As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

Milk of calcium located in the breast is typically a benign entity. However, carcinoma may incidentally arise adjacent to or even within milk of calcium. Consequently, the characteristics of all observed calcific particles should be carefully analyzed. In this study, we report a case of carcinoma presented as malignant microcalcifications mixed within milk of calcium in a breast.

The internal biliary fistula between the gallbladder or bile duct and intestinal tract is a rare disease. Because symptoms and signs of biliary fistula are not specific, these patients are commonly investigated with computed tomography, endoscopic retrograde cholangiopancreatography (ERCP) and barium study. Among them, a cholecystogastric fistula is a very rare type of biliary fistula. We recently experienced a case of cholecystogastric fistula and transmigration of the gallstone to the stomach. A 53-year-old woman was transferred with the impression of gallbladder cancer. On evaluating the cause of right upper abdominal pain and nausea, we confirmed the cholecystogastric fistula with gastroscopy, upper GI series and ERCP. Cholecystectomy and the repair of the fistula was done.

BACKGROUND: Adiponectin is a fat cell-secreted cytokine, which has been reported to improve insulin sensitivity and have antiatherogenic properties. However, it is still unclear whether resistin plays a significant role in the development of insulin resistance in humans. The aim of this study was to investigate the relationship of the adiponectin and resistin concentrations with insulin resistance, metabolic markers and adiposity in healthy and type 2 diabetic subjects. METHODS: Eighty-three type 2 diabetic and 139 healthy subjects were studied. Blood samples were drawn after fasting to determine the fasting plasma glucose, insulin, resistin, adiponectin, total cholesterol, triglyceride and HDL-cholesterol levels. The subcutaneous and visceral fat areas were measured at the umbilical level using computed tomography. RESULTS: The serum adiponectin concentrations were significantly lower in the diabetic(6.7+/-2.3microgram/mL) than in the obese(8.2+/-2.4microgram/mL, P<0.01) and non-obese subjects(9.9+/-4.5microgram/mL, P<0.01). The serum resistin concentrations were Similar between the non-obese, obese and type 2 diabetic subjects. From a multiple regression analysis, the fasting glucose, HDL-cholesterol and HOMA-IR were found to be independent determinants of the log of the adiponectin level in the diabetes group. In healthy subjects, the gender, BMI, HOMA-IR, visceral fat area and HDL-cholesterol were associated with the log of the adiponectin level. However, the log of the resistin level was not associated with the markers of insulin resistance and obesity. CONCLUSION: This study showed that the serum adiponectin concentration was closely related to the insulin resistance marker in both healthy and type 2 diabetic subjects. However, the resistin concentration was not associated with the markers of insulin resistance and/or obesity.

BACKGROUND: Spinal muscular atrophy (SMA) is the second most common disease with autosomal recessive mode of inheritance in children and characterized by degeneration of anterior horn cells of the spinal cord resulting in weakness and wasting of voluntary muscles. This disease is caused by deletion of many candidate genes including SMN, p44, NAIP on chromosome 5q11.2-13.3. Although molecular characteristics of candidate genes were identified, genotype-phenotype correlation has not been clearly elucidated yet. Nevertheless, gene conversion, previously described as simply as gene deletion, appears to be very important mechanism as a molecular pathogenesis, and even makes more difficult to pursue the correlation. PURPOSE: This study was aimed to define the correlation between genotype and phenotype of SMA in Korean patients. The significance of SMN gene as well as NAIP gene, p44 gene in the progress of disease process and phenotypic correlation with gene conversion was evaluated. This study was also undertaken to determine the frequency of gene rearrangements in normal population. METHOD: Eight type I SMA patients and two type II SMA patients were studied. SMN, NAIP, and p44 gene deletion were analyzed by PCR amplification and restriction enzyme digestion with DraI, DdeI and AluI, respectively. p44 gene was also analyzed by SSCP. Gene conversion was defined by centromeric and telomeric SMN gene exon 7 to exon 8 PCR amplification followed by DdeI restiction enzyme digestion. RESULT: 1) Five of eight type I patients showed deletion of SMN, NAIP and p44 gene, while the rest of type 1 and all type II patients showed deletion of SMN gene only. 2) We examined SMN and NAIP gene deletion on 100 normal newborns, which showed the deletion of centromeric SMN gene in two newborns, the relative frequency of 2% in gene rearrangement. 3) There was one case of type I SMA showing deletion of telomeric SMN exon 7 but not SMN exon 8 suggestive of gene conversion occurred during the recombination as a molecular pathogenesis. CONCLUSION: The major deletion of SMA candidate genes, SMN, NAIP, and p44 gene appear to be involved in severe phenotype since these three candidate genes deletion were noted only in type 1 cases. However, SMN gene deletion only identified both in type 1 and type 2 explains that SMN gene may plan an major role in the pathogenesis of SMA and also suggests that other factors may be affecting the severity in spinal muscular atrophy. One patient with type I which showed the conversion of the centromeric SMN gene to the teleomeric gene strongly supports that SMN gene copy number may not be correlated with the severity in SMA. Our molecular findings suggest that phenotype is not clearly correlated with genotype. Prenatal screening should be carefully undertaken to interpretate because of high frequency of gene rearrangements in normal populations.

PURPOSE: To assess the applicability of quantitative MR microscopy for the detection of glycosaminoglycan (GAG) depletion as an early sign of degeneration in the articular cartilage of humans treated by trypsin. MATERIALS AND METHODS: Four cartilage-bone blocks were obtained from the patient who had suffered from osteoarthritis of the knee and underwent a total knee replacement arthroscopy. Each articular cartilage segment was resected as to a round disk shape (8 mm in diameter) with a remnant of subchondral bone 1 mm in thickness. Four different culture solutions were prepared, and these solutions were 0.2 mg/ml of trypsin solution (group 1), 1 mM of Gd (DTPA) 2-mixed trypsin solution (group 2), phosphate buffered saline (PBS) (group 3), and 1 mM of Gd (DTPA) 2-mixed PBS (group 4). The cartilages were cultured and then MR imagings were performed every hour for 5 hrs, and we continued the additional cultures of 24 hrs, 36 hrs and 48 hrs. Three imaging sequences were used: T1-weighted spin echo (TR/TE, 450/22), proton density turbo spin echo with fat suppression (TR/TE, 3000/25), and CPMG (Carr-Purcell-Meiboom-Gill) (TR/TE/TI, 760/21-168, 360). MR imaging data were analyzed with pixel-by-pixel comparisons in all groups. RESULTS:The GAG loss in the articular cartilage was increased proportionately to the culture duration. Mean changes of T1 relaxation time were 1.2% for group 1, -1.9% for group 3, -54.7% for group 2 and -64.2% for group 4 (p<0.05). When comparing by linear profile on the T1-weighted images, SNR increased and T1 relaxation time decreased for group 2 and 4, as the culture duration increased (p<0.05). On the correlation analysis, there is significant correlation between GAG loss and Gd (DTPA) 2-enhancement for group 2 (p=0.0431), but there was no significant difference for group 4 (p=0.0918). More enhancement with Gd (DTPA) 2-was noted for group 2 than for group 4. Group 2 showed a diffuse enhancement in all the layers of cartilage, but for group 4, prominent enhancement was noted only in the superficial layer. CONCLUSION: Early degenerative changes of the articular cartilage were not noted on the T1-weighted images, turbo spin echo with fat suppresison and T1, T2, or the rho relaxometry by a 1.5 T machine. Only Gd (DTPA) 2- enhancement was useful in the detection of early degeneration of the articular cartilage.

Although failure of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKI) is generally believed to be associated with cross-resistance to other EGFR TKI, the benefit of administering erlotinib as a second EGFR TKI after resistance of gefitinib as the first TKI has been well known. However, good response to gefitinib after an initial response to erlotinib has been rare. We report that a 45-year-old woman (never smoked), with lung adenocarcinoma and EGFR mutation, showed an initial response to erlotinib, and then responded to gefitinib again.
