BACKGROUND: Cytokeratins were subdivided into 20 different cytokeratins. It is known that cytokeratin 19 is particularly abundant in carcinoma of the lung. METHOD: A sandwich enzyme-linked immunosorbent assay called CYFRA 21-1, combining two monoclonal antibodies directed specifically aganist cytokeratin 19 was done by ES-300(Boehringer Mannheim, Germany). We investigated the diagnostic value of the new tumor marker CYFRA 21-1 in lung cancer in comparison to carcinoembryonic antigen(CEA) and neuron specific enolase(NSE) in the pilot study on 39 serum samples from lung cancer (17 squamous cell cancer, 11 adenocarcinoma, 11 small cell carcinoma) and 51 benign lung diseases and 41 normal healthy persons. RESULTS: Postulating a specificity 95% versus benign lung disease and healthy group, the diagnostic sensitivity of CYFRA 21-1 in lung cnacer independent of histologic type was 43.6% whereas CEA was 48.7% and NSE was 30.8%. The diagnostic sensitivity is increased to 69.2% by combining CYFRA 21-1 with CEA. Classifying the lung carcinomas following their histologic type, squamous cell carcinomas proved to possess the highest CYFRA 21-1 sensitivity(CYFRA 21-1 47.1%, CEA 23.5%, NSE 11.8%) and the combination with CEA 52.9% could not markedly increase the number of true-positive test results. In adenocarcinoma, CEA possessed the highest sensitivity (81.8%) whereas CYFRA 21-1 was 45.5% and NSE was 9.1%. In small cell carcinoma of lung, NSE possessed the highest sensitivity(81.8%) whereas CYFRA 21-1 was 36.4% and CEA was 54.5%. CONCLUSION: This study indicates that CYFRA 21-1 has a potential as a new marker for squamous cell lung cancer. If histologic type is unknown at the time of primary diagnosis. the combined determination of CYFRA 21-1 and CEA showed the best discrimination between benign and malignant lung disease.

Primary cardiac tumors in infancy and childhood are rare, with fibromas being the second most common tumor after rhabdomyomas. Although cardiac fibromas are characteristically benign intramural tumors, they may exhibit exhibit expansile growth resulting in obstruction, valvular dysfunction, as well as other problems so early diagnosis and successful surgical excision are important. We report a case of cardiac fibroma in a 2 month-old male infant. He presented with generalized cyanosis from birth. Echocardiography showed oval round large mass filing the right atrium and ventricle which infiltrated into the lateral wall of the ventricle. Partial excision of the tumor was done after another echocardiogram showed a pericardial effusion and restriction of blood flow to the right ventricle due to the tumor. The resected tumor was ovoid, gray-tan, slightly firm and measuring 5x3x2.5 cm. Histologically, the tumor was composed of spindle-shaped fibroblasts and hyalinized fibrous tissue interdigitating with the surrounding myocardium.

Between December 1993 and March 1996, 75 patients had undergone subannular procedures in mitral valve reconstruction. Their mean age was 45 years and they consisted of 28 males and 47 females. The cause of mitral disease in 75 patients were classified as follow : 29 cases were degenerative, 40 cases were rheumatic, 3 cases were congenital, 2 cases were infectious and 1 case was ischemic. Average number of mitral anatomical lesion per patient was 3.1 and we used average 1.5 procedures on subannular structure in mitral valve per patient. Subannular procedures were chordae shortening 21, chordae transfer 22, new chordae formation 20, papillary muscle splitting 33, shortening of papillary muscle 2. Intraoperative transesophageal echocardiography was carried out for providing an immediate and accurate assessment of the adequacy of the reconstruction. There was no operative death. Patients have been followed up from 2 to 29months, mean 12.5. There were two failures that necessitated reoperation. The mean functional class(NYHA) was 3.19 preoperative and improved to 1.12. postoperatively. After mitral valve repair, the patients were improved hemodynamic, echocardiographic data. In conclusion, subannular procedure in mitral valve repair when feasible is stable and safe with a low prevalence of reoperation.

Management of urologic patients is being gradually but dramatically altered with new advances in technical innovation and refinements of interventional uroradiology. The broadening of indications for percutaneous nephrostomy became possible only after it was learned that it is a safe and effective means of establishing access to the renal collecting system. Percutaneous stone extraction (Nephrolithotomy) and Endopyelotomy are now well established procedures. These techniques have clear advantages over the surgical treatment for the same conditions and will increase the quality of patient care and reduce health care cost.
