[Pathological modifications of the P wave due to probable primary changes in intra-atrial conduction]. / Modificazioni patologiche della P da probabili alterazioni primitive della conduzione intra-atriale.

Two cases of variable changes in ECG P oscillation not due, as is usually the case, to familiar cardiac or respiratory conditions suggested a review of the literature on the subject. It is concluded that these anomalies are the result of changes in the intra-atrial conduction of the stimulus through preferential ways or to aberrant atrial conduction. These are situations of no little practical interest because they may be precursors of major rhythm disturbances such as atrial flutter or atrial fibrillation.

[Echinococcal cysts of the adrenal glands. Review and diagnostic discussion]. / Le cisti da echinococco delle ghiandole surrenali. Inquadramento e discussione diagnostica.

Observation of an exceptional case of hydatid cyst of the suprarenal gland triggered an extensive review of the literature on the subject and an analysis of the disease from a historical-statistical, biological, aetiopathogenic, anatomopathological and clinical point of view. All these were analysed as an aid to diagnosis which is always difficult despite the many effective diagnostic tools now available. The difficulty derives essentially from the rarity of the condition and the fact that its clinical features often appear not to confirm or to underestimate the initial diagnostic suspicion.
