PURPOSE: Tc-99m-tetrofosmin(TF) is a recently proposed myocardial imaging agent which has similar biokinetic characteristics to Tc-99m-sestamibi(MIBI). The aim of this study was to compare TF and MIBI myocardial perfusion SPECTs in detecting coronary artery disease. MATERIALS AND METHODS: One hundred and sixty patients(l0l males, 59 females, mean age 57+/-9 yr) who had undergone both myocardial perfusion SPECT (M- SPECT) and coronary angiography within 1 month were studied. M-SPECT was performed using TF in 115 patients and MIBI in 45 patients. Stress-rest one day protocol was used in all patients A coronary stenosis was considered significant when the luminal diameter > or =50% was compromised. The chi square test was used to compare, differences in sensitivity and specificity between the two groups. RESULTS: There was no difference in age and diseased coronary artery branches between the two groups. There were more male patients in TF group: Male-to-female ratios of TF and MIBI groups were 78:37 and 23:22, respectively (p<0.05). The overall sensitivity of TF study was 92% and specificity 36%. The overall, sensitivity and specificity of MIBI study were 93% and 30% respectively. There was no difference between TF and MIBI groups in identifying individual diseased coronary artery branches. CONCLUSION: One day stress-rest myocardial SPECT using either TF or MIBI was comparable and was a very sensitive test in detecting coronary artery disease.

PURPOSE: Myocardial SPECT is an effective test for detecting coronary artery disease in the general population. But the diagnostic accuracy between sexes is not defined. The purpose of this study is to compare the diagnostic accuracy between males and females. MATERIALS AND METHODS: One hundred and seventy seven male and 98 female patients who underwent myocardial SPECT within 1 month of coronary angiography were studied. Myocardial SPECTs were considered abnormal if fixed or reversible perfusion defects were detected. Stenosis severity of > or = 50% luminal diameter reduction of any artery defined coronary artery disease (CAD). RESULTS: Overall sensitivity for detection of CAD was 98% in men and 97% in women (p=not significant). However, specificities, accuracies, and positive predictive values (PPV) in men and women were 49% vs 31% (p<0.05), 81% vs 57% (p<0.01), 78% vs 48% (P<0.01), respectively Diagnostic accuracies for detection of right coronary artery disease were not different in both sexes, however, accuracies for detection of left anterior descending artery disease and left circumflex artery disease were significantly lower in female (p<0.05). CONCLUSION: A significant difference of diagnostic accuracy between sexes, especially in LAD and LCx disease, was noted. Artifacts from breast attenuation might be a cause for the lower diagnostic accuracy in female.

Extracorporeal shockwave therapy (ESWT) has been reported to be a safe and effective method for decreasing pain and relieving range of motion (ROM) limitations caused by neurogenic heterotopic ossification (NHO), though there has been no report that it might cause hematoma if applied to NHO. We hereby report a case of massive hematoma after ESWT, specifically the radial shockwave therapy (RSWT) device at both hips in a 49-year-old female patient with NHO. She had developed NHO after extensive subarachnoid hemorrhage. We had applied RSWT according to the previous report. The pain and the ROM limitations were gradually improved. Six weeks later, she reported pain and ROM limitations on the right hip. From a medial aspect, swelling and bruising of the right thigh could be seen. Magnetic resonance imaging and ultrasonography suggested a large hematoma between right hip adductor muscles. The symptoms disappeared after conservative treatment for one month, and subsequent follow-up imaging studies demonstrated resolution of the hematoma.

PURPOSE: We conducted this study to evaluate the role of dacryoscintigraphy in the diagnosis and treatment of pediatric patients with epiphora. MATERIALS AND METHODS: In 58 patients aged from 2 months to 15 years (mean age 2.8+/-2.3 years), dacryoscintigraphy was performed using a gamma camera with 4 mm pinhole collimator. We correlated symptoms with dacryosicntigraphic findings in all patients. In 37 patients who underwent ophthalmologic procedures, we analyzed the agreements of dacryoscintigraphic findings with the operation. RESULTS: High rates of agreements between epiphora and obstruction on dacryoscintigraphy (69/72, 95.8%), and between scintigraphic obstructive findings and operation sites (44/47, 93.6%) were noted. Nine of fourty-four (20.5%) asymptomatic eyes showed obstructive findings on dacroscintigraphy. CONCLUSION: In pediatric patients with epiphora, dacryoscintigraphy is a useful tool not only in diagnosing nasolacrimal duct obstruction but also in making a decision for therapeutic procedures.

PURPOSE: The methods for vasovasostomy are varied, and many authors have reported various success rates. This study aimed to assess a new method for vasovasostomy with a Prolene stent. MATERIALS AND METHODS: Among 85 patients who underwent vasovasostomy with a Prolene stent, 69 patients were retrospectively reviewed at our hospital between October 2004 and December 2007. The average age at the time of vasovasostomy was 42.2 years (range: 24.0-52.0 years). The obstructive interval was 6.25 years (range: 0.7-20.0 years). The cases were divided into 2 groups according to obstructive interval: group A (above 8 years) and group B (8 years and less), with 18 (26.1%) and 51 (73.9%) cases, respectively. Patency was defined as a sperm concentration of more than 10x106/ml on semen analysis. RESULTS: The overall patency and pregnancy rates were 76.8% and 43.4%, respectively. The patency and pregnancy rates of group A were 61.1% and 33.3%. Those of group B were 82.3% and 47.0%. The mean duration to pregnancy was 10.9 months (range: 4-31 months). The mean operation time was 90.2 minutes (range: 50.0-165.0 minutes). CONCLUSIONS: The new method of vasovasostomy with the Prolene stent has good efficacy and safety. Its benefits are the maintenance of good patency, a good pregnancy rate, and a diminished operating time.

Mucormycosis is a rare disease caused by fungi. Most commonly involved sites of mucormycosis infection are sinuses, lungs, skin and soft tissues. Systemic risk factors for mucormycosis are diabetes mellitus, neutropenia, corticosteroid use, hematological malignancies, organ transplantation, metabolic acidosis, deferoxamine use and advanced age. Local risk factors are history of trauma, burns, surgery and motor vehicle accidents. We present a case of cutaneous mucormycosis in a patient with diabetes mellitus. A 66-year-old female with uncontrolled diabetes mellitus, admitted with necrotizing lesion after minor abrasions on leg. We took a culture of the lesion and it is diagnosed with mucormycosis. Disease progressed despite administration of systemic amphotericin B. We performed above-knee amputation and changed antifungal agents into liposomal amphotericin B. A tissue biopsy showed nonseptate, irregularly wide fungal hyphae with frequent right-angle branching. Our case report suggests that patients with risk factors should be observed carefully.

OBJECTIVE: To determine which factors affect the rehabilitation duration in patients with congenital muscular torticollis (CMT) and to predict the duration of rehabilitation and prognosis. METHODS: One hundred and eighteen patients (79 males and 39 females) who were diagnosed with CMT and received physical therapy were enrolled in this study. We retrospectively reviewed the information in terms of sex, gestational age, birth weight, methods of delivery, fetal presentation, age at diagnosis, the affected sternocleidomastoid (SCM) muscle site, SCM muscle thickness, ratio of muscle thickness on the affected side to that on the unaffected side (called the 'abnormal/normal [A/N] ratio'), and range of motion for cervical rotation and side bending. RESULTS: The SCM muscle thickness and A/N ratio had a positive linear relationship with the rehabilitation duration. Patients who were in the breech position needed longer rehabilitation. The birth weight and age at diagnosis were negatively correlated with the rehabilitation duration. However, the cervical range of motion, mass site, sex, gestational age, and methods of delivery were not correlated with the rehabilitation duration. CONCLUSION: Patients with a thicker SCM, lower birth weight, and history of breech delivery had a longer rehabilitation duration.

A ganglion cyst is a relatively common benign tumor on the wrist. Conservative and surgical approaches have been used for its treatment. Various conservative treatment methods have been suggested such as reassurance, aspiration, sclerosant injection, and direct compression. But, there is no acceptable treatment of choice yet because each suggested method has a relatively high recurrence rate. We want to report two cases in which the size of the wrist ganglion was decreased by using electroacupuncture. One patient presented with a chronic ganglion for six years and the other patient presented with a recently occurred acute ganglion. We applied electroacupuncture for 20 minutes once a week for eight weeks to both of them. Afterwards, the size of the wrist ganglion diminished in the follow-up sonography and the accompanying pain was also relieved. Herein we report both cases along with a review of the relevant literature.

OBJECTIVE: To evaluate the effects of the videofluoroscopic swallowing study (VFSS) timing after the nasogastric tube (NGT) removal on swallowing function of the patients with dysphagia. METHODS: This study was conducted on 40 NGT-fed patients with dysphagia. To assess the patients' swallowing function, VFSS was performed twice using a 5-mL 35% diluted barium solution. For the initial examination, VFSS was performed immediately after the NGT removal (VFSS 1). For the second examination, VFSS was performed five hours after the NGT removal (VFSS 2). We used the functional dysphagia scale (FDS) to assess swallowing function. In the FDS, a significant difference in the four items in the oral phase, seven items in the pharyngeal phase, and total scores were assessed (p<0.05). We also used modified penetration-aspiration scale (mPAS) to compare the two examinations (p<0.05). RESULTS: A paired t-test was performed to confirm the statistical significance of the two examinations (p<0.05). The overall swallowing function was assessed as better in VFSS 2 than in VFSS 1. In the FDS, significant differences in the residue in valleculae (p=0.002), the residue in pyriform sinuses (p=0.001), the coating of pharyngeal wall after swallow (p=0.001), and the total scores (p<0.001) were found between the two examinations. Also, in the mPAS that assessed the degree of penetration-aspiration, a significant difference was found between the two examinations (p<0.001). CONCLUSION: The results of this study confirmed that the timing of the VFSS after the NGT removal affects the swallowing function. Thus, to accurately assess the swallowing function, VFSS must be performed in NGT-fed patients after they have rested for a certain period following the removal of their NGT.

We report a case in which traumatic epistaxis with a carotid cavernous fistula was successfully treated by using radiologic intervention. Since the inner facial bone is an anatomically weak structure and has numerous bleeding sites, traumatic epistaxis is profuse and can not be controlled well by using traditional treatments such as gauze, merocel(R), and foley balloon packing. Uncontrolled epistaxis may cause unstable vital signs and threaten the patient. In the case of failure through traditional treatments, angiographic embolization can be used as a treatment of choice because angiographic embolization can be done at a high success rate with few complications. Stroke, facial palsy, visual loss, and facial pain are the most common complications. In our case, we had tried traditional treatments first, but there was no marked improvement. After the angiographic embolization had been conducted, epistaxis was successfully controlled. The patient 's vital signs were stabilized, and he was admitted to the ICU.
