An unusual case is reported where a thrombus over a myocardial infarction gave rise to an embolus which lodged in the same coronary art,ery in which an earlier thrombus had resulted in the infarction. This coronary embolus caused sudden death of the patient. KATZ.

1938.
A standard smoking test and a control test have been carried out on patients with essential hypertension and thirty subjects with normal blood Cigarette smoke produced an elevation of blood pressure in the majority dividuals tested by a standard smoking test. The excessive rises in blood from smoking occurred only in the patients who had evidence of an inherently reactive vascular system as measured by the cold pressor test. The effect of tobacco on the blood pressure, however, is not due entirely to a nonspecific acting on a hyperreactive vascular system but is the result, at least in part, element in the tobacco smoke which produces vasoconstriction.

A study has been made of the effects of blood pressure raising reflexes in normal subjects, patients with essential hypertension, and patients with renal hypertension. Two different methods of testing the blood pressure raising reflexes were employed: (1) the stimulus of exercising the forearm muscles during arrest of the circulation as previously described by the authors; (2) a modification of the cold pressor test Effects on the blood pressure were similar with as described by Hines and Brown. both tests.

The rise in both systolic and diastolic pressures is less in patients with renal hypertension than in normal subjects of the same age group.

No definite correlation was found between a high degree of reactivity and the resting blood pressure level. In the majority of cases of essential hypertension the natural relationship between the pulse rate and blood pressure is reversed in that a rise in blood pressure is accompanied by a rise in pulse rate.

There seems to be a definite relationship between periarteritis nodosa and rheumatic fever, and it is possible that the former disease is in some cases an allergic response to the agent of rheumatic fever. Three cases of periarteritis nodosa were found in 4,000 autopsy cases in two Australian hospitals. One of these three cases presented rheumatic vegetations on the mitral valve. Allusion is made to previous cases with associated rheumatic manifestations. The cause of periarteritis nodosa, of course, has not been proved. MONTGORZERY.

The cases are reported of twenty-two individuals with thromboangiitis obliterans who died, including nine on whom necropsy was performed. In sixteen cases, or 73 per cent of the group, extraperipheral vascular lesions played a dominant role as the cause of death. Four of these deaths followed operation. Coronary thrombosis is by far the most common type of peripheral lesion producing death in cases of thromboangiitis obliterans. In none of the post-mortem cases was a lesion found in the visceral arteries which was typical of the pathologic changes described by Buerger. AUTHORS.
