ABSTRACT

Abstract: Mohs micrographic surgery is a technique used to excise skin tumors based on comprehensive surgical mapping, in which the surgeon removes the tumor, followed by a complete histological evaluation of the tumor's margins. The correlation of the presence of a tumor in histological examinations and its precise location on the surgical map result in a complete removal of the tumor with maximum normal tissue preservation. The present article seeks to provide general practitioners and healthcare specialists with guidelines regarding recommendations for Mohs micrographic surgery to treat skin tumors, based on the most reliable evidence available in medical literature on the subject. This bibliographic review of scientific articles in this line of research was conducted based on data collected from MEDLINE/PubMed. The search strategy used in this study was based on structured questions in the Patient, Intervention, Control, and Outcome (PICO) format. MeSH terms were used as descriptors. The indications of this technique are related to recurrence, histology, size, definition of tumor margins, and location of tumors. These guidelines attempt to establish the indications of Mohs surgery for different types of skin tumors.

ABSTRACT

No Brasil, alguns serviços associam a curetagem da matriz ungueal à fenolização, como tentativa de aumentar a eficácia do tratamento da unha encravada. O objetivo deste trabalho foi comparar a taxa de cura entre a fenolização e a fenolização associada à curetagem da matriz. Foi realizado um estudo retrospectivo e incluídos 271 cantos encravados. Recorreram 5 por cento após a realização da fenolização, e 7,7 por cento após a fenolização com curetagem da matriz. Não houve diferença estatística entre as duas técnicas, mostrando não ser necessária a associação com a curetagem da matriz. A fenolização mostrou-se eficiente mesmo para o grau III.


Some services in Brazil combine curettage of the nail matrix with phenolization in the treatment of ingrown nails, with the objective of further increasing efficacy. The objective of this research was to compare the cure rates between the phenolization technique and phenolization associated with nail matrix curettage. A retrospective study was done which included 271 cases. There was only a 5 percent recurrence rate for the phenolization procedure, compared with 7.7 percent for combined phenolization/nail matrix curettage. There was no statistically significant difference between the two techniques, which indicated that there is no need for curettage of the nail matrix. Phenolization worked even for level III disease.

ABSTRACT

Introdução: A paroníquia crônica é uma doença infl amatória da prega ungueal proximal (PUP) com duração maior que seis semanas. Esta condição representa 18% das distrofi as ungueais. Caracteriza-se clinicamente por infl amação da PUP, ausência de cutícula e distrofi a da placa ungueal. O tratamento clínico é frequentemente insatisfatório. Já o tratamento cirúrgico consiste na retirada da PUP, que pode ser realizada pelas técnicas de incisão oblíqua ou perpendicular. Objetivo: Comparar a efi cácia entre as técnicas cirúrgicas oblíqua e perpendicular para o tratamento da paroníquia crônica. Material e métodos: Sessenta e dois pacientes com paroníquia crônica em um ou mais quirodáctilos (em um total de 138 casos operados) foram divididos de forma randomizada em dois grupos, conforme a técnica utilizada. A avaliação pós-operatória foi realizada após seis meses e foi utilizada uma escala de três pontos: sem melhora, melhorado e curado. Resultados: Cento e trinta e quatro casos (97,1%) foram considerados curados e quatro (2,9%), dois de cada grupo, foram considerados melhorados. Conclusão: Concluímos em nosso estudo que o tratamento cirúrgico é efetivo na paroníquia crônica, a despeito da técnica empregada.


Background and Objectives: Chronic paronychia is an infl ammatory disorder of the proximal nail fold (PNF) lasting more than six weeks, and accounts for 18% of nail dystrophies. Clinically, it is characterized by infl ammation of the PNF, absence of the cuticle, and dystrophy of the nail plate. Clinical treatment is, frequently, unsatisfactory. Surgical treatment consists on the removal of the PNF, which can be done using the oblique or perpendicular incision technique. The objective of the present study was to compare the effi cacy of oblique and perpendicular surgical techniques in the treatment of chronic paronychia. Methods: Sixty-two patients with chronic paronychia, in one or more fi ngers (for a total of 138 surgeries), were randomly divided in two groups according to the surgical technique used. Postoperative evaluation was done after six months using a three-point scale: absence of improvement, improved, cured. One hundred and thirty-four cases (97.1%) were considered cured, and 4 (2.9%), two in each group, were considered as having improved. Conclusion: In the present study, we concluded that the surgical treatment of chronic paronychia is effective, regardless of the technique used.

ABSTRACT

O pinçamento do leito ungueal gerado pela hipercurvatura transversa da unha é chamado de unha em pinça e pode provocar dor e constituir problema estético. A unha em pinça pode apresentar três tipos clínicos, mais comuns, sendo a unha em telha um deles. As causas podem ser hereditárias ou adquiridas. Os dedos dos pés são acometidos com maior freqüência. Os tratamentos conservadores são os preferidos pelos pacientes, porém, os tratamentos cirúrgicos produzem os melhores resultados. Das técnicas cirúrgicas, a técnica de Zook é opção diferente, pois, preserva a matriz e o tamanho da unha. Os autores apresentam cinco pacientes com unha em telha, tratados com a técnica de Zook.


The pinching of the distal nail bed, caused by transverse overcurvature of the nail is called pincer nail. It frequently causes pain and aesthetic problems. Pincer nail may present in three frequent clinical types, one being the tile-shaped nail. The causes may be hereditary or acquired. The toes are most frequently affected. Conservative treatments are preferred by patients, although surgical treatments produce better, longer-lasting results. Among the surgical techniques, Zook’s technique differs from others, because it preserves the matrix and consequently the size of nail. The authors evaluated five patients who presented pincer nails and were treated using Zook’s technique.
