Purpose: This study aimed to determine the urodynamic characteristics of refractory enuresis and explored whether those characteristics can be managed through differential endoscopic injections with botulinum toxin. Methods: In total, 27 patients with nonmonosymptomatic enuresis who showed no response after conservative treatment for more than 12 months were included. The patients then underwent a videourodynamic study and received a differential endoscopic injection of botulinum toxin on the same day. Reduced capacity, detrusor overactivity, and bladder neck widening were the 3 major abnormal findings assessed during the filling phase, while sphincter hyperactivity was the only abnormality assessed during the emptying phase. An intravesical or intrasphincteric injection of botulinum toxin was attempted according to the videourodynamic study findings. Follow-up was conducted at 1, 3, 6, and 12 months after treatment. Results: The median age was 10 years (range, 7–31 years). Although 19 and 8 patients had a preoperative diagnosis of overactive bladder or dysfunctional voiding, respectively, the urodynamic diagnosis was different in more than half of the patients. Those showing detrusor overactivity benefited from intravesical botulinum toxin injection, whereas those with only sphincter hyperactivity benefited from both intravesical and intrasphincteric injections. Treatment resistance to botulinum toxin seemed to be attributable to bladder neck widening. Time had no apparent effect on efficacy, which persisted 6 months after the injection. More than 80% of the patients maintained the benefits of the injection after 1 year. Conclusions Videourodynamic studies were useful for identifying the reasons underlying refractory nonmonosymptomatic enuresis and helpful for determining the appropriate site of botulinum toxin injection.

Background: The clinical features of pediatric rhabdomyolysis differ from those of the adults with rhabdomyolysis; however, multicenter studies are lacking. This study aimed to investigate the characteristics of pediatric rhabdomyolysis and reveal the risk factors for acute kidney injury (AKI) in such cases. Methods: This retrospective study analyzed the medical records of children and adolescents diagnosed with rhabdomyolysis at 23 hospitals in South Korea between January 2007 and December 2016. Results: Among 880 patients, those aged 3 to 5 years old composed the largest subgroup (19.4%), and all age subgroups were predominantly male. The incidence of AKI was 11.3%. Neurological disorders (53%) and infection (44%) were the most common underlying disorder and cause of rhabdomyolysis, respectively. The median age at diagnosis in the AKI subgroup was older than that in the non-AKI subgroup (12.2 years vs. 8.0 years). There were no significant differences in body mass index, myalgia, dark-colored urine, or the number of causal factors between the two AKI-status subgroups. The multivariate logistic regression model indicated that the following factors were independently associated with AKI: multiorgan failure, presence of an underlying disorder, strong positive urine occult blood, increased aspartate aminotransferase and uric acid levels, and reduced calcium levels. Conclusions Our study revealed characteristic clinical and laboratory features of rhabdomyolysis in a Korean pediatric population and highlighted the risk factors for AKI in these cases. Our findings will contribute to a greater understanding of pediatric rhabdomyolysis and may enable early intervention against rhabdomyolysis-induced AKI.

Purpose: Quality of life (QOL) has become important in the trend of emphasizing patient satisfaction. This study aimed to evaluate the QOL in patients who underwent laparoscopic or robotic gastrectomy for gastric cancer. Methods: A prospective trial was performed involving patients who underwent laparoscopic or robotic gastrectomy for primary gastric cancer at 11 hospitals in Korea. Within this comparative trial, QOL, postoperative pain, and long-term complications were exanimated. The quality-of-life questionnaire (QLQ)-C30 and QLQ-STO22 developed by the European Organization for Research and Treatment of Cancer were used for the QOL survey. We compared the data after dividing it into several types of characteristics as follows; device (robotic or laparoscopic), operation type, pathological stage, and sex.Biased components were extracted by logistic regression analysis. Propensity score matching was applied to the data set with the biased components. Results: In total, 434 patients (211 for laparoscopic surgery and 223 for robotic surgery) were enrolled, out of which 321 patients who responded to both preoperative and postoperative surveys were selected for analysis. Robotic gastrectomy was not different from laparoscopic gastrectomy with respect to postoperative QOL. Distal gastrectomy showed better scores than total gastrectomy in terms of role functioning, social functioning, fatigue, nausea/vomiting, pain, dyspnea, constipation, financial difficulties, dysphagia, eating restrictions, anxiety, taste, and body image. Male patients showed better scores on the 19 scales compared to female patients. Conclusion Robotic and laparoscopic approaches for gastric cancer surgery did not differ from each other with respect to QOL. Distal gastrectomy resulted in better QOL than total gastrectomy.

Soft liner is used to functional impression technique when dental stone is immediately poured after taking impression because of viscoelasticity. In this case, a 78-year-old male visited for new dentures. Due to severe resorption of mandibular edentulous ridge, functional impression taking by closed mouth technique was planned. First of all, making maxillary and mandibular provisional dentures was done, and lined by soft liner to rehabilitate pressured maxillary and mandibular edentulous ridge. After this, Functional impression was taken by closed mouth technique using provisional dentures which are transformed to healed maxillary and mandibular edentulous ridge, and final denture were fabricated using maxillary provisional denture as a reference of artificial teeth arrangement. Consequently, restoring a complete edentulous patient with taking functional impression using provisional dentures resulted in recovering satisfying retention and function.

OBJECTIVE: This study aimed to assess the association between bone mineral density (BMD) and coronary atherosclerosis in healthy postmenopausal women. METHODS: We performed a retrospective review of 252 postmenopausal women who had visited a health promotion center for a routine checkup. BMD of the lumbar spine (L1-L4) and femoral neck was evaluated using dual-energy X-ray absorptiometry, and coronary atherosclerosis was assessed using 64-row multidetector computed tomography. Participants were divided into normal BMD and osteopenia-osteoporosis groups, according to the T-scores of their lumbar spine or femoral neck. RESULTS: Participants with osteopenia-osteoporosis had a significantly higher proportion of coronary atherosclerosis than did those with normal BMD at the lumbar spine (P=0.003) and femoral neck (P=0.004). Osteopenia-osteoporosis at the lumbar spine (odds ratio [OR], 2.86; 95% confidence interval [CI], 1.12 to 7.27) or femoral neck (OR, 3.35; 95% CI, 1.07 to 10.57) was associated with coronary atherosclerosis, after controlling for age and cardiovascular risk factors. CONCLUSION: Decreased BMD is associated with coronary atherosclerosis in healthy postmenopausal women, independent of age and cardiovascular risk factors. Postmenopausal women with decreased BMD may have a higher risk of developing coronary atherosclerosis.

OBJECTIVE: Neural tissue transplantation has been a promising strategy for the treatment of Parkinson's disease (PD). However, transplantation has the disadvantages of low-cell survival and/or development of dyskinesia. Transplantation of cell aggregates has the potential to overcome these problems, because the cells can extend their axons into the host brain and establish synaptic connections with host neurons. In this present study, aggregates of human brain-derived neural stem cells (HB-NSC) were transplanted into a PD animal model and compared to previous report on transplantation of single-cell suspensions. METHODS: Rats received an injection of 6-OHDA into the right medial forebrain bundle to generate the PD model and followed by injections of PBS only, or HB-NSC aggregates in PBS into the ipsilateral striatum. Behavioral tests, multitracer (2-deoxy-2-[18F]-fluoro-D-glucose ([18F]-FDG) and [18F]-N-(3-fluoropropyl)-2-carbomethoxy-3-(4-iodophenyl)nortropane ([18F]-FP-CIT) microPET scans, as well as immunohistochemical (IHC) and immunofluorescent (IF) staining were conducted to evaluate the results. RESULTS: The stepping test showed significant improvement of contralateral forelimb control in the HB-NSC group from 6-10 weeks compared to the control group (p<0.05). [18F]-FP-CIT microPET at 10 weeks posttransplantation demonstrated a significant increase in uptake in the HB-NSC group compared to pretransplantation (p<0.05). In IHC and IF staining, tyrosine hydroxylase and human beta2 microglobulin (a human cell marker) positive cells were visualized at the transplant site. CONCLUSION: These results suggest that the HB-NSC aggregates can survive in the striatum and exert therapeutic effects in a PD model by secreting dopamine.

PURPOSE: Since there are no proven tumor markers that reflect the course of gastric cancer, carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are commonly used alternatives. However, the degree of progression that corresponds to an increase in these markers, and the values of these markers at different cancer stages, remains unclear. MATERIALS AND METHODS: This study enrolled 1,733 gastric cancer patients who underwent surgery and whose pre-operative CEA and CA19-9 levels were known. Survival curves and mean values of the two markers were compared according to the degree of cancer progression: serosa-unexposed (SU), serosa-exposed (SE), direct invasion (DI), localized seeding (P1), and extensive seeding (P2). RESULTS: The 5-year overall survival rates at each stage differed significantly, except between DI and P1 patients (17.1% vs. 10.5%, P=0.344). The mean CEA values in SU, SE, DI, P1, and P2 patients were 5.80, 5.48, 13.36, 8.06, and 22.82, respectively. The CA19-9 values for these patients were 49.40, 38.97, 101.67, 73.77, and 98.57, respectively. The increase in CEA in P2 patients was statistically significant (P=0.002), and the increases in CA19-9 in DI and P2 patients were significant (P=0.025, 0.007, respectively). There was a fair correlation between the two markers in P2 patients (r=0.494, P<0.001). CONCLUSIONS: CA19-9 can be used to assess DI of gastric cancer into adjacent organs. Both markers are useful for predicting the presence of extensive peritoneal seeding.

BACKGROUND: Viridans streptococci is a major pathogen of infective endocarditis. This study was conducted in order to investigate the factors associated with infective endocarditis and predictors for three-month mortality among patients with viridans streptococcal bacteremia (VSB). MATERIALS AND METHODS: In this study, among 261 eligible patients diagnosed as VSB from January 2000 through June 2011 in a university-affiliated hospital, a retrospective analysis of 197 patients was conducted. All patients with VSB were classified into two groups according to sites of bacteremia; infective endocarditis and other infections. Demographic and clinical characteristics were reviewed through electronic medical records factors associated with infective endocarditis and predictors of three-month mortality in VSB patients were evaluated. RESULTS: Of the 197 patients, 37 (18.8%) patients had viridans streptococcal infective endocarditis (VSIE) and 160 (81.2%) patients had VSB due to other infection. In logistic regression analysis, underlying valvular heart disease (odds ratio [OR], 48.43; 95% confidence interval [CI], 5.77-406.38) and persistent bacteremia (OR, 46.32; 95% CI, 7.18-299.01) showed an independent association with VSIE. Three-month mortality rate was 21.7% in patients with VSB. In logistic regression analysis, previous steroid use (OR, 9.31; 95% CI, 1.34-64.52), previous immunosuppressive therapy (OR, 9.50; 95% CI, 2.13-42.30), hypotension at onset of bacteremia (OR, 7.72, 95% CI, 2.45-24.33), and Charlson comorbidity score > or =3 (OR, 4.53, 95% CI, 1.55-13.28) showed an independent association with three-month mortality in patients with VSB. CONCLUSIONS: VSB patients who have valvular heart disease or persistent bacteremia routinely require echocardiography. Previous steroid use, immunosuppressive therapy, hypotension, and higher Charlson comorbidity score suggested poor prognosis in patients with VSB.

BACKGROUND: Environmental pollutants are thought to be one of major triggers of atopic dermatitis (AD). OBJECTIVE: We attempted to evaluate the clinical effects of environment with low indoor pollutant levels on AD management. METHODS: Fifty-one children (mean age 1.7 years) with moderate to severe AD who failed to show improvement with conventional management were recruited. Disease severity was assessed by SCORAD (Scoring of AD) indices. They were admitted in a low pollutant oom for 3-4 days (mean 3.3 days) which was designed to keep low levels of dust, house dust mites, micro-organisms, and indoor air pollutants such as total volatile organic compounds (TVOCs), particulate matter (PM), and so on. Air pollutant levels in the low pollutant room were lower than primary standards defined by the Korean Ministry of Environment. we compared disease severity on admission and after discharge, and the pollutant levels of each patient's home and low pollutant room. RESULTS: The SCORAD was significantly reduced from 42.0 ± 11 .5 to 29.8 ± 8.9 (p < 0.001) by management in a low pollutant room. PM₂.₅, PM₁₀, formaldehyde, TVOCs, carbon dioxide, bacterial suspensions, and indoor molds were significantly higher in the patient's home than low pollutant room. Out of 29 patients who deteriorated after discharge to their home, 8 patients were admitted again, and their SCORAD was rapidly decreased from 53.1 ± 16.2 to 39.2 ± 9.8 (p = 0.036). CONCLUSION: Indoor air pollutants are likely to affect AD in susceptible individuals. Environmental control to lower indoor air pollutant levels might be necessary for better management of AD in some patients.
