San Diego State University/University of California, CA. We studied the rare case of an older adult with dementia following herpes zoster encephalitis (HZE). This 71-year-old woman presented to us approximately 1 year following resolution of a rapid-onset episode of HZE, and subsequently underwent neuropsychological and neuroimaging examinations. Cognitive assessment revealed impairments in general cognitive functioning, verbal and nonverbal memory, executive functions, speed of information processing, attention/working memory, and motor skills. The patient's neuroimaging data, when compared to a demographically similar healthy control sample (n = 9), demonstrated moderate central and perisylvian brain volume loss, several subcortical lesions in the white matter, and resting state whole brain and hippocampal hypoperfusion. These findings highlight neuropsychological changes evident in a dementia syndrome of this type, and they suggest that early identification and treatment of HZE has implications for the preservation of long-term cognitive functioning.

Part 1: virology, epidemiology, clinical picture, laboratory diagnostics.] [Article in German] Wittek M, Doerr HW, Allwinn R. Institut fur Medizinische Virologie, Universitatsklinikum Frankfurt am Main, Frankfurt am Main, Germany. Varicella-zoster virus (VZV), known as one of the eight human herpesviridae, shows a ubiquitous distribution and is the cause for acute exanthema in childhood (chickenpox). VZV is highly infectious, spread by respiratory droplets and direct contact with fluid in vesicles. As a characteristic of the alpha-herpesviridae, VZV establishes latency in the nucleus of the paraspinal cells. Reactivation of VZV (zoster) is possible in all infected persons, but becomes more common with increasing age and a decline of VZV-specific cell-mediated immunity. Immunocompromised patients and older people (> 50 years) have an increased risk for a severe course of disease. The postherpetic neuralgia (PHN), as one of the most common and feared complications, is defined as a neuropathic pain (burning character), which persists for > 6 weeks after onset of disease and needs adequate antiviral and pain treatment.

The effect of Gunn's intramuscular stimulation for postherpetic neuralgia -A report of 4 cases-. Jung W, Lee BJ, Kim SS, Lee YJ. Department of Anesthesiology and Pain Medicine, Donkang Hospital, Ulsan, Korea. Herpes zoster is the consequence of reactivation of latent varicella zoster virus from dorsal root ganglia. Postherpetic neuralgia (PHN) may be diagnosed when pain persists in a dermatomal pattern long after the vesicular erruption has healed. PHN is a kind of neuropathic pain. The pathophysiology of PHN is uncertain, but neuropathic pain due to denervation supersensitivity may be important to understand the pathophysiology of PHN. Numerous treatment have been introduced for the management of PHN, but no methods that results in complete remission. Gunn's intramuscular stimulation (IMS) is one of the best treatment of chronic pain, especially neuropathic pain. We tried Gunn's IMS for treatment of PHN patients affecting thoracic dermatomes. As a result, the visual analogue scale (VAS) was decreased from 7-8 to 2-3 and the result were satisfactory. The purpose of this case report is to introduce the Gunn's IMS and review our experience for the treatment of PHN. PMID: 20498785 [PubMed - in process] 6. Zhongguo Zhen Jiu. 2010 Mar;30(3):218-20.

[Epub ahead of print] Focal posterior pole viral retinitis. Hazirolan D, Sungur G, Demir N, Kasim R, Duman S. 1st Ophthalmology Department, Ankara Training and Research Hospital, Ministry of Health, Ankara - Turkey. Purpose. To describe the clinical features of an atypical form of viral retinitis in immunocompetent patients. Methods. This was a retrospective noncomparative case series. The charts of 8 patients diagnosed with and treated for focal posterior viral retinitis were reviewed. Clinical and demographic features were evaluated. All the patients had extensive laboratory tests, fundus fluorescein angiography, optical coherence tomography of macula, and polymerase chain reaction of vitreous. Results. All the patients were referred to our Uveitis Service from other hospitals, as their uveitis symptoms deteriorated in spite of treatment. The mean age of 4 male and 4 female patients was 32.1 years (range, 22-42 years). The mean follow-up period was 10 months (range, 6-18 months). All of the patients had unilateral disease. Polymerase chain reaction analysis of vitreous specimen was positive for herpes simplex virus-1 in 5 patients and varicella zoster virus in 3 patients. Retinitis resolved after systemic acyclovir treatment in all patients. Conclusions. Viral etiology must be borne in mind in the differential diagnosis of atypical retinitis. It can be a milder form of viral retinitis like focal viral retinitis, as mentioned in this study. The prognosis of this disease is better than the other forms of necrotizing retinopathies involving a larger area of retina. PMID: 20491048 [PubMed - as supplied by publisher] 9.

Universitats-Augenklinik Freiburg, Freiburg, Germany. florian.birnbaum@uniklinik-freiburg.de Penetrating keratoplasties due to herpetic corneal scars are more often performed compared to persisting Varicella zoster virus infections, which are quite seldom. Penetrating keratoplasties in herpetic corneas are risk keratoplasties due to the vascularisation and the risk of recurrent virus replication. The prognosis in these corneal transplantations has been improved in recent years due to better postoperative medical treatment with virustatics and systemic immunosuppression. Indications for and treatment following penetrating keratoplasty in herpetic eyes are the topics of this review. PMID: 20490994 [PubMed - in process] 10.

Zentrum fur Augenheilkunde, Klinik fur Erkrankungen des vorderen Augenabschnitts, Universitat Duisburg-Essen, Essen, Germany. Daniel.Meller@uk-essen.de Severe infectious corneal ulceration such as herpetic stromal keratitis commonly causes loss of vision and may lead to blindness. Treatment depending on the underlying disease includes antimicrobial medication and the development of surgical strategies to restore the integrity of the corneal ocular surface. Ulcerative herpetic stromal keratitis and/or neurotrophic keratopathy with the risk of corneal perforation are still clinically challenging conditions in ophthalmic surgery of the ocular surface. Since the introduction of newly developed preservation methods, amniotic membrane (AM) functioning as a basement membrane substitute has gained widespread popularity in ocular surface reconstruction. Various ways of clinical application such as the use of AM as a graft, patch or culture substrate and carrier system to expand ocular surface epithelia have been recently reported. In this article, the basis and clinical application of amniotic membrane transplantation for the management of corneal infections with Herpes simplex and Herpes zoster virus are reviewed.

Institut fur Virologie und Antivirale Therapie, Universitatsklinikum Jena, Jena, Germany. Peter.Wutzler@med.uni-jena.de In Germany, a vaccine (Zostavax) to prevent herpes zoster and postherpetic neuralgia (PHN) in adults aged 50 years and older has been available since October 2009. The efficacy of this attenuated high-dose live vaccine was evaluated in a double-blind randomised, placebo-controlled trial involving more than 38,000 immunocompetent adults aged >or= 60 years. Compared to placebo the vaccine reduced the frequency of herpes zoster by 51 % and the incidence of PHN by 67 %. Overall, the burden of illness was reduced by 61 %. The course of diseases occurring among the vaccine recipients was clearly milder and the risk for complications was lower than among the placebo recipients. Although the vaccine efficacy against herpes zoster declined with advancing age of the vaccinees, subjects older than 70 years also benefited from vaccination because the burden of illness was considerably reduced. To the best of our present knowledge the protective effect of zoster vaccine persists for at least 7 years post-vaccination. The need for, or timing of, revaccination has not yet been determined. Zostavax has been well tolerated. It can be concomitantly administered with inactivated influenza vaccine at separate sites. Zoster and pneumococcal vaccines should not be given concomitantly.

Sektion fur Neurologische Schmerzforschung und -therapie, Universitatsklinikum Schleswig-Holstein, Campus Kiel, Kiel, Germany. BACKGROUND: In the last years, new findings from the research on pain diseases and the enhancement of therapeutic options have drastically changed the treatment of postherpetic neuralgia (PHN). This disease, belonging to the neuropathic pain syndromes, needs an adequate pain therapy at an early stage to prevent pain chronicity. DEFINITION AND CLINICAL ATTRIBUTES OF PHN: In 20 % of all cases of herpes zoster, the innervation territory of the trigeminal nerve is affected. A PHN exists by definition in the case of persisting pain in the zoster-affected area 6 months after healing of the zoster eruptions. The incidence of PHN depends on the patient's age: 50 - 75 % of patients in the seventh decade develop PHN after an infection with herpes zoster. The clinical appearance of PHN is characteristic. Three different pain types can be distinguished: 1. spontaneous, constant, burning pain, 2. intermittent sharp, lancinating pain and 3. pain in response to a normally non-painful stimulus (mechanical allodynia). Other phenomena which can be observed are hyp- or anaesthesia, hypalgesia and par- or dysaesthesia. PATHOPHYSIOLOGY OF NEUROPATHIC PAIN: In the last few years, pathomechanisms of individual pain symptoms occurring in PHN have been identified. These include peripheral and central sensitisation as well as spontaneous activity of damaged afferent nociceptive fibres as the consequence of changes in channels on the neuron's membrane. TREATMENT OF PHN: A basic rule in the treatment of neuropathic pain syndromes is that the medication should be taken for at least 2 - 4 weeks before making a final evaluation. Systematic reviews of data from clinical trials of drug therapy for PHN have given distinct indications for antidepressants, antiepileptics, opioid analgesics and topically acting agents. Tricyclic antidepressants act on CNS pain-modulating descending pathways. The antiepileptics gabapentin and pregabalin act on calcium channels on presynaptic terminals of afferent nociceptive neurons in the central nervous system. Carbamazepine and oxcarbazepine may be helpful for some patients, but there is still a lack of controlled trials demonstrating efficacy in the treatment of PHN. Oral oxycodone and tramadol are verifiable effective drugs in PHN. Topically acting agents with verifiable efficacy in PHN are capsaicin and lidocaine, both available in the form of patches for local use. PMID: 20490990 [PubMed - in process] 13.

Department of Microbiology and Immunology, Witebsky Center for Microbial Pathogenesis and Immunology, University at Buffalo SUNY, 138 Farber Hall, Buffalo, NY, 14214, USA, ruyechan@buffalo.edu. Varicella zoster virus (VZV) is the causative agent of chickenpox and shingles. During productive infection the complete VZV proteome consisting of some 68 unique gene products is expressed through interaction of a small number of viral transcriptional activators with the general transcription apparatus of the host cell. Recent work has shown that the major viral transactivator, commonly designated the IE62 protein, interacts with the human Mediator of transcription. This interaction requires direct contact between the MED25 subunit of Mediator and the acidic N-terminal transactivation domain of IE62. A second cellular factor, host cell factor-1, has been shown to be the common element in two mechanisms of activation of the promoter driving expression of the gene encoding IE62. Finally, the ubiquitous cellular transcription factors Sp1, Sp3, and YY1 have been shown to interact with sequences near the VZV origin of DNA replication and in the case of Sp1/Sp3 to influence replication efficiency.

Service d'ophtalmologie CHU Tokoin, Lome, Togo. AIM: The twofold purpose of this study in people living with human immunodeficiency virus (PLHIV/AIDS) and undergoing highly active antiretroviral treatment (HAART) was to determine the prevalence of ocular manifestations and its correlation with CD4 T-cell count. PATIENTS AND METHODS: All patients who attended 2 NGO care centers that manage PLHIV/AIDS in Lome, Togo between August and October 2005 were recruited. CD4 T-cell counts and use of antiretroviral treatment was noted. A thorough eye examination was performed in all cases. RESULTS: A total of 422 PLHIV/SIDA were recruited including 281 who were undergoing HAART. The sex-ratio was 2 female/1 male. Mean age was 34 +/- 2294 years. Involvement of the anterior segment was observed in 36.3% of patients and involvement of the posterior segment in 54.1%. The second most common ocular manifestation was ophthalmic herpes zoster of the anterior segment (19.6%) secondary to conjunctivitis (57.8%). One case of palpebral and conjunctival Kaposi's sarcoma was noted. The most common type of posterior segment involvement was cotton-wool nodules (35.5%). Five cases of CMV retinitis were observed. CONCLUSION: A longitudinal study in PLHIV/AIDS will be needed to better evaluate the correlation between ocular manifestations and CD4 T-cell count. PMID: 20486347 [PubMed - in process] 16.

University of Colorado Denver, Research Complex 2, Mail Stop 8604, 12700 E. 19th Ave., Aurora, CO, 80045, USA, Adriana.Weinberg@ucdenver.edu. Primary varicella-zoster virus (VZV) infection (varicella) induces VZV-specific antibody and VZV-specific T cell-mediated immunity. T cell-mediated immunity, which is detected within 1-2 weeks after appearance of rash, and consists of both CD4 and CD8 effector and memory T cells, is essential for recovery from varicella. Administration of a varicella vaccine also generates VZV-specific humoral and cellular immune responses. The memory cell responses that develop during varicella or after vaccination contribute to protection following re-exposure to VZV. These responses are subsequently boosted either by endogenous re-exposure (silent reactivation of latent virus) or exogenous re-exposure (environmental). VZV-specific T cell-mediated immunity is also necessary to maintain latent VZV in a subclinical state in sensory ganglia. When these responses decline, as occurs with aging or iatrogenic immune suppression, reactivation of VZV leads to herpes zoster. Similarly, the magnitude of these responses early after the onset of herpes zoster correlates with the extent of zoster-associated pain. These essential immune responses are boosted by the VZV vaccine developed to prevent herpes zoster. PMID: 20473790 [PubMed - as supplied by publisher] 18.

Effective treatments and prophylaxis exist for the neurotropic herpes viruses HSV-1, HSV-2, varicella zoster virus, and possibly HHV-6. Antivirals seem to be less effective at prevention of the tumor-promoting effects of Epstein-Barr virus and HHV-8. Reduction in immunosuppression is the cornerstone to treatment of many diseases associated with herpes virus infections. Copyright (c) 2010 Elsevier Inc. All rights reserved.
