[Ebola virus disease: Clinical presentation, prognosis and treatment]. / Maladie à virus Ebola : présentation clinique, aspects pronostiques et principes thérapeutiques.

The clinical spectrum of Ebola virus disease (EVD) ranges from very serious forms with organ failure and death within days to paucisymptomatic forms and perhaps even asymptomatic. The authors propose a focus on the clinical manifestations of EVD, on prognosis and on therapeutic aspects (excluding resuscitation). This work extracts from the literature the main data gathered during the 2014-2015 epidemic that raged in Guinea Conakry and Sierra Leone. These two countries, even if they are separated by a border, are one and the same population base. The characteristics of the epidemic in Liberia have not been analyzed. The authors have treated EVD patients in the health workers treatment center of Conakry and enrich this work about their personal experience.

[Global management of patients with ebola viral disease, experience of the Healthcare workers Treatment of Conakry, Guinea]. / Prise en charge globale du patient contaminé par le virus Ebola, expérience du Centre de traitement des soignants de Conakry, Guinée.

The Healthcare Workers Treatment Center of Conakry, Guinea, was inaugurated in january 2015. It is dedicated to the diagnosis and the treatment of healthcare workers with probable or confirmed Ebola viral disease. It is staffed by the french army medical service. The french military team may reconcile their medical practice and the ethno-cultural imperatives to optimise the patient adherence during his hospitalization.

[Miliary cerebral Histoplasma capsulatum in an HIV-negative patient]. / Miliaire cérébrale à Histoplasma capsulatum chez un patient séro-négatif pour le VIH.

A 58 year-old man who lived in Africa for 17 years, presented, four years after returning to western France, acute confusion and weight loss. He had no fever and no immunosuppression. Clinical examination revealed Babinski sign, mucosal ulcerations of the mouth and hepatomegaly. The lumbar puncture revealed a meningitis and MRI showed a few parenchymal enhancing masses in the brain. Stereotaxic biopsies were performed. Specific culture and coloration were positive for the diagnosis of cerebral histoplasmosis. At the beginning, antifungal treatment with amphotericin B and itraconazole provided improvement. But seizures occurred and the treatment by carbamazepine induced decreased blood level of itraconazole. Despite itraconazole IV the patient died. This observation illustrates the difficulties in diagnosis and treatment of cerebral histoplasmosis and the various patterns of drug interactions.

[Acute rhabdomyolysis and primary human immunodeficiency virus type 1 infection: a new observation]. / Rhabdomyolyse aiguë associée à une primo-infection à VIH-1: une nouvelle observation.

INTRODUCTION: Acute human immunodeficiency virus type 1 infection is a clinical and biological misleading and often undiagnosed illness. Laboratory studies frequently demonstrate abnormalities. Acute rhabdomyolysis is rarely reported. EXEGESIS: Authors report the case of an African man who presented with acute fever, cough, diarrhea, conjunctivitis, thrombocytopenia, lymphopenia, and rhabdomyolysis without other possible cause. HIV test and detection of plasma p24 antigen were initially negative but were controlled positive and associated with high level of viral RNA. CONCLUSION: Symptomatic primary human immunodeficiency virus infection presenting with acute rhabdomyolysis was diagnosed. Diagnosis of primary HIV-1 infection must be considered in young people and patients at risk who present with acute rhabdomyolysis and fever.

[Streptococcus pyogenes: a rare etiology of non-gonococcal urethritis and balanitis in the adult]. / Streptococcus pyogenes: une cause exceptionnelle d'urétrite et de balanite non gonococcique de l'adulte.

Urethritis and balanitis due to S. pyogenes are very uncommon. The authors report the case of a 22 year-old male patient, presenting with this association, the first case reported in France. There was no associated STD.

[Acute encephalitis concurrent with primary infection by Schistosoma mansoni]. / Encéphalite aiguë contemporaine d'une primo-invasion bilharzienne à Schistosoma mansoni.

A 24-year-old man returning from a trip to Mali was hospitalized for acute encephalitis and fever in association with acute primary infection by Schistosomiasis mansoni. Bilharziasis was suspected from the epidemiological context and presence of eosinophilia. Diagnosis was confirmed by serological testing. Specific treatment using praziquantel and corticotherapy was successful. Central nervous system involvement attributable to embolization of eggs or ectopic migration of adult worms has been reported in association with chronic Schistosomiasis by S. japonicum or S. mansoni. There have been few reports of acute neuroschistosomiais during the acute primary phase of infestation by S. mansoni. Etiology probably involves immunoallergic mechanisms.

[Disseminated and central nervous system Histoplasma capsulatum infection mimicking neoplasm: difficulties in diagnosis, failure in management]. / Miliaire cérébrale pseudonéoplasique révélatrice d'une histoplasmose disséminée à Histoplasma capsulatum: difficultés diagnostiques, échec thérapeutique.

INTRODUCTION: Infection with Histoplasma capsulatum (Hc) is a rare importing disease in metropolitan France, the most often minor but sometimes letal in its spread form. EXEGESIS: A 58 years old French man, HIV seronegative, was admitted for an alteration of its general condition, disorder and buccal ulcerations. He had a prostate cancer history and came back in France after 17 years in Central Africa. The imaging showed numerous cerebral nodes, a bilateral adrenal tumor, and pulmonary calcifications. Histoplasmosis diagnosis has been done after neurosurgical cerebral biopsy which displayed characteristic Hc. The sick man died 4 months later with multivisceral failures, in spite of amphotericine B treatment followed by oral then intraveinous itraconazole. CONCLUSION: Even in an old tropical residence, ones can be able to conjure up a deep exotic fungal infection, and most specifically Hc histoplasmosis, in front of meaningful multivisceral lesions. Disseminated histoplasmosis (HD) with neurological location is misleading, mimicking tuberculosis or cancer. In order to obtain formal mycological evidence, ones have to make adapted biopsies. Antifungal agents must take into account medicinal interaction. Therefore, prognosis is bad, according to inoculum, immunodeficiency, age of disease and diagnosis delay.

[Danger of malaria self-treatment. Acute neurologic toxicity of mefloquine and its combination with pyrimethamine-sulfadoxine]. / Danger de l'auto-traitement de réserve du paludisme. Toxicité neurologique aiguë de la méfloquine et de l'association pyriméthamine-sulfadoxine.

BACKGROUND: Mefloquine and pyrimethamine-sulfadoxine combination are recommended, as is quinine, for self-administered malaria prophylaxis. Patients should be carefully informed about appropriate use of this therapeutic scheme and advised on the importance of strict compliance to avoid overdose. CASE REPORT: We report the case of a patient who did not follow the prescribed dosage and who developed acute neurological disorders after overdosing. The patient developed seizures attributable to the sulfadoxine-pyrimethamine combination and mefloquine encephalopathy. DISCUSSION: Sulfadoxine-pyrimethamine-related seizures are exceptional and result from an overdose of pyrimethamine. The neurotoxicity of mefloquine is well-known and is particularly frequent at curative dosage. Toxic encephalopathy is a serious neurological manifestation which is slowly reversible depending on individual predisposition. Anti-malaria prophylaxis requires concerted efforts on the part of the traveler and the prescribing physician. Self-administration schemes can be both most useful and dangerous due to expected benefits and potential risks.

[Plasmodium vivax: therapy update]. / Plasmodium vivax: actualités thérapeutiques.

IMPACT OF PLASMODIUM VIVAX WORLDWIDE: Plasmodium vivax is the most widespread malanal agent in the world. Unlike Plasmodium falciparum, P. vivax can cause early or late recurrence and is not fatal (benign tertian malaria). EMERGENCE OF RESISTANT STRAINS: P. vivax strains resistant to chloroquine, then primaquine, have emerged over the last decade, creating the need for a new therapeutic strategy. TREATMENT OF PRIMARY DISEASE: Generally, chloroquine is the first intention treatment, excepting patients who also have P. falciparum infection or a strain with suspected resistance to chloroquine. Mefloquine, quinine and halofantrine are also logical alternatives. TREATMENT OF RECURRENT DISEASE: A schizonticidal agent should be given followed by a hypnozoitocidal agent, primaquine. Primaquine dosage should now be raised or adjusted to the patient's weight. THERAPEUTIC PERSPECTIVES: Tafenoquine, delayed-release amino-8-quinoleine, is a potential alternative for primaquine for the treatment of recurrences. Studies are also in progress to evaluate the role of primaquine as a prophylaxic agent.
