The purpose of this study was to determine the frequency of hypoxemia and pulmonary mineralization using 99mTc-methylene diphosphonate (99mTc-MDP) in dogs with pituitary-dependent hyperadrenocorticism (PDH). Twenty-one dogs with PDH were prospectively evaluated using thoracic radiography, arterial
A 6-year-old, spayed female dog was evaluated for a history of chronic coughing, excessive panting, and lethargy. Iatrogenic hyperadrenocorticism was diagnosed, and pulmonary mineralization was documented with a 99m Technitium-methylene diphosphonate (99mTc-MDP) scan. Blood gas analysis showed
Varying degrees of respiratory distress developed in 3 dogs in which hyperadrenocorticism was diagnosed. The respiratory distress was attributed to pulmonary artery thrombosis. Radiography revealed pleural effusion, increased diameter and blunting of the pulmonary arteries, lack of perfusion of the
OBJECTIVE
To report the management of a dog that required 2 treatments with mechanical ventilation; firstly for severe tracheal collapse and secondly following deployment of a nitinol tracheal stent that immediately preceded a nonoxygen responsive pulmonary thromboembolism (PTE), suspected to have
Chronic increases in cortisol inhibit basal plasma arginine vasopressin (AVP). Acute pretreatment with cortisol inhibits the large increase in AVP during hypotension or hypoxia but does not inhibit the modest increase in AVP in response to hypertonic saline (HS). We evaluated the effect of a chronic
Pulmonary surfactant is synthesized by type II alveolar epithelial cells to regulate the surface tension at the air-liquid interface of the air-breathing lung. Developmental maturation of the surfactant system is controlled by many factors including oxygen, glucose, catecholamines, and cortisol. The
BACKGROUND
Obstructive sleep apnea (OSA) is a common sleep-related respiratory disorder. It is associated with many endocrinopathies including hypogonadotropic hypogonadism, hypercortisolism, and glucose intolerance that may lead to bone loss with secondary osteoporosis.
METHODS
We report the case
Adrenal steroids, besides acting on the pituitary and the hypothalamus to exert classical feedback activity, can also have endocrine and extra-endocrine actions at the level of sub-cortical areas, as the hippocampus and the amygdala, involved in cognition and effectiveness. Acting on the
Adrenococortical carcinoma (ACC) is a rare cancer, occurring at the rate of one case in two million person years. Cushing syndrome or a mixed picture of excess androgen and glucocorticoid production are the most common presentations of ACC. Other uncommon presentations include Medical records of 47 dogs with pulmonary thromboembolism were reviewed. Middle-aged to older dogs predominated and dyspnea and arterial hypoxemia were consistent clinical findings. Thoracic radiographic findings were variable. Cardiac disease, neoplasia, hyperadrenocorticism, disseminated
We report a 55-year-old woman with typical clinical, biochemical and radiological features of Cushing's disease, who developed a severe respiratory insufficiency as the main symptom. She also complained of proximal muscle weakness over the last year and progressive dyspnea over the last four months.
BACKGROUND
Previous studies have shown that major depression is frequently accompanied by hypercortisolemia. There is some evidence suggesting that an increase in the glucocorticoid levels may make hippocampal cells more vulnerable to insults caused by hypoxia, hypoglycemia, or excitatory
Accumulating data suggest that prenatal compromises leading to intrauterine growth restriction (IUGR) increase the risk for respiratory deficiencies after birth. In this respect, a growing body of epidemiological evidence in infants, children and adults indicates that small for gestational (SGA)
