45,X/47,XYY mosaicism is a rare sex chromosomal disorder with clinical information limited to 25 cases in the literature. We report an unusual mosaic Turner syndrome case in a 35-year old Korean woman with a phenotypic female, primary amenorrhea, short stature, immature secondary sexual characteristics. Cytogenetic analysis including G- and Q-banding revealed 45,X/47,XYY mosaicism, and SRY gene was demonstrated by polymerase chain reaction(PCR). Prophylactic bilateral gonadectomy was performed because the presence of Y-chromosomal sequences in Turner stigmata may predispose this patient to gonadoblastoma formation.

Tumor lysis syndrome is one of the major oncological emergency. It causes complications such as acute kidney injury, cardiac arrhythmia, and death. However, it is rare in solid tumors. We report on a case of a patient with myoma of uterus who developed tumor lysis syndrome and acute kidney injury after high intensity focused ultrasound (HIFU) treatment. The potential complications of tumor lysis syndrome should be considered in HIFU treatment.

Treatment strategies for patients with coronary artery disease (CAD) should be based on objective evidence of inducible ischemia in the subtended myocardium to improve clinical outcomes, symptoms, and cost-effectiveness. Fractional flow reserve (FFR) is the most verified index to-date for invasively evaluating lesion-specific myocardial ischemia. Favorable results from large clinical trials that applied FFR-guided percutaneous coronary intervention (PCI) prompted changes in coronary revascularization guidelines to emphasize the importance of this ischemia-based strategy using invasive coronary physiology. However, the frequency of functional evaluations is lacking in daily practice, and visual assessment still dominates treatment decisions in CAD patients. Despite recent efforts to integrate functional and anatomical assessments for coronary stenosis, there is considerable discordance between the 2 modalities, and the diagnostic accuracy of simple parameters obtained from current imaging tools is not satisfactory to determine functional significance. Although evidence that supports or justifies anatomy-guided PCI is more limited, and FFR-guided PCI is currently recommended, it is important to be aware of conditions and factors that influence FFR for accurate interpretation and application. In this article, we review the limitations of the current anatomy-derived evaluation of the functional significance of coronary stenosis, detail considerations for the clinical utility of FFR, and discuss the importance of an integrated physiologic approach to determine treatment strategies for CAD patients.

STUDY DESIGN: A prospective study. OBJECTIVES: To report the results of new designed dual growing rods system for progressive pediatric spinal deformity. SUMMARY OF LITERATURE REVIEW: The current expandable spinal implant system appears effective in controlling progressive pediatric spinal deformity, allowing for spinal growth. However, there was no report concerning the growing rod in Korea. MATERIALS AND METHODS: Between 2010 and 2011, seven pediatric patients, who had a minimum of 1year follow-up, had undergone surgery for spinal deformity correction with a dual growing rods technique. We analyzed the demographic and radiologic data, including height, weight, age at surgery, diagnosis, number of lengthening, Cobb's angle of the major curve, thoracic kyphosis angle, lumbar lordosis angle, T1-S1 length, instrumented segment length, and complications, from the preoperative period to the last follow up period. RESULTS: Four male and three female patients with 5 neuromuscular scoliosis, 1 idiopathic juvenile osteoporosis and 1 spondyloepiphyseal dysplasia had underwent corrective surgery with dual growing rods. The mean age at the initial surgery was 11.6 years (7-13.8). The mean follow-up duration was 19.3 months (12-24), and the mean lengthening procedure time was 2.8 (2-4) for every patient. Cobb's angle of scoliosis curve was corrected from preoperative 80.2degrees(55-136) to 37.6degrees (15-81) on the last follow-up. Thoracic kyphosis angle and lumbar lordosis angle were changed from preoperative 48.7degrees(12-101) and 38.3degrees(9-72) to 44.5degrees(12-75) and 18.8degrees(1-46) on the last follow-up, respectively. Growth length during the follow-up period was measured as instrumented segment is 46 mm (33-59) and T1-S1 segment is 82 mm (66-98). Complications, such as breakage of rod in 3 cases and soft tissue infection in 1 case, occurred during the follow-up period. CONCLUSIONS: New designed dual growing rods system for pediatric patients with progressive spinal deformity is an effective and relatively safe method because of adequate correction and acceptable rate of complications.

Mycobacterium massiliense which is recognized as a separate species from M. abscessus is little known regarding its clinical patterns and the response to treatment. We present a case of a localized cutaneous infection due to M. massiliense of the sole associated with acupuncture. M. massiliense was identified via polymerase chain reaction-hybridization analysis. We treated the patient with single-drug therapy consisting of clarithromycin for 4 months and the patient showed a significant response to this treatment.

Osmotic demyelination syndrome is a demyelinating disorder associated with rapid correction of hyponatremia. But, it rarely occurs in acute hypernatremia, and it leads to permanent neurologic symptoms and is associated with high mortality. A 44-year-old woman treated with alternative medicine was admitted with a history of drowsy mental status. Severe hypernatremia (197mEq/L) with hyperosmolality (415mOsm/kgH2O) was evident initially and magnetic resonance imaging revealed a high signal intensity lesion in the pons, consistent with central pontine myelinolysis. She was treated with 0.45% saline and 5% dextrose water and intravenous corticosteroids. Serum sodium normalized and her clinical course gradually improved. Brain lesion of myelinolysis also improved in a follow-up imaging study. This is the first report of a successful treatment of hypernatremia caused by iatrogenic salt intake, and it confirms the importance of adequate fluid supplementation in severe hypernatremia.

Antiphospholipid syndrome (APS), the most common acquired hypercoagulable condition, is diagnosed by persistent presence of antiphospholipid antibodies and episodes of vascular thrombosis. It may be an important predisposing factor for stent thrombosis, resulting in poor outcomes. Also, anti-platelet therapy non-responsiveness is associated with stent thrombosis. We report a case of a 39-year-old man who after undergoing successful percutaneous coronary intervention for significant coronary artery disease suffered repeated stent thrombosis events leading to ST-segment elevation myocardial infarction. Eventually, he underwent coronary artery bypass surgery because of uncontrolled thrombosis and was diagnosed as having APS and dual antiplatelet therapy non-responsiveness.
