A survey of the treatment and management of ingrown toenails by UK podiatrists: A cross-sectional survey.

BACKGROUND: Ingrown toenails are a common pathology. Although a range of conservative and surgical measures are widely used for this condition, little is known about their use in practice. This study explored current practice relating to the treatment or management of ingrown toenails by podiatrists in the UK. METHODS: A cross-sectional online survey (Qualtrics, Provo, UT, USA) conducted between March to June 2020 was distributed to practicing podiatrists treating or managing ingrown toenails in the UK. RESULTS: A total of 396 practicing podiatrists responded (60.1% based in the private sector). The majority (88.6%) performed nail surgery most commonly (54.3%) less than five a month. Nearly all (95%) only performed nail avulsion with or without chemical matrixectomy, universally using phenol (97.2%). Application time and number of applications varied but was most commonly applied three times (61.5%) for a total of 3 minutes (75%). Aftercare varied considerably between public and private sectors, with public sectors offering fewer follow-up appointments. CONCLUSIONS: Although there is a variation in clinical practice throughout the treatment pathway, almost all respondents offered nail avulsion with phenol matrixectomy, whereas very few provided incisional nail surgery. This data provides the most comprehensive description of how UK podiatrists conduct nail surgery for onychocryptosis.

Effects of a Training Course for Andalusian Podiatrists on Antibiotic Management in Ingrown Toenail Infections: A Pilot Study.

BACKGROUND: The use of antibiotics (ABs) for the prevention and management of infections has been widespread for decades and, at this time, AB resistance is a global health crisis. The available evidence highlights the need to reduce the prophylactic and therapeutic use of ABs to avoid associated risks. METHODS: A preliminary study with a total sample of 56 Andalusian (Spain) podiatrists was surveyed. The purpose of this study was to identify whether there were changes in prescription habits from a situation before a subsequent training course on AB indications for the management of infections associated with ingrown toenails. An ad hoc questionnaire of 15 items related to therapeutic and prophylactic prescriptions of ABs was developed for this purpose, and the evaluation was carried out before and after the training course. RESULTS: The responses obtained before and after training were compared. The training activity led to improvements in the prescription habits of the participants, producing significant changes in the prescription pattern of the professionals in 10 of the 15 items. CONCLUSIONS: The results of this preliminary study show that the podiatrists surveyed improved the rational use of systemic AB therapy in ingrown toenails infections.

Retronychia: the importance of proper footwear.

Retronychia is commonly underdiagnosed and exhibits classic features of proximal nail fold elevation and nail plate layering. Herein we summarize the literature and discuss cause, diagnosis, and treatment of this condition.

Assessment of Ingrown Toenails Treated with Nail Fold Cryotherapy in Adolescent Patients: An Observational Pilot Study.

BACKGROUND: Cryotherapy reduces pain by making some reversible functional changes in peripheral nerves. It has also been reported to have a positive effect on the regression of inflammation and granulation tissue. Few studies have evaluated the efficacy and safety of nail fold cryotherapy in ingrown toenails (IGTN) in adults, and there are no studies in the pediatric population. We aimed to evaluate the clinical efficacy of cryotherapy applied to the nail fold in juvenile IGTN. METHODS: This study was conducted in adolescent patients aged 12 to 16 years with unilateral juvenile IGTN. Liquid nitrogen was sprayed into the nail fold for 10 to 15 seconds with a double freeze-thaw cycle. The effectiveness of cryotherapy was interpreted by the clinician's decision, the improvement in visual analogue scale score, Children's Dermatology Life Quality Index score, and granulation tissue. RESULTS: According to the physician, good efficacy was achieved in 91.7% of patients (n = 22 of 24). We found that 54.5% of them (n = 12 of 22) were still in remission after 6 months. Rates of complete regression in granulation tissue were pronouncedly less in sizes larger than 5 mm (≤5 mm, 55.6%; >5 mm, 16.7%). However, adequate symptomatic relief was observed in 83.3% of stage 3 patients, even if complete granulation tissue response was not achieved yet. Significant improvements in visual analogue scale and the Children's Dermatology Life Quality Index scores were observed after cryotherapy (P < .05). CONCLUSIONS: Nail fold cryotherapy is a useful alternative among conservative methods because of its rapid and high efficiency (91.7%), especially in mild to moderate cases, despite the high recurrence rates (45.5%) in juvenile IGTN.

Management of ingrowing nail.

For decades, there has been debate about the cause of ingrown nail: is the nail plate or the periungual tissue at fault? There is no consensus and management relies on case-by-case analysis followed by tailored treatment. Conservative treatment should be attempted in children when the cause is transient (e.g., poor clipping) or the patient refuses surgery. Surgical treatments rely on two main approaches: either narrowing the nail plate, or debulking the soft tissue. It is up to the surgeon to select the most appropriate approach in each case. All procedures discussed in this chapter have high cure rates as long as they are properly performed. As with all surgical procedures, they are operator-dependent. Chemical cautery is the easiest and most versatile technique that may help in almost all instances for lateral ingrowth. For distal ingrowth and very hypertrophic and exuberant lateral folds, debulking with primary or secondary healing is most effective.

Retronychia in children: A case series.

BACKGROUND: Retronychia is characterized by proximal ingrowing of the nail plate into the proximal nail fold. It is always associated with the presence of two or more overlapping nail plates under the proximal nail fold, clinical signs of chronic proximal paronychia refractory to antimicrobial treatment, and a yellowish nail that does not grow. It mainly affects young female adults, with less than 30 pediatric cases described in the literature so far. METHODS: Retrospective and observational study of patients between 0 and 18 years with a clinical and/or ultrasound diagnosis of retronychia attending a pediatric dermatology service between December 2020 and January 2022. RESULTS: We identified 9 patients with retronychia, 7 girls and 2 boys. In all cases, the hallux nails were affected with 5 unilateral and 4 bilateral cases. On physical examination we observed the following signs: thickened and opaque nail plate (one patient), yellowish nail plate (7 patients), double nail plate (6 patients), and erythema with edema, pain, and suppuration of the proximal nail fold (7 patients). Ultrasound was performed in 7 patients and specific findings of retronychia were found in 5 of them. All patients received topical treatment and were referred for the appropriate surgical treatment. To date, only one patient underwent nail avulsion, which was followed by complete recovery. CONCLUSIONS: Retronychia is underdiagnosed, particularly in the pediatric population. We present a series of 9 cases of retronychia in children, with clinical and ultrasonographic findings consistent with those of adults. We emphasize the importance of recognizing this entity, which will allow early and adequate treatment.

[Conservative treatment options for unguis incarnatus]. / Conservatieve behandelopties bij unguis incarnatus.

Unguis incarnatus (ingrown toenail) is a common problem in daily practice. Persons with unguis incarnatus stage two and three are often referred for surgical partial nail excision, however conservative treatment or minimal-invasive alternatives exist. In the latest Dutch guideline for ingrown toenails, there is minimal attention to these alternatives. A podiatrist can do a spiculectomy and places a bilateral orthonyxia (nail brace) or tamponnade afterwards. This treatment option was studied in a prospective cohort study in 88 persons with high risk for wound healing problems and was found to be a safe and effective treatment option. In this clinical lesson we discuss three casus and their treatment options including minimal-invasive treatments. Guidance of the nail growth needs more attention after procedures just like adequate nail clipping advices to prevent for recurrences. Both are not announced in the latest Dutch guideline.

Comparative study between nail retraining with gauze bandaging and the nail remodeling with acrylics as a conservative treatment for stage I and IIa onychocryptosis.

OBJECTIVE: Onychocryptosis is one of the most prevalent onychopathies, being a frequent reason for consultation in podiatric clinical practice. Conservative treatments are the first therapeutic choice, with nail remodeling using clotrimazole gel emerging as an alternative, although its medium-term effectiveness is unknown. The objective of this study was therefore to compare the efficacy of the technique of nail retraining using gauze bandaging with that of nail remodeling for the conservative treatment of stage I and IIA onychocryptosis. METHODS: An analytical, randomized clinical trial study was performed following a longitudinal and prospective design. A sample was selected of 20 subjects presenting stage I and IIA onychocryptosis. Of these, 10 cases formed the group of nail retraining using gauze bandaging, and the other 10 the nail remodeling group. The presence of recurrence in a 3-month period was evaluated. RESULTS: Before the intervention, the patients in the retraining group presented pain of 6.7 ± 1.9 vs. 6.8 ± 1.6 in the remodeling group, with no significant difference between the two (p = 0.900). After the 3-month follow-up period, seven of the retraining group patients presented recurrence of onychocryptosis vs. only one in the remodeling group. CONCLUSION: The technique of nail remodeling has a lower recurrence rate than that of nail retraining with gauze bandaging, with the pain, inflammation, and infection reported being less, and with greater patient satisfaction.

Retrospective Evaluation of Ingrown Toenails in a Tertiary Reference Center.

BACKGROUND: We evaluated the clinical characteristics of ingrown toenails in one of the biggest reference centers in Turkey. METHODS: This retrospective cohort study was conducted on patients admitted to Ufuk University Hospital with ingrown toenail between January 1, 2014, and December 31, 2019. Clinical characterstics and demographic features of all of the participants were evaluated, and then the study population was divided into two groups: group 1 (patients ≤20 years old) and group 2 (patients >20 years old). These groups were compared in terms of clinical findings. RESULTS: Disease duration, body mass index, rate of medications for chronic diseases, and rate of joint diseases were significantly higher in group 2. Rates of hyperhidrosis and sudden weight gain were significantly higher in group 1 (P < .05). Severity of ingrown toenail was significantly different between groups (P = .006). Stage 1 was the most common stage in both groups, and rate of stage 3 was higher in group 1. Onycoshisis and was more common in group 1, and nail thickening was more common in group 2 (P < .05). Nail wire and aluminum chloride were the most common treatment modalities in groups 2 and 1, respectively (P < .05). Periungual edema, presence of pus, hypertrophy, and granulation were more common in group 1 (P < .05). Thin nail plate was more common in group 1, and normal and thick nail nail plates were more common in group 2 (P < .05). CONCLUSIONS: Clinical characteristics of ingrown toenail vary between younger and older populations. Thus, an individualized approach is preferred in the management of ingrown toenail for different age groups.

Risk factors for poorly controlled and recurrence-prone ingrown toenails treated with nail braces: A retrospective observational study of 238 cases.

Background Nail braces are reportedly effective for treating both acute inflamed and chronic dystrophic type ingrown toenails. Aims In this study, risk factors for poorly controlled and recurrence-prone ingrown toenails treated with nail braces were identified. Methods We performed a retrospective study on patients with ingrown toenails between June 1, 2015, and May 31, 2018. The last follow-up date was January 31, 2019. Multivariate logistic regression was performed to evaluate the possible factors associated with poorly controlled status (ongoing paronychia during treatment) and recurrence. Results There were 120 (244 sides) and 118 patients (167 sides) with chronic dystrophic and acute inflamed type ingrown toenails, respectively. The mean treatment duration and follow-up period were 161.2 ± 98.3 days and 432.7 ± 320.9 days, respectively. Poor control and recurrence were seen in 7.3% (17/232) and 12.2% (27/221) of the patients, respectively. In the multivariate analysis, acute inflamed ingrown toenails, previous nail avulsion, proximal nail fold hypertrophy and more than one affected side remained significantly associated with poorly controlled ingrown toenails. Foot bone deformity was significantly associated with recurrence. Limitations This study was a retrospective study so that confounding factors such as comorbidities, body mass index, accompanying nail changes and lifestyle could not be evaluated. Conclusion Several risk factors related to poor control and recurrence were identified. Patients could therefore benefit from more suitable treatment plans with reasonable expectation.

Treatment of retronychia: A systematic review and suggested treatment algorithm.

Retronychia is an inflammatory disorder typical of the great toes characterized by arrested nail growth, ingrowth of the nail plate into the proximal nail fold and paronychia. There is no standardized treatment for retronychia, and its management should be weighed based on the severity stage, treatment modality, and clinical outcome. In this paper, a systematic review of the literature was performed to assess all published data regarding the treatment of retronychia. A total of 231 patients from 24 studies were included in the analysis. Conservative management was adopted in mild-intermediate forms, consisting of medical (topical or intralesional high-potency corticosteroids) and podiatric treatment (taping, clipping back the onycholytic plate, orthosis), leading to a global cure rate of 41.2%, with no reported side effects. Non-conservative management, that is, chemical or surgical avulsion of the nail plate, proved resolutive in 71.2% of cases. Surgical avulsion of the nail plate produced the highest cure rate (78.2%), but was burdened by 9.6% of long-term sequelae, mainly nail dystrophies. A decision-making algorithm was designed to give clinicians treatment indications based on the severity stage of retronychia, treatment invasiveness, and possible clinical outcomes.

[Guideline 'Ingrown toenails']. / Richtlijn 'Ingegroeide teennagel'.

Ingrown toenails (also called unguis incarnatus) are a common problem in the general population. In early 2020, the medical specialists' guideline "Ingrown toenail" was published in which the various treatment options are compared. Conservative treatment can be considered for stage I ingrown toenails. In stage II-III ingrown toenails and failing conservative treatment, operative treatment is recommended consisting of partial nail extraction from the ingrown nail edge in combination with destruction of the corresponding part of the matrix. There doesn't seem to be any reason to deviate from the advice in the case of a recurring ingrown toenail or an ingrown toenail in a patient with expected wound healing problems. A detailed elaboration of the guideline, which also contains a step-by-step operative approach, can be found on the Guidelines database (https://richtlijnendatabase.nl/).

How effective is cryotherapy applied to the nail fold in ingrown toenails?

INTRODUCTION: There are only two publications in Pubmed on the effectiveness of cryotherapy in ingrown toenails, and they present conflicting results. We aimed to clarify the clinical effectiveness of cryotherapy in onychocryptosis. METHODS: This study retrospectively examined the visual analogue scale (VAS), dermatological life quality index (DLQI), other medical records, and photographs taken before each cryotherapy session and 6-month follow-up in 59 adult patients with ingrown toenails that underwent cryotherapy with a 3-week interval. Cryotherapy effectiveness was assessed by the clinicians' decisions, improvements in VAS and DLQI scores, and granulation tissue. Other factors related to effectiveness and recurrence were also investigated. RESULTS: After excluding approximately 20% of patients, for whom the treatment was not effective, this study revealed that recurrence rates in unilateral and bilateral onychocryptosis were 34.2% and 88.9%, respectively, 6 months after treatment. In patients that responded to the treatment, about 75 to 80% had excellent symptomatic responses. Excellent symptomatic responses were maintained in about 80% of patients in remission. We found that foot or toe deformity was associated with treatment ineffectiveness (p = 0.019). Age younger than 20 years and bilateral ingrown toenails were also related to recurrence (p = 0.042 and 0.003, respectively). CONCLUSIONS: Cryotherapy can be used to greatly and consistently improve the DLQI in suitable ingrown toenails.
