A 16-month-old boy swallowed accidentally a button type lithium battery with diameter 23 mm. The battery impacted at the upper esophagus was removed by endoscpy in 9 hours. At the time of removal, dark-crust and erythematous mucosal lesion was noted where the battery impacted. At the first hospital day, fever over 38.5 degrees C developed, and NPO, antibiotics and H-2 blocker started. At the third hospital day, he had melena, and endoscopy revealed huge active esophageal ulceration ranging from upper esophagus and lower body of the esophagus. Steroid started. At the 10th hospital day, endoscopy revealed much smaller-sized ulceration, but mucosa where the battery impacted initially showed deep depression which might imply developing diverticulum. At the 17th hospital day, endoscopy revealed complete diverticulum. At the 27th hospital day, endoscopy revealed complete resolution of diverticulum.

PURPOSE: The rate of malignancy in the follicular neoplasm (FN) or Hürthle cell neoplasm (HCN) of the thyroid gland is estimated as approximately 20~30%. Fine-needle aspiration biopsy (FNAB) and frozen section examination are restricted in differentiating between benign and malignant. The aims of this study are to compare the differences of clinicopathologic features and to determine the risk factors for malignancy in patients with FN or HCN. METHODS: A retrospective study was conducted of patients with FN or HCN who were diagnosed by FNAB, and underwent surgery at our institution between Jan. 2005 to Jun. 2010. We analyzed the risk factors for malignancy and the differences of clinicopathologic features in patients with FN or HCN. RESULTS: A total of 290 patients were enrolledin this study; 160 (55.2%) patients underwent thyroidectomy, 97 (60.6%) patients had FN, and 63 (39.4%) had HCN. Forty one (25.6%) patients were diagnosed as malignancy of these, 22 (22.7%) patients were FN and 19 (30.2%) were HCN (P=0.29). Two (2.1%) patients with FN and 10 (15.9%) with HCN (P=0.002) comcomitant papillary thyroid carcinoma were indentified by FNAB. Classification of nodules according to ultrasonographic findings in both neoplasms (P<0.05) and galectin-3 in FN (P<0.05) were predictive factors for malignancy. In addition, galectin-3 was a predictive factor for malignancy in indeterminate nodules on ultrasonography (USG) (P=0.028). CONCLUSION: Classification of nodules according to ultrasonographic findings and galectin-3 expression is helpful in predicting carcinoma of patients with FN or HCN.

The elucidation of the molecular mechanisms underlying the differentiation and proliferation of human adipose tissue-derived stromal cells (hADSCs) represents a critical step in the development of hADSCs-based cellular therapies. To examine the role of the microRNA-103a-3p (miR-103a-3p) in hADSCs functions, miR-103a-3p mimics were transfected into hADSCs in order to overexpress miR-103a-3p. Osteogenic differentiation was induced for 14 days in an osetogenic differentiation medium and assessed by using an Alizarin Red S stain. The regulation of the expression of CDK6 (cyclin-dependent kinase 6), a predicted target of miR-103a-3p, was determined by western blot, real-time PCR and luciferase reporter assays. Overexpression of miR-103a-3p inhibited the proliferation and osteogenic differentiation of hADSCs. In addition, it downregulated protein and mRNA levels of predicted target of miR-103a-3p (CDK6 and DICER1). In contrast, inhibition of miR-103a-3p with 2'O methyl antisense RNA increased the proliferation and osteogenic differentiation of hADSCs. The luciferase reporter activity of the construct containing the miR-103a-3p target site within the CDK6 and DICER1 3'-untranslated regions was lower in miR-103a-3p-transfected hADSCs than in control miRNA-transfected hADSCs. RNA interference-mediated downregulation of CDK6 and DICER1 in hADSCs inhibited their proliferation and osteogenic differentiation. The results of the current study indicate that miR-103a-3p regulates the osteogenic differentiation of hADSCs and proliferation of hADSCs by direct targeting of CDK6 and DICER1 partly. These findings further elucidate the molecular mechanisms governing the differentiation and proliferation of hADSCs.

Plasma cholinesterase (ChE), an enzyme produced by the liver, rapidly hydrolizes succinylcholine. In the presence of low enzymatic activity, the rate of destruction of succinylcholine is diminished and it may result in an undesirably long duration of paralysis following succinylcholine administration. There are many reports that a significant fall in plasma ChE activity was shown to occur during pregnancy and in the immediate postpartum period. The present study was designed to compare the plasma ChE activity and the reaction of succinylcholine in 27 healthy nonpregnant women with that in 30 pregnant women undergoing elective caesarean section. Before induction of anesthesia, venous blood was taken for the measurement of plasma ChE activity, which was assayed by a colorimetric method, and the duration of action, recovery index and TOF ratio of succinylcholine were measured using ABM (Anesthesia and Brain activity Monitor, Datex Co.). The results were as follows: 1. Plasma ChE aetivity in pregnant women was lower than in nonpregnant women but was not statistically significant. 2. With respect to the duration of action, recovery index and TOF ratio on the 25 and 75% recovery of first twitch height, there were no significant differences between pregnant and nonpregant women.

Holoprosencephaly is a rare malformation complex or development defect including different degrees of incomplete cleavages of the embryonic prosencephalon and varying degrees of the midface defects, resulting from the defect of prechordal mesoderm, migrating forward into the area anterior to the notochord during the third week of fetal development. Early antenatal diagnosis of holoprosencephaly is important to find out its severity, to predict its prognosis, and to determine proper management according to its prognosis and severity. The possibility of early antenatal diagnosis of holoprosencephaly by ultrasound has been suggested, but occasionally missed and rarely confirmed. We present one case of lobar holoprosencephaly, diagnosed postnatally and one case of alobar holoprosencephaly, diagnosed antenatally in our hospitals.

PURPOSE: To determine through an analysis of the location of pleural effusion associated with ascites, as seen on abdominal CT scan, differences in the distribution of pleural effusion according to the etiology and distribution of ascites. MATERIALS AND METHODS: We retrospectively evaluated 77 consecutive patients in whom abdominal CT scan revealed pleural effusion associated with ascites. Patients with history of surgery or trauma and those with clinically and radiologically diagnosed lung or pleural diseases were excluded. We compared the location of pleural effusion with the etiology and distribution of ascites. RESULTS: Forty-two patients were suffering from hepatobiliary diseases, mainly right dominant pleural effusion (26/42, 62%). Fourteen had intraperitoneal carcinomatosis with no significant difference between the frequency of right dominant (5/14, 36%)and of left dominant (6/14, 43%) pleural effusion. Eleven patients had pancreatic diseases, with mainly left dominant pleural effusion (6/11, 55%). Patients with right dominant ascites usually had right dominant pleural effusion (22/24, 92%) and those with left dominant ascites had left dominant pleural effusion (9/10, 90%). CONCLUSION: Ascites-associated pleural effusion correlated with the anatomical location of the etiology of ascites ; its laterality was, in addition, usually the same as that of ascites.

Tuberculous uveitis is a rare manifestation of tuberculosis infection. Although early diagnosis is important to saving the sight of patients, it is difficult. In dialysis patient, the diagnosis of tuberculosis is often delayed because of non-specific symptoms and extrapulmonary involvements. We report a case involving a 37-year-old man receiving hemodialysis who was presented with persistent fever and left- sided blurred vision. At ophthalmic examination, active papillitis, vitritis, and peripapillary retinal detachment were observed. Neck computed tomography showed multiple necrotic lymphadenopathies (LAPs) in right lateral neck, which was proven as tuberculous lymphadenitis on histological examination. After anti-tuberculosis therapy, fever was subsided and LAPs were improved. Visual acuity was also improved.
