[Obesity, diabetes mellitus, and gas gangrene: a major therapeutic challenge].

Soft tissue infections are uncommon but prognosis is severe (20 to 50%). Management consists in surgical debridement, antibiotic therapy against anaerobic and aerobic bacteria, and appropriate intensive care. When available, hyperbaric oxygen therapy is an integral part of the treatment. We report the case of 56-year-old female patient with diabetes (150 kg) was hospitalized in our unit a few days after surgical treatment of a buttocks abscess for clinical signs of peripheral gas gangrene. Surgical exploration showed necrotizing soft tissue infection with fasciitis. Adequate therapy using anti

[Fever and lung abscesses in anorexia nervosa after infusion therapy].

A 26 year old female patient was admitted to our hospital because of septic temperatures and chills. In the patient's history renal insufficiency has been known for several years due to agenesia of the right and pyelonephritic renal congestion of the left kidney. Long lasting anorexia nervosa had been treated by psychotherapeutical interventions for years and when failing it necessitated repeated intravenous nutrition by central venous lines. The prominent symptom of the intravenously treated young woman was fever up to 39.7 degrees C and pneumonia, which was considered by the first treating c

Burkholderia ubonensis Meropenem Resistance: Insights into Distinct Properties of Class A β-Lactamases in Burkholderia cepacia Complex and Burkholderia pseudomallei Complex Bacteria.

Burkholderia pseudomallei, the founding member of the B. pseudomallei complex (Bpc), is a biothreat agent and causes melioidosis, a disease whose treatment mainly relies on ceftazidime and meropenem. The concern is that B. pseudomallei could enhance its drug resistance repertoire by the acquisition of DNA from resistant near-neighbor species. Burkholderia ubonensis, a member of the B. cepacia complex (Bcc), is commonly coisolated from environments where B. pseudomallei is present. Unlike B. pseudomallei, in which significant primary carbapenem resistance is rare, it is not uncommon in B. ubone…

Extended-spectrum plasmid-mediated beta-lactamases.

Extended-spectrum beta-lactamases (ESBLs) are mutant enzymes which derive from TEM or SHV (class A) enzymes. They confer variable levels of resistance to cefotaxime, ceftazidime and other broad-spectrum cephalosporins and to monobactams such as aztreonam but have no detectable activity against cephamycins and carbapenems. Recently, new plasmid-mediated ESBLs, not derived from TEM or SHV enzymes but related to cephalosporinases of Enterobacteriaceae (class C enzymes), that confer resistance to all cephalosporins including cephamycins, have been reported. However, to date there have been no repo…

Cloning and sequence of the gene encoding a cefotaxime-hydrolyzing class A beta-lactamase isolated from Escherichia coli.

Escherichia coli TUH12191, which is resistant to piperacillin, cefazolin, cefotiam, ceftizoxime, cefuzonam, and aztreonam but is susceptible to cefoxitin, latamoxef, flomoxef, and imipenem, was isolated from the urine of a patient treated with beta-lactam antibiotics. The beta-lactamase (Toho-1) purified from the bacteria had a pI of 7.8, had a molecular weight of about 29,000, and hydrolyzed beta-lactam antibiotics such as penicillin G, ampicillin, oxacillin, carbenicillin, piperacillin, cephalothin, cefoxitin, cefotaxime, ceftazidime, and aztreonam. Toho-1 was markedly inhibited by beta-lact…

[Basic and clinical studies on biapenem (L-627) in obstetrics and gynecology].

UNLABELLED: We investigated biapenem (BIPM, L-627) a newly carbapenem antibiotic, for its antibacterial activity, tissue penetration, clinical efficacy and bacteriological effect in obstetric and gynecological infections, and obtained the following results. 1. Antibacterial activity: MICs of L-627 against 149 strains isolated from 80 patients in this clinical trial were examined and compared with those of imipenem (IPM) and ceftazidime (CAZ). The MIC50 and MIC90 of L-627 against the isolates were 0.2 and 12.5 micrograms/ml, respectively. Those of IPM were 0.2 and 6.25 micrograms/ml, respective…
