Cardiovascular disease is the most frequent cause of death in patients with acromegaly. Recently, long-term treatment with a somatostatin analogue (Sandostatin LAR) has been shown to be effective in controlling growth hormone (GH) and insulin like growth factor-1 (IGF-1) hypersecretion in most patients with acromegaly. Along with the effectiveness in the hormone profile, Sandostatin LAR has been reported to be effective for tumor mass shrinkage and clinical symptom improvement. We have encountered a female acromeglic patient with severe dilated cardiomyopathy and the patient was treated with Sandostatin LAR After treatment for 12 months, as seen by follow up echocardiography, the overall cardiac function was significantly improved. We report the case with a review of the literature.

BACKGROUND AND OBJECTIVES: Genomic imprinting modulates growth and development in mammals and is associated with genetic disorders. Although uniparental embryonic stem cells have been used to study genomic imprinting, there is an ethical issue associated with the destruction of human embryos. In this study, to investigate the genomic imprinting status in human neurodevelopment, we used human uniparental induced pluripotent stem cells (iPSCs) that possessed only maternal alleles and differentiated into neural cell lineages. METHODS: Human somatic iPSCs (hSiPSCs) and human parthenogenetic iPSCs (hPgiPSCs) were differentiated into neural stem cells (NSCs) and named hSi-NSCs and hPgi-NSCs respectively. DNA methylation and gene expression of imprinted genes related neurodevelopment was analyzed during reprogramming and neural lineage differentiation. RESULTS: The DNA methylation and expression of imprinted genes were altered or maintained after differentiation into NSCs. The imprinting status in NSCs were maintained after terminal differentiation into neurons and astrocytes. In contrast, gene expression was differentially presented in a cell type-specific manner. CONCLUSIONS: This study suggests that genomic imprinting should be determined in each neural cell type because the genomic imprinting status can differ in a cell type-specific manner. In addition, the in vitro model established in this study would be useful for verifying the epigenetic alteration of imprinted genes which can be differentially changed during neurodevelopment in human and for screening novel imprinted genes related to neurodevelopment. Moreover, the confirmed genomic imprinting status could be used to find out an abnormal genomic imprinting status of imprinted genes related with neurogenetic disorders according to uniparental genotypes.

PURPOSE: Psychometric properties of the overactive bladder questionnaire (OAB-q) were recently examined. However, since the cross-cultural adaptation of a non-English version of the OAB-q has never been demonstrated, we evaluated the psychometric properties of a Korean version of the OAB-q in a Korean population with OAB. METHODS: A prospective cohort study involving 116 women with 58 OAB and 58 control subjects was performed and convergent validity was assessed. Total and subscale OAB-q scores of the control and OAB groups were compared to their sensitivity to score changes before and after administering anti-cholinergic medication for 12 weeks. Short form 36 and King's health questionnaire (KHQ) were also used for comparison or correlation. RESULTS: Assessment of face validity showed that the Korean version of the OAB-q was reasonable with OAB-q subscale scores being significantly different between the control and patient groups. Significant correlation (range, -0.29 to -0.81) was found between the OAB-q scores and KHQ results for the OAB patients. Cronbach's alpha coefficients (range, 0.77 to 0.95) indicated excellent internal consistency and test-retest analysis involving 35 OAB patients showed that each questions as well as subscale scores were reproducible. Each score of OAB-q also showed statistically significant sensitivity to changes following anti-muscarinic treatment for OAB (n=27, P<0.001 except for social, P=0.059). CONCLUSIONS: The Korean version of the OAB-q is a valid and reliable instrument to measure outcomes in Korean patients with OAB.

PURPOSE: The aim of this study was to assess the safety of TME with pelvic autonomic nerve preservation in male rectal cancer patients in terms of voiding and sexual function. METHODS: We performed uroflowmetry using Urodyn (Dantec, Denmark) and a standard questionnaire employing the IIEF (International Index of Erectile Function) and the IPSS (International Prostate Symptom Score) pre- and postoperatively in 68 male rectal cancer patients. RESULTS: There were significant differences of mean maximal flow rate and voided volume before and after surgery (18.9+/-5.7 vs 13.7+/-7.0, 240+/-91.9 vs 143+/-78, P<0.05, P<0.05), respectively. But, there was no difference of residual volume before and after surgery (4.4 2.6 vs 8.1 4.4, P>0.05). The total IPSS (International Prostate Symptom Score) was increased after surgery from 6.2+/-5.8 to 9.8+/-5.9 (P<0.05). There were no changes of score for one of each seven IPSS items in from 49 patients (73.5 percent) to 61 patients (89.7 percent). Five IIEF (International Index of Erectile Function) domain score (erectile function, intercourse satisfaction, orgasmic function, sexual desire and overall satisfaction) was statistically decreased after surgery (18.2+/-9.3 vs 13.5+/-9.0, 8.4+/-4.2 vs. 4.4+/-2.9, 5.8+/-2.9, vs. 4.4+/-2.9, 6.1+/-2.4 vs. 4.8+/-2.0, 6.1+/-2.2 vs. 4.5+/-2.3, P<0.05, respectively. Erection was possible in 55 patients (80.9 percent), but penetration ability was possible in 51 patients (75 percent). Complete inability for erection and intercourse was observed in 3 patients (5.5 percent). Retrograde ejaculation was noted in 9 patients (13.2 percent). IIEF domains such as sexual desire and overall satisfaction were markedly decreased in 39 patients (57.4 percent), 43 patients (63.2 percent), respectively. Multiple regression analysis of factors affecting postoperative sexual dysfunction showed that over 60 years (sexual desire: P=0.019), within 6 months (erectile function: P=0.04, intercourse satisfaction: P=0.011, orgasmic function: P=0.03), lower rectal cancer (erectile function: P=0.02, intercourse satisfaction: P=0.036, orgasmic function: P=0.027) were significant factors. CONCLUSIONS: TME with pelvic autonomic nerve preservation technique showed a safety and comparable data in preserving sexual and voiding function. The IPSS and IIEF questionnaire were useful and more investigative in assessing urinary and sexual function.

Carbon monoxide (CO) is a well-known chemical asphyxiant, which causes tissue hypoxia with prominent neurological injury. Therapeutic hypothermia (TH) has been shown to be an effective neuroprotective method in post-cardiac arrest patients. A 26-year-old man presented to the emergency department with severe CO poisoning. On arrival, the patient was comatose. His vital signs were blood pressure, 130/80 mm Hg; heart rate, 126/min; respiratory rate, 26/min; body temperature, 36degrees C; and O2 saturation, 94%. Initial carboxyhemoglobin was 45.2%. Because there was no available hyperbaric chamber in our local area, he was intubated and treated with TH. The target temperature was 33 +/- 1degrees C for 24 hours using an external cooling device. The patient was then allowed to reach normothermia by 0.15-0.25degrees C/hr. The patient was discharged after normal neurological exams on day 11 at the hospital. TH initiated after exposure to CO may be an effective prophylactic method for preventing neurological sequelae.

PURPOSE: To conduct a nationwide survery on the principles in radiotherapy for rectal cancer, and develop the framework of a database of Korean Patterns of Care Study. MATERIALS AND METHODS: A consensus committee was established to develop a tool for measuring the patterns in radiotherapy protocols for rectal cancer. The panel was composed of radiation oncologists from 18 hospitals in Seoul Metropolitan area. The committee developed a survey format to analyze radiation oncologist's treatment principles for rectal cancer. The survey items developed for measuring the treatment principles were composed of 1) 8 eligibility criteria, 2) 20 items for staging work-ups and prognostic factors, 3) 7 items for principles of combined surgery and chemotherapy, 4) 9 patient set-ups, 5) 19 determining radiation fields, 6) 5 radiotherapy treatment plans, 7) 4 physical/laboratory examination to monitor a patient's condition during treatment, and 8) 10 follow-up evaluations. These items were sent to radiation oncologists in charge of gastrointestinal malignancies in all hospitals (48 hospitals) in Korea to which 30 replies were received (63%). RESULTS: Most of the survey items were replied to without no major differences between the repliers, but with the following items only 50% of repliers were in agreement:1) indications of preoperative radiation, 2) use of endorectal ultrasound, CT scan, and bone scan for staging work-ups, 3) principles of combining chemotherapy with radiotherapy, 4) use of contrast material for small bowel delineation during simulation, 5) determination of field margins, and 6) use of CEA and colonoscopy for follow-up evaluations. CONCLUSION: The items where considerable disagreement was shown among the radiation oncologists seemed to make no serious difference in the treatment outcome, but a practical and reasonable consensus should be reached by the committee, with logical processes of agreement. These items can be used for a basic database for the Patterns of Care Study, which will survey the practical radiotherapy patterns for rectal cancer in Korea.

The authors analysed 2,653 cases of transthoracic fine needle aspiration cytology of the lung to evaluate the diagnostic accuracy and its limitation. A comparison was made between the original cytologic and the final histologic diagnoses on 1,149 cases from 1,074 patients. A diagnosis of malignancy was established in 38.3% benign in 48.1%, atypical lesion in 2.3%, and inadequate one in 11.9% of the cases. Statistical data on cytologic diagnoses were as follows; specificity 98.9%: sensitivity of procedure, 76.8%: sensitivity of diagnosis, 95.5%: false positive 5 cases: false negative 18 cases: predictive value for malignancy, 98.8%: predictive value for benign lesion, 79.5%: overall diagnostic efficiency, 87.5%: typing accuracy in malignant tumor, 80%.
