Papulosis fibrosa blanca del cuello: a propósito de un caso / White fibrous papulosis of the neck: about a case

La papulosis fibrosa blanca del cuello es una patología benigna, que se presenta frecuentemente en personas mayores y que se caracteriza por pápulas blanquecinas ubicadas habitualmente en las regiones laterales del cuello. El hallazgo histopatológico distintivo es el incremento de las fibras de colágeno en la dermis papilar. Su etiopatogenia es, hasta ahora, desconocida y su tratamiento es difícil. Dado que corresponde a una patología infrecuente, probablemente subdiagnosticada, es que se decide reportar el caso de una mujer chilena de 77 años.

White fibrous papulosis of the neck is a benign pathology, which usually occurs in old people and is characterized by whitish papules that are frequently located in the lateral regions of the neck. The distinctive histopathological finding is the increase of collagen fibers in the papillary dermis. Its pathophysiology is not currently known and its treatment is difficult. Due to being a rare pathology, probably underdiagnosed, it was decided to report the case of a 77-yearold chilean woman.

Avaliação de 40 ritidoplastias realizadas no Hospital Federal do Andaraí segundo duas técnicas distintas: smasplastia cervicofacial mediante sutura de vetores e retalho subSMAS / Evaluation of 40 rhytidoplasties performed at the Federal Hospital of Andaraí to compare two different techniques: cervicofacial SMAS-plasty according to vector suturing and the sub-SMAS flap approach

Introdução: A ritidoplastia se tornou uma das cirurgias estéticas mais realizadas no mundo. Alguns preferem uma abordagem mais conservadora e outros defendem que, para obter resultados mais duradouros e efetivos, necessitam de intervenções agressivas. O objetivo é comparar resultados de 40 ritidoplastias realizadas no Hospital Federal do Andaraí ao longo de 22 meses, utilizando duas técnicas distintas, smasplastia mediante sutura de vetores e retalho subSMAS. Métodos: Trata-se de um estudo descritivo em que 20 pacientes foram submetidas à smasplastia e outras 20 à retalho subSMAS. Um avaliador observou sob o ponto de vista estético algumas variáveis em regiões específicas da face e classificou a melhora baseado em fotografias pré-operatórias e 6 meses após o procedimento. A observação da ficha de coleta de dados possibilitou quantificar as complicações nas duas técnicas separadamente. Resultados: As duas técnicas demonstraram resultados semelhantes sob o ponto de vista estético com o objetivo de rejuvenescimento facial, melhora da flacidez cervical e definição da transição face/pescoço. Em especial, o retalho proporcionou melhores resultados na atenuação no sulco nasogeniano. Houve um caso de hematoma em cada técnica. Houve uma lesão nervosa na smasplastia. Não houve lesão do nervo facial, nem infecção. Edema superior a 3 meses foi mais prevalente naquelas submetidas ao retalho. Conclusões: Os dois métodos possuem vantagens e desvantagens e o melhor resultado depende do grau de envelhecimento do esqueleto facial, da perda de apoio de tecidos frouxos em áreas críticas como a região malar e próxima ao sulco labiomandibular, da característica de pele no pré-operatório e da experiência do cirurgião na técnica empregada.

Introduction: Rhytidectomy has become one of the most performed aesthetic surgeries in the world. Some surgeons prefer a more conservative approach, and others maintain that aggressive interventions are required to obtain results that are more durable and effective. This study aimed to compare the results of 40 rhytidectomies performed using either of two techniques, namely superficial musculoaponeurotic system (SMAS)-plasty according to vector suturing and the sub-SMAS flap approach, at the Federal Hospital of Andaraí over 22 months. Methods: This is a descriptive study that included 20 patients who underwent SMAS-plasty and 20 patients who received a sub-SMAS flap. An assessor identified some variables in specific regions of the face from an aesthetic point of view, and he rated improvements based on photographs obtained before and 6 months after operation. The data collected allowed to quantify complications of both techniques separately. Results: From an aesthetic point of view, the two techniques showed similar results in terms of facial rejuvenation, improvement of cervical flaccidity, and definition of face/neck transition. The flap provided better results regarding the attenuation in the nasogenian sulcus. A case of hematoma occurred in each technique. Nerve injury occurred in the SMAS-plasty group. However, neither facial nerve injury nor infection occurred in both groups . Edema for >3 months was more prevalent in the sub-SMAS flap group. Conclusions: The two methods have advantages and disadvantages, and the best result depended on the degree of aging of the facial skeleton, the loss of supporting tissues in critical areas such as the malar region and next to the labiomandibular fold, the preoperative characteristic of the skin, and the surgeon's experience in the technique.

Remodeling of the middle third of the face with fillers / Remodelamento do terço médio da face com preenchedores

Facial aging is a consequence of multiple intrinsic and extrinsic interactive factors, leading to loss of volume and repositioning of facial fat and bone remodeling. Breakthroughs have been seen in recent decades in the ability to reduce the signs of aging. Filling techniques and numerous products available on the market have generated new interest in the study of facial anatomy. Fillers are able to restore volume in limited areas and are suitable for treating facial wrinkles and loss of subcutaneous volume. The gold standard remains hyaluronic acid because it is more biocompatible and has greater permanence in the skin, without being definitive. The objective of this report is to review the anatomy of the middle third of the face and the main indications for filling and the techniques used for rejuvenation.

O envelhecimento facial é consequência de múltiplos fatores intrínsecos e extrínsecos que interagem entre si, levando à perda de volume e reposicionamento da gordura facial, assim como o remodelamento ósseo. Nas últimas décadas, houve um grande avanço na Medicina em reduzir os sinais do envelhecimento. As técnicas de preenchimento e os inúmeros produtos disponíveis no mercado trouxeram novo interesse no estudo da anatomia da face. Os preenchedores têm como função restaurar o volume de áreas restritas, portanto, são adequados para tratar rugas faciais e perda de volume subcutâneo. O padrão ouro atualmente é o ácido hialurônico, por ser mais biocompatível e ter uma permanência maior na pele, sem ser definitivo. O objetivo desse artigo é revisar a anatomia do terço médio da face, assim como as principais indicações de preenchimento e técnicas utilizadas para o rejuvenescimento.

Immunohistochemical and light and electron microscopic study of the basement membrane in photoaged skin

The basement membrane plays an important role in maintaining a healthy epidermis and dermis, and repeated damage destabilizes the skin and accelerates the aging process. This study was carried out to detect the changes in human skin basement membrane in sun-exposed skin compared with sun-protected skin. Skin biopsies were taken from sun-exposed and sun-protected skin of 10 male individuals aged between 50 and 60 years and processed for light and electron microscopic examination of the changes of the basement membrane. Immunohistochemical assessment of laminin and matrix metalloproteinase-1 [MMP-1] expression in skin biopsies was also carried out. Histological examination of sections of sun-exposed skin revealed that the basement membrane was discontinuous and the collagenous fibers of the underlying connective tissue were discrete in comparison with sun-protected skin. Immunoreactivity for laminin was decreased, whereas that for MMP-1 was markedly increased in sun-exposed skin as compared with sun-protected skin. The results of the current study revealed that the structure of the basement membrane was affected in sun-exposed skin as regards thickness, continuity, and structure. Increased activity of MMP-1 accounts at least in part for the disruption of the basal lamina and degradation of collagenous fibers of the dermis

Luz intensa pulsada no fotoenvelhecimento: avaliação clínica, histopatológica e imuno-histoquímica / Intense pulsed light in photoaging: a clinical, histopathological and immunohistochemical evaluation

FUNDAMENTOS: A luz intensa pulsada tem sido muito utilizada no tratamento do fotoenvelhecimento sem completo conhecimento de seu mecanismo de ação. OBJETIVO: Estudar a ação da luz intensa pulsada no fotoenvelhecimento e na resposta imunológica cutânea por meio de estudo clínico, histopatológico, avaliando células de Langerhans (CD1), expressão da molécula de adesão intercelular, de linfócitos CD4 e CD8 e quantificação de colágeno e fibras elásticas. MÉTODOS: Um total de 26 pacientes, com idades entre 40 e 65 anos, com fototipos II a III de Fitzpatrick, foram tratadas do fotoenvelhecimento usando LIP, em 5 sessões, com intervalo mensal, durante o ano de 2006. Todas as pacientes foram submetidas à avaliação histológica e imuno-histoquímica 6 meses após o tratamento. RESULTADOS: Ao término do tratamento, houve melhora clínica em 76,92 por cento dos casos, estando relacionada ao aumento significante de fibras colágenas (51,33 por cento) e elásticas (44,13 por cento). O tratamento com luz intensa pulsada promoveu redução de linfócitos CD4 e não alterou a intensidade de linfócitos CD8. Além disso, promoveu aumento significante de pequenos vasos sanguíneos, não ectásicos, molécula de adesão intercelular positivos. CONCLUSÃO: O tratamento facial com luz intensa pulsada promoveu intensa melhora clínica que foi comprovada pelo estudo histopatológico da pele, constituindo boa opção de tratamento para o fotoenvelhecimento cutâneo, por ser técnica não- ablativa, segura e eficaz.

BACKGROUND: Intense pulsed light has been used in the treatment of photoaging without a full understanding of its mechanism of action. OBJECTIVE: To study the effect of intense pulsed light on photoaging and on the skin immune response by means of a clinical and histopathological study, evaluating Langerhans cells (CD1), expression of intercellular adhesion molecule, of CD4 and CD8 lymphocytes and quantification of collagen and elastic fibers. METHODS: In 2006 a total of 26 patients, aged 40 to 65 years, with phototypes II to III (Fitzpatrick scale), were treated for photoaging using intense pulsed light in five sessions with a monthly interval. All the patients were subjected to histological and immunohistochemical evaluation 6 months after treatment. RESULTS: At the end of the treatment clinical improvement was observed in 76.92 percent of cases. This improvement was associated to a significant increase of collagen (51.33 percent) and elastic (44.13 percent) fibers. Intense pulsed light treatment led to a reduction of CD4 lymphocytes and did not alter the amount of CD8 lymphocytes. It also led to a significant increase of small, nonectatic blood vessels, positive intercellular adhesion molecule. CONCLUSION: Facial treatment with intense pulsed light promoted major clinical improvement that was confirmed by histological examination of the skin. This technique is a good treatment option for skin photoaging because it is non-ablative, safe and effective.

Histopathological aspects of cutaneous photoaging and phenol peeling

The skin is regarded as the largest organ in our system and has the general purposes of physical, mechanical and immunological protection, sealing against the elements and thermoregulation and tactile perception of environmental stimuli. Skin aging is a complex biological event that affects all skin layers. The dermis, however, is particularly affected due to its histophysiologies' characteristics. With the expansion of life expectancy, the dermatological questions among the older population has had an increasingly bigger importance, propelling the development and perfecting of rejuvenation techniques. The phenol peeling is a deep, chemical one, which offers intense clinical results. The application on small areas of the body, for example, around the eyes, is safe and does not lead to cardiovascular complications. This review aims to update the knowledge of skin histology, the alterations related to photoaging and phenol peeling.

Standard guidelines of care: CO2 laser for removal of benign skin lesions and resurfacing.

Resurfacing is a treatment to remove acne and chicken pox scars, and changes in the skin due to ageing. MACHINES: Both ablative and nonablative lasers are available for use. CO 2 laser is the gold standard in ablative lasers. Detailed knowledge of the machines is essential. INDICATIONS FOR CO 2 LASER: Therapeutic indications: Actinic and seborrheic keratosis, warts, moles, skin tags, epidermal and dermal nevi, vitiligo blister and punch grafting, rhinophyma, sebaceous hyperplasia, xanthelasma, syringomas, actinic cheilitis angiofibroma, scar treatment, keloid, skin cancer, neurofibroma and diffuse actinic keratoses. CO 2 laser is not recommended for the removal of tattoos. AESTHETIC INDICATIONS: Resurfacing for acne, chicken pox and surgical scars, periorbital and perioral wrinkles, photo ageing changes, facial resurfacing. PHYSICIANS' QUALIFICATIONS: Any qualified dermatologist (DVD or MD) may practice CO 2 laser. The dermatologist should possess postgraduate qualification in dermatology and should have had specific hands-on training in lasers either during postgraduation or later at a facility which routinely performs laser procedures under a competent dermatologist/plastic surgeon, who has experience and training in using lasers. For the use of CO 2 lasers for benign growths, a full day workshop is adequate. As parameters may vary in different machines, specific training with the available machine at either the manufacturer's facility or at another centre using the machine is recommended. FACILITY: CO 2 lasers can be used in the dermatologist's minor procedure room for the above indications. However, when used for full-face resurfacing, the hospital operation theatre or day care facility with immediate access to emergency medical care is essential. Smoke evacuator is mandatory. PREOPERATIVE COUNSELING AND INFORMED CONSENT: Detailed counseling with respect to the treatment, desired effects, possible postoperative complications, should be discussed with the patient. The patient should be provided brochures to study and also given adequate opportunity to seek information. Detailed consent forms need to be completed by the patients. Consent forms should include information on the machine used; possible postoperative course expected and postoperative complications. Preoperative photography should be carried out in all cases of resurfacing. Choice of the machine and the parameters depends on the site, type of lesion, result needed, and the physician's experience. ANESTHESIA: Localized lesions can be treated under eutectic mixture of local anesthesia (EMLA) cream anesthesia or local infiltration anesthesia. Full-face resurfacing can be performed under general anesthesia. Proper postoperative care is important to avoid complications.

Aspectos indicativos de envelhecimento facial precoce em respiradores orais adultos / Indicative factors of early facial aging in mouth breathing adults

TEMA: envelhecimento facial precoce em respiradores orais adultos. OBJETIVO: verificar a presença de aspectos indicativos de envelhecimento facial precoce e caracterizar morfometricamente as medidas da projeção do sulco nasogeniano ao tragus e da largura facial (distância entre os bucinadores) em respiradores orais e nasais adultos. MÉTODO: foi realizada, em 60 indivíduos, observação de aspectos indicativos de envelhecimento facial precoce (presença de olheiras, rugas embaixo dos olhos, rugas mentuais e sulco mentual). Em seguida, foram tomadas medidas da projeção do sulco nasogeniano ao tragus e da largura facial (distância entre os bucinadores) utilizando-se paquímetro eletrônico digital. Posteriormente, os voluntários foram submetidos às avaliações fonoaudiológica (anamnese e avaliação miofuncional orofacial) e otorrinolaringológica (anamnese, avaliação clínica e exame de videonasofaringolaringoscopia) para diagnóstico da respiração oral. Após os dados obtidos serem caracterizados com a utilização de técnicas de estatística descritiva, aplicou-se os testes de aderência de Kolmogorov-Smirnov e Shapiro-Wilk e os testes de hipótese Qui-quadrado, Mann-Withney e o teste T de Student para variáveis independentes. As diferenças foram consideradas significativas para valores de p menores que 0,05 e o erro beta admitido foi de 0,1. RESULTADOS: a amostra foi composta apenas por voluntários do sexo feminino. Verificou-se, no grupo teste (respiradores orais), média de idade de 22,04 ± 2,25 anos e, no grupo controle (respiradores nasais), 21,94 ± 2,03 anos. Observou-se, no grupo de respiradores orais, um percentual mais elevado da presença de aspectos indicativos de envelhecimento facial precoce quando comparado aos respiradores nasais, bem como maiores diferenças entre as projeções dos sulcos nasogenianos nas hemifaces direita e esquerda. Entretanto, foram observados maiores valores de largura facial nos respiradores nasais, configurando faces...

BACKGROUND: early facial aging in mouth breathing adults. AIM: to verify the presence of indicative factors of early facial aging and to characterize the measurements of the projection of the nasogeniane fold to the tragus and of the face width in mouth and nose breathing adults. METHOD: aspects of early facial aging were observed in 60 individuals (presence of dark circles and wrinkles under the eyes, mentual wrinkles and mentual ridges). Measurements of the projection of the nasogeniane fold to the tragus and of the face width (distance between the buccinators) were taken using a digital caliper. Later, the volunteers were submitted to speech-language evaluations (anamneses and orofacial myofuntional assessment) and to an otolaryngology inspection in order to establish the diagnosis of mouth breathing (anamneses, clinical evaluation and video laryngoscopy). The obtained data were analyzed according to descriptive statistics and to the following statistic tests: Kolmogorov-Smirnov, Shapiro-Wilk, Qui-square, Mann-Withney and the T-Student test for independent variables. Differences were considered significant when the p value was inferior to .05 and the accepted beta error was of .1. RESULTS: the research sample consisted only of female volunteers. For the research group (mouth breathers) the age average was of 22.04 ± 2.25 years and, for the control group (nose breathers) the age average was of 21.94 ± 2.03 years. The presence of a high percentage of indicative factors of early facial aging was observed for the group of mouth breathers when compared to the group of nose breathers. Greater differences between the projections of the nasogenianos ridges in right and left side of the face was also observed for the group of mouth breathers. However, higher values of face widths were observed for the nose breathing individuals, configuring a discreetly more widened face in the cheek region. CONCLUSIONS: in the present study there was a higher...

Com a idealizaçäo da técnica, decidiu-se realizar um trabalho científico no qual os autores selecionaram 10 pacientes. Como resultados, apresentaram 4 pacientes considerados bons, 3 regulares e 3 insuficientes

Pseudoxantoma elástico símil elastólisis dérmica papilar / Pseudoxanthoma elasticum like papillary dermal elastolysis

Presentamos una paciente de 71 años, de sexo femenino, que presenta lesiones cutáneas de un año de evolución. Las mismas son pápulas interfoliculares blanquecinas en las regiones laterales y posterior del cuello, que semejan pseudoxantoma elástico. Los exámenes oftalmológico y cardiovascular fueron normales. La histología reveló ausencia de fibras elásticas en la dermis papilar. Con estos hallazgos se realizó el diagnóstico de pseudoxantoma elástico simil elastólisis dérmica papilar. Esta nueva entidad forma parte de lo que Rongioletti y colaboradores denominaron síndromes fibroelastolíticos relacionados con la edad, considerados como patrones clínico-patológicos del envejecimiento cutáneo intrínseco

Fibropapulosis blanca del cuello / White fibrous papulosis of the neck

Se presenta un caso de fibropapulosis blanca del cuello en una mujer de 63 años con numerosas lesiones papulosas no confluentes en el cuello y zonas del mentón. Debido a que la fibropapulosis blanca del cuello es de reciente reconocimiento, se discuten asimismo los diagnósticos diferenciales que esta afección plantea, tales como el pseudoxantoma elástico clásico y su variedad "pseudoxantoma elástico-simil con elastólisis dérmica papilar", así como el tricodiscoma, el acrocordón, las anetodermias, la dermatofibrosis lenticular diseminada, el nevo conectivo eruptivo y la "piel cetrina" de Milian
