Surgery patients in Japan undergo routine spirometry testing prior to general anesthesia. The use of a flow sensor during general anesthesia has recently become common. However, it is not certain whether the information derived from flow-volume curves is being adequately used for mechanical ventilation management during general anesthesia. So far, there have been no attempts to calculate airway resistance using flow-volume curves. Therefore, we performed a prospective, observational study to investigate the relationship between pre-anesthetic and intra-anesthetic airway resistance in patients scheduled for surgery under general anesthesia...

BACKGROUND: Nursing burnout is affected by various factors, including work overload. Since the inauguration of the Health Sector Evolution Plan (HSEP) in Iran in 2014, government hospitals have been required to provide health services to the public at all levels. This decision, however, has increased the volume of patients admitted to government hospitals. Because nurses are on the front line of health services, they are faced with a greater load of care provision. PURPOSE: This study aimed to evaluate nursing burnout before and after HSEP in Iran, with an emphasis on the differences between government and private hospitals...

The importance of deadwood (DW) in forest ecosystems is widely recognized today. Deadwood is used as a proxy indicator for biodiversity conservation and sustainable management of forests. This research aims to determine the amount and spatial distribution of DW (standing dead trees, stumps, and coarse woody debris) and characterize the changes with few selected parameters in an unmanaged forest reserve of Köprülü Canyon National Park (NP). The data were collected from 387 temporary sample plots with different stand characteristics such as stand age, crown closure, site index, and density, and site parameters like elevation, aspect, slope, and distance to settlement areas of Calabrian pine (Pinus brutia Ten...

BACKGROUND: Handling of breast specimen is not well monitored and there is limited data on the impact of fixative solutions on specimen weights. Weight of resected breast tissue acts as a guide for future reconstructive and symmetrisation procedures. The aim is to quantitatively evaluate the discrepancies in weight of fresh breast specimen and the weight of specimen after being kept in a fixative solution for a variable length of time. METHODS: Single centre retrospective cohort study including patients undergone breast surgery for both diagnostic and therapeutic purposes between January of 2013 and June 2015...

BACKGROUND: When the permeability of the glomerular filtration barrier increases, leading to proteinuria, nephrotic syndrome (NS) occurs. First episodes or relapses of NS can be concurrent with acute gastroenteritis (AGE) infections. This condition can cause further deterioration of the hypovolemic state, as intravascular water is lost through both AGE-related vomiting/diarrhea and NS-related fluid shifting into the interstitium. In this case report, we wish to raise the issues about the difficult management of children presenting with both NS and AGE...

Emerging technology designed to kill mosquito larvae with sound waves may present a nonchemical and nonbiological alternative to reduce larval populations of key medically important mosquito species such as Aedes aegypti in containers or catchments of water. These devices could benefit integrated vector management programs facing public resistance to the use of chemical or biological larvicides in stored drinking water. In this study we investigate the efficacy of a Larvasonic SD-Mini Acoustic Larvicide device in reducing larval populations of Ae...

OBJECTIVES: Certain patients ultimately undergo explantation of their spinal cord stimulation (SCS) devices. Understanding the predictors and rates of SCS explantation has important implications for healthcare resource utilization (HCRU) and pain management. The present study identifies explant predictors and discerns differences in HCRU for at-risk populations. METHODS: We designed a large, retrospective analysis using the Truven MarketScan Database. We included all adult patients who underwent a SCS trial from 2007 to 2012...

INTRODUCTION: Surgical treatment of Grade III gynecomastia generally utilizes mastectomy techniques and free transplantation of the nipple-areola complex. Moreover, with rising obesity rates and the development of bariatric surgery, an increasing demand for correctional surgery for pseudogynecomastia has been observed, which is comparable to Grade III gynecomastia in terms of its surgical management. Here, we describe an innovative technique to deal with these new demands: fascio-cutaneous flap by postero-inferior pedicle...

Cirrhotic patients with refractory ascites (RA) can be treated with repeated large volume paracentesis (LVP), with the insertion of a transjugular intrahepatic portosystemic shunt (TIPS) or with liver transplantation. However, side effects and complications of these therapeutic options, as well as organ shortage, warrant the development of novel treatments. The automated low-flow ascites pump (alfapump(®)) is a subcutaneously-implanted novel battery-driven device that pumps ascitic fluid from the peritoneal cavity into the urinary bladder...

Contrast-induced encephalopathy (CIE) is an acute and reversible neurological disturbance associated with the intra-arterial administration of iodinated contrast medium during cardiac catheterisation. It may manifest with encephalopathy, motor and sensory disturbances; vision disturbances, including cortical blindness, ophthalmoplegia, aphasia; and seizures. Disruption of the blood-brain barrier and direct neuronal toxicity are believed to be implicated in the pathophysiology of the syndrome. Symptoms appear soon after contrast administration and resolve completely within 24-48 h...

: Inspired Oxygenation in Surgical Patients During General Anesthesia With Controlled Ventilation: A Concept of Atelectasis. By Bendixen HH, Hedley-Whyte J, and Laver MB. New Engl J Med 1963; 269:991-996. Reprinted with permission. ABSTRACT: The purpose of this study was to determine if the pattern of ventilation, by itself, influences oxygenation during anesthesia and surgery and examine the hypothesis that progressive pulmonary atelectasis may occur during constant ventilation whenever periodic hyperventilation is lacking, but is reversible by passive hyperinflation of the lungs...

Two cases of patients that developed right ventricular failure (RVF) after cardiac valve surgery are presented with a narrative revision of the literature. RVF involves a great challenge due to the severity of this condition; it has a low incidence among non-congenital cardiac surgery patients, is more likely associated with cardiovascular and pulmonary complications related to cardiopulmonary bypass (CPB), and is a cause of acute graft failure and of a higher early mortality in cardiac transplant. The morphologic and hemodynamic characteristics of the right ventricle and some specific factors that breed pulmonary hypertension after cardiac surgery are in favor of the onset of RVF...

Rashmi Ramachandran, Vimi Rewari
Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, (123)I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging...

REVIEW

Liver metastases from breast cancer (LMBC) have long been considered as a systemic disease because of the hematological route of dissemination, requiring noncurative management. In fact, despite recent advances in drug therapies personalized to tumor phenotype, the chances of a cure are nil and there is little hope of long-term survivors after nonsurgical management alone. By contrast, there is a growing evidence in the literature for satisfactory long-term results after a combination of chemotherapy and liver resection, with 5-year survival reaching >40% in some series...
