Phosgene, a highly reactive former warfare gas, is a deep lung irritant which produces adult respiratory distress syndrome (ARDS)-like symptoms following inhalation. Death caused by phosgene involves a latent, 6-24-h, fulminating non-cardiogenic pulmonary edema. The following dose-ranging study was designed to determine the efficacy of a non-steroidal anti-inflammatory drug, ibuprofen (IBU), and a methylxanthine, pentoxifylline (PTX). These drugs were tested singly and in combination to treat phosgene-induced acute lung injury in rats. Ibuprofen, in concentrations of 15-300 mg kg-1 (i.p.), was administered to rats 30 min before and 1 h after the start of whole-body exposure to phosgene (80 mg m-3 for 20 min). Pentoxifylline, 10-120 mg kg-1 (i.p.), was first administered 15 min prior to phosgene exposure and twice more at 45 and 105 min after the start of exposure. Five hours after phosgene inhalation, rats were euthanized, the lungs were removed and wet weight values were determined gravimetrically. Ibuprofen administered alone significantly decreased lung wet weight to body weight ratios compared with controls (Por = 0.01) whereas PTX, at all doses tested alone, did not. In addition, the decrease in lung wet weight to body weight ratio observed with IBU+PTX could be attributed entirely to the dose of IBU employed. This is the first study to show that pre- and post-treatment with IBU can significantly reduce lung edema in rats exposed to phosgene.

Physostigmine, as a pretreatment candidate for nerve agent poisoning, was examined for cardiopulmonary side effects. Cardiovascular and pulmonary parameters were monitored in unanesthetized domestic pigs which received pulmonary arterial infusion of 5 micrograms/kg/min physostigmine salicylate for 2 hr. A level of 74% inhibition of red blood cell (RBC) acetylcholinesterase (AChE) activity was attained in 45 min, and this level of carbamylation increased only slightly during the remaining infusion period. In addition to this large change in AChE activity, minor changes were observed in hematocrit, heart rate, body temperature, mean aortic pressure, pulmonary arterial wedge pressure, and pulmonary artery pressure. Typically, these parameters showed a trend toward elevated levels. Blood gases, pH, respiratory rate, tidal and minute volume, cardiac output, nonelastic resistance, and dynamic compliance were not significantly different from baseline values. The unanesthetized pig responds to physostigmine in a manner similar to that reported for other species and appears to be a suitable model for evaluating cardiopulmonary effects of cholinesterase inhibitors.

An investigation was conducted to develop a set of criteria that would allow the typical user to preselect a diamond-turning tool for the most critical optical finishing operations. A wide variety of tools used in this study had their edge quality evaluated by Nomarski and scanning electron microscopy methods, and the diamond crystal orientation and quality were determined by Laue x-ray methods. One of the tools was subjected to a long-term machining test to evaluate the tool wear process and to correlate the wear observed with changes in the scattering properties of the surface.

Diamond single-point tools of the very highest quality are required for precision machining of optical surfaces. However, a great variation in edge quality and tool life is observed in practice. The differences between poor and excellent tools are subtle and not easily detectable without verification by actual machining. A companion paper concerning the tribologic aspects of tool-edge quality and life discusses the possible mechanisms of tool degradation. This paper provides a discussion of practical methods for preselecting tools for high performance without resorting to machining use. Edge quality as observed by optical microscopy is not sufficient. Scanning electron microscopy and a recently developed two-stage replication process for the cutting edge and subsequent examination in transmission electron microscopy can yield the necessary resolution (<< 100 A). In addition to characterization by high resolution microscopy, tool crystallographic orientation and perfection are also crucial. X-ray diffraction characterization is described in detail.

To date, the tribology of the single-crystal diamond cutting edge and its effect on the diamond single-point machined optical surface is poorly understood. The factors that result in certain diamond tools having superior wear performance to others is equally uncertain. In addressing these issues, the present understanding of the tool-wear mechanisms involved in machining is reviewed, with particular emphasis on ultrahard tool materials. Current research at the Naval Weapons Center has attempted to extend this knowledge to the field of diamond-turned optics and identify the processes that degrade the performance of the tool.

The clasic concept that breathing is regulated only by chemoreceptor mechanisms in the arterial blood stream- the respiratory center, the carotid and aortic bodies-has been modified in two ways. It has been expanded by postulating another chemoreceptor which reacts to the composition of mixed venous blood. It has been qualified by questioning the assumption that the respiratory center has physiologically significant chemosensitivity. (The respiratory center is considered to be, on the contrary, primarily a computing mechanism that integrates information received from chemoreceptors responding to both arterial and mixed venous blood.) By postulating a chemoreceptor mechanism which reacts to the composition of mixed venous blood, a variety of ventilatory responses can be accounted for with a unified and semiquantitative concept based on the ventilatory response to exercise. For the quantitative description of exercise, data obtained from normal men at rest and during exercise have been used to develop several equations which describe the ventilatory response to exercise in terms of P(co)(2) and H(+) of arterial and mixed venous blood. The simplest of these equations, yet a useful one, is the following: V = 1.1 H(+)a + 2.3 Pv(co)(2) - 135 (5a) which states that the volume of breathing is determined by the algebraic summation of influences in arterial and mixed venous blood. Ventilatory responses, as measured in several experimental and clinical situations characterized by acid-base imbalance and associated hyperpnea, have been compared with the ventilation predicted by this equation and by the equation which quantifies Gray's multiple-factor theory. Equation 5a estimated the various ventilatory responses as closely as the multiple-factor theory equation did. Equation 5a was also able to predict ventilation during exercise. It is concluded, therefore, that the hyperpnea of muscular exercise may be a generally applicable expression of the ventilatory response to alterations of the composition of both arterial and mixed venous blood. When applied to the ventilatory responses of cross-perfused animals during exercise, the concept gives a satisfactory qualitative explanation of the various observations. Although there is strong indirect evidence that a chemoreceptor mechanism exists which reacts to the composition of mixed venous blood and whose activity can be quantified, the equations that have been developed are not definitive expressions of the stimuli which regulate breathing. That the equations apply as well as they do, in view of the known errors of fact in their development, is probably the best evidence yet adduced for the essential validity of the present concept.

- Abstract
Isopropanol, a known central nervous system depressant has been reported to cause toxicity via multiple routes including ingestion, inhalation and dermal exposure. We present a case of transplacental isopropanol exposure in a neonate. A woman reported polysubstance abuse in the 1 to 2 days before precipitously delivering a newborn infant. The neonate developed hypotension, hypotonia and seizure activity within the first few hours of life. Blood samples from the infant revealed toxic levels of isopropanol. Similar symptoms have been reported in infants with isopropanol toxicity from other routes of exposure.

- Abstract
Background: Inner-city children are frequently exposed to violence; however, there are few data regarding the psychological and academic correlates of such exposure in young children at school entry., Objectives: To document exposure to violence in inner-city children aged 7 years; assess their feelings of distress; and evaluate the relationships of exposure to violence with school performance, behavior, and self-esteem., Setting: A study center in an inner-city hospital., Participants: One hundred nineteen inner-city children evaluated at age 7 years; 119 caregivers (biological and foster)., Design: As part of a longitudinal study, children were administered the following by a masked examiner: Things I Have Seen and Heard (TISH) to assess exposure to violence; Levonn, a cartoon-based interview for assessing children's distress symptoms; and the Culture-Free Self-Esteem Inventory, Second Edition. School performance was assessed by school reports and child behavior by the Child Behavior Checklist (CBCL), the Parent Report Form, and the Teacher Report Form. Caregivers for children were administered the parent report version of the Checklist of Children's Distress Symptoms (CCDS-PRV) as well as the CBCL Parent Report Form., Main Outcome Measures: Exposure to violence (TISH); feelings of distress (Levonn); school performance; behavior (CBCL Parent Report Form and CBCL Teacher Report Form); and self-esteem (Culture-Free Self-Esteem Inventory)., Results: We found that these children were frequently exposed to violence. For example, 75% had heard gun shots, 60% had seen drug deals, 18% had seen a dead body outside, and 10% had seen a shooting or stabbing in the home (TISH). Many showed signs of depression and anxiety; eg, 61% worried some or a lot of the time that they might get killed or die and 19% sometimes wished they were dead (Levonn). Higher exposure to violence (TISH Total Violence score) was correlated with higher Levonn composite scores for depression and anxiety and with lower self-esteem (P< or =.04), and was also associated with lower grade point average and more days of school absence (P< or =.02). Caregiver assessment of child anxiety correlated poorly with child report of anxiety (P =.58)., Conclusions: Young inner-city children have a high exposure to violence by age 7 years; many show signs of distress that frequently are not recognized by caregivers. Further, higher exposure to violence in children correlates with poorer performance in school, symptoms of anxiety and depression, and lower self-esteem.

- Abstract
Children with in utero cocaine exposure may be at risk for adverse neurodevelopmental outcome. To evaluate such outcome in young children, we administered the Battelle Developmental Inventory (BDI) to a group of inner-city children with (COC) and without (CON) in utero cocaine exposure at ages 3 and 5 years. Sixty-five COC and 68 CON, similar at age of testing, were evaluated at both time points by examiners masked to child group status. Both groups scored poorly and worsened over time. Although Total BDI raw scores were lower in the COC group than in the CON group at 3 years, this difference was related to postnatal environmental factors, caregiver (p = .022), and home environment (p = .010), not to in utero cocaine exposure (p = .88). At 5 years, the Total BDI score was related to the home environment (p < .001) but not to the caregiver (p = .36) or in utero cocaine exposure (p = .83). We conclude that inner-city children are at risk for adverse developmental outcome regardless of in utero cocaine exposure.

- Abstract
To evaluate the problem-solving abilities of a cohort of inner-city cocaine-exposed children and controls, children were invited to play with the Goodman Lock Box, a large red and blue box with 10 compartments, each having a different lock and toy. Examiners, blinded to the children's group status, coded the children's activities during the 6.5-minute play period. Nineteen behaviors were collapsed into three outcomes: Aimless Actions, Competence, and Mental Organization. Groups' scores were compared with scores of the Goodman standardization sample of mixed socioeconomic status preschoolers. Seventy-three cocaine-exposed children and 82 controls were evaluated at age 3.5 years; of these, 58 cocaine-exposed and 63 controls were reevaluated at age 4.5 years. The groups' scores did not differ on any outcome at either time point (p > or = .22). However, both groups' Mental Organization scores were consistently lower than the Goodman group at each age (p < .01). This high-risk cohort may experience problems functioning in more complex environments such as the classroom.

- Abstract
Human milk oligosaccharides are known to play a role in protection against certain infectious diseases. Previous reports indicate that the content of human milk oligosaccharides varies widely among individuals at term but such information on preterm milk is lacking. After removal of the fat, protein and most of the lactose from non-pooled human milk samples, a total neutral oligosaccharide fraction was isolated by ion-exchange chromatography followed by gel filtration. A Dionex high-performance anion-exchange chromatography system equipped with a pulsed electrometric detector was then employed to measure the levels of ten neutral oligosaccharides in the individual milk samples. Twenty-three milk samples from thirteen mothers who delivered at a mean gestational age of 29.5 (SD 3.1) weeks were collected between days 0 and 33 of lactation, and compared with three samples of term milk from two mothers. The ranges of the total and individual levels of the ten neutral oligosaccharides in preterm milk were similar to those in term milk. Further, as previously described in term milk, preterm milk exhibited a quantitative individual variation. This variation was independent of the gestational age, day of lactation, and postconceptional age. In conclusion, levels of ten neutral oligosaccharides did not differ between preterm and term human milk.

- Abstract
Objective: To evaluate the effects of maternal magnesium sulfate treatment on newborn outcome., Methods: Subjects were newborn infants delivered at > or = 34 weeks of gestation whose mothers received a minimum of 12 hours of intravenous MgSO4 therapy before delivery. Control infants were the next born infants of similar gestational age. Outcome recorded at delivery included Apgar scores, whether resuscitation was required, and whether respiratory depression or decreased tone were noted by the physician in attendance. Pneumocardiograms on magnesium-exposed and control infants, obtained within 6 to 18 hours after delivery, were analyzed postdischarge by a single investigator who was blinded to group. The nursery course, feeding patterns, time to first stool, and time to first void were recorded. All patient care decisions, including admission to the neonatal intensive care unit (NICU) or term nursery, were independent of study protocol., Results: A total of 26 magnesium-exposed and 26 control infants were enrolled. The mean total dose of MgSO4 before delivery was 51.2+/-24 gm; the mean duration of therapy was 23.1+/-10 hours. The mean maternal serum magnesium level before delivery was 5.8+/-1.1 mg/dl. The infants' mean cord or initial serum magnesium level was 5.2+/-1.0 mg/dl, which correlated with the maternal magnesium level before delivery (r=0.81, p < 0.001). MgSO4-exposed infants had a higher incidence of hypotonia and lower median Apgar scores than control infants (p < 0.001). However, there was no association between adverse outcomes and maternal serum magnesium concentrations at delivery, duration of treatment, or dose of MgSO4. No difference in dose or length of maternal MgSO4 treatment was noted between infants admitted to term nursery and those admitted to NICU. Pneumocardiogram data were similar between MgSO4-exposed and control infants (all p > or = 0.16). There were no significant differences in number of episodes of feeding intolerance or in time to first stool or void between MgSO4-exposed and control infants (all p > or = 0.31)., Conclusion: Infants born to mothers treated with MgSO4 were more likely to be hypotonic and have lower Apgar scores at birth. Beyond the immediate postdelivery period, there were no additional complications in this cohort attributable to prenatal MgSO4 exposure. We suggest that pediatricians attend deliveries of magnesium-exposed infants.

- Abstract
Objective: To define characteristics that differentiate inner-city children with Average or above-Average Full Scale IQ scores (> or =90) from those with below-Average scores (<90)., Design: As part of a prospective study of children with and without in utero cocaine exposure tested at age 4 years on the Wechsler Preschool and Primary Scales of Intelligence-Revised, we found that, taken together, only 32 (21%) scored at or above 90 whereas 118 (79%) scored below 90. The groups (IQ> or =90 and IQ<90) were compared on prenatal, natal, and postnatal factors., Setting: A study center in an inner-city hospital., Participants: One hundred-fifty children of low socioeconomic status, 34 weeks' gestational age or older, and nonasphyxiated at birth, who had intelligence testing at age 4 years; 150 caregivers (biological and foster)., Main Outcome Measures: Association of Full Scale IQ with prenatal, natal, and postnatal characteristics (including caregiver-child interaction measured by the Parent Caregiver Involvement Scale [PCIS], and home environment measured by the Home Observation for Measurement of the Environment [HOME])., Results: The group of children with IQs at or above 90 (n = 32) did not differ from the group with IQs below 90 (n = 118) in prenatal or natal characteristics (all P> or =.18) or proportion in foster care, attendance at day care or Head Start, continued caregiver cocaine use, or parental IQ. Children with IQs at or above 90 had more developmentally appropriate interaction by caregivers (P=.043) and higher scores on 6 of 8 subscales and Total HOME (P< or =.05) than the group of children with IQs below 90., Conclusions: Two postnatal factors, home environment and caregiver-child interaction, were associated with Full Scale IQ scores at or above 90 whereas prenatal and natal factors were not. These potentially malleable postnatal factors can be targeted for change to improve cognitive outcome of inner-city children.

- Abstract
Objective: To determine if in utero cocaine exposure affects IQ scores in children at age 4 years., Design: A prospective, longitudinal evaluation by blinded examiners of the IQ scores of cocaine-exposed and control children of low socioeconomic status who have been observed since birth., Setting: A study center in an inner-city hospital., Participants: One hundred one children with in utero cocaine exposure and 118 control children, all of whom were 34 weeks' gestational age or older and nonasphyxiated at birth., Main Outcome Measure: Intelligence quotient scores on a standardized intelligence test, the Wechsler preschool and Primary Scale of Intelligence--Revised., Results: Seventy-one cocaine-exposed and 78 control children were administered the Wechsler Preschool and Primary Scale of Intelligence--Revised. Maternal, natal, and 30-month characteristics of the children tested did not differ from those not tested. Groups did not differ on mean Performance (83.2 vs 87.0), Verbal (79.0 vs 80.8), or Full Scale (79.0 vs 81.9) IQ scores (all P > or = .10 [values for cocaine-exposed children given first]). None of these 3 scores was associated with cocaine exposure in multivariate linear regressions. Although cocaine-exposed and control groups did not differ in outcome, 93% of cocaine-exposed and 96% of control children had Full Scale IQ scores below 100, the mean IQ score for the test., Conclusions: In an inner-city cohort, IQ scores did not differ between cocaine-exposed and control children. However, both groups performed poorly.

- Abstract
Objectives: The purpose of this study was to investigate (1) the presence of Clostridium difficile toxin in patients in the newborn intensive care unit and (2) the association of C. difficile toxin with gastrointestinal tract symptoms in this population., Study Design: A prospective, masked study was done in which twice-weekly stool specimens of subjects hospitalized in a newborn intensive care unit during a 4-month period were analyzed for C. difficile toxin A by enzyme immunoassay. Daily data collection included infant clinical status, stool frequency and character, presence of gastrointestinal tract symptoms, and actions taken for gastrointestinal tract symptoms. Infants hospitalized 5 or more days who had at least two stool assays comprised the study population. For data analysis, an infant with C. difficile toxin-positive status was defined as an infant with two or more toxin-positive stools., Results: Of 87 infants who met study criteria, 42 (48%) had toxin-negative and 45 (52%) toxin-positive results on at least one specimen. Of the infants with toxin-positive findings, 27 (31%) had two or more positive stool assays and comprised the comparison group. The infants with toxin-positive results were smaller, less mature, and had a longer hospital stay than infants with toxin-negative results (p < 0.001). Infants with toxin-positive findings had more days per infant with frequent (> 6) stools and abnormal stools (p < 0.001). The total number of symptom days was 8.2 +/- 5.7 in infants in the toxin-positive group versus 2.2 +/- 2.2 in those in the toxin-negative group (p < 0.001). The mean number of times stools were sent for evaluation and culture was greater in infants with toxin-positive findings (p < or = 0.012) whereas there was no difference in the number of times oral feedings were withheld from infants or infants had abdominal films obtained (p > or = 0.18)., Conclusions: Infants hospitalized in our newborn intensive care unit frequently had stools positive for C. difficile toxin A. When compared with infants with toxin-negative findings, infants with colonization had an increased number of days with gastrointestinal tract symptoms.

- Abstract
A cohort of children of low socioeconomic status, 76 with in utero cocaine exposure and 81 control subjects, was assessed for early language development at 2 1/2 years of age by a masked examiner using the Preschool Language Scale. There were no differences between groups in expressive, receptive, or total language score (all p > or = 0.57). Physicians caring for cocaine-exposed children with early language delay should not automatically ascribe the delay to cocaine exposure but should initiate a standard evaluation for language delay.

- Abstract
Play behavior was compared between toddlers with in utero cocaine exposure and controls of similar low socioeconomic status enrolled at birth in a prospective, masked study. At 18 and 24 months, 83 cocaine-exposed and 93 control toddlers were videotaped playing on their own for 15 minutes. An observer who was off-site and unaware of project purpose or drug exposure status of toddlers recorded the most cognitively complex play activity per 15-second interval. In a total of 315 play sessions, the groups did not differ in middle and highest level of play achieved at either 18 or 24 months (p > or = .27). After controlling for confounders, the proportions of play behavior in each of six play categories were similar in the two groups at both 18 and 24 months (p > or = .42). We conclude that in utero cocaine exposure was not associated with differences in play behavior in this cohort of cocaine-exposed and control toddlers.

- Abstract
Cocaine use by pregnant women has increased dramatically in recent years. To assess the effect of maternal cocaine use on infant outcome, we enrolled 224 women (105 cocaine users, 119 control subjects) and their infants (all of 34 weeks or more gestational age and nonasphyxiated) in a prospective, blinded study. Results showed that infants exposed to cocaine were more likely to be admitted to the newborn intensive care unit, be treated for congenital syphilis, have a greater length of stay, and be discharged to a person other than the mother (all p < 0.01). Birth weight and head circumference, adjusted for gestational age, were smaller in the infants exposed to cocaine than in control infants (p < 0.001). After statistically controlling for cigarette use and other confounders, however, the odds of infants exposed to cocaine and control infants having birth weight and head circumferences less than the 25th percentile for gestational age did not differ (both p > 0.80). Infants of cocaine-using mothers and control subjects had a similar incidence of abnormal cranial and renal ultrasonographic findings and abnormal pneumocardiograms (all p > or = 0.32). We conclude that in this cohort of nonasphyxiated infants of 34 weeks or more gestational age, infants exposed to cocaine had more medical and social problems than control infants but did not differ statistically in the incidence of severe growth retardation, abnormal cranial or renal ultrasonographic findings, or abnormal pneumocardiograms. We suggest that natal interventions for the nonasphyxiated term and near-term infant exposed to cocaine should include a careful history and physical examination, follow-up plans, and social service involvement.

- Abstract
This prospective, blinded study evaluates the effect of in utero cocaine exposure on outcome of nonasphyxiated, term and near-term children born to women of low socioeconomic status. Two hundred nineteen children (101 cocaine-exposed and 118 control) with extensive natal evaluations are evaluated at 6-month intervals. We report here growth, performance on the Bayley Scales of Infant Development (BSID) through 30 months of age, and tone and reflexes at 6 and 12 months. To date, subjects have had 816 follow-up visits, with subject retention greater than or equal to 73%. Cocaine-exposed children showed statistically lower mean weights and smaller mean head circumferences than control children over the 30-month follow-up period (p < or = .011). The percentage of children with abnormal tone and reflexes, however, was similar in the two groups at 6 and 12 months (p > or = .34). Mean BSID Mental Development Index (MDI) and Psychomotor Development Index scores did not differ between the two groups (p > or = .16), although both groups' scores decreased over time (p < .001). Of concern, both cocaine-exposed and control groups had lower mean MDI scores than those published for a group of children of higher socioeconomic status. We conclude that, in our cohort of children, low socioeconomic or minority status may have had a substantial influence on BSID scores whereas in utero drug exposure did not.

- Abstract
Neonatal intensive care units are essential for the successful care of very immature and sick infants. The technology of NICUs has contributed significantly to the reduction of neonatal mortality and improvement of neonatal outcome. While the outcome for high-risk neonates has vastly improved over the past three decades, a number of infants sustain injuries and complications that result in long-term disabilities. It is now clear that some of the long-term problems of high-risk infants are a result of the environment and care practices and are not attributable to the original disease or condition that necessitated intensive care. There is accumulating evidence that environmental factors and care practices can interact with disease processes in ways that can increase morbidity, and possibly mortality. In addition to developmental and behavioral problems, there is growing evidence of effects on visual function and perhaps other sensory systems. Many of the environmental and care factors may cause delay in recovery and increase NICU time or unnecessary discomfort, yet not produce long-term disabilities or problems, as currently assessed. Many of the potential behavioral and developmental problems, as well as many of the potential problems with visual, auditory, and other modes of sensory discrimination, are not included in the usual follow-up assessments. The absence of data or the limitations of existing studies are not a cause for comfort or the assumption that the environment and care practices are safe or not harmful.(ABSTRACT TRUNCATED AT 250 WORDS)

- Abstract
Pulmonary hypoplasia is lethal in its most severe form; in less severe cases the clinical course is protracted, usually resulting in chronic lung disease. A case of unexpected survival of an infant with clinical and radiologic evidence of pulmonary hypoplasia, in whom dexamethasone was administered, is presented. Possible mechanisms of dexamethasone's influence on outcome are discussed.

- Abstract
To determine if there is a specific postnatal (PNA) or postconceptional age (PCA) at which ventilated preterm infants respond to beta-agonists, we evaluated 15 infants with a mean gestational age of 26.5 +/- 1.5 weeks and mean birth weight of 0.89 +/- 0.23 kg who required mechanical ventilation at 10 days of age. Weekly pulmonary function testing (PFT) was performed before and 1 h after administration of albuterol. Taking the group as a whole, as well as individual babies, regression analysis showed no relationship between positive response and either PNA or PCA. Evaluation of individual infants, however, showed that some consistently responded to beta-agonists whereas others did not. We recommend individual PFT to identify those infants who will benefit from use of beta-agonists.

- Abstract
Cardiac septal hypertrophy occurs after in utero ritodrine exposure. To assess the effect of septal hypertrophy on cardiac function we obtained M-mode echocardiograms on day 1 of life in 41 infants exposed to ritodrine and 22 control infants matched for gestational age. Mean duration of ritodrine exposure was 16.2 +/- 13.2 days (range 1 to 49 days). Disproportionate septal hypertrophy (DSH) was defined as an interventricular septal thickness/posterior wall thickness ratio (ST/PW) of greater than 1.3. Infants exposed to ritodrine in utero had DSH and increased right systolic time intervals compared with control values (P less than 0.05). A subgroup, those infants exposed for 2 weeks or longer, had not only DSH but also an absolute increase in septal thickness compared with control infants and infants exposed to ritodrine for less than 2 weeks. ST/PW correlated well with the duration of ritodrine exposure (r = 0.96); the longer the exposure the thicker the septum. Although all echocardiographic changes lasted for less than 3 months, we have no information regarding the effect on the fetus of maternal ritodrine exposure for longer than 7 weeks. Until such information is available, cardiac evaluation is recommended in neonates exposed to ritodrine in utero for longer than 7 weeks.

- Abstract
The Perinatal Continuing Education Program consists of a nine-month intervention with community hospital nurses, physicians, and support personnel. Components include a hospital self-inventory of resources, coordination by community hospital staff, a skills workshop, and self-instructional books. This article outlines a follow-up strategy to the basic program and describes changes in community hospital knowledge and care practices that occur between programs. The follow-up program presented includes a modified coordinators' workshop, identification of updated self-instructional materials for careful study by past participants, and a self-survey of "recommended routines" intended to facilitate change in hospital policies. Otherwise, except for the deletion of the resources inventory, the follow-up program is similar to the basic program. Testing of participants and detailed review of 1435 hospital charts at sequential time periods revealed a decline in mean knowledge scores between programs, higher scores by new participants before follow-up when compared to pre-basic program, a plateau of patient care quality between programs, and a further improvement in patient care quality after the follow-up program. We conclude that a follow-up program is best accepted after three years but that timing is not critical. Evaluation measures suggest that new knowledge and care practices become institutionalized as a result of this program and that altered care practices are not simply a result of improved performance by individuals.
