    Disposition of [H] Phencyclidine in brain, plasma and adipose tissue of rats acutely and chronically-treated with ethanol was studied using a method possessing high sensitivity and specificity for PCP. In rats acutely-treated with ethanol (5 g/kg PO dose) and PCP (10 mg/kg IP dose), dispositional factors did not play a role in the intensifies pharmacological and behavioral effects of PCP. However in rats chronically-treated with 2.5 g/kg PO dose of ethanol twice a day for 19 days, the disposition of PCP (5 mg/kg IP dose) was significantly altered and the values of PCP in brain, plasma and adipose tissue were significantly higher than those in the control group. Although inhibition of PCP metabolism and a comparatively slower rate of its elimination appear to account for the potentiation of drug effects in animals chronically-treated with ethanol, interaction of drugs at the level of the central nervous system cannot be ruled out.

    This article presents the proceedings of a symposium entitled "The Tipsy Terminal: Presynaptic Effects of Ethanol" (held at the annual meeting of the Research Society on Alcoholism, in Santa Barbara, CA, June 27, 2005). The objective of this symposium was to focus on a cellular site of ethanol action underrepresented in the alcohol literature, but quickly becoming a "hot" topic. The chairs of the session were Marisa Roberto and George Robert Siggins. Our speakers were chosen on the basis of the diverse electrophysiological and other methods used to discern the effects of acute and chronic ethanol on presynaptic terminals and on the basis of significant insights that their data provide for understanding ethanol actions on neurons in general, as mechanisms underlying problematic behavioral effects of alcohol. The 5 presenters drew from their recent studies examining the effects of acute and chronic ethanol using a range of sophisticated methods from electrophysiological analysis of paired-pulse facilitation and spontaneous and miniature synaptic currents (Drs. Weiner, Valenzuela, Zhu, and Morrisett), to direct recording of ion channel activity and peptide release from acutely isolated synaptic terminals (Dr. Treistman), to direct microscopic observation of vesicular release (Dr. Morrisett). They showed that ethanol administration could both increase and decrease the probability of release of different transmitters from synaptic terminals. The effects of ethanol on synaptic terminals could often be correlated with important behavioral or developmental actions of alcohol. These and other novel findings suggest that future analyses of synaptic effects of ethanol should attempt to ascertain, in multiple brain regions, the role of presynaptic terminals, relevant presynaptic receptors and signal transduction linkages, exocytotic mechanisms, and their involvement in alcohol's behavioral actions. Such studies could lead to new treatment strategies for alcohol intoxication

    Ethanol is an effective ablative agent used for the treatment of certain solid organ tumors and vascular malformations (VMs). The egress of ethanol beyond the target tissue can be associated with significant changes to the cardiopulmonary system that can lead to cardiac arrest. This article reviews the contemporary role of ethanol in tumor and VM treatment and discusses the physiological mechanisms of acute pulmonary hypertension and cardiovascular collapse. The importance of periprocedural recognition of the hemodynamic changes that can occur with the use of ethanol and the treatment of this condition are discussed.

    Full Text Available There is no specific treatment for acute pancreatitis. Majority of patients with acute pancreatitis respond to medical therapy. Supportive measures and close observations represent the cornerstone of the medical therapy. Failure to respond to medical treatment may indicate choledocholithiasis or infected necrosis. Endoscopic papillotomy with stone retrieval is beneficial in patients with severe biliary pancreatitis. Image-guided fine needle aspiration and bacteriological examination of aspirate is reliable in detecting infection and deliniating causative pathogen. Surgical debridement is the method of choice for treatment of infected necrosis. In contrast, in pancreatic abscess, surgery is preserved for those, who do not respond to percutaneous drainage combined with antibiotics. The benefit of antisecretory and antiproteolytic agents is debatable. A combination of antioxidants, calcium channel antagonists and antibiotics may play a major role in the treatment of acute pancreatitis in the future.

    Full Text Available Objective: The objective was to evaluate the acute effect of melatonin on ethanol drinking in ethanol naïve rats and to determine the specificity of the effect of melatonin on ethanol intake as compared to an intake of plain tap water or sugar water. Materials and Methods: A total of three experiments (2 weeks duration each using different drinking solutions (ethanol, plain tap water, sugar water was conducted in individually housed male wistar rats of 5 weeks age. Each animal had access to bottles containing drinking solutions for 2 h a day. In each experiment, on day 1, day 2, day 4, day 5, day 8, day 9, day 11, day 12 rats received drinking solutions. Each individual rat received single doses of saline, melatonin (50 mg and 100 mg/kg, and naltrexone on day 2, 5, 9, and 12, 1-h before receiving drinking solution. The order of drug administration is permuted such a way that each animal received the drugs in a different order in different experiments. Results: Melatonin has significantly decreased ethanol consumption by the rats and effect is dose-dependent. Naltrexone also has caused a significant reduction in the ethanol consumption. The maximum reduction in ethanol consumption was seen with melatonin 100 mg/kg dose compared to melatonin 50 mg/kg and naltrexone. There was no statistically significant effect of melatonin on plain water and sugar solution intake. Conclusions : Melatonin decreases ethanol consumption in ethanol naïve rats. The effect of melatonin is similar to naltrexone affecting selectively ethanol consumption, but not plain water and sugar water consumption.

    Background/Aims An increase of ethanol metabolism and hepatic mitochondrial respiration occurs in vivo after a single binge of alcohol. Here, our aim was to determine how ethanol intake affects hepatic mitochondrial polarization status in vivo in relation to ethanol metabolism and steatosis. Methods Hepatic mitochondrial polarization, permeability transition (MPT), and reduce pyridine nucleotides, and steatosis in mice were monitored by intravital confocal/multiphoton microscopy of the fluorescence of rhodamine 123 (Rh123), calcein, NAD(P)H, and BODIPY493/503, respectively, after gavage with ethanol (1–6 g/kg). Results Mitochondria depolarized in an all-or-nothing fashion in individual hepatocytes as early as 1 h after alcohol. Depolarization was dose- and time-dependent, peaked after 6 to 12 h and maximally affected 94% of hepatocytes. This mitochondrial depolarization was not due to onset of the MPT. After 24 h, mitochondria of most hepatocytes recovered normal polarization and were indistinguishable from untreated after 7 days. Cell death monitored by propidium iodide staining, histology and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) was low throughout. After alcohol, mitochondrial NAD(P)H autofluorescence increased and decreased, respectively, in hepatocytes with polarized and depolarized mitochondria. Ethanol also caused steatosis mainly in hepatocytes with depolarized mitochondria. Depolarization was linked to ethanol metabolism, since deficiency of alcohol dehydrogenase and cytochrome-P450 2E1 (CYP2E1), the major ethanol-metabolizing enzymes, decreased mitochondrial depolarization by ∼70% and ∼20%, respectively. Activation of aldehyde dehydrogenase decreased depolarization, whereas inhibition of aldehyde dehydrogenase enhanced depolarization. Activation of aldehyde dehydrogenase also markedly decreased steatosis. Conclusions Acute ethanol causes reversible hepatic mitochondrial depolarization in vivo that may contribute to

    Twelve male Sprague-Dawley rats were trained in a standard two-choice Drug 1-Drug 2 discrimination task utilizing 3.0 mg/kg chlordiazepoxide (CDP, an anxiolytic drug) and 20 mg/kg pentylenetetrazol (PTZ, an anxiogenic drug) as discriminative stimuli under a VR 5-15 schedule of food reinforcement. Saline tests conducted at specific time points after acute high doses of ethanol (3.0 and 4.0 g/kg) indicated a delayed rebound effect, evidenced by a shift to PTZ-appropriate responding. Insofar as such a shift in lever selection indexes a delayed anxiety-like state, this acute 'withdrawal' reaction can be said to induce an affective state similar to that seen with chronic ethanol withdrawal states. Ethanol generalization tests: (1) resulted in a dose- and time-dependent biphasic generalization to CDP, (2) failed to block the PTZ stimulus and (3) failed to block the time- and dose-dependent elicitation of an ethanol-rebound effect. These data suggest that ethanol's anxiolytic effects are tenuous. PMID:2791886

    The present study aimed to evaluate the effect of an oral administration of marine collagen peptides (MCPs) pre- and post-acute ethanol intoxication in female Sprague-Dawley (SD) rats. MCPs were orally administered to rats at doses of 0 g per kg bw, 2.25 g per kg bw, 4.5 g per kg bw and 9.0 g per kg bw, prior to or after the oral administration of ethanol. Thirty minutes after ethanol treatment, the effect of MCPs on motor incoordination and hypnosis induced by ethanol were investigated using a screen test, fixed speed rotarod test (5 g per kg bw ethanol) and loss of righting reflex (7 g per kg bw ethanol). In addition, the blood ethanol concentrations at 30, 60, 90, and 120 minutes after ethanol administration (5 g per kg bw ethanol) were measured. The results of the screen test and fixed speed rotarod test suggested that treatment with MCPs at 4.5 g per kg bw and 9.0 g per kg bw prior to ethanol could attenuate ethanol-induced loss of motor coordination. Moreover, MCP administered both pre- and post-ethanol treatment had significant potency to alleviate the acute ethanol induced hypnotic states in the loss of righting reflex test. At 30, 60, 90 and 120 minutes after ethanol ingestion at 5 g per kg bw, the blood ethanol concentration (BEC) of control rats significantly increased compared with that in the 4.5 g per kg bw and 9.0 g per kg bw MCP pre-treated groups. However, post-treatment with MCPs did not exert a significant inhibitory effect on the BEC of the post-treated groups until 120 minutes after ethanol administration. Therefore, the anti-inebriation effect of MCPs was verified in SD rats with the possible mechanisms related to inhibiting ethanol absorption and facilitating ethanol metabolism. Moreover, the efficiency was better when MCPs were administered prior to ethanol.

    Full Text Available Objectives: Alcohol abuse is a public issue and one of the major causes of liver disease worldwide. This study was aimed at investigating the protective effect of Ganoderma lucidum pharmacopuncture (GLP against hepatotoxicity induced by acute ethanol (EtOH intoxication in rats. Methods: Sprague-Dawley (SD rats were divided into 4 groups of 8 animals each: normal, control, normal saline pharmacopuncture (NP and GLP groups. The control, NP and GLP groups received ethanol orally. The NP and the GLP groups were treated daily with injections of normal saline and Ganoderma lucidum extract, respectively. The control group received no treatment. The rats in all groups, except the normal group, were intoxicated for 6 hours by oral administration of EtOH (6 g/kg BW. The same volume of distilled water was administered to the rats in the normal group. Two local acupoints were used: Qimen (LR14 and Taechung (LR3. A histopathological analysis was performed, and the liver function and the activities of antioxidant enzymes were assessed. Results: GLP treatment reduced the histological changes due to acute liver injury induced by EtOH and significantly reduced the increase in the alanine aminotransferase (ALT enzyme; however, it had an insignificant effect in reducing the increase in aspartate aminotransferase (AST enzyme. It also significantly ameliorated the superoxide dismutase (SOD and the catalase (CAT activities. Conclusion: The present study suggests that GLP treatment is effective in protecting against ethanol-induced acute hepatic injury in SD rats by modulating the activities of ethanol metabolizing enzymes and by attenuating oxidative stress.

    Ethanol consumption is linked to a higher incidence of traumatic wounds and increases the risk for morbidity and mortality following surgical or traumatic injury. One of the most profound effects of acute ethanol exposure on wound healing occurs during the inflammatory response, and altered cytokine production is a primary component. Acute ethanol exposure also impairs the proliferative response during healing, causing delays in epithelial coverage, collagen synthesis, and blood vessel regrow...

    Full Text Available The anti-inflammatory effect of an ethanol extract of Helicteres gardneriana (Nees Castiglioni was assayed in experimental models of pleurisy and microcirculation in situ. Treatment of animals with 500 mg/kg body weight reduced the exudate volume (35% reduction induced by intrapleural injection of carrageenan and the migration of polymorphonuclear cells into the inflamed pleural cavity of rats (40%. Additionally, rolling and adhesion of leukocytes and the number of leukocytes that migrated toward the perivascular space in response to the carrageenan injection were decreased by the extract (500 mg/kg. These data demonstrate the anti-inflammatory effect of the ethanol extract of Helicteres gardneriana and imply that inhibition of leukocyte-endothelial interactions is important in the extract's mechanism of action.

    Taylor, Frederick R

    2010-04-01

    Optimum acute treatment of migraine requires prevention of headache as a top priority. Recognition of the multitude of migraine presentations, the frequency of total headache attacks, and number of days of headache disability are critical. Successful treatment requires excellent patient-clinician communication enhancing confidence and mutual trust based on patient needs and preferences. Optimum management of acute migraine nearly always requires pharmacologic treatment for rapid resolution. Migraine-specific triptans, dihydroergotamine, and several antiinflammatories have substantial empirical clinical efficacy. Older nonspecific drugs, particularly butalbital and opioids, contribute to medication overuse headache and are to be avoided. Clinicians should utilize evidence-based acute migraine-specific therapy stressing the imperative acute treatment goal of early intervention, but not too often with the correct drug, formulation, and dose. This therapy needs to provide cost-effective fast results, meaningful to the patient while minimizing the need for additional drugs. Migraine-ACT evaluates 2-hour pain freedom with return to normal function, comfort with treatment, and consistency of response. Employ a thoroughly educated patient, formulary, testimonials, stratification, and rational cotherapy against the race to central sensitization for optimum outcomes. PMID:20352584

  20. Drosophila highwire gene modulates acute ethanol sensitivity in the nervous system

    Animals exhibit behavioral differences in their sensitivity to ethanol,a trait that is at least in part due to genetic predispositions.This study has implicated a large neuronal protein involving Highwire,a Drosophila E3 ubiquitin ligase (Hiw,a homolog of Pam,a protein associated with Myc found in humans) in acute sensitivity to ethanol sedation.Flies lacking Hiw were hypersensitive to the sedating effect of ethanol whereas those overexpressing Hiw showed decreased sensitivity to ethanol.Furthermore,RNAi functional knockdown of Hiw in adult neurons or ellipsoid body neurons showed increased sensitivity to ethanol sedation.None of these manipulations of the hiw gene caused changes in the rate of ethanol absorption and/or metabolism.These results suggest a previously unknown role for this highly conserved gene in regulating the behavioral responses to an addictive drug.

    AIM: To investigate the role of metallothionein and proliferating cell nuclear antigen (PCNA) on the morphological and biochemical effects of zinc sulfate in ethanol-induced liver injury.METHODS: Wistar albino rats were divided into four groups. Group I; intact rats, group Ⅱ; control rats given only zinc, group Ⅲ; animals given absolute ethanol, group Ⅳ; rats given zinc and absolute ethanol.Ethanol-induced injury was produced by the 1 mL of absolute ethanol, administrated by gavage technique to each rat. Animals received 100 mg/kg per day zinc sulfate for 3 d 2 h prior to the administration of absolute ethanol.RESULTS: Increases in metallothionein immunoreactivity in control rats given only zinc and rats given zinc and ethanol were observed. PCNA immunohistochemistry showed that the number of PCNA-positive hepatocytes was increased significantly in the livers of rats administered ethanol + zinc sulfate. Acute ethanol exposure caused degenerative morphological changes in the liver. Blood glutathione levels decreased, serum alkaline phosphatase and aspartate transaminase activities increased in the ethanol group when compared to the control group. Liver glutathione levels were reduced, but lipid peroxidation increased in the livers of the group administered ethanol as compared to the other groups. Administration of zinc sulfate in the ethanol group caused a significant decrease in degenerative changes, lipid peroxidation, and alkaline phosphatase and aspartate transaminase activities, but an increase in liver glutathione.CONCLUSION: Zinc sulfate has a protective effect on ethanol-induced liver injury. In addition, cell proliferation may be related to the increase in metallothionein immunoreactivity in the livers of rats administered ethanol + zinc sulfate.

  2. Acute treatment of atrial fibrillation.

    1998-03-12

    Atrial fibrillation (AFib) is a common clinical entity, responsible for significant morbidity and mortality, but it also accounts for a large percentage of healthcare dollar expenditures. Efforts to treat this arrhythmia in the past have focused on subacute antithrombotic therapy and eventually use of antiarrhythmic drugs for maintenance of sinus rhythm. However, there has been a growing interest in the concept of acute electrical and pharmacologic conversion. This treatment strategy has a number of benefits, including immediate alleviation of patient symptoms, avoidance of antithrombotic therapy, and prevention of electrophysiologic remodeling, which is thought to contribute to the perpetuation of the arrhythmia. There is also increasing evidence that this is a cost-effective strategy in that it may obviate admission to the hospital and the cost of long-term therapy. This article represents a summary of the treatments that may be used acutely to control the ventricular response to AFib, prevent thromboembolic events, and provide for acute conversion either pharmacologically or electrically. It includes information on modalities that are currently available and those that are under active development. We anticipate that an active, acute treatment approach to AFib and atrial flutter will become the therapeutic norm in the next few years, especially as the benefits of these interventions are demonstrated in clinical trials.

  3. Effect of gamma irradiation on acute oral toxicity of ethanolic extract of red ginger (zingiber officinale)

    International Nuclear Information System (INIS)

    Red ginger is widely used in traditional medicine to treat various types of diseases. Evaluation of the toxic properties of red ginger is very important to know the negative harmful impact to human health. Therefore, before it is consumed by humans, it is needed to conduct acute oral toxicity of red ginger extract in mice. Thin rhizome of red ginger in poly ethylene plastic packaging was irradiated by gamma rays at a dose of 10 kGy with a dose rate of 10 kGy/h. The ethanol extract of unirradiated as well as irradiated red ginger was then tested for the acute oral toxicity using OECD Guideline test method. The results showed that throughout the 14 days of treatment there was a change in behavior pattern, clinical symptoms and body weight of control mice and treatment groups. Histopathological examination of kidneys, heart, liver, lungs and spleen of the dose less than 1250 mg/kg body weight showed normal condition and no significant side effects observation. While central venous damage and a reduced number of hepatocyte cells in male mice occurred in the test dose higher than 2000 mg/kg body weight, whereas in female mice it occurred in the test group dose higher than 1250 mg/kg bw. Based on renal histology of male and female mice at doses higher than 1250 mg/kg body weight, there were damage to Bowman's capsule, glomerulus, proximal vessel and distal vessels. LD50 of unirradiated and irradiated with 10 kGy of ethanol extract of red ginger were 1887 mg/kg body weight and 2639 mg/kg body weight, respectively, and it can be categorized as moderately toxic. Oral administration of ethanol extract of red ginger with dose of 1250 mg/kg body weight gave an effect in mice organs. From these results it can be concluded that oral administration of both unirradiated and irradiated with a dose 10 kGy of ethanol extract consider safe at a dose less than 1250 mg/kg body weigh.

    The purpose of this study was to determine the simultaneous responses of hepatic metallothionein (MT), zinc (Zn) and glutathione (GSH) in male and female rats to an acute ethanol dose. In male rats, hepatic MT has been shown to be induced by an acute ethanol dose. The Sprague-Dawley rats were fed the Lieber-DeCarli control diet for a five day period and then divided into 6 groups: baseline females and males, ethanol-treated females and males, pair-fed females and males. At t=0, baseline rats were killed, ethanol-treated rats were given ethanol by intragastric tube, and pair-fed rats were given ethanol by intragastric tube, and pair-fed rats were given an isocaloric sucrose solution by intragastric tube. At t=24 h, the ethanol-treated and pair-fed rats were killed. Livers were assayed for MT. Zn and GSH. Concentrations of blood ethanol (BEC) were significantly greater for male than female rats. A two way ANOVA with the independent variables being time and sex was performed to analyze differences for hepatic MT, Zn and GSH. For rats dosed with ethanol and killed 24 h later compared with rats at baseline, hepatic MT was significantly greater and hepatic Zn and GSH were not significantly different. Hepatic MT, Zn and GSH were not significantly different by sex. A significant correlation existed between hepatic Zn/g and MT/g. In conclusion, 24 h after an acute dose of ethanol, female as well as male rats responded with the induction of hepatic MT; and enough cysteine was available for the induction of hepatic MT and the maintenance of hepatic GSH levels. The measurement of Zn bound to hepatic MT rather than total hepatic Zn would be desirable to discern if changes in Zn distribution occur.

    2011-01-01

    Acute viral bronchiolitis represents the most common lower respiratory tract infection in infants and young children and is associated with substantial morbidity and mortality. Respiratory syncytial virus is the most frequently identified virus, but many other viruses may also cause acute bronchiolitis. There is no common definition of acute viral bronchiolitis used internationally, and this may explain part of the confusion in the literature. Most children with bronchiolitis have a self limiting mild disease and can be safely managed at home with careful attention to feeding and respiratory status. Criteria for referral and admission vary between hospitals as do clinical practice in the management of acute viral bronchiolitis, and there is confusion and lack of evidence over the best treatment for this condition. Supportive care, including administration of oxygen and fluids, is the cornerstone of current treatment. The majority of infants and children with bronchiolitis do not require specific measures. Bronchodilators should not be routinely used in the management of acute viral bronchiolitis, but may be effective in some patients. Most of the commonly used management modalities have not been shown to have a clear beneficial effect on the course of the disease. For example, inhaled and systemic corticosteroids, leukotriene receptor antagonists, immunoglobulins and monoclonal antibodies, antibiotics, antiviral therapy, and chest physiotherapy should not be used routinely in the management of bronchiolitis. The potential effect of hypertonic saline on the course of the acute disease is promising, but further studies are required. In critically ill children with bronchiolitis, today there is little justification for the use of surfactant and heliox. Nasal continuous positive airway pressure may be beneficial in children with severe bronchiolitis but a large trial is needed to determine its value. Finally, very little is known on the effect of the various

    Oxidative stress and inflammation are two major etiological factors that are suggested to play key roles in the development of ethanol induced liver injury. Release of proinflammatory cytokine like tumor necrosis factor alpha (TNF-α) and activation of nuclear factor kappa-B (NFκ-B) may strongly intensify inflammation and cell damage. Additionally, reactive oxygen species (ROS) also exerts significant effect in this whole cell signaling machinery. The present study was designed to investigate the protective effects of perillyl alcohol (POH) on ethanol-induced acute liver injury in Wistar rats and its probable mechanism. We have successfully demonstrated that pre-treatment with POH, besides exerting antioxidant activity might be able to modulate TNF-α release and NFκ-B activation. Rats were divided into five groups and treated with ethanol or POH via an intragastric tube for one week. Control group was treated with vehicle, and ethanol treated group was given ethanol (5 g/kg body wt). Animal of treatment groups were pretreated with POH (50 & 100 mg/kg body wt) and have been given ethanol. Serum aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase and hepatic malondialdehyde were increased significantly by ethanol treatment. Ethanol administration decreased hepatic reduced glutathione content and various antioxidant enzymes activity. TNF-α production and NFκ-B activation was also found to be increased after ethanol administration. POH pre-treatment significantly ameliorates ethanol induced acute liver injury possibly by inhibition of lipid peroxidation, replenishment of endogenous enzymatic and non-enzymatic defense system, downregulation of TNF-α as well as NFκ-B.

    Full Text Available Occupational inhalation exposure to noxious agents is not uncommon. Herein, we present a 26-year-old male student who had accidental acute inhalation exposure to a large quantity of titanium ethanolate and hydrogen chloride in chemistry lab. He was referred to the emergency department of our hospital with low-grade fever, dyspnea, headache, fatigue and myalgia. After 24 hrs of symptomatic treatment (oxygen therapy and acetaminophen, the fever was subsided and the patient discharged home in a good clinical condition. The presented symptoms could be interpreted as a form of metal fume fever. It can therefore be concluded that organo-metallic compound of titanium metal may have the potential to produce metal fume fever in human.

    Zebrafish is becoming a species of choice in neurobiological and behavioral studies of alcohol-related disorders. In these efforts, the activity of adult zebrafish is typically quantified using indirect activity measures that are either scored manually or identified automatically from the fish trajectory. The analysis of such activity measures has produced important insight into the effect of acute ethanol exposure on individual and social behavior of this vertebrate species. Here, we leverage a recently developed tracking algorithm that reconstructs fish body shape to investigate the effect of acute ethanol administration on zebrafish tail-beat motion in terms of amplitude and frequency. Our results demonstrate a significant effect of ethanol on the tail-beat amplitude as well as the tail-beat frequency, both of which were found to robustly decrease for high ethanol concentrations. Such a direct measurement of zebrafish motor functions is in agreement with evidence based on indirect activity measures, offering a complementary perspective in behavioral screening.

    During development of the central nervous system, neurons pass through critical periods of vulnerability to environmental factors. Exposure to ethanol during gastrulation or during neuronal generation results in a permanent reduction in the number of neurons in trigeminal-associated cranial nerve nuclei. Normal functioning of the trigeminal system is required for social behavior, the present study examined the effects of acute prenatal exposure to ethanol on social interactions across ontogen...

    Four cases of trauma, where endogenous ethanol production was suspected to have been occurred in association with medical treatment, are reported. To discriminate endogenous ethanol produced de novo by bacteria from exogenous ethanol by drinking, various tissues and body fluids, such as brain and cerebrospinal fluid, together with blood obtained from various locations, were subjected to analysis for both ethanol and n-propanol. The first individual was a 40-year-old man who had been stabbed in the abdomen with a knife and had died of bleeding about 12 h after peritoneotomy, and autopsied 12 h later. In the heart blood, 0.44 mg/g ethanol and 0.005 mg/g n-propanol were detected. Ethanol levels in the cerebrospinal fluid, vitreous humor and brain, reflecting exogenous ethanol levels, were 0.08-0.16 mg/g, and no n-propanol was detected in any of the specimens. The second individual was a 45-year-old man who had been punched hard in the head and face and had died of traumatic shock about 12 h after hospitalization, and autopsied 12 h later. The heart blood concentrations of ethanol and n-propanol were 0.15 and 0.008 mg/g respectively, and a subdural hematoma contained only 0.05 mg/g ethanol and non n-propanol. The third individual was a 34-year-old man who suffered incised wounds of the left arm and head with a sickle and had died of hemorrhagic shock. In the heart blood, 0.30 mg/g ethanol and 0.026 mg/g n-propanol were detected; there was 0.04 mg/g ethanol and no n-propanol in the brain. The fourth individual was a 76-year-old woman who had been hit by a motorcycle and had died of liver rupture about 1 h after admission to a hospital. The heart blood contained 0.22 mg/g ethanol and 0.002 mg/g n-propanol. Only a trace of ethanol and no n-propanol were detected in the pericardial sac fluid and cerebrospinal fluid.

    Using magnetic resonance (MR) imaging and MR spectroscopy, the effects of intoxicating doses of ethanol on the rat brain and the dynamic changes in the cerebral tissues were examined. After ethanol treatment, the cerebral hemispheres, especially the cortex, were shown as high signal intensities on T1-weighted images and low signal intensities on T2-weighted images. Four hr after ethanol treatment, the T1 values significantly decreased in the thalamus and hypothalamus, as compared with the control animals. At one hr, the T2 values significantly decreased in the cortex of the ethanol treated rats. At 4 and 24 hr, the T2 values significantly decreased in the cerebral hemispheres in the ethanol treated rats. In vivo [sup 31]P-MR spectroscopy showed a slight decrease in ATP and phosphocreatine after ethanol treatment. Intracellular pH levels decreased, but returned to normal by 4 hr. In highly sedated animals, early occurrence of acidosis was associated with heavy alkalosis. In vitro [sup 1]H-MR spectra of brain tissue and blood samples revealed many kinds of metabolites. Blood and brain levels of ethanol rose to the peak one 1 hr after ethanol treatment; and no ethanol was detected at 24 hr. Brain levels of acetate were almost unchanged. Blood levels of lactate significantly decreased at 0.5 hr; and brain levels of lactate slightly increased and rose to the peak at 2 hr. Brain N-acetylaspartic acid significantly increased at 0.5 hr and decreased at 4 hr. Electron microscopic findings were edema in both neuronal and glial cells after ethanol treatment, severe congestion, and swelling of mitochondria in capillary endothelial cells. In conclusion, high doses of ethanol may cause circulatory disorders in the rat brain and disturb water balance in the cerebral tissues, resulting in changes in the structure of intracellular water molecules. Ethanol also causes confusion without depletion of high energy phosphate metabolites. (N.K.) 44 refs.

    Chromolaena odorata, a commonly used traditional remedy for different ailments, believed to be quite safe in terms of toxicity was evaluated for acute toxicity and cytotoxic potentials. Acute toxicity was done on albino Wistar rats using the Lorke method while brine shrimps were used to test for cytotoxicity. The results showed that the estimated LD50 for the aqueous and ethanolic extracts was 2154 and > 5000 mg kg(-1) body weight, respectively. Cytotoxicity to brine shrimps showed LC50 values of 324 and 392 ppm for aqueous and ethanolic extracts, respectively. These results indicate the relative non toxic nature of Chromolaena odorata extracts. PMID:26353417

    Larval zebrafish present unique opportunities to study the behavioral responses of a model organism to environmental challenges during early developmental stages. The purpose of the current study was to investigate the locomotor activities of AB strain zebrafish larvae at 5 and 7 days post-fertilization (dpf) in response to light changes under the influence of ethanol, and to explore potential neurological mechanisms that are involved in ethanol intoxication. AB strain zebrafish larvae at both 5 and 7 dpf were treated with ethanol at 0% (control), 0.1%, 0.25%, 0.5%, 1%, and 2% (v/v%). The locomotor activities of the larvae during alternating light-dark challenges, as well as the locomotor responses immediately following the light transitions, were investigated. The levels of various neurotransmitters were also measured in selected ethanol-treated groups. The larvae at 5 and 7 dpf demonstrated similar patterns of locomotor responses to ethanol treatment. Ethanol treatment at 1% increased the swimming distances of the zebrafish larvae in the dark periods, but had no effect on the swimming distances in the light periods. In contrast, ethanol treatment at 2% increased the swimming distances in the light periods, but did not potentiate the swimming activity in the dark periods, compared to controls. Differences in the levels of neurotransmitters that are involved in norepinephrine, dopamine, and serotonin pathways were also observed in groups with different ethanol treatments. These results indicated the behavioral studies concerning the ethanol effects on locomotor activities of zebrafish larvae could be carried out as early as 5 dpf. The 1% and 2% ethanol-treated zebrafish larvae modeled ethanol effects at different intoxication states, and the differences in neurotransmitter levels suggested the involvement of various neurotransmitter pathways in different ethanol intoxication states.

    The present study was undertaken to determine whether subacute treatment with aqueous extract of carob (Ceratonia siliqua L.) pods (AECPs) protects against ethanol (EtOH)-induced oxidative stress in rat liver. Animals were divided into four groups: control, carob, EtOH and EtOH + carob. Wistar rats were intraperitoneally pretreated with AECP (600 mg/kg body weight (bw)) during 7 days and intoxicated for 6 h by acute oral administration of EtOH (6 g/kg bw) 24 h after the last injection. We found that acute administration of EtOH leads to hepatotoxicity as monitored by the increase in the levels of hepatic marker aspartate aminotransferase and alanine aminotransferase as well as hepatic tissue injury. EtOH also increased the formation of malondialdehyde in the liver, indicating an increase in lipid peroxidation and depletion of antioxidant enzyme activities as superoxide dismutase, catalase and glutathione peroxidase. Subacute carob pretreatment prevented all the alterations induced by EtOH and returned their levels to near normal. Importantly, we showed that acute alcohol increased hepatic and plasmatic hydrogen peroxide and free iron levels. The carob pretreatment reversed EtOH effects to near control levels. These data suggest that carob could have a beneficial effect in inhibiting the oxidative damage induced by acute EtOH administration and that its mode of action may involve an opposite effect on plasma and tissue-free iron accumulation. Indeed, carob can be offered as a food additive to protect against EtOH-induced oxidative damage.

Alterations in pro-inflammatory cytokines after acute and chronic EtOH exposure have been heavily investigated. In contrast, little is known about the regulation of neurotransmission and/or modulation by anti-inflammatory cytokines in the brain after an acute EtOH exposure. Recent evidence suggests that interleukin-10 (IL-10), an anti-inflammatory cytokine, is upregulated during withdrawal from chronic E...

  17. The acute toxicity of ethanol extract from irradiated Temulawak (curcuma xanthorrizha roxb.) which have anticancer activity

    International Nuclear Information System (INIS)

    Pasteurization of herbs and herbal medicinal products have been carried out by several herbal industries, but information about the safety of irradiated herbal medicine is still a little, even the influence of gamma irradiation for pasteurization purpose on the toxicity of crude Temulawak has never been investigated. The ethanol extract of Curcuma xanthorrizha Roxb. has cytotoxic activity which potential as an anticancer. In this research, the acute toxicity tests were carried out to the ethanol extract from Curcuma xanthorrizha without irradiation and irradiated with doses of 5 and 10 kGy. The acute toxicity tests of ethanol extract were conducted in mice by observing the effect of extracts on animal behavior (pharmacologic profile) after a single dose of test material, the development of animal body weight and death every day for 14 days and observed several organ weights on day 14. Acute toxicity test results after administration of extracts on male and female mice a dose up to 7500 mg/kg body weight (BW) showed that no deaths and no significant toxic effect, so that the ethanol extract of Curcuma xanthorrizha without irradiation and irradiated with doses of 5 and 10 kGy can be declared safe. Thus LD50 from ethanol extract of Curcuma xanthorrizha without irradiation and irradiated (5 and 10 kGY) in mice was greater than 7500 mg/kg body weight. (author)

    Hippocampal network oscillations at gamma band frequency (γ, 30-80 Hz) are closely associated with higher brain functions such as learning and memory. Acute ethanol exposure at intoxicating concentrations (≥50 mM) impairs cognitive function. This study aimed to determine the effects and the mechanisms of acute ethanol exposure on γ oscillations in an in vitro model. Ethanol (25-100 mM) suppressed kainate-induced γ oscillations in CA3 area of the rat hippocampal slices, in a concentration-dependent, reversible manner. The ethanol-induced suppression was reduced by the D1R antagonist SCH23390 or the PKA inhibitor H89, was prevented by the Akt inhibitor triciribine or the GSk3β inhibitor SB415286, was enhanced by the NMDA receptor antagonist D-AP5, but was not affected by the MAPK inhibitor U0126 or PI3K inhibitor wortmanin. Our results indicate that the intracellular kinases Akt and GSk3β play a critical role in the ethanol-induced suppression of γ oscillations and reveal new cellular pathways involved in the ethanol-induced cognitive impairment.

    Full Text Available Summary: The acute and subchronic toxicities of the ethanol leaf extract of Spathodea campanulata, a popular Nigerian traditional anti-convulsant remedy was investigated. For the acute toxicity study, 1000-5000 mg/kg of the ethanol leaf extract were administered to rats and obvious toxic symptoms and mortality 24 hours post-adminstration of the extract were determined. The median lethal dose (LD50 of the extract was determined. In the subchronic study, 750-3000 mg/kg of the extract were administered daily for 90 days. The food and water consumption, body weight changes, as well as heamatological and biochemical parameters were determined periodically. The phytotochemical constituents of the extract were also investigated. Phytochemical analysis revealed the presence of tannins, saponins, anthraquinone glycosides, and flavonoids.. The estimated LD50 of the extract was 4466.84 mg/kg. There was no mortality during the period of study but the animals showed signs of anorexia, weakness, sluggishness and significant (p<0.05 reduction in food and water intake and body weight. The effects on haemoglobin concentration, PCV, RBC and WBC counts were non significant (P>0.05. The extract caused significant (p<0.05 increases in serum liver enzymes, AST, ALP and ALT. These changes showed recovery after 28 days post-treatment. These results suggest that the leaf extract of S. campanulata is safe in the treatment of epilepsy. Industrial relevance: Epilepsy is a chronic disorder that requires life-long management. The available anti-epileptic drugs (AEDs are not only limited by adverse effects, but are not readily accessible in resource poor communities where this disease appears more prevalent. The use of medicinal plants especially Spathodea campanulata in the treatment of epilepsy is very popular in Nigeria. Compared to AEDs, it is very cheap, readily available and relatively free from adverse effects. The results of the present study will enable the industry

    Alcohol addiction is a major unmet medical and economic issue for which very few efficacious pharmacological treatment options are currently available. The development and identification of new compounds and drugs to treat alcohol addiction is hampered by the high costs and low amenability of traditional laboratory rodents to high-throughput behavioral screens. The zebrafish represents an excellent compromise between systems complexity and practical simplicity by overcoming many limitations inherent in these rodent models. In this chapter, we review current advances in the behavioral and neurochemical characterization of ethanol-induced changes in zebrafish. We also discuss the basic principles and methods of and the most recent advances in using paradigms with which one can screen for compounds altering acute and chronic ethanol-induced effects in zebrafish.

    Expression of genes encoding the individual subunits of ionotropic GABAA receptor was assessed after acute and chronic intoxication of rats with ethanol. The chronic 1-month-long exposure to ethanol signifi cantly decreased (by 38%) expression of Gabrb1 gene in the hippocampus. Acute exposure to ethanol elevated expression of genes Gabrb1 (by 1.7 times), Gabra1 (by 3.8 times), and Gabra4 (by 6.5 times), although it diminished expression of Gabra2 gene by 1.4 times. In preliminarily alcoholized rats, acute intoxication with ethanol enhanced expression of genes Gabrb1 and Gabra5 by 1.7 and 8.7 times, respectively. There was neither acute nor chronic effect of ethanol on expression of gene Gabra3. PMID:26902358

  5. Basics of acute stroke treatment

    International Nuclear Information System (INIS)

    Acute stroke presents an emergency that requires immediate referral to a specialized hospital, preferably with a stroke unit. Disability and mortality are reduced by 30% in patients treated in stroke units compared to those treated on regular wards, even if a specialized team is present on the ward. Systolic blood pressure may remain high at 200-220 mmHg in the acute phase and should not be lowered too quickly. Further guidelines for basic care include: optimal O2 delivery, blood sugar levels below 100-150 mg%, and lowering body temperature below 37.5 C using physical means or drugs. Increased intracranial pressure should be treated by raising the upper body of the patient, administration of glycerol, mannitol, and/or sorbitol, artificial respiration, and special monitoring of Tris buffer. Decompressive craniectomy may be considered in cases of ''malignant'' media stroke and expansive cerebellar infarction. Fibrinolysis is the most effective stroke treatment and is twice as effective in the treatment of stroke than myocardial infarction. Fibrinolysis may be initiated within 3 h of a stroke in the anterior circulation. If a penumbra is detectable by ''PWI-DWI mismatch MRI,'' specialized hospitals may perform fibrinolysis up to 6 h after symptom onset. In cases of stroke in the basilar artery, fibrinolysis may be performed even later after symptom onset. Intra-arterial fibrinolysis is performed in these cases using rt-PA or urokinase. Follow-up treatment of stroke patients should not only address post-stroke depression and neuropsychological deficits, but also include patient education about risk factors such as high blood pressure, diabetes mellitus, and cardiac arrhythmias.

    Full Text Available  Introduction: Patients with epilepsy can have impaired cognitive abilities. Many factors contribute to this impairment, including the adverse effects of antiepileptic drugs like Gabapentin (GBP. Apart from anti-epilectic action, Gabapentin is used to relieve ethanol withdrawal syndrome. Because both GBP and ethanol act on GABA ergic system, the purpose of this study was to evaluate their effect and interaction on spatial learning and memory. Material and Methods: Male Sprague-Dawley rats were trained in the Morris water maze for 5 consecutive days. On the sixth day, a probe test was performed to assess the retention phase or spatial rats’ memory ability. Ethanol (1.5 g/kg i.p. and GBP (30 mg/kg i.p. was administered each day 30 and 40 minutes before testing respectively. Results: Acute ethanol administration selectively impaired spatial memory (p<0.05, yet it failed to impair the acquisition phase (learning. Contradictorily GBP selectively impaired learning on second and forth days. Conclusion: These findings demonstrate that GBP and acute ethanol impair different phases of learning probably by modifying different neuronal pathways in cognitive areas of the brain.

  8. Effects of ethanol on voltage-sensitive Na-channels in cultured skeletal muscle: Up-regulation as a result of chronic treatment

    International Nuclear Information System (INIS)

    The effects of acute and chronic treatment with ethanol were studied on the number and activity of tetrodotoxin-sensitive Na-channels in cultured rat skeletal muscle. The number of channels was determined by measurements of specific binding of [3H] saxitoxin (STX) in whole cell preparations. Measurements were also made of the frequency and rate of rise of spontaneously occurring action potentials, which are the physiologic expression of Na-channel density. Acute ethanol (37.5-150 mM), while causing depolarization of membrane potential and blockade of electrical activity, was without effect on specific STX binding. Neither methanol, acetaldehyde nor ethylene glycol had significant effects on these properties when given acutely in the same concentrations as ethanol. Chronic ethanol caused dose-related increases in STX binding and action potential properties with maximal levels being attained after 3 days of treatment at a concentration of 150 mM. On removal of ethanol from the culture medium all properties returned to control levels after 48 hr. Both increased external K+ and tetrodotoxin, which up-regulate Na-channels by reducing cytosolic Ca++, potentiated the ethanol-induced increase in Na-channel density. The increase in STX binding was not associated with changes in affinity of the binding sites for the ligand but was completely prevented by treatment with cycloheximide and actinomycin D. The results demonstrate that ethanol interacts with the cell membrane to induce synthesis of STX-binding sites

    The endogenous cannabinoid (eCB) system has been suggested to play a key role in ethanol preference and intake, the acute effects of ethanol, and in the development of withdrawal symptoms following ethanol dependence. Ethanol-dependent alterations in glutamatergic signaling within the lateral/basolateral nucleus of the amygdala (BLA) are critical for the development and expression of withdrawal-induced anxiety. Notably, the eCB system significantly regulates both glutamatergic and GABAergic synaptic activity within the BLA. Chronic ethanol exposure significantly alters eCB system expression within regions critical to the expression of emotionality and anxiety-related behavior, including the BLA. Here, we investigated specific interactions between the BLA eCB system and its functional regulation of synaptic activity during acute and chronic ethanol exposure. In tissue from ethanol naïve-rats, a prolonged acute ethanol exposure caused a dose dependent inhibition of glutamatergic synaptic activity via a presynaptic mechanism that was occluded by CB1 antagonist/inverse agonists SR141716a and AM251. Importantly, this acute ethanol inhibition was attenuated following 10 day chronic intermittent ethanol vapor exposure (CIE). CIE exposure also significantly down-regulated CB1-mediated presynaptic inhibition at glutamatergic afferent terminals but spared CB1-inhibition of GABAergic synapses arising from local inhibitory-interneurons. CIE also significantly elevated BLA N-arachidonoylethanolamine (AEA or anandamide) levels and decreased CB1 receptor protein levels. Collectively, these data suggest a dynamic regulation of the BLA eCB system by acute and chronic ethanol. PMID:26707595

  11. Acute effects of ethanol on hepatic uptake and distribution of narcotics in the isolated perfused rabbit liver

    Kreek, M.J.; Rothschild, M.A.; Oratz, M.; Mongelli, J.; Handley, A.C.

    This study was performed as an initial step in systematically defining the hepatic interactions between ethanol and opioids using a controlled in vitro system. The acute effects of ethanol on the initial uptake and distribution of long- and short-acting narcotics were studied using isolated rabbit liver perfused with rabbit blood without or with ethanol. A pulse injection of 1.5 mg of 14C-labeled narcotic (methadone, 1-alpha-acetylmethadol (LAAM), morphine, or meperidine) was made into the portal vein cannula followed by perfusion for 2 min. Radioactivity was determined in liver homogenates and subcellular fractions; methadone and its metabolites were measured by thin-layer chromatography with zonal scanning in each fraction. Ethanol preperfusion and concomitant ethanol perfusion did not effect hepatic uptake of methadone, LAAM, morphine, or meperidine. Although subcellular localization of morphine and meperidine differed from that of methadone and LAAM, perfusion with ethanol did not alter the acute hepatic uptake and distribution of any of the narcotics. These findings suggest that acute exposure to ethanol does not alter the acute hepatic disposition of narcotics.

Prolonged alcohol abuse can cause liver fibrosis due to deregulated matrix remodeling. Previous studies demonstrated that moderate ethanol feeding enhances liver fibrogenic markers and frank fibrosis independent of differences in CCl₄-induced liver injury. Our objective was to determine whether or not other phases of the hepatic wound healing response were affected by moderate ethanol after CCl₄ exposure. Mice were fed moderate ethanol (2% v/v) for two days and then were exposed to CCl₄ and euthanized 24-96 h later. Liver injury was not different between pair- and ethanol-fed mice; however, removal of necrotic tissue was delayed after CCl₄-induced liver injury in ethanol-fed mice. Inflammation, measured by TNFα mRNA and protein and hepatic Ly6c transcript accumulation, was reduced and associated with enhanced hepatocyte apoptosis after ethanol feeding. Hepatocytes entered the cell cycle equivalently in pair- and ethanol-fed mice after CCl₄ exposure, but hepatocyte proliferation was prolonged in livers from ethanol-fed mice. CCl₄-induced hepatic stellate cell activation was increased and matrix remodeling was prolonged in ethanol-fed mice compared to controls. Taken together, moderate ethanol affected each phase of the wound healing response to CCl₄. These data highlight previously unknown effects of moderate ethanol exposure on hepatic wound healing after acute hepatotoxicant exposure.

    Full Text Available Acute ethanol intoxication increases the production of reactive oxygen species (ROS. Hemorrhagic shock with subsequent resuscitation (H/R also induces ROS resulting in cellular and hepatic damage in vivo. We examined the role of acute ethanol intoxication upon oxidative stress and subsequent hepatic cell death after H/R. 14 h before H/R, rats were gavaged with single dose of ethanol or saline (5 g/kg, EtOH and ctrl; H/R_EtOH or H/R_ctrl, resp.. Then, rats were hemorrhaged to a mean arterial blood pressure of 30±2 mmHg for 60 min and resuscitated. Two control groups underwent surgical procedures without H/R (sham_ctrl and sham_EtOH, resp.. Liver tissues were harvested at 2, 24, and 72 h after resuscitation. EtOH-gavage induced histological picture of acute fatty liver. Hepatic oxidative (4-hydroxynonenal, 4-HNE and nitrosative (3-nitrotyrosine, 3-NT stress were significantly reduced in EtOH-gavaged rats compared to controls after H/R. Proapoptotic caspase-8 and Bax expressions were markedly diminished in EtOH-gavaged animals compared with controls 2 h after resuscitation. EtOH-gavage increased antiapoptotic Bcl-2 gene expression compared with controls 2 h after resuscitation. iNOS protein expression increased following H/R but was attenuated in EtOH-gavaged animals after H/R. Taken together, the data suggest that acute EtOH-gavage may attenuate H/R-induced oxidative stress thereby reducing cellular injury in rat liver.

    Chronic alcoholics who also binge drink (i.e., acute on chronic) are prone to an exacerbated liver injury but its mechanism is not understood. We therefore investigated the in vivo effects of chronic and binge ethanol ingestion and compared to chronic ethanol followed by three repeat binge ethanol on the liver of male C57/BL6 mice fed ethanol in liquid diet (4%) for four weeks followed by binge ethanol (intragastric administration, 3.5 g/kg body weight, three doses, 12h apart). Chronic followed by binge ethanol exacerbated fat accumulation, necrosis, decrease in hepatic SAM and SAM:SAH ratio, increase in adenosine levels, and elevated CYP2E1 levels. Histone H3 lysine acetylation (H3AcK9), dually modified phosphoacetylated histone H3 (H3AcK9/PS10), and phosphorylated H2AX increased after binge whereas phosphorylation of histone H3 ser 10 (H3S10) and H3 ser 28 (H3S28) increased after chronic ethanol-binge. Histone H3 lysine 4 and 9 dimethylation increased with a marked dimethylation in H3K9 in chronic ethanol binge group. Trimethylated histone H3 levels did not change. Nuclear levels of histone acetyl transferase GCN5 and histone deacetylase HDAC3 were elevated whereas phospho-CREB decreased in a distinctive manner. Taken together, acute on chronic ethanol ingestion caused amplification of liver injury and elicited characteristic profiles of histone modifications, metabolic alterations, and changes in nuclear protein levels. These findings demonstrate that chronic ethanol exposure renders liver more susceptible to repeat acute/binge ethanol induced acceleration of alcoholic liver disease.

    The diagnosis of acute pancreatitis is based on anamnestic, clinical and chemical data. Ultrasound and computed tomography permit direct visualisation of the pancreas and establish the diagnosis. In cases of haemorrhagic-necrotising pancreatitis they demonstrate the extent of morphological changes and permit exclusion of other causes of an acute abdomen. The imaging methods support indications for operation in cases of subtotal or total parenchymatous necrosis and in pancreatic abscesses. Conservative expectant approaches in patients with severe clinical course and slight morphological changes as well as in agreement of clinical and morphological findings are facilitated. Complete demonstration of parenchymatous and peripancreatic necroses furnishes useful additional information for total extirpation. Gallstone disease can be demonstrated or excluded preoperatively. Since introduction of ultrasound and computed tomography for the diagnosis of acute pancreatitis a marked diminution of early surgical intervention and delayed operation has been achieved.

    Ethanol intake is associated with increase in blood pressure, through unknown mechanisms. We hypothesized that acute ethanol intake enhances vascular oxidative stress and induces vascular dysfunction through renin–angiotensin system (RAS) activation. Ethanol (1 g/kg; p.o. gavage) effects were assessed within 30 min in male Wistar rats. The transient decrease in blood pressure induced by ethanol was not affected by the previous administration of losartan (10 mg/kg; p.o. gavage), a selective AT{sub 1} receptor antagonist. Acute ethanol intake increased plasma renin activity (PRA), angiotensin converting enzyme (ACE) activity, plasma angiotensin I (ANG I) and angiotensin II (ANG II) levels. Ethanol induced systemic and vascular oxidative stress, evidenced by increased plasma thiobarbituric acid-reacting substances (TBARS) levels, NAD(P)H oxidase‐mediated vascular generation of superoxide anion and p47phox translocation (cytosol to membrane). These effects were prevented by losartan. Isolated aortas from ethanol-treated rats displayed increased p38MAPK and SAPK/JNK phosphorylation. Losartan inhibited ethanol-induced increase in the phosphorylation of these kinases. Ethanol intake decreased acetylcholine-induced relaxation and increased phenylephrine-induced contraction in endothelium-intact aortas. Ethanol significantly decreased plasma and aortic nitrate levels. These changes in vascular reactivity and in the end product of endogenous nitric oxide metabolism were not affected by losartan. Our study provides novel evidence that acute ethanol intake stimulates RAS activity and induces vascular oxidative stress and redox-signaling activation through AT{sub 1}-dependent mechanisms. These findings highlight the importance of RAS in acute ethanol-induced oxidative damage. -- Highlights: ► Acute ethanol intake stimulates RAS activity and vascular oxidative stress. ► RAS plays a role in acute ethanol-induced oxidative damage via AT{sub 1} receptor activation.

    Objective: To ensure the safety and evaluate the anti oxidant activity of Terminalia paniculata (T.paniculata) ethanolic extract in Sprague Dawley rats. Methods: The solvent extracts (hexane, ethyl acetate and ethanol) of T. paniculata were subjected to phytochemical analysis and their DPPH radical scavenging activity was assayed. The oral acute toxicity was evaluated using ethanolic extract of T. paniculata. Results:Ethyl acetate and ethanolic extracts showed more phytochemicals, whereas highest DPPH scavenging activity was found in ethanolic extract. In an acute toxicity study, T. paniculata ethanolic extract was orally administered (1 000 mg/kg body weight) to rats and observed for 72 h for any toxic symptoms and the dose was continued up to 14 d. On the 15th day rats were sacrificed and blood samples were collected from control and test animals and analyzed for some biochemical parameters. We did not observe any behavioral changes in test groups in comparison with their controls. Also, there were no significant alterations in biochemical, hematological (hemoglobin content and blood cells count) and liver function parameters such as serum glutamate pyruvate transaminase, serum glutamate oxaloacetate transaminase, alkaline phosphatase, total proteins, albumin and bilirubin levels between T. paniculata ethanolic extract treated and normal control groups. Conclusions:Together our results demonstrated that T. paniculata ethanolic possessed potent antioxidant activity and it was safer and non toxic to rats even at higher doses and therefore could be well considered for further investigation for its medicinal and therapeutic efficacy.

    Our recent studies indicate that hydrogen peroxide (H2O2) only at high concentrations can cause oxidative stress in renal epithelial cells and induce apoptosis of podocytes. Consistently, the present study shows that H2O2, even at 1 mM, failed to induce intracellular oxidative stress and apoptosis of the podocytes due to efficient activity of catalase, an enzyme which degrades H2O2 to produce water and oxygen (O2). However, H2O2 acted as a source of O2 to allow acute ethanol to induce superox...

    Full Text Available Gallstones are the commonest cause of acute pancreatitis (AP, a potentially life-threatening condition, worldwide. The pathogenesis of acute pancreatitis has not been fully understood. Laboratory and radiological investigations are critical for diagnosis as well prognosis prediction. Scoring systems based on radiological findings and serologic inflammatory markers have been proposed as better predictors of disease severity. Early endoscopic retrograde cholangiopancreatography (ERCP is beneficial in a group of patients with gallstone pancreatitis. Laparoscopic cholecystectomy with preoperative endoscopic common bile duct clearance is recommended as a treatment of choice for acute biliary pancreatitis. The timing of cholecystectomy, following ERCP, for biliary pancreatitis can vary markedly depending on the severity of pancreatitis

    Full Text Available The objective of this study was to evaluate the acute and subacute toxicity (28 days of the ethanol extract of Z. zerumbet rhizomes (EEZZ via the oral route in Wistar rats of both sexes. In the acute toxicity study, Wistar rats were administered a single dose of 15 g kg−1 of body weight by gavage, and were monitored for 14 days. EEZZ did not produce any toxic signs or deaths; the 50% lethal dose must be higher than 15 g kg−1. In the subchronic toxicity study, EEZZ was administered by gavage at doses of 1000, 2000 and 3000 mg/kg daily for 4 weeks to Wistar rats. The subacute treatment with EEZZ did not alter either the body weight gain or the food and water consumption. The hematological and biochemical analysis did not show significant differences in any of the parameters examined in female or male groups. Necropsy and histopathological examination, did not reveal any remarkable and treatment related changes. A no-observed adverse-effect level for EEZZ is 3000 mg kg−1 for rats under the conditions of this study. Hence, consumption of EEZZ for various medicinal purposes is safe.

  9. Effects of acute or chronic ethanol exposure during adolescence on behavioral inhibition and efficiency in a modified water maze task.

    Full Text Available Ethanol is well known to adversely affect frontal executive functioning, which continues to develop throughout adolescence and into young adulthood. This is also a developmental window in which ethanol is misused by a significant number of adolescents. We examined the effects of acute and chronic ethanol exposure during adolescence on behavioral inhibition and efficiency using a modified water maze task. During acquisition, rats were trained to find a stable visible platform onto which they could escape. During the test phase, the stable platform was converted to a visible floating platform (providing no escape and a new hidden platform was added in the opposite quadrant. The hidden platform was the only means of escape during the test phase. In experiment 1, adolescent animals received ethanol (1.0 g/kg 30 min before each session during the test phase. In experiment 2, adolescent animals received chronic intermittent ethanol (5.0 g/kg for 16 days (PND30 To PND46 prior to any training in the maze. At PND72, training was initiated in the same modified water maze task. Results from experiment 1 indicated that acute ethanol promoted behavioral disinhibition and inefficiency. Experiment 2 showed that chronic intermittent ethanol during adolescence appeared to have no lasting effect on behavioral disinhibition or new spatial learning during adulthood. However, chronic ethanol did promote behavioral inefficiency. In summary, results indicate that ethanol-induced promotion of perseverative behavior may contribute to the many adverse behavioral sequelae of alcohol intoxication in adolescents and young adults. Moreover, the long-term effect of adolescent chronic ethanol exposure on behavioral efficiency is similar to that observed after chronic exposure in humans.

    Highlights: • Ethanol administration increased GPD1 mRNA expression. • Ethanol administration increased glucose incorporation into TG glycerol moieties. • No increase in hepatic TG levels was observed in ethanol-injected GPD1 null mice. • We propose that GPD1 is required for ethanol-induced TG accumulation in the liver. - Abstract: Acute ethanol consumption leads to the accumulation of triglycerides (TGs) in hepatocytes. The increase in lipogenesis and reduction of fatty acid oxidation are implicated as the mechanisms underlying ethanol-induced hepatic TG accumulation. Although glycerol-3-phosphate (Gro3P), formed by glycerol kinase (GYK) or glycerol-3-phosphate dehydrogenase 1 (GPD1), is also required for TG synthesis, the roles of GYK and GPD1 have been the subject of some debate. In this study, we examine (1) the expression of genes involved in Gro3P production in the liver of C57BL/6J mice in the context of hepatic TG accumulation after acute ethanol intake, and (2) the role of GPD1 in the progression of ethanol-induced fatty liver using GPD1 null mice. As a result, in C57BL/6J mice, ethanol-induced hepatic TG accumulation began within 2 h and was 1.7-fold greater than that observed in the control group after 6 h. The up-regulation of GPD1 began 2 h after administering ethanol, and significantly increased 6 h later with the concomitant escalation in the glycolytic gene expression. The incorporation of {sup 14}C-labelled glucose into TG glycerol moieties increased during the same period. On the other hand, in GPD1 null mice carrying normal GYK activity, no significant increase in hepatic TG level was observed after acute ethanol intake. In conclusion, GPD1 and glycolytic gene expression is up-regulated by ethanol, and GPD1-mediated incorporation of glucose into TG glycerol moieties together with increased lipogenesis, is suggested to play an important role in ethanol-induced hepatic TG accumulation.

    2011-01-01

    Full Text Available Pelvic inflammatory disease (PID, one of the most common infections in nonpregnant women of reproductive age, remains an important public health problem. It is associated with major long-term sequelae, including tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. In addition, treatment of acute PID and its complications incurs substantial health care costs. Prevention of these long-term sequelae is dependent upon development of treatment strategies based on knowledge of the microbiologic etiology of acute PID. It is well accepted that acute PID is a polymicrobic infection. The sexually transmitted organisms, Neisseria gonorrhoeae and Chlamydia trachomatis, are present in many cases, and microorganisms comprising the endogenous vaginal and cervical flora are frequently associated with PID. This includes anaerobic and facultative bacteria, similar to those associated with bacterial vaginosis. Genital tract mycoplasmas, most importantly Mycoplasma genitalium, have recently also been implicated as a cause of acute PID. As a consequence, treatment regimens for acute PID should provide broad spectrum coverage that is effective against these microorganisms.

    Acute leukemias are characterized by accumulation of immature cells (blasts) and reduced production of healthy hematopoietic elements. According to the lineage origin, two major leukemias can be distinguished: acute myeloid leukemia (AML) and acute lymphoid leukemia (ALL). Although the survival rate for pediatric ALL is close to 90%, half of the young adults with AML or ALL and approximately 90% of older patients with AML or ALL still die of their disease, raising the need for innovative therapeutic approaches. As almost all leukemic blasts express specific surface antigens, targeted immunotherapy appears to be particularly promising. However, published results of immunotherapy alone are generally modest. Radioimmunotherapy (RIT) brings additional therapeutic mechanisms using radiolabeled monoclonal antibodies (mAbs) directed to tumor antigens, thus adding radiobiological cytotoxicity to immunologic cytotoxicity. Because of the high radiosensitivity of tumor cells and the diffuse widespread nature of the disease, making it rapidly accessible to circulating radiolabeled mAbs, acute leukemias represent relevant indications for RIT. With the development of recombinant and humanized mAbs, innovative radionuclides, and more efficient radiolabeling and pretargeting techniques, RIT has significantly improved over the last 10 years. Different approaches of α and β RIT targeting CD22, CD33, CD45, or CD66 antigens have already been evaluated or are currently being developed in the treatment of acute leukemia. This review summarizes the preclinical and clinical studies demonstrating the potential of RIT in treatment of AML and ALL. PMID:26897718

    2007-07-01

    Full Text Available The pathogenesis of acute pancreatitis relates to the inappropriate activation of trypsinogen to trypsin and a lack of the prompt elimination of the active trypsin inside the pancreas. Therefore, trypsin is believed to be the key enzyme in the initiation and exacerbation of acute pancreatitis by activating pancreatic zymogens. The activation of digestive enzymes causes pancreatic injury and results in an inflammatory response. The acute inflammatory response in the pancreas induces the systemic production of cytokines causing substantial tissue damage, and may progress beyond the pancreas to a systemic inflammatory response syndrome (SIRS, multi-organ failure (MOF or death [1]. In several studies, protease inhibitors have not been shown to be of significant value in the treatment of acute pancreatitis and are not available in the United States [2]. Several guidelines [3, 4, 5, 6, 7, 8, 9, 10, 11, 12] on the treatment of acute pancreatitis do not recommend them and the debate about the use of protease inhibitors is mentioned.

    Symptoms of alcohol withdrawal range in severity from mild "hangover" to fatal delirium tremens (DTs). Tremor, hallucinosis, and seizures usually occur within 48 hours of abstinence. Seizures tend to be generalized without focality, occurring singly or in a brief cluster, but status epilepticus is not unusual. DTs usually appears after 48 hours of abstinence and consists of marked inattentiveness, agitation, hallucinations, fluctuating level of alertness, marked tremulousness, and sympathetic overactivity. The mainstay of treatment for alcohol withdrawal is benzodiazepine pharmacotherapy, which can be used to control mild early symptoms, to prevent progression to DTs, or to treat DTs itself. Alternative less evidence-based pharmacotherapies include phenobarbital, anticonvulsants, baclofen, gamma-hydroxybutyric acid, beta-blockers, alpha-2-agonists, and N-methyl-d-aspartate receptor blockers. Treatment of DTs is a medical emergency requiring heavy sedation in an intensive care unit, with close attention to autonomic instability, fever, fluid loss, and electrolyte imbalance. Frequent comorbid disorders include hypoglycemia, liver failure, pancreatitis, sepsis, meningitis, intracranial hemorrhage, and Wernicke-Korsakoff syndrome. PMID:25307572

    Ethanolic extract of Curcuma xanthorrhiza was used to evaluate the analgesic and toxicity effects in vivo. The extract was standardized using GC-MS, which showed that 1 mg of Curcuma xanthorrhiza ethanolic extract contains 0.1238 mg of xanthorrhizol. The analgesic activity was studied in rats using three different models, namely the hot plate test, tail flick test and formalin-induced pain test. The acute oral toxicity was examined by the oral administration of standardized Curcuma xanthorrhiza ethanolic extract in mice at doses ranging from 300-5,000 mg/kg and observation for 14 days. Standardized Curcuma xanthorrhiza ethanolic extract did not show significant analgesic effect in the hot plate and tail flick tests. However, in the formalin-induced pain test, Curcuma xanthorrhiza ethanolic extract significantly (P Curcuma xanthorrhiza ethanolic extract did not show any toxic effects in mice at 5 g/kg. These experimental results suggest that the standardized Curcuma xanthorrhiza ethanolic extract showed peripheral and central antinociceptive activity associated with neurogenic pain as well as a relative absence of toxic effects which could compromise the medicinal use of this plant in folk medicine.

    Full Text Available BACKGROUND: In humans, ethanol exposure during pregnancy causes a spectrum of developmental defects (fetal alcohol syndrome or FAS. Individuals vary in phenotypic expression. Zebrafish embryos develop FAS-like features after ethanol exposure. In this study, we ask whether stage-specific effects of ethanol can be identified in the zebrafish, and if so, whether they allow the pinpointing of sensitive developmental mechanisms. We have therefore conducted the first large-scale (>1500 embryos analysis of acute, stage-specific drug effects on zebrafish development, with a large panel of readouts. METHODOLOGY/PRINCIPAL FINDINGS: Zebrafish embryos were raised in 96-well plates. Range-finding indicated that 10% ethanol for 1 h was suitable for an acute exposure regime. High-resolution magic-angle spinning proton magnetic resonance spectroscopy showed that this produced a transient pulse of 0.86% concentration of ethanol in the embryo within the chorion. Survivors at 5 days postfertilisation were analysed. Phenotypes ranged from normal (resilient to severely malformed. Ethanol exposure at early stages caused high mortality (≥88%. At later stages of exposure, mortality declined and malformations developed. Pharyngeal arch hypoplasia and behavioral impairment were most common after prim-6 and prim-16 exposure. By contrast, microphthalmia and growth retardation were stage-independent. CONCLUSIONS: Our findings show that some ethanol effects are strongly stage-dependent. The phenotypes mimic key aspects of FAS including craniofacial abnormality, microphthalmia, growth retardation and behavioral impairment. We also identify a critical time window (prim-6 and prim-16 for ethanol sensitivity. Finally, our identification of a wide phenotypic spectrum is reminiscent of human FAS, and may provide a useful model for studying disease resilience.

    Full Text Available In the present study, ethanolic nanovesicles of Aceclofenac developed for the site specific delivery to joints for effective treatment of osteoarthritis. Ethanolic nano-vesicles were prepared by solvent dispersion method. Vesicles were characterized for vesicular size, surface morphology, size and size distribution, zeta potential, entrapment efficiency. Formulations were also evaluated for drug-vesicle (excipients interaction, in vitro permeation, in vitro deposition. The TEM showed dark vesicular structures by which it is possible to notice the outer most bilayer. In the ethanol concentration range of 20-40%, the size of the vesicles increased with decreasing ethanol concentration, with the largest vesicles in preparations containing 20% ethanol (809.34±2.329 nm and the smallest in preparations containing 40% ethanol (627±3.684 nm. Zeta potential of formulations shows negative value, which indicates that, the higher concentration of ethanol make the negative charge on vesicles surface. The entrapment was found to increase with increase in ethanol concentration, however percent entrapment decreased when ethanol concentration exceeded 40%. The FTIR spectra reveled no considerable change in IR peaks of Aceclofenac loaded ethanolic vesicles when compared to pure drugs there by indicating absence of any interaction.

    Full Text Available BACKGROUND: Many donor organs come from youths involved in alcohol-related accidental death. The use of cardiac allografts for transplantation from donors after acute poisoning is still under discussion while acute ethanol intoxication is associated with myocardial functional and morphological changes. The aims of this work were 1 to evaluate in rats the time-course cardiac effects of acute ethanol-exposure and 2 to explore how its abuse by donors might affect recipients in cardiac pump function after transplantation. METHODS: Rats received saline or ethanol (3.45 g/kg, ip. We evaluated both the mechanical and electrical aspects of cardiac function 1 h, 6 h or 24 h after injection. Plasma cardiac troponin-T and glucose-levels were measured and histological examination of the myocardium was performed. In addition, heart transplantation was performed, in which donors received ethanol 6 h or 24 h prior to explantation. Graft function was measured 1 h or 24 h after transplantation. Myocardial TBARS-concentration was measured; mRNA and protein expression was assessed by quantitative real-time PCR and Western blot, respectively. RESULTS: Ethanol administration resulted in decreased load-dependent (-34 ± 9% and load-independent (-33 ± 12% contractility parameters, LV end-diastolic pressure and elevated blood glucose levels at 1 h, which were reversed to the level of controls after 6 h and 24 h. In contrast to systolic dysfunction, active relaxation and passive stiffness are slowly recovered or sustained during 24 h. Moreover, troponin-T-levels were increased at 1 h, 6 h and 24 h after ethanol injection. ST-segment elevation (+47 ± 10%, elongated QT-interval (+38 ± 4%, enlarged cardiomyocyte, DNA-strand breaks, increased both mRNA and protein levels of superoxide dismutase-1, glutathione peroxydase-4, cytochrome-c-oxidase and metalloproteinase-9 were observed 24 h following ethanol-exposure. After heart transplantation, decreased myocardial

    Full Text Available Acute gallstone pancreatitis represents about half of all pancreatitis and it has still a high mortality despite the progress in the early diagnosis and proper treatment. There are certain difficulties in choosing the optimal treatment because of the polymorphism of presentations, the diversity of pathological types, the particularities of the cases and the risks that are to assume in any kind of treatment strategy the doctor choose. Another difficult factor to assume is the moment of the interventional approach, which is still controversial due to its high dependence of too many factors. The conservative treatment of acute gallstone pancreatitis is not usually followed by the remission of the inflammatory process but leads to the aggravation of the disease. The removal of the cause of the ampular obstruction (the stone can be spontaneously in some cases; however, in most cases of severe disease the removal requires surgical or endoscopic interventional approach. The most important controversy lies between these two methods, and to choose the proper moment of each intervention.

    Full Text Available Objectives: Synedrella nodiflora (L Gaertn (family Asteraceae is traditionally used in Ghana for the management of epilepsy, hiccup and threatened abortion. The anticonvulsant and other related neuro-pharmacological effects of a hydro-ethanolic extract in murine models have been established. To this end, we evaluated a sub-acute toxicity of the hydro-ethanolic whole plant extract in rats. Materials and Methods: The effects of a continuous 14-day oral administration of the extract (100, 300 and 1000 mg/kg on haematological and serum biochemical parameters were measured. Results: The extract produced no mortality in the rats treated during the study period. The extract also did not significantly affect any of the haematological and serum biochemical indices measured. Conclusion: This result suggests that a 14-day oral administration of the hydro-ethanolic extract of Synedrella nodiflora is relatively safe in Sprague-Dawley male rats under the present laboratory conditions.

    2014-10-01

    Furfural is an inhibitor of growth and ethanol production by Zymomonas mobilis. This study used a naturally occurring (not GMO) biological pre-treatment to reduce that amount of furfural in a model fermentation broth. Pre-treatment involved inoculating and incubating the fermentation broth with strains of Leuconostoc mesenteroides or Leuconostoc pseudomesenteroides. The Leuconostoc strains converted furfural to furfuryl alcohol without consuming large amounts of dextrose in the process. Coupling this pre-treatment to ethanolic fermentation reduced furfural in the broth and improved growth, dextrose uptake and ethanol formation. Pre-treatment permitted ethanol formation in the presence of 5.2 g L(-1) furfural, which was otherwise inhibitive. The pre-treatment and presence of the Leuconostoc strains in the fermentation broth did not interfere with Z. mobilis ethanolic fermentation or the amounts of ethanol produced. The method suggests a possible technique for reducing the effect that furfural has on the production of ethanol for use as a biofuel.

    Diagnosis and treatment results of 57 patients with acute diffuse brain injury have been analyzed. Patients were divided into two groups: first study period 2000-2005; second study period 2006-2010. The main differences between the first and the second study periods were in health condition and brain functions monitoring parameters, therapy approaches and goals. Increasing of axial and lateral dislocation symptoms during progression from the first type of diffuse injury to the fourth one is related to intracranial hypertension (ICH) occurrence rate and significance it's significance. During the second study period, ICH was found in 25% patients with the second type of injury, 57% patients with the third type of injury, and 80%, with the fourth type of injury. Mean ICP in the group of patients with the second type of diffuse injury comprised 14.4 +/- 6.6 mmHg; with the third type of injury, 30 +/- 20.6 mmHg; with the fourth type of injuty, 37.6 +/- 14.1 mmHg. Introduction of differentiated approach to conservative or surgical treatment method application to acute diffuse brain injuries patients based on ICP monitoring data led to 13.8% reduction in mortality in the second study period compared with the first study period.

    This study evaluated the effects of voluntary ethanol consumption combined with testosterone treatment on cardiovascular function in rats. Moreover, we investigated the influence of exercise training on these effects. To this end, male rats were submitted to low-intensity training on a treadmill or kept sedentary while concurrently being treated with ethanol for 6 weeks. For voluntary ethanol intake, rats were given access to two bottles, one containing ethanol and other containing water, three 24-hour sessions per week. In the last two weeks (weeks 5 and 6), animals underwent testosterone treatment concurrently with exercise training and exposure to ethanol. Ethanol consumption was not affected by either testosterone treatment or exercise training. Also, drug treatments did not influence the treadmill performance improvement evoked by training. However, testosterone alone, but not in combination with ethanol, reduced resting heart rate. Moreover, combined treatment with testosterone and ethanol reduced the pressor response to the selective α1-adrenoceptor agonist phenylephrine. Treatment with either testosterone or ethanol alone also affected baroreflex activity and enhanced depressor response to acetylcholine, but these effects were inhibited when drugs were coadministrated. Exercise training restored most cardiovascular effects evoked by drug treatments. Furthermore, both drugs administrated alone increased pressor response to phenylephrine in trained animals. Also, drug treatments inhibited the beneficial effects of training on baroreflex function. In conclusion, the present results suggest a potential interaction between toxic effects of testosterone and ethanol on cardiovascular function. Data also indicate that exercise training is an important factor influencing the effects of these substances.

    The authors compared the effects of two ethanol doses on glucose kinetics and assessed the role of acetate as a mediator of ethanol-induced insulin resistance. Ten normal males were studied on four occasions, during which either a low or moderate ethanol, acetate, or saline dose was administered. Both ethanol doses similarly inhibited basal glucose production. The decrease in R{sub a} was matched by a comparable decrease in glucose utilization (R{sub d}), resulting in maintenance of normoglycemia. During hyperinsulinemia glucose disposal was lower in the moderate than the low-dose ethanol or saline studies. During acetate infusion, the blood acetate level was comparable with those in the ethanol studies. Acetate had no effect on glucose kinetics. In conclusion, (1) in overnight fasted subjects, ethanol does not cause hypoglycemia because its inhibitory effect on R{sub a} is counterbalanced by equal inhibition of R{sub d}; (2) basal R{sub a} and R{sub d} are maximally inhibited already by small ethanol doses, whereas inhibition of insulin-stimulated glucose disposal requires a moderate ethanol dose; and (3) acetate is not the mediator of ethanol-induced insulin resistance.

    2016-07-01

    Biocrude produced from algae by hydrothermal liquefaction was treated with near- and supercritical ethanol and ethanol-water mixtures at 210-290°C for 0.5-4h. Longer reaction times and higher temperatures better promoted esterification reactions. Dilution of the ethanol with water led to lower yields of treated biocrude and reduced ester content. The viscosity of treated biocrude was an order of magnitude lower than that of the crude bio-oil, and the treated biocrude exhibited the characteristics of a Newtonian fluid. Overall, treatment of biocrude with near- and supercritical ethanol generated a treated bio-oil with lower viscosity, more ester content, and in nearly 100wt% yield. PMID:27055767

    Full Text Available Abstract Background Poisoned patients are often treated in and discharged from pre-hospital health care settings. Studies of poisonings should therefore not only include hospitalized patients. Aims: To describe the acutely poisoned patients treated by ambulance personnel and in an outpatient clinic; compare patients transferred to a higher treatment level with those discharged without transfer; and study the one-week mortality after pre-hospital discharge. Methods A one-year multi-centre study with prospective inclusion of all acutely poisoned patients ≥ 16 years of age treated in ambulances, an outpatient clinic, and hospitals in Oslo. Results A total of 3757 health service contacts from 2997 poisoning episodes were recorded: 1860 were treated in ambulances, of which 15 died and 750 (40% were discharged without transfer; 956 were treated in outpatient clinic, of which 801 (84% were discharged without transfer; and 941 episodes were treated in hospitals. Patients discharged alive after ambulance treatment were mainly poisoned by opiates (70%, were frequently comatose (35%, had respiratory depression (37%, and many received naloxone (49%. The majority of the patients discharged from the outpatient clinic were poisoned by ethanol (55%, fewer were comatose (10%, and they rarely had respiratory depression (4%. Among the hospitalized, pharmaceutical poisonings were most common (58%, 23% were comatose, and 7% had respiratory depression. Male patients comprised 69% of the pre-hospital discharges, but only 46% of the hospitalized patients. Except for one patient, who died of a new heroin overdose two days following discharge from an ambulance, there were no deaths during the first week after the poisonings in the 90% of the pre-hospital discharged patients with known identity. Conclusion More than half of the poisoned patients treated in pre-hospital treatment settings were discharged without transfer to higher levels. These poisonings were more often

    Age-related differences in sensitivity to the acute effects of alcohol may play an important role in the increased risk for the development of alcoholism seen in teens that begin drinking at an early age. The present study evaluated the acute and protracted (hangover) effects of ethanol in adolescent (P33-P40) and adult (P100-P107) Wistar rats, using the cortical electroencephalogram (EEG). Six minutes of EEG was recorded during waking, 15 min after administration of 0, 1.5, or 3.0 g/kg ethanol, and for 3 h at 20 h post ethanol, during the rats' next sleep cycle. Significantly higher overall frontal and parietal cortical power was seen in a wide range of EEG frequencies in adolescent rats as compared to adult rats in their waking EEG. Acute administration of ethanol did not produce differences between adolescents and adults on behavioral measures of acute intoxication. However, it did produce a significantly less intense acute EEG response to ethanol in the theta frequencies in parietal cortex in the adolescents as compared to the adults. At 20 h following acute ethanol administration, during the rats' next sleep cycle, a decrease in slow-wave frequencies (1-4 Hz) was seen and the adolescent rats were found to display more reduction in the slow-wave frequencies than the adults did. The present study found that adolescent rats, as compared to adults, demonstrate low sensitivity to acute ethanol administration in the theta frequencies and more susceptibility to disruption of slow-wave sleep during hangover. These studies may lend support to the idea that these traits may contribute to increased risk for alcohol use disorders seen in adults who begin drinking in their early teenage years. PMID:24169089

    Objective: To evaluate the safety dose range of ethanolic extract from the leaves of Pericampylus glaucus(Lam.) Merr. by acute and sub-acute oral toxicity study on animal model. Methods: The acute and sub-acute toxicity study was carried out as per Organization for Economic Co-operation and Development guidelines 423 and 407. In acute toxicity study, the oral dose (300, 2 000 and 4 000 mg/kg) of tested plant extract was administered to three groups in single dose and general behavior, adverse effects and mortality were determined up to 72 h and compared to normal group. In sub-acute study, the tested crude plant extract was administered orally at doses of 600 and 1 000 mg/kg for 28 days to the two animals groups and their body weight, hematological, serum hepatic biochemical parameters were evaluated and compared to normal group by sacrificing all group animals. Results: In acute toxicity, all treated groups’ revealed neither mortality nor any significant alteration in behavior only drowsiness, sedation and lethargy were observed in two group, i.e. 2 000 and 4 000 mg/kg of the tested plant extract. In sub-acute toxicity study no change in hematological, biochemical parameter and organ body weight were observed during study compared to the normal group. The kidney function parameters [serum glutamic-oxaloacetic transaminase (aspartate transaminase), serum glutamic pyruvic transaminase (alanine transaminase)] were significantly increased following administration of tested crude plant extract (600, 1 000 mg/kg). Conclusions:The result indicates that the oral administration ofPericampylus glaucus (Lam.) Merr. extract did not produce any significant toxic effect in BALB/c mice. Hence, the extract can be utilized safely for therapeutic use in pharmaceutical formulations.

    Acute pancreatitis (AP) has a fast onset and progression, which lead to an unfavorable prognosis. Therefore, the development of novel drugs for its treatment is critical. As a homologous derivative of resveratrol, pterostilbene exerts a variety of effects including anti-inflammatory, antioxidant, and antitumor effects. This study investigated the potential of pterostilbene for treatment of severe AP (SAP) and related mechanisms. Effects of pterostilbene were evaluated in a Wistar rat model of AP. Serum levels of amylase (AMY), creatinine (Cr), and alanine aminotransferase (ALT) were quantified. Furthermore, serum levels of tumor necrosis factor (TNF)-a and interleukin (IL)-1b were quantified using enzyme-linked immunosorbent assay. Nuclear factor (NF)-kB expression in pancreatic tissues was quantified by real-time PCR and western blotting. The production of reactive oxygen species (ROS) was determined using a spectrometer, while superoxide dismutase (SOD) activity was assayed. In the AP rat model, the expression of inflammatory markers TNF-a and IL-1b, expression of NF-kB, and serum indices (AMY, Cr, and ALT) increased compared to the corresponding levels in the control group (P pancreatic tissues.

    Full Text Available Early recanalization of the occluded artery leads to better clinical outcomes in patients with acute ischemic stroke (AIS through protection of the time-sensitive penumbra. Intravenous administration of pharmacologic thrombolytic agents has been a standard treatment for AIS. To get better rates of recanalization, enhance the time window, and diminish the possibility of intracranial hemorrhage, endovascular thrombectomy was launched, with first authorization of the Merci clot retriever, a corkscrew-like apparatus, followed by approval of the Penumbra thromboaspiration system. Both devices lead to a high rate of recanalization. On the other hand, time to recanalization was on an average of 45 minutes, with most of the patients attaining only partial recanalization. More lately, retrievable stents have shown promise in decreasing the time to recanalization, and attaining a superior rate of complete clot resolution. The retrievable stent can be released within the clot to engage it within the struts of the stent, and afterwards it is taken back by pulling it under flow arrest. Neurointerventional techniques have a persistently ever-increasing and stimulating role in the management of AIS, as indicated by the advent of several important techniques. Stent retrievers have the capability to be ascertained as the most important approach to endovascular stroke treatment.

    An occupational physician reported to the French Health Products Safety Agency (Afssaps) a case of adverse effect of acute pancreatitis (AP) in a teaching nurse, after multiple demonstrations with ethanol-based hand sanitizers (EBHSs) used in a classroom with defective mechanical ventilation. It was suggested by the occupational physician that the exposure to ethanol may have produced a significant blood ethanol concentration and subsequently the AP. In order to verify if the confinement situation due to defective mechanical ventilation could increase the systemic exposure to ethanol via inhalation route, a physiologically based pharmacokinetic (PBPK) modeling was used to predict ethanol blood levels. Under the worst case scenario, the simulation by PBPK modeling showed that the maximum blood ethanol concentration which can be predicted of 5.9 mg/l is of the same order of magnitude to endogenous ethanol concentration (mean = 1.1 mg/L; median = 0.4 mg/L; range = 0-35 mg/L) in nondrinker humans (Al-Awadhi et al., 2004). The present study does not support the likelihood that EBHS leads to an increase in systemic ethanol concentration high enough to provoke an acute pancreatitis. PMID:22577377

    Gastric mucosal damage induced by ethanol is a serious medical problem. Recent evidences suggest that reactive oxygen species and inflammatory mediators play a key role in the destruction of gastric mucosa. The present study was aimed to evaluate the potential beneficial effect of MESNA (2-mercaptoethane sulfonate) against ethanol-induced gastric mucosal damage in mice. The animals were orally pretreated with vehicle or MESNA and then treated with acidified ethanol to induce gastric mucosal damage. One hour after ethanol ingestion mice were euthanized and stomach samples were collected for biochemical analysis. Macroscopic and histopathological evaluation of gastric mucosa showed that pretreatment with MESNA attenuated gastric lesions induced by ethanol. Administration of MESNA significantly increased glutathione content and superoxide dismutase and catalase activity in the gastric tissues. In addition, MESNA markedly reduced ethanol-induced lipid peroxidation, myeloperoxidase activity, tumor necrosis factor-alpha, interleukin (IL)-1β, IL-6, and monocyte chemotactic protein-1 levels. These findings suggest that the thiol-containing compound MESNA is able to decrease alcohol-induced oxidative stress and inflammation in the gastric tissue. It seems that MESNA may have a protective effect against ethanol-induced gastric mucosal damage. PMID:26967742

    Experience-produced deficits in trace conditioning and context conditioning have been useful tools for examining the role of the hippocampus in learning. It has also been suggested that learning in these tasks is especially vulnerable to neurotoxic effects of alcohol during key developmental periods such as adolescence. In five experiments we systematically examined the presence and source of age-dependent vulnerability to the memory-disrupting effects of acute ethanol in trace conditioning and contextual fear conditioning. In Experiment 1a pre-training ethanol disrupted trace conditioning more strongly in adolescent (postnatal day, PD30-35) than adult rats (PD65-75). In Experiment 1b when pre-training ethanol was accompanied by pre-test ethanol no deficit in trace conditioning was observed in adolescents, suggesting that state-dependent retrieval failure mediated ethanol's disruption of trace conditioning at this age. Experiment 2a and b examined the effect of ethanol pretreatment on context conditioning. Here, adult but not adolescent rats were impaired in conditioned freezing to context cues. Experiment 2c explored state-dependency of this effect. Pre-training ethanol continued to disrupt context conditioning in adults even when ethanol was also administered prior to test. Collectively these findings reveal clear age-dependent and task-dependent vulnerabilities in ethanol's disruptive effects on hippocampus-dependent memory. Adolescents were more disrupted by ethanol in trace conditioning than adults, and adults were more disrupted by ethanol in context conditioning than adolescents. We suggest that adolescents may be more susceptible to changes in internal state (state-dependent retrieval failure) than adults and that ethanol disrupted performance in trace and context conditioning through different mechanisms. Relevance of these findings to theories of hippocampus function is discussed.

    Ethanol produces its intoxicating effects by modifying neuronal membranes. Gangliosides stabilize neuronal membranes and promote their recovery from a variety of insults. In this experiment, the efficacy of GM1(i.p.) to reverse ethanol intoxication was evaluated in male mice trained to run on a constantly accelerating rotorod. When mice were tested 15-min following saline or ethanol GM1 pre-treatment reduced rotorod performance by 15% but was ineffective in modifying the ethanol-impaired performance. However, when mice were tested at 15, 35, 55, 75, and 95 min intervals following ethanol, GM1 pre-treatments dose-dependently reduced the efficacy and duration of ethanol in producing motor incoordination. Further, GM1 given prior to ethanol significantly prolonged the time to onset of the loss of righting reflex from 1.4 to 1.9 min, and reduced the duration of the righting-reflex loss from 94 to 77 min. This GM1 effect was seen at 24 h, but not at 48 or 72 h after its administration. The blood ethanol concentration at awakening was significantly higher in 24h GM1-treated animals than in controls suggesting that the GM1 effect was not due to an alteration in ethanol clearance. These findings support the hypothesis that GM1 promotes recovery from ethanol intoxication via a neuroprotective mechanism.

    AIM: To examine the anti-ulcerogenic and antioxidant effects of aqueous extracts of Foeniculum vulgare (FVE) on ethanol-induced gastric lesions in rats.METHODS: FVE was administered by gavage at doses of 75, 150 and 300 mg/kg, and famotidine was used at the dose of 20 mg/kg. Following a 60 min period, all the rats were given 1 mL of ethanol (80%) by gavage. One hour after the administration of ethanol, all groups were sacrificed, and the gastric ulcer index was calculated;whole blood malondialdehyde (MDA) and reduced glutathione (GSH), serum nitrate, nitrite, ascorbic acid,retinol and β-carotene levels were measured in all the groups.RESULTS: It was found that pretreatment with FVE significantly reduced ethanol-induced gastric damage.This effect of FVE was highest and statistically significant in 300 mg/kg group compared with the control (4.18 ± 2.81 vs 13.15 ± 4.08, P < 0.001). Also, pretreatment with FVE significantly reduced the MDA levels, while significantly increased GSH, nitrite, nitrate, ascorbic acid,retinol and β-carotene levels.CONCLUSION: FVE has clearly a protective effect against ethanol-induced gastric mucosal lesion, and this effect, at least in part, depends upon the reduction in lipid peroxidation and augmentation in the antioxidant activity.

    Pyranocycloartobiloxanthone A (PA), a xanthone derived from the Artocarpus obtusus Jarret, belongs to the Moraceae family which is native to the tropical forest of Malaysia. In this study, the efficacy of PA as a gastroprotective compound was examined against ethanol-induced ulcer model in rats. The rats were pretreated with PA and subsequently exposed to acute gastric lesions induced by absolute ethanol. The ulcer index, gastric juice acidity, mucus content, histological analysis, glutathione (GSH) levels, malondialdehyde level (MDA), nitric oxide (NO) and non-protein sulfhydryl group (NP-SH) contents were evaluated in vivo. The activities of PA as anti-Helicobacter pylori, cyclooxygenase-2 (COX-2) inhibitor and free radical scavenger were also investigated in vitro. The results showed that the oral administration of PA protects gastric mucosa from ethanol-induced gastric lesions. PA pretreatment significantly (p<0.05) restored the depleted GSH, NP-SH and NO levels in the gastric homogenate. Moreover, PA significantly (p<0.05) reduced the elevated MDA level due to ethanol administration. The gastroprotective effect of PA was associated with an over expression of HSP70 and suppression of Bax proteins in the ulcerated tissue. In addition, PA exhibited a potent FRAP value and significant COX-2 inhibition. It also showed a significant minimum inhibitory concentration (MIC) against H. pylori bacterium. The efficacy of PA was accomplished safely without the presence of any toxicological parameters. The results of the present study indicate that the gastroprotective effect of PA might contribute to the antioxidant and anti-inflammatory properties as well as the anti-apoptotic mechanism and antibacterial action against Helicobacter pylori.

    An overview of the different inhibitors formed by pre-treatment of lignocellulosic materials and their inhibition of ethanol production in yeast and bacteria is given. Different high temperature physical pre-treatment methods are available to render the carbohydrates in lignocellulose accessible for ethanol fermentation. The resulting hydrolyzsates contain substances inhibitory to fermentation-depending on both the raw material (biomass) and the pre-treatment applied. An overview of the inhibitory effect on ethanol production by yeast and bacteria is presented. Apart from furans formed by sugar degradation, phenol monomers from lignin degradation are important co-factors in hydrolysate inhibition, and inhibitory effects of these aromatic compounds on different ethanol producing microorganisms is reviewed. The furans and phenols generally inhibited growth and ethanol production rate (Q(EtOH)) but not the ethanol yields (Y(EtOH)) in Saccharomyces cerevisiae. Within the same phenol functional group (aldehyde, ketone, and acid) the inhibition of volumetric ethanol productivity was found to depend on the amount of methoxyl substituents and hence hydrophobicity (log P). Many pentose-utilizing strains Escherichia coli, Pichia stipititis, and Zymomonas mobilis produce ethanol in concentrated hemicellulose liquors but detoxification by overliming is needed. Thermoanaerobacter mathranii A3M3 can grow on pentoses and produce ethanol in hydrolysate without any need for detoxification. PMID:15300416

  3. Effect of Voluntary Ethanol Consumption Combined with Testosterone Treatment on Cardiovascular Function in Rats: Influence of Exercise Training.

    Sheila A Engi

    Full Text Available This study evaluated the effects of voluntary ethanol consumption combined with testosterone treatment on cardiovascular function in rats. Moreover, we investigated the influence of exercise training on these effects. To this end, male rats were submitted to low-intensity training on a treadmill or kept sedentary while concurrently being treated with ethanol for 6 weeks. For voluntary ethanol intake, rats were given access to two bottles, one containing ethanol and other containing water, three 24-hour sessions per week. In the last two weeks (weeks 5 and 6, animals underwent testosterone treatment concurrently with exercise training and exposure to ethanol. Ethanol consumption was not affected by either testosterone treatment or exercise training. Also, drug treatments did not influence the treadmill performance improvement evoked by training. However, testosterone alone, but not in combination with ethanol, reduced resting heart rate. Moreover, combined treatment with testosterone and ethanol reduced the pressor response to the selective α1-adrenoceptor agonist phenylephrine. Treatment with either testosterone or ethanol alone also affected baroreflex activity and enhanced depressor response to acetylcholine, but these effects were inhibited when drugs were coadministrated. Exercise training restored most cardiovascular effects evoked by drug treatments. Furthermore, both drugs administrated alone increased pressor response to phenylephrine in trained animals. Also, drug treatments inhibited the beneficial effects of training on baroreflex function. In conclusion, the present results suggest a potential interaction between toxic effects of testosterone and ethanol on cardiovascular function. Data also indicate that exercise training is an important factor influencing the effects of these substances.

  4. Acute ethanol exposure inhibits silencing of cerebellar Golgi cell firing induced by granule cell axon input

    Full Text Available Golgi cells (GoCs are specialized interneurons that provide inhibitory input to granule cells in the cerebellar cortex. GoCs are pacemaker neurons that spontaneously fire action potentials, triggering spontaneous inhibitory postsynaptic currents in granule cells and also contributing to the generation tonic GABAA receptor-mediated currents in granule cells. In turn, granule cell axons provide feedback glutamatergic input to GoCs. It has been shown that high frequency stimulation of granule cell axons induces a transient pause in GoC firing in a type 2-metabotropic glutamate receptor (mGluR2-dependent manner. Here, we investigated the effect ethanol on the pause of GoC firing induced by high frequency stimulation of granule cell axons. GoC electrophysiological recordings were performed in parasagittal cerebellar vermis slices from postnatal day 23 to 26 rats. Loose-patch cell-attached recordings revealed that ethanol (40 mM reversibly decreases the pause duration. An antagonist of mGluR2 reduced the pause duration but did not affect the effect of ethanol. Whole-cell voltage-clamp recordings showed that currents evoked by an mGluR2 agonist were not significantly affected by ethanol. Perforated-patch experiments in which hyperpolarizing and depolarizing currents were injected into GoCs demonstrated that there is an inverse relationship between spontaneous firing and pause duration. Slight inhibition of the Na+/K+ pump mimicked the effect of ethanol on pause duration. In conclusion, ethanol reduces the granule cell axon-mediated feedback mechanism by reducing the input responsiveness of GoCs. This would result in a transient increase of GABAA receptor-mediated inhibition of granule cells, limiting information flow at the input stage of the cerebellar cortex.

    The patient K.I., a 72-year-old male, was admitted to Nishide Hospital in July 1999 for hemodialysis treatment of end-stage chronic renal failure. At the time of his admission, an ultrasound examination of the patient's liver revealed a large mass in the S5-S8 segment. A hepatocellular carcinoma was suspected from the characteristic mosaic pattern seen with ultrasound and the elevation of alpha-fetoprotein in the serum. The patient's condition was considered to be medically inoperable, due to the patient's adaptation to hemodialysis. Furthermore, transcatheter arterial embolization was not indicated due to the patient's history of hypersensitivity to roentgen-contrast materials. An attempt to palliate the malignancy was made with a combination of local hyperthermia and percutaneous ethanol injection therapy. Magnetic resonance imaging revealed that the tumor structure had changed after 10 days of percutaneous ethanol injection therapy and that 2 months later the tumor size had decreased by about 50%. Moreover, the alpha-fetoprotein level had returned to normal by that time. In addition, this treatment did not cause any disturbance in the liver function. The patient tolerated treatment well. A combined treatment of local hyperthermia with percutaneous ethanol injection therapy appears to be useful in the management of hepatocellular carcinomas, especially in cases in which more aggressive treatment is not acceptable.

    Central cholinergic dysfunction contributes to acute spatial memory deficits produced by ethanol administration. Donepezil and rivastigmine elevate acetylcholine levels in the synaptic cleft through the inhibition of cholinesterases-enzymes involved in acetylcholine degradation. The aim of our study was to reveal whether donepezil (acetylcholinesterase inhibitor) and rivastigmine (also butyrylcholinesterase inhibitor) attenuate spatial memory impairment as induced by acute ethanol administration in the Barnes maze task (primary latency and number of errors in finding the escape box) in rats. Additionally, we compared the influence of these drugs on ethanol-disturbed memory. In the first experiment, the dose of ethanol (1.75 g/kg, i.p.) was selected that impaired spatial memory, but did not induce motor impairment. Next, we studied the influence of donepezil (1 and 3 mg/kg, i.p.), as well as rivastigmine (0.5 and 1 mg/kg, i.p.), given either before the probe trial or the reversal learning on ethanol-induced memory impairment. Our study demonstrated that these drugs, when given before the probe trial, were equally effective in attenuating ethanol-induced impairment in both test situations, whereas rivastigmine, at both doses (0.5 and 1 mg/kg, i.p.), and donepezil only at a higher dose (3 mg/kg, i.p.) given prior the reversal learning, attenuated the ethanol-induced impairment in cognitive flexibility. Thus, rivastigmine appears to exert more beneficial effect than donepezil in reversing ethanol-induced cognitive impairments-probably due to its wider spectrum of activity. In conclusion, the ethanol-induced spatial memory impairment may be attenuated by pharmacological manipulation of central cholinergic neurotransmission. PMID:27376896

    Our previous research has shown that in Long Evans rats acute prenatal exposure to a high dose of ethanol on gestational day (G) 12 produces social deficits in male offspring and elicits substantial decreases in social preference relative to controls, in late adolescents and adults regardless of sex. In order to generalize the observed detrimental effects of ethanol exposure on G12, pregnant female Sprague Dawley rats were exposed to ethanol or saline and their offspring were assessed in a modified social interaction (SI) test as early adolescents, late adolescents, or young adults. Anxiety-like behavior was also assessed in adults using the elevated plus maze (EPM) or the light/dark box (LDB) test. Age- and sex-dependent social alterations were evident in ethanol-exposed animals. Ethanol-exposed males showed deficits in social investigation at all ages and age-dependent alterations in social preference. Play fighting was not affected in males. In contrast, ethanol-exposed early adolescent females showed no changes in social interactions, whereas older females demonstrated social deficits and social indifference. In adulthood, anxiety-like behavior was decreased in males and females prenatally exposed to ethanol in the EPM, but not the LDB. These findings suggest that social alterations associated with acute exposure to ethanol on G12 are not strain-specific, although they are more pronounced in Long Evans males and Sprague Dawley females. Furthermore, given that anxiety-like behaviors were attenuated in a test-specific manner, this study indicates that early ethanol exposure can have differential effects on different forms of anxiety.

    Full Text Available Effects of the ethanol extract of Fructus Schisandrae (EtFSC on serum and liver lipid contents were investigated in mice fed with high fat/cholesterol (HFC diet for 8 or 15 days. The induction of hypercholesterolemia by HFC diet caused significant increases in serum and hepatic total cholesterol (TC levels (up to 62% and 165%, resp. and hepatic triglyceride (TG levels (up to 528% in mice. EtFSC treatment (1 or 5 g/kg/day for 7 days; from Day 1 to 7 or from Day 8 to 14, i.g. significantly decreased the hepatic TG level (down to 35% and slightly increased the hepatic index (by 8% in hypercholesterolemic mice. Whereas fenofibrate treatment (0.1 g/kg/day for 7 days, i.g. significantly lowered the hepatic TG level (by 61%, it elevated the hepatic index (by 77% in hypercholesterolemic mice. Acute toxicity test showed that EtFSC was relatively non-toxic, with an LD50 value of 35.63 ± 6.46 g/kg in mice. The results indicate that EtFSC treatment can invariably decrease hepatic TG in hypercholesterolemic mice, as assessed by both preventive and therapeutic protocols, suggesting its potential use for fatty liver treatment.

    Cavidine, a major alkaloid compound isolated from Corydalis impatiens, has various pharmacological effects but its effect on gastric ulcer has not been previously explored. The current study aimed to investigate the possible anti-ulcerogenic potential of cavidine in the model of ethanol-induced gastric ulcer. Mice received cavidine (1, 5 or 10mg/kg, ig), cimetidine (CMD, 100mg/kg, ig) or vehicle at 12h and 1h before absolute ethanol administration (0.5mL/100g), and animals were euthanized 3h after ethanol ingestion. Gross and histological gastric lesions, biochemical, immunological and Western blot parameters were taken into consideration. The results showed that ethanol administration produced apparent mucosal injuries with morphological and histological damage, whereas cavidine pre-treatment reduced the gastric injuries. Cavidine pre-treatment also ameliorated the contents of malonaldehyde (MDA) and myeloperoxidase (MPO) activity, and increased the mucosa levels of glutathione (GSH), superoxide dismutase (SOD) and prostaglandin E2 (PGE2), relative to the model group. Also cavidine was able to decrease the levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), inhibit the up-regulation of cyclo-oxygenase-2 (COX-2) expression and activation of Nuclear factor-kappa B (NF-κB) pathway. Taken together, these results indicated that cavidine exerts a gastroprotective effect against gastric ulceration, and the underlying mechanism might be associated with the stimulation of PGE2, reduction of oxidative stress, suppression of NF-κB expression and subsequent reduced COX-2 and pro-inflammatory cytokines.

    Alterations in social behavior are a hallmark of many neurodevelopmental disorders in humans. In rodents, social behavior is affected by prenatal insults. The outcomes are dependent on the timing of the insult as well as the sex and age of the animal tested. The limbic system is particularly important for social behavior, and a peak of neurogenesis within this system occurs on gestational day (G)15. Neurons appear particularly vulnerable to ethanol insult around the time they become post-mito...

    AIM: To detect the relationship between absolute ethanol injection quantity, the interval and formation of fibreboard,the curative effect in treatment of hepatocarcinoma and to evaluate the clinical application of percutaneous hepatic quantified ethanol injection (PHQEI) in treatment of hepatic carcinoma (HCC).METHODS: (1) Experimental study: Twenty-four human hepatic carcinoma SMMC-7721 xenografted nude mice were randomly divided into three groups: group A injected with quantified ethanol at short intervals (QESI), group B with quantified ethanol at long intervals (QELI) and group C with a small quantity of ethanol at long intervals (SQLI).The tumor tissues were sent for patho-histology and electron microscopic examinations. The diameters of tumors were measured with high frequency ultrasound before and after therapies and tumor growth index (TGI) was calculated.(2) Clinical study: Tumors of 122 cases of pathologically proved HCC were injected with quantified ethanol guided by ultrasound every 3-5 d 4-10 times per period of treatment. The quantity of ethanol was calculated according to the regressive equations where Y = 2.885X when the mass was ≤5 cm in diameter and Y = 1.805X when the mass was >5 cm in diameter (X is the maximal diameter of the mass with the unit cm, Y is the ethanol quantity with the unit mL). The survival rates of 1, 2, 3 and 4 years and recurrent rates in situ as well as dystopia in the liver were calculated.RESULTS: (1) Experimental study: TGI of QESI group (0.072±0.018) and QELI group (0.094±0.028) was apparently lower than that of SQLI group (1.982±0.482)(P<0.01). TGI of QESI group seemed to be lower than that of QELI group, but it was not markedly different (P>0.05) between two groups. Severe degeneration and necrosis could be seen in QESI group by patho-histology examination. Coagulative necrosis could be seen in most tumors of QESI group and there were no residual cancer cells under electronic microscope, while the residual

    Despite the promising advances in therapeutic discovery, there still is a major challenge in the development of a safe, effective, and economical intervention for managing alcohol-related liver disorders. In this study, we describe the potential use of "MAP," a standardized composition comprising three extracts from Myristica fragrans, Astragalus membranaceus, and Poria cocos, in ameliorating alcohol-induced acute liver toxicity. Ethanol-induced acute hepatotoxicity as an animal model of binge drinking was utilized. Mice received oral doses of MAP at 300 mg/kg for four consecutive days. Mice were orally gavaged with 50% ethanol in 12 mL/kg dosing volume following the third dose of MAP every 12 h thereafter for a total of three doses. Hepatic functional tests from serum collected at T12, and hepatic glutathione (GSH), superoxide dismutases (SODs), and triglyceride from liver homogenates were evaluated. Histopathology analysis and alcoholic steatohepatitis (ASH) scoring were also determined. Excessive increases of serum alanine aminotransferase and aspartate aminotransferase were significantly inhibited at 46.3% and 43.6%, respectively, when mice were treated with MAP. MAP replenished the depleted SOD by more than 60%, while causing significant stimulation of GSH productions. MAP showed statistically significant reduction in ballooning degeneration, vascular steatosis, cytoplasmic or nuclear condensation, and shrinkage, as well as inflammations when compared to vehicle-treated alcohol-induced liver toxicity model. Mice treated with MAP showed statistically significant reduction in ASH scoring when compared to vehicle control. Therefore, the composition MAP could be potentially utilized as an effective hepatic-detoxifying agent for the protection of liver damage caused by alcohol consumptions. PMID:27355692

  2. Induction of brain CYP2E1 by chronic ethanol treatment and related oxidative stress in hippocampus, cerebellum, and brainstem

    International Nuclear Information System (INIS)

    Ethanol is one of the most commonly abused substances, and oxidative stress is an important causative factor in ethanol-induced neurotoxicity. Cytochrome P450 2E1 (CYP2E1) is involved in ethanol metabolism in the brain. This study investigates the role of brain CYP2E1 in the susceptibility of certain brain regions to ethanol neurotoxicity. Male Wistar rats were intragastrically treated with ethanol (3.0 g/kg, 30 days). CYP2E1 protein, mRNA expression, and catalytic activity in various brain regions were respectively assessed by immunoblotting, quantitative quantum dot immunohistochemistry, real-time RT-PCR, and LC–MS. The generation of reactive oxygen species (ROS) was analyzed using a laser confocal scanning microscope. The hippocampus, cerebellum, and brainstem were selectively damaged after ethanol treatment, indicated by both lactate dehydrogenase (LDH) activity and histopathological analysis. Ethanol markedly increased the levels of CYP2E1 protein, mRNA expression, and activity in the hippocampus and cerebellum. CYP2E1 protein and activity were significantly increased by ethanol in the brainstem, with no change in mRNA expression. ROS levels induced by ethanol paralleled the enhanced CYP2E1 proteins in the hippocampus, granular layer and white matter of cerebellum as well as brainstem. Brain CYP2E1 activity was positively correlated with the damage to the hippocampus, cerebellum, and brainstem. These results suggest that the selective sensitivity of brain regions to ethanol neurodegeneration may be attributed to the regional and cellular-specific induction of CYP2E1 by ethanol. The inhibition of CYP2E1 levels may attenuate ethanol-induced oxidative stress via ROS generation.

    . Both the individual plant extracts and the mixed extracts of 5 plants exhibited weak to moderate antibacterial activity against four G-ve bacteria. Despite Ozoroa insignis being toxic to mice at doses above 1000 mg/kg body wt, the other plant extracts and the combined extract of the 5 plants were tolerated by mice up to 5000 mg/kg body wt. The brine shrimp test results showed the same pattern of toxicity with Ozoroa insignis being the most toxic (LC50 = 10.63 μg/ml. Phytochemical tests showed that the combined extract of the five plants contained tannins, saponins, steroids, cardiac glycosides, flavonoids and terpenoids. Flavonoids, tannins and terpenoids are known to have antioxidant activity. Conclusion The combined extract of the five plants exhibited a dose-dependent protective activity in the rat ethanol-HCl gastric ulcer model. The extracts also exhibited weak antibacterial activity against four Gram negative bacteria and low acute toxicity in mice and brine shrimps. Although the results support claims by traditional healers who use a decoction of the five plants for treatment of peptic ulcers, more models of gastric ulceration and proper animal toxicity studies are needed to validate possible clinical use of the polyherbal extract. It is also evident that the doses of the crude extracts showing protection of the gastric mucosa are too large for realistic translation to direct clinical application, but further studies using bioassay guided fractionation are important to either identify more practical fractions or active compound/s.

    Background A number of methods have been used in the treatment of symptomatic and aggressive vertebral hemangioma, but none of them is optimal. Vertebral hemangioma treated with cement vertebroplasty or ethanol injection alone showed relatively good results despite their limitations.Methods Between February 2002 and May 2004, twelve patients with vertebral hemangioma were subjected to combined cement vertebroplasty and ethanol injection, five of them were men and seven women, and aged from 26 to 54 years (mean, 41 years). The following levels of the spine were involved: T9: 1, T10: 3, T12: 2, L1: 1, L2: 2, L3:2 and L4: 1.The clinical results and radiographic records of the patients were assessed after 2 years and 5 months of follow-up.Results The average score of back pain significantly decreased from 6.5 before operation to 1.7 one month after operation. No severe complications occurred during and after operation. During the period of follow-up, symptoms were not deteriorated. At the end of follow-up, neither radiographic sign of aggressive destruction nor collapse of the involved vertebra was observed. Significant improvement in the 12 patients was demonstrated on 7 of 8 SF-36 Health Scale except for mental health.Conclusions Cement vertebroplasty combined with ethanol injection as a safe and effective technique is an alternative to the treatment of patients with vertebral hemangioma.

    @@atients with Acute Coronary Syndrome (ACS)are a clinical continuum-with patients presenting with unstable angina on one end, with patients with ST elevation myocardial infarction (STEMI) at the other end of the spectrum. In between are those with non- ST elevation myocardial infarction (NSTEMI) The pathophysiology is similar in these patients, namely isruption and fissuring of an atheromatous plaque,leading to enhanced platelet activation and local vasohyperactivity, with reduced flow and thrombus formation. While medical experts have reached consensus in the management of STEMI patients (thrombolysis nd / or percutaneous coronary intervention), optimalmanagement of patients with UA/NSTEMI remainsunclear.

    International Nuclear Information System (INIS)

    Introduction: Traumatic luxation of the knee is an infrequent pathology with low number of reported cases. That implies a true challenge for the orthopedic surgeon due to its great of presentation. Objective: Establish a scheme of surgical management for this complex injury. Methodology: Observational study with different kinds of cases of patients from Universitario Del Valle Hospital and from the Imbanaco Medical Center. These surgeries occurred from December of 1999 to February of the 2003. Patients: 16. Age average: 31 years old. Age group: 13 to 64 years. Sex: 14 male and 2 female. Luxation Types: 15 closed and 1 exposed. Procedures: Correction of the extra-capsular structures and reintegration of the crossed ligaments in cases of avulsion using an acute management approach. In the two last patients, it was performed a simultaneous reconstruction of the crossed posterior and anterior with an auto-graft followed by patients monitoring from 12 to 50 months. The most common luxation type was KDIII L according to anatomical classification. A patient with vascular injury, two with external popliteo ciatic nerve injury and one broken patellar tendon, the results were evaluated according to the scale of Lysholm, IKDC and For Special Surgery. Conclusions: The acute management of the extra-articular structures gives the best results; therefore, if the surgeon does not have enough experience, this procedure should be to left for secondary reconstruction when the patient has normal arch of mobility

    Esophageal stricture is a rare complication of paediatric cancer treatment that usually occurs after esophageal exposure to radiotherapy. We describe 4 cases of esophageal stricture during chemotherapy for acute lymphoblastic leukemia. All patients presented with refractory vomiting and were diagnosed with radiologic contrast studies. None of the patients had received radiotherapy. Esophageal candidiasis was seen in 2 patients but the remaining 2 patients had earlier systemic candidiasis. High-dose dexamethasone may predispose these children to both esophageal candidiasis and peptic esophagitis. The etiology of esophageal strictures during treatment for acute leukemia is likely to be multifactorial but systemic candidiasis may play a significant role.

    BACKGROUND:Acute intermittent porphyria (AIP) is the most common hepatic porphyria. Its clinical presentation includes severe disabling and life-threatening neurovisceral symptoms and acute psychiatric symptoms. These symptoms result from the overproduction and accumulation of porphyrin precursors, 5-aminoleuvulinic acid (ALA) and porphobilinogen (PBG). The effect of medical treatment is transient and is not effective once irreversible neurological damage has occurred. Liver transplantation (LT) replaces hepatic enzymes and can restore normal excretion of ALA and PBG and prevent acute attacks. METHOD:Two cases of LT for AIP were identiifed retro-spectively from a prospectively maintained LT database. RESULT:LT was successful with resolution of AIP in two patients who suffered from repeated acute attacks. CONCLUSION:LT can correct the underlying metabolic abnormality in AIP and improves quality of life signiifcantly.

    Full Text Available Background/Aim. According to the current principles, autonomous functional thyroid nodules are treated by surgery or by radioiodin therapy. Ultrasound guided percutaneous ethanol injection into solid tumors of the soft tissues was a starting point in attempts to treat the thyroid nodules by the same method. The aim of the study was to assess the efficiency of percutaneous injection in treating solitary, nontoxic, autonomous thyroid nodules of up to 15 mL volume. Methods. In 25 patients with solitary nontoxic autonomous thyroid nodules diagnosed by tehnetium-99m scanning as an intensive area having a complete supremacy in the paranodal tissue, an ultrasound guided percutaneous ethanol injection was applied. The procedure was carried out repeatedly once a week until the reduction in nodule size to 50% of the initial size was achieved. Results. An average size of the nodule before curing was 9.68 ± 5.01 mL. An average quantity of the injected ethanol was 9.52 ± 5.08 mL, ie 1.06 ± 0.48 mL/mg of the tissue. The regression of the nodule size in the successfully (Δvol% u = - 57.09 ± 13.75%, p < 0.001 and partly successfully cured (Δvol du = -48.45 ± 14.35%, p < 0.05 was statistically significant compared to the size before the treatment. After ceasing ethanol injection, 18 months later, a further size regression (Δvol% = -79.20 ± 9.89% compared to the initial one (p < 0.001 was noticed. Soon, after the procedure was finished, a statistically significant concentration increase of Thyroid Stimulating Hormone (TSH was noticed compared to the initial values (0.18 ± 0.16 vs 0.34 ± 0.31 mU/L, p < 0.01. According to the given criteria, in two female patients satisfactory results were not achieved, but, a year later, in one of them the nodule was not seen by repeated scintigram. The number and frequency of side effects were insignificant. Conclusion. Repeated percutaneous ethanol injections into nontoxic solitary autonomous thyroid nodules result in

    Objective: To evaluate the use of Ceiba pentandra (C. pentandra) as a glucose lowering agent and the attendant physiological changes in albino rats. Methods: Acute oral toxicity study of the extract was carried out by the administration of 10, 100, 1 000, 1 600, 2 900, and 5 000 mg/kg body weight of C. pentandra to rats in their respective groups. Twenty healthy albino rats weighing between 140 and 150 g were randomly allotted to five groups of four rats each. 100 mg/kg body weight of alloxan monohydrate was i.p. administered to rats and rats with blood glucose ? 200 mg/dL were considered diabetic. 5 mg/kg body weight of standard drug, 200 and 400 mg/kg body weight of ethanol extract of C. pentandra were orally administered to diabetic rats in their respective groups once daily for 12 days while the control groups received 0.1 mL of normal saline for the same period. The blood glucose was checked after every 4 days and the experiment was terminated on the 17th day. Results: The safe dose (LD50) of the extract was greater than 5 000 mg/kg body weight. The extract treated groups exhibited a remarkable reduction in blood glucose [(87.72 ± 7.67) mg/dL for 200 mg/kg body weight dose and (86.33 ± 4.54) mg/dL for 400 mg/kg body weight dose] competitively with the normoglycemic group [(88.71 ± 4.56) mg/dL]. The body weight of the extract and standard drug treated groups appreciated significantly (P Conclusions: Ethanol extract of C. pentandra has glucose lowering effect and can ameliorate the biochemical abnormalities associated with diabetes mellitus.

    2008-09-01

    Full Text Available Acute abdominal pain is a medical challenge for emergency physician due to the variety of possible diagnosis, lack of diagnostic and treatment standard in emergency department and the need of a rapid patient management. It is of paramount importance to quickly rule out or diagnose life threatening clinical conditions as acute myocardial infarction or aortic abdominal aneurism rupture. A few more time is allowed to confirm other diseases that lead to major complications if left untreated as acute appendicitis, testicular torsion and acute pyelonefritis. While acute abdominal pain in the elderly reflect often surgical conditions, it has a benign origin in the majority of young patients who can be generally managed as out patient, after a short clinical observation, with a diagnosis at discharge of non specific abdominal pain. The reason for the development of practical clinical pathways for patient with acute abdominal pain is to facilitate physician in differentiating patient who need hospital admission or a short intensive observation from those who can be safely discharged home.

    Fermented rice noodle production generates a large volume of starch-based wastewater. This study investigated the treatment of the fermented rice noodle wastewater using entrapped cell sequencing batch reactor (ECSBR) compared to traditional sequencing batch reactor (SBR). The yeast cells were applied because of their potential to convert reducing sugar in the wastewater to ethanol. In present study, preliminary treatment by acid hydrolysis was performed. A yeast culture, Saccharomyces cerevisiae, with calcium alginate cell entrapment was used. Optimum yeast cell loading in batch experiment and fermented rice noodle treatment performances using ECSBR and SBR systems were examined. In the first part, it was found that the cell loadings (0.6-2.7 × 108 cells/mL) did not play an important role in this study. Treatment reactions followed the second-order kinetics with the treatment efficiencies of 92-95%. In the second part, the result showed that ECSBR performed better than SBR in both treatment efficiency and system stability perspectives. ECSBR maintained glucose removal of 82.5 ± 10% for 5-cycle treatment while glucose removal by SBR declined from 96 to 40% within the 5-cycle treatment. Scanning electron microscopic images supported the treatment results. A number of yeast cells entrapped and attached onto the matrix grew in the entrapment matrix.

Methods: In 12 healthy subjects (mean age 32 ± 4 years, color Doppler imaging, short-wavelength automated perimetry, and frequency doubling perimetry was performed before and 60 minutes after oral intake of 80 mL of 40 vol% ethanol. Mean and pattern standard deviations for short-wavelength automated and frequency doubling perimetry were assessed. End diastolic velocity (EDV and peak systolic velocity (PSV were measured in the central retinal and ophthalmic arteries using color Doppler imaging. Systemic blood pressure, heart rate, intraocular pressure, and blood alcohol concentration were determined. Results: Mean PSV and EDV in the central retinal artery showed a significant increase after alcohol intake (P = 0.03 and P = 0.02, respectively. Similarly, we found a significant acceleration of blood flow velocity in the ophthalmic artery (P = 0.02 for PSV; P = 0.04 for EDV. Mean intraocular pressure decreased by 1.0 mmHg after alcohol ingestion (P = 0.01. Retinal sensitivity in short-wavelength automated perimetry did not alter, whereas in frequency doubling perimetry, the mean deviation decreased significantly. Systolic and diastolic blood pressure did not change significantly. Mean blood alcohol concentration was 0.38 ± 0.16 g/L. Conclusion: Although ethanol is known to cause peripheral vasodilation, our subjects had no significant drop in systemic blood pressure. However, a significant increase of blood flow velocity was seen in the retrobulbar vessels. Regarding visual function

    OBJECTIVE: To formulate an evidence-based treatment for one patient with acute spinal cord injury and summarize evidence for evaluating acute spinal cord injury treatment. METHODS: Studies related to the treatment for acute spinal cord injury were identified via a search of National Guideline Clearinghouse (NGC, 2000-11), the Cochrane Library (Issue 1, 2011), TRIP Database (2000-11), and PubMed (1966-2011). Treatment strategies were formulated according to three basic principles: best evidence, doctor's professional experience, and wishes of the patient. RESULTS: A total of 34 articles were selected, including 1 NGC guideline, 22 systematic reviews, and 11 randomized controlled trials. Based on our review, we arrived at the following recommendations: no clinical evidence exists definitively to recommend the use of any of neuroprotective pharmaceuticals; surgery should be undertaken early; mechanical compression devices and low-molecular weight heparin should be employed to prevent thrombosis; respiratory muscle training is beneficial for pulmonary function and quality of life; and functional electrical stimulation and acupuncture can promote functional recovery. The patient accordingly underwent surgery 6 hours after trauma without receiving any neuroprotective pharmaceuticals; low-molecular weight heparin and intermittent pneumatic compression were applied to prevent thrombosis. He also underwent respiratory muscle training daily for 8 weeks and received functional electrical stimulation for 15 minutes and acupuncture for 30 minutes every day. After follow-up for 3 months, the above therapeutic regimen was confirmed efficacious for acute spinal cord injury.CONCLUSION: Evidence-based medicine provides an individualized treatment protocol for acute spinal cord injury, which can significantly improve the therapeutic effect and prognosis.

    Free radicals and oxidative stress play a central role in gastric injuries caused by ethanol (EtOH). Antioxidant strategies to counteract EtOH toxicity are highly desirable. Norbixin (NBIX) is a carotenoid with antioxidant potential largely used in the food industry. This study evaluated the NBIX effects in a model of gastric ulcer induced by EtOH in rats. Male Wistar rats received NBIX doses of 0, 10, and 25 mg/kg by gavage 1 h after EtOH administration (0 or 75% solution, 1 mL/200 g of animal). The animals were euthanized 1 h after the NBIX administration, and their stomachs were removed for macroscopic and histopathological analyses, quantification of nonprotein sulfhydryl (NPSH) groups, lipid peroxidation (LPO) levels, and catalase (CAT) activity determination. NBIX increased LPO in gastric mucosa and caused CAT inhibition and NPSH depletion in EtOH-treated animals. Results showed that NBIX did not protect gastric tissue against EtOH damage, and this could be associated to a prooxidant effect. PMID:26353805

    Full Text Available Acute right heart syndrome is a common occurrence in intensive care units and is associated with a poor prognosis. There is lack of understanding of the involved pathophysiology, standard diagnostic protocols and treatment guidelines. Management goals include ensuring adequate right ventricle (RV filling, maximizing RV contraction and reducing RV afterload. We describe a 39-year-old female with acute decompensated right heart failure secondary to multiple causes. She was managed with inhaled nitric oxide. Her condition improved, which was evident by a decrease in her pulmonary artery systolic pressure on serial echocardiography, decreased requirement of vasopressors and successful weaning from the ventilator.

  9. The acute and preventative treatment of episodic migraine

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Episodic migraine is a common debilitating condition with significant worldwide impact. An effective management plan must include acute treatment to relieve the pain and potential disability associated with the attacks and may also include preventative treatments with an aim of decreasing attack frequency and severity in the longer term. Acute treatments must be limited to a maximum of 2-3 days a week to prevent medication overuse headache and focus on simple analgesia, non-steroidal anti-inflammatory drugs and triptans. Preventative treatments are numerous and should be considered when migraine attacks are frequent and or disabling, acute medication is failing, in special circumstances such as hemiplegic migraines or if the patient requests them. All preventative medications must be given at therapeutic doses for at least 6-8 weeks before an adequate trial can be judged ineffective. The most important factor in choosing drugs is the patient and the clinical features of their attack and treatment should be tailored to these. Relative co-morbidities will influence drug choice, as will the side effect profile and the efficacy of the drug. First line preventative drugs include ß-blockers, amitriptyline and anti-epileptic drugs such as topiramate and valproate. Drugs with lower efficacy or poorer side effect profiles include selective serotonin reuptake inhibitors (SSRIs, calcium channel antagonists, gabapentin and herbal medicines.

    2014-05-01

    Full Text Available Introduction: The impact of musculoskeletal injuries often caused loss time in sport participation. Athletes who suffered from these injuries experienced a decrease in performance and physical disability. Although a variety of treatments have been implemented to the muscle injuries, the administration of autologous blood injection is replacing the conventional rehabilitation to expedite the process of muscle recovery. Platelet-rich plasma (PRP is relatively new in muscle injury treatment and there is lack of evidence of the satisfaction of PRP treatment in muscle injuries. Purposes: The study aimed to investigate the patient satisfaction in the administration of PRP treatment and rehabilitation program for acute hamstring strain injury. Methods: Participants (competitive, semi-competitive and recreational athletes with acute hamstring strain injury (Grade II were recruited. Participants were randomly divided into either the PRP treatment or rehabilitation program. Participants were required to attend weekly follow up assessment for recovery evaluation. All the participants were required to complete a patient satisfaction questionnaire (PSQ-18 at the end of study.  The questionnaire is divided into seven sub-scales: general satisfaction, technical quality, interpersonal manner, communication, financial aspect, time spent with doctor, accessibility and convenience. Results: Participants were 22.35 ± 3.41 years. Duration from injury to first presentation in clinic ranged from two to ten days. Mean duration of recovery was 5.64 weeks. No statistically significant difference in the patient satisfaction sub-scales score between the two groups (p>0.05. Conclusion: The present study demonstrates that PRP treatment is as satisfactory as conventional rehabilitation program in managing acute hamstring strain injury. Both  modalities are correspondingly safe and have high degree of satisfaction. Given the acceptable outcomes, patients are likely to

    International Nuclear Information System (INIS)

    Inhibitory activity of Sagassum thunbergii (ST) against porcine pancreatic lipase was assessed after heat treatment, pH changes, and gamma irradiation. This analysis revealed that the ST ethanol extract exhibited high lipase inhibitory activity (37.37%) at 5 mg/mL. The ST ethanol extract was treated with heat at 60°C for 10, 30, and 60 min; 80 and 100°C for 10 and 20 min; and 121°C for 15 min, pH (2, 4, 6, 8 and 10) and γ -irradiation (3, 7 and 20 kGy). The lipase inhibitory activity of the ST ethanol extract increased in all heat treatments, especially at 121°C for 15 min (51.55%) compared with the control. With regard to pH stability, the ST ethanol extract showed no significant changes at pH 4 ~ 8, but somewhat decreased inhibitory activity was revealed at pH 2 (26.25%) and 10 (29.93%). On the other hand, the ST ethanol extract was not affected by γ -irradiation treatment conditions used in this study. These results suggest that ST has a potential role as a functional food agent.

    To assess the symptoms and signs of acute otitis media and efficiency of simple antibiotics like amoxicillin in its treatment in the primary health care setup. This is a prospective longitudinal study including 204 patients from different institutions. Patients were diagnosed as suffering from acute otitis media when presented with earache, fever, fullness and or otorrhea. Patients were divided into two equal groups on basis of the treatment they received, Group A received only symptomatic treatment while Group B were given Amoxicillin (40 mg/kg/day) for 7 days. Acute otitis media was common in children under 15 years (64.7%). Patients presented with earache (100%), aural fullness (90.68%), fever (76.47%) associated with recent onset of upper respiratory tract infections (88.23%). In group A, improvement was noticed in 28.43% in 3 days while 35.29% in 7 days. In group B, improvement was noticed in 48.03% in day 3 while 86.27% in day 7. In countries where medical care is scarce, patients lost to follow up, it is wise to treat with simple antibiotics like amoxicillin in adequate dose than to treat only symptomatically. It prevents chronicity, early hearing impairments and reduces antibiotic resistance.

    Data regarding intravenous thrombolysis in stroke patients receiving new oral anticoagulant drugs (nOAC) is sparse. In the near future, however, an increasing number of patients with atrial fibrillation will suffer recurrent stroke despite treatment with nOAC. This will cause a significant therapeutic dilemma as thrombolysis is contraindicated under such circumstances. We describe an 81-year-old patient presenting with acute ischemic stroke who was successfully treated with intravenous thrombolysis despite ongoing treatment with rivaroxaban. Our case report indicates that thrombolysis under nOAC may be safe under certain conditions and emphasizes the importance of establishing and performing specific anticoagulation tests for nOAC.

    2014-01-01

    Full Text Available Acute lymphoblastic leukemia (ALL is a cancer that immature white blood cells continuously overproduce in the bone marrow. These cells crowd out normal cells in the bone marrow bringing damage and death. Methotrexate (MTX is a drug used in the treatment of various cancer and autoimmune diseases. In particular, for the treatment of childhood acute lymphoblastic leukemia, it had significant effect. MTX competitively inhibits dihydrofolate reductase (DHFR, an enzyme that participates in the tetrahydrofolate synthesis so as to inhibit purine synthesis. In addition, its downstream metabolite methotrexate polyglutamates (MTX-PGs inhibit the thymidylate synthase (TS. Therefore, MTX can inhibit the synthesis of DNA. However, MTX has cytotoxicity and neurotoxin may cause multiple organ injury and is potentially lethal. Thus, the lower toxicity drugs are necessary to be developed. Recently, diseases treatments with Traditional Chinese Medicine (TCM as complements are getting more and more attention. In this study, we attempted to discover the compounds with drug-like potential for ALL treatment from the components in TCM. We applied virtual screen and QSAR models based on structure-based and ligand-based studies to identify the potential TCM component compounds. Our results show that the TCM compounds adenosine triphosphate, manninotriose, raffinose, and stachyose could have potential to improve the side effects of MTX for ALL treatment.

  2. Implementing guidelines for the treatment of acute otitis media.

    Science.gov (United States)

    Barenkamp, Stephen J

    2006-01-01

    The recently published Clinical Practice Guideline for the Diagnosis and Management of Acute Otitis Media represents a sincere effort by the AAP andthe AAFP to provide management guidelines for the practitioner based upon the best scientific evidence available. Despite many years of research and hundreds of clinical studies addressing various aspects of the epidemiology, clinical presentation, and treatment of acute otitis media, important questions remain unaddressed or have been addressed in a less than optimal fashion. These gaps in knowledge and deficiencies in several of the studies that formed the scientific basis for the proposed guidelines are the major reasons behind continued disagreement over certain recommendations. Until more comprehensive and careful analyses can be performed, disagreements are likely to persist. Even so, there is general agreement about most of the recommendations made in these guidelines, and these recommendations will provide a very valuable framework for the practicing physician as he or she cares for children with acute otitis media. To briefly review the major points, first is the critical importance of accurately diagnosing acute otitis media using a combination of clinical findings and observable abnormalities of the tympanic membrane and middle ear space. Particularly important is the differentiation of acute otitis media from otitis media with effusion. Second is the value of treating the pain associated with acute otitis media as a regular component of care, irrespective of any decision concerning antimicrobial treatment. Third is the option, for a select group of older patients with nonsevere disease, of withholding antimicrobial therapy for the first 48 to 72 hours, if close follow-up and active parental involvement can be guaranteed. Fourth is the recommendation that if an antimicrobial agent is used, high-dose amoxicillin (80 to 90 mg/kg/d) is the treatment of choice for most children at the time of initial presentation

    Anhydrous ethanol is a commonly used sclerotic agent for treating vascular malformations. We describe the case of a full-term 15-day-old female with a complex venolymphatic malformation involving the face and orbit. During treatment of the lesion with ethanol sclerotherapy, she suffered acute pulmonary hypertensive crisis. We discuss the pathophysiology of pulmonary hypertension related to ethanol sclerotherapy, and propose that hemolysis plays a significant role. Recommendations for evaluation, monitoring and management of this complication are also discussed.

    The hepatoxic properties of concurrent chronic oral ethanol ingestion and acute toluene inhalation were evaluated. Male rats were maintained on ethanol-containing or control liquid diets for 29 days. Animals of each group were subjected to five 20-min exposures to 10 000 ppm toluene with 30 min of room air inhalation between exposures on days 22, 24, 26, and 28 of liquid diet feeding. Some of the ethanol-fed animals were withdrawn from ethanol 14 h before exposure. Ethanol-withdrawn animals displayed an increased sensitivity to the narcotic action of toluene. Animals were sacrificed and assays performed on day 29. Stress markers (plasma corticosterone, free fatty acid, and glucose) were not affected by treatments. A modest elevation in plasma aspartate amino-transferase occurred in non-withdrawn animals receiving both ethanol and toluene. Ethanol-toluene exposure increased both relative liver weight and liver triglycerides. Toluene antagonized the hypertriglyceridemia associated with chronic ethanol ingestion. This study indicates that combined ethanol and toluene exposure has minor potential to induce acute liver injury, but results in altered deposition of hepatic triglycerides.

    In the world, hereditary angioedema (HAE) affects 1 every 50000 persons. It is characterized by highly disabling and recurrent episodes of cutaneous, abdominal and laryngeal episodes of angioedema. Asphyxia related mortality ranges from 15 to 50%. In Argentina a plasma derived C1 inhibitor concentrate (pdC1INH) has been available for the treatment of acute attacks for many decades, however, only15 (26%) out of 58 patients had received pdC1INH at least once until 2008, and only2 (3.4%) had used it regularly. After worldwide approval of the new drugs for the treatment of acute HAE attacks, adding icatibant to pdC1INH in Argentina, and after publication of the therapeutic guide for the country, 42 (82%) out of 51 patients from the original group has pdC1INH available to treat their next attack. However, 16 (18%) patients continue without access to medication and other 15 (35.7%) obtain their therapy spuriously through some other affected relative in their environment. Only 12 (28.6%) patients of the group self-treated at home. Access to treatment has greatly improved, but needs to be extended to all patients and self-treatment at home should be encouraged.

    The present-day optimal treatment of patients with acute myocardial infarction (AMI) is reviewed. The prehospital phase should be as brief as possible. Emergency observation and treatment in hospital should be initiated without delay. Schematic stages for mobilization have been discarded and free mobilization is recommended. Routine acute intervention with thrombolysis is recommended for patients in whom symptoms have been present for 6-12 hours and treatment with Aspirin is recommended. Beta-blocking agents are recommended for patients with increased risk after discharge. Treatment of ventricular and supraventricular arrhythmias, block and cardiac failure are reviewed in detail. Patients without complications should be monitored for three to five days and may be discharged after seven to ten days. Exercise ECG should be carried out at discharge to assess the working capacity, ischaemia and subjective reaction. The importance of good patient information is emphasized. Cessation of smoking, control of lipids and blood pressure are important as secondary interventions. As far as possible, outpatient control should be offered after discharge. The criteria for referral to specialized cardiological departments are established both for emergency and elective referral. Patients under the age of 70 years with high risk for repeated AMI or death after discharge (with residual ischaemia) should possibly be referred for coronary arteriography. PMID:2567543

    Full Text Available Relevance of the topic. At the present time laparoscopic appendectomy has taken its own place at the urgent surgery. In spite of this less is studied in the field of the use of the minimally invasive technologies in the cases of complicated acute appendicitis. The aim of research: to investigate the close results of the patients with acute appendicitis treatment with laparoscopic appendectomy, and to compare them with the open appendectomy results; to estimate the possibilities of laparoscopic appendectomy in the cases of complicated acute appendicitis. Materials and methods. The results of surgical treatment of 146 patients with acute appendicitis were analyzed – 59 patients in the main group, who undergone laparoscopic appendectomy, and 80 patients in the control group, who undergone open surgery. 7 patients who passed through conversion were included in the additional group. Results. The frequency of acute appendicitis complications, which were diagnosed during the operation, in the both groups had no significant distinction (50.8 % in the main group and 47.5% in the control group. But 5 patients with diffuse peritonitis and appendicular abscesses needed a conversion of laparoscopic operation into open one, because of the full sanitation necessity and technique difficulties. In the postoperative period among the patients of main group the suppuration of the wound was observed in 2 (3.4% cases, in the control group – in 10 (12.5%. The average duration of laparoscopic operation was 33.12±2.51 min, open surgery – 66.45±3.33 min. The average hospitalization period in the control group was 6.95±0.2 days and was statistically proved higher than in the main group – 4.72±0.21 days (p≤0.01. Conclusion. Laparoscopic appendectomy can be wide used in the cases of acute appendicitis, including complications, but it can be restricted in the cases of diffuse peritonitis and appendicular abscesses. This minimally invasive surgical operation

    Although intravenous administration of tissue plasminogen activator is the only proven treatment after acute ischemic stroke, there is always a concern of hemorrhagic risk after thrombolysis. Therefore, selection of patients with potential benefits in overcoming potential harms of thrombolysis is of great importance. Despite the practical issues in using magnetic resonance imaging (MRI) for acute stroke treatment, multimodal MRI can provide useful information for accurate diagnosis of stroke, evaluation of the risks and benefits of thrombolysis, and prediction of outcomes. For example, the high sensitivity and specificity of diffusion-weighted image (DWI) can help distinguish acute ischemic stroke from stroke-mimics. Additionally, the lesion mismatch between perfusion-weighted image (PWI) and DWI is thought to represent potential salvageable tissue by reperfusion therapy. However, the optimal threshold to discriminate between benign oligemic areas and the penumbra is still debatable. Signal changes of fluid-attenuated inversion recovery image within DWI lesions may be a surrogate marker for ischemic lesion age and might indicate risks of hemorrhage after thrombolysis. Clot sign on gradient echo image may reflect the nature of clot, and their location, length and morphology may provide predictive information on recanalization by reperfusion therapy. However, previous clinical trials which solely or mainly relied on perfusion-diffusion mismatch for patient selection, failed to show benefits of MRI-based thrombolysis. Therefore, understanding the clinical implication of various useful MRI findings and comprehensively incorporating those variables into therapeutic decision-making may be a more reasonable approach for expanding the indication of acute stroke thrombolysis.

    Endoscopic ultrasound is the most accurate imaging modality for the diagnosis of pancreatic cancer, and endoscopic ultrasound-guided fine needle injection has already been used for palliative interventions. Surgical resection is currently the standard treatment for pancreatic insulinoma. Medical treatment may be necessary for symptomatic patients with unresectable disease. Case reports have been published about the success of endoscopic ultrasound-guided alcoholic ablation, but it has not been reported previously in Hungarian literature. The authors present the history of an 83-year-old woman who was evaluated because of repeated hypoglycemic coma occurring during the night. Endosonographic image and laboratory findings (elevated serum insulin and chromogranin A) revealed pancreatic insulinoma. Because of severe comorbidities and high risk of surgical resection, the decision was made to ablate the insulinoma by endoscopic ultrasound-guided alcohol injection. A total of 3 mL 95% ethanol was injected into the tumor. Despite the discontinuation of the diazoxide therapy the hypoglycemic episodes disappeared. This case history confirms that endoscopic ultrasound-guided alcoholic ablation is a novel, minimal invasive alternative treatment for patients with pancreatic neuroendocrine tumors in whom surgery is not feasible.

    Objective To evaluate the therapeutic effects of percutaneous ethanol intratumoral injection(PETT) for treatment of small primary liver cancer(SPLC). Methods 240 patients with surgically or pathologically proved SPLC(<3 cm in diameter)were treated by PETT(under the guidance of B-ultrasound).Of the 240 patients ,163 had recurrent liver cancer,55 had inoperable liver cancer because of cardiac ,pulmonary ,hepat-ic and renal dydfunctions or due to the close proximity of trmor to the major vessels,and 22 refused to receive surgical resection.In 40 pa-tients who received surgical resection after PETT treatment, the resected tumors were pathologically evaluated for necrotic status and the pa-tients were followed up postoperatively.Results Postoperative1-,2- and 3-year survival rate of the 240 patients was 94.9%,84.2% and 66.3% respectively.Conclusion PETTcan be used as a non-invasive treatment for SPLC,and preoperative PETT appears to be helpful in reducing recurrence of postoperative liver cancer.

  11. Cohort study of lumbar percutaneous chemonucleolysis using ethanol gel in sciatica refractory to conservative treatment

    International Nuclear Information System (INIS)

    To investigate the efficacy of percutaneous chemonucleolysis using ethanol gel (PCEG) in alleviating radicular pain due to disc herniation after failure of conservative treatment. After failure of conservative treatment, PCEG was performed under fluoroscopic guidance in 42 patients with sciatica >4/10 on a Visual Analog Scale (VAS) for at least 6 weeks and consistent disc herniation on MRI or CT <3 months. The VAS pain score was determined at baseline, then after 1 and 3 months. We assessed the influence of patient-related factors (age, gender, pain duration) and disc herniation-related factors (level, migration pattern, disc herniation-related spinal stenosis) on outcome of PCEG. Mean pain duration was 6.7 months. Pain intensity decreased by 44 % and 62.6 % after 1 and 3 months, respectively, versus baseline (P = 0.007). A mild improvement was noted by the rheumatologist in 30/42 (71.4 %) and 36/42 (85.7 %) patients after 1 and 3 months, respectively, and in 31/42 (73.8 %) and 33/42 (78.6 %) patients by self-evaluation. Patients who failed PCEG were significantly older (49.8 vs. 37.3 years, P = 0.03). None of the other variables studied were significantly associated with pain relief. PCEG may significantly improve disc-related radicular pain refractory to conservative treatment. (orig.)

  13. Lithium-mediated protection against ethanol neurotoxicity

    2010-06-01

    Full Text Available Lithium has long been used as a mood stabilizer in the treatment of manic-depressive (bipolar disorder. Recent studies suggest that lithium has neuroprotective properties and may be useful in the treatment of acute brain injuries such as ischemia and chronic neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and amyotrophic lateral sclerosis. One of the most important neuroprotective properties of lithium is its anti-apoptotic action. Ethanol is a neuroteratogen and fetal alcohol spectrum disorders (FASD are caused by maternal ethanol exposure during pregnancy. FASD is the leading cause of mental retardation. Ethanol exposure causes neuroapoptosis in the developing brain. Ethanol-induced loss of neurons in the central nervous system underlies many of the behavioral deficits observed in FASD. Excessive alcohol consumption is also associated with Wernicke–Korsakoff syndrome and neurodegeneration in the adult brain. Recent in vivo and in vitro studies indicate that lithium is able to ameliorate ethanol-induced neuroapoptosis. Lithium is an inhibitor of glycogen synthase kinase 3 (GSK3 which has recently been identified as a mediator of ethanol neurotoxicity. Lithium’s neuroprotection may be mediated by its inhibition of GSK3. In addition, lithium also affects many other signaling proteins and pathways that regulate neuronal survival and differentiation. This review discusses the recent evidence of lithium-mediated protection against ethanol neurotoxicity and potential underlying mechanisms.

  14. Early Antibiotic Treatment in Acute Pancreatitis: More News

    Directory of Open Access Journals (Sweden)

    Jan J De Waele

    2006-07-01

    Full Text Available Early antibiotic treatment still remains a therapeutic challenge in the clinical management of acute pancreatitis and several papers have been published in this field [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]. In particular, the antibiotic of choice in preventing the infection of pancreatic necrosis seems to be imipenem [4, 9, 10, 11, 13]. Subsequently, Manes et al. [15] have reported that meropenem, an antibiotic of the same family as imipenem having considerable stability in the presence of renal dehydropeptidase-I and enhanced activity against gram-negative bacteria including Pseudomonas aeruginosa, has an efficacy similar to imipenem in terms of the incidence of pancreatic infection and extrapancreatic infections. We have previously emphasized that further studies should be carried out to specifically decide on the optimal doses of meropenem in patients with acute pancreatitis and that there is a need for studies which answer the following questions. What should the timing of early antibiotic treatment be?. What are the resistant strains selected by meropenem?. Which are the nosocomial infections and fungal superinfections resulting from this new treatment? [16, 17]. These questions are still open and the study from Manes et al. is welcome to attempt to answer some of the aforementioned questions [18]. In this study, the authors compared antibiotic prophylaxis with early antibiotic treatment started after the demonstration of pancreatic necrosis. They studied 215 consecutive patients with acute pancreatitis who were randomized to either Group A (n=108, who started antibiotic therapy (meropenem 500 mg tid at admission, or Group B (n=107, who received antibiotics after computed tomography showed necrosis. C-reactive protein was determined in all patients within 48 hours from the onset of symptoms and computed tomography was performed in both groups after at least 48 h of hospitalization; the clinical course of disease was also compared

    Treatment of schizophrenic conditions in children and adolescents comprises a range of measures such as psychopharmacotherapy, individual psychotherapy, cognitive-behavioral therapy, family therapy, psychoeducation, group therapy, therapeutic pedagogy, and creative and ergotherapy. The objectives of pharmacotherapy are three-fold: (1) elimination of acute psychotic symptoms and anxiety/agitation, (2) restoration of psychophysical harmony in the remission phase, and (3) prevention of relapses and facilitation of postpsychotic rehabilitation. Atypical antipsychotic drugs represent a major advance in the treatment of schizophrenic psychoses in childhood and adolescence. Differences in the potency of the antipsychotic effect and in undesired side effects are determined by the different receptor binding profiles of the respective substances. The use of long-term treatment with appropriate neuroleptics in combination with family therapy can significantly reduce the relapse rate. PMID:16389861

    Martinón-Torres, Federico

    2003-08-01

    This paper provides an update and critical review of available data on the treatment of acute viral bronchiolitis in previously healthy infants, with special focus on new or promising therapies. The main potential benefits of medical assistance in these patients reside in the careful monitoring of their clinical status, the maintenance of adequate hydration and oxygenation, the preservation of the airway opened and cleared of secretions and the option to perform parental education. There is no convincing evidence that any other form of therapy will reliably provide beneficial effects in infants with bronchiolitis and currently, any treatment beyond supportive care should be prescribed on a case-by-case basis with watchful appraisal of its effects. Therapies such as ribavirin, IFN, vitamin A, antibiotics, mist therapy or anticholinergics, have not demonstrated any measurable clinical effect. Several studies and meta-analyses with beta(2)-agonists and corticosteroids have failed to show any benefit of significant extent, however, physicians keep favouring their use. Presently, adrenaline has received rather consistent support from clinical trials but it is not yet widely prescribed. There are other therapeutic strategies, for instance, heliox, hypertonic saline, noninvasive ventilation, physical therapy techniques, thickened feeds or palivizumab that have shown promising potential benefits, but evidence supporting its use is still limited and further studies should be warranted. In the meantime, infants with acute viral bronchiolitis should be treated following evidence-based clinical practice guidelines, keeping the patient central in the process and being sensitive to social, cultural and familiar influences on their treatment strategy.

    2012-02-15

    Acute low back pain is one of the most common reasons for adults to see a family physician. Although most patients recover quickly with minimal treatment, proper evaluation is imperative to identify rare cases of serious underlying pathology. Certain red flags should prompt aggressive treatment or referral to a spine specialist, whereas others are less concerning. Serious red flags include significant trauma related to age (i.e., injury related to a fall from a height or motor vehicle crash in a young patient, or from a minor fall or heavy lifting in a patient with osteoporosis or possible osteoporosis), major or progressive motor or sensory deficit, new-onset bowel or bladder incontinence or urinary retention, loss of anal sphincter tone, saddle anesthesia, history of cancer metastatic to bone, and suspected spinal infection. Without clinical signs of serious pathology, diagnostic imaging and laboratory testing often are not required. Although there are numerous treatments for nonspecific acute low back pain, most have little evidence of benefit. Patient education and medications such as nonsteroidal anti-inflammatory drugs, acetaminophen, and muscle relaxants are beneficial. Bed rest should be avoided if possible. Exercises directed by a physical therapist, such as the McKenzie method and spine stabilization exercises, may decrease recurrent pain and need for health care services. Spinal manipulation and chiropractic techniques are no more effective than established medical treatments, and adding them to established treatments does not improve outcomes. No substantial benefit has been shown with oral steroids, acupuncture, massage, traction, lumbar supports, or regular exercise programs. PMID:22335313

    Full Text Available Background: Ankle injuries are among the most prevalent injuries with which a physician may encounter. In this study, the efficiency of the functional treatment was compared with the immobilization treatment in healing the acute ankle sprain. Materials and Methods: This clinical trial study was carried out on 100 male patients whose ankle sprain had been diagnosed by Yasuj Shahid Beheshti Hospital. Using block allocation randomization method and regardless of damage degree, patients were divided into two groups, functional method (1st group or immobilization with plaster (2nd group, for treatment. Several variables such as range of motion, pain intensity, inflammation, joint tenderness and returning to work after 2, 6 and 12 weeks were examined. Results: After two weeks, the average pain intensity in the first group (33.2±3.2 has been decreased compared to the second group (55±1.2, which showed a significant difference between the two groups (p<0.05. The average ankle range of motion in the first and second groups was 29.08±1.2 degrees and 20.4±2.2 degrees, respectively which had been increased significantly in the first group compared to the second group (p<0.03. Similarly, a considerable difference was observed in decreased inflammation and tenderness in the first group compared to the second one. Conclusion: In acute ankle sprains, the functional treatment is better than the immobilization treatment in alleviating pain, inflammation and improving the range of joint motion.

    2002-01-01

    Full Text Available Introduction Acute respiratory tract infections are the most common diseases of childhood. A preschool child suffers up to 5-7 infections of upper airways during a year. Upper airway infections make 80 - 90% of all respiratory infections. Etiology and treatment In 75% of all cases respiratory infections are of viral etiology, 15% of bacterial and 10% are caused by mycoplasma, rickettsiae, fungi, parasites. The treatment of respiratory infections includes antimicrobial therapy (causal, relief of symptoms (symptomatic and application of general principles of child treatment. The choice of antimicrobial drug is based on the evidence of agents and their sensitivity to antimicrobial drugs, age, patient's condition, previous treatment and possible allergic reactions to the drug. In cases where adequate specimen cannot be obtained for microbiologic tests, when these tests do not reveal the agent, or therapy must start before evidence of the agent is available, we must decide about the therapy, taking in consideration the most frequent agents, and those that would cause the most devastating clinical picture. This therapy can be modified later, according to the isolated agent and its sensitivity to the drug. Considering the incidence and importance of respiratory infections in morbidity and mortality of children, the aim of this article was to present guidelines in treatment of respiratory infections. The main point remains that the treatment should take into consideration the individual patient before all.

    This article reports the treatment of a patient suffered from acute radiation burn covering 41% TBSA, with deep partial-thickness and full-thickness injury, produced by exposure to a large-scale industrial electron accelerator. An open wound began to appear and enlarged gradually 10 weeks after the exposure. Serious wound infection with methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa, pneumonia, respiratory failure, systemic inflammatory response syndrome, nephropathy and hypoproteinemia developed successively since 3 weeks after the wound formation. Skin grafts failed to survive, resulting in enlargement of the wound. After being treated with proper measures, including parenteral nutrition, respiratory support with a ventilator, appropriate antibiotics, steroid administration for nephropathy, deep debridement for wounds followed by skin grafting, the patient was cured and discharged after undergoing 15 operations in 500 days. The clinical condition of an extensive acute radiation burn is complicated. We should pay close attention to the changes in functions of organs, and strengthen the therapeutic strategies to support the function of organs to reduce the incidence of systemic complications. The control of the infection and the timely and effective repair of the wound are still the key points of the treatment of an extensive local radiation injury.

    BACKGROUND: Dynamic rehabilitation has been suggested to be an important part of nonoperative treatment of acute Achilles tendon rupture that results in functional outcome and rerupture rates comparable with those of operative treatment. However, the optimal role of weight-bearing during early...... Rupture Score (ATRS) after one year. Secondary outcomes included heel-rise work, health-related quality of life, and the rerupture rate. Outcome assessors were blinded to the intervention. RESULTS: Thirty patients were randomized to each group; twenty-nine in the weight-bearing group and twenty-seven in...... months, the total heel-rise work performed by the injured limb relative to that by the uninjured limb was 53% in the weight-bearing group and 58% in the control group (p = 0.37). There were three reruptures in the weight-bearing group and two in the control group (p = 1.0). CONCLUSIONS: The ATRS and heel...

    Full Text Available Acute respiratory distress syndrome (ARDS is closely correlated with infection. Severe infection, e.g., sepsis and septic shock, can result in ARDS. Ventilator associated pneumonia (VAP is one of the common complications in ARDS related infection. As regards ARDS related infection, community acquired infection (CAI is different from hospital acquired infection (HAI in bacterial spectrum. The former is mainly caused by Streptococcus pneumonia, Hemophilus influenzae, Moraxelle catarrhalis, atypical pathogens and Klebsiella pneumoniae. However, HAI is mainly caused by Pseudomonas aeruginosa, Acinetobacter baumanii, methicillin-resistant Staphylococcus aureus(MRSA, and other drug-resistant bacteria. The drug-resistant bacterial infection not only makes treatment difficult, but also leads to an increase in mechanical ventilation time, length of ICU stay, mortality rate, and medical costs. The present paper has reviewed the relationship between ARDS and infection, therapeutic principles and measures of ARDS related infection, and introduced the optimal strategy of anti-infectious treatment of ARDS.

    Acute otitis media (AOM) is both a commonly diagnosed condition and a frequent indication for antibiotic use in children. Recent literature suggests that antibiotics are not needed in many children with AOM, as most cases resolve spontaneously without complication. However, a majority of AOM infections in children are still treated with antibiotics. The American Academy of Pediatrics and American Academy of Family Physicians released a guideline for treatment of AOM in children. We review the guideline as well as scientific evidence related to AOM treatment options. We support a set of evidence-based guidelines employing a delayed prescription option for antibiotic therapy in selected children. If used appropriately, these cost-effective guidelines will reduce the amount of antibiotics prescribed, increase parental satisfaction, and may lower rates of antibiotic resistance while producing similar rates of resolution of AOM.

    2002-01-01

    Full Text Available Introduction Acute respiratory tract infections are the most common childhood diseases. A preschool child suffers up to 5-7 infections of upper airways during a year. Lower airway infections make 5-20% of all respiratory infections. Etiologic factors In developed countries, 75% of pneumonias in childhood are of viral etiology, in 15% of bacterial, and in 10% of some other causative agent (mycoplasma, rickettsiae, fungi, parasites. In developing countries, bacterial pneumonias are present in much higher percentages. Treatment Treatment of respiratory infections includes antimicrobial therapy (causal, relief of symptoms (symptomatic and conduction of general principles in child treatment. The choice of antimicrobial drug is based on evidence of agents and their sensitivity to antimicrobial drugs, age, patient's condition, previous treatment and possible allergic reactions to the drug. In cases where we cannot provide adequate specimen for microbiologic testing, when these tests do not reveal the agent, or when therapy must be started before the agent is available, we must decide about the therapy, taking in consideration the most frequent agents, and those that would cause the most devastating clinical picture. This therapy can later be modified according to the isolated agent and its sensitivity to the drug. Conclusion Having in mind the incidence and importance of respiratory infections in morbidity and mortality of children the aim of this article was to show guidelines in treatment of respiratory infections in children. The main point remains that we should take in consideration the individual patient before all.

  10. Endovascular treatment of acute basilar artery occlusion: time to treatment is crucial

    International Nuclear Information System (INIS)

    Aim: To evaluate the safety and efficacy of multimodal endovascular treatment (EVT) of acute basilar artery occlusion (BAO), including bridging therapy [intravenous thrombolysis (IVT) with subsequent EVT], to compare particular EVT techniques and identify predictors of clinical outcome. Materials and methods: This retrospective, multi-centre study comprised 72 acute ischaemic stroke patients (51 males; mean age 59.1 ± 13.3 years) with radiologically confirmed BAO. The following data were collected: baseline characteristics, risk factors, pre-event antithrombotic treatment, neurological deficit at time of treatment, localization of occlusion, time to therapy, recanalization rate, post-treatment imaging findings. Thirty- and 90-day outcomes were evaluated using the modified Rankin scale with a good clinical outcome defined as 0–3 points. Results: Successful recanalization was achieved in 94.4% patients. Stepwise binary logistic regression analysis identified the presence of arterial hypertension (OR = 0.073 and OR = 0.067, respectively), National Institutes of Health Stroke Scale (NIHSS) at the time of treatment (OR = 0,829 and OR = 0.864, respectively), and time to treatment (OR = 0.556 and OR = 0.502, respectively) as significant independent predictors of 30- and 90-day clinical outcomes. Conclusion: Data from this multicentre study showed that multimodal EVT was an effective recanalization method in acute BAO. Bridging therapy shortens the time to treatment, which was identified as the only modifiable outcome predictor. - Highlights: • Various treatments are being used in recanalization of basilar artery occlusion. • Multimodal endovascular treatment is an effective recanalization method. • Time-to-treatment is the only modifiable outcome predictor. • Bridging therapy shortens time-to-treatment. • Arterial hypertension, neurologic deficit are associated with poor outcome

    Background We conducted a clinical trial to test whether prophylactic cranial irradiation could be omitted in all children with newly diagnosed acute lymphoblastic leukemia. Methods A total of 498 evaluable patients were enrolled. Treatment intensity was based on presenting features and the level of minimal residual disease after remission induction treatment. Continuous complete remission was compared between the 71 patients who previously would have received prophylactic cranial irradiation and the 56 historical controls who received it. Results The 5-year event-free and overall survival probabilities (95% confidence interval) for all 498 patients were 85.6% (79.9% to 91.3%) and 93.5% (89.8% to 97.2%), respectively. The 5-year cumulative risk of isolated central-nervous-system (CNS) relapse was 2.7% (1.1% to 4.2%), and that of any CNS relapse (isolated plus combined) was 3.9% (1.9% to 5.9%). The 71 patients had significantly better continuous complete remission than the 56 historical controls (P=0.04). All 11 patients with isolated CNS relapse remain in second remission for 0.4 to 5.5 years. CNS leukemia (CNS-3 status) or a traumatic lumbar puncture with blasts at diagnosis and a high level of minimal residual disease (≥ 1%) after 6 weeks of remission induction were significantly associated with poorer event-free survival. Risk factors for CNS relapse included the presence of the t(1;19)[TCF3-PBX1], any CNS involvement at diagnosis, and T-cell immunophenotype. Common adverse effects included allergic reactions to L-asparaginase, osteonecrosis, thrombosis, and disseminated fungal infection. Conclusions With effective risk-adjusted chemotherapy, prophylactic cranial irradiation can be safely omitted in the treatment of childhood acute lymphoblastic leukemia. PMID:19553647

    The investigation was to evaluate gastroprotective effects of ethanolic extract of M. pruriens leaves on ethanol-induced gastric mucosal injuries in rats. Forty-eight rats were divided into 8 groups: negative control, extract control, ulcer control, reference control, and four experimental groups. As a pretreatment, the negative control and the ulcer control groups were orally administered carboxymethylcellulose (CMC). The reference control was administered omeprazole orally (20 mg/kg). The ethanolic extract of M. pruriens leaves was given orally to the extract control group (500 mg/kg) and the experimental groups (62.5, 125, 250, and 500 mg/kg). After 1 h, CMC was given orally to the negative and the extract control groups. The other groups received absolute ethanol. The rats were sacrificed after 1 h. The ulcer control group exhibited significant mucosal injuries with decreased gastric wall mucus and severe damage to the gastric mucosa. The extract caused upregulation of Hsp70 protein, downregulation of Bax protein, and intense periodic acid schiff uptake of glandular portion of stomach. Gastric mucosal homogenate showed significant antioxidant properties with increase in synthesis of PGE2, while MDA was significantly decreased. The ethanolic extract of M. pruriens leaves was nontoxic (<5 g/kg) and could enhance defensive mechanisms against hemorrhagic mucosal lesions. PMID:23781513

    Full Text Available For promptly referral of a patient with acute ischemic stroke (AIS for possible thrombolysis, general practitioners (GPs need to equipped with the advanced knowledge of AIS treatment. We assessed the knowledge regarding treatment of AIS among GPs practicing in and around a quaternary care teaching hospital in south India. A total of 109 GPs who attend to medical emergencies were interviewed using a standard questionnaire. Of the 109 GPs interviewed, 54% felt that tissue plasminogen activator (tPA can be used in the treating AIS, but only 24% had chosen tPA as the best treatment option and 22% opted for other agents like citicholine or edavarone. Only 17% were aware that tPA should be given within 3 h. and 35% felt that intra-arterial thrombolysis as a treatment option.. Only 30% felt the need for good sugar control and 37% wanted aggressive lowering of blood pressure. Majority of GPs are not clear about beneficial effects of thrombolysis and are not updated regarding BP and sugar control in the setting of AIS.

    2016-05-01

    Full Text Available Peripheral neuropathy is a common complication of arsenic toxicity. Symptoms are usually mild and reversible following discontinuation of treatment. A more severe chronic sensorimotor polyneuropathy characterized by distal axonal-loss neuropathy can be seen in chronic arsenic exposure. The clinical course of arsenic neurotoxicity in patients with coexistence of thiamine deficiency is only anecdotally known but this association may potentially lead to severe consequences. We describe a case of acute irreversible axonal neuropathy in a patient with hidden thiamine deficiency who was treated with a short course of arsenic trioxide for acute promyelocytic leukemia. Thiamine replacement therapy and arsenic trioxide discontinuation were not followed by neurological recovery and severe polyneuropathy persisted at 12-month follow-up. Thiamine plasma levels should be measured in patients who are candidate to arsenic trioxide therapy. Prophylactic administration of vitamin B1 may be advisable. The appearance of polyneuropathy signs early during the administration of arsenic trioxide should prompt electrodiagnostic testing to rule out a pattern of axonal neuropathy which would need immediate discontinuation of arsenic trioxide.

    In the last 3 years 93 cases of iliofermoral trombosis were treated by surgery. We prefer the method used by Brunner, but under general anaesthesia and using a Bentley-Autotransfusion-System (ATS). The average age of our patients was 55 years (age ranged between 17 and 87 years). No lethal pulmonary embolism was observed. 2, 1 percent of the patients died following apoplex or acute heart failure. Of 67 patients who were operated on 6 months ago or more 70 percent have no further complaints, 28 percent still have some residual edema and only 2 patients have a severe postthrombotic syndrome. 50 percent of 40 control-phlebograms demonstrated patency of all veins. 20 percent had short segmentary occlusions with definite signs of recanalisation, while in 27 percent of the cases occlusions of the lower leg and thigh were found, the iliac veins being free. Only 2 postoperative phlebograms showed a complete iliofemoral venous occlusion. Our results prove, that the operative thrombectomy is a successful method, with which the main complications of the iliofemoral thrombosis-pulmonary embolisation and postthrombotic syndrome-can difinitely be reduced. Also because of better long term results, the operative therapy of acute ilofemoral thrombosis should be generally prefered instead of conservative treatment.

    Full Text Available Spinal pain syndromes come to the forefront in the structure of referral rates for medical advice and considerably reduce quality of life in this category of patients. The paper considers the role of an edematous component in the development and chronization of pain. Occurring edema gives rise to local hemo- and lymphodynamic disorders, dysregulated vascular tone, activated thrombogenesis, and increased vascular permeability, eventually leading to the excessive irritation of nociceptors, the enhancement of a pain component, and the progression of tissue swelling.Objective: to study the efficacy of L-lysine escinate in the combination treatment of acute non-specific low back pain.Patients and methods. Sixty-two patients aged 21 to 53 patients (mean age 36.4±0.9 years with acute low back pain were examined. L-lysine escinate having venotonic and anti-inflammatory activities was chosen as an agent to correct edema syndrome. The results of clinical, neurological, and manual muscular testing and assessment of the biomechanics of the vertebral column, obtained using the original soft package “Visual optic analysis” developed by the authors, were analyzed. All the patients were found to have acute non-specific low back pain or radiculopathy (entrapment syndrome and considerable changes in the biomechanics of the vertebral column. The patients were treated in accordance with the standards of medical care for spinal pain. L-lysine escinate was additionally incorporated as an antiedema drug into the therapeuticcomplex of the patients in the study group.Results and discussion. The study patient group demonstrated a more pronounced trend towards reductions in pain syndrome and local muscle edema. It was noted that L-lysine escinate was effective in treating both acute pain syndromes and exacerbations of chronic low back pain and that additional non-drug programs should be included in order to correct an impaired motor stereotype.

    2015-01-01

    Prognosis of elderly patients with acute myeloid leukemia (AML) remains poor and new treatment approaches are urgently needed. A novel nucleoside analog sapacitabine has recently emerged as a feasible agent because of its oral administration and acceptable toxicity profile. Clinical efficacy of sapacitabine, both as a single agent and in combination, has been evaluated in elderly AML patients or AML patients unfit for standard intensive chemotherapy. Response rates varied from 15 to 45% in phase II studies. Sapacitabine was overall well-tolerated with gastrointestinal and myelosuppression-related complications were the most common side effects. Unfortunately, in a phase III study sapacitabine showed no clinical superiority as compared to low-dose cytarabine (LDAC) in patients with AML. Another large phase III study comparing the combination of sapacitabine with decitabine to decitabine alone is currently ongoing and is expected to be completed by the end of 2015 or by the first half of 2016.

    1986-09-01

    Antibiotic treatment of acute otitis media (AOM) accounts for a significant number of all antibiotic prescriptions each year. In the primary care setting, initial antibiotic selection is rarely based on direct evidence, such as cultures of middle ear fluid. Initial antibiotic therapy by the primary care practitioner involves the evaluation and application of information related to prevalence of infecting organisms; in vitro antibiotic spectrum and penetration into middle ear fluid; initial cure rate, relapse and recurrence rates; and antibiotic cost, safety, and convenience. The influence of these factors on the initial antibiotic choice for AOM is reviewed. Several therapeutic dilemmas confronting the prescriber are discussed and a rational approach to initial antibiotic therapy is presented.

    AIM: To summarize the effects of laparoscopic ethanol injection and radiofrequency ablation (L-EI-RFA), thora-coscopic (T-EI-RFA) and open-surgery assisted EI-RFA (O-EI-RFA) under general anesthesia for the treatment of hepatocellular carcinoma (HCC).METHODS: Time-lag performance of RFA after ethanol injection (Time-lag PEI-RFA) was performed in all cases. The volume of coagulated necrosis and the applied energy for total and per unit volume coagulated necrosis were examined in the groups treated under general (group G) or local anesthesia (group L).RESULTS: The results showed that the total applied energy and the applied energy per unit volume of whole and marginal, coagulated necrosis were significantly larger in group G than those in the group L, resulting in a larger volume of coagulated necrosis in the group G. The rate of local tumor recurrence within one year was extremely low in group G.CONCLUSION: These results suggest that EI-RFA, under general anesthesia, may be effective for the treatment of HCC because a larger quantity of ethanol and energy could be applied during treatment under pain-free condition for the patients.

    Objective This review discussed the available data on treatment outcomes of cord blood transplantation (CBT) for acute leukemia.Data sources The data cited in this review were obtained from articles listed in Medline and Pubmed.Study selection We reviewed the articles of clinical results from various registries and institutions,as well as our experiences with CBT in children,adolescents and adults.Results This research has clearly shown that cord blood (CB) has several unique characteristics resulting in distinct advantage and disadvantages when compared to transplantation with unrelated donor bone marrow or peripheral blood stem cells.The field of CBT has advanced from investigating its safety and feasibility to addressing more specific issues such as accelerating engraftment,extending access,and examining outcomes in specific subgroups of patients.Many approaches have been investigated in the attempt to improve engraftment and survival.Variable factors have been identified,such as factors related to donor choice (human leukocyte antigen (HLA) compatibility,cell dose,and others) and transplantation (conditioning and graft-versus-host disease prophylaxis regimen).Data support that CB should be considered a reasonable option in those that do not have HLA matched sibling donor and for those in whom the time to transplant is critical.Conclusions CB is a reasonable alternative to unrelated donor bone marrow or peripheral blood progenitor cells for transplantation.Recently developed strategies aimed at improving hematopoietic recovery and reducing early transplantation-related mortality could further improve treatment outcomes of CBT for patients with acute leukemia.

  4. Intrinsic properties of larval zebrafish neurons in ethanol.

    Directory of Open Access Journals (Sweden)

    Hiromi Ikeda

    Full Text Available The behavioral effects of ethanol have been studied in multiple animal models including zebrafish. Locomotion of zebrafish larvae is resistant to high concentrations of ethanol in bath solution. This resistance has been attributed to a lower systemic concentration of ethanol in zebrafish when compared with bath solution, although the mechanism to maintain such a steep gradient is unclear. Here we examined whether the intrinsic properties of neurons play roles in this resistance. In order to minimize the contribution of metabolism and diffusional barriers, larvae were hemisected and the anterior half immersed in a range of ethanol concentrations thereby ensuring the free access of bath ethanol to the brain. The response to vibrational stimuli of three types of reticulospinal neurons: Mauthner neurons, vestibulospinal neurons, and MiD3 neurons were examined using an intracellular calcium indicator. The intracellular [Ca(2+] response in MiD3 neurons decreased in 100 mM ethanol, while Mauthner neurons and vestibulospinal neurons required >300 mM ethanol to elicit similar effects. The ethanol effect in Mauthner neurons was reversible following removal of ethanol. Interestingly, activities of MiD3 neurons displayed spontaneous recovery in 300 mM ethanol, suggestive of acute tolerance. Finally, we examined with mechanical vibration the startle response of free-swimming larvae in 300 mM ethanol. Ethanol treatment abolished long latency startle responses, suggesting a functional change in neural processing. These data support the hypothesis that individual neurons in larval zebrafish brains have distinct patterns of response to ethanol dictated by specific molecular targets.

  5. Enhancement of gamma-ray-induced mutation frequency in rice by post-treatment with chloral hydrate, methanol and their mixtures with ethanol

    International Nuclear Information System (INIS)

    An evaluation has been made of the mutagenic activity of ethanol, chlorate hydrate (CH) and methanol on rice seed. In independent treatments with ethanol, methanol, CH and four aqueous mixtures of these chemicals, chlorophyll-deficient mutants were not recovered in the M2 generation. However, in sequential treatments with gamma rays + CH, gamma rays + methanol and gamma rays + aqueous mixtures of these chemicals, significant increases in the yields of chlorophyll mutations were observed as compared to that of a 30 kR gamma ray treatment. In contrast, post-irradiation treatment with ethanol failed to provoke any increase in the frequency of chlorophyll mutants in the M2 generation. The results indicate that CH and methanol alone and mixed with ethanol can potentiate gamma ray-induced genetic lesions in rice seed. (author)

    Full Text Available We studied the effects of ethanol on the levels of norepinephrine, dopamine, serotonin (5-HT and their metabolites as well as on D1- and D2-like receptors in the rat striatum. Ethanol (2 or 4 g/kg, po was administered daily by gavage to male Wistar rats and on the 7th day, 30 min or 48 h after drug administration, the striatum was dissected for biochemical assays. Monoamine and metabolite concentrations were measured by HPLC and D1- and D2-like receptor densities were determined by binding assays. Scatchard analyses showed decreases of 30 and 43%, respectively, in D1- and D2-like receptor densities and no change in dissociation constants (Kd 48 h after the withdrawal of the dose of 4 g/kg. Ethanol, 2 g/kg, was effective only on the density of D2-like receptors but not on Kd of either receptor. Thirty minutes after the last ethanol injection (4 g/kg, decreases of D2 receptor density (45% as well as of Kd values (34% were detected. However, there was no significant effect on D1-like receptor density and a 46% decrease was observed in Kd. An increase in dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC, a decrease in norepinephrine, and no alteration in 5-HT levels were demonstrated after 48-h withdrawal of 4 g/kg ethanol. Similar effects were observed in dopamine and DOPAC levels 30 min after drug administration. No alteration in norepinephrine concentration and a decrease in 5-HT levels were seen 30 min after ethanol (4 g/kg administration. Our findings indicate the involvement of the monoaminergic system in the responses to ethanol.

  7. Radiofrequency ablation or percutaneous ethanol injection for the treatment of liver tumors

    The liver is a common location of both primary and secondary malignancies.For unresectable liver cancer,many local ablative therapies have been developed.These include e.g.,percutaneous ethanol injection (PEI),percutaneous acetic acid injection,radiofrequency ablation (RFA),cryoablation,microwave ablation,laser-induced thermotherapy,and high-intensity focused ultrasound.RFA has recently gained interest and is the most widely applied thermoablative technique.RFA allows more effective tumor control in fewer treatment sessions compared with PEI,but with a higher rate of complications.However,there are certain circumstances where PEI therapy represents a better strategy to control liver tumors than RFA,especially in situations where RFA is difficult,for example when large vessels surround the tumor.In the context of hepatocellular carcinoma (HCC),both RFA and PEI are feasible and of benefit in non-operable patients.RFA seems superior to PEI in HCC > 2 cm,and the combination of inter-ventions may be of benefit in selected patients.Liver resection is superior to RFA for patients with HCC meeting the Milan criteria,but RFA can be employed in tumors ≤ 3 cm and where there is an increased expected operative mortality.In addition,some lines of evidence indicate that RFA and PEI can be employed as a bridge to liver transplantation.The use of RFA in colorectal liver metastases is currently limited to unresectable disease and for patients unfit for surgery.The aim of this article is to summarize the current status of RFA in the management of liver tumors and compare it to the cheap and readily available technique of PEI.

    Full Text Available Abstract Background Using a rat model we have found that the bioflavonoid silymarin (SY ameliorates some of the negative consequences of in utero exposure to ethanol (EtOH. In the current study our aim was to determine if spatial working memory (SWM was impaired in offspring whose mothers were maintained on a liquid diet containing EtOH during different gestational weeks. We also determined if SWM was altered with a concomitant administration of SY with EtOH during specific gestational weeks. Methods We provided pregnant Fischer/344 rats with liquid diets containing 35% EtOH derived calories (EDC during specific weeks of the gestational period. A silymarin/phospholipid compound containing 29.8% silybin co-administered with EtOH was also administered during specific weeks of the gestational period. We tested SWM of the offspring with a radial arm maze on postnatal day (PND 60. After testing the rats were sacrificed and their brains perfused for later analysis. Results We observed SWM deficits, as well as a significantly lower brain weight in female offspring born of mothers treated with EtOH during the third week of gestation in comparison to mothers treated during either the first or second weeks of gestation. Rats from any group receiving EtOH in co-administration with SY showed no significant deficits in SWM. Conclusion EtOH treatment during the last week of gestation had the greatest impact on SWM. The addition of SY to the EtOH liquid diet appeared to ameliorate the EtOH-induced learning deficits.

  9. How assess drugs in the treatment of acute bipolar mania?

    Bipolar affective disorder is a serious mental disease associated with significant morbidity and mortality. Good-quality research available to guide treatment strategies remains insufficient, particularly with regard to manic or hypomanic episodes. A critical review of the various stages of mania might be helpful for pharmaceutical companies and investigators as a prerequisite for the clinical evaluation of potential antimanic properties of medications. The main difficulty is with a comparison between anticonvulsants, antipsychotics, and mood stabilizers such as lithium (with equal efficacy in the acute phase and the prevention of recurrent manic episodes). No consensus has been reached with regard to the treatment of bouts of acute mania in various parts of the world. Controlled clinical trials have, at last, provided irrefutable evidence of the activity of lithium, which has long been used alone, as well as that of divalproate or its derivatives and, to a lesser extent, carbamazepine. The new antipsychotic agents have more recently established their efficacy, especially aripiprazole, asenapine, quetiapine; olanzapine, risperidone, and ziprasidone (not sure where the paradox is). In Europe, haloperidol is still the reference substance used in clinical trials despite the fact that it is not officially indicated in the treatment of mania. In the USA, lithium, divalproate, or antipsychotics can be prescribed as first-line treatment. In Europe, lithium remains the first-line medication, whereas divalproate and atypical antipsychotic agents are used only as second-line therapy. Although both types of medication (antipsychotics, normothymic agents, and/or anticonvulsants) have proved to be clinically effective in the management of mania by reducing the mania scores overall, the same does not apply, however, to all symptoms of mania. Factorial approaches to mania have all shown that since there are several clinical forms of mania, several clusters of manic symptoms can

    N-type calcium channels are modulated by acute and chronic ethanol exposure in vitro at concentrations known to affect humans, but it is not known whether N-type channels are important for behavioral responses to ethanol in vivo. Here, we show that in mice lacking functional N-type calcium channels, voluntary ethanol consumption is reduced and place preference is developed only at a low dose of ethanol. The hypnotic effects of ethanol are also substantially diminished, whereas ethanol-induced...

    Full Text Available While studies in the past have focused more on treatment of the manic phase of bipolar disorder (BD, recent findings demonstrate the depressive phase to be at least as debilitating. However, in contrast to unipolar depression, depression in bipolar patients exhibits a varying response to antidepressants, raising questions regarding their efficacy and tolerability. Methods. We conducted a MEDLINE and Cochrane Collaboration Library search for papers published between 2005 and 2011 on the subject of antidepressant treatment of bipolar depression. Sixty-eight articles were included in the present review. Results. While a few studies did advocate the use of antidepressants, most well-controlled studies failed to show a robust effect of antidepressants in bipolar depression, regardless of antidepressant class or bipolar subtype. There was no significant increase in the rate of manic/hypomanic switch, especially with concurrent use of mood stabilizers. Prescribing guidelines published in recent years rely more on atypical antipsychotics, especially quetiapine, as a first-line therapy. Conclusions. Antidepressants probably have no substantial role in acute bipolar depression. However, in light of conflicting results between studies, more well-designed trials are warranted.

    Full Text Available The primary objective of this review was to update and discuss the current concepts andthe results of the treatment of acute lymphoblastic leukemia (ALL in adolescents and young adults(AYA. After a brief consideration of the epidemiologic and clinicobiologic characteristics of ALLin the AYA population, the main retrospective comparative studies stating the superiority ofpediatric over adult-based protocols were reviewed. The most important prospective studies inyoung adults using pediatric inspired or pediatric unmodified protocols were also reviewedemphasizing their feasibility at least up to the age of 40 yr and their promising results, with eventfreesurvival rates of 60-65% or greater. Results of trials from pediatric groups have shown that theunfavourable prognosis of adolescents is no more adequate. The majority of the older adolescentswith ALL can be cured with risk-adjusted and minimal residual disease-guided intensivechemotherapy, without stem cell transplantation. However, some specific subgroups, which aremore frequent in adolescents than in children (e.g., early pre-T, iAMP21, and BCR-ABL-like,deserve particular attention. In summary, the advances in treatment of ALL in adolescents havebeen translated to young adults, and that explains the significant improvement in survival of thesepatients in recent years.

  17. Clofarabine in the treatment of poor risk acute myeloid leukaemia.

    LENUS (Irish Health Repository)

    Krawczyk, Janusz

    2010-09-01

    Clofarabine is a second generation nucleoside analogue. It inhibits DNA repair and activates the mitochondrial apoptotic pathway leading to cell death. In vitro clofarabine has demonstrated synergy with daunorubicin and Ara-C and in phase II clinical trials has shown promising activity in poor risk Acute myeloid leukaemia (AML) patients. In our institution over a 24 month period 22 AML patients (11 M, 11 F) with poor risk features, deemed unsuitable for standard therapy, were treated with clofarabine, alone (eight patients) or in combination (14 patients) for up to three cycles of treatment. The median age was 67.5 years (24-76) with 16 patients > 60 years. At the time of treatment 18 patients had active AML. Four patients intolerant of standard induction received clofarabine as consolidation. The overall response rate (ORR) for the 18 patients with active AML was 61%, nine patients (50%) achieving a complete response (CR). Induction and consolidation were well tolerated with no unexpected toxicities. Predictably, all patients developed grade 4 neutropenia but the median duration was only 20 days (17-120). Induction mortality was acceptable at 17%. In conclusion, clofarabine (alone or in combination) is active in poor risk AML with an acceptable safety profile and should be considered a potential option in poor risk AML patients.

  18. Evaluation and treatment of acute low back pain.

    Kinkade, Scott

    2007-04-15

    Acute low back pain with or without sciatica usually is self-limited and has no serious underlying pathology. For most patients, reassurance, pain medications, and advice to stay active are sufficient. A more thorough evaluation is required in selected patients with "red flag" findings associated with an increased risk of cauda equina syndrome, cancer, infection, or fracture. These patients also require closer follow-up and, in some cases, urgent referral to a surgeon. In patients with nonspecific mechanical low back pain, imaging can be delayed for at least four to six weeks, which usually allows the pain to improve. There is good evidence for the effectiveness of acetaminophen, nonsteroidal anti-inflammatory drugs, skeletal muscle relaxants, heat therapy, physical therapy, and advice to stay active. Spinal manipulative therapy may provide short-term benefits compared with sham therapy but not when compared with conventional treatments. Evidence for the benefit of acupuncture is conflicting, with higher-quality trials showing no benefit. Patient education should focus on the natural history of the back pain, its overall good prognosis, and recommendations for effective treatments. PMID:17477101

    Full Text Available Judith E Karp1, Jeffrey E Lancet21Division of Hematologic Malignancies, Johns Hopkins Sidney Kimmel Comprehensive Cancer Center, Baltimore, Maryland, USA; 2H. Lee Moffitt Comprehensive Cancer Center, Tampa, Florida, USAAbstract: Farnesyltransferase inhibitors (FTIs represent a new class of signal transduction inhibitors that block the processing of cellular polypeptides that have cysteine terminal residues and, by so doing, interdict multiple pathways involved in proliferation and survival of diverse malignant cell types. Tipifarnib is an orally bioavailable, nonpeptidomimetic methylquinolone FTI that has exhibited clinical activity in patients with myeloid malignancies including elderly adults with acute myelogenous leukemia (AML who are not candidates for traditional cytotoxic chemotherapy, patients with high-risk myelodysplasia, myeloproliferative disorders, and imatinib-resistant chronic myelogenous leukemia. Because of its relatively low toxicity profile, tipifarnib provides an important alternative to traditional cytotoxic approaches for elderly patients who are not likely to tolerate or even benefit from aggressive chemotherapy. In this review, we will focus on the clinical development of tipifarnib for treatment of newly diagnosed AML, both as induction therapy for elderly adults with poor-risk AML and as maintenance therapy following achievement of first complete remission following induction and consolidation therapies for poor-risk AML. As with all other malignancies, the optimal approach is likely to lie in rational combinations of tipifarnib with cytotoxic, biologic and/or immunomodulatory agents with non-cross-resistant mechanisms of action. Gene expression profi ling has identified networks of differentially expressed genes and gene combinations capable of predicting response to single agent tipifarnib. The clinical and correlative laboratory trials in progress and under development will provide the critical foundations for

  20. Decrease in circulating tryptophan availability to the brain after acute ethanol consumption by normal volunteers: implications for alcohol-induced aggressive behaviour and depression.

    Acute ethanol consumption by fasting male volunteers decreases circulating trytophan (Trp) concentration and availability to the brain as determined by the ratio of (Trp) to the sum of its five competitors ([Trp]/[CAA]ratio). These effects of alcohol are specific to Trp, because levels of the 5 competitors are not increased. The decrease in circulating (Trp) is not associated with altered binding to albumin and may therefore be due to enhancement of hepatic Trp pyrrolase activity. It is suggested that, under these conditions brain serotonin synthesis is likely to be impaired and that, as a consequence, a possible strong depletion of brain serotonin in susceptible individuals may induce aggressive behaviour after alcohol consumption. The possible implications of these findings in the relationship between alcohol and depression are also briefly discussed.

Methods: According to the same diagnostic standard, the randomized controlled trial was conducted in several clinical centers. All 320 subjects were digitally randomized into observation group in which Houxi (SI 3) was needled and control group in which Yaotongdian (Ex-UE 7) was needled. The pain severity was scored respectively by the doctors and patients. Results: After 2-course treatment, the short-term effective rates were 89.4% and 82.5% in observation group and control group, and the long-term effective rates were 95.6% and 93.5% respectively. Ridit analysis showed a difference in the short-term effects (P<0.05) and no difference in the long-term effects (P>0.05). Conclusion: Single acupoint is quite effective for acute lumbar sprain, with better effects of Houxi (SI 3) than Yaotongdian (Ex-UE 7).

    In this work, we studied the adsorption of ethanol on three types of activated carbon, namely parent Maxsorb III and two chemically modified activated carbons (H2-Maxsorb III and KOH-H2-Maxsorb III). This investigation has been conducted on the basis of the grand canonical formalism in statistical physics and on simplified assumptions. This led to three parameter equations describing the adsorption of ethanol onto the three types of activated carbon. There was a good correlation between experimental data and results obtained by the new proposed equation. The parameters characterizing the adsorption isotherm were the number of adsorbed molecules (s) per site n, the density of the receptor sites per unit mass of the adsorbent Nm, and the energetic parameter p1/2. They were estimated for the studied systems by a non linear least square regression. The results show that the ethanol molecules were adsorbed in perpendicular (or non parallel) position to the adsorbent surface. The magnitude of the calculated adsorption energies reveals that ethanol is physisorbed onto activated carbon. Both van der Waals and hydrogen interactions were involved in the adsorption process. The calculated values of the specific surface AS, proved that the three types of activated carbon have a highly microporous surface.

    Full Text Available The objective of this study was to explore the gastroprotective properties of the aerial part of Lycium chinense Mill (LCA against ethanol-induced gastric mucosa lesions in mice models. Administration of LCA at doses of 50, 100, 200 and 400 mg/kg body weight prior to ethanol consumption dose dependently inhibited gastric ulcers. The gastric mucosal injury was analyzed by gastric juice acidity, glutathione (GSH, superoxide dismutase (SOD, malondialdehyde (MDA, myeloperoxidase (MPO activities. Furthermore, the levels of the inflammatory mediators, tumor necrosis factor-α (TNF-α, interleukin-6 (IL-6 and interleukin-1β (IL-1β in serum were also analyzed using ELISA. Pathological changes were also observed with the aid of hematoxylin-eosin (HE staining. Our results indicated that LCA significantly reduced the levels of MPO, MDA and increased SOD and GSH activities. Furthermore, LCA also significantly inhibited the levels of TNF-α, IL-6, and IL-1β in the serum of ulcerated mice in a dose dependent manner. Immunohistological analysis indicated that LCA also significantly attenuated the overexpression of nuclear factor-κB in pretreated mice models. This findings suggests Lycium chinense Mill possesses gastroprotective properties against ethanol-induced gastric injury and could be a possible therapeutic intervention in the treatment and management of gastric ulcers.

    1998-02-09

    From October 1994 to June 1997, a multidisciplinary team of scientists and engineers at Lawrence Livermore National Laboratory were funded through LDRD to develop and integrate technologies for diagnosis and treatment of acute stroke. The project was summarized in a Science and Technology Review article `Brain Attack` that appeared in June 1997 and again in the Center for Healthcare Technologies Report (UCRL-LR-124761). This article is the best overview of the project, epidemiology of stroke and technical progress. Most of the technical progress has been documented in conference papers and presentations and refereed journal articles. Additional technical publication can be expected as our remaining patent applications progress through the US Patent and Trademark Office. The purpose of this report is to provide an appropriate introduction and organization to the numerous publications so that interested readers can quickly find information. Because there is no documentation for the history of this project, this report provides a summary. It also provides the final status report for the LDRD funding.

  6. Transcatheter embolization for treatment of acute lower gastrointestinal bleeding

    International Nuclear Information System (INIS)

    Treatment of lower gastrointestinal bleeding was attempted in 13 patients by selective embolization of branches of the mesenteric arteries with Gelfoam. Bleeding was adequately controlled in 11 patients with active bleeding during the examination. One patient improved after embolization but bleeding recurred within 24 hours and in another patient the catheterization was unsuccessful. Five patients with diverticular hemorrhage were embolized in the right colic artery four times, and once in the middle colic artery. Three patients had embolization of the ileocolic artery because of hemorrhage from cecal angiodysplasia, post appendectomy, and leukemia infiltration. Three patients had the superior hemorrhoidal artery embolized because of bleeding from unspecific proctitis, infiltration of the rectum from a carcinoma of the bladder, and transendoscopic polypectomy. One patient was septic and bled from jejunal ulcers. Ischemic changes with infarction of the large bowel developed in two patients and were treated by partial semi-elective colectomy, three and four days after embolization. Four other patients developed pain and fever after embolization. Transcatheter embolization of branches of mesenteric arteries in an effective way to control acute lower gastrointestinal bleeding, but still has a significant rate of complications that must be seriously weighed against the advantages of operation.

    SUMMARY We will describe the pharmacokinetic profile, clinical efficacy and safety data of the sumatriptan iontophoretic transdermal system (Zecuity®, NuPathe Inc., PA, USA), recently approved for the acute treatment of migraine with or without aura in adults, by the US FDA. This transdermal system utilizes a low-level electrical current to deliver sumatriptan transdermally and circumvents the GI tract. Pharmacokinetic studies have shown that iontophoretic delivery of sumatriptan achieves detectable plasma concentrations 15 min after activation with a maximum mean serum concentration of 22 ng/ml. A randomized, double-blind, controlled clinical trial demonstrated minimal triptan-related side effects and superior efficacy versus placebo. The pain-free rate at 2 h postdose was 18% of patients applying the sumatriptan patch versus 9% using the placebo (p = 0.0092). This sumatriptan transdermal system may be a good choice for migraineurs with severe nausea or vomiting, those with intolerable triptan-related adverse events and/or those not responding optimally to oral medications.

    Full Text Available The present case report demonstrates a laparoscopic approach to treat interstitial cornual pregnancy in emergency. Interstitial ectopic pregnancy develops in the uterine portion of the fallopian tube which accounts for 2–4% of all ectopic pregnancies and has the potential to cause life-threatening hemorrhage at rupture. The mortality rate for a woman diagnosed with such a pregnancy is 2–2.5%. Diagnosis of interstitial pregnancy is made by ultrasound. In this case a 32 year-old woman, Gravida 0 Parity 0 Living 0 Ectopic 1, presented to the emergency obstetrical room complaining acute abdominal pain. There was a history of 10 weeks of pregnancy but no pelvic ultrasound scan was performed before the access. A transvaginal ultrasound scan immediately performed demonstrated a gestational sac with viable fetus in the right interstitial region. Moreover there was an ultrasound evidence of hemoperitoneum. She was transferred to the operating room and an emergency laparoscopy surgery was performed. The postoperative course was uneventful and the patient was discharged two days after the surgery. Interstitial pregnancies present a difficult management problem with no absolute standard of care in literature. Laparoscopic technique is under study with favorable results. For our personal point of view a treatment via laparoscopy could be performed both in elective and in emergency cases.

    Purpose Second malignant neoplasms (SMNs) after diagnosis of childhood acute lymphoblastic leukemia (ALL) are rare events. Patients and Methods We analyzed data on risk factors and outcomes of 642 children with SMNs occurring after treatment for ALL from 18 collaborative study groups between 1980 and 2007. Results Acute myeloid leukemia (AML; n = 186), myelodysplastic syndrome (MDS; n = 69), and nonmeningioma brain tumor (n = 116) were the most common types of SMNs and had the poorest outcome (5-year survival rate, 18.1% ± 2.9%, 31.1% ± 6.2%, and 18.3% ± 3.8%, respectively). Five-year survival estimates for AML were 11.2% ± 2.9% for 125 patients diagnosed before 2000 and 34.1% ± 6.3% for 61 patients diagnosed after 2000 (P < .001); 5-year survival estimates for MDS were 17.1% ± 6.4% (n = 36) and 48.2% ± 10.6% (n = 33; P = .005). Allogeneic stem-cell transplantation failed to improve outcome of secondary myeloid malignancies after adjusting for waiting time to transplantation. Five-year survival rates were above 90% for patients with meningioma, Hodgkin lymphoma, thyroid carcinoma, basal cell carcinoma, and parotid gland tumor, and 68.5% ± 6.4% for those with non-Hodgkin lymphoma. Eighty-nine percent of patients with brain tumors had received cranial irradiation. Solid tumors were associated with cyclophosphamide exposure, and myeloid malignancy was associated with topoisomerase II inhibitors and starting doses of methotrexate of at least 25 mg/m2 per week and mercaptopurine of at least 75 mg/m2 per day. Myeloid malignancies with monosomy 7/5q− were associated with high hyperdiploid ALL karyotypes, whereas 11q23/MLL-rearranged AML or MDS was associated with ALL harboring translocations of t(9;22), t(4;11), t(1;19), and t(12;21) (P = .03). Conclusion SMNs, except for brain tumors, AML, and MDS, have outcomes similar to their primary counterparts. PMID:23690411

Disability and mortality are reduced by 30% in patients treated in stroke units compared to those treated on regular wards, even if a specialized team is present on the ward. Systolic blood pressure may remain high at 200-220 mmHg in the acute phase and should not be lowered too quickly. Further guidelines for basic care include: optimal O{sub 2} delivery, blood sugar levels below 100-150 mg%, and lowering body temperature below 37.5 C using physical means or drugs. Increased intracranial pressure should be treated by raising the upper body of the patient, administration of glycerol, mannitol, and/or sorbitol, artificial respiration, and special monitoring of Tris buffer. Decompressive craniectomy may be considered in cases of ''malignant'' media stroke and expansive cerebellar infarction. Fibrinolysis is the most effective stroke treatment and is twice as effective in the treatment of stroke than myocardial infarction. Fibrinolysis may be initiated within 3 h of a stroke in the anterior circulation. If a penumbra is detectable by ''PWI-DWI mismatch MRI,'' specialized hospitals may perform fibrinolysis up to 6 h after symptom onset. In cases of stroke in the basilar artery, fibrinolysis may be performed even later after symptom onset. Intra-arterial fibrinolysis is performed in these cases using rt-PA or urokinase. Follow-up treatment of stroke patients should not only address post-stroke depression and neuropsychological deficits, but also include patient education about risk factors such as high blood pressure, diabetes mellitus, and cardiac arrhythmias.

    This study investigated the microbial diversity established in a combined system composed of a continuous stirred tank reactor (CSTR), expanded granular sludge bed (EGSB) reactor, and sequencing batch reactor (SBR) for treatment of cellulosic ethanol production wastewater. Excellent wastewater treatment performance was obtained in the combined system, which showed a high chemical oxygen demand removal efficiency of 95.8% and completely eliminated most complex organics revealed by gas chromatography-mass spectrometry (GC-MS). Denaturing gradient gel electrophoresis (DGGE) analysis revealed differences in the microbial community structures of the three reactors. Further identification of the microbial populations suggested that the presence of Lactobacillus and Prevotella in CSTR played an active role in the production of volatile fatty acids (VFAs). The most diverse microorganisms with analogous distribution patterns of different layers were observed in the EGSB reactor, and bacteria affiliated with Firmicutes, Synergistetes, and Thermotogae were associated with production of acetate and carbon dioxide/hydrogen, while all acetoclastic methanogens identified belonged to Methanosaetaceae. Overall, microorganisms associated with the ability to degrade cellulose, hemicellulose, and other biomass-derived organic carbons were observed in the combined system. The results presented herein will facilitate the development of an improved cellulosic ethanol production wastewater treatment system.

    Background Older age has historically been an adverse prognostic factor in pediatric acute myeloid leukemia (AML). The impact of age relative to that of other prognostic factors on the outcome of patients treated in recent trials is unknown. Methods Clinical outcome and causes of treatment failure of 351 patients enrolled on three consecutive protocols for childhood AML between 1991 and 2008 were analyzed according to age and protocol. Results The more recent protocol (AML02) produced improved outcomes for 10- to 21-year-old patients compared to 2 earlier studies (AML91 and 97), with 3-year rates of event-free survival (EFS), overall survival (OS) and cumulative incidence of refractory leukemia or relapse (CIR) for this group similar to those of 0- to 9-year old patients: EFS, 58.3% ± 5.4% vs. 66.6% ± 4.9%, P=.20; OS, 68.9% ± 5.1% vs. 75.1% ± 4.5%, P=.36; cumulative incidence of refractory leukemia or relapse, 21.9% ± 4.4%; vs. 25.3% ± 4.1%, P=.59. EFS and OS estimates for 10–15-year-old patients overlapped those for 16–21-year-old patients. However, the cumulative incidence of toxic death was significantly higher for 10- to 21-year-old patients compared to younger patients (13.2% ± 3.6 vs. 4.5% ± 2.0%, P=.028). Conclusion The survival rate for older children with AML has improved on our recent trial and is now similar to that of younger patients. However, deaths from toxicity remain a significant problem in the older age group. Future trials should focus on improving supportive care while striving to develop more effective antileukemic therapy. PMID:22674050

    RNA interference has tremendous yet unrealized potential to treat a wide range of illnesses. Innovative solutions are needed to protect and selectively deliver small interfering RNA (siRNA) cargo to and within a target cell to fully exploit siRNA as a therapeutic tool in vivo. Herein, we describe ammonium-functionalized carbon nanotube (fCNT)–mediated transport of siRNA selectively and with high efficiency to renal proximal tubule cells in animal models of acute kidney injury (AKI). fCNT enhanced siRNA delivery to tubule cells compared to siRNA alone and effectively knocked down the expression of several target genes, including Trp53, Mep1b, Ctr1, and EGFP. A clinically relevant cisplatin-induced murine model of AKI was used to evaluate the therapeutic potential of fCNT-targeted siRNA to effectively halt the pathogenesis of renal injury. Prophylactic treatment with a combination of fCNT/siMep1b and fCNT/siTrp53 significantly improved progression-free survival compared to controls via a mechanism that required concurrent reduction of meprin-1β and p53 expression. The fCNT/siRNA was well tolerated, and no toxicological consequences were observed in murine models. Toward clinical application of this platform, fCNTs were evaluated for the first time in nonhuman primates. The rapid and kidney-specific pharmacokinetic profile of fCNT in primates was comparable to what was observed in mice and suggests that this approach is amenable for use in humans. The nanocarbon-mediated delivery of siRNA provides a therapeutic means for the prevention of AKI to safely overcome the persistent barrier of nephrotoxicity during medical intervention.

    1999-01-01

    Acute lateral ankle ligament sprains are common in young athletes (15 to 35 years of age). Diagnostic and treatment protocols vary. Therapies range from cast immobilisation or acute surgical repair to functional rehabilitation. The lateral ligament complex includes 3 capsular ligaments: the anterior tibiofibular (ATFL), calcaneofibular (CFL) and posterior talofibular (PTFL) ligaments. Injuries typically occur during plantar flexion and inversion; the ATFL is most commonly torn. The CFL and the PTFL can also be injured and, after severe inversion, subtalar joint ligaments are also affected. Commonly, an athlete with a lateral ankle ligament sprain reports having 'rolled over' the outside of their ankle. The entire ankle and foot must be examined to ensure there are no other injuries. Clinical stability tests for ligamentous disruption include the anterior drawer test of ATFL function and inversion tilt test of both ATFL and CFL function. Radiographs may rule out treatable fractures in severe injuries or when pain or tenderness are not associated with lateral ligaments. Stress radiographs do not affect treatment. Ankle sprains are classified from grades I to III (mild, moderate or severe). Grade I and II injuries recover quickly with nonoperative management. A non-operative 'functional treatment' programme includes immediate use of RICE (rest, ice, compression, elevation), a short period of immobilisation and protection with a tape or bandage, and early range of motion, weight-bearing and neuromuscular training exercises. Proprioceptive training on a tilt board after 3 to 4 weeks helps improve balance and neuromuscular control of the ankle. Treatment for grade III injuries is more controversial. A comprehensive literature evaluation and meta-analysis showed that early functional treatment provided the fastest recovery of ankle mobility and earliest return to work and physical activity without affecting late mechanical stability. Functional treatment was complication

    Acute pancreatitis is an acute inflammation of the pancreas mostly caused by gallstones and alcohol abuse. Around 15 to 20% of patients show a severe clinical course, which is characterised by multiple organ failure and necrosis of the pancreatic parenchyma and/ or peripancreatic fat tissue. In around 30% of patients with necrotising pancreatitis, secondary infection of necrosis occurs, probably due to bacterial translocation from the patient’s own gut. Infected necrosis is an indication for ...

    Full Text Available Fruits of Pterodon pubescens Benth have been used traditionally for the treatment of rheumatism, sore throat, and respiratory disorders, and also as anti-inflammatory, analgesic, depurative, tonic, and hypoglycemic agent. The study was aimed at evaluating the anti-inflammatory activity of the hexane fraction of an ethanolic extract of P. pubescens fruits. The oil from P. pubescens fruits was extracted with ethanol and partitioned with hexane. The anti-inflammatory activity was measured with increasing doses of the hexane fraction (FHPp by using a carrageenan-induced rat model of pleurisy and a rat model of complete Freund's adjuvant-induced arthritis by using an FHPp dose of 250 mg/kg for 21 days. Treatment with an FHPp resulted in anti-inflammatory activity in both models. The results of biochemical, hematological, and histological analyses indicated a significant decrease in glucose, cholesterol, and triglycerides levels (18.32%, 34.20%, and 41.70%, resp. and reduction in the numbers of total leukocytes and mononuclear cells. The FHPp dose of 1000 mg/kg induced no changes in behavioral parameters, and no animal died. The results of this study extend the findings of previous reports that have shown that administration of extracts and fractions obtained from species of the genus Pterodon exhibits anti-inflammatory activity and lacks toxicity.

    Full Text Available The objectives of this review were to discuss standard and investigational treatment strategies for adolescent and young adult with acute myeloid leukemia, excluding acute promyelocytic leukemia. Acute myeloid leukemia (AML in adolescent and young adult patients (AYAs may need a different type of therapy than those currently used in children and older patients. As soon as AML is diagnosed, AYA patient should be offered to participate in well-designed clinical trials. The standard treatment approach for AYAs with AML is remission induction chemotherapy with an anthracycline/cytarabine combination, followed by either consolidation chemotherapy or stem cell transplantation, depending on the ability of the patient to tolerate intensive treatment and cytogenetic features. Presently, continuing progress of novel drugs targeting specific pathways in acute leukemia may bring AML treatment into a new era.

    The effect of ethanol on membrane enzymes (Na+, K+ and Mg2+ ATPases, 5'-nucleotidase, adenylate cyclase) alcohol dehydrogenase, aldehyde dehydrogenase and superoxide dismutase were studied in nerve cells (established cell lines, primary cultures of chick and rat brain) cultured in the presence of 100 mM ethanol, and in total rat brain, following various ethanol treatments of the rats (20% ethanol as the sole liquid source, intraperitoneal injection). The results show a difference between neuronal and glial cells. Most of the observed changes in enzymatic activities returned rapidly to control values when ethanol was withdrawn from the culture medium or from the diet. Alcohol dehydrogenase was more stimulated by ethanol than aldehyde dehydrogenase; therefore acetaldehyde may be accumulated. The inhibition of superoxide dismutase activity may allow an accumulation of cytotoxic O2- radicals in nervous tissue and may explain the polymorphism of lesions brought about by alcohol intoxication.

    Full Text Available Background: Inflammation is basically a defense phenomenon but can lead to serious pathological conditions. It is treated by various agents with good to moderate success because of both considerable toxicity and side effects. There are various mediators to cause an inflammatory reaction that can contribute to the associated symptoms and tissue injury. Even though non steroidal anti-inflammatory drugs are the most commonly prescribed drugs in the world, their use as anti-inflammatory agents continues to be principally limited by their undesired side effects. Hence, the traditional medical practitioners and scientists are turning towards Indian System of Medicine (ISM. Methods: Dried powdered leaves of Leucas indica were subjected to solvent extraction by using 90 % ethanol. Based on acute oral toxicity study according to Organization for Economic Cooperation and Development (OECD guidelines No. 423, three doses of the test drug 75, 150 & 300mg/kg were selected and subjected to preclinical anti-inflammatory screening by carrageenin induced paw oedema in Wistar Albino rats. Results : Oral administration of Ethanolic Extract Of Leaves of Leucas Indica (EELLI at doses of 150 mg/kg and 300mg/kg showed significant anti-inflammatory activity 52.58% (p<0.01 and 36.87% (p<0.05 respectively compared to control. Conclusion: Even though oral administration of EELLI has shown significant anti-inflammatory activity, further studies are required to evaluate its comprehensive analysis including quantitative / semi quantitative analysis, characterize its chemical structure and assess its pharmacotherapeutic activities with exact mechanism of action as an anti-inflammatory agent.

Benth. in a ratio of 6:1 (w/w and was first recorded in “Danxi’s experiential therapy” for treating gastrointestinal disorders in the 15th century. However, the poor solubility of alkaloids from ZJP restricted the protective effect in treating gastritis and gastric ulcer. The aim of the study was to investigate the protective mechanism of mucoadhesive microspheres loaded with alkaloids from C. chinensis Franch. and E. rutaecarpa (Juss. Benth. on ethanol-induced acute gastric mucosal injury in rats. Surface morphology, particle size, drug loading, encapsulation efficiency, in vitro drug release, mucoadhesiveness, and fluorescent imaging of the microspheres in gastrointestinal tract were studied. The results showed that the mucoadhesive microspheres loaded with alkaloids could sustain the release of drugs beyond 12 hours and had gastric mucoadhesive property with 82.63% retention rate in vitro. The fluorescence tracer indicated high retention of mucoadhesive microspheres within 12 hours in vivo. The mucoadhesive microspheres loaded with alkaloids could reduce the gastric injury by decreasing the mucosal lesion index, increasing the percentage of inhibition and increasing the amount of mucus in the gastric mucosa in an ethanol-induced gastric mucosal injury rat model. Moreover, the

    Full Text Available Background: There are varieties of treatment modalities to treat dorsal wrist ganglion cysts. But none of these has been the standard. So, we designed this study to compare among different treatment modalities. Objective: To compare the effects of aspiration alone, aspiration plus methylprednisone injection and aspiration plus ethanol injection into the dorsal wrist ganglions. Materials and Methods: This prospective study was performed in Dhaka Medical College Hospital, Dhaka from March 2010 to May 2011. Sixty six patients with dorsal wrist ganglions were treated in three groups –– aspiration alone in 24 patients (Group A, aspiration plus methylprednisolone injection into the cyst in 20 patients (Group B and aspiration plus ethanol injection, then reaspiration of the ethanol from the cyst after 3–5 minutes, in 22 patients (Group C. Elastic compression bandage was applied in all patients and recommended for 3 weeks. Follow-up was done at 1, 3, 6 and 12 months and conclusive assessment was done during final visit. Results: The success rate in Group A was seen in 9 patients (37.5%, in Group B in 11 (55% and in Group C in 14 (63.5% patients. The most frequent side-effect was pain during ethanol injection which was relieved by reaspiration of cyst. Conclusion: Injection of ethanol into the dorsal wrist ganglion was associated with higher success rate compared to aspiration and methylprednisolone injection. Further studies with larger sample size should be performed to assess the effect of ethanol injection in this disease.

    2015-10-01

    Full Text Available Autophagy is an intracellular pathway by which lysosomes degrade and recycle long-lived proteins and cellular organelles. The effects of ethanol on autophagy are complex but recent studies have shown that autophagy serves a protective function against ethanol-induced liver injury. Autophagy was found to also be protective against CYP2E1-dependent toxicity in vitro in HepG2 cells which express CYP2E1 and in vivo in an acute alcohol/CYPE1-dependent liver injury model. The goal of the current report was to extend the previous in vitro and acute in vivo experiments to a chronic ethanol model to evaluate whether autophagy is also protective against CYP2E1-dependent liver injury in a chronic ethanol-fed mouse model. Wild type (WT, CYP2E1 knockout (KO or CYP2E1 humanized transgenic knockin (KI, mice were fed an ethanol liquid diet or control dextrose diet for four weeks. In the last week, some mice received either saline or 3-methyladenine (3-MA, an inhibitor of autophagy, or rapamycin, which stimulates autophagy. Inhibition of autophagy by 3-MA potentiated the ethanol-induced increases in serum transaminase and triglyceride levels in the WT and KI mice but not KO mice, while rapamycin prevented the ethanol liver injury. Treatment with 3-MA enhanced the ethanol-induced fat accumulation in WT mice and caused necrosis in the KI mice; little or no effect was found in the ethanol-fed KO mice or any of the dextrose-fed mice. 3-MA treatment further lowered the ethanol-decrease in hepatic GSH levels and further increased formation of TBARS in WT and KI mice, whereas rapamycin blunted these effects of ethanol. Neither 3-MA nor rapamycin treatment affected CYP2E1 catalytic activity or content or the induction CYP2E1 by ethanol. The 3-MA treatment decreased levels of Beclin-1 and Atg 7 but increased levels of p62 in the ethanol-fed WT and KI mice whereas rapamycin had the opposite effects, validating inhibition and stimulation of autophagy, respectively.

    2014-09-01

    Full Text Available Objectives: The gastric ulcer is a common disorder of the stomach and duodenum. The basic physiopathology of a gastric ulcer results from an imbalance between some endogenous aggressive and cytoprotective factors. This study examined whether Ganoderma lucidum pharmacopuncture (GLP would provide protection against acute gastric ulcers in rats. Methods: Sprague-Dawley rats were divided randomly into 4 groups of 8 rats each: normal, control, normal saline (NP and GLP groups. The experimental acute gastric ulcer was induced by using an EtOH/HCl solution and the normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated once with injections of saline and GLP, respectively. Two local acupoints were used: CV12 (中脘 which is the alarm point of the Stomach Meridian, and ST36 (足三里, which is the sea point of the Stomach Meridian. The stomachs from the rats in each group were collected and analyzed for gross appearance and histology. Also, immunohistochemistry staining for BAX, Bcl-2 and TGF-β1 was performed. Results: Histological observations of the gastric lesions in the control group showed comparatively extensive damage of the gastric mucosa and necrotic lesions had penetrated deeply into the mucosa. The lesions were long, hemorrhagic, and confined to the glandular portions. The lesions were measured microscopically by using the clear depth of penetration into the gastric mucosal surface. The length and the width of the ulcer were measured and the inhibition percentage was calculated. Wound healing of the acute gastric ulcer was promoted by using GLP, and significant alterations of indices in gastric mucosa were observed. Such protection was shown by gross appearance, histology and immunohistochemistry staining for BAX, Bcl-2 and TGF-β1. Conclusion: These results suggest that GLP administered at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol

    Objective To investigate the effectiveness of using continuous veno venous hemofiltration (CVVH) in the treatment of acute necrotizing pancreatitis (ANP). Methods Thirteen ANP patients were involved in this study, including 4 females and 9 males, averaging 50.6±10.8 years old. CT scans upon admission revealed 33% necrosis involving the body of the pancreas in 2 patients, 67% necrosis in 3 patients and 100% necrosis in the other 8; the CT severity score was 8.9±2.1. CVVH was maintained for at least 72 hours and the AN69 hemofilter (1.2 m2) was changed every 24 hours. The ultrafiltration rate during CVVH was 2993.9±983.0 ml/h, the blood flow rate was 250-300 ml/min, and the substitute fluid was infused in a pre-diluted manner. Low molecular weight heparin was used as anticoagulant. Results CVVH was well tolerated in all the patients. Bloody abdominal cavity drainage fluid was observed in 2 patients, but no other side-effects related with CVVH were observed. Two patients died of systemic fungal infections and another died of intracranial fungi infection, resulting in an ICU mortality of 23.1%. Ten of the patients survived in the ICU, but one of them died for other reasons unrelated to the SAP before discharge. The APACHE Ⅱ score before CVVH was 15.2±6.5, but decreased significantly to 8.1±5.3, 7.5±4.9 and 8.0±5.2 at the 24th, 48th and 72nd hour after CVVH, respectively (P<0.01). Serum concentration of IL-1β and TNFα decreased to the trough at the 6th hour after a new hemofilter was used and increased slowly to pre-CVVH levels 12 hours later. After CVVH had ceased, the serum levels of two cytokines increased to their peaks at the 120th hour and decreased eventually at the 144th hour. The sieving coefficient (SC) of IL-1β and TNFα was 0.33±0.11 and 0.16±0.08. Conclusion CVVH offered therapeutic options for ANP and was well tolerated resulting in clearance of IL-1β and TNFα; CVVH at early stages of SAP may contribute to the improvement of outcome.

    Full Text Available Background Diarrhea is one of the major causes of morbidity and mortality in children throughout the world, mostly due to rotavirus infection. In daily practice, we routinely use the World Health Organization Five steps for managing acute diarrhea.This practice has shown great success in diarrhea management, but concerns remain on reducing the duration of diarrhea to prevent complications. Synbiotics can reduce the severity of diarrhea. However, there has been limited data on synbiotic therapy for treating acute rotavirus diarrhea in children. Objective To compare the durations of acute rotavirus diarrhea treated with synbiotics vs. placebo. Methods This study was a randomized, double-blind, clinical trial, performed at the Pediatric Gastrohepatology Division, Sanglah and Wangaya Hospitals in Denpasar. Subjects were children aged 6 to 59 months with acute rotavirus diarrhea. Rotavirus was diagnosed by immune chromatography assay. The synbiotic group received probiotic comprised of Lactobacillus sp., Streptococcus sp., Bifidobacterium sp. (total viable count 1.00x109 CFU per dose, and prebiotic consisted of 990.00 mg fructooligosacharide (FOS. The placebo consisted of lactose monohydrate packaged similarly as the synbiotics. Subjects orally ingested 1 pack per day for 5 days. Results Seventy children with acute rotavirus diarrhea was involved in this study. The median duration of diarrhea in the synbiotic group was 50.0 (SE 1.1; 95%CI 47.9 to 52.1 hours, while that of the placebo group was 63.0 (SE 5.9; 95%CI 51.4 to 74.6 hours. Based on Kaplan-Meier survival analysis, the duration of diarrhea in the synbiotic group was significantly shorter than that of the placebo group (log-rank test P <0.0001. Conclusion In children with acute rotaviral diarrhea, synbiotic reduces the duration of diarrhea compared to placebo. [Paediatr Indones. 2015;55:74-8.].

    Patients who are diagnosed with acute lung injury/acute respiratory distress syndrome (ALI/ARDS) usually have ventilation-perfusion mismatch, severe decrease in lung capacity, and gas exchange abnormalities. Health care work-ers have implemented various strategies in an attempt to compensate for these pathological alterations. By rotating patients with ALI/ARDS between the supine and prone position, it is possible to achieve a significant improvement in PaO2/FiO2, decrease shunting and therefore improve oxy-genation without use of expensive, invasive and experimen-tal procedures.

    Full Text Available A series of new 2-(ethylthiobenzohydrazone derivatives (1-6 were prepared and characterised by IR, 1H NMR, and 13C NMR spectroscopy and mass spectrometry. The newly prepared compounds were screened for their in vitro antioxidant activities using free radical scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH and ferric reducing antioxidant power (FRAP assays. Among them, most powerful antioxidant, compound 1 has been selected in order to illustrate anti-ulcer effect on ethanol-induced gastric mucosal lesions in rats. Four groups of Sprague Dawley rats were respectively treated with 10% Tween 20 as ulcer control group, 20 mg/kg omeprazole as reference group, 50 mg/kg and 100 mg/kg compound 1 as experimental animals. Macroscopically, ulcer control group showed extensive hemorrhagic lesions of gastric mucosa compared with omeprazole or compound 1. Rats pre-treated with compound 1 showed increased in gastric pH and gastric mucus. Histologically, ulcer control group showed severe damage to gastric mucosa with edema and leucocytes infiltration of submucosal layer. In immunohistochemical analysis, rats which were pre-treated with compound 1 showed up-regulation of HSP70 and down-regulation of Bax proteins. In conclusion, the gastroprotective effect of compound 1 may be due to its antioxidant activity, and/or due to up-regulation of HSP70 and down-regulation of Bax protein in stained tissue section.

    Full Text Available Michael Lichtenberg1, Matthias Käunicke1, Birgit Hailer1,21Cardiovascular Clinic, Vascular Center, Katholisches Klinikum Essen, Germany; 2University of Witten/Herdecke, GermanyAbstract: Acute and subacute ischemia of the legs in acute and subacute femoropopliteal bypass occlusion is a dramatic situation that endangers the survival of the limbs, depending on the severity of the ischemia. Different therapy options like percutaneous mechanical thrombectomy procedures, which include rotational thrombectomy, have become available in recent years, in addition to local lysis and surgical thrombectomy. Surgical thrombectomy using the Fogarty catheter technique, in particular, shows an increased incidence of perioperative complications but only small technical success rates in randomized trials. On the other hand, local lysis is associated with increased costs due to resource-consuming measures, such as intensive monitoring and repeat angiographies, in addition to bleeding complications. In the past, further development of the Straub Rotarex® system as an endovascular therapy option has demonstrated good success leading to amputation-free survival in multiple studies. At the same time, a low rate of complications with use has been documented. Most examinations have been conducted in the thigh. To date, there are little investigational data on its use in acutely and subacutely occluded femoropopliteal bypasses. In this paper, the current study-based significance of the Rotarex system for this indication is analyzed based on the existing literature and the authors' own experiences with 22 patients.Keywords: acute limb ischemia, femoropopliteal bypass, local lysis, rotational thrombectomy

    Calcium pantothenate (CaP), calcium 4'-phosphopantothenate (CaPP), pantethine, panthenol, sulfopantetheine and CoA decrease acute toxicity of acetaldehyde in mice. All studied compounds diminish duration of the narcotic action of ethanol--ET (3.5 g/kg intraperitoneally) in mice and rats. In the latter this effect is realized at the expense of "long sleeping" and "middle sleeping" animals. CaP (150 mg/kg subcutaneously) and CaPP (100 mg/kg subcutaneously) prevent hypothermia and a decrease of oxygen consumption in rats induced by ET administration. Combined administration of ET, CaP and CaPP leads to a characteristic increase of acid-soluble CoA fractions in the rat liver and a relative decrease of acetyl CoA synthetase and N-acetyltransferase reactions. The antitoxic effect of preparations of pantothenic acid is not mediated by CoA-dependent reactions of detoxication, but most probably is due to intensification of ET oxidation and perhaps to its elimination from the organism.

    Background Ethanol is metabolized by a two-step process in which alcohol dehydrogenase (ADH) oxidizes ethanol to acetaldehyde, which is further oxidized to acetate by aldehyde dehydrogenase (ALDH). Although variation in ethanol metabolism in humans strongly influences the propensity to chronically abuse alcohol, few data exist on the behavioral effects of altered ethanol metabolism. Here, we used the nematode C. elegans to directly examine how changes in ethanol metabolism alter behavioral responses to alcohol during an acute exposure. Additionally, we investigated ethanol solution osmolarity as a potential explanation for contrasting published data on C. elegans ethanol sensitivity. Methods We developed a gas chromatography assay and validated a spectrophotometric method to measure internal ethanol in ethanol-exposed worms. Further, we tested the effects of mutations in ADH and ALDH genes on ethanol tissue accumulation and behavioral sensitivity to the drug. Finally, we tested the effects of ethanol solution osmolarity on behavioral responses and tissue ethanol accumulation. Results Only a small amount of exogenously applied ethanol accumulated in the tissues of C. elegans and consequently their tissue concentrations were similar to those that intoxicate humans. Independent inactivation of an ADH-encoding gene (sodh-1) or an ALDH-encoding gene (alh-6 or alh-13) increased the ethanol concentration in worms and caused hypersensitivity to the acute sedative effects of ethanol on locomotion. We also found that the sensitivity to the depressive effects of ethanol on locomotion is strongly influenced by the osmolarity of the exogenous ethanol solution. Conclusions Our results indicate that ethanol metabolism via ADH and ALDH has a statistically discernable but surprisingly minor influence on ethanol sedation and internal ethanol accumulation in worms. In contrast, the osmolarity of the medium in which ethanol is delivered to the animals has a more substantial effect on

    This invention presents a method of improving enzymatic degradation of lignocellulose, as in the production of ethanol from lignocellulosic material, through the use of ultrasonic treatment. The invention shows that ultrasonic treatment reduces cellulase requirements by 1/3 to 1/2. With the cost of enzymes being a major problem in the cost-effective production of ethanol from lignocellulosic material, this invention presents a significant improvement over presently available methods.

  17. Characterization of chemically induced ovarian carcinomas in an ethanol-preferring rat model: influence of long-term melatonin treatment.

    Directory of Open Access Journals (Sweden)

    Luiz Gustavo A Chuffa

    Full Text Available Ovarian cancer is the fourth most common cause of cancer deaths among women, and chronic alcoholism may exert co-carcinogenic effects. Because melatonin (mel has oncostatic properties, we aimed to investigate and characterize the chemical induction of ovarian tumors in a model of ethanol-preferring rats and to verify the influence of mel treatment on the overall features of these tumors. After rats were selected to receive ethanol (EtOH, they were surgically injected with 100 µg of 7,12-dimethyl-benz[a]anthracene (DMBA plus sesame oil directly under the left ovarian bursa. At 260 days old, half of the animals received i.p. injections of 200 µg mel/100 g b.w. for 60 days. Four experimental groups were established: Group C, rats bearing ovarian carcinomas (OC; Group C+EtOH, rats voluntarily consuming 10% (v/v EtOH and bearing OC; Group C+M, rats bearing OC and receiving mel; and Group C+EtOH+M, rats with OC consuming EtOH and receiving mel. Estrous cycle and nutritional parameters were evaluated, and anatomopathological analyses of the ovarian tumors were conducted. The incidence of ovarian tumors was higher in EtOH drinking animals 120 days post-DMBA administration, and mel efficiently reduced the prevalence of some aggressive tumors. Although mel promoted high EtOH consumption, it was effective in synchronizing the estrous cycle and reducing ovarian tumor mass by 20%. While rats in the C group displayed cysts containing serous fluid, C+EtOH rats showed solid tumor masses. After mel treatment, the ovaries of these rats presented as soft and mobile tissues. EtOH consumption increased the incidence of serous papillary carcinomas and sarcomas but not clear cell carcinomas. In contrast, mel reduced the incidence of sarcomas, endometrioid carcinomas and cystic teratomas. Combination of DMBA with EtOH intake potentiated the incidence of OC with malignant histologic subtypes. We concluded that mel reduces ovarian masses and the incidence of

  18. Acute cerebral infarction: pathophysiology and modern treatment concepts

    International Nuclear Information System (INIS)

    This review focuses on the pathophysiological changes in acute cerebral ischemia, with special emphasis on disturbances of the cerebral blood flow (CBF) and the associated penumbra concept. Alternatively, the model of peri-infarct depolarization is demonstrated. Metabolic and molecular changes caused by cerebral ischemia and reperfusion are discussed, namely energy failure, release of glutamate with an excitatoric burst, calcium influx in neurons, generation of free radicals, activation of different proteases, disturbances of protein synthesis, induction of gene expression and apoptosis, loss of membrane integrity, edema formation and microvascular disturbances. In summary, the pathophysiological changes after focal cerebral ischemia and reperfusion are most adequately described by a network of interacting different mechanisms of tissue alterations. The simple concept of a cascade of ischemic effect which would be easy to block seems to be less applicable. A time window of approximately 6 h for the acute stroke therapy is postulated on the base of the above mentioned pathophysiological changes. (orig./AJ)

    We report the case of a patient with narrow angles who had an attack of bilateral acute angle-closure glaucoma precipitated by dexfenfluramine, a serotoninergic drug developed for appetite suppression. Although the exact mechanism remains uncertain, the pupillary block observed in our case may be the result of the serotoninergic or indirect parasympatholytic properties of the drug on the iris sphincter muscle. Serotonergic psychoactive drugs should be prescribed cautiously in patients with known narrow angles and should be monitored by an ophthalmologist.

    1993-06-01

    We report our clinical experience with a group of 14 patients who presented with acute myocardial infarction. A holmium:YAG laser was applied to the infarct-related artery. This laser emits 250 - 600 mJ per pulse, with a pulse length of 250 microseconds and repetition rate of 5 Hz. Potential benefits of acute thrombolysis by lasers include the absence of systemic lytic state; a shortened thrombus clearing time relative to using thrombolytics; safe removal of the intracoronary thrombus and facilitation of adjunct balloon angioplasty. Potential clinical difficulties include targeting the obstructive clot and plaque, creation of debris and distal emboli and laser-tissue damage. It is conceivable that holmium:YAG laser can be a successful thrombolytic device as its wave length (2.1 microns) coincides with strong water absorption peaks. Since it is common to find an atherosclerotic plaque located under or distal to the thrombotic occlusion, this laser can also be applied for plaque ablation, and the patient presenting with acute myocardial infarction can clearly benefit from the combined function of this laser system.

    Peculiarities of clinical course, diagnosis and treatment of elderly patients for an acute pancreatitis were analyzed. There was established, that the clinical course of an acute pancreatitis is atypical with obscure symptoms. Late admittance to hospital, presence of concomitant diseases, low reactivity of the organism defense systems, morpho-functional changes in pancreatic gland complicate the early diagnosis. While the abdominal pain occurrence in the patient it is necessary always to keep in mind the diagnosis of an acute pancreatitis and not to rely on the diagnosis with which the patient was delivered to hospital. Because of presence of several concomitant diseases in a patient with an acute pancreatitis the treatment must be multimodal with multidisciplinary approach, including surgeon, anesthesiologist and therapeutist. Operative intervention is mandatory only in presence of a life-threatening complications and in insufficiency of conservative therapy. Miniinvasive technologies constitute the first-line procedures.

    The treatment of acute hematogenous osteomyelitis has evolved in recent years to a shorter parenteral treatment with an early switch to the oral route. Current publications recommend a 2- to 4-day parenteral treatment before the oral switch. We retrospectively analyzed a series of 45 children aged 1 to 11 years and treated in our department for acute osteomyelitis without severity criterion. Nineteen of 45 patients were treated by an exclusive ambulatory oral treatment by amoxicillin and clavulanic acid. Twenty six of 45 patients had a 2- to 4-day parenteral treatment before the oral switch. The minimum follow-up was 6 months. The primary endpoint was a clinical, radiographic, and biologic healing, 6 months after the beginning of the treatment. The secondary endpoints evaluated were the length of hospitalization, the total duration of treatment, and the type of antibiotic used. On the primary endpoint, we did not find any significant difference between the 2 treatments (P = 0.38). On the duration of treatment, we found a significant difference (P = 0.049) in favor of oral treatment. The ambulatory oral treatment by amoxicillin and clavulanic acid seems to be a valid alternative to the classical parenteral then oral sequence in the treatment of acute hematogenous osteomyelitis in children without severity criterion.

    Esophageal stent placement was used primarily for the treatment of malignant strictures until the development of a new generation of biomaterials allowed the production of easily removable, occlusive stents in 2001. Since then, thoracic surgeons have gained experience using esophageal stents for the treatment of acute esophageal perforation. As part of a hybrid treatment strategy, including surgical drainage of infected spaces, enteral nutrition, and aggressive supportive care, esophageal stent placement has produced results that can exceed those of traditional surgical repair. This review summarizes the evolution of esophageal stent use for acute perforation and provides evidence-based recommendations for the technique. PMID:27427525

    Clofarabine, a second-generation purine analog displaying potent inhibition of DNA synthesis and favorable pharmacologic profile, is approved for the treatment of acute lymphoblastic leukemia (ALL) after failure of at least two previous regimens in patients up to 21 years of age at diagnosis. Good neurologic tolerance, synergy with alkylating agents, management guidelines defined through pediatric ALL and adult acute myeloid leukemia, have also prompted its administration in more than 100 adults with Philadelphia chromosome-positive and negative B lineage and T lineage ALL, as single agent (40 mg/m(2)/ day for 5 days), or in combination. In a Group for Research on Adult Acute Lympho- blastic Leukemia (GRAALL) retrospective study of two regimens (clofarabine ± cyclophosphamide + / - etoposide (ENDEVOL) ± mitoxantrone ± asparaginase ± dexamethasone (VANDEVOL)), remission was achieved in 50% of 55 relapsed/refractory patients, and 17-35% could proceed to allogeneic stem cell.

However, we do not have a complete description of the mesenteric lymph proteome during acute pancreatitis. Objective The aim of this study was to define the proteomic changes in mesenteric lymph during acute pancreatitis. Setting Animal Laboratory, University of Auckland, New Zealand. Design Mesenteric lymph was collected from sixteen male Wistar rats randomised to Group 1 (n=8 with taurocholate induced acute pancreatitis and Group 2 (n=8 sham control. The lymph was subjected to proteomic analysis using iTRAQTM (Applied Biosystems, Foster City, CA, USA and liquid chromatography-tandem mass spectrometry. Results Two hundred and forty-five proteins including 35 hypothetical proteins were identified in mesenteric lymph. Eight of the 245 proteins had a significant increase in their relative abundance in acute pancreatitis conditioned mesenteric lymph, and 7 of these were pancreatic catabolic enzymes (pancreatic amylase 2, pancreatic lipase, carboxypeptidase A2, chymotrypsinogen B, carboxypeptidase B1, cationic trypsinogen, ribonuclease 1. Conclusions This is the first comprehensive description of the proteome of mesenteric lymph during acute pancreatitis and has demonstrated a significantly increased relative abundance of 7 secreted pancreatic catabolic enzymes in acute pancreatitis conditioned mesenteric lymph. This study provides a clear rationale for further research to investigate the efficacy of enteral protease inhibitors in the treatment of acute pancreatitis.

    Background: venous malformations are congenital lesions that can cause pain, decreased range of movement, compression on adjacent structures, bleeding, consumptive coagulopathy and cosmetic deformity. Sclerotherapy alone or combined with surgical excision is the accepted treatment in symptomatic malformations after failed treatment attempts with tailored compression garments. Objectives: to report our experience with percutaneous sclerotherapy of peripheral venous malformations with ethanol 96%. Patients and methods: 41 sclerotherapy sessions were performed on 21 patients, aged 4-46 years, 15 females and 6 males. Fourteen patients were treated for painful extremity lesions, while five others with face and neck lesions and two with giant chest malformations had treatment for esthetic reasons. All patients had a pre-procedure magnetic resonance imaging (MRI) study. In all patients, 96% ethanol was used as the sclerosant by direct injection using general anesthesia. A minimum of 1-year clinical follow-up was performed. Follow-up imaging studies were performed if clinically indicated. Results: 17 patients showed complete or partial symptomatic improvement after one to nine therapeutic sessions. Four patients with lower extremity lesions continue to suffer from pain and they are considered as a treatment failure. Complications were encountered in five patients, including acute pulmonary hypertension with cardiovascular collapse, pulmonary embolus, skin ulcers (two) and skin blisters.

    2015-06-01

    Zebrafish is emerging as a species of choice in alcohol-related pharmacological studies. In these studies, zebrafish are often exposed to acute ethanol treatments and their activity scored during behavioral assays. Computational modeling of zebrafish behavior is expected to positively impact these efforts by offering a predictive toolbox to plan hypothesis-driven studies, reduce the number of subjects, perform pilot trials, and refine behavioral screening. In this work, we demonstrate the use of the recently proposed jump persistent turning walker to model the turning rate dynamics of zebrafish exposed to acute ethanol administration. This modeling framework is based on a stochastic mean reverting jump process to capture the sudden and large changes in orientation of swimming zebrafish. The model is calibrated on an available experimental dataset of 40 subjects, tested at different ethanol concentrations. We demonstrate that model parameters are modulated by ethanol administration, whereby both the relaxation rate and jump frequency of the turning rate dynamics are influenced by ethanol concentration. This effort offers a first evidence for the possibility of complementing zebrafish pharmacological research with computational modeling of animal behavior.

    We present a substantial series of behavioral and imaging experiments, which demonstrate, for the first time, that increasing AMPA receptor-mediated neurotransmission via administration of potent and selective biarylsulfonamide AMPA potentiators LY404187 and LY451395 reverses the central effects of an acutely intoxicating dose of ethanol in the rat. Using pharmacological magnetic resonance imaging (phMRI), we observed that LY404187 attenuated ethanol-induced reductions in blood oxygenation level dependent (BOLD) in the anesthetized rat brain. A similar attenuation was apparent when measuring local cerebral glucose utilization (LCGU) via C14-2-deoxyglucose autoradiography in freely moving conscious rats. Both LY404187 and LY451395 significantly and dose-dependently reversed ethanol-induced deficits in both motor coordination and disruptions in an operant task where animals were trained to press a lever for food reward. Both prophylactic and acute intervention treatment with LY404187 reversed ethanol-induced deficits in motor coordination. Given that LY451395 and related AMPA receptor potentiators/ampakines are tolerated in both healthy volunteers and elderly patients, these data suggest that such compounds may form a potential management strategy for acute alcohol intoxication.

    Here we investigated for the first time the inhibitory potential of Glycine (Gly) against ethanol-induced oxidative stress, neuroinflammation and apoptotic neurodegeneration in human neuroblastoma SH-SY5Y cells and in the developing rat brain. The Gly co-treatment significantly increased the cell viability, inhibited the expression of phospho-Nuclear Factor kappa B (p-NF-kB) and caspase-3 and reduced the oxidative stress in ethanol-treated SH-SY5Y cells in a PI3K-dependent manner. Seven days old male rat pups were injected with ethanol (5 g/kg subcutaneously, prepared in a 20% saline solution) and Gly (1 g/kg). Gly co-treatment stimulated the PI3K/Akt signaling pathway to limit the ethanol induced reactive oxygen species (ROS) production in the developing rat brain. It lowered the ethanol-elevated levels of phospho-c Jun N terminal kinase (p-JNK) and its various downstream apoptotic markers, including Bax, cytochrome C, caspase-3 and PARP-1. Additionally, the Gly treatment upregulated antiapoptotic Bcl-2 proteins and prevented ethanol-induced neurodegeneration as assessed by Fluoro-Jade-B (FJB) and Nissl staining. Furthermore, the Gly administration caused significant reduction in the ethanol-induced neuroinflammation by inhibiting the expression of inflammatory markers such as p-NF-kB, cyclooxygenase 2 (COX2) and tumor necrosis factor-α (TNF-α) and reversed the ethanol-induced synaptic protein markers expression. The results suggest that acute Gly treatment reduces ethanol-induced oxidative stress and neuronal cell loss in SH-SY5Y cells and in the developing rat brain. Therefore, Gly may be considered as potential treatment in ethanol-intoxicated newborns and infants. PMID:27058626

    Full Text Available OBJECTIVES: Guidelines to treat acute otitis media (AOM were published in 2004. Initial declines in prescribing were shown, but it's unknown if they were sustained. We examine trends in antibiotic dispensing patterns to treat AOM among a large population of children. We also document trends in antibiotic failure. STUDY DESIGN: Children aged 3 months to 12 years with an AOM diagnosis, enrolled in a commercial claims database between January 1, 2000-December 31, 2011 were included. Pharmacy claims within 7 days of diagnosis were searched for antibiotic prescriptions. Antibiotic failure was defined as a dispensing of a different antibiotic class within 2-18 days after the first prescription. We analyzed trends in antibiotic use and failure by class of antibiotic and year. RESULTS: We identified over 4 million children under 13 years with AOM. The proportion of antibiotic dispensing decreased from 66.0% in 2005 to 51.9% in 2007, after which the instances of dispensing rebounded to pre-guideline levels. However, levels began decreasing again in 2010 and the antibiotic use rate in 2011 was 57.6%. Cephalosporin prescriptions increased by 41.5% over eleven years. Antibiotic failure decreased slightly, and macrolides had the lowest proportion of failures, while all other classes had failure rates around 10%. CONCLUSIONS: In recent years, antibiotic dispensing to treat AOM remains high. In addition, the use of broad-spectrum antibiotics is increasing despite having a high rate of treatment failure. Overprescribing of antibiotics and use of non-penicillin therapy for AOM treatment could lead to the development of antibiotic-resistant infections.

    Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction, but whether major ozonated autohemotherapy affects remote injury remains poorly understood. Here, we assumed that major ozonated autohemotherapy contributes to recovery of clinical function, possibly by reducing remote injury after acute cerebral infarction. Sixty acute cerebral infarction patients aged 30-80 years were equally and randomly allocated to ozone treatment and control groups. Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy (47 mg/L, 100 mL ozone) for 10 ± 2 days. Patients in the control group received medical treatment only. National Institutes of Health Stroke Scale score, modified Rankin scale score, and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased, brain function improved, clinical efficiency significantly increased, and no obvious adverse reactions detected in the ozone treatment group compared with the control group. These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury, and additionally, exhibits high safety.

    The precise definition of a severe asthmatic exacerbation is an issue that presents difficulties. The term 'status asthmaticus' relates severity to outcome and has been used to define a severe asthmatic exacerbation that does not respond to and/or perilously delays the repetitive or continuous administration of short-acting inhaled beta(2)-adrenergic receptor agonists (SABA) in the emergency setting. However, a number of limitations exist concerning the quantification of unresponsiveness. Therefore, the term 'acute severe asthma' is widely used, relating severity mostly to a combination of the presenting signs and symptoms and the severity of the cardiorespiratory abnormalities observed, although it is well known that presentation does not foretell outcome. In an acute severe asthma episode, close observation plus aggressive administration of bronchodilators (SABAs plus ipratropium bromide via a nebulizer driven by oxygen) and oral or intravenous corticosteroids are necessary to arrest the progression to severe hypercapnic respiratory failure leading to a decrease in consciousness that requires intensive care unit (ICU) admission and, eventually, ventilatory support. Adjunctive therapies (intravenous magnesium sulfate and/or others) should be considered in order to avoid intubation. Management after admission to the hospital ward because of an incomplete response is similar. The decision to intubate is essentially based on clinical judgement. Although cardiac or respiratory arrest represents an absolute indication for intubation, the usual picture is that of a conscious patient struggling to breathe. Factors associated with the increased likelihood of intubation include exhaustion and fatigue despite maximal therapy, deteriorating mental status, refractory hypoxaemia, increasing hypercapnia, haemodynamic instability and impending coma or apnoea. To intubate, sedation is indicated in order to improve comfort, safety and patient-ventilator synchrony, while at the

    Lung-protective ventilation with a low tidal volume, plateau pressure 90% and permissive hypercapnia results in reduction of the mortality rate in patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). The level of the positive end-expiratory pressure (PEEP) must be chosen in relation to oxygen requirement. High frequency oscillatory ventilation and neurally adjusted ventilatory assist are promising methods. However, further studies with firm end-points have to be awaited before a final judgment is possible. Veno-venous extracorporeal membrane oxygenation (ECMO) can ensure life-sustaining gas exchange in patients with severe vitally compromised pulmonary failure, to provide time for lung tissue to heal and reduce ventilatory stress. The latest guidelines for analgesia and sedation in intensive care medicine demand consistent monitoring of the level of sedation and the intensity of pain. The sedation should be interrupted daily, with phases of awakenings and, if possible, spontaneous breathing. Methods of supportive treatment: Positional treatment (prone position) and inhalation of vasodilators can improve ventilation/perfusion mismatch and thus oxygenation. However, administration of surfactant is currently not advised in adult respiratory failure. PMID:21271478

Radix salviae miltiorrhizae (Danshen), a traditional herbal medicine, has a low price and a wide range of clinical applications. It is effective to promote blood lfow, eliminate stagnancy, and relieve pain. It is also found to be effective in treating AP. We reviewed the progress in research into the mechanism of Radix salviae miltiorrhizae in treatment of AP. DATA SOURCES: An english-language literature search was conducted using MEDLINE (1988-2005) on Radix salviae miltiorrhizae (Danshen) and acute pancreatitis. RESULTS:The mechanisms of Danshen in the treatment of AP include improvement of microcirculatory disturbances;elimination of oxygen free radicals; modulation of the metabolism of lipid inlfammatory mediator;and blocking of calcium inlfow and prevention of calcium overload. CONCLUSION:Danshen can effectively reduce the mortality and complications of AP.

    International Nuclear Information System (INIS)

    Objective: To explore the clinical value of intraarterial thrombolytic therapy for acute arterial occlusion of the extremities artery after trauma. Methods: Six cases with acute arterial occlusion of the extremities after trauma underwent intraarterial thrombolytic therapy and the efficiency was analysed. Results: Digital Subtraction Angiograph (DSA)clearly displayed the location, extent and dimensions of the occlusive extremity arteries. All the occlusive arteries were recanalized with successful rate of 100%. 4 cases appeared to have ischemia-reperfusion injury after treatment, outcoming with recovery in one case by musculoaponeuratic splitting, and 3 cases through medication; and simultaneously the pulse of the occlusive arteries returned to normal and the local pains reduced or disapeared afterwards; without serious complications of necrosis, hemorrhage etc. Conclusions: The intraarterial thrombolytic treatment of acute arterial occlusion of the extremities after trauma is safe, effective, minimal invasive and less complication; providing the preparation for further stent placement.

    Full Text Available The compound dichlorido-copper(II-4-(2-5-bromobenzylideneaminoethyl piperazin-1-ium phenolate (CuLBS was synthesized, characterized and screened for acute toxicity and protective activity against ethanol-induced gastric mucosal injury in rats. Gross microscopic lesions, biochemical and immunological parameters and histochemcial staining of glycogen storage were taken into consideration. Oral administration of CuLBS (30 and 60 mg/Kg for two weeks dose-dependently flattened gastric mucosa, significantly increased gastric mucus and total acidity, compared with control group (P < 0.01. Serum levels of liver enzymes aspartate (AST and alanine transaminases (ALT, pro-inflammatory (IL-6 and TNF-α and anti-inflammatory (IL-10 cytokines in the rats exposed to ethanol induced ulceration have been altered. Administration of CuLBS showed considerable (P < 0.05 protection against ulceration by modulating the acute alterations of cytokines AST, ALT and stomach glycogen. Interestingly, CuLBS did not interfere with the natural release of nitric oxide. CuLBS alone (60 mg/Kg did not exhibit any ulcerogenic effect as assessed using Adami’s scoring scale. An acute toxicity study showed that rats treated with CuLBS (1,000 and 2,000 mg/Kg manifested no abnormal signs. These findings therefore, suggested that the gastroprotective activity of CuLBS might contribute in modulating the inflammatory cytokine-mediated oxidative damage to gastric mucosa.

    Acute iron intoxication is one of the leading causes of overdose morbidity and mortality in children. The toxicity of iron has been postulated to be related to free radical formation and subsequent lipid peroxidation. Hyperbaric oxygen treatment can result in a number of beneficial biochemical, cellular and physiological effects, and has recently been shown to induce cellular protection against ischaemia, and in some cases against free radical formation. In the current study, we aimed to investigate the effects of hyperbaric oxygen treatment on mortality in acute iron intoxication in rats. After iron administration, 57 animals were divided into two groups: a treatment group receiving hyperbaric oxygen treatment (n = 30) and a control group (n = 27), and followed for 48 hr for signs of severe intoxication. In the second part of the study, 21 animals were divided into a treatment group receiving hyperbaric oxygen treatment (n = 10) and a control group (n = 11), and markers of oxidative stress were evaluated. We showed a significant reduction in mortality in hyperbaric oxygen-treated animals from 17 of 27 (62.9%) among untreated rats to 6 of 30 (20%). Surprisingly, in the treatment group, levels of oxidative stress markers were higher. We postulate that hyperbaric oxygen has a potentially beneficial effect in acute iron intoxication.

    Full Text Available PURPOSE: Although nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs and opioids are effective treatments for acute renal colic, they are associated with adverse events (AEs. As cyclooxygenase-2 selective NSAIDs may provide a safer alternative, we compared the efficacy and safety of parecoxib versus an nsNSAID in subjects with acute renal colic. MATERIALS AND METHODS: Phase IV., multicenter, double-blind, noninferiority, active-controlled study: 338 subjects with acute renal colic were randomized to parecoxib 40 mg i.v. plus placebo (n = 174 or ketoprofen 100 mg IV plus placebo (n = 164. 338 subjects with acute renal colic were randomized to parecoxib 40 mg IV (n = 174 or ketoprofen 100 mg IV(n = 164 plus placebo. Subjects were evaluated 15, 30, 45, 60, 90 and 120 minutes after treatment start and 24 hours after discharge. Primary endpoint was the mean pain intensity difference (PID at 30 minutes by visual analog scale (VAS (per-protocol population. An ANCOVA model was used with treatment group, country, and baseline score as covariates. Non-inferiority of parecoxib to ketoprofen was declared if the lower bound of the 95% confidence interval (CI for the difference between the two groups excluded the pre-established margin of 10 mm for the primary endpoint. RESULTS: Baseline demographics were similar. The mean (SD mPID30 min was 33.84 (24.61 and 35.16 (26.01 for parecoxib and ketoprofen, respectively. For treatment difference (parecoxib-ketoprofen the lower bound of the 95% CI was 6.53. The mean change from baseline in VAS 30 minutes after study medication was ~43 mm; AEs were comparable between treatments. CONCLUSIONS: Parecoxib is as effective as ketoprofen in the treatment of pain due to acute renal colic, is well tolerated, and has a comparable safety profile.

    Full Text Available Background Various indices have been raised as predictors of activity and severity of juvenile idiopathic arthritis. Objectives This study was conducted to investigate the changes of platelet indices in acute phase and two months after treatment in these patients. Patients and Methods In a cohort study, platelet count, mean platelet volume (MPV, platelet distribution width (PDW, plateletcrit (PCT were evaluated in children referred to children’s medical center, Tehran due to juvenile idiopathic arthritis from March 2013 to March 2014 during the acute phase and two months after standard treatment. The statistical data were analyzed by SPSS 19 software, and the significance level was set as P < 0.05. Results In this study, 55 children (24 boys and 31 girls with mean ± SD age of 7.50 ± 3.35 years were studied. The mean ± SD value of platelet count was 441872.7 ± 151836.9 in the acute phase and reached 395418.2 ± 119601.6 two months after treatment (P = 0.01. The mean ± SD PCT in the acute phase of various subtypes of the disease was 0.32 ± 0.11, which reached 0.29 ± 0.10 after treatment (P = 0.09. However, the PDW range in different subtypes of the disease reached 13.4 ± 8.0 from 13.9 ± 2.9 and MPV reached 8.7 ± 0.9 from 8.8 ± 1.1 after treatment, but they were not significantly different from the results in the acute phase (P = 0.5. Conclusions Platelet count is one of the most remarkable indices in JIA. Evaluation of PCT can also help determine the severity of the inflammatory process in the follow-up and treatment process.

    Full Text Available The basic disorder in acute gastroenteritis is the disrupted transport of water and electrolytes, to a different degree. The objective of these investigations was to evaluate the efficacy of two oral rehydration solutions (ORS in the treatment of acute gastroenteritis in suckling piglets. Fifty piglets, 20 with acute gastroenteritis and 30 healthy controls aged 10 days were chosen at random upon the incidence of diarrhea, for one of two ORS treatments (ORS-1 and ORS-2. The piglets with diarrhea were administered a probiotic per os on the first day and an antibiotic parenterally, until the diarrhea disappeared. All the piglets were followed clinically from days 1-6 of the investigations. Faeces samples were taken for bacteriological culture on the first day. Clinical signs of hydration were better, as well as the difference in body mass of piglets with diarrhea under the ORS-2 treatment which was significantly higher (p=0.036 in comparison with the difference in piglets under the ORS-1 treatment. All piglets with diarrhea had normally formed faeces on the sixth day. Escherichia coli was isolated from faeces of 48 piglets. Piglets with acute gastroenteritis, treated with ORS with a higher osmolarity and which contained instead of citrate, bicarbonates in higher concentrations, with less potassium, more sodium and more chlorine had a better state of hydration, with a significantly bigger difference in body mass, and the results of their control group were not significantly different against those of piglets treated with ORS of a different composition.

    1982-05-01

    A randomized study of graft irradiation in the treatment of acute rejection of renal transplants was conducted from 1978 to 1981. Patients developing clinical signs of an acute graft rejection received customary antirejection treatment in the form of intravenous administration of high-dose (1 gm per day) of methylprednisolone. They were at the same time randomized to either receive therapeutic irradiation (175 rad every other day to a total of 525 rad) or sham irradiation. Neither the patient nor the Transplant Service surgeons knew at any time whether the radiation treatment had been given. Eighty-three rejection episodes occurring in 64 grafts were entered into the study. Acute rejection was reversed in 84.5% of grafts in the control and 75% in the treated group. The incidence of recurrent rejection was higher in the treated group (66 vs. 46%) and graft survival was lower (22% vs. 54%). The study failed to demonstrate a beneficial effect of graft irradiation in the treatment of acute renal allograft rejection, when used in conjunction with high dose steriods.

    Mary-Louise Risher

    Full Text Available Adolescence is not only a critical period of late-stage neurological development in humans, but is also a period in which ethanol consumption is often at its highest. Given the prevalence of ethanol use during this vulnerable developmental period we assessed the long-term effects of chronic intermittent ethanol (CIE exposure during adolescence, compared to adulthood, on performance in the radial-arm maze (RAM and operant food-reinforced responding in male rats.Male Sprague Dawley rats were exposed to CIE (or saline and then allowed to recover. Animals were then trained in either the RAM task or an operant task using fixed- and progressive- ratio schedules. After baseline testing was completed all animals received an acute ethanol challenge while blood ethanol levels (BECs were monitored in a subset of animals. CIE exposure during adolescence, but not adulthood decreased the amount of time that animals spent in the open portions of the RAM arms (reminiscent of deficits in risk-reward integration and rendered animals more susceptible to the acute effects of an ethanol challenge on working memory tasks. The operant food reinforced task showed that these effects were not due to altered food motivation or to differential sensitivity to the nonspecific performance-disrupting effects of ethanol. However, CIE pre-treated animals had lower BEC levels than controls during the acute ethanol challenges indicating persistent pharmacokinetic tolerance to ethanol after the CIE treatment. There was little evidence of enduring effects of CIE alone on traditional measures of spatial and working memory.These effects indicate that adolescence is a time of selective vulnerability to the long-term effects of repeated ethanol exposure on neurobehavioral function and acute ethanol sensitivity. The positive and negative findings reported here help to further define the nature and extent of the impairments observed after adolescent CIE and provide direction for future

    2011-12-01

    Full Text Available Acute promyelocytic leukemia (APL is a distinct subtype of myeloid leukemia characterized by t(15;17 chromosomal translocation, which involves the retinoic acid receptor-alpha (RAR-alpha. APL typically presents with a life-threatening hemorrhagic diathesis. Before the introduction of all-trans retinoic acid (ATRA for the cure of APL, fatal hemorrhages due, at least in part, to the APL-associated coagulopathy, were a major cause of induction remission failure. The laboratory abnormalities of blood coagulation found in these patients are compatible with a syndrome of disseminated intravascular coagulation (DIC. Major determinants of the coagulopathy of APL are endogenous factors expressed by the leukemic cells, including procoagulant factors, fibrinolytic proteins, and non-specific proteolytic enzymes. In addition, these cells have an increased capacity to adhere to the vascular endothelium, and to secrete inflammatory cytokines [i.e. interleukin-1beta (IL-1beta and tumor necrosis factor (TNF-alpha], which in turn stimulate the expression of prothrombotic activities by endothelial cells and leukocytes. ATRA can interfere with each of the principal hemostatic properties of the leukemic cell, thus reducing the APL cell procoagulant potential, in parallel to the induction of cellular differentiation. This effect occurs in vivo, in the bone marrow of APL patients receiving ATRA, and is associated with the improvement of the bleeding symptoms. Therapy with arsenic trioxide (ATO also beneficially affects coagulation in APL. However, early deaths from bleeding still remain a major problem in APL and further research is required in this field. In this review, we will summarize our current knowledge of the pathogenesis of the APL-associated coagulopathy and will overview the therapeutic approaches for the management of this complication.

    Full Text Available CONTEXT: Drug-induced acute pancreatitis is a rather rare clinical entity. From time to time, several cases have been reported in which statins or salicylates have been associated with the development of acute pancreatitis. There is only one report which implies the involvement of both drugs in pancreatic inflammation. CASE REPORT: A 58-year-old Caucasian male with a history of coronary heart disease and hypercholesterolemia, under treatment with acetyl-salicylate for 6 years and simvastatin for 2 months, presented to the Emergency Department of our hospital with epigastric pain and vomiting of 24-hour duration. The clinical and laboratory investigation led to the diagnosis of acute pancreatitis. Conservative and rich-in-fluid treatment resulted in clinical and laboratory amelioration, and the patient was discharged on day 15, after full restoration of his health. In our patient, all possible common causes of acute pancreatitis were excluded. CONCLUSION: Conclusion It is a rational assumption to connect this case to the co-administration of simvastatin and acetyl-salicylate. However, the pathophysiological mechanism behind the onset of acute pancreatitis due to a statin, or, even more, due to its combination with salicylate, remains vague.

  13. Effects of chronic ethanol administration on hepatic glycoprotein secretion in the rat

    International Nuclear Information System (INIS)

    The effects of chronic ethanol feeding on protein and glycoprotein synthesis and secretion were studied in rat liver slices. Liver slices from rats fed ethanol for 4-5 wk showed a decreased ability to incorporate [14C]glucosamine into medium trichloracetic acid-precipitable proteins when compared to the pair-fed controls; however, the labeling of hepatocellular glycoproteins was unaffected by chronic ethanol treatment. Immunoprecipitation of radiolabeled secretory (serum) glycoproteins with antiserum against rat serum proteins showed a similar marked inhibition in the appearance of glucosamine-labeled proteins in the medium of slices from ethanol-fed rats. Minimal effects, however, were noted in the labeling of intracellular secretory glycoproteins. Protein synthesis, as determined by measuring [14C]leucine incorporation into medium and liver proteins, was decreased in liver slices from ethanol-fed rats as compared to the pair-fed controls. This was the case for both total proteins as well as immunoprecipitable secretory proteins, although the labeling of secretory proteins retained in the liver slices was reduced to a lesser extent than total radiolabeled hepatic proteins. When the terminal sugar, [14C]fucose, was employed as a precursor in order to more closely focus on the final steps of hepatic glycoprotein secretion, liver slices obtained from chronic ethanol-fed rats exhibited impaired secretion of fucose-labeled proteins into the medium. When ethanol (5 or 10 mM) was added to the incubation medium containing liver slices from the ethanol-fed rats, the alterations in protein and glycoprotein synthesis and secretion caused by the chronic ethanol treatment were further potentiated. The results of this study indicate that liver slices prepared from chronic ethanol-fed rats exhibit both impaired synthesis and secretion of proteins and glycoproteins, and these defects are further potentiated by acute ethanol administration

    Full Text Available FV: fluid volume; FV48: fluid volume administered during the initial 48 h; FVH: fluid volume during hospitalization; FVR: FV ratio as FV48/FVH An Italian survey on the treatment of acute pancreatitis published in 2007 [1] assessed the compliance of 56 medical and surgical centers equally distributed throughout Italy to the Italian guidelines on acute pancreatitis [2]. The severity of the disease was clinically assessed according to the Atlanta criteria [3] and the majority of patients were observed and treated early after the onset of acute pancreatitis; in fact, the mean interval between the onset of pain and hospital admission was 14.9±37.2 hours (mean±SD in patients with mild acute pancreatitis and 17.8±39.1 hours (mean±SD in those with severe pancreatitis. One of the results of this study was that the amount of fluids administered to acute pancreatitis patients was significantly higher in patients with severe acute pancreatitis than in those with the mild form. The appropriate fluid replacement may be one of reasons for the low mortality (3.1% observed in the patients with acute pancreatitis enrolled in this study. Low mortality due to early fluid administration is now supported by the findings of three recent studies coming from Japan and the United States [4, 5, 6]. In the first study we examined [4], the authors revised the data of 9,489 acute pancreatitis patients 18 years of age or older who were categorized into four study groups: ventilation, hemodialysis, a combination of ventilation and hemodialysis, and neither ventilation nor hemodialysis. They analyzed the fluid volume (FV administered during the initial 48 h (FV48 and during hospitalization (FVH, and calculated the FV ratio (FVR as FV48/FVH. The authors found that FV48 and FVR were higher in patients requiring ventilation as compared to those not requiring ventilation.

    The chemical composition, total flavonoids and antioxidant capacity of 50% ethanolic extracts from raw and cooked buckwheat flour from southwest of China were determined. The heat treatment used to gelatinize the flour starch significantly reduced the total flavonoids in the extract from 83.52 to 67.36 mg 100 g-1 of dry matter in the raw and cooked flour, respectively. The antioxidant capacity of the extracts was evaluated using autooxidation in a β-carotene-linoleate model system (AA or AAC), DPPH radical scavenging assay (IP) and oxygen radical absorbance capacity (ORAC) assay. Values for raw buckwheat flour extract were 97.84, 874.31, 76.45 and 94.92% for AA, AAC, ORAC and IP, respectively, while values in cooked buckwheat flour were 86.14, 842.88, 63.93 and 94.74% for AA, AAC, ORAC and IP, respectively. Values before cooked and raw buckwheat flour extracts were significantly different (P<0.05) for AA, AAC, and ORAC.

Four short-term, randomized, double-blind, placebo-controlled trials investigated the efficacy of paliperidone palmitate in acute exacerbation of schizophrenia. Paliperidone palmitate was also studied as a maintenance treatment to prevent or delay relapse in stable schizophrenia. In addition, paliperidone palmitate was compared to risperidone long-acting injection for noninferiority in three studies.Results: Paliperidone palmitate has been shown to be effective in reducing symptoms as measured by the Positive and Negative Syndrome Scale total scores in the four acute treatment studies. In the maintenance treatment studies, paliperidone palmitate was found to be more effective than placebo in preventing or delaying the time to first relapse in stable schizophrenia patients. In addition, paliperidone palmitate was shown to be noninferior to risperidone long-acting injection in two studies. It was shown to be reasonably well tolerated in all clinical trials. Acute treatment phase should be initiated with a dose of 234 mg on day one and 156 mg on day eight, followed by a recommended monthly maintenance dose of 39–234 mg based on efficacy and tolerability results from the clinical studies.Conclusion: Providing an optimal long-term treatment can be challenging. Paliperidone palmitate can be used as an acute treatment even in outpatient setting, and it has shown to be well tolerated by patients. Also, it does not require overlapping oral

    While the majority of children and adolescents with newly diagnosed childhood acute lymphoblastic leukemia (ALL) will be cured, as many as 20 % of patients will experience relapse. On current treatment regimens, the intensity of upfront treatment is stratified based upon prognostic factors with the aim of improving cure rates (for those at the highest risk of relapse) and minimizing treatment-related morbidity (for lower-risk patients). Here we review advances in the understanding of prognostic factors and their application. We also highlight novel treatment approaches aimed at improving outcomes in childhood ALL.

    There is little research literature on the conversion of lignocellulosic rich waste streams to ethanol, and even fewer have investigated both the technical aspects and environmental impacts together. This study assessed technical and environmental challenges of converting three lignocellulosic waste streams to ethanol: municipal solid waste (MSW), low grade mixed waste paper (MWP), and organic yard waste (YW). Experimental results showed high conversion yields for all three streams using suitable conversion methods. Environmental impacts are highly dependent on conversion technology, and process conditions used. Life cycle assessment results showed that both chemicals production and waste collection are important factors to be included within a waste-to-ethanol study. PMID:22119432

    Treatment outcomes of pediatric cancers have improved greatly with the development of improved treatment protocols, new drugs, and better supportive measures, resulting in overall survival rates greater than 70%. Survival rates are highest in acute lymphoblastic leukemia, reaching more than 90%, owing to risk-based treatment through multicenter clinical trials and protocols developed to prevent central nervous system relapse and testicular relapse in boys. New drugs including clofarabine and nelarabine are currently being evaluated in clinical trials, and other targeted agents are continuously being developed. Chimeric antigen receptor-modified T cells are now attracting interest for the treatment of recurrent or refractory disease. Stem cell transplantation is still the most effective treatment for pediatric acute myeloid leukemia (AML). However, in order to reduce treatment-related death after stem cell transplantation, there is need for improved treatments. New drugs and targeted agents are also needed for improved outcome of AML. Surgery and radiation therapy have been the mainstay for brain tumor treatment. However, chemotherapy is becoming more important for patients who are not eligible for radiotherapy owing to age. Stem cell transplant as a means of high dose chemotherapy and stem cell rescue is a new treatment modality and is often repeated for improved survival. Drugs such as temozolomide are new chemotherapeutic options. In order to achieve 100% cure in children with pediatric cancer, every possible treatment modality and effort should be considered.

The neurological deficit scores after treatment were obviously lower than the control group [(9.55±4.13)vs (15.46±4.92)], the differences were statistically significant.Conclusion: Hyperbaric oxygen combined with edaravone, salvia miltiorrhizae and ligustrazine and sodium ozagrel in the treatment of acute cerebral infarction can improve the symptoms of microcirculation and neurologic impairment, and improve the patient s quality of life.

  13. New developments in the treatment of the acute radiation syndrome

    International Nuclear Information System (INIS)

    Radiation accidents associated with the use of nuclear power, radiation devices and industrial applications have resulted in a number of individuals with significant partial or total body exposures, in a limited number with lethal outcome. Such exposures generally result in life-threatening suppression of bone marrow and immune functions and may be accompanied by high doses to the skin and underlying tissues. In recent years, new methods of diagnosis and treatment of such patients have entered development, while experience with relatively large-scale accidents, such as the Chernobyl cases, have clearly demonstrated the limitations of previous approaches. In particular bone marrow transplantation has met with limited success, mostly due to the inhomogeneous nature of accidental exposures as well as the frequent occurrence of other injuries other man bone marrow damage. Present day technology allows for direct estimates of the number of residual bone marrow stem cells to enable a rapid decision on the type of treatment indicated, while some twenty-five recombinant hemopoietic growth factors are under investigation to accelerate the recovery of white blood cells and platelets, as well as immune functions. If applied appropriately, such growth factor treatment will successfully replace bone marrow transplantation in the majority of accident cases. Advances in hemopoietic stem cell biology, both in terms of source of stem cells as well as their isolation, will on the other hand make stem cell infusion a much less risky operation than bone marrow transplantation has been in the past

    The cardioprotective effects of moderate alcohol consumption and statins have been known for years. However, heavy or binge drinking confers a high risk of cardiovascular disease. This study aimed to investigate the effects of different levels of alcohol consumption on acute myocardial infarction that was induced experimentally in rats, with a focus on the potential mechanism of angiogenesis and the effects of statins on heavy drinking. The experimental rats were fed low-dose ethanol (0.5 g/kg/day), high-dose ethanol (5 g/kg/day), and high-dose ethanol with rosuvastatin (10 mg/kg/day) during the entire experiment. Acute myocardial infarctions were induced 4 weeks after the beginning of the experiment. We assessed the capillary density in the myocardium via immunohistochemistry and quantified the expression of vascular endothelial growth factor (VEGF) and endostatin via enzyme-linked immunosorbent assay kits on the 4th day after myocardial infarction. The results revealed that low ethanol consumption promoted angiogenesis in association with higher VEGF and lower endostatin. High ethanol intake suppressed angiogenesis with unchanged VEGF and elevated endostatin. Treatment with rosuvastatin preserved angiogenesis following high ethanol intake, with an upregulation of VEGF. This study highlights that low ethanol consumption obviously promotes angiogenesis in myocardial-infarction rats while increasing the expression of VEGF, whereas high ethanol consumption inhibits ischemia-induced angiogenesis. This study also provides evidence that rosuvastatin alleviates the inhibitory effects of heavy drinking on angiogenesis. PMID:27565753

    1987-06-01

    Meat tenderizer containing the proteolytic enzyme papain was tested for therapeutic efficacy in the sting of the imported fire ant. The parameters of pain and itching were used to evaluate qualitatively the sting response in 22 healthy medical students, and the laser Doppler velocimeter was used to assess quantitatively the change in cutaneous blood flow. The results indicated that, during the acute-phase reaction, no clinically or statistically significant difference was found between stings treated with meat tenderizer and stings treated without tenderizer. Therefore we conclude that meat tenderizer is of no therapeutic value in the acute treatment of the imported fire ant sting. PMID:3597861

  16. Evaluation and Treatment of an Acute Internal Exposure to Plutonium

    International Nuclear Information System (INIS)

    As a result of an explosion caused by burning plutonium accidentally dropped into carbon tetrachloride, an individual was exposed internally to large amounts of plutonium. The skin of his entire body was contaminated to milligram quantities. The tip of the second finger, left hand, was severed. The left thumb had a severe laceration on the anterior surface at the interphalangeal joint, a compound fracture, and dislocation. There were several small lacerations on other fingers and back of the left hand. Small pieces of metal were driven into the hand. Treatment to reduce surface contamination consisted of shaving off hair and eyebrows and initial and daily washings of other parts of the body with sodium hypochlorite until contamination was reduced to acceptable levels. Evaluations of deposition in the thumb were done by measurement of 17 - keV X - rays. These evaluations led to the decision to amputate the thumb and finger. The individual was given DTPA treatment within 1 hour after injury and was placed on a subsequent schedule of periodic treatments. Rapid evalution of plutonium in urine and observations of the effectiveness of DTPA were accomplished by measurement of 14 - keV X - rays from the raw urine. The limit of detection by this method is 14 200 dpm per 24-h urine sample. This limit can be extended by an evaporation and dissolution technique to 570 dpm per 24-h urine sample. Accumulated urine excretion for the first 60 d was 117 μg. The individual was counted in the Rocky Flats Body Counter. Counts were made in the liver region, lung region, and left hand following amputation. Using a plastic human phantom for calibration, evaluations of lung and liver deposition were obtained. Evaluation of residual hand deposition was accomplished using a paraffin phantom for calibration and a positioning jig for the hand. Advantages of utilizing each of several available X - and gamma - ray energies were determined. (author)

    Cough represents one of the most common reasons for pediatrician consultations. There are many available treatments for symptomatic relief, including honey. Despite its wide availability, there is little knowledge about its benefits. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including three randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded the use of honey probably decreases the severity and frequency of cough, improves the quality of parent's and patient's sleep, and does not have side effects. PMID:27280298

    Acute soft tissue injuries create pain and limitation of function. Treatment requires analgesia and time for full recovery. Acetaminophen with codeine (650 mg plus 60 mg, respectively, every 4 to 6 hours) is used frequently as the analgesic of choice. Diflunisal (1,000 mg initially then 500 mg twice a day) vs acetaminophen with codeine was prospectively studied in the treatment of acute mild to moderate pain from soft tissue injuries. Thirty-five patients with acute strains, sprains, or low back pain were randomized to treatment (17 acetaminophen with codeine vs 18 diflunisal). Both groups were similar in the amount of pain and type of injury at initiation of therapy. Patient pain rating went from 3.3 +/- 0.6 to 1.6 +/- 1.5 for acetaminophen with codeine and from 3.3 +/- 0.6 to 1.3 +/- 1.1 for diflunisal. However, 65 percent of acetaminophen with codeine patients experienced side effects, with 35 percent of these patients stopping the medication because of intolerable side effects. In the diflunisal group, 28 percent of the patients experienced side effects and 5 percent had to stop the medication early. Diflunisal was found to be an effective analgesic in mild to moderate pain of acute soft tissue injuries, and caused fewer and more tolerable side effects than did acetaminophen with codeine.

    Acupuncture is an ancient medical treatment that is increasingly attracting the interest of the public. It is a complementary therapy that is widely used for management of pain, especially chronic discomfort caused by migraine, low-back pain and osteoarthritis of the knee(¹⁻³). The evidence base for the effectiveness of acupuncture and its clinical applications is controversial, and although its efficacy and safety in the management of acute pain have been demonstrated, the quality of this modality is still questionable. The present study reports a case of acute ankle injury, which was treated with acupuncture. A 33-year-old man presented with acute twisted ankle injury. He had pain with swelling around the ankle, and he was experiencing difficulty in walking. His clinical diagnosis was acute ankle sprain with severe pain. Several drug treatments are used for pain control, but in this case, we used acupuncture. After treatment, his pain diminished significantly with a decrease in VAS pain level from 8 to 4 in 20 minutes. At follow-up after one month, we found no skin infection in this case. PMID:27266242

    Objective:To explore the clinical efficacy of oxygen-driven atomizing inhalation of budesonide in the treatment of acute laryngitis.Methods:Based on the routine treatment, the patients in the observation group were given oxygen-driven atomizing inhalation of budesonide, while the patients in the control group were given oxygen-driven atomizing inhalation of dexamethasone. The change of SpO2 before treatment and 30 min after treatment, the changes of serum IL-4 and IL-8 before treatment and 3 d after treatment, the clinical symptom disappearing time, hospitalization time, and clinical therapeutic effect after drug administration in the two groups were observed.Results: The improved degree of SpO2 30 min after treatment in the observation group was significantly superior to that in the control group. The decreased degree of IL-4 and IL-8 levels 3 d after treatment in the observation group was significantly superior to that in the control group. The clinical symptom disappearing time and hospitalization time in the observation group were significantly shorter than those in the control group. The total effective rate in the observation group (94.3%) was significantly superior to that in the control group (74.3%).Conclusions:Oxygen-driven atomizing inhalation of budesonide in the treatment of acute laryngitis can rapidly alleviate the local inflammatory reaction, improve the clinical symptoms, and enhance the safety of drug administration; therefore, it deserves to be widely recommended in the clinic.

    Objective: To observe the therapeutic effect of acupuncture combined with medicines for acute cerebral infarction and to study its mechanism. Methods: A total of 80 acute cerebral infarction patients were evenly randomized into treatment and control groups. Patients of treatment group were treated with acupuncture of Baihui (百会GV 20), Fengchi (风池GB 20), Jiquan (极泉HT 1), Neiguan (内关PC 6), etc. and those of control group treated with conventional medicines as low molecular dextran, compound Red Sage injection, Citicolinum, etc. Scores of clinical neurological deficits, blood flow velocity peak (Vp) and mean blood flow velocity (Vm) of the bilateral internal carotid artery (ICA), middle cerebral artery (MCA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), basilar artery (BA) and vertebral artery (VA) were detected with transcranial Doppler (TCD) were analyzed before and after treatment. Results: After 12 days' treatment, the neurological deficit scores in both treatment and control groups decreased significantly, and the difference values of the score of the former group was significantly bigger than these of the later group (P<0.01). Vp and Vm of all the detected arteries in treatment group and bilateral ACA, MCA and PCA of control group increased significantly in comparison with pre-treatment (P<0.05, P<0.01); and the difference values of Vm of bilateral MCA and VA (between post- and pre-treatment) of treatment group were significantly bigger than those of control group (P<0.01). Conclusion: The therapeutic effect of acupuncture combined with medication is significantly superior to that of simple medication in the treatment of acute cerebral infarction.

    Cranial MRI was used to study treatment-related changes in children undergoing therapy for acute lymphoblastic leukaemia (ALL) or lymphoma. Nineteen children (18 with ALL, 1 with lymphoma) underwent MRI at the beginning of treatment and at intervals during it, to a total of 105 imaging studies and a minimum of 3 per case. Nine patients had finished all therapy, all received consolidation treatment. No patient had central nervous system (CNS) leukaemia at diagnosis or developed a CNS relapse. Mild treatment-related white matter changes were observed in only 2 patients after consolidation therapy with three 5 g/m{sup 2} pulses of intravenous methotrexate. Transient enlargement of the ventricles and cortical sulci was observed in 13 patients, always temporally related to steroid treatment. These preliminary data suggest that treatment-related white matter changes are rare and no routine MRI follow-up is needed during treatment in asymptomatic children after a baseline assessment.

    Full Text Available The role of hyperbaric oxygen therapy (HBOT in the treatment of acute ischemic stroke is controversial. This prospective study assessed the efficacy and safety of HBOT as adjuvant treatment on 46 acute ischemic stroke in patients who did not receive thrombolytic therapy. The HBOT group (n=16 received conventional medical treatment with 10 sessions of adjunctive HBOT within 3–5 days after stroke onset, while the control group (n=30 received the same treatment but without HBOT. Early (around two weeks after onset and late (one month after onset outcomes (National Institutes of Health Stroke Scale, NIHSS scores and efficacy (changes of NIHSS scores of HBOT were evaluated. The baseline clinical characteristics were similar in both groups. Both early and late outcomes of the HBOT group showed significant difference (P≤0.001. In the control group, there was only significant difference in early outcome (P=0.004. For early efficacy, there was no difference when comparing changes of NIHSS scores between the two groups (P=0.140 but there was statistically significant difference when comparing changes of NIHSS scores at one month (P≤0.001. The HBOT used in this study may be effective for patients with acute ischemic stroke and is a safe and harmless adjunctive treatment.

    BACKGROUND: With the development of the associated technology, interventional treatment has become an important method for the treatment of hepatic artery occlusion in some countries. This study was undertaken to evaluate the role of interventional methods in the diagnosis and treatment of acute hepatic artery occlusion after liver transplantation. METHODS: The diagnosis and treatment of 9 cases of acute hepatic artery occlusion after liver transplantation were retrospectively analyzed. RESULTS: In 109 cases of liver transplantation, 9 were diagnosed by angiography. Among them, 7 were diagnosed by Doppler ultrasound. After transcatheter thrombolysis, the hepatic arteries were partially or totally patent again in 6 cases of hepatic artery occlusion after liver transplantation, and stent placements in the hepatic artery were performed in 5 cases. All stents proved patent and no patient required another liver transplantation. CONCLUSIONS: Angiography plays an important role in diagnosing hepatic artery complications after liver transplantation. Interventional therapy is a valuable method in the treatment of acute hepatic artery occlusion after liver transplantation.

    Developing new treatment strategies for acute ischemic stroke in the last twenty years has offered some important successes, but also several failures. Most trials of neuroprotective therapies have been uniformly negative to date. Recent research has reported how excitatory amino acids act as the major excitatory neurotransmitters in the cerebral cortex and hippocampus. Furthermore, other therapeutic targets such as free radical scavenger strategies and the anti-inflammatory neuroprotective strategy have been evaluated with conflicting data in animal models and human subjects with acute ischemic stroke. Whereas promising combinations of neuroprotection and neurorecovery, such as citicoline, albumin and cerebrolysin have been tested with findings worthy of further evaluation in larger randomized clinical trials. Understanding the complexities of the ischemic cascade is essential to developing pharmacological targets for acute ischemic stroke in neuroprotective or flow restoration therapeutic strategies.

    Acute exacerbations of Crohn's disease are usually treated with prednisolone or potentially more toxic immunosuppressive drugs or by surgery. In pilot studies replacing the normal diet by a protein free elemental diet also induced remission. A controlled trial was therefore conducted in which 21 patients acutely ill with exacerbations of Crohn's disease were randomised to receive either prednisolone 0.75 mg/kg/day or an elemental diet (Vivonex) for four weeks. Assessment at four and 12 weeks showed that the patients treated with the elemental diet had improved as much as and by some criteria more than the steroid treated group. Elemental diet is a safe and effective treatment for acute Crohn's disease. PMID:6428577

  9. Therapeutic effectiveness and safety parathyroid adenoma ablation with percutaneous ethanol injection under sonographic guidance in patients with chronic renal failure and secondary hyperparathyroidism refractory to medical treatment

    International Nuclear Information System (INIS)

    Secondary hyperparathyroidism unresponsive to medical treatment is a common complication in patients with chronic renal failure and prolonged dialysis therapy, which requires surgery of the parathyroid glands, with the risks and costs of surgery. Objective: To evaluate the therapeutic effectiveness and safety of ablation of parathyroid adenomas by percutaneous ethanol injection under ultrasound guidance. Method: After approval by the institutional medical ethics committee, informed written consent was obtained in 15 patients who met the inclusion criteria. Sonographically guided ethanol was injected consecutively into adenomas, with an interval of time less than six months. Results: Size, Doppler vascularity of adenomas, and the levels of parathyroid hormone, calcium and phosphorus were measured before and after ablation as criteria for treatment response in 15 patients. Of all patients, six (40%) had no therapeutic response. Therapeutic response was observed in nine patients (60%). In the latter group, five patients (33.3%) had successful response and symptomatic improvement, in two patients (13.3%), therapeutic response was suboptimal, and in two patients (13.3%), the response was unsatisfactory. The procedure was safe. Local pain, transient dysphonia and cough were considered minor complications and were the most common, with resolution in all cases. There were no major complications. Conclusion: Ablation of parathyroid adenomas with percutaneous ethanol injection and ultrasound guidance, in uremic patients with secondary hyperparathyroidism unresponsive to medical treatment is an effective and safe therapy. Studies involving more patients and longer follow up are needed in order to stablish more conclusive results

    Background Fibrinogen-depleting agents are promising in the treatment of cerebral ischemic disease. They were studied by many trials, and the outcomes were different because of different regimens and different doses. In this study, we assessed the efficacy and safety of defibrase on acute cerebral infarction in China.Methods A search using Chinese hospital knowledge database (CHKD) and MEDLINE database for randomized controlled trials was carried out. A CHKD (1994 June 2005) search was performed with the keyword "defibrase", then a second search for the keyword "acute cerebral infarction"; a MEDLINE search (1950 June 2005) was performed with the following keywords: [(cerebral ischemia), OR (acute cerebral infarction), OR (stroke)], AND [defibrase]. Meta-analysis was performed with RevMan software 4.2.Results Included were 14 studies comparing the efficiency and safety of defibrase with other drugs in the treatment of acute cerebral infarction. Patients' records were pooled (total 646 patients; defibrase, n=328, no defibrase n=318). Neurological deficit score (NDS) before treatment showed weighted mean differences (WMD)=0.95, 95% confidence interval (CI)= (-0.60, 2.50), P=0.23; NDS after treatment showed WMD=-2.20, 95% CI= (-4.21, -0.18), P=0.03; Barthel index at 3 months showed WMD=4.45, 95% CI= (-0.13, 9.03), P=0.06; the plasma fibrinogen level before treatment showed WMD=0.02, 95% CI= (-0.16, 0.19), P=0.86; plasma fibrinogen level after treatment showed WMD=-1.51, 95% CI= (-1.88, -1.15), P<0.00 001. Conclusions With the given dose and regimen of defibrase in China, defibrase may play a role of anticoagulation. It might inhibit the progression of stroke and prevent the recurrence of stroke.

    Pharmacologic modulation of hypermetabolism clearly benefits children with major burns, however, its role in adult burns remains to be defined. Oxandrolone appears to be a promising anabolic agent although few outcome data are as yet available. We examined whether early oxandrolone treatment in severely burned adults was associated with improved outcomes during acute hospitalization. We evaluated for potential associations between oxandrolone treatment and outcomes in a large cohort of severely burned adults in the context of a multicenter observational study. Patients were dichotomized with respect to oxandrolone treatment, defined as administration within 7 days after admission, with duration of at least 7 days. Acute hospitalization outcomes were compared with univariate and multivariate analyses. One hundred seventeen patients were included in this analysis. Mean patient age was 42.6 years (range, 18–86); 77% were male, with an average TBSA of 44.1%. Baseline and injury characteristics were similar among treatment and nontreatment cohorts. Oxandrolone treatment (N =59) did not impact length of stay but was associated with a lower mortality rate (P = .01) by univariate analysis. Oxandrolone treatment was independently associated with higher survival by adjusted analyses (P = .02). Examination of early oxandrolone treatment in this cohort of severely burned adults suggests that this therapy is safe and may be associated with improved survival. Further studies are necessary to define the exact mechanisms by which oxandrolone is beneficial during inpatient treatment. PMID:18849836

    Full Text Available Diagnostic criteria and treatment protocols for acute antibody-mediated rejection (AMR of kidney allograft remain controversial. We report the case of early severe AMR after primary kidney transplantation. The graft removal was considered in the absence of treatment efficacy and in the presence of systemic infl ammatory response syndrome. However, at surgery the graft looked normal and it was not removed. The repeated treatment course (plasmapheresis, antithymocyte globulin, intravenous immunoglobulin and rituximab was effective. The patient has good and stable graft function in 1 year after transplantation.

    Coupled plasma filtration adsorption (CPFA) is an extracorporeal blood purification therapy based on non-specific pro- and anti-inflammatory mediator adsorption on a special resin cartridge coupled with continuous veno-venous haemofiltration or continuous veno-venous haemodiafiltration and is one of the emerging treatments for septic patients. However, in the literature, there are limited data about its efficacy in treating patients with acute diseases but without the traditional criteria for sepsis. We describe the case of a 43-year-old male who developed acute respiratory distress syndrome secondary to pneumonia and acute kidney injury, whose clinical conditions rapidly improved after early CPFA therapy.

    Full Text Available Naoki Aikawa,1 Yasushi Kawasaki2 1School of Medicine, Keio University, Tokyo, 2Ono Pharmaceutical Co, Ltd, Osaka, Japan Abstract: Acute respiratory distress syndrome is a serious condition that can arise following direct or indirect lung injury. It is heterogeneous and has a high mortality rate. Supportive care is the mainstay of treatment and there is no definitive pharmacological treatment as yet. Sivelestat is a neutrophil elastase inhibitor approved in Japan and the Republic of Korea for acute lung injury, including acute respiratory distress syndrome in patients with systemic inflammatory response syndrome. The aim of this review is to examine the clinical utility of sivelestat in different disease states, using data from nonclinical and clinical studies. In nonclinical studies, sivelestat appears to show benefit in acute lung injury without inhibiting the host immune defense in cases of infection. Clinical studies do not yet provide a clear consensus. Phase III and IV Japanese studies have shown improvements in pulmonary function, length of intensive care unit stay, and mechanical ventilation, but a non-Japanese multicenter study did not demonstrate sivelestat to have an effect on ventilator-free days or 28-day all-cause mortality. Evidence of improvement in various parameters, including duration of stay in intensive care, mechanical ventilation, the ratio of partial pressure of arterial oxygen and fraction of inspired oxygen (PaO2/FIO2 ratio ratio, and lung injury scores, has been shown in patients with sepsis or gastric aspiration, and following the surgical treatment of esophageal cancer. To date, there are no particular concerns regarding adverse events, and the available data do not suggest that sivelestat might worsen infections. One study has analyzed cost-effectiveness, finding that sivelestat may reduce costs compared with standard care. The currently available evidence suggests that sivelestat may show some benefit in the

    Acute heart failure remains a major cause of morbidity, and its treatment requires an increasing investment of the health care system. Whereas success in treating chronic heart failure has been achieved over the last decades, several pharmacological approaches for acute heart failure have been introduced but have failed to demonstrate any clinical benefit. Serelaxin is a recombinant human relaxin-2 vasoactive peptide that causes systemic and renal vasodilation. Data suggest that the clinical benefits may be attributable to a potential combination of multiple actions of serelaxin, including improving systemic, cardiac, and renal hemodynamics, and protecting cells and organs from damage via neurohormonal, anti-inflammatory, antiremodeling, antifibrotic, anti-ischemic, and proangiogenic effects. Recently, a number of clinical trials have demonstrated that serelaxin infusion over 48 hours improved dyspnea with more rapid relief of congestion during the first days after admission for heart failure. In addition, administration of serelaxin diminished cardiac, renal, and hepatic damage, which were associated with improved long-term mortality. Available data support substantial clinical benefits and significant promise for serelaxin as a treatment option for patients with acute heart failure. This review focuses on the pharmacology and mechanisms of action of serelaxin and provides a detailed discussion of the clinical evidence for this novel therapy in acute heart failure. PMID:26331289

    2015-04-01

    The management of patients with acute pulmonary embolism is made challenging by its wide spectrum of clinical presentation and outcome, which is mainly related to patient haemodynamic status and right ventricular overload. Mechanical embolic obstruction and neurohumorally mediated pulmonary vasoconstriction are responsible for right ventricular overload. The pathophysiology of acute pulmonary embolism is the basis for risk stratification of patients as being at high, intermediate and low risk of adverse outcomes. This risk stratification has been advocated to tailor clinical management according to the severity of pulmonary embolism. Anticoagulation is the mainstay of the treatment of acute pulmonary embolism. New direct oral anticoagulants, which are easier to use than conventional anticoagulants, have been compared with conventional anticoagulation in five randomised clinical trials including >11 000 patients with pulmonary embolism. Patients at high risk of pulmonary embolism (those with haemodynamic compromise) were excluded from these studies. Direct oral anticoagulants have been shown to be as effective and at least as safe as conventional anticoagulation in patients with pulmonary embolism without haemodynamic compromise, who are the majority of patients with this disease. Whether these agents are appropriate for the acute-phase treatment of patients at intermediate-high risk pulmonary embolism (those with both right ventricle dysfunction and injury) regardless of any risk stratification remains undefined.

    In the past months significant new data have been published in the field of headache and migraine. With the publication of the second and revised version of the classification of headache disorders, new entities such as chronic migraine have been introduced. Moreover, the repertoire of drugs available for the treatment of migraine has changed as well. Whereas ergot derivatives have been almost completely taken off the market, seven triptans in 23 different preparations are now available and allow the physician to customize the treatment of acute attacks. CGRP antagonists, a completely new generation of anti-migraine compounds for the treatment of acute attacks, have now been tested successfully in clinical trials. For the prophylaxis of migraine, several agents that had been well established for decades have recently been taken off the market too, but new agents such as topiramate, which possesses different modes of action, have been tested successfully and are now available for the prophylaxis of migraine. The following review will summarize the newest developments in acute therapy and prophylactic treatment of migraine.

    We performed a meta-analysis for systematic evaluation of the status quo of catheter thrombolysis for the treatment of acute lower limb deep vein thrombosis in China. We searched the China Biomedical bibliographic database (CBM), China National Knowledge Infrastructure (CNKI), Weipu full-text electronic journals, Wanfang full-text database, and Medline (1990 through June 2011) for clinical randomized controlled trials of catheter-directed thrombolysis and superficial venous thrombolysis to compare their efficacies for the treatment of acute deep vein thrombosis. The results were analyzed by using the Cochrane-recommended RevMan 4.2 software package, and the odds ratio (OR) was used as the combined measure of efficacy. The search retrieved 8 randomized controlled trials, and meta-analysis using the total rate of effective treatment as the clinical observation index found that the combined OR for the catheter thrombolysis group versus the superficial venous thrombolysis group was significant (P venous thrombolysis for the treatment of acute deep vein thrombosis in the lower limb in Chinese individuals. However, the included trials were only of medium quality, so more rational and scientific clinical trials are needed to validate this conclusion.

    Two men aged 19 and 21 years ingested 1 g and 4 g respectively from 3 kg of a white crystalline powder that they thought was a substance of abuse. It was later identified as almost pure arsenic trioxide. Both had nausea and vomiting and one developed acute renal failure. Each was treated with 2,3-dimercaptopropanesulphonate (DMPS), and made a full recovery with no evidence of prolonged renal or neurological impairment. The DMPS-arsenic complex is probably associated with lower penetration into the CNS and as a consequence treatment with DMPS may result in lower acute and chronic neurotoxicity than treatment with the currently standard recommended chelating agent dimercaprol (British Anti-Lewisite; BAL).

    1984-02-01

    Full Text Available Childhood leukemia, especially acute lymphocytic leukemia, can now be completely cured by a multimodality approach in one out of every two patients. Since prolonged maintenance therapy with anti-cancer agents for three years is required for complete cure, a significant problem during this course of treatment is death due to secondary infection. Those with childhood leukemia receiving anti-cancer chemotherapy who became secondarily injected with chicken pox can now be treated successfully with interferon in the four cases reported here. Chicken pox was cured even while one of them was in relapse. Therefore, it can be said that a bright prospect, namely interferon, is on the horizon in the treatment of secondary viral diseases associated with acute leukemia.

    2012-02-01

    Endovascular stent graft treatment of acute thoracic aortic transections is an encouraging minimally invasive alternative to open surgical repair. Between 2006 and 2008, 16 patients with acute thoracic aortic transections underwent evaluation at our institution. Seven patients who were treated with an endovascular stent graft were reviewed. The mean Glasgow Coma Score was 13.0, probability of survival was .89, and median injury severity score was 32. The mean number of intensive care unit days was 7.7, mean number of ventilator support days was 5.4, and hospital length of stay was 10 days. Mean blood loss was 285 mL, and operative time was 143 minutes. Overall mortality was 14%. Procedure complications were a bleeding arteriotomy site and an endoleak. Endovascular treatment of traumatic thoracic aortic transections appears to demonstrate superior results with respect to mortality, blood loss, operative time, paraplegia, and procedure-related complications when compared with open surgical repair literature.

    The aims of our experiments on animals were (i) to evaluate by direct oximery the efficiency of various antioxidant drugs in a complex treatment of acute pancreatitis and (ii) to determine the diagnostic value of the direct oximetry method for estimation of the efficiency of medical treatment. The article presents data obtained in a group 75 outbred Guinea with a model acute pancreatitis, which were treated with mexibel (group 1), emoxipin (group 2), end cytoflavin (group 3), with subsequent investigation of the pancreatic tissues by the direct oximetry method. The obtained results confirmed that the intraperitoneal injection of cytoflavin to animals stimulates tissue respiration, improves metabolism, promotes pancreas recovery, and also improves the prognosis and reduces the lethal outcome. The efficiency of cytoflavin within the complex therapy exceeds the effect of other antioxidants (mexibel and emoxipin) under otherwise equal conditions.

    Relapse is the main reason for treatment failure in childhood acute lymphoblastic leukemia. Despite improvements in the up-front therapy, survival after relapse is still relatively poor, especially for high-risk relapses. The aims of this study were to assess outcomes following acute lymphoblastic leukemia relapse after common initial Nordic Society of Paediatric Haematology and Oncology protocol treatment; to validate currently used risk stratifications, and identify additional prognostic factors for overall survival. Altogether, 516 of 2735 patients (18.9%) relapsed between 1992 and 2011 and were included in the study. There were no statistically significant differences in outcome between the up-front protocols or between the relapse protocols used, but an improvement over time was observed.

    It has been consistently observed that patients with renal dysfunction have more premature, severe, complicated, and fatal cardiovascular disease than age- and sex-matched individuals with normal renal function. There have been 4 major explanations for this finding: (1) positive confounding by third variables associated with chronic kidney disease (CKD), including diabetes mellitus and hypertension; (2) therapeutic nihilism or lesser use of beneficial therapies in CKD; (3) greater toxicities of therapies, such as bleeding from anticoagulants or contrast-induced kidney injury; (4) biological factors which result directly from CKD that work to promote and accelerate cardiovascular disease. In this paper, we focus on the issue of treatment disparities or therapeutic nihilism and its contribution to poor outcomes in the setting of acute coronary syndromes and acutely decompensated heart failure. This issue is important because if we can overcome barriers to the utilization of beneficial treatments, then clinical outcomes should improve over time. PMID:21625092

    The efficiency of a new peptide medicine-Prostatilen was studied when using it in acute postoperative retention of urine. Under observation there were 87 patients of 23-78 years of age after hemorrhoidectomy, plasty of the rectal sphincter or dissection of its fissure etc. The patients endured the treatment with Prostatilen well. Self-dependent urination was recovered during the nearest 40 min after injection of 5 mg of the medicine. In the treatment of 23 patients it was used prophylactically before the appearance of a micturate urge. In 14 of them the postoperative period was smooth, in 9 patients the self-dependent urination was recovered following one additional injection. Clinical observations confirm that Proctatilen has a regulating effect upon the bladder tone which allows it to be recommended as a medicine for prevention of acute reflex retention of urine after operations in the area of the rectal sphincter.

    Milk production loss after recovery from acute coliform mastitis causes major economic losses for dairy industries. Declines in milk production and composition are caused by multiple factors, including cow factors, microorganisms and treatments, but the influence of each factor has not been determined. To investigate risk factors for milk loss after treatment for acute coliform mastitis, multiple logistic regression analyses were conducted in 53 clinical cases. Systemic administration of fluoroquinolone was significantly associated with recovery of marketable milk production. The time to slaughter was significantly shorter in cows with complete loss of quarter milk production than in cows that produced marketable milk. In this study, we identified factors associated with increased risk of milk production loss. PMID:26860356

    Amoxicillin is a first-line antibiotic treatment for acute otitis media in children and one of the most commonly used antibiotics for human bacterial infections. We investigated changes in salivary bacterial communities among children treated with amoxicillin for acute otitis media (n = 18), using a culture-independent approach based on pyrosequencing of the V3 region of the bacterial 16S rRNA gene. The control group consisted of children with acute otitis media who were not given antibiotics (n = 15). One species-level phylotype assigned to the genus Streptococcus was identified across all (n = 99) saliva samples. Two additional species-level phylotypes from the genera Gemella and Granulicatella were shared by all (n = 45) samples of control subjects. Amoxicillin treatment resulted in reduced species richness and diversity, and a significant shift in the relative abundance of 35 taxa at different ranks from phylum to species-level phylotype. At the phylum level, prevalence of TM7 and Actinobacteria decreased at the end of treatment, whereas Proteobacteria had a higher relative abundance post-treatment. Multivariate analysis showed that samples from the same control subject taken over time intervals tended to cluster together. Among antibiotic-treated subjects, samples taken before and at the end of amoxicillin treatment formed two relatively well-separated clusters both of which greatly overlapped with samples taken about 3 weeks post-treatment. Our results point to a substantial but incomplete recovery of the salivary bacterial community from the antibiotic about 3 weeks after the end of treatment.

    Full Text Available Abstract Background The challenge of Bipolar Disorder (BD treatment is due to the complexity of the disease. Current guidelines represent an effort to help clinicians in their everyday practice but still have limitations, specially concerning to long term treatment. LICAVAL (efficacy and tolerability of the combination of LIthium and CArbamazepine compared to lithium and VALproic acid in the treatment of young bipolar patients study aim to evaluate acute and maintenance phase of BD treatment with two combined drugs. Methods LICAVAL is a single site, parallel group, randomized, outcome assessor blinded trial. BD I patients according to the DSM-IV-TR, in depressive, manic,/hypomanic or mixed episode, aged 18 to 35 years are eligible. After the diagnostic assessments, the patients are allocated for one of the groups of treatment (lithium + valproic acid or lithium + carbamazepine. Patients will be followed up for 8 weeks in phase I (acute treatment, 6 months in phase II (continuation treatment and 12 months in phase III (maintenance treatment. Outcome assessors are blind to the treatment. The main outcome is the evaluation of changes in mean scores on CGI-BP-M between baseline and endpoint at the end of each phase of the study. Results LICAVAL is currently in progress, with patients in phase I, II or III. It will extended until august 2012. Conclusions Trials comparing specific treatments efficacy in BD (head to head can show relevant information in clinical practice. Long term treatment is an issue of great important and should be evaluated carefully in more studies as long as BD is a chronic disease. Trial registration ClinicalTrials.gov Identifier: NCT00976794

Davis Jewish General Hospital, Montréal, Canada; 2Global Drug Safety, Grünenthal GmbH, Aachen, Germany; 3Johnson & Johnson Pharmaceutical Research and Development, L.L.C., Raritan, New Jersey, USAAbstract: The undertreatment of acute pain is common in many health care settings. Insufficient management of acute pain may lead to poor patient outcomes and potentially life-threatening complications. Opioids provide relief of moderate to severe acute pain; however, therapy with pure µ-opioid agonists is often limited by the prevalence of side effects, particularly opioid-induced nausea and vomiting. Tapentadol is a novel, centrally acting analgesic with 2 mechanisms of action, µ-opioid receptor agonism and norepinephrine reuptake inhibition. The analgesic effects of tapentadol are independent of metabolic activation and tapentadol has no active metabolites; therefore, in theory, tapentadol may be associated with a low potential for interindividual efficacy variations and drug–drug interactions. Previous phase 3 trials in patients with various types of moderate to severe acute pain have shown that tapentadol immediate release (IR; 50 to 100 mg every 4 to 6 hours provides analgesia comparable to that provided by the pure µ-opioid agonist comparator, oxycodone HCl IR (10 or 15 mg every 4 to 6 hours, with a lower incidence of nausea, vomiting, and constipation. Findings suggest tapentadol may represent an improved treatment option for acute pain.Keywords: tapentadol IR, acute pain, opioid, gastrointestinal tolerability

    The optimal treatment for schizoaffective disorder (SCA) is not well established. In this initial 6-month open-label treatment period of a large, multiphase, relapse-prevention study, the efficacy and safety of paliperidone palmitate once-monthly (PP1M) injectable were evaluated in subjects with symptomatic SCA. Subjects with acute exacerbation of SCA (ie, with psychotic and either depressive and/or manic symptoms) were enrolled and treated with PP1M either as monotherapy or in combination with antidepressants or mood stabilizers (combination therapy group). After flexible-dose treatment with PP1M for 13 weeks, stabilized subjects continued into a 12-week fixed-dose PP1M treatment period. A total of 667 subjects were enrolled; 320 received monotherapy and 347 received PP1M as combination therapy; 334 subjects completed the entire 25-week treatment. Statistically significant and clinically meaningful improvements from baseline were observed for all efficacy measures in psychosis (per Positive and Negative Syndrome Scale), mood symptoms (per Young Mania Rating Scale and Hamilton Depression Rating Scale-21 items), and functioning (per Personal and Social Performance Scale) from week 1 to all time points during the 25-week treatment period (P acute exacerbation of SCA provided rapid, broad, and persistent reduction in psychotic, depressive, and manic symptoms, as well as improved functioning.

    Schriever, J; Bühlen, M; Broich, K

    2014-08-01

    For the acute treatment of the headache phase of a migraine attack, a variety of different pharmacotherapeutic treatment options exist. These range from nonspecifically acting non-opioid analgesics (e.g., paracetamol) and nonsteroidal anti-inflammatory substances (e.g., acetylsalicylic acid, ibuprofen, naproxen, diclofenac) to agents specifically interfering with the serotonin system (ergot alkaloids such as ergotamine and its derivatives, triptans). In patients with significant emesis co-occurring during an attack, additional antiemetics such as metoclopramide or domperidone may be administered. In migraine prophylaxis, largely divergent agents, e.g., β-adrenoceptor antagonists, Ca-antagonists, or anticonvulsants, are commonly used. The diversity of these compounds may help the treating physician to tailor prophylactic treatment to the patient's individual needs. The treatment success of the individual patient is difficult to predict both in acute and prophylactic migraine treatment. Apart from contraindications or associated side effects of a particular substance, the individual patient's response to treatment is therefore a major determinant in selecting the suitable medication.

    Dejan V. Radenkovic

    2016-01-01

    Full Text Available Abdominal compartment syndrome (ACS in patients with severe acute pancreatitis (SAP is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach. There remains uncertainty about the most appropriate surgical technique for the treatment of ACS in SAP. Some unresolved questions remain including medical treatment, indications, timing, and interventional techniques. This review will focus on interventional treatment of this serious condition. First line therapy is conservative treatment aiming to decrease IAP and to restore organ dysfunction. If nonoperative measures are not effective, early abdominal decompression is mandatory. Midline laparostomy seems to be method of choice. Since it carries significant morbidity we need randomized studies to establish firm advantages over other described techniques. After ACS resolves efforts should be made to achieve early primary fascia closure. Additional data are necessary to resolve uncertainties regarding ideal timing and indication for operative treatment.

    AIM: To summarize our methods and experience with interventional treatment for symptomatic acute-subacute portal vein and superior mesenteric vein thrombosis (PV-SMV) thrombosis. METHODS: Forty-six patients (30 males, 16 females,aged 17-68 years) with symptomatic acute-subacute portal and superior mesenteric vein thrombosis were accurately diagnosed with Doppler ultrasound scans, computed tomography and magnetic resonance imaging.They were treated with interventional therapy, including direct thrombolysis (26 cases through a transjugular intrahepatic portosystemic shunt; 6 through percutaneous transhepatic portal vein cannulation) and indirect thrombolysis (10 through the femoral artery to superior mesenteric artery catheterization; 4 through the radial artery to superior mesenteric artery catheterization).RESULTS: The blood reperfusion of PV-SMV was achieved completely or partially in 34 patients 3-13 d after thrombolysis. In 11 patients there was no PV-SMV blood reperfusion but the number of collateral vessels increased significantly. Symptoms in these 45 patients were improved dramatically without severe operational complications. In 1 patient, the thrombi did not respond to the interventional treatment and resulted in intestinal necrosis, which required surgical treatment.In 3 patients with interventional treatment, thrombi re-formed 1, 3 and 4 mo after treatment. In these 3 patients, indirect PV-SMV thrombolysis was performed again and was successful.CONCLUSION: Interventional treatment, including direct or indirect PV-SMV thrombolysis, is a safe and effective method for patients with symptomatic acutesubacute PV-SMV thrombosis.

    Objective:To study the myocardium-protective effect of ticagrelor combined with emergency PCI treatment of acute myocardial infarction and explore the possible molecular mechanisms. Methods:A total of 84 patients with acute myocardial infarction who received emergency PCI treatment in our hospital from February 2014 to October 2015 were selected for study and randomly divided into and ticagrelor group and clopidogrel group that received different perioperative anti-platelet therapy. Degree of myocardial cell damage, cardiac pump function as well as blood perfusion and platelet aggregation function of two groups were evaluated. Results:Before as well as 10 min and 24 h after PCI, plasma CK-MB and cTnI levels as well as maximum platelet aggregation rate and P2Y12 reaction unit of ticagrelor group were significantly lower than those of clopidogrel group, and ADP-way platelet inhibition rate were higher than those of clopidogrel group; after PCI, TIMI blood flow grade, TMP myocardial perfusion grade and LVEF of ticagrelor group were significantly higher than those of clopidogrel group, LVEDD was significantly lower than that of clopidogrel group and the number of cases with no reflow/slow flow was less than that of clopidogrel group. Conclusions:The myocardium-protective effect of ticagrelor combined with emergency PCI treatment of acute myocardial infarction is better than that of clopidogrel, and ticagrelor can enhance the anti-platelet aggregation effect to exert myocardium-protective effect.

    Oritavancin, a semisynthetic derivative of the glycopeptide antibiotic chloroeremomycin, received the US Food and Drug Administration approval for the treatment of acute bacterial skin and skin structure infections caused by susceptible Gram-positive bacteria in adults in August 2014. This novel second-generation semisynthetic lipoglycopeptide antibiotic has activity against a broad spectrum of Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate S. aureus (VISA), and vancomycin-resistant Enterococcus. Oritavancin inhibits bacterial cell wall synthesis and is rapidly bactericidal against many Gram-positive pathogens. The long half-life of this drug enables a single-dose administration. Oritavancin is not metabolized in the body, and the unchanged drug is slowly excreted by the kidneys. In two large Phase III randomized, double-blind, clinical trials, oritavancin was found to be non-inferior to vancomycin in achieving the primary composite end point in the treatment of acute Gram-positive skin and skin structure infections. Adverse effects noted were mostly mild with nausea, headache, and vomiting being the most common reported side effects. Oritavancin has emerged as another useful antimicrobial agent for treatment of acute Gram-positive skin and skin structure infections, including those caused by MRSA and VISA. PMID:26185459

    As common acute abdomen, most of acute pancreatitis(AP) are self-restricted. Only a few patients may develop into worse state with local complications or organ failures, and finally neastic acute pancreatitis (NAP). With the change of people's dietaries, cholelithiasis morbidity and popularization of wine in recent years, the number of AP patients has increased.Although people conducted enormous studies on pathogenesis of AP and brought forward many be valuable theories, yet the exact mechanism is still unclear by far. There are many therapies of AP which should be unexceptionally classified as operative therapy and non-operative therapy. With the increasing understanding of the disease in recent years, we found many defects of operation and good therapeutic effects of traditional Chinese medicine in AP. Traditional Chinese medicine as an auxiliary therapy has been generally paid close attention in clinical practices. Traditional Chinese medicine is a treasure-house of China. This article summarizes the main mechanisms of AP treatment by traditional Chinese medicine and the progress of laboratory studies. It aims to help people recognize the multiple-target treatment effects and conspicuous efficacy of traditional Chinese medicine and promote the popularization of traditional Chinese medicine in AP treatment.

    Objective:To evaluate the anti-ulcer activity and acute toxicity of Ficus religiosa (F. religiosa) leaf ethanolic extract in animal models. Methods:Anti-ulcer activity of F. religiosa ethanolic extract (250 and 500 mg/kg body weight) was studied on stress induced ulcer animal models. Ranitidine was used as standard. The anti-ulcer activity of F. religiosa was evaluated with the help of ulcer area and histopatholgical examination. Preliminary phyto-chemical screening and acute toxicity studies of F. religiosa also carried out. Results: Results showed that the extract treatments prevented ulcer area and gastric secretion in a dose-dependent manner. Administration of 2 000 mg/kg extract did not show any acute toxicity in albino mice. Preliminary phytochemical analysis identified the presence of flavonoids in the ethanolic extract of F. religiosa. Conclusions: The extract is non-toxic even at relatively high concentrations.

    Full Text Available Acute ankle injuries are among the most common injuries in emergency departments. However, a standardized examination and an evidence-based treatment are missing. Therefore, aim of this study was to systematically search the current literature, classify the evidence and develop an algorithm for diagnosis and treatment of acute ankle injuries. We systematically searched PubMed and the Cochrane Database for randomized controlled trials, meta-analysis, systematic reviews, or if applicable observational studies and classified them according to their level of evidence. According to the currently available literature, the following recommendations are given. The Ottawa Ankle/Foot Rule should be applied in order to rule out fractures, Physical examination is sufficient for diagnosing injuries to the lateral ligament complex. Classification into stable and unstable injuries is applicable and of clinical importance. The squeeze-, crossed leg- and external rotation test are indicative for injuries of the syndesmosis. Magnetic resonance imaging is recommended to verify such injuries. Stable ankle sprains have a good prognosis, while for unstable ankle sprains conservative treatment is at least as effective as operative treatment without carrying possible complications. Early functional treatment leads to the fastest recovery and the least rate of re-injury. Supervised rehabilitation reduces residual symptoms and re-injuries. Taken these recommendations into account, we here present an applicable and evidence-based step by step decision pathway for the diagnosis and treatment of acute ankle injuries, which can be implemented in any emergency department or doctor’s practice. It provides quality assurance for the patient and confidence for the attending physician.

    BACKGROUND: Common intravenous recombinant tissue plasminogen activator (IV rt-PA) exclusion criteria may substantially limit the use of thrombolysis. Preliminary data have shown that the SMART (Simplified Management of Acute stroke using Revised Treatment) criteria greatly expand patient...... eligibility by reducing thrombolysis exclusions, but they have not been assessed on a large scale. We evaluated the safety and efficacy of general adoption of SMART thrombolysis criteria to a large regional stroke network. METHODS: Retrospective analysis of consecutive patients who received IV thrombolysis...... application of SMART criteria is safe and effective. Widespread application of these criteria could substantially increase the proportion of patients who might qualify for treatment....

    Full Text Available We report a case of a 59-year-old woman who presented with worsening dyspnea which rapidly progressed to severe heart failure. Coronary arteries showed no obstruction. Supportive measures stabilized the patient’s hemodynamics. Initially intravenous solumedrol was given, but when the patient’s condition continued to deteriorate, intravenous immunoglobulin (IVIG was added to the treatment regimen and her condition improved. Studies show no benefit to using immunosuppressive agents in viral myocarditis, but benefits have been demonstrated in other etiologies. Patients presenting with acute fulminant myocarditis with unknown etiology that continue to deteriorate with aggressive heart failure treatment may benefit from steroids and IVIG.

  17. Treatment for infections complications of experimental acute radiation sickness with sulacillin, a combined antibiotic

    International Nuclear Information System (INIS)

    The therapeutic efficiency of sulacillin (combination of ampicillin antibiotic with beta-lactamase sulbactam inhibitor) used for prevention and treatment of infections complications of the acute radiation disease (ARD) is considered. It is shown that sulacillin antiinfections effect essentially exceeds the activity of ampicillin by treatment of irradiated mice infected with a beta-lactamase-producing strain of Kl pneumoniae. Inclusion of the sulacillin as a principal antibiotic into the ARD therapeutic scheme provides for the 66.6 % survival of dogs at LD90/45

    The progressive aging of the population is associated with an increase in the proportion of very old patients (greater than 75 years) hospitalized with acute myocardial infarction. The lack of evidence regarding the efficacy of most therapeutic interventions for acute myocardial infarction in these patients is leading to a significant degree of uncertainty in the cardiology community with respect to their optimal management. When aggressive treatment (defined as a therapeutic strategy designed to obtain and maintain a patent infarct-related coronary artery at an early moment) of acute myocardial infarction is considered in very old patients, three main questions should be addressed: why should we treat? Whom should we treat? And how should we treat? To answer these questions, the authors reviewed the data available in the literature as well as new data from the PPRIMM75 (Pronóstico del PRimer Infarto de Miocardio en Mayores de 75 aÃ+/-os) Registry, a large, prospective database of patients aged 75 years or older, admitted to a single coronary care unit in Madrid, Spain, for their first acute myocardial infarction during the last decade.

    Asparaginases are a cornerstone of treatment protocols for acute lymphoblastic leukemia (ALL) and are used for remission induction and intensification treatment in all pediatric regimens and in the majority of adult treatment protocols. Extensive clinical data have shown that intensive asparaginase treatment improves clinical outcomes in childhood ALL. Three asparaginase preparations are available: the native asparaginase derived from Escherichia coli (E. coli asparaginase), a pegylated form of this enzyme (PEG-asparaginase), and a product isolated from Erwinia chrysanthemi, ie, Erwinia asparaginase. Clinical hypersensitivity reactions and silent inactivation due to antibodies against E. coli asparaginase, lead to inactivation of E. coli asparaginase in up to 60% of cases. Current treatment protocols include E. coli asparaginase or PEG-asparaginase for first-line treatment of ALL. Typically, patients exhibiting sensitivity to one formulation of asparaginase are switched to another to ensure they receive the most efficacious treatment regimen possible. Erwinia asparaginase is used as a second- or third-line treatment in European and US protocols. Despite the universal inclusion of asparaginase in such treatment protocols, debate on the optimal formulation and dosage of these agents continues. This article provides an overview of available evidence for optimal use of Erwinia asparaginase in the treatment of ALL.

    We evaluated the imaging abnormalities of the brain observed during and after treatment of acute childhood lymphoblastic leukemia. The study group consisted of 30 patients (male : female=19 : 11 ; mean age, 64 months) with acute childhood lymphoblastic leukemia during the previous ten-year period who had undergone prophylaxis of the central nervous system. Irrespective of the CNS symptoms, base-line study of the brain involving CT and follow-up CT or MRI was undertaken more than once. We retrospectively evaluated the imaging findings, methods of treatment, associated CNS symptoms, and the interval between diagnosis and the time at which brain abnormalities were revealed by imaging studies. In 15 (50% ; male : female=9 : 6 ; mean age, 77 months) of 30 patients, brain abnormalities that included brain atrophy (n=9), cerebral infarctions (n=4), intracranial hemorrhage (n=1), mineralizing microangiopathy (n=2), and periventricular leukomalacia (n=3) were seen on follow-up CT or MR images. In four of nine patients with brain atrophy, imaging abnormalities such as periventricular leukomalacia (n=2), infarction (n=1) and microangiopathy (n=1) were demonstrated. Fourteen of the 15 patients underwent similar treatment ; the one excluded had leukemic cells in the CSF. Six patients had CNS symptoms. In the 15 patients with abnormal brain imaging findings, the interval between diagnosis and the demonstration of brain abnormalities was between one month and four years. After the cessation of treatment, imaging abnormalities remained in all patients except one with brain atrophy. Various imaging abnormalities of the brain may be seen during and after the treatment of acute childhood lymphoblastic leukemia and persist for a long time. In children with this condition, the assessment of brain abnormalities requires follow-up study of the brain.

    Full Text Available Abstract Background In order to assist health service planning, understanding factors that influence higher trauma treatment costs is essential. The majority of trauma costing research reports the cost of trauma from the perspective of the receiving hospital. There has been no comprehensive synthesis and little assessment of the drivers of cost variation, such as country, trauma, subgroups and methods. The aim of this review is to provide a synthesis of research reporting the trauma treatment costs and factors associated with higher treatment costs in high income countries. Methods A systematic search for articles relating to the cost of acute trauma care was performed and included studies reporting injury severity scores (ISS, per patient cost/charge estimates; and costing methods. Cost and charge values were indexed to 2011 cost equivalents and converted to US dollars using purchasing power parities. Results A total of twenty-seven studies were reviewed. Eighty-one percent of these studies were conducted in high income countries including USA, Australia, Europe and UK. Studies either reported a cost (74.1% or charge estimate (25.9% for the acute treatment of trauma. Across studies, the median per patient cost of acute trauma treatment was $22,448 (IQR: $11,819-$33,701. However, there was variability in costing methods used with 18% of studies providing comprehensive cost methods. Sixty-three percent of studies reported cost or charge items incorporated in their cost analysis and 52% reported items excluded in their analysis. In all publications reviewed, predictors of cost included Injury Severity Score (ISS, surgical intervention, hospital and intensive care, length of stay, polytrauma and age. Conclusion The acute treatment cost of trauma is higher than other disease groups. Research has been largely conducted in high income countries and variability exists in reporting costing methods as well as the actual costs. Patient populations studied

    Acute ethanol administration increases potent GABAergic neuroactive steroids, specifically (3α,5α)-3-hydroxypregnan-20-one (3α,5α-THP) and (3α,5α)-3,21-dihydroxypregnan-20-one. In addition, neuroactive steroids contribute to ethanol actions. Chronic ethanol exposure results in tolerance to many effects of ethanol, including ethanol-induced increases in neuroactive steroid levels. To determine the mechanisms of tolerance to ethanol-induced increases in neuroactive steroids, we investigated cri...

The diagnosis of acute hydrops was based on clinical and functional evaluations including optical coherent tomography (OCT. A part of diseased cornea was removed and examined under a light microscope. These studies revealed morphological changes in almost all corneal layers. OCT and histology demonstrated that PK was indicated to this patient. Recent literature data on the epidemiology and pathogenesis of acute hydrops are presented. This rare disease results from tears in the Descemet’s membrane that allow aqueous humor to enter the stroma. Current treatment is aimed to suppress corneal inflammation, restore endothelium and Descemet’s membrane integrity and drain stromal cysts to optimize cornea healing. In this case, subtotal PK was performed due to the significant corneal thinning and a high risk of its melting. «Material for corneal graft» (iLab, Moscow, Russia was used as a donor material.

    Acute ischemic stroke is a common disease associated with high mortality and significant long-term disability. Treatment options for acute ischemic stroke continue to evolve and include pharmaceutical and mechanical therapies. With the recent US Food and Drug Administration approval of a new device for mechanical thrombectomy, the options available for treatment of acute ischemic stroke have been expanded. Thrombolytic therapy is generally given intravenously in the first 3 h and up to 6 h via the intraarterial route for pharmacological clot disruption. The maximum time-frame for mechanical thrombectomy devices has yet to be determined. A 78-year-old female presented to the emergency room with a dense right hemiparesis, leftward gaze preference and dense global aphasia. Eight hours after symptom onset, left carotid angiography confirmed a left internal carotid artery terminus occlusion. A single pass was made through the clot with an X6 Merci Retriever device. After a single pass, the vessel was reopened and normal flow in the left internal carotid artery was demonstrated. At the time of discharge, her neurological deficits had improved significantly. Furthermore, the final infarct area, as demonstrated on magnetic resonance imaging, was probably much smaller than it would have been if the vessel had not been recanalized. (orig.)

  9. Thrombolytic treatment for acute ischemic cerebral stroke: intraarterial urokinase infusion vs. intravenous heparin and urokinase infusion

    International Nuclear Information System (INIS)

    To evaluate the efficacy and limitation of intra-arterial urokinase (IAUK) infusion for treatment of acute cerebral stroke. Twenty-seven acute cerebral stroke patients treated with IAUK infusion within six hours of stroke onset were reviewed. All patients showed normal initial brain findings on CT. In 21 patients, urokinase(5-15 x 105IU) was administered through a microcatheter placed into or proximal to occluded segment. Mechanical disruption of thrombus by guidewire was performed in 17 patients. Angiographic and clinical responses and complications after IAUK infusion, were evaluated and the results were compared with those of intravenous heparin(N=19) and urokinase infusion(N=19). Complete or partial angiographic recanalization of occluded segment was found in 18 patients (67%), and neurologic improvement was followed in 14 patients(52%). The degree of improvement on the stroke scale score after IAUK infusion was statistically more significant(p<0.05) than that shown after intravenous heparin and urokinase infusion. Complications after IAUK infusion were large(15%) and small amount intracerebral hemorrhage(15%), contrast leakage into brain parenchyma(11%), and gastrointestinal bleeding(4%). Between the IAVK and the intravenous urokinase infusion group, differences in extent and types of complications were statistically insignificant, but were significantly higher in those two groups than in the intravenous heparin infusion group. IAUK infusion may be effective for the treatment of acute cerebral stroke

    Zebrafish have been successfully employed in the study of the behavioural and biological effects of ethanol. Like in mammals, low to moderate doses of ethanol induce motor hyperactivity in zebrafish, an effect that has been attributed to the activation of the dopaminergic system. Acute ethanol exposure increases dopamine (DA) in the zebrafish brain, and it has been suggested that tyrosine hydroxylase, the rate-limiting enzyme of DA synthesis, may be activated in response to ethanol via phosphorylation. The current study employed tetrahydropapaveroline (THP), a selective inhibitor of phosphorylated tyrosine hydroxylase, for the first time, in zebrafish. We treated zebrafish with a THP dose that did not alter baseline motor responses to examine whether it can attenuate or abolish the effects of acute exposure to alcohol (ethanol) on motor activity, on levels of DA, and on levels of dopamine's metabolite 3,4-dihydroxyphenylacetic acid (DOPAC). We found that 60-minute exposure to 1% alcohol induced motor hyperactivity and an increase in brain DA. Both of these effects were attenuated by pre-treatment with THP. However, no differences in DOPAC levels were found among the treatment groups. These findings suggest that tyrosine hydroxylase is activated via phosphorylation to increase DA synthesis during alcohol exposure in zebrafish, and this partially mediates alcohol's locomotor stimulant effects. Future studies will investigate other potential candidates in the molecular pathway to further decipher the neurobiological mechanism that underlies the stimulatory properties of this popular psychoactive drug.

    Full Text Available OBJECTIVE: Single voxel proton magnetic resonance spectroscopy (MRS can be used to monitor changes in brain inflammation and neuronal integrity associated with HIV infection and its treatments. We used MRS to measure brain changes during the first weeks following HIV infection and in response to antiretroviral therapy (ART. METHODS: Brain metabolite levels of N-acetyl aspartate (NAA, choline (tCHO, creatine (CR, myoinositol (MI, and glutamate and glutamine (GLX were measured in acute HIV subjects (n = 31 and compared to chronic HIV+individuals (n = 26 and HIV negative control subjects (n = 10 from Bangkok, Thailand. Metabolites were measured in frontal gray matter (FGM, frontal white matter (FWM, occipital gray matter (OGM, and basal ganglia (BG. Repeat measures were obtained in 17 acute subjects 1, 3 and 6 months following initiation of ART. RESULTS: After adjustment for age we identified elevated BG tCHO/CR in acute HIV cases at baseline (median 14 days after HIV infection compared to control (p = 0.0014, as well as chronic subjects (p = 0.0023. A similar tCHO/CR elevation was noted in OGM; no other metabolite abnormalities were seen between acute and control subjects. Mixed longitudinal models revealed resolution of BG tCHO/CR elevation after ART (p = 0.022 with tCHO/CR similar to control subjects at 6 months. INTERPRETATION: We detected cellular inflammation in the absence of measurable neuronal injury within the first month of HIV infection, and normalization of this inflammation following acutely administered ART. Our findings suggest that early ART may be neuroprotective in HIV infection by mitigating processes leading to CNS injury.

Eight (88.9% patients, including two Philadelphia chromosome-positive ALL patients, achieved a complete remission. Furthermore, the evaluable patients have benefited from allo-HSCT after response to this reinduction treatment. We conclude that bortezomib-based chemotherapy was highly effective for adults with refractory/relapsed ALL before allo-HSCT. Therefore, this regimen deserves a larger series within prospective trials to confirm these results. Keywords: acute lymphoblastic leukemia, refractory, relapsed, bortezomib

    2007-07-01

    Full Text Available Acute necrotizing pancreatitis is still a fatal disease. Pancreatic necrosis might be, in part, a result of infarction due to ischemia with vasospasm and an increase in intravascular coagulability. Synthetic antiproteases have a broad inhibitory action on pancreatic enzymes, the coagulation system, the complement system and the production of proinflammatory cytokines. Therefore, antiproteases have been expected to prevent necrotic changes in the pancreas and to reduce the mortality rate. However, the clinical efficacy of antiproteases is still a matter of controversy. Unfortunately, an antiprotease cannot easily reach the pancreas when administered intravenously because of its pharmacokinetic characteristics and impaired microcirculation. Administration through a catheter placed in one of the arteries which supplies the inflamed area of the pancreas, dramatically increases the concentration of the antiprotease in the pancreas. Clinical studies of continuous regional arterial infusion of a protease inhibitor have been conducted in Japan and have demonstrated the possible therapeutic efficacy of the new treatment in severe acute pancreatitis.

The purpose of this study was to assess the additional bronchodilating effect of increasing doses of salbutamol during acute and chronic treatment with formoterol in patients with COPD.Methods: Ten patients with COPD underwent a dose-response curve to salbutamol (until 800 µg of cumulative dose after a 1-week washout (baseline, 8 hours after the first administration of formoterol 12 µg (day 1, and after a 12-week and 24-week period of treatment with formoterol (12 µg twice daily by dry powder inhaler. Peak expiratory flow, forced expiratory volume in one second (FEV1, forced vital capacity, and inspiratory capacity were measured at the different periods of treatment and at different steps of the dose-response curve.Results: Despite acute or chronic administration of formoterol, maximal values of peak expiratory flow, FEV1, and forced vital capacity after 800 µg of salbutamol were unchanged compared with baseline. The baseline FEV1 dose-response curve was steeper than that at day 1, week 12, or week 24 (P < 0.0001. Within each dose-response curve, FEV1 was different only at baseline and at day 1 (P < 0.001, when FEV1 was still greater at 800 µg than at 0 µg (P < 0.02. In contrast, the forced vital capacity dose-response curves were similar at the different periods, while within each dose-response curve, forced vital capacity was different in all instances (P < 0.001, always being higher at 800 µg than at 0 µg (P < 0.05.Conclusion: In patients with stable COPD, the maximal effect

    Objective: To observe the therapeutic effect of acupuncture plus manual reposition for treatment of acute lumbar vertebral articular dyskinesia for choosing a better remedy. Methods: 66 cases of acute lumbar vertebral articular dyskinesia were randomly divided into acupuncture plus manual reposition group (treatment group, n= 33) and routine manual reposition group (control group, n = 33). Yaotong-point was punctured, when, the patient was asked to move his or her waist simultaneously. Results: After one session of treatment, of the two 33 cases in treatment and control groups, 28 (84.85%) and20 (60.61%) were cured, 4 (12.12%) and 9 (27.27%) were improved, and 1 (3.03%) and 4 (12.12%) failed in the treatment. The therapeutic effect of treatment group was significantly superior to that of control group ( P< 0.05). Conclusion: Acupuncture combined with manual reposition is apparently superior to simple routine manual reposition in relieving acute lumbar vertebral articular dyskinesia.

    Rapid eye movement (REM) sleep deprivation (SD) is implicated in impairment of spatial learning and memory and hippocampal long-term potentiation (LTP). An increase in nicotine consumption among habitual smokers and initiation of tobacco use by nonsmokers was observed during SD. Although nicotine treatment was reported to attenuate the impairment of learning and memory and LTP associated with several mental disorders, the effect of nicotine on SD-induced learning and memory impairment has not been studied. Modified multiple platform paradigm was used to induce SD for 24 or 48 h during which rats were injected with saline or nicotine (1 mg kg(-1) s.c.) twice a day. In the radial arm water maze (RAWM) task, 24- or 48-h SD significantly impaired learning and short-term memory. In addition, extracellular recordings from CA1 and dentate gyrus (DG) regions of the hippocampus in urethane anesthetized rats showed a significant impairment of LTP after 24- and 48-h SD. Treatment of normal rats with nicotine for 24 or 48 h did not enhance spatial learning and memory or affect magnitude of LTP in the CA1 and DG regions. However, concurrent, acute treatment of rats with nicotine significantly attenuated SD-induced impairment of learning and STM and prevented SD-induced impairment of LTP in the CA1 and DG regions. These results show that acute nicotine treatment prevented the deleterious effect of sleep loss on cognitive abilities and synaptic plasticity.

    Full Text Available Introduction. During chemotherapy of acute lymphoblastic leukaemia (ALL, children sometimes exhibit neurological disturbances. Chemiotherapeutic regimens include methotrexate, administered either intravenously or via intrathecal route. Although multiple drugs are used in addition to methotrexate, the acute neurotoxicity reported in patients is usually attributed to methotrexate. The acute neurotoxicity usually results in stroke-like symptoms such as aphasia, weakness, sensory deficits, ataxia and seizures. Outline of Cases. From 2002 until January 2008, 32 children with ALL were diagnosed and treated at the Children's Hospital in Niš. The patients' age ranged from 1.5 to 16 years. They were treated in accordance with the protocol ALL IC-BFM 2002 (ALL Intercontinental Berlin Frankfurt M'nster 2002. Two of the patients (6.25% exhibited neurotoxicity. After the occurrence of neurological symptoms, the patients were ophthalmologically and neurologically examined. In addition, the magnetic resonance (MR imaging, computerized tomography and electroencephalography were applied. The paper presents two patients, aged 9 and 15 years respectively, who exhibited acute neurotoxicity - methotrexate encephalopathy during ALL treatment. Both patients had tonic-clonic seizures and neurological symptoms in the course of the induction therapy. Neurotoxicity occurred 7 days after the third, and 3 days after the fourth intrathecal methotrexate therapy. MR images confirmed multi-focal morphological changes of brain density in one of the patients, while the other patient had normal CT reading. Even though the development significantly differed, the changes were reversible in both patients. Conclusion. The neurotoxicity in patients with ALL can be combined with significant structural changes of the brain, but also morphological changes can be absent. Several questions concerning aetiology and treatment of neurological events are raised.

    Full Text Available Abhinav Deol, Voravit Ratanatharathorn, Joseph P UbertiDepartment of Oncology, Blood and Marrow Stem Cell Transplant Program, Barbara Ann Karmanos Cancer Institute, Wayne State University School of Medicine, Detroit, MI, USAAbstract: Acute graft-versus-host disease (aGVHD is an immunologically mediated inflammatory reaction, which continues to be a major cause of morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplant. Although the occurrence and severity of this disease may be devastating, there is a proven immunologically mediated antitumor activity that accompanies the disease process, which has a beneficial effect on outcome. Animal models of graft-versus-host disease (GVHD have given us a conceptual model that has allowed a better understanding of the pathophysiology and offers a framework for understanding the complex interactions between antigen-presenting cells, donor T-cells, and cytokines in the development of aGVHD. It has also given us a model that allows testing of various strategies for prevention and treatment. New, innovative approaches for treatment and prevention of aGVHD including better donor selection with the use of sophisticated human leukocyte antigen typing, use of T-cell depletion, reduced-intensity transplant regimens, and improved pharmacologic immunosuppression have improved outcomes by decreasing the incidence and severity of aGVHD. However, the limitation of these strategies is that effective treatment and prevention of aGVHD is often accompanied by a concomitant rise in relapses, graft failure and infections, and ultimately no improvement in overall survival. Investigators are working on understanding the difference between GVHD and graft versus tumor effect, as this would be the key in improving outcomes for our patients. In this review, we will discuss the pathophysiology of aGVHD along with the preventative and treatment strategies.Keywords: acute GVHD, GVHD, acute graft

In this study, pedobarographic assessments of surgical and conservative treatments were compared.Material and methods: A prospective assessment was made of 16 patients (eight surgical, eight conservative and eight healthy controls using a plantar pressure measurement system. Biomechanical gait parameters were obtained using the Footscan dynamic gait analysis system. Kruskal–Wallis and Mann–Whitney U-tests were used for the evaluation of data.Results: Nineteen males and five females were assessed, with an average age of 42.0±11.9 years. Follow-up was completed in 16 patients. No statistically significant difference was determined between the two treatment groups with regard to the gait analysis, but a difference was observed with the control group (P<0.001. All patients were able to resume their prior activities after 6 months and regained normal ranges of motion, with a high rate of satisfaction. Most of the patients (75% were able to return to their pre-injury level of activities.Conclusion: Satisfactory results were obtained through conservative treatment of acute ruptures of the Achilles tendon. No significant differences or complications were observed in the group managed conservatively versus the group treated surgically. Further studies including 3D gait analyses and tendon biomechanical research are required to further investigate this issue.Keywords: Achilles tendon, acute rupture, pedobarographic analysis

    Full Text Available Abstract Background Previous research has provided evidence that socioeconomic status has an impact on invasive treatments use after acute myocardial infarction. In this paper, we compare the socioeconomic inequality in the use of high-technology diagnosis and treatment after acute myocardial infarction between the US, Quebec and Belgium paying special attention to financial incentives and regulations as explanatory factors. Methods We examined hospital-discharge abstracts for all patients older than 65 who were admitted to hospitals during the 1993–1998 period in the US, Quebec and Belgium with a primary diagnosis of acute myocardial infarction. Patients' income data were imputed from the median incomes of their residential area. For each country, we compared the risk-adjusted probability of undergoing each procedure between socioeconomic categories measured by the patient's area median income. Results Our findings indicate that income-related inequality exists in the use of high-technology treatment and diagnosis techniques that is not justified by differences in patients' health characteristics. Those inequalities are largely explained, in the US and Quebec, by inequalities in distances to hospitals with on-site cardiac facilities. However, in both Belgium and the US, inequalities persist among patients admitted to hospitals with on-site cardiac facilities, rejecting the hospital location effect as the single explanation for inequalities. Meanwhile, inequality levels diverge across countries (higher in the US and in Belgium, extremely low in Quebec. Conclusion The findings support the hypothesis that income-related inequality in treatment for AMI exists and is likely to be affected by a country's system of health care.

    Full Text Available Abstract Deaths after percutaneous ethanol injection (PEI into hepatocellular carcinoma (HCC may occur within a few hours to a few days following the procedure because of hemoperitoneum and haemorrhage from oesophageal varices or hepatic insufficiency. Pancreatitis has been recently reported as a rare lethal complication of intra-arterial PEI, another modality for treating HCCs. In this minireview, we analyze the literature concerning the development of acute pancreatitis after PEI. Pathogenesis of pancreatitis from opioids and ethanol is also addressed. Treatment with opioids to reduce the patient's abdominal pain after PEI in combination with the PEI itself may lead to direct toxic effects, thus favouring the development of pancreatitis.

    This symposium focused on functional alterations in the mesolimbic dopamine system during the abstinence phase after chronic alcohol intake. Mark Brodie first described his recordings from midbrain slices prepared after chronic alcohol treatment in vivo by daily injection in C57BL/6J mice. No changes were found in the baseline firing frequency of dopaminergic neurones in the VTA (ventral tegmental area), but the excitation produced in these neurones by an acute ethanol challenge was significantly increased in neurons from ethanol-treated mice compared with those from the saline-treated controls. There was also a significant decrease in the inhibitory response to GABA by the dopamine neurones following the chronic ethanol treatment. These data suggest that the timing pattern and mode of ethanol administration may determine the types of changes observed in dopaminergic reward area neurons. Annalisa Muntoni lectured on the relationship between electrophysiological and biochemical in vivo evidence supporting a reduction in tonic activity of dopamine neurons projecting to the nucleus accumbens at various times after suspension of chronic ethanol treatment and morphological changes affecting dopamine neurons in rat VTA. Hilary J. Little then described changes in dopaminergic neurone function in the VTA during the abstinence phase. Decreases in baseline firing were seen at 6 days after withdrawal of mice from chronic ethanol treatment but were not apparent after 2 months abstinence. Increases in the affinity of D1 receptors in the striatum, but not in the cerebral cortex, were seen however up to 2 months after withdrawal. Scott Steffensen then described his studies recording in vivo from GABA containing neurones in the VTA in freely moving rats. Chronic ethanol administration enhanced the baseline activity of these neurones and resulted in tolerance to the inhibition by ethanol of these neurones. His results demonstrated selective adaptive circuit responses within the VTA

    Extensive evidence indicates that ethanol (alcohol) has immunomodulatory properties. Many of its effects on innate immune response are dose-dependent, with acute or moderate use associated with attenuated inflammatory responses, and heavy ethanol consumption linked with augmentation of inflammation. Ethanol may modify innate immunity via functional alterations of the cells of the innate immune system. Mounting evidence indicates that ethanol can diversely affect antigen recognition and intrac...

    AIM: To explore the feasibility of computed tomography (CT)-guided percutaneous ethanol injection (PEI) using a disposable curved needle for treatment of malignant liver neoplasms and their metastases in retroperitoneal lymph nodes.METHODS: CT-guided PEI was conducted using a disposable curved needle in 26 malignant liver tumors smaller than 5 cm in diameter and 5 lymph node metastases of liver cancer in the retroperitoneal space. The disposable curved needle was composed of a straight trocar (21G) and stylet, a disposable curved tip (25 G) and a fine stylet. For the tumors found in deep sites and difficult to reach, or for hepatic masses inaccessible to the injection using a straight needle because of portal vein and bile ducts, the straight trocar was used at first to reach the side of the tumor. Then, the disposable curved needle was used via the trocar. When the needle reached the tumor center, appropriate amount of ethanol was injected. For relatively large malignant liver tumors,multi-point injection was carried out for a better distribution of the ethanol injected throughout the masses. The curved needle was also used for treatment of the metastasis in retroperitoneal lymph nodes blocked by blood vessels and inaccessible by the straight needle.RESULTS: All of the 26 liver tumors received 2 or more times of successful PEI, through which ethanol was distributed throughout the whole tumor mass. Effect of the treatment was monitored by contrast-enhanced multi-phase CT and magnetic resonance imaging (MRI) examinations three months later. Of the 18 lesions whose diameters were smaller than 3 cm, the necrotic change across the whole mass and that in most areas were observed in 15 and 3 tumors,respectively. Among the 8 tumors sizing up to 3 cm, 5 were completely necrotic and 3 largely necrotic. Levels of tumor seromarkers were significantly reduced in some of the cases.In 5 patients with metastases of liver cancer in retroperitoneal lymph nodes who received 1 to 3

    Background In 2008, infants in some areas of China suffered from stones of the urinary system which were caused by melamine-contaminated milk formula. Most of the infants were asymptomatic, and a few suffered from acute renal failure induced by urinary obstruction by stones. This study aimed to assess the significance of blood purification therapy in treatment of infants with acute obstructive oligo-anuric renal failure. Corrective perception, timely diagnosis, and active treatment of this complex disease are critical factors that guarantee a quick recovery of renal function of infants and help them to prevent multiple organ system failure.Methods Thirteen infants with acute renal failure induced by urinary multiple obstruction caused by melamine-containing stones who had been admitted to Beijing Children's Hospital Affiliated to Capital Medical University in 2008 were investigated for the epidemiological characteristics, image features and indications of dialysis. All these infants were treated with dialysis. The efficacy of dialysis was compared with that of two control groups treated with cystoscopic retrograde catheterization into the ureter and medical treatment for the recovery of renal function.Results The 13 infants with life-threatening complications treated with dialysis showed a blood urea nitrogen (BUN) level of (30.9±7.9) mmol/L and a creatinine (Cr) level of (572+173) pmol/L. Of these infants, 8 were treated with peritoneal dialysis (PD), and 5 with hemodialysis (HD). Ten infants recovered to urinate 24-72 hours after dialysis and 3 infants with persistent ureteral obstruction were further treated with cystoscopic retrograde catheterization into the ureter for drainage, and urination resumed soon after the operation. The average time of PD and HD were (2.1±0.8) days and (1.2±0.4) days, respectively. The total average time of PD and HD dialysis was (1.77±0.83) days. The recovery time of renal function of infants after dialysis was (3.08±1.20) days

    2006-12-01

    In this study we analysed the outcome of computer-assisted therapy (CAT) for anomia on eight acute aphasic patients. Since therapy for anomia generally leads to an item-specific effect, the aim of the present study was to investigate whether it is possible to enhance recovery from anomia by increasing the number of treated items. Two periods of five daily written-naming CAT sessions were compared: In one period the CAT included one set of 48 words (single list) and in the other period a double list of 96 items was treated. Seven out of eight patients improved in naming performance for treated items. Overall gains were superior after practising the double list, despite fewer item repetitions. These results suggest that the size of the effect of therapy for anomia depends more on the number of treated items than on the number of repetitions per item. The integration of these results within the framework of studies on intensity is discussed.

    Abstract Sudden sensorineural hearing loss (SSHL) is an otological emergency defined as a rapid hearing loss, seriously affects patient's social life. To data, no study has reported the treatment by acupuncture alone in the acute phase. In this report, Acupuncture and Moxibustion therapy of excitation-focus transfer is outlined. The patient was a 26-year-old young woman who had an SSHL coupled with ear fullness. The patient had no past medical history, but she had undergone variable emotions and had a history of excessive noise exposure. The patient refused to receive any medicine especially steroids and hyperbaric oxygen therapy. She just only received acupuncture treatment. Her symptoms and outcome measurements were improved every week and completely recovered after the last week. Even though the article presents a single case and is based on self-reports, there are very clear trends on how patients with SSHL responded to acupuncture treatments. PMID:27368045

    Continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) are frequently used inhospital for treating respiratory failure, especially in treatment of acute cardiogenic pulmonary edema and exacerbation of chronic obstructive pulmonary disease. Early initiation of treatment...... is important for success and introduction already in the prehospital setting may be beneficial. Our goal was to assess the evidence for an effect of prehospital CPAP or NIV as a supplement to standard medical treatment alone on the following outcome measures; mortality, hospital length of stay, intensive care...... examine prehospital CPAP. Of these, only one small, randomized controlled trial shows a reduced mortality rate and a reduced intubation rate with supplemental CPAP. The other three studies have neutral findings, but in two of these a trend toward lower intubation rate is found. The effect of supplemental...

    More than 800,000 people in North America suffer a stroke each year, with ischemic stroke making up the majority of these cases. The outcomes of ischemic stroke range from complete functional and cognitive recovery to severe disability and death; outcome is strongly associated with timely reperfusion treatment. Historically, ischemic stroke has been treated with intravenous thrombolytic agents with moderate success. However, five recently published positive trials have established the efficacy of endovascular treatment in acute ischemic stroke. In this review, we will discuss the history of stroke treatments moving from various intravenous thrombolytic drugs to intra-arterial thrombolysis, early mechanical thrombectomy devices, and finally modern endovascular devices. Early endovascular therapy failures, recent successes, and implications for current ischemic stroke management and future research directions are discussed. PMID:27021771

  18. Induction of experimental acute ulcerative colitis in rats by administration of dextran sulfate sodium at low concentration followed by intracolonic administration of 30% ethanol

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Several models of experimental ulcerative colitis have been reported previously. However, none of these models showed the optimum characteristics. Although dextran sulfate sodium-induced colitis results in inflammation resembling ulcerative colitis, an obvious obstacle is that dextran sulfate sodium is very expensive. The aim of this study was to develop an inexpensive model of colitis in rats. Sprague-Dawley rats were treated with 2% dextran sulfate sodium in drinking water for 3 d followed by an intracolonic administration of 30% ethanol. The administration of 2% dextran sulfate sodium followed by 30% ethanol induced significant weight loss, diarrhea and hematochezia in rats. Severe ulceration and inflammation of the distal part of rat colon were developed rapidly. Histological examination showed increased infiltration of polymorphonuclear leukocytes,lymphocytes and existence of cryptic abscesses and dysplasia. The model induced by dextran sulfate sodium at lower concentration followed by 30% ethanol is characterized by a clinical course, localization of the lesions and histopathological features similar to human ulcerative colitis and fulfills the criteria set out at the beginning of this study.

    AIM: To investigate the efficacy of topical application of 0.5% nifedipine ointment in healing acute anal fissue and preventing its progress to chronicity.METHODS: Thirty-one patients (10 males, 21 females)with acute anal fissure from September 1999 to January 2005 were treated topically with 0.5% nifedipine ointment (t.i.d.) for 8 wk. The patients were encouraged to follow a high-fiber diet and assessed at 2, 4 and 8wk post-treatment. The healing of fissure and any side effects were recorded. The patients were subsequently followed up in the outpatient clinic for one year and contacted by phone every three months thereafter,while they were encouraged to come back if symptoms recurred.RESULTS: Twenty-seven of the 31 patients completed the 8-wk treatment course, of them 23 (85.2%)achieved a complete remission indicated by resolution of symptoms and healing of fissure. Of the remaining four unhealed patients (14.8%), 2 opted to undergo lateral sphincterotomy and the other 2 to continue therapy for four additional weeks, resulting in healing of fissure. All the 25 patients with complete remission had a mean follow-up of 22.9 ± 14 (range 6-52) mo. Recurrence of symptoms occurred in four of these 25 patients (16%)who were successfully treated with an additional 4-wk course of 0.5% nifedipine ointment. Two of the 27 (7.4%)patients who completed the 8-wk treatment presented with moderate headache as a side effect of nifedipine.CONCLUSION: Topical 0.5% nifedipine ointment, used as an agent in chemical sphincterotomy, appears to offer a significant healing rate for acute anal fissure and might prevent its evolution to chronicity.

    Recent progress in the treatment of primary headaches has made available specific, effective and safe medications for these disorders, which are widely spread among the general population. One of the negative consequences of this undoubtedly positive progress is the risk of drug-drug interactions. This review is the first in a two-part series on pharmacokinetic drug-drug interactions of headache medications. Part I addresses acute treatments. Part II focuses on prophylactic treatments. The overall aim of this series is to increase the awareness of physicians, either primary care providers or specialists, regarding this topic. Pharmacokinetic drug-drug interactions of major severity involving acute medications are a minority among those reported in literature. The main drug combinations to avoid are: i) NSAIDs plus drugs with a narrow therapeutic range (i.e., digoxin, methotrexate, etc.); ii) sumatriptan, rizatriptan or zolmitriptan plus monoamine oxidase inhibitors; iii) substrates and inhibitors of CYP2D6 (i.e., chlorpromazine, metoclopramide, etc.) and -3A4 (i.e., ergot derivatives, eletriptan, etc.), as well as other substrates or inhibitors of the same CYP isoenzymes. The risk of having clinically significant pharmacokinetic drug-drug interactions seems to be limited in patients with low frequency headaches, but could be higher in chronic headache sufferers with medication overuse.
