Uncomplicated urinary tract infection (UTI) has become surprisingly complicated to treat in recent years because of growing prevalence of microbial resistance to trimethoprim-sulfamethoxazole (TMP-SMX) and quinolones. Many experts now propose resurrection of the venerable antibiotic nitrofurantoin as a first-line treatment for uncomplicated cystitis.
Added On : 17th August 201111% of patients had symptomatic arrhythmias.
The yield of Holter monitoring in patients with syncope depends on clinical characteristics and patient age, which affect pretest probability of an arrhythmic cause. In this study, Swiss researchers examined the diagnostic yield of 24-hour Holter monitoring in 475 consecutive patients (age, >80; 13% ?90) with syncope. Patients whose initial evaluations revealed obvious causes of syncope (e.g., orthostatic hypotension, diagnostic 12-lead electrocardiogram [ECG] finding) and those with previously implanted pacemakers were excluded. At baseline, half the patients had known structural heart disease.

Infectious agents trigger liver, cervical, gastric, and nasopharyngeal carcinomas, as well as some lymphomas. Two research groups, one based in British Columbia and one in Massachusetts, now independently report a strong association between Fusobacterium species and colorectal cancer.
