Acetabular bone deficiencies encountered during the revision hip arthroplasties should be recon- structed to provide the implant stability and to restore the normal center of rotation of hip and the leg length. We revised the loosened acetabular cup by grafting fresh-frozen bulk femoral head and inserting uncemented cup in 17 hips of 15 patients. The average follow-up period was 2 years and 3 months. The acetabular bone deficiencies were type 2A in 6 hips, type 2B in 8, type 3A in 1 and type 3B in 2 by Paprosky's classification. Three blocks of femoral head were grafted in 3 type 3 deficiencies, but only one in type 2 deficiencies. The cup-host bone contact was 41% on the average. However, the cup-host bone contact in the zone I was present only in 12 out of 17 hips and its average was 14%. Incorporation of the allograft into the host bone occurred between 5 months and 1 year and 7 months (average, 8,6 months) after revision surgery. Significant radiographic loosening sign was noted only in 2 hips which had not only type 3B bone deficiencies reconstructed with 3 blocks of femoral head allograft but also no cup-host bone contact in zone I . The bulk allograft of fresh-frozen femoral head demonstrated acceptable results in type 2 acetabular bone deficiencies, although the follow-up period was relatively short. Reconstruction of type 3B acetabular bone deficiencies by using multiple blocks of femoral head allograft had been failed. We presumed that the lack of the graft stability and the intimate contact between the grafts and host bone was the cause of failure.

Multiple sclerosis (MS) is a diagnosis of exclusion and the lesions or objective findings should disseminate in space and time to diagnose MS. The diagnostic criteria of MS have continuously evolved overtime. The McDonald criteria were originally proposed in 2001, and the revised 2010 McDonald criteria have been used widely. Scientific advances in the past 7 years since 2010 induced the revised 2017 McDonald criteria. All revisions relied entirely on the available evidences, and not expert opinion. In this review, we will provide an overview of the way to diagnose MS and the 2017 McDonald criteria.

Isolated and severe left main coronary ostial stenosis is a rare case. In the majority of these patients ostial stenosis was associated with any of the conditions known to involve the coronary ostia. These conditions include syphilitic aortitis, Takayasu's aortitis, familial hypercholesterolemia, and aortic valve disease. A 34-year young female patient was presented with exertional and stabbing anterior chest pain. There was no history of syphilis, diabetes mellitus, hypertension, hyperlipidemia and smoking. Coronary angiogram showed isolated left main coronary ostial stenosis. Transesophageal echocardiography(TEE) showed acute angle takeoff of the left main coronary artery. She underwent surgical angioplasty of coronary ostia with a patch of autologous pericardium. After angioplasty, TEE showed dilatation of left main coronary ostium and her clinical symptom improved.

PURPOSE: To introduce the minimal skin and orbicularis oculi muscle resection with the full thickness rotating suture technique for lower lid epiblepharon and to assess its surgical outcome. METHODS: A retrospective review of medical records was performed on lower lid epiblepharon patients who were followed for more than 6 months after surgical correction performed between January 2004 and December 2015. All surgeries were performed by one surgeon using minimal skin and orbicularis oculi muscle resection and the full thickness rotating suture technique for lower lid epiblepharon correction. RESULTS: A total of 943 lower lid epiblepharon patients (403 male, 540 female) were included in the analysis. The mean patient age was 6.7 ± 2.4 years, and the mean postoperative follow-up was 12.9 ± 7.2 months. Eyelid shape and function were well maintained in 904 patients (95.9%), with no recurrence during follow-up. Among the recurrent cases (39 patients [4.1%]), 19 patients (2%) underwent a second correction surgery. CONCLUSIONS: Minimal skin and orbicularis oculi muscle resection with the full thickness rotating suture technique for lower lid epiblepharon showed good surgical outcome with few complications and high success rate.

Cobb's syndrome, or cutaneomeningospinal angiomatosis, is a combination of the vascular skin nevus and angioma in the spinal cord within a corresponding segment or two to the dermatoms involved. A 15 year old girl showed the portwine nevus at T2-T11 dermatomes and multilevel spinal angioma at C7-L3 levels. She had suffered from a slowly progressive weakness of both lower extremities. Motor weakness of lower extremities improved after the combined rehabilitation management and radiation therapy for 4 months. We report the typical manifestations of Cobb's syndrome in a 15 year old girl with the brief review of literatures.

Benign abducens nerve palsy is rare in children. Identifiable causes of abducens nerve palsy include neoplasm, elevated intracranial pressure, infection and trauma. Isolated abducens nerve palsy with unknown etiology is classified as benign or idiopathic. The diagnosis is made by excluding underlying pathologies. Prognosis is favorable. Most patients have been found to recover spontaneously within 6 months. Recurrent palsy is observed in some patients and is more pronounced in younger girls with left-sided palsy. Even the recurrent cases, however, are still benign. We report a case of benign abducens nerve palsy presenting diplopia and headache with normal results from MRIs and microbiologic studies. The patient underwent rapid, spontaneous recovery.

BACKGROUND: The Stroop color word test is useful to examines the frontal lobe function of selective attention and inhibition. The Korean Color Word Stroop Test(K-CWST) was widely used in Korea. But, it was difficult in elderly individual with low educational level and visual problem and in patients with more progressed dementia. So we developed the Korean Stroop Test(KST). METHODS: The KST consist of word reading(WR), color naming(CN), interference word reading(IWR) and interference color naming (ICN). The interference tasks are naming the ink color of color words which were mismatched with word meaning. We measured reaction time and number of error. This study used the K-CWST to assess and compare the KST in eighteen probable alcohol related dementia patients and nineteen normal control. All subjects received the Korean version of Mini-Mental State Examination (K-MMSE) and the K-CWST and the KST. We tested reliability and validity of the KST. Also we enrolled normal adult from 41 to 80 year old for evaluating the change of the KST test with age. RESULTS: The KST tasks were correlated with K-MMSE -0.33(p<0.05) to -0.63(p<0.001) and K-CWST correlated with K-MMSE 0.37 (p<0.05) to 0.55(p<0.01). The interference color naming of KST was correlated the most to K-MMSE -0.78(p<0.001). The interference color naming of KST and interference color naming of K-CWST was correlated by 0.81(p<0.001). The internal consistency were 0.78 (Cronbach's alpha). The KST score was statistically different between alcohol related dementia patients and normal subjects in CN, ICN and ICN error. The KST was not differ in old age group except some tasks. CONCLUSION: The KST has a excellent reliability and validity. It takes less time and easy than the K-CWST. So the KST is a good test for evaluating frontal lobe function in elderly with low educational level of older people.

BACKGROUND: 67Ga scintigraphy has been used for years in sarcoidosis for diagnosis and to determine the extent of the disease. The present report is a study of various findings of 67Ga scintigraphy in patients with sarcoidosis. METHODS: Between 1998 and 2007, 16 patients (male:female, 6:10; age, 35.9+/-15.3 years) with histologically proven sarcoidosis underwent clinical evaluation and 67Ga scintigraphy. According to the site of involvement, they were divided into subtypes and analyzed. RESULTS: Sixteen patients with sarcoidosis had involvement of various organs, including lymph nodes (13/16, 81.3%), lung (3/16, 18.8%), muscle (1/16, 6.3%), subcutaneous tissue (1/16, 6.3%), glands (1/16, 6.3%), and bone (1/16, 6.3%). Sites of involved lymph nodes were thorax (12/13, 92.3%), supraclavicular area (5/13, 38.5%), inguinal area (2/13, 15.4%), abdomen (2/13, 15.4%), and pelvis (1/13, 7.7%). CONCLUSION: Because sarcoidosis frequently involves multiple organs, 67Ga scintigraphy is a useful method in for evaluating the whole body. Nuclear medicine physicians should be familiar with the various findings of gallium uptake in sarcoidosis.

PURPOSE: To evaluate the results of hypofractionated radiotherapy (HFX) for early glottic cancer. MATERIALS AND METHODS: Eighty-five patients with cT1-2N0M0 squamous cell carcinoma of the glottis who had undergone HFX, performed using intensity-modulated radiotherapy (IMRT, n = 66) and three-dimensional conformal radiotherapy (3D CRT, n = 19) were analyzed. For all patients, radiotherapy was administered at 60.75 Gy in 27 fractions. Forty-three patients received a simultaneous integrated boost (SIB) of 2.3–2.5 Gy per tumor fraction. RESULTS: The median follow-up duration was 29.9 months (range, 5.5 to 76.5 months). All patients achieved complete remission at a median of 50 days after the end of radiotherapy (range, 14 to 206 days). The 5-year rates for locoregional recurrence-free survival was 88.1%, and the 5-year overall survival rate was 86.2%. T2 stage was a prognostic factor for locoregional recurrence-free survival after radiotherapy (p = 0.002). SIB for the tumor did not affect disease control and survival (p = 0.191 and p = 0.387, respectively). No patients experienced acute or chronic toxicities of ≥grade 3. IMRT significantly decreased the dose administered to the carotid artery as opposed to 3D CRT (V₃₅, p < 0.001; V₅₀, p < 0.001). CONCLUSIONS: Patients treated with HFX achieved acceptable locoregional disease control rates and overall survival rates compared with previous HFX studies. A fraction size of 2.25 Gy provided good disease control regardless of SIB administration.

Background: Branch retinal artery occlusion (BRAO) is characterized by a sudden, painless monocular visual loss. The condition usually has a favorable prognosis but can sometimes cause severe visual loss. Currently, no clinical guidelines are available for the treatment of BRAO.Case Report: A 38-year-old man presented with vision loss. Initial visual acuity was 0.08/1.0 and a lower-altitudinal visual field defect was detected in the right eye. Occlusion of the superior temporal branch of the retinal artery was observed using fluorescein angiography. The patient was diagnosed with BRAO, and intra-arterial thrombolysis (IAT) was performed 11 hours after the first abnormality. The patient demonstrated rapid improvement after IAT. Visual acuity recovered to 0.8/1.0 and only the cecocentral scotoma remained at 5-month follow-up. Conclusion For patients with BRAO and severe vision loss, IAT may be an effective treatment. However, owing to potential complications, this procedure should be reserved for selected patients.
