The Effect of Whey Protein Supplements on Acne Vulgaris among Male Adolescents and Young Adults: A Case-Control Study from North of Jordan.

Background: Young people and athletes willing to gain muscle mass and strength are likely to consume whey protein supplements. The effect of milk as a dietary source of whey protein on acne is still controversial. At the same time, a few studies have suggested an acnegenic impact of whey protein supplements. Objectives: To examine the association of whey protein supplements on acne risk among male adolescents and young adults. Materials and Methods: 201 male teenagers and young adults attending fitness centers in Irbid/Jordan were involved in an observational case-control research; those with acne were deemed cases, and those without acne were considered controls. The primary outcome was a comparison of the proportion of participants in each group who consumed whey protein supplements within the previous three months. Results: 100 acne-afflicted participants were compared to 101 healthy controls with similar demographics, including age, body mass index, educational level, and smoking habits, as well as intake of vitamin B12, corticosteroids, and anabolic steroids. However, considerably more participants in the acne group (47%) were taking whey protein supplements than in the control group (27.7%) (p=0.0047). The significance of this difference was maintained after multivariate analysis. Conclusion: This case-control study provides evidence of a positive association between whey protein consumption and acne risk.

Comparison of the efficacy of tacrolimus 0.1% ointment vs calcipotriol/betamethasone in combination with NBUVB in treatment of vitiligo.

Purpose: Vitiligo is an idiopathic depigmenting skin disorder. The study compares the efficacy of topical tacrolimus 0.1% with calcipotriol/betamethasone dipropionate in vitiligo patients receiving NB-UVB treatment.Materials and methods: Forty-one adult patients with generalized type vitiligo were recruited. Patients were assigned to phototherapy and then classified into either group one (20 patients), receiving calcipotriol/betamethasone dipropionate cream (D group), or group two (21 patients), receiving tacrolimus 0.1% ointment (T group). They were followed-up at 3 and 6 months.Results: The D group witnessed an increase in the repigmentation area from 35.4% in the third month to 54.7% in the sixth month (p = 0.001) and the T group from 32.2% to 45.6% (p = 0.011). However, the differences between the treatment groups were not statistically significant. Body sites demonstrated different levels of improvement ranging from the highest in the face to the lowest in the Hand & Feet with the other body sites in between. A negative correlation was identified between the duration since diagnosis and the response to D treatment (3 months: r = -0.612, p = 0.007; 6 months: r = -0.755, p = 0.001).Conclusions: Although both combinations are efficacious, they did not significantly differ in efficacy at three and six months follow-up points.Clinical trial registration: The study was registered at clinicaltrials.gov (NCT04440371).

Using cold air for reducing needle-injection pain.

BACKGROUND: Pain is associated with skin injections. Reducing injection-associated pain is important especially when multiple injections are needed in difficult areas, such as the palms. We present a new safe application for cold air used in laser therapy. OBJECTIVE: The main objectives of this study are to see whether cold air can reduce needle-injection pain and to evaluate the safety of this new application. MATERIALS AND METHODS: Patients undergoing skin injection (n=40) were included. Assessment of pain level using visual analog scale (VAS) was done using cold air and again without cold air in the same patient. Comparison of pain scores was performed. RESULTS: Thirty-three patients had lower VAS scores using cold air. Five patients had worse VAS scores, and two patients did not have any change in their pain score. In the group of patients where injections were made to the palms (n=5), there was even more reduction in VAS scores. There were no significant immediate or delayed side effects. CONCLUSIONS: Cold air seems to be useful in reducing needle-injection pain in the majority of patients, especially in the palms. This procedure is safe, apart from immediate tolerable discomfort when used around the nose.
