    2015-12-01

    Full Text Available Objective:To compare efficacy and safety of primaquine regimens currently used to prevent relapses by P. vivax.Methods:A systematic review was carried out to identify clinical trials evaluating efficacy and safety to prevent malaria recurrences by P. vivax of primaquine regimen 0.5 mg / kg / day for 7 or 14 days compared to standard regimen of 0.25 mg/kg/day for 14 days. Efficacy of primaquine according to cumulative incidence of recurrences after 28 days was determined. The overall relative risk with fixed-effects meta-analysis was estimated.Results:For the regimen 0.5 mg/kg/day/7 days were identified 7 studies, which showed an incidence of recurrence between 0% and 20% with follow-up 60-210 days; only 4 studies comparing with the standard regimen 0.25 mg/kg/day/14 days and no difference in recurrences between both regimens (RR= 0.977, 95% CI= 0.670 to 1.423 were found. 3 clinical trials using regimen 0.5 mg/kg/day/14 days with an incidence of recurrences between 1.8% and 18.0% during 330-365 days were identified; only one study comparing with the standard regimen (RR= 0.846, 95% CI= 0.484 to 1.477. High risk of bias and differences in handling of included studies were found.Conclusion:Available evidence is insufficient to determine whether currently PQ regimens used as alternative rather than standard treatment have better efficacy and safety in preventing relapse of P. vivax. Clinical trials are required to guide changes in treatment regimen of malaria vivax.

    AIM- To compare the efficacy of a 7-d vs 10-d triple therapy regarding H pylori eradication, endoscopic findings and histological gastric inflammatory inactivation in the Ecuadorian population. METHODS: 136 patients with dyspepsia and H pylori infection were randomized in 2 groups (68 per group): group 1, 7-d therapy; group 2, t0-d therapy. Both groups received the same medication and daily dosage: omeprazole 20 mg bid, clarithromycin 500 mg bid and amoxicillin I g bid. Endoscopy was performed for histological assessment and H pylori infection status before and 8 wk after treatment. RESULTS: H pylori was eradicated in 68% of group 1 vs 83. 8% of group 2 for the intention-to-treat analysis (ITT) (P = 0. 03; OR = 2. 48; 95% CI, 1. 1-5. 8), and 68% in group 1 vs 88% in group 2 for the per-protocol analysis (PP) (P = 0. 008; OR = 3. 66; 95% CI, 1. 4-10). Endoscopic gastric mucosa normalization was observed in 56. 9% in group 1 vs 61. 2% in group 2 for ITT, with similar results for the PP, the difference being statistically not significant. The rate of inflammatory inactivation was 69% in group 1 vs 88. 7% in group 2 for ITT (P = 0. 007;OR = 3. 00; 95% CI, 1. 2-7. 5), and 69% in group 1 vs96% in group 2 for PP (P = 0. 0002; OR = 7. 25; 95% CI, 2-26). CONCLUSION: In this Ecuadorian population, the 10-d therapy was more effective than the 7-d therapy for H pylori eradication as well as for gastric mucosa inflammatory inactivation.

    2009-12-01

    The purpose of this paper was to compare the efficacy of a single dose of 3 g of fosfomycin to that of a 7-day regimen of amoxicillin-clavulanate in the treatment of asymptomatic bacteriuria during pregnancy. A randomised, prospective, interventional, analytical, longitudinal study was undertaken, in which the efficacy of two antibiotic regimens (one short and the other long) in the treatment of pregnant women with asymptomatic bacteriuria is compared. One hundred and nine patients were randomly assigned to two groups: 56 were treated with amoxicillin-clavulanate and 53 with fosfomycin. The two groups were similar in terms of co-morbidity, treatments received during pregnancy, obstetric, gynaecological and surgical history and laboratory data. The efficacy of the two regimens was similar and the eradication rate was over 80% in both groups (P = 0.720) (relative risk [RR] 1.195, 95% confidence interval [CI]: 0.451-3.165). The number of reinfections was greater in the amoxicillin-clavulanate group (P = 0.045). The secondary effects were lower in the fosfomycin group (P = 0.008). There were no significant differences in the number of persistences (P = 0.39), development of symptomatic urinary infections (P = 0.319) or recurrences (P = 0.96). Treatment with a single dose of fosfomycin is as effective as the standard course of treatment with amoxicillin-clavulanate and may be preferable due to its simpler administration and the smaller number of reinfections.

    2012-06-01

    Full Text Available Abstract Background Relapsing Plasmodium vivax infection results in significant morbidity for the individual and is a key factor in transmission. Primaquine remains the only licensed drug for prevention of relapse. To minimize relapse rates, treatment guidelines have recently been revised to recommend an increased primaquine dose, aiming to achieve a cumulative dose of ≥6 mg/kg, i.e. ≥420 mg in a 70 kg patient. The aims of this study were to characterize the epidemiology of P. vivax infection imported into Queensland Australia, to determine the rates of relapse, to investigate the use of primaquine therapy, and its efficacy in the prevention of relapse. Methods A retrospective study was undertaken of laboratory confirmed P. vivax infection presenting to the two major tertiary hospitals in Queensland, Australia between January 1999 and January 2011. Primaquine dosing was classified as no dose, low dose ( Results Twenty relapses occurred following 151 primary episodes of P. vivax infection (13.2%. Relapses were confirmed among 3/21 (14.2%, 9/50 (18.0%, 1/54 (1.9% and 7/18 (38.9% of patients administered no dose, low dose, high dose and unknown primaquine dose respectively. High dose primaquine therapy was associated with a significantly lower rate of relapse compared to patients who were prescribed low dose therapy (OR 11.6, 95% CI 1.5-519, p = 0.005. Conclusions Relapse of P. vivax infection is more likely in patients who received low dose primaquine therapy. This study supports the recommendations that high dose primaquine therapy is necessary to minimize relapse of P. vivax malaria.

  9. Primaquine pharmacology in the context of CYP 2D6 pharmacogenomics: Current state of the art.

    Marcsisin, Sean R; Reichard, Gregory; Pybus, Brandon S

    2016-05-01

    Primaquine is the only antimalarial drug available to clinicians for the treatment of relapsing forms of malaria. Primaquine development and usage dates back to the 1940s and has been administered to millions of individuals to treat and eliminate malaria infections. Primaquine therapy is not without disadvantages, however, as it can cause life threatening hemolysis in humans with glucose-6-phosphate dehydrogenase (G6PD) deficiency. In addition, the efficacy of primaquine against relapsing malaria was recently linked to CYP 2D6 mediated activation to an active metabolite, the structure of which has escaped definitive identification for over 75years. CYP 2D6 is highly polymorphic among various human populations adding further complexity to a comprehensive understanding of primaquine pharmacology. This review aims to discuss primaquine pharmacology in the context of state of the art understanding of CYP 2D6 mediated 8-aminoquinoline metabolic activation, and shed light on the current knowledge gaps of 8-aminoquinoline mechanistic understanding against relapsing malaria.

  11. Primaquine plus artemisinin combination therapy for reduction of malaria transmission: promise and risk.

    John, Chandy C

    2016-01-01

    Reduction of gametocyte transmission from humans to mosquitoes is a key component of malaria elimination. The study by Gonçalves and colleagues provides valuable new data on how the addition of low-dose primaquine to artemether-lumefantrine affects reduction of gametocytemia and transmission of gametocytes to mosquitoes in asymptomatically Plasmodium falciparum-infected children without G6PD deficiency, and on the degree to which low-dose primaquine affects hemoglobin levels in these children. The study sets the stage for future research required for consideration of an artemisinin combination therapy (ACT)-primaquine regimen in mass drug administration campaigns. Future studies will need to evaluate toxicity in adults and G6PD deficient persons, assess gametocyte transmission from adults, evaluate different ACT drugs with primaquine, and assess the implications of "rare" toxicities in large treatment populations, such as hemolysis requiring blood transfusion. The study highlights both the promise and the potential risk of ACT-primaquine treatment in malaria elimination campaigns.Please see related article: https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-016-0581-y .

  13. Optimising strategies for Plasmodium falciparum malaria elimination in Cambodia: primaquine, mass drug administration and artemisinin resistance.

    Richard J Maude

    Full Text Available BACKGROUND: Malaria elimination requires a variety of approaches individually optimized for different transmission settings. A recent field study in an area of low seasonal transmission in South West Cambodia demonstrated dramatic reductions in malaria parasite prevalence following both mass drug administration (MDA and high treatment coverage of symptomatic patients with artemisinin-piperaquine plus primaquine. This study employed multiple combined strategies and it was unclear what contribution each made to the reductions in malaria. METHOD AND FINDINGS: A mathematical model fitted to the trial results was used to assess the effects of the various components of these interventions, design optimal elimination strategies, and explore their interactions with artemisinin resistance, which has recently been discovered in Western Cambodia. The modelling indicated that most of the initial reduction of P. falciparum malaria resulted from MDA with artemisinin-piperaquine. The subsequent continued decline and near elimination resulted mainly from high coverage with artemisinin-piperaquine treatment. Both these strategies were more effective with the addition of primaquine. MDA with artemisinin combination therapy (ACT increased the proportion of artemisinin resistant infections, although much less than treatment of symptomatic cases with ACT, and this increase was slowed by adding primaquine. Artemisinin resistance reduced the effectiveness of interventions using ACT when the prevalence of resistance was very high. The main results were robust to assumptions about primaquine action, and immunity. CONCLUSIONS: The key messages of these modelling results for policy makers were: high coverage with ACT treatment can produce a long-term reduction in malaria whereas the impact of MDA is generally only short-term; primaquine enhances the effect of ACT in eliminating malaria and reduces the increase in proportion of artemisinin resistant infections; parasite

    Safe treatment of Plasmodium vivax requires diagnosis of both the infection and status of erythrocytic glucose-6-phosphate dehydrogenase (G6PD) activity because hypnozoitocidal therapy against relapse requires primaquine, which causes a mild to severe acute hemolytic anemia in G6PD deficient patients. Many national malaria control programs recommend primaquine therapy without G6PD screening but with monitoring due to a broad lack of G6PD deficiency screening capacity. The degree of risk in do...

    Diarrhea is the second leading cause of death in children under 5 years of age globally. The time patients and caregivers spend at a health facility for severe diarrhea presents the opportunity to deliver water, sanitation, and hygiene (WASH) interventions. We recently developed Cholera-Hospital-Based Intervention for 7 days (CHoBI7), a 1-week hospital-based handwashing with soap and water treatment intervention, for household members of cholera patients. To investigate if this intervention could lead to sustained WASH practices, we conducted a follow-up evaluation of 196 intervention household members and 205 control household members enrolled in a randomized controlled trial of the CHoBI7 intervention 6 to 12 months post-intervention. Compared with the control arm, the intervention arm had four times higher odds of household members' handwashing with soap at a key time during 5-hour structured observation (odds ratio [OR]: 4.71, 95% confidence interval [CI]: 2.61, 8.49) (18% versus 50%) and a 41% reduction in households in the World Health Organization very high-risk category for stored drinking water (OR: 0.38, 95% CI: 0.15, 0.96) (58% versus 34%) 6 to 12 months post-intervention. Furthemore, 71% of observed handwashing with soap events in the intervention arm involved the preparation and use of soapy water, which was promoted during the intervention, compared to 9% of control households. These findings demonstrate that the hospital-based CHoBI7 intervention can lead to significant increases in handwashing with soap practices and improved stored drinking water quality 6 to 12 months post-intervention.

  17. Cytochrome P450-dependent toxic effects of primaquine on human erythrocytes

    Primaquine, an 8-aminoquinoline, is the drug of choice for radical cure of relapsing malaria. Use of primaquine is limited due to its hemotoxicity, particularly in populations with glucose-6-phosphate dehydrogenase deficiency [G6PD(-)]. Biotransformation appears to be central to the anti-infective and hematological toxicities of primaquine, but the mechanisms are still not well understood. Metabolic studies with primaquine have been hampered due to the reactive nature of potential hemotoxic metabolites. An in vitro metabolism-linked hemotoxicity assay has been developed. Co-incubation of the drug with normal or G6PD(-) erythrocytes, microsomes or recombinant cytochrome P450 (CYP) isoforms has allowed in situ generation of potential hemotoxic metabolite(s), which interact with the erythrocytes to generate hemotoxicity. Methemoglobin formation, real-time generation of reactive oxygen intermediates (ROIs) and depletion of reactive thiols were monitored as multiple biochemical end points for hemotoxicity. Primaquine alone did not produce any hemotoxicity, while a robust increase was observed in methemoglobin formation and generation of ROIs by primaquine in the presence of human or mouse liver microsomes. Multiple CYP isoforms (CYP2E1, CYP2B6, CYP1A2, CYP2D6 and CYP3A4) variably contributed to the hemotoxicity of primaquine. This was further confirmed by significant inhibition of primaquine hemotoxicity by the selective CYP inhibitors, namely thiotepa (CYP2B6), fluoxetine (CYP2D6) and troleandomycin (CYP3A4). Primaquine caused similar methemoglobin formation in G6PD(-) and normal human erythrocytes. However, G6PD(-) erythrocytes suffered higher oxidative stress and depletion of thiols than normal erythrocytes due to primaquine toxicity. The results provide significant insights regarding CYP isoforms contributing to hemotoxicity and may be useful in controlling toxicity of primaquine to increase its therapeutic utility.

  19. Is primaquine useful and safe as true exo-erythrocytic merontocidal, hypnozoitocidal and gametocidal antimalarial drug?

    Francisco Javier López-Antuñano

    1999-10-01

    Full Text Available The main objective of this paper is to make available in a single document, a sequence of events that have been published on the biology of malaria parasites and their interaction with the human host, looking for arguments for effective and save treatment: what we know and what we would like to know about the effects of primaquine in order to justify its use in clinical and public health practice. The practicioner should be aware that the antimalarial activity, hemolytic and methemoglobinemic side effects, and detoxification of primaquine are all thought to depend on various biotransformation products of the drug. In spite of the universal use during over six decades, their site and mechanism of formation and degradation and their specific biologic effects remain very poorly understood in human beings. The mature gametocytes of P. falciparum are naturally resistant to chloroquine and other blood merontocides, but they are usually eliminated with a single dose of 1.315 mg/kg per os (p.o. of primaquine phosphate (equivalent to 0.75 mg-base. Rather than empirically, related with relapses frequency, dosage schedules should only be determined through consideration of the kinetics and dynamics of the drug and its effect on sporozoites, pre and exo-erythrocytic merontes, hypnozoites and gametocytes of P. vivax. Where medical care services are not available or not capable to detect glucose -6- phosphate dehydrogenese- (G-6-PD deficiencies and deleterious effects of the drug, we recommend not to use primaquine. Both, P. vivax primary clinical attack and P. vivax relapses, as and when they occur should be treated with a course of 10 mg/kg chloroquine-base p.o. Prevention of relapses is probably related to strain characteristics of P. vivax hypnozoites populations envolved. If well informed and qualified medical care workers decide to use primaquine in the absence of enzime defficiencies and are able to follow-up the clinical, toxicological and parasitic

  20. Rationale for recommending a lower dose of primaquine as a Plasmodium falciparum gametocytocide in populations where G6PD deficiency is common

    White Nicholas J

    2012-12-01

    Full Text Available Abstract In areas of low malaria transmission, it is currently recommended that a single dose of primaquine (0.75 mg base/kg; 45 mg adult dose be added to artemisinin combination treatment (ACT in acute falciparum malaria to block malaria transmission. Review of studies of transmission-blocking activity based on the infectivity of patients or volunteers to anopheline mosquitoes, and of haemolytic toxicity in glucose 6-dehydrogenase (G6PD deficient subjects, suggests that a lower primaquine dose (0.25 mg base/kg would be safer and equally effective. This lower dose could be deployed together with ACTs without G6PD testing wherever use of a specific gametocytocide is indicated.

    Full Text Available Fabrication and Evaluation of matrix type Transdermal Patches of Primaquine Phosphate with different ratio of eudragit-L100 and S-100 combination by the solvent evaporation technique. All the patches have been evaluated for their Physiochemical properties was studied by infrared Spectroscopy. Formulation F1 was found best among the all formulation on basis maximum in-vitro release, drug content and folding endurance i.e. 4.711, 99% ± 0.2, 26 ± 2. Other parameters like moisture content, moisture uptake, surface pH was found 1.32 ± 0.38, 3.14 ± 0.2 and 8.9 respectively. Hence F1 formulation was used to incorporate penetration enhancer labrafac™ PD, labrafil® 1944CS and lauroglucol™ FCC. By using this three penetration enhancer nine formulation L1 to L9 was fabricated to increasing volume of 0.5ml, 1.0ml, 1.5 ml. All the formulation was tested for thickness, weight variation, folding endurance, surface pH, moisture content and %drug content. L6 was showing maximum drug content and folding endurance as 99.8%, 28 respectively. The in-vitro release study was carried out with Shimadzu HPLC system. L6 formulation showed the best release value 75.47% in 24hr, emerging to be ideal formulations for Primaquine Phosphate and the mechanism of release was fitted to peppas kinetic models. The formulated transdermal patches increase antimalarial activity and reduced the adverse drug reactions gastrointestinal distress, nausea and methemoglobinemia with cyanosis.

  2. Rationale for short course primaquine in Africa to interrupt malaria transmission

    Eziefula Alice C

    2012-10-01

    Full Text Available Abstract Following the recent successes of malaria control in sub-Saharan Africa, the gametocytocidal drug primaquine needs evaluation as a tool to further reduce the transmission of Plasmodium falciparum malaria. The drug has scarcely been used in Africa because of concerns about its safety in people with glucose-6-phosphate dehydrogenase (G6PD deficiency. The evidence base for the use of primaquine as a transmission blocker is limited by a lack of comparable clinical and parasitological endpoints between trials. In March 2012, a group of experts met in London to discuss the existing evidence on the ability of primaquine to block malaria transmission, to define the roadblocks to the use of primaquine in Africa and to develop a roadmap to enable its rapid, safe and effective deployment. The output of this meeting is a strategic plan to optimize trial design to reach desired goals efficiently. The roadmap includes suggestions for a series of phase 1, 2, 3 and 4 studies to address specific hurdles to primaquine’s deployment. These include ex-vivo studies on efficacy, primaquine pharmacokinetics and pharmacodynamics and dose escalation studies for safety in high-risk groups. Phase 3 community trials are proposed, along with Phase 4 studies to evaluate safety, particularly in pregnancy, through pharmacovigilance in areas where primaquine is already deployed. In parallel, efforts need to be made to address issues in drug supply and regulation, to map G6PD deficiency and to support the evaluation of alternative gametocytocidal compounds.

    Full Text Available Aim A combination of PPI and 1000 mg amoxicillin/500 mg clarithromycin twice daily for 2 weeks has been proven effective in the eradication of H. pylori. Most studies suggested that treatment for 7 and 10 days may be equally effective. Few data are available on the efficacy of 5-day triple therapy. Aim of this study was to compare 5-day and 7-day rabeprazole triple therapy for eradication of H. pylori infection.Methods We prospectively studied 60 consecutive H. pylori-infected patients who came to hospitals in six centres in Indonesia and who underwent upper endoscopy and biopsy. H. pylori infection was confirmed if two rapid urease tests (Pronto Dry and histology or urea breath test were positive. Patients were assigned to either an open-labelled 5-day or 7-day course of oral amoxicillin 1000 mg b.i.d., clarithromycin 500 mg b.i.d., and rabeprazole 10 mg b.i.d. (RAC. Four weeks after therapy, all patients had a repeated UBT for evaluation of the presence of H. pylori.Results Of the 60 patients (42 males and 18 females with mean age (± SD 47.63 ± 13.93 years, range 21–74 years, 25 patients (41.7% had 5-day treatment and 35 patients (58.3% had 7-day treatment. With 5-day treatment, 18 patients (72% and with 7-day treatment 32 patients (91.4% became negative for H. pylori infection. The eradication failure was found on 7 patients (28.0% in 5-day treatment and 3 patients (8.6% in 7-day treatment.Conclusions The study showed that the eradication of H. pylori infection by triple rabeprazole-based treatment in 7-day is still better than in 5-day.

    2016-01-01

    Most cervical teratomas are benign. However, because of their location and size, these neoplasms cause airway obstruction, and the prognosis of patients is poor if left untreated. Early diagnosis by antenatal ultrasound, airway management, and a multidisciplinary team approach to treatment are therefore necessary. This report describes a 7-day-old male neonate who presented at our institution with a huge neck mass that was treated by surgical excision.

    To study the effects of microgravity on the skin microcirculatory function, basal blood flow and stimulated vasodilation were determined at the calf level by laser Doppler flowmetry in 8 male subjects before, during and after 7 days of dry immersion. Endothelium-dependent and - independent vasodilation was assessed using iontophoresis of acetylcholine and sodium nitroprusside, respectively. Basal blood flow was significantly reduced on the third day of immersion (13 ± 1 arbitrary units (AU) vs. 33 ± 8 AU pre-immersion level, p Endothelium dependent vasodilation was significantly decreased on the seventh day of immersion in comparison with pre-immersion values (12 ± 6% vs. 29 ± 6% of max vasodilation, p < 0.05). Our results support the idea that dry immersion induces changes in skin microcirculation with impairment of endothelial functions. Microcirculatory impairment should be considered as an important factor of the cardiovascular deconditioning.

  10. Spectrophotometric determination of primaquine by coupling with diazotized p-nitroaniline application to pharmaceutical formulations

    A simple spectrophotometric method for the determination of primaquine phosphate has been developed. The method is based on the coupling reaction of primaquine phosphate in acidic medium with diazotized p-nitroaniline, to form a yellow-orange water-soluble azo dye that shows maximum absorption at 482 nm. Beer's law is obeyed over the concentration range 5-300 macro g of primaquine phosphate in a final volume of 25 ml, i.e., 0.2-12 ppm with a molar absorptivity of 6.6 X 10/sup 4/ l mol/sup -1/ cm/sup -1/ and Sandell's sensitivity index of 0.0068 mu g.cm/sup -2/, a relative error of -0.63 to +0.32% and a relative standard deviation of +-0.18 to +- 2.8%, depending on the concentration level. Interferences due to excipients have been examined. The proposed method has been applied to the assay of primaquine phosphate in pharmaceutical formulations (tablets). (author)

  11. Impairment of IFN-gamma response to synthetic peptides of Mycobacterium tuberculosis in a 7-day whole blood assay.

    Hannah Priyadarshini Gideon

    Full Text Available Studies on Mycobacterium tuberculosis (MTB antigens are of interest in order to improve vaccine efficacy and to define biomarkers for diagnosis and treatment monitoring. The methodologies used for these investigations differ greatly between laboratories and discordant results are common. The IFN-gamma response to two well characterized MTB antigens ESAT-6 and CFP-10, in the form of recombinant proteins and synthetic peptides, was evaluated in HIV-1 uninfected persons in both long-term (7 day and 24 hour, commercially available QuantiFERON TB Gold in Tube (QFT-GIT, whole blood assays. Our findings showed differences in the IFN-gamma response between 24 hour and 7 day cultures, with recombinant proteins inducing a significantly higher response than the peptide pools in 7 day whole blood assays. The activity of peptides and recombinant proteins did not differ in 24 hour whole blood or peripheral blood mononuclear cell (PBMC based assays, nor in the ELISpot assay. Further analysis by SELDI-TOF mass spectrometry showed that the peptides are degraded over the course of 7 days of incubation in whole blood whilst the recombinant proteins remain intact. This study therefore demonstrates that screening antigenic candidates as synthetic peptides in long-term whole blood assays may underestimate immunogenicity.

  12. Comparative efficacy of 3-day and 7-day chemotherapy with twice-daily pivmecillinam in urinary tract infections seen in general practice.

    Richards, H H

    1984-01-01

    In a multi-centre general practice study, 183 females suffering from symptoms of acute urinary tract infection were randomly assigned to receive 400 mg pivmecillinam twice-daily for either 3 or 7 days. The clinical response was equally good in both treatment groups with a mean reduction in symptom scores of 88%. Positive pre-treatment bacteriological cultures were obtained from 48 (36%) of the 134 patients for whom data were complete. Bacteriological cure was achieved in all these patients except for 1 in the 3-day treatment group. Pivmecillinam was well tolerated, with side-effects reported by 7 (7%) patients in the 3-day group and 12 (13%) patients in the 7-day group. One patient in the 3-day group and 2 patients in the 7-day group stopped treatment prematurely due to side-effects. PMID:6499513

    We used quantum mechanics/molecular mechanics calculations to test if antimalarial primaquine (PQ) and its derivatives aid the conversion of hemoglobin to methemoglobin by binding to hemoglobin and merely lowering hemoglobin’s ionization potential (IP). Our results showed that PQ and its derivatives do not significantly lower the hemoglobin IP, disproving the hypothesis.

    2011-01-01

    Full Text Available Background and Aim: Platelets are routinely isolated from whole blood and stored in plasma for 5 days. The present study was done to assess the in vitro function of random donor platelets stored for 7 days in composol platelet additive solution at 22°C. Materials and Methods: The study sample included 30 blood donors of both sex in State Blood Bank, CSM Medical University, Lucknow. Random donor platelets were prepared by platelet rich plasma method. Whole blood (350 ml was collected in anticoagulant Citrate Phosphate Dextrose Adenine triple blood bags. Random donor platelets were stored for 7 days at 22°C in platelet incubators and agitators, with and without additive solution. Results: Platelet swirling was present in all the units at 22°C on day 7, with no evidence of bacterial contamination. Comparison of the mean values of platelet count, platelet factor 3, lactate dehydrogenase, pH, glucose and platelet aggregation showed no significant difference in additive solution, whereas platelet factor 3, glucose and platelet aggregation showed significant difference (P < 0.001 on day 7 without additive solution at 22°C. Conclusion: Our study infers that platelet viability and aggregation were best maintained within normal levels on day 7 of storage in platelet additive solution at 22°C. Thus, we may conclude that in vitro storage of random donor platelets with an extended shelf life of 7 days using platelet additive solution may be advocated to improve the inventory of platelets.

    Changes in skeletal muscle strength occur in response to chronic disuse or insufficient functional loading. The purpose of this study was to examine changes in muscle performance of the lower extremity and torso prior to and immediately after 7 days of simulated weightlessness (horizontal bed rest). A Biodex was used to determine concentric and eccentric peak torque and angle at peak torque for the back, abdomen, quadriceps, hamstring, soleus, and tibialis anterior. A reference angle of 0 degrees was set at full extension. Data were analyzed by ANOVA.

  1. Efficacy and safety of single and double doses of ivermectin versus 7-day high dose albendazole for chronic strongyloidiasis.

    Yupin Suputtamongkol

    Full Text Available BACKGROUND: Strongyloidiasis, caused by an intestinal helminth Strongyloides stercoralis, is common throughout the tropics. It remains an important health problem due to autoinfection, which may result in hyperinfection and disseminated infection in immunosuppressed patients, especially patients receiving chemotherapy or corticosteroid treatment. Ivermectin and albendazole are effective against strongyloidiasis. However, the efficacy and the most effective dosing regimen are to be determined. METHODS: A prospective, randomized, open study was conducted in which a 7-day course of oral albendazole 800 mg daily was compared with a single dose (200 microgram/kilogram body weight, or double doses, given 2 weeks apart, of ivermectin in Thai patients with chronic strongyloidiasis. Patients were followed-up with 2 weeks after initiation of treatment, then 1 month, 3 months, 6 months, 9 months, and 1 year after treatment. Combination of direct microscopic examination of fecal smear, formol-ether concentration method, and modified Koga agar plate culture were used to detect strongyloides larvae in two consecutive fecal samples in each follow-up visit. The primary endpoint was clearance of strongyloides larvae from feces after treatment and at one year follow-up. RESULTS: Ninety patients were included in the analysis (30, 31 and 29 patients in albendazole, single dose, and double doses ivermectin group, respectively. All except one patient in this study had at least one concomitant disease. Diabetes mellitus, systemic lupus erythrematosus, nephrotic syndrome, hematologic malignancy, solid tumor and human immunodeficiency virus infection were common concomitant diseases in these patients. The median (range duration of follow-up were 19 (2-76 weeks in albendazole group, 39 (2-74 weeks in single dose ivermectin group, and 26 (2-74 weeks in double doses ivermectin group. Parasitological cure rate were 63.3%, 96.8% and 93.1% in albendazole, single dose oral

    The aim of this study was to characterize changes of serum proteome profile during 7-day "dry" immersion (DI). The experiment with DI consisted of three series: control group without countermeasures (10 men), with using mechanical stimulation (6 men) and low-frequency myostimulation (5 men) as preventive means. Serum samples were fractionated using ClinProt robot (Bruker Daltonics) on magnetic beads (weak cation exchange magnetic beads—MB WCX) prior to mass-spectral profiling. It was obtained 170 peaks after fractionation of serum samples in each group. On 7th immersion day peak areas of fibrinopeptide A ( m/ z=1206; 1464), angiotensin II ( m/ z=1051), high molecular mass kininogen fragment ( m/ z=2133 Da) and C3-fragment of the complement system ( m/ z=1350 Da) were significantly decreased comparing with pre-experimental values of all experimental series. Peak areas of apolipoprotein C III ( m/ z=9419) and C4a fragment of the complement system ( m/ z=3206 Da) were increased. On 7th day of the recovery peak areas of all changed peaks were not close to pre-experimental values. This fact provided evidence of incomplete recovery of an organism after DI. The depth of the alterations had considerable individual variability. Thereby the detected changes of serum proteome profile in the experiment. They indicated a reorganization of the hormonal, immune systems and lipid metabolism. The use of myostimulation and mechanical stimulation as countermeasures partly compensated adverse effects of 7-day dry immersion on the parameters of coagulation system (fibrinopeptide A) and lipid metabolism (apolipoprotein CIII).

  3. The time course of altered brain activity during 7-day simulated microgravity

    2015-05-01

    Full Text Available Microgravity causes multiple changes in physical and mental levels in humans, which can induce performance deficiency among astronauts. Studying the variations in brain activity that occur during microgravity would help astronauts to deal with these changes. In the current study, resting-state functional magnetic resonance imaging (rs-fMRI was used to observe the variations in brain activity during a 7-day head down tilt (HDT bed rest, which is a common and reliable model for simulated microgravity. The amplitudes of low frequency fluctuation (ALFF of twenty subjects were recorded pre-head down tilt (pre-HDT, during a bed rest period (HDT0, and then each day in the HDT period (HDT1–HDT7. One-way analysis of variance of the ALFF values over these 8 days was used to test the variation across time period (P<0.05, corrected. Compared to HDT0, subjects presented lower ALFF values in the posterior cingulate cortex and higher ALFF values in the anterior cingulate cortex during the HDT period, which may partially account for the lack of cognitive flexibility and alterations in autonomic nervous system seen among astronauts in microgravity. Additionally, the observed improvement in function in CPL during the HDT period may play a compensatory role to the functional decline in the paracentral lobule to sustain normal levels of fine motor control for astronauts in a microgravity environment. Above all, those floating brain activities during 7 days of simulated microgravity may indicate that the brain self-adapts to help astronauts adjust to the multiple negative stressors encountered in a microgravity environment.

PQ use in higher doses is limited by severe tissue toxicity including hematological- and gastrointestinal-related side effects. Nanoformulation of drugs in an appropriate drug carrier system has been extensively studied and shown to have the potential to improve bioavailability, thereby enhancing activity, reducing dose frequency, and subsequently reducing toxicity. The aim of this work was to design, synthesize, and characterize PQ-loaded solid lipid nanoparticles (SLNs (PQ-SLNs as a potential drug-delivery system. SLNs were prepared by a modified solvent emulsification evaporation method based on a water-in-oil-in-water (w/o/w double emulsion. The mean particle size, zeta potential, drug loading, and encapsulation efficiency of the PQ-SLNs were 236 nm, +23 mV, 14%, and 75%, respectively. The zeta potential of the SLNs changed dramatically, from -6.54 mV to +23.0 mV, by binding positively charged chitosan as surface modifier. A spherical morphology of PQ-SLNs was seen by scanning electron microscope. In vitro, release profile depicted a steady drug release over 72 hours. Differential scanning calorimeter thermograms demonstrated presence

  5. Continuous accelerated 7-days-a-week radiotherapy for head-and-neck cancer: Long-term results of Phase III clinical trial

    Purpose: To update 5-year results of a previously published study on special 7-days-a-week fractionation continuous accelerated irradiation (CAIR) for head-and-neck cancer patients. Methods and Materials: One hundred patients with squamous cell carcinoma of head and neck in Stage T2-4N0-1M were randomized between two definitive radiation treatments: accelerated fractionation 7 days a week including weekends (CAIR) and conventional 5 days a week (control). Hence the overall treatment time was 2 weeks shorter in CAIR. Results: Five-year local tumor control was 75% in the CAIR group and 33% in the control arm (p < 0.00004). Tumor-cure benefit corresponded with significant improvement in disease-free survival and overall survival rates. Confluent mucositis was the main acute toxicity, with the incidence significantly higher in CAIR patients than in control (respectively, 94% vs. 53%). When 2.0-Gy fractions were used, radiation necrosis developed in 5 patients (22%) in the CAIR group as a consequential late effect (CLE), but when fraction size was reduced to 1.8 Gy no more CLE occurred. Actuarial 5-year morbidity-free survival rate was similar for both treatments. Conclusions: Selected head-and-neck cancer patients could be treated very effectively with 7-days-a-week radiation schedule with no compromise of total dose and with slight 10% reduction of fraction dose (2 Gy-1.8 Gy), which article gives 1 week reduction of overall treatment time compared with standard 70 Gy in 35 fractions over 47-49 days. Although this report is based on the relatively small group of patients, its results have encouraged us to use CAIR fractionation in a standard radiation treatment for moderately advanced head-and-neck cancer patients

  6. Pyruvate ingestion for 7 days does not improve aerobic performance in well-trained individuals

    Morrison, M. A.; Spriet, L. L.; Dyck, D. J.

    2000-01-01

    The purposes of the present studies were to test the hypotheses that lower dosages of oral pyruvate ingestion would increase blood pyruvate concentration and that the ingestion of a commonly recommended dosage of pyruvate (7 g) for 7 days would enhance performance during intense aerobic exercise in well-trained individuals. Nine recreationally active subjects (8 women, 1 man) consumed 7, 15, and 25 g of pyruvate and were monitored for a 4-h period to determine whether blood metabolites were altered. Pyruvate consumption failed to significantly elevate blood pyruvate, and it had no effect on indexes of carbohydrate (blood glucose, lactate) or lipid metabolism (blood glycerol, plasma free fatty acids). As a follow-up, we administered 7 g/day of either placebo or pyruvate, for a 1-wk period to seven, well-trained male cyclists (maximal oxygen consumption, 62.3 +/- 3.0 ml. kg(-1). min(-1)) in a randomized, double-blind, crossover trial. Subjects cycled at 74-80% of their maximal oxygen consumption until exhaustion. There was no difference in performance times between the two trials (placebo, 91 +/- 9 min; pyruvate, 88 +/- 8 min). Measured blood parameters (insulin, peptide C, glucose, lactate, glycerol, free fatty acids) were also unaffected. Our results indicate that oral pyruvate supplementation does not increase blood pyruvate content and does not enhance performance during intense exercise in well-trained cyclists.

  9. Activation of K+ channels and Na+/K+ ATPase prevents aortic endothelial dysfunction in 7-day lead-treated rats

    Seven day exposure to a low concentration of lead acetate increases nitric oxide bioavailability suggesting a putative role of K+ channels affecting vascular reactivity. This could be an adaptive mechanism at the initial stages of toxicity from lead exposure due to oxidative stress. We evaluated whether lead alters the participation of K+ channels and Na+/K+-ATPase (NKA) on vascular function. Wistar rats were treated with lead (1st dose 4 μg/100 g, subsequent doses 0.05 μg/100 g, im, 7 days) or vehicle. Lead treatment reduced the contractile response of aortic rings to phenylephrine (PHE) without changing the vasodilator response to acetylcholine (ACh) or sodium nitroprusside (SNP). Furthermore, this treatment increased basal O2− production, and apocynin (0.3 μM), superoxide dismutase (150 U/mL) and catalase (1000 U/mL) reduced the response to PHE only in the treated group. Lead also increased aortic functional NKA activity evaluated by K+-induced relaxation curves. Ouabain (100 μM) plus L-NAME (100 μM), aminoguanidine (50 μM) or tetraethylammonium (TEA, 2 mM) reduced the K+-induced relaxation only in lead-treated rats. When aortic rings were precontracted with KCl (60 mM/L) or preincubated with TEA (2 mM), 4-aminopyridine (4-AP, 5 mM), iberiotoxin (IbTX, 30 nM), apamin (0.5 μM) or charybdotoxin (0.1 μM), the ACh-induced relaxation was more reduced in the lead-treated rats. Additionally, 4-AP and IbTX reduced the relaxation elicited by SNP more in the lead-treated rats. Results suggest that lead treatment promoted NKA and K+ channels activation and these effects might contribute to the preservation of aortic endothelial function against oxidative stress. -- Highlights: ► Increased free radicals production ► Increased Na+/K+ ATPase activity ► Promotes activation of the K+ channels and reduced vascular reactivity ► These effects preserve endothelial function against oxidative stress. ► Low concentrations constitute environmental cardiovascular

  12. Continuous 7-Days-A-Week External Beam Irradiation in Locally Advanced Cervical Cancer: Final Results of the Phase I/II Study

    Purpose: To evaluate the feasibility and efficacy of definitive continuous 7-days-a-week pelvic irradiation without breaks between external beam radiotherapy and brachytherapy in locally advanced cervical cancer. Methods and Materials: Between November 1998 and December 1999, 30 patients with International Federation of Obstetrics and Gynecology Stage IIB or IIIB cervical cancer were included in a prospective Phase I/II study of continuous 7-days-a-week pelvic irradiation, to the total Manchester point B dose of 40.0–57.6 Gy. The first 13 patients (Group A) were given a daily tumor dose of 1.6 Gy, and the remaining 17 patients (Group B) were given 1.8 Gy. One or two immediate brachytherapy applications (point A dose 10–20 Gy, each) were performed in 28 cases. Results: Two patients did not complete the irradiation because of apparent early progression of disease during the irradiation. Eleven of the 28 evaluable patients (39%; 45% and 35% in Groups A and B, respectively) completed their treatment within the prescribed overall treatment time. Acute toxicity (including severe European Organisation for Research and Treatment of Cancer/Radiation Therapy Oncology Group Grade 3 and 4 effects in 40%) was experienced by 83% of patients and resulted in unplanned treatment interruptions in 40% of all patients (31% and 47% of patients in Groups A and B, respectively). Severe intestinal side effects occurred in 31% and 41% of Patients in Groups A and B, respectively (p = 0.71). The 5-year overall survival probability was 33%. Cancer recurrence occurred in 63% of patients: 20% inside and 57% outside the pelvis. Cumulative incidence of late severe bowel and urinary bladder toxicity at 24 months was 15%. Conclusion: Continuous irradiation in locally advanced cervical cancer is associated with a high incidence of severe acute toxicity, resulting in unplanned treatment interruptions. Late severe effects and survival after continuous radiotherapy do not substantially differ from

  14. In Vitro Activities of Primaquine-Schizonticide Combinations on Asexual Blood Stages and Gametocytes of Plasmodium falciparum.

    Cabrera, Mynthia; Cui, Liwang

    2015-12-01

    Currently, the World Health Organization recommends addition of a 0.25-mg base/kg single dose of primaquine (PQ) to artemisinin combination therapies (ACTs) for Plasmodium falciparum malaria as a gametocytocidal agent for reducing transmission. Here, we investigated the potential interactions of PQ with the long-lasting components of the ACT drugs for eliminating the asexual blood stages and gametocytes of in vitro-cultured P. falciparum strains. Using the SYBR green I assay for asexual parasites and a flow cytometry-based assay for gametocytes, we determined the interactions of PQ with the schizonticides chloroquine, mefloquine, piperaquine, lumefantrine, and naphthoquine. With the sums of fractional inhibitory concentrations and isobolograms, we were able to determine mostly synergistic interactions for the various PQ and schizonticide combinations on the blood stages of P. falciparum laboratory strains. The synergism in inhibiting asexual stages and gametocytes was highly evident with PQ-naphthoquine, whereas synergism was moderate for the PQ-piperaquine, PQ-chloroquine, and PQ-mefloquine combinations. We have detected potentially antagonistic interactions between PQ and lumefantrine under certain drug combination ratios, suggesting that precautions might be needed when PQ is added as the gametocytocide to the artemether-lumefantrine ACT (Coartem).

  15. Randomized clinical trial on 7-day continuous accelerated irradiation (CAIR) of head and neck cancer - report on 3-year tumour control and normal tissue toxicity

    The purpose of the study was to evaluate tumour and normal tissues 3-year response to 7-day-a-week continuous accelerated irradiation (CAIR) compared to a conventional treatment (5 days per week) in a randomized trial. One hundred patients with squamous cell carcinoma of the head and neck in stage T2-4-N0-1M0 were entered into the trial between December 1, 1993 and June 30, 1996. Dose per fraction of 2.0 Gy (to the end of 1994), and 1.8 Gy (since January 1, 1995) was the same in both arms and delivered once a day at regular 24-h intervals to total dose in the range of 66-72 Gy (depending on tumour stage). The only difference was overall treatment time being 5 weeks in the CAIR and 7 weeks in control arm. Actuarial 3-year local tumour control was 82% in the CAIR and 37% in the control group (P < 0.0001) with reduction in local recurrence rate of 83%. Actuarial 3-year overall survival was 78 and 32% (P < 0.0001), respectively. Confluent mucositis was significantly more severe and lasted longer in the CAIR than in control arm. After 2.0 Gy fractions five of 23 patients (22%) in the CAIR developed early necroses over a period of 2-4 months of follow-up which can be considered as a consequential to severe protracted acute mucosal reactions (CLE). For this reason dose per fraction was lowered to 1.8 Gy and the CLE was not observed again until now. Thus the overall rate of CLE decreased to 10%. The gain in tumour control is likely the effect of shortening of overall treatment time by 14 days and regular continuous dose delivery during the whole course of radiation therapy including weekends. A 7-day schedule produces more severe acute mucosal reactions lasting longer than in conventional fractionation, however tolerable by patients. Relatively high rate (22%) of CLE in the 7-day arm observed during the first year of the study was eliminated by decreasing dose per fraction from 2.0 Gy to 1.8 Gy

Eight-year-old boys (n = 57) received 1 of 4 milk drinks: whey protein with low or high content of minerals, or casein protein with low or high content of minerals. The amount...... significantly affected by the treatments (P <.05). There was a significant interaction between milk-derived proteins and minerals with regard to sOC (P = .01). The intake of milk drinks containing whey increased sOC at the low content of minerals, whereas it decreased sOC at the high content of minerals (P <.05......). In contrast, milk drinks containing casein increased sOC both at the low and at the high contents of minerals. In conclusion, whey and casein (corresponding to their content in 1.5 L of milk) differently affect sOC in 8-year-old boys depending on the content of milk minerals, but do not seem to...

Long time it wasthought that adult mammalian central nervous system doesn't possess any or fewregenerative capacity. Nowadays it was demonstrated that also in the brain thereare stem cells which have the capacity to differentiate into astocytes,oligodendrocytes and neurons.In few degenerative diseases the stem cells lose the regenerative capacity withconsequences in diminishing and loss of functional capacity. Stem cell therapyrepresents a novel and promising therapeutic approach to treatment of a variety ofdegenerative disease as multiple sclerosis. For this it is necessary that a efficientstem cell source can be found and secondary to be proven that these transplantablecells have differential potential into neural tissue.In order to be able to possess a stem cell source capable to build an implant it isnecessary to know the cultivation technology and also the instruments to prove theircapacity to differentiate into specific cells of the nervous system. These were themotives that enabled us to to try to harvest, cultivate and differentiate stem cellsfrom the murine central nervous system.

    Ketamine has been reported to cause neonatal neurotoxicity via a neuronal apoptosis mechanism; however, no in vivo research has reported whether ketamine could affect postnatal neurogenesis in the hippocampal dentate gyrus (DG). A growing number of experiments suggest that postnatal hippocampal neurogenesis is the foundation of maintaining normal hippocampus function into adulthood. Therefore, this study investigated the effect of ketamine on hippocampal neurogenesis. Male Sprague-Dawley rats were divided into two groups: the control group (equal volume of normal saline), and the ketamine-anesthesia group (40 mg/kg ketamine in four injections at 1 h intervals). The S-phase marker 5-bromodeoxyuridine (BrdU) was administered after ketamine exposure to postnatal day 7 (PND-7) rats, and the neurogenesis in the hippocampal DG was assessed using single- or double-immunofluorescence staining. The expression of GFAP in the hippocampal DG was measured by western blot analysis. Spatial reference memory was tested by Morris water maze at 2 months after PND-7 rats exposed to ketamine treatment. The present results showed that neonatal ketamine exposure significantly inhibited neural stem cell (NSC) proliferation, decreased astrocytic differentiation, and markedly enhanced neuronal differentiation. The disruptive effect of ketamine on the proliferation and differentiation of NSCs lasted at least 1 week and disappeared by 2 weeks after ketamine exposure. Moreover, the migration of newborn neurons in the granule cell layer and the growth of astrocytes in the hippocampal DG were inhibited by ketamine on PND-37 and PND-44. Finally, ketamine caused a deficit in hippocampal-dependent spatial reference memory tasks at 2 months old. Our results suggested that ketamine may interfere with hippocampal neurogenesis and long-term neurocognitive function in PND-7 rats. These findings may provide a new perspective to explain the adult neurocognitive dysfunction induced by neonatal

    Purpose: Preoperative chemoradiation therapy (CRT) significantly decreases local recurrence in locally advanced rectal cancer. Various biomarkers in biopsy specimens obtained before CRT have been proposed as predictors of response. However, reliable biomarkers remain to be established. Methods and Materials: The study group comprised 101 consecutive patients with locally advanced rectal cancer who received preoperative CRT with oral uracil/tegafur (UFT) or S-1. We evaluated histologic findings on hematoxylin and eosin (H and E) staining and immunohistochemical expressions of Ki67, p53, p21, and apoptosis in biopsy specimens obtained before CRT and 7 days after starting CRT. These findings were contrasted with the histologic response and the degree of tumor shrinkage. Results: In biopsy specimens obtained before CRT, histologic marked regression according to the Japanese Classification of Colorectal Carcinoma (JCCC) criteria and the degree of tumor shrinkage on barium enema examination (BE) were significantly greater in patients with p21-positive tumors than in those with p21-negative tumors (P=.04 and P<.01, respectively). In biopsy specimens obtained 7 days after starting CRT, pathologic complete response, histologic marked regression according to both the tumor regression criteria and JCCC criteria, and T downstaging were significantly greater in patients with apoptosis-positive and p21-positive tumors than in those with apoptosis-negative (P<.01, P=.02, P=.01, and P<.01, respectively) or p21-negative tumors (P=.03, P<.01, P<.01, and P=.02, respectively). The degree of tumor shrinkage on both BE as well as MRI was significantly greater in patients with apoptosis-positive and with p21-positive tumors than in those with apoptosis-negative or p21-negative tumors, respectively. Histologic changes in H and E-stained biopsy specimens 7 days after starting CRT significantly correlated with pathologic complete response and marked regression on both JCCC and tumor

    In agricultural catchments, aquatic ecosystems can experience a pulse exposure to pesticides. Following such exposure, non-target organisms that are not extirpated may recover. This paper investigates the potential of two duckweed species (Lemna minor and Lemna gibba) to recover from a 7-day exposure to different concentrations (0.4-208 µg L(-1)) of the herbicide diuron. There was significant inhibition in the growth and biomass after the initial 7-day exposure (e.g. frond number EC50=59.2 and 52.2 µg L(-1) for L. minor and L. gibba, respectively). Following transfer to clean media, recovery (the highest concentration yielding no significant difference in the effect endpoint from the control) was observed for all effects endpoints at concentrations ranging 60-111 µg L(-1) for L. minor and 60-208 µg L(-1) for L. gibba. These results suggest that recovery is possible for primary producers at environmentally relevant concentrations considered significant in ecological risk assessment. PMID:26067703

    Endocrine regulation of fluids and electrolytes during 7 days of -6 degrees head-down bed rest (HDBR) was compared in male (n = 8) and, for the first time, female (n = 8) volunteers. The subjects' responses to quiet standing for 2 h before and after HDBR were also tested. In both sexes, diuresis and natriuresis were evident during the first 2-3 days of HDBR, resulting in a marked increase in the urinary Na(+)-to-K+ ratio and significant Na+ retention on re-ambulation. After the 1st day of HDBR, plasma renin activity (PRA) was increased relative to aldosterone (Aldo), plasma volume was decreased, and the renal response to Aldo appeared to be appropriate. Circulating levels of arginine vasopressin, cortisol, and ACTH were unchanged during HDBR. Plasma testosterone decreased slightly on day 2 of HDBR in males. The ratio of early morning ACTH to cortisol was lower in females than in males because ACTH was lower in females. Urinary cortisol increased and remained elevated throughout the HDBR in males only. There were no gender differences in the responses to 7 days of HDBR, except those in the pituitary-adrenal system; those differences appeared unrelated to the postural change. The provocative cardiovascular test of quiet standing before and after HDBR revealed both sex differences and effects of HDBR. There were significant sex differences in cardiovascular responses to standing before and after HDBR. Females had greater PRA and Aldo responses to standing before HDBR and larger Aldo responses to standing after HDBR than males.(ABSTRACT TRUNCATED AT 250 WORDS).

    Full Text Available AIM: Retrospective study of early (0-7 days outcome of babies born after ART (Assisted Reproductive Technology In vitro fertilization (IVF is the fertilization of a woman’s egg and a man’s sperm in a laboratory dish. In vitro means “outside the body.” Fertilization means the sperm has attached to and entered the egg. IVF is a form of assisted reproductive technology (ART. This means special medical techniques are used to help a woman become pregnant. There are five basic steps to IVF- Step 1: Stimulation, also called super ovulation, Step 2: Egg retrieval, Step 3: Insemination and Fertilization, Step 4: Embryo culture, Step 5: Embryo transfer. OBJECTIVE: To study the early (0-7 days outcome of babies born after ART (Assisted Reproductive Technology METHODS: This is a retrospective study conducted in Department of Pediatrics, Mahatma Gandhi Medical College & Hospital, Jaipur between Jan 2009- Jan 2010. Inclusion criteria consists of all IVF babies born at Mahatma Gandhi Medical College & Hospital, Jaipur and exclusion criteria consists of all out born babies and IVF babies delivered at another center. CONCLUSION: There were 54.28% male and 45.72% female babies. Most of the babies were above 1.5 kg (44.28% NBW +45.71% LBW= 89.99%. There were only 5.71% babies born before 32 weeks of gestation. 61.42% were Singleton. Complication rate was low with Respiratory Distress in 10 babies, Sepsis in 4 babies and Jaundice in 22. All were treated successfully. There was no mortality.

  3. Molecular modeling of the voltammetric oxidation at a glassy carbon electrode of the antimalarial drug primaquine and its prodrugs succinylprimaquine and maleylprimaquine

    The 8-aminoquinoline primaquine (PQ) is the only antimalarial drug used as tissue schizonticide and relapsing malaria. Antichagasic activity was also reported. Nevertheless, as it also shows serious side effects, prodrugs such as succinyl and maleyl derivatives have been proposed to decrease its toxicity. Although PQ mechanism of action has not been completely elucidated, the promotion of oxidative stress is an advanced hypothesis that could explain its activity in both plasmodia and trypanosome parasites. The oxidation of PQ and its prodrugs, maleylprimaquine (MPQ) and succinylprimaquine (SPQ), was studied by cyclic voltammetry using glassy carbon electrode. All compounds were oxidized in aqueous medium, with the charge transfer process being pH-dependent in acidic medium and pH-independent in a weak basic medium, being the neutral form more easily oxidized. This indicated that the protonation of the nitrogen atoms displays a determinant role in the voltammetric oxidation, being both prodrugs more easily oxidized than PQ protonated forms, in the order: SPQ < MPQ < PQ. For a better understanding of this behavior, a molecular modeling study was performed using the AM1 semi-empirical method from Spartan 04 for Linux (v.119, Wavefunction Inc.). The medium pH showed to be fundamental not only to the electronic density of the quinoline ring but also to the rearrangement of the nitrogen side chain. The electronic density of primaquine non-protonated quinoline ring is higher than that in its protonated and diprotonated species. Also, the use of prodrugs and the degree of saturation of the carriers (maleic or succinic acid) interfere with this feature. SPQ and MPQ have a slight increase in the quinoline electronic density in comparison to PQ. Nevertheless, the carrier in the side chain of SPQ is closer to the quinoline ring than it is in MPQ, which accounts for the higher electronic density in the former. The most significant effect occurs in the correspondent protonated

    Endocrine regulation of fluids and electrolytes during seven days of 6 deg head down bed rest (HDBR) was compared in male (n = 8) and, for the first time, female (n = 8) volunteers. The subjects' responses to quiet standing for 2 hr before and after HDBR were also tested. In both sexes, diuresis and natriuresis were evident during the first 2-3 days of HDBR, resulting in a marked increase in the urinary Na/K ratio and significant Na retention on reambulation. After the first day of HDBR, plasma renin activity (PRA) was increased relative to aldosterone, plasma volume was decreased, and the renal response to aldosterone appeared to be appropriate. Circulating levels of arginine vasopressin (AVP), cortisol, and ACTH were unchanged during HDBR. Plasma testosterone decreased slightly on day 2 of HDBR in males. The ratio of AM ACTH to cortisol was lower in females than in males because ACTH was lower in females. Urinary cortisol increased and remained elevated throughout the HDBR in males only. There were no gender differences in the responses to 7 day HDBR, except those in the pituitary-adrenal system; those differences appeared unrelated to the postural change. The provocative cardiovascular test of quiet standing before and after bed rest revealed both sex differences and effects of HDBR. There were significant sex differences in cardiovascular responses to standing, before and after HDBR. Females had greater PRA and aldosterone responses to standing before bedrest and larger aldosterone responses to standing after HDBR than males. Cardiovascular responses to standing before and after bedrest differed markedly: arterial pressure and heart rates increased with standing before HDBR, by contrast, arterial pressure decreased, with greater increases in heart rates after HDBR. In both sexes, all hormonal responses to standing were greater after HDBR. The results show clearly that similar responses to standing as well as to HDBR occur in both sexes, but that females exhibit

From 8 to 21 days (d one single basal diet was used for all treatments. The thirty seven-gram chicks had the smallest yolk sack weight at 4d, smallest body weight (BW and feed intake (FI at 7d and 21d, but the same feed conversion (FC than the other groups of hatching weight. Chicks receiving diet with intermediate GMD had the greatest BW and FI at 7d, but at 21d this effect was no longer seen. The diet with finest particle size resulted in birds with the smallest gizzard weight at 7d. The 0.12%Na diet was statistically different from the other Na levels, resulting in chicks at 7d with the worst FC and lowest body weights. At 21d, BW still was the lowest for this group of chicks. Birds with 0.48%Na produced more watery excreta and less dry matter in the carcass at 7d. Water consumption (C H2O was influenced linearly by chick weight up to 0.36%Na level. In the 0.48%Na level, 40 and 44 g chicks had similar C H2O, which was different from 37-g chicks. For best performance, Na values were set from 0.31 to 0.48%. The three studied factors influenced quality of pre-starter diet and consequently chick performance.

This could be an adaptive mechanism at the initial stages of toxicity from lead exposure due to oxidative stress. We evaluated whether lead alters the participation of K{sup +} channels and Na{sup +}/K{sup +}-ATPase (NKA) on vascular function. Wistar rats were treated with lead (1st dose 4 μg/100 g, subsequent doses 0.05 μg/100 g, im, 7 days) or vehicle. Lead treatment reduced the contractile response of aortic rings to phenylephrine (PHE) without changing the vasodilator response to acetylcholine (ACh) or sodium nitroprusside (SNP). Furthermore, this treatment increased basal O{sub 2}{sup −} production, and apocynin (0.3 μM), superoxide dismutase (150 U/mL) and catalase (1000 U/mL) reduced the response to PHE only in the treated group. Lead also increased aortic functional NKA activity evaluated by K{sup +}-induced relaxation curves. Ouabain (100 μM) plus L-NAME (100 μM), aminoguanidine (50 μM) or tetraethylammonium (TEA, 2 mM) reduced the K{sup +}-induced relaxation only in lead-treated rats. When aortic rings were precontracted with KCl (60 mM/L) or preincubated with TEA (2 mM), 4-aminopyridine (4-AP, 5 mM), iberiotoxin (IbTX, 30 nM), apamin (0.5 μM) or charybdotoxin (0.1 μM), the ACh-induced relaxation was more reduced in the lead-treated rats. Additionally, 4-AP and IbTX reduced the relaxation elicited by SNP more in the lead-treated rats. Results suggest that lead treatment promoted NKA and K{sup +} channels activation and these effects might contribute to the preservation of aortic endothelial function against oxidative stress. -- Highlights: ► Increased free radicals production ► Increased Na{sup +}/K{sup +} ATPase activity ► Promotes activation of the K{sup +} channels and reduced vascular reactivity ► These effects preserve endothelial function against oxidative

    Full Text Available Abstract Background Previous research has shown the oxidizing properties and microbiological efficacies of chlorine dioxide (ClO2. Its clinical efficacies on oral malodor have been evaluated and reported only in short duration trials, moreover, no clinical studies have investigated its microbiological efficacies on periodontal and malodorous bacteria. Thus, the aim of this study was to assess the inhibitory effects of a mouthwash containing ClO2 used for 7 days on morning oral malodor and on salivary periodontal and malodorous bacteria. Methods/Design A randomized, double blind, crossover, placebo-controlled trial was conducted among 15 healthy male volunteers, who were divided into 2 groups. Subjects were instructed to rinse with the experimental mouthwash containing ClO2 or the placebo mouthwash, without ClO2, twice per day for 7 days. After a one week washout period, each group then used the opposite mouthwash for 7 days. At baseline and after 7 days, oral malodor was evaluated with Organoleptic measurement (OM, and analyzed the concentrations of hydrogen sulfide (H2S, methyl mercaptan (CH3SH and dimethyl sulfide ((CH32S, the main VSCs of human oral malodor, were assessed by gas chromatography (GC. Clinical outcome variables included plaque and gingival indices, and tongue coating index. The samples of saliva were microbiologically investigated. Quantitative and qualitative analyses were performed using the polymerase chain reaction-Invader method. Results and Discussion The baseline oral condition in healthy subjects in the 2 groups did not differ significantly. After rinsing with the mouthwash containing ClO2 for 7 days, morning bad breath decreased as measured by the OM and reduced the concentrations of H2S, CH3SH and (CH32S measured by GC, were found. Moreover ClO2 mouthwash used over a 7-day period appeared effective in reducing plaque, tongue coating accumulation and the counts of Fusobacterium nucleatum in saliva. Future research is

    Growth hormone deficient (GHD) patients are currently effectively treated with daily subcutaneous (sc) injections of hGH in the evening, but alternative routes would be attractive. An oral formulationulation of hGH, using an amino-caprilic acid derivative (5-CNAC, Emisphere's eligen® technology) as...... carrier has recently been developed. The aim of this study was to determine if this oral formulation of hGH could be absorbed and be bioactive. Eight GHD men (mean age 50 years) receiving sc hGH therapy were withdrawn from therapy for 7 days and then treated for 7 days orally with tablets of HGH191...... (Novartis). Each tablet contained 100 mg of hGH and 200 mg 5-CNAC. One tablet was given at 08 h and 17 h, and two tablets at 22 h to match nocturnal GH secretion. The patients were studied thrice for 24 hours: at day 7 of washout, at days 1 and 7 of treatment. GH peaks were recorded in all patients...

    AIM: To compare the one-day quadruple therapy with a standard 7-d triple therapy for H pylori eradication in a rural population of China.METHODS: A total of 396 patients with 13C-urea breath test positive for H pylori were assigned into two groups:239 patients received one-day quadruple therapy (amoxicillin 2000 mg qid; metronidazole 500 mg qid; bismuth citrate 900 mg qid and lansoprazole 60 mg once daily)and 157 patients received 7-d standard triple therapy (amoxicillin 1000 mg bid; clarithromycin 500 mg bid and lansoprazole 30 mg bid). All the patients underwent a 13C-UBT to assess the eradication of H pylori infection six weeks after treatment.RESULTS: Two hundred and twenty-nine patients completed the one-day therapy (95.8%) and 148patients completed the 7-d therapy (94.2%). The oneday therapy eradicated H pylori infection in 64 patients (27.95%). In contrast, 103 patients (69.59%) were H pylori negative after the 7-d therapy (P < 0.01).CONCLUSION: This pilot study suggests there is no beneficial effect of the one-day therapy in treatment of H pylori infection compared with the 7-d standard therapy.

    2013-01-01

    BACKGROUND Glucose-6-phosphate dehydrogenase deficiency (G6PD), an x-linked inherited enzymopathy, is a barrier to malaria control because primaquine cannot be readily applied for radical cure in individuals with the condition. In endemic areas, including in Afghanistan, the G6PD status of vivax patients is not routinely determined so the drug is rarely, if ever, prescribed even though it is included as a recommended treatment in local, regional and global guidelines. This study assessed the ...

  16. [Status of the lipid peroxidation system in the tissues of rats following a 7-day flight on the Kosmos-1667 biosatellite].

    Delenian, N V; Markin, A A

    1989-01-01

    Rats flown for 7 days on Cosmos-1667 were for the first time used to measure antioxidative enzymes (superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase), lipid peroxidation products (diene conjugates, malonic dialdehyde, Schiff bases) and tocopherol. Enhanced lipid peroxidation in the heart was completely compensated by activation of antioxidative enzymes. The content of all lipid peroxidation products measured in the liver increased; this was accompanied by a decrease of glutathione peroxidase and an increase of superoxide dismutase activities. It is suggested that lipid peroxidation was activated in response to altered gravity. PMID:2586059

    Full Text Available ANTECEDENTES: la primaquina (PQ es el único medicamento disponible en el mercado para prevenir recurrencias del paludismo por Plasmodium vivax pero varios aspectos suyos se desconocen. OBJETIVO: comparar regímenes de PQ para prevenir recurrencias de malaria vivax. METODOLOGÍA: revisión sistemática de datos. RESULTADOS: 1. ¿Según los estudios descriptivos, la PQ es eficaz para prevenir las recurrencias del paludismo vivax? Sí. La comparación de estudios que no usaron PQ con otros que sí la aplicaron, en cualquier esquema, mostró que si no se usa PQ la recurrencia es altamente probable. 2. ¿Tienen la misma eficacia dosis diarias (mg/kg iguales pero dosis totales diferentes? La dosis total de 75 mg es tanto o más eficaz que la de 210 mg. 3. ¿La eficacia anti-recurrencias depende del lugar donde sucede la infección? Si. Hay variación según país y región. 4. ¿La frecuencia de recurrencias depende del tiempo de seguimiento post tratamiento? La respuesta no es uniforme para todos los lugares. CONCLUSIONES: la PQ resultó eficaz para prevenir las recurrencias, pero no fue 100%. Las dosis totales de 210 y de 75 mg tuvieron igual eficacia, pero 75 mg sólo han sido evaluados en India, donde P. vivax parece ser más sensible a la PQ que en otros lugares. Parece indudable la influencia del lugar en la proporción de recurrencias, incluso con una misma dosis total. El papel del tiempo de seguimiento no resultó claro. Deben evaluarse esquemas alternativos al estándar, que tiene eficacia promedio de 90% o más.BACKGROUND: primaquine (PQ is the only drug available in the market to prevent Plasmodium vivax malaria recurrence, but several aspects are still unknown.

    2014-11-01

    Full Text Available [b]Introduction[/b]. In aerobiological studies it is often necessary to compare concentration data recorded with different models of sampling instrument. Sampler efficiency typically varies from device to device, and depends on the target aerosol and local atmospheric conditions. To account for these differences inter-sampler correction factors may be applied, however for many pollen samplers and pollen taxa such correction factors do not exist and cannot be derived from existing published work. [b]Materials and methods.[/b] In this study, the relative efficiencies of the Burkard 7-Day Recording Volumetric Spore Trap, the Sampling Technologies Rotorod Model 20, and the Burkard Personal Volumetric Air Sampler were evaluated for Urticaceae and Poaceae pollen under field conditions. The influence of wind speed and relative humidity on these efficiency relationships was also assessed. Data for the two pollen taxa were collected during 2010 and 2011–2012, respectively. [b]Results[/b]. The three devices were found to record significantly different concentrations for both pollen taxa, with the exception of the 7-Day and Rotorod samplers for Poaceae pollen. Under the range of conditions present during the study, wind speed was found to only have a significant impact on inter-sampler relationships involving the vertically-orientated Burkard Personal sampler, while no interaction between relative efficiency and relative humidity was observed. [b]Conclusions[/b]. Data collected with the three models of sampler should only be compared once the appropriate correction has been made, with wind speed taken into account where appropriate.

  19. Randomized clinical trial on 7-days-a-week postoperative radiotherapy for high-risk squamous cell head and neck cancer

    Purpose: To evaluate the normal tissue reactions and loco-regional control rates (LRC) in patients treated with 7-days-a-week postoperative continuous irradiation (p-CAIR) compared to conventionally fractionated 5-days-a-week postoperative radiotherapy (CF). Materials/methods: Between 2001 and 2004, 279 patients with high-risk squamous cell cancer of the larynx (158 pts.) or cancer of the oral cavity/oropharynx (121 pts.) were enrolled. They were stratified according to the primary cancer site (larynx vs. others) and the treating center and randomized to receive 63 Gy in fractions of 1.8 Gy given 5-days-a-week (140 pts: CF) or 7-days-a-week (139 pts: p-CAIR). Results: The acute and late toxicity was considered acceptable, although the proportion of patients with confluent mucositis was higher in p-CAIR compared to CF (60.0 vs. 33.3%). The actuarial 3-year LRC were 64 vs. 70% for CF and p-CAIR, respectively, p = 0.32. A statistically significant improvement in 3-year LRC in p-CAIR arm appeared in a subset of the patients with cancer of the oropharynx/oral cavity (74% p-CAIR vs. 53% CF, p = 0.02). By contrast, there was no improvement in LRC in a subset of the patients with cancer of the larynx (p = 0.46). Conclusion: An improvement in LRC attributable to acceleration of postoperative radiotherapy appeared restricted to the patients with cancer of the oropharynx/oral cavity. In patients with cancer of the larynx acceleration of postoperative radiotherapy did not have any beneficial effect

  20. Cytotoxic effects in 3T3-L1 mouse and WI-38 human fibroblasts following 72 hour and 7 day exposures to commercial silica nanoparticles

    The potential toxic effects in murine (3T3-L1) and human (WI-38) fibroblast cell lines of commercially available silica nanoparticles (NPs), Ludox CL (nominal size 21 nm) and CL-X (nominal size of 30 nm) were investigated with particular attention to the effect over long exposure times (the tests were run after 72 h exposure up to 7 days). These two formulations differed in physico-chemical properties and showed different stabilities in the cell culture medium used for the experiments. Ludox CL silica NPs were found to be cytotoxic only at the higher concentrations to the WI-38 cells (WST-1 and LDH assays) but not to the 3T3-L1 cells, whereas the Ludox CL-X silica NPs, which were less stable over the 72 h exposure, were cytotoxic to both cell lines in both assays. In the clonogenic assay both silica NPs induced a concentration dependent decrease in the surviving fraction of 3T3-L1 cells, with the Ludox CL-X silica NPs being more cytotoxic. Cell cycle analysis showed a trend indicating alterations in both cell lines at different phases with both silica NPs tested. Buthionine sulfoximine (γ-glutamylcysteine synthetase inhibitor) combined with Ludox CL-X was found to induce a strong decrease in 3T3-L1 cell viability which was not observed for the WI-38 cell line. This study clearly indicates that longer exposure studies may give important insights on the impact of nanomaterials on cells. However, and especially when investigating nanoparticle effects after such long exposure, it is fundamental to include a detailed physico-chemical characterization of the nanoparticles and their dispersions over the time scale of the experiment, in order to be able to interpret eventual impacts on cells. -- Highlights: ► Ludox CL silica NPs are cytotoxic to WI-38 fibroblasts but not to 3T3-L1 fibroblasts. ► Ludox CL-X silica NPs are cytotoxic to both cell lines. ► In clonogenic assay both silica NPs induce cytotoxicity, higher for CL-X silica. ► Cell cycle analysis shows

  1. Randomized clinical trial on continuous 7-days-a-week postoperative radiotherapy for high-risk squamous cell head-and-neck cancer: A report on acute normal tissue reactions

    Background and purpose: To analyse acute mucosal reactions in patients treated with continuous accelerated postoperative irradiation (p-CAIR) compared to conventionally fractionated postoperative radiotherapy (p-CF). Patients and methods: The patients were randomly assigned to receive 63 Gy in 1.8 Gy fractions 7-days-a-week given over a period of 5 weeks (n=88), or 63 Gy in 1.8 Gy fractions given 5-days-a-week over 7 weeks (n=87). It represents 65% of an overall trial size. Acute mucosal reactions were scored using modified Dische system. Polychotomous logistic regression was used to estimate the influence of the selected variables on maximum grade of mucositis, and percent of the body weight loss during radiotherapy. Results: The average maximum Dische score and percent of the patients with confluent mucositis were higher in patients treated with p-CAIR, compared to p-CF (13.3 vs. 10.8 and 54 vs. 27%). Polychotomous logistic regression analysis revealed that fractionation scheme and tumour site have significantly influenced maximum Dische score. Tumour site (laryngeal vs. other) had even stronger influence on maximum Dische score than fractionation scheme. The average residual Dische score 8 weeks after radiotherapy was higher in p-CAIR compared to p-CF (2.1 vs. 1.4), and was, most frequently, related to persistent mucosal erythema (70 vs. 57% of pts.). No severe consequential toxicity of radiotherapy was observed, so far, in the trial. Conclusions: While the incidence, intensity and duration of mucosal reactions was higher in p-CAIR than in p-CF the accelerated treatment can be considered tolerable with respect to acute toxicity. In both arms of the trial slight or moderate mucosal erythema was the most frequent acute side effect, which did not completely subside within 8 weeks after irradiation

    1999-01-01

    Abstract In patients with acromegaly, clinical improvement has been reported after octreotide (OCT) treatment, even in cases of only a moderate suppression of growth hormone (GH) levels. In rats, OCT suppresses IGF-I mRNA expression and generation of serum and tissue IGF-I levels. A direct effect...... of OCT on the IGF system could have therapeutical implications in diabetes mellitus, cardiovascular disease, and certain malignancies in which IGF-I might be involved. The aim of this study was to examine possible GH-independent effects of OCT on IGF components in humans. Six GH-deficient (GHD......) patients were studied for 24 h after each of the following treatment regimens (each of 1 weeks duration): (a) daily s.c. GH injection (2 IU/m(2)); (b) as (a) + continuous s.c. infusion of OCT (200 microg/24 h) by means of a portable pump (Nordic Infuser); (c) no treatment. Serum GH binding protein (GHBP...

    Pigs play a significant role during outbreaks of foot-and-mouth disease (FMD) due to their ability to amplify the virus. It is therefore essential to determine what role vaccination could play to prevent clinical disease and lower virus excretion into the environment. In this study we investigated the efficacy of the double oil emulsion A Malaysia 97 vaccine (>6PD50/dose) against heterologous challenge with an isolate belonging to the A SEA-97 lineage at 4 and 7 days post vaccination (dpv). In addition, we determined whether physical separation of pigs in the same room could prevent virus transmission. Statistically there was no difference in the level of protection offered by 4 and 7 dpv. However, no clinical disease or viral RNA was detected in the blood of pigs challenged 4 dpv, although three of the pigs had antibodies to the non-structural proteins (NSPs), indicating viral replication. Viral RNA was also detected in nasal and saliva swabs, but on very few occasions. Two of the pigs vaccinated seven days prior to challenge had vesicles distal from the injection site, but on the inoculated foot, and two pigs had viral RNA detected in the blood. One pig sero-converted to the NSPs. In contrast, all unvaccinated and inoculated pigs had evidence of infection. No infection occurred in any of the susceptible pigs in the same room, but separated from the infected pigs, indicating that strict biosecurity measures were sufficient under these experimental conditions to prevent virus transmission. However, viral RNA was detected in the nasal swabs of one group of pigs, but apparently not at sufficient levels to cause clinical disease. Vaccination led to a significant decrease in viral RNA in vaccinated pigs compared to unvaccinated and infected pigs, even with this heterologous challenge, and could therefore be considered as a control option during outbreaks.

    Objective: To provide the transcutaneous bilirubin (TcB) value of normal neonates at 7 days after birth in Changzhou region, obtain the average peak value of TcB, provide a basis for clinical diagnosis, draft an hour - specific TcB percentile nomogram suitable for the neonates in the region. Methods: 7 482 TcB values were obtained from 679 healthy full term neonates and near full term neonates by JH20 - 1B percutaneous jaundice apparatus from January to March in 2010, the detection time was from 12 hours after birth until 152 hours after birth. Every TcB percentile for each designated time was calculated and used for drafting an hour - specific nomogram. Results: TcB values varied at different time points among the normal neonates at 12 ~ 152 hours after birth, peaked at 116 hours after birth, the proportion of neonatal hyperbilirubinemia (TcB>12.9 mg/dL) was 8.4% (57/679) , no bilirubin encephalopathy occurred during follow - up after leaving the hospital TcB nomogram reflected the natural history of TcB among the normal neonates at 7 days after birth. The average peak value of bilirubin was (10.0 ±2. 2) mg/dL, the P40, P75 and P95 of bilirubin were 8. 3 mg/dL, 10. 8mg/dL and 12.6 mg/dL, respectively. Among the perinatal factors, TcB level was significantly associated with gestational age, premature rupture of membrane and cephalhematoma (P < 0. 05) . Conclusion: The appearance time and peak time of neonatal jaundice in Changzhou region are similar to the published reports at home and abroad; the diagnostic criterion of neonatal hyperbilirubinemia in China should be higher than current criterion, thus, the interventional standard of hyperbilirubinemia should be improved correspondingly.%目的:提供常州地区正常新生儿生后7天经皮胆红素(TcB)值,得出胆红素的平均峰值,为临床诊断奠定基础并制定一份适合本地区新生儿小时TcB百分位列线图.方法:2010年1~3月679例健康足月和近足月新生儿采用JH20 - 1B

    Purpose: To report long-term results of randomized trial comparing 2 accelerated fractionations of definitive radiation therapy assessing the need to irradiate during weekend in patients with head and neck squamous cell carcinoma. Methods and Materials: A total of 345 patients with SCC of the oral cavity, larynx, and oro- or hypo-pharynx, stage T2-4N0-1M0, were randomized to receive continuous accelerated irradiation (CAIR: once per day, 7 days per week) or concomitant accelerated boost (CB: once per day, 3 days per week, and twice per day, 2 days per week). Total dose ranged from 66.6-72 Gy, dose per fraction was 1.8 Gy, number of fractions ranged from 37-40 fractions, and overall treatment time ranged from 37-40 days. Results: No differences for all trial end-points were noted. At 5 and 10 years, the actuarial rates of local-regional control were 63% and 60% for CAIR vs 65% and 60% for CB, and the corresponding overall survival were 40% and 25% vs 44% and 25%, respectively. Confluent mucositis was the main acute toxicity, with an incidence of 89% in CAIR and 86% in CB patients. The 5-year rate of grade 3-4 late radiation morbidity was 6% for both regimens. Conclusions: Results of this trial indicate that the effects of accelerated fractionation can be achieve by delivering twice-per-day irradiation on weekday(s). This trial has also confirmed that an accelerated, 6-weeks schedule is a reasonable option for patients with intermediate-stage head-and-neck squamous cell carcinoma because of the associated high cure rate and minimal severe late toxicity.

  12. Factors associated with delays in treatment initiation after tuberculosis diagnosis in two districts of India.

    Durba Paul

    Full Text Available BACKGROUND: Excessive time between diagnosis and initiation of tuberculosis (TB treatment contributes to ongoing TB transmission and should be minimized. In India, Revised National TB Control Programme (RNTCP focuses on indicator start of treatment within 7 days of diagnosis for patients with sputum smear-positive PTB for monitoring DOTS implementation. OBJECTIVES: To determine length of time between diagnosis and initiation of treatment and factors associated with delays of more than 7 days in smear-positive pulmonary TB. METHODS: Using existing programme records such as the TB Register, treatment cards, and the laboratory register, we conducted a retrospective cohort study of all patients with smear-positive pulmonary TB registered from July-September 2010 in two districts in India. A random sample of patients with pulmonary TB who experienced treatment delay of more than 7 days was interviewed using structured questionnaire. RESULTS: 2027 of 3411 patients registered with pulmonary TB were smear-positive. 711(35% patients had >7 days between diagnosis and treatment and 262(13% had delays >15 days. Mean duration between TB diagnosis and treatment initiation was 8 days (range = 0-128 days. Odds of treatment delay >7 days was 1.8 times more likely among those who had been previously treated (95% confidence interval [CI] 1.5-2.3 and 1.6 (95% CI 1.3-1.8 times more likely among those diagnosed in health facilities without microscopy centers. The main factors associated with a delay >7 days were: patient reluctance to start a re-treatment regimen, patients seeking second opinions, delay in transportation of drugs to the DOT centers and delay in initial home visits. To conclude, treatment delay >7 days was associated with a number of factors that included history of previous treatment and absence of TB diagnostic services in the local health facility. Decentralized diagnostic facilities and improved referral procedures may reduce such treatment

    severe malaria should also be treated with empirical broad spectrum antibiotics until bacterial infection can be excluded (Grade 1B). 15. Haemolysis occurs in approximately 10-15% patients following intravenous artesunate treatment. Haemoglobin concentrations should be checked approximately 14 days following treatment in those treated with IV artemisinins (Grade 2C). 16. Falciparum malaria in pregnancy is more likely to be complicated: the placenta contains high levels of parasites, stillbirth or early delivery may occur and diagnosis can be difficult if parasites are concentrated in the placenta and scanty in the blood. 17. Uncomplicated falciparum malaria in the second and third trimester of pregnancy should be treated with artemether-lumefantrine (Grade 2B). Uncomplicated falciparum malaria in the first trimester of pregnancy should usually be treated with quinine and clindamycin but specialist advice should be sought. Severe malaria in any trimester of pregnancy should be treated as for any other patient with artesunate preferred over quinine (Grade 1C). 18. Children with uncomplicated malaria should be treated with an ACT (artemether-lumefantrine or dihydroartemisinin-piperaquine) as first line treatment (Grade 1A). Quinine with doxycycline or clindamycin, or atovaquone-proguanil at appropriate doses for weight can also be used. Doxycycline should not be given to children under 12 years. 19. Either an oral ACT or chloroquine can be used for the treatment of non-falciparum malaria. An oral ACT is preferred for a mixed infection, if there is uncertainty about the infecting species, or for P. vivax infection from areas where chloroquine resistance is common (Grade 1B). 20. Dormant parasites (hypnozoites) persist in the liver after treatment of P. vivax or P. ovale infection: the only currently effective drug for eradication of hypnozoites is primaquine (1A). Primaquine is more effective at preventing relapse if taken at the same time as chloroquine (Grade 1C). 21

  14. ECIL guidelines for treatment of Pneumocystis jirovecii pneumonia in non-HIV-infected haematology patients.

    2016-09-01

    The initiation of systemic antimicrobial treatment of Pneumocystis jirovecii pneumonia (PCP) is triggered by clinical signs and symptoms, typical radiological and occasionally laboratory findings in patients at risk of this infection. Diagnostic proof by bronchoalveolar lavage should not delay the start of treatment. Most patients with haematological malignancies present with a severe PCP; therefore, antimicrobial therapy should be started intravenously. High-dose trimethoprim/sulfamethoxazole is the treatment of choice. In patients with documented intolerance to this regimen, the preferred alternative is the combination of primaquine plus clindamycin. Treatment success should be first evaluated after 1 week, and in case of clinical non-response, pulmonary CT scan and bronchoalveolar lavage should be repeated to look for secondary or co-infections. Treatment duration typically is 3 weeks and secondary anti-PCP prophylaxis is indicated in all patients thereafter. In patients with critical respiratory failure, non-invasive ventilation is not significantly superior to intubation and mechanical ventilation. The administration of glucocorticoids must be decided on a case-by-case basis. PMID:27550993

    2014-04-01

    Full Text Available Childrenwith Helicobacter infection need treatment. The aim of treatment is elimination of H.Pylori. Most patients with this infection are asymptomatic and without peptic disease. Treatment and management of these patients are controversy. Conventional Treatment: The best treatment for H. pylori eradication regimens should have cure rates of at least 80%, be without major side effects, and induce minimal bacterial resistance. Antibiotics alone have not achieved this. Luminal acidity influences both the effectiveness of some antimicrobial agents and the survival of the bacteri; thus antibiotics have been combined with acid suppression such as proton pump inhibitors (PPIs, bismuth, or H2 antagonists. The “classic” regimen is treatment twice daily for 7 days with a PPI and clarithromycin plus either amoxicillin or metronidazole Bismuth has been used in the treatment of peptic ulcer disease and 1 part o quadruple therapy for H.Pylori but compliance of children for it is low.   Sequential Therapy  Sequential therapyinvolves dual therapy with a PPI and amoxicillin for 5 days followed sequentially by clarithromycin, Tinidazole and omeperazole for 5 days or other triple therapy for 7 days. This treatment has had 97% efficacy.   Adjunctive Therapies A number of studies have showed the potential benefits of probiotic therapy in H. pylori treatment regimens.Consumption of these drugs accompanied with other medications increase H.Pylori eradication.

    2003-01-01

    AIM:Systemic treatment with epidermal growth factor (EGF)leads to growth of all parts of the small intestine in normal functioning rats. In this study, we investigated the effect of this growth process on morphometric and biomechanical parameters of ileum.METHODS: Rats were treated with EGF (150 μg@kg-1day-1)or placebo via osmotic minipumps for 2, 4, 7, and 14 days.A segment of ileum was removed. The morphology at noload state and zero-stress state was measured and passive biomechanical properties were assessed using a biaxial test machine (combined inflation and axial stretching).RESULTS: The ileum weight increased after EGF administration. After 4 days' EGF treatment, the wall thickness was increased. Significantly smaller inner perimeters were seen in 4 day and 7 day EGF treatment groups. The opening angle and residual strain began to increase after 7 days' EGF treatment. Wall stiffness, evaluated from the stress-strain curves, showed a continuous decrease in circumferential direction during the first 7 days' EGF treatment. The longitudinal stiffness increased during the first 7 days. The stress-strain curves for both circumferential and longitudinal direction tended to shift back to normal 14days after starting EGF administration.CONCLUSION: EGF can cause significant changes both in the morphology and in the passive mechanical properties of the rat ileum.

    2004-01-01

    Neovascular glaucoma (NVG) is a pathological condition of the eye with fast deterioration, accompanied with eyeball pain and loosing sight. The aim of the study was to examine the efficacy of cryotherapy in the treatment of NVG which is resistant to medical and surgical therapy, concerning intraocular pressure (IOT) and eyeball pain immediately after the treatment and 6 months after. In the Department of Ophthalmology, Split University Scool of Medicine, during three years 70 patients with NVG, which were resistant to medical and surgical treatment, were included in the prospective study. There were 50 males and 21 women, average age 74 +/- 6.94 (45-87). The patients were treated with transconjuctival cyclocryocoagulation, machine ERBOKRYIO AE-ERBE was used. The average value of IOT was: at admission 44.8 mmHg, 7 days after the treatment 30.7 mmHg with the tendency of falling down 30 and 90 days later, to finally 19.9 mmHg 180 days after the treatment. The IOT was significantly lower after the treatment. At admission, the average value of eyeball pain intensity was high (4.2), 7 days after the treatment it was 2.1 with the tendency of falling down to finally 1.1 180 days after the treatment. The eyeball pain intensity was significantly lower after the treatment. Cyclocryocoagulation is a method of choice in the treatment of NVG resistant to medical and surgical treatment. Cyclocryocoagulation, as a treatment of noncontrolled progressive NVG, does not have any effect on the improvement of sight in these patient. PMID:15918320

    An HIV-negative man with pharyngeal gonorrhea had a positive test-of-cure (nucleic acid amplification test) result 7 days after treatment with ceftriaxone/azithromycin. Neisseria gonorrhoeae Multi-Antigen Sequencing Type 1407 and mosaic pen A (XXXIV) gene were identified in the test-of-cure specimen, and culture was negative. Retreatment with ceftriaxone 500 mg intramuscularly plus azithromycin 2 g orally yielded a negative test-of-cure result. PMID:26967304

  7. THE IMPACT OF ENVIRONMENTALLY FRIENDLY POSTHARVEST TREATMENTS ON THE ANTIOXIDANT ACTIVITY OF STRAWBERRY FRUITS DURING STORAGE

    Ivna Štolfa

    2014-12-01

    Full Text Available Proper postharvest storage is an effective way to maintain the quality and nutritional values of fruits. The aim of this study was to determine how environmentally friendly postharvest treatments with salicylic acid solution, colloidal silver solution and ozone, affect the antioxidant activity of strawberry fruits (Fragaria x ananassa Duch. cv. Albion during 7 days of storage at 4°C. The content of ascorbic acid, total phenols and antioxidant activity of strawberry fruits were determined spec-trophotometrically. After 7 days of storage in strawberry fruits treated with all three treatments separately, the contents of ascorbic acid were higher than in the control fruits, supporting the usefulness of these treatments for preserving fruit quality and nutritional value during storage. The treatment with salicylic acid solution showed the most beneficial effect during storage causing a significant increase in the content of ascorbic acid, phenols and antioxidant activity at the end of the storage period.

  8. Tafenoquine and its potential in the treatment and relapse prevention of Plasmodium vivax malaria: the evidence to date

    Ebstie, Yehenew A; Abay, Solomon M; Tadesse, Wondmagegn T; Ejigu, Dawit A

    2016-01-01

    Despite declining global malaria incidence, the disease continues to be a threat to people living in endemic regions. In 2015, an estimated 214 million new malaria cases and 438,000 deaths due to malaria were recorded. Plasmodium vivax is the second most common cause of malaria next to Plasmodium falciparum. Vivax malaria is prevalent especially in Southeast Asia and the Horn of Africa, with enormous challenges in controlling the disease. Some of the challenges faced by vivax malaria-endemic countries include limited access to effective drugs treating liver stages of the parasite (schizonts and hypnozoites), emergence/spread of drug resistance, and misperception of vivax malaria as nonlethal. Primaquine, the only 8-aminoquinoline derivative approved by the US Food and Drug Administration, is intended to clear intrahepatic hypnozoites of P. vivax (radical cure). However, poor adherence to a prolonged treatment course, drug-induced hemolysis in patients with glucose-6-phosphate dehydrogenase deficiency, and the emergence of resistance make it imperative to look for alternative drugs. Therefore, this review focuses on data accrued to date on tafenoquine and gives insight on the potential role of the drug in preventing relapse and radical cure of patients with vivax malaria.

  16. Pivmecillinam in the treatment of urinary tract infections.

    Nicolle, L E

    2000-09-01

    The efficacy of pivmecillinam for empirical treatment of acute uncomplicated urinary tract infection (UTI) was initially reported in clinical trials published in the 1970s and 1980s. Bacteriological cure rates observed in these trials were consistently >85%, and studies of different dosing regimens suggested that a 3 day course was appropriate. Comparative studies reported that pivmecillinam was equivalent to other antimicrobial agents in terms of clinical and bacteriological outcomes. These studies also documented that pivmecillinam was effective for treatment of Staphylococcus saprophyticus infections, was acceptable for use in pregnancy and was well tolerated. Subsequent widespread use of pivmecillinam in Scandinavian countries has led to a body of clinical experience which confirms the efficacy and safety of this antimicrobial agent in the treatment of acute cystitis. Recently, two large, prospective, randomized, double-blind, multi-centre clinical trials have been completed to assist in defining the role of this antimicrobial agent in the treatment of acute cystitis. A comparison of 3 day courses of pivmecillinam or norfloxacin, both at 400 mg bd, showed higher bacteriological cure rates with norfloxacin but generally similar clinical outcomes. A second, dose-ranging study found that pivmecillinam, given bd for 7 days, led to superior bacteriological and clinical outcomes at short-term follow-up than the 3 day regimen. Pooling bacteriological outcomes from the two studies showed similar outcomes with 7 days of pivmecillinam 200 mg bd or 3 days of norfloxacin 400 mg bd. The shorter, 3 day, course achieved similar short-term clinical outcomes to 7 days of pivmecillinam and 3 days of norfloxacin in women aged pivmecillinam is effective and well tolerated for the treatment of acute cystitis in women.

  2. Empirical treatment of acute cystitis in women.

    Nicolle, Lindsay E

    2003-07-01

    Empirical antimicrobial treatment for acute cystitis in women requires continuing reassessment as the antimicrobial susceptibility of community isolates of Escherichia coli evolves. Current recommendations for 3 days trimethoprim or trimethoprim/sulphamethoxazole are compromised by increasing resistance of community E. coli to these agents. Fluoroquinolones are an alternate 3-day therapy, but increasing resistance is being reported from some countries, and widespread community use may promote resistance, limiting effectiveness of these agents for more serious infections. Alternate regimens supported by recent clinical trials suggest pivmecillinam given twice daily for 7 days is as effective as 3 days of quinolone therapy, while microbiological cure is 80% with 3 days therapy twice daily, and 90% with 3 days therapy thrice daily. Nitrofurantoin given for 7 days has a cure rate of 80-85%. Fosfomycin trometamol as a single dose has cure rates of 75-85%. All these agents are effective, but a compromise in efficacy or duration of therapy compared with current 3-day regimens may have to be considered. PMID:12842322

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

    2013-06-01

    Full Text Available INTRODUCTION: Patients usually experience pain during orthodontic treatment. This fact can affect cooperation and the development of treatment. Reporting pain during treatment seems to be influenced by emotional aspects such as the patient's motivation. OBJECTIVE: To assess the relationship between patient's motivation and the intensity of reported pain during two stages of treatment. METHODS: Twenty males (11-37 years old answered a questionnaire divided into five categories regarding their motivation towards treatment. The subjects were studied for 14 days (7 days with bonded brackets and 7 days with the initial arch inserted and the intensity of pain was evaluated on a daily basis. All the issues, including the intensity of pain, were measured through the visual analog scale (VAS. RESULTS: The VAS-associated questionnaire proved to have good temporal reliability and reasonable internal consistency, being that the "perceived severity" domain had the greatest, although not significant (p = 0.196 correlation with pain intensity. Only the question asking the patients if they thought that their teeth were too uneven showed a positive correlation with pain intensity (p = 0.048. CONCLUSION: The results seem to indicate that the five categories related to treatment motivation cannot be used to predict discomfort during treatment. In addition, patients who think their teeth are too uneven may experience more severe pain due to greater force application after insertion of the initial arch.

    Background Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzyme defect and affects more than 400 million people worldwide. This deficiency is believed to protect against malaria because its global distribution is similar. However, this genetic disorder may be associated with potential hemolytic anemia after treatment with anti-malarials, primaquine or other 8-aminoquinolines. Although primaquine is used for malaria prevention, no study has previously investigate...

    Full Text Available Background & objectives: Chloroquine (CQ, followed by 14-day primaquine, is the recommended regimen forthe treatment of Plasmodium vivax infection in Thailand. CQ resistant P. vivax (CRPv has not yet challengedthe efficacy of the drug. The present study was conducted to assess the current response of P. vivax to CQ alonein Thailand.Methods: A 28-day in vivo therapeutic efficacy study was conducted from June 2009 to December 2010 in 4sentinel sites. Recurrence of parasitaemia and the clinical condition of patients were assessed on each visitduring follow-up. The drug levels in recurrent patients’ blood were measured using HPLC. Data were analyzedusing the WHO 2008 program for the analysis of in vivo tests.Results: Of the total 212 patients included in the study, 201 completed the 28-days follow-up, while 11 wereexcluded. In five patients (2.5%, parasitaemia reappeared within the 28-days follow-up. On the day of recurrentparasitaemia, the level of chloroquine/desethylchloroquine (CQ-DCQ was above the minimum effectiveconcentration (>100 ng/ml in one patient, but lower in four patients.Conclusion: Reappearance of the parasite within 28 days of follow-up in one of five patients was due to parasiteresistance to CQ. The 2.5% prevalence of CQ treatment failure for P. vivax malaria in the study areas signals theneed to launch monitoring activities for CQ resistant P. vivax in malaria endemic areas in order to detect furtherdevelopment of parasite resistance and to estimate the level of burden across the country

  11. Focused Screening and Treatment (FSAT: a PCR-based strategy to detect malaria parasite carriers and contain drug resistant P. falciparum, Pailin, Cambodia.

    Stefan Hoyer

    Full Text Available Recent studies have shown that Plasmodium falciparum malaria parasites in Pailin province, along the border between Thailand and Cambodia, have become resistant to artemisinin derivatives. To better define the epidemiology of P. falciparum populations and to assess the risk of the possible spread of these parasites outside Pailin, a new epidemiological tool named "Focused Screening and Treatment" (FSAT, based on active molecular detection of asymptomatic parasite carriers was introduced in 2010. Cross-sectional malariometric surveys using PCR were carried out in 20 out of 109 villages in Pailin province. Individuals detected as P. falciparum carriers were treated with atovaquone-proguanil combination plus a single dose of primaquine if the patient was non-G6PD deficient. Interviews were conducted to elicit history of cross-border travel that might contribute to the spread of artemisinin-resistant parasites. After directly observed treatment, patients were followed up and re-examined on day 7 and day 28. Among 6931 individuals screened, prevalence of P. falciparum carriers was less than 1%, of whom 96% were asymptomatic. Only 1.6% of the individuals had a travel history or plans to go outside Cambodia, with none of those tested being positive for P. falciparum. Retrospective analysis, using 2010 routine surveillance data, showed significant differences in the prevalence of asymptomatic carriers discovered by FSAT between villages classified as "high risk" and "low risk" based on malaria incidence data. All positive individuals treated and followed-up until day 28 were cured. No mutant-type allele related to atovaquone resistance was found. FSAT is a potentially useful tool to detect, treat and track clusters of asymptomatic carriers of P. falciparum along with providing valuable epidemiological information regarding cross-border movements of potential malaria parasite carriers and parasite gene flow.

    Chopping, water sprinkling, storage under aerobic and anaerobic conditions, urea, wood ash, activated charcoal and polyethylene glycol 4000 (PEG) treatments were evaluated for their efficiency in deactivating tannins in shrub foliage. In a first trial, fresh leaves of Acacia cyanophylla Lindl. (acacia) were stored after chopping or without chopping and spraying or without spraying with water under aerobic or anaerobic conditions. The plant material was stored for 1, 7 and 14 days and analysed thereafter for extractable total phenols (TP), extractable total tannins (TT) and extractable condensed tannins (CT) contents. Chopping and water spraying substantially decreased the levels of TP, TT and CT of acacia. The rate of tannin deactivation increased in acacia stored under anaerobic conditions. Acacia stored for 7 days exhibited lower TP, TT and CT contents than that stored for only 1 day. Compared to the 7-day storage period, there was a further non-significant decrease in the level of these phenolic compounds when the storage duration was extended to 14 days. The highest level of rumen degradation of crude protein (CP) in sheep rumen was obtained with chopped, water sprinkled acacia leaves stored under anaerobic conditions. The second trial investigated the effect of increasing levels of urea (0, 20, 40, 60 and 80 g/kg) and treatment duration (7, 14, 21 and 28 days) on CP, TP, TT and CT in acacia leaves. The 20 g/kg urea level was sufficient to totally deactivate tannins in acacia even with the shortest storage period, i.e. 7 days. However, urea treatment increased ash-free neutral detergent fibre content and did not improve in sacco acacia degradation. In the third trial air-dried 1 mm ground samples of acacia and kermes oak (Quercus coccifera L.) leaves were added to water (control), acacia wood ash, activated charcoal or PEG solutions (100 g/kg) at 1:10 (w/v) and shaken for 20 min. All these four treatments decreased TP, TT and CT contents and could be classified

    1999-12-01

    Full Text Available Frostbite, the severest form of cold injury, is a major health hazard and a serious medical problem for theArmed Forces operating in snow-bound areas at high altitudes. Detailed experiments on susceptibility, preventionand treatment were conducted to find out suitable measures to prevent, treat and ameliorate wld injuries.Experiments conducted on monkeys have shown that animals with higher  peripheral vascular response me betterprotected against cold injury. Measurements of cold-induced vasodilatation (CIVD, heat output and peripheralblood flow under local cold stress can be used to screen out highly prone individuals to frostbite. Coldacclimatisation was effective in raising the peripheral vascular response and thereby lessening the degree ofinjury. Frostbite having occurred, its treatment is not very satisfactory. This is primarily due to the time lagbetween occurrence of frostbite and initiation of therapy, which plays a vital role in its curative action. Keepingthis in view, many experiments have been wnductedon this treatment. Pilot studies were carriedoutusing variousdrugs and vitamins, and also procedures like rapid rewarming in warm water, tea decoction, turnip (shalgumdecoction, etc., singly as well as in combination, for treatment. The most encouraging result was obtained by theprocedure of rapid rewarming in tea decoction maintained at 37-39 "C immediately after cold exposure, followedby combined therapy of aspirin (5 mgtkg and pentoxifylline (40 mgkg along with vitamin C (50 mglkg twicedaily for 7 days.

    2011-04-01

    National Danish guidelines for the diagnosis and treatment of Helicobacter pylori (Hp) infection have been approved by the Danish Society for Gastroenterology. All patients with peptic ulcer disease, gastric cancer, and MALT lymphoma should be tested for Hp. We also recommend testing in first degree relatives to patients with gastric cancer, in NSAID-naive patients, who need long-term NSAID therapy, and in patients presenting with dyspepsia and no alarm symptoms. Non-endoscoped patients can be tested with a urea-breath test or a faecal antigen test. Endoscoped patients can be tested with a rapid urease test. Proton pump inhibitor therapy should be stopped at least 1 week prior to Hp testing. All infected patients should be offered Hp eradication therapy. First-line treatment is 7-day triple therapy with a proton pump inhibitor and clarithromycine in combination with metronidazole or amoxicilline. Quadruple therapy for 2 weeks with bismuthsubsalicylate, tetracycline, metronidazole and a proton pump inhibitor is recommended in case of treatment failure. Hp testing should be offered to all patients after eradication therapy but is mandatory in patients with ulcer disease, noninvasive gastric cancer or MALT lymphoma. Testing after eradication should not be done before 4 weeks after treatment has ended. PMID:21466771

    Full Text Available Nicola R Armstrong1, Janet D Wilson21Department of Infectious Diseases and Sexual Health, Trinity Centre, Bradford, UK; 2The Centre for Sexual Health, The General Infirmary at Leeds, Leeds, UKAbstract: Bacterial vaginosis (BV is the commonest cause of vaginal discharge in women of childbearing age. Oral metronidazole has long been established as an effective therapy in the treatment of BV. However, adverse effects due to metronidazole are frequent and this may lead to problems with adherence to a 7-day course of treatment and subsequently result in treatment failure. Oral tinidazole has been used to treat bacterial vaginosis for over 25 years but in a number of different dosage regimens. Placebo controlled trials have consistently shown increases in cure rate with tinidazole. Longer courses of treatment (eg, 1 g daily for 5 days appear to be more effective than a 2 g oral single dose. Comparative studies suggest that oral tinidazole is equivalent to oral metronidazole, intravaginal clindamycin cream, and intravaginal metronidazole tablets, in efficacy in treating BV. However, tinidazole has a more favorable side effect profile than oral metronidazole notably with better gastrointestinal tolerability and less metallic taste. Bacterial vaginosis is associated with high rates of recurrence and appropriate management of such recurrences can prove difficult. Recurrent BV has been linked with persistence of Gardnerella vaginalis after treatment; however the clinical implications of the possible greater activity of tinidazole against G. vaginalis are not yet clear. Repeated courses of oral metronidazole may be poorly tolerated and an alternative but equally effective treatment that is better tolerated may be preferable. In comparison to oral metronidazole, cost is clearly an issue as oral metronidazole is considerably cheaper and available in generic form. However where avoidance of oral metronidazole is necessary because of side effects, oral

  11. Treatment of taeniasis and cysticercosis with praziquantel and albendazole

    Abdulbar Hamid

    2005-12-01

    Full Text Available Recent methods, doses and results of medical treatment on taeniasis/cysticercosis, a zoo-notic parasitic disease caused by Taenia solium and Taenia saginata are discussed. In cases of cysticercosis T. solium, especially neurocysticercosis the optimal length and dose of albendazole is a course of 8 days with doses of 15 mg/kg/day divided in two times added by 50 mg/day of prednisone in the morning. The drug is effective in almost any location of the parasites for 80-90% of macroscopic cysts seen by imaging studies. For taeniasis a single dose of praziquantel, 10-15 mg/kg achieves cure rates of more than 90%. Side effects such as nausea, headache and abdominal pain are mild.  Evaluation of drug treatment is done by clinical, radiological and serological evaluation. In Papua (=Irian Jaya nine cases with suspected neurocysticercosis, serologically positive, were treated with 1200 mg single dose albendazole for 15 days. Prednisonetablets, three times daily one tablet, 5 mg during 7 days were added. After one year 6 cases were still serologic positive. At the same time praziquantel, 1200 mg, single dose was given to ten cases during 15 days and prednisone tablets, 3 times daily one tablet, 5 mg during 7 days. After one year 5 sero-positive cases were still found. Albendazole and praziquantel are both effective drugs for taeniasis and cysticercosis, with minor side effects. In addition symptomatic treatment should be given if necessary. (Med J Indones 2005; 14:253-7Keywords: albendazol, praziquantel, cysticercosis, taeniasis

    2010-07-01

    Full Text Available Abstract Objectives To compare three methods for evaluating treatment adherence in a 7-day controlled treatment period for malaria in children in Rwanda. Methods Fifty-six children ( Results Medication adherence data were available for 54 of the 56 patients. Manual pill count and patient self-report yielded a medication adherence of 100% for the in- and out-patient treatment periods. Based on electronic pill-box monitoring, medication adherence during the seven-day treatment period was 90.5 ± 8.3%. Based on electronic pill-box monitoring inpatient medication adherence (99.3 ± 2.7% was markedly higher (p Conclusion Health workers' medication adherence was good. However, a significant lower medication adherence was observed for consumers' adherence in the outpatient setting. This was only detected by electronic pill-box monitoring. Therefore, this latter method is more accurate than the two other methods used in this study.

  13. Tioconazole 2% cream in the treatment of Trichomonas vaginalis or mixed vaginal infections.

    Donadio, C

    1986-01-01

    Twenty patients with documented T. vaginalis infections, six of whom were simultaneously infected with C. albicans and one with G. vaginalis, were treated topically (intravaginally) once daily with 5 g of 2% tioconazole vaginal cream (Trosyd, Pfizer) for 3 consecutive days in an open, non-comparative study. At the first follow-up visit (about 7 days post-treatment), 95% (19/20) of the patients were cured; 95% (18/19) of patients remained cured with respect to the baseline infection at the long-term follow-up (2 months post-treatment) visit, and one patient had a reinfection or relapse with T. vaginalis. Only one patient reported a side-effect, a mild vaginal burning which disappeared with continued treatment. It was concluded that tioconazole 2% vaginal cream is safe and effective for the treatment of T. vaginalis and mixed vaginal infections. PMID:3485546

  14. New treatments for tic disorders.

    Qasaymeh, Mohammad M; Mink, Jonathan W

    2006-11-01

    Tics vary in severity from infrequent and barely noticeable to nearly continuous and highly disruptive. Treatment of tic disorders depends on the severity of the tics, the distress they cause, and the effects they have on school, work, or daily activities. Many tics do not interfere with school or everyday life and do not require specific treatment. Comorbid disorders such as attention deficit hyperactivity disorder, anxiety, and obsessive-compulsive disorder occur in more than 50% of patients. The associated comorbidity can be more bothersome than the tics themselves. Treatment should be aimed at the most troubling symptom. Education and reassurance are often sufficient for mild and occasional tics. For tics of moderate severity, clonidine and guanfacine have a reasonable safety profile. They are considered as first-line medications. With clonidine, start with 0.05 mg at bedtime. Increase as needed and as tolerated by 0.05 mg every 4 to 7 days to a maximum dosage of 0.3 to 0.4 mg/day divided three or four times a day. With guanfacine, start with 0.5 mg at bedtime. The dosage may be increased as needed and as tolerated by 0.5 mg every week to a maximum dosage of 3 to 4 mg/day, divided twice a day. There are emerging data that behavioral therapy is effective for treatment of tics in some individuals. Dopamine receptor blockers are the most potent medications for treating severe tics. The efficacy appears to be proportionate to the affinity for dopamine D2 receptors. Thus, standard antipsychotic medications such as haloperidol, pimozide, or fluphenazine are the most potent. However, these medications commonly cause bothersome side effects. Therefore, we recommend use of atypical neuroleptics before standard neuroleptics in most patients. Risperidone is usually the first choice and may have efficacy for behavior problems that often accompany tics. Start with 0.01 mg/kg/dose once a day; dosage may be increased by 0.02 mg/kg/day at weekly intervals, up to 0.06 mg

    2016-01-01

    Increasing antibiotic resistance and ever stricter control on antibiotic use are a driving force to develop alternatives to antibiotics. One such strategy is the use of multifunctional Host Defense Peptides. Here we examined the protective effect of prophylactic treatment with the D analog of chicken cathelicidin-2 (D-CATH-2) against a respiratory E. coli infection. Chickens were treated with D-CATH-2 in ovo at day 18 of embryonic development or intramuscularly at days 1 and 4 after hatch. At 7 days of age, birds were challenged intratracheally with avian pathogenic E. coli. Protection was evaluated by recording mortality, morbidity (Mean Lesion Score) and bacterial swabs of air sacs at 7 days post-infection. In ovo D-CATH-2 treatment significantly reduced morbidity (63%) and respiratory bacterial load (>90%), while intramuscular treatment was less effective. D-CATH-2 increased the percentage of peripheral blood lymphocytes and heterophils by both administration routes. E. coli specific IgM levels were lower in in ovo treated animals compared to intramuscular D-CATH-2 treatment. In short, in ovo treatment with the Host Defense Peptide derived D-CATH-2 can partially protect chickens from E. coli infection, making this peptide an interesting starting point to develop alternatives to antibiotics for use in the poultry sector.

    2008-07-01

    Full Text Available Abstract Background Mycobacterium tuberculosis infection is an ongoing public health problem in Taiwan. The National Tuberculosis Registry Campaign, a case management system, was implemented in 1997. This study examined this monitoring system to identify and characterize delayed treatment of TB patients. Methods Records of all tuberculosis cases treated in Taiwan from 2002 through 2005 were obtained from the National Tuberculosis Registry Campaign. Initiation of treatment more than 7 days after diagnosis was considered a long treatment delay. Results The study included 31,937 patients. The mean day of delayed treatment was 3.6 days. Most patients were treated immediately after diagnosis. The relationship between number of TB patients and days of delayed treatment after diagnosis exhibited a Power-law distribution. The long tail of the power-law distribution indicated that an extreme number occur cannot be neglected. Tuberculosis patients treated after an unusually long delay require close observation and follow up. Conclusion This study found that TB control is generally acceptabl in Taiwan; however, delayed treatment increases the risk of transmission. Improving the protocol for managing confirmed TB cases can minimize disease transmission.

    Kwack, Jae-Young; You, Seul Ki; Kwon, Yong-Soon

    2016-01-01

    A 40-year-old woman visited our hospital with cyclic hematochezia for four months. The patient had the history of laparoscopic-assisted vaginal hysterectomy because of severe dysmenorrhea two years ago at another tertiary hospital. According to the medical records, the past surgical treatment was incomplete excision of pelvic endometriotic lesions, especially in rectal serosal lesions. A colonoscopy and abdominopelvic computed tomography showed an isolated tumor mimicking neoplasm, in which a biopsy under colonoscopy was performed and the lesion was endometriosis pathologically. Laparoscopic anterior resection (LAR) was performed. There were no complications during intraoperative and postoperative period and the patient was discharged 7 days after the LAR. It is important for reducing of long-term complication like rectal endometriosis that complete and safe excision of pelvic endometriosis with expert surgical strategy. PMID:27375735

    Cardenas, Henry E.; Alexander, Joshua B.; Kupwade-Patil,Kunal; Calle, Luz Marina

    2009-01-01

    This work field tested the use of electrokinetics for delivery of concrete sealing nanoparticles concurrent with the extraction of chlorides. Several cylinders of concrete were batched and placed in immersion at the Kennedy Space Center Beach Corrosion Test Site. The specimens were batched with steel reinforcement and a 4.5 wt.% (weight percent) content of sodium chloride. Upon arrival at Kennedy Space Center, the specimens were placed in the saltwater immersion pool at the Beach Corrosion Test Site. Following 30 days of saltwater exposure, the specimens were subjected to rapid chloride extraction concurrent with electrokinetic nanoparticle treatment. The treatments were operated at up to eight times the typical current density in order to complete the treatment in 7 days. The findings indicated that the short-term corrosion resistance of the concrete specimens was significantly enhanced as was the strength of the concrete.

  2. Auricular Point Acupressure for Chronic Low Back Pain: A Feasibility Study for 1-Week Treatment

    2012-01-01

    Full Text Available Objectives. The objective of this one-group, repeated-measures design was to explore the acceptance of auricular point acupressure (APA to reduce chronic low back pain (CLBP and estimate minimum clinically important differences (MCIDs for pain intensity change. Methods. Subjects received 7-day APA treatment. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point for 7-day. The Brief Pain Inventory Short Form (BPI was used to collect outcome data. Results. A total of 74 subjects participated in the study. Ten subjects dropped out and the retention rate was 87%. Subjects reported a 46% reduction in BPI worst pain, and over 50% reduction in BPI average pain, overall pain severity and pain interference by the end of study, and 62.5% subjects also reported less pain medication use. The MCIDs for the subscale of BPI ranged from .70 to 1.86 points. The percentage improvement of MCIDs from baseline was between 14.5–24.9%. Discussion. APA appears to be highly acceptable to patients with CLBP. A sham group is needed in order to differentiate the true effects of APA from the possible psychological effects of more frequent visits by the auricular therapist and patients’ expectation of the APA treatment.

  3. Symptomatic vaginal candidiasis after pivmecillinam and norfloxacin treatment of acute uncomplicated lower urinary tract infection.

    Menday, A P

    2002-10-01

    The comparative incidence of symptomatic vaginal candidiasis associated with pivmecillinam and norfloxacin treatment in women with acute symptomatic uncomplicated UTI was determined in two randomised, double-blind, clinical trials. Adverse events reported following general enquiry were reviewed. Presence of Candida vaginitis was based upon the specification as such by investigators, the presence of specific symptoms such as genital pruritus and/or the prescription of specific anti Candida therapy. The incidences of Candida vaginitis were as follows; Study 1 pivmecillinam 200 mg tid for 7 days 13 (4.6%), pivmecillinam 200 mg bid for 7 days 7 (2.4%), pivmecillinam 400 mg bid for 3 days 6 (2.1%) and placebo 6 (2.1%), P=0.19. Study 2 pivmecillinam 400 mg bid for 3 days 7 (1.5%), norfloxacin 400 mg bid for 3 days 20 (4.3%), P=0.016. The incidence of Candida vaginitis in women with acute symptomatic uncomplicated UTI given 3 days treatment with pivmecillinam 400 mg bid is similar to that seen with placebo and is significantly less than the incidence with norfloxacin 400 mg bid for 3 days.

  4. Sewage Treatment

    1976-01-01

    A million gallon-a-day sewage treatment plant in Huntington Beach, CA converts solid sewage to activated carbon which then treats incoming waste water. The plant is scaled up 100 times from a mobile unit NASA installed a year ago; another 100-fold scale-up will be required if technique is employed for widespread urban sewage treatment. This unique sewage-plant employed a serendipitous outgrowth of a need to manufacture activated carbon for rocket engine insulation. The process already exceeds new Environmental Protection Agency Standards Capital costs by 25% compared with conventional secondary treatment plants.

    Anil Pandit

    Full Text Available OBJECTIVE: To assess the efficacy of gatifloxacin versus cefixime in the treatment of uncomplicated culture positive enteric fever. DESIGN: A randomized, open-label, active control trial with two parallel arms. SETTING: Emergency Room and Outpatient Clinics in Patan Hospital, Lagankhel, Lalitpur, Nepal. PARTICIPANTS: Patients with clinically diagnosed uncomplicated enteric fever meeting the inclusion criteria. INTERVENTIONS: Patients were allocated to receive one of two drugs, Gatifloxacin or Cefixime. The dosages used were Gatifloxacin 10 mg/kg, given once daily for 7 days, or Cefixime 20 mg/kg/day given in two divided doses for 7 days. OUTCOME MEASURES: The primary outcome measure was fever clearance time. The secondary outcome measure was overall treatment failure (acute treatment failure and relapse. RESULTS: Randomization was carried out in 390 patients before enrollment was suspended on the advice of the independent data safety monitoring board due to significant differences in both primary and secondary outcome measures in the two arms and the attainment of a priori defined endpoints. Median (95% confidence interval fever clearance times were 92 hours (84-114 hours for gatifloxacin recipients and 138 hours (105-164 hours for cefixime-treated patients (Hazard Ratio[95%CI] = 2.171 [1.545-3.051], p<0.0001. 19 out of 70 (27% patients who completed the 7 day trial had acute clinical failure in the cefixime group as compared to 1 out of 88 patients (1% in gatifloxacin group(Odds Ratio [95%CI] = 0.031 [0.004 - 0.237], p<0.001. Overall treatment failure patients (relapsed patients plus acute treatment failure patients plus death numbered 29. They were determined to be (95% confidence interval 37.6 % (27.14%-50.2% in the cefixime group and 3.5% (2.2%-11.5% in the gatifloxacin group (HR[95%CI] = 0.084 [0.025-0.280], p<0.0001.

    Previous animal and clinical studies have shown that acupuncture is an effective alternative treatment in the management of hypertension, but the mechanism is unclear. This study investigated the proteomic response in the nervous system to treatment at the Taichong (LR3) acupoint in spontaneously hypertensive rats (SHRs). Unanesthetized rats were subject to 5-min daily acupuncture treatment for 7 days. Blood pressure was monitored over 7 days. After euthanasia on the 7(th) day, rat medullas were dissected, homogenized, and subject to 2D gel electrophoresis and MALDI-TOF analysis. The results indicate that blood pressure stabilized after the 5th day of acupuncture, and compared with non-acupoint treatment, Taichong-acupunctured rat's systolic pressure was reduced significantly (P<0.01), though not enough to bring blood pressure down to normal levels. The different treatment groups also showed differential protein expression: the 2D images revealed 571 ± 15 proteins in normal SD rats' medulla, 576 ± 31 proteins in SHR's medulla, 597 ± 44 proteins in medulla of SHR after acupuncturing Taichong, and 616 ± 18 proteins in medulla of SHR after acupuncturing non-acupoint. In the medulla of Taichong group, compared with non-acupoint group, seven proteins were down-regulated: heat shock protein-90, synapsin-1, pyruvate kinase isozyme, NAD-dependent deacetylase sirtuin-2, protein kinase C inhibitor protein 1, ubiquitin hydrolase isozyme L1, and myelin basic protein. Six proteins were up-regulated: glutamate dehydrogenase 1, aldehyde dehydrogenase 2, glutathione S-transferase M5, Rho GDP dissociation inhibitor 1, DJ-1 protein and superoxide dismutase. The altered expression of several proteins by acupuncture has been confirmed by ELISA, Western blot and qRT-PCR assays. The results indicate an increase in antioxidant enzymes in the medulla of the SHRs subject to acupuncture, which may provide partial explanation for the antihypertensive effect of acupuncture.

  11. Sensitization associated with stressors and cytokine treatments.

    Anisman, Hymie; Merali, Zul; Hayley, Shawn

    2003-04-01

    Like stressors, interleukin-1beta and tumor necrosis factor-alpha (TNF-alpha) increase hypothalamic-pituitary-adrenal (HPA) activity and monoamine turnover at hypothalamic and extrahypothalamic sites. These effects can be re-elicited more readily upon reintroduction of these challenges (sensitization), depending on their time of re-exposure and the particular system being assessed. Following TNF-alpha administration, the co-expression of corticotropin releasing hormone (CRH) and arginine vasopressin increased within the median eminence, peaking 7-14 days after treatment, and was associated with an early corticosterone sensitization. However, the re-elicitation of sickness symptoms and corticosterone release was most pronounced at lengthy re-exposure intervals (28 days), possibly reflecting histamine release from mast cells. In addition, the cytokine engendered the sensitization of norepinephrine and serotonin utilization, and CRH immunoreactivity at mesocorticolimbic sites, but these effects were most prominent at brief re-exposure intervals (1-7 days). Cytokines may independently prime multiple regulatory systems, and by virtue of the neurochemical changes imparted, have both immediate and proactive influences on the evolution of psychopathology.

  12. Radioiodine treatment of feline hyperthyroidism in Germany

    Aim: Establishment of radioiodine treatment of feline hyperthyroidism in veterinary routine in accordance with German radiation protection regulations. Patients and methods: 35 cats with proven hyperthyroidism were treated with 131I in a special ward. Thyroid uptake and effective halflife were determined using gammacamera dosimetry. Patients were released when measured whole body activity was below the limit defined in the German ''Strahlenschutzverordnung''. Results: 17/20 cats treated with 150 MBq radioiodine and 15/15 cats treated with 250 MBq had normal thyroid function after therapy, normal values for FT3 and FT4 were reached after two and normal TSH levels after three weeks. In 14 cats normal thyroid function was confirmed by controls 3-6 months later. Thyroidal iodine uptake was 24 ± 10%, effective halflife 2.5 ± 0.7 days. Whole body activity 131I. Radiation exposure of cat owners was estimated as 1.97 μSv/MBq for adults. Conclusion: Radioiodine therapy of feline hyperthyroidism is highly effective and safe. It can easily be performed in accordance with German radiation protection regulations, although this requires hospitalisation for approximately two weeks. Practical considerations on radiation exposure of cat owners do not justify this long interval. Regulations for the veterinary use of radioactive substances similar to existing regulations for medical use in humans are highly desirable. (orig.)

  13. Impact of Atraumatic Restorative Treatment (ART on the treatment profile in pilot government dental clinics in Tanzania

    Kikwilu Emil

    2009-06-01

    Full Text Available Abstract Background The predominant mode of treatment in government dental clinics in Tanzania has been tooth extraction because the economy could not support the conventional restorative care which depends on expensive equipment, electricity and piped water systems. Atraumatic Restorative Treatment (ART was perceived as a suitable alternative. A 3.5-year study was designed to document the changes in the treatment profiles ascribed to the systematic introduction of ART in pilot government dental clinics. Methods Dental practitioners who were working in 13 government dental clinics underwent a 7-day ART training. Treatment record data on teeth extracted and teeth restored by the conventional and ART approaches were collected from these clinics for the three study periods. The mean percentage of ART restorations to total treatment, ART restorations to total restorations, and total restorations to total treatments rendered were computed. Differences between variables were determined by ANOVA, t-test and Chi-square. Results The mean percentage of ART restorations to total treatment rendered was 0.4 (SE = 0.5 and 11.9 (SE = 1.1 during the baseline and second follow-up period respectively (ANOVA mixed model; P . The mean percentage of ART restorations to total restorations rendered at baseline and 2nd follow-up period was 8.4% and 88.9% respectively (ANOVA mixed model; P . The mean percentage of restorations to total treatment rendered at baseline and 2nd follow-up was 3.9% and 13.0%, respectively (ANOVA mixed model; P . Ninety-nine percent of patients were satisfied with ART restorations, 96.6% willing to receive ART restoration again in future, and 94.9% willing to recommend ART treatment to their close relatives. Conclusion ART introduction in pilot government dental clinics raised the number of teeth saved by restorative care. Countrywide introduction of the ART approach in Tanzania is recommended.

    Adult male fathead minnows (Pimephales promelas) were exposed to effluent from the City of Boulder, Colorado wastewater treatment plant (WWTP) under controlled conditions in the field to determine if the effluent induced reproductive disruption in fish. Gonadal intersex and other evidence of reproductive disruption were previously identified in white suckers (Catostomus commersoni) in Boulder Creek downstream from this WWTP effluent outfall. Fish were exposed within a mobile flow-through exposure laboratory in July 2005 and August 2006 to WWTP effluent (EFF), Boulder Creek water (REF), or mixtures of EFF and REF for up to 28 days. Primary (sperm abundance) and secondary (nuptial tubercles and dorsal fat pads) sex characteristics were demasculinized within 14 days of exposure to 50% and 100% EFF. Vitellogenin was maximally elevated in both 50% and 100% EFF treatments within 7 days and significantly elevated by 25% EFF within 14 days. The steroidal estrogens 17??-estradiol, estrone, estriol, and 17??-ethynylestradiol, as well as estrogenic alkylphenols and bisphenol A were identified within the EFF treatments and not in the REF treatment. These results support the hypothesis that the reproductive disruption observed in this watershed is due to endocrine-active chemicals in the WWTP effluent. ?? 2011 Elsevier B.V.

    2013-12-01

    Full Text Available Aim: The current study was done to study the therapeutic effect of natural prostaglandin in treatment of canine pyometra. Materials and Methods: Seven bitches were treated with natural PGF2 á i.e. dinoprost tromethamine at the dose rate of 100 μg/kg body weight subcutaneously once daily for 7 days with supportive therapies. The physiological, haematological and biochemical parameters were studied before (0th day and after treatment (8th day. Therapeutic efficacy was assessed in terms of return of abnormal parameters to either normal or near normal value as compared to the untreated control group, intensity of side effects and post treatment reproductive status. Results: All physiological, haematological and biochemical parameters in the seven treated bitches returned to normal range at the end of treatment. The intensity of side effects was quite severe in the treatment group. Six bitches came to estrus within 2 months of treatment and out of them four conceived on subsequent mating. In rest three bitches there was recurrence of pyometra within 4 months of treatment. Conclusion: Though conception rate of recovered bitches is decreased when compared with that of normal healthy bitches still this treatment protocol can be used successfully in treatment of canine pyometra to conserve the breeding capability of bitches.

    Infection Zika virus is an emerging disease in the Americas region, which is caused by Zika virus (ZIKV), an arbovirus of the flavivirus genus. The ZIKV is transmitted by the bite of Aedes mosquitoes, both in urban and jungle area. After the mosquito bite, the disease symptoms usually appear after an incubation period of three to twelve days. The infection may be asymptomatic or presented with fever and not purulent conjunctivitis, headache, myalgia, arthralgia, asthenia, maculopapular rash, edema in lower limbs and, less frequently, retro-orbital pain, anorexia, vomiting, diarrhea or pain abdominal. Symptoms last for 4-7 days and are self-limiting. Neurological and autoimmune complications are rare. Since 2014 it has been detected native circulation of Zika virus in the Americas. So far, there is no specific antiviral treatment or effective vaccine, so it's giving priority symptomatic and supportive treatment for the acute phase and make an early diagnosis of atypical and severe forms.

    Full Text Available Objectives. To investigate the use of accelerometers to monitor change in physical activity in a childhood obesity treatment intervention. Methods. 28 children aged 7–13 taking part in “Families for Health” were asked to wear an accelerometer (Actigraph for 7-days, and complete an accompanying activity diary, at baseline, 3-months and 9-months. Interviews with 12 parents asked about research measurements. Results. Over 90% of children provided 4 days of accelerometer data, and around half of children provided 7 days. Adequately completed diaries were collected from 60% of children. Children partake in a wide range of physical activity which uniaxial monitors may undermonitor (cycling, nonmotorised scootering or overmonitor (trampolining. Two different cutoffs (4 METS or 3200 counts⋅min-1 for minutes spent in moderate and vigorous physical activity (MVPA yielded very different results, although reached the same conclusion regarding a lack of change in MVPA after the intervention. Some children were unwilling to wear accelerometers at school and during sport because they felt they put them at risk of stigma and bullying. Conclusion. Accelerometers are acceptable to a majority of children, although their use at school is problematic for some, but they may underestimate children's physical activity.

    2011-12-01

    Full Text Available Introduction: Trigger Finger (tenosynovitis stenosans is a specific, named disease from a group of repetitive strain injury (RSI diseases, caused by inflammation which results in difficulties during muscle contraction and weakened and painful tendon movement. It is common in the outpatient physical medicine and rehabilitation practice. The aim of our study was to evaluate the success of conservative treatment of Trigger Finger by local instillation of corticosteroids.Methods: The study was designed as an observational and open analysis of the results of conservative treatment of 45 patients. We used precise instillation of steroid anti-inflammatory antirheumatic drugs in the area of patho-anatomic, microtraumatic injuries of tendon and its sheath. Patients were evaluated before and after the treatment with 0 to 5 evaluation score scale. The data were analyzed using X2 test.Results: Most of the patients had evaluation score of 2, 3 and 4, before the treatment. After the treatment 10 (29% patients had achieved score 4 and 35 (71% patients had achieved score 5. All of the patients with score 5 had excellent working ability with full working capacity. Other patients had well-preserved working ability, which improved to excellent in maximum of 7 days.Conclusions: Conservative treatment of Trigger finger shows good therapeutic effects and taking into account the benefits, convenience and generally lower cost of conservative treatment for the patient, should be considered as an effective alternative to surgical treatment.

  5. Auricular point acupressure as an adjunct analgesic treatment for cancer patients: a feasibility study.

    Yeh, Chao Hsing; Chien, Lung-Chang; Chiang, Yi Chien; Ren, Dianxu; Suen, Lorna Kwai-Ping

    2015-06-01

    This study aimed (1) to examine the feasibility of an auricular point acupressure (APA) research protocol in terms of recruitment and for the assessment and management of pain and (2) to examine the potential APA analgesic effects for cancer patients. This study was a repeated-measures one-group design. Participants were recruited from the cancer center follow-up clinic affiliated with a large university hospital in the northeastern United States. Participants included 50 patients aged 55-87 years with a diagnosis of cancer. Participants received 7 days of APA treatment for their pain. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point on each ear. The study recruitment and retention rates were 92% and 91%, respectively. Importantly, the study found preliminary evidence for the analgesic effects of APA for cancer pain management. For example, by the end of the 7-day study, APA reduced pain intensity more than 55% for "worst pain" and about 57% for "average pain" and "pain intensity." Moreover, the use of pain medication was reduced during the APA treatment (e.g., 78% of patients [n = 39] took less pain medication than before the treatment). APA appears to be highly acceptable to patients with cancer-related pain. However, without a placebo control, we cannot draw conclusive evidence for the analgesic effect of APA for cancer patients. A sham group must be added to future studies to differentiate the true effects of APA from the possible psychological effects of the APA treatment. PMID:25439120

    The purpose of this study was to evaluate the influence of an erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser in the absence or presence of manual scaling and root planning (SRP) for the treatment of induced periodontitis in rats. Ligatures were placed in the subgingival region of the maxillary first molar. After a 7-day period, the ligatures were removed, and 40 rats were randomly divided into four groups (G), as follows: (GI) no treatment, (GII) scaling and root planning (SRP) with curettes, (GIII) Er,Cr:YSGG laser irradiation and (GIV) SRP with curettes followed by Er,Cr:YSGG laser irradiation. Seven and 30 days after the treatment, the animals were sacrificed and histologic, histometric and immunohistochemistry analyses were performed. All groups showed similar histopathological characteristics during the evaluation period. The histometric analysis was confirmed using Bonferroni and paired t tests. At 7 and 30 days, groups II, III and IV exhibited greater bone formation in the furcation area when compared to group I (p < 0.0001; p < 0.05). During the 7-day period, the groups irradiated with the laser (III and IV) showed a statistically larger new bone area than the group treated with SRP (II) (p < 0.01). Immunohistochemistry analysis revealed that the control group exhibited a higher expression of tartrate-resistant acid phosphatase (TRAP) and the receptor activator of nuclear factor κΒ ligand (RANKL) when compared to groups II, III and IV (p < 0.05). All treatments were able to reduce the inflammatory processes, consequently enabling the repair of periodontal tissues. The results achieved with the application of the Er,Cr:YSGG laser suggest that this laser can stimulate greater bone formation, especially over a shorter period of time. PMID:24477391

    Objective: To investigate the surgical treatment for patients with multiple injuries in ICU.Methods: Clinical data of 163 multiple injury patients admitted to ICU of our hospital from January 2006 to January 2009 were retrospectively studied, including 118 males and 45 females, with the mean age of 36.2 years (range, 5-67 years). The injury regions included head and neck (29 cases),face (32 cases), chest (89 cases), abdomen (77 cases), pelvis and limbs (91 cases) and body surface (83 cases). There were 57 cases combined with shock. ISS values varied from 10 to 54, 18.42 on average. Patients received surgical treatments in ICU within respectively 24 hours (10 cases), 24-48 hours (8 cases), 3-7 days (7 cases) and 8-14 days (23 cases).Results: Forthe 163 patients, the duration of ICU stay ranged from 2 to 29 days, with the average value of 7.56 days. Among them, 143 were cured (87.73%), 11 died in the hospital (6.75%) due to severe hemorrhagic shock (6 cases),craniocerebral injury (3 cases) and multiple organ failure (2 cases), and 9 died after voluntarily discharging from hospital (5.52%). The total mortality rate was 12.27%.Conclusions: The damage control principle should be followed when multiple injury patients are resuscitated in ICU. Surgical treatment strategies include actively controlling hemorrhage, treating the previously missed injuries and related wounds or surgical complications and performing planned staging operations.

  8. Minimally Invasive Surgical Treatment of Acute Epidural Hematoma: Case Series

    2016-01-01

    Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL); postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes); no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n = 1), 41–60 (n = 1), and >60 (n = 55); scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy. PMID:27144170

  9. Hyperbaric oxygen treatment promotes neural stem cell proliferation in the subventricular zone of neonatal rats with hypoxic-ischemic brain damage

    2013-01-01

    Hyperbaric oxygen therapy for the treatment of neonatal hypoxic-ischemic brain damage has been used clinically for many years, but its effectiveness remains controversial. In addition, the mechanism of this potential neuroprotective effect remains unclear. This study aimed to investigate the influence of hyperbaric oxygen on the proliferation of neural stem cells in the subventricular zone of neonatal Sprague-Dawley rats (7 days old) subjected to hypoxic-ischemic brain damage. Six hours after modeling, rats were treated with hyperbaric oxygen once daily for 7 days. Immunohistochemistry revealed that the number of 5-bromo-2′-deoxyuridine positive and nestin positive cells in the subventricular zone of neonatal rats increased at day 3 after hypoxic-ischemic brain damage and peaked at day 5. After hyperbaric oxygen treatment, the number of 5-bromo-2′- deoxyuridine positive and nestin positive cells began to increase at day 1, and was significantly higher than that in normal rats and model rats until day 21. Hematoxylin-eosin staining showed that hyperbaric oxygen treatment could attenuate pathological changes to brain tissue in neonatal rats, and reduce the number of degenerating and necrotic nerve cells. Our experimental findings indicate that hyperbaric oxygen treatment enhances the proliferation of neural stem cells in the subventricular zone of neonatal rats with hypoxic-ischemic brain damage, and has therapeutic potential for promoting neurological recovery following brain injury.

    Full Text Available Quality of life on Earth in the future will largely depend on the amount of safe water. As the most fundamental source of life, water is relentlessly consumed and polluted. To halt this trend, many countries are taking extensive measures and investing substantial resources in order to stop the contamination of water and return at least tolerably good water quality to nature. The goal of water purification is to obtain clean water with the sewage sludge as a by-product. Clean water is returned to nature, and further treatment of sludge may be subject to other procedures. The conclusion of this paper is simple. The procedure with purified water is easily achievable, purified water is discharged into rivers, lakes and seas, but the problem of further treatment of sludge remains. This paper presents the basic methods of wastewater treatment and procedures for processing the products from contaminated water. The paper can serve as a basis for further elaboration. Water Pollution In order to ensure normal life of living creatures, the water in which they live or the water they use must have a natural chemical composition and natural features. When, as a result of human activities, the chemical composition of water and the ratio of its chemical elements significantly change, we say that water is polluted. When the pollutants come from industrial plants, we are talking about industrial wastewater, and when they come from households and urban areas, we are talking about municipal wastewater. Both contain a huge amount of pollutants that eventually end up in rivers. Then, thousands of defenseless birds, fish and other animals suffer, and environmental consequences become immeasurable. In addition, the waste fed to the water often ends up in the bodies of marine animals, so they can return to us as food. Thermal water pollution also has multiple effects on the changes in the wildlife composition of aquatic ecosystems. Polluted water can be purified by

  13. Nonoperative biological treatment approach for partial Achilles tendon lesion.

    Filardo, Giuseppe; Presti, Mirco Lo; Kon, Elizaveta; Marcacci, Maurilio

    2010-02-01

    Tendon injuries, especially those of the Achilles tendon, are major concerns in sports medicine. The clinical presentation can be acute or chronic and the pathologic findings can range from peritendonitis to full-thickness tendon rupture. Nonsurgical treatment is not always successful; in particular, significant partial ruptures seem to respond poorly to conservative measures and do not improve with time. Surgery is most often considered the favored treatment option for this kind of lesion to obtain pain relief and full functionality with long-standing effects.This article describes a case of a partial tear of the Achilles tendon in a 34-year-old competitive athlete where surgical treatment was avoided in favor of a new biological approach. We applied autologous platelet growth factors through multiple platelet-rich plasma injections; approximately 6.5 billion platelets were injected into the lesion 3 times, 7 days apart. The treatment with platelet-rich plasma and a progressive rehabilitation program allowed the patient to play for 20 minutes in a basketball game 64 days after the trauma and in a full game 75 days after the trauma. To date, 18 months later, he has participated regularly in all the season's games and received no further treatment for his tendon.The fast tissue repair, confirmed by magnetic resonance and ultrasound imaging, allowed a swift return to full functionality and competitive sports activity, suggesting a possible role of platelet growth factors in promoting rapid tendon healing with high-quality tissue. This biological approach may represent a less-invasive therapeutic option even in cases where severe tendon lesions are candidates for surgical treatment. PMID:20192152

    1983-12-01

    The present study was carried out to measure lipid and protein levels in serum of healthy women during treatment with a new oral contraceptive combination containing 0.075 mg desogestrel (Org 2969, 17 alpha-ethinyl-18-methyl-11-methylene-4-estren-17-ol) plus 0.050 mg ethinyloestradiol per tablet. All 30 volunteers took 1 tablet daily for 21 consecutive days, followed by a tablet-free period of 7 days. Treatment lasted 3 months. At the end of treatment serum total cholesterol had increased by 0.26 mmol/l (5.0%), high-density lipoprotein-cholesterol by 0.22 mmol/l (15.2%) and triglycerides by 0.43 mmol/l (50%); the calculated low-density lipoprotein cholesterol had decreased by 0.16 mmol/l (4.9%). All lipid concentrations had returned to initial levels 2 months after treatment stopped. After 3 months treatment serum ceruloplasmin, cortisol-binding globulin capacity, sex-hormone-binding globulin capacity and thyroxine-binding globulin had significantly increased by 85.2, 133, 206 and 101%, respectively. All protein levels returned to normal 2 months after treatment stopped. The relationship between serum lipids and hormone-binding proteins has been discussed, as well as the significance of the high-density lipoprotein level with regard to contraceptive treatment.

    2016-01-01

    The authors assessed efficacy of regional intraosseous administration of urokinase medac in comprehensive treatment of patients with complicated forms of diabetic foot syndrome by means of analysing therapeutic results in a total of 65 patients presenting with pyonecrotic complications of diabetic foot. The patients were subdivided into 2 groups. The control group was composed of 35 patients receiving basic therapy. The study group comprised 30 patients subjected to comprehensive treatment including regional intraosseous (into the heel bone of the affected limb) administration of urokinase medac at a dose of 100 thousand IU for 5 days. Efficacy of treatment was evaluated by the course of the wound process, indices of haemostasis, free radical oxidation, results of surgical treatment. In patients of the Study Group the terms of wound purification from pyonecrotic masses amounted to 9.8±0.3 days, which was by 4.7 days less than in the Control Group patients (pGroup patients as early as on day 5 of treatment demonstrated shifts towards normocoagulation. In the Control Group by day 22 of treatment, the level of malonic dialdehyde decreased by 18.5%, the index of catalase activity increased by 24.6% (pGroup the level of malonic dialdehyde decreased by 42.6% and catalase activity increased by 69.4% (pblood and the level of free-radical lipid oxidation, stimulation of regenerative processes, as well as improvement of outcomes of surgical treatment.

  16. Gametocytogenesis Following Drug Treatment of Plasmodium Falciparum in an Area of Seasonal Transmission in Sudan

    We monitored post-treatment Plasmodium falciparum among patients treated with chloroquine (CQ) and pyrimethamine-sulfadoxine (PS) in a village in eastern Sudan. Parasites were examined on day zero (pre-treatment), day 7, day 14 and day 21 (post-treatment) during the transmission season. A further sample was taken two months later (Day 80) at the start of the dry season. Asexual forms and gametocytes were detected by microscopy and reverse transcriptase polymerase chain reaction (RT-PCR) to detect expression of a gametocyte-specific protein pfg377. Gametocyte carriage, as revealed by microscopy, increased significantly following CQ and PS treatment reaching a maximum between days 7 and 14. When measured by RT-PCR, however, there was no significant difference in gametocyte rate between day 0 and day 7 or 14. RT-PCR gametocyte rates dropped dramatically by day 80 post-treatment but were still 33% and 8% in the CQ and PS treated group at this time. Alleles associated with drug resistance of P. falciparum to chloroquine (the chloroquine resistance transporter, pfcrt, and multi-drug resistance, pfmdr-1) and pyrimethamine (dihydrofolate reductase, dhfr) were at high frequency at the beginning of treatment and increased further through time under both drug treatments. Infections with drug-resistant parasites tended to have higher gametocyte prevalence than drug-sensitive infections.

  17. Paroxetine treatment, following behavioral suppression of PTSD-like symptoms in mice, prevents relapse by activating the infralimbic cortex.

    2016-02-01

    Clinical studies have shown that post-traumatic stress disorder (PTSD) remission, induced by selective serotonin reuptake inhibitor (SSRI) treatment, is associated with increased prefrontal activation during post-treatment symptom provocation. Other studies have shown that continuation SSRI treatment after remitting from PTSD reduces the rate of relapse. The aim of the present preclinical study was to investigate the relationship between post-treatment prefrontal changes and PTSD relapse prevention. Avoidance conditioning (with a 1.5-mA foot-shock), avoidance extinction and a trauma priming exposure (with a 0.3-mA foot-shock) were used in mice to induce, suppress and reactivate PTSD-like symptoms (including avoidance, fear sensitization, enhanced contextual fear, and anxiety-like behavior), respectively. Paroxetine, injected at 8 mg/kg/day (7 days), was used as SSRI treatment. PTSD-like symptoms were present for at least 30 days and resistant to paroxetine treatment. However, after extinction training (suppressing all PTSD-like symptoms), paroxetine treatment prevented symptom reactivation. Paroxetine treatment also induced infralimbic neuronal activation. However, infralimbic functional tetrodotoxin inactivation abolished the preventive effect of paroxetine treatment on symptom reactivation. The data reveal a potential ability of treatments inducing infralimbic activation to provide prophylactic protection against PTSD relapse. PMID:26706692

    Cerebral malaria is caused by Plasmodium falciparum. Atorvastatin (AVA) is a pentasubstituted pyrrole, which has been tested as an adjuvant in the treatment of cerebral malaria. Herein, a new class of hybrids of AVA and aminoquinolines (primaquine and chloroquine derivatives) has been synthesized. The quinolinic moiety was connected to the pentasubstituted pyrrole from AVA by a linker group (CH2)n=2-4 units. The activity of the compounds increased with the size of the carbons chain. Compound with n=4 and 7-chloroquinolinyl has displayed better activity (IC50=0.40μM) than chloroquine. The primaquine derivative showed IC50=1.41μM, being less toxic and more active than primaquine.

  19. Diet-related greenhouse gas emissions assessed by a food frequency questionnaire and validated using 7-day weighed food records

    Sjörs, Camilla; Raposo, Sara E; Sjölander, Arvid; Bälter, Olle; Hedenus, Fredrik; Bälter, Katarina

    2016-01-01

    Background: The current food system generates about 25 % of total greenhouse gas emissions (GHGE), including deforestation, and thereby substantially contributes to the warming of the earth’s surface. To understand the association between food and nutrient intake and GHGE, we therefore need valid methods to assess diet-related GHGE in observational studies. Methods: Life cycle assessment (LCA) studies assess the environmental impact of different food items. We linked LCA data expressed as kg ...

These improvements include increased peripheral insulin sensitivity and responsiveness as well as enhanced suppression of hepatic glucose production.......The objectives of this study were to determine whether 1) the improvement in insulin action induced by short-term exercise training in patients with type 2 diabetes is due to an improvement in insulin sensitivity, an improvement in insulin responsiveness, or a combination of improved insulin...

  1. Survey of the vestibulum, and behavior of xenopus laevis larvae developed during a 7-days space flight

    Briegleb, W.; Neubert, J.; Schatz, A.; Klein, T.; Kruse, B.

    Aquatic animals have almost no body weight related proprioception for spatial orientation. Xenopus larvae, like fish, maintain their attitude in water by continuous correction with their fin(s). For these reasons a special performance of the equilibrium system compared to terrestrial animals is necessary. Evidently fish therefore have more compact (dense) otoliths; Xenopus larvae have less dense otolith (membranes) similar to land vertebrates; but their sacculus-otoliths are vertically positioned, which also may lead to a higher g-sensitivity. For plausibility reasons gravity should influence the embryonic development of gravity receptors. Yet, evaluations of photographs taken from the surface of cut deep-frozen objects by incident light show no aberration of the shape of the whole vestibulum and of the shape, density, size and position of the otolith membrane in larvae developed under near-zero g (NEXPA-BW-STATEX in D1-Mission). The further evaluation of the ``weightless-larvae'' revealed a probably not yet described statolith-like formation in the dorsal wall of the vestibulum. In the weightless larvae this formation outnumbers, also qualitatively, strongly the 1-g controls. An extra result is the lack of striking effects of cosmic radiation on the embryonic development of the flown Xenopus eggs. The swimming behavior of the larvae which was observed about one hour after landing of the Space Shuttle showed a typical anomaly (loop swimming), which is known from larvae developed on the clinostat or from fish flown aboard Apollo capsules.

  2. Decrease of contractile properties and transversal stiffness of single fibers in human soleus after 7-day “dry” immersion

    Ogneva, I. V.; Ponomareva, E. V.; Kartashkina, N. L.; Altaeva, E. G.; Fokina, N. M.; Kurushin, V. A.; Kozlovskaya, I. B.; Shenkman, B. S.

    2011-05-01

    The simulation model of "dry" immersion was used to evaluate the effects of plantar mechanical stimulation (PMS) and high frequency electromyostimulation (EMS) on the mechanical properties of human soleus fibers under the conditions of gravitational unloading. We examined contractile properties of single fibers by means of tensometry, transversal stiffness of sarcolemma and different areas of the contractile apparatus by means of atomic force microscopy. It was shown that there is a reduction of transversal stiffness in single muscle fibers under hypogravitational conditions. Application of different countermeasures could compensate this effect. Meanwhile pneumostimulation and electro stimulation act in quite different way. Therefore, pneumostimulation seems to be more effective. The data obtained can be considered as the evidence of the fact that such countermeasures as PMS and electromyostimulation influence on muscle fibers in quite different ways and PMS efficiency is likely to be higher. On the basis of our experimental data on transverse stiffness of mechanotransductional nodes and the contractile apparatus, we can assume that support stimulation allows prevention of destructive processes in muscle fibers. Electrostimulation seems to stimulate contractile activity only without suppression of impairment of the fiber mechanical properties.

    2013-12-01

    Full Text Available Objectives: This study evaluated the influence of different exposure times to saliva in situ in comparison with an antioxidant treatment on composite resin bond strength to human enamel restored after tooth bleaching. Material and Methods: Forty human teeth specimens measuring 5x5 mm were prepared and randomly allocated into 5 groups with 8 specimens each: Gct (control group, restored on unbleached enamel; Gbl (restored immediately after bleaching; Gsa (bleached, treated with 10% sodium ascorbate gel for 60 min and restored; G7d (bleached, exposed to saliva in situ for 7 days and restored; and G14d (bleached, exposed to saliva in situ for 14 days and restored. Restored samples were cut into 0.8 mm2 sticks that were tested in microtensile. Specimens were microscopically analyzed and failure modes were classified as adhesive, cohesive, or mixed. Pretest and cohesive failures were not considered in the statistical analysis, which was performed with one-way ANOVA and Tukey's post-hoc test (α=0.05, with the dental specimen considered as the experimental unit. Results: Mean bond strength results found for Gbl in comparison with Gct indicated that bleaching significantly reduced enamel adhesiveness (P0.05. Bond strength found for G14d was significantly higher than for Gsa (P<0.01. Fractures modes were predominantly of a mixed type. Conclusions: Bonding strength to bleached enamel was immediately restored with the application of sodium ascorbate and exposure to human saliva in situ for at least 7 days. Best results were obtained with exposure to human saliva in situ for 14 days. Treatment with sodium ascorbate gel for 60 min may be recommended in cases patients cannot wait for at least 7 days for adhesive techniques to be performed.

    Janssen, J P; van Mourik, J; Cuesta Valentin, M; Sutedja, G; Gigengack, K; Postmus, P E

    1994-07-01

    Thoracoscopy for spontaneous pneumothorax has been performed over the years by many pulmonologists. The aim of the procedure was merely diagnostic: the detection of blebs and bullae. Therapeutic modalities were restricted to chemical pleurodesis. The development of videothoracoscopy has made more complex interventions, such as bullectomy possible. A protocol for videothoracoscopic treatment of spontaneous pneumothorax, with all treatment modalities in one session, has been developed. All patients with spontaneous pneumothorax underwent videothoracoscopy under general anaesthesia with double lumen tube intubation. If no abnormalities were found on the visceral pleura, talc pleurodesis was performed. Small lesions, blebs or bullae 2 cm, thoracoscopic resection with an EndoGIA stapling device was performed, followed by scarification, i.e. electrocoagulation, of the parietal pleura. In 43 patients, 44 procedures were performed. In 15 cases (34%) no blebs or bullae were found. In 6 cases (14%) only blebs 2 cm were found. In 21 out of 44 cases (48%), talc pleurodesis was performed, and in 23 cases (52%) bullectomy was performed. No major complication occurred. The average hospital stay was 5.7 days after talc pleurodesis and 6.0 days after bullectomy. There were 2 recurrences (5%) after a follow-up of at least 18 months. In conclusion, the use of videothoracoscopy in spontaneous pneumothorax makes it possible to continue a diagnostic procedure as a therapeutic session.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7925907

  7. Effect of alkali treatment on surface morphology of titanium

    Alkali and heat treatments were first introduced by Kim et al. to prepare a bioactive surface on titanium. This method has been proven very effective and widely used in other studies to promote titanium osteointegration. This study aims to investigate further the effect of alkali treatment on surface morphology of high purity titanium. High purity titanium foils were immersed in NaOH aqueous solutions of 0.5 M, 5 M and 15 M at 60°C and 80 °C for 1, 3 and 7 days. The surface morphology was examined using Field Emission Scanning Electron Microscope (FESEM). The obtained phases were analysed using Fourier Transform Infrared Spectroscopy (FTIR) in the spectra range of 4000-600 cm−1 at 4 cm−1 resolution and 50 scans. At the same soaking temperature and soaking time, a thicker porous network was observed with increasing concentration of NaOH. At the same soaking temperature, a much porous structure was observed with increasing soaking time. At constant alkali concentration, more homogenously distributed porous surface structure was observed with increasing soaking temperature

    Full Text Available Aim. To evaluate antianginal and antiischemic efficiency of nebivolol in patients with stable angina pectoris.Material and methods. 100 patients with ischemic heart disease showing stable exertional angina pectoris and having no contraindications to beta-blockers were studied. After 5-7 days of control period 50 randomly selected patients began to take nebivolol in initial dose of 5mg once daily and 50 patients started to take metoprolol in initial dose of 50 mg twice daily. Duration of treatment was 8 weeks. Efficiency of treatment was assessed according to the results of control treadmill assessment and control daily ECG monitoring.Results. 56-day therapy with nebivolol at a dose of 7,5 mg per day results in increase in duration of treadmill test before angina or ST depression (p<0.05. Antianginal and antiischemic effect of nebivolol 7.5 mg once daily is rather similar with that of metoprolol in average daily dose of 175 mg. Nebivolol compared to metoprolol significantly (p<0.05 more effectively reduces the number of silent myocardial ischemia.Conclusion. Nebivolol is an efficient antianginal and antiischemic drug for patients with stable exertional angina pectoris.

  9. Interventional treatment of un-ruptured tubal pregnancy

    Objective: To discuss some concept about interventional treatment of tubal pregnancy. Methods: The procedure of trans-vaginal tubal intra-gestational SAC injection (IGSI) or percutaneous intra-utero-arterial infusion (IUAI) was selected for treatment of 40 patients with un-ruptured tubal pregnancy. Methotrexate (MTX), Rosch-Thurmoud fallopian tube catheterization set, and the general angiographic catheters of 4.1-5.0 F were used for the procedure. Ultrasound and urine beta-hCG were the main indexes monitoring the therapeutic effects. Results: 12 of 40 patients underwent a total of 15 IGSI. Of these, 3 patients required a second injection; 28 of 40 cases were treated with IUAI. The total successful rate of termination of ectopic pregnancy was 97.5%, the mean resolution time for reduction of beta-hCG concentration was 11.7 days (range 4-28), the range of menstruation recovery time was 7-45 days. Conclusion: The interventional therapy for tubal pregnancy will be more widely applied, on the basis of a better understanding about the pathology, characteristics of embryonic sac development and blood supply, the regular change of concentration of serum and urine hCG in tubal pregnancy

    For a proangiogenic therapy to be successful, it must promote the development of mature vasculature for rapid reperfusion of ischemic tissue. Whole growth factor, stem cell, and gene therapies have yet to achieve the clinical success needed to become FDA-approved revascularization therapies. Herein, we characterize a biodegradable peptide-based scaffold engineered to mimic VEGF and self-assemble into a nanofibrous, thixotropic hydrogel, SLanc. We found that this injectable hydrogel was rapidly infiltrated by host cells and could be degraded while promoting the generation of neovessels. In mice with induced hind limb ischemia, this synthetic peptide scaffold promoted angiogenesis and ischemic tissue recovery, as shown by Doppler-quantified limb perfusion and a treadmill endurance test. Thirteen-month-old mice showed significant recovery within 7 days of treatment. Biodistribution studies in healthy mice showed that the hydrogel is safe when administered intramuscularly, subcutaneously, or intravenously. These preclinical studies help establish the efficacy of this treatment for peripheral artery disease due to diminished microvascular perfusion, a necessary step before clinical translation. This peptide-based approach eliminates the need for cell transplantation or viral gene transfection (therapies currently being assessed in clinical trials) and could be a more effective regenerative medicine approach to microvascular tissue engineering.

  11. Clinical observation of associated treatment for Graves' disease with traditional chinese medicine and 131I

    To investigate the method and curative effect of associated treatment for Graves Disease (GD) with traditional Chinese medicine and 131I. 100 patients with GD were randomly divided into two groups, the patients in group A was only given 131I treatment and the patients in group B was given traditional Chinese medicine (Shimaiqing Fluid, 3 times of 20 mL per day for 40 days) after 7 days of 131I treatment. The serum FT3, FT4 and TSH were measured before and 30 and 90 days after treatment. 8 cardinal symptoms were selected and Kupperman 4-grade grading method was used to assess the remission of the disease. The Results showed that the symptoms of patients in group B were improved ahead of time, and pass through the FT3 and FT4 rebound elevation period safely after one month of 131I treatment. The symptoms of patients in group A after 30 days treatment were more serious than that of before treatment, the levels of serum FT3 and FT4 were both higher than those of before treatment. The symptoms of patients in group B after 90 days treatment were improved significantly, and the levels of serum FT3, FT4 and TSH were in normal value. The clinical symptoms of patients in group A were improved, but the levels of serum FT3 and FT4 were lower and TSH was higher than normal value. The curative effect in group B was better than that in group A, the patients passed through the high risk period safely after 30 days treatment, and the hypothyroidism rate was decreased after 90 days treatment. The Shimaiqing Fluid is a nontoxic and safe medicine, and it may be widely used in clinical treatment for patients with GD. (authors)

    Full Text Available Introduction. Laparoscopic Heller­Dor operation, a standard method in the treatment of achalasia, has been performed at the Center for Esophageal Surgery of the First Surgical Clinic since April 2006. Objective. The aim of this study was to present this surgical procedure and initial experiences after 36 consecutive laparoscopic Heller­Dor operations. Methods. This partly retrospective, partly prospective study presented our results after laparoscopic Heller­Dor operation (presentation of the treatment method. We performed a standard anterior esophagocardioymiotomy, without releasing the posterior aspect of the cardia, and anterior partial fundoplication. The type and severity of symptoms and their duration were evaluated based on questionnaires fulfilled by patients. The diagnosis was made based on radiological, endoscopic and manometric findings. Laparoscopic surgery as the method of treatment was evaluated based on the duration of surgery, intra­ and postoperative complications, time interval until the initiation of oral feeding, length of hospital stay, need for additional therapeutic measures after the operation and effect of surgery on the severity of symptoms. Results. Preopereratively, dysphagia was the predominant symptom in all patients, while regurgitation was much lower (44%. The average duration of operation was 127 minutes. Postoperative hospitalization lasted on the average 5.7 days. From 36 treated patients, 34 (94.4% considered that the effect of treatment was good or excellent. Postoperative dysphagia was present in two patients (5.6% and was successfully solved by balloon dilatation. Conclusion. Laparoscopic Heller­Dor operation is an effective and safe surgical procedure in resolving symptoms of achalasia and today presents the method of the first choice in the treatment of this disease.

    This study evaluated the effectiveness of antimicrobial photodynamic therapy (aPDT) in the treatment of oral candidiasis in a murine model using Photodithazine® (PDZ). This model of oral candidiasis was developed to allow the monitoring of the infection and the establishment of the aPDT treatment. Six-week-old female mice were immunosuppressed and inoculated with C. albicans to induce oral candidiasis. PDZ-mediated aPDT and nystatin treatment were carried out for 5 consecutive days with one application per day. The macroscopic evaluation of oral lesions was performed. After each treatment, the tongue was swabbed to recover C. albicans cells. Viable colonies were quantified and the number of CFU/ml determined. The animals were sacrificed 24 hours and 7 days after treatment and the tongues were surgically removed for histological analysis and analysis of inflammatory cytokines expression (IL-1, TNF-α and IL-6) by RT-qPCR. Data were analyzed by two-way ANOVA. PDZ-mediated aPDT was as effective as Nystatin (NYS group) in the inactivation of C. albicans, reducing 3 and 3.2 logs10 respectively, 24 h after treatment (pcandidiasis. PMID:27253525

  14. Clinical management of carbamazepine intoxication during anti-tubercular treatment: a case report

    Massimo Calderazzo

    2015-06-01

    Full Text Available We describe a 67-year-old man with medical history of focal post-stroke seizure and type 2 diabetes mellitus treated with carbamazepine, clobazam, gliclazide, insulin glargine, and omeprazole we visited for the onset in the last 7 days of asthenia, cough with mucus, breathing difficulty, chest pain, and weight loss. After clinical and laboratory tests, pulmonary tuberculosis was diagnosed, and a treatment with isoniazid, ethambutol, pyrazinamide rifampicin, and pyridoxine was started. Therapeutic drug monitoring of tuberculosis treatment documented that all drugs were in normal therapeutic range. Four days after the beginning of the treatment, we documented the improvement of fever, and three days later the patient showed sleepiness, visual disorder and asthenia. Clinical and pharmacological evaluation suggested a carbamazepine toxicity probably related to a drug interaction (Drug Interaction Probability Scale score = 6. The impossibility to switch carbamazepine for another antiepileptic drug, due to a resistant form of seizure, induced the discontinuation of tuberculosis treatment, resulting in the normalization of serum carbamazepine levels in one day (10 µg/ml and in the worsening of fever, requiring a new clinical and pharmacological evaluation. The titration dosage of carbamazepine and its therapeutic drug monitoring allowed to continue the treatment with both antitubercular drugs and carbamazepine, without the development of adverse drug reactions. To date, tuberculosis treatment was stopped and clinical evaluation, radiology and microbiology assays documented the absence of tubercular infection and no seizures appeared (carbamazepine dosage 800 mg/bid; serum levels 9.5 µg/ml.

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

    Leah J McGrath

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

  17. Radwaste treatment

    In this part creation of radioactive wastes in Bohunice V-1 and V-2 NPPs and in A-1 NPP during decommissioning process as well as its treatment is described. On January 1996, radioactive waste repository in Mochovce was transferred to the administration of the newly established subsidiary SE-VYZ. During 1996 the repository operator began implementation of requirements contained in the Resolution of Nuclear Regulatory Authority of the Slovak Republic (NRA SR) of the beginning of 1995. Currently the works concentrate mainly on supplementary engineering and geological survey and preparation of a principal change in the drainage system, as well as vault roofing. NRA SR is involved in most of the negotiations on further proceeding, where it makes contributions by its opinions; through, that it controls to what extent the activity at the repository is in compliance with the Resolution of NRA SR as to the Preliminary safety report of the repository. Two inspections were made at the repository in the spring: the first concentrated on consequences of erosion movement of the outer slopes of the repository, the second one dealt with the overall inventory of activities following up the Resolution of NRA SR. As a result of a significant acceleration of work in the last thee months of 1966, NRA SR started to apply regular inspections at the site made at least once a week by the site inspector. The main purpose of these inspections is to supervise the quality of work being performed

    Full Text Available Utilization of jatropha seed meal as a feed ingredient is limited by the presence of several anti nutritive and toxic compounds in the seed meal. The aim of this research is to evaluate feeding of jatropha seed meal detoxified using fermentation by two fungi and rumen microbes (as biological detoxification and using a combination of chemical and physical treatments on broiler performance. One hundred seventy five chicks (7 days old were used and were divided into 5 treatments in 7 replications and each replication in one cage consisted of 5 chicks. R1 was control feed (K without jatropha seed meal., 2 R2 was feed with 4% of Jatropha seed meal fermented by Neurosphora sitophila (FNS, R3 was feed with 4% of Jatropha seed meal fermented by Aspergillus oryzae (FAS, R4 was feed with 4% of Jatropha seed meal fermented by rumen microbes and R5 with 4% of Jatropha seed meal treated by autoclaved, refluxed by hexane and soaked in methanol (OEHM. Treated feed was given for 14 days at the end of the feeding treatment, two chickens from each replication were slaughtered and organ weights were recorded. Body weight of chicken and feed conversion ratio were calculated. The rest of the chicken was fed commercial feed for the next 7 days (recovery periode. Chicken mortality was almost 0% but 1 chicken from FAS treatment died at the recovery period. Feed consumption was lower at fermented jatropha seed meal than control (K or OEHM, resulted in lower body weight of chicken. The abdomen fat weight and organ weights especially pancreas or spleen resulted from treatment with jatropha were much lower than that of K. In the recovery period, body weight of chicken in the OEHM treatment was almost similar from that of control chicken. In conclusion, biological detoxification on BBJ was able to reduce chicken mortality but could not improve the daily gain higher than control treatment. The best method to detoxify jatropha seed meal was the combination of physical and

  19. Sequential UASB and dual media packed-bed reactors for domestic wastewater treatment - experiment and simulation.

    Rodríguez-Gómez, Raúl; Renman, Gunno

    2016-01-01

    A wastewater treatment system composed of an upflow anaerobic sludge blanket (UASB) reactor followed by a packed-bed reactor (PBR) filled with Sorbulite(®) and Polonite(®) filter material was tested in a laboratory bench-scale experiment. The system was operated for 50 weeks and achieved very efficient total phosphorus (P) removal (99%), 7-day biochemical oxygen demand removal (99%) and pathogenic bacteria reduction (99%). However, total nitrogen was only moderately reduced in the system (40%). A model focusing on simulation of organic material, solids and size of granules was then implemented and validated for the UASB reactor. Good agreement between the simulated and measured results demonstrated the capacity of the model to predict the behaviour of solids and chemical oxygen demand, which is critical for successful P removal and recovery in the PBR.

    Kromann-Andersen, B; Sommer, P; Pers, C; Larsen, V; Rasmussen, F

    1988-09-01

    In a double-blind, double-dummy study 61 patients with structural or functional abnormalities of the urinary tract and verified infection were treated for 7 days with ofloxacin 100 mg bd or ciprofloxacin 250 mg bd by mouth. Of 62 isolated strains none was resistant to ofloxacin or ciprofloxacin in vitro. Nineteen patients (63%) in both groups were free from infection ten days after therapy. Clinical resolution of symptoms occurred in 83% in the ofloxacin group and 68% in the ciprofloxacin group. Adverse reactions were reported in four patients (6.5%), two with skin rash, one with gastrointestinal disturbance and one with influenza-like symptoms. This study demonstrates that ofloxacin and ciprofloxacin are effective in the treatment of complicated lower urinary tract infection. PMID:3182457

    XIE Wenyu; ZHONG Li; CHEN Jianjun

    2007-01-01

    The slightly polluted wastewater from oil refinery contains some COD, oil pollutants and suspended solids (SS). A small-scale fixed film biological aerated filter (BAF) process was used to treat the wastewater. The influences of hydraulic retention time (HRT), air/water volume flow ratio and backwashing cycle on treatment efficiencies were investigated. The wastewater was treated by the BAF process under optimal conditions: the HRT of backwashing cycle of every 4-7 days. The results showed that the average removal efficiency of COD, oil pollutants and SS was 84.5%, 94.0% and 83.4%, respectively. And the average effluent concentration of COD, oil pollutants and SS was 12.5, 0.27, 14.5the BAF process is a suitable and highly efficient method to treat the wastewater.

    1999-01-01

    To study the possible use of probiotics in fish farming, we evaluated the in vitro and in vivo antagonism of antibacterial strain Pseudomonas fluorescens strain AH2 against the fish- pathogenic bacterium Vibrio anguillarum. As iron is important in virulence and bacterial interactions, the effect of....... fluorescens AH2 inhibited the growth of V. anguillarum during coculture, independently of the iron concentration, when the initial count of the antagonist was 100 to 1,000 times greater that of the fish pathogen. These in vitro results were successfully repeated in vivo. A probiotic effect in vivo was tested...... probiotic treatment resulted in a 46% reduction of calculated accumulated mortality; accumulated mortality was 25% after 7 days at 12 degrees C in the probiotic-treated fish, whereas mortality was 47% in fish not treated with the probiont...

  3. Performance of vegetated and non-vegetated vertical flow reed beds in the treatment of diluted leachate.

    De Feo, Giovanni

    2007-06-01

    This study was undertaken to investigate the behaviour of a vertical flow reed bed system with 3 kind of wastewaters (W1, W2 and W3) and for two hydraulic retention times (3 and 7 days) as well as to assess the role of Phragmites Australis in constructed wetland treatment processes. The adopted batch experimental system consisted of six vertical flow filters, filled with granular media and planted with reeds. For each vegetated reactor there was a correspondent blank in order to make a comparison. Wastewaters were obtained mixing tap water, MSW landfill leachate and activated sludge in different percentages. W1, W2 and W3 were designed in order to reproduce treated or untreated wastewaters not in compliance with legislation in force (Directive 91/271/EEC), with increasing level of NH4+-N from W1 (16.3 mg/L) to W3 (76.0 mg/L). In average terms, 3 days was sufficient for W1 and W2 to face the compliance limits; while, for W3 even 7 days was not sufficient to respect the compliance limit for ammonia nitrogen (1.4 times greater). The obtained results shown that the vegetation played an essential role especially in the removal of nitrogen: for the wastewater with the highest loads the contribution of reeds in the removal of nitrogen was greater than that of biofiltration processes. The contribution of the vegetation was also detectable in the removal of orthophosphate, but with minus efficiency. PMID:17558782

    The aim of this study was to evaluate the effects of the use of a high-power gallium-aluminum-arsenide diode laser (GaAlAs; 808 nm, 1 W, 20 s, 20 Hz, 10 J) alone or as adjunctive therapy to scaling and root planing in the treatment of induced periodontitis in rats. Periodontitis was induced by placing a ligature around the mandibular first molar of 60 rats. After 7 days, the ligature was removed and the animals were divided into four groups as follows: C (control), no periodontal treatment; SRP, scaling and root planing (SRP); DL, diode laser (DL) irradiation treatment; and SRP/DL, both SRP and DL irradiation treatment. Five animals from each group were euthanized at 7, 15, and 30 days posttreatment. The effectiveness of the treatments was evaluated in the furcation area using histopathological analysis, histometric analysis of alveolar bone loss (ABL), and immunohistochemical detection of tartrate-resistant acid phosphatase (TRAP), runt-related transcription factor 2 (RUNX2), and osteocalcin (OCN). DL, alone or in combination with adjunctive therapy to SRP in the treatment of experimental periodontitis, resulted in a decreased local inflammatory response. At 7-days posttreatment, the DL and SRP/DL groups had fewer TRAP-positive cells and more RUNX2-positive cells. There was greater OCN immunolabeling in the DL group than in the C and SRP groups at 15 days. There was less ABL in the DL and SRP/DL groups at 15 and 30 days. In conclusion, DL was effective in the treatment of ligature-induced periodontitis in rats, both when used alone and when used as adjunctive therapy to SRP. PMID:24733282

  5. Effects of subchronic phencyclidine (PCP treatment on social behaviors, and operant discrimination and reversal learning in C57BL/6J mice

    Full Text Available Subchronic treatment with the psychotomimetic phencyclidine (PCP has been proposed as a rodent model of the negative and cognitive/executive symptoms of schizophrenia. There has, however, been a paucity of studies on this model in mice, despite the growing use of the mouse as a subject in genetic and molecular studies of schizophrenia. In the present study, we evaluated the effects of subchronic PCP treatment (5 mg/kg twice daily x 7 days, followed by 7 days withdrawal in C57BL/6J mice on 1 social behaviors using a sociability/social novelty-preference paradigm, and 2 pairwise visual discrimination and reversal learning using a touchscreen-based operant system. Results showed that mice subchronically treated with PCP made more visits to (but did not spend more time with a social stimulus relative to an inanimate one, and made more visits and spent more time investigating a novel social stimulus over a familiar one. Subchronic PCP treatment did not significantly affect behavior in either the discrimination or reversal learning tasks. These data encourage further analysis of the potential utility of mouse subchronic PCP treatment for modeling the social withdrawal component of schizophrenia. They also indicate that the treatment regimen employed was insufficient to impair our measures of discrimination and reversal learning in the C57BL/6J strain. Further work will be needed to identify alternative methods (e.g., repeated cycles of subchronic PCP treatment, use of different mouse strains that produce discrimination and/or reversal impairment, as well as other cognitive/executive measures that are sensitive to chronic PCP treatment in mice.

    Full Text Available Background: We conducted a study to evaluate efficacy and safety of dimeticone 4%, a lotion with no conventional insecticide activity, to cure lice infection and to prevent spread of infestation/reinfestation by prophylaxis of classmates.Methods: The study is carried out between April 2008 and June 2008 in Petranova International Institute in Rome. A total of 131 children, aged 3 to 13 years (median age: 7 years were included in the study. All participants received treatment with dimeticone 4% that was applied both to children with the infestation, to cure it, and to all classmates, to prevent the spreading of the infestation. They have been controlled after 7 and 30 days from the application of dimeticone.Results: At baseline we found a positivity of lice infestation in 23/131 children (17.6%, whereas 108/131 (82.4% children were free from lice. After 7 days of treatment with dimeticone 4%, 7/23 (30.4% positive children still had lice infestation, with a cure rate of 69.6% (16/23. At 30 days 26/131 children (19.9% were infested: 15 children were lice free at baseline whereas 11 had lice at both evaluations; the cure rate amounted to 52.2% (12/23. The reinfestation rate (percentage of positive children that showed negativity at baseline was 5.3% (7/131 at 7 days and 11.5% (15/131 at 30 days.Conclusion: The lower reinfestation rate showed in our trial suggests that this approach could be effective in reducing spreading of head lice in small communities. More studies are needed to confirm our findings

  7. Gonadotropin-releasing hormone treatment induces follicular growth and ovulation in seasonally anestrous mares.

    Johnson, A L

    1987-06-01

    A study was conducted to evaluate the effectiveness of gonadotropin-releasing hormone (GnRH) pulse infusion to stimulate follicular development and induce ovulation in seasonally anestrous standardbred mares. Seventeen mares were selected for use in this experiment, on the basis of a previous normal reproductive history, and were housed under a photoperiod of 8L:16D beginning one week prior to the start of the experiment (second week in January). Mares were infused with 20 micrograms (n = 7) or 2 micrograms (n = 6) GnRH/h, or were subjected to photoperiod treatment only (controls, n = 4). Serum concentrations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and progesterone did not vary, and neither significant follicular development nor ovulation was observed in any control mare throughout the experimental period (greater than 60 days). By contrast, both groups of GnRH-treated mares showed elevated serum concentrations of LH and FSH within one day after the start of infusion. Mares infused with 20 micrograms GnRH/h had at least one follicle greater than or equal to 25 mm in 7.4 +/- 1.3 (mean +/- SEM) days following the start of infusion, and ovulated in 12.0 +/- 0.7 days. In the 2-microgram-GnRH/h treatment group, a 25-mm follicle was detected in 5.7 +/- 0.7 days, and ovulation occurred after 10.0 +/- 0.3 days of infusion. Ovulation in every instance was followed by a functional luteal phase, as indicated by the profiles of progesterone secretion.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3113502

    Background Adolescent cervical kyphosis refers to manifestation characterized by loss of physiological cervical lordosis with involvement of multiple cervical vertebrae.There is no standard treatment strategy for this disease,especially in those patients who need surgical intervention.The aim of this study was to evaluate the surgical staged treatment for moderate to severe adolescents cervical kyphosis.Methods A total of 26 adolescent with cervical kyphosis were retrospectively assigned into following two groups according to the magnitude of kyphosis:moderate group (n=17),the Cobb angle was 46.6°±4.8°.The surgical procedure was that skull traction was first carried out for 5-7 days and then the anterior fusion and instrumentation were performed.Severe group (n=9),the Cobb angle was 61.6°±4.8°.The treatment strategy was that the anterior release were first performed,followed by skull traction for 7-10 days,and then anterior fusion were performed.Radiographic evaluation was performed postoperatively.Results Three days after surgery,the X-ray examination showed that the Cobb angle was -8.9°±6.8° in the moderate group and -6.0°±6.3° in the severe group.The deformed appearance was obviously corrected,with neck pain and neurologic function improved significantly.Further magnetic resonance imaging (MRI) indicated the physiology curvature of the cervical spine had been reconstructed.Conclusion Surgical staged treatment may be an ideal therapeutic intervention for cervical kyphosis patients with a Cobb angle exceeding 35° in adolescents.

  10. Effects of Using Pozzolan and Portland Cement in the Treatment of Dispersive Clay

    Vakili, A. H.; Selamat, M. R.; Moayedi, H.

    2013-01-01

    Use of dispersive clay as construction material requires treatment such as by chemical addition. Treatments to dispersive clay using pozzolan and Portland cement, singly and simultaneously, were carried out in this study. When used alone, the optimum amount of pozzolan required to treat a fully dispersive clay sample was 5%, but the curing time to reduce dispersion potential, from 100% to 30% or less, was 3 month long. On the other hand, also when used alone, a 3% cement content was capable of reducing dispersion potential to almost zero percent in only 7 days; and a 2% cement content was capable of achieving similar result in 14 days. However, treatment by cement alone is costly and could jeopardize the long term performance. Thus, a combined 5% pozzolan and 1.5% cement content was found capable of reducing dispersion potential from 100% to zero percent in 14 days. The results indicate that although simultaneous treatment with pozzolan and cement would extend the required curing time in comparison to treatment by cement alone of a higher content, the task could still be carried out in a reasonable period of curing time while avoiding the drawbacks of using either pozzolan or cement alone.

    Serra, Christian; Pinna, Stefania; Venturini, Antonio; Rossi, Giacomo; Fortuna, Damiano

    2002-10-01

    We have treated with CO2 laser surgery 40 cases which contemplated: stomatitis and other oral pathologies, anorectal, cutaneous, subcutaneous lesions, and other ophthalmic ones. The parameters employed to evaluate surgical treatment success were: histological analyses, time of healing process and incidence (per cent) of relapses. During the T/3 period (45 days) all cases of feline stomatitis relapsed. The 83% of pets that suffered of anorectal pathologies healed up to 21 days and no relapse was observed in T/4 period (180 days). The cutaneous and subcutaneous nodules vaporization caused lesions that healed during 7 days (T/1) and no relapse was observed after laser treatment. In cutaneous chronic ulcers and in reptilian abscesses we had the lesions reparation by second intention healing in T/3. A case of feline oral squamocellular carcinoma relapsed in T/3 after laser treatment. The results showed three different level of utility: indispensable, useful but unnecessary, inefficacious. The CO2 laser application resulted the best treatment for anorectal pathologies, cutaneous ulcerations and reptilian abscesses. The laser surgery was only useful but unnecessary in treatment of cutaneous and subcutaneous neoformations and also in oral and peri-ophthalmic pathologies. Finally, the laser application appeared inefficacious in squamocellular carcinoma and in chronic phlogosis of feline oral cavity.

  13. 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. PMID:24202878

    Although preclinical and clinical studies have established the efficacy of lithium augmentation of antidepressant drugs, the mechanism of action of lithium augmentation is not fully understood. Our previous study reported that subchronic lithium treatment enhanced the anxiolytic-like effect of systemic mirtazapine. In the present study, we examined the effect of subchronic lithium in combination with acute local intracerebral injection of mirtazapine on fear-related behaviors in a contextual fear conditioning test in rats to clarify the target brain region of lithium augmentation of mirtazapine. After conditioning by footshock, diet (food pellets) containing Li2CO3 at a concentration of 0.2% was administered for 7 days. Ten min before testing and 7 days after conditioning, mirtazapine (3μg/site) in a volume of 0.5µl was acutely injected into the median raphe nucleus (MRN), hippocampus or amygdala. The combination of subchronic lithium and acute mirtazapine microinjection into the MRN but not the hippocampus or the amygdala reduced fear expression synergistically. These results suggest that intra-MRN mirtazapine treatment with subchronic lithium exerts the anxiolytic-like effect through the facilitation of the MRN-5HT pathway. PMID:27154172

    2013-01-01

    Full Text Available Objectives: Flow diverter stents (FDS are new neuroendovascular tools able to achieve the complete and curative treatment of aneurysm by reconstruction of the parent arteries from which the aneurysm arises. We present our initial experience with flow diverter embolization devices and follow-up results. Materials and Methods: Patients with large, giant and wide necked aneurysms, saccular, fusiform and recurrent aneurysms were selected for the treatment. All patients were pretreated with dual antiplatelet agents at least for 7 days before procedure and continued taking both agents for 3 months after treatment. A MRI was done after 3 months of treatment and digital subtraction angiogram was performed at 4 months of treatment. After 1 year both MRI and digital subtraction angiogram was performed. Results: 11 patients (age range 37 year to 79 year, mean 51.1 with 11 intracranial aneurysms were treated with 15 flow diverter stents. 9 aneurysm were located on the anterior circulation and 2 on posterior circulation. 8 aneurysms were large (10-25 mm, 2 were small (25 mm with mean largest diameter of 13.22 mm. 9 were saccular aneurysm and 2 were fusiform, out of these 3 were remnant of the previously treated aneurysm. Treatment was achieved with 10 Silk stents in 7 patients and 5 Pipeline embolization devices in 4 patients. The mean time between treatment and follow up was 9.6 months (range 4-12 months. One mortality was noted due to rebleed after 3 weeks of treatment. Complete angiographic occlusion was achieved in 9 (90% patients after 4 months and 1 (10% patient had near complete occlusion at 12 months. All the patients were stable clinically during follow up period. Conclusion: Endovascular treatment with FDS is safe, easy, and permanent treatment for the selected group of aneurysms. The complete occlusion rate in follow-up study approaches 100% with no angiographic recurrence in this study.

    For identifying drugs which might be effective in the treatment of human Babesia microti infections, 20 selected antiprotozoal agents or combinations of agents were tested for activity against B. microti in Mongolian jirds (meriones unguiculatus). 4-Methyl-primaquine and aromatic diamidines, including diminazene and pentamidine, were the most effective compounds tested.

  18. Reduced PBR/TSPO Expression After Minocycline Treatment in a Rat Model of Focal Cerebral Ischemia: A PET Study Using [18F]DPA-714

    Background: Many new candidate pharmaceuticals designed to improve recovery after stroke have been proposed recently, but there are still too few molecular imaging methods capable to assess their efficacy. A hallmark of the inflammatory reaction that follows focal cerebral ischemia is overexpression of the mitochondrial peripheral benzodiazepine receptor/18 kDa translocator protein (PBR/TSPO) in the monocytic lineage and astrocytes. This overexpression can be imaged with positron emission tomography (PET) using PBR/TSPO-selective radioligands such as [18F]DPA-714. Purpose: Here, we tested whether PET with [18F]DPA-714 would evidence the effect of minocycline, a broad spectrum antibiotic presently tested as neuro-protective agent after stroke, on the inflammatory reaction induced in an experimental model of stroke. Procedures: Ten rats were subjected to a 2-h transient middle cerebral artery occlusion with reperfusion. Minocycline or saline was intravenously administrated 1 h after reperfusion and daily during the following 6 days. PET studies were performed using [18F]DPA-714 at 7 days after cerebral ischemia. Results: In vivo PET imaging showed a significant decrease in [18F]DPA-714 uptake at 7 days after cerebral ischemia in rats treated with minocycline with respect to saline-treated animals. Minocycline treatment had no effect on the size of the infarcted area. Conclusion: Minocycline administered daily during 7 days after ischemia decreases [18F]DPA- 714 binding, suggesting that the drug exerts an anti-inflammatory activity. [18F]DPA-714 PET is a useful bio-marker to study novel anti-inflammatory strategies in experimental cerebral ischemia. (authors)

  19. Stem-cells used in treatment of periodontal bone defects

    The aggressive periodontitis might to provoke the tooth loss, of its function and to affect the patient's aesthetics. The techniques used for the lost bone regeneration, not always are successful and in occasions are very expensive. For years it is working in tissues regeneration by stem-cells implantation. Periodontium could be a potential for this task. This is a study of a female patient aged 26 with an apparent health status and aggressive periodontitis backgrounds treated from 10 years ago, seen in our service due to dental mobility producing mastication nuisances. At clinical examination we noted systemic chronic inflammation of gums, grade II and III dental mobility in incisives and molars teeth, 4-8 mm systemic periodontal sacs and furcation lesions in inferior molars. At radiographs advanced bone losses and a decrease of systemic bone density are noted. After written consent and the initial preparation, we carried out a periodontal flap in the 35 and 37 teeth zone, where the stem-cells concentrate was placed, in bone defects of superior molars (16-17) and previous radicular scraping and isolation, treatment consisted in stem-cells perfusion without flap. There were not postoperative side effects. At 7 days there was a normal coloration, at three months on noted at radiograph a bone neoformation, and at six months gum remained healthy, with a decrease of dental mobility in segment treated and in the evolutionary radiograph it was evidenced the formation and increase of density

    Full Text Available OBJECTIVES: To evaluate the clinical effects of blood purification for treating fulminant hepatic failure (FHF. METHODS: Thirty-three severe FHF patients with hepatic encephalopathy (HE above grade III were subjected to a combined blood purification treatment in addition to the comprehensive liver protection therapy. Patients underwent continuous hemofiltration on a daily basis during the daytime followed by sequential treatment with plasma exchange or hemodialysis every 2-3 days. The therapeutic effects of this treatment were evaluated. RESULTS: After treatment with blood purification, restoration of consciousness (those who abandoned the treatment without restoration of consciousness were excluded was achieved in 6 of 8 cases (75% in acute liver failure (ALF group, 3 of 3 cases (100% in subacute liver failure (SALF group, and 9 of 14 cases (64.29% in acute/subacute on chronic liver failure (A/SCLF group. Of all cases, 11 patients restored consciousness after 7 days in a coma. The rate of long-term survival (those who abandoned the treatment were excluded was 3/7 (42.86% for ALF group, 2/2 (100% for SALF group, and 1/11 (9.09% for A/SCLF group. The levels of hemoglobin and platelet in peripheral blood were significantly reduced after blood purification. CONCLUSIONS: Treatment of FHF patients with daily continuous hemofiltration during the daytime is effective in treating HE and in improving health status in the early stages of the disease. Long-term prognosis also benefits from this treatment. The rate of consciousness recovery and long-term survival is highest in SALF group followed by ALF group. This treatment is less effective in A/SCLF patients. It should be noted that blood purification procedure may cause damage to blood cells.

    Abdelrahim, Ramy A.; Badr, Nadia A.; Baroudi, Kusai

    2016-01-01

    Objective: This study was aimed to assess the effect of anodized and alkali-heat surface treatment on the bioactivity of titanium alloy (Ti-6Al-4V) after immersion in Hank's solution for 7 days. Materials and Methods: Fifteen titanium alloy samples were used in this study. The samples were divided into three groups (five for each), five samples were anodized in 1M H3PO4 at constant voltage value of 20 v and another five samples were alkali-treated in 5 M NaOH solution for 25 min at temperature 60°C followed by heat treatment at 600°C for 1 h. All samples were then immersed in Hank's solution for 7 days to assess the effect of surface modifications on the bioactivity of titanium alloy. The different treated surfaces and control one were characterized by X-ray diffraction, atomic force microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Fourier transformation infra-red spectroscopy. Statistical analysis was performed with PASW Statistics 18.0® (Predictive Analytics Software). Results: Anodization of Ti-alloy samples (Group B) led to the formation of bioactive titanium oxide anatase phase and PO43− group on the surface. The alkali-heat treatment of titanium alloy samples (Group C) leads to the formation of bioactive titania hydrogel and supplied sodium ions. The reaction between the Ti sample and NaOH alkaline solution resulted in the formation of a layer of amorphous sodium titania on the Ti surface, and this layer can induce apatite deposition. Conclusions: The surface roughness and surface chemistry had an excellent ability to induce bioactivity of titanium alloy. The anodization in H3PO4 produced anatase titanium oxide on the surface with phosphate originated from electrolytes changed the surface topography and allowed formation of calcium-phosphate.

  2. Treatment of enterocutaneous fistulas with TPN and somatostatin, compared with patients who received TPN only.

    Spiliotis, J; Vagenas, K; Panagopoulos, K; Kalfarentzos, F

    1990-12-01

    Eighteen patients with post-operative enterocutaneous fistulas were treated with total parenteral nutrition (TPN), skin care, infection control and intravenous somatostatin (SMS) 250 micrograms/h. This group was compared with 30 patients treated with standard medical treatment (total parenteral nutrition (TPN), skin care and infection control). In the SMS group the fistula output was reduced to 50% in three days and spontaneous closure was observed in 14 patients after a mean of 6.1 +/- 3.1 days of treatment with SMS, and in 18.2 +/- 6.3 days after the TPN administration. In the control group the fistula output was reduced by up to 50% after a week and spontaneous closure occurred in 20 patients in a mean of 27.4 +/- 8.7 days after the start of treatment. These results are statistically significant. There was one (5.5%) death in the SMS group compared with three (10%) deaths in the other, and glucose intolerance was observed in two (11%) patients in the SMS group. Somatostatin has been shown to be useful in the conservative treatment of enterocutaneous fistulas because of its ability to reduce output and accelerate closure. PMID:1983231

    2015-02-01

    Discrepancy between subjective and objective measures of sleep is associated with insomnia and increasing age. Cognitive behavioural therapy for insomnia improves sleep quality and decreases subjective-objective sleep discrepancy. This study describes differences between older adults with insomnia and controls in sleep discrepancy, and tests the hypothesis that reduced sleep discrepancy following cognitive behavioural therapy for insomnia correlates with the magnitude of symptom improvement reported by older adults with insomnia. Participants were 63 adults >60 years of age with insomnia, and 51 controls. At baseline, participants completed sleep diaries for 7 days while wearing wrist actigraphs. After receiving cognitive behavioural therapy for insomnia, insomnia patients repeated this sleep assessment. Sleep discrepancy variables were calculated by subtracting actigraphic sleep onset latency and wake after sleep onset from respective self-reported estimates, pre- and post-treatment. Mean level and night-to-night variability in sleep discrepancy were investigated. Baseline sleep discrepancies were compared between groups. Pre-post-treatment changes in Insomnia Severity Index score and sleep discrepancy variables were investigated within older adults with insomnia. Sleep discrepancy was significantly greater and more variable across nights in older adults with insomnia than controls, P ≤ 0.001 for all. Treatment with cognitive behavioural therapy for insomnia was associated with significant reduction in the Insomnia Severity Index score that correlated with changes in mean level and night-to-night variability in wake after sleep onset discrepancy, P sleep discrepancy patterns may guide more targeted treatments for late-life insomnia.

    2014-09-01

    26 patients were included into HIFU and 74 group in group of the combined treatment (TURP+HIFU. Selection criteria for HIFU ablation were the localized cancer of a prostate concerning which earlier it wasn't carried out treatments, and level of a PSA at the time of statement of the diagnosis 15 ng/ml. All patients corresponding to these by criteria, were considered as candidates for treatment and inclusion in the analysis. The nadir and stability of PSA, the histologic conclusion, IPSS, quality of life and complication were estimated at time of postoperative supervision. Results: Statistically significant influence of a combination TURP+HIFU for the term of transurethral drainage of a bladder (a median of 40 days against 7 days, incontience frequency (15.4% against 6.9%, infections of urinary ways (47.9% against 11.4% and IPSS change during the postoperative period (on the average 8.91 against 3.37 is noted. During the short period of supervision it wasn't observed considerable changes in relation to efficiency: in HIFU group the frequency of repeated sessions made 25%, in TUR/HIFU group 4%. Conclusion: HIFU therapy is modern, minimum invasive method of a cancer therapy of a prostate. The combination of a transurethral resection and HIFU ablation significantly reduces the frequency of the complications connected with treatment. Maintaining the patient after combined TURP and HIFU ablation is comparable with maintaining the patient after usual TURP.

Materials and Methods: This randomized clinical trial was conducted on 120 women with vulvo vaginal candidiasis during a six month period. All patients answered a standard questionnaire containing questions about symptoms of vulvovaginal candidiasis and presence of vaginal discharge and signs of vulvar and vaginal inflammation were documented according to physical examination. Two swabs of vaginal discharge were obtained for each woman, one for direct smear, another for culture. The culture medium was Sabouraud Dextrose Agar (SDA. Patients were randomized into two groups of clotrimazole (vaginal cream for 7 days and 150 mg fluconazole in a single dose. Clinical and paraclinical responses were calculated.Results: Clinical improvement occurred in 96 cases (80%. This value was 86.7% and 73.3%for clotrimazole and fluconazole, respectively (P-value=0.04. Paraclinical response on tenth day of treatment was observed in 87 patients (72.5%. This value was 66.7% and 78.3%for clotrimazole and fluconazole groups, respectively (P-value=0.110. Mean days of treatment was 4.06 ±1.30 days for clotrimazole and 2.70 ±0.78 days for fluconazole (p value =0.031.Conclusion: Most of the clinical and paraclinical responses to the drugs used for the treatment of vulvo vaginal candidiasis are in the favour of fluconazole.

    Full Text Available BACKGROUND: E. coli belonging to the phylogenetic group B2 are linked to Inflammatory Bowel Disease (IBD. Studies have shown that antimicrobials have some effect in the treatment of IBD, and it has been demonstrated that E. coli Nissle has prophylactic abilities comparable to 5-aminosalicylic acid (5-ASA therapy in ulcerative colitis. The objective of this study was to test if ciprofloxacin and/or E. coli Nissle could eradicate IBD associated E. coli in the streptomycin-treated mouse intestine. RESULTS: After successful colonization with the IBD associated E. coli strains in mice the introduction of E. coli Nissle did not result in eradication of either IBD associated strains or an E. coli from a healthy control, instead, co-colonization at high levels were obtained. Treatment of mice, precolonized with IBD associated E. coli, with ciprofloxacin for three days alone apparently resulted in effective eradication of tested E. coli. However, treatment of precolonized mice with a combination of ciprofloxacin for 3 days followed by E. coli Nissle surprisingly allowed one IBD associated E. coli to re-colonize the mouse intestine, but at a level 3 logs under E. coli Nissle. A prolonged treatment with ciprofloxacin for 7 days did not change this outcome. CONCLUSIONS: In the mouse model E. coli Nissle can not be used alone to eradicate IBD associated E. coli; rather, 3 days of ciprofloxacin are apparently efficient in eradicating these strains, but surprisingly, after ciprofloxacin treatment (3 or 7 days, the introduction of E. coli Nissle may support re-colonization with IBD associated E. coli.
