Hypercalcemia is a condition in which the calcium level in your blood is above normal. Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with the way your heart and brain works. Hypercalcemia most commonly results from overactive parathyroid glands. These four tiny glands are each about the size of a grain of rice and are located on or near the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and excessive use of calcium and vitamin D supplements. Signs and symptoms of hypercalcemia may range from nonexistent to severe. Treatment depends on the underlying cause.
Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, your heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels open up to improve blood flow. Examples of beta blockers Some beta blockers mainly affect your heart, while others affect both your heart and your blood vessels. Which one is best for you depends on your health and the condition being treated. Examples of oral beta blockers include: Acebutolol (Sectral) Atenolol (Tenormin) Bisoprolol (Zebeta) Metoprolol (Lopressor, Toprol-XL) Nadolol (Corgard) Nebivolol (Bystolic) Propranolol (Inderal LA, InnoPran XL)
Virtual Ports, Ltd. (http://www.virtual-ports.com) is a medical device company developing and marketing instruments to improve minimally invasive laparoscopic procedures.
The EndoGrab retraction system reduces the number of ports needed for surgery by eliminating the need for traditional hand held retraction. For the surgeon, this simple solution results in the need for less auxiliary personnel, a decreased overall surgery cost, and more control over the surgery. The EndoGrab also offers added benefit to the patient who will experience less post-operative discomfort and scarring.
The EndoGrab is an internally anchored, hands-free retracting device that is introduced at the start of surgery through a 5mm trocar by means of a proprietary Applier tool. The Surgeon uses the Applier to attach the EndoGrab to both the organ requiring retraction and to the internal abdominal wall, thereby removing the organ from the operative field. The Applier is then removed and the port is free for use by other instruments.

Sebaceous cysts are common noncancerous cysts of the skin. Cysts are abnormalities in the body that may contain liquid or semiliquid material. Sebaceous cysts are mostly found on the face, neck, or torso. They grow slowly and are not life-threatening, but they may become uncomfortable if they go unchecked. Doctors usually diagnose a cyst with only a physical examination and medical history. In some cases, a cyst will be examined more thoroughly for signs of cancer
Results Sinusitis was characterized as acute in 26 patients, subacute in 5 (including 1 pyocele), and chronic in 8 (including 2 fungal infections). No tumors were found. Isolated sinus cysts were excluded from the study. Headache, the main symptom in 32 patients (82%), was localized most commonly on the vertex. Other common complaints were rhinitis, dizziness, eye symptoms, and fever. In 2 patients, the finding was occult. Eight patients (21%) presented with cranial nerve deficits, and 1 patient had an intracranial complication. Sinus irrigation was performed in 16 patients (41%) and sphenoidotomy was performed in 10 (26%). Fifteen patients (38%) were treated with antibiotic drugs alone. Within 3 months, 31 (84%) of 37 patients had recovered from the illness; 5 still experienced headaches despite having normalized radiographic findings; and 1 had permanent unilateral visual loss. Two patients were lost to follow-up.
