Homicide among black males in Jefferson County, Alabama 1978-1989.

This study examined 1505 of 1573 (96%) homicides occurring in Jefferson County, Alabama, between 1978 and 1989, that were investigated by the Coroner/Medical Examiners' Office. During this 12 year period, Jefferson County's average annual homicide rate was 18.9 per 100,000 compared to an 11.3 per 100,000 State of Alabama's rate and a 9.3 per 100,000 US rate. In Jefferson County, the average annual homicide rate among blacks (41.4) was almost six times the rate among whites (7.1). The highest average annual race-specific homicide rate was in black males (75.9), followed by black females (12.4), white males (10.4) and white females (4.1). Black males in the 25-34 year age group had the highest rate (159.7), followed by black males in the 35-44 year age group (151.7) and then by black males in the 15-24 year age group (96.2). These rates ranged from almost eight to over eleven times the rates of similarly aged, black females or white males and were over 33 times higher than the rates for white females of the same age. Our results emphasize the high rates of black male on black male violence, the acquaintance of the black male victim and perpetrator, and the importance of arguments as an inciting event. Moreover, we determined that while the raw numbers and rates for black homicides were and are staggering, the average annual homicide rate for black males was actually declining at a greater rate than for all other race-sex groups. Further, our results suggest that a number of hypothesized determinants commonly believed to be associated with the increase in the homicide rate among black males between 15 and 24 years of age, such as drug use, increased availability of firearms and increased child abuse were not, in fact, major determinants of the change in homicide rates.

Increased incidence of insulin-dependent diabetes mellitus following an epidemic of Coxsackievirus B5.

In order to address the hypothesis that coxsackievirus B5 is a cause of insulin-dependent diabetes mellitus (IDDM), the incidence of IDDM was examined following an epidemic of coxsackievirus B5 in Jefferson County, Alabama. Incidence estimates were obtained from a registry of IDDM which was maintained in the county since 1979. A total of 266 cases were diagnosed (69 black and 197 white individuals less than 20 years of age) between 1979 and 1988. Significant increases in incidence were observed in both races, corresponding temporally to the epidemic of coxsackievirus B5 which occurred in 1983. The overall incidence in the year beginning July 1983, the month of the first isolation of coxsackievirus B5, was 18.4/100,000 person-years, an excess of 6.7/100,000 person-years over the average annual incidence for the previous 4 years. The increase was greatest in females and among all children aged 10-14 years. This study provides support for the role of coxsackievirus B5 in the multifactorial etiology of IDDM, and suggests a possible basis for the increased incidence of IDDM reported around the world in the early 1980s.

Gestational diabetes mellitus among African-American women.

Gestational diabetes mellitus (GDM) is associated with increased risk of poor outcomes for the pregnancy. It is a strong risk factor for subsequent diabetes. The epidemiology of GDM in African-American women is not well known. It has not been demonstrated that their risk factors are similar in character and weight to those among White women. There is considerable multicollinearity among GDM risk factors such as age, parity, obesity, hypertension, and family history of diabetes, and this needs to be sorted out. This review is based on the results of a nested case-control study to evaluate the frequency of, and the relationships of the known risk factors with, the onset of GDM among African-American women. All cases of GDM within a cohort of women seen at any of the county health department clinics in Jefferson County, Alabama from 1981 to 1987 were identified. The cohort represents approximately 63% of all African-American pregnancies in the county during the period. With few exceptions (5.1% based on fasting plasma glucose greater than or equal to 120 mg/dl), potential GDM cases (7.1%) were selected on the basis of a 2 h post 100 g carbohydrate meal screening plasma glucose measure at their second prenatal visit and again at 28-32 weeks greater than or equal to 115 mg/dl and diagnosed on the basis of the results of an oral glucose tolerance test (OGTT) using the criteria of O'Sullivan and Mahan. Women with any prior history of diabetes (even in pregnancy), 1.6%, were excluded. The frequency of the new diagnosis of GDM among African-American women in this pregnancy in the cohort was 2.5% of pregnancies and 3.4% of women, which is similar to the values reported in the other studies. Controls were selected from women with negative screening tests who delivered after a GDM subject. The results reported in this paper reflect 358 cases (86% of all eligible GDM cases identified) and 273 controls. Cases were significantly older (28.3 vs. 21.7 years), of higher gravidity (2.7 vs. 1.9), more obese (76.7 vs. 61.7 kg), gained weight more rapidly (0.34 vs. 0.28 kg/week), had more hypertension in this pregnancy (28.2 vs. 2.6%), and there was a higher proportion with a family history of diabetes (41.3 vs. 16.5%) (p less than 0.001 for all comparisons). Because there were significant correlations among the risk factors in both cases and controls, multivariable logistic regression analyses were performed.(ABSTRACT TRUNCATED AT 400 WORDS)

The relationship between maternal serum zinc levels during pregnancy and birthweight.

A retrospective follow-up study to ascertain the relationship between the level of serum zinc and its rate of change during gestation and birthweight was conducted in 476 women of lower socioeconomic status. Serum zinc concentrations measured at approximately 16 (early) and 32 weeks (later) in gestation were both found to be significant predictors of birthweight. Even after controlling for gestational age at birth and other determinants of birthweight, for each microgram/dl increase in serum zinc early and later in pregnancy, birthweight increased by 5.8 and 8.6 g, respectively. Furthermore, after adjustment for initial zinc levels both the total change (beta = -7.0, P = 0.0007) and the rate of change (beta = -60.8, P = 0.007) in serum zinc during pregnancy were inversely associated with birthweight, i.e., the larger the fall in serum zinc during pregnancy, the smaller the infant. Low serum zinc level (less than 60 micrograms/dl) late in pregnancy was associated with greater than a five-fold increase in the odds (OR = 5.8, 95% CI = 1.8, 16.4) of giving birth to a low birthweight infant. The results of this study suggest a threshold for maternal serum zinc below which the prevalence of low birthweight increases rapidly.

Relation of risk factor levels in young adulthood to parental history of disease. The CARDIA study.

BACKGROUND: The relation between self-reported parental disease and risk factor levels was examined in 2,637 black and 2,478 white men and women aged 18-30 years at the Coronary Artery Risk Development in Young Adults (CARDIA) Study baseline examination (1985-1986). METHODS AND RESULTS: The prevalence of parental disease (at least one parent) in white versus black participants was 44% and 56% for hypertension, 47% and 44% for obesity, 16% and 13% for myocardial infarction, 11% and 17% for diabetes, and 6% and 10% for stroke, respectively. Among these young adults, parental hypertension was associated with higher sex- and age-adjusted systolic and diastolic blood pressure levels. Parental myocardial infarction was associated with higher plasma cholesterol, higher blood pressure levels, and lower high density lipoprotein cholesterol levels in white participants. Parental diabetes was associated with higher fasting blood glucose and insulin levels in all race-sex groups and with higher triglycerides and lower high density lipoprotein cholesterol in black participants only. Parental history of obesity was related to less favorable age- and sex-adjusted lipid levels in white participants and higher blood pressure levels in black participants. Parental history of stroke was associated with higher systolic blood pressure levels in black participants. In general, these differences across family history were predicted only in part by obesity. The prevalence of more than one disease reported in parents occurred more frequently than would have been expected due to chance alone. CONCLUSIONS: These associations between parental disease and risk factors in their adult children probably reflects the impact of both environmental and genetic factors. Parental history may be a useful marker for high risk individuals.

Epidemiology of childhood IDDM in U.S. Virgin Islands from 1979 to 1988. Evidence of an epidemic in early 1980s and variation by degree of racial admixture.

OBJECTIVE: The epidemiology of insulin-dependent diabetes mellitus (IDDM) was evaluated in a predominantly black population in the U.S. Virgin Islands. RESEARCH DESIGN AND METHODS: Primary ascertainment of diabetic subjects was by retrospective review of hospital and clinic records, and IDDM was defined by Diabetes Epidemiology Research International Group criteria. RESULTS: For the period 1979-1988, 28 children less than 15 yr of age were diagnosed with IDDM resulting in an average annual IDDM incidence rate (IR) of 7.5/100,000 (95% confidence interval 4.7-10.3). A significant increase in IDDM incidence (P less than 0.01) was observed when the IR rose to 28.4/100,000 in 1984. White children had the highest IR (28.9/100,000). The IR for Hispanics (7.2/100,000) was slightly higher than that for blacks (5.9/100,000). Among black children, a slight but nonsignificant male excess in incidence was observed (male-female ratio 1.5). When black or Hispanic patients were compared with age-matched control subjects with respect to grandparental race, the diabetic subjects had a greater percentage of white ancestry (P less than 0.02 and P less than 0.05, respectively). The incidence of IDDM in Caribbean blacks (West Indians) in the U.S. Virgin Islands was similar to blacks in the U.S. CONCLUSIONS: The epidemic of IDDM in 1984 provides support for a possible pandemic in the early 1980s.

Development of a registry for diabetes in persons 0-19 years of age in the U.S. Virgin Islands.

A juvenile-onset diabetes registry was recently established in the United States Virgin Islands. Hospital and clinic records were used as the primary sources of case data, while data procured through a physician survey and mass media campaign were used to assess the completeness and validity of the registry listings. The data indicated that 39 people 0-19 years old developed diabetes during the study period (1 January 1979-31 December 1988), of whom 36 probably had Type 1 diabetes. Completeness of the primary source data was estimated at 92.3% and validity seemed very good (around 100%). Evaluation of these registry data has provided new insights into the epidemiology of Type 1 diabetes in the U.S. Virgin Islands.

A positive association between maternal serum zinc concentration and birth weight.

A study was conducted on a cohort of 476 women (364 black, 112 white), who attended the Jefferson County Health Department clinic for their prenatal care, to ascertain the relationship between maternal serum zinc concentration measured early in pregnancy and birth weight. For all subjects maternal serum zinc was significantly related to birth weight after various independent determinants of birth weight were controlled for. The data in this study indicate a threshold for maternal serum zinc concentration below which the prevalence of low birth weight increases significantly. Pregnant women who had serum zinc concentrations in the lowest quartile had significantly higher prevalence of low birth weight than did those mothers who had serum zinc concentrations in the upper three quartiles during pregnancy. These findings suggest that maternal serum zinc concentration measured early in pregnancy could be used to identify those women at higher risk of giving birth to a low-birth-weight infant.

Epidemiology of IDDM in black and white children in Jefferson County, Alabama, 1979-1985.

For the period of 1 January 1979 through 31 December 1985, an average annual incidence rate (IR) of 12.1/100,000 (95% confidence interval [10.4/100,000, 14.0/100,000]) of insulin-dependent diabetes mellitus (IDDM) was observed in Jefferson County, Alabama, among people less than 20 yr old. Hospital medical-record review was the primary source of case ascertainment. A large proportion of Black children in the county permitted race-specific analyses. The average annual IR among the Black children was less than half that observed in the White children (7.0/100,000 vs. 15.6/100,000, respectively). Nearly equal numbers of White boys and girls were diagnosed during this period; however, there were three times as many Black girls as Black boys diagnosed. Among the 134 Whites, age-specific annual IRs were highest in the 5- to 9- and 10- to 14-yr age groups. Little variation was observed in age-specific rates among the 41 Black subjects. A seasonal trend was evident in both races, with the fewest cases of IDDM diagnosed in the months of April through June (P less than .001). No association between the incidence of diabetes and income level was found among White or Black children. Significant differences in the epidemiology of IDDM between White and Black children suggest an important avenue for studying the etiology of IDDM.

The effect of risk assessment in conjunction with health promotion education on compliance with preventive behaviors.

In this study, 55 subjects were given prevention-oriented recommendations from general, detailed nutritional, and Type A personality risk assessments in conjunction with health promotion education. Changes in compliance with health behaviors were measured 13 months after the first assessment, using the same three risk assessment instruments. Based on self-report, a statistically significant number of persons changed from noncompliance to compliance on three nutritional behaviors, three behaviors related to health-promoting exercise and recreation, and one medical screening behavior. A statistically significant reduction in mean from the first to second year was observed for daily sodium intake and percent of calories from fat, and a significant increase in mean percent of time using seatbelts. Though limited by study design, the results provide encouraging evidence in support of the proposition that risk assessment in conjunction with health promotion education can effect positive change in preventive behaviors.

Regression of locally recurrent squamous cell carcinoma of the skin following excision of a metastasis: with review of the literature.

The spontaneous regression of a malignant tumor subsequent to surgical excision of a distant cancer is a fascinating observation. Although rare, this dynamic tumor/host relationship may offer important insight into mechanisms of immunologic surveillance. A better understanding of that interaction may help identify specific aberrations that predisposes to cancer development. Although the literature cites several histologically distinct cancers that demonstrate this phenomenon, a report of spontaneous regression of squamous cancer of the skin has not previously appeared. The case presented serves as the focal point for discussion of current concepts pertaining to this apparent host/tumor interaction.

Epidemiology of acute necrotizing ulcerative gingivitis.

In the last 60 years, there have been approximately 50 studies of various suspected risk factors associated with acute necrotizing ulcerative gingivitis. Two thirds of these studies have been either surveys or case reports; nearly all the rest have been case-control studies. There have been only a few longitudinal and population-based studies, most of which were in high-risk populations. The findings of many studies pertain to gingivitis in general rather than in acute necrotizing ulcerative gingivitis in particular; the findings of other studies are based on small numbers or solely on case histories without the inclusion of control subjects. There are comparisons between the epidemiology of acute necrotizing ulcerative gingivitis as it occurs in military populations and the epidemiology of meningococcal meningitis (98-103). Both diseases have been reported in closed communities such as in young recruits away from home and in new surroundings. A temporal trend upward in disease frequency was described for both infections during World War II. Both infections appear to be characterized by low communicability, with no documented transmission by fomites or vectors. Furthermore, active disease in both cases is associated with markedly increased numbers of normally indigenous flora: B. intermedius in the case of acute necrotizing ulcerative gingivitis and Neisseria meningococcus in the case of epidemic meningococcal meningitis. Risk factors associated with both diseases include crowding, physical fatigue, increased stress, low socioeconomic status, and failure of host defense mechanisms. In general, there is potential for longitudinal studies of young people such as new military recruits and college students who are undergoing the transition from dependence to independence. It is intriguing that these young adults are suddenly at increased risk of this disease in late adolescence when they should be at peak fitness and, just as suddenly, at decreased risk after their early thirties. It appears that the dynamic tension between bacterial agents, environmental stressors, and host defense mechanisms is abruptly altered in certain young people, allowing the characteristic lesions to develop. Furthermore it appears that, in the United States at least, the disruption is limited primarily to white people relative to black people. It is possible that disease develops because young adults are brought together from diverse locations and perhaps exposed to a new microbial agent. However, acute necrotizing ulcerative gingivitis has not been demonstrated clearly to be transmissible, and if it is, the mode of transmission is not known.(ABSTRACT TRUNCATED AT 400 WORDS)

Allelic variants for complement factors C3, C4, and B in acute necrotizing ulcerative gingivitis.

Impaired immune defense mechanisms and genetic factors appear to play a role in susceptibility to acute necrotizing ulcerative gingivitis (ANUG). Therefore, possible etiological mechanisms might involve genes at the Major Histocompatibility Complex, which include the complement factor loci. We have tested for a possible association between certain complement factor alleles and ANUG using a case-control study design. Specific alleles at complement factors C3 and C4, and properdin factor B (Bf) loci were determined indirectly by high voltage agarose gel electrophoresis in 58 subjects with a history of ANUG and in 58 age-sex-matched healthy controls. The highest relative risk of ANUG, as obtained by conditional logistic regression, for alleles at the C3 locus was 1.9 (90% confidence limits 0.8 to 4.8; p = 0.229) for C3*F-positive individuals. The highest relative risk for alleles at the C4 locus was 2.6 (0.5 to 14.9; p = 0.358) for C4A*3-positive individuals. There was no evidence for an association between Bf allotype and risk of ANUG, with a relative risk of 1.2 for Bf*F- and relative risk of 1.0 for B*S-positive individuals. None of our estimates was statistically significant. We conclude, therefore, that it is unlikely that there is any association between complement factor gene haplotype and susceptibility to ANUG.

A case-control study of plasma ascorbate and acute necrotizing ulcerative gingivitis.

Data from animal studies and from studies of patients with acute necrotizing ulcerative gingivitis (ANUG) have provided suggestive evidence for an association between ascorbate deficiency and disease risk. Further, there is biological plausibility for such an association, due to the role of ascorbate in collagen synthesis and leukocyte function. A case-control study of plasma ascorbate and ANUG was performed on 60 patients with a history of ANUG infection and 60 age-race-sex-matched controls. No cases had had active lesions for at least two months prior to their vitamin assay to avoid any potential reduction of dietary intake of ascorbic acid due to the presence of painful mouth lesions. According to results obtained by use of a modification of the 2,4-dinitrophenylhydrazine method for determination of total plasma ascorbate, the mean and standard error of the mean of plasma ascorbate for all ANUG cases was 0.07 +/- 0.006 mmol/L; the mean for all controls was 0.10 +/- 0.006 mmol/L. Paired differences in plasma ascorbic acid concentrations between cases and controls were significantly different from zero (p less than 0.001). The unadjusted relative risk (RR) of ANUG as obtained by conditional logistic regression for subjects whose plasma ascorbic acid concentration was at or below the median value for controls, relative to subjects with higher values, was 7.3 (90% confidence interval, 3.0 - 17.4; one-sided p value less than 0.001). Patients with a history of ANUG ingested a daily average of 1.2 +/- 0.2 servings of dietary ascorbic acid, as compared with a daily average of 1.9 +/- 0.2 servings for healthy controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Effective management of extremity cancers using cisplatin and etoposide in isolated limb perfusions.

Four cases of extremity cancers received effective management with cisplatin and etoposide via isolated limb perfusion. They demonstrated minimal, if any, soft tissue damage. This result counters the theory that a caustic response is a prerequisite for successful therapy. This characteristic allows for simultaneous surgical resection with regional, isolated limb perfusion of potent cytotoxic agents without increased morbidity from tissue necrosis, a common consequence of previously used drugs. There is no apparent affect on wound healing, even in cases involving extensive, radical operative procedures.

Detection of diabetic retinopathy by optometrists.

Optometrists examined 25 eyes with varying severity of diabetic retinopathy. No history or clinical information was provided to the optometrists who performed fundus examinations on dilated eyes using direct or indirect ophthalmoscopes. Color stereoscopic fundus photographs were independently graded and used as the standard. Optometrists made a correct diagnosis of whether retinopathy was present in 77% of the eyes (95% confidence interval (CI): 73%, 82%). They made a correct diagnosis of the type and degree of diabetic retinopathy in 57% of the eyes (95% CI: 39%, 75%). This diagnosis rate exceeded the rate reported for physician examiners (39%) and equaled that of general ophthalmologists (52%) in the only other similar study. Sensitivity for diagnosis of diabetic retinopathy in eyes of diabetic patients using only ophthalmoscopy was 74% (95% CI: 67%, 81%), while specificity for diagnosis of the absence of retinopathy was 84% (95% CI: 73%, 96%). 100% of these optometrists would have referred the eye with preproliferative retinopathy. 53% would have referred the eye classified as proliferative retinopathy without high risk characteristics, and 79% would have referred the eye with macular edema.
