In this study, the effects of high-intensity-focused ultrasound (HIFU) treatment on benign uterine tumor patients were examined. A total of 333 patients diagnosed with fibroids or adenomyosis using diagnostic sonography, treated with HIFU between February 4, 2010 and December 29, 2014 at a hospital in Korea, and followed up for three or six months were selected for this study. Their benign uterine tumor volume was measured, and the effects of HIFU treatment on the volume were analyzed according to age, disease, fertility, and treatment duration. The volume of benign tumors of the uterus changed by age in all age groups after conducting HIFU treatment for 3 and 6 months, respectively. The rate of decrease in individuals' in their twenties was the largest, at 64.9%. When the decreasing volume of benign tumors of the uterus was analyzed by type of disease, the treatment efficacy for adenomyosis was the best, with a decrease of 164.83 cm3 after 6 months. Myoma had the fastest decreasing rate, at 68.5%. When evaluated on the basis of fertility, the volume of benign tumors of the uterus continued to decrease until 6 months after completing all procedures. The volume has continued to decrease for 6 months after all procedures. This study showed that HIFU treatments for uterine fibroid and adenomyosis is an effective non-invasive therapy via reducing the benign uterine tumor volume. Therefore, the HIFU method might replace other conventional treatment methods. © 2016 The Korean Academy of Medical Sciences. Source

Radiation Effects and Defects in Solids | Year: 2015

This study examined the effects of entrance surface dose (ESD) on the abdomen and pelvis of the patient when undergoing chest computed tomography (CT) procedure, and evaluated the effects of ESD reduction depending on the location of radiation shield. For CT scanner, the 64-slice multi-detector computed tomography was used. The alderson radiation therapy phantom and optically stimulated luminescence dosimeter (OSLD), which enabled measurement from low to high dose, were also used. For measurement of radiation dose, the slice number from 9 to 21 of the phantom was set as the test range, which included apex up to both costophrenic angles. A total of 10 OSLD nanoDots were attached for measurement of the front and rear ESD. Cyclic tests were performed using the low-dose chest CT and high-resolution CT (HRCT) protocol on the following set-ups: without shielding; shielding only on the front side; shielding only on the rear side; and shielding for both front and rear sides. According to the test results, ESD for both front and rear sides was higher in HRCT than low-dose CT when radiation shielding was not used. It was also determined that, compared to the set-up that did not use the radiation shield, locating the radiation shield on the front side was effective in reducing front ESD, while locating the radiation shield on the rear side reduced rear ESD level. Shielding both the front and rear sides resulted in ESD reduction. In conclusion, it was confirmed that shielding the front and rear sides was the most effective method to reduce the ESD effect caused by scatter ray during radiography. © 2015 Taylor & Francis Source

Abstract Objectives This study aimed to assess the therapeutic outcomes of patients with uterine fibroid or adenomyosis treated by ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation at Incheon Christian Hospital, Korea. Methods This study included 618 patients, of which 272 suffered from uterine fibroid and 346 suffered from adenomyosis. Treatment was administrated using the Model Haifu JC Focused Ultrasound Tumor Therapeutic System (Chongqing Haifu Technology, Chongqing, China) under real-time ultrasound guidance. A follow-up was conducted on volume change as well as on symptom improvement using the Symptom Severity Score (SSS) and Uterine Fibroid Symptom and Quality of Life (UFS-QOL) after treatment. Result The uterine fibroid volume reduction rates (%) were 58.08%, 66.18%, and 77.59% at 3, 6, and 12 months after treatment, respectively. The SSS reduction rates (%) were 55.58%, 52.76%, and 50.39% by 3, 6, and 12 months, respectively. The UFS-QOL score increasing rates (%) were 42.66%, 43.50%, and 43.45% by 3, 6, and 12 months, respectively. The uterine volume reduction rates (%) for adenomyosis were 43.99%, 47.01%, and 53.98% by 3, 6, and 12 months, respectively. The SSS reduction rates (%) for adenomyosis were 55.61%, 52.38%, and 57.98% by 3, 6, and 12 months, respectively. The UFS-QOL score increasing rates (%) for adenomyosis UFS-QOL score were 80.06%, 69.39%, and 85.07% by 3, 6, and 12 months, respectively. Conclusion We conclude that USgHIFU treatment for uterine fibroid and adenomyosis is an effective non-invasive therapy via the assessment of fibroid volume reduction, symptom improvement, UFS-QOL score increase, and acceptable level of side effects. Although preliminary experience of HIFU is encouraging, well-designed prospective trials and more clinical experiences are needed to ascertain the efficacy and safety of this new treatment. © 2015 Published by Elsevier B.V.

This report describes the efficacy of combined use of aripiprazole in the treatment of a patient with clozapine induced enuresis. Aripiprazole acts as a potential dopamine partial agonist and the dopamine blockade in the basal ganglia might be one of the causes of urinary incontinence and enuresis. We speculate that aripiprazole functioned as a D2 agonist in hypodopaminergic state of basal ganglia caused by clozapine and maintained dopamine level that would improve enuresis ultimately. © 2010 The Korean Academy of Medical Sciences.

Background/Aims: We evaluated the usefulness of cystatin C as a prognostic marker in patients with liver cirrhosis and normal serum creatinine. Methodology: We retrospectively analyzed prospectively enrolled patients with liver cirrhosis and normal serum creatinine from February 2007 to March 2008. We checked liver function and kidney variables including serum creatinine, cystatin C and glomerular filtration rate from 51Cr-EDTA on the same day for all patients. The endpoints of the study were either development of hepatorenal syndrome or mortality. Results: In total, 112 patients with liver cirrhosis were enrolled in the study (87 men and 25 women, age 52±12 years). Twelve (11%), 59 (53%) and 41 (36%) patients were in Child-Pugh class A, B and C, respectively. Cystatin C was better correlated with glomerular filtration rate from 51Cr-EDTA than creatinine. The 1-year cumulative incidence of hepatorenal syndrome and the 1-year survival rate of patients were 20.5% and 79.5%, respectively. Cystatin C, Model for End-Stage Liver Disease and serum sodium were the independent predictive factors for hepatorenal syndrome. Cystatin C, serum sodium and prothrombin time were the independent factors for predicting survival. Conclusions: In patients with liver cirrhosis and normal creatinine levels, cystatin C is a useful marker for predicting hepatorenal syndrome and survival. © H.G.E. Update Medical Publishing S.A.
