Revista de enfermeria (Barcelona, Spain). 2016;(1):49-52
Abstract
INTRODUCTION Epithelitis is a frequent side effect in radiotherapy treatments (RT). OBJECTIVE To evaluate the effectiveness of Rosehip Oil (ARM, Repavar®) in the prevention of epithelitis in patients with head and neck cancer (HNC) treated with intensity modulated radiotherapy (IMRT). MATERIAL AND METHODS An interventionist, prospective, exploratory, controlled and open clinical study. Between May and October 2013, 28 patients were included in the study. After signing the informed consent form, the patients were provided with ARM to apply this twice daily from the beginning of the treatment. All of them had a prescribed dose of IMRT ≥ 60 Gy. They were evaluated weekly by nurses on the ward. A photographic monitoring of the skin with a registered grade of epithelitis and with signs of pain or other was carried out. The control group was formed of 34 consecutive patients with HNC treated with IMRT months prior to the study, whose skin treatment had been different products. RESULTS Both groups were comparable (age, sex, region and RT dose). In the study group (ARM), the number of treatments per patient (p = 0.3) and the natural days for treatment per patient (p = 0.38) were less; also, the number of patients who required treatments and who suffered from radiodermitis of III-IV grade, were less. It is probable that the limited specimen size may have influenced in the statistics. CONCLUSIONS The effectiveness of ARM in the prevention of severe epithelitis in patients with HNC treated with RT is, at least, as effective (or more effective) as other and more common skin treatments. A randomized study would be required to confirm these findinas.

Abstract
Menaquinone-7 (MK-7), a member of the vitamin K2 family, performs several functions, all related to its recognised effect on post-translational carboxylation of certain protein-bound glutamate residues. Due to its lipophilic structure MK-7 is soluble in olive oil, so the aim of the present study was to test whether extra-virgin (EV) olive oil enriched with MK-7 significantly increases MK-7 plasma levels and has an effect on osteocalcin and its carboxylation status. Healthy young volunteers (n 12) were administered 20 ml EV olive oil per d for 2 weeks, followed by 2 weeks of the same amount of olive oil enriched with 45 μg and then 90 μg MK-7, with an appropriate washout time in between. Blood was collected and plasma separated in each phase of the study. We found that integration of the diet with EV olive oil alone did not produce any significant variation of MK-7 plasma levels compared with baseline. Supplementation with MK-7-enriched olive oil resulted in a significant and dose-dependent increase in plasma levels. The high dose also significantly increased carboxylated osteocalcin (cOC) and decreased undercarboxylated osteocalcin (ucOC) plasma levels, resulting in a significant increase in the cOC:ucOC ratio. A significant correlation was also found between percentage variation of plasma cOCA:ucOC ratio and increase in plasma MK-7 levels. We conclude that regular consumption of MK-7-enriched olive oil may constitute a valid approach in order to preserve some key biochemical mechanisms controlling bone mineralisation.

Abstract
Only a few studies have analyzed the effects of the potential interaction between the -174G/C polymorphism of IL6 gene and the adherence to the Mediterranean diet (MD) on adiposity indexes. Our aim was to investigate the interplay between the -174G/C polymorphism of the IL6 gene and a Mediterranean-style diet on body weight changes after 3 years of nutritional intervention in a high cardiovascular risk population. A total of 737 participants, aged 55-80 years were assigned to a low-fat diet or to a Mediterranean-style diet group with high intake of virgin olive oil (VOO) or nuts. Anthropometric measurements were taken at baseline and after 3-year follow-up. The -174G/C polymorphism of the IL6 gene was genotyped. Minor allele frequency (C) was 0.39. At baseline, the CC genotype was associated with higher measures of adiposity. After 3 years, a significant interaction (p=0.028) was found between the polymorphism (GG+GC versus CC) and the nutritional intervention: CC subjects following the MD+VOO had the lowest body weight gain. In conclusion, at baseline, CC subjects for the -174G/C polymorphism of IL6 had the highest body weight and BMI. However, after 3 years of nutritional intervention with MD+VOO, these subjects were predicted to have the greatest reduction in body weight.

Journal of alternative and complementary medicine (New York, N.Y.). 2004;(3):431-7
Abstract
OBJECTIVES Two controlled trials of aromatherapy to decrease agitation in persons with dementia have recently produced promising results. However, both studies combined the use of essential oils with massage. Thus, it is unclear if the effect of the aromatherapy intervention was the result of smelling or the cutaneous absorption of the oils. The purpose of this study was to determine whether smelling lavender oil decreases the frequency of agitated behaviors in patients with dementia. DESIGN The study design was within-subjects ABCBA (A = lavender oil, B = thyme oil, C = unscented grapeseed oil): 4 weeks of baseline measurement, 2 weeks for each of the five treatment conditions (10-week total intervention time), and 2 weeks of postintervention measurement. Oil was placed every 3 hours on an absorbent fabric sachet pinned near the collarbone of each participant's shirt. SETTING A long-term care facility specifically for persons with dementia. PARTICIPANTS Seven agitated nursing home residents with advanced dementia. MEASUREMENTS Agitation was assessed every 2 days using a modified Cohen-Mansfield Agitation Inventory. Olfactory functioning was assessed with structured olfactory identification and discrimination tasks, and with qualitative behavioral observation during those tasks. RESULTS Split-middle analyses conducted separately for each patient revealed no treatment effects specific to lavender, no treatment effects nonspecific to pleasant smelling substances, and no treatment effects dependent on order of treatment administration. There were no differences between participants with more and less intact olfactory abilities. CONCLUSION There is significant evidence in the neurologic and neuropsychologic literature that persons with dementia have impaired olfactory abilities. Concordant with this literature, this study found no support for the use of a purely olfactory form of aromatherapy to decrease agitation in severely demented patients. Cutaneous application of the essential oil may be necessary to achieve the effects reported in previous controlled studies.

Al-Waili, NS
Complementary therapies in medicine. 2003;(4):226-34
Abstract
OBJECTIVES To investigate the effects of honey, olive oil and beeswax mixture on patients with atopic dermatitis (AD) or psoriasis vulgaris (PV). MATERIALS AND METHODS Twenty-one patients with dermatitis and 18 patients with psoriasis were entered for patient-blinded, partially controlled study; 11 patients with dermatitis used topical betamethasone esters and 10 patients with psoriasis used clobetasol propionate. Honey mixture contained honey, beeswax and olive oil (1:1:1). Mixtures A, B, and C contained honey mixture with the corticosteroids ointment in a ratio of 1:1, 2:1, and 3:1 respectively. Patients with dermatitis were subjected to controlled bilateral half-body comparison to evaluate the efficacy of honey mixture against Vaseline, or mixture A against Vaseline-betamethasone esters mixture (1:1) in patients using topical corticosteroid treatment. In patients with psoriasis, the effect of honey mixture was compared with paraffin in an individual right/left-sites comparison, or mixture A against paraffin-clobetasol propionate mixture (1:1) in patients using corticosteroid topical therapy. In dermatitis, body lesions on right or left half-body were assessed for erythema, scaling, lichenification, excoriation, indurations, oozing and itching on a 0-4 points scale. In psoriasis, lesions of selected site were assessed for redness, scaling, thickening and itching, on a 0-4 points scale. RESULTS In honey mixture group, 8/10 patients with dermatitis showed significant improvement after 2 weeks, and 5/11 patients pretreated with betamethasone esters showed no deterioration upon 75% reduction of corticosteroid doses with use of mixture C. In psoriasis, 5/8 patients showed a significant response to honey mixture. In patients using clobetasol propionate, 5/10 patients showed no deterioration upon 75% reduction of corticosteroid doses with use of mixture C. CONCLUSION Honey mixture appears useful in the management of dermatitis and psoriasis vulgaris.

Micklefield, GH, Greving, I, May, B
Phytotherapy research : PTR. 2000;(1):20-3
Abstract
The effect of enteric-coated (Enteroplant) and non-enteric-coated preparations containing a peppermint-caraway oil combination with 90 mg peppermint oil and 50 mg caraway oil was studied on gastroduodenal motility with stationary manometry in six healthy volunteers. The results showed that: (1) both enteric-coated and non-enteric-coated preparations have effects on the migrating motor complex (MMC); (2) mainly a decrease in the number of contractions and contraction amplitudes is seen during the various phases of the MMC; (3) non-enteric-coated preparations have their effects mainly during the first MMC after administration; (4) enteric-coated preparations have their effects temporally delayed during the second MMC after administration. In conclusion, enteric-coated and non-enteric-coated peppermint-caraway oil combinations are safe preparations, acting locally to cause smooth muscle relaxation.
