The purpose of this study was to evaluate the results of various types of opponensplasties which have been performed for the last 15 years. For the patients who had median nerve injury with or without ulnar nerve injury, we usually transferred the ECRL or ECRB to restore thumb opposition and Huber s procedure were usually done for thumb hypoplasia. With the criteria outlined by Sundararaj and Mani, postoperative function of 27 hands from 23 patients who underwent the opponensplasty from March 1981 to March 1995 were evaluated. The results from each etiology group were analyzed by the same criteria. Also subjective opinion of the patients about the scar were investigated by our own criteria. The analysis from overall 27 hands yielded 19 excellent (70.4%), 4 good (14.8%), 3 fair (11.1%), and 1 poor (3.7%) results with Sundararaj and Mani s criteria and 1 excellent (3.7%), 14 good (81.5%), 3 fair (11.1%), and 1 poor (3.7%) results about the scar. In 11 patients with nerve injury (median nerve with or without ulnar nerve injury), 7 excellent and 2 fair results were yielded by the ECRL or ECRB transfer, 1 excellent by Phalen-Miller's procedure, and 1 excellent by Burkhalter's procedure. In 8 patients with congenital hypoplastic thumb, 7 excellent results were yielded by Huber's procedure and 1 excellent by the ECRB transfer. In 8 patients with residual poliomyelitis or brachial plexus injury, the ECRB transfer yielded 3 excellent results. However, 2 good and 1 fair results were obtained by Bunnell's procedure; and l good, l poor by Camitz's procedure. In summary, the ECRL or ECRB transfer in the patients who had neuropathy, such as median with or without ulnar nerve injury, brachial plexus injury or residual poliomyelitis; and Huber's procedure in congenital hypoplastic thumb were thought to be one of the useful methods for the restoration of the thumb opposition.

PURPOSE: The Singh index which is based on a plain radiograph has commonly used in assessing the grade of osteoporosis. We studied value of the Singh index in assessing the grade of osteoporosis by obtaining reliability of the Singh index and correlation between the Singh index and bone mineral density. MATERIALS AND METHODS: Six observers assessed radiographs of 60 patients suspected osteoporosis. The interobserver and intraobserver agreement of the Singh index were obtained by using kappa statistics. The bone mineral density of proximal femur was measured by dual energy X-ray absorptiometry in all patients, and then the results of bone mineral density were compared with those of Singh index by using percentage of variance. RESULTS: The kappa values of interobserver agreement ranged from 0.28 to 0.76 (mean value: 0.45) and the strength of the agreement was moderate. The percentage of variance of BMD which was explained by Singh index was 7.1%. CONCLUSIONS: The results of this study suggest that the Singh index has low clinical value in assessing the grade of osteoporosis

PURPOSE: The main issue with the current ultrasonography (US) guidelines is the overestimation of malignant and indeterminate nodules as they do not aid in making decisions to treat patients. To overcome this, new US guidelines for thyroid nodules that have been shown to be better correlated with cytologic results have been proposed. We also suggested specific indications for US-guided fine needle aspiration (FNA) using the new US guidelines. METHODS: Clinical and pathologic data from 925 patients and 1,419 thyroid nodules were retrospectively collected. All subjects underwent US- and US-guided FNA at Department of Surgery, Wonju Christian Hospital, between March 2010 and July 2011. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were calculated for both the current guidelines and the new guidelines. RESULTS: The accuracy, sensitivity, specificity, PPV, and NPV for the current guidelines in predicting malignancy were 24.1%, 99.3%, 62.2%, 25.0%, and 99.8%, respectively. The accuracy, sensitivity, specificity, PPV, and NPV for the new guidelines in predicting malignancy were 66.0%, 96.0%, 86.7%, 47.7%, and 99.4%, respectively. CONCLUSION: The use of the new US guidelines allow for a more accurate and specific diagnosis and a better treatment plan than the current guidelines. Additionally, the use of the new FNA guidelines may help prevent unnecessary FNAs and promote cost-effective follow-up for patients.

OBJECTIVE: This research was performed to evaluate the relation clinical symptoms and P300 in patients with schizophrenia. METHODS: 25 patients with schizophenia by DSM-IV in Soonchunhyang Chunan University hospital were participated. Clinical symptoms were checked by BPRS (Brief Psychiatric Rating Scale) and PANSS (Positive and Negative Syndrome Scale). Auditory event related potentials P300 components were obtained with "Oddball paradigm". RESULTS: P300 in T 3 was smaller and more delayed than T 4 in patients with schizophrenia. Especially, P300 on T 3 were correlated with BPRS scores and negative symptoms scores of PANSS, which were also correlated with P300 on Fz. CONCLUSION: The results of this study suggest that P300 on frontal and left temporal lobe reflect clinical symptoms in patients with schizophrenia.

Pilomatricoma, known as calcifying epithelioma of Malherbe, is a deep dermal or subcutaneous tumor showing slow growth. There are some reports showing rapid enlargement of the tumors as a result of variable amounts of bleeding into the intratumoral cystic space and into the superficial dermis. We report an uncommon case of a rapidly enlarged pilomatricoma due to simultaneous in tratumoral and intradermal hemorrhage.
