The term dilated(congestive) cardiomyopathy refers to a variety of cardiac disorders that have in common ventricular dilation and reduced myocardial contractility, and is derived from the common late clinical manifestation of congestive heart failure. Since echocardiography can evaluate several aspects of anatomical structures and cardiac function, it has provide a valuable contribution to the understanding of ventricular function and diagnosis of dilated cardiomyopathy. The purpose of this study is to perform the echocardiographic evaluation of left ventricular function in 44 patients with dilated cardiomyopathy and to compare the patients with normal individuals. The patients, 24 males and 20 females, had a mean age of 53.0 and body surface area of 1.61m2. Normal individuals as a control group, 10 males and 10 females, had a mean age of 47.2 and body surface area of 1.67m2. Among 44 patients with dilated cardiomyopathy, 22 cases had a history of heart failure and in 15 cases systolic murmur was heard at the apex. The cardiothoracic ratio was 0.7+/-0.1 on chest X-ray which showed significant difference when compared to normal control group, being 0.4+/-0.1(p<0.01) One case showed left ventricular thrombus and in 8 cases small mounts of pericardial effusion were noted. Among the 44 patients two had uremia, one had a history of myocarditis, one patient was young female whose illness began during the peripartum period and one had a diabetes mellitus. Results obtained were as follows; 1) Mitral valve echocardiogram (1) DE amplitude and EF slope of mitral valve(16.5+/-3.3mm and 83.5+/-3.65mm/sec respectively) showed significant decrease when compared to normal control group (20.1+/-3.0 mm and 102.4+/-28.9 mm/sec respectively) (p<0.01 and p<0.05). (2) EPSS (25.5+/-7.6mm) and the distance between posterior cusp of mitral valve and left ventricular posterior wall (9.1+/-2.1mm) showed significant increase (p<0.01) when compared to normal control group (7.1+/-2.1mm and 5.9+/-1.2mm). The ratio of the separation of two mitral leaflets to the left ventrticular diastolic dimension (0.4+/-0.1) showed significant showed significant decrease in patients when compared to normal control group (p<0.01) (3) Among 44 patients with dilated cardiomyopathy, 12 cases showed B-notch in mitral valve. 2) Echocardiographic findings of aortic valve. Left atrial size was markedly increased (37.7+/-7.5mm) when compared to nomal control group (29.1+/-4.9) (p<0.01). The ratio of left atrial size to aortic dimension was 1.3+/-0.3, showing significant increase when compared to normal control group (0.99+/-0.3) (<0.01). And 4 cases showed systolic notch in aortic valves. 3) Echocardiographic findings of left ventrcle and ventricular septum. (1) Left ventricular diastolic and systolic dimensions (41.8+/-7.8mm/m2 and 36.7+/-7.2mm/m2) were markedly increased in patient with dilated cardiomyopathy, when compared to normal control group (30.4+/-2.6mm/m2 and 11.4+/-3.2mm/m2) (p<0.1, both). Left ventricular diastolic and systolic volume (181.5+/-91.0ml/m2 and 136.6+/-69.7ml/m2) were also significantly higher in patients with dilated cardiomyopathy when compared to normal control group (79.1+/-23.8mm/m2 and 19.4+/-2.5ml/m2) (p<0.01, both). (2) Ejection fraction (0.32+/-0.10) percent fractional shortening (12.3+/-4.6) and mVcf (0.5+/-0.2 cric/sec) showed significant decrease in patients when compared to normal control group (0.74+/-0.05, 34.6+/-6.7 and 1.4+/-0.2) (p<0.01, all). Thus, We could find the reduced myocardial contractility in dilated cardiomyopathy. (3) Systolic amplitudes of venticular septum (LSa) and ventricular posterior wall (Ena) were markedly decreased (p<0.01). The sum of both values (LSa+ENa) also showed significant decrease (12.0+/-4.2mm) when compared to normal control group (p<0.01) (4) Thickness of ventricular septum and ventricular posterior wall showed slight increase in patients, but there was no significant changes when compared to normal group. 4) Systolic time interval Echocardiograms showed significant increase in ratio of preejection period to ejection time, when compared to normal group (p<0.01). Thus, the author observed that in dilated cardiomyopathy the contractility of left ventricle was significantly reduced and the left ventricular diameter and diastolic volume of left ventricle showed marked increase. And also the decreased motions of ventricular septum and posterior wall of left ventricle were noted.

STUDY DESIGN: A prospective study. PURPOSE: To assess postoperative changes in cerebral glucose metabolism in anxiety patients with lumbar spinal stenosis (SS). OVERVIEW OF LITERATURE: Although an association between preoperative anxiety and abnormal cerebral glucose metabolism may exist, only a limited number of studies using F-18 fluorodeoxyglucose positron emission tomography (FDG PET) have evaluated preoperative to postoperative changes in cerebral glucose metabolism in SS patients in detail. METHODS: The present study was designed to assess preoperative to postoperative changes in cerebral glucose metabolism in anxiety patients with SS. F-18 FDG PET with statistical parametric mapping analyses was used to compare preoperative and postoperative regional brain glucose metabolism in 18 SS patients. RESULTS: F-18 FDG PET scans showed postoperative activation of several brain clusters in gray matter. These included left parahippocampus, left cerebellar tonsil, left inferior semi-lunar lobule, and right cerebellar tonsil. Areas that were deactivated postoperatively were the right insula, left fusiform gyrus, left orbitofrontal cortex, left inferior frontal gyrus, left middle frontal gyrus, left precuneus, and left inferior frontal gyrus. CONCLUSIONS: SS patients with preoperative anxiety showed altered cerebral glucose metabolism at postoperative follow-up.

BACKGROUND: To evaluate the clinical results and operation technique of arthroscopic repair of combined Bankart and superior labrum anterior to posterior (SLAP) lesions, all of which had an anterior-inferior Bankart lesion that continued superiorly to include separation of the biceps anchor in the patients presenting recurrent shoulder dislocations. METHODS: From May 2003 to January 2006, we reviewed 15 cases with combined Bankart and SLAP lesions among 62 patients with recurrent shoulder dislocations who underwent arthroscopic repair. The average age at surgery was 24.2 years (range, 16 to 38 years), with an average follow-up period of 15 months (range, 13 to 28 months). During the operation, we repaired the unstable SLAP lesion first with absorbable suture anchors and then also repaired Bankart lesion from the inferior to superior fashion. We analyzed the preoperative and postoperative results by visual analogue scale (VAS) for pain, the range of motion, American Shoulder and Elbow Surgeon (ASES) and Rowe shoulder scoring systems. We compared the results with the isolated Bankart lesion. RESULTS: VAS for pain was decreased from preoperative 4.9 to postoperative 1.9. Mean ASES and Rowe shoulder scores were improved from preoperative 56.4 and 33.7 to postoperative 91.8 and 94.1, respectively. There were no specific complication and no significant limitation of motion more than 10 degree at final follow-up. We found the range of motions after the arthroscopic repair in combined lesions were gained more slowly than in patients with isolated Bankart lesions. CONCLUSIONS: In recurrent dislocation of the shoulder with combined Bankart and SLAP lesion, arthroscopic repair using absorbable suture anchors produced favorable clinical results. Although it has technical difficulty, the concomitant unstable SLAP lesion should be repaired in a manner that stabilizes the glenohumeral joint, as the Bankart lesion can be repaired if the unstable SLAP lesion is repaired first.

BACKGROUND/AIMS: Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) tract disorder that has heterogeneous clinical presentations such as abdominal pain, diarrhea, constipation, and abdominal distension. It is known that several mechanisms are involved in the pathogenesis of IBS. Probiotics may target one or more pathophysiologic pathways in IBS and may improve the symptoms of IBS. However, the results of studies about probiotics on IBS are controversial. Therefore, the aim of this study was to evaluate the effect of probiotics on GI symptoms and intestinal gas volume changes in patients with IBS. METHODS: Forty patients were randomly allocated to be treated with medilac DS(R) (Bacillus subtilis, Streptococcus faecium) (n=20) or placebo (n=20) in a double-blind, prospective manner. The change in intestinal gas volume and symptom scores after 4-week treatment were evaluated for the efficacy. RESULTS: There was no significant difference in bloating, frequency of gas expulsion, frequency of defecation, and hardness of stool before and after the treatment. However, the severity of abdominal pain and the frequency of abdominal pain decreased significantly in medilac DS(R)group (2.4+/-1.3 cm/day -> 1.6+/-1.6 cm/day, 1.7+/-1.3/day -> 1.0+/-1.0/day) (p=0.044, p=0.038), but not in placebo group (2.1+/-2.0 cm/day -> 1.8+/-2.1 cm/day, 1.3+/-1.2/day -> 1.4+/-1.9/day). In both groups, intestinal gas volume at baseline, after 2-week treatment, and after 4-week treatment did not show significant change. Medilac DS(R)was well tolerated without adverse events. CONCLUSIONS: Medilac DS(R)is a safe and useful probiotic agent for the treatment of abdominal pain in patients with IBS.

While it is generally considered that tuberculous meningitis (TBM) causes various vascular complications, there have been few reports of moyamoya syndrome following TBM. A 23-year-old female was diagnosed as TBM. Preliminary brain MRA yielded normal findings. Follow-up MRA and cerebral angiography conducted 1.5 years later yielded findings that were consistent with moyamoya disease. They showed no interval change after 2 years, and the patient had no neurological deficits. This patient with TBM subsequently developed moyamoya syndrome during the course of antituberculosis medication.

PURPOSE: Preoperative on-screen templating is a method of using acetate templates on digital images. The aim of the present study was to evaluate the accuracy, intra- and interobserver reliabilities of preoperative on-screen templating using digital radiographs for total hip arthroplasty (THA). MATERIALS AND METHODS: Two hundred patients with hip disease who were treated with primary cementless THA were retrospectively evaluated. The accuracy of on-screen templating was assessed by comparing the predicted prosthesis sizes with the actual sizes used operatively. The inter- and intraobserver reliabilities of the templating results were also evaluated. RESULTS: The prosthesis prediction accuracy within ±one size was 96.6% for the cup size and 97.8% for the stem size. The inter- and intraobserver reliabilities for the implant size were substantial (kappa>0.70). The intra- and interobserver reliabilities for the leg length discrepancy and femoral offset difference using the intraclass correlation coefficient ranged from 0.89 to 0.97. CONCLUSION: Preoperative on-screen templating using digital radiographs showed substantial accuracy and reliability for implant prediction. It is an effective method for predicting the size of implant, correcting the leg length discrepancy and restoring the femoral offset.

Biliary adenoma of the common bile duct is a rare disease found in biliary tract encounterd in biliary mass lesion, and it is difficult to differentiate from their malignant counterparts. Symptoms and signs of these tumors can mimic choleliathiasis and malignant tumors. Therefore, this tumor is rarely diagnosed preoperatively. In addition, there has been no reported case of a tubular adenoma of the common bile duct in Korea, until recently. We experienced a case of tubular adenoma of the common bile duct, which was diagnosed and partially resected by percutaneous transhepatic cholangioscopy. The patient was a 84-year-old male who showed abnormal liver function test. Abdominal ultrasonography showed a dilated common bile duct, and a soft tissue was observed on endoscopic retrograde cholangiography. This was initially thought as a stone, but it became partially detachable from the common bile duct during an endoscopic retrograde cholangioscopic basket removal. The mass lesion was partially resected by a percutaneous transhepatic cholangioscopic snare. This resected tissue was confirmed as a tubular adenoma.

PURPOSE: Gingko biloba extract (GBE), a natural product extracted from Gingko leaves, is known to increase the radiosensitivity of tumors. This radiosensitization probably arises from the increase in the peripheral blood flow by decreasing the blood viscosity and relaxing the vasospasm. The influence of a GBE on the metabolic status in fibrosarcoma II (FSaII) of a C3H mouse was investigated using 31P magnetic resonance spectroscopy (MRS). MATERIALS AND METHODS: Eighteen C3H mice with fibrosarcoma II (from 100 mm3 to 130 mm3) were prepared for this experiment. The mice were divided into 2 groups; one (9 mice) without a priming dose, and the other (9 mice) with a priming dose of GBE. The GBE priming dose (100 mg/kg) was administered by an intraperitoneal (i.p.) injection 24 hours prior to the measurement. First 31P MRS spectra were measured in the mice from each group as a baseline and test dose of GBE (100 mg/kg) was then administered to each group. One hour later, the 31P MRS spectra were measured again to evaluate the change in the energy metabolic status. RESULTS: In the group without the priming dose, the mean pH, PCr/Pi, PME/ATP, Pi/ATP, PCr/(Pi+ME) values 1 hour after the test dose were not changed significantly compared to the values at the baseline. However, in the group with the priming dose, the mean PCr/Pi, Pi/ATP, PCr/(Pi+PME) values 1 hour after the test dose changed from the baseline values of 0.49, 0.77, 0.17 to 0.74, 0.57, 0.28 respectively. According to the paired t-test, the differences were statistically significant. CONCLUSION: The above findings suggest that the metabolic status is significantly improved after administering GBE if the priming dose is given 24 hours earlier. This shows that the radiosensitizing effect of GBE is based on the increase of tumor blood flow and the improvement in the metabolic status.

BACKGROUND: A 9-year-old male showed severe defects in midface structures, which resulted in maxillary hypoplasia, ocular hypertelorism, relative mandibular prognathism, and syndactyly. He had been diagnosed as having Apert syndrome and received a surgery of frontal calvaria distraction osteotomy to treat the steep forehead at 6 months old, and a surgery of digital separation to treat severe syndactyly of both hands at 6 years old. Nevertheless, he still showed a turribrachycephalic cranial profile with proptosis, a horizontal groove above supraorbital ridge, and a short nose with bulbous tip. METHODS: Fundamental aberrant growth may be associated with the cranial base structure in radiological observation. RESULTS: The Apert syndrome patient had a shorter and thinner nasal septum in panthomogram, PA view, and Waters’ view; shorter zygomatico-maxillary width (83.5 mm) in Waters’ view; shorter length between the sella and nasion (63.7 mm) on cephalogram; and bigger zygomatic axis angle of the cranial base (118.2°) in basal cranial view than a normal 9-year-old male (94.8 mm, 72.5 mm, 98.1°, respectively). On the other hand, the Apert syndrome patient showed interdigitating calcification of coronal suture similar to that of a normal 30-year-old male in a skull PA view. CONCLUSION: Taken together, the Apert syndrome patient, 9 years old, showed retarded growth of the anterior cranial base affecting severe midface hypoplasia, which resulted in a hypoplastic nasal septum axis, retruded zygomatic axes, and retarded growth of the maxilla and palate even after frontal calvaria distraction osteotomy 8 years ago. Therefore, it was suggested that the severe midface hypoplasia and dysostotic facial profile of the present Apert syndrome case are closely relevant to the aberrant growth of the anterior cranial base supporting the whole oro-facial and forebrain development.
