1/196. A case of fibrosing mediastinitis with obstruction of superior vena cava and downhill esophageal varices: a rare cause of upper gastrointestinal hemorrhage.Fibrosing mediastinitis (FM) is an excessive fibrotic reaction that occurs in the mediastinum and may lead to compression of mediastinal structures (especially vascular or bronchial). In the present study we describe the first case report of FM, in a patient who developed downhill esophageal varices and bleeding, which was secondary to superior vena cava obstruction.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
2/196. Sclerosing mesenteritis seen clinically as pancreatic pseudotumor: two cases and a review.Sclerosing mesenteritis is an uncommon nonneoplastic inflammatory process in the mesentery that is seen as a pseudotumor, usually involving the small bowel mesentery, the mesenteric fat, and less commonly, the mesentery of the large bowel. We report two cases of sclerosing mesenteritis and review the literature on this rare disease. Both patients had pain, profound weight loss, and a mass on computed tomography (CT) scan of the abdomen. The provisional diagnosis was pancreatic neoplasm on the basis of clinical presentation and imaging studies. The diagnosis of sclerosing mesenteritis was established by histologic findings in biopsy material obtained at laparotomy in both cases. Interval histologic studies in one patient who had a high CA 19-9 level, progressive biliary ductal and partial duodenal compression, revealed a transitional histologic pattern from predominant inflammation and fat necrosis to predominant fibrosis. This may explain the varied descriptive terms used in the literature to describe this entity.- - - - - - - - - - ranking = 0.025901563582968keywords = duct (Clic here for more details about this article) |
3/196. Novel surgical treatment and gastric pathology in diabetic gastroparesis.AIMS: Observations are made on four Type 1 diabetic patients with the rare syndrome of intractable vomiting from confirmed gastroparesis, to determine whether radical surgery would alleviate their symptoms and subsequently to examine in detail the gastric histopathology. methods: The surgical approach consisted of an approximate 70% resection of the stomach, including the antrum and pylorus, with closure of the duodenum and restoration of gastrointestinal continuity with a 60-cm Roux-en-Y jejunal loop. Four longstanding Type 1 diabetic patients were examined and treated as described. They were all women in the age range 2741 years with grossly abnormal autonomic function tests in whom other causes for gastric paresis had been excluded. RESULTS: vomiting episodes leading to multiple hospital admissions (6-8) in the year preceding surgery were eliminated in three of the four patients, while in the fourth initial success was followed by the need for dialysis for renal failure. Gastric histopathology showed evidence of smooth muscle degeneration and fibrosis, with eosinophilic inclusion bodies (M-bodies) which appear to be unique to this condition. The findings suggest the presence of a gastromyopathy. CONCLUSIONS: Satisfactory relief of intractable vomiting from diabetic gastroparesis was achieved by a novel radical surgical procedure. Histopathological findings suggest that gastromyopathy may contribute to the production of this syndrome.- - - - - - - - - - ranking = 0.025901563582968keywords = duct (Clic here for more details about this article) |
4/196. Low-intensity laser therapy for benign fibrotic lumps in the breast following reduction mammaplasty.BACKGROUND AND PURPOSE: Fibrotic masses in the breast secondary to fat necrosis or hematoma are a complication of breast reduction mammaplasty. The treatment commonly recommended for this condition is early surgical debridement of necrotic tissue from the entire area, which causes scarring. This case report describes the use of low-intensity laser therapy for fibrotic lumps following reduction mammaplasty. CASE DESCRIPTION: The patient was a 46-year-old woman who had breast reduction surgery 80 days prior to referral for physical therapy. At the time of referral, the largest mass was 8.0 cm in diameter. The patient reported pain and said she was distressed about the breast disfigurement. Laser irradiation was initiated at an energy density (ED) of 20 J/cm2 and a pulse repetition rate of 5,000 pulses per second. The laser settings were adjusted during the 8-month treatment period. The final ED was 50 J/cm2. OUTCOMES: The mass was 33% of its original size after 3 treatments over the initial 11-day period. pain relief was immediate. The rate of resolution decreased after the initial period. The patient had some tissue thickening at the time of discharge after 6 months of treatment. DISCUSSION: This case demonstrates the potential use of laser therapy as a treatment for benign breast lumps following mammaplasty.- - - - - - - - - - ranking = 0.18131094508078keywords = duct (Clic here for more details about this article) |
5/196. Chronic pancreatitis and inflammatory bowel disease: true or coincidental association?OBJECTIVE: Several cases of pancreatitis have been described during the course of Crohn's disease (CD) or ulcerative colitis (UC), but many of them were related to either biliary lithiasis or drug intake. We tried to evaluate the clinical and morphological features of so-called idiopathic pancreatitis associated with inflammatory bowel disease and to define their pathological characteristics. methods: Chronic idiopathic pancreatitis was diagnosed on the basis of abnormal pancreatograms suggestive of chronic pancreatitis associated with or without impaired exocrine pancreatic function, or pathological examination in patients undergoing pancreatic resection. We found 6 patients presenting with features of chronic idiopathic pancreatitis and UC and 2 patients with CD seen between 1981 and 1996 in three hospital centers of the south of france. A review of the literature has identified 6 cases of pancreatitis associated with UC and 14 cases of pancreatitis associated with CD based on the above criteria. RESULTS: hyperamylasemia was not a sensitive test since it was present in 44% and 64% of patients with UC or CD. In UC, pancreatitis was a prior manifestation in 58% of patients. In contrast, the pancreatitis appeared after the onset of CD in 56% of the cases. In patients with UC, pancreatitis were associated with severe disease revealed by pancolitis (42%) and subsequent surgery. Bile duct involvement was more frequent in patients with UC than with CD (58% vs 12%) mostly in the absence of sclerosing cholangitis (16% vs 6%). weight loss and pancreatic duct stenosis were also more frequent in UC than in CD (41% vs 12% and 50% vs 23%, respectively). Pathological specimens were analyzed in 5 patients and demonstrated the presence of inter- and intralobular fibrosis with marked acinar regression in 3 and the presence of granulomas in 2 patients, both with CD. CONCLUSIONS: pancreatitis is a rare extraintestinal manifestation of inflammatory bowel disease. Chronic pancreatitis associated with UC differs from that observed in CD by the presence of more frequent bile duct involvement, weight loss, and pancreatic duct stenosis, possibly giving a pseudotumor pattern.- - - - - - - - - - ranking = 0.31722339988295keywords = bile duct, duct, bile (Clic here for more details about this article) |
6/196. nasolacrimal duct obstruction and orbital cellulitis associated with chronic intranasal cocaine abuse.OBJECTIVE: To report the association of acquired nasolacrimal duct obstruction and orbital cellulitis in patients with a history of chronic intranasal cocaine abuse. methods: Retrospective, consecutive case series. Results of imaging, histopathologic examinations, and clinical courses of these patients were studied. RESULTS: Five women and 2 men (mean age, 41 years) with a history of chronic intranasal cocaine abuse (mean, 11 years; range, 5-20 years) presented with epiphora and in some cases acute onset of periorbital pain, edema, and erythema associated with fever. The suspicion of intranasal cocaine abuse was made on anterior rhinoscopy with the detection of an absent nasal septum and inferior turbinate. Computed tomographic and magnetic resonance imaging findings in 4 patients included extensive bony destruction of the normal orbital wall architecture, opacification of the sinuses, and the presence of an intraorbital tissue mass. Histopathologic examination of the nasolacrimal duct in 2 patients and of the orbital mass in a third patient revealed marked chronic inflammation with fibrosis causing secondary nasolacrimal duct obstruction. Six patients were treated with systemic antibiotics followed by dacryocystorhinostomy in 3 patients, and a pericranial flap to insulate the exposed orbit in 1 patient. CONCLUSIONS: Chronic intranasal cocaine abuse can result in extensive bony destruction of the orbital walls with associated orbital cellulitis, and should be included in the differential diagnosis of acquired nasolacrimal duct obstruction. Anterior rhinoscopy is very helpful in establishing the correct diagnosis in these patients.- - - - - - - - - - ranking = 1.6072125086637keywords = obstruction, duct (Clic here for more details about this article) |
7/196. Orbital blowout fracture with persistent mobility deficit due to fibrosis of the inferior rectus muscle and perimuscular tissue.A case of orbital blowout fracture accompanied by fibrosis of the inferior rectus muscle resulting in an irreversible orbital mobility deficit is reported. An 8-year-old girl with an orbital blowout fracture was treated with steroids for 10 days, as with other cases in our department. She exhibited a disturbance of vertical eye movement and a positive forced duction test result. Although surgery was performed on day 13, and on day 27 due to poor recovery after the first operation, almost no improvement of the ocular movement was noted. The results of a traction test, performed during the second operation, suggested that the inferior rectus muscle had adhered to the periosteum. magnetic resonance imaging performed 3 days after the second operation revealed fibrosis of the inferior rectus muscle and perimuscular tissue, resulting in an irreversible disturbance of the vertical ocular movement. The present findings suggest that the need for and timing of surgery in patients with blowout fractures should be determined on an individual basis.- - - - - - - - - - ranking = 0.025901563582968keywords = duct (Clic here for more details about this article) |
8/196. Fibrosing colonopathy in an adult owing to over use of pancreatic enzyme supplements.A woman, then in her late 20s, underwent a cholecystectomy in 1962 for gallstone disease and subsequent common bile duct stones were managed endoscopically. However, because of unrelenting pain, a pylorus preserving pancreaticoduodenectomy was done in 1990 and in the following years the patient took large amounts of pancreatic enzyme supplements. She developed large bowel obstruction in 1997 and a right hemicolectomy was undertaken. histology confirmed fibrosing colonopathy of the ascending colon and caecum. Her pancreatic enzyme dose was reduced and her subsequent course has been uncomplicated.- - - - - - - - - - ranking = 0.43951870913404keywords = obstruction, bile duct, duct, bile (Clic here for more details about this article) |
9/196. Percutaneous stenting of right pulmonary artery stenosis in fibrosing mediastinitis.pulmonary artery stenosis is an uncommon complication of fibrosing mediastinitis. Previous medical and surgical therapies have provided limited clinical efficacy without objective evidence of clinical improvement. With the advantages of limited invasiveness and absent need for prolonged drug therapy, percutaneous stent deployment to relieve pulmonary artery obstruction represents a novel treatment for this rare disorder.- - - - - - - - - - ranking = 0.2keywords = obstruction (Clic here for more details about this article) |
10/196. Fibrosing cholestatic hepatitis: a report of three cases.Fibrosing cholestatic hepatitis is an aggressive and usually fatal form of viral hepatitis in immunosuppressed patients. We report three cases of fibrosing cholestatic hepatitis in various clinical situations. Case 1 was a 50-year-old man who underwent a liver transplant for hepatitis b virus (HBV)-associated liver cirrhosis. Two and a half years after the transplant, he complained of fever and jaundice, and liver enzymes were slightly elevated. serum HBsAg was positive. Case 2 was a 30-year-old man in an immunosuppressed state after chemotherapy for acute lymphoblastic leukemia. He was a HBV carrier. Liver enzymes and total bilirubin were markedly elevated. Case 3 was a 50-year-old man who underwent renal transplantation as a known HBV carrier. One year after the transplant, jaundice developed abruptly, but liver enzymes were not significantly elevated. Microscopically lobules were markedly disarrayed, showing ballooning degeneration of hepatocytes, prominent pericellular fibrosis, and marked canalicular or intracytoplasmic cholestasis. Portal inflammation was mild, but interphase activity was definite and cholangiolar proliferation was prominent. hepatocytes were diffusely positive for HBsAg and HBcAg in various patterns. patients died of liver failure within 1 to 3 months after liver biopsy in spite of anti-viral treatment.- - - - - - - - - - ranking = 0.81605863191662keywords = cholestasis (Clic here for more details about this article) |
