Review
BACKGROUND
Infectious mononucleosis is common among adolescents and young adults. Although the majority of cases resolve spontaneously, life-threatening manifestations, and complications have been recognised.
OBJECTIVE
The purpose of this article is to familiarize clinicians with the clinical manifestations, evaluation, diagnosis, and management of infectious mononucleosis.
METHODS
A search was conducted in October 2022 in PubMed Clinical Queries using the key terms "infectious mononucleosis" OR "Epstein-Barr virus" OR "EBV". The search strategy included all clinical trials, observational studies, and reviews published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the aforementioned search was used in the compilation of the present article.
RESULTS
Infectious mononucleosis, caused by Epstein-Barr virus, most commonly affects adolescents and adults aged 15 to 24 years. Epstein-Barr virus is transmitted primarily in saliva. Infectious mononucleosis is characterized by a triad of fever, tonsillar pharyngitis, and lymphadenopathy. Fatigue may be profound but tends to resolve within three months. Periorbital and/or palpebral edema, typically bilateral, occurs in one-third of patients. Splenomegaly and hepatomegaly occur in approximately 50% and 10% of cases, respectively. A skin rash, which is usually widely scattered, erythematous, and maculopapular, occurs in approximately 10 to 45% of cases. Peripheral blood leukocytosis is observed in most patients; lymphocytes make up at least 50% of the white blood cell differential count. Atypical lymphocytes constitute more than 10% of the total lymphocyte count. The classic test for infectious mononucleosis is the demonstration of heterophile antibodies. The monospot test is the most widely used method to detect the serum heterophile antibodies of infectious mononucleosis. When confirmation of the diagnosis of infectious mononucleosis is required in patients with mononucleosis-like illness and a negative mono-spot test, serologic testing for antibodies to viral capsid antigens is recommended. Infectious mononucleosis is a risk factor for chronic fatigue syndrome. Spontaneous splenic rupture occurs in 0.1 to 0.5% of patients with infectious mononucleosis and is potentially life-threatening. Treatment is mainly supportive. Reduction of activity and bed rest as tolerated are recommended. Patients should be advised to avoid contact sports or strenuous exercise for 8 weeks or while splenomegaly is still present. Most patients have an uneventful recovery.
CONCLUSION
Infectious mononucleosis is generally a benign and self-limited disease. Prompt diagnosis is essential to avoid unnecessary investigations and treatments and to minimize complications. Splenic rupture is the most feared complication. As avoiding exposure to EBV is almost impossible, the most effective way to prevent EBV infection and infectious mononucleosis is the development of an effective, safe, and affordable EBV vaccine that can confer life-long immunity.

Current Opinion in Ophthalmology Jun 2024To highlight the clinical features of mpox with an emphasis on ocular manifestations and to review treatment options for this re-emerging infectious disease.
PURPOSE OF REVIEW
To highlight the clinical features of mpox with an emphasis on ocular manifestations and to review treatment options for this re-emerging infectious disease.
RECENT FINDINGS
Ocular involvement of mpox varies by clade. The most recent 2022 outbreak appears to be associated with fewer conjunctivitis cases compared to previous outbreaks. However, the ocular findings occurring during this newly emerging clade can be visually threatening and include cases of keratitis, rapidly progressing scleritis, and necrotizing periorbital rashes.
SUMMARY
Ocular mpox is an important clinical feature of systemic mpox virus (MPXV) infection. Heightened clinical suspicion allows for a timely diagnosis and the initiation of antiviral treatment, when appropriate. Randomized clinical trials for mpox systemic and ocular treatment efficacy are lacking. Prior clinical experience with smallpox and in-vitro mpox data support the use of systemic antivirals such as tecovirimat, cidofovir, brincidofovir and topical use of trifluridine in ocular mpox management, though treatment-resistant infection can occur and portend a poor prognosis.

Mucocele is a benign, expansile, and oppressive lesion, more common in the frontal and ethmoid sinus and less in the maxillary sinus. Sinus mucocele mainly causes cheek swelling pain and nasal obstruction. In some cases, the paranasal mucocele grows large enough to compress periorbital structures and lead to impaired vision. Generally, mucocele is full of simple mucus, but pathogens can be found if co-infected, which means a poor prognosis. Functional endoscopic sinus surgery is an effective treatment for this disease. Here, the authors report a case that a mucocele occurred in the maxillary sinus, and a fungal ball was also found during the operation, which is a result of Paecilomyces farinosus co-infection.

VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a newly described autoinflammatory entity caused by a UBA-1 gene mutation. Among the most frequent symptoms it produces fever, cytopenias, polychondritis, pulmonary infiltrates and up to 40% ocular involvement such as periorbital edema, uveitis, episcleritis, scleritis and retinal vasculitis. Patients respond to high doses of corticosteroids, however, many end up being refractory to them and to the classic immunosuppressants. We described the case of a 77-year-old male patient with ocular involvement in the form of episcleritis and periorbital edema who was later diagnosed with VEXAS Syndrome. The patient, after failing treatment with immunosuppressants, is currently receiving treatment with oral steroids and tocilizumab. Ophthalmologist must be aware of the ophthalmological affectation of autoinflammatory diseases and especially of this new entity described as the VEXAS Syndrome.

Necrotizing fasciitis (NF) is an aggressive and potentially life-threatening infection of the superficial fascia and surrounding skin, fat, fascia, muscle, and other soft tissue structures. Here, we outline the rare case of a 26-year-old man with a periorbital Streptococcus pyogenes A NF infection. Our case report underscores a unique instance of periorbital NF, distinctively presenting without any predisposing risk factors, shedding light on its presentation, treatment, and pathophysiology.
