Three men who had worked at the same animal research facility and had had contact with macaque monkeys were infected with B virus (Herpesvirus simiae). Their clinical presentations varied from self-limited aseptic meningitis syndrome to fulminant encephalomyelitis and death. Patient 1 was treated only after a respiratory arrest and other signs of advanced brain stem dysfunction had occurred. He died 8 days after hospital admission, despite treatment with acyclovir. Patient 2 presented with subtle signs and symptoms of brain stem encephalitis. He received antiviral therapy with intravenous ganciclovir. Patient 3 had a headache without meningismus and was also treated with acyclovir. Both patients 2 and 3 survived and did not have objective sequelae. Viral culturing, ELISA and western blot antibody testing, and magnetic resonance imaging all proved useful in the diagnosis of these patients' conditions.

We report the case of a 57-year-old man with Listeria rhombencephalitis. This had been ascertained by means of Listeria isolation from the cerebrospinal fluid. After an nonspecific prodromial period with nausea and headache, he developed fever, meningism, brain stem dysfunction and an organic psychosis. With early antibiotic therapy (ampicillin/gentamycin), it was possible to bring about a restitio ad integrum. Different brain-imaging methods (computed tomography, MRI, brain SPECT) in the acute and follow-up stages are discussed.

The diagnosis and treatment of acute meningitis is a challenge for the primary care physician. Differentiating between bacterial meningitis and aseptic meningitis is not always straightforward. The aseptic meningitis syndrome is usually viral in origin, and enteroviruses account for most cases. The aseptic syndrome also may be caused by unusual bacterial organisms such as Mycobacterium tuberculosis, Leptospira species, Brucella species, Borrelia burgdorferi and others. The classic presentation consists of the acute onset of meningismus, headache, fever, malaise with pleocytosis and normal glucose and slightly elevated protein in the cerebrospinal fluid. Cerebrospinal fluid lactate and serum C-reactive protein measurements may be helpful in differentiating aseptic meningitis from treatable bacterial meningitis. Aseptic meningitis of viral origin usually responds to expectant care. Other causes of aseptic meningitis must be searched for and treated if present.

Varicella is an infrequent but potentially severe infection in adult HIV-infected patients. We reviewed five cases of varicella in HIV-seropositive men; two were complicated by severe headache and meningismus, and one of these patients also had hepatitis and thrombocytopenia. All five patients responded well to acyclovir therapy, but one patient had dermatomal zoster 2 years later, and another failed to have detectable antibody after infection. We also performed a serosurvey on 181 consecutive HIV-infected patients presenting themselves for evaluation. A total of 95% of these patients had demonstrable antibody to varicella-zoster virus. Immune status to varicella did not correlate with the declining CD4 count, which was well preserved even in patients with fewer than 200 CD4 cells/mm3.

The headache to worry about is one that is unique or different from headaches which the patient has suffered in the past. The association with the headache of meningismus or of focal neurologic symptoms of oculoparesis, other cranial nerve palsies, hemiparesis, or loss of consciousness are particularly worrisome, especially if onset is recent and acute. Headaches related to arteritis or vasculitis usually have a slower subacute course but may also produce focal neurologic deficits. For subjects over 50 years old, temporal arteritis is always a consideration and any new type of headache requires testing of the sedimentation rate to rule out this treatable but potentially devastating problem.

Listeria monocytogenes rhombencephalitis has never been studied in a significant group of patients. We describe 14 adult cases who were seen over a 10-year period. A biphasic illness was characteristic: (1) prodromes (5-15 days) with malaise, fatigue, headache, nausea or vomiting, and fever; (2) cranial nerve palsy with facial palsy, diplopia, dysphagia, dysarthria, usually multiple. Meningism and hemi- or tetraparesis were present in 11 patients and cerebellar dysfunction in 9 patients. In 4 cases, CT showed widening of the brain stem with disappearance of the surrounding cisterns. The cerebrospinal fluid was abnormal in all patients in whom this investigation was done (pleocytosis, elevation in protein content). The patients received antibiotic therapy for 2-6 weeks. In the 9 patients who recovered, the neurological dysfunction improved within 2 days to 1 week of the initiation of therapy. There were 5 deaths. At autopsy in 2 cases, there was severe purulent meningitis and rhombencephalitis with predominantly polymorphonuclear cellular infiltration in 1 case, while numerous microabscesses in the midbrain, pons and medulla were observed in the other. We conclude that L. monocytogenes infection should be considered in patients who develop fever and focal neurological signs particularly localized to the brain stem.

We present our experience with 10 liver transplant recipients in whom cryptococcal meningitis developed after liver transplantation. Disease developed a median period of 3.5 months (range, 2-36 months) after transplantation and patients were diagnosed a median period of 9 days (range, 2-90 days) after initial symptoms. Headache, fever, and mental status changes were the most frequent clinical presentations, while meningismus was found in only 30% of patients. Cerebrospinal fluid analysis was diagnostic in all cases. All patients were treated with amphotericin B and flucytosine. Immunosuppression was either decreased or discontinued during therapy. Five patients died, four as a direct result of cryptococcal infection and one as a result of chronic rejection. Three patients had long-term survival without any sequelae. One long-term survivor suffered blindness consequent to the disease. We conclude that cryptococcal meningitis is a rare complication in liver transplant recipients (0.25%), and has a high mortality rate (50%). Early recognition, combination antifungal therapy, and decrease or discontinuation of immunosuppression are important for cure. No relapse has been seen in surviving patients.

Bacillary dysentery, an acute infection caused by various strains of Shigella, is characterized by abdominal pain, tenesmus, and diarrhea with mucus, pus and blood. Neurologic manifestations including meningismus, delirium and convulsions may accompany the infection. We describe a thirteen-year-old girl who presented with headache, convulsion and loss of consciousness at the onset and developed diarrhea with blood and pus after hospitalization. The diagnosis of shigellosis was based on clinical data and isolation of the microorganism in the stool specimen. After improved physical functions, the patient developed mutism that continued for two days in the course of her illness, despite having no history of neurologic or psychological problems. She was diagnosed by a psychiatrist with organic mental syndrome NOS (Not Otherwise Specified) according to DSM-III-R criteria. None of the conditions that may cause mutism could be confirmed. This is the first reported case of mutism accompanying shigellosis.

We present 2 cases of Listeria monocytogenes rhombencephalitis (L-RE), both affecting previously healthy adult men. Each of them developed a diphasic syndrome first characterized by fever, nausea and headache, followed, in a second phase, by severe brain stem dysfunction at the level of the pons, with meningism, multiple cranial nerve palsies, ataxia, and, in one case, seizures. The early examination of the cerebrospinal fluid (CSF) demonstrated the presence of Gram-positive bacilli whose typical characteristics were compatible with those of Listeria, allowing for immediate administration of a specific therapy. Neuroimaging techniques (either CT or MRI) did not provide any evidence of brain stem involvement, and they did not positively contribute to the diagnostic process. The immediate use of a specific antibiotic therapy led to a favourable clinical outcome for both patients.

Eleven cases of cryptococcal meningitis were diagnosed and biotyped from September 1991 to August 1992 in Papua New Guinea (PNG). Seven isolates were Cryptococcus neoformans var. gattii from paediatric and adult patients, one with diabetes mellitus and 4 were C. neoformans var. neoformans from adults, of whom 2 had human immunodeficiency virus type 1 (HIV-1) infection, and one each had tuberculosis and Plasmodium vivax malaria. Significant clinical findings were headache, fever, meningism, vomiting, photophobia, papilloedema and cranial nerve lesions. Five patients (45.5%) died; 3 of these were adults with var. gattii and 2 were men with both var. neoformans and HIV-1 infections. This prospective tropical study documents the emergence of C. neoformans var. neoformans in patients with HIV-1 infection in a country where previously var. gattii had predominated in the immunocompetent. There has been no earlier report of cryptococcosis in an HIV-1 seropositive patient in PNG. Despite presumed exposure to both varieties of C. neoformans, var. gattii infections had been most frequent. As HIV-1 spreads, the proportion of hosts infected with var. neoformans may rise. The course of meningitis caused by the 2 varieties of C. neoformans may differ, with mortality in the tropics remaining particularly high. In PNG the environmental source of C. neoformans remains elusive.
