[Pulmonary nocardiosis and sarcoidosis]. / Nocardiose pulmonaire et sarcoïdose.

Infectious complications are rarely observed in the course of sarcoidosis. Only small series or cases reports of infection are described in sarcoidosis. Corticosteroids-induced immune suppression, pulmonary fibrosis and T-CD4 lymphopenia, are often present. Pulmonary nocardiosis is an important cause of opportunistic infection in immunosuppressed patients, and the incidence of this infection is increasing. Pulmonary nocardiosis manifests as an acute, subacute or chronic infection with a marked tendency towards remissions and exacerbations. We report a case of pulmonary nocardiosis in a patient with sarcoidosis followed for pulmonary fibrosis receiving corticosteroids. During the investigation of pyrexia and dyspnea, evidence of Nocardia spp. infection was found in the bronchial secretions. Six months of trimethoprim/sulfamethoxazole therapy ensured further resolution of this pleuropulmonary infection. Pulmonary nocardiosis is exceptional in sarcoidosis and mainly occur, in patients receiving corticosteroids, and with CD4+ T-lymphocytopenia. Sarcoidosis by itself does not appear to be a risk factor of opportunistic infection.

[Malaria in the United Nations troops in the Democratic Republic of the Congo during 2005]. / Importance du paludisme au sein des troupes Onusiennes en République Démocratique du Congo, 2005.

This prospective study examined malaria among United Nations troops participating in Operation MONUC in the town of Bunia in the Democratic Republic of Congo from April through October, 2005. Of 245 soldiers hospitalized, 105 were diagnosed with malaria, 93.6% with Plasmodium falciparum. All but one were men, and their median age was 43.5 years (range:29-52 years). South African (40/105) and Moroccan (22/105) soldiers accounted for the majority. Cases were collected mainly from May through July.

Pandemic influenza A(H1N1)2009 in Morocco: experience of the Mohammed V Military Teaching Hospital, Rabat, 12 June to 24 December 2009.

On 12 June 2009, Morocco was the first country in North Africa to report a laboratory-confirmed case of influenza A(H1N1)2009 virus infection. This study describes the epidemiological and clinical characteristics of 240 laboratory-confirmed cases among 594 outpatients with influenza-like illness at the Mohammed V Military Teaching Hospital, Rabat, from 12 June to 24 December 2009. Real-time reverse transcription-PCR was used to confirm the infection. The epidemic peaked in weeks 47 to 49 (16 November to 6 December 2009). The mean age of cases was 23 years (standard deviation: 14 years). Cough was the most common symptom in 200 cases (83%), followed by fever (≥38 °C) in 195 (81%). Diarrhoea or vomiting was reported in 12 (5%) patients. None of the cases developed any complications and no deaths occurred during the study period.

[Acquired ichthyosis revealing an Hodgkin's disease]. / Ichtyose acquise révélant une maladie de Hodgkin. Une nouvelle observation.

INTRODUCTION: Acquired ichthyosis is a rare condition that usually reveals malignant diseases. CASE REPORT: A 70-year-old man was admitted with weight loss, diffuse ichthyosis, lymphadenopathy of the inguinal lymph nodes and elevated inflammatory markers in peripheral blood. Histology of the lymph node revealed mixed-cellularity Hodgkin disease. The evolution was fatal in spite of the chemotherapy. DISCUSSION: Acquired ichthyosis is a cutaneous paraneoplastic syndrome, generally related to hematologic malignancies. A possible pathomecanism is the stimulation of epidermal growth secondary to the production of epidermal growth factor (EGF) by tumour cells. Acquired ichtyosis can rarely reveal systemic or infectious diseases. It can also be drug-induced or idiopathic.
