A case report of intracranial hypertension and aseptic meningitis: anti-tumor necrosis factor associated or juvenile idiopathic arthritis related.

BACKGROUND: The adverse effects of tumor necrosis factor alpha inhibitors (TNFi) are well characterized but rare adverse events are increasing day by day. CASE: We presented an 18-year-old girl with rheumatoid factor positive polyarticular juvenile idiopathic arthritis (JIA) who developed fever, headache, and nausea after the second dose of adalimumab. In addition to her suspicious complaints for meningitis, she had bilateral papilledema and partial abducens nerve palsy. Leptomeningeal contrast enhancement was noted in magnetic resonance imaging (MRI) of the brain. Brain MRI venography was normal. The cerebrospinal fluid (CSF) opening pressure was high but CSF analysis was normal. She was diagnosed with non-infectious subacute meningitis. Since brain biopsy was not performed, no definite distinction could be made between TNFi related aseptic meningitis or cerebral involvement of JIA. Due to the onset of neurological complaints after initiation of adalimumab treatment and rare cerebral involvement in JIA, the drug-associated aseptic meningitis was likely to be responsible in our patient. Adalimumab was discontinued and methylprednisolone followed by methotrexate treatment were initiated. Her symptoms resolved and control brain MRI was normal. CONCLUSION: Pediatric rheumatologists should be aware of this potentially severe side effect of anti-TNF treatment.

Neuroinvasive Listeriosis: Could Petechial Hemorrhages be a Diagnostic Clue?

INTRODUCTION: Listeria monocytogenes-related central nervous system infections may involve the cerebral parenchyma. Meningitis and meningoencephalitis are the most commonly seen forms and mainly affect immunocompromised patients; however, a less frequent form, rhombencephalitis, can occur in otherwise healthy people. Early treatment with appropriate antibiotic therapy is crucial for this otherwise fatal disorder. However, it is not always possible to rapidly establish the diagnosis because of varying presentations and discrepancies in diagnostic tests. CASE REPORT: Herein we report 3 cases of listerial infections involving the central nervous system parenchyma, with versatile diagnostic challenges and related possible solutions and radiologic hints to overcome similar issues in the future. CONCLUSIONS: We point out the importance of nonconventional magnetic resonance imaging techniques in the diagnosis, as we detected petechial hemorrhages in the brain parenchyma in all cases, which can be a diagnostic clue.

[Postherpetic neuralgia]. / Zona hastaligi ve zona sonrasi kalici agri (post-herpetik nevralji).

Following chicken pox infection, varicella-zoster virus stays as a latent infection in sensory root ganglia. After many years, the reactivation of this latent virus in sensory ganglia causes "herpes zoster". Herpes zoster (shingles) is an unilateral, dermatomal, localised, painful, vesicular, and contagious skin infection. In elderly and immunocompromised patients, shingles can cause complications such as postherpetic neuralgia (PHN) and direct central nervous system invasion. Early intervention with antiviral treatment, analgesic therapy and antidepressant therapy may reduce the risk of these complications. The treatment of PHN is same as for other neuropathic pain syndromes. The clinical importance of PHN is due to the severity and chronicity of pain which is usually not responsive to many treatments, and quality of life may be adversely affected by PHN.

Is the cell death in mesial temporal sclerosis apoptotic?

PURPOSE: Mesial temporal sclerosis (MTS) is characterized by neuronal loss in the hippocampus. Studies on experimental models and patients with intractable epilepsy suggest that apoptosis may be involved in neuronal death induced by recurrent seizures. METHODS: We searched evidence for apoptotic cell death in temporal lobes resected from drug-resistant epilepsy patients with MTS by using the terminal deoxynucleotidyl transferase (TdT) and digoxigenin-11-dUTP (TUNEL) method and immunohistochemistry for Bcl-2, Bax, and caspase-cleaved actin fragment, fractin. The temporal lobe specimens were obtained from 15 patients (six women and nine men; mean age, 29 +/- 8 years). RESULTS: Unlike that in normal adult brain, we observed Bcl-2 immunoreactivity in some of the remaining neurons dispersed throughout the hippocampus proper as well as in most of the reactive astroglia. Bax immunopositivity was increased in almost all neurons. Fractin immunostaining, an indicator of caspase activity, was detected in approximately 10% of these neurons. Despite increased Bax expression and activation of caspases, we could not find evidence for DNA fragmentation by TUNEL staining. We also could not detect typical apoptotic changes in nuclear morphology by Hoechst-33258 or hematoxylin counterstaining. CONCLUSIONS: These data suggest that either apoptosis is not involved in cell loss in MTS, or a very slow rate of cell demise may have precluded detecting TUNEL-positive neurons dying through apoptosis. Increased Bax expression and activation of caspases support the latter possibility.
