Biotin, also known as vitamin B7 and nicknamed vitamin H, is present in many multivitamins. The recommended daily dose for adults is around 30 mcg (30 micrograms, which is much smaller than a milligram). However, some supplements promoted for hair, nail, and skin health contain biotin at much higher doses, as much as 10,000 mcg (over 30,000% the recommended daily need).
Consuming large amounts of biotin can be problematic. Some lab analyzers use an immunoassay that contains biotin. In patients with excess biotin in their blood samples, there is an increased risk of false lab values due to the inability of the patient’s blood to bind properly.
There is insufficient data to know if waiting for hours or days before running lab tests would help. Furthermore, waiting is obviously impractical when running critical lab tests such as for a heart attack or pregnancy.
Coronavirus (COVID-19) has changed our world. In the realm of podiatry, two issues were examined.
“COVID toes” is a red discoloration, as if there was a bruise. There may be itching and burning sensation like frostbite. It is not known whether this phenomenon is due to inflammation from coronavirus, an immune response, or increase in blood clotting (or combination thereof). Thankfully, COVID toes heal without a scar and is not seen in most patients.
Although a study from Wuhan, China found coronavirus on shoes, it is unlikely that this is a common way that the virus is transmitted. The virus on shoes would still need to enter the body and may not be viable at that time. The reason this subject became popular may be due to this excerpt from the article: “…the virus can be tracked all over the floor, as indicated by the 100% rate of positivity from the floor in the pharmacy, where there were no patients. Furthermore, half of the samples from the soles of the ICU medical staff shoes tested positive. Therefore, the soles of medical staff shoes might function as carriers.”
Many businesses in Japan require working women to wear high heels. (Airlines in the United States have similar rules.) Yumi Ishikawa, a Japanese actress and freelance writer, feels that’s unfair.
Her efforts to change public policy have been bolstered by a clever hashtag: #KuToo which is a play on the Japanese words kutsu (shoes), kutsuu (pain), and a nod to the #MeToo movement.
High heels have long been seen as a female equivalent to the businessman’s necktie. Others, however, have compared such high-heel policies to foot binding, a practice in ancient China when smaller feet were seen as more desirable.
English actress Nicola Thorp made headlines after going public about being fired from a job as a receptionist for refusing to wear high heels. Shortly thereafter, British Columbia and the Philippines passed laws banning companies from forcing women to wear high heels.
If you have pain from high heel shoes, call (847) 675-3400 to schedule an appointment with Dr. Steven Miller.
