Host DNA can interfere with detection of Borrelia burgdorferi in skin biopsy specimens by PCR.

It is demonstrated that a diagnostic PCR for Borrelia burgdorferi can be inhibited in the presence of more than 500 ng of host (monkey skin) DNA. The inhibitor is the host DNA itself. An acceptable value for analytical sensitivity can be obtained by diluting the skin-B. burgdorferi proteinase K lysate to a level below the inhibitory concentration of the host DNA. Dilution of the lysate may obviate the need for further DNA purification.

[Analysis of the results with Rigiscan in 93 impotent patients].

OBJECTIVE: This study was undertaken to evaluate the performance of the Rigiscan in the diagnosis of sexual impotence. METHODS: Erectile nocturnal activity was evaluated by Rigiscan in 93 patients consulting for impotence; mean age 56.8 years. Diagnosis and treatment were performed between October, 1990 and May, 1992. Follow up is currently ongoing. RESULTS: 95.1% of the patients with normal recordings had no organic pathology, and 80% of these recordings were observed on the first night of the study. In ruling out organic pathology, the Rigiscan did not have a higher specificity than the report of early morning erection (EME) by the patients (p > 0.05). Seventy three percent of the pathological results on the Rigiscan studies were associated to organic pathology. This test showed a higher sensitivity than the absence of EME (p < 0.01). Although no pathognomonic diagnostic pattern was found, a flat pattern and uncoupling were highly suggestive of organic disorders. CONCLUSIONS: The Rigiscan is a useful diagnostic tool, especially in patients reporting no EME. Furthermore, the Rigiscan was able to detect almost all the patients with organic pathology.

Synergy characterization for Enterococcus faecalis strains displaying moderately high-level gentamicin and streptomycin resistance.

Synergy of 14 Enterococcus faecalis strains displaying moderately high-level aminoglycoside resistance (MICs, 500 and 256 to 1,000 micrograms/ml for gentamicin and streptomycin, respectively) was characterized by time-kill studies. All strains proved resistant to penicillin plus the respective aminoglycoside. Strains with moderately high-level aminoglycoside resistance should be considered to exhibit high-level resistance in severe infections.

Abscess caused by vancomycin-resistant Lactobacillus confusus.

Several isolates of vancomycin-resistant Lactobacillus confusus from human sources have been described, but to our knowledge, no well-documented infection attributable to this organism has been published. A thumb abscess caused by this bacterium in a healthy 49-year-old male is reported here. He was successfully treated by surgical drainage and cephalothin.
