ABSTRACT
BACKGROUND@#Small pulmonary nodules are usually difficult to identify during thoraco-scopic resection, and preoperative computed tomography (CT)-guided percutaneous puncture assisted localization can be helpful. The purpose of this study is to compare the localization effect and complication rates of two different methods by microcoil placement and sclerosing agent injection (Lauromacrogol).@*METHODS@#A retrospective analysis of the clinical data of 371 patients with preoperative pulmonary nodules percutane us puncture localization was performed. According to the use of different materials, they were divided into the microcoil group (167 cases with 196 localized nodules ) and the sclerosing agent group (204 cases with 239 localized nodules). The localization effect, complication, pathological results and operation relates data were statistically analyzed.@*RESULTS@#The localization failure rate (2.4%) was higher in the microcoil group than in the sclerosing agent group (0.5%) (P=0.011), and the localization time of sclerosing agent group was significantly shorter than the microcoil group [(18.78±6.91) min vs (11.99±3.77) min, P=0.000], but the distance between the selected localized nodules and the pleura was deeper in the microcoil group than in the sclerosing agent group [(9.59±8.62) mm vs (8.13±6.49)mm, P=0.002]. The overall complications in the microcoil group were significantly higher than those in the sclerosing agent group (P=0.000), in which pneumothorax was the most common. Through the analysis of related risk factors, we revealed that different positioning methods was independent risk factors. Wedge resection was the main type of surgical method and non-invasive carcinomas were the majority of postoperative pathological results.@*CONCLUSIONS@#Our study suggests that both microcoil placement and sclerosing agent injection are suitable for preoperative pulmonary nodule localization equivalently, however, compared with microcoils placement, injection of lauromacrogol, the sclerosing agent, had lower failure rate, less complications, shorter localization time and it is worthy of promotion also by easy operation and low cost.
ABSTRACT
Orchiectomized bulls have advantages in the meat quality and ease of handling. Chemical castration is an option for surgical castration and the sclerosing agents can be administered into the testicular or epididymis parenchyma. These agents have a lower incidence of complications than surgery, especially when associated with dimethylsulfoxide (DMSO), which has anti-inflammatory action and increases the absorption of other drugs. Thus, this study aimed to evaluate the effect of a single intratesticular injection of calcium chloride solution associated with DMSO for the chemical sterilization of bulls. Twenty-four young adult bulls were utilized, distributed into 3 groups (G20, G30 and G40, n = 8/group), according to the calcium chloride concentration (20, 30 and 40%), in 10mL volume. Serum concentrations of testosterone, body weight, testicular volume and ecotexture, clinical signs and behavior and were evaluated for 45 days. Thus, the animals were orchiectomized and testicles were assessed histologically. There were no changes in body weight, decreased serum testosterone concentrations (except G30), signs of scrotal sensitivity or changes in behavior over the period. However, there was significant increase in testicular volume, especially on the 2nd and 3rd day after treatment, with values returning to the value initials at 15 days. Testicular adherence and firm consistency were observed during orchiectomy. Ultrasound examination revealed a loss of integrity of the median raphe, with cavity formation and an alteration of the testicular echotexture. In the histological evaluation, coagulation necrosis of seminiferous tubules and interstitial cells was observed, mainly in the medial portion in all groups. Some animals presented total absence of tubular formations in all the studied groups, being the effects of greater intensity in the G40. Additionally, pronounced edema was noted in all groups, especially in G40. Inflammatory infiltrate, fibroplasia and neovascularization were found to be predominantly discrete. Based on the conditions used in this study, we conclude that calcium chloride associated with DMSO can be used as a method of chemical sterilization in bovines.(AU)
Bovinos orquiectomizados apresentam vantagens na qualidade da carne e facilidade no manejo. A quimioesterilização é uma opção à castração cirúrgica e os agentes esclerosantes podem ser administrados no parênquima testicular ou epidídimo. Estes produtos possuem menor incidência de complicações, comparados a cirurgia, especialmente quando associados ao dimetilsulfóxido (DMSO), que apresenta ação anti-inflamatória e aumenta a absorção de outros fármacos. Assim, este estudo teve como objetivo avaliar o efeito de uma única injeção intratesticular de solução de cloreto de cálcio associado com 0,5% de DMSO para a esterilização química de bovinos. Vinte e quatro touros adultos jovens foram utilizados, distribuídos em 3 grupos (G20, G30 e G40, n = 8/grupo) de acordo com a concentração de cloreto de cálcio (20, 30 e 40%), em um volume de 10mL. Foram avaliadas as concentrações séricas de testosterona, peso corporal, volume e ecotextura testicular, sinais clínicos e comportamento por 45 dias. A seguir, os animais foram submetidos à orquiectomia e os testículos avaliados histologicamente. Não foram observadas alterações do peso corporal, diminuição das concentrações de testosterona sérica (exceto no G30), sinais de sensibilidade escrotal ou alterações no comportamento no período avaliado. Porém, houve aumento significativo do volume testicular, especialmente nos 2º e 3º dia após o tratamento, com valores retornando aos iniciais aos 15 dias. Aderência e consistência firme dos testículos foram achados observados durante a orquiectomia. O exame ultrassonográfico revelou perda de integridade da rafe mediana, com formação de cavidades e alteração da ecotextura testicular. Na avaliação histológica, verificou-se necrose de coagulação de túbulos seminíferos e células intersticiais acentuada, principalmente, na porção medial em todos os grupos, sendo que em alguns animais havia ausência total das formações tubulares em todos os grupos estudados, sendo os efeitos de maior intensidade no G40. Além disso, edema foi acentuado em todos os grupos, principalmente em G40. Infiltrado inflamatório, fibroplasia e neovascularização foram achados predominantemente discretos. Com base nas condições utilizadas neste estudo, conclui-se que o cloreto de cálcio associado com o DMSO pode ser utilizado como um método de esterilização química em bovinos.(AU)

ABSTRACT
Objective To discuss the application of endoscopic injection of lauromacrogol and methylene blue in sclerotherapy of esophageal varices. Methods The clinical data of 62 patients with esophageal varices underwent endoscopic treatment from June 2014 to February 2016 were collected, including 26 cases treated by endoscopic injection of lauromacrogol (A group) and 36 cases treated by endoscopic injection of lauromacrogol and methylene blue (B group). The treatment effects, success rate of hemostasis, safety, complications and follow-up recurrence were compared between the two groups. Results The total effective rate and success rate of emergency hemostasis in B group were slightly higher than those in A group (P > 0.05). The times of treatment for eliminating esophageal varices in B group was less than that in A group, and the duration of treatment was shorter than that in A group (P < 0.05). The long-term rebleeding rate and total bleeding rate in B group were lower than those in A group (P < 0.05). The incidence of postoperative complications and recurrence rate in B group were lower than those in A group (P < 0.05). Conclusion Endoscopic injection of lauromacrogol and methylene blue is effective in the treatment of esophageal varices, and the hemostatic effect is good. The incidence of postoperative complications and the recurrence rate are low.

ABSTRACT
INTRODUÇÃO: A escleroterapia é um dos procedimentos mais realizados pelos angiologistas e cirurgiões vasculares brasileiros. O princípio básico é eliminar a veia varicosa, destruindo a sua parede interna. No Brasil, há uma diversidade de condutas que envolvem este tratamento, principalmente quanto ao tipo de esclerosante, associação com laser, uso de luva durante o procedimento, tempo recomendado de repouso, exposição ao sol, prática de atividade física, uso de compressão pós-escleroterapia, entre outros. OBJETIVO: conhecer as mais variadas condutas e técnicas desta modalidade terapêutica, muito praticada entre os angiologistas brasileiros. MÉTODO: A pesquisa foi realizada entre angiologistas membros da Sociedade Brasileira de Angiologia e Cirurgia Vascular - SBACV, que responderam um questionário sobre as técnicas e indicações da escleroterapia em varizes dos membros inferiores no Brasil. O link (www.iniciacaocientica.com.br/pne) foi disponibilizado com questões de múltipla escolha. RESULTADOS: Duzentos e trinta e dois médicos responderam ao questionário proposto. Luvas durante o procedimento são usadas por 79,74% dos médicos; a compressão é utilizada por 52,59%; quanto à atividade física pós-escleroterapia, 46,12% não restringem e 52,59% liberam após 1 a 3 dias; mecanismos para diminuir a dor durante o procedimento são utilizado por 43,53% dos entrevistados; a glicose 75% foi o esclerosante mais utilizado em 35,34%; a complicação sistêmica mais frequente foi a lipotimia com 7,76% e o local mais frequente foi a hipercromia com 66,38%; em relação à liberação para sol depois do procedimento: 28,02% liberam após a escleroterapia com filtro solar, 24,57% liberam após 15 a 30 dias e 25,43% liberam com menos de 15 dias. CONCLUSÃO: A pesquisa revelou que, apesar da escleroterapia ser amplamente utilizada na prática diária do angiologista brasileiro, há pouca concordância em pontos relevantes, como, por exemplo, o uso de compressão, liberação para atividade física e exposição ao sol.
INTRODUCTION: Sclerotherapy is one the most performed procedures by Brazilian vascular surgeons and angiologists. The basic principle is to eliminate the varicose vein, destroying its internal wall. In Brazil, there is a range of practices involved in this treatment especially regarding the sclerosing type, association with laser, use of gloves during the procedure, recommended resting time, sun exposure, practice of physical activity, use of post-sclerotherapy compression, among others. OBJECTIVE: To obtain knowledge on the most varied practices and techniques of this therapeutic modality, widely practiced by Brazilian angiologists. METHODS: The survey was carried out among approximately 3 thousand Brazilian angiologists, members of the Brazilian Society of Angiology and Vascular Surgery - SBACV. The physicians answered an e-mail questionnaire on the techniques and indications of sclerotherapy of the lower limb varicose veins in Brazil. The link (www.iniciacaocientifica.com.br/pne) was made available with multiple choice questions. RESULTS: The questionnaire submitted was answered by 232 physicians. Gloves were worn during the procedure by 79.74% of the physicians; compression was employed by 52.59%; regarding physical activity after sclerotherapy , 46.12% of the physicians did not restrict, while 52.59% of them approved exercise after 1-3 days; ways to reduce pain during the procedure were used by 43.53% of the respondents; glucose 75% turned out to be the sclerosing agent most used by 35.34%; the most frequent systemic complication was lipothymia at 7.76%, and the most frequent local complication was hyperchromia at 66.38%; regarding sun exposure after the procedure: 28.02% released after the sclerotherapy with sunscreen, 24.57% after 15-30 days, and 25.43% after a period less than 15 days. CONCLUSION: Despite the fact that sclerotherapy is widely employed by Brazilian angiologists in their daily practice, the survey has shown little agreement in relevant points, such as the use of compression, release for physical activities, and sun exposure.

Venous lakes are small, dark blue, slightly raised, soft lesions occurring on the exposed skin of an elderly person. The face, ears, lips, neck, forearms and backs of hands are common sites. Histopathologic findings show either one greatly dilated space or several interconnected dilated spaces filled with erythrocytes and lined by a single layer of flattened endothelial cells in the upper dermis. We report two cases of venous lake treated with sodium tetradecyl sulfate (STS) which is one of sclerosing agents. The lesions was almost disappeared and no side effects were observed. The two cases showed no recurrence.

Objective To investigate the feasibility of sclerosing agent injection in the treatment of benign thyroid cysts. Methods Clinical data of 60 patients with thyroid cysts, who had been treated by injection of absolute alcohol or 10% sodium chloride solution, were reviewed retrospectively. Results A total of 74 lesions existed in 60 patients, and 182 times of injection were performed, with a total cure rate of 98 3% (59/60). No complications occurred. Follow-up observations for 1～5 years (mean 2 years) found no recurrence. Conclusions Sclerosing agent injection is a feasible method for benign thyroid cysts, if an exclusion of cystic papillary carcinoma is made.
ABSTRACT
To evaluate the sclerotic effects and skin damage of varicose sclerosing agents such as polidocanol, sodium tetradecyl sulfate, hypertonic saline, ethanolamine oleate, these agents were injected into rabbit ear vein and subcutaneous tissue, and the tissue specimens were obtained after 3 hours and 24 hours. The results were as follows. 1) The detergent sclerosing agents (polidocanol, sodium tetradecyl sulfate and ethanolamine sulfate) have strong sclerosing effect and showed the difference in effect according to their concentration, and the skin change was more severe than osmotic agent. 2) The sclerosing effect of osmotic agent (hypertonic saline) was equal to or somewhat less than that of detergent sclerosing agents, but the skin change was minimal. Therefore in the sclerotherapy of early phase varicose vein and telangiectasia, use of osmotic agent (23.4% hypertonic saline) or diluted detergent sclerosing agents (0.75% polidocanol, 0.25% sodium tetradecyl sulfate and 1.5% ethanolamine oleate) might be safe, but in case of more advanced varicose vein, the detergent sclerosing agents (1% polidocanol, 0.5% sodium tetradecyl sulfate and 3% ethanolamine oleate), which have strong sclerosing effect, might be useful.
