Phenol peels are an example of deep peels.3 Phenol, or carbolic acid (C6H5OH) (Figure 1), is a chemical agent that promotes facial rejuvenation.

Formulation and application The Baker-Gordon formula, still the most widely used in phenol peels, contains components that enhance the activity of phenol on the skin, such as croton oil and liquid soap (Figure 3). ,Q WKHLU DEVHQFH FHOOXODU UHJHQHUDWLRQ WHQGV WR EH OHVV HǡHFWLYH 4 &URWRQ RLO LQFUHDVHV ORFDO YDVFXODUL]DWLRQ HQKDQFLQJ WKH keratocoagulative action of phenol and promoting deeper cutaQHRXV LQǦOWUDWLRQ 8 Because it is highly toxic to the skin, it can cause edema and local erythema.

Contact time varies between 10 and 15 minutes per area.4,9 Studies show that phenol absorption through the skin can vary according to the pressure applied, the degree of friction, and exposure time. Fractionated application, with intervals between treated areas, is recommended to reduce systemic absorption and increase safety.

INTRODUCTION Cellulite is a highly prevalent condition in the female population, characterized by irregularities on the skin surface, and it DǡHFWV SULPDULO\ WKH WKLJKV DQG EXWWRFNV ,WV W\SLFDO FOLQLFDO SUHsentation consists of depressed and elevated skin lesions, especially in areas with a higher percentage of body fat and greater laxity.

Although it is highly prevalent among women, with some authors HVWLPDWLQJ UDWHV RI WR ZRUOGZLGH WKHVH ǦJXUHV DUH QRW EDsed on observational studies conducted at national or global levels.1,2 6SHFLǦFDOO\ LQ %UD]LO RQH UHJLRQDO VWXG\ DVVHVVHG WKH SUHvalence of cellulite among female adolescents in the state of São Paulo,3 but there are still no representative data on the prevalence of this condition among Brazilian women as a whole.

Given this gap in statistical knowledge regarding such a highly prevalent condition, this study intended to estimate the prevalence of cellulite among Brazilian women aged 12 years and older.

METHODS This is a cross-sectional study with a convenience sample, and the inclusion criteria were Brazilian women, literate, aged 12 years or older. Data collection was conducted through an online survey on the Google Forms platform, completed anonymously either by the participant directly or by her legal guardian, after signing the Informed Consent Form (or the Informed Assent Form for participants aged 12 to 18). The instrument was based on the validated Hexsel & Hexsel cellulite scale.4 The survey asked participants about their age, self-declared ethnicity, region of residence, place of residence (urban or rural), income range, weight, height, presence of cellulite in any body area, and the appearance of their lesions. All information was self-assessed.

The survey was distributed and publicized via the Internet. The survey link was shared by the researchers to their contact networks and, in each region of the country, sent to dermatologists through members of the Regional Chapters of the Brazilian Society of Dermatology. The survey was shared WKURXJK GLǡHUHQW UHJLRQDO JURXSV DV D VWUDWHJ\ WR PLWLJDWH WKH selection bias inherent to the study design and thereby ensure better representativeness of the Brazilian population. The data were collected from 04/14/2023 to 03/05/2025.5 The project was approved by the Hospital Moinhos de Vento de Porto Alegre Research Ethics Committee before its execution, and the researchers followed the principles of the Declaration of Helsinki and Good Clinical Practice.

This resulted in a minimum sample size of 385 participants for the primary objective of the study (analysis of cellulite prevalence).

For the statistical analysis of categorical variables (Tables 1 and 2), the chi-square test was used to evaluate the association between each variable (age, income, and race/ethnicity) and the presence or absence of cellulite.When conducting the chi-square test, if the association Tables and expected count Tables did not meet the prerequisite of expected frequencies equal to or JUHDWHU WKDQ )LVKHUÞV H[DFW WHVW ZDV DSSOLHG 7KH VLJQLǦFDQFH level for all tests was set at _ &UDP«UÞV 9 FRHǤFLHQW 9 was also calculated to assess the degree of association in Tables ODUJHU WKDQ ,Q VWDWLVWLFDOO\ VLJQLǦFDQW DVVRFLDWLRQV WKH DGjusted standardized residual, also known as the Z-residual, was calculated as a post-hoc interpretation method.

The prevalence of 100% in the population aged 70 to 79 years was also expected, since skin laxity is an aggravating factor for cellulite that worsens with aging, showing that the pathophysiological mechanisms responsible for the onset of cellulite tend to add up and intensify with advancing age.9-11 The study also found increased prevalence of cellulite in the 40 to

condition among Brazilian women.Traditionally, Caucasian ethnicity has been considered a risk factor for developing cellulite,12,13 but the data from this study do not support that hypothesis. Because Brazil is a highly mixed-race country, it is possible WKDW HWKQLF LQǧXHQFHV RQ WKH GHYHORSPHQW RI FHOOXOLWH SOD\ D VPDOOHU UROH DPRQJ %UD]LOLDQV ZLWK WKHLU HǡHFW RYHUZKHOPHG E\ factors such as overweight and age.

Many studies cite estimates of 80% to 90% prevalence for cellulite in the general female population,13,14 but the data that originated these estimates lack statistical grounding in prevalence studies with broad population coverage. Several articles mention these estimates without citing primary sources. The data from this study indicate an even higher overall prevalence of cellulite among Brazilian women, at 92.5%.

In this study, individuals with cellulite also had higher ERG\ ZHLJKW EXW QR VLJQLǦFDQW GLǡHUHQFHV ZHUH IRXQG LQ WHUPV of height or BMI compared with women without cellulite. A higher prevalence of cellulite among women with greater body weight was expected, given that the thickness of the subcutaQHRXV DGLSRVH WLVVXH LQǧXHQFHV KRZ WKH VNLQ VXUIDFH ORRNV 9,10 The mean BMI of participants with cellulite was 25.03, compaUHG ZLWK IRU SDUWLFLSDQWV ZLWKRXW FHOOXOLWH 7KLV GLǡHUHQFH ZDV QRW VLJQLǦFDQW OLNHO\ GXH WR WKH VWXG\ÞV ORZ VWDWLVWLFDO SRZHU since this was a secondary analysis variable that was not included in the sample size calculation.

Regarding statistical analyses of secondary data, subgroup analyses were not performed based on the type of cellulite lesion reported by participants (for example, depressed versus elevated lesions). Given the large number of analyses that would have been required (more than 60) and the considerable sample size of this study (614), there would have been a prohibitively high probability of type I errors (false positives), which would have made a reliable interpretation of the results impossible. Thus, the data were reported quantitatively and descriptively in Table 1, VWUDWLǦHG E\ DJH JURXS ,Q WKH VSHFLǦF FDVH RI FHOOXOLWH SUHYDlence by region, statistical tests were not performed because the

participants’ region of residence is only a confounding factor, LQGLUHFWO\ UHODWHG WR GHWHUPLQDQWV WKDW FRXOG DFWXDOO\ LQǧXHQFH the development of the condition, such as ethnicity, income, and weight.13 This study has limitations. The main one is the use of a convenience sampling rather than a randomized sample, which increases the risk of selection bias, partially mitigated by the inclusion of a large number of participants. Other biases inherent to the study methodology include the exclusive participation of literate women with Internet access, which reduces participation among socially vulnerable women, and the fact that cellulite was self-assessed. In addition, although all women could participate in the survey once they received the recruitment link, it is likely that women with cellulite were more inclined to respond, possibly leading this study to overestimate the prevalence of the condition.

Even though the distribution of participants in this study GRHV QRW UHǧHFW WKH %UD]LOLDQ SRSXODWLRQ LQ WHUPV RI LQFRPH DJH group, ethnicity, and state population, the sample included 467 Caucasian women of various income levels, aged 20 to 59 years, a number large enough to ensure internal validity for data analysis in this population subgroup. Self-assessment is also not a major limitation, since, as previously discussed, even young women seem able to diagnose the presence of cellulite with a reasonable degree of accuracy. Thus, even under a conservative interpretation, the data reported in this study have external validity for the subgroup of Caucasian women aged 20 to 59 years.

CONCLUSIONS Prevalence of cellulite is extremely high among Brazilian women, with an estimated rate of 92.5%. It is less common during adolescence (72%) and may reach values close to 100% in older age groups, above 70 years. It is more prevalent among women with higher body weight, and in the Brazilian population, self-declared ethnicity does not appear to be a risk or protective factor for the development of cellulite.

ABSTRACT The treatment of eyelid ectropion remains challenging. Surgical approaches are more widely used, but techniques using hyaluronic acid have shown increasing promise. This article describes a novel technique for hyaluronic acid injection through a cannula to correct severe cicatricial ectropion secondary to lamellar ichthyosis. Despite the need for further studies, the procedure proved to be safe and easily reproducible.

CASE PRESENTATION A 67-year-old woman had lamellar ichthyosis, bilateral ectropion, a left ocular prosthesis, and severely impaired vision in the right eye due to conjunctival and corneal exposure.

The goal was to use HA for tissue expansion to elevate the inferior tarsal border and facilitate eyelid closure, thereby minimizing ocular sequelae. For safety and to ensure a more homogeneous distribution of the acid, a cannula was preferred over a needle.

INTRODUCTION Pain and anxiety are fundamental aspects of the medical experience in the pediatric population, directly impacting treatment adherence, longitudinality of care, and the quality of care provided.1 Attention to these factors is critical to ensure a safer and more humanized environment,1 especially in invasive procedures such as skin biopsies.2 3DLQ LV GHǦQHG DV DQ XQSOHDVDQW VHQVRU\ DQG HPRWLRQDO experience associated with actual or potential physical harm.3 7KLV SHUFHSWLRQ RI SDLQ PD\ EH LQWHQVLǦHG E\ SV\FKRVRFLDO IDFtors such as anxiety, fear of the unknown, and a sense of vulnerability.4 Dermatological procedures, such as skin biopsies, often trigger an uncontrolled anxiety response, making it essential to DGRSW HǡHFWLYH VWUDWHJLHV WR UHGXFH VXǡHULQJ IRU ERWK FKLOGUHQ and their caregivers during medical procedures.5,6 Child mental health is a relevant factor to be considered, as it may compromise how the procedure is experienced and neJDWLYHO\ LQǧXHQFH ORQJLWXGLQDOLW\ RI FDUH ZLWKLQ WKH KHDOWK V\Vtem.7,8 Children who undergo painful procedures without adequate emotional support may develop fears and trauma related to medical visits, impairing adherence to necessary treatments.7,8 In addition, poorly managed pain may result in neurophysiological changes over time, increasing sensitivity to pain in future HYHQWV DQG DǡHFWLQJ WKH FKLOGÞV SHUFHSWLRQ RI KHDOWK FDUH 7,8 Therefore, strategies that aim at minimizing pain and anxiety are critical to promoting more humanized care and improving the child’s experience of caring for their own health.9 A multidisciplinary approach to pediatric pain management is a frequent subject in the literature, combining play-based interventions and nonpharmacological techniques.5,6,9 However, the development of structured protocols remains uncommon in WKH VFLHQWLǦF OLWHUDWXUH 7KH GHYHORSPHQW RI JXLGHOLQHV IRU SHdiatric dermatological procedures may represent an important contribution to improved clinical and emotional outcomes in children undergoing invasive procedures such as skin biopsies, DQG PD\ DOVR IRVWHU IXUWKHU UHVHDUFK LQ WKLV ǦHOG Several studies indicate that the combination of local anesthesia with nonpharmacological methods, together with GLVWUDFWLRQ WHFKQLTXHV DQG HPRWLRQDO VXSSRUW FDQ VLJQLǦFDQWO\ reduce pain and discomfort in children undergoing invasive procedures. The present study aimed to describe a local anesthesia protocol based on nonpharmacological therapies, using sensory distraction strategies and emotional support for skin biopsy procedures in children. The goal is to reduce pain perception, minimize anxiety, and improve cooperation among pediatric patients, thereby providing a more humanized experience.

METHODS A narrative literature review was conducted using the PubMed, Scopus, and SciELO databases. Articles published within the last 5 years were selected using the following English descriptors (MeSH terms): “pediatric OR children OR child OR neonatal,” “pain management,” and “non-pharmacology

anesthesia.” Inclusion criteria comprised clinical studies, systematic reviews, and meta-analyses addressing strategies for the management of pain and anxiety in children undergoing surgical procedures. Studies involving exclusively adult samples or addressing only pharmacological anesthesia without integration of non-pharmacological strategies were excluded. Figure 1 summarizes the results of the literature search.

Based on the data collected, a structured protocol for local anesthesia in children undergoing skin biopsies was developed, incorporating psychological and sensory approaches.

RESULTS 7KH SURWRFRO FRPSULVHV IRXU VWDJHV 7KH ǦUVW VWDJH FRQsists of providing clear, age-appropriate explanations about the procedure, addressing both the child and their caregivers.9,10,11 The guidance should be presented in a playful and accessible manner, using resources such as stories, dolls, drawings, or illustrated books, with the aim of demystifying the experience and reducing procedure-related anxiety. 9,10,11 The second stage involves encouraging parental support, allowing the caregiver to remain by the child’s side during the procedure and promoting physical and verbal contact as a strategy to enhance the sense of emotional security.12,13 The third stage involves the use of visual and auditory distraction strategies, such as electronic devices to watch videos or listen to stories, helping to shift their focus away from the procedure and consequently reduce stress.9,14,15 Finally, the fourth stage refers to the application of sensory modulation measures, including prior use of ice or vibratory devices at the biopsy site, with the goal of minimizing the perception of pain DVVRFLDWHG ZLWK LQǦOWUDWLRQ RI WKH ORFDO DQHVWKHWLF 16,17 The protocol is summarized in Figure 2.

In addition, the approach proposed in this study may contribute to improved family adherence to treatment, as a properly conducted procedure can strengthen the bond with the health care team and lower the resistance from both the child and their caregivers to medical care.13,25 This has a direct impact on the longitudinality of care, promoting more comprehensive clinical follow-up and potentially reducing the need for unnecessary interventions in the future.1,9 The combination of non-pharmacological techniques in pediatric pain management may also help build a more positive relationship between children and health care professionals.20 Children who experience a careful and humanized approach tend to develop greater trust in the medical team, which facilitates long-term care and promotes a more holistic approach to the health of patients and their caregivers across primary, secondary, and tertiary health care settings.27,28,29,30 CONCLUSION The combination of local ice or vibration with distracWLRQ VWUDWHJLHV DQG HPRWLRQDO VXSSRUW LV DQ HǡHFWLYH DOWHUQDWLYH for minimizing pain and anxiety in children undergoing skin biopsies.

Fat grafting provided a considerable improvement in facial contour, with the near-complete disappearance of depressions and irregularities.There was an initial resorption of 40% of the grafted fat, but the results were maintained after the second session, with a 5-month follow-up.

Areas such as the malar and orbital regions showed remarkable harmonization, reducing the appearance of hollow eyes and facial masculinization (Figures 3 and 4).

ABSTRACT Vermilionectomy is a surgical procedure for the partial or total removal of the vermilion border, used primarily for the treatment of actinic cheilitis. W-plasty has been considered superior to classic elliptical excision because it avoids linear scars and, therefore, lip retractions. However, the classic elliptical excision is still widely used. This article reports two cases treated with both techniques that achieved similar satisfactory aesthetic results.

RESUMO A vermelhectomia é um procedimento cirúrgico para a remoção parcial ou total do vermelhão labial, utilizado principalmente no tratamento da queilite actínica. A W-plastia tem sido considerada superior à técnica clássica de excisão elíptica por evitar uma cicatriz linear e, logo, retrações do lábio. No entanto, a excisão elíptica clássica ainda é amplamente utilizada. Este artigo relata dois casos tratados com ambas as técnicas que obtiveram resultados estéticos satisfatórios semelhantes.

INTRODUCTION Actinic cheilitis (AC) is a premalignant lesion resulting IURP FKURQLF VXQ H[SRVXUH WKDW DǡHFWV WKH YHUPLOLRQ RI WKH ORwer lip, characterized by erythema, atrophy, hyperkeratosis, and erosions.1 In treatment, it is essential to minimize the risk of malignant transformation while preserving local function and aesthetics.

Nonsurgical therapeutic options for AC include topical imiquimod, chemical cauterization with trichloroacetic acid (TCA), photodynamic therapy, topical diclofenac, and laser treatPHQWV ZLWK YDULDEOH HǤFDF\ 2 If clinical treatment of AC fails, one surgical option is vermilionectomy, which consists of partial or total removal of the lip vermilion. In the classic form of the procedure, the excision is elliptical or fusiform (spindle-shaped).3 In the W-plasty variant, the excision has a jagged outline.4 Some authors consider W-plasty superior to the classic technique because it avoids a linear scar and therefore lip retraction.4 However, the classic elliptical or fusiform excision remains widely used because it is technically easier to perform.3 This article reports two cases using both techniques (classic and W-plasty), with satisfactory aesthetic and functional outcomes and no recurrence of AC after 4 years of follow-up.

DISCUSSION Resolution of AC is important to prevent malignant transformation, regardless of the method used. However, when choosing vermilionectomy as the surgical technique, it is essential to avoid complications such as retraction, commissure deviation, microstomia, and hypochromia.1-4 In 1956, Kwapis and Gibson described vermilionectomy as the partial or total excision of the lip vermilion, with mucosal

advancement and its suture to the skin for closure of the defect.4 Elliptical or fusiform excision came to be known as the classic method (Figure 1A). In this technique, the scar is linear, increasing the risk of retraction.3,4 In 1989, Vozmediano described vermilionectomy using W-plasty.4 In this method, the excision has a jagged or serrated outline, and the resulting scar forms a broken line that distributes tension more evenly, reducing suture tension and lowering the likelihood of retraction (Figures 3A and 4B).

In 2011, Rossoe et al. compared 32 patients treated with the two vermilionectomy techniques (classic vs.W-plasty, 15 and 17 patients, respectively). In that study, W-plasty provided better aesthetic results.4 The advantage of the classic technique is that it is easier to perform. Primary linear closure reduces procedure time. In contrast, W-plasty requires interlocking the pointed projections with the corresponding recesses, which demands additional adjustments and extends the surgical time (Figure 5).3,4

The results of these techniques may depend on several factors, including age, comorbidities, smoking, postoperative care, and surgeon experience. It is important that dermatologic surgeons master both techniques so that they can be applied according to the needs of individual cases.4

In the two cases presented in this report, after 4 years of follow-up, similar results were observed, with no retraction, dyschromia, commissure deviation, or microstomia.

CONCLUSION Both vermilionectomy techniques, the classic method and W-plasty, can provide similar aesthetic and functional results in the treatment of AC. O

Dermatological examination revealed nail discoloration with a deep, T-shaped longitudinal ridge and thickening impinging on the nail bed at midline beneath the left thumbnail (Figure 1), resembling the keel of a ship (Figure 2). Total nail plate excision was planned to remove the painful ridge, along with the germinal matrix to prevent re-growth.

DISCUSSION Nails are ectodermal appendages that cover the dorsal aspects of the digits. They provide protection and integrity to WKH ǦQJHUWLS LQ DGGLWLRQ WR IDFLOLWDWLQJ ǦQH KDQG PRYHPHQWV Anatomical abnormalities of the nail unit may interfere with

these functions.3 Nail injuries are common in both industrial and domestic settings and can result in acute and chronic nail deformities.4 Proper knowledge and understanding of nail anatomy (Figure 8) are essential for the treatment of nail injuries.

Nail anatomy and growth Nails begin to develop at around 10 weeks of intrauteULQH OLIH IURP D NHUDWLQL]HG SODWH RQ WKH GRUVXP RI WKH ǦQJHU The perionychium includes the nail and its adjacent structures: hyponychium, nail bed, and nail folds. The eponychium is the proximal soft tissue on the dorsal aspect of the nail continuous with the dorsal skin.The white arc just distal to the eponychium is called the lunula. Beneath the nail plate lies the nail bed. The nail bed distal to the lunula is called the sterile matrix, and proximal to that is the germinal matrix. The distal attachment of the nail is the hyponychium, a pulp of keratinous mass rich in polymorphonuclear leukocytes and lymphocytes. The nail fold on either side is called the paronychium.

Approximately 90% of nail growth originates from the germinal matrix, while the sterile matrix contributes about 10% and provides adherence of the nail plate to the nail bed. Fingernails grow at a rate of 0.1 mm per day, faster than toenails.

Nail injuries and regrowth Nail growth ceases for approximately 21 days after trauma. An increase in growth is seen for the next 50 days, then a decrease for the following 30 days. Normal nail growth usually resumes 100 days after trauma. Permanent loss or deformity may occur when the germinal matrix, which is responsible for nail growth, is lost or damaged.2 Complete regrowth of an avulsed ǦQJHUQDLO RU WRHQDLO WDNHV PRQWKV DQG PRQWKV UHVpectively.3 Nail injuries include being crushed by machinery, road WUDǤF DFFLGHQWV VSRUWV LQMXULHV LDWURJHQLF FDXVHV VHOI LQǧLFWHG LQMXULHV VXFK DV QDLO ELWLQJ LQVHUWLRQ RI DUWLǦFLDO QDLOV LPSURSHU manicure, and direct damage to the nail matrix or nail bed, such as crushing, cutting, or avulsion.

The pathophysiology of traumatic ridged nails involves disruption in normal nail growth. The traumatic event directly injures the germinal matrix and nail bed, temporarily slowing or halting of nail growth.This can cause the formation of scar tissue, altering nail growth rates and creating ridges and lumps, as well as potentially complete nail loss or separation from the nail bed.

Damage to nail matrix and nail fold can result in characteristic post-traumatic defects such as split nails, nonadherent nails, or dull streaks.5 In the present case, an old trauma may have driven the germinal matrix into the subungual tissue. This embedded matrix, along with the normal matrix, may have continued to grow.

The embedded matrix would then have formed a nail plate structure beneath the nail, causing pain. A longitudinal ridge ran the whole length of the nail, extending from its deep aspect, akin to the keel of ship (Figure 2).

RESUMO Um tumor de colisão é uma condição rara que ocorre quando dois ou mais tumores cutâneos coexistem na mesma região anatômica. O objetivo deste estudo é apresentar o caso de um paciente do sexo masculino, 70 anos, com um tumor de colisão entre melanoma in situ e carcinoma basocelular de padrão nodular, abordando os aspectos clínicos, histológicos e terapêuticos ressaltando a importância do diagnóstico diferencial em neoplasias cutâneas complexas. Dado o número limitado de casos na literatura, é difícil prever a evolução biológica dos tumores de colisão. Assim, faz-se necessário o seguimento rigoroso dos pacientes e mais estudos que contribuam para o entendimento sobre essa condição.

Patients with a prior history of melanoma have a 10% risk of developing a second melanoma within 5 years.6 After a second episode, this likelihood increases to 30%.6 In this case report, a new BCC was diagnosed in the pectoral region during follow-up, with no RWKHU VXVSLFLRXV PHODQRF\WLF OHVLRQV LGHQWLǦHG WKURXJK HDUO\ 2025.
