Prior medical conditions and medication use and risk of non-Hodgkin lymphoma in Connecticut United States women.

OBJECTIVE: To further investigate the role of prior medical conditions and medication use in the etiology of non-Hodgkin lymphoma (NHL), we analyzed the data from a population-based case-control study of NHL in Connecticut women. METHODS: A total of 601 histologically confirmed incident cases of NHL and 717 population-based controls were included in this study. In-person interviews were administered using standardized, structured questionnaires to collect information on medical conditions and medication use. RESULTS: An increased risk was found among women who had a history of autoimmune disorders (such as rheumatoid arthritis, lupus erythematosus, Sjogren's syndrome, and multiple sclerosis), anemia, eczema, or psoriasis. An increased risk was also observed among women who had used steroidal anti-inflammatory drugs and tranquilizers. A reduced risk was found for women who had scarlet fever or who had used estrogen replacement therapy, aspirin, medications for non-insulin dependent diabetes, HMG-CoA reductase inhibitors, or beta-adrenergic blocking agents. Risk associated with past medical history appeared to vary based on NHL subtypes, but the results were based on small number of exposed subjects. CONCLUSION: A relationship between certain prior medical conditions and medication use and risk of NHL was observed in this study. Further studies are warranted to confirm our findings.

"A grief observed": the experience of HIV-related illness and death among women in a clinic-based sample in New Haven, Connecticut.

This study examined how women in a clinic-based sample in New Haven, Connecticut, (N = 168), have been affected by the AIDS epidemic. The aims of this study were to (a) document the proportion of women who knew individuals who were HIV positive, who were symptomatic with AIDS, or who had died from AIDS; (b) compare the demographics of women who knew someone infected with HIV with those of women who did not know anyone infected with HIV; and (c) examine prospectively the effects of the number of AIDS-related losses on women's mental health. Many women have been deeply affected by the AIDS epidemic: Nearly 3/4 of the women in this study knew at least 1 person who had died of AIDS. Women who experienced multiple AIDS-related losses over the course of the study were significantly more anxious than those who experienced no loss or 1 loss. Implications for clinical interventions are discussed.

Patterns of blood use in Connecticut.

Blood use patterns were studied in a setting essentially free of the constraints of shortage, high-cost, nonreplacement penalties, and high hepatitis risk. Connecticut's hospitals used an average of 0.299 unit of blood per patient discharge in 1978. Interhospital variation was great, with large hospitals using more blood per discharge. The percentages of blood ordered by individual hospitals as red blood cells ranged from 38.9 to 96.2 per cent. Frozen red blood cells were ordered in greater proportion by large hospitals. Relative plasma use was greater in large hospitals, ranging from 0.003 to 0.232 unit per unit of blood. Hospital outdating ranged from 0.1 to 21.3 per cent, with large hospitals outdating proportionately less. Such striking variations suggest that habits and personal preferences may determine the pattern of a hospital's blood use, and, therefore, the costs of blood provision. Statewide from 1971 to 1978, red blood cell ordering increased from 13.8 to 63 per cent of total blood order. Plasma use has increased from 0.025 to 0.130 unit per unit of blood. Blood use per patient discharge has also increased, but more slowly.

Late mandibular fracture after third molar surgery: a survey of Connecticut oral and maxillofacial surgeons.

PURPOSE: This study investigated the incidence and causative factors involved in late mandibular fractures after third molar surgery. MATERIALS AND METHODS: A questionnaire was sent to 106 oral and maxillofacial surgeons in Connecticut, asking them about their experience with late fractures over a 10-year period. RESULTS: A 79% response indicated 28 fractures occurring in 611,000 extractions, for an incidence of 0.0046%. The cause was found to be multifactorial and included age, gender, type of impaction, preexisting infection, and failure to maintain a soft diet in the postoperative period. Most fractures occurred between the 1st and 21st days postoperatively. Three of the fractures resulted in malpractice litigation. CONCLUSION: Men over the age of 25 years should be specifically informed about the risk of late mandible fracture after third molar surgery. This group of patients should be educated about the quality and duration of a soft diet.

Lactation and breast cancer risk: a case-control study in Connecticut.

In this report, we examined the relationship between lactation and breast cancer risk, in a case-control study of breast cancer, conducted in Connecticut between 1994 and 1998. Included were 608 incident breast cancer cases and 609 age frequency matched controls, aged 30-80 years old. Cases and controls were interviewed by trained study interviewers, using a standardized, structured questionnaire, to obtain information on lactation and other major risk factors. Parous women who reported ever lactation had a borderline significantly reduced risk of breast cancer (OR = 0.83, 95% CI, 0.63-1.09). An OR of 0.53 (95% CI, 0.27-1.04) was observed in those having breastfed more than 3 children compared to those who never lactated. Women having breastfed their first child for more than 13 months had an OR of 0.47 (95% CI, 0.23-0.94) compared to those who never breastfed. Lifetime duration of lactation also showed a risk reduction while none of the ORs were statistically significant. Further stratification by menopausal status showed a risk reduction related to lactation for both pre- and postmenopausal women, while the relationship is less consistent for the latter. These results support an inverse association between breastfeeding and breast cancer risk.

The prevalence of cancer. Estimates based on the Connecticut Tumor Registry.

Cancer incidence and mortality do not fully reflect the effect of cancer. To estimate the number of persons alive who have a history of cancer, we derived prevalence rates based on data from the Connecticut Tumor Registry. We did not attempt to distinguish between people who had been cured of cancer and those who still had the disease. In 1982 the age-adjusted prevalence rates of cancer among males and females were 1,789 and 2,222, respectively, per 100,000. Age-specific prevalence rates were highest among the elderly; 12 percent of men and 11 percent of women over 70 had previously been given a diagnosis of cancer. Breast cancer in females and prostate cancer in males were the two most prevalent malignant diseases. We estimate that about 5 million persons alive in the United States today have at one time received a diagnosis of cancer.

Cat scratch disease in Connecticut. Epidemiology, risk factors, and evaluation of a new diagnostic test.

BACKGROUND: Although cat scratch disease is commonly diagnosed in patients who have unexplained regional lymphadenopathy after encounters with cats, its epidemiology and the risk factors for disease are not clearly defined, and there is no generally accepted diagnostic test. METHODS: We conducted a physician survey to identify cases of cat scratch disease occurring over a 13-month period in cat owners in Connecticut. We interviewed both the patients (or their parents) and controls matched for age who owned cats. Serum from the patients was tested for antibodies to Rochalimaea henselae with a new, indirect fluorescent-antibody test. RESULTS: We identified 60 patients with cat scratch disease and 56 age-matched subjects. Patients were more likely than controls to have at least one pet kitten 12 months old or younger (odds ratio, 15), to have been scratched or bitten by a kitten (odds ratio, 27), and to have had at least one kitten with fleas (odds ratio, 29). A conditional logistic-regression analysis found that in kitten-owning households, patients were more likely than controls to have been scratched or bitten by a cat or kitten (odds ratio, 12.4; 95 percent confidence interval, 1.0 to 150). Of 45 patients, 38 had serum samples with titers of 1:64 or higher for antibody to R. henselae, as compared with 4 of 112 samples from controls (P < 0.001). The positive predictive value of the serologic test was 91 percent. Of 48 serum samples from patients' cats, 39 were positive for antibodies to R. henselae, as compared with positive samples from 11 of 29 control cats (P < 0.001). CONCLUSIONS: Cat scratch disease is strongly associated with owning a kitten, and fleas may be involved in its transmission. The serologic test for rochalimaea may be useful diagnostically, and our results suggest an etiologic role for this genus.

Lyme disease in children in southeastern Connecticut. Pediatric Lyme Disease Study Group.

BACKGROUND: Although the incidence of Lyme disease is highest in children, there are few prospective data on the clinical manifestations and outcomes in children. METHODS: We conducted a prospective, longitudinal, community-based cohort study of children with newly diagnosed Lyme disease in an area of Connecticut in which the disease is highly endemic. We obtained clinical and demographic information and performed serial antibody tests and follow-up evaluations. RESULTS: Over a period of 20 months, 201 consecutive patients were enrolled; their median age was 7 years (range, 1 to 21). The initial clinical manifestations of Lyme disease were a single erythema migrans lesion in 66 percent, multiple erythema migrans lesions in 23 percent, arthritis in 6 percent, facial-nerve palsy in 3 percent, aseptic meningitis in 2 percent, and carditis in 0.5 percent. At presentation, 37 percent of the patients with a single erythema migrans lesion and 89 percent of those with multiple erythema migrans lesions had antibodies against Borrelia burgdorferi. All but 3 of the 201 patients were treated for two to four weeks with conventional antimicrobial therapy, which was administered orally in 96 percent. All had prompt clinical responses. After four weeks, 94 percent were completely asymptomatic (including the two patients whose parents had refused to allow antimicrobial treatment). At follow-up a mean of 25.4 months later, none of the patients had evidence of either chronic or recurrent Lyme disease. Six patients subsequently had a new episode of erythema migrans. CONCLUSIONS: About 90 percent of children with Lyme disease present with erythema migrans, which is an early stage of the disease. The prognosis is excellent for those with early Lyme disease who are treated promptly with conventional courses of antimicrobial agents.

A phylogenetic approach to following West Nile virus in Connecticut.

The 1999 outbreak of West Nile (WN) virus in the northeastern United States was the first known natural occurrence of this flavivirus in the Western Hemisphere. In 1999 and 2000, 82 independent Connecticut WN virus isolates were cultured from nine species of birds, five species of mosquitoes, and one striped skunk. Nucleotide sequences obtained from these isolates identified 30 genetic changes, compared with WN-NY99, in a 921-nt region of the viral genome beginning at nucleotide position 205 and ending at 1125. This region encodes portions of the nucleocapsid and envelope proteins and includes the entire coding regions for the premembrane and membrane proteins. Amino acid changes occurred at seven loci in six isolates relative to the WN-NY99 strain. Although 34 of the isolates showed sequences identical to the WN-NY99 isolate, we were able to show geographical-based clusters of mutations. In particular, 26 isolates were characterized by mutation of C to T at position 858. This group apparently originated in Stamford, CT and disseminated to sites located as far as 54 miles from Stamford. Sequences of WN virus isolated from both brain and heart tissues from the same avian host were identical in all 14 tested individual birds, suggesting that the mutations we have documented are real and not caused by culture, RNA extraction, or PCR procedures. We conclude that this portion of the viral genome will enable us to follow the geographical and temporal movement of variant WN virus strains as they adapt to North America.

"Nobody gives a damn if I live or die": violence, drugs, and street-level prostitution in inner-city Hartford, Connecticut.

Drawing on the tenets of critical medical anthropology, this article illustrates the relation between violence, drug use, prostitution, and HIV risk in a group of 35 impoverished women living in inner-city Hartford, Connecticut. The study presented here provides an illustration of the role prostitution plays in the SAVA (Substance Abuse, Violence, and AIDS) syndemic as conceptualized by Singer (1996). By focusing on the life experiences of women engaged in street-level prostitution, this article attempts to fill the gaps in research that deals simultaneously with these mutually reinforcing epidemics. It shows that street-walkers' continuous exposure to violence, both as victims and as witnesses, often leaves them suffering from major emotional trauma. In the absence of adequate support services, women who have been victimized may turn to drug use in an attempt to deal with the harsh realities of their daily lives. In turn, the need for drugs, coupled with a lack of educational and employment opportunities, may lead women into prostitution. Life on the street increases women's risk for physical, emotional, and sexual abuse as well as their risk for HIV/AIDS. Exposure to traumatic experiences deepens the dependence on drugs, completing a vicious cycle of violence, substance abuse, and AIDS risk.

Retention in methadone maintenance treatment programs, Connecticut and Massachusetts, 1990-1993.

The goal of this study was to identify factors associated with six- and 12-month retention in methadone maintenance treatment programs (MMTPs) in Massachusetts and Connecticut. Data was obtained from 674 participants, clinic records, and clinic staff. Ethnographic and logistic regression analyses were conducted. Overall, 69% and 48% of the clients remained in treatment at six months and 12 months, respectively. The MMTPs were categorized as either a 12-Step, case management, or primary care model. Factors independently associated with retention in treatment at six months were each one-year increase in age of client (OR 1.05), injecting at three months (OR 0.47), and enrollment in the primary care model (OR 2.10). The same factors were associated with 12-month retention in treatment. To retain clients in MMTPs-which should, in turn, help reduce drug use and prevent HIV transmission among IDUs-younger IDUs and clients still injecting at three months after entering drug treatment may need additional services from the staff, or alternative treatment regimens. MMTP directors should consider differences between these programs and, if appropriate, make changes to increase retention in treatment.

Occupational tuberculosis among deputy sheriffs in Connecticut: a risk model of transmission.

OBJECTIVES: The purpose of this study was to identify risk factors for tuberculin skin test conversions among non-infected deputy sheriffs in Connecticut and during an out-break in an urban lock-up. METHODS: 377 tuberculin skin-test negative sheriffs statewide in 1994-1995 and 37 sheriffs in the lock-up in 1995 were screened and questionnaires administered. Cellblock volumetric air flow was measured. The Wells-Riley model of airborne transmission [C = S(1-e-Iqpt/Q)] was applied to the epidemiologic and ventilation data. RESULTS: Statewide, of 377 sheriffs screened, 22 (5.8%) had positive skin tests. Risk factors included older age (p < .0075) and longer tenure (p < .036). In the lock-up, of 37 sheriffs screened, 4 (10.8%) had positive skin tests. Measured mean outside air flow per occupant (8.0 cfm; S.D. = 2.2) was below design (15 cfm) and recommended (20 cfm) standards. Mathematical modeling estimated that TB transmission would be reduced by 62.5 percent with ventilation at design specifications. CONCLUSIONS: Inadequate ventilation may increase the risk for occupational transmission of tuberculosis. Since lock-ups do not have the time to conduct inmate TB screenings, supplemental engineering controls may be required.

A case-control study of occupation and breast-cancer risk in Connecticut.

BACKGROUND: Several occupations have recently been related to breast-cancer. The results, however, are inconsistent. We analyse data from a case-control study of breast cancer in Connecticut conducted in 1994-97 to further examine the potential relationship between occupation and breast-cancer risk. METHODS: A total of 608 breast-cancer cases and 609 controls, 31-85 years old, were included in the study. Information regarding occupation and other breast-cancer risk-factors was obtained through in-person interviews by trained interviewers, using a standardised, structured questionnaire. RESULTS: after adjustment for major breast-cancer risk-factors, a significantly increased risk of breast cancer was observed for teachers and librarians [odds ratio (OR), = 1.9, 95% confidence interval (CI) 1.3-2.7]. A significantly reduced risk, on the other hand, was observed for technicians and related supports (OR = 0.5, 95% CI 0.3-0.9). No other occupational groups showed a significant association with breast-cancer risk. CONCLUSIONS: The observed increase in breast-cancer risk among teachers and librarians is consistent with most earlier studies. It is currently unknown, however, what factors may explain the observed increase. Considering that teachers and librarians represent one of the largest single occupational groups among employed US women, further investigation of this association is warranted.

Population-based incidence and characteristics of community-onset Staphylococcus aureus infections with bacteremia in 4 metropolitan Connecticut areas, 1998.

This study retrospectively analyzed the magnitude and epidemiology of community-onset Staphylococcus aureus (COSA) infections and methicillin-resistant S. aureus (MRSA) infections in 4 Connecticut metropolitan areas (population, 1.1 million). The study looked at hospital medical records of persons admitted with S. aureus bacteremia in 1998. COSA was categorized as "health care associated," "with underlying medical condition," or "no underlying medical condition." Overall, 48% of S. aureus bacteremic infections were COSA (incidence, 17 cases/100,000 persons). Incidence increased with age and higher population density. In all, 62% of infections were health care associated; 85% of the remaining cases had underlying medical conditions. MRSA accounted for 16% of health care-associated cases and cases with underlying conditions but no cases with no underlying conditions. COSA bacteremic infections are as common as those due to pneumococci. MRSA is a well-established cause of COSA among persons at high medical risk for S. aureus infection. Additional study to understand community-onset MRSA acquisition is needed.

Epidemiology of community-onset candidemia in Connecticut and Maryland.

BACKGROUND: Almost one-third of patients with bloodstream infections with Candida species (candidemia) have onset of disease that occurs outside of the hospital or < or = 2 days after hospital admission (i.e., community-onset candidemia). We compared the characteristics of patients who developed candidemia by the timing of onset of infection. METHODS: Incident episodes of candidemia were identified through active, population-based surveillance in Connecticut and in Baltimore and Baltimore County, Maryland, during 1 October 1998-30 September 2000. The molecular subtypes of a sample of 45 Candida parapsilosis isolates were evaluated using Southern blots hybridized with the complex probe Cp3-13. RESULTS: Overall, 356 (31%) of the 1143 incident episodes of candidemia were classified as community-onset disease (occurring < or = 2 days after hospital admission), and 132 (37%) were caused by Candida albicans, 89 (25%) were caused by Candida glabrata, 57 (16%) were caused by C. parapsilosis, and 53 (15%) were caused by Candida tropicalis. Community-onset disease was less likely to be associated with concurrent immunosuppressive therapy, recent surgery, or use of a central venous catheter, compared with inpatient disease. Among patients with community-onset disease, the median time from blood culture to initiation of antifungal treatment was 2.7 days, the 30-day case-fatality rate was 26%, and 262 patients (75%) had been hospitalized at least once in the previous 3 months. Although there were few differences between patients with very recent hospitalization (in the previous 1 month), less recent hospitalization (previous 1-3 months), and no documented past hospitalization, C. parapsilosis was more frequently associated with community-onset disease as hospitalization became more distant. C. parapsilosis strains tended to be unique to the patient, with little similarity found between strain types, on the basis of epidemiologic classification of patients. CONCLUSION: We report that community-onset candidemia is common and occurs in patients with extensive contact with the health care system. Disease caused by C. parapsilosis tends to involve unique strains.

Diarrheagenic Escherichia coli infection in Baltimore, Maryland, and New Haven, Connecticut.

BACKGROUND: Diarrhea remains a common complaint among US patients who seek medical attention. METHODS: We performed a prospective study to determine the etiology of diarrheal illness among patients and control subjects of all ages presenting to the emergency departments and outpatient clinics of 2 large academic hospitals in Baltimore, Maryland, and New Haven, Connecticut. We used molecular methods to detect the presence of diarrheagenic Escherichia coli pathotypes, including enteroaggregative E. coli (EAEC), as well as Shiga toxin-producing, cytodetaching, enterotoxigenic and enteropathogenic E. coli. RESULTS: Of the pathotypes sought, only EAEC was found in an appreciable proportion (4.5%) of case patients, and it was found more frequently among case patients than control subjects (P<.02). Surprisingly, EAEC was the most common bacterial cause of diarrhea in our population. EAEC was common in all age strata and was not associated with foreign travel or immunodeficiency. EAEC infection is frequently accompanied by fever and abdominal pain, though this did not happen more frequently in patients with EAEC infection than in patients with diarrhea due to other causes. CONCLUSIONS: Our data suggest that EAEC infection should be considered among persons with diarrhea that does not yield another known etiologic agent.

Comparison of the reservoir competence of medium-sized mammals and Peromyscus leucopus for Anaplasma phagocytophilum in Connecticut.

In the northeastern United States, Anaplasma phagocytophilum, the agent of human granulocytic ehrlichiosis (HGE), is transmitted by the tick vector Ixodes scapularis. The white-footed mouse Peromyscus leucopus is a competent reservoir for this agent, but the reservoir competence of non-Peromyscus hosts of I. scapularis has not been studied. Here, we report data confirming reservoir competence of medium-sized mammals for A. phagocytophilum. Raccoons, Virginia opossums, gray squirrels, and striped skunks were live-trapped in June-August of 1998-1999 at two locations in Connecticut. Captured animals were kept for several days at the laboratory in wire-mesh cages over water to allow naturally attached ticks to drop off. Samples of blood and serum were taken from each animal prior to its release at the site of capture. Engorged ticks collected from each animal were allowed to molt. Resulting I. scapularis nymphs and adults were tested for the presence of A. phagocytophilum DNA by polymerase chain reaction, as were the blood samples from the animals. A. phagocytophilum DNA was detected in the blood of >10% of the raccoons tested. Raccoons, opossums, squirrels, and skunks produced adult I. scapularis infected with the agent of HGE. Prevalence of infection was the highest in adult ticks fed as nymphs upon raccoons (23%) and the lowest in those fed upon skunks and opossums (5-7%). The agent was present in nymphal I. scapularis fed as larvae upon raccoons and squirrels, but not in ticks fed upon skunks or opossums. We also tested the ability of I. scapularis to transmit A. phagocytophilum to laboratory-reared white-footed mice after acquiring it from medium-sized mammals. Ticks that acquired the agent from raccoons and squirrels successfully transmitted it to mice. Thus, raccoons and gray squirrels are reservoir-competent for the agent of HGE-they become naturally infected, and are capable of transmitting the infection to feeding ticks.
