BackgroundThere are many drugs recommended for pain relief in patients with migraine headache.MethodsIn a prospective double blind randomized clinical trial, 90 patients (age ≥ 18) presenting to Emergency medicine Department with Migraine headache were enrolled in two equal groups. We used intravenous propofol (10 mg every 5–10 minutes to a maximum of 80 mg, slowly) and intravenous dexamethasone (0.15 mg/kg to a maximum of 16 mg, slowly), in group I and II, respectively. Pain explained by patients, based on VAS (Visual Analogue Scale) was recorded at the time of entrance to ED, and after injection. Data were analyzed by paired samples t test, using SPSS 16. P < 0.05 was considered to be statistically significant.ResultsThe mean of reported pain (VAS) was 8 ± 1.52 in propofol group and 8.11 ± 1.31 in dexamethasone group at presenting time (P > 0.05). The VAS in propofol group was obviously decreased to 3.08 ± 1.7, 1.87 ± 1.28 and 1.44 ± 1.63 after 10, 20 and 30 minutes of drug injection, respectively. The VAS in dexamethasone group was 5.13 ± 1.47, 3.73 ± 1.81 and 3.06 ± 2 after 10, 20 and 30 minutes of drug injection, respectively. The mean of reported VAS in propofol group was less than dexamethasone group at the above mentioned times (P < 0.05). The reduction of headache in propofol group, also, was very faster than dexamethasone group (P < 0.05). There were no adverse side effects due to administration of both drugs.ConclusionsIntravenous propofol is an efficacious and safe treatment for patients presenting with Migraine headache to the emergency department.Trial registrationClinical Trials IRCT201008122496N4
BackgroundSeveral studies have been conducted on managing migraine headaches and developing effective medications for decreasing migraine-associated pain.Case presentationIntravenous propofol was prescribed (10 mg every 5 min) for eight patients with intractable migraine headaches visiting the Emergency Department. The average pain score experienced by patients was recorded using the Visual Analogue Scale at the beginning of the treatment procedure and following the injection for 30 min (5-min intervals). The patients’ reported pain scores decreased significantly (P = 0.01) from 8.87 ± 0.83 (CI: 8.17, 9.57) to 1.12 ± 0.83 (CI: 0.43, 1.82) before and 30 min following the injection.DiscussionIt seems that in the treatment of intractable migraine headaches, GABAergic receptors, compared to the normal conditions, have a lower activity status.ConclusionBecause of the high tendency of propofol to GABAergic receptors, it probably changes this physiological condition by activating the receptors, which results in a significant pain reduction.
Alzheimer is a progressive neurological disease that results in irreversible loss of neurons and includes about two thirds of all cases of dementia. Toxoplasma gondii may be an important infectious agent involved in neurodegenerative diseases. The aim of this study was to investigate the correlation between Toxoplasma as an etiologic agent in the progress of Alzheimer's disease. This case control study was conducted on 75 Alzheimer's patients and 75 healthy volunteers. Blood samples were obtained and anti-Toxoplasma IgG and IgM tests were done by using ELISA technique. DNA was extracted from buffy coat and then GRA6 gene and SAG2 loci were amplified by PCR and nested PCR, respectively. Chi-square, Fisher's test, and binary logistic regression were used for data analysis. A percentage of 61.3 % of Alzheimer's patients and 62.6 % of healthy volunteers were positive for anti-Toxoplasma IgG but all participants were negative for anti-Toxoplasma IgM. There were no significant differences between Alzheimer's patients with their controls in terms of anti-Toxoplasma IgG antibody (P = 0.5). Due to lack of positive IgM sample, results of the molecular methods were negative by GRA6 and SAG2 fragments amplification. This result shows that, infection with T. gondii cannot be considered as a risk factor for etiology and developing Alzheimer's disease.
Background. Intravenous tissue plasminogen activator, a time dependent therapy, can reduce the morbidity and mortality of acute ischemic stroke. This study was designed to assess the effect of simple in-hospital interventions on reducing door-to-CT (DTC) time and reaching door-to-needle (DTN) time of less than 60 minutes. Methods. Before any intervention, DTC time was recorded for 213 patients over a one-year period at our center. Five simple quality-improvement interventions were implemented, namely, call notification, prioritizing patients for CT scan, prioritizing patients for lab analysis, specifying a bed for acute stroke patients, and staff education. After intervention, over a course of 44 months, DTC time was recorded for 276 patients with the stroke code. Furthermore DTN time was recorded for 106 patients who were treated with IV thrombolytic therapy. Results. The median DTC time significantly decreased in the postintervention period comparing to the preintervention period [median (IQR); 20 (12–30) versus 75 (52.5–105), P < 0.001]. At the postintervention period, the median (IQR) DTN time was 55 (40–73) minutes and proportion of patients with DTN time less than 60 minutes was 62.4% (P < 0.001). Conclusion. Our interventions significantly reduced DTC time and resulted in an acceptable DTN time. These interventions are feasible in most hospitals and should be considered.
Toxoplasma gondii is an obligate intracellular parasite that infects all nucleate cells of vertebrates. Human infected by vertical transmission and also using raw or undercooked meat or food and water that contaminated with mature oocysts. Parkinson's disease as neurodegenerative disease affects people above 60 years. Due to high prevalence of toxoplasmosis in Iran and evidence about effects of T. gondii on neurodegenerative diseases, this study has been conducted to investigate possible correlation between Toxoplasma and Parkinson's disease in Iran. Seventy five Parkinson's patients and equal healthy volunteers were enrolled. After obtaining informed consent and sociodemographic features, 5 ml blood sample were collected and then anti-Toxoplasma IgG and IgM levels were examined by ELISA method. Data was analyzed with Chi-squre and Fisher's test by usig stata 11 software. Binary logistic regression was used for multivariate analysis in assessing the correlation between toxoplasmosis and Parkinson. Eighty five percent of Parkinson's group and 90.3 % of control group were positive for anti-Toxoplasma IgG antibody. In this investigation no statically differences were observed between groups and age, gender, residency and using raw or undercooked meat. There is no significant association between IgG positive titer and Parkinson's disease. However, statistically significant association was found between Parkinson and keeping cat (P = 0.03) as well as the using of undercooked egg (P = 0.004). Although there is high level of anti-Toxoplasma IgG antibody in Parkinson's patients which reflects chronic Toxoplasma infection; we couldn't detect any statistical association between T. gondii infection and Parkinson's disease.
Background:Intravenous thrombolysis is an approved treatment method for patients with acute ischemic stroke (AIS) and is recommended by multiple guidelines. However, it seems that it is less frequently used in the developing countries compared to the developed countries.Objectives:The purpose of this study was to estimate the percentage of patients with AIS, eligible for intravenous thrombolytic therapy, at the main referral center in Northwest Iran and to determine the main barriers for implementation of this method.Patients and Methods:Over one year, 647 patients who were admitted to the emergency department and met the Cincinnati Stroke Scale were enrolled into the study. The center to which patients were admitted, is a tertiary university hospital that has the required infrastructure for thrombolytic therapy in AIS. Factors recorded were neurological examinations and time between onset of symptoms and hospital arrival, hospital arrival and performance of brain computed tomography (CT) scanning, and hospital arrival to complete the investigations. Patients eligible for intravenous thrombolytic therapy were identified according to the American Heart Association (AHA) guidelines.Results:Mean time interval between hospital arrival and completion of brain CT scanning was 91 minutes (range: 20–378 minutes) and mean time from hospital arrival to completion of investigations was 150 minutes (range: 30–540 minutes). A total of 159 (31.3%) patients arrived at hospital within 3 hours of the onset of symptoms (early enough for intravenous thrombolytic therapy). However, 81.7% (130/159) of these patients missed thrombolytic therapy due to delayed performance of brain CT scanning and laboratory tests and 38.3% (61/159) had contraindications. The remaining 16 patients (10% of those who arrived within 3 hours and 3.1% of all cases) were eligible for thrombolytic therapy.Conclusions:The major barriers for thrombolytic therapy for patients with AIS in this setting were delays in the provision of in-hospital services, like initial patient assessment, CT scans or laboratory studies. These results were in contrast with previous reports.
Objective. This study was set to assess the effect of renal dysfunction on outcome of stroke patients treated with intravenous thrombolysis (IVT). Methods. This multicenter research involved 403 patients from January 2009 to March 2015. Patients were divided into two groups: (1) control group with GFR ≥ 45 mL/min/1.73 m2 and (2) low GFR group with GFR < 45 mL/min/1.73 m2. Outcome measurements were poor outcome (mRS 3–6) and mortality at 3 months and symptomatic intracerebral hemorrhage (SICH) within the first 24–36 hours. Univariate and multivariate regression analyses were performed, and odds ratios (ORs) were determined at 95% confidence intervals (CIs). Results. Univariate analyses determined that every decrease of GFR by 10 mL/min/1.73 m2 significantly increased the risk of poor outcome (OR 1.19, 95% CI 1.09–1.30, p < 0.001) and mortality (OR 1.18, 95% CI 1.06–1.32, p = 0.002). In multivariate regression, adjusted for all variables with p value < 0.1, low GFR (GFR < 45 versus GFR equal to or more than 45) was associated with poor outcome (OR adjusted 2.15, 95% CI 1.01–4.56, p = 0.045). Conclusion. In IVT for acute stroke, renal dysfunction with GFR < 45 mL/min/1.73 m2 before treatment determined increased odds for poor outcome compared to GFR of more than 45 mL/min/1.73 m2.
Inflammation is thought to play a significant role in the underlying pathophysiology of migraine headaches which could be controlled by corticosteroids. The present study was conducted to determine and compare the pain relieving effect of dexamethasone versus morphine on patients with acute migraine headache. During this double blinded clinical trial study, 190 patients who met the International Headache Society definition of acute migraine headache were evaluated at emergency department of Tabriz Imam Reza Hospital. After giving informed consent, patients were randomly enrolled into two groups: Receiving either 8 mg dexamethasone (group A) or 0.1 mg kg(-1) morphine (group B) intravenously. Severity of the headache was determined using Visual Analog Scale (VAS) scoring method at baseline (VAS-A), 10 min (VAS-B), 60 min (VAS-C) and 24 h (VAS-D) after intervention. The mean age of patients was 44.17 +/- 16.20 years, 61.57% male and 38.43% female. The mean of VAS-A and VAS-B scores was not statistically different between two groups (p = 0.236 and p = 0.481), but the mean of VAS-C and VAS-D scores in the group A were significantly lower than the group B (p = 0.017, p = 0.010). In long-term (1 h and 24 h after administration), dexamethasone reduces the severity of acute migrant headache more than morphine.
