PURPOSE: This study aimed to identify factors influencing intra-operative core body temperature (CBT), and to develop a predictive model for intra-operative CBT in laparoscopic abdominal surgery. METHODS: The prospective observational study involved 161 subjects, whose age, weight, and height were collected. The basal pre-operative CBT, pre-operative blood pressure, and heartbeat were measured. CBT was measured 1 hour and 2 hours after pneumoperitoneum. RESULTS: Explanatory factors of intra-operative hypothermia (<36℃) were weight (β=.361, p<.001) and pre-operative CBT (β=.280, p=.001) 1 hour after pneumoperitoneum (Adjusted R2=.198, F=7.56, p<.001). Weight was (β=.423, p<.001) and pre-operative CBT was (β=.206, p=.011) 2 hours after pneumoperitoneum (Adjusted R2=.177, F=5.93, p<.001). The researchers developed a predictive model for intra-operative CBT (℃) by observing intra-operative CBT, body weight, and pre-operative CBT. The predictive model revealed that intra-operative CBT was positively correlated with body weight and pre-operative CBT. CONCLUSION: Influence of weight on intra-operative hypothermia increased over time from 1 hour to 2 hours after pneumoperitoneum, whereas influence of pre-operative CBT on intraoperative hypothermia decreased over time from 1 hour to 2 hours after pneumoperitoneum. The research recommends pre-warming for laparoscopic surgical patients to guard against intra-operative hypothermia.

PURPOSE: To compare electroretinogram (ERG) waveforms acquired using a ganzfeld stimulator and a Fresnel ganzfeld stimulator. METHODS: ERGs were recorded with a ganzfeld stimulator and a Fresnel ganzfeld stimulator from both eyes of 25 volunteers. Peak-to-trough amplitudes and peak implicit times were compared between both eyes and between a ganzfeld stimulator and a Fresnel ganzfeld stimulator. ERGs taken from the sitting and supine positions were also compared using the Fresnel ganzfeld stimulator. RESULTS: There was no statistically significant difference between the Fresnel ganzfeld stimulator and dome-shaped ganzfeld stimulator in amplitude and implicit time of dark adapted 0.01, 3.0 ERG, photopic 3.0 ERG, photopic 3.0 flicker. The differences in amplitude and implicit time between the right and left eyes were not influenced by the Fresnel ganzfeld stimulator. Additionally, no differences were observed in ERGs obtained from the sitting and supine positions using the Fresnel ganzfeld stimulator. CONCLUSIONS: The newly developed ganzfeld stimulator with a sealed Fresnel lens can be considered as a reliable alternative method for measuring ERGs. Fresnel ganzfeld stimulator is useful for patients having problems with mobility or uncooperative children.

Hepatitis A can cause serious illness among adolescents and adults with low vaccination coverage. Even though hepatitis A vaccine is one of the strong candidates for Korean national immunization program, adolescents aged older than 12 yr would not benefit. Our purpose was to assess the willingness and analyze the correlates of Korean mothers for hepatitis A (HepA) vaccination to develop strategies for HepA vaccination. A national telephone survey on 800 mothers with children aged 7-18 yr was conducted with random-digit dialing method. Sixty-two percent and 92% of the mothers reported that they were willing to HepA vaccination at current cost and at half of the current cost, respectively. However, at current cost, only 79% wished to vaccinate their child in an epidemic and 32% wished to vaccinate promptly. Having two or more children, not having future plans to send the child overseas, and low family income were significantly associated with not willing to HepA vaccination. Low perception of the susceptibility for hepatitis A and perception of the current cost as barrier increased the odds of unwillingness to vaccination at current cost and to prompt vaccination. The mothers' willingness to HepA vaccination for the children aged 7-18 yr in Korea was not very high at current cost and associated socioeconomic status and health-belief. Targeted intervention or strategies are needed to increase the HepA vaccination rate among children in Korea.

PURPOSE: To investigate the incidence and predictive factors associated with the development of chronic kidney disease (CKD) in patients undergoing curative surgery for renal cell carcinoma. MATERIALS AND METHODS: From 2003 to 2010, we retrospectively investigated 108 patients undergoing partial nephrectomy or radical nephrectomy (RN) for renal tumors with a preoperative glomerular filtration rate (GFR)> or =60. The GFR was calculated by use of the four-variable modification of diet in renal disease (MDRD) formula. CKD was defined as an estimated GFR (eGFR) less than 60 mL/min per 1.73 m2. Demographic and clinicopathologic parameters were evaluated by using the chi-square and Student t-tests and multivariate regression analysis to determine the variables independently associated with the development of postoperative CKD. RESULTS: Of the 108 patients without preoperative CKD, CKD developed in 43 patients (39.8%). In the analysis of clinical factors between patients with and those without CKD development, gender, body mass index, diabetes mellitus, hypertension, and tumor size were not significant clinical factors. Statistical significance for CKD development was found for age of 60 years or greater (p=0.013), decreased preoperative eGFR (p<0.001), and RN group (p<0.001). In the multivariate analysis, decreased preoperative eGFR (p=0.001) and RN group (p=0.002) were significant independent predictors. CONCLUSIONS: The results of our study show that decreased preoperative renal function and RN were significant independent predictors of postoperative CKD. In patients who had a relatively decreased preoperative eGFR, especially when estimated by use of the MDRD formula, nephron-sparing surgery should be considered for the treatment of small renal tumors.

PURPOSE: It is important to diagnose paragonimiasis in early active stage because it can be dured by chemotherapy. However, it is difficult to make a correct diagnosis of cerebral paragonimiasis in the early active stage, and the radiographic findings of cerebral paragonimiasis have been rarely reported. Thus, this experimental study was designed to produce early active cerebral paragonimiasis and to demonstrate radiologic-pathologic correlations. MATERIALS AND METHODS: In 8 cats, 7-8 metacercariae of Paragonimus westerrnani were directly introduced into the brain parenchyma of each cat's after trephination of the skull. In anogher 16 cats, the juvenile worms and the adult worms that had developed for varying periods (2 weeks, 4 weeks, 6 weeks, 8 weeks and 12 weeks) in the lunges of another cats were introduced into the brain parenchyma of each cat's with the same procedures described above. Follw-up MR images and chest radiographs were obtained at 2 days, 1 weeks, 2 weeks, 4 weeks and 8 weeks after innoculation. The autopsies and histopathological examinations of the cat's brain were undertaken in 22 cats. In 9 cats that were suspected with pulmonary lesions on chest radiograph, the soft tissue radiographs of inflated-fixed lungs were obtained. RESULTS: In one cat with innoculation of adult worm, acute suppurative inflammation of the brain parenchyma was demonstrated. But the other cats with innoculction of adult worm or juvenile worm and the cats with innoulation of metacercaris did not reveal any evidence of acute cerebral paragonimiasis. More than half of the introduced metacercariae(5 out of 8 cats) were found in the lung parenchyma, while only 25%(4 out of 16 cats) of the adult worm innoculated cats were. CONCLUSION: Acute suppurative inflammation suggesting acute stage cerebral paragonimiasis was obtained in one case of adult worm innoculated cat. Most of the innoculated metacercariae and some of the juvenile worms or adult worms were migrated to the lungs.

PURPOSE: Serum level of 25-hydroxyvitamin D (25-OHD) is considered as the most appropriate marker of vitamin D status. However, only a few studies have investigated the relationship between 25-OHD and parathyroid hormone (PTH) in children. To this end, this study was aimed at evaluating the lowest 25-OHD level that suppresses the production of parathyroid hormone in children. METHODS: A retrospective record review was performed for children aged 0.2 to 18 years (n=193; 106 boys and 87 girls) who underwent simultaneous measurements of serum 25-OHD and PTH levels between January 2010 and June 2014. RESULTS: The inflection point of serum 25-OHD level for maximal suppression of PTH was at 18.0 ng/mL (95% confidence interval, 14.3–21.7 ng/mL). The median PTH level of the children with 25-OHD levels of <18.0 ng/mL was higher than that of children with 25-OHD levels ≥ 18.0 ng/mL (P<0.0001). The median calcium level of children with 25-OHD levels<18.0 ng/mL was lower than that of children with 25-OHD levels≥18.0 ng/mL (P=0.0001). The frequency of hyperparathyroidism was higher in the children with 25-OHD levels<18.0 ng/mL than in the children with 25-OHD levels≥18.0 ng/mL (P<0.0001). Hypocalcemia was more prevalent in the children with 25-OHD levels<18.0 ng/mL than in the children with 25-OHD levels≥18.0 ng/mL (P<0.0001). CONCLUSION: These data suggest that a vitamin D level of 18.0 ng/mL could be the criterion for 25-OHD deficiency in children at the inflection point of the maximal suppression of PTH.

The trabecular bone score (TBS) was introduced as an indirect index of trabecular microarchitecture, complementary to bone mineral density (BMD), and is derived using the same dual energy X-ray absorptiometry images. Recently, it has been approved for clinical use in Korea. Therefore, we conducted a comprehensive review to optimize the use of TBS in clinical practice. The TBS is an independent predictor of osteoporotic fractures in postmenopausal women and men aged >50 years. The TBS is potentially useful in monitoring the skeletal effects of anabolic agents but not of antiresorptive agents. In postmenopausal women with type 2 diabetes mellitus, the TBS assesses osteoporotic fracture risk not captured by BMD. However, high body mass index and soft tissue thickness can cause underestimation of the TBS; however, this limitation has been improved in recent versions of the TBS software. However, a high precision error and low reproducibility limit the use of TBS. This review may provide information on the application of the TBS in clinical practice based on reliable evidence.

OBJECTIVE: To evaluate the safety and clinical efficacy of transcatheter uterine artery embolization (UAE) for post-myomectomy hemorrhage. MATERIALS AND METHODS: We identified eight female patients (age ranged from 29 to 51 years and with a median age of 37) in two regional hospitals who suffered from post-myomectomy hemorrhage requiring UAE during the time period from 2004 to 2012. A retrospective review of the patients' clinical data, uterine artery angiographic findings, embolization details, and clinical outcomes was conducted. RESULTS: The pelvic angiography findings were as follows: hypervascular staining without bleeding focus (n = 5); active contrast extravasation from the uterine artery (n = 2); and pseudoaneurysm in the uterus (n = 1). Gelatin sponge particle was used in bilateral uterine arteries of all eight patients, acting as an empirical or therapeutic embolization agent for the various angiographic findings. N-butyl-2-cyanoacrylate was administered to the target bleeding uterine arteries in the two patients with active contrast extravasation. Technical and clinical success were achieved in all patients (100%) with bleeding cessation and no further related surgical intervention or embolization procedure was required for hemorrhage control. Uterine artery dissection occurred in one patient as a minor complication. Normal menstrual cycles were restored in all patients. CONCLUSION: Uterine artery embolization is a safe, minimally invasive, and effective management option for controlling post-myomectomy hemorrhage without the need for hysterectomy.
