Urolithiasis is one of the most common urological diseases worldwide, usually presenting as renal colic that leads to severe pain that requires analgesic treatment. This study aimed to compare the efficacy of ketamine and desmopressin in the pain management of renal colic patients. Methods This double-blind, randomized clinical trial was conducted on renal colic patients referred to the emergency department from June 2021 to July 2022. Patients were randomly assigned to three groups. In the desmopressin group, patients were treated with intranasal desmopressin and intravenous ketorolac. The ketamine group was treated with intranasal ketamine and ketorolac. The control group received ketorolac and an intranasal placebo. Vital signs were evaluated at baseline and 60 minutes; and pain scores were assessed at baseline, 10, 30, and 60 minutes after treatment. Results Enrollment included 135 patients, the mean (standard deviation) age was 44.1±11.4 years, and 82 (60.7%) were men. The mean visual analog scale scores were significantly lower at 10, 30, and 60 minutes in the ketamine group (5.6±1.2, 3.0±1.1, and 0.9±0.9, respectively) compared to the control (8.2±1.1, 5.1±2.0, and 2.3±2.6, respectively) and desmopressin (6.7±1.8, 4.2±2.2, and 1.3±1.4, respectively) groups (P<0.05). Although patients in the desmopressin group had lower mean pain scores than the control group at 10, 30, and 60 minutes, this difference was only significant at 10 minutes after the intervention (P<0.05). No significant differences in vital signs were found at 60 minutes after treatment. Conclusion Ketamine showed more favorable analgesic effects in renal colic patients than desmopressin, although desmopressin showed efficacy in the first minutes posttreatment.

·AIM: To evaluate correlation of cystatin-C (Cys-C) with severity of diabetic retinopathy (DR) and acute phase reactants, including erythrocyte sedimentation rate (ESR) and high-sensitivity C-reactive protein(hs-CRP). ·METHODS: All diabetic patients who were referred for diabetic retinopathy (DR) screening during 1mo were enrolled. Demographic data were recorded. All patients have undergone full ophthalmic exam. At the same day, all patients were tested for hemoglobin A1c (HbA1c), ESR,hs-CRP,and Cys-C serum levels. · RESULTS: Sixty seven diabetics were enrolled, including 19 (28.3%) without retinopathy, 22 (32.8%) non - proliferative retinopathy, and 26 ( 38. 8%) proliferative retinopathy patients. The mean age, sex distribution, mean duration of diabetes, prevalence of hypertension and dyslipidemia, smoking status and HbA1c levels were not significantly different among the three groups. The mean levels of Cys - C increase significantly as retinopathy progress [1.1 ± 0. 48; 1. 22 ± 0.38;1.71 ± 0.92 (P=0.007), respectively]. In multiple regression analysis, just Cys - C was significantly associated with severity of DR (P=0.025). ·CONCLUSIONS: This study revealed that serum levels of Cys-C increase while DR progress independently of acute phase reactants. Therefore, it could be used as an associated marker by primary care physicians to distinguish patients at higher risk of severe DR. Larger randomized studies are warranted to confirm findings. Reviewing physiological role of the Cys-C, we proposed that the Cys-C may be a protective response to catalytic stress rather than being a pathogenic factor in microangiopathies.

PURPOSETraffic injuries are among the leading causes of mortality and morbidity worldwide. Pedestrians have been considered as a high-risk group among road users, especially in middle- or low-income communities. This study attempted to determine the burden of pedestrians' fatalities in Fars, the southern province of Iran using years of life lost (YLL) approach.

METHODSThe data used in this study were retrieved from Fars Forensic Medicine Organization database on pedestrian traffic accidents. The YLL from 2009 to 2013 was estimated using the method presented by World Health organization. Some epidemiological characteristics of pedestrians' fatalities were analyzed by SPSS.

RESULTSAlthough YLL among 1000 male pedestrians decreased from 2.5 in 2009 to 1.5 in 2013, it increased from 0.9 to 2.1 among 1000 females during the same period. Higher proportion of death was found in female, illiterate, and married pedestrians (p < 0.001). In addition, mortality was higher in pedestrians living the cities, during daytime, at home, and in hospitals (p < 0.001).

CONCLUSIONConsistent with the global trends, burden of pedestrian accidents in Fars was also exceptionally high. Considering the national and cultural aspects of different countries, improving the safety of pedestrians demands a multi-dimensional approach with interventional factors concerning policies, rules, pedestrians, motor vehicles and environmental conditions taken into consideration.
