1.Clinical Study of Kienbock's Disease
The Journal of the Korean Orthopaedic Association 1989;24(5):1419-1424
Kienbock's disease is a rare disease that is suspected to be caused by the circulatory impairment or/and trauma to the lunate. The various modes of etiology, progression and the treatment have been suggested without any definite ones. The authors report 13 cases of the Kienbock's disease and the results are as follows:1. The male(10 of 13 patients) and the dominate hand(10 of 13 hands) were the more prevalent. 2. Eight cases had a definite history of trauma and the 5 of them were injured by the hyperextension of the wrist. 3. Eight cases were stage III B according to the Lichtman's classification. 4. Nine cases(69%) showed ulna minus variant, which was thought to have certain significant relation with the cause of this disease.

A histopathologic study including iramunohistochemical stains was made in 30 patients who were presented with gastrointestinal lymphoma. The occurrence was 13 in the stomach, 8 in the ileocecum, 7 in the small intestine and 2 in the colon. The disease more frequently affected males than females and the average ages were 53 years in the patients of gastric lymphoma and 44 years in the patients of intestinal lymphoma. Gastric lymphomas were usually presented with a single lesion, and the antrum and/or body were the most common sites. But intestinal lymphomas were presented with a single or multiple lesion, and the ileocecum was the most common site. The most common gross type of gastrointestinal lymphomas was the ulceroinfiltrating type and most are of the diffuse large noncleaved cell type of B-cell lymphoma, histologically. There were 2 cases of T-cell lymphoma presented in the intestine as the superficially ulcerative gross pattern and diffuse immunoblastic cell type. The distinct MALToma was seen in only one case of stomach but the feature was partially remained in each two cases of stomach and intestine. Their coexistent findings may suggest that diffuse large of immunoblastic component arises through blastic transformation of the low-grade M ALToma component.

Atrial flutter is and infrequent, but potentially unstable tachyarrythmia that occurs in pediatric ages. Transesophageal atrial pacing was used for treatment of 10 episodes of atrial flutter in 7 patients. At the time of atrial flutter conversion, patients were 6 days to 14 years old. 6 patients had associated with congenital heart disease. The atrial cycle length of atrial flutter ranged from 140 to 280 msec with variable atrioventricular conduction. Transesophageal atrial pacing was performed using a bipolar 4 F transesophageal electrode catheter. Atrial flutter conversion was accomplished with stimulation bursts using about 5 seconds of stimuli, 10 msec in duration at 20 to 27 mA. Pacing cycle length was 45 to 110 msec less than the atrial cycle length of tachycardia in 6 episodes. But in a neonate, underdrive pacing converted atrial flutter to sinus rhythm. Conversion attempts were unsuccessful on 2 occasions. Transesophageal atrial pacing is a safe and effective, minimally invasive technique for treatment of atrial flutter in infants and children.

Alterations in the expression of genes that control the cell cycle may be of critical importance in tumorigenesis and malignant transformation. The major regulatory events leading to cell proliferation occur in Gl phase of cell cycle, and the deregulated expression of Gl cyclins is related to oncogenesis. Cyclins Dl and E play important roles in the progression of cell through Gl phase of the cell cycle. Amplification and/or overexpression of the cyclin Dl gene and aberrant expression of cyclin E has been described in various forms of human cancer. However, the role of cyclins Dl and E in cervical cancer has been poorly defined. In this study, we examined the expression of cyclins Dl and E by Northern blot technique and the status of human papil- lomavirus(HPV) type 16 and 18 by polymerase chain reaction in 25 cases of cervical carcinoma to explore the relationship between cyclins Dl and E and cervical cancer. We found cyclin Dl expression showed down-regulated expression in cervical cancer but cyclin E expression was increased in cancer group. Other clinicopathological prognostic factors were not correlated with cyclins D1 and E expression. Further study based on larger numbers of cases with correlation of cyclins D1 and E status and survival data will be needed to elucidate the use of cyclin expressions as prognostic factor.

PURPOSE: We evaluated the capability of MR in the diagnosis of anomalous pulmonary venous connection (APVC). MATERIALS AND METHODS: The patient group consisted of 11 total APVC and 8 partial APVC diagnosed with MR. Echocardiography was performed in all cases, cardiac angiography in 12 cases and operation in 12 cases. We compared MR findings with those of operation, echocard iography and cardiac angiography. RESULTS: In surgically proven 12 cases, diagnostic accuracy of preoperative MR, echocardiography and cardiac angiography was 100%, 67% and 63%, respectively. In the remaining cases, MR findings well correlated with those of echocardiography or cardiac angiography. Stenosis of common pulmonary vein or superior vena cava was identified in 4 cases. In one patient, MR depicted associated cor triatriatum clearly. CONCLUSION: MR is an effective modallty in depicting anomalous pulmonary venous con nections.

Kawasaki disease (KD) is an immune-mediated disease which is a leading cause of acquired cardiovascular disease in developed country. Recently, tumor necrosis factor-alpha (TNF-alpha) blocker, infliximab has been considered a promising option for patients with refractory KD. Although chronic use of a TNF-alpha blocker could increase risk of opportunistic infections, a few studies have documented that use of infliximab was safe without serious adverse effects in patients with KD. We observed serious bacterial infection after infliximab treatment in an infant with refractory KD. Our patient was a 5-month-old male infant diagnosed with KD who did not respond to repeated doses of intravenous immunoglobulin. We effectively treated him with a single infusion of infliximab (5 mg/kg), but gram-negative (Acinetobacter lwoffii) septicemia developed after infliximab infusion. Therefore, we report a case of serious septicemia after treatment with infliximab, and suggest considering the risk of severe infection when deciding whether to prescribe infliximab to an infant with refractory KD.

BACKGROUND: Angiogenesis plays a critical role in human tumor growth and metastasis. Microvessel count, as a measure of tumor angiogenesis, has been significantly correlated with invasive and metastatic patterns in breast, prostate and cutaneous carcinomas. Materials and METHODS: Fifty patients with curatively resected non-small cell lung cancer were evaluated. Tumor tissues embedded in paraffin block were stained by anti CD 31 (PECAM, platelet endothelial cellular adhesion molecule) using immunohistochemical method to assess microvessel count. Microvessels were counted in the most active areas of neovascularization(microscopy, 200×). RESULTS: 1) Mean microvessel count was 47.1 ± 17.7(per 200×field) in total 50 cases. 2) Mean microvessel count of adenocarcinoma (54.4±19.9) was significantly higher than that of squamous cancer(43.9±16.2)(p<0.05), but there were no relationship between microvessel count and TNM stages. 3) Median survival time, 2-year and 5-year survival rates of the low microvascular group(microvessel count<45, 22cases) were 61 months, 80% and 40%, respectively, and those of the high microvascular group(microvessel count ≥ 45, 28 cases) were 46 months, 75% and 12%, respectively. As results, prognosis of low microvascular group is statistically significantly superior to that of the high microvascular group(p=0.0162, Kaplan-Meier, log-rank). CONCLUSION: Angiogenesis assessed by microvessel count can be used as one of the significant prognostic factors in non-small cell lung cancer.

BACKGROUND: Angiogenesis is an essential component of tumor growth and metastasis, and the vascular endothelial growth factor (VEGF) is one of the most important angiogenic factors. Several solid tumors produce substantial amounts of VEGF, which stimulates proliferation and the migration of ednothelial cells, therby inducing neovasculization by a paracrine mechanism. To evaluate the prognostic roles of angiogenesis and VEGF expression in patients with non-small cell lung cancer, the relationship between VEGF expression in tumor tissues, the clinicopathologic features and the overall survival rate were analysed. METHODS: Sixty-nine resected primary non-small cell lung cancer specimens were evaluated. The pareffinembedded tumor tissues were stained by anti-VEGF polyclonal antibodies using an immunohistochemical method to assess VEGF expression. RESULTS: In Forty-one patients (59%), the VEGF antigen was expressed weakly in their tumor tissue, whereas in twenty-eight patients (41%) the VEGF antigen was expressed strongly. The median survival time of the weak VEGF expression group was 24 months, and that of the strong VEGF expression group was 19 months. The three year-survival rates were 35%, 33%, respectively. The survival difference between both groups was not statistically significnat. CONCLUSION: Although results were not statistically significant, the strong expression group tended to poorer prognosis than weak expression group.
