The purpose of the technique was to develop a method of performing ultrasound-guided percutaneous biopsy of the augmented breast that would reduce risk of causing implant rupture. Using adhesive tape, we have displaced retropectoral implants away from the lesion to be biopsied. This resulted in greater space between the lesion and the implant and allowed ultrasound-guided biopsy to be accomplished with greater ease and with reduced risk of rupturing the implant.
An 83-year-old woman with history of hypertension treated chronically with verapamil 360 mg daily, presented with refractory hypokalemia and hypochloremic alkalosis. Initial physical examination demonstrated mild hypertension with proximal muscle weakness and normal cardiovascular exam.Initial workup revealed an a.m. cortisol level of 70 mcg/ dl (6-23), a 24-h urine-free cortisol of 5,719 lg (10-100), 1 mg overnight dexamethasone suppression test that showed a morning cortisol level of 54.6 lg/dl, and ACTH level of 123 pg/ml (6-58).
mesentery were recognized, as well as stenosis of the second part of the duodenum and the middle part of the colon ascendens. Frozen section analysis of the retroperitoneal lesion showed the presence of malignancy. The lesion was considered inoperable and palliative gastrojejunostomy and ileo-transverse anastomosis were performed. Microscopic analysis of the resected specimen showed the presence of metastatic ILC (Fig. 3), while immunohistochemical analysis for ER and PgR was positive for both receptors. The postoperative course of the patient was uneventful and she was discharged from the hospital on the 8th postoperative day in good condition.Double bubble sing is indicative of obstruction of the second part of duodenum. The left-sided bubble corresponds to the air-and fluid-filled stomach, while the bubble to the right of the midline refers to the proximal duodenum. DBS mainly presents in neonates with duodenal atresia, pyloric stenosis, annular pancreas, midgut volvulus, or Ladd bands. In adulthood, DBS most commonly presents in patients with disorders causing external compression of the duodenum, including choledochal cyst, mesenteric duplication cyst, and retroperitoneal tumors. Other disorders that present with DBS include acute pancreatitis, sigmoid volvulus, and small intestine obstruction. Infiltrating lobular carcinoma of the breast (ILC) is the second most common type of primary breast cancer accounting for 8-14% of all cases. Only few cases of metastatic ILC to retroperitoneum have been reported in the literature, as ILC mainly metastasizes to the bone marrow (21.2%), pleura and lungs (2.5%), gastrointestinal tract (mainly in stomach, small intestine, and rectum) (4.5%), and gynecological organs (4.5%). Physicians should be aware of these different metastatic patterns of lobular carcinoma of the breast to recognize early symptoms and signs of metastatic disease.
Der Einbau individueller Tyrosinreste, die an der C4‐Position des Phenolrings 13C‐markiert sind (Y11 und Y19 im Bild), bewirkt eine Verschiebung der resultierenden Tyrosinbande zu niedrigeren Wellenzahlen. Dies ermöglicht das simultane IR‐spektroskopische Verfolgen lokaler Konformationsänderungen in verschiedenen Bereichen eines Proteins, was für eine synthetische Variante der WW‐Domäne beispielhaft demonstriert wird.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
