Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.

Various types of tumor can occur in the subungual space, including glomus tumors, subungual exostosis, hemangioma, epidermal cysts, and malignant tumors. While fibromatosis can occur at various sites throughout the body, it is very rarely seen in the toe. Here, we are the first to report a case of superficial fibromatosis mimicking a glomus tumor in the subungual space of the second toe. The presentation of this condition shows the possibility of encountering uncommon superficial fibromatosis in the distal phalanx of the toe, and suggests that superficial fibromatosis should be included in the differential diagnosis of a glomus tumor in the toe.

PURPOSE: TATA box mutation/polymorphism in the promoter region of the bilirubin uridinediphosphoglucuronate glucuronosyltransferase 1A1 (UGT-1A1) gene is known to be an etiology of hyperbilirubinemia. This study examined if a TATA box mutation/polymorphism in UGT-1A1 gene promoter could be associated with the development of severe early neonatal jaundice in Korean infants. METHODS: Thirty-nine neonatal jaundice patients and 40 controlled infants were analyzed for UGT-1A1 promoter genotypes by using DNA sequencing. RESULTS: The homozygote for (TA)7TAA mutation was not found in this study. Comparison of the prevalence of UGT-1A1 promoter (TA)7TAA heterozygotes revealed no difference between the group with jaundice and the controlled group (15.4% vs. 10%). The peak bilirubin level was higher and the onset of jaundice was earlier in the jaundice group with (TA)7TAA heterozygote compared to the jaundice group without (TA)7TAA heterozygote (23.2+/-1.0 mg/dL vs. 19.7+/-2.4 mg/dL, P=0.004, 5.0+/-1.5 days vs. 8.3+/-4.1 days, P= 0.057). CONCLUSION: The results of this study showed that TATA box polymorphism in UGT-1A1 gene promoter did not increase the prevalence of severe early neonatal jaundice in Korean infants.

This article describes a case of intra-abdominal desmoplastic small round cell tumor(DSRCT) experienced by the authors. The patient was 36ear old male, and admitted because of the mass of right inguinal area, back pain, weakness of low extremities. Imaging studies, right inguinal mass biopsy finding, immunohistochemical stains were compatible with DSRCT. Aggressive treatment with chemotherapy resulted in remarkable response temporarily in terms of tumor size and pulmonary metastasis. But as other author`s reports, multiple metastases to brain, spine, lung were progressed in our case. The patient died 13months after diagnosis.

A number of complications during the use of double-lumen endobronchial tubes are reported, specifically tracheobronchial rupture, a rare but serious complication. Risk factors associated with tracheobronchial rupture include inexperienced endoscopists, intubating stylets, multiple vigorous attempts at intubation, overdistension of the tracheal or bronchial cuff with high pressure, position change with an inflated cuff, and anatomical abnormality. We report 2 cases of tracheobronchial rupture which occurred during the use of double-lumen endobronchial tubes.

Fibromuscular dysplasia (FMD) is a rare, segmental nonatheromatous angiopathy of unknown etiology affecting small to medium-sized arteries. The most common angiographic pattern is the classic string-of-beads appearance. But the tubular stenosis type of the FMD is a rare finding and has not been reported previously. We report a case who presented with recurrent intracerebral hemorrhages, whose angiographic features were long tubular stenosis type of FMD affecting the both internal carotid arteries associated with terminal carotid occlusions.

PURPOSE: To evaluate the usefulness of post-enhanced delayed FLAIR (fluid-attenuated inversion-recovery) images in the diagnosis of leptomeningitis. MATERIALS AND METHODS: We obtained the pre- and post-enhanced FLAIR images of 7 rabbits every hour after infusing triple doses of contrast, and we measured the signal intensities of the CSF (cerebrospinal fluid) and the brain parenchyma. Five leptomeningitis patients and 5 volunteers were enrolled to obtain the pre-enhanced FLAIR images, the early post-enhanced FLAIR images and the delayed post-enhanced FLAIR images, with using a standard dose of contrast, and to measure the signal intensities of the CSF and brain parenchyma. The statistical significances were determined by a mixed procedure and the Wilcoxon rank-sum test (p<0.05). RESULTS: In the rabbits, the signal intensities of the CSF began to increase after an hour of contrast infusion, but those of the parenchyma did not increase. The time of maximum CSF enhancement was 2 hours after contrast infusion (p<0.001; standard estimate=750.43) and we obtained the post-enhanced delayed FLAIR images for clinical studies according to this result. The signal intensities of the CSF in the subarachnoid space were higher in the patient group compared with those of the normal control group on both the early post-enhanced FLAIR images and the delayed post-enhanced FLAIR images (p=0.0096) (p=0.0391). In the patient group, changes of signal intensities of the CSF in the subarachnoid space were more conspicuous on the delayed post-enhanced FLAIR images than on the early post-enhanced FLAIR images (p=0.0042). However, those of the parenchyma were not different in either group. CONCLUSION: The post-enhanced delayed FLAIR images obtained at 2 hours after contrast infusion are more useful for making the the diagnosis of leptomeningitis than are the post-enhanced early FLAIR images.

Although enhanced appetite and weight gain are potential side effects of treatment with antipsychotic agents, particularly olanzapine and clozapine, the mechanisms underlying these side effects are poorly understood. Leptin and ghrelin were recently identified as hormones that play crucial roles in the regulation of energy balance and glucose metabolism. To elucidate relationships between weight change and plasma levels of ghrelin and leptin, we investigated the circulating ghrelin and leptin levels and body weight during olanzapine treatment. Twenty-four patients with schizophrenia were examined during 6-month administration of olanzapine. Ghrelin, leptin, weight and body mass index (BMI) were measured before and after 2, 4, 8, 12, 16, and 24 weeks of olanzapine treatment. The concentration of glucose and various lipid metabolic parameters were measured at baseline and at 24 weeks. Significant increases in weight, BMI and leptin were observed at week 24. On the other hand, the serum levels of ghrelin decreased significantly after olanzapine treatment. In addition, the level of ghrelin was negatively correlated with the leptin level, BMI and weight. The leptin level was positively correlated with both BMI and weight. Ghrelin is associated with metabolic changes, in combination with leptin, during olanzapine treatment. However, further large-scale and longitudinal studies are warranted to elucidate the metabolic changes involving ghrelin, leptin and insulin during treatment with antipsychotics.

BACKGROUND AND OBJECTIVES: Although many studies have assessed factors related to adherence of PAP therapy, there were no studies about factors related to doctors or device managers. The purpose of this study was to investigate the relationship between PAP therapy adherence and doctor or device manager. SUBJECTS AND METHODS: Between February 2013 and June 2015, 163 patients newly diagnosed with moderate to severe OSA in one of five hospitals were enrolled in this study. All patients received 4 weeks of PAP treatment with intervention consisting of mechanical support and motivation by doctor and device manager. Data from the PAP device were obtained following a minimum of an initial 30 days, with adherence defined as >4 h/night on 70% of nights. RESULTS: After 30 days, total adherence rate to PAP therapy was 35.6% (n=58). The adherence rate of device manager ① was 26.3% (31/118), and that of device manager ② was 60% (27/45), and there was statistically significant difference between the two device managers. Furthermore, there were statistically significant differences in the adherence to PAP therapy ranging from 85.6% to 0.0% according to doctor. CONCLUSION: Our study demonstrates that the device manager and doctor may be important factors for good adherence to PAP therapy in patients with OSA.

In children, prolonged primary Epstein-Barr virus (EBV) infection or reactivation may lead to the development of T or natural killer cell lymphoproliferative disorders, classified as chronic active EBV infection (CAEBV). CAEBV is a prolonged systemic illness lasting beyond three months, with elevated EBV DNA levels in the serum or affected tissue and a lack of underlying immunodeficiency. Notably, EBV is the most common virus that induces secondary hemophagocytic lymphohistiocytosis (HLH), and Coronavirus disease 2019 (COVID-19) has been reported to trigger HLH. We present the case of a 20-year-old Korean male who was diagnosed with CAEBV and developed HLH after being infected with COVID-19. The patient met 7 out of 8 criteria for HLH. Following treatment with corticosteroids and intravenous immunoglobulin, the patient recovered from HLH without additional chemotherapy. HLH treatment should be tailored to each patient based on clinical presentation and disease severity.Prolonged and regular evaluation for developing HLH or lymphoma is necessary for patients with CAEBV.
