[Hyperbaric oxygen therapy adjunctive to surgical debridement in management of Fournier's gangrene: usefulness of a severity index score in predicting disease gravity and patient survival]. / Terapia de oxígeno hiperbárico complementaria al desbridamiento en el control de la gangrena de Fournier: utilidad de la puntuación de un índice de severidad en la predicción de la gravedad de la enfermedad y la supervivencia del paciente.

INTRODUCTION: Hyperbaric oxygen therapy (HBOT) concomitant to surgery has been reported to reduce Fournier's gangrene (FG) mortality compared to exclusive surgical debridement. Most report from centers with relatively few patients using only surgical procedure. To assess efficiency of aggressive debridement with adjunctive HBOT. To evaluate Fournier's gangrene severity score index (FGSI) predictive value. MATERIAL AND METHODS: 70 Fournier's gangrene (FG) treated by surgical debridement and HBOT. Data were evaluated physical examination findings, admission and final laboratory tests, surgical debridement extent, and antibiotic used. Patients had adjunctive (HBOT). FGSI, developed to assign a score describing the acuity of disease, was used. This index presents patients' vital signs, metabolic parameters (sodium, potassium, creatinine, and bicarbonate levels, and white blood cell count) and computes a score relating to the severity of disease at that time. Data were assessed according to whether the patient survived or died. All patients underwent surgical debridement. Wound debridement was regularly performed in the post operative period. RESULTS: Of 70 patients, 8 died (11.4%) and 62 survived (88.5%). Difference in age between survivors (median age, 50.0 yr) and non survivors (median age, 54.5 yr) was not significant (p=0.321). Median extent of body surface area involved in necrotizing process in patients who survived and did not survive was 2.4% and 4.9%, respectively (p=0.001). Except for albumin, no significant differences were found between survivors and nonsurvivors. Median admission FGSI scores for survivors and non survivors were 2.1±2.0 and 4.2±3.8, (p=0.331). CONCLUSION: FGSI score did not predict disease severity and the patient's survival. Metabolic aberrations, extent of disease seemed to be important risk factors for predicting FG severity and patient survival.

[Evaluation of HER2 protein overexpression in non-muscle-invasive bladder cancer with emphasis on tumour grade and recurrence]. / Evaluación de la sobreexpresión de proteína HER2 en cáncer vesical no músculo invasivo con énfasis en el grado tumoral y en la recurrencia.

OBJECTIVE: To evaluate the prognostic value of HER2 expression in non-muscle invasive bladder transitional cell carcinoma (TCC) with special emphasis in the high grade population. MATERIALS AND METHODS (PATIENTS): Tissue microarrays (TMA) were performed with representative TUR-B specimens from 84 patients with non-muscle invasive bladder TCC (40 pT1GII and 44 pT1GIII) treated in our institution. Depth of invasion and grade were uniformly assigned by the same pathologist who performed blind immunohistochemical analysis with Hercep test: 3+ was considered strong positive HER2 overexpression. Other clinico-pathological variables were also assessed. RESULTS: HER2 protein overexpression was detected in 30/44 (68.2%) pT1GIII lesions and predicted recurrence in this subgroup of bladder TCC (p<0.01). Negative HER2 expression was detected in 26/40 (65%) cases with pT1GII TCC, and this condition was more frequent in unifocal tumours, without angiogenesis, with low recurrence rate and without progression. Recurrence-free survival can also be anticipated by HER 2 expression within pT1GII tumours (p<0.01). CONCLUSION: HER2 expression using Hercep test may be useful to predict recurrence in non-muscle invasive bladder TCC. The potential application of this study, especially regarding prediction of response to BCG, should be prospectively confirmed in multi-institutional trials.

Synchronous Primary Tumors of the Kidney and Pancreas: Case Report

The simultaneous presence of primary carcinomas in the same patient is uncommon and synchronous primary tumors involving the kidney and pancreas are extremely rare. There are a few reports in the eng literature of synchronous primary malignancies of the kidney and pancreas. We present a 62-year-old man who had weight loss of 9 kg and epigastric pain. Findings showed a Furhman grade II renal papillary carcinoma confined to the kidney and a synchronous well differentiated pancreatic ductal adenocarcinoma
