Aims: Patients with epistaxis typically visit the emergency department for initial treatment. According to recent studies, tranexamic acid (TXA) is effective in the treatment of epistaxis. This study compared the therapeutic superiority of saline to that of 500 and 1000 mg doses of topical TXA for the treatment of anterior epistaxis. Materials and methods: This phase 4 clinical trial was a randomized, controlled, and double-blind trial. A total of 152 patients were divided into three groups. Group 1 was treated with 1000 mg TXA, Group 2 with 500 mg TXA, and Group 3 with saline. Results: Based on multinomial logistic regression analysis, the bleeding frequency at the 5th minute was 2.9 times and rebleeding status was 4.3 times less in Group 1 (1000 mg TXA) than in Group 3 (saline). There were no differences between the three groups in terms of side effects or salvage therapy. Conclusion: In addition to its superiority in treatment, 1000 mg of TXA is recommended because of the decreased rate of recurrent bleeding and low incidence of side effects.
Needle electromyography (EMG) is an expression of the physiological or pathophysiological state of muscles. Selection of the type of electrode used during these measurements is based upon several factors, including the location of the muscle of interest, the need for specificity, and the requirement of minimization of cross-talk between adjacent muscles. Pneumothorax is a serious complication of needle EMG. Here, we present a 19-year-old patient who suffered bilateral pneumothoraces as a complication of needle EMG. She has a history of weakness and limitation of abduction on her right shoulder for three years. EMG was ordered by orthopedic surgeon to determine whether a dorsal scapular or long thoracic nerve paralysis caused these symptoms. She was brought to our emergency department (ED) with the complaints of diaphoresis and dyspnea which began after needle EMG was performed two hours ago. A chest X-ray revealed bilateral small pneumothoraces and was confirmed by computed thoracic tomography scan. Patient was admitted to observation unit in ED. Thoracic ultrasonography was preferred to follow up the patient. After five days, pneumothoraces were dissolved on bilaterally and the patient was discharged to home. Iatrogenic pneumothorax is a complication observed at various clinical fields. Emergency physician must consider this possibility in patients admitted with dyspnea after needle EMG.

We aimed to reveal the anti-convulsant effects sulfasalazine and its mechanism in pentylenetetrazole (PTZ)-induced seizures in rats. Forty-eight male Wistar albino rats (200-250 g) were randomly divided into two groups: 24 for electroencephalography (EEG) recording (group A) and 24 for behavioral studies (group B). About 70 mg/kg PTZ was used for behavioral studies after sulfasalazine administration and 35 mg/kg PTZ was used for EEG recording after sulfasalazine administration. Electrodes were implanted on the dura mater over the left frontal cortex and the reference electrode was implanted over the cerebellum for EEG recording. Racine’s convulsion scale, first myoclonic jerk onset time, spike percentages, brain malondialdehyde (MDA), superoxide dismutase (SOD), and prostaglandin F2α (PGF2α) levels were evaluated between the groups. First myoclonic jerk onset time was significantly shorter in the saline group than both 250 and 500 mg/kg sulfasalazine groups (P<0.05). Racine's convulsion scores were significantly lower in the 250 and 500 mg/kg sulfasalazine groups than the saline group (P<0.05, P<0.001). The two sulfasalazine groups had lower spike percentages than the saline group (P<0.05). Significantly lower MDA and PGF2α levels were observed in the 250 and 500 mg/kg sulfasalazine groups compared with the saline group (P<0.05, P<0.001, respectively). SOD increased significantly in both sulfasalazine groups compared with the PTZ+saline group (P<0.05). Our study demonstrated that sulfasalazine had protective effects on PTZ-induced convulsions by protecting against oxidative and inflammatory damage associated with PTZ.
Objectives: The primary aim of this study was to determine the value of the inferior vena cava (IVC) ultrasound in the decision to hospitalise acute decompensated heart failure (ADHF) patients. Our secondary aim was to find the most successful IVC measurement method in monitoring volume status. Methods: ADHF patients were accepted over a 1-year period in this study. Patients’ vital signs, laboratory tests and IVC measurements measured by six methods (in B- and M-mode; maximum, minimum diameter and caval index) performed on an hourly basis were recorded. The presence of any statistically significant difference between the IVC measurement methods, laboratory tests and vital parameters between the hospitalised and discharged patients was calculated. ROC curves were produced in order to determine the ability of parameters to differentiate two groups. Spearman’s correlation test was used to investigate correlation between the IVC measurement methods and patients’ urine outputs. Results: A total of 71 patients were included in the study; 42 of these were hospitalised and 29 were discharged. Potassium, brain natriuretic peptide, respiration rate, urine output, maximum and minimum IVC diameters differed significantly between the two groups. Minimum IVC diameter measured in M-mode was identified as a weak marker with 65% sensitivity and 64% specificity (+PPV: 73%; −NPV:54%) for hospitalisation. Change in maximum IVC diameter measured in B-mode exhibited a high degree of correlation with change in body fluid (cc: 0.802). Conclusion: IVC ultrasound may have a limited value in the decision to hospitalise ADHF patients. But Maximum IVC diameter may be an ideal method for monitoring hypervolemic patients’ volume status.
