Two cases of primary intracranial choriocarcinoma are reported. One patient died with raised intracranial pressure and pulmonary metastases whereas the second patient, who was diagnosed early, has remained well a year after chemotherapy. Human chorionic gonadotrophin level estimation in serum and cerebrospinal fluid is a useful marker in suspected cases, and chemotherapy following biopsy appear...

this paper presents a new observer design methodology for a time varying actuator fault estimation. a new linear matrix inequality (lmi) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (fafe). the fafe is capable of estimating a wide range of time-varying actuator fault...

Introduction: This study aimed to establish the conversion factors to normalize the output dose of volumetric computed tomography dose index (CTDIvol) to the patient dose (i.e. size-specific dose estimate (SSDE)) for various phantom diameters and tube voltages. Material and Methods: In-house cylindrical acrylic phantoms with physical diameter...

This paper discusses a kernel ridge regression (KRR) model for motion estimation in radiotherapy. Using KRR, dense internal motion fields are estimated from high-dimensional surrogates without the need for prior dimensionality reduction. We compare the proposed model to a related approach with dimensionality reduction in the form of principal component analysis and principle component regressio...

MRI-scanners enable non-invasive, in vivo quantitation of metabolites in, e.g., the brain of a patient. Among other things, this requires adequate estimation of the unknown temporal decay function of the complex-valued signal emanating from the metabolites. We propose a method to render a current decay estimator more simple, accurate, and robust, and test it on a simulated signal comprising con...

OBJECTIVE To examine predictors of blood glucose (BG) estimation accuracy and errors in adolescents with Type 1 diabetes. METHOD Seventy-eight adolescents (ages 11-19) rated their physical symptoms and estimated their BG prior to conducting daily BG tests. BG estimation data were subject to an error grid analysis. Hierarchical regression was used to identify predictors of BG estimation accura...

the first description of an autoimmune encephalitis dates back to 1888, when hermann oppenheim described a patient with neurological symptoms but no underlying brain pathology. the field of autoimmune encephalitides associated with antibodies targeting cell-surface antigens is rapidly expanding and new antibodies are discovered frequently. autoimmune encephalitis is a difficult clinical diagnos...

ae is a serious medical condition in which the immune system attacks the brain, impairing function. with rapid diagnosis and appropriate treatment, many patients recover most or all functions. however, not all patients experience full recovery; with approximately 6% mortality and other patients who never regain significant brain and/or bodily functions. autoimmune encephalitis can produce a wid...

conclusion generally, the studied hospitals were faced with a lack of nursing manpower and distribution of manpower was not appropriate. proper planning and management of manpower in accordance with the lack of personnel, compensates and achieves the standards required for hospital’s nursing manpower and this would lead to an increase in the efficiency of hospitals activities and can provide sa...

introduction: adherence to diet and fluids is the cornerstone of patients undergoing hemodialysis. by informing hemodialysis patients we can help them have a proper diet and reduce mortality and complications of toxins. face to face education is one of the most common methods of training in health care system. but advantages of video- based education are being simple and cost-effective, althoug...
