Effects of long-pulsed 1064-nm Nd:YAG laser on telangiectasias and reticular veins: a human in-vivo histological study.

BACKGROUND: Telangiectasias and reticular veins are associated with aesthetic disorders. Sclerotherapy is the gold standard treatment, but long-pulsed 1064-nm Nd:YAG laser (LP1064 laser) is also used. No data on the human histological effects of these lasers are reported. The objective was to test different LP1064 laser parameters and their histological effects on the dermis, collagen, telangiectasias, and reticular veins. METHODS: This was a single-center, prospective, single-arm, case-control, human study. During surgery (dermolipectomy), the abdominal section of 10 female patients was irradiated with 6 different transdermal LP1064 laser parameters after anesthesia. Ten pieces with areas of varying irradiation were evaluated according to the characteristics of the vessels identified by area. In each piece, two irradiation areas were performed per group, totaling 12 irradiation areas per piece, with 120 regions later analyzed at the end of the ten samples. After removing the surgical product, histological sections were extracted, and the dermis, telangiectasias, and reticular veins were analyzed. RESULTS: Histological analysis showed that exposition to six different parameters from LP1064 laser led to significant dermal layer separation and collagen alterations. The effects were inconsistent on the loss of endothelial cells, intravascular thrombus formation, and fusion of vascular walls for both telangiectasias and reticular veins. In reticular veins, effects on intravascular thrombus formation and vascular wall fusion were not observed. CONCLUSIONS: The LP1064 laser in monotherapy with fixed settings did not lead to a consistent vascular lesion to promote immediate occlusion in telangiectasias and reticular veins. This strategy may not work as monotherapy for small vein treatment, but the possible late response to the LP1064 laser cannot be ruled out and require further investigation.

The impact of dermatoscopy on the pretreatment assessment of lower limbs telangiectasias: a prospective study.

BACKGROUND: Telangiectasias treatment can lead to skin hyperpigmentation, and pretreatment evaluation with dermoscopy was never performed. This study aimed to evaluate the applicability of dermatoscopy before telangiectasias treatment. METHODS: A prospective study evaluating patients of both sexes (18 to 60 years old), with telangiectasias (venous disease C2-C3 CEAP) of the lower limbs treated at outpatient clinics. Subjects who had never undergone previous interventional treatment for CVI and Fitzpatrick Classification up to phototype III, were included. Patients were submitted to both naked and dermoscopy evaluations of their skin and blindly evaluated by three vascular surgeons and an experienced dermatologist. Agreement by naked eye versus dermoscopy and among examiners was performed using Kappa correlation. Agreement by naked eye among patients and the examiners consensus were performed. RESULTS: There was a more significant agreement between the most experienced examiners in the naked eye assessment. With the dermatoscopic device, the highest agreement was maintained among the more experienced examiners, with a predominance of choice of the purple pigment in 29 of the 38 limbs, which represents a simple agreement of 76.3% (95% CI: 62.8-89.8%) with a Kappa concordance Index of 0.178. There was an agreement between the patient and the consensus of the naked eye examiners in 41.2% (95% CI: 24.7-57.7%). CONCLUSIONS: The dermatoscopy was not decisive for diagnosing skin pigmentation in areas of telangiectasia that had never been treated. The diagnostic accuracy was directly related to the clinical experience of the examiner. Dermatoscopy did not help in aligning expectations with treatment between physicians and patients.

Effectiveness of Secondary Alveolar Bone Graft on Canine Eruption: Systematic Review.

There are controversies related to the effects of bone grafts on tooth eruption and impaction in patients with cleft lip and palate. The aim of this systematic review was to evaluate the effectiveness of bone grafting on eruption of canines in patients with unilateral cleft lip and palate (UCLP). An electronic search was conducted in six electronic databases and gray literature, without limitations on year of publication or language. The primary outcome was the increase in rate of canine eruption; the secondary outcomes were success of the bone graft, canine impaction due to agenesis of the lateral incisor, and effect of orthodontic treatment before and after bone grafting. The risk of bias was analyzed by means of the tool Cochrane risk of bias in nonrandomized controlled trials (NRCTs) of interventions (ROBINS-I). The certainty of the evidence was assessed for outcomes reported through a narrative synthesis using grading of recommendations, assessment, development and evaluation (GRADE) approach. Four NRCTs were included, with a total of 360 patients, 283 UCLP and 77 bilateral cleft lip and palate (BCLP). The studies reported association between the increase in the rate of tooth eruption and bone graft with very low certainty of evidence, and greater experience of surgical success, with low certainty of evidence. The majority of the studies found an association between increase in the rate of canine impaction and agenesis of the lateral incisor, with very low certainty of evidence. There was very low certainty of the efficacy of secondary alveolar bone grafting for increasing the rates of eruption and reducing impaction of the maxillary canine.

Use of oxybutynin for treating plantar hyperhidrosis.

BACKGROUND: To evaluate the effectiveness and patient satisfaction with the use of oxybutynin at low doses for treating plantar hyperhidrosis. METHODS: From January 2007 to December 2010, 35 consecutive patients with plantar hyperhidrosis were treated with oxybutynin. Data were collected from 30 patients (five patients were lost to follow-up). During the first week, patients received 2.5 mg of oxybutynin once a day, 2.5 mg twice a day from the eighth to the 42nd day, and from the 43rd day to the end of the 12th week, 5 mg twice a day. All of the patients underwent two evaluations: before and after the oxybutynin treatment, using a clinical questionnaire, and a clinical protocol for quality of life. RESULTS: More than 70% of patients experienced an improvement in plantar hyperhidrosis. Most of the patients showed improvements in quality of life (66.6%). The side effects were minor, the most frequent being dry mouth (76.7%). CONCLUSION: Treatment of plantar hyperhidrosis with oxybutynin presents good results and improves quality of life. We believe that this therapeutic alternative is an excellent choice for the initial treatment of plantar hyperhidrosis.

Long-term comparison of video-assisted thoracic sympathectomy and clinical observation for the treatment of palmar hyperhidrosis in children younger than 14.

The results of video-assisted thoracic sympathectomy (VATS)in children are unknown. To investigate the improvement in quality of life (QOL) of a group of 45 children who did and did not undergo VATS for the treatment of palmar hyperhidrosis (PH) 4 years after the initial evaluation. Forty-five children with PH were initially evaluated. Children were divided into two groups: 30 in the VATS group and 15 in the control group. We studied the evolution of PH, negative effect of hyperhidrosis on the QOL before the treatment, and improvement in QOL after treatment. Twenty-five patients (83.4%) in the VATS group experienced great improvement in PH, and five (16.6%) experienced partial improvement; 12 (80.0%) children from the control group had some type of improvement, and three (20.0%) had partial improvement. Two (13.3%) children in the control group and 23 (76.7%) in the VATS group had great improvement in QOL. For children with PH and poor QOL, VATS is better than no treatment. It produces better results with regard to sweating and greater improvement in QOL.

The use of oxybutynin for treating axillary hyperhidrosis.

BACKGROUND: To evaluate the effectiveness and patient satisfaction with the use of oxybutynin for treating axillary hyperhidrosis in a large series of patients. METHODS: One hundred two patients with axillary hyperhidrosis were treated with oxybutynin. During the first week, patients received 2.5 mg of oxybutynin once a day in the evening. From the 8th to the 42nd day, they received 2.5 mg twice a day, and from the 43rd day to the end of the 12th week, they received 5 mg twice a day. All of the patients underwent two evaluations: before and after (12 weeks) the oxybutynin treatment, using a clinical questionnaire; and a clinical protocol for quality of life (QOL). RESULTS: More than 80% of the patients experienced an improvement in axillary hyperhidrosis; 36.3% of them presented a great improvement, and half of the patients showed improvements at all hyperhidrosis sites. Most of the patients showed improvements in the QOL (67.5%). The patients with very poor QOL before the treatment presented greater satisfaction levels after treatment. The side effects were minor, dry mouth being the most frequent (73.5%). CONCLUSIONS: Oxybutynin is a good alternative to sympathectomy. It presents good results and improves QOL without the side effects of sympathectomy.

The use of oxybutynin for treating facial hyperhidrosis.

BACKGROUND: Facial hyperhidrosis is a disease that may lead patients to serious emotional disturbances. Video-assisted thoracic sympathectomy provides excellent resolution of facial hyperhidrosis, but is associated with certain complications. The most frequent and important complication is compensatory hyperhidrosis. Especially in patients who have undergone resection of the second thoracic ganglion, the risk of severe compensatory hyperhidrosis is higher, which may cause dissatisfaction with the procedure. OBJECTIVE: The aim of this study was to evaluate the efficacy of the use of low doses of oxybutynin in treating facial hyperhidrosis as well as the level of patient satisfaction with its use. METHODS: 25 patients with facial hyperhidrosis were treated with oxybutynin. The patients underwent 2 evaluations: before and after treatment. These evaluations were used to assess the patients' clinical improvement and quality of life. RESULTS: We observed that more than 75% of the patients evolved with an improvement in facial hyperhidrosis, and 52% of them presented a great improvement. CONCLUSION: Treatment of facial hyperhidrosis with oxybutynin is a good alternative to sympathectomy, since it presents good results and improves quality of life, in addition to not exposing patients to the risk of experiencing the side effects of sympathectomy.

An alternative to treat palmar hyperhidrosis: use of oxybutynin.

PURPOSE: To evaluate the effectiveness and patient satisfaction with the use of oxybutynin at low doses for treating palmar hyperhidrosis in a large series of patients. METHODS: From January 2007 to June 2009, 180 consecutive patients with palmar hyperhidrosis were treated with oxybutynin. Data were collected from 139 patients (41 patients were lost to follow-up). During the first week, patients received 2.5 mg of oxybutynin once per day; from the 8th to the 42nd day, 2.5 mg twice per day; and from the 43rd day to the end of the 12th week, 5 mg, twice per day. All of the patients underwent three evaluations before and after the oxybutynin treatment (at 6 and 12 weeks), using a clinical questionnaire and a clinical protocol for quality of life (QOL). RESULTS: More than 80% of the patients experienced an improvement in palmar hyperhidrosis. Most of the patients showed improvements in their QOL (74.6%). The side effects were minor, with dry mouth being the most frequent (70.5%). CONCLUSION: The use of oxybutynin is an alternative as the first step in the treatment of palmar hyperhidrosis, given that it presents good results and improves QOL.

FUNDAMENTOS: Hiperidrose facial é uma doença que pode levar os pacientes a sérios distúrbios emocionais. A simpatectomia torácica vídeo-assistida proporciona excelente resolução da hiperidrose facial, mas está associada a algumas complicações, sendo a mais freqüente e mais importante a hiperidrose compensatória. Especialmente em pacientes submetidos à ressecção do segundo gânglio torácico, o risco de hiperidrose compensatória grave é maior, o que pode causar insatisfação com o procedimento. OBJETIVO: O objetivo deste estudo foi avaliar a eficácia e a satisfação dos pacientes com o uso da oxibutinina em doses baixas para tratar a hiperidrose facial em uma série grande de pacientes. MÉTODOS: 25 pacientes com hiperidrose facial foram tratados com oxibutinina. Os pacientes foram submetidos a duas avaliações: antes e depois do tratamento. Estas foram usadas para avaliar a melhoria clínica e a qualidade de vida. RESULTADOS: Observou-se que mais de 75 por cento dos pacientes evoluíram com melhora na hiperidrose facial, sendo que 52 por cento deles apresentaram uma grande melhora. CONCLUSÃO: O tratamento da hiperidrose facial com oxibutinina é uma boa alternativa à simpatectomia, visto que apresenta bons resultados e melhora a qualidade de vida, e os pacientes não correm o risco dos efeitos colaterais da simpatectomia.

Um minuto de grito, um lugar de paz: mulheres jovens e o direito à palavra / One minute of screaming, a peaceful place: young women and their right to talk

Pesquisando a participação de mulheres em grupos juvenis entre 1999 e 2001, pude perceber que os movimentos hip-hop e anarcopunk, apesar de se constituírem como espaços predominantemente masculinos, eram ainda espaços de relações menos hierarquizadas, onde havia uma aceitação dessas jovens mulheres, ainda que precária. 'Aberta a brecha', elas apropriavam-se dessa aceitação e transformavam-na em um discurso da valorização do 'ser mulher', denunciando as discriminações e relações desiguais que sofriam no próprio movimento, buscando construir novas relações - a partir de coletivos de mulheres ou em coletivos mistos, abrindo espaços para a atuação de outras mulheres, rompendo com os modelos tradicionais de socialização que sofreram, construindo também movimentos diferentes, em que os homens jovens estavam tendo que aprender que o poder poderia ser distribuído mais igualitariamente. A importância de sua 'juventude' estava mais em sua participação nos estilos hip-hop e anarcopunk - estilos que são juvenis -, participação que produziu os significados de gênero e raciais que elas vinham construindo, fundamentais na constituição de suas identidades (AU)

Emprego clínico da Ciclosporina em Dermatologia / Clinical use of Cyclosporine in Dermatology

A ciclosporina é droga imunossupressora de amplo uso clínico. Farmacologia, contra-indicações, efeitos colaterais, indicações atuais e perspectivas terapêuticas foram avaliadas. A ciclosporina destaca-se pela ausência relativa de mielotoxicidade, por raros efeitos corticóide-símile e antilinfocítico seletivo, e ser terapêutica alternativa efetiva em grande número de dermatoses inflamatórias e não-inflamatórias. A psoríase e a dermatite atópica permanecem sendo suas principais indicações. Entretanto, a ciclosporina mostra-se discreta no arsenal terapêutico do dermatologista, provavelmente pelas nefro e cardiotoxicidade potencialmente graves e demanda de acompanhamento rigoroso do paciente. A ciclosporina em microemulsão compartilha do mesmo perfil terapêutico, mas com menos efeitos colateriais do que a orientação tradicional
