The clinical course and response to therapy of seven patients with cryptococcosis and AIDS were reviewed. One patient was still in the primary stage of cryptococcosis in AIDS, i.e. the stage that is characterized by the sole cultural detection of Cryptococcus neoformans in the respiratory tract. The other six patients were in the secondary stage, where C. neoformans can be detected from the cerebrospinal fluid (CSF), blood, urine, faeces and other body sites. The main presenting features (headache, fever, nausea) were due to central nervous system involvement, although meningism and mental changes were rarely present, and CSF changes were very subtle. Treatment with amphotericin B and flucytosine was very effective, there being no more growth of fungi in cultures in most cases. Adverse reactions to the drugs used occurred frequently and consisted mainly of anaemia, hepatosis and fever. Diagnosis in the primary stage of cryptococcosis may improve the prognosis.

One of the major side effects induced by the in vivo administration of the murine monoclonal antibody OKT3 is a spontaneously reversible clinical syndrome associating in variable proportions depending on the patient: fever, chills, headaches, diarrhea and seldomly meningismus. Sera from 3 renal allograft recipients treated with OKT3 were studied and showed that a massive although transient release of some cytokines namely, Tumor Necrosis Factor alpha, Interleukin 2 and Interferon gamma is observed following the first OKT3 injection.

A retrospective clinical and pathological analysis has been performed of 24 cases of herpes simplex virus encephalitis (HSE) seen at the Institute of Neurological Sciences, Glasgow, between 1972 and 1985. All patients had been diagnosed on the basis of isolation of herpes simplex virus (HSV) from, and/or the demonstration of characteristic histological changes of acute necrotizing encephalitis (ANE) in brain biopsy and/or autopsy tissue. Clinical presentation on admission included a prodromal influenza-like illness (46%), sudden onset of headache and confusion (54%), meningism (38%), deep coma (42%), aphasia (54%) and focal neurological signs (79%). Seizures occurred in 46% of cases during the course of the illness. Of the 24 cases, 14 (58%) died and 10 (42%) survived. Intravenous acyclovir treatment was associated with the best prognosis. Cerebral biopsy of one temporal lobe was performed in 22 cases and in 19 of these a positive histological diagnosis of HSE could be made. HSV was isolated from 15 of the 19 (79%) biopsied cases in whom virus isolation was attempted. Only seven out of the 15 cases (47%) in which immunofluorescence assays for HSV antigens were performed were unequivocally positive. Herpes simplex virus was isolated in culture from all cases which were negative by immunofluorescence. Immunocytochemical analysis on tissue sections of five representative brain biopsies demonstrated the presence of HSV antigens in some astrocytes, neurons and macrophages especially within areas of inflammatory infiltration. In situ hybridization experiments with a cloned HSV DNA probe demonstrated viral RNA in astrocytes, neurons and macrophages in two human biopsies and mouse brains in areas broadly corresponding to the distribution of viral antigen labelling. The combined immunocytochemical and in situ hybridization procedure showed that many but not all of the cells containing viral RNA also contained HSV antigens, indicating a productive infection in these double-labelled cells.

The clinical features, investigative profiles and outcome of 46 patients with biopsy or autopsy-proven herpes simplex encephalitis admitted to the Institute of Neurological Sciences, Glasgow between 1962 and 1985 were analysed retrospectively. The protean presenting symptoms and signs included a history of a prodromal influenza-like illness (48 per cent), rapid onset of headache, clouding of consciousness and confusion (52 per cent), meningism (65 per cent), raised intracranial pressure (33 per cent), deep coma (35 per cent), mutism or aphasia (46 per cent), focal neurological signs (89 per cent), and seizures (61 per cent). When seizures occurred they were almost always focal. The electroencephalogram was the most useful diagnostic test being abnormal in all cases, the majority showing focal changes in one or other hemisphere. Of the neuroradiological procedures employed, computerized tomographic and isotope brain scanning most frequently demonstrated localizing abnormalities in one or both temporal and/or frontal lobes. Midline shift was seen in half the cases. The cerebrospinal fluid was abnormal in every case but was not diagnostic. Cerebral biopsy of one temporal lobe was performed in 40 cases and a positive diagnosis of acute necrotizing encephalitis was made in 37 of these. Herpes simplex virus was isolated from the brains of 29 of the 40 cases in which the procedure was attempted, but immunofluorescence assays for antigens to herpes simplex virus were only positive in 11 out of 25 cases. Serological assays showed a greater than four-fold rise in the anti-herpes simplex virus antibody titre in 13 out of 22 patients tested.(ABSTRACT TRUNCATED AT 250 WORDS)

Meningitis should be suspected in a patient who presents with fever, meningism, or severe headache. A careful physical examination should be performed of perimeningeal foci, with emphasis on the sinuses, ears, throat, neck, and lungs. A history of exposure to tuberculosis, viral disease, rodents, or suspicious dairy products or farm animals may give clues to the source of the meningitis. Immunosuppression through the use of corticosteroids or chemotherapy for such conditions as Hodgkin's disease, lymphoma, leukemia, malnutrition, or acquired immunodeficiency syndrome (AIDS) should also be noted and alert the clinician to the possible presence of an unusual pathogen. Meningitis associated with leukemia or most of the non-T-cell lymphomas is likely to be from a common bacterial agent (often Listeria), unless the patient is being treated with a steroid or is receiving other chemotherapy. Patients with Hodgkin's disease or AIDS or who have been treated with a steroid are more likely to have cryptococcal or tuberculous meningitis. Neonates and the very elderly may present with only irritability or lethargy and fever, without any of the other common symptoms. In neonates up to one week of age, group B streptococcal infection should be suspected. Gram-negative organisms should be suspected in elderly patients and those who have had neurosurgery. In patients with CSF shunts, infection with coagulase-negative Staphylococcus should be assumed and these patients are treated empirically until results of cultures are received. Several noninfectious conditions may mimic infectious meningitis, as may some unusual causes of infectious meningitis (eg, syphilis and schistosomiasis), which have not been discussed in this article.

Leptomeningeal gliomatosis is reported in three patients in whom the tumor involved the central nervous system diffusely. Clinically, these patients presented with varying combinations of both non-localizing and focal symptoms and neurologic signs. Most notable were meningismus, vomiting, headache, altered level of consciousness and papilledema. Laboratory findings included high CSF protein, high CSF pressure and hydrocephalus but no direct evidence of neoplasia. All three patients received surgical treatment for hydrocephalus. Brains were swollen on gross examination with leptomeningeal thickening resulting from diffuse infiltration of tumor cells in the leptomeninges. In two of the patients small parenchymal gliomas in the brain were probably the source of the meningeal tumor.

Twenty cases of cryptococcal CNS infection treated at the Alfred and Fairfield Infectious Diseases Hospitals from 1975 to 1985 were reviewed. A predisposing immunological deficit was present in 40% of the cases and nearly half had evidence of pulmonary involvement. Severe headache was an almost universal presenting feature but fever and meningismus were not. Measurement of CSF cryptococcal antigen and CSF culture were far more reliable diagnostic markers than Indian ink smears. Cerebral CT scanning identified abnormalities in nearly 30% of cases, including 2 with cystic lesions and 2 with mass lesions. Combination therapy with amphotericin B and 5-fluorocytosine was used as first line treatment. Ventricular shunts were required for 2 patients with hydrocephalus, and persistently raised intracranial pressure often required frequent lumbar punctures and corticosteroids for control. Mortality was 30% and correlated with the presence of impaired conscious state, hydrocephalus or other neurological deficit, underlying immunodeficiency and low CSF glucose levels.

In 1982, an epidemic of acute trichinosis occurred in Bitburg with 402 cases. The acute stage was observed and documented in 193 patients. The first signs of the disease appeared on average 17 days after eating trichina-containing meat. Muscle pain was reported by 85% of patients, lid and/or facial edema by 83%, gastrointestinal complaints by 62%, fever by 60%, flu-like symptoms by 56%, headache by 26%, eye complaints by 19%. Eosinophils were present in the blood of 92%. Trichinella antibodies were demonstrated in 98% of patients examined for them. Interstitial myositis was found in 90% of muscle biopsies (from 162 patients). Serious complications--thrombosis, myocarditis, pneumonia, hepatitis or meningism--occurred in 26 (13.5%) of the 193 patients. Even six months after onset of the disease 43% of patients were still not free of symptoms.

2 cases of spinal subarachnoid hemorrhage due to tumors of the cauda equina are reported. In both cases the existence of cephalic meningeal signs first suggested an intracranial pathology and diagnostic procedures were performed in this direction. Only when these examinations were negative was a lesion of the cauda equina suspected. The lesion was located by myelogram and was diagnosed, after surgical removal, as a schwannoma and an ependymoma. The syndrome of spinal subarachnoid hemorrhage involves spinal symptoms and signs resembling violent lumbar and radicular pain with a hemorrhagic cerebrospinal fluid, in association with symptoms of intracranial origin such as headache and meningism. Lumbar and radicular pain preceding the headaches, and an unaltered level of consciousness, point to the rare syndrome of spinal subarachnoid hemorrhage.

Some aspects of typhoid fever in 77 children are discussed. There were 48 boys and 29 girls and their ages ranged from 1 month to 12 years. The patients were treated with chloramphenicol 100 mg/kg/d during the first 2 weeks and with either amoxycillin (100 mg/kg/d) or ampicillin (200 mg/kg/d) during the third week. The average duration of fever was 5.2 days. There was 1 relapse and 1 child, a baby aged 1 month, died. The correct diagnosis was not suspected by the referring doctor in 38% of the patients. On admission the commonest complaints were fever, abdominal pain, diarrhoea, headache and vomiting. The commonest findings on examination were tenderness or distension of the abdomen, apathy or delirium, rhonchi or crepitations, liver enlargement and meningism. There was anaemia (Hb less than 10 g/dl) in 23% and lymphopenia (less than 1500/microliter) in 43% of the patients. The differential white blood cell count revealed 5% or more unsegmented neutrophils in 32% of the patients, while 25% had 10% or more band cells. Two patients (sisters) failed to respond after 15 and 16 days of therapy with chloramphenicol and ampicillin because of resistant Salmonella typhi and were successfully treated with co-trimoxazole. Practitioners caring for black patients should always be on the alert for typhoid fever; some patients may not respond to chloramphenicol or amoxicillin. During the acute phase milk feeds are best replaced by soya products because of abdominal distension or aggravation of diarrhoea by milk.
