It is often problematic to diagnose T-cell lymphoproliferative disorders of the skin because of the difficulty in establishing clonality in paraffin-embedded tissue. We used polymerase chain reaction single strand conformational polymorphism (PCR-SSCP) and heteroduplex analysis in paraffin embedded tissue to detect clonal rearrangement of T-cell receptor gamma (TCRgamma) gene in 17 T-cell lymphoproliferative disorders and 6 atypical lymphoproliferative diseases. We used polymerase chain reaction to detect TCR beta gene rearrangement in 8 of 17 cases which did not show TCRgamma gene rearrangement. Jurkat cell lines were used as monoclonal controls. DNA was extracted from 5 biopsies of T-cell lymphomas, 10 biopsies of mycosis fungoides, 2 biopsies of lymphomatoid papulosis, and 6 biopsies of atypical lymphoproliferative lesions. We detected monoclonality in 5 of 5 T-cell lymphoma cases, 2 of 2 lymphomatoid papulosis cases, 6 of 10 mycosis fungoides cases, and 2 of 6 atypical lymphoproliferative disease cases. We conclude that nonradioactive PCR-SSCP for TCR gene rearrangement analysis is a useful adjunct to routine histological and immunophenotypic methods in the diagnosis of cutaneous T cell lymphoproliferative disorders in paraffin embedded tissue.

We report a unique case of synchronous double primary gastric cancer consisting of adenocarcinoma components with micropapillary features and composite glandular-endocrine cell carcinoma components. The patient was a 53-year-old man presenting with a 6-month history of epigastric pain and diarrhea. A subtotal gastrectomy was performed. Histologically, one tumor was composed of micropapillary carcinoma components (50%) with tight clusters of micropapillary aggregates lying in the empty spaces, admixed with moderately differentiated adenocarcinoma components. MUC-1 was expressed at the stromal edge of the micropapillary component. The other tumor was composed of atypical carcinoid-like neuroendocrine carcinoma (50%), adenocarcinoid (30%), and adenocarcinoma components (20%). The neuroendocrine components were positive for CD56, synaptophysin, chromogranin, and creatine kinase. The adenocarcinoid components were positive for both carcinoembryonic antigen and neuroendocrine markers (amphicrine differentiation). This case is unique, due to the peculiar histologic micropapillary pattern and the histologic spectrum of adenocarcinoma adenocarcinoid-neuroendocrine carcinoma of the synchronous composite tumor.

Dopamine has long time considered as the main player in drug addiction. However, growing body of literature strongly supports a role for glutamate in addiction. 2-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors, one of the ionotropic glutamate receptors, are known to be involved in different forms of synaptic plasticity, and behaviors such as learning and memory. As drug addiction is a chronic brain disease with characteristics of craving and relapse, it is often considered as a maladapted form of drug-induced long-term memory. Experimental evidence strongly indicates that AMPA receptor has an important role in the development of drug addiction. Studies with animal models of drug addiction, such as behavioral sensitization and drug self-administration, demonstrate that AMPA receptor-mediated synaptic plasticity may underlie the neuronal mechanisms for such important characteristics of addiction as drug craving.

PURPOSE: The purpose of this study was to describe sexual behavior and understand the correlation between knowledge and attitude of contraception and provide preliminary data to develop a sex education program. METHOD: The subjects of this study were 400 university students. Data was collected from November 14 to 20,2005 by using structured questionnaires. RESULT: The percent of subjects that experienced sexual intercourse was 32%. The respondents' score of knowledge of contraception was a mean score of 15.33 on a scale of 20 and there were significant differences in major departments, existence or nonexistence of sexual intercourse and sexual knowledge. The respondents' score of attitude of contraception was a mean score of 40.98 on a scale of 60 and there were significant differences in sex. There was no significant correlation between knowledge and attitude of contraception. CONCLUSION: A sex education program that uses practical knowledge and attitude of contraception to prevent conception should be developed rather than the present sex education that only attaches schoolbook knowledge.

PURPOSE: T2 gastric cancer is tumor invading proper muscle or subserosal layer. The 2002 American Joint Committee on Cancer subdivided the pT2 gastric adenocarcinoma into a type pT2a (invasion of the proper muscle) and a type pT2b (invasion of the subserosa). The aim of this study was to evaluate the differences between pT2a and pT2b gastric cancers of the clinicopathological features and the prognostic factors. METHODS: A series of curative operations were performed on 194 patients with pT2 gastric cancer from January 1999 to February 2006. We reviewed, retrospectively, the clinicopathologic characteristics, the 3-year disease free survival and the 5-year disease specific survival rates. RESULTS: There were significant clinicopathologic differences between pT2a and pT2b gastric cancer in tumor size and the number of metastatic lymph nodes. Both of the 3-year disease free survival time and the 5-year disease specific survival time were much longer for the pT2a gastric carcinoma patients than those for the pT2b gastric carcinoma patients. CONCLUSION: It is important to consider the differences between pT2a and pT2b gastric cancers for prediction of recurrence or prognosis. Furthermore, new staging of pT2a and pT2b cancer may be necessary.

Abdominal compartment syndrome (ACS) is a life-threatening disorder caused by rapidly increasing intraabdominal pressure. ACS can result in multiorgan failure and carries a mortality of 60~70%. The treatment of choice in ACS is surgical decompression. There are very few reports of ACS and experience in Korea. We report 12-year-old male patient who developed an abdominal compartment syndrome due to traffic-accident-induced retroperitoneal hematomas, Which was successfully treated by performing a bedside emergency surgical decompression with open linea alba fasciotomy with intact peritoneum. When patients do not respond to medical therapy, a decompressive laparotomy is the last surgical resort. In patients with severe abdominal compartment syndrome, the use of a linea alba fasciotomy is an effective intervention to lower intra-abdominal hypertension (IAH) without the morbidity of a laparotomy. Use of a linea alba fasciotomy as a first-line intervention before committing to full abdominal decompression in patients with abdominal compartment syndrome improves physiological variables without mortality. Consideration for a linea alba fasciotomy as a bridge before full abdominal decompression needs further evaluation in patients with polytrauma abdominal compartment syndrome.

PURPOSE: To evaluate and compare the radiologic and clinical follow-up of complications between a group in whom stone removal after percutaneous biliary extraction had been complete, and a group in whom this had been incomplete. MATERIALS AND METHODS: Twenty-two patients in whom stone removal had been incomplete, and 20 from whom stones had been completely removed were evaluated with particular attention to complications such as cholangitis, liver abscess, biliary sepsis, and pain. Cholangitis was diagnosed on the basis of typical clinical symptoms such as pain, high fever, jaundice and leukocytosis. Pain without other cholangitic symptoms was excluded. Liver abscess was diagnosed by percutaneous aspiration of pus, and biliary sepsis by bacterial growth on blood culture, or laboratory findings such as increased fibrinogen products, decreased fibrinogen and increased prothrombin time with cholangitic symptoms. 'Complete removal' means no residual stones on follow-up sonogram and cholangiogram performed within three to seven days after pecutaneous biliary extraction. Mean follow-up period was 26.5 months in the incomplete removal group and 34.2 months in the complete removal group. RESULTS: In twelve of 22 patients (54.5%) in the incomplete removal group, complication occurred, as follows : cholangitis, ten cases (45.5%); liver absces, one (4.5%); biliary sepsis, one (4.5%): and pain, seven (31.8%). In contrast, only two of twenty patients (10%) in the complete removal group suffered complications, all of which involved the recurrence of stones in the common duct, and choangitis. CONCLUSION: Complete removal of intrahepatic stones significantly helps to reduce the indidence of possible complications. Even in the case of an impacted stone, aggressive interventional procedures, aimed at complete removal, should be considered. If nonsurgical procedures fail, early partial hepatectomy should be considered, particulary for the stones localized in the left intrahepatic duct.

PURPOSE: The purpose of this study was to develop a nutrition quotient for adolescents (NQ-A) to assess overall dietary quality and food behavior of Korean adolescents. METHODS: Development of the NQ-A was undertaken in three steps: item generation, item reduction, and validation. Candidate items of the NQ-A checklist were selected based on literature reviews, results of the fifth Korea National Health and Nutrition Examination Survey data, dietary guidelines for Korean adolescents, expert in-depth interviews, and national nutrition policies and recommendations. A total of 213 middle and high school students participated in a one-day dietary record survey and responded to 41 items in the food behavior checklist. Pearson's correlation coefficients between the responses to the checklist items along with nutritional status of the adolescents were calculated. Item reduction was performed, and 24 items were selected for the nation-wide survey. A total of 1,547 adolescents from 17 cities completed the checklist questionnaire. Exploratory factor and confirmatory factor analyses were performed to develop a final NQ-A model. RESULTS: Nineteen items were finalized as the checklist items for the NQ-A. Checklist items were composed of five factors (balance, diversity, moderation, environment, and practice). The five-factor structure accounted for 47.2% of the total variance. Standardized path coefficients were used as weights of the items. The NQ-A and five-factor scores were calculated based on the obtained weights of the questionnaire items. CONCLUSION: Nutrition Quotient for adolescents (NQ-A) would be a useful instrument for evaluating dietary quality and food behavior of Korean adolescents. Further research on NQ-A is needed to reflect changes in adolescent's food behavior and environment.

A pyometra is an accumulation of pus in the endometrial cavity mostly due to obstruction of the cervical canal. It is a rare condition, and usually affects postmenopausal women. Moreover, spontaneous rupture of the uterus is an extremely rare complication of pyometra. We present a case of spontaneous perforation of pyometra, which presented as an acute abdomen in emergency and was misdiagnosed as gastrointestinal tract perforation.
