    Eyelid and Orbital Infections

    27 Eyelid and Orbital Infections Ayub Hakim Department of Ophthalmology, Western Galilee - Nahariya Medical Center, Nahariya, Israel 1. Introduction The major infections of the ocular adnexal and orbital tissues are preseptal cellulitis and orbital cellulitis. They occur more frequently in children than in adults. In Schramm's series of 303 cases of orbital cellulitis, 68% of the patients were younger than 9 years old and only 17% were older than 15 years old. Orbital cellulitis is less common, but more serious than preseptal. Both conditions happen more commonly in the winter months when the incidence of paranasal sinus infections is increased. There are specific causes for each of these types of cellulitis, and each may be associated with serious complications, including vision loss, intracranial infection and death. Studies of orbital cellulitis and its complication report mortality in 1- 2% and vision loss in 3-11%. In contrast, mortality and vision loss are extremely rare in preseptal cellulitis. 1.1 Definitions Preseptal and orbital cellulites are the most common causes of acute orbital inflammation. Preseptal cellulitis is an infection of the soft tissue of the eyelids and periocular region that is localized anterior to the orbital septum outside the bony orbit. Orbital cellulitis ( 3.5 per 100,00 ) is an infection of the soft tissues of the orbit that is localized posterior to the orbital septum and involves the fat and muscles contained within the bony orbit. Both types are normally distinguished clinically by anatomic location. 1.2 Pathophysiology The soft tissues of the eyelids, adnexa and orbit are sterile. Infection usually originates from adjacent non-sterile sites but may also expand hematogenously from distant infected sites when septicemia occurs.

We aimed to describe demographic data, clinical presentation, predisposing factors, identified microorganisms, choice of antibiotics and management in children with orbital cellulitis treated in a tertiary care centre in Malaysia. METHODS A retrospective review was performed on children with orbital cellulitis aged below 18 years who were admitted to Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2013 and December 2017. RESULTS A total of 14 paediatric patients fulfilling the diagnostic criteria for orbital cellulitis were included. Their mean age was 6.5 ± 1.2 years. Boys were more likely to have orbital cellulitis than girls (71.4% vs. 28.6%). Involvement of both eyes was observed in 14.3% of the patients. Sinusitis (28.6%) and upper respiratory tract infection (21.4%) were the most common predisposing causes. Staphylococcus aureus (28.6%) was the leading pathogen. Longer duration of hospitalisation was observed in those infected with methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei. 10 (71.4%) patients were treated with a combination of two or three antibiotics. In this series, 42.9% had surgical interventions. CONCLUSION Young boys were found to be more commonly affected by orbital cellulitis than young girls.

    Journal of Microbiology and Infectious Diseases / 2014; 4 (3): 123-127 JMID doi: 10.5799/ahinjs.02.2014.03.0154 REVIEW ARTICLE Preseptal and orbital cellulitis Emine Akçay, Gamze Dereli Can, Nurullah Çağıl Yıldırım Beyazıt Univ. Medical Faculty Atatürk Training and Research Hospital Dept. of Ophthalmology, Ankara, Turkey ABSTRACT Preseptal cellulitis (PC) is defined as an inflammation of the eyelid and surrounding skin, whereas orbital cellulitis (OC) is an inflammation of the posterior septum of the eyelid affecting the orbit and its contents. Periorbital tissues may become infected as a result of trauma (including insect bites) or primary bacteremia. Orbital cellulitis generally occurs as a complication of sinusitis. The most commonly isolated organisms are Staphylococcus aureus, Streptococcus pneu- moniae, S. epidermidis, Haempphilus influenzae, Moraxella catarrhalis and S. pyogenes. The method for the diagnosis of OS and PS is computed tomography. Using effective antibiotics is a mainstay for the treatment of PC and OC. There is an agreement that surgical drainage should be performed in cases of complete ophthalmoplegia or significant visual impairment or large abscesses formation. This infections are also at a greater risk of acute visual loss, cavernous sinus thrombosis, meningitis, cerebritis, endo- phthalmitis, and brain abscess in children. Early diagnosis and appropriate treatment are crucial to control the infection. Diagnosis, treatment, management and complications of PC and OC are summarized in this manuscript.

    EML Application on Eye Infections

    EML Application on eye infections Applicants: Dr. Mark Loeb, Dr. Dominik Mertz McMaster University Correspondence: Dr. Mark Loeb, McMaster University, 1280 Main St West, MDCL 3200, Hamilton, Ontario, Canada L8S 4K1; [email protected] 1 Background The WHO Essential Medicine List (EML) lists the most efficacious and safe medicines to treat illnesses that are considered high priority, including antibiotics. However, most antibiotics were listed decades ago and a comprehensive review of all the antibiotics listed over the past 40 years has never been done. Given increasing concerns about overuse of antibiotics, the emergence of antimicrobial resistance and the need to guarantee prompt access to highly beneficial treatments, revising and updating the list is an important priority. Applications for revisions to the Model List are accepted every 2 years and are by single agent. However, similarly to what has been done for cancer in 2015, a syndrome-based approach was agreed as the best option. We have revised the list based on common syndromes to date and have now done this for eye infections. All potentially relevant antibiotics for use across low, middle and high-income countries, were considered. The working group and the EML Secretariat a priori reasoned on the guiding principles to prioritize the selection of antibiotics: safety and efficacy, resistance, feasibility, parsimony. As in our previous work on the original 21 syndromes [1], this review of the evidence was supplemented by a systematic search and synthesis of clinical practice guidelines. We placed a relative high value on evidence and guideline recommendations that can be applicable to a majority of patients and settings.

I am a second year medical student at the University of Alberta. This podcast was developed with the help of Dr. Melanie Lewis a Pediatrician and Professor at the University of Alberta and Dr. Catherine Morgan a Pediatric Nephrologist and Associate Professor at the University of Alberta. This podcast will help you develop an approach to a child presenting with periorbital edema. Objectives ● Determine the key differential diagnoses for the presentation of periorbital edema ● Identify historical aspects, physical exam findings and diagnostic studies that can help determine the etiology of the periorbital edema ● Discuss the key points on history and physical exam that differentiate periorbital cellulitis from orbital cellulitis ● Outline the management of periorbital cellulitis and orbital cellulitis Cases Case 1: A 5-year old boy presents with rapid onset bilateral eye swelling. He has had no changes in the quality of his vision. His history includes a recent upper respiratory tract infection 2 weeks ago. Case 2: A 13-year-old boy presents to the emergency department with his left eye swollen shut. He came in straight from his baseball tournament. Upon examination, there were no changes in the quality of his vision.
