RESUMO

OBJECTIVES: To evaluate the analgesic and anti-haemorrhagic efficacy of platelet-rich plasma (PRP) among patients undergoing tonsillectomy. DESIGN: A systematic review and meta-analysis of randomised controlled trials (RCTs). SETTING: PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL) and Google Scholar databases were screened from inception until July 2021, and updated in December 2021. PARTICIPANTS: Patients undergoing tonsillectomy. MAIN OUTCOME MEASURES: The efficacy endpoints of postoperative pain and haemorrhage were summarised as standardised mean difference (SMD) and risk ratio (RR), respectively, with 95% confidence interval (CI). RESULTS: Seven RCTs Seven RCTs were analysed, comprising a total of 392 patients. Risk of bias evaluation showed an overall high risk in one RCT, low risk in four RCTs and some concerns in two RCTs. The pooled results revealed that the mean postoperative pain score was significantly reduced in favour of the PRP group compared with the control group (SMD = -1.38, 95% CI [-1.91, -0.85], p < 0.001). Subgroup analysis showed the effect estimate was statistically significant for early postoperative pain (Day 0 to Day 3), without substantial difference between both groups on late postoperative pain (Days 5 and 7). Moreover, the rate of postoperative haemorrhage was significantly reduced in favour of the PRP group compared with the control group (RR = 0.16, 95% CI [0.05, 0.50], p = 0.001). Subgroup analysis showed the effect estimate was statistically significant for the rate of primary and secondary haemorrhage. CONCLUSION: PRP was associated with significant reduction in postoperative pain and haemorrhage among patients undergoing tonsillectomy.

RESUMO

Background: Phakic intraocular lenses (pIOLs) have proven to be excellent substitutes for excimer laser keratorefractive surgery in certain situations. We aimed to assess the efficacy and safety of two pIOLs, the implantable collamer lens (ICL V4c) versus the implantable phakic contact lens (IPCL V2), for myopic correction. Methods: In this prospective randomized clinical trial, we allocated eligible eyes with myopia > - 6 diopters into IPCL or ICL implantation groups, each including 100 eyes of 100 individuals. Preoperative and postoperative assessments at 3, 6, and 12 months included measurements of the spherical equivalent (SE), uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), intraocular pressure (IOP), maximum keratometry (K1), minimum keratometry (K2), mean keratometry (Kmean), anterior chamber depth (ACD), anterior chamber angle (ACA), and endothelial cell density (ECD). Results: The groups had comparable demographic characteristics and baseline visual and anatomical values (all P > 0.05). The UCDVA, BCDVA, and SE of the two groups were comparable at baseline and at all postoperative follow-up examinations (all P > 0.05). Both groups experienced significant improvements in UCDVA, BCDVA, and SE at three months postoperatively (all P = 0.001), and measurements remained stable for up to 12 months. Keratometry readings were comparable between the groups over the follow-up period and remained unchanged at all visits (all P > 0.05). The ACA in the ICL group was significantly decreased at three months postoperatively (P = 0.001) and then widened significantly at 6 and 12 months (both P = 0.001). In the IPCL group, the postoperative ACA was significantly decreased at three months (P = 0.001) and was comparable to that in the ICL group (P > 0.01). However, at the 6- and 12-month postoperative visits, the ACA was significantly narrower in the IPCL group than in the ICL group (both P = 0.001). The ACD in both groups was decreased at three months postoperatively (both P = 0.001) and remained stable until the end of the study. The ECD remained comparable between the groups at all postoperative visits (all P > 0.05). We did not observe a significant ECD reduction in either group at any postoperative follow-up visit (all P > 0.05). We encountered no serious complications in either group. Conclusions: ICL and IPCL had comparable safety and efficacy outcomes in terms of anterior chamber morphometrics, visual and refractive results, and corneal parameters. Further multicenter randomized clinical trials with longer follow-up periods, larger sample sizes, and measurement of additional anterior chamber and corneal morphometrics, vault, and other vision parameters are needed to verify these findings.

RESUMO

Background: Associations between retinal venous occlusion (RVO), elevated intraocular pressure, and glaucoma have been reported. Further investigations into structural alterations in the fellow eyes of individuals with unilateral RVO have revealed that the peripapillary retinal nerve fiber layer is thinner than in healthy eyes, suggesting that there may be systemic risk factors common to both RVO and glaucoma. We aimed to evaluate changes in peripapillary retinal nerve fiber layer thickness (pRNFLT) among individuals with unilateral branch retinal vein occlusion (BRVO). Methods: This prospective observational study recruited 30 individuals (60 eyes) with newly diagnosed unilateral BRVO and macular edema, and a control group of 30 healthy individuals (30 eyes) with no abnormalities on fundus examination or concurrent systemic comorbidities. After baseline measurements, the participants were reassessed at 6, 12, and 24 months by measuring global and sectoral pRNFLT using spectral-domain optical coherence tomography. Results: The mean age and sex distributions were comparable between the patient and control groups (both P > 0.05). When compared to fellow eyes, global and sectoral pRNFLT in eyes with BRVO were significantly higher at baseline (all P < 0.05). Over time, pRNFLT decreased dramatically, and by the conclusion of the two-year follow-up, there was a significant reduction from baseline in the affected eyes (all P < 0.05). Likewise, affected eyes experienced a significant improvement in best-corrected distance visual acuity and central macular thickness over the two-year follow-up (both P ≤ 0.001). Comparing the global and all-sector pRNFLT of fellow eyes in the patient group with those of normal eyes in the control group, there were no significant differences at any visit, except in the temporal sector, which revealed a significant reduction in pRNFLT at 24 months in the fellow eyes of patients with unilateral BRVO (P = 0.02). Conclusions: Patients with unilateral BRVO experienced a significant reduction in pRNFLT in the affected eyes and, to a lesser extent, in the fellow eyes, compared with that of the control arm, suggesting that they are prone to retinal nerve fiber layer damage. The reduction in pRNFLT in the normal fellow eyes of patients with BRVO may be attributed to age or concurrent systemic comorbidities. Further studies with long follow-up periods are required to shed light on the etiology of functional and structural changes in both the retinal nerve fiber layer and ganglion cell complex in the normal and affected eyes of patients with unilateral BRVO.

RESUMO

Reports of thrombotic response after receiving COVID-19 Adenoviral-Vector Based Vaccines raise concerns about vaccine-induced thrombotic thrombocytopenia (VITT); therefore, we conduct this systematic review to report susceptible demographics outcomes, commonalities, and prognosis of reporting cases. We identified published articles by searching PubMed, SCOPUS, and Web of Science from December 2020 till May 2021, with an updated search in September 2021. All case reports and case series reporting thrombotic response after receiving COVID-19 Adenoviral-Vector Based Vaccines were eligible for including. In addition, two authors independently extracted data and assessed the quality of the included studies. A total of 157 patients with thrombotic events after the ChAdOx1 nCoV-19 vaccine and 16 patients with thrombotic events after Ad26.COV2. S vaccine was included in our study. 72% of the ChAdOx1 nCoV-19 cases were females, while in Ad26.COV2.S subgroup, all reported patients were females. The commonest presentations were deep vein thrombosis 20 (12.7%) and cerebral venous sinus thrombosis 18 (11.5%) in the ChAdOx1 nCoV-19 subgroup while cerebral venous sinus thrombosis 14 (87.5%) and pulmonary embolism 2 (12.5%) in the Ad26.COV2. S subgroup. In this study, we described the certain demographics associated with VITT and the clinical presentations of those cases in the ChAdOx1 nCoV-19 and Ad26.COV2. S vaccines. Young individuals, particularly females, may be more susceptible to VITT, and future studies should seek to confirm this association. In addition, the clinical presentation of VITT commonly includes cerebral thrombi, pulmonary embolism, and deep venous thrombosis, but other presentations are also possible, highlighting the importance of clinical vigilance in recent vaccine recipients.

RESUMO

We aimed to assess the efficacy of Hibiscus sabdariffa in patients with mild-to-moderate hypertension or metabolic syndrome (MetS) by comparing it against placebo, antihypertensive drugs, or other herbal products. Four databases were searched for randomized clinical trials (RCTs) examining the efficacy of H. sabdariffa in patients with mild-to-moderate hypertension or hypertension associated with MetS. Data on the change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) were extracted and analyzed using Review Manager Version 5.3. A total of 13 RCTs (1205 participants) were analyzed. Hibiscus sabdariffa significantly reduced both SBP and DBP compared with placebo (mean difference -6.67, P = 0.004 and -4.35 mm Hg, P = 0.02). Subgroup analysis showed that change in SBP and DBP was statistically significant in patients with only hypertension, whereas not significant in patients with hypertension associated with MetS. When H. sabdariffa was compared with active controls (antihypertensive drugs or other herbals), the change in SBP and DBP was not statistically significant (all P > 0.05). Hibiscus sabdariffa is effective in reducing the SBP and DBP in patients with mild-to-moderate hypertension, but was neither effective in those with MetS nor superior to antihypertensive drugs. Further RCTs are required to determine the long-term efficacy of H. sabdariffa and to describe patients who would benefit most from this treatment.

RESUMO

OBJECTIVES: This pilot survey aims to study the oral manifestations associated with COVID-19 infection and report the prevalence of oral signs and symptoms in COVID-19 patients. MATERIALS AND METHODS: From May 15 to June 10, 2020, we used an online questionnaire containing the oral manifestations that are expected to be associated with the COVID-19 infection. Adults in our survey who have been diagnosed with COVID-19 positive were confirmed with reverse transcriptase PCR (RT-PCR), and isolated in various hospitals in Cairo, Egypt. RESULTS: This pilot study included 58 (53.4% males and 46.6% females) COVID-19 patients ages 18-46 years, and 13 (22.4%) were healthcare workers. Our results showed that 67.2% of the patients had at least one manifestation related to the oral cavity and salivary glands, and 32.8% (n = 19) did not have any symptoms associated with the oral cavity. The highest prevalence symptoms were dry mouth 39.7% (n = 23), gustatory dysfunction as 34.5% (n = 20) loss of salt sensation, 29.3% (n = 17) loss of sweet sensation, and 25.9% (n = 15) altered food taste, while the least prevalent symptoms were tongue redness 8.8% (n = 5), and gingival bleeding 7% (n = 4). The most frequently associated symptoms were loss of salt and sweetness, as reported by 27.6% of the participants. However, there was no significant association between the incidence of oral symptoms and demographic data (age, gender, or job) of the patients (p > 0.05). CONCLUSIONS: Based on limited data, COVID-19 significantly impacts the oral cavity and salivary glands, as salivary gland-related symptoms and taste disorders are highly prevalent in COVID-19 patients.

RESUMO

PURPOSE: To discuss the ocular manifestations provoked by novel coronavirus 2019 (COVID-19) disease in humans, the natural history of the disease in the eye, and its treatment. METHODS: We designed a narrative review of the ocular manifestations of COVID-19 based on the literature published till July 30, 2020. The databases were PubMed, Scopus, Cochrane Library, Google Scholar, and ScienceDirect. The inclusion criteria were (1) all types of clinical studies and (2) the topic was COVID-19 and its association to the eye regarding the current guidelines. RESULTS: From 168 abstracts screened, 61 papers fully filled the inclusion criteria after the full-text screening. The 61 records include 13 case reports, 17 prospective (case series or cross-sectional) studies, 8 retrospective studies, 12 literature reviews (one systematic review), and 11 letters to the editor. The majority of the papers agreed that ophthalmic manifestations due to COVID-19 were few and rarely encountered. The main ocular pathology seemed to be conjunctivitis, where the viral polymerase chain reaction also happened to be most detectable. Posterior segment or neuro-ophthalmic manifestations were scarce. Viral genome detection in the eye as well as viral portal of entry to the globe is still vague. CONCLUSION: The exact incidence of ocular manifestations in COVID-19 disease is uncertain. Conjunctivitis is the most prevalent ocular manifestation. It is still a debate whether the eye is a portal of entry for infection.
