1/586. adult-onset MELAS presenting as herpes encephalitis.

    OBJECTIVE: To report an unusual presentation of mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) manifested in late life with a clinical picture of herpes simplex encephalitis. DESIGN: Case report. SETTING: Clinical neurology department in a tertiary care hospital. CASE DESCRIPTION: A 55-year-old woman developed aphasia and delirium during ophthalmic herpes zoster infection treated with oral prednisone and ophthalmic steroids, which was followed by progressive cognitive decline without acute neurologic events for 5 years. At age 60, the patient presented with new onset of seizures, hemiparesis, and hemianopsia. Subsequently she developed cortical blindness, multiple traumatic soft tissue injuries from falls, acute psychosis, and severe dementia with periods of agitation. She died in a nursing home in March 1997, 6 years after initial presentation. RESULTS: magnetic resonance imaging scan of the brain showed hyperintensity on T2-weighted images involving temporal, parietal, and occipital lobes bilaterally as well as mild atrophy of brainstem and cerebellum. Single photon emission computed tomographic imaging showed hypoperfusion of temporal, parietal, and occipital lobes. Results of video electroencephalographic monitoring showed periodic lateralizing epileptiform discharges in temporal and occipital areas. The serum lactate level was normal in May 1996 and elevated in October 1996. The creatine kinase level was elevated with a 100% MM fraction in August 1991 and normal in March 1996. Results of repeated cerebrospinal fluid analyses indicated elevated protein levels. Analysis of dna was diagnostic of MELAS by mitochondrial dna point mutation at position 3243. The results of autopsy showed moderate cerebral, cerebellar, and brainstem atrophy with signs of infarction in temporal and parietal lobes bilaterally. CONCLUSIONS: The clinical presentation as well as age at onset of MELAS are highly variable. Onset of mitochondrial disorders can be provoked by febrile illness when there is mismatch between energy requirements and availability. In the differential diagnosis of herpes encephalitides, melas syndrome should be considered.

2/586. PCR-based diagnosis of a case of herpetic whitlow in an AIDS patient.

    Herpetic infections are common complications in AIDS patients. The clinical features could be uncommon and antiviral chemotherapy is imperative. A rapid diagnosis could prevent incorrect approaches and treatment. The polymerase chain reaction is a rapid, specific and sensible method for dna amplification and diagnosis of infectious diseases, especially viral diseases. This approach has some advantages compared with conventional diagnostic procedures. Recently we have reported a new PCR protocol to rapid diagnosis of herpetic infections with suppression of the dna extraction step. In this paper we present a case of herpetic whitlow with rapid diagnosis by HSV-1 specific polymerase chain reaction using the referred protocol.

3/586. Vascular changes in tuberculous meningoencephalitis.

    Our report refers two cases of tuberculous encephalomeningitis which differ in the course and pathological changes. In case 1 blood vessels showed features of peri, endo-, or panvasculites. In some vessels endothelium proliferation leading to the stenosis or obliteration of the vascular lumen was observed. necrosis was an effect of vessels occlusion. In case 2 many fewer vessel were involved in onflammation process. Vascular changes were also less extensive and were observed more rarely. Tuberculous infection often caused less tissue lesions than vascular changes. Different pathological changes probably depend on the type and virulence of Myobacterium tuberculosis and on the host immune response to the infection.

4/586. Chronic herpes simplex virus type I glossitis in an immunocompromised man.

    herpes simplex virus (HSV) type 1 (HSV-1) infection of the tongue commonly accompanies acute primary herpetic gingivostomatitis. However, recurrent infection of the tongue is exceptional and is restricted to immunocompromised individuals. A 57-year-old man with corticosteroid-dependent chronic obstructive pulmonary disease and sciatica presented with a chronic median glossitis due to HSV-1. The main clinical and histological feature was massive necrosis of the entire mucosa. immunohistochemistry demonstrated a considerable amount of HSV gB, gC and gD envelope glycoproteins dispersed in the chorion. In contrast, HSV-1 dna was detected only in a limited number of epithelial cells using in situ hybridization. The extent of necrosis and the pattern of viral dna and envelope protein distribution represent unique features of median herpetic glossitis, which are not found in more common types of HSV infection.

5/586. Fatal herpetic hepatitis in adult following short corticotherapy: a case report.

    herpes simplex virus hepatitis (HSV hepatitis) is an uncommon and severe complication of HSV type 1 and HSV type 2 infection. HSV hepatitis affects mostly immunocompromised patients. We report the case of a young man without any previous known immunodeficiency who developed fatal HSV hepatitis in the first 8 days of oral corticotherapy given for ulcerative colitis. A prompt diagnosis was possible because HSV was recovered from peripheral blood leukocytes.

6/586. Sequential peripartum herpes simplex virus type 2 disease in parents and their newborn mimicking intrafamily spread of common viruses.

    herpes simplex type 2 (HSV2) disease developed sequentially among two parents and their newborn. The father first became ill with upper-respiratory symptoms and fever. Then, 5 days later, shortly after delivery, the mother had fever, pharyngitis, and diarrhea. Subsequently, the infant developed undifferentiated febrile illness at the age of 3 days. HSV etiology was recognized by incidental isolation of HSV2 from the newborn naospharynx. The father never developed genital lesions and the mother's symptoms remained nonspecific for several days prior to the onset of genital manifestations. The sequential emergence and manifestations of these infections could have been misconstrued for an intrafamily spread of respiratory or enteric viruses. This cluster illustrates that HSV2 may cause sequential symptomatic disease in susceptible individuals mimicking other viruses.

7/586. Fulminant herpes hepatitis in a healthy adult: a treatable disorder?

    hepatitis due to herpes simplex virus (HSV) is a potentially fatal disorder that is often not considered in the differential diagnosis of acute hepatitis. This disease occurs most often in patients with impaired immunity and is very uncommon in healthy patients. HSV hepatitis presents with a wide clinical spectrum, and the clinical diagnosis is difficult. We describe a case of disseminated herpes virus infection with fulminant hepatitis mimicking an acute human immunodeficiency virus infection in a 33-year-old healthy man. Preliminary studies suggest that early treatment of HSV hepatitis with acyclovir may be beneficial in these patients. A high index of suspicion and the availability of early diagnostic tools, such as HSV dna detection, may dramatically improve the clinical outcome of severe HSV hepatitis.

8/586. Herpetic salpingitis and fallopian tube prolapse.

    AIM: We describe the unusual association of fallopian tubal prolapse and herpetic infection, an occurrence not previously reported to our knowledge. methods AND RESULTS: A 37-year-old woman presented with a small polypoid mass of the vaginal vault, 3 months after abdominal hysterectomy and abdominoplasty. The vaginal mass proved to be the fimbriated end of a fallopian tube, herniated into the vagina. Reintervention 3 months later with resection of a small vaginal 'polyp' revealed a residual portion of fallopian tube, with superimposed herpes simplex virus (HSV) infection and marked cytological atypia of surface epithelial cells. HSV-2 immunostaining of viral nuclear inclusions and of atypical cells confirmed the herpetic nature of the infection. CONCLUSION: Involvement of the genito-urinary tract by HSV may occur via an ascending infection from the cervix, but the fallopian tube, deeply located in the pelvis, is generally spared from herpetic infection. In the setting of fallopian tubal prolapse, direct exposure of the herniated fallopian tube to various pathogens in the vagina provides an unique clinical model for salpingitis. In herpetic tubal infections, special attention must be paid to cytological atypia of probable viral cytopathogenic origin, to avoid a misdiagnosis of malignancy.

9/586. Longitudinal study of a patient with herpes-simplex-virus-associated erythema multiforme: viral gene expression and T cell repertoire usage.

    BACKGROUND: erythema multiforme is a polymorphous self-limited, often recurrent eruption that can follow herpes simplex virus (HSV) infection, hereby designated HAEM. Studies of relatively large groups of patients during one recurrent episode indicated that HAEM pathogenesis is associated with HSV gene expression, Vbeta2 T cell infiltration of lesional skin and altered T cell receptor (TCR) repertoire usage by HSV-stimulated peripheral blood mononuclear cells (PBMC). However, HAEM recurrences are not always preceded by overt HSV eruptions and virus cannot be isolated from HAEM lesional skin. Therefore, it is unknown whether all HAEM recurrences experienced by a given patient are HSV related. OBJECTIVE: The studies described in this report were designed to examine whether all HAEM recurrences experienced by a given patient are HSV related. methods: We describe one patient who was studied longitudinally during 6 HAEM recurrences and in the intervening lesion-free periods. Lesional skin from all HAEM episodes was studied for HSV gene expression and infiltration by Vbeta2 and Vbeta3 T cells. PBMC obtained at these times were assayed for TCR repertoire usage upon HSV stimulation. RESULTS: Lesional skin from all HAEM episodes was positive for HSV gene expression (rna and protein) as well as Vbeta2 T cell infiltration. HSV-stimulated PBMC obtained at these times had an altered TCR repertoire characterized by a predominance of Vbeta2 cells. The duration of viral gene expression, Vbeta2 cell infiltration and altered TCR repertoire usage correlated with the duration of clinical symptoms. CONCLUSION: The data suggest that HSV and a virus-specific immunopathology component are involved in the causation of all HAEM episodes experienced by the patient.

10/586. herpes simplex encephalitis after brain surgery: case report and review of the literature.

    Intracranial infection after neurosurgical intervention most often is caused by bacteria. A rare case of fatal herpes simplex encephalitis after removal of a meningioma is described and similar cases reported in the literature are reviewed. Recent diagnostic tools, including detection of herpes viral dna sequences by polymerase chain reaction, complement clinical suspicion and facilitate mandatory early diagnosis, because herpes encephalitis, without rapid initiation of treatment, may lead to severe disability or death.
