Upper-Extremity Blocks

1988

Brachial plexus block was first performed in 1885 by William Steward Halsted, who used cocaine and direct exposure of the roots in the neck to accomplish the block. In 1911, Hirschel and Kulenkampff described the first percutaneous brachial plexus block by the axillary and supraclavicular routes respectively. Since these historic reports, the efficacy of brachial plexus block has been confirmed, and the block is now commonly used to provide upperextremity anesthesia.

Rolipram inhibits airway microvascular leakage induced by platelet-activating factor, histamine and bradykinin in guinea-pigs.

1993

Abstract Rolipram (0·1–1000 μg kg−1, i.v.) reduced the increase in microvascular permeability induced by platelet-activating factor (PAF; 50 ng kg−1, i.v.) at different sites of the guinea-pig airways. Rolipram (1–100μg kg−1, i.v.) inhibited histamine (30μg kg−1, i.v.)-and bradykinin (0·3 μg kg, i.v.)-induced airway microvascular leakage. These effects of rolipram were obtained at doses which inhibit histamine (7–20 μg kg−1 min−1)-induced bronchoconstriction (IC50 = 3 ± 1 μg kg, i.v.) without depressing arterial blood pressure in the guinea-pig. Aminophylline (50 mg kg−1) did not change the effect of PAF. The anti-exudative effect of rolipram is of potential therapeutic value in asthma.

ROLIPRAM INHIBITS PAF-INDUCED AIRWAY MICROVASCULAR LEAKAGE IN GUINEA-PIG - A COMPARISON WITH MILRINONE AND THEOPHYLLINE

1992

The effects of 3 phosphodiesterase (PDE) inhibitors, rolipram (PDE IV), milrinone (PDE III) and theophylline (non-selective) on PAF (50 ng kg-1; iv)-induced airway vascular leakage have been evaluated in guinea-pigs. Rolipram (3-300 micrograms kg-1; iv) reduced the increase in permeability induced by PAF at all airway levels whereas milrinone (10-1000 micrograms kg-1; iv) and theophylline (30 mg kg-1; iv) were without effects. The anti-leakage activity of rolipram may be of therapeutic value in asthma.

Giant enchondroma recurrence of the proximal phalanx of the fifth finger: A case report

2020

Enchondroma (EC) is a benign and cartilage-forming tumor that causes intramedullary lesions. Moreover, EC is the most common bone tumor in the phalanges and metacarpal bones of the hand, deforming the structure and causing pain and functional limitation. The management of this neoplasia is the surgical treatment and the approach that is well-accepted consists in the curettage followed by the void augmentation with biological or synthetic fillers. The results from surgery are usually good and the recurrence rate is low (2-15%). In this article we report a case of EC recurrence of the proximal phalanx of the fifth finger of the hand after curettage and grafting. The patient was treated with t…

"Doctor, tengo un bulto en la axila". Adenomegalia siliconomatosa postmamoplastia de aumento: a propósito de ocho casos

2010

La aparición de adenopatías axilares asociadas a mamoplastia de aumento mediante prótesis de silicona es un hecho infrecuente, no excepcional, y muy preocupante para paciente y cirujano. Hemos hecho una revisión de 1697 historias clínicas de pacientes sometidas a mamoplastia de aumento mediante prótesis de silicona al objeto de estudiar la relación entre roturas protésicas y adenopatías axilares Las 1697 pacientes se dividieron en grupos que cumplían 1, 2, 3, 5 y 7 años de haber sido intervenidas. Revisamos sus historias clínicas y estudiamos las que con posterioridad a la cirugía habían consultado por sospecha de rotura protésica y adenopatías axilares. No encontramos roturas protésicas an…

Onkoplastische Sofortrekonstruktions-Technik unter Erhalt des Mamillen-Areola-Komplexes nach radikaler Resektion eines Mammakarzinoms mit zentralem S…

There are few breast-conserving therapies (BCT) for centrally located breast cancer. The present paper describes a BCT for breast cancers in such a location, which permits conservation of the nipple-areola complex (NAC), provided this has not been infiltrated. After histological detection of the breast cancer by punch biopsy, a central segmental mastectomy and an axillary dissection are performed. An immediate reconstruction of the subareolar defect is carried out by means of a local flap technique, thus conserving the NAC.

Effects of the number of removed lymph nodes on survival outcome in patients with sentinel node-negative breast cancer.

2021

Abstract Background Sentinel lymph node biopsy is the gold standard surgical technique for axillary staging in patients with clinically node-negative. However, it is still uncertain what is the optimal number of sentinel lymph nodes (SLNs) to be removed to reduce the false-negative rate. The aim of this study was to investigate whether patients with a single negative SLN have a worse prognosis than those with two or more negative SLNs. Methods A retrospective review was conducted on a large series of SLN-negative breast cancer patients. Survival outcomes and regional recurrence rate were evaluated according to the number of removed SLNs. Secondly, the contribution of different adjuvant ther…

OC2.01: Examination of the fetal brain by three-dimensional ultrasound: potential for routine neurosonographic studies

2005

Objective: To evaluate the role of three-dimensional (3D) ultrasound in the assessment of the fetal brain and its potential for routine neurosonographic studies. Methods: We studied prospectively 202 consecutive brain fetuses between 16 and 24 weeks’ gestation. A 3D-ultrasound volume of the fetal head was acquired transabdominally. The entire brain anatomy was later analyzed by a sonologist expert in neonatal cranial sonography using the multiplanar images. The quality of the conventional planes obtained (coronal, sagittal and axial, at different levels) and the ability to visualize properly the major brain anatomic structures were evaluated. Results: Acceptable rendered cerebral volumes we…

Kinin receptors in human vascular tissue: their role in atheromatous disease

1997

Using samples of many human blood vessels, obtained at autopsy and specific antibodies directed to peptide sequences of the kinin B1 and B2 receptors, we demonstrate the localisation of these receptors within the human vascular system using standard immunolabelling techniques. In large elastic arteries and veins, kinin receptors are present only in the endothelial cells whereas in all muscular arteries and arterioles, these receptors are present in both the endothelial and smooth muscle cells. The identification of kinin receptors in human blood vessels confirms that kinins may modulate both vascular permeability and contractility. The incidental finding at histology, of patchy atheromatous…
