Birth weight and other fetal growth measures (head circumference buy generic wellbutrin 300mg online depression effects, birth length) are consistently decreased among infants born to heroin addicts compared to drug-free controls (Fricker and Segal, 1978; Kandall et al. Miscarriages, perinatal death, and a variety of other perinatal complications were increased in frequency among heroin-exposed children (Fricker and Segal, 1978; Kandall et al. Fetal exposure to heroin is confounded by the gen- erally poor health status of heroin-using mothers. Postnatal growth of children exposed to heroin prenatally seems normal compared to controls and reference data (Little et al. However, head circumference was smaller than that of children not exposed to heroin prenatally in several studies (Chasnoff et al. As noted for all substances of abuse dis- cussed in this chapter, heroin crosses the placenta freely. If the mother is addicted to heroin, her infant is also addicted because the drug rapidly enters fetal circulation. Accordingly, neonatal withdrawal symptoms (tremors, irritability, jitteriness, diarrhea, seizures, poor feeding, high-pitched, shrill cry, irregular sleep patterns, sneezing, respira- tory distress, fever, vomiting) occur among 40–80 percent of infants born to heroin- using gravidas (Alroomi et al. Withdrawal symptoms may appear shortly after birth or take from 6 to 10 days to develop, depending upon the time needed for the infant to metabolize heroin at birth. These symptoms can be of prolonged duration, usually per- sisting for less than 3 weeks. Opiate abuse during pregnancy 323 Ultimately, the postnatal environment of infants exposed prenatally to heroin seems to primarily determine developmental status (Ornoy et al. This seems to be true for most substances of abuse, except alcohol and perhaps cocaine. Methadone Methadone is a synthetic opiate narcotic structurally similar to propoxyphene. The prin- cipal medical use of methadone is as a maintenance therapy for heroin addiction, but it is used illegally as a substitute for heroin. Published studies reported include only preg- nant women on regimented-dose maintenance therapy who took methadone of known pharmacological purity. Congenital anomalies were not increased in frequency compared to the background rate among infants born to heroin-addicted women treated with methadone during pregnancy (Fundaro et al. However, withdrawal symptoms occurred frequently (up to 80 percent) and birth weights were significantly lower (2600 g) among methadone-exposed infants (n = 278) (Connaughton et al. Neonatal complications occur at a high rate, and include asphyxia neonatorum, transient tachypnea, aspiration pneumonia, congenital syphilis, jaundice, meconium staining, and neonatal death. Adverse maternal effects include prolonged rupture of membranes, breech presentation, abruptio placentae, preeclampsia, and postpartum hemorrhage (Naeye et al. Of the 17 infants, 14 were born to mothers who were enrolled in a methadone treatment program, but who continued to use other drugs as well. Review of effects of methadone maintenance during pregnancy on neonatal out- come showed two consistent findings across studies: withdrawal symptoms (70–90 per- cent) and lowered gestational age and birth weight of infants in the drug-exposed group compared to a control group (Behnke and Eyler, 1993). Developmental outcomes of heroin- and/or methadone-exposed children Several researchers have been following, assessing, and reporting on the progress of chil- dren born to heroin- and methadone-using mothers. Overall, heroin- and methadone- exposed children obtained lower scores than comparison groups in the domains of motor coordination, attention and focus, activity level and behavior, emotional distur- bances, and behavioral problems (aggression, anxiety, and rejection) (Behnke and Eyler, 1993; Davis and Templer, 1988; de Cubas and Field, 1993; Deren, 1986; Kaltenbach and Finnegan, 1984; Wilson et al. Summary of opiates during pregnancy Chronic use/abuse of opiates during pregnancy does not significantly increase the risk of congenital anomalies. Adverse pregnancy outcomes are increased in frequency: abruptio 324 Substance abuse during pregnancy placentae, neonatal withdrawal, preterm birth, and fetal growth retardation. Some dif- ferences were found in cognitive abilities, motor development and behavior between opiate-exposed children and nondrug-exposed children, but the postnatal environment with a drug-abusing mother must be considered because it is an important factor. Maternal personality traits, degrees of life stress, the quality of the mother–child rela- tionship, and assessment of the environment must be considered. In Dallas, it was estimated that 1 per- cent of women used inhalants during pregnancy, including toluene, spray paint, gasoline, freon, and other substances (Madry et al. Women who use inhalants during preg- nancy are primarily Hispanic or American Indian, with an age range of 20–29 years (Goodwin, 1988; Wilkins-Haug and Gabow, 1991). In Dallas, the majority of women using inhalants during pregnancy are young, 15–20 years of age, and usually Hispanic.

Lawrence wellbutrin 300 mg line depression test for loved ones, the brother of Ernest, made the frst clinical therapeutic application of an artif- cial radionuclide when he used phosphorus-32 to treat leukemia. Also Joseph Gilbert Hamilton and Robert Spencer Stone administered sodium-24 to a leukemia patient. Furthermore, this year Emilio Segre and Seaborg discovered Tc-99m the metastable (excited) Tc-99 isotope. The metastable isotope has a half-life of 6 hours and emit a g-photon with energy 140 keV. Tc–99m is an important isotope and is used in approximately 85 percent Emilio Segrè of diagnostic imaging procedures in nuclear medicine. The development of nuclear accelerators – in particular the cyclotron – made it possible to enter the feld of nuclear medicine. Two scientists are of utmost importance for the construction of the frst accelerators; Rolf Widerøe and Ernest Lawrence. The development of the cyclotron and the beginning of nuclear medicine is closely connect- ed to California and the Berkeley University. It all started when the oldest of the Lawrence brothers (Ernest) came to Berkeley in 1929. In a linear accelerator charged particles are accelerated in tubes forming a straight line. Lawrence arranged this by letting the particles go in larger and larger circles within a box – kept in place by a magnetic feld. Ernest Lawrence Rolf Widerøe (1901 – 1958) (1902 – 1996) Ernest Lawrence is of Norwegian heritage Rolf Widerøe is Norwegian, born in Oslo. He was He was engaged in the construction of an the father of the frst cyclotrons constructed accelerator, and published these ideas al- in Berkeley. His name is The Radiation Laboratory in Berkeley are connected to important acellerators for radi- named after him. He was an exciting public science center with excit- behind the frst high energy radiation source ing hands-on experiences for learners of all in Norway – the betatron from 1953 at The ages. The above picture is a model of a cyclotron – placed near the entrance of “Lawrence Hall of Science” in Berkeley. The Berkeley University developed a number of accelerators and become the place where new isotopes were produced. The leading scientist in the production of new isotopes and elements was Glenn Seaborg. Glenn Seaborg (1912 – 1999) Glenn Seaborg was a Swedish American (his mother was from Sweden). Seaborg was the prin- cipal or co-discoverer of ten elements: plutonium, americium, curium, berkelium, californium, ein- steinium, fermium, mendelevium, nobelium and element 106, which was named seaborgium in his honor while he was still living. He also developed more than 100 atomic isotopes, like I-131 and Tc- 99m which are important isotopes for medicine. Seaborg was avarded the Nobel prize for Chem- istry in 1951 together with another Berkeley sci- entist Edwin McMillan. He used for the frst time a radioactive isotope in the treatment of a human disease (leukemia). John Lawrence became known as the father of nuclear medicine and Donner laboratory is considered the birthplace of this feld. Hal Anger (also a Donner man) invented in John Lawrence Hal Anger 1958 the gamma-camera – also called Anger (1904 – 1991) (1920 – 2005) camera. This is also called “Anger camera” and consisted of a large fat scintilla- tion crystal and a number of photomultipliers. They used I-131 labeled insulin to measure the reaction between an antigen and antibody. David Kuhl 193 Some of the isotopes used in nuclear medicine The use of radioactive isotopes in research and medicine can be divided in three groups. Isotopes used as tracers A radioactive isotope attached to an important molecule can tell where it is.

Diazepam 2 buy cheap wellbutrin 300mg on line mood disorders johns hopkins, or 3/d ´ 2 d 45 mL 6f,12m 388 Subjects were tested on mental and then psychomotor performance starting at +1 h. Ethanol enhanced the effects on two of nine mental tests; no effect on psychomotor tests. Tofisopam 100, or ´ g/kg 12m 112 Enhanced impairment on coordination, reaction, flicker fusion, maddox wing and attention tests. When ethanol was given 3 h after alprazolam, only minimal effects were found (116). When ethanol was given only 45 min after alprazolam, however, it had additive effects on most of the end points measured (110). Similarly, combining ethanol with diazepam at the same time led to enhanced impairment of reaction time (112), whereas giving the ethanol 3 h after diazepam did not (116). Ethanol, therefore, does appear to enhance the impairing effects of benzodiaze- pines in an additive fashion. In the one study that measured driving skills, diazepam and ethanol were taken together and the stimulated driving of professional drivers was 1. The combined use of ethanol and diazepam resulted in increased numbers of collisions and driving off the road instances (117). In general, acute use of ethanol is associated with the inhibition of drug metabolism; chronic use induces metabolism (118,119). Therefore, examination of the effect of ethanol on benzodiaz- epine pharmacokinetics should differentiate between studies on acute exposure in non- alcoholics (Table 17) and studies in alcoholics (Table 18). Note that experiments were designed to test ethanol as a solvent for addition of substrates. Thus is the case for brotizolam (120), chlordiazepoxide (121), clobazam (111), and triazolam (122). With some benzodiazepines, however, ethanol did not have any effect on their pharmacokinetics; these include alprazolam (116), clotiazepam (123), flu- nitrazepam (124), and prazepam (125; Table 17). For the latter studies, either the 3-h interval between alprazolam and ethanol administration, or the ability of non-P450- dependent pathways to metabolize flunitrazepam may explain the negative findings. Such is not the case, however, for clotiazepam and prazepam, which require P450 for either hydroxylation or N-dealkylation reactions. For these two benzodiazepines the effect was not significant, but could be considered suggestive of impaired elimination. Diazepam interactions with ethanol were the subject of numerous studies that showed varying results. An inhibition of clearance was reported in some studies (126–128), whereas only a prolongation of the Cmax was found in some studies (121,129–131). In general, the former studies administered ethanol 30–60 min prior to diazepam, whereas the latter administered the two drugs at the same time. The results from these clinical studies indicate that acute ethanol, taken either with or shortly before, may interfere with the elimination of many, but not all benzo- diazepines. Although this would appear to arise from the inhibition of P450-depen- dent metabolism of the benzodiazepines, some inconsistencies exist. A single study was found on the in vitro inhibition of different forms of human liver P450s (132). Cytochrome P450 3A4, which is associated with the metabolism of many benzodiaz- epines, was fairly resistant to the inhibitory effects of ethanol for the marker substrate studied (Fig. Drug Interactions with Benzodiazepines 37 site(s), however, it has become apparent that some substrates may show different re- sponses to inhibitors. The study of benzodiazepine pharmacokinetics in chronic alcoholics entering treat- ment programs has been used to support the theory that chronic ethanol induces the metabolism of benzodiazepines (56). Either a comparison within the subjects at 1–2 d after initiation of treatment vs 6–7 d later, or comparison of the subjects to control subjects. With the former design, adminis- tration of oral, intramuscular or intravenous chlordiazepoxide had longer t1/2s of higher steady-state concentrations at the beginning of the study (133,134). It was suggested that these results arose from an initial inhibition of chlordiazepoxide from residual ethanol in the first sesssion with unmasking of an induced state in the later session (56). This is supported by studies on diazepam where abstinent alcoholics were compared to non- alcoholic controls (Table 18).
