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. The outcomes measured were the incidence of postoperative bleeding and infection, recovery time, patient satisfaction, and recurrence rate 6 months after surgery. Results  Of the 130 patients included, 59 (45.4%) underwent excision and curetting of the nail matrix (group 1) and 71 (54.6%) underwent excision, curetting, and electrocauterization of the nail matrix (group 2). The postoperative infection rates were 20.3 and 4.2% in the first and second groups, respectively ( p  = 0.004). Patient satisfaction was 76.3% among the first group, while 91.5% of patients in the second group were satisfied with the results of surgery. Six months postoperatively, recurrence rates were 25.4 and 4.2% in the first and second groups, respectively ( p  = 0.001). Conclusion  Wedge excision and curettage, followed by electrocauterization of the ingrown toenail is a safe treatment modality with a high success rate, that is evident by a lower recurrence rate, and greater patient satisfaction, with no effect on postoperative pain score or recovery time.

UNASSIGNED: We aimed to identify the frequency and risk factors of pre-ulcerative lesions of foot in Japanese individuals with diabetes.
UNASSIGNED: This was a single-center cross-sectional observational study. We conducted a questionnaire survey of 5029 individuals with diabetes (mean age 63 years; 2185 women; 1015 individuals with type 1 diabetes and 4014 individuals with type 2 diabetes) who (a) participated in the Diabetes Study from the Center of Tokyo Women\'s Medical University: DIACET 2018, and (b) responded to the presence of pre-ulcerative lesions of foot. A pre-ulcerative lesions of foot was defined as a calluses, ingrown nails, or symptoms of fungal infection. The associations between pre-ulcerative lesions of foot and commonly available clinical information were examined using the logistic regression analysis.
UNASSIGNED: 412 of 1015 (40.6%) individuals with type 1 diabetes and 1585 of 4014 (39.5%) individuals with type 2 diabetes reported having any type of pre-ulcerative lesions of foot. The frequency of calluses, ingrown nails, and symptoms of fungal infection, respectively, were 16.8%, 15.8%, and 21.9% in type 1 diabetes and 10.5%, 18.5%, and 24.7% in type 2 diabetes. In the separate analysis by type of diabetes, common risk factors found to be significantly correlated with pre-ulcerative lesions of foot were female gender, numbness in the feet and foot deformation.
UNASSIGNED: Proactive foot screening by health care professionals was considered important, especially in individuals with type 1 and type 2 diabetes with advanced complications and foot deformation.

BACKGROUND: Although partial onychectomy with chemical matricectomy has been described asthe treatment of choice, there is sparse evidence in the literature regarding the use of silvernitrate for matricectomy. Our aim is to describe the effectiveness of silver nitrate for matrixcauterization after partial onychectomy.
METHODS: A prospective observational study was performed on patients with ingrown toenailsstage 2-3 who underwent partial onychectomy with silver nitrate chemical matricectomy during 2018-2019 in our institution. All patients were evaluated in the outpatient clinic on the 7th and 30th post-operative day and a telephone evaluation was performed every 6 months afterthe surgical procedure to date.
RESULTS: One hundred and twenty-three patients, who underwent 231 partial onychectomies with silver nitrate chemical matricectomy were included, with a median follow-up of 21 months (interquartile range, 12-29). The procedure had an effectiveness of 95.3%, with only 11 recur-rences (4.7%) reported so far on follow-up. Postoperative infections were observed in 4 patients (1.7%). Adverse effects, such as pain and postoperative drainage, were irrelevant in mostpatients.
CONCLUSIONS: Silver nitrate matricectomy after partial onychectomy is an effective and safealternative for the treatment of ingrown toenail in children, with scarce postoperative morbidityand low recurrence rate.

BACKGROUND: Partial onychectomy with chemical matrixectomy is considered the gold standard treatment for stage II-III ingrown toenails (IT). However, there are scarce reports describing the use of silver nitrate in IT management in adolescents. Our aim is to analyze the effectiveness of matrix ablation with silver nitrate and compare it with partial onychectomy by electrocautery.
METHODS: A retrospective study of adolescent patients with stage II-III IT was performed. Those who underwent electrocautery matricectomy in a major outpatient surgical center (Group A) and those who were treated with silver nitrate at an outpatient clinic (Group B) were compared. Efficacy was determined by recurrence and postoperative infection rates.
RESULTS: Two hundred and nine patients were included (86 group A; 123 group B), with a total of 382 partial onychectomies (151 group A; 231 group B). Group B patients exhibited a lower recurrence rate (4.7%) when compared to group A (11.2%, p = .02), and had a lower postoperative infection rate (4.0% group A vs. 1.7% group B; p = .18), although not statistically significant.
CONCLUSIONS: Silver nitrate chemical matricectomy after partial onychectomy is an effective treatment for IT in adolescents, with few postoperative complications and low recurrence rate. Therefore, it should be considered as a possible alternative to electrocautery matricectomy.

OBJECTIVE: This study aimed to compare the effects of the Winograd and modified Winograd methods for nail bed suturing on clinical outcomes in patients with nail ingrown.
METHODS: In total, 45 patients who underwent surgery for ingrown toenails between December 2019 and December 2020 were randomised retrospectively. In this study, different methods applied by the authors were studied, and the methods applied by each author were divided into two separate groups. All patients had partial germinal matrix and nail bed excisions. Thirty (53.6%) of the nails were dressed in gauze, leaving the excised area of ​​the nail unsutured (group 1). Then, the remaining 26 nails (group 2) were sutured with the mattress suturing technique to ensure that the skin was under the nail. Clinical outcomes, visual analogue scale (VAS) scores, and verbal satisfaction status were statistically evaluated.
RESULTS: In our study, 56 nails of 45 patients were evaluated retrospectively. The patients were followed up for an average of 13 (10-19) months. The mean age was 27.13 (15--48) years. In total, 31 (68.9%) of the patients were men, and 14 (31.1%) were women. The incidence of postoperative bleeding and granulation tissue development decreased in the sutured group. In group 1, the development of hypertrophic granulation tissue after surgery had a significantly negative impact on VAS score and recovery time. In the sutured group, patients returned to work or performed activities of daily living for a shorter period. Approximately 95% of patients were satisfied or extremely satisfied.
CONCLUSIONS: Partial matrix excision using the appropriate suturing technique is associated with a fast recovery, low recurrence rate, high patient satisfaction, and earlier return to work activities of daily life among patients treated for ingrown toenails.

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.

The aim of this study was to compare the result of electrocauterization and curettage, which can be done with basic instruments. Patients with ingrown nail were randomized to 2 groups. In the first group, nail matrix was removed by curettage, and the second group, nail matrix was removed by electrocautery. A total of 61 patients were enrolled; 32 patients were operated by curettage, and 29 patients were operated by electrocautery. Wound infections, as early complication, were found in 15.6% (5/32) of the curettage group, 10.3% (3/29) of the electrocautery group patients each (P = .710). Nonrecurrence was observed in 93.8% (30/32) and 86.2% (25/29) of the curettage and electrocautery groups, respectively, (lower limit of 1-sided 90% confidence interval = -2.3% > -15% [noninferiority margin]). To remove nail matrix, the curettage is effective as well as the electrocauterization. Further study is required to determine the differences between the procedures.
