- Impact of body mass index, age and varicocele on reproductive hormone profile from elderly men(2016) YAMACAKE, K. G. R.; COCUZZA, M.; TORRICELLI, F. C. M.; TISEO, B. C.; FRATI, R.; FREIRE, G. C.; ANTUNES, A. A.; SROUGI, M.Objectives: To study the impact of obesity, age and varicocele on sexual hormones fof adult and elderly men. Materials and Methods: 875 men who were screened for prostate cancer were enrolled in this study. Data recorded comprised age, body mass index (BMI), serum levels of total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH) and follicular stimulating hormone (FSH). Patients were divided in groups according to their BMI in underweight, normal weight, overweight and obese grades 1, 2 or 3. First, it was studied the association between age, BMI, and hormone profile. Then, clinical varicocele was evaluated in 298 patients to assess its correlation to the others parameters. Results: Obese patients had lower levels of TT, FT and SHBG (p<0.001) compared to underweight or normal weight patients. There were no differences in age (p=0.113), FSH serum levels (p=0.863) and LH serum levels (p=0.218) between obese and non-obese patients. Obese grade 3 had lower levels of TT and FT compared to obese grade 1 and 2 (p<0.05). There was no difference in the SHBG levels (p=0.120) among obese patients. There was no association between varicocele and BMI; and varicocele did not impact on testosterone or SHBG levels. Conclusions: Men with higher BMI have a lower serum level of TT, FT and SHBG. The presence of clinical varicocele as well as its grade has no impact on hormone profile in elderly men.
- Infrared Thermometer: an accurate tool for temperature measurement during renal surgery(2013) MARCHINI, Giovanni Scala; DUARTE, Ricardo Jordao; MITRE, Anuar Ibrahim; TISEO, Bruno Camargo; CASSAO, Valter Dell'Acqua; TORRICELLI, Fabio Cesar Miranda; ARAP, Marco Antonio; SROUGI, MiguelPurpose: To evaluate infrared thermometer (IRT) accuracy compared to standard digital thermometer in measuring kidney temperature during arterial clamping with and without renal cooling. Materials and Methods: 20 pigs weighting 20Kg underwent selective right renal arterial clamping, 10 with (Group 1 - Cold Ischemia with ice slush) and 10 without renal cooling (Group 2 - Warm Ischemia). Arterial clamping was performed without venous clamping. Renal temperature was serially measured following clamping of the main renal artery with the IRT and a digital contact thermometer (DT): immediate after clamping (T0), after 2 (T2), 5 (T5) and 10 minutes (T10). Temperature values were expressed in mean, standard deviation and range for each thermometer. We used the T student test to compare means and considered p < 0.05 to be statistically significant. Results: In Group 1, mean DT surface temperature decrease was 12.6 +/- 4.1 degrees C (5-19 degrees C) while deep DT temperature decrease was 15.8 +/- 1.5 degrees C (15- 18 degrees C). For the IRT, mean temperature decrease was 9.1 +/- 3.8 degrees C (3-14 degrees C). There was no statistically significant difference between thermometers. In Group 2, surface temperature decrease for DT was 2.7 +/- 1.8 \degrees C (0-4 degrees C) and mean deep temperature decrease was 0.5 +/- 1.0 degrees C (0-3 degrees C). For IRT, mean temperature decrease was 3.1 +/- 1.9 degrees C (0-6 degrees C). No statistically significant difference between thermometers was found at any time point. Conclusions: IRT proved to be an accurate non-invasive precise device for renal temperature monitoring during kidney surgery. External ice slush cooling confirmed to be fast and effective at cooling the pig model.
- Development and Initial Validation of a Scoring System to Diagnose Testicular Torsion in Children(2013) BARBOSA, Joao A.; TISEO, Bruno Camargo; BARAYAN, Ghassan A.; ROSMAN, Brian M.; TORRICELLI, Fabio Cesar Miranda; PASSEROTTI, Carlo C.; SROUGI, Miguel; RETIK, Alan B.; NGUYEN, Hiep T.Purpose: Testicular torsion is a surgical emergency requiring prompt intervention. Although clinical diagnosis is recommended, scrotal ultrasound is frequently ordered, delaying treatment. We created a scoring system to diagnose testicular torsion, decreasing the indication for ultrasound. Materials and Methods: We prospectively evaluated 338 patients with acute scrotum, of whom 51 had testicular torsion. Physical examination was performed by a urologist, and all patients underwent scrotal ultrasound. Univariate analysis and logistic regression were performed, and a scoring system for risk stratification of torsion was created. Retrospective validation was performed with 2 independent data sets. Results: The scoring system consisted of testicular swelling (2 points), hard testicle (2), absent cremasteric reflex (1), nausea/vomiting (1) and high riding testis (1). Cutoffs for low and high risk were 2 and 5 points, respectively. Ultrasound would be indicated only for the intermediate risk group. In the prospective data set 69% of patients had low, 19% intermediate and 11.5% high risk. Negative and positive predictive values were 100% for cutoffs of 2 and 5, respectively (specificity 81%, sensitivity 76%). Retrospective validation in 1 data set showed 66% of patients at low, 16% intermediate and 17% high risk. Negative and positive predictive values for cutoffs of 2 and 5 were 100% (specificity 97%, sensitivity 54%). The second retrospective data set included only torsion cases, none of which was misdiagnosed by the scoring system. Conclusions: This scoring system can potentially diagnose or rule out testicular torsion in 80% of cases, with high positive and negative predictive values for selected cutoffs. Ultrasound orders would be decreased to 20% of acute scrotum cases. Prospective validation of this scoring system is necessary.
