Botox Manufacturing Kills Mice

Please tweet and retweet


I just found out today that for every batch of botulinum toxin created, tests are performed on laboratory mice. The test employed is the LD 50, that is the dose of botox that kills 50% of the mice it is given to. After the toxin is administered by a needle stick to the belly impaired vision, paralysis and respiratory arrest follow. Those that die suffocate. The process takes three or four days. The surviving mice are then euthanized. It is estimated that worldwide at least 600,000 mice die in the production of botox each year. In the European Union alone, tens of thousands of animals are estimated to be used in this testing per year. As the use of botox increases so does this number. Europe has a ban on animal testing for cosmetics but botox is considered a medical treatment so the ban does not apply. There currently is no other assay available or in use to determine botox strength and doseage in each batch of botox that is manufactured.

July 26, 2011 addendum:
Allergan (the manufacturer of Botox) spent $65 million on more than a decade of research that led to a new animal-free test, testing the effect of Botox on cells in a lab dish. The Food and Drug Administration approved the test in June 2011. Allergan estimates it will be able to reduce its animal testing by 95 percent over the next three years as countries outside the United States approve the new procedure as a replacement for the old LD50 test.

Baby Ear Deformity - Deformed Baby Ear

Please tweet and retweet


25% to 35% of babies born in the United States each year are born with an ear deformity. That is 1.5 million babies each year. There are 4 types of ear defects:
1-small or absent ears
2-folded ears also called lop ear where the top of the ear is folded downward or Stahl's ear when the top of the ear is pinched like a Star Trek Vulcan look
3-cup or constricted ear which looks like there is an invisible ring around the ear squeezing it
4-protruding ears that stick out from the sides of the head
Some studies have reported that 70% of ear deformities will either worsen or remain the same over time as the child ages.

#Hidradenitis of the Armpits - Boils Under the Armpits

Please tweet and retweet



Inflammation of the armpit glands or #Hidradenitis, was first described by Velpeau in 1839. In 1854, Verneuitt suggested that this condition might arise from the sweat glands of the skin and described the clinical condition which is now recognized as hidradenitis suppuritiva. Since then, hidradenitis surgeons have recommended many forms of treatment for this entity: lotions, vaccines, fever therapy, toxoids, steroids, ultraviolet light, X-rays, antibiotics, and surgery. The disease does not occur before puberty because the apocrine sweat glands do not function at that age. Patients see this as boils under the armpits that swell, drain foul smelling material and then swell again as the cycle starts over again.

Nasojugal crease, tear trough deformity, nasojugal groove, bags under eyes, under eye hollowness

Please tweet and retweet



In the young individual the transition between lower eyelid and cheek is imperceptible. The dividing line between these areas in older individuals is the nasojugal crease also called the nasojugal groove (term first used in 1961) or tear trough (term first used in 1969). It is an early sign of aging around the eyes, lending a fatigued and aged appearance to the face. As part of the aging process ligaments that fix facial skin to the underlying facial bones thin and lengthen or stretch, facial bones recede back and facial fat shrinks. This results in the drooping of facial skin and appearance of laugh lines, jowls, nasojugal creases, eyelid bags etc.. The skin within the nasojugal groove or crease becomes thinner and/or darker in color than the slightly lower nose or cheek skin. It can also seem deeper or be more visible if there is protrusion of fat into the lower eyelid. The aging process starts near the nose as the tear trough and progresses outwardly towards the same side ear becoming what is called the palpebromalar groove.

Gynecomastia

Please tweet and retweet


Gynecomastia means enlargement of the male breast. The definition has nothing to do with what causes the enlargement or what tissue it is composed of. It is most common around puberty & can involve one or both sides of the chest. Most commonly the enlargement is centralized in the breast but occasionally it is not. It is present to some degree in about a third of male population. It appears either early in adolescence or later in the adult years of life and can be very disruptive in the life of a teenager or adult. Working out in the gym, going to the beach and changing in the locker room can become unpleasant ordeals.

Asian Rhinoplasty - AfroAmerican Rhinoplasty

Please tweet and retweet


caucasian asian and black types of nosesThere are 3 main types of noses - Caucasian, Asian or Oriental and African. The Asian nose has characteristics between those of the Caucasian and African. Today one increasingly finds mixed features between these groups as well so some individuals can have a Caucasian tip with an African bridge or vice versa. The most visible difference is the more vertical nostril alignment with a longer strip of skin between the nostrils in the Caucasian nose vs. the Asian or African nose. The Asian and African nasal bridges are flatter and broader than the Caucasian. In some cases the bridge may be so flat that it appears scooped out or ski sloped. The nasal tip skin is usually thicker with a more rounded tip in the Asian and African noses. The thinner nasal tip skin in the Caucasian nose makes the tip cartilages and their shapes more visible on external viewing.

differences between types of noses
As you can see in the above diagram these differences are due to differences in the skin but mostly due to differences in the underlying bone and cartilage. In Asian and African noses:

Even a dog can benefit from a facelift

As you can see even a dog can benefit from a facelift. This Shar pei required a facelift because the extra folds of skin were damaging the dog's eyes.

This Los Angeles billboard was actually an ad for a Comedy Central television show not a Veterinarian or a Plastic Surgeon

Axillary Hyperhydrosis Hyperhidrosis - Excessive Armpit Sweating

Please tweet and retweet



Excessive seating from the armpits can be very debilitating causing a bad odor, staining of clothing and restriction of social as well as exercise related activities. This problem can also affect the palms of the hands or soles of the feet.

Sweat glands maintain skin surface health and regulate body temperature by supplying water to the skin surfaces for evaporation. Two types of sweat glands are present over human skin, eccrine and apocrine glands. Millions of eccrine glands are distributed throughout the entire body surface and produce a high salt content sweat that is excreted directly onto the skin through an excretory duct. The greatest density of these glands is found in the armpit, palm, and sole of the foot. The apocrine sweat glands are less in number and are distributed over the armpits, around the anus, around the breast nipple complex, and eyebrow regions. In addition to salt, the sweat from these glands contains fat and cholesterol and is excreted indirectly by passing through the shaft of hair follicles. The apocrine gland is 10 times larger than the eccrine gland, and both are present in equal numbers in the armpits. The apocrine glands start secreting at puberty and stop after menopause in women. Overproduction of either gland in the presence of certain skin surface bacteria can produce a bad odor. Clogging of the apocrine glands leads to a condition called hydradenitis suppuritiva with abscesses and draining pus. The treatment for this is surgical removal of the glands together with the damaged skin and then surgical closure of the resulting wound.

Asian Upper Eyelid Surgery - Asian Upper Blepharoplasty

Please tweet and retweet



In the caucasian upper eyelid the deeper layers of the eyelid converge 6 to 8mm above the eyelid margin/eyelashes to create a crease (labeled upper lid crease in the diagram above). In the typical asian upper eyelid these layers do not converge so there is no crease. The absence of this convergence allows fat to descend into the eyelid (as noted in the diagram above) giving the puffy look that is seen in some asian eyelids and the no upper eyelid crease appearance.

Breast Implants Augmentation Reconstruction and a Natural Look

Please tweet and retweet



Most of us know when we see a good result from breast surgery whether it be implants for breast augmentation or reconstruction after breast cancer surgery (mastectomy) or the results of a breast reduction surgery. As I described in my blog on facial proportions analysis a similar proportions assessment is used in planning any breast surgery and in assessing the end result.
normal breast proportions
That is to say for the average woman between 5 and 6 feet tall the desired proportions are that the nipples form an equilateral triangle with the upper notch of the breast bone and each side of the triangle is about 20cm in length. Additionally the distance between each nipple and the fold under the breast should be about 7cm with a gentle curve outline along the bottom of each breast. Together with equal sized nipple areola complexes this creates the left right symmetry and aesthetic look we strive for. The question then arises as to how one achieves this goal or result after breast surgery. This blog will only deal with breast implants rather than breast reductions and mostly with options available to correct for deviations from this pattern after breast implant placement i.e. redo breast implant surgery when the nipple is in the correct position.
