The widespread use of diagnostic radiography, especially using magnetic resonance imaging, has helped to increase the diagnosis of paralabral cysts in patients with chronic shoulder pain. These paralabral cysts are frequent in the anterior, the superior, and the posterior compartment of the shoulder joint but are rare in the inferior compartment. Paralabral cysts in the shoulder appear particularly in men in their third and fourth decades but rarely in elderly patients. We report a case of an inferior paralabral cyst in an elderly patient whom we treated through arthroscopic decompression.

PURPOSE: People with dementia have poor mobility and discharge outcomes following hip fractures. The purpose of this study was to evaluate the clinical and radiological results of internal fixation of undisplaced femur neck fractures (Garden types 1 and 2) by proximal femoral nail antirotation (PFNA) in dementia patients. MATERIALS AND METHODS: We studied retrospectively 19 patients with undisplaced femur neck fracture. All patients were over 70 years of age, walked independently with a cane or crutches and suffered moderate-to-severe dementia. Patients were treated with PFNA and followed-up for more than 2 years. Revision, loss of fixation, complications, and walking ability outcomes were measured. RESULTS: In walking-ability evaluation, patients showed an average decrease of just 0.2 points at the final follow-up. Walking ability was evaluated from before injury to 4 weeks after surgery and decreased by less than 0.5 points. Radiological bone union was achieved in 17 cases; the average time to bone union was 4.14 months (range, 2.5-7 months). Complications included non-union in two cases and femoral head avascular necrosis in one case of non-union. CONCLUSION: We found that for patients with osteoporotic bone tissues in their femoral heads or patients (e.g., those suffering dementia) for whom cooperating with medical workers for postoperative walking control or rehabilitation exercises is difficult, implanting a mechanically stable spiral blade for fixation of femoral neck fractures could facilitate walking after surgery.

PURPOSE: To compare the clinical and radiological results between internal fixation using the proximal femoral nail system and bipolar hemiarthroplasty (BHA) in reverse oblique intertrochanteric hip fractures in elderly patients. MATERIALS AND METHODS: From January 2005 to July 2012, we reviewed the medical records of 53 patients who had been treated surgically for reverse oblique intertrochanteric fracture and had been followed-up on for a minimum of two years. All patients were > or =70 years of age, and divided into two groups for retrospective evaluation. One group was treated with internal fixation using the proximal femoral nail system (31 cases), and the other group was treated with BHA (22 cases). RESULTS: Early ambulation postoperatively and less pain at postoperative three month were significantly superior in the BHA group. However, by 24 months postoperatively, the internal fixation group exhibited higher Harris scores and correspondingly less pain than the BHA group. There were no significant differences in union rate, duration of hospitalization or lateral wall fracture healing between the two groups. Four patients in the internal fixation group underwent reoperation. CONCLUSION: In the treatment of intertrochanteric fracture of the reverse oblique type, open reduction and internal fixation should be considered to be the better choice for patients with good health and bone quality. However, in cases of severe comminition of fracture and poor bone quality, BHA is an alternative offering advantages including early ambulation, less pain at early stages, and a lower risk of reoperation.

Coronary stent dislodgement during percutaneous coronary intervention, which occurs when the stent is passed through tortuous and calcified lesions, is not a rare complication. Without proper treatment, such as fixing with another stent in the coronary artery or removing the undeployed stent from the coronary artery or systemic artery system, this complication can cause serious problems. We experienced the unusual situation of a dismounted and dislodged coronary stent, in which retrograde retrieval to the radial artery was impossible during transradial coronary intervention. We report on use of a rendezvous and snare technique at the brachial artery level via femoral puncture, which resulted in resolution without surgery.

PURPOSE: To report a rare case of traction retinal detachment and retinal ischemia in inactive Takayasu's arteritis at ophthalmologic clinic. CASE SUMMARY: A 23-year-old woman presented with a floater, photophobia, and visual loss in her right eye one week prior to visit. She had no other systemic disease, such as diabetes mellitus or hypertension, or previous ophthalmic abnormalities except for a tumor in the adrenal gland. We found bilateral retinal ischemia and traction retinal detachment in the right eye on fundus examination without iris neovascularization. Pars plana vitrectomy, traction removal, endolaser treatment, and intravitreal bevacizumab injection were performed. Steroid eye drops and steroid systemic administration relieved the inflammation. On carotid doppler sonography, we found severe stenosis and thickness of the inner layer in both carotid arteries. We diagnosed the patient with an inactive phase of Takayasu's arteritis, which was conclusively correlated with the clinical features. Vascular anastomosis surgery along with follow-up was proposed by both the cardiology and vascular surgery departments. CONCLUSIONS: When a young patient presents with traction retinal detachment and retinal ischemia, Takayasu's arteritis should be considered for differential diagnosis and a systemic work-up should be performed as soon as possible.

The introduction of metagenomics into the field of virology has facilitated the exploration of viral communities in various natural habitats. Understanding the viral ecology of a variety of sample types throughout the biosphere is important per se, but it also has potential applications in clinical and diagnostic virology. However, the procedures used by viral metagenomics may produce technical errors, such as amplification bias, while public viral databases are very limited, which may hamper the determination of the viral diversity in samples. This review considers the current state of viral metagenomics, based on examples from Korean viral metagenomic studies-i.e., rice paddy soil, fermented foods, human gut, seawater, and the near-surface atmosphere. Viral metagenomics has become widespread due to various methodological developments, and much attention has been focused on studies that consider the intrinsic role of viruses that interact with their hosts.

PURPOSE: To investigate the clinical characteristics of patients with acute zonal occult outer retinopathy (AZOOR). METHODS: Medical records of 13 patients who visited Seoul National University Bundang Hospital from May, 2003 to May, 2015 and diagnosed with AZOOR were retrospectively reviewed. RESULTS: Thirteen patients (11 women and 2 men), with a mean age of 28.5 ± 11.4 years were followed for 42.8 ± 30.3 months. Visual field loss, photopsia, and blurred vision were common complaints. Initially, four patients had bilateral disease and seven patients showed bilateral involvement at the last visit. Mean best corrected visual acuity of involved eyes (BCVA) was 0.75 ± 0.32 (log MAR). Among 20 eyes with AZOOR, BCVA was 20/40 or better in 17 eyes (85.0%). The mean spherical equivalent was -4.59 ± 3.23 diopters (D), and 15 eyes (75.0%) had myopia less than -2.00 D. Nine eyes of seven patients (34.6%) had abnormal fundus findings. All patients underwent full field electroretinogram (ERG) or multifocal ERG and a visual field test. Thirteen patients (100.0%) showed a decreased response in ERG and visual field defects presented in every patient. With respect to the visual field test, 10 eyes (50.0%) showed improvement, 6 eyes (30.0%) had stationary status, and the progression of the visual field defect was observed in 4 eyes (20.0%). Among 13 patients, 4 (30.8%) patients showed flu-like symptom, 4 (30.8%) patients had fatigue, 2 (15.4%) patients had nausea, and 2 (15.4%) patients showed headache. CONCLUSIONS: AZOOR should be considered as one of the differential diagnoses, especially in female patients with myopia who show photopsia or visual field defects. ERG and visual field tests are necessary to confirm a decrease in retinal function and visual field loss. Central vision is preserved in most cases and recovery of visual field defect occurs often.

The authors presented a 17 months old female with malignant osteopetrosis, who was admitted to the Pediatric Department of Kyung Hee University Hospital on May, 1981 because of epistaxis and growth retardation. Diagnosis was made by typical clinical manifestations, hematologic and radiologic findings, such as frontal bossing, opened anterior fontanel, exophalmoses, strabismus, optic atropy, marked hepatosplenomegaly, severe anemia, thrombocytopenia, reticulocytosis and typical mask sign and sun burst sign at the skull X-ray, wide dense ribs with fracture at the vertebrae, clubbings at the distal parts of the femurs and radii and at the proximal parts of the tibias and humerii transverse bands at the metaphyses, and finally increased density of the entire skeleton on the bone scanning and marked decrease uptake of 99mTc on the bone marrow scanning. Prednisolone was administrated orally, resulted in gradual improvement of hematologic abnormalities to the normal range, associated wited with increased cellularity of the bone marrow and increased uptake of 99mTc and decreased spleen size on the bone marrow scanning after one month of therapy.
