The neurofibromatoses are a rare group of hereditary diseases of autosomal dominant fashion with the overall incidence of one in 3,000~4,000 and with two distinct forms, type I (Von Recklinghausen's neurofibromatosis) characterized by skin lesions including multiple cutaneous neurofibromas, axillary and groin freckling, and cafe-au-lait spots and type II by the presence of bilateral vestibular schwannomas. The neurofibromatosis type I is associated with the mutation of NF-I gene on chromosome 17q 11.2, which has a tumor suppressive role and with resultant development of the wide variety of tumors with the malignant incidence of about 2~16 %. Although the cases of malignant tumors in the neurofibromatosis type I have been reported in various tumors with the neural origin, lymphoma, pheochromocytoma and some cases of gastrointestinal tumors, the gastrointestinal tumors were found in only hepatobiliary system and large and small bowels and the cases of the malignant tumors of upper GI origin in duodenum and stomach have not been reported yet in Korea. We report a case of a 64-year-old man admitted with epigastric pain and diagnosed to adenocarcinoma, signet ring cell type, in 2nd portion of duodenum associated with neurofibromatosis type I.

PURPOSE: To analyze stereoacuity in patients with strabismus using various stereotests. METHODS: Stereoacuity was assessed in children who were diagnosed with intermittent exotropia or refractive accommodative esotropia using the Titmus stereotest, TNO stereotest, and the Lang II stereotest. Patients with amblyopia or previous ocular surgery were excluded. RESULTS: Ninety-four patients with intermittent exotropia and 36 patients with refractive accommodative esotropia were included; the mean age was 7.2 years. The mean stereoacuity in intermittent exotropia was 143.1+/-207.9 seconds of arc with the Titmus stereotest, 130.2+/-103.7 seconds of arc with the TNO stereotest, and 200.0+/-0.0 seconds of arc with the Lang II stereotest. The mean stereoacuity in refractive accommodative esotropia was 430.3+/-288.6 seconds of arc, 232.5+/-90.0 seconds of arc, and 230.0+/-97.9 seconds of arc, respectively. The absence of stereoacuity was more frequent in patients with refractive accommodative esotropia than in patients with intermittent exotropia, and both groups of patients showed the largest proportion of absent stereopsis with the TNO stereotest. No factor was significant for stereopsis in patients with intermittent exotropia and patients with refractive accommodative esotropia. CONCLUSIONS: Stereoacuity showed various seconds of arc according to the type of stereotest in the same patient. Patients with refractive accommodative esotropia showed lower stereoacuity in all stereotests than patients with intermittent exotropia. TNO stereotests are sensitive enough to detect the absence of stereopsis in patients with strabismus.

OBJECTIVE: We examined the association between the tryptophan hydroxylase 1 (TPH1) gene and eating disorders focusing on obsessionality. METHODS: The sample included 62 women with a lifetime diagnosis of anorexia nervosa (AN) as well as 50 women with a lifetime diagnosis of bulimia nervosa (BN) recruited from specialist clinics for eating disorders and 131 healthy women in Korea. Blood samples were collected from all participants for the TPH1 genotyping. The patients were ad ministered the Korean version of the Eating Disorders Examination and obsessionality was conceptualized using measures of persistence, harm avoidance, and obsessive-compulsive symptoms. RESULTS: In the case-control comparisons, the frequency of the A/A genotype was increased in the patients with BN, but this difference was not significant after correcting for multiple testing. We found no effect of the TPH A218C polymorphism on obsessionality in the patients with AN or BN. CONCLUSION: Although the present findings should be regarded as preliminary because of the small size of our sample, they suggest that the TPH1 gene may contribute to the genetic susceptibility to BN and be associated with the other unexplored traits of bulimic case status.

PURPOSE: Preclinical studies have shown that human epidermal growth factor receptor 2 (HER2) status is associated with resistance to radiotherapy (RT). In this study, we evaluated the overall survival of a T1N0M0 breast cancer cohort in Korea according to the use of RT and the HER2 status. METHODS: We analyzed data collected from 11,552 patients with invasive breast cancer who were enrolled in the Korean Breast Cancer Society Registration Program between 1999 and 2007. Data on the TNM stage, estrogen receptor status, progesterone receptor status, HER2 status, operation method, and the use of RT were analyzed. RESULTS: The median follow-up period was 51 months. A significant improvement in overall survival after RT was observed only in the HER2(-) group. In this group, the 10-year overall survival rate was 95.5% for patients who did not receive RT and 96.3% for patients who received RT (p=0.037). In contrast, in the HER2(+) group, RT was not associated with a survival benefit (p=0.887). Multivariate analysis showed that RT was significantly associated with a reduction in mortality in the HER2(-) group (hazard ratio, 0.738; 95% confidence interval, 0.549-0.993; p=0.045). CONCLUSION: We found that postoperative RT was not associated with a survival benefit in HER2(+) breast cancer patients, suggesting that HER2(+) breast cancers could be RT resistant.

OBJECTIVE: To compare the functional outcomes between surgical treatment and conservative medical treatment for severe middle cerebral artery (MCA) infarction. METHOD: This is comparative analysis of prospectively documented data with 25 patients have malignant MCA infarction. Ten patients in Group A (male 7, female 3) received surgical treatment such as decompressive craniectomy, and fifteen patients in Group B (male 10, female 5) received conservative medical treatment. We defined MCA infarction as "severe" when it concerned both the deep and superficial areas of the MCA or when the Functional Independence Measure (FIM) was lower to 75 on admission to our department. Functional status was measured using modified Rankin Scale (mRS), FIM, Motricity Index (MI) and Trunk Control Test (TCT). All evaluations were measured at baseline and 90 days after stroke. RESULTS: Mean age were 55.0 +/- 8.6 and 58.7 +/- 12.3 in Group A and B. Rt. MCA infarction were 4 in Group A and 5 in Group B. Lt. MCA infarction were 5 in Group A and 10 in Group B. Baseline functional status between two groups was not significantly different. Each group showed functional improvement according to the time. When compared changes between two groups, arm Motricity Index, K-MMSE, mRS and FIM were no significant difference between two groups. Leg segments of MI and TCT was significantly improved in Group A more than B at 90 days after baseline evaluation (p<0.05). CONCLUSION: Decompressive craniectomy improved motor function of affected leg and trunk in patients with severe MCA infarction more than conservative medical treatment alone.

Stable carbon and nitrogen isotope analysis reveals the diets of different human populations in history. In this study, we performed stable isotope analysis on human skeletons from Joseon-period cemeteries discovered around Old Seoul City (Hansung). Our data clearly showed that Joseon individuals consumed more C3-based than C4-based foods as the main staples, and that the proteins they ate were mainly of terrestrial, but not of marine origin. Stable isotope values exhibited unique patterns in each of our sample subgroups. Whereas the delta13C values did not show any statistical differences among the subgroups, significantly higher values of delta15N were found in males than in females, which might reflect dietary differences between the sexes. For a fuller understanding of the dietary patterns of pre-industrial (pre-20th century) Koreans, additional studies on Joseon samples from Korean archaeological sites will be necessary.

OBJECTIVES: Schizophrenic patients having a disturbance of cognition and emotion are least likely to identify emotional (especially negative) stimuli and cue in tense background stimuli. Also, schizophreinic patients tend to experience relapse if they are exposued to a situation which is emotionally laden. Although emotion itself is important, emotional processing has not been a therapeutic target and skill trainig which improves social competence has provided patients with emotional load. Therefore, we introduced Emotional Management Trainig (EMT) which deal with indirect and direct emotional processing, applied it to schizophrenic patients, and investigated the therapeutic effects. METHODS: We applied the Emotional Management Training (EMT) to 30 schizophrenic patients for 12 weeks, 2 times every week and psychoeducation to 23 schizophrenic patients as control group attention-placebo for 12 weeks, during the same period. Before and after treatment, we used the Trait Meta Mood Scale-short form (TMMS-S) as emotional proper, Social Perception Scale, Verbal Fluency Test, Verbal Paired Associates, and Similarities for cognitive functions. We also used Positive And Negative Syndrome Scale (PANSS) as psychopathology measurement and Social Problem Solving Scale (SPSI) as various kinds of social problem solving function measurement before and after treatment. RESULTS: The results showed that EMT group appeared to be more effective in improving the visual perception of social perception scale, verbal fluencies, positive symptoms, general psychopathology, and total score in PANSS than the control group. Also EMT group seemed to be more effective in total score and Problem Orientation score in SPSI than the control. But there were no differences in abstract function and verbal memory, negative symptoms, and Problem-Solving Skill score between the two groups. CONCLUSION: This study suggests that despite the limitations of the generalizability and the questions for the persistence of effectiveness, EMT might help schizophrenics get the motivational aspects, the familiarity with emotional-loaded situation, and initial processes, for social problem-solving.

OBJECTIVE: Panic disorder (PD) is frequently comorbid with insomnia, which could exacerbate panic symptoms and contribute to PD relapse. Research has suggested that characteristics are implicated in both PD and insomnia. However, there are no reports examining whether temperament and character affect insomnia in PD. Thus, we examined the relationship between insomnia and personality characteristics in PD patients. METHODS: Participants were 101 patients, recruited from 6 university hospitals in Korea, who met the DSM-IV-TR criteria for PD. We assessed sleep outcomes using the sleep items of 17-item Hamilton Depression Rating Scale (HAMD-17)(item 4=onset latency, item 5=middle awakening, and item 6=early awakening) and used the Cloninger's Temperament and Character Inventory-Revised-Short to assess personality characteristics. To examine the relationship between personality and insomnia, we used analysis of variance with age, sex, and severity of depression (total HAMD scores minus sum of the three sleep items) as the covariates. RESULTS: There were no statistical differences (p>0.1) in demographic and clinical data between patients with and without insomnia. Initial insomnia (delayed sleep onset) correlated to a high score on the temperamental dimension of novelty seeking 3 (NS3)(F1,96=6.93, p=0.03). There were no statistical differences (p>0.1) in NS3 between patients with and without middle or terminal insomnia. CONCLUSION: The present study suggests that higher NS3 is related to the development of initial insomnia in PD and that temperament and character should be considered when assessing sleep problems in PD patients.
