Impact of serodiagnosis on the management of Lyme borreliosis at Angers University Hospital.

INTRODUCTION: Lyme borreliosis (LB) is an emerging arthropod-borne disease the diagnosis of which is made on clinical and biological data. We assessed the Angers University Hospital physicians' management of LB, in case of positive serology, and estimated their compliance to European recommendations (EUCALB). METHODS: We retrospectively included 75 cases with positive ELISA serologies confirmed by Western-Blot, performed at the Angers University Hospital between 2008 and 2012. RESULTS AND DISCUSSION: There were 4 cases of early localized phase, 26 of early-disseminated phase (including 17 cases of neuroborreliosis), and one case of late phase. The curative management complied with EUCALB guidelines in 28 cases out of 31. CONCLUSION: Serology remains a reference diagnostic tool for LB, as long as the practitioner is aware of the main clinical and biological criteria.

[Rhinofacial conidiobolomycosis associated with cervical, thoracic and brachial localizations: one clinical case in Nigeria]. / Conidiobolomycose rhinofaciale avec localisations cervicales, thoraciques et brachiales: à propos d'un cas nigérian.

We report here the clinical case of a Nigerian adult patient who received medical care during October 2010, at the Center for Diagnosis and Treatment of Buruli ulcer in Pobè (Benin). He presented a massive facial tumor associated with several subcutaneous (cervical, thoracic and upper limbs) nodules, evolving since several years. Tissue samples collected at Pobè medical center were addressed to the mycology and histology laboratories of Angers University Hospital (France), according to the medical exchange agreement between the two institutions about the diagnosis and treatment of Buruli ulcer disease. Histological examination showed a Splendore-Hoeppli phenomenon, consisting of a granulomatous reaction made of eosinophilic polynuclear cells surrounding rare, large and irregular, non-septate hyphae. A filamentous fungus was isolated by cultivation of the clinical samples, which was identified as Conidiobolus coronatus. The patient was treated orally with daily doses of ketoconazole (400 mg per day). After 4 months of treatment, a marked regression of the facial lesion was obtained. A first constructive facial surgery was achieved, but the patient did not attend the second step. This case report allows us to remind the mycological diagnosis of this exotic mycosis, but also to emphasize the main difficulties encountered in medical management in the developing countries.
