Epilepsy in a cohort of Senegalese children

Epilepsy is a significant health public problem in Senegal with an estimated prevalence of 8 to 14%. The aim of this study was to determine the clinical and electroencephalographic features of epilepsy in a cohort of Senegalese infants, search for etiological factors and determine the impact of disease on school life. This retrospective study concerned 459 children who attended the neurological outpatients clinic at the Fann hospital, Dakar, Senegal, between July 2003 and December 2006. All were aged under 19 years. Among the 135 children with idiopathic epilepsy, 23.7% had parental consanguinity and 37.77 % familial epilepsy. Rolandic epilepsy and epilepsy with absences were more frequent but several infants with idiopathic epilepsy were not classified. Non-idiopathic epilepsy was noted in 312 children. In this group, estimates of parental consanguinity and familial epilepsy were of 21.79 and 17.94%, respectively. Etiological factors were predominantly pregnancy and birth abnormalities (28.84%) and central nervous system infection (20.19%). Twelve children had febrile seizures. Of patients with idiopathic epilepsy, 65.18% were attending school versus only 9.29 with non-idiopathic epilepsy.     

Therapeutic results and evolution of Black African patients with follicular lymphoma: Ivory Coast experience

We reported in this study a treatment results about 36 Africans patients with follicular lymphoma. The average age of patients was 18 to 73 years old with a median age at 50.83 years old and a sex ratio of 1. Clinical characteristics of patients are mainly represented by advance stage with 70% of stage III and IV of Ann Arbor classification. Histological, we mainly notified follicular lymphoma constituted of small cells 50%, followed by mixed follicular and large cells lymphomas with respectively 27.78 and 22.22%. Using varieties of therapeutics regiments, we obtained 41.67% of complete remission. There were significant correlations between complete remission and histology subtypes. Indeed, the follicular lymphomas constituted by large cells and mixed cells had higher rate of complete remission with respectively 46.67% and 40% in relation with those of small cells with a higher failure rate. Median follow-up was 24 months, the estimated 5-years overall survival and event-free survival were 22%. After a long period, 25 cases of death have been reported, 5 cases of losing sight and 6 patients are still alive and following treatment. Our results are lowers than the reported case in developing country. This none satisfying was in relation with the lower socio-economical level of the main part of the patients. The short survival delay time of our patients didn't permit time to observe transformation case in diffuse large cell lymphomas.     

The traffic elbow. A series of 9 cases

"Traffic elbow" is a condition occurring when high energy trauma involves a patient's elbow resting on the window of the car or completely outside it. This is a prospective study over 30 months of 9 patients with "traffic elbow" and therefore sufferring complex open trauma to the elbow. There were 8 men and 1 woman with a median delay of 4 hours before arrival in hospital. The dominant member was affected in 3 cases. The severity of the lesions, using the Mangled Extremity Severity Score (MESS), was more than 7, comprising lesions corresponding to type 1 of the complex trauma of the superior member (TCMS) in 2 patients and a MESS score of between 3 and 6 corresponding to types 2 or 3 of the TCMS for the other 7 patients. The therapeutic possibilities are limited considering the frequent context of polytrauma. In 4 cases we performed a debridement and external humero-ulnar fixation, in 3 cases a debridement and stabilization with Kirschner's wires completed by a fenestrated cast, and in 2 cases a lifesaving amputation. All patients, except those that had had amputation, developed deep sepsis that resolved after adequate treatment. Assessment of the non-amputee patients according to the Mayo Performance Score, yielded more than 70% of bad results. The authors stress the gravity of these lesions whose prognosis is guarded both concerning mobility of the elbow and the frequent neurovascular complications.     

几内亚首都科纳克里某校高中生艾滋病相关知识、态度的调查

目的了解几内亚首都科纳克里某校高中生艾滋病相关知识、态度的现状。方法2011年11月,采用横断面调查方法,用自制问卷调查几内亚首都科纳克里某中学294名高中生的艾滋病相关知识和态度。测量相关知识和态度的得分情况,并比较不同人口学特征学生得分的差异。结果回收有效问卷284份（96.6%）。调查对象年龄范围为15～18岁,其中男生148人,女生136人。艾滋病相关知识总分范围为4～25分（满分26分）,各条目答对率范围为35.9%～84.9%,只有78.2%的学生知识得分超过13分;被调查学生艾滋病相关态度总分范围为0～8分（满分10分）,各条目态度积极率范围为9.5%～90.5%,仅有27.1%的学生态度较积极;不同性别、年龄和城乡的学生之间知识及态度总分差异无统计学意义。结论几内亚高中生艾滋病知识面狭窄现象较明显,存在较消极态度,需大力加强艾滋病的健康教育工作。     

Effectiveness of a strategy to improve adherence to tuberculosis treatment in a resource-poor setting: a cluster randomized controlled trial

Context  Poor adherence to treatment remains a major obstacle to efficient tuberculosis (TB) control in developing countries. Innovative strategies to improve access and adherence to treatment are needed. Objectives  To assess the effectiveness of a contextualized intervention strategy aimed at improving patients' adherence to treatment and to evaluate its impact on TB control in a resource-poor country in Africa with prevalent TB infection. Design, Setting, and Patients  A cluster randomized controlled trial, conducted between June 2003 and January 2005, at 16 government district health centers in Senegal. Patients older than 15 years with newly diagnosed sputum smear–positive pulmonary TB were randomly assigned to the intervention or control group. Intervention  The intervention strategy included reinforced counseling through improved communication between health personnel and patients, decentralization of treatment, choice of directly observed therapy (DOT) supporter by the patient, and reinforcement of supervision activities. In the control group, the usual TB control program procedures remained unchanged. Main Outcome Measure  Proportion of patients successfully completing the 8-month course of treatment and the proportion of patients defaulting from treatment. Results  A total of 1522 patients were recruited into the study. Treatment was successful for 682 (88%) of 778 patients recruited in the intervention group, and for 563 (76%) of 744 patients recruited in the control group (adjusted risk ratio [RR], 1.18; 95% confidence interval [CI], 1.03-1.34). The proportion of patients defaulting was reduced in the intervention group to 5.5% (n = 43) compared with 16.8% (n = 125) in the control group (adjusted RR, 0.43; 95% CI, 0.21-0.89). Conclusion  The intervention package based on improved patients counseling and communication, decentralization of treatment, patient choice of DOT supporter, and reinforcement of supervision activities led to improvement in patient outcomes compared with the usual TB control procedures. This approach may be generalized in the context of TB control programs in resource-poor countries. Trial Registration  clinicaltrials.gov Identifier: NCT00412009
