Background and Objectives: Little is known about studies evaluating positive airway pressure (PAP) compliance after re-prescription. Therefore, the aim of this study was to investigate PAP compliance after re-prescription in obstructive sleep apnea (OSA) patients who failed initial PAP therapy. Methods: We retrospectively reviewed OSA patients who had received a re-prescription for PAP from March 2020 to June 2021. We compared the compliance rate between initial prescription and re-prescription for PAP and investigated the reasons for PAP failure after the first prescription. Results: A total of 10 consecutive OSA patients (mean age=45.6±13.7 years and male:female=8:2) who received a re-prescription for PAP were included. Of them, 8 patients (80%) met the compliance criteria (i.e., Korean National Health Insurance criteria) for PAP after re-prescription. The compliance rate increased from 36.3±18.2% (initial prescription) to 61.3±28.8% (re-prescription); this was not of statistical significance (p=0.074). PAP/mask-related discomfort was the most common reason for PAP failure, followed by nasal obstruction, unintentional mask removal, and pressure-related discomfort. Conclusion Even if initial PAP therapy fails, the proportion of patients who meet the compliance criteria may be improved through various forms of clinical aid and support after re-prescription of PAP.

Foreign body ingestion is a common problem in the pediatric population and the majority of such cases occur between the ages of six months and three years. Most objects pass uneventfully through the gastrointestinal tract; however, ingestion of multiple magnets can cause serious gastrointestinal complications through interaction with each other across the bowel wall. In these situations, radiologic evaluation is imperative for proper treatment. This is a case report on ingestion of 32 magnets in a 10-year-old boy. We diagnosed a small bowel fistula caused by ingestion of multiple magnets using sonography, which showed hyperechoic magnetic foreign bodies attached together penetrating the thickened neighbouring jejunum.

This study was aimed to evaluate the prophylactic anti-glaucoma effect of topical 5% betaxolol (BTX) and 2% dorzolamide (DRZ) on the second eye in dogs with unilateral primary angle closure glaucoma (PACG). Medical records of 60 dogs with unilateral PACG who received prophylactic anti-glaucoma eyedrops in the second eye, from 2016 to 2021, were reviewed. The duration of prophylactic effects of BTX only and DRZ after BTX failure was calculated. The prophylactic effects of BTX were maintained on 28/60 (46.7%) eyes until last visit and BTX failure was observed on median 510 (range, 53-1,927) days in 32/60 (53.3%) eyes. After DRZ instillation in BTX failure eyes, the prophylactic effects were extended at median 610 (range, 157-2,270) days in 21/32 (65.6%) eyes. DRZ failure eyes (17/21, 81.0%) eyes required chemical ablation or surgical intervention due to uncontrolled intraocular pressure. The duration of prophylactic effects was decreased with aging (R² = 0.334, p = 0.006). The predominant breeds were Shih-Tzu (41.9%) and American Cocker Spaniel (30.6%) with no significant differences in survival curves (p = 0.210). The average prophylactic effects of BTX persisted more than 1.5 year and could be selected the first prophylactic eye drop in unilateral PACG. Also, early surgical intervention should be considered in prophylactic medications failure cases.

The complement system is a part of the innate immune system that potentiates the ability of antibodies and phagocytic cells to clear microbes and damaged cells. The complement system consists of a number of proteins circulating as inactive precursors. It is stimulated mainly by three pathways: the classical pathway, the alternative pathway, and the lectin pathway. There are many genetic polymorphisms in this system, which can over-activate the immune system. In this study, we collected the polymorphisms reported to over-activate complement cascades that affect the immune system and induce autoimmune diseases.

Primary epiploic appendagitis (PEA) is a condition that results from spontaneous torsion, ischemia, or inflammation of an epiploic appendage. This condition is manifested by localized abdominal pain and tenderness, which is often mistaken for diverticulitis or appendicitis in the adult population. PEA is a self-limiting disease, and differential diagnosis with surgical condition is important in order to prevent unnecessary surgery. Although it is commonly reported in adults, it is rarely reported in the pediatric population. We report on the radiologic findings of two cases of PEA in a 12- and a 17-year-old boy, focusing on sonographic findings.

Objectives: Selection of treatment methods for mandibular condylar fractures remains controversial. In this study, we investigated treatment methods for condylar fractures to determine the indications for open or closed reduction. Patients and Methods: Patients >12 years of age treated for mandibular condylar fractures with a follow-up period of ≥3 months were included inthis study. The medical records of enrolled patients were reviewed for sex, age, fracture site, treatment method (open or closed reconstruction), postoperative intermaxillary fixation period, operation time, and complications. Radiological analysis of fracture fragment displacement and changes in ramal height difference was performed using computed tomography and panoramic radiography. Results: A total of 198 patients was investigated, 48.0% (n=95) of whom underwent closed reduction and 52.0% (n=103) underwent open reduction.There was no significant correlation between reduction method and patient sex, age, or follow-up period. No statistically significant difference between the incidence of complications and treatment method was observed. None of the patients underwent open reduction of condylar head fracture. Binary logistic regression analysis showed that open reduction was significantly more frequent in patients with subcondylar fracture compared to in those with a fracture in the condylar head area. There was no statistically significant correlation between the groups and fracture fragment displacement. However, there was a significant difference between the treatment groups in amount of change in ramal height difference between the fractured and the nonfractured sides during treatment. Conclusion No significant clinical differences were found between the open and closed reduction methods in patients with mandibular condylar fractures. According to fracture site, closed reduction was preferred for condyle head fractures. There was no significant relationship between fracture fragment displacement and treatment method.
