Bartter syndrome is a rare inherited defect in the thick ascending limb of the loop of Henle. It is characterized by low potassium levels (hypokalemia), increased blood pH (alkalosis), and normal to low blood pressure. There are two types of Bartter syndrome: neonatal and classic
This video demonstrates the approach to a large base of tongue tumor, which was invading the ramus of the mandible. The procedure, named after Dr. Trotter, is really a median labiomandibuloglossotomy. In this case this poorly differentiated tumor was resected along with a portion of the floor of mouth. The entire area was reconstructed with a pectoralis major myocutaneous flap.
Patients are generally placed in a supine position with the head in an extended position. As noted above, Gardner-Wells tongs can be used for additional cervical traction. The hands can also be tied downward to increase the operative exposure. Once the surgical site is properly prepared with cleansing material, the appropriate surgical level is identified with intraoperative radiographs. A scalpel is used to make a linear longitudinal incision just medial to the body of the sternocleidomastoid muscle. The incision is made long enough to include at least 2 vertebral levels if a 1-level discectomy is being performed. Alternatively, transverse skin incisions over the targeted vertebral level can also be performed. The platysmal muscle is identified and incised. The platysmal incision can be extended if a multilevel decompression is the surgical aim. Extensive subplatysmal dissection is performed to reduce retraction injury.
St. Luke's originally broadcast this live in a webcast and later re-purposed it for air on KCRG-TV9 as an educational video. It is hosted by Ashley Hinson, KCRG-TV9 anchor and Dr. Sandeep Munjal. Dr. Jeff Nassif performs the knee replacement surgery on an eastern Iowa woman. St. Luke's has a rapid recovery joint replacement program, which gets people back to life quickly after surgery.
Hemorrhoids (HEM-uh-roids), also called piles, are swollen veins in your anus and lower rectum, similar to varicose veins. Hemorrhoids have a number of causes, although often the cause is unknown. They may result from straining during bowel movements or from the increased pressure on these veins during pregnancy.
Surgical site infections (SSIs) remain a prevalent threat to patient safety. Proper surgical hand scrub or rub techniques are essential to decreasing the incidence of SSIs. This video provides instructions on the anatomical surgical hand scrub procedure using the brushstroke method.

What are the disadvantages of male condoms? a moderately high failure rate when used improperly or inconsistently. the potential for diminished sensation. skin irritation, such as contact dermatitis, due to latex sensitivity or allergy. allergic reactions to spermicides, lubes, scents, and other chemicals in the condoms.
Skin Cysts Cysts are noncancerous, closed pockets of tissue that can be filled with fluid, pus, or other material. Cysts are common on the skin and can appear anywhere. They feel like large peas under the surface of the skin. Cysts can develop as a result of infection, clogging of sebaceous glands (oil glands), or around foreign bodies, such as earrings.
Debridement is the removal of necrotic tissue, foreign debris, bacterial growth, callus, wound edge, and wound bed tissue from chronic wounds in order to stimulate the wound healing process. Stimulation of wound healing mediated by debridement is thought to occur by the conversion of a chronic non-healing wound environment to an acute healing environment through the removal of cells that are not responsive to endogenous healing stimuli. Debridement is used commonly in standard wound treatment of diabetic foot ulcers (DFUs). Methods of debridement include surgery (sharp debridement), chemical debridement (antiseptics, polysaccharide beads, pastes), autolytic (hydrogels, hydrocolloids and transparent films), biosurgery (maggots), mechanical (hydrodebridement), and biochemical debridement (enzyme preparations). Callus is a buildup of keratinized skin formed under conditions of repeated pressure or friction and may contribute to ulcer formation by creating focal areas of high plantar pressure. The debridement of callus has been proposed to be relevant for both treatment and prevention of DFU. The purpose of this report is to retrieve and review existing evidence of comparative clinical effectiveness of different methods of debridement for the treatment of DFUs. Additionally examined in this report is the clinical effectiveness for treatment and prevention of DFU using callus debridement. Cost-effectiveness, and existing debridement guidelines for the treatment of DFUs will also be reviewed.
