Weight Loss Through Bariatric Surgery in Men Presents Beneficial Effects on Sexual Function, Symptoms of Testosterone Deficiency, and Hormonal Profile.

INTRODUCTION: Male obesity has a negative correlation with plasma testosterone (T) levels and sexual function (SF). AIM: To evaluate the effect of weight loss through bariatric surgery (BS) on SF, low T symptoms, and hormonal profiles in obese men. METHODS: Thirty-three men who underwent BS participated in this cohort study. Before surgery, all participants underwent clinical examinations, including anthropometric, lipid, glycemic, and hormonal evaluations. SF was evaluated using the International Index of Erectile Function (IIEF) questionnaire; low T symptoms were evaluated using the Aging Males' Symptoms (AMS) and Androgen Deficiency in the Aging Male (ADAM) questionnaires. The participants were reevaluated 6 months post-surgery. MAIN OUTCOME MEASURES: Sex hormone profile, SF, and low T symptoms RESULTS: After BS, a significant increase in mean total T (201 ± 111-548 ± 190 ng/dL, P < .001), free T (5.8 ± 2.8-9.3 ± 3.4 ng/dL, P < .001), bioavailable T (110.3 ± 57.8-198.6 ± 74.3 ng/dL, P < .001), and sexual hormone-binding globulin (19.8 ± 13.7-54.6 ± 23.2 nmol/L, P < .001) levels. There was a significant decrease in estradiol (64.6 ± 27.4-29.2 ± 20.0 [pg/mL], P < .001). SF significantly improved. The total IIEF score increased 5.2 points (62.3 ± 7.4-67.5 ± 7.4, P = .004), erectile function subdomain increased 2.4 points (25.7 ± 4.1-28.1 ± 3.9, P = .011), desire subdomain increased 1.0 points (8.3 ± 1.5-9.3 ± 1.6, P = .006), and intercourse satisfaction subdomain increased 1.2 points (11.4 ± 1.9-12.6 ± 1.8, P = .012). Post-surgery, a 44% reduction (P = .001) was observed in the positive ADAM questionnaire, and improvements in all domains of the AMS questionnaire were found (P < .001). CONCLUSION: Significant weight loss through BS improves erectile function, hormonal profile, and symptoms of T deficiency. Machado FP, Rhoden EL, Pioner SR, et al.

Hyperbaric oxygen therapy effects on tissue lesions in acute pancreatitis. Experimental study in rats.

OBJECTIVE: To study the effects of hyperbaric oxygen therapy on tissue lesions in an experimental model of acute pancreatitis induced by pancreatic duct ligation. ANIMALS: Forty-eight adult female Wistar rats were randomized into two groups (n=24): control group and hyperbaric oxygen therapy group. INTERVENTION: The second group was treated with a two-hour daily session of hyperbaric oxygen therapy at 2.5 ATA started 6 hours after pancreatic duct ligation. SETTING: The two groups were divided into 3 subgroups of 8 rats each undergoing euthanasia on days 1, 3, and 7 after the acute pancreatitis induction. MAIN OUTCOME MEASURES: The pancreas was evaluated according to the following histopathologic criteria: edema, hemorrhage, acinar necrosis and leukocyte infiltration. RESULTS: Hyperbaric oxygen therapy was efficient in significantly reducing acinar necrosis on the first day (P=0.049) and the foci of hemorrhage on the seventh day (P=0.050). The edema and leukocyte infiltration did not show the expected reduction. CONCLUSION: The utilization of a daily session of hyperbaric oxygen therapy at 2.5 ATA is efficient in reducing the hemorrhage and acinar necrosis but is not sufficient to reduce edema and leukocyte infiltration.

Tuberculose esofágica primária: relato de caso / Primary esophageal tuberculosis: case report

Esophageal tuberculosis is an extremely rare event, accounting for 0.2 percent of these cases affecting the esophagus. Most of them are secondary to pulmonary disease. The authors present a case of primary esophageal tuberculosis in a 40 years old HIV-positive female.
