Preoperative and postoperative staging in endometrial cancer - a prospective study.

OBJECTIVE: The aim of this study was to determine how often changes the stage of the tumour in definitive histology against preoperative clinical stage in patient cohort with diagnosed endometrial cancer. METHODS: We evaluated prospectively a cohort of 166 patients with endometrial cancer. They all underwent abdominal hysterectomy, bilateral salpingo-oophorectomy, sentinel lymph node biopsy. Patients with high-risk tumours also pelvic lymfadenectomy. We collected data of preoperative diagnostic biopsy and postoperative definitive histology. The data were statistically processed. RESULTS: Detection of sentinel lymph node was successful in 71.1%, bilateral successful detection was in 40.6%. Discrepancy of tumour grade between preoperative biopsy and definitive histology was generally 31.4%. Upgrading of the tumour was in 22 (14.4%) cases, downgrading in 26 (17%) cases. Upgrade from low-risk to high-risk group of tumours was noticed in eight cases. Histopathological tumour type changed in 6.6%, 4.6% moved to histopathologic high-risk group. The tumour stage changed in definite histology in 57.3%, in 19.2% of cases moved from stage low/intermediate-risk group to intermediate-high/high-risk disease group. CONCLUSION: Correct assessment of preoperative clinical stage and histological grade of endometrial cancer is burdened with a high inaccuracy rate. A lot of cases is up-staged after surgical staging and moved to intermediate-high/high-risk disease group. Results confirm the importance of oncogynaecologic centre II. evaluation of histopathology findings from diagnostic biopsies made in referring hospitals. Sentinel lymph node biopsy should be performed even in clinically low/intermediate-risk disease group.

Hospital size, remoteness and stroke outcome.

INTRODUCTION: Previous studies have shown an association between number of stroke admissions and outcomes. Small hospitals often support more remote areas and we studied national data to determine if an association exists between hospital remoteness and stroke care. METHODS: Data from the Irish National Audit of Stroke (INAS) on average stroke admissions, adjusted mortality for ischaemic stroke, thrombolysis rate and proportion with door to needle (DTN) ≤45 min were analysed. Hospital remoteness was quantified by distance to the next hospital, nearest neurointerventional centre and location within 10 km of the national motorway network. RESULTS: Data for 23 of 24 stroke services were evaluated. Median number of strokes admitted per year was 186 (range 84-497). Nine hospitals (39%) admitted ≥200 stroke patients per year (mean 332). Average adjusted mortality (7.0 vs. 7.3, P = 0.67 t-test), mean thrombolysis rate (12.1% vs. 9.2%, P = 0.09) and mean proportion of patients treated ≤45 min (40.4% vs. 31.3%, P = 0.2) did not differ significantly between higher and lower volume hospitals.Hospitals close to the motorway network (n = 15) had a higher mean thrombolysis rate (11.9% vs. 7.5%, P = 0.01 t-test) and proportion DTN ≤45 min (43.7-18.4%, P < 0.001).Number of stroke admissions did not correlate with mortality (r = 0.06, P = 0.78), DTN (r = 0.12, P = 0.95) or thrombolysis rate (r = 0.35, P = 0.20). Distance to next hospital correlated strongly negatively with DTN (r = -0.47, P = 0.02) and thrombolysis rate (-0.43, P = 0.04). CONCLUSION: Remoteness of hospitals is associated with worse measures of stroke outcome and management.

[Antibiotic resistance and adhesive properties of agents of catheter-associated infections of urinary tract].

The authors have investigated etiological structure, antibiotic resistance and adhesive properties of the agents of catheter-associated urinary tract infections (CAUTI) isolated from patients kept in the Department of Resuscitation and Intensive Care. It has been found that bacteria pathogens of CAUTI genus Enterococcus and their associations with other microorganisms dominated in species composition. Strains of enterococci had a high level of resistance to antimicrobial drugs studied except vancomycin and teicoplanin, which proved to be 100% sensitive strains. The vast majority of the investigated strains were characterized by medium to high adhesiveness.
