Infective endocarditis due to Citrobacter koseri in an immunocompetent adult.

Citrobacter koseri (formerly Citrobacter diversus) is a motile gram-negative bacillus usually arising from urinary and gastrointestinal tracts. C. koseri rarely causes infection in immunocompetent patients and, thus far, has been considered an opportunistic pathogen. We report on a 30-year-old man, with no medical past, hospitalized for infective aortic endocarditis due to C. koseri. Four weeks of antibiotherapy led to a full recovery for this patient. However, this case is unusual, as previous history and 1 year of follow-up showed no features of intercurrent immunosuppression. Microbiological diagnosis was based on using 16S rRNA gene sequencing.

Lactic acidosis in Gabonese children with severe malaria is unrelated to dehydration.

BACKGROUND: Hyperlactatemia is an important and common complication of severe malaria. We investigated changes in fluid compartment volumes in patients with severe malaria and control patients with the use of bioimpedence analysis. METHODS: We estimated extracellular water and total body water volumes in a total of 180 children: 56 with severe malaria, 94 with moderate malaria, 24 with respiratory tract infection, and 6 with severe diarrhea. RESULTS: There was a mean (+/-SD) decrease in total body water volume of 17+/-24 mL/kg (or 3% of total body water volume) in patients with severe malaria. This compares with a mean (+/-SD) decrease in total body water volume of 33+/-28 mL/kg (or 6% of total body water volume) in patients with severe diarrhea. There was no increase in extracellular water volume in patients with severe malaria, suggesting no significant intravascular volume depletion in patients with severe malaria. There was no relationship between lactatemia and any changes in fluid compartment volumes. CONCLUSIONS: The changes in fluid volumes that were observed are unlikely to be of physiological significance in the pathophysiology of severe malaria.

Impact of systemic sclerosis on occupational and professional activity with attention to patients with digital ulcers.

OBJECTIVE: To evaluate the impact of systemic sclerosis (SSc; scleroderma) and digital ulcers (DUs) on daily living and professional activities. METHODS: We prospectively evaluated 189 SSc patients for employment status and disability during meetings of the French SSc patient association (n=86, 45.5%) or during hospitalization (n=103, 54.5%). RESULTS: Seventy-eight (41.2%) patients had diffuse SSc. The mean±SD age was 54±13 years, and the mean±SD disease duration was 9.3±8.4 years at the time of evaluation. Sixty (31.7%) patients had at least one DU. Assessed using the Health Assessment Questionnaire (mean±SD 1.12±0.79 versus 1.39±0.84; P=0.001), the Cochin Hand Function Scale (mean±SD 20.2±18.3 versus 27.8±19.1; P<0.0001), and the Hospital Anxiety Scale (mean±SD 9.9±5 versus 8.5±4.2; P=0.04), global disability, hand disability, and anxiety, respectively, were significantly higher in patients with DUs than in others. Most patients reported a limitation in daily activities related to SSc, as assessed by a daily activity limitation scale (mean±SD 4.4±2.9) and an increased need for help in the home. Patients reported needing mean±SD 4±13.5 hours per month of paid household help related to SSc and mean±SD 1.5±10 hours per month related to DUs, with significant differences between patients with or without DUs (P=0.004). Among the 113 patients in the workforce, 67 (59.3%) were employed, 42 (37.2%) were employed full time, 36 (31.8%) received full disability pension, and 27 (23.9%) were on sick leave, with no difference between patients with or without DUs. CONCLUSION: SSc has a significant impact on activities of daily living and work disability. The need for external home help and disability are increased for those patients with DUs.

Epileptiform seizures revealing neurocysticercosis: report of two clinical cases in Libreville, Gabon.

Neurocysticercosis (NCC) is the most common helminth infection of the central nervous system. It is caused by the larval form of the tapeworm Taenia solium and is increasingly recognized as a major cause of neurologic disease worldwide. Epilepsy is the usual mode of revelation. Neuroimaging, including computed tomography and magnetic resonance imaging, combined with serodiagnostic techniques have led to this increased recognition. We report on two cases (one co-infected with the HIV) of NCC diagnosed in 2006 and 2008 at the Omar Bongo Ondimba Army Teaching Hospital. New-onset epilepsy revealed the two cases. Medical treatment with albendazole, anti-epileptic drugs and corticosteroids led to full recovery. NCC should be considered in tropical countries as a leading cause of epilepsy. Moreover, NCC should be included in the differential diagnosis of neurologic infections in HIV patients in endemic populations.
