Abstract Monilethrix is a rare defect of the hair shaft, with most cases showing an autosomal dominant pattern of inheritance and variable clinical expression. It is characterized by hypotrichosis secondary to hair fragility. The diagnosis is made through trichoscopy, detecting typical findings such as periodic narrowing at regular intervals, giving the hair the appearance of beads in a rosary. This article reports the case of six members of a family diagnosed with monilethrix with alopecia of varying degrees.

Abstract Five cases of telogen effluvium undergoing resolution are shown, with the presence of frontal, bitemporal, and occipital hair regrowth. Diagnosing acute telogen effluvium after the end of the active phase can be challenging, especially when the pull test is negative. The differential diagnosis includes alopecia areata and traction alopecia. Clinical signs of hair regrowth after telogen effluvium can help in the diagnosis. The frontal and temporal areas have more telogen hairs and are more affected. On the occipital area, hairs seem to have the same behavior. The acute telogen effluvium triad during resolution is proposed: frontal fringe, temporal recess and occipital fringe.

Resumo Transição capilar é o processo de abdicação de alisamentos químicos ou físicos dos cabelos, reassumindo suas texturas naturais. A presente pesquisa, de natureza qualitativa, visou a investigar a construção dos sentidos de identidade em mulheres negras que passaram pela transição capilar. Participaram do estudo 12 mulheres negras com idades compreendidas entre 18 e 34 anos. Para a coleta de dados foram utilizadas entrevistas semiestruturadas que foram analisadas através da análise de posicionamento. A transição capilar mudou a forma de posicionamento em relação a si, ao cabelo, à sociedade e à construção da autoimagem. Além de elucidar o processo de reafirmação identitária das interlocutoras, o estudo fomenta a discussão do racismo na sociedade brasileira, ao tratar da desvalorização da estética negra e, por conseguinte, do enaltecimento da branquitude.

Abstract Hair transition is the process of abdicating chemical or physical hair straightening, resuming its natural textures. This qualitative research aimed at investigating the construction of the meanings of identity in black women who went through the hair transition. Twelve black women between the ages of 18 and 34 participated in the study. For the data collection, semi-structured interviews were used and analyzed through the positioning analysis. Hair transition has changed the way of positioning towards itself, hair, society and the construction of self-image. In addition to elucidating the identity affirmation process of the interviewees, the study instigates the discussion of racism in Brazilian society, by dealing with the devaluation of black aesthetics and, therefore, the praise of whiteness.

Resumen La transición capilar es el proceso de abdicar del alisado químico o físico del cabello, retomando sus texturas naturales. La presente investigación, de carácter cualitativo, tuvo como objetivo investigar la construcción de los significados de la identidad en mujeres negras que atravesaron la transición capilar. Participaron del estudio doce mujeres negras de entre 18 y 34 años. Para la recolección de datos se utilizaron entrevistas semiestructuradas, las cuales fueron analizadas mediante análisis de posicionamiento. La transición capilar cambió la forma de posicionamiento en relación con una misma, el cabello, la sociedad y la construcción de la autoimagen. Además de dilucidar el proceso de afirmación identitaria de las interlocutoras, el estudio fomenta la discusión del racismo en la sociedad brasileña, al abordar la devaluación de la estética negra y, por tanto, el elogio de la blancura.

During aging, usually graying of the hair occurs as a result of oxidative stress. Driven by social acceptance and self-perception of the exterior appearance, both men and women rely on hair dyeing products, in order to mask the graying hair. At the same time, a frequent use of synthetic products and treatment can damage the hair shaft; for this reason, this study aimed to evaluate the morphological effect of the herbal dye derived from Lawsonia inermis (henna), on hair. Dyed hairs were evaluated by means of SEM. Subsequently, they were compared, qualitatively and quantitatively, with undyed hairs. Results showed a positive impact on the cuticula pattern and on the diameters of the examined samples, after henna application. Different results, about the degree and the type of morphological changes occurring on pigmented hairs, may depend on the phenotype and on the health condition of hair, before dye treatment.

Durante el envejecimiento, generalmente se produce el envejecimiento del cabello como resultado del estrés oxidativo. Motivados por la aceptación social y la autopercepción de la apariencia, tanto hombres como mujeres confían en productos para teñir el cabello para enmascarar las canas. Al mismo tiempo, el uso frecuente de productos y tratamientos sintéticos puede dañar el tallo del cabello. Por esta razón, este estudio tuvo como objetivo evaluar el efecto morfológico del tinte derivado de Lawsonia inermis (henna) en el cabello. Los cabellos teñidos se evaluaron mediante SEM. Posteriormente, se compararon, cualitativa y cuantitativamente, con cabellos sin teñir. Los resultados mostraron un impacto positivo en el patrón de la cutícula y en los diámetros de las muestras examinadas, después de la aplicación de henna. Los diferentes resultados, sobre el grado y el tipo de cambios morfológicos que ocurren en los cabellos pigmentados, pueden depender del fenotipo y del estado de salud del cabello, antes del tratamiento con tinte.

Formaldehyde is an active compound, irregularly used in hair products, that has the property of straighten and waterproofing the wires. However, it is highly toxic and can stimulate dermatological hypersensitivity and cancer. In this context it is of fundamental importance the inspection of these products that can be used in safe conditions for the consumer, without formaldehyde in concentrations higher than the allowed. Thus, the aim of this research was the qualitative and quantitative identification formaldehyde in samples of hair straighteners that was obtained by donation in the beauty salons of Araraquara-SP. In addition, the analysis of the packaging labels of the products tested were conducted, following the requirements of the national legislation - RDC 07/2015 which defines the mandatory labeling standards for cosmetic products. A qualitative analysis for formaldehyde identification is based on the formation of a purple colored complex. The quantitative analysis was performed by spectrophotometry. The qualitative and quantitative formaldehyde analysis methods were applied to 13 bottles of hair straighteners. When submitted to qualitative analysis, all samples showed formaldehyde presence. The quantitative analysis demonstrated that the samples identified as B, C, D, E, G, H, I, J and M presented formaldehyde concentration of 3.5 to 14.5%, which is above of the limit recommended by the National Health Surveillance Agency (ANVISA), of 0.2%. In the label analysis, in all samples were found irregularities.(AU)

BACKGROUND: Telogen effluvium (TE) is characterized by massive hair shedding and results from an abrupt conversion of anagen to telogen. Differentiation of TE with other hair disorders showing massive hair shedding is difficult.OBJECTIVE: To evaluate the morphologic characteristics of pulled out hair of TE.METHODS: We analyzed microscopic examination of pulled out hairs by hair pull test in TE patients, and compared these hairs with pulled out hairs in diffuse alopecia areata (AA) patients and healthy volunteers.RESULTS: Hair microscopic examination in 44 TE patients (370 hairs) and 30 healthy volunteers (295 hairs) were as follows: typical club hair, 32.7%, 62.7%; club hair with tail, 23.5%, 23.7%; club hair with remnant sheath, 23.0%, 6.8%; club hair with both tail and remnant sheath, 18.9%, 5.4%; and unclassified hair, 1.9%, 1.4%. The examination in 7 diffuse AA patients (63 hairs) was as follows: typical club hair, 23.9%; atypical club hair, 47.7%; and distinctive AA hair, 28.4%. There was statistical difference between TE patients and healthy volunteers group (p=0.000).CONCLUSION: Increased atypical club hair in microscopic hair examination might be characteristics of TE.

BACKGROUND@#Many studies have investigated heavy metal exposure could increase the occurrence of congenital heart defects (CHDs). However, there are limited data regarding the relationship between cobalt exposure and CHD occurrence in offspring. The aim of this study was to analyze the association between cobalt exposure in mothers and the risk of CHDs in offspring.@*MATERIALS AND METHODS@#In order to explore the association between cobalt exposure and occurrence of congenital heart defect (CHD), a case-control study with 490 controls and 399 cases with CHDs in China were developed. The concentrations of cobalt in hair of pregnant woman and fetal placental tissue were measured and processed by a logistic regression analysis to explore the relationship between cobalt exposure and risk of CHDs.@*RESULTS@#The median concentration of hair cobalt in the control and case group was 0.023 ng/mg and 0.033 ng/mg (aOR, 1.837; 95% CI, 1.468-2.299; P < 0.001), respectively. And the median (5-95% range) fetal placental cobalt concentrations were 19.350 ng/g and 42.500 ng/g (aOR, 2.924; 95% CI, 2.211-3.868; P < 0.001) in the control and case groups, respectively. Significant differences in the middle level of cobalt in hair were found in the different CHD subtypes, including septal defects, conotruncal defects, right ventricular outflow tract obstruction, and left ventricular outflow tract obstruction (P < 0.001). Dramatically, different cobalt concentrations in fetal placental tissue were found in all subtypes of cases with CHDs (P < 0.01).@*CONCLUSIONS@#The finding suggested that the occurrence of CHDs may be associated with cobalt exposure.

INTRODUCCIÓN: Las desigualdades socioeconómicas y territoriales se relacionan con la salud de la población santiaguina; sin embargo, los mecanismos causales que generan las inequidades en salud no están del todo claros. En este trabajo, se cuantifica el estrés de individuos viviendo en diferentes comunas, y se lo discute como causa y consecuencia de procesos vinculados con inequidades en salud. EL OBJETIVO era relacionar el Índice de Calidad de Vida Urbana (ICVU) de la comuna de residencia de individuos en Santiago de Chile con las concentraciones de cortisol en pelo (CCP), un biomarcador de los niveles de estrés fisiológico crónico. MATERIALES Y MÉTODOS: Se exploró la relación entre CCP y la edad, el sexo y el ICVU de la comuna de residencia en 80 estudiantes de educación superior en Santiago de Chile. RESULTADOS: No se encontraron correlaciones significativas entre CCP y la edad o el sexo de los participantes. Se encontró una correlación significativa entre CCP y los valores del ICVU de la comuna de residencia, además de encontrar diferencias significativas entre CCP y los distintos rangos de ICVU (Superior, Promedio e Inferior).DISCUSIÓN: Los resultados sugieren considerar las diferencias individuales de CCP como resultado de desigualdades socio-territoriales y también como posible causa de inequidades en salud. Se recomienda incluir el rol del estrés en las políticas públicas de salud, ampliando las redes de apoyo y prevención de estrés en los sectores con bajo ICVU.

INTRODUCTION: Socioeconomic and urban inequalities are associated with health in Santiago; nonetheless, the causal mechanisms underlying health inequalities are not entirely clear. This article quantifies the stress of individuals living in different municipalities and discusses its role as cause and consequence in the generation of health inequalities. THE OBJECTIVE of this study was to determine the relationship between the Urban Quality of Life Index (UQoLI) of individuals' municipality of residence in Santiago, Chile with their hair cortisol concentrations (HCC), a biomarker of chronic physiological stress.MATERIALS AND METHODS: The relationship of HCC with age, sex and UQoLI was explored in a sample of 80 university students in Santiago, Chile. RESULTS: No significant correlations were found between HCC and age and sex. A significant correlation was found between HCC and UQoLI, and significant differences were found be-tween HCC at different levels of UQoLI (High, Average, and Low).DISCUSSION: Results suggest that HCC differences could be considered a result of urban in-equalities, as well as a possible cause of health inequalities. The role of stress should be inclu-ded in public health policies, to expand support networks and prevent stress, especially among people living in areas with low urban quality of life.

Abstract Genital hair is one of the secondary sexual traits that marks the beginning of puberty; its removal has been part of human culture since ancient times. This practice may lead to modifications in vaginal microbiome with potential repercussions on skin health and balance. We conducted a narrative review with the purpose of describing normal skin microbiota, its impact under microenvironment changes and genital hair removal. Menses, pathological conditions and pubic hair removal may alter vaginal microbiota, being the latter of special relevance giving the risk of hair microtrauma, irritations and potential spread of infectious agents.

Resumo O cabelo genital é um dos traços sexuais secundários que marcam o início da puberdade; sua remoção faz parte da cultura humana desde os tempos antigos. Essa prática pode levar a modificações no microbioma vaginal com possíveis repercussões na saúde e equilíbrio da pele. Realizamos uma revisão narrativa com o objetivo de descrever a microbiota normal da pele, seu impacto nas alterações do microambiente e na remoção de pelos genitais. A menstruação, as condições patológicas e a remoção de pelos pubianos podem alterar a microbiota vaginal, sendo esta última de especial relevância dando o risco de microtraumatismo capilar, irritações e potencial disseminação de agentes infecciosos.

O processo de alisamento capilar é uma prática comum realizada nos salões de beleza. O procedimento exige a utilização de substâncias com capacidade de rompimento das cadeias dissulfídricas da fibra capilar com posterior modelamento para o efeito desejado, sendo o formol um dos compostos mais utilizados para esta finalidade, porém indevidamente. De acordo com a legislação vigente, o formol só pode ser utilizado em produtos cosméticos com a função de conservante em uma concentração máxima de 0,2%. Devido a seu uso incorreto em produtos capilares o presente trabalho teve como objetivo realizar uma análise semi-quantitativa da presença de formol em amostras de alisantes capilares, bem como verificar o pH destes produtos. Foram obtidas 22 amostras de alisantes capilares doadas por salões de beleza da região de Umuarama - PR. A determinação da presença de formol foi realizada através da reação de Shiff e comparação com escala colorimétrica de concentrações padronizadas de formaldeído variando de 0,005% a 10%. A verificação do pH foi realizada através da preparação de soluções aquosas de 10% do alisante e posterior aferição em pHmetro digital. Das amostras analisadas, verificou-se 22,72% encontraram-se em conformidade, apresentando quantidade de formaldeído adequada com a legislação (até 0,2%) ou ausência do composto, enquanto que 77,28% apresentaram valores acima do permitido. Já o pH adequado foi constatado em apenas 13,64% amostras. O uso incorreto ou exagerado do formol pode acarretar danos à saúde, como cefaléia, dispnéia, queimadura, edema pulmonar e até câncer. Uma maior fiscalização deve ser realizada nos estabelecimentos que realizam procedimentos de alisamento capilar, bem como nas indústrias produtoras e ainda em importadoras, para uma melhor garantia do cumprimento da legislação tanto para a preservação da saúde dos profissionais quando dos usuários.

The hair-straightening process is a common practice in most beauty salons. The procedure requires the use of substances capable of disrupting the disulfide chains of the hair fiber with subsequent modeling for the desired effect, with formaldehyde being one of the most commonly but improperly used compounds for this purpose. According to the current legislation, formaldehyde can only be used in cosmetic products as a preservative function in a maximum concentration of 0.2%. Due to its incorrect use in capillary products, this work has the purpose of developing a semi-quantitative analysis of the presence of formaldehyde in samples of hair straighteners, as well as verifying the pH of those products. Twenty-two samples of hair straighteners were donated by beauty salons from the region of Umuarama-PR. The determination of the presence of formaldehyde was performed using the Shiff reaction and compared using the colorimetric scale for standard formaldehyde concentrations varying from 0.005% to 10%. The pH verification was carried out by the preparation of 10% aqueous solutions of the straightener and subsequent measurement in a digital pH meter. From the analyzed samples, 22.72% were found to be in compliance, presenting the amount of formaldehyde within the legislation (up to 0.2%) or absence of the compound, while 77.28% presenting values above the legal limitations. Additionally, adequate pH was verified in only 13.64% of the samples. Incorrect or exaggerated use of formaldehyde can lead to health issues, such as headache, dyspnea, burns, pulmonary edema and even cancer. Greater surveillance should be carried out in establishments that perform hair straightening procedures as well as in the producing and importing industries in order to guarantee better compliance with the legislation both for the preservation of the health of professionals and users alike.

Abstract Dissecting cellulitis is an inflammatory, chronic, and recurrent disease of the hair follicles that mainly affects young Afro-descendent men. Trichoscopy is a method of great diagnostic value for disorders of the scalp. Clinical and trichoscopic findings of dissecting cellulitis are heterogeneous and may present features common to non-cicatricial and scarring alopecia. This article presents the trichoscopic findings of dissecting cellulitis that help in the diagnosis and consequent institution of the appropriate therapy and better prognosis of the disease.

Abstract Tinea incognito resulting from corticosteroid abuse is becoming very common in the tropics. Its diagnosis is tricky owing to its confusing morphology, as well as practical and technical issues associated with mycological tests. Dermoscopy has now evolved as a novel diagnostic tool for diagnosing tinea incognito in such challenging situations, since the typical hair changes such as Morse-code hairs, deformable hairs, translucent hairs, comma and cork screw hairs, and perifollicular scaling may be seen despite steroid use, irrespective of mycological results.

Neste trabalho, analisamos as narrativas de mulheres negras sobre seus cabelos, nos cuidados e apresentação dos mesmos, que trazem suas experiências e reflexões sobre como essas (trans)formaram suas identidades. As falas analisadas foram recolhidas de blogs e portais de notícias, disponíveis na Internet, em textos dedicados a discutir relações raciais, racismo, estética negra e feminismos negros. Para a análise, tomamos como referencial teórico os trabalhos de autoras/es que discutem questões raciais e processos de produção da identidade. Na análise do material foi possível pensar, a partir dos olhares dessas mulheres, seus processos de subjetivação desde a infância, na relação com as gerações mais velhas e o cuidado estético cotidiano. Em suas narrativas, dialogadas com referências teóricas que discutem processos de produção de identidade, bem como relações étnico-raciais, emergem experiências atravessadas por episódios explícitos e sutis de racismo. Os resultados apontam para a necessidade de uma maior interlocução da Psicologia com referenciais feministas e anti-racistas na teorização de processos de subjetivação de mulheres negras.(AU)

In this work, we analyze the narratives of black women on their hair, selfcare practices and appearence, which bring their experiences and reflections on how these (trans)formed their identities. The speeches analyzed were collected from blogs and news portals, available on the Internet, in texts dedicated to discuss racial relations, racism, black aesthetics and black feminisms. For the analysis, we take as theoretical referent the work of authors that discuss racial issues and processes of identity production. In the analysis of the material it was possible to think, from the perspective of these women, their processes of subjectivation since childhood, the relation with the older generations, and the daily aesthetic selfcare. In their narratives, dialogued with theoretical references that discuss processes of production of identity, as well as ethnic-racial relations, emerge experiences crossed by explicit and subtle episodes of racism. The results point to the need for a greater interlocution of Psychology with feminists and anti-racists references to theorize the processes of subjectivation of black women.(AU)

Abstract Introduction Brazil is the world's biggest consumer of crack cocaine, and dependence is a major public health issue. This is the first study to investigate the prevalence of potentially harmful adulterants present in hair samples from Brazilian patients with crack cocaine dependence. Method We evaluated adulterants in hair samples extracted by convenience from 100 patients admitted at the 48 hour-observation unit of Centro de Referência de Álcool, Tabaco e Outras Drogas (CRATOD), Brazil's largest center for addiction treatment. A cross-sectional analysis was performed with the data obtained. Results Adulterants were found in 97% of the analyzed hair samples. The most prevalent adulterant was lidocaine (92%), followed by phenacetin (69%) and levamisole (31%). Conclusion Adulterants were widely prevalent in hair samples from crack users treated at CRATOD: at least one adulterant was present in virtually all the hair samples collected. This points to a need to monitor adverse effects in the clinical setting in order to provide this high-risk group of patients with prompt and effective care related to the acute and chronic complications associated with these adulterants.

Resumo Introdução O Brasil é o maior consumidor mundial de crack, e a dependência é um grande problema de saúde pública. Este é o primeiro estudo a investigar a prevalência de adulterantes potencialmente nocivos presentes em amostras de cabelo de pacientes brasileiros com dependência de crack. Métodos Foram avaliados adulterantes em amostras de cabelos extraídos por conveniência de 100 pacientes internados na unidade de observação de 48 horas do Centro de Referência de Álcool, Tabaco e Outras Drogas (CRATOD), o maior centro de tratamento de dependência do Brasil. Uma análise transversal foi realizada com os dados obtidos. Resultados Foram encontrados adulterantes em 97% das amostras de cabelo analisadas. O adulterante mais prevalente foi a lidocaína (92%), seguida da fenacetina (69%) e levamisol (31%). Conclusão Os adulterantes foram amplamente prevalentes em amostras de cabelo de usuários de crack tratados no CRATOD: pelo menos um adulterante estava presente em praticamente todas as amostras de cabelo coletadas. Isso aponta para a necessidade de monitorar os efeitos adversos no ambiente clínico, a fim de proporcionar a esse grupo de pacientes de alto risco cuidados imediatos e efetivos relacionados às complicações agudas e crônicas associadas a esses adulterantes.

ABSTRACT Purpose: We aimed to compare the body mass index and vitamin and mineral status of children with and without amblyopia. Methods: Amblyopic children aged between 5 and 18 years (n=46) and age-matched control children (n=32) were evaluated in terms of anthropometric parameters, including height, weight, body mass index and demographic features. Serum vitamin B12 and folate were measured using an Advia Centaur XP (Siemens, Ireland) biochemistry analyzer. We evaluated the inorganic mineral elements from hair samples with inductively coupled plasma-mass spectrometry using a Thermo XSeries 2 analyzer (Thermo Fisher Scientific, Bremen, Germany). Results: No significant difference was found between the two groups in terms of height, weight, and body mass index or serum B12 and folate concentrations (p>0.05). Children with severe amblyopia had lower vitamin B12 and folate and higher body mass index. The levels of phosphorus (p=0.012), selenium (p=0.002), molybdenum (p<0.001), iodine (p=0.002), chromium (p=0.022), boron (p<0.001), and beryllium (p=0.005) were all significantly lower in the amblyopia group compared to the control group. All of these minerals, except phosphorus, were also significantly lower in those with severe amblyopia compared to those with milder amblyopia and controls (p<0.05). Conclusion: Amblyopic children are significantly deficient in some inorganic elements. Inorganic elements, vitamin B12, and folate may play an important role in the visual development of amblyopic children.

RESUMO Objetivo: Nosso objetivo foi comparar o índice de massa corporal e o nível de vitaminas e minerais de crianças com e sem ambliopia. Métodos: Crianças amblióticas com idades entre 5 e 18 anos (n=46) e crianças controle pareadas por idade (n=32) foram avaliadas quanto a parâmetros antropométricos, incluindo altura, peso, índice de massa corporal e características demográficas. A vitamina B12 e o folato séricos foram medidos utilizando um analisador bioquímico Advia Centaur XP (Siemens, Irlanda). Avaliamos os elementos minerais inorgânicos de amostras de cabelo com espectrometria de massa de plasma indutivamente acoplado usando um analisador Thermo XSeries 2 (Thermo Fisher Scientific, Bremen, Alemanha). Resultados: Não houve diferença significativa entre os dois grupos em relação à altura, peso e índice de massa corporal ou concentrações séricas de B12 e folato (p>0,05). Crianças com ambliopia severa tinham menor vitamina B12 e folato e maior índice de massa corporal. Os níveis de fósforo (p=0,012), selênio (p=0,002), molibdênio (p<0,001), iodo (p=0,002), cromo (p=0,022), boro (p<0,001) e berílio (p=0,005) foram todos significativamente menores no grupo com ambliopia em comparação com o grupo controle. Todos esses minerais, exceto o fósforo, também foram significativamente menores naqueles com ambliopia em comparação com aqueles com ambliopia leve e grupo controle (p<0,05). Conclusão: As crianças amblíopes são significativamente deficientes em alguns elementos inorgânicos. Elementos inorgânicos, vitamina B12 e folato podem desempenhar um papel importante no desenvolvimento visual de crianças com ambliopia.

Anhidrotic ectodermal dysplasia (AED) is a rare hereditary disorder with a triad of sparse hair, dental hypoplasia, and anhidrosis. Here we report a case of AED with food allergy and atopic eczema. The patient was a 11-month-old boy admitted to our hospital with pyrexia for 2 weeks. He presented with a history of dry skin, eczema, and food allergy to egg. On clinical examination, his body temperature was 38.8°C, with dry skin and eczema almost all over the body, sparse eyebrows, and scalp hair. Laboratory investigations and physical examination did not show any evidence of infection. Radioallergosorbent test was positive to egg yolk, egg white, ovomucoid, milk, house dust, and house dust mite. As the child did not sweat despite the high fever, we performed the sweat test which revealed a total lack of sweat glands. Genetic examination revealed a mutation of the EDA gene and he was diagnosed as AED. His pyrexia improved upon cooling with ice and fan. His mother had lost 8 teeth and her sweat test demonstrated low sweating, suggestive of her being a carrier of AED. Atopy and immune deficiencies have been shown to have a higher prevalence in patients with AED. Disruption of the skin barrier in patients with AED make them more prone to allergic diseases such as atopic eczema, bronchial asthma, allergic rhinitis and food allergy. Careful assessment of the familial history is essential to differentiate AED when examining patients with pyrexia of unknown origin and comorbid allergic diseases.

A trichobezoar is a type of bezoar that is composed of hair. In most cases, it is confined to the stomach, but in rare cases, it may extend to the small intestine. This condition is referred to as Rapunzel syndrome. The therapeutic method for bezoar removal depends on its type, location, and size. Generally, the treatment for Rapunzel syndrome involves surgical laparotomy. Endoscopic removal has also been effective in some cases. On the other hand, complications, such as respiratory difficulty and esophageal impaction may be encountered during endoscopic removal. Until now, the successful endoscopic removal of trichobezoars has been limited to the stomach or duodenum. This paper reports the case of a 4-year-old female patient with Rapunzel syndrome whose trichobezoar reached the proximal jejunum. The trichobezoar was removed without complications using an electrosurgical knife and snare through a single-balloon enteroscopy. The trichobezoar can be removed successfully using enteroscopy under general anesthesia without abdominal laparotomy in young children. Therefore, this method of removal can be considered preferentially for children with Rapunzel syndrome.
