RESUMO

A 77-year-old man presented to the Department of Internal Medicine with a chief complaint of abdominal pain. During the outpatient examination, a computed tomography (CT) scan showed gallstones. The patient developed worsening abdominal pain and fever and was admitted to the emergency department. He was diagnosed with cholecystitis and hospitalized. Treatment with antimicrobial agents was initiated. On the second day of hospitalization, the patient developed a fever of 39°C, hypotension, and oliguria. An emergency CT scan was performed, which showed gas production in the gallbladder. He was diagnosed with emphysematous cholecystitis, and emergency percutaneous transhepatic gallbladder drainage was performed. The patient was transferred to the high-care unit, and intensive care was initiated. On the eighth day, a follow-up CT scan showed an abscess in the gallbladder bed, and drainage was performed percutaneously. His general condition gradually improved, and he was discharged from the hospital on day 24. The patient was readmitted for cholecystectomy three months after the initial admission. The prognosis of sepsis caused by Clostridium perfringens is extremely poor, with a mortality rate of 70%-100%. We present a case of emphysematous cholecystitis successfully treated with multimodal treatment despite the presence of sepsis due to Clostridium perfringens and discuss the possible prognostic factors by reviewing the literature.

RESUMO

BACKGROUND: Although non-mass lesions on breast ultrasonography have become relatively common, they remain very difficult to diagnose. The purpose of this study was to evaluate the usefulness of contrast enhanced magnetic resonance imaging (MRI) in managing non-mass lesions. METHODS: A total of 82 cases of non-mass lesions visible on breast ultrasonography who were subjected to contrast enhanced MRI (CE-MRI) were available for assessment. These lesions were evaluated in terms of the association between the enhancement pattern on contrast enhanced MRI and the pathological or cytological diagnosis. RESULTS: Thirty-three of 82 (40.2%) non-mass image-forming lesions were seen as enhanced lesions on CE-MRI, of which 32 revealed non-masslike enhancements. Of the 19 breast cancers detected as non-mass image-forming lesions, 18 (94.7%) had an enhancement pattern not suggestive of a mass, so breast cancers comprised 56.3 % (18/32) of the lesions. Most of the breast cancers tended to emerge in a setting of duct dilatation with internal echoes (45.5%; 5/11) or low echo areas with indistinct margins (32.4%; 11/34). Morphologically, segmental (57.9%; 11/19) and regional (21.1%; 4/19) enhancements were common patterns of breast cancer which showed up as non-mass image-forming lesions. On the other hand, 49 of 82 (59.8%) non-mass image-forming lesions were not enhanced and 28 of 49 cases underwent pathological examination. Only one case was breast cancer with category 5 microcalcifications and although about half of the remaining 21 cases were followed for at least 12 months, no breast cancers were found. CONCLUSION: Contrast enhanced MRI was useful for detecting breast cancer in cases of non-mass image-forming lesions. On the other hand, except for cases in which mammography was suspicious for malignancy, lesions showing no enhanced areas may be safely followed, because the possibility of breast cancer is minute.

RESUMO

A 49-year-old, previously healthy woman sought treatment for abdominal pain. Colonoscopy revealed ascending colon cancer. Computed tomography and angiography showed splenic metastasis and thrombosis extending from the splenic vein to the portal vein. She underwent right hemicolectomy, splenectomy, and distal pancreatomy. Histological findings showed no malignant cell in the splenic vein which was filled with organizing thrombus. We postulate the mechanism of splenic vein thrombosis in our case to be secondary to the extrinsic compression of the splenic vein by the splenic metastasis or by the inflammatory process produced by the splenic metastasis. In conclusion, we suggest that splenic metastasis should be added to the list of differential diagnosis which causes splenic vein thrombosis. In the absence of other sites of neoplastic disease, splenectomy seems to be the preferred therapy because it can be performed with low morbidity and harbors the potential for long-term survival.

RESUMO

Diabetic mastopathy is an uncommon tumor-like proliferation of fibrous tissue of the breast that usually occurs in a patient who has suffered from type I diabetes mellitus of long duration. Here we report a rare case of diabetic mastopathy that occurred in type II non-insulin dependent diabetes mellitus. This patient was a 63-year-old postmenopausal woman. Mammography, ultrasonography and MR imaging could not distinguish it from breast cancer. Although the core needle biopsy specimen showed fibrosis without evidence of malignancy, excisional biopsy was performed. Histological findings demonstrated typical diabetic mastopathy with keloid-like fibrosis, perivascular lymphocytic infiltration, and lymphocytic lobulitis without evidence of malignancy. These lymphocytes were composed predominantly of B-cells. Five months after surgical biopsy, a nodular formation approximately 4 cm in diameter recurred adjacent to the resected end of the biopsy.

RESUMO

We report a case of 28-year-old woman presenting with small bowel obstruction. She had neither prior surgery nor delivery. An upright abdominal radiograph revealed several air-fluid levels in the small bowel in the midabdomen and the pelvic cavity. Computed tomography demonstrated a dilated small bowel loop in the Douglas's fossa,but no definite diagnosis could be made. Supportive therapy with draining the intestinal fluid by a long intestinal tube did not result in improvement,which suggested the possibility of a strangulated hernia. Exploratory laparotomy revealed mobile cecum and a 20-cm length of the ileum herniated into a defect of the right broad ligament. As a gangrenous change was recognized in the incarcerated bowel, its resection was carried out,followed by end-to-end anastomosis and closure of the defects of the broad ligament. The postoperative course was uneventful. Intestinal obstruction is a very common cause for presentation to an emergency department,while internal hernia is a rare cause of obstruction. Among internal hernias, those through defects of the broad ligament are extremely rare. Defects of the broad ligament can be either congenital or secondary to surgery, pelvic inflammatory disease,and delivery trauma. In conclusion, we emphasize that hernia of the broad ligament should be added to the list of differential diagnosis for female patients presenting with an intestinal obstruction. Early diagnosis and surgical repair reduce morbidity and mortality from strangulation.

RESUMO

Boron adsorption onto activated sludge was investigated using bench-scale reactors under simulated wastewater treatment conditions. Two experiments, continuous flow and batch, were performed. Boron concentrations were determined by means of inductively coupled plasma mass spectrometry. The results of the continuous-flow experiment indicated that a small amount of boron accumulated on the activated sludge and its concentration in the sludge depended on the nature of the biota in the sludge. Freundlich and Langmuir isotherm plots generated using the data from the batch experiment indicated that boron was adsorbed onto rather than absorbed into the sludge. The Freundlich constants, k and 1/n, were determined to be 26 mg/kg and 0.87. These values indicate that activated sludge has a limited capacity for boron adsorption and thus utilization of the excess sludge for farmland may not be toxic to plant at least boron concern.

RESUMO

One-stage surgical management of concomitant abdominal aortic aneurysm (AAA) and gastric or colorectal cancer should provide certain benefits. We reviewed the records of 21 patients with both AAA and gastric or colorectal cancer who underwent one-stage surgical management. Four had distal gastrectomy, 2 had total gastrectomy, and 5 had abdominoperineal rectal resection transperitoneally; 3 had total gastrectomy transperitoneally and AAA repair extraperitoneally. Two underwent right hemicolectomy and thromboexclusion of the AAA. Two had creation of a temporary ileostomy and implantation of an interposition graft. Two underwent left hemicolectomy, creation of a temporary transversostomy, and implantation of an interposition graft. One had a Hartmann's procedure and implantation of a bifurcated prosthetic interposition graft for AAA. There were no operative deaths or serious postoperative complications. One patient had colorectal ischemia that resolved with conservative treatment. Eighteen of the 21 patients (85.7%) were alive 10 months to 14 years postoperatively. In conclusion, one-stage surgical treatment of concomitant AAA and gastric or colorectal cancer is well tolerated and can avoid the time, financial costs, and patient anxiety involved in a second operation.
