BACKGROUND: Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. METHODS: The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. RESULTS: The PEFR measured with MPFM was significantly related to the PEFR and FEV1 measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r=0.92 p<0.001; for FEV1, r=0.78 ; p<0.001). The accuracy of MPFM was within 10%(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being I 6.5L/min(percentage of difference being 2.90%) or 1 0.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or -20.49~ + 9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p>0.05) and the coefficient of variation(2.4 1.2%) of PEFR measured with MPFM was significantly lower than that( 5.2 3.5%) with standard pneurnotachygraph in normal (p<0.05). CONCLUSION: This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.

Symptomatic aneurysmal bone cysts with expansible lesions in the pelvis are rare in children. The management of an aggressive vascular lesion in a female child is challenging. The standard treatment for aneurysmal bone cysts is accompanied by a high risk of local recurrence. A 12-year-old female presented with a history of pelvic pain for 5 months. Plain radiographs and magnetic resonance imaging showed a very large expansile lytic lesion arising from the right iliac bone. Intralesional curettage, electric cauterization, chemical sclerotherapy and allogeneic bone graft were performed through the window of the iliac crest. At a follow-up consultation 3.5 years post-surgery, the child had painless full-range movement in the hip joint with no recurrence. Although many treatment options are described, our patient was treated successfully using curettage and allogeneic bone graft without recurrence.

PURPOSE: The purpose of this study is to investigate the relative surgical risk and problems in hip hemiarthroplasty for treatment of an unstable intertrochanteric fracture in elderly patients over 80 years old. MATERIALS AND METHODS: Between April 2005 and May 2010, 58 patients whose age was over 80 years were available for inclusion in this study. They were divided into two groups: group 1 included 30 patients with femoral neck fracture and group 2 included 28 patients with intertrochanteric fracture. No significant differences in average age, concomitant disease, and walking ability before development of fracture were noted between the two groups. The following factors, including interval from development of fracture to operation, operation time, amount of blood loss, start time of walking after operation, duration of hospital stay, complications, revision rate, and walking ability were compared between the two groups. RESULTS: Operation time was an average of 85.2 minutes in group 1 and 97.5 minutes in group 2(P=0.03). The amount of bleeding was an average of 483 cc in group 1 and 695 cc in group 2(P=0.006). Similar results for walking start and recovery of walking ability after operation were observed in the two groups. No significant differences were observed in duration of hospital stay, complications, and revision rate. While 25 patients in group 1(83.3%) showed restoration of walking ability after operation to the same level of walking before injury, 19 patients in group 2(67.8%) showed restoration of walking ability postoperatively. CONCLUSION: Even though patients in group 2 showed a longer operation time and a higher amount of blood loss, compared with those in group 1, patients in group 2 had similar surgical risk and complications, compared with those in group 1. Therefore, primary hip hemiarthropalsty could be a good treatment option for intertrochanteric fracture in elderly.

Transmycardial laser revascularization has made its position as a sole therapy for patients with chronic angina nonamenable to maximal medical therapy, percutaneous transluminal coronary angioplasty, and coronary artery bypass grafting. We report three cases of transmyocardial laser revascularization as a sole therapy for patients with recurrent angina after CABG.

Intrsneural ganglion cysts of the peroneal nerve are rare. The precise etiology and pathological changes remain obscure. We have experienced recently a case of intraneural ganglion cyst developed in the sheath of the peroneal nerve. A 28 year old male had suffered from lump producing pain over the posterolateral aspect of the upper portion of the fibula, weakness of dorsiflexion of the ankle and of extension of the toes and diminution of sensation on the dorsum of the foot. He underwent excision of the ganglion and the prognosis for recovery of function is good.
