“…Rothstein (1934) tuberculosis was given as the diagnosis in only 9, with one doubtful, the remainder being attributed to rheumatism or 'unknown' in roughly equal proportions. Other authors (Mortensen and Warburg, 1948;Kuipers, 1955;Vining, 1955;Dalton et al, 1956;Shea et al, 1957;Caddell et al, 1960) have presented small series of children, or included the occasional child in series of adults, but in these papers tuberculosis did not feature prominently as a proved cause. Even in countries where tuberculosis is common it probably only accounts for about half the number of cases (Das et al, 1973).…”
