Laser-based photoepilation of dark skin types demands a delicate combination of appropriate light wavelengths and spot size to achieve optimal epidermal-to-follicular energy absorption ratios. This prospective study assessed the axillary, arm, thigh, and back hair clearing ef cacy of the LightSheer In nity 1060 nm diode laser in 10 Fitzpatrick skin type IV-V patients. Each area was treated up to ve times, at 4-6-week intervals, after which immediate skin responses and adverse events were recorded. Hair count, color and coarseness were assessed before each treatment session, as well as 1, 3, and 6 months following the last session...

A robotic system can select and remove individual hair follicles from the donor area with great precision and without fatigue. This report describes the use of the robotic system in a megasession for hair restoration. Patients were instructed to cut their hair to 1.0 to 1.2 mm before surgery. The robot selected and removed 600 to 800 grafts per hour so the follicular units (FU)s could be transplanted manually to recipient sites. The robot arm consists of a sharp inner punch and a blunt outer punch which together separate FUs from the sur- rounding tissue...

INTRODUCTION: Diode lasers are often considered as the gold standard preference for hair removal due to the deep penetration and ef- fective targeting of the hair follicle. A wide variety of diode lasers are available, which can differ in terms of their parameters (such as fluence, pulse duration, repetition rate, scanner, and cooling). OBJECTIVE: The objective of the study was to evaluate the safety and ef cacy of hair removal with an 810 nm novel scanning diode laser, up to six months after last treatment...

In diabetes, glucocorticoid secretion increases secondary to hyperglycemia and is associated with an extensive list of disease complications. Levels of cortisol in humans, or corticosterone in rodents, are usually measured as transitory biomarkers of stress in blood or saliva. Glucocorticoid concentrations accumulate in human or animal hair over weeks and could more accurately measure the cumulative stress burden of diseases like chronic diabetes. In this study, corticosterone levels were measured in hair in verified rodent models of diabetes mellitus...

BACKGROUND: Excessive hair is undesirable and represents both a social and emotional burden, especially among females. Laser hair removal (LHR) has gained popularity in the past 2 decades. It is a common practice to instruct patients not to pluck or wax their hair before undergoing LHR; only shaving is allowed to improve the efficacy of the LHR. OBJECTIVE: To compare the percentage of hair reduction in preshaved versus prewax epilated axillae after LHR in healthy adult Saudi females...

RATIONALE: Oxygen isotope ratios (δ(18) O values) of hair largely reflect features of regional hydrology while strontium isotope ratios ((87) Sr/(86) Sr) are thought to reflect bedrock geology; combination of both isotope signatures may provide greater capacity for determining provenance and reconstructing travel history of an organism. To test this hypothesis, we compared the O-Sr isotope profiles of hair from domestic horses with known residency histories. METHODS: Tail hairs were collected from a pair of horses pastured together for a period of 16 months, one of which lived in a different location for the 8 months prior...

INTRODUCTION: Allergic contact dermatitis is an important cause of hand eczema. Patch testing is the only investigation available to prove the diagnosis of allergic contact dermatitis. Exposures to allergens differ according to geographical, occupational, economic and social factors. Accordingly, patterns of allergic contact dermatitis differ in different parts of the world and different regions of the same country. AIM: To study the causes of allergic contact dermatitis in adult patients with hand eczema with the help of patch testing...

An improvement of the penetration efficiency combined with the controlled release of actives in the skin can facilitate the medical treatment of skin diseases immensely. Dexamethasone (Dx), a synthetic glucocorticoid, is frequently used for the treatment of inflammatory skin diseases. To investigate the penetration of nano-sized lipid particles (NLP) loaded with Dx in comparison to a commercially available base cream, different techniques were applied. Electron paramagnetic resonance (EPR) spectroscopy was used to monitor the penetration of Dx, which was covalently labeled with the spin probe 3-(Carboxy)-2,2,5,5-tetramethyl-1-pyrrolidinyloxy (PCA)...

The proportion of men receiving non-surgical cosmetic procedures has risen substantially in recent years. Various physiologic, anatomic, and motivational considerations differentiate the treatments for male and female patients. Nevertheless, research regarding approaches to the male cosmetic patient is scarce. We sought to provide an overview and sex-specific discussion of the most popular cosmetic dermatologic procedures pursued by men by conducting a comprehensive literature review pertaining to non-surgical cosmetic procedures in male patients...

BACKGROUND: Craniotomies for trauma are associated with a significant risk of wound complications. We report a case in which a chronic nonhealing draining sinus was caused by an ectopic epidermal lining deep to the craniotomy bone flap, adherent to the underlying dura. CASE DESCRIPTION: A 61-year-old man was examined for a 3-year-old, nonhealing scalp wound resulting after a traumatic brain injury. His initial surgery consisted of an intracranial hematoma evacuation through a temporoparietal craniotomy; this was complicated by wound dehiscence and a chronic sinus draining clear fluid that did not resolve with antimicrobial therapy...

Reconstructing congenital auricular defects due to hemifacial microsomia (HFM) is often required to deal with low hairline and defects of the temporal fascia/muscular systems. In this report, we present two cases of HFM patients (16-year-old and 20-year-old) with positional anomaly of the remnant lobule and 95% low hairline, who were treated with serratus anterior fascial flap (SFF) at the second stage of auricular construction. At the first stage, 3D costal cartilage framework was placed following the removal of hair-bearing skin, and was resurfaced with the pericranial flap...

Stress hormones (glucocorticoids), incorporated into hair/fur and faeces, have been proposed as biomarkers of overall health in wildlife. Although such biomarkers may be helpful for wildlife conservation and management, their use has rarely been validated. There is a paucity of studies examining the variation of stress hormones in mammals and how they relate to other health measures, such as parasitism. Parasites are ubiquitous in wildlife and can influence the fitness of individual animals and populations...

OBJECTIVE: STIs are the most common infections among adults. Concurrently, pubic hair grooming is prevalent. Small-scale studies have demonstrated a relationship between pubic hair grooming and STIs. We aim to examine this relationship in a large sample of men and women. DESIGN: We conducted a probability survey of US residents aged 18-65 years. The survey ascertained self-reported pubic hair grooming practices, sexual behaviours and STI history. We defined extreme grooming as removal of all pubic hair more than 11 times per year and high-frequency grooming as daily/weekly trimming...

BACKGROUND: Acaricides are used to treat and prevent tick infestations, and a common clinical scenario is to administer an acaricide on observing an attached tick. Consequently, immediate acaricidal efficacy (onset of activity and speed of kill) results are clinically valuable. This study evaluated the immediate efficacy of four commercially available acaricides against adult Rhipicephalus sanguineus (sensu lato). METHODS: Forty dogs were blocked on hair length and tick carrying capacity, then randomly assigned to receive one of four treatments (fluralaner, sarolaner, imidacloprid + permethrin, or afoxolaner) or left untreated as controls...
