ABSTRACT
Background@#Glomus tumors are benign vascular tumors derived from the glomus body, a neuromuscular vascular tissue responsible for regulating the temperature and blood flow of the skin. Ultrasonography (USG) is a useful tool for diagnosing glomus tumors; nevertheless, data on Korean patients with glomus tumors are limited. @*Objective@#This study aimed to describe USG findings of subungual glomus tumors in Korean patients. @*Methods@#We retrospectively reviewed the medical records and USG readings of 20 cases of glomus tumors in the nail apparatus diagnosed from January 2015 to December 2021. @*Results@#Twenty patients were included in this study. Four patients (20.0%) were male and 16 (80.0%) were female. The age of onset ranged from 18∼86 years, with a mean of 45.2 years. USG findings showed hypoechoic echogenicity in all cases. Tumor size ranged from 2.3∼10 mm (mean±standard deviation, 5.5±1.9 mm). The tumor shape observed on USG was oval in 16 cases (80.0%), lobulated in three cases (15.0%), and round in one case (5.0%). Tumor boundaries were well-defined in 18 cases (90.0%) and ill-defined in two cases. Posterior acoustic enhancement and cortical erosion were observed in 19 (95.0%) and 17 cases (85.0%), respectively. Increased vascularity was observed in 19 cases (95.0%). @*Conclusion@#This study revealed characteristic USG features of glomus tumors. USG is a helpful tool for the diagnosis and management of glomus tumors.
ABSTRACT
The origin of methicillin-resistant Staphylococcus aureus (MRSA) strains from otolaryngology outpatients has not been evaluated yet in Korea. We analyzed epidemiologic and genetic characteristics of MRSA isolates from the ear discharge of 64 outpatients with chronic otitis media in a Korean University Hospital during 2004. MRSA strains were grouped as either from the initial visit (n=33) or the follow-up visit (n=31) based on the timing of isolation. Healthcare-associated risk factors were frequently present among patients of the initial visit group, especially prior visit to primary clinic (79%) and antibiotic use (73%). SCCmec typing and multilocus sequence typing results showed that two genotypes, ST5-MRSA-II and ST239-MRSAIII, were prevalent in both the initial visit (73% vs. 24%) and the follow-up visit (55% vs. 42%). Pulsed-field gel electrophoresis identified eight types, including two major types shared by both groups. We conclude that majority of MRSA strains from ear discharge of chronic otitis media belonged to nosocomial clones that might be circulating in the community. This is the first report of the genetic analysis of MRSA strains from otolaryngology practices in Korea.

The so-called racemose cysticercosis, a rare variety of neurocysticercosis occurring in ventricles or basal cisterns, is characterized by abnormal growth of cystic membranes with degeneration of Taenia solium heads (scolex). Although lesions of this type are known to follow a progressive course even after ventricular shunting, there are limitations of case series treated with antiparasitic drugs, and the optimal duration of the treatment is not yet known. We report a case of relapsed racemose cysticercosis in the Sylvian fissure, who has been successfully treated with albendazole and adjunct corticosteroid for 4 weeks. The patient had been previously treated with praziquantel and ventriculoperitoneal shunt, and maintained on the anticonvulsant drug for one year, but returned to the hospital due to seizure recurrence. The patient has been well in seizure-free state for the follow-up 2 years after albendazole therapy. The subarachnoid racemose cysticercosis seems to respond well to treatment of corticosteroid along with prolonged albendazole.
