In order to compare the clinical results of Automated Lamellar Keratoplasty with Laser Assisted In Situ Keratomileusis for corection of high myopia, the effects of the procedure on 9 patients(10eyes) following ALK and 14 patients(15 eyes) following LASIK who were followed up at least 6 months were analyzed retrospectively. Mean preoperative spherical equivalent(S.E) was -17.32D(-11.50D~-22.50D) in ALK group and -16.05D(-12.00D~-24.00D) in LASIK group, while mean postoperative S.E was -3.19D at 1 week, -3.50D at 1 month, -4.12D at 3 months, -3.83D at 6 months in ALK group and +2.10D at 1 week, 0.70D at 1 months, -0.10D at 3 months, -0.58D at 6 months in LASIK group. Mean preoperative uncorrected visual acuity was 0.03 in ALK group and 0.04 in LASIK group. At postoperative 6 months, mean uncorrected visual acuity was improved to 0.18 in ALK group and 0.52 in LASIK group. The percentages of patients achieving correction within +/-1.00D at 6 months were 20% in ALK group and 47% in LASIK group. Postoperative cylindrical change was not significant in each group(p>0.05) and also best corrected visual acuity did not show statiscally significant changes in each group(p>0.05). The complications included folds of corneal flap, increased IOP, night halo, and corneal haze. In conclusion, ALK, when performed for high myopia with Ruiz normogram, resulted in undercorrection. LASIK seems to be much more predictable and accurate than ALK in high myopia.

Cytologic findings of pleural effusion in three cases of rhabdomyosarcoma are reported. Case 1 was a pleomorphic rhabdomyosarcoma which had devoped at the chest wall of an elderly male patient and caused pleural effusion. The cytologic features were consistent with pleomorphic rhabdomyosarcoma, that was, showing loose clusters, cellular pleomorphism, and abundant finely vesicular cytoplasm. Cases 2 and 3 were embryonal rhabdomyosarcomas in young adults. Primary site was the oral cavity in case 1, but unknown in case 2 and case 3. The effusion cytology was similar in these cases. Clustered or isolated small round cells with hyperchromatic nuclei and scanty cytoplasm were smeared. The cohesiveness of tumor cells was weak and the cells did not show linear arrangement or nuclear molding. Effusion cytology in a sarcoma patient would be diagnostic when the primary site and the type of sarcoma were already known.

Yonsei University College of Medicine, Seoul, Korea Maffucci's syndrome is characterized by dysccondroplasia with hemangiomata. Since Angelo Maffucci (1881) first described this entity, 105 cases and some more were reported in the literature till 1976. We recently observed a patient suffering from this disorder. The patient is 21 year-old girl, who has multiple hemangiomes on her right foot, right buttock, left wrist and enchondromas on both proximal phalanx, distal phalanx of both great toes and proximal, middle phalanx of right second toe. The disease started at age of 11 and these lesions grew rapidly last 3 years. The diagnosis was based on clinical, radiological and histological findings. Because of its rarity, we report it with brief review of literature.

Studies on epidemiological aspects of contact dermatitis have been published in recent years since the introduction of standardized method of patch test.However, most previous epidemiologic reports studied patients with allergic contact dermatitis in hospitals with patcb testing. Such data are not directly applicable to the population at large. Very recentiy there are a few reports ahout rates of exposure and patch test reactivity to certain antigens in a general population. which is difficult to be applicable in a developing country at present. With regard to this, we have tried to analyze the contact dermatitis questionaire containing various items of common causative agents producting contact dermatitis (for example, metals, cosmetics, plants, medicaments and rubber etc.) for the detection of past contact dermatitis histories in a total new dermatologic outpatients. A11 2258 dermatologic outpatients entered this study including 303 contact dermatitis patients (allergic contact dermatitis, primary irritant dermatitis and housewife eczema). We also analyzed the patch test results of 107 patients with suggesting contact dermatitis who visited our hospital at the same period of collecting questionaires. The study results were as follows. 1. Positive rate of each item of the questionaire (No. of said Yes/ No. of responders) was metals, 10.4% cosmetics, 31.8%, plants, 18.2%; medicaments, 12.4%; rubber, 5.8%; and others, 11.7%. 2. The most common all regens of the patch test positive reactions were nickel sulfate (9.3%), fragrance mix(9.3%), formaldehyde(6.5%), potassium dichromate (5.6%), neomycin sulfate (5.6%), balsam of Peru (4.7%), cobalt chloride(3.7%), wood tar(3.7%) and paraphenylene diamine (2.8%) in order of frequency. And the patch test positive rate of commercial cosmetic products was 10.3%. In conclusion, cosmetics, medicaments, metals, plants and rarely rubber are found the most common etiologic agents of contact dermatitis in this study. The reasons and back-ground of the results were also discussed in various aspects.

Eighty cases of malignant effusion were cytologically studied to elucidate the incidence of primary tumor site and cytologic characteristics of each tumor types. Eighty fluid specimens were composed of 43 ascitic, 35 pleural, and 2 pericardial effusion and primary tumor site had been confirmed by histology. The frequent primary sites were stomach (22 cases, 28%), lung (21 cases, 26%), ovary (11 cases, 14%), liver (7 cases, 9%), and breast (4 cases, 5%). The principal malignant tumors were adenocarcinoma (56 cases, 70%), squamous cell carcinoma (7 cases, 9%), liver cell carcinoma (7 cases, 9%), small cell carcinoma (4 cases, 5%), and non-Hodgkin's lymphoma (4 cases, 5%). The distinctive cytologic findings according to primary tumor types were as follows; the gastric adenocarcinomas were mainly characterized by isolated cells and irregular clusters sometimes with signet ring cells. Papillary serous cystadenocarcinoma of ovary showed frequently papillary clusters and occasional psammoma bodies. Breast carcinoma of ductal type showed cell balls with smooth margins. Colonic adenocarcinoma showed rather irregular clusters o palisading pattern of cylindrical cells. Metastatic squamous cell carcinoma, liver cell carcinoma, small cell carcinoma, and non-Hodgkin's lymphoma showed also characteristic features. These findings indicate that the cytological features observed in the great majority of malignant effusion are similar to those of primary tumor types, which are very helpful to indentify the primary tumor site.

Spontaneous Subcapsular hematoma of the kidney is relatively uncommon. Although several cases have been recorded in the literature, the diagnosis was seldom made preoperatively. Selective renal angiography provide an excellent means of diagnosing this lesion prior to surgery. Case I: A 37 years male was admitted with the right flank pain and hematuria. Excretory urogram showed moderate hydronephrosis and a cystic shadow compressing upper calices. Selective renal angiography showed strip-like curvilinear capsular density outside the nonopacifying mass. By exploration, blood clots, about 300 c. c., between renal parenchyma and renal capsule was evacuated. The cause of the hematoma is uncertain whether it is from ruptured aneurysm or due to hydronephrosis. Case II : A 54-year-old woman was hospitalized with right flank discomfortness and mild fever. Intravenous pyelogram revealed increased size of the right kidney and angiogram demonstrated the compressed and flattened renal parenchyma by a nonopacifying mass and renal capsule on the outer margin of the mass. Blood clots, about 200 c.c., inside the renal capsule which compressed renal parenchyma was evacuated.

Both sodium fluorescein[FL] and indocyanine green[ICG] were used for fundus angiography. Recently, these were also used during cataract surgery for enhancement of capsular visualization in white mature or hypermature cataract. So, ICG and FL may influence corneal endothelial function if left in anterior chamber. To evaluate the effect of intracameral FL or ICG on corneal endothelial function, rabbit corneas were isolated &mounted in the in-vitro specular microscope for endothelial perfusion. Experimental corneas were perfused with different concentrations of FL or ICG. Control corneas were perfused with glutathione-bicarbonate Ringer solution[GBR]. Corneal thickness was measured every 15 minutes during the perfusion and corneal swelling rates were calculated. Corneal endothelial permeability[Pa c] was measured according to the method of Watsky et al. The corneas perfused with FL, 2.5% deswelled probably due to high osmolarity. Swelling rates of corneas perfused with 1% and 0.5% FL did not differ significantly from control[p>0.05]. The corneas perfused with 0.01%, 0.005%, 0.002%, and 0.001% ICG swelled significantly[p<0.05], while swelling rates of the corneas with 0.0005%, and 0.0001% ICG did not differ from control[p>0.05]. Pa c in corneas perfused with ICG, 0.005% increased markedly compared to control while corneas perfused with FL, 1% showed decreased permeability. The results of this study showed that FL did not affect endothelial function of rabbit cornea in relatively high concentrations while ICG affected endothelial function even in lower concentrations. With respect to clinical use of intracameral ICG, close attention must be paid.

The immunocompetence is important not only to kill the neoplastic cells but also to keep the neoplastic cells from growing further. T lymphocyte is plays the most important role in maintaining the tumor immunity efficiently. T lymphocyte has its specific functions depending in the subset of T lymphocytes. The author analyzed the T lymphocyte subsets in 31 brain tumor patients using anti-CD3, anti-CD4, anti-CD8 monoclonal antibodies and flow cytometry to determine the immunological status of brain tumor patients. All CD3, CD4 and CD8 subsets were reduced in both benign and malignant brain tumor patients but more signigicantly reduced in malignant tumor group. But in benign tumor group, the subtypes of T lymphocytes were not so different from those of normal healthy controls except the pituitary tumor patients, who showed the significant decrease in all the subtypes. In malignant tumor group, each subtype was signigicantly reduced and CD8 subtypes was markedly reduced in metastatic tumor patients, These analyses were considered to have the possibility to be contributable to planning the further immunotherapy and also the possibility to moniter the brain tumor patients clinically.

To investigate the factors affecting the visual outcome after otherwise successful retinal reattachment surgery in rhegmatogenous retinal detachment involving macula, we performed a retrospective surgvey on 170 eyes encountered properly for this study. Preoperative variables used in this series included age of patients, duration of macular detachment, preoperative visual acuity, extent of detached retina, distance between breaks, and number, shape and location of breaks. We achieved visual acuities of 20/50 or better in 49% (83 of 170 eyes) after retinal reattachment surgery. Factors related to the favorable visual outcome (20/50 or better) were macular detachment lasting less than one month, preoperative visual acuities of 20/200 or better, extent of retinal detachment of 3Q or less, and detachment with tears located at or anterior to the equator. There was no relationship between the visual outcome and the type and the number of the breaks. Of all these variables, preoperative visual acuity has the closest correlation with the final visual results after anatomically successful reattachment surgery.
