[Blood pressure variability and morbidity].

In a previous study (resting blood pressure profile, Dinamap) we have confirmed the correlations between blood pressure and left ventricular mass (myocardial hypertrophy being one of the morbidity criteria in Hypertension) and we have demonstrated the absence of significant difference (Fisher's z Test) with the results of ambulatory recordings found in literature. Furthermore, we have showed a weaker correlation between absolute variability (AV) and left ventricular mass (LVM). If indeed there exists a cause-effect relationship between the AV increase and the LVM increase, a relative independence between VA and blood pressures mean (mBP) should still be demonstrated.

[Relationship between heart mass and semi-ambulatory pressure profiles].

This work was undertaken with 420 patients (90 normotensives: casual blood pressure less than or equal to 140/90 mmHg and 330 hypertensives) in which was recorded a semi ambulatory blood pressure profile (Dinamap 8AM-8PM, a reading every fifteen minutes). On the same day an echocardiogram was performed. We have correlated the left ventricular mass, the left ventricular mass index, the interventricular septum, the left ventricular cavity volume and the left ventricular posterior wall with casual blood pressure, average daily blood pressure standard deviation and variation coefficient for mean blood pressure, systolic blood pressure and diastolic blood pressure.

[Blood pressure variation].

A blood pressure profile at rest was recorded in 2,000 patients (1,069 females, 931 males) by DINAMAP 845 (from 8 AM to 8 PM. a record every fifteen minute). The limit between normotensive and hypertensive patients in this settled by WHO (BP = 160/95 mmHg).

[Analysis of 1,400 blood pressure profiles].

Hypertension may be defined by 3 criteria obtained by indirect, non invasive, automatic measurement of blood pressure using the DINAMAP device analyses the profile obtained over a 12 hour period (one recording every fifteen minutes): percentage of abnormal values (BP greater than 160/95 mm Hg), average values of systolic, diastolic and mean BP, variability (standard deviation of means), The analysis was based on 1,400 profiles recorded from 174 normotensive and 1,226 hypertensive patients. The following observations were made: the largest group was that of patients with predominantly diastolic hypertension under 60 years of age (81.3 p.

[Congenital esophagotracheal fistulas without esophageal atresia in children].

Ten cases are reported of children presenting isolated, congenital esophagotracheal fistulae without esophageal atresia, or "H-type-fistula" of Anglo-Saxon authors. The malformation is rare, of difficult diagnosis and often associated with other malformations. Respiratory symptomatology is sometimes dramatic, but diagnosis is based on data from radiologic imaging of the esophagus and from esophageal and tracheobronchial endoscopy.
