[Clinical manifestations in patients exposed to an environmental toxic accident (Abidjan, Ivory Coast 2006)]. / Manifestations cliniques chez les sujets exposés à un accident toxique environnemental (Abidjan, Côte d'Ivoire 2006).

INTRODUCTION: In 2006, 528 tons of petroleum toxic waste have been released in Abidjan (Ivory Coast) during a major environmental accident. This study was aimed to describe the clinical manifestations provoked by these toxic waste. METHODS: We have analysed the records of patients admitted to the university hospital of Cocody (Abidjan) following exposure to toxic waste. All the information were recorded on specific files or on notification files created by the physicians of the National Institute of Public Health, the authority charged with the supervision of this exercise. The files were completed by the physician in the course of the examination of the patient. RESULTS: Over a period of 3-month-period, 10,598 patients were examined. The clinical manifestations affected all age groups. They were dominated by respiratory symptoms: pulmonary (74.5%) and upper respiratory (31.0%). Pulmonary symptoms included cough (48.8%), chest pain (37.9%), dyspnoea (9.5%) and a few cases of hemoptysis. Digestive symptoms mainly comprised abdominal pain (36.2%), diarrhea (23.0%), abdominal distension (19.9%) and vomiting (9.9%). The other symptoms were neurological, ophthalmic, cardiovascular and gynaecological. More than 96% of patients presented with at least two symptoms. The respiratory symptoms were significantly more frequent in patients over the age of 17 while diarrhea and vomiting were more often found in patients less than 17 years old. Chest pain was significantly more common in men while abdominal pain and vomiting predominated in women (P=0.001). CONCLUSION: The clinical consequences of toxic waste exposure were varied and sometimes serious. A medium- and long-term evaluation of the subjects is required.

[Correlation of the manifestations of tuberculosis and the degree of immunosuppression in patients with HIV]. / Corrélations des manifestations de la tuberculose pulmonaire avec le degré d'immunodépression au VIH.

CONTEXT: Correlation of the manifestations of tuberculosis and the degree of immunosuppression in patients with HIV. BACKGROUND: The advent of HIV has contributed to the increase in the number of people with tuberculosis. The clinical and paraclinical of TB/HIV co-infected are polymorphic and function of immune status. OBJECTIVES: To determines the clinical and paraclinical characteristics of TB related to different levels of CD4 lymphocytes. METHODOLOGY: A retrospective case series based on analysis of 450 patients with both TB/HIV co-infections. It focused on the records of patients with pulmonary smear-positive (TPM +) with a positive HIV status. The effect of immunosuppression was analyzed in groups based on the CD4 count (<200/mm(3), of 200-350/mm(3) and>350/mm(3)), in a chronological fashion from April to September 2010 until there were 150 patients in each CD4 group. RESULTS: Among the 450 patients, 71.1% were between 25 and 45years old. The clinical signs were more significant as the level of CD4 fell. The clinical signs were predominantly fever (93%) and weight loss (62.7%). Pulmonary cavitation (59.3%), infiltrates (38.7%) and the location of the lesions at the lung apex (72%) were more common in the third group patients. By contrast, extra pulmonary lesions (mediastinal lymphadenopathy, pleurisy) and normal x-ray (9.3%) were more frequent in patients of the first group. The scarcity of cavitations (22.3% compared to 59.3% CD4>350) and the increase in associated lesions became more marked if patients were immunocompromised. Hematologic, hepatic, renal disorders were more frequent and severe in the most immunocompromised patient group. CONCLUSION: HIV-associated tuberculosis has an atypical clinical, radiological, biological presentation and is more severe when there is significant immunosuppression.
