Thrombocytosis in illicit drugs-exposed newborns.

Unlabelled: Thrombocytosis in infants exposed in-utero to illicit drugs has been associated to methadone exposure. Although is reported to present in the first two weeks, few studies address its duration and timing of resolution. This study evaluated the presence, duration, and complications of thrombocytosis in newborns exposed to illicit drugs.

Determination of papaverine and cocaine by use of a precipitation system coupled on-line to an atomic absorption spectrometer.

A continuous-precipitation flame-atomization atomic absorption spectrometric method for the determination of papaverine and cocaine hydrochlorides is proposed. The method is based on the precipitation of reineckates by injection of Reinecke's salt into a carrier containing the alkaloids and their subsequent retention on a stainless steel filter. In this way, papaverine and cocaine hydrochlorides can be determine over the ranges 5-85 and 50-850 micrograms ml-1 with a relative standard deviation of 1.

[Early intervention in infants with intrauterine growth retardation: its effects on neuropsychological development].

Forty-eight term infants in a tertiary center in Puerto Rico during 1985-86 were monitored prospectively since birth completing a neuropsychological evaluation using the Mental Developmental Index of Bayley Scales. All infants were free from perinatal complications and chronic diseases by clinical evaluation. 25 infants with intrauterine growth retardation (IUGR) and 23 adequate for gestational age (AGA) infants were evaluated.
