Any operation leads to body stress and tissue injury that causes pain and its complications. Glucocorticoids such as Dexamethasone are strong anti‑inflammatory agents, which can be used for a short time post‑operative pain control in various surgeries. Main purpose of this study is to evaluate the effect of administration of intravenous (IV) Dexamethasone on reducing the pain after cesarean.
MethodsA double‑blind prospective randomized clinical trial was performed on 60 patients candidate for elective caesarean section. Patients were randomly assigned into two groups: A (treatment: 8 mg IV Dexamethasone) and B (control: 2 mL normal saline). In both groups, variables such as mean arterial blood pressure (MAP), heart rate (HR), respiratory rate (RR), pain and vomiting severity (based on visual analog scale) were recorded in different time points during first 24 h after operation. Statistical methods using repeated measure analysis of variances and t‑test, Mann‑Whitney and Chi‑square tests were used for analyzing data.
FindingsThe results indicated that within‑group comparisons including severity of pain, MAP, RR and HR have significant differences (P < 0.001 for all variables) during the study period. Between group comparisons indicated significant differences in terms of pain severity (P < 0.001), MAP (P = 0.048) and HR (P = 0.078; marginally significant), which in case group were lower than the control group.
ConclusionIV Dexamethasone could efficiently reduce post‑operative pain severity and the need for analgesic consumption and improve vital signs after cesarean section.

Phenytoin is an antiepileptic drug used widely for prophylaxis and treatment of seizure after neurotrauma. Phenytoin has a complex pharmacokinetics and monitoring of its serum concentrations is recommended during treatment. Total phenytoin concentration is routinely measured for monitoring of therapy. In this study, we evaluated the correlation between phenytoin total and free concentrations in neurotrauma critically-ill patients to determine whether the phenytoin total concentration is a reliable predictor of free drug, which is responsible for the therapeutic effects.
MethodsA total of 40 adult head trauma patients evaluated for free (unbound) and total serum phenytoin concentrations. Patients were divided into two groups. GroupA consists of 20 unconscious patients with severe head injury under mechanical ventilation and Group B consists of 20 conscious self-ventilated patients. Correlation and agreement between total and free phenytoin plasma concentrations were analyzed.
FindingsPearson correlation analysis and Bland-Altman test showed weak to moderate correlation (r = 0.528) and poor agreement between free and total phenytoin concentrations in patients with severe trauma and higher Acute Physiology And Chronic Health Evaluation II (APACHE II) scores (GroupA) and good correlation (r = 0.817) and moderate agreement in patients with mild to moderate trauma and lower APACHE II scores (Group B).
ConclusionOur results indicated that total phenytoin serum concentration is not a reliable therapeutic goal for drug monitoring in severely-ill head trauma patients even in the absence of hypoalbuminemia, renal and hepatic failure. It seems justifiable to measure free phenytoin concentration in all severely ill neurotrauma patients.

Tricyclic antidepressant (TCA) poisoning is among highly prevalent and potentially dangerous toxicities. ST‑T changes are observed in the electrocardiogram (ECG) of most of TCA poisoned patients. We aimed to study ST‑T segment changes in TCA toxicity and its probable relationship with other ECG findings.
MethodsThis retrospective study was carried out in Noor and Ali Asghar University Hospital, Isfahan (Iran) in 2012. Patients with TCA toxicity based on the patients’ history who had not consumed any cardio-active drugs and did not have a past medical history of cardiovascular disease in the recent 5 years, were randomly selected and investigated. Their demographic and medical data on admission including ECG, age, sex, type and amount of ingested TCA, poisoning severity score, QRS changes, QT interval, heart axis position and R‑wave were all recorded. ST‑T changes and their relation with other ECG parameters have been determined using statistical analysis.
FindingsMedical records of 272 patients were analyzed. In symptomatic patients, ST change prevalence was 40.8% and T change prevalence was 9.5%. In asymptomatic patients, the frequency of ST and T changes were 4.8% and 0.8%, respectively (P < 0.05). The most common ST and T changes in baseline (on admission) ECG were non‑significant elevation (15.4%), significant elevation (11%) in pre‑cordial leads, and T‑wave flattening (6.6%). A statistically significant correlation was documented between ST segment changes with QRS and R‑wave in aVR. The correlation between T‑wave changes and R‑wave in aVR lead was also significant.
ConclusionST‑T changes in TCA poisoned patients are more prevalent in symptomatic patients. Obviously for a more definite conclusion, it is necessary to design a prospective study with the control group. This may facilitate a better understanding of ST‑T segment changes.

The objective of this study is to analyze the health‑care cost by calculating the direct and indirect costs of diabetes with co‑morbidities in south India.
MethodsA prospective observational study was conducted at Rohini super specialty hospital (India). Patient data as well as cost details were collected from the patients for a period of 6 months. The study was approved by the hospital committee prior to the study. The diabetic patients of age >18 years, either gender were included in the study. The collected data was analyzed for the average cost incurred in treating the diabetic patients and was calculated based on the total amount spent by the patients to that of total number of patients.
FindingsA total of 150 patients were enrolled during the study period. The average costs per diabetic patient with and without co‑morbidities were found to be United States dollar (USD) 314.15 and USD 29.91, respectively. The average cost for those with diabetic complications was USD 125.01 for macrovascular complications, USD 90.43 for microvascular complications and USD 142.01 for other infections. Out of USD 314.15, the average total direct medical cost was USD 290.04, the average direct non‑medical cost was USD 3.75 and the average total indirect cost was USD 20.34.
ConclusionOur study results revealed that more economic burden was found in male patients (USD 332.06), age group of 51‑60 years (USD 353.55) and the patients bearing macrovascular complications (USD 142.01). This information can be a model for future studies of economic evaluations and outcomes research.

Emergency departments (EDs) are characterized by simultaneous care of multiple patients with various medical conditions. Due to a large number of patients with complex diseases, speed and complexity of medication use, working in under‑staffing and crowded environment, medication errors are commonly perpetrated by emergency care providers. This study was designed to evaluate the incidence of medication errors among patients attending to an ED in a teaching hospital in Iran.
MethodsIn this cross‑sectional study, a total of 500 patients attending to ED were randomly assessed for incidence and types of medication errors. Some factors related to medication errors such as working shift, weekdays and schedule of the educational program of trainee were also evaluated.
FindingsNearly, 22% of patients experienced at least one medication error. The rate of medication errors were 0.41 errors per patient and 0.16 errors per ordered medication. The frequency of medication errors was higher in men, middle age patients, first weekdays, night‑time work schedules and the first semester of educational year of new junior emergency medicine residents. More than 60% of errors were prescription errors by physicians and the remaining were transcription or administration errors by nurses. More than 35% of the prescribing errors happened during the selection of drug dose and frequency. The most common medication errors by nurses during the administration were omission error (16.2%) followed by unauthorized drug (6.4%). Most of the medication errors happened for anticoagulants and thrombolytics (41.2%) followed by antimicrobial agents (37.7%) and insulin (7.4%).
ConclusionIn this study, at least one‑fifth of the patients attending to ED experienced medication errors resulting from multiple factors. More common prescription errors happened during ordering drug dose and frequency. More common administration errors included dug omission or unauthorized drug

The main objective of this study was to assess the effects of pharmaceutical care interventions in patients with essential hypertension in Lakshmi Pat Singhania Institute of Cardiology, Kanpur, India.
MethodsThe study was carried out from July 2010 to August 2011. Pharmaceutical care was provided for 54 patients (intervention group) which was comprised of the patient education, the prescription assistance and the life style modifications and motivation for health. Then the clinical outcome as well as health related quality of life (HRQOL) were compared with the control group (48 patients) in which the pharmaceutical care was not provided. Furthermore, the effect of pharmaceutical care intervention on HRQOL was assessed using Short Form‑36 (SF‑36), a general health related quality of life questionnaire used to evaluate the QOL of patients. Blood pressure (BP) measurements and QOL survey was performed at baseline and at the follow‑up session.
FindingsThe difference between blood pressure readings from the baseline to the second follow‑up was significant for systolic [(P = 0.0001), 12.24 mmHg] and diastolic BP [(P = 0.001), 5.17 mmHg] in the intervention group. The questionnaire used to evaluate the QOL of patients also showed improvement in the mean score for intervention group.
ConclusionResults from our study showed that applying pharmaceutical care to hypertensive patients can help in the control of these patients’ blood pressure, and consequently lower the risk that hypertension poses in cardiovascular disease. Successful implementation of pharmaceutical care has the potential to increase patients’ satisfaction with their pharmacists’ activities and may increase patients’ expectations that pharmacists will work on their behalf to assist them with their healthcare needs.

Methadone poisoning can occur accidentally or intentionally for suicide or homicide purposes. The aim of this study was to evaluate the epidemiological and clinical manifestations of Methadone poisoning.
MethodsA descriptive analytical study was performed from 2010 to 2012 in the poisoning emergency and clinical toxicology departments of Noor hospital affiliated with Isfahan University of Medical Sciences (Isfahan, Iran). All patients with Methadone poisoning within this period of time were investigated. Different variables were recorded in a checklist.
FindingsA total of 385 patients were studied. About 85.7% had ingested only Methadone and 14.3% had ingested other medications with Methadone. Mean ± standard deviation of the age was 32.1 ± 15 years (range: 1‑90). Most of the patients were male (76.4%). Nearly 40% of the patients were narcotic addicts, 25.5% were addicts under surveillance of Methadone maintenance therapy centers and 34.5% were non‑addicts. Intentional poisoning was observed in most of the patients (57.7%). Most of the patients had a low level of consciousness on admission (58.2%). Respiratory depression and hypotension was observed in 35.6% and 12.7% of the cases as the most common symptoms. Regarding vital signs, there was a significant difference in respiratory rate on admission among different evaluated groups (P = 0.02). Length of hospital stay was 18.79 ± 0.72 h (range: 4‑240 h, median: 15 h). About 57 patients (25.8%) from the intentionally poisoned patients and 19 patients (12.3%) from the unintentionally poisoned patients had a history of psychiatric disorder (P = 0.001). Most of the patients survived without complications.
ConclusionAddiction, age, gender, attempt to suicide and a history of psychiatric disorder were of the most important factors effective in Methadone poisoning, which should be considered in the public training and prevention of poisoning
