Pityriasis Versicolor: why you get pigmentation spots on holiday - Stylist Magazine

"As it is a very superficial skin infection, it usually settles quickly with treatment, but it is fairly common to have recurrences, especially if the conditions are right. In these situations, we can recommend prophylactic (preventative) treatment with antifungal treatments. Pityriasis versicolor eventually settles down, presumably as our environment or sebum production changes.

"There are no reliable investigations to detect malassezia infection as it's very difficult to grow in the laboratory, so the diagnosis is usually clinical. Occasionally a skin biopsy can be done to exclude other skin conditions," advises Dr Gulati.

Effect of a board game on imprisoned women's knowledge about ... - BMC Public Health

Image
The Previna board game was designed to be a complementary tool in the teaching and learning process about STIs for imprisoned women. The results showed that this educational technology significantly increased the players' knowledge about STIs and that this increase in knowledge remained significant during follow-up. This suggests that there was knowledge retention in the period researched. The increase in knowledge was also present in other studies that used board games for educational purposes [13,14,15,16]. The knowledge retention observed in this study is a result that draws attention, as the school teachers frequently mentioned that the women had difficulty retaining the contents taught in the classroom.

Regardless of...

The 5 Best OTC Cold Sore Treatments of 2024 - Health.com

Image
Cold sores are quite common, and many people have a cold sore outbreak a few times a year. Itchy, painful, irritated, and sensitive cold sores are caused by the herpes simplex virus type 1 (HSV-1) and, less commonly, HSV 2. According to the World Health Organization, an estimated 3.7 billion people globally have an HSV-1 infection at a given time, which is the main cause of cold sores. Most cold sores go away within a few weeks without treatment. However, multiple over-the-counter (OTC) ways to treat cold sores can help speed healing without needing to see a healthcare provider. Many people use oral treatments for prevention or treatment, explains Allison K. Truong, MD, a board-certified dermatologist in Beverly Hills, CA. These can reduce symptoms to seven days or prevent the cold sore from forming if you catch it early enough. We surveyed 28 participants to find out which OTC cold sore treatment they tried, how effective it was, and why they liked it. The below over-the-c...
