Posterior chamber intraocular lenses were implanted into 20 eyes without the posterior capsular capsular support by securing both haptics of the lens to the sclera with 10-0 prolene suture. The follow-up period ranged from 6 to 24 months(average 9.4 months). At the last follow-up visit, 17 eyes(85%) had a vision of 0.7 or better. The position of the implanted lens was proved satisfactory when compard with eyes with posterior chamber intraocular lens without scleral fixation suture by postoperative A-scan measurement of the anterior chamber depth, the results of refraction and slit-lamp examination. There were no eyes with remarkable decentration or tilt of the implanted lens. In two eyes, intraoperative bleeding occurred from the inferior chamber angle and ceased spontaneously. Postoperatively there were no remarkable inflammatory responses or complications. From the results, we suggest that the position of scleral puncture with a hypodermic needle is 1.2 - 1.4mm from the posterior surgical limbus in the upper quadrant and the advancement of the needle is directing parallel to the posterior surface of the iris.

Our previous experimental work with tissue plasminogen activator (TPA) suggested the possibility of the clearance of vitreous hemorrhage by repetitive injections of low-dose TPA. We therefore investigated in rabbits the effect of both repeated injections of TPA and the change of the integrity of the vitreous body on the clearance of vitreous hemorrhage. Vitreous hemorrhage was produced by intravitreal injection of 0.05 ml of autologous whole blood in the pigmented rabbit eyes with intact vitreous or gas-compressed vitreous. Three intravitreal injections of 3-g TPA (total dose of 9 microgram), separated by 7-day intervals, were performed. The endpoint for vitreous hemorrhage clearance was defined as clear visualization of the posterior central retina of the rabbits. Regardless of whether gas compression vitrectomy was performed, repeated injections of low-dose TPA resulted in rapid clearance of fresh vitreous hemorrhage in approximately two to three weeks after the last TPA injection. No evidence of retinal toxicity was seen in all experimental groups. Repetitive injections of low-dose TPA may be effective in the treatment of fresh vitreous hemorrhage.

PURPOSE: To evaluate the results of five-pin external fixation, with the fifth pin stabilizing the distal radius articular fragment, for unstable distal radial fractures. MATERIALS AND METHODS: Twenty cases of unstable distal radial fractures were treated with five-pin external fixation (5-pin group). The fifth pin was inserted into the distal articular fragment and attached to the external fixation frame. Metacarpal pins were removed at sixth week in 12 cases and at third in 8 cases, and radial pins were removed at eighth or ninth week. The radiographic results of 5-pin group were compared with those of 20 cases of traditional four-pin external fixation (4-pin group). RESULTS: The postoperative radial inclination was 23.1 degrees in 5-pin group and 22.2 degrees in 4-pin group; while at last follow-up 21.8o and 15.1 degrees respectively. Postoperative volar tilt was 8.5 degrees and 7.3o; while at last follow-up 6.3 degrees and 0.1 degrees respectively. Postoperative radial shortening was 0.3 mm, 0.4 mm; while at last follow-up 1.1 mm and 2.1 mm respectively. In 5-pin group, there were no significant differences in results whether the metacarpal pins were removed at sixth or third week. CONCLUSION: Five-pin external fixation, with the fifth pin stabilizing the distal articular fragment, enhanced early motion of the wrist maintaining fracture stability in unstable fractures of the distal radius.

PURPOSE: Enteroviral infection is a common viral illness in children. We undertook this study in attempt to comprehend the epidemiologic and clinical features of enteroviral infections, particularly EV71 in children. METHODS: We enrolled 63 children with enteroviral infection at Severance Children's Hospital in Seoul between May and August 2009. Reverse transcriptase-polymerase chain reaction (RT-PCR) was performed from stool or cerebrospinal fluid samples, which were then tested for enteroviral infection. Viral isolation and serotype identification also were performed by RT-PCR. RESULTS: A total of 63 patients with clinical diagnosis of enteroviral infections were enrolled; of those, 38 (60%) were positive for enterovirus. The mean age of the patients was 2 years and 7 months and the sex ratio of male to female was 0.9:1. Their clincal manifestations included aseptic meningitis (21 cases, 55%), HFMD (16 cases, 42%), herpangina (5 cases, 13%), neonatal fever (2 cases, 5%), encephalitis (1 case, 3%), and myocarditis (1 case, 3%). Serotypes of isolated enteroviruses were EV71 (8 cases, 21%), coxsackievirus B1 (8 cases, 21%), coxsackievirus A16 (2 cases, 6%), coxsakievirus A2 (1 case, 3%), coxsakievirus A5 (1 case, 3%), and echovirus 9 (1 case, 3%). Clinical symptoms of EV71 infection included HFMD (5 cases, 63%), aseptic meningitis (3 cases, 38%), encephalitis (1 case, 13%), and myocarditis (1 case, 13%). A positive rate of C-reactive protein in EV71 was higher than those in other enterviral infections. However, there was no statistically significant difference in other laboratory findings. CONCLUSION: We reported on identified enteroviruses, including EV71, during a period of 3 months in the summer of 2009. In this study, EV71 infection frequently occurred in male and clinical manifestation caused by EV71 was a more severe disease than that due to other enterviral infections. There is a need for continuous surveillance of enteroviral infection and its clinical manifestations for diagnosis and treatment of enteroviral infection.

BACKGROUND: Basal cell carcinoma(BCC) is the most common primary cutaneous neoplasm in Korea. Since the majority of BCCs occur on the head and neck and the goal of the BCC treatment is the complete removal of tumor, Mohs micrographic surgery is ideally suited for maximizing cure rate with minimizing tissue loss. OBJECTIVE: The purpose of this study is to evaluate the depth of excision as well as the lateral margins of BCC and to correlate these with the clinicopathologic aspects of the tumors. METHODS: Twenty patients with 21 BCCs (10 primary, 11 recurrent) diagnosed in the Department of Dermatology of Dong-A University Hospital from March, 1992 through December, 1993 were studied prospectively. RESULTS: 1. Sixty percent of tumors in primary BCCs in our series had a 2-mm maximal margin and 81.8% of recurrent BCC were eradicated with 4-mm or more lateral margin. 2. All the recurrent basal cell carcinomas (8 cases) measuring greater than 15-mm required more than 4-mm margin for the total removal. 3. More than 90% of BCC on the nose in our series required the removal of periosteum/perichondrium or the excision of whole layer. CONCLUSION: Mohs micrographic surgery is an appropriate tool to use in proposing guidelines for the treatment of skin cancer because the most accurate method of determining the actual extent of skin cancer can be achieved.
