Most fatal cases of Coxsackie group B neonatal myocarditis have been associated with nursery epidemics. Occasional sporadic cases have been reported, mainly from the U.S.A., and a further case with gross cardiomegaly is described.

In a recently conducted case-control study of sporadic cryptosporidiosis, 6.6% of subjects in the control group reported having had diarrhea in the 2 weeks before completion of the questionnaire. In an analysis of this control group, there was a very strong association between self-reported diarrhea and reported low water pressure at the faucet.

This paper studies, for p a prime, rank one isolated -minimal subgroups P in finite group G . Such share many of the features minimal parabolic groups Lie type. The structure Y , normal closure O ( ) is determined where smallest subgroup such that / -group. We find if ? and = 1 then either Z simple type characteristic or ? 7 with given by an explicit list. Of particular note twenty four out six...

Strains of group B meningococci isolated from cases of sporadic infection, epidemic infection, and from patients unassociated with clinical meningococcal infection have been examined by a serological typing technique. The majority of group B meningococci from clinical infections in the UK have serotype 2 antigen. Such strains were relatively uncommon among carriers who had no association with m...

The Nordstrom-Robinson code NR is a non-linear binary code of length 16, with 2 codewords and minimum distance 6. Its automorphism group is a semidirect product of an elementary abelian group of order 16 and the alternating group A7. This group and the corresponding action of A7 is also at the origin of the sporadic A7-geometry. We construct this geometry and derive the Nordstrom-Robinson code ...

Dura mater graft-associated Creutzfeldt-Jakob disease (dCJD) can be divided into two subgroups that exhibit distinct clinical and neuropathological features, with the majority represented by a non-plaque-type of dCJD (np-dCJD) and the minority by a plaque-type of dCJD (p-dCJD). The two distinct phenotypes of dCJD had been considered to be unrelated to the genotype (methionine, M or valine, V) a...

background: the most common neurologic manifestation of gluten sensitivity is ataxia, which accounts for up to 40% of idiopathic sporadic ataxia. timing of diagnosis of gluten ataxia is vital as it is one of the very few treatable causes of sporadic ataxia and causes irreversible loss of purkinje cells. antigliadin antibody (aga) of the igg type is the best marker for neurological manifestation...

A novel approach was used to estimate the in vivo mutation rate of the retinoblastoma gene. A mathematical formula can be used to calculate the probability of neoplasia induced by one or more mutations in a population of dividing cells. This formula can then be applied to epidemiological data on hereditary and sporadic retinoblastoma. The analysis yields an estimate of the in vivo mutation rate...

Abstract Let $G$ be a finite permutation group of degree $n$ and let ${\rm ifix}(G)$ the involution fixity , which is maximum number fixed points an involution. In this paper, we study almost simple primitive groups whose socle $T$ alternating or sporadic group; our main result classifies form with ifix}(T) \leqslant n^{4/9}$ . This builds on earlier work Burness Thomas, who studied case where ...
