Descrição do plexo braquial do cachorro-do-mato (Cerdocyon thous Linnaeus, 1766)

The Cerdocyon thous is a canid that has a wide distribution in South America and, besides some general aspects, its morphology is little known in the literature, especially regarding the nervous system. With the aim of elucidating the anatomical composition of brachial plexus, we studied three male specimens from Paragominas-PA, donated to the Morphological Laboratory of Animal Research (LaPMA), Federal Rural University of Amazonia (UFRA), after death by trampling. The animals were fixed in an aqueous solution of 10% formaldehyde for bilateral dissection of the origin of the brachial plexus. The brachial plexus of C. thous is derived from the last three cervical nerves and the first thoracic nerve (C6-T1). The main nerves that compose it, with their respective origins were the suprascapular nerve, subscapular nerve and musculocutaneous nerve (C6-C7), axillary nerve (C7-C8), radial nerve (C7-T1 and C7-C8), median nerve, ulnar nerve, thoracodorsal and thoracic lateral nerve (C8-T1). We conclude that the brachial plexus of C. thous is similar to that described for the domestic dogs, showing small differences in the composition of some nerves.

Tempo para acesso ao tratamento do câncer de mama no Distrito Federal, Brasil Central

PURPOSE: To analyze the time between the first symptom and treatment in patients treated for breast cancer in public hospitals in the Federal District. METHODS: This was a cross-sectional analysis. We interviewed 250 women diagnosed with breast cancer treated in six hospitals of the State Department of Health of the Federal District from November 2009 to January 2011. The time intervals studied were the time between the detection of the symptoms and treatment subdivided into intervals until and after the first medical appointment. The variables were: age, menopausal status, color, educational level, average monthly household income, origin, reason for the initial consultation, staging, tumor size, laterality, metastasis to axillary lymph nodes, neoadjuvant chemotherapy, and type of surgery. The Mann-Whtney test was used to assess the association of these variables with the time intervals until treatment. RESULTS: The mean age was 52 years, with a predominance of white women (57.6%), from the Federal District (62.4%), with a family income of up to 2 minimum wages (78%), and up to four years of schooling (52.4%). The staging of the disease ranged from II to IV in 78.8% of the women. The time between the first symptom and treatment was 229 days (median). After detection of the first symptom, 52.9% of the women attended a consultation within 30 days and 88.8% took more than 90 days to start treatment. Women with elementary school education had a greater delay to the start of treatment (p=0.049). CONCLUSIONS: There was a significant delay to start treatment of women with breast cancer in public hospitals of the Federal District, suggesting that efforts should be made to reduce the time needed to schedule medical appointments and to diagnose and treat these patients.

Punção aspirativa de linfonodo axilar guiada pela ultrassonografia é eficaz como método de predição de acometimento linfonodal em pacientes com câncer de mama?

OBJETIVO: Avaliar a viabilidade e acurácia diagnóstica da ultrassonografia pré-operatória combinada com biopsia por agulha fina (US-PAAF) e do exame clínico da axila em pacientes com câncer de mama.MÉTODOS: Neste estudo prospectivo 171 axilas de pacientes com câncer de mama foram avaliadas pelo exame clínico e ultrassonografia (US) com e sem biopsia por agulha fina (PAAF). Os linfonodos com espessura cortical maior que 2,3 mm na ultrassonografia foram considerados suspeitos e submetidos a US-PAAF.RESULTADOS: A análise de regressão logística não mostrou correlação estatisticamente significativa entre exame clínico e axilas positivas no exame patológico. Em relação à avaliação axilar com US, o risco de achados anatomopatológicos positivos aumentou 12,6 vezes, valor Kappa de Cohen foi de 0,12 para exame clínico, 0,48 para US e 0,80 para US-PAAF. A acurácia foi de 61,4% para o exame clínico, 73,1% para os US e 90,1% para US-PAAF. Análise Receiver Operating Chracteristics (ROC) mostrou que uma espessura de 2,75 mm cortical correspondeu à mais elevada sensibilidade e especificidade na predição metástase axilar (82,7 e 82,2%, respectivamente).CONCLUSÕES: A US combinada com aspiração por agulha fina é mais precisa que o exame clínico na avaliação do status axilar no pré-operatório em mulheres com câncer de mama. Aquelas que são US-PAAF positivo podem ser direcionadas para esvaziamento linfonodal axilar imediatamente, e somente aqueles que são US-PAAF negativos devem ser considerados para biópsia de linfonodo sentinela.

Hypothermia prevention during surgery: comparison between thermal mattress and thermal blanket

This study aimed to compare the efficiency of the thermal blanket and thermal mattress in the prevention of hypothermia during surgery. Thirty-eight randomized patients were divided into two groups (G1 - thermal blanket and G2 - thermal mattress). The variables studied were: length of surgery, length of stay in the post-anesthetic care unit, period without using the device after thermal induction, transport time from the operating room to post-anesthetic care unit, intraoperative fluid infusion, surgery size, anesthetic technique, age, body mass index, esophageal, axillary and operating room temperature. In G2, length of surgery and starch infusion longer was higher (both p=0.03), but no hypothermia occurred. During the surgical anesthetic procedure, the axillary temperature was higher at 120 minutes (p=0.04), and esophageal temperature was higher at 120 (p=0.002) and 180 minutes (p=0.03) and at the end of the procedure (p=0.002). The thermal mattress was more effective in preventing hypothermia during surgery.

Mensuração e análise do ph salivar em pacientes com hiperidrose submetidos a cirurgia de simpatectomia videotoracoscópica

The study was performed to verify if there are changes in salivary pH in patients with hyperhidrosis who were treated by Videothoracoscopic Sympathectomy. Twelve patients underwent sympathectomy with clamping the sympathetic chain along the vertebrae T2, T3 and T4, under inhalation and intravenous general anesthesia and with drainage of pneumothorax through probe N° 16. These patients had their saliva collected 1 day before and 7 days after surgery for measurement of pH by the colorimetric method with indicator paper. All patients showed no sign or symptom of hyperhidrosis in the immediate postoperative period, which demonstrates the success of sympathetic denervation on these levels. No patient had compensatory sweating and there was no post-operatively surgical complication. No drug or substance has been administered to patients for the study. The pH results obtained were analyzed using test ´´t´´ Student. Although the average pH in samples obtained after surgery was lower than the preoperative, the test revealed no statistically significant difference (p = 0.181). It is concluded that sympathectomy, an excellent therapeutic and definitive method for hyperhidrosis, does not alter the salivary pH, and so, did not influence the cariogenic process

Single-port retroperitoneal renal biopsy using standard urological instruments

Objective: To describe the surgical technique and initial experience with a single-port retroperitoneal renal biopsy (SPRRB).Materials and Methods: Between January and April 2013, five children underwent SPRRB in our hospital. A single 1.5 cm incision was performed under the 12th rib at mid-axillary line, and an 11 mm trocar was inserted. A nephroscope was used to identify the kidney and dissect the perirenal fat. After lower pole exposure, a laparoscopic biopsy forceps was introduced through the nephroscope working channel to collect a renal tissue sample.Results: SPRRB was successfully performed in five children. The mean operative time was 32 minutes, and mean estimated blood loss was less than 10 mL. The hospital stay of all patients was two days because they were discharged in the second postoperative day, after remaining at strict bed rest for 24 hours after the procedure. The average number of glomeruli present in the specimen was 31.Conclusion: SPRRB is a simple, safe and reliable alternative to open and videolaparoscopic approaches to surgical renal biopsy.

Benzilaminopurina e ácido naftaleno acético na indução e multiplicação in vitro de gemas de abacaxizeiro da cultivar 'IAC Gomo-de-mel'

O objetivo deste trabalho foi avaliar os efeitos de BAP (6-benzilaminopurina) e NAA (ácido naftaleno acético) na indução, na multiplicação in vitro de gemas, nas brotações de Ananas comosus da cultivar 'IAC Gomo-de-mel' e a correlação desses efeitos com a atividade de peroxidase e o teor de proteína solúvel total. Foram utilizadas gemas axilares retiradas da coroa de frutos sadios, inoculadas em tubo de ensaio contendo meio de cultura MS solidificado com ágar a 5%, pH ajustado para 5,7, contendo os tratamentos que incluíam diferentes concentrações e combinações de BAP (0, 0,5, 1,0 e 1,5mg L-1) e NAA (0, 0,5 e 1,0mg L-1). Nessa fase, aos 65 dias, ocorreu a formação de 2,24 brotações, utilizando-se 1mg L-1 de BAP. Após o desenvolvimento, as gemas foram inoculadas em meio MS líquido associado a dois tratamentos (1,0mg L-1 BAP + 0,5mg L-1 NAA e 1,0mg L-1 BAP + 1,0mg L-1 NAA) e, aos 95 dias, o meio de cultura mais adequado foi aquele que continha 1,0mg L-1 BAP + 0,5mg L-1 NAA, proporcionando 7,42 brotações, menor porcentagem de hiper-hidricidade, maior número de brotações e indução de gemas. As proteínas solúveis apresentaram relação negativa com hiper-hidricidade e comprimento de brotações. A atividade da peroxidase foi maior em plantas com maior número de brotos e com maior porcentagem de hiper-hidricidade.
