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.

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: 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.

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.

In order to see whether the binocular patching with cycloplegia improves the prognosis in the treatmet of traumatic hyphema, we studied prospectively 77 patients with nonperforating traumatic hyphema who were admitted and treated at the Chonnam University Hospital between January 1994 and July 1995. We analyzed the clearance time of blood clot in the anterior chamber, the incidence of rebleeding and the final visual acuity. The patients were divided into four groups : group I, of 17 patients treated by monocular patching ; group II, of 19 patients treated by monocular patching with cycloplegia ; group III, of 20 patients treated by absolute bed rest with binocular patching ; group IV, of 21 patients treated by absolute bed rest with binocular patching and cycloplegia. The average clearance time of blood clot was 7.4 days in group I, 7.4 days in group II, 6.9 days in group III and 7.5 days in group IV. The incidence of rebleeding was 5.8% (n=1) in group I, 10.5% (n=2) in group II, 0% (n=0) in group III, 14.3% (n=3) in group IV. The final visual acuity of 0.6 or better was achieved in 10 patients (58.8%) of group I, 13 patients (68.4%) of group II, 13 patients (65.0%) of group III, 14 patients (66.7%) of group IV. In the treatment of traumatic hyphema, binocular and monocular groups as well as cycloplegic and non-cycloplegic groups showed no significant difference from each other in the clearance time of blood clot, incidence of rebleeding and the final visual acuity.

PURPOSE: To study the refractive outcome of cataract surgery employing partial coherence interferometry (PCI) and to compare this outcome with that of A-scan ultrasound in a prospective study of 96 eyes of 96 patients that underwent phacoemulsification with intraocular lens (IOL) implantation. METHODS: The SRK-T formula was employed, using PCI (IOL Master(R): the only commercially available model) and A-scan ultrasound data, to predict patients' implanted IOL power. Four to six weeks after cataract surgery, the refractive outcome was determined, and results from the two different biometry methods were compared. RESULTS: Ninety-six patients (mean age: 67.64, SD: 9.91) underwent phacoemulsification with IOL implantation. The optical axial length obtained using the IOL Master(R) was significantly longer (p<0.001, Student's t-test) than the axial length obtained via by A-scan ultrasound, 24.29 (SD 1.80) mm vs. 24.19 (1.75) mm. When using the IOL Master(R), the mean prediction error (PE; planned target of refraction - postoperative refraction) was 0.30 (0.60) D, and the mean absolute prediction error (APE) was 0.51 (0.44) D. When using A-scan ultrasound, the mean PE was 0.01 (0.64) D, and the mean APE was 0.47 (0.43) D. The difference in mean APE between the two biometry methods was not statistically significant (p=0.236, Wilcoxon signed rank test). Among the eyes with an axial length greater than 25 mm, as determined by A-scan ultrasound, the difference in the mean APE was not statistically significant (0.48 (0.87) vs. 0.58 (0.61), p=0.094). Likewise, among the eyes for which with axial length measured by A-scan ultrasound longer than IOL Master(R), the difference in the mean APE error was not statistically significant, (0.33 (0.30) vs. 0.46 (0.41), p=0.110). CONCLUSIONS: IOL power calculation using the PCI is as accurate as that using A-scan ultrasound for predicting the postoperative refractive state of patients who have undergone cataract surgery.

Ten cases infected with Taenia saginata were treated with Bithionol, 2, 2' thiobis (4,6-dichlorophenol) which is well known as an excellent anthelminthhic against paragonimiasis and their follow-up studies were carried on within 3 to 12 months after treatment. Bithionol, 50 mg dose per kg of body weight was divided into two equal dose and administered orally in 30 minutes intervals. Three hours later, this was followed with a sodium sulfate or magnesium sulfate purge. The strobilas without scolices were found in the stools after the medication and the follow-up studies have shown the complete deworming in all cases. It is well tolerated, toxic effects being uncommon and when present, limited to mild gastro-intestinal disturbances.

PURPOSE: We performed this study to identify the patterns of lateral neck node involvement and to define the appropriate method of neck node dissection in papillary thyroid carcinoma. MATERIAL AND METHODS: One hundred seventy one patients who had undergone radical neck dissection for lateral cervical lymph node metastasis of papillary thyroid cancer from January 1986 to December 1995 were analyzed retrospectively. Total operations were 178 cases and total radical neck dissections were 206 cases (bilateral in 28 cases, unilateral in 150 cases). Of these 206 cases, group I (170 cases, 82.5%) who had undergone comprehensive radical neck dissection or modified radical neck dissection and group II (36 cases, 17.5%) who had undergone jugular neck dissection were studied. RESULTS: In group I, the most prevalent site of lymph node metastases was level III, followed by level II, IV, V and I. The 158 cases of group I in which nodes in the posterior triangle of the neck were not palpable preoperatively, were divided into five groups, 0, 1, 2, 3 and 4 or more, according to the number of clinically positive internal jugular nodes. The incidence of microscopically positive nodes in level V was significantly lower in the groups of one or less palpable internal jugular nodes (p=0.0007). In the 60 of 158 cases with the evaluable CT scans of the neck, the incidence of microscopically positive nodes in level V was significantly lower in the groups of two or less positive nodes on CT scan (p=0.0001). And, there were no significant differences in the incidence of recurrence, sites of recurrence, distant metastases, mortality between Group I and Group II. CONCLUSION: The modified radical neck dissection might be justified in most papillary thyroid cancer patients with clinically positive lateral neck nodes. However, in patients with only one or less palpable node and two or less positive nodes on CT scan along the jugular lymphatic chains but negative in level V, it appears to be beneficial to perform a jugular neck dissection in reducing cosmetic disfigurement and preserving function.
