Abstract
To determine the therapeutic dose of Mg according to BMI, serum level of calcium, creatinin and albumin a cross sectional study were carried on 150 cases of preeclampsia (100 mild, 50 sever type) in Valei-Asr Hospital through the years 1378-79. All of eligible patients had given a single dose of 4 gr Mg, sulfate intravenously, then had continued with 20 gr/lit, 28 drop/min through IV infusion. Mild and sever preeclampsia cases were similar about the mean serum level of calcium and Mg. Before beginning of treatment, but were significantly different about the mean of serum level of creatinin and albumin (P=0.0001). In univariat analysis there was significant direct correlation between serum level of Mg 6 hours after beginning of treatment with serum level of creatinine and albumin, and significant association with BMI (P<0.05). So the serum level of Mg in end of treatment, (P<0.05) in multivariate regression analysis, the serum level of Mg in 6 hours after and end of treatment was correlated positively with serum level of creatinine and albumin and negatively with BMI. Serum level of Mg 6 hours after=-0.2+0.8 (Alb. Level) +2.99 (creat level) –0.22 (BMI). Serum level of Mg in end of treatment=-0.2+0.8 (Alb. Level) +3.3 (creat level) –0.24 (BMI).

Abstract
Primitive Peripheral Malignant Neuroectodermal Tumor is a malignant neoplasm of neural origin with high mortality which occurs mostly in children and adolescents. The most common site of involvements are chest wall and paraspinal regions. Head and neck involvement is rare. The diagnosis is based upon histopathologic and immuno-histochemical studies. Treatment is combination of surgery, radiotherapy and chemotherapy. In this article we present a rather rare case of PNET which occurred in the neck area of a child.

Abstract
Background: Patients with severe mental illnesses are more prone to experience sexual health problems. Herein, we developed a "Safe Sex Knowledge and Behavior Questionnaire for Patients with Severe Mental Illnesses"(SSKBQ-SMI).
Methods: The present study was conducted in the form of methodological research in 4 stages. In the first stage, items of the questionnaire were selected and the item pool was formed by using similar studies and experts' opinions. During the next steps, the psychometric properties of the questionnaire were assessed using content validity, face validity, reliability and construct validity. The content validity was tested using the Content Validity Index and Content Validity Ratio. The charts of content validity were given to 13 specialists expert in sexual health including psychiatrists, clinical psychologists, gynecologists, urologists, and infectious disease specialists. The reliability was tested by using the test-retest method in 70 patients with two-week intervals. The construct validity was tested using exploratory factor analysis in 265 patients. The internal consistency was calculated by using Cronbach's alpha index.

Results: After determining the content and face validity, a tool was obtained with 16 True/False items in the knowledge section (with one score for each correct answer and the total score range from 0 to 16) and 16 five-point Likert scale items in the behavior section (with each question score range from 0 to 3 and the total behavior score range from 0 to 48, the lower score defined safer behavior). The correlation coefficient of the scale scores in the test-retest method was calculated to be 0.880 (P<0.001) and 0.951 (P<0.001) in the sections of knowledge and behavior, respectively. The Cronbach's alpha coefficient was 0.809 for the section of knowledge, 0.756 for the section of behavior, and 0.782 for the whole questionnaire. Exploratory factor analysis confirmed the existence of 4 factors in the knowledge section and 3 factors in the behavior section.
Conclusion: The present 32-item questionnaire was designed based on experts' opinions and important statements of patients about sexual health, simple scoring, good reliability and validity, is a suitable tool for assessing the safe sex knowledge and behavior in patients with severe mental illnesses.
