IN 1928 Dotterweich published under the title " Beitrage zur Nervenphysiologie der Insekten" some very interesting and important observations and measurements mainly on Sphingidae, showing that the rapid vibration of the wings regularly observed in large moths before they take flight produces an increase in temperature of the wing muscles which is necessary to enable them to fly at all. The tem...

Observations and measurements are reported on the patterns and rates of growth in time of the double-diffusive cells that form adjacent to a cooled sidewall in a saltstratified environment. Fluid near the wall is cooled and sinks a distance h where its density, increased by cooling, matches that of the salt-stratified ambient. The fluid separates from the wall, moving outwards as a cool, freshe...

Intraoperative neurophysiological monitoring (IONM) makes it possible to determine the status of neurological function during surgery. It guides the surgeon and minimises the risk of injury. This paper describes the different techniques available for IONM in spine surgery (somatosensory evoked potentials, motor evoked potentials, neurography, electromyography, reflexes and dermatomic evoked pot...

Dear Editor, I have greatly enjoyed reading the case report entitled “‘Femoral Condyle Fracture during Revision of Anterior Cruciate Ligament Reconstruction: Case Report and a Review of Literature” in the issue of Arch Bone Jt Surg.2015; 3(2):137-40 with great interest. I would like to commend the authors for their detailed and valuable work. Although various case reports have described postope...

OBJECTIVE Design features of intraoperative probes are presented. A brief discussion of the sentinel node concept and relevant radiopharmaceuticals is given. The importance of the injection technique and the necessity of imaging in radiotracer techniques for sentinel node detection are explained. Probe calibration, procedural precautions, intraoperative techniques, and radiation dosimetry relev...

INTRODUCTION Ultrasound can visualize and update the vessel status in real time during cerebral vascular surgery. We studied the depiction of parent vessels and aneurysms with a high-resolution 3D intraoperative ultrasound imaging system during aneurysm clipping using rotational digital subtraction angiography as a reference. METHODS We analyzed 3D intraoperative ultrasound in 39 patients wit...

We retrospectively examined intraoperative blood transfusion patterns at US veteran's hospitals through description of national patterns of intraoperative blood transfusion by indication for transfusion in the elderly; assessment of temporal trends in the use of intraoperative blood transfusion; and relationship of institutional use of intraoperative blood transfusion to hospital 30-day risk-ad...

BACKGROUND The exact assessment of a tonsil carcinoma's size is often difficult because of the tumour's submucosal extension and deep infiltration. AIM The aim of the study is to assess the usefulness of intraoperative ultrasonography in tonsil cancer. MATERIAL Twenty patients with carcinoma of the tonsil were included in the study (squamous cell carcinoma keratosis - 12, squamous cell carc...

The objective of this study was to compare the intraoperative time, intraoperative blood loss and post operative pain between coblation tonsillectomy and cold tonsillectomy in the same patient. A prospective single blind control trial was carried out on 34 patients whom underwent tonsillectomy. The patients with known bleeding disorder, history of unilateral peritonsillar abscess and unilateral...
