Enchondroma is a benign tumor mainly developed in the hand and uncommon in the foot. Even if it is in the foot, most are in the phalanges and distal metatarsals of the foot. Enchondroma in the calcaneus is very rare. A 44-year-old male suffered from left heel pain for several months, authors treated it with curettage and bone graft, it was histologically confirmed as an enchondroma in the calcaneus. The authors presented a rare case presentation of an enchondroma in the calcaneus with pain.

PURPOSE: The effect of superior clear corneal incision and transverse astigmatic keratotomy on the with-the-rule astigmatism in sutureless, small incision cataract surgery was evaluated. METHODS: The postoperative keratometric changes were evaluated in 18 eyes with more than 1.4 diopter (D) of preoperative with-the-rule astigmatism, having sutureless, superior clear corneal incision phacoemulsification. Five eyes over 2.8 D with-the-rule astigmatism also had transverse corneal relaxing incision. Keratometric readings were done within 1 month preoperatively, 1 day and 2 months postoperatively and the changes were statistically analyzed. Simple subtraction method and Cravy method were used for the analysis of astigmatic changes. RESULTS: The mean astigmatism showed decreasing trend, 2.08, 2.25, 1.12 D, within preoperative 1 month, at postoperative 1 day and 2 months respectively and 3.70, 2.48, 2.06 D respectively when transverse keratotomy was added. The reduction of astigmatism was statistically significant at postoperative 2 months (P<0.05; Wilcoxon rank-sum test) and it was more significant with transverse astigmatic keratotomy (P<0.05, Mann-Whitney U test). CONCLUSIONS: The with-the-rule astigmatism over 1.40 D could be reduced in cataract surgery by sutureless, superior clear corneal incision and transverse corneal relaxing keratotomy.

BACKGROUND: To investigate the possibie difference, if any, between office blood pressure(BP) and home BP may be important in the diagnosis and treatment of hypersensive patients. This report deails the difference between the two BP's and the usefulness of digital electronic sphygmomanometer(DES) for self-monitoring of home BP. METHODS: The BP's of 14 patients with essential hypertension were measured with mercury sphygmomanometers at outpatient department by physician and with DES at home(twice a day) by the patients. Patients were followed up every 2 weeks for 4 weeks and previous 2 weeks' average home BP's were compared with the office BP's of each 2 weeks' end. RESULTS: There was a significant difference between office and home BP(both systolic and diastolic) ; office average BP(151/95mmHg) was higher than home average BP(136/86mmHg). CONCLUSION: Caution may be needed in the interpretation of office BP unless it is measured several times after adequate rest.

PURPOSE: To assess the usefulness and reliability of the IOL power calculation computer program ('POWER!'). METHODS: Calculation times and projected postoperative refractive values of 100 patients with 'POWER!' program were compared with those of the program mounted on the Humphrey R A/B scan system (model 820) by SRK-II and SRK/T formula. RESULTS: There was no significant difference between the projected postoperative refractive values of 'POWER!' program and Humphrey R A/B scan system (paired-t test, p>0.05). Calculation time of 'POWER!' was shorter than that of the program mounted on the Humphrey R A/B scan system incalculating more than 3 sets of IOL (paired-t test, P<0.05) and there was no internal calculation error (ztest, p>0.05). CONCLUSIONS: 'POWER!' is a useful and reliable program for IOL power calculation using SRK-II and SRK/T formula.

Extracapsular cataract extraction(ECCE) with posterior chamber intraocular lens(PC-IOL) implantation is now favorable surgery to improye decreased visual acuity due to cataract. But this surgical method often causes secondary glaucoma, hyphema, uveitis, and macular edema, which result in poor visual outcome. We studied the causes of elevated intraocular pressure(IOP) retrospectively in 15 eyes of 14 patients among 1,657 cases undergone with the implantation of PC-IOL, in recent 5 years. As the preoperative causes, preexisting uveitis(5 eyes, 33%) and underlying glaucoma(3 eyes, 20%) were important factors. Postoperative causes were newly developed uveitis(1 eye, 6.7%), steroid responder(2 eyes, 13.3%) and idiopathy(4 eyes, 27%). From the above results, We should take more meticulous care in intraoperative and postopertive management in cases of preexisting uveitis and glaucoma.

The ileal atresia has been commonly accepted to be caused by a vascular accident during early intrauterine period. Thanks to the development of anesthesia, surgical techniques, postoperative supportive treatment and the hyperalimentation technique, the motality rate of this disease has been decreased. In spite of these developments, premature and very low birth weight babies should be given more attention because they still have a high motality rate. The authors report a successful treatment of ileal atresia in a 1,200g premature female infant. The proximal distended and hypertrophied intestine was resected. The distal small bowel was transected using a oblique line to create a fish-mouth. An end to end anastomosis was performed. We gave postoperative care, such as incubator care, fluid therapy, gastric decomprssion and total parenteral nutrition(TPN). TPN was initiated on postoperative one day. Calories were increased from 60cal/kg to 90cal/kg. TPN was stopped on the postoperative 24 day when the patient tolerated full strength milk feeding. Eighteen months postoperatively, she is healthy and her weight is 9.0kg(9 percentile).

PMMA(polymethyl Methacrylate) introcular lens(IOL) has been designed for making surface hydrophobic. Hydrophilic IOL has advantages such as less damage of corneal endothelium and less attachment of inflammatory cells on the IOL surface especially in case of uveitis or diabetes mellitus. Therefore, hydrophilic IOL is regarded as a biocompatible IOL. In this study, we made PMMAs hydrophilic using hydrolysis (described in The Effect of Hydrophilic Treatment of PMMA using Hydrolysis on Light Transmission and Cell Attachment in Vitro (I)). The number of PMMA treated in each condition was twelve and each PMMA has been implanted into rat peritoneal space. These PMMAs were examined with inverted light microscope and scanning electron microscope 3 days and 7-14 days after implantation. The number of cell attachment on pMMA-1 or PMMA-2 was about 1/5 of that on PMMA-0 and the difference was statistically significant (p<0.05). There was no statistically significant difference of cell attachment between PMMA-1 and PMMA-2. The cells on PMMA-0 showed prominent cytoplasmic processes, while those on PMMA-1 or PMMA-2 showed little processes. The majority of the surface PMMA-0 was covered with membrane light sheet. Therefore, it was found that treatment of PMMA with Isopropranol and NaOH was useful in making PMMA dydrophilic and decreasing the cell attachment on PMMA in vivo.
