To investigate the clinical character of an outbreak of aseptic meningitis in Iwamizawa 1997 caused by echovirus 30, and to investigate the spreading of the outbreak, we analyzed clinical character of 75 hospitalized patients in our hospital, and mapped the patients' distribution in Iwamizawa City each week. We detected in our hospital an epidemic outbreak of acute enteroviral meningitis caused by echovirus type 30 in Iwamizawa, from September to December, 1997. Regarding the patients, there was little prevalence in males, with an average age of 6 years and a range of 0 to 13 years of age. The most constant symptoms were three major one such as headache (90%), fever up (89%), vomiting/nausea (87%), sometimes sorethroat (30%) and abdominal pain (15%). One case had a febrile convulsion temporally, and two cases had acute meningoencephalopathy and- encephalitis. In the cereblospinal fluid (CSF), we found no predominance of mononuclear cell (MNC) (58%) in the differential cell count. The mean of the peak of CSF cell counts was 654/3. White blood cell (WBC) was 8940/microliters, and CRP 1.4 mg/dl. None of them was detected in the bacterial culture of the CSF. Viral cultures were performed on CSF in 26 cases. Echovirus type 30 was isolated in 4 cases of hospitalized patients, and in one case with meningismus without pleocytosis. The beginning of the outbreak was observed in two kindergarten and one elementary school side by side. The peak of the whole outbreak was detected in the 3rd to 6th week, however the school spreading peak was detected in the 3rd and 4th week, and spreading was going in the whole city.

A 82-year-old female was admitted to hospital because of deteriorated general condition, severe diffuse headache and complete left-sided ptosis. A computed tomography scan of the head revealed no subarachnoid haemorrhage. Based on the hypothesis that the symptoms resulted from an infarction in the brain stem, the previous medication with Aspirin was continued. After repeated vomitus hypotensive dehydration developed and was adequately treated. Because of confusion, elevated white blood counts and signs of meningism, a spinal puncture was performed. Only the serology for Borrelia-IgG was positive, therefore the patient received Rocephin. During treatment only the ptosis persisted, therefore the substitution with sodium and the medication with Prednisone were stopped. Afterwards the symptoms reappeared and the laboratory results showed insufficiency of the pituitary. A magnetic resonance scan showed a microadenoma of the pituitary with local bleeding. Nine months after pituitary apoplexy, with hormonal substitution only a divergent strabism on the left side persisted. Clinical findings, course and therapy of pituitary apoplexy are discussed.

We report on a case of a lumbar epidural abscess with staphylococcus aureus following a catheter epidural anaesthesia in a previously healthy and not immunosuppressed 34-year-old female. The indication for the epidural anaesthesia was mobilization of the right knee following arthrotomy due to chronic synovitis. On postoperative day 7 the patient experienced lumbar pain, headache and meningism. Magnetic resonance imaging revealed an epidural abscess at the height of the 3rd and 4th lumbar vertebrae. A right-sided intralaminar fenestration with debridement and drainage of the abscess was carried out immediately after confirmation of the diagnosis. The patient was discharged from hospital on postoperative day 21 without any neurological sequelae. This is another addition to the published cases of epidural abscess following a epidural technique. It underlines the need for a proper aseptic technique, to abandon frequent changes of bacterial filters, daily examination of the entry site of the catheter and strategies for close and continuous monitoring of patients following epidural anaesthesia.

A 42-year-old house wife presented with worsening headaches over 6 months in the absence of visual symptoms or symptoms suggestive of focal neurology. She was a life-long smoker. Systems review was unremarkable apart from secondary amenorrhoea and galactorrhoea of 6 months duration. Her serum prolactin was found to be 620 mU/l (60-400), FT4 12.6 nmol/l (9.8-23.1), TSH 1.38 mU/l (0.35-5.5), oestradiol < 73 pmol/l, LH and FSH of 4.4 and 12.6 mIU/l, respectively. She was on bromocriptine. A presumptive diagnosis of pneumonia, based on pyrexia and CXR findings, was made and she was started on IV antibiotics. Two days later she developed meningism and deterioration of conscious level. (Lumbar puncture results: no organisms, 312 neutrophils and 164 lymphocytes). CT scan revealed a 2.5-cm pituitary adenoma, with suprasellar extension. A repeat hormonal profile revealed FSH 1.4, LH < 0.3 mU/l, oestradiol < 73 pmol/l, prolactin 488 mU/l (60-400), and low random cortisol at 29 nmol/l. T1-weighted MRI revealed a large pituitary mass with evidence of haemorrhage. The patient subsequently underwent a transsphenoidal exploration with resection of the pituitary lesion. Whilst awaiting the histopathology results, CT of chest revealed a 1. 5-cm diameter rounded well defined density in the right lower lobe associated with hilar, pre- and right para-tracheal lymphadenopathy. The histopathology of the pituitary lesion, obtained piecemeal, revealed fragments of fibrous tissue infiltrated by sheets of acidophilic prolactin-positive cells, in keeping with a prolactinoma. In addition, other fragments with blood clot included highly atypical epithelial cells with mitotic figures. These were negative for prolactin but showed HMFG-and CEA-positivity, excluding them from a pituitary lineage. Transbronchial biopsy revealed moderately differentiated adenocarcinoma, with evidence of lymphatic spread. The overall conclusion was of bronchogenic adenocarcinoma, metastasizing to a prolactinoma and complicated by apoplexy.

We report on a 35 year old female with a 26 day history of an intermittent cerebellar syndrome (dysarthria, ataxia of extremities, gait and trunk, nystagmus), mild meningism, cephalgia, recurrent emesis and nausea. Symptoms developed after typically chickenpox exanthema. Examination of the liquor showed mild pleocytosis, elevated protein and increased albumin quotient. Virus was not found by EIA or PCR. There were elevated levels of IgM- and IgG-antibodies to VZV. The EEG showed mild general changes, compatible with an encephalitis. Neuroradiological examinations were unremarkful. The neurological deficits partly regressed in the follow-up of two months. To the best of our knowledge we are the first that describe the paradox of an intermittent cerebellar syndrome after infection with chickenpox without detection of the virus in the liquor. This phenomenon can be related to the unusual combination of cerebellar ataxia and the later occurrence of mild encephalitis.

Meningitis is the most common serious manifestation of infection of the central nervous system. Inflammatory involvement of the subarachnoid space with meningeal irritation leads to the classical triad of headache, fever, and meningism, and to a pleocytosis of the cerebrospinal fluid (CSF). Meningitis is clinically categorized into an acute and chronic disease based on the acuity of symptoms. Acute meningitis develops over hours to days, while in chronic meningitis symptoms evolve over days or even weeks. Aseptic meningitis, in which no bacterial pathogen can be isolated by routine cultures, can mimic bacterial meningitis, but the disease has a much more favorable prognosis. Many cases of aseptic meningitis are caused by viruses, primarily enteroviruses, but bacteria and noninfectious etiologies also cause meningitis with negative cultures. Symptoms of meningeal inflammation with CSF pleocytosis that persist for more than 4 weeks define the chronic meningitis syndrome. The diagnosis is based on the patient history, clinical evidence of meningitis, CSF examination, and often imaging studies. The differential diagnosis is broad, and the predominant CSF cell type can provide clues as to the underlying disease. Empiric therapy is primarily based on the age of the patient, with modifications if there are positive findings on CSF gram stain or if the patient presents with special risk factors. In patients with chronic meningitis, a definite diagnosis is often not available or delayed for days, in which case empiric therapy may have to be initiated. It is important to cover the treatable causes of meningitis, for which the outcome is poor if treatment is delayed.

Neurological manifestations are frequent in patients with AIDS. Many neurological disorders have disappeared with the advent of highly active antiretroviral combination therapies. We can speculate that some of these disorders may reappear in patients under antiretroviral therapy, possibly with different clinical manifestations and at a different stage during HIV-infection. We discuss the appearance of the most common neurological complications in relation to the CD4-cell count during HIV-infection. The most frequent causes of seizures and headache in HIV-infected patients are shown. We recommend a systematic diagnostic work-up in patients with headache, starting from 3 typical clinical situations: focal signs, convulsions or altered mental status; no focal signs, CD4-cells > 200 microliters, meningism; fever and/or meningism, no focal signs. The analysis of the cerebrospinal fluid by polymerase chain reaction is now a well established diagnostic method for investigating the most common CNS-infections in AIDS-patients. Neuroimaging (by MRI or CT-scan) is an additional, useful investigation. Cerebral toxoplasmosis, cryptococcosis, PML, encephalitis due to herpes-viruses and neurosyphilis are discussed.

This study was undertaken to characterize the laboratory and clinical course of patients with AIDS and cryptococcal meningitis who had normal or elevated cerebrospinal fluid (CSF) pressure. Data were obtained retrospectively from a randomized multicenter quasifactorial phase III study comparing amphotericin B with or without flucytosine in primary treatment of cryptococcal meningitis. CSF pressure was measured before treatment and at 2 weeks. Repeated lumbar punctures were done to drain CSF and to reduce pressure. Patients with the highest baseline opening pressures (> or = 250 mm H2O) were distinguished by higher titers of cryptococcal capsular polysaccharide antigen in CSF; more frequently positive India ink smears of CSF; and more frequent headache, meningismus, papilledema, hearing loss, and pathological reflexes. After receiving antifungal therapy, those patients whose CSF pressure was reduced by >10 mm or did not change had more frequent clinical response at 2 weeks than did those whose pressure increased >10 mm (P<.001). Patients with pretreatment opening pressure <250 mm H2O had increased short-term survival compared with those with higher pressure. We recommend that opening pressures >/=250 mm H2O be treated with large-volume CSF drainage.

A 34-year-old female presented with spontaneous intracranial hypotension (SIH) manifesting as severe postural headache and meningism. Magnetic resonance (MR) imaging with gadolinium showed diffuse pachymeningeal enhancement. She developed bilateral chronic subdural hematomas 4 weeks after the onset of the symptoms. MR imaging showed descent of the midline structures of the brain. The bilateral chronic subdural hematomas were surgically drained, with no remarkable pressure. Postoperative MR imaging showed complete resolution of the pachymeningeal enhancement and relevation of the midline structures of the brain. SIH is an uncommon and probably unrecognized condition because of the usually benign course. However, this case emphasizes that SIH is not entirely benign. SIH should be considered if there is no identifiable risk for intracranial hemorrhage, particularly in young patients. Neurosurgical intervention for the treatment of the underlying cerebrospinal fluid leak may be required if SIH persists.

Cryptococcus neoformans is the leading cause of meningitis in patients with Acquired Immune Deficiency Syndrome (AIDS) and is associated with high mortality rate. Presenting symptoms include fever, nausea and vomiting, altered mentation, headache and meningismus. Cryptococcal meningitis is not infrequently complicated by raised intracranial pressure and visual sequelae (sometimes by blindness). In patients who survive the infection, the most debilitating outcome appears to be visual impairment or blindness. Management of impending visual complication combines medical and surgical treatment modalities. We report two cases of cryptococcal meningitis associated with visual impairment.
