Acid-base disorders may complicate the presentation of patients with poisoning. This article summarizes an approach to acid-base disorders from a toxicologic perspective. It aims to assist the reader in identifying underlying acid-base processes, generating a differential diagnosis for each, and approaching that differential diagnosis in a systematic fashion. Understanding these processes will help to guide management and interventional strategies. © 2014 Elsevier Inc.

Stroke | Year: 2013

BACKGROUND AND PURPOSE - : In-hospital stroke (IHS) differs from out-of-hospital stroke (OHS) in risk factors and outcomes. We compared IHS and OHS treated with thrombolysis from a large national cohort in a cross-sectional study to further clarify these differences. METHODS - : The Nationwide Inpatient Sample for the years 2005-2010 was searched for adult acute ischemic stroke cases treated with intravenous or intra-Arterial thrombolysis. Patients treated on the day of admission were classified as OHS. We compared the demographic and hospital characteristics, comorbidities, and short-term outcomes of thrombolysed IHS and OHS. RESULTS - : IHS included 8.7% of 11 750 thrombolysed stroke cases in this study. IHS was associated with a higher comorbidity profile and higher rates of acute medical conditions compared with OHS. IHS had higher inpatient mortality (15.7% versus 9.6%; P<0.001) and lower rate of discharge to home/self-care (22.8% versus 30.0%; P<0.001). IHS was also associated with higher mortality among endovascular treatment group (19.3% versus 13.8%; P=0.010). The difference in the rate of all intracerebral hemorrhage was not significant (5.3% versus 4.7%; P=0.361). In the multivariate analysis, inpatient mortality (adjusted odds ratio, 1.59; 95% confidence interval, 1.32-1.92; P<0.001) and favorable discharge outcome (adjusted odds ratio, 0.79; 95% confidence interval, 0.67-0.93; P=0.005) remained significantly worse in IHS. CONCLUSIONS - : Thrombolysed IHS is associated with worse discharge outcomes compared with thrombolysed OHS, likely because of their higher comorbidities and additional medical reasons for the index admission. Thrombolysis is not associated with a higher rate of intracerebral hemorrhage among IHS. © 2013 American Heart Association, Inc.

Objective: We aimed to compare the rates of thrombolysis utilization for acute ischemic stroke in hospitals with neurology residency (NR) to those of other teaching (OT) and nonteaching (NT) hospitals. Methods: A retrospective serial cross-sectional cohort study of a nationally representative sample of stroke patients was conducted. Accreditation Council for Graduate Medical Education- accredited NR program-affiliated hospitals in the United States were cross-matched to the hospitals in the Nationwide Inpatient Sample from 2000 to 2010. ICD-9-CM codes were used for case ascertainment. Results: A total of 712,433 adult ischemic stroke patients from 6,839 hospital samples were included, of whom 10.1%, 29.1%, and 60.8% were treated in NR, OT, and NT hospitals, respectively. Stroke patients in NR received thrombolysis more frequently (3.74% ± 0.24% [standarderror]) than in OT (2.28% ± 0.11%, p < 0.001) and NT hospitals (1.44% ± 0.06%, p < 0.001). The adjusted odds ratios (ORs) of thrombolysis rates in NR vs OT and NR vs NT increased with each decade increment in age. In multivariate analysis, NR was independently predictive of higher thrombolysis rate (adjusted OR 1.51; 95% confidence interval [CI] 1.44-1.59 [NR vs OT], and adjusted OR 1.82; 95% CI 1.73-1.91 [NR vs NT]). Conclusions: Acute stroke care in NR hospitals is associated with an increased thrombolytic utilization. The disparities between the thrombolysis rate in NR and that in OT and NT hospitals are greater among elderly patients. © 2013 American Academy of Neurology. © 2013 American Academy of Neurology.

Cholangiocarcinoma (CCA) is an aggressive malignancy that originates from the epithelial cells of the biliary duct system. Depending on the anatomical location, CCA can be considered extrahepatic (eCCA) or intrahepatic (iCCA) (1). Two thirds of CCAs involve the extrahepatic biliary system, whereas the rest are confined within the liver parenchyma, beyond the secondary biliary radicals (2). Due to its biological aggressiveness and difficulty in diagnosis, the majority of patients with CCA are unresectable at presentation and the overall 5-year survival is approximately five percent (4). This article focuses on the genetic and epigenetic alterations present in cholangiocarcinomas, their occasional relationship to external stimuli, and with an emphasis on those unanswered questions about cholangiocarcinogenesis and future directions in the comprehension of epigenetic DNA methylation in patients with CCA. © 2016 Elsevier Inc.

Thrombolysis with alteplase administered within a narrow therapeutic window provides an effective therapy for acute ischaemic stroke. However, mainly because of prehospital delay, patients often arrive too late for treatment, and no more than 1-8% of patients with stroke obtain this treatment. We recommend that all links in the prehospital stroke rescue chain must be optimised so that in the future more than a small minority of patients can profit from time-sensitive acute stroke therapy. Measures for improvement include continuous public awareness campaigns, education of emergency medical service personnel, the use of standardised, validated scales for recognition of stroke symptoms and for triaging to the appropriate institution, and advance notification to the receiving hospital. In the future, use of telemedicine technologies for interaction between the emergency site and hospital, and the strategy of treatment directly at the emergency site (mobile stroke unit concept), could contribute to more efficient use of resources and reduce the time taken to instigate treatment to within 60 min-the golden hour-of the onset of the symptoms of stroke. © 2013 Elsevier Ltd.

Complications from uncontrolled diabetes mellitus were reduced significantly with the introduction of insulin more than 90 years ago. Despite the proven benefits of normal glycemic levels, patients are deterred by the inconvenience and perceived pain related to multiple daily subcutaneous insulin injections. Inhaled insulin was first approved by the U.S. Food and Drug Administration (FDA) in 2006, but because profit margins did not achieve expectations, the drug manufacturer discontinued sales 2 years later. The second-generation inhaled insulin, developed with Technosphere technology, received FDA approval in 2014. The pharmacology, pharmacokinetics, drug interactions, clinical safety and efficacy, patient satisfaction, dosage and administration, warnings, precautions, contraindications, adverse effects, and place in therapy of inhaled Technosphere insulin are reviewed in this article. © 2015 Pharmacotherapy Publications, Inc.

Background and Purpose-Purpose in life, the sense that life has meaning and direction, is associated with reduced risks of adverse health outcomes. However, it remains unknown whether purpose in life protects against the risk of cerebral infarcts among community-dwelling older people. We tested the hypothesis that greater purpose in life is associated with lower risk of cerebral infarcts. Methods-Participants came from the Rush Memory and Aging Project. Each participant completed a standard measure of purpose in life. Uniform neuropathologic examination identified macroscopic infarcts and microinfarcts, blinded to clinical information. Association of purpose in life with cerebral infarcts was examined in ordinal logistic regression models using a semiquantitative outcome. Results-Four hundred fifty-three participants were included in the analyses. The mean score on the measure of purpose was 3.5 (SD, 0.5; range, 2.1-5.0). Macroscopic infarcts were found in 154 (34.0%) people, and microinfarcts were found in 128 (28.3%) people. Greater purpose in life was associated with a lower odds of having more macroscopic infarcts (odds ratio, 0.535; 95% confidence interval, 0.346-0.826; P=0.005), but we did not find association with microinfarcts (odds ratio, 0.780; 95% confidence interval, 0.495-1.229; P=0.283). These results persisted after adjusting for vascular risk factors of body mass index, history of smoking, diabetes mellitus, and blood pressure, as well as measures of negative affect, physical activity, and clinical stroke. The association with macroscopic infarcts was driven by lacunar infarcts, and was independent of cerebral atherosclerosis and arteriolosclerosis. Conclusions-Purpose in life may affect risk for cerebral infarcts, specifically macroscopic lacunar infarcts. © 2015 American Heart Association, Inc.

Blood transfusions have become indispensable to treat the anemia associated with a variety of medical conditions ranging from genetic disorders and cancer to extensive surgical procedures. In developed countries, the blood supply is generally adequate. However, the projected decline in blood donor availability due to population ageing and the difficulty in finding rare blood types for alloimmunized patients indicate a need for alternative red blood cell (RBC) transfusion products. Increasing knowledge of processes that govern erythropoiesis has been translated into efficient procedures to produce RBC ex vivo using primary hematopoietic stem cells, embryonic stem cells, or induced pluripotent stem cells. Although in vitro-generated RBCs have recently entered clinical evaluation, several issues related to ex vivo RBC production are still under intense scrutiny: among those are the identification of stem cell sources more suitable for ex vivo RBC generation, the translation of RBC culture methods into clinical grade production processes, and the development of protocols to achieve maximal RBC quality, quantity, and maturation. Data on size, hemoglobin, and blood group antigen expression and phosphoproteomic profiling obtained on erythroid cells expanded ex vivo from a limited number of donors are presented as examples of the type of measurements that should be performed as part of the quality control to assess the suitability of these cells for transfusion. New technologies for ex vivo erythroid cell generation will hopefully provide alternative transfusion products to meet present and future clinical requirements. © AlphaMed Press.

Human immunodeficiency virus (HIV) infection has progressed to a chronic disease and HIV positive individuals are living longer lives. This has lead to an increase in morbidity and mortality due to secondary issues, one being HIV bone disease. HIV infected pediatric and adult populations have a greater incidence in reduction of BMD as compared to the controls. Osteoporosis has been reported to be present in up to 15 % of HIV positive patients. We are starting to understand the mechanism behind the changes in HIV bone disease. Viral proteins interfere with osteoblastic activity either by direct interaction or by the inflammatory process that they induce. Anti-viral management, including highly active antiretroviral therapy (HAART), protease inhibitors, and nucleoside/nucleotide reverse transcriptase inhibitors (NRTI) also are involved in disrupting proper bone metabolism. Vitamin D levels have strong correlation with bone disease in HIV patients, and are dependent not only to chronic disease state, but interaction of pharmacologic management and inflammatory process as well. Work up of the secondary causes of osteopenia and osteoporosis should be undertaken in all patients. DEXA scan is recommended in all post-menopausal women with HIV, all HIV infected men 50 years of age or older and in those with a history of fragility fractures regardless of age or gender. Preventive measures include adequate nutrition, calcium and Vitamin D intake daily, muscle strengthening and balance exercises to increase BMD and reduce fractures. Bisphosphonates are considered to be the first line for the treatment of HIV associated bone disease. This review will describe how the balanced mechanism of bone metabolism is interrupted by the HIV infection itself, the complications that arise from HIV/AIDS, and its treatment options. © 2013 Springer Science+Business Media New York.

Electroencephalography (EEG) can help narrow the differential diagnosis of altered mental status (AMS) and is necessary to diagnose nonconvulsive seizure (NCS). The objective of this prospective observational study is to identify the prevalence of EEG abnormalities in emergency department patients with AMS. Patients of at least 13 years of age with AMS were enrolled, whereas those with an easily identifiable cause (e.g. hypoglycemia) underlying their AMS were excluded. Easily identifiable cause of AMS (e.g. hypoglycemia). A 30-min EEG with the standard 19 electrodes was performed on each patient. Descriptive statistics (%, 95% confidence interval) are used to report EEG findings of the first 50 enrolled patients. Thirty-five EEGs (70%, 57-81%) were abnormal. The most common abnormality was slowing of background activities (46%, 33-60%), reflecting an underlying encephalopathy. NCS was diagnosed in three (6%, 1-17%), including one patient in nonconvulsive status epilepticus. Nine patients (18%, 10-31%) had interictal epileptiform abnormalities, indicating an increased risk of spontaneous seizure. Patients presenting to the emergency department with AMS have a high prevalence of EEG abnormalities, including NCS. © 2013 Wolters Kluwer Health | Lippincott Williams &Wilkins.
