Purpose: Cranial magnetic resonance imaging (MRI) is recommended to identify intracranial lesions in girls with central precocious puberty (CPP). Yet, the use of routine MRI scans in girls with CPP is still debatable, as pathological findings in girls 6 years of age or older with CPP are limited. Therefore, we aimed to identify the prevalence of brain lessons in CPP patients stratified by age group (0–2, 2–6, and 6–8 years).Methods: This retrospective cross-sectional study recruited 257 girls diagnosed with CPP for 6 years (2010–2016). MRI was used to detect brain abnormalities. Levels of luteinizing hormone, follicle-stimulating hormone, and sex hormones in blood samples were measured.Results: Most girls had no brain lesions (82.9%, n=213), and of the minor proportion of girls with CPP that exhibited brain lesions (17.1%, n=44), 32 girls had organic CPP. Pathological findings were detected in 33.3% (2 of 6) of girls aged 0–2 years, 15.6% (5 of 32) of girls aged 2–6 years, and 3.6% (8 of 219) of girls aged 6–8 years. Hypothalamic hamartoma and tumors in the pituitary stalk were the most common pathological findings. The likelihood of brain lesions decreased with age. Girls with organic CPP were more likely to be younger (6.1±2.4 vs. 7.3±1.3 years, p<0.01) than girls with idiopathic CPP.Conclusion: Older girls appeared to have a lower prevalence of organic CPP. Clinicians should cautiously use cranial MRI for girls aged 6–8 years with CPP.

Cucurbitane-type triterpene glycosides from the fruits of Momordica charantia
Nhiem, Nguyen Xuan,Kiem, Phan Van,Minh, Chau Van,Ban, Ninh Khac,Cuong, Nguyen Xuan,Ha, Le Minh,Tai, Bui Huu,Quang, Tran Hong,Tung, Nguyen Huu,Kim, Young Ho John Wiley Sons, Ltd. 2010 Magnetic resonance in chemistry Vol.48 No.5
<P>The chemical study of Momordica charantia fruits led to the isolation of three new cucurbitane triterpene glycosides, momordicosides U, V, and W (1–3). The structures of these compounds were determined to be (19R, 23R)-5β, 19-epoxy-19-methoxycucurbita-6,24-diene-3β, 23-diol 3-O-β-D-allopyranoside (1), (23R)-5β, 19-epoxycucurbita-6,24-diene-3β, 23-diol 3-O-β-D-allopyranoside (2), and (19R)-5β, 19-epoxy-19,25-dihydroxycucurbita-6,23(E)-diene-3β-ol 3-O-β-D-glucopyranoside (3), by chemical and spectroscopic methods.
