15. Low-intensity laser therapy and led (light emitting diode) therapy in mechanical resistance of Rattus norvegicus chest inscision with implant of steel wire for sternal suture
INTRODUCTION: Low-intensity laser (LILT) and LED therapy are indicated in repairing surgical incisions, which occur in cardiac surgery. One major concern in this case is the presence of metallic wire used for sternal sutures, its temperature may rise while using a laser or LED. This study aimed to analyze the tensiometric properties of the skin tissue with l

16. Comparative study of skin pre and post fractional photothermolysis with Erbium-YAG 2940nm for the treatment of perioral wrinkles: a clinical, histological and immunohistochemical analysis / Estudo comparativo da pele pré e pós-laser fracionado minimamente ablativo com Erbium-YAG de 2940nm para tratamento de rítides da região perioral: avaliação clínica, anátomo-patológica e imuno-histoquímica
There are several treatment options for skin photoaging. One of them widely used nowadays is lasertherapy. The development of lasers technology introduced a new therapeutic concept for aging skin: ablative fractional photothermolysis. This technology combines the visible effects of an ablative therapy with the comfort and safety of nonablative methods. Befor

18. Estudo comparativo pré e pós luz intensa pulsada no tratamento do fotoenvelhecimento cutâneo: avaliação clínica, histopatológica e imunoistoquímica / Comparative study of pre and post pulsed intense light in the treatment of skin photoaging: clinical evaluation, histopathologic and immunohistochemistry
Introdução: A luz intensa pulsada(LIP) tem sido muito utilizada no tratamento do fotoenvelhecimento sem completo conhecimento de seu mecanismo de ação. Métodos: Foram acompanhados 26 pacientes apresentando fotoenvelhecimento grau II-III (GLOGAU, 1994), os quais foram submetidas à avaliação clínica , histológica e imunoistoquímica 6 e 12 meses apó

20. Validação do "bilicheck" para dosagem de bilirrubina em neonatos / Validation of "bilicheck" for bilirubin measurement in newborns
Aim: To compare transcutaneous bilirubin m easurement determined by ?Bilicheck®? with capillary serum measurement determined by ?U nistat-Leica Bilirubinometer? in newborns. Methods: A total of 200 newborns were included. For each one, paired measurements (serum, with ?Unistat-Leica Bilirubinometer? and transcutaneous, with ?Bilicheck®? were performed. The

21. Avaliação dos achados clínicos e histopatológicos nas lesões de poiquilodermia de Civatte antes e após o tratamento com luz intensa pulsada / An evaluation of the clinical and histopathological findings of the lesions of poikiloderma of Civatte before and after treatment with intense pulsed light
A poiquilodermia de Civatte é uma condição caracterizada por hiperpigmentação, telangiectasia e atrofia que acomete predominantemente o pescoço e a face de forma simétrica, poupando a área encoberta pelo mento. A sua ocorrência é associada à predisposição genética, à exposição cumulativa ao sol, ao processo de envelhecimento, à hipersensibi

22. Hipercromia cutânea idiopática da região orbital: avaliação clínica, histopatológica e imunohistoquímica antes e após tratamento com luz pulsada de alta energia / Cutaneous idiopathic hyperchromia of the orbital region: clinical, histopathological and immunohistochemestric evaluation before and after the treatment with intense pulsed light
Introdução: A hipercromia cutânea idiopática (HCIRO) não tem sua etiopatogenia bem esclarecida. Parecem estar envolvidos fatores genéticos (herança familiar autossômica dominante), aumento de melanina na derme, vasculatura proeminente e frouxidão da pele palpebral. Encontraram-se, na revisão da literatura, alguns artigos que contribuíram para o es

24. Photoisomerized bilirubin in blood from infants receiving phototherapy.
A pigment different from (Z,Z)bilirubin-IX alpha was detected by fluorometric methods in blood specimens from newborn infants undergoing blue-light therapy for unconjugated hyperbilirubinemia; it was not detected in specimens from infants not under therapy. The phototherapy-associated pigment has fluorescence, solubility, and photochemical properties that ar
