A teratoma is a neoplasm that contains tissues originating from three germ cell layers at ectopic sites. The embryology of teratomas remains unclear. Teratomas are usually composed of cystic and solid components, and they are usually associated with syringomyelia. Cystic lesions of teratomas may rupture in a spontaneous, iatrogenic, or traumatic manner. Lipid droplets in the ventricles and subarachnoid space are rare. We managed a case of a spinal teratoma in the lumbar region in a 67-year-old man. He complained of nocturia, frequent urination, and difficulty in walking for 2 months. Radiographic imaging revealed a lumbar spinal intradural mass. Intracranial lipid droplets dissemination was also existed. The patient underwent surgery, and a diagnosis of mature teratoma was confirmed histopathologically. During the operation, the cystic portion of the intradural mass ruptured. During the hospital stay, the patient's mental status declined. On radiological examination, slightly enlarged ventricle size was observed. Dissemination of lipid droplets within ventricles occurs because of spontaneous, iatrogenic, or traumatic rupture. Additional lipid droplet dissemination to the intracranial space associated with neurologic deterioration after a spinal teratoma surgery should be considered when iatrogenic rupture of the cyst portion occurs.

PURPOSE : JAK kinases play important roles not only in normal cellular processes, but they are also important in tumor development. A recent study identified two somatic mutations of JAK1 in leukemia cells that were detected in exon 10 (p.T478S) and exon 13 (p.V623A). The aim of this study was to see whether the JAK1 mutations in these exons occur in non-small cell lung cancers (NSCLC). MATERIALS AND METHODS : We analyzed the exons 10 and 13 of JAK1 for detecting somatic mutations in NSCLC by performing polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) assay. RESULTS : The SSCP analysis revealed no evidence of somatic mutation in the DNA sequences of JAK1 exon 10 and exon 13 in the 47 NSCLCs. CONCLUSION : The data presented here indicate that the JAK1 exons 10 and 13 may not be somatically mutated in human NSCLCs, and this suggests that the JAK1 mutation in exons 10 and 13 may not play an important role in the tumorigenesis of NSCLCs

Clinical practice guidelines (CPG) are one of the most effective ways to translate evidence of medical improvement into everyday practice. This study evaluated the dissemination and implementation of the Sexually Transmitted Infections-Korean Guidelines (STIKG) by applying the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) framework. A survey questionnaire was administered to clinicians via the internet. Among the 332 respondents, 190 (57.2%) stated that they were aware of STIKG and 107 (33.2%) implemented STIKG in their practice. The odds that a physician was exposed to STIKG (dissemination) were 2.61 times greater among physicians with previous training or education for any CPG than those who did not. Clinicians who indicated that STIKG were easy to understand were 4.88 times more likely to implement STIKG in their practice than those who found them not so easy. When a clinician's workplace had a supporting system for CPG use, the odds of implementation was 3.76 times higher. Perceived level of effectiveness of STIKG did not significantly influence their implementation. The findings of this study suggest that, ultimately, knowing how to engage clinicians in CPG implementation is as important as how to disseminate such guidelines; moreover, easy-to-use guidelines and institutional support are key factors.

A 24-year-old male visited our hospital because of pain in both flanks. His biochemistry profile showed an elevated serum creatinine level and low serum uric acid level. History taking revealed that he had undertaken exercise prior to the acute kidney injury (AKI) event, and he stated that family members had a history of urolithiasis. His renal profile improved after hydration and supportive care during hospitalization. Although the patient was subsequently admitted again due to AKI, his status recovered with similar treatment. Since the diagnosis of the patient was familial renal hypouricemia with exercise-induced AKI, we performed genotyping of SLC22A12, which encodes human urate transporter 1. The diagnosis was confirmed by the detection of a homozygous mutation of W258X. We herein, report a case of familial renal hypouricemia confirmed by genotyping of SLC22A12, and review the relevant literature.
