1/26. Seven-week interval between acquisition of a meningococcus and the onset of invasive disease. A case report.Invasive meningococcal disease (IMD) is thought to occur within a few days of pharyngeal acquisition of neisseria meningitidis. During a longitudinal study of carriage and acquisition among 2453 first-year undergraduates we identified a male student from whom N. lactamica was isolated in October 1997 followed by N. meningitidis in December 1997. In mid-January 1998 this student suffered a mild episode of IMD (meningitis) during which N. meningitidis was isolated from his CSF. The meningococcus carried in December 1997 was phenotypically and genotypically indistinguishable from the invading organism, suggesting the possibility that the organism may have been carried for 7 weeks prior to the onset of invasive disease. Further studies are needed to assess more accurately the range of asymptomatic carriage prior to disease onset.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
2/26. lyme neuroborreliosis mimics stroke: a case report.lyme neuroborreliosis is diagnostically challenging because of its diverse manifestations. The well-documented neurologic spectrum includes lymphocytic meningitis, cranial neuropathy, and radiculoneuritis in the early disseminated stage; and peripheral neuropathy, chronic encephalomyelitis, and mild encephalopathy in the late persistent stage. This case report describes a 74-year-old man who developed progressive left hemiparesis and facial palsy. The patient was hospitalized to rule out a cerebral vascular accident. The diagnosis of Lyme borreliosis was established with serologic studies. The patient was treated with intravenous ceftriaxone and responded with rapid clinical and functional recovery. lyme neuroborreliosis presenting as hemiparesis has rarely been reported. Prompt diagnosis and treatment appear to facilitate symptomatic relief and prevent persistent neurologic deficits.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
3/26. Progressive liver calcifications in neonatal coxsackievirus infection.Coxsackievirus group B can cause a severe systemic disease in the perinatal period. Severe manifestations like meningitis, encephalitis, hepatitis, and myocarditis have been previously reported. A case of a twin neonate infected by coxsackievirus group B is described, who developed progressive extensive hepatic calcifications demonstrated by ultrasound and computed tomography with follow-up. Hepatic calcifications in coxsackievirus infection have not been previously reported.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
4/26. Apparent progression of acute glomerulonephritis to dense deposit disease.One week after the diagnosis of meningococcal meningitis, an 8-year-old boy presented with acute renal failure and hypocomplementemia. A renal biopsy showed "postinfectious glomerulonephritis" and acute tubular necrosis. hematuria, proteinuria, and low complement levels persisted, and 2 years later a follow-up renal biopsy revealed dense deposit disease. The apparent progression of postinfectious glomerulonephritis to dense deposit disease as observed in this patient has not been previously described.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
5/26. Combined therapy of corticosteroid and azathioprine in hypertrophic cranial pachymeningitis.Hypertrophic cranial pachymeningitis (HCP) is a rare inflammatory disease of unknown origin in which recurrence is frequently observed in spite of the initial response to steroid therapy. Three patients, 1 man and 2 women, aged 63, 66, and 67 years, with severe intractable headache were evaluated by brain MRI. All patients were initially given prednisolone (60 mg/day, oral) or dexamethasone (20 mg/day, i.v.), and followed by long-term (at least 1 year) azathioprine therapy. All patients were evaluated by follow-up laboratory tests and brain MRI study, and completed the 2-year follow-up period. Symptoms including headache were initially improved with corticosteroid therapy, but patients became steroid-dependent. azathioprine administration in these steroid-dependent patients permitted the complete cessation of corticosteroid and led to the clinical and radiological recovery. In conclusion, initial high-dose corticosteroid administration followed by long-term azathioprine therapy may be the ideal treatment of HCP at present.- - - - - - - - - - ranking = 81.503002392352keywords = pachymeningitis, meningitis (Clic here for more details about this article) |
6/26. Rapidly growing tumor-like brain lesion.listeria monocytogenes accounts for 8-11% of the cases of bacterial meningitis which is associated with high mortality in patients with serious underlying diseases or those receiving immunosuppressive treatment. brain abscess due to L. monocytogenes is a very rare occurrence. The case reported here concerns a 54-year-old female patient with a rapidly growing tumor-like brain lesion. L. monocytogenes type 4b could be cultured from blood and brain biopsy. Despite antimicrobial therapy with ampicillin and gentamicin, the patient died 11 days after admission to the hospital. The growing numbers of elderly and immunocompromised patients will increasingly confront physicians with patients with listeriosis. Delayed therapy in patients treated with corticosteroids may result in a fatal outcome.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
7/26. Frequent association with neurosurgical conditions in adult proteus mirabilis meningitis: report of five cases.adult Proteus (P.) mirabilis meningitis is relatively rare and has not been examined individually in the English-language literature. During a period of 15 years (January 1986-December 2000), four adult patients with P. mirabilis meningitis and one adult patient with mixed bacterial meningitis involving P. mirabilis were identified at Chang Gung Memorial Hospital, Kaohsiung. These five patients included one man and four women, aged from 19 to 74 years (mean age=55.4). P. mirabilis infection accounted for 1.7% (4/229) of cases of our culture-proven monomicrobial adult bacterial meningitis and was involved in 7.1% (1/14) of cases of our adult mixed bacterial meningitis during this period. Underlying debilitating conditions including diabetes mellitus and neurosurgical disorders were common in these five cases. adult P. mirabilis meningitis had an acute clinical course, with fever and consciousness-disturbance occurring as most prominent clinical manifestations in all patients. Other common manifestations included hydrocephalus, seizure, septic shock and wound infection. Hematogenous spread would appear to be the most likely mechanism. Multi-antibiotic resistant strains of P. mirabilis were not found in our patients. All strains were susceptible to third-generation cephalosporins, imipenem, aztreonam and ciprofloxacin. The results of treatment for adult P. mirabilis meningitis were not satisfactory, most of the patients surviving with severe neurological deficit.- - - - - - - - - - ranking = 11keywords = meningitis (Clic here for more details about this article) |
8/26. Aseptic meningitis and optic neuritis preceding varicella-zoster progressive outer retinal necrosis in a patient with AIDS.Varicella-Zoster Virus (VZV) is the second most common ocular pathogen in patients with hiv infection. VZV retinitis is estimated to occur in 0.6% of patients with hiv infection and may occur in one of two clinical syndromes. The first is the acute retinal necrosis syndrome, which also may be seen in immunocompetent hosts. The second clinical syndrome occurs in patients with CD4 cell counts typically < 50 x 10(6)/l and is termed progressive outer retinal necrosis. VZV retinitis has been reported to occur simultaneously with other VZV central nervous system manifestations such as encephalitis and myelitis in hiv-infected patients. In addition, VZV retrobulbar optic neuritis heralding VZV retinitis has recently been described in hiv-infected patients who had suffered a recent episode of dermatomal herpes zoster. Herein we report the case of an hiv-infected individual who presented with VZV meningitis and retrobulbar optic neuritis that preceded the onset of progressive outer retinal necrosis. We also review of the literature of seven additional reported cases of retrobulbar optic neuritis preceding the onset of VZV retinitis.- - - - - - - - - - ranking = 5keywords = meningitis (Clic here for more details about this article) |
9/26. A case of anthrax meningitis.Meningeal anthrax is a very rare complication of the cutaneous, respiratory and gastrointestinal form of anthrax infection. anthrax bacilli, most commonly enter the body via the skin, and the organism then disseminates to the central nervous system via the hematogenous or lymphatic routes leading to fatal bacterial meningitis, even with intensive antibacterial therapy.- - - - - - - - - - ranking = 5keywords = meningitis (Clic here for more details about this article) |
10/26. diplopia in a patient with carcinomatous meningitis: a case report and review of the literature.In a patient with a history of malignancy, an isolated neurologic sign or symptom may indicate metastasis to the central nervous system. To exclude this possibility, a lumbar puncture should still be performed after a nondiagnostic cranial computed tomography (CT) scan even in the absence of signs of infection. A case is presented of a 59 year-old man recently diagnosed with non-Hodgkin's lymphoma that presented to the Emergency Department (ED) with the sole complaint of diplopia. Examination was unremarkable except for a left abducens nerve palsy. Cranial CT scan was normal but initial cerebrospinal fluid results were suggestive of carcinomatous meningitis, and cytology results later confirmed this diagnosis. A review of diplopia and carcinomatous meningitis is presented, along with a suggested conservative diagnostic algorithm for cancer patients presenting with neurologic signs or symptoms.- - - - - - - - - - ranking = 6keywords = meningitis (Clic here for more details about this article) |
