Kingella kingae had rarely been reported as a causative organism for corneal ulcer and had not been described before in vernal keratoconjunctivitis (VKC). Generally regarded as commensals of respiratory tract particularly in young children, it had however been isolated from the corneal ulcer scraping of both adult and children. We report a case of bacterial ulcer with isolation of Kingella kingae from the corneal scraping in a young child with underlying VKC.

Pathogens and allergens are deemed as two contrasting facets of host immune status, deficiency and exuberant. In silico domain analysis of a diverse panel of pathogen and allergen proteins has revealed the shortcoming of this notion. Both the pathogen and allergen proteins elicit immune activation, with the outcome of immune agitation depending on the pathogen strain, allergen exposure duration, and host factors. Pathogens can replicate within the host and constantly irritate the immune system, leading to blood coagulation, respiratory collapse and death...

PURPOSE: The disease concept of sick building syndrome (SBS) is still unclear. Ocular mucous membrane irritation is one of the major symptoms of SBS. However, the immunological aspects of the ocular complications of SBS are not yet clarified. The clinical and allergological aspects of SBS cases with ocular disorders with special reference to allergic conjunctival diseases (ACD) were analyzed, especially with respect to local immunological features. METHODS: Twelve cases of SBS with ocular findings and 49 cases of ACD (allergic conjunctivitis [AC], atopic keratoconjunctivitis [AKC], and vernal keratoconjunctivitis [VKC]) for comparison were evaluated...

INTRODUCTION: Vernal keratoconjunctivis (VKC) is a severe form of pediatric ocular allergy, characterized by acute and chronic corneoconjunctival inflammation that may lead to visual sequelae. Although topical immunosuppressive drugs such as cyclosporine are usually effective, some severe forms may be refractory and require prolonged steroid therapy. Very few papers report the use of omalizumab in VKC in the literature. In the present study, we describe our clinical experience with omalizumab in severe VKC children...

BACKGROUND: Vernal keratoconjunctivitis (VKC) is a chronic and often severe bilateral conjunctivitis. VKC etiology still remains unclear although endocrine, genetic, neurogenic and environmental factors have been implicated. Vitamin D is a fat-soluble prohormone whose main function is the regulation of calcium and phosphate metabolism. The aim of this study was to evaluate serum vitamin D in children affected by VKC compared to the healthy children and investigate the relationship between its levels and disease severity...

Vernal keratoconjunctivitis (VKC) is an inflammatory disease of the ocular surface. It commonly occurs in the first decade of life, has a wide geographical distribution, and usually occurs in warm, dry areas. The pathogenesis of VKC seems to have an immune, nervous, and endocrine basis. The most common eye symptoms are itching, discharge, tearing, eye irritation, redness of the eyes, and photophobia. Although VKC generally has a good prognosis, the lack of clarity regarding the origin of the disease makes treatment a challenge for pediatricians and ophthalmologists...

INTRODUCTION: Vernal keratoconjunctivitis (VKC) is a bilateral multi-factorial disease. The pathogenesis of this disease is not obviously determined, but the role of various inflammatory cytokines has been specified. This study has provided a comparison between the level of interleukin-17 (IL17) in the serum and tears of case and control groups, and also the relationship between the level of this interleukin with severity of signs and symptoms of the disease. MATERIALS AND METHODS: This case-control study has been accomplished on 40 individuals (20 healthy people and 20 patients who suffer from VKC) in Al-Zahra Eye Center in 2014...

Vernal keratoconjunctivitis (VKC) is a chronic allergic inflammation of ocular surface involving the tarsal and/or bulbar conjunctiva. Signs of VKC are confined to the conjunctiva and cornea. The skin of the lid remains uninvolved. Here we report a case of 17 year-old male suffering from VKC who develops vitiligo of lid skin and lash poliosis. All ocular and systemic causes of localized skin and lash depigmentation were excluded in our patient by thorough clinical examination and investigations. During regular follow-up for two-year patient did not develop any ocular and systemic illness presenting as vitiligo and poliosis...
