Single stage Large LR recession with or without MR resection and its motor outcomes in Concomitant Exotropia

Exotropia is a manifest outward deviation of the visual axes, which is either constantly or intermittently present. Untreated, poorly controlled intermittent exotropia later progresses to constant exotropia. Sensory exotropia is unilateral divergent misalignment of the eyes, resulting from loss of vision or long-standing poor vision in an ey

Epidemiology of dengue in Sri Lanka before and after the emergence of epidemic dengue hemorrhagic fever.

Before 1989, dengue epidemiology in Sri Lanka was characterized by frequent transmission of all four dengue serotypes but a low incidence of dengue hemorrhagic fever (DHF). After 1989, cases of DHF dramatically increased. Here we present the results of epidemiologic studies conducted in Colombo, Sri Lanka before and after epidemic emergence of DHF in 1989. We compared the proportion of dengue cases among people with fever attending clinics from 1980 to 1984 and in 1997 and 1998 to determine if an increase in dengue transmission was associated with more DHF cases being reported. We also compared the relative distribution of dengue virus serotypes circulating in Colombo before and after the emergence of DHF. We detected no significant differences in dengue as a proportion of fever cases or in serotype distribution between the pre and post-DHF periods. We conclude that an increase in virus transmission or a change in circulating serotypes does not explain the epidemic emergence of DHF in Sri Lanka

Peribulbar anesthesia: efficacy of a single injection with a limited local anesthetic Volume

Introduction: Cataract surgery can be performed with peribulbar anesthesia. The classical technique consists of two injections of local anesthetics. The purpose of our Study was to assess peribulbar anesthesia with a single injection and a limited volume of local anesthetics. Material and method: After local ethics committee agreement and oral consent, patients scheduled for cataract surgery using peribulbar anesthesia were prospectively included. The lower temporal puncture was performed with a peribulbar needle with lignocaine sedation. The mixture of local anesthetics was administered with tactile control of orbital pressure. The punch was followed by a 10 min compression of the ocular globe. Akinesia, analgesia, complications, and surgical conditions were noted. Results: A total of 100 patients were included in the Study. Lignocaine was given at a rate of 1.2 mg/kg. The total amount of local anesthetics used was 4.0 ± 0.9 ml. At 15 minutes, ninety patients had akinesia, and 7% had mild chemosis. There were no complications from the puncture. At 5 minutes, 92 percent of patients had akinesia, and at 15 minutes, 94 percent of patients had it. In 94 percent of patients, fixed the eye, and in 94 percent of patients, the vision was central. In 86 percent of cases, the levator muscle motor of the eyelid was blocked. In 7% of patients, moderate chemosis was found. Many of the patients had positive surgical outcomes. Conclusion: Peribulbar anesthesia performed with a single injection and a limited volume of local anesthetics allows cataract surgery in good conditions for the surgeon with excellent analgesia for the patient
