- چکیده:
- چکیده انگلیسی: Cyclosporine (CsA) is a drug that has been used for prevention of kidney transplant rejection for many years. Diltiazem with the inhibition of cyclosporine metabolism and clearance will increase CsA concentration and CsA dose can be decreased. The aim of this study was the evaluation of diltiazem effect on CsA dose adjustment with respect to C2. Forty stable renal transplant patients who were receiving CsA, prednisolone, mycophenolate mofetile as well as diltiazem were enrolled in the study. At first, minimum concentration of CsA (C0) and concentration within 2 h after dosing (C2) were determined in every patient. These patients were randomly assigned to an 8-week period of continued therapy with diltiazem (20 patients), or to a washout period removing diltiazem from the treatment (20 patients). At the end of this period, CsA concentrations were measured. Thereafter, the groups underwent a crossover followed by either diltiazem washout or reinstituted treatment with diltiazem. Then C0 and C2 were measured. In each step which diltiazem was removed from patient drug regimen, CsA dose was increased by 25%. Finally, we detected that this amount of CsA dose adjustment is suitable in our patients and C0 and C2 remained in the therapeutic windows. Diltiazem co-administration with CsA will be safe and cause decreased patients drug cost.

- چکیده:
- چکیده انگلیسی: Adverse drug reaction (ADR) is one of the most life threatening problems, and the economic burden of ADR is considerable. The main objective of this study was to assess the attitude of the Kerman health system staff, to evaluate their knowledge of the spontaneous reporting system and to identify the reasons for low reporting rate. In this descriptive study, a Persian translated questioner was used based on standard European pharmacovigilance research group. Among 800 distributed questionnaires, 78% were filled and returned. Returned questioner (82%) indicated to have already suspected an ADR but only 4% reported it to Iranian ADR centre. The 4 major reasons for not reporting were: a) reporting process was unknown (65%), b) Iranian pharmacovigilance centre was unknown for the staff (45%), c) the yellow cards for reporting ADR were not available (30%), and d) ADR were not important (22%). We concluded that our medical staff's knowledge about ADR is little. Appropriate teaching and acceptable effort is needed to strengthen the current system and to prevent other serious ADRs.

- چکیده:
- چکیده انگلیسی: The aim of this study was to investigate the prevalence of Mg deficiency and effect of aminophylline infusion on urine magnesium concentration after magnesium loading test (MLT). To determine serum Mg, venous blood specimens were obtained just before the first MLT. Two MLTs were performed. The first one was done before starting aminophylline infusion and the 2nd one was done during aminophylline infusion. Urine samples were collected from the starting of Mg infusion in each phase. Although low serum Mg was present only in 2 patients, MLT showed Mg deficiency in 18 patients. MLT detected Mg deficiency in 13 out of 14 patients with normal serum Mg, in 2 out of 2 subjects with serum hypomagnesemia, and in 3 out of 5 cases with serum hypomagnesemia. There was no relationship between Mg retention, age and serum Mg concentrations. Aminophylline administration increased the 24-h urine Mg concentration by 29.3%.

- چکیده:
- چکیده انگلیسی: Nearly 15% to 25% of patients in general hospitals have a catheter at some time
during their stay. Up to 97% of nosocomial urinary tract infections (UTIs) are related
to catheter. The type of bacteremia is usually polymicrobial which makes the treatment
more difficult. Previous studies showed an increase in mortality from bacteremia in these
patients. The aim of the present study was to compare the prevalence of UTIs among
patients with and without catheter, and to detect the type of bacteriuria and antibacterial
resistance pattern.
In this cross sectional study, samples were taken between Jan 2011 and July 2011. 678
hospitalized patients in different wards of Afzalipour hospital, Kerman- Iran, were enrolled in
the study. E-test was applied to detect the pattern of resistance to gentamicin, nitrofurantoin,
ciprofloxacin, ceftriaxon and co-trimoxazole. Results showed positive culture samples in 86%
of female patients.
Escherichia coli, Candida and Staphylococcus aureus were detected in 72, 20 and 7 percent
of the positive cultures, respectively. 52.3% of detected E.coli was sensitive to gentamicin , 62%
to ceftriaxone, 71.4% to ciprofloxacin, and 91.9% were sensitive to nitrofurantoin. Therefore,
the most sensitive antibiotics in UTIs were ciprofloxacin and ceftriaxone. Unfortunately, the
rate of antibacterial drug resistance was high in comparison with developed countries. Wise
selection of antibiotics at hospitals and increasing the knowledge of patients to prevent self use
of antibiotics can reduce antimicrobial resistance.- انتشار مقاله: 12-02-1391

- چکیده:
- چکیده انگلیسی: Background: Few studies have been conducted regarding the comparison of the efficacy of methadone and
tincture of opium (TOP) in controlling agitation induced by withdrawal syndrome. Therefore, the current
randomized trial study is carried out with the aim to evaluate comparisons on the efficacy of methadone and
TOP in controlling agitation caused by withdrawal syndrome in opium addicted patients in the intensive care
units (ICUs).
Methods: This clinical trial study was conducted on 60 patients admitted to ICU of Shahid Bahonar Hospital,
Kerman, Iran. After classification of the patients into two groups, the first and second groups consumed
methadone syrup (5 mg/ml) and TOP (10 mg/ml), respectively. Agitation in these patients was assessed
through the Richmond Agitation-Sedation Scale (RASS). Vital signs were also assessed. Paired sample t-test
and independent t-test were used for data analysis.
Findings: In the current study, the administered dose of methadone and TOP was 36.17 ± 26.99 and
112.67 ± 102.74 mg, respectively (P < 0.010). Methadone administration led to a significant decrease of the
patients’ vital signs, including systolic blood pressure, heart rate, respiratory rate, and Glasgow Coma Scale
(GCS) (P < 0.05). Though TOP administration decreased systolic blood pressure and GCS significantly
(P < 0.05), it had no effect on patients’ diastolic blood pressure, body temperature, heart rate, and
respiratory rate (P > 0.05). In total, no significant difference was detected between two groups regarding
vital signs (P > 0.05). However, a significant difference was seen between methadone and TOP groups in
terms of RASS score (P < 0.01).
Conclusion: According to the results of the current study, lower dose of methadone, compared to TOP, could
control agitation caused by opium withdrawal symptoms.
