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.

Review
Tension-type headache (TTH) and migraine are two common primary headaches distinguished by clinical characteristics according to the 3 edition of the International Classification of Headache Disorders. Migraine is identified by specific features such as being more prevalent in females, being aggravated by physical activity, certain genetic factors, having photophobia, phonophobia, nausea, vomiting, or aura, and responding to specific drugs. Nonetheless, TTH and migraine share some common characteristics, such as onset occurring in the 20 s, and being triggered by psychological factors like stress, moderate pain severity, and mild nausea in chronic TTH. Both conditions involve the trigeminovascular system in their pathophysiology. However, distinguishing between TTH and migraine in clinical practice, research, and epidemiological studies can be challenging, as there is a lack of specific diagnostic tests and biomarkers. Moreover, both conditions may coexist, further complicating the diagnostic process. This review aims to explore the similarities and differences in the pathophysiology, epidemiology, burden and disability, comorbidities, and responses to pharmacological and non-pharmacological treatments of TTH and migraine. The review also discusses future research directions to address the diagnostic challenges and improve the understanding and management of these conditions.

Review
Cervicogenic headache, described almost 100 years ago, only had its clinical awakening at the end of the century with the work of Professor Sjaastad. Its classic definition is the induction of trigeminal symptoms from cervical disorders, thanks to trigeminocervical convergence mechanisms. For this reason, it can manifest several features typical of migraine, leading to diagnostic errors. Classically, subjects complain of fixed unilateral headaches, with cervical onset and trigeminal irradiation, associated with reduced neck mobility and flexion strength. The headache is mild to moderate, described as pulsatile or compressive, accompanied by nausea, vomiting, photophobia, phonophobia, and may present autonomic symptoms and dizziness. The pain duration varies from one day to weeks, and its frequency is unpredictable. A history of whiplash injury is common. The differential diagnosis encompasses migraine and tension-type headache. Management includes physiotherapy rehabilitation, anesthetic blocks, and selectively surgical procedures. In this article, all these aspects were extensively covered.

A 56-year-old man presented to the clinic with episodic headaches for several years which had been worsening over a few months prior to the presentation. He described headache as sharp, stabbing pain around the left eye associated with nausea, vomiting, photophobia, and phonophobia lasting for hours associated with flushing on the left side of the face. The picture of his face during these episodes showed flushing of the left side of the face, ptosis of the right eyelid, and miosis (panel A). Flushing in his face would resolve with the abortion of the headache. At the time of presentation to the clinic, his neurological exam was only significant for mild left eye ptosis and miosis (panels B and C). Extensive workup including MRI brain, cervical spine, thoracic spine, lumbar spine, CTA head and neck, and CT maxillofacial was unremarkable. He had tried several medications in the past including valproic acid, nortriptyline, and verapamil without significant benefit. He was started on erenumab for migraine prophylaxis and was given sumatriptan for abortive therapy following which his headaches improved. The patient was diagnosed with idiopathic left Horner's syndrome and his migraines with autonomic dysfunction would present with unilateral flushing opposite to the site of Horner's presenting as Harlequin syndrome [1, 2].
