Mycobacterium celatum infection in two HIV-infected patients treated prophylactically with rifabutin.

Mycobacterium celatum is a recently described slow-growing species. It was identified on the basis of genomic sequencing that differentiates three types. The present report describes two cases of Mycobacterium celatum type 1 infection in patients with AIDS.

Clinical and bacteriologic impact of rifabutin prophylaxis for Mycobacterium avium complex infection in patients with human immunodeficiency virus infection.

We conducted a prospective observational study to determine the feasibility and impact of rifabutin prophylaxis (300 mg daily) for human immunodeficiency virus-infected patients whose CD4 cell counts were <100/mm3. Three hundred seventy-one patients (65.2% of all patients with CD4 cell counts of <100/mm3 [mean +/- SD, 30 +/- 25/mm3]) received rifabutin prophylaxis for a mean duration +/- SD of 35.

[Does laparoscopy increase the bacteriological risk of appendectomy? Results of a randomized prospective study].

Objective: The authors compare the risk of bacteraemia in open and laparoscopic appendectomy in a prospective randomized study.

Methods: 35 patients with a presumptive diagnosis of acute appendicitis were randomized to have conventional open or laparoscopic surgical procedures. Before randomization, patients signed a consent form to participate in the study.
