Venous leg ulcers represent a significant public health problem that will increase as the population ages. Numerous herbs and their extracts are potentially conducive to wound healing, including the ability to serve as an antimicrobial, antifungal, astringent, etc. A total of 32 patients with venous leg ulcers were randomized into two groups: a group with herbal therapy treatment (PT) (17 patients) and a control group (C) (15 patients). The investigation focused on five controls of parameter changes important for ulcer healing and the control of microbiological flora. Within-treatment analysis of the PT group showed that, following herbal therapy treatment, there was a significant decrease in the scores of surface leg ulcer and venous leg ulcer after week 7 of treatment (p < 0.05). In group C following topical antibiotic treatment there was no significant decrease in the surface leg ulcer. Comparing the results of decreased venous leg ulcer surface of the) PT group with the C group showed a significant difference at p < 0.05 after week 7 of treatment. The number of different types of isolated bacterial species decreased significantly (p < 0.05) after the use of herbal preparations. The results of this pilot study demonstrate the healing and antimicrobiological effects of herbal therapy on non-infected venous leg ulcer.
Introduction: Basal cell carcinoma is the most common tumor of the eyelid. In this region, reconstruction is complex and damage to healthy tissue should be minimal. Objective: To define the relationship between margin clearance at excision and the recurrence rate of basal cell carcinoma of the eyelid. Methods: This prospective study was conducted with 111 patients submitted to surgery for basal cell carcinoma of the eyelid between 2001 and 2003 and followed up for a period of five years. The patients were evaluated according to age, tumor site, recurrence rate and margin clearance at excision. Results: No significant association was found between incomplete tumor excision and recurrence except in patients under 56 years of age, female patients and in the case of tumors of the medial canthus. Conclusion: A risk of recurrence in incompletely excised basal cell carcinomas of the eyelid was only confirmed in younger patients, females and for tumors of the medial canthus. Keywords: Basal cell carcinoma; eyelid; recurrence.Resumo: Introdução: O carcinoma basocelular é o tumor mais comum entre os tumores das pálpebras. Nesta região, a reconstrução é complexa e recomenda-se que haja perda mínima de tecido saudável. Objetivo: Para definir a relação entre margem livre de tumor na excisão e taxa de recidiva do carcinoma basocelular das pálpebras. Métodos: Este estudo prospectivo incluiu 111 pacientes operados para remoção de carcinoma basocelular das pálpebras no período de 2001 a 2003, com acompanhamento subsequente de 5 anos. Os pacientes foram avaliados de acordo com a idade, localização do tumor, taxa de recidiva, e margem livre de tumor na excisão. Resultados: Não se encontrou associação significativa entre a excisão incompleta do tumor e casos de recidiva, exceto em pacientes com idade inferior a 56 anos, pacientes do sexo feminino e em tumores do canto medial. Conclusão: Um risco maior de recidiva de carcinoma basocelular das pálpebras com excisão incompleta foi confirmado estatisticamente apenas em pacientes mais jovens, em mulheres, e nos tumores do canto interno.
Segmental neurofibromatosis is a rare clinical finding generally with no family
history and facial involvement. There are four subtypes of segmental
neurofibromatosis: true segmental, localized cases with deep involvement, hereditary
segmental and bilateral segmental neurofibromatosis. Here we report three patients
from the same family (father, son and granddaughter) with segmental bilateral
neurofibromatosis on the face. This form hasn't noticed in the literature.
Basosquamous carcinoma of the skin is a relatively rare cutaneous neoplasm that has significant metastatic potential and a metastatic rate greater than that of basal cell and squamous cell carcinoma. We describe the use of lymphatic mapping and sentinel lymph node biopsy in a 63-year-old man after identification of basosquamous carcinoma. Sentinel lymph node biopsy, which is a standard tool to detect regional lymphatic metastasis in cutaneous melanoma, has been rarely employed to detect lymphatic metastasis of basosquamous carcinoma. The approach was successful in detecting a regional lymphatic metastasis of two nodal basins with minor morbidity. Sentinel lymph node biopsy may be useful for certain high-risk lesions of basosquamous carcinoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
