Present study describes two rare spermatic cord sarcomas. The first case is leiomyosarcoma of a 56-year-old man with 3-years' history of slowly growing hard mass in the right inguinal area, measuring 8x6x5 cm. The second case is fibrosarcoma of a 39-year-old man with 3x2 cm painless right inguinal mass. Both cases underwent radical excision of mass and orchiectomy. Clinico-pathologic characteristics of spermatic cord sarcoma are discussed with literature review.

The epidermoid cyst of the testis is a rare benign lesion with a characteristic gross and microscopic appearances. This 25 year old male who had been previously diagnosed as Klinefelter's snydrome (47/XXY) had right orchiectomy due to hard testicular nodule for a presented malignant testicular tumor. Sectioning of the testis revealed a intraparenchy matous cystic lesion, 1.5 cm in diameter, filled with cheesy white material. Histologically, stratified squamous epithelium lined the cyst. The remaining testis showed advanced tubular sclerosis and Leydig cell hyperplasia. It is necessary to submit multiple sections to rule out other histologic elements in the cyst wall or the presence of a scar. Although epidermoid cyst occurring as a solitary testicullar nodule could be regarded as a stage in the development of a teratoma, they need to be distinguished from the complex differentiated teratomas because of a distinct difference in prognosis.

To evaluate the differences and factors to be considered when measuring intraocular pressure after photorefractive keratectomy[PRK]and laser in situ keratomileusis[LASIK], we prospectively reviewed the medical records of myopic eyes between -4~-7 diopters. Among them, 14 patients, 22 eyes underwent PRK and 10 patients, 18 eyes recieived LASIK. We measured intraocular pressures by Goldmann applanation tonometry preoperatively, 1 month, 3 months and 6 months postoperatively in each group. Corneal curvatures, central corneal thicknesses were measured and compared when measuring intraocular pressure. The postoperative intraocular pressure was lower than the preoperative value in both groups[p<0.01], and the decreased amount of IOP were not statistically different in both groups[p=0.29]. Targeted ablation depth[p=0.19]and ablation diameter[p=0.16]did not show statistically significant correlation to postoperative IOP decrease. In measuring intraocular pressure after PRK or LASIK, attention should be given to the pressure and its interpretation.

The present study investigates the effects of the new Erbium:YAG(yttrium aluminum garnet) laser sclerostomy in eight rabbits eyes. The energy was set at 10mJ per pulse with the frequeny of 10Hz, and the total energy for the full thickness sclerostomy procedure was rated at 90 to 150ml. Following the procedure, the mean intraocualar pressure was significantly reduced for up to 7 days, and the histopathological observation at day 7 revealed clearly demarcated wound margins at the resected sites. The sesults suggest that te Erbium:YAG laser sclerostomy may be a good supportive procedures to conventional treatment of glaucoma.

In air leak syndrome, a significant portion of the volume delivered during a positive pressure breath can be lost through the leak. HFOV can achieve adequate ventilation at lower peak and/or mean intrapulmonary pressure than conventional mechanical ventilation (CMV) and has been an effective treatment of already established air leak syndrome. We report a 1-day-old male infant with severe respiratory failure from pneumothorax and pneumomediastinum, who was refractory to CMV with chest tube drainage. HFOV was applied to this patient for 114 hours, and improvement of oxygenation and ventilation as well as significant reduction of pneumothorax followed.

To evaluate the reproducibility of pulsatile ocular blood flow(POBF), bilateral POBFs of 10 volunteers were measured 3 times serially by OBF tonograph system(OBF laboratories, UK Ltd.). The POBFs were recorded in sitting position using pneumotonometer attached at slit lamp. After measurement of POBF, intraoculat pressure(IOP) was measured by Goldmann applanation tonometry. Mean values of pulse amplitude(PA), pulse volume(PV), POBF, IOP were 2.0+/-0.4mmHg, 5.1+/-1.5microliter, 701+/-197microliter/min, 13.9+/-2.5mmHg, respectively. Average of standard deviation of POBF was 7.0+/-1.9%. Mean value of IOP using Goldmann applanation tonometry was 12.8+/-2.6mmHg. Coefficient of reliability of the repeated measurement of POBF was 83%, analyzed by intraclass correlation. Coefficient of variation of the repeated measurement of POBF was 5.2%. Linear regression analysis of the Goldmann applanation tonometer on the measurements of IOP witn the tonograph showed a regression coefficient of 0.91. In conclusion, reproducibility of POBF measurement by OBF tonograph was acceptable and compatible with conventional technique. Further studies are required to measure the POBF in glaucoma patients.

Development of a malignant tumor within a mature cystic teratoma is a serious event, and occurs in about 1%~4% of cases. The malignant transformation occurs most frequently in the squamous epithelium with the formation of a squamous cell carcinoma. There are 10 cases reported in the literature, in Korea. We report 4 additional cases, which include 3 squamous cell carcinomas and 1 adenosquamous carcinomas, arising in cystic teratoma of the ovary.
