The association between foot alignment and the development of ingrown toenails: A case-control study in a young adult military population.

BACKGROUND: This case-control study aimed to explore an association between foot alignment and development and presentation of the ingrown toenail. METHODS: Radiographs were evaluated for hallux interphalangeal angle (HIA), hallux valgus angle (HVA), talonavicular coverage angle (TNC), talo-first metatarsal (Meary's) angle, and calcaneal pitch angle (CP), as well as medial sesamoid position in a cohort of 103 young and healthy patients (mean age of 20.5 years) with ingrown toenails. A control group of 63 patients was included, and the radiographic parameters were compared. Subgroup analysis was performed in patients with lateral (n = 65) or medial (n = 38) nail fold involvement. RESULTS: The overall study group demonstrated a larger TNC and Meary's angle and smaller CP than the control group, while no significant difference was found regarding the HIA and HVA. The lateral nail fold group had a larger HIA when compared to the medial nail fold group. Multiple regression analysis revealed that for ingrown toenail development, the only risk factor was a decrease in the CP. In the case of lateral nail fold involvement, an increase in the HIA found to be the only factor. CONCLUSION: A lower medial longitudinal arch seems to be a predisposing factor in developing an ingrown toenail. The lateral nail fold involvement was associated with lateral deviation of the distal phalanx. The result of this study could provide information on prevention, treatment, recurrence, and patient counseling of an ingrown toenail in otherwise young and healthy individuals.

A fast and effective solution for ingrown toenail: Creation of a 2-mm space between tissue and nail by sutureless lateral longitudinal excision.

Nails have both functional and aesthetic importance. Undertreatments cause frequent recurrences affecting its functionality, while over-treatment spoils the aesthetic view. To describe the most practical and aesthetic method to treat ingrown toenail. All patients with ingrown toenail who applied to outpatient clinics of General Surgery Department between 2013 and 2019 were enrolled. A 2-mm space between tissue and nail by lateral longitudinal excision was created with only minimal matricectomy, under local anaesthesia. A total of 2334 surgical procedures were performed in 2118 patients. Recurrence rate was 1.7% during 36-month follow-up, most (70.7%) in younger men (22 years). The location of the lesions (right/left, medial/lateral or bilateral) did not show difference (p > 0.05 for each). Predisposing factors were tight-fitting footwear (4.5%), incorrect nail-trimming (3%), genetic tendency (2.8%), obesity (2.1%) and trauma (0.75%); but each was p > 0.05. Mean operation time was 3 min. There was no important complication, except hematoma (0.89%) and infection (0.68%). Mean healing time was 10 days and patients returned to daily activities in 3 days. Longitudinal excision with minimal matricectomy technique provides all dead tissue and diseased parts of nail and soft tissue to be removed. It is simple, cost-effective, satisfactory and aesthetic.

Review of onychocryptosis: epidemiology, pathogenesis, risk factors, diagnosis and treatment.

Ingrown toenail, or onychocryptosis, is a highly prevalent nail condition that occurs when the nail edge grows into the periungual dermis. It most frequently affects the hallux and has a biphasic presentation, being most common in the second and fifth decades. It is often painful and may be debilitating in severe cases. Risk factors include trauma, weight changes, poor nail-cutting technique, and hyperhidrosis. Both conservative and surgical treatments have been described, and choice of therapy is dependent on patient co-morbidities, severity, and associated symptoms. This review covers the epidemiology, risks factors, pathogenesis, evaluation, and staging of ingrown toenails, as well as, treatment options. Although there is an unmet need for clinical trials comparing therapies, current recommendations are to treat conservatively and then proceed to surgical therapies if symptoms persist.

Ingrown Toenails During Chemotherapy and Stem Cell Transplantation in Children With Hematologic Malignancies and Solid Tumors.

BACKGROUND: At our institution, we noted that children with hematologic malignancies and solid tumors often suffered from ingrown toenails (IGTNs) during hospitalization for chemotherapy and stem cell transplantation. However, only few reports have dealt with IGTNs in the above setting. PROCEDURE: Between August 2007 and July 2017, 180 children who received treatment for hematologic malignancies and solid tumors at our institute were enrolled in this study. Twelve patients with insufficient data and 7 patients with past histories of IGTNs were excluded. A total of 161 patients were analyzed. Median age at admission was 7.9 years (range, 1.0 to 25.4 y), with 92 males and 69 females. Diagnoses were hematologic diseases in 128 patients, including acute lymphoblastic leukemia (ALL) in 75 patients, and solid tumors in 33 patients. RESULTS: A total of 22 patients (13.7%) suffered from IGTNs (or toe paronychia) during hospitalization. Multivariable analysis disclosed a strong correlation between the occurrence of IGTNs and older age (over 9.0 y) and ALL. CONCLUSIONS: Patient-related factors, such as age over 9 years and ALL were associated with IGTNs. This is the first report of a survey on IGTNs in patients with hematologic malignancies and solid tumors hospitalized for chemotherapy and stem cell transplantation.

Epidemiology and bone-related comorbidities of ingrown nail: A nationwide population-based study.

Although ingrown nail (IN) is common, there is no large-scale study regarding its epidemiology and risk factors, such as foot deformity. The purpose of this study is to determine the demographics of IN and clarify its association with bone-related comorbidities of the ankle, foot and toe. Patients in a representative sample cohort of the National Health Information Database of South Korea from 2004 to 2013 who had IN were compared with a control group without IN. Ten-year overall incidence was 307.5/100 000 person-years (95% confidence interval, 304.1-310.9). IN incidence and prevalence showed an increasing trend, and IN was more common in women than in men. Incidence showed bimodal peaks, among teenagers and among participants in their 50s. The IN group showed more common valgus deformity (64.3%) than did the control group (61.6%), and flat foot was also a significant risk factor of IN. There were increasing tendencies of IN incidence and prevalence among females. Confirmed bone deformity, especially acquired valgus or varus deformity, and flat foot were associated with IN.

Risk Factors and Frequency of Ingrown Nails in Adult Diabetic Patients.

The present study evaluated the properties of nails, frequency of ingrown nails in patients with type 2 diabetes mellitus (DM), risk factors for developing ingrown nails, and effect of diabetic polyneuropathy and vasculopathy on the development and outcome of ingrown nails. Our 6-month epidemiologic prospective study included 300 patients with type 2 DM attending a DM outpatient clinic for routine examinations. The general characteristics and foot changes of the study population were investigated. Diabetic polyneuropathy and vasculopathy were evaluated using a biothesiometer, monofilament tests, and arterial Doppler ultrasonography. The frequency of ingrown nails was 13.6%. Multivariate analysis with logistic regression showed that body mass index (odds ratio [OR] 1.077, 95% confidence interval [CI] 1.007 to 1.15; p = .03), previous trauma (OR 2.828, 95% CI 1.017 to 7,867, p = .042), a weak dorsalis pedis pulse (OR 2.72, 95% CI 1.17 to 6.30, p = .02), trimming type (OR 2.3, 95 CI 1.06 to 4.98), p = .35), onychogryphosis (OR 9.036, 95% CI 2.34 to 34.87, p = .001), and subungual hyperkeratosis (OR 4.3, 95% CI 1.99 to 9.3, p = .001) were predictive variables for ingrown nails in our population. The incidence of onychomycosis was significantly greater in patients with ingrown nails (p = .032) than in patients without ingrown nails. The nail curvature ratio was greater in the patients with ingrown nails than in the group with normal nails. Arterial Doppler ultrasound examinations showed peripheral arterial disease in 19 patients (46.9%) with ingrown nails. The prevalence of ingrown nails was greater in the patients with DM than in the healthy population. Our results indicate that nail type, nail morphology, and diabetic vasculopathy affect the formation and evolution of ingrown nails.

Relation Between Nail Consistency and Incidence of Ingrown Toenails in Young Male Runners.

BACKGROUND: This study examines the possible influence of factors such as nail shape and consistency, sex, and sports activity on the development of the most common nail disorders in a population of young people. METHODS: The nail plates of 140 young people (66 females and 74 males) were studied. Of these 140 participants, 72 were runners who trained more than 10 hours a week and competed regularly, and 68 did not habitually do any sports activity. Nail shape, consistency, and disorders were examined, taking into account the sex of the participants and their sports activity. RESULTS: A hard nail consistency is more frequent in runners (74.4%) than in people who do no sports activity (25.6%). In contrast, a soft nail consistency is more prevalent in participants who do no sports activity (70%) than in runners (30%). It was also shown that onychocryptosis is related to sex, as females had a higher prevalence of this nail disorder (57.8%, P = .016). However, young male runners showed the highest and most significant percentage of the presence of onychocryptosis (74.1%; P = .002). CONCLUSIONS: Sports activity by young male runners whose nails have a hard consistency seems to be directly related to the high incidence of onychocryptosis in this population.

Hábitos podológicos en personas con alteraciones ungueales.

OBJECTIVE: To determine the prevalence of onychocryptosis and onychomycosis confirmed by culture in subjects attending a Podiatric University Hospital and to describe their podiatric habits. METHOD: Cross-sectional study of prevalence. The study was carried out at the Clinic University of Podology of A Coruna University (Ferrol, Spain). Review of 1082 clinical histories, of which 170 were selected, persons who had onychocryptosis diagnosed clinically. The presence of onychomycosis confirmed by cultivation, presence of onychocryptosis through clinical diagnosis and a questionnaire was handed out of podologic habits. RESULTS: Mean age of the total sample (n = 1082) was 47.9 ± 22.1 years. Prevalence of onychocryptosis was 15.7% (n = 170) with a mean age of 54.1 ± 20.1 years and with a significantly higher affectation in women and people under 65. Prevalence of onychomycosis was 17.6% (n = 30), mean age 59.5 ± 20.5 years with greater involvement in women and people over 65 years. With regard to the questionnaire of habits, the footwear more employee was the closed, cordoned off and heel flat. The majority of the subject came to a podiatrist for the first time; walked approximately 1 hour and their daily activity made of foot with short displacements. CONCLUSIONS: A high prevalence of onychocryptosis and onychomycosis in people attending Podiatric services has been found. For its part using a type of flat or low heel and who does the care of toenails are shown as predictive variables of onychomycosis.

Nail alterations during pregnancy: a clinical study.

During pregnancy, cutaneous and appendageal alterations manifest and may cause concern in the subject. The nails may be affected by pregnancy. This study investigated the frequency and nature of nail changes occurring during pregnancy in 312 healthy, 18-40-year-old pregnant women in gestation weeks 16-40. After a routine obstetric examination at the obstetrics and gynecology clinic at the study institution, all subjects submitted to an examination of all fingernails and toenails. Only nail alterations that had developed during pregnancy were recorded. Any nail changes that had occurred before the start of gestation were not considered. Data were presented as percentages. The Shapiro-Wilk and chi-squared tests were used to make categorical comparisons. A P-value of < 0.05 was considered to indicate statistical significance. No nail pathologies were detected in 116 (37.2%) of the 312 subjects. The most commonly found nail change was leukonychia (24.4%). Ingrown toenail (9.0%) and onychoschizia (9.0%) represented the second most common nail changes. Rapid nail growth and subungual hyperkeratosis were observed in 6.7% and 4.2%, respectively, of subjects. When the alterations were evaluated according to gestational age, the most common nail pathology was leukonychia at both 14-28 weeks (16.3%) and 29-42 weeks (27.4%) of pregnancy. Leukonychia, onychoschizia, onycholysis, and brittle nail pathologies were frequently observed at 29-42 weeks of pregnancy (P = 0.047). A large proportion of nail changes that occur during pregnancy are benign and do not require treatment. However, these changes may cause significant cosmetic stress in women.

Onychomycosis treatment in the United States.

Onychomycosis is a common progressive infection of the nails that may result in remarkable morbidity. Although there are a variety of treatments available for fungal nail infections with different efficacy and safety profiles, there are limited reports on the ways in which physicians use these treatments or the frequency with which they prescribe them. In this retrospective study, major trends in the prescription and use of antifungal agents for treatment of onychomycosis in the United States were evaluated using data from the National Ambulatory Medical Care Survey. Results showed that current treatment and trends in use of drugs for onychomycosis in the United States are in accordance with recommendations in current guidelines.

Manejo de la onicocriptosis en atención primaria. caso clínico / Management of onychocryptosis in primary care: a clinical case

La onicocriptosis (uña encarnada) es una enfermedad ungueal de gran demanda en el servicio de atención primaria, molesta y limitante para los pacientes, con gran incidencia en el sexo masculino y en edades comprendidas entre la segunda y tercera décadas de la vida, de etiología indeterminada en la que intervienen una serie de factores tanto desencadenantes como predisponentes. El tratamiento depende del estadio en que se encuentre la uña encarnada e incluye desde procedimientos conservadores hasta intervenciones de cirugía menor que pueden ser realizadas por el médico de atención primaria en el centro de salud. Presentamos el caso clínico de un hombre de 25 años con onicocriptosis que no respondió a un manejo conservador y se realizó una extracción del extremo ungueal con matricectomía parcial (AU)

Onychocryptosis (ingrown toenail) is a condition commonly seen in Primary Care clinics. It is uncomfortable and restrictive for patients and has a high incidence in males between second and third decades of life. It is of unknown origin, with a number of predisposing triggering factors being involved. Treatment depends on the stage of the ingrown nail and the procedures may range from conservative to minor surgery that can be performed by the Primary Care physician in the health centre. We report the case of a 25-year onychocryptosis that did not respond to conservative management, and was extracted with partial matricectomy of the nail (AU)

Ingrown toenails.

Onychocryptosis or ingrown toenail is a very common pathology of the toenail unit, chiefly affecting adolescents and young adults. The ingrown toenail is responsible for disabling complaints like pain and difficulty in walking. It is associated with significant morbidity, hampering the quality of life as it interferes with sporting activities, school, or work. It principally occurs in the hallux. It is ascribed to poor trimming of the nails in combination with local pressure due to ill-fitting footwear, hyperhidrosis, poor foot hygiene and nail abnormalities. Pain, swelling and discharge are the main clinical features. Four stages of the condition have been described. Diagnosis is usually evident, but it should be differentiated from subungual exostosis and tumors of the nail bed. The current standard of care focuses on conservative treatment like the gutter splint technique in the initial stages, and in cases that are resistant to medical management or recurrent, surgical correction is the treatment of choice. There are various surgical techniques that are described in literature. Although there is no ideal technique, lateral nail plate avulsion with lateral matricectomy by phenol is commonly used and reported to be more effective in reducing recurrences. The aim of this review article is to focus on this common pathology of the nail, the various techniques employed in management and aid in the selection of treatment according to the stage and severity of the disease.

Treatment of ingrown toenails in the pediatric population.

BACKGROUND/PURPOSE: Nail avulsion plus chemical matrixectomy (CM) using NaOH as an alternative to surgical matrixectomy (SM) has recently been used in the treatment of ingrown toenails (IGTNs) in adults. No studies exist to dictate the most effective and safe treatment method in the pediatric population. METHODS: A retrospective review of pediatric IGTNs treated at 2 institutions for 6 years was done, looking at presentation, treatment modality, SM vs CM, and outcomes. RESULTS: Eight hundred forty-eight IGTNs in 518 patients were reviewed with an average age of 12.5 years. Twenty-three percent were felt to be infected at the time of presentation, and 34% were being treated with antibiotics within the preceding week of surgery. Seventy-nine percent of toenails underwent surgical management with the most common procedure being avulsion plus SM (65%), followed by avulsion plus CM (17%), and avulsion alone (14%). The overall recurrence rate after initial surgery was 19.5%. After adjusting for covariates, recurrence was associated with treatment by avulsion alone (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.5-4.7), avulsion plus CM (OR, 0.3; 95% CI, 0.1-0.7), and treatment with antibiotics within the week before surgery (OR, 0.5; 95% CI, 0.3-0.9; P = .017). The overall postoperative infection rate was 6% and was unrelated to presence of preoperative infection, use of antibiotics, or surgical treatment method. CONCLUSIONS: Ingrown toenails present a significant problem to youth and should be addressed in a diligent fashion. Chemical matrixectomy using NaOH is a safe and effective alternative to SM and maybe associated with a lower rate of recurrence, especially when use in conjunction with preoperative antibiotics.

Foot abnormalities in Canadian Aboriginal adolescents with Type 2 diabetes.

AIMS: To determine the profile of foot abnormalities in Canadian Aboriginal adolescents with Type 2 diabetes and the risk factors associated with these abnormalities. METHODS: Aboriginal adolescents with Type 2 diabetes underwent an interview, medical record review and foot examination in a tertiary care, paediatric hospital diabetes clinic and two geographically remote outreach clinics. The notes of 110 subjects were reviewed [mean age 15 +/- 3 years; mean duration of diabetes, 30 +/- 20 months; 71 (66%) female and 39 (34%) male] and 77 (70%) of the subjects were examined. RESULTS: Foot abnormalities were identified by either interview or notes review, and included poor toenail condition in 85 (77%), paronychia in 29 (26%), ingrowing toenails in 16 (15%) and neuropathic symptoms in 13 (12%) subjects. Foot abnormalities were identified by examination in many subjects, including poor toenail condition in 38 (49%), calluses in 34 (44%) and paronychia in 13 (17%) subjects. Eighteen (24%) of 75 subjects did not have running water in the home. Factors that significantly increased the presence of foot abnormalities included: foot care provided by a person other than self; absence of running water in the home; decreased frequency of bathing; and decreased frequency of nail clipping. A greater percentage of subjects living on a reservation or rural community had specialized consultations for retinal examination, footwear, or both than of those living in an urban or unknown residence. CONCLUSIONS: A high prevalence of foot abnormalities was noted in Aboriginal adolescents with Type 2 diabetes. These findings highlight the associated comorbidities in this population, emphasizing the need for early detection and intervention.

Formable acrylic treatment for ingrowing nail with gutter splint and sculptured nail.

BACKGROUND: The treatment of choice for an ingrowing nail has been surgical rather than nonsurgical. Yet, surgical treatments are far from successful, cause pain and patient apprehension, and leave disfigurement. Further, there is misunderstanding about the disease pathophysiology. OBJECTIVE: To demonstrate the benefits of a noninvasive method of treatment for an ingrowing nail using gutter splint and formable acrylics and to present a current understanding of the disease pathophysiology. METHODS: From a total of 541 cases of ingrowing nails treated, full follow-up data were obtained between January 1979 and March 2002. Formable acrylic treatments were carried out in 106 cases treated with acrylic-affixed gutter splint, 17 cases with sculptured nails, and 28 cases in which the two treatments were combined. These were then compared with 233 cases treated with adhesive tape-attached gutter splint and the remainder with other conservative modalities. RESULTS: Acrylic treatment with gutter splint and sculptured nail was found to be vastly superior to the other methods described, especially in the ability to firmly affix the gutter splint and sculptured nail for the extended period required for treatment. The treatment leads to a complete remission with almost instant alleviation of pain, with no disfigurement, while allowing for the resumption of daily activities. CONCLUSION: Conservative methods utilizing formable acrylics are highly beneficial in the treatment of an ingrowing nail and should be viewed as the first treatment option.

Segmental phenolization for the treatment of ingrowing toenails: a review of 6 years experience.

BACKGROUND: Ingrowing toenails are a common problem causing significant morbidity. Many of the procedures used for treating this painful condition cause considerable discomfort and have high failure rates. In recent years, phenol cauterization of the nail bed has been used increasingly. METHODS: A retrospective study was carried out of all patients treated by this method in the authors' clinic during the period January 1996 to December 2001. In this study, phenol cauterization is the standard form of treatment and 948 phenol cauterizations were carried out in 764 patients. RESULTS: There was no significant morbidity and the procedure was tolerated well by all patients. Overall recurrence was 4.3% (33 patients) after 18 months. All symptomatic recurrences were successfully treated by repeating phenol cauterization. CONCLUSIONS: Phenol cauterization compares favourably with other surgical ablation techniques for ingrowing toenails and may be the ablation procedure of choice of an ingrowing toenail.
