    The aim of this study was to evaluate possible beneficial effects of treatment with thiamine or benfotiamine in an animal model of acute ethanol intoxication. Thirty male Wistar rats were separated at random into three groups of 10 animals each: Ethanol (E), Ethanol treated with thiamine (T) and Ethanol treated with benfotiamine (BE). Rats were gavaged with single dose of ethanol (5g/kg, 40% v:v). After 30min of ethanol gavage the animals were treated with thiamine or benfotiamine. Six hours after first gavage, the animals were euthanized and blood and liver samples were collected for ethanol and oxidative stress biomarkers quantification. Serum ethanol levels were higher in animals treated with thiamine or benfotiamine while hepatic alcohol levels were higher in animals of the group treated with benfotiamine comparing to controls or thiamine treated groups. The lipid peroxidation biomarkers were diminished for the groups treated with thiamine or benfotiamine comparing to E animals. Concerning protein oxidative damage parameters, they were enhanced for animals treated with benfotiamine in relation to other groups. In conclusion, the treatment with thiamine or benfotiamine even 30min after the massive dose of ethanol has proven to be beneficial against liver damage. Improved results were obtained with benfotiamine in relation to oxidative damage from aqueous compartments. Copyright © 2016 Elsevier Inc. All rights reserved.

    Mass or cluster methanol poisonings are frequently reported from around the world. The comparative effectiveness of ethanol and fomepizole as antidotes for methanol poisoning is unknown due to the difficulty of performing a randomized controlled trial. During an outbreak of mass poisonings in the Czech Republic in 2012-2014, we compared the effects of antidotes on the frequency of health sequelae and mortality. The study was designed as a cross-sectional case series and quasi-case-control study. Patients with a diagnosis of methanol poisoning on admission to hospitals were identified for the study. Diagnosis was established when (i) a history of recent ingestion of illicit spirits was available and serum methanol was higher than 6.2 mmol/L (20 mg/dL), or (ii) there was a history/clinical suspicion of methanol poisoning, and serum methanol was above the limit of detection with at least two of the following: pH poisoning and other key parameters, was selected. Data were obtained from 100 hospitalized patients with confirmed poisoning: 25 patients treated with fomepizole were compared with 68 patients receiving ethanol (seven patients did not receive any antidote). More severely acidotic (p 12 h; p = 0.028) patients received fomepizole more often than ethanol, as reflected in the higher number of fomepizole-treated patients being intubated (p = 0.009). No association was found between the type of antidote and the survival in either the case series (p = 0.205) or the quasi-control groups (p = 0.705) in which patients were very closely matched to minimize confounding by allocation. In the multivariate analysis, positive serum ethanol (odds ratio [OR], 10.8; 95% confidence interval [CI], 2.9-39.9) and arterial blood pH (OR, 3.7; 95% CI, 1.3-10.5) on admission were the only independent variables for the survival. The median intensive care unit length of stay was 6 (range, 2-22) days in the fomepizole group and 4 (range, 1-33) days in the ethanol group (p = 0.131). There

    Full Text Available Individual differences in initial sensitivity to ethanol are strongly related to the heritable risk of alcoholism in humans. To elucidate key molecular networks that modulate ethanol sensitivity we performed the first systems genetics analysis of ethanol-responsive gene expression in brain regions of the mesocorticolimbic reward circuit (prefrontal cortex, nucleus accumbens, and ventral midbrain across a highly diverse family of 27 isogenic mouse strains (BXD panel before and after treatment with ethanol.Acute ethanol altered the expression of ~2,750 genes in one or more regions and 400 transcripts were jointly modulated in all three. Ethanol-responsive gene networks were extracted with a powerful graph theoretical method that efficiently summarized ethanol's effects. These networks correlated with acute behavioral responses to ethanol and other drugs of abuse. As predicted, networks were heavily populated by genes controlling synaptic transmission and neuroplasticity. Several of the most densely interconnected network hubs, including Kcnma1 and Gsk3β, are known to influence behavioral or physiological responses to ethanol, validating our overall approach. Other major hub genes like Grm3, Pten and Nrg3 represent novel targets of ethanol effects. Networks were under strong genetic control by variants that we mapped to a small number of chromosomal loci. Using a novel combination of genetic, bioinformatic and network-based approaches, we identified high priority cis-regulatory candidate genes, including Scn1b, Gria1, Sncb and Nell2.The ethanol-responsive gene networks identified here represent a previously uncharacterized intermediate phenotype between DNA variation and ethanol sensitivity in mice. Networks involved in synaptic transmission were strongly regulated by ethanol and could contribute to behavioral plasticity seen with chronic ethanol. Our novel finding that hub genes and a small number of loci exert major influence over the ethanol

Authors examined 93 patients stratified into three groups (acute poisoning with ethanol in patients with chronic alcoholism, without chronic alcoholism and those treated with reamberin). The presence of chronic alcoholism significantly augmented metabolic disturbances and influenced the disturbance of oxygen-transport function and free-radical processes in patients with acute intoxication with ethanol. Using of reamberin in the complex intensive therapy led to the decrease in metabolic disorders, which improved the clinical course of acute poisoning with ethanol in patients with chronic alcoholism.

    In the present study, we examined whether Acer okamotoanum (A. okamotoanum) sap decreased the serum alcohol and acetaldehyde levels after acute ethanol treatment in a rat model. Male rats were orally administered 25, 50 or 100% A. okamotoanum sap 30 min prior to oral challenge with 3 ml of ethanol (15 ml/kg of a 20% ethanol solution in water), and the blood concentrations of alcohol and acetaldehyde were analyzed up to 7 h after the treatment. Pre-treatment with the sap significantly decreased the blood ethanol and acetaldehyde concentrations after 5 h when compared with ethanol treatment alone (a negative control). The expression levels of liver alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) mRNA were increased significantly in animals pre-treated with A. okamotoanum sap when compared with negative and positive controls. The data suggest that sap pre-treatment enhanced the alcohol metabolism rate in the rat liver. To investigate the involvement of mitochondrial regulation in the ethanol-induced hepatocyte apoptosis, we carried out an immunohistochemical analysis of Bax and Bcl-2. Pre-treatment with sap significantly decreased Bax expression and increased Bcl-2 expression 7 h after ethanol administration when compared with the negative control. The data suggest that A. okamotoanum sap pre-treatment may reduce the alcohol-induced oxidative stress in the rat liver.

    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.

    The severity of ethanol-induced liver injury is associated with oxidative stress and lipid accumulation in the liver. Core circadian clock is known to mediate antioxidative enzyme activity and lipid metabolism. However, the link between circadian clock and ethanol-induced hepatotoxicity remains unclear. Here we showed that extents of acute ethanol-induced liver injury and steatosis in mice exhibit circadian variations consistent with hepatic expression of Period (Per) genes. Mice lacking clock gene Per1 displayed less susceptible to ethanol-induced liver injury, as evidenced by lower serum transaminase activity and less severe histopathological changes. Ethanol-induced lipid peroxidation was alleviated in Per1−/− mice. However, Per1 deletion had no effect on antioxidants depletion caused by ethanol administration. Ethanol-induced triglycerides (TG) accumulation in the serum and liver was significantly decreased in Per1−/− mice compared with that in wild-type (WT) mice. Analysis of gene expression in the liver revealed peroxisome proliferators activated receptor-gamma (PPARγ) and its target genes related to TG synthesis are remarkably down-regulated in Per1−/− mice. HepG2 cells were treated with ethanol at 150 mM for 3 days. Per1 overexpression augmented lipid accumulation after treatment with ethanol in HepG2 cells, but had no effect on ethanol-induced oxidative stress. Expression of genes related to lipogenesis, including PPARγ and its target genes, was up-regulated in cells overexpressing Per1. In conclusion, these results indicated that circadian rhythms of ethanol-induced hepatotoxicity are controlled by clock gene Per1, and deletion of Per1 protected mice from ethanol-induced liver injury by decreasing hepatic lipid accumulation

    Full Text Available In patients at risk for sudden ethanol (ETOH intravascular absorption, prompt treatment of pulmonary hypertension (PHTN will minimise the risk of cardiovascular decompensation. We investigated the haemodynamic effects of intravenous ETOH and the pulmonary vasodilatory effects of a sildenafil analogue (UK343-664 and nitroglycerin (NTG during ETOH-induced PHTN in pigs. We studied pulmonary and systemic haemodynamics, and right ventricular rate or time derivate of pressure rise during ventricular contraction ( =dP/dT, as an index of contractility, in 23 pigs. ETOH was infused at a rate of 50 mg/kg/min, titrated to achieve a twofold increase in mean pulmonary arterial pressure (MPAP, and then discontinued. The animals were randomised to receive an infusion of 2 ml/kg ( n = 7 normal saline, a 500-μg/kg bolus of UK343-664 ( n = 8, or NTG 1 μg/kg ( n = 8; each was given over 60 seconds. Following ETOH infusion, dP/dT decreased central venous pressure (CVP, and MPAP increased significantly, resulting in significantly increased pulmonary vascular resistance (PVR. Within 2 minutes after treatment with either drug, CVP, heart rate (HR, and the systemic vascular resistance-to-pulmonary vascular resistance (SVR/PVR ratio returned to baseline. However, at that time, only in the UK343-664 group, MPAP and dP/dT partially recovered and were different from the respective values at PHTN stage. NTG and UK343-664 decreased PVR within 2 minutes, from 1241±579 and 1224±494 dyne · cm/sec 5 , which were threefold-to-fourfold increased baseline values, to 672±308 and 538±203 dyne · cm/sec 5 respectively. However, only in the UK343-664 group, changes from baseline PVR values after treatment were significant compared to the maximal change during target PHTN. Neither drug caused a significant change in SVR. In this model of ETOH-induced PHTN, both UK343-664 and NTG were effective pulmonary vasodilators with a high degree of selectivity. However, the changes from

    Treatment of gastric ulcers with medicinal plants is quite common in traditional medicine worldwide. Cymbopogon citratus (DC) Stapf. leaves infusion has been used in folk medicine of many tropical and subtropical regions to treat gastric disturbances. The aim of this study was to assess the potential gastroprotective activity of an essential oil-free infusion from C. citratus leaves in acute gastric lesions induced by ethanol in rat. The study was performed on adult male Wistar rats (234.0±22.7g) fasted for 24h but with free access to water. The extract was given orally before (prevention) or after (treatment) intragastric administration of absolute ethanol. Effects of dose (28 or 56mg/kg of body weight) and time of contact of the extract with gastric mucosa (1 or 2h) were also assessed. Animals were sacrificed, being the stomachs removed and the lesions were assessed by macroscopic observation and histopathology. C. citratus extract, given orally before or after ethanol, significantly (P<0.01) reduced gastric mucosal injury compared with control group (vehicle+ethanol). The effect does not appear to be dose-dependent. Results also suggested that the extract is more effective when the time of contact with gastric mucosa increases. The results of this assay confirm the gastroprotective activity of C. citratus extract on experimental gastric lesions induced by ethanol, contributing for the pharmacological validation of its traditional use.

    Drinking to alleviate the symptoms of acute withdrawal is included in diagnostic criteria for alcoholism, but the contribution of acute withdrawal relief to high alcohol intake has been difficult to model in animals. Ethanol dependence was induced by passive intragastric ethanol infusions in C57BL/6J (B6) and DBA/2J (D2) mice; nondependent control animals received water infusions. Mice were then allowed to self-administer ethanol or water intragastrically. The time course of acute withdrawal was similar to that produced by chronic ethanol vapor exposure in mice, reaching a peak at 7 to 9 hours and returning to baseline within 24 hours; withdrawal severity was greater in D2 than in B6 mice (experiment 1). Postwithdrawal delays in initial ethanol access (1, 3, or 5 days) reduced the enhancement in later ethanol intake normally seen in D2 (but not B6) mice allowed to self-infuse ethanol during acute withdrawal (experiment 2). The postwithdrawal enhancement of ethanol intake persisted over a 5-day abstinence period in D2 mice (experiment 3). D2 mice allowed to drink ethanol during acute withdrawal drank more ethanol and self-infused more ethanol than nondependent mice (experiment 4). Alcohol access during acute withdrawal increased later alcohol intake in a time-dependent manner, an effect that may be related to a genetic difference in sensitivity to acute withdrawal. This promising model of negative reinforcement encourages additional research on the mechanisms underlying acute withdrawal relief and its role in determining risk for alcoholism.

    Full Text Available Alcoholic liver disease (ALD results from alcohol overconsumption and is among the leading causes of liver-related morbidity and mortality worldwide. Elevated expression of vascular endothelial growth factor (VEGF and its receptors has been observed in ALD, but how it contributes to ALD pathophysiology is unclear. Here, we investigated the impact of VEGF signaling inhibition on an established zebrafish model of acute alcoholic liver injury. Kdrl activity was blocked by chemical inhibitor treatment or by genetic mutation. Exposing 4-day-old zebrafish larvae to 2% ethanol for 24 h induced hepatic steatosis, angiogenesis and fibrogenesis. The liver started self-repair once ethanol was removed. Although inhibiting Kdrl did not block the initial activation of hepatic stellate cells during ethanol treatment, it suppressed their proliferation, extracellular matrix protein deposition and fibrogenic gene expression after ethanol exposure, thus enhancing the liver repair. It also ameliorated hepatic steatosis and attenuated hepatic angiogenesis that accelerated after the ethanol treatment. qPCR showed that hepatic stellate cells are the first liver cell type to increase the expression of VEGF ligand and receptor genes in response to ethanol exposure. Both hepatic stellate cells and endothelial cells, but not hepatic parenchymal cells, expressed kdrl upon ethanol exposure and were likely the direct targets of Kdrl inhibition. Ethanol-induced steatosis and fibrogenesis still occurred in cloche mutants that have hepatic stellate cells but lack hepatic endothelial cells, and Kdrl inhibition suppressed both phenotypes in the mutants. These results suggest that VEGF signaling mediates interactions between activated hepatic stellate cells and hepatocytes that lead to steatosis. Our study demonstrates the involvement of VEGF signaling in regulating sustained liver injuries after acute alcohol exposure. It also provides a proof of principle of using the

    Fish sauce is a traditional condiment in Southeast Asia, normally containing high concentration of salt. The solubility of salt is lower in ethanol than in water. In the present study, fish sauce was desalted by ethanol treatment (including the processes of ethanol addition, mixing, standing and rotary evaporation). The salt concentration of fish sauce decreased significantly from 29.72 to 19.72 g/100 mL when the treated ethanol concentration was 21% (v/v). The addition of more than 12% (v/v) of ethanol significantly reduced dry weight, total soluble nitrogen content and amino acids nitrogen content. Besides, the quality of fish sauce remained first grade if no more than 21% (v/v) of ethanol was used. Furthermore, sensory analyses showed that ethanol treatment significantly reduced the taste of salty and the odor of ammonia. This study demonstrates that ethanol treatment is a potential way to decrease salt content in fish sauce, which meanwhile limits the losses of nutritional and sensorial values within an acceptable range.

    Previous studies have shown that inbred mouse strains differ in the development of tolerance to both nicotine and ethanol, indicating that genetic factors regulate tolerance development. Those mouse strains that are most sensitive to an acute challenge dose of either drug develop the most tolerance to that drug. The ethanol-sensitive long-sleep (LS) mice are more sensitive to several behavioral and physiological effects of nicotine than are the ethanol-resistant short-sleep (SS) mice. The experiments reported here assessed whether the LS and SS mice develop tolerance to ethanol after chronic treatment with ethanol-containing liquid diets and whether cross-tolerance to nicotine also developed. Tolerance and cross-tolerance were measured by assessing the effects of acute challenge doses of drug on Y-maze crossing and rearing activities, heart rate and body temperature. The LS mice developed tolerance to ethanol's effects on three of the four measures and were cross-tolerant to nicotine on all of the measures. In contrast, the SS mice developed tolerance to ethanol for only two of the measures, but failed to develop cross-tolerance to any action of nicotine. These findings support the hypothesis that ethanol and nicotine share sites of action and that common genes regulate responses to these two drugs. Evidence suggests that tolerance to nicotine may be related to an up-regulation of brain nicotinic receptors, at least in some inbred mouse strains, but chronic ethanol treatment did not reproducibly change either [3H]nicotine or alpha-[125I]bungarotoxin binding. Therefore, other mechanisms must underlie the tolerance and cross-tolerance that was seen.

    The effects of intravenous ethanol and ethanol plus furosemide on pancreatic capillary blood flow (PCBF) were investigated using a laser-Doppler flowmeter. Forty Sprague-Dawley male rats were divided into 4 groups: (1) control, (2) 80% ethanol, (3) 80% ethanol plus furosemide, and (4) furosemide. Mean arterial blood pressure and heart rate were monitored. Levels of serum amylase, calcium, electrolytes, ethanol, and furosemide (groups 3 and 4) were measured, and samples of pancreatic tissue were obtained. The ethanol and furosemide levels were statistically different (p 0.05) between groups 1 and 4. Histopathologic analysis revealed swollen acini in group 2 and sparse focal necrosis without acinar swelling in group 3. The depressant effect of ethanol on PCBF may be the result of its direct action on pancreatic cells causing edema and capillary compression rather than on primary vascular control mechanisms that adjust blood flow. Furosemide counters this effect.

    Ethanol (ET) is a substance that modulates the Central Nervous System (CNS). Frequently, ET intake occurs combined with energy drinks, which contain taurine (TA), an important amino acid found in the body (i.e brain and muscles). Although TA administration has been used in the improvement of physical performance, the impact of TA, ET and exercise remains unknown. This study aimed to analyze the acute effect of 6g of Taurine (TA), 0.6 mL∙kg-1 of Ethanol (ET), and Taurine combined with Ethanol (TA+ET) ingestion on the electrocortical activity before and after a moderate intensity exercise in 9 subjects, 5 women (counterbalanced experimental design). In each of the 4 treatments (Placebo—PL, TA, ET and TA+ET), electroencephalography (EEG) tests were conducted in order to analyze changes in absolute beta power (ABP) in the frontal lobe in 3 moments: baseline (before ingestion), peak (before exercise) and post-exercise. In the PL treatment, the frontal areas showed decrease in ABP after exercise. However, in the ET+TA treatment, ABP values were greater after exercise, except for Fp1. The ET treatment had no effect on the Superior Frontal Gyrus area (F3, Fz and F4) and ABP decreased after exercise in Fp1 and Fp2. In the TA treatment, ABP increased after exercise, while it decreased at the peak moment in most of the frontal regions, except for Fp1, F3 and Fz. We concluded that after a moderate intensity exercise, a decrease in cortical activity occurs in placebo treatment. Moreover, we found a inhibitory effect of TA on cortical activity before exercise and a increased in cortical activity after exercise. A small ET dose is not enough to alter ABP in all regions of the frontal cortex and, in combination with TA, it showed an increase in the frontal cortex activity at the post-exercise moment.

    This study investigated the protective effect of Allium neapolitanum Cyr., a spontaneous species of the Italian flora, compared with garlic (Allium sativum L.) on liver injury induced by ethanol in rats. Male albino Wistar rats were orally treated with fresh Allium homogenates (leaves or bulbs, 250 mg/kg) daily for 5 days, whereas controls received vehicle only. At the end of the experimental 5-day period, the animals received an acute ethanol dose (6 mL/kg, i.p.) 2 hours before the last Allium administration and were sacrificed 6 hours after ethanol administration. The activities of catalase (CAT), superoxide dismutase (SOD), and glutathione reductase (GR) and the levels of malondialdehyde (MDA), ascorbic acid (AA), and reduced (GSH) and oxidized glutathione in liver tissue were determined. Administration of both Allium species for 5 days (leaves or bulbs) led to no statistical variation of nonenzymatic parameters versus the control group; otherwise Allium treatment caused an increase of GSH and AA levels compared with the ethanol group and a diminution of MDA levels, showing in addition that A. neapolitanum bulb had the best protective effect. Regarding to enzymatic parameters, GR and CAT activities were enhanced significantly compared with the ethanol group, whereas SOD activity showed a trend different from other parameters estimated. However, the treatment with both Allium species followed by acute ethanol administration reestablished the nonenzymatic parameters similar to control values and enhanced the activities of the enzymes measured. These results suggest that fresh Allium homogenates (leaves or bulbs) possess antioxidant properties and provide protection against ethanol-induced liver injury.

    Full Text Available Chronic and acute alcohol exposure has been extensively reported to cause oxidative stress in hepatic and extra-hepatic tissues. Watermelon (Citrullus lanatus is known to possess various beneficial properties including; antioxidant, anti-inflammatory, analgesic, anti-diabetic, anti-ulcerogenic effects. However, there is a lack of pertinent information on its importance in acute alcohol-induced hepato- and neuro-toxicity. The present study evaluated the potential protective effects of watermelon juice on ethanol-induced oxidative stress in the liver and brain of male Wistar rats. Rats were pre-treated with the watermelon juice at a dose of 4 ml/kg body weight for a period of fifteen days prior to a single dose of ethanol (50%; 12 ml/kg body weight. Ethanol treatment reduced body weight gain and significantly altered antioxidant status in the liver and brain. This is evidenced by the significant elevation of malondialdehyde (MDA concentration; depletion in reduced glutathione (GSH levels and an increased catalase (CAT activity in the brain and liver. There was no significant difference in the activity of glutathione peroxidase (GPX in the liver and brain.Oral administration of watermelon juice for fifteen (15 days prior to ethanol intoxication, significantly reduced the concentration of MDA in the liver and brain of rats. In addition, water melon pre-treatment increased the concentration of GSH and normalized catalase activity in both tissues in comparison to the ethanol control group. Phytochemical analysis revealed the presence of phenol, alkaloids, saponins, tannins and steroids in watermelon juice. Our findings indicate that watermelon juice demonstrate anti-oxidative effects in ethanol-induced oxidation in the liver and brain of rats; which could be associated with the plethora of antioxidant phyto-constituents present there-in.

    Binge drinking represses host innate immunity and leads to a high risk of infection. Acute EtOH-pretreated macrophages exhibit a decreased production of proinflammatory mediators in response to LPS. ATF3 is induced and counter-regulates the LPS/TLR4 inflammatory cascade. Here, we investigated the potential role of ATF3 in LPS tolerance in acute ethanol-pretreated macrophages. We found that there was an inverse correlation between ATF3 and LPS-induced TNF-α production in acute ethanol-pretreated murine monocytes and macrophages. The knockdown of ATF3 attenuated the inhibitory effects of acute ethanol treatment on LPS-induced TNF-α production. Furthermore, ChIP assays and co-IP demonstrated that ATF3, together with HDAC1, negatively modulated the transcription of TNF-α. In binge-drinking mice challenged with LPS, an up-regulation of ATF3 and HDAC1 and a concomitant decrease in TNF-α were observed. Given that HDAC1 was concomitantly induced in acute ethanol-exposed monocytes and macrophages, we used the HDACi TSA or silenced HDAC1 to explore the role of HDAC1 in acute ethanol-treated macrophages. Our results revealed that TSA treatment and HDAC1 knockdown prevented acute ethanol-induced ATF3 expression and the inhibition of TNF-α transcription. These data indicated a dual role for HDAC1 in acute ethanol-induced LPS tolerance. Furthermore, we showed that the induction of ATF3 led to the impaired migration of BM monocytes and macrophages. Overall, we present a novel role for ATF3 in the inhibition of LPS-induced TNF-α and in the impairment of monocyte and macrophage migration. © Society for Leukocyte Biology.

    In the last time the alcohol consumption among children and adolescents is a big theme in all kind of media. The ethanol consumption among children and adolescents has risen during the last years, but also new hazardous drinking patterns like "binge-drinking" are increasing. These drinking episodes are responsible for many hospital presentations of children and adolescents with acute ethanol intoxication. This study is a retrospective analysis of 173 patients admitted to the university children hospital of Leipzig due to acute ethanol intoxication during the period 1998-2004. Investigated parameters were: socio-demographic factors, clinical presentation and management as well as quantity and type of alcohol. During the years 1998-2004 the rate of alcohol intoxicated patients in this study increased, from 1998-2003 at about 171.4%. Totally 173 patients with an average age of 14.5 years were admitted to the university children hospital. There were significantly more boys than girls. The mean blood alcohol concentration of these patients was 1.77%. Some of the patients had severe symptoms. 62 were unconscious, 2 were in coma and at least 3 patients had to be ventilated. A difference between socioeconomic groups could be observed by comparing the different school types. 44.8% of the patients went to the middle school. Furthermore 17 patients of this study had mental disorders or psychosocial problems and were therefore in psychological or psychiatric treatment. In this study a significant influence of social classes or psychosocial problems on alcohol consumption such as binge-drinking leading to acute ethanol intoxication could not be found. Alarming is the increasing number of ethanol intoxicated patients, the young age, the high measured blood ethanol concentrations and the severe symptoms of these patients. This is the reason why early and intensive prevention strategies are required.

    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.

    BACKGROUND: Autonomous thyroid nodules can be treated by a variety of methods. We assessed the efficacy of percutaneous ethanol injection in treating autonomous thyroid nodules. METHODS: 35 patients diagnosed by technetium-99 scanning with hyperfunctioning nodules and suppressed sensitive TSH (sTSH) were given sterile ethanol injections under ultrasound guidance. 29 patients had clinical and biochemical hyperthyroidism. The other 6 had sub-clinical hyperthyroidism with suppressed sTSH levels (thyroid hormone levels. Ethanol injections were performed once every 1-4 weeks. Ethanol injections were stopped when serum T3, T4 and sTSH levels had returned to normal, or else injections could no longer be performed because significant side effects. Patients were followed up at 3, 6 and, in 15 patients, 24 months after the last injection. RESULTS: Average pre-treatment nodule volume [18.2 PlusMinus; 12.7 ml] decreased to 5.7 PlusMinus; 4.6 ml at 6 months follow-up [P thyroid hormone levels at 3 and 6 months follow-up [P 0.05]. Ethanol injections were well tolerated by the patients, with only 2 cases of transient dysphonia. CONCLUSION: Our findings indicate that ethanol injection is an alternative to surgery or radioactive iodine in the treatment of autonomous thyroid nodules.

    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.

  13. Lipid environment modulates the development of acute tolerance to ethanol in Caenorhabditis elegans.

    Directory of Open Access Journals (Sweden)

    Jill C Bettinger

    Full Text Available The development of tolerance to a drug at the level of the neuron reflects a homeostatic mechanism by which neurons respond to perturbations of their function by external stimuli. Acute functional tolerance (AFT to ethanol is a fast compensatory response that develops within a single drug session and normalizes neuronal function despite the continued presence of the drug. We performed a genetic screen to identify genes required for the development of acute functional tolerance to ethanol in the nematode C. elegans. We identified mutations affecting multiple genes in a genetic pathway known to regulate levels of triacylglycerols (TAGs via the lipase LIPS-7, indicating that there is an important role for TAGs in the development of tolerance. Genetic manipulation of lips-7 expression, up or down, produced opposing effects on ethanol sensitivity and on the rate of development of AFT. Further, decreasing cholesterol levels through environmental manipulation mirrored the effects of decreased TAG levels. Finally, we found that genetic alterations in the levels of the TAG lipase LIPS-7 can modify the phenotype of gain-of-function mutations in the ethanol-inducible ion channel SLO-1, the voltage- and calcium-sensitive BK channel. This study demonstrates that the lipid milieu modulates neuronal responses to ethanol that include initial sensitivity and the development of acute tolerance. These results lend new insight into studies of alcohol dependence, and suggest a model in which TAG levels are important for the development of AFT through alterations of the action of ethanol on membrane proteins.

    The activity of the major drug-metabolizing enzymes, the mono-oxygenases, can be inhibited by an acute dose of ethanol. We set out to determine whether age has any relation to the degree of inhibition produced by ethanol, using acetanilide as a model substrate. Eight healthy young subjects (mean age 26 years) and eight healthy elderly subjects (mean age 72 years) were studied on two occasions, once receiving acetanilide alone and once acetanilide with 75 ml vodka (30 g ethanol). The clearance of acetanilide was significantly lower (p less than 0.05) in the elderly subjects at 27 +/- 3 l/h compared to 38 +/- 2 l/h in young subjects. No age-related differences in peak blood ethanol concentrations or ethanol elimination rates were noted. After ethanol, acetanilide clearance fell 18% to 31 +/- 3 l/h in young subjects (p = 0.05) and by 15% to 23 +/- 2 l/h in elderly subjects (p = 0.08). This suggests that the elderly do not suffer greater impairment of drug oxidation after acute ethanol ingestion than do the young.

    Full Text Available Acute pancreatitis is an acute inflammatory process of the pancreas with variable involvement of other regional tissues or other organ systems. The severe form of the disease occurs in 10-20% of cases, and usually requires prolonged hospitalization due to a frequent local and systemic complications. Additionally, considerable mortality despite diagnostic and therapeutic advances, makes this disease a serious health problem nowadays. The aim of this study was to conduct a review of randomized controlled trials to determine differences in the efficiency between standard methods of treatment for severe acute pancreatitis and new treatment ways in terms of decreased mortality. Search of the 'Medline' database of original scientific papers and systematic review articles was made, using a combination of the following keywords: acute pancreatitis, treatment, mortality. In total 914 papers were found, published in the last 13 years; 14 of 64 randomized controlled clinical trials met the selection criteria and were eligible for inclusion. From a total of 16 papers, the conservative treatment was related to 11, which includes some of the new treatment methods, while the effects of new methods of treatment have been the subject of research in the four studies. Combined endoscopic and surgical treatment was applied in only one study. The largest sample of 290 patients was included in the study with platelet activation factor antagonist, while the smallest sample of 22 patients was used in the study that compared total parenteral with enteral nutrition. Continuous regional arterial infusion of protease inhibitors in combination with antibiotics, intravenous supplementation of alanyl-glutamine dipeptide and the early, high-volume continuous veno-venous hemofiltration showed the best results in the treatment of patients with severe acute pancreatitis. Also, the use of low molecular weight heparin and enteral nutrition significantly reduced mortality.

    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. Thieme Medical Publishers.

    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 LD 50 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)

    Ethanol production from sugarcane in Brazil is a well-established industry, with relatively simple operations and high yield. The ethanol primarily serves as a renewable fuel blending with gasoline and diesel to increase the energy security in Brazil. Several environmental concerns are emerged around the by-products from this industry. Vinasse, the liquid fraction generated from the rectification and distillation operations of ethanol, is a sulfur-rich, low pH, dark-colored, and odorous effluent, produced at volumes as high as 20-fold of ethanol. Traditional wastewater treatments, such as bioprocessing, advanced oxidative processes, anaerobic digestion (AD), and chemical-based processes, have been applied to vinasse management. Despite most of its utilization being in fertirrigation practices, vinasse may represent a key factor in enhancing profitability and environmental outcomes of a sugarcane-to-ethanol plant. The application of some upgrade solutions to sugarcane-derived vinasse may represent additional sources of energy, production of animal feed components, and reduction in water consumption within a plant. The use of mature technologies, yet not widespread in the sugarcane-to-ethanol industry, could help attenuate environmental concerns. Oxidation and chemical processes, AD, and microbial fermentation have been presented as alternative impactful alternatives to (i) reduce its organic and mineral load, converting it to a feedstock with fewer environmental applications when applied as fertilizer and (ii) to convert organic matter and nutrients to a nutritious biomass, simultaneously increasing water reclamation potential by plants. This mini-review article provides a critical and comprehensive summary of the alternatives developed or under development to vinasse management.

  4. Acute effects of ethanol in the control of protein synthesis in isolated rat liver cells

    Girbes, T.; Susin, A.; Ayuso, M.S.; Parrilla, R.

    1983-01-01

    The acute effect of ethanol on hepatic protein synthesis is a rather controversial issue. In view of the conflicting reports on this subject, the effect of ethanol on protein labeling from L-[ 3 H]valine in isolated liver cells was studied under a variety of experimental conditions. When tracer doses of the isotope were utilized, ethanol consistently decreased the rate of protein labeling, regardless of the metabolic conditions of the cells. This inhibition was not prevented by doses of 4-methylpyrazole large enough to abolish all the characteristic metabolic effects of ethanol, and it was not related to perturbations on the rates of L-valine transport and/or proteolysis. When ethanol was tested in the presence of saturating doses of L-[ 3 H]valine no effect on protein labeling was observed. These observations suggest that the ethanol effect in decreasing protein labeling from tracer doses of the radioactive precursor does not reflect variations in the rate of protein synthesis but reflects changes in the specific activity of the precursor. These changes probably are secondary to variations in the dimensions of the amino acid pool utilized for protein synthesis. Even though it showed a lack of effect when tested alone, in the presence of saturating doses of the radioactive precursor ethanol inhibited the stimulatory effects on protein synthesis mediated by glucose and several gluconeogenic substrates. This effect of ethanol was not prevented by inhibitors of alcohol dehydrogenase, indicating that a shift of the NAD system to a more reduced state is not the mediator of its action. It is suggested that ethanol probably acted by changing the steady-state levels of some common effector(s) generated from the metabolism of all these fuels or else by preventing the inactivation of a translational repressor

    Oxidative stress and inflammation are well-documented pathological factors in alcoholic liver disease (ALD). Artichoke ( Cynara scolymus L.) is a healthy food and folk medicine with anti-oxidative and anti-inflammatory properties. This study aimed to evaluate the preventive effects of ethanolic extract from artichoke against acute alcohol-induced liver injury in mice. Male Institute of Cancer Research mice were treated with an ethanolic extract of artichoke (0.4, 0.8, and 1.6 g/kg body weight) by gavage once daily. Up to 40% alcohol (12 mL/kg body weight) was administered orally 1 h after artichoke treatment. All mice were fed for 10 consecutive days. Results showed that artichoke extract significantly prevented elevated levels of aspartate aminotransferase, alanine aminotransferase, triglyceride, total cholesterol, and malondialdehyde. Meanwhile, the decreased levels of superoxide dismutase and glutathione were elevated by artichoke administration. Histopathological examination showed that artichoke attenuated degeneration, inflammatory infiltration and necrosis of hepatocytes. Immunohistochemical analysis revealed that expression levels of toll-like receptor (TLR) 4 and nuclear factor-kappa B (NF-κB) in liver tissues were significantly suppressed by artichoke treatment. Results obtained demonstrated that artichoke extract exhibited significant preventive protective effect against acute alcohol-induced liver injury. This finding is mainly attributed to its ability to attenuate oxidative stress and suppress the TLR4/NF-κB inflammatory pathway. To the best of our knowledge, the underlying mechanisms of artichoke on acute ALD have been rarely reported.

    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.

    In assessing acute asthma, the physician must seek specific historical features, symptoms and physical findings. Recent work has shown, however, that while these features are associated with severity, their absence does not imply benignity. Objective measures of pulmonary function are required for accurate assessment of severity. A sequential treatment regimen using nebulized bronchodilators, vigorous rehydration, aminophylline, and corticosteroids should be employed. Status asthmaticus may r...

    The purpose of this study was to evaluate the efficacy and safety of US-guided percutaneous ethanol injection for the treatent of benign cold thyroid nodules. Twenty-five patients with benign cold thyroid nodules (volume of each at least 2ml proven by PCNA to be adenomatous hyperplasia, and cold nodule by thyroid scan) underwent a total of one to three percutaneous ethanol injections (PEI) at intervals of one or two months. The mean amount of ethanol used was 6.2(range, 1.5-8)ml, depending on the volume of the nodule. Follow up ultrasonography was performed one to four months after the final session. The initial volume of nodules was 11.4±4.1(range, 2.5-41.4)ml, and in all cases this fell by 56.1±22.3%(range, 10.9-92.1%);in all cases, follow-up ultrasonography showed that echogeneity was lower and its pattern was heterogeneous. There were no important longstanding complications;the most common side effect was acute pain at the injection site(n=3D9), and in one case, transient vocal cord palsy occurred. Our results show that US-guided percutaneous injection of ethanol is an effective and a safe procedure for the treatment of benign cold thyroid nodules, and is thus an alternative to surgery or hormone therapy.=20

    The development of ethanol dependence is associated with alterations in hypothalamic-pituitary-adrenal (HPA) axis and activation of type II glucocorticoid receptors (GR). These effects may contribute to withdrawal-associated anxiety, craving and relapse to drinking. The present studies examined acute and oral administration of the novel, selective and competitive GR antagonist ORG 34517 on the severity of ethanol withdrawal. Adult, male Sprague-Dawley rats were administered ethanol (4g/kg/i.g.) twice daily for 5 days followed by 2 days of withdrawal for 1, 2 or 3 consecutive cycles. Blood ethanol levels (BELs) were determined at 0930 on Day 4 of each week, while blood corticosterone levels (BCLs) were obtained at 11:00hours on the first day of each ethanol withdrawal. During early withdrawal, subjects received oral administration of ORG 345617 (60mg/kg/i.g.) or a placebo and withdrawal was monitored. Peak BELs of 225.52mg/dl were observed during the third week. Withdrawal from three cycles of the regimen produced marked behavioral abnormalities (e.g., aggression, rigidity, and hypoactivity) and significant increases in BCLs of ethanol-dependent subjects. Acute, oral administration of ORG 34517 during early withdrawal significantly reduced both the severity of ethanol withdrawal, as reflected in reduced rigidity, aggression, and hypoactivity, and elevations in BCL without producing any sedative-like effects. The present findings demonstrate that repeated ethanol exposure and withdrawal is associated with significant behavioral abnormalities and dysregulation of HPA axis activation. Further these data suggest that selective GR antagonists should be further considered as putative pharmacotherapies for treatment of ethanol dependence. Copyright © 2015 Elsevier Ireland Ltd.

    Compounds with anti-glutamatergic properties currently in clinical use for various indications (e.g., Alzheimer's disease, epilepsy, psychosis, mood disorders) have potential utility as novel treatments for alcoholism. Enhanced sensitivity to certain acute intoxicating effects (ataxia, sedative) of alcohol may be one mechanism by which anti-glutamatergic drugs modulate alcohol use. We examined the effects of six compounds (memantine, dextromethorphan, haloperidol, lamotrigine, oxcarbazepine, topiramate) on sensitivity to acute intoxicating effects of ethanol (ataxia, hypothermia, sedation/hypnosis) in C57BL/6J mice. Analysis of topiramate was extended to determine the influence of genetic background (via comparison of the 129S1, BALB/cJ, C57BL/6J, DBA/2J inbred strains) and prior stress history (via chronic exposure of C57BL/6J to swim stress) on topiramate's effects on ethanol-induced sedation/hypnosis. Results showed that one N-methyl-D-aspartate receptor (NMDAR) antagonist, memantine, but not another, dextromethorphan, potentiated the ataxic but not hypothermic or sedative/hypnotic effects of ethanol. Haloperidol increased ethanol-induced ataxia and sedation/hypnosis to a similar extent as the prototypical NMDAR antagonist MK-801. Of the anticonvulsants tested, lamotrigine accentuated ethanol-induced sedation/hypnosis, while oxcarbazepine was without effect. Topiramate was without effect per se under baseline conditions in C57BL/6J, but had a synergistic effect with MK-801 on ethanol-induced sedation/hypnosis. Comparing inbred strains, topiramate was found to significantly potentiated ethanol's sedative/hypnotic effects in BALB/cJ, but not 129S1, C57BL/6J or DBA/2J strains. Topiramate also increased ethanol-induced sedation/hypnosis in C57BL/6J after exposure to chronic stress exposure. Current data demonstrate that, with the exception of MK-801 and haloperidol, the compounds tested had either no significant or assay-selective effects on sensitivity to acute

    Fermentation is one of the most critical steps of the fuel ethanol production and it is directly influenced by the fermentation system, selected yeast, and bacterial contamination, especially from the genus Lactobacillus. To control the contamination, the industry applies antibiotics and biocides; however, these substances can result in an increased cost and environmental problems. The use of the acid treatment of cells (water-diluted sulphuric acid, adjusted to pH 2·0-2·5) between the fermentation cycles is not always effective to combat the bacterial contamination. In this context, this study aimed to evaluate the effect of ethanol addition to the acid treatment to control the bacterial growth in a fed-batch system with cell recycling, using the industrial yeast strain Saccharomyces cerevisiae PE-2. When only the acid treatment was used, the population of Lactobacillus fermentum had a 3-log reduction at the end of the sixth fermentation cycle; however, when 5% of ethanol was added to the acid solution, the viability of the bacterium was completely lost even after the first round of cell treatment. The acid treatment +5% ethanol was able to kill L. fermentum cells without affecting the ethanol yield and with a low residual sugar concentration in the fermented must. In Brazilian ethanol-producing industry, water-diluted sulphuric acid is used to treat the cell mass at low pH (2·0) between the fermentative cycles. This procedure reduces the number of Lactobacillus fermentum from 10 7 to 10 4  CFU per ml. However, the addition of 5% ethanol to the acid treatment causes the complete loss of bacterial cell viability in fed-batch fermentation with six cell recycles. The ethanol yield and yeast cell viability are not affected. These data indicate the feasibility of adding ethanol to the acid solution replacing the antibiotic use, offering a low cost and a low amount of residue in the biomass. © 2017 The Society for Applied Microbiology.

    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

    Neonatal alcohol exposure in rodents causes dramatic neurodegenerative effects throughout the developing nervous system, particularly in the striatum, acutely after exposure. These acute neurodegenerative effects are augmented in mice lacking adenylyl cyclases 1 and 8 (AC1/8) as neonatal mice with a genetic deletion of both AC isoforms (DKO) have increased vulnerability to ethanol-induced striatal neurotoxicity compared to wild type (WT) controls. While neonatal ethanol exposure is known to negatively impact cognitive behaviors, such as executive functioning and working memory in adolescent and adult animals, the threshold of ethanol exposure required to impinge upon developmental behaviors in mice has not been extensively examined. Therefore, the purpose of this study was to determine the behavioral effects of neonatal ethanol exposure using various striatal-dependent developmental benchmarks and to assess the impact of AC1/8 deletion on this developmental progression. WT and DKO mice were treated with 2.5 g/kg ethanol or saline on postnatal day (P)6 and later subjected to the wire suspension, negative geotaxis, postural reflex, grid hang, tail suspension and accelerating rotarod tests at various time points. At P30, mice were evaluated for their hypnotic responses to 4.0 g/kg ethanol by using the loss of righting reflex assay and ethanol-induced stimulation of locomotor activity after 2.0 g/kg ethanol. Ethanol exposure significantly impaired DKO performance in the negative geotaxis test while genetic deletion of AC1/8 alone increased grid hang time and decreased immobility time in the tail suspension test with a concomitant increase in hindlimb clasping behavior. Locomotor stimulation was significantly increased in animals that received ethanol as neonates, peaking significantly in ethanol-treated DKO mice compared to ethanol-treated WT controls, while sedation duration following high-dose ethanol challenge was unaffected. These data indicate that the

    Rats were exposed to toluene at a wide range of concentrations from 50 to 4000 ppm for six hours, and the effects of ethanol and phenobarbital (PB) treatments on the pharmacokinetics of toluene metabolism were investigated. Ethanol treatment influenced toluene metabolism mainly at low exposure concentrations. Thus ethanol accelerated the clearance of toluene from blood only when the blood concentration of toluene was not high (less than 360 microM), and ethanol increased hippuric acid (HA) ex...

    The roots of Berchemia lineate (L.) DC. (Rhamnaceae) have been long used as a remedy for the treatment of some diseases in Guangxi Province, China. The present study investigates the hepatoprotective effect of Berchemia lineate ethanol extract (BELE) on CCl4-induced acute liver damage in mice. Effect of BELE administrated for 7 consecutive days was evaluated in mice by the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), albulin (ALB), globulin (GLB), and total protein (TP) levels, as well as liver superoxide dismutase (SOD) activity and malondialdehyde (MDA) level. Moreover, histopathological examinations were also taken. Compared with the model group, administration of 400 mg/kg BELE for 7 d in mice significantly decreased the serum ALT (56.25 U/L), AST (297.67 U/L), ALP (188.20 U/L), and TBIL (17.90 mol/L), along with the elevation of TP (64.67 g/L). In addition, BELE (100, 200, and 400 mg/kg, i.g.) treated mice recorded a dose-dependent increment of SOD (291.17, 310.32, and 325.67 U/mg prot) and reduction of MDA (7.27, 6.77, and 5.33 nmol/mg prot) levels. Histopathological examinations also confirmed that BELE can ameliorate CCl4-induced liver injuries, characterized by extensive hepatocellular degeneration/necrosis, inflammatory cell infiltration, congestion, and sinusoidal dilatation. The results indicated that BELE possessed remarkable protective effect against acute hepatotoxicity and oxidative injuries induced by CCl4, and that the hepatoprotective effects of BELE may be due to both the inhibition of lipid peroxidation and the increase of antioxidant activity.

    Ethanolic and hexanic extracts from fruits and leaves of Schinus molle showed ability to control several insect pests. Potential vertebrate toxicity associated with insecticidal plants requires investigation before institutional promotion. The aim of the present study was to evaluate the acute and subacute toxicity of ethanolic extracts from fruits of Schinus molle in rats. The plant extract was added to the diet at 2g/kg body weight/day during 1 day to evaluate acute toxicity and at 1g/kg body weight/day during 14 days to evaluate subacute toxicity. At the end of the exposure and after 7 days, behavioral and functional parameters in a functional observational battery and motor activity in an open field were assessed. Finally, histopathological examinations were conducted on several organs. In both exposures, an increase in the arousal level was observed in experimental groups. Also, the landing foot splay parameter increased in the experimental group after acute exposure. Only the subacute exposure produced a significant increase in the motor activity in the open field. All these changes disappeared after 7 days. None of the exposures affected the different organs evaluated. Our results suggest that ethanolic extracts from fruits and leaves of Schinus molle should be relatively safe to use as insecticide.

    Abusive alcohol consumption produces neuronal damage and biochemical alterations in the mammal brain followed by cognitive disturbances. In this work rats receiving chronic and acute alcohol intake were evaluated in a spontaneous delayed non-matching to sample/position test. Chronic alcohol-treated rats had free access to an aqueous ethanol solution as the only available liquid source from the postnatal day 21 to the end of experiment (postnatal day 90). Acute alcoholic animals received an injection of 2 g/kg ethanol solution once per week. Subjects were evaluated in two tests (object recognition and spatial recognition) based on the spontaneous delayed non-matching to sample or to position paradigm using delays of 1 min, 15 min and 60 min. Results showed that chronic and acute alcohol intake impairs the rats' performance in both tests. Moreover, chronic alcohol-treated rats were more altered than acute treated animals in both tasks. Our results support the idea that chronic and acute alcohol administration during postnatal development caused widespread brain damage resulting in behavioral disturbances and learning disabilities.

  18. Basics of acute stroke treatment

    International Nuclear Information System (INIS)

    Haass, A.

    2005-01-01

    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 O 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.

    Full Text Available 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.

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.

    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.

    Ethanol is commonly overused psychoactive substance in Poland and all around the world. It causes addiction, which occurs as a result of its chronic administration. One of the main symptoms of addiction is hunger due to psychoactive substance that prevents interruption of its adoption and contributes to relapse drinking. Acute poisoning with ethyl alcohol and alcohol withdrawal syndrome are diseases causing a potential danger to life. The prevalence of use and abuse of alcoholic beverages is a potential risk, causing health problems, including permanent damage of the central and peripheral nervous system and socio-economic problems. The aim of this study is to analyze certain aspects of the socio-economic situation of the patients hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome in 2010. 299 patients history was evaluated, among which 161 were treated for acute intoxication with ethanol and 138 due to alcohol withdrawal syndrome. Objects of interest were elements of subjective tests including: marital status of patients, their education and professional activity and the problem of homelessness. The study group consisted of 299 patients in age from 16 to 77 years, hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome. It was found that the largest group consisted of patients remaining married (42.81%) and unmarried (30.43%). Alcohol abuse affects people of all levels of education. In the present study, most patients had a vocational education (37.79%) and medium (23.08%). Patients were analyzed in terms of economic activity, among which about 40% were unemployed. In the whole group more than 10% of those were homeless. Ethyl alcohol intoxication and alcohol withdrawal represents a significant hazard. As a result of reliance, patients lose control of alcohol consumption and they

    Acute radiation dermatitis is a common side-effect of radiotherapy which often necessitates interruption of the therapy. Currently, there is no general consensus about its prevention or about the treatment of choice. The goal of this work was to focus on optimal methods to prevent and manage acute skin reactions related to radiation therapy and to determine if there are specific topical or oral agents for the prevention of this acute skin reaction. The prevention and the early treatment are the two focus points of the management of the acute radiation dermatitis. (authors)

Therefore, the present study was designed to investigate whether adolescent [postnata...

  5. 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 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

    Ethanol (ETOH) is added to unleaded gasoline to decrease environmental levels of carbon monoxide from automobiles emissions. Therefore, addition of ETOH in reformulated fuel will most likely increase and the involuntarily human exposure to this chemical will also increase. This preliminary study was undertaken to evaluate the possible neuromotor effects resulting from acute ETOH exposure by inhalation in humans. Five healthy non-smoking adult males, with no history of alcohol abuse, were exposed by inhalation, in a dynamic, controlled-environment exposure chamber, to various concentrations of ETOH (0, 250, 500 and 1,000 ppm in air) for six hours. Reaction time, body sway, hand tremor and rapid alternating movements were measured before and after each exposure session by using the CATSYS 7.0 system and a diadochokinesimeter. The concentrations of ETOH in blood and in alveolar air were also measured. ETOH was not detected in blood nor in alveolar air when volunteers were exposed to 250 and 500 ppm, but at the end of exposure to 1,000 ppm, blood and alveolar air concentrations were 0.443 mg/100ml and 253.1 ppm, respectively. The neuromotor tests did not show conclusively significant differences between the exposed and non-exposed conditions. In conclusion, this study suggests that acute exposure to ethanol at 1,000 ppm or lower or to concentrations that could be encountered upon refueling is not likely to cause any significant neuromotor alterations in healthy males.

    The mechanism underlying the vascular dysfunction induced by ethanol is not totally understood. Identification of biochemical/molecular mechanisms that could explain such effects is warranted. To investigate whether acute ethanol intake activates the vascular RhoA/Rho kinase pathway in resistance arteries and the role of NAD(P)H oxidase-derived reactive oxygen species (ROS) on such response. We also evaluated the requirement of p47phox translocation for ethanol-induced NAD(P)H oxidase activation. Male Wistar rats were orally treated with ethanol (1g/kg, p.o. gavage) or water (control). Some rats were treated with vitamin C (250 mg/kg, p.o. gavage, 5 days) before administration of water or ethanol. The mesenteric arterial bed (MAB) was collected 30 min after ethanol administration. Vitamin C prevented ethanol-induced increase in superoxide anion (O2-) generation and lipoperoxidation in the MAB. Catalase and superoxide dismutase activities and the reduced glutathione, nitrate and hydrogen peroxide (H2O2) levels were not affected by ethanol. Vitamin C and 4-methylpyrazole prevented the increase on O2- generation induced by ethanol in cultured MAB vascular smooth muscle cells. Ethanol had no effect on phosphorylation levels of protein kinase B (Akt) and eNOS (Ser1177 or Thr495 residues) or MAB vascular reactivity. Vitamin C prevented ethanol-induced increase in the membrane: cytosol fraction ratio of p47phox and RhoA expression in the rat MAB. Acute ethanol intake induces activation of the RhoA/Rho kinase pathway by a mechanism that involves ROS generation. In resistance arteries, ethanol activates NAD(P)H oxidase by inducing p47phox translocation by a redox-sensitive mechanism. O mecanismo da disfunção vascular induzido pelo consumo de etanol não é totalmente compreendido. Justifica-se, assim a identificação de mecanismos bioquímicos e moleculares que poderiam explicar tais efeitos. Investigar se a ingestão aguda de etanol ativa a via vascular RhoA/Rho quinase

  10. Increases in anxiety-like behavior induced by acute stress are reversed by ethanol in adolescent but not adult rats.

    Repeated exposure to stressors has been found to increase anxiety-like behavior in laboratory rodents, with the social anxiety induced by repeated restraint being extremely sensitive to anxiolytic effects of ethanol in both adolescent and adult rats. No studies, however, have compared social anxiogenic effects of acute stress or the capacity of ethanol to reverse this anxiety in adolescent and adult animals. Therefore, the present study was designed to investigate whether adolescent [postnatal day (P35)] Sprague-Dawley rats differ from their adult counterparts (P70) in the impact of acute restraint stress on social anxiety and in their sensitivity to the social anxiolytic effects of ethanol. Animals were restrained for 90 min, followed by examination of stress- and ethanol-induced (0, 0.25, 0.5, 0.75, and 1 g/kg) alterations in social behavior using a modified social interaction test in a familiar environment. Acute restraint stress increased anxiety, as indexed by reduced levels of social investigation at both ages, and decreased social preference among adolescents. These increases in anxiety were dramatically reversed among adolescents by acute ethanol. No anxiolytic-like effects of ethanol emerged following restraint stress in adults. The social suppression seen in response to higher doses of ethanol was reversed by restraint stress in animals of both ages. To the extent that these data are applicable to humans, the results of the present study provide some experimental evidence that stressful life events may increase the attractiveness of alcohol as an anxiolytic agent for adolescents.

    2014-12-02

    Conyza blinii H.Lév., is a type of natural plant. Its dried overground section is used to treat infections and inflammations in traditional Chinese medicine. Triterpenoidal saponins have a wide range of bioactivities, for instance, anti-cancer, anti-virus and anti-anaphylaxis. Conyza blinii saponin (CBS), mainly composed of triterpenoidal saponins, is the total saponin of Conyza blinii H.Lév. It has been reported that CBS also has gastric mucous membrane protection activity. This study aims to test CBS׳s protective activity of gastric׳s mucous membrane against ethanol. This investigation may lead to the development of novel drug from natural products as anti-ulcer agent, or as gastric mucous protective against chemical damage. CBS (Conyza blinii saponin) is the total saponin of Conyza blinii H.Lév., which was obtained as described previously. We tested the protective activity of CBS against ethanol-induced ulcer. Thirty six rats were grouped randomly as 'NORMAL', 'CONTROL', 'MODEL', 'LOW DOSE', 'MEDIUM DOSE' and 'HIGH DOSE'. The 'NORMAL' group were rats with no pathological model established within it. The 'CONTROL' group was administrated with colloidal bismuth subcitrate, while 'MODEL' group was not given any active agents apart from absolute ethanol in order to obtain gastric ulcer model. The three 'DOSE' groups were treated with different concentrations of CBS (5, 10, 20mg/mL) before administration followed by absolute ethanol. All rats were sacrificed after the experiment to acquire the gastric tissue. The ulcer index (UI), malondialdehyde (MDA) and superoxide dismutase (SOD) were measured to monitor the activity of CBS. Besides, the rat gastric tissue was made to paraffin section and stained using the Hematoxylin-Eosin (HE) method. The histopathology examination was carried out to examine CBS efficacy in terms of gastric mucous protection. We found that CBS had a profound protection activity against acute gastric ulcer induced by ethanol and this

    A case of favourable outcome of the treatment of extremely severe acute poisoning after prolonged exposure to lethal doses of methanol is reported. The complex treatment included urgent and effective elimination of the poison (multiple gastric lavage, hemodialysis), antidote therapy (administration of ethanol), correction of decompensated metabolic acidosis (alkali therapy and infusion therapy with reamberin). These measures had beneficial effect on the clinical course of poisoning and ensured its favourable outcome.

    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.

    Female DBA/2Ibg mice were treated chronically (21 days) with ethanol- or dextrin-containing liquid diets or infused chronically with nicotine (8 mg/kg/h) or saline for 10 days. The responses of these animals to challenge doses of ethanol (2.5 g/kg) or nicotine (1 or 2 mg/kg) were measured using a test battery consisting of respiration rate, acoustic startle response, Y-maze crosses and rears, heart rate and body temperature. Chronic ethanol-treated animals were tolerant to the effects elicited by a challenge dose of ethanol on four of the six measures and were cross-tolerant to nicotine's effects on the acoustic startle test. Chronic nicotine-treated animals were tolerant to nicotine's effects on five of the six measures and cross-tolerant to ethanol's effects on heart rate and body temperature. Thus, partial cross-tolerance between ethanol and nicotine exists. Chronic nicotine treatment resulted in significant increases in L-[3H]-nicotine binding in six of seven brain regions and in alpha-[125I]-bungarotoxin binding in three of seven brain regions. Chronic ethanol treatment failed to alter the binding of either ligand. Therefore, the cross-tolerance that develops between ethanol and nicotine is not totally dependent on alterations in the number of brain nicotinic receptors.

    2003-10-01

    Patients with predicted severe necrotizing pancreatitis as diagnosed by C-reactive protein (>150 mg/L) and/or contrast-enhanced computed tomography should be managed in the intensive care unit. Prophylactic broad-spectrum antibiotics reduce infection rates and survival in severe necrotizing pancreatitis. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy is a causative therapy for gallstone pancreatitis with impacted stones, biliary sepsis, or obstructive jaundice. Fine needle aspiration for bacteriology should be performed to differentiate between sterile and infected pancreatic necrosis in patients with sepsis syndrome. Infected pancreatic necrosis in patients with clinical signs and symptoms of sepsis is an indication for surgery. Patients with sterile pancreatic necrosis should be managed conservatively. Surgery in patients with sterile necrosis may be indicated in cases of persistent necrotizing pancreatitis and in the rare cases of "fulminant acute pancreatitis." Early surgery, within 14 days after onset of the disease, is not recommended in patients with necrotizing pancreatitis. The surgical approach should be organ-preserving (debridement/necrosectomy) and combined with a postoperative management concept that maximizes postoperative evacuation of retroperitoneal debris and exudate. Minimally invasive surgical procedures have to be regarded as an experimental approach and should be restricted to controlled trials. Cholecystectomy should be performed to avoid recurrence of gallstone-associated acute pancreatitis.

    Full Text Available Nowadays methods used in acute pancreatitis diagnostic do not allow to find the most optimal indications, terms of surgical drainage approaches in surgical treatment of acute pancreatitis. Aim. In order to develop optimal diagnostic and treatment algorithm 316 patients took part in the study. Methods and results. Surgery outcomes were assessed by the next methods: ultrasound, computed tomography. We determined that destructive changes in pancreas in group of sterile pancreatic necrosis were limited. In cases of infected pancreatic necrosis the damage was spread and the disease course was septic. That’s why the operative treatment in cases of sterile pancreatitis has to be used with strict indications such as fermentative peritonitis, acute liquid formations, acute pseudocysts. Conclusion. In such cases miniinvasive surgery is mainly used while in the cases of infected pancreatic necrosis we ought to choose open surgery treatment.

    Full Text Available Alcohol is a known modulator of the innate immune system. Owing to the absence of human studies, alcohol’s effect on circulating cytokine profile remains unclear. We investigated the effect of acute high dose alcohol consumption on systemic cytokine release. After an overnight fasting, alcohol-experienced healthy male volunteers (N=20 aged 25–45 years were given oral ethanol in the form of vodka (4.28 mL/kg which they drank over a period of 30 minutes reaching peak blood alcohol concentration of 0.12% (SD 0.028. Blood samples were obtained prior to alcohol intake as well as 2, 7, and 12 hours thereafter. Serum levels of the inflammatory cytokines IL-1β, IL-1Ra, IL-6, IL-10, IL-17, IFN-γ, MCP-1, and TNF-α were determined by the multibead-based assay. Baseline cytokine levels were not related to BMI, hepatic parameters, electrolytes, glucose, or morning cortisol levels. Within 2 hours of alcohol intake, levels of IL-1Ra were elevated and remained so throughout the assessment period (p for trend = 0.015. In contrast, the levels of the chemokine MCP-1 dropped acutely followed by steadily increasing levels during the observation period (p<0.001. The impact of sustained elevated levels of MCP-1 even after the clearance of blood alcohol content deserves attention.

    Full Text Available Background: Oral consumption of Astragalus hamosus L. (AH seedpod has been widely prescribed in traditional medicine system. However, its toxicity evaluation has never been investigated. Hence, the current study was performed to evaluate the toxicological profile of AH seedpod in acute and subacute assessments based on the OECD-guidelines 425 and 407 in male and female Wistar rats. Methods: In the acute study, ethanolic extract of AH at a single dose of 2000 mg/kg was orally administrated to six female rats. In the subacute assay, AH at the three different oral doses (75, 150 and 300 mg/kg were administrated to both male and female rats for 28 consecutive days. Results: No death or behavioural changes were observed in the treated animals. In subacute test, in both sexes, no changes in organ weights observed. Biochemically, compared to the control, AH at the dose of 300 mg/kg slightly increased (p<0.05 uric acid and creatinine and declined total cholesterol levels in both male and female rats. However, there is no statistically difference in other parameters such as albumin, triglyceride, blood urea, aspartate aminotransferase and alanine aminotransferase between AH treated groups and untreated controls. Hematologic parameters showed that AH at the maximum dose decreased red blood cells count only in male rats. Histopathological evaluation of liver and kidney exhibited no noticeable alterations in AH treated animals. Conclusion: It could be concluded that high excessive and long term consumption of AH may lead to renal dysfunction and deficiency in hematopoietic system.

    The aim of this study is to evaluate the physiological and psychological effect after an electromyographic biofeedback treatment in combination with progressive muscular relaxation training in patients with acute whiplash. Twelve patients with acute whiplash volunteered to participate in a quasi-experimental design and a control group. Two months maximum after car accident, severity levels II and I. previous history of persistent pain or serious previous injury. The groups were randomly divided in two (treatment and waiting list groups). We used electromyographic measures of the trapezius muscles with psychometric tests: Beck Anxiety and Depression Inventory; Oswestry Pain Disability Questionnaire; Visual Analog Scale of Pain; TAMPA Scale for Kinesiophobia. The treatment consisted in electromyographic biofeedback after progressive muscular relaxation training. There were significant intra-group differences before and after treatment in muscular symmetry and subjective pain perception in the treatment group. We achieved a significant change (clinical and statistical) in subjective pain perception and muscular symmetry. This study highlights the importance of multidisciplinary work in acute pain patients and the effectiveness of clinical psychophysiological strategies with acute whiplash patients.

    Naltrexone, a nonspecific opioid antagonist, produces significant changes in ethanol responsivity in rats by rendering the taste of ethanol aversive as well as producing a decrease in voluntary ethanol consumption. The present study investigated the effect of naltrindole, a specific antagonist of delta opioid receptors, on ethanol taste reactivity and ethanol consumption in outbred rats. In the first experiment, rats received acute treatment of naltrexone, naltrindole, or saline followed by the measurement of ethanol consumption in a short-term access period. The second experiment involved the same treatments and investigated ethanol palatability (using the taste-reactivity test) as well as ethanol consumption. Results indicated that treatment with 3 mg/kg naltrexone significantly affected palatability (rendered ethanol more aversive, Experiment 2) and decreased voluntary ethanol consumption (Experiments 1 and 2). The effects of naltrindole were inconsistent. In Experiment 1, 8 mg/kg naltrindole significantly decreased voluntary ethanol consumption but this was not replicated in Experiment 2. The 8 mg/kg dose produced a significant increase in aversive responding (Experiment 2) but did not affect ingestive responding. Lower doses of naltrindole (2 and 4 mg/kg) were ineffective in altering rats' taste-reactivity response to and consumption of ethanol. While these data suggest that delta receptors are involved in rats' taste-reactivity response to ethanol and rats' ethanol consumption, it is likely that multiple opioid receptors mediate both behavioral responses.

    2016-10-01

    Full Text Available The body responds to endotoxins by triggering the acute inflammatory response system to eliminate the threat posed by gram-negative bacteria (endotoxin and restore health. However, an uncontrolled inflammatory response can lead to tissue damage, organ failure, and ultimately death; this is clinically known as sepsis. Mathematical models of acute inflammatory disease have the potential to guide treatment decisions in critically ill patients. In this work, an 8-state (8-D differential equation model of the acute inflammatory response system to endotoxin challenge was developed. Endotoxin challenges at 3 and 12 mg/kg were administered to rats, and dynamic cytokine data for interleukin (IL-6, tumor necrosis factor (TNF, and IL-10 were obtained and used to calibrate the model. Evaluation of competing model structures was performed by analyzing model predictions at 3, 6, and 12 mg/kg endotoxin challenges with respect to experimental data from rats. Subsequently, a model predictive control (MPC algorithm was synthesized to control a hemoadsorption (HA device, a blood purification treatment for acute inflammation. A particle filter (PF algorithm was implemented to estimate the full state vector of the endotoxemic rat based on time series cytokine measurements. Treatment simulations show that: (i the apparent primary mechanism of HA efficacy is white blood cell (WBC capture, with cytokine capture a secondary benefit; and (ii differential filtering of cytokines and WBC does not provide substantial improvement in treatment outcomes vs. existing HA devices.

    Rynn, Moira A; Brawman-Mintzer, Olga

    2004-10-01

    Clinical and epidemiological data suggest that generalized anxiety disorder (GAD) is a chronic illness causing patients to suffer for many years leading to significant distress in daily life functioning. The literature suggests the several conclusions. GAD is a disorder in need of appropriate treatment and often has a chronic course with comorbid conditions, such as major depression and other anxiety disorders. Benzodiazepines, while effective anxiolytic agents acutely, when prescribed for >4 weeks cause rebound anxiety and following prolonged therapy may lead to withdrawal symptoms. Antidepressants cause significant anxiety relief compared with placebo and for psychosocial treatment cognitive-behavioral therapy is an efficacious psychosocial treatment. Many GAD patients are in need of long-term medication management. Furthermore, there is limited data for patients diagnosed with GAD the treatment outcome with the combination of medication and psychotherapy both acutely and long-term; how to best sequence these treatments; for those patients who do not meet remission criteria what is the ideal approach for augmentation; and for patients with treatment-refractory GAD the empirical evidence is lacking on medication switching and augmentation strategies. Research is needed in the area of developing treatment strategies for patients suffering from treatment-refractory GAD. There is still an urgent need to explore treatment combinations and duration strategies in the management of patients suffering with GAD.

    To determine the factors influencing the successful outcome of community treatment for severe acute psychiatric illnesses that are traditionally treated in hospital. All patients from a single electoral ward who were either admitted to hospital or treated at home over a two year period (1 October 1987 to 30 September 1989) were included in the study and their case notes audited. The second year of the study is reported. Electoral ward of Sparkbrook, Birmingham. 99 Patients aged 16-65 with severe acute psychiatric illness. 65 Patients were managed by home treatment alone; 34 required admission to hospital. The location of treatment was significantly (all p less than 0.05) influenced by social characteristics of the patients (marital state, age (in men), ethnicity, and living alone) and by characteristics of the referral (occurring out of hours; assessment taking place at hospital or police station). DSM-III-R diagnosis was more weakly associated with outcome. Violence during the episode was significantly related to admission, although deliberate self harm was not. Home treatment is feasible for most patients with acute psychiatric illness. A 24 hour on call assessment service increases the likelihood of success because admission is determined more strongly by social characteristics of the patient and the referral than by illness factors. Admission will still be required for some patients. A locally based mental health resource centre, a 24 hour on call service, an open referral system, and an active follow up policy increase the effectiveness of a home treatment service.

  13. Microbiology and Treatment of Acute Apical Abscesses

    Rôças, Isabela N.

    2013-01-01

    SUMMARY Acute apical abscess is the most common form of dental abscess and is caused by infection of the root canal of the tooth. It is usually localized intraorally, but in some cases the apical abscess may spread and result in severe complications or even mortality. The reasons why dental root canal infections can become symptomatic and evolve to severe spreading and sometimes life-threatening abscesses remain elusive. Studies using culture and advanced molecular microbiology methods for microbial identification in apical abscesses have demonstrated a multispecies community conspicuously dominated by anaerobic bacteria. Species/phylotypes commonly found in these infections belong to the genera Fusobacterium, Parvimonas, Prevotella, Porphyromonas, Dialister, Streptococcus, and Treponema. Advances in DNA sequencing technologies and computational biology have substantially enhanced the knowledge of the microbiota associated with acute apical abscesses and shed some light on the etiopathogeny of this disease. Species richness and abundance and the resulting network of interactions among community members may affect the collective pathogenicity and contribute to the development of acute infections. Disease modifiers, including transient or permanent host-related factors, may also influence the development and severity of acute abscesses. This review focuses on the current evidence about the etiology and treatment of acute apical abscesses and how the process is influenced by host-related factors and proposes future directions in research, diagnosis, and therapeutic approaches to deal with this disease.

    This report describes a preliminary process design for treating the wastewater from NREL's cellulosic ethanol production process to quality levels required for recycle. In this report Brown and Caldwell report on three main tasks: 1) characterization of the effluent from NREL's ammonia-conditioned hydrolyzate fermentation process; 2) development of the wastewater treatment process design; and 3) development of a capital and operational cost estimate for the treatment concept option. This wastewater treatment design was incorporated into NREL's cellulosic ethanol process design update published in May 2011 (NREL/TP-5100-47764).

    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 a was matched by a comparable decrease in glucose utilization (R 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 a is counterbalanced by equal inhibition of R d ; (2) basal R a and R 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

    Acute gastrointestinal bleeding-massive acute bleeding from gastrointestinal section is one of the most frequent forms of acute abdomen. The mortality degree in emergency surgery is about 10%. It's very difficult to identify the place of bleeding and etiology. The important purpose of this research is to present the cases of acute gastrointestinal bleeding from the patients which were monitored and treated at The University Clinical Center of Kosova-Emergency Center in Pristina. These inquests included 137 patients with acute gastrointestinal bleeding who were treated in emergency center of The University Clinical Center in Pristina for the period from January 2005 until December 2006. From 137 patients with acute gastrointestinal bleeding 41% or 29% was female and 96% or 70.1% male. Following the sex we gained a high significant difference of statistics (p < 0.01). The gastrointestinal bleeding was two times more frequent in male than in female. Also in the age-group we had a high significant difference of statistics (p < 0.01) 63.5% of patients were over 55 years old. The mean age of patients with an acute gastrointestinal bleeding was 58.4 years SD 15.8 age. The mean age for female patients was 56.4 age SD 18.5 age. The patients with arterial systolic pressure under 100 mmHg have been classified as patients with hypovolemic shock. They participate with 17.5% in all prevalence of acute gastrointestinal bleeding. From the number of prevalence 2 {1.5%} patients have been diagnosed with peptic ulcer, 1 {0.7%} as gastric perforation and 1 {0.7%} with intestine ischemia. Abdominal Surgery and Intensive Care 2 or 1.5% died, 1 at intensive care unit and 1 at nephrology. As we know the severe condition of the patients with gastrointestinal bleeding and etiology it is very difficult to establish, we need to improve for the better conditions in our emergency center for treatment and initiation base of clinic criteria.

    Viola tianshanica Maxim, belonging to the Violaceae plant family, is traditionally used in Uighur medicine for treating pneumonia, headache, and fever. There is, however, a lack of basic understanding of its pharmacological activities. This study was designed to observe the effects of the ethanol extract (TSM) from Viola tianshanica Maxim on the inflammation response in acute lung injury (ALI) induced by LPS and the possible underlying mechanisms. We found that TSM (200 and 500 mg/kg) significantly decreased inflammatory cytokine production and the number of inflammatory cells, including macrophages and neutrophils, in bronchoalveolar lavage fluid. TSM also markedly inhibited the lung wet-to-dry ratio and alleviated pathological changes in lung tissues. In vitro, after TSM (12.5-100 μg/ml) treatment to RAW 264.7 cells for 1 h, LPS (1 μg/ml) was added and the cells were further incubated for 24 h. TSM dose-dependently inhibited the levels of proinflammatory cytokines, such as NO, PGE2, TNF-α, IL-6, and IL-1β, and remarkably decreased the protein and mRNA expression of TNF-α and IL-6 in LPS-stimulated RAW 264.7 cells. TSM also suppressed protein expression of p-IκBa and p-ERK1/2 and blocked nuclear translocation of NF-κB p65. The results indicate that TSM exerts anti-inflammatory effects related with inhibition on NF-κB and MAPK (p-ERK1/2) signaling pathways. In conclusion, our data demonstrate that TSM might be a potential agent for the treatment of ALI.

    Both chronic and binge alcohol abuse can be significant risk factors for inflammatory lung diseases such as acute respiratory distress syndrome and chronic obstructive pulmonary disease. However, metabolic basis of alcohol-related lung disease is not well defined, and may include key metabolites of ethanol [EtOH] in addition to EtOH itself. Therefore, we investigated the effects of EtOH, acetaldehyde [ACE], and fatty acid ethyl esters [FAEEs] on oxidative stress, endoplasmic reticulum (ER) stress, AMP-activated protein kinase (AMPK) signaling and nuclear translocation of phosphorylated (p)-NF-κB p65 in primary human airway smooth muscle (HASM) cells stimulated to produce cytokines using LPS exposure. Both FAEEs and ACE induced evidence of cellular oxidative stress and ER stress, and increased p-NF-κB in nuclear extracts. EtOH and its metabolites decreased p-AMPKα activation, and induced expression of fatty acid synthase, and decreased expression of sirtuin 1. In general, EtOH decreased secretion of IP-10, IL-6, eotaxin, GCSF, and MCP-1. However, FAEEs and ACE increased these cytokines, suggesting that both FAEEs and ACE as compared to EtOH itself are proinflammatory. A direct effect of EtOH could be consistent with blunted immune response. Collectively, these two features of EtOH exposure, coupled with the known inhibition of innate immune response in our model might explain some clinical manifestations of EtOH exposure in the lung. - Highlights: • Metabolic basis for EtOH toxicity was studied in human airway smooth muscle (HASM) cells. • In HASM cells, EtOH metabolites were found to be relatively more toxic than EtOH itself. • EtOH metabolites mediate deactivation of AMPK via oxidative stress and ER stress. • EtOH metabolites were found to be more proinflammatory than EtOH itself in HASM cells.

    The Purpose of this research study was to examine the toxicological effects of aqueous: ethanol (1:1) extract of Carissa carandas leaves extracts in rats. Methodolgy: Acute toxicity studies were conducted to check the LD50 values in experimental animals. Autopsy after acute toxicity revealed that no gross changes were observed in organs like liver, spleen, heart and kidney among the animals of group N (control) and S (treated). The appearance of organs of Group S animals was comparable with that of Group N animals. Results: No signs of toxicity and mortality were observed in treated group after sub acute toxicity as compared to the control group. The histopathological studies after subchronic toxicity in doses of 1750 mg/kg (p.o.) and 5000 mg/kg (p.o) showed no toxic effects on organs like liver, heart, kidney and spleen. While chronic toxicity in dose 5000 mg/kg (p.o.) showed some histological changes. (author)

    Acute aortic occlusion (AAO) is a rare disease with high morbidity and mortality. The aim of this study was to describe the results of surgical treatment of acute aortic occlusion and risk factors for mortality. Retrospective review of the clinical history of 29 patients diagnosed and operated on for AAO during 28 years. The following variables were analysed: age, sex, tabaco use, diabetes, chronic renal insufficiency, chronic heart failure, atrial fibrillation, arterial hypertension, symptoms, diagnosis and treatment, 30-day mortality and long-term survival. A univariant analysis was performed of variables related to mortality. Twenty-nine patients were included (18 male) with a mean age of 66,2 years. The aetiology was: embolism (EM) in 11 cases and Thrombosis (TR) in 18 cases. The surgical procedures performed included bilateral transfemoral thrombectomy (14 cases), aorto-bifemoral by-pass (8 cases), axilo uni/bifemoral by-pass (5 cases) and aortoiliac and renal tromboendarterectomy (2 cases). Morbidity included: renal failure (14 cases), mesenteric ischemia (4 cases), cardiac complications (7 cases), respiratory complications (5 cases) and loss of extremity (2 cases). The in-hospital mortality was 21% (EM 0%, TR 21%). The estimated survival at 1.3 and 5 years was 60, 50 and 44% respectively. Age (p=0.032), arterial hypertension (p=0.039) and aetiology of the AAO (p=0.039) were related to mortality. Acute aortic occlusion is a medical emergency with high mortality rates. Acute renal failure is the most common postoperative complication. Copyright © 2012 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    The objective of this study was to verify a possible neuroprotective effect of the ethanolic extract of Erythrina velutina (EEEV). Male Swiss mice were submitted to transient cerebral ischemia by occlusion of both carotid arteries for 30 min and treated for 5 days with EEEV (200 or 400 mg/kg) or Memantine (MEM) 10 mg/kg, with initiation of treatment 2 or 24 h after Ischemia. On the 6th day after the induction of ischemia, the animals were submitted to evaluation of locomotor activity and memory and then sacrificed. The brains were dissected for the removal of the prefrontal cortex (PFC), hippocampus (HC) and striatum (ST) for determination of amino acid concentrations. In the step down and Y-maze tests, ischemia caused damage to the animals and treatment with EEEV or MEM reversed this effect. The animals submitted to ischemia also showed memory deficit in the object recognition test, an effect that was reverted by EEEV400 and MEM10. Amino acid dosage showed an increase in excitatory amino acid concentrations in the PFC of the ischemic animals and this effect was reversed by the treatment with EEEV400/24H. Regarding the inhibitory amino acids, ischemia caused an increase of taurine in the PFC while treatment with MEM10/24H or EEEV400/24H reversed this effect. In HC, an increase in excitatory amino acids was also observed in ischemiated animals having treatment with EEEV200/2H or EEEV400/24H reversed this effect. Similar effect was also observed in the same area in relation to the inhibitory amino acids with treatment with MEM10/24H or EEEV400/24H. In the ST, ischemia was also able to cause an increase in excitatory amino acids that was reversed more efficiently by the treatments with MEM10/24H and EEEV200. Also in this area, an increase of taurine and GABA was observed and only the treatment with EEEV200/2H showed a reversion of this effect. In view of these findings, EEEV presents a neuroprotective effect possibly due to its action on amino acid

    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.

    Ethanol has acute negative inotropic and arrhythmogenic effects. The underlying mechanisms, however, are largely unknown. Sarcoplasmic reticulum Ca 2+ -leak is an important mechanism for reduced contractility and arrhythmias. Ca 2+ -leak can be induced by oxidative stress and Ca 2+ /Calmodulin-dependent protein kinase II (CaMKII). Therefore, we investigated the influence of acute ethanol exposure on excitation-contraction coupling in atrial and ventricular cardiomyocytes. Isolated human atrial and murine atrial or ventricular cardiomyocytes were preincubated for 30 min and then superfused with control solution or solution containing ethanol. Ethanol had acute negative inotropic and positive lusitropic effects in human atrial muscle strips and murine ventricular cardiomyocytes. Accordingly, Ca 2+ -imaging indicated lower Ca 2+ -transient amplitudes and increased SERCA2a activity, while myofilament Ca 2+ -sensitivity was reduced. SR Ca 2+ -leak was assessed by measuring Ca 2+ -sparks. Ethanol induced severe SR Ca 2+ -leak in human atrial cardiomyocytes (calculated leak: 4.60 ± 0.45 mF/F 0 vs 1.86 ± 0.26 in control, n ≥ 80). This effect was dose-dependent, while spontaneous arrhythmogenic Ca 2+ -waves increased ~5-fold, as investigated in murine cardiomyocytes. Delayed afterdepolarizations, which can result from increased SR Ca 2+ -leak, were significantly increased by ethanol. Measurements using the reactive oxygen species (ROS) sensor CM-H 2 DCFDA showed increased ROS-stress in ethanol treated cells. ROS-scavenging with N-acetylcysteine prevented negative inotropic and positive lusitropic effects in human muscle strips. Ethanol-induced Ca 2+ -leak was abolished in mice with knockout of NOX2 (the main source for ROS in cardiomyocytes). Importantly, mice with oxidation-resistant CaMKII (Met281/282Val mutation) were protected from ethanol-induced Ca 2+ -leak. We show for the first time that ethanol acutely induces strong SR Ca 2+ -leak, also altering

    Organophosphorus compounds (OPCs) have a wide variety of applications and are a serious threat for self-poisoning, unintentional misuse, terrorist attack, occupational hazard and warfare attack. The present standard treatment has been reported to be unsatisfactory. Many novel approaches are being used and tested for acute organophosphorus (OP) poison treatment. The bioscavenger concept captured high attention among the scientific community during the last few decades. Other approaches like alkalinisation of blood plasma/serum and use of weak inhibitors against strong inhibitors, though it showed promising results, did not get such wide attention. The introduction of a novel broad-spectrum oxime has also been in focus. In this mini-review, an update of the overview of four different approaches has been discussed. The standard therapy that is atropine+oxime+benzodiazepine along with supportive measures will continue to be the best option with only the replacement of a single oxime to improve its broad-spectrum efficacy.

    Alcohol-based hand sanitizers have become widely available because of widespread usage in schools, hospitals, and workplaces and by consumers. We report what we believe is the first unintentional ingestion in a small child producing significant intoxication. A 4-year-old 14-kg girl was brought to the emergency department with altered mental status after a history of ingesting an alcohol-based hand sanitizer. Physical examination revealed an obtunded child with periods of hypoventilation and a hematoma in the central portion of her forehead from a fall at home that occurred after the ingestion. Abnormal vital signs included a heart rate of 139 beats/min and temperature of 96.3 degrees F, decreasing to 93.6 degrees F. Abnormal laboratory values consisted of potassium of 2.6 mEq/L and a serum alcohol of 243 mg/dL. A computed tomography scan of her brain without contrast showed no acute intracranial abnormality. A urine drug screen for common drugs of abuse was reported as negative. The child was intubated, placed on mechanical ventilation, and admitted for medical care. She recovered over the next day without sequelae. As with other potentially toxic products, we would recommend caution and direct supervision of use when this product is available to young children.

  9. Fibroblast growth factor 21 (FGF21 is robustly induced by ethanol and has a protective role in ethanol associated liver injury

    Conclusions: Acute or binge ethanol consumption significantly increases circulating FGF21 levels in both humans and mice. However, FGF21 does not play a role in acute ethanol clearance. In contrast, chronic ethanol consumption in the absence of FGF21 is associated with significant liver pathology alone or in combination with excess mortality, depending on the type of diet consumed with ethanol. This suggests that FGF21 protects against long term ethanol induced hepatic damage and may attenuate progression of alcoholic liver disease. Further study is required to assess the therapeutic potential of FGF21 in the treatment of alcoholic liver disease.

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

    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.

    Morus alba L. (white mulberry) is used in traditional medicine worldwide, including Brazil. The leaves of this plant are used to treat inflammatory disorders. Universal interest in this plant necessitates studies on the toxicological safety and scientific substantiation of the medicinal properties of M. alba. In previous work, we investigated the acute toxicity of orally administered M. alba ethanol extract in mice. This work was designed to investigate the ethanol extract obtained from M. alba leaves for acute toxicity when intraperitoneally administered, in vivo genotoxicity, and potential to reduce acute inflammation. In order to further investigate the constituents of the extract, we also obtained the high-performance liquid chromatography (HPLC) fingerprint of the extract. Phytochemical analysis by thin layer chromatography (TLC) was performed and the results were used to obtain the HPLC fingerprint. Acute toxicity of 300 and 2000mg/kg b.w. i.p. doses administered to mice for 14 days was evaluated. Genotoxicity was evaluated by counting the number of micronucleated polychromatic erythrocytes in the blood of mice that either received or did not receive the extract at 75, 150 and 300mg/kg b.w. per os. The anti-inflammatory effect of the same doses administered per os was investigated using the carrageenan air pouch model. The TLC analysis of the extract revealed the presence of a remarkable amount of flavonoids and cinnamic acids. The HPLC fingerprint showed the presence of one major peak corresponding to chlorogenic acid and two smaller peaks corresponding to flavonoids. In the toxicity assays, there were no deaths or deviations in behavior of treated mice as compared to the control at any dose. However, biochemical, hematological, and histological analyses showed that intraperitoneal injection caused several forms of damage to the mice, which were not observed in case of oral administration, studied in our previous work. Oral administration of the extract did

    2014-01-01

    Acute recurrent pancreatitis (ARP) refers to a clinical entity characterized by episodes of acute pancreatitis which occurs on more than one occasion. Recurrence of pancreatitis generally occurs in a setting of normal morpho-functional gland, however, an established chronic disease may be found either on the occasion of the first episode of pancreatitis or during the follow-up. The aetiology of ARP can be identified in the majority of patients. Most common causes include common bile duct stones or sludge and bile crystals; sphincter of oddi dysfunction; anatomical ductal variants interfering with pancreatic juice outflow; obstruction of the main pancreatic duct or pancreatico-biliary junction; genetic mutations; alcohol consumption. However, despite diagnostic technologies, the aetiology of ARP still remains unknown in up to 30% of cases: in these cases the term “idiopathic” is used. Because occult bile stone disease and sphincter of oddi dysfunction account for the majority of cases, cholecystectomy, and eventually the endoscopic biliary and/or pancreatic sphincterotomy are curative in most of cases. Endoscopic biliary sphincterotomy appeared to be a curative procedure per se in about 80% of patients. Ursodeoxycholic acid oral treatment alone has also been reported effective for treatment of biliary sludge. In uncertain cases toxin botulin injection may help in identifying some sphincter of oddi dysfunction, but this treatment is not widely used. In the last twenty years, pancreatic endotherapy has been proven effective in cases of recurrent pancreatitis depending on pancreatic ductal obstruction, independently from the cause of obstruction, and has been widely used instead of more aggressive approaches.

    Ethanol (EtOH) intoxication inhibits glucose transport and decreases overall brain glucose metabolism; however, humans with long-term EtOH consumption were found to have a significant increase in [1- 11 C]-acetate uptake in the brain. The relationship between the cause and effect of [1- 11 C]-acetate kinetics and acute/chronic EtOH intoxication, however, is still unclear. [1- 11 C]-acetate positron emission tomography (PET) with dynamic measurement of K 1 and k 2 rate constants was used to investigate the changes in acetate metabolism in different brain regions of rats with acute or chronic EtOH intoxication. PET imaging demonstrated decreased [1- 11 C]-acetate uptake in rat brain with acute EtOH intoxication, but this increased with chronic EtOH intoxication. Tracer uptake rate constant K 1 and clearance rate constant k 2 were decreased in acutely intoxicated rats. No significant change was noted in K 1 and k 2 in chronic EtOH intoxication, although 6 of 7 brain regions showed slightly higher k 2 than baseline. These results indicate that acute EtOH intoxication accelerated acetate transport and metabolism in the rat brain, whereas chronic EtOH intoxication status showed no significant effect. In vivo PET study confirmed the modulatory role of EtOH, administered acutely or chronically, in [1- 11 C]-acetate kinetics and metabolism in the rat brain. Acute EtOH intoxication may inhibit the transport and metabolism of acetate in the brain, whereas chronic EtOH exposure may lead to the adaptation of the rat brain to EtOH in acetate utilization. [1- 11 C]-acetate PET imaging is a feasible approach to study the effect of EtOH on acetate metabolism in rat brain. Copyright © 2017 by the Research Society on Alcoholism.

    Rhinosinusitis is a common health complaint that is often seen by primary care physicians and otolaryngologists in the United States. The complicated anatomy of the paranasal sinuses, as well as the multiple etiologies, contributes to the complexity that one often faces in trying to ameliorate or eradicate this disease in affected individuals. A full understanding of the fundamentals of rhinosinusitis, as well as the treatment options available for the different types, is important. It is very important for the physician to take an organized, step-by-step approach to the management of each patient with this complicated disease. As most cases of rhinosinusitis presenting to the generalist's office will be of viral origin, antibiotics should not be given unless the patient has purulent rhinorrhea or worsening symptoms lasting more than 5 days, or total symptoms lasting longer than 10 days. When medical treatment fails or is incomplete, adjunctive surgical treatment becomes an option. Generally, the symptoms that are most helped by surgery include persistent headaches, nasal obstruction, and recurrent or persistent purulent rhinorrhea unresponsive to medical management. Appropriate and timely referral for specialty care will result in the definitive management of recalcitrant rhinosinusitis when medical management alone fails or in cases where a complication or malignancy is suspected. This article reviews the current understanding of the anatomy, pathophysiology, classification, diagnosis, and potential complications of rhinosinusitis. It also describes the current approach to the treatment of both acute and chronic rhinosinusitis.

    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 caused by drug and

    The authors present 7 patients who suffered iliac artery rupture over a 2 year period. In 5 patients, the rupture was iatrogenic: 4 cases were secondary to balloon angioplasty for iliac artery stenosis and 1 occurred during coronary angioplasty. In the last 2 patients, the rupture was secondary to iliac artery mycotic aneurysm. Direct placement of a stent-graft was performed in all cases, which was dilated until extravasation was controlled. Placement of the stent-graft was successful in all the cases, without any complications. The techniques used, results, and mid-term follow-up are presented. In conclusion, endovascular placement of a stent-graft is a quick, minimally invasive, efficient, and safe method for emergency treatment of acute iliac artery rupture, with satisfactory short- and mid-term results

  19. 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.

    Taraxacum coreanum Nakai has been traditionally used for treating inflammatory diseases including gastrointestinal diseases. We studied whether water extracts of Taraxacum coreanum Nakai (TCN) had a protective effect on acute and chronic gastritis induced by ethanol/HCl in an animal model of gastritis and its mechanism was also explored. In the acute study, rats were orally administered 0.15g/mL dextrin (normal-control), 0.15g/mL dextrin (control), 0.05g/mL TCN (TCN-L), 0.15g/mL TCN (TCN-H), or 0.01g/mL omeprazole (orally; positive-control), followed by oral administration of 1mL of 60% ethanol plus 150mM HCl (inducer). In the chronic study, rats were administered 10% diluted inducer in drinking water, and 0.6% dextrin, 0.2% or 0.6% TCN, and 0.05% omeprazole were administered in chow for 4 weeks. Acid content, gastric structure, oxidative stress, and markers of inflammation in the stomach tissue were measured at the end of experiment. Acute and chronic ethanol/HCl administration caused the inner layer of the stomach to redden, hemorrhage, and edema in the control group; TCN-H reduced these symptoms more effectively than did the omeprazole positive-control. Acid production and total acidity in the stomach increased in the control group, which was markedly suppressed by omeprazole. TCN also reduced the acid production and acidity, but not to the same degree as omeprazole. H-E and PAS staining revealed that in the inner layer of the stomach, cellular structure was disrupted, with an increased nuclear size and thickness, disarrangement, and decreased mucin in the control group. TCN prevented the cellular disruption in the inner layer, and TCN-H was more effective than the positive-control. This was associated with oxidative stress and inflammation. TCN dose-dependently reduced the infiltration of mast cells and TNF-α expression in the inner layer of the stomach, and decreased lipid peroxides by increasing superoxide dismutase and glutathione peroxidase expression.

    Intranodular ethanol injection has been used for the past 10 years as an efficient modality for treating patients with thyroid nodules. Several studies have reported the success of this therapy in autonomous and cystic nodules and, more recently, in cold benign nodules. To evaluate the efficacy of this therapeutic modality on the treatment of autonomous and cystic thyroid nodules. 42 patients (26 with cystic and 16 with autonomous nodules) were treated with ultrasound guided intranodular 99% ethanol injection and followed for 6 months. No major complications were observed during or after treatment, however, most of the patients reported slight to moderate pain and/or discomfort after the injection. Most of the nodules showed reduction after the treatment. Autonomous nodules had a mean reduction of 50.3% and cystic nodules of 69.3%. No significant differences in pretreatment serum total T3, total T4 or TSH were observed among the patients in the cystic group. Patients in the autonomous group with hyperfunctioning nodules showed a decrease in serum total T3, total T4 and an increase in serum TSH levels, hence, proving the effectiveness of this therapy. Intranodular ethanol injection is a safe and efficient treatment for autonomous and cystic nodules of the thyroid.

    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.

    Liver haemodynamics and liver function were measured in 34 alcoholic cirrhotic men before entry and after 12 months (median) in a double-blind, placebo-controlled study on the effect of oral testosterone treatment (200 mg t.i.d.). Comparing data at entry with those at follow-up in the total patient......, testosterone-treated patients did not differ significantly from placebo-treated patients regarding any of the measured variables. No significant relationships could be demonstrated between ethanol consumption and liver haemodynamics and liver function, but the number of patients consuming more than 100 g...... ethanol per day decreased significantly (P less than 0.001) from 22 (65%) before entry to one (3%) during follow-up. In conclusion, oral testosterone treatment of men with alcoholic cirrhosis does not explain the significant improvement of liver haemodynamics and function observed in this study. However...

    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.

    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. Published by Elsevier Ltd.

    This study was designed to investigate physicochemical characterization of the oil extracted from foxtail millet bran (FMBO), and the antioxidant and hepatoprotective effects against acute ethanol-induced hepatic injury in mice. GC-MS analysis revealed that unsaturated fatty acids (UFAs) account for 83.76% of the total fatty acids; in particular, the linoleic acid (C18:2) is the predominant polyunsaturated fatty acid (PUFA), and the compounds of squalene and six phytosterols (or phytostanols) were identified in unsaponifiable matter of FMBO. The antioxidant activity examination of FMBO in vitro showed highly ferric-reducing antioxidant power and scavenging effects against DPPH· and HO· radicals. Furthermore, the protective effect of FMBO against acute hepatic injuries induced by ethanol was verified in mice. In this, intragastric administration with different dosages of FMBO in mice ahead of acute ethanol administration could observably antagonize the ethanol-induced increases in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), and the hepatic malondialdehyde (MDA) levels, respectively, along with enhanced hepatic superoxide dismutase (SOD) levels relative to the control. Hepatic histological changes were also observed and confirmed that FMBO is capable of attenuating ethanol-induced hepatic injury.

    Acute thallium poisoning rarely occurs but is a serious and even fatal medical condition. Currently, patients with acute thallium poisoning are usually treated with Prussian blue and blood purification therapy. However, there are few studies about these treatments for acute thallium poisoning. Nine patients with acute thallium poisoning from 1 family were treated successfully with Prussian blue and different types of blood purification therapies and analyzed. Prussian blue combined with sequential hemodialysis, hemoperfusion and/or continuous veno-venous hemofiltration were effective for the treatment of patients with acute thallium poisoning, even after delayed diagnosis. Blood purification therapies help in the clearance of thallium in those with acute thallium poisoning. Prussian blue treatment may do the benefit during this process.

    Tumor-induced osteomalacia is a rare condition usually caused by benign mesenchymal tumors. When the tumor can be found, patients are usually managed by wide excision of the tumor. We report a 51-yr-old male with clinical and biochemical evidence of tumor-induced osteomalacia caused by a mesenchymal tumor in the right iliac bone. He declined surgery and appears to have been successfully managed by computed tomography-guided percutaneous ethanol ablation and percutaneous cryoablation. Our patient appears to have had an excellent clinical and biochemical response to computed tomography-guided percutaneous ethanol ablation and percutaneous cryoablation. We found one prior case of image-guided ablation using radiofrequency ablation for tumor-induced osteomalacia. Although the standard treatment for tumor-induced osteomalacia is wide excision of the tumor, image-guided ablation may be an option in patients who cannot have appropriate surgery or who decline surgery.

    To evaluate the histological changes after transepithelial corneal crosslinking (CXL) using partial thickness excimer laser ablation or epithelial ethanol application in an experimental rabbit study. Right eyes of twenty-four rabbits were studied. Four eyes received total epithelial debridement (group I). Four eyes received partial thickness epithelial ablation with excimer laser (group II). Twelve eyes were treated with different durations (30s and 60s) and concentrations (18% to 48%) of ethanol (group III). Riboflavin was applied for 30min intervals along with topical proparacaine drops with benzalkonium chloride, and 370 nm irradiation was performed for 30min, while riboflavin was instilled every 3min. Four eyes (group IV) received 48% ethanol for 30s without riboflavin and irradiation. Eyes were collected after 24h and examined histologically. All eyes in group I showed keratocyte loss in the superficial 300 µ of corneal storma. In group II, 1-4 layers of epithelium were preserved and no keratocyte loss occurred. In group III, CXL after treatment with ethanol up to 24% concentration and up to 60s revealed no keratocyte loss. CXL after treatment with 48% and higher ethanol concentrations yielded keratocyte loss in the superficial 200 µ to 300 µ of cornea. Incomplete excimer laser ablation of the epithelium or treatment with ethanol up to 24% concentration and up to 60s duration yielded no stromal keratocyte loss. To get the same histological appearance seen in epithelial debridement group, partial thickness excimer laser epithelial ablation or ethanol application is not adequate for transepithelial CXL.

    The binding of 3 H-ouabain to human erythrocytes was analyzed in a population of hospitalized male ethanol addicted patients under long term digitalis treatment. In the non-alcoholic patient group the long term digitalis treatment induced an increase in Bmax and Kd values; such modification was not observed in the alcoholic patients. Chronic alcohol intake itself induced an increase in 3 H-ouabain kinetic parameters. These observations confirm that ouabain binding to human erythrocytes is subject to pharmacological and toxicological regulation and that adaptive changes in peripheral tissues can be useful in predicting possible parallel modifications in other less accessible tissues. 22 references, 1 table

    Full Text Available Insoluble fiber (IF recovered from the enzyme-assisted aqueous extraction process (EAEP of soybeans is a fraction rich in carbohydrates and proteins. It can be used to enhance ethanol production in an integrated corn-soy biorefinery, which combines EAEP with traditional corn-based ethanol processing. The present study evaluated IF as a substrate for ethanol production. The effects of treatment of IF (soaking in aqueous ammonia (SAA, liquid hot water (LHW, and enzymatic hydrolysis, primarily simultaneous saccharification and co-fermentation (SSCF, as well as scaling up (250 mL to 60 L on ethanol production from IF alone or a corn and IF slurry were investigated. Enzymatic hydrolysis (pectinase, cellulase, and xylanase, each added at 5% soy solids during simultaneous saccharification and fermentation/SSCF was the best treatment to maximize ethanol production from IF. Ethanol yield almost doubled when SSCF of IF was performed with Saccharomyces cerevisiae and Escherichia coli KO11. Addition of IF in dry-grind corn fermentation increased the ethanol production rate (~31%, but low ethanol tolerance of E. coli KO11 was a limiting factor for employing SSCF in combination corn and IF fermentation. Nonlinear Monod modeling accurately predicted the effect of ethanol concentration on E. coli KO11 growth kinetics by Hanes-Woolf linearization. Collectively, the results from this study suggest a potential of IF as a substrate, alone or in dry-grind corn fermentation, where it enhances the ethanol production rate. IF can be incorporated in the current bioethanol industry with no added capital investment, except enzymes.

    . 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.

    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.

    Renewable energy sources have received increased interest from the international community with biomass being one of the oldest and the most promising ones. In the concept of exploitation of agro-industrial residues, the present study investigates the pre-treatment and ethanol fermentation potential of the olive pulp, which is the semi solid residue generated from the two-phase processing of the olives for olive oil production. Wet oxidation and enzymatic hydrolysis have been applied aiming at the enhancement of carbohydrates' bioavailability. Different concentrations of enzymes and enzymatic durations have been tested. Both wet oxidation and enzymic treatment were evaluated based on the ethanol obtained in a subsequent fermentation step by Saccharomyces cerevisiae and Thermoanaerobacter mathranii. It was found that a four-day hydrolysis time was adequate for a satisfactory release of glucose and xylose. The combination of wet oxidation and enzymatic hydrolysis resulted in the glucose and xylose concentration increase of 138 and 444%, respectively, compared to 33 and 15% with only enzymes added. However, the highest ethanol production was obtained when only enzymic pre-treatment was applied, implying that wet oxidation is not a recommended pre-treatment process for olive pulp at the conditions tested. It was also showed that increased dry matter concentration did not have a negative effect on the release of sugars, indicating that the cellulose and xylan content of the olive pulp is relatively easily available. The results of the experiments in batch processes clearly emphasize that the simultaneous saccharification and fermentation (SSF) mode is advantageous in comparison with the separate hydrolysis and fermentation (SHF) mode concerning process contamination.

    Full Text Available Context: Since ancient times diarrhoea has been a highly fatal disease and even today diarrhoea, the topic of this review, is a problem affecting millions of people around the world despite the efforts of governments and professionals from the medical area. Worldwide the most common cause of children’s death is diarrhoea. Evidence Acquisition: Diarrhoea disorders generally appear with watery stools, sometimes mixed with blood, accompanied by abdominal pain, vomiting and fever. The symptoms depend on the content and distribution of body fluid, daily water requirements and physiological water loss in connection with age through sweating, urination and breathing, the degree of fluid and electrolyte loss in the liquid stool. Results: Several effective interventions have been introduced as part of diarrhoea management in the last two decades such as oral rehydration solution, zinc supplementation, vitamin A supplementation and oral administration of antibiotics and vaccines. To reduce the mortality rate, control of safe drinking water, good sanitation and vaccination against typhoid and cholera are recommended, especially in high-risk populations. Probiotics have been proposed, after more than a half of century, as additional therapy in the treatment of acute diarrhoea. Several probiotic strains showed benefit in meta-analyses of randomised controlled trials. Conclusions: Due to the high level of evidence available, the term "oral bacterio therapy", used for decades in the prevention and the rapyof gastroenteritis in the growing age and adults, has expanded, but probiotics are acquiring significant scientific value based on theresults from human trials. The future of probiotics depends on further explanation/elucidation of basic mechanisms, allowing scientists and physicians to maximize their health benefits.

    Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

    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

    Thiamine and benfotiamine are vitamin B1 and pro-vitamin B1 substances, respectively. Vitamin B1 plays an essential role in energy metabolism, and its deficiency leads to neurologic and cardiovascular pathologies, as seen in alcoholics. This study presents new data about the effects of thiamine hydrochloride or benfotiamine treatment given to rats with acute alcohol intoxication, on the distribution of thiamine and its phosphate esters in liver, plasma and erythrocytes. The treatments were effective in increasing thiamine levels in plasma, erythrocytes and liver cells. The benfotiamine-treated group had its total plasma thiamine increased by 100%. In erythrocytes, thiamine levels were 4- and 25-fold higher in the groups treated with thiamine and benfotiamine, respectively, compared with the untreated groups. Liver thiamine was increased by 60% in the treated groups compared with the untreated groups. Thus, we verified the high bioavailability especially of benfotiamine within 6h of ethanol administration. Copyright © 2013 Elsevier B.V. All rights reserved.

    Acute aortic syndromes (AAS) are life-threatening vascular conditions of the thoracic aorta presenting with acute pain as the leading symptom in most cases. The incidence is approximately 3-5/100,000 in western countries with increase during the past decades. Clinical suspicion for AAS requires immediate confirmation with advanced imaging modalities. Initial management of AAS addresses avoidance of progression by immediate medical therapy to reduce aortic shear stress. Proximal symptomatic lesions with involvement of the ascending aorta are surgically treated in the acute setting, whereas acute uncomplicated distal dissection should be treated by medical therapy in the acute period, followed by surveillance and repeated imaging studies. Acute complicated distal dissection requires urgent invasive treatment and thoracic endovascular aortic repair has become the treatment modality of choice because of favorable outcomes compared to open surgical repair. Intramural hematoma, penetrating aortic ulcers, and traumatic aortic injuries of the descending aorta harbor specific challenges compared to aortic dissection and treatment strategies are not as uniformly defined as in aortic dissection. Moreover these lesions have a different prognosis. Once the acute period of aortic syndrome has been survived, a lifelong medical treatment and close surveillance with repeated imaging studies is essential to detect impending complications which might need invasive treatment within the short-, mid- or long-term.

    Severe acute lead intoxications are rare and are associated with accidental or purposeful ingestion. There were only few cases of severe to fatal poisonings reported in literature in children. We report a case of acute lead intoxication in a child with extremely high lead blood level of 20.4 micromol/L (422.7 microg/dL), who was treated with chelation and in whom significant organ dysfunction did not develop. Documented significant high level above 3.37 micromol/L (corresponding to 70 microg/dL) in this patient persisted for approximately 24 h. Adequate, single or combined chelatation therapy in early phase of acute lead poisoning is essential for the further patient's outcome.

    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.

    The number of lymphocytes of various subsets were not significantly changed by the ethanol exposure except those showing activation markers which were reduced. The percentage of peripheral blood cells showing markers for macrophage functions and their activation were significantly reduced after binge use of ethanol. Ethanol retarded suppression of cells by retroviral infection. However by 25 weeks of infection there was a 8.6% survival in the ethanol fed mice infected with retrovirus which was much less than virally infected controls. Morphine treatment also increased the percentage of cells with markers for macrophages and activated macrophages in virally infected mice, while suppressing them in uninfected mice. The second and third morphine injection series suppressed lymphocyte T-helper and T-suppressor cells, but not total T cells. However, suppression by morphine was significantly less during retroviral disease than suppression caused by the virus only. At 25 weeks of infection 44.8% of morphine treated, infected mice survived.

    Turmeric ( Curcuma longa ) is a widely used spice that has various biological effects, and aqueous extracts of turmeric exhibit potent antioxidant activity and anti-inflammatory activity. Bisacurone, a component of turmeric extract, is known to have similar effects. Oxidative stress and inflammatory cytokines play an important role in ethanol-induced liver injury. This study was performed to evaluate the influence of a hot water extract of C. longa (WEC) or bisacurone on acute ethanol-induced liver injury. C57BL/6 mice were orally administered WEC (20 mg/kg body weight; BW) or bisacurone (60 µg/kg BW) at 30 min before a single dose of ethanol was given by oral administration (3·0 g/kg BW). Plasma levels of aspartate aminotransferase and alanine aminotransferase were markedly increased in ethanol-treated mice, while the increase of these enzymes was significantly suppressed by prior administration of WEC. The increase of alanine aminotransferase was also significantly suppressed by pretreatment with bisacurone. Compared with control mice, animals given WEC had higher hepatic tissue levels of superoxide dismutase and glutathione, as well as lower hepatic tissue levels of thiobarbituric acid-reactive substances, TNF-α protein and IL-6 mRNA. These results suggest that oral administration of WEC may have a protective effect against ethanol-induced liver injury by suppressing hepatic oxidation and inflammation, at least partly through the effects of bisacurone.

  18. Effect of acute ethanol on beta-endorphin secretion from rat fetal hypothalamic neurons in primary cultures

    Energy Technology Data Exchange (ETDEWEB)

    Sarkar, D.K.; Minami, S. (Washington State Univ., Pullman (USA))

    1990-01-01

    To characterize the effect of ethanol on the hypothalamic {beta}-endorphin-containing neurons, rat fetal hypothalamic neurons were maintained in primary culture, and the secretion of {beta}-endorphin ({beta}-EP) was determined after ethanol challenges. Constant exposure to ethanol at doses of 6-50 mM produced a dose-dependent increase in basal secretion of {beta}-EP from these cultured cells. These doses of ethanol did not produce any significant effect on cell viability, DNA or protein content. The stimulated secretion of {beta}-EP following constant ethanol exposure is short-lasting. However, intermittent ethanol exposures maintained the ethanol stimulatory action on {beta}-EP secretion for a longer time. The magnitude of the {beta}-EP response to 50 mM ethanol is similar to that of the {beta}-EP response to 56 mM of potassium. Ethanol-stimulated {beta}-EP secretion required extracellular calcium and was blocked by a calcium channel blocker; a sodium channel blocker did not affect ethanol-stimulated secretion. These results suggest that the neuron culture system is a useful model for studying the cellular mechanisms involved in the ethanol-regulated hypothalamic opioid secretion.

    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. • Percutaneous chemonucleolysis using ethanol gel (PCEG) is feasible on an outpatient basis. • PCEG improves disc-related radicular pain refractory to conservative treatment. • PCEG is feasible on an outpatient basis. • Failure of PCEG does not interfere with subsequent spinal surgery.

Four eyes received total epithelial debridement (group I. Four eyes received partial thickness epithelial ablation with excimer laser (group II. Twelve eyes were treated with different durations (30s and 60s and concentrations (18% to 48% of ethanol (group III. Riboflavin was applied for 30min intervals along with topical proparacaine drops with benzalkonium chloride, and 370 nm irradiation was performed for 30min, while riboflavin was instilled every 3min. Four eyes (group IV received 48% ethanol for 30s without riboflavin and irradiation. Eyes were collected after 24h and examined histologically.RESULTS: All eyes in group I showed keratocyte loss in the superficial 300 µ of corneal storma. In group II, 1-4 layers of epithelium were preserved and no keratocyte loss occurred. In group III, CXL after treatment with ethanol up to 24% concentration and up to 60s revealed no keratocyte loss. CXL after treatment with 48% and higher ethanol concentrations yielded keratocyte loss in the superficial 200 µ to 300 µ of cornea.CONCLUSION: Incomplete excimer laser ablation of the epithelium or treatment with ethanol up to 24% concentration and up to 60s duration yielded no stromal keratocyte loss. To get the same histological appearance seen in epithelial debridement group, partial thickness excimer laser epithelial ablation or ethanol application is not adequate for transepithelial CXL.

    Transcatheter arterial chemoembolization (TACE) and subsequent percutaneous ethanol injection (PEI) was attempted in 8 patients with 9 hepatocellular carcinoma (HCCs) for complete tumor necrosis of HCCs less than 5 cm in greatest diameter. PEI was performed with 2-8 ml of absolute (99.9%) ethanol two weeks after TACE under CT or ultrasound guidance. For each patient PEI was done twice to four times within 4-10 days of each procedure. After completion of a series of PEI, follow up examination (range: 3 months-1.5 year period) was done with angiography, CT or ultrasound and correlated with serum alpha-fetoprotein (AFP) level. On follow up angiograms, the lesions completely disappeared or decreased in size without tumor vessels or staining in 5 of 6 patients. On follow up CT of 6 patients, the lipiodol-laden HCCs were surrounded by non-enhancing low density and the lesion sizes were slightly decreased or not changed. These are suggestive of necrosis of tumor itself and adjacent liver parenchyma. The tumors could not be detected on follow up ultrasound examination in 2 patients. Serum AFP was decreased in 7 patients and was well corresponded to the results of imaging modalities. The authors concluded that the combined TACE and PEI is an appropriate treatment for small HCCs having high surgical risks.

    Objective: To evaluate the safety and efficacy of CT-guided percutaneous ethanol injection (CT-PEI) in the treatment of thyroid adenoma. Methods: Fifty-four patients with 73 nodules were included in the study. Thyroid adenoma was confirmed by pathology. The serum level T3, T4 and TSH were normal in all cases. CT-PEI (0.3-2.5 ml ethanol/cm 3 nodular tissue) was given for 115 times (mean 1.58 +- 0.78 times/nodule). Results: Complete cure was observed in 37 nodules (50.7%). In 28 nodules (38.3%) volume reduction was greater than 80%. A significant nodule reduction (50%-80%) was observed in 7 nodules. Only 1 (1.4%) nodule volume reduction was 28.9%. Apart from 1 case of transient dysphonia and 2 cases of mild pain and burning sensation, no side effect was observed. Conclusion: CT-PEI is a safe and effective therapeutic procedure with few side effects for thyroid adenoma

    In this report we describe an unusual patient with hyperfunctioning thyroid adenoma in whom percutaneous ethanol injection (p.e.i.) therapy was followed by typical Graves' disease. His history revealed the presence of a sister with Hashimoto's thyroiditis. 99-mTc thyroid scintiscan showed focal uptake in the nodule, with suppression of extranodular parenchyma. P.e.i. therapy was followed by the development of severe hyperthyroidism. One month after a second p.e.i. cycle, recurrence of hyperthyroidism associated with diffuse 99-mTc uptake by the gland was observed. TSH-receptor and thyroglobulin autoantibodies were undetectable before p.e.i. therapy, appeared during the first cycle, and showed a further increase after the second p.e.i. therapy cycle. Though spontaneous switch to Graves' disease cannot be excluded in patients with toxic nodules, the massive release of thyroid materials from follicular cells, among these TSH-receptor antigenic components partially denatured by ethanol, may indeed trigger an autoimmune response to the TSH-receptor, thus accounting for this observation. Patients with possible autoimmune disposition, as selected by familiar history and/or laboratory markers should be carefully monitored during p.e.i. treatment.

    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.

    Severe acute malnutrition is a serious health problem among children in low-income countries. Particularly malnourished children requiring in-hospital treatment are at high risk of dying. This dissertation investigates possible reasons for this high mortality, by following a group of 120 children...... during their in-hospital treatment of severe acute malnutrition at Mwanamugimu Nutrition Unit in Kampala, Uganda. We assessed how malnutrition affected the children’s immune system, by measuring the size of their thymus gland with ultrasound. We examined characteristics of children with the serious form...... of malnutrition, Kwashiorkor, where the children develop oedema. Finally, we explored symptoms, findings or treatments given that were associated with a higher risk of death in the children. Hopefully, these findings may contribute to improving the treatment offered to children with severe acute malnutrition....

    The aim of our study was to define the long-term efficacy and safety of percutaneous ethanol injection (PEI) for the treatment of autonomous thyroid nodule (ATN), and to optimise the clinical usefulness of such a therapy. We treated 132 patients with ATN (30 M and 102 F, aged 47.5+/-12.9 years; mean+/-SD), in case other established treatments were refused or contraindicated. Eighty-five patients were affected by toxic adenoma and 47 suffered from pre-toxic nodules. Ethanol was administered weekly under sonographic control, in 7 sessions (range 2-16). During PEI treatment, 26 toxic elderly patients were treated with methimazole and propranolol. Three possible outcomes were identified for statistical analysis: failure (persistent suppression of extra nodular tissue uptake, along with elevated free thyroid hormone and undetectable TSH levels); partial cure (normal free thyroid hormone and low/undetectable TSH levels); complete cure (normal thyroid hormone and TSH levels; restored extra nodular uptake). The patients were followed for up to 8.5 years (median 76 months). PEI therapy was well tolerated by all patients though a mild to moderate local pain occurred in about 30% of sessions. Complete cure was achieved in all pre-toxic patients and in 60 (70.6%) patients with toxic adenoma, while partial cure was observed in 11 cases (12.9%) and failure in 14 (16.5%). A significant shrinkage of nodule volume was observed in all patients (p = 0.0001), while those with toxic nodules larger than 30 mL showed a significantly lower response rate to PEI (p thyroid adenoma where therapy is least necessary- despite the nodule volume. Though ethanol injection therapy of toxic thyroid nodules may be troublesome for the need of multiple sessions, it appears an effective alternative procedure in patients at poor surgical risk, and in younger patients in whom radioiodine is contraindicated. Since a special technical skill in intervention procedures is required, PEI therapy may be suitable

    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

    Rice hulls are potential low-cost feedstocks for fuel ethanol production in many countries. In this work, the dilute-acid pre-treatment of artisan rice hulls was investigated using a central composite rotatable experimental design. The experimental variables were temperature (140-210 C), biomass load (5-20%) and sulphuric acid concentration (0.5-1.5 g per 100 g of reaction mixture). A total of 16 experimental runs, including a 23-plan, two replicates at the central point and six star points, were carried out. Low temperatures were found to be favourable for the hydrolysis of xylan and of the easily hydrolyzable glucan fraction. High glucose formation (up to 15.3 g/100 g), attributable to starch hydrolysis, was detected in the hydrolysates obtained under the least severe pre-treatment conditions. Using the experimental results, several models for predicting the effect of the operational conditions on the yield of pretreated solids, xylan and glucan conversion upon pre-treatment, and on enzymatic convertibility of cellulose were developed. Optimum results were predicted for the conversion of easily-hydrolyzable glucan in the material pretreated at 140.7 C, and for the enzymatic saccharification of cellulose in the material pretreated at 169 C. These results suggested the use of two-step acid hydrolysis as future pre-treatment strategy for artisan rice hulls. Key words: Dilute acid hydrolysis, enzymatic hydrolysis, pre-treatment, rice hulls. (author)

    Female DBA mice were subjected to one of four treatments: ethanol-containing or control diets, nicotine (0.2, 1.0, 5.0 mg/kg/hr) infusion or saline infusion. After removal from the liquid diets or cessation of infusion, the animals were challenged with an acute dose of ethanol or nicotine. Chronic ethanol-fed mice were tolerant to the effects of ethanol on body temperature and open field activity and were cross tolerant to the effects of nicotine on body temperature and heart rate. Nicotine infused animals were tolerant to the effects of nicotine on body temperature and rotarod performance and were cross tolerant to the effects of ethanol on body temperature. Ethanol-induced sleep time was decreased in chronic ethanol- but not chronic nicotine-treated mice. Chronic drug treatment did not alter the elimination rate of either drug. Chronic ethanol treatment did not alter the number or affinity of brain nicotinic receptors whereas chronic nicotine treatment elicited an increase in the number of [3H]-nicotine binding sites. Tolerance and cross tolerance between ethanol and nicotine is discussed in terms of potential effects on desensitization of brain nicotinic receptors.

    The aim of this study was to determine clinical performance of gestrinone combined with ultrasound-guided aspiration and ethanol injection in treating chocolate cyst of ovary. Sixty-eight patients enrolled in this study were randomly divided into two groups: control group and combination treatment group. In the control group, 34 patients were treated with ultrasound-guided aspiration and ethanol injection. In the combination treatment group, 34 patients received gestrinone p.o. following ultrasound-guided aspiration and ethanol injection. The recurrence rate of chocolate cyst was 10-fold lower in the combination treatment group (2.94%, 1/34) than in the control group (29.4%, 10/34) at 12 months. The effective rate for reduction of chocolate cyst was significantly higher in the combination treatment group (94.12%, 32/34) than in the control group (64.71%, 22/34) (P = 0.009). Gestrinone combined with ultrasound-guided aspiration and ethanol injection therapy is an effective treatment for ovarian chocolate cyst with low recurrence rate. © 2014 The Authors.

    To report our experience with the use of benzodiazepines and haloperidol for sedation of pediatric patients with acute methamphetamine poisoning. We performed a retrospective chart review of 18 pediatric patients who were admitted to an intensive care unit for methamphetamine toxicity from January 1997 to October 2004 and treated with benzodiazepines or haloperidol. Clinical features, dose of drug received, and laboratory test results were noted. Adverse effects from the use of haloperidol such as prolonged QTc, dystonic reactions, and torsades de pointes were recorded. Eighteen patients received a benzodiazepine, the dose of which varied depending on the agent used. Twelve patients also received parenteral haloperidol. No complications developed from the use of either haloperidol or benzodiazepines. In this case series of pediatric patients poisoned with methamphetamine, parenteral benzodiazepines and haloperidol were used to control agitation. No serious adverse effects were observed from the use of these agents.

    Knowing how commonly used drugs affect performance monitoring is of great importance, because drug use is often associated with compromised behavioral control. Two of the most commonly used recreational drugs in the western world, 3,4-methylenedioxymethamphetamine (MDMA or "ecstasy") and ethanol (alcohol), are also often used in combination. The error-related negativity (ERN), correct-related negativity (CRN), and N2 are electrophysiological indices of performance monitoring. The present study aimed to investigate how ethanol, MDMA, and their co-administration affect performance monitoring as indexed by the electrophysiological correlates. Behavioral and EEG data were obtained from 14 healthy volunteers during execution of a speeded choice-reaction-time task after administration of ethanol, MDMA, and combined ethanol and MDMA, in a double-blind, placebo-controlled, randomized crossover design. Ethanol significantly reduced ERN amplitudes, while administration of MDMA did not affect the ERN. Co-administration of MDMA and ethanol did not further impair nor ameliorate the effect of ethanol alone. No drug effects on CRN nor N2 were observed. A decreased ERN following ethanol administration is in line with previous work and offers further support for the impairing effects of alcohol intoxication on performance monitoring. This impairment may underlie maladaptive behavior in people who are under influence. Moreover, these data demonstrate for the first time that MDMA does not affect performance monitoring nor does it interact with ethanol in this process. These findings corroborate the notion that MDMA leaves central executive functions relatively unaffected.

    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.

  19. Lithium-mediated protection against ethanol neurotoxicity

    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.

    AIM: To investigate an appropriate strategy for the treatment of patients with acute sigmoid volvulus in the emergency setting. METHODS: A retrospective review of 28 patients with acute sigmoid volvulus treated in the Department of Colorectal Surgery, Changhai Hospital, Shanghai from January 2001 to July 2012 was performed. Following the diagnosis of acute sigmoid volvulus, an initial colonoscopic approach was adopted if there was no evidence of diffuse peritonitis. RESULTS: Of the 28 patients with acute sigmoid volvulus, 19 (67.9%) were male and 9 (32.1%) were female. Their mean age was 63.1 ± 22.9 years (range, 21-93 years). Six (21.4%) patients had a history of abdominal surgery, and 17 (60.7%) patients had a history of constipation. Abdominal radiography or computed tomography was performed in all patients. Colonoscopic detorsion was performed in all 28 patients with a success rate of 92.8% (26/28). Emergency surgery was required in the other two patients. Of the 26 successfully treated patients, seven (26.9%) had recurrent volvulus. CONCLUSION: Colonoscopy is the primary emergency treatment of choice in uncomplicated acute sigmoid volvulus. Emergency surgery is only for patients in whom nonoperative treatment is unsuccessful, or in those with peritonitis. PMID:23946604

    Full Text Available Background/Aim. Antibiotics choice and the duration of their application in the therapy of acute odontogenic abscess is considered to be controversial. The aim of this study was to investigate the clinical efficacy of ampicillin in treatment of acute odontogenic abscess and to assess the antimicrobial susceptibility of the isolated bacteria in early phase of abscess development. Methods. This study included 60 patients with acute odontogenic abscess who were surgically treated (extraction of teeth and/or abscess incision divided into two groups, ampicillin group and surgical group (without antibiotic treatment. Results. In the ampicillin group of patients treatment lasted on the average 4.67 days, while in the surgical group 6.17 days. A total of 78 bacterial strains were isolated from 60 patients. The most often bacteria were found to be Gram-positive facultative anaerobs (68/78. The most common bacteria isolated were Viridans streptococci (43/78. Susceptibility of isolated bacteria to ampicillin were 70.5%. Conclusion. Peroral use of ampicillin, after surgical treatment in an early phase of dentoalveolar abscess development, statistically significantly reduced the time of clinical symptoms of acute odontogenic abscess in comparison to surgical treatment only. The isolated bacterial strains in an early phase of dentoalveolar abscess development showed a high sensitivity to ampicillin.

    Full Text Available Objective: To observe the clinical effect of nasointestinal feeding tube for enteral nutrition in the treatment of acute pancreatitis. Methods: A total of 128 patients with acute pancreatitis who were admitted in our hospital were included in the study and randomized into the treatment group and the control group with 64 cases in each group. Routine pancreatitis treatments after admission in the two groups were performed. On the basis, nasointestinal feeding tube was indwelled in patients in the treatment group for nutrition support. The changes of biochemical and nutritional indicators before and after treatment in the two groups were compared. Results: LC, TP, ALB, and Hb after treatment in the two groups were significantly elevated, while AMY and Lipase were significantly reduced when compared with before treatment (P0.05. Conclusions: Adoption of nasointestinal feeding tube for enteral nutrition in the treatment of acute pancreatitis can significantly improve the nutritional status; therefore, it deserves to be widely recommended in the clinic.

    Gene expression studies identified the interleukin-1 receptor type I (IL-1R1) as part of a pathway associated with a genetic predisposition to high alcohol consumption, and lack of the endogenous IL-1 receptor antagonist (IL-1ra) strongly reduced ethanol intake in mice. Here, we compared ethanol-mediated behaviors in mice lacking Il1rn or Il1r1. Deletion of Il1rn (the gene encoding IL-1ra) increases sensitivity to the sedative/hypnotic effects of ethanol and flurazepam and reduces severity of acute ethanol withdrawal. Conversely, deletion of Il1r1 (the gene encoding the IL-1 receptor type I, IL-1R1) reduces sensitivity to the sedative effects of ethanol and flurazepam and increases the severity of acute ethanol withdrawal. The sedative effects of ketamine and pentobarbital were not altered in the knockout (KO) strains. Ethanol intake and preference were not changed in mice lacking Il1r1 in three different tests of ethanol consumption. Recovery from ethanol-induced motor incoordination was only altered in female mice lacking Il1r1. Mice lacking Il1rn (but not Il1r1) showed increased ethanol clearance and decreased ethanol-induced conditioned taste aversion. The increased ethanol- and flurazepam-induced sedation in Il1rn KO mice was decreased by administration of IL-1ra (Kineret), and pre-treatment with Kineret also restored the severity of acute ethanol withdrawal. Ethanol-induced sedation and withdrawal severity were changed in opposite directions in the null mutants, indicating that these responses are likely regulated by IL-1R1 signaling, whereas ethanol intake and preference do not appear to be solely regulated by this pathway.

    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.)

    Organic municipal solid waste enriched with wheat straw was subjected to wet-oxidation as a pre-treatment for subsequent enzymatic conversion and fermentation into bio-ethanol. The effect of tempera (185-195degrees C), oxygen pressure (3-12) and sodium carbonate (0-2 g l(-1)) addition on enzymatic...... in the treated waste could be converted into respectively hexose and pentose sugars compared to 46% for cellulose and 36% for hemicellulose in the raw waste. For all wet oxidation conditions tested, total carbohydrate recoveries were high (> 89%) and 44-66% of the original lignin could be converted into non......-toxic carboxylic acids mainly (2.2-4.5 % on DS basis). Simultaneous saccharification and fermentation (SSF) of the treated waste at 10% DS by Saccharomyces cerevisae yielded average ethanol concentrations of 16.5 to 22 g l(-1) for enzyme loadings of 5 and 25 FPU g(-1) DS, respectively.

    The effect of combined heat treatment and acid hydrolysis (various concentrations) on cassava grate waste (CGW) biomass for ethanol production was investigated. At high concentrations of H{sub 2}SO{sub 4} (1--5 M), hydrolysis of the CGW biomass was achieved but with excessive charring or dehydration reaction. At lower acid concentrations, hydrolysis of CGW biomass was also achieved with 0.3--0.5 M H{sub 2}SO{sub 4}, while partial hydrolysis was obtained below 0.3 M H{sub 2}SO{sub 4} (the lowest acid concentration that hydrolyzed CGW biomass) at 120 C and 1 atm pressure for 30 min. A 60% process efficiency was achieved with 0.3 M H{sub 2}SO{sub 4} in hydrolyzing the cellulose and lignin materials present in the CGW biomass. High acid concentration is therefore not required for CGW biomass hydrolysis. The low acid concentration required for CGW biomass hydrolysis, as well as the minimal cost required for detoxification of CGW biomass because of low hydrogen cyanide content of CGW biomass would seem to make this process very economical. From three liters of the CGW biomass hydrolysate obtained from hydrolysis with 0.3M H{sub 2}SO{sub 4}, ethanol yield was 3.5 (v/v%) after yeast fermentation. However, although the process resulted in gainful utilization of CGW biomass, additional costs would be required to effectively dispose new by-products generated from CGW biomass processing.

    Malignant stroke is an intracranial herniation syndrome caused by cerebral oedema after a large hemispheric or cerebellar stroke. Malignant middle cerebral artery infarction is a devastating disease with a mortality around 80% despite intensive medical treatment. Decompressive craniectomy reduces mortality and improves functional outcome - especially in younger patients (age ≤ 60 years). Decompression of the posterior fossa is a life-saving procedure in patients with malignant cerebellar infarctions and often leads to good neurological outcome.

    The possible ways of treating renal artery embolisms are reviewed with an examination of their advantages and defects. Surgical treatment has a fairly high mortality rate but quickly cures any type of vascular occlusion and will cures any type of vascular occlusion and will cure any concomitant problems such as arterial stenosis. Medical treatement with anticoagulant or mortality rate and is effective even on narrow blood vessels but the response varies according to the type of thromboembolic damage and the way the drugs are administred. Recently developed forms of radiological treatment are also examined. A personal technique successfully applied to an embolism in a patient with only one functioning kidney is described. It consists of a two-stepmechanical and pharmacological attack. First the occluded artery was opened by means of a balloon catheter that was pushedbeyond the embolism and withdrawn into the aorta after inflation of the balloon. Thrombolytic drugs (Urokinase) were then infused through the catheter into the bed of the renal artery in order to cure the secondary thrombosis found, as is generally the case, downstream of the embolism. The technique appears ideal for the treatment of patients with embolisms and total involvement of the renal parenchyma, especially when their general condition makes surgery inadvisable

    Debate continues on the merits of strictly limiting alcohol consumption during all of pregnancy, and whether "safe" consumption levels and/or times exist. Only a relatively few experimental studies have been conducted that limit the timing of exposure to specific events during development and the exposure level to one that might model sporadic, incidental drinking during pregnancy. In the present study, the effects of two acute gavage exposures to low and moderate levels of ethanol (peak blood ethanol concentrations (BEC) of 104 and 177mg/dl, respectively) either during gastrulation on gestational day (GD) 7 (at GD7:0h and GD7:4h) or during neurulation on GD8 (at GD8:6h and GD8:10h) on the spatial learning and memory abilities of adult mice in the radial arm maze (RAM) were examined. Mice were selected from a prenatal ethanol exposure (PAE) cohort that had been tested as neonates for their sensorimotor development (Schambra et al., 2015) and as juveniles and young adults for open field activity levels and emotionality (Schambra et al., 2016). Mice exposed on either of the two gestational days to acute, low or moderate levels of ethanol were deficient in overall performance in the RAM in adulthood. Importantly, mice in ethanol exposed groups took longer to reach criterion in the RAM, and many mice in these groups failed to do so after 48 trials when testing was terminated. Exposure to a low level of ethanol on either GD7 or GD8, or a moderate level on GD7, resulted in significant impairment in spatial reference (long-term) memory, while only mice exposed on GD7 to the low level of ethanol were significantly impaired in spatial working (short-term) memory. Mice exposed to the low ethanol level on either day had significantly shorter response latencies, which may reflect impairment of processes related to response inhibition or executive attention in these mice. For all measures, distributions of individual scores revealed a relatively small subset of mice in each PAE

    Schinus molle var. areira L. (Anacardiaceae) is employed in herbal medicine for many conditions, including respiratory, urinary and menstrual disorders, and as a digestive stimulant, diuretic, astringent and antidepressant. It is also known for its topical use as wound healer, antiseptic, for skin disorders and as repellent and insecticide. In the present work, the acute dermal exposure to ethanolic and hexanic extracts from leaves of Schinus molle var. areira was studied in rats. A single dose of 2000 mg/kg of body weight of ethanolic and hexanic extracts from leaves was applied on the shaved skin of male and female rats. After 24h of exposure, the patch was removed and any sign of irritation was recorded. Behavioral and functional parameters in a functional observational battery and motor activity in an open field were assessed after the exposure to the extracts. Then, after 14 days of observation, animals were retested. Finally, histopathological studies were conducted on several organs. Slight signs of erythema and edema were observed in the skin site of exposure, but they disappeared after 48 h. The exposure to the hexanic extract produced an increase in parameters of activity, rearing and arousal assessed in the functional observational battery, which reversed after 14 days. On the other hand, the ethanolic extract caused an increase in locomotor activity, reflected in a higher number of rearings performed in the open field in the evaluation carried out on Day 14. No histopathological alterations were detected in the analyzed organs. The results show that the acute dermal exposure of the ethanolic and hexanic extracts from leaves of Schinus molle var. areira only causes a slight and reversible skin irritation, and a mild stimulatory effect in rats. All these indicate that the topical use of these extracts would be safe. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    To evaluate the long-term follow-up results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in Korea. Sixty-eight nodular HCCs initially detected in 64 patients, were subjected to US-guided PEI as a first-line treatment. Long-term survival rates, local tumor progression rates, and complications were evaluated, as were the influences of tumor size and Child-Pugh class on these variables. No major complications occurred. The overall survival rates of the 64 patients at three and five years were 71% and 39%, and their cancer-free survival rates were 22% and 15%, respectively. The overall survival rate of patients with a small HCC (≤ 2 cm) was significantly higher (p = 0.014) than that of patients with a medium-sized HCC (≤ 2 cm). The overall survival rate of patients with Child- Pugh class A was significantly higher (p = 0.049) than that of patients with Child- Pugh class B. Of 59 cases with no residual tumor, local tumor progression was observed in ablation zones in 18, and this was not found to be significantly influenced by tumor size or Child-Pugh class. The results of our investigation of the long-term survival rates of PEI in HCC patients in Korea (a hepatitis B virus-endemic area) were consistent with those reported previously in hepatitis C endemic areas. Patients with a smaller tumor or a better liver function exhibited superior survival rates

    Full Text Available Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL; postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes; no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1, 41–60 (n=1, and >60 (n=55; scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

    Objectives: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyper functioning adrenal disorders. Method: We retrospectively evaluated the long-term results of nine patients treated with computed tomography guided percutaneous ethanol ablation: eight subjects who presented with primary adrenal disorders, such as pheochromocytoma, primary macro nodular adrenal hyperplasia and aldosterone-producing adenoma, and one subject with Cushing disease refractory to conventional treatment. Eleven sessions were performed for the nine patients. The patient data were reviewed for the clinical outcome and procedure-related complications over ten years. Results: Patients with aldosterone-producing adenoma had clinical improvement: symptoms recurred in one case 96 months after ethanol ablation, and the other patient was still in remission 110 months later. All patients with pheochromocytoma had clinical improvement but were eventually submitted to surgery for complete remission. No significant clinical improvement was seen in patients with hypercortisolism due to primary macro nodular adrenal hyperplasia or Cushing disease. Major complications were seen in five of the eleven procedures and included cardiovascular instability and myocardial infarction. Minor complications attributed to sedation were seen in two patients. Conclusion: Computed tomography-guided ethanol ablation does not appear to be suitable for the long-term treatment of hyper functioning adrenal disorders and is not without risks. (author)

    Some small hepatocellular carcinoma (HCC) lesions show as tumor stains by dynamic CT, but cannot be detected by ultrasonography. Percutaneous ethanol injection (PEI) is effective for treating small HCC lesions, but lack of adequate visualization of some lesions can limit its use. In this study, interventional radiographic, CT-fluoroscopically-guided PEI was performed as a new method for treating small HCC lesions that were difficult to detect by ultrasonography. Interventional radiographic, CT-fluoroscopically-guided PEI was performed on 11 patients (12 lesions) with HCC lesions measuring 2 cm or less in diameter. A thin needle was introduced into each tumor under CT-fluoroscopic guidance, with injection of contrast medium into the dominant hepatic artery. While lesions were observed using CT-fluoroscopy with the arteriogram, absolute ethanol was injected into the tumors. The ethanol injection rate and volume were monitored by observation of loss of tumor staining during real-time CT angiography. Needle introduction was successful in all 12 lesions, and disappearance of tumor staining was immediately observed on CT images after ethanol injection. Complications noted after treatment were local abdominal pain in all 11 patients, a slight fever in 9 patients, pneumothorax, right pleural effusion, and ascites, each in 1 patient. No other serious complications were observed. Interventional radiographic, CT-fluoroscopically-guided PEI is effective in the treatment of small HCC lesions, which are difficult to show by ultrasonography and treat by conventional PEI. (author)

    Full Text Available Background Different methods of surgical treatment for acromioclavicular(ACjoint injury were considered in the literature. The purpose of the study was to compare intra- articular AC repair technique with the extra-articular coracoclavicular repair technique for the patients with Rockwood type III and VAC joint injury when indicated.Methods: Nineteen consecutive patients with Rockwood type III and VAC joint injury  were treated with intra-articular (Group I - 12 cases and extra-articular (Group II - 7cases repair technique between 1380 - 1386, and the results reviewed. When the diagnosis was established, the mean age of the patients was 32.5 years (Range, 18 - 60; group I and II 31.8 years (Range, 18 - 60 and 34 years (Range, 22 - 58 respectively. The mean duration of postoperative follow - up was 24 months. The Constant shoulder scoring system was applied to obtain clinical results.   Results: Only in group I, the post-surgical complication was associated with fiber allergy, wound infection and pin site infection in two patients respectively. No pain was detected in fourteen cases. Four patients in group I had occasional mild pain during sport activity, while one case in this group reported severe pain during resting which prevented the patient from activity. Also, there was an ossification in thirteen patients particularly in group I. Clinical results showed the mean constant shoulder score was 93.4 in group I and 97.1 in group II.Conclusion: At the time of the follow - up, there was a clear difference between both groups regarding to postoperative pain and discomfort.Therefore, it seemed that potential cause of pain was due to postoperative complications. An interesting postoperative complication without interfere in the functional outcome was coracoclavicular space ossification in most cases. This was probably because of soft tissue injury during the operation.It seemed that surgical treatment of Rockwood type III and VAC joint injuries

    To establish the role of percutaneous ethanol injection (PEI) treatment in benign thyroid lesions by evaluating: (1) the long-term efficacy and side effects of the treatment, (2) the factors predictive of efficacy of PEI, and (3) the cost effectiveness of the procedure. Fifty-eight recurrent cystic nodules, 95 autonomously functioning nodules (AFTN), and 17 hyperfunctioning nodules causing thyrotoxicosis (toxic nodules) were treated by PEI from 1990 to 1996 in our center. Ultrasound (US) and color flow doppler (CFD) examinations were carried out before and after each treatment. In patients with AFTN, serum thyrotropin (TSH), free triiodothyronine (FT3), free thyroxine (FT4), thyroid peroxidase antibody (TPOAb) levels were tested before and after PEI. All patients were independently reexamined by two external reviewers after a minimum follow-up of 5 years (median, 6.9 years). The median number of treatments was 2.0 (range, 1.0-4.0) for cystic nodules, 4 (range, 2.0-6.0) for AFTN, and 5 (range, 3.0-7.0) for toxic nodules. At the 5-year evaluation cystic nodules showed a volume reduction greater than 75% versus baseline in 86.2% of cases and an improvement of local symptoms in 91.4% of cases. AFTN presented serum TSH within normal limits in 60.0% of patients. Toxic nodules showed a detectable serum TSH and normal FT3 and FT4 values in 35.3% of cases. Two cases of transient dysphonia were observed. In cystic lesions no significant correlation was found between the baseline and the final volume (r2 = 0.17) and no significant predictor of treatment efficacy was found. However, unilocularity was associated with a lower number of treatments than multilocularity (median, 2.0 vs. 3.0). Independent predictors of clinical efficacy in both AFTN and toxic nodules were a baseline volume less than 5.0 mL and a fluid component greater than 30% (odds ratio [OR] = 6.1 and 3.3, respectively). Most recurrent cystic lesions of the thyroid can be cured by PEI, which should become the

  7. The acute and preventative treatment of episodic migraine

    Directory of Open Access Journals (Sweden)

    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.

    2016-03-01

    The proportion of diabetic patients who are hospitalised for stroke has been increasing in recent years, currently reaching almost a third of all cases of stroke. In addition, about half of patients with acute stroke present hyperglycaemia in the first hours of the stroke. Although hyperglycaemia in the acute phase of stroke is associated with a poor prognosis, its treatment is currently a topic of debate. There is no evidence that the adminstration of intravenous insulin to these patients offers benefits in terms of the evolution of the stroke. New studies in development, such as the SHINE study (Stroke Hyperglycemia Insulin Network Effort), may contribute to clarifying the role of intensive control of glycaemia during the acute phase of the stroke. Ultimately, patients who have presented with stroke should be screened for diabetes. Copyright © 2015 Elsevier España, S.L.U. y Sociedad Española de Medicina Interna (SEMI). All rights reserved.

    Objective: To occumulatle experience of anti-infection treatment in acute radiation sickness (ARS) induced by medical treatment in order to provide beneficial help for victims of accidental of acute radiation sickness. Methods: The changes of peripheral blood indices, body temperature and clinical symptoms of 17 cases who were clinically irradiated with 6.0-7.2 Gy X-rays were observed both before peripheral blood stem cell transplantation(PBSCT) and after anti-infection treatment. Results: WBC count began to decrease to below 1 x 10 9 /L from the 8th to 10th days after irradiation and maintained at row level for 4 days or for 13.3 days if the patients had not received rhG-CSF treatment. In 29.4% of patients the body temperature was higher than 38.5 degree C. After comprehensive enviromental protection and anti-infection treatment, all patients could successfully tide over the period of bone marrow depression without appearance of the typical critical phase of ARS. Conclusion: PBSCT and rhG-CSF treatment can reduce the time span for reconstruction of bone marrow. Comprehensive enviromental protection and combined anti-infection treatment are key points fm successful treatment. (authors)

    Clinical case reports and prospective trials have demonstrated a reproducible benefit of hypothalamic-pituitary-adrenal (HPA) axis modulation on the rate of recovery from acute inflammatory central nervous system (CNS) demyelination. As a result, corticosteroid preparations and adrenocorticotrophic hormones are the current mainstays of therapy for the treatment of acute optic neuritis (AON) and acute demyelination in multiple sclerosis.Despite facilitating the pace of recovery, HPA axis modulation and corticosteroids have failed to demonstrate long-term benefit on functional recovery. After AON, patients frequently report visual problems, motion perception difficulties and abnormal depth perception despite 'normal' (20/20) vision. In light of this disparity, the efficacy of these and other therapies for acute demyelination require re-evaluation using modern, high-precision paraclinical tools capable of monitoring tissue injury.In no arena is this more amenable than AON, where a new array of tools in retinal imaging and electrophysiology has advanced our ability to measure the anatomic and functional consequences of optic nerve injury. As a result, AON provides a unique clinical model for evaluating the treatment response of the derivative elements of acute inflammatory CNS injury: demyelination, axonal injury and neuronal degeneration.In this article, we examine current thinking on the mechanisms of immune injury in AON, discuss novel technologies for the assessment of optic nerve structure and function, and assess current and future treatment modalities. The primary aim is to develop a framework for rigorously evaluating interventions in AON and to assess their ability to preserve tissue architecture, re-establish normal physiology and restore optimal neurological function.

    Lithium continues to be the treatment of choice for bipolar disorder. Acute lithium poisoning is a potentially serious event. We present a retrospective observational significative study of episodes of acute lithium poisoning during a 52- month period. Poisoning was defined by a blood lithium concentration of 1.5 mEq/L or higher. We analyzed treatment and epidemiologic and clinical characteristics of 70 episodes were identified (incidence density among treated patients, 1.76 per 100 patient-years). The most frequent cause of lithium poisoning was a concurrent medical condition (46%). Most poisonings were mild (74.2%), but neurologic involvement was identified in 40.3%. Electrocardiographic abnormalities were found in 8 cases. Acute renal failure, found in 23 patients (37.1%), was mild in most cases, although 11 patients required hemodialysis. We concluded that acute lithium poisoning is an uncommon complication, but risk needs to be lowered. Patients should be warned to avoid dosage errors and to take special care during concurrent illnesses and while taking other medications.

    The aim of the study was to determine whether an oral treatment with a commercial pharmaceutical product containing Saccharomyces boulardii would reduce the duration of diarrhea in infants with acute diarrhea. In the present double-blind, placebo-controlled study, 186 infants, 6 to 48 months old and hospitalized within 72 hours after the onset of acute diarrhea in 2 hospitals in Goiânia, Goiás, Brazil, were randomly assigned to receive twice per day for 5 days 200 mg of a commercial pharmaceutical product containing 4 × 10 viable cells of S boulardii or a placebo. Stool samples were submitted to search for rotavirus. Among the 176 infants who completed the trial, those treated with S boulardii (90) showed a reduction in diarrhea duration (P boulardii was given to children within 72 hours after the onset of acute diarrhea. The present study suggests a complementary treatment of acute diarrhea in infants with daily oral doses of S boulardii.

    Full Text Available Transnasal sphenopalatine ganglion block is emerging as is an attractive and effective treatment modality for acute migraine headaches, cluster headache, trigeminal neuralgia, and several other conditions. We assessed the efficacy and safety of this treatment using the Sphenocath® device. 55 patients with acute migraine headaches underwent this procedure, receiving 2 ml of 2% lidocaine in each nostril. Pain numeric rating scale (baseline, 15 minutes, 2 hours, and 24 hours and patient global impression of change (2 hours and 24 hours after treatment were recorded. The majority of patients became headache-free at 15 minutes, 2 hours, and 24 hours after procedure (70.9%, 78.2%, and 70.4%, resp.. The rate of headache relief (50% or more reduction in headache intensity was 27.3% at 15 minutes, 20% at 2 hours, and 22.2% at 24 hours. The mean pain numeric rating scale decreased significantly at 15 minutes, 2 hours, and 24 hours, respectively. Most patients rated the results as very good or good. The procedure was well-tolerated with few adverse events. This treatment is emerging as an effective and safe option for management of acute migraine attacks.

    Although the rise in health costs is a widely debated issue, in Switzerland it was until recently taken for granted that patients are given the best available treatment regardless of cost. An example of a disease requiring costly treatment is acute myelogenous leukaemia (AML). To relate cost to benefit we calculated expenditure per life years gained. To assess costs we determined the real cost of treatment up to total remission, followed by consolidation or withdrawal of treatment or death. For survival time exceeding the 2-year observation period we used data from recent literature. The average cost of treatment ranges up to 107,592 Swiss francs (CHF). In 1997 we treated 23 leukaemia patients at Zurich University Hospital and gained a total of 210 life years. This represents an average cost of CHF 11,741 per life year gained. Chief cost items were therapy and personnel costs for nursing staff, followed by hotel business and personnel costs for doctors and diagnosis. Our results for AML treatment are far removed from the $61,500 ranging up to $166,000 discussed in the literature as the "critical" QALY (quality adjusted life years) value. This is the first time the actual costs of AML therapy have been shown for a Swiss cohort. Despite high initial treatment costs and success only in a limited number of patients, the expenditure per QALY is surprisingly low and shows clearly the effectiveness of apparently costly acute medicine.

    A classification system in German language is proposed for scoring of acute and chronic treatment sequelae after radiotherapy. It includes all important organs and organ systems. The proposed grading corresponds to the four-scale-system of the WHO and UICC. The system is also compatible to the RTOG and EORTC acute and late radiation morbidity scoring criteria. This facilitates the data transfer for retrospective and prospective analysis of monomodal and multimodal radiotherapy treatment regimes. We recommend to use this scoring system in all German speaking countries for multicentric prospective studies. It is possible, that organ-specific sophistications of the toxicity grading will be developed in the future. These additions should conform with (inter)national standards and apply the same four-scale grading of this classification system. (orig.) [de

  1. Patient Satisfaction in the Treatment of Acute Hamstring Strain Injury

    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

    Percutaneous ethanol injection (PEI) is an alternative therapy for thyroid nodules (TN). However, some concern is raised on its carcinogenic effects. To evaluate the cytological and clinical changes caused by PEI in patients with benign TN. Thirty-nine patients with TN (23.1% hyperfunctioning) were submitted to a median of three PEI sessions. After a median of 17 months, patients were reassessed. A new ultrasound-guided fine needle biopsy (US-FNB) was performed, and the smears were analyzed after May-Grünwald-Giemsa staining. The diagnostic findings and the cellular characteristics were compared before and after treatment. There was an increase in the proportion of nondiagnostic/unsatisfactory results (from 2.5% to 18.9%). No malignant cases were observed. The proportion of moderate/intense macrophage infiltration decreased from 60% to 15%. Before treatment, 23.1% patients had hyperthyroidism, which was completely or partially resolved in 66.7%. By ultrasound, the percentage of homogeneous nodules decreased from 64.0% to 38.4% (p=0.0235), and the mean nodule volume decreased from 13.4 ± 12.2 to 5.3 ± 5.1 cm(3). We demonstrate that PEI increases the proportion of nondiagnostic/unsatisfactory results from US-FNB. Therefore, cytological findings after PEI must be evaluated with caution. Our results also suggest that PEI is an efficacious and safe therapeutic option, with no carcinogenic effects observed on cytological evaluations. Safety and efficacy must be evaluated in larger studies with longer follow-up periods.

    1 The effects of single doses (25 g and 50 g) oral ethanol on the disposition of acetanilide (50 mg/kg metabolic active mass) has been studied in normal subjects, and in patients with chronic non-alcoholic liver disease. 2 In normal subjects, ethanol produced a dose-dependent increase in acetanilide half-life, and a decrease in acetenilide clearance. There was a significant correlation (rs = 0.71, P less than 0.01) between the 90 min blood ethanol concentration and the reduction in acetanilide clearance. 3 In patients with liver disease, ethanol produced a similar proportional change in acetanilide half-life and clearance, but these were less consistent. Moreover, liver disease itself was associated with an increase in acetenilide half-life, and a reduction in clearance. 4 It is concluded that single oral doses of ethanol, comparable to those consumed during social drinking, may inhibit some forms of microsomal oxidation and thus have important clinical implications.

    Full Text Available Background Axillary osmidrosis is characterized by unpleasant odors originating from the axillary apocrine glands, resulting in psychosocial stress. The main treatment modality is apocrine gland removal. Until now, of the various surgical techniques have sometimes caused serious complications. We describe herein the favorable outcomes of a new method for ablating apocrine glands by minimal subdermal shaving using sclerotherapy with absolute ethanol.Methods A total of 12 patients underwent the procedure. The severity of osmidrosis was evaluated before surgery. Conventional subdermal shaving was performed on one side (control group and ablation by means of minimal subdermal shaving and absolute ethanol on the other side (study group. Postoperative outcomes were compared between the study and control groups.Results The length of time to removal of the drain was 1 day shorter in the study group than in the control group. There were no serious complications, such as hematoma or seroma, in either group, but flap margin necrosis and flap desquamation occurred in the control group, and were successfully managed with conservative treatment. Six months after surgery, we and our patients were satisfied with the outcomes.Conclusions Sclerotherapy using absolute ethanol combined with minimal subdermal shaving may be useful for the treatment of axillary osmidrosis. It can reduce the incidence of seroma and hematoma and allow the skin flap to adhere to its recipient site. It can degrade and ablate the remaining apocrine glands and eliminate causative organisms. Furthermore, since this technique is relatively simple, it takes less time than the conventional method.

    Sequelae of the treatment of children with acute lymphocytic leukemia (ALL) include multiple effects on the endocrine system, especially as it relates to growth and puberty. Thyroid dysfunction, and in particular, the occurrence of thyroid neoplasia, has been only rarely described. We report the development of benign thyroid neoplasms in two patients 9 years following the diagnosis and treatment of ALL. Both patients were clinically and biochemically euthyroid with noncystic cold nodules found on thyroid scan. In light of these observations, and along with previous reports of malignant thyroid neoplasia in children with ALL, long-term careful observation of children successfully treated for ALL is indicated. 17 references

    The presence of the Philadelphia chromosome is a poor prognosis factor in acute lymphoblastic leukemia (ALL), in both children and adults. Using molecular techniques of the gen bcr/abl, it is possible to detect the abnormality, in up to the 40% of adult patients. The unsatisfactory results with conventional chemotherapy schemes have determined the intensification of the treatments and the consideration of allogenic bone marrow transplants as the best therapeutic instance. The development of tyrosine kinase inhibitors have become a therapeutic improvement in the treatment of Philadelphia chromosome-positive ALL, being combined with chemotherapy schemes, only in a selected group of patients, even in therapeutic programs that include transplant.

    Procedures for the clinical assessment of acute poisoning by substances of abuse should identify patients in need of hospital admission and avoid hazardous discharges, while keeping the observation time short. We assess the safety of a systematic procedure developed at the Oslo Accident and Emergency Outpatient Clinic (OAEOC). All patients 12 years and older treated for acute poisoning by substances of abuse at the OAEOC were included consecutively from October 2011 to September 2012. Data were collected on pre-set registration forms. Information on re-presentations to health services nation-wide during the first week following discharge was retrieved from the Norwegian Patient Register and from local electronic medical records. Information on fatalities was obtained from the Norwegian Cause of Death Registry. There were 2343 cases of acute poisoning by substances of abuse. The main toxic agent was ethanol in 1291 (55 %) cases, opioids in 539 (23 %), benzodiazepines in 194 (8 %), central stimulants in 132 (6 %), and gamma-hydroxybutyrate (GHB) in 105 (4 %). Median observation time was four hours. The patient was hospitalised in 391 (17 %) cases. Two patients died during the first week following discharge, both from a new opioid poisoning. Among 1952 discharges, 375 (19 %) patients re-presented at the OAEOC or a hospital within a week; 13 (0.7 %) with a diagnosis missed at the index episode, 169 (9 %) with a new poisoning, 31 (2 %) for follow-up of concomitant conditions diagnosed at index, and 162 (8 %) for unrelated events. Among the patients with missed diagnoses, five needed further treatment for the same poisoning episode, two were admitted with psychosis, one had hemorrhagic gastritis, another had fractures in need of surgery and four had minor injuries. The procedure in use at the OAEOC can be considered safe and could be implemented elsewhere. The high re-presentation rate calls for better follow-up.

    Full Text Available Acute bacterial postoperative endophthalmitis (AE is a destructive intraocular infection with a tendency to an increase of morbidity and prevalence. This phenomenon is contributed by worldwide increase of surgical activity together with an increase of life expectancy. Nowadays AE prevalence in the best ophthalmic clinics of the world varies from 0.039% to 0.59%. Modern approaches to complex treatment of acute bacterial postoperative endophthalmitis are described in details in EVS 1995 and ESCRS 2013 investigations where the two main standards — “gold” and “silver” — are reflected. “Gold standard” includes 3-port vitrectomy with bacterial seeding of anterior chamber and vitreous cavity content and intravitreal antibiotics injection at the final step of operation within 1 hour after diagnosing acute endophthalmitis. Use of “silver standard” is acceptable in absence of vitreoretinal operation room and trained surgeon, that is, in case if full vitreoretinal surgery is impossible. In such cases surgical intervention is limited by taking vitreous cavity and anterior chamber content for bacterial seeding with intravitreal antibiotics injection at the final step of operation. Nowadays surgeons have the task not only to suppress infection and preserve the eye as an organ, but also to preserve maximal possible visual functions. The review deals with the questions of antibiotics choice with sufficient antibacterial spectrum and minimal toxicity. Questions of modern antibiotics pharmacokinetics and influencing factors such as molecular mass of the antibiotic, the extent of vitreous liquefaction, solubility coefficient of the antibiotic, the extent of eyeball inflammation, status of iris-lens diaphragm and vitreous cavity (phakic, aphakic, pseudophakic, avitreal eye, silicone tamponade, density of antibiotic solution are being discussed. Features and advantages of vitreal surgery are considered. Choice of vitreous body substitutes which

    In patients with acute carbon monoxide (CO) poisoning, we have noted wide clinical variability in both criteria for hyperbaric oxygen (HBO2) treatment as well as HBO2 treatment regimens. Our aim was to survey Midwest hyperbaric centers for insight into specific criteria and protocols for treating acute CO toxicity with HBO2. Hyperbaric centers were identified from the published list of the Undersea and Hyperbaric Medical Society. Ninety-three centers from nine Midwestern states were contacted via telephone. A standard script was used to minimize surveyor bias. Thirty centers that treat CO poisonings were identified. One did not participate in the study. Nineteen reported a specific level of carboxyhemoglobin (COHb) that served as an independent indication for initiation of HBO2 treatment. Four centers used the COHb level as the exclusive indication for HBO2 treatment. Ten centers relied solely on reported symptoms, while the remaining centers used a combination of symptoms plus COHb levels. There were 19 separate treatment protocols. No uniform practice for either the initiation or implementation of HBO2 therapy for CO poisoning exists among U.S. Midwest hyperbaric centers responding to a survey. We see opportunity for specific targeted educational programs as well as further study.

    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 M 2 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 M 2 generation. The results indicate that CH and methanol alone and mixed with ethanol can potentiate gamma ray-induced genetic lesions in rice seed. (author)

    Update of Acute Ischaemic Stroke Treatment Guidelines of the Spanish Neurological Society based on a critical review of the literature. Recommendations are made based on levels of evidence from published data and studies. Organized systems of care should be implemented to ensure access to the optimal management of all acute stroke patients in stroke units. Standard of care should include treatment of blood pressure (should only be treated if values are over 185/105 mmHg), treatment of hyperglycaemia over 155 mg/dl, and treatment of body temperature with antipyretic drugs if it rises above 37.5 °C. Neurological and systemic complications must be prevented and promptly treated. Decompressive hemicraniectomy should be considered in cases of malignant cerebral oedema. Intravenous thrombolysis with rtPA should be administered within 4.5 hours from symptom onset, except when there are contraindications. Intra-arterial pharmacological thrombolysis can be considered within 6 hours, and mechanical thrombectomy within 8 hours from onset, for anterior circulation strokes, while a wider window of opportunity up to 12-24 hours is feasible for posterior strokes. There is not enough evidence to recommend routine use of the so called neuroprotective drugs. Anticoagulation should be administered to patients with cerebral vein thrombosis. Rehabilitation should be started as early as possible. Treatment of acute ischaemic stroke includes management of patients in stroke units. Systemic thrombolysis should be considered within 4.5 hours from symptom onset. Intra-arterial approaches with a wider window of opportunity can be an option in certain cases. Protective and restorative therapies are being investigated. Copyright © 2011 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

    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.

    2014-06-01

    Full Text Available Herpes zoster (HZ is a disease caused by varicella zoster virus (VZV, where the initial contact leads to varicella. The low immunity of the patient might reactivate the virus and provoke symptoms of HZ, which is characterized by vesicles and blisters localized unilaterally and accompanied by pain. The greatest diagnostic problems occur in Zoster sine herpete and painless HZ. A significant complication of acute HZ infection is chronic postherpetic neuralgia (PHN, which manifests as dull and burning pain persisting for more than 3 months after the beginning of the rash. Senility, female gender, presence of prodromal pain, more severe skin lesions, dysaesthesia, and more intense acute PHN predispose to chronic PHN. Early diagnosis and treatment of HZ infection with antiviral medications prevent PHN. Use of local anesthetics is a very good choice in acute PHN treatment. Tricyclic antidepressants (amitriptyline, nortriptyline are conventional drugs which alleviate subacute PHN. Immunomodulatory drugs such as gabapentin help prevent or reduce the severity of PHN. The other therapeutic options are RFA (radiofrequency ablation, TENS (transcutaneous electrical nerve stimulation, physical methods such as magnetotherapy and laser therapy. The attenuated vaccine, used in patients over 60 years old, is expected to prevent the occurrence of PHN.

    Enteritis is one of the side effects of radiotherapy to the abdominal cavity. Radiation enteritis involves damage to mucous membranes in the acute phase and to stromal tissues in the late phase. Perforation of the intestine tends to occur in the late phase, and rarely in the acute phase. However, we describe here a case of intestinal perforation occurring in the acute phase after irradiation in a patient who received gefitinib treatment. Gefitinib, one of the epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), is widely used to treat non-small cell lung cancer (NSCLC) patients, but is simultaneously known to inhibit wound healing. We suspect that gefitinib may affect regeneration of the small intestinal mucosa injured by irradiation. A 76-year-old woman had NSCLC with metastases to the 5th lumbar, sacral, and right iliac bones. To control the pain from bone metastasis, anterior-posterior opposing portal irradiation (total 35 Gy) was started, and was completed over 22 days. On day 25 after starting radiotherapy, the patient began to take gefitinib. On day 35, she presented with acute peritonitis, and an emergency laparotomy was performed. The terminal ileum was affected by radiation enteritis and there were two pin-hole perforations. In the surgical specimen, no cancerous lesions were detected, and immunohistochemical staining of phosphorylated EGFR (pEGFR) was negative. pEGFR has an important role in mucous membrane repair after irradiation. Intestinal perforation in the acute phase of radiation enteritis may be associated with impaired mucosal repair mechanisms due to the use of an EGFR-TKI such as gefitinib, as evidenced by the absence of pEGFR.

    Mucocele of the anterior lingual salivary glands is a more common cystic lesion, especially in patients aged less than 20 years. The study is aimed to observe the effect of treatment by injection of absolute ethanol instead of surgery. Fourteen outpatients diagnosed as mucocele of the glands of Blandin-Nuhn were selected. These patients, after blood investigation, were treated by injection of absolute ethanol into a mucous cavity of lesion under superficial anesthesia with 2% lidocaine once a week and followed up from 3 months to 2 years. Mucocele of the glands of Blandin-Nuhn was extirpated in all patients after 1 to 3 injections. There were no other complications except slight distending pain occurred on the same day when the patients were treated. The recurrence was not observed during the follow-up period. In conclusion, the study suggests that injection of absolute ethanol may be an alternative means for treating mucocele of the glands of Blandin-Nuhn, because it is mininvasive, safe, effective, economic, and simply manipulated compared with surgical treatment.

    2012-10-01

    The aim of this short-term study was to compare the clinical efficacy of 2 different methods to treat acute periodontal abscesses. After patient selection, 100 cases of acute periodontal abscess were randomly divided into two groups. The experimental group was treated by supra- and subgingival scaling, while the control group was treated by incision and drainage. A clinical examination was carried out to record the following variables: subjective clinical variables including pain, edema, redness and swelling; objective clinical variables including gingival index(GI), bleeding index(BI), probing depth(PD),suppuration, lymphadenopathy and tooth mobility. The data was analyzed with SPSS 19.0 software package.

    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

    Binge drinking of high ethanol (EtOH) concentration beverages is common among young adults and can be a risk factor for exposure to sexually transmitted diseases, including HIV-1. We used a novel noninfectious HIV-1 transgenic (HIV-1Tg) rat model that mimics HIV-1 patients in terms of altered immune responses and deficits in cognitive learning and memory to investigate EtOH concentration-dependent effects on 48 alcohol-modulated genes during binge EtOH administration. HIV-1Tg and control F344 rats were administered water, 8% EtOH, or 52% EtOH by gavage (i.g.) for 3 days (2.0 g/kg/d). Two hours after final treatment, blood, liver, and spleen were collected from each animal. Serum blood EtOH concentration (BEC) was measured, and gene expression in the liver and spleen was determined using a specifically designed PCR array. The BEC was significantly higher in the 52% EtOH-treated HIV-1Tg rats compared with the 8% EtOH group; however, the BEC was higher in the 8% EtOH-treated control rats compared with the 52% EtOH group. There was no change in expression of the EtOH metabolism-related genes, Adh1, Adh4, and Cyp2e1, in either the 8 or 52% EtOH-treated HIV-1Tg rats, whereas expression of those genes was significantly higher in the liver of the 52% EtOH control rats, but not in the 8% EtOH group. In the HIV-1Tg rats, expression of the GABAA , metabotropic glutamate, and dopamine neurotransmitter receptor genes was significantly increased in the spleen of the 52% EtOH group, but not in the 8% EtOH group, whereas no change was observed in those genes in either of the control groups. Our data indicate that, in the presence of HIV-1 infection, EtOH concentration-dependent binge drinking can have significantly different molecular effects.

    We evaluated delayed neurotoxicities in treatment of childhood acute leukemia. Of 28 patients treated over 2 years who were examined on computed tomography of brain scans, 7 patients had abnormal findings. These abnormalities included two cases of leukoencephalopathy, three cases of intracranial calcifications, and two of ventricular dilatation. These patients were under 6 years old at the onset of disease, especially under 3 years old. Also, delayed neurotoxicities developed after relapse of leukemia, especially CNS relapse. It was considered that these were caused by cranial irradiation, intravenous methotrexate injection, intrathecal methotrexate, and sometimes high-dose Ara-C therapy, etc. Most of the cases of leukoencephalopathy were associated with treatment of intermediate-dose or high-dose methotrexate after relapse. These abnormalities must be carefully considered in the treatment of younger children with leukemia and patients with relapse. (author)

    Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

    An accurate diagnosis of acute appendicitis is important to avoid severe outcome or unnecessary surgery but management is controversial. The aim of study was to evaluate, in younger and older children, the efficacy of conservative management for uncomplicated appendicitis and the outcome of complicated forms underwent early surgery. Children with acute appendicitis were investigated by clinical, laboratory variables and abdominal ultrasound and divided in two groups: complicated and uncomplicated. Complicated appendicitis underwent early surgery; uncomplicated appendicitis started conservative treatment with antibiotic. If in the next 24-48h it was worsening, the conservative approach failed and patients underwent late surgery. A total of 362 pediatric patients were included. One hundred sixty-five underwent early appendectomy; 197 patients were at first treated conservatively: of these, 82 were operated within 24-48h for failure. The total percentage of operated patients was 68.2%. An elevated association was found between surgery and ultrasound. Conservative treatment for uncomplicated appendicitis had high percentage of success (58%). Complications in operated patients were infrequent. Our protocol was effective in order to decide which patients treat early surgically and which conservatively; specific red flags (age and onset) can identified patients at most risk of complications or conservative failure. treatment study.

    Full Text Available Objective: to evaluate the efficiency of combination use of hyperbaric oxygenation, succinate-containing solutions, and anti-edematous agents in patients with acute carbon monoxide poisoning. Subjects and methods. The results of treatment were analyzed in 32 patients admitted in 2009—2011 for severe acute carbon monoxide poisoning and a Glasgow coma score of 6—8. The patients were divided into 2 groups: 1 patients whose combination therapy involved hyperbaric oxygenation, Succinasol infusions, and L-lysine-aescinate injections; 2 those who received traditional therapy. All the patients underwent complex clinical, laboratory, and neurophysiologic examinations. Results. Just 24 hours after the combination use of Succinasol and L-lysine-aescinate, Group I patients were observed to have substantially reduced lactate, the content of the latter approached the normal value following 48 hours, which was much below the values in the control group. The similar pattern was observed when endogenous intoxication parameters were examined. During the performed therapy, the level of consciousness and that of intellect according to the MMSE and FAB scales were restored more rapidly in the study group patients than in Group 2. Conclusion. The combination use of hyperbaric oxygenation, the succinate-containing solution Succinasol, and the anti-edematous agent L-lysine-aescinate considerably enhances the efficiency of intensive therapy for acute carbon monoxide poisoning. Key words: carbon monoxide, toxic hypoxic encephalopathy, combination therapy, hyperbaric oxygenation, succinic acid, L-lysine-aescinate.

    The article deals with the radiation treatment of acute myelogenous leukaemia. The contribution of radiotherapy can be considered in three parts: a) irradiation of blood packs for patient support; b) irradiation of laboratory animals in order to improve existing knowledge and techniques; c) total body irradiation of the patient on the day of the transplant using a dose large enough to destroy the bone marrow and the immune system. The radiation effects, post graft immunosuppression and the supporting of the patient after transplantation are also discussed.

    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.

    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.

    Ankle injuries, especially ankle sprains, are a common problem in sports and medical care. Ankle sprains result in pain and absenteeism from work and/or sports participation, and can lead to physical restrictions such as ankle instability. Nowadays, treatment of ankle injury basically consists of taping the ankle. The purpose of this review is to evaluate the effectiveness of ankle braces as a treatment for acute ankle sprains compared with other types of functional treatments such as ankle tape and elastic bandages. A computerized literature search was conducted using PubMed, EMBASE, CINAHL and the Cochrane Clinical Trial Register. This review includes randomized controlled trials in English, German and Dutch, published between 1990 and April 2009 that compared ankle braces as a treatment for lateral ankle sprains with other functional treatments. The inclusion criteria for this systematic review were (i) individuals (sports participants as well as non-sports participants) with an acute injury of the ankle (acute ankle sprains); (ii) use of an ankle brace as primary treatment for acute ankle sprains; (iii) control interventions including any other type of functional treatment (e.g. Tubigrip™, elastic wrap or ankle tape); and (iv) one of the following reported outcome measures: re-injuries, symptoms (pain, swelling, instability), functional outcomes and/or time to resumption of sports, daily activities and/or work. Eight studies met all inclusion criteria. Differences in outcome measures, intervention types and patient characteristics precluded pooling of the results, so best evidence syntheses were conducted. A few individual studies reported positive outcomes after treatment with an ankle brace compared with other functional methods, but our best evidence syntheses only demonstrated a better treatment result in terms of functional outcome. Other studies have suggested that ankle brace treatment is a more cost-effective method, so the use of braces after acute

    We aimed to explore patients' preferences for headache treatments with a self-administered questionnaire including the Q-No questionnaire for nocebo. Questionnaires from 514 outpatients naïve to neurostimulation and monoclonal antibodies were collected. Patients assessed that the efficacy of a treatment is more important than safety or route of administration. They preferred to use an external neurostimulation device for both acute (67.1%) and preventive treatment (62.8%). Most patients preferred to take a pill (86%) than any other drug given parenterally for symptomatic pharmaceutical treatment. For preventive pharmaceutical treatment, most patients preferred to take a pill once per day (52%) compared to an injection either subcutaneously or intravenously each month (9% and 4%), or three months (15% and 11%). 56.6% of all participants scored more than 15 in Q-No questionnaire indicating potential nocebo behaviors that contributed significantly in their choices. These patient preferences along with efficacy and safety data may help physicians better choose the right treatment for the right person.

    Full Text Available Parkia platycephala Benth. (Leguminosae - Mimosoideae, popularly known as "visgueira", fava bean tree or "fava-de-bolota", is widely found in the Northern and Northeastern regions of Brazil. Its pods are used as cattle food supplement in the drought period. Compounds with a gastroprotective activity were obtained from the genus Parkia. Therefore, this study aimed at investigating the gastroprotective effect of the ethanolic extract of Parkia platycephala Benth. leaves (Pp-EtOH, as well as evaluating its possible mechanisms of action in experimental ulcer induction models. Lesions were induced by absolute ethanol, ethanol-HCl, ischemia-reperfusion and indomethacin in rodents. Pp-EtOH showed a protective effect in the lesion models (66, 48 and 52 %, respectively, but it was not able to protect gastric mucosa against indomethacin-induced lesions. Results show a possible participation of the NO-synthase pathway in the gastroprotection and an antioxidant activity, by the increase of the catalase activity. The participation of prostaglandins and potassium channels sensitive to ATP in the gastroprotective effect of Pp-EtOH seems less likely to occur. More comprehensive studies, therefore, should be carried out to elucidate the antiulcerative effects of this promising natural product against this gastrointestinal disorder.

  16. Causes and Treatment of Acute Ischemic Stroke During Pregnancy.

    Terón, Ina; Eng, Melissa S; Katz, Jeffrey M

    2018-05-21

    Treatment recommendations for pregnancy associated ischemic stroke are scarce. This may be due to the fact that, in general, obstetricians tend not to make recommendations for stroke patients and neurologists are not commonly involved in the care of pregnant women. Herein, we review the multiple etiologies of ischemic stroke during pregnancy, considerations for diagnostic testing, and acute treatment and prevention options, including associated risks specific to the pregnant and puerperal state. Intravenous tissue plasminogen activator (tPA) and endovascular thrombectomy have been used successfully to treat pregnant women with acute ischemic stroke. Recent national guidelines recommend considering tPA use during pregnancy for moderate and severe strokes if the potential benefits offset the risks of uterine hemorrhage. Pregnancy-associated ischemic stroke is rare, but can be devastating, and recanalization therapy should not be systematically withheld. Women who are at risk for stroke should be followed carefully, and providers caring for pregnant women should be educated regarding stroke signs and symptoms. Many of the standard post stroke diagnostic modalities may be used safely in pregnancy, and primary and secondary stroke prevention therapy must be tailored to avoid fetal toxicity.

    Full Text Available Riccardo Masetti, Andrea PessionPediatric Oncology and Hematology Unit “Lalla Seràgnoli”, University of Bologna, Bologna, ItalyAbstract: Acute lymphoblastic leukemia (ALL accounts for almost 4000 cases annually in the United States, approximately two thirds of which are in children and adolescents. Treatment results of ALL have improved considerably in the past decade, due to an optimal stratification of patients and a rational use of different antileukemic agents among which L-asparaginase (L-ASNase plays a fundamental role. This drug has been used in pediatric ALL chemotherapy protocols for almost 3 decades. In the 1970s and 1980s a chemically modified form of this enzyme called pegasparaginase (PEG-ASNase was rationally synthesized to decrease immunogenicity of the enzyme and prolong its half-life. The different advantages of PEG-ASNase have been demonstrated in many clinical studies, the last of which underline the utility of this drug in front-line therapy of ALL. In this review, we discuss the pharmacological advantages and clinical potential of PEG-ASNase and its important use in first-line treatment of ALL.Keywords: pegasparaginase, acute, lymphoblastic leukemia, pegylation

    Full Text Available First introduced into clinical practice in 1969, glibenclamide (US adopted name, glyburide is known best for its use in the treatment of diabetes mellitus type 2, where it is used to promote the release of insulin by blocking pancreatic KATP [sulfonylurea receptor 1 (Sur1-Kir6.2] channels. During the last decade, glibenclamide has received renewed attention due to its pleiotropic protective effects in acute CNS injury. Acting via inhibition of the recently characterized Sur1-Trpm4 channel (formerly, the Sur1-regulated NCCa-ATP channel and, in some cases, via brain KATP channels, glibenclamide has been shown to be beneficial in several clinically relevant rodent models of ischemic and hemorrhagic stroke, traumatic brain injury, spinal cord injury, neonatal encephalopathy of prematurity, and metastatic brain tumor. Glibenclamide acts on microvessels to reduce edema formation and secondary hemorrhage, it inhibits necrotic cell death, it exerts potent anti-inflammatory effects and it promotes neurogenesis—all via inhibition of Sur1. Two clinical trials, one in TBI and one in stroke, currently are underway. These recent findings, which implicate Sur1 in a number of acute pathological conditions involving the CNS, present new opportunities to use glibenclamide, a well-known, safe pharmaceutical agent, for medical conditions that heretofore had few or no treatment options.

    The nephroprotective effect of coenzyme Q10 was investigated in mice with acute renal injury induced by a single i.p. injection of cisplatin (5 mg/kg). Coenzyme Q10 treatment (10 mg/kg/day, i.p.) was applied for 6 consecutive days, starting 1 day before cisplatin administration. Coenzyme Q10 significantly reduced blood urea nitrogen and serum creatinine levels which were increased by cisplatin. Coenzyme Q10 significantly compensated deficits in the antioxidant defense mechanisms (reduced glutathione level and superoxide dismutase activity), suppressed lipid peroxidation, decreased the elevations of tumor necrosis factor-α, nitric oxide and platinum ion concentration, and attenuated the reductions of selenium and zinc ions in renal tissue resulted from cisplatin administration. Also, histopathological renal tissue damage mediated by cisplatin was ameliorated by coenzyme Q10 treatment. Immunohistochemical analysis revealed that coenzyme Q10 significantly decreased the cisplatin-induced overexpression of inducible nitric oxide synthase, nuclear factor-κB, caspase-3 and p53 in renal tissue. It was concluded that coenzyme Q10 represents a potential therapeutic option to protect against acute cisplatin nephrotoxicity commonly encountered in clinical practice.

    2017-03-01

    Topical cocaine is sometimes used for the treatment of epistaxis, as it has both potent anesthetic and vasoconstrictive properties. Cocaine has unpredictable cardiovascular effects, such as sudden hypertension, tachycardia, coronary arterial vasoconstriction, and dysrhythmia. We report a case of acute iatrogenic cardiovascular toxicity from the use of topical cocaine in a 56-year-old man presenting to the Emergency Department with profound epistaxis. To prepare for cauterization and nasal packing, the patient received 4% topical cocaine-soaked nasal pledgets. He became hypertensive, tachypneic, tachycardic, and dysphoric immediately after administration. To directly counter these adverse hyperadrenergic effects, the patient was given 10 mg intravenous labetalol, a mixed β- and α-blocker. This instantly normalized his vital signs and adverse subjective effects. His epistaxis was successfully treated, and he was discharged 1 h later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We believe that emergency physicians should be aware of the unpredictable acute cardiovascular toxicity of topical cocaine. Labetalol represents an effective first-line treatment, which, unlike benzodiazepines, directly counters the pharmacologic effects of cocaine and has no respiratory or sedative side effects. Labetalol, with its mixed β/α-blocking properties, also mitigates the potential for "unopposed α-stimulation." Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Recanalization of acute large artery occlusions is a strong predictor of good outcome. The development of thrombectomy devices resulted in a significant improvement in recanalization rates compared to thrombolytics alone. However, clinical trials and registries with these thrombectomy devices in acute ischemic stroke (AIS have shown recanalization rates in the range of 40-81%. The last decade has seen the development of nickel titanium self-expandable stents (SES. These stents, in contrast to balloon-mounted stents, allow better navigability and deployment in tortuous vessels and therefore are optimal for the cerebral circulation. SES were initially used for stent-assisted coil embolization of intracranial aneurysms and for treatment of intracranial stenosis. However, a few authors have recently reported feasibility of deployment of SES in AIS. The use of these devices yielded higher recanalization rates compared to traditional thrombectomy devices. Encouraged by these results, retrievable SES systems have been recently used in AIS. These devices offer the advantage of resheathing and retrieving of the stent even after full deployment. Some of these stents can also be detached in case permanent stent placement is needed. Retrievable SES are being used in Europe and currently tested in clinical trials in the United States. We review the recent literature in the use of stents for the treatment of AIS secondary to large vessel occlusion.

    Full Text Available BackgroundAxillary osmidrosis is characterized by unpleasant odors originating from the axillary apocrine glands, resulting in psychosocial stress. The main treatment modality is apocrine gland removal. Until now, of the various surgical techniques have sometimes caused serious complications. We describe herein the favorable outcomes of a new method for ablating apocrine glands by minimal subdermal shaving using sclerotherapy with absolute ethanol.MethodsA total of 12 patients underwent the procedure. The severity of osmidrosis was evaluated before surgery. Conventional subdermal shaving was performed on one side (control group and ablation by means of minimal subdermal shaving and absolute ethanol on the other side (study group. Postoperative outcomes were compared between the study and control groups.ResultsThe length of time to removal of the drain was 1 day shorter in the study group than in the control group. There were no serious complications, such as hematoma or seroma, in either group, but flap margin necrosis and flap desquamation occurred in the control group, and were successfully managed with conservative treatment. Six months after surgery, we and our patients were satisfied with the outcomes.ConclusionsSclerotherapy using absolute ethanol combined with minimal subdermal shaving may be useful for the treatment of axillary osmidrosis. It can reduce the incidence of seroma and hematoma and allow the skin flap to adhere to its recipient site. It can degrade and ablate the remaining apocrine glands and eliminate causative organisms. Furthermore, since this technique is relatively simple, it takes less time than the conventional method.

    Pregabalin has demonstrated anti-hyperalgesic properties and was introduced into acute pain treatment in 2001. Our aim was to evaluate the beneficial and harmful effects of pregabalin in postoperative pain management. We included randomized clinical trials investigating perioperative pregabalin......, Peto's odds ratio was 2.9 (1.2, 6.8; TSA adjusted confidence interval: 0.1, 97.1). Based on trials with low risk of bias, pregabalin may have a minimal opioid-sparing effect, but the risk of SAEs seems increased. However, the GRADE-rated evaluations showed only moderate to very low quality of evidence....... Consequently, a routine use of pregabalin for postoperative pain treatment cannot be recommended....

    Medicinal plants have contributed significantly to current malaria treatment. Emergence of resistance to currently available drugs has necessitated the search for new plant-based anti-malarial agents and several plant-based, pharmacologically active anti-malarial compounds have been isolated. This study was conducted to validate the traditional usage of Echinops kebericho for treating malaria in the traditional health care system of Ethiopia. The roots of E. kebericho were collected from Masha Woreda, Sheka Zone. After collection, the plant materials were identified by a taxonomist, dried under shade and crushed to powder for extraction. The powdered roots were extracted by maceration using 70 % ethanol. Acute toxicity study of the crude extract was carried out in Swiss albino mice. The in vivo anti-malarial activity of plant extract (200, 350 and 500 mg/kg) of E. kebericho roots against a chloroquine (CQ) sensitive strain of Plasmodium berghei strain ANKA was assessed using the four-day suppressive test procedure. Parameters such as parasitaemia, packed cell volume, body weight and survival time were then determined using standard tests. Oral administration of the ethanol extract showed significant (P<0.001) parasitaemia suppression at dose levels of 350 and 500 mg/kg in dose-related manner compared with the negative control. Five hundred mg/kg showed the highest (57.29±1.76 %) parasitaemia suppression. The survival times of P. berghei-infected mice were also increased in a dose-dependent manner but the test material did not prevent weight loss associated with increased parasitaemia. The result also showed the plant material prevented the loss in packed cell volume associated with increased parasitaemia. Its oral LD50 was found to be greater than 5,000 mg/kg, indicating its wider safety margin in mice. The result revealed the ethanol extract of E. kebericho roots has anti-malarial activity against P. berghei in an animal model and lends support to the use of the

    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.

    Family Centered Brief Intensive Treatment (FC BIT), a hospital diversion treatment program for individuals with acute suicidal ideation, was developed to treat suicidal clients and their families. Individuals who met criteria for hospitalization were treated as outpatients using FC BIT (n = 19) or an intensive outpatient treatment without the family component (IOP; n = 24). Clients receiving FC BIT identified family members or supportive others to participate in therapy. FC BIT clients had significantly greater improvement at the end of treatment compared to IOP clients on measures of depression, hopelessness, and suicidality. Further research is needed to test the efficacy of FC BIT. © 2014 The American Association of Suicidology.

    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

    In the rat, binge-like ethanol (EtOH) exposure during the early neonatal period (a developmental period equivalent to the human third trimester) can result in a permanent deficit of cerebellar Purkinje cells (Pcells). However, the consequences of a moderate binge alcohol exposure on a single day during this postnatal period have not been established. This is an issue of importance as many pregnant women binge drink periodically at social drinking levels. This study aimed to identify both the acute and long-term effects of exposure to a single alcohol binge that achieved a mean peak blood EtOH concentration of approximately 250 mg/dl during early postnatal life using a rat model of fetal alcohol spectrum disorders. Acute apoptotic Pcell death 10 hours after a moderate dose binge EtOH exposure from postnatal days (PDs) 0 to 10 was assessed using active caspase-3 immunolabeling. Acute Pcell apoptosis was quantified in cerebellar vermal lobules I-X using the physical disector method. Long-term effects were assessed at PD 60 using stereological methods to determine total Pcell numbers in the vermis, lobule III, and lobule IX, following a moderate dose binge EtOH exposure at PDs 0, 2, or 4. Acute apoptosis was induced by EtOH on PDs 1 to 8 in a time and lobular-dependent manner. For EtOH exposure on PD 2, significant long-term Pcell loss occurred in lobule III. EtOH exposure on PD 4 resulted in significant long-term Pcell loss throughout the entire vermis. These results indicate that a single, early EtOH episode of moderate dose can create significant and permanent Pcell loss in the developing cerebellum.

    In perfused rat liver, the inhibition of ethanol uptake by ouabain does not follow the rapid inhibition of the Na+ K+- activated ATPase as assessed by changes in perfusate [K+] (half-time, t 1/2 = 2--3 min), but correlated rather with the slow inhibition of oxygen uptake (maximal inhibition = 40% in 20 min). The data indicate that ouabain exerts its effect on ethanol metabolism via the following sequence of events; inhibition of the sodium pump is followed gradually by a perturbation of the intracellular cation milieu; this leads to an inhibition of the mitochondrial respiratory chain, resulting in diminished rate of NADH oxidation, which in turn causes in inhibition of ethanol metabolism.

  15. Acute drug treatment in the early C. elegans embryo.

    Directory of Open Access Journals (Sweden)

    Ana Carvalho

    Full Text Available Genetic and genome-wide RNAi approaches available in C. elegans, combined with tools for visualizing subcellular events with high-resolution, have led to increasing adoption of the early C. elegans embryo as a model for mechanistic and functional genomic analysis of cellular processes. However, a limitation of this system has been the impermeability of the embryo eggshell, which has prevented the routine use of small molecule inhibitors. Here, we present a method to permeabilize and immobilize embryos for acute inhibitor treatment in conjunction with live imaging. To identify a means to permeabilize the eggshell, we used a dye uptake assay to screen a set of 310 candidate genes defined by a combination of bioinformatic criteria. This screen identified 20 genes whose inhibition resulted in >75% eggshell permeability, and 3 that permeabilized embryos with minimal deleterious effects on embryo production and early embryonic development. To mount permeabilized embryos for acute drug addition in conjunction with live imaging, we combined optimized inhibition of one of these genes with the use of a microfabricated chamber that we designed. We demonstrate that these two developments enable the temporally controlled introduction of inhibitors for mechanistic studies. This method should also open new avenues of investigation by allowing profiling and specificity-testing of inhibitors through comparison with genome-wide phenotypic datasets.

    Full Text Available Among the sickly children, pharyngitis and tonsillopharyngitis are quite often accompanied by pain and scratch in a throat, which is anguished for a child themselves and causes parents to worry. In the therapy for the indicated pathology, a certain place is held by a local antibiotic fusafungine. In the article, the author studies the effects of fusafungine on tonsillitis/tonsillopharyngitis and pharyngitis, running with pain in a throat, among the sickly children aged between 3 and 15. The research was carried on in 42 centers of different Russian regions and became a part of the multicentered research according to «Chibis» program. 2,609 children were examined, 1,907 of who Received fusafungine and 702 children did not. Among 78,1% of the children, the authors noted the phenomena of pharyngitis, rhinopharyngitis and acute tonsillopharyngitis. As the research showed the symptoms of rhinopharyngitis and tonsillopharync gitis were reliably arrested much faster, when applying fusafungine, thus, the clinical effects mostly emerged after 4th–5th day of the therapy. The acquired data allowed one to recommend the inclusion of fusafungine into the therapy for acute rhinopharyngitis, pharyngitis and tonsillopharyngitis among the sickly children.Key words: rhinopharyngitis, pharyngitis, tonsillopharyngitis, fusafungine, children, treatment.

  17. Acute symptomatic neonatal seizures in preterm neonates: etiologies and treatments.

    2017-12-15

    Acute symptomatic neonatal seizures in preterm newborns are a relevant clinical challenge due to the presence of many knowledge gaps. Etiology-wise, acute symptomatic seizures have an age-specific epidemiology, with intraventricular hemorrhage and its complications representing the first cause in extremely and very preterm neonates, whereas other etiologies have similar occurrence rates as in full-term infants. Specific treatment strategies for the premature neonates are not yet available. Studies suggest a similarly low response rate with even more unfavorable prognosis than in full-term infants. Pharmacodynamic and pharmacokinetic changes are likely under way during the preterm period, with the potential to affect both effectiveness and safety of antiepileptic drugs in these patients. However, due to the lack of clear evidence to guide prioritization of second-line drugs, off-label medications are frequently indicated by review papers and flow-charts, and are prescribed in clinical practice. We therefore conclude by exploring potential future lines of research. Copyright © 2017 Elsevier Ltd. All rights reserved.

    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.

    In recent years, new opportunities have emerged that have the potential to change rapidly the therapeutic scenario of patients with acute venous thromboembolism (VTE). Selected patients with deep vein thrombosis (DVT) can be treated effectively and safely at home with fixed doses of low molecular weight heparins. The prompt administration of compression elastic stockings in addition to anticoagulant drugs in patients with acute DVT has the potential to halve the rate of late postthrombotic sequelae. The long-term use of low molecular weight heparins is likely to be more effective than oral anticoagulants for the secondary prevention of VTE in patients with advanced malignancy. Patients with pulmonary embolism and right ventricular dysfunction might benefit from the early administration of thrombolytic drugs in combination with heparin to a greater extent than from heparin alone. Despite an impressive amount of clinical information on the proper duration of oral anticoagulants in patients with unprovoked VTE, the optimal long-term treatment of these patients remains undefined. Finally, new categories of drugs are emerging that have the potential to replace conventional anticoagulants in the near future. They include compounds that inhibit factor Xa or thrombin.

This is complex pathological condition in 90 % of cases caused by colorectal cancer (CRC.Objective – to evaluate radicality of the performed operations in complicated colorectal cancer in general surgical hospitals. Dependence of the severity of intestinal obstruction by tumor localization, its morphological characteristics, determine dependence of the type of the surgical operation performed on the severity of intestinal obstruction.Materials and methods. We have studied the data on 667 patients with colorectal cancer complicated by acute intestinal obstruction. These patients were treated in the period from 2001 to 2013 in general surgical hospital in the territory of Smolensk and Smolensk region. For the processing of the obtained results we have used software Statistica 6.1. Differences were considered statistically at p ≤ 0.05.Results. All the patients were divided into 3 groups by the expression of intestinal obstruction. Group 1 (n = 279 consisted of patients with the presence of decompensated intestinal obstruction (DIO, group 2 (n = 313 consisted of patients with subcompensated intestinal obstruction (SIO, group 3 (n = 75 included patients with compensated intestinal obstruction (CIO. In case of tumor localization in right halfof the colon we most commonly observed clinical picture of acute development of decompensated intestinal obstruction (p = 0.041. Subcompensated intestinal obstruction prevailed in case of tumor localization in left half of the colon and rectal localization. In general surgical hospitals it is not always possible to speak about radicality of surgical treatment, as in a large number of cases (62.5 % the number of examined lymph nodes was less than 4.

    2011-01-01

    Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

    Highlights: Black-Right-Pointing-Pointer A simple ethanol vapour post-treatment was applied to the TiO{sub 2} electrode in a DSSC. Black-Right-Pointing-Pointer A stable efficiency improvement was evident after this post-treatment. Black-Right-Pointing-Pointer Structural and chemical modifications of the treatment were systematically investigated using advanced electron microscopy. Black-Right-Pointing-Pointer Morphology changes in favour of the efficiency improvement were identified (increased porosity and reduced TiO{sub 2} particle size). Black-Right-Pointing-Pointer EELS study confirmed that stronger coupling formed between the dye and the treated TiO{sub 2}. - Abstract: TiO{sub 2} based dye-sensitized solar cells (DSSCs) have great potential to solve many energy challenges, however, their low energy conversion rate is still a barrier for further applications. Ethanol vapour post-treatment can improve the DSSC's conversion efficiency without changing its architecture, and a stable 2-3% improvement was found in our experiments. Microstructural and chemical factors were investigated using scanning electron microscopy and analytical electron microscopy on treated and untreated electrodes. The vapour treatment improved the porosity and surface-to-volume ratio of the TiO{sub 2} particles, decreased electron transport loss between TiO{sub 2} and fluorine doped tin oxide, and increased hydroxyl sites on the TiO{sub 2} particle's surface. The modification therefore enhanced the dye uptake and dye-TiO{sub 2} coupling, and it reduced the energy loss during the carrier transfer.

    Recent years have highlighted significant progress in understanding the underlying genetic and epigenetic signatures of acute myeloid leukemia(AML). Most importantly, novel chemotherapy and targeted strategies have led to improved outcomes in selected genetic subsets. AML is a remarkably heterogeneous disease, and individualized therapies for disease-specific characteristics (considering patients’ age, cytogenetics, and mutations) could yield better outcomes. Compared with the historical 5-to 10-year survival rate of 10%, the survival of patients who undergo modern treatment approaches reaches up to 40–50%, and for specific subsets, the improvements are even more dramatic; for example, in acute promyelocytic leukemia, the use of all-trans retinoic acid and arsenic trioxide improved survival from 30–40% up to 80–90%. Similar progress has been documented in core-binding-factor-AML, with an increase in survival from 30% to 80% upon the use of high-dose cytarabine/fludarabine/granulocyte colony-stimulating factor combination regimens. AML treatment was also recently influenced by the discovery of the superiority of regimens with higher dose Ara-C and nucleoside analogues compared with the “7+3” regimen, with about a 20% improvement in overall survival. Despite these significant differences, most centers continue to use the “7+3” regimen, and greater awareness will improve the outcome. The discovery of targetable molecular abnormalities and recent studies of targeted therapies (gemtuzumab ozagomycin, FLT3 inhibitors, isocitrate dehydrogenase inhibitors, and epigenetic therapies), future use of checkpoint inhibitors and other immune therapies such as chimeric antigen receptor T-cells, and maintenance strategies based on the minimal residual disease evaluation represent novel, exciting clinical leads aimed to improve AML outcomes in the near future.

    2012-11-01

    In spite of being the fastest acting drug available for the control of an acute gout attack, colchicine is generally considered a last alternative in gout therapy. This is mainly due to the severe adverse effects associated with its administration through the enteral and parenteral routes, as well as its high risk/benefit ratio. The preparation of dosage forms of colchicine that can be administered by alternative routes is therefore a beneficial exercise. Among the formulable substitute dosage forms of colchicine, its ointment seems to be the best option available due to its ability to deliver the drug transdermally as well as its ease of preparation and evaluation. In this study, we prepared and tested 0.2% and 0.5% colchicine ointments for their effectiveness in delivering colchicine transdermally. Colchicine ointment was prepared using a self-formulated water-in-oil type of emulsion ointment base, with the colchicine dissolved in the water portion of the ointment base. In vitro drug release studies were carried out using the Franz diffusion test apparatus and an ultraviolet (UV)-visible spectrophotometer was used to quantify the drug in the samples. Rabbits were used as test animals for in vivo studies and the blood samples were analysed using the UV-visible spectrophotometer. Colchicine was found to be well-absorbed transdermally, although absorption was not 100%. No side effects were associated with its 0.2% formulation. Ointments containing colchicine in low concentrations may be a feasible and effective treatment option for the prevention and treatment of acute gout attacks.

    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.

    During an outbreak of mass methanol poisoning in the Czech Republic in 2012-2014, we compared the total hospital costs and one-year medical costs in the patients treated with different antidotes (fomepizole versus ethanol) and modalities of hemodialysis (intermittent hemodialysis, IHD, versus continuous renal replacement therapy, CRRT). Cross-sectional study in 106 patients with confirmed diagnosis treated in 30 ICU settings. For each patient, the following data were analyzed: admission laboratory data, GCS, PSS, ICU length of stay, organ failures, treatment, outcome, and total hospital costs. Of 83 survivors, in 54 (65%) patients the follow-up examination, quality of life measurement with SF36 questionnaire two years after discharge, and one-year medical costs analysis were performed. The median total hospital costs were 7200 (IQR 1500-10,900) euros and the median one-year medical costs were 1447 (IQR 133-1163) euros in the study population. The total hospital costs were higher in the patients treated with fomepizole comparing to ethanol: 12,890 (IQR 6910-16,210) versus 5590 (IQR 1430-6940) euros (ppoisoning was 3.30 (1.70-3.80 CI 95%), p0.05). The total hospital costs in the patients with acute methanol poisoning were more than three times higher in the patients treated with fomepizole than in the patients treated with ethanol after adjustment for the severity of poisoning. The dialysis modality did not affect the total hospital costs, but the trend to lower costs was present in IHD-group. Copyright © 2017 Elsevier Inc. All rights reserved.

    Chronic alcohol intake is associated with widespread disruptions in sleep and circadian rhythms in both human alcoholics and in experimental animals. Recent studies have demonstrated that chronic and acute ethanol treatments alter fundamental properties of the circadian pacemaker--including free-running period and responsiveness to photic and nonphotic phase-shifting stimuli--in rats and hamsters. In the present work, the authors extend these observations to the C57BL/6J mouse, an inbred strain characterized by very high levels of voluntary ethanol intake and by reliable and stable free-running circadian activity rhythms. Mice were housed individually in running-wheel cages under conditions of either voluntary or forced ethanol intake, whereas controls were maintained on plain water. Forced ethanol intake significantly attenuated photic phase delays (but not phase advances) and shortened free-running period in constant darkness, but voluntary ethanol intake failed to affect either of these parameters. Thus, high levels of chronic ethanol intake, beyond those normally achieved under voluntary drinking conditions, are required to alter fundamental circadian pacemaker properties in C57BL/6J mice. These observations may be related to the relative ethanol insensitivity displayed by this strain in several other phenotypic domains, including ethanol-induced sedation, ataxia, and withdrawal. Additional experiments will investigate chronobiological sensitivity to ethanol in a range of inbred strains showing diverse ethanol-related phenotypes.

    Purpose: To evaluate the impact of the use of radiotherapy to preserve the renal graft in patients with recurrent graft rejection that failed to respond to medical treatment and identify risk factors to predict the probability of graft loss. Material and Methods: Between June 1989 and December 1995, 53 renal graft recipients were treated at our institution after experiencing several episodes of rejection. Rejection was defined as an unexplained, consecutive, daily rise in serum creatinine. Each episode was confirmed with renal biopsy. Patients who experienced rejection were initially treated with solu medrol bolus and prednisone. Patients with steroid-resistant or recurrent rejection received OKT3, polyclonal antilymphocyte antibody, FK506, or mycophenolate mofetil. Those who failed to respond to medical treatment were referred for radiotherapy. Treatment consisted of a dose of 600 cGy given in 3 or 4 fractions using 6 MV photons, AP or AP/PA. All patients underwent ultrasound kidney localization; a 2 cm margin was given around the kidney. Results: Median follow-up from the date of transplant to the last follow-up was 22 months (range 1-83 months), the median time from the date of transplant to the initiation of radiotherapy was 3 months, and the median time from the initiation of radiotherapy to the last follow up was 10 months (range 0.1 to 64 months). Of these 34 men and 19 women, median age of 3), Ninety-one percent were cadaveric transplant recipients., human leukocyte antigen matching on HLA-A and HLA-B (zero antigens in 26 patients/one or two shared antigens in 27 patients), HLA-DR locus (zero antigens in 34 patients/one or two shared antigens in 19 patients), transplant panel-reactive antibodies at transplantation (median PRA-Curr of 3% and median PRA-Max of 8%), number of acute rejection episodes, interval from the date of the transplant to the first rejection (median 1 month, range 5 days to 68 months), serum creatinine levels at the time of the first

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.

    Rheumatic heart disease remains an important cause of acquired heart disease in developing countries. Although prevention of rheumatic fever and management of recurrences have been well established, optimal management of active rheumatic carditis remains unclear. This is an update of a review published in 2003, and previously updated in 2009 and 2012. To assess the effects, both harmful and beneficial, of anti-inflammatory agents such as aspirin, corticosteroids and other drugs in preventing or reducing further valvular damage in patients with acute rheumatic fever. We searched the Cochrane Central Register of Controlled Trials (2013, Issue 9 of 12), MEDLINE (Ovid, 1948 to 2013 October Week 1), EMBASE (Ovid, 1980 to 2013 Week 41) and Latin American Caribbean Health Sciences Literature (LILACS) (1982 to 17 October 2013). We last searched Index Medicus (1950 to April 2001) in 2001. We checked reference lists of identified studies and applied no language restrictions. Randomised controlled trials comparing anti-inflammatory agents (e.g. aspirin, steroids, immunoglobulins, pentoxifylline) versus placebo or controls, or comparing any of the anti-inflammatory agents versus one another, in adults and children with acute rheumatic fever diagnosed according to Jones, or modified Jones, criteria. The presence of cardiac disease one year after treatment was the major outcome criterion selected. Two review authors extracted data and assessed risk of bias using the methodology outlined in the Cochrane Handbook of Systematic Reviews of Interventions. Standard methodological procedures as expected by The Cochrane Collaboration were used. No new studies were included in this update. Eight randomised controlled trials involving 996 people were selected for inclusion in the review. Researchers compared several steroidal agents such as corticotrophin, cortisone, hydrocortisone, dexamethasone, prednisone and intravenous immunoglobulin versus aspirin, placebo or no treatment. Six

    A 49 years old female patient entered the surgical department because of epigastric and ileocoecal pains with the symptoms of acute abdomen. A surgical intervention was performed because of supposed appendicitis, but it was not verified. During the surgical observation the patient was confused and negativistic so she was transferred to the psychiatric department. Because of loss of 20 kg weight, high blood sedimentation and anaemia she was sent to our department with the suspicion of an organic disease. A moderate exophthalmos, glittering eyes and Graefe's sign was noted, therefore hyperthyroidism was diagnosed, which was proved by Kocher's blood picture, low serum cholesterol, extremely high T3 and T4 level, and iodine storage diagram. The antithyreotic treatment resulted a dramatic improvement in the extremely serious moreover hopeless case and after a long-term treatment the patient became symptom-free without complaints. Later because of regression of hyperthyreoidism and the growing nodular goitre the patient was treated on two occasions with radioactive iodine. At present the patient is in remission.

    Population-based data on more than 1 million patients registered in the Surveillance, Epidemiology, and End-Results Program of the National Cancer Institute, 1973-1984, were analyzed to determine the survival of patients with de novo acute nonlymphocytic leukemia (ANLL) and following a first primary tumor treated (with chemotherapy and/or radiation therapy) or untreated. Cases that occurred within 12 months of the first malignant neoplasm were excluded. Survival was estimated using Cox proportional-hazards modeling, with age, sex, and specific type of ANLL as covariates. The 6,271 patients with de novo ANLL had an estimated 12-month survival of 30%, while the 107 patients with treatment-related ANLL had an estimated 12-month survival of 10%. The authors conclude that ANLL that occurs after chemotherapy or radiation therapy is biologically more aggressive and/or resistant to therapy than spontaneous ANLL. This provides a rationale for current studies on treatment-induced cellular changes and on more aggressive therapy for these patients

    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.

    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.

    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.

    Most patients with acute poisoning are treated as outpatients worldwide. In Oslo, these patients are treated in a physician-led outpatient clinic with limited diagnostic and treatment resources, which reduces both the costs and emergency department overcrowding. We describe the poisoning patterns, treatment, mortality, factors associated with hospitalization and follow-up at this Emergency Medical Agency (EMA, "Oslo Legevakt"), and we evaluate the safety of this current practice. All acute poisonings in adults (> or = 16 years) treated at the EMA during one year (April 2008 to April 2009) were included consecutively in an observational study design. The treating physicians completed a standardized form comprising information needed to address the study's aims. Multivariate logistic regression analysis was used to identify the factors associated with hospitalization. There were 2348 contacts for 1856 individuals; 1157 (62%) were male, and the median age was 34 years. The most frequent main toxic agents were ethanol (43%), opioids (22%) and CO or fire smoke (10%). The physicians classified 73% as accidental overdoses with substances of abuse taken for recreational purposes, 15% as other accidents (self-inflicted or other) and 11% as suicide attempts. Most (91%) patients were treated with observation only. The median observation time until discharge was 3.8 hours. No patient developed sequelae or died at the EMA. Seventeen per cent were hospitalized. Gamma-hydroxybutyric acid, respiratory depression, paracetamol, reduced consciousness and suicidal intention were factors associated with hospitalization. Forty-eight per cent were discharged without referral to follow-up. The one-month mortality was 0.6%. Of the nine deaths, five were by new accidental overdose with substances of abuse. More than twice as many patients were treated at the EMA compared with all hospitals in Oslo. Despite more than a doubling of the annual number of poisoned patients treated at the EMA

    Full Text Available Over the last 20 years, after combining treatment of chemotherapy and radiotherapy, there has been an improvement in the survival rate of acute lymphoblastic leukemia patients, with a current cure rate of around 70%. Children with the disease have been enrolled into international treatment protocols designed to improve survival and minimize the serious irreversible late effects. Our oncology unit uses the international protocol: GBTLI LLA-85 and 90, with the drugs methotrexate, cytosine, arabinoside, dexamethasone, and radiotherapy. However, these treatments can cause gonadal damage and growth impairment. PATIENTS AND METHOD: The authors analyzed 20 children off therapy in order to determine the role of the various doses of radiotherapy regarding endocrinological alterations. They were divided into 3 groups according to central nervous system prophylaxis: Group A underwent chemotherapy, group B underwent chemotherapy plus radiotherapy (18 Gy, and group C underwent chemotherapy plus radiotherapy (24 Gy. Serum concentrations of LH, FSH, GH, and testosterone were determined. Imaging studies included bone age, pelvic ultrasound and scrotum, and skull magnetic resonance imaging. RESULTS: Nine of the patients who received radiotherapy had decreased pituitary volume. There was a significant difference in the response to GH and loss of predicted final stature (Bayley-Pinneau between the 2 irradiated groups and the group that was not irradiated, but there was no difference regarding the radiation doses used (18 or 24 Gy. The final predicted height (Bayley-Pinneau was significantly less (P = 0.0071 in both groups treated with radiotherapy. Two girls had precocious puberty, and 1 boy with delayed puberty presented calcification of the epididymis. CONCLUSION: Radiotherapy was been responsible for late side effects, especially related to growth and puberty.

    Hallucinogenic drugs were used to treat alcoholic patients in the past, and recent developments in the study of hallucinogens led to a renewal of interest regarding the application of these drugs in the treatment of addiction. In this scenario, accumulating evidence suggests that the hallucinogenic brew ayahuasca (Aya) may have therapeutic effects on substance abuse problems. We investigated the effects of Aya on spontaneous locomotor activity and ethanol(Eth)-induced hyperlocomotion and subsequent locomotor sensitization by a two-injection protocol. Additionally, we tested the effect of Aya on an 8-day counter-sensitization protocol to modify sensitized responses induced by a repeated treatment with Eth (1.8g/kg) for 8 alternate days. Aya showed high sensitivity in preventing the development of Eth-induced behavioral sensitization, attenuating it at all doses (30, 100, 200, 300 or 500 mg/kg) without modifying spontaneous locomotor activity. At the highest doses (300 and 500 mg/kg), Aya also showed selectivity to both acute and sensitized Eth responses. Finally, a counter-sensitization strategy with 100 or 300 mg/kg of Aya for 8 consecutive days after the establishment of Eth-induced behavioral sensitization was effective in blocking its subsequent expression on an Eth challenge. We demonstrated that Aya not only inhibits early behaviors associated with the initiation and development of Eth addiction, but also showed effectiveness in reversing long-term drug effects expression, inhibiting the reinstatement of Eth-induced behavioral sensitization when administered in the Eth-associated environment.

    Dilute-acid pretreatment of lignocellulosic biomass enhances the ability of enzymes to hydrolyze cellulose to glucose, but produces many toxic compounds that inhibit fermentation of sugars to ethanol. The objective of this study was to compare the effectiveness of treating hydrolysate liquor with Ca(OH)2 and NH4OH for improving ethanol yields. Corn stover was pretreated in a pilot-scale reactor and then the liquor fraction (hydrolysate) was extracted and treated with various amounts of Ca(OH)2 or NH4OH at several temperatures. Glucose and xylose in the treated liquor were fermented to ethanol using a glucose-xylose fermenting bacteria, Zymomonas mobilis 8b. Sugar losses up to 10% occurred during treatment with Ca(OH)2, but these losses were two to fourfold lower with NH4OH treatment. Ethanol yields for NH4OH-treated hydrolysate were 33% greater than those achieved in Ca(OH)2-treated hydrolysate and pH adjustment to either 6.0 or 8.5 with NH4OH prior to fermentation produced equivalent ethanol yields.

    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

    Gemtuzumab ozogamicin (GO) is an antibody-drug conjugate consisting of a monoclonal antibody targeting CD33 linked to a cytotoxic derivative of calicheamicin. Despite the known clinical efficacy in relapsed/refractory acute myeloid leukemia (AML), GO was withdrawn from the market in 2010 due to increased early deaths witnessed in newly diagnosed AML patients receiving GO + intensive chemotherapy. In 2017, new data on the clinical efficacy and safety of GO administered on a fractionated-dosing schedule led to re-approval for newly diagnosed and relapsed/refractory AML. Areas covered: Addition of fractionated GO to chemotherapy significantly improved event-free survival of newly diagnosed AML patients with favorable and intermediate cytogenetic-risk disease. GO monotherapy also prolonged survival in newly diagnosed unfit patients and relapse-free survival in relapsed/refractory AML. This new dosing schedule was associated with decreased incidence of hepatotoxicity, veno-occlusive disease, and early mortality. Expert commentary: GO represents the first drug-antibody conjugate approved (twice) in the United States for AML. Its re-emergence adds a valuable agent back into the armamentarium for AML. The approval of GO as well as three other agents for AML in 2017 highlights the need for rapid cytogenetic and molecular characterization of AML and incorporation into new treatment algorithms.

  9. Successful Treatment of Acute Lethal Dose of Acrylamide Poisoning

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Background: Acrylamide (C3H5NO is a vinyl monomer. This water-soluble crystalline solid is a colorless, odorless agent which is used in scientific laboratories and some industries. Acrylamide has cellular oxidative effects. Acute or chronic poisoning with this agent happens as a result of skin, respiratory, or oral contacts. Clinical manifestations depend on the dose, duration, and frequency of contact. Management of these patients consists of conservative and palliative therapies to reduce the oxidative effects. Case: The case was a 29-year-old girl with a Master of Sciences degree in genetics who worked in a university research center with previous history of depression. She had ingested 100cc of 30% Acrylamide solution for intentional suicide attempt. The patient was successfully managed using N-acetyl cysteine, vitamin C, and melatonin. Conclusion: Early diagnosis and appropriate treatment with recommended agents together with supportive therapies can save the life of patients exposed to potentially lethal doses of acrylamide, although intentional or accidental.

  10. Acute Abdomen in Interstitial Ectopic Pregnancy, An Emergency Laparoscopic Treatment

    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.

    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.

    Kaplan, Jason B; Grischenko, Marina; Giles, Francis J

    2015-12-01

    Acute lymphoblastic leukemia (ALL) is a potentially fatal disease that involves clonal expansion of early lymphoid progenitor cells. Much of drug development for ALL treatment involves targeting antigens of the clonal cell surface. Blinatumomab belongs to an emerging class of anti-cancer therapeutics referred to as bispecific T-cell engaging antibodies. The Food and Drug Administration approved its use in relapsed or refractory adult Philadelphia chromosome-negative B-cell precursor ALL in December of 2014. Blinatumomab contains both an anti-CD3 and anti-CD19 arm, allowing for the juxtaposition of CD3+ T-cells to malignant CD19+ B-cells, thereby resulting in granzyme- and perforin-mediated B-cell apoptosis. Preclinical studies suggest that blinatumomab's efficacy is related to the effector-to-target ratio and to the difference between its affinity for CD19 and CD3. Preclinical and early phase clinical studies have allowed for the characterization of the pharmacokinetics of blinatumomab, including the determination of its short half-life. The metabolic pathway has not been fully characterized but is thought to be similar to that of other antibodies. Phase I and II studies led to the identification of an ideal stepwise dose, involving long-term continuous intravenous infusion (CIVI), to optimize its efficacy and reduce the risk of certain toxicities. A high remission rate and duration were noted among a relapsed/refractory population of patients. The results of clinical trials have identified cytokine release syndrome and neurotoxicity, among others, as serious drug-related toxicities, leading to the institution of a Risk Evaluation and Mitigation Strategy. Blinatumomab represents a significant addition to the treatment options for ALL, but it is not without its limitations, of which are its short-half life, necessitating long-term CIVI, and the eventual emergence of CD19-negative clones. Continual development of the agent involves assessing its role in the frontline

    2005-05-01

    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 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. (orig.) [German] Jeder akute Schlaganfall ist ein Notfall und muss sofort in einer spezialisierten Klinik, am besten einer Stroke Unit, behandelt werden.

    Objective: To discuss the clinical characteristics of acute renal infarction and to evaluate the endovascular interventional therapy in treating acute renal infarction. Methods: Since 2006, six patients with acute renal infarction were encountered in our hospital. Renal arterial suction and thrombolytic therapy were immediately carried out as soon as the diagnosis was confirmed. The clinical data were retrospectively analyzed. Results: Based on clinical manifestations, enhanced CT scan and angiography, the diagnosis of acute renal infarction was definitely confirmed in all 6 patients. After renal arterial suction and thrombolytic therapy the clinical symptoms were markedly relieved and the blood flow in infracted area completely or partially returned to normal. Conclusion: The clinical presentation of acute renal infarction is not characteristic. For the diagnosis of acute renal infarction contrast-enhanced CT scanning and renal angiography are the exams of first choice. Renal artery suction and thrombolytic therapy is a safe and effective treatment for acute renal infarction. (authors)

    This study investigated the effect of atmospheric pressure plasma (APP) treatment on nitrite content and functionality of plant extracts. Ethanolic extracts of Perilla frutescens (EEP) were prepared and treated with APP for 60min. Nitrite content increased from 0 to 45.8mg/l in EEP after APP treatment for 60min. Antimicrobial activity of EEP against Clostridium perfringens and Salmonella Typhimurium was increased by APP with no influence on antioxidative activity (p<0.05). Lyophilized EEP (LEEP) treated with APP for 60min contained 3.74mg/g nitrite. The control (LEEP without APP) contained no nitrite. The minimum inhibitory concentration (MIC) of LEEP for C. perfringens was 200µg/ml. The control did not inhibit C. perfringens growth between 25 and 1000µg/ml. MICs of LEEP and the control against S. Typhimurium were 25 and 50µg/ml, respectively. New nitrite sources with increased antimicrobial activity can be produced from natural plants by APP treatment. Copyright © 2017 Elsevier Ltd.

    Aim of this review is to describe the role of clinical toxicology in the context of acute medicine. A special focus is put on antidotes and important aspects of diagnosis and therapy of acute intoxications. The data of the annual report of GIZ-Nord Poisons Centre is analyzed concerning the following aspects: what intoxications are relevant in acute medicine, are there special aspects in therapy, e.g. antidotes, and what antidotes are relevant? More over intoxication-related fatalities are analyzed. In 2015 the poisons centre was consulted in 33,000 cases of acute intoxications. The most important groups are drugs (e.g. antidepressants, beta blockers and calcium channel blockers), chemical products (e.g. products containing surfactant, corrosive substances and toxic alcohols like methanol), plants and recreational drugs. Intoxications are relevant in acute medicine. Some substances can cause fatal intoxications. Important antidotes are naloxone for opiods, acetylcystein for paracetamol, fomepizole and ethanol for toxic alcohols and diazepam for intoxications caused by chloroquine.

    Full Text Available Sulfate-rich mine water must be treated before it is released into natural water bodies. We tested ethanol as substrate in bioreactors designed for biological sulfate removal from mine water containing up to 9 g L−1 sulfate, using granular sludge from an industrial waste water treatment plant as inoculum. The pH, redox potential, and sulfate and sulfide concentrations were measured twice a week over a maximum of 171 days. The microbial communities in the bioreactors were characterized by qPCR and high throughput amplicon sequencing. The pH in the bioreactors fluctuated between 5.0 and 7.7 with the highest amount of up to 50% sulfate removed measured around pH 6. Dissimilatory sulfate reducing bacteria (SRB constituted only between 1% and 15% of the bacterial communities. Predicted bacterial metagenomes indicated a high prevalence of assimilatory sulfate reduction proceeding to formation of l-cystein and acetate, assimilatory and dissimilatory nitrate reduction, denitrification, and oxidation of ethanol to acetaldehyde with further conversion to ethanolamine, but not to acetate. Despite efforts to maintain optimal conditions for biological sulfate reduction in the bioreactors, only a small part of the microorganisms were SRB. The microbial communities were highly diverse, containing bacteria, archaea, and fungi, all of which affected the overall microbial processes in the bioreactors. While it is important to monitor specific physicochemical parameters in bioreactors, molecular assessment of the microbial communities may serve as a tool to identify biological factors affecting bioreactor functions and to optimize physicochemical attributes for ideal bioreactor performance.

    Full Text Available Gastrointestinal bleeding (GIB is determined in 20-30% of patients with peptic ulcer disease. Acute gastrointestinal bleeding is on the first place as the main cause of deaths from peptic ulcer ahead of the other complications. Rebleeding occurs in 30-38% of patients. Materials and Methods For getting of the objective endoscopic picture in patients with bleeding gastroduodenal ulcers we used the classification of J.A. Forrest in our study: Type I - active bleeding: • I a - pulsating jet; • I b - stream. Type II - signs of recent bleeding: • II a - visible (non-bleeding visible vessel; • II b - fixed thrombus - a clot; • II c - flat black spot (black bottom ulcers. Type III - ulcer with a clean (white down. Integrated endoscopic hemostasis included: irrigation of ulcer defect and area around it with 3% hydrogen peroxide solution in a volume of 10 - 30ml; Injection of 2-4 mL of diluted epinephrine (1:10000 for hemostasis; use of Argon plasma coagulation. Results and Discussion Integrated endoscopic stop of bleeding was performed in 57 patients who were examined and treated at the Department of Surgery from 2006 to 2012. In 16 patients bleeding was caused by gastric ulcer. Gastric ulcer type I localization according to classification (HD Johnson, 1965 was determined in 9 patients, type II - in 2 patients, type III – in 5 patients. In 31 patients bleeding was caused by duodenal peptic ulcer, in 4 patients - erosive gastritis, 1 - erosive esophagitis, and in 5 patients - gastroenteroanastomosis area peptic ulcer. Final hemostasis was achieved in 55 (96.5% patients. In 50 (87.7% patients it was sufficient to conduct a single session of complex endoscopic treatment. In 5 (8.8% patients – it was done two times. In 2 (3.5% cases operation was performed due to the recurrent bleeding. The source of major bleeding in these patients was: chronic, duodenal ulcer penetrating into the head of the pancreas in one case complicated by subcompensated

    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. All patients fully recovered. Conclusion: sclerotherapy with 96% ethanol for venous malformations was found to be effective for symptomatic improvement, but serious complications can occur.

    2015-10-01

    To describe outcomes for dogs with primary hyperparathyroidism following treatment with percutaneous ultrasound-guided ethanol ablation of presumed functional parathyroid nodules. Retrospective case series. 24 dogs with primary hyperparathyroidism that underwent 27 ultrasound-guided ethanol ablation procedures of presumed functional parathyroid nodules identified by cervical ultrasonography. Dogs were anesthetized for each procedure. For each nodule, 95% ethanol was injected into the center with ultrasound guidance (volume injected calculated on the basis of ultrasonographic measurements). The interval from treatment to resolution of hypercalcemia, complications, and follow-up clinicopathologic data were recorded. 5 procedures involved simultaneous treatment of 2 nodules. Three dogs underwent a second treatment because of initial treatment failure or development of another nodule. Hypercalcemia resolved after 23 of 27 (85%) procedures. In those 23 treatments, 22 (96%) had resolution of hypercalcemia within 72 hours after treatment. Hypocalcemia was detected in 6 different dogs at 2 (1 dog), 7 (3 dogs), 14 (1 dog), and 21 (1 dog) days after treatment; 5 of these dogs had mild transient hypocalcemia and 1 developed clinical signs requiring calcium supplementation. Although there were no periprocedural adverse effects, 2 dogs had delayed adverse effects; the overall rate of complications (including delayed adverse events and clinical hypocalcemia) was 11.1%. Long-term follow-up data indicated sustained normocalcemia in 17 of 19 dogs. Results suggested that percutaneous ultrasound-guided ethanol ablation of functional parathyroid nodules may be an effective treatment for primary hyperparathyroidism of dogs, with short duration of anesthesia, minimal complications, and low risk for hypocalcemia.

    1985-03-01

    Ethanol was administered to rats by means of a liquid diet for 16 days; after an ethanol-free interval of four weeks, animals received a test (IP) dose of ethanol (2 g/kg), and the adrenocortical and adrenomedullary responses were evaluated. Chronically ethanol-exposed animals showed tolerance to the stimulatory effect of ethanol in the pituitary-adrenal axis. Likewise, previously dependent rats showed tolerance to the increase in the activity of the adrenomedullary function induced by acute administration of the drug. Our results indicate that chronic ethanol ingestion can induce persistent changes after complete alcohol abstinence.

    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

    Alcohol-based hand sanitizers (ABHSs) have been widely used in homes, workplaces and schools to prevent the spread of infectious diseases. We report a young child unintentionally ingested ABHS at a school, resulting in intoxication. The child was a 6-year-old girl who had been brought to the emergency department (ED) for hypothermia, altered mental status (AMS), periods of hypoventilation, hypothermia and vomiting. Computed tomography of her head revealed nothing abnormal in intracranial pathology. Urine drug screening was negative. Alcohol level was 205 mg/dL on admission. Other abnormal values included potassium of 2.8 mEq/L, osmolality of 340 mOsm/kg and no hypoglycemia. Further investigation revealed that the patient had gone frequently to the class restroom for ingestion of unknown quantities of ABHSs during the day. The patient was admitted for one day for intravenous fluid hydration and close observation of her mental status. The patient was discharged from the hospital the next day without any complications. Despite the large safety margin of ABHSs, emergency physicians need to be aware of the potential risk of ingestion of a large amount of such products in children and consider it in the assessment and management of school-age children with acute AMS.

    Purpose: Topotecan (TPT), a camptothecin analog, is currently used to treat human ovarian and small-cell lung cancer and is in clinical trials for other tumor sites. However, it is unknown whether chronomodulation of TPT treatment is beneficial. We examined the effects of administering TPT or X-radiation (XR) alone at different times of the day or night. Methods: We treated mice bearing human colorectal tumor xenografts at four different times representing the early rest period (9 AM or 3 HALO [hours after light onset]), late rest period (3 PM or 9 HALO), early active period (9 PM or 15 HALO), and late active period (3 AM or 21 HALO) of the mice. We gave either TPT (12 mg/kg, injected i.p.) or XR (4 Gy, directed to the tumor) twice weekly on Days 0, 4, 7, 10 within 2 weeks. Results: Treatment with either TPT or XR at 3 AM demonstrated the greatest efficacy (measured by a tumor regrowth assay) without significantly increasing acute toxicity (assessed by a decrease in leukocyte counts or body weight). Conversely, treatment at 3 PM, in particular, showed increased toxicity without any enhanced efficacy. Conclusions: Our study provided the first evidence that chronomodulation of TPT treatments, consistent with the findings of other camptothecin analogs, is potentially clinically beneficial. Additionally, our findings suggest that chronomodulation of fractionated XR treatments is also potentially clinically beneficial

    Alcohol abuse and alcoholism remain one of the major health issues worldwide, especially in developing countries. The protective effect of Phellinus rimosus against acute alcohol-induced lipid peroxidation in the liver, kidney, and brain as well as its effect against antioxidant enzyme activity such as superoxide (SOD) and catalase (CAT) in the liver was evaluated in mice. Ethyl acetate extract of Ph. Rimosus (50 mg/kg body wt, p.o.) 1 h before each administration of alcohol (3 mL/kg, p.o.; total 2 doses at 24-h intervals) protected against lipid peroxidation in all organs and attenuated the decline of SOD and CAT activity in the liver. The fold increase in lipid peroxidation, including conjugated diene and thiobarbituric acid reactive substance (TBARS) levels, was highest in the liver. There were 2.6- and 1.5- fold increases in TBARS levels in the liver of the alcohol alone- and alcohol+Ph. Rimosus-treated groups, compared with that of the normal group. Activity of SOD and CAT in the liver of alcohol- and alcohol+Ph. Rimosus- treated animals was 9.05±1.38, 18.76±1.71, and 11.26±1.02, 31.58±3.35 IU/mg protein, respectively. Extract at 1 mg/mL inhibited 50.6% activity of aniline hydroxylase (CYP2E1) in liver homogenate. From these results, we concluded that the extract significantly protected against the lipid peroxidation. Protection in the liver may be due to the inhibitory effect on CYP2E1 as well as the direct radical scavenging effect of Ph. Rimosus, which warrants further research.

    Objective: To evaluate CT-guided percutaneous ethanol nerve block therapy of celiac plexus embedded in metastatic lymph nodes in treating intractable carcinomatous abdominal pain. Methods: A total of 104 patients with late stage cancers were enrolled in this study. All patients suffered from serious carcinomatous pain at upper abdomen and their retroperitoneal lymph nodes were extensively enlarged and fused, together with the involved celiac plexus, into a hard crumb. As the patients failed to respond to narcotic analgesics CT-guided ethanol nerve block therapy of celiac plexus was carried out by pushing the puncture needle through the fused lymphatic mass to celiac plexus site. The analgesic effects and complications were observed and the therapeutic results were evaluated. Results: The analgesic effective rate of ethanol nerve block therapy immediately after the procedure was 100%, and at 2 weeks, 1, 2, 3 and 4 months after the treatment it was 100%, 100%, 98.0%, 96.9% and 92.6%, respectively. No serious complications occurred during perioperative period. The living quality was markedly improved in all patients. Conclusion: For the treatment of intractable carcinomatous abdominal pain in patients with their celiac plexus being embedded in mass-like metastatic retroperitoneal lymph nodes CT-guided percutaneous ethanol nerve block therapy by pushing the puncture needle through the fused lymphatic mass to celiac plexus site is of great clinical value in relieving carcinomatous abdominal pain.

    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.

    Full Text Available Purpose. Percutaneous cholecystostomy (PC has increasingly been used as bridge to surgery as well as sole treatment for patients with acute cholecystitis (AC. The aim of the study was to assess the outcome after PC compared to acute cholecystectomy in patients with AC. Methods. A review of medical records was performed on all patients residing in Stockholm County treated for AC in the years 2003 and 2008. Results. In 2003 and 2008 altogether 799 and 833 patients were admitted for AC. The number of patients treated with PC was 21/799 (2.6% in 2003 and 50/833 (6.0% in 2008. The complication rate (Clavien-Dindo ≥ 2 was 4/71 (5.6% after PC and 135/736 (18.3% after acute cholecystectomy. Mean (standard deviation hospital stay was 11.4 (10.5 days for patients treated with PC and 5.1 (4.3 days for patients undergoing acute cholecystectomy. After adjusting for age, gender, Charlson comorbidity index, and degree of cholecystitis, the hospital stay was significantly longer for patients treated with PC than for those undergoing acute cholecystectomy (P<0.001 but the risk for intervention-related complications was found to be significantly lower (P=0.001 in the PC group. Conclusion. PC can be performed with few serious complications, albeit with a longer hospital stay.

    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 [ 14 C]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 [ 14 C]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, [ 14 C]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

    Disseminated cryptococcal infection is rarely reported in the setting of pediatric acute leukemia, despite the immunocompromised state of these patients. However, when present, disseminated cryptococcal infection poses treatment challenges and is associated with significant morbidity and mortality. Treatment of invasive fungal disease in a child with acute leukemia requires a delicate balance between anti-fungal and anti-neoplastic therapy. This balance is particularly important early in the course of leukemia, since both the underlying disease and overwhelming infection can be life threatening. We describe the successful management of life-threatening disseminated cryptococcosis in a child with acute lymphoblastic leukemia during induction therapy. PMID:22258349

    Local laser therapy has been suggested as a promising treatment for acute hamstring muscle tears. We carried out a shortcut systematic review to establish whether therapeutic lasers are beneficial for patients with acute hamstring tears. Despite a comprehensive literature search, no studies that were directly relevant to the question could be identified. The clinical bottom line is therefore that there is currently no evidence for the use of any form of laser therapy in the treatment of acute hamstring muscle tears. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  10. Acute ethanol has biphasic effects on short- and long-term memory in both foreground and background contextual fear conditioning in C57BL/6 mice.

    Gulick, Danielle; Gould, Thomas J

    2007-09-01

    Ethanol is a frequently abused, addictive drug that impairs cognitive function. Ethanol may disrupt cognitive processes by altering attention, short-term memory, and/or long-term memory. Interestingly, some research suggests that ethanol may enhance cognitive processes at lower doses. The current research examined the dose-dependent effects of ethanol on contextual and cued fear conditioning. In addition, the present studies assessed the importance of stimulus salience in the effects of ethanol and directly compared the effects of ethanol on short-term and long-term memory. This study employed both foreground and background fear conditioning, which differ in the salience of contextual stimuli, and tested conditioning at 4 hours, 24 hours, and 1 week in order to assess the effects of ethanol on short-term and long-term memory. Foreground conditioning consisted of 2 presentations of a foot shock unconditioned stimulus (US) (2 seconds, 0.57 mA). Background conditioning consisted of 2 auditory conditioned stimulus (30 seconds, 85 dB white noise)-foot shock (US; 2 seconds, 0.57 mA) pairings. For both foreground and background conditioning, ethanol enhanced short-term and long-term memory for contextual and cued conditioning at a low dose (0.25 g/kg) and impaired short-term and long-term memory for contextual and cued conditioning at a high dose (1.0 g/kg). These results suggest that ethanol has long-lasting, biphasic effects on short-term and long-term memory for contextual and cued conditioning. Furthermore, the effects of ethanol on contextual fear conditioning are independent of the salience of the context.

    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

    2011-01-01

    Anaerobic digestion of vinasse derived from bioethanol manufacturing, in which total COD was found to be 68.56 ± 8.17 g/L, was studied in batch laboratory-scale reactors at mesophilic temperature (35 deg. C). The vinasse was subjected to a short ozonation pre-treatment (15 min) in which more than 50% reduction of phenols was observed, although the total organic carbon concentration remained approximately stable, indicating that the phenols were transformed into other simpler forms. The anaerobic biodegradability of raw and pre-treated vinasse was similar, reaching values close to 80% (COD). However, the methane yield coefficient and methane production rate enhanced by around 13.6% and 41.16%, respectively, when the ozonized vinasse was fed. These results indicate that the integration of chemical-biological treatments could be a viable option for the purification of this hazardous wastewater.

    To test the hypothesis that ineffective acute treatment of episodic migraine (EM) is associated with an increased risk for the subsequent onset of chronic migraine (CM). In the American Migraine Prevalence and Prevention Study, respondents with EM in 2006 who completed the Migraine Treatment Optimization Questionnaire (mTOQ-4) and provided outcome data in 2007 were eligible for analyses. The mTOQ-4 is a validated questionnaire that assesses treatment efficacy based on 4 aspects of response to acute treatment. Total mTOQ-4 scores were used to define categories of acute treatment response: very poor, poor, moderate, and maximum treatment efficacy. Logistic regression models were used to examine the dichotomous outcome of transition from EM in 2006 to CM in 2007 as a function of mTOQ-4 category, adjusting for covariates. Among 5,681 eligible study respondents with EM in 2006, 3.1% progressed to CM in 2007. Only 1.9% of the group with maximum treatment efficacy developed CM. Rates of new-onset CM increased in the moderate treatment efficacy (2.7%), poor treatment efficacy (4.4%), and very poor treatment efficacy (6.8%) groups. In the fully adjusted model, the very poor treatment efficacy group had a more than 2-fold increased risk of new-onset CM (odds ratio = 2.55, 95% confidence interval 1.42-4.61) compared to the maximum treatment efficacy group. Inadequate acute treatment efficacy was associated with an increased risk of new-onset CM over the course of 1 year. Improving acute treatment outcomes might prevent new-onset CM, although reverse causality cannot be excluded. © 2015 American Academy of Neurology.

    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.

    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

    Mixed-phenotype acute leukemia (MPAL) is a heterogeneous group of hematopoietic malignancies in which blasts show markers of multiple developmental lineages and cannot be clearly classified as acute myeloid or lymphoblastic leukemias. Historically, various names and classifications were used for this rare entity accounting for 2-5% of all acute leukemias depending on the diagnostic criterias used. The currently valid classification of myeloid neoplasms and acute leukemia published by the World Health Organization (WHO) in 2016 refers to this group of diseases as MPAL. Because adverse cytogenetic abnormalities are frequently present, MPAL is generally considered a disease with a poor prognosis. Knowledge of its treatment is limited to retrospective analyses of small patient cohorts. So far, no treatment recommendations verified by prospective studies have been published. The reported data suggest that induction therapy for acute lymphoblastic leukemia followed by allogeneic hematopoietic cell transplantation is more effective than induction therapy for acute myeloid leukemia or consolidation chemotherapy. The establishment of cooperative groups and international registries based on the recent WHO criterias are required to ensure further progress in understanding and treatment of MPAL. This review summarizes current knowledge on the diagnosis, classification, prognosis and treatment of MPAL patients.

    In the present study, we assess maternal depressive symptoms at the beginning and end of treatment to investigate the possible reciprocal relationship of maternal illness with the child's depressive illness and treatment. We present data on 146 children and their mothers who were participating in a pediatric acute treatment study of fluoxetine. Patients were assessed with the Children's Depression Rating Scale-Revised at baseline and at each treatment visit. Mothers completed the Quick Inventory of Depressive Symptomatology-Self Report at baseline and end of acute treatment. Thirty percent of mothers had moderate to severe levels of depressive symptoms at the child's baseline assessment. Overall, mothers reported improvement in maternal depressive symptoms at the end of their child's acute treatment, although maternal depression was not specifically targeted for intervention. Furthermore, mother's depressive symptoms appear to be associated with the child's depression severity both at the beginning and end of treatment. Mothers with higher levels of depressive symptoms had children with higher levels of depression severity at baseline and over the course of treatment. However, maternal depressive symptoms at baseline had no association with the rate of improvement of child depression severity. This study indicates a positive relationship between the depression severity of mothers and their children. These findings highlight potential areas of intervention in the acute treatment of childhood depression.

    Full Text Available Abstract Background Replacing the energy-intensive evaporation of stillage by anaerobic digestion is one way of decreasing the energy demand of the lignocellulosic biomass to the ethanol process. The biogas can be upgraded and sold as transportation fuel, injected directly into the gas grid or be incinerated on-site for combined heat and power generation. A techno-economic evaluation of the spruce-to-ethanol process, based on SO2-catalysed steam pretreatment followed by simultaneous saccharification and fermentation, has been performed using the commercial flow-sheeting program Aspen Plus™. Various process configurations of anaerobic digestion of the stillage, with different combinations of co-products, have been evaluated in terms of energy efficiency and ethanol production cost versus the reference case of evaporation. Results Anaerobic digestion of the stillage showed a significantly higher overall energy efficiency (87-92%, based on the lower heating values, than the reference case (81%. Although the amount of ethanol produced was the same in all scenarios, the production cost varied between 4.00 and 5.27 Swedish kronor per litre (0.38-0.50 euro/L, including the reference case. Conclusions Higher energy efficiency options did not necessarily result in lower ethanol production costs. Anaerobic digestion of the stillage with biogas upgrading was demonstrated to be a favourable option for both energy efficiency and ethanol production cost. The difference in the production cost of ethanol between using the whole stillage or only the liquid fraction in anaerobic digestion was negligible for the combination of co-products including upgraded biogas, electricity and district heat.

    In Germany there is a clear deficit in the non-operative treatment of chronic and complex diseases and pain disorders in acute care hospitals. Only about 20 % of the treatments are carried out in orthopedic hospitals. Hospitals specialized in manual medicine have therefore formed a working group on non-operative orthopedic manual medicine acute care clinics (ANOA). The ANOA has developed a multimodal assessment procedure called the OPS 8-977 which describes the structure and process quality of multimodal and interdisciplinary diagnosis and treatment of the musculoskeletal system. Patients are treated according to clinical pathways oriented on the clinical findings. The increased duration of treatment in the German diagnosis-related groups (DRG) system is compensated for with a supplemental remuneration. Thus, complex and multifactorial orthopedic diseases and pain disorders are conservatively and appropriately treated as inpatient departments of acute care hospitals.

    Ethanol abuse can lead to negative consequences that oftentimes result in criminal charges and civil lawsuits. When an individual is suspected of driving under the influence, law enforcement agents can determine the extent of intoxication by measuring the blood alcohol concentration (BAC) and performing a standardized field sobriety test. The BAC is dependent on rates of absorption, distribution, and elimination, which are influenced mostly by the dose of ethanol ingested and rate of consumption. Other factors contributing to BAC are gender, body mass and composition, food effects, type of alcohol, and chronic alcohol exposure. Because of individual variability in ethanol pharmacology and toxicology, careful extrapolation and interpretation of the BAC is needed, to justify an arrest and assignment of criminal liability. This review provides a summary of the pharmacokinetic properties of ethanol and the clinical effects of acute intoxication as they relate to common forensic questions. Concerns regarding the extrapolation of BAC and the implications of impaired memory caused by alcohol-induced blackouts are discussed. © 2017 American Academy of Psychiatry and the Law.

    Early definitive treatment (cholecystectomy or endoscopic sphincterotomy in the same admission or within 2 weeks after discharge) of gallstone disease after a biliary attack of acute pancreatitis is standard of care. This study investigated whether compliance with early definitive treatment for acute gallstone pancreatitis can be used as a care quality indicator for the condition. A retrospective cohort study was conducted using the Hospital Episode Statistics database. All emergency admissions to National Health Service hospitals in England with a first time diagnosis of acute gallstone pancreatitis in the financial years 2008, 2009 and 2010 were examined. Trends in early definitive treatment between hospital trusts were examined and patient morbidity outcomes were determined. During the study interval there were 19 510 patients with an overall rate of early definitive treatment at 34·7 (range 9·4-84·7) per cent. In the 1-year follow-up period, 4661 patients (23·9 per cent) had one or more emergency readmissions for complications related to gallstone pancreatitis. Of these, 2692 (57·8 per cent) were readmissions for acute pancreatitis; 911 (33·8 per cent) were within the first 2 weeks of discharge, with the remaining 1781 (66·2 per cent) occurring after the point at which definitive treatment should have been received. Early definitive treatment resulted in a 39 per cent reduction in readmission risk (adjusted risk ratio (RR) 0·61, 95 per cent c.i. 0·58 to 0·65). The risk was further reduced for acute pancreatitis readmissions to 54 per cent in the early definitive treatment group (adjusted RR 0·46, 0·42 to 0·51). In acute gallstone pancreatitis, compliance with recommended early definitive treatment varied considerably, with associated variation in outcomes. Compliance should be used as a quality indicator to improve care. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Despite advancements in modern medicine, the treatment of acute heart failure (AHF) after acute myocardial infarction (AMI) remains challenging. Milrinone is effective in the treatment of chronic congestive heart failure, but its safety and efficacy in patients with AHF after AMI have not been systematically evaluated. This meta-analysis was performed to assess the safety and efficacy of milrinone in patients with AHF after AMI. We used a pre-designed protocol to search electronic databases for randomized trials assessing milrinone for the treatment of AHF after AMI. Data were abstracted from relevant studies. Heterogeneity was assessed qualitatively using a Q test and quantified using the I(2) statistic. Pooled risk estimates with 95% confidence intervals (CIs) were obtained using fixed-effects models unless substantial heterogeneity was observed (I(2) ≥ 50% and heterogeneity p ≤ 0.1). Four randomized trials met the inclusion criteria. However, there were no significant differences in deaths, blood pressure, premature ventricular contractions, gastrointestinal reactions, or ventricular tachycardia or fibrillation (all p > 0.05) between control group and milrinone treatment group. Pooled estimates showed that milrinone significantly increased the left ventricular ejection fraction (MD 5.69; 95% CI 4.27 to 7.10; p milrinone may be safe and effective for patients with AHF after AMI. However, this meta-analysis did not show that milrinone could improve prognosis or the survival rate. © 2015 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    Despite the high morbidity and mortality associated with bipolar depression, the optimal treatment for this phase is still a matter of debate. The aim of the current review was to provide updated evidence about the efficacy and tolerability of anticonvulsants in the treatment of acute bipolar depression. A comprehensive review of randomized controlled trials (RCTs) evaluating the use of anticonvulsants for the treatment of acute bipolar depression up to June 2011 was conducted by means of the PubMed-Medline database. Eligibility criteria included active comparator-controlled or placebo-controlled randomized studies involving monotherapy or combination therapy. A total of 18 RCTs fulfilled the inclusion criteria. Studies supported the efficacy of divalproex as monotherapy in acute bipolar depression but small sample size was a common methodological limitation. Findings were inconclusive for lamotrigine and carbamazepine although overall lamotrigine may have a beneficial but modest effect. Negative results were found for levetiracetam and gabapentin but the evidence base on these agents is scant. All anticonvulsants were generally well tolerated. No double-blind RCTs were found for the use of other anticonvulsants such as oxcarbazepine, licarbazepine, zonisamide, retigabine, pregabalin, tiagabine, felbamate and vigabatrine in the acute treatment of bipolar depression. To sum up, taking into consideration the efficacy and tolerability profiles of anticonvulsants, current evidence supports the use of divalproex and lamotrigine in the treatment of acute bipolar depression. However, available data for most other anticonvulsants are inconclusive and further RCTs with larger sample sizes are needed before drawing firm conclusions.

    Children with cystic fibrosis often experience acute declines in lung function. We previously showed that such declines are not always treated with antibiotics, but we did not assess whether treatment improves the likelihood of recovery. To determine whether new antibiotic treatment was associated with recovery from acute FEV 1 decline. We studied episodes of FEV 1 decline (≥10% from baseline) in the Epidemiologic Study of Cystic Fibrosis. Treatments were hospitalization, home intravenous antibiotic, new inhaled oral quinolone, or other oral antibiotic. We used logistic regression to evaluate whether treatment was associated with recovery to baseline or near baseline. Logistic regression of 9,875 patients showed that new antibiotic treatment was associated with an increased likelihood of recovery to 90% of baseline (P antibiotic (odds ratio [OR], 2.79; 95% confidence interval, 2.41-3.23). All four outpatient treatments were associated with greater likelihood of recovery compared with no treatment (OR, 1.27-1.64). Inpatient treatment was better than outpatient treatment (OR, 1.94; 95% confidence interval, 1.68-2.23). Treatment-type ORs were similar across recovery criteria and levels of baseline lung function. New antibiotic therapy, and especially inpatient treatment, is associated with greater likelihood of recovery after acute decline in FEV 1 . Benefits extend across all disease stages and are especially important in patients with high lung function, who are at greatest risk for FEV 1 decline.

    To examine the combined hepatoxic and nephrotoxic effects of cadmium and ethanol, rats maintained on an ethanol containing liquid diet (5% w/w) were given cadmium either acutely (3 x 1 mg/kg IP) or subacutely (about 14 mg/kg/day PO for 6 weeks). Parameters tested were cadmium, zinc and copper contents of blood and various organs, metallothionein (MT) contents, polysome profile of liver and kidneys, serum SDH and GPT levels and creatinine clearnace. Ethanol reduced the hepatic MT contents without altering the polysome profile and the zinc and copper contents. Cadmium on the other hand raised the MT contents in liver and kidneys. This effect of cadmium predominated in the combined treatment. Morphological examination and functional tests (SDH, GPT, creatinine clearance) indicate that cadmium does not enhance the toxic effects of ethanol, and vice versa. (orig.).

    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 workers 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 oxygenation without use of expensive, invasive and experimental procedures. Prone positioning is a safe and effective way to improve ventilation when conventional strategies fail to initiate a patient response. Because a specific cure for ARDS is not available, the goal is to support the patients with therapies that cause the least amount of injury while the lungs have an opportunity to heal. Based on current data, a trial of prone positioning ventilation should be offered to the patients who have ALI/ARDS in the early course of the disease. Published studies exhibit substantial heterogeneity in clinical results, suggesting that an adequately sized study optimizing the duration of proning ventilation strategy is warranted to enable definitive conclusions to be drawn.

    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. Copyright © 2011 Elsevier Ltd.

    Full Text Available Animal studies and premarketing clinical trials have revealed hepatotoxicity of statins, primarily minor elevations in serum alanine aminotransferase levels. The combined chronic use of medicines and eventual ethanol abuse are common and may present a synergistic action regarding liver injury. Our objective was to study the effect of the chronic use of atorvastatin associated with acute ethanol administration on the liver in a rat model. One group of rats was treated daily for 5 days a week for 2 months with 0.8 mg/kg atorvastatin by gavage. At the end of the treatment the livers were perfused with 72 mM ethanol for 60 min. Control groups (at least 4 animals in each group consisted of a group of 2-month-old male Wistar EPM-1 rats exposed to 10% ethanol (v/v ad libitum replacing water for 2 months, followed by perfusion of the liver with 61 nM atorvastatin for 60 min, and a group of animals without chronic ethanol treatment whose livers were perfused with atorvastatin and/or ethanol. The combination of atorvastatin with ethanol did not increase the release of injury marker enzymes (alanine aminotransferase, aspartate aminotransferase, and lactic dehydrogenase from the liver and no change in liver function markers (bromosulfophthalein clearance, and oxygen consumption was observed. Our results suggest that the combination of atorvastatin with ethanol is not more hepatotoxic than the separate use of each substance.

    Young adults with acute lymphoblastic leukemia are a distinctive category of patients, with substantial difference in disease biology and response to therapy; hence, they pose unique challenges and issues beyond those faced by children and older adults. Despite inferior survival compared to children, there is growing evidence to suggest that young adults have improved outcomes when treated with pediatric-based approaches. With better supportive care and toxicity management and multidisciplinary team and approach, we have made great improvement in outcomes of young adults with ALL. However, despite significant progress, patients with persistence of minimal residual disease have a poor prognosis. This review discusses current controversies in the management of young adults with ALL, outcomes following pediatric and adult protocols, and the role of allogeneic stem cell transplantation. We also explore recent advances in disease monitoring and highlight our approach to incorporation of novel therapies in the management of young adults with ALL.

    Occupational standard of the Ministry of health-Application Standards of Hematopoietic Stimulating Factors in the Treatment of Acute Radiation Sickness has been completed as a draft standard. Based on the wide study and analysis of related animal experimental literature about hematopoietic stimulating factor in the treatment of acute radiation sickness and domestic and foreign clinical reports about application of hematopoietic stimulating factor in radiation accidents in the past decade, the standard was enacted according to the suggestions of International Atomic Energy Agency and the United States Strategic National Stockpile Radiation Working Group and European countries about the application of hematopoietic stimulating factor. It is mainly used for nuclear accident emergency and the treatment of the bone marrow form of acute radiation sickness caused by radiation accidents. It also applies to other hematopoietic failure diseases. In order to implement this standard correctly, the relevant contents of the standard were interpreted in this article. (authors)

    Full Text Available Objective: To investigate the in vitro antioxidant activity of ethanolic extract of Artocarpus heterophyllus (A. heterophyllus stem bark and its inhibitory effect on a-amylase and a-glucosidase. Methods: The A. heterophyllus stem bark was extracted using methanol and tested for antioxidative activity. Results: The results revealed that the ethanolic extract has polyphenolics and free radical scavenging compounds which were significantly higher (P < 0.05 than their respective standard, at concentration dependent manner. The ethanolic extract of A. heterophyllus stem bark was observed to show inhibitory activities on a-amylase and a-glucosidase with IC50 of (4.18 ± 0.01 and (3.53 ± 0.03 mg/mL, respectively. The Lineweaver-Burk plot revealed that ethanolic extract of A. heterophyllus stem bark exhibited non-competitive inhibition for a-amylase and uncompetitive inhibition for a-glucosidase activities. Also, gas chromatography–mass spectrometry showed the presence of different bioactive compounds in extract. Conclusions: Therefore, it can be inferred from this study that ethanolic extract of A. heterophyllus stem bark may be useful in the management of diabetes mellitus probably due to bioactive compounds observed in the extract.

  15. Trends in antibiotic treatment of acute otitis media and treatment failure in children, 2000-2011.

    Full Text Available 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.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.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%.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.

    2016-04-01

    People who suffer from headaches often prefer nutraceutical treatment over traditional pharmacological approaches, due to fear of possible side effects, drug dependence, or addiction. Since treatment with nutraceuticals does not require a doctor's prescription, many patients rely on their own judgment as to when and which one to take, often without consultation or guidance from their physician. Some physicians could provide information about potential efficacy and side effects of various products, but many are not familiar with the nutraceuticals. Widespread skepticism persists among doctors about the effectiveness of these treatments. This is largely due to the lack of rigorous clinical studies. However, even when incontrovertible scientific evidence exists, many physicians remain distrustful of the evidence. The following review summarizes randomized controlled trials of some of the most commonly used non-pharmacological treatments, including magnesium, coenzyme Q10, riboflavin (vitamin B2), petasites, and feverfew (Table 1).

    Full Text Available Acute pyelonephritis is a serious infection in pregnancy. It is presented with fever, shaking chills and flank pain. Intravenous hydration and antimicrobial therapy are sufficient in the treatment unless pyelonephritis is complicated. In case of fever persisting for more than 48 h despite appropriate antimicrobial treatment, a possible complication such as urinary tract obstruction, abscess or phlegmon should be considered. Here, we present an 18-year-old pregnant woman with acute pyelonephritis whose persistent fever returned to normal after double-J ureteral stent was placed even if she had no finding of such a complication.

    A significant percentage of patients with pancreatitis often presents a history of excessive alcohol consumption. Nevertheless, the patho-physiological effect of ethanol on pancreatitis remains poorly understood. In the present study, we have investigated the early effects of acute ethanol exposure on CCK-8-evoked Ca2+ signals in mouse pancreatic acinar cells. Changes in [Ca2+]i and ROS production were analyzed employing fluorescence techniques after loading cells with fura-2 or CM-H2DCFDA, respectively. Ethanol, in the concentration range from 1 to 50 mM, evoked an oscillatory pattern in [Ca2+]i. In addition, ethanol evoked reactive oxygen species generation (ROS) production. Stimulation of cells with 1 nM or 20 pM CCK-8, respectively led to a transient change and oscillations in [Ca2+]i. In the presence of ethanol a transformation of 20 pM CCK-8-evoked physiological oscillations into a single transient increase in [Ca2+]i in the majority of cells was observed. Whereas, in response to 1 nM CCK-8, the total Ca2+ mobilization was significantly increased by ethanol pre-treatment. Preincubation of cells with 1 mM 4-MP, an inhibitor of alcohol dehydrogenase, or 10 microM of the antioxidant cinnamtannin B-1, reverted the effect of ethanol on total Ca2+ mobilization evoked by 1 nM CCK-8. Cinnamtannin B-1 blocked ethanol-evoked ROS production. ethanol may lead, either directly or through ROS generation, to an over stimulation of pancreatic acinar cells in response to CCK-8, resulting in a higher Ca2+ mobilization compared to normal conditions. The actions of ethanol on CCK-8-stimulation of cells create a situation potentially leading to Ca2+ overload, which is a common pathological precursor that mediates pancreatitis.

    Diverticular disease of the colon is a common disorder, characterized by recurrent symptoms and complications such as diverticulitis, requiring hospital admissions and surgery. This study aimed to systematically review the evidence for medical therapy of diverticular disease in reducing symptoms and preventing acute diverticulitis. MEDLINE and Embase databases (1966 to February 2010). The studies selected were prospective clinical trials on uncomplicated diverticular disease of the colon. Four investigators independently reviewed articles, extracted data, and assessed study quality according to standardized criteria. The main outcomes measured were improvement in symptoms, complete remission of symptoms, and prevention of acute diverticulitis. We identified 31 studies, including 6 placebo-controlled trials. The methodological quality of these studies was suboptimal. Only 10 trials provided a detailed description of the patient history, 8 assessed symptoms by the use of a validated questionnaire, and 14 appropriately defined inclusion and exclusion criteria. Only one long-term double-blind placebo-controlled study was identified. This reported a significant improvement in symptoms and greater prevalence of symptom-free patients at 1 year with fiber plus rifaximin in comparison with fiber alone. The efficacy of treatment in preventing acute diverticulitis was evaluated in 11 randomized trials. Four trials compared rifaximin plus fiber vs fiber alone and failed to show a significant difference between treatments. However, cumulative data from these trials revealed a significant benefit following rifaximin and fiber (1-year rate of acute diverticulitis: 11/970 (1.1%) vs 20/690 (2.9%); P = .012), but with a number needed to treat of 57, to prevent an attack of acute diverticulitis. : Heterogeneity of the study design, patients' characteristics, regimens and combination of studied treatment, and outcome reporting precluded the pooling of results and limited

    Full Text Available Objective: Acromioclavicular (AC joint dislocation is a common injury frequently affecting young athletes. The aim of this study is to evaluate postoperative functional results in cases diagnosed with acute AC joint dislocation stabilized with endobutton system. Methods: This fixation procedure has been applied on 10 patients. Indications of the technique included: a grade V AC joint dislocation (7 patients, and grade III AC joint dislocation (3 patient according to Rockwood classification. The coracoclavicular (CC interval and AC joint were reduced using two endobuttons. One endobutton was fitted on the clavicle and the second was placed at the undersurface of the coracoid. Outcomes were assessed with the Constant shoulder score and visual analog pain scale. Results: All the patients had powerful intraoperative fixation. Immediately after surgery, and 6 weeks, and 1 year postoperative radiographs showed adequate reduction of the CC distance and the AC joint. The mean Constant shoulder score was 89 (88–92 in the injured shoulder and 90 (88–93 in the uninjured shoulder. There was no statically significant difference between the injured and normal shoulder in terms of Constant shoulder score and there was no complication during the process. Conclusion: This technique is a safe and effective method for providing fixation for the AC joint.

  7. The pharmacokinetics and clinical efficacy of AVP-825: a potential advancement for acute treatment of migraine.

    Cady, Roger

    2015-01-01

    Oral triptans have dominated the prescription market for acute treatment of migraine for nearly 25 years. Today, patients often express dissatisfaction with prescribed acute treatment in part because they do not have confidence that the therapy will provide consistent efficacy over time. Major limitations to sustained successful use of oral triptans are their relatively slow onset of meaningful clinical benefit and variable absorption/efficacy due to impaired gastrointestinal function during migraine. AVP-825, a new intranasal delivery system for sumatriptan , may be an effective alternative to oral triptans. This article reviews AVP-825, which deposits low-dose sumatriptan powder deep into the vascular mucosa of the posterior nose, allowing rapid absorption of drug into the systemic circulation. Studies suggest that AVP-825 is a highly effective, well-tolerated acute treatment for episodic migraine. Oral triptans are limited in providing effective patient-centered outcomes to migraine patients. Failed or suboptimal abortive treatment of migraine is a major driver of migraine chronification and increases in healthcare costs. AVP-825 is an easy to use, novel, breath-powered intranasal delivery system that provides early onset of efficacy with low systemic drug exposure and few triptan-associated adverse events. AVP-825 will be a welcomed therapeutic tool for the acute treatment of migraine.

  8. Topical ganciclovir in the treatment of acute herpetic keratitis.

    2010-08-19

    Herpetic keratitis is caused by herpes simplex virus (HSV) and is a common cause of corneal blindness. Following a primary ocular herpetic infection, latency of the virus occurs, followed by subsequent recurrences of herpetic keratitis. Such recurrences may lead to structural damage of the cornea. Recurrent herpetic keratitis is a common indication for corneal transplantation. Recurrences of herpetic keratitis in the corneal graft may lead to corneal graft rejection. Several antiviral agents for HSV are available, including the thymidine analogs. Prolonged use of thymidine analogs may lead to toxicity of the ocular surface, including epithelial keratitis, corneal ulcers, follicular conjunctivitis, and punctal occlusions. Availability of topical antiviral agents that are safe and effective in the treatment and prophylaxis of herpetic keratitis is highly desirable. Ganciclovir is a potent inhibitor of members of the herpes virus family. The drug has been used systemically for the treatment of cytomegalovirus (CMV) retinitis. Its hematologic toxicity secondary to systemic administration led to its limited use in herpetic infections. On the other hand, topical ganciclovir has been shown to be as safe and effective as acyclovir in the treatment of herpetic epithelial keratitis. Furthermore, topical ganciclovir can reach therapeutic levels in the cornea and aqueous humor following topical application. Several clinical trials have shown that topical ganciclovir 0.15% ophthalmic gel is safe and effective in the treatment and prophylaxis of herpetic epithelial disease. Long-term use of ganciclovir ophthalmic gel in patients with penetrating keratoplasty following herpetic keratitis has prevented recurrences of the disease. Topical ganciclovir ophthalmic gel is well tolerated, does not cause toxic effects on the ocular surface, and does not cause hematologic abnormalities. Clinical studies have underscored the potential role of ganciclovir ophthalmic gel in the treatment and

    The impact of psychosis on the treatment of bipolar depression is remarkably understudied. The primary aim of this study was to compare treatment outcomes of bipolar depressed individuals with and without psychosis. The secondary aim was to compare the effect of lithium and quetiapine, each with adjunctive personalized treatments (APTs), in the psychotic subgroup. We assessed participants with DSM-IV bipolar depression included in a comparative effectiveness study of lithium and quetiapine with APTs (the Bipolar CHOICE study). Severity was assessed by the Bipolar Inventory of Symptoms Scale (BISS) and by the Clinical Global Impression Scale-Severity-Bipolar Version (CGI-S-BP). Mixed models were used to assess the course of symptom change, and Cox regression survival analysis was used to assess the time to remission. Psychotic features were present in 10.6% (n = 32) of the depressed participants (n = 303). Those with psychotic features had higher scores on the BISS before (75.2 ± 17.6 vs. 54.9 ± 16.3; P Bipolar depressive episodes with psychotic features are more severe, and compared to nonpsychotic depressions, present a similar course of improvement. Given the small number of participants presenting psychosis, the lack of statistically significant difference between lithium- and quetiapine-based treatment of psychotic bipolar depressive episodes needs replication in a larger sample. © 2018 Wiley Periodicals, Inc.

    2016-01-01

    The incidence of diverticulosis and diverticular disease of the colon is increasing worldwide. Although the majority of patients remains asymptomatic long-life, the prevalence of diverticular disease of the colon, including acute diverticulitis, is substantial and is becoming a significant burden on National Health Systems in terms of direct and indirect costs. Focus is now being drawn on identifying the correct therapeutic approach by testing various treatments. Fiber, non-absorbable antibiotics and probiotics seem to be effective in treating symptomatic and uncomplicated patients, and 5-aminosalicylic acid might help prevent acute diverticulitis. Unfortunately, robust evidence on the effectiveness of a medical strategy to prevent acute diverticulitis recurrence is still lacking. We herein provide a concise review on the effectiveness and future perspectives of these treatments. PMID:26752946

  15. PATHOGENESIS AND TREATMENT OF THROMBOHEMORRHAGIC DIATHESIS IN ACUTE PROMYELOCYTIC LEUKEMIA

    Directory of Open Access Journals (Sweden)

    Anna Falanga

    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.

  16. Drug Repurposing for the Treatment of Acute Myeloid Leukemia

    Full Text Available Acute myeloid leukemia (AML is a heterogeneous disease characterized by the accumulation of immature myeloid progenitor cells in the bone marrow, compromising of normal blood cell production and ultimately resulting in bone marrow failure. With a 20% overall survival rate at 5 years and 50% in the 18- to 65-year-old age group, new medicines are needed. It is proposed that development of repurposed drugs may be a part of the new therapy needed. AML is subdivided into recurrent molecular entities based on molecular genetics increasingly accessible for precision medicine. Novel therapy developments form a basis for novel multimodality therapy and include liposomal daunorubicin/cytarabine, broad or FLT3-specific tyrosine kinase inhibitors, Bcl-2 family inhibitors, selective inhibitors of nuclear export, metabolic inhibitors, and demethylating agents. The use of non-transplant immunotherapy is in early development in AML with the exceptional re-approval of a toxin-conjugated anti-CD33. However, the full potential of small molecule inhibitors and modalities like immunological checkpoint inhibitors, immunostimulatory small molecules, and CAR-T cell therapy is unknown. Some novel therapeutics will certainly benefit AML patient subgroups; however, due to high cost, more affordable alternatives are needed globally. Also the heterogeneity of AML will likely demand a broader repertoire of therapeutic molecules. Drug repurposing or repositioning represent a source for potential therapeutics with well-known toxicity profiles and reasonable prices. This implies that biomarkers of response need to accompany the development of antileukemic therapies for sharply defined patient subgroups. We will illustrate repurposing in AML with selected examples and discuss some experimental and regulatory limitations that may obstruct this development.

    A key step in informing mental health resource allocation is to identify the predictors of service utilisation and costs. This project aims to identify the predictors of mental health-related acute service utilisation and treatment costs in the year following an acute public psychiatric hospital admission. A dataset containing administrative and routinely measured outcome data for 1 year before and after an acute psychiatric admission for 1757 public mental health patients was analysed. Multivariate regression models were developed to identify patient- and treatment-related predictors of four measures of service utilisation or cost: (a) duration of index admission; and, in the year after discharge from the index admission (b) acute psychiatric inpatient bed-days; (c) emergency department (ED) presentations; and (d) total acute mental health service costs. Split-sample cross-validation was used. A diagnosis of psychosis, problems with living conditions and prior acute psychiatric inpatient bed-days predicted a longer duration of index admission, while prior ED presentations and self-harm predicted a shorter duration. A greater number of acute psychiatric inpatient bed-days in the year post-discharge were predicted by psychosis diagnosis, problems with living conditions and prior acute psychiatric inpatient admissions. The number of future ED presentations was predicted by past ED presentations. For total acute care costs, diagnosis of psychosis was the strongest predictor. Illness acuity and prior acute psychiatric inpatient admission also predicted higher costs, while self-harm predicted lower costs. The development of effective models for predicting acute mental health treatment costs using existing administrative data is an essential step towards a workable activity-based funding model for mental health. Future studies would benefit from the inclusion of a wider range of variables, including ethnicity, clinical complexity, cognition, mental health legal status

    Full Text Available Khalid F Tabbara1,2,3, Noorjehan Al Balushi11The Eye Center and The Eye Foundation for Research in Ophthalmology, Riyadh, 2Department of Ophthalmology, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia; 3The Wilmer Ophthalmological Institute of The Johns Hopkins University School of Medicine, Baltimore, Maryland, USAAbstract: Herpetic keratitis is caused by herpes simplex virus (HSV and is a common cause of corneal blindness. Following a primary ocular herpetic infection, latency of the virus occurs, followed by subsequent recurrences of herpetic keratitis. Such recurrences may lead to structural damage of the cornea. Recurrent herpetic keratitis is a common indication for corneal transplantation. Recurrences of herpetic keratitis in the corneal graft may lead to corneal graft rejection. Several antiviral agents for HSV are available, including the thymidine analogs. Prolonged use of thymidine analogs may lead to toxicity of the ocular surface, including epithelial keratitis, corneal ulcers, follicular conjunctivitis, and punctal occlusions. Availability of topical antiviral agents that are safe and effective in the treatment and prophylaxis of herpetic keratitis is highly desirable. Ganciclovir is a potent inhibitor of members of the herpes virus family. The drug has been used systemically for the treatment of cytomegalovirus (CMV retinitis. Its hematologic toxicity secondary to systemic administration led to its limited use in herpetic infections. On the other hand, topical ganciclovir has been shown to be as safe and effective as acyclovir in the treatment of herpetic epithelial keratitis. Furthermore, topical ganciclovir can reach therapeutic levels in the cornea and aqueous humor following topical application. Several clinical trials have shown that topical ganciclovir 0.15% ophthalmic gel is safe and effective in the treatment and prophylaxis of herpetic epithelial disease. Long-term use of ganciclovir ophthalmic

    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.

    Radiation induced hematopoietic and gastro-intestinal damages in mice were tried to alleviate experimentally by post-treatment. Combined treatment of OK-432 and aztreonam clearly prevented the radiation induced sepsis and elevated the survival rate in mice; the survival was 80% in the OK-432 plus aztreonam group while it was 55% in the group treated with OK-432 alone and 0% with saline. Irsogladine maleate, an anti-ulcer drug, increased the survival rate of jejunal crypt stem cells with a clear dose-related trend. The D 0 for irsogladine maleate was 2.8 Gy although it was 2.3 Gy for saline, These findings suggest that some conventional drugs are effective for radiation induced hematopoietic and gastro-intestinal damages and the possibility that they can be applied for people exposed to radiation accidentally.

    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

    Acute malnutrition affects millions of children each year, yet global coverage of life-saving treatment through the community-based management of acute malnutrition (CMAM) is estimated to be below 15%. We investigated the potential role of stigma as a barrier to accessing CMAM. We surveyed caregivers bringing children to rural health facilities in Marsabit County, Kenya, divided into three strata based on the mid-upper arm circumference of the child: normal status (n = 327), moderate acute malnutrition (MAM, n = 241) and severe acute malnutrition (SAM, n = 143). We used multilevel mixed effects logistic regression to estimate the odds of reporting shame as a barrier to accessing health care. We found that the most common barriers to accessing child health care were those known to be universally problematic: women's time and labour constraints. These constituted the top five most frequently reported barriers regardless of child acute malnutrition status. In contrast, the odds of reporting shame as a barrier were 3.64 (confidence interval: 1.66-8.03, P stigma is an under-recognized barrier to accessing CMAM and may constrain programme coverage. In light of the large gap in coverage of CMAM, there is an urgent need to understand the sources of acute malnutrition-associated stigma and adopt effective means of de-stigmatization. © 2015 John Wiley & Sons Ltd.

    2006-12-01

    A major reason for poor survival of childhood acute lymphoblastic leukemia in developing countries is treatment refusal or abandonment. This can be associated with parental socioeconomic status and attitudes of health care providers. Our study examined the influence of 2 socioeconomic status determinants, parental income and education, on treatment in an Indonesian academic hospital. Medical charts of 164 patients who received a diagnosis of acute lymphoblastic leukemia between 1997 and 2002 were abstracted retrospectively. Data on treatment results and parental financial and educational background were collected. Open interviews were conducted with parents and health care providers. Of all patients, 35% refused or abandoned treatment, 23% experienced treatment-related death, 22% had progressive or relapsed leukemia, and 20% had an overall event-free survival. Treatment results differed significantly between patients with different socioeconomic status; 47% of poor and 2% of prosperous patients refused or abandoned treatment. Although poor and prosperous patients used the same protocol, the provided treatment differed. Poor patients received less individualized attention from oncologists and less structured parental education. Strong social hierarchical structures hindered communication with doctors, resulting in a lack of parental understanding of the necessity to continue treatment. Most poor patients could not afford treatment. Access to donated chemotherapy also was inadequate. Treatment refusal or abandonment frequently resulted. There was no follow-up system to detect and contact dropouts. Health care providers were not fully aware that their own attitude and communication skills were important for ensuring compliance of patients and parents. Children's survival of acute lymphoblastic leukemia in developing countries could improve if problems that are associated with parental financial and educational background and medical teams' attitudes to treatment and

    Nicotine and alcohol adversely affect prostate gland function. In this work, immunohistochemistry was used to investigate the immunoreactivity and distribution of androgen and alpha, beta-oestrogen receptors following chronic treatment with alcohol, nicotine or a combination of both substances, as well as to relate these results to the development of possible prostatic pathologies. Forty male rats were divided into four groups: the Control group received tap water; the Alcoholic group received diluted 10% Gay Lussac ethanol; the Nicotine group received a 0.125 mg/100 g body weight dose of nicotine injected subcutaneously on a daily basis (Sigma Chemical Company, St. Louis, MO, USA); the Nicotine-Alcohol group received simultaneous alcohol and nicotine treatment. After 90 days of treatment, samples of the ventral lobe of the prostate were collected and processed for immunohistochemistry, light microscopy and the quantification of serum hormonal concentrations. The results showed significantly decreased serum testosterone levels and increased serum oestrogen levels in the animals from the nicotine-alcohol, the alcoholic and the nicotine groups, as well as their hormonal receptor levels. Then, it was concluded that ethanol and nicotine compromised the prostatic hormonal balance, which is a crucial factor to maintain the morphological and physiological features of this organ.

The shortening the time of treatment as well as quick decrease of symptoms, and mainly the pain have large meaning in treatment of this disease. Combined treatment of fenspiride and typical treatment of otitis media permits as our investigations show on quicker and observed at children's larger number decrease of symptoms in children with acute otitis media. The aim of the study was to observe effectiveness of combined treatment with antibiotic and fenspiride in children with acute otitis media. The study comprised 40 children (mean age 8.2 years). The diagnosis of acute otitis media based on medical history data, otolaryngological examination and audiometry (tone and impedance). Children with GERD, hypersensitivity to amoxicillin and fenspiride as well as hypertrophy of adenoid were excluded from the study. Children were divided in two equal groups randomly. All children received amoxicillin in dose 80 mg/kg/day in three partite doses (Amotaks, Polfa Tarchomin Poland) as well as oxymethazolin 0.05% nasal drops 3 x day 1-2 drops (0.05% Nasivin, Merck Germany). In children from second group fenspiride was applied in dose 2 ml/kg/day in three divided doses (Eurespal, Servier Francja) additionally. Treatment was provided by 10 days. During the treatment parents made record of recession in 10 point scale, estimating following parameters: the pain of ear, bother, raised the temperature of body, loss of appetite, vomiting, diarrhea, otorrhea and crying. After end of treatment control otolaryngological and audiological examinations were performed. In studied children symptoms were similar, and the pain of ear was in both groups main suffering. Vomiting and diarrhea the most seldom were observed. In children with acute otitis media treated additionally with fenspiride statistically significant (pfenspiride in comparison to children treated only with antibiotic. Earlier return of hearing and

    The effects of acute treatment with sibutramine on the peripheral sympathetic neurotransmission in vas deferens of young rats were still not evaluated. Therefore, we carried out this study in order to verify the effects of acute sibutramine treatment on the neuronal- and exogenous agonist-induced contractions of the young rat vas deferens. Young 45-day-old male Wistar rats were pretreated with sibutramine 6 mg/kg and after 4h the vas deferens was used for experiment. The acute treatment with sibutramine was able to increase the potency (pD2) of noradrenaline and phenylephrine. Moreover, the efficacy (Emax) of noradrenaline was increased while the efficacy of serotonin and nicotine were decreased. The maximum effect induced by a single concentration of tyramine was diminished in the vas deferens from treated group. Moreover, the leftward shift of the noradrenaline curves promoted by uptake blockers (cocaine and corticosterone) and β-adrenoceptor antagonist (propranolol) was reduced in the vas deferens of treated group. The initial phasic and secondary tonic components of the neuronal-evoked contractions of vas deferens from treated group at the frequencies of 2 Hz were decreased. Moreover, only the initial phasic component at 5 Hz was diminished by the acute treatment with sibutramine. In conclusion, we showed that the acute treatment with sibutramine in young rats was able to affect the peripheral sympathetic nervous system by inhibition of noradrenaline uptake and reduction of the neuronal content of this neurotransmitter, leading to an enhancement of vas deferens sensitivity to noradrenaline.

    Full Text Available Background: Despite undeniable evidence for the efficacy and effectiveness of Cognitive Behaviour Therapy for Insomnia (CBT-I, the potential for its widespread dissemination and implementation has yet to be realised. A suggested reason for this is that traditional CBT-I is considered too burdensome for deployment, in its current form, within the context of where it would be most beneficial—Primary Care. One strategy, aimed to address this, has been to develop briefer versions of CBT-I, whilst another has been to deliver CBT-I in a group format. An alternative has been to attempt to address insomnia during its acute phase with a view to circumventing its progression to chronic insomnia. The aim of the present study was to compare a brief version of CBT-I (one-shot when delivered individually or in groups to those with acute insomnia. Method: Twenty-eight individuals with acute insomnia (i.e., meeting full DSM-5 criteria for insomnia disorder for less than three months self-assigned to either a group or individual treatment arm. Treatment consisted of a single one-hour session accompanied by a self-help pamphlet. Subjects completed measures of insomnia severity, anxiety and depression pre-treatment and at one-month post-treatment. Additionally, daily sleep diaries were compared between pre-treatment and at the one-month follow up. Results: There were no significant between group differences in treatment outcome on any sleep or mood measures although those in the group treatment arm were less adherent than those who received individual treatment. Furthermore, the combined (group and individual treatment arms pre-post test effect size on insomnia symptoms, using the Insomnia Severity Index, was large (d = 2.27. Discussion: It appears that group treatment is as efficacious as individual treatment within the context of a “one shot” intervention for individuals with acute insomnia. The results are discussed with a view to integrating one-shot CBT

    Full Text Available Background. The purpose of the study was to evaluate the effectiveness of traditional and optimized programs for integrated treatment and prevention of clinical and laboratory manifestations of hepatic dysfunction in acute biliary pancreatitis in patients with diabetes mellitus by observing the dynamics of markers of cytopathic hypoxia, erythron system and iron metabolism. Materials and methods. The work is based on the analysis of the results of the comprehensive treatment of 122 patients with acute biliary pancreatitis against the background of diabetes mellitus. Laboratory analysis was performed to monitor markers of cytopathic hypoxia, erythron system and iron metabolism depending on the morphological form of acute pancreatitis and the effectiveness of optimized and traditional treatment. Results. The interstitial form of acute biliary pancreatitis in diabetes mellitus is characterized by significant changes in the dynamics of carbonyl groups, the content of arginine and adenosine deamination on the background of physiological fluctuations of the remaining markers of cytopathic hypoxia, and the signs of a distinct functional iron deficiency state in the form of microcytosis and hypochromia were detected. The emergence of pancreatic parenchyma necrosis of different planes, depending on the morphological form of acute biliary pancreatitis, is accompanied by reliable evidence of an absolute iron deficiency state of varying intensity and negative dynamics of indicators of endothelial dysfunction with a separate form. In patients with widespread necrotizing acute biliary pancreatitis, the pathological changes in the systemic metabolism are associated with the catabolism of purine nucleotides — the growth of xanthine and hypoxanthine levels. The stage of decompensation of systemic disorders of homeostasis is observed in patients with subtotal-total forms, when additional increase in the concentrations of enzymes responsible for utilization of

    Mohammad Sayed and Ahmed Abdel Rady

    Full Text Available This investigation was run in some villages in Assiut governance during summer 2007 to diagnose acute clinical mastitis in different animal species and to apply different lines of treatment for evaluating which treatment line of choice giving cure, aiming to another goal by preventing the conversion of acute mastitis towards the chronic one which is difficult to be treated and the dairy animal will be excluded. Therefore, 2150 animals were clinically examined in 5 villages located north to Assiut city, Egypt, including 400 cows, 950 ewes and 800 she goats, and the incidence of acute clinical mastitis was 22.50%, 2.63% and 4.63%, respectively. Milk samples were collected from all clinically mastitic cows for bacteriological examination to identify the causative agents of the intra-mammary infection (IMI. It was found the major causative agents isolated were Staphylococcus aureus, Streptococcus agalactiae, Escherichia coli and Corynebacterium pyogenes, causing either single or mixed type of infection. When applying different lines of treatment, all diseased animals were classified into 3 groups: 1st group received local treatment by intra-mammary infusion antibiotic. 2nd group received systematic treatment by intra-muscular (I/M injection of both antibiotic and anti-inflammatory drugs. While, 3rd group received combination of both local and systematic treatment lines together. Cure% was achieved as 50% for 1st group, 90% for 2nd group, while 3rd group gave complete cure by 100%. It was noticed that the incidence of acute clinical mastitis among examined cows was worrisome and can be considered as indicator of the epidemiology of the disease. While, spreading of the disease among ewes and she goats was somewhat low in comparison with that of cows. In conclusion, combination of both local and systematic treatment lines together should be advised in treatment of acute clinical mastitis to ensure complete cure. The obtained results highlighted the

    This study assessed long-lasting consequences of repeated ethanol exposure during two different periods of adolescence on 1) baseline levels of social investigation, play fighting, and social preference and 2) sensitivity to the social consequences of acute ethanol challenge. Adult male and female Sprague-Dawley rats were tested 25 days after repeated exposure to ethanol (3.5 g/kg intragastrically [i.g.], every other day for a total of 11 exposures) in a modified social interaction test. Early-mid adolescent intermittent exposure (e-AIE) occurred between postnatal days (P) 25 and 45, whereas late adolescent intermittent exposure (l-AIE) was conducted between P45 and P65. Significant decreases in social investigation and social preference were evident in adult male rats, but not their female counterparts following e-AIE, whereas neither males nor females demonstrated these alterations following l-AIE. In contrast, both e-AIE and l-AIE produced alterations in sensitivity to acute ethanol challenge in males tested 25 days after adolescent exposure. Ethanol-induced facilitation of social investigation and play fighting, reminiscent of that normally seen during adolescence, was evident in adult males after e-AIE, whereas control males showed an age-typical inhibition of social behavior. Males after l-AIE were found to be insensitive to the socially suppressing effects of acute ethanol challenge, suggesting the development of chronic tolerance in these animals. In contrast, females showed little evidence for alterations in sensitivity to acute ethanol challenge following either early or late AIE. The results of the present study demonstrate a particular vulnerability of young adolescent males to long-lasting detrimental effects of repeated ethanol. Retention of adolescent-typical sensitivity to the socially facilitating effects of ethanol could potentially make ethanol especially appealing to these males, therefore promoting relatively high levels of ethanol intake later

    In 64 patients with lung cancer complicated by idiopathic interstitial pneumonia (IIP), we retrospectively studied the outcome of the treatment for lung cancer and clinical features of acute exacerbation of IIP after treatment for lung cancer. The incidence of acute exacerbation of IIP was 8.7% (2 of 23 patients) after anticancer chemotherapy, 14.3% (2 of 14 patients) after operation, and 25% (2 of 8 patients) after radiation therapy. Serum C-reactive protein level was significantly higher in the patients who developed acute exacerbation of IIP than in those who did not (CRP=5.12±2.27, 2.26±2.29, respectively). On the contrary, there were no differences in the levels of serum lactate dehydrogenase, white blood cell count, erythrocyte sedimentation rate, PaO 2 , and %VC between the two groups. Pathologic presentations of surgically resected lungs did not show significant differences in the activity of IIP between the two groups. Five of 6 patients who developed acute exacerbation of IIP died within 3 months after the treatment for lung cancer. We conclude that we should evaluate the activity of IIP more precisely using new markers for activity of IIP and on that basis select patients to be treated for lung cancer. (author)

    To compare the acute toxicities in radical treatment of prostate cancer between conventional schedule (C-ARM) with 78 Gy/39 fractions and hypofractionation conformal treatment (H-ARM) with 69 Gy/23 fractions. This prospective double arm study consisted of 217 patients with prostate cancer, 112 in H-ARM and 105 in C-ARM arm. C-ARM received conventional six- field conformal radiotherapy with 78 Gy in 39 fractions while H-ARM received hypofractionation with 69 Gy in 23 fractions. Weekly assessment of acute reactions was done during treatment and with one, and 3 months using RTOG scale. Univariated analysis was performed to evaluate differences between the incidences of acute reaction in the treatment arms. Variables with p value less than 0.1 were included in the multivariated logistic regression. There was no difference between H-ARM versus C-ARM for severity and incidence in genitourinary (GU) and gastrointestinal (GI) acute toxicity. During the treatment comparing H-ARM with C-ARM no differences was observed for GI toxicity (grade 0–3; H-ARM = 45.5%, 34%, 18.7% and 1.8% versus C-ARM = 47.6%, 35.2%, 17.2% and 0). For acute GU toxicity no difference was detected between H-ARM (grade 0–3; 22.3%, 54.5%, 18.7% and 4.5%) and C-ARM (grade 0–3; 25.8%, 53.3%, 17.1% and 3.8%). At the 3- months follow-up, persistent Grade > =2 acute GU and GI toxicity were 2.5% and 1.8% in H-ARM versus 5.7% and 3% in C-ARM (p > 0.05). In univariated and multivariated analyses, there was not any dosimetric predictor for GI and GU toxicity. Our data demonstrate that hypofractionated radiotherapy achieving high biological effective dose using conformal radiotherapy is feasible for prostate cancer, being well tolerated with minimal severe acute toxicity

    Children with Down syndrome (DS) have an elevated risk of developing acute leukemia, but little is known about treatment-related neuropsychological morbidity because they are systematically excluded from research in this area. The current study investigated neuropsychological outcomes in children with DS treated for acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML) compared to children with DS with no history of cancer. Participants were 4 to 17 years of age at testing and were administered measures of intelligence, academic achievement, language, visual-motor and fine-motor skills, and adaptive function. Patients had been off treatment for at least 2 years. The AML group (N = 12) had significantly lower verbal intelligence and receptive vocabulary compared to controls (N = 21). By contrast, the ALL group (N = 14) performed significantly worse than controls on measures of verbal intelligence, spelling, receptive and expressive vocabulary, visual-motor skills, and adaptive function. Patients with DS treated for AML may have specific post-treatment morbidity in verbal function, whereas those treated for ALL have broader morbidity affecting multiple neuropsychological domains and overall adaptive function. We hypothesize that the broader impairment profile of ALL survivors may be related to a combination of the longer duration of central nervous system-directed treatment for ALL compared to AML and the concomitant limited access to intervention opportunities during active treatment. © 2014 Wiley Periodicals, Inc.

    There have been major advances in our understanding of the multiple interactions between malignant cells and the innate and adaptive immune system. While the attention of immunologists has hitherto focused on solid tumors, the specific immunobiology of acute leukemias is now becoming defined. These discoveries have pointed the way to immune interventions building on the established graft-versus-leukemia (GVL) effect from hematopoietic stem-cell transplant (HSCT) and extending immunotherapy beyond HSCT to individuals with acute leukemia with a diversity of immune manipulations early in the course of the leukemia. At present, clinical results are in their infancy. In the coming years larger studies will better define the place of immunotherapy in the management of acute leukemias and lead to treatment approaches that combine conventional chemotherapy, immunotherapy and HSCT to achieve durable cures.

    Non-traumatic convexal subarachnoid hemorrhage (CSAH) is a comparatively infrequent with various vascular and nonvascular causes, it rarely occurs concomitant to acute ischemic stroke. We report a case of a 59-year-old woman, visited emergency room with right side subjective weakness spontaneously. Magnetic resonance diffusion-weighted images revealed an acute infarction of anterior cerebral arterial territory. Computed tomographic angiography showed a left frontal CSAH without any vascular lesions. And other laboratory studies were non-specific. We treated with dual antiplatelet drugs (cilostazole [Otsuka Pharmaceutical Co., Ltd. tokyo, Japan] and Aspirin [Bayer Pharma AG., Leverkusen, Germany]). She has done well for a follow-up period. (5 months) This case demonstrates the CSAH with acute infarction is rare but need to work up to identify the etiology and antiplatelet dugs are taken into account for treatments.

    We studied the effect of early antihypertensive treatment on death, major disability, and vascular events among patients with acute ischemic stroke according to their baseline SBP. We randomly assigned 4071 acute ischemic stroke patients with SBP between 140 and less than 220 mmHg to receive antihypertensive treatment or to discontinue all antihypertensive medications during hospitalization. A composite primary outcome of death and major disability and secondary outcomes were compared between treatment and control stratified by baseline SBP levels of less than 160, 160-179, and at least 180 mmHg. At 24 h after randomization, differences in SBP reductions were 8.8, 8.6 and 7.8 mmHg between the antihypertensive treatment and control groups among patients with baseline SBP less than 160, 160-179, and at least 180 mmHg, respectively (P baseline SBP subgroups on death (P = 0.02): odds ratio (95% CI) of 2.42 (0.74-7.89) in patients with baseline SBP less than 60 mmHg and 0.34 (0.11-1.09) in those with baseline SBP at least 180 mmHg. At the 3-month follow-up, the primary and secondary clinical outcomes were not significantly different between the treatment and control groups by baseline SBP levels. Early antihypertensive treatment had a neutral effect on clinical outcomes among acute ischemic stroke patients with various baseline SBP levels. Future clinical trials are warranted to test BP-lowering effects in acute ischemic stroke patients by baseline SBP levels. ClinicalTrials.gov Identifier: NCT01840072.

    Hepatic protein synthetic activity in vivo was measured by the incorporation of [ 3 H]puromycin into elongating nascent polypeptides of rat liver to form peptidyl-[ 3 H]puromycin. Our initial experiments showed that saturating doses of [ 3 H]puromycin were achieved at 3-6 mumol/100 g body weight, and that maximum labeling of nascent polypeptides was obtained 30 min after injection of the labeled precursor. Labeled puromycin was found to be suitable for measuring changes in the status of protein synthesis, since the formation of the peptidyl-[ 3 H]puromycin was decreased in fasted animals and was increased in rats pretreated with L-tryptophan. [ 3 H]Puromycin incorporation into polypeptides was then measured after acute ethanol administration as well as after prolonged consumption of ethanol which was administered as part of a liquid diet for 31 days. Acute alcohol treatment caused no significant change in [ 3 H]puromycin incorporation into liver polypeptides. In rats exposed to chronic ethanol feeding, peptidyl-[3H]puromycin formation, when expressed per mg of protein, was slightly lower compared to pair-fed controls, but was unchanged compared to chow-fed animals. When the data were expressed per mg of DNA or per 100 g body wt, no differences in protein synthetic activity were observed among the three groups. These findings indicate that neither acute nor chronic alcohol administration significantly affects protein synthetic activity in rat liver. They further suggest that accumulation of protein in the liver, usually seen after prolonged ethanol consumption, is apparently not reflected by an alteration of hepatic protein synthesis

    Objective: To investigate the clinical effect of compound monoammonium glycyrrhizinate combined with dandelion in the treatment of acute paraquat poisoning. Methods: A total of 80 patients with acute paraquat poisoning who were admitted to our hospital were enrolled as study subjects and randomly divided into routine treatment group (38 patients) and traditional Chinese medicine (TCM) group (42 patients) . The patients in the TCM group were given compound monoammonium glycyrrhizinate and dandelion in addition to the treatment in the control group. Serum alanine aminotransferase (ALT) , total bilirubin (TBil) , blood urea nitrogen (BUN) , creatinine (Cr) , and arterial blood lactate (Lac) and partial pressure of oxygen (PaO 2 ) during different time periods on day 3, 7, and 9 of treatment were observed in both groups, and ulceration of oral mucosa, pulmonary fibrosis, multiple organ dysfunction syndrome (MODS) , and mortality were compared between the two groups. Results: On days 3, 7, and 9 of treatment, the routine treatment group had significantly higher serum ALT, TBil, BUN, Cr, and arterial blood Lac than the TCM group. The routine treatment group had significantly lower arterial blood PaO 2 than the TCM group, while the TCM group had significantly lower incidence rates of ulceration of oral mucosa, pulmonary fibrosis, and MODS and a significantly lower mortality rate than the routine treatment group ( P treatment of patients with acute paraquat poisoning, compound monoammonium glycyrrhizinate combined with dandelion can effectively improve organ function, reduce the incidence of pulmonary fibrosis and MODS, improve the healing rate of oral ulcer, improve prognosis, and reduce mortality rate.

    Full Text Available Organ failure is an important factor causing death in patients with severe acute pancreatitis (SAP. In recent years, thanks to the further study of pathophysiology of SAP and the continuous accumulation of experience and technology, substantial progress has been made in the diagnosis and treatment of SAP complicated by organ failure. The clinical features of SAP complicated by organ failure and the measures to be strengthened in the treatment of SAP are summarized. Currently, it is thought that organ failure tends to appear once SAP occurs, so timely, standardized treatment can shorten the course of disease and significantly reduce mortality.

    Full text: Background and Objectives: After an assessment of peanut-based RUTF in Cambodia found low acceptability rates, the National Institute of Nutrition Vietnam, UNICEF and the Institut de Recherche pour le Développement started in 2009 to work on a locally produced RUTF, adapted to local taste and preference for the treatment of severe acute malnutrition (SAM). In 2010, the newly developed product was found to be highly acceptable, but impact on weight gain needed to be proven. Therefore, this study was conducted to assess the effectiveness of the local RUTF on weight gain and recovery rate using the RUTF in a home based treatment of acute malnutrition. Methods and Design: The study was a randomized intervention trial in 150 children, aged 6-59 months, with SAM or moderate acute malnutrition (MAM) to test the effectiveness of the local RUTF (bar) against a standard RUTF (peanut-based paste). The study was done as a community-based intervention trial in Kon Tum province (Central Highlands region), Vietnam, where an Integrated Management of Acute Malnutrition programs (IMAM) program was just being introduced. Results: Children consumed 92% and 70% of the offered local RUTF and standard RUTF respectively, underlining the problems with a peanut-based RUTF in SE Asia. Nutritional status of the children was significantly improved after the 8 weeks intervention. Mean weight gain with the standard RUTF and the local RUTF was 2.97 (± 1.57) g/kg/d and 2.52 (± 1.23) g/kg/d respectively. Also, both RUTFs improved significantly height and HAZ-scores, with a mean height gain of 22.4 (±18.7) mm and 32.3 (±36.3) mm for respectively standard and local RUTF. The recovery rate from acute malnutrition with RUTFs as home treatment was 70.8%, and not different between the 2 interventions. Conclusions: The local RUTF was as effective as the standard RUTF on the treatment of acute malnutrition, whereas acceptability was higher. The local RUTF can be successfully used in the

  12. Temporal Profiles Dissociate Regional Extracellular Ethanol versus Dopamine Concentrations

    Science.gov (United States)

    2015-01-01

    In vivo monitoring of dopamine via microdialysis has demonstrated that acute, systemic ethanol increases extracellular dopamine in regions innervated by dopaminergic neurons originating in the ventral tegmental area and substantia nigra. Simultaneous measurement of dialysate dopamine and ethanol allows comparison of the time courses of their extracellular concentrations. Early studies demonstrated dissociations between the time courses of brain ethanol concentrations and dopaminergic responses in the nucleus accumbens (NAc) elicited by acute ethanol administration. Both brain ethanol and extracellular dopamine levels peak during the first 5 min following systemic ethanol administration, but the dopamine response returns to baseline while brain ethanol concentrations remain elevated. Post hoc analyses examined ratios of the dopamine response (represented as a percent above baseline) to tissue concentrations of ethanol at different time points within the first 25–30 min in the prefrontal cortex, NAc core and shell, and dorsomedial striatum following a single intravenous infusion of ethanol (1 g/kg). The temporal patterns of these “response ratios” differed across brain regions, possibly due to regional differences in the mechanisms underlying the decline of the dopamine signal associated with acute intravenous ethanol administration and/or to the differential effects of acute ethanol on the properties of subpopulations of midbrain dopamine neurons. This Review draws on neurochemical, physiological, and molecular studies to summarize the effects of acute ethanol administration on dopamine activity in the prefrontal cortex and striatal regions, to explore the potential reasons for the regional differences observed in the decline of ethanol-induced dopamine signals, and to suggest directions for future research.

    Purpose: To assess the frequency, mode of presentation, treatment, and outcome of acute complications in patients with craniopharyngioma around the time of radiotherapy. Methods and Materials: A review was made of 188 patients with craniopharyngioma treated with conservative surgery and external beam radiotherapy at the Royal Marsden Hospital between 1950 and 1992. Results: Twenty six (14%) (95% confidence interval: 9-19%) patients with craniopharyngioma developed acute deterioration immediately before, during and 2 months after radiotherapy with visual deterioration (19 patients), hydrocephalus (7 patients), and global deficit (7 patients). Cystic enlargement with or without hydrocephalus was the most common cause of deterioration. No patient or disease characteristics were predictive of deterioration on univariate or multivariate analysis. Eighteen patients had surgical intervention at the time of deterioration and survived the immediate period. Six of seven patients who did not have surgical intervention died. All patients who survived the postcomplication period completed the full course of external beam radiotherapy. The 10-year progression-free survival of 162 patients without deterioration was 86%, and of 18 patients with acute deterioration who recovered after surgery, 77%. Conclusion: Patients with craniopharyngioma develop acute deterioration around the time of radiotherapy owing to cystic enlargement and/or hydrocephalus which does not represent tumor progression. Early recognition and appropriate surgical treatment followed by conventional full-dose radiotherapy are associated with good long-term outcome

    To investigate changes in bacterial counts in subgingival plaque from patients with acute periodontal abscess by IAI-PadoTest. Ninety-one patients were randomly allocated to either test or control groups. In all the patients, pockets with acute periodontal abscess were irrigated with sterilized physiological saline, and in the test group, 2% minocycline hydrochloride ointment was applied once into the pocket in addition. Subgingival plaque samples were collected by paper point before treatment and 7 days after treatment. The total bacterial count was determined and Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, were detected using IAI-PadoTest, a DNA/RNA probe method. The total bacterial count decreased in both groups, with a significant decrease in the test group. The counts and number of sites positive for P. gingivalis, T. forsythia and T. denticola significantly decreased in the test group after treatment, compared with those in the control group. Pocket depth decreased in the both groups, with a statistically significant decrease in the test group. Topical treatment with minocycline in pockets with acute periodontal abscess was effective in reducing the bacterial counts as shown by the microbiological investigation using PadoTest 4.5.

    Ischemic animal model studies have shown a neuroprotective effect of minocycline. To analyze the effect of minocycline treatment in human acute ischemic stroke. We performed an open-label, evaluator-blinded study. Minocycline at a dosage of 200 mg was administered orally for 5 days. The therapeutic window of time was 6 to 24 hours after onset of stroke. Data from NIH Stroke Scale (NIHSS), modified Rankin Scale (mRS), and Barthel Index (BI) were evaluated. The primary objective was to compare changes from baseline to day 90 in NIHSS in the minocycline group vs placebo. One hundred fifty-two patients were included in the study. Seventy-four patients received minocycline treatment, and 77 received placebo. NIHSS and mRS were significantly lower and BI scores were significantly higher in minocycline-treated patients. This pattern was already apparent on day 7 and day 30 of follow-up. Deaths, myocardial infarctions, recurrent strokes, and hemorrhagic transformations during follow-up did not differ by treatment group. Patients with acute stroke had significantly better outcome with minocycline treatment compared with placebo. The findings suggest a potential benefit of minocycline in acute ischemic stroke.

    This study investigated the production of ethanol from unutilized branches pruned from pear trees by steam explosion pretreatment. Steam pressures of 25, 35, and 45 atm were applied for 5 min, followed by enzymatic saccharification of the extracted residues with cellulase (Cellic CTec2). High glucose recoveries, of 93.3, 99.7, and 87.1%, of the total sugar derived from the cellulose were obtained from water- and methanol-extracted residues after steam explosion at 25, 35, and 45 tm, respectively. These values corresponded to 34.9, 34.3, and 27.1 g of glucose per 100 g of dry steam-exploded branches. Simultaneous saccharification and fermentation experiments were done on water-extracted residues and water- and methanol-extracted residues by Kluyveromyces marxianus NBRC 1777. An overall highest theoretical ethanol yield of 76% of the total sugar derived from cellulose was achieved when 100 g/L of water- and methanol-washed residues from 35 atm-exploded pear branches was used as substrate.

    To evaluate the organelle-based changes in acinar cells in experimental acute necrotizing pancreatitis (ANP) after taurine treatment and the association of electron microscopic findings with histopathalogical changes and oxidative stress markers. The study was performed in February 2005at Gulhane School of Medicine and Hacettepe University, Turkey. Forty-five rats were divided into 3 groups. Acute necrotizing pancreatitis was induced in groups II and III. Groups I and II were treated with saline and Group III with taurine 1000mg/kg/day, i.p, for 48 hours. Histopathological and ultrastructural examinations were determined using one-way analysis of variance and Kruskal-Wallis tests. Histopathologic findings improved significantly after taurine treatment. Degree of injury in rough and smooth endoplasmic reticulums, Golgi apparatus, mitochondria and nucleus of acinar cells also decreased with taurine in correlation with biochemical and histological results. Taurine improves acinar cell organelle structure, and ultrastructural recovery in ANP reflects histological improvement. (author)

    Acute exacerbations in patients with chronic bronchitis are a leading cause of hospitalizations and death. Bacteria contribute significantly to such exacerbations. The aim of this review was to explore the potential role of investigational antibiotics in the treatment of these episodes. Areas covered: The available literature in PubMed database, in websites related to investigational drugs and in websites of the producing companies has been searched. The in vitro activity against pathogens involved in acute exacerbations of chronic bronchitis and the pharmacokinetic profile of antibiotics currently under development were taken into consideration for inclusion in the review. Expert opinion: Several novel antimicrobial agents have completed preclinical and Phase I studies and were well-tolerated. Further investigation is mandatory in order to evaluate their future in treatment of chronic bronchitis exacerbations and discover potential advantages compared to already approved antimicrobials.

    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.

    Full Text Available Anticoagulant-related nephropathy (ARN was initially described in patients on warfarin (as warfarin-related nephropathy and recently in those using dabigatran. Herein, we report clinical history and kidney biopsy findings in a patient on apixaban (Eliquis. Initiation of treatment with apixaban resulted in aggravation of preexisting mild acute kidney injury (AKI. A few days after apixaban therapy, the patient became oligoanuric, and kidney biopsy showed severe acute tubular necrosis with numerous occlusive red blood cell casts. Only one out of 68 glomeruli with open capillary loops had small segmental cellular crescent. Therefore, there was major discrepancy between the degree of glomerular injury and the glomerular hematuria. Considering that the onset of this AKI was associated with apixaban treatment initiation, we propose that this patient had ARN associated with factor Xa inhibitor (apixaban, which has not previously been described. Monitoring of kidney function is recommended after initiation of anticoagulant therapy.

    To explore the clinical efficacy of early application of sequential gastrointestinal lavage in patients with acute paraquat poisoning by analyzing the clinical data of 97 patients. A total of 97 eligible patients with acute paraquat poisoning were divided into conventional treatment group (n = 48) and sequential treatment group (n = 49). The conventional treatment group received routine gastric lavage with water. Then 30 g of montmorillonite powder, 30 g of activated charcoal, and mannitol were given to remove intestinal toxins once a day for five days. The sequential treatment group received 60 g of montmorillonite powder for oral administration, followed by small-volume low-pressure manual gastric lavage with 2.5%bicarbonate liquid. Then 30 g of activated charcoal, 30 g of montmorillonite powder, and polyethylene glycol electrolyte lavage solution were given one after another for gastrointestinal lavage once a day for five days. Both groups received large doses of corticosteroids, blood perfusion, and anti-oxidation treatment. The levels of serum potassium, serum amylase (AMY) alanine aminotransferase (ALT), total bilirubin (TBIL), blood urea nitrogen (BUN), creatinine (Cr), lactate (Lac), and PaO₂of patients were determined at 1, 3, 5, 7, and 10 days. Laxative time, mortality, and survival time of dead cases were evaluated in the two groups. The incidence rates of hypokalemia (110 U/L) were significantly lower in the sequential treatment group than in the conventional treatment group (P 80 U/L), TBIL (>34.2 µmol/L), BUN (>7.2 mmol/L), and Cr (>177 µmol/L) between the two groups (P>0.05). However, the highest levels of ALT, TBIL, BUN, Cr, and Lac were significantly lower in the sequential treatment group than in the conventional treatment group (P treatment group had significantly lower incidence of PaO₂(treatment group (P poisoning.

    Stress alters physiology and behavior across species. Most research on the effects of stress on behavior uses chronic stressors, and most are correlational. The effects of acute stressors on physiology and behavior have been mixed. Here, we use zebra finches, a highly gregarious species that forms long-term pair bonds, to test the effects of an acute corticosterone (CORT) on opposite-sex partner preferences over a same-sex individual or a group (the latter is a highly appealing option). We had two competing hypotheses. First, we predicted that acute CORT would alter preferences for the opposite sex bird in both conditions in both sexes. However, since there is a sex difference in the effects of CORT on partner preferences in voles, these effects may be more pronounced in males than in females. To test our hypotheses, we administered 2 doses of CORT (10μg and 20μg) or vehicle (control) using a repeated measures design. In the male vs. female test, there was a significant Sex by Treatment interaction, such that in males, 10μg CORT increased preferences for a female over the male compared to when these same males were treated with saline at baseline. There were no effects of treatment in females. In the opposite-sex vs. group condition, there was an overall effect of Treatment, such that the 10μg dose increased preference for the opposite-sex individual over both saline treatments, regardless of sex. These findings further our understanding of the effects of an acute stressor on sexual partner preferences. Copyright © 2014 Elsevier Inc. All rights reserved.

    Aim: The aim of this study was to evaluate the efficacy of endovascular treatment for acute arterial complications following living-donor liver transplantation (LDLT). Materials and methods: Of 79 LDLT patients, 17 (mean age 48 {+-} 8 years, range 33-66 years) who had acute arterial complications and underwent endovascular treatment were evaluated. Transcatheter arterial embolization was performed to control peritoneal bleeding. Catheter-directed thrombolysis using urokinase was performed in hepatic artery thromboses. The locations of complications and materials used were evaluated. The technical and clinical success rates were calculated. Results: Twenty-three acute arterial complications, including four hepatic artery thromboses and 19 cases of peritoneal haemorrhages were identified in 22 angiographic sessions in 17 patients. The mean duration between LDLT and first angiography was 3.2 {+-} 3.5 days (range 1-13 days). Hepatic artery recanalization with catheter-directed thrombolysis using urokinase was achieved in two patients. Transcatheter arterial embolization for peritoneal bleeding was successfully performed in 16 cases. The most common bleeding focus was the right inferior phrenic artery. Additional surgical management was needed in five patients to control bleeding or hepatic artery recanalization. Technical and clinical success rates of transcatheter arterial embolization were 84.2 and 63.1%, respectively. Overall technical success was achieved in 18 of 23 arterial complications (78.2%), and clinical success was achieved in 14 of 23 arterial complications (60.8%). Conclusion: Endovascular treatment for the acute arterial complications of haemorrhage or thrombosis in LDLT patients is safe and effective. Therefore, it should be considered as the first line of treatment in selective cases.

    A natural source of medicine, Enicosanthellum pulchrum is a tropical plant which belongs to the family Annonaceae. In this study, methanol extract from the leaves and stems of this species was evaluated for its gastroprotective potential against mucosal lesions induced by ethanol in rats. Seven groups of rats were assigned, groups 1 and 2 were given Tween 20 (10% v/v) orally. Group 3 was administered omeprazole 20 mg/kg (10% Tween 20) whilst the remaining groups received the leaf and stem extracts at doses of 150 and 300 mg/kg, respectively. After an additional hour, the rats in groups 2-7 received ethanol (95% v/v; 8 mL/kg) orally while group 1 received Tween 20 (10% v/v) instead. Rats were sacrificed after 1 h and their stomachs subjected to further studies. Macroscopically and histologically, group 2 rats showed extremely severe disruption of the gastric mucosa compared to rats pre-treated with the E. pulchrum extracts based on the ulcer index, where remarkable protection was noticed. Meanwhile, a significant percentage of inhibition was shown with the stem extract at 62% (150 mg/kg) and 65% (300 mg/kg), whilst the percentage with the leaf extract at doses of 150 and 300 mg/kg was 63% and 75%, respectively. An increase in mucus content, nitric oxide, glutathione, prostaglandin E2, superoxide dismutase, protein and catalase, and a decrease in malondialdehyde level compared to group 2 were also obtained. Furthermore, immunohistochemical staining of groups 4-7 exhibited down-regulation of Bax and up-regulation of Hsp70 proteins. The methanol extract from the leaves and the stems showed notable gastroprotective potential against ethanol.

  13. Functional interaction and cross-tolerance between ethanol and Δ9-THC: possible modulation by mouse cerebellar adenosinergic A1/GABAergic-A receptors.

    We have previously shown a functional motor interaction between ethanol and Δ(9)-tetrahydrocannabinol (Δ(9)-THC) that involved cerebellar adenosinergic A1 and GABAergic A receptor modulation. We now report the development of cross-tolerance between intracerebellar Δ(9)-THC and intraperitoneal ethanol using ataxia as the test response in male CD-1 mice. The drugs [Δ(9)-THC (20 μg), N(6)-cyclohexyladenosine, CHA (12 ng), muscimol (20 ng)] used in the study were directly microinfused stereotaxically via guide cannulas into the cerebellum except ethanol. Δ(9)-THC, infused once daily for 5 days followed 16 h after the last infusion by acute ethanol (2g/kg) and Rotorod evaluation, virtually abolished ethanol ataxia indicating development of cross-tolerance. The cross-tolerance was also observed when the order of ethanol and Δ(9)-THC treatment was reversed, i.e., ethanol injected once daily for 5 days followed 16 h after the last ethanol injection by Δ(9)-THC infusion. The cross-tolerance appeared within 24-48 h, lasted over 72 h and was maximal in 5-day ethanol/Δ(9)-THC-treated animals. Finally, tolerance in chronic ethanol/Δ(9)-THC/-treated animals developed not only to ethanol/Δ(9)-THC-induced ataxia, respectively, but also to the ataxia potentiating effect of CHA and muscimol, indicating modulation by cerebellar adenosinergic A1 and GABAA receptors. A practical implication of these results could be that marijuana smokers may experience little or no negative effects such as ataxia following alcohol consumption. Clinically, such antagonism of ethanol-induced ataxia can be observed in marijuana users thereby encouraging more alcohol consumption and thus may represent a risk factor for the development of alcoholism in this segment of population.

    OBJECTIVES: The objective was to explore whether prescribing variation is associated with duration of antidepressant use during the acute phase of treatment. Improving quality of care and increasing the extent to which treatment is patient-centered and customized are interrelated goals. Prescribing variation may be considered a marker of customization, and could be associated with better antidepressant treatment adherence. METHODS: A cross-sectional secondary data analysis examining the association between providers' antidepressant prescribing variation and patient continuity of antidepressant treatment. The data source was two states' Medicaid claims for dual-eligible Medicaid/Medicare patients. The sample included 383 patients with new episodes of antidepressant treatment, representing 70 providers with at least four patients in the sample. We tested two alternate measures of prescribing concentration: 1) share of prescriber's initial antidepressant prescribing accounted for by the two most common regimens, and 2) Herfindahl index. The HEDIS performance measure of effective acute-phase treatment (at least 84 out of 114 days with antidepressant) was the dependent variable. KEY FINDINGS: In multivariate analyses, the concentration measure based on the top two regimens was significant and inversely related to duration adequacy (p customized care.

    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
