Invasive rhino-orbital-cerebral aspergillosis in an immunocompetent patient.

INTRODUCTION: Rhino-orbital-aspergillosis (ROA) is a rare but serious disease in immunocompetent patients. Diagnosis is often delayed due to the absence of specific clinical symptoms. We describe the case of a patient who presented initially with ROA which spread progressively to the right ethmoid-sphenoid sinuses and then to the brain. OBSERVATION: A 61-year-old patient with a history of well-controlled diabetes presented with a sudden severe decrease in right visual acuity. Cerebral MRI showed the presence of an infiltrate in the right orbital apex extending to the homolateral cavernous sinus without any cerebral involvement. A diagnosis of right orbital myositis was made and corticosteroid therapy was started. His symptoms worsened progressively leading to quasi-blindness. A new MRI showed the development of right sphenoid-ethmoid osteolytic lesions. A fungal aetiology was suspected and tests for fungal biomarkers found a ß-(1-3)-D-glucan level of 99pg/ml but negative galactomannan. An ethmoid biopsy was performed for histological and mycological investigations, including the detection of Aspergillus DNA by qPCR. qPCR was positive and culture resulted in the isolation of multi-sensitive Aspergillus fumigatus. Treatment was initiated with voriconazole. Due to persistence of blindness and the appearance of a lesion extending to the right frontal lobe, surgical excision was performed followed by antifungal treatment for a total duration of 1year. The patient is currently stable, but has persistence of blindness in the right eye. CONCLUSION: Invasive ROA is a rare but serious disease in immunocompetent patients which should be evoked in the differential diagnosis of a tumour or vasculitis. Early diagnosis is essential for optimal management.

Cefoxitin: An alternative to carbapenems in urinary tract infections due to extended-spectrum beta-lactamase-producing Enterobacteriaceae.

BACKGROUND AND OBJECTIVES: Infections caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) have become a major public health issue worldwide. Cefoxitin is a second-generation cephalosporin and is associated with a strong in vitro activity against ESBL. PATIENTS AND METHODS: We conducted a prospective monocentric cohort study from 2012 to 2015 to evaluate the clinical efficacy and safety of cefoxitin in 15 patients treated for urinary tract infection (UTI) caused by ESBL-E, without any severity criteria. RESULTS: We included 15 patients; 11 were male patients with defined risk factors for ESBL-E. Ten patients presented with male UTI, three with pyelonephritis, and two with cystitis. Escherichia coli was the predominant pathogen. All patients had a positive outcome with a good tolerance (a skin rash without any sign of severity was observed in one patient). Microbiological cure was obtained in 9 patients out of 10 at the end of treatment. CONCLUSION: Cefoxitin is an alternative treatment to carbapenems for urinary tract infections caused by ESBL-producing Enterobacteriaceae.

[MPO-ANCA related vasculitis presenting as chronic iron deficiency anemia due to paucisymptomatic intra-alveolar haemorrhage]. / Micropolyangéite révélée par une anémie d'évolution chronique secondaire à une hémorragie intra-alvéolaire paucisymptomatique: à propos d'un cas.

INTRODUCTION: An alveolar haemorrhage occurs in 12 to 29% during microscopic polyangeitis and can reveal this disease. EXEGESIS: We report the case of a fifteen years old female patient with a microscopic polyangeitis which was diagnosed during the investigation of a chronic anemia with chronic asymptomatic alveolar haemorrhage and extracapillary glomerulonephritis with antineutrophil cytoplasmic antibodies positive (anti-myeloperoxydase antibodies). The good tolerance of alveolar haemorrhage is usual for children, particularly in idiopathic pulmonary haemorrhage but is exeptionnal for adults. According to some studies, thirty percent of idiopathic pulmonary haemorrhage goes to auto-immune disease. CONCLUSION: This observation shows that complementary pulmonary investigations are necessary in chronic anemia when gynaecologic and digestive investigations are negative and that auto-immune investigations are judicious in the survey of idiopathic pulmonary haemorrhage.
