Recently, the proportion of cardiovascular disease as a cause of death in diabetics is in ever increasing tendency. Present study is designed to evaluate the change of myocardial performance by the effect of microangiopathy of diabetics. The measurements of systolic time intervals were obtained from simultaneous high speed recordings(100mm/sec) of electrocardiography, phonocardiography, and carotid pulse tracing in diabetics(male 26, female 31). 1. As the diabetic retinopathy got severe, shortening of LVET and prologation of PEP were noted, but QS2 showed no significant change. 2. PEP/LVET ratio fo diabetics without diabetic retinopathy was significantly higher than that of normal control(p<0.01). 3. PEP/LVET ratio of diabetics with diastolic blood pressure under 95mmHg was significantly higher than that of normal control group(p<0.01), and PEP/LVET ratio of diabetics with diastolic blood pressure over 96mmHg was significantly higher than that of normal control and that of diabetics with diastolic blood pressure under 95mmHg(p<0.01). 4. PEP/LVET ratio of diabetics with proliperative retinopathy was significantly higher than that of normal control and that of diabetics with mild diabetic retinopathy(p<0.01), but this result was not conclusive because of the small case number.

Objectives: . Common cavity deformity is a rare congenital bony labyrinth malformation associated with profound hearing loss. Cochlear implants are widely used for hearing rehabilitation for common cavity deformities; however, the reported prognosis is poor. Due to the deformed anatomical structure, it is important to consider the position of the electrodes to maximize the performance of the cochlear implant. The present study discusses the impact of electrode placement on hearing outcomes. Methods: . A retrospective medical chart review of eight common cavity deformity patients (10 cochlear implants) who received cochlear implants was performed at a single university hospital. In all eight patients, implant surgery was performed using single-slit labyrinthotomy. Electrodes wer e manually bent before insertion to prevent misplacement and to reduce physical damage to the neuroepithelium. Results: . Four of the 10 electrodes were misplaced, with their tips placed in the anterior semicircular canal or internal auditory canal. However, after implant surgery, all patients—including those with misplaced electrodes—gained auditory perception and improved hearing function. One patient who had electrodes that did not contact the inner wall of the cavity showed limited activity of the electrodes (27%) compared to others (64%–100%). Conclusion . Proper contact of the electrode with the inner wall was more likely to be important for cochlear implant success in cases of common cavity deformity than appropriate placement of the electrode tip.

A 6-day-old female infant had generalized superficial pustules which evolved into pigmented maucles, many of which had a peripheral collarvtte of scale. Histopsthologic stadies showed intracormeal aggregates of neutrophils. The appearance of the lesions and histopathologic finding fitted transient neonal pustular melanosis.

Desquamative gingivitis is characterized by a diffuse erythema of the free and attached gingiva associated with areas of vesiculation, erosion, and desquamation. Desquamative gingivitis is not a distinct disease entity but represents a reaction pattern of the gingiva to various stimuli. Pemphigus vulgaris, cicatricial pemphigoid, and lichen planus may presents as desquamative gingivitis. We observed 3 patients whose disease was limited to the gingiva, and studied them by light and direct immunofluorescence microscope. We classified them according to clinical, histologic, and immunopathologic observations. Identification of the underlying causes of desquamative gingivitis is of utmost importance and is dependent upon clinical, histologic, and immunologic criteria.

PURPOSE: We performed dynamic MR imaging using GdDTPA to find characteristic enhancement pattern of hepatic hemangioma distinguishing from hepatocellular carcinoma. METHODS AND MATERIALS: 28 hepatic hemangiomas and 10 hepatocellular carcinomas were evaluated. Serial dynamic scans after Gd-DTPA(0.1mmol/kg) intravenous injection were obtained by using 0.5T machine and analyzed contrast-to-noise ratio(CNR) of the lesion and enhancement pattern on each scan. RESULTS: Hepatic hemangiomas had positive CNR from 1-2 minute images, and revealed typical "fill-in phenomenon" on early phase with prolonged enhancement in 26 cases(92.8%), and early homogeneous enhancement with isointensity on delayed phase in 2 cases(7.2%) of small hemangiome~ Hepatocellular carcinomas revealed inhomogeneous enhancement with hypointensity on delayed phase in 10 cases(100%) and 3 cases (30%) of capsular enhancement. CONCLUSION: Hepatic hemangioma can be easily distinguished from hepatocellular carcinoma by using Gd DTPA enhanced dynamic MR imaging according to its typical enhancement pattern of "fill-in phenomenon" and prolonged enhancement.

BACKGROUND AND OBJECTIVES: One of problems for the management of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) is the difficulty of determining the affected ear using Ewald's second law. The purpose of this study is to develop the new "Bow and Lean Test (BLT)" to determine easily the affected ear of HSC-BPPV and evaluate its efficiency. MATERIALS AND METHOD: We compared the efficiency between the classical method and BLT in 26 patients with HSC-BPPV. The classical method is based on Ewald??s second law comparing the intensity of nystagmus or symptoms in head roll test. BLT is based on the direction of both "bowing nystagmus" and "leaning nystagmus" at head's bowing and leaning state on sitting position. The affected ear is the same direction of bowing nystagmus in canalolithiasis and the same direction of leaning nystagmus in cupulolithiasis. RESULTS: In 26 patents (15 canalolithiasis, 11 cupulolithiasis), 3 (11.5%) patients did not show a prominent affected ear in the classical method, and 7 (26.9%) patients showed the different affected ear between two methods. All 10 patients were successfully treated with just one trial of barbecue rotation based on the affected ear in BLT. Three patients did not show any bowing or leaning nystagmus. The side with canal paresis in all 4 patients, who showed significant canal paresis in bithermal caloric tests, was equal to the affected ear based on BLT. CONCLUSION: "Bow and Lean Test" (also called "Choung's test") is a new method which can easily determine the affected ear of HC-BPPV.
