PURPOSE: To investigate the results of surgical treatment of the symptomatic accessory navicular in adolescent. MATERIALS AND METHODS: 11 patients who were 11~16 years old with symptomatic accessory navicular were identified between 2001 and 2009. Six cases were diagnosed after trauma and 8 cases were diagnosed by accident with painful bony protrusion on medial aspect of foot. In cases after at least 3 months of ineffective conservative treatment, patients were treated by resection of accessory navicular and reattachment of tibialis posterior tendon to the apex of the medial longitudinal arch using periosteum and ligamentous soft tissue without transposition of its course. And then short leg cast was applied for correction of the flat foot (if it is combined) which was molded into the longitudinal arch with the talonavicular joint released and foot inverted during about 6 weeks. RESULTS: All were type II accessory navicular without tibialis posterior tendon lesions. In most cases pain was improved, results were excellent in seven and good in four. Calcaneal pitch angle and talus-first metatarsal angle was improved about 4.64degrees and 5.79degrees in average. CONCLUSION: Symptomatic accessory navicular in adolescent might not be associated with the tibialis posterior tendon lesions. The surgical treatment composed of excision of the accessory navicular with simple replication of the tibialis posterior tendon without altering its course led to good results in most cases. The procedure has a low rate of complications. And it is easy to be performed with a good satisfaction.

A case of malignant fibrous histiocytoma(MFH) arising from the pericranium which extend to the calvaria and the dura mater in a 32-year-old man is reported. This tumor presented as scalp induration and headache without any other neurologic abnormalities. Radical excision presented a surgical challenge because of the extensiveness of the lesion. In this case radical excision of pericranial and calvarial lesions were possible, however it is impossible to remove the lesion in the dura mater radically because of its extensiveness. Thus the radiation therapy was necessary after operation. Histologically, pericranial, calvarial and dura mater tumor tissues were same as that of the typical malignant fibrous histiocytoma of the soft tissue. The authors review the literatures of the MFH involving central nerve systems and discuss the management and the radiologic findings of this rare tumor.

OBJECTS: We developed the Korean version of Hasegawa Dementia Scale(HDS-K) by translating the revised Hasegawa Dementia Scale(HDS-R) which is known to be a useful brief screening instrument for dementia. MATERIALS AND METHODS: The translation was carried out keeping the basic structure of Revised Hasegawa Dementia Scale(HDS-R). HDS-K, along with MMSE-KC, SBT-K and CDR, were administered to 174 dementia patients and 160 elderly control subjects. Cronbach alpha coefficient, inter-rator reliability, and test-retest reliability of HDS-K were examined. The correlations of MMSE-KC, SBT-K and CDR with HDS-K were also examined to confirm the validity of HDS-K. Cut-off scores for dementia were estimated by Receiver Operator Characteristic(ROC) curve anslyses. By comparing Area Under Curve(AUC), the diagnostic efficiency of HDS-K was compared with those of MMSE-KC and SBT-K. RESULTS: 1) HDS-K was found to have significantly high internal consistency(Cronbach alpha coefficient=0.948, <0.01), inter-rater reliability(Pearson correlation coefficient=0.999, <0.01) and test-retest reliability(Pearson correlation coefficient=0.848, <0.01). 2) All the correlations of HDS-K with MMSE-KC, SBT-K and CDR were significant indicating that HDS-K has good concurrent validity. Its optimal cut-off point for dementia was estimated as 15/16, where the sensitivity and specificity were 0.950 and 0.902, respectively. 3) The ROC curve analysis indicated that the diagnostic efficiency of HDS-K(AUC=0.972) was comparable with MMSE-KC(AUC=0.951) and SBT-K(AUC=0.963). CONCLUSION: We conclude that HDS-K is a reliable, valid, and useful screening instrument for dementia.

OBJECTIVES: At present, the overall incidence of lung cancer is increasing, causing the age-adjusted lung cancer death rate to double every 15 years. Surgical resection of the tumor offers the best prospect of long-term survival in patients with lung cancer. Accurate prediction of postoperative ventilatory function should be helpful in determining in which patients the risk of surgery are acceptable. Exercise pulmonary function test has been widely applied to objective measure of work capacity, and can be extremely helpful for investigating exertional dyspnea. But no attempt is made to assess the contribution of the lung to be resected to performance, and it has been advocated as an additional predictor of postoperative complications. The present investigation was designed to evaluate the factors such as FEV1, FVC, VEmax, Vo2max, anaerobic threshold, heart rate reserve, breathing reserve and the corelation between FEV1 and VO2max at 4 weeks and 6months after resection in patients with lung cancer. METHODS: The eighteen of patients with lung cancer who considered surgically resectable underwent progre ssively incremental exercise test to symptom-limited stage before opera-tion, and also have done at surgical resection after 4 weeks, and 6 momths. Measurements were made of metabolic, cardiorespiratory, blood gases and symptoms during exercise test. RESULTS: 1) There were significant decreases in FEV1, FVC, VO2max, VE max in 4 weeks after operation and were more decreased in FEV1, FVC, VE max with significance, but fall in VO2max without significance in 6 month after operation. 2) There was a significant corre lation between the decrease of FEV1 and that of VO2max in 6 month after operation . Conclusions This result suggests that change of FEV1 is a relatively useful predictor of change in exercise performance after lung resection in 6 month after operation.

Though advances in immunosuppressive therapy have led to increased survival of renal transplant patients, but increased risk of developing infectious complications. Aspergillosis is a second common opportunistic fungal infection in a renal transplant patient. Lungs, brain and sinuses are the main targets of this fungal infection, but involvement of thyroid gland is rare. We report a case of disseminated aspergillosis with cutaneous aspergillosis and Aspergillus thyroiditis with thyrotoxicosis in a renal allograft patient.

Tracheobronchial rupture is considered to be a life-threatening condition and most commonly occurs after blunt trauma to the neck or chest. However, single- and double-lumen endotracheal tubes can cause serious airway injury. The recognition of this complication and a knowledge of the possible contributory factors is critical, because failure to do so could result in lethal events. We report the case of a 63-year-old male patient who developed pneumomediastinum three days after routine orotracheal intubation.

BACKGROUND/AIMS: Endoscopic biliary sphincterotomy (EST) has a very important role in the treatment of pancreatico-biliary diseases, but it has complications. We retrospectively investigated whether the types of electrosurgical currents affect occurence of complications. MEHTODS: In pancreatico-biliary diseases, consecutive 150 patients undergoing EST with pure cutting current (cutting group) and then consecutive 150 patient with blend current (blended group) were studied in respect to post-EST complications and the presence of periampullary diverticulum and papillitis in major papilla. Major bleeding was defined as a decrease in hemoglobin of at least 2 g/dL. Clinical pancreatitis was defined as abdominal pain with elevated serum amylase above three times about the upper normal limit after 48 hour. RESULTS: Major bleeding has not occurred. Minor bleeding occurred in 25/300 patients (8.3%), but was not different in cutting group (n=150) and blended group (n=150). Except 54 patients with elevated amylase before procedure, pancreatitis occurred in 13/246 patients (5.3%), but was not different in cutting group (n=122) and blended group (n=124). Two cases in blended group had moderate pancreatitis. There was no differences of bleeding, pancreatitis, in patients with diverticulum (n=112) and without diverticulum (n=188). Minor bleeding was more common in patients with papillitis (n=24) than without papillitis (n=276) (p=0.000), but the incidence of post EST pancreatitis was similar. In 235 patients with choledocholithiasis, there was no difference in terms of bleeding, pancreatitis in cutting group (n=120) and blended group (n=115). CONCLUSIONS: Post- EST bleeding and pancreatitis were not affected by the types of electrosurgical current used. When EST was performed in patient with papillitis, minor bleeding was observed commonly.

Hemodialysis (HD) patients continually exposed to heparin are at risk of developing heparin-induced thrombocytopenia (HIT). However, HIT is very rare in chronic HD patients with end-stage renal disease (ESRD). The authors report the case of a chronic HD patient with ESRD who developed HIT complicated by recurrent thrombocytopenia and significant bleeding episodes. A 67-year-old man with diabetic ESRD on chronic HD suddenly developed recurrent acute bleeding episodes and severe thrombocytopenia (platelet count <1.0x10(3)/uL) 2 months prior to presentation. These bleeding episodes and the thrombocytopenia always occurred 1 week after initiating HD with heparin, and improved within 1 week of discontinuing heparin. HIT was confirmed by ELISA for anti-heparin/platelet factor 4 antibody. HD was conducted successfully and thrombocytopenia did not occur after switching argatroban for heparin. This case report suggests that clinicians must consider HIT in the differential diagnosis of thrombocytopenia during maintenance HD.
