Study indicates risk for acne may be linked with X chromosome.
(3/27, Wilkinson) reported that, according to a study published in the Journal of Investigative Dermatology, "the risk for acne may be linked with the X chromosome." For the study, researchers from the Dessau Medical Center in Germany examined "risk factors for acne vulgaris among 1,002 Iranian pupils in Tehran, of whom 499 were boys and 503 were girls. The mean age of participants in the cross-sectional study was 16 years." The team found that the "risk for suffering moderate-to-severe acne increased with the number of affected immediate members of the family." Notably, "the mother's acne history was more important in determining its severity than the father's," with both being "more influential in determining acne severity than brothers or sisters." The authors also found that "moderate-to-severe acne was...associated with the premenstrual phase, mental stress, and eating sweet and oily foods, but not with gender, spicy foods, or smoking overall."

Study implicates sunburn, family history in rosacea.
(3/10, McKeever) reported that, according to a study presented at the annual meeting of the American Academy of Dermatology, "people with the reddening skin condition rosacea tend to have a family history of the disease and a personal history of sunburns." Researchers from Harvard Medical School found that, in a "study of 130 people, half with moderate to severe rosacea and half without, 34 percent of those with the disease reported having a relative who also had the skin disorder, whereas only about 10 percent of those without the disease had it in their family." In addition, the team "found that 44 percent of people with rosacea reported having had blistering sunburns at some time, compared with just more than five percent of the others." The authors recommended that "people who have a family history of rosacea," particularly "children...regularly use broad-spectrum sunscreen and use other sun protection measures."

Excimer laser seen as effective treatment for small areas of psoriasis.
In the
(3/17, D6) Aches & Claims column, Laura Johannes observed that the "excimer laser, best known for its use in eye surgery, is now being used to treat psoriasis," and "is extremely effective for small areas affected by the skin disease -- such as a knee or elbow." The device uses "an ultraviolet light wavelength...and a handheld wand that allows the energy to be delivered precisely to the affected areas." Because "small areas are usually involved, more intense light can be used to effectively treat the areas with twice-a-week visits for only five weeks." The painless procedure, which is "typically performed in a dermatologist's office," usually "takes three to five minutes," and "costs $160 or more per visit." A "124-patient
...published in the Journal of the American Academy of Dermatology," found that "84 percent" of patients who completed the study "showed at least a 75 percent improvement on a scale of psoriasis severity in 10 or fewer treatments."

Low-dose acitretin therapy may reduce nail psoriasis, research suggests.
(3/17, Preidt) reported that, according to a
published in the March issue of the Archives of Dermatology, "low-dose treatment with" acitretin, "a drug used to treat skin psoriasis, seems to help reduce nail psoriasis." For the study, researchers from Italy's University of Bologna "evaluated the effect of low-dose acitretin therapy (0.2 to 0.3 milligrams per kilogram per day for six months) on the nails of 27 men and nine women...with nail psoriasis." The team followed patients "for at least six months after treatment," and used "the Nail Psoriasis Severity Index...to grade the severity of their condition." After six months, "clinical evaluation" revealed "complete or almost complete clearing of the nail lesions in nine patients (25 percent), moderate improvement in nine (25 percent), mild improvement in 12 (33 percent), and no improvement in six (11 percent)."

Research suggests 42 percent rise in UK eczema diagnoses between 2001 and 2005.
(3/23, Wilkinson) reports that, according to a
published in the Journal of the Royal Society of Medicine, "there was a 42 percent rise in" eczema diagnoses in the UK "between 2001 and 2005, by which time it was estimated to effect 5.7 million adults and children." For the study, researchers from the University of Edinburgh analyzed the primary-care "records of over nine million patients." The team found that "by 2005, one in nine of the population had, at some point, been affected by eczema," with the "highest rate" being found "in boys aged between five and nine." In addition, prescriptions to treat the condition "increased by 57 percent over the five-year study period." The authors theorized that "eczema is a herald condition for individuals to go on to develop other allergic conditions, such as asthma and allergic rhinitis," and attributed the rise in diagnoses partly to "environmental factors," such as "bathing, and use of soaps and detergents."

New skin disorder may be linked to gaming consoles, researchers say.
(2/24) reported that "skin specialists" in Switzerland have identified a "new skin disorder caused by use of games consoles." In their paper appearing in the British Journal of Dermatology, investigators "outline the case of a 12-year-old girl who attended a Swiss hospital with intensely painful sores on the palms of her hands."

(2/24) explained, "idiopathic eccrine hidradenitis," a skin disorder that produces red, sore lumps on the palms of the hands and soles of the feet," is "seen on the feet of children taking part in vigorous physical activity, such as jogging, and it is thought to be linked to intense sweating." So, initially, "doctors were puzzled" because the girl in question "had not been taking part in any sport or physical exercise." Her parents, however, "recalled that a few days before the sores appeared, she had started using her PlayStation gaming console for several hours a day."
This led investigators to suspect "that tight and continuous grasping of the console's controls together with repeated pushing of the buttons caused the injuries to the girl's hands," the UK

(2/24, Smith) reported that lead author Behrooz Kasraee pointed out that while "most of the symptoms of this type of" video game "'addiction' are considered to be psychological...recently organic pathologies such as acute tendonitis, called Wiiitis, or video game-induced knuckle pads have been added to the list of video game-related pathologies." Now, their study adds one more to the list -- "PlayStation palmar hidradenitis."
