A Case of Adenocarcinoma Presenting a Solitary Pulmonary Nodule That Showed No Growth Over 4 Years / 결핵및호흡기질환

A case of 51-year-old woman with a malignant solitary pulmonary nodule (SPN) that exhibited no growth over a period of 4 years is reported. Surgical wedge resection revealed an adenocarcinoma upon intra-operative frozen ex-amination. The operation was completed with a right upper lobectomy and complete lymphadenectomy. The authors recommend an early surgical procedure for any SPNs due to risk factors for developing lung cancer.

Bacteriologic Study and Prophylactic Antibiotics in the Acute and Complicated Appendicitis

This prospective study was performed to determine the effective antibiotics for use in treating acute appendicitis patients during the perioperative period. To identify the sensitive antibiotics, the peritoneal fluid was cultured during operation. Also, wound infection was defined as pus or serous discharge in the wound or when we opened the wound under suspicious of a wound problem. The results were obtained as follows: 1) A total of 138 cases treated during the two years from January 1995 to December 1996 were examined; 84 of them (60.87%) were found to have positive peritoneal fluid cultures, of which 29 (34.52%) were monomicrobial and 55 (65.48%) were polymicrobial. 2) The most common species were Escherichia coli (73.81%), Bacteroides (32.14%), Klebsiella (16.67%), Pseudomonas (9.52%), and Streptococcus (9.52%). 3) In the sensitivity test, the most sensitive drugs were aminoglycosides and cefotaxime. 4) Infectious complications, which developed in 27 (19.6%) patients, were wound infection and intraabdominal abscess. 5) The average length of stay for all patients 9.9 days (range: 3 to 32 days). 6) The common organisms curtured from the complication cases were E. coli and Bacteroides.

Study of the Relation between Rreduced E-cadherin Expression and Known Prognostic Factors in Breast Cancer

Breast Cancer in women poses a problem, and it can be difficult at times to evaluate the possibility of the cancer's recurrence in node negative early cancer. Reliable prognostic markers are needed in breast-cancer management to help clinicians identify patient with high risk of recurrence and arrive at more rational decisions for proper treatment. E-cadherin is a glycoprotein that mediates Ca2 -dependent cell-cell adhesion and maintenance of the epithelial cell phenotype. It has been implicated as an invasion-suppressing protein in experimental systems and in human tumors, and alterations in the cadherin function have been implicated in tumor progression in a number of adenocarcinomas. In this study, the expression of E-cadherin was reduced in 35.3% of the case reviewed(12/34), and we could find no clinical relation between the known prognostic factors except tumor stage(p<0.05), and the degree of E-cadherin expression.

Lipoma of the parotid gland

We report two cases of lipoma of the parotid gland which present as a non-tender, freely movable and intraparotid mass. Lipomas are common soft tissue neoplasms but found very rarely in the parotid gland, and so are often not considered in the initial differential diagnosis of parotid gland tumor. We believe that these tumors are cured by simple excision, and thus superficial parotidectomy is enough for treatment.
