[Scrotal pain and Henoch-Schönlein purpura]. / Skrotal smerte og Henoch-Schönleins purpura.

An acute scrotum is a potential urologic emergency and requires urgent evaluation in order to rule out conditions that need immediate surgical management. The most important condition to rule out is torsion of the testis. In cases of less emergency, a wide variety of differentials may be considered. Scrotal pain or swelling may occur in 10 to 15% of boys with Henoch-Schönlein purpura. We present the case of a 19-year-old boy who had intermittent scrotal pain of two weeks' duration with acute exacerbation prior to admission. The clinical examination gave no specific results. A regular and Doppler sonographic scan showed no evidence of testicular affection. The patient was observed in hospital. Two years earlier he had present with abdominal cramps, rectal bleeding, duodenitis, proteinuria and a purpuric rash, suggestive of Henoch-Schönlein purpura; IgA-nephritis was proven after a renal biopsy. As all other differentials had been ruled out, we concluded that Henoch-Schönlein syndrome was the cause of the recurrent scrotal pain in our patient.

Radiation dose escalation combined with hormone therapy improves outcome in localised prostate cancer.

We present the impact of systematic radiation dose escalation from 64 Gy to 66 Gy to 70 Gy on the outcome after radiation therapy (RT) alone or combined with hormonal treatment (HT) in a series of 494 consecutive localised prostate cancer patients treated during 1990-1999. Prognostic factors for prostate-specific antigen (PSA) failure, overall survival (OS) and prostate cancer specific survival (CSS) were investigated using multivariate analysis. T stage, pre-treatment PSA, grade, radiation dose and HT were found to be independent predictors of PSA failure. T stage, grade and HT were also independent predictors of both OS and CSS, while radiation dose was a significant predictor for OS and indicated a trend (p = 0.07) for CSS. A dose of 70 Gy combined with hormonal treatment improves PSA failure free survival and survival in localised prostate cancer compared with doses of 64-66 Gy.

Reproducibility and prognostic variability of grade and lamina propria invasion in stages Ta, T1 urothelial carcinoma of the bladder.

PURPOSE: We assessed the reproducibility and prognostic variability of grade and lamina propria invasion in stages Ta, T1 urothelial carcinoma of the bladder. MATERIALS AND METHODS: A total of 130 consecutive stages Ta, T1 urothelial carcinomas routinely diagnosed by 15 pathologists (original diagnosis) were reviewed by 3 independent experienced pathologists using 1999 WHO criteria (diagnoses 1 to 3 and reviewer consensus diagnosis). Interreviewer disagreement cases were blindly reviewed again. Each remaining disagreement case was discussed in a multihead microscope session to attempt to solve remaining disagreements. In cases of continuing disagreement the majority diagnosis on stage and grade was considered the consensus diagnosis. Stage progression at followup was the dependent variable. Stage progression-free Kaplan-Meier survival curves and hazard ratios of each stage and grade diagnosis were calculated and prognostic variability was determined. RESULTS: There was complete interobserver agreement on stage and grade among reviewers in 80% and 59% of cases, while it was 87.7% and 75.4%, respectively, after the second review. More than 1 grade difference occurred in 1.5% of cases (0% after the second review). The consensus and original diagnoses agreed on stage and grade in 68.5% and 62.3% of cases, respectively. Assignment of individual cases to 1 category of the 1999 WHO classification per reviewer varied considerably. The incidence of cases classified as stage T1 grade 3 by the reviewers was between 12.3% and 18.9% (average 14.1%). Consensus diagnosis grade had the strongest prognostic value (HR 68.8, range 8.9 to 528.0). Of the 63 original diagnoses of stage T1 tumors the consensus diagnosis down staged 35 (55.6%) to Ta and up staged 8 (12.7%) to T2-3. Progression was more common in the 20 consensus diagnosis stage T1 cases (5 or 25%) than in the 55 original diagnosis stage T1 cases (11 or 20%). Original diagnosis stage T1 tumors that were down staged by the consensus diagnosis showed less progression than consensus diagnosis confirmed stage T1 tumors (17% versus 25%). The prognostically worst subgroup (T1 grade 3) also showed considerable prognostic variation among reviewers (28% to 76% at 5 years of followup), in that the consensus diagnosis again had the highest prognostic significance (HR 3.5, range 1.2 to 10.2). At the end of the study all pathologists expressed that they were regularly uncertain about stage and grade assessment in an individual case in a considerable percent of all cases. CONCLUSIONS: Observer prognostic variability in staging and grading is considerable with potentially strong implications for patients. Interobserver variation did not decrease using the new 1999 WHO grading classification.

DNA cytometric features in biopsies of TaT1 urothelial cell cancer predict recurrence and stage progression more accurately than stage, grade, or treatment modality.

OBJECTIVES: To compare retrospectively the predictive value for recurrence and stage progression of DNA ploidy and S-phase fraction by flow cytometry and highly automated ultrafast image cytometry (ICM) in biopsies of TaT1 urothelial cell carcinomas (UCCs) of the urinary bladder with stage, grade, other pathologic features, and treatment. METHODS: Three experienced pathologists reviewed the stage and grade of 228 UCCs; 193 (85%) consensus cases were analyzed further. We had enough material for single-cell suspensions for both flow cytometry and ICM in 183 cases (94.8%). The 2001 European Society for Analytical Cellular Pathology standards for DNA ICM were followed. The predictive value of DNA features, classic prognosticators (stage, grade, carcinoma in situ, multicentricity), and treatment modality for recurrence and stage progression were analyzed with univariate (Kaplan-Meier) survival and multivariate (Cox model) regression analysis. Ta and T1 cases were analyzed separately. RESULTS: Of the 228 cases, 88 (51.5%) recurred and 13 (7.6%) progressed. On univariate analysis, most of the DNA features studied were statistically significant. Treatment modality and grade were only prognostic for progression (not for recurrence) and only in Ta cases. On multivariate analysis, DNA ICM features performed best; the strongest recurrence predictor for Ta UCC was a DNA index (DI) of 1.0 versus all others, and for T1 UCC, a DI of less than 1.3 versus 1.3 or greater. The best stage progression predictor for Ta UCCs was a DI of 1.0 plus an S-phase fraction of less than 10%, and for T1 UCCs, a DI of less than 1.3 versus 1.3 or greater. With multivariate analysis, sex, age, grade, carcinoma in situ, multicentricity, and treatment modality were excluded once the DNA ICM features were selected. CONCLUSIONS: DNA image cytometric features predict recurrence and stage progression in TaT1 UCC biopsies more accurately than classic prognostic factors, independent of treatment modality.
