Journal of the Korean Ophthalmological Society 1959;2(1):102-105
The author operated 34 cases of pterygia by Newton's method, wihich combined Mc Raynold's transplantation with limbal incision, in these 34 case, 4 cases were recurred, and in other 2 cases, a few vessels only found on the operated area of the cornea. Among these 6 cases, one had trachoma, 3 had chronic cat conjunctivitis. Auther thinks that the chronic inflammation such as trachoma or chronic conjunctivitis is very important factor in the recurrence of pterygia. This fact also encourages the author who believes that the inflammation is rather more important factor in the etiology of the pterygia than the degensration.

5.Advantages of Scorpion Suture Passer and 70 Degrees Arthroscope in Arthroscopic Bankart Repair: Usefulness for Inferior Labral Repair.
Clinics in Shoulder and Elbow 2017;20(4):201-207
BACKGROUND: The blunted tip of a reusable with multiple uses can cause problems with the passing procedure in arthroscopic Bankart repair. This study assessed the advantage of Scorpion with a 70° arthroscope in arthroscopic Bankart repair compared to hook typed suture passer. METHODS: Scorpion in 19 patients, the hook type suture passer (conventional group) in 18 patients were used. All patients underwent the same procedure except for the type of suture passer used. Another different point of the procedure were telescopes and the number of portals used; three arthroscopic portals (posterior, anterorsuperiorlateral, and mid-anterior) and a 30° arthroscope in the conventional group, but two portals and a 70° arthroscope as well as the 30° one in the Scorpion group. The surgery time and the surgical complications including an iatrogenic axillary nerve injury were recorded. RESULTS: The Scorpion group showed a significant decrease in surgery time compared to the conventional group. In contrast to the conventional group, Scorpion provided an easy estimation of the exit of suture passing, no iatrogenic labral injury during the passing procedure with straight movement and the sharp tip of the knife installed. Iatrogenic supraspinatus injuries could be avoided when making an accessory anteosuperiorlateral portal due to the 70° arthroscope. CONCLUSIONS: In arthroscopic Bankart repair, the use of the Scorpion suture passer and a 70° arthroscope can reduce the surgery time, avoid unnecessary supraspinatus injury, and avoid iatrogenic axillary nerve damage through the relatively easy and precise suture passing and saving of the anterosuperior portal.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

The mucoepidermoid carcinoma is a rare tumor in the lung. A case of bronchial mucoepidermoid carcinoma diagnosed by fine needle aspiration cytology is presented. The smear showed many intermediate cells with occasional mucus-secreting cells. Malignant squamous cells were not present. The cellular arrangement of intermediate cells was overlapping and grouped in ball-like fashion. These cytologic features are unique for diagnosis of this tumor.

Hepatocellular carcinoma (HCC) is malignant tumor frequently occurring in Koreans. There have been few reports regarding the cytologic findings of fine needle aspiration (FNA) of HCC. Most have suggested a diagnostic problem in the cytology distinguishing HCC from some benign hepatic lesions-for example, a regeneration nodule in cirrhosis and liver cell adenoma. In spite of its high frequency in Korea, no cytologic study has been reported, concerning the FNA of HCC. In an attempt to achieve cytologic criteria for the diagnosis of HCC, the authors studied retrospectively cytopathologic findings of 247 cases of HCC. These cases were confirmed either by histologic examination including lobectomy, biopsy, or cell block materiai, or, when tissue diagnosis was unavailable, by a high serum alpha-fetoprotein level (over 400 l. U.). All aspiration smears were stained by the Papanicolaou method. In each case, the smears were analyzed for cell patterns and various cytomorphology of the tumor cells. The smear background was assessed for the presence of tumor cell necrosis and inflammatory components and compared to that of metastatic carcinomas. The cell patterns were classified as trabecular, acinar, dispersed, and irregular. The cytologic parameters analyzed included the degree of nuclear atypia and the presence of mitoses, intranuclear cytoplasmic inclusions, nucleolar prominency, endotheiial lining, multinucleated giant cells, eosinophiic globules, bile, and Mallory body.Most of the FNA of HCC showed markedly cellular smears. The tumor cells were most frequently arranged in a trabecular pattern (80.3%). The irregular (12.6%), the acinar (5.5%), and the dispersed patterns (1.7%) followed in decreasing frequency. Individual hepatoma cells were larger than normal liver cells. However, they had morphologic features characteristic of the hepatic cells: the cells were round or polygonal, their cytoplasm was abundant and granular with eosinophilic or amphophilic stainability, and their nuclei were round to oval, located centrally, and tended to have prominent nucleoli. Anaplasia and pleomorphism of tumor cells were generally mild to moderate. These findings existed even in very well differentiated cases. Mitotic figures were present in about 85% of the cases. Prominent nucleoli were observed only in about half the cases. The frequency of other cytologic features was as follows: intranuclear cytoplasmic inclusion in 86.8%; endothelial lining in 56.1%: bile in 19.8%; and giant cells in 60.1%. Clear cells were often present in11.7%, Most aspiration smears of HCC displayed clean background without necrosis or inflammatory material in contrast to the dirty, necrotic background of metastatic cancers and cholangiocarcinomas. Based on the above mentioned features, it is suqqested that the cytologic critieria most important for the diagnosis of HCC include a markedly cellular smear, trabecular pattern, hepatocytoid appearance of tumor cells, endothelial lining, the presence of bile, giant cells, intranuclear cytoplasmic inclusions, and prominent nucleoli, Among these, trabecular pattern, endothelial lining, giant cells and clean smear background are points to be considered in differentiating HCC from metastatic and cholangiocellular carcinoma.

PURPOSE: Lymphoma is considered when multiple, nonnecrotic lymph nodes are present in the superficial and deep lymphatic chains, especially if they are large and bilateral, on CT scan. It is reported that combined nodal and extranodal presentation of HD is uncommon. However, we found central low density in involved lymph node of NHL, and combined nodal and extranodal disease in HD, not infrequently. The purpose of this study is to ascertain whether our findings may be characteristics of NHL and HD. MATERIALS AND METHODS: CT findings with contrast enhancement were reviewed in 23 patients with untreated neck lymphoma:18 NHL and 5 HD. The followings were analyzed in each case: nodal or extranodal involvement; unilateral or bilateral involvement; presence or absence of central low density with peripheral enhancement in nodal lesion ;infiltration into adjacent structures. Nodal and extranodal lesions were confirmed by pathologic studies. RESULTS: Of 18 patients with NHL, nine cases had nodal disease and the rest had combined nodal and extranodal disease. Lymphadenopathy was bilateral in ten cases and unilateral in eight. Five cases with HD were composed of three combined nodal and extranodal diseases and two nodal diseases. Central low density of involved lymph node was shown in eight cases of 18 NHL and in one case of five HD. CONCLUSION: Central low density with peripheral enhancement was not uncommon in NHL, in contrast to HD. Hence, it is suggested that in case of nodal necrosis, NHL be also considered, besides tuberculous lymphadenitis and metastatic lymphadenopathy. It is not considered that nodal or extranodal disease, and unilateral or bilateral involvement are of high significance in differentiation of NHL from HD.
