RESUMO
OBJECTIVE: To evaluate anatomical and functional outcomes after silicone oil extraction in patients with retinal detachment and proliferative vitreoretinopathy in an eye care referral center in Joinville, SC, southern Brazil. METHODS: Retrospective, noncomparative study of patients with retinal detachment and posterior proliferative vitreoretinopathy followed up after silicone oil removal. Prophylactic 360-degree peripheral laser photocoagulation was performed one to three months before silicone oil extraction. Patients with cataract underwent a combined clear corneal phacoemulsification with intraocular lens implantation in the same procedure. Anatomical outcomes were related to the duration of silicone oil tamponade and the surgical procedure performed. Functional outcomes were divided into three categories (stability, worsening, or improvement) according to visual acuity variation before the surgery and at the last follow-up visit. RESULTS: Fifty-three patients were followed up for a mean period of 1,262 days. Fourteen eyes (26.4%) underwent cataract surgery combined with silicone oil extraction. Forty-eight eyes (90.5%) had attached retina at the last follow-up examination. Time of intraocular tamponade and association of phacoemulsification with silicone oil extraction were not considered as risk factors for retinal redetachment. Twenty-three cases (43.4%) showed visual acuity improvement, whereas 11 cases (20.8%) were stable and 19 cases (35.8%) showed visual acuity worsening. Five patients with attached retina had unexplained optic disc atrophy. CONCLUSION: Most patients had good anatomical and visual outcomes after silicone oil extraction. Prophylactic 360-degree laser retinopexy may have led to favorable outcomes. Benefits of silicone oil extraction and the associated risks of complications due to a new surgical procedure must be carefully evaluated before surgical indication.
RESUMO
OBJECTIVE: This study outlined the epidemiological profiles of patients who were admitted to the Pediatric Intensive Care Center at Albert Einstein Israelite Hospital during 2009. METHODS: Data were retrospectively collected for all patients admitted to the PICC during 2009. A total of 433 medical charts were reviewed, and these data were extracted using the DATAMARTS System and analyzed using the statistical software package STATA, version 11.0. RESULTS: There were no statistically significant differences in regards to patient gender, and the predominant age group consisted of patients between the ages of 1 to 4 years. The average occupancy rate was 69.3% per year, and there was a greater number of admissions during April, August, and October. The average length of stay at the hospital ranged from 9.7 to 19.1 days. Respiratory diseases were the main cause for admission to the Pediatric Intensive Care Center, and the mortality rate of the patients admitted was 1.85%. CONCLUSIONS: Respiratory diseases were the most common ailment among patients admitted to the Pediatric Intensive Care Center, and the highest mortality rates were associated with neoplastic diseases.
