Left Ventricular Rhabdomyoma With Severe Left Ventricular Outflow Tract Obstruction

JOURNAL OF CARDIAC SURGERY, Issue 5 2007
Ali Sarigul M.D.
Rhabdomyomas are the most common tumors in this group of patients. We herein report a 40-day-old male patient with left ventricular rhabdomyoma. The tumor caused syncope attack and supraventricular tachycardia. An emergency operation was planned and the life-threatening lesion was excised via left ventriculotomy. The patient was extubated on postoperative sixth hour and discharged from hospital on the sixth day of the postoperative period without any problem. This successful operation encourages us not to hesitate to perform an operation in newborns with cardiac neoplasms causing hemodynamic instability. [source]


Design of forming shoulders with complex cross-sections

PACKAGING TECHNOLOGY AND SCIENCE, Issue 4 2005
C. J. McPherson
Abstract Vertical ,form, fill and seal' machines are used to produce bags for packing particulate or multiple objects. In operation, film is drawn over a forming shoulder and the good design of the surfaces of the shoulder is vital to the successful operation. This paper reviews underlying geometrical definition for the shoulder, corresponding to a filling tube with circular cross-section. In practice, such cross-sections occur frequently, but other variant shapes are becoming increasingly common. A method is discussed and demonstrated for extending the approach to allow tubes formed from circular arcs and straight line segments to be handled. Copyright © 2005 John Wiley & Sons, Ltd.

Psychiatric and psychological outcomes of Japanese living donors following liver transplantation

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 4 2009
Nobuto Shibata md
This study indexed the mental status in six living donor liver transplantations (LDLT) performed at the Juntendo University Hospital between 2005 and 2007. The donors' preoperative and postoperative psychiatric and psychological status was assessed using the Profile of Mood States (POMS) and the State,Trait Anxiety Inventory (STAI). The present study found that the donors' POMS anger/hostile score decreased significantly following transplantation. In addition, the STAI score suggested that donors had little anxiety or depression following the operation. Although the present study was limited due to the small number of donors, the findings suggest that a successful operation stabilizes donor mentality. The studied donors will be reassessed for their mental and physical condition in the future. [source]


Comparative Effectiveness Research and Evidence-Based Health Policy: Experience from Four Countries

THE MILBANK QUARTERLY, Issue 2 2009
KALIPSO CHALKIDOU
Context: The discussion about improving the efficiency, quality, and long-term sustainability of the U.S. health care system is increasingly focusing on the need to provide better evidence for decision making through comparative effectiveness research (CER). In recent years, several other countries have established agencies to evaluate health technologies and broader management strategies to inform health care policy decisions. This article reviews experiences from Britain, France, Australia, and Germany. Methods: This article draws on the experience of senior technical and administrative staff in setting up and running the CER entities studied. Besides reviewing the agencies' websites, legal framework documents, and informal interviews with key stakeholders, this analysis was informed by a workshop bringing together U.S. and international experts. Findings: This article builds a matrix of features identified from the international models studied that offer insights into near-term decisions about the location, design, and function of a U.S.-based CER entity. While each country has developed a CER capacity unique to its health system, elements such as the inclusiveness of relevant stakeholders, transparency in operation, independence of the central government and other interests, and adaptability to a changing environment are prerequisites for these entities' successful operation. Conclusions: While the CER entities evolved separately and have different responsibilities, they have adopted a set of core structural, technical, and procedural principles, including mechanisms for engaging with stakeholders, governance and oversight arrangements, and explicit methodologies for analyzing evidence, to ensure a high-quality product that is relevant to their system.

Improved model of secondary clarifier in A2/O process

ASIA-PACIFIC JOURNAL OF CHEMICAL ENGINEERING, Issue 4 2009
Ma Longhua
Abstract The complex behavior of the secondary clarifier and its great importance in the successful operation of the activated sludge process (ASP) have made the settling process a major issue for researchers working in the field of mathematical modeling. So, a precise model of the secondary clarifier can describe the actual behavior of a sewage plant better. But in ASM2, the solid/liquid separation in a secondary clarifier, which is highly nonlinear, is not considered. The solid/liquid separation affects not only the biological reaction but also the quality of the effluent. In this paper an improved secondary clarifier model based on a one-dimensional settler model is established in terms of the solid flux concept and a mass balance. Through some given assumptions, a model of A2/O process including secondary clarifier is built, and then simulated. Copyright © 2009 Curtin University of Technology and John Wiley & Sons, Ltd.

Applying circular posterior-hinged craniotomy to malignant cerebral edemas

CLINICAL ANATOMY, Issue 3 2002
H. Traxler
Abstract Malignant brain edemas are often fatal, regardless of whether they are treated conservatively with sedation, blood pressure management, mannitol-therapy, hyperventilation and hypothermia, or non-conservatively with routine trepanation. Unfortunately, temporal trepanation may result in significant brain damage through herniation of the cerebrum at the edges of the trepanation openings. In one case of a 26-year-old male with severe head injury, a circular posterior-hinged craniotomy (CPHC) was performed after an ineffective unitemporal trepanation for evacuation of an acute subdural hematoma. This ultimately successful operation prompted experimental and morphologic investigations on a new surgical procedure for lowering intracranial pressure (ICP). In 12 of 15 human cadavers, an experimentally ICP was lowered by a CPHC with between 9,21 mm of frontal elevation of the calvaria. Using computer simulation, the frontal elevations of the calvaria were "virtually" performed on 3D reconstructions from CT scans of skulls, and the intracranial volume gained was measured with a computer software program. The volume increase of the cranial cavity showed a relatively constant relation to the cranial capacity and was increased by 6.0% (±0.4%) or 78 cm3 with a 10 mm elevation and by 12.4% (±0.7%) or 160 cm3 with a 20 mm elevation. There were no significant differences with skulls of different ages or ethnic origin; however, a significant effect of gender (F = 7.074; P , 0.013) on the gained volume in percent of the cranial capacity for the 20 mm elevation was observed. This difference can be explained by the inverse relationship between volume increase and cranial capacity (r = ,0.507; P , 0.004). Clin. Anat. Month:173,181, 2002. © 2002 Wiley-Liss, Inc. [source]
