We are reporting a case of post traumatic chronic osteomyelitis of the tibia with an open wound exposing an intra medullar nail implant for 13 years. The patient presented with fresh ipsilateral tibia plateau fracture. He was treated by removal of the implant, debridement and local placement of Gentamicin impregnated PMMA beads according to guidelines of the two stage Belfast technique. After five months of wound treatment, the exposed bone was covered by healthy granulation tissue and the patient was able to fully bear weight.

Perineurial cells, which normally surround the nerve fascicles within a nerve, can be distinguished from Schwann cells by their immunoreactivity for epithelial membrane antigen (EMA) and lack of reactivity for S-100 protein. Perineurioma is a form of benign peripheral nerve sheath tumor (PNST) almost exclusively composed of perineurial cells. It is often difficult to differentiate this tumor from the other benign PNSTs or ectopic meningioma by histology alone. Immunohistochemical and electron microscopic studies are helpful for differential diagnosis. We recently experienced a case of soft tissue perineurioma in a 14-year-old girl. This tumor was presented as a 5.6 cm sized subcutaneous movable mass in the elbow. The well encapsulated soft tissue tumor consisted of spindle cells which have whorling and storiform patterns within the collagenous stroma. The spindle cells were stained positive for EMA but negative for S-100 protein, chromogranin, neuron-specific enolase or Leu-7. Ultrastructurally, they possessed long cytoplasmic processes with incomplete basal lamina, primitive intercellular junction and occasional pinocytotic vesicles.

Pelvic kidneys are anatomical abnormalities that occur when the kidney does not rise from the pelvis during embryogenesis. The majority of cases are asymptomatic, though they are associated with higher risks for traumatic injury, infections, renal calculi, and other urological issues. Because of its advantages of flexion and deflection, retrograde intrarenal surgery (RIRS) employing flexible ureterorenoscopy (fURS) is an alternative treatment method for small- to medium-sized calculi in anatomically aberrant kidneys. Presented here is a case of a 43-year-old male with a renal stone in a pelvic left kidney with the ureter crossing the midlineand is located at the prevertebral region at the level of L4 to S1.

We performed this study to examine lifestyle patterns and dietary behavior based on the level of Internet addiction of Korean adolescents. Data were collected from 853 Korean junior high school students. The level of Internet addiction was determined based on the Korean Internet addiction self-scale short form for youth, and students were classified as high-risk Internet users, potential-risk Internet users, and no risk Internet users. The associations between the students' levels of Internet addiction and lifestyle patterns and dietary behavior were analyzed using a chi-square test. Irregular bedtimes and the use of alcohol and tobacco were higher in high-risk Internet users than no risk Internet users. Moreover, in high-risk Internet users, irregular dietary behavior due to the loss of appetite, a high frequency of skipping meals, and snacking might cause imbalances in nutritional intake. Diet quality in high-risk Internet users was also worse than in potential-risk Internet users and no risk Internet users. We demonstrated in this study that high-risk Internet users have inappropriate dietary behavior and poor diet quality, which could result in stunted growth and development. Therefore, nutrition education targeting high-risk Internet users should be conducted to ensure proper growth and development.

Prevalence of childhood obesity is increasing significantly worldwide due to energy imbalance perhaps stemming from undesirable dietary behavior and physical activity level. The objective of the study was to examine the effects of physical activity level on nutritional status in elementary school students. The subjects were comprised of 287 elementary school students between 4th and 6th grades in Seoul, Korea. The level of physical activity was scored with a modified Godin leisure-time exercise questionnaire and was categorized as active, moderately active, and sedentary. Dietary intakes were obtained using a 24-hour food recall method. An analysis of variance (ANOVA) was conducted to test for global significant differences of nutrient intakes by physical activity level. Boys were more active than girls. Daily intakes of energy in moderately active boys were significantly higher than in the sedentary group, but intakes of calcium and iron in moderately active boys were lower than active boys. For girls, physical activity level did not affect nutrient density at all. Intakes of calcium, vitamin C, and folate for both boys and girls were below 50% of recommended intake. Physical activity did not affect nutrient density and our participants were exposed to nutritional imbalance. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.

We report a very rare case of atypical granular cell tumor arising in the neurohypophysis of a 56-year-old woman. The tumor was seen on radiology to be lobulated, soft and diffusely enhanced, the same as pituitary macroadenoma, but it was anatomically localized within the posterior part of the hypophysis. We partially removed the tumor via the transsphenoidal approach. The pathology showed nuclear pleomorphism, spindling features, and lymphoplasmacytic infiltration. Ki-67 and S-100 protein were focally positive in tumor cells. Histological diagnosis confirmed an atypical granular cell tumor in the sellar region, which is a rare tumor that often has the clinical appearance of a pituitary adenoma. Ophthalmologic symptoms are the most common, followed by endocrinologic manifestations. Here we describe its symptoms and radiological and pathological features.

Purpose: Patients with respiratory failure associated with neurological dysfunction often require mechanical ventilator support, which poses increased economic burden and ventilator-associated complications. A diaphragm pacing system (DPS) is an implanted device that provides respiratory support for such patients. In this systematic review, we reviewed the literature to assess the safety and efficacy of DPS for patients with respiratory failure resulting from amyotrophic lateral sclerosis (ALS) or cervical spinal cord injuries. Materials and Methods: The following databases were searched from July 10 to July 30, 2018: MEDLINE, EMBASE, Cochran library, KoreaMed, Research Information Sharing Service, Korean studies Information Service System, Korea Institute of Science and Technology Information, and Korean Medical database. The abstracts and full texts of the searched articles were reviewed by two reviewers. Results: The search keywords generated 197 articles: two randomized controlled trials, two case-control studies, and one case report involving patients with ALS; one cohort study, one case-control study, and two case reports involving patients with cervical spine injury; and one case report involving patients with both conditions were included. The primary outcome was safety profile (complications and adverse event) and efficacy (overall survival and sleep improvement). Complications and adverse events were more common in patients with ALS and spinal cord injury receiving DPS than in controls. Efficacy outcomes were inconsistent across ALS studies. Conclusion Based on safety and efficacy results, we do not support using DPS to manage respiratory failure in patients with ALS or cervical spine injury.

Background: Few studies have investigated the association between religion and health behaviors in Korea, where various religions coexist. The present study aimed to investigate the association between religion and health behaviors among primary care patients in Korea. Methods: We analyzed data from the Family Cohort Study in Primary Care. Among the 1,040 participants in the cohort, 973 of those who had reported their religion were included in the analysis. Participants completed standardized questionnaires that included religious status and lifestyle factors, such as physical activity, smoking status, drinking status, and dietary habits. The association between religion and health behaviors was analyzed using multivariate logistic regression models. Results: Among the 973 participants, 345 (35.5%) were Christian, 153 (15.7%) were Roman Catholic, 308 (31.7%) were Buddhist, and 163 (16.8%) did not have any religion. Compared with those without a religion, the odds ratio (OR) for vigorous physical activity (OR, 1.52; 95% confidence interval [CI], 1.01–2.28) increased, and that for binge drinking (OR, 0.67; 95% CI, 0.46–0.78) and problematic drinking (OR, 0.59; 95% CI, 0.35–0.99) decreased among participants with a religion. Compared with those without a religion, Catholics were more likely to engage in vigorous physical activity (OR, 2.20; 95% CI, 1.31–3.67), whereas Christians were less likely to engage in heavy (OR, 0.50; 95% CI, 0.30–0.84), binge (OR, 0.35; 95% CI, 0.22–0.54), and problematic drinking (OR, 0.46; 95% CI, 0.25–0.86). Smoking, meal regularity, and breakfast consumption were not associated with religion. Conclusion The status of drinking and physical activities were different according to religion. As religion is one of the psychosocial characteristics of patients, knowing patients’ religion can be helpful for primary physicians.

Background: Dual-type calcium channel blockers (CCBs), such as efonidipine and cilnidipine, are renoprotective drugs that reportedly reduce proteinuria by dilating afferent and efferent arterioles of the glomerulus. However, studies comparing the effect of dual-type CCB on proteinuria have not been conducted. Therefore, we aimed to compare the effect of dual-type CCB (efonidipine and cilnidipine) usage patterns in hypertensive patients with chronic kidney disease (CKD). Methods: This single-center, retrospective study included 53 patients with CKD who 1) initiated efonidipine or cilnidipine treatment while on a renin-angiotensin system inhibitor and 2) had received efonidipine or cilnidipine for at least one year. We compared usage patterns between the efonidipine and cilnidipine groups during the one-year period and analyzed the following outcomes: urinary protein-to-creatinine ratio, blood pressure, and serum creatinine. Results: The study included 25 patients in the efonidipine group and 28 patients in the cilnidipine group. In both groups, blood pressure and urinary protein-to-creatinine ratios tended to decrease; however, the change during each interval was not significant. Conclusions In patients with CKD who were on renin-angiotensin system inhibitor therapy, the addition of a dual-type CCB (i.e., efonidipine or cilnidipine) tended to reduce proteinuria; however, the change during each interval was not significant.
