PURPOSE: The growth hormone receptor(GHR) is essential for the actions of growth hormone on postnatal growth and metabolism. GHR transcripts are characterized by the presence of disparate 5'untranslated exons. In contrast to L1 transcript, factors regulating the expression of the GC rich L2 transcript have remained unidentified. The purpose of this study is in order to characterize the mechanisms regulating expression of the L2 transcript in the murine GHR gene METHODS: Transient transfection experiments including deletional analysis and co-transfection assay were performed to find a region containing promoter activity in the L2 5'flanking sequence using BNCL2(mouse liver) cells, CV-1(African green monkey kidney) cells, HRP.1 trophoblasts and Drosophila Schneider(SL2) cells. Sequencing analysis was performed to find the region contained consensus binding sites for transcription factors. Standard gel shift(Electrophoretic mobility shift assay, EMSA) and supershift analysis using liver nuclear extracts was performed to establish proteins(transcription factors) bound this regulatory element. RESULTS: The 5'flanking region of the L2 untranslated region(UTR) exhibited promoter activity in BNCL2(mouse liver), CV-1(monkey kidney) cells and HRP.1 trophoblasts. Deletional analyses indicated the presence of a Sp binding site important for transcription of the L2 UTR and localized the major regulatory region within 75 bp of the 5'transcription start site. Sequencing analyses revealed the region contained consensus binding sites for the Sp family of transcription factors. EMSA and supershift EMSA revealed that in mouse liver nuclear extracts that Spl and Sp3 bound to this cis-element. Functional studies in Drosophila SL2 cells and BNCL2(mouse liver) cells established the ability of Sp3 and Sp1 to stimulate transcriptional activity via this cis-element. Functional studies in Drosophila SL2 cells demonstrated a functional interaction between Sp3 and Sp1 at this DNA-binding site. CONCLUSION: Sp family transcription factors play a role in regulation of L2 transcript gene expression in the 5'flanking region of the murine GHR gene.

BACKGROUND: External ventricular drainage (EVD) is an important procedure for draining excessive cerebrospinal fluid (CSF) and monitoring intracranial pressure. Generally, EVD is performed in the operating room (OR) under aseptic conditions. However, in emergency circumstances, the operation may be performed in the intensive care unit (ICU) to save neuro-critical time and to avoid the unnecessary transfer of patients. In this study, we retrospectively analyzed the risk of EVD-induced CNS infections and their outcomes according to the operating place (ICU versus OR). In addition, we compared mortalities as well as hospital and ICU days between the CNS infection and non-CNS infection groups. METHODS: We reviewed medical records, laboratory data and radiographic images of patients who had received EVD operations between January, 2013 and March, 2015. RESULTS: A total of 75 patients (45 men and 30 women, mean age: 58.7 +/- 15.6 years) were enrolled in this study. An average of 1.4 catheters were used for each patient and the mean period of the indwelling catheter was 7.5 +/- 5.0 days. Twenty-six patients were included in the ICU group, and EVD-induced CNS infection had occurred in 3 (11.5%) patients. For the OR group, forty-nine patients were included and EVD-induced CNS infection had occurred in 7 (14.3%) patients. The EVD-induced CNS infection of the ICU group did not increase above that of the OR group. The ICU days and mortality rate were higher in the CNS infection group compared to the non-CNS infection group. The period of the indwelling EVD catheter and the number of inserted EVD catheters were both higher in the CNS infection group. CONCLUSIONS: If the aseptic protocols and barrier precautions are strictly kept, EVD in the ICU does not have a higher risk of CNS infections compared to the OR. In addition, EVD in the ICU can decrease the hospital and ICU days by saving neuro-critical time and avoiding the unnecessary transfer of patients. Therefore, when neurosurgeons decide upon the operating place for EVD, they should consider the benefits of ICU operation and be cautious of EVD-induced CNS infection.

OBJECTIVES: Periodic limb movement disorder (PLMD) has been debated with regard to its clinical significance and diagnostic criteria. The current diagnostic criterion for PLMD in adults has been changed from periodic limb movement index (PLMI) > 5/ hour to PLMI > 15/hour by the International Classification of Sleep Disorders (ICSD). In this study, we aimed to investigate the changes in polysomnographic sleep variables according to PLMI and to determine the relevance of the diagnostic criterion for PLMD. METHODS: Out of 4195 subjects who underwent standard polysomnography, we selected 666 subjects (370 males and 296 females, aged 47.1 ± 14.8) who were older than 17 years and were not diagnosed with primary insomnia, sleep apnea, narcolepsy, or REM sleep behavior disorder. Subjects were divided into three groups according to PLMI severity: group 1 (PLMI ≤ 5), group 2 (5 < PLMI ≤ 15), and group 3 (PLMI > 15). Demographic and polysomnographic sleep variables and Epworth sleepiness scale (ESS) were compared among the three groups. RESULTS: There were significant differences among the three groups in age and gender. Sleep efficiency (SE) and stage 3 sleep percentage in group 1 were significantly higher than those in groups 2 and 3. The wake after sleep onset (WASO) score in group 1 was significantly lower than those in groups 2 and 3. However, there were no significant differences in SE, stage 3 sleep percentage, or WASO between groups 2 and 3. Sleep latency (SL) in group 1 was significantly lower than that in group 3, but there was no difference in SL between group 2 and group 3. ESS score in group 1 was significantly higher than that in group 3, but there was no difference between group 2 and group 3. Partial correlation analysis adjusted by age showed that PLMI was significantly related to SE and WASO. CONCLUSION: This study suggests that PLMI influences polysomnographic sleep variables. In addition, we found the individuals who did not have PLMD but had PLMI > 5 were not different in polysomnographic sleep variables from the individuals who had PLMD according to the current criterion. These results raise questions about the relevance of the current diagnostic criterion of PLMD.

The following is a report of the anesthetic experience in the surgical management of two cases of surgery for pheochromocytoma performed at Maryknoll Hospital, Busan, between the dates of June and July, 1982, The report covers the pre-surgical tests and the laboratory results on the two cases, which was similar, and the anesthetic agents halothane and enflurane, was used on the cases, respectively. During surgery using the anesthetic agent halothane, which was chosen because of the high blood pressure of the patient, and our effect to control it, we encountered dangerous arrythmia. In the case where enflurane was the anesthetic agent uaed, it was found that while the blood pressure of the patient was more difficult to control, the incidence of arrythmias was much less frequent. In one of the cases, becsuse of hemorrhage from the operative site during the immediate surgical period, re-exploration was done with adequate replacement of whole blood and catecholamines administered as needed during the anesthetic management. In comparing the two cases, the one case in which alpha-sdrenergic blockers were not administered during the pre-surgical period, when compared with the case in which the the blockers were used, showed, after removal ef the tumor, a decrease in the need for alpha-adrenergic stimulators.

PURPOSE: We designed this study to identify and suggest the reasonable timing of adjuvant radiotherapy in the treatment of uterine carcinosarcoma according to the surgical intent and patterns of progression. MATERIALS AND METHODS: We retrospectively analyzed a total of 50 carcinosarcoma patients diagnosed between 1995 and 2010. Among these 50 patients, 32 underwent curative surgery and 13 underwent maximal tumor debulking surgery. The remaining five patients underwent biopsy only. Twenty-six patients received chemotherapy, and 15 patients received adjuvant radiotherapy. RESULTS: The median follow-up period was 17.3 months. Curative resection (p < 0.001) and stage (p < 0.001) were statistically significant factors affecting survival. During follow-up, 30 patients showed progression. Among these, eight patients (16.0%) had loco-regional progression only. The patients who had received adjuvant radiotherapy did not show loco-regional progression, and radiotherapy was a significant negative risk factor for loco-regional progression (p = 0.01). The time to loco-regional progression was much earlier for non-curative than curative resection (range, 0.7 to 7.6 months vs. 7.5 to 39.0 months). CONCLUSION: Adjuvant radiotherapy in the treatment of carcinosarcoma might be related to a low loco-regional progression rate. Radiotherapy should be considered in non-curatively resected patients as soon as possible.

Juxtaductal coarctation is usually distal to the origin of the left subclavian artery, occasionally the orifice of the subclavian artery is involved in the coarctation and partially obstructed. An anomalous origin of the right subclavian artery from the descending aorta below the coarcted segment is also occasionally encountered. Reversed vertebral artery flow to a subclavian artery arising at or below a coarctation may produce the subclavian steal syndrome. Rarely both subclavian arteries arise beyond the coarctation. These abnormal subclavian arteries are important in clinical diagnosis and treatment. We report a case of Turner syndrome with coarctation, which present as juxtaductal type and the left subclavian artery from the descending aorta below the coarcted segment with reversed vertebral artery flow to a subclavian artery producing the subclavian steal syndrome. Resecton of coarctation segment and end-to-end anastomosis was successfully performed after transfer of left subclavian artery to distal segment of descending aorta.
