Dementia is the name for a group of symptoms that commonly include problems with memory, thinking, problem solving, language and perception. In a person with dementia, these symptoms are bad enough to affect daily life.

Perineal repair after episiotomy or spontaneous obstetric laceration is one of the most common surgical procedures. Potential sequelae of obstetric perineal lacerations include chronic perineal pain,1 dyspareunia,2 and urinary and fecal incontinence.3–5 Few studies of laceration repair techniques exist to support the development of an evidence-based approach to perineal repair. This article discusses a repair method that emphasizes anatomic detail, with the expectation that an anatomically correct perineal repair may result in a better long-term functional outcome.

Needle fasciotomy (aponeurotomy) is usually a 15-Minute in-office procedure for Dupuytren's contracture. Performed under local anesthesia, in the office, by board-certified plastic surgeon Reza Momeni, MD. This is a minimally invasive treatment for Dupuytren's.

Scleroderma (skleer-oh-DUR-muh) is a group of rare diseases that involve the hardening and tightening of the skin and connective tissues — the fibers that provide the framework and support for your body. In some people, scleroderma affects only the skin. But in many people, scleroderma also harms structures beyond the skin — such as blood vessels, internal organs and the digestive tract. Signs and symptoms vary, depending on which structures are affected. Scleroderma affects women more often than men and most commonly occurs between the ages of 30 and 50. While there is no cure for scleroderma, a variety of treatments can ease symptoms and improve quality of life.

Austin Vampire Facelift provider Dr. David Sneed gives us a comprehensive overview of this new facial rejuvenation technology also known as PRP. This nonsurgical anti-aging treatment utilizes the patient's own blood to stimulate the growth of new collagen, tighten skin and smooth out wrinkles.

Cytomegalovirus (CMV) continues to have a tremendous impact in solid organ transplantation despite remarkable advances in its diagnosis, prevention and treatment. It can affect allograft function and increase patient morbidity and mortality through a number of direct and indirect effects. Patients may develop asymptomatic viremia, CMV syndrome or tissue-invasive disease. Late-onset CMV disease continues to be a major problem in high-risk patients after completion of antiviral prophylaxis. Emerging data suggests that immunologic monitoring may be useful in predicting the risk of late onset CMV disease. There is now increasing interest in the development of an effective vaccine for prevention. Novel antiviral drugs with unique mechanisms of action and lesser toxicity are being developed. Viral load quantification is now undergoing standardization, and this will permit the generation of clinically relevant viral thresholds for the management of patients. This article provides a brief overview of the contemporary epidemiology, clinical presentation, diagnosis, prevention and treatment of CMV infection in solid organ transplant recipients.

Nerve damage can start as numbness or tingling and progress to an intense feeling of burning or stabbing. What to know about treatment options:

Amniocentesis,before the actual procedure, a local anesthetic is sometimes given to relieve the pain when inserting the needle used to withdraw the fluid. A needle is usually inserted through the mother's abdominal wall or at the end of the vagina, and through the wall of the uterus into the amniotic sac. With assistance from ultrasound, a physician aims towards an area of the sac that is away from the fetus and extracts a small amount of amniotic fluid for testing. The puncture heals, and the amniotic sac replenishes the liquid over a day or so. After the amniotic fluid is extracted, the fetal cells are separated from it using a centrifuge, and the fetal chromosomes are examined for abnormalities. Various genetic testing may be performed, but the three most common abnormalities tested for are Down's syndrome, Trisomy 18 and spina bifida. Amniocentesis can be performed as soon as sufficient amniotic fluid surrounds the fetus to allow a sample to be recovered relatively safely, usually no earlier than the 14th week of pregnancy. Often, genetic counseling is offered in conjunction with amniocentesis.

Bartter syndrome has traditionally been classified into three main clinical variants, as follows: Neonatal (or antenatal) Bartter syndrome Classic Bartter syndrome Gitelman syndrome Advances in molecular diagnostics have revealed that Bartter syndrome results from mutations in numerous genes that affect the function of ion channels and transporters that normally mediate transepithelial salt reabsorption in the distal nephron segments. Hundreds of mutations have been identified to date. Such advances may result in the development of new therapies (see the image below). [2] (See Pathophysiology and Etiology.)

Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
