Have you ever lost your sense of smell or taste? Recall how it feels when your face/mouth don’t work properly until the nerve blocks wear off after a dental procedure.
Those are all things (and more) a facial transplant patient has to deal with. The article discussing recovery of sensation after facial transplantation in the May issue of Plastic and Reconstructive Surgery discusses this topic (first reference below).
In addition to reviewing their own face transplant patients (n=4), Dr. Maria Siemionow and colleagues did a literature review (English literature for peer-reviewed articles published between 1940 and 2010) of sensory recovery after various standard nerve repair techniques.
These other nerve repair techniques included repair of the peripheral branches of the trigeminal nerve; sensory return after free tissue transfer (ie noninnervated flaps, including radial forearm, lateral thigh, anterolateral thigh, latissimus dorsi, trapezius, et al and innervated free flaps, including radial forearm, anterolateral thigh, and rectus abdominis musculocutaneous flaps); and sensory recovery following replantation of scalp and forehead.

The Doctors TV show actually produced a great (and accurate) segment on a relatively new procedure called sialendoscopy. This procedure allows a surgeon to remove a stone that may be blocking your spit gland from draining saliva into the mouth. This is analogous to a kidney stone which blocks urine from draining from the kidney into the bladder resulting in painful swelling of the kidney (causing flank pain).
How does a person know if they have a salivary gland blockage due to a stone? There is a painful swelling located right in front and/or below the ear if the parotid gland is affected, or under the jawbone if the submandibular gland is blocked.
If the blockage persists long enough, it may lead to an infection of the gland itself (sialadenitis). Read more »

There is an article (see reference below) in the June 12, 2008 issue of the New England Journal of Medicine (h/t Medpage Today) that shows some amazing regression of hemagiomas using propranolol.
Hemangiomas of infancy are the most common tumor of infancy. They typically appear within a few weeks after birth and peak within three months. Hemagiomas are more common in girls than boys, more common in white than other races, and more common in preemies. Most of these lesions are innocuous and regress without treatment. Up to 75% shrink to insignificance by the time the child reaches school age. However, 5-10% of the lesions that will ulcerate during the rapid growth phase in the first 6 months of life. Ulceration is the most common reason for referral to specialists, and may be associated with pain, bleeding, infection, disfigurement, and scarring.
This one series of photos shows the results:
Panel A shows the patient at 9 weeks of age, before treatment with propranolol, after 4 weeks of receiving systemic corticosteroids (at a dose of 3 mg per kilogram of body weight per day for 2 weeks and at a dose of 5 mg per kilogram per day for 2 weeks).
Panel B shows the patient at 10 weeks of age, 7 days after the initiation of propranolol treatment at a dose of 2 mg per kilogram per day while prednisolone treatment was tapered to 3 mg per kilogram per day. Spontaneous opening of the eye was possible because of a reduction in the size of the subcutaneous component of the hemangioma.
Panel C shows the patient at 6 months of age, while he was still receiving 2 mg of propranolol per kilogram per day. Systemic corticosteroids had been discontinued at 2 months of age. No subcutaneous component of the hemangioma was noted, and the cutaneous component had considerably faded. The child had no visual impairment.
Panel D shows the child at 9 months of age. The hemangioma had continued to improve, and the propranolol treatment was discontinued.
Christine Léauté-Labrèze, M.D., of Bordeaux Children’s Hospital, and colleagues used the drug to treat two infants with heart disease (one with cardiomyopathy, the another with increased cardiac output) who just happened to also have hemangiomas. Unexpectedly, the lesions began to fade. They then used propranolol on nine other children with hemangiomas with similar success.
Johns Hopkins researchers have developed a protocol for the beta-blocker as a first-line treatment for the skin disorder. Propranolol could replace or supplement steroids such as prednisone which are often used currently. The children receive 1 mg/kg of propranolol on the first day, divided over three doses, and 2 mg/kg — also divided in thirds — after that.
Prednisone use carries the side effects of growth retardation, elevated blood sugars, and reduced resistance to infection.
Propranolol has side effects that include hypotension and hypoglycemia, but these are short-lived.
So far, Dr. Cohen and Katherine Puttgen, M.D., also at Johns Hopkins, say they have treated 20 patients with propranolol. Working with cardiologists, they decided to hospitalize the infants for the first two days of treatment to monitor for possible side effects such as hypotension or hypoglycemia. (They have seen none so far.)
Dr. Léauté-Labrèze, and colleagues reported that they are applying for a patent for the use of beta-blockers in infantile capillary hemangiomas.
