PURPOSE: Splenectomy, pancreas-preserving splenectomy, pancreato-splenectomy are common combined operations of a total gastrectomy for gastric cancer. We attempted to determine the efficacy of these procedures after comparing and analyzing the complication rate and the five-year survival rate from the gastric cancer patients. METHODS: 121 advanced gastric cancer patients, except T4 patients, underwent radical total gastrectomy accompanied with splenectomy. and analyzed the clinical findings eg. age, sex, location of tumor, histological differentiation, lymph node metastasis, number of dissected LN, complication and the 5-year survival rate. RESULTS: 44 out of 121 patients underwent a pancreato- splencetomy, 53 patients underwent a pancreas-preserving splenectomy, and 24 patients underwent a simple splenectomy. There were no statistical difference in the patient's age, sex, location of tumor, histological differentiation, lymph node metastasis, the number of dissected LN and the 5 year-survival rate in stage II, IV with each operation. However, a pancreas-preserving splenectomy showed a better 5-year survival rate (53.7%) than a simple splenectomy (25.0%) and pancreato-splenectomy (32.1%) in stage III. The complication rate was 25% in a simple splenectomy, 17% in a pancreas-preserving splenectomy, 30% in a pancreato- splenectomy. Diabetes mellitus occurred in 3 patients who underwent a pancreato-splenectomy, in 1 patient with an iatrogenic splenic vein excision during a pancreas-preserving splenectomy. CONCLUSION: A pancreas-preserving splenectomy is the best choice in stage IIIa total gastrectomy patients with the lowest complication rate.

Purpose: To evaluate the two-year longitudinal changes in subfoveal choroidal thickness (CT) following sulodexide treatment in patients with diabetic retinopathy. Methods: Thirty-eight eyes from patients with diabetic retinopathy, followed for a minimum of two years after sulodexide administration, were included. Subfoveal CT, measured using optical coherence tomography, was analyzed prospectively. Variables including age, sex, duration of diabetes mellitus, HbA1c, blood pressure, sulodexide treatment duration, refractive error, axial length, central macular thickness (CMT), visual acuity, laser photocoagulation, and intravitreal anti-vascular endothelial growth factor injections were evaluated for potential effects on CT. CMT, subfoveal CT, and choroidal vascularity index were compared at baseline and at 6, 12, and 24 months after sulodexide. Results: Of the 38 eyes, 10 belonged to males and 28 to females. The mean data were as follows: age, 67.18 ± 8.87 years; duration of diabetes, 18.11 ± 7.57 years; HbA1c, 8.76 ± 1.60 mmol/L; systolic blood pressure, 134.69 ± 14.68 mmHg; diastolic blood pressure, 73.72 ± 11.90 mmHg; duration of sulodexide, 25.79 ± 3.17 months; refractive error, 0.22 ± 2.19 diopters (D); and axial length, 23.32 ± 0.89 mm. During the observation period, 15 eyes underwent laser photocoagulation and 17 eyes received intravitreal anti-vascular endothelial growth factor injections. The mean subfoveal CT was 216.00 ± 64.23 μm before sulodexide administration and increased to 223.87 ± 62.18 μm, 225.53 ± 62.02 μm, and 225.76 ± 63.62 μm at 6, 12, and 24 months, respectively (p = 0.0377, p = 0.0159, p = 0.0135). The CMT was 318.14 ± 102.28 μm initially and changed to 313.08 ± 77.47 μm, 314.97 ± 88.32 μm, and 320.03 ± 97.36 μm at the aforementioned intervals, with no significant variation (p = 0.904, p = 0.736, p = 0.892). Conclusions Sulodexide administration led to a significant rise in subfoveal CT over a 2-year follow-up. This change in CT was not mirrored in the CMT.

PURPOSE: We examined the prevalence and CGG/AGG repeat structure of expanded alleles of the FMR1 gene in preconceptional and pregnant Korean women. MATERIALS AND METHODS: The CGG repeats in the FMR1 genes of 1,408 women were analyzed by polymerase chain reaction and Southern blot analysis. To estimate the prevalence of expansion alleles, the individuals were divided into low risk and high risk group. RESULTS: Within this population, 98.4% had normal alleles and 1.6% had abnormal alleles including intermediate (0.6%), premutation (0.5%), full mutation (0.1%), and hemizygous (0.4%) alleles. There were 2 premutation alleles (1:666, 95% confidence interval [CI] 1:250-1,776) in the low risk group and 5 premutation alleles (1:15, 95% 1:6-36) in the high risk group. There were 8 intermediate alleles (1:167, 95% CI 1:130-213) in the low risk group and 1 intermediate alleles (1:76, 95% CI 1:11-533) in the high group. Six of the 7 premutation alleles did not contain AGG interruptions within the repeats and 1 had a single AGG interruption. Four of the 9 intermediate alleles contained 2-3 AGG, 4 had a single AGG, and 1 had no AGG interruptions. CONCLUSION: Our study demonstrates the prevalence and CGG/AGG structure of expansion alleles in Korean women. The identified premutation prevalence is higher than that of other Asian populations and lower than that of Caucasian populations. Although our study is limited by size and population bias, our findings could prove useful for genetic counseling of preconceptional or pregnant women.

PURPOSE: We assessed the dynamic characteristics of 16 nebulizer/compressor combinations currently available in Korea. METHODS: The 16 nebulizer/compressor combinations(Pariboy Type 38/Long life, Pariboy Type N/ Long life, Pariboy Type N/Salter 8900, Pariboy Type N/LC, Devilbiss pulmoaid-LT/Hudson, Devilbiss pulmoaid/Hudson, Mesmed neb-300/Own, San-up 3040/Hudson, Midas(Basic)/Own, AirJolie 2/ Hudson, Thomas 1127/Salter 8900, Noel NE-2000/Salter 8900, Omron CX3/Hudson, Chang Woo CWN-100/Salter 8900, Voyage/Mefar, Chang Woo ASI-Pro/Medel jet pulse) were evaluated in terms of particle size and mass output. In addition, we determined the effects of nebulizer fill volume on mass output. RESULTS: Pariboy Type N/Long life has the highest respirable mass of 0.184 mg/min and Mesmed Neb-300/Own has the lowest 0.019 mg/min. Pariboy Type N/Long life has the highest mass output of 0.68 mg/min and the shortest mass median aerodynamic diameter(MMAD) of 3.76 m. All combinations other than Pariboy Type N/Long life produced a MMAD of over 5 m. MMAD over a 5 min nebulization ranged 3.76 to 9.83 m. There were no significant effects of fill volume on mass output. CONCLUSIONS: We concluded that there is a wide variation in performance of nebulizer/compressor combinations. The characteristics of nebulizer/compressor combinations should be considered in selecting products.

A 24-year-old female with primary amenorrhea was referred for a chromosome study. The karyotype of the patient was 46,X,der(X) under initial GTG-banding analysis. Fluorescence in situ hybridization (FISH) analysis with an LSI Kallmann (KAL) region probe [probes for Xp22.3(KAL) and CEP(X) for control] was carried out. The abnormal chromosome was KAL- and CEP(X)x2. In addition, interphase FISH analysis revealed the patient to be mosaic for two different cell lines: 90% of cells had three signals and 10% of the cells had only one signal for CEP(X). Based on these results, the karyotype of the patient was 45,X/46,X,psu idic(X)(p22.1), which is partial trisomy for Xqter-->Xp22.1 and partial monosomy for Xpter-->Xp22.1. This karyotype was considered a variant of Turner syndrome. In summary, Idic(X) and low-level mosaicism was successfully characterized by FISH analysis with a CEP(X) probe.

Colonic phytobezoars are defined as conglomerate masses of fruit or vegetable matter in the colon, and these have rarely reported as a cause of colon obstruction. Because it is extremely rare, its correct diagnosis might be delayed even with the aid of abdominal computed tomography. We report here on a case of diagnosed colonic obstruction due to colonic phytobezoars in a 67-year-old female with diabetic end stage renal disease and chronic constipation. Although abdomino-pelvic computed tomography did not demonstrate the presence of phytobezoars, multiple phytobezoars impacted in the colon were found and these were removed by colonoscopy. This is a rare case in that colonic obstruction due to phytobezoar was diagnosed early and it was treated by colonoscopy.

Colonic pseudo-obstruction, which is characterized by repetitive episodes or continuous symptoms and signs of a bowel obstruction, is a rare disease that results in colorectal dilatation without any obstructing lesions. Cases with neuropathic chronic colonic pseudo-obstruction have rarely been reported in Korea. We report a case of neuropathic colonic pseudo-obstruction, which results in decreased number of interstitial cells of Cajal and hypoganglionosis, in a 50-year-old man with chronic constipation accompanied by megacolon.

We have reported that a 24 kDa protein (22U homologous; As22U) of Anisakis simplex larvae could elicit several Th2-related chemokine gene expressions in the intestinal epithelial cell line which means that As22U may play a role as an allergen. In order to determine the contribution of As22U to allergic reactions, we treated mice with 6 times intra-nasal application of recombinant As22U (rAs22U). In the group challenged with rAs22U and ovalbumin (OVA), the number of eosinophils in the bronchial alveolar lavage fluid (BALF) was significantly increased, as compared to the group receiving only OVA. In addition, mice treated with rAs22U and OVA showed significantly increased airway hyperresponsiveness. Thus, severe inflammation around the airway and immune cell recruitment was observed in mice treated with rAs22U plus OVA. The levels of IL-4, IL-5, and IL-13 cytokines in the BALF increased significantly after treatment with rAs22U and OVA. Similarly, the levels of anti-OVA specific IgE and IgG1 increased in mice treated with rAs22U and OVA, compared to those treated only with OVA. The Gro-alpha (CXCL1) gene expression in mouse lung epithelial cells increased instantly after treatment with rAs22U, and allergy-specific chemokines eotaxin (CCL11) and thymus-and-activation-regulated-chemokine (CCL17) gene expressions significantly increased at 6 hr after treatment. In conclusion, rAs22U may induce airway allergic inflammation, as the result of enhanced Th2 and Th17 responses.

A serrated adenoma is a precursor lesion for some cases of microsatellite unstable colorectal carcinoma (CRC). The serrated neoplasia pathway has been associated with carcinogenesis of serrated adenoma, which is different from the traditional adenoma-carcinoma sequence. The serrated neoplasia pathway accounts for 10~15% of CRCs, and these tumors typically demonstrate microsatellite instability. Cases of a CRC arising from a serrated adenoma have been rarely identified with the recent recognition of the serrated neoplasia pathway. However, these cases are not frequently reported in Korea, because this concept has only been recently emphasized. We report a case of an early adenocarcinoma arising from a traditional serrated adenoma of the colon, which was diagnosed and treated by a colonoscopic polypectomy.

OBJECTIVE: To investigate whether higher resilience level predicts low levels of psychological distress in chronic SCI patients living in the community. METHOD: Thirty seven patients (mean age 41.5+/-10.9, male : female=28 : 9) with chronic spinal cord injury (duration 8.35+/-7.0 years) living in the community are included, who were hospitalized for annual checkups from November, 2010 to May, 2011. First, their spinal cord injury level, completeness and complications were evaluated. The patients completed questionnaires about their educational status, religion, employment status, marital status, medical and psychological history and also the following questionnaires: Hospital Anxiety and Depression Scale (HADS), Connor-Davidson Resilience Scale (CD-RISC), Alcohol Use Disorders Identification Test-alcohol consumption questions (AUDIT-C) and Health-related quality of life (EQ-5D). The patients were divided into two subgroups: patients with HADS > or =13 are classified as high psychological distress group and others as low psychological distress group. We compared the two groups to find statistically significant differences among the variables. RESULTS: CD-RISC, EQ-5D and employment status are significantly different between two groups (p<0.05). In a forward stepwise regression, we found that EQ-5D had a greater contribution than CD-RISC to the psychological distress level. CONCLUSION: In addition to health-related quality of life, resilience can be suggested as a possible predictor of psychological distress in chronic SCI patients.
