Validating and assessing the reaction of medical students toward team-based learning
The aim of this study was to evaluate the psychometric properties of tools �Team-Based Learning Student Assessment Tool�, Classroom Engagement Survey (CES) and to assess the reaction of learners toward TBL sessions at Tehran University of Medical Sciences. This descriptive study was done in 2013. The first step was to assess the reliability and validity of the tools. TBL-SAI questionnaire include 39 items, and CES consists 8 items. The validity was assessed through Delphi rounds by experts and reliability, through internal consistency and Test-Retest approach. Then, the reaction of medical students (N=78) was assessed concerning the aspects of team-based learning sessions through TBL-SAI and CES. The data were analyzed through descriptive tests. Our results have study confirmed the TBL-SAI and CEA validity. The tools �reliability was approved through: TBL-SAI Cronbach's alpha=0.79, CES Cronbach�s alpha=0.71 and TBLSAI ICC=0.82, CES ICC=0.75. The result of the second phase showed the TBLSAI scores of participation were appropriate concerning TBL session (159.60�12.89) According to confirmed validity of tools, these can be used in researches related to team-based learning in Iran. It could facilitate assessing the learners� reaction of team-based learning studies at Iranian medical science universities. In the present study, the reaction of students who participate in TBL sessions had been positive and their participation, satisfaction, and accountability had been improved. � 2016 Tehran University of Medical Sciences.

Correlation of clinical signs and symptoms of Behçet�s disease with mean platelet volume (MPV) and red cell distribution width (RDW)
Background: A strong correlation was previously found between mean platelet volume (MPV), red blood cell distribution width (RDW), and the severity of signs and symptoms in patients suffering from inflammatory and autoimmune diseases. The current study evaluated these correlations in patients with Behçet�s disease (BD) as well the relationship between MPV and RDW and disease activity score on the Iranian Behçet�s Disease Dynamic Activity Measurement (IBDDAM). Methods: This cross-sectional study included 319 patients with BD for whom demographic and epidemiological data, IBDDAM scores, and duration of illness was recorded. Blood samples were then obtained and the relationships between their disease status and manifestations and their laboratory parameters were evaluated with statistical models to find possible correlations. Results: Our analysis showed a significantly higher RDW in patients with BD who had ocular manifestations (p < 0.001) and oral aphthae (p = 0.004). Patients with active BD had higher RDW (p < 0.001) and MPV (p < 0.001) in comparison to those with currently inactive BD. Similarly, patients who had any type of ocular manifestation had higher RDW (p < 0.001) and MPV (p < 0.001). Regression analyses identified a statistically significant model for the effect of RDW and MPV in predicting active BD status (p < 0.001), as well as its significant relationship with active ocular manifestations (p < 0.001). Conclusion: BD was found to be associated with an increase in MPV and RDW, particularly during active phases. RDW and MPV were also found to have predictive value for screening to detect BD activity and its ocular complications. © 2020, The Author(s)
Genital ulcer severity score and genital health quality of life in Behçet's disease
Background: Behçet's Disease (BD) is a chronic auto-inflammatory, multisystem relapsing/remitting disorder of unknown aetiology. Oro-genital ulceration is a key feature of the disease and has a major impact on the patients' quality of life. Other clinical manifestations include ocular inflammation, rheumatologic and skin involvement, while CNS and vascular complications can lead to considerable morbidity. The availability of a valid monitoring tool for BD activity is crucial in evaluating the impact of the disease on daily life activity. The aims of this study were to validate a novel tool for monitoring genital ulceration severity in BD and to assess the impact of genital ulcers on the Genital Health Quality of Life (GHQoL). Methods: Genital Ulcer Severity Score (GUSS) was developed using six genital ulcer characteristics: number, size, duration, ulcer-free period, pain and site. A total of 207 BD patients were examined, (137 females: mean age∈±∈SD: 39.83∈±∈13.42 and 70 males: mean age∈±∈SD: 39.98∈±∈11.95) from the multidisciplinary Behçet's Centre of Excellence at Barts Health NHS Trust. GUSS was used in conjunction with Behçet's Disease Current Activity Form (BDCAF). Results: The over-all score of GUSS showed a strong correlation with all genital ulcer characteristics, and the strongest correlation was with the pain domain (r∈=∈0.936; P∈2: 0.600; P∈<∈0.0001). Conclusions: This study established the practicality of GUSS as a severity monitoring tool for BD genital ulcers and validated its use in 207 patients. Genital ulcers of BD have a considerable impact on the patients GHQoL
Dermatoscopic and mucoscopic features of lesions in patients with Behcet's disease
Objective: Behcet's disease (BD), as a vasculitis, can affect small and large vessels. As dermatoscopy has been shown to improve the accuracy in diagnosis of various skin lesions especially vascular patterns, we set this study to find if there is any characteristic pattern in the dermatoscopy of Behcet's mucocutaneous lesions.Methods: This prospective cross-sectional observational study designed to evaluate dermatoscopic features of Behcet's mucocutaneous lesions. Fifty six consecutive patients presenting at the outpatient clinic of the BD Research Unit were included. If present, for each patient one oral, one skin and one genital lesion were evaluated by dermatoscopy. When indicated, pathergy test was performed according to a standard protocol and the results were evaluated by dermatoscopy.Results: A total of 40 oral, 8 genital, 14 skin lesions and 14 pathergy tests were evaluated by dermatoscopy. While vascular component was the most prominent feature in oral aphthae, this component was less prominent in genital lesions. Dot vessels were the most common form of vessels in both oral and skin lesions. All the oral lesions were characterized by a central white structureless area. Skin lesions were characterized by a red structureless background. In pathergy tests, negative pricks showed absence of specific features while positive pricks were characterized by a structureless background in pink, purple or red. No obvious vascular component was detected in any of the pricks.Conclusion: It seems that these findings have no specific clues for the diagnosis of BD, but our study is the first study in this field and the findings may give way to further investigations
