Posterior capsule opacification(PCO) is a common complication of cataract surgery. The presence of a posterior chamber intraocular lens has been shown to decrease the incidence of the development of PCO. Moreover, there are evidences that the design of intraocular lens may also alter its development. Extracapsular lens extraction with implantation of posterior chamber lens were operated on a consecutive series of 230 eyes. These were evaluated in the viewpoint of PCO development after surgery. All were sulcus fixed and their optic designs were devided into two groups; a group of convex-plano lens with continuous laser ridge including convex-concave lens and a group of biconvex lens. The incidence of PCO was lower in convex-plano lens with continuous laser ridge group(6.7%) than that of boconvex lens group(18.9%). The incidence of Nd:YAG posterior capsulotomy marked 0.0% in continuous ridged group and 1.8% in biconvex group(p<0.05, p Capsule Opacification* ; Cataract ; Incidence ; Lenses, Intraocular* ; Posterior Capsulotomy

The patients of developmental dislocation of the hip(DDH) are almost found after walking age because of early diagnosis of DDH in younger children is not easy. A controversy still exists as to the relative value of closed and operative management in the treatment of a child who has reached walking age. This study is a report of the results of 16 patients(17 cases) in developmental dislocation of the hip who have visited our hospital at the age of 9 months to 3 years old, and have been followed more than 12 months (12-112 months) on review of plain radiographs and arthrograms. The results were as follows 1. The age at diagnosis was 16.4 months(9-31 months) in average. The methods of treatment were conservative for 8 cases, and operation for 4 cases and secondary operation for 5 cases who were failed with conservative therapy. 2. By Severin's radiologic grade, the result was good in 4 cases, fair in 3 cases and poor in 1 case in conservative treatment. In operative treatment, fair was in 2 cases and poor in 2 cases. In secondary operative -patients who were failed with conservative therapy, good was in 2 cases, fair in 2 cases and poor in 1 case. 3. Avascular necrosis of femoral head was developed in 3 cases. 4. In the good reduction as determined by arthrogram according to Race and Herring, we can get a favorable result in conservative treatment, and in the poor reduction as determined by arthrogram, the better

Desmoplastic trichiepithelioma is a solitary tumor of the hair follicle with female preponderance, most commonly located on the face. Clinically the lesions appear annular and firm with a raised border and a depressed nonulcerated center, but the appearance is not so distinctive to hair follicle tumors that definite dignosis is established by the histopathologic findings. We report herein a case a case of desmoplastic trichoepithelioma in a 21-yeaar-old woman who had an asymptomatic hard, annular lesion, 0.4cm sized in diameter with a raised border and a depressed center on the right cheek. Histopathologic findings showed narrow strands of basaloid cells, horny cysts and desmoplastic stnoma, the features corresponding to the desmoplastic trichoepithelioma.

Authors report herein a case of a 27-year-old male patient who had been suffering from chronic ulcerative dermatitis with scar-like changes and successive involvement of the ankles, limb folds, nape and abdomen, and no tendency to heal from age 4. At the age 14, an immunologic study showed a selective IgA deficiency with partial T-lymphocyte inactivation. Ten years later, at age 24, he showed a severe form of morphea over a generalized area and disabling joint contractures, and was diagnosed as disabling pansclerotic morphea with an IgA value that returned to a near normal level. At the age 27, an adult-fist, 7×6×4cm sized, squamous cell carcinoma with an easy bleeding tendency like an overgrowing granulation tissue vascular tumor had developed on the chronic ulcerative lesion on the posterior aspect of the right ankle for 2 months. Aggressive metastatic lesion occurred on the right popliteal area 3 months later. He died 1 month thereafter.

Intestinal metaplasia and dysplasia of the stomach have been stressed as precursors of gastric carcinoma of the intestinal type, although their preneoplastic nature is still debated. In this study, the cytomorphometric and cytokinetic spectra of the suggested preneoplastic and neoplastic lesions of the stomach were investigated. From the resected stomachs of early gastric carcinoma of intestinal type, areas of normal, intestinal metaplasia, dysplasia, and carcinoma were selected. They were immunostained for proliferating cell nuclear antigen, counterstained with propidium iodide, and various nuclear parameters were measured by image analysis. Normal and intestinal metaplastic mucosae differed by the localization of proliferation zone, but not by nuclear profile area, circular shape factor, and proliferation index. In dysplasia, proliferation zone covered large parts of the dysplastic area. Nuclear profile area and proliferation index were larger whereas circular shape factor was smaller than in normal or intestinal metaplasia. Carcinomatous lesion had diffuse proliferation activity, the largest nuclear profile area and proliferating index, and circular shape factor in-between those of normal or intestinal metaplasia and dysplasia. The above results showed a structural spectrum among normal of intestinal metaplasia, dysplasia, and carcinoma of intestinal type in cytomorphometric and cytokinetic terms. The structural spectrum raises the possibility that dysplasia of the stomach is a preneoplastic lesion.

Zonular traction tufts, which exist in 15% of normal population, do not cause retinal detachment by themselves but they can cause traction retinal detaehment when there is traction force added. It is thought that the possibility of development of retinal detaehment increases especially when zonular traetion tufts originate posterior to the vitreous base No case of traction retinal detachment caused by zonular traction tufts has been reported. Here, we report one suspected case of traction retinal detachment induced by zonular traction tufts and lens subluxation.

BACKGROUND:Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation (CPR). The rate of the metronome should be set between 100 to 120 ticks/minute and the speed of ventilation may have crucial effect on the quality of ventilation. We compared three different metronome rates (100, 110, 120 ticks/minute) to investigate its effect on the quality of ventilation during metronome-guided 30:2 CPR. METHODS:This is a prospective, randomized, crossover observational study using a RespiTrainer?r. To simulate 30 chest compressions, one investigator counted from 1 to 30 in cadence with the metronome rate (1 count for every 1 tick), and the participant performed 2 consecutive ventilations immediately following the counting of 30. Thirty physicians performed 5 sets of 2 consecutive (total 10) bag-mask ventilations for each metronome rate. Participants were instructed to squeeze the bag over 2 ticks (1.0 to 1.2 seconds depending on the rate of metronome) and deflate the bag over 2 ticks. The sequence of three different metronome rates was randomized. RESULTS:Mean tidal volume significantly decreased as the metronome rate was increased from 110 ticks/minute to 120 ticks/minute (343±84 mL vs. 294±90 mL, P=0.004). Peak airway pressure significantly increased as metronome rate increased from 100 ticks/minute to 110 ticks/minute (18.7 vs. 21.6 mmHg, P=0.006). CONCLUSION:In metronome-guided 30:2 CPR, a higher metronome rate may adversely affect the quality of bag-mask ventilations. In cases of cardiac arrest where adequate ventilation support is necessary, 100 ticks/minute may be better than 110 or 120 ticks/minute to deliver adequate tidal volume during audio tone guided 30:2 CPR.

PURPOSE: We expected the motion fraction could be checked, with simple radiographic examination, according to the guide-line of fluoroscopic technique, and recovery of the function also could be correlated with the improvement of the motion fraction. MATERIALS AND METHODS: We measured the motion fraction of the glenohumeral and scapulothoracic movement using fluoroscope in 30-degree intervals of arm elevation in the scapular plane. The ratio of glenohumeral to scapulothoracic movement (thetaGH/thetaST) was 1.6 for the full range of motion in scapular plane. During arm elevation, scapular tilting from the coronal plane was decreased from 42 degrees to 20 degrees tilting as well as internal rotation (scapular extension). We also measured the motion fraction (thetaGH/thetaST) and functional recovery of the shoulder in 11 patients after operative treatment of the shoulder instability in 15 patients from December 1996 to August 1997. RESULTS: We could find out a significant correlation between the recovery of motion fraction and shoulder function. These results would be applied in planing rehabilitation program after treatment of the shoulder instability. CONCLUSIONS: The measuring technique of glenohumeral to scapulothoracic movement (thetaGH/thetaST) with fluoroscopy could be applied to the simple radiographic measurement at the out-patient clinic in order to identify the pathology and recovery of shoulder motion after treatment

PURPOSE: Pink gingival esthetic especially on the anterior teeth has been an important success criterion in implant-supported restoration. Inter-implant papillae are a critical factor for implant esthetics, and various techniques for inter-implant papilla reconstruction have been introduced. The aim of this study is to suggest and evaluate a surgical technique for reconstructing inter-implant papillae. METHODS: A 28-year-old man had an implant placed on the #13 and #14 area. Four months after implant placement, a second stage surgery was planned for inter-implant papilla reconstruction. At the time of the abutment connection, I-type incisions were performed on the #13i & #14i area followed by full-thickness flap elevation and connection of a healing abutment on underlying fixtures without suture. RESULTS: Two weeks after the second stage implant surgery, soft tissue augmentation between the two implants was achieved. CONCLUSIONS: I-shaped incisions for papilla reconstruction performed during the second stage implant surgery were useful for inter-implant papilla reconstruction and showed a good esthetic result.

Dermoid cysts are rare congenital tumors that occur primarily at the midline at a characteristic intradural location. However, dermoid cysts located at extradural and lateral regions have been rarely reported until now. In the present study, the authors demonstrate the unusual instance of an intracranial extradural dermoid cyst at the lateral sphenoid ridge. A 53-year-old woman admitted because of progressive headache and dizziness. The patient had no neurologic deficits, and magnetic resonance imaging with no contrast enhancement revealed a mass at the right sphenoid ridge. The mass was accompanied with sphenoid bone erosion visible on computed tomography. The patient underwent right pterional craniotomy, and the tumor including the capsule was totally resected. Presence of a dermoid cyst was confirmed with histopathological examination. The patient had no complications during the postoperative period. This study suggests that dermoid cyst should be considered for differential diagnosis of extradural and lateral intracranial masses.
