Subcutaneous angiolymphoid hyperplasia is an uncommon disease characterized by eosinophilia, proliferation of the capillary vessels and lymphoid tissue and infiltration of the inflammatory cell, especially eosinophils. The etiology of the disease are obscure, but probably trauma, lower grade infection, nervous factor & hormonal status etc. The predilection sites are face, ears, scalf & neck, but rarely reported in the extremities. We experienced a case of subcutaneous angiolymphoid hyperplasia of the inguinal region and anteromedial side of the proximal thigh in a 10 year-old man who complained pain and tenderness on the above region. The patient was treated by excision with satisfactory result.

BACKGROUND: Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. MATERIAL AND METHOD: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. RESULT: After surgical correction peak aortic gradient fell from 58.4+/-17.6, to 23.7+/-17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6+/-24.3 to 143.7+/-27.1 mmHg and from 1.78+/-0.4 to 1.76+/-0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10+/-0.2, to 1.27+/-0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2+/-24.9 to 57.1+/-27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. CONCLUSION: We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.

In the therapeutic or the nutritional aspects, Zn2+ has been used as a supplement in a variety of drugs. Most of divalent or trivalent cations affect ion channels in the cell membranes of various organs. In particular, Zn2+ has been regarded as a potassium (K+) channel blocker in the field of electrophysiology. ATP-sensitive K+ (KATP) channel, which is a kind of inward rectifier K+ channel, resides in the cell membrane of pancreatic beta cells and plays an important role in glucose-induced insulin secretion. The glucose increases intracellular ATP concentration, and this inhibits KATP channels. The inhibition of KATP channels activity depolarizes the cell, and subsequently, insulin is released by Ca2+ influx through the voltage- gated Ca2+ channels. Here, we demonstrate that KATP channels in the pancreatic beta cells are also the targets of extracellular Zn2+ blockade and its blockade is dependent on intracellular ATP concentration. This may be a compensatory mechanism preventing the oversecretion of insulin from the Pancreatic beta cells triggered by Zn2+ intake in a physiologically fasting condition.

Subdural hematoma is a common disease of intracranial hemorrhage that accounts for 11-21% of all head trauma patients. It is defined as a hematoma that develops between dura mater and subarachnoid space. In elder patients, mild trauma may not always be accurately recognized and symptoms may not develop slowly due to the large area of subdural space. Headache is the most common symptom of subdural hematoma and may be associated with hemiplegia, dysarthria, sensation disorder, conscious disorder, and etc. We present, with a literature review, a case of a patient who developed subacute subdural hematoma after performing Brandt-Daroff habituation exercise to treat benign paroxysmal positional vertigo.
