Endpgenous bacterial endophthalmitis develops mainly in a extremely ill patient or a immunologically compromised patient. As reported earlier, early suspicion and careful diagnostic evaluation and early aggressive treatment are important to treat endophthalmitis and prevent poor visual acuity. The authors experienced a case of endogenous endophthalmitis developed from pneumonia in chronic alcoholics patient. The pathogen was proved to be a Staphylococcus aureus by the culture of specimen obtained from the aqueous. Systemic, topical, subconjunctival and intravitreal antibiotic therapy were done, but the patient's eye progressed to phthisis state.

BACKGROUND: P300 component of the long latency auditory evoked potentials (LLAEPs) provides information on conscious and cortical funtion. The P300 wave occures only for stimuli that somehow capture the patients attention. Therefore LLAEPs implys a degree of cognitive processing. We studied sedation scale and P300 wave to determine if LLAEPs could be utilized as electrophysiologic predictors of sedation. METHODS: The P300 component of LLAEPs from vertex was recorded from 10 ASA physical status I and II patients undergoing elective surgery while they listened via headphones to a series of clicks which were interrupted unpredictably by a tone burst (2 KHz) before and after diazepam 0.04 mg/kg and 0.08 mg/kg IV. The patients were asked to concentrate on the clicks and to press a button whenever they detected a 2 KHz tone. And sedation scale also was measured. RESULTS: Amplitude of P300 was decreased and latency of P300 was increased in a dose-dependent manner with IV diazepam. Amplitude was greatest and latency was shortest in awake. And sedation scale also was increased according to increased IV diazepam adminstration. CONCLUSIONS: Both amplitude and latency may be highly related to the sedation scale with progressively increasing dose of diazepam. Therefore we conclude that P300 component of LLAEPs can be utilized as an electrophysiologic predictor of awareness and sedation.

The hemodynamic feature of the tetralogy of Fallot (TOF) is best characterized by equality of left and right ventricular peak systolic pressure. The interventricular septum is flattened and thickened. Even after the right ventricular pressure is normalized in the postoperative period, the morphological abnormality continues for some time We have analyzed the morphological changes of the IVS echocardiographically after total correction and tried to correlate them with the prognosis of the patients. Forty five patients underwent total correction of TOF between May 1991 and July 1992.The IVS morphology was assessed with 2-D echocardiography before and after surgery. The control group consisted of 15 normal subjects(8 with functional cardiac murmur and 7 with non-cardiac diseases).We also evaluated the influence of the residual pulmonary regurgitation(PR) or pulmonic stenosis (PS) upon sequential changes in the end-systolic configuration and the thickness of the IVS. The following results were obtained. 1) Four months after total correction the IVS thickness and configuration at end-systole of the study patients were normalized, and they were not significantly different compared to those of the control group. 2) The postoperative residual PR of mild to moderate degree did not influence the course of morphological normalization. On the other hand, the postoperative residual PS greater than moderate degree hindered the normalization process. And the morphological abnormalities in the patients with the residual PS lasted longer than in the patients with the residual PR. 3) It would be necessary to perform cardiac catheterization in order to evaluate and to take care of the residual hemodynamic abnormalities if the IVS morphology remains to be abnormal even after one year after total correction.

The constricted ear was suggested by Tanzer for the purpose of obviating the confusion involving lop ear, cup ear and prominent ear as defect whose helix turns down, and scapha and fossa triangularis are narrowed. The constricted ear has a spectrum of severity and therefore, requires a graded surgical approach. Tanzer has described the degree of deformities of the constricted ear as falling into three groups. For the correction of constricted ear, there are numerous techniques but we have had difficulties in adopting these techniques in various type. We also describe the various constricted ear as the Tanzer's classification and adopted three methods to each type, banner flap(group I), concha cartilage graft (group II) and rib cartilage graft(group III) for reducing postoperative deformity and confusion in correcting the ear deformities. Constricted ear repairs must be individualized to accomodate each specific deformity. We corrected 22 cases of constricted ear in 20 patients using each optimal method described above according to the degree of deformities. Mild deformities need only reshaping and adjusting of existing tissues, moderate deformities need additional skin and severe deformities require a cartilage graft. For correction of constricted ear, accurate identification of the severity of deformity is essential. The results were satisfactory and we report our experience with relative literatures.

BACKGROUND AND OBJECTIVES: The aim of this study was to analyze the summating potential (SP)/action potential (AP) ratio of electrocochleography (ECoG) recorded from the position of SP peak. We compared the SP/AP ratios of negative polarity and positive polarity graphs from the same ECoG of each patient by assuming different the position of SP peak. In addition, we attempted to evaluate the utility of two different manners of recording the ECoG graph in the diagnosis of Meniere's disease. SUBJECTS AND METHOD: Retrospectively, we analyzed the results of ECoG in 67 patients with unilateral definite Meniere's disease. ECoG was analyzed in two different manners. From the AP peak, the SP peak was determined close when positioned in the negative polarity; on the other hand, SP peak was considered distant when positioned in the positive polarity. The SP/AP ratio was interpreted with reference to the base line value. The ratio of two different ECoG values from each patient of Meniere's disease was calculated. RESULTS: In the abnormal side, the negative polarity ECoG showed significantly greater value of SP/AP ratio (mean: 0.334±0.10) than the positive polarity ECoG (mean: 0.283±0.09) (p<0.001). In the normal side, the negative polarity ECoG, showed significantly greater value of SP/AP ratio (mean: 0.250±0.09) than the positive polarity ECoG (mean: 0.204±0.06), as well as in the abnormal cases (p<0.001). CONCLUSION: The standard SP/AP ratio for the diagnosis of Meniere's disease can be variable according to the manner of determining the SP peak.
