Forty-three consecutive cases of acute aseptic meningitis (AAM) presenting within a 24-months period were retrospectively analysed with respect to clinical symptomatology, cerebrospinal fluid (CSF) findings, clinical course, treatment and outcome. Nineteen of the 43 AAM cases (44%) were caused by enterovirus, one by HIV (2%), two by Varicella zoster virus (5%), three due to herpes simplex virus I (7%), two due to herpes simplex virus II (5%), one due to Central European encephalitis virus (2%), and in 15 patients (35%) the aetiology of AAM remained unknown. Headache (100%) and fever (93%) were the presenting symptoms in the majority of cases. Signs of preceding infection were predominantly gastrointestinal in the enterovirus subgroup, but were inconsistently observed in the other subgroups. CSF findings at the first lumbar tap on admission generally revealed lymphomonocytic pleocytosis of less than 500 cells per micro l, mild to moderately elevated protein and normal lactate and glucose levels. Initial therapy consisted of an empirical antiviral and antibiotic regimen until a serological diagnosis was available. Acyclovir, effective only in herpes family viruses, was initially administered to all AAM cases. Effective therapy for other viral pathogens are not broadly available and treating AAM of unknown aetiology imposes a particular problem. The average hospitalization time ranged from 16 to 31 days. Patients were either discharged home (72%) or transferred to a rehabilitation centre (28%). The outcome was good (40%) to fair (51%) in the majority of cases.

Stevens-Johnson syndrome (SJS) is defined as a severe erythema-multiforme-like eruption of the skin and lesions of the oral, genital and anal mucosa and hemorrhagic crusting on the lips; it is associated with fever, headache, and arthralgia. The disease is a part of a continuum of immunologically mediated mucocutaneous diseases at various grades of severity. SJS is often induced by drugs, but the pathophysiologic mechanism is completely unknown. Patients and their first degree-relatives may have genetic defects in their metabolic pathways that lead to the accumulation of toxic metabolites. However, viral infections are known triggers of this skin disorder. Varicella zoster virus has been only very rarely reported as an etiological agent in SJS, despite its high incidence as a pathogen in childhood. In this study, we report a case of primary varicella infection associated with SJS because of its rare presentation. To the best of our knowledge, our case is the youngest child in the literature.

Varicella zoster virus causes two distinct clinical diseases. Varicella is the primary infection and results from exposure of a person susceptible to the virus. The virus remains latent in cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia along the entire neuraxis. Years later, in association with a decline in cell-mediated immunity in the elderly and immuno-compromised, varicella zoster virus reactivates and can cause a wide range of neurologic disease, including herpes zoster ('shingles'), postherpetic neuralgia, vasculopathy, myelopathy, retinal necrosis, cerebellitis, and zoster sine herpete. Herpes zoster is associated with numerous neurologic complications and varied presentations. Patients who have a dermatomal distribution of varicella zoster virus and who have headaches should be considered to have VZV meningitis. Virologic confirmation requires testing the cerebrospinal fluid for varicella zoster virus deoxyribonucleic acid via polymerase chain reaction. The application of polymerase chain reaction to the cerebrospinal fluid can be used to detect varicella zoster virus deoxyribonucleic acid and, therefore, infections of the central nervous system. We present a case report of a 46-year-old female who initially presented with worsening headache, nuchal rigidity, fever, and a skin rash, who was subsequently found to have varicella zoster meningitis.

Varicella zoster virus (VZV) belongs to the group of herpes viruses. It can cause a number of nervous system infections. We present 2 of 4 patients seen recently suffering from acute meningoencephalitis, in which VZV proved to be the infectious agent. The first patient was a 57-year-old woman with headache, vomiting, and sudden aggressiveness. The second patient was a 60-year-old man with headache, nausea, and vomiting. Neither patient had skin eruptions usually associated with VZV reactivation, nor had either recently suffered from herpes zoster. Both patients had in their cerebrospinal fluid a lymphocytic pleocytosis, a decreased glucose concentration and and an elevated protein concentration. The patients recovered within a few days of starting intravenous treatment with aciclovir 10 mg/kg 3 times daily for one week. Recent literature shows that VZV is a common pathogen in meningoencephalitis and is probably underestimated as a putative cause of this condition. VZV meningoencephalitis usually has a mild course, but serious complications have been reported. Patients present with headache and usually fever. Nuchal rigidity and meningeal irritation are not always present. Since the advent of the PCR technique, VZV has been readily demonstrable. Anti-viral treatment is advised despite the lack of placebo-controlled studies, and may be combined with prednisone.

Central nervous system involvement in a patient with primary infection with Varicella zoster virus is rare, especially in the immunocompetent adult. In particular, isolated optic neuritis has been described in a small number of cases. The authors present a case of optic neuritis in an immunocompetent patient. A 28-year-old woman presented to the emergency room with a history of headaches during the previous week, without visual symptoms. The examination was unremarkable, except for a rash suggestive of chickenpox and hyperemic and edematous optic disc, bilaterally. Visual acuity and neurological examination were normal. Two days later, she complained of pain on eye movement and decreased visual acuity, which was 20/32 in her right eye and 20/60 in her left eye. Four days after admission, her visual acuity started to improve, and two months later, she had 20/20 visual acuity in both eyes. To our knowledge, this is the first reported case of an immunocompetent adult in which a Varicella zoster virus associated optic neuritis presented with fundoscopic changes before decreased visual acuity. This suggests that this condition may be underdiagnosed in asymptomatic patients.

Varicella zoster virus (VZV) causes the primary infection manifesting as varicella or chickenpox, with possibility of reactivation later in life. A 71-year-old man presented with headache and lower extremity weakness. There was no evidence of skin lesions to suggest a recent zoster infection. The patient had a history of multiple myeloma diagnosed 2 years earlier, treated with chemotherapy and autologous stem cell transplant. Antimicrobial prophylaxis was discontinued 12 months after the transplant. MRI of the brain demonstrated areas of T2/fluid-attenuated inversion recovery hyperintensity in bilateral cerebral white matter and MRI of the spine demonstrated enhancement along the cauda equine. Cerebrospinal fluid (CSF) analysis showed lymphocytic pleocytosis and VZV DNA was detected by PCR in the CSF. The patient was treated with 8 weeks of antiviral therapy with complete resolution of symptoms. VZV should be considered in patients with haematopoietic stem cell transplantation presenting with similar neurological manifestations even in the absence of dermatological signs.

A 19-year-old girl with a history of precursor B acute lymphoblastic leukemia in remission presented with fever, headache, and a skin rash. Cerebrospinal fluid (CSF) examination reported pleocytosis with blast-like cells concerning for a central nervous system leukemic relapse. After the patient showed significant improvement on intravenous acyclovir, a repeat lumbar puncture revealed normalization of CSF. The abnormal CSF cells were reviewed and ultimately determined to be activated and atypical lymphocytes. The patient recovered uneventfully. Atypical lymphocytes resembling leukemic blasts are an unusual finding in viral meningitis. Varicella zoster virus reactivation should be considered during initial evaluation for central nervous system relapse of leukemia.

Objective To establish an epidemiological surveillance of viral herpes encephalitis in major hospitals of Monteria, Cordoba. Methods From September 2009 to December 2011, a descriptive study of cases of viral encephalitis was made in three hospitals in the city of Monteria. Cerebrospinal fluid (CSF) samples from 118 patients were included in the study. Clinical aspects, as well as cytochemical and microbiological analysis (Gram stain and culture) of CSF, were used for selecting the patients. Virus detection was performed by using multiplex nested PCR for Herpes simplex virus 1 and 2, Epstein Barr virus, Cytomegalovirus and Varicella zoster virus. Results Viral DNA of herpesvirus was detected in the CSFs of 30 (25.4 %) participants, as follows: 22 (18.6 %) Herpes simplex 1 and 2 viruses, 4 (3.3 %) Cytomegalovirus and 1 (0.8 %) Varicella zoster virus. Co-infections were observed in 3 patients (2.5 %), 1 case by HSV-VZV and 2 cases by CMV/HSV. The clinical manifestations of the patients included: headache (18.6 %), fever (14.4 %), asthenia (10.1 %), seizures (9.3 %), vomiting (8.4 %), and stiff neck (5.9 %). Thirty percent of the patients also had HIV-AIDS. A case fatality rate of 20 % was observed for the patients. Conclusions This paper shows that herpesvirus is a cause of infection of the CNS in patients from Cordoba. This study contributes to the epidemiology of encephalitis, as well as to patient management.

A 50-year-old woman was admitted to our hospital with dysesthesia on the right upper portion of her face and a headache. Diffusion-weighted brain magnetic resonance imaging (MRI) revealed high-intensity signals in the dorsolateral portion of the medulla oblongata. She was diagnosed with lateral medullary infarction and was intravenously treated with sodium ozagrel. On the second day of hospitalization, she had nausea and vomiting and showed nystagmus to all directions, suggesting damage to the vestibular nucleus. These manifestations coincided with partial symptoms of lateral medullary syndrome. On the third day of hospitalization, a rash appeared on the region of skin innervated by the first and second branches of the right trigeminal nerve. A reevaluation of the MRI findings indicated the presence of a lesion of the right spinal trigeminal nucleus and tract. She was treated with acyclovir for 14 days, and was discharged without any residual symptoms. Varicella zoster virus-DNA was detected in her cerebrospinal fluid. This disease mimics the presentation of a stroke and is important for differential diagnosis. (Received August 1, 2017; Accepted September 14, 2017; Published February 1, 2018).

Vernet syndrome is a unilateral palsy of glossopharyngeal, vagus, and accessory nerves. Varicella zoster virus (VZV) infection has rarely been described as a possible cause. A 76-year-old man presented with 1-week-long symptoms of dysphonia, dysphagia, and weakness of the right shoulder elevation, accompanied by a mild right temporal parietal headache with radiation to the ipsilateral ear. Physical examination showed signs compatible with a right XI, X, and XI cranial nerves involvement and also several vesicular lesions in the right ear's concha. He had a personal history of poliomyelitis and chickenpox. Laringoscopy demonstrated right vocal cord palsy. Brain MRI showed thickening and enhancement of right lower cranial nerves and an enhancing nodular lesion in the ipsilateral jugular foramen, in T1 weighted images with gadolinium. Cerebrospinal fluid (CSF) analysis disclosed a mild lymphocytic pleocytosis and absence of VZV-DNA by PCR analysis. Serum VZV IgM and IgG antibodies were positive. The patient had a noticeable clinical improvement after initiation of acyclovir and prednisolone therapy. The presentation of a VZV infection with isolated IX, X, and XI cranial nerves palsy is extremely rare. In our case, the diagnosis of Vernet syndrome as a result of VZV infection was made essentially from clinical findings and supported by analytical and imaging data.
