Parents of 751 children affected by cancer/leukemia, congenital heart disease, strawberry nevus or mental retardation have been investigated with respect to their reproductive history and their exposure to risk factors for spontaneous abortion. Differences between the four groups were established for the number of children in the sibship, the proportion of multigravidae and the spontaneous abortion rate among these women. The greatest differences were observed in the two groups of malformed children compared with the other two groups, being as marked in those with a severe malformation (heart defect) as in those with a benign one (strawberry nevus). Taking known risk factors for spontaneous abortion into account did not explain the observed differences. An etiological hypothesis is put forward which takes account of the high proportion of quantitative abnormalities of the karyotype associated with congenital heart disease and spontaneous abortion.

Using data from the Tri-State and a mathematical model, the hypothesis that low levels of diagnostic radiation can produce both leukemia and heart disease has been tested. The range of radiation considered is within a factor of 10 of 5 rads (0.5-50 rads). Even at the lowest levels, an estimated 5% of the persons exposed suffer damage to the DNA which is subsequently expressed as heart disease or leukemia. The risk of heart disease in an affected group is roughly tripled and there is a 10-fold increase in the risk of leukemia according to preliminary estimates.

Nine cases have been presented in detail to illustrate some of the varied causes of sudden neurological deficit in childhood: arteriovenous malformation, cryptic hamartoma, berry aneurysm, mycotic aneurysm, intraspinal arteriovenous malformation, brain tumor, migraine, arteritis, and multiple sclerosis. The Boston Children's Hospital experience with aneurysms and intracranial arteriovenous malformation has been summarized. It is noteworthy that a cutaneous hemangioma overlay one cranial and one intraspinal arteriovenous malformation. One small but deep cerebral arteriovenous malformation apparently destroyed itself after its second hemorrhage. Not only have multiple sclerosis and a brain tumor mimicked a vascular lesion, but a series of vascular accidents was misdiagnosed first as multiple sclerosis then as a thalamic tumor. The many possible causes of childhood strokes has been thoroughly cataloged in the Report of the Joint Committee for Stroke Facilities in 1973 (11). Children may be more susceptible to strokes because of congenital abnormalities such as congenital heart disease, hemophilia, and sickle cell anemia, or by diseases which more commonly occur in this age group, such as leukemia. The likelihood of brain abscess in cyanotic congenital heart disease is stressed. Arteriographic studies in our series have been safe; however, there have been reports of probable worsening of symptoms in children with multiple cerebral occlusive lesions in the presence of homocystinuria.

In the Tri-State Leukemia Survey, the history of diseases in 605 adult male leukemia cases 15 years and older and in 668 adult male population controls was examined. These diseases occurred at least 1 year before leukemia was diagnosed. The data were based on respondents' answers that the disease was diagnosed by a physician; the respondent was either the subject or his spouse. Of 30 diseases studied, 7 showed an excess among the patients with leukemia: infectious hepatitis, eczema, psoriasis, diabetes, arthritis and rheumatism, heart disease, and ankylosing spondylitis. Mumps had a lower reported occurrence among the cases, whereas pneumonia was less frequent in acute lymphatic cases than in population controls. Three diseases occurred significantly less in controls than in persons with specific histologic types of leukemia. Our data revealed a more frequent history of herpes zoster (shingles) in chronic lymphatic leukemia, more hives in acute chronic myeloid cases, and meningitis in acute myeloid leukemia. When we only considered the patients' responses, more of them admitted having had acne than did our controls. The remaining diseases--childhood viral diseases, infectious mononucleosis, smallpox, typhoid fever, dysentery, scarlet fever, tuberculosis, asthma, hay fever, and goiter did not occur more frequently in cases than in controls. The findings were consistent with evidence from previous laboratory and clinical studies. The increased occurrence of infectious hepatitis in our case series is consistent with the findings of other studies showing an increased frequency of Australia antigen in patients with hepatitis, leukemia, and Down's syndrome.

The optimum and critical hemoglobin concentrations are determined by the oxygen demand of the tissues and several oxygen transport parameters (i.e., blood flow, arterial oxygen saturation, oxygen affinity of hemoglobin, and the critical venous oxygen pressure). Most of the oxygen transport parameters change markedly during the first weeks after birth. Oxygen consumption and cardiac output in neonates are three times those of adults on a body weight basis. Due to the high oxygen affinity of fetal hemoglobin, the oxygen unloading capacity of hemoglobin in neonates is about 50% less than in adults. From oxygen transport parameters and oxygen consumption we have calculated the optimum and the critical hemoglobin concentrations for preterm and full-term neonates during the first weeks after birth. A hemoglobin concentration of 15 g/dl appears optimal for preterm and full-term infants at birth as well as for adults. The calculated minimum acceptable hemoglobin concentration is 6 g/dl for children and adults, 12 g/dl for preterm infants and 11 g/dl for full-term neonates at birth. Due to the postnatal decrease in oxygen affinity, the minimum acceptable hemoglobin concentration decreases by approximately 1 g/dl/week for the first 5-6 weeks until the minimum value of 6 g/dl for children and adults is reached. The minimum hemoglobin concentration should be 2 g/dl higher in patients who require increased oxygen or suffer from other serious disorders. A minimum hemoglobin concentration of 10 g/dl is recommended in children with leukemia or other oncological disease. In infants and children with chronic hypoxemia (cyanotic congenital heart disease) the minimum hemoglobin concentration should be increased by the percentage of arterial oxygen desaturation.

Recombinant inbred (RI) strains of mice and the closely related recombinant congenic strains offer considerable promise for identifying and characterizing genes causally associated with many different diseases. Loci associated with diseases such as heart disease, autoimmune disease and leukemia have already been identified through the use of these unique strains.

To explore whether exposure among firefighters to fire smoke could lead to an increased risk of cancer, lung disease, and heart disease, the mortality of 4546 firefighters who were employed by the cities of Seattle and Tacoma, WA and Portland, OR for at least one year between 1944 and 1979 were compared with United States national mortalities and with mortality of police officers from the same cities. Between 1945 and 1989, 1169 deaths occurred in the study population and 1162 death certificates (99%) were collected. Mortality due to all causes, ischaemic heart disease, and most other non-malignant diseases was less than expected based upon United States rates for white men. There was no excess risk of overall mortality from cancer but excesses of brain tumours (standardised mortality ratio (SMR) = 2.09, 95% confidence interval (95% CI) 1.3-3.2) and lymphatic and haematopoietic cancers (SMR = 1.31, 95% CI = 0.9-1.8) were found. Younger firefighters (< 40 years of age) appeared to have an excess risk of cancer (SMR = 1.45, 95% CI 0.8-2.39), primarily due to brain cancer (SMR = 3.75, 95% CI 1.2-8.7). The risk of lymphatic and haematopoietic cancers was greatest for men with at least 30 years of exposed employment (SMR = 2.05, 95% CI 1.1-3.6), especially for leukaemia (SMR = 2.60, 95% CI 1.0-5.4).

Among the TORCH agents, the occurrence of rubella and human T-lymphotropic virus type 1 (HTLV-1) in Japan were studied. Rubella epidemics occurred throughout Japan from 1964 to 1969 and from 1975 to 1979. Low prevalences of CRS were observed in northeastern Japan, and high prevalences in southwestern Japan, with the highest in Okinawa. These conditions could be explained by the lower rate of rubella H1 antibody in the female population of southwestern Japan. Time of maternal rubella was in the gestational age interval from 26 to 57 days for cataract, from 25 to 62 days for heart disease and from 16 to 131 days for deafness. HTLV-1 is the causative agent of adult T-cell leukemia. Main route of transmission of this virus is mother-to-child transmission, through breast milk. Among the 311 mother-child pairs in Okinawa, 65 mothers (20.9%) and 10 children (3.2%) were seropositive for HTLV-1. Ten (15.4%) of the 65 seropositive mothers had seropositive children. These children had acquired their HTLV-1 antibodies by the age of 3 years. A significant difference existed between the prevalence rate of HTLV-1 antibodies in mothers and children.

Down syndrome (DS) is a major cause of congenital heart and gut disease and mental retardation. DS individuals also have characteristic facies, hands, and dermatoglyphics, in addition to abnormalities of the immune system, an increased risk of leukemia, and an Alzheimer-like dementia. Although their molecular basis is unknown, recent work on patients with DS and partial duplications of chromosome 21 has suggested small chromosomal regions located in band q22 that are likely to contain the genes for some of these features. We now extend these analyses to define molecular markers for the congenital heart disease, the duodenal stenosis, and an "overlap" region for the facial and some of the skeletal features. We report the clinical, cytogenetic, and molecular analysis of two patients. The first is DUP21JS, who carries both a partial duplication of chromosome 21, including the region 21q21.1-q22.13, or proximal q22.2, and DS features including duodenal stenosis. Using quantitative Southern blot dosage analysis and 15 DNA sequences unique to chromosome 21, we have defined the molecular extent of the duplication. This includes the region defined by DNA sequences for APP (amyloid precursor protein), SOD1 (CuZn superoxide dismutase), D21S47, SF57, D21S17, D21S55, D21S3, and D21S15 and excludes the regions defined by DNA sequences for D21S16, D21S46, D21S1, D21S19, BCE I (breast cancer estrogen-inducible gene), D21S39, and D21S44. Using similar techniques, we have also defined the region duplicated in the second case occurring in a family carrying a translocation associated with DS and congenital heart disease. This region includes DNA sequences for D21S55 and D21S3 and excludes DNA sequences for D21S47 and D21S17.(ABSTRACT TRUNCATED AT 250 WORDS)

Since January 1988, 91 children with ANLL have been treated with a polychemotherapy regimen containing Mitoxantrone (MTZ), excluding other anthracyclines. Induction consisted of Ara-C, MTZ, and VP 16. Consolidation lasted 6 weeks with Vincristine, MTZ, Ara-C and 6-thioguanine (6TG), and was followed by 2 intensification courses combining High-dose Ara-C with respectively MTZ or VP 16. Maintenance therapy associated 6TG, Ara-C and MTZ up to a cumulative dose of 150 mg/m2. 91 patients are evaluable: 70 (76.9%) achieved complete remission, 59 (64.8%) after induction alone. There were 7 early deaths, 5 deaths in complete remission, and 17 relapses. Major toxic side effects were observed during the consolidation phase, mainly infectious complications, and the median duration of neutropenia was 82 days in this phase, leading to decrease the MTZ dose from 10 to 8 mg/m2. The event-free survival at three years is 38%. Cardiac toxicity is presently absent in children without previous cardiopathy.
