The utility of spectral Doppler evaluation of acute appendicitis.

Purpose: The use of spectral Doppler, peak systolic velocity (PSV), and resistive index (RI) imaging criteria to improve the accuracy of acute appendicitis diagnosis is hypothesized.

Methods: Graded compression ultrasound was performed for suspected patients. The spectral Doppler evaluation was conducted while observing the appendix.

Evaluation of weekly intramuscular methotrexate in the treatment of low risk gestational trophoblastic neoplasia.

Background: The gestational trophoblastic neoplasms (GTNs) are rare and potentially life-threatening malignancies.

Aims: The aim of this study was to determine the rate of response to weekly intramuscular (IM) methotrexate (MTX) in patients with low-risk GTN (LR-GTN).

Settings And Design: The study was designed cross-sectional and prospectively.

The effect of smoking by family members and friends on the incidence of smoking among high school students.

Objective: Smoking is the most important preventable cause of death. According to the global youth tobacco survey (GYTS) presented by WHO, 25% of smokers smoked their first cigarette before the age of 10; hence, it is of great importance to investigate the effect of smoking of family members and friends on smoking incidence of adolescents.

Materials And Methods: This analytic cross-sectional study was conducted on the basis of GYTS questionnaire.
