Woolly hair may occur as an isolated problem of cosmetic concern or can be a part of a systemic disease (woolly hair syndrome) with underlying fatal cardiomyopathy. Two characteristic associations of woolly hair syndrome are Naxos disease and Carvajal syndrome. Naxos disease is characterized by woolly hair, palmoplantar keratoderma, and arrythmogenic right ventricular cardiomyopathy.In this report we describe a case of a young girl who presented with heart failure and was subsequently diagnosed as a case of generalized woolly hair with biventricular arrythmogenic cardiomyopathy...

BACKGROUND/PURPOSE: Hair straighteners are very popular around the world, although they can cause great damage to the hair. Thus, the characterization of the mechanical properties of curly hair using advanced techniques is very important to clarify how hair straighteners act on hair fibers and to contribute to the development of effective products. On this basis, we chose two nonconventional hair straighteners (formaldehyde and glyoxylic acid) to investigate how hair straightening treatments affect the mechanical properties of curly hair...

We selected 1235 decapeptides from human hair proteins encoded by human genes of keratins and keratin associated proteins. The peptides were linked to glass arrays and screened for their affinity towards a solution of human hair extracted keratin fraction. Based on the physicochemical properties of the peptides, ten variables were studied: content of different types of amino acid side chains (cysteine, hydrophobic, polar, basic, acidic, aromatic rings, amide, alcohol side chains), isoelectric point, and net charge...

BACKGROUND Umbilical pilonidal sinus (UPS) is a rare disease of young, hirsute, dark men with deep navels and poor personal hygiene. UPS could easily be misdiagnosed and mistreated due to its rarity and lack of awareness of the condition by physicians. However, the diagnosis is easy to establish with physical examination and a detailed history. Although it is being diagnosed and reported more frequently, there is still no consensus regarding best treatment options. CASE REPORT In this report, we present two cases of UPS, one in a man and one in a woman, who had typical symptoms of pain, swelling, and intermittent malodorous discharge from the umbilicus...

BACKGROUND: Application of herbal paste and oil to a dog's coat and body before rinsing (often combining with shampooing) is a cosmetic therapy available in Japan. It is highly appreciated by users, who claim that the treatment makes the coat shinier, improves volume and eliminates tangles. However, there has been no scientific evaluation of such treatments. HYPOTHESIS/OBJECTIVES: Improvement of hair condition is derived from oils such as sebum and conditioning oils because chemicals are not used...

There is a growing interest in hair cortisol concentrations as a valuable biomarker for the assessment of metabolic diseases and chronic psychological stress. Fifty-three volunteers were recruited, and hair segments proximal to the scalp were collected from each individual. A cost-effective ball mill was used for the preparation of hair samples, and ELISA was performed to analyze cortisol concentrations. Results indicate that the frequency of hair washing affects the hair cortisol concentration. The group that washed their hair every day had significantly lower cortisol concentrations than the group that washed it less often...

Trace elements, including zinc (Zn) and germanium (Ge), are essential for health; deficiency or excess levels of trace elements results is harmful. As a result of industrial and agricultural production, Pb widely exists in people's living environment. It is absorbed mainly through the respiratory and digestive tracts, producing systemic harm. Reference values for a normal, healthy population are necessary for health assessment, prevention and treatment of related diseases, and evaluation of occupational exposures...

K Brannigan, L L Touil, A Y Fattah
Pilomatrixomas are benign, calcified epitheliomas of the hair follicle, predominately affecting children and commonly presenting in the head and neck region. The current literature is almost unanimous in recommending surgical excision. Reconstruction of these defects may require the need for a skin graft, resulting in poor cosmetic outcome and donor site morbidity. We present two cases demonstrating the benefits of minimal access incisions for pilomatrixomas in children. We recommend that multiple or recurrent lesions should prompt referral to a specialist for management and long-term follow-up...

Volumetric Muscle Loss (VML) injuries exceed the considerable intrinsic regenerative capacity of skeletal muscle resulting in permanent functional and cosmetic deficits. VML and VML-like injuries occur in military and civilian populations, due to trauma and surgery as well as a host of congenital and acquired diseases/syndromes. Current therapeutic options are limited, and new approaches are needed for more complete functional regeneration of muscle. A potential solution is human hair derived keratin (KN) biomaterials that may have significant potential for regenerative therapy...

BACKGROUND: Although keratin hydrolysates have become established as standard components in hair and nail cosmetics, studies on the moisturizing effects of keratin hydrolysates do not appear among contemporary literature. OBJECTIVES: To test if adding keratin hydrolysate into an ointment base increases hydration of the skin and improves skin barrier function, or diminishes trans-epidermal water loss. METHODS: Formulations were prepared containing 2%, 4%, and 6% keratin hydrolysates (based on weight of the ointment base)...

BACKGROUND: Treatment of coup de sabre must remain conservative until the disease is no longer in an active state. When activity has ceased, some operative intervention is safe and effective for the correction of deformity. While hair transplantation showed high survival rates for the correction of cicatricial alopecia, it has rarely reported to be performed for the correction of coup de sabre. OBJECTIVE: To assess the therapeutic possibility of hair transplantation for the correction of coup de sabre...

BACKGROUND: Cosmetic surgery among male patients has become increasingly popular. The face-lift technique is different in male patients, specifically regarding preservation of hair follicles, restoration of a youthful and well appearance, and reduction of the risk of hematoma. METHODS: A retrospective review of a single surgeon's past 20 years of consecutive male rhytidectomies revealed a cohort of 83 patients. A control group was created by random selection of 83 age-matched female rhytidectomy patients during the same period...

Lei Chen, Qi Xing, Qiyi Zhai, Mitchell Tahtinen, Fei Zhou, Lili Chen, Yingbin Xu, Shaohai Qi, Feng Zhao
Split thickness skin graft (STSG) implantation is one of the standard therapies for full thickness wound repair when full thickness autologous skin grafts (FTG) or skin flap transplants are inapplicable. Combined transplantation of STSG with dermal substitute could enhance its therapeutic effects but the results remain unsatisfactory due to insufficient blood supply at early stages, which causes graft necrosis and fibrosis. Human mesenchymal stem cell (hMSC) sheets are capable of accelerating the wound healing process...

Pregnant women are exposed to various chemical products at home and at work. Some of these products contain endocrine-disrupting chemicals (EDCs) such as cosmetics, pesticides, industrial chemicals, heavy metals, plastics or medications that could alter sexual differentiation and increase the risk of hypospadias. We evaluated maternal occupational and household exposures that could constitute risk factors for hypospadias. From 2011 to 2014, we enrolled 57 full-term newborns with hypospadias and three randomly selected controls per case (162 control newborns), matched for gestational age, from 11 maternity units in Picardy, France...

REVIEW
Brandon E Cohen, Sameer Bashey, Ashley Wysong
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...
