Causes of chronic pain unrelated to surgical trauma after groin hernia repair: a prospective cohort study.

Background: Chronic inguinal pain (CIP) can be caused by musculoskeletal or neurological pathologies and by surgical trauma after inguinal hernia repair among other. The aim of this prospective cohort observational study was to find the incidence and causes of CIP unrelated to surgical trauma 12 months after inguinal hernia repair.

Methods: During sixteen months patients consulting a hernia center for groin-related symptoms were included in the study.

TEP With Long-Term Resorbable Mesh in Patients With Indirect Inguinal Hernia.

Background And Objectives: The role of long-term degradable implants in reducing the risk of chronic postoperative pain after inguinal hernia repair is still unclear. A pilot study using a synthetic long-term resorbable mesh in Lichtenstein repair showed good results regarding pain and discomfort in patients with indirect inguinal hernia (IH) without recurrences, but higher recurrence rate in patients with direct inguinal hernia (DH). The purpose of this study was to assess the incidence of pain and early recurrence in patients with LIH surgically treated with the TEP technique using a long-term degradable mesh.

The diffuse sound field in energetic analysis.

Measuring the degree of diffuseness of a sound field is crucial in many modern parametric spatial audio techniques. In these applications, intensity-based diffuseness estimators are particularly convenient, as the sound intensity can also be used to obtain, e.g.
