Question: We conducted this study to analyze the values of the key cephalometric angular measurements of the mandible using 3-dimensional (3D) computed tomography scans.', 'In the 106 enrolled patients, a 3D cephalometric analysis was performed to measure the angular variables of the mandible. These values were compared between the two sides and between the two sexes.', 'The frontal measurements revealed that the mandibular body curve angle was larger on the left (Lt) side (right [Rt], 141.247.54; Lt, 142.686.94; P=0.002) and the gonial angle was larger on the right side (Rt, 134.378.44; Lt, 131.547.14; P<0.001). The sagittal measurements showed that the gonial angle was larger on the right side (Rt, 134.378.44; Lt, 131.547.14; P>0.05). Further, the transverse measurements revealed that the mandibular body curve angle was larger on the right side (Rt, 140.287.05; Lt, 137.566.23; P<0.001).

Question: Studies have reported effects of prenatal marijuana exposure (PME) on cognitive and behavioral outcomes. An earlier publication from this study found that PME predicted early onset of marijuana use and frequency of marijuana use at age 14. No study has reported the effects of PME on marijuana use in young adulthood. This is a developmental period when substance use peaks, and by which, initiation of substance use has largely occurred.', 'Subjects were from a longitudinal cohort. Women were interviewed initially in their fourth prenatal month and women and their offspring were followed through 22 years. Significant covariates of offspring marijuana use at 22 years were identified and controlled for using ordinal logistic regression.', 'PME predicted marijuana use in the offspring at 22 years after controlling for significant covariates. Prenatal alcohol exposure, offspring race, gender, and age were also significant predictors, but family history of substance abuse or disorder, and sociodemographic and psychological characteristics of the mother and offspring were not. This association was not moderated by gender or race.

Question: There are few data concerning prognostic markers of acute myocarditis. The purpose of this study was to assess the prognostic value of initial measurements of creatine kinase (CK), cardiac troponin I (cTnI) and myoglobin as regards late recovery of the left ventricular ejection fraction on follow-up.', 'A total of 22 patients (53+/-15 years old, 11 female) with acute myocarditis were followed up in a prospective observational study. Of these, 11 (50%) showed a history of acute infection prior to hospitalisation and seven (32%) had pericardial effusion. The median ejection fraction during the acute phase was 47+/-17%; after a mean follow-up of 119+/-163 days it improved to 60+/-9% (P<0.001). Considering maximal CK-rise values of 641+/-961 U/l (P=0.38), cTnI-rise values of 3.7+/-8.6 microg/l (P=0.16) and myoglobin values of 7.4+/-12 nmol/l (P=0.69), there was no correlation between initial cardiac enzyme levels and the initial and late left ventricular ejection fraction.
