Valisure, an online pharmacy known for testing every batch of medication they sell, announced this week that they petitioned the FDA to recall 40 batches of sunscreens and after-sun products they say tested for high levels of the chemical benzene. The company tested 294 batches from 69 companies and found benzene in 27% ― many in major national brands like Neutrogena and Banana Boat. Some batches contained as much as three times the emergency FDA limit of 2 parts per million (ppm). Long-term exposure to benzene is known to cause cancer in humans.

Boys with obesity have lower testicular volume compared with their normal-weight counterparts, suggesting the potential for fertility problems in adulthood, new data suggest. Testicular volume is a fertility marker directly related to sperm count that has halved in the past 40 years worldwide for unknown reasons. At the same time, childhood obesity has risen dramatically and infertility appears to have risen as well, Rossella Cannarella, MD, of the department of endocrinology and andrology, University of Catania, Italy, said during ENDO 2022: The Endocrine Society Annual Meeting.

What is the role of imaging studies in the diagnosis of paronychia?

@neel Results showed those given combination treatment gained just over half the amount of weight as those given monotherapy. They were also 36% less likely to gain at least 10% of their body weight during the 12-week treatment period. These findings add to those from the earlier ENGLIGHTEN-2 trial, which included patients with a more established disorder, said lead investigator René S. Kahn, MD, PhD, Icahn School of Medicine at Mount Sinai, New York City.

@palash o more accurately forecast global dementia prevalence and produce country-level estimates, the investigators leveraged data from 1999 to 2019 from the Global Burden of Disease (GBD) study, a comprehensive set of estimates of worldwide health trends. These data suggest global dementia cases will increase from 57.4 million (50.4 to 65.1) in 2019 to 152.8 million (130.8 to 175.9) in 2050. Regions that will experience the worst of the increase are eastern Sub-Saharan Africa, North Africa, and the Middle East. The researchers also factored into the forecasts expected trends in obesity, diabetes, smoking, and educational attainment.

@tintin Excessive hair loss in winter is largely due to the dry air outside that sucks out all the moisture from your scalp, and makes it dry. A dry scalp leads to dry hair, which in turn results in hair damage, breakage, and hair loss. A dry scalp also leads to dandruff, which makes your head feel itchy and unhealthy. This, along with arid air, can cause a significant amount of hair fall in the winter.
There’s nothing like a good scalp massage for your hair in the winter. This helps increase blood circulation to your scalp, which helps strengthen the hair follicles from within.
Unhealthy diets coupled with lack of essential vitamins, minerals and other hair nutrients in your diet can result in hair loss. Vitamin A stirs up healthy production of sebum in the scalp, vitamin E stimulates blood circulation in the scalp to help hair follicles remain productive and vitamin B helps in maintaining the hair’s health. Poor diet coupled with nutritional deficiencies inhibits your body’s ability to create new hair follicles.

A 33-year-old previously healthy woman presented with abdominal pain and behavioral symptoms. She developed hyponatremia, seizures, and rapidly progressive weakness leading to respiratory failure, quadriplegia, and autonomic instability. Cerebrospinal fluid was acellular with normal protein and glucose. Initial nerve conduction studies showed prolonged F waves, and follow-up studies demonstrated absent sensory and motor responses with signs of profuse active denervation on needle examination (fibrillation potentials and reduced recruitment). Quantitative urine testing for porphyria was abnormal and in keeping with AIP. The patient had severe axonal porphyric neuropathy resulting in significant disability. What are the management optons?

@patatri Your healthcare provider may prescribe an oral antibiotic to treat mastitis. The infection should clear up within 10 days but may last as long as three weeks. Mastitis sometimes goes away without medical treatment. To reduce pain and inflammation, you can:
Apply warm, moist compresses to the affected breast every few hours or take a warm shower.
Breastfeed every two hours or more often to keep milk flowing through the milk ducts. If needed, use a breast pump to express milk between feedings. Drink plenty of fluids and rest when possible. Massage the area using a gentle circular motion starting at the outside of the affected area and working in toward the nipple. Take over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDS). Wear a supportive bra that doesn’t compress the breast.
