The muscarinic receptor subtype-activated signal transduction mechanisms mediating rat urinary bladder contraction are incompletely understood. M(3) mediates normal rat bladder contractions; however, the M(2) receptor subtype has a more dominant role in contractions of the hypertrophied bladder. Normal bladder muscle strips were exposed to inhibitors of(More)
BACKGROUND Recently, interest has emerged in the sensation of irritation that precedes the motor act of coughing; this phenomenon has been termed the urge-to-cough (UTC). Although one previous study has demonstrated a transient enhancement of cough reflex sensitivity during acute upper respiratory tract infection (URI), the effect of URI on UTC has not(More)
Cough is among the symptoms most commonly associated with an acute, viral upper respiratory tract infection (URI), such as the common cold. Two previous studies incorporating capsaicin cough challenge methodology have demonstrated that cough reflex sensitivity is transiently enhanced during URI. These studies used single measurements of cough reflex(More)
Primary salivary type lung cancer are extremely rare intrathoracic malignancies. Mucoepidermoid tumor is one of the salivary gland tumor which originates from submucosal glands of tracheobronchial tree. These are very slow growing low grade malignant tumors. Surgery is the mainstay of treatment and rarely requires adjuvant therapy. In this case report, we(More)
A 44 year old male former smoker from Ecuador presented with productive cough for 3 weeks, positive tuberculin skin test, 40 lbs weight loss and right lower lobe collapse. He denied wheezing or hemoptysis. He was treated with antibiotics and ruled out for tuberculosis with negative sputum smear. Bronchoscopy showed an endobronchial lesion at the distal end(More)
Acute catecholamine cardiomyopathy is an uncommon, life-threatening manifestation of pheochromocytoma. The massive release of catecholamines from the adrenal medulla and their toxic effects on the coronary vessels and the cardiac myocytes play a significant role in the pathogenesis of cardiomyopathy in patients with pheochromocytoma. Severe manifestations,(More)
Primary mucoepidermoid tumors of the lung are rare entities. Synchronous primary malignancies of the lung involving mucoepidermoid carcinoma and mucinous adenocarcinoma are even rarer and constitute a unique set of patient population. The presentation, diagnosis and treatment strategies for this patient population are not well described. In most cases, the(More)
