Abstract
Congenital tracheal anomalies occur in 1:10,000 births and can be associated with congenital cardiac disease. This patient presented with right mainstem atresia, right bronchoesophageal fistula without esophageal atresia (H-type esophageal lung), and left pulmonary arterial (PA) sling. Taking this into consideration, surgical management included right pneumonectomy and placement of expandable prosthesis into the thoracic cavity to buttress the mediastinum and prevent tracheal deviation-induced kinking of the PA sling, which provided pulmonary blood flow to the remaining functional lung. To our knowledge, this is the first reported case of esophageal lung in conjunction with a PA sling, as well as the first documented use of an expandable prosthesis to prevent acute postpneumonectomy syndrome. This case can provide clinicians with increased clinical knowledge for treatment of this rare and potentially lethal combination of congenital anomalies.

Abstract
The aim of this work was to disclose risk factors associated with birth defects which were heterogeneously distributed in the different geographic regions sampled by the Latin American Collaborative Study of Congenital Malformations (ECLAMC). The material included 2,159,065 hospital births, delivered in the 1967-1989 period in 24 geographic regions of Latin America. Birth defect types with 50 case-control pairs or more were analyzed. A risk factor was defined as that available variable with differential geographic rates, correlated with those of a given birth defect type. Identified factors were tested by case-control multivariate logistic regression to confirm their role in the occurrence of the defect. Altitude and maternal acute illness during first trimester of pregnancy, named influenza, were risk factors for microtia. Prenatal drug exposure, mainly sex hormones, were connected with the occurrence of hypospadias in low frequency areas, while Native ancestry was a "protective" factor in the same regions. Acute (influenza), and chronic (epilepsy and syphilis) maternal illness during first trimester of pregnancy and gravidity higher than four were risk factors for cleft lip. The independence of these variables from maternal age suggested that low maternal socioeconomic level could explain the high birth defect order and, perhaps, syphilis in mothers. Postaxial polydactyly was associated with parental consanguinity, as well as Afro-American ancestry, suggesting genetic heterogeneity.

Abstract
From a multiracial population of 1,035,384 births monitored by the California Birth Defects Monitoring Program (CBDMP) from 1983 to 1988, we ascertained 34 cases of esophageal atresia (EA), 204 cases of tracheoesophageal fistula (TEF) with an EA (TEF/EA), and 54 cases of TEF without EA. The total prevalence rate was 2.82 per 10,000 live births and stillbirths and showed no secular trend nor marked seasonal variation. Rates of multiple birth were high for each defect (TEF 3.7%, TEF/EA 4.9%, EA 8.8%; population 1.1%). Non-Hispanic whites were overrepresented for TEF and TEF/EA, but not for EA. Excluding trisomies, mean maternal age was above the population mean (26.8 years) for TEF (27.9 years) and TEF/EA (28.0 years), but not for EA (26.2 years). The proportion of trisomies was significantly higher for EA (23.5%) than for TEF (9.3%; P < 0.02) or for TEF/EA (7.4%; P < 0.003). We subdivided each defect into five mutually exclusive types: isolated, multiple, syndromic, chromosomal, and trisomic. Male-to-female (M/F) ratios varied considerably between types, both within and between defects. The highest M/F ratios within each defect were for the multiple type (TEF 2.29, TEF/EA 1.44, EA 1.33; population 1.05), and the lowest for trisomies (TEF 0.25; TEF/EA 0.25, and EA 0.60). All types except trisomies were significantly associated with a single umbilical artery. We found an association of EA and TEF/EA with dextrocardia (3.1% of cases), and confirmed the association of primary hydrocephalus with TEF and TEF/EA (2.7% of cases). The proportion of cases with additional midline defects or VATER or VACTERL type anomalies was similar for all three defects, suggesting a common developmental pathogenesis. Epidemiologic differences between defects, and between types within defects, may reflect differences in timing of the pathological process or differences in susceptibilities (e.g., by sex or aneuploidy) and emphasize the need to evaluate each defect and its types separately in epidemiologic studies.

Abstract
Epidemiologic data were analyzed for a total of 2,693 infants with esophageal atresia registered in nine congenital malformation registries around the world. The average recorded prevalence at birth was 2.6 per 10,000 births, with a significant variability among programs--and sometimes within a program--and a maximum prevalence of above 3 per 10,000 births. Clusters of infants with esophageal atresia were observed but may be random. An increasing rate was seen during the period 1965 to 1975 (Norway, South America, Sweden). The type of esophageal atresia was specified in only 439 cases, but no major differences were seen in the epidemiologic characteristics of infants with the most common type (distal fistula) and infants with other types. There was an excess of low birth weight and preterm birth, and infants with esophageal atresia had a birth weight 500 to 1,000 g less than normal infants in each gestational week. There was an excess of twins, apparently mainly or exclusively due to monozygotic twinning, but in only two pairs did both twins have esophageal atresia. There was no effect seen of maternal age, but low parity, irrespective of maternal age, was associated with an increased risk for esophageal atresia. Infant survival varied among programs and depended heavily on associated malformations. Among 1,107 sibs born before the proband and 385 born after the proband, only 25 (1.7%) had a serious malformation; three had esophageal atresia. In 57.3% of the infants with esophageal atresia, no other malformations were present, in 36.4% other major malformations were recorded, and in 6.3% there were chromosomal anomalies. The malformations present associated with esophageal atresia were analyzed: a large proportion entered the constellation sometimes called "caudal mesoderm spectrum of malformations": VATER, Potter, and caudal regression sequences.

Abstract
The purpose of this study is to explore the use of the scan test to detect temporal clustering of poison control center data. We applied the scan test to a computerized data set consisting of all cases of carbon monoxide poisoning reported to our Poison Control Center in 1988. Using a time window of three days, the scan test identified three statistically significant temporal clusters. A review of case and climatologic data revealed that two of the clusters were due to family outbreaks and one was due to a sudden cold spell. We conclude that the scan test is a potentially useful surveillance tool which can be easily applied to poison control center data.

Abstract
There has been a suggestion that esophageal atresia with tracheoesophageal fistula (EA/TEF) may be related to the occurrence of infectious disease in the population during the time of early gestation. There is therefore a need for further data on trends in incidence related to infectious diseases. Data on the occurrence of EA/TEF with and without additional congenital malformations may also be relevant. The British Columbia Health Surveillance Registry is population-based with excellent case ascertainment of birth defects, and data are available on the incidence of infectious diseases for B.C., allowing comparison of trends to be made. One hundred forty-nine cases of EA/TEF occurred among 534,834 consecutive livebirths during the period 1966-1980 for an incidence rate of 1/3,590. No significant (p less than 0.05) annual, seasonal or monthly incidence trends were observed. In addition, the occurrence of EA/TEF could not be correlated with the prior incidence of infectious hepatitis, rubella, salmonella, or rubeola. Fifty-five percent of individuals with EA/TEF had congenital malformations in other systems, most frequently cardiovascular, gastrointestinal, and genitourinary. Most individuals with additional congenital malformations had multiple system involvement.

Abstract
The scan statistic evaluates whether an apparent cluster of disease in time is due to chance. The statistic employs a 'moving window' of length w and finds the maximum number of cases revealed through the window as it scans or slides over the entire time period T. Computation of the probability of observing a certain size cluster, under the hypothesis of a uniform distribution, is infeasible when N, the total number of events, is large, and w is of moderate or small size relative to T. We give an approximation that is an asymptotic upper bound, easy to compute, and, for the purposes of hypothesis testing, more accurate than other approximations presented in the literature. The approximation applies both when N is fixed, and when N has a Poisson distribution. We illustrate the procedure on a data set of trisomic spontaneous abortions observed in a two year period in New York City.

Abstract
A study group of 160 index patients with isolated esophageal atresia, a control group of 160 matched healthy controls, and the first-degree relatives of patients and controls were examined; epidemiological, family planning, teratological, and genetic data were obtained by personal interview in the study and control groups. One half of the index patients were male. Intrauterine growth retardation, a higher proportion of mothers under 19 or over 30 years of age, and less skilled professions of the parents were found in the study group. There were more extramarital conceptions, more pregnancies in spite of the use of contraceptive pills, and more delayed conceptions in index patients' mothers. The teratogens studied did not have an obvious pathological effect here. The sib occurrence of isolated esophageal atresia was 0.43%, which did not correspond too well to the expected figure of 1.34% based on the polygenic model.

Abstract
Tracheal agenesis is a rare malformation of the lower respiratory tract. Investigation of a patient with multiple congenital anomalies and tracheal agenesis prompted a review of the literature which uncovered 42 previously published cases, most of whom had other defects. The presence in our patient of a tracheal abnormality in association with radial hypoplasia, single umbilical artery, tetralogy of Fallot, and left hydroureter initially suggested presence of the VACTERL association. However, numerical classification of malformation patterns in the reported patients with tracheal agenesis and in a series of patients with tracheoesophageal fistula and other components of the VACTERL association suggests that tracheal agenesis does not occur in the VACTERL association and may be part of another pattern of malformations which includes laryngeal atresia, complex congenital heart anomalies, radial ray defects, and duodenal atresia.
