Megacolon, as well as megarectum, is a descriptive term. It denotes dilatation of the colon that is not caused by mechanical obstruction.[1, 2] Although the definition of megacolon has varied in the literature, most researchers use the measurement of greater than 12 cm for the cecum as the standard. Because the diameter of the large intestine varies, the following definitions would also be considered: greater than 6.5 cm in the rectosigmoid region and greater than 8 cm for the ascending colon. Megacolon can be divided into the following 3 categories: Acute megacolon ( pseudo-obstruction) Chronic megacolon, which includes congenital, acquired, and idiopathic causes Toxic megacolon

Vatche, Minassian, MD, MPH, Chief of Urogynecology, and Sarah Cohen, MD, MPH, Director of the Minimally Invasive Gynecologic Surgery Fellowship Program at Brigham and Women’s Hospital, perform a laparoscopic burch colposuspension, a procedure used to correct stress urinary incontinence.

Stress urinary incontinence is one of the most common types of incontinence and is characterized by urinary leakage during physical activities including coughing, sneezing, exercising, lifting, and laughing. As the condition progresses, it can become severe enough to happen with simple acts such as bending and walking. This condition is due to an anatomic weakness of the bladder neck which typically maintains the seal of urine during activity. Stress incontinence can result from a variety of conditions including vaginal childbirth, aging, menopause and obesity. As this is an anatomic condition, primary treatment may involve pelvic floor exercises and/or minimally invasive surgery.

Immunohistochemistry or IHC refers to the process of detecting antigens (e.g., proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues.[1] IHC takes its name from the roots "immuno," in reference to antibodies used in the procedure, and "histo," meaning tissue (compare to immunocytochemistry). Immunohistochemical staining is widely used in the diagnosis of abnormal cells such as those found in cancerous tumors. Specific molecular markers are characteristic of particular cellular events such as proliferation or cell death (apoptosis). IHC is also widely used in basic research to understand the distribution and localization of biomarkers and differentially expressed proteins in different parts of a biological tissue. Visualising an antibody-antigen interaction can be accomplished in a number of ways. In the most common instance, an antibody is conjugated to an enzyme, such as peroxidase, that can catalyse a colour-producing reaction. Alternatively, the antibody can also be tagged to a fluorophore, such as fluorescein or rhodamine
