Article Abstract
A 53-year-old man with chronic kidney failure was referred to perform an 18 F-FDOPA PET/CT to characterize a mass located on the right spermatic cord. Previously, the pathological analysis of CT-guided biopsies suggested paraganglioma or metastatic lesion of pheochromocytoma. Serum normetanephrine and serum metanephrine values were respectively 2- and 1.5-fold greater than the normal upper limit, which could be explained by the chronic kidney failure. PET/CT images revealed intense 18 F-FDOPA uptake of the mass without any other pathological findings, suggesting the diagnosis of paraganglioma. Pathological examination of surgical specimen confirmed the diagnosis of paraganglioma of the spermatic cord, which is exceptional.

Purpose Of Review: Inguinal hernia repair remains one of the most common pediatric surgical procedures. Advances in minimally invasive techniques have made laparoscopic herniorrhaphy a safe alternative to open surgery. This review summarizes clinical outcomes in open and laparoscopic pediatric inguinal hernia repair, discusses technical considerations including anesthetic choice, and reviews patient and surgical factors relevant to surgical approach and timing.

A 19-year-old Oldenburg stallion was presented multiple times over the course of several months with recurrent colic signs. At each examination, an enlargement of the scrotum was noted, which could not be further specified by palpation and ultrasonographic examination. The increase in circumference was noted both on palpation and on inspection and the size remained unchanged throughout.

Currently, infertility is one of the major problems affecting up to 12% of couples worldwide, with more than a quarter of cases being male-related. It is assumed that Leukocyte-poor platelet-rich plasma (LP-PRP) can improve the function of germ cells and serve as a regenerative substrate as a source of biologically active substances that play an important role in the process of spermatogenesis in infertile men. We aimed to evaluate the proliferation, apoptosis, and growth factors of germ cells after the administration of LP-PRP in patients with non-obstructive azoospermia.

The aim of this study was to compare postoperative complications and long-term clinical efficacy of electrospun composite biomaterial and porcine small intestine submucosa (SIS) patch in open inguinal herniorrhaphy. A prospective, randomized, single-blind, controlled, multicenter study was used to select 172 patients with inguinal hernia who met the inclusion criteria in 3 hospitals. All participants were randomly assigned (1:1) and treated by open inguinal herniorrhaphy.
