The effects on bacterial translocation and tissue damage of selenium treatment in an experimental intestina ischaemia-reperfusion model.

Background: The free oxygen radicals formed with reperfusion following intestinal ischaemia are extremely toxic for the cells. Glutathione peroxidase, an important enzyme that prevents the formation of reactive oxygen species, requires selenium as a co-factor. This study aims to demonstrate the effects of selenium administration on reducing ischaemia-reperfusion damage.

Comparison of the Effects of Plateletrich Plasma Prepared in Various Forms on the Healing of Dermal Wounds in Rats.

Objective: This study was designed to evaluate the effects of 3 different forms of platelet-rich plasma (PRP) on the healing process, wound healing rate, and histopathological changes that occur during recovery of open dermal wounds.

Materials And Methods: A 2 cm x 1 cm full-thickness skin defect was made on the backs of 40 Wistar female rats that were divided into 4 groups of 10. In group 1 (control group), the wounds were cleaned with saline; in group 2, the wounds were covered with PRP gel obtained by single centrifugation; in group 3, the wounds were covered with liquid PRP obtained by double centrifugation; and in group 4, PRP gel obtained by double centrifugation with added thrombin was applied on the dermal wounds.

Does the presence of a mesh have an effect on the testicular blood flow after surgical repair of indirect inguinal hernia?

Purpose: Modern treatment of inguinal hernias includes prosthetic mesh repairs. However, direct contact of the mesh to the vessels in the inguinal canal and perimesh fibrosis may have a negative impact on testicular flow. The aim of this prospective study was to evaluate the effect of mesh implantation/perimesh fibrosis on testicular flow after repair of indirect inguinal hernias (IIHs).

Acute appendicitis presenting with abdominal wall and right groin abscess: a case report.

We report a case of right lower abdominal wall and groin abscess resulting from acute appendicitis. The patient was an 27-year-old man who had no apparent abdominal signs and was brought to the hospital due to progressive painful swelling of right lower abdomen and the groin for 10 d. Significant inflammatory changes of soft tissue involving the right lower trunk were noted without any apparent signs of peritonitis.

Primary anorectal malignant melanoma: two case reports and review of the literature.

Anorectal melanoma is a very rare tumor with poor prognosis because of delay in diagnosis. It is often mistaken for benign conditions such as hemorrhoids or rectal polyps. Surgical treatment ranges from local excision to radical abdominoperinal resection.
