Diabetes in patients with pasteurellosis.

From 1991 to 2003, 20 patients with pasteurellosis were admitted to our unit, of whom 2 died. They presented with cellulitis (n = 14), arthritis (n = 6), pneumonia (n = 3), subcutaneous abscess (n = 3), bursitis (n = 2), meningitis, otitis, sinusitis and uveitis. Underlying diseases included diabetes (n = 6) and malignancy (n = 5). Diabetes could be a predisposing condition for pasteurellosis.

Imported Crimean-Congo hemorrhagic Fever.

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease that may also be transmitted through person-to-person transmission by exposure to infected body fluids. Despite its wide geographic distribution in animals, CCHF virus is rarely associated with recognized human diseases. We report the first case of imported CCHF in France.

Mitochondrial abnormalities in HIV-infected lipoatrophic patients treated with antiretroviral agents.

BACKGROUND: Lipodystrophy is now widely described in HIV infected patients under antiretroviral regimen with important psychological impact. But physiopathology of loss of fat mass is still debated and the role of mitochondrial impairment is not clearly defined. OBJECTIVE: To correlate clinical lipoatrophy (LA) in HIV patients with long-term treatment by nucleoside reverse transcriptase inhibitors (NRTIs) and muscular impairment related to mitochondrial dysfunction. METHODS: Ten consecutive patients with clinical LA and 10 nonlipodystrophic (NLD) individuals on antiretroviral therapy were included. Patients underwent the following investigations: dual-energy x-ray absorptiometry (DEXA) scanning and lactate kinetics during standardized exercise. The mitochondrial respiratory complex activity (III and IV) and histoenzymatic abnormalities (classified as none, mild, or severe) were evaluated on muscle tissue obtained by biopsy in deltoid muscle. RESULTS: Mean NRTI exposure was longer in the LA group than in the NLD group (81 +/- 30 months vs. 59 +/- 15 months), but mean protease inhibitor exposure was identical in both groups. Mean fat mass distribution for leg in the LA and NLD groups was 860 +/- 381 g versus 1895 +/- 999 g, respectively. The lactic acidosis threshold during exercise was reached in the LA group at lower workloads (mean: 45 +/- 17 W in the LA group vs. 68 +/- 11 W in the NLD group), and maximum power output exercise was restricted in LA patients (mean: 115 +/- 30 W vs. 153 +/- 28 W). Total complex activities in muscular tissue were lower in LA patients: the median (range) for complex III was 67 (1-128) versus 112 (28-143), and the median (range) for complex IV was 28 (1-70) versus 42 (1-75). Six patients had severe histoenzymatic abnormalities in the LA group versus none in the NLD group. CONCLUSION: Clinical LA, confirmed by DEXA, in long-term NRTI-treated patients was associated with muscular mitochondrial dysfunction as shown by rapid lactic acidemia increase, impairment of respiratory chain activity for complexes III and IV, and mitochondrial histoenzymatic abnormalities.

Vertebral osteomyelitis presenting as exudative pleural effusion.

The most common causes of exudative pleural effusion are tuberculosis, malignancy, and pneumonia. However, exudative pleural effusion may also reveal contiguous infectious processes including cholecystitis, subphrenic pus collection, and thoracic vertebral osteomyelitis. In the latter, the diagnosis is usually delayed. We report two cases of thoracic vertebral osteomyelitis presenting as exudative pleural effusion for which the diagnosis could be suspected by a careful analysis of the thoracic imaging studies performed on admission.

Campylobacter fetus septic arthritis revealing a malignancy.

Campylobacter fetus is a rare cause of bone and joint infection. We report a new case in a patient who also had endocarditis due to the same organism. This type of infection usually occurs in immunocompromised hosts. Investigations in our patient found a cancer of the prostate.

Treatment of latent syphilis in HIV-infected patients with 10 d of benzylpenicillin G benethamine: a prospective study in Maputo, Mozambique.

Neurosyphilis has been reported in HIV-infected patients previously treated with penicillin G benzathine, which does not achieve treponemicidal levels in cerebrospinal fluid. Therapy combining benzylpenicillin G and its repository form benzylpenicillin G benethamine could be a potentially effective alternative enhanced regimen for treating latent syphilis in HIV-infected patients because peak serum and cerebrospinal fluid concentrations would be achieved early post-administration by the former molecule and sustained for 24 h due to the prolonged half-life of the latter. In this study, 23 asymptomatic HIV and Treponema pallidum co-infected patients received 10 d of combined therapy (2 M IU intramuscular once daily) and were followed up at 3, 6 and 12 months. None experienced side effects or clinical symptoms. Of the 18 patients who were evaluated 1 y later, 8 (44.4%) exhibited serological treatment failure, defined as a positive serum rapid plasma reagin test. In conclusion, a 10-d regimen combining penicillin G and penicillin G benethamine seems to be of no benefit compared to currently recommended treatment.
