A retrospective review of the cases of congestive heart failure admitted to Holberton Hospital in Antigua in 1995 and 1996 was undertaken. Two hundred and ninety-three (293) patients were identified by International Statistical Classification of Diseases, 10th revision (ICD-10) coding as having congestive cardiac failure in the period but only 138 charts were either available or fitted the definition of congestive cardiac failure and these provided the basis for this analysis. The average age of patients admitted for congestive cardiac failure was 69 years (range: 5 months to 99 years), and 63% were female. the aetiology of congestive cardiac failure was hypertension (41%), ischaemia (33%), valvular (12%), alcohol related (2%), idiopathic (5%) and mixed (7%). Treatment included diuretics (95%), angiotensin converting enzyme inhibitors (78%), digoxin (75%), nitrates (34%), calcium channel blockers (25%), other vasodilators (7%) and antiarrhythmics (5%). Of those with congestive heart failure, diabetes was present in 38%, atrial fibrillation in 19%, renal insufficiency in 17%, elevated cholesterol in 11%, obesity in 9% and tobacco use in 7%. The in-hospital mortality in the 2-year period was 17.4% (females 15%, males 22%, 11% < 65 years, 20% > 65 years, 14% for those with 1 to 3 admissions and 83% for those with > 3 admissions, 19% for those with atrial fibrillation and 16% for those without). The prevalence of congestive cardiac failure utilizing the data analysed in this study (138 patients) was 0.21% of the population of the island state but based on the discharge diagnosis using ICD-10 coding it was 0.5%; it was 1% in the 40 to 65-year-age group and 4% in those > 65 years of age. The patients in this study represented only those with New York Heart Association (NYHA) classes III and IV, hence the true prevalence would be higher than recorded here. Congestive cardiac failure is emerging as a significant health problem in Antigua and Barbuda.

This paper aims at studying the development and the risk factors for stroke prospectively during a 6-year follow-up in the Turku Elderly Study, Turku, Finland. The study cohort consisted of 1032 people aged 70 years at baseline. The stroke events (ICD-9 codes 430-434) were identified by computer linkage from the hospital discharge and death registers, and from a follow-up questionnaire. During the 6 years of follow-up, 71 patients (6.9%) suffered a stroke. Previous stroke (RR 5.82), history of transient ischemic attack (RR 4.14), diabetes mellitus (RR 2.50), poorly controlled hypertension (RR 2.42), smoking (RR 1.94) and male sex (RR 1.65) were independent risk factors for stroke. Atrial fibrillation, cardiac failure and previous myocardial infarction did not appear to be significant independent predictors of stroke in the elderly. The risk of stroke in the elderly population appears to be strongly related to the concomitant clinical disease, and this should be remembered when identifying persons at increased risk of stroke. Poorly controlled hypertension was associated with an increased risk of stroke. Thus, achieving a good control of blood pressure in elderly hypertensives receiving treatment has the potential to prevent strokes.

The rapidly rising prevalence of obesity, worldwide, has prompted re-evaluations of the definitions and diagnostic criteria, and of the extent of the burden it contributes to health care services. Although categorized arbitrarily for epidemiological purposes according to BMI > 25 kg/m2 ('overweight') and BMI > 30 kg/m2 ('obese'), the disease itself (ICD code E.66) is the process of excess fat accumulation. It leads to multiple organ-specific pathological consequences, particularly if there is a tendency to intra-abdominal fat accumulation. The simplest field method to identify obesity and risk of medical problems is the waist circumference, and this method has found a special role in health promotion. Risks begin with waist > 80 cm (women) or > 94 cm (men). As a broad generalization, obesity produces few symptoms below the age of 40 years, but then several symptoms often develop; tiredness, breathlessness, back pain, arthritis, sweatiness, poor sleeping, depression and menstrual disorders all being common. The symptoms are often attributed to diseases in other body systems. Metabolic diseases like diabetes, hyperlipidaemia and, hypertension develop later, but the mean BMI at diagnosis of diabetes is 28 kg/m2. Ultimately, obesity increases the likelihood of myocardial infarction, stroke and several major cancers, but its biggest impact on health, especially in the elderly, is probably the multiplicity of effects on other body systems. The greatest challenge for public health is to develop effective preventive measures, recognizing that BMI > 25 kg/m2 before the age of 20 years is a very strong predictor of obesity and ill health in adulthood.

PURPOSE: The objective of this retrospective analysis was to compare secular changes in the rate of emergency room admissions (per 100,000) for selected acknowledged preventable cardiovascular conditions among African Americans (AA) men and women aged >/=21 from 1991-1998, and rate of change for Caucasian (Cau), Hispanic (Hisp), and Asian (Asi) men and women aged >/=21; conditions included angina, congestive heart failure (CHF), diabetes, and hypertension.METHODS: Results are derived from calendar-year California hospital data based on a selection of specified ICD-9 codes that correspond to the principal diagnosis for admission. The combined study sample size included a total of 21,016 individuals who were admitted to a hospital via the ER. Separate standardized and age-adjusted Poisson regression models were employed for each condition to assess race and time main effects and race x time interaction terms (P </= 0.01). Age and payer-source were entered as covariates to control for confounding effects. Men and women were analyzed separately.RESULTS: Mean overall rates of ER admission due to angina were significantly lower among AA men compared to Cau men (17.8 vs 18.2); however, rates were higher among Hisp and Asi men (6.03 and 7.1, respectively). Rates for CHF were higher among AA men compared to Cau, Hisp, and Asi men (23.7 vs, 11.0, 3.7, 4.8, respectively); similar results were observed for diabetes (8.6 vs 2.7, 2.3, 1.2, respectively) and hypertension (5.1 vs, 1.6, 0.9, 1.5, respectively). Differentials in 1991 resulted in widening disparities overtime for each condition. For women, mean overall rates due to angina were significantly higher among AA women compared Cau, Hisp, and Asi women (17.0 vs 13.5, 5.7, 5.7, respectively). Similar patterns were observed for CHF (23.1 vs, 11.0, 3.7, 4.8, respectively), diabetes (6.4 vs 2.0, 1.8, 1.1, respectively) and hypertension (5.8 vs 1.9, 1.1, 1.5), respectively). As observed among AA men, differentials in 1991 resulted in widening disparity overtime.CONCLUSIONS: Findings reveal higher rates of ER admissions for preventable cardiovascular conditions among AA men and women during the 1990s with evidence of widening health status disparities into the new millennium.

Studies which evaluate the psychosocial development and integration of adult female congenital adrenal hyperplasia (CAH) patients are rare but show that patients with the salt wasting form are significantly more virilized and more frequently single and childless. Major complaints are irregular menstruation, hirsutism, acne, obesity, deep voice, and cushingoid features. Surprisingly, a higher prevalence of psychosomatic disorders has not yet been described. Since anorexia nervosa (AN) has not yet been described in patients with CAH, we here report 4 cases of female CAH patients who developed AN during adolescence. Diagnosis of CAH was made between the age of 10 days and 3 years. Three patients suffer from the simple-virilizing form of CAH, one patient has a mild salt wasting CAH. Genital malformation varied from Prader stage II to IV. All 4 patients were compound heterozygotes for mutations/deletions of the CYP21B gene. Control of substitution therapy consisting of hydrocortisone and fluorocortisone was good. AN developed at ages 12, 13, 17, and 21 years (ICD 10 criteria for AN are BMI below 17.5 kg/m2, deliberate weight loss, body image disturbance, and primary or secondary amenorrhoea). Diagnosis of AN was established by psychiatrists and/or psychologists. All four patients showed an impressive and deliberate weight loss between 13 and 20 kg within 6 months, had primary or secondary amenorrhoea, and presented with BMI between 13 and 17.9 kg/m2. All patients received psychological treatment and recovered. However, one patient had a severe relapse of AN. Two patients are now married and one has a healthy son. These cases demonstrate that the diagnosis of CAH is compatible with the development of AN and illustrate the importance of providing treatment for CAH patients that encompasses not only medical but also psychological and social care.

The author's aim is to aid primary care physicians and obstetrician-gynecologists in correctly diagnosing and treating premenstrual dysphoric disorder (PMDD). The symptoms fluctuate markedly, but their timing is key. PMDD patients experience symptoms only during the luteal phase and will have a symptom-free interval after the menstrual flow and before ovulation. The author discusses self-report instruments, which are valuable tools for diagnosis when combined with the ICD-10 criteria for premenstrual syndrome (PMS) or the DSM-IV criteria for PMDD and the ruling out of medical and psychiatric conditions, such as diabetes, hypothyroidism, major depression, and dysthymia, that cause similar symptoms. Treatment strategies ranging from nonpharmacologic approaches such as dietary modification and aerobic exercise to pharmacologic interventions such as antidepressants, anxiolytics, and agents to suppress ovulation are examined.

An association between elevated white blood cell (WBC) count and coronary heart disease (CHD) mortality has been previously observed. However, the relationship between WBC count and CHD mortality independent of cigarette smoking and the possible interaction between WBC count and smoking remains unclear. We examined the association between WBC count and CHD mortality with Cox regression analyses of data from 8914 adults, aged 30-75, in the NHANES II Mortality Study (1976-1992). Covariates included age, sex, race, education, physical activity, smoking status, hypertensive status, total serum cholesterol, body mass index, hematocrit, and history of cardiovascular disease, stroke, and diabetes. During 17 follow-up years, there were 548 deaths from CHD (ICD-9 410-414) and 782 deaths from diseases of the heart (ICD-9 390-398, 402, 404, 410-414, 415-417, 420-429). Mean WBC count (x10(9) cells/L) was greater among persons who died from CHD (7.6 vs 7.2, P <.001). Compared to persons with a WBC count <6.1, persons with a WBC count > 7.6 were at increased risk of death from CHD (relative risk = 1.4, 95% confidence interval = 1.1-1.8) after adjustment for smoking status and other CVD risk factors. Similar results were observed among nonsmokers (RR = 1.4, 95% CI = 0.9-2.0). These results suggest that higher WBC counts are a predictor of CHD mortality independent of the effects of smoking and other traditional CVD risk factors, which may indicate a role for inflammation in the pathogenesis of CHD. Additional studies are needed to determine whether interventions to decrease inflammation can reduce the risk for CHD associated with elevated WBC.

This case report highlights a previously unreported cause of T wave oversensing in a patient with an ICD and recent onset diabetes. Consistent T wave oversensing was observed at elevated serum glucose levels and this finding was reproduced with a glucose challenge. No T wave oversensing was seen during treatment of hyperglycemia. Alterations in serum chemistry may account for intermittent T wave oversensing in patients with ICDs.

Based on the nationwide registration of the total hip arthroplasties (THAs) in Finland since 1980, a cohort of 24,638 patients with primary THA was gathered and followed for causes of death until December 31, 1996. The causes of death were divided into 20 main categories according to the classification of diseases ICD-10. The number of person-years was 153,410, and the mean length of follow-up of a person was 6.2 years. During the follow-up, 4,626 patients died; the expected number was 6,746. The standardized mortality ratio (SMR) was 0.69 (95% confidence interval; 0.67-0.70), without any difference between men and women. The total risk increased during the follow-up, with the highest being 0.84 (95% confidence interval, 0.81-0.87). Among the ICD categories, there were significantly low SMRs for cancers (0.54), accidents (0.74), cardiovascular diseases (0.70), and respiratory diseases (0.46). Among the diseases, there was a constant and significant decline of the SMR for dementia and Alzheimer's disease (0.50), diabetes (0.40), myocardial infarction (0.73), hypertension (0.68), other ischemic diseases (0.70), other heart diseases (0.57), and cerebrovascular diseases (0.70). The explanation for the decreased SMRs seems to be attributed to factors other than the THA per se, such as preoperative patient selection, more active lifestyle after THA, and possibly the use of anti-inflammatory drugs.

The aim of this study was to guide service provision for prevention of diabetic foot complications through the analysis of hospital separation data for those with diabetes in central Australia. We reviewed the hospital separation data for central Australia from 1992 to 1997 for adults known to be diabetic and those with diabetic foot complications. Foot complications were identified from International Classification of Diseases-9th Revision (ICD-9) codes. Additionally, we assessed the proportion of cases with diabetic foot, identified by ICD-9 coding and confirmed by record review, that were identified by Australian National-Diagnostic Related Group-Version 3 (AN-DRG-3) coding. Separations with diabetes doubled from 352 in 1992 to 796 in 1997. This represents an increase from 1232 to 2521 separations per 100,000 people over 15 years of age. Separations with foot complications increased threefold from 28 in 1992 to 90 in 1997, a rate increase from 98 to 285 per 100,000 people over 15 years of age. The proportion of diabetes separations that had foot complications remained around 10% during the 6 year period. Aboriginal people made up 89% of the individuals with foot complications and 91% of separations for diabetic foot. Foot complications were predominantly of the more acute type (90%), amenable to early intervention. The AN-DRG-3 code for diabetic foot identified only 59% (37/63 in 1997) of the separations identified by the ICD-9 codes, and admitted primarily for foot complications in Alice Springs Hospital. The known burden of hospital care for diabetes and diabetic foot complications has increased markedly in recent years. A combination of changes in prevalence, primary care utilisation, detection, hospital access or re-admission rates may underlie the observed increases. As it is very unlikely that diabetes or diabetic foot complications are being over diagnosed, or that the hospitals are over utilised, this analysis shows there is an increasingly apparent need for improved prevention of diabetic foot complications. Therefore primary health care systems should ensure that they implement evidence-based care for preventing foot complications among people with diabetes.
