The authors report a case of primary Ki-1 lymphoma of the brain. The patient was a 4 1/2-year-old black girl who presented with a 4- and 5-day history of headaches, nausea, vomiting, neck stiffness, and difficulty in walking. Computed tomography (CT) scan of the brain showed two discrete densities in the left occipital lobe and in the brain stem. Magnetic resonance imaging (MRI) showed multiple densities scattered over the brain surface and brain stem. Microscopically, the tumor was an anaplastic neoplasm that diffusely infiltrated brain parenchyma. The neoplastic cells were large with amphophilic cytoplasm, large nuclei with irregular nuclear contours and prominent nucleoli. A high mitotic rate including atypical mitotic figures was noted. Immunohistochemical stains showed diffuse strong positivity for CD30 and moderate focal staining for epithelial membrane antigen. Leukocyte common antigen, cytokeratin, neuron specific enolase, monocyte/macrophage and B- and T-marker stains were negative. The histology was characteristic for Ki-1 large cell lymphoma. Cytologic examination of cerebrospinal fluid (CSF) demonstrated similar neoplastic cells. This is one of the first reports of this variant in the pediatric population.

Seventy-seven episodes of pneumococcal meningitis in 69 patients were reviewed. Twelve (15.6%) episodes occurred in those over 60 years old, 14 (18.2%) in patients between 10 and 60 years, 22 (28.6%) in patients between 2 and 10 years and 29 (37.7%) in those under 2 years. Overall mortality was 13.0% (10/77) and age of > 60 years was significantly associated with mortality (P < 0.05). Twelve episodes resulted in disabilities, eight of which were in those under 2 years, and took the form of hearing impairment in nine. Many patients had predisposing conditions with aural pathology, malignancy and diabetes mellitus being commonest in those over 10 years of age and aural pathology, preceding viral infection, renal disease, sinusitis or recent lower respiratory tract infection commonest in those aged between 2 and 10 years. Three of five patients with recurrent meningitis had CSF leaks. The most common features at presentation were fits, irritability, diarrhoea, and bulging fontanelles in those under 6 months; vomiting, drowsiness and poor feeding in those between 6 months and 2 years; neck stiffness, vomiting and drowsiness in those between 2 and 10 years while neck stiffness, focal neurology, headache and vomiting were commonest in those over 10 years old. Fever was common in all age groups as were foci of infection outside the CSF, with chest infections being significantly associated with mortality (P < 0.05). Of the laboratory parameters measured, low platelets (< 100 x 10(9)/l and high blood urea (> 7 mmol/l) were associated with mortality (P < 0.05). Blood cultures grew Streptococcus pneumoniae in 79.7% patients. Seventy-four (96%) patients had CSF taken of which 81% had gram films which were positive and interpreted correctly as showing pneumococci. Pneumococci were grown in 87.8% CSF cultures and all were sensitive to penicillin but a single isolate was chloramphenicol resistant. Many different antimicrobial drugs were used but penicillin plus chloramphenicol was the most commonly employed after the results of CSF microscopy were known and penicillin alone after culture results were available. Penicillin mono-therapy was associated with a low mortality.

A 58-year-old man with diabetes had fever and chills 5 days after ingestion of raw seafood. Nausea, vomiting, watery diarrhea, bilateral calf pain, and neck stiffness subsequently developed. Generalized edema and ecchymotic patches with a vesiculobullous eruption appeared on the extremities. Four blood cultures were positive for Vibrio cholerae non-01. The patient was successfully treated with antibiotics. This is the first documented case of V. cholerae non-01 septicemia with cutaneous lesions and meningitis in Taiwan.

Listerial brainstem encephalitis is a rare disease. Only 62 cases have been reported previously; all were in adults, only 8% of whom were immunosuppressed. The disease has a characteristic biphasic course: a nonspecific prodrome of headache, nausea or vomiting, and fever lasting for several days is followed by progressive asymmetrical cranial-nerve palsies, cerebellar signs, hemiparesis or hypesthesia, and impairment of consciousness. Neck stiffness was initially present in only 55% of the cases described thus far. Studies of cerebrospinal fluid often revealed only mild abnormalities. Cultures of cerebrospinal fluid and blood were positive in 41% and 61% of cases, respectively. Respiratory failure occurred in 41% of cases. Initial computed tomography of the brain often gave normal results; magnetic resonance imaging better demonstrated brainstem abnormalities. Overall mortality was 51%. All untreated patients died. When treatment with ampicillin or penicillin was initiated early, the rate of survival was > 70%; however, neurological sequelae developed in 61% of survivors.

An outbreak of aseptic meningitis caused by echovirus type 9 occurred between March and October, 1990, in Kagoshima, Southern Japan. Clinical manifestations and laboratory data of 259 children with aseptic meningitis who were admitted to the outpatient clinic of pediatrics in the Kagoshima City Hospital were analyzed (other diseases caused by echovirus type 9 were not investigated). The patients' age ranged from 1 month to 15 years and the highest incidence was in 4-year-old children. The male:female ratio was 1.3:1. Frequencies of headache (69%), vomiting (64%), neck stiffness (36%) and rash (195%) were lower than those in the previous reports in the United States or in the Europe. Pleocytosis in the cerebrospinal fluid increased with increasing age in the younger children. A predominance of neutrophils in cerebrospinal fluid lasted for 3 days or more after onset in 16% of the patients. Seroepidemiologic study suggested that the accumulation of susceptible children < 5 years of age had predisposed to the epidemic.

Subdural empyema, a collection of pus in the space between the dura and arachnoid, is a rare type of intracranial infection. We report on 23 patients, aged 8 months to 70 years, with subdural empyema who were treated in our clinic between 1989 and 1994. The sources of subdural empyemas were meningitis in five patients, middle ear in five, trauma in four, paranasal sinus in three, complications of surgery and subdural tap in four, and unknown in two patients. The common presentations were headache, focal neurologic deficit, fever, vomiting, seizures, and neck stiffness. Diagnosis was achieved by computerized tomography and neurologic examinations in all cases. Treatment was effected by burr hole or small craniotomy with catheter drainage, and antibiotics were administered to all patients. The mortality rate was 8.7%; the remaining patients made a good recovery without sequelae. We therefore recommend burr hole with catheter drainage plus antibiotics as a method of treating subdural empyema.

Children aged 1-59 months admitted to Goroka Base Hospital with signs suggestive of meningitis were recruited to determine what proportion of such children have clinical or bacterial meningitis and to investigate the bacterial aetiology. A laboratory classification of definite, probable, possible, indeterminate and no meningitis was established. Thirty per cent of 697 children had a final clinical diagnosis of meningitis, 12% had culture-proven bacterial meningitis (case fatality rate 34%) and 10% had probable or possible meningitis. Inability to feed, vomiting, drowsiness, "staring eyes" and haemoglobin < 9 g/dl in addition to the classical signs of meningitis were associated with increased mortality. Isolates from cerebrospinal fluid were 62 pneumococci, 22 Haemophilus influenzae type b (Hib) and one Neisseria meningitidis. Including blood culture-proven and antigen-proven Hib disease, Hib and pneumococci accounted for 44% and 46% of bacterial meningitis, respectively, and 23% of pneumococci were intermediately resistant to penicillin. Inability to feed, bulging fontanelle, convulsions in young children, neck stiffness, fever and "staring eyes" were all independently associated with bacterial meningitis. Conjugate Hib vaccine must be given to infants as early as possible. Conjugate pneumococcal vaccines, maternal immunization with 23-valent vaccine and pneumococcal protein vaccines are under investigation for prevention of pneumococcal disease.

An outbreak of aseptic meningitis due to echovirus 30 occurred in the Wingecarribee Shire, NSW, during October to November 1994, with 30 cases fitting the clinical case definition. Cases were ascertained from attendees of the local hospital. Medical files were reviewed and a standard questionnaire administered. Viral cultures were performed on CSF, throat swabs and stool specimens. The clinical presentation and laboratory findings were typical of viral meningitis. Cases were aged 8 months to 51 years; 26 were admitted to hospital. Headache was present in 93%, photophobia in 86%, vomiting in 69%, fever in 72%, and neck stiffness in 62%. In spite of temporal clustering, the mode(s) of transmission in this outbreak remain speculative. Although the route of transmission was not established, general hygiene measures to stop transmission were implemented when a common water source was excluded on epidemiological grounds.

Human parvovirus B19 infection can cause erythema infectiosum (EI) and several other clinical presentations. Central nervous system (CNS) involvement is rare, and only a few reports of encephalitis and aseptic meningitis have been published. Here, we describe 2 cases of B19 infection in a family presenting different clinical features. A 30 year old female with a 7-day history of headache, malaise, myalgias, joint pains, and rash was seen. Physical examination revealed a maculopapular rash on the patient's body, and arthritis of the hands. She completely recovered in 1 week. Two days before, her 6 year old son had been admitted to a clinic with a 1-day history of fever, headache, abdominal pain and vomiting. On admission, he was alert, and physical examination revealed neck stiffness, Kerning and Brudzinski signs, and a petechial rash on his trunk and extremities. Cerebrospinal fluid analysis was normal. He completely recovered in 5 days. Acute and convalescent sera of both patients were positive for specific IgM antibody to B19. Human parvovirus B19 should be considered in the differential diagnosis of aseptic meningitis, particularly during outbreaks of erythema infectiosum. The disease may mimic meningococcemia and bacterial meningitis.

The authors present an unusual complication of a recurrent chiasmal/hypothalamic pilocytic astrocytoma. From his second year of life onwards, the patient was repeatedly operated on and also underwent external radiation therapy (54 Gy total dose) 1 month after the first subtotal tumor resection. Nine years after irradiation, the patient was referred to our center with a sudden onset of severe headache, vomiting and neck stiffness. Computed tomography, magnetic resonance imaging, and cerebral angiography demonstrated an intratumoral, intraventricular, and subarachnoidal hemorrhage from an anterior communicating artery aneurysm encased in the pilocytic astrocytoma. The aneurysm was clipped and the patient recovered nicely from the hemorrhage. Three years later, the patient suddenly died of cardiac failure. Autopsy disclosed vessel wall changes compatible with radiation-induced vasculopathy. In light of this finding, the importance of radiation therapy and intracranial neoplasms for aneurysm formation is discussed.
