ABSTRACT
Bile duct adenoma (BDA) is a rare neoplasm of bile ducts with various clinical manifestations and imaging appearances. A few cases of BDA and their predisposing factors have been described. We report a 35-year-old woman with right upper quadrant pain who consumed oral contraceptive pills. Ultrasound study revealed three hypoechoic subcapsular liver masses; two of them were hypodense in computed tomography. Fine needle biopsy of the largest mass showed bile duct adenoma. Liver masses disappeared after discontinuing the pills over a 2-year follow-up. BDAs can manifest in imaging. Although previous studies have not reported tumor resolution over a follow-up period, we suggest paying more attention to predisposing factors in order to give an opportunity for tumor resolution by risk factor elimination.
ABSTRACT
AIM: To identify primary sclerosing cholangitis (PSC) predisposing factors in order to prevent inflammatory bowel disease (IBD) progression to PSC. BACKGROUND: IBD is commonly associated with PSC and there is no effective therapy for PSC except for liver transplantation. PATIENTS AND METHODS: This retrospective study was conducted on 447 IBD patients from IBD Clinics of Ghaem and Emam Reza Hospitals. Data were collected by interview and through a review of the patients' medical records. Patients were divided into two groups: those with IBD and PSC (IBD-PSC) and those without PSC. Variables were compared between two groups and those with statistically significant differences in IBD-PSC group were considered as predictive factors for the development of PSC. RESULTS: The frequency of PSC in IBDs was 4.3% and all were ulcerative colitis. The mean age of patients with PSC was 39.1±11.33 years. The male to female proportion in PSCs was 3.8:1 and in IBDs was 0.9:1. There were statistically significant associations between PSC and gender, IBD duration and UC extension, mucocutaneous involvement, oral contraceptive pills (OCP) consumption, history of surgery and history of PSC in the first- degree relatives. CONCLUSION: PSC frequency among IBD patients in North-East of Iran was 4.3%. It is recommended to limit OCP consumption in IBD patients. Identification and modification of probable predisposing risk factors, as well as early diagnosis of PSC are necessary.
ABSTRACT
BACKGROUND: The objective structured clinical examination (OSCE) has been introduced as an efficient method for the assessment of medical students. OBJECTIVES: The aim of the present study was to determine the satisfaction level of undergraduate medical students of internal medicine department with the OSCE. MATERIALS AND METHODS: This was a descriptive cross-sectional study, performed on all available undergraduate students at the end of their internal medicine training period in Mashhad University of Medical Sciences. The students responded to 15 multiple-choice questions with confirmed validity and reliability. RESULTS: The majority of the students (94.5%) had a positive attitude toward the OSCE and mentioned that the OSCE format was a more appropriate type of exam than other methods of testing; however, 79.1% thought that the OSCE format was stressful. In addition, the participants' sex had no effect on their level of satisfaction with the examination. Likewise, there was no significant correlation between their level of satisfaction and their age, marital status, or lack of previous experience with this type of exam. CONCLUSIONS: If the exam standards are met and a uniform dispersion of the scientific content is maintained, the OSCE method of assessment can be recommended as an efficient and applicable method for assessing medical students.
ABSTRACT
BACKGROUND: Gastroesophageal Reflux Disease (GERD) is a chronic and common disease, which is characterized by heartburn and regurgitation. In the last couple of decades, GERD has received much attention and studies have shown an increase in its prevalence. Although there have been a few studies on the prevalence of GERD in Iran, no study has yet been done in the northeastern part of the country. The aim of our study was to evaluate the prevalence of GERD and its risk factors in a population from Mashhad. OBJECTIVES: To evaluate the epidemiology of GERD based on a population study in Mashhad. PATIENTS AND METHODS: This was a cross sectional descriptive study conducted in 2010. In total, 2500 participants were selected based on cluster sampling. Modified and validated Mayo Clinic questionnaire for GERD was used for data collection. Overall, 1685 questionnaires were retrieved. Fifty-one participants were excluded because of pregnancies, history of abdominal surgery and being less than 18 years old. We analyzed data using the SPSS software version 16. Prevalence of GERD and significant risk factors (P value < 0.05) were determined. RESULTS: In total, 420 participants (25.7%) had GERD symptoms. Risk factors with significant effects consisted of smoking, consumption of non-steroidal anti-inflammatory drugs (NASIDs), overeating, chronic diseases, tea and coffee consumption and GERD in spouse. CONCLUSIONS: The prevalence of GERD among people living in Mashhad was above the average prevalence in other cities of Iran. However, risk factors seemed to be similar to those reported by other studies.
