Meta-Analysis Review
BACKGROUND
Intranasal agents may be ideal for the treatment of migraine patients. Many new acute intranasal-specific therapies have been developed, but few of them have been directly compared. The aim of this network meta-analysis (NMA) was to compare the efficacy and safety of various intranasal agents for the treatment of acute migraine in adult patients.
METHODS
The Cochrane Register of Controlled Trials, Embase, and PubMed were searched from inception to 15 August 2023. Randomized controlled trials (RCTs) using intranasal agents (no restrictions on dose, formulation, dosing regimen or timing of the first dose) to treat adult patients with acute migraine were included. The primary efficacy endpoint was pain freedom at 2 h, and the primary safety endpoint was adverse events (AEs). The analysis process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
RESULTS
Nineteen studies (21 RCTs, 9738 participants) were included. Compared to the placebo, 5 mg of zolmitriptan using a conventional liquid nasal spray device was the most effective for pain freedom at 2 h [odds ratio (OR): 4.67, 95% confidence interval (CI): 3.43 to 6.43] and 24 h (OR: 5.49, 95% CI: 3.58 to 8.42) among all the interventions. Butorphanol nasal spray 1 mg was the most effective (OR: 8.62, 95% CI: 1.11 to 66.92) for pain freedom at 1 h, but with low-quality evidence. DFN-02 presented the highest freedom from nausea (OR: 4.95, 95% CI: 1.29 to 19.01) and phonophobia (OR: 5.36, 95% CI: 1.67 to 17.22) at 2 h, albeit with lower odds of achieving complete pain freedom. ROX-828 showed the highest improvement in freedom from photophobia at 2 h (OR: 4.03, 95% CI: 1.66 to 9.81). Dihydroergotamine nasal spray was significantly associated with the highest risk of AEs (OR: 9.65, 95% CI: 4.39 to 21.22) and was not recommended for routine use. Zavegepant nasal spray demonstrated the lowest risk of AEs (OR: 2.04, 95% CI: 1.37 to 3.03). The results of sensitivity analyses for the primary endpoints (pain freedom at 2 h and AEs) were generally consistent with those of the base case model.
CONCLUSIONS
Compared with other new intranasal-specific therapies in treating migraine attacks, zolmitriptan nasal spray 5 mg was the most effective agent for pain freedom at 2 h. Zavegepant nasal spray 10 mg had the fewest adverse side effects.

Review
Vernal keratoconjunctivitis (VKC) is a chronic, bilateral corneal and conjunctival problem which typically presents in young individuals. VKC is characterized by itching, photophobia, white mucous discharge, lacrimation, foreign body sensation, and pain due to corneal involvement of shield ulcers. Vernal keratoconjunctivitis is categorized within ocular diseases. The diagnosis is clinical, as no sure biomarkers pathognomonic of the disease have yet been identified. The VKC therapy relies on different types of drugs, from antihistamines and topical steroids to cyclosporine or tacrolimus eye drops. In extremely rare cases, there is also the need for surgical treatment for the debridement of ulcers, as well as for advanced glaucoma and cataracts, caused by excessive prolonged use of steroid eye drops. We performed a systematic review of the literature, according to PRISMA guideline recommendations. We searched the PubMed database from January 2016 to June 2023. Search terms were Vernal, Vernal keratoconjunctivitis, and VKC. We initially identified 211 articles. After the screening process, 168 studies were eligible according to our criteria and were included in the review. In this study, we performed a systematic literature review to provide a comprehensive overview of currently available diagnostic methods, management of VKC, and its treatments.

Despite many years of clinical use of isotretinoin, a comprehensive review of evidence for isotretinoin therapy in patients with acne is lacking. We searched MEDLINE, Embase, Cochrane Central, relevant web pages and bibliographies for randomized controlled trials in acne evaluating isotretinoin vs. control (placebo or other therapy). Data were extracted and summarized descriptively. Eleven trials were identified (total 760 patients randomized), containing mostly men. Mean treatment ages ranged from 18 to 47·9 years and participants generally had moderate-to-severe acne. Across all trials, isotretinoin therapy reduced acne lesion counts by a clinically relevant amount, and always by a greater amount than control, which was either placebo (two studies), oral antibiotics (seven studies) or other control (two studies). Across trials with an overall low risk of bias, two of three demonstrated statistically significant differences between isotretinoin and control. The frequency of adverse events was twice as high with isotretinoin (751 events) than with control (388 events). More than half of all adverse events were dermatological and related to dryness. Adverse events from isotretinoin causing participant withdrawal from trials (12 patients) included Stevens-Johnson syndrome, cheilitis, xerosis, acne flare, photophobia, elevated liver enzymes, decreased appetite, headaches and depressed mood. This review suggests that isotretinoin is effective in reducing acne lesion counts, but adverse events are common. This study was registered with PROSPERO number CRD42015025080.

Meta-Analysis
SIGNIFICANCE
This study reports the prevalence and relative risk of photophobia in patients with traumatic brain injury (TBI).
OBJECTIVES
This study aimed to conduct a systematic review and meta-analysis to determine the prevalence and relative risk of photophobia in patients with TBI.
DATA SOURCES
Three databases were used for literature search: PubMed, EMBASE, and Cochrane Library.
STUDY APPRAISAL AND SYNTHESIS METHODS
Publications reporting the prevalence of photophobia after TBI in patients of any age were included. A series of meta-regression analyses based on a generalized linear mixed model was performed to identify potential sources of heterogeneity in the prevalence estimates.
RESULTS
Seventy-five eligible publications were identified. The prevalence of photophobia was 30.46% (95% confidence interval [CI], 20.05 to 40.88%) at 1 week after the injury. Prevalence decreased to 19.34% (95% CI, 10.40 to 28.27%) between 1 week and 1 month after TBI and to 13.51% (95% CI, 5.77 to 21.24%) between 1 and 3 months after the injury. The rapid decrease in the prevalence of photophobia in the first 3 months after a TBI injury was significant (P < .001). Three months post-TBI, the prevalence of photophobia leveled off to a near plateau with nonsignificant variability, increasing between 3 and 6 months (17.68%; 95% CI, 9.05 to 26.32%) and decreasing between 6 and 12 months since TBI (14.85%; 95% CI, 6.80 to 22.90%). Subgroup analysis of 14 publications that contained control data showed that the estimated risk ratio for photophobia was significantly higher in the TBI than in the control group during the entire 12 months after TBI.
CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS
This study demonstrates that photophobia is a frequent complaint after TBI, which largely resolves for many individuals within 3 months after the injury. For some patients, however, photophobia can last up to 12 months and possibly longer. Developing an objective quantitative methodology for measuring photophobia, validating a dedicated photophobia questionnaire, and having a specific photophobia International Classification of Diseases, Tenth Revision code would greatly improve data gathering and analysis.

Child photophobia. Photophobia is abnormal intolerance of light. It is a commonest complaint and a reason for ophthalmological assessment in adults. Child photophobia is less frequent and must be explored. First of all, life-threatening pathology (meningitis) should be ruled off. Then, thorough ocular examination will establish a right diagnosis. Ocular surface alterations are prominent cause of photophobia. Retinal and optic pathway diseases could also lead to light aversion. This article is a systematic review of conditions linked with photophobia in children. It also offers a panorama of clinical imaging in typical cases.

OBJECTIVE
Blepharospasm is a type of dystonia where the diagnosis is often delayed because its varied clinical manifestations are not well recognized. The purpose of this study was to provide a comprehensive picture of its clinical features including presenting features, motor features, and non-motor features.
METHODS
This was a two-part study. The first part involved a systematic literature review that summarized clinical features for 10,324 cases taken from 41 prior reports. The second part involved a summary of clinical features for 884 cases enrolled in a large multicenter cohort collected by the Dystonia Coalition investigators, along with an analysis of the factors that contribute to the spread of dystonia beyond the periocular region.
RESULTS
For cases in the literature and the Dystonia Coalition, blepharospasm emerged in the 50s and was more frequent in women. Many presented with non-specific motor symptoms such as increased blinking (51.9%) or non-motor sensory features such as eye soreness or pain (38.7%), photophobia (35.5%), or dry eyes (10.7%). Non-motor psychiatric features were also common including anxiety disorders (34-40%) and depression (21-24%). Among cases presenting with blepharospasm in the Dystonia Coalition cohort, 61% experienced spread of dystonia to other regions, most commonly the oromandibular region and neck. Features associated with spread included severity of blepharospasm, family history of dystonia, depression, and anxiety.
CONCLUSIONS
This study provides a comprehensive summary of motor and non-motor features of blepharospasm, along with novel insights into factors that may be responsible for its poor diagnostic recognition and natural history.

The Journal of Headache and Pain Feb 2024To compare the outcomes associated with the use of lasmiditan, rimegepant, ubrogepant, and zavegepant for the acute management of migraine headaches. (Meta-Analysis)
Meta-Analysis Review
Comparison of effectiveness and safety of lasmiditan and CGRP-antagonists for the acute treatment of migraine in adults: systematic review and network meta-analysis of randomised trials.
OBJECTIVE
To compare the outcomes associated with the use of lasmiditan, rimegepant, ubrogepant, and zavegepant for the acute management of migraine headaches.
METHODS
We searched four electronic databases from database inception to August 31, 2023, to identify randomized controlled trials (RCTs) that report efficacy and safety for the acute treatment of migraine. The risk of bias in the included RCTs was evaluated according to the Cochrane tool, and the certainty of evidence using the CINeMA approach. We conducted frequentist network meta-analyses (NMA) to summarise the evidence. Data were analyzed using R-4.3.1.
RESULTS
A total of 18 eligible studies including 10 different types of interventions with 22,429 migraine patients were included. NMA results showed that compared to ubrogepant (25 mg and 50 mg) and zavegepant, lasmiditan (100 mg and 200 mg) exhibits an elevated probability of achieving pain relief within a 2-hour interval. Similarly, relative to zavegepant, rimegepant (75 mg) and ubrogepant (50 mg and 100 mg) demonstrate an enhanced likelihood of sustaining pain relief over a 24-hour period. Furthermore, in contrast to ubrogepant (25 mg) and lasmiditan (50 mg), rimegepant (75 mg) presents a heightened probability of achieving freedom from photophobia within 2 h. Regarding safety, lasmiditan carries the highest risk of adverse events, which are associated with an increased incidence of adverse effects, including dizziness, somnolence, asthenia, paresthesia, and fatigue.
CONCLUSIONS
In this NMA, a spectrum of evidence ranging from very low to high levels underscores the favorable efficacy and tolerability of rimegepant 75 mg and ubrogepant 100 mg, positioning them as potential candidates for the acute management of migraine. Concurrently, lasmiditan (100 mg and 200 mg) exhibits notable efficacy, albeit accompanied by an increased susceptibility to adverse events. These findings should still be approached with caution, primarily due to the intrinsic limitations associated with indirect comparisons.

BACKGROUND
Visual Snow Syndrome is a recently recognized neurological condition presenting, continuous, tiny dots across the entire visual field, accompanied by nyctalopia, photophobia and palinopsia that persist for months. It may be part of migraine aura spectrum, yet its definition is still questionable. Diagnostic criteria for Visual Snow Syndrome are included in the supplemental material of ICHD-3. We aimed to summarize recent data to improve the understanding of Visual Snow Syndrome.
METHODS
After presenting four new cases, we conducted a PRISMA systematic search in PubMed/MEDLINE and Embase databases using the keyword "visual snow" with specific inclusion and exclusion criteria.
RESULTS
From the 855 articles identified 30 were included for the qualitative analysis. These reports covered five aspects related to Visual Snow Syndrome: epidemiology, clinical features, comorbidities, pathophysiology, and treatment. We found limited data concerning Visual Snow Syndrome's epidemiology (one study). Clinical presentation (22 articles) and the comorbidities (migraine with aura and tinnitus most often, five reports) are described in detail. The pathophysiology of Visual Snow Syndrome is only approached with hypotheses, but several neuroimaging studies have been identified (seven articles). Treatment is based on single case reports only.
CONCLUSION
Data for Visual Snow Syndrome are few and not strong enough to support Visual Snow Syndrome as a medical identity. Further investigation is needed.

Review
INTRODUCTION
Subarachnoid haemorrhage (SAH) may arise spontaneously or as a result of trauma. Spontaneous SAH accounts for about 5% of all strokes. Ruptured aneurysms are the cause of 85% of spontaneous SAH. The most characteristic clinical feature is sudden-onset severe headache. Other features include vomiting, photophobia, and focal neurological deficit or seizures, or both. As the headache may have insidious onset in some cases, or may even be absent, a high degree of suspicion is required to diagnose SAH with less typical presentations.
METHODS AND OUTCOMES
We conducted a systematic review, aiming to answer the following clinical question: What are the effects of surgical treatments for people with confirmed aSAH? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review).
RESULTS
At this update, searching of electronic databases retrieved 82 studies. After deduplication and removal of conference abstracts, 47 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 33 studies and the further review of 14 full publications. Of the 14 full articles evaluated, one systematic review, one RCT, and four further reports were added at this update. We performed a GRADE evaluation for six PICO combinations.
CONCLUSIONS
In this systematic overview, we categorised the efficacy for one comparison based on information about the effectiveness and safety of endovascular coiling versus surgical clipping.

American Journal of Ophthalmology Mar 2021To evaluate safety and efficacy of topical cysteamine ophthalmic solution for corneal cystinosis. (Meta-Analysis)
Meta-Analysis
PURPOSE
To evaluate safety and efficacy of topical cysteamine ophthalmic solution for corneal cystinosis.
METHODS
Seven databases were searched (PubMed, OVID, EMBASE, Web of Science, Cochrane Central, Google Scholar, and ClinicalTrials.gov) for relevant studies, using appropriate keywords. Comparative observational studies and randomized controlled trials comparing cysteamine with control or other formulations for treatment of corneal or ophthalmic cystinosis were included. Outcome measurements were improvement or response to therapy, change in corneal cystine crystal score (CCCS), in vivo confocal microscopy score (IVCM), cystine crystal depth, contrast sensitivity (CS), photophobia score, and safety.
DESIGN
Systematic review and meta-analysis.
RESULTS
Seven studies were included. Compared to placebo and control, the cysteamine arm was better in terms of improvements and responses to therapy (2 studies showed a risk ratio [RR] of 16; 95% confidence interval [CI]: 2.30-111.37) and crystal density score (1 study showed a mean difference [MD] of -0.80; 95% CI: -1.56 to -0.04). No significant differences were observed in terms of improvement in CS (1 study showed an RR of 7.00; 95% CI: 0.47-103.27). Compared to cystamine, cysteamine showed benefits in terms of crystal density score (MD -0.94; 95% CI: -1.64 to -0.24). Compared to a newer formulation, the standard formulation (cysteamine [Cystaran]; 0.55% cysteamine hydrochloride + benzalkonium chloride 0.01%) performed better in terms of decreasing CCCS. Another newer, viscous formulation, Cystadrops, performed better than the standard formulation in terms of change in CCCS, IVCM score, corneal crystal depth, and photophobia score; however, local adverse effects and blurring were higher in the group receiving Cystadrops.
CONCLUSIONS
Conventional cysteamine (0.1% to 0.3%) performed better than placebo (control) in terms of response to therapy. In terms of decreasing corneal cystine density, cysteamine (0.55%) was better than cystamine (0.55%), and the viscous Cystadrops (0.55%) was better than the standard formulation (0.1%).
