Adenoid cystic carcinoma arising from the submucosal glands of the trachea and bronchial tree is rare. The histopathology and natural history of bronchial adenoid cystic carcinoma have been well documented, but detailed descriptions of its cytomorphology are few. We report a case of primary bronchial adenoid cystic carcinoma in a 20-year-old female, diagnosed by bronchial brushing cytology. The cytologic specimens showed large clusters of small cells arranged around cystlike spaces containing globular basophilic material.

Localized or solitary fibrous tumor (SFT) of the pleura has been classified as a type of mesothelioma, arising from the submesothelial connective tissue cells. The preoperative diagnosis of the tumor at the cytologic or histologic level is very important for the proper handling of the lesion. This preoperative diagnosis is now possible by means of the advance in the transthoracic fine needle aspiration biopsy (FNA) techniques and in the very experience of the cytopathologists. We describe FNA cytologic feature of two cases of SFT arising from the pleura. Cytologic, histologic, immunohistochemical, and electron microscopic characteristics of pleural SFT are discussed. The tumor cells of SFT are spindle or oval in shape with a variable amount of cytoplasm. They are arranged in irregular trabeculae intimately ass- ociated with capillaries. A unique cytologic feature observed in this tumor is that thick, eosinophilic, amorphous collagen bundles are scattered between tumor cells

This experimental study was conducted to evaluate the effect of indomethacin and methylprednisolone on PAN-induced nephrosis in rats. Sprague-Dawley rats weighing 150~200gm were used and divided into controls, group I (PAN intraperitoneally), group II(PAN intraperitoneally, followed by indomethacin peritoneally for 12 days), group III (PAN intraperitoneally, followed by methylprednisolone peritoneally for 12 days) and group IV (PAN intraperitoneally, followed by cyclosporin subcutaneously for 12 days). Twenty four-hour urinary protein excretion was measured on day 0, 5, 10 and 17. On the 17th day, rats were sacrificed for the determination of total serum protein, albumin and cholesterol levels. Foot process widths of glomerular epithelial cells were measured, and anionic sites of lamina rara externa were determined by using PEI as cationic probes. The following results were obtained. Twenty four-hour urinary protein excretion (mg/day) of group I was significantly increased to 455.7+/-188.8 on the 5th day compared to 15.2+/-3.7 on day 0 (p<0.01), and increased gradulally to 525.6+/-203.5 on the 10th day, then decreased to 280.6+/-25.2 on the 17th day. In group III, 24 hr urinary protein excretion on 17 th day (180.7+/-64.5) was significantly lower than that of group I (280.6+/-25.2). Total serum protein of group III was significantly lower than that of group I, and serum albumin and cholesterol did not show any significant difference among Group I, II, III and IV. Foot process widths (nm) of glomerular epithelial cells in group I, II, III and IV were 409.5+/-15.2, 387.8+/-49.2, 279.9+/-36.9 and 398.3+/-38.3, respectively. And the value of group of group III was significantly lower than that of group I (p<0.01). The number of anionic sites per 1micrometer length of glomerular basement membrane in Group I, II, III and IV were 10.3+/-1.3, 10.1+/-1.6, 12.5+/-1.5and 10.2+/-1.5, respectively. And the value of group III was significantly lower than that of group I (P<0.01). In conclusion, cyclosporin and indomethacin did not show any significant effect on PAN nephrosis in rat. However, methylprednisolone reduced the urinary protein excretion and showed significant recovery of foot process widths and number of anionic sites of glomerular basement membrane.

A statistical analysis of the diagnostic value for 244 aspiration biopsy cytology(ABC) among a total 1,043 cases from various sites was performed. ABC, using diagnostic terminology similar to that of a surgical pathology reports, was compared to the final tissue diagnosis. For the entire series, a sensitivity of 91.8%, a specificity of 99.3%, a positive predictive value of 98.9%, a negative predictive value of 94.8%, and an efficacy of the test of 96.3% were shown. There were 8 false negative and 1 false positive diagnosis. The diagnostic accuracy was 89.8%. Those results indicate that the ABC is a considerably highly accurate procedure that should be routinely employed.

Glycogen-rich clear cell carcinoma of the breast is very rare(l -3% of breast cancer). It is defined as a tumor composed of more than 50% of optically clear, neoplastic cells, characterized by centrally located nuclei and abundant cytoplasm, being positive for periodic acid Schiff(PAS) and negative for periodic acid Schiff after diastase(D-PAS) treatment. In the absence of intraductal or in situ lobular carcinoma component, metastatic clear cell carcinomas of other organs should be considered as diagnostic possibilities. We report a case of glycogen-rich clear cell carcinoma arisen in a 62-year-old woman. The tumor revealed both solid and papillary pattern with intraductal component. The neoplastic cells had clear cytoplasm, which were PAS positive, D-PAS negative, mucicarmine negative and oil red 0 negative. More than 90% of tumor cells exhibited moderate staining for anti-estrogen receptor monoclonal antibody. Flow cytometric DNA analysis revealed diploid DNA content.

BACKGROUND: Tracheal intubation for general anesthesia often leads to trauma of the airway mucosa, resulting in postoperative sore throat and hoarseness. Numerous studies have investigated the factors as contributing causes, but the influence of method of anesthesia induction and time for extubation of the endotracheal tube has not been systematically examined. The aim of this study was to establish the effects of the methods of anesthesia induction and timing of extubation on postoperative sore throat and hoarseness. METHODS: Eighty patients with ASA physical status 1 or 2 were randomly divided into four groups. Group 1 patients (n=20) recieved succinylcholine 1.0 mg/kg for intubation and early extubated ; group 2 patients (n=20) recieved succinylcholine 1.0 mg/kg for intubation and lately extubated ; group 3 patients (n=20) recieved pancuronium 0.1 mg/kg for intubation and early extubated ; group 4 patients (n=20) recieved pancuronium 0.1 mg/kg for intubation and lately extubated. All patients were interviewed 6, 24, 48, and 72 hrs after operation by an anesthesiologist in a double-blind manner. RESULTS: The incidence of sore throat at postoperative 6 and 24 hrs were decreased in group 3 compaired with group 1, 2, and 4 (p<0.05), respectively. The severity of sore throat at postoperative 6 hrs were decreased in group 3 compared with group 1, 2 and 4 (p<0.05), and that of postoperative 24 hrs were decreased in group 3 compared with group 1 and 2 (p<0.05), respectively. The severity of hoarseness at postoperative 6 hrs were decreased in group 3 compared with group 2 (p<0.05). CONCLUSIONS: We suggest that postoperative sore throat and hoarseness may be developed more when extubation was perfomed lately than early. Therefore, early extubation provide advantage in terms of reducing sore throat and hoarseness in limited cases of anesthesia.

Author analyzed 154 cases of transabdominal ultrasonography of normal adults who had normal urinalysis, no complaint of symptoms related with urinary system and no evidence of prostate disease. The maximum anteroposterior, transverse and longitudinal diameters of prostate were measured. The weight of prostate was computed using the formular for the weight of ellipsoid object (W=SGx4/3 pie r1.r2.r3, w; weight, SG; specificgravity about 1.05 gm/ml, r; radious of prostate in any dimension). The results were as follows; 1. The averagesized of prostate were 4.12±0.68 cm in transverse diameter, 3.46±0.49 cm in longitudinal diameter and 2.36±0.40cm in AP diameter. Transeverse diameter was the longest and AP diameter was the shorteset in all cases. 2. Theaverage weight of prostate in each age groups were 19.25±6.78 gm in the 3rd decade, 16.64±5.18 gm in the 4th decade, 16.28±5.31 gm in the 5th decade, 22.31±6.95gm in the 6th decade and 13.06±8.18 gm in over the 7th decade. The average weight of prostate in groups more than 50 years of age were significantly greater than youngerage groups (p<0.005). Total average weight was 18.96±6.78 gm. 3. The distribution of prostate weighting over 30gm in each groups were 14.29%(5/35) in the 3rd decade, 0%(0/34) in the 4th decade, 2.63%(1/38) in the 5th decade,20%(6/30) in the 6th decade and 23.5%(4/17) in the 7th decade.

Schwannoma is a benign encapsulated nerve sheath tumor and is histologically characterized by a mixture of Antoni type A and B tissue. A preoperative diagnosis of schwannoma by fine needle aspiration cytology or by any other means is important to preserve clinically important nerves. Therefore, it is necessary to make a specific cytological diagnosis of nerve sheath tumor. However, there are a few reports regarding cytological features of schwannoma in Korea. We experienced seven cases of solitary schwannoma and here we report their characteristic cytological features with a review of literatures. The characteristic features of schwannoma on cytology were the presence of both Antoni type A and B tissue. The cytologic findings common to all cases of schwannoma generally corresponded to the histologic findings of Antoni type A tissue, consisting of fragments of tightly cohesive fascicles with variable cellularity. Dense fibrillary substances were found, along with palisading nuclei and Verocay bodies. Individual tumor cells consisted of cohesive cells having spindle or oval nuclei, with pointed ends and indistinct cell borders. Variation in nuclear size and shape was also present. The Antoni type B consisted of scattered wavy or short spindle cells and some histiocytes and lymphocytes in the abundant myxoid background with formation of microcysts. Immunohistochemistry for S-100 protein revealed a uniformly strong positive reaction and was helpful to make more accurate diagnosis of schwannoma.
