Objective : The aim of this study was to evaluate cross - reactivity between pollens in patients with strong skin reactivity to multiple pollens. METHODS: A pool of sera from 20 patients who showed strong skin responses( > or = 3+ ) to all three kinds of pollens ( tree, grass, and weed ) was used. Oak, ryegrass, mugwort, ragweed and hop Japanese pollens were chosen for the subject of study. The level and pattern of bound IgE to each pollen and cross - reactivity between pollens were investigated by ELISA and immunoblot experiments. RESULTS: In ELISA, the IgE of a pool of sera reacted to ryegrass and ragweed in 100%, to mugwort in 95%, to oak in 75%, and to hop Japanese in 65%, respectively. In inhibitory ELI - SA, more than 50% of bound IgE was mutually inhibited in oak vs ryegrass, oak vs mugwort, mugwort vs ryegrass and mugwort vs hop Japanese. In immunoblot, the IgE binding rate to major allergens of each pollen was 95% for hop Japanese, 75% for ragweed, 50% for ryegrass, 35% for mugwort, and 30% for oak, respectively. In inhibitory immunoblot, the mutually inhibited bound IgE could not be observed between major allergens of each pollen, but some minor allergens of oak pollen were mutually inhibited by ryegrass. CONCLUSION: Cross - reactivity between major allergens of oak, ryegrass, mugwort, ragweed and hop Japanese pollens was not observed at all, but some minor allergens of oak pollen cross-reacted with ryegrass and mugwort, and so did those of mugwort pollen with ryegrass and hop Japanese.

PURPOSE: A 25% rate of recurrence after performing complete resection in node-negative colon cancer patients suggests that their nodal staging is frequently suboptimal. Moreover, the value of occult cancer cells in tumor-free lymph nodes still remains uncertain. The authors evaluated the prognostic significance of the pathologic parameters, including the lymph node occult disease (micrometastases) detected by immunohistochemistry, in patients with node-negative colon cancer. MATERIALS AND METHODS: The study included 160 patients with curatively resected stage I or II colon cancer and they were without rectal cancer. 2852 lymph nodes were re-examined by re-do hematoxylin and eosin (H-E) staining and immunohistochemical staining. The detection rates were compared with the clinicopathologic characteristics and with the cancer-specific survival. RESULTS: Occult metastases were detected in 8 patients (5%). However, no clinicopathologic parameter was found to be correlated with the presence of micrometastasis. Twenty patients developed recurrence at a median follow-up of 45.7 months: 14 died of colon cancer and 9 died from noncancer-related causes. Univariate analysis showed that lymphatic invasion and the number of retrieved lymph nodes significantly influenced survival, and multivariate analysis revealed that the stage, the number of retrieved lymph nodes and lymphatic invasion were independently related to the prognosis. CONCLUSIONS: Inadequate lymph node retrieval and lymphatic invasion were found to be associated with a poorer outcome for node-negative colon cancer patients. The presence of immunostained tumors cells in pN0 lymph nodes was found to have no significant effect on survival, but these tumor were identified by re-do H-E staining. Maximal attention should be paid to the total number of lymph nodes that are retrieved during surgery for colon cancer patients.

BACKGROUND: Although good clinical effects have been reported, immunotherapy with house dust mite ( HDM ) antigen - autologous specific antibody complex ( IC - IT ) is not yet accepted as an effective immunomodulating tool in HDM allergic diseases. We aimed to prove the clinical effect of IC - IT in HDM sensitized respiratory allergic subjects. Method : Six HDM sensitized respiratory allergic subjects were enrolled. Autologous D. farinae specific IgG was purified with DEAE ion exchange and affinity chromatography. After one year of IC - IT treatment the clinical effects were analyzed with symptom scores, methacholine PC20, ELISA assay of D. farinae specific antibodies and intradermal skin reactivity. Result : The rhinitis symptom score significantly improved after a one - year administration of IC - IT ( 1.23 +/- 0.30 vs. 0.37 +/- 0.15, p< 0.05), but no significant differences were found in asthma symptom score, intradermal skin reactivity to D. farinae and ELISA optic absorbances of D. farinae specific IgE, IgG, and IgG subclasses. Methacholine PC20 values improved in all 6 patients who were administered with IC - IT ( 0.35 vs. 1.66 mg/ml, p< 0.05 ). CONCLUSION: IC - IT may be efficient for management of HDM atopic asthma. Further studies are needed before clinical application of IC - IT in house dust mite atopic subjects.

Interchromosomal insertion of Y chromosome heterochromatin in an autosome was identified in a fetus and a family. A fetal karyotype was analyzed as 46,XX,dup(7)(?q22q21.1) in a referred amniocentesis at 16 weeks of gestation for advanced maternal age. In the familial karyotype analyses for identification of der(7), the mother, the first daughter and the maternal grandmother showed the same der(7) as the fetus's. CBG-banding was positive at 7q22 region of der(7) that indicated inserted material was originated from heterochromatin. The origin of heterochromatic insertion region in der(7) of the fetus and the mother was found in Yq12 region by fluorescent in situ hybridization with a DYZ1 probe. In the specific analysis of Y chromosomal heterochromatic region of ins(7;Y) of the mother, 15 sequence tagged sites from Yp11.3 region including SRY to Yq11.223 region was not detected. Final karyotypes of the mother, the first daughter and the maternal grandmother were reported as 46,XX,der(7)ins(7;Y)(q21.3;q12q12). All female carriers of ins(7;Y) in the family showed normal phenotype and the mother and the maternal grandmother were fertile. A healthy girl was born at term. We report a rare case of familial interchromosomal insertion of Y chromosome heterochromatin detected only in female family members with normal phenotype that was diagnosed prenatally.

PURPOSE: The aims of this study were to develop and test the validity of the Korean Nursing Delirium Scale (Nu-DESC) for older patients in hospital. METHODS: The Korean Nu-DESC was developed based on the Nu-DESC (Gaudreau, 2005), and revised according to nursing records related to signs and symptoms of older patients with delirium (n=361) and the results of a pilot study (n=42) in one general hospital. To test the validity of the Korean Nu-DESC, 75 older patients whom nurses suspected of delirium from 731 older patients from 12 nursing units were assessed by bedside nurses using the Korean Nu-DESC. A Receiver Operating Characteristic Curve of the Korean Nu-DESC was constructed with an accompanying Area Under the Curve (AUC). RESULTS: Specific examples such as irritable, kidding, sleeping tendency, which were observed by bedside nurses in Korea, were identified in the five features of signs and symptoms of delirium in the instrument. The Korean Nu-DESC was psycho-metrically valid and had a sensitivity and specificity of .81-.76 and .97-.73, respectively. The AUC were .89, .74. CONCLUSION: Results of this study indicate that the Korean Nu-DESC is well-suited for widespread clinical use in busy inpatients settings and shows promise as a research instrument.

OBJECTIVE: This study investigated the effects of additional balance training using three dimensional balance trainer on dynamic balance, gait symmetry and fall efficacy in subacute hemiplegic stroke patients. METHOD: This study designed pretest-posttest control group. Twenty subacute stroke patients were randomly assigned to an experimental or a control group. All patients had conventional physical therapy. In addition, 10 patients in experimental group was trained with the three dimensional balance trainer (BalPro(R)) for 30 min/day, 5 day/week for 4 weeks. All participants were assessed by: Berg Balance Scale (BBS), Timed Up and Go test (TUG), gait symmetry, and Fall efficacy scale-Korea (FES-K) before and after training. RESULTS: All participants of both group showed statistically significant improvements in dynamic balance, gait symmetry and fall efficacy. More improvements were shown significantly in experimental group than those in control group in BBS, TUG, step length symmetry (p<0.05) and single limb support symmetry (p<0.01). CONCLUSION: Additional balance training with conventional physical therapy is feasible and may be an effective tool to improve dynamic balance and gait symmetry in subacute patients.

The purpose of this article was to evaluate the accuracy of predicting amnionicity using the number of yolk sacs by diagnostic ultrasound examination in monochorionic (MC) multifetal pregnancies between 7 + 0 and 9 + 6 gestational weeks. A total of 97 patients with MC multifetal pregnancies underwent early ultrasound examination from 2004 to 2014 at Cheil General Hospital and Women's Healthcare Center. All patients for whom the number of yolk sacs was reported were included in this study. We compared the number of yolk sacs with amnionicity confirmed by an intertwine membrane. Overall, there was a 9.3% (9 cases) discrepancy in number of yolk sacs and amnionicity (4.3% for monochorionic diamniotic, 36.4% for monochorionic monoamniotic, and 33% for monochorionic triamniotic). Among the 9 cases with discrepancies, 4 cases with 2 yolk sacs were confirmed as monoamniotic pregnancies and 4 MC twin pregnancies showing a single yolk sac were diagnosed as diamniotic twin pregnancies. One case with 2 yolk sacs was identified as a triamniotic triplet pregnancy. In 9.3% of MC gestations, the number of yolk sacs was not correlated with the number of amnions in our study. To determine amnionicity in MC multifetal pregnancies, we recommend careful evaluation not of the number of yolk sacs but the presence or absence of intertwine dividing membrane after 8 gestational weeks.

PURPOSE: Depression is common in patients with chronic renal failure on maintenance hemodialysis, though success rate of treatment is low. This study aimed to investigate the features and severity of the depressive symptoms and nutritional indices, and significant changes after antidepressant treatment. METHODS: The authors assessed 45 patients. Diagnosis of depression was made using DSM-IV-TR and the depressive symptoms were evaluated using Hamilton Rating Scale for Depression via semi- structured interview. Subjective global assessment, anthropometric measurements and nutritional indices such as Kt/V, nPCR were examined. Depressive patients were treated for 8 weeks with SSRI (citalopram), and all the variables were examined again after the treatment. RESULTS: 19 (42.2%) patients were diagnosed as depression. Nutritional status was not different between patients with depression and those without depression. Compared to non-depressed patients, depressed patients showed significantly higher depressed mood, guilty feeling, suicide idea, psychic and somatic anxiety, lower work and activities, psychomotor retardation, sleep disturbances, general somatic symptoms and hypochondriasis. After antidepressant treatment, depressed mood, guilty feeling, suicide idea, psychic anxiety, initial insomnia, middle insomnia, early awakening, work and activities and general somatic symptoms were improved significantly. TSF (p<0.05), handgrip strength (p<0.01) and hematocrit (p<0.05) were significantly increased. CONCLUSION: Antidepressant treatment is helpful not only for the improvement of depressive symptoms such as sleep and somatic symptoms but for the improvement of quality of life. Proper treatment should be more actively attempted for the hemodialytic patients with depression.

Journal of Rhinology 2011;18(2):155-159
Cerebrospinal fluid (CSF) leakage is a possible major complication in skull base surgery. Application of the expanded endoscopic endonasal approach in skull base surgery expands the accessibility to resect skull base lesions but also increases the risk of CSF leakage due to the creation of larger dural defects in the skull base. Reconstruction of the skull base with multilayered autologous materials has been a key surgical technique. A recent advance in skull base reconstruction is nasoseptal flap, a robust reliable vascular pedicled flap supplied with the septal branch of the sphenopalatine artery. This technique has been reported to significantly decrease the risk of CSF leakage. We report a case of giant pituitary adenoma involving the suprasellar space and sphenoid sinus with a near total sellar defect. The lesion was removed using the endoscopic endonasal transsphenoidal approach, and the sellar floor was successfully reconstructed using a nasoseptal flap with no other multilayered support.
