HSV-1: Gingivostomatitis is the major clinical presentation but HSV-1 also causes 15% of primary genital herpes cases.
Classical appearance of genital lesions is painful vesicles and ulcers in various stages of progression. Viral culture is the gold standard for diagnosis; most positive cultures are identifiable in 48 to 72 hours. Positive culture more likely in early vesicle lesions than later ulcerative crusted lesions. The monoclonal antibody test with type-specific assays for HSV- specific glycoprotein G1 or G2 can also be used.
Treatment instituted during prodrome or first 2 day9 of onset of lesions may provide limited benefit from therapy.
Should consider discontinuation of therapy to reevaluate frequency of recurrences after 1 year of suppressive therapy. Patients can be treated with intravenous therapy if indicated for complications of HSV such as encephalitis, pneumonitis, disseminated infection, or hepatitis. There is diffusion restriction on the DWI sequence involving the insular cortex and medial temporal region, with sparing of the basal ganglia, as mentionned previously. Sir,Japanese encephalitis is a central nervous system (CNS) infection caused by flavi virus, and it has high endemicity in southern parts of India. Herpes simplex virus 1 capsid: A T=16 icosahedral structure composed of the major capsid protein arranged in hexons (blue) and pentons (darker blue), and two minor capsid proteins forming triplexes (green). When you express interest in a specific study, the information from your profile will be sent to the doctor conducting that study. If you select a health category rather than a specific study, doctors who have active studies in that area may contact you to ask if you would like to participate. In both cases, you will be contacted by the preferred method (email or phone) that you specified in your profile. Infection within the CNS can result in meningitis, encephalitis or the formation of abscesses and empyemas.
Meningitis is the term used to describe inflammation of the meninges, irrespective of the cause. Classically, patients experience fever, headache, photophobia, vomiting and neck stiffness. A detailed history taken from the patient or informant will identify clues as to the aetiology of the infection, such as an unusual travel history, animal encounters and insect bites, intravenous drug use, chronic alcohol misuse, immunosuppression or head and neck trauma. Blood cultures, a platelet count and assessment of coagulation should be performed as soon as possible in all patients. Peripheral blood cultures, skin rash aspirates and posterior pharyngeal swabs can confirm meningococcal disease.
Three important and common pathogens are Neisseria meningitidis (meningococcus), Streptococcus pneumoniae (serotypes 6, 9, 14, 18 and 23) and, particularly in those <5 years, Haemophilus influenzae. Viral meningitis is generally a benign and self-limiting condition that requires no treatment other than symptomatic. Chronic alcoholics, the immunosuppressed and travellers from endemic areas are at risk of tuberculous meningitis.
Particularly with the increase in foreign travel, of which a careful history should be taken, the possibility of non-endemic infections should be considered. An inflammatory reaction in the subarachnoid space can be caused by mechanisms other than infection. The release of bacterial cell-wall products into the CSF, in part as a consequence of antimicrobial treatment, results in inflammation.


Encephalitis occurs when there is an inflammatory reaction in the brain parenchyma, either as the primary site of infection (such as in herpes simplex virus (HSV) encephalitis), or secondary to subarachnoid space infection (meningoencephalitis). Members of the arbovirus and enterovirus family also cause encephalitis – treatment is supportive only. The main differentials in the setting of encephalitis are the myriad causes of encephalopathy (disturbance of brain function) due to non-CNS diseases such as systemic infections (e.g. The drug interferes selectively with viral thymidine kinase and ultimately inhibits viral DNA synthesis. An evaluation of the usefulness of neuroimaging for the diagnosis of Japanese encephalitis. If bacterial meningitis is suspected, treatment with high-dose broad-spectrum antibiotics should be initiated without delay. Symptoms of systemic illnesses may lead to the source of infection, or identify a systemic illness associated with aseptic meningitis.
In adults, if there is no haemostatic defect, and a CT scan ofthe head is normal, then a lumbar puncture to confirm the presence and identity of the pathogen is the mainstay of diagnosis.
It commonly emerges in the setting of septicaemia and is most common in the under-12s with a prodrome of a throat infection. Rickettsial meningitis, for example, can be contracted worldwide via tick and mite bites, and the symptoms may only emerge when the traveller returns home. Listeria meningitis may be associated with late development of a rhombencephalitis, which involves the brainstem. Autoimmune diseases such as Behcet’s disease and sar-coidosis can cause aseptic meningitis.
Presentations range from mild with headache and confusion to more severe with seizures, focal neurological deficits, raised ICP and coma.
Infection of the CNS with varicella-zoster virus (VZV) is normally benign and self-limiting; however in immunocompromised patients, a post-infectious encephalomyelitis occurs, which may be treated with acyclovir. Corresponding hypersignal on FLAIR and hyposignal on T1.Although more frequently bilateral and symmetric, this cases demonstrates acute ischemia involving the right insular and temporal lobes, with sparing of the ipsilateral basal ganglia, compatible with herpes simplex encephalitis.
Thalamic hyperintensity in magnetic resonance imaging (MRI) is a specific finding which could be very useful in diagnosing Japanese encephalitis in the absence of serology. Infection or inflammation can spread beyond the meninges to cause cerebral dysfunction, drowsiness, delirium and coma. A history of neuroleptic use should raise the possibility of neuroleptic malignant syndrome as a non-infective cause of fever, neck stiffness and coma. Infection often localizes to the basal meninges resulting in cranial nerve palsies and spasticity. Rickettsial infections include Rocky Mountain spotted fever (seen in the Americas), typhus and Q fever (ubiquitous). Neoplastic disease can also cause aseptic meningitis; haematological malignancies such as lymphoma and leukaemia are most commonly involved, although leptomeningeal carcinomatosis can also occur as a consequence of metastatic spread from tum ours such as breast, lung and melanoma.
In adults, dexamethasone 10 mg should be given on suspicion of bacterial meningitis, with or just before the first dose of antibiotics. Treatment is supportive, with the exception of HSV for which intravenous acyclovir should be given without delay. Another important worldwide cause of encephalitis is rabies, which carries a 100% mortality rate. Cerebral abscess, (a) Axial contrast-enhanced Tl-weighted image in a 37-year-old woman shows a ring enhancing lesion in the left occipitotemporal white matter with low-signal intensity surrounding vasogenic oedema. We report a case with typical MRI finding and negative serology and discuss the differential diagnosis of bilateral thalamic hyperintensities in MRI.We admitted a 15-year-old previously healthy boy with high-grade fever and headache for three days.


Bacterial meningitis, particularly meningococcal disease, can kill within 12 h of symptom onset if left untreated. Its course is frequently complicated by shock and disseminated intravascular coagulation (DIC). All these infections present with high fever, skin rash and headache along with meningoencephalitis. Finally, a number of drugs can trigger aseptic meningitis, including non-steroidal antiinflammatory drugs (NSAIDs), intravenous immunoglobulins, azathioprine, carbamazepine, penicillin and isoniazid. It should then be continued, if the diagnosis is confirmed, at a dose of 10 mg every 6 h for 4 days.
In HSV infection, the diagnosis may be suspected based on imaging demonstrating changes in the temporal lobes (Fig. Axial fluid attenuation inversion recovery (FLAIR) image of a 73-year-old man showing increased signal intensity and swelling in the anterior and medial right temporal lobe. Commonly, complications such as cortical vein or sinus thrombosis, subdural empyemas, abscess formation or the development of hydrocephalus are responsible. Lumbar puncture is contraindicated in the setting of raised intracranial pressure (ICP), coagulopathy or thrombocytopaenia (particular care needed with meningococcal disease) or severe shock. 28.1), and EEG demonstrating periodic epileptiform activity lateralized to the site of infection.
Along with headache and fever, patients develop paraesthesias and pain at the inoculation site. In the vast majority of cases, but always in the setting of reduced consciousness and focal neurological signs, imaging (usually with CT) should be performed prior to lumbar puncture.
Treatment should be guided by local sensitivities, and accompanied by high-dose steroids for the first 4 weeks. On clinical examination, his mentation was normal, and there was no motor or sensory deficit, no neck stiffness and no nystagmus. His peripheral smear and quantitative buffy coat (QBC) were negative for Plasmodium falciparum infection.
He was investigated for a possible CNS infection.His cerebrospinal fluid (CSF) analysis done on the second day of admission showed mild lymphocytic pleocytosis with elevated protein.
MRI studies showed bilateral thalamic hyperintensity in T2-weighted Fluid-attenuated inversion-recovery imaging ( FLAIR) [Figure 1]a,b.
Results of polymerase chain reaction (PCR) tests done in CSF for herpes simplex encephalitis and tuberculosis were negative.
On day 7, he progressively developed acute respiratory distress syndrome (ARDS) and was put on ventilatory support. Japanese encephalitis, West Nile and Murray virus [2] are the three viruses causing encephalitis in the group of flaviviridae. Wernicke's encephalopathy, Wilson's disease, cerebral venous sinus thrombosis, slow virus disease (Creutzfeldt-Jacobs), gliomas and Fabry's disease are the other diseases that can present with similar MRI findings.In this clinical scenario, in line with the endemicity of the disease, there was a high likelihood that this was a case of Japanese encephalitis.
It has a peculiar biphasic pattern; however, there are only few reports available for the same. IgM antibodies can be detected usually on the eighth day, in some cases as early as the fourth. In endemic regions with appropriate history, even in the absence of serological evidence the most important clinical diagnosis of bilateral thalamic hyperintensities is viral encephalitis, possibly Japanese encephalitis.
