Comparative evaluation of agar dilution and broth microdilution methods for antibiotic susceptibility testing of Helicobacter cinaedi.

The aim of this study was to establish a broth microdilution method for antimicrobial susceptibility testing of Helicobacter cinaedi and to assess the prevalence and mechanisms of fluoroquinolone resistance in Japanese clinical isolates. A broth microdilution method using modified Levinthal broth was developed and compared with the agar dilution method for testing susceptibility to ampicillin, gentamicin, tetracycline and ciprofloxacin. The minimum inhibitory concentrations obtained by these two methods were almost the same for all the antibiotics tested, demonstrating the broth microdilution method to be a suitable and reliable technique for antimicrobial susceptibility testing.

[A multicenter study of cardiac events and anesthetic management of patients with ischemic heart diseases for noncardiac surgery--a follow-up report].

We have conducted a joint research project to investigate the incidence of ischemic heart disease in patients for noncardiac surgery and to define the risk of perioperative cardiac complications in these patients. From September to November 1997 we had 7288 patients scheduled to undergo noncardiac surgery in the 8 departments of anesthesiology. Of these patients, 228 (3.

[Three case reports of the use of stellate ganglion block for the climacteric psychosis].

There are many reports of the use of stellate ganglion block (SGB) for the climacteric psychosis, which is considered to be sympathicotonic response to stress. We experienced three cases of the SGB therapy for the climacteric psychosis. We performed SGB three times per week by 1% lidocaine 5 ml, and observed improvements of the symptoms after doing SGB for five times.
