Fungemia in the French department of Mayotte, Indian Ocean: A 10 years survey.

OBJECTIVE: This study aimed at providing original data on fungemia in the Centre Hospitalier de Mayotte in terms of prevalence, epidemiological characteristics of infected patients, yeast species distribution and profile of in vitro antifungals susceptibility. METHODS: A total of 223 positive blood cultures for yeasts were retrospectively reported during the period April 2010-April 2020. RESULTS: Ninety-five episodes were identified corresponding to an incidence rate of 3.7 cases/100,000 inhabitants. The average age of patients was 33.5 years, and 63.3% patients were hospitalized in intensive care unit. The main co-morbidities were surgery in the 30 days prior to fungemia (27.8%), neoplasia (22.8%), parenteral nutrition (17.7%), diabetes (16.5%) and immunosuppressive medications (31.6%). Candida spp accounted for the majority of isolates (92.4%) with a predominance of non-albicans species (55.8% vs 33.7%), including C. albicans (33.7%), C. tropicalis (30.5%) and C. parapsilosis (20%). The antifungal susceptibility profiles did not differ from expected results for each species and did not change significantly over time. DISCUSSION: Fungemia remain frequent hospital infections associated with high mortality in Mayotte. The vast majority of fungemia was due to Candida spp. Non-albicansCandida species reach half of the Candida isolates with a high percentage of C. tropicalis. Surprisingly, no case of candidemia due to C. glabrata were identified. The management of candidemia remains satisfactory and the treatment was adapted according to the international recommendations. However, the high susceptibility of Candida spp. isolates to fluconazole may invite to reconsider the use of this molecule as empirical and first-line treatment of candidemia in Mayotte.

Cutaneous and mediastinal lymphadenitis due to Mycobacterium kansasii.

Mycobacterium kansasii most commonly causes a slowly progressive pulmonary disease. Skin and disseminated infections are seen less frequently and only in immunocompromised hosts. To our knowledge, no case of Mycobacterium kansasii infection or skin infection associated with additional organ involvement in an immunocompetent patient has been reported.

[Lung neoplasms revealing a rare cutaneous tumor: eccrine porocarcinoma]. / Métastases pulmonaires révélatrices d'une tumeur cutanée rare: le porocarcinome eccrine.

INTRODUCTION: Eccrine sweat gland carcinoma, which belongs to the eccrine sweat gland carcinoma family, is a rare malignancy of the skin with a potential aggressive growth and metastatic spread. EXEGESIS: We report here a case of malignant eccrine poroma arising on the upper leg, with widespread pulmonary metastases. CONCLUSION: A brief synopsis of the pathological and clinical aspects of eccrine sweat gland carcinoma is presented with the currently available therapies.

[Hepatic ischemia and hypophyseal macroadenoma]. / Ischémie hépatique et adénome macro-hypophysaire.

We report the first case of recurrent hepatitis secondary to a pituitary macroadenoma in a 55-year old man. Liver ischemia is thought to be the main consequence of episodes of acute adrenal insufficiency. Sudden acute adrenal insufficiency was due to enlargement of the sella content secondary to several microhemorrhages in the macroadenoma.

[Mediastinoscopy in the case of recurrent uveitis]. / La médiastinoscopie au secours d'une uvéite traînante.

INTRODUCTION: The authors report the case of a patient who presented for 4 years recurrent anterior uveitis accompanied by asymptomatic tuberculous mediastinal lymphadenitis. EXEGESIS: CT scan of the chest showed the existence of mediastinal lymphadenopathy (< 1 cm). Mediastinoscopy with biopsy of the right laterotracheal lymph node was performed. The culture was positive for Mycobacterium tuberculosis, thus permitting the diagnosis of tuberculosis. CONCLUSION: This case report stresses the advantage of extensive etiological assessment when faced with unexplained uveitis; particularly it emphasizes the importance of investigating potential tuberculosis. The existence of granulomatous uveitis, a positive skin test, the ethnic origin, and mostly results of chest CT scan, were the rationale for the use of mediastinoscopy with lymph node biopsy to help guide diagnosis.
