Statewide survey of the antimicrobial susceptibilities of Haemophilus influenzae producing invasive disease in Tennessee.

Between October 1, 1980, and September 30, 1981, a prospective statewide study of Haemophilus influenzae infections identified 220 culture-proved systemic infections. Of these, 92% were caused by H. influenzae type b. Antimicrobial susceptibility testing of the type b isolates showed that 17% were resistant to ampicillin, but virtually all were susceptible to chloramphenicol, trimethoprim-sulfamethoxazole, cefaclor and rifampin. Ampicillin resistance is common in all parts of Tennessee and chloramphenicol remains the drug of choice for initial therapy of systemic H. influenzae infections.

An outbreak of acute rheumatic fever in Tennessee.

From January, 1987, until July, 1988, a significant increase in newly diagnosed cases of acute rheumatic fever was noted at our hospital. In sharp contrast to the 3 cases seen in 1986, 14 cases were diagnosed in 1987 (a significant increase from 1985 to 1986, P = 0.001). In the first 6 months of 1988 an additional 12 new cases were diagnosed (a further significant increase from 1987, P = 0.02). No further cases were diagnosed between July, 1988, and September, 1989. The major clinical manifestations were carditis in 73%, polyarthritis in 58% and chorea in 31%. In 15 of 26 patients an antecedent illness which included pharyngitis was noted; the remainder of patients were asymptomatic. Group A beta-hemolytic streptococci were isolated from 13 of 19 children cultured. Isolates from two patients with acute rheumatic fever were submitted for M typing: one isolate was mucoid M18/T18; the other isolate was a mucoid nontypable strain. The demographic characteristics of the 26 patients agree with classic descriptions in that patients were more likely to be urban, to come from large families and to have low incomes; racial breakdown of the group mirrored the Tennessee pediatric population. These characteristics stand in contrast to reports of recent outbreaks which describe suburban high income patients. These data suggest that practitioners should be again aware of acute rheumatic fever and that aggressive identification and treatment of streptococcal pharyngitis should continue to be a relevant public health concern.

Contraceptive practices of women attending the Sexually Transmitted Disease Clinic in Nashville, Tennessee.

The decision to be sexually active involves two health risks for women: unwanted pregnancy and sexually transmitted diseases. Use of contraception affects both these risks. Data from the Metropolitan Health Department in Nashville, Tennessee, were examined to determine the effects of particular contraceptive methods on gonococcal infection in women. The results suggest that not only barrier methods but also other types of contraception were associated with protection against gonorrhea in females. The use of contraception was unusually high (87%) among the study population of 1,303 women. Five hundred eighteen (40%) of these clinic attendees were infected with Neisseria gonorrhoea. Infected women tended to be younger than those not infected and were significantly more likely to be black than white and somewhat more likely to be single. Contraceptors tended to be younger and were more likely to be black than were noncontraceptors.

Primary and secondary syphilis in the metropolitan area of Nashville and Davidson County, Tennessee: 1996 to 1998 epidemic described.

BACKGROUND: Metropolitan Nashville, Tennessee experienced a syphilis epidemic from 1996 to 1998. GOAL: This study describes the syphilis epidemic during this period. DESIGN: Descriptive analyses of syphilis surveillance data (1988-1998) were performed, with emphasis on the current epidemic (1996-1998), and were stratified by age, gender, race, and census tracts. RESULTS: Five features were observed regarding the 1996 to 1998 syphilis epidemic: (1) males and females were almost equally affected, with a delay in diagnosis in female patients; (2) the 30-39-year age group was most affected; (3) the 15-19-year age group had the highest percentage increase in incidence; (4) African Americans were the most affected population subgroup; and (5) downtown Nashville and the surrounding areas were most affected. CONCLUSION: Although talk of eradicating syphilis has surfaced nationally, Nashville has continually faced syphilis as a public health problem. During each of the past 3 years (1996-1998), the incidence of syphilis in this community has reached epidemic proportions.

St. Louis encephalitis in Memphis-Shelby County, Tennessee, 1975: epidemiologic aspects of human cases.

An epidemic of St. Louis encephalitis (SLE) occurred in Memphis-Shelby County, Tennessee, in the summer of 1975, as part of an outbreak involving large portions of the Eastern United States. A total of 187 suspected cases were reported, of which 62 were laboratory-confirmed or presumptive SLE. The overall attack rate was 8.1/100,000; rates were higher in lower socioeconomic districts. The case fatality rate was 19.4%. Climatologic data and related factors favoring the occurrence of this outbreak are discussed.

Epidemiology of a thermonuclear bomb-burst over Nashville, Tennessee: a theoretic study.

A thermonuclear bomb explosion over any city in the world would have a devastating effect on the population and environment. For those who survive, with or without injuries, life would become primitive with little or no uncontaminated food or water, and with inadequate housing, fuel, and medical care, resulting in a breakdown of family and interpersonal relationships. This theoretic study of the potential outcome of a thermonuclear bomb-burst over Nashville, Tennessee, discusses epidemiologically the wide range of medical and psychologic effects from the direct trauma of blast and fire, widespread epidemics of otherwise controlled disease, long-term chronic illness, genetic damage, and catastrophic environmental havoc.

American Cancer Society's Breast Cancer Detection Awareness Program: the 1988 middle Tennessee experience.

In an effort to augment public awareness of the benefits of screening mammography and to encourage the use of screening mammograms, the Tennessee Division of the American Cancer Society initiated the Breast Cancer Detection Awareness Program in March 1988. As a result of the initiative, 3,473 women telephoned for information, and 3,123 were found to be eligible for a screening mammogram. Of the 2,248 mammograms actually obtained, 1,764 (78%) were interpreted as normal, whereas 484 (22%) were classified as abnormal. Of the 484 women with abnormal mammograms, 277 (57%) were advised to have follow-up mammograms and 57 (12%) had excisional biopsy. The 55 biopsies reported showed benign changes in 83.6% and malignancy in 16.4%. Thus, nine malignancies were discovered from 2,248 screening mammograms (four malignancies per 1,000 mammograms). No malignancies were found in women between 35 and 39 years old.

Increased incidence of syphilis in Tennessee during the 1980s: challenges for a new decade.

Although recent increases in the incidence of syphilis are well known to public health officials, the general medical community is less well informed regarding the dramatic rise in cases. We present trend data from Nashville and Tennessee over the past decade. These statistics emphasize specific factors, such as drug abuse, that contribute to new difficulties in controlling this sexually transmitted disease.

Appearance of drug-resistant tuberculosis in rural Tennessee.

Drug-resistant tuberculosis (DRTB) is a growing national health concern in both urban populations and rural areas and is exacerbated by the growing epidemic of human immunodeficiency virus (HIV) infection. Between 1989 and 1992, 7 cases of DRTB (5 with multidrug-resistance) were diagnosed in an eight-county region of East Tennessee. During 1990 and 1991 alone, 5 of 100 patients with tuberculosis had drug-resistant strains (5%). All 7 patients with DRTB had 100% resistance to isoniazid; 5 also had resistance to streptomycin, 2 to rifampin, and 1 to pyrazinamide and ethambutol. All patients were white, U.S.-born, and without evidence of HIV infection. Contact investigation revealed that more contacts of patients with DRTB (13 of 74, 18%) were infected than were contacts of patients with drug-sensitive tuberculosis (46 of 290, 16%). Our study demonstrates that DRTB is not confined to geographically distinct areas, but may be a subtle and easily missed diagnosis in presumably low-risk rural populations.

Unusual case of pyopneumothorax in Tennessee.

Rupture of a coccidioidal pulmonary cavity with subsequent pyopneumothorax is a rare clinical event, even in areas endemic for coccidioidomycosis. Our encounter with a patient diagnosed with this condition in northeast Tennessee serves notice to clinicians that coccidioidomycosis is indeed a traveling fungal disease, and practitioners must be alert to common and uncommon manifestations of infection associated with this fungus. A literature review pertaining to coccidioidal pyopneumothorax revealed that patients usually present with a recent onset of chest pain. Serologic testing and pleural fluid culture are highly useful, and management includes surgical intervention with or without antifungal therapy.

Proposed methods and endpoints for defining and assessing adverse environmental impact (AEI) on fish communities/populations in Tennessee River reservoirs.

Two multimetric indices have been developed to help address fish community (reservoir fish assemblage index [RFAI]) and individual population quality (sport fishing index [SFI]) in Tennessee River reservoirs. The RFAI, with characteristics similar to the index of biotic integrity (IBI) used in stream fish community determinations, was developed to monitor the existing condition of resident fish communities. The index, which incorporates standardized electrofishing of littoral areas and experimental gill netting for limnetic bottom-dwelling species, has been used to determine residential fish community response to various anthropogenic impacts in southeastern reservoirs. The SFI is a multimetric index designed to address the quality of the fishery for individual resident sport fish species in a particular lake or reservoir[4]. The SFI incorporates measures of fish population aspects and angler catch and pressure estimates. This paper proposes 70% of the maximum RFAI score and 10% above the average SFI score for individual species as "screening" endpoints for balanced indigenous populations (BIP) or adverse environmental impact (AEI). Endpoints for these indices indicate: (1) communities/populations are obviously balanced indigenous populations (BIP) indicating no adverse environmental impact (AEI), or are "screened out"; (2) communities/populations are considered to be potentially impacted; and (3) where the resident fish community/population should be considered adversely impacted. Suggestions are also made concerning how examination of individual metric scores can help determine the source or cause of the impact.

Prenatal exposure to prescribed drugs in Tennessee Medicaid, 1983-1988.

This report describes the prenatal exposure histories of 107,804 women to prescribed drugs other than vitamins, iron and other minerals. The data were obtained from Tennessee Medicaid pharmacy files linked to birth and fetal death certificates for 1983-1988. The utility of these data to other investigators in predicting power or estimating sample size for studies of drug exposure in pregnancy associated with adverse birth outcomes is discussed.

The role of Tennessee antigen in the diagnosis of gastrointestinal malignancy.

Tennessee antigen (TAG) is a glycoprotein which has been extracted from adenocarcinoma of the colon. It is one of the numerous tumour associated antigens which has been developed and there is evidence that it differs considerably from carcino-embryonic antigen (CEA) preparations. A commercial kit using a haemagglutination inhibition assay is available and its ability to discriminate between benign and malignant conditions of the gastrointestinal tract has been studied, using 7.7 units/ml as the upper limit of normal. With upper gastrointestinal disease, discrimination is comparable to that achieved with TAG by other workers and also to that achieved with CEA. For gastric carcinoma TAG has a sensitivity of 71% and a specificity of 77%. With lower gastrointestinal tract disease discrimination was poor, TAG having a sensitivity of 76% but a specificity of 44% for colorectal carcinoma. Discrimination between pancreatic carcinoma and chronic pancreatitis was poor, TAG having a sensitivity of 100% for carcinoma and a specificity of 22%.

Moral considerations in body donation for scientific research: a unique look at the University of Tennessee's anthropological research facility.

This paper discusses keys to the moral procurement, treatment and disposition of remains used for scientific research, specifically those donated to the University of Tennessee's Anthropological Research Facility (ARF). The ARF is an outdoor laboratory dedicated to better understanding the fate of human remains in forensic contexts, and focuses its research on decomposition, time since death estimates, body location and recovery techniques, and skeletal analysis. Historically, many donations were unclaimed bodies received from medical examiners (although it will be shown that this trend is changing), and it has been argued that the use of the unclaimed bodies for medical or scientific purposes is a violation of autonomy since no consent was given by the individual. It is argued here, however, that the domain of autonomous choice extends to one's own corpse only insofar as expressed wishes are made known prior to one's death, and that in the absence of expressed intent toward final disposition, it is acceptable for institutions to receive donations from medical examiners or family members. This paper also discusses other philosophical issues related to donation, consent and autonomy, and the forensic benefits of research conducted at the Anthropological Research Facility.

Dimensionality of the perceived self: the Tennessee Self Concept Scale.

The 12 indices of self-perception in the Tennessee Self Concept Scale, together with the Eysenck Personality Inventory, were factor analysed using data obtained from psychiatric day-care patients (n = 131). Separate item- and scale-level factor analyses revealed that: (1) the five external and three internal domains of self-concept, hypothesized as distinct, may be accurately viewed as lying in one-dimensional space; (2) the conflict, variability and distribution scores are unrelated to subtype of self-esteem; (3) extraversion and neuroticism form a bipolar factor that is orthogonal to self-concept; and (4) the emergence of 30 item-factors with a 30 per cent factorial overlap implies a good deal of spuriously shared variance, low inter-scale homogeneity and sizable redundancy in the TSCS scales. Owing to these results, the construct and factorial validity of the TSCS is seriously questioned. It is suggested that future researchers develop more sensitive, treatment-oriented (or idiographic) measures to compare man's less conspicuous and more private 'self-image feelings and cognitions' against his public self-disclosure in the interests of facilitating more rapid behavioural change.

Antimicrobial susceptibility patterns and staphylococcal cassette chromosome mec types of, as well as Panton-Valentine leukocidin occurrence among, methicillin-resistant Staphylococcus aureus isolates from children and adults in middle Tennessee.

Antimicrobial susceptibility patterns, Panton-Valentine leukocidin (PVL) occurrence, and staphylococcal cassette chromosome mec (SCCmec) types in methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from children and adults at Vanderbilt University Medical Center during a 12-month period were evaluated. A total of 1,315 MRSA isolates were collected, of which 748 (36.7%) were recovered from children. Among all isolates, 448 (34.1%) were SCCmec-II, and 847 (64.4%) were SCCmec-IV. More SCCmec-IV isolates were recovered from children than SCCmec-II isolates (424 [50.1%] versus 50 [11.2%]; odds ration [OR]=7.98; P<0.000001). The PVL gene was detected in 93.6% of SCCmec-IV isolates, in contrast to 0.2% in SCCmec-II isolates. Within SCCmec-IV isolates, a statistically higher PVL occurrence was noticed in children (98.1%) than in adults (89.1%) (OR=6.34; P<0.000001). Overall, SCCmec-II strains showed greater resistance than SCCmec-IV strains to clindamycin, erythromycin, levofloxacin, gentamicin, rifampin, minocycline, and trimethoprim-sulfamethoxazole. Both SCCmec-II and SCCmec-IV strains recovered from adults were more resistant to these antibiotics than those recovered from children. SCCmec-II strains were predominantly recovered from the respiratory tract, whereas SCCmec-IV strains were predominantly recovered from skin, soft tissue, abscesses, and surgical wounds. These data indicate that SCCmec-IV MRSA isolates frequently infect children in middle Tennessee and are likely to harbor the PVL gene.
