The influence of diabetes mellitus on the spectrum of uropathogens and the antimicrobial resistance in elderly adult patients with urinary tract infection.

Background: The role of Diabetes mellitus (DM) in the etiology and in the antimicrobial resistance of uropathogens in patients with urinary tract infection has not been well clarified. For this reason we have evaluated the spectrum of uropathogens and the profile of antibiotic resistance in both diabetic and non diabetic patients with asymptomatic urinary tract infection (UTI).

Methods: Urinary isolates and their patterns of susceptibility to the antimicrobials were evaluated in 346 diabetics (229 females and 117 males) and 975 non diabetics (679 females and 296 males) who were screened for significant bacteriuria (> or = 10(5) CFU/mL urine).

Epidemiological and clinical features of 139 patients with tuberculosis at a teaching hospital in Italy (Pisa, 1996-2000).

In order to describe epidemiologic and clinical features of patients with tuberculosis (TB) identified recently in the hospital of Pisa (Tuscany, Italy), a retrospective study of all cases of TB notified to the Local Public Health Service during January 1996-December 2000 was performed. The diagnosis of TB was made following the criteria of the WHO. A total of 139 patients affected by TB were identified.

Asymptomatic bacteriuria in women with diabetes: influence of metabolic control.

We screened 228 women with diabetes for bacteriuria during the period of January 1997 through December 2000 at Pisa General Hospital (Pisa, Italy). A control group of 146 women without diabetes was also evaluated. The frequency of significant bacteriuria was 17.
