- چکیده انگلیسی: Background: According to statistics, at least four percent of people experience one or more nonfebrile seizures in their life span. Continuous Electroencephalography (cEEG) Monitoring is a useful diagnostic tool for seizure detection. The purpose of this study was to investigate EEG findings in first-time seizure patients referred to emergency department (ED).
Methods: The present cross-sectional study was conducted on 80 first-time seizure patients admitted to ED, who were selected by convenience sampling method. The inclusion criteria were all patients aged more than 17 years with first-time seizure and informed written consent to participate in the study, and the exclusion criteria were cases where the seizure was not confirmed by a neurologist. An EEG was taken in the ED from the patient within 24 hours of the first attack. Finally, the frequency of pathological changes in EEG findings was determined in these patients. The statistical data were analyzed by SPSS software using descriptive statistics (measures of central tendency and dispersion and frequency distribution) and inferential statistics.
Results: The patients consisted of 35 (43.8%) males and 45 (56.2%) females. The patients had a mean age of 52.54±19.33 years and a median of 53 years. Among the patients, 46 (57.5%) had normal EEG findings, and 34 (42.5%) had abnormal (pathological) EEG findings.
Conclusion: According to the results of this study, 42.5% of patients had abnormal EEG findings, but it seems that accurate examination would require the use of other diagnostic tools along with EEG to diagnose patients with epilepsy and seizure more precisely.- انتشار مقاله: 17-04-1398

- چکیده:
- چکیده انگلیسی: The management of injured patients is a critical issue in pre-hospital and emergency departments. Trauma victims are usually young and the injuries may lead to mortality or severe morbidities. The severity of injury can be estimated by observing the anatomic and physiologic evidences. Scoring systems are used to present a scale of describing the severity of the injuries in the victims.
We reviewed the evidences of famous scoring systems, the history of their development, applications and their evolutions. We searched electronic database PubMed and Google scholar with keywords: (trauma OR injury) AND (severity OR intensity) AND (score OR scale).
In this paper, we are going to present a definition of scoring systems and discuss the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS), the most acceptable systems, their applications and their advantages and limitations.
Several injury-scoring methods have been introduced. Each method has specific features, advantages and disadvantages. The AIS is an anatomical-based scoring system, which provides a standard numerical scale of ranking and comparing injuries. The ISS was established as a platform for trauma data registry. ISS is also an anatomically-based ordinal scale, with a range of 1-75. Several databases and studies are formed based on ISS and are available for trauma management research.
Although the ISS is not perfect, it is established as the basic platform of health services and public health researches. The ISS registering system can provide many opportunities for the development of efficient data recording and statistical analyzing models.- انتشار مقاله: 12-02-1393

- چکیده:
- چکیده انگلیسی: Low-phosphorus (P) stress as a key factor limiting plant growth and production is common in most agricultural soils. Most of the soil-applied phosphate will be rapidly immobilized and most of annually applied phosphate fertilizers are fixed in the soil in organic forms by adsorption, sedimentation and transformation. However, excess P application may lead to contamination of water sources by enriching of water bodies with nutrients that cause eutrophication. Thus understanding the mechanisms that are used by plants to cope with low-P stress will be supportive to develop more competent breeding and genetic engineering schemes for generating improved phosphorus efficient crops. To cope with P deficiency and maintenance of phosphate homeostasis, plants have developed different adaptive mechanisms, including alterations in root morphology, recycling of inorganic phosphate (Pi) and induction of acid phosphatases (APases). To establish these strategies, numerous genes are involved in alternative metabolism pathways that are regulated by complex Pi signaling networks. In this review, we intend to summarize current advances in research on the mechanisms of P efficient crops and its breeding strategies, with a particular emphasis on APase and root architecture roles in response to low-P stress.

- چکیده انگلیسی: Direct regenerations by using mature cotyledonary node as a explants has been shown to be time-saving and convenient strategy for micropropagation of soybean. So we have evaluated regeneration protocol through single shoot using cotyledonary node as a rapid and efficient protocol for two soybean cultivars and one mutant line. Cotyledonary nodes explants obtained from 7-days-old in vitro seedlings. After 28 days, the percent of regeneration and after 42 days, regeneration area were calculated. The results showed that percent of regeneration and regeneration area of mutant line was significantly more than two cultivars, L17 and Williams. After shoot induction, plants were transferred to shoot elongation medium followed by transferring plants to rooting medium. The results showed that the percent of rooting was not significantly affected by genotypes. In another experiment to test kanamycin sensitivity of regenerated shoots, it was found that kanamaycin with 150 mg/L concentration is lethal for regeneration of soybean shoots from cotyledonary node explants. The results showed that regeneration efficiency of mutant line was significantly more than two other cultivars. Kanamaycin sensitivity of regenerated shoots showed that kanamycin at 150 mg/L or above can be used as a selective agent for all three tested cultivars transformation.

- چکیده:
- چکیده انگلیسی: Introduction: Triage in the interactive atmosphere of the emergency department (ED) has been described as complex and challenging. The influence of nurses’ belief systems on triage decision making has not to the authors’ knowledge been addressed. This study attempted to gain an understanding of the ED nurses’ culture of practice with respect to contextual factors that affect triage decision making.
Methods: A focused micro-ethnographic study based on Spradley’s developmental research sequence (DRS) has been conducted in the emergency department of the Mashhad University hospital, Iran, from February 2014 to February 2015. Data were collected during 300 hours of participant observations that were accompanied by formal and informal interviews, then analyzed based on Spradley’s DRS.
Results: Nine study participants were formally interviewed. From these interviews, eight core beliefs emerged related to nurses’ culture of practice: namely, triage decision making is arbitrary; the facility/locale of the emergency medicine department is the pivotal contextual factor affecting decision making; not every nurse can be assigned to triage; each patient assumes the existence of an emergency condition; the on-duty physician must be known; triage decision making must be considered plausible by colleagues; “they” tell us something, we should do something else; and triage guidelines are not practical.
Conclusion: Contextual factors have a strong tendency to guide triage decision making and violate the principle of patient acuity (that is, that patients with the most acute medical conditions should be prioritized). In response, triage guidelines need to integrate the priorities of patients, nurses, physicians, and administrators.- انتشار مقاله: 12-03-1398

- چکیده:
- چکیده انگلیسی: Introduction: Patient satisfaction is an accurate assessment factor for evaluating the performance of health policies in the community. The purpose of this study is to assess patients' satisfaction with emergency department of Imam Reza hospital of Mashhad Iran.
Materials and Methods: In this cross-sectional study, during six months period from April to October 2012, 420 patients were entered to study in morning, evening and night shifts before being discharged or transferred from emergency department. The Press Ganey questionnaire of patient satisfaction was completed.
Results: 420[daneshgar1] patients in three work shifts of morning (140 patients) evening (140 patients) and night (140 patients) participated in our research. 226 (53.8%) of participants were male and 194(46.2%) were female. The average of patients’ time waiting for doctors' visit was 10.7±6.1 minutes. The mean score of satisfaction during attendance in Emergency Department (ED), during physicians' visit and overall satisfaction was 25.24±5.04, 25.32±5.42, 8.52±1.91 respectively. The highest level of satisfaction is related to speed of admission (81%), medical treatment (76%), nursing skills for doing medical orders (71.4%) and lowest level of satisfaction is related to comfort and pleasantness of the waiting area (45.9%), time the physician spent with the patient (56.5%) and length of wait before going to an exam room (62.8%).
Conclusion: Attempt for reducing waiting time, providing comfort environment, increasing the time of visit with emergency physicians and enhance service quality based on patient needs can reduce the patient dissatisfaction.- انتشار مقاله: 28-06-1393

- چکیده:
- چکیده انگلیسی: Background:Headache is a common clinical symptom which goes far back in human history. This study is a quick review on headache concerning its diagnosis and treatment based on writings of Rhazes and Avicenna as the most distinguished and prominent scholars in Iranian medical history. Methods: In this review the reliable literature on related traditional medicine was investigated. The sources include: Al-Hawi Fi Al-Tibb (Liber the Continens), Mansuri fi al-tahb, the treasure of Khwarazm shah, The Canon of Medicine, Kamil al-Sanate al-Tebie as well as related articles retrieved from different databases. These databases included Scopus, Medline, PubMed, science Direct, SID, and Google Scholar. In addition, other original texts and sources of Neurology were perused and relevant information was abstracted. In this regard, the diseases of the head, Suda (headache), and the subset of the disease, the term of Shaqeeqa (migraine), were searched in original books of Persian medicine. Results: Diagnosis of temperament, diet modification, use of medicinal herbs and treatments such as massage, bloodletting, dry cupping and purgation of the body from various additional materials were considered as important components of the treatment protocol. Conclusion: The differential diagnosis of migraine from other types of headaches, as well as providing a unique and specific theory for the cause of migraine in the works of Rhazes and Avicenna is surprising. Also, the use of multiple therapies in the treatment of migraine and the selection of herbs with sedative, anti-inflammatory and dermal compositions make it necessary to reconsider and study the experiences of traditional medicine practitioners again.

- چکیده انگلیسی: Objective: The purpose of the current study was to assess the success rate of posterior tibial nerve block in the ankle with and without ultrasound guidance for pain management in emergency departments. Methods: This clinical trial was conducted on 80 individuals who needed posterior tibial nerve block in the ankle at the emergency department of Hashemi Nejad hospital and Edalatian emergency center in Mashhad, Iran. The eligible individuals were randomly assigned to one of two groups, designated the control (landmark-based nerve block) and the case group (ultrasound-guided nerve block). The two groups were compared in terms of the main measurable outcomes. The data were analyzed using SPSS software (version 20) by nonparametric tests. Results: According to the findings, the mean and median of nerve block success in the landmark-based and ultrasound-guided methods were significantly different between the two groups, both 15 (P=0.02) and 30 (P=0.001) min post-intervention. In this regard, nerve block with ultrasound guidance had a higher success rate compared to the landmark method. However, no significant difference between the two interventions was found in terms of the mean and median of the procedure duration (P=0.8) and injection frequency (P=0.4). On the other hand, the two groups were significantly different regarding the median and mean of patient satisfaction (P=0.00), duration of analgesia (P=0.004), and nerve block-related complications (P=0.03). Conclusion: The findings revealed that the relatively new technique of nerve block by ultrasound-guide resulted in better outcomes than the landmark-based method. Consequently, this method could be adopted to control acute pain in the emergency departments and improve patient care.
