Sickle Cell Disease and Cosmetic Surgery

Please tweet and retweet



Hemoglobin is the protein in red blood cells that carries oxygen. It is encoded by 2 genes in one's DNA, 1 gene from each parent. Either or both of these genes can have a sickle cell trait so that the hemoglobin produced by either or both as the case may be is abnormal. If only one gene is abnormal the individual is said to have sickle trait. If both are involved the individual has sickle cell disease. The sickle gene is most commonly found in those of sub-Saharan African descent. It is thought that that is because the sickle trait confers resistance to the malaria that is present there. 0.5% of the Afro-American population has both genes and 8% have the trait. Under low oxygen levels the sickle hemoglobin changes shape and makes the red blood cell it is in turn into a sickle shape. Conditions that make the abnormal cells sickle include lowered body temperature, infections, acidic metabolic conditions, dehydration and as mentioned lowered blood oxygen levels. The sickle shaped blood cells have a shorter life span and tend to get caught in the smaller blood vessels of the body. The manifestation of this depends on the percentage of total body red blood cells/hemoglobin that is abnormal. Those with only the trait (one gene) have an easier time. When the percentage is high it is associated with anemia, stunted growth, sores on the legs, heart problems, shortened life span, organ failure etc.

The effect on cosmetic surgery and the measures needed to ensure safe surgery depend on the percentage. At low percentages you do not need to do anything different from other patients. At higher percentages the patient may need pre-surgery treatment with one or more of the following supplemental oxygen, blood transfusion, over-hydration, folic acid supplementation, vaccinations etc. In some cases the abnormal cells are trapped in the spleen so the peripheral blood tests may only show anemia with immature red blood cells as the bone marrow compensates by ramping up production of red blood cells. The absence of visible peripheral sickle cells in such cases does not mean the patient is a lower risk for surgery. None of these patients should undergo prolonged operations and if necessary surgery should be staged. If the percentage is very high the patient should probably not be having elective cosmetic surgery. If you are prone to sickle cell crises or have sickle cell related skin sores you should not have any cosmetic surgery. Your surgeon needs to work together with a hematologist in order to ensure a smooth recovery after surgery.

Mommy Makeover Abdominoplasty with Pelvic Sling for Urinary Incontinence

Please tweet and retweet



Urinary incontinence (leaking of urine) can be problematic and embarrassing for women past their childbearing years. Pregnancy and/or the aging process weakens or damages nerves, muscles and/or their supporting structures in the pelvic area. This results in incontinence (inability to hold back urination). There are different types such as stress incontinence, urgency incontinence etc. After trials of non-surgical treatments such as injection of bulking agents around the urethra (tube extending down from the bladder that urine flows through) have failed sling or bladder neck suspension surgical procedures may be needed to treat stress incontinence.
