Thyroid nodules are solid or fluid-filled lumps that form within your thyroid, a small gland located at the base of your neck, just above your breastbone. The great majority of thyroid nodules aren't serious and don't cause symptoms. Thyroid cancer accounts for only a small percentage of thyroid nodules. You often won't know you have a thyroid nodule until your doctor discovers it during a routine medical exam. Some thyroid nodules, however, may become large enough to be visible or make it difficult to swallow or breathe.

The most reliable clinical sign to detect ascites is checking for bilateral flank dullness. If a patient with ascites is lying supine, fluid accumulates in the flank regions, leading to dullness on percussion. At the same time, the air-filled bowel loops are forced upwards by the free fluid due to buoyancy, resulting in tympanitic percussion. To locate specifically where dullness shifts to tympany, or the air-fluid level, percussion should be performed from the sides towards the middle. To confirm that the dullness is caused by ascites, ask the patient to switch to a lateral decubitus position. If ascites is present, the air-filled bowel loops will shift accordingly and remain at the surface of the fluid. As a result, the air-fluid level will shift as well. This is known as shifting dullness.

Endovascular Aneurysm Repair Endovascular aneurysm repair (or endovascular aortic repair) (EVAR) is a type of endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA).

Urinary System Structure and Function

Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The function of pulmonary circulation is to exchange carbon dioxide for oxygen in the blood. It is the passage of blood from the heart to the capillaries of the lungs, where the gases are exchanged, and back to the heart to be pumped around the body.

Radiosurgery: Radiosurgery devices, such as the CyberKnife Robotic Radiosurgery System, offer patients a new option for the treatment of lung cancer. The CyberKnife® System is used to treat lung cancer patients who cannot tolerate surgery, have an inoperable tumor, or are seeking an alternative to surgery.

Our General Surgery team treats hernia patients on a daily basis. In fact, you could consider them to be hernia experts. We sat down with one of those experts, Dr. Heater Dunlap, to talk about the common signs and symptoms of hernias and to answer the question of when to see a doctor.

An excellent video demonstrating how a laparoscopy is performed to evaluate the uterus (note a small fibroid appearing as a bulge in the uterus), fallopian tubes and ovaries. Blue dye is injected into the uterus, entering the fallopian tubes and spilling from the end of the tubes into the abdominal cavity, confirming that both tubes are open

Symptoms of serotonin syndrome include a classic triad of mental status changes (eg, anxiety, delirium, confusion, restlessness), autonomic dysregulation (eg, diaphoresis, tachycardia, hypertension, hyperthermia, diarrhea, mydriasis), and neuromuscular hyperactivity (eg, hyperreflexia, tremor, rigidity, myoclonus, ocular clonus). Serotonin syndrome is clinically diagnosed and laboratory tests are used to rule out other etiologies. It usually occurs due to inadvertent interactions between drugs, therapeutic use of multiple serotonergic agents, or serotonergic medication overdose. Treatment involves discontinuation of serotonergic drugs, supportive measures, and sedation with benzodiazepines. In severe cases, a serotonin antagonist (cyproheptadine) may be used.

lesions at the anterior skull base invading the paranasal area and the paracavernous area can be reached without brain retraction by the shown subfrontal approach. it enables to control the paranasal sinus, optic nerve, periorbital tissue, carotid artery and pituary gland. reconstruction is not easy... but cosmetically appealing. CSF leaks are rare with the use of fascia lata and tissucol ( fibrin glue). osseous reconstruction is done by microsrews and calciumpyrophosphate ( norian, synthes).
