Review
IMPORTANCE
Conjunctivitis is a common problem.
OBJECTIVE
To examine the diagnosis, management, and treatment of conjunctivitis, including various antibiotics and alternatives to antibiotic use in infectious conjunctivitis and use of antihistamines and mast cell stabilizers in allergic conjunctivitis.
EVIDENCE REVIEW
A search of the literature published through March 2013, using PubMed, the ISI Web of Knowledge database, and the Cochrane Library was performed. Eligible articles were selected after review of titles, abstracts, and references.
FINDINGS
Viral conjunctivitis is the most common overall cause of infectious conjunctivitis and usually does not require treatment; the signs and symptoms at presentation are variable. Bacterial conjunctivitis is the second most common cause of infectious conjunctivitis, with most uncomplicated cases resolving in 1 to 2 weeks. Mattering and adherence of the eyelids on waking, lack of itching, and absence of a history of conjunctivitis are the strongest factors associated with bacterial conjunctivitis. Topical antibiotics decrease the duration of bacterial conjunctivitis and allow earlier return to school or work. Conjunctivitis secondary to sexually transmitted diseases such as chlamydia and gonorrhea requires systemic treatment in addition to topical antibiotic therapy. Allergic conjunctivitis is encountered in up to 40% of the population, but only a small proportion of these individuals seek medical help; itching is the most consistent sign in allergic conjunctivitis, and treatment consists of topical antihistamines and mast cell inhibitors.
CONCLUSIONS AND RELEVANCE
The majority of cases in bacterial conjunctivitis are self-limiting and no treatment is necessary in uncomplicated cases. However, conjunctivitis caused by gonorrhea or chlamydia and conjunctivitis in contact lens wearers should be treated with antibiotics. Treatment for viral conjunctivitis is supportive. Treatment with antihistamines and mast cell stabilizers alleviates the symptoms of allergic conjunctivitis.

Review
INTRODUCTION
Active trachoma is caused by chronic infection of the conjunctiva by Chlamydia trachomatis, and is the world's leading infectious cause of blindness. Infection can lead to: scarring of the tarsal conjunctiva; inversion of the eyelashes (trichiasis), so that they abrade the cornea; and corneal opacity, resulting in blindness. Trachoma is a disease of poverty, overcrowding, and poor sanitation. Active disease affects mainly children, but adults are at increased risk of scarring.
METHODS AND OUTCOMES
We conducted a systematic overview, aiming to answer the following clinical question: What are the effects of interventions to prevent scarring trachoma by reducing the prevalence of active trachoma? We searched: Medline, Embase, The Cochrane Library and other important databases up to December 2014 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview).
RESULTS
At this update, searching of electronic databases retrieved 170 studies. After deduplication and removal of conference abstracts, 96 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 61 studies and the further review of 35 full publications. Of the 35 full articles evaluated, three previously included systematic reviews were updated, one systematic review and two RCTs were added at this update, and two RCTs and one further report were added the Comment sections. We performed a GRADE evaluation for nine PICO combinations.
CONCLUSIONS
In this systematic overview, we categorised the efficacy for seven interventions based on information about the effectiveness and safety of antibiotics, face washing (alone or plus topical tetracycline), fly control (through the provision of pit latrines, and using insecticide alone or plus antibiotics), and health education.

Allergic rhinitis (AR) is induced by an IgE-mediated immune reaction after allergen exposure. The typical symptoms are itching, nasal discharge, sneezing and nasal obstruction. The diagnosis is based on the concordance between allergic symptoms and diagnostic tests. The skin prick test (SPT) is recommended as the "gold standard" method. First generation H1-antihistamines are widely used for treatment of AR. Intranasal glucocorticosteroids are well tolerated and can be used also in paediatric age. Allergic rhinitis cannot be considered as an isolated pathology. Other atopic diseases (allergic conjunctivitis, atopic eczema, asthma) are commonly associated.

Review
CONTEXT:
Infections are common in contact sports. This review aims to describe the epidemiology, presenting signs and symptoms, treatment guidelines, and regulations for several common infections seen in contact sport athletes. The conditions discussed include bacterial skin infections, herpes simplex virus, molluscum contagiosum, common warts, tinea, scabies, head lice, conjunctivitis, human immunodeficiency virus, hepatitis C virus, and vaccine-preventable illnesses.
EVIDENCE ACQUISITION:
Searches were performed across PubMed and MEDLINE research databases. In addition, general internet search engine results and reviews of reference lists of relevant papers were used to identify additional sources of evidence.
STUDY DESIGN:
Clinical review.
LEVEL OF EVIDENCE:
Level 4.
RESULTS:
The most common infections seen in contact sport athletes include bacterial skin infections, herpes simplex virus, molluscum contagiosum, common warts, tinea, scabies, head lice, conjunctivitis, and vaccine-preventable illnesses. Other infections, including human immunodeficiency virus and hepatitis C, are uncommon but potentially life threatening.
CONCLUSION:
Infections are common in contact sport athletes. The provider who cares for these athletes should be aware of the most common infections and their appropriate management. Early diagnosis and appropriate clinical management are important for treating the infected athlete, minimizing risk of transmission, minimizing time lost from competition, and preventing large outbreaks.

Randomized Controlled Trial
Safety of tralokinumab in adult patients with moderate-to-severe atopic dermatitis: pooled analysis of five randomized, double-blind, placebo-controlled phase II and phase III trials.
BACKGROUND
Tralokinumab is a fully human monoclonal antibody that neutralizes the activity of interleukin-13, a key pathogenic driver of atopic dermatitis (AD). Clinical trials including adults with moderate-to-severe AD, of up to 52 weeks' duration, showed tralokinumab was efficacious and well tolerated.
OBJECTIVES
To characterize the safety profile of tralokinumab for the treatment of moderate-to-severe AD.
METHODS
Safety and laboratory measures were assessed in pooled analyses of phase II and III placebo-controlled clinical trials of tralokinumab in moderate-to-severe AD (NCT02347176, NCT03562377, NCT03131648, NCT03160885, NCT03363854).
RESULTS
In total, 2285 patients were randomized in the initial treatment periods up to 16 weeks (1605 tralokinumab, 680 placebo). The frequencies of any adverse event (AE) were 65·7% for tralokinumab and 67·2% for placebo. The respective rates were 640 and 678 events per 100 patient-years of exposure (ep100PYE); rate ratio 1·0, 95% confidence interval (CI) 0·9-1·1. Serious AEs occurred in 2·1% of patients with tralokinumab and 2·8% with placebo (7·4 and 11·9 ep100PYE; rate ratio 0·7, 95% CI 0·4-1·2). The most common AEs occurring at a higher frequency and rate with tralokinumab vs. placebo were: viral upper respiratory tract infection (15·7% vs. 12·2%; 65·1 vs. 53·5 ep100PYE); upper respiratory tract infection (5·6% vs. 4·8%; 20·8 vs. 18·5 ep100PYE); conjunctivitis (5·4% vs. 1·9%; 21·0 vs. 6·9 ep100PYE); and injection-site reaction (3·5% vs. 0·3%; 22·9 vs. 4·0 ep100PYE). Some events in safety areas of interest occurred at a lower frequency and rate with tralokinumab vs. placebo: skin infections requiring systemic treatment (2·6% vs. 5·5%; 9·7 vs. 22·8 ep100PYE), eczema herpeticum (0·3% vs. 1·5%; 1·2 vs. 5·2 ep100PYE), opportunistic infections (3·4% vs. 4·9%; 13·0 vs. 21·3 ep100PYE) and serious infections (0·4% vs. 1·1%; 1·3 vs. 3·7 ep100PYE). AEs did not increase with continued maintenance and open-label treatment, including rates of common or serious AEs and AEs leading to study drug discontinuation. No clinically meaningful changes in mean laboratory measures were observed with treatment up to 1 year.
CONCLUSIONS
Across the AD population pool from five clinical trials, tralokinumab was well tolerated, with consistent safety findings during treatment of patients with moderate-to-severe AD. The safety profile during prolonged tralokinumab treatment was consistent with that during the initial treatment period; the frequency of events did not increase over time. What is already known about this topic? Tralokinumab is a fully human monoclonal antibody that specifically neutralizes interleukin-13, a key cytokine driving skin inflammation and epidermal barrier dysfunction in atopic dermatitis (AD). In clinical trials in moderate-to-severe AD, tralokinumab provided significant and early improvements in the extent and severity of AD and was well tolerated, with an overall safety profile comparable with placebo over 52 weeks. What does this study add? We report the frequency and rate of adverse events (AEs) from pooled observations of over 2000 patients from five phase II and phase III placebo-controlled clinical trials of tralokinumab in moderate-to-severe AD. During initial treatment up to 16 weeks, the frequencies of any AE and of serious AEs were similar for tralokinumab and placebo. AE rates did not increase with continued treatment up to 52 weeks. Common AEs occurring more frequently with tralokinumab vs. placebo were viral and upper respiratory tract infection, conjunctivitis and injection-site reaction. Some events occurred at a lower frequency and rate with tralokinumab vs. placebo, such as skin infections requiring systemic treatment, eczema herpeticum and opportunistic and serious infections. No clinically meaningful changes in mean laboratory measures were observed.

Review
The prevalence of ocular surface immunopathologies is enhanced in the elderly. This increased prevalence has been attributed to age-related dysregulation of innate and adaptive immune system responses. Age-related changes in ocular surface immunity have similar and distinct characteristics to those changes seen in other mucosal tissues. This mini review provides a brief outline of key findings in the field of ocular ageing, draws comparisons with other mucosal tissues and, finally, discusses age-related changes in the context of immunopathogenesis of infectious keratitis and dry eye disease, two of the most common inflammatory disorders of the ocular surface.

BACKGROUND
Viral conjunctivitis (pink eye) can be highly contagious and is of public health importance. There remains significant debate whether SARS-CoV-2 can present as a primary conjunctivitis. The aim of this study was to identify pathogens associated with outpatient infectious conjunctivitis during the COVID-19 Delta surge.
METHODS
This prospective study was conducted in the spring and summer months of 2021. 106 patients with acute conjunctivitis who presented to the Aravind Eye Center in Madurai, India were included. One anterior nasal swab and one conjunctival swab of each eye were obtained for each enrolled patient. Samples were subsequently processed for unbiased metagenomic RNA deep sequencing (RNA-seq). Outcomes included clinical findings and codetection of other pathogens with SARS-CoV-2 in patients with conjunctivitis.
RESULTS
Among the 13 patients identified with human coronavirus RNA fragments in their swabs, 6 patients had SARS-CoV-2 infection, 5 patients had coinfections of SARS-CoV-2 and human adenovirus (HAdV), 1 patient had a coinfection with human coronavirus OC43 and HAdV, and 1 patient had a coinfection of Vittaforma corneae and SARS-CoV-2. 30% had bilateral disease and symptoms on presentation. Petechial hemorrhage was noted in 33% of patients with SARS-CoV-2 infection. No patients with SARS-CoV-2 or SARS-CoV-2 and HAdV infections had subepithelial infiltrates on presentation. All patients denied systemic symptoms.
CONCLUSIONS
Among the patients presented with conjunctivitis associated with human coronavirus infection, over 50% of the patients had co-infections with other circulating pathogens, suggesting the public-health importance of broad pathogen testing and surveillance in the outpatient conjunctivitis population.

Review
INTRODUCTION
Active trachoma is caused by chronic infection of the conjunctiva by Chlamydia trachomatis, and is the world's leading infectious cause of blindness. Infection can lead to scarring of the tarsal conjunctiva, inversion of the eyelashes so that they abrade the cornea (trichiasis), and corneal opacity, leading to blindness. Trachoma is a disease of poverty, overcrowding, and poor sanitation. Active disease affects mainly children, but adults are at increased risk of scarring.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of interventions to prevent scarring trachoma by reducing the prevalence of active trachoma? What are the effects of eye lid surgery for entropion and trichiasis? We searched: Medline, Embase, The Cochrane Library and other important databases up to January 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 23 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics, face washing (alone or plus topical tetracycline), fly control (through the provision of pit latrines, and using insecticide), health education, and lid surgery (bilamellar tarsal rotation, or tarsal advance and rotation).

Meta-Analysis Review
BACKGROUND
Trachoma is the leading infectious cause of blindness. The World Health Organization (WHO) recommends eliminating trachomatous blindness through the SAFE strategy: Surgery for trichiasis, Antibiotic treatment, Facial cleanliness and Environmental hygiene. This is an update of a Cochrane review first published in 2003, and previously updated in 2006.
OBJECTIVES
To assess the effects of interventions for trachomatous trichiasis for people living in endemic settings.
SEARCH METHODS
We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2015, Issue 4), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to May 2015), EMBASE (January 1980 to May 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 7 May 2015. We searched the reference lists of included studies to identify further potentially relevant studies. We also contacted authors for details of other relevant studies.
SELECTION CRITERIA
We included randomised trials of any intervention intended to treat trachomatous trichiasis.
DATA COLLECTION AND ANALYSIS
Three review authors independently selected and assessed the trials, including the risk of bias. We contacted trial authors for missing data when necessary. Our primary outcome was post-operative trichiasis which was defined as any lash touching the globe at three months, one year or two years after surgery.
MAIN RESULTS
Thirteen studies met the inclusion criteria with 8586 participants. Most of the studies were conducted in sub-Saharan Africa. The majority of the studies were of a low or unclear risk of bias.Five studies compared different surgical interventions. Most surgical interventions were performed by non-physician technicians. These trials suggest the most effective surgery is full-thickness incision of the tarsal plate and rotation of the terminal tarsal strip. Pooled data from two studies suggested that the bilamellar rotation was more effective than unilamellar rotation (OR 0.29, 95% CI 0.16 to 0.50). Use of a lid clamp reduced lid contour abnormalities (OR 0.65, 95% CI 0.44 to 0.98) and granuloma formation (OR 0.67, 95% CI 0.46 to 0.97). Absorbable sutures gave comparable outcomes to silk sutures (OR 0.90, 95% CI 0.68 to 1.20) and were associated with less frequent granuloma formation (OR 0.63, 95% CI 0.40 to 0.99). Epilation was less effective at preventing eyelashes from touching the globe than surgery for mild trichiasis, but had comparable results for vision and corneal change. Peri-operative azithromycin reduced post-operative trichiasis; however, the estimate of effect was imprecise and compatible with no effect or increased trichiasis (OR 0.85, 95% CI 0.63 to 1.14; 1954 eyes; 3 studies). Community-based surgery when compared to health centres increased uptake with comparable outcomes. Surgery performed by ophthalmologists and integrated eye care workers was comparable. Adverse events were typically infrequent or mild and included rare postoperative infections, eyelid contour abnormalities and conjunctival granulomas.
AUTHORS' CONCLUSIONS
No trials were designed to evaluate whether the interventions for trichiasis prevent blindness as an outcome; however, several found modest improvement in vision following intervention. Certain interventions have been shown to be more effective at eliminating trichiasis. Full-thickness incision of the tarsal plate and rotation of the lash-bearing lid margin was found to be the best technique and is preferably delivered in the community. Surgery may be carried out by an ophthalmologist or a trained ophthalmic assistant. Surgery performed with silk or absorbable sutures gave comparable results. Post-operative azithromycin was found to improve outcomes where overall recurrence was low.
