Relationship between using cell phone and the risk of accident with motor vehicles: An analytical cross-sectional study

Purpose: Traffic accidents are one of the major health problems in the world, being the first cause of burden of illness and the second leading cause of death in Iran. The Sistan-Baluchestan province is one of the most accidental provinces of Iran with the highest rate of accidents-caused deaths. This study was conducted to determine the risk factors associated with traffic accidents in Zahedan through 2013 to 2016. Methods: This analytical cross-sectional study was carried out on 223 drivers from Zahedan who were traumatized by traffic accident and sent to Zahedan hospitals. The data were obtained through interviews taken by the trained interviewers via refereeing to the medical records and collected in the researcher-made checklist. Census was obtained from the study subjects. For data analysis, independent t-test, one-way ANOVA, Chi-square and logistic regression were used with the Stata software version 11.0. Results: In this study, 223 male subjects with the mean age of (32.54 ± 12.95) years, 39.8% single and 60.2% married, entered for investigation. Most accidents (38.8%) occurred between 12:00 to 17:59. While driving, 47.1% of the study subjects were using cell phones, 89.1% had manual use of mobile phones, 21.9% had a habit of sending short message service (SMS) and 23.4% had sent SMS within 10 min before the accident. The one way analysis of variance showed that the mean age of individuals with marital status, driving experience, education and accident with motorcycle were significantly different (p < 0.05). Also, the multivariate logistic regression test indicated a significant relationship of smoking, ethnicity, insurance and SMS typing while driving with motorcycle accident (p < 0.05). Conclusion: In this study, SMS and smoking while driving had the highest risk among the variables studied in the motorcycle accidents. Therefore, effective education attempting to enhance people''s awareness about the consequences of using cell phone and smoking during driving to reduce traffic accidents seems necessary.     

Autoimmune diseases in myelodysplastic syndrome favors patients survival: A case control study and literature review

Background

We conducted a monocentric retrospective study of patients with myelodysplastic syndromes (MDS) and autoimmune or inflammatory disorders (AIMs) and a literature review. We analyzed the association with subgroups of the WHO 2016 MDS classification and patient's survival in a case control study. Risk factors associated with survival were analyzed by uni- and multivariate analysis.

Immunological and In-Vivo Neurological Studies on a Benzoic Acid-Specific T-Cell-Derived Antigen-Binding Molecule from the Serum of a Toluene-Sensitive Patient

T-cell-derived antigen-binding molecules (TABMs) specific for benzoic acid were isolated from the serum of a toluene-sensitive patient. The resulting purified TABMs (BA-TABMs) did not contain immunoglobulin G and were associated with the cytokine transforming growth factor-β (TGF-β). BA-TABMs bound to benzoic acid conjugated to human serum albumin (BA-HSA), as well as to other chemicals conjugated to human serum albumin—including dinitrophenol and oxazolone. The binding of BA-TABMs to the conjugated chemicals increased the level of detectable TGF-β, and a similar effect was observed with the unconjugated chemicals, benzoic acid and 2,4-dinitrophenol glycine. The increase in TGF-β was critically dependent on the ratio between BA-TABMs and the conjugated or unconjugated chemicals; the increase was optimum at intermediate concentrations and absent at low and high concentrations. The authors used an established animal model in vivo and demonstrated that TGF-β enhanced the inflammatory response induced by the release of neuropeptides from sensory nerves; this enhancement occurred in a dose-dependent manner. The BA-TABMs also enhanced this neurogenic inflammatory response in a dose-dependent manner, and this effect was blocked by anti-TGF-β antibody. When the authors added either BA-HSA or benzoic acid, the effect of BA-TABMs on neurogenic inflammation was further enhanced at intermediate concentrations of antigen and was unaltered or reduced at higher concentrations. TABMs specific to particular chemicals, as a result of their association with cytokines (e.g., TGF-β), may be implicated in symptom production in chemically sensitive patients.     

Preclinical coronary endothelial dysfunction in Egyptian Behçet’s disease patients; Tc-99m sestamibi pharmacological Gated-SPECT,is it a useful screening tool?

IntroductionBehçet’s disease (BD) is an idiopathic multisystem disorder. Cardiac involvement[cardio-BD] occurs in 7–60% of BD patients. Technetium 99m-Methoxyisobutyl isonitrile (Tc-99m sestamibi) is a myocardial perfusion imaging agent that is used for evaluation of the coronary flow.Aim of the workTo evaluate the usefulness of Dipyridamole pharmacological stress test in conjunction with Tc-99m sestamibi cardiac gated single photon emission computed tomography (GSPECT) to investigate the prevalence of subclinical coronary endothelial dysfunction[SCED] in asymptomatic Egyptian BD patients; also to assess possibly associated clinical predictive variables.Patients and MethodsTwenty-five BD patients without overt cardiac involvement and fifteen healthy controls matched for age, BMI and sex were included. Database included full history, clinical examination, relevant laboratory tests, and Tc-99m sestamibi myocardial GSPECT with coronary angiography[CAG] in GSPECT positive cases. Disease activity was assessed using Behçet’s Disease Current Activity Form (BDCAF).ResultsSCED detected by reduced flow or left ventricular dysfunction (LVD) or both was found in 13/25[52%] of BD-patients[12 males and 1 female] vs. 1/15[6.7%] of controls[P < 0.0001] with normal CAG. Subjects with positive GSPECT had significantly older age[P = 0.01] and longer disease duration (P = 0.02) and were more frequently males (P < 0.0001) than those with negative GSPECT. No statistically significant differences between cases with negative and positive GSPECT were found regarding other clinical or laboratory parameters.ConclusionTc-99m sestamibi GSPECT could be a useful screening tool for detection of SCED in BD patients, so early prophylactic measures and therapy modifications could be considered.     

Topical Corticosteroids and Hospital Length of Stay in Children with Eczema Herpeticum

Abstract: There is concern that the use of topical corticosteroids in patients with eczema herpeticum may facilitate dissemination of herpes simplex virus and worsen disease. Our primary aim therefore was to determine whether topical corticosteroid use in children hospitalized with eczema herpeticum is associated with longer hospital length of stay (LOS). We performed a multicenter retrospective cohort study of 1,331 children ages 2 months to 17 years admitted with a diagnosis of eczema herpeticum between January 1, 2001, and March 31, 2010, to 42 tertiary care children’s hospitals in the Pediatric Health Information System database. Multivariable linear regression models determined the association between receipt of topical corticosteroid therapy on the first day of hospitalization and the main outcome measure: LOS. Receipt of topical corticosteroid therapy on day 1 of hospitalization was not associated with a longer LOS on unadjusted or multivariable analysis (p = 0.75). Receipt of topical calcineurin inhibitors during the hospitalization was also not associated with a longer LOS (p = 0.12). Receipt of systemic corticosteroids was associated with an 18% adjusted longer LOS (95% confidence interval 2%–36%; p = 0.03). Further study is needed to identify which children with eczema herpeticum may benefit from topical corticosteroids, but their use during active infection is not associated with poorer outcomes, although the use of systemic corticosteroids was associated with a longer LOS and should be avoided in patients with eczema herpeticum pending future prospective study.     

Primary Antibiotic Resistance to Helicobacter pylori Strains Isolated From Children in Northern Iran: A Single Center Study

Background:

Initial resistance to antibiotics is the main reason for the failure of Helicobacter pylori (H. pylori) eradication in children.

Objectives:

As we commonly face high antibiotic resistance rates in children, we aimed to determine the susceptibility of H. pylori to common antibiotics.

Patients and Methods:

In this cross-sectional in vitro study, 169 children younger than 14 years with clinical diagnosis of peptic ulcer underwent upper gastrointestinal endoscopy. Biopsy specimens from stomach and duodenum were cultured. In isolated colonies, tests of catalase, urease, and oxidase as well as gram staining were performed. After confirming the colonies as H. pylori, the antibiogram was obtained using disk diffusion method.

Results:

Culture for H. pylori was positive in 12.3% of the specimens, urease test in 21.3%, serological test in 18.9% and stool antigen test was positive in 21.9%. We could show high specificity but moderate sensitivity of both histological and H. pylori stool antigen tests to detect H. pylori. The overall susceptibility to metronidazole was 42.9%, amoxicillin 95.2%, clarithromycin 85.7%, furazolidone 61.9%, azithromycin 81.0%, and tetracycline 76.2% with the highest resistance to metronidazole and the lowest to clarithromycin.

Conclusions:

In our region, there is high resistance of H. pylori to some antibiotics including metronidazole and furazolidone among affected children. To reduce the prevalence of this antibiotic resistance, more controlled use of antibiotics should be considered in children.     

Is membrane sweeping beneficial at the initiation of labor induction?

Objective: To determine whether cervical membrane sweeping during labor induction is beneficial.

Methods: Outcomes of labor after induction in pregnant women at term were compared in a randomized trial. Women were assigned to having their membranes “swept” or “not swept” at the initiation of labor induction.

Results: We recruited a total of 870 women of which 70 were excluded. There were 400 nullipara (Group A) [198 “swept”, 202 “not swept”] and 400 multiparas (Group B) (201 “swept” and 199 “not swept”]. Among group A who received intravaginal prostaglandin (PG) E₂, those who had simultaneous sweeping had significantly shorter mean induction-labor interval (12.9?±?1.3 versus 16.2?±?1.1 hours, p?=?0.046), lower mean dose of oxytocin (6.6?±?0.6 versus 10.11?±?1.4?mU/minute, p?=?0.01), and increased normal delivery rates (vaginal delivery 82.8% versus 58.6%, p?=?0.01). Sweeping also had a favorable effect on nulliparas who had ARM and received oxytocin alone (mean induction-labor interval 5.9?±?2.9 versus 10.9?±?2.6 hours p?=?0.04, mean maximum dose of oxytocin 9.8?±?1.1 versus 15.2?±?1.1?mU/min, p?=?0.01). These results were restricted to women with unfavorable cervix in Group A those who had membrane sweeping.

Conclusion: Membrane sweeping, has beneficial effects on labor and delivery, which is limited to nulliparas with unfavorable cervix requiring PGE₂ or Oxytocin alone.     

Topical Tranexamic Acid Compared With Anterior Nasal Packing for Treatment of Epistaxis in Patients Taking Antiplatelet Drugs: Randomized Controlled Trial

Objective

We evaluated the efficacy of topical application of the injectable form of tranexamic acid (TXA) compared with anterior nasal packing (ANP) for the treatment of epistaxis in patients taking antiplatelet drugs (aspirin, clopidogrel, or both) who presented to the emergency department (ED).

Methods

A randomized, parallel‐group clinical trial was conducted at two EDs. A total of 124 participants were randomized to receive topical TXA (500 mg in 5 mL) or ANP, 62 patients per group. The primary outcome was the proportion of patients in each group whose bleeding had stopped at 10 minutes. Secondary outcomes were the rebleeding rate at 24 hours and 1 week, ED length of stay (LOS), and patient satisfaction.

Results

Within 10 minutes of treatment, bleeding was stopped in 73% of the patients in the TXA group, compared with 29% in the ANP group (difference = 44%, 95% confidence interval, 26% to 57%; p < 0.001). Additionally, rebleeding was reported in 5 and 10% of patients during the first 24 hours in the TXA and the ANP groups, respectively. At 1 week, 5% of patients in the TXA group and 21% of patients in the ANP group had experienced recurrent bleeding (p = 0.007). Patients in the TXA group reported higher satisfaction scores (median [interquartile range {IQR}], 9 [8–9.25]) compared with the ANP group (median [IQR] = 4 [3–5]; p < 0.001). Discharge from the ED in <2 hours was achieved in 97% of patients in the TXA group versus 13% in the ANP group (p < 0.001). There were no adverse events reported in either group.

Conclusions

In our study population, epistaxis treatment with topical application of TXA resulted in faster bleeding cessation, less rebleeding at 1 week, shorter ED LOS, and higher patient satisfaction compared with ANP.
