PURPOSE: To describe the early experience of analyzing variations and time trends in bladder volume of the rectal cancer patients who received bladder ultrasound scan. MATERIALS AND METHODS: We identified 20 consecutive rectal cancer patients who received whole pelvic radiotherapy (RT) and bladder ultrasound scan between February and April 2012. Before simulation and during the entire course of treatment, patients were scanned with portable automated ultrasonic bladder scanner, 5 times consecutively, and the median value was reported. Then a radiation oncologist contoured the bladder inner wall shown on simulation computed tomography (CT) and calculated its volume. RESULTS: Before simulation, the median bladder volume measured using simulation CT and bladder ultrasound scan was 427 mL (range, 74 to 1,172 mL) and 417 mL (range, 147 to 1,245 mL), respectively. There was strong linear correlation (R = 0.93, p < 0.001) between the two results. During the course of treatment, there were wide variations in the bladder volume and every time, measurements were below the baseline with statistical significance (12/16). At 6 weeks after RT, the median volume was reduced by 59.3% to 175 mL. Compared to the baseline, bladder volume was reduced by 38% or 161 mL on average every week for 6 weeks. CONCLUSION: To our knowledge, this study is the first to prove that there are bladder volume variations and a reduction in bladder volume in rectal cancer patients. Moreover, our results will serve as the basis for implementation of bladder training to patients receiving RT with full bladder.

BACKGROUND: This study aimed to assess the recent changes of radiation therapy (RT) modalities in Korea. In particular, we focused on intensity-modulated radiation therapy (IMRT) utilization as the main index, presenting the application status of advanced RT. METHODS: We collected information from the Korean Health and Insurance Review and Assessment Service data based on the National Health Insurance Service claims and reimbursements records by using treatment codes from 2010 to 2016. We classified locating region of each institution as capital vs. non-capital areas and metropolitan vs. non-metropolitan areas to assess the regional difference in IMRT utilization in Korea. RESULTS: IMRT use has been steadily increased in Korea, with an annual increase estimate (AIE) of 37.9% from 2011 to 2016 (P < 0.001) resulting in IMRT being the second most common RT modality following three-dimensional conformal radiotherapy. In general, an increasing trend of IMRT utilization was observed, regardless of the region. The rate of AIE in the capital areas or metropolitan areas was higher than that in non-capital areas or non-metropolitan areas (40.7% vs. 31.9%; P < 0.001 and 39.7% vs. 29.4%; P < 0.001, respectively). DISCUSSION: The result of our survey showed that IMRT has become one of the most common RT modalities. IMRT is becoming popular in both metropolitan and non-metropolitan areas, while metropolitan area has faster AIE possibly due to concentration of medical resources and movement of advanced patients.

OBJECTIVE: To investigate the association of genetic background between MTHFR C677T genotype and infertile females with polycystic ovarian syndrome. MATERIALS AND METHODS: We compared 86 infertile females with polycystic ovarian syndrome (PCOS) with 100 healthy fertile females with one or more offspring. Pyrosequencing analysis for MTHFR C677T variation was performed on polymerase chain reaction (PCR) product of study group. To validate pyrosequencing data of C677T variation for randomly selected 50 samples, we compared the pyrosequencing result with the PCR-RFLP (Restriction Fragment Length Polymorphism) result of MTHFR C677T genotype. RESULTS: The prevalence of the C677T mutant homozygous (TT) was significantly lower (p=0.0085) in females with PCOS (8.14%) than in fertile females (21.00%). MTHFR 677 TT genotype had a decreased risk (3.7-fold) of PCOS compared with wild type (MTHFR 677 CC). CONCLUSION: Our data support a role for MTHFR mutant homozygous (677 TT) genotype in reducing risk in Korean infertile females with Polycystic ovarian syndrome.

The present study was undertaken to investigate the influence of hypothermia on endothelium-independent vascular smooth muscle contractility and to determine the mechanism underlying the relaxation. Denuded aortic rings from male rats were used and isometric contractions were recorded and combined with molecular experiments. Hypothermia significantly inhibited fluoride-, thromboxane A2-, phenylephrine-, and phorbol ester-induced vascular contractions regardless of endothelial nitric oxide synthesis, suggesting that another pathway had a direct effect on vascular smooth muscle. Hypothermia significantly inhibited the fluoride-induced increase in pMYPT1 level and phorbol ester-induced increase in pERK1/2 level, suggesting inhibition of Rho-kinase and MEK activity and subsequent phosphorylation of MYPT1 and ERK1/2. These results suggest that the relaxing effect of moderate hypothermia on agonist-induced vascular contraction regardless of endothelial function involves inhibition of Rho-kinase and MEK activities.

MATERIAL AND METHOD: Esophageal reconstruction by the hypopharyngointestinal anastomosis was done in 7 patients of corrosive upper esophageal stricture at St. Mary's Hospital from August 1995 to January 1997. RESULT: There were one male and six female patients ranging from 20 to 63 years of age. The causative agents were acid in 6 patients and alkali in 1 patient. The esophageal reconstruction was made by hypopharyngcolojejunostomy in 4 patients and hypopharyngocologastrostomy in 3 patients. There were no operative mortalities. One patient developed anastomotic stenosis but others were free from dysphagia. All gained 4 kg to 13 kg of body weight during the follow-up period. CONCLUSION: In this experience right colon and terminal ileum including ileocecal valve was revealed as a good substitute for the esophagus and the esophageal reconstruction by hypopharyngocologastro (jejuno)stomy seems to be a satisfactory method with acceptable morbidity and mortality in corrosive upper esophageal stricture patient.

BACKGROUND/AIM: Recent advances in both diagnosis and treatment have markedly improved the prognosis in patients with hepatocellular carcinoma (HCC). Bone metastasis has become a clinical problem in the treatment of HCC patients. The purpose of this study was to evaluate the palliative effect of radiotherapy for painful bone metastasis from HCC. METHODS: From January 1991 to June 2000, 51 patients (77 sites) with painful bone metastasis from HCC were retrospectively analyzed. Ages ranged from 21 to 80 years (median 55 years). The male:female ratio was 7.5:1. Synchronous or metachronous bone metastasis was seen in 20 (39%) and 31 patients (61%), respectively. The most common symptom of bone metastasis was pain (45 patients, 88%). Twenty-one patients (41%) had a solitary bone metastasis while 30 (59%) had multiple ones. The sites of bone metastasis, in order of frequency, were the vertebra (38), rib (20), and pelvis (19). The total radiation dose ranged from 12.5 to 50 Gy (median 30 Gy). The Wisconsin Brief Pain Questionnaire was used to evaluate pain response. RESULTS: The overall 1 and 2 year survival rates from the time of bone metastasis were 15% and 4%, respectively. The median survival time was 5 months. Intrahepatic stage(p=0.014), and metastasis to other organs(p=0.019) were significant prognostic factor for survival by univariate analysis. There was, however, no independent prognostic factor on multivariate analysis. Pain relief after radiotherapy was achieved for 56 sites (73%). CONCLUSION: The expected life span (median 5 months) in this group of patients suggests a strong necessity for effective treatment for symptomatic palliation. Radiation therapy was effective in pain palliation for bone metastasis from HCC, and this could improve patients' quality of life.

Undifferentiated carcinomas with osteoclast-like giant cells are rare pancreatic and periampullary neoplasms that mimic giant cell tumors of bone morphologically. Recently, we experienced an osteoclast-like giant cell tumor arising in the tail of the pancreas. A 76-year-old male was admitted with epigastric discomfort and indigestion. Abdominal computed tomography (CT) and abdominal magnetic resonance imaging (MRI) showed a 3x3-cm mass containing necrotic and hemorrhagic areas in the tail of the pancreas. A distal pancreatectomy and splenectomy were performed. Histological examination showed tumor cell components consisting of mononuclear pleomorphic cells admixed with osteoclastic giant cells. The final diagnosis was undifferentiated carcinoma with osteoclast-like giant cells with ductal adenocarcinoma in the pancreas.

OBJECTIVE: This study was designed to assess the effect of extracorporeal magnetic innervation (ExMI) therapy for urinary incontinence and sexual function. METHODS: Fifty female patients with urinary incontinence were prospectively studied. Their mean age was 47.2 years, and the mean duration of symptoms was 6.7 years. All they had a history of previous vaginal delivery and mixed urinary incontinence symptoms. Evaluation before treatment included urine analysis and culture for excluding urinary infection, physical examination including neurologic and gynecologic evaluation for structural abnormality, vaginal pressure measurement with perineometer and quality of life survey with questionnaire. For the treatment, the patients were seated fully clothed in a Neocontrol chair with a magnetic field therapy. Treatment sessions were for 20 minutes, twices a week for the average 8 weeks. At one week after ExMI therapy, vaginal pressure measurement and quality of life survey (including questions of patient and patient's husband for satisfaction degree of their sexual life) were repeated. The comparison of incontinence symptoms, qulity of life (including sexual life) and vaginal pressure measurement before and after ExMI therapy were assessed. RESULTS: The results were as follows 1) The mean of urge incontinence symptoms score was increased 3.06 to 4.60 after ExMI (P<0.05). 2) The mean of stress incontinence symptoms score was increased 3.08 to 4.57 after ExMI (P<0.05). 3) The mean of quality of life (QoL) score was increased 3.36 to 4.77 after ExMI (P<0.05). 4) The mean of quality of sexual life (QoSL) score was increased 3.70 to 4.92 after ExMI (P<0.05). 5) The mean of vaginal pressure and duration of pelvic floor muscle contraction after ExMI were increased with startistical significance. CONCLUSION: Our results suggested that ExMI therapy might be effective for not only urinary incontinence but also improvement of sexual function.

Laparoscopic surgery has recently extended its indications and it has also become an acceptable surgical approach for splenectomy. In the last five years, we have performed 40 laparoscopic splenectomies for immune thrombocytopenic purpura. Thirty-five patients were female and 5 patients were male. The mean age was 34, varying from 17 to 56. After learning to perform laparoscopic splenectomy with five ports, we are now usually using three or four ports in a right lateral kidney position. There was no case of conversion to exploratory laparotomy. The mean hospital stay was 7 days. There was no perioperative mortality; but in 2 cases we had postoperative subphrenic abscesses which were successfully managed by catheter drainage. Since undergoing laparoscopic splenectomy, 28 patients (70%) were weaned effectively from their steroid medications. Eight patients (20%) have been on small doses of steroid, and 4 patients (10%) have been on the same doses of steroid with no response. The patient group with rapidly increasing platelet count after splenectomy showed a statistically significant relation with the complete response group (p < 0.001). Laparoscopic splenectomy is a safe and reasonable operative procedure for patients with immune thrombocytopenic purpura.
