The use and abuse of wound care materials in the treatment of diabetic ulcerations.
With the ever-increasing availability of wound care materials for use in diabetic foot ulcerations, a thorough understanding of the indications and applications of these materials is important for wound-management success. The coupling of a lack of understanding of the interaction of wound care materials and the dynamic nature of wound-healing physiology may lead to a protracted healing course that may constitute an abuse of an otherwise useful adjunct to wound healing protocols. This article provides an overview of wound care products, their indications, and possible complications of inappropriate use.

A case-control study of hematopoietic and lymphoid neoplasms: the role of work in the chemical industry.
The present case-control study was conducted in an effort to determine if work in the chemical industry is related to excesses of certain hematopoietic and lymphoid neoplasms. Cases who died from non-Hodgkin's lymphoma, multiple myeloma, and leukemia were matched by race, gender, age, year of death, and county of residence to controls who died from cardiovascular disease. A total of 618 (309 matched pairs) white male residents of Kanawha County, WV, aged 23-96, who had died between 1965 and 1990 were identified. Conditional logistic regression was conducted and yielded an association between chemical industry work and death due to non-Hodgkin's lymphoma, multiple myeloma, and lymphoid leukemia among subjects who died at age < 65. These results are consistent with the findings of previous studies linking work in chemical manufacturing to hematopoietic and lymphoid neoplasms, and indicate that the excesses may be related to the occupational exposures in men who died at younger ages.

Cellulitis secondary to web space dermatophytosis.
Cellulitis occurring in the lower extremity is encountered frequently and results from a breach of the skin and inoculation of opportunistic bacteria. It has been shown that when web space dermatophytosis is present, changes may occur in normal skin morphology and bacterial flora that can result in severe infection. Knowledge of the pathophysiology of interdigital dermatophytosis allows the clinician to choose the most appropriate empiric antibiotic therapy when treating a secondarily caused cellulitis of the lower extremity.

Evaluation and management of the interdigital corn: a literature review.
Interdigital corns or soft corns are the accumulation of spongy, hyperkeratotic, circumscribed tissue between opposing surfaces of adjacent digits of the foot. The authors discuss the incidence, causes, locations, and treatment of these interdigital corns.

Trends in cancer mortality in Kanawha County, West Virginia, 1950-1984.
There has been much concern recently about possible adverse health effects related to exposure to toxic chemicals among residents of Kanawha County in southern West Virginia. An epidemiological study of trends in cancer mortality from 1950-1984 among the general population of Kanawha County in southern West Virginia was mounted. Cabell County, West Virginia was chosen to be a comparison county for Kanawha in addition to West Virginia and the total United States. The cancer mortality rates for white males and females were calculated using NCHS mortality data and Census Bureau population data available on the Mortality and Population Data System (MPDS) at the University of Pittsburgh. Mortality rates for cancer in Kanawha and Cabell Counties were evaluated over the time period 1950-1984 with an age-period-cohort (APC) analysis. In this analysis, poisson regression models were fit using the statistical program GLIM (Generalized Linear Models) to determine the separate effects of age, period of death, and birth cohort on the specific cancers of interest (lung, liver, bladder, CNS, leukemia, lympho-reticulosarcoma, all cancers). There were no significant county differences for cancer death rates between Kanawha and Cabell Counties except for leukemia among white males [O.R. = 1.27, 95% (C.I. = 1.03-1.6)], and for lympho-reticulosarcoma [O.R. = 1.66(1.24-2.07)], suggesting a possible occupational exposure. For leukemia, aleukemia, the effect observed seems to have declined. In contrast, the elevation of lympho-reticulosarcoma rates has remained in recent years (1970-1984).

Noise-induced hearing loss: a possible marker for high blood pressure in older noise-exposed populations.
The present study assessed the relationships among occupational noise exposure, noise-induced hearing loss, and high blood pressure. The study population consisted of 245 retired metal assembly workers from Pittsburgh aged 56 to 68 with chronic noise exposure of 30 or more years at greater than or equal to 89 dBA. Results of the audiometric testing indicated 52% of the younger workers (ages 56 to 63) have severe noise-induced hearing loss (greater than or equal to 65 dBA loss at 3, 4, or 6 kHz) and 67% of older workers (ages 64 to 68). Body mass index and alcohol intake were significantly related to systolic and diastolic blood pressure. Among older men, there was a marginally significant increased prevalence of high blood pressure (greater than or equal to 90 mm diastolic or taking blood pressure medicine) among those with severe noise-induced hearing loss (P = .05). Moreover, another measure of hearing loss at high frequencies, speech discrimination score in noise (measured in the better ear), referred to as the W-22 MAX score, was also found to be related to the prevalence of high blood pressure in the older (64 to 68) age group (P less than .05). Multiple regression analysis revealed W-22 MAX and severe noise-induced hearing loss were independent predictors of hypertension in the older, but not in the younger group of retired workers.

A randomized walking trial in postmenopausal women: effects on physical activity and health 10 years later.
BACKGROUND: It is important to determine if permanent lifestyle changes may result from physical activity interventions and whether health may be affected by these changes. OBJECTIVE: To conduct a 10-year follow-up of physical activity and self-reported health status in participants of a randomized clinical trial of walking intervention. METHODS: Of the original 229 volunteer postmenopausal women who participated in the original clinical trial, 196 (N = 96 intervention and 100 controls) completed the 10-year follow-up telephone interview. The interview protocol included questions on self-reported walking for exercise and purposes other than exercise, the Paffenbarger sport and exercise index, functional status, and various chronic diseases and conditions. RESULTS: The median values for both usual walking for exercise and total walking were significantly higher for walkers compared with controls (for both, P = .01), with median differences of 706 and 420 kcal/wk, respectively. After excluding women who reported heart disease during the original trial, 2 women in the walking group (2%) and 11 women in the control group (12%) reported physician-diagnosed heart disease over the last 10 years (P = .07). There were also fewer hospitalizations, surgeries, and falls among women in the walking group, although these differences were not statistically significant (P>.05). CONCLUSIONS: Although limited by self-report, this study may be the first to demonstrate long-term exercise compliance to a randomized control trial in older women and to suggest that health benefits may have ensued as a result of these increased activity levels.
