Onychomycosis is a chronic and intractable disease whose prevalence increases during aging. In elderly patients, if onychomycosis is left untreated and progresses to a severe stage it may cause functional decline of the lower limbs due to foot pain. This could lead to a decline in activities of daily living and secondary impairment such as cognitive decline. Thus, the treatment of onychomycosis in elderly patients is important. We have previously shown that fosravuconazole is relatively safe and effective for onychomycosis in elderly patients...

The Korea Nurses' Health Study (KNHS) is an ongoing, large-scale, prospective cohort study of female nurses, focusing on the effects of occupational, environmental, and lifestyle factors on the health of women. The first KNHS survey was performed in 2013-2014 (n=20,613). As of December 2023, 11 follow-up surveys have been conducted. Participants who were pregnant were asked to participate in the early pregnancy survey (n=2,179) and postpartum survey after giving birth (n=2,790). The main variables included sociodemographic, work-related, lifestyle, physical, mental, and women's health factors...

Research on the neurodevelopmental effects of metal(loid)s has focused mainly on outcomes assessed at one time point, even though brain development progresses over time. We investigated biomarkers of perinatal exposure to metals and changes in child behavior over time. We followed 268 participants from the prospective New Hampshire Birth Cohort Study between birth and age 5 years. We measured arsenic (As), copper (Cu), manganese (Mn), lead (Pb), selenium (Se), and zinc (Zn) in toenails from 6-week-old infants...

OBJECTIVE: Previous epidemiological and experimental studies have yielded conflicting results regarding the influence of human micronutrient levels on the risk of colorectal polyps (CP). In our study, we conducted a two-sample Mendelian randomization (MR) investigation to probe the link between 13 human micronutrients (calcium, selenium, magnesium, phosphorus, folate, vitamins B-6, B-12, C, D, beta-carotene, iron, zinc, and copper) and the genetic susceptibility to CP. METHODS: Summary statistics for CP (n = 463,010) were obtained from pan-European genome-wide association studies, and instrumental variables for 13 micronutrients were screened from published genome-wide association studies (GWAS)...

Green nail syndrome (GNS) is a rare diagnosis in which a patient presents with green-yellow, green-blue, or green-brown discoloration of a finger or toenail. It occurs due to a Pseudomonas aeruginosa  infection of the nail.  Pseudomonas aeruginosa  produces pigments that can infuse into the underside of the nail plate, creating a color change. Here, we present the case of a 34-year-old female with a green-brown area of discoloration of her right middle finger in which the diagnosis of GNS was made...

The presence of ostarine, a selective androgen receptor modulator (SARM) in an athlete's sample constitutes one of the most frequent anti-doping rules violation. It is possible to challenge this violation but it is the athlete who has to demonstrate he / she is innocent. The conditions to evidence no fault or negligence are mostly based on 2 points: 1. the athlete or his/her legal representative must present verified circumstances of contamination and the source of contamination must be identified; and 2. there must be verified claims by the athlete about the fact that he / she did not knowingly take the prohibited substance, i...

BACKGROUND: Onychomycosis is a chronic nail disorder commonly seen by healthcare providers; toenail involvement in particular presents a treatment challenge. OBJECTIVE: To provide an updated estimate on the prevalence of toenail onychomycosis. METHODS: We conducted a literature search using PubMed, Embase and Web of Science. Studies reporting mycology-confirmed diagnoses were included and stratified into (a) populations-based studies, and studies that included (b) clinically un-suspected and (c) clinically suspected patients...

BACKGROUND: Some of the most common complaints addressed by primary care physicians (PCPs) require manual procedures, such as lacerations repair, abscesses drainage, ingrown toenails removal, dry needling for myofascial pain syndrome, and Epley maneuver for treating benign paroxysmal positional vertigo (BPPV). The aim of this study was to describe the procedural skills workshops program for PCPs implemented in Maccabi Healthcare Services and to investigate how many PCPs have participated and used the skills since the program's inception in 2017...

Yellow nail syndrome (YNS) can induce bilateral exudative pleural effusion; however, to the best of our knowledge, no standard treatment for YNS has been established. The present study describes a patient with YNS for whom the pleural effusion was controlled by prednisolone. A 73-year-old man was referred to the University of Tsukuba Hospital (Ibaraki, Japan) complaining of shortness of breath, which was diagnosed as being due to bilateral pleural effusion. Based on the presence of yellowing and growth retardation of the toenails, lymphedema, bilateral exudative pleural fluid of unknown etiology, and lymphatic congestion on lymphoscintigraphy, the patient was diagnosed with YNS...

Background  Ingrown toenail is a common condition that results in chronic pain, recurrent infections, and difficulty in performing daily activities. Our aim is to compare two surgical methods for the treatment of ingrown toenails: wedge resection with curetting versus wedge resection curetting followed by electrocauterization of the nail bed. Methods  A prospective, comparative study that included 130 patients with ingrown toenails. All patients had stage II or III disease. We divided the participants into two groups according to the type of surgery and all patients were followed up for 6 months...

OBJECTIVE: The aim of the surgical intervention is the elimination of infections, ulceration and pain caused by ingrown nails (unguis incarnatus). INDICATIONS: A surgical intervention is recommended for ingrown nails (the large toenail is most frequently affected) in stage III and higher (according to the Mozena classification) as well as in cases of nail plate defects and recurrences. CONTRAINDICATIONS: In cases where a disturbance of wound healing is expected and general contraindications for surgery...

The growing demand for natural treatments has raised concerns among clinicians due to limited scientific evidence supporting their use. This review article addresses the issue by assisting dermatologists and general practitioners in recommending natural treatments for the following common nail disorders: nail brittleness, onychomycosis, periungual verrucae, paronychia, chloronychia, nail psoriasis, nail lichen planus, onychocryptosis, onycholysis, and congenital malalignment of the great toenail. One limitation is the scarcity of existing reviews on natural treatment options for nail disorders in the literature...

BACKGROUND: Psoriatic patients may experience the coexistence of onychomycosis (OM). However, the evaluation of OM in psoriatics has been hindered by potential clinical differences from OM in non-psoriatics. OBJECTIVE: To assess and compare dermoscopic features between toenail OM in psoriatic and in non-psoriatic patients. PATIENTS AND METHODS: Between September 2020 and September 2023, dermoscopy was conducted on 183 affected toenails by OM in psoriatics and 232 affected toenails by OM in non-psoriatics in two centres...

Birds have a diverse community of "permanent" arthropods that complete their entire life cycle on the body of the host. Because some of these arthropods are parasites that reduce host fitness, birds control them by grooming, which consists of preening with the beak and scratching with the feet. Although preening is the primary component of grooming, scratching is essential for controlling arthropods on the head and neck, which cannot be preened. Several unrelated groups of birds have evolved comb-like pectinate claws on the middle toenail of each foot...

We conducted a cross-sectional study on the clinical and mycological features of onychomycosis in patients in the dermatology ward of Iwate Medical University Hospital, an acute care hospital. Of the 226 hospitalized patients, 73 (32.3%) had onychomycosis and 61 (26.9%) were diagnosed after admission. The toenail was the most common site of onychomycosis (94.5%), while toenail plus fingernail and fingernail only sites were 4.1% and 1.4%, respectively. The most common clinical form of onychomycosis was distal and lateral subungual onychomycosis (79%) with Trichophyton rubrum (66...

INTRODUCTION: Leprosy is a chronic granulomatous infectious disease, mainly affecting the skin and peripheral nerves, caused by the obligate intracellular bacteria Mycobacterium leprae. The disease has been discussed in several review articles in recent research, but as far as we know, only a few have addressed the effects of leprosy on nails, especially those who examine the dermoscopic features of nails in leprosy patients. PURPOSES: We aimed to document nail changes in leprosy patients and identify any particular findings through dermoscopic examination...

BACKGROUND: Cadmium (Cd) is classified as a class 1 carcinogen by the IARC, yet uncertainty persists regarding the total burden of cancer (incidence and mortality) caused by exposure to it, due to the still limited evidence with regard to its aetiological role in cancer at several body sites. OBJECTIVES AND METHODS: We searched PubMed and EMBASE for meta-analyses and original articles published by February 1st, 2024, that focused on the link between cadmium measured in biological samples (blood, urine, finger-/toe-nails, and hair) and site-specific cancer risk and mortality...

Ostarine, also known as MK-2866 or enobosarm, is a selective androgen receptor modulator (SARM). It has anabolic properties and as such is widely used in doping, accounting in 2021 for 25 % of the adverse analytical findings (AAF) among the class S1.2 "Other anabolic agents" of products banned by the World Anti-Doping Agency, to which it belongs. But in some cases, it can be responsible for an AAF following contamination. We report the case of an athlete who contaminated herself by exchanging body fluids while kissing her boyfriend, who took 25 mg per day of MK-2866 for 9 days prior to the athlete's AAF (urinary concentration evaluated at 13 ng/mL) without her knowledge...
