While this is a T3 tumor, it is not stage I. Once, a tumor has invaded beyond the muscular propria, it is deemed at least a Stage II tumor. In this case, because there is no lymph node involvement or metastases, the tumor is Stage IIA. +
Computed Tomography of the chest would subject the patient to unnecessary radiation and take longer than a chest radiograph. +
Serum glucose >200 is one of Ranson's criteria. Hyperglycemia can occur in she pancreatitis due to a decrease in insulin secretion from pancreatic beta cells. +
Patients with injuries from seat belts often carry the "seat belt sign", a triangle of skin abrasions covering the neck chest and abdomen. The car was likely traveling too slowly (15 mph) for a seatbelt collision to be a reasonable source of the shoulder injury in this patient. +
Anterior cord syndrome is caused by injury to the anterior part of the spinal cord. These lesions typically affect the corticospinal tract and the spinothalamic tract. Therefore, patients frequently have paralysis and loss of pain/temperature below the level of the lesion. Because proprioception and vibration travel in the posterior aspect of the spinal cord, they are unaffected. +
Acetazolamide is the therapy of choice in treating idiopathic intracranial hypertension. Acetazolamide . Also, keep in mind that his blood pressure is 105/70, meaning that his mean arterial pressure is 82. Recall that the cerebral perfusion pressure is MAP-ICP = CPP. Therefore the cerebral perfusion pressure in this case is 54 (82-28). In the ICU, cerebral perfusion pressure is typically maintained between 50-70 mmHg. Lowering the patient's blood pressure further would put the patient at risk of cerebral hypoperfusion and ischemia. +
Calcium binding to the troponin C subunit is involved in the contraction of cardiac muscles rather than smooth muscles. +
Explosive manufacturing may be associated with nitroglycerin exposure, intoxication, and tolerance. +
Atenolol is a non-selective beta blocker. Beta blockers are typically associated with bradycardia and dyslipidemia. +
Non-dihydropyridine calcium channel blockers are not effective in the management of Raynaud's phenomenon. +
During normal fetal development, cells from the neural crest migrate into the colon to form Auerbach's plexus and Meissner's plexus. In Hirschprung's disease, the migration is not complete, and part of the colon lacks these nerve bodies that regulate the activity of the colon. The affected segment of the colon cannot relax and may result in meconium ileus. +
The epothilones resemble taxanes in that they bind to beta-tubulin and trigger microtubule nucleation and cell-cycle arrest at the G2-M interface. Epothilones bind to a site distinct from that of taxanes. Ixabepilone is approved for metastatic breast cancer treatment. +
Pituitary prolactinoma is a benign tumor of the pituitary gland. It is the most common type of pituitary tumor. Symptoms of prolactinoma are either caused by hyperprolactinemia or by pressure of the tumor on surrounding tissues. Prolactinoma and other pituitary tumors may be associated with type 1 multiple endocrine neoplasia. +
