Ice Pick Headache
Abstract Ice pick headache, also called idiopathic or primary stabbing headache, is a unique headache type associated with ultra-brief stabs of pain, most commonly in the frontal or temporal area. It occurs predominantly in women and is estimated to affect 2–35 % of the population. Unlike other headache types of short duration, such as short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), ice pick headache is not associated with any cranial autonomic symptoms but has been known to occur with nausea, vomiting, photophobia, and dizziness. It exists in two forms: primary ...

What Genetics are Associated with Multiple Sclerosis?
Discussion Multiple sclerosis (MS) is “a chronic degenerative, often episodic disease of the central nervous system marked by patchy destruction of the myelin that surrounds and insulates nerve fibers, usually appearing in young adulthood and manifested by one or more mild to severe neural and muscular impairments, as spastic weakness in one or more limbs, local sensory losses, bladder dysfunction, or visual disturbances.” It is a chronic disease and therefore symptoms must occur more than once. The first episode is called an acute demyelinating attack. Fifteen to forty-five percent of children with their first...

Oculomotor Nerve Palsy after Herpes Zoster Opthalmicus: A Case Report and Review of Literature (P1.297)
Conclusions: HZO is manifestation of re-activation of herpes zoster with involvement of ophthalmic division of trigeminal nerve. CNIII palsy after HZO is rare, especially with associated pupillary defect. The long term prognosis is felt to be excellent with use of antiviral agents and steroids.Disclosure: Dr. Shaker has nothing to disclose. Dr. Rai has nothing to disclose.

Herpes zoster ophthalmicus and varicella zoster virus vasculopathy
ABSTRACT Herpes zoster (HZ) corresponds to the reactivation of varicella zoster virus (VZV). Among adults, the ophthalmic division of the trigeminal nerve is one of the most common sites of involvement. Vasculopathy caused by HZ is associated with significant morbidity and mortality, affecting structures such as the brain, which can lead to stroke. In this review, we analyzed the epidemiological and clinical aspects of the vascular involvement of VZV, focusing on the peculiarities of its association with ocular HZ. A review of the available literature indicated that ocular involvement of HZ was a risk factor for vasculopat...

Prevention of Herpes Zoster and its complications: from the clinic to the real life experience with the vaccine.
Abstract The Herpes Zoster (HZ) is an acute viral illness characterized by a vesicular rash, with unilateral distribution, which can eventually cause severe complications, such as the post-herpetic neuralgia (PHN), the ophthalmic zoster, stroke or other neurological complications. In Europe, an incidence between 2.0 and 4.6 cases per 1,000 persons-year is estimated, with an increase after 50 years of age. Currently, the therapeutic options for HZ are only partially effective to limit the acute phase, while the management of complications is frequently complex and not satisfactory. The overall burden of the disease...

What Causes Hyperammonemia?
Discussion Reye’s syndrome (RS)is named for Dr. Douglas Reye who along with Drs. G. Morgan and J. Baral described encephalopathy and fatty accumulation and degeneration in children in a 1963 Lancet article. RS usually affects children but can occur at all ages. All organs can be affected but the liver and brain are primarily affected causing liver failure and encephalopathy as toxic metabolites (especially ammonia) accumulate, and intracranial hypertension and cerebral edema occurs. As the ammonia levels begin to rise (> 100 mg/dL) patients lose their appetite, have nausea and emesis and mental status changes whic...

Burden of herpes simplex virus encephalitis in the United States
AbstractHerpes simplex virus encephalitis (HSVE) is a disease of public health concern, but its burden on the healthcare of United States has not been adequately assessed recently. We aimed to define the incidence, complications and outcomes of HSVE in the recent decade by analyzing data from a nationally representative database. Healthcare Cost and Utilization Project databases were utilized to identify patients with primary discharge diagnosis of HSVE. Annual hospitalization rate was estimated and several preselected inpatient complications were identified. Regression analyses were used to identify mortality predictors. ...

Herpes zoster ophthalmicus with associated vasculopathy causing stroke. Antia, Camila; Persad, Leah; Alikhan, Ali
Varicella zoster virus (VZV) is an exclusively human, double-stranded DNA virus. Primary infection causes varicella (chickenpox); later the virus becomes dormant in the dorsal root, cranial nerve, and autonomic ganglia along the entire span of the nervous system, retaining the capacity to reactivate and cause a variety of dermal and neurological complications. Recently there has been increasing recognition, both clinically and epidemiologically, of the relationship between VZV and subsequent strokes. Herein, we describe a case of a previously healthy individual with reactivation of VZV causing herpes zoster opthtalmicus al...

What Causes Microcephaly?
Discussion Microcephaly is usually defined as an occipitofrontal head circumference (OFC) more than 2 standard deviations (SD) below the mean for sex, age and ethnicity. Severe microcephaly is used for OFC < 3 standard deviations. Rates of microcephaly range from 0.5-12 patients/10,000 live births. The OFC should be measured at every well child visit and at other opportunities and plotted on standard growth charts. The OFC is measured using a nonelastic tape measure around the largest part of the head with the tape measure held above the eyebrows and ears. It is a highly reproducible measurement. There are several diff...
