RESUMEN
Cryptococcus is a cosmopolitan fungus with tropism for the nervous system and a higher prevalence of infection in immunosuppressed patients. Neurological compromise caused by this microorganism mainly debuts as a meningeal syndrome (headache, fever, neck stiffness) with predominant encephalic involvement. In this report we present the rare case of a non-HIV patient with flaccid paralysis and peripheral nerve involvement due to crytpococcal meningitis. This is a 53-years-old woman, with a past-medical history of diabetes, who presented with dysarthria, unilateral peripheral facial paralysis, asymmetric ascending quadriparesis, generalized hyporeflexia and urinary retention. Neuroimaging was initially reported as negative for vascular or demyelinating diseases. Electrophysiological studies were performed, and acute flaccid paralysis of undetermined etiology was defined as a temporal clinical diagnosis. Cerebrospinal fluid molecular analysis confirmed the presence of Cryptococcus neoformans var. gatti; posteriorly, antifungal treatment with amphotericin B and fluconazole was started. Polyneuroradiculopathy symptoms significantly improved over the in-hospital stay. In conclusion, spinal cord and peripheral nerve involvement by Cryptococcus is an infrequent cause of acute flaccid paralysis that should be considered in the differential diagnosis even in HIV-negative patients.

Acute flaccid paralysis is associated with inflammation, infection, or tumors in the spinal cord or peripheral nerves. Melioidosis (Burkholderia pseudomallei infection) can rarely cause this presentation. We describe a case of spinal melioidosis in a 4-year-old boy presenting with flaccid paralysis, and review the literature on this rare disease.

BACKGROUND AND OBJECTIVE: No recent publications are available about pneumococcal meningitis in Hungarian children. The aim of this study was to collect data of epidemiological, clinical and prognostic features of pneumococcal meningitis in children treated at Szent László Hospital, Budapest, Hungary. METHODS: We conducted a retrospective review of medical charts and follow-up records of patients aged 1 to 18 years admitted to our Pediatric and Pediatric Intensive Care Units due to pneumococcal meningitis between 1st Jan 1998 and 30th Jun 2007. RESULTS: 31 children with 34 cases of pneumococcal meningitis were admitted to our hospital in the study period. Two children developed recurrent illness. The mean age was 6 years, 26% were under 1 year of age. The mean duration of hospital stay was 21 days, 97% required intensive care. Frequent clinical symptoms were fever (100%), nuchal rigidity and vomiting (78%), altered mental status (71%), Kernig's and Brudzinski's signs (58%) and seizures (41%). Otitis media, sinusitis, mastoiditis were present in 44%, 58%, 41%, respectively. Subdural effusion, parenchymal cerebral lesion and sinus thrombosis were documented in 5, 3 and 2 cases, respectively. One third of the patients received ceftriaxon, two thirds were administered ceftriaxon and vancomycin. Adjunctive therapy with dexamethasone was given to 91% of the children. 70% of patients required mechanical ventilation. 9 patients (25%) required endoscopic sinus surgery. In 13 cases (38%) mastoidectomy, in 5 children (15%) neurosurgery was performed. The case fatality rate was 23.5%. 8 (23.5%) patients had mild or moderate, 1 child (3%) developed severe neurological sequelae. CONCLUSION: Pneumococcal meningitis in children remains a source of substantial morbidity and mortality in childhood. The long hospital stay, the frequent need for intensive care and severe neurologic sequelae emphasize the importance of early diagnosis, early treatment and prevention with pneumococcal conjugate vaccines.

In five years from 1988 to 1992, 51 polioviruses were isolated from patients with acute flaccid paralysis in Shandong province in China. Of the 51 poliovirus isolates, 17 were type 1, 18 type 2 and 16 type 3. Twelve type 1 viruses isolated during the period from 1988 to 1990 were shown to be wild strains by serology and the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods. These wild strains were classified into three groups by PCR-RFLP. The other type 1 isolates were Sabin-like strains. No wild strain was isolated in 1991 or 1992. All isolates of types 2 and 3 during the five years were Sabin-like strains. These data suggest that wild strains of polioviruses will soon be eradicated in Shandong province.

In 1985, the Pan American Health Organization adopted the goal of eradication of poliomyelitis from the Americas by 1990. Strategies to accomplish this included high vaccination coverage, aggressive outbreak control, and active surveillance for acute flaccid paralysis (AFP). Although the sensitivity of AFP surveillance for detecting paralytic poliomyelitis cases is high, studies have shown the specificity to be low. In 1990, 2497 notified cases of AFP were investigated in the Americas of which 2146 had stool specimens collected. However, only 18 were confirmed as poliomyelitis by isolation of wild poliovirus from stool specimens, 71 were classified as being compatible with poliomyelitis. Cases of AFP due to causes other than poliomyelitis result in extensive but unnecessary outbreak control measures. To predict, at initial clinical evaluation, the likelihood of future confirmation as a case of poliomyelitis, likelihood ratios (LR) were calculated for different combinations of clinical characteristics of AFP cases (249) from Mexico in 1989 and 1990. The best predictors in a child with AFP were proximal muscle involvement which progressed '4 days together with fever at onset of paralysis, and proximal and unilateral involvement with either fever at onset or paralysis which progressed '4 days. The odds would increase by 12 that the child would eventually be confirmed as poliomyelitis (19), based on a stool culture positive for wild poliovirus (95% confidence interval (CI) 2.6-55.9). A guide for use in the field is proposed whereby local health officials, often with little training in neurological evaluation, can predict at initial clinical examination the likelihood that an AFP case will subsequently be confirmed as poliomyelitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Fifteen premature infants with lethal congenital cytomegalovirus infection were studied to determine the clinical, neuroradiological, and neuropathological characteristics of the disease in this population. Nine infants were liveborn but died at a postnatal age of 18 +/- 21 days; 6 infants were stillborn. Clinical findings in liveborn infants included microcephaly (77%), seizures (55%), hypotonia (33%), and multiple contractures (18%). Ophthalmological findings included chorioretinitis, optic atrophy, and corneal opacities. Neuroradiological findings included the postnatal evolution of periventricular calcification in 1 infant, and cerebellar hypoplasia diagnosed by magnetic resonance imaging in 1 infant. Neuropathological findings included periventricular necrosis and calcification (12), associated diffuse calcification frequently involving the convexity of the gyri (6), cerebellar hypoplasia (5), periventricular leukomalacia (2), intraventricular hemorrhage (2), hydrocephalus (2), and porencephalic cyst (1). Intranuclear inclusion bodies within the brain were observed in 4 infants, whereas systemic inclusion bodies were present in all infants. These data indicate several atypical findings in preterm infants rarely reported in term infants, including hypotonia, multiple contractures, periventricular leukomalacia, and optic atrophy.

Experimental amyotrophic leukospongiosis (ALSP) has first been reproduced in 2 squirrel monkeys 16 and 23 months after inoculation of the animals with a brain suspension from the patient who had died of this disease. From the brain cell cultures of the monkeys a hemadsorbing agent was isolated which induced cell proliferation and was inhibited by the antisera from patients with ALSP.

Crystalline arrays of so-called 'virus-like particles' were found in post-mortem samples of skeletal muscle obtained from an 11-month-old female infant. In a large number of skeletal muscle fibres crystalline inclusions were abundant, variously configurated and positively stained with a cytochemical method for polysaccharides. A battery of enzymatic tests, including some with diastase and alpha-amylase, was, however, entirely noncontributory. A muscle biopsy studied 5 months before death had disclosed no crystalline inclusions of any kind. The literature concerning similar cases of 'virus-like particles', crystalline glycogen aggregates or protein-glycogen complexes in muscle is reviewed. Possible reasons underlying the aggregation of protein-glycogen complexes into crystalline arrays are discussed.
