Progressive symptomless hypothermia in water: possible cause of diving accidents Unexplained loss of consciousness, often followed by death, has been common during diving in British waters. Forty-two such deaths were noted by Childs and Norman" and no likely cause for them has been established. We describe here progressive symptomless hypothermia which developed during one of a series of fully ...

By contrast to this general perception, however, Botrytis species could frequently be isolated from the interior of multiple tissues in apparently healthy hosts of many species. Infection frequencies reached 50% of samples or more, but were commonly less, and cryptic infections were rare or absent in some ...

We report a family in which the father and all three children had symptomless chronic renal failure and, in the case of the children, normocytic, normochromic anaemia. None had hypertension, proteinuria, or abnormality of urinary deposit. Renal biopsy specimens showed microcysts confined to the renal cortex; some cysts contained vestigial glomerular tufts. This family appears to represent the f...

The condition is usually first noticed on routine examination of an otherwise normal fundus, and remains symptomless throughout l...
