flatbed scanner is presented. Gafchromic EBT3 films are scanned with Epson Pro 1680 Expression scanner and time intervals of 15 minutes and 30 minutes are observed between consecutive scans to reduce the increase in temperature of the scanner. The maximum variations in OD after consecutive scans are calculated and compared to the values obtained for scans without interruption. For film irradiated to 3 Gy, a time interval of 15 minutes between two successive scans leads to a reduction of the OD increase of 56.2% compared to when films are scanned without interruption. Reductions of OD increase of 86.72% and 78.72% respectively for film irradiated to 1 Gy and 2 Gy are obtained when a time interval of 30 minutes is left between two successive scans. These results show that when time intervals are observed between consecutive scans, the increase in OD has significantly reduced. However, the method has the drawback of increasing the time needed to perform radiochromic film dosimetry.
Wildfire Monitoring and Detection System Using Wireless Sensor Network: A Case Study of Tanzania  [PDF]

Wireless Sensor Network (WSN) , 2017, DOI: 10.4236/wsn.2017.98015
Abstract: This paper proposes a wildfire monitoring and detection system based on wireless sensor network. This system detects fire by monitoring surrounding temperature, humidity and smoke. Once fire is detected, a warning message containing probable location of that fire is immediately sent to the responsible authority over cellular network. In order for the system to be more effective, communities living near forests or national parks can send warning messages through the same system to the responsible authority using their mobile handsets once they witness wildfire or illegal activities. For the system to be fully functional, the only requirement is the availability of cellular network coverage in forests or national parks to enable short message services to take place. The system prototype is developed using Arduino microcontroller, several sensors to detect temperature, relative humidity and smoke as well as wireless network connection modules. At the control center Telerivet messaging platform is used to design the messaging service. The experimental results justify the capability of the proposed system in detecting wildfire in real time.
Place de la Radiotherapie dans la prise en charge therapeutique du sarcome de kaposi epidemique
M Essomba Biwole, A Mouelle Sone
Clinics in Mother and Child Health , 2009,
Abstract: Les auteurs abordent la prise en charge thérapeutique du sarcome de Kaposi associé au VIH, qui pose des problèmes d’indications thérapeutiques, certains auteurs émettant l’idée que les traitements antirétroviraux seuls pourraient suffire pour son traitement. Sur la base d’une expérience de près de dix ans pendant lesquels 720 patients ont été pris en charge, les auteurs passent d’abord en revue les différentes présentations cliniques du sarcome de kaposi associé au VIH. Ils proposent ensuite les indications thérapeutiques, et donnent enfin un peu plus longuement les modalités de la radiothérapie qu’ils proposent pour ces malades.

Abstract: A survey was undertaken in a family medicine practice with a special interest in addiction medicine in Brisbane, Australia.Of 350 patients surveyed, 220 were substance dependent, and 130 were general medical patients. Addicted patients were younger (mean ± S.D. 33.72 ± 8.14 vs. 44.24 ± 16.91 years, P < 0.0001) and had shorter driving histories (15.96 ± 8.50 vs. 25.54 ± 15.03 years, P < 0.0001). They had less driving related medical problems (vision, spectacle use, diabetes) but more fractures, surgical operations, dental trauma and assaults. Addicted patients also had significantly worse driving histories on most parameters measured including percent with driving suspensions (O.R. = 7.70, C.I. 4.38–13.63), duration of suspensions (1.71 ± 3.60 vs. 0.11 ± 0.31 years, P < 0.0001), number of motor vehicle collisions (2.00 ± 3.30 vs. 1.10 ± 1.32, P = 0.01), numbers of cars repaired (1.73 ± 3.59 vs. 1.08 ± 1.60, P = 0.042), rear end collisions (O.R. = 1.90, CI 1.13–3.25), running away after car crashes (O.R. = 26.37, CI 4.31–1077.48), other people hospitalized (O.R. = 2.00, C.I. 0.93–4.37, P = 0.037) and people killed (17 vs. 0 P = 0.0005). Upon multivariate analysis group membership was shown to be a significant determinant of both cars repaired and cars hit when controlled for length of driving history. Hence use of all types of drugs (O.R. = 10.07, C.I. 8.80–14.72) was more common in addicted patients as were general (O.R. = 3.64, C.I. 2.99–4.80) and road (O.R.= 2.73, C.I. 2.36–3.15) trauma.This study shows that despite shorter driving histories, addicted patients have worse driving careers and general trauma experience than the comparison group which is not explained by associated medical conditions. Trauma is relevant to addiction management at both the patient and policy levels. Substance dependence policies which focus largely on prevention of virus transmission likely have too narrow a public health focus, and tend to engender an unrealistically simplistic and tri
