ABSTRACT

Abstract This retrospective study evaluated facial profile pleasantness determined by two protocols of Class II treatment. The sample comprised facial profile silhouettes obtained retrospectively from the pretreatment (T1) and posttreatment (T2) cephalograms of 60 patients (42 males and 18 females) divided into two groups. One group of 30 patients (mean age of 12.84 years) was treated with the extraction of maxillary first premolars (mean treatment time of 2.7 years), and the other group of 30 patients (mean age of 12.81 years) was treated with a mandibular advancement appliance (Forsus) (mean treatment time of 2.49 years). The facial profile silhouettes (T1 and T2) were randomly distributed in an album containing one patient per sheet. The examiners consisted of 60 orthodontists and 60 lay individuals, who analyzed the profiles in regard to facial pleasantness, using the Likert scale. A comparison between stages T1 and T2 of the two treatment protocols and between the examiners was performed by mixed-design analysis of variance at a significance level of 5%. The results demonstrated a significant difference between T1 and T2 (greater scores for T2 compared to T1), and between lay individuals and orthodontists (orthodontists assigned higher scores), but with no significant difference between the treatment protocols. Both protocols produced positive effects on the facial profile esthetics, from the standpoint of lay individuals and orthodontists.

ABSTRACT

Introdução: O número de pacientes classificados com sobrepeso ou obesos e, com isso, dos pacientes pós-bariátricas vem aumentando, gerando uma demanda por ritidoplastias neste perfil de público. O objetivo é expor a rotina e táticas cirúrgicas em um hospital de ensino, o perfil destes pacientes, além de um comparativo superficial histológico da pele, tecido celular subcutâneo e SMAS, entre os pacientes pós e não pós-bariátrica. Métodos: Foi realizado revisão de dados do centro cirúrgico e de prontuário entre os anos de 2012 e 2016 em um hospital público na cidade de Goiânia-GO, com levantamento de 32 casos. Resultados: A tática de ritidoplastia utilizada nos pacientes pós-bariátrica não apresenta grandes diferenças entre a utilizada nos pacientes não pós-bariátrica. A análise histopatológica das amostras colhidas evidenciou diferenças marcantes entre os pacientes pós e não pós-bariátrica. Conclusão: Percebeu-se que a técnica operatória na ritidoplastia do paciente pós-bariátrica sustentou detalhes específicos, com resultado cirúrgico pós-operatório satisfatório, uma pele de pior qualidade histológica, com complicações perioperatórias dentro do esperado e com necessidade de maiores estudos para avaliar durabilidade do procedimento.


Introduction: The number of patients classified as overweight or obese has resulted in an increased number of post-bariatric patients, generating a demand for rhytidoplasty in this public profile. The objective is to expose the routine and surgical tactics in a teaching hospital, patient profiles, subcutaneous cellular tissue, and the superficial musculoaponeurotic system are compared between post-bariatric and non-post-bariatric patients, as well as histological superficial comparison of the skin. Methods: A review of the data of 32 cases treated in 2012­2016 was conducted in a public hospital in Goiânia-GO. Results: The tactics of rhytidoplasty used in post-bariatric patients do not differ significantly from those used in nonpost- bariatric patients. A histopathological analysis of the collected samples showed marked differences between post-bariatric and non-post-bariatric patients. Conclusion: The surgical technique of rhytidoplasty of post-bariatric patients sustained specific details with satisfactory postoperative surgical results, skin with worse histological quality, perioperative complications within the expected range, and the need for further studies to assess the procedure's durability

ABSTRACT

Abstract Soft tissue defects around dental implants, such as papilla or volume loss, peri-implant recession and alterations of the ridge color and/or texture, lead to esthetic and functional complaints. Treatments of these defects in implants are more demanding than in teeth because peri-implant tissue exhibits different anatomical and histological characteristics. This narrative review discusses the proposed treatments for soft tissue defects around implants in the current literature. Several clinical and pre-clinical studies addressed methods to augment the quantity of the peri-implant keratinized mucosa. Autogenous grafts performed better than soft tissue substitutes in the treatment of soft tissue defects, but there is no clinical consensus on the more appropriate donor area for connective tissue grafts. Treatment for facial volume loss, alterations on the mucosa color or texture and shallow peri-implant recessions are more predictable than deep recessions and sites that present loss of papilla. Correction of peri-implant soft tissue defects may be challenging, especially in areas that exhibit larger defects and interproximal loss. Therefore, the regeneration of soft and hard tissues during implant treatment is important to prevent the occurrence of these alterations.

ABSTRACT

ABSTRACT INTRODUCTION: Studies that assess the upper airways in sleep-related breathing disorders have been performed only in patients with obstructive sleep apnea syndrome who seek medical attention. Therefore, in addition to the need for population studies, there are no data on the orofacial-cervical physical examination in subjects with upper airway resistance syndrome. OBJECTIVES: To compare the orofacial-cervical examination between volunteers with upper airway resistance syndrome and without sleep-related breathing disorders. METHODS: Through questionnaires, physical measurements, polysomnography, and otorhinolaryngological evaluation, this study compared the orofacial-cervical physical examination, through a systematic analysis of the facial skeleton, mouth, throat, and nose, between volunteers with upper airway resistance syndrome and volunteers without sleep-related breathing disorders in a representative sample of the adult population of the city of São Paulo. RESULTS: There were 1042 volunteers evaluated; 49 subjects (5%) were excluded as they did not undergo otorhinolaryngological evaluation, 381 (36%) had apnea-hypopnea index > 5 events/hour, and 131 (13%) had oxyhemoglobin saturation < 90%. Among the remaining 481 subjects (46%), 30 (3%) met the criteria for the upper airway resistance syndrome definition and 53 (5%) met the control group criteria. At the clinical evaluation of nasal symptoms, the upper airway resistance syndrome group had more oropharyngeal dryness (17% vs. 29.6%; p = 0.025) and septal deviation grades 1-3 (49.1% vs. 57.7%; p = 0.025) when compared to controls. In the logistic regression model, it was found that individuals from the upper airway resistance syndrome group had 15.6-fold higher chance of having nose alterations, 11.2-fold higher chance of being hypertensive, and 7.6-fold higher chance of complaining of oropharyngeal dryness when compared to the control group. CONCLUSION: Systematic evaluation of the facial skeleton, mouth, throat, and nose, between volunteers with upper airway resistance syndrome and volunteers without sleep-related breathing disorders, showed that the presence of upper airway resistance syndrome is mainly associated with nasal alterations and oropharyngeal dryness, in addition to the risk of hypertension, regardless of gender and obesity.


Resumo Introdução: Estudos que avaliam a via aérea superior (VAS) nos distúrbios respiratórios relacionados ao sono (DRRS) foram realizadas somente em pacientes com Síndrome da apneia obstrutiva do sono (SAOS) que procuram o atendimento médico. Portanto, além da necessidade de estudos populacionais, não há dados sobre o exame físico cérvico-orofacial em indivíduos com Síndrome de Resistência das Vias Aéreas Superiores (SRVAS). Objetivos: Comparar o exame cérvico orofacial entre voluntário com SRVAS e sem DRRS. Método: Através de questionários, medidas físicas, polissonografia e avaliação otorrino-laringológica comparou-se o exame físico cérvico orofacial, através de uma análise sistemática do esqueleto facial, boca, faringe e nariz, entre voluntários com SRVAS e voluntários sem DRRS em uma amostra representativa da população adulta da cidade de São Paulo. Resultados: Avaliamos 1042 voluntários. Foram excluídos: 49 indivíduos (5%) que não realizaram avaliação otorrinolaringológica; 381 (36%) apresentaram índice de apneia e hipopnéia (IAH) > 5 eventos/hora e 131 (13%) apresentaram saturação da oxihemoglobina < 90%. Entre os 481 voluntários restantes (46%), 30 (3%) preenchiam os critérios estabelecidos para a definição de SRVAS e 53 (5%) que preenchiam os critérios do grupo controle. Na avaliação clínica dos sintomas nasais, o grupo SRVAS apresentou mais ressecamento orofaríngeo (17% vs. 29,6%; p = 0,025), desvio septal grau 1 a 3 (49,1% vs. 57,7%; p = 0,025), comparado ao controle. No modelo de regressão logística observamos que indivíduos do grupo SRVAS apresentaram uma razão de chance 15,6 vezes maior de apresentarem nariz alterado; 11,2 vezes maior de serem hipertensos e 7,6 vezes maior de se queixarem de ressecamento orofaríngeo quando comparados ao grupo controle. Conclusão: A avaliação sistemática do esqueleto facial, boca, faringe e nariz, entre voluntários com SRVAS e voluntários sem DRRS, mostrou que a presença de SRVAS está principalmente associada à alterações nasais e ressecamento orofaríngeo, além do risco de hipertensão arterial, independentemente do gênero e obesidade.

ABSTRACT

INTRODUÇÃO: Lipomas são os tumores benignos mesenquimais mais comuns. Entretanto, são pouco frequentes na face, principalmente o tipo considerado gigante, derivado do coxim adiposo bucal. A literatura é escassa e provavelmente a sua incidência é subestimada. MÉTODO: Relato do caso de tratamento cirúrgico de lipoma gigante bucal e temporal recidivado, e revisão da literatura no Pubmed na língua inglesa e na Revista Brasileira de Cirurgia Plástica. RESULTADOS: O tumor, anatômica e morfologicamente, corresponde ao coxim adiposo bucal, foi totalmente retirado pelo acesso facial e temporal, sem sequelas ao nervo facial. Foram encontrados 31 casos relatados de lipoma de origem do coxim adiposo bucal, entretanto, vários casos foram encontrados e relatados sob outras denominações. DISCUSSÃO: O coxim adiposo bucal é maior e mais complexo que se conhecia, e várias patologias se derivam deste, sendo importante o diagnóstico diferencial do lipoma simples com o de células fusiformes e com o lipossarcoma, devido a sua extrema semelhança. CONCLUSÃO:Nas lesões lipomatosas da face, a possível origem no coxim adiposo bucal deve ser considerada. Um estudo amplo dessas lesões com a finalidade de uniformizar a terminologia e de determinar a sua real incidência deve ser realizado.


INTRODUCTION: Lipomas are the most common benign mesenchymal tumors. Nevertheless, they are infrequent in the face, particularly giant lipomas, which are derived from the buccal fat pad. The literature regarding these tumors is scarce and their incidence is likely underestimated. METHODS: We present a case report of surgical treatment of a relapsed giant buccal and temporal lipoma and review the related English literature in Pubmed and that in the Brazilian Journal of Plastic Surgery. RESULTS: The tumor, which anatomically and morphologically corresponded to the buccal fat pad, was completely excised by facial and temporal access without sequelae to the facial nerve. A total of 31 reported cases of lipoma originating from the buccal fat pad were found; however, several were found and reported under other names. DISCUSSION: The buccal fat pad is larger and more complex than assumed, and several pathologies are derived thereof, making the differential diagnosis of simple lipoma with fusiform cell lipoma and liposarcoma difficult due to their extreme similarities. CONCLUSION: In lipomatous lesions of the face, the possible origin in the buccal fat pad must be considered. An extensive study of these lesions with the purpose of standardizing the terminology and determining its real incidence must be performed.

ABSTRACT

A síndrome de Barraquer-Simons é uma lipodistrofia caracterizada por progressiva atrofia do tecido celular subcutâneo limitada à parte superior do corpo. Seu acometimento costuma ser simétrico e com evolução craniocaudal, podendo atingir até as coxas. Também é conhecida como lipodistrofia céfalo-torácica ou lipodistrofia parcial progressiva. É uma doença rara, de origem obscura, que geralmente se manifesta no começo da segunda década de vida e tem predominância no sexo feminino. O presente trabalho objetiva trazer uma revisão da literatura e relatar um caso desta rara patologia e sua condução terapêutica, comparando-a a outras modalidades de tratamento disponíveis atualmente. Durante o período de um ano e três meses de seguimento, foram realizadas quatro sessões de enxertia de gordura seguindo os princípios da lipoenxertia estruturada. Por meio desta modalidade terapêutica, foi possível obter uma melhora importante do contorno facial com desaparecimento quase completo das depressões e irregularidades características da doença e preservação do resultado durante o tempo de acompanhamento. Diversos tipos de tratamentos foram descritos como efetivos para as lipodistrofias: uso de materiais aloplásticos, enxertos autólogos, retalhos locais e microcirúrgicos. Cada um deles possui suas vantagem e desvantagens e a escolha dependerá da experiência do cirurgião e da disponibilidade de recursos e materiais específicos em cada centro. A lipoenxertia se mostrou uma forma de tratamento eficaz, simples, segura e de baixo custo para tratamento da síndrome de Barraquer-Simons.


Barraquer-Simons syndrome is a type of lipodystrophy characterized by progressive atrophy of the subcutaneous tissue limited to the upper body. Its involvement is usually symmetrical with craniocaudal evolution, reaching down to the thighs. This syndrome is also known as cephalo-thoracic lipodystrophy or progressive partial lipodystrophy. It is a rare disease of unknown origin that usually manifests at the beginning of the second decade of life and has predominance among women. We report a case and literature review of this rare disease, its therapeutic management, and a comparison with other treatment modalities currently available. During one year and three months follow-up, four sessions of facial fat grafting were performed following the principles of structural fat grafting. The use of this therapeutic modality, improved significantly facial contour, and almost complete disappearance of depressions and irregularities, and preservation were achieved during follow-up time. A number of treatments have been described as effective for lipodystrophy, such as: use of alloplastic materials, autologous grafts, local and microsurgical flaps. Each treatment has advantages and disadvantages. Decision depends on the surgeon's experience, availability of resources, specific materials in each center.

ABSTRACT

INTRODUCTION: Mouth breathing (MB) is an etiological factor for sleep-disordered breathing (SDB) during childhood. The habit of breathing through the mouth may be perpetuated even after airway clearance. Both habit and obstruction may cause facial muscle imbalance and craniofacial changes.OBJECTIVE: The aim of this paper is to propose and test guidelines for clinical recognition of MB and some predisposing factors for SDB in children.METHODS: Semi-structured interviews were conducted with 110 orthodontists regarding their procedures for clinical evaluation of MB and their knowledge about SDB during childhood. Thereafter, based on their answers, guidelines were developed and tested in 687 children aged between 6 and 12 years old and attending elementary schools.RESULTS: There was no standardization for clinical recognition of MB among orthodontists. The most common procedures performed were inefficient to recognize differences between MB by habit or obstruction.CONCLUSIONS: The guidelines proposed herein facilitate clinical recognition of MB, help clinicians to differentiate between habit and obstruction, suggest the most appropriate treatment for each case, and avoid maintenance of mouth breathing patterns during adulthood.


INTRODUÇÃO: a respiração bucal (RB) é um fator etiológico para os distúrbios respiratórios do sono (DRS) na infância. O hábito de respirar pela boca pode ser perpetuado mesmo depois da desobstrução das vias aéreas. Tanto o hábito quanto a obstrução podem causar desequilíbrios da musculatura facial e alterações craniofaciais. O objetivo deste trabalho é propor e testar uma diretriz para o reconhecimento clínico da RB e de alguns fatores predisponentes aos DRS em crianças.MÉTODOS: entrevistas semiestruturadas foram realizadas com 110 ortodontistas, com relação aos seus procedimentos para avaliação clínica da RB e aos seus conhecimentos sobre DRS na infância. A partir daí, com base nas respostas obtidas, uma diretriz foi desenvolvida e testada em 687 crianças, com 6 a 12 anos, oriundas de escolas de ensino fundamental.RESULTADOS: não existe padronização para o reconhecimento clínico da RB pelos ortodontistas. Os procedimentos mais comumente realizados foram ineficientes para reconhecer a diferença entre a RB por hábito e a por obstrução.CONCLUSÕES: a diretriz proposta facilita o reconhecimento clínico da RB, diferencia entre RB por hábito e por obstrução, sugere o tratamento mais adequado para cada caso, e evita a manutenção do padrão de respiração bucal na idade adulta.

ABSTRACT

INTRODUÇÃO Esta revisão qualitativa da literatura analisou publicações científicas internacionais sobre possíveis alterações miofuncionais orofaciais em pacientes acometidos pela Síndrome de Parry-Romberg, por meio da base de dados PubMed. MÉTODOS: O levantamento realizado limitou-se a seres humanos, de qualquer faixa etária, no idioma inglês, entre os anos 2002 e 2012. As publicações sem acesso completo, repetidas por sobreposição das palavras-chave, revisões de literatura, cartas ao editor e as não relacionadas diretamente ao tema foram excluídas. RESULTADOS: Foram identificados 719 estudos, sendo 21 dentro dos critérios estabelecidos. Com base nos estudos selecionados, pacientes acometidos pela Síndrome de Parry-Romberg podem apresentar alterações dos tecidos mole e duro, tais como atrofia dos músculos esternocleidomastoideo, masseter e pterigoideos; atrofia na região da bochecha e depressão da prega nasolabial; desvio dos lábios e nariz; atrofia unilateral da língua; atrofia do ângulo da boca; reabsorção progressiva do osso da maxila e da mandíbula; atrofia do arco zigomático, do osso frontal e assimetria facial; desenvolvimento atrófico das raízes ou reabsorção patológica dos números de dentes permanentes; redução da mandíbula e erupção atrasada dos dentes superiores e inferiores. CONCLUSÃO: Apesar do crescente interesse pelo diagnóstico e pela descrição sintomatológica de indivíduos com Síndrome de Parry-Romberg, a escassez de publicações que abordem tratamentos funcionais e interdisciplinares é evidente. Verifica-se a necessidade da realização de estudos mais específicos que visem à melhoria da qualidade de vida desses pacientes.


INTRODUCTION This qualitative literature review analyzed international scientific publications on possible orofacial myofunctional alterations in patients with Parry-Romberg syndrome by using PubMed. METHODS: The survey was conducted in English, between 2002 and 2012, and was limited to human beings of any age. Publications without full access, duplicated by overlapping keywords, literature reviews, letters to the editor, and those not directly related to the research topic were excluded. RESULTS: We identified 719 studies, of which 21 were within the established criteria. Based on the selected studies, patients with Parry-Romberg syndrome may show changes in soft and hard tissues such as atrophy of the sternocleidomastoid, masseter, and pterygoid muscles; atrophy in the cheek region and depression of the nasolabial fold; deviation of the lips and nose; unilateral tongue atrophy; atrophy of the mouth angle; progressive resorption of the maxilla and mandible bone; atrophy of the zygomatic arch and frontal bone, and facial asymmetry; atrophic root development or pathological resorption of permanent tooth numbers; and jaw reduction and delayed eruption of the upper and lower teeth. CONCLUSION: Despite the growing interest in the diagnosis and symptomatic description of individuals with Parry-Romberg syndrome, publications that address functional and interdisciplinary treatments are scarce. Therefore, specific studies aimed at improving the quality of life of these patients are needed.

ABSTRACT

The aim of this study was to investigate the effects of reverse headgear (RH) on pharyngeal airway morphology in two groups of Class III patients with different vertical craniofacial features in comparison with an untreated Class III group. Seventeen subjects (9 males, 8 females; mean age 11.3 ± 0.98 years) with optimum vertical growth and 17 subjects (10 males, 7 females, mean age 11.5 ± 1.1 years) with a vertical growth pattern treated with a removable intra-oral appliance and a Delaire type facemask were included. An untreated Class III control group of 11 subjects (8 males, 3 females, mean age 9.1 ± 1.1 years) was included to compare the treated groups. The paired t-test for intragroup and one-way ANOVA for intergroup comparisons were performed. The relationships between changes in the craniofacial morphology and airway were assessed by Spearman correlation analysis. The airway dimensions at the adenoid side and soft palate were increased in the treatment groups compared to the control group (p < 0.05). The nasopharyngeal area demonstrated a significant difference in normodivergent and control subjects (p < 0.05). No significant difference was found in the airway morphology due to different vertical features. The effect of RH treatment on the sagittal airway dimensions revealed no significant difference between different vertical craniofacial features in the short term.

ABSTRACT

Temporomandibular disorders (TMD) affecting the articular disc and/or the facial muscles are common among the population, recording a higher incidence in women age 20-40 years. The aim of this study was to investigate the correlation between facial types and muscle TMD in women. This study comprised 56 women age 18 to 49 years, seeking treatment for TMD at the School of Medicine, Federal University of São Paulo. All of the study individuals were diagnosed with muscle TMD, based on the Research Diagnostic Criteria (RDC). Facial type was determined using the Facial Brugsch Index and classified as euryprosopic (short and/or broad), mesoprosopic (average width) and leptoprosopic (long and/or narrow). The data were submitted to the Chi-square test and ANOVA-Tukey’s test to conduct the statistical analysis. The faces of 27 individuals were classified as euryprosopic (48%), 18 as mesoprosopic (32%), and 11 as leptoprosopic (20%). A statistically significant difference (Chi-square, p = 0.032) was found among the facial types, in that leptoprosopic facial types showed the lowest values for muscle TMD. A greater number (p = 0.0007) of cases of muscle TMD were observed in the 20 to 39 year-old subjects than in the subjects of other age segments. In conclusion, women with euryprosopic facial types could be more susceptible to muscle TMD. Further studies are needed to investigate this hypothesis.

ABSTRACT

OBJECTIVE: The aim of this study is to assess dentoskeletal symmetry in cone-beam computed tomography (CBCT) scans of Brazilian individuals with Angle Class I malocclusion. MATERIAL: A total of 47 patients (22 females and 25 males) aged between 11 and 16 years old (14 years) seen in a private radiology service (CIRO, Goiânia, GO, Brazil) were assessed. All CBCT scans were obtained from January, 2009 to December, 2010. Cephalometric measurements were taken by multiplanar reconstruction (axial, coronal and sagittal) using Vista Dent3DPro 2.0 (Dentsply GAC, New York, USA). Minimum, maximum, mean and standard deviation values were arranged in tables, and Student t-test was used to determine statistical significance (P < 0.05). RESULTS: Data were homogeneous, and differences between the right and left sides were not significant. CONCLUSIONS: Cephalometric measurements of Brazilian individuals with Angle Class I malocclusion can be used to establish facial symmetry and three-dimensional standard references which might be useful for orthodontic and surgical planning. .


OBJETIVO: o objetivo deste estudo é avaliar a simetria dentoesqueléticas em imagens de tomografia computadorizada de feixe cônico (TCFC) de indivíduos brasileiros com má oclusão Classe I de Angle. MÉTODOS: quarenta e sete pacientes (22 meninas e 25 meninos), com idades entre 11 e 16 anos (14 anos, em média), foram atendidos em um serviço de radiologia privado. Todas as imagens de TCFC foram adquiridas a partir de janeiro de 2009 a dezembro de 2010. Medições cefalométricas foram realizadas por reconstruções multiplanares (axial, coronal e sagital) usando o VistaDent 3D Pro 2.0 ( Dentsply GAC, Nova Iorque, EUA). O desvio-padrão mínimo, máximo e a média foram descritos em tabelas, e o teste t de Student foi utilizado para definir significância estatística (p < 0,05). RESULTADOS: os dados foram homogêneos e as diferenças entre os lados direito e esquerdo não foram significativas.

ABSTRACT

Cone Beam Computed Tomography [CBCT] has the ability to accomplish rapid volumetric image acquisition by its cone-shaped beam. The aim of this study was to evaluate the safety and efficacy of this imaging modality A standard systematic review was performed. Medline [December 2012] and The Cochrane Library [Issue 3 2012] were searched to identify evidence about the performance [sensitivity, specificity and safety] of CBCT compared with other standard diagnostic methods. The results of the included studies were analyzed using a qualitative method Thirty-one articles were included in the study; the majority of them were diagnostic studies with a small sample size [n<10]. There was limited evidence about the effectiveness of this technology and the available evidence was scattered and sometimes controversial. At present, CBCT technology has greatly advanced and its image quality in terms of resolution is higher than that of MOCT. However, its contrast resolution is still lower than that of MOCT. Therefore, MOCT is preferred for soft tissue imaging. For evaluation of hard tissue in the maxillofacial region, a more clear image with higher resolution can be obtained by CBCT. CBCT technology is now commonly used in developed countries for obtaining detailed information regarding the oral and maxillofacial region and can greatly help clinicians in diagnosis and treatment of maxillofacial disorders

ABSTRACT

A large number of diseases may cause Atrophic skin disorders are caused by a large number of diseases, some of them idiopathic and others inflammatory, in which there is loss of volume of body segments. Localized scleroderma is a rare inflammatory dermatosis, manifested by atrophic skin and subcutaneous tissue alterations. Lipoatrophy may be genetically inherited or acquired as a result of panniculitis, HIV infections or aging. Many treatments have been proposed. Results vary in the acute inflammatory phase and are scarce when sclerosis and atrophy have already been established. This article describes four cases of localized facial scleroderma and one of facial idiopathic lipoatrophy treated with implantation of autologous fat globules extracted from the infragluteal groove, without utilization of cannula aspiration, with lasting results.


Os distúrbios atróficos da pele abrangem inúmeras doenças, algumas idiopáticas e outras, inflamatórias, em que há perda do volume de segmentos do corpo. A esclerodermia localizada é uma dermatose inflamatória, rara, que pode manifestar-se com alterações atróficas da pele e tecido subcutâneo. A lipoatrofia pode ser herdada geneticamente ou adquirida relacionada a paniculites, infeccção pelo HIV, ou envelhecimento. Muitos tratamentos são propostos. Os resultados são variáveis na fase inflamatória aguda e apresentam pouca resposta quando a esclerose e atrofia já estão instaladas. Descreve-se o tratamento de quatro casos de esclerodermia localizada e um de lipoatrofia idiopática, na face, tratados com enxerto de fragmentos de lóbulos de gordura autóloga extraídos sem a utilização da cânula aspirativa, com resultados duradouros.

ABSTRACT

La Histiocitosis de células de Langerhans (HCL) corresponde a una proliferación anormal de células dendríticas, de tipo clonal, cuyo espectro clínico general incluye compromiso de la piel y las mucosas, las uñas, el hueso, la médula ósea, el hígado, el bazo, linfonodos, el pulmón, el tracto gastrointestinal inferior, el sistema endocrino y el sistema nervioso central. En este trabajo presentamos tres casos de la enfermedad, con manifestaciones orales y craneofaciales, analizadas desde el punto de vista clínico (examen extra e intra oral), imagenológico (tomografías computadas) e histopatológico (expresión de marcador específico CD1a). Dos casos fueron clasificados como HCL de presentación aguda diseminada y uno como presentación crónica. Los pacientes fueron tratados oportunamente con quimioterapia según el protocolo del Programa Infantil Nacional de Drogas Antineoplásicas.


The Langerhans cell histiocytosis (LCH) corresponds to an abnormal proliferation of dendritic cells, clonal type, which usually involves compromise of skin and mucous membranes, nails, bone, bone marrow, liver, spleen, lymph nodes, lung, lower gastrointestinal tract, endocrine system and the central nervous system. We present three cases of the disease, with oral and craniofacial manifestations, analyzed from the clinical perspective (intra and extra oral exam), imaging (CT scans) and histopathological (specific marker CD1a expression). Two cases were classified as acute disseminated LCH presentation and one as a chronic disease. Patients were treated with chemotherapy timely according to the protocol of the National Child Program of Antineoplastic Drugs.

ABSTRACT

Tinea incognito (TI) is a dermatophytic infection which has lost its typical clinical appearance because of improper use of steroids or calcineurin inhibitors. The incidence of TI is increasing nowadays. We conducted retrospective review on 283 patients with TI from 25 dermatology training hospitals in Korea from 2002-2010 to investigate the demographical, clinical, and mycological characteristics of TI, and to determine the associated risk factors. More than half (59.3%) patients were previously treated by non-dermatologists or self-treated. The mean duration of TI was 15.0 +/- 25.3 months. The most common clinical manifestations were eczema-like lesion, psoriasis-like, and lupus erythematosus-like lesion. The trunk and face were frequently involved, and 91 patients (32.2%) also had coexisting fungal infections. Among 67 isolated strains, Trichophyton rubrum was the most frequently detected (73.1%). This is the largest study of TI reported to date and the first investigational report concerning TI in Korea. We suggest that doctors should consider TI when a patient has intractable eczema-like lesions accompanied by tinea pedis/unguium. Furthermore, there should be a policy change, which would make over-the-counter high-potency topical steroids less accessible in some countries, including Korea.
