[Studying of knowledge and attitudes of non medical staffs of Mazandaran University of Medical Sciences about first aid and basic CPR in 2011]

According to the official statistics, cardiac arrest and accidents are included respectively as the first and second causes of death in Iran. Giving first aid to victims by trained people present at the scene causes less damage to the injured. This research was performed in order to study the current state of knowledge and attitudes of staffs of Mazandaran University of Medical Sciences about first aid and CPR. In this descriptive survey, all non-medical staffs [in headquarter and subordinate units] of Mazandaran University of Medical Sciences were studied in city of Sari in 2012. A total of 320 persons were selected and studied with stratified sampling using Cochran formula. By using a self-administered standardized questionnaire, data was collected in three parts: demographic information, knowledge and attitudes assessment. In order to evaluate validity and reliability, it was used of the opinion of public education experts of Red Crescent society and also university professors. However, the results of Cronbach's alpha coefficient [questions related to knowledge and attitudes r=0/83 and r=0/88 respectively] showed an acceptable internal consistency. The comparison of average score between the two groups indicated there were significant differences between the trained and untrained groups about knowledge of first aid [P<0/05, t=2/535]. However, significant differences were not observed between attitudes of two groups' average score towards first aid [0/05< P, t=0/618]. According to the results, Mazandaran University of Medical Sciences as one of the monitoring system and responsible organization for promoting health should improve the knowledge and awareness of its personnel. Since the staffs' information should keep up to date with appropriate retraining methods, appropriate educational programs should be launched for nonmedical staffs of the university. In this regard, one of the most important measures for officials is to pay more attention to promoting and training of first aid skills of the personnel

Thyroid function test in pre-term neonates during the first five weeks of life

Congenital hypothyroidism [CHT] is one of the most common congenital endocrinal disorders. The prevalence of CHT is estimated about 1 in 3,000 newborns. The prevalence, etiology and associated disorders of abnormal thyroid screening tests are reported in different ranges. In this study, we assessed the pre-term newborns for CHT and associated factors that influence thyroid function. One hundred newborns with the gestational age fewer than 35 weeks were investigated. Baseline serum thyroid stimulating hormone [TSH] and free thyroxin [FT4] levels were measured during the first 5 days of life and were repeated during the first 5 weeks. We analyzed the effects of demographic factors and the presence of respiratory distress syndrome on the alteration of thyroid function tests during the first 5 weeks of life. The mean gestational age [GA] at delivery was 32.35 +/- 1.97 [range 28 to 35] weeks. CHT was observed in 13[13%] preterm infants. GA was the only factor which affect the FT4 changes over the two weeks follow-up [P < 0.001, b: -2.783, Power: 70.2%] although the differences between baseline and follow-up amount of TSH were not significantly influenced by GA [P = 0.062, power: 46%]. However, the adjusted TSH and FT4 serum level changes during follow-up were significantly different between two groups [between CHT and normal, P = 0.006, 0.000, respectively]. It seems that thyroid function tests should be repeated in preterm infants, especially for patients with lower gestational age, to confirm the diagnosis of CHT. Also, CHT should be considered among the newborns that are affected by RDS.
