RESUMO

Objective: The objective of this study is to evaluate post-acute symptoms in patients with confirmed severe and critical coronavirus disease 2019 infections. Methods: We evaluated patients with confirmed severe and critical coronavirus disease 2019 infections. Post-acute symptoms were defined as symptoms persisting 4 weeks after the onset of the symptoms and classified as pulmonary, muscular, hematologic, neuropsychiatric, renal, and dermatological. Results: We recovered data from 565 patients (43.7% female) with a mean age of 61.1 years. In 18.2%, at least one hospital readmission was necessary and 11.1% died. In 62.6%, there was at least one persistent symptom, and 28.8% had more than one. Among associated factors, obesity, intensive care support, and mechanical ventilation were related to persistent symptoms. Conclusion: The most prevalent symptoms were pulmonary and neuropsychiatric sequelae, as reported in previous studies. This finding underscores the severity of the coronavirus disease 2019 infection and the need for follow-up after recovery from the initial illness. Obese patients, those requiring mechanical ventilation, female patients, and increased hospital length are at greater chance of having persistent symptoms.

RESUMO

PURPOSE: To compare the efficacy of different concentrations of topical lidocaine gel with standard subconjunctival anesthesia. METHODS: This was a prospective randomized controlled pilot study with 3 different groups. Group SC received subconjunctival lidocaine and proparacaine drops as needed during surgery. Group L2 received 2% lidocaine gel and group L5 received 5% lidocaine gel. Both lidocaine gel groups could receive another gel dose as needed during the procedure. The primary outcome was pain, which was experienced during and after surgery. The assessment was done using a 10-point linear analog scale at predetermined stages of surgery (1-first incision, 2-pterygium body excision, 3-conjunctival suturing, 4-immediate postoperative period after patching, and 5-assessment by a trained nurse in the absence of a surgeon after operation). RESULTS: We enrolled 45 consecutive patients who underwent primary pterygium surgery. Statistical significance between groups was found in mean pain at administration (2.2 vs. 0.4 vs. 0.0 in SC, L2, and L5 groups, respectively, with P < 0.05). The number of reapplications of anesthetic drops did not differ between the groups. We found a correlation between reapplication of the anesthetic and pain at administration and duration of the procedure. CONCLUSIONS: We demonstrated that the use of lidocaine gel at concentrations of 2% and 5% in pterygium surgery was as effective as subconjunctival injection of lidocaine in reducing intraoperative and postoperative pain, producing significantly less pain during initial administration of the anesthetic.

RESUMO

PURPOSE: To investigate retinal changes prior to vascular signs in patients with type 2 diabetes without diabetic retinopathy or with mild non proliferative diabetic retinopathy. METHODS: A cross-sectional study was performed in three groups: patients without diabetes, patients with type 2 diabetes without diabetic retinopathy, and patients with diabetes with mild diabetic retinopathy. Analysis of retinal layers was performed objectively with the Cirrus Review Software 6.0 (Carl Zeiss Meditec, Dublin, CA, USA). Macular cube scans were analyzed with regard to: the ganglion cell layer + inner plexiform layer analysis, retinal nerve fiber layer thickness, central subfoveal retinal thickness and average macular thickness. RESULTS: In total, 102 patients were included in this study, of which 28 (27.4%) were classified into control group, 46 (45.0%) classified as diabetic patients with no diabetic retinopathy and 28 (27.4%) classified as mild diabetic retinopathy. Quantitative analysis with the Cirrus software showed that the mean ganglion cell layer and mean retinal nerve fiber layer were thinner in diabetes without diabetic retinopathy group when compared to controls. ANOVA with Bonferroni post test indicated a statistically significant reduction in average retinal thickness in mild diabetic retinopathy group (P = 0.032) compared to control and reduction in ganglion cell layer in diabetes with no diabetic retinopathy (P = 0.039) and mild diabetic retinopathy (P = 0.003). Also indicated reduction in retinal nerve fiber layer in diabetic without diabetic retinopathy and eyes with mild diabetic retinopathy (P < 0.001), compared to controls. CONCLUSIONS: Our study found reduction in thickness of ganglion cell layer and retinal nerve fiber layer in patients with diabetes without diabetic retinopathy, which suggests neuroretinal changes before vascular signs of diabetic retinopathy.
