introduction: tonsillectomy is one of the most common surgeries all over the world and is performed by various methods. this study aimed to investigate the complications of bipolar electrocautery method of tonsillectomy. methods: this cross-sectional study was performed on 234 patients, 114 female and 120 male individuals. the mean age of the patients was 12.2±8.3 (min=3 and max=58.2) years. so...

PURPOSE To compare single-site intraoperative sarcomere length values with sarcomere lengths measured from systematic sampling of the entire transferred muscle. METHODS The tendon of the rabbit second toe extensor muscle was transposed to the ankle extensor retinaculum under levels of stretch over the sarcomere length range of about 2.5 microm to about 4.0 microm. Intraoperative sarcomere len...

OBJECTIVES To compare surgeons' interpretations of intraoperative diagnoses with those rendered by the pathologist. METHODS Consecutive intraoperative diagnoses over a nine-month period were retrospectively reviewed. For each case, operative notes were obtained from the hospital information system. The intraoperative diagnoses listed in the final pathology reports were compared with those dic...

BACKGROUND Parathyroid lipoadenoma is an uncommon tumor that may be difficult to diagnose on intraoperative frozen section. Intraoperative parathyroid hormone (PTH) measurement is useful in assessing the adequacy of parathyroidectomy. This case demonstrates the value of intraoperative PTH measurement in recognizing a parathyroid lipoadenoma. METHODS AND RESULTS A case of a 62-year-old woman w...

BACKGROUND Three-dimensional (3D) imaging with a mobile C-arm has proven to be a valuable intraoperative tool in trauma surgery. However, little data is available concerning its use in the treatment of elbow fractures. The aim of the current study was to determine the intraoperative findings and consequences of 3D imaging in the treatment of elbow fractures. METHODS Between 2001 and 2015, pro...

BACKGROUND AND PURPOSE Resting-state functional MR imaging has been used for motor mapping in presurgical planning but never used intraoperatively. This study aimed to investigate the feasibility of applying intraoperative resting-state functional MR imaging for the safe resection of gliomas using real-time motor cortex mapping during an operation. MATERIALS AND METHODS Using interventional M...

Observations of the evolution of species groups in nature, such as well recognized Galapagos finches, have motivated much theoretical research aimed at understanding the processes associated with such radiations. The Penna model is one such model and has been widely used to study aging. In this paper we use the basic Penna model to investigate the process of sympatric speciation in a simple foo...

BACKGROUND Remifentanil enhances intraoperative hemodynamic stability, suggesting that it may decrease intraoperative blood loss when included as an adjuvant to general anesthesia. This retrospective study compared intraoperative blood loss during spinal surgery in patients administered either remifentanil or fentanyl as an opioid adjuvant. METHODS We reviewed clinical and surgical data from ...

INTRODUCTION The treatment of primary hyperparathyroidism consists almost exclusively in the parathyroidectomy. The preoperative imaging (ultrasonography, 99mTc sestamibi scan) can allow to localize the pathologic gland and perform minimally-invasive focused techniques, but in presence of ectopic or intrathyroidal glands, parathyroid hyperplasia or coexistent thyroid disease, the sensitivity of...
