[Antibiotic prophylaxis in urology]. / Antibiotická profylaxe v urologii.

Antibiotic prophylaxis is an important measure aimed at reduction of infectious complications after urologic procedures. The goal of this prospective study is assessment of the efficacy, safety and cost of short-time antibiotic prophylaxis before planned urologic surgery. Uncomplicated cystoscopy, urodynamic examination and ESWL were performed without antibiotic prophylaxis. Oral quinolones were effective in prostate biopsy. In open, laparoscopic or endoscopic surgery intravenous prophylaxis by cephalosporins had excellent efficacy. All types of prophylaxes were very safe and without adverse effects, and could be applied at low economic cost.

[Peroperative diagnostics of acute bowel ischemia using ultraviolet light and fluorescein dye]. / Peroperacní diagnostika ischemie streva za pouzití fluoresceinu a ultrafialového svetla.

Acute bowel ischemia continues to have a high mortality rate. The main factor related to this poor outcome is considered to be the delay in diagnosis. The ability to detect ischemia early and to assess the extent of bowel involvement, are the most important aspects of successful treatment. The combination of ultraviolet (UV) light and fluorescein dye would be considered a simple, reliable and technically easy procedure for diagnosis of intestinal ischemia. The method can be used both for laparotomy when the source of UV light is a Wood's lamp as well for laparoscopy when the optical filters are placed to the light source of laparoscopic set to produce UV light. Present clinical experience shows that the method is precise, objective and accessible and that it gives a greater amount of independence to the surgeon allowing him to make the diagnosis of intestinal ischemia without having to rely on the assistance of other specialists.

[Urologic surgery in diabetes]. / Urologické výkony u diabetika.

INTRODUCTION: The diabetes mellitus is risk factor for urologic surgery. The best prevention of complications is excellent compensation of diabetes, appropriated management of anesthesia and good post surgery care. The diabetes is etiologic risk factor many urologic diseases including malignant. UROLOGIC SURGERY: The diabetes is intensively evaluated in uro-oncology and it seems that renal cell carcinoma and bladder cancer incidence is higher in diabetic patients. The link between prostate cancer and diabetes is not clear, yet. The behavior of this cancer is more aggressive and it has worse prognosis. The diabetes is risk etiologic factor for urolithiasis and benign prostatic hyperplasia. Immunodeficiency combined with diabetes has negative impact for urinary tract infection including most serious as emphysematous pyelonephritis or Fournier gangrene external genitalia. CONCLUSION: The accurate compensation of the diabetes is basic condition good results of urologic surgery in diabetics. The diabetes mellitus and obesity will be evaluated as risk factors many diseases of kidneys and whole urologic apparatus especially malignant.

The frequency of alleles of the Pro12Ala polymorphism in PPARgamma2 is different between healthy controls and patients with type 2 diabetes.

The aim of this initial case-control study was to determine the association between common Pro12Ala polymorphism in the PPARgamma2 gene and type 2 diabetes in the Czech Republic. Furthermore, the effect of this polymorphism on phenotypic characteristics and on levels of lipids (total cholesterol, HDL-cholesterol, LDL-cholesterol and triglycerides) was studied. One hundred thirty-three patients with type 2 diabetes and 97 control subjects were investigated. PCR and RFLP analysis were used for identification of individual genotypes. In the group of patients, three samples (2.26%) were identified as homozygous for the Ala/Ala genotype and 99 samples (74.44%) were homozygotes for the Pro/Pro genotype. Thirty-one samples (23.31%) were identified as Pro12Ala heterozygous. In the control group, six samples (6.19%) were homozygous for the Ala/Ala genotype and 61 samples (62.89%) were homozygotes for the Pro/Pro genotype. Thirty samples (30.93%) were identified as Pro12Ala heterozygous. The allele frequency for the Ala allele was lower in the type 2 diabetic group than in the control group (13.91% vs. 21.43%, P = 0.022). There was no difference (at P < 0.05) between the phenotypic characteristics (BMI, sex) studied in the group of patients according to the Pro12Ala genotype. There was no significant effect of the Pro12Ala polymorphism on lipid levels.
