    This study performed an acute oral toxicity test of 59 compounds in silkworms. These compounds are listed in OECD guidelines as standard substances for a cytotoxicity test, and median lethal dose (LD(50)) werecalculated for each compound. Acute oral LD(50) values in mammals are listed in OECD guidelines and acute oral LD(50) values in silkworms were determined in this study. R(2) for the correlation between LD(50) values in mammals and LD(50) values in silkworms was 0.66. In addition, the acute oral toxicity test in silkworms was performed by two different facilities, and test results from the facilities were highly reproducible. These findings suggest that an acute oral toxicity test in silkworms is a useful way to evaluate the toxicity of compounds in mammals.

    Haloperidol decanoate is a typical antipsychotic drug used as maintenance therapy for schizophrenia and mood disorders formulated as an ester for intramuscular injection. Cases of oral haloperidol decanoate intoxications have not been described in literature. In this report, we present for the first time a case of an oral ingestion of haloperidol decanoate of a young woman who presented to the emergency department following an intentional oral ingestion of 1 ampoule of haloperidol decanoate 100mg. At presentation, she had a bilateral rest tremor of both hands and mild hypothermia. No other obvious signs of an intoxication were observed. She was treated with a single dose of activated charcoal and laxative and was admitted to the intensive care for rhythm monitoring and observation. During the night the QTc interval increased to 453ms, but stayed within the normal range. Haloperidol plasma levels increased as well, but also stayed within therapeutic ranges. These findings indicate that treatment with oral activated charcoal was sufficient to prevent any serious events. Copyright © 2017 Elsevier Inc. All rights reserved.

    Eighty patients with carcinoma in the middle third of oesophagus and with acute radiation oesophagitis following external beam and intracavitary radiotherapy were managed by two different schedules. Group 1 (n = 40) received an antacid containing sodium alginate whereas Group 2 (n = 40) were given a 10% sucralfate suspension during 4 weeks. In Group 2, 32 patients had significant relief of symptoms within 7 days of treatment and most ulcers had healed by 12 days of treatment as seen on endoscopy. Patients in Group 1, on the other hand, showed little improvement of symptoms and had persistent ulcers even after 4 weeks of therapy. We conclude that sucralfate is useful in the management of acute radiation oesophagitis. (orig.).

Of all late complications of treatment, second malignancies are generally considered to be the most serious. We report on a 20-year-old man with an oral squamous cell carcinoma 17 years after initial chemotherapy and irradiation for acute lymphoblastic leukaemia. Although occurrence of the oral malignancy in this patient could have been treatment-related, one should keep in mind that the occurrence of second tumours may also be based on a shared genetic aetiology.

    Full Text Available Gynura bicolor (Compositae which is widely used by the locals as natural remedies in folk medicine has limited scientific studies to ensure its efficacy and nontoxicity. The current study reports the total phenolic content, antioxidant capacity, cytotoxicity, and acute oral toxicity of crude methanol and its fractionated extracts (hexane, ethyl acetate, and water of G. bicolor leaves. Five human colon cancer cell lines (HT-29, HCT-15, SW480, Caco-2, and HCT 116, one human breast adenocarcinoma cell line (MCF7, and one human normal colon cell line (CCD-18Co were used to evaluate the cytotoxicity of G. bicolor. The present findings had clearly demonstrated that ethyl acetate extract of G. bicolor with the highest total phenolic content among the extracts showed the strongest antioxidant activity (DPPH radical scavenging assay and metal chelating assay, possessed cytotoxicity, and induced apoptotic and necrotic cell death, especially towards the HCT 116 and HCT-15 colon cancer cells. The acute oral toxicity study indicated that methanol extract of G. bicolor has negligible level of toxicity when administered orally and has been regarded as safe in experimental rats. The findings of the current study clearly established the chemoprevention potential of G. bicolor and thus provide scientific validation on the therapeutic claims of G. bicolor.

    Dracaena cinnabari (DC) is a perennial tree that located on the Southern coast of Yemen native to the Socotra Island. This tree produces a deep red resin known as the Dragon's blood, the Twobrother's Blood or Damm Alakhwain. The current study performed to evaluate the safety of the DC resin methanol extract after a single or 28 consecutive daily oral administrations. In assessing the safety of DC resin methanol extract, acute and sub-acute oral toxicity tests performed following OECD guidelines 423 and 407, respectively, with slight modifications. In acute oral toxicity test, DC resin methanol extract administered to female Sprague Dawley rats by oral gavage at a single dose of 300 and 2000 mg/kg body weight. Rats observed for toxic signs for 14 days. In sub-acute oral toxicity test, DC resin methanol extract administered to the rats by oral gavage at 500, 1000, and 1500 mg/kg body weight daily up to 28 days to male and female Spradgue Dawley rats. The control and high dose in satellite groups were also maintained and handled as the previous groups to determine the late onset toxicity of DC resin methanol extract. At the end of each test, hematological and biochemical analysis of the collected blood were performed as well as gross and microscopic pathology. In acute oral toxicity, no treatment-related death or toxic signs were observed. It revealed that the DC resin methanol extract could be well tolerated up to the dose 2000 mg/kg body weight and could be classified as Category 5. The sub-acute test observations indicated that there are no treatment-related changes up to the high dose level compared to the control. Food consumption, body weight, organ weight, hematological parameters, biochemical parameters and histopathological examination (liver, kidney, heart, spleen and lung) revealed no abnormalities. Water intake was significantly higher in the DC resin methanol extract treated groups compared to the control. This study demonstrates tolerability of DC

    Full Text Available Abstract Background Endodontic infections are a leading cause of oro-facial pain and tooth loss in western countries, and may lead to severe life-threatening infections. These infections are polymicrobial with high bacterial diversity. Understanding the spatial transition of microbiota from normal oral cavities through the infected root canal to the acute periapical abscess can improve our knowledge of the pathogenesis of endodontic infections and lead to more effective treatment. We obtained samples from the oral cavity, infected root canal and periapical abscess of 8 patients (5 with localized and 3 with systemic infections. Microbial populations in these samples were analyzed using next-generation sequencing of 16S rRNA amplicons. Bioinformatics tools and statistical tests with rigorous criteria were used to elucidate the spatial transition of the microbiota from normal to diseased sites. Results On average, 10,000 partial 16S rRNA gene sequences were obtained from each sample. All sequences fell into 11 different bacterial phyla. The microbial diversity in root canal and abscess samples was significantly lower than in the oral samples. Streptococcus was the most abundant genus in oral cavities while Prevotella and Fusobacterium were most abundant in diseased samples. The microbiota community structures of root canal and abscess samples were, however, more similar to each other than to the oral cavity microbiota. Using rigorous criteria and novel bioinformatics tools, we found that Granulicatella adiacens, Eubacterium yurii, Prevotella melaninogenica, Prevotella salivae, Streptococcus mitis, and Atopobium rimae were over-represented in diseased samples. Conclusions We used a novel approach and high-throughput methodologies to characterize the microbiota associated normal and diseased oral sites in the same individuals.

    Full Text Available Background and objectives: Acute apical abscesses are serious endodontic diseases resulting from pulpal infection with opportunistic oral microorganisms. The objective of this study was to identify and compare the oral microbiota in patients (N=18 exhibiting acute apical abscesses, originating from the demographic region in Portland, Oregon. The study hypothesis is that abscesses obtained from this demographic region may contain unique microorganisms not identified in specimens from other regions. Design: Endodontic abscesses were sampled from patients at the Oregon Health & Science University (OHSU School of Dentistry. DNA from abscess specimens was subjected to polymerase chain reaction amplification using 16S rRNA gene-specific primers and Cy3-dCTP labeling. Labeled DNA was then applied to microbial microarrays (280 species generated by the Human Oral Microbial Identification Microarray Laboratory (Forsyth Institute, Cambridge, MA. Results: The most prevalent microorganisms, found across multiple abscess specimens, include Fusobacterium nucleatum, Parvimonas micra, Megasphaera species clone CS025, Prevotella multisaccharivorax, Atopobium rimae, and Porphyromonas endodontalis. The most abundant microorganisms, found in highest numbers within individual abscesses, include F. nucleatum, P. micra, Streptococcus Cluster III, Solobacterium moorei, Streptococcus constellatus, and Porphyromonas endodontalis. Strong bacterial associations were identified between Prevotella multisaccharivorax, Acidaminococcaceae species clone DM071, Megasphaera species clone CS025, Actinomyces species clone EP053, and Streptococcus cristatus (all with Spearman coefficients >0.9. Conclusions: Cultivable and uncultivable bacterial species have been identified in endodontic abscesses obtained from the Portland, Oregon demographic region, and taxa identifications correlated well with other published studies, with the exception of Treponema and Streptococcus cristae, which

    Background Flurbiprofen is a non-selective non-steroidal anti-inflammatory drug (NSAID), related to ibuprofen and naproxen, used to treat acute and chronic painful conditions. There is no systematic review of its use in acute postoperative pain. Objectives To assess efficacy, duration of action, and associated adverse events of single dose oral flurbiprofen in acute postoperative pain in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to January 2009. Selection criteria Randomised, double blind, placebo-controlled trials of single dose orally administered flurbiprofen in adults with moderate to severe acute postoperative pain. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk (RR) and number needed to treat to benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. Main results Eleven studies compared flurbiprofen (699 participants) with placebo (362 participants) in studies lasting 6 to 12 hours. Studies were of adequate reporting quality, and most participants had pain following dental extractions. The dose of flurbiprofen used was 25 mg to 100 mg, with most information for 50 mg and 100 mg. The NNT for at least 50% pain relief over 4 to 6 hours for flurbiprofen 50 mg compared with placebo (692 participants) was 2.7 (2.3 to 3.3) and for 100 mg (416 participants) it was 2.5 (2.0 to 3.1). With flurbiprofen 50 mg and 100 mg 65% to 70% of participants experienced at least 50% pain relief, compared with 25% to 30% with placebo. Rescue medication was used by 25

    To evaluate the effect of oral hygiene care of patients with oral cancer on alleviating acute radiation mucositis. Eighteen patients receiving postoperative radiotherapy for tongue and oral floor cancer were evaluated. Radiotherapy was given in 2 Gy per fraction, 5 times a week for a total dose of 50 Gy in most patients. Radiation field included the tongue and oral floor. During radiotherapy, 8 patients were treated by dento-maxillofacial radiologists with special concern on oral hygiene (oral hygiene group) and the remaining 10 patients were treated with routine dental care (standard medication group). Mucositis were evaluated using JCOG grade and EORTC/RTOG score by radiotherapists or dento-maxillofacial radiologists at 10 Gy intervals. Oral hygiene plans comprised motivation to maintain oral hygiene and establishing the habits of oral self care 4 times per day. Once a week, oral hygiene and oral cleaning of patients were checked by dento-maxillofacial radiologists. Oral self care included mechanical tooth brushing and a chemical mouthwash. No patients with grade 3 and score 4 mucositis were noted in the oral hygiene group. Severe mucositis occurred less frequently in the oral hygiene group than in the standard medication group. Interruption of radiotherapy due to severe mucositis did not occur in the oral hygiene group. On the other hand, interruption of radiotherapy occurred in four patients in the standard medication group, and in three it was due to severe oral pain. Our results suggested that our method of oral hygiene was more effective for alleviating acute radiation mucositis than other methods so far reported. In addition, our method is considered to be useful in preventing rampant dental caries and severe periodontitis due to the xerostomia induced by radiotherapy. (author)

    Elevated serum phosphate is consistently linked with cardiovascular disease (CVD) events and mortality in the setting of normal and impaired kidney function. However, serum phosphate does not often exceed the upper limit of normal until glomerular filtration rate (GFR) falls below 30 mL/min/m 2 . It was hypothesized that the response to an oral, bioavailable phosphate load will unmask impaired phosphate tolerance, a maladaptation not revealed by baseline serum phosphate concentrations. In this study, rats with varying kidney function as well as normo-phosphatemic human subjects, with inulin-measured GFR (13.2 to 128.3mL/min), received an oral phosphate load. Hormonal and urinary responses were evaluated over 2 hours. Results revealed that the more rapid elevation of serum phosphate was associated with subjects and rats with higher levels of kidney function, greater responsiveness to acute changes in parathyroid hormone (PTH), and significantly more urinary phosphate at 2 hours. In humans, increases in urinary phosphate to creatinine ratio did not correlate with baseline serum phosphate concentrations but did correlate strongly to early increase of serum phosphate. The blunted rise in serum phosphate in rats with CKD was not the result of altered absorption. This result suggests acute tissue deposition may be altered in the setting of kidney function impairment. Early recognition of impaired phosphate tolerance could translate to important interventions, such as dietary phosphate restriction or phosphate binders, being initiated at much higher levels of kidney function than is current practice. © 2017 American Society for Bone and Mineral Research. © 2017 American Society for Bone and Mineral Research.

    To develop a population pharmacokinetic model for a new diclofenac suspension (50 mg 5 ml(-1)) in adult volunteers and paediatric patients, and recommend a dose for acute pain in children. Blood samples were drawn at the start and end of surgery, and on removal of the venous cannula from 70 children (aged 1 to 12 years, weight 9 to 37 kg) who received a preoperative oral 1 mg kg(-1) dose; these were pooled with rich (14 post-dose samples) data from 30 adult volunteers. Population pharmacokinetic modelling was undertaken with NONMEM. The optimum adult dose of diclofenac for acute pain is 50 mg. Simulation from the final model was performed to predict a paediatric dose to achieve a similar AUC to 50 mg in adults. A total of 558 serum diclofenac concentrations from 100 subjects was used in the pooled analysis. A single disposition compartment model with first order elimination and dual absorption compartments was used. The estimates of CL/F and V(D)/F were 53.98 l h(-1) 70 kg(-1) and 4.84 l 70 kg(-1) respectively. Allometric size models appeared to predict adequately changes in CL and V(D) with age. Of the simulated doses investigated, 1 mg kg(-1) gave paediatric AUC((0,12 h)) to adult 50 mg AUC((0,12 h)) ratios of 1.00, 1.08 and 1.18 for ages 1-3, 4-6 and 7-12 years respectively. This study has shown 1 mg kg(-1) diclofenac to produce similar exposure in children aged 1 to 12 years as 50 mg in adults, and is acceptable for clinical practice; patients are unlikely to obtain further benefit from higher doses.

    The oral health of older people in acute hospitals has rarely been studied. Hospital admission provides a prime opportunity for identification and rectification of problems, and oral health promotion. This two-part article explores oral hygiene and mouth care provision for older adults in acute hospitals. The first article presents the findings of a literature review exploring oral and dental disease in older adults, the importance of good oral health and mouth care, and the current situation. Searches of electronic databases and the websites of relevant professional health service bodies in the UK were undertaken to identify articles and guidelines. The literature shows a high prevalence of oro-dental disease in this population, with many known detrimental effects, combined with suboptimal oral hygiene and mouth care provision in acute hospitals. Several guidelines exist, although the emphasis on oral health is weaker than other aspects of hospital care. Older adults admitted to acute hospitals have a high burden of oro-dental disease and oral and mouth care needs, but care provision tends to be suboptimal. The literature is growing, but this area is still relatively neglected. Great potential exists to develop oral and mouth care in this context. The second part of this article explores clinical recommendations. ©2012 RCN Publishing Company Ltd. All rights reserved.

    The purpose of this study was to compare efficacy and safety among intramuscular olanzapine, intramuscular haloperidol, orally disintegrating olanzapine tablets, and oral risperidone solution for agitated patients with psychosis during the first 24 hours of treatment in an acute care psychiatric ward. Forty-two inpatients from an acute care psychiatric ward of a medical center in central Taiwan were enrolled. They were randomly assigned to 1 of the 4 treatment groups (10-mg intramuscular olanzapine, 10-mg olanzapine oral disintegrating tablet, 3-mg oral risperidone solution, or 7.5-mg intramuscular haloperidol). Agitation was measured by using the excited component of the Positive and Negative Syndrome Scale (PANSS-EC), the Agitation-Calmness Evaluation Scale, and the Clinical Global Impression--Severity Scale during the first 24 hours. There were significant differences in the PANSS-EC total scores for the 4 intervention groups at 15, 30, 45, 60, 75, and 90 minutes after the initiation of treatment. More significant differences were found early in the treatment. In the post hoc analysis, the patients who received intramuscular olanzapine or orally disintegrating olanzapine tablets showed significantly greater improvement in PANSS-EC scores than did patients who received intramuscular haloperidol at points 15, 30, 45, 60, 75, and 90 minutes after injection. These findings suggest that intramuscular olanzapine, orally disintegrating olanzapine tablets, and oral risperidone solution are as effective treatments as intramuscular haloperidol for patients with acute agitation. Intramuscular olanzapine and disintegrating olanzapine tablets are more effective than intramuscular haloperidol in the early phase of the intervention. There is no significant difference in effectiveness among intramuscular olanzapine, orally disintegrating olanzapine tablets, and oral risperidone solution.

    The relationship between the oral efficacy and the acute toxicity of hydroxypyridin-4-one iron chelators has been investigated to clarify structure-function relationships of these compounds in vivo and to identify compounds with the maximum therapeutic safety margin. By comparing 59Fe excretion following oral or intraperitoneal administration of increasing doses of each chelator to iron-overloaded mice, the most effective compounds have been identified. These have partition coefficients (Kpart) above 0.3 in the iron-free form with a trend of increasing oral efficacy with increasing Kpart values (r = .6). However, this is achieved at a cost of increasing acute toxicity, as shown by a linear correlation between 59Fe excretion increase per unit dose and 1/LD50 (r = .83). A sharp increase in the LD50 values is observed for compounds with Kpart values above 1.0, suggesting that such compounds are unlikely to possess a sufficient therapeutic safety margin. Below a Kpart of 1.0, acute toxicity is relatively independent of lipid solubility. All the compounds are less toxic by the oral route than by the intraperitoneal route, although iron excretion is not significantly different by these two routes. At least five compounds (CP51, CP94, CP93, CP96, and CP21) are more effective orally than the same dose of intraperitoneal desferrioxamine (DFO) (P less than or equal to .02) or orally administered L1(CP20) (P less than or equal to .02)

    Acute hospital admission provides an excellent opportunity to address poor oral health in older people, a group rarely seen by dental professionals and for who oral health activity in hospital is inconsistent and generally suboptimal. This two-part article explores oral hygiene and mouth care provision for older adults in acute hospitals. The first article presented the findings of a literature review exploring oral and dental disease in older adults, the importance of good oral health and mouth care, and the current situation. The second article explores clinical recommendations. A change in philosophy is needed to embed oral care as an essential component of holistic practice. More research is needed to determine the best ways to assess and treat oro-dental problems in older people, and promote and restore their oral health in hospitals. Great potential exists to innovate and develop new ways of providing care to this group. ©2017 RCN Publishing Company Ltd. All rights reserved.

    In order to potentially use sodium caseinate (SC) glycated with galactose (Gal) in the food industry as a new functional ingredient with proved technological and biological properties, an evaluation of oral acute toxicity has been carried out. An acute safety study with SC-Gal glycoconjugates in the Wistar rat with a single oral gavage dose of 2,000 mg/kg of body weight was conducted. The SC-Gal glycoconjugates were well tolerated; no adverse effects or mortality was observed during the 2-week observation period. No abnormal signs, behavioral changes, body weight changes, or alterations in food and water consumption occurred. After this period, no changes in hematological and serum chemistry parameters, organ weights, or gross pathology or histopathology were detected. It was concluded that SC-Gal glycoconjugates obtained via the Maillard reaction were well tolerated in rats at an acute oral dose of 2,000 mg/kg of body weight. The SC-Gal glycoconjugates have a low order of acute toxicity, and the oral 50 % lethal dose for male and female rats is in excess of 2,000 mg/kg of body weight.

    Diclofenac potassium powder for oral solution (Voltfast(®), Catafast(®), Cambia(®); hereafter referred to as diclofenac potassium powder) is a non-steroidal anti-inflammatory drug (NSAID), and is indicated for the acute treatment of migraine. This article reviews the pharmacological properties of diclofenac potassium powder and its efficacy and tolerability in patients with acute migraine. Diclofenac potassium powder was clinically efficacious and generally well tolerated in placebo-controlled trials in patients with this indication; it was more effective than diclofenac potassium tablets with regard to the primary endpoint of 2-h pain relief as well as in several important secondary endpoints, such as time to onset of analgesic action. The oral powder-for-solution formulation of diclofenac potassium is a useful option in the acute treatment of migraine with or without aura.

    Development of an acute oral toxicity test with a terrestrial-phase amphibian was considered necessary to remove the uncertainty within the field of agrochemical risk assessments. The bullfrog (Lithobates catesbeianus) was selected for use as it is a representative of the family Ranidae and historically this species has been used as an amphibian test model species. Prior to definitive study, oral gavage methods were developed with fenthion and tetraethyl pyrophosphate. Dimethoate and malathion were subsequently tested with both male and female juvenile bullfrogs in comprehensive acute oral median lethal dose (LD50) studies. Juvenile bullfrogs were administered a single dose of the test article via oral gavage of a single gelatin capsule of dimethoate technical (dimethoate) or neat liquid Fyfanon ® Technical (synonym malathion), returned to their respective aquaria, and monitored for survival for 14 d. The primary endpoint was mortality, whereas behavioral responses, food consumption, body weight, and snout-vent length (SVL) were used to evaluate indications of sublethal toxicity (secondary endpoints). Acute oral LD50 values (95% fiducial interval) for dimethoate were 1459 (1176-1810, males) and 1528 (1275-1831, females), and for malathion they were 1829 (1480-2259, males) and 1672 (1280-2183, females) mg active substance/kg body weight, respectively. Based on the results of these studies, the methodology for the acute oral gavage administration of test items to terrestrial-phase amphibians was demonstrated as being a practical method of providing data for risk assessments.

Hyperamylasemia after DBE seems to be a rather common condition respectively. The most probable cause seems to be a mechanical straining of the pancreas. We tried to identify patients in a higher risk of acute pancreatitis after DBE. We investigated several laboratory markers before and after DBE (serum cathepsin B, lactoferrin, E-selectin, SPINK 1, procalcitonin, S100 proteins, alfa-1-antitrypsin, hs-CRP, malondialdehyde, serum and urine amylase and serum lipase. Serum amylase and lipase rose significantly with the maximum 4 hours after DBE. Serum cathepsin and procalcitonin decreased significantly 4 hours after DBE compared to healthy controls and patients values before DBE. Either serum amylase or lipase 4 hours after DBE did not correlate with any markers before DBE. There was a trend for an association between the number of push-and-pull cycles and procalcitonin and urine amylase 4 hours after DBE; between procalcitonin and alfa-1-antitrypsin, cathepsin and hs-CRP; and between E-selectin and malondialdehyde 4 hours after DBE. We found no laboratory markers determinative in advance those patients in a higher risk of acute pancreatitis after DBE.

    2014-01-01

    Background This is an updated version of the original Cochrane review published in Issue 2, 2000. Piroxicam is a non-steroidal anti-inflammatory drug (NSAID) with analgesic properties, and is used mainly for treating rheumatic disorders. Some drugs have been directly compared against each other within a trial setting to determine their relative efficacies, whereas other have not. It is possible, however, to compare analgesics indirectly by examining the effectiveness of each drug against placebo when used in similar clinical situations. Objectives To determine the analgesic efficacy and adverse effects of single-dose piroxicam compared with placebo in moderate to severe postoperative pain. To compare the effects of piroxicam with other analgesics. Search methods Published studies were identified from systematic searching of MEDLINE, Biological Abstracts, EMBASE, CENTRAL and the Oxford Pain Relief Database in December 2007. Additional studies were identified from the reference lists of retrieved reports. Selection criteria The following inclusion criteria were used: full journal publication, randomised placebo controlled trial, double-blind design, adult participants, postoperative pain of moderate to severe intensity at the baseline assessment, postoperative administration of oral or intramuscular piroxicam. Data collection and analysis Summed pain intensity and pain relief data were extracted and converted into dichotomous information to yield the number of participants obtaining at least 50% pain relief. This was used to calculate estimates of relative benefit and number-needed-to-treat-to-benefit (NNT) for one participant to obtain at least 50% pain relief. Information was collected on adverse effects and estimates of relative risk and number-needed-to-treat-to-harm (NNH) were calculated. Main results In this update no further studies were found. The original search identified three studies (141 participants) which compared oral piroxicam 20 mg with placebo and

    Amphibians are currently the most threatened and rapidly declining group of vertebrates and this has raised concerns about their potential sensitivity and exposure to plant protection products and other chemicals. Current environmental risk assessment procedures rely on surrogate species (e.g. fish and birds) to cover the risk to aquatic and terrestrial life stages of amphibians, respectively. Whilst a recent meta-analysis has shown that in most cases amphibian aquatic life stages are less sensitive to chemicals than fish, little research has been conducted on the comparative sensitivity of terrestrial amphibian life stages. Therefore, in this paper we address the questions "What is the relative sensitivity of terrestrial amphibian life stages to acute chemical oral exposure when compared with mammals and birds?" and "Are there correlations between oral toxicity data for amphibians and data for mammals or birds?" Identifying a relationship between these data may help to avoid additional vertebrate testing. Acute oral amphibian toxicity data collected from the scientific literature and ecotoxicological databases were compared with toxicity data for mammals and birds. Toxicity data for terrestrial amphibian life stages are generally sparse, as noted in previous reviews. Single-dose oral toxicity data for terrestrial amphibian life stages were available for 26 chemicals and these were positively correlated with LD50 values for mammals, while no correlation was found for birds. Further, the data suggest that oral toxicity to terrestrial amphibian life stages is similar to or lower than that for mammals and birds, with a few exceptions. Thus, mammals or birds are considered adequate toxicity surrogates for use in the assessment of the oral exposure route in amphibians. However, there is a need for further data on a wider range of chemicals to explore the wider applicability of the current analyses and recommendations. Copyright © 2016 Elsevier Inc.

    2018-03-01

    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.

    Diarrhoea causes 15% of under-5 mortality in developing countries. Zinc (Zn) stores in the body are known to be depleted during acute diarrhoea. The aim of this study was to evaluate the efficacy of Zn given with standard treatment to children with acute or moderate diarrhoea. In this quasi-unmasked, parallel-group study, we enrolled children with diarrhoea at El-Dorra Paediatric Hospital, Gaza Strip, occupied Palestinian territory. Inclusion criteria were children with more than three unformed stools in the preceding 24 h, duration of diarrhoea up to 72 h, and ability to accept oral fluids or feeds. Recruited children were assigned equally to either oral rehydration salts (control group) or oral rehydration salts plus Zn sulphate (Zn group; 10 mg for children younger than 6 months; 20 mg for children aged 6 months and older). All treatments were taken orally for 14 days. Primary outcomes were duration and frequency of diarrhoea. Secondary outcomes included changes in bodyweight, drugs side-effects, and episodes of any or severe dehydration. Data were analysed with SPSS. Outcome measures were compared with the Mann-Whitney U-test, student's t test, odds ratio, or χ 2 test. The study was approved by the ministry of health and the Helsinki Committee in the Gaza Strip. Parents of the children provided verbally informed consent before participation. We enrolled 140 children (aged 1-120 months). Duration of diarrhoea in the Zn group was shorter than in the control group (2·34 days in the Zn group vs 7·20 days in the control group; pZinc supplementation added to standard treatment with oral rehydration salts was effective and resulted in good treatment of diarrhoea.

    Full Text Available The honey bee is credited with approximately 85% of the pollinating activity necessary to supply about one-third of the world’s food supply. Well over 50 major crops depend on these insects for pollination. The crops produce more abundantly when honey bees are plentiful. Worker bees are the ones primarily affected by pesticides. Poisoning symptoms can vary depending on the developmental stage of the individual bee, and the kind of chemical employed. The oral toxicity of these insecticides: (phosalone and pirimicarb, acaricide (propargite, insecticide and acaricide (fenpropathrin, fungicides, and bactericides (copper oxychloride and the Bordeaux mixture, were evaluated for the purposes of this research. The results showed that fenpropathrin had high acute oral toxicity (LC50-24h and LC50-48 were 0.54 and 0.3 ppm, respectively. Propargite had 7785 ppm (active ingredient for LC50-24h and 6736 ppm (active ingredient for LC50-48h in honeybees and is therefore, non-toxic to Apis mellifera. On the other hand, copper oxychloride had minimum acute oral toxicity to honeybees (LC50-24h and LC50-48 were 4591.5 and 5407.9 ppm, respectively and was therefore considered non-toxic. Also, the Bordeaux mixture was safe to use around honeybees. Phosalone and primicarb were considered highly and moderately toxic to honeybees, respectively.

    Two acute and subchronic oral toxicity studies were conducted in rats to evaluate safety of a patented preparation of hydrolyzed chicken sternal cartilage (BioCell Collagen II) containing collagen type II, chondroitin sulfate, and hyaluronic acid. In the acute oral toxicity study, five males and five females of Sprague-Dawley rats were administered a single dose of 5000 mg of the test product per kg body weight and observed for 14 days. All animals survived and exhibited normal body weight gain throughout the study. Macroscopic necropsy examination conducted on day 15 revealed no gross pathological lesions in any of the animals. In the subchronic study, Sprague-Dawley rats (40 males, 40 females) were divided into four same-sex groups (10 animals/group). Animals in each group were administered daily either 0, 30, 300 or 1000 mg of the test product per kg of body weight for over 90 days. All animals survived and showed no significant changes in their body weights and histopathology. Although some differences were observed between the treated and control animals in several parameters, they were generally not dose-related or considered to be of toxicological significance. In conclusion, the results from the two oral toxicity studies with male and female young adult rats indicated that the test preparation from hydrolyzed chicken sternal cartilage collagen (BioCell Collagen II) was well tolerated at all four doses tested.

    Polyols, also known as sugar alcohols, are widely used in the formulation of tooth-friendly and reduced-calorie foods. Considering the significant health benefits of polyols in products formulated for human use, there is increased interest in evaluating potential uses in companion animal applications. Erythritol and xylitol are two polyols which are currently widely used in products ranging from reduced-sugar foods to personal care and cosmetics. Published studies have shown that both of these compounds are well-tolerated in rodents. Their toxicity profiles differ when comparing canine safety data. Doses of xylitol as low as 0.15 g/kg-BW in dogs can result in life-threatening hypoglycemia and acute liver failure, whereas erythritol is well-tolerated in dogs with reported No Adverse Effect Levels upwards of 5 g/kg-BW/day in repeat-dose studies. While pivotal studies substantiating the safe use of erythritol in humans have been published, there are limited published studies to support the safe use of erythritol in dogs. Here we present the results of an acute oral and a sub-chronic oral toxicity study in Beagle dogs. Given the potential health benefits of oral products formulated with erythritol and the data presented herein substantiating the safe use in dogs, erythritol can be safely used in products for canines.

    Full Text Available Inflammatory bowel diseases, such as ulcerative colitis, cause significant morbidity and decreased quality of life. The currently available treatments are not effective in all patients, can be expensive and have potential to cause severe side effects. This prompts the need for new treatment modalities. Enoxaparin, a widely used antithrombotic agent, is reported to possess anti-inflammatory properties and therefore we evaluated its therapeutic potential in a mouse model of colitis. Acute colitis was induced in male C57BL/6 mice by administration of dextran sulfate sodium (DSS. Mice were treated once daily with enoxaparin via oral or intraperitoneal administration and monitored for colitis activities. On termination (day 8, colons were collected for macroscopic evaluation and cytokine measurement, and processed for histology and immunohistochemistry. Oral but not intraperitoneal administration of enoxaparin significantly ameliorated DSS-induced colitis. Oral enoxaparin-treated mice retained their body weight and displayed less diarrhea and fecal blood loss compared to the untreated colitis group. Colon weight in enoxaparin-treated mice was significantly lower, indicating reduced inflammation and edema. Histological examination of untreated colitis mice showed a massive loss of crypt architecture and goblet cells, infiltration of immune cells and the presence of edema, while all aspects of this pathology were alleviated by oral enoxaparin. Reduced number of macrophages in the colon of oral enoxaparin-treated mice was accompanied by decreased levels of pro-inflammatory cytokines. Oral enoxaparin significantly reduces the inflammatory pathology associated with DSS-induced colitis in mice and could therefore represent a novel therapeutic option for the management of ulcerative colitis.

    Tolerance of oral food is an important criterion for hospital discharge in patients with acute pancreatitis. Patients who develop oral feeding intolerance have prolonged hospitalisation, use additional healthcare resources, and have impaired quality of life. This study aimed to quantify the incidence of oral feeding intolerance, the effect of confounders, and determine the best predictors of oral feeding intolerance. Clinical studies indexed in three electronic databases (EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials) were reviewed. Incidence and predictor data were meta-analysed and possible confounders were investigated by meta-regression analysis. A total of 22 studies with 2024 patients met the inclusion criteria, 17 of which (with 1550 patients) were suitable for meta-analysis. The incidence of oral feeding intolerance was 16.3%, and was not affected by WHO region, age, sex, or aetiology of acute pancreatitis. Nine of the 22 studies investigated a total of 62 different predictors of oral feeding intolerance. Serum lipase level prior to refeeding, pleural effusions, (peri)pancreatic collections, Ranson score, and Balthazar score were found to be statistically significant in meta-analyses. Oral feeding intolerance affects approximately 1 in 6 patients with acute pancreatitis. Serum lipase levels of more than 2.5 times the upper limit of normal prior to refeeding is a potentially useful threshold to identify patients at high risk of developing oral feeding intolerance.

    Despite the widespread use of Vernonia anthelmintica seeds in traditional medicine, the need to establish the safety of the Vernonia anthelmintica is required to ascertain the safe use of this herbal medicine. The aim of the present study is to establish the acute toxicity profile of different extracts of Vernonia anthelmintica. Hexane and ethanol extract of Vernonia Anthelmintica has been studied for its brine shrimp lethality potential. Water decoction (WDVA), Hexane (HEVA) and Ethanol (EEVA) extracts of Vernonia anthelmintica has also been evaluated for their in-vivo acute oral toxicity in mice by Lorke's method. Phytochemistry of all three extracts was also evaluated for the presence of their secondary metabolites. All three extracts showed the presence of flavonoids and terpenoids, while alkaloids, tannins and fixed oils were present in HEVA and EEVA. Furthermore EEVA also showed presence of carbohydrates and HEVA also showed the presence of cardiac glycosides. Ethanol and hexane extracts of Vernonia anthelmintica showed a positive cytotoxicity in brine shrimp lethality test at 24 hours with LC50 104.16 (224.0-48.05)μg/ml and 216.11μg/ml (378.2-128.7) respectively as compared to standard drug etoposide LC50 7.46μg/ml. The oral LD50 for EEVA, HEVA and WDVA in mice by Lorke's method was greater than 5000mg/kg. The result of brine shrimp lethality test clearly exhibited the presence of bioactive compounds with cytotoxic potential; however seems to be safe for oral use since LD50 was higher than 5000mg/kg and thus safety of acute dosing in vivo practices is justified.

    Background Large clinical trials are lack of data on non‐vitamin K antagonist oral anticoagulants for acute stroke patients. Aim To evaluate the choice of oral anticoagulants at acute hospital discharge in stroke patients with nonvalvular atrial fibrillation and clarify the underlying characteristics potentially affecting that choice using the multicenter Stroke Acute Management with Urgent Risk‐factor Assessment and Improvement‐NVAF registry (ClinicalTrials.gov NCT01581502). Method The study included 1192 acute ischemic stroke/transient ischemic attack patients with nonvalvular atrial fibrillation (527 women, 77·7 ± 9·9 years old) between September 2011 and March 2014, during which three nonvitamin K antagonist oral anticoagulant oral anticoagulants were approved for clinical use. Oral anticoagulant choice at hospital discharge (median 23‐day stay) was assessed. Results Warfarin was chosen for 650 patients, dabigatran for 203, rivaroxaban for 238, and apixaban for 25. Over the three 10‐month observation periods, patients taking warfarin gradually decreased to 46·5% and those taking nonvitamin K antagonist oral anticoagulants increased to 48·0%. As compared with warfarin users, patients taking nonvitamin K antagonist oral anticoagulants included more men, were younger, more frequently had small infarcts, and had lower scores for poststroke CHADS 2, CHA 2 DS 2‐VASc, and HAS‐BLED, admission National Institutes of Health stroke scale, and discharge modified Rankin Scale. Nonvitamin K antagonist oral anticoagulants were started at a median of four‐days after stroke onset without early intracranial hemorrhage. Patients starting nonvitamin K antagonist oral anticoagulants earlier had smaller infarcts and lower scores for the admission National Institutes of Health stroke scale and the discharge modified Rankin Scale than those starting later. Choice of nonvitamin K antagonist oral anticoagulants was independently associated with 20‐day or

    Full Text Available Type 2 diabetes and prediabetes are established risk factors for atherosclerosis. The aim of this study was to evaluate the atherosclerotic plaque burden in the carotid arteries of patients with acute coronary syndrome according to their glycemic status.Patients with acute coronary syndrome and no previous history of type 2 diabetes were consecutively included in the study. Glucose metabolism was evaluated with fasting glucose in plasma, HbA1c and a standard two-hour oral glucose tolerance test. Atherosclerotic plaque in the carotid arteries was evaluated with a standardized ultrasound examination where total plaque area was measured and patients classified as having no plaque or a significant plaque formation.A total of 245 acute coronary syndrome patients (male 78%, 64 years (SD: 10.9 were included. The proportion diagnosed with normal glucose metabolism, prediabetes and type 2 diabetes was 28.6%, 64.1% and 7.3%, respectively. A significant atherosclerotic plaque was found in 48.5%, 66.9% and 72.2% of patients with normal glucose metabolism, prediabetes and type 2 diabetes, respectively. An incremental increase in total plaque area was found from normal glucose metabolism to prediabetes (25.5% and from normal glucose metabolism to type 2 diabetes (35.9% (p = 0.04. When adjusted for conventional cardiovascular risk factors the OR of having significant atherosclerotic plaque in the carotid arteries was 2.17 (95% CI 1.15-4.15 for patients with newly diagnosed dysglycemia compared to patients with normal glucose metabolism. When additionally adjusted for the 2-hour plasma glucose after glucose loading (2hPG the OR attenuated to 1.77 (95% CI 0.83-3.84.Newly detected dysglycemia is an independent predictor of significant atherosclerotic plaque in the carotid arteries with oral glucose tolerance test as a major determinant of carotid plaque burden in this group of individuals with acute coronary syndrome.

    To determine the frequency of manual and oral apraxia in acute stroke and to examine the influence of these symptoms on functional outcome. Seven hundred seventy six unselected, acute stroke patients who were admitted within seven days of stroke onset with unimpaired consciousness were included. If possible, the patients were assessed for manual and oral apraxia on acute admission. Neurologic stroke severity including aphasia was assessed with the Scandinavian Stroke Scale, and activities of daily living function was assessed with the Barthel Index. All patients completed their rehabilitation in the same large stroke unit. Six hundred eighteen patients could cooperate with the apraxia assessments. Manual apraxia was found in 7% of subjects (10% in left and 4% in right hemispheric stroke; chi2 = 9.0; P = 0.003). Oral apraxia was found in 6% (9% in left and 4% in right hemispheric stroke; chi2 = 5.4; P = 0.02). Both manual and oral apraxia were related to increasing stroke severity, and manual, but not oral, apraxia was associated with increasing age. There was no gender difference in frequency of apraxia. Patients with either type of apraxia had temporal lobe involvement more often than patients without. When analyzed with multiple linear and logistic regression analyses, neither manual nor oral apraxia had any independent influence on functional outcome. Apraxia is significantly less frequent in unselected patients with acute stroke than has previously been assumed and has no independent negative influence on functional outcome.

  19. Oral Administration of Astrovirus Capsid Protein Is Sufficient To Induce Acute Diarrhea In Vivo

    2016-11-01

    Full Text Available The disease mechanisms associated with the onset of astrovirus diarrhea are unknown. Unlike other enteric virus infections, astrovirus infection is not associated with an inflammatory response or cellular damage. In vitro studies in differentiated Caco-2 cells demonstrated that human astrovirus serotype 1 (HAstV-1 capsid protein alone disrupts the actin cytoskeleton and tight junction complex, leading to increased epithelial barrier permeability. In this study, we show that oral administration of purified recombinant turkey astrovirus 2 (TAstV-2 capsid protein results in acute diarrhea in a dose- and time-dependent manner in turkey poults. Similarly to that induced by infectious virus, TAstV-2 capsid-induced diarrhea was independent of inflammation or histological changes but was associated with increased intestinal barrier permeability, as well as redistribution of sodium hydrogen exchanger 3 (NHE3 from the membrane to the cytoplasm of the intestinal epithelium. Unlike other viral enterotoxins that have been identified, astrovirus capsid induces diarrhea after oral administration, reproducing the natural route of infection and demonstrating that ingestion of intact noninfectious capsid protein may be sufficient to provoke acute diarrhea. Based on these data, we hypothesize that the astrovirus capsid acts like an enterotoxin and induces intestinal epithelial barrier dysfunction.

    Curcuma longa Linn. (Zingiberaceae) commonly known as turmeric has long been used for centuries as a spice and household remedy. The present study was carried out to assess the possible mutagenic potential and acute oral toxicity of polysaccharide extract of turmeric rhizome (NR-INF-02) using standard tests. The standard battery of in vitro genotoxicity tests, bacterial reverse mutation test (BRMT), chromosome aberration (CA), and micronucleus (MN) tests were employed to assess the possible mutagenic activity of NR-INF-02 (Turmacin). The results showed no mutagenic effect with NR-INF-02 up to a dose of 5000 µg/mL in BRMT. The results on CA and MN tests revealed the non clastogenic activity of NR-INF-02 in a dose range of 250.36 to 2500 µg/mL with and without metabolic activation (S9). In acute oral toxicity study, NR-INF-02 was found to be safe up to 5 g/kg body weight in Wistar rats. Overall, results indicated that polysaccharide extract of C. longa was found to be genotoxically safe and also exhibited maximum tolerable dose of more than 5 g/kg rat body weight. PMID:24455673

    To carry out a preliminary phytochemical, acute oral toxicity and antihepatotoxic study of the roots of Paeonia officinalis (P. officinalis) L. Preliminary phytochemical investigation was done as per standard procedures. Acute oral toxicity study was conducted as per OECD 425 guidelines. The antihepatotoxic activity of aqueous extract of root of P. officinalis was evaluated against carbon tetrachloride (CCl4) induced hepatic damage in rats. Aqueous extract of P. officinalis at the dose levels of 100 and 200 mg/kg body weight was administered daily for 14 d in experimental animals. Liver injury was induced chemically, by CCl4 administration (1 mL/kg i.p.). The hepatoprotective activity was assessed using various biochemical parameters like aspartate aminotransferase (AST), alanine aminotransferase (ALT), serum alkaline phosphatase (SALP), total bilirubin and total protein (TP) along with histopathological studies. Phytochemical screening revealed that the roots of P. officinalis contain alkaloids, tannins, saponins, glycosides, carbohydrates, flavonoids, terpenes, steroids and proteins. The aqueous extract did not cause any mortality up to 2 000 mg/kg. In rats that had received the root extract at the dose of 100 and 200 mg/kg, the substantially elevated AST, ALT, SALP, total bilirubin levels were significantly lowered, respectively, in a dose dependent manner, along with CCl4 while TP levels were elevated in these groups. Histopathology revealed regeneration of the livers in extract treated groups while Silymarin treated rats were almost normal. The aqueous extract of P. officinalis is safe and possesses antihepatotoxic potential.

    Full Text Available Acute and chronic bacterial prostatitis in outpatients is commonly treated with oral fluoroquinolones; however, the worldwide dissemination of multidrug-resistant (MDR Escherichia coli has resulted in therapeutic failures with fluoroquinolones. We reviewed the literature regarding the use of oral fosfomycin in the treatment of acute and chronic prostatitis caused by MDR E. coli. All English-language references on PubMed from 1986 to June 2017, inclusive, were reviewed from the search “fosfomycin prostatitis.” Fosfomycin demonstrates potent in vitro activity against a variety of antimicrobial-resistant E. coli genotypes/phenotypes including ciprofloxacin-resistant, trimethoprim-sulfamethoxazole-resistant, extended-spectrum β-lactamase- (ESBL- producing, and MDR isolates. Fosfomycin attains therapeutic concentrations (≥4 μg/g in uninflamed prostatic tissue and maintains a high prostate/plasma ratio up to 17 hours after oral administration. Oral fosfomycin’s clinical cure rates in the treatment of bacterial prostatitis caused by antimicrobial-resistant E. coli ranged from 50 to 77% with microbiological eradication rates of >50%. An oral regimen of fosfomycin tromethamine of 3 g·q 24 h for one week followed by 3 g·q 48 h for a total treatment duration of 6–12 weeks appeared to be effective. Oral fosfomycin may represent an efficacious and safe treatment for acute and chronic prostatitis caused by MDR E. coli.

    Full Text Available Background Glyburide (also known as glibenclamide is effective in reducing the severity of tissue destruction and improving functional outcome after experimental spinal cord injury in rodents and so has promise as a therapy in humans. There are many important differences between spinal cord injury in experimental animals and in human clinical cases, making it difficult to introduce new therapies into clinical practice. Spinal cord injury is also common in pet dogs and requires new effective therapies, meaning that they can act as a translational model for the human condition while also deriving direct benefits from such research. In this study we investigated the pharmacokinetics and safety of glyburide in dogs with clinical spinal cord injury. Methods We recruited dogs that had incurred an acute thoracolumbar spinal cord injury within the previous 72 h. These had become acutely non-ambulatory on the pelvic limbs and were admitted to our veterinary hospitals to undergo anesthesia, cross sectional diagnostic imaging, and surgical decompression. Oral glyburide was given to each dog at a dose of 75 mcg/kg. In five dogs, we measured blood glucose concentrations for 10 h after a single oral dose. In six dogs, we measured serum glyburide and glucose concentrations for 24 h and estimated pharmacokinetic parameters to estimate a suitable dose for use in a subsequent clinical trial in similarly affected dogs. Results No detrimental effects of glyburide administration were detected in any participating dog. Peak serum concentrations of glyburide were attained at a mean of 13 h after dosing, and mean apparent elimination half-life was approximately 7 h. Observed mean maximum plasma concentration was 31 ng/mL. At the glyburide dose administered there was no observable association between glyburide and glucose concentrations in blood. Discussion Our data suggest that glyburide can be safely administered to dogs that are undergoing anesthesia, imaging and

    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.

    This review is an update of "Single dose oral ketoprofen and dexketoprofen for acute postoperative pain in adults" last updated in Issue 4, 2009. Ketoprofen is a non-selective nonsteroidal anti-inflammatory drug (NSAID) used to treat acute and chronic painful conditions. Dexketoprofen is the (S)-enantiomer, which is believed to confer analgesia. Theoretically dexketoprofen is expected to provide equivalent analgesia to ketoprofen at half the dose, with a consequent reduction in gastrointestinal adverse events. This review is one of a series on oral analgesics for acute postoperative pain. Individual reviews have been brought together in two overviews to provide information about the relative efficacy and harm of the different interventions. To assess the efficacy and safety of single dose oral ketoprofen and oral dexketoprofen compared with placebo for acute postoperative pain, using methods that permit comparison with other analgesics evaluated in the same way, and criteria of efficacy recommended by an in-depth study at the individual patient level. For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase from 2009 to 28 March 2017. We also searched the reference lists of retrieved studies and reviews, and two online clinical trial registries. Randomised, double-blind, placebo-controlled trials of single dose orally administered ketoprofen or dexketoprofen in adults with moderate to severe acute postoperative pain. Two review authors independently considered studies for inclusion in the review, examined issues of study quality and potential bias, and extracted data. For dichotomous outcomes, we calculated risk ratio (RR) and number needed to treat for an additional beneficial outcome (NNT) or harmful outcome (NNH) with 95% confidence intervals (CI) for ketoprofen and dexketoprofen, compared with placebo, where there were sufficient data. We collected information on the number of participants with at least 50

    Summary Tapered oral dexamethasone for acute chest syndrome (ACS) in sickle cell anaemia was studied using a novel ACS assessment tool and investigational biomarkers. Twelve participants were randomized (mean age 17.3 years) before early study termination. Dexamethasone decreased duration of hospitalization for ACS by 20.8 h compared to placebo (P=0.024). Rebound pain occurred in both groups (3 dexamethasone vs. 1 placebo). Overall, dexamethasone decreased the leucocyte activation biomarker, sL-selectin; however, participants with rebound pain had higher sL-selectin within 24 h of treatment (dexamethasone or placebo). This ACS assessment tool was feasibly applied, and sL-selectin is a promising biomarker of ACS therapy. PMID:21848879

    Diosmectite is a clay used to treat children with acute watery diarrhea. However, its effects on stool output reduction, the key outcome for pediatric antidiarrheal drugs, have not been shown. Two parallel, double-blind studies of diosmectite efficacy on stool reduction were conducted in children 1 to 36 months old in Peru (n = 300) and Malaysia (n = 302). Inclusion criteria included 3 or more watery stools per day for less than 72 hours and weight/height ratios of 0.8 or greater. Exclusion criteria were the need for intravenous rehydration, gross blood in stools, fever higher than 39 degrees C, or current treatment with antidiarrheal or antibiotic medications. Rotavirus status was determined. Diosmectite dosage was 6 g/day (children 1-12 months old) or 12 g/day (children 13-36 months old), given for at least 3 days, followed by half doses until complete recovery. Patients were assigned randomly to groups given diosmectite or placebo, in addition to oral rehydration solution (World Health Organization). Children in each study had comparable average ages and weights. The frequencies of rotavirus infection were 22% in Peru and 12% in Malaysia. Similar amounts of oral rehydration solution were given to children in the diosmectite and placebo groups. Stool output was decreased significantly by diosmectite in both studies, especially among rotavirus-positive children. In pooled data, children had a mean stool output of 94.5 +/- 74.4 g/kg of body weight in the diosmectite group versus 104.1 +/- 94.2 g/kg in the placebo group (P = .002). Diarrhea duration was reduced by diosmectite, which was well tolerated. These results show that diosmectite significantly decreased stool output in children with acute watery diarrhea, especially those who were rotavirus-positive.

    Data generated using standardized testing protocols for toxicity studies generally provide reproducible and reliable results for establishing safe levels and formulating risk assessments. The findings of three OECD guideline-type oral toxicity studies of different duration in rats are summarized in this publication; each study evaluated different titanium dioxide (TiO2) particles of varying sizes and surface coatings. Moreover, each study finding demonstrated an absence of any TiO2 -related hazards. To briefly summarize the findings: 1) In a subchronic 90-day study (OECD TG 408), groups of young adult male and female rats were dosed with rutile-type, surface-coated pigment-grade TiO2 test particles (d50 = 145 nm - 21% nanoparticles by particle number criteria) by oral gavage for 90 days. The no-adverse-effect level (NOAEL) for both male and female rats in this study was 1000 mg/kg bw/day, the highest dose tested. The NOAEL was determined based on a lack of TiO2 particle-related adverse effects on any in-life, clinical pathology, or anatomic/microscopic pathology parameters; 2) In a 28-day repeated-dose oral toxicity study (OECD TG 407), groups of young adult male rats were administered daily doses of two rutile-type, uncoated, pigment-grade TiO2 test particles (d50 = 173 nm by number) by daily oral gavage at a dose of 24,000 mg/kg bw/day. There were no adverse effects measured during or following the end of the exposure period; and the NOAEL was determined to be 24,000 mg/kg bw/day; 3) In an acute oral toxicity study (OECD TG 425), female rats were administered a single oral exposure of surface-treated rutile/anatase nanoscale TiO2 particles (d50 = 73 nm by number) with doses up to 5000 mg/kg and evaluated over a 14-day post-exposure period. Under the conditions of this study, the oral LD50 for the test substance was >5000 mg/kg bw. In summary, the results from these three toxicity studies - each with different TiO2 particulate-types, demonstrated an absence of

    Full Text Available Fosfomycin is a new agent to Canada approved for the treatment of acute uncomplicated cystitis (AUC in adult women infected with susceptible isolates of E. coli and Enterococcus faecalis. We reviewed the literature regarding the use of oral fosfomycin for the treatment of AUC. All English-language references from 1975 to October 2015 were reviewed. In Canada, fosfomycin tromethamine is manufactured as Monurol® and is available as a 3-gram single dose sachet. Fosfomycin has a unique chemical structure, inhibiting peptidoglycan synthesis at an earlier site compared to β-lactams with no cross-resistance with other agents. Fosfomycin displays broad-spectrum activity against ESBL-producing, AmpC-producing, carbapenem-non-susceptible, and multidrug-resistant (MDR E. coli. Resistance to fosfomycin in E. coli is rare (100 µg/mL for 48 hours after a single 3-gram oral dose. No dosage adjustments are required in elderly patients, in pregnant patients, or in either renal or hepatic impairment. Fosfomycin demonstrates a favorable safety profile, and clinical trials have demonstrated efficacy in AUC that is comparable to ciprofloxacin, nitrofurantoin, and trimethoprim-sulfamethoxazole. Fosfomycin’s in vitro activity against common uropathogens, including MDR isolates, its favorable safety profile including pregnancy patients, drug interactions, and clinical trials data demonstrating efficacy in AUC, has resulted in Canadian, US, and European guidelines/authorities recommending fosfomycin as a first line agent for the treatment of AUC.

    The aim of this study was to investigate whether early initiation of new oral anticoagulants (NOAC) for acute stroke or transient ischemic attack (TIA) patients with nonvalvular atrial fibrillation (NVAF) are safe. Between March 2011 and September 2012, stroke or TIA patients with NVAF who started NOAC within 2 weeks were enrolled retrospectively. Symptomatic intracerebral hemorrhage (ICH), hemorrhagic transformation (HT) on T2*-weighted MRI, recurrence of stroke or TIA, systemic embolism and any bleeding complications after initiation of NOAC were evaluated. 41 patients (25 males; mean age 76.2 years) started NOAC; of which, 39 (95%) patients had stroke, and 2 (5%) had TIA. The median (interquartile range) interval from onset to treatment with NOAC was 2 (1-6) days. Symptomatic ICH was not observed. HT on initial T2* and new HT on follow-up T2* were 5 (12%) and 11 (31%), but it was asymptomatic. Of 5 patients who had HT on the initial T2*, enlargement of hemorrhage on follow-up T2* (hemorrhagic infarction (HI) Type 1→HI Type 2) was observed in 1 patient, but it was asymptomatic. None of the patients had recurrent stroke or TIA, systemic embolism, and any bleeding complications. The NOAC may be safe in acute stroke or TIA patients with NVAF. A large, prospective study is needed to confirm this. Copyright © 2013 Elsevier B.V. All rights reserved.

    The new heterocyclic derivative LQFM048 (3) (2,4,6-tris ((E)-ethyl 2-cyano-3-(4-hydroxy-3-methoxyphenyl)acrylate)-1,3,5-triazine) was originally designed through the molecular hybridization strategy from Uvinul® T 150 (1) and (E)-ethyl 2-cyano-3-(4hydroxy-3-methoxyphenyl)acrylate (2) sunscreens, using green chemistry approach. This compound was obtained in global yields (80%) and showed an interesting redox potential. In addition, it is thermally stable up to temperatures around 250°C. It was observed that LQFM048 (3) showed a low degradation after 150min of sunlight exposure at 39°C, whereas the extreme radiation conditions induced a considerable photodegradation of the LQFM048 (3), especially when irradiated by VIS and VIS+UVA. During the determination of sun protection factor, LQFM048 (3) showed interesting results, specially as in association with other photoprotective compounds and commercial sunscreen. Additionally, the compound (3) did not promote cytotoxicity for 3T3 fibroblasts. Moreover, it was not able to trigger acute oral systemic toxicity in mice, being classified as a compound with low acute toxicity hazard (2.000mg/kg>LD50compound synthesized using green chemistry approach is promising showing potential to development of a new sunscreen product with advantage of presenting redox potential, indicating antioxidant properties.

    The aim of this study was to evaluate a low-dose CT with oral contrast medium (LDCT) for the diagnosis of acute appendicitis and compare its performance with standard-dose i.v. contrast-enhanced CT (standard CT) according to patients' BMIs. Eighty-six consecutive patients admitted with suspicion of acute appendicitis underwent LDCT (30 mAs), followed by standard CT (180 mAs). Both examinations were reviewed by two experienced radiologists for direct and indirect signs of appendicitis. Clinical and surgical follow-up was considered as the reference standard. Appendicitis was confirmed by surgery in 37 (43%) of the 86 patients. Twenty-nine (34%) patients eventually had an alternative discharge diagnosis to explain their abdominal pain. Clinical and biological follow-up was uneventful in 20 (23%) patients. LDCT and standard CT had the same sensitivity (100%, 33/33) and specificity (98%, 45/46) to diagnose appendicitis in patients with a body mass index (BMI) {>=} 18.5. In slim patients (BMI < 18.5), sensitivity to diagnose appendicitis was 50% (2/4) for LDCT and 100% (4/4) for standard CT, while specificity was identical for both techniques (67%, 2/3). LDCT may play a role in the diagnostic workup of patients with a BMI {>=} 18.5. (orig.)

    Orofacial pain in people with dementia is difficult to detect, and often under-treated. Our aim was to investigate the prevalence of orofacial pain in people with dementia in acute hospitals in the UK. Secondary aims were to examine oral health status and explore associations between orofacial pain and oral health factors. This cross-sectional observational study was carried out in two UK hospitals. Using the Orofacial Pain Scale in Non-Verbal Individuals (OPS-NVI) to identify orofacial pain, 101 participants with dementia, admitted to acute medical wards, were observed for at least 3 min during rest and chewing. Verbal participants were then asked about presence of orofacial pain, using self-report pain scales. Finally, a brief oral assessment was performed. Orofacial pain, assessed with the OPS-NVI, was present in 11.9% (95% C.I. 5.9, 18.8) of participants at rest and 21.9% (95% C.I. 14.6, 31.3) whilst chewing. Participants who were no longer able to self-report pain were significantly more likely to experience orofacial pain. Oral health in both dentate and edentate participants was poor. Brush frequency, indication of chewing quality, consistency of the food, presence of extra-oral abnormalities, person who performed mouth care, and oral hygiene in dentate participants were significant predictors for the presence of orofacial pain. Improving oral care in acute hospital patients with dementia, particularly those who cannot self-report pain, may significantly reduce pain and suffering in this population.

    Acute respiratory tract infections (ARTIs) are common in children and can involve both upper and lower airways. Many children experience frequent ARTI episodes or recurrent respiratory tract infections (RRTIs) in early life, which creates challenges for paediatricians, primary care physicians, parents and carers of children.In China, Astragalus (Huang qi), alone or in combination with other herbs, is used by Traditional Chinese Medicine (TCM) practitioners in the form of a water extract, to reduce the risk of ARTIs; it is believed to stimulate the immune system. Better understanding of the therapeutic mechanisms of Astragalus may provide insights into ARTI prevention, and consequently reduced antibiotic use. To assess the effectiveness and safety of oral Astragalus for preventing frequent episodes of acute respiratory tract infections (ARTIs) in children in community settings. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 12, 2015), MEDLINE (Ovid) (1946 to 31 December 2015), Embase (Elsevier) (1974 to 31 December 2015), AMED (Ovid) (1985 to 31 December 2015), Chinese National Knowledge Infrastructure (CNKI) (1979 to 31 December 2015) and Chinese Scientific Journals full text database (CQVIP) (1989 to 31 December 2015), China Biology Medicine disc (CBM 1976 to 31 December 2015) and Wanfang Data Knowledge Service Platform (WanFang) (1998 to 31 December 2015). We included randomised controlled trials (RCTs) comparing oral Astragalus as a sole Chinese herbal preparation with placebo to prevent frequent episodes of ARTIs in children. We used standard Cochrane methodological procedures for this review. We assessed search results to identify relevant studies. We planned to extract data using standardised forms. Disagreements were to be resolved through discussion. Risk of bias was to be assessed using the Cochrane 'Risk of bias' tool. We planned to use mean difference (MD) or standardised mean difference (SMD) for continuous data and risk

    Full Text Available Introduction: Acute myeloid leukemia (AML in elderly patients differs biologically from that in younger patients and is known to have unfavorable chromosomal rearrangements, higher resistance, and lower tolerance to chemotherapy. In such circumstances, instead of giving full-blown chemotherapy, palliative metronomic chemotherapy (MCT could be a treatment option. Patients and Methods: We performed a prospective pilot study of old AML patients (age >60 years not amenable to curative treatment. Thirty-two patients were enrolled into the study and were treated with daily oral 6-mercaptopurine 75 mg/m 2 . The following inclusion criteria were used: age >60 years, nonpromyelocytic AML, the absence of uncontrolled comorbidities, and patient not amenable to curative treatment. Overall survival (OS was calculated using Kaplan-Meier method and Cox regression analysis were used to calculate the hazards ratio of significant factors. Results: The median age of the patients was 69 years (range: 61-86 years with male: female ratio of 2.5:1. About 59.4% of patients had Eastern Cooperative Oncology Group performance status of 2 while rest had the status of 3. The median OS was 6 months (95% confidence interval [CI]: 4.4-7.6. Males had median OS of 7 months (95% CI: 5.4-8.6 versus females with OS of 3 months (95% CI: 1.5-4.4; P = 0.008. There was no survival difference on the basis of baseline hemoglobin or French-American-British class. There were no Grade 4 toxicities and no episode of febrile neutropenia. Conclusions: MCT with oral 6-mercaptopurine is an attractive treatment option in elderly AML patients who are not amenable to curative therapy with minimal toxicities.

    Combining two different analgesics in fixed doses in a single tablet can provide better pain relief than either drug alone in acute pain. This appears to be broadly true across a range of different drug combinations, in postoperative pain and migraine headache. A new combination of dexketoprofen (a nonsteroidal anti-inflammatory drug) plus tramadol (an opioid) has been tested in acute postoperative pain conditions. It is not yet licensed for use. This review is one of a series on oral analgesics for acute postoperative pain. Individual reviews have been brought together in two overviews to provide information about the relative efficacy and harm of the different interventions. To assess the analgesic efficacy and adverse effects of a single fixed-dose of oral dexketoprofen plus tramadol, compared with placebo, for moderate to severe postoperative pain in adults, using methods that permit comparison with other analgesics evaluated in standardised trials using almost identical methods and outcomes. A secondary objective was to compare the combination with the individual analgesics alone. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via CRSO, MEDLINE via Ovid, and Embase via Ovid from inception to 31 May 2016. We also searched the reference lists of retrieved studies and reviews, and two online clinical trial registries. Randomised, double-blind trials of oral dexketoprofen plus tramadol administered as a single oral dose, for the relief of acute postoperative pain in adults, and compared to placebo. Two review authors independently considered trials for inclusion in the review, examined issues of study quality and potential bias, and extracted data. For dichotomous outcomes, we calculated risk ratio (RR) and number needed to treat for an additional beneficial outcome (NNT) for dexketoprofen plus tramadol, compared with placebo with 95% confidence intervals (CI). We collected information on the number of participants with at least 50% of

    Ketoprofen is a non-selective non-steroidal anti-inflammatory drug (NSAID) used to treat acute and chronic painful conditions. Dexketoprofen is the (S)-enantiomer, which is believed to confer analgesia. Theoretically dexketoprofen is expected to provide equivalent analgesia to ketoprofen at half the dose, with a consequent reduction in gastrointestinal adverse events. To assess efficacy, duration of action, and associated adverse events of single dose oral ketoprofen and dexketoprofen in acute postoperative pain in adults. We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to August 2009. Randomised, double blind, placebo-controlled trials of single dose orally administered ketoprofen and dexketoprofen in adults with moderate to severe acute postoperative pain. Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk and number-needed-to-treat-to-benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals was collected. Fourteen studies compared ketoprofen (968 participants) at mainly 25 mg and 50 mg with placebo (520 participants). Seven studies compared dexketoprofen (681 participants) at mainly 10 mg to 25 mg with placebo (289 participants). Studies were of adequate reporting quality, and participants had pain following dental, orthopaedic, obstetric, gynaecological and general surgery. There was considerable clinical heterogeneity between studies in dental and other types of surgery, particularly bunionectomy, which limited analysis.Ketoprofen at doses between 12.5 mg and 100 mg produced NNTs for at least 50% pain relief over 4 to 6

  1. Isocitrate dehydrogenase mutation hot spots in acute lymphoblastic leukemia and oral cancer

    Full Text Available Isocitrate dehydrogenase (IDH encodes a nicotinamide adenine dinucleotide phosphate+-dependent enzyme for oxidative decarboxylation of isocitrate and has an essential role in the tricarboxylic acid cycle. Mutations of IDH1 and IDH2 have been identified in patients with glioma, leukemia, and other cancers. However, the incidence of IDH mutations in acute myeloid leukemia in Taiwan is much lower than that reported in Western countries. The reason for the difference is unknown and its clinical implications remain unclear. Acute lymphoblastic leukemia (ALL is a heterogenous hematopoietic malignancy. Oral squamous cell carcinoma (OSCC results from chronic carcinogen exposures and is highly prevalent in trucking workers, especially in southern Taiwan. Subtypes of both diseases require specific treatments, and molecular markers for developing tailored treatments are limited. High-resolution melting (HRM analysis is now a widely used methodology for rapid, accurate, and low-cost mutation scanning. In this study, 90 adults with OSC and 31 children with ALL were scanned by HRM analysis for IDH1 and IDH2 mutation hot spots. In ALL, the allele frequency was 3.23% in both IDH1 and IDH2. In OSCC, the allele frequency was 2.22% in IDH2. A synonymous mutation over pG313 (c.939A > G of IDH2 was found in both pediatric ALL and adult OSCC. Therefore, we concluded that mutations of IDH are uncommon in ALL and OSCC and are apparently not a major consideration when selecting treatment modalities.

    Background Acute diarrhoea is one of the main causes of morbidity and mortality among children in low-income countries. Glucose-based oral rehydration solution (ORS) helps replace fluid and prevent further dehydration from acute diarrhoea. Since 2004, the World Health Organization (WHO) has recommended the osmolarity of less than 270 mOsm/L (ORS ≤ 270) versus greater than 310 mOsm/L formulation (ORS ≥ 310). Polymer-based ORS (for example, prepared using rice or wheat) slowly releases glucose and may be superior to glucose-based ORS. Objectives To compare polymer-based oral rehydration solution (polymer-based ORS) with glucose-based oral rehydration solution (glucose-based ORS) for treating acute watery diarrhoea. Search methods We searched the following sources up to 5 September 2016: the Cochrane Infectious Diseases Group (CIDG) Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 9), MEDLINE (1966 to 5 September 2016), EMBASE (1974 to 5 September 2016), LILACS (1982 to 5 September 2016), and mRCT (2007 to 5 September 2016). We also contacted researchers, organizations, and pharmaceutical companies, and searched reference lists. Selection criteria We included randomized controlled trials (RCTs) of people with acute watery diarrhoea (cholera and non-cholera associated) that compared polymer-based and glucose-based ORS (with identical electrolyte contents). Data collection and analysis Two review authors independently assessed the search results and risk of bias, and extracted data. In multiple-treatment arms with two or more treatment groups, we combined outcomes as appropriate and compared collectively with the control group. Main results Thirty-five trials that included 4284 participants met the inclusion criteria: 28 trials exclusively included children, five included adults, and two included both adults and children. Polymer-based ORS versus glucose-based ORS (osmolarity ≤ 270) Eight trials

    Purpose:To investigate whether a predictive estimate can be obtained for a 'tolerance level' of acute oral and pharyngeal mucosal reactions in patients receiving head and neck radiotherapy, using an objective set of dose and time data. Materials and methods:Several dozen radiotherapy schedules for treating head and neck cancer have been reviewed, together with published estimates of whether they were tolerated or (in a number of schedules) not. Those closest to the borderline were given detailed analysis. Total doses and biologically effective doses (BED or ERD) were calculated for a range of starting times of cellular repopulation and rates of daily proliferation. Starting times of proliferation from 5 to 10 days and daily cellular doubling rates of 1-3 days were considered. The standard published form of BED with its linear overall time factor was used: BED=nd1+((d)/(α/β))-((Ln2T-T k )/(αT p )) (see text for parameters). Results: A clear progression from acceptable to intolerable mucosal reactions was found, which correlated with total biologically effective dose (BED in our published modeling), for all the head and neck cancer radiotherapy schedules available for study, when ranked into categories of 'intolerable' or 'tolerable'. A review of published mechanisms for mucosal reactions suggested that practical schedules used for treatment caused stimulated compensatory proliferation to start at about 7 days. The starting time of compensatory proliferation had little predictive value in our listing, so we chose the starting time of 7 days. Very short and very long daily doubling rates also had little reliability, so we suggest choosing a doubling time of 2.5 days as a datum. With these parameters a 'tolerance zone of uncertainty' could be identified which predicted acute-reaction acceptability or not of a schedule within a range of about 2-10 Gy in total BED. If concurrent chemoradiotherapy is used, our provisional suggestion is that this zone should be reduced

    We report a case of severe oral infection with a high fever due to Lactobacillus rhamnosus during induction chemotherapy for acute myeloid leukemia. The patient did not improve on treatment with meropenem, clindamycin, or vancomycin until neutrophil recovery. Since L. rhamnosus GG is used in dairy products, and the patient ingested dairy products daily before starting chemotherapy, we suspected an association between the ingestion of dairy products and the development of infection. Pulsed-field gel electrophoresis using two different restriction enzymes showed that the strain isolated from the patient was identical to the L. rhamnosus GG strain isolated from dairy products and ATCC #53103. This was confirmed by a PCR assay with species-specific L. rhamnosus GG primers. Since Lactobacillus infection, particularly L. rhamnosus infection, can be fatal in immunocompromised hosts, we should consider Lactobacillus as a causative organism when Gram-positive rods are detected during treatment with broad-spectrum antibiotics and vancomycin. The causal association between the ingestion of dairy products containing Lactobacillus and Lactobacillus infection in immunocompromised hosts warrants further study.

    Background Migraine is a highly disabling condition for the individual and also has wide-reaching implications for society, healthcare services, and the economy. Sumatriptan is an abortive medication for migraine attacks, belonging to the triptan family. Objectives To determine the efficacy and tolerability of oral sumatriptan compared to placebo and other active interventions in the treatment of acute migraine attacks in adults. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, online databases, and reference lists for studies through 13 October 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using oral sumatriptan to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Sixty-one studies (37,250 participants) compared oral sumatriptan with placebo or an active comparator. Most of the data were for the 50 mg and 100 mg doses. Sumatriptan surpassed placebo for all efficacy outcomes. For sumatriptan 50 mg versus placebo the NNTs were 6.1, 7.5, and 4.0 for pain-free at two hours and headache relief at one and two hours, respectively. NNTs for sustained pain-free and sustained headache relief during the 24 hours postdose were 9.5 and 6.0, respectively. For sumatriptan 100 mg versus placebo the NNTs were 4.7, 6.8, 3.5, 6.5, and 5.2, respectively, for the same outcomes. Results for the 25 mg dose were similar to the 50 mg dose, while sumatriptan 100 mg was significantly better than 50 mg for pain-free and headache relief at two hours, and for sustained pain-free during 24 hours.

    Acute rhinosinusitis arises as a consequence of viral rhinitis, and bacterial infection can subsequently occur. Intranasal antibiotics as an adjunct to corticosteroids usually demonstrate the greatest symptom relief. We wanted to clinically evaluate the effects of a topical antibiotic and steroid combination administered intranasally, versus an oral antibiotic alone when treating acute rhinosinusitis. Forty patients with acute bacterial rhinosinusitis were divided into two groups. Group A received an antibiotic and steroid combination (ofloxacin 0.26 per cent and dexamethasone 0.053 per cent nasal drops) for 10 days, administered intranasally (5 drops in each nostril/8 hours). Group B, the control group, received an oral antibiotic alone (amoxicillin 90 mg/kg). Eight hours after commencing treatment, facial pain was more severe in group B and nasal obstruction was reduced in both groups. Ten days after commencing treatment, anterior nasal discharge was 0.15 per cent in group A and absent in group B. The application of a topical antibiotic and steroid combination into the nasal cavity is an effective way of treating uncomplicated, acute bacterial rhinosinusitis with the theoretical advantages of easy administration, high local drug concentration and minimal systemic adverse effects.

    It is now well documented that postnatal exposure to certain chemicals has been reported to increase the risk of autism spectrum disorder. Propionic acid (PA), as a metabolic product of gut microbiotaandas a commonly used food additive, has been reported to mediate the effects of autism. Results from animal studies may help to identify environmental neurotoxic agents and drugs that can ameliorate neurotoxicity and may thereby aid in the treatment of autism. The present study investigated the ameliorative effects of natural bee pollen against acute and sub-acute brain intoxication induced by (PA) in rats. Twenty-four young male Western Albino ratswere enrolled in the present study. They were classified into four equal groups, eachwith6 rats. The control group received only phosphate buffered saline; the oral buffered PA-treated groups (II and III) received a neurotoxic dose of 750 mg/kg body weight divided in 3 dose of 250 mg/kg body weight/day serving asthe acute group and 750 mg/kg body weight divided in 10 equal dose of 75 mg/kg body weight/day as the sub-acute group. The fourth group received 50 mg bee pollen for 30 days after PA-acute intoxication. The obtained data showed that the PA-treated groups demonstrated multiple signs of brain toxicity, as indicated by a depletion of serotonin (5HT), dopamine and nor-adrenaline, together withan increase in IFN-γ and caspase 3. Bee pollen was effective in ameliorating the neurotoxic effect of PA. All measured parameters demonstrated minimal alteration in comparison with thecontrol animal than did those of acute and sub-acute PA-treated animals. In conclusion, bee pollen demonstrates anti-inflammatory and anti-apoptotic effects while ameliorating the impaired neurochemistry of PA-intoxicated rats.

    Antibodies targeting IL-17A or its receptor, IL-17RA, are approved to treat psoriasis and are being evaluated for other autoimmune conditions. Conversely, IL-17 signaling is critical for immunity to opportunistic mucosal infections caused by the commensal fungus Candida albicans, as mice and humans lacking the IL-17R experience chronic mucosal candidiasis. IL-17A, IL-17F, and IL-17AF bind the IL-17RA-IL-17RC heterodimeric complex and deliver qualitatively similar signals through the adaptor Act1. Here, we used a mouse model of acute oropharyngeal candidiasis to assess the impact of blocking IL-17 family cytokines compared with specific IL-17 cytokine gene knockout mice. Anti-IL-17A antibodies, which neutralize IL-17A and IL-17AF, caused elevated oral fungal loads, whereas anti-IL-17AF and anti-IL-17F antibodies did not. Notably, there was a cooperative effect of blocking IL-17A, IL-17AF, and IL-17F together. Termination of anti-IL-17A treatment was associated with rapid C. albicans clearance. IL-17F-deficient mice were fully resistant to oropharyngeal candidiasis, consistent with antibody blockade. However, IL-17A-deficient mice had lower fungal burdens than anti-IL-17A-treated mice. Act1-deficient mice were much more susceptible to oropharyngeal candidiasis than anti-IL-17A antibody-treated mice, yet anti-IL-17A and anti-IL-17RA treatment caused equivalent susceptibilities. Based on microarray analyses of the oral mucosa during infection, only a limited number of genes were associated with oropharyngeal candidiasis susceptibility. In sum, we conclude that IL-17A is the main cytokine mediator of immunity in murine oropharyngeal candidiasis, but a cooperative relationship among IL-17A, IL-17AF, and IL-17F exists in vivo. Susceptibility displays the following hierarchy: IL-17RA- or Act1-deficiency > anti-IL-17A + anti-IL-17F antibodies > anti-IL-17A or anti-IL-17RA antibodies > IL-17A deficiency. © Society for Leukocyte Biology.

    Full Text Available Methylphenidate (MPD is a commonly administered drug to treat children suffering from attention deficit hyperactivity disorder (ADHD. Alterations in septal driven hippocampal theta rhythm may underlie attention deficits observed in these patients. Amongst others, the septo-hippocampal connections have long been acknowledged to be important in preserving hippocampal function. Thus, we wanted to ascertain if methylphenidate administration, which improves attention in patients, could affect septal areas connecting with hippocampus. We used low and orally administered methylphenidate doses (1.3; 2.7 and 5mg/Kg to rats what mimics the dosage range in humans. In our model, we observed no effect when using 1.3mg/Kg methylphenidate; whereas 2.7 and 5 mg/Kg induced a significant increase in c-fos expression specifically in the medial septum, an area intimately connected to the hippocampus. We analyzed dopaminergic areas such as nucleus accumbens and striatum, and found that only 5mg/Kg induced c-fos levels increase. In these areas tyrosine hydroxylase correlated well with c-fos staining, whereas in the medial septum the sparse tyrosine hydroxylase fibres did not overlap with c-fos positive neurons. Double immunofluorescence of c-fos with neuronal markers in the septal area revealed that co-localization with choline acethyl transferase, parvalbumin, and calbindin with c-fos did not change with MPD treatment; whereas, calretinin and c-fos double labeled neurons increased after MPD administration. Altogether, these results suggest that low and acute doses of methylphenidate primary target specific populations of caltretinin medial septal neurons.

    Combining two different analgesics in fixed doses in a single tablet can provide better pain relief than either drug alone in acute pain. This appears to be broadly true across a range of different drug combinations, in postoperative pain and migraine headache. Some combinations of ibuprofen and paracetamol are available for use without prescription in some acute pain situations. To assess the efficacy and adverse effects of single dose oral ibuprofen plus paracetamol for acute postoperative pain using methods that permit comparison with other analgesics evaluated in standardised trials using almost identical methods and outcomes. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (Issue 4 of 12, 2013), MEDLINE (1950 to May 21st 2013), EMBASE (1974 to May 21st 2013), the Oxford Pain Database, ClinicalTrials.gov, and reference lists of articles. Randomised, double-blind clinical trials of single dose, oral ibuprofen plus paracetamol compared with placebo or the same dose of ibuprofen alone for acute postoperative pain in adults. Two review authors independently considered trials for inclusion in the review, assessed quality, and extracted data. We used validated equations to calculate the area under the pain relief versus time curve and derive the proportion of participants with at least 50% of maximum pain relief over six hours. We calculated relative risk (RR) and number needed to treat to benefit (NNT) for ibuprofen plus paracetamol, ibuprofen alone, or placebo. We used information on use of rescue medication to calculate the proportion of participants requiring rescue medication and the weighted mean of the median time to use. We also collected information on adverse events. Searches identified three studies involving 1647 participants. Each of them examined several dose combinations. Included studies provided data from 508 participants for the comparison of ibuprofen 200 mg + paracetamol 500 mg with placebo, 543

    Full Text Available Context: Sacha Inchi has been consumed for years by indigenous peoples. Meanwhile, its toxicological potential has not been sufficiently studied. Aims: To assess the acute, sub-chronic toxicity and genotoxicity evaluation of Sacha Inchi powder obtained from Plukenetia volubilis L. Methods: A dose of 2000 mg/kg was orally administered to rats and mice and toxicity symptoms for 14 days were observed. In repeated dose study, the product was orally administered to Sprague Dawley rats of both sexes. Animals received 50, 250 and 500 mg/kg/day of the product for 90 days. At the end, animals were sacrificed and samples were done for hematological and biochemical analysis, organ weighs and histopathological examination. Genotoxicity potential of Sacha Inchi powder was evaluated through micronucleus test in mice. Negative controls received the vehicle (carboxymethyl cellulose, 0.5% used. Results: No morbidity or mortality at 2000 mg/kg of the product were found. Sacha Inchi powder oral administration during 90 days to rats did not lead to death, body weight gain, food consumption, or adverse events. No significant changes on hematological or biochemical parameters, organ weights or histopathological findings were observed. Induction of micronucleus formation attributable to the product was not found in mice. Conclusions: No toxicity effects after oral acute exposure of Sacha Inchi power to rats and mice were observed. Neither toxicity attributable to oral doses of the product up to 500 mg/kg during 90 days to rats were found. Results suggested Sacha Inchi powder does not have genotoxicity potential under our experimental conditions.

    The effects of the organophosphate insecticide chlorpyrifos on 5min open-field activity were examined in a 7-15 days old chick model. Chlorpyrifos was acutely administered taking into account cholinesterase inhibition and determination of the acute (24h) median lethal dose (LD50). The oral LD50 value of chlorpyrifos in chicks was 18.14mg/kg, with cholinergic toxicosis observed on intoxicated chicks. Chlorpyrifos at the dose rates of 5,10 and 20mg/kg orally produced within 2h signs of cholinergic toxicosis in the chicks and significantly inhibited plasma (40-70%), whole brain (43-69%) and liver (31-46%) cholinesterase activities in a dose-dependent manner. Chlorpyrifos at 2 and 4mg/kg, orally did not produce overt signs of cholinergic toxicosis, but decreased (30, 60 and 90min after dosing) the general locomotor activity of the chicks as seen by a significant increase in the latency to move from the central square of the open-field arena, decreases in the numbers of lines crossed and vocalization score. Repeated daily chlorpyrifos treatments (2 and 4mg/kg, orally) for seven consecutive days also caused hypoactivity in chicks in the open-field behavioral paradigm. Only the high dose of chlorpyrifos (4mg/kg, orally) given repeatedly for 7 days caused significant cholinesterase inhibition in the whole brain (37%) and the liver (22%). In conclusion, chlorpyrifos at single or short-term repeated doses-induced behavioral changes in 7-15 days old chicks, in a model that could be used for further neurobehavioral studies involving subtle effects of organophosphates on chicks.

    To investigate risk factors for acute oral mucosal reaction during head and neck squamous cell carcinoma radiotherapy.A retrospective study of patients with head and neck squamous cell carcinoma who underwent radiotherapy from November 2013 to May 2016 in Anhui Provincial Cancer Hospital was conducted. Data on the occurrence and severity of acute oral mucositis were extracted from clinical records. Based on the Radiation Therapy Oncology Group (RTOG) grading of acute radiation mucosal injury, the patients were assigned into acute reaction (grades 2-4) and minimum reaction (grades 0-1) groups. Preradiotherapy characteristics and treatment factors were compared between the 2 groups. Multivariate logistic regression analysis was used to detect the independent factors associated with acute oral mucosal reactions.Eighty patients completed radiotherapy during the study period. Oral mucosal reactions were recorded as 25, 31, and 24 cases of grades 1, 2, and 3 injuries, respectively. Significant differences between acute reaction and minimum reaction groups were detected in cancer lymph node (N) staging, smoking and diabetes history, pretreatment platelet count and T-Helper/T-Suppressor lymphocyte (Th/Ts) ratio, concurrent chemotherapy, and total and single irradiation doses.Multivariate analysis showed that N stage, smoking history, single dose parapharyngeal irradiation, and pretreatment platelet count were independent risk factors for acute radiation induced oral mucosal reaction. Smoking history, higher grading of N stage, higher single dose irradiation, and lower preirradiation platelet count may increase the risk and severity of acute radiation oral mucosal reaction in radiotherapy of head and neck cancer patients.

    Oral rehydration therapy (ORT) remains the ideal first line therapy for acute gastroenteritis (AGE). Our aim was to assess the impact of introducing an Oral Fluid Challenge (OFC) protocol on outcomes such as intravenous fluid use and documentation in our institution. A single centre study with data collected retrospectively pre-implementation (April 2015) of the OFC protocol and post implementation (April 2016). Consecutive sampling of the first 55 patients presenting with GE like symptoms and underwent OFC were recruited. One hundred and ten patients were included in this study with 55 patients per cycle. The rates of IVF use decreased from 22% (12) in cycle one to 18% (10) in cycle two. There was an improvement in documentation by 26% (14) for level of dehydration and 52% (31) for OFC volume from cycle one to two. Overall, the addition of the OFC protocol to the management of patients with uncomplicated AGE would help streamline and improve care.

    Purpose: Acute rectal complications occur in the majority of patients receiving external-beam radiotherapy for carcinoma of the prostate. Sucralfate has been proposed to reduce radiation-induced mucosal injury by forming a protective barrier on ulcer bases, binding local growth factors, and stimulating angiogenesis. However, there is conflicting clinical evidence as to whether sucralfate, taken prophylactically during radiotherapy, can ameliorate the symptoms of acute radiation proctitis. Methods and Materials: A double-blind randomized trial was conducted at four Radiation Oncology Departments in Sydney, Australia, between February 1995 and June 1997. A total of 338 patients with clinically localized prostate cancer receiving small volume radiotherapy, of whom 335 were evaluable, were randomized to receive either 3 g of oral sucralfate suspension or placebo twice a day during radiotherapy. Patients kept a daily record of their bowel symptoms and were graded according to the RTOG/EORTC acute toxicity criteria. Results: One hundred sixty-four patients received sucralfate and 171 received placebo. Both groups were well balanced with regard to patient, tumor, treatment factors, and baseline symptoms, except that the placebo group had a significantly more liquid baseline stool consistency score (p=0.004). Patients kept a daily diary of symptoms during radiotherapy. After adjusting for baseline values, there was no significant difference between the two groups with regard to stool frequency (p=0.41), consistency (p=0.20), flatus (p=0.25), mucus (p=0.54), and pain (p=0.73). However, there was more bleeding in the sucralfate group, with 64% of patients noticing rectal bleeding, compared with 47% in the placebo group (p=0.001). There was no significant difference between the two groups with respect to RTOG/EORTC acute toxicity (p=0.88; sucralfate 13%, 44%, 43% and placebo 15%, 44%, 40% for grade 0, 1, and 2, respectively). Conclusion: This study suggests that oral

    Neutrophil numbers and function (oxidative burst) were assessed in peripheral blood and oral samples before and after prolonged exercise. Blood neutrophil count increased (∼3.5-fold, P < 0.001) and function decreased (30% ± 19% decrease, P = 0.005) postexercise. Oral neutrophil count (P = 0.392) and function (P = 0.334) were unchanged. Agreement between oral and blood neutrophil function responses to exercise was poor. These findings highlight the importance of studying neutrophils within various compartments/sample types.

    Full Text Available A disfonia aguda é um quadro comum na prática clínica. Seu tratamento, principalmente em adultos, não é bem definido na literatura. O corticoide é o tratamento medicamentoso mais recomendado. Os estudos existentes, entretanto, não são suficientes para a determinação da superioridade entre diferentes corticoides e a melhor forma de administração. OBJETIVO: Este estudo clínico prospectivo teve como objetivo comparar o efeito do corticoide inalatório na forma de pó seco com o efeito do corticoide oral, no tratamento da disfonia aguda. MÉTODO: Foram avaliados 32 pacientes adultos, divididos em dois grupos de 16 pacientes para cada um dos tratamentos, antes e após sete dias do uso da medicação. Os pacientes foram submetidos à videolaringosocpia e avaliação perceptiva e acústica da voz. RESULTADOS: O tratamento inalatório e oral reduziram significativamente a hiperemia, o edema e melhorou o movimento muco-ondulatório; entretanto, a redução do edema foi estatisticamente mais significativa (p = 0,012 nos pacientes tratados com a forma inalatória. A comparação dos valores da análise perceptiva auditiva e das medidas acústicas após tratamento entre os grupos, entretanto, não apresentou significância estatística. CONCLUSÃO: Houve melhora significativa da laringite aguda nas avaliações realizadas, em todos os pacientes estudados, com os dois tratamentos. O tratamento com corticoide inalatório foi significativamente mais efetivo na redução do edema.Acute dysphonia is a frequent condition in clinical practice.

    To determine whether oral administration of 3% hypertonic saline (HTS) is as efficacious as intravenous (IV) 3% saline in reversing symptoms of mild-to-moderate symptomatic exercise-associated hyponatremia (EAH) in athletes during and after a long-distance triathlon. Noninferiority, open-label, parallel-group, randomized control trial to IV or oral HTS. We used permuted block randomization with sealed envelopes, containing the word either "oral" or "IV." Annual long-distance triathlon (3.8-km swim, 180-km bike, and 42-km run) at Mont-Tremblant, Quebec, Canada. Twenty race finishers with mild to moderately symptomatic EAH. Age, sex, race finish time, and 9 clinical symptoms. Time from treatment to discharge. We successfully randomized 20 participants to receive either an oral (n = 11) or IV (n = 9) bolus of HTS. We performed venipuncture to measure serum sodium (Na) at presentation to the medical clinic and at time of symptom resolution after the intervention. The average time from treatment to discharge was 75.8 minutes (SD 29.7) for the IV treatment group and 50.3 minutes (SD 26.8) for the oral treatment group (t test, P = 0.02). Serum Na before and after treatment was not significantly different in both groups. There was no difference on presentation between groups in age, sex, or race finish time, both groups presented with an average of 6 symptoms. Oral HTS is effective in reversing symptoms of mild-to-moderate hyponatremia in EAH.

    Pain management and welfare are increasingly prevalent concerns within animal agriculture. Analgesics may alleviate pain and inflammation associated with castration of beef cattle. This study was conducted to elucidate the effects of surgical castration on the acute inflammatory response and immunomodulation and whether concurrent oral administration of meloxicam (1 mg/kg BW) would alter these responses. On d -1, crossbred bull calves ( = 30; initial BW = 227.4 ± 10.3 kg) were fitted with indwelling jugular catheters and rectal temperature (RT) recording devices, placed into individual stanchions, and randomly assigned to 1 of 3 treatments. Treatment application occurred at h 0 and consisted of 1) intact bull calves treated with sham castration (CON), 2) bulls surgically castrated without meloxicam administration (CAS), and 3) bulls surgically castrated with oral meloxicam (1 mg/kg BW) administration (MEL). Blood samples were collected at 0.5-h intervals from h -2 to 4, 1.0-h intervals from h 4 to 8, and 12-h intervals from h 12 to 72. Serum was analyzed for cortisol and haptoglobin (Hp) concentrations using ELISA. Whole blood was analyzed for complete blood counts at -2, 0, 2, 4, 6, 8, 12, 24, 36, 48, 60, and 72 h, and RT was recorded in 5-min intervals. Postcastration RT was greatest for MEL (39.04), intermediate for CAS (38.99), and least for CON (38.93°C; ≤ 0.01). Serum cortisol was increased ( castration reduced the acute inflammatory response in castrates, as evidenced by a reduction in Hp and certain leukocyte concentrations; it also caused a delayed increase in RT. Further research is needed to determine if this reduced acute inflammatory response would equate to improved health and/or performance after castration.

    The authors have developed an improved version of the up-and-down procedure (UDP) as one of the replacements for the traditional acute oral toxicity test formerly used by the Organisation for Economic Co-operation and Development member nations to characterize industrial chemicals, pesticides, and their mixtures. This method improves the performance of acute testing for applications that use the median lethal dose (classic LD50) test while achieving significant reductions in animal use. It uses sequential dosing, together with sophisticated computer-assisted computational methods during the execution and calculation phases of the test. Staircase design, a form of sequential test design, can be applied to acute toxicity testing with its binary experimental endpoints (yes/no outcomes). The improved UDP provides a point estimate of the LD50 and approximate confidence intervals in addition to observed toxic signs for the substance tested. It does not provide information about the dose-response curve. Computer simulation was used to test performance of the UDP without the need for additional laboratory validation.

    Full Text Available Abstract Background Cannabis is the most commonly used illegal drug and its therapeutic aspects have a growing interest. Short-term psychotic reactions have been described but not clearly with synthetic oral THC, especially in occasional users. Case presentations We report two cases of healthy subjects who were occasional but regular cannabis users without psychiatric history who developed transient psychotic symptoms (depersonalization, paranoid feelings and derealisation following oral administration of cannabis. In contrast to most other case reports where circumstances and blood concentrations are unknown, the two cases reported here happened under experimental conditions with all subjects negative for cannabis, opiates, amphetamines, cocaine, benzodiazepines and alcohol, and therefore the ingested dose, the time-events of effects on behavior and performance as well as the cannabinoid blood levels were documented. Conclusion While the oral route of administration achieves only limited blood concentrations, significant psychotic reactions may occur.

    Children with acute lymphoblastic leukemia (ALL) are at increased risk of vitamin D deficiency, which might make them more susceptible to developing adverse events. Previous studies showed that low vitamin D levels were associated with an increased inflammatory mucosal state and impaired mucosal tissue barriers. We examined the prevalence of vitamin D deficiency and studied the association between vitamin D levels and methotrexate (MTX)-induced oral mucositis in pediatric ALL. We assessed 25-hydroxyvitamin D (25(OH)D 3 ) and 24,25-dihydroxyvitamin D (24,25(OH) 2 D 3 ) levels in 99 children with ALL before the start of 4 × 5 g/m 2 high-dose methotrexate (HD-MTX) (T0) and in 81/99 children after discontinuation of HD-MTX (T1). Two cutoff values for vitamin D deficiency exist: 25(OH)D 3 levels D deficiency occurred in respectively 8% ( 4 years of age as compared to children between 1 and 4 years of age. A decrease in 25(OH)D 3 levels during HD-MTX therapy was associated with developing severe oral mucositis (OR 1.6; 95% CI [1.1-2.4]). 25(OH)D 3 and 24,25(OH) 2 D 3 levels at T0 and the change in 24,25(OH) 2 D 3 levels during therapy were not associated with the development of severe oral mucositis. This study showed that vitamin D deficiency occurs frequently in pediatric ALL patients above the age of 4 years. A decrease in 25(OH)D 3 levels during MTX therapy was observed in children with ALL that developed severe oral mucositis.

    Full Text Available Oral rehydration salt (ORS treatment in young children with acute diarrhoea (AD has contributed to decrease mortality associated with dehydration although effective strategies to reduce morbidity associated with this disease are required. The aim of this study was to evaluate the diarrhoea duration when using combined colloidal bismuth hydroxide gel (CBHG and oral rehydration salt treatment compared with ORS therapy in children with AD. We designed a double-blind, randomised prospective study with treatment and control groups. Patients aged one to 12 years, with no prior pathology and with AD of less than 48 h were included. The Chi-squared and Mann-Whitney tests were used, as well as the Cox proportional hazards model and the Kaplan-Meier estimator. Patients were randomised into an ORS and CBHG treatment group and a control group for ORS plus placebo. (Average age: 3.2 years. The result of the post-treatment evaluation with respect to the average duration of AD was 25.5 h for the treated group vs. 41.5 h for the control group (p = 0.015. The average number of stools was 4.8 in the treated group and 8.2 in the control group (p = 0.032. We conclude that the use of CBHG plus ORS significantly reduced the duration of AD, the number of stools and the percentage of children with persistent AD after 24 h of treatment compared to the control group. AD remitted almost twice as fast in patients treated with CBHG and ORS compared to those who received ORS plus placebo.

    Background Antibiotic resistance is rising in important bacterial pathogens. Phage therapy (PT), the use of bacterial viruses infecting the pathogen in a species-specific way, is a potential alternative. Method T4-like coliphages or a commercial Russian coliphage product or placebo was orally given over 4 days to Bangladeshi children hospitalized with acute bacterial diarrhea. Safety of oral phage was assessed clinically and by functional tests; coliphage and Escherichia coli titers and enteropathogens were determined in stool and quantitative diarrhea parameters (stool output, stool frequency) were measured. Stool microbiota was studied by 16S rRNA gene sequencing; the genomes of four fecal Streptococcus isolates were sequenced. Findings No adverse events attributable to oral phage application were observed (primary safety outcome). Fecal coliphage was increased in treated over control children, but the titers did not show substantial intestinal phage replication (secondary microbiology outcome). 60% of the children suffered from a microbiologically proven E. coli diarrhea; the most frequent diagnosis was ETEC infections. Bacterial co-pathogens were also detected. Half of the patients contained phage-susceptible E. coli colonies in the stool. E. coli represented less than 5% of fecal bacteria. Stool ETEC titers showed only a short-lived peak and were otherwise close to the replication threshold determined for T4 phage in vitro. An interim analysis after the enrollment of 120 patients showed no amelioration in quantitative diarrhea parameter by PT over standard care (tertiary clinical outcome). Stool microbiota was characterized by an overgrowth with Streptococcus belonging to the Streptococcus gallolyticus and Streptococcus salivarius species groups, their abundance correlated with quantitative diarrhea outcome, but genome sequencing did not identify virulence genes. Interpretation Oral coliphages showed a safe gut transit in children, but failed to achieve

    One hundred twenty-eight nonmalnourished male patients between 3 and 36 months of age were randomly assigned to receive one of four lactose-free dietary treatments to determine the effect of dietary therapy on the severity and nutritional outcome of diarrheal illness. Group 1 received a formula diet composed of casein, sucrose, dextrin with maltose (Dextri-Maltose), and vegetable oil to provide 110 kcal/kg body weight/d (CSO-110). Group 2 received CSO to provide 55 kcal/kg/d (CSO-55) for 2 days and then CSO-110. Group 3 received only oral glucose-electrolyte solution (GES) for 2 days, CSO-55 for the next 2 days, and then CSO-110. Group 4 received the same diets as Group 3 except that only intravenous GES was used for the first 2 days. The GES maintenance solutions provided 24 to 30 kcal/kg/d. Therapeutic success rates were similar among dietary groups, ranging from 90% to 97%. Fecal excretion was initially lower in group 4 (P less than 0.05) but was similar initially among groups treated orally and among all four groups beginning on day 3. Net apparent absorption of nitrogen, fat, carbohydrate, and total energy; retention of nitrogen; and increments in body weight, arm circumference, and skin-fold thickness were positively related to the amounts of dietary energy consumed. Thus continued oral feeding with the CSO diets during the early phase of therapy yielded improved nutritional results.

    Several oral nonsteroidal anti-inflammatory drugs (NSAIDs) are effective to treat migraine attacks. Lysine clonixinate (LC) is a NSAID derived from nicotinic acid that has proven to be effective in various pain syndromes such as renal colic and muscular pain. The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of oral LC compared to placebo in the acute treatment of migraine. Sixty four patients with the diagnosis of migraine, according to the IHS criteria, were studied prospectively. Patients received LC or placebo once the headache reached moderate or severe intensity for 6 consecutive attacks. With regard to the moderate attacks, LC was superior than placebo after 1, 2 and 4 hours. The consumption of other rescue medications after 4 hours was significantly higher in the placebo group. With regard to the severe attacks, there was no difference between the active drug group and the placebo group concerning headache intensity and consumption of other rescue medications. We conclude that the NSAID lysine clonixinate is effective in treating moderately severe migraine attacks. It is not superior than placebo in treating severe migraine attacks.

    Acute generalized exanthematous pustulosis (AGEP) is a clinical reaction pattern characterized by the rapid appearance of widespread sterile, nonfollicular pustules arising within edematous erythematous skin. This aseptic pustular eruption is commonly accompanied by leukocytosis and fever and usually follows recent administration of oral or parenteral drugs. We report two cases of terbinafine-induced AGEP in male patients. Both patients developed a generalized erythroderma with scaling and pruritic pustules 7 and 14 days following initiation of oral terbinafine. With immediate discontinuation of terbinafine and various treatment protocols, both patients demonstrated recovery followed by skin desquamation during the subsequent weeks. Terbinafine is the most frequently used systemic antimycotic and antifungal medication, reflecting its superior efficacy for dermatophyte infections. Despite the appealing drug profile, an awareness of terbinafine-induced AGEP is important given the 5 percent mortality associated with AGEP. Additionally, distinguishing the characteristics of AGEP from those associated with toxic epidermal necrolysis, Stevens-Johnson syndrome, and generalized pustular psoriasis allows for prompt dermatologic evaluation, accurate diagnosis, and appropriate treatment.

    The safety of enzyme-treated asparagus extract (ETAS) developed as a novel anti-stress functional material was assessed in acute and subchronic studies and genotoxicity assays. In the acute oral dose toxicity study, all rats survived during the test period and ETAS did not influence clinical appearance, body weight gain and necropsy findings at a dosage of 2000mg/kg body weight. Thus, the 50% lethal dose (LD50) of ETAS was determined to be greater than 2000mg/kg. The 90-day subchronic study (500, 1000 and 2000mg/kg body weight, delivered by gavage) in rats reported no significant adverse effects in food consumption, body weight, mortality, urinalysis, hematology, biochemistry, necropsy, organ weight and histopathology. In the micronucleus test of mice, the incidence of micronuclei in ETAS-administered groups (500, 1000 and 2000mg/kg/day, injected twice) was equivalent to that of the negative control group, while the positive control group receiving mitomycin C showed a high incidence. The potential of ETAS to induce gene mutation was tested using four Salmonella typhimurium strains and Escherichia coli WP2uvrA. The test sample was not mutagenic to the test strains. These results support the safety of ETAS as food and dietary supplement. Copyright © 2014 Elsevier Inc. All rights reserved.

    Ibuprofen and paracetamol have long been used as analgesics in a range of acute, intermittent and chronic pain conditions. Paracetamol is often the first line analgesic recommended, without consensus about which is the better analgesic. An overview review of systematic reviews and meta-analyses directly compares ibuprofen and paracetamol at standard doses in particular painful conditions, or uses indirect comparisons against placebo. Electronic searches for systematic reviews were sought published since 1995 using outcomes approximating to ≥50% pain intensity reduction. Painful conditions were acute post-operative pain, dysmenorrhoea, tension-type headache (TTH), migraine, osteoarthritis and rheumatoid arthritis, back pain, cancer and paediatric pain. There was no systematic assessment of harm. Sixteen systematic reviews and four individual patient data meta-analyses were included. Ibuprofen was consistently superior to paracetamol at conventional doses in a range of painful conditions. Two direct comparisons favoured ibuprofen (acute pain, osteoarthritis). Three of four indirect comparisons favoured ibuprofen (acute pain, migraine, osteoarthritis); one showed no difference (TTH), although there were methodological problems. In five pain conditions (dysmenorrhoea, paediatric pain, cancer pain, back pain and rheumatoid arthritis), there were limited data on paracetamol and ibuprofen. At standard doses in different painful conditions, ibuprofen was usually superior producing more patients with the degree of pain relief that patients feel worthwhile. Neither of the drugs will be effective for everyone, and both are needed. This overview questions the practice of routinely using paracetamol as a first line analgesic because there is no good evidence for efficacy of paracetamol in many pain conditions. © 2014 The Authors.

    Full Text Available Background: To assess the therapeutic effects of oral zinc supplementation on acute watery diarrhea of children with moderate dehydration.Methods: All 9-month to 5-year-old children who were admitted with acute watery diarrhea and moderate dehydration to the Children Ward of Motahari Hospital, Urmia, Iran in 2008 were recruited. After the application of the inclusion and exclusion criteria, the patients were randomly allocated to two groups: one group to receive zinc plus oral rehydration solution (ORS and the other one to receive ORS plus placebo. All the patients were rehydrated using ORS and then receiving ORS for ongoing loss (10 ml/kg after every defecation. Additionally, the patients in the intervention group received zinc syrup (1 mg/kg/day divided into two doses. A detailed questionnaire was filled daily for each patient by trained pediatrics residents; it contained required demographic characteristics, nutrition and hydration status, and disease progression. The primary outcome (frequency and consistency of diarrhea and the secondary outcomes (duration of hospitalization and change in patients’ weight were compared between the two groups.Results: The mean diarrhea frequency (4.5±2.3 vs. 5.3±2.1; P=0.004 was lower in the group receiving zinc +ORS; however, the average weight was relatively similar between the two groups (10.5±3.1 vs. 10.1±2.3; P=0.14. The qualitative assessment of stool consistency also confirmed earlier improvement in the treatment group in the first three days of hospitalization (P <0.05. The mean duration of hospitalization was significantly lower in the patients receiving zinc supplements (2.5±0.7 vs. 3.3±0.8 days; P=0.001. Conclusion: Our results imply the beneficial effects of therapeutic zinc supplementation on disease duration and severity in patients with acute diarrhea and moderate dehydration in Iran.

    Objective The study compared the sensitivity, specificity, confidence and interpretation time of readers of differing experience in diagnosing acute appendicitis with contrast-enhanced CT using neutral vs positive oral contrast agents. Methods Contrast-enhanced CT for right lower quadrant or right flank pain was performed in 200 patients with neutral and 200 with positive oral contrast including 199 with proven acute appendicitis and 201 with other diagnoses. Test set disease prevalence was 50%. Two experienced gastrointestinal radiologists, one fellow and two first-year residents blindly assessed all studies for appendicitis (2000 readings) and assigned confidence scores (1=poor to 4=excellent). Receiver operating characteristic (ROC) curves were generated. Total interpretation time was recorded. Each reader's interpretation with the two agents was compared using standard statistical methods. Results Average reader sensitivity was found to be 96% (range 91–99%) with positive and 95% (89–98%) with neutral oral contrast; specificity was 96% (92–98%) and 94% (90–97%). For each reader, no statistically significant difference was found between the two agents (sensitivities p-values >0.6; specificities p-values>0.08), in the area under the ROC curve (range 0.95–0.99) or in average interpretation times. In cases without appendicitis, positive oral contrast demonstrated improved appendix identification (average 90% vs 78%) and higher confidence scores for three readers. Average interpretation times showed no statistically significant differences between the agents. Conclusion Neutral vs positive oral contrast does not affect the accuracy of contrast-enhanced CT for diagnosing acute appendicitis. Although positive oral contrast might help to identify normal appendices, we continue to use neutral oral contrast given its other potential benefits. PMID:20959365

    Full Text Available Objective: To evaluate the acute and subacute toxicity of 50% ethanolic extract of Tephrosia purpurea (T. purpurea in rodents. Methods: The acute toxicity test was conducted in Swiss albino mice. The extract of T. purpurea was administrated in single doses of 50, 300 and 2000 mg/ kg and observed for behavioral changes and mortality, if any. In subacute toxicity study, Wistar rats of either sex were administered two doses of T. purpurea i.e., 200 and 400 mg/kg (One-tenth and one-fifth of the maximum tolerated dose, p.o. for 4 weeks. During 28 days of treatment, rats were observed weekly for any change in their body weight, food and water intake. At the end of 28 days, rats were sacrificed for hematological, biochemical and histopathology study. Results: In the acute toxicity study, T. purpurea was found to be well tolerated upto 2 000 mg/kg, produced neither mortality nor changes in behavior in mice. In subacute toxicity study, T. purpurea at dose level of 200 and 400 mg/kg did not produce any significant difference in their body weight, food and water intake when compared to vehicle treated rats. It also showed no significant alteration in hematological and biochemical parameters in experimental groups of rats apart from a decrease in aspartate transaminase, alanine transaminase and alkaline phosphate content at the dose of 400 mg/kg. Histopathological study revealed normal architecture of kidney and liver of T. purpurea treated rats. Conclusions: These results demonstrated that there is a wide margin of safety for the therapeutic use of T. purpurea and further corroborated the traditional use of this extract as an anti hepatocarcinogenic agent

    Although there is increased acceptance and utilization of medicinal plants worldwide, many are used indiscriminately without recourse to any safety test. Thus, the need for toxicity tests to determine the safe dose for oral consumption. LD50 and phytochemistry of four medicinal plants of West Africa were investigated. Thirty male and non pregnant female Swiss albino mice weighing 20grams each were used for this study. They were divided into the Control (C), Oldenlandia corymbosa L. aqueous leaf-extract treated (OCG), Parquetina nigrescens aqueous leaf extract treated (PNG), Hybanthus enneaspermus aqueous leaf extract treated (HEG), Ficus carica leaf extract treated (FCG) and Sesamum indicum aqueous seeds extract treated group (SIG). Each group except the control was further divided into four sub-groups of six mice each, and were administered orally, graded doses (SI; 1, 2, 4 and 8, PN; 2.5, 5, 10 and 20, OC; 5, 10, 20 and 40, FC; 1, 2, 4 and 8, HE; 4, 8, 16, 32) of the aqueous extract of each plant (g/kg body weight) after 12 hours fasting. The dry aqueous leaf extracts of HE, OC, PN, FC all have dark brown colour and pH ranging from 6.1 to 7.2 while the seed extract of SI has a light brown color with pH of 7.0. Flavonoids, cardiac glycosides, anthocyanosides, saponin, and reducing sugar were present in all extracts, while cyanogenic glycoside was present only in HE. LD50 determination results obtained using Thompson and Finney methods were as follows; OC; 14.14 +/- 0.27 and 10.56 +/- 0.20, PN; 12.60 +/- 0.10 and 13.10 +/- 0.10, HE; 8.14 +/- 0.30 and 8.24 +/- 0.35, FC; 3.36 +/- 0.26 and 4.00 +/- 0.04, SI; 4.00 +/- 0.10 and 3.10 +/- 0.22 respectively (LD50 values are in g/kg body weight. The results of this study have provided an oral LD50 from where a safe dose can be chosen for further research into the merits of the consumption of these medicinal plants.

    Tartrazine has been frequently linked to several diseases. However, a cause-and-effect role for tartrazine in these illnesses, especially in urticaria, has not always been established. The aim of this study is to determine the incidence of intolerance to tartrazine among subjects who experienced an acute episode of urticaria/angioedema following the ingestion of a meal or a product containing this substance. This was a retrospective study based on analysis of data of patients reported to have experienced episodes of urticaria and/or angioedema after ingesting meals or products containing tartrazine. At the first visit to the outpatients clinic, a careful anamnesis had been taken. Patients had then been submitted to the following diagnostic tests: IgE tests to common inhalant allergens and food allergens and a double-blind placebo-controlled challenge with tartrazine. A total of 102 subjects were enrolled in the study: 19 (18.6%) showed at least one relevant positive reaction to an IgE test for food allergy. Only one subject (1%) had reactions after ingestion of 5 mg of tartrazine, given on day 5. She did not have adverse reactions to placebo. This study shows that the percentage of acute urticaria and/or angioedema induced by tartrazine is very low (1%). In view of our results, we suggest that all physicians with patients who have suffered adverse reactions that could be attributed to tartrazine should also carefully evaluate other possible causes.

    Background: Radiotherapy in cancer of the head and neck induces cutaneous and mucosal reactions. These must be carefully assessed and documented to control the accuracy of individual treatment, the overall toxicity of particular treatment schedules, the efficacy of prophylaxis and treatment and to determine the adequate therapy of treatment sequelae depending on the severity of the reactions. The accurate classification of lesions according to internationally accepted schedules (WHO/RTOG/CTC) is indispensable for the comparison of radiotherapy treatment results and efficacy of supportive care. Methods: While the treatment of cancer depends on tumor stage and medical circumstances of the patient and is more or less standardized, prophylaxis and treatment of side-effects is highly variable. Discussing an optimized prophylaxis and therapy of oral mucositis, the problem of accurate classification and documentation emerged. The verbal description of mucosal lesions is open to many subjective interpretations. Photographic documentation seems a suitable method to optimize the grading of toxicity. Results: A photographic survey of typical lesions for each grade of toxicity is a tool to reach several aims in one step. Toxicity of an individual patient may be compared with representative photographic examples in daily routine to decide quickly on the grade of toxicity. Subjective differences due to intra- and interpersonal variability of the evaluating radiooncologist will be reduced. The efficacy of trof treatment can be proven by accurate documentation. Randomized clinical studies concerning prophylaxis and treatmen mucositis will provide more reliable results if evaluation of toxicity grading is standardized by photographs. Conclusions: Photographic documentation of lesions of the oral mucosa might be the best means to reduce interindividual subjectivity in grading. It is a valuable appendix to standard classification systems and only concerns the visible signs of mucosal

    Nearly 60% of patients who are intubated in intensive care units (ICUs) experience dysphagia after extubation, and approximately 50% of them aspirate. Little is known about dysphagia recovery time after patients are discharged from the hospital. To determine factors associated with recovery from dysphagia symptoms after hospital discharge for acute respiratory distress syndrome (ARDS) survivors who received oral intubation with mechanical ventilation. This is a prospective, 5-year longitudinal cohort study involving 13 ICUs at four teaching hospitals in Baltimore, Maryland. The Sydney Swallowing Questionnaire (SSQ), a 17-item visual analog scale (range, 0-1,700), was used to quantify patient-perceived dysphagia symptoms at hospital discharge, and at 3, 6, 12, 24, 36, 48, and 60 months after ARDS. An SSQ score greater than or equal to 200 was used to indicate clinically important dysphagia symptoms at the time of hospital discharge. Recovery was defined as an SSQ score less than 200, with a decrease from hospital discharge greater than or equal to 119, the reliable change index for SSQ score. Fine and Gray proportional subdistribution hazards regression analysis was used to evaluate patient and ICU variables associated with time to recovery accounting for the competing risk of death. Thirty-seven (32%) of 115 patients had an SSQ score greater than or equal to 200 at hospital discharge; 3 died before recovery. All 34 remaining survivors recovered from dysphagia symptoms by 5-year follow-up, 7 (23%) after 6 months. ICU length of stay was independently associated with time to recovery, with a hazard ratio (95% confidence interval) of 0.96 (0.93-1.00) per day. One-third of orally intubated ARDS survivors have dysphagia symptoms that persist beyond hospital discharge. Patients with a longer ICU length of stay have slower recovery from dysphagia symptoms and should be carefully considered for swallowing assessment to help prevent complications related to dysphagia.

This study was aimed at evaluating acute toxicity and anti-inflammatory activity of Lampaya medicinalis Phil. (Verbenaceae) widely used in the folk medicine of Northern Chile against rheumatism, arthritis and body joints pain. Oral administration of hydroalcoholic extract (HAE) at the highest dose of 3000 mg/ Kg body weight resulted in no mortalities or evidence of significant behavioral changes. Histological examination revealed normal architecture and no significant adverse effects were observed on the liver, kidney, heart, lung or ovaries and testicles. The results suggest that the oral administration of hydroalcoholic extract (HAE) from Lampaya medicinalis did not produce any toxic effect in rats. Hydroalcoholic extract (HAE) significantly inhibited the carrageenan-induced rat paw edema in dose - response relationship, at test doses of 37.5, 75, 150 and 300 mg/Kg body weight. Maximum inhibition (61.98 ± 2.69%) was noted at 300 mg/Kg after 2 h of drug treatment carrageenan induced paw edema, whereas indomethacin produced 47.90 ± 1.16% of inhibition. The inhibitory values of edema at 3 h postcarrageenan were 31.04 ± 0.75%, 40.51 ± 2.36%, 48.97 ± 1.14% and 56.87 ± 0.41% for 37.5, 75, 150, and 300 mg/kg of extract respectively. Indomethacin (10 mg/Kg) gave a percentage inhibition of 49.44 ± 1.44. HAE (300 and 150 mg/kg) induced an anti-inflammatory effect greater than (or comparable) with the effect of indomethacin from 2nd to 4th hours of the experiment. Our results reveal for first time that compounds contained in the hydroalcoholic extract of Lampaya medicinalis Phil exert anti-inflammatory effect and the oral administration is safe and non toxic up to dose level 3000 mg/kg body weight. The anti-inflammatory activity may be associated with the presence of flavonoids. These

    Background: Radiotherapy in cancer of the head and neck induces cutaneous and mucosal reactions. These must be carefully assessed and documentated to control the accuracy of individual treatment, the overall toxicity of particular treatment schedules, the efficacy of prophylaxis and treatment and to determine the adequate therapy of treatment sequelae depending on the severity of the reactions. The accurate classification of lesions according to internationally accepted schedules (WHO/RTOG/CTC) is indispensable for the comparison of radiotherapy treatment results and efficacy of supportive care. Methods: While the treatment of cancer depends on tumor stage and medical circumstances of the patient and is more or less standardized, prophylaxis and treatment of side-effects is highly variable. Discussing an optimized prophylaxis and therapy of oral mucositis, the problem of accurate classification and documentation emerged. The verbal description of mucosal lesions is open to many subjective interpretations. Photographic documentation seems a suitable method to optimize the grading of toxicity. Results: A photographic survey of typical lesions for each grade of toxicity is a tool to reach several aims in one step. Toxicity of an individual patient may be compared with representative photographic examples in daily routine to decide quickly on the grade of toxicity. Subjective differences due to intra- and interpersonal variability of the evaluating radiooncologist will be reduced. The efficacy of trof treatment can be proven by accurate documentation. Randomized clinical studies concerning prophylaxis and treatmen mucositis will provide more reliable results if evaluation of toxicity grading is standardized by photographs. Conclusions: Photographic documentation of lesions of the oral mucosa might be the best means to reduce interindividual subjectivity in grading. It is a valuable appendix to standard classification systems and only concerns the visible signs of

    Full Text Available We present the case of a 28-year-old woman who was admitted to our cardiology unit for acute coronary syndrome. Her history was notable for cardiovascular disease familiarity, active smoking, and oral contraceptive use. On further analysis, she was noted to have thrombophilic polymorphisms involving the plasminogen activator inhibitor (PAI, angiotensin-converting enzyme (ACE, and methylenetetrahydrofolate reductase (MTHFR genes. We discuss the implications that these cofactors may have had in the genesis of the disease.

    Non-combustible potential reduced exposure products (PREPs; eg, Star Scientific's Ariva; a variety of other smokeless tobacco products) are marketed to reduce the harm associated with smoking. This marketing occurs despite an absence of objective data concerning the toxicant exposure and effects of these PREPs. Methods used to examine combustible PREPs were adapted to assess the acute effects of non-combustible PREPs for smokers. 28 overnight abstinent cigarette smokers (17 men, 14 non-white) each completed seven, Latin-squared ordered, approximately 2.5 h laboratory sessions that differed by product administered: Ariva, Marlboro Snus (Philip Morris, USA), Camel Snus (RJ Reynolds, Winston-Salem, North Carolina, USA), Commit nicotine lozenge (GlaxoSmithKline; 2 mg), own brand cigarettes, Quest cigarettes (Vector Tobacco; delivers very low levels of nicotine) and sham smoking (ie, puffing on an unlit cigarette). In each session, the product was administered twice (separated by 60 min), and plasma nicotine levels, expired air CO and subjective effects were assessed regularly. Non-combustible products delivered less nicotine than own brand cigarettes, did not expose smokers to CO and failed to suppress tobacco abstinence symptoms as effectively as combustible products. While decreased toxicant exposure is a potential indicator of harm reduction potential, a failure to suppress abstinence symptoms suggests that currently marketed non-combustible PREPs may not be a viable harm reduction strategy for US smokers. This study demonstrates how clinical laboratory methods can be used to evaluate the short-term effects of non-combustible PREPs for smokers.

    Full Text Available Abstract Background Vomiting in children with acute gastroenteritis (AG is not only a direct cause of fluid loss but it is also a major factor of failure of oral rehydration therapy (ORT. Physicians who provide care to paediatric patients in the emergency department (ED usually prescribe intravenous fluid therapy (IVT for mild or moderate dehydration when vomiting is the major symptom. Thus, effective symptomatic treatment of vomiting would lead to an important reduction in the use of IVT and, consequently, of the duration of hospital stay and of frequency of hospital admission. Available evidence on symptomatic treatment of vomiting shows the efficacy of the most recently registered molecule (ondansetron but a proper evaluation of antiemetics drugs largely used in clinical practice, such as domperidone, is lacking. Objectives To compare the efficacy of ondansetron and domperidone for the symptomatic treatment of vomiting in children with AG who have failed ORT. Methods/Design Multicentre, double-blind randomized controlled trial conducted in paediatric EDs. Children aged from 1 to 6 years who vomiting, with a presumptive clinical diagnosis of AG, and without severe dehydration will be included. After the failure of a initial ORS administration in ED, eligible children will be randomized to receive: 1 ondansetron syrup (0,15 mg/Kg of body weight; 2 domperidone syrup (0,5 mg/Kg of body weight; 3 placebo. The main study outcome will be the percentage of patients needing nasogastric or IVT after symptomatic oral treatment failure, defined as vomiting or fluid refusal after a second attempt of ORT. Data relative to study outcomes will be collected at 30 minute intervals for a minimum of 6 hours. A telephone follow up call will be made 48 hours after discharge. A total number of 540 children (i.e. 180 patients in each arm will be enrolled. Discussion The trial results would provide evidence on the efficacy of domperidone, which is largely used in

    Full Text Available Evidence supporting the impact of therapeutic zinc supplementation on the duration and severity of diarrhea among children under five is largely derived from studies conducted in South Asia. China experiences a substantial portion of the global burden of diarrhea, but the impact of zinc treatment among children under five has not been well documented by previously published systematic reviews on the topic. We therefore conducted a systematic literature review, which included an exhaustive search of the Chinese literature, in an effort to update previously published estimates of the effect of therapeutic zinc. We conducted systematic literature searches in various databases, including the China National Knowledge Infrastructure (CNKI, and abstracted relevant data from studies meeting our inclusion and exclusion criteria. We used STATA 12.0 to pool select outcomes and to generate estimates of percentage difference and relative risk comparing outcomes between zinc and control groups. We identified 89 Chinese and 15 non-Chinese studies for the review, including studies in 10 countries from all WHO geographic regions, and analyzed a total of 18,822 diarrhea cases (9469 zinc and 9353 control. None of the included Chinese studies had previously been included in published pooled effect estimates. Chinese and non-Chinese studies reported the effect of therapeutic zinc supplementation on decreased episode duration, stool output, stool frequency, hospitalization duration and proportion of episodes lasting beyond three and seven days. Pooling Chinese and non-Chinese studies yielded an overall 26% (95% CI: 20%−32% reduction in the estimated relative risk of diarrhea lasting beyond three days among zinc-treated children. Studies conducted in and outside China report reductions in morbidity as a result of oral therapeutic zinc supplementation for acute diarrhea among children under five years of age.

    We evaluated 50 consecutive patients who received thrombolytic therapy for acute myocardial infarction using thallium-201 single photon emission computed tomography in combination with oral dipyridamole to assess the frequency of residual myocardial ischemia. Thallium studies were performed early after myocardial infarction at a mean of 4.6 days. The time from the onset of chest pain to the administration of thrombolytic therapy was 2.6 hours (range 0.5 to 5.5). Q wave myocardial infarction was evident in 46 patients; four patients had a non-Q wave infarction (anterior infarction in 31 patients and inferior infarction in 19 patients). The serum mean peak creatinine kinase was 1503 IU/L (range 127 to 6500). Coronary angiography was performed in all patients at a mean of 3.1 days (range 2 to 10) and revealed the infarct-related vessel to be patent in 36 patients (72%). The ejection fraction was 48% (range 26% to 67%). After dipyridamole administration, 13 patients (26%) developed angina that was easily reversed with the administration of intravenous aminophylline. Systolic blood pressure decreased from 122 to 115 mm Hg (p less than 0.05) and the heart rate increased from 76 to 85 beats/min (p less than 0.05). None of the patients had significant hypotension, arrhythmias, or evidence of infarct extension. Perfusion abnormalities were present on the initial thallium images in 48 patients. Redistribution suggestive of ischemia was present in 36 patients (72%). Ischemia confined to the vascular distribution of the infarct vessel was evident in 22 patients. Seven patients had ischemia in the infarct zone as well as in a remote myocardial segment. Thus 29 patients (58%) had ischemia in the distribution of the infarct vessel. Ischemia in the infarct zone was evident in 19 of 36 patients with open infarct vessels and in 10 of 14 patients with occluded infarct vessels

    The International Headache Society (IHS) provides guidance on the conduct of trials for acute treatment of episodic tension-type headache (TTH), a common disorder with considerable disability. Electronic and other searches identified randomised, double-blind trials of oral drugs treating episodic TTH with moderate or severe pain at baseline, or that tested drugs at first pain onset. The aims were to review methods, quality, and outcomes reported (in particular the IHS-recommended primary efficacy parameter pain-free after 2 hours), and to assess efficacy by meta-analysis. We identified 58 reports: 55 from previous reviews and searches, 2 unpublished reports, and 1 clinical trial report with results. We included 40 reports of 55 randomised trials involving 12,143 patients. Reporting quality was generally good, with potential risk of bias from incomplete outcome reporting and small size; the 23 largest trials involved 82% of patients. Few trials reported IHS outcomes. The number needed to treat values for being pain-free at 2 hours compared with placebo were 8.7 (95% confidence interval [CI] 6.2 to 15) for paracetamol 1000 mg, 8.9 (95% CI 5.9 to 18) for ibuprofen 400mg, and 9.8 (95% CI 5.1 to 146) for ketoprofen 25mg. Lower (better) number needed to treat values were calculated for outcomes of mild or no pain at 2 hours, and patient global assessment. These were similar to values for these drugs in migraine. No other drugs had evaluable results for these patient-centred outcomes. There was no evidence that any one outcome was better than others. The evidence available for treatment efficacy is small in comparison to the size of the clinical problem. Copyright © 2014 International Association for the Study of Pain. Published by Elsevier B.V.

    A series of safety assessments were performed on hydrogenated resistant maltodextrin prepared by converting the reducing terminal glucose of resistant maltodextrin into sorbitol. The reverse mutation assay did not show mutagenicity. Acute and 90-day subchronic oral toxicity studies in rats showed no death was observed in any groups, including the group receiving the highest single dose of 10 g/kg body weight or the highest dose of 5 g/kg body weight per day for 90 days. Mucous or watery stools were observed in the hydrogenated resistant maltodextrin treatment group on the acute study, which were transient and were associated with the osmotic pressure caused by intake of the high concentrations. Subchronic study showed dose-dependent increases in the weights of cecum alone, cecal contents alone, and cecum with cecal contents as well as hypertrophy of the cecal mucosal epithelium, which are considered to be common physiological responses after intake of indigestible carbohydrates. These results indicated that the no observed adverse effect level (NOAEL) of hydrogenated resistant maltodextrin was 10 g/kg body weight or more on the acute oral toxicity study and 5.0 g/kg body weight/day or more on the 90-day subchronic repeated oral toxicity study in rats. Further study performed in healthy adult humans showed that the acute no-effect level of hydrogenated resistant maltodextrin for diarrhea was 0.8 g/kg body weight for men and more than 1.0 g/kg body weight for women. The results of the current safety assessment studies suggest that hydrogenated resistant maltodextrin is safe for human consumption.

    Full Text Available Abstract Background To treat acute schizophrenia, a long-acting injectable antipsychotic needs a rapid onset of action and therapeutic profile similar to that of oral agents. The present post-hoc analyses compared results from a randomized, double-blind, placebo-controlled trial of olanzapine long-acting injection (LAI for acute schizophrenia with those observed in similarly designed trials of oral olanzapine. Methods Six-week results from the olanzapine LAI study (N = 404 were compared with those of 3 oral studies (study 1: olanzapine vs. haloperidol vs. placebo [N = 335]; study 2: olanzapine vs. haloperidol vs. low-dose olanzapine [N = 431]; study 3: olanzapine vs. placebo vs. low-dose olanzapine [N = 152]. All patients had baseline Brief Psychiatric Rating Scale (BPRS scores ≥24 (0–6 scale. Six-week effect sizes were calculated. Efficacy onset, pharmacokinetics, discontinuations, weight gain, and extrapyramidal symptoms were also assessed. Results At 6 weeks, mean BPRS scores decreased by 14 to 15 points for olanzapine LAI (405 mg/4 weeks, 210 or 300 mg/2 weeks, by 8 to 16 for oral olanzapine (10 ± 2.5 or 15 ± 2.5 mg/day, and by 12 to 13 for haloperidol (15 ± 5 mg/day. For those same dose groups, effect sizes vs. placebo for the BPRS were 0.7 to 0.8 for olanzapine LAI, 0.5 to 0.7 for oral olanzapine, and 0.6 for haloperidol. The first statistically significant separation from placebo on the BPRS occurred at 3 days for the olanzapine LAI groups and at 1 week for oral olanzapine and haloperidol (15 ± 5 mg/day in oral study 1 although as late as week 6 for the 10-mg/day olanzapine dose in oral study 3. Olanzapine concentrations were similar across studies. Weight gain ≥7% of baseline occurred in up to 35% of olanzapine LAI and oral patients versus up to 12% of haloperidol and placebo patients. Extrapyramidal symptoms were lowest in the olanzapine LAI groups and significantly greater

  5. Orally administered indomethacin acutely reduces cellular prion protein in the small intestine and modestly increases survival of mice exposed to infectious prions.

    The oral uptake of infectious prions represents a common way to acquire a prion disease; thus, host factors, such as gut inflammation and intestinal "leakiness", have the potential to influence infectivity. For example, the ingestion of nonsteroidal anti-inflammatory drugs (NSAIDs) is known to induce intestinal inflammation and increase intestinal permeability. Previously, we reported that normal cellular prion protein (PrP(C)) expression was increased in experimental colitis, and since the level of PrP(C) expressed is a determinant of prion disease propagation, we hypothesized that NSAID administration prior to the oral inoculation of mice with infectious prions would increase intestinal PrP(C) expression and accelerate the onset of neurological disease. In the long-term experiments, one group of mice was gavaged with indomethacin, followed by a second gavage with brain homogenate containing mouse-adapted scrapie (ME7). Control mice received ME7 brain homogenate alone. Brain and splenic tissues were harvested at several time points for immunoblotting, including at the onset of clinical signs of disease. In a second series of experiments, mice were gavaged with indomethacin to assess the acute effects of this treatment on intestinal PrP(C) expression. Acutely, NSAID treatment reduced intestinal PrP(C) expression, and chronically, there was a modest delay in the onset of neurological disease. In contrast to our hypothesis, brief exposure to an NSAID decreased intestinal PrP(C) expression and led to a modest survival advantage following oral ingestion of infectious prions.

    The anti-psoriatic efficacy of orally administered methotrexate loaded chitin nanogel (MCNG) was evaluated (two doses- 2.715 mg/kg and 5.143 mg/kg) and compared against orally administered methotrexate tablet MTX (5.143 mg/kg). MCNG at both dose levels of 2.715 mg/kg and 5.143 mg/kg exhibited significant anti-psoriatic activity which is very much comparable with MTX, caused normalization of histological features and inflammatory score associated with induced psoriasis. Biodistribution studies revealed the presence of drug in serum and in vital organs at all the three cases with highest amount in MCNG at 5.143 mg/kg dose, followed by MTX tablet and are lowest in MCNG at 2.715 mg/kg dose. MCNG at the highest dose of 5.143 mg/kg caused liver, lung and kidney toxicities on sub acute toxicity studies and MTX tablet was found to be toxic on liver and lung on sub chronic toxicity studies. MCNG 2.715 mg/kg was found to be safe on both sub acute and sub chronic administrations, suggesting that it can provide sufficient serum and tissue level of methotrexate necessary to clear psoriatic lesions, without inducing systemic toxicity and expected to be a better alternative for orally administered conventional methotrexate tablet for patients who need systemic medications for psoriasis.

    The objective of this study was to evaluate the preventive effects of oral administration of lansoprazole on acute exacerbation of chronic obstructive pulmonary disease (COPD). Patients with COPD in groups C and D in the stable phase were stratified into a group with neither gastroesophageal reflux nor lansoprazole therapy (group A) and a group subjected to oral lansoprazole therapy (group B1 ) and a group not subjected to oral lansoprazole therapy (group B2 ). The frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire, COPD assessment test (CAT) questionnaire, pulmonary function test and the 6-minute walk test were applied; in addition, arterial blood gas, white blood cell (WBC), hs-CRP, liver function and the levels of IL-1β, IL-6, IL-8, TNF-α and GM-CSF in sputum were monitored during follow-up. In the 12-month follow-up period, the frequency of exacerbation in group B2 was statistically higher than that in groups A and B1 (P lansoprazole therapy decreased the frequency of acute exacerbation of COPD by alleviating gastroesophageal reflux and lowering the levels of IL-1β, IL-6, IL-8, TNF-α and GM-CSF in the sputum. © 2016 The Authors.

    The purpose of this study was to evaluate the potential of oral combined cannabis constituents to reduce nausea. The objective of this study was to determine the effect of combining subthreshold oral doses of Δ(9)-tetrahydrocannabinol (THC) and cannabidiolic acid (CBDA) on acute and anticipatory nausea in rat models of conditioned gaping. The potential of intragastric (i.g.) administration of THC, CBDA, or combined doses, to interfere with acute nausea-induced conditioned gaping (acute nausea) or the expression of contextually elicited conditioned gaping (anticipatory nausea), was evaluated. For acute nausea, i.g. administration of subthreshold doses of THC (0.5 and 1 mg/kg) or CBDA (0.5 and 1 μg/kg) significantly suppressed acute nausea-induced gaping, whereas higher individual doses of both THC and CBDA were maximally effective. Combined i.g. administration of higher doses of THC and CBDA (2.5 mg/kg THC-2.5 μg/kg CBDA; 10 mg/kg THC-10 μg/kg CBDA; 20 mg/kg THC-20 μg/kg CBDA) also enhanced positive hedonic reactions elicited by saccharin solution during conditioning. For anticipatory nausea, combined subthreshold i.g. doses of THC (0.1 mg/kg) and CBDA (0.1 μg/kg) suppressed contextually elicited conditioned gaping. When administered i.g., THC was effective on its own at doses ranging from 1 to 10 mg/kg, but CBDA was only effective at 10 μg/kg. THC alone was equally effective by intraperitoneal (i.p.) and i.g. administration, whereas CBDA alone was more effective by i.p. administration (Rock et al. in Psychopharmacol (Berl) 232:4445-4454, 2015) than by i.g. administration. Oral administration of subthreshold doses of THC and CBDA may be an effective new treatment for acute nausea and anticipatory nausea and appetite enhancement in chemotherapy patients.

    D-tagatose, a stereoisomer of D-fructose, is a naturally occurring ketohexose proposed for use as a low-calorie bulk sweetener. Ingested D-tagatose appears to be poorly absorbed. The absorbed portion is metabolized in the liver by a pathway similar to that of D-fructose. The main purpose of this study was to determine if acute or repeated oral doses of D-tagatose would cause elevations in plasma uric acid (as is seen with fructose) in normal humans and Type 2 diabetics. In addition, effects of subchronic D-tagatose ingestion on fasting plasma phosphorus, magnesium, lipids, and glucose homeostasis were studied. Eight normal subjects and eight subjects with Type 2 diabetes participated in this two-phase study. Each group was comprised of four males and four females. In the first phase, all subjects were given separate 75 g 3-h oral glucose and D-tagatose tolerance tests. Uric acid, phosphorus, and magnesium were determined in blood samples collected from each subject at 0, 30, 60, 120, and 180 min after dose. In the 8-week phase of the study, the normals were randomly placed into two groups which received 75 g of either D-tagatose or sucrose (25 g with each meal) daily for 8 weeks. The diabetics were randomized into two groups which received either 75 g D-tagatose or no supplements of sugar daily for 8 weeks. Uric acid, phosphorus, magnesium, lipids, glycosylated hemoglobin, glucose, and insulin were determined in fasting blood plasma of all subjects at baseline (time zero) and biweekly over the 8 weeks. The 8-week test did not demonstrate an increase in fasting plasma uric acid in response to the daily intake of D-tagatose. However, a transient increase of plasma uric acid levels was observed after single doses of 75 g of D-tagatose in the tolerance test. Plasma uric acid levels were found to rise and peak at 60 min after such dosing. No clinical relevance was attributed to this treatment-related effect because excursions of plasma uric acid levels above the normal

    Experience with administration of synbiotics (prebiotics/probiotics) in patients with severe acute pancreatitis (SAP) has demonstrated immunomodulatory capacity. The aim of this trial was evaluation of the feasibility and perspective of early clinical application of oral synbiotic/prebiotic supplements in patients with SAP. 90 SAP patients were enrolled during the period from 2005-2008. Patients were stratified according to the feeding mode. CONTROL (n = 32) group received standard whole protein feeding formula. SYNBIO (n = 30) and FIBRE groups (n = 28) received early (within first 24-48 hours) synbiotic or prebiotic supplements. Oral administration of synbiotics or prebiotics was commenced when patients were able to sip water. Daily provided average volume and calories of synbiotic/prebiotic blends were smaller compared to the CONTROL, p = 0.001. Oral administration of synbiotic/prebiotic supplements was associated with lower infection rate (pancreatic and peripancreatic necrosis) compared to the CONTROL, (p = 0.03; p = 0.001), lower rate of surgical interventions, p = 0.005, shorter ICU (p = 0.05) and hospital stay (p = 0.03). Synbiotic supplemented enteral stimulation of the gut resulted in reduced mortality rate compared to the CONTROL, p = 0.02. Early low volume oral synbiotic/prebiotic supplemented enteral stimulation of the gut seems to be a potentially valuable complement to the routine treatment protocol of SAP.

    Children and adolescents with acute lymphoblastic leukemia (A.L.L.) receive treatment that relies on daily self- or parent/caregiver-administered oral chemotherapy for approximately two years. Despite the fact that pediatric A.L.L. is uniformly fatal without adequate treatment, non-adherence to oral chemotherapy has been observed in up to one-third of patients. Little is known about the reasons for non-adherence in these patients. This study employed Straussian grounded theory methodology to develop and validate a model to explain the process of adherence to oral chemotherapy in children and adolescents with A.L.L. Thirty-eight semi-structured interviews (with 17 patients and 21 parents/caregivers) and four focused group discussions were conducted. Three stages were identified in the process of adherence: (1) Recognizing the Threat, (2) Taking Control, and (3) Managing for the Duration. Doing Our Part was identified as the core theme explaining the process of adherence, and involves the parent (or patient) taking responsibility for assuring that medications are taken as prescribed. Understanding the association between taking oral chemotherapy and control/cure of leukemia (Making the Connection) appeared to mediate adherence behaviors. PMID:21653911

    To compare tulobuterol patch and oral salbutamol sulfate in terms of efficacy and safety in children with mild or moderate acute attack of bronchial asthma. A total of 92 children with mild and moderate acute asthmatic attack were randomly divided into salbutamol group (n=46) and tulobuterol group (n=46). Both groups received routine treatment with antihistamine, selective leukotriene receptor antagonist and glucocorticoid. In addition, the salbutamol group was given slow-release capsules of salbutamol sulfate, and the tulobuterol group was treated with tulobuterol patch. The two groups were compared with respect to symptom scores of cough, wheeze, respiratory rate, wheezing sound, three depression sign and peak expiratory flow, as well as adverse events. As the treatment proceeded, symptom scores decreased in both groups; on the third day of treatment, all symptom scores except cough score showed a significant decrease in both groups (Pattack.

    Non-vitamin K antagonist oral anticoagulants (NOACs, dabigatran, rivaroxaban, apixaban, and edoxaban) have been increasingly used as alternatives to warfarin for stroke prophylaxis in patients with atrial fibrillation. Yet there is substantial lack of information on how patients on NOACs are currently treated when they have an acute ischemic stroke and the best strategies for treating intracerebral hemorrhage for those on chronic anticoagulation with warfarin or a NOAC. These are critical unmet needs for real world clinical decision making in these emergent patients. The ARAMIS Registry is a multicenter cohort study of acute stroke patients who were taking chronic anticoagulation therapy prior to admission and are admitted with either an acute ischemic stroke or intracerebral hemorrhage. Built upon the existing infrastructure of American Heart Association/American Stroke Association Get With the Guidelines Stroke, the ARAMIS Registry will enroll a total of approximately 10,000 patients (5000 with acute ischemic stroke who are taking a NOAC and 5000 with anticoagulation-related intracerebral hemorrhage who are on warfarin or a NOAC). The primary goals of the ARAMIS Registry are to provide a comprehensive picture of current treatment patterns and outcomes of acute ischemic stroke patients on NOACs, as well as anticoagulation-related intracerebral hemorrhage in patients on either warfarin or NOACs. Beyond characterizing the index hospitalization, up to 2500 patients (1250 ischemic stroke and 1250 intracerebral hemorrhage) who survive to discharge will be enrolled in an optional follow-up sub-study and interviewed at 3 and 6 months after discharge to assess longitudinal medication use, downstream care, functional status, and patient-reported outcomes. The ARAMIS Registry will document the current state of management of NOAC treated patients with acute ischemic stroke as well as contemporary care and outcome of anticoagulation-related intracerebral hemorrhage.

    Acute lower respiratory tract infection is common and often treated inappropriately in primary care with antibiotics. Corticosteroids are increasingly used but without sufficient evidence. To assess the effects of oral corticosteroids for acute lower respiratory tract infection in adults without asthma. Multicenter, placebo-controlled, randomized trial (July 2013 to final follow-up October 2014) conducted in 54 family practices in England among 401 adults with acute cough and at least 1 lower respiratory tract symptom not requiring immediate antibiotic treatment and with no history of chronic pulmonary disease or use of asthma medication in the past 5 years. Two 20-mg prednisolone tablets (n = 199) or matched placebo (n = 202) once daily for 5 days. The primary outcomes were duration of moderately bad or worse cough (0 to 28 days; minimal clinically important difference, 3.79 days) and mean severity of symptoms on days 2 to 4 (scored from 0 [not affected] to 6 [as bad as it could be]; minimal clinically important difference, 1.66 units). Secondary outcomes were duration and severity of acute lower respiratory tract infection symptoms, duration of abnormal peak flow, antibiotic use, and adverse events. Among 401 randomized patients, 2 withdrew immediately after randomization, and 1 duplicate patient was identified. Among the 398 patients with baseline data (mean age, 47 [SD, 16.0] years; 63% women; 17% smokers; 77% phlegm; 70% shortness of breath; 47% wheezing; 46% chest pain; 42% abnormal peak flow), 334 (84%) provided cough duration and 369 (93%) symptom severity data. Median cough duration was 5 days (interquartile range [IQR], 3-8 days) in the prednisolone group and 5 days (IQR, 3-10 days) in the placebo group (adjusted hazard ratio, 1.11; 95% CI, 0.89-1.39; P = .36 at an α = .05). Mean symptom severity was 1.99 points in the prednisolone group and 2.16 points in the placebo group (adjusted difference, -0.20; 95% CI, -0.40 to 0.00; P = .05

  16. Oral contrast for CT in patients with acute non-traumatic abdominal and pelvic pain: what should be its current role?

    2016-10-01

    Positive oral contrast agents, including barium suspensions and water-soluble iodinated solutions, have traditionally been used in conjunction with the CT evaluation of patients with abdominal and pelvic pain. Due to continued advancements in CT technology, and due to increasing obesity and correspondingly a general increase in the intra-abdominal and intra-pelvic fat separating bowel loops in North American patients and in patients in other parts of the world over the past few decades, the ability of radiologists to accurately evaluate the cause of acute symptoms has substantially improved. Recent research and evolving imaging society guidelines/systematic reviews increasingly support performing CT scans of the abdomen and pelvis without the need for positive oral contrast in these types of adult patient populations, in most clinical situations. Increased patient throughput, patient preference, patient safety, and most importantly, retention of high diagnostic accuracy, are reasons for this recent change in practice to routinely omit the use of enteric contrast agents for the majority of patients presenting with acute abdominal and pelvic pain whom are undergoing emergency CT.

    The objective of our study was to determine the effects of dehydration and oral rehydration on the incidence of acute adverse reactions to iodinated contrast media administered during abdominal and pelvic CT in outpatients. For our prospective randomized study performed at a single institution, adult outpatients undergoing contrast-enhanced abdominal CT were randomly divided into a rehydration group (n = 2244 patients [1379 men and 865 women]; mean age, 65.2 years; age range, 18-90 years) and a control group (n = 3715 [2112 male patients and 1603 female patients]; mean age, 65.8 years; age range, 17-96 years), which included an age- and sex-matched subgroup (adjusted control group, n = 2244). The rehydration group received an oral rehydration solution (500 mL of liquid in which osmotic pressure is adjusted to enhance gastrointestinal absorption) before abdominal and pelvic CT. Patients were also divided into subclinically dehydrated (n = 997) and hydrated (n = 4962) groups according to their answers to a questionnaire that they completed before the CT examination. The patients were interviewed about contrast-induced adverse reactions before they left the CT room, and the reactions were categorized as allergiclike or physiologic. The incidence of reactions was compared between the rehydration and control groups and between the subclinical dehydration and hydrated groups. The rehydration and control groups were compared with an unpaired t test or a chi-square or Fisher test. The overall incidence of an acute adverse reaction was 4.3% (254/5959); the acute adverse reactions included 136 allergiclike and 118 physiologic reactions. Fourteen allergiclike and nine physiologic reactions were moderate grade, and none was severe. There was no significant difference between the rehydration group and adjusted control group in the overall incidence of adverse reactions (99/2244 [4.4%] vs 100/2244 [4.5%], respectively; p = 0.9422) or between the subclinically dehydrated group

    Describe the treatment of patients with vaso-occlusive crises (VOC) in a Brazilian emergency department (ED) and the successful switch from intravenous to oral morphine. We analyzed records of 315 patients with sickle cell disease using two different protocols for pain: one in March 2010 prescribing intravenous morphine every 4 h throughout their stay, and another in March 2011 and 2012 prescribing one initial dose of intravenous morphine followed by equianalgesic doses of oral morphine every 4 h. Patients were triaged into three groups: mild, moderate, and severe VOC. The mild group was treated within 1 h after triage, the moderate within 30 min and the severe was treated immediately. Patients whose pain was not relieved within 6 h after the first dose of morphine were transferred into a different holding area of the ED where they continued to receive the same treatment for 48 h after which they were hospitalized if still in pain. The number of patients who stayed <24 h in the ED increased significantly from 63 in 2010 to 87 in 2012, and the number of admissions decreased from 26 in 2010 to 10 in 2012. The incidence of acute chest syndrome decreased from 8.5% in 2010 to 1.9% in 2012. Patients treated with oral morphine stayed a shorter time in the ED, had more pain relief, were admitted less frequently, and had less acute chest syndrome. These differences may be due to environmental, cultural, psychological, and pharmacogenetic factors. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    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.

    To assess the efficacy and safety of reduced osmolarity oral rehydration salts (ROORS) in treatment of mild to moderate dehydration caused by acute diarrhea in children. A multicenter, randomized, double-blind, positive drug controlled clinical trial was conducted in 125 cases aged 1 to 17 years. These children with acute diarrhea and signs of dehydration were randomly assigned to receive either ROORS (trial group, n = 62) or oral rehydration salts II (ORS II) (control group, n = 63). The volume of intravenous infusion were recorded. The improvements of systemic symtoms and signs, diarrhea, dehydration and total scores were compared between the two groups. The adverse events and changes of electrolyte and other laboratory tests during treatment were also observed and analyzed. The overall effective rates in trial group and control group were 96.8% and 96.8%, respectively. The recovery of systemic symptoms, dehydration signs and diarrhea occurred in 96%, 97% and 78% patients in trial groups, and 96%, 98% and 85% patients in control group. The scores of symptoms and signs in both groups decreased significantly after treatment. All the above parameters and the number of cases who needed intravenous infusion (41 vs. 39) were not statistically different between two groups. However, the average volume of intravenously infused fluids in trial group was (450.98 +/- 183.07) ml, 24.5% less than that in the control group (597.30 +/- 343.37) ml (P 0.05). A case in trial group had mild abdominal distention and recovered spontaneously. ROORS was shown to be effective and safe in the treatment of mild and moderate dehydration induced by acute diarrhea. Compared to ORS II, ROORS could decrease the intravenous supplement of fluid and lower the risk of hypernatremia.

    Morphologic and functional alternations of the pancreas following acute pancreatitis were studied in 29 patients. At the time of attack a diagnosis of acute pancreatitis had been confirmed by laparotomy in 27 cases, and by clinical picture and by serum amylase levels in 2 cases. The average duration of follow up was 56.3 months. Normal images were obtained in 17 of 29 cases. According to secretin tests, 4 of these had slight to moderately decreased exocrine function; the test were within normal limits. 12 cases with normal image had abnormal oral glucose tolerance curves similar to those fund in mild to moderate diabetes. 10 of the 12 cases with abnormal scintigrams showed decreased isotope uptake in all or part of the pancreas, while 2 showed no uptake at all. These changes were mast apparent in the tail of the pancreas. Ten of the 12 cases with abnormal images had some degree of decreased exocrine function. All 12 had the abnormal GTT curve of diabetes, 4 who had severe diabetes with markedly decreased exocrine function and poor image of the pancreas. In 4 cases the histopathological findings obtained at the time of laparotomy, were shown to be very consistent with the scintigraphic features. It was demonstrated by both scintigraphs and function tests that the alcoholic factor plays a very important role in the prognosis of acute pancreatitis. Acute pancreatitis resulted in chronic pancreatitis in 4 cases, (14 %) of the remaining 8 cases with abnormal scintigram, it is postulated that the inflamatory process subsided allowing time for cicatrical fibrosis to occur.

    Oral anticoagulation therapy is recommended for the prevention of recurrent ischemic stroke in patients with atrial fibrillation (AF). Current guidelines do not provide evidence-based recommendations on optimal time-point to start anticoagulation therapy after an acute ischemic stroke. Non-vitamin K antagonist oral anticoagulants (NOACs) may offer advantages compared to warfarin because of faster and more predictable onset of action and potentially a lower risk of intracerebral haemorrhage also in the acute phase after an ischemic stroke. The TIMING study aims to establish the efficacy and safety of early vs delayed initiation of NOACs in patients with acute ischemic stroke and AF. The TIMING study is a national, investigator-led, registry-based, multicentre, open-label, randomised controlled study. The Swedish Stroke Register is used for enrolment, randomisation and follow-up of 3000 patients, who are randomised (1:1) within 72 h from ischemic stroke onset to either early (≤ 4 days) or delayed (≥ 5-10 days) start of NOAC therapy. The primary outcome is the composite of recurrent ischemic stroke, symptomatic intracerebral haemorrhage, or all-cause mortality within 90 days after randomisation. Secondary outcomes include: individual components of the primary outcome at 90 and 365 days; major haemorrhagic events; functional outcome by the modified Rankin Scale at 90 days; and health economics. In an optional biomarker sub-study, blood samples will be collected after randomisation from approximately half of the patients for central analysis of cardiovascular biomarkers after study completion. The study is funded by the Swedish Medical Research Council. Enrolment of patients started in April 2017. The TIMING study addresses the ongoing clinical dilemma of when to start NOAC after an acute ischemic stroke in patients with AF. By the inclusion of a randomisation module within the Swedish Stroke Register, the advantages of a prospective randomised study design

    Twenty-five rhesus monkeys were randomly assigned to one of five mouth irradiation treatment schedules: control group, no irradiation; 60 Co γ five times weekly; 60 Co twice weekly; 16-MeV/sub d→Be/ neutrons twice weekly. Although the acute reactions of the oral mucosa were similar in the four irradiated groups, the late sequelae were more severe in the animals irradiated twice weekly with 60 Co γ or neutrons. All of the animals irradiated with 60 Co γ twice weekly or with 16 MeV/sub d→Be/ neutrons exhibited oromucosal necrosis, whereas none of those irradiated five times weekly with 60 Co γ did. The difference in the effect of photon fractionation on early and late radiation sequelae may be related to different patterns of redistribution of surviving cells through the division cycle in tissues responsible for early and late damage.

    Older patients with acute myeloid leukemia (AML) have worse rates of complete remission and shorter overall survival than younger patients. The epigenetic modifier CC-486 is an oral formulation of azacitidine with promising clinical activity in patients with AML in Phase I studies. The Phase III, randomized, double-blind, placebo-controlled QUAZAR AML Maintenance trial (CC-486-AML-001) examines CC-486 maintenance therapy (300 mg/day for 14 days of 28-day treatment cycles) for patients aged ≥55 years with AML in first complete remission. The primary end point is overall survival. Secondary end points include relapse-free survival, safety, health-related quality of life and healthcare resource utilization. This trial will investigate whether CC-486 maintenance can prolong remission and improve survival for older patients with AML.

    Recently, new concerns on the safety profile of nonsteroidal anti-inflammatory drugs (NSAIDs) have been raised by the European Medicines Agency (EMEA) and other regulatory authorities. The safety profile of oral dexketoprofen trometamol for the treatment of acute mild to moderate pain of different causes in actual conditions of use in the primary care setting was assessed. A prospective cohort study was designed to evaluate the tolerability of dexketoprofen compared with other commonly prescribed analgesics. Medications were given according to specifications in the summary of product characteristics. The intensity of pain was assessed at baseline and at days 1 and 7 of drug treatment using a 100-mm visual analog scale (VAS). Adverse events (AEs) were recorded. A total of 7,337 patients (median age [IQR] = 46 [33-61] years) were included in the study comparing dexketoprofen (n = 5,429), diclofenac (n = 485), ibuprofen (n = 479), paracetamol (n = 459), metamizole (n = 207), aceclofenac (n = 103), naproxen (n = 74), piroxicam (n = 69) and dexibuprofen (n = 32). The reasons for use were: musculoskeletal disorders, headache, dysmenorrhea and odontalgia. Treatment compliance was very high. Metamizole-paracetamol and dexketoprofen showed the lowest prevalence of AEs (2.7% and 3.6%, respectively), while aceclofenac-diclofenac showed the highest prevalence (8.2%) (P dexketoprofen, 1.57 (0.79-3.13) for ibuprofen and dexibuprofen, 2.31 (0.64-8.27) for naproxen, 2.63 (0.85-8.15) for piroxicam and 3.37 (1.87-6.06) for aceclofenac-diclofenac. These results confirm the safety of oral treatment with dexketoprofen in patients with acute pain of various etiologies observed in previous studies and support the use of dexketoprofen as a first-line drug for the approved therapeutic indications.

    Full Text Available Since 1992, surveillance for acute flaccid paralysis (AFP cases was introduced in Malaysia along with the establishment of the National Poliovirus Laboratory at the Institute for Medical Research. In 2008, the Ministry of Health, Malaysia, approved a vaccine policy change from oral polio vaccine to inactivated polio vaccine (IPV. Eight states started using IPV in the Expanded Immunization Programme, followed by the remaining states in January 2010. The objective of this study was to determine the viral aetiology of AFP cases below 15 years of age, before and after vaccine policy change from oral polio vaccine to inactivated polio vaccine. One hundred and seventy-nine enteroviruses were isolated from the 3394 stool specimens investigated between 1992 and December 2012. Fifty-six out of 107 virus isolates were polioviruses and the remaining were non-polio enteroviruses. Since 2009 after the sequential introduction of IPV in the childhood immunization programme, no Sabin polioviruses were isolated from AFP cases. In 2012, the laboratory AFP surveillance was supplemented with environmental surveillance with sewage sampling. Thirteen Sabin polioviruses were also isolated from sewage in the same year, but no vaccine-derived poliovirus was detected during this period.

    Dose–response curves (DRCs) and the quantitative parameters describing these curves were generated for grade 3 oral mucositis and dysphagia in 144 patients using individual patient DVHs. Curve fits to the oral mucositis clinical data yielded parameter values of mean dose in 2 Gy equivalent, MD 50 = 51 Gy (95% CI 40–61), slope of the curve, k = 1(95% CI 0.6–1.5). R 2 value for the goodness of fit was 0.80. Fits to the grade 3 dysphagia clinical data yielded parameter values of MD 50 = 44.5 Gy (95% CI 36–53), k = 2.6 (95% CI 0.8–4.5). R 2 value for the goodness of fit was 0.65. This is the first study to derive DRCs in patients receiving induction chemotherapy followed by chemo-radiation (IC-C-IMRT) for head and neck cancer. The dose–response model described in this study could be useful for comparing acute mucositis rates for different dose–fractionation schedules when using IMRT for head and neck cancer.

    Full Text Available Amphimas pterocarpoides Harms (Leguminosae is widely used traditionally in Central and West Africa for the treatment of various ailments. However, no data regarding its safety have been published until now. Thus, the present study aimed to investigate the potential toxicity of the methanol extract of the stem bark of Amphimas pterocarpoides (AP in Wistar rats following the OECD guidelines. In acute oral toxicity, female rats received a single dose of 2000 mg/kg of AP and were observed for 14 days. In subchronic toxicity, doses of 150, 300, 600 mg/kg/day of AP were given per os to rats (males and females for 28 days. No death and abnormal behaviors were observed in acute toxicity and the LD50 was estimated higher than 5000 mg/kg. In the subchronic study, AP induced no significant variation in body weight and relative weight of organs, whereas a delayed decrease of white blood cell count and granulocytes was observed. Inconsistent increase of the total cholesterol/high density lipoprotein was observed at 600 mg/kg in males. Such variation (not dose dependent and without biological relevance indicate a wide margin of safety for the traditional use of AP.

    Full Text Available Anthocyanins are flavonoids which demonstrated biological activities in in vivo and in vitro models. Here in the anti-inflammatory properties of an anthocyanin-enriched fraction (AF extracted from wild mulberry and the cyanidin-3-glucoside (C3G, the most abundant anthocyanin in diet, were studied in two acute inflammation experimental models, in the peritonitis and in the paw oedema assays, both of which were induced by carrageenan (cg in mice. In each trial, AF and C3G (4 mg/100 g/animal were orally administered in two distinct protocols: 30 min before and 1 h after cg stimulus. The administration of both AF and C3G suppresses the paw oedema in both administration times (P<0.05. In the peritonitis, AF and C3G reduced the polymorphonuclear leukocytes (PMN influx in the peritoneal exudates when administered 1 h after cg injection. AF was more efficient reducing the PMN when administered 30 min before cg. Both AF and C3G were found to suppress mRNA as well as protein levels of COX-2 upregulated by cg in both protocols, but the inhibitory effect on PGE2 production in the peritoneal exudates was observed when administered 30 min before cg (P<0.05. Our findings suggest that AF and C3G minimize acute inflammation and they present positive contributions as dietary supplements.

    Background: The development of drug delivery systems has improved the therapeutic and toxic properties of existing drugs in therapy. Microemulsion systems are novel vehicles for drug delivery, which have been developed in recent years. These systems are currently of interest to the pharmaceutical scientist because of their considerable potential to act as drug delivery vehicles by incorporating into a wide range of drug molecules. Although these systems improved solubility and bioavailability of drugs, they may have potential toxic effects on the body organs. Objectives: The purpose of this study was to examine a possible hepatotoxic and nephrotoxic effect of lithium carbonate microemulsion (LCME) in a mice model. Materials and Methods: Eighty male Swiss albino mice were randomly allocated to eight experimental groups, as follows: Group 1, as negative control group were treated orally with normal saline (0.9% NaCl); Group 2, received microemulsion base without drug as control group; Groups 3 to 5, received lithium carbonate (LC) solution in doses of 50, 100, and 200 mg/kg, respectively; Groups 6 to 8, received LCME orally in doses of 50, 100, and 200 mg/kg, respectively. All drugs were administered orally for ten consecutive days. Serum glutamate pyruvate aminotransferase (SGPT), serum glutamate oxaloacetate aminotransferase (SGOT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), and plasma creatinine (Cr), as markers of liver and kidney toxicity in treated mice, were measured. Furthermore, the changes of tissue were assessed by histopathologic examination. Results: The findings showed that serum activity of ALP, SGOT, and SGPT and the levels of BUN and Cr in microemulsion base group was greater than normal saline group. However, this difference was not significant. Administration of LC and LCME in all doses resulted in a significant increase in the levels of BUN and serum activity of SGOT and SGPT in comparison to normal saline group (P < 0

    The extract prepared from dried seeds of Cucurbita maxima was administered to rats and pigs. Following a single dose or 4 weeks of daily oral administration, the extract produced no changes in serum glucose, urea, creatinine, total protein, uric acid, GOT, GPT, LDH or blood counts. Urine analysis (urea, uric acid, creatinine, total protein, Na and K), as well as histopathological investigation, showed no abnormalities. These results taken as a whole indicate that the seeds of C. maxima as used in Brazilian folk medicine are not toxic for rats and swine.

    Atrial natriuretic peptide (ANP) is primarily seen as a hormone involved in salt and water homeostasis and blood pressure regulation. Evidence supports a link between metabolism and ANP. Circulating ANP concentrations are low in obese individuals with insulin resistance and hyperinsulinemia....... The dynamic relationship between insulin and ANP has been sparsely studied. We therefore measured circulating concentrations of midregional proatrial natriuretic peptide (MR-proANP), a stable marker of ANP secretion, and insulin in lean and obese men during an oral glucose challenge. One hundred and three...... obese men (body mass index (BMI) ≥30.0 kg/m2) were compared with 27 lean men (BMI = 20.0-24.9 kg/m2). During a 75 g oral glucose challenge, circulating concentrations of MR-proANP and insulin were measured at baseline and every half hour for 2 h. Fasting MR-proANP concentrations were lower in the obese...

    Acute lymphoblastic leukemia (ALL), accounting for 23% of all malignancies in children, is the most prevalent pediatric malignancy. This study compared dental caries, oral hygiene status, salivary pH, and Streptococcus mutans counts in dental plaques and saliva of children with leukemia with those of healthy controls. This case-control cross-sectional study assessed 32 children with ALL and 32 healthy children (4-9-year-old) for gingival bleeding index (GBI), decayed, missing, and filled/decayed, missing, and filled surfaces (DMF/dmfs), and plaque index (PI). Sampling was performed to determine salivary pH and S. mutans counts of the participants. The two groups matched in terms of age, gender, and socioeconomic status. The groups were compared using independent t-test, Mann-Whitney test, Chi-square test, and Spearman's and Pearson's correlation analyses. The mean DMF/dmfs and GBI were significantly higher in the ALL group (P DMF / dmfs = 0.03; P GBI = 0.04). However, the two groups were not significantly different in the mean PI values ( P = 0.47). The mean S. mutans counts in dental plaques and saliva of the children with leukemia were significantly lower than the healthy controls ( P salivary pH was significantly lower in the ALL group compared to the control group ( P salivary pH, and cumulative effects of other risk factors highlight the significance of oral hygiene training programs (for the parents of these children) and regular dental examinations for these children.

    We conducted a retrospective analysis to compare outcomes in adult patients with acute lymphoblastic leukemia (ALL) who underwent allogeneic hematopoietic cell transplantation (allo-HCT) with conditioning regimens containing cyclophosphamide (CY) in combination with total body irradiation (TBI), oral busulfan (p.o. BU), or intravenous busulfan (i.v. BU). We used data for January 2000 to December 2012 from the Transplant Registry Unified Management Program of the Japan Society of Hematopoietic Cell Transplantation. We identified 2130 patients treated with TBI/CY (n = 2028), p.o. BU/CY (n = 60), or i.v. BU/CY (n = 42). Two-year overall survival (OS) and 2-year relapse-free survival rates were 69.0% and 62.1%, respectively, in the TBI/CY group, 55.9% and 54.2% in the p.o. BU/CY group, and 71.0% and 46.8% in the i.v. BU/CY group. In multivariate analysis, compared with TBI/CY, p.o. BU/CY, but not i.v. BU/CY, was associated with lower OS (hazard ratio [HR], 1.46; P = .047) and a higher incidence of sinusoidal obstruction syndrome (HR, 3.36; P = .030). No between-group differences were seen in the incidence of nonrelapse mortality, relapse, acute graft-versus-host disease (GVHD), or chronic GVHD. We suggest that i.v. BU/CY might be a possible alternative allo-HCT conditioning regimen for adults with ALL who are not suitable for TBI. Copyright © 2016 The American Society for Blood and Marrow Transplantation.

    The most abused illicit drug in both the developing and the developed world is Cannabis disposing users to varying forms of personality disorders. However, the effects of cannabis on cortico-hippocampal architecture and cognitive behaviours still remain elusive.  The present study investigated the neuro-cognitive implications of oral cannabis use in rats. Eighteen adult Wistar rats were randomly grouped to three. Saline was administered to the control rats, cannabis (20 mg/kg) to the experimental group I, while Scopolamine (1 mg/kg. ip) was administered to the last group as a standard measure for the cannabis induced cognitive impairment. All treatments lasted for seven consecutive days. Open Field Test (OFT) was used to assess locomotor activities, Elevated Plus Maze (EPM) for anxiety-like behaviour, and Y maze paradigm for spatial memory and data subjected to ANOVA and T test respectively. Thereafter, rats were sacrificed and brains removed for histopathological studies. Cannabis significantly reduced rearing frequencies in the OFT and EPM, and increased freezing period in the OFT. It also reduced percentage alternation similar to scopolamine in the Y maze, and these effects were coupled with alterations in the cortico-hippocampal neuronal architectures. These results point to the detrimental impacts of cannabis on cortico-hippocampal neuronal architecture and morphology, and consequently cognitive deficits.

A bespoke BI analysis was undertaken in addition to detailed scenario analyses with respect to critical model structure components.Results: According to the CU model, the intervention is less costly and more effective than comparator for the base case with a dominant incremental cost-effectiveness ratio of –RM 1,272,833/quality-adjusted life year (USD –312,726/quality-adjusted life year in favor of the intervention. According to the BI analysis (assuming an increase of 5% market share per year for racecadotril+ORS for 5 years, the total cumulative incremental percentage reduction in health care expenditure for diarrhea in children is 0.136578%, resulting in a total potential cumulative cost savings of –RM 73,193,603 (USD –17,983,595 over a 5-year period. Results hold true across a range of plausible scenarios focused on critical model components.Conclusion: Adjuvant racecadotril vs ORS alone is potentially cost-effective from a Malaysian public payer perspective subject to the assumptions and limitations of the model. BI analysis shows that this translates into potential cost savings for the Malaysian public health care system. Results hold true at evidence-based base

    Full Text Available A kind of chemically cross-linked pH-sensitive hydrogels based on methoxyl poly(ethylene glycol-poly(caprolactone-acryloyl chloride (MPEG-PCL-AC, PECA, poly(ethylene glycol methyl ether methacrylate (MPEGMA, MEG, N,N-methylenebisacrylamide (BIS, and itaconic acid (IA were prepared without using any organic solvent by heat-initiated free radical method. The obtained macromonomers and hydrogels were characterized by 1H NMR and FT-IR, respectively. Morphology study of hydrogels was also investigated in this paper, and it showed that the hydrogels had good pH-sensitivity. The acute toxicity test and histopathological study were conducted in BALB/c mice. The results indicated that the maximum tolerance dose of the hydrogel was higher than 10000 mg/kg body weight. No morality or signs of toxicity were observed during the whole 7-day observation period. Compared to the control groups, there were no important adverse effects in the variables of hematology routine test and serum chemistry analysis both in male or female treatment group. Histopathological study also did not show any significant lesions, including heart, liver, lung, spleen, kidney, stomach, intestine, and testis. All the results demonstrated that this hydrogel was nontoxic after gavage. Thus, the hydrogel might be the biocompatible potential candidate for oral drug delivery system.

    The acute oral toxicity of 1-palmitoyl-3-chloropropanediol (3-MCPD 1-monopalmitate) and 1,2-bis-palmitoyl-3-chloropropanediol (3-MCPD dipalmitate) in Swiss mice were examined, along with their cytotoxicity in NRK-52E rat kidney cells. LD50 (median lethal dose) value of 3-MCPD 1-monopalmitate was determined 2676.81 mg/kg body weight (BW). The results showed that 3-MCPD 1-monopalmitate dose-dependently decreased the mean body weight, and caused significant increase of serum urea nitrogen and creatinine in dead mice compared to the control and survived mice. Major histopathological changes in mice fed 3-MCPD 1-monopalmitate were renal tubular necrosis, protein casts and spermatids decrease in the seminiferous tubules. According to the limit test for 3-MCPD dipalmitate, LD50 value of 3-MCPD dipalmitate was presumed to be greater than 5000 mg/kg BW. Obvious changes were not observed on mean body weight, absolute and relative organ weight or serum urea nitrogen and creatinine levels in mice fed 3-MCPD dipalmitate. However, renal tubular necrosis, protein casts and spermatids decrease were also observed in the dead mice. In addition, MTT and LDH assay results only showed the cytotoxicity of 3-MCPD 1-monopalmitate in NRK-52E rat kidney cells in a dose-dependent manner. Together, the results indicated a greater toxicity of 3-MCPD 1-monopalmitate compared to 3-MCPD dipalmitate. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Though nanomaterials (NMs) are being utilized worldwide, increasing use of NMs have raised concerns over their safety to human health and environment. Iron oxide (Fe{sub 2}O{sub 3}) NMs have important applications. The aim of this study was to assess the genotoxicity of Fe{sub 2}O{sub 3}-30 nm and Fe{sub 2}O{sub 3}-bulk in female Wistar rats. Fe{sub 2}O{sub 3}-30 nm was characterized by using transmission electron microscopy, dynamic light scattering, laser Doppler velocimetry and surface area analysis. The rats were treated orally with the single doses of 500, 1000, 2000 mg/kg bw of Fe{sub 2}O{sub 3}-30 nm and Fe{sub 2}O{sub 3} –bulk. The genotoxicity was evaluated at 6, 24, 48 and 72 h by the comet assay in leucocytes, 48 and 72 h by micronucleus test (MNT) in peripheral blood cells, 18 and 24 h by chromosomal aberration (CA) assay and 24 and 48 h by MNT in bone marrow cells. The biodistribution of iron (Fe) was carried out at 6, 24, 48 and 72 h after treatment in liver, spleen, kidney, heart, brain, bone marrow, urine and feces by using atomic absorption spectrophotometry. The % tail DNA, frequencies of micronuclei and CAs were statistically insignificant (p > 0.05) at all doses. These results suggest that Fe{sub 2}O{sub 3}-30 nm and Fe{sub 2}O{sub 3}-bulk was not genotoxic at the doses tested. Bioavailability of Fe was size and dose dependent in all the tissues from the groups exposed to Fe{sub 2}O{sub 3}-30 nm. Fe{sub 2}O{sub 3} NMs were able to enter in the organs and the rats are biocompatible with much higher concentration of Fe. However, the accumulated Fe did not cause significant genotoxicity. This study provides additional knowledge about the toxicology of Fe{sub 2}O{sub 3} NMs. -- Highlights: ► Fe{sub 2}O{sub 3}-30 nm and Fe{sub 2}O{sub 3}-bulk were orally administered to rats with single doses. ► The nano and bulk Fe{sub 2}O{sub 3} showed insignificant results with MNT, comet and CA assays. ► The bulk was excreted via feces whereas the NMs

    The aim of this study was to investigate the association between the susceptibility of severe oral mucositis (OM) in Chinese nasopharyngeal carcinoma (NPC) patients treated with radiotherapy and single nucleotide polymorphisms (SNPs) across the whole genome. SNPs were screened in a total of 24 patients with NPC and an additional 6 were subjected to mRNA expression analysis. Patients were subdivided into CTC 0-2 (CTC toxicity grade 0, 1, and 2) and CTC 3+ (CTC toxicity grade 3 and above) groups according to their CTC (common toxicity criteria) scores. The GTEx dataset was used to performed eQTL analyses and in-vitro functional assays were performed for eQTL-associated genes. Our data identified 7 functional SNPs associated with the development of OM. We observed that rs11081899-A, located in the 5′-UTR of the ZNF24 gene, was significantly correlated with a higher risk of severe mucositis (OR = 14.631, 95% CI = 2.61-105.46, p = 1.2 × 10−4), and positively associated with ZNF24 mRNA expression (p = 4.1 × 10−6) from GTEx dataset. In addition, high ZNF24 mRNA expression was associated with severe OM in patients with NPC (p = 0.02). Further functional assays revealed that ZNF24 knockdown reduced p65 expression and suppressed TNF-α-induced NF-κB activation and pro-inflammatory cytokines release. These findings suggested that rs11081899-A may be a genetic susceptibility factor for radiation-induced OM in patients with NPC, although its value in clinical application needs to be further verified in a large cohort. Also, we suggested that downregulation of ZNF24 may attenuate the development of mucositis by suppressing NF-κB activation. PMID:28968968

    Fusidic acid is an oral antistaphylococcal antibiotic that has been used in Europe for more than 40 years to treat skin infections as well as chronic bone and joint infections. It is a steroidal antibiotic and the only marketed member of the fusidane class. Fusidic acid inhibits protein synthesis by binding EF-G-GDP, which results in the inhibition of both peptide translocation and ribosome disassembly. It has a novel structure and novel mode of action and, therefore, there is little cross-resistance with other known antibiotics. Many mutations can occur in the FusA gene that codes for EF-G, and some of these mutations can result in high-level resistance (minimum inhibitory concentration [MIC] > 64 mg/L), whereas others result in biologically unfit staphylococci that require compensatory mutations to survive. Low-level resistance (<8 mg/L) is more common and is mediated by fusB, fusC, and fusD genes that code for small proteins that protect EF-G-GDP from binding fusidic acid. The genes for these proteins are spread by plasmids and can be selected mostly by topical antibiotic use. Reports of resistance have led to combination use of fusidic acid with rifampin, which is superseded by the development of a new dosing regimen for fusidic acid that can be used in monotherapy. It consists of a front-loading dose to decrease the potential for resistance development followed by a maintenance dose. This dosing regimen is now being used in clinical trials in the United States for skin and refractory bone and joint infections. PMID:26729758

    As titanium dioxide nanoparticles (TiO2 NPs) are widely used commercially, their potential toxicity on human health has attracted particular attention. In the present study, the oral toxicological effects of TiO2 NPs (dosed at 0.16, 0.4 and 1 g kg - 1, respectively) were investigated using conventional approaches and metabonomic analysis in Wistar rats. Serum chemistry, hematology and histopathology examinations were performed. The urine and serum were investigated by 1H nuclear magnetic resonance (NMR) using principal components and partial least squares discriminant analysis. The metabolic signature of urinalysis in TiO2 NP-treated rats showed increases in the levels of taurine, citrate, hippurate, histidine, trimethylamine-N-oxide (TMAO), citrulline, α-ketoglutarate, phenylacetylglycine (PAG) and acetate; moreover, decreases in the levels of lactate, betaine, methionine, threonine, pyruvate, 3-D-hydroxybutyrate (3-D-HB), choline and leucine were observed. The metabonomics analysis of serum showed increases in TMAO, choline, creatine, phosphocholine and 3-D-HB as well as decreases in glutamine, pyruvate, glutamate, acetoacetate, glutathione and methionine after TiO2 NP treatment. Aspartate aminotransferase (AST), creatine kinase (CK) and lactate dehydrogenase (LDH) were elevated and mitochondrial swelling in heart tissue was observed in TiO2 NP-treated rats. These findings indicate that disturbances in energy and amino acid metabolism and the gut microflora environment may be attributable to the slight injury to the liver and heart caused by TiO2 NPs. Moreover, the NMR-based metabolomic approach is a reliable and sensitive method to study the biochemical effects of nanomaterials.

    Intermediate-high risk pulmonary embolism (IHR-PE) has a poor prognosis, but is under-represented in trials of direct oral anticoagulants (DOACs) in venous thromboembolic disease (VTE). We aimed to assess whether the administration of DOACs was equivalent to the conventional (CONV) treatment of low-molecular weight heparin bridged with warfarin for treating IHR-PE. We conducted a retrospective cohort study including 59 consecutive patients admitted with IHR-PE and followed for up to three months after discharge. Two groups were created based on the anticoagulant strategy: CONV (n=35) and DOAC (n=24). The efficacy endpoints were death, recurrent PE, estimated pulmonary artery systolic pressure (PASP), right ventricular systolic function (RVSF) at discharge, and length of stay; the safety endpoint was major bleeding. The two groups were similar regarding demographics, PE etiology and markers of clinical severity. There were four in-hospital deaths in the CONV group and none in the DOAC group. No recurrent PE or major bleeding event was recorded in either group. At discharge, neither PASP nor RVSF was different between the groups. Patients in the DOAC group were discharged 1.7 days earlier on average than patients in the CONV group (4.7±2.4 vs. 3.0±1.5 days, p=0.002). The adoption of a DOAC treatment strategy in this real-world cohort of IHR-PE patients was associated with similar efficacy and safety to the CONV approach. The fact that monitoring of anticoagulation effect was unnecessary probably led to the significant reduction in length of stay. Copyright © 2017 Sociedade Portuguesa de Cardiologia.

Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media.Methods: We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®, and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product.Results: The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90% and/or acute otitis media (about 40%, calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period

    The treatment duration of acute uncomplicated pyelonephritis (AUP) is still under debate. As shortening treatment duration could be a means to reduce antimicrobial resistance, we aimed to establish whether 5 days of antibiotic treatment is non-inferior to 10 days in patients with AUP. We performed an open-label prospective randomized trial comparing 5 days to 10 days of fluoroquinolone treatment for AUP. The inclusion criteria were: female patients aged ≥18 years with clinical signs of urinary tract infection, fever >38 °C, and positive urinalysis. Patients were randomized to either 5 or 10 days of fluoroquinolone treatment. Outcome was cure at day 10 and day 30 after the end of treatment. One hundred patients were randomized and 12 were excluded after randomization. The mean ± standard deviation (SD) age was 31.8 ± 11 years old and the mean ± SD temperature was 38.6 ± 0.7 °C. The main bacterium involved was Escherichia coli (n = 86; 97.7%) and 3 (3.4%) patients had a positive blood culture. In the post-hoc analysis, clinical cure 10 days after the end of the treatment was 28/30 (93.3%) in the 5-day arm and 36/38 (94.7%) in the 10-day arm (p = 1.00). At day 30, the clinical cure rate was 23/23 (100%) in the 5-day arm and 20/20 (100%) in the 10-day arm (p = 1.00). The microbiological cure rate was 20/23 (87.0%) in the 5-day arm and 16/20 (80.0%) in the 10-day arm (p = 1.00). The efficacy of 5 days of fluoroquinolone treatment does not seem different from 10 days of treatment for AUP.

    Full Text Available Several oral nonsteroidal anti-inflammatory drugs (NSAIDs are effective to treat migraine attacks. Lysine clonixinate (LC is a NSAID derived from nicotinic acid that has proven to be effective in various pain syndromes such as renal colic and muscular pain. The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of oral LC compared to placebo in the acute treatment of migraine. Sixty four patients with the diagnosis of migraine, according to the IHS criteria, were studied prospectively. Patients received LC or placebo once the headache reached moderate or severe intensity for 6 consecutive attacks. With regard to the moderate attacks, LC was superior than placebo after 1, 2 and 4 hours. The consumption of other rescue medications after 4 hours was significantly higher in the placebo group. With regard to the severe attacks, there was no difference between the active drug group and the placebo group concerning headache intensity and consumption of other rescue medications. We conclude that the NSAID lysine clonixinate is effective in treating moderately severe migraine attacks. It is not superior than placebo in treating severe migraine attacks.Alguns antinflamatórios não esteroidais (AINEs são eficazes para o tratamento de crises de migrânea. O clonixinato de lisina (CL é um AINE derivado do ácido nicotínico comprovadamente eficaz no tratamento de várias síndromes dolorosas como a cólica renal e a dor muscular. O objetivo deste estudo duplo-cego placebo-controlado foi avaliar a eficácia do CL oral comparado ao placebo no tratamento agudo da migrânea. Sessenta e quatro pacientes com o diagnóstico de migrânea, de acordo com os critérios da Sociedade Internacional de Cefaléia (IHS, foram estudados prospectivamente. Os pacientes receberam CL ou placebo quando a cefaléia atingiu a intensidade moderada ou severa em 6 crises consecutivas. Para as crises moderadas, o CL foi superior ao placebo em 1, 2 e 4

    Background and Aims: Preemptive analgesia is an antinociceptive treatment that prevents establishment of altered processing of afferent input. Pregabalin has been claimed to be more effective in preventing neuropathic component of acute nociceptive pain of surgery. We conducted a study to compare the effect of oral gabapentin and pregabalin with control group for post-operative analgesia Materials and Methods: A total of 90 ASA grade I and II patients posted for elective gynecological surgeries were randomized into 3 groups (group A, B and C of 30 patients each). One hour before entering into the operation theatre the blinded drug selected for the study was given with a sip of water. Group A- received identical placebo capsule, Group B- received 600mg of gabapentin capsule and Group C — received 150 mg of pregabalin capsule. Spinal anesthesia was performed at L3-L4 interspace and a volume of 3.5 ml of 0.5% bupivacaine heavy injected over 30sec through a 25 G spinal needle. VAS score at first rescue analgesia, mean time of onset of analgesia, level of sensory block at 5min and 10 min interval, onset of motor block, total duration of analgesia and total requirement of rescue analgesia were observed as primary outcome. Hemodynamics and side effects were recorded as secondary outcome in all patients. Results: A significantly longer mean duration of effective analgesia in group C was observed compared with other groups (P < 0.001). The mean duration of effective analgesia in group C was 535.16 ± 32.86 min versus 151.83 ± 16.21 minutes in group A and 302.00 ± 24.26 minutes in group B. The mean numbers of doses of rescue analgesia in the first 24 hours in group A, B and C was 4.7 ± 0.65, 4.1 ±0.66 and 3.9±0.614. (P value <0.001). Conclusion: We conclude that preemptive use of gabapentin 600mg and pregabalin 150 mg orally significantly reduces the postoperative rescue analgesic requirement and increases the duration of postoperative analgesia in patients undergoing

    Thrombolytic therapy has become the treatment of choice for patients with acute myocardial infarction. Researchers are not yet able to identify patients with salvage of myocardium who are at risk for recurrent coronary events. Thus, a prospective trial was performed in 46 patients with myocardial infarction (28 anterior and 18 inferior) who received thrombolytic therapy to determine if early thallium tomography (4.7 days) using oral dipyridamole would identify more patients with residual ischemia than early symptom-limited exercise treadmill tests (5.5 days). There were no complications during the exercise treadmill tests or oral dipyridamole thallium tomography. Mean duration of exercise was 11 +/- 3 minutes and the peak heart rate was 126 beats/min. Thirteen patients had positive test results. After oral dipyridamole all patients had abnormal thallium uptake on the early images. Positive scans with partial filling in of the initial perfusion defects were evident in 34 patients. Angina developed in 13 patients and was easily reversed with intravenous aminophylline. Both symptom-limited exercise treadmill tests and thallium tomography using oral dipyridamole were safely performed early after myocardial infarction in patients receiving thrombolytic therapy. Thallium tomography identified more patients with residual ischemia than exercise treadmill tests (74 vs 28%). Further studies are required to determine whether the results of thallium tomography after oral dipyridamole can be used to optimize patient management and eliminate the need for coronary angiography in some patients

    Higenamine, also known as norcoclaurine, is an herbal constituent thought to act as a beta-2 adrenergic receptor agonist-possibly stimulating lipolysis. It was the purpose of this study to determine the impact of a higenamine-based dietary supplement on plasma free fatty acids and energy expenditure following acute oral ingestion. Sixteen healthy subjects (8 men; 26.1 ± 2.5 yrs; 8 women 22.4 ± 3.1 yrs) ingested a dietary supplement containing a combination of higenamine, caffeine (270 mg), and yohimbe bark extract or a placebo, on two separate occasions in a double-blind, randomized, cross-over design, separated by 6-8 days. Blood samples were collected immediately before ingestion, and at 30, 60, 120, and 180 minutes post ingestion, and analyzed for plasma free fatty acids (FFA) and glycerol. Breath samples were collected at the same times for a measure of kilocalorie expenditure and respiratory exchange ratio (RER) using indirect calorimetry. Heart rate and blood pressure were recorded at all times. Data collection occurred in the morning following a 10 hour overnight fast. A condition effect was noted for both FFA (p 0.05). A condition effect was noted for heart rate (p = 0.03) and systolic blood pressure (p < 0.0001), with values higher for supplement compared to placebo. Ingestion of a higenamine-based dietary supplement stimulates lipolysis and energy expenditure, as evidenced by a significant increase in circulating FFA and kilocalorie expenditure. The same supplement results in a moderate increase in heart rate (~3 bpm) and systolic blood pressure (~12 mmHg), which is consistent with previous studies evaluating moderate doses of caffeine and yohimbine, suggesting that higenamine contributes little to the increase in these hemodynamic variables. These findings are in reference to young, healthy and active men and women.

    Full Text Available Medicinal plants have been used in medicoculturally diverse countries around the world, where it is a part of a time-honoured tradition that is respected even today. Polyalthia longifolia leaf extract has been previously reported as an efficient antioxidant in vitro. Hence, the genotoxic effects of P. longifolia leaf were investigated by using plasmid relation, comet, and Allium cepa assay. In the presence of  ∙OH radicals, the DNA in supercoil was start nicked into open circular form, which is the product of the single-stranded cleavage of supercoil DNA and quantified as fragmented separate bands on agarose gel in plasmid relation assay. In the plasmid relation and comet assay, the P. longifolia leaf extract exhibited strong inhibitory effects against H2O2-mediated DNA damage. A dose-dependent increase of chromosome aberrations was also observed in the Allium cepa assay. The abnormalities scored were stickiness, c-mitosis, bridges, and vagrant chromosomes. Micronucleated cells were also observed at the interphase. The results of Allium cepa assay confirmed that the methanol extracts of P. longifolia exerted no significant genotoxic or mitodepressive effects at 100 μg/mL. Thus, this study demonstrated that P. longifolia leaf extract has a beneficial effect against oxidative DNA damage. This experiment is the first report for the protective effect of P. longifolia on DNA damage-induced by hydroxyl radicals. Additionally in acute oral toxicity study, female rats were treated at 5000 mg/kg body weight of P. longifolia leaf extract and observed for signs of toxicity for 14 days. P. longifolia leaf extract did not produce any treatment-related toxic effects in rats.

    3-monochloro-1, 2-propanediol fatty acid esters (3-MCPDEs) comprise a group of food toxicants formed during food processing. 3-MCPDEs have received increasing attention concerning their potential negative effects on human health. However, reports on the toxicity of 3-MCPD esters are still limited. To determine the effects of fatty acid substitutions on the toxicity of their esters, 1-stearic, 1-oleic, 1-linoleic, 1-linoleic-2-palmitic and 1-palmitic-2-linoleic acid esters of 3-MCPD were synthesized and evaluated with respect to their acute oral toxicities in Swiss mice. 3-MCPDEs were obtained through the reaction of 3-MCPD and fatty acid chlorides, and their purities and structures were characterized by ultraperformance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-Q-TOF-MS), infrared, 1 H and 13 C spectroscopic analyses. Medial lethal doses of 1-stearic, 1-oleic, 1-linoleic, 1-linoleic-2-palmitic and 1-palmitic-2-linoleic acid esters were 2973.8, 2081.4, 2016.3, 5000 and > 5000 mg kg -1 body weight. For the first time, 3-MCPDEs were observed for their toxic effects in the thymus and lung. In addition, major histopathological changes, as well as blood urea nitrogen and creatinine, were examined for mice fed the five 3-MCPDEs. The results from the present study suggest that the degree of unsaturation, chain length, number of substitution and relative substitution locations of fatty acids might alter the toxicity of 3-MCPDEs. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Patients with schizoaffective disorder (SCA) experience complicated interplays of psychotic, depressive, and manic symptoms. Paliperidone extended-release (pali ER) tablets have been shown to be efficacious in these patients, but treatment response has not been studied relative to the onset of effects for these symptom domains. In a pooled analysis of data from two 6-week, randomized, placebo-controlled studies, the onset of treatment effects with oral pali ER was evaluated by symptom domain (psychosis, depression, mania) in patients with an acute SCA exacerbation. Subjects were categorized as having prominent psychotic (Positive and Negative Syndrome Scale score >70), depressive (Hamilton Rating Scale for Depression-21 score ≥16), or manic (Young Mania Rating Scale score ≥16) symptoms at baseline. Of the 614 patients in these analyses, 597 (97.2%), 411 (66.9%), and 488 (79.5%) had prominent psychotic, depressive, and manic symptoms at baseline, respectively. Pali ER treatment was associated with rapid and significant improvement of all three symptom domains versus placebo within 1 week of initiation, regardless of whether treatment was given as monotherapy or in combination with mood stabilizers and/or antidepressants. Adverse events were similar to those reported in the original published studies. This post hoc analysis of two phase 3 trials requires confirmation in prospective studies. This pooled analysis suggests that treatment with pali ER is associated with rapid control of psychotic, depressive, and manic symptoms in patients with SCA. Its findings support the benefit of pali ER as a primary treatment for the management of SCA. Copyright © 2015 The Authors. Published by Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Previous studies have documented the increased cardiovascular risk associated with the use of some nonsteroidal anti-inflammatory drugs (NSAIDs. Despite this, many old NSAIDs are still prescribed worldwide. Most of the studies to date have been focused on specific oral drugs or limited by the number of cases examined. We studied the risk of new acute myocardial infarction (AMI hospitalization with current use of a variety of oral and parenteral NSAIDs in a nationwide population, and compared our results with existing evidence. Methods We conducted a case-crossover study using the Taiwan's National Health Insurance claim database, identifying patients with new AMI hospitalized in 2006. The 1-30 days and 91-120 days prior to the admission were defined as case and matched control period for each patient, respectively. Uses of NSAIDs during the respective periods were compared using conditional logistic regression and adjusted for use of co-medications. Results 8354 new AMI hospitalization patients fulfilled the study criteria. 14 oral and 3 parenteral NSAIDs were selected based on drug utilization profile among 13.7 million NSAID users. The adjusted odds ratio, aOR (95% confidence interval, for risk of AMI and use of oral and parenteral non-selective NSAIDs were 1.42 (1.29, 1.56 and 3.35 (2.50, 4.47, respectively, and significantly greater for parenteral than oral drugs (p for interaction Conclusions The collective evidence revealed the tendency of increased AMI risk with current use of some NSAIDs. A higher AMI risk associated with use of parenteral NSAIDs was observed in the present study. Ketorolac had the highest associated risk in both oral and parenteral NSAIDs studied. Though further investigation to confirm the association is warranted, prescribing physicians and the general public should be cautious about the potential risk of AMI when using NSAIDs.

    Zoledronic acid-induced uveitis (ZAIU) is rare but severe, and has been recently considered part of an acute phase reaction. Only 15 cases have been reported since 2005. Here we describe a case with macular edema, which is the first reported case observed after long-term alendronate tolerance. A 63-year-old Asian woman received her first intravenous zoledronic acid treatment for the management of postmenopausal osteoporosis as a more convenient substitute for oral alendronate. Twenty-four hours later, bilateral eye irritations, periorbital swelling, blurred vision, and diplopia presented. The complete blood count and transaminase levels were normal, but the erythrocytic sedimentation, C-reactive protein, and serum C4 levels were elevated. On detailed ophthalmological examination, a diagnosis of bilateral acute uveitis and macular edema in the right eye was made. The ocular symptoms were not improved until administration of topical and oral steroids. Complete resolution was achieved. There was no rechallenge of bisphosphonates, and no recurrence at 6 months follow-up. Based on an extensive review, abnormal fundus is rarely reported, especially in cases of macular edema. Rechallenge with zoledronic acid in five cases induced no additional uveitis, and changing the medication to pamidronate in another patient was also tolerated. Interestingly, our patient suffered from uveitis soon after intravenous zoledronate exposure after a two-year tolerance to oral alendronate. This is the first report of zoledronic acid induced uveitis with macular edema after long-term alendronate tolerance. Prior oral alendronate may not entirely prevent ZAIU. Steroids are usually necessary in the treatment of ZAIU. Bisphosphonate rechallenge is not fully contraindicated, and prior steroid administration may be a more reasonable treatment choice according to the available evidence.

    2015-09-01

    To summarize recent data on classification systems, cause, risk factors, severity prediction, nutrition, and drug treatment of acute pancreatitis. Comparison of the Revised Atlanta Classification and Determinant Based Classification has shown heterogeneous results. Simvastatin has a protective effect against acute pancreatitis. Young black male, alcohol, smoldering symptoms, and subsequent diagnosis of chronic pancreatitis are risk factors associated with readmissions after acute pancreatitis. A reliable clinical or laboratory marker or a scoring system to predict severity is lacking. The PYTHON trial has shown that oral feeding with on demand nasoenteric tube feeding after 72 h is as good as nasoenteric tube feeding within 24 h in preventing infections in predicted severe acute pancreatitis. Male sex, multiple organ failure, extent of pancreatic necrosis, and heterogeneous collection are factors associated with failure of percutaneous drainage of pancreatic collections. The newly proposed classification systems of acute pancreatitis need to be evaluated more critically. New biomarkers are needed for severity prediction. Further well designed studies are required to assess the type of enteral nutritional formulations for acute pancreatitis. The optimal minimally invasive method or combination to debride the necrotic collections is evolving. There is a great need for a drug to treat the disease early on to prevent morbidity and mortality.

    1997-04-26

    The association between oral contraceptive (OC) use and acute myocardial infarction (AMI) was established in studies from northern Europe and the USA, which took place during the 1960s and 1970s. Few data are available to quantify the risk worldwide of AMI associated with use of OCs introduced since those early studies. This hospital-based case-control study examined the association between a first AMI and current OC use in women from Africa, Asia, Europe, and Latin America (21 centres). Cases were women aged 20-44 years who had definite or possible AMI (classified by history, electrocardiographic, and cardiac-enzyme criteria), who were admitted to hospital, and who survived for at least 24 h. Up to three hospital controls matched by 5-year age-band were recruited for each of the 368 cases (941 controls). All participants were interviewed while in hospital with the same questionnaire, which included information on medical and personal history, lifetime contraceptive use, and blood-pressure screening before the most recent episode of OC use. Odds ratios compared the risk of AMI in current OC users and in non-users (past users and never-users combined). The overall odds ratio for AMI was 5.01 (95% CI 2.54-9.90) in Europe and 4.78 (2.52-9.07) in the non-European (developing) countries; however, these risk estimates reflect the frequent coexistence of other risk factors among OC users who have AMI. Very few AMIs were identified among women who had no cardiovascular risk factors and who reported that their blood pressure had been checked before OC use; odds ratios associated with OC use in such women were not increased in either Europe or the developing countries. Among OC users who smoked ten or more cigarettes per day, the odds ratios in Europe and in the developing countries were over 20. Similarly, among OC users with a history of hypertension (during pregnancy or at any other time), odds ratios were at least ten in both groups of countries. No consistent

    Full Text Available La Solución CM-95 tratada magnéticamente es un producto en desarrollo que mostró propiedades inmunoestimulantes en ensayos preclínicos, característica que la hacen adecuada como candidata a inmunopotenciador. En este trabajo se evaluaron los posibles efectos tóxicos preclínicos de la Solución CM-95 tratada magnéticamente, por el método de las Clases de Toxicidad Aguda y el de irritación de la mucosa oral, adaptando las normas OECD 423 y la ISO 10993-10, respectivamente. En el método de las Clases de Toxicidad Aguda se utilizó el ensayo límite, en ratas Sprague Dawley hembras, en el cual la dosis estuvo relacionada con el nivel de inducción magnética, en este caso 0,16 T, aplicado a la Solución CM-95; y el volumen a administrar de la misma, calculado sobre la base de 2 ml de la solución por 100 g de peso corporal. La determinación de la irritación de la mucosa oral se llevó a cabo en hámster Sirios Dorados hembras mediante un ensayo a dosis repetidas durante 7 días de tratamiento en la bolsa gular derecha, con pellet de algodón impregnado con 0,5 ml de la solución tratada magnéticamente con la misma inducción. No se encontró mortalidad ni evidencias de signos tóxicos para el ensayo de toxicidad aguda, y se obtuvo un índice de irritación sobre mucosa oral de 0, por lo que la sustancia estudiada se enmarcó como "No clasificada" y "No irritante" según la metodología empleada. Estos resultados complementarán otros estudios toxicológicos para avalar la seguridad de esta Solución para su uso futuro como fármaco por vía oral.CM-95 solution magnetically treated is a product which showed immunologic properties in preliminary tests, characteristic that makes it adequate as inmunopotentiator candidate.

    Full Text Available Tetrodotoxin (TTX is starting to appear in molluscs from the European waters and is a hazard to seafood consumers. This toxin blocks sodium channels resulting in neuromuscular paralysis and even death. As a part of the risk assessment process leading to a safe seafood level for TTX, oral toxicity data are required. In this study, a 4-level Up and Down Procedure was designed in order to determine for the first time the oral lethal dose 50 (LD50 and the No Observed Adverse Effect Level (NOAEL in mice by using an accurate well-characterized TTX standard.

    2015-01-01

    The safety of rare sugar syrup obtained from high-fructose corn syrup under slightly alkaline conditions was studied. Mutagenicity of rare sugar syrup was assessed by a reverse mutation assay using Salmonella typhimurium and Escherichia coli, and an in vitro chromosomal aberration assay using Chinese hamster lung cell line (CHL/IU). No mutagenicity of rare sugar syrup was detected under these experimental conditions. Oral administration of single dose (15,000 mg/kg) of rare sugar syrup to rats caused no abnormalities, suggesting no adverse effect of rare sugar syrup. In humans, the acute non-effect level of rare sugar syrup for causing diarrhea was estimated as 0.9 g/kg body weight as dry solid base in both males and females.

    Multimodal analgesia constitutes a common strategy in pain management. A tramadol hydrochloride 75 mg/dexketoprofen 25 mg oral fixed combination (TRAM/DKP 75 mg/25 mg) has been recently registered and released in Europe for the treatment of moderate-to-severe acute pain. This paper provides additional analyses on the results of two phase III clinical trials (DEX-TRA-04 and DEX-TRA-05) on postoperative pain to document its sustained effect. The analysis was applied to a modified intention-to-treat population (mITT, n = 933) of patients undergoing active treatment from the first dose, to assess the sustained effect of TRAM/DKP 75 mg/25 mg on pain intensity (PI-VAS 0-100) over 56 h from first drug intake. The superior analgesic effect of TRAM/DKP 75 mg/25 mg over 56 h in terms of difference in PI-VAS (mean [SE]) was shown for DEX-TRA-04 (-11.0 [0.55] over dexketoprofen 25 mg and -9.1 [0.55] over tramadol 100 mg, P ≤ 0.0001) and for DEX-TRA-05 (-10.4 [0.51] over dexketoprofen 25 mg and -8.3 [0.51] over tramadol 100 mg, P ≤ 0.0001). The statistical analysis performed on data coming from both studies confirms the superior sustained analgesia of TRAM/DKP 75 mg/25 mg over tramadol 100 mg and dexketoprofen 25 mg. These results are consistent with the previously published data obtained on the ITT population and strongly support the role of this oral fixed-dose combination in the treatment of moderate-to-severe acute pain.

    A randomized pilot study to compare the safety and efficacy of artesunate suppositories (15 mg/kg/day for three days) versus oral artesunate (6 mg/kg/day for three days), both in combination with mefloquine (25 mg/kg), was conducted in 52 Thai children with uncomplicated multidrug-resistant falciparum malaria. Forty-five patients (87%) had a full 28-day follow-up in the hospital to assess efficacy and exclude reinfection. Mean [range] times to fever clearance of the two groups were similar (42 hr [15-104] versus 42 hr [6-119]). Artesunate suppositories resulted in significantly longer times to achieve 50% and 90% reductions of the initial parasite counts (17 and 26 hr versus 9 and 15 hr; P suppositories group (42 hr [14-93] versus 35 hr [16-69]), but the difference was not significant. The cure rates by days 28 were not significantly different, 92% for artesunate suppository-treated patients and 100% for oral artesunate-treated patients. Both drug regimens are safe and effective. Further studies are needed to characterize the pharmacokinetic properties and the optimum regimen of artesunate suppositories for the treatment of severe malaria.

    Delayed wound healing is a significant clinical problem in patients who have had previous irradiation. This study investigated the effectiveness of Aloe vera (Av) on acute radiation-delayed wound healing. The effect of Av was studied in radiation-exposed rats compared with radiation-only and control rats. Skin wounds were excised on the back of rats after 3 days of local radiation. Wound size was measured on days 0, 3, 6, 9, and 12 after wounding. Wound tissues were examined histologically and the expressions of transforming growth factor β-1 (TGF-β-1) and basic fibroblast growth factor (bFGF) were examined by immunohistochemistry and reverse-transcription polymerase chain reaction. Wound contraction was accelerated significantly by Av on days 6 and 12 after wounding. Furthermore, the inflammatory cell infiltration, fibroblast proliferation, collagen deposition, angiogenesis, and the expression levels of TGF-β-1 and bFGF were significantly higher in the radiation plus Av group compared with the radiation-only group. These data showed the potential application of Av to improve the acute radiation-delayed wound healing by increasing TGF-β-1 and bFGF production. Copyright © 2011 Elsevier Inc. All rights reserved.

    Background Results from the Diuretic Optimization Strategies in Acute Heart Failure (DOSE-AHF) study suggest that an initial continuous infusion of loop diuretics is not superior to bolus dosing with regard to clinical endpoints in AHF. We hypothesized that outpatient furosemide dose was associated with congestion and poorer renal function, and explored the hypothesis that a continuous infusion may be more effective in patients on higher outpatient diuretic doses. Methods DOSE-AHF randomized 308 patients within 24 hours of admission to high vs. low initial intravenous diuretic dose given as either a continuous infusion or bolus. We compared baseline characteristics and assessed associations between mode of administration (bolus vs. continuous) and outcomes in patients receiving high-dose (≥120 mg furosemide equivalent, n=177) versus low-dose (diuretics. Results Patients on higher doses of furosemide were less frequently on renin-angiotensin system inhibitors (P=.01), and had worse renal function and more advanced symptoms. There was a significant interaction between outpatient dose and mode of therapy (P=0.01) with respect to net fluid loss at 72 hours after adjusting for creatinine and intensification strategy. Admission diuretic dose was associated with an increased risk of death or rehospitalization at 60 days (adjusted HR=1.08 per 20-mg increment in dose, 95% CI 1.01–1.16, P=.03). Conclusions In acute HF, patients on higher diuretic doses have greater disease severity, and may benefit from an initial bolus strategy. PMID:23194486

    Renal impairment and fluctuations in renal function are common in patients recently hospitalized for acute heart failure and in those with atrial fibrillation. The aim of the present study was to evaluate the hypothetical need for dosage adjustment (based on fluctuations in kidney function) of dabigatran, rivaroxaban and apixaban during the first 6 months after hospital discharge in patients with concomitant atrial fibrillation and heart failure. An observational study was conducted in 162 patients with nonvalvular atrial fibrillation after hospitalization for acute decompensated heart failure who underwent creatinine determinations during follow-up. The hypothetical recommended dosage of dabigatran, rivaroxaban and apixaban according to renal function was determined at discharge. Variations in serum creatinine and creatinine clearance and consequent changes in the recommended dosage of these drugs were identified during 6 months of follow-up. Among the overall study population, 44% of patients would have needed dabigatran dosage adjustment during follow-up, 35% would have needed rivaroxaban adjustment, and 29% would have needed apixaban dosage adjustment. A higher proportion of patients with creatinine clearance renal impairment. Further studies are needed to clarify the clinical importance of these needs for drug dosing adjustment and the ideal renal function monitoring regime in heart failure and other subgroups of patients with atrial fibrillation.

    2007-04-01

    Full Text Available Introduction: Certain painful, invasive procedures are necessary for care, and are commonly performed in both healthly and sick neonates. Current evidence shows that the newborn infant has both physiologic and anatomic capacity to experience pain. Recent research suggests that pain experienced in the neonatal period might have long-term effects later in life. Previous research has shown that orally administered sweet-tasting solutions reduce signs of pain during painful procedures. This effect is considered to be mediated both by the release of endorphins and by a preabsorptive mechanism related to the sweet taste. Methods: This study was a controlled , randomized and double – blind study on 210 neonates. These newborns were randomly divided into 3 groups; A, B and C. Group A received 2 ml of 25% sucrose orally as well as base cream was applied at the site for heel stick, group B received 2 ml of distilled water and application of EMLA cream, while group C received 2 ml of distilled water and base cream. The heart rates of the newborn were recorded by the cardiac monitor before and after heel stick blood sampling and the duration of crying was determined as well. Pain was scored by DAN scale.There were no differences in demographic characteristics of all neonates. Results: The results showed that the DAN scale was significantly lower in the sucrose group (mean : 3.840 as compared to the EMLA group (mean: 3.366 and the placebo group(5.557, but the difference in the duration of crying was not significantly different in the sucrose group (mean: 10.5 second and the EMLA group(mean 8.76. Conclusion: Both sucrose and EMLA are effective in reducing stress associated with heel lancet in newborns, but as sucrose acts faster and is healthier, its usage is proposed in neonates requiring heel sticks for blood sampling.

    Our goal is to assess if current antiplatelet (AP) use has an effect on recanalization rate and outcome in acute stroke patients. We conducted a retrospective analysis of acute stroke patients who received intravenous (IV) recombinant tissue plasminogen activator (rt-PA) and had transcranial Doppler examination within 3 h of symptom onset. The TCD findings were interpreted using the Thrombolysis in Brain Ischemia flow grading system as persistent arterial occlusion, reocclusion or complete recanalization. Complete recanalization was defined as established Thrombolysis in Brain Ischemia 4 or 5 within 2 h of IV rt-PA. The patients were divided based on their current use of AP agents. Comparisons were made between the different groups based on recanalziation rate, reocclusion and good long-term outcome (mRS ≤ 2) using χ(2) test. Multiple regression analysis was used to identify AP use as a predictor for recanalization and outcome including symptomatic intracranial hemorrhage after controlling for age, baseline NIHSS score, time to treatment, previous vascular event, hypertension and diabetes mellitus. Two hundred and eighty-four patients were included; 154 (54%) males, 130 (46%) females, with a mean age of 69.5 ± 13 years. The median baseline NIHSS score was 16 ± 5. The median time to TCD examination was 131 ± 38 min from symptom onset. The median time to IV rt-PA was 140 ± 34 min. One hundred eighty patients were not on AP prior to their stroke, 76 were on aspirin, 15 were on clopidogrel, 2 were on aspirin-dipyridamole combination, 2 were on both aspirin and clopidogrel, and 9 patients on subtherapeutic coumadin. In patients who were naïve to AP, 68/178 (38.2%) had complete recanalization, whereas in the AP group, 25/91 (28%) had complete recanalization. Patients on aspirin alone had a lower recanalization rate (16/72) as compared to those not on AP (22 vs. 39%) (p = 0.017), while those on clopidogrel had higher rates of complete recanalization (9/19, 60

    Vitamin K antagonists were the only choice for chronic oral anticoagulation for more than half a century. Over the past few years, direct oral anticoagulants have emerged, including one direct thrombin inhibitor (dabigatran etexilate) and three factor Xa inhibitors (apixaban, edoxaban and rivaroxaban). In randomised controlled trials comparing direct oral anticoagulants with traditional vitamin K antagonists, the direct oral anticoagulants all showed a favourable benefit-risk balance in their safety and efficacy profile, in prevention of thromboembolic events in patients with atrial fibrillation and in the prevention and treatment of venous thromboembolism and acute coronary syndrome. In 2008, dabigatran was the first direct oral anticoagulant approved by the European Medicine Agency. Subsequently, rivaroxaban, apixaban and edoxaban were also authorised. This article reviews the evidence related to the use of these drugs. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    2010-01-01

    Candidiasis, an often encountered oral disease, has been increasing in frequency. Most commonly caused by the overgrowth of Candida albicans, oral candidiasis can be divided into several categories including acute and chronic forms, and angular cheilitis. Risk factors for the development of oral candidiasis include immunosuppression, wearing of dentures, pharmacotherapeutics, smoking, infancy and old age, endocrine dysfunction, and decreased salivation. Oral candidiasis may be asymptomatic. More frequently, however, it is physically uncomfortable, and the patient may complain of burning mouth, dysgeusia, dysphagia, anorexia, and weight loss, leading to nutritional deficiency and impaired quality of life. A plethora of antifungal treatments are available. The overall prognosis of oral candidiasis is good, and rarely is the condition life threatening with invasive or recalcitrant disease.

    Co-crystal of tramadol-celecoxib (CTC), containing equimolar quantities of the active pharmaceutical ingredients (APIs) tramadol and celecoxib (100 mg CTC = 44 mg rac-tramadol hydrochloride and 56 mg celecoxib), is a novel API-API co-crystal for the treatment of pain. We aimed to establish the effective dose of CTC for treating acute pain following oral surgery. A dose-finding, double-blind, randomised, placebo- and active-controlled, multicentre (nine Spanish hospitals), phase II study (EudraCT number: 2011-002778-21) was performed in male and female patients aged ≥ 18 years experiencing moderate to severe pain following extraction of two or more impacted third molars requiring bone removal. Eligible patients were randomised via a computer-generated list to receive one of six single-dose treatments (CTC 50, 100, 150, 200 mg; tramadol 100 mg; and placebo). The primary efficacy endpoint was the sum of pain intensity difference (SPID) over 8 h assessed in the per-protocol population. Between 10 February 2012 and 13 February 2013, 334 patients were randomised and received study treatment: 50 mg (n = 55), 100 mg (n = 53), 150 mg (n = 57), or 200 mg (n = 57) of CTC, 100 mg tramadol (n = 58), or placebo (n = 54). CTC 100, 150, and 200 mg showed significantly higher efficacy compared with placebo and/or tramadol in all measures: SPID (0-8 h) (mean [standard deviation]): - 90 (234), - 139 (227), - 173 (224), 71 (213), and 22 (228), respectively. The proportion of patients experiencing treatment-emergent adverse events was lower in the 50 (12.7% [n = 7]), 100 (11.3% [n = 6]), and 150 (15.8% [n = 9]) mg CTC groups, and similar in the 200 mg (29.8% [n = 17]) CTC group, compared with the tramadol group (29.3% [n = 17]), with nausea, dizziness, and vomiting the most frequent events. Significant improvement in the benefit-risk ratio was observed for CTC (doses ≥ 100 mg) over tramadol and placebo in

    The Condalia buxifolia root bark infusion is used in traditional medicine in Brazil as antipyretic, anti-inflammatory and anti-dysentery. Previous data from our group showed that methanolic extract of Condalia buxifolia (MECb) produced a marked antinociceptive effect in animal models of acute pain. The purpose of this study was to investigate the mechanisms of MECb-induced antinociception as measured by nocifensive behavior in pain induced by endogenous (prostaglandin E2) or exogenous (TRPs and ASIC agonist, and protein kinase A and C activators) chemical stimuli, and the potential role of PKA signaling and capsaicin-sensitive central C-fiber afferents. The effect of MECb administered orally (0.1-300mg/kg, i.g.) to mice on nociception induced by capsaicin (TRPV1 agonist), cinnamaldehyde (TRPA1 agonist), menthol (TRPM8 agonist), acidified saline (ASIC agonist), PMA (protein kinase C activator), PGE2 and forskolin (protein kinase A activator) was assessed. Moreover, this study also investigated the role of C-fibers desensitizing mice with a high dose of intrathecal capsaicin. Furthermore, this study performed the western blot to PKA phosphorylated on nocifensive behavior induced by forskolin. MECb was able to reduce the nociception and paw edema induced by capsaicin, acidified saline, PMA, PGE2 and forskolin, but not by cinnamaldehyde or menthol. Western blot analyses showed that MECb reduced the levels of PKA phosphorylation induced by forskolin in hind paws. Finally, ablating central afferent C-fibers abolished MECb antinociception. In accordance with its use in traditional medicine, these findings provide new evidence indicating that Condalia buxifolia reduces the acute painful behavior of animals caused by chemical stimuli. The precise mechanism of MECb antinociceptive activity is not completely understood but the results suggest involvement of PGE2, TRPV1/ASIC and PKA signaling pathways, and require integrity of the capsaicin-sensitive central C-fiber afferents

    Leukemia is the most common neoplastic disease of the white blood cells which is important as a pediatric malignancy. Oral manifestations occur frequently in leukemic patients and may present as initial evidence of the disease or its relapse. The symptoms include gingival enlargement and bleeding, oral ulceration, petechia, mucosal pallor, noma, trismus and oral infections. Oral lesions arise in both acute and chronic forms of all types of leukemia. These oral manifestations either may be the result of direct infiltration of leukemic cells (primary) or secondary to underlying thrombocytopenia, neutropenia, or impaired granulocyte function. Despite the fact that leukemia has long been known to be associated with oral lesions, the available literature on this topic consists mostly of case reports, without data summarizing the main oral changes for each type of leukemia. Therefore, the present review aimed at describing oral manifestations of all leukemia types and their dental management. This might be useful in early diagnosis, improving patient outcomes.

  10. Fosfomycin trometamol: a review of its use as a single-dose oral treatment for patients with acute lower urinary tract infections and pregnant women with asymptomatic bacteriuria.

    Keating, Gillian M

    2013-11-01

    Fosfomycin trometamol (fosfomycin tromethamine) [Monuril(®), Monurol(®), Monural(®)] is approved in numerous countries worldwide, mainly for the treatment of uncomplicated urinary tract infections (UTIs). Fosfomycin has good in vitro activity against common uropathogens, such as Escherichia coli (including extended-spectrum β-lactamase-producing E. coli), Proteus mirabilis, Klebsiella pneumoniae and Staphylococcus saprophyticus, and the susceptibility of uropathogens to fosfomycin has remained relatively stable over time. A single oral dose of fosfomycin trometamol 3 g (the approved dosage) achieves high concentrations in urine. Results of recent randomized trials indicate that single-dose fosfomycin trometamol had similar clinical and/or bacteriological efficacy to 3- to 7-day regimens of ciprofloxacin, norfloxacin, cotrimoxazole or nitrofurantoin in women with uncomplicated lower UTIs. In addition, single-dose fosfomycin trometamol had similar bacteriological efficacy to a 5-day course of cefuroxime axetil or a 7-day course of amoxicillin/clavulanic acid in pregnant women with asymptomatic bacteriuria, and similar clinical and/or bacteriological efficacy to a 5-day course of cefuroxime axetil or amoxicillin/clavulanic acid or a 3-day course of ceftibuten in pregnant women with a lower UTI. Single-dose fosfomycin trometamol was generally well tolerated, with gastrointestinal adverse events (e.g. diarrhoea, nausea) reported most commonly. In conclusion, single-dose fosfomycin trometamol is an important option for the first-line empirical treatment of uncomplicated lower UTIs.

    Vulvovaginal candidiasis is the second most common cause of vaginal infections following bacterial vaginosis. For the treatment of vulvovaginal candidiasis, antifungal agents are used either as topical (vaginal tablets and cream) or oral formulations. A single oral 150 mg dose of fluconazole has been recommended as the standard therapy for uncomplicated, acute vulvovaginal candidiasis in global guidelines; however, in Japan oral fluconazole therapy has not been approved. We conducted a phase 3 study to evaluate the efficacy and safety of a single oral 150 mg dose of fluconazole in Japanese subjects with vulvovaginal candidiasis for regulatory submission. A total of 157 subjects received a single oral 150 mg dose of fluconazole. Candida species (104 strains) were identified by fungal culture from 102 subjects at baseline, including Candida albicans (100 strains). The efficacy rate for the therapeutic outcome (assessed based on a comprehensive evaluation of the clinical and mycological efficacy in each subject) was 74.7% (74/99) on Day 28 in the modified Intent-To-Treat (m-ITT) population. Concerning the clinical and mycological efficacy on Day 28 in the m-ITT population, the cure, cure or improvement, and eradication rates were 81.6%, 95.9%, and 85.9%, respectively. The most common treatment-related adverse events were diarrhea and nausea (1.9% for each). No clinically significant safety issues were reported. A single oral 150 mg dose of fluconazole demonstrated excellent therapeutic efficacy and was well tolerated in Japanese subjects with vulvovaginal candidiasis. NCT01806623.

    This paper explores the relationship between a new assertiveness measure (the Scale for Interpersonal Behaviour--SIB), social comparison and submissive behaviour. The paper investigates these measures in relation to the personality traits of neuroticism and introversion. Findings suggest: (a) that social comparison may be an important variable in assertiveness and submissive behaviour and shows a strong relationship to neuroticism and introversion; (b) that submissive behaviour is not the mirror opposite of assertive behaviour; and (c) submissive behaviour seems more strongly associated with introversion and neuroticism than assertive performance.

    Guan-Xin-Shu-Tong capsules are one of the well-known and first-line Chinese traditional herbal formula for treating coronary heart disease. A validated and sensitive method via ultra fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS) was established to simultaneously determinate five phenolic acids and four diterpenoids in rats in order to investigate their pharmacokinetic profiles firstly. Analytes were extracted by ethyl acetate and determined via multiple reaction monitoring mode in both positive and negative ion modes. The values for limit of quantification were in range of 0.025-1.250ng/ml. Inter- and intra-day precisions were no more than 10.9% with accuracy of -11.0%-10.6%, meanwhile the stable and suitable extraction recoveries were also obtained. And finally such excellent method was used to compare the pharmacokinetics of nine compounds in normal and acute blood stasis rats after oral administration of Guan-Xin-Shu-Tong capsules.

    The genus Hyptis comprehends almost 400 species widespread in tropical and temperate regions of America. The use of Hyptis spicigera Lam. (Lamiaceae) is reported in traditional medicine due to its gastroprotective, anti-inflammatory and analgesic properties. The rationale of this study was to investigate the potential use of the essential oil of H. spicigera (EOHs) as analgesic. The antinociceptive effect of EOHs was verified analyzing acute nocifensive behavior of mice induced by chemical noxious stimuli [i.e., formalin and transient receptor potential (TRP) channels agonists]. We also verified the effects of EOHs on locomotor activity and motor performance in mice. Finally, we investigate the involvement of central afferent C-fibers with EOHs analgesic effect. EOHs presented antinociceptive effect at 300 and 1000mg/kg on formalin-induced pain behavior model, presenting 50% and 72% of inhibition during the first phase (ED 50 =292mg/kg), and 85% and 100% during de second phase (ED 50 =205mg/kg), respectively. Temperature of the hind paw was reduced by EOHs treatment in a dose-dependent manner; oedema was diminished only by EOHs 1000mg/kg. EOHs does not impaired locomotor activity or motor performance. For mice injected with capsaicin, a TRPV1 activator, EOHs (1000mg/kg, ED 50 =660mg/kg) showed decreased (63%) nociceptive behavior. When injected with cinnamaldehyde (TRPA1 activator), mice treated with EOHs showed 23%, 43% and 66% inhibition on nociceptive behavior (100, 300 and 1000mg/kg, respectively; ED 50 402mg/kg). When mice were injected with menthol (TRPM8 activator), EOHs showed 29%, 59% and 98% inhibition of nociceptive behavior (100, 300 and 1000mg/kg, respectively; with ED 50 =198mg/kg. Finally, when desensitized mice were injected with menthol, EOHs (300mg/kg) does not show antinociceptive effect. This study demonstrated the efficacy of EOHs on experimental models of nociception. We have found the involvement of TRP channels V1, A1 and M8 with EOHs

    2016-02-01

    Lichen planus (LP) is a relatively common autoimmune T-cell-mediated disease of unknown aetiology affecting the mucous membranes, skin and nails. Its prevalence varies between 0.5 and 2.2% of the population in epidemiological studies with a peak incidence in the 30-60 years range and with a female predominance of 2:1. Mucosal lichen planus tends to follow a chronic course with acute exacerbations. Spontaneous remission of oral lichen planus (OLP) is uncommon, and indeed mucosal LP may become worse with time. In contrast, cutaneous lichen planus may follow a milder clinical course though some variants may be severe such as those affecting the palms and soles and the scalp and the genital tract in females (vulvovaginal gingival LP) where scarring leads to significant complications. It is important to identify those cases that may be drug induced or be associated with a contact allergic or irritant reaction (lichenoid reaction) or the rarer oral presentation of discoid lupus erythematosus. There is a very small risk of malignancy (approximately 1:200 patients/year) associated with oral lichen planus; thus patients should be informed that long term monitoring via their general dental practitioner is appropriate. This review will focus on the clinical presentation and management of oral lichen planus.

    1990-01-01

    A number of acute oral complications may be associated with cancer therapy in children, but the extent and duration of these complications, and the most effective management techniques. have not been well described. The few studies differ in design, making comparisons difficult. Well-controlled, prospective clinical studies are needed to define the most effective strategies for the management of acute oral complications in children. However, it is clear that dental intervention prior to cancer therapy is an important factor in the optimal preparation of the patient. During cancer therapy, intensive supervised oral preventive protocols appear to be of benefit to the child's oral health, overall comfort, and well-being. Furthermore, the prevention of oral infection may significantly reduce the morbidity associated with cancer therapy. Long-term preventive oral care may help prevent dental disease and infection in medically compromised children and contribute to improving the quality of life. 41 references

    In the U.S. oral cancer accounts for 2.1% of all cancers and 1% of cancer deaths. Two to three times as many males as females are affected. Blacks have more intra-oral cancer than whites, and their incidence and mortality rates have increased in recent years. The etiologic process very likely involves several factors. The major etiologic agents are tobacco (all types) and alcoholic beverages. Herpes simplex virus, human papilloma virus, and Candida have been implicated. Host factors include poor state of dentition, nutritional aberrations, cirrhosis of liver, lichen planus, and immunologic impairmant. Cellular changes include amplification of some oncogenes, alterations in antigen expression, production of gamma-glutamyl transpeptidase, and disturbance of keratin and involucrin production. Experimentally, cancer is readily produced on the hamster cheek pouch and rat oral mucosa. Unlike oral cancer in humans, most experimental lesions are exophytic, and they rarely metastasize.

    Full Text Available Topiramato é droga derivada das sulfas e utilizada sistemicamente como anticonvulsivante. Pode produzir efusão uveal e causar glaucoma agudo por fechamento angular pelo deslocamento da íris e do cristalino anteriormente, com miopização transitória. O processo cede com a suspensão da droga, se identificado precocemente. Os autores relatam, pela primeira vez na literatura científica nacional, um caso no qual a efusão uveal ocorreu após a administração de topiramato para tratamento de enxaqueca. Paciente branca de 40 anos foi examinada no setor de emergência do Hospital Banco de Olhos de Porto Alegre apresentando cefaléia intensa, dor ocular e diminuição da visão em ambos os olhos. Referia uso de topiramato desde dez dias antes do início dos sintomas. O exame biomicroscópico mostrava injeção conjuntival, quemose e câmara anterior rasa nos dois olhos. A pressão intra-ocular era de 40 mmHg no olho direito e 38 mmHg no olho esquerdo. Os achados fundoscópicos estavam normais nos dois olhos. A ultra-sonografia ocular mostrou efusão uveal e descolamento de coróide bilateral nos dois olhos. Foi realizado o diagnóstico de efusão uveal relacionada com o uso de topiramato. A medicação foi suspensa com melhora do quadro clínico e da acuidade visual três dias após a apresentação inicial. A efusão uveal induzida por drogas ocorre raramente. O topiramato pode causar edema do corpo ciliar e relaxamento da zônula, com conseqüente deslocamento anterior do diafragma irido-cristaliniano, causando miopização aguda e fechamento angular. Como o mecanismo de fechamento angular não envolve bloqueio pupilar, iridectomias periféricas e o uso de mióticos tópicos não são efetivos nesses casos. Houve regressão completa do quadro após a suspensão da medicação.This paper reports a clinical case of uveal effusion in both eyes causing bilateral acute angle closure glaucoma in a young patient after oral administration of topiramate

    Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

    2016-03-01

    Poor oral health has been associated with systemic diseases, morbidity and mortality. Many patients in hospital environments are physically compromised and rely upon awareness and assistance from health professionals for the maintenance or improvement of their oral health. This study aimed to identify whether common individual and environment factors associated with hospitalisation impacted on oral hygiene. Data were collected during point prevalence audits of patients in the acute and rehabilitation environments on three separate occasions. Data included demographic information, plaque score, presence of dental hygiene products, independence level and whether nurse assistance was documented in the health record. Data were collected for 199 patients. A higher plaque score was associated with not having a toothbrush (p = 0.002), being male (p = 0.007), being acutely unwell (p = 0.025) and requiring nursing assistance for oral hygiene (p = 0.002). There was fair agreement between the documentation of requiring assistance for oral care and the patient independently able to perform oral hygiene (ICC = 0.22). Oral hygiene was impacted by factors arising from hospitalisation, for those without a toothbrush and male patients of acute wards. Establishment of practices that increase awareness and promote good oral health should be prioritised. © 2015 Nordic College of Caring Science.

    Wind turbines used to generate electricity can have important visual, environmental and amenity impacts depending on their location. Planning can contribute to the provision of renewable energy by enabling wind energy development in appropriate locations in a manner that appropriately balances their environmental, social and economic benefits with any demonstrated visual, environmental and amenity impacts. The County of Bruce, Ontario and member municipalities are attempting to balance these matters in favour of an overall net community benefit. Planning applications need to include sufficient information and explanation to allow the approval authorities to come to a sound and timely decision, in order to facilitate a viable wind energy industry. This document outlined the County of Bruce application requirements in order to assist in the design and siting of proposed wind energy facilities and in preparing planning applications. The County of Bruce official plan and policies for large wind energy conversion systems (LWECS) were presented. Submissions requirements include an environmental screening report; a federal environmental assessment clearance; a prime agricultural land justification report; a general project description; turbine specifications; noise evaluation; shadow flicker calculations; visual effect modelling; NAV Canada/Transport Canada clearance; grid connections and routing; project staging; overshadowing study; electromagnetic interference study; turbine foundation drawings; and an environmental management plan.

    Full Text Available Ronald C Hamdy,1,2 Dane N Daley11Osteoporosis Center, College of Medicine, East Tennessee State University, 2Veterans Affairs Medical Center, Johnson City, TN, USAAbstract: Calcitonin is a hormone secreted by the C-cells of the thyroid gland in response to elevations of the plasma calcium level. It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

  6. Oral care.

    Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. Copyright © 2011 S. Karger AG, Basel.

    2014-06-01

    This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute

    2008-11-01

    Internet-based sexuality research with hidden populations has become increasingly popular. Respondent anonymity may encourage participation and lower social desirability, but associated disinhibition may promote multiple submissions, especially when incentives are offered. The goal of this study was to identify the usefulness of different variables for detecting multiple submissions from repeat responders and to explore incentive effects. The data included 1,900 submissions from a three-session Internet intervention with a pretest and three post-test questionnaires. Participants were men who have sex with men and incentives were offered to rural participants for completing each questionnaire. The final number of submissions included 1,273 "unique", 132 first submissions by "repeat responders" and 495 additional submissions by the "repeat responders" (N = 1,900). Four categories of repeat responders were identified: "infrequent" (2-5 submissions), "persistent" (6-10 submissions), "very persistent" (11-30 submissions), and "hackers" (more than 30 submissions). Internet Provider (IP) addresses, user names, and passwords were the most useful for identifying "infrequent" repeat responders. "Hackers" often varied their IP address and identifying information to prevent easy identification, but investigating the data for small variations in IP, using reverse telephone look up, and patterns across usernames and passwords were helpful. Incentives appeared to play a role in stimulating multiple submissions, especially from the more sophisticated "hackers". Finally, the web is ever evolving and it will be necessary to have good programmers and staff who evolve as fast as "hackers".

    Sunburn, immune suppression, photo-aging, and skin cancers result from uncontrolled overexposure of human skin to solar ultraviolet radiation (UVR). Preventive measures, including photo-protection, are helpful and can be achieved by topical sun-screening agents. Polypodium leucotomos (PL) has been used for the treatment of inflammatory diseases and has shown some in vitro and in vivo immunomodulating properties. Its beneficial photo-protective effects in the treatment of vitiligo and its antioxidant properties encouraged us to evaluate in vivo the potentially useful photo-protective property of natural extract of PL after topical application or oral ingestion. Twenty-one healthy volunteers [either untreated or treated with oral psoralens (8-MOP or 5-MOP)] were enrolled in this study and exposed to solar radiation for evaluation of the following clinical parameters: immediate pigment darkening (IPD), minimal erythema dose (MED), minimal melanogenic dose (MMD), and minimal phototoxic dose (MPD) before and after topical or oral administration of PL. Immunohistochemical assessment of CD1a-expressing epidermal cells were also performed. PL was found to be photo-protective after topical application as well as oral administration. PL increased UV dose required for IPD (P<0.01), MED (P<0.001) and MPD (P<0.001). After oral administration of PL, MED increased 2.,8{+-}0.59 times and MPD increased 2.75{+-}0.5 and 6.8{+-}1.3 times depending upon the type of psoralen used. Immunohistochemical study revealed photo-protection of Langherhans cells by oral as well as topical PL. The observed photo-protective activities of oral or topical PL reveal a new avenue in examining the potentially useful field of systemic photo-protection and suggests that PL can be used as adjunct treatment and can make photochemotherapy and phototherapy possibly safe and effective when the control of cutaneous phototoxicity to PUVA or UVB is a limiting factor in such photo-therapies.

    to Houellebecq’s book as contesting the political thought-practices mapping the ideological landscape in contemporary Europe from below. It pays special attention to the ambiguity in Houellebecq’s criticism of Islamism and nationalism, his portrayal of the hypocrisy of liberal democrats and his misanthropy...... as regards the role of democratic citizens in future politics. The article also questions whether the satirical point of view that Houellebecq adopts constitutes an adequate point of departure for invigorating democratic imaginations. The argument is that the kind of negative ideological diagnosis...

    In the majority of surgical departments in Denmark, the postoperative treatment for acute perforated appendicitis comprises three days of intravenous antibiotics. Recently, it has been proposed that such antibiotic regimen should be replaced by orally administered antibiotics. The aim of this paper...... was to give an overview of studies on acute perforated appendicitis with postoperative oral antibiotics. Five studies were found in a database search covering the 1966-2009 period. There is no evidence to support a conversion of the postoperative antibiotic regimen from intravenous to oral administration...

    Full Text Available Filariasis affecting animals can rarely cause infections in human beings through the accidental bite of potential vectors. The resulting infection in man, known as zoonotic filariasis occur worldwide. Human dirofilariasis, the most common zoonotic filariasis, is caused by the filarial worm belonging to the genus Dirofilaria. Dirofilarial worms, which are recognized as pathogenic in man can cause nodular lesions in the lung, subcutaneous tissue, peritoneal cavity or eyes. Oral dirofilariasis is extremely rare and only a few cases have been documented. We report an interesting case of dirofilariasis due to Dirofilaria repens involving buccal mucosa in a patient who presented with a facial swelling. The clinical features, diagnostic issues and treatment aspects are discussed. This paper stresses the importance of considering dirofilariasis as differential diagnosis for subcutaneous swelling of the face, especially in areas where it is endemic.

  10. Oral sex, oral health and orogenital infections

    Directory of Open Access Journals (Sweden)

    Full Text Available Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    2010-01-01

    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)

    Technetium-/sup 99m/-labelled dimethly-acetanilide-iminodiacetic acid (/sup 99m/Tc-IDA) hepato-biliary imaging was evaluated for its efficacy in distinguishing acute cholecystitis from acute pancreatitis. In a retrospective review, gallbladders were demonstrated by /sup 99m/Tc-IDA in 13 of 15 patients (87%) with acute pancreatitis. This is significantly higher than reports on the frequency of gallbladder filling with oral and intravenous cholangiography in the presence of acute cholecystitis

  15. Topical or oral administration with an extract of Polypodium leucotomos prevents acute sunburn and psoralen-induced phototoxic reactions as well as depletion of Langerhans cells in human skin

    1997-01-01

    Sunburn, immune suppression, photo-aging, and skin cancers result from uncontrolled overexposure of human skin to solar ultraviolet radiation (UVR). Preventive measures, including photo-protection, are helpful and can be achieved by topical sun-screening agents. Polypodium leucotomos (PL) has been used for the treatment of inflammatory diseases and has shown some in vitro and in vivo immunomodulating properties. Its beneficial photo-protective effects in the treatment of vitiligo and its antioxidant properties encouraged us to evaluate in vivo the potentially useful photo-protective property of natural extract of PL after topical application or oral ingestion. Twenty-one healthy volunteers [either untreated or treated with oral psoralens (8-MOP or 5-MOP)] were enrolled in this study and exposed to solar radiation for evaluation of the following clinical parameters: immediate pigment darkening (IPD), minimal erythema dose (MED), minimal melanogenic dose (MMD), and minimal phototoxic dose (MPD) before and after topical or oral administration of PL. Immunohistochemical assessment of CD1a-expressing epidermal cells were also performed. PL was found to be photo-protective after topical application as well as oral administration. PL increased UV dose required for IPD (P<0.01), MED (P<0.001) and MPD (P<0.001). After oral administration of PL, MED increased 2.,8±0.59 times and MPD increased 2.75±0.5 and 6.8±1.3 times depending upon the type of psoralen used. Immunohistochemical study revealed photo-protection of Langherhans cells by oral as well as topical PL. The observed photo-protective activities of oral or topical PL reveal a new avenue in examining the potentially useful field of systemic photo-protection and suggests that PL can be used as adjunct treatment and can make photochemotherapy and phototherapy possibly safe and effective when the control of cutaneous phototoxicity to PUVA or UVB is a limiting factor in such photo-therapies.

    A 65-year-old woman presented with widespread necrotising cutaneous ulceration and oral involvement. Past history included rheumatoid arthritis, and a left nephrectomy.Examination revealed multiple violaceous undermined ulcers. Blood investigations showed an acute inflammatory response. Skin histopathology showed epidermal ulceration with acute and chronic inflammation. Direct immunofluorescence was negative. A diagnosis of pyoderma gangrenosum with oral involvement was made. Mycophenolate mofetil therapy resulted in complete resolution of her pyoderma gangrenosum. Her treatment was complicated by a left proteus mirabilis psoas abscess. This resolved following four weeks of antibiotics.Pyoderma gangrenosum with oral involvement is rare but has been linked with inflammatory bowel disease and hematological disorders. Oral pyoderma gangrenosum has not previously been described in rheumatoid arthritis. Primary psoas abscess is rare but can develop in immunocompromised patients. Proteus mirabilis has been reported in patients years after nephrectomy. This is a rare case of pyoderma gangrenosum with oral involvement.

    Full Text Available Chung M Chow1, Alexander KC Leung2, Kam L Hon11Department of Paediatrics, The Chinese University of Hong Kong, Hong Kong Special Administrative Region, PR China; 2Department of Pediatrics, The University of Calgary, Calgary, Alberta, CanadaAbstract: Acute gastroenteritis is a very common disease. It causes significant mortality in developing countries and significant economic burden to developed countries. Viruses are ­responsible for approximately 70% of episodes of acute gastroenteritis in children and rotavirus is one of the best studied of these viruses. Oral rehydration therapy is as effective as i­ntravenous therapy in treating mild to moderate dehydration in acute gastroenteritis and is strongly r­ecommended as the first line therapy. However, the oral rehydration solution is described as an underused simple solution. Vomiting is one of the main reasons to explain the underuse of oral rehydration therapy. Antiemetics are not routinely recommended in treating acute gastroenteritis, though they are still commonly prescribed. Ondansetron is one of the best studied antiemetics and its role in enhancing the compliance of oral rehydration therapy and decreasing the rate of hospitalization has been proved recently. The guidelines regarding the recommendation on antiemetics have been changed according to the evidence of these recent studies.Keywords: gastroenteritis, vomiting, antiemetic, ondansetron, rotavirus, oral rehydration therapy, intravenous therapy, guideline

  14. Efficacy of orally administered prednisolone versus partial endodontic treatment on pain reduction in emergency care of acute irreversible pulpitis of mandibular molars: study protocol for a randomized controlled trial.

    Irreversible pulpitis is a highly painful inflammatory condition of the dental pulp which represents a common dental emergency. Recommended care is partial endodontic treatment. The dental literature reports major difficulties in achieving adequate analgesia to perform this emergency treatment, especially in the case of mandibular molars. In current practice, short-course, orally administered corticotherapy is used for the management of oral pain of inflammatory origin. The efficacy of intraosseous local steroid injections for irreversible pulpitis in mandibular molars has already been demonstrated but resulted in local comorbidities. Oral administration of short-course prednisolone is simple and safe but its efficacy to manage pain caused by irreversible pulpitis has not yet been demonstrated. This trial aims to evaluate the noninferiority of short-course, orally administered corticotherapy versus partial endodontic treatment for the emergency care of irreversible pulpitis in mandibular molars. This study is a noninferiority, open-label, randomized controlled clinical trial conducted at the Bordeaux University Hospital. One hundred and twenty subjects will be randomized in two 1:1 parallel arms: the intervention arm will receive one oral dose of prednisolone (1 mg/kg) during the emergency visit, followed by one morning dose each day for 3 days and the reference arm will receive partial endodontic treatment. Both groups will receive planned complete endodontic treatment 72 h after enrollment. The primary outcome is the proportion of patients with pain intensity below 5 on a Numeric Scale 24 h after the emergency visit. Secondary outcomes include comfort during care, the number of injected anesthetic cartridges when performing complete endodontic treatment, the number of antalgic drugs and the number of patients coming back for consultation after 72 h. This randomized trial will assess the ability of short-term corticotherapy to reduce pain in irreversible

  15. USGS analysis of the Australian UNCLOS submission

    Science.gov (United States)

    Hutchinson, Deborah R.; Rowland, Robert W.

    2006-01-01

    In November 2004, the Government of Australia made a submission to the Commission on the Limits of the Continental Shelf (CLCS) for 10 extended continental shelf (ECS) regions, utilizing Article-76 of the United Nations Convention on the Law of the Sea (UNCLOS). With information provided in the Australian Executive Summary, the USGS examined the 10 regions of the submission from geological, morphological, and resource perspectives. By their own request, the Australians asked that CLCS take no action on the Australian-Antarctic Territory. The major limitation in this analysis is that no bathymetric soundings or detailed hydrographic profiles were provided in the Australian Executive Summary that might show why the Foot of the Slope (FOS) was chosen or where the 2,500-m contour is located. This represents a major limitation because more than half of the 4,205 boundary points utilize the bathymetric formula line and more than one-third of them utilize the bathymetric constraint line. CLCS decisions on the components of this submission may set a precedent for how ECSs are treated in future submissions. Some of the key decisions will cover (a) how a 'natural prolongation' of a continental margin is determined, particularly if a bathymetric saddle that appears to determine the prolongation is in deep water and is well outside of the 200-nm limit (Exmouth Plateau), (b) defining to what extent that plateaus, rises, caps, banks and spurs that are formed of oceanic crust and from oceanic processes can be considered to be 'natural prolongations' (Kerguelen Plateau), (c) to what degree UNCLOS recognizes reefs and uninhabited micro-islands (specifically, rocks and/or sand shoals) as islands that can have an EEZ (Middleton and Elizabeth Reefs north of Lord Howe Island), and (d) how the Foot of the Slope (FOS) is chosen (Great Australian Bight). The submission contains situations that are relevant to potential future U.S. submissions and are potentially analogous to certain

  16. Relation between radiotherapy-induced acute injury of mucosa of nasopharyngeal carcinoma and p53 polymorphisms

    Wang Changsheng; Xiao Shaowen; Zhang Shanwen

    2007-01-01

    Objective: To explore the relation between p53 genetic polymorphisms and radiotherapy-induced acute injury of mucosa of oral cavity mucosa. Methods: The total of 56 patients with NPC treated by radiotherapy alone or with chemoradiotherapy synchronically were genotyped for the p53 codon 72 pro-Arg SNP using PCR-RFLP assays, and were ranked according to the acute injury of oral cavity mucosa. Results: There was no difference in acute injury of oral cavity mucosa between the p53 Pro allele carriers and the other carriers (P>0.05); the high single dose (P<0.01) and concomitant chemoradiotherapy (P<0.05) resulted in increase in acute injury of oral cavity mucosa. Conclusion: Those results suggest that p53 SNP may not associate with radiotherapeutic acute injury of oral cavity mucosa. (authors)

  13. Acute calcific tendinitis of the finger--a case report.

    LENUS (Irish Health Repository)

    Ali, S N

    2004-07-01

    Acute calcific tendinitis of the hand is rare and often misdiagnosed as infection, fracture or periarthritis. It frequently occurs in peri-menopausal women and is caused by deposits of hydroxyapatite crystals. We describe acute calcific tendinitis of the flexor digitorum superficialis insertion in an elderly man taking oral anticoagulants. The differential diagnoses and recommended treatment are discussed.

  14. Incensole acetate reduces depressive-like behavior and modulates hippocampal BDNF and CRF expression of submissive animals.

    2012-12-01

    Incensole acetate (IA), a constituent of Boswellia resin ('frankincense'), was previously demonstrated to exhibit an antidepressive-like effect in the Forced Swim Test (FST) in mice following single dose administration (50 mg/kg). Here, we show that acute administration of considerably lower dose (10 mg/kg) IA to selectively bred mice, showing prominent submissive behavior, exerted significant antidepressant-like effects in the FST. Furthermore, chronic administration of 1 or 5 mg/kg per day of IA for three consecutive weeks dose- and time-dependently reduced the submissiveness of the mice in the Dominant-Submissive Relationship test, developed to screen the chronic effect of antidepressants. This behavioral effect was concomitant to reduced serum corticosterone levels, dose-dependent down-regulation of corticotropin releasing factor and up-regulation of brain derived neurotrophic factor transcripts IV and VI expression in the hippocampus. These data suggest that IA modulates the hypothalamic-pituitary-adrenal (HPA) axis and influences hippocampal gene expression, leading to beneficial behavioral effects supporting its potential as a novel treatment of depressive-like disorders.

  15. Observations of oral hygiene care interventions provided by nurses to hospitalized older people.

    Science.gov (United States)

    Coker, Esther; Ploeg, Jenny; Kaasalainen, Sharon; Carter, Nancy

    Dependent older hospitalized patients rely on nurses to assist them with the removal of plaque from their teeth, dentures, and oral cavities. Oral care interventions by 25 nurses on post-acute units, where patients have longer hospital stays, were observed during evening care. In addition to efforts to engage patients in oral care, nurses provided the following interventions: (a) supporting the care of persons with dentures; (b) supporting the care of natural teeth; (c) cleansing the tongue and oral cavity; and (d) moisturizing lips and oral tissues. Patients' oral hygiene care was supported in just over one-third of encounters. Denture care was inconsistently performed, and was infrequently followed by care of the oral cavity. Nurses did not encourage adequate self-care of natural teeth by patients, and infrequently moisturized tissues. Evidence-based oral hygiene care standards are required to assist nurses to support patients in achieving optimal oral hygiene outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

    2016-04-01

    Background and Objective Although transcatheter closure of perimembranous ventricular septal defect is emerging as an accepted, viable alternative, conduction disturbances still remain a major concern. Although steroid treatment has shown encouraging results with complete recovery, efficacy of prophylactic use of steroids is still speculative. We aim to study the mid-term outcome of perimembranous ventricular septal defect closure in children who received prophylactic oral steroids. Materials and methods A prospective study was designed and antegrade device closure was attempted in eligible children who met the following inclusion criteria: age 3-18 years and weight >10 kg, defect diameter ⩽12 mm, and symptomatic, haemodynamic changes or history of infective endocarditis. Prophylactic steroid protocol consisted of 2 weeks oral prednisolone (1 mg/kg/day) initiated immediately after the procedure, and in the event of bradyarrhythmia it was escalated to 2 mg/kg. Patients were regularly followed-up at 1, 6, and 12 months and then annually. Patients with post-procedure heart block underwent Holter monitoring after a minimum of 1 year interval. Between May, 2007 and August, 2012, successful device closure was accomplished in 290/297 patients. Mean age and weight were 9±3.12 years and 21±8.27 kg, respectively. The defect measured 5±1.38 mm on echocardiography. Mean fluoroscopy time was 12.98±8.64 minutes. Eight patients with major complications included one each with device embolisation, haemolysis, severe aortic regurgitation, and five with bradyarrhythmias, including complete atrioventricular block in three, Mobitz II in one, and bifascicular block in one. Patients with complete atrioventricular block responded to high-dose steroid and temporary pacemaker. Minor complications included post-procedure heart block (n=22) and blood loss (n=2). At 18.23±13.15 months follow-up, 8/27 (five major, 22 minor) with arrhythmia had persistent post-procedure heart block of no

    The limited number of oral vaccines currently approved for use in humans and veterinary species clearly illustrates that development of efficacious and safe oral vaccines has been a challenge not only for fish immunologists. The insufficient efficacy of oral vaccines is partly due to antigen breakdown in the harsh gastric environment, but also to the high tolerogenic gut environment and to inadequate vaccine design. In this review we discuss current approaches used to develop oral vaccines fo...

  20. Extensive review of fish embryo acute toxicities for the prediction of GHS acute systemic toxicity categories.

    2014-08-01

    Distribution and marketing of chemicals require appropriate labelling of health, physical and environmental hazards according to the United Nations global harmonisation system (GHS). Labelling for (human) acute toxicity categories is based on experimental findings usually obtained by oral, dermal or inhalative exposure of rodents. There is a strong societal demand for replacing animal experiments conducted for safety assessment of chemicals. Fish embryos are considered as alternative to animal testing and are proposed as predictive model both for environmental and human health effects. Therefore, we tested whether LC50s of the fish embryo acute toxicity test would allow effectively predicting of acute mammalian toxicity categories. A database of published fish embryo LC50 containing 641 compounds was established. For these compounds corresponding rat oral LD50 were identified resulting in 364 compounds for which both fish embryo LC50 and rat LD50 was available. Only a weak correlation of fish embryo LC50 and rat oral LD50 was obtained. Fish embryos were also not able to effectively predict GHS oral acute toxicity categories. We concluded that due to fundamental exposure protocol differences (single oral dose versus water-borne exposure) a reverse dosimetry approach is needed to explore the predictive capacity of fish embryos.

    Thomas, S H; Stone, C K

    1994-01-01

    Sodium bicarbonate is an extremely well-known agent that historically has been used for a variety of medical conditions. Despite the widespread use of oral bicarbonate, little documented toxicity has occurred, and the emergency medicine literature contains no reports of toxicity caused by the ingestion of baking soda. Risks of acute and chronic oral bicarbonate ingestion include metabolic alkalosis, hypernatremia, hypertension, gastric rupture, hyporeninemia, hypokalemia, hypochloremia, intravascular volume depletion, and urinary alkalinization. Abrupt cessation of chronic excessive bicarbonate ingestion may result in hyperkalemia, hypoaldosteronism, volume contraction, and disruption of calcium and phosphorus metabolism. The case of a patient with three hospital admissions in 4 months, all the result of excessive oral intake of bicarbonate for symptomatic relief of dyspepsia is reported. Evaluation and treatment of patients with acute bicarbonate ingestion is discussed.

    Oral cancer is one of the 10 most common cancers in the world, with a delayed clinical detection, poor prognosis, without specific biomarkers for the disease and expensive therapeutic alternatives. This review aims to present the fundamental aspects of this cancer, focused on squamous cell carcinoma of the oral cavity (OSCC), moving from its definition and epidemiological aspects, addressing the oral carcinogenesis, oral potentially malignant disorders, epithelial precursor lesions and experimental methods for its study, therapies and future challenges. Oral cancer is a preventable disease, risk factors and natural history is already being known, where biomedical sciences and dentistry in particular are likely to improve their poor clinical indicators.

    2016-11-01

    Oral cancer is considered as a serious health problem resulting in high morbidity and mortality. Early detection and prevention play a key role in controlling the burden of oral cancer worldwide. The five-year survival rate of oral cancer still remains low and delayed diagnosis is considered as one of the major reasons. This increases the demand for oral screening. Currently, screening of oral cancer is largely based on visual examination. Various evidence strongly suggest the validity of visual inspection in reducing mortality in patients at risk for oral cancer. Simple visual examination is accompanied with adjunctive techniques for subjective interpretation of dysplastic changes. These include toluidine blue staining, brush biopsy, chemiluminescence and tissue autofluorescence. This review highlights the efficacy of various diagnostic methods in screening of oral cancer. © 2016 Old City Publishing, Inc.

  8. Oral biopsy: Oral pathologist′s perspective

    Directory of Open Access Journals (Sweden)

    K L Kumaraswamy

    2012-01-01

    Full Text Available Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

    AGU's international interdisciplinary journal Water Resources Research (WRR) publishes original contributions in hydrology; the physical, chemical, and biological sciences; and the social and policy sciences, including economics, systems analysis, sociology, and law. With the rising relevance of water economics and related social sciences, the editors of WRR continue to encourage submissions on economics and policy. WRR was originally founded in the mid 1960s by Walter Langbein and economist Allen Kneese. Several former WRR editors have been economists—including David Brookshire, Ron Cummings, and Chuck Howe—and many landmark articles in water economics have been published in WRR.

    Acute Lymphoblastic Leukemia (ALL) accounts for 70-80% of childhood leukemias. One of the main treatments for ALL is chemotherapy. One of the most common side effects of chemotherapy is oral mucositis. Oral mucositis is an inflammation of the oral mucosa which leads to erythematous and ulcerative lesions. This study describes the incidence of oral mucositis in children with ALL undergoing chemotherapy in Haji Adam Malik Hospital during 2008-2012. This is a descriptive study with cross- sec...

  12. Oral manifestations of lupus.

    2018-02-01

    Mucosal involvement is commonly seen in patients with lupus; however, oral examination is often forgotten. Squamous cell carcinoma arising within oral lupoid plaques has been described, emphasizing the importance of identifying and treating oral lupus. We undertook a retrospective single-centre study looking at oral findings in patients attending our multidisciplinary lupus clinic between January 2015 and April 2016. A total of 42 patients were included. The majority of patients were female (88%) and had a diagnosis of discoid lupus erythematosus (62%). Half of the patients had positive oral findings, 26% had no oral examination documented, and 24% had documented normal oral examinations. Our findings suggest that oral pathology is common in this cohort of patients. Regular oral examination is warranted to identify oral lupus and provide treatment. Associated diseases such as Sjogren's syndrome may also be identified. Patients should be encouraged to see their general dental practitioners on a regular basis for mucosal review. Any persistent ulcer that fails to respond to treatment or hard lump needs urgent histopathological evaluation to exclude malignant transformation to squamous cell carcinoma.

    2009-01-01

    Full Text Available Patients receiving radiotherapy or chemotherapy will receive some degree of oral mucositis The incidence of oral mucositis was especially high in patients: (i With primary tumors in the oral cavity, oropharynx, or nasopharynx; (ii who also received concomitant chemotherapy; (iii who received a total dose over 5,000 cGy; and (iv who were treated with altered fractionation radiation schedules. Radiation-induced oral mucositis affects the quality of life of the patients and the family concerned. The present day management of oral mucositis is mostly palliative and or supportive care. The newer guidelines are suggesting Palifermin, which is the first active mucositis drug as well as Amifostine, for radiation protection and cryotherapy. The current management should focus more on palliative measures, such as pain management, nutritional support, and maintenance, of good oral hygiene

Method: A retrospective study was performed on all routine oral surgery referrals received between 2014 and 2015 at both Halmstad Hospital and Växjö Hospital. A total of 1,891 referral letters were assessed for their quality against a predetermined checklist of basic requirements of a satisfactory referral. The referrals were also categorized according to if it was sent by a male, female, private dental service, or the Swedish Public Dental Health service. Results: A diagnosis was missing in 30% of all referrals. Radiographs and information about previous radiographic examinations were not included in 10% of the referrals. Of those referrals that included radiographs, only around half were deemed adequate for diagnostic purposes. The presenting complaint was missing in 40% of all referrals. Current medical history was absent in 40% and current medication was omitted in 60% of the referrals. Information about tobacco use was only included in 10% of all referrals. Overall, female referrers performed better than male colleagues. Private referrals more regularly included information about diagnosis, previous treatment, and current medication. On the other hand, referrals from the public dental health service more frequently included radiographs, tobacco use, and current medical history. Conclusion: There is plenty of room for improving the standards of oral surgery referrals. We suggest that future electronic referral systems should only allow for submission once all of the essential information has been considered.

    Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the...

  17. Towards understanding oral health.

    Science.gov (United States)

    Zaura, Egija; ten Cate, Jacob M

    2015-01-01

    During the last century, dental research has focused on unraveling the mechanisms behind various oral pathologies, while oral health was typically described as the mere absence of oral diseases. The term 'oral microbial homeostasis' is used to describe the capacity of the oral ecosystem to maintain microbial community stability in health. However, the oral ecosystem itself is not stable: throughout life an individual undergoes multiple physiological changes while progressing through infancy, childhood, adolescence, adulthood and old age. Recent discussions on the definition of general health have led to the proposal that health is the ability of the individual to adapt to physiological changes, a condition known as allostasis. In this paper the allostasis principle is applied to the oral ecosystem. The multidimensionality of the host factors contributing to allostasis in the oral cavity is illustrated with an example on changes occurring in puberty. The complex phenomenon of oral health and the processes that prevent the ecosystem from collapsing during allostatic changes in the entire body are far from being understood. As yet individual components (e.g. hard tissues, microbiome, saliva, host response) have been investigated, while only by consolidating these and assessing their multidimensional interactions should we be able to obtain a comprehensive understanding of the ecosystem, which in turn could serve to develop rational schemes to maintain health. Adapting such a 'system approach' comes with major practical challenges for the entire research field and will require vast resources and large-scale multidisciplinary collaborations. 2015 S.

    Despite impressive worldwide improvements in oral health, inequalities in oral health status among and within countries remain a daunting public health challenge. Oral health inequalities arise from a complex web of health determinants, including social, behavioral, economic, genetic, environmental, and health system factors. Eliminating these inequalities cannot be accomplished in isolation of oral health from overall health, or without recognizing that oral health is influenced at multiple individual, family, community, and health systems levels. For several reasons, this is an opportune time for global efforts targeted at reducing oral health inequalities. Global health is increasingly viewed not just as a humanitarian obligation, but also as a vehicle for health diplomacy and part of the broader mission to reduce poverty, build stronger economies, and strengthen global security. Despite the global economic recession, there are trends that portend well for support of global health efforts: increased globalization of research and development, growing investment from private philanthropy, an absolute growth of spending in research and innovation, and an enhanced interest in global health among young people. More systematic and far-reaching efforts will be required to address oral health inequalities through the engagement of oral health funders and sponsors of research, with partners from multiple public and private sectors. The oral health community must be “at the table” with other health disciplines and create opportunities for eliminating inequalities through collaborations that can harness both the intellectual and financial resources of multiple sectors and institutions.

  19. Oral microbiota and cancer

    Directory of Open Access Journals (Sweden)

    2010-08-01

    Full Text Available Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the complex metabolic pathways and may thus be involved in carcinogenesis. Poor oral health associates statistically with prevalence of many types of cancer, such as pancreatic and gastrointestinal cancer. Furthermore, several oral micro-organisms are capable of converting alcohol to carcinogenic acetaldehyde which also may partly explain the known association between heavy drinking, smoking, poor oral health and the prevalence of oral and upper gastrointestinal cancer. A different problem is the cancer treatment-caused alterations in oral microbiota which may lead to the emergence of potential pathogens and subsequent other systemic health problems to the patients. Hence clinical guidelines and recommendations have been presented to control oral microbiota in patients with malignant disease, but also in this area the scientific evidence is weak. More controlled studies are needed for further conclusion.

  1. Oral candidosis in relation to oral immunity.

    Symptomatic oral infection with Candida albicans is characterized by invasion of the oral epithelium by virulent hyphae that cause tissue damage releasing the inflammatory mediators that initiate and sustain local inflammation. Candida albicans triggers pattern-recognition receptors of keratinocytes, macrophages, monocytes and dendritic cells, stimulating the production of IL-1β, IL-6 and IL-23. These cytokines induce the differentiation of Th17 cells and the generation of IL-17- and/or IL-22-mediated antifungal protective immuno-inflammatory responses in infected mucosa. Some immune cells including NKT cells, γδ T cells and lymphoid cells that are innate to the oral mucosa have the capacity to produce large quantities of IL-17 in response to C. albicans, sufficient to mediate effective protective immunity against C. albicans. On the other hand, molecular structures of commensal C. albicans blastoconidia, although detected by pattern-recognition receptors, are avirulent, do not invade the oral epithelium, do not elicit inflammatory responses in a healthy host, but induce regulatory immune responses that maintain tissue tolerance to the commensal fungi. The type, specificity and sensitivity of the protective immune response towards C. albicans is determined by the outcome of the integrated interactions between the intracellular signalling pathways of specific combinations of activated pattern-recognition receptors (TLR2, TLR4, Dectin-1 and Dectin-2). IL-17-mediated protective immune response is essential for oral mucosal immunity to C. albicans infection. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    comparing acupuncture plus another treatment versus another treatment alone. Data collection and analysis We used standard methodological procedures used by Cochrane. Main results We included 6 RCTs with a total of 531 participants from China. The mean age of the participants ranged from 18 to 28 years. Four RCTs included participants diagnosed with initial acute hordeolum with a duration of less than seven days; one RCT included participants diagnosed with initial acute hordeolum without specifying the duration; and one RCT included participants with recurrent acute hordeolum with a mean duration of 24 days. About 55% (291/531) of participants were women. Three RCTs included participants with either external or internal hordeolum; one RCT included participants with only external hordeolum; and two RCTs did not specify the type of hordeolum. Follow-up was no more than seven days after treatment in all included RCTs; no data were available for long-term outcomes. Overall, the certainty of the evidence for all outcomes was low to very low, and we judged all RCTs to be at high or unclear risk of bias. Three RCTs compared acupuncture with conventional treatments. We did not pool the data from these RCTs because the conventional treatments were not similar among trials. Two trials showed that resolution of acute hordeolum was more likely in the acupuncture group when compared with topical antibiotics (1 RCT; 32 participants; risk ratio (RR) 3.60; 95% confidence interval (CI) 1.34 to 9.70; low-certainty of evidence) or oral antibiotics plus warm compresses (1 RCT; 120 participants; RR 1.45; 95% CI 1.18 to 1.78; low-certainty of evidence). In the third trial, little or no difference in resolution of hordeolum was observed when acupuncture was compared with topical antibiotics plus warm compresses (1 RCT; 109 participants; RR 1.00; 95% CI 0.96 to 1.04; low-certainty of evidence). One RCT mentioned adverse outcomes, stating that there was no adverse event associated with acupuncture

    Geurts, Dorien; Steyerberg, Ewout W; Moll, Henriëtte; Oostenbrink, Rianne

    2017-11-01

    Oral rehydration is the standard in most current guidelines for young children with acute gastroenteritis (AGE). Failure of oral rehydration can complicate the disease course, leading to morbidity due to severe dehydration. We aimed to identify prognostic factors of oral rehydration failure in children with AGE. A prospective, observational study was performed at the Emergency department, Erasmus Medical Centre, Rotterdam, The Netherlands, 2010-2012, including 802 previously healthy children, ages 1 month to 5 years with AGE. Failure of oral rehydration was defined by secondary rehydration by a nasogastric tube, or hospitalization or revisit for dehydration within 72 hours after initial emergency department visit. We observed 167 (21%) failures of oral rehydration in a population of 802 children with AGE (median 1.03 years old, interquartile range 0.4-2.1; 60% boys). In multivariate logistic regression analysis, independent predictors for failure of oral rehydration were a higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score. Early recognition of young children with AGE at risk of failure of oral rehydration therapy is important, as emphasized by the 21% therapy failure in our population. Associated with oral rehydration failure are higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score.

  5. Acute Bacterial Prostatitis: Diagnosis and Management.

    Science.gov (United States)

    Coker, Timothy J; Dierfeldt, Daniel M

    2016-01-15

    Acute bacterial prostatitis is an acute infection of the prostate gland that causes pelvic pain and urinary tract symptoms, such as dysuria, urinary frequency, and urinary retention, and may lead to systemic symptoms, such as fevers, chills, nausea, emesis, and malaise. Although the true incidence is unknown, acute bacterial prostatitis is estimated to comprise approximately 10% of all cases of prostatitis. Most acute bacterial prostatitis infections are community acquired, but some occur after transurethral manipulation procedures, such as urethral catheterization and cystoscopy, or after transrectal prostate biopsy. The physical examination should include abdominal, genital, and digital rectal examination to assess for a tender, enlarged, or boggy prostate. Diagnosis is predominantly made based on history and physical examination, but may be aided by urinalysis. Urine cultures should be obtained in all patients who are suspected of having acute bacterial prostatitis to determine the responsible bacteria and its antibiotic sensitivity pattern. Additional laboratory studies can be obtained based on risk factors and severity of illness. Radiography is typically unnecessary. Most patients can be treated as outpatients with oral antibiotics and supportive measures. Hospitalization and broad-spectrum intravenous antibiotics should be considered in patients who are systemically ill, unable to voluntarily urinate, unable to tolerate oral intake, or have risk factors for antibiotic resistance. Typical antibiotic regimens include ceftriaxone and doxycycline, ciprofloxacin, and piperacillin/tazobactam. The risk of nosocomial bacterial prostatitis can be reduced by using antibiotics, such as ciprofloxacin, before transrectal prostate biopsy.

    A 54-year-old woman with adenocarcinoma of the lung and lymph node metastasis experienced nystagmus and cerebellar ataxia 2 weeks after initiating nivolumab therapy. An evaluation for several autoimmune-related antibodies and paraneoplastic syndrome yielded negative results. We eventually diagnosed the patient with nivolumab-induced acute cerebellar ataxia, after excluding other potential conditions. Her ataxic gait and nystagmus resolved shortly after intravenous steroid pulse therapy followed by the administration of decreasing doses of oral steroids. Nivolumab, an immune checkpoint inhibitor, is known to induce various neurological adverse events. However, this is the first report of acute cerebellar ataxia associated with nivolumab treatment.

  10. GHS additivity formula: can it predict the acute systemic toxicity of agrochemical formulations that contain acutely toxic ingredients?

    Science.gov (United States)

    Van Cott, Andrew; Hastings, Charles E; Landsiedel, Robert; Kolle, Susanne; Stinchcombe, Stefan

    2018-02-01

    In vivo acute systemic testing is a regulatory requirement for agrochemical formulations. GHS specifies an alternative computational approach (GHS additivity formula) for calculating the acute toxicity of mixtures. We collected acute systemic toxicity data from formulations that contained one of several acutely-toxic active ingredients. The resulting acute data set includes 210 formulations tested for oral toxicity, 128 formulations tested for inhalation toxicity and 31 formulations tested for dermal toxicity. The GHS additivity formula was applied to each of these formulations and compared with the experimental in vivo result. In the acute oral assay, the GHS additivity formula misclassified 110 formulations using the GHS classification criteria (48% accuracy) and 119 formulations using the USEPA classification criteria (43% accuracy). With acute inhalation, the GHS additivity formula misclassified 50 formulations using the GHS classification criteria (61% accuracy) and 34 formulations using the USEPA classification criteria (73% accuracy). For acute dermal toxicity, the GHS additivity formula misclassified 16 formulations using the GHS classification criteria (48% accuracy) and 20 formulations using the USEPA classification criteria (36% accuracy). This data indicates the acute systemic toxicity of many formulations is not the sum of the ingredients' toxicity (additivity); but rather, ingredients in a formulation can interact to result in lower or higher toxicity than predicted by the GHS additivity formula.

    Bui, Thanh Cong; Markham, Christine M; Ross, Michael Wallis; Mullen, Patricia Dolan

    2013-09-01

    Oral human papillomavirus (HPV) infection is the cause of 40% to 80% of oropharyngeal cancers; yet, no published study has examined the role of oral health in oral HPV infection, either independently or in conjunction with other risk factors. This study examined the relation between oral health and oral HPV infection and the interactive effects of oral health, smoking, and oral sex on oral HPV infection. Our analyses comprised 3,439 participants ages 30 to 69 years for whom data on oral HPV and oral health were available from the nationally representative 2009-2010 National Health and Nutrition Examination Survey. Results showed that higher unadjusted prevalence of oral HPV infection was associated with four measures of oral health, including self-rated oral health as poor-to-fair [prevalence ratio (PR) = 1.56; 95% confidence interval (CI), 1.25-1.95], indicated the possibility of gum disease (PR = 1.51; 95% CI, 1.13-2.01), reported use of mouthwash to treat dental problems in the past week (PR = 1.28; 95% CI, 1.07-1.52), and higher number of teeth lost (Ptrend = 0.035). In multivariable logistic regression models, oral HPV infection had a statistically significant association with self-rated overall oral health (OR = 1.55; 95% CI, 1.15-2.09), independent of smoking and oral sex. In conclusion, poor oral health was an independent risk factor of oral HPV infection, irrespective of smoking and oral sex practices. Public health interventions may aim to promote oral hygiene and oral health as an additional measure to prevent HPV-related oral cancers.

  12. Association of Oral Lichen Planus with Chronic C Hepatitis. Review of the Data in Literature

    GHEORGHE, Carmen; MIHAI, Lelia; PARLATESCU, Ioanina; TOVARU, Serban

    2014-01-01

    The relationship between chronic hepatitis C virus infection (HCV) and oral lichen planus (OLP) is a current topic in the field of oral medicine. Many studies of this association have been made over time. The geographic variation of the hepatitis C prevalence proved to be an important factor influencing the statistical results of the studies analyzing the association of the oral plan lichen with the hepatitis C virus. Approaching this issue is not to be neglected. Treatment outcomes in patients with oral lichen planus associated with chronic hepatitis C virus are often unsatisfactory compared to patients suffering from idiopathic oral lichen planus. Also, the evolution of oral lesions is often fluctuating, with repeated periods of relapse according to the degree of liver function decompensation. Background therapy for liver disease itself may influence lichen planus lesions. Thus, during therapy with interferon and ribavirin oral lesions may appear or become acute. PMID:25553136

  14. Thirst sensation and oral dryness following alcohol intake

    Directory of Open Access Journals (Sweden)

    Kiyotoshi Inenaga

    2017-08-01

    Full Text Available Substantial acute and chronic intakes of alcohol or ethanol (EtOH severely influence oral sensations, such as thirst and oral dryness (dry mouth, xerostomia. Thirst sensation and oral dryness are primarily caused by the activation of neurons in brain regions, including the circumventricular organs and hypothalamus, which are referred to as the dipsogenic center, and by a decrease in salivary secretion, respectively. The sensation of thirst experienced after heavy-alcohol drinking is widely regarded as a consequence of EtOH-induced diuresis; however, EtOH in high doses induces anti-diuresis. Recently, it has been proposed that the ethanol metabolite acetaldehyde induces thirst via two distinct processes in the central nervous system from EtOH-induced diuresis, based on the results of animal experiments. The present review describes new insights regarding the induction mechanism of thirst sensation and oral dryness after drinking alcohol.

    2018-02-01

    Although most cases of acute gastroenteritis require minimal medical intervention, severe dehydration and hypoglycemia may develop in cases of prolonged vomiting and diarrhea. The mainstay of treatment for mild-to-moderately dehydrated patients with acute gastroenteritis should be oral rehydration solution. Antiemetics allow for improved tolerance of oral rehydration solution, and, when used appropriately, can decrease the need for intravenous fluids and hospitalization. This issue reviews the common etiologies of acute gastroenteritis, discusses more-severe conditions that should be considered in the differential diagnosis, and provides evidence-based recommendations for management of acute gastroenteritis in patients with mild-to-moderate dehydration, severe dehydration, and hypoglycemia.

    Full Text Available Aim: the study aims to observe the response to treatment with ORS only or ORS + gelatin tannate in two cohorts of pediatric patients with acute diarrhea, with the primary efficacy endpoint being the number of stools at 12 hours from baseline. Methods: children aged 3 months to 12 years were included in the study. Only children with acute diarrhea, more than 3 liquid stools, and duration inferior to 72 h were included. Number of stools was recorded as absolute number, categorized as ≤ 3 and ≥ 4 stools over 12 hours, and as a stool decrease index (SDI. Other clinical variables were recorded, including weight, fever, vomiting, stool characteristics, and signs of peritonitis/sepsis. Results: baseline characteristics for the two populations included a mean age of 2.3 years in the ORS group and 2.6 years in the ORS + gelatin tannate group. Children younger than 2 years represented 59.8 and 54.3% in the ORS and ORS + gelatin tannate groups, respectively. Clinical variables such as vomiting, dehydration, weigth, and stool decrease index were used to compare the two groups. We found a statistical significant difference between the two groups (p Objetivo: el estudio tiene como objetivo observar la respuesta al tratamiento con SRO o SRO + tanato de gelatina en dos cohortes de pacientes pediátricos que presentan diarrea aguda, siendo el número de deposiciones a las 12 horas desde el tratamiento inicial el criterio principal de valoración de la eficacia.

    Full Text Available Acute myeloid leukemia (AML is a malignant neoplasm of myeloid series defined by the presence of immature blast cells (<30% in peripheral circulation. Oral manifestations are the potential indicators of systemic health and disease. Oral cavity is the frequently and early involved sites in AML. Gingival overgrowth due to leukemia is one such condition encountered by periodontists. Hence, understanding, identifying, and correlating oral manifestations with systemic diseases are the ultimate responsibility of every dental clinician because of its lethal and unpredictable course. In the present case, we are discussing an undiagnosed case of AML who presented to us with oral complaints.

  6. Therapeutic management of radiation-induced oral mucositis

    International Nuclear Information System (INIS)

    Doerr, W.; Doelling-Jochem, I.; Baumann, M.; Herrmann, T.

    1997-01-01

    Background: Acute reactions of oral mucosa are a frequent side effect of radiotherapy, which often necessitates interruption of the treatment. Marked proliferation of tumor stem cells during treatment interruptions may occur in squamous cell carcinomata, which represent the majority of tumors in the head and neck area. Hence a fatal consequence of treatment breaks may be a significant decrease in tumor cure rates. Furthermore, marked acute responses frequently result in increased late sequelae ('consequential damage'). Therefore, amelioration of the mucosal response aiming at avoiding treatment breaks and at reduction of late reactions coul definitely increase the therapeutic success of radiation treatment. Results: A variety of prophylactic and therapeutic methods have been proposed for the management of acute radiation reactions of the oral mucosa. Frequently, their efficiacy has been established for chemotherapy or in combination with other immunosuppressive treatments. Hence, systemical rather than local effects have to be considered. Conclusions: In general, prophylaxis of oral mucositis is mainly based on dental restoration or edentation, in combination with frequent oral hygienic measures after the meals and with antiseptic mouthwashes. Intensive personal care is recommended. The necessity of a percutaneous endoscopic gastrostoma is dependent on the status of the patient and on size and localization of the treatment area, i.e. the impairment of food uptake which is to be expected. Therapeutic intervention is restricted to local or systemic treatment of pain and local application of antimycotics and antibiotics. (orig./VHE) [de

  7. Maintaining women's oral health.

    McCann, A L; Bonci, L

    2001-07-01

    Women must adopt health-promoting strategies for both general health and the oral cavity, because the health of a woman's body and oral cavity are bidirectional. For general health-maintenance strategies, dental practitioners should actively advise women to minimize alcohol use, abstain from or cease smoking, stay physically active, and choose the right foods to nourish both the body and mind. For oral health-maintenance strategies, dental practitioners should advise women on how to prevent or control oral infections, particularly dental caries and periodontal diseases. Specifically, women need to know how to remove plaque from the teeth mechanically, use appropriate chemotherapeutic agents and dentifrices, use oral irrigation, and control halitosis. Dental practitioners also need to stress the importance of regular maintenance visits for disease prevention. Adolescent women are more prone to gingivitis and aphthous ulcers when they begin their menstrual cycles and need advice about cessation of tobacco use, mouth protection during athletic activities, cleaning orthodontic appliances, developing good dietary habits, and avoiding eating disorders. Women in early to middle adulthood may be pregnant or using oral contraceptives with concomitant changes in oral tissues. Dental practitioners need to advise them how to take care of the oral cavity during these changes and how to promote the health of their infants, including good nutrition. Older women experience the onset of menopause and increased vulnerability to osteoporosis. They may also experience xerostomia and burning mouth syndrome. Dental practitioners need to help women alleviate these symptoms and encourage them to continue good infection control and diet practices.

    Full Text Available The paper analyzes a rise in the incidence of oral cancer in the Rostov Region since the 1990s. The study has indicated that this rise is associated with regional population growth due to the forced migrants after the collapse of the USSR. Financial problems, unbalanced nutrition, poor oral hygiene, and depression in this group of patients have contributed to the higher incidence of precancers and cancers.

  9. Oral vs. salivary diagnostics

    Marques, Joana; Corby, Patricia M.; Barber, Cheryl A.; Abrams, William R.; Malamud, Daniel

    2015-05-01

    The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro- and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.

    2016-08-01

    Full Text Available Objective: Pinus eldarica (P. eldarica is one of the most common pines in Iran which has various bioactive constituents and different uses in traditional medicine. Since there is no documented evidence for P. eldarica safety, the acute and sub-acute oral toxicities of hydroalcoholic extract of P. eldarica bark were investigated in male and female Wistar rats in this study. Materials and Methods: In the acute study, a single dose of extract (2000 mg/kg was orally administered and animals were monitored for 7 days. In the sub-acute study, repeated doses (125, 250 and 500 mg/kg/day of the extract were administered for 28 days and biochemical, hematological and histopathological parameters were evaluated. Results: Our results showed no sign of toxicity and no mortality after single or repeated administration of P. eldarica. The median lethal dose (LD50 of P. eldarica was determined to be higher than 2000 mg/kg. The mean body weight and most of the biochemical and hematological parameters showed normal levels.  There were only significant decreases in serum triglyceride levels at the doses of 250 and 500 mg/kg of the extract in male rats (pConclusion: Oral administration of the hydroalcoholic extract of P. eldarica bark may be considered as relatively non-toxic particularly at the doses of 125 and 250 mg/kg.

  15. Ethnicity and oral cancer.

    Scully, C; Bedi, R

    2000-09-01

    Oral squamous-cell carcinoma, the main type of oral cancer, is among the ten most common cancers in the world. The aims of this paper were first, to consider whether there was evidence of marked ethnic variations in the incidence, management, and survival of oral cancer, and then, to review possible explanations for these variations. Evidence from the literature suggests that there is marked, inter-country variation in both the incidence and mortality from oral cancer. There is also growing evidence of intracountry ethnic differences, mostly reported in the UK and USA. These variations among ethnic groups have been attributed mainly to specific risk factors, such as alcohol and tobacco (smoking and smokeless), but dietary factors and the existence of genetic predispositions may also play a part. Variations in access to care services are also an apparent factor. The extent of ethnic differences in oral cancer is masked by the scarcity of information available. Where such data are accessible, there are clear disparities in both incidence and mortality of oral cancer between ethnic groups.

    chronic hypoxia and experimental pancreatitis could play role in the physiology and pathophysiology of the pancreas. The significant changes of pancreatic renin-angiotensin system may have clinical relevance in acute pancreatitis and hypoxia-induced injury in the pancreas. Detection of the pancreatic polypeptide level, oral glucose tolerance test assesses the state of the pancreas after acute pancreatitis in the long term. Conclusions: The biggest impact in the hormonal secretion of pancreatic islet has pancreatic renin-angiotensin system. Permissive factor for pancreatic endocrine dysfunction is chronic hypoxia due to violation of organ perfusion. Endocrine function of the pancreas are more affected after resection treatment of acute pancreatitis. Serological tests of pancreatic polypeptide promising for early diagnosis and prediction of the outcome of acute pancreatitis.

  20. Social dominance and forceful submission fantasies: feminine pathology or power?

    Science.gov (United States)

    Hawley, Patricia H; Hensley, William A

    2009-01-01

    This study addresses forceful submission fantasies in men and women. Although many approaches implicitly or explicitly cast women's force fantasies in a pathological light, this study seeks to explore the associations of such fantasy to female power. By adopting an evolutionary meta-theoretical perspective (and a resource control theory perspective), it was hypothesized that highly agentic, dominant women prefer forceful submission fantasies (more than subordinate women) as a means to connect them to agentic, dominant men. In addition, it is suggested that dominant women would ascribe a meaning to the object of the fantasy different from that assigned by subordinate women (i.e., "warrior lover" vs. "white knight"). Two studies were conducted with nearly 900 college students (men and women) from a large Midwestern university. Hypotheses were largely supported. Analysis of meaning supports theoretical perspectives proposing that forceful submission reflects desires for sexual power on behalf of the fantasist. Implications for evolutionary approaches to human mate preferences are discussed.

    Full Text Available Oral care is a crucial routine for patients with dysphagia that, when completed routinely, can prevent the development of aspiration pneumonia. There is no standardised protocol for oral care within government hospitals in South Africa. This study aimed to investigate the outcome of an oral care protocol. Participants were patients with oropharyngeal dysphagia, with either stroke or traumatic brain injury as the underlying medical pathology, and nurses. All participants were recruited from one tertiary level government hospital in Gauteng, South Africa. 139 nurses participated in the study and received training on the oral care protocol. There were two groups of participants with oropharyngeal dysphagia. Group one (study group, n = 23 was recruited by consecutive sampling, received regular oral care and were not restricted from drinking water; however, all other liquids were restricted. Group two (comparison group, n = 23 was recruited via a retrospective record review, received inconsistent oral care and were placed on thickened liquids or liquid restricted diets. Results showed that a regimen of regular oral care and free water provision when combined with dysphagia intervention did prevent aspiration pneumonia in patients with oropharyngeal dysphagia. The article highlights two key findings: that regular and routine oral care is manageable within an acute government hospital context and a strict routine of oral care can reduce aspiration pneumonia in patients with oropharyngeal dysphagia. An implication from these findings is confirmation that teamwork in acute care settings in developing contexts must be prioritised to improve dysphagia management and patient prognosis.

    Understanding more about the efficacy and safety of oral second-generation antipsychotic medications in reducing the symptoms of acute agitation could improve the treatment of psychiatric emergencies. The objective of this scoping review was to examine the evidence base underlying expert consensus panel recommendations for the use of oral second-generation antipsychotics to treat acute agitation in mentally ill patients. The Cochrane Schizophrenia Group's Study-Based Register was searched for randomized controlled trials comparing oral second-generation antipsychotics, benzodiazepines, or first-generation antipsychotics with or without adjunctive benzodiazepines, irrespective of route of administration of the drug being compared. Six articles were included in the final review. Two oral second-generation antipsychotic medications were studied across the six included trials. While the studies had relatively small sample sizes, oral second-generation antipsychotics were similarly effective to intramuscular first-generation antipsychotics in treating symptoms of acute agitation and had similar side-effect profiles. This scoping review identified six randomized trials investigating the use of oral second-generation antipsychotic medications in the reduction of acute agitation among patients experiencing psychiatric emergencies. Further research will be necessary to make clinical recommendations due to the overall dearth of randomized trials, as well as the small sample sizes of the included studies.

    Full Text Available Objective: The present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of Crocus sativus L. (saffron using mice in two different regimens of acute and sub-acute administration. Material and Methods: In acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p. were evaluated using forced swim test (FST. In sub-acute study (21 times with 24-h intervals, antidepressant-like effects of oral administration of drugs were examined using FST and tail suspension test (TST. Locomotor activity and motor coordination were studied using open field and rotarod tests, respectively. Results: Acute treatment with crocin (40 mg/kg and crocetin (20 and 40 mg/kg produced antidepressant-like effect in FST without affecting the baseline locomotion in mice. Sub-acute oral administration of crocin significantly decreased immobility time only at the highest dose (100 mg/kg. Crocetin (12.5, 25 and 50 mg/kg was able to decrease immobility time in FST and TST. Locomotor activity and coordination of mice were not affected by crocin or crocetin. Conclusion: Since higher doses of crocin was required to show antidepressant effects, more efficacy of crocetin may be concluded. This observation provides further support for metabolism of crocin to crocetin following oral administration.

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    The book first presents the anatomy and physiology of the abdomen and continues with chapters discussing clinical and laboratory aspects and a suitable order of diagnostic examinations with reference to the acute processes, explaining the diagnostic tools: ultrasonography, radiography including angiography and CT, tapping techniques and endoscopy together with their basic principles, examination techniques, and diagnosis. One chapter presents a complete survey of the processes involving the entire abdomen - as e.g. peritonitis, ileus, abdominal trauma, intraperitoneal hemorrage. This chapter profoundly discusses the diagnostics and therapies including emergency measures and surgery. Problems requiring consultation among varous specialists, in internal medicine, gynecology, urology, or pediatrics, are discussed in great detail. Information for the anesthetist is given for cases of emergency. More than one third of the book is devoted to organ-specific information, dicussing the pathogenesis, diagnostics, and therapy of the oesophagus, stomach, large and small intestine, bile ducts, pankreas, liver, spleen, and the abdominal vessels and the abdominal wall.

    Human oral bacteria interact with their environment by attaching to surfaces and establishing mixed-species communities. As each bacterial cell attaches, it forms a new surface to which other cells can adhere. Adherence and community development are spatiotemporal; such order requires communication. The discovery of soluble signals, such as autoinducer-2, that may be exchanged within multispecies communities to convey information between organisms has emerged as a new research direction. Direct-contact signals, such as adhesins and receptors, that elicit changes in gene expression after cell-cell contact and biofilm growth are also an active research area. Considering that the majority of oral bacteria are organized in dense three-dimensional biofilms on teeth, confocal microscopy and fluorescently labeled probes provide valuable approaches for investigating the architecture of these organized communities in situ. Oral biofilms are readily accessible to microbiologists and are excellent model systems for studies of microbial communication. One attractive model system is a saliva-coated flowcell with oral bacterial biofilms growing on saliva as the sole nutrient source; an intergeneric mutualism is discussed. Several oral bacterial species are amenable to genetic manipulation for molecular characterization of communication both among bacteria and between bacteria and the host. A successful search for genes critical for mixed-species community organization will be accomplished only when it is conducted with mixed-species communities. PMID:12209001

Preventive measures during pregnancy mean usage of fluorides, special dietary measures and increased oral hygiene habits. Preventive measures in pregnant women have one goal: providing conditions for development of fetal teeth as well as preventing tooth decay in pregnant women. The optimal period for introducing preventive measures is the first trimester of pregnancy. Because of hormonal alterations there is an increased incidence of dental diseases: gingivitis and low salivary pH (inflammation and bleeding gums). Eating habits of pregnant women may lead to frequent snacking on candy or other decay-promoting foods, thereby increasing the risk of caries. However, very poor oral health, possible dental complications and their consequences to the health as well as emotional status represent very strong reasons for activation of dental health care in this period.

  10. The Oral Microbiota.

    The oral microbiota represents an important part of the human microbiota, and includes several hundred to several thousand diverse species. It is a normal part of the oral cavity and has an important function to protect against colonization of extrinsic bacteria which could affect systemic health. On the other hand, the most common oral diseases caries, gingivitis and periodontitis are based on microorganisms. While (medical) research focused on the planktonic phase of bacteria over the last 100 years, it is nowadays generally known, that oral microorganisms are organised as biofilms. On any non-shedding surfaces of the oral cavity dental plaque starts to form, which meets all criteria for a microbial biofilm and is subject to the so-called succession. When the sensitive ecosystem turns out of balance - either by overload or weak immune system - it becomes a challenge for local or systemic health. Therefore, the most common strategy and the golden standard for the prevention of caries, gingivitis and periodontitis is the mechanical removal of this biofilms from teeth, restorations or dental prosthesis by regular toothbrushing.

    Oral health care in pregnancy is often avoided and misunderstood by physicians, dentists, and patients. Evidence-based practice guidelines are still being developed. Research suggests that some prenatal oral conditions may have adverse consequences for the child. Periodontitis is associated with preterm birth and low birth weight, and high levels of cariogenic bacteria in mothers can lead to increased dental caries in the infant. Other oral lesions, such as gingivitis and pregnancy tumors, are benign and require only reassurance and monitoring. Every pregnant woman should be screened for oral risks, counseled on proper oral hygiene, and referred for dental treatment when necessary. Dental procedures such as diagnostic radiography, periodontal treatment, restorations, and extractions are safe and are best performed during the second trimester. Xylitol and chlorhexidine may be used as adjuvant therapy for high-risk mothers in the early postpartum period to reduce transmission of cariogenic bacteria to their infants. Appropriate dental care and prevention during pregnancy may reduce poor prenatal outcomes and decrease infant caries.

  12. Canine oral melanoma.

    Melanoma is the most common oral malignancy in the dog. Oral and/or mucosal melanoma has been routinely considered an extremely malignant tumor with a high degree of local invasiveness and high metastatic propensity. Primary tumor size has been found to be extremely prognostic. The World Health Organization staging scheme for dogs with oral melanoma is based on size, with stage I = or = 4cm tumor and/or lymph node metastasis, and stage IV = distant metastasis. Median survival times for dogs with oral melanoma treated with surgery are approximately 17 to 18, 5 to 6, and 3 months with stage I, II, and III disease, respectively. Significant negative prognostic factors include stage, size, evidence of metastasis, and a variety of histologic criteria. Standardized treatments such as surgery, coarse-fractionation radiation therapy, and chemotherapy have afforded minimal to modest stage-dependent clinical benefits and death is usually due to systemic metastasis. Numerous immunotherapeutic strategies have been employed to date with limited clinical efficacy; however, the use of xenogeneic DNA vaccines may represent a leap forward in clinical efficacy. Oral melanoma is a spontaneous syngeneic cancer occurring in outbred, immunocompetent dogs and appears to be a more clinically faithful therapeutic model for human melanoma; further use of canine melanoma as a therapeutic model for human melanoma is strongly encouraged. In addition, the development of an expanded but clinically relevant staging system incorporating the aforementioned prognostic factors is also strongly encouraged.

    2001-01-01

    Purpose: The use of oral chemotherapeutic agents in chemoradiotherapy provides several advantages. Doxifluridine, an oral 5-FU prodrug, has been shown to be effective in colorectal cancer. We attempted a Phase II trial of preoperative chemoradiotherapy with doxifluridine plus a low-dose oral leucovorin in unresectable primary rectal cancer patients. In this study, toxicity and efficacy were evaluated. Methods and Materials: There were 23 patients with primary unresectable rectal cancer in this trial, 21 of whom were available for analysis. The patients were treated with oral doxifluridine (900 mg/day) plus oral leucovorin (30 mg/day) from days 1 to 35, and pelvic radiation of 45 Gy over 5 weeks. Surgical resection was performed 5-6 weeks after the treatment. Results: Acute toxicity involved thrombocytopenia, nausea/vomiting, diarrhea, and skin reaction. All were in Grade 1/2, except diarrhea, which was not only the most frequent (7 patients, 33.3%), but also the only toxicity of Grade 3 (2 patients). The clinical tumor response was shown in 5 patients (23.8%) as a complete response and 13 patients (61.9%) as a partial response. A complete resection with negative resection margin was done in 18 patients (85.7%), in 2 of whom a pathologic complete response was shown (9.5%). The overall downstaging rate in the T- and N-stage groupings was 71.4% (15 patients). Conclusion: This study demonstrated the efficacy and low toxicity of chemoradiotherapy with doxifluridine. Currently, a Phase III randomized trial of chemoradiotherapy is ongoing at our institute to compare the therapeutic efficacy of oral 5-FU with respect to i.v. 5-FU in locally advanced and unresectable rectal cancer

    The closing submissions are presented on behalf of Greenpeace Ltd to a Planning Inquiry in 1995 hearing the application of UK Nirex Ltd for permission to construct an underground Rock Characterisation Facility (RCF) at a site near Sellafield. The RCF is part of an investigation by Nirex into a suitable site for the disposal of radioactive waste. Greenpeace conclude that the application should be refused on the following grounds: that it has not been demonstrated that the RCF will meet its stated purpose and that it is highly unlikely that it will ever sufficiently characterise the site for a Detailed Safety Assessment to be made; in the unlikely event that the RCF should achieve its purpose there can be no confidence that the approach of Nirex so far will lead to the greatest measure of radiological safety to the public; in the light of Nirex's failure so far to produce any reliable assessments of its investigation programme, it is not possible to determine what benefits, if any, could be gained from results from the RCF; alternative sites exist which appear to offer significantly better safety levels.

    Full Text Available Pyogenic granuloma is one of the inflammatory hyperplasias seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection and in reality arises in response to various stimuli such as low-grade local irritation, traumatic injury, or hormonal factors. It predominantly occurs in the second decade of life in young females, possibly because of the vascular effects of female hormones. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic lesion manifesting as small, red erythematous growth on a pedunculated or sometimes sessile base, which is usually hemorrhagic. Although excisional surgery is the treatment of choice , some other treatment protocols such as the use of Nd:YAG laser, flash lamp pulsed dye laser, cryosurgery, intralesional injection of ethanol or corticosteroids, and sodium tetradecyl sulfate sclerotherapy have been proposed. We present the case of a 25-year-old pregnant woman with large oral pyogenic granuloma.

    Acute otitis externa, also known as ‘swimmer’s ear’, is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

    2016-03-01

    Increased use of smartphone and related software applications has created a new era in clinical data exchange among patients and clinicians. This study describes use of the smartphone-based application WhatsApp to share clinical oral medicine information. Clinical images and related questions were submitted by general dentists, physicians, dental hygienists, and patients to the authors via WhatsApp. For each submission, a clinical impression was made and categorized as traumatic, infective, neoplastic, autoimmune, or unclassified. Submissions were summarized by sender type, number of photographs per sender, and category of question. Patients were invited to undergo a clinical examination with biopsy, when indicated. The telemedicine impression was compared to the clinicopathologic diagnosis. Three hundred and thirty-nine images were received for 96 patients; 92 (95.8%) patients underwent clinicopathologic examination, and 45 (49%) received a biopsy. General dentists (62%) and dental hygienists (26%) were the most frequent senders. The most common question was related to diagnosis (56%). The telemedicine impression agreed with the clinicopathologic assessment for 82% of cases. Telemedicine applications, such as WhatsApp, can support communication about oral conditions among clinicians and patients. Telemedicine consultation reduced geographic barriers to initial clinical consultation and encouraged the significant majority of patients to pursue expert clinical examination.

    Touger-Decker, Riva; Mobley, Connie

    2013-05-01

    It is the position of the Academy of Nutrition and Dietetics that nutrition is an integral component of oral health. The Academy supports integration of oral health with nutrition services, education, and research. Collaboration between dietetics practitioners and oral health care professionals is recommended for oral health promotion and disease prevention and intervention. Scientific and epidemiological data suggest a lifelong synergy between diet, nutrition, and integrity of the oral cavity in health and disease. Oral health and nutrition have a multifaceted relationship. Oral infectious diseases, as well as acute, chronic, and systemic diseases with oral manifestations, impact an individual's functional ability to eat and their nutrition status. Likewise, nutrition and diet can affect the development and integrity of the oral cavity and progression of oral diseases. As knowledge of the link between oral and nutrition health increases, dietetics practitioners and oral health care professionals must learn to provide screening, education, and referrals as part of comprehensive client/patient care. The provision of medical nutrition therapy, including oral and overall health, is incorporated into the Standards of Practice for registered dietitians and dietetic technicians, registered. Inclusion of didactic and clinical practice concepts that illustrate the role of nutrition in oral health is essential in education programs for both professional groups. Collaborative endeavors between dietetics, dentistry, medicine, and allied health professionals in research, education, and delineation of practice roles are needed to ensure comprehensive health care. The multifaceted interactions between diet, nutrition, and oral health in practice, education, and research in both dietetics and dentistry merit continued, detailed delineation.

    The treatment of oral cancer requires an effective rehabilitation strategy such as an early intensive rehabilitation (EIR) program. The medical records and data of 41 patients who participated in an EIR program and 20 control group patients were analyzed. These patients all underwent surgical resection of the primary tumor followed by microsurgical reconstruction using free flaps. The length of stay (LOS) at the acute care hospital was compared between the two groups. Four indexes were used to evaluate the effectiveness of the EIR program. EIR patients stayed an average of 11.6 fewer days at the acute care hospital. All indexes showed significant improvements (p < 0.001). The Barthel Index (BI) and the Early Intensive Rehabilitation Barthel Index (EIR-BI) improved by 36.0 and 103.6 points, respectively. At discharge, the Bogenhausener Dysphagia Score (BODS) had improved to a score of 11.0 compared to the 13.9 at admission. EIR patients had a Work Ability Index (WAI) score of 25.7. Length of stay at the acute care hospital can be reduced using early intensive rehabilitation if patients are transferred to an intensive rehabilitation clinic early.

    Oral health is affected by its resident microorganisms. Three prominent oral disorders are dental caries, gingivitis and periodontitis, with the oral microbiota playing a key role in the initiation/progression of all three. Understanding the microbiota and the diseases they may cause is critical to the development of new therapeutics. This review is focused on probiotics for the prevention and/or treatment of oral diseases. This review describes the oral ecosystem and its correlation with oral health/disease. The pathogenesis and current prevention/treatment strategies of periodontal diseases (PD) and dental caries (DC) are depicted. An introduction of probiotics is followed by an analysis of their role in PD and DC, and their potential role(s) in oral health. Finally, a discussion ensues on the future research directions and limitations of probiotics for oral health. An effective oral probiotic formulation should contribute to the prevention/treatment of microbial diseases of the oral cavity. Understanding the oral microbiota's role in oral disease is important for the development of a therapeutic to prevent/treat dental diseases. However, investigations into clinical efficacy, delivery/dose optimization, mechanism(s) of action and other related parameters are yet to be fully explored. Keeping this in mind, investigations into oral probiotic therapies are proving promising.
