This study aims to evaluate the efficacy of Apnex, Inspire, and ImThera hypoglossal nerve stimulation (HGNS) devices in changing the severity of obstructive sleep apnea (OSA). ology: A systematic search was conducted across the databases to collect baseline and postoperative outcome measures. Articles were then filtered and data from post-filtration was extracted. The efficacy of each device was assessed individually, and the reported outcomes were analyzed at short-term (≤ 1 year) and long-term (> 1 year) intervals. A total of 30 papers were included; 26 were single-arm studies encompassing 549 middle-aged overweight patients. Four RCTs included 273 participants. Results show that HGNS is an effective and safe treatment option. The Inspire device significantly improved, reducing the apnea-hypopnea index (AHI) by -20.14 events/h in the short term and -15.91 events/h in the long term. It also decreased the oxygen desaturation index (ODI) by -14.16 events/h (short term) and -12.95 events/h (long term). Patient-reported outcomes showed decreased Epworth Sleepiness Scale (ESS) scores by -5.02 (short term) and -4.90 (long term) and improved Functional Outcomes of Sleep Questionnaire (FOSQ) scores by 3.58 (short term) and 3.28 (long term). The Apnex and the ImThera devices featured similar improvements but to a lesser extent. Hypoglossal nerve stimulation is a safe and effective treatment for patients with OSA, exhibiting high adherence and satisfaction rates. However, it is important to note the potential for refining selection criteria to include a wider spectrum of patients with OSA.

To compare the final cycloplegic refraction of tropicamide 1% and cyclopentolate 1% in children 3-16 years of age with brown irides. Randomized, controlled, multicenter prospective clinical trial. Included patients were randomized to either cyclopentolate 1% or tropicamide 1% in the first visit with autorefraction measurements. Each subject underwent a second cycloplegic refraction using the other agent on a separate visit with a minimum of 1-week interval and a maximum of 12 weeks. We measured the change in SE (ΔSE) for each eye by deducting the SE before cycloplegia from the SE after cycloplegia. A total of 185 eyes from 94 children aged 3-16 years (average= 8.79 ±3.11 years) were included. The average SE of both eyes before cycloplegia was -0.082 ± 4.8 diopters. The SE after instillation of cyclopentolate and tropicamide in both eyes was 1.07±5.2 and 0.96±5.1, respectively (P value < .001). The average ΔSE after cycloplegia was 1.15±1.2 for cyclopentolate and 1.04±1.2 for tropicamide (P value < .001). The difference between ΔSE of cyclopentolate and tropicamide was found statistically significant at 0.11±1.2 (P < .001), although clinically insignificant. The ΔSE between the 2 drops before and after cycloplegia in both eyes for all refractive error groups was clinically insignificant. The greatest effect of cyclopentolate and tropicamide was in hyperopic eyes with ΔSE of 1.54±1.4 and 1.39±1.4, respectively. Tropicamide might be an effective and safe replacement for cyclopentolate in the refracting nonstrabismic pediatric population 3-16 years of age regardless of their refractive error status.

Background: To describe Purtscher’s and Purtscher-like retinopathy clinical features, etiologies, management options, and visual outcomes. Methods: Our protocol was registered on PROSPERO [registration number: CRD42023406843]. Seven online databases were searched: PubMed, Scopus, Medline, ScienceDirect, CENTRAL, clinicaltrials.gov, and Google Scholar. Original articles were included if they reported at least one subject diagnosed with Purtscher’s or Purtscher-like retinopathy. The primary outcome is to describe the clinical features of Purtscher and Purtscher-like retinopathies, including etiologies, results of related investigations, management lines, and visual outcomes. All analyses were conducted with the use of Statistical Package for Social Sciences (SPSS) version 27 (IBM SPSS Corp, SPSS Statistics ver. 26, USA) and Cochrane’s RevMan software. The methodological quality of included studies was assessed using the NIH quality assessment tools. Results: A total of 114 articles were included, describing 168 cases of Purtscher’s and Purtscher-like retinopathy. Patients were evenly distributed between males (50.89%) and females (49.11%). Average age of patients was 34.62 years old. Trauma was the leading cause of retinopathy, being reported in 39.88% of our patients, followed by systemic lupus erythematosus (SLE) (13.1%) and acute pancreatitis (11.9%). Bilateral symptoms were reported in 57.7% of patients with centrally blurred vision being the most complained symptom (OS: 34.32% and OD: 18%). 75% of patients elicited bilateral retinal findings. Cotton-wool spots were of highest prevalence (58%). Purtscher flecken was seen in 53% of patients. Macular edema was seen in 13% of patients. Overall, patients had a favorable prognosis (53%). Conclusion: Purtscher’s and Purtscher-like retinopathies are rare sight-threatening retinopathies that develop most commonly following trauma or other systemic diseases as SLE and acute pancreatitis. Little data is available regarding these conditions, and available data is of low quality. Patients develop bilateral disease in approximately 50% of cases, and several retinal findings are observed, with no specific tendency. Most observed signs are cotton-wool spots in around 55% of patients and Purtscher flecken in 51% of patients. Patients spontaneously recovered, although data is not conclusive. No clear prognostic value of etiological factors is identified, and further research is required in this regard.

Systematic reviews are used in medical research to synthesize evidence by collecting evidence from available literature without overlooking important sources or pieces. Several guidelines are available for the methodological implementation of a systematic review; however, none of them include case reports or case series as a potential source of information that could be pooled and analyzed. Although case reports may be criticized as an evidence source, they are important for documenting certain types of evidence such as rare conditions, adverse events, or novel emergent diseases. In this article, we attempt to set the foundation for a guideline on the systematic review of cases, and we suggest a step-by-step guide for investigators to employ for systematically reviewing case reports. We also dissect the application of this methodology in the available literature and review a case study of a systematic review of case reports. Generally, case reports can be synthesized into a systematic review, providing evidence on matters that may be hard to investigate using other methodologies, but concerns regarding quality and level of evidence remain present.

This study evaluates the efficacy and safety of the combined microneedling (CMNT) with minoxidil versus minoxidil monotherapy for the treatment of androgenetic alopecia (AGA), with a focus on the impact of microneedling parameters on treatment outcomes. We conducted a systematic review and meta-analysis (PROSPERO: CRD42024594487) of randomized controlled trials (RCTs) comparing CMNT versus minoxidil alone for AGA, following PRISMA guidelines. A comprehensive search across six databases was performed up to September 8, 2024. We identified 12 RCTs involving 631 AGA patients, with a total of 11 RCTs included in the meta-analyses. CMNT significantly improved hair count compared to minoxidil monotherapy (SMD 1.32, 95% CI 0.73–1.92, p < 0.01), with substantial heterogeneity (I² = 88%, p < 0.01). Subgroup analyses indicated no significant effect of microneedling (MN) depth (≤ 1 mm vs. >1 mm), duration (≤ 12 weeks vs. >12 weeks), or technique(device) (electrodynamic vs. rolling) on hair count outcomes. Additionally, A meta-analysis of six RCTs demonstrated a significant improvement in hair diameter with CMNT (SMD 0.34, 95% CI 0.11–0.58; p < 0.01), with no observed heterogeneity (I² = 0%). Investigators and patient’s self-assessment scores were also improved. Adverse events were more frequent with CMNT (74 vs. 59 events), however they were generally considered mild or self-limiting. CMNT significantly enhances hair count and diameter in AGA patients with mild adverse events. MN parameters including depth, duration, and technique variations did not significantly affect hair count outcome, suggesting microneedling as a promising adjunctive AGA treatment.

Introduction: Dry eye disease (DED) is a common and multifactorial disease of the ocular surface which causes visual disturbance and feelings of discomfort among patients. The prevalence rate among medical students is an important issue to consider. This study investigates the relationship between caffeine consumption, sleeping habits, use of electronic devices, and DED among a convenient sample of medical students in Jordan. Methods: This cross-sectional online survey enrolled medical students from all six medical schools in Jordan. The questionnaire, which was shared via social media platforms, assessed socio-demographics, caffeine consumption amounts and patterns, sleep quality, and the use of electronic devices and their relation to ocular discomfort, DED, and related symptoms. The ocular surface disease index (OSDI) questionnaire was also administered to quantify the symptoms of DED. Results: A total of 1223 students participated in this study (RR=24.46%); 64% were females, and 43% were in their clinical placement years. Of the participants, 317 (25.92%) had normal eyes, and 906 (74.08%) had symptomatic DED. Of the students, 1206 (98.6%) used electronic devices directly before bed, and only 399 (32.62%) used blue-light-protective glasses. Lower DED risk was linked to male gender (OR=0.535, 95% CI 0.392– 0.73, p < 0.01), clinical years of medical school (OR=0.564, 95% CI 0.424– 0.75, p< 0.01). Poor sleep quality corresponded to more incidence of DED, regardless of sleeping for 5– 6 hours (OR=3.046, 95% CI 1.299– 7.139, p=0.01) or for less than 5 hours (OR=3.942, 95% CI 1.824– 8.519, p< 0.01). Also, caffeine consumption only marginally affected its incidence, but the results were statistically insignificant. Conclusion: Female gender, basic science years, and spending more than 6 hours looking at screens were significantly associated with symptomatic DED. Caffeine consumption did not pose any significant risk to the incidence of DED.
