Joint contracture in chronic graft-versus-host disease (cGVHD) is refractory to treatment, and tends to deteriorate gradually over time. There is scant clinical research focusing on timing and intensity of rehabilitation on joint contractures in children with sclerodermoid cGVHD after hematopoietic stem cell transplantation. We retrospectively reviewed rehabilitative therapeutic effects in 6 children with sclerodermoid cGVHD, whose clinical records documented their condition, before and after rehabilitation therapies. Three children who started treatment within a mean of 2 months after the onset of joint symptoms, and who underwent home-based exercise twice daily for 30 minutes showed more prominent improvement in range of motion compared with the other 3 children, who started rehabilitation therapy later than 6 months after onset of joint symptoms, without regular home-based exercise.

OBJECTIVE: To identify the relationship between maximum phonation time (MPT) and swallowing function, as well as the elements of swallowing, in order to provide a rationale for speech therapy in patients with Parkinsonism manifesting dysphagia. METHODS: Thirty patients with Parkinsonism who underwent speech evaluation and videofluoroscopic swallowing study (VFSS) were recruited. The MPT, the longest periods of sustained pronunciation of /aa/, was evaluated. The VFSS was evaluated using Penetration Aspiration Scale (PAS), National Institutes of Health-Swallowing Safety Scale (NIH-SSS), and Videofluoroscopic Dysphagia Scale (VDS). The relationship between dysphagia scales and MPT was analyzed using Pearson correlation. The difference in VDS variables between subgroups (Parkinson disease or Parkinsonian syndrome, independent or dependent ambulation, and normal or abnormal MPT) and the difference in MPT between subgroups based on the VDS variables were analyzed using the independent t-test. RESULTS: Bolus formation and laryngeal elevation functions were significantly higher in the normal MPT group compared with the impaired group. In the VDS variables, patients with intact bolus formation, oral transit time, pharyngeal swallow triggering, and laryngeal elevation showed significantly longer MPTs compared with the impaired groups. In addition, MPT was significantly correlated with the VDS and modestly correlated with the NIH-SSS, but not the PAS, suggesting that phonatory function is related to the oropharyngeal swallowing function, but not directly to the aspiration itself. CONCLUSION: The correlation between MPT and several swallowing-related elements was identified, indicating an interactive correlation between swallowing and phonation. This result justifies voice therapy as a treatment for dysphagia in patients with Parkinsonism.

OBJECTIVE: To investigate the neurodevelopmental outcomes in children with developmental disorder according to visual evoked potential (VEP) results. METHODS: We retrospectively analyzed children who visited our Department of Pediatric Rehabilitation Medicine with a chief complaint of developmental disability from January 2001 to July 2015. Of the 549 medical records reviewed, 322 children younger than 42 months who underwent both Bayley Scales of Infant and Toddler Development second edition (BSID-II) and VEP studies were enrolled. We compared the development of 182 children with normal VEP latency and 140 children with delayed VEP latency results using the BSID-II results. The Mann-Whitney U-test was used to analyze the differences between the two groups. RESULTS: There were no significant differences in baseline characteristics between the two groups. The delayed VEP latency group showed a significant delay in BSID-II index scores and developmental quotients compared with the normal VEP latency group. In addition, a comparative analysis of developmental quotients of mental and psychomotor domains according to age (younger than 12 months, 12–23 months, and 24–42 months) revealed significantly lower values in children with delayed VEP latency compared to children with normal VEP latency, younger than 12 months and from 12 to 23 months. CONCLUSION: Children with delayed VEP latency showed more developmental delay than children with normal VEP latency. It is suggested that VEP can be easily applied to children with suspected developmental delay when physicians have concerns about visual impairment. Furthermore, it is proposed that VEP results could provide an insight into children's development and serve as early indicators for consultation with an ophthalmologist for the existing problem.

The transient receptor potential canonical (TRPC) 5 channel, known as a nonselective cation channel, has a crucial role in calcium influx. TRPC5 has been reported to be activated by muscarinic receptor activation and extracellular pH change and inhibited by the protein kinase C pathway. Recent studies have also suggested that TRPC5 is extracellularly activated by englerin A (EA), but the mechanism remains unclear. The purpose of this study is to identify the EA-interaction sites in TRPC5 and thereby clarify the mechanism of TRPC5 activation. TRPC5 channels are over-expressed in human embryonic kidney (HEK293) cells. TRPC5 mutants were generated by site-directed mutagenesis. The whole-cell patch-clamp configuration was used to record TRPC5 currents. Western analysis was also performed to observe the expression of TRPC5 mutants. To identify the EA-interaction site in TRPC5, we first generated pore mutants. When screening the mutants with EA, we observed the EA-induced current increases of TRPC5 abolished in K554N, H594N, and E598Q mutants. The current increases of other mutants were reduced in different levels. We also examined the functional intactness of the mutants that had no effect by EA with TRPC5 agonists, such as carbachol or GTPγS. Our results suggest that the three residues, Lys-554, His-594, and Glu-598, in TRPC5 might be responsible for direct interaction with EA, inducing the channel activation. We also suggest that although other pore residues are not critical, they could partly contribute to the EA-induced channel activation.

Objectives: We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea. Methods: We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sexspecific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level. Results: During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women. Conclusions Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.

Objective: In this video, we present our novel technique for myometrial defect closure following robot-assisted laparoscopic adenomyomectomy. Methods: A narrated video demonstration of our technique. Our patient was a 47-year-old single woman with severe dysmenorrhea, who did not respond to medical therapy and wished to preserve her uterus. Surgery was performed after thorough counseling and obtaining informed consent from the patient (Institutional Review Board number: KC17OESI0238; approval date: March 19, 2018). After removal of the adenomyotic tissue during surgical intervention, the myometrial defect was closed in three steps. First, the defect between the anterior and posterior innermost myometrial layers was closed using a 2-0 Stratafix suture, CT-1 (circle taper) needle (Ethicon, Somerville, NJ, USA). Next, the two sides were approximated using a 2-0 PDS® (polydioxanone) Suture (Ethicon, Somerville, NJ, USA) and V-34 (TAPERCUT®) surgical needle (Ethicon, Somerville, NJ, USA). Finally, the serosa was sutured in a baseball fashion using a 2-0 PDS suture, slim half-circle [SH] needle (Ethicon, Somerville, NJ, USA). Results: The patient had no postoperative complications, and her pain was greatly improved. The CA125 level decreased from 434 U/mL to 45.99 U/mL, and the transvaginal ultrasound showed a reduction in posterior myometrial thickness from 5.61 cm to 2.69 cm. Conclusion This technique maintained the integrity of the endometrial cavity, posterior myometrial thickness, and uterine layer alignment. We believe that it is a feasible technique and may be a solution for adenomyosis in patients seeking for fertility preservation.

Objectives: The aim of this study is to determine whether there is a difference between right and left femur bone mineral density (BMD) in postmenopausal women. Methods: We performed a retrospective chart review of postmenopausal women who underwent bone mineral density (BMD) measurement from 2010 to 2019 at a single center using dual-energy X-ray absorptiometry (DXA). Data, including BMD and T-scores of bilateral hip and lumbar spine, was gathered for all postmenopausal women above the age of 50 years. The continuous variables were expressed as means with standard deviation for normal distribution and analyzed with a two-sample t-test. Multiple regression analysis was used to test the effect of underlying medical conditions on T-score of bilateral hips. For all analyses, a p-value of ＜0.05 was considered significant. Results: 346 patients were included in the study with a mean age at imaging of 62 + 9.7 years and body mass index (BMI) of 23.4 + 6.1 kg/m2 . There were no significant differences between right and left femoral BMDs in all patients. There were significant differences in BMD of both total femurs in women in their 60s and women with normal BMD. There was no difference in both femur BMDs between those taking hormone therapy and those not taking hormone therapy. In patients undergoing osteoporosis treatment, there was a difference in the BMD of both femur neck. Calcium and vitamin D intake were not associated with differences between both femur BMD. We found a significant correlation between the BMD measures at lumbar spine and both femur (p ＜ 0.01). Conclusion There were no significant differences between right and left femoral BMDs in postmenopausal women. Therefore, BMD may be measured at either hip. The correlation of bone density between lumbar spine and femur neck is shown to be statistically meaningful. Based on the knowledge of the correlation coefficients between lumbar spine and femur neck, it seems possible to predict the BMD result of one location through the measurement of another.
