PURPOSE: This study was conducted to review the curriculum and license examination of physical therapists in the United States. METHODS: The doctor of physical therapy (DPT) curriculum was evaluated by a review Course Work Tool version 6 (CWT6) data and current physical therapy licensure examination (National Physical Therapy Exam, NPTE) category in the United States. RESULTS: The results indicated that they were required to meet the doctor of physical therapist degree based on ‘Guide to Physical Therapist Practice’ of American Physical Therapy Association (APTA). This includes general education in the areas of communications and humanities, physical science, biological science, social and behavioral science, and mathematics. A minimum of one course must be completed successfully in each area of general education. Moreover, there should be at least 68 didactic credits of professional education and 22 clinical education credits, which is a minimum of two full-time clinical internships with no less than 1050 hours in total, which were supervised by a physical therapist. Regarding the physical therapy licensure examination, National Physical Therapy Exam (NPTE, 2016) consisted of a physical therapy examination (26.5%), evaluation, differential diagnosis, baseline of prognosis (32.5%), intervention (28.5%), protection, responsibility, and research (6.5%) based on the ‘Guide to Physical Therapist Practice’. CONCLUSION: Based on the study results provided above, it is considered a standard to meet domestic reality as the Guide to Physical Therapist Practice of APTA for South Korean physical therapists.

PURPOSE: Facial trauma is increasing along with increasing popularity in sports, and increasing exposure to crimes or traffic accidents. Compared to the 3D CT of 1990s, the latest CT has made significant improvement thus resulting in higher accuracy of diagnosis. The objective of this study is to compare 64 channel 3 dimensional volume CT(3D VCT) with conventional 3D CT in the diagnosis and treatment of facial bone fractures. METHODS: 45 patients with facial trauma were examined by 3D VCT from Jan. 2006 to Feb. 2007. 64 channel 3D VCT which consists of 64 detectors produce axial images of 0.625 mm slice and it scans 175mm per second. These images are transformed into 3 dimensional image using software Rapidia 2.8. The axial image is reconstructed into 3 dimensional image by volume rendering method. The image is also reconstructed into coronal or sagittal image by multiplanar reformatting method. RESULTS: Contrasting to the previous 3D CT which formulates 3D images by taking axial images of 1-2mm, 64 channel 3D VCT takes 0.625mm thin axial images to obtain full images without definite step ladder appearance. 64 channel 3D VCT is effective in diagnosis of thin linear bone fracture, depth and degree of fracture deviation. CONCLUSION: In its expense and speed, 3D VCT is superior to conventional 3D CT. Owing to its ability to reconstruct full images regardless of the direction using 2 times higher resolution power and 4 times higher speed of the previous 3D CT, 3D VCT allows for accurate evaluation of the exact site and deviation of fine fractures.

A retrospective analysis was performed on 49 patients with astrocytoma of glioblastoma multiforme of brain who received postoperative radiotherapy in the period between February 1979 and December 1985. Fourteen patients had grade I astrocytoma, 11 patients grade II, 14 patients grade III, and 10 patients glioblastoma multiforme. Three year actuarial surival rates were 85.7%, 44.6% and 23.1% for grade I,II, and III astrocytomas, respectively. One and 2 year actuarial survival rates for patients with glioblastoma multiforme were 54.5% and 27.3%, respectively. Histologic grade, age, extent of operation and tumor location were revealed to be prognosticators.

BACKGROUND/AIMS: We made a systematic review and evaluation of endoscopic cryotherapy of endobronchial tumors, investigating safety and efficacy. METHODS: Qualified studies regarding endoscopic cryotherapy of lung tumors were systemically evaluated using available databases according to predefined criteria. RESULTS: In total, 16 publications were included in the final assessment. A narrative synthesis was performed because a formal meta-analysis was not viable due to the lack of controlled studies and study heterogeneity. Overall success rates for significant recanalization of the obstruction were approximately 80%, although they varied, depending on disease status in the patient population. Complications from the procedure developed in 0-11.1% of cases, most of which were minor and controlled by conservative management. Although limited data were available on comprehensive functional assessment, some studies showed that respiratory symptoms, pulmonary function tests, and performance status were significantly improved. CONCLUSIONS: Endoscopic cryotherapy was found to be a safe and useful procedure in the management of endobronchial tumors although its efficacy and appropriate indications have yet to be determined in well-designed controlled studies.

α-Iso-cubebene (ICB) is a dibenzocyclooctadiene lignin contained in Schisandra chinensis (SC), a well-known medicinal herb that ameliorates cardiovascular symptoms, but the mechanism responsible for this activity has not been determined. To determine the role played by ICB on the regulation of vascular tone, we investigated the inhibitory effects of ICB on vascular contractile responses by adrenergic α-receptor agonists. In addition, we investigated the role on myosin light chain (MLC) phosphorylation and cytosolic calcium concentration in vascular smooth muscle cells (VSMC). In aortic rings isolated from C57BL/6J mice, ICB significantly attenuated the contraction induced by phenylephrine (PE) and norepinephrine (NE), whereas ICB had no effects on KCl (60 mM)-induced contraction. In vasculatures precontracted with PE, ICB caused marked relaxation of aortic rings with or without endothelium, suggesting a direct effect on VSMC. In cultured rat VSMC, PE or NE increased MLC phosphorylation and increased cytosolic calcium levels. Both of these effects were significantly suppressed by ICB. In conclusion, our results showed that ICB regulated vascular tone by inhibiting MLC phosphorylation and calcium flux into VSMC, and suggest that ICB has anti-hypertensive properties and therapeutic potential for cardiovascular disorders related to vascular hypertension.

BACKGROUND: The myelodysplastic syndromes (MDS) can be categorized as a group of clonal hematopoietic disorders characterized by ineffective hematopoiesis and peripheral cytopenias. Although the natural history of MDS varies, traditional treatments are not curative and allogeneic marrow transplantation offers potentially curative treatment for MDS. METHODS: In our center, 10 patients underwent allogeneic bone marrow transplantation (BMT) between December 1989 and May 1997. The minimum follow-up of 3 months was possible in 10 patients, for whom treatment-related complications and clinical outcomes were assessed. RESULTS: The median age of the 10 patients was 33 (range 20~40) years. The median time from diagnosis to BMT was 34 (3~116) months. By morphology, 5 patients had advanced MDS (i.e., RAEB, RAEB-t, CMML) and 5 patients had less advanced MDS (RA). By Bournemouth score, 8 patients had a score 2~3 and two patients had a score 4. By IPSS, 5 patients were in intermediate-1 group, 3 patients in intermediate-2 group and 2 patients in high risk group. Patients were prepared for transplant with either a total body irradiation (TBI)+cyclophosphamide (n=7), busulfan+TBI (n=2) and busulfan+cyclophophamide (n=1). All patients received CsA+short course MTX for GVHD prophylaxis. Successful engraftment was confirmed in all patients. The overall incidence of acute GVHD was noted in 70% (7/10 patients) and grade IV acute GVHD developed in 2 patients (20%). Five patients were evaluable for the development of chronic GVHD and 2 patients (40%) developed limited chronic GVHD. The duration of median follow-up was 8.1 months. At present five patients are alive and disease-free 3 to 21 months (median survival duration : 8.2 months) post-transplantation resulting in a 2-year disease-free survival of 44%. 2-year disease free survival was 63% in less advanced MDS and 25% in advanced MDS. CONCLUSION: Allogeneic BMT should be considered when any clinical evidence of disease progression to a more advanced stage becomes apparent. International prognostic scoring system (IPSS) and Bournemouth score can also be used to gauge timing for BMT. For patients were in intermediate-1 or intermediate-2 group by IPSS, BMT can be justified if the patient is young and has an HLA matched sibling donor.

BACKGROUND/AIMS: Lamivudine has demonstrated a potent suppression of viral replication and a substantial histologic improvement in many patients with chronic hepatitis B. This study is intended to evaluate the effects of lamivudine and the breakthrough rate in patients with HBV associated chronic liver diseases including decompensated liver cirrhosis, and to investigate the clinical factors closely related with these events. METHODS: A total of 58 patients(chronic hepatitis 21, cirrhosis 37) showing abnormal serum levels of aminotransferase and detectable serum HBV DNA for at least 6 month received 150 mg of lamivudine once a day for 3-27 months (median 13). The Kaplan-Meier methods and the Cox regression model were used for statistic analysis. RESULTS: The one-year cumulative incidences of the negative conversion of serum HBV DNA, normalization of aminotransferase, and seroconversion of HBeAg were 98.3%, 86.2% and 20.6%, respectively. Eighteen-month and 2-year cumulative breakthrough rates were 24% and 47%, respectively. The Child-Pugh scores were improved (p<0.001) in patients with decompensated liver cirrhoses(n=21). The negative conversion of HBV DNA, breakthrough rates and seroconversion were not significantly associated with the progression of disease, mutation in pre-core region and previous treatment with interferon. The pre-treatment aspartate aminotransferase (AST) level was associated with a higher rate of seroconversion(p<0.03). CONCLUSION: Despite a higher breakthrough rate, 2-year lamivudine treatment has induced the seroconversion of HBeAg in 26% of patients, and improved the clinical manifestations in decompensated cirrhotic patients.

BACKGROUND: The proper staging of advanced gastric cancer has crucial role in determining resectability and operative method, to prevent unnecessary operation and to predict the prognosis and survival rate. Although marked improvements have been made in computed tomography (CT) technology and endoscopic ultrasonography (EUS) in recent years, reassessment of the laparoscopy for gastric cancer is required as a preoperative staging tool. Therefore, we determined the usefulness of laparoscopy for staging of advanced gastric cancer without distant metastasis in CT and EUS. METHODS: Staging laparoscopy was performed in 48 patients with advanced gastric cancer staged T3 or T4 by CT and EUS. Laparoscopy was carried out with the patients under local anesthesia, and included visual inspection of abdomen, and biopsies for suspicious metastatic lesions. Laparoscopic results were compared with the postoperative pathologic findings. RESULTS: Laparoscopy was performed successfully in 48 patients. Laparoscopy disclosed unrecognized distant metastases in 7 patients (14.6%) judged to be eligible for potentially curative resection by CT and EUS. Preoperative laparoscopy showed an accuracy of 74% for serosal infiltration. CONCLUSION: Our results suggest that laparoscopy is an effective means of evaluating resectability of advanced gastric cancer staged T3 or T4 and can provide valuable help in planning surgical approach.

BACKGROUND/AIMS: It is suggested that diffuse esophageal spasm (DES), nutcracker esophagus (NUT), and hypertensive lower esophageal sphincter (HLES) could be re-classified together as a spastic esophageal motility disorder of similar clinical backgrounds. However, there were no studies to evaluate the pathophysiological characteristics of these motor abnormalities. The aim of the study was to evaluate the changes of esophageal motor function depending on the different types of the bolus (water vs semi-solid bolus). METHODS: Twenty-one healthy subjects and 42 subjects with primary esophageal motility disorders (4 DES, 12 NUT, 5 HLES, 12 nonspecific esophageal motility disorders, 9 normal) underwent a perfusion manometry with a low compliance pneumo-hydraulic capillary infusion system. Consecutively, each patient had 10 swallows of water and 10 swallows of Jello, 5 ml each. RESULTS: In the healthy controls, the Jello swallow showed an increased amplitude and duration of distal esophageal contractions, and the velocity of peristalsis was decreased (p < 0.05). Among all patients diagnosed by manometry with the water swallow, 2 cases diagnosed with HLES (40%) and 4 with NUT (33%) were changed to a diagnoses of DES after the Jello swallow. Moreover, HLES was found in 1 patient with DES (25%) and in 6 patients with NUT (50%). CONCLUSIONS: Semi-solid bolus swallows increase the contractile force of the esophagus more than water swallows. A conventional manometric diagnosis could be changed to a different spastic motility disorder of the esophagus after a semi-solid bolus swallow. It is suggested that DES, NUT, and HLES can be considered as a spectrum of spastic esophageal motility disorders sharing a similar pathophysiology.

BACKGROUND: The aims of this study were to evaluate the diagnostic value of pancreatic elastase-1(PE-1) in patients with pancreatic diseases and compare the significance of PE-1 with that of pancreatic exocrine function test by pure pancreatic juice (PPJ) collection. METHODS: For evaluation of PE-1, seventy nine patients with pancreatic diseases were examined. For evaluation of exocrine pancreatic function by PPJ, twenty three patients with Chronic pancreatitis(CP) were examined. PPJ was collected by endoscopic cannulation of main pancreatic duct under the intravenous bolus injection of secretin (0.25 CU/kg body weight) and cholecystokinin (CCK, 40 ng/kg body weight). RESULTS: Pancreatic exocrine functions were significantly decreased in patients with CP showing moderate and severe ductal changes on pancreatogram. The mean concentration of fecal PE-1 was significantly decreased in patients with CP and pancreatic cancer, but not in patients with acute pancreatitis. When we analyzed the PE-1 concentration according to Cambridge classification, the concentration of fecal PE-1 was significantly decreased only in patients with moderate and severe CP. With a cut off of 200 ug fecal PE-1/g, the sensitivity of PE-1 was 25%, 60%, and 100%, respectively, for mild, moderate and severe CP, and the specificity was 88.1%. The mean concentration of serum PE-1 was increased both in patients with acute and chronic pancreatitis, but there was no difference between both group. CONCLUSION: Fecal PE-1 is useful for diagnosis of pancreatic exocrine insufficiency in patients with CP, especially in moderate and severe grade of pancreatic exocrine insufficiency. The diagnostic value of fecal PE-1 was also similar to secretin-CCK test in pancreatic exocrine insufficiency.
