Coarctation of the aorta (CoA[1][2] or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word “coarctation” means narrowing. Coarctations are most common in the aortic arch. The arch may be small in babies with coarctations. Other heart defects may also occur when coarctation is present, typically occurring on the left side of the heart. When a patient has a coarctation, the left ventricle has to work harder. Since the aorta is narrowed, the left ventricle must generate a much higher pressure than normal in order to force enough blood through the aorta to deliver blood to the lower part of the body. If the narrowing is severe enough, the left ventricle may not be strong enough to push blood through the coarctation, thus resulting in lack of blood to the lower half of the body. Physiologically its complete form is manifested as interrupted aortic arch

Postmenopausal bleeding (PMB) is defined for practical purposes as vaginal bleeding occurring after twelve months of amenorrhoea, in a woman of the age where the menopause can be expected.[1] Hence it does not apply to a young woman, who has had amenorrhoea from anorexia nervosa, or a pregnancy followed by lactation. However, it can apply to younger women following premature ovarian failure or premature menopause. Unscheduled bleeding in women of menopausal age taking hormone replacement therapy (HRT) should be managed in the same way from a practical perspective.[2] 'Unscheduled bleeding' is defined as non-cyclical bleeding still continuing six months after commencing HRT or after six months of amenorrhoea.

Breast abscesses are often linked to mastitis – a condition that causes breast pain and swelling (inflammation), and usually affects women who are breastfeeding. Infections can occur during breastfeeding if bacteria enter your breast tissue, or if the milk ducts (tiny tubes) become blocked. This can cause mastitis which, if not treated, can result in an abscess forming. Women who aren't breastfeeding can also develop mastitis if bacteria enter the milk ducts through a sore or cracked nipple, or a nipple piercing. White blood cells are sent to attack the infection, which causes tissue at the site of the infection to die. This creates a small, hollow area that fills with pus (an abscess).

PURPOSE: Laparoscopic partial nephrectomy (LPN) is an alternative modality of treatment for small sized renal cell carcinoma. Robot assisted laparoscopic partial nephrectomy (RLPN) has also been performed with an advantage in repairing resected surface after tumor resection. We compare the periopera...

tive data of patients treated with laparoscopic partial nephrectomy with those of RLPN undertaken patients. MATERIAL AND METHOD: From September 2006 to April 2008, 22 patients were treated with LPN and 22 were RLPN. 3 arms were used for RLPN; camera was inserted through the 12mm, umbilical trocar port. The laparoscopic Bulldog clamp was used for the clamping of renal hilum. We retrospectively compared each group about tumor size, operation time, estimated blood loss, warm ischemic time and hospital stay. RESULT: Operation time of LPN was shorter than that of RLPN (p=0.033). Tumor size, estimated blood loss and hospital stay was not significant different in each group. No case had conversion to open surgery. 1 patient of RLPN group, however, had conversion to radical nephrectomy due to severe bleeding. CONCLUSION: RLPN was safe and feasible in small sized renal cell carcinoma. Warm ischemic time was reasonable and morbidity associated with RLPN was also low.

First described by Aubaniac in 1952, central venous catheterization, or central line placement, is a time-honored and tested technique of quickly accessing the major venous system. Benefits over peripheral access include greater longevity without infection, line security in situ, avoidance of phlebitis, larger lumens, multiple lumens for rapid administration of combinations of drugs, a route for nutritional support, fluid administration, and central venous pressure (CVP) monitoring. Central vein catheterization is also referred to as central line placement. Overall complication rates are as high as 15%, [1, 2, 3, 4] with mechanical complications reported in 5-19% of patients, [5, 6, 7] infectious complications in 5-26%, [1, 2, 4] and thrombotic complications in 2-26%. [1, 8] These complications are all potentially life-threatening and invariably consume significant resources to treat. Placement of a central vein catheter is a common procedure, and house staff require substantial training and supervision to become facile with this technique. A physician should have a thorough foreknowledge of the procedure and its complications before placing a central vein catheter. The supraclavicular approach was first put into clinical practice in 1965 and is an underused method for gaining central access. It offers several advantages over the infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-side approach offers a straighter path into the subclavian vein. In addition, this site is often more accessible during cardiopulmonary resuscitation (CPR) and during active surgical cases. Finally, in patients who are obese, this anatomic area is less distorted.
