Experience of early diagnosing of Bland-White-Garland syndrome in paediatric practice

Myocardial infarction and acute coronary syndrome in children is referred to as a rare congenital anomaly up to the present date. However, despite the rarity of this syndrome, practicing pediatricians, cardiologists should be cautious about the disease in order to avoid the fatal consequences of untimely diagnosis. The article describes the main causes, pathogenesis, clinical picture, treatment tactics and disease prognosis – according to the literature of Russian and foreign authors, and presents a clinical discussion of the case of early detection of the Bland-White-Garland syndrome during the planned outpatient examination of the child

The mass spectra of 10,10-dimethyl-9,10-dihydro-10-sila-2-azaanthracenes with heterocyclic substituents at C9

The major pathways for the fragmentation of dihydrosilaazaanthracenes, containing an azetidine substituent, spiro-β-lactam ring, or spirotetrahydrofuryl residue at C9 upon electron impact are related to the presence of these rings. The azetidine ring may be eliminated as a radical or by splitting "in half" to give [M-Me]+ ions. Splitting of the spiro-β-lactam ring "in half" leads to the two strongest ions M+. The loss of the tetrahydrofuryl ring leads to ions of 9-methylene- and 9-oxosilaazaanthracenes. The dlmethylsilyl group loses a methyl radical at various stages of the decomposition. © 1990 Plenum Publishing Corporation
