RESUMO

Constipation and encopresis (fecal soiling) are common childhood disorders that may lead to significant functional impairment. The etiology and course of constipation and encopresis are increasingly conceptualized from a broad biopsychosocial perspective, and therefore a holistic approach to assessment and treatment is indicated. Many children experience symptoms of chronic constipation and/or encopresis that are only partially responsive to conventional medical therapy. Complementary/alternative therapies can often help in the treatment of constipation/encopresis and are well accepted by patients and families.

RESUMO

OBJECTIVE: The aim was to determine the presynaptic modulation of noradrenaline (NA) release from the sympathetic nerve terminals in human isolated papillary muscle. METHODS: Papillary muscle and the right atrial appendage were obtained from operations on 22 patients (10 men and 12 women). The papillary muscle preparations were preincubated with [3H]NA and the release of [3H] at rest and in response to field stimulation was measured. RESULTS: Using an immunohistochemical method dopamine-beta-hydroxylase-positive neurones were found in the papillary muscle and right atrial appendage sample. The release of noradrenaline from the papillary muscle, associated with axonal activity, was enhanced by 7,8(methylenedioxy)-14-alpha-hydroxyalloberbane HCl (CH-38083), a selective alpha 2 adrenoceptor antagonist, and inhibited by xylazine, an alpha 2 adrenoceptor agonist, indicating that negative feedback modulation was functioning. In addition, the release of [3H]NA was enhanced by atropine, pancuronium, and 4-diphenylacetoxy-N-methylpiperidine methiodide (4-DAMP), a selective M3 muscarinic receptor antagonist, and reduced by oxotremorine, a selective muscarinic receptor agonist, indicating that acetylcholine released from the parasympathetic nerve ending was able to reach the varicose noradrenergic axon terminals that are equipped with inhibitory M3 muscarinic receptors. CONCLUSIONS: These findings, obtained for the first time in human papillary muscle, indicate that the release of noradrenaline is modulated by alpha 2 autoreceptors activated by noradrenaline and M3 muscarinic heteroreceptors. Thus during parasympathetic stimulation the release of noradrenaline from the sympathetic axon terminals is presynaptically controlled through muscarinic receptors.

RESUMO

The controversy surrounding clinical observations and double-blind studies on homeopathic treatments is lessened when modern dynamical systems analysis is applied to high-dilution therapies. The logic of recurrent feedback loops, which applies to all dynamical network systems, inexorably leads to the systemic memory hypothesis - that complex patterns of emergent information and energy are stored to various degrees in physical, chemical, and biological systems. The addition of resonance, a dynamic pattern recognition process, explains many classic observations using high-dilution therapies. The systemic memory resonance hypothesis potentially provides a plausible biophysical mechanism for explaining not only how high-dilution therapies contribute to healing, but by extension, how information and energy in low-dilution and chemical therapies contribute to healing as well.

RESUMO

The principle of the similitude, the basis of homeopathy, has correspondences in the clinical studies of secondary effects of many modern pharmaceutical agents through the observation of the rebound effects of these drugs. Through clinical pharmacology, I proposed a model on which to base the scientificism of the homeopathic model. We have studied the effects of the drugs in the human body using pharmacological compendia and recent scientific works, confirming the mechanism of the homeopathic medicines' action through the verification of the primary action of the drugs and the consequent secondary reaction of the organism in hundreds of pharmaceutical agents. Treatment exploiting the "rebound" effect (curative vital reaction) may also be observed. This work suggests a research methodology to scientifically base the therapeutic principle of similitude.

RESUMO

The possibility of an interaction between diazepam and pancuronium bromide was investigated in six patients undergoing general anaesthesia maintained with fentanyl, droperidol and nitrous oxide. Neuromuscular blockade was controlled using a feedback mechanism which automatically adjusted the rate of injection of pancuronium to maintain between 71.4 and 72.9% blockade. Diazepam 0.14 mg kg-1 i.v. produced blood concentrations within the therapeutic range, but did not produce consistent changes in the level of blockade, pancuronium concentration in the blood or pancuronium consumption measured over 20 min.

RESUMO

A simple feedback control technique has been used to automatically deliver pancuronium to anaesthetised surgical patients. The dosage rate is automatically adjusted at 10-second intervals, according to the measured evoked, rectified, integrated electromyogram. When set to demand 80 percent blockade, in 40 patients, the controller maintained blockade at a steady mean level of 72.9 percent (consuming pancuronium at a mean rate of 0.47 microgram/kg/minute). The main clinical practical problems involved protection against electrical noise and the need to spend time setting up the equipment.
