Unusual Subcutaneous Presentation of Cavernous Hemangioma in the Lower Eyelid: A complete translation from Farsi

This article is based on a study first reported in Farsi in the Bina Journal of Ophthalmology, titled معرفی یک مورد همانژیوم کاورنوس پلک تحتانی, Volume 23, Issue 2 (Winter 2018) 2018/10/23. Original URL: https://binajournal.org/article-1-936-fa.pdf Purpose: To report a patient with cavernous hemangioma (CH) presenting as a “subcutaneous” lower eyelid mass. Case report: A 37-year-old man presented with a painless and palpable mass over the right lower eyelid for two years prior to referral. Computed tomography scan revealed a well-defined, lobulated mass located in the mid and lateral portion of the lower eyelid that extended posteriorly to the anterior orbital space. A transcutaneous excisional biopsy was performed. Histopathologic findings of the tumor confirmed CH. Most CHs are intraconal lesions, making our case an unusual presentation for this condition. Conclusion: CH may present superficially in the eyelid and anterior orbital area and thus, although this location is not common, it should be kept in mind as a differential diagnosis for any well-defined eyelid tumor

Impressions of Participants in a Chemical Mass Casualty Exercise

A mass casualty exercise was performed to investigate triage and decontamination of patients exposed to an irritant gas. Nursing students participated in two groups: emergency department triage (ED) and decontamination (DECON). While participants felt overall that the experience was valuable, DECON participants had a greater interest in emergency response and were more likely to volunteer again

Development and Initial Psychometric Evaluation of the Computer-Based Prostate Cancer Screening Decision Aid Acceptance Scale for African-American Men

BACKGROUND: To reliably evaluate the acceptance and use of computer-based prostate cancer decision aids (CBDAs) for African-American men, culturally relevant measures are needed. This study describes the development and initial psychometric evaluation of the 24-item Computer-Based Prostate Cancer Screening Decision Aid Acceptance Scale among 357 African-American men. METHODS: Exploratory factor analysis (EFA) with maximum likelihood estimation and polychoric correlations followed by Promax and Varimax rotations. RESULTS: EFA yielded three factors: Technology Use Expectancy and Intention (16 items), Technology Use Anxiety (5 items), and Technology Use Self-Efficacy (3 items) with good to excellent internal consistency reliability at .95, .90, and .85, respectively. The standardized root mean square residual (0.035) indicated the factor structure explained most of the correlations. CONCLUSIONS: Findings suggest the three-factor, 24-item Computer-Based Prostate Cancer Screening Decision Aid Acceptance Scale has utility in determining the acceptance and use of CBDAs among African-American men at risk for prostate cancer. Future research is needed to confirm this factor structure among socio-demographically diverse African-Americans

A New Technique Employing Direct Tactile Pressure on the common Carotid Artery to Relieve Acute Episode Attack of Migraine Headache: A Single-Arm Interventional Study

Introduction: Migraine, is a common neurological disorder, and its pathology and acute treatment has not been determined so far. In the contemporary literature, there is no remedy that can abort an acute episode of migraine. Objective: We aimed to evaluate the effect of transient presser on the middle part of common carotid artery for terminating an acute attack of migraine headache. Methods: It is an interventional study without a control limb, performed on patients within age range of 18-45 years. Patients with established migraine headache based on International Classification of Headache Disorders (ICHD) guidelines, who had no atheromatous plaque in their common carotid arteries were included. Pain intensity was evaluated by Universal Pain Assessment Tools (UPAT). In safe position, applying vital signs monitoring and ipsilateral of headache, a gentle pressure was applied on the common carotid artery, lateral to the cricothyroid membrane and medial border of the Sterno-Cleido-Mastoid (SCM) muscle, by using both index and middle fingers, till the headache was relieved, following which the pressure was maintained for a period of 15 seconds. Then the middle finger was maintained at its position and the index finger slid caudally with the same pressure as far a distance of four centimeters and the pressure withdrawn slowly. After 2 minutes, patients were asked to report any change in headache which was recorded. Results: Totally, 215 patients entered this study. The mean of pain score before and after using the technique regarding to UPAT, was 6.28±1.34 and 0.4±0.64, respectively; Also, the pain decreases equal 5.88 score was significant, special by according sex (p<0.001). No side effect was seen. Conclusions: It seems that pressure on the common carotid artery and extending the pressure caudally, helped a rapid, safe and significant reduction in pain score for patients with acute attack of migraine headache

Evaluation of breast cancer risk factors for using in hormone replacement therapy of corticosteroid- treated post-menopausal women

اساس درمان بعضی از بیماری های پوستی و تعدادی از بیماری های دیگر مثل بیماری های خود ایمنی استفاده از کورتیکوستروئید سیستمیک می باشد. این درمان سبب اوستئوپروز و عوارض دیگری به خصوص در خانم های یائسه می شود. درمان جایگزینی با هورمون (HRT=Hormone Replacement Therapy) به منظور پیشگیری و کاهش این عوارض در این گروه از بیماران توصیه شده است. در مقابل HRT سبب افزایش خطر ابتلا به سرطان پستان می شود. در این مطالعه با بررسی عوامل خطر سرطان پستان، عوامل مؤثر در به کارگیری یا عدم به کارگیری HRT در زنان یائسه دریافت کننده کورتیکوستروئید شناسایی گردید. این مطالعه از نوع گذشته نگر بود و در آن 176 بیمار شناخته شده مبتلا به سرطان پستان توسط پاتولوژی انتخاب شدند و به همین تعداد افراد سالم به صورت تصادفی انتخاب گردیدند. اطلاعات لازم مربوط به این دو گروه از طریق مصاحبه حضوری و تکمیل پرسشنامه جمع آوری گردید و مورد تجزیه و تحلیل آماری قرار گرفت. طبق این مطالعه عوامل خطر ابتلاء به سرطان پستان به ترتیب اهمیت عبارت بودند از: سابقه فامیلی، یائسگی دیررس، تاخیر در اولین حاملگی، مدت کم شیردهی، تعداد فرزند کمتر از 2 و عدم بارداری، در مورد سابقه سقط و سن اولین قاعدگی با خطر بروز سرطان پستان رابطه معنی داری یافت نشد. با توجه به نتایج حاصله توصیه می شود که از انجام HRT در بیماران یائسه دریافت کننده کورتیکوستروئید و دارای سابقه فامیلی مثبت سرطان پستان خودداری شود و در مورد فاکتورهای یائسگی دیررس، تاخیر در اولین حاملگی، مدت کم شیردهی تعداد فرزند کمتر از 2 و عدم بارداری، HRT با احتیاط زیاد صورت گیرد

Development and Psychometric Properties of a Prostate Cancer Knowledge Scale for African American Men

African American men have the highest prostate cancer-related mortality nationally. In response to this disparity, targeted interventions are emerging to enhance African American men\u27s prostate cancer (PrCA) knowledge to ensure they are equipped to make informed decisions about PrCA screening with health-care providers. African American men\u27s PrCA knowledge has been measured inconsistently over time with limited psychometric evidence. The factor structure of this construct in African American men is relatively unknown. This study describes the development and psychometric evaluation of an 18-item Prostate Cancer Knowledge Scale among 352 African American men. Exploratory factor analysis (EFA) was conducted using weighted least square mean and variance estimation with Geomin rotation. EFA yielded three factors: (6 items), (5 items), (7 items) with good internal consistency reliability at KR-20 = .80 for the total scale and .64, .66, and .75, respectively, for each subscale. Factor loadings ranged from .31 to .86. The standardized root mean square residual (0.08) indicated that the factor structure explained most of the correlations. The three-factor, 18-item Prostate Cancer Knowledge Scale demonstrates that PrCA knowledge is a multidimensional construct and has utility for reliably measuring PrCA knowledge among African American men. Future research is required to confirm this factor structure among socio-demographically diverse African Americans

Evento de blanqueamiento masivo en la zona norte del Gofo Pérsico, 2012

Coral bleaching events due to elevated temperatures are increasing in both frequency and magnitude worldwide. Mass bleaching was recorded at five sites in the northern Persian Gulf during August and September 2012. Based on available seawater temperature data from field, satellite and previous studies, we suggest that the coral bleaching threshold temperature in the northern Persian Gulf is between 33.5 and 34°C, which is about 1.5 to 2.5°C lower than that in the southern part. To assess the bleaching effects, coral genera counted during 60-minute dives were categorized into four groups including healthy, slightly bleached ( 50% bleached tissue) and fully bleached colonies. The anomalously high sea surface temperature resulted in massive coral bleaching (~84% coral colonies affected). Acropora spp. colonies, which are known as the most vulnerable corals to thermal stress, were less affected by the bleaching than massive corals, such as Porites, which are among the most thermo-tolerant corals. Turbid waters, suggested as coral refugia against global warming, did not protect corals in this study since most affected corals were found in the most turbid waters. The 2012 bleaching in the northern Persian Gulf was relatively strong from the viewpoint of coral bleaching severity. Long-term monitoring is needed to understand the actual consequences of the bleaching event on the coral reefs and communities.Los eventos de blanqueamiento de corales están aumentando en frecuencia y magnitud debido al aumento de la temperatura en los océanos. En este trabajo se describe un evento de blanqueamiento masivo observado en seis localidades del norte del Golfo Pérsico entre Agosto y Septiembre de 2012. Los datos de temperatura disponibles, medidas in situ y observaciones de satélites de la temperatura de la superficie del mar, sugieren que la temperatura umbral que desencadena el blanqueo de coral en el norte del Golfo Pérsico corresponde a una temperatura de entre 33,5-34°C que es una temperatura entre 1.5 a 2.5°C inferior a la observada en las zonas más meridionales del Golfo Persico (35-36°C). Para la evaluación de los efectos de blanqueo sobre las comunidades de coral, se realizaron transectos de 60 minutos entre 0 y 6 m de profundidad. Durante las inmersiones cada colonia de coral se identificó a nivel de género y su estado se asignó a una de las siguientes categorías: no afectada, ligeramente afectada ( 50% del tejido blanqueado) y colonias totalmente afectadas (100% del tejido blanqueado). El análisis de los datos de temperatura permitió identificar una anomalía térmica durante el periodo de blanqueamiento que afectó a un 84% de las colonias censadas. Contrariamente a otros eventos de blanqueamiento analizados, las colonias de Acropora spp., que se encuentran entre las especies más vulnerables al estrés térmico, fueron menos afectadas que las especies de corales masivos como Porites spp. que normalmente presentan una gran resistencia al estrés térmico. Igualmente a pesar que la turbidez de las aguas ha sido señalada como un factor protector en el contexto del calentamiento global, en nuestro estudio observamos que las zonas más afectadas por el blanqueamiento presentaban las tasas de turbidez más elevadas. En conclusión el evento de blanqueamiento de 2012 observado en el norte del Golfo Pérsico afectó severamente a las comunidades de coral. El seguimiento a largo plazo de las comunidades de coral se presenta como una necesidad para comprender las consecuencias de los eventos de blanqueamiento

Curriculum Reform and Iranian EFL Teachers' Professional Identity: A Marathon of Change!

Professional identity has been perpetually an underlying factor in teacher development. The maintenance of a strong professional identity is a key factor in teacher development which is ultimately a fundamental aspect in the prosperity or failure of any educational system. As a dynamic phenomenon, teachers’ professional identity can be influenced by a variety of factors and particularly any type of educational reform. The present study with an explanatory mixed method design was used to investigate transitions in Iranian EFL teachers’ professional identity in the context of Fundamental Reform Document of Education (2012). For the quantitative phase of the study, a researcher-made questionnaire developed based on the four components of professional identity namely, self-image, self-esteem, job motivation and task perception proposed by Kelchtermans (1993) was distributed among 98 Iranian EFL teachers. Considering the ongoing nature of the professional identity, the questionnaire was assigned to the teachers during the pre-reform and post – reform era. In the qualitative phase, in order to capture a comprehensive picture of the salient factors of teachers’ professional identity and their underlying reasons, a set of semi-structured interviews with 7 volunteer teachers were conducted. The findings revealed that the introduction of the curriculum reform made no change in teachers’ professional identity in terms of self-esteem and task perception, but it slightly affected teachers’ self-image and job motivation. The findings also revealed a potential transition path in Iranian EFL teachers’ professional identity development. Finally, some implications for policy-makers and material developers and suggestions for future researchers were discussed
