RESUMO

Stress substantially increases the risk of developing painful temporomandibular disorders (TMDs) by influencing the release of endogenous catecholamines. Propranolol, an antagonist of ß-adrenergic receptors, has shown potential in alleviating TMD-associated pain, particularly when the level of catecholamines is elevated. The aim of this study was to explore whether intra-articular propranolol administration is effective in diminishing temporomandibular joint (TMJ) pain during repeated stress situations. Additionally, we investigated the effect of repeated stress on the expression of genes encoding ß-adrenoceptors in the trigeminal ganglion. In the present study, rats were exposed to a stress protocol induced by sound, then to the administration of formalin in the TMJ (to elicit a nociceptive response), followed immediately afterward by different doses of propranolol, after which the analgesic response to propranolol was evaluated. We also assessed the levels of beta-1 and beta-2 adrenergic receptor mRNAs (Adrb1 and Adrb2, respectively) using reverse transcription-quantitative PCR (RT-qPCR). Our findings revealed that propranolol administration reduces formalin-induced TMJ nociception more effectively in stressed rats than in non-stressed rats. Furthermore, repeated stress decreases the expression of the Adrb2 gene within the trigeminal ganglion. The findings of this study are noteworthy as they suggest that individuals with a chronic stress history might find potential benefits from ß-blockers in TMD treatment.

RESUMO

OBJECTIVES: The 2012 Surviving Sepsis Campaign pediatric guidelines recommend stress dose hydrocortisone in children experiencing catecholamine-dependent septic shock with suspected or proven absolute adrenal insufficiency. We evaluated whether stress dose hydrocortisone therapy in children with catecholamine dependent septic shock correlated with random serum total cortisol levels and was associated with improved outcomes. DESIGN: Retrospective cohort study. SETTING: Non-cardiac PICU. PATIENTS: Critically ill children (1 mo to 18 yr) admitted between January 1, 2013, and December 31, 2013, with catecholamine dependent septic shock who had random serum total cortisol levels measured prior to potential stress dose hydrocortisone therapy. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The cohort was dichotomized to random serum total cortisol less than 18 mcg/dL and greater than or equal to 18 mcg/dL. Associations of stress dose hydrocortisone with outcomes: PICU mortality, PICU and hospital length of stay, ventilator-free days, and vasopressor-free days were examined. Seventy children with catecholamine-dependent septic shock and measured random serum total cortisol levels were eligible (16% PICU mortality). Although 43% (30/70) had random serum total cortisol less than 18 µg/dL, 60% (42/70) received stress dose hydrocortisone. Children with random serum total cortisol less than 18 µg/dL had lower severity of illness and lower Vasopressor Inotrope Scores than those with random serum total cortisol greater than or equal to 18 µg/dL (all p < 0.05). Children with stress dose hydrocortisone had higher severity of illness and PICU mortality than those without stress dose hydrocortisone (all p < 0.05). Mean random serum total cortisol levels were similar in children with and without stress dose hydrocortisone (21.1 vs 18.7 µg/dL; p = 0.69). In children with random serum total cortisol less than 18 µg/dL, stress dose hydrocortisone was associated with greater PICU and hospital length of stay and fewer ventilator-free days (all p < 0.05). In children with random serum total cortisol greater than 18 µg/dL, stress dose hydrocortisone was associated with greater PICU mortality and fewer ventilator-free days and vasopressor-free days (all p < 0.05). CONCLUSIONS: Stress dose hydrocortisone therapy in children with catecholamine-dependent septic shock correlated more with severity of illness than random serum total cortisol levels and was associated with worse outcomes, irrespective of random serum total cortisol levels.

O diagnóstico mais comum foi o acidente vascular encefálico (29,4%), seguido das pneumopatias (23,5%); 89,4% necessitaram de suporte ventilatório invasivo, 98,9% usaram sonda nasogástrica, 92,9% sonda vesical de demora, 92,9 % utilizaram acesso venoso central e 90,6% fizeram uso de antibióticos. Quanto aos níveis pressóricos, apenas 4,9% apresentaram normalidade; a noradrenalina foi a DVA mais utilizada (67,1%), seguida da dopamina (35,3%); 64,7% evoluíram para óbito.

RESUMO

Obesity is highly prevalent and has several adverse effects on health. Its treatment is thus warranted and must aim to modify dietary and physical activity habits. The opinion of this association is that anorexigenic drugs with cathecolaminergic action (diethylpropion, phentermine, mazindol and phenylpropanolamine) or serotoninergic action (fenfluoramine and fluoxetine) may be used in moderate or severe obesity (BMI > 30 kg/m2) after a complete clinical assessment and in the context of an integral medical treatment. This association recommends a close surveillance of the use of these drugs, specially when formulated as non-proprietary prescriptions.

RESUMO

The hemodynamic effects of dobutamine were studied in 33 infants and children with cardiogenic or septic shock. Dobutamine was administered at doses of 2.5, 5.0, 7.5, and 10.0 micrograms/kg/minute. Significant increases above preinfusion values were observed in cardiac index, left ventricular stroke work index, and pulmonary wedge pressure. Significant decreases from preinfusion values were observed in systemic arteriolar resistance index. No significant differences occurred in heart rate, mean systemic arterial pressure, mean pulmonary arterial pressure, right atrial pressure, or pulmonary arteriolar resistance index. Analysis of the data also revealed significant effects of age and diagnosis on the hemodynamic responses. These data suggest that dobutamine is a useful drug in the pharmacologic management of children in shock, especially in children older than 12 months with cardiogenic shock not complicated by severe hypotension.
