Hair removal

INTRODUCTION AND IMPORTANCE: Trichotillomania and tricophagia, characterized by compulsive hair-pulling and subsequent ingestion which results in a compact mass of hair called trichobezoar. It represents an uncommon psychiatric disorder, especially in young children. CASE PRESENTATION: This case report describes a distinctive and rare occurrence of trichotillomania, tricophagia and trichobezoar in a 11-year-old male child. Concerns raised by the parents regarding noticeable hair loss, who initially presented to medical outdoor patient with complaints of abdominal pain on and off from the last one year...

BACKGROUND: Pubic hair grooming involves the partial or complete removal of pubic hair, and it is a common practice among men and women. Grooming is more prevalent in women, who employ various methods such as shaving, waxing and laser removal. However, it is associated with variable rates of post-grooming adverse outcomes including lacerations and sexually transmitted infections (STIs). To the best of our knowledge, this is the first systematic review and meta-analysis comparing women's sexual health outcomes between those who groom and those who don't...

KEY CLINICAL MESSAGE: Fox-Fordyce disease is a recognized adverse effect of depilating lasers. It should be considered among the differential diagnoses of the pruritic perifollicular papules that occur at the hair removal laser treatment site, including Alex/Diode laser. ABSTRACT: Fox-Fordyce disease (FFD) is an uncommon skin disorder affecting the apocrine sweat glands and presents as pruritic skin-colored papules, mainly on the axillary and pubic areas. Some predisposing factors are proposed, including hormonal changes...

Identifying tumors or wounds on the scalp is difficult because hair blocks the vision during surgery and suturing. In the meantime, we have commonly used hairpins to hold the hair for a clearer view; however, we would like to suggest a new method, a "hair-fixing sheet," consisting of hook-like surface. We applied the two methods, hair-fixing sheets and hairpins, assuming several situations. In these situations, it was possible to fix a wider range or various shapes more conveniently using a hair-fixing sheet than using several hairpins at a similarly low cost...

Mature teratomas, also known as ovarian dermoid cysts, are benign embryonal tumors that develop slowly. One of the following imaging techniques is commonly employed to evaluate these cysts: transvaginal ultrasound, pelvic ultrasonography, magnetic resonance imaging, or computed tomography. The two surgical methods most frequently used for removing persistent or very large cysts are laparoscopy and laparotomy. A 42-year-old female, who is P3L1D2 with a history of previous cesarean section, presented with an abdominal mass that had been gradually increasing in size over the past five months...

Hair tourniquet syndrome is a rare condition that can cause ischemia and necrosis secondary to hair fibers constricting a patient's appendages. Typically, the syndrome affects patients aged two to six months. Hair tourniquet syndrome often involves the toes, fingers, or genitalia, and it has been rarely reported to have oropharyngeal manifestations. Accurate and timely treatment of this syndrome is imperative to save the involved appendage. We discuss a case of a six-month-old female who presented to the emergency room (ER) with increased agitation and was found to have hair tourniquet syndrome of the uvula, requiring the removal of the foreign body in the operating room (OR)...

BACKGROUND: Previous studies have shown that the traditional Chinese medicine (TCM) called "compound healthy ear agent" (CHEA) had anti-apoptosis effects in cochlear hair cells and spiral ganglion neurons, and could protect mice hearing against presbycusis or age-related hearing loss (AHL), as well as aminoglycoside antibiotic-induced ototoxicity. Because its mechanisms of action are still unclear, we investigated the mechanism of action of CHEA against AHL in mice using proteomics techniques...

Penile inversion vaginoplasty (PIV) is a gender-affirming surgical procedure where the skin of the penis and scrotum is reconstructed into the neovaginal lining. To prevent hair-bearing skin from becoming incorporated into the neovaginal canal, transgender patients are encouraged to undergo hair removal of their external genitalia. The goal of this preoperative hair removal is to minimize the risk of potential hair-related complications after vaginoplasty. To better support patients seeking preoperative hair removal and identify current treatment barriers, we surveyed patients about their progress and satisfaction with hair removal...

Trace element concentrations in toenail clippings have increasingly been used to measure trace element exposure in epidemeological research. Conventional methods such as inductively coupled plasma mass spectrometry (ICP-MS) and high-performance liquid chromatography ICP-MS (HPLC-ICP-MS) are commonly used to measure trace elements and their speciation in toenails. However, the impact of the removal of external contamination on trace element quantification has not been thoroughly studied. In this work, the microdistribution of trace elements (As, Ca, Co, Cu, Fe, K, Mn, Ni, Rb, S, Sr, Ti, and Zn) in dirty and washed toenails and the speciation of As in situ in toenails were investigated using synchrotron X-ray fluorescence microscopy (XFM) and laterally resolved X-ray absorption near edge spectroscopy (XANES)...

Endocrine-disrupting chemicals (EDC) are compounds that alter functions of the endocrine system due to their ability to mimic or antagonize endogenous hormones, or that alter their synthesis and metabolism, causing adverse health effects. Human biomonitoring (HBM) is a reliable method to assess human exposure to chemicals through measurement in human body fluids and tissues. It identifies new sources of exposure and determines their distribution, thereby enabling detection of the most exposed populations. Blood and urine are commonly used for HBM of EDC, but their interest is limited for compounds presenting short half-lives...

PURPOSE: To describe a novel technique of nasolacrimal foreign body extraction in dogs by using a 20G vitreoretinal forceps introduced through the superior lacrimal punctum. METHODS: A retrospective review of the medical records of dogs with dacryocystitis due to nasolacrimal foreign bodies between the years 2001 and 2022 was performed. We recorded the breed, age, affected eye, type and number of foreign bodies, concomitant diseases, and the use of imaging techniques...

Unwanted hair is a common concern among patients presenting to pediatric dermatology clinics, and parents and patients alike inquire about the safety of methods employed for elective removal. Various methods of hair removal exist with different levels of invasiveness and permanence, from simple mechanical depilation to light-based therapies. All methods of hair removal appear to be safe and generally well tolerated in children, and there are no age restrictions to any modality. In this review, we aim to address the available literature on the safety and efficacy of hair removal modalities in pediatric patients and propose guidance on how to manage requests for at-home and in-office therapies within an ethical framework...

The function and evolutionary background of the hairs on the shells of terrestrial gastropods is largely unknown. Many hypotheses proposed by malacologists have never been proven, and the long-held hypothesis of mechanical stability in wet environments has been rejected by recent studies. It would therefore be worthwhile to reexamine other hypotheses regarding the adaptive significance of shell hairs. We investigated the defense function of shell hairs against a specialist predator, the snail-eating firefly, in the long-haired snail Moellendorffia diminuta...

In the search of new enzymatic activities with a possible industrial application, we focused on those microorganisms and their molecular mechanisms that allow them to succeed in the environment, particularly in the proteolytic activity and its central role in the microorganisms' successful permanence. The use of highly active serine proteases for industrial applications is a modern need, especially for the formulation of detergents, protein processing, and hair removal from animal skins. This report provides the isolation and identification of a highly proteolytic fragment derived from DegQ produced by a Pseudomonas fluorescens environmental strain isolated from a frog carcass...

β-Nicotinamide mononucleotide (NMN) has shown promising effects on intestinal health, and it is extensively applied as an anti-aging and Alzheimer's disease therapeutic, due to its medicinal properties. The effects of NMN on the growth of mouse hair were observed after hair removal. The results indicated that NMN can reverse the state of hair follicle atrophy, hair thinning, and hair sparsity induced by dihydrotestosterone (DHT), compared to that of minoxidil. In addition, the action mechanisms of NMN promoting hair growth in cultured human dermal papilla cells (HDPCs) treated with DHT were investigated in detail...

BACKGROUND: Several different parameters play a role in the transition of hair follicles to the anagen phase, with the role of androgens, progesterone, estrogen hormones, and receptors being significant. OBJECTIVES: The effectiveness of Laser Hair Removal (LHR) and pain tolerance during application were investigated during three different phases of the menstrual cycle. METHODS: 48 axillae were randomly divided into three groups: menstruation, ovulation, and luteal...

The study investigated inter-species variation in particulate matter (PM) accumulation, wash-off, and retention on green wall plants, with a focus on leaf characteristics. Ten broadleaf plant species were studied in an experimental green wall. Ambient PM concentrations remained relatively stable throughout the measurement period: PM1 : 16.60 ± 9.97 μgm-3 , PM2.5 : 23.27 ± 11.88 μgm-3 , and PM10 : 39.59 ± 25.72 μgm-3 . Leaf samples were taken before and after three rainfall events, and PM deposition was measured using Scanning Electron Microscopy (SEM)...

UNLABELLED: The function of prestin (SLC26a5), an anion transport family member, has evolved to enhance auditory sensitivity and frequency selectivity by providing mechanical feedback via outer hair cells (OHC) into the organ of Corti. The frequency extent of this boost is governed by the voltage-dependent kinetics of the protein's charge movements, otherwise known as nonlinear capacitance (NLC) that we measure in membrane patches under voltage clamp. Here we extend our previous studies on guinea pig OHCs by studying the frequency response of NLC in the mouse OHC, a species with higher frequency auditory needs...

BACKGROUND: In Australia, a man cannot donate blood if he has had sex with another man within the past 3 months. However, this policy has been criticized as being discriminatory as it does not consider lower risk subgroups, and led to calls for modifications to the policy that more accurately distinguish risk among gay, bisexual, and other men who have sex with men (GBM). STUDY DESIGN AND METHODS: We used data from a nationally representative survey to estimate the proportion of GBM aged 18-74 years old who would be eligible to donate under current criteria and other scenarios...

INTRODUCTION: Performing laser hair removal treatments on dark skin is limited by the quantity of melanin within the skin. To minimize side effects, lower values of fluence are selected when using standard 755 or 810 nm diode lasers. However, this approach may limit the effectiveness of the procedure, particularly when treating areas with thin and less pigmented hair, which is often the case in facial regions. To improve results, high-power triple wavelength diode lasers can be used...
