In order to evaluate the role of cytopathologic diagnosis of sputum, bronchial washing and bronchial brushing in the diagnosis of lung cancer, we performed this study. The patients included in this study had undergone sputum, bronchial washing and brushing cytology over the 20-month period of 1985 through 1987. The total number of specimens was 5,495 of 2,242 patients, including 4,830 sputa and 665 bronchial washing and brushings. The average number of sputa and bronchial washings and brushings per case was 2.4 and 1.2 respectively. Among them, about 10% were unsatisfactory specimen, and three-fourths were negative specimens. In sputum cytology, the diagnosis of "atypical cells" was given to 3%, "suspicious for malignancy" was given to 1%, and "malignancy" was given to 13%. In bronchial washing and brushing cytology, the diagnosis of "atypical cells", "suspicious for malignancy" and malignancy" was given to 6%, 3%, and 20% respectively. The cases diagnosed as "atypical cells" in cytology were actually malignancy in 95% and 84.8% of sputum and bronchial washing and brushings respectively, and the "suspicious for malignancy" were actually malignancy in 100% in both methods. The detection rates of malignancy were 50.4% and 55.2% in sputum and bronchial washing and brushing respectively, and the specificity was 100% in both methods. The accuracy of cell typing was 92% in sputum and 89.7% in bronchial washing and brushing.

Rheumatoid arthritis is considered to be a collagen disease which mainly involves articular structures, sometimes has extraarticular manifestations. It is generally accepted now that periarticular osteoporosis develops in early phase of rheumatoid arthritis and generalized osteoporosis in late period. Of several methods of non-invasive measurement of bone mass, single photon absorptiometry was introduced by Cameron and Sorenson(1963) and it has been used for measuring bone mass by many authors with its precision, reproducibility and objective quantification. We tried to observe the quantitative changes of bone mass in rheumatoid arthritis patients with single photon absorptiometry technique. Through the study of bone densitometry in 30 rheumatoid arthritic women compared with age-matched 60 healthy controls, we obtained follow results. 1. Bone mineral density of the rheumatoid arthritis group was lower than that of the control group, but had no significant statistical difference. 2. Bone mineral density of the 40–49-year-old group and 50–59-year-old group was considerablely different in the rheumatoid arthritis group and control group. 3. Bone mineral density of the group whose rheumatoid arthritis history was over 2 year was lower than that of the group below 2 year.

An eccrine squamous syringometaplasia (ESS) is defined as a mature squamous metaplasia of the eccrine ducts. The clinical and pathological features of an ESS are presented. Syringometaplasia is a rare lesion, mostly occuring in the extremities, and as far as we know, no report on the ESS has been published in Korean literature. We experienced a case of an ESS occured in a 15 year-old male, who had a tender erythematous plaque in the right knee. The histologic examination revealed some scattered nests of metaplastic squamous epithelium in the deep dermis, associated with acute nonspecific panniculitis. The importance of the ESS is that it histologically simulates the well differentiated squamous cell carcinoma. The histopathologic findings were discussed and a brief review of the literature was made.

The medial collateral ligament is the most commonly injured ligamentous structure of the knee. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. More recently, many investigators reported that isolated medial collateral ligament injuries did well under non-operative treatment. So, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, meniscal tear and osteochondral lesion is essential. From October 1993 to April 1995, we treated 45 cases of Grade III medial collateral ligament injuries and arthroscopic finding for cruciate ligament, meniscus, bony structure were analized in these cases. The result were as follows; 1. Anterior cruciate ligament injury:37.5% in +1 degree, 42.8% in +2 degree, 86.7% in +3 degree 2. Posterior cruciate ligament injury:12.5% in +1 degree, 13.4% in +2 degree, 33.3% in +3 degree 3. Meniscal injury:12.5% in +1 degree, 21.3% in +2 degree, 33.4% in +3 degree 4. Medial capsular ligament injury was more frequent and severe in the meniscofemoral ligament than in the meniscotibial ligament, but that finding was not correlated with degree of medial instability.

Because changes in rat and dog hematological parameters according to storage conditions have been poorly documented, we sought to examine such changes. Blood analysis was performed using two hematology analyzers (ADVIA 2120i and Sysmex XN-V) after storage at room temperature and in cold storage for 5, 24, and 48 h, respectively. Interassay coefficients of variation for hematological parameters analyzed with the ADVIA 2120i and the XN-V showed similar. The levels of hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and platelet (PLT) showed significant variations with time in blood samples of rats and dogs. The leukocyte subpopulation showed high variation with storage conditions. The data for leukocyte differential counts obtained using the ADVIA 2120i, XN-V, and a manual differential counting procedure showed good agreement for neutrophils and lymphocyte counts, but monocytes, eosinophils, and basophils showed differences between the procedures. In conclusions, most rat and dog hematological parameters showed minimal changes; however, some showed high variation with storage time and temperature, especially PLT and leukocyte subpopulations. In conclusion, when performing hematological analysis in dogs and rats, it will be exactitude to analyze blood samples in fresh condition and at least within 24 h in the cold storage.

OBJECTIVE: Hysterectomy is one of the most common gynecological operations. The objective of this study is to compare the efficacy of suturing methods of vaginal cuff between laparoscopic and vaginal approach. METHODS: One hundred and sixty one cases of laparoscopic hysterectomy were devided into two groups. In group A(n=67), vaginal cuff was sutured by laparoscopic suture technique and in group B(n=94), vaginal cuff was repaired by vaginal approach. RESULTS: There were no significant differences in uterine weight, hospital stay, pre-and postoperative hemoglobin level and complications including febrile morbidity in two groups. Operation time was significantly shorter in group B(p=0.05). CONCLUSION: Transvaginal repair of vaginal cuff showed shorter duration of operation time than laparoscopic suture technique in total laparoscopichy sterectomy.

An unusual pattern of focal involvement of lymph nodes by Hodgkin's disease is described using the name Interfollicular Hodgkin's Disease. It is characterized by florid reactive follicular hyperplasia which overshadows involvement of the interfollicular zones by Hodgkin's desease. The importance of interfollicular Hodgkin's disease rests on its misdiagnosis as a benign lesion. We report a case of interfollicular Hodgkin's disease in a 34-year-old female patient in the inguinal area. The lymph nodes showed reactive follicular hyperplasia. The focal interfollicular spaces were invaded by Hodgkin's disease. The Reed-Stemberg cells stained positively with CD15 and CD30 antibody in the immunohistochemical stain. An in situ hybridization study looking for EBV was negative in these R-S cells.
