A girl aged 18 years and 1 month, had a Angle's Class Iff malocclusion, characterized by anterior crossbite, anterior crowding, and constriction from right lower 2nd p emolar to right lower 2nd molar This ~i5 5s patient underwent scaling and 84148 extraction, and multibanded system was placed. After 14 months, anterior crossbite and crowding was corrected, andbothdental arches were improved. After 6 months from debanding, band space disappeared, and any relapse was not detected.

After dual plating with a locking compression plate for comminuted intraarticular fractures of the distal humerus, the incidence of ulnar nerve injury after surgery has been reported to be up to 38%. This can be reduced by an anterior transposition of the ulnar nerve but some surgeons believe that extensive handling of the nerve with transposition can increase the risk of an ulnar nerve dysfunction. This paper reports ulnar nerve injuries caused by the incomplete insertion of a screw head in dual plating without an anterior ulnar nerve transposition for AO/OTA type C2 distal humerus fractures. When an anatomical locking plate is applied to a distal humeral fracture, locking screws around the ulnar nerve should be inserted fully without protrusion of the screw because an incompletely inserted screw can cause irritation or injury to the ulnar nerve because the screw head in the locking system usually has a slightly sharp edge because screw head has threads. If the change in insertion angle and resulting protruded head of the screw are unavoidable for firm fixation of fracture, the anterior transposition of the ulnar nerve is recommended over a soft tissue shield.

Essential hypertension is an important public health problem in Korea-being common, asymptomatic, easily treatable, and often leading to lethal complication in left untreated. The number of patients with hypertension has been significantly increased, and this factor may be an importnat one responsible for the increase in cardivascular mortality during past 20 years in Korea. As the drug therapy for hypertension needs longer period, it is very important to evaluate the efficacy and the adverse effects. Thirty patients(17 men and 13 womon) with essential hypertension were evaluated in this study. All patients had received oral Isradipine 1.25~2.5mg b.i.d. for 8 weeks. 1) The systolic and diastolic pressure were decreased significantly(166.8+/-9.0mmHg vs 147.3+/-12.0mmHg, p<0.001 and 100.3+/-4.0mmHg vs 90.3+/-6.1mmHg, p<0.001, respectively) 2) Heart rate, body weight, laboratory tests, chest X-ray, ECG studies were not changed significantly. 3) The systolic pressure was lowered by 20mmHg or more in 17 cases(56.7% of total), and the diastolic pressure was lowered by 10mmHg or more in 20 cases(66.7% of total) at 8 weeks after Isradipine administration. 4) The adverse effects of Isradipine were edema in 3(10%), constipation in 2(6.7%), headache in 2(6.7%), and insomnia, dizziness and dry mouth in 1 patient respectively, and none of them discontinued Isradipine administration due to adverse effects. In many patients with essential hypertension there is an effective response to Isradipine, even though there may be some mild adverse effects.

A number of noninvasive technics have been advocated as reflecting left ventricular performance. These methods include systolic time intervals, echocardiography and imaging of the left ventricular chamber with radionuclides during systole and diastole. Radionuclide evaluation of left ventricular function by means of the gamma camera and gating currently appears to be the most reliable noninvasive method for approximating angiographic evaluation of left ventricular performance. Utilizing the radionuclide angiography, we measured the left ventricular function in 19 normal healthy control, 60 patients with coronary artery diseases 7 patients with dilated cardiomyopathy, 5 patients with hypertension. 1) Left ventricular ejection fraction decreased in 12 patients with anterior myocardial infarction (39.9+/-11.6%), 17 patients with inferior myocardial infarction (49.9+/-8.4%) and 7 patients with dilated cardiomyopathy (19.0+/-5.8%), and there was a statistically significant difference compared with 19 normal control group (63.5+/-8.2%)(p<0.005). However there were no statistically significant difference between normal control group, patients with hypertension (58.8+/-7.6%) and patients with angina pectoris (60.1+/-6.5%). 2) Left ventricular ejection fraction decreased in both anterior and inferior myocardial infarction, and there was a statisically significant difference between both groups (p<0.01). All 13 patients with acute myocardial infarction had abnormal LVEF (40.5+/-9.1%) whcih was significantly lower than that of 16 patients with old myolardial infarction (50.1+/-10.5%)(p<0.01).

Leiomyosarcoma of the prostate is a rare malignant tumor. It originates from the smooth muscles of the prostatic gland and is usually found during old ages. Prognosis is usually poor especially in childhood. We report a case of leiomyosarcoma of the prostate measured 320gm in 64 years old man.

Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

Central pontine myelinolysis (CPM) is a demyelinating disorder that almost exclusively affects the central portion of basis pontis and occurs in patients with malnutrition, chronic debilitating disorders and electrolyte abnormalities. CPM after liver transplantation is considered that had the relationship to rapid correction of hyponatremia and shift in osmolality. Our first case of 4 liver transplantations altered consciousness at the 5th day after transplantation and did not recover fully until 14 months. At first, atrial fibrillation and atelectasis due to left main broncheal obstruction were thought the causes of impaired consciousness as postoperative hypoxic event. At that time, CT scan showed diffuse brain atropy that suggested previous hepatic encephalopathy and/or hypoxic ischemic encephalopathy. After that, MRI revealed CPM and diffuse cortical atropy. We concluded that CPM associated with rapid correction of hyponatremia perioperatively alter patient's consciousness with hypoxic brain injury.
