Obstructive jaundice produced by periportal tuberculous adenitis in the absence of pulmonary tuberculosis is quite rare. We are reporting the case of a 58-year-old woman who presented with constitutional symptoms and biochemical evidence of biliary tract obstruction. By abdominal sonogram and CT scan, a mass around the head of pancreas and periportal area was detected. The ERCP showed fistula connected proximal common bile duct to lymph node. The patient underwent laparotomy and recognized tuberculous adenitis of periportal lymph node which caused biliary tract obstruction with fistula.

OBJECTIVES: Using 3-stimulus auditory "oddball" paradigm reflecting fronto/central and temporo/parietal functions simultaneously, we examined patients with schizophrenia. METHODS: Fifteen patients with schizophrenia from outpatient clinic and fifteen normal controls from hospital staffs were recruited for the study. To elicit P3a and P3b, 3-stimulus auditory oddball paradigm was employed. The 3-stimulus auditory oddball paradigm was composed of standard tone (1,000 Hz, 75 dB, 80%), target tone (2,000 Hz, 75 dB, 10%) and distracter (White noise, 95 dB, 10%). RESULTS: P3a and P3b were prominent in fronto/central and temporo/parietal areas, respectively, in both schizophrenics and normal controls. The P300 amplitude in patients with schizophrenia was reduced across P3a and P3b (p<0.01). The P300 latency in patients with schizophrenia was delayed across P3a and P3b (p<0.01). CONCLUSION: These results were consistent with frontal and temporo-parietal lobe dysfunctions in schizophrenics. The 3-stimulus auditory paradigm could be applied for patients with schizophrenia and useful for further exploration the disorder.

The dysregulation of the dopaminergic system has been implicated in the pathophysiology of major psychosis, including schizophrenia, with dopamine receptor genes (DRDs) presently targeted as the most promising candidate genes. We investigated DRD1-5 for association with schizophrenia using a multi-stage approach in a Korean sample. One hundred forty-two SNPs in DRD1-5 were selected from the dbSNP, and the associations of each SNP were then screened and typed by MALDI-TOF mass spectrometry using pooled DNA samples from 150 patients with major psychosis and 150 controls. Each of the suggested SNPs was then genotyped and tested for an association within the individual samples comprising each pool. Finally, the positively associated SNPs were genotyped in an extended sample of 270 patients with schizophrenia and 350 controls. Among the 142 SNPs, 88 (62%) SNPs in our Korean population were polymorphic. At the pooling stage, 10 SNPs (DRD1: 2, DRD2: 3, and DRD4: 5) were identified (P < 0.05). SNPs rs1799914 of DRD1 (P = 0.046) and rs752306 of DRD4 (P = 0.017) had significantly different allele frequencies in the individually genotyped samples comprising the pool. In the final stage, with the extended sample, the suggestive association of DRD4 with rs752306 was lost, but the association of DRD1 with rs1799914 gained greater significance (P = 0.017). In these large-scale multi-stage analyses, we were able to find a possible association between DRD1 and schizophrenia. These findings suggested the potential contribution of a multi-step strategy for finding genes related to schizophrenia.

OBJECTIVES: Gamma-aminobutyric acid (GABA) has potential benefits in counteracting the sleep disruption and potential therapeutic effects on blood pressure, stress, cancer, and inflammatory diseases. Recently, High-dose GABA can be extracted from fermented rice germ using lactic acid bacteria. This study aimed to evaluate the effects of GABA natural extracts from fermented rice-germ on sleep latency, subjective sleep quality and insomnia symptoms. METHODS: This was a prospective randomized double-blind placebo-controlled trial performed at Kyung-Hee University hospital at Gangdong from June 2013 to October 2013. Adult (age≥30) patients who was diagnosed of insomnia according to DSM-IV criteria was enrolled. They were randomized into three groups: high dose treatment group 300 mg; low-dose treatment group, 100 mg; and placebo group. Questionnaires including Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), WHO-5 Well-Being Index were performed, and 1-week actigraphy was recorded before and 1 week after the treatment. RESULTS: Total of 114 patients were randomized into 3 groups: high-dose treatment (n=37), low-dose treatment (n=38), and placebo treatment group (n=39). At 1 week after the treatment, PSQI total score and C2 (sleep latency) score significantly decreased in low-dose and high-dose treatment group than the placebo groups [Repeated measures analysis of variance (ANOVA), p=0.017, 0.004 respectively]. ISI score also decreased in the two groups in dose-dependent manner (Repeated measures ANOVA, p=0.037). There were five (4.4%) patients who reported medication adverse events. CONCLUSIONS: This study suggests that treatment of low and high-dose GABA from unpolished rice-germ decreases sleep latency and improve insomnia severity without severe adverse events.

Epithelioid hemangioendothelioma (EH) is a rate pulmonary vascular malignancy. Clinically, EH has been considered as an indolent, generally non-aggressive tumor. We report a case of EH which was confirmed by open lung biopsy. A 34-year-old woman was admitted for further evaluation of multiple small (less than 2cm in size) nodules, incidentally detected on screening chest radiograph. The chest CT showed multiple, relatively well-marginated, variable sized nodules at both whole lung. Transbronchial lung biopsy and transthoracic needle aspiration were nondiagnostic and open lung biopsy was performed from right middle lobe of lung. On light-microscopic examination, the nodules were composed of a poorly cellular hyaline core and a more cellular peripheral zone which extended into air space in a micropolypoid fashion and obliterated blood vessels. The tumor cells at the peripheral zone had intracytoplasmic vacuoles which suggested primitive, vascular differentiation. Immuno-histochemical study revealed the cellular area which gave positive reaction to factor VIII-related antigen. She received no specific therapy after open lung biopsy and chest X-ray films had showed no change for about two years.

PURPOSE: The purpose of this study was to evaluate the clinical characteristics of children who had been diagnosed as specific language impairment as outpatients. METHODS: One hundred twenty-five speech- or language-delayed patients were enrolled in Dae-Dong Hospital from July 2007 to June 2008. Fifty-one of 125 children were diagnosed as specific language impairment in whom clinical factors such as duration of therapy and progress after therapy were evaluated. Data were obtained from telephone or direct personal interviews. RESULTS: Among 51 children diagnosed as specific language impairment, 39 (76.5%) had mixed receptive-expressive-type language disorder and 12 (23.5%) had expressive-type language disorder. Thirty children in total were studied as ten children were unavailable for follow-up and eleven dropped out during treatment. The final 30 children consisting of 23 with mixed receptive-expressive type language disorder and seven children with expressive-type language disorder were treated after diagnosis. Total average treatment duration of children with mixed receptive-expressive-type and expressive-type language disorder were 18.1 months and 8.6 months, respectively, a statistically significant difference (P = 0.014). Thirteen (57%) of 23 children with mixed receptive-expressive-type language disorder and all (100%) seven children with expressive-type language disorder completed speech therapy with an average treatment duration of 12.2 and 8.6 months, respectively; however, this difference was not statistically significant(P = 0.287). CONCLUSION: Classifying patients with specific language impairments into mixed receptive-expressive-type and expressive-type language disorder in an outpatient department can be useful for predicting duration of and prognostic effects of language therapy, as our study and other previous articles have shown. More attention is needed from pediatricians to ensure the effective assessment and management of specific language impairment.

OBJECTIVES: Nowadays most infants on exclusively breast feeding have vitamin D deficiency due to the increase of breast feeding. However, domestic research lacks appropriate materials. Therefore, we researched practical clinical aspects of vitamin D deficiency related to breast milk feeding for infants who have a high amount of alkaline phosphatase (> 500 IU/L). METHODS: The subjects of the study were 31 infants with high alkaline phosphatase level. We tested with 25-hydroxycholecalciferol (25-OHD3), parathyroid hormone, calcium, ionized calcium, phosphorus in their blood and with a wrist x-ray. Then, we divided them into two groups of breast feeding and formula feeding and compared the results. RESULTS: Eighteen infants (58%) out of 31 infants that have high alkaline phosphatase were vitamin D insufficiency or deficiency, and 16 (100%) breast feeding infants of them showed vitamin D deficiency or insufficiency. However, only 2 (13%) of 15 formula feeding infants were at insufficiency. There was a correlation between alkaline phosphatase and 25-OHD3 concentration in multiple regression analysis, but no correlation in other variables was found in group of breast milk feeding infants. There was neither correlation between vitamin D concentration and alkaline phosphatase nor other correlated variables in the group of formula milk feeding infants. CONCLUSIONS: In this study, there was a high probability of vitamin D deficiency in the breast feeding infants with a high alkaline phosphatase level. Therefore, it is considered to be worth utilizing alkaline phosphatase as a screening test for vitamin D deficiency or rickets for breast feeding infants.

The authors calculated the number of blood cultures per 1,000 admitted patient days at seven university-affiliated hospitals in 2010, which ranged from 65 to 129 (mean 110). The number of blood cultures per 1,000 patient days could possibly be a good parameter for assessing the appropriateness of blood culture.
