Cerebral Palsy in Children as a Risk Factor for Malnutrition.

Aim: The main aim of this study was to determine some malnutrition risk factors among children with cerebral palsy (CP). Children with CP often require the assistance of physical therapy centers. Experience suggests that, apart from physical disabilities, this group often suffers from malnutrition.

[Maple Syrup Urine Disease in a newborn infant].

Maple Syrup Urine Disease (MSUD) is a severe metabolic disorder secondary to an enzyme defect in the catabolic pathway of the branched chain amino acids: leucine, isoleucine and valine. Accumulation of these amino acids and derived from them alpha-keto-acids leads to encephalopathy and progressive degeneration of the nervous system in undiagnosed and hence untreated patients. Early diagnosis and elimination diet prevent complications and therefore create a possibility of both normal intellectual and physical progress.

H2O2 and Src-dependent transactivation of the EGF receptor mediates the stimulatory effect of leptin on renal ERK and Na+, K+-ATPase.

We examined the mechanism through which leptin increases Na(+), K(+)-ATPase activity in the rat kidney. Leptin was infused under anaesthesia into the abdominal aorta proximally to the renal arteries and then Na(+), K(+)-ATPase activity was measured in the renal cortex and medulla. Leptin (1mug/kgmin) increased Na(+), K(+)-ATPase activity after 3h of infusion, which was accompanied by the increase in urinary H(2)O(2) excretion and phosphorylation level of extracellular signal regulated kinase (ERK).

Indirect CT venography of the abdominal cavity and lower limbs in patients with the suspicion of pulmonary embolism--indications, technique, diagnostic possibilities.

Multi-slice computed tomography has become the main method to diagnose and evaluate the intensity of acute pulmonary embolism (PE). The most common cause of PE is thrombosis of veins of the lower limbs and pelvis. The paper presents various aspects of the use of combined pulmonary artery arteriography and indirect venography performed using multi-slice tomography in relation to other methods imaging the venous system used so far.
