A case of pulmonary alveolar proteinosis is reported. Most of the alveolar spaces were filled with amorphous deep eosinohilic material which revealed strong positive reaction to periodic acid-Schiff staining. Electron microscopic observation of this material showed numerous lamellar bodies in the alveolar spaces and cytoplasms of alveolar macrophages. A part of them were concentric multilamellated type A lamellar bodies and the other were finger printlike type B bodies. Combined type A and type B lamellar bodies were rarely present. From the above features it is suggested that both type A and B lamellar bodies could be transformed one another and those lamellar bodies may be originated from pulmonary surfactant.

Cutaneous leishmaniasis (oriental sore) is usually a self-limited infection of the skin caused by the protozoan Leishmania tropica. The disease is endemic to the Mediterranean, Asia, Africa, and the Middle East. It has been seen in this country among many Korean technical experts and labourers working in the endemic areas of the disease. Our patient had acquired cutaneous leishmaniasis in Saudi Arabia and it had remained active for six months. He had been treated with antimony and metronidazole but failed because of severe side effects. And then we treated the patient witb cryosurgery and the skin lesions were followed by resolution with cosmetically acceptable scar in 4 months. The brief review of literature on the treatment of cutaneous leishmaniasis was undertaken.

We performed surgery for correction of abnormal head turn in 10 patients with congenital nystagmus. For 3 patients with a head turn of 30 degrees, a 40% augmented modified kestenbaum operation was performed. For 4 patients with a head turn of 45 degrees, a 40% augmented modified kestenbaum operation combined with a 3 - 4 mm recession of conjunctival and subconjunctival tissues was performed. Finally, for 3 patients with a head turn of 60 degrees, a 60% augmented modified kestenbaum procedure combined with a 3 - 4 mm recession of conjunctival and subconjunctival tissues was performed. At the final follow-up visit(averaging 5.9 months), 7 patients showed complete corrections of previous head turn and 3 patients showed a small residual head turn of less than 10 degrees to the same side of the preoperative head turn. The average amount of correction we obtained from the surgery described above were 26.7, 42.5 and 56.7 degrees for the patients who had had a preoperative head turn of 30, 45 and 60 degrees respectively. Among the 10 patients, 4 showed no change in corrected visual acuity, but 6 showed increased corrected visual acuity by over 1 Snellen line. From the above results, we concluded that if recession procedure of the conjunctival and subconjunctival tissues was combined with augmented modified Kestenbaum procedure, its effect for correction of abnormal head turn in a patient with congenital nystagmus could be enhanced.

OBJECTIVES: Careful evaluation about mediastinal involvement is important in the management of patients with non-small cell lung cancer. Invasive staging procedure such as mediastinoscopy is advocated because of the unreliability of noninvasive staging methods such as CT, MRI. We compared differences between pre- and postoperative staging in non-small cell lung cancer without lymphadenopathy on CT scan and investigated the methods for more accurate preoperative staging. METHODS & RESULTS: 1) Records of a total of 41 patients with preoperative T1-3N0M0 non-small cell lung cancer were reviewed and the histologic types of tumors were squamous cell carcinoma in 32 cases, adenocarcinoma in 6 cases and large cell carcinoma in 3 cases. Twenty-four cases were central lesions and seventeen cases were peripheral lesions. 2) Among the 32 cases with preoperative T2, 2 cases were identified postoperatively as T3 with invasion of chest wall and among 6 cases with preoperative T1-3, 1 case was identified postoperatively as T4 with invasion of aorta and pulmonary arteries. 3) After the operation of 35 cases with T1-2, 5 cases wore N1 and 3 cases were N2 postoperatively. After the operation of 6 cases with T3, 2 cases were N1 and 3 cases were N2 postoperatively Preoperative T3 showed more intrathoracic lymph node metastases and higher N2/N1 involvement ratio than preoperative T1-2. 4) Complete surgical resections were done in 34 out of 41 cases. Incomplete resection were done in all postoperative N2 tumors. CONCLUSION: Invasive staging procedures such as mediastinoscopy should be considered in the case of preoperative T3 non-small cell lung cancer even though mediastinal lymphadenopathy is not recognized on the CT scan of the chest.

BACKGROUND: It is necessary for most effective treatment of neoplasms to detect it in early stage. For the purpose we use many screening tests currently, however, the tumor marker have many limitations as a screening test for neoplasm. Nevertheless most of Health screening centers are using CEA as a screening test for neoplasm. So, we began this study for the assessment of validity of CEA as a screening test for neoplasm. METHODS: The subjects were 4265 persons who visited Health screening center of Kyung hee Medical Center from July 1995 to June 1996. The number of elevated CEA among the subjects was 156. We evaluated the frequencies of factors known as etiologies of increased CEA. We followed up whether neoplasms were developed in normal CEA group. Through the random sampling of normal CEA group, 391 subjects were obtained for statistical analysis by SPSS/PC+. Immunoradiometric assay kit, of Eiken company was used for gauging CEA level and normal level was less than 2.4ng/ml according to manual of manufacturer. RESULTS: There was no significant difference of CEA according to sex, age. The factors that significantly affect CEA were neoplasms, chronic lung disease, liver cirrhosis. In t,his study, smoking, hypertension, diabetes mellitus, fibrocystic disease, chronic renal failure, alcohol drinking, hepatitis, peptic ulcer disease known as etiologies of elevated CEA in other studies did not show statistical significance. 9 cases of neoplasms were developed in both elevated CEA and normal CEA group during follow up. In former, 4 cases of 9 neoplasms were early stage. In latter, all cases were stage IV and inoperable. Specificity and sensitivity of CEA were each 96.5%, 50.0%. Positive & negative predictive value of CEA were each 5.8%, 99.8%. CONCLUSIONS: CEA was increased in various benign conditions and even if any neoplasm exists, CEA was not elevated in most of all in early stage. It showed high false positive rate and low sensitivity. Thus, this study showed that it was not valid to use CEA as a screening test for early detection of neoplasms.

The prognoses for the gastric cancer patients treated with total gastrectomies are known to be unsatisfactory due to the low survival rates, the high frequency of postoperative mortality or morbidity, and long-term complications such as nutritional deficiency. The authors evaluated the 5-year survival rates and analyzed the prognostic factors in 557 patients with gastric cancer who underwent total gastrectomies during the period between Jan. 1987 and Dec. 1993. The overall 5-year survival rate was 49.7%, and the survival rates according to the stage were stage Ia, 92.0%; Ib, 85.5%; II 64.1%; IIIa 55.0%; IIIb 26.5%; and stage IV, 6.3%. Postoperative mortality rate was 1.1%. By using univariate analysis to evaluate the prognostic factors, factors such as age, depth of invasion, extent of lymph node metastasis (according to the Japanese rule), number of involved nodes, lymph node ratio, distant metastasis (peritoneal and/or hepatic), size of the tumor, gross type, histological type, the surgical curability and the TNM stage were found to be related with the survival of the patients. In a multivariate analysis using 11 variables, the TNM stage was the single most significant prognostic factor. Besides the TNM, depth of invasion (ratio of risk (R.R)=1.50), extent of lymph node metastasis (R.R=1.83), number of involved nodes (R.R=1.64), lymph node ratio (R.R=1.91), and peritoneal metastasis (R.R=3.11) were found to be independent prognostic factors influencing survival. It was thought that the radicality of surgery could be reflected in the number of removed nodes per specimen. In this study, the average number of removed nodes was 42.3 per case. Hence, it may be said that adequate lymphadenectomy was performed for almost all the grossly curable cancers. The 5-year survival rate in stage IV patients with tertiary node (N3) metastasis and no peritoneal or hepatic metastasis was 16.8%; in patients with peritoneal or hepatic metastasis, the survival rate was 0%. There was a significant survival difference between these two groups (p<0.05). This result suggests that the tertiary node metastasis is a potentially curable factor, and that it should be classified differently in the current TNM system. In conclusion, the overall survival rates in the patients treated with total gastrectomies were favorable compared with the results in other reports. Depth of invasion, extent of lymph node metastasis, number of involved nodes, lymph node ratio were important prognostic factors for survival after a total gastrectomy. The current TNM staging system appears to be a reasonable one, except that the probable curability of tertiary node metastasis may need to be taken into consideration.

Changes of bone turnover with aging are responsible for bone loss and play a major role in osteoporosis. Among the early postmenopausal women, as are known by previous study, there are about 35% ""fast bone losers and bone turnover is more uncoupled in osteoporotic group than in normal control. So, early detection of such fast losers"" and women who have high turnover rate is important to prevent postmenopausal osteoporosis and spontaneous fracture. Dual-energy X-Ray absorptiometry (DEXA), however, cannot reflect current bone loss because changes in bone mineral density (BMD) are only seen after 1 or more years of bone densities declining. In this study, we have measured a battery of new sensitive and specific markers of bone turnover which reflect current bone loss. To investigate the changing pattern of those markers, 674 healthy women including 451 postmenopausal women were classified, according to their menopausal period (less than 5 years, 5-10 years, more than 10 years). Bone formation was assessed by serum osteocalcin (OC), bone-specific alkaline phosphatase (BSAP) and bone resorption by the urinary excretion of deoxypyridinoline (DPD), cross-linked N-telopeptide of type I collagen (NTX). All Biochemical markers, except OC, significantly increased after menopause (p < 0.05). NTX and BSAP remained elevated after 10 years of menopause. These data indicated that the overall rates of both bone formation and bone tesorption increased after menopause and remained high in elderly women.

Combined resection of the spleen during total gastrectomy for gastric cancer is usually performed to remove the lymph nodes adequately and thereby achieving surgical radicality. However there is still controversy whether a total gastrectomy combined with a splenectomy can improve the survival rate. The authors retrospectively analyzed 557 gastric cancer patients, who underwent total gastrectomy at the Department of Surgery of Yonsei University during the 7-year period between 1987 and 1993, in order to investigate the influence of combined resection of the spleen upon the patients' survival. The patients were followed until March 1996, and the rate of follow up was 90.6%. The number of cases in which the spleen was saved was 101(the spleen conservation group, SC) and the number of cases in which the spleen was resected was 431(the spleen resection group, SR). Twenty-five cases were excluded due to incomplete data. Among the 431 cases for whom splenectomy was done, 343 were cases in which spleen was the only organ removed other than the stomach (SOR). For the other 88 cases, at least 1 more organs were resected along with the stomach and the spleen(Sp combined). There were no significant differences in the clinical characteristics such as age, sex ratio, tumor size, depth of invasion, nodal stage, TNM stage and histological type between SC and SOR group. In terms of the nodes removed during operation, there was significant difference between the SC and the SOR groups. Also, the Sp combined group showed significant differences in terms of tumor size, depth, nodal stage, TNM stage, and removed nodes. The overall 5-yr survival rate for the spleen conservation group(SC, N=101) was 61.2% and the survival rates according to TNM stage were 94.0% for stage I, 94.1% for stage II, 30.0% for III, and 0.0% for stage IV. The overall 5-yr survival rate for the 343 patients with splenectomy(SOR) was 51.9%, and the survival rates according to TNM stages were 88.7% for stage I, 57.0% for II, 44.0% for III, and 10.8% for stage IV. The overall 5-yr survival rate for the 431 patients with splenectomies or with splenectomies and multiple organ resection(SR) was 48.2%, and the survival rates according to the stages were 88.2% for stage I, 60.2% for II, 41.5% for III, and 6.8% for stage IV. The overall 5-yr survival rate was higher in SC group than in the SOR or the SR groups, but there was no statistical significance to this difference (p>0.05). In a compared according to the TNM stage, the SC group showed better survival rates in the relatively early stages (I, II) than the SOR or the SR groups did; in advanced stages (III, IV), the SOR and the SR groups showed better survival rates than the SC group. However, there was no statistically significant differences in survival among the three groups. These results suggest that during a total gastrectomy, it may be better to save the spleen in early stages of gastric cancer and that it may be better to resect the spleen for adquate lymphadenectomy in grossly advanced stages. To identify statistical difference in survival, it might be necessary to perform a randomized prospective study.
