BACKGROUND: The cardiovascular risk (CVR) is increasing and it is related to life style and dietary habits; one of the age groups at risk of developing this disease are the obese children. The objective of this study was to assess the CVR in the obese pediatric population in a secondary care unit of the Instituto Mexicano del Seguro Social in San Luis Potosí, México. METHODS: A cross-sectional study, in which we used Alústiza's scale to measure CVR. We included the total of cases of pediatric obese population in a year...

The effect of excercise on brain function was investigated through animal experiments. Exercise leads to increased serum calcium levels, and the calcium is transported to the brain. This in turn enhances brain dopamine synthesis through a calmodulin-dependent system, and increased dopamine levels regulate various brain functions. There are abnormally low levels of dopamine in the neostriatum and nucleus accumbens of epileptic mice (El mice strain) and spontaneously hypertensive rats (SHR). The low dopamine levels in those animals were improved following intracerebroventricular administration of calcium chloride...

Pulmonary hemodynamics and gas exchange were studied in four physicians during 72 hr acclimatization to 12,470 ft. Pulmonary catheters were left in three subjects for 72 hr. Resting mean pulmonary arterial pressure (PAP) rose progressively during the first 24 hr from 10.3 +/-1.0 to 21.1 +/-4.0 torr and remained at this level. During this same 24 hr period cardiac output increased from 7.1 +/-1.4 to 8.4 +/-2.0 liters/min and total pulmonary resistance rose from 122 +/-16 to 209 +/-40 dynes.sec/cm(-5). Excercise at 60 w after 24 hr of hypoxia increased PAP to 28...

The authors modified the Valsalva test by employing a strictly staged dosed loading with the help of a water manometer for recording rheopneumogrammes in normal individuals and in pulmonary patients. In the absence of clinical signs of cardiac pathology this method permitted to reveal latent disorders in the contractility of the right heart and its reserve capacity. The shifts in the rheographic data of the patients differed significantly from those obtained in the normals. The obtained data indicate that the intrathoracic pressure plays a certain role in the development of pulmonary hypertension...

Impact between the brain and the cristae of the base normally results as a consequence of inertia when an obstacle is hit, followed by contusion, or intra-, sub- or extradural haematoma. The skull itself may be briken (usually at the interpilasters or the weak points of the pilasters) or dented. Denting resulted in the depression of a circular fragments or fragments, with compression of the dura mater or brain; this, in turn, may be contused, lacerated or even crushed. Spinal crash fractures usually involve the lumbar region...
