Women have long strived to possess long, thick, and dark eyelashes. Prominent eyes and eyelashes are often considered a sign of beauty and can be associated with increased levels of attractiveness, confidence, and well-being. Numerous options may improve the appearance of eyelashes. Mascara aims to temporarily darken, lengthen, and thicken eyelashes using a combination of waxes, pigments, and resins. Artificial eyelashes can be adhered either to the dermal margin or to individual eyelashes. Individuals may even use eyelash transplantations to improve the appearance of their eyelashes. The unique properties of eyelashes (e.g., relatively long telogen and short anagen phases compared with scalp hairs, slow rate of growth, and a lack of influence by androgens) may allow for specific aesthetic interventions to improve the appearance of natural eyelashes. Some over-the-counter (OTC) products may contain prostaglandin analogs that can affect eyelash growth, but neither the safety nor efficacy of these OTC cosmetics has been fully studied. Originally indicated for the reduction of intraocular pressure, the synthetic prostaglandin analog bimatoprost was recently approved for the treatment of hypotrichosis of the eyelashes. In a double-blinded, randomized, vehicle-controlled trial, bimatoprost safely and effectively grew natural eyelashes, making them longer, thicker, and darker. Bimatoprost was generally safe and well tolerated and appears to provide an additional option for individuals looking to improve the appearance of their eyelashes.

Madarosis is a terminology that refers to loss of eyebrows or eyelashes. This clinical sign occurs in various diseases ranging from local dermatological disorders to complex systemic diseases. Madarosis can be scarring or non-scarring depending upon the etiology. Appropriate diagnosis is essential for management. Follicular unit transplantation has been found to be a useful method of treating scarring madarosis and the procedure relevant to eyebrow and eyelash reconstruction has been discussed. A useful clinical approach to madarosis has also been included for bedside diagnosis. The literature search was conducted with Pubmed, Medline, and Google scholar using the keywords madarosis, eyebrow loss, and eyelash loss for articles from 1960 to September 2011. Relevant material was also searched in textbooks and used wherever appropriate.

Cost-effectiveness of Self-management Methods for the Treatment of Chronic Pain in an Aging Adult Population: A Systematic Review of the Literature.
*Health Economics Research Unit, University of Aberdeen, Aberdeen †School of Health, Community and Education Studies, University of Northumbria, Newcastle ‡Health and Social Care Institute, Teesside University, Tees Valley §Centre of Academic Primary Care, University of Aberdeen, Aberdeen ∥School of Medicine, University of Dundee, Dundee, UK.
OBJECTIVE:: To determine the cost-effectiveness of self-management techniques for older populations (65 and over) with chronic pain and in the absence of such evidence to investigate this question in an aging adult population (average age 60 and over). METHODS:: Systematic review of randomized controlled trials (RCTs) with cost-effectiveness data and at least 6 months' follow-up, up to December 2010. RESULTS:: No RCT studies reported cost-effectiveness of self-management exclusively in the over 65 age group. Ten RCTs reported participants with an average age of 60 years or over and met all other inclusion criteria. All of these studies measured cost-effectiveness as cost per improvement in primary outcome, 7 of them using the Western Ontario and McMaster Universities Osteoarthritis Index score, of which 6 reported the pain dimension. Six studies reported cost per quality-adjusted life year (QALY)-gained information, with a further 1 reporting EQ-5D. In 7 studies, relative to usual care, self-management was effective, and in the remaining 3 studies, there was no significant difference. Among those reporting cost per QALY-gained results, self-management did not lead to statistically significant QALY gains relative to usual care (with only one exception). Eight studies suggested that the cost of developing and delivering self-management interventions may be partly offset by savings from reduced subsequent health care resource use. CONCLUSIONS:: Self-management is effective among an aging adult population (mean age over 60) with chronic pain and may be cost-effective when outcomes are measured using the Western Ontario and McMaster Universities Osteoarthritis Index pain score. Cost-effectiveness is less certain when measured using the QALY metric. Uncertainty over conclusions regarding cost-effectiveness exists partly due to lack of information regarding societal willingness to pay for pain improvement. There is a need for large multicentred high-quality RCTs to confirm the findings of this review exclusively among older aged populations, such as those who have already reached the statutory retirement age.

BACKGROUND Sagging of the neck aesthetic area is an important indicator of age. The development of complex and globally accepted tools for proper assessment of the change in neck volume is an essential contribution to aesthetic research and the routine clinical setting. OBJECTIVE To develop a grading scale for the objective assessment of the neck volume and to establish the reliability of this scale for clinical research and practice. MATERIALS AND METHODS A 5-point rating scale was developed to assess neck volume objectively. Twelve experts rated frontal and lateral neck photographs of 50 subjects in two separate rating cycles using the neck volume scale. Responses of raters were analyzed to assess inter- and intrarater reliability. RESULTS Interrater reliability for the neck volume scale was almost perfect, with intraclass correlation coefficients for the first and second rating cycles of 0.85 and 0.84, respectively. Intrarater reliability for the neck volume scale was high (0.90) and Pearson correlation coefficients ranged between 0.88 and 0.95 and were statistically significant. CONCLUSION The neck volume scale demonstrates optimal reliability for clinical research and practice.

BACKGROUND Aging in the lower face leads to lines, wrinkles, depression of the corners of the mouth, and changes in lip volume and lip shape, with increased sagging of the skin of the jawline. Refined, easy-to-use, validated, objective standards assessing the severity of these changes are required in clinical research and practice. OBJECTIVE To establish the reliability of eight lower face scales assessing nasolabial folds, marionette lines, upper and lower lip fullness, lip wrinkles (at rest and dynamic), the oral commissure and jawline, aesthetic areas, and the lower face unit. METHODS AND MATERIALS Four 5-point rating scales were developed to objectively assess upper and lower lip wrinkles, oral commissures, and the jawline. Twelve experts rated identical lower face photographs of 50 subjects in two separate rating cycles using eight 5-point scales. Inter- and intrarater reliability of responses was assessed. RESULTS Interrater reliability was substantial or almost perfect for all lower face scales, aesthetic areas, and the lower face unit. Intrarater reliability was high for all scales, areas and the lower face unit. CONCLUSION Our rating scales are reliable tools for valid and reproducible assessment of the aging process in lower face areas.

BACKGROUND The improvement of aesthetic treatment options for age-related mid face changes, such as volume loss, and the increase in patient expectations necessitates the development of more-complex and globally accepted assessment tools. OBJECTIVE To develop three grading scales for objective assessment of the infraorbital hollow and upper and lower cheek fullness and to establish the reliability of these scales for clinical research and practice. METHODS AND MATERIALS Three 5-point rating scales were developed to assess infraorbital hollow and upper and lower cheek fullness objectively. Twelve experts rated identical mid face photographs of 50 subjects in two separate rating cycles using the mid face scales. Test responses of raters were analyzed to assess intra- and interrater reliability. RESULTS Interrater reliability was substantial for the infraorbital hollow, upper cheek fullness, and lower cheek fullness scales. Intrarater reliability was high for all three scales. Both of the cheek fullness scales yielded higher reliabilities when three rather than two views were used to assess the volume changes of the cheek. CONCLUSION The mid face scales are reliable tools for valid and reproducible assessment of age-related mid face changes.

BACKGROUND Age-related upper face changes such as wrinkles, lines, volume loss, and anatomic alterations may affect quality of life and psychological well-being. The development of globally accepted tools to assess these changes objectively is an essential contribution to aesthetic research and routine clinical medicine. OBJECTIVE To establish the reliability of several upper face scales for clinical research and practice: forehead lines, glabellar lines, crow's feet (at rest and dynamic expression), sex-specific brow positioning, and summary scores of forehead and crow's feet areas and of the entire upper face unit. METHODS AND MATERIALS Four 5-point photonumerical rating scales were developed to assess glabellar lines and sex-specific brow positioning. Twelve experts rated identical upper face photographs of 50 subjects in two separate rating cycles using all eight scales. Responses of raters were analyzed to assess intra- and interrater reliability. RESULTS Interrater reliability was substantial for all upper face scales, aesthetic areas, and the upper face score except for the brow positioning scales. Intrarater reliability was high for all scales and resulting scores. CONCLUSION Except for brow positioning, the upper face rating scales are reliable tools for valid and reproducible assessment of the aging process.

BACKGROUND Twenty grading scales have been developed to assess age-related facial changes. Until now, the validity with regard to the patient's actual age and the clinical importance of combined measurement tools to describe facial aging was unclear. OBJECTIVE To investigate the reliability and validity of a total face score and three global face assessment scales for estimated age, estimated aesthetic treatment effort, and signs of aging in the facial units. MATERIALS AND METHODS Descriptive, reliability, correlation, and principal component analyses based on the assessment of 50 subjects by 12 raters using the 20 grading scales and the global face assessment scales. RESULTS Inter- and intrarater reliability was high for the total face score and for the scales on estimated age and aesthetic treatment effort. Actual age was highly correlated with these three measures. Facial aging was indicated particularly by scales of the lower face. CONCLUSION The aesthetic grading scales and global scales on estimated age and aesthetic treatment effort are reliable and valid instruments. The results suggest that a more-comprehensive evaluation of the human face and its age-related changes can help to identify important areas of facial aging and to define optimal aesthetic treatment strategies.

Involvement of parents in their children's pain management is universally accepted as best practice, yet there is little understanding of their needs. Twelve parents of children with chronic pain were recruited to this study in which the impact of caring for a child with chronic pain was explored. All parents started in distress, and most moved into a stance that enabled them to balance the child's needs with their own. These parents discussed "stepping back" from their child's distress and gaining mastery over fearful emotional reactions. A minority remained in distress, finding an adaptive response to the child's pain challenging. Catastrophic thinking, fear of pain, and the desire to fulfill a nurturing parental role led parents to place themselves continually "on call." Findings indicate that parents might require support to care effectively for their children, and that many of the actions necessitated by children's pain require complex and counterintuitive decisions.
Empty Level Structure and Dissociative Electron Attachment Cross Sections in Bromo and Chloro Dihaloalkanes.
Dipartimento di Chimica "G. Ciamician", Universita di Bologna, via Selmi 2, 40126 Bologna, Italy, Centro Interdipartimentale di Ricerca in Scienze Ambientali (CIRSA), via S. Alberto 163, 48123 Ravenna, Italy, and ISOF, Istituto per la Sintesi Organica e la Fotoreattivita, C.N.R., via Gobetti 101, 40129, Bologna, Italy.
The energies of electron attachment associated with temporary occupation of the C-Br and/or C-Cl virtual sigma* orbitals of dichloro, bromochloro, and dibromo alkanes are measured in the gas phase with electron transmission spectroscopy (ETS). The corresponding orbital energies of the neutral molecules, supplied by HF/6-31G(d)//MP2/6-31G(d) calculations and scaled using an empirically calibrated linear equation, are compared with the experimental vertical attachment energies (VAEs). The largest energy splittings between the first two sigma* anion states are found in the methane derivatives, but two distinct resonances are also observed in the bromochloro and dibromo ethane derivatives. The temporary anions observed in ETS may dissociate, producing Br(-) and Cl(-) negative fragments with widely varying cross sections over the dihaloalkanes studied. The absolute total dissociative electron attachment (DEA) cross sections are evaluated, and their peak values are compared with the corresponding VAEs. In the mixed bromochloro alkanes, the relative intensities of the Br(-) and Cl(-) anion currents detected with a mass filter are also evaluated.

Hair loss is a common problem for both men and women and may impact negatively on self-esteem. A variety of medical and surgical treatment options are available depending on the type of alopecia. Many patients also seek the advice of their physicians about options to hide or reduce the appearance of hair loss with hair prostheses (wigs, hairpieces, and extensions) or hair camouflaging agents (hair fibers, powder cakes, lotions, sprays, hair crayons, and scalp tattooing). Herein, we review current methods to hide or reduce the appearance of hair loss and discuss their associated costs, advantages, and disadvantages. Knowledge of products available to cover scalp, eyebrow, and eyelash hair loss may not only better equip clinicians to respond to questions from concerned patients, but may provide additional options to help these patients best cope with their hair loss.

BACKGROUND Many of today's treatments associated with 'thinning hair', such as female pattern hair loss and telogen effluvium, are focused on two of the key aspects of the condition. Over-the-counter or prescription medications are often focused on improving scalp hair density while high-quality cosmetic products work to prevent further hair damage and minimize mid-fibre breakage. Fibre diameter is another key contributor to thinning hair, but it is less often the focus of medical or cosmetic treatments. OBJECTIVES To examine the ability of a novel leave-on technology combination [caffeine, niacinamide, panthenol, dimethicone and an acrylate polymer (CNPDA)] to affect the diameter and behaviour of individual terminal scalp hair fibres as a new approach to counteract decreasing fibre diameters. METHODS Testing methodology included fibre diameter measures via laser scan micrometer, assessment of fibre mechanical and behavioural properties via tensile break stress and torsion pendulum testing, and mechanistic studies including cryoscanning electron microscopy and autoradiographic analysis. RESULTS CNPDA significantly increased the diameter of individual, existing terminal scalp hair fibres by 2-5 μm, which yields an increase in the cross-sectional area of approximately 10%. Beyond the diameter increase, the CNPDA-thickened fibres demonstrated the altered mechanical properties characteristic of thicker fibres: increased suppleness/pliability (decreased shear modulus) and better ability to withstand force without breaking (increased break stress). CONCLUSIONS Although cosmetic treatments will not reverse the condition, this new approach may help to mitigate the effects of thinning hair.

Clinical utility and differential effects of prostaglandin analogs in the management of raised intraocular pressure and ocular hypertension.
Manchester Royal Eye Hospital, Manchester, UK;
Prostaglandin analogs (PGA) are powerful topical ocular hypotensive agents available for the treatment of elevated intraocular pressure (IOP). Latanoprost 0.005% and travoprost 0.004% are prodrugs and analogs of prostaglandin F2alpha. Bimatoprost 0.03% is regarded as a prostamide, and debate continues as to whether it is a prodrug. The free acids of all 3 PGAs reduce IOP by enhancing uveoscleral and trabecular outflow via direct effects on ciliary muscle relaxation and remodeling of extracellular matrix. The vast majority of clinical trials demonstrate IOP-lowering superiority of latanoprost, bimatoprost and travoprost compared with timolol 0.5%, brimonidine 0.2%, or dorzolamide 2% monotherapy. Bimatoprost appears to be more efficacious in IOP-lowering compared with latanoprost, with weighted mean difference in IOP reduction documented in one meta-analysis of 2.59% to 5.60% from 1- to 6-months study duration. PGAs reduce IOP further when used as adjunctive therapy. Fixed combinations of latanoprost, bimatoprost or travoprost formulated with timolol 0.5% and administered once daily are superior to monotherapy of its constituent parts. PGA have near absence of systemic side effects, although do have other commonly encountered ocular adverse effects. The adverse effects of PGA, and also those found more frequently with bimatoprost use include ocular hyperemia, eyelash growth, and peri-ocular pigmentary changes. Iris pigmentary change is unique to PGA treatment. Once daily administration and near absence of systemic side effects enhances tolerance and compliance. PGAs are often prescribed as first-line treatment for ocular hypertension and open-angle glaucoma.

Eyelashes hypotrichosis is a condition indicated by an inadequate amount of eyelashes. Hypertrichosis of eyelashes, characterized by excessive eyelash growth, is a regular phenomenon associated with ophthalmic prostaglandin and prostamide analogs. Recently, the US Food and Drug Administration approved Latisse((R))(bimatoprost 0.03% solution), identical to the ophthalmic solution for glaucoma treatment, for increasing eyelash length, thickness and darkness in patients with hypotrichosis of the eyelashes. When prostaglandin and prostamide analogs interact with the prostanoid receptors in the hair follicle, this most likely stimulates the resting follicles (telogen phase) to growing follicles (anagen phase). Prostaglandin and prostamide analogs may also prolong the anagen phase of eyelashes, leading to an increase of eyelash length. Although bimatoprost is effective in promoting increased growth of healthy eyelashes and adnexal hairs, its effectiveness in patients with eyelash alopecia areata is debatable and its protective effect is not yet studied in patients with eyelash loss secondary to radiation or chemotherapy. Bimatoprost is generally safe when applied to the base of the eyelashes at the lid margin with minimum side effects. However, other ocular or systemic side effects associated with ophthalmic prostaglandin and prostamide analogs may occur when instilled on the surface of the eye, and patients must be informed and monitored.

BACKGROUND Ocularly applied bimatoprost 0.03% is associated with increased eyelash growth. OBJECTIVE To assess the safety, efficacy, and subjective experience of using dermal application of bimatoprost 0.03% for the growth of natural eyelashes. METHODS Prospective, open-label study of subjects who desired longer, thicker (fuller), and darker natural eyelashes. Bimatoprost was applied to the upper lid margin once daily for 12 weeks. Adverse events and intraocular pressure were assessed, and subjects completed health outcomes questionnaires. Eyelash growth and darkening were scored using photographs taken at weeks 1 and 12. RESULTS All subjects were female (N=28). No serious or unexpected adverse events were reported. The mean change from baseline intraocular pressure was less than 1 mmHg at each time point, but was statistically significant at weeks 1 and 4 (p</=.047). At week 12, all subjects had noticed significant growth or darkening. Post hoc analysis of photographs corroborated these reports (p<.001). CONCLUSION Bimatoprost was found safe for eyelid application and was associated with enhanced eyelash growth. All subjects noticed favorable changes in the appearance of their eyelashes. This study was funded by an unrestricted investigator-initiated research grant from Allergan, Inc., Irvine, CA. J. Walt is a health outcomes researcher and an employee of Allergan.

BACKGROUND Many women desire prominent eyelashes. In December 2008, bimatoprost ophthalmic solution 0.03% was approved for the treatment of hypotrichosis of the eyelashes in the United States. OBJECTIVE To review eyelash physiology and the proposed mechanisms by which the topical pros-tamide product bimatoprost enhances eyelash growth. METHODS AND MATERIALS Clinical and preclinical studies pertaining to the efficacy, safety, and mechanisms of action of bimatoprost are presented. RESULTS Treatment with bimatoprost increases the percentage of eyelash follicles in anagen at any one time. This probably accounts for its ability to lengthen lashes. Bimatoprost-induced stimulation of melanogenesis appears to result in darker lashes and, at the same time, appears to increase the size of the dermal papilla and hair bulb, affecting lash thickness and fullness. Such effects, largely demonstrated in animal studies, are consistent with the results of a recent Food and Drug Administration phase III clinical trial. The favorable safety profile of bimatoprost in human subjects is probably secondary to the limited exposure of ocular tissues resulting from topical application at the base of the upper lashes. CONCLUSION By influencing the eyelash hair cycle and follicles, bimatoprost ophthalmic solution 0.03% is a safe and effective means of enhancing eyelash growth.

Hirsutism is an excessive body and facial hair growth in women in locations where is normally minimal or absent following a hair-male pattern. For this reason is not uncommon that hirsutism raises psychological, cosmetic and social concerns. There are many treatment modalities that can be summarised into two broad groups: pharmacologic and non-pharmacologic treatment. Until now, medical treatment has been designed to interfere with the synthesis of androgen at the ovarian or adrenal level, or inhibit the effect of androgen at the receptor level, although recent progresses test other options such as insulin modulators or ornithine decarboxylase inhibitors. Mechanical treatment includes laser hair removal, electrolysis, depilatory creams, plucking and waxing. This article presents a general overview of hirsutism treatment options.

OBJECTIVE: To determine whether bimatoprost (Lumigan, Allergan Inc., Irvine, CA) causes increased lash length when used in gel suspension applied to the base of the eyelashes. DESIGN: Randomized controlled trial. PARTICIPANTS: Nineteen subjects were enrolled. METHODS: Subjects recruited from the Bascom Palmer Eye Institute were screened, and those who met inclusion criteria were enrolled. Each participant received 2 vials of gel suspension, which contained bimatoprost and normal saline, respectively, each mixed 1:1 with Gonak gel (Akorn Inc., Lake Forest, IL) and labeled "right eye" and "left eye" according to randomization. The suspension was applied to the upper eyelid eyelashes every evening on the designated eye for 6 weeks. MAIN OUTCOME MEASURES: Lash length was measured with a caliper at enrollment, at weekly intervals during the application of the gel, and at 1 and 3 months after discontinuation of its use. Visual acuity, ocular symptoms, intraocular pressure, and photographs were documented at these same intervals. RESULTS: The mean eyelash growth from baseline in the bimatoprost group was 2.0 mm versus a mean of 1.1 mm in the placebo group, which was a statistically significant difference (P=0.009). The average intraocular pressure decreased equally in both groups (2 mmHg). No change in visual acuity or iris discoloration was noted in any of the subjects. CONCLUSIONS: Our data showed an increase in eyelash length with the use of bimatoprost in gel suspension, suggesting the product's eyelash-lengthening properties.
