Ketoprofen gel improves low back pain in addition to IV dexketoprofen: a randomized placebo-controlled trial

Objective Oligoanalgesia is common in emergency departments (EDs), and pain management is of concern for ED physicians. The aim of this study was to reveal the effect of ketoprofen gel in patients presenting with mechanical low back pain to the ED. Method All the study patients received intravenous dexketoprofen additional to study drugs. After dexketoprofen, 2 g of 2.5% ketoprofen gel or placebo was administered to the site with pain and tenderness. Pain relief at 15 and 30 minutes was measured by visual analog scale scores. Rescue drug need and adverse effects were also recorded. Results A total of 140 patients were enrolled into the study. The mean age of the study patients was 35 ± 12, and 56% (n = 79) of them were male. The mean pain reduction at 30 minutes was 52 ± 18 for ketoprofen gel and 37 ± 17 for placebo, and ketoprofen gel was better than placebo at 30 minutes (mean difference, 16 mm; 95% confidence interval, 10-21). Ten patients (14%) in the placebo group and 2 patients (3%) in the ketoprofen gel group needed rescue drug (P = .35). Conclusion Ketoprofen gel improves pain in patients presenting with mechanical low back pain to ED at 30 minutes in addition to intravenous dexketoprofen when compared to placebo. © 2016 Elsevier Inc

Sprain to the Emergency Department A Randomized Controlled Study

Objective: Despite the favorable data concerning topical agents use in outpatient clinics, they are not commonly in emergency departments (EDs). The present study aimed to compare the effect of 2.5% topical ketoprofen (gel form) to placebo in children presenting with ankle sprain to the ED.Study Design: Children between 7 and 18 years old presenting with ankle sprain composed the study population. Study patients were randomized into 2 study arms: 2.5% ketoprofen gel and placebo administered in a 5-cm area locally. Pain improvements at 15 and 30 minutes were measured by visual analog scale.Results: Median pain reductions at 15 minutes for ketoprofen and placebo groups were 27.5 (16-39) and 5 (4-10), respectively. Median changes in pain intensity at 30 minutes for ketoprofen and placebo gel groups were 48 (43-52) and 9 (6-16), respectively. When compared 2 arms for the pain improvement at 15 and 30 minutes, the differences between 2 study drugs were 20 (13-28) and 35 (29-41), respectively. There were 7 (12.7%) rescue drug needs in the placebo group and 1 (1.7%) in the ketoprofen group ( difference, 10.9%; 95% confidence interval, -6% to 7%; P = 0.83). There were no adverse effects in either group.Conclusions: Ketoprofen gel is superior to placebo in ceasing pain in children presenting with ankle sprain to the ED with a high safety profile.C1 [Serinken, Mustafa] Pamukkale Univ, Dept Emergency Med, Med Fac, Denizli, Turkey.[Eken, Cenker] Akdeniz Univ, Dept Emergency Med, Med Fac, Antalya, Turkey.[Tunay, Kamil] Afyon Kocatepe Univ, Dept Emergency Med, Med Fac, Afyon, Turkey.[Golcuk, Yalcin] Manisa Celal Bayar Univ, Dept Emergency Med, Med Fac, Manisa, Turkey

Distinguishing Right Ventricular Cardiomyopathy From Idiopathic Right Ventricular Outflow Tract Tachycardia with T-wave Alternans

Background: The 2 predominant etiologies of right ventricular tachycardia (VT) are arrhythmogenic right ventricular cardiomyopathy (ARVC) and idiopathic VT arising from the right ventricular outflow tract. Discrimination between these 2 entities is critical, as their prognoses and therapeutic options differ. The microvolt T-wave alternans (TWA) is widely used to predict lethal ventricular arrhythmias in various diseases. However, the clinical significance of TWA in patients with VT originating from the right ventricle has been unknown. This study aims to investigate the possible role of TWA to discriminate ARVC from idiopathic right ventricular outflow tract tachycardia (RVOT-VT). Methods: This study enrolled 38 patients (23 male, 43 +/- 16 years) with VT originating from the right ventricle. TWA was measured during exercise testing using the modified moving average method. TWA results were compared among patients with ARVC and RVOT-VT. Results: Twenty-five patients (16 male, 42 +/- 16 years) met the Task Force criteria for the diagnosis of ARVC, and 13 patients (7 male, 45 +/- 14 years) had idiopathic RVOT-VT. Twenty patients with ARVC had positive TWA test, whereas only 1 patient with RVOT-VT had (80% versus 8%, P < 0.001). Conclusions: In patients with VT of right ventricle origin, positive TWA test supports the diagnosis of ARVC

Fluorescence Reduction in Raman Spectroscopy by Chemical Bleaching on Renal Stones

In this study, a hydrogen peroxide-based chemical bleaching technique was applied on two different types of renal stones. The characterization was achieved after the bleaching process. They were identified as calcium phosphate and calcium oxalate monohydrate. The samples were analyzed using dispersive Raman spectroscopy with a 532-nm excitation laser. To compare the results, the samples were measured using both FT-IR and FT-Raman spectroscopy. Consequently, the mineral/matrix ratio of Raman bands changed for both samples, but without any noticeable frequency shifts in the Raman spectra
