Various systemic diseases and conditions have been associated with an increase in periodontal disease severity. These studies indicate that host-response mechanisms influence the initiation and/or progression of inflammatory periodontal diseases. Diseases that have been associated with an increased severity of periodontal disease include various neutrophil abnormalities, Down's syndrome, diabetes, and recently, the acquired immunodeficiency syndrome. Sickle cell disease is strongly associated with a predisposition to various infections; therefore, the objective of this study was to determine whether sickle cell disease is also associated with an increase in the severity of periodontal disease. A total of 78 patients with sickle cell anemia (SS), hemoglobin SC disease (SC) or S Thalassemia were evaluated blind and compared with an appropriate control population using clinical and radiographic indices of periodontal disease severity. The results clearly indicate that, in this population of patients, sickle cell disease is not associated with increased levels of gingivitis or periodontitis.

In a pilot study, on a hospital-based series consisting of 285 type 1 and 282 type 2 patients with Diabetes Mellitus (DM) we compared the month-of-birth with the standard birth curve. In accordance with a previous investigation on 23,620 diabetics in the Netherlands, we found an excess of DM births in the first quarter of the year (p less than 0.005) and a deficiency of them during the last one. This excess corresponds with conceptions during the spring restoration of the ovulatory pattern, this deficiency with conceptions during its winter stabilization. Identical peaks and troughs have been found in month-of-birth studies of individuals with chromosomal anomalies and with anencephaly. Similarly, ovopathy--which we consider a common cause for multiple anomalies--can explain the high incidence of DM in Down's syndrome as well as in other chromosomal aberrations, and its association with unusual dermatoglyphics. Furthermore, the ovopathy concept appears in line with the consistently found maternal age and parity effect, the discordancy in one-egg twins and the distortion of HLA-DR phenotype distribution in IDDM multiplex families. Although our conclusions must be guarded because of sample bias and doubts concerning precise classification, we found that the configurations were stronger in the type 2 DM sample. Ovopathy might prove to be the crucial environmental factor in the causation of IDDM--searched for by many scholars--and a common cause for both types. The HLA-DR haplotypes might rather be the "trigger", influencing the course and type of the disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Genetic and environmental factors (breast feeding, probably viral infections) play a role in the expression of the disease. Prevalence of GSE in childhood did not substantially decrease in the last 15 years in all European countries, where GSE is still more common in infantile age and presents frequently gastrointestinal symptoms. A decrease has been reported in childhood in several United Kingdom areas and in Finland, where the clinical presentation is changing, shifting upward with age and coming closer to the adult type of the disease. The following clinical problems have been reported in the recent literature: enamel hypoplasia; monosymptomatic short stature; arthritis and other immunologic diseases; association with diabetes, atopy, Iga deficiency, and probably Down's syndrome. Delay in puberty and other peculiar problems of the disease have been described in adolescents. Tests assessing the permeability of the small intestine and the blood levels of antigliadin antibodies have recently gained success as noninvasive tools for the diagnosis of the GSE. The gluten should be withdrawn from the diet and the challenge with gluten should be performed not before 12 months of gluten-free diet with an accurate timing of the biopsy on the basis of the antigliadin and antireticulin antibodies, to avoid clinical and growth damage. Celiac children do require a permanent gluten-free (and not poor) diet. In reality, too many celiac adolescents are off-diet.

Grandmultiparity is reported to increase both maternal and perinatal mortality and morbidity. Unique religious and demographic factors in Jerusalem allowed us to analyze a population wherein parity could be dissociated from socioeconomic status. A total of 7785 mothers was studied, 889 (11.5%) of whom were grandmultiparas. Comparison of grandmultiparous mothers with all others revealed no increase in the incidence of hypertension, diabetes, uterine atonia, antenatal or postnatal hemorrhage, cesarean sections, stillbirth rate, or congenital malformations. The grandmultipara had significantly lower neonatal mortality and low birth weight rates and a significantly higher incidence of multiple births and trisomy 21 (p less than 0.01). These results strongly suggest that grandmultiparity in and of itself in a healthy, economically stable population afforded modern medical care is not a major risk factor and that previous reports primarily reflected social class factors and not parity per se.

All 995 persons with Down's syndrome who died in the United States during 1976 and whose death certificates listed Down's syndrome as the underlying or a contributing cause of death were identified. This allowed the underlying causes of death of 793 affected persons to be analysed and compared to deaths in the whole US population for that year. Mortality ratios provided evidence that the excess risk of leukemia mortality continues into adulthood and that deaths from other hematopoietic malignancies also occur excessively among Down's syndrome adults. Congenital anomalies of all kinds in infancy and congenital defects of the heart in infancy and later were also excessive. Respiratory tract infections and pneumonia showed persistently high ratios. Diabetes was raised only at ages 24 to 34 years. Ischemic heart disease, non-hematopoietic cancers, accidents, suicides and violence were under-represented among the causes of death. Methodological limitations of proportional mortality analysis are discussed.

NAD levels markedly increase upon mitogen stimulation of lymphocytes from young subjects. In contrast, lymphocytes from old subjects do not increase NAD levels upon stimulation. A survey of 35 individuals aged 18-79 years revealed a significant age-dependent decrease in the NAD response to mitogen stimulation. No significant differences were noted in lymphocytes from age-matched individuals with Down's syndrome or diabetes mellitus. On the other hand, cultured skin fibroblasts showed elevated NAD levels with age. However, this effect appears to be due to increased size of the cells since the NAD/protein ratio is unchanged. Skin fibroblasts from patients with progeria exhibit much higher levels of NAD and protein per cell than age-matched controls.

We determined retrospectively the frequency and risk of hyperglycemia in 421 children with leukemia who had received L-asparaginase and prednisone as part of their remission induction therapy. Forty-one patients (9.7%) developed this complication, 39 within one week after the first dose of L-asparaginase. Hyperglycemia resolved in all patients and in 32 before the end of the four-week induction period. Age, obesity, and Down syndrome each had a significant bearing on the frequency of hyperglycemia. Children 10 years of age or older were more likely to develop the complication than were younger children. When more than one factor was present in a child, the risk of hyperglycemia increased significantly. A family history of diabetes mellitus also appeared related to an increased risk of hyperglycemia. Childhood leukemia patients with any of the risk factors identified here should be closely monitored for glucosuria while receiving prednisone and L-asparaginase for remission induction.

This prospective study investigates the relationship between insulin-dependent diabetes and maternal serum levels of alpha-fetoprotein (AFP), unconjugated oestriol (uE3), and human chorionic gonadotropin (hCG). It also examines the potential impact on screening for Down syndrome. The population-based cohort included 20,321 pregnant women in Maine who underwent routine serum screening for Down syndrome in the second trimester. The cohort included 52 women with insulin-dependent diabetes. Maternal serum AFP levels are now routinely adjusted for insulin-dependent diabetes. These adjustments, therefore, were made routinely in the diabetic women, but no equivalent adjustments were made for uE3 and hCG values. The initial false-positive rate (using all three markers) among the women with diabetes was not significantly different from that in the non-diabetic population (7.7 and 5.4 per cent, respectively). Prior to adjustment for insulin-dependent diabetes, the median AFP level in the 52 women was 0.73 multiples of the median (MOM); the median levels of uE3 and hCG were 0.93 and 0.98 MOM, respectively. When the uE3 and hCG levels were adjusted, the initial false-positive rate was unchanged. Median serum levels of uE3 were significantly higher in the 33 women whose onset of diabetes was prior to 19 years of age (0.99 MOM) than in the 19 women whose onset of diabetes was at age 19 or older (0.84 MOM). This is the first population-based study to investigate the relationship between diabetes and serum levels of AFP, uE3, and hCG, and confirms earlier observations from a case-control study that found only slightly lower uE3 and hCG levels.

A study was performed to investigate the concentrations of the alpha and beta free sub-units of human chorionic gonadotrophin (free alpha-hCG and free beta-hCG) in maternal serum between 15 and 22 weeks of pregnancy in 126 pregnancies among 92 women with insulin-dependent diabetes mellitus (IDDM). Each IDDM pregnancy was matched with two control singleton pregnancies for gestational age (same completed week) and duration of sample storage (same calendar quarter). The median free alpha-hCG level in the IDDM pregnancies was 0.86 multiples of the median (MOM) for pregnancies without IDDM at the same gestational age (P < 0.002) (95 per cent confidence interval 0.80-0.94). The corresponding free beta-hCG level was 0.96 MOM (95 per cent confidence interval 0.85-1.09). These results enable free alpha-hCG values to be adjusted so that antenatal screening for Down's syndrome can be performed using this marker in IDDM pregnancies as well as in non-diabetic pregnancies.

The use of maternal age alone to identify pregnant mothers at risk of a fetus with Down's syndrome has recently been supplemented by maternal serum screening using biochemical markers such as alpha-protein, human chorionic gonadotrophin and oestriol. These tests have been reported to increase the sensitivity of antenatal detection of such fetuses from 35% to 67% with a false positive rate of 5%. However, these maternal serum markers may be affected by maternal weight, the smoking history of mothers and diabetes mellitus. Furthermore, such sensitivities are achieved only when gestational age is assessed accurately by ultrasound. Many further studies need to be carried out before the introduction of maternal serum screening into routine obstetric practice in Singapore. These include studies on the incidence of Down's syndrome in the local population, studies on the distribution of these serum markers in the second trimester of pregnancy, sensitivities and positive predictive values of such a test in the local population as well as the socio-economic implications of implementing such a screening test in the local obstetric population.
