OBJECTIVES: There have been no consistent reliable and valid tool for examining the psychosocial problems for the patients with mental disorders in Korea. The purpose of the present study is to develop a scale that examine the psychosocial problems for the patients with mental disorders and to test its reliability and validity. METHODS: To identify the psychosocial problems for 1,100 patients with mental disorders were selected in university hospitals and professional training institutes. And the items of the psychosocial problems were taken from them and divided them into individual and environmental categories. The representative items were established among these items of psychosocial problems and a questionnaire for a pilot study was made based on the representative items. The pilot study was done for 306 patients with mental disorders using the questionnaire to investigate reliability of the questionnaire. After the pilot study items and format of the questionnaire were revised and complemented. The revised questionnaire was given to 600 patients with mental disorders to test its validity and reliability and new scale for psychosocial problems was developed. RESULTS: At the pilot study, which was performed with 1,100 patients, 3,200 items of psychosocial problems of 205 types were selected. Among these items 78 representative psychosocial problems items were withdrawn. Fifty-eight psychosocial problem items were finally set for the questionnaire after discussing them with the expert groups and examining its content reliability. Forty-seven psychosocial problems items were finally selected and given to 306 subjects at the pilot study. At the main study in which 600 subjects were tested inner-reliability. Correlation between items and scale was relevant and correlation coefficient between test and retest was high. The finally developed psychosocial problems testing scales were consisted of 46 testing items into 9 areas. CONCLUSION: The Psychosocial Problems Assessment Scale, which were developed at this study is proved to be valid and reliable and it will be able to be used to examine overall psychosocial problems for the patients with mental disorders in Korea.

Langerhans cell histiocytosis (LCH) is a rare disease of the monocyte-macrophage system involving clonal proliferation of Langerhans cells. Central nervous system (CNS) involvement of LCH occurs in 10-57% of all LCH cases. This disease is known to present in two ways in the CNS: intracranial tumorous lesions or intracranial nontumorous lesions (neurodegeneration). We report here an LCH patient who developed gait disturbance and dysarthria due to neurodegenerative lesions associated with LCH.

Cerebral venous sinus thrombosis is a rare type of cerebrovascular disease with highly variable clinical features. Although intracranial hemorrhage can occur in a patient with cerebral venous sinus thrombosis, the development of subdural hemorrhage has been infrequently reported. Herein we report a 49-year-old woman with cerebral venous sinus thrombosis who developed subdural hemorrhage. We presumed that the elevation of venous or capillary pressure caused by venous sinus thrombosis played an important role in the development of subdural hemorrhage.

PURPOSE: We evaluated the efficacy of breast magnetic resonance imaging (MRI) for detecting additional malignancies in breast cancer patients newly diagnosed by breast ultrasonography and mammography. METHODS: We retrospectively reviewed the records of 1,038 breast cancer patients who underwent preoperative mammography, bilateral breast ultrasonography, and subsequent breast MRI between August 2007 and December 2010 at single institution in Korea. MRI-detected additional lesions were defined as those lesions detected by breast MRI that were previously undetected by mammography and ultrasonography and which would otherwise have not been identified. RESULTS: Among the 1,038 cases, 228 additional lesions (22.0%) and 30 additional malignancies (2.9%) were detected by breast MRI. Of these 228 lesions, 109 were suspected to be malignant (Breast Imaging-Reporting and Data System category 4 or 5) on breast MRI and second-look ultrasonography and 30 were pathologically confirmed to be malignant (13.2%). Of these 30 lesions, 21 were ipsilateral to the main lesion and nine were contralateral. Fourteen lesions were in situ carcinomas and 16 were invasive carcinomas. The positive predictive value of breast MRI was 27.5% (30/109). No clinicopathological factors were significantly associated with additional malignant foci. CONCLUSION: Breast MRI was useful in detecting additional malignancy in a small number of patients who underwent ultrasonography and mammography.

The nephrotic syndrome that occurs in the absence of renal vein thrombosis, amyloidosis, neoplastic infiltration of the kidneys is an unusual but a well recognized paraneoplastic syndrome. The most frequently reported neoplasms associated with nephrotic syndrome are Hodgkin's disease and various carcinomas. The most common renal lesions are membranous glomerulonephritis(MGN) associated with carcinomas and minimal change lesions associated with Hodgkin's disease. Approximately 40% to 45% of patients clinically manifest the MGN symptoms prior to the diagnosis of the tumor, 40% simultaneously with the tumor and the remaining 15% to 20% following the tumor. Therefore, evaluating the underlying malignancy in patients with MGN is important. Here we report a patient with squamous cell lung cancer, which was detected 12 months after a MGN had been diagnosed, with a review of the relevant literature.

Background/Aims:
Immunocompromised patients with acute colonic diverticulitis are at high risk for complications and failure of non-surgical treatment. However, evidence on the comparative outcomes of immunocompromised and immunocompetent patients with diverticulitis is lacking. This systematic review and meta-analysis investigated the outcomes of medical treatment in immunocompromised and immunocompetent patients with diverticulitis.
Methods:
A comprehensive literature search was conducted in PubMed, Embase, and the Cochrane Library. Studies comparing the clinical outcomes of immunocompromised and immunocompetent patients with diverticulitis were included.
Results:
A total of 10 studies with 1,946,461 subjects were included in the quantitative synthesis. The risk of emergency surgery and postoperative mortality after emergency surgery was significantly higher in immunocompromised patients than in immunocompetent patients with diverticulitis (risk ratio [RR], 1.76; 95% confidence interval [CI], 1.31–2.38 and RR, 3.05; 95% CI, 1.70–5.45, respectively). Overall risk of complications associated with diverticulitis was non-significantly higher in immunocompromised than in immunocompetent patients (RR, 1.24; 95% CI, 0.95–1.63). Overall mortality irrespective of surgery was significantly higher in immunocompromised than in immunocompetent patients with diverticulitis (RR, 3.65; 95% CI, 1.73–7.69). By contrast, postoperative mortality after elective surgery was not significantly different between immunocompromised and immunocompetent patients with diverticulitis. In subgroup analysis, the risk of emergency surgery and recurrence was significantly higher in immunocompromised patients with complicated diverticulitis, whereas no significant difference was shown in mild disease.
Conclusions
Immunocompromised patients with diverticulitis should be given the best medical treatment with multidisciplinary approach because they had increased risks of surgery, postoperative morbidity, and mortality than immunocompetent patients.

Background/Aims:
Some management strategies for acute colonic diverticulitis remain controversial in Korean real-world practice because their clinical features differ from those in the West. This study aimed to investigate the opinions of Korean physicians regarding the diagnosis and treatment of acute diverticulitis.
Methods:
A web-based survey was conducted among gastroenterologists specializing on treating lower gastrointestinal disorders. The questionnaires concerned overall management strategies for colonic diverticulitis, including diagnosis, treatment, and follow-up.
Results:
In total, 209 gastroenterologists responded to the survey. Less than one-fourth of the respondents (23.6%) answered that left-sided colonic diverticulitis is more likely to be complicated than right-sided colonic diverticulitis. Most respondents agreed that immunocompromised patients with diverticulitis have worse clinical outcomes than immunocompetent patients (71.3%). Computed tomography was the most preferred tool for diagnosing diverticulitis (93.9%). Approximately 89% of the respondents answered that they believed antibiotic treatment is necessary to treat acute uncomplicated diverticulitis. Most respondents (92.6%) agreed that emergency surgery is not required for diverticulitis with an abscess or microperforation without panperitonitis. Further, 94.7% of the respondents agreed that colon cancer screening is necessary in patients aged ≥ 50 years with diverticulitis after they have recovered from acute illness. Many respondents (71.4%) agreed that surgery for recurrent diverticulitis should be individualized.
Conclusions
Opinions regarding management strategies for colonic diverticulitis among Korean gastroenterologists were well agreed upon in some areas but did not agree well in other areas. Evidence-based guidelines that meet the practical needs of the Korean population should be developed.

PURPOSE: The need for surgical excision in patients with ultrasound-guided core needle biopsy (CNB)-diagnosed atypical ductal hyperplasia (ADH) remains an issue of debate. The present study sought to validate a scoring system (the U score, for underestimation) that we have previously developed for predicting malignancy in CNB-diagnosed ADH. METHODS: The study prospectively enrolled 85 female patients with CNB-diagnosed ADH who underwent subsequent surgical excision. Underestimation was defined as a surgical specimen having malignant foci. RESULTS: The overall underestimation rate was 37% (31/85). Multivariate analysis showed that a clinically palpable mass, microcalcification on imaging, size >15 mm and a patient age of > or =50 years were independently associated with underestimation. When applied to the scoring system, the validation score was significant (p<0.001; area under the curve, 0.852). No patient with a U score <3.5 had an underestimated lesion. CONCLUSION: The present study successfully validated the efficacy of our scoring system for predicting malignancy in CNB-diagnosed ADH. A U score of < or =3.5 indicates that surgical excision may not be necessary.

OBJECTIVE: To determine whether polymorphisms of the Vitamin D receptor (VDR)gene,known to be associated with osteoporosis and/or osteoarthritis (OA) in Caucasians,might also relate to the risk of OA and osteoporosis in Korean postmenopausal women METHODS: A population of 130 postmenopausal women,including 76 healthy controls and 54 knee OA patients,were studied using anteroposterior radiographs of the knee,which were graded for OA according to the Kellgren classification system.The VDR genotype was determined by using polymerase chain reaction and by digestion with the three restriction enzymes Taq I,Bsm I,and Apa I.Femoral neck bone mineral density (BMD)was assessed in all participants by dual energy X-ray absorptiometry . RESULTS: VDR genotype frequency distributions in Koreans were much different from Caucasian's both in the OA group and the control group.Especially, "t t", "B B" and "A A" genotype were very rare,prominently differentiating from Caucasians.But within Koreans,no significant differences in VDR genotype frequencies were observed between OA cases and controls.VDR genotype was not significantly associated with the radiographic grades of OA.And there were no significant relationships of VDR genotype with BMD scores in each group. CONCLUSION: In Korean postmenoposal women,the VDR gene polymorphisms do not significantly contribute to an increased prevalence of knee OA or to differences in BMD.VDR genotype analysis would not be helpful for assessing the risk of knee OA in Koreans because :(1)there is no correlation of VDR genotypes with the radiographic severity of OA ;and (2)there is a more skewed distribution of VDR genotypes in Korean population compared to the Caucasian's .

Purpose:
Agonists of the stimulator of interferon genes (STING) play a key role in activating the STING pathway by promoting the production of cytokines. In this study, we investigated the antitumor effects and activation of the systemic immune response of treatment with DMXAA (5,6-dimethylxanthenone-4-acetic acid), a STING agonist, in EML4-ALK lung cancer and CT26 colon cancer.
Materials and Methods:
The abscopal effects of DMXAA in the treatment of metastatic skin nodules were assessed. EML4-ALK lung cancer and CT26 colon cancer models were used to evaluate these effects after DMXAA treatment. To evaluate the expression of macrophages and T cells, we sacrificed the tumor-bearing mice after DMXAA treatment and obtained the formalin-fixed paraffin-embedded (FFPE) tissue and tumor cells. Immunohistochemistry and flow cytometry were performed to analyze the expression of each FFPE and tumor cell.
Results:
We observed that highly infiltrating immune cells downstream of the STING pathway had increased levels of chemokines after DMXAA treatment. In addition, the levels of CD80 and CD86 in antigen-presenting cells were significantly increased after STING activation. Furthermore, innate immune activation altered the systemic T cell-mediated immune responses, induced proliferation of macrophages, inhibited tumor growth, and increased numbers of cytotoxic memory T cells. Tumor-specific lymphocytes also increased in number after treatment with DMXAA.
Conclusion
The abscopal effect of DMXAA treatment on the skin strongly reduced the spread of EML4-ALK lung cancer and CT26 colon cancer through the STING pathway and induced the presentation of antigens.
