Have summer fun guys … but avoid those fungi!

Summer is fast approaching which for many means fun in the sun, swimming pools, increased gym time to get beach ready…. and an increased risk of acquiring the dreaded “athlete’s foot”. Not just a problem for athletes, “athlete’s foot” is actually caused by a fungus that invades and proliferates in the skin. It can spread to the hair and nails but does not spread internally. Signs of athlete’s foot include red, scaly patches on the bottom and sides of the foot, cracks between the toes, and sometime small little blisters. Continue reading

What SPF sunscreen should I use?

A fascinating new dermatology study shows sunscreens with SPF 70+ actually provide more protection.  This is because all of us routinely under-apply sunscreen. We are supposed to apply 2 mg/cm2 of sunscreen (approximately 1 oz of sunscreen for the body or a shot glass full). However, the actual protection we Continue reading

My Spicy Food is Making Me Sweat!

Recently, a Desi Dermatology reader posed a question about a problem with increased sweating after eating hot and spicy foods. This is not an uncommon phenomenon and serves as a good launching pad to discuss the issue of excessive sweating or “hyperhidrosis” in general.

Excessive sweating may occur in three patterns:

  • Under the arms and on the palms/soles.
  • Localized sweating isolated to certain body parts such as the scalp or forehead.
  • Generalized sweating diffusely over the body . Continue reading

The Common Culprit: Male Pattern Hair Loss

Hair loss is an extremely common problem in men seeking the care of a dermatologist.  It can occur in men as early as the late teenage years and can therefore be an extremely sensitive issue for many young men. In others, it may become more apparent later in the 20’s or 30’s. There are a number of possible causes of hair loss in men but most hair loss is due to male pattern hair loss or “androgenetic alopecia”. This type of hair loss results from the action of dihydrotestosterone on the hair follicle which causes it to miniaturize and close up. Dihydrotestosterone is a product of the enzyme 5 alpha-reductase acting on testosterone. Continue reading

Dermatologist Mohiba Tareen looks impossibly well rested. For her, that’s the ultimate compliment.

“Let me tell you, I’m not well rested,” she said.

As the mother of two young boys and in the midst of establishing her dermatology practice in Roseville, she credits the carefully placed use of fillers under her eyes and in a tiny acne scar and Botox for her perfectly smooth, yet natural complexion.

Tareen recently relocated from New York, where she worked at a high-end Manhattan practice. In addition to being an adjunct professor at the University of Minnesota’s Medical School and an expert for WebMD.com, Tareen is launching cosmetic services such as Botox and fillers at the Ivy Spa in Minneapolis.

There, she’ll help Minnesotans capture her same impossibly fresh look.

“Small, subtle things make a huge difference,”  she said. “I don’t want somebody to say, ‘What did you have done?’ I want somebody to say, ‘You look well rested.’ ‘You look like you got a great haircut.’ ‘You look like you went on vacation.'”

She shared some of her skin-care advice. Continue reading

The Silent Skin Cancer: Subungual Tumors

My patients are always surprised when I check their fingernails and toenails for skin cancer. “Doc, you can even get skin cancers under your nails?” is the typical question. Indeed, although rare, it is possible to get skin cancers, and even deadly forms of melanoma under the nail.

 Skin cancer under the nail may begin in many ways:

  1. A thin brown line that gets darker and thicker over time: this may indicate a melanoma, and requires immediate attention. Your dermatologist may evaluate for Hutchinson’s sign:  this is pigmentation in the cuticle, the nail fold (the skin on the sides of the nail), or even the lunula (half-moon at the base of the nail). If Hutchinson’s sign is present, a biopsy should be performed urgently.   Continue reading

Let us continue our acne series with the prescription medication Metronidazole (Metro). Metro is both an oral and topical antibiotic.

 

How does Metronidazole work?

Metro is part of a class of antibiotics known as nitroimidazoles. These type of antibiotics cause breakage of DNA – in fact, Metro can be used to treat both bacteria and parasite infections! In addition, topically metro has effective anti-inflammatory and antioxidant and effects – helping reduce redness and aging.
