Objectives: In light of the high prevalence of sleep disorders in patients suffering from posttraumatic stress disorder (PTSD), this study sought to compare the effect of prazosin and hydroxyzine on sleep quality in this patient group. Methods: A total of 100 patients suffering from PTSD were assessed (mean age = 35.51 years, SD = 6.41; 28% females). Next, they were randomly assigned to one of three treatment groups: prazosin (33 patients), hydroxyzine (34 patients) or placebo (33 patients). The trial lasted for 8 weeks. The patients' sleep quality was assessed using the Pittsburgh Sleep Quality Index. Items taken from the Mini International Neuropsychiatric Interview were used to operationalize PTSD. Results: Compared to controls, patients treated with prazosin and hydroxyzine reported improved sleep and less nightmares. Improvement was greatest in patients treated with prazosin compared to hydroxyzine and placebo. Improvement in sleep was associated with an amelioration of their PTSD symptoms. Conclusion: Both prazosin and hydroxyzine can be used to treat psychopharmacological sleep disorders and nightmares in patients suffering from PTSD, also leading to reductions in PTSD symptoms.
Minimizing X-ray exposure during percutaneous nephrolithotomy (PCNL) is challenging. Using the single semirigid dilator, also called "one-shot" or "one-stage" is a good alternative to routine telescopic metal dilators to reduce X-ray exposure. Our aim was to compare the single semirigid one-shot dilator with a telescopic metal dilator in PCNL. The intraoperative status was evaluated in 100 consecutive patients randomly assigned to two equal groups undergoing PCNL either with the one-shot (group A) or telescopic technique (group B). No significant difference in stone burden and location existed between the groups (P > 0.05). The mean age of group A and group B was 44.8 ± 15 and 45.6 ± 14 years, respectively (P = 0.78). The mean operation time was 51.14 ± 40.85 min in group A and 57.00 ± 38.85 min in group B (P = 0.46). The mean X-ray exposure time was 41.2 ± 17 and 48.4 ± 15 s in group A and group B, respectively (P = 0.03). The stone-free rate was 94 % (n = 47) in group A and 84 % (n = 42) in group B (P = 0.10). The mean hemoglobin drop was 1.26 ± 0.09 and 1.44 ± 0.11 g/dl in group A and group B, respectively (P = 0.09). The one-shot technique is feasible, safe, and well tolerated in patients undergoing PCNL. In addition to lack of complications, the method also provides less radiation exposure for urologists and nursing teams.
Introduction:Acute kidney injury (AKI) is one of the most common diseases among the newborns hospitalized in the neonatal intensive care units (NICUs), which is usually resulted from predisposing factors including sepsis, hypovolemia, asphyxia, respiratory distress syndrome (RDS), and heart failure. The goal of this study was to assess main etiologies, relevant risk factors, and early outcome of neonatal AKI.Materials and Methods:In a cross- sectional study, 49 consecutive neonates hospitalized in NICU of Besat hospital with diagnosis of AKI from October 2009 to October 2011 were investigated through census sampling method. AKI was diagnosed based on urine output and serum creatinine levels.Results:The prevalence of AKI was 1.54% (49 out of 3166 newborns hospitalized in NICU) with the female: male was 7:1. Thirty-nine patients (79.5%) were full-term neonates. Oliguria was observed in 38 (77.5%) patients. Sepsis was the most common predisposing factor for AKI in 77.5% of patients (n = 38) accompanied with the highest mortality rate among other factors (30.5%). Other leading causes of AKI included hypovolemia secondary to dehydration, followed by hypoxia secondary to RDS, patent ductus arteriosus, posterior urethral valve, asphyxia, and renal venous thrombosis. A positive relationship was observed between neonates' age, sex, urine output, and also between serum creatinine levels with initiation of dialysis. The mortality rate among the newborns hospitalized with AKI was 36.7%. Eighteen (36.7%) newborns were treated with peritoneal dialysis (PD) of whom 10 patients (55.6%) died, 31 patients were managed conservatively of whom five neonate died (25.9%).Discussion:Prognosis of AKI in the oliguric neonates requiring PD is very poor. It is thus recommended to prevent AKI by predicting and rapid diagnosis of AKI in patients with potential risk factors and also by early and effective treatment of such factors in individuals with AKI.
BackgroundIodinated X-ray contrast media are the most commonly used contrast agents in the world with an annual application of 40-50 million. New non-ionic contrast agents are subdivided into low osmolar agents such as iopromide and iso-osmolar agents such as iodixanol. Regarding different biochemical characteristics, these agents are different in the allergic reactions and contrast enhancement and final lesion conspicuity.ObjectivesThis study was carried out to compare allergic adverse effects and contrast enhancement between iodixanol and iopromide.Patients and MethodsOne-hundred and twenty patients who were referred for abdominal CT scan to Besat Hospital were included in this study. Patients were randomly divided into two groups (A and B). Group A received 100 cc iodixanol (300 mgI/mL) and group B received 100 cc iopromide (300 mgI/ml) by power injector. CT examination was performed using Helical CT Scanner (Somatom, Siemens, Germany). Sixty seconds after injection, images were obtained and enhancement of port, liver and aorta were determined. Allergic adverse effects were recorded one hour and up to one week after injection.ResultsIodixanol produced a significantly greater enhancement of the hepatic, aorta and portal vein than iopromide (P < 0.01). Sixty seconds after injection, associated pain and heat sensation were less frequent in iodixanol in comparison with iopromide (P = 0.03). Immediate reactions such as nausea and vomiting were less frequent in iodixanol (P = 0.01). Late skin reactions such as rash was more frequent in iodixanol (P < 0.01).ConclusionsIodixanol is safe and is better tolerated in the early phase of injection with better contrast enhancement and lesion conspicuity. Mild late skin rash is its disadvantage.
