Obturator hernia is a rare but clinically relevant cause of intestinal obstruction, usually found in elderly, thin, multiparous women. It is difficult to diagnose, leading to diagnostic delay with a high incidence of strangulation and a high mortality rate. Surgery is the only reported treatment. We report the case of an 86-year-old woman, in whom an early diagnosis of incarcerated obturator hernia was made with subsequent reduction by compression with an ultrasound transducer. When the risk of strangulation is presumed to be low, ultrasound-guided reduction of an obturator hernia is achievable and worth considering...

BACKGROUND: Laxity of soft tissues after total hip arthroplasty is considered to be a cause of accelerated wear of bearing surfaces and dislocation. The purpose of this study is to assess the contribution of the anterior and posterior capsular ligamentous complexes and the short external rotators, except the quadratus femoris, on the stability of the hip against axial traction. METHODS: The study subjects comprised 7 fresh cadavers with 12 normal hip joints. In 6 hips, soft tissues surrounding the hip joint were resected in the following order to simulate the anterior approach: anterior capsule, posterior capsule, piriformis, conjoined tendon, and external obturator...

Loss of part of the face is associated with physical disability, social isolation and immense psychological trauma. Proper rehabilitation of such a patient is a challenging yet satisfying task for a maxillofacial prosthodontist. Facial prostheses are commonly fabricated of silicone because of many favorable properties, though it predisposes to fungal growth.This report is of a patient with history of uncontrolled diabetes and associated invasive fungal infection, leading to a complex oro-facial defect, which was rehabilitated successfully with a silicone facial prosthesis lined by a material more resistant to fungal growth along with a cast partial obturator...

Background: Herbs have renewed importance in this modern era for their antimicrobial properties and fewer side effects. So a novel idea to use these herbs for pulpectomy; was implemented. There are chances of failure of pulpectomy due to inefficient removal of microbial load. Thus, for a successful endodontic treatment, obturating material with optimum antimicrobial properties is advocated in the present study. Aim: To compare and evaluate the antibacterial efficacy of zinc oxide eugenol, zinc oxide with tulsi extract and zinc oxide with aloe vera as obturating materials against E...

Gin-Ho Lo
Acute esophageal variceal hemorrhage is a dreaded complication of portal hypertension. Its management has evolved rapidly in recent years. Endoscopic therapy is often employed to arrest bleeding varices as well as to prevent early rebleeding. The combination of vasoconstrictor and endoscopic therapy is superior to vasoconstrictor or endoscopic therapy alone for control of acute esophageal variceal hemorrhage. After control of acute variceal bleeding, combination of banding ligation and beta-blockers is generally recommended to prevent variceal rebleeding...
