Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

PURPOSE: To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. MATERIALS AND METHODS: We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. RESULTS: On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gasshadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer infour cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focallow density lesion suggestive of focal abscess was not visualized. CONCLUSION: Plain radiography is useful forearly diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.

A 50-year-old man who had suffered from chronic indigestion complained of upper abdominal pain and vomiting which had persisted for 4 days. Consequently, he had eaten two persimmons before sleeping detected each day for five days. An irregular multinodular villous filling defect was in the duodenal bulb on, the UGI series, which had its location and changed its position. It was difficult to differentiate a papillary gastric polyp or villous tumor from the duodenal bezoar, but the patient's history of having eaten persimmons was helpful. The endoscopic and pathologic study confirmed a phytobezoar which was located in the normal duodenal bulb. Subsequently we are reporting this case having reviewed the related literature of the phytobezoar which was found in the normal duodenal bulb.

PURPOSE: To evaluate the usefulness of CT scanning in determining the etiology of spontaneous rupture of the kidney. MATERIALS AND METHODS: We retrospectively analyzed the CT findings of spontaneous rupture of the kidney in eleven patients, Four were male and seven were female, and they were aged between 20 and 71 (mean, 46.6) years. Both pre- and post-contrast enhanced CT scanning was performed in all patients. RESULTS: Spontaneous renal rupture was induced in seven cases by neoplasms (three angiomyolipomas, three renal cell carcinomas, and one metastatic choriocarcinoma), in three cases by infection or inflammation (acute and chronic pyelonephritis, and renal abscess), and in one, by renal cyst. Common CT findings of rupture of the kidney were the accumulation of high density fluid in the perirenal and anterior pararenal space, and in homogeneous irregular low density of renal parenchyma and the rupture site. Angoimyolipoma showed fat and an angiomatous component in the lesion, while acute and chronic pyelonephrities revealed thinning of the renal parenchyma and an irregular renal outline. Renal cell carcinoma showed a dense soft tissue mass in the parenchyma. Well-defined, round low-density lesions were noted in the case of renal cyst and renal abscess. CONCLUSION: CT is very useful in diagnosing and determining the etiology of non-traumatic spontaneous rupture of the kidney and plays an important role in the evaluation of emergency cases.

PURPOSE: To evaluate the usefulness of endoanal ultrasonography and to determine the imaging features of patients with fecal incontinence, anal abscess or anal fistula. MATERIALS AND METHODS: Twenty five patients underwent endoanal ultrasonography between October 1995 and July 1996. Ten of these were fecal incontinence cases, eight had an anal abscess, and seven, an anal fistula. The incontinence grading scale (IGS) was used for clinical grading of fecal incontinence and pudendal nerve terminal motor latency (PNTML) for pudendal nerve injury. Endoanal ultrasonographic features and operative findings were retrospectively reviewed. RESULTS: Endoanal ultrasonography revealed defective sphincteric muscles in all three patients with myogenic fecal incontinence, but in six of seven cases with neurogenic fecal incontinence, these muscles were not defective. Myogenic and neurogenic incontience showed different findings (p=0.033). In comparison with surgical findings, endoanal ultrasonography was 88% accurate in anal abscess cases and 86% accurate in those of anal fistula. CONCLUSION: Endoanal ultrasonography in conjunction with PNTML was very useful for the detection of the site and severity of sphincteric muscle defect and diagnosis of the etiology of fecal incontinence. Through analysis of the site and type of lesion, the procedure can also serve as a guide to the surgical treatment of patients with anal abscess or fistula.

Tuberculosis of the cystic duct lymph node is very rare. Only four cases have been reported in the literature. This paper presents the case of a young male patient with a tuberculous cystic duct lymph node and chronic cholecystitis, who was diagnosed with cystic duct stones and a gall bladder polyp preoperatively.

Methyl salicylate is widely used in various topical products, including sports creams, ointments, patches, and oral hygiene products. These products are mainly used for localized treatment of musculoskeletal pain. Given their intended topical application, their ingestion can result in salicylic acid poisoning due to their high concentrations of methyl salicylate. Symptoms of salicylic acid poisoning may include dizziness, vomiting, hallucinations, seizures, and, in severe cases, unconsciousness, respiratory failure, and circulatory disorders. We report a case of a 71-year-old male who ingested Mensolatum Lotion to commit suicide and died.

PURPOSE: Previous retrospective studies suggest that anaplastic lymphoma kinase (ALK) mutation-positive (ALK+) non-small cell lung cancer (NSCLC) patients are sensitive to pemetrexed. To determine its efficacy, we retrospectively evaluated clinical outcomes of pemetrexed-based chemotherapy in patients with ALK+ NSCLC. MATERIALS AND METHODS: We identified 126 patients with advanced, ALK+ NSCLC who received first-line cytotoxic chemotherapy. We compared response, progression-free survival (PFS), and overall survival (OS) rates according to chemotherapy regimens. Furthermore, we evaluated intracranial time to tumor progression (TTP) and proportion of ALK+ cells as prognostic factors. RESULTS: Forty-eight patients received pemetrexed-based chemotherapy, while 78 received other regimens as first-line treatment. The pemetrexed-based chemotherapy group showed superior overall response (44.7% vs. 14.3%, p < 0.001) and disease control (85.1% vs. 62.3%, p=0.008) rates. The pemetrexed-based chemotherapy group also exhibited longer PFS (6.6 months vs. 3.8 months, p < 0.001); OS rates were not significantly different. The lack of exposure to second-generation ALK inhibitors and intracranial metastasis on initial diagnosis were independent negative prognostic factors of OS. Intracranial TTP was similar between the treatment groups (32.7 months vs. 35.7 months, p=0.733). Patients who harbored a greater number of ALK+ tumor cells (≥70%) showed prolonged OS on univariate analysis (not reached vs. 44.8 months, p=0.041), but not on multivariate analysis (hazard ratio: 0.19, 95% confidence interval: 0.03–1.42; p=0.106). CONCLUSION: Pemetrexed-based regimens may prolong PFS in patients with ALK+ NSCLC as a first-line treatment, but are not associated with prolonged OS. Exposure to second-generation ALK inhibitors may improve OS rates in patients with ALK+ NSCLC.

BACKGROUND/AIMS: An association between obesity and erosive esophagitis has been reported, but the effects of sarcopenia and obesity on erosive esophagitis are unknown. This study examined the relationship between obesity, sarcopenia, sarcopenic obesity, and erosive esophagitis in a large population of asymptomatic men and women.METHODS: This study analyzed 32,762 subjects who underwent a comprehensive health check-up, which included upper gastrointestinal endoscopy, from August 2006 to December 2011 by a cross-sectional study. Sarcopenia was defined as a decrease in the appendicular skeletal muscle mass (ASM)/body weight value of two SD or more below the normal means for a younger reference group.RESULTS: The study was carried out on four groups according to obesity and sarcopenic status: normal, obesity, sarcopenic, and sarcopenic obese group. In a multivariable model, the risk of erosive esophagitis was higher in the obese (adjusted OR [aOR] 1.35, 95% CI 1.22–1.49), sarcopenic (aOR 2.12, 95% CI 1.40–3.19), and sarcopenic obese groups (aOR 1.54, 95% CI 1.27–1.87) than in the normal group. The risk of erosive esophagitis was higher in the sarcopenic and sarcopenic obese groups than the obese group; the ORs were 1.63 (95% CI 1.08–2.47) and 1.22 (95% CI 1.01–1.46), respectively. In dose-response analysis, increasing sarcopenia severity showed a positive and graded relationship with the overall, Los Angeles (LA)-B or higher grade, and LA-C erosive esophagitis.CONCLUSIONS: This study suggests that sarcopenia is strongly and progressively associated with erosive esophagitis.
