RESUMEN

PURPOSE: To identify the clinical features and outcomes of endogenous endophthalmitis in Korea. MATERIALS AND METHODS: We reviewed 18 patients with endogenous endophthalmitis at 2 Korean hospitals, treated over a 14 year period between January 1993 and December 2006. RESULTS: The comorbidities observed in these cases were diabetes mellitus and liver cirrhosis. The most common pathogens, which were found in 7 patients each (38.9%), were Klebsiella pneumonia and Pseudomonas aeruginosa. All patients were treated with systemic antibiotics and fortified topical antibiotics. A surgical approach including vitrectomy was performed in 9 cases (50.0%). The prognosis was generally poor, and visual acuity improved slightly in 6 patients (33.3%). CONCLUSION: In this study, diabetes mellitus and Klebsiella pneumonia showed a close relationship with endogenous endophthalmitis, respectively. Endogenous endophthalmitis is a serious risk to sight and careful attention to establishing the diagnosis and management may decrease the ocular morbidity.

RESUMEN

The effect of drugs on calcium-binding to cardiac muscle membrane fragments and its turnover rate was studied. Ouabian, acetylcholine, isoproterenol and norepinephrine did not have any effect either on calcium-binding to membrane fragments or an washout ahnd release curves of previously bound calcium. Local anesthetics inhibited the calcium-binding. Tetracaine at concentrations of 1 and 10 mM inhibited the calcium-binding by 30% and 54%, respectively, while 10 mM lidocaine inhibited it by 17%. Propranolol, a well-known adrenergic beta-blocker, also inhibited calcium-binding at the external calcium concentration of 10(-3) M. This effect of propranolol may be attributed to its local anesthetic-like action, rather than to the adrenergic blocking effect.
