BACKGROUND: The erythromycin-resistance rate and phenotype distribution of Streptococcus propenes are quite different by geographical variation and study period. The aim of the present study was to determine the evolution of resistance to erythromycin and the frequency of erythromycin resistance phenotype of S. pyogenes isolated from Wonju Christian Hospital. METHODS: The minimal inhibitory concentrations (MICs) of erythromycin and clindamycin for 94 S. pyogenes isolated from clinical specimens between 1990 to 1998 were investigated. Double disk test of erythromycin (78microgram) and clindamycin (25microgram) were performed for 15 isolates of erythromycin resistant S. pyogenes to evaluate the erythromycin resistance phenotype. RESULTS: The resistance rates of 94 isolates of S. pyogenes were 16%(15/94) to erythromycin and 4%(4/94) to clindamycin. The frequency of erythromycin resistance phenotype in decreasing order were M phenotype (47%), inducible resistance phenotype (40%), and constitutive resistance phenotype (13%). Erythromycin-resistant S. pyogenes did not exist until 1993, but was isolated since 1994, and ranged from 14.0% to 24.0% during the period of 1994-1998. CONCLUSIONS: Our finding documents the emergence of high resistance rates to erythromycin in S. pyogenes at Wonju area since 1994. The M phenotype (47%) and inducible resistance phenotype (40%) account for the majority of erythromycin-resistant S. pyogenes.

PURPOSE: The residual intrahepatic stones with biliary strictures are difficult to remove percutaneously via T-tube tract after surgery in patients with recurrent pyogenic cholangitis. We evaluated the effectiveness of percutaneous balloon dilatation of benign biliary strictures. MATERIALS AND METHODS: The balloon dilatations with 6-12mm angioplasty balloon catheter and stone extractions were performed via a T-tube tract after surgical treatment in 15 patients with recurrent pyogenic cholangitis. The balloons were inflated for 3-4minutes under 5 atm. until disappearance of waist of the stricture site, from one to seven session. After balloon dilatation, residual stones were extracted with saline irrigation or stone basket. RESULTS: Among total 42 strictures, the balloon dilatation was succesful in 27 strictures(64.3%), partially successful in 12 strictures(28.6%), and failed in three strictures(7.1%). Single or central biliary strictures were dilated easily rather than multiple ductal strictures. Of 26 sites with residual intrahepatic stones, stone extraction was complete in 17 sites(65.4%), incomplete in seven sites(26.9%) due to impacted or large stone and acute ductal angulation, and failed in two sites(7.7%). CONCLUSION: Percutaneous balloon dilatation of benign biliary strictures is an effective procedure for extraction of residual intrahepatic stones associated with recurrent pyogenic cholangitis.

Systemic amyloidosis is an uncommon disease characterized by deposits of fibrillar aggregates of monoclonal immunoglobuloin light chains in vital organs. This amyloid deposit cause cardiac or renal dysfunction and ultimately, death. Cardiac amyloidosis may be asymptomatic or important causes of progressive heart failure and refractory arrhythmia. Cardiac involvement from AL amyloidosis is rapidly fatal. The amyloidoses are classified according to the biochemical nature of the fibril-forming protein. Cardiac amyloidosis is common in primary (AL) and heterofamilial amyloidosis and very rare in the secondary (AA) form. As we experienced a case of systemic amyloidosis affected heart, liver and kidney, which was confirmed by histology. We present a 57-year-old female case with literature review.

BACKGROUND: Noninvasive measurements that relate to the extent and severity of coronary atherosclerosis have long been sought for clinical screening of patients with chest pain syndromes and for use in clinical trials. Intima-media thickeness (IMT) of the carotid artery has been suggested to be associated with coronary artery atherosclerosis. In this study, we tried to assess the relation of carotid artery atherosclerosis by B-mode ultrasonography with presence and severity of coronary artery disease. METHOD: We studied 57 patients (36 men, 21 women) with ischemic heart disease, mean age 65+/-8 yrs (48 to 83 yrs), who underwent both coronary angiography and carotid ultrasonography with 10 MHz transducer. The patients who had received revascularization procedure were excluded. We classified the patients into two groups, the control group without significant coronary stenosis (18 patients) and the coronary artery disease (CAD) group (39 patients) with significant luminal stenosis (> or =50%). The CAD group was divided into single vessel disease group (SVD, 19 patients) and multivessel disease group (MVD, 20 patients). IMT was measured in far wall of common carotid artery (CCA) at 10 mm proximal to carotid bulb and abnormal IMT was defined if the measurement was greater than mean IMT+2SD of control group. Serum total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG), Lipoproteinp (a)(Lp(a)) were measured and history of hypertension, diabetes mellitus, and smoking were investigated. RESULTS: A significant difference in IMT of the CCA was found between control and CAD group (0.76+/-0.09 mm vs. 0.97+/-0.20 mm; p<0.0001). Also a significant difference in the number of atherosclerotic plaque was found between the two groups (control; 0.67+/-1.14 vs. CAD; 1.87+/-1.75; p<0.005). In the CAD group, both mean IMT and numbers of athero-sclerotic plaque tended to increase in MVD group compared with SVD group (1.03 mm vs. 0.91 mm; p=NS, 2.65 vs. 1.05; p<0.05). The sensitivity of IMT for prediction of significant CAD was 66.7%, the specificity 83.3%, the positive predictive value 89.7%, and the negative predictive value 53.6%. The sensitivity of plaque presence on the carotid artery for prediction of CAD was 71.8%, the specificity 61.3%, the positive predictive value 80.3% and the negative predictive value 50.5%. Among risk factor, diabetes mellitus and Lp (a) were correlated well with IMT of CCA, Hypertension was correlated with atherosclerotic plaque. History of smoking was correlated with coronary artery disease. CONCLUSION: Increases in IMT and plaque of the carotid artery, as measured noninvasively by ultrasonography, can be used as a predictor of significant coronary artery stenosis.

A 42-year-old woman presented with Hunt and Hess grade (HHG) III subarachnoid hemorrhage (SAH) caused by a ruptured left distal anterior inferior cerebellar artery (AICA) aneurysm. Computed tomography showed a thin SAH on the cerebellopontine angle cistern, and small vermian intracerebral hemorrhage and intraventricular hemorrhage in the fourth ventricle. Digital subtraction angiography revealed the aneurysm on the postmeatal segment of left distal AICA, a branching point of rostrolateral and caudomedial branch of the left distal AICA. Despite thin caliber, tortuous running course and far distal location, the AICA aneurysm was obliterated successfully with endovascular coils without compromising AICA flow. However, the patient developed left side sensorineural hearing loss postoperatively, in spite of definite patency of distal AICA on the final angiogram. She was discharged home without neurologic sequela except hearing loss and tinnitus. Endovascular treatment of distal AICA aneurysm, beyond the meatal loop, is feasible while preserving the AICA flow. However, because the cochlear hair cell is vulnerable to ischemia, unilateral hearing loss can occur, possibly caused by the temporary occlusion of AICA flow by microcatheter during endovascular treatment.

The patient is a 62-year-old man with known diabetes mellitus who presented with a two-weeks-history of dyspnea, cough, and fever. He was diagnosed with a lung abscess in the right upper lobe and was treated with intravenous antibiotics. The patient's clinical and radiological findings improved within seven days after medical treatment. However, newly developed ground-glass opacity and infiltrations were observed in the right lower lung. Fourteen days after admission, the patient's symptoms and imaging finding became aggravated despite trestment with susceptible antibiotics for lung abscess. Trans-bronchial lung biopsy (TBLB) was performed in the lateral basal segment of the right lower lobe of the lung. A histologic photomicrograph showed organizing pneumonia, also called bronchiolitis obliterans with organizing pneumonia(BOOP), that became more definite as the terminal bronchioles and alveoli became occluded with masses of inflammatory cells and fibrotic tissue. The clinical symptoms and radiograph findings resolved quickly with prednisone treatment. We report a case of secondary organizing pneumonia diagnosed after TBLB following lung abscess treatment and provide a review of the literature.

PURPOSE: To investigate the prevalence of paralytic ileus after spinal operation in the supine or prone operative position and to determine the efficacy of prophylactic gastrointestinal motility medications in preventing symptomatic paralytic ileus after a spinal operation. MATERIALS AND METHODS: All patients received spinal surgery in the supine or prone operative position. The study period was divided into two phases: first, to analyze the prevalence of radiographic and symptomatic paralytic ileus after a spinal operation, and second, to determine the therapeutic effects of prophylactic gastrointestinal motility medications (postoperative intravenous injection of scopolamine butylbromide and metoclopramide hydrochloride) on symptomatic paralytic ileus after a spinal operation. RESULTS: Basic demographic data were not different. In the first phase of this study, 27 patients (32.9%) with radiographic paralytic ileus and 11 patients (13.4%) with symptomatic paralytic ileus were observed. Radiographic paralytic ileus was more often noted in patients who underwent an operation in the prone position (p=0.044); whereas the occurrence of symptomatic paralytic ileus was not different between the supine and prone positioned patients (p=0.385). In the second phase, prophylactic medications were shown to be ineffective in preventing symptomatic paralytic ileus after spinal surgery [symptomatic paralytic ileus was observed in 11.1% (4/36) with prophylactic medication and 16.7% (5/30) with a placebo, p=0.513]. CONCLUSION: Spinal surgery in the prone position was shown to increase the likelihood of radiographic paralytic ileus occurrence, but not symptomatic paralytic ileus. Unfortunately, the prophylactic medications to prevent symptomatic paralytic ileus after spine surgery were shown to be ineffective.
