Endoscopic-assisted Orbitotomy for Obliteration of Orbital Arteriovenous Fistula Refractory to Endovascular Techniques.

Orbital arteriovenous fistula is a rare acquired disorder. The coincidence of arteriovenous fistula with lymphaticovenous malformation is even rarer. The optimal treatment, thus, is controversial. Surgical approaches vary widely, with associated pros and cons. The purpose of this case report is to describe an orbital arteriovenous fistula in a 25-year-old man with congenital fronto-orbital lymphaticovenous malformation, refractory to endovascular techniques, which was later successfully ablated by a direct endoscopic-assisted orbital approach.

NONARTERITIC ANTERIOR ISCHEMIC OPTIC NEUROPATHY ASSOCIATED WITH IPSILATERAL HYPOPLASTIC INTERNAL CAROTID ARTERY.

BACKGROUND: Vascular insufficiency of the optic nerve head is the cause of nonarteritic ischemic optic neuropathy (NAION). Carotid artery abnormalities are now considered as a predisposing factor for developing NAION. In this report, we present a case of NAION associated with ipsilateral internal carotid artery hypoplasia. METHODS: A 69-year-old female with decreased vision in her right eye due to NAION was evaluated. the magnetic resonance imaging showed a considerably smaller left internal carotid artery than the right side. The magnetic resonance angiography confirmed the disparity and perfusion abnormalities of intracranial carotid arteries. RESULTS: The diagnosis of left internal carotid artery hypoplasia was made and verified by depicting a left side small carotid canal on the computed tomography scan. CONCLUSION: This report suggests that internal carotid artery hypoplasia could be associated with NAION.

Vitamin E and ginseng supplementation to enhance female sexual function: a randomized, double-blind, placebo-controlled, clinical trial.

Female sexual disorders (FSD) are a spectrum of disorders common among women, especially in their middle age, which can reduce the female quality of life substantially. We aimed to evaluate the effects of a combined vitamin E and ginseng supplement on amelioration of female sexual dysfunction. In a 6-week, double-blind, randomized, placebo-controlled clinical trial, participants, suffering from sexual dysfunction based on the female sexual function index (FSFI) questionnaire, were randomly allocated to receive the supplement (100 IU vitamin E, 67 mg Korean ginseng, and 40 mg Siberian ginseng) or placebo daily. The primary outcome in our trial was the change in the FSFI total score. Sixty-nine participants were enrolled, but only 31 in each group completed the trial. Changes in the FSFI total score and its domain scores were significant during the trial course within each group. However, the supplement only ameliorated desire and satisfaction domains superior to the placebo. In case of the total score and other domains, the changes were insignificantly different between the treatment groups. Although our study could not find additional benefits for the vitamin E and ginseng supplement over placebo in enhancing sexual function overall, the supplement worked better in enhancing sexual desire and satisfaction.

Vortioxetine effects on quality of life of irritable bowel syndrome patients: A randomized, double-blind, placebo-controlled trial.

WHAT IS KNOWN AND OBJECTIVE: Irritable bowel syndrome (IBS) is a functional gastrointestinal disease causing a substantial productivity loss with no definite treatment. Our study investigates the effects of vortioxetine vs placebo in enhancing the IBS patients' quality of life. METHODS: In a double-blinded, placebo-controlled, randomized trial, adults with IBS, according to the ROME IV criteria, were randomized to placebo and vortioxetine for 6 weeks. Participants were visited every two weeks to fill IBS quality of life, hospital anxiety and depression scale, and adverse effect questionnaires. RESULTS: Eighty patients were randomized, and seventy-two finished the trial. Baseline characteristics of groups were similar. Both placebo and vortioxetine significantly increased the quality of life during course of the study (both P-values < .001), whereas vortioxetine demonstrated a greater increase (P-value < .001). According to the analysis of covariances, this enhancement was irrespective of depression or anxiety score changes (P-value = .002). Adverse effect profile was similar between the groups and can increase IBS patients' quality of life superior to placebo. Vortioxetine effects in our study were observed irrespective of the depression and anxiety levels.

Psychometric properties of Persian version of the research misconduct questionnaire (PRMQ).

Assessment of scientific misconduct is considered to be an increasingly important topic in medical sciences. Providing a definition for scientific research misconduct and proposing practical methods for evaluating and measuring it in various fields of medicine discipline are required. This study aimed at assessing the psychometric properties of Scientific Research Misconduct-Revised (SMQ-R) and Publication Pressure Questionnaires (PPQ). After translation and merging of these two questionnaires, the validity of the translated draft was evaluated by 11-member expert panel using Content Validity Index (CVI) and Content Validity Ratio (CVR). Reliability of the final questionnaire, completed by 100 participants randomly chosen from medical academic members, was assessed by calculating Cronbach's alpha coefficient. The final version was named Persian Research Misconduct Questionnaire (PRMQ) and consisted of 63 question items. The item-level content validity indices of 61 questions were above 0.79, and reliability assessment showed that 6 out of 7 subscales had alpha values higher than 0.6. Hence, PRMQ can be considered an acceptable, valid and reliable tool to measure research misconduct in biomedical sciences researches in Iran.

Fluvoxamine combination therapy with tropisetron for obsessive-compulsive disorder patients: A placebo-controlled, randomized clinical trial.

BACKGROUND: About 50% of obsessive-compulsive disorder patients still suffer significant symptoms even after the recommended first-line therapy. This demonstrates the necessity to investigate strategies to improve alleviation of symptoms. OBJECTIVE: The main objective of this study was to investigate the efficacy of a 5-hydroxytryptophan 3 receptor antagonist, tropisetron, as an adjuvant therapy to selective serotonin reuptake inhibitors, in ameliorating obsessive-compulsive disorder symptoms. METHODS: Men and women between the ages of 18-60 years diagnosed with obsessive-compulsive disorder, based on DSM5, who had a Yale-Brown obsessive compulsive scale score of more than 21 were recruited in a double-blinded, parallel-group, placebo-controlled, clinical trial of 10 weeks to receive either tropisetron (5 mg twice daily) and fluvoxamine (100 mg daily initially followed by 200 mg daily after week 4) or placebo and fluvoxamine. The primary outcome of interest in this study was the Yale-Brown obsessive compulsive scale total score decrease from baseline. RESULTS: One hundred and eight participants were equally randomized into two groups; 48 participants in each group finished the trial. The Yale-Brown obsessive compulsive total score significantly dropped in both groups while the tropisetron group participants experienced a significantly higher decrease in their scores (Greenhouse-Geisser F(1.53-65.87)=3.516, p-value=0.04). No major adverse effect was observed in any of the groups. CONCLUSION: This trial showed a significant efficacy for tropisetron over placebo in treatment of obsessive-compulsive disorder symptoms when added to fluvoxamine.
