The FK506 binding protein 5 (FKBP5) is a co-chaperone that regulates the activity of the glucocorticoid receptor (GR) and has been reported to mediate stress resilience. This study aimed to determine the effects of Fkbp5 deletion on acute stress-induced recognition memory impairment and hippocampal GR signaling. Wild-type and Fkbp5-knockout mice were subjected to acute uncontrollable stress induced by restraint and electrical tail shock. First, we assessed the cognitive status of mice using a novel object recognition task. Next, we measured plasma corticosterone, GR levels, and the levels of GR phosphorylation at serine 211 in the hippocampus. Wild-type mice exhibited stress-induced memory impairments, whereas Fkbp5-knockout mice did not. Plasma corticosterone and GR levels did not differ between the non-stressed wild-type and Fkbp5-knockout mice, but the levels of phosphorylated GR were lower in Fkbp5-knockout mice than in wild-type mice. Wild-type and Fkbp5-knockout mice showed increased nuclear GR levels following stress, indicating GR translocation. However, cytosolic phosphorylated GR levels were lower in the hippocampi of Fkbp5-knockout mice following stress than in those of wild-type mice. These results suggest that FKBP5 deficiency increases resilience to acute stress by altering GR signaling.

PURPOSE: This is a descriptive study conducted in order to survey sleep patterns and factors responsible for sleep disturbance among adolescent cancer patients after hospital admission. METHODS: The study group included 46 adolescent cancer patients aged 10 to 19 who received admission care in multi-bed hospital rooms from March to June 2016. Data on patterns and quality of sleep, and factors causing sleep disturbance were recorded using the Verran and Snyder-Halpern (VSH) Sleep Scale, the Pittsburgh Sleep Quality Index (PSQI), and a sleep disturbance questionnaire. RESULTS: There was no difference in patterns and quality of sleep prior to and after hospital admission in the study group. However, patients experienced sleep disturbance, as defined by PSQI > 5, both before (5.43) and after (6.30) admission. The most important physical, emotional and environmental factors causing sleep disturbance after admission were nocturnal diuresis, monotony of admission care, and crying of younger patients respectively. CONCLUSION: This study focused on sleep patterns and factors causing sleep disturbance after hospital admission for adolescent cancer patients. Future studies should aim to develop nursing interventions resulting in an environment that improves sleep quality. Additional studies should focus on developing daytime programs to determine the impact of admission care on other quality of life parameters.

Interruption of the aortic arch is an uncommon congenital cardiovascular malformation invariably accompanied by other cardiovascular anomalies. This carries a 76% mortality rate in the first month of life. We recently experienced a case of interruption of the aortic arch with patent ductus arteriosus in a 21-year-old man with systolic murmur. he did not showed any other symptoms or signs. Cardiac catheterization with angiography showed interruption of the aortic arch with many systemic arterial collaterals and patent ductus arteriosus.

BACKGROUND: We examined the usefulness of urine osmolality, as a predictive factor in the treatment of monosymptomatic nocturnal enuresis (NE) with combination therapy of imipramine and desmopressin. METHODS: From May 2014 to April 2015, 59 monosymptomatic NE patients participated in this study. Early morning urine osmolality was measured at 1 week and 1 day before combination therapy of imipramine and desmopressin, and at 1 week and 2 weeks after therapy. The response to combination therapy was evaluated at 3 months after treatment. The mean period of combination therapy was 6.4+/-4.2 weeks. Therapeutic response was classified as complete (0-1 wet night/week), partial (over 50% reduction of night) and non-responders (less than 50% reduction of night). RESULTS: The cumulative rate of the complete and partial responders was 76.3%. Among the 3 groups, the statistically lowest value of pre-treatment urine osmolality was observed in the complete responder group (p<0.001). Urine osmolality increased in all groups after treatment, however, statistically the greatest difference between pre and post-treatment urine osmolality was observed in the complete responder group (p=0.024). No serious side effects were observed. CONCLUSION: Early morning urine osmolality and change of urine osmolality between pre and post-treatment have predictive values in the response to combined imipramine and desmopressin for treatment of monosymptomatic NE.

BACKGROUND: Left ventricular hypertrophy is common in chronic renal failure patients and may contribute increased risk of cardiovascular morbidity and mortality. We evaluated the left ventricular morphology and function in renal transplant recipients to find the relationship between hemodynamic changes and morphologic and functional improvement after transplantation. METHODS: Serial echocardiographic evaluations were performed in 27 adults(20 men and 7 women) at the time of transplantaion and posttransplantation 1 month and 4 months. The average duration of hemodialysis was 16+/-24 months(mean+/-S.D.). RESULTS: At the time of transplantation, the hematocrit level was 21+/-6% and posttransplantation 1 month and 4 months, that was increased to 39+/-5% and 42+/-7%, respectively(p<0.001). Left ventricular mass index by echocardiography was decreased significantly from 246+/-87g/m2(pre-KT) to 169+/-38g/m2(post-KT 1 month) and 153+/-40g/m2(post-KT 4 months), respectively (p<0.001). Interventricular septal thickness and left ventricular posterior wall thickness were decreased significantly after 4 months of transplantation. Left ventricular systolic and diastolic dimensions were also decreased significantly after 1 month and 4 months of transplantation. Left ventricular volumes and cardiac output were also decreased significantly. But A/E ratio, ejection fraction and fractional shortening did not change significantly. CONCLUSION: These findings showed that pretransplant high output state was resolved radipidly(within 1 month) but the diastolic function did not improved after transplantation 1 month and 4 months.

PURPOSE: To report clinical characteristics of thyroid-associated ophthalmopathy (TAO) in patients who previously underwent total thyroidectomy for thyroid cancer or a benign mass of the thyroid. MATERIALS AND METHODS: Of the patients who were diagnosed with TAO from March 2008 to March 2012, we performed a retrospective chart review on those who had undergone total thyroidectomy for thyroid cancer or a benign mass of the thyroid before the occurrence of ophthalmopathy. RESULTS: Of the 206 patients diagnosed with TAO, seven (3.4%) met the inclusion criteria. The mean age of the subjects was 47.4 years, and all were female. Six patients were diagnosed with papillary thyroid cancer, and one was diagnosed with a benign mass. The duration between total thyroidectomy and onset of TAO ranged from 3-120 months (median 48 months). Ophthalmic manifestations varied among cases. Except for the patient who was diagnosed with a benign mass, all patients showed hyperthyroid status and were under Synthroid hormone treatment at the time of TAO development. Five of these six patients had positive levels of thyroid-stimulating hormone (TSH) receptor autoantibodies. CONCLUSION: TAO rarely develops after total thyroidectomy, and the mechanism of TAO occurrence is unclear. However, most patients showed abnormalities in thyroid function and TSH receptor autoantibodies.

PURPOSE: This study was performed to investigate the effects of intravesical instillation of cyclooxygenase-2 (COX-2) inhibitors on the cyclophosphamide-induced overactive bladder. MATERIALS AND METHODS: The 40 Sprague-Dawley rats were divided into 3 groups; the control group, the overactive group, and the COX-2 inhibitor treated group. Cystometrograms (CMG) were performed and the contraction interval, inter-contraction interval, contraction time and contraction pressure were measured. After CMG, the bladders of each group were dissected out, and weighed. RESULTS: On CMG, the contraction interval and inter-contraction interval for the overactive group were significantly decreased compared with the control group. After treatment with COX-2 inhibitor, the contraction interval and inter-contraction interval were significantly increased compared with the overactive group (p<0.05). The contraction time in the overactive group was significantly increased compared with the control group, and it was also decreased in the COX-2 inhibitor treated group compared with the overactive group (p<0.05). The contraction pressure in the overactive group and the COX-2 inhibitor treated group were significantly increased compared with the control group. There were no significant differences between the overactive and COX-2 inhibitor treated groups. The bladder weights of the overactive and COX-2 inhibitor treated groups were significantly increased compared with the control group (p<0.05). CONCLUSIONS: Intravesical instillation of COX-2 inhibitor can suppress cyclophosphamide-induced detrusor overactivity. Therefore, intravesical instillation of COX-2 inhibitor may be considered as a possible treatment for the overactive bladder.
