Abstract
The purpose of this study was to determine the outcome of high-dose therapy with autologous hematopoietic stem cell support (autotransplants) in men with breast cancer. We studied 13 men receiving autotransplants for breast cancer and reported to the Autologous Blood and Marrow Transplant Registry (ABMTR) by 10 centers. Six men had stage 2 breast cancer, four had stage 3, and three had metastatic breast cancer. Of twelve tumors tested, all were estrogen receptor positive. Median age at transplant was 50 years. The most common conditioning regimen was cyclophosphamide, thiotepa and carboplatin (n = 5); the remaining eight men received other alkylator-based regimens. Three men received bone marrow, eight received blood stem cells, and two received both for hematopoietic support. All patients had hematopoietic recovery. There were no unexpected regimen-related toxicities. Of 10 men receiving autotransplants as adjuvant therapy, three relapsed 3, 5 and 50 months post-transplant and died 16, 19 and 67 months post-transplant. Seven of 10 are disease-free with median follow-up of 23 months (range 6-50 months). Of three men treated for metastatic breast cancer, one had progressive disease and two recurrent disease at 6, 7 and 16 months post-transplant. In conclusion, results of autotransplants for male breast cancer appear similar to those reported for women receiving autotransplants for breast cancer.

Abstract
OBJECTIVE To determine whether exposure to tobacco smoke in late pregnancy can be reliably estimated by measuring carbon monoxide (CO) in the mother and newborn breath. STUDY DESIGN Sixty-eight mothers and their healthy term singleton newborns, delivered at a university-affiliated community hospital in Jerusalem, were enrolled. End-tidal CO (corrected for inhaled air [ETCOc] was measured with a portable automated bedside CO analyzer. ETCOc, cotinine, and carboxyhemoglobin (COHb) levels were compared in 17 smoking, 31 passively exposed, and 20 nonsmoking mothers and their offspring. RESULTS The mean +/- SD ETCOc was significantly higher in women who smoked than in passively exposed and nonsmoking mothers (8.42 +/- 5.65 vs 1.95 +/- 0.98 vs 1.33 +/- 0.84 ppm. p < 0.0001, respectively). Newborns whose mothers smoked had higher ETCOc levels than those of infants of passively exposed and nonsmoking mothers (10.0 +/- 7.7 vs 2.51 +/- 1.4 vs 1.74 +/- 0.98 ppm, p < 0.0001, respectively). The number of cigarettes smoked by the mother was significantly correlated with maternal ETCOc (r = 0.755, p < 0.00001), and neonatal ETCOc (r = 0.805, p < 0.00001). Maternal ETCOc was highly correlated with neonatal ETCOc (r = 0.857, p < 0.00001), cotinine (r = 0.645, p < 0.00001), and COHb (r = 0.9, p < 0.00001) levels. Birth weight was significantly associated with neonatal ETCOc (p < 0.006) and maternal ETCOc (p < 0.007). CONCLUSION ETCOc levels in the newborn are well correlated with maternal smoking. Measurements of newborn ETCOc may be used as a noninvasive means to estimate exposure to maternal tobacco smoke immediately before delivery. These measurements will be useful for patient education and research.

Abstract
High intensity light-emitting diodes (LEDs) are being studied as possible light sources for the phototherapy of hyperbilirubinemic neonates. These power-efficient, low heat-producing light sources have the potential to deliver high intensity light of narrow wavelength band in the blue-green portion of the visible light spectrum, which overlaps the absorption spectrum of bilirubin (BR). We compared the efficacy between single LEDs of different color and then constructed a prototype phototherapy device using 300 blue LEDs. The efficacy of this device was compared with that of conventional phototherapy devices by measuring the in vitro photodegradation of BR in human serum albumin. When blue, blue-green, green, and white LEDs were compared, the blue light was the most effective in degrading BR by 28% of dark control, followed by blue-green (18% of control), and then white light (14% of control). Green light was the least effective (11% of control). The prototype device with three focused arrays, each with 100 blue LEDs, generated greater irradiance (> 200 microW.cm-2.nm-1) than any of the conventional devices tested. It also supported the greatest rate of BR photodegradation. We conclude that light from LEDs should be considered a more effective treatment for hyperbilirubinemia than light from presently used phototherapy devices. Furthermore, the unique characteristics of this light source may make it especially suitable for use in safe and lightweight home phototherapy devices.

Abstract
CONTEXT Editorial management of articles on health economics may benefit from guidelines for peer review and revision. OBJECTIVE To assess whether publication (in August 1996) of the BMJ guidelines on peer review of economics submissions made any difference to editorial and peer review processes, quality of submitted manuscripts, and quality of published manuscripts. DESIGN AND SETTING Before-after study conducted in the editorial offices of BMJ and The Lancet of the effect of the BMJ guidelines on review and revision of economics submissions, defined as those making explicit comments about resource allocation and/or costs of interventions. MAIN OUTCOME MEASURES Editorial fate and changes in the quality of submissions. RESULTS A total of 2982 manuscripts were submitted to the 2 journals during the before periods, 105 (3.5%) of which were economics submissions. Of these, 27 (24.3%) were full economics evaluations, and 78 (75.7%) were other economics submissions. Overall acceptance rate was 11.6% (12/105). During the after period 2077 manuscripts were submitted to the 2 journals, 87 (4.2%) of which were economics submissions. Eighteen (20.7%) were full economics evaluations, and 69 (79.3%) were other economics submissions. Overall acceptance rate was 6.9% (6/87). Although a number of manuscripts could not be traced to determine whether they were economics submissions, there appeared to be little difference between the 2 journals in numbers or editorial fate of the manuscripts. There was no change in the quality of submitted manuscripts, but BMJ editors found the guidelines and checklists useful and sent fewer economics submissions for external peer review in the after phase. CONCLUSIONS Publication of the guidelines helped the BMJ editors improve the efficiency of the editorial process but had no impact on the quality of economics evaluations submitted or published.

Abstract
The use of pressure-sensitive adhesives (PSAs) for skin-contact applications is discussed. The requirements of such adhesives in various applications are examined in detail. Commercially available classes of PSAs used for skin-contact applications are the acrylics, the polyisobutylenes, and the silicones. The main application examined in this review is transdermal drug delivery. The roles played by the PSA in two types of transdermal designs are described. Correlations between in vivo and ex vivo measurements of adhesion are discussed. Also, the reported human studies of various commercially available transdermals are examined critically, with a view to assessing the relative performance capabilities of each type of transdermal design. Finally, a comprehensive listing of currently commercialized transdermals is given.

Abstract
It has been suggested that the high rates of prematurity, low birth weight, perinatal morbidity and mortality in in-vitro fertilization (IVF) infants are due to the increased frequency of multiple gestations in this population. The aim of our study was to test this hypothesis by comparing the outcome of IVF twins with that of twins born after spontaneously conceived pregnancies. The perinatal outcome of 40 IVF twins was compared with that of 80 control twins, matched for maternal age, parity and ethnic origin. IVF twins had a higher rate of prematurity (P = 0.03), their mean birth weight was significantly lower (P < 0.01) and the frequency of very low birth weight infants was much higher (P < 0.003). There was no neonatal mortality in the control group, whereas four IVF twins died (P < 0.01). Neonatal morbidity was significantly greater in IVF twins (P < 0.05). Oxygen therapy and mechanical ventilation were administered more frequently to IVF twins (P < 0.007 and P < 0.05). We conclude that twins conceived by IVF are at a significantly higher risk for prematurity and associated neonatal morbidity and mortality than spontaneously conceived twins.

Abstract
OBJECTIVE To determine the predictive value of macrosomia for overweight later in adult life in infants of diabetic mothers. DESIGN Data from the computerized records of the Jerusalem Perinatal Study were matched to measurements made at age 17 obtained from the military draft medical examination records. PARTICIPANTS 10,891 infants born in Jerusalem between November 1974 and February 1976. MAIN OUTCOME MEASURES Macrosomia based on 90th percentile birth weight for gestational age and overweight defined as the 90th percentile for body mass index at age 17. RESULTS Diabetes was diagnosed in 87 (0.8%) of the mothers. Thirty-one (35.6%) of the infants of the diabetic mothers were macrosomic compared to 1012 (9.4%) of the siblings of nondiabetic mothers (p < 0.001). At 17 years of age 10.3% vs. 9.4% of the siblings of diabetic vs. nondiabetic mothers were overweight (p > 0.05). The rate of adolescent overweight in macrosomic vs. nonmacrosomic subjects was 12.3% vs. 9.7% (p < 0.01) in siblings of nondiabetic mothers, and 16.1% vs. 7.1% (p > 0.05) for diabetic mothers. The sensitivity and specificity, in diabetic mothers, of macrosomia for overweight at age 17 was 44.4% and 66.7%, respectively. The positive and negative predictive value of macrosomia for overweight at age 17 was 16.1% and 92.9%, respectively. CONCLUSIONS The risk of adolescent overweight was significantly increased among macrosomic infants, although this trend did not reach statistical significance in the smaller group of infants born to diabetic mothers. Macrosomia among infants of diabetic mothers had little predictive value for overweight in late adolescence.

Abstract
OBJECTIVE To assess the effect of size at birth, maternal nutrition, and body mass index on blood pressure in late adolescence. DESIGN Population based analysis of birth weight corrected for gestational age, mother's weight before pregnancy and weight gain in pregnancy, obtained from the Jerusalem perinatal study, and blood pressure and body mass index at age 17, available from military draft records. SETTING Jerusalem, Israel. SUBJECTS 10,883 subjects (6684 men and 4199 women) born in Jerusalem during 1974-6 and subsequently drafted to the army. MAIN OUTCOME MEASURES Systolic and diastolic blood pressures measured at age 17 and their correlation with birth weight, size at birth, mother's body mass index and weight gain during pregnancy, and height and weight at age 17. RESULTS Systolic and diastolic blood pressures were significantly and positively correlated with body weight, height, body mass index at age 17, and with mother's body weight and body mass index before pregnancy, but not with birth weight or mother's weight gain in pregnancy. CONCLUSION Variables reflecting poor intrauterine nutrition, including low maternal body mass index before pregnancy, poor maternal weight gain in pregnancy, and being born small for gestational age, were not associated with a higher blood pressure in late adolescence.

Abstract
UNLABELLED Prenatal exposure to ritodrine may be associated with a lower incidence of RDS in premature infants, independent of its effect on prolongation of pregnancy. OBJECTIVE The purpose of this study was to assess the neonatal respiratory outcome of premature infants according to whether their mothers were treated prenatally with ritodrine. STUDY DESIGN A retrospective review was done of all 247 infants born at 34 weeks of gestation or less in our hospital during a 6-year period. A multivariate logistic regression was used to adjust for possible confounding variables. RESULTS Among the ritodrine-exposed infants respiratory distress syndrome developed in 9.5% (4/42) compared with 28% (57/205) in the unexposed group (p < 0.012; adjusted odds ratio 4.88, 95% confidence interval 1.27 to 18.70). The gestational age and birth weight were similar in the two groups. The incidence of transient tachypnea of the newborn and other neonatal complications was not statistically different between the two groups. CONCLUSION Ritodrine was associated with a significantly lower incidence of respiratory distress syndrome in premature infants, independent of the effect of ritodrine on prolongation of pregnancy.

Abstract
Combined duodenal and jejunal atresia is extremely uncommon. The familial occurrence of congenital duodenal and small bowel atresia is even more unusual. To the authors' knowledge, this is the first report of two siblings with simultaneous duodenal and jejunal atresia who underwent successful surgical repair. The report may support the genetic origin of some forms of high intestinal atresia.

Abstract
In 1993 the North London Blood Transfusion Centre received its first report of Yersinia enterocolitica transmission from a unit of red cells supplied to a local hospital. The recipient was a 23-year-old male who was neutropenic following a third cycle of chemotherapy for treatment of acute myeloblastic leukaemia (FAB type M6) and received a 34-day-old red cell unit. During transfusion the patient developed septicaemia and endotoxin-mediated shock. The transfusion was stopped immediately and broad spectrum antibiotics administered immediately on suspicion of bacteraemia from the transfused unit. This prompt action undoubtedly prevented a fatal outcome. Y. enterocolitica was isolated from the blood bag. Antibody was also detected in the bag and in a sample taken from the donor 39 days post-donation. Antibody to serotype 03 was identified, the commonest serotype reported in transfusion-transmitted Y. enterocolitica. The donor reported no gastrointestinal upset or illness prior to donation. This transfusion reaction might not have occurred had the red cells been transfused earlier in their storage period, but would not have been prevented by the exclusion of donors with a history of gastrointestinal illness as the donor was asymptomatic. Nor would it have been prevented by inspecting the blood for a change in colour, as no such change was observed. Y. enterocolitica is a significant problem in transfusion medicine and transmission is generally associated with a high mortality rate. Hospitals should be urged to investigate bacteriologically all appropriate transfusion reactions so that the true extent of the problem in the United Kingdom can be assessed.

Abstract
Delayed childbearing has become common and has raised the awareness of the possible risks for the mother and the newborn infant. The increased maternal and neonatal risks have been attributed largely to the lack of proper prenatal care. The aim of this study was to assess whether advanced maternal age is a significant risk factor in mothers who receive good prenatal care. We matched 161 cases 1:1 according to the following criteria: maternal and paternal ethnic origin, chronic diseases, marital status, and smoking during pregnancy. Our results show that the older women had babies with a significantly higher incidence of low birth weight (< 2500 gm, p = 0.001), prematurity (< 37 weeks, p = 0.02), intrauterine growth retardation (p = 0.001), abruptio placentae (p = 0.002), and cesarean section (p < 0.001). The average hospital stay for the babies of the older mothers was longer than that for babies of the younger mothers (8.4 vs 6.1 days, p = 0.003), and the incidence of hospitalization for more than 3 days in the neonatal intensive care unit was increased (10.3% vs 2.2%). Logistic regression did not support maternal age of 35 years and older as being the single significant risk factor for adverse neonatal and maternal outcome. We conclude that maternal age older than 35 years entails a higher risk for the mother and her newborn infant, even when good prenatal care is taken.

Abstract
End-tidal carbon monoxide was measured in 108 newborn infants who had been screened for glucose-6-phosphate dehydrogenase (G6PD) deficiency. The mean +/- SD end-tidal carbon monoxide did not differ significantly between the G6PD-deficient and the normal neonates, 2.1 +/- 0.6 microliters/L and 2.0 +/- 0.5 microliters/L, respectively, within 12 hours of birth and 1.9 +/- 1.4 microliters/L and 1.5 +/- 0.7 microliters/L, respectively, at 48 to 72 hours after birth. On the basis of these measurements, hemolysis is not a sufficient explanation for jaundice in G6PD-deficient newborn infants in the transitional period.

Abstract
Severe neonatal hyperbilirubinemia can occur without apparent reason in term healthy breast-fed infants and some develop kernicterus. The aim of our study was to assess the incidence of severe hyperbilirubinemia in term healthy newborns discharged from the hospital. From January 1 through December 31, 1994, 6705 infants were delivered at Bikur-Cholim and Misgav-Ladach Community Hospitals. All 1448 newborns discharged with a serum bilirubin level > 10.0 mg/dL were instructed to return to the hospital within 3 days for follow-up, as well as bilirubin determination. Twenty-one newborns with a bilirubin level > 18.0 mg/dL were identified and readmitted at mean +/- standard deviation (SD) 5.5 +/- 1.8 (range, 5 to 10 days of life). This represents 1.7% of the 1220 infants who returned for follow-up examination. Mean +/- SD serum bilirubin levels at readmission were 19.6 +/- 2.5 mg/dL. All but one of the infants were breast-fed. No cases of ABO incompatibility were found and two newborns were glucose-6-phosphate dehydrogenase (G6PD)-deficient. Sepsis work-up and direct Coomb's tests were negative in all cases. None had hemolysis or were found to have any cause for hyperbilirubinemia other than breast-feeding. Phototherapy was provided in all but two cases, and an exchange transfusion was performed in one case. Three additional infants, with bilirubin levels < 10 mg/dL at discharge, were readmitted due to hyperbilirubinemia. One was diagnosed with neonatal hepatitis. We conclude that, based on our study population, 0.36% of term infants may subsequently develop severe neonatal hyperbilirubinemia in the first postnatal week.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Twenty-four children born preterm with very low birthweight (VLBW) in 1985 at Bikur Holim Hospital were followed until age 6 years. Their neurological status and developmental and cognitive abilities were examined at 1, 2 and 6 years of age respectively and were compared with a control group at age 6 years. Of the 24 VLBW children, 4 had major disabilities. Of those without major disabilities, mean total IQ (WPPSI) at six years was 101.5 +/- 11.3, not significantly different from their mean Mental Development Index (Bayley) at age 2 years which was 96.1 +/- 19.6, or from the mean total IQ of a control group of 6-year-old children which was 109.8 +/- 14.7. However, the mean verbal IQ of the VLBW children (95.3 +/- 11.7) was significantly lower than that of the control group (106.2 +/- 14.3) (P = 0.02). Minor neurological deficit was found in seven of the VLBW children and in only one of the controls (P = 0.05). These findings point to possible future learning difficulties and should alert both pediatricians and educationalists to the importance of long-term follow-up of VLBW children in order to identify and address their specific educational needs.

Abstract
OBJECTIVE To assess the cognitive and academic performance of adolescents who were born small for gestational age (SGA) at term. METHODS A 17-year historical prospective study was done by matching neonatal data of 1758 infants to the results of the medical and intelligence assessment performed at age 17 years at the army draft board medical examination in Israel. The results of children born SGA (weight at term birth below the third percentile) were compared to those of children who were born appropriate for gestational age (AGA). RESULTS After adjustment by a multiple linear regression analysis, the mean (+/- standard error of the mean) intelligence test scores were 103.1 +/- 2.9 versus 105.8 +/- 1.5 (P = 0.3) for the males and 100.3 +/- 2.5 versus 104.7 +/- 1.6 (P < .03) for the females. Males born SGA at term were found to have lower educational achievements (having less than 12 years of schooling or attending a vocational school) compared with the AGA group. The odds ratio for this finding after adjustment by a logistic regression analysis was 2.40 (95% confidence interval 1.07-5.39; P < .03). Intranatal events were not found to have an effect on the measured neurodevelopmental outcome. CONCLUSION Infants born SGA at term have an increased risk for lower cognitive performance and schooling achievements than those born AGA; this result seems to be unrelated to their intranatal course.

Abstract
To assess the maternal and neonatal risk associated with high-order cesarean sections, a case-control study was carried out in two university affiliated maternity wards. The outcome of 154 pregnancies of women undergoing cesarean section for the 4th time or more was compared with 148 women sectioned for the 2nd or 3rd time and 132 women of similar age and parity after spontaneous birth. The main outcome measures were maternal operative and postoperative morbidity and neonatal prematurity and its complications, Apgar scores, and the need for intensive care. Women undergoing multiple (> or = 4) cesarean sections had significantly more intra-abdominal adhesions (P < 0.0001) than women sectioned for the 2nd or 3rd time. However, the time interval from incision to delivery and the total duration of operation were similar. The postoperative course was not adversely affected by multiple cesarean sections. A high incidence (16.2%) of preterm cesarean deliveries was noted in the study group. This was due to non-elective repeat cesarean delivery rather than to poor timing of scheduled cesarean sections. The significantly increased (P < 0.05) need for neonatal intensive care was explained by the higher occurrence of prematurity. Low Apgar scores (< or = 7) at 1 and 5 min were significantly (P < 0.01) related to multiple cesarean sections, even after controlling for the effect of gestational age. We conclude that multiple cesarean sections pose little risk for the mother, but may be associated with increased neonatal risk, attributed mainly to preterm non-elective cesarean sections.

Abstract
Phototherapy for neonatal hyperbilirubinemia was introduced to our medical center in March 1971. To assess the influence of phototherapy on subsequent cognitive outcome, we compared the intelligence test scores at 17 years of age of subjects born 4 months before and 10 months after the introduction of phototherapy. The intelligence quotient score (mean +/- SE) at 17 years for 84 subjects with severe neonatal hyperbilirubinemia was 108 +/- 2 for those treated by phototherapy and 107 +/- 2 for controls matched for gestational age and birth weight. The confounding effect on intelligence quotient scores of perinatal factors (bilirubin concentrations, gestational age, birth weight, Apgar score) and demographic characteristics (ethnic origin, socioeconomic status, paternal education) was taken into account in a multiple logistic regression analysis by using a General Linear Models procedure. Phototherapy was found to have no independent effect on intelligence quotient scores after adjustment for the effect of confounding factors. We conclude that for full-term newborn infants with neonatal hyperbilirubinemia, phototherapy had neither a beneficial nor an adverse effect on intellectual ability in late adolescence.

Abstract
A survey of MD candidates in one teaching hospital and two postgraduate institutes was undertaken to determine their initial training needs, and their preferred methods of learning about the conduct of research. Fifty-six respondents (53% response rate) replied to a piloted questionnaire. Their replies indicated a need for intensive initial research training, offered at local level by the supervisor. The supervisor's subsequent role throughout the research period should be to provide ongoing specific critical help and support. It is concluded that teaching materials and designed teaching sessions might be provided for supervisors to assist them in their new role.

Abstract
The association between birthweight and body height attainment at 17 years of age was investigated by studying a sample of 30,083 subjects born in Jerusalem between 1964 and 1971. Birthweights obtained from the computerized records of the Jerusalem Perinatal Study were matched with demographic and medical examination results available from the military draft boards. Linear regression models for standing height by birthweight were fitted for the data in order to adjust for the possible confounding effect of ethnic origin, socioeconomic status (as determined by parental education level), birth order and maternal age. Separate models were constructed for each sex. A significant (P < 0.0001) linear increase in standing height by birthweight of 3.33 cm/1,000 g was observed for the males (mean +/- SE height 174.5 +/- 0.1 cm) and 2.85 cm/1,000 g for the females (mean +/- SE height 163.5 +/- 0.1 cm). This positive linear association between body height at 17 years of age and birthweight was also demonstrated after stratification according to various categories of social class and ethnic origin. Adult body height was thus found to be strongly related to birthweight in both sexes, regardless of ethnic and socioeconomic influences.

Abstract
A prospective 2-year neurodevelopmental follow-up was carried out on 69 very low birthweight (VLBW) infants (< 1501 g), born in the years 1985-87. The aim of the study was to determine whether there was a long-term advantage to cesarean section in these infants. The incidence of major disability and cognitive ability at 2 years of age were assessed, comparing modes of delivery. Cesarean section was performed in 38 out of 69 (55.1%) of the infants. Major disability was diagnosed in 11/69 (15.9%) of the children, of whom 7/38 (18.4%) were delivered by cesarean section, compared with 4/31 (12.9%) delivered vaginally. The difference, accounting for presentation and multiple birth was not statistically significant. Cognitive ability at 2 years of age was tested using the Mental Development Index (MDI) of the Bayley Scales, and was compared, according to mode of delivery, in 55 of 58 infants without major disability. There was no statistically significant difference between mean +/- S.E. in the MDI of 28 infants delivered by cesarean section (99.7 +/- 7.3) and that of 27 infants delivered vaginally (95.6 +/- 4). In summary, at 2 years of age, no clinically relevant benefit was found for VLBW infants who had been delivered by cesarean section.
