Outbreak of leptospirosis among canyoning participants, Martinique, 2011.

Two gendarmes who participated in canyoning activities on 27 June 2011 on the Caribbean island of Martinique were diagnosed with leptospirosis using quantitative real-time polymerase chain reaction (qPCR), 9 and 12 days after the event. Among the 45 participants who were contacted, 41 returned a completed questionnaire, of whom eight met the outbreak case definition. The eight cases sought medical attention and were given antibiotics within the first week after fever onset. No severe manifestations of leptospirosis were reported. In seven of the eight cases, the infection was confirmed by qPCR. Three pathogenic Leptospira species, including L. kmetyi, were identified in four of the cases. None of the evaluated risk factors were statistically associated with having developed leptospirosis. Rapid diagnostic assays, such as qPCR, are particularly appropriate in this setting ­ sporting events with prolonged fresh-water exposure ­ for early diagnosis and to help formulate public health recommendations. Participants in such events should be made specifically aware of the risk of leptospirosis, particularly during periods of heavy rainfall and flooding.

[Occupational exposure to syphilis during venous ulcer curettage in Martinique]. / Accident professionnet d'exposition à a syphilis a près curetage d'ulcere veineux en Martinique.

The purpose of this report is to describe the first case of occupational exposure to syphilis. This accident occurred during curettage of a venous ulcer in a 68-year-old woman in Martinique Island. The patient presented primary syphilis without HIV. This case points out the need for enhanced syphilis screening in epidemic areas.

[Infectious keratitis and cosmetic lenses: a five-case retrospective study]. / Kératites infectieuses et lentilles cosmétiques : étude rétrospective de cinq cas.

PURPOSE: To determine the characteristics of infectious keratitis related to plano cosmetic lenses. METHODS: Retrospective case study of a series of infectious keratitis among plano cosmetic lenses wearers. The main parameters were demographic data, medical history, risk factors for infectious complications and keratitis severity criteria, microbiological results, clinical course, and final visual acuity. RESULTS: Five patients were included, all females, ranging from 15 to 50 years of age. Four were emmetropic. One patient had undergone refractive photokeratectomy a few months before. All had risk factors for infectious complications. The fundamental causes of infections were diverse: bacterial abscesses, keratomycosis, and amoebic keratitis. All presented severity criteria. In two cases, the keratitis led to severe consequences with legal blindness requiring penetrating keratoplasty in one case. DISCUSSION: Infectious keratitis in plano cosmetic lenses wearers is not rare and may have dramatic consequences. Sales are specifically regulated and the lenses are considered cosmetic products, not medical devices. The sales regulations for plano cosmetic lenses should be updated, as several countries have already done after encountering many serious incidents.

[Mycotic keratitis and endophthalmitis caused by unusual fungi: Lasiodiplodia theobromae]. / Kératomycose et endophtalmie d'étiologie exceptionnelle: Lasiodiplodia theobromae.

We report a case of endophthalmitis caused by the fungus Lasiodiplodia theobromae. A 68-year-old man was referred to the hospital for right ocular pain since experiencing right ocular branch trauma 2 weeks before. The best-corrected acuity was limited to hand motion. Slit-lamp examination showed a large corneal abscess and an anterior chamber reaction. The patient underwent systemic and local antibiotic therapy, and corneal scraping for microbiological diagnosis. Sabouraud-chloramphenicol-gentamicin agar disclosed filamentous fungus, which was treated with oral itraconazole and topic amphotericin B. Molecular biology revealed Lasiodiplodia theobromae. Despite antimycotic drugs, severe panophthalmia occurred very quickly and led to evisceration. This case report describes Lasiodiplodia theobromae as the cause of keratomycosis and discusses risk factors and clinical features of fungal keratitis in order to improve prognosis by earlier treatment.
