METHODS: All consecutive inpatients with a duplex scan diagnosis of isolat...

The administration of injections is a fundamental nursing skill; however, it is not without risk. Children receive numerous vaccines, and pediatric nurses administer the majority of these vaccines via the intramuscular route, and thus must be knowledgeable about safe and evidence-based immunization programs. Nurses may not be aware of the potential consequences associated with poor injection pract...

In 328 immunocompromised patients, 105 with and 193 without Pneumocystis jiroveci pneumonia (PCP), serum lactate dehydrogenase (LDH) was analysed retrospectively, taking into consideration the time interval from the onset of symptoms to the start of specific therapy. 97 of the 105 PCP patients were negative for human immunodeficiency virus (HIV). Eight were positive. Of the 193 patients without PC...

Traditional teaching has held that horizontal-gaze nystagmus is a sign of intoxication by sedatives such as alcohol but not marijuana. This is a case report of an adult male who presents with 3 days of visual disturbance and dizziness following marijuana use. The exam was notable for gaze-evoked nystagmus and ataxia. Lab testing was normal except that urine drug screening was positive for marijuan...

Tourette's syndrome in adults.

Added: 06:00 EDT 7 Aug 2010

Tourette's syndrome (TS) is defined as motor and phonic tics starting before age 18 years, and therefore most studies have focused on childhood TS, whereas the disorder in adults has not been well characterized. We reviewed medical records of all new TS patients referred to our Movement Disorders Clinic over the past 5 years, 19 years or older on initial evaluation and compared them with 100 TS pa...

INTRODUCTION. Because Alzheimer's disease (AD) needs to be treated as soon as possible after onset, its early detection has become one of the core areas of research in the field of neurodegenerative diseases. DEVELOPMENT. Attempts to characterise the incipient phases of the disease have evolved from the appearance of the heterogeneous concept of mild cognitive impairment in the last twentieth cent...

Professional values and nursing.

Added: 06:00 EST 10 Nov 2010

The values of nursing arise from a concern with human flourishing. If the desire to become a nurse is a reflection of an aspiration to care for others in need then we should anticipate that those who choose to nurse have a tendency towards the values we would normally associate with a caring profession (care, compassion, perhaps altruism, and so on). However, these values require a secure base if ...

ABSTRACTBackground: The aim of the study was to investigate whether urinary tract infection (UTI) in a representative sample of 85-, 90- and >/=95-year-old women is associated with delirium.Methods: In 504 out of 643 women (78.4%) it was possible to evaluate UTI and delirium. Assessments such as the Organic Brain Syndrome (OBS) Scale, the Geriatric Depression Scale-15 (GDS-15) and the Mini-mental ...

Parkinson's disease (PD) is a degenerative, chronic and irreversible condition. Palliative medicine may play an important role in the care of patients with PD to maintain the quality of life. Scopolamine is a non-competitive antagonist at muscarinic acetylcholine receptors, which was used many years ago in the treatment for PD. To the best of our knowledge, there are no previously reported cases o...

Shortness of breath is a common complaint in those with chronic liver disease. The differential diagnosis for this complaint includes primary pulmonary disorders, systemic disorders that affect the liver and lungs, and extrahepatic manifestations of portal hypertension. Orthotopic liver transplant, when appropriate, is the most effective therapy for many patients with dyspnea and chronic liver dis...

Abstract Background. Lumbar spinal stenosis is a common condition that causes axial low back pain, radicular pain, and neurogenic claudication. Epidural steroid injections are commonly used for the treatment of radicular symptoms and neurogenic claudication associated with symptomatic lumbar spinal stenosis. No prior study has evaluated whether transforaminal or interlaminar epidural steroid injec...

Thrombocytopenia is usually acquired. The laboratory artefact of pseudothrombocytopenia should always be excluded. Bone marrow insufficiency with impaired platelet production results from infiltrating tumor cells or from a myelodsplastic syndrome. In patients with splenomegaly, platelets are trapped by the spleen. An increased platelet turnover is caused by activation of the clotting cascade, e.g....

Bereavement is a severe stressor that typically incites painful and debilitating symptoms of acute grief that commonly progresses to restoration of a satisfactory, if changed, life. Normally, grief does not need clinical intervention. However, sometimes acute grief can gain a foothold and become a chronic debilitating condition called complicated grief. Moreover, the stress caused by bereavement, ...

There were 42 patients in this study, and they ...

What is Intrinsic Atopic Dermatitis?

Added: 06:00 EDT 25 May 2011

Many authors favor a distinction between the extrinsic and intrinsic forms of atopic dermatitis. In this review, the controversy is discussed and several definitions are presented. After reviewing many papers on this topic, it is our opinion that it is useful to separate the intrinsic and extrinsic forms of atopic dermatitis or atopic eczema and atopiform dermatitis because the pathophysiology app...

Diuretics are agents commonly used in diseases characterized by excess extracellular fluid, including chronic kidney disease, the nephrotic syndrome, cirrhosis and heart failure. Multiple diuretic classes, including thiazide-type diuretics, loop diuretics and K(+)-sparing diuretics, are used to treat patients with these diseases, either individually or as combination therapies. An understanding of...

Desmopressin acetate (DDAVP), a medication used in the treatment of bleeding and polyuric disorders, has the potential to cause hyponatremia when free water is not appropriately restricted with its use. This free water retention is reversible when DDAVP is discontinued. We report a case of symptomatic DDAVP-induced hyponatremia in which discontinuation of DDAVP led to a rapid increase of serum sod...

We conducted an epidemiologic survey in France on the use of bicaval dual-lumen cannulas for extracorporeal membrane oxygenation (ECMO). Every service that used the Avalon cannula was contacted. Practitioners answered questions concerning its practical usage and complications that were attributable to its usage. We report data for 52 instances of cannula usage. The primary indication was acute res...

METHODS: This is a retrospective review of all patients with positive anti-dsDNA assay (more than 200 IU/ml) tested for any underlying etiology from January to December 2007 at King Abdu...

BACKGROUND:: Cerebrospinal fluid (CSF) protein values decline over the first few months of life as the infant's blood-CSF barrier matures. However, published studies differ in the reported rate, timing, and magnitude of this decline. OBJECTIVE:: To quantify the age-related changes in CSF protein concentration and to determine accurate, age-specific reference values for neonates and young infants. ...

Gastric-type epithelium and islands of oxyntic mucosa in duodenal biopsies are considered by some to be part of a spectrum of metaplastic change related to peptic disorders. This study was designed to assess prevalence and associations of metaplastic-heterotopic gastric mucosa in the duodenum. Demographic, clinical, and histopathologic data from patients who had duodenal biopsy specimens for a 12-...

Background and Aims: Equation for Japanese estimated glomerular filtration rate (eGFR) has been revised by measuring GFR using inulin clearance. We assessed in an elderly Japanese population the association of the new eGFR with all-cause mortality and mortality from cardiovascular disease (CVD). Methods: Seventy-year-old subjects who resided in Niigata city, Japan participated. Baseline examinatio...

Background D-dimers are used in conjunction with clinical probability scores in the assessment of venous thromboembolism (VTE), and they are elevated in other conditions, including malignancy, infection and arrhythmias. High levels of D-dimers in VTE are associated with adverse outcomes, including increased mortality. Their significance in patients without VTE has not previously been established. ...

While uncommon, isolated avulsion fractures of the lesser trochanter occur in children and adolescents prior to the fusion of this apophysis as a result of athletic activities. In the elderly, isolated fractures of the lesser trochanter are rare but can occur as a result of trauma. They have been identified in patients with primary or secondary bone malignancies, which were previously considered p...

Current treatment for type II endoleak includes transarterial embolization and translumbar puncture, but each method has its drawbacks. With real-time three-dimensional fluoroscopy guidance, a cone-beam computed tomography (CT) image is created in which the needle trajectory is determined. The trajectory is superimposed on the fluoroscopy image, allowing real-time needle placement for precise embo...

VOICE DISORDERS IN ASTHMABronchial asthma is one of the most common chronic diseases with a prevalence of 5% in Germany. Nearly half of the patients complain about permanent voice disorders. Mucosal changes due to the obstructive respiratory disease as well as mucus abnormalities and regularly accompanying chronic rhinosinusitis may explain these symptoms. The additional influence of laryngopharyn...

About half of the patients suffering from heart failure present with sleep-disordered breathing. In most cases obstructive and central breathing disturbances (including Cheyne-Stokes respiration [CSR]) coexist. CSR is defined by a waxing and waning pattern of the tidal volume. While its pathophysiology has not been elucidated completely, increased ventilatory sensitivity for CO2 and therefore an i...

BACKGROUND: Hip fractures in the elderly are associated with high 1-year mortality rates, but whether patients with other lower extremity fractures are exposed to a similar mortality risk is not clear. QUESTIONS/PURPOSES: We evaluated the mortality of elderly patients after distal femur fractures; determined predictors for mortality; analyzed the effect of surgical delay; and compared survivorship...

BACKGROUND: Medical management of cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH) includes hypertensive, hypervolemic, and hemodilution ("triple-H") therapy. However, there is little information regarding the indications and guidance used to initiate and adjust triple-H therapy. METHODS: A 43-item questionnaire was e-mailed to 375 members of the Neurocritical Care Society. Qu...

Anesthesia for the Patient with Dementia.

Added: 06:00 EDT 23 Sep 2010

With a growing aging population, more patients suffering from dementia are expected to undergo surgery, thus being exposed to either general or regional anesthesia. This calls for specific attention ranging from the legal aspects of obtaining informed consent in demented patients to deciding on the use of premedication, choice of anesthetics, and management of postoperative pain. This review refle...

Background: It is believed that patients who undergo thyroidectomy for Graves' disease are more likely to experience postoperative hypocalcemia than patients undergoing total thyroidectomy for other indications. However, no study has directly compared these two groups of patients. The aim of this study was to determine whether there was an increased incidence or severity of postoperative hypocalce...

Background & aims: The use of low-molecular-weight heparins (LMWH) in patients with advanced liver diseases is frequently avoided because of the enhanced risk of bleeding complications. However, many patients with impaired liver function are at a high risk of thrombosis or have an indication for therapeutic anticoagulation. Therefore, the aim of this study was to evaluate the pharmacokinetics of L...

For many years glucocorticoids have been used world-wide in pregnant women for treatment of a variety of medical disorders, from bronchial asthma to systemic lupus erythematosous, to renal transplant. More recently their administration has been successfully addressed to the prevention of congenital fetal diseases. In some of these, such as for instance the 21-hydroxylase deficiency leading to cong...

The rendezvous procedure combines an endoscopic technique with percutaneous transhepatic biliary drainage (PTBD). When a selective common bile duct cannulation fails, PTBD allows successful drainage and retrograde access for subsequent rendezvous techniques. Traditionally, rendezvous procedures such as the PTBD-assisted over-the-wire cannulation method, or the parallel cannulation technique, may b...

WHO grading of human brain tumors extends beyond a strictly histological grading system by providing a basis predictive for the clinical behavior of the respective neoplasm. For example, patients with glioblastoma WHO grade IV usually show a less favorable clinical course and receive more aggressive first-line treatment than patients with anaplastic astrocytoma WHO grade III. Here we provide evide...

The leak rates of different gastrointestinal anastomoses vary considerably but despite this there are common and general concepts for diagnosis and management. Early diagnosis and timely consistent therapy must guide management to prevent harm to the patients. Diagnosis of anastomotic leaks is coupled to clinical signs of the patients and should be initiated promptly. Dependent on the localization...

Acute respiratory distress syndrome (ARDS) is a common and severe form of acute lung injury, resulting from both direct (eg, pneumonia) and indirect (eg, sepsis) pulmonary insults. It is a common cause of admission to the intensive care unit due to hypoxemic respiratory failure requiring mechanical ventilation, and is associated with significant morbidity and mortality. In some patients, ARDS lead...

A high anion gap in diabetic ketoacidosis (DKA) suggests that some unmeasured anions must contribute to the generation of the anion gap. We investigated the contribution of D-lactate to the anion gap in DKA.

Traumatic brain injury (TBI) results in a variable degree of cerebral atrophy that is not always related to cognitive measures across studies. However, the use of different methods for examining atrophy may be a reason why differences exist. The purpose of this manuscript was to examine the predictive utility of seven magnetic resonance imaging (MRI) -derived brain volume or indices of atrophy for...

A 60-year-old woman with advanced Huntington's disease and a recent episode of aspiration pneumonia presented with erythema, edema, and blistering of the right forearm. An 18-gauge peripheral intravenous catheter had been partially displaced from the same site 10 hours earlier, resulting in infusion of an unknown quantity of parenteral-nutrition solution (80 g of dextrose per liter, 22 g of amino ...

OPINION STATEMENT: Dolichoectasia is a dilatation and elongation of the arteries, usually affecting intracranial basilar and vertebral arteries. It may cause posterior circulation stroke or transient ischemic attacks independent of atherosclerotic disease. Compression of cranial nerves or brainstem leads to hemifacial spasm, trigeminal neuralgia, or brainstem dysfunction (temporary or permanent). ...

INTRODUCTION: Autologous bone graft is still considered to be the gold standard for treating non-unions in trauma and orthopedic surgery. Intramedullary bone graft harvest appears to be an alternative to other bone graft options such as iliac crest bone graft and synthetic bone substitutes. A one-step reamer-irrigator-aspirator (RIA) system has been developed to reduce the intramedullary pressure ...
