Abstract
PURPOSE OF REVIEW Congenital melanocytic nevi (CMN) and acquired nevi are prevalent in pediatric populations, with distinct characteristics and management considerations. This chapter aims to equip pediatricians with knowledge to discern between benign and high-risk nevi, facilitating appropriate referrals and management within primary care settings. Risk factors associated with malignant melanoma (MM) underscore the importance of vigilant monitoring and early referral to dermatology for suspicious lesions. RECENT FINDINGS Recent findings highlight the variability in CMN presentation and the evolving diagnostic strategies, emphasizing the need for multidisciplinary approaches to optimize patient outcomes. SUMMARY Management of CMN involves tailored surveillance and intervention strategies, with an emphasis on early identification of high-risk features for MM and neurocutaneous melanosis (NCM). Pediatricians play a crucial role in advocating for sun protection practices and facilitating timely referrals, thereby contributing to the overall well being of pediatric patients with nevi.

Goel A, Goel A. Optimal timing for plastic surgical procedures for common congenital anomalies: A review. World J Clin Pediatr 2024; 13:90583. [PMID: 38947997 PMCID: PMC11212758 DOI: 10.5409/wjcp.v13.i2.90583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 04/04/2024] [Accepted: 04/11/2024] [Indexed: 06/07/2024] Open
Abstract
Apart from listening to the cry of a healthy newborn, it is the declaration by the attending paediatrician in the labour room that the child is normal which brings utmost joy to parents. The global incidence of children born with congenital anomalies has been reported to be 3%-6% with more than 90% of these occurring in low- and middle-income group countries. The exact percentages/total numbers of children requiring surgical treatment cannot be estimated for several reasons. These children are operated under several surgical disciplines, viz, paediatric-, plastic reconstructive, neuro-, cardiothoracic-, orthopaedic surgery etc. These conditions may be life-threatening, e.g., trachea-oesophageal fistula, critical pulmonary stenosis, etc. and require immediate surgical intervention. Some, e.g., hydrocephalus, may need intervention as soon as the patient is fit for surgery. Some, e.g., patent ductus arteriosus need 'wait and watch' policy up to a certain age in the hope of spontaneous recovery. Another extremely important category is that of patients where the operative intervention is done based on their age. Almost all the congenital anomalies coming under care of a plastic surgeon are operated as elective surgery (many as multiple stages of correction) at appropriate ages. There are advantages and disadvantages of intervention at different ages. In this article, we present a review of optimal timings, along with reasoning, for surgery of many of the common congenital anomalies which are treated by plastic surgeons. Obstetricians, paediatricians and general practitioners/family physicians, who most often are the first ones to come across such children, must know to guide the parents appropriately and convincingly impress upon the them as to why their child should not be operated immediately and also the consequences of too soon or too late.

Abstract
Adolescents with the rare birthmarks congenital melanocytic naevi (CMN) experience physical and psychosocial challenges, many of which stem from looking different from the 'norm'. However, some adjust and have positive experiences. Understanding the lived experiences of adolescents who have adjusted to CMN can provide a holistic picture of adjustment and inform the development of support and interventions for others with the condition. Open, participant-driven photo-elicitation interviews were conducted with four White females (15-17 years) who self-identified as having adjusted to CMN. Participants chose five photographs which were used to guide the interviews (47-80 min). Interpretative phenomenological analysis (IPA) was used to analyse the transcribed interview data. Three superordinate themes were identified: 'Accepting My 'True' Self' (1), 'I am Not Alone in This' (2), and 'Developing as a Person' (3). The themes related to accepting CMN as part of their identity, developing a positive body image (e.g., body appreciation, broad conceptualisations of beauty, body image flexibility), feeling supported and accepted by family, friends, and others with CMN, and developing adaptive coping skills. Findings suggest positive body image may be important for adjustment and can be determined by an individual. The benefits of using photo-elicitation within appearance research are discussed.

Abstract
Congenital melanocytic nevi (CMN) carry an increased risk of melanoma and may be disfiguring, and consensus regarding treatment recommendations is lacking. While clinical monitoring is the standard of care, many caregivers are interested in its removal to prevent psychosocial burden or to decrease risk. Although melanoma can occur regardless of CMN removal, there are a variety of treatments that may offer improved cosmesis or local symptom control, including surgical excision, laser therapy, and other superficially destructive techniques. Regardless of the selected management, these patients are monitored for ongoing melanoma risk. An extensive discussion with families regarding the risks and benefits of observation versus active intervention is essential. To facilitate these discussions, we herein summarize current CMN management strategies and considerations.

Abstract
A pediatric dermatology expert working group performed a narrative review to describe care related to congenital melanocytic nevi (CMN) in neonates and infants. There are no published guidelines for most aspects of care, including routine skin care and visit intervals. Few guidelines exist for surgical management; newer recommendations favor conservative practice. Emerging evidence contributes to recommendations for screening MRI to evaluate for neural melanosis and related central nervous system complications, however, more research is needed. Risk for melanoma is generally low, but those with large, giant, or multiple CMN have a higher risk. Multidisciplinary care, with a focus on family and patient preferences, is of paramount importance. Without standardized screening and management guidelines, questions abound regarding appropriate physical examination intervals, potential treatment including full or partial excision, timing and frequency of imaging, melanoma risk, and assessment for neural melanosis. This review highlights the current state of knowledge concerning care of patients with CMN, reveals gaps in the literature surrounding skin care, and provides management recommendations. We additionally discuss cutaneous complications of CMN, such as pruritus, hypertrichosis, and wound healing. Resources and references for families and providers can help patients navigate this sometimes challenging diagnosis. Finally, we contribute expert care recommendations to the current body of literature as a foundation for the development of future, more comprehensive care guidelines.

Abstract
Melanocytic nevi are congenital or acquired benign melanocytic neoplasms. The reason for the appearance of melanocytic nevi is not precisely known. Melanocytic nevi frequently occur in children, constituting a common reason for consultation in pediatric dermatology clinics. In our experience, many parents and caregivers present doubts and fears based more on popular beliefs than on data with valid scientific evidence. This review answers their frequently asked questions, such as the risk of malignancy, the importance of nevi location, the warning signs of malignant transformation, best prevention strategies, and optimal management, based on the most recent scientific evidence available.

Abstract
Congenital pigmentary anomalies may be evident at birth or soon after, with some birthmarks becoming apparent later in infancy or early childhood. It is important to recognize various pigmentary anomalies in the neonate, most of which are benign but a subset of which are associated with cutaneous morbidity or systemic ramifications and require further evaluation. This review will focus on pigmentary mosaicism, congenital melanocytic nevi, nevus spilus, dermal melanocytosis, and pigmentary anomalies associated with neurofibromatosis type 1 (café au lait spots, freckling, plexiform neurofibromas, nevus anemicus), tuberous sclerosis (hypomelanotic macules), and incontinentia pigmenti.

Abstract
When congenital melanocytic nevus (CMN) is in the maxillofacial region, a safer, more effective and fewer side-effects treatment is needed for patients with high requirement for appearance. The objective of this study was to investigate the effectiveness of radiofrequency thermal ablation (RFA) for CMN in the maxillofacial region. We reviewed 21 patients treated with RFA for CMN followed by a blinded retrospective analysis of serial photographs taken during the course of their therapy. Questionnaires were used to evaluate perceived therapeutic response and complications of this treatment. Most CMNs stopped growing, faded in color and became smaller. Reduction in size of 90% to 100% was obtained in two patients (10%), 75% to 90% in six patients (29%), 50% to 75% in two patients (10%), <50% in eight patients (38%), and three had no reduction (13%). Clear effect of clinical response score was obtained in two patients (10%), excellent in four patients (19%), good in 14 patients (67%), and fair in one patient (4%). No serious complication, severe hypertrophic scarring, and evidence of recurrence was observed in any case. Percutaneous RFA, as a minimally invasive and safe treatment, may provide an alternative treatment for maxillofacial CMN.

Abstract
The possible transformation of a giant congenital melanocytic nevi (GCMN) in malignant melanoma estimated from 0.05% to 40% depend on the size of the lesions. Many are the surgical procedures proposed, including: full or partial-thickness excisions, dermabrasion, curettage in the first weeks of life and laser treatment. The curettage technique has been proposed in the literature for the treatment of GCMN in the first few weeks of life and defined as a relatively atraumatic surgery procedure without general complications. The authors report the first case in the literature of embolization due to use of subcutaneous peroxide infiltration before a tardive curettage procedure in a newborn case of GCMN resulting in spastic quadriplegia with dystonic reaction. Consequently, a lawsuit, due to this medical malpractice, has been opened.

Abstract
PURPOSE The role of surgery in the management of congenital melanocytic nevi (CMN) is controversial. Data on surgical outcomes and predictors of satisfaction remain scarce. METHODS An online survey was employed following worldwide recruitment of youth aged 14-25 years (n = 44) and parents of children ≤ 18 years (n = 249) with CMN to query patterns of treatment and satisfaction with and opinions about the benefits of surgery. RESULTS In proxy-reports, 121 of 249 (49%) and in self-reports 30 of 44 (75%) participants underwent CMN excision. The most common reasons for surgery were psychosocial determinants, aesthetic improvement, and melanoma risk reduction. The overall satisfaction with surgical management was good, although no predictors for satisfaction could be identified. Higher current age of the child was found to predict decision regret in proxy-reports. Most participants indicated that having a scar is more socially acceptable than a CMN. Opinions differed on whether surgery should be deferred until the child is old enough to be involved in the decision-making process. CONCLUSIONS Whether and when to perform surgery in children with CMN is a multifaceted question. Awareness of common concerns as well as risks and benefits of surgery are essential to ensure critical reflection and balanced decision-making.

Abstract
BACKGROUND Children with congenital melanocytic nevi (CMN) were historically managed with surgical removal to lower the risk of malignant transformation. The evolving literature over the last decade has indicated a significantly lower risk than previously estimated. Indications for excision currently revolve around aesthetic and psychosocial concerns. This study describes and evaluates the perspectives and expectations of patients and families referred to a pediatric plastic surgery clinic on CMN management. METHOD A two-part questionnaire was administered before and after an initial clinic appointment to evaluate patient and family concerns of lesion growth, risk of malignancy, treatment expectations, and stigmatization. RESULTS Thirty questionnaires were completed for 11 male and 19 female patients, mean age 9.2 years (1-25). Referring doctors (majority dermatologists) were rarely concerned about malignancy (8%), but parents listed it as a top reason for wanting the CMN removed (37%) and the most common expectation for the visit followed by information about surgical options and outcome. Before the clinic, 93% were at least "slightly" worried about CMN growth and 96% about malignancy, whereas 63% and 72%, respectively, after the clinic. CONCLUSIONS Families want information about surgical excision and are concerned about malignancy, indicating lingering misinformation or misconception about melanoma risk. For the majority, CMN removal remains at least slightly important, presumably for aesthetic reasons and remaining concern about malignancy. Involved health care professionals should assure reliable and coherent patient information about MM risk, indications for surgery and expected outcome to best support families' decision-making.

Abstract
BACKGROUND Congenital giant melanocytic nevus on the face is a challenging condition, especially in the pediatric population. It can produce significant cosmetic deformity with negative psychosocial effects in pediatric patients even after treatment. The objective of this study was to report aesthetic and psychosocial results in the management of congenital melanocytic nevus on the face using multiple reexpansion. METHODS Data of 6 patients with congenital melanocytic nevus on the face who underwent excision and multiple reexpansion at our center from September 2004 to August 2017, were retrospectively reviewed. To evaluate aesthetic outcomes, preoperative and final photographs of each patient were reviewed by 3 other plastic surgeons and 4 laypersons. For comparison, 6 other patients who were treated with conventional surgery during the same period were reviewed. After final reconstruction surgery, the authors surveyed patients' satisfaction via telephone. RESULTS Six patients were followed up for an average of 87.66 months (range, 55-123 months). The mean number of tissue expander insertions was 3.33 and the mean number of total expanders inserted was 4.83. Complication associated with expander exposure occurred in 1 patient during the fifth expansion. The average score of aesthetic outcome in the multiple reexpansion group was superior to that of the conventional group (2.60 versus 2.10, P = 0.03). During the telephone survey, patients did not rate their appearance as positive, although they were comparatively satisfied with the surgical procedure. CONCLUSION Considering the low rate of malignancy involving congenital melanocytic nevus in childhood, multiple reexpansion is an attractive option to obtain better results compared with other reconstructive methods.

Abstract
BACKGROUND Spontaneous lightening of congenital melanocytic naevi (CMN) has not been studied systematically. Final colour is considered an important outcome after superficial removal techniques such as curettage, dermabrasion or laser ablation, and is often compared with colour at birth. OBJECTIVES To quantify the natural history of CMN lightening over time, and explore phenotypic and genotypic predictors of colour change. METHODS A longitudinal cohort study was undertaken of 110 patients with CMN (mean follow-up 5·3 years). Accurate colour-space measurements were taken from professional serial photographs of CMN and normal skin. Changes in colour over time were modelled using multiple logistic regression, against phenotypic and genotypic variables. RESULTS Lightening of CMN was significantly associated with lighter normal skin colour (P < 0·001) and with MC1R variant alleles (red/blonde hair gene) (P < 0·001), but not with CMN colour in the first 3 months of life, NRAS genotype or projected adult size of CMN. Importantly, the final colours of adjacent treated and untreated areas of CMN were indistinguishable. CONCLUSIONS Final CMN colour in childhood is related to the genetically determined skin colour of the individual, is unrelated to the colour of CMN at birth, and is unaffected by superficial removal. What's already known about this topic? Final colour of congenital melanocytic naevi (CMN) is considered an important outcome after superficial removal techniques such as curettage, dermabrasion or laser ablation, and is often compared with colour at birth. The phenomenon of spontaneous lightening in CMN, in which naevi lighten gradually and sometimes dramatically during childhood, has been described but not systematically studied. What does this study add? Final CMN colour in childhood is significantly associated with the individual's normal skin colour, and with MC1R genotype, and is therefore genetically determined. Final CMN colour is not predictable from CMN colour in the first 3 months of life. Superficial removal techniques do not alter the final colour of CMN.

Abstract
We report the case of a newborn boy with multinodular NRAS and BRAF mutation-negative congenital melanocytic nevi and cerebral lesions compatible with congenital intraparenchymal melanosis. Histopathology from skin lesions showed atypical nodular melanocytic proliferation with marked melanocytic atypia and a large number of mitoses and apoptosis, indicating aggressive proliferation. The child developed several new subcutaneous tumors and multiple internal lesions, which were confirmed to be metastases, and died at 5 months of age. This case may represent an infantile melanoma developing from a giant congenital melanocytic nevus or a congenital melanoma.

Abstract
We report a novel treatment for giant congenital melanocytic nevi (GCMN) that involves the reuse of resected nevus tissue after high hydrostatic pressurization (HHP). However, the remaining melanin pigments in the inactivated nevus tissue pose a problem; therefore, we performed a long-term observation of the color change of inactivated nevus tissue after HHP. Pressurized nevus specimens (200 MPa group, n = 9) and non-pressurized nevus tissues (control group, n = 9) were subcutaneously implanted into nude mice (BALB/c-nu) and then harvested 3, 6, and 12 months later. Color changes of the nevus specimens were evaluated. In the 200 MPa group, the specimen color gradually regressed and turned white, and brightness values were significantly higher in the 200 MPa group than in the control group after 6 months. This indicated that melanin pigments in the pressurized nevus tissue had spontaneously degraded and regressed. Therefore, it is not necessary to remove melanin pigments in HHP-treated nevus tissue.

Abstract
Integra dermal regeneration template has been well established in treating deep extensive burns, but there are very few cases reported of treating large full-thickness skin defects such as giant nevi. Apart from psychological and cosmetic burdens, the giant congenital nevus carries increased risk of malignant alteration. We present the case of a 9-year-old girl with a giant congenital nevus on her left lower leg. A total excision was done and she was successfully treated with Integra (LifeSciences Corp, Plainsboro, NJ). Three weeks later, a thin split-skin graft was applied over the neodermal skin layer. The takeoff was 91%. Protected with the silver wound dressing, the rest of the wound healed. A donor site morbidity was minimal, and the final result was excellent both in aesthetic and functional aspects.

Abstract
BACKGROUND: Large congenital melanocytic nevus (LCMN) is considered a risk factor for melanoma, although the magnitude of this risk is controversial. OBJECTIVE: To evaluate the risk of melanoma development in patients with LCMN seen at a dermatology referral center in Brazil during a twelve-year period. To the best of our knowledge, there are no published similar studies on large congenital melanocytic nevus in South America. METHODS: Our prospective cohort included only patients with congenital nevi ≥20cm. The cumulative risk of developing melanoma and the standardized morbidity ratio were calculated for patients followed up prospectively for at least 1 month. RESULTS: Sixty-three patients were enrolled in this study. One patient who developed melanoma prior to enrollment was excluded, and five were eliminated because of insufficient follow-up time. Mean follow-up for the remaining 57 patients was 5.5 years (median 5.2 years). Median age of entry into the study was 2.6 years. Most patients (75.4%) underwent only clinical observation. Melanomas occurred in 2 (3.5%) patients. Five-year cumulative risk for melanoma was 4.8% (95% CI: 1.9-11.5%). Standardized morbidity ratio was 1584 (95% CI: 266-5232, p<0.001). STUDY LIMITATIONS: The small sample size reduces the accuracy of risk estimates. CONCLUSIONS: This study analyzed prospectively for the first time data from South America demonstrating that patients with LCMN have a higher risk of developing melanoma than the general population (p<0.001).

Abstract
Garment-like giant congenital melanocytic nevi are very rare, and those being treated are most often offered excision and split-thickness skin transplantation. Due to the risk of restricted mobility secondary to shrinkage and hypertrophic scarring of the transplant, we treated to date the largest reported giant congenital melanocytic nevus (16% total body surface area) with Integra dermal regeneration template (Integra Life Sciences, Plainsboro, N.J.), giving a more functional skin reconstruction. In addition, the dermal regeneration template had to be covered with split-thickness skin transplant including multiple smaller nevi due to lack of larger area with normal skin.

Abstract
Background Treatment of giant melanocytic nevi (GMN) remains a multidisciplinary challenge. We present analysis of diagnostics, treatment, and follow-up in children with GMN to establish obligatory procedures in these patients. Material/Methods In 24 children with GMN, we analyzed: localization, main nevus diameter, satellite nevi, brain MRI, catecholamines concentrations in 24-h urine collection, surgery stages number, and histological examinations. The t test was used to compare catecholamines concentrations in patient subgroups. Results Nine children had “bathing trunk” nevus, 7 had main nevus on the back, 6 on head/neck, and 2 on neck/shoulder and neck/thorax. Brain MRI revealed neurocutaneous melanosis (NCM) in 7/24 children (29.2%), symptomatic in 1. Among urine catecholamines levels from 20 patients (33 samples), dopamine concentration was elevated in 28/33, noradrenaline in 15, adrenaline in 11, and vanillylmandelic acid in 4. In 6 NCM children, all catecholamines concentrations were higher than in patients without NCM (statistically insignificant). In all patients, histological examination of excised nevi revealed compound nevus, with neurofibromatic component in 15 and melanoma in 2. They remain without recurrence/metastases at 8- and 3-year-follow-up. There were 4/7 NCM patients with more than 1 follow-up MRI; in 1 a new melanin deposit was found and in 3 there was no progression. Conclusions Early excision with histological examination speeds the diagnosis of melanoma. Brain MRI is necessary to confirm/rule-out NCM. High urine dopamine concentration in GMN children, especially with NCM, is an unpublished finding that can indicate patients with more serious neurological disease. Treatment of GMN children should be tailored individually for each case with respect to all medical/psychological aspects.

Abstract
INTRODUCTION The incidence of congenital nevi is one over 20,000 newborns per year, 14 % of them are located in the head and neck area. Nevi of the orbital region are particularly difficult to handle on the aesthetic and functional side. The objectives of this study were to conduct an analysis of different clinical presentations of congenital nevi of the eyelid orbital region in children to establish a treatment algorithm. MATERIEL AND METHODS We realised a bi-centric retrospective study including 51 children with orbito-palpebral congenital nevi. We analysed the different clinical presentations, their treatments and their results. RESULTS Nineteen underwent direct suture excision; three a total skin graft; 15 a combination of treatments, among them four underwent tissular expansion and 14 patients were not operated and clinically followed-up. The average follow-up time was 6.6 years. In 33 cases residual nevic area was still present. The postoperative sequelae were: dyschromia (n=17), anatomical deformation of the eye (n=10), nevi outbreaks (n=8), internal canthus deformation (n=5) and ectropion (n=1). CONCLUSION The results of our study show that therapeutic abstention is preferred when the aesthetic wrong is accepted by the patient and when there is not a higher risk of malignant degeneration. In order to minimise the risk of postoperative sequelae, we propose a therapeutic algorithm for the management of congenital orbital nevi.

Abstract
A new or changing melanocytic nevus in a child or adolescent often leads to concern in parents and physicians. To avoid undue alarm and unnecessary procedures, dermatologists should be aware of the natural history and clinical spectrum of nevi in pediatric patients, as well as findings that are potentially worrisome in this age group. This review provides an update on melanocytic nevi in children, focusing on their dynamic evolution over time, molecular insights into nevogenesis, and phenotypic markers for increased risk of melanoma in adolescence and adulthood. Special considerations for Spitz nevi and nevi located in particular sites (eg, scalp, acral, genital) are highlighted. Current understanding of the risks associated with congenital melanocytic nevi of different sizes and strategies for the management of children with numerous acquired nevi, Spitz nevi, and congenital nevi are also discussed.

Abstract
Giant congenital melanocytic nevus is usually defined as a melanocytic lesion present
at birth that will reach a diameter ≥ 20 cm in adulthood. Its incidence is estimated
in <1:20,000 newborns. Despite its rarity, this lesion is important because it may
associate with severe complications such as malignant melanoma, affect the central
nervous system (neurocutaneous melanosis), and have major psychosocial impact on the
patient and his family due to its unsightly appearance. Giant congenital melanocytic
nevus generally presents as a brown lesion, with flat or mammilated surface,
well-demarcated borders and hypertrichosis. Congenital melanocytic nevus is primarily
a clinical diagnosis. However, congenital nevi are histologically distinguished from
acquired nevi mainly by their larger size, the spread of the nevus cells to the deep
layers of the skin and by their more varied architecture and morphology. Although
giant congenital melanocytic nevus is recognized as a risk factor for the development
of melanoma, the precise magnitude of this risk is still controversial. The estimated
lifetime risk of developing melanoma varies from 5 to 10%. On account of these
uncertainties and the size of the lesions, the management of giant congenital
melanocytic nevus needs individualization. Treatment may include surgical and
non-surgical procedures, psychological intervention and/or clinical follow-up, with
special attention to changes in color, texture or on the surface of the lesion. The
only absolute indication for surgery in giant congenital melanocytic nevus is the
development of a malignant neoplasm on the lesion.

Abstract
SUMMARY Congenital melanocytic nevi remain a subject of controversy with respect to risk of malignant transformation and recommended management. Recent studies indicate a lower malignant risk (0.7 to 2.9 percent) than had previously been estimated. Surgery has not been proven to reduce malignant risk or improve quality of life, and may result in undesirable aesthetic and functional outcomes. In this article, the authors review key controversial issues in the management of congenital melanocytic nevi and re-evaluate indications for surgical treatment. An updated review of controversial topics in the management of congenital melanocytic nevi is presented, and clinical applications are demonstrated through clinical cases. Updates regarding the risks and outcomes of congenital melanocytic nevi patients open a renewed debate with respect to the indications for surgery as well as the extent of surgery that may be suitable. Treatment should be tailored to achieve optimal aesthetic results whereby complete nevus excision is not the goal. As such, nonsurgical management and incomplete nevus excision should be integrated as legitimate parts of any treatment algorithm.

Abstract
Treatment of congenital melanocytic nevi (CMN) is generally undertaken for 2 reasons: (1) to reduce the chances of cutaneous malignant melanoma and (2) for cosmetic reasons. Over the past century, a large number of treatments for CMN have been described in the literature. These include excision, dermabrasion, curettage, chemical peels, radiation therapy, cryotherapy, electrosurgery, and lasers. Only low-level evidence supporting these approaches is available, and large randomized controlled trials have not been published. This article explores therapeutic controversies and makes recommendations based on the best available evidence.

Abstract
Congenital melanocytic nevi (CMN) are pigmented birthmarks that affect up to 80% of the skin surface area. The increased frequency of CMN in families of severely affected individuals is suggestive of a predisposing germline genotype. We noted a high prevalence of red hair in affected families, and considered a role for MC1R in this condition. A cohort of 166 CMN subjects underwent pigmentary phenotyping, with MC1R genotyping in 113. Results were compared with a local control group of 60 unrelated children and with 300 UK children without CMN. CMN subjects had higher prevalences of red hair and a red-haired parent than local controls and had a higher rate of compound heterozygosity and homozygosity for MC1R variants. The presence of a V92M or R allele (D84E, R151C, R160W, D294H) was associated with increasing size of the CMN, implying a growth-promoting effect of these alleles. Unexpectedly, the V92M and R151C alleles were also strongly associated with birth weight in the CMN cohort, a finding confirmed in the control group. The effect of germline MC1R genotype on development and severity of CMN led us to investigate potential broader effects on growth, revealing a role for MC1R in normal fetal development.

Abstract
Congenital melanocytic nevi are commonly encountered in clinical practice. Although the development of malignant melanoma arising in small and intermediate congenital melanocytic nevi is rare, there is a significant risk of malignant degeneration associated with large congenital melanocytic nevi, in particular those that arise on the torso in the so-called "bathing trunk" distribution, where the risk is estimated to be about 2.5% to 5%. The risk of malignant melanoma arising within a large congenital melanocytic nevus is highest in the first 5 to 10 years of life and carries a significant mortality. Large congenital melanocytic nevi, in particular those overlying the posterior axis and occurring in the context of multiple satellite melanocytic nevi, are also associated with the development of neurocutaneous melanosis, which may result in neurologic and neurodevelopmental sequelae and is associated with a significant risk of primary central nervous system melanoma and death.

Abstract
Mounting evidence from animal studies has implicated that all commonly used anaesthetics and sedatives may induce widespread neuronal cell death and result in long-term neurological abnormalities. These findings have led to serious questions regarding the safe use of these drugs in young children. In humans, recent findings from retrospective, epidemiological studies do not exclude the possibility of an association between surgery with anaesthesia early in life and subsequent learning abnormalities. These results have sparked discussions regarding the appropriate timing of paediatric surgery and the safe management of paediatric anaesthesia. However, important questions need to be addressed before findings from laboratory studies and retrospective clinical surveys can be used to guide clinical practice. This article summarises the currently available preclinical and clinical information regarding the impact of anaesthetics, sedatives, opioids, pain and stress, inflammation, hypoxia-ischaemia, co-morbidities and genetic predisposition on brain structure and long-term neurological function. Moreover, this article outlines the putative mechanisms of anaesthetic neurotoxicity, and the phenomenon's implications for clinical practice in this rapidly emerging field.
