Hybrid Ameloblastoma in the Anterior Man-dible  [PDF]
Mandana Pourian, Mersad Mehranahad, Pooneh Dehghan
Advances in Computed Tomography (ACT) , 2015, DOI: 10.4236/act.2015.43006
Abstract: Ameloblastoma—a benign epithelial odontogenic tumor-histologically occurs in different patterns, the most common of which are plexiform and follicular. “Hybrid” ameloblastoma is a variant in which areas of follicular or plexiform pattern (generally called convention alameloblastoma) coexist with areas of pronounced stromal desmoplasia (desmoplastic ameloblastoma). They most often occur in the mandibular ramus. We present a case of “hybrid” lesion—desmoplastic and conventional ameloblastoma—in the anterior mandible, focusing on its’ imaging features.
Impact of Reflective Writing and Labatorials on Student Understanding of Force and Motion in Introductory Physics  [PDF]
Calvin S. Kalman, Mark Lattery, Mandana Sobhanzadeh
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.94041
Abstract: In this paper, we examine a way to deal with alternative student conceptions about force and motion in a university level introductory physics course.? The course combines Reflective Writing,an activity that engages students in textual material metacognitively, and Labatorials,an in-class active learning intervention. Semi-structured interviews and student writing provide evidence of conceptual change.
Prediction of Mortality Circumstances in the Pediatric Intensive Care Unit

Research Journal of Biological Sciences , 2012,
Abstract: We aimed to describe mode of death and the circumstances surrounding dying a pediatric intensive care unit. A retrospective descriptive study all patients (<15 years) dying in the PICU of tertiary care hospital from April 2004 to Jun 2006 (n = 74). Information regarding sex, age, Length of Stay (LOS), primary and admission diagnosis and the way of death was determined. Deaths were classified in 5 groups: Do not resuscitate (DNR), Withdrawal or Limitation of Therapy (W/LT), failed cardiopulmonary resuscitation (Failed CPR), brain death (BD) and terminal organ failure (TOF). Among 1075 admission, 6.8% patients died. Afton admitted during evening (43%). 40.8% died in the first two days. Failed CPR was the most common mode of death (66.2%), BD was found in 14.9%, TOF in 12.2%, W/LT in 2.7% and DNR in 4.1%. We observed that failed CPR is the most common mod of death and active withdrawal is still not widely practiced in our PICU because pediatricians in developing countries have to consider socio cultural and religious factors when making such decisions.
Congenital Tuberculosis Proven by Liver and Lymph Node Biopsy
Naiyereh Najati,Mandana Rafeey
Research Journal of Biological Sciences , 2012,
Abstract: Congenital tuberculosis is defined as tuberculosis occurring in infants as a result of infection acquired from their mothers. Congenital tuberculosis maynot be rare and it is necessary to look into this condition more seriously. Tsanscutaneous liver biopsy may help to confirm it`s prenatal origin and explain causes of the multi organ involvement. We report a case of congenital tuberculosis diagnosed by liver biopsy in infant with FTT and hepatosplenomegally. A 5 month old male infant developed FTT, fatty diarreha and abdominal distension. He had cough, wheezing and weight loss too. On the physical examination there was hepatosplenomegally, axillary and inguinal lymph node enlargement. All of investigations were negative except percutaneous liver and lymph node biopsy that revealed many acid fast bacilli.
Endoscopic Findings and Helicobacter pylori in Children on Long-Term Hemodialysis

Pakistan Journal of Biological Sciences , 2008,
Abstract: The aim of this study is to evaluate the prevalence of GI symptoms, endoscopic abnormalities, histologic gastritis and Helicobacter pylori infection in children with End Stage Renal Disease (ESRD) undergoing maintenance hemodialysis. Upper endoscopy and gastric biopsy were performed in 31 consecutive ESRD children from 2002-2007, before renal transplantation. H. pylori status was determined by urease test and histology. The mean age of patients was 11 ±3.3 years (4-16 year). The mean duration of dialysis was 12.4 ±11 months (1.5-54 months). Seventeen patients (54.8%) were symptomatic. Twenty patients (64.5%) had endoscopic abnormalities. Antral erythema, esophagitis, antral nodularity and diffuse gastritis were common endoscopic findings. Endoscopic abnormalities were more common in symptomatic patients than asymptomatic patients (p<0.05). Twenty patients (64.5%) were H. pylori positive. There was no statistical correlation between age, sex, serum creatinine level, presence of any symptoms and endoscopic abnormalities with H. pylori positivity. The mean duration of dialysis in H. pylori negative patients was significantly longer in comparison with H. pylori positive patients. High prevalence of eodoscopic abnormalities and H. pylori infection in both symptomatic and asymptomatic patients emphasize the necessity of upper GI evaluation in ESRD children before renal transplantation.

Perceived barriers in accessing food among recent Latin American immigrants in Toronto
Vahabi Mandana,Damba Cynthia
International Journal for Equity in Health , 2013, DOI: 10.1186/1475-9276-12-1
Abstract: Objective In Canada, recent immigrant households experience more food insecurity than the general population, but limited information is available about the personal, cultural, and social factors that contribute to this vulnerability. This study focused on recent Latin American (LA) immigrants to explore their perceived barriers in acquiring safe, nutritious, and culturally-appropriate food. Design A cross-sectional mixed-method design was applied to collect information from a convenience sample of 70 adult Spanish/Portuguese speakers who had arrived in Toronto within the last five years. Face-to-face interviews were conducted with primary household caregivers to obtain responses about barriers to acquiring food for their households; data were analyzed using a thematic analysis technique. Results Four main categories of barriers were identified: limited financial resources; language difficulty; cultural food preferences; and poor knowledge of available community-based food resources and services. Inadequate income was the main impediment in accessing adequate food, and was related to affordability of food items, accessibility of food outlets and transportation cost, and limited time for grocery shopping due to work conditions. Language barriers affected participants’ ability to obtain well-paid employment and their awareness about and access to available community-based food resources. Cultural barriers were related to food preferences and limited access to culturally-appropriate foods and resources. Conclusion The main barrier to food security among our sample of LA newcomers to Toronto is limited financial resources, highlighting the need for policies and strategies that could improve their financial power to purchase sufficient, nutritious, and culturally-acceptable food. Linguistic barriers and limited information among newcomers suggest the need to provide linguistically- and culturally-appropriate information related to community-based food programs and resources, as well as accessible subsidized English language programs, in the community and at workplaces. Participatory community-based food programs can augment, in a socially acceptable manner, food resources and reduce the social stigma attached to food charity. Finally, it is crucial to monitor and evaluate existing social and community-based services for their accessibility, cultural appropriateness and diversity, and effectiveness.
