Differential diagnosis of cavitary lung lesions is frequently problematic. We studied 35 patients with cavitary lung lesions, consisting of lung cancer (17 patients). Pulmonary tuberculosis(11 patients), and lung abscess (7 patients). We analysed CT scans in terms of irregularities of the cavity wall, maximum wall thickness, the presence of air-fluid level, location of the cavity within the mass, number of cavities within the mass, size of the cavity and the presence of calcification within the mass. Cancer cavity showed irregular inner (100%) and outer margins(100%), and thick wall (mean, 1.94cm), eccentrical location(94%) and multiplicity within a mass(38%). Tuberculous cavity showed smooth inner (56%) and irregular outer margins(75%), thin wall (mean 0.96cm), central location (62%), and multiplicity in one patient (36%). Abscess cavity showed irregular inner (57%) and outer margins(91%), relatively thin wall (mean 1.0cm), central location (57%), and air-fluid level (86%). CT scan could differentiate malignant lesions from benign condition such as tuberculosis and lung abscess by observing characteristics of the cavities.

BACKGROUND: No-reflow is a specific type of vascular damage occuring when removal of coronary occlusion dose not lead to restoration of coronary flow. There are three major explanations for the no-reflow phenomenon such as endothelial cell edema, microvascular plugging by platelets or thrombi and coronary occlusion by ischemic contracture of the myocardium. But detailed mechanisms of no-reflow phenomenon are not known. The objects of this study are to elucidate the possibility whether elevation of cytosolic Ca2+ concentration during ischemic cardioplegic period is mechanism of no-reflow phenomenon or not. METHODS: Changes in cytosolic Ca2+ concentration were measured under varying experimental condition. Free [Ca2+] in the cytosole [Ca2+]i of single rabbit coronary artery cells was measured with fluorescent Ca2+ indicator, Fura-2. RESULTS: Resting [Ca2+]i was 134.2+/-34 nM (n=43). When single cells were perfused with cardioplegic or ischemic cardioplegic solution, [Ca2+]i was significantly increased and degree of [Ca2+]i elevation was further augmented by ischemic cardioplegic solution. Pretreatment of sarcoplasmic reticulum emptying agent (20mM caffeine) had no effect on cardioplegia-induced [Ca2+]i change, but application of Ca2+ channel blocker (5x10-7M nifedipine) or an antagonist of Na+/Ca2+ exchange (5mM Ni2+ ) partially (nifedipine) or completely (nickel) inhibited the [Ca2+]i elevation. Pretreament of caffeine had no effect on ischemic cardioplegia-induced [Ca2+]i change, but application of nifedipine or nickel partially inhibited the [Ca2+]i elevation. Magnitude of ischemic cardioplegia-induced [Ca2+]i elevation was dependent on the Ca2+ concentration of perfusate from 0 to 2.5mM. When Ni2+ was added to reperfusion solution, recovery of ischemic cardioplegia-induced [Ca2+]i elevation was very rapid compared with control. CONCLUSIONS: From the above results, it may be speculated that ischemic cardioplegia-induced [Ca2+]i elevation may act as one of the mechanism of no-reflow phenomenon in rabbit coronary artery.

A buttonhole deformity of the finger is characterized by flexion of the pmximal interphalangeal joint and hyperextension of the terminal interphalangeal joint. When the central slip of the extensor tendon and the triangular ligament are ruptured,(or severed) on the base of the middle phalanx, buttonhole deformity will result.This article is based on clinical and follow up studies of 5 patients with buttonholedeformities. Five cases were treated by the modified Littler method and were followed from 4 months to 24 months postoperatively and good results were obtained in all cases.

Synovial chondromatosis is an uncommon benign lesion characterized by metaplastic cartilage formation within the synovial connective tissue which disintegrates into the joint and continues to grow. Of the eight cases of synovial chondromatosis seen by the authors, three cases involved the knee, two of these were bilateral, three cases involved the elbow, one the hip joint and one the proximal phalanx of the right middle finger. The diagnosis of synovial chondroamtosis was made by histopathological findings of the excised mass. Most synovial chondromatosis cases obtained favorable results by removing masses from the joint and at the same time performing a partial synovectomy, except one case in which degenerative arth ritis had developed proeoperatively.

PURPOSE: Combined chemoradiotherapy is standard management for locally advanced non-small cell lung cancer (LA-NSCLC), but standard treatment for elderly patients with LA-NSCLC has not been confirmed yet. We evaluated the feasibility and efficacy of concurrent chemoradiotherapy (CCRT) for elderly patients with LA-NSCLC. MATERIALS AND METHODS: Among patients older than 65 years with LA-NSCLC, 36 patients, who underwent CCRT were retrospectively analyzed. Chemotherapy was administered 3-5 times with 4 weeks interval during radiotherapy. Thoracic radiotherapy was delivered to the primary mass and regional lymph nodes. Total dose of 54-59.4 Gy (median, 59.4 Gy) in daily 1.8 Gy fractions and 5 fractions per week. RESULTS: Regarding the response to treatment, complete response, partial response, and no response were shown in 16.7%, 66.7%, and 13.9%, respectively. The 1- and 2-year overall survival (OS) rates were 58.2% and 31.2%, respectively, and the median survival was 15 months. The 1- and 2-year progression-free survivals (PFS) were 41.2% and 19.5%, respectively, and the median PFS was 10 months. Regarding to the toxicity developed after CCRT, pneumonitis and esophagitis with grade 3 or higher were observed in 13.9% (5 patients) and 11.1% (4 patients), respectively. Treatment-related death was not observed. CONCLUSION: The treatment-related toxicity as esophagitis and pneumonitis were noticeably lower when was compared with the previously reported results, and the survival rate was higher than radiotherapy alone. The results indicate that CCRT is an effective in terms of survival and treatment related toxicity for elderly patients over 65 years old with LA-NSCLC.

A prospective study was initiated to compare maternal serum concentration of CA-125 during the first trimester of normal and abnormal pregnancies. Serum specimens were obtained from 87 women with a normal intrauterine pregnancy and 47 women with abnormal pregnancies which were ended in spontaneo abortion or pathologically confirmed to be missed abortion. In normal pregnancies, the mean serum CA-125 concentrations were increased significantly from amenorhea 6 weeks (139.838.7 IU/ml), and were higher statistically than the values tested in the same weeks of abnormal pregnancies. In abnormal pregnancies serum CA-125 concentations were relatively lower than those of normal pregnancies. But these differences were not statistically significant except the values tested in amenorhea 6weeks. So serum levels of CA-125 may not be proved useful in monitoring of early pregnancies outcome.

PURPOSE: It is not common to evaluate the response of the fractionated stereotactic radiotherapy (SRT) to primary hepatoma as compared with conventional radiotherapy. The purpose of the study was to take the preliminary result on the clinical trial of primary hepatoma by SRT. MATERIALS AND METHODS: From July 1999 to March 2000, thirty three patients were hospitalized in the St. Mary's Hospital, and treated with SRT for extracranial tumors. Among them, 13 patients were diagnosed to primary hepatoma and then applied by frameless SRT using 6 MV linac accelerator. There were 12 male and 1 female patients. They had the age of 44~66 year old (median : 59) and the tumor size of 10~825 cc (median : 185 cc). SRT was given to them 3~5 fractions a week (5 Gy/fraction, 90% isodose line) for 2~3 weeks. Median dose of SRT was 50 Gy and the range was 30~50 Gy. RESULTS: Follow-up period ranged from 3 months to 13 months with median of 8 months. After treating SRT to thirteen patients with primary hepatoma, the response of the tumor was examined by abdominal CT : they are classified by 1 complete regression (7.7%), 7 partial regression (53.8%), 4 minimal regression (30.8%), 1 stable disease (7.7%). The positive responses more than partial remission were 8 patients (61.5%) after the treatment. The level of serum alpha-fetoprotein (AFP) after the treatment as compared with pretreatment had been 92.3% decreased. There was no severe complication except dyspepsia 84.6%, mild nausea 69.2%, transient decreased of hepatic function 15.4% and fever 7.7%. CONCLUSION: SRT to the patients with primary hepatoma was potentially suggested to become the safe and more effective tool than the conventional radiotherapy even though there were relatively short duration of follow-up and small numbers to be tested.
