1/3. Corneal epithelial keratitis in herpes zoster ophthalmicus: "delayed" and "sine herpete". A non-contact photomicrographic in vivo study in the human cornea.

    PURPOSE: To investigate the origin of corneal epithelial keratitis occurring without accompanying herpes zoster ophthalmicus (HZO) cutaneous rash. methods: Corneal epithelial lesions in seven patients (four with a history of classical HZO with cutaneous rash, one of herpes zoster oticus, and two with no history of herpes zoster, were examined with the slit lamp and photographed by non-contact in vivo photomicrography. The findings were compared with lesions in classical acute HZO. polymerase chain reaction (PCR) was done in three patients. RESULTS: Slit lamp appearance, morphology at higher magnification, and kinetics of the lesions were indistinguishable from classical acute HZO. PCR was positive for varicella-zoster virus dna in all three samples. CONCLUSIONS: The findings strongly suggest that HZO typical corneal epithelial lesions occurring in the absence of cutaneous rash are in fact recurrent episodes of virus shedding. ( info)

2/3. Chronic active VZV infection manifesting as zoster sine herpete, zoster paresis and myelopathy.

    After lumbar-distribution zoster, an HTLV-1-seropositive woman developed chronic radicular sacral-distribution pain (zoster sine herpete), cervical-distribution zoster paresis and thoracic-distribution myelopathy. Detection of anti-varicella zoster virus (VZV) IgM and VZV IgG antibody in cerebrospinal fluid (CSF), with reduced serum/CSF ratios of anti-VZV IgG compared to normal serum/CSF ratios for albumin and total IgG, proved that VZV caused the protracted neurological complications. diagnosis by antibody testing led to aggressive antiviral treatment and a favorable outcome.

3/3. lateral sinus thrombosis associated with zoster sine herpete.

    Herpes zoster results from reactivation of the varicella zoster virus (VZV). zoster sine herpete (ZSH) is an uncommon manifestation of VZV infection and presents with similar symptoms but without the vesicular rash. We describe an unusual case of lateral sinus thrombosis (LST) that developed during the clinical course of ZSH in the C2 distribution. A 55-year-old woman presented with a 3-day history of left temporal and postauricular pain, nausea, vomiting, and mild photophobia. She denied otalgia, otorrhea, and hearing loss. Examination revealed hyperesthesia in the left C2 nerve root distribution without evidence of herpetic rash. A computed tomography scan showed minimal fluid in the left mastoid cavity (not mastoiditis) and thrombus within the left lateral and sigmoid dural sinus. magnetic resonance imaging and magnetic resonance angiogram confirmed these findings. Laboratory studies revealed elevated neurotrophic immunoglobulin g levels to VZV. Hypercoagulable studies were normal. She was subsequently treated with Neurontin, acyclovir, and anticoagulation. Her symptoms improved, and she was discharged 3 days later. LST is generally a complication of middle ear infection. Nonseptic LST, however, may result from dehydration, oral contraceptive use, coagulopathy, or thyroid disease. This unusual case raises the suspicion that thrombosis resulted from VZV associated thrombophlebitis in the ipsilateral cerebral venous sinuses along the second cervical nerve root distribution. A high index of suspicion is necessary in such cases so that a different treatment course can be identified and antiviral medication initiated promptly. ( info)
