hypothyroidism/hypoxia

The purpose of this study was to investigate the role of peripheral chemoreceptor activity on the hypoxic and hypercapnic ventilatory drives in rabbits with induced hypothyroidism. Experiments were carried out in control and hypothyroid rabbits. Hypothyroidism was induced by an administration of an

We studied the effect of intermittent hypobaric hypoxia on morphofunctional characteristics of the thyroid gland during experimental hypothyroidism. Functional activity of the thyroid gland increased in the early period of hypoxia. Morphofunctional parameters reached a constant level with increasing

Hypothyroidism can depress breathing and alter dopamine D2 receptor expression and function. We hypothesized that relative to euthyroid hamsters (EH), hypothyroid hamsters (HH) contain increased D2 receptors in brain regions associated with breathing and carotid bodies (CB), and that stimulation of

To define the prevalence of impaired ventilatory responses in hypothyroidism, clinical and chemical parameters predicting their presence, and the potential for their acute reversal, ventilatory responses to hypercapnia and hypoxia were studied in 38 hypothyroid patients before treatment, and after

Congenital hypothyroidism is a clinical condition characterized by lack of thyroid hormone because of thyroid gland developmental and thyroid hormone biosynthesis disorders. The most common cause of permanent hypothyroidism is congenital factors. Prompt diagnosis is critical. However, overt signs of

OBJECTIVE Patients with severe hypothyroidism present unique challenges to anesthesiologists and demonstrate much increased perioperative risks. Overall, they display increased sensitivity to anesthetics, higher incidence of perioperative cardiovascular morbidity, increased risks for postoperative

Laboratory experiments have demonstrated that tetra- and triiodothyronine (T4, T3) enhance hypoxia-induced erythropoietin (Epo) production. In the present study serum immunoreactive Epo was measured in 29 patients with hyperthyroidism and in 10 patients with hypothyroidism. Epo levels were inversely

Primary sleep apnea-hypopnea syndrome (obstructive sleep apnea [OSA]) and hypothyroidism have many signs and symptoms in common. The overlap in clinical presentation, and the sleep-disordered breathing that can accompany hypothyroidism, create a significant risk of misdiagnosis of sleep apnea among

Changes in platelet indices (platelet count and platelet size) and PCV associated with thyroid disease were studied in 7 dogs with hypothyroidism and 21 cats with hyperthyroidism that were admitted to the veterinary teaching hospital. Compared with control (euthyroid) dogs, dogs with hypothyroidism

OBJECTIVE The effects of triiodothyronine (T(3)) and hypoxia on 2,3-bisphosphoglycerate (2,3-BPG) studied in vitro are unclear. To clarify these effects we selected a more physiologic approach: the in vivo study in rabbits. We also present the changes produced by T(3) and hypoxia on phosphoglycerate

Childhood cases of myxedema coma are extremely rare. We report a case of a 5-year-old girl transferred to a tertiary care pediatric emergency department with hypoxemia and altered mental status and diagnosed with severe hypothyroidism and myxedema coma in the setting of acute influenza infection.

Nineteen patients with overt hypothyroidism were examined for the prevalence of myocardial disfunction, respiratory disturbances, peripheral neuropathy, and visual failure due to pituitary enlargement. Prevalences of pericardial effusion and myocardial disfunction (decrease PEP/LVET) were 50% and

We report a case of hypothyroidism, obstructive sleep apnea (OSA) with persistent daytime hypoxemia. Cause of hypoxemia was two arteriovenous (AV) malformations in the lower lobe of the lung. We must be alert to other causes of hypoxemia in patients of OSA with persistent daytime hypoxemia.
