ABSTRACT
OBJECTIVE: The efforts of the authors are to evaluate the role of performing a Papanicolaou (Pap) smear at the time of colposcopy. MATERIALS AND METHODS: This retrospective chart review included patients from 2004 to 2009 who underwent cold knife cone (CKC) biopsy or loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia types 2 and 3 (CIN 2 and 3) or patients with discrepancy between Pap and colposcopic results. All patients presented to the gynecology clinics in a tertiary care hospital. Results were compared which included: the abnormal Pap smear which led to referral for colposcopy, the Pap smear performed at the time of colposcopy, the colposcopic biopsy, and the excisional biopsy. Interpretation of results was calculated with Cohen's K Statistics. RESULTS: One hundred forty-seven patients qualified for the study. One hundred five patients had excisional biopsy proven high-grade squamous intraepithelial lesion (HSIL). Eighty-two of these high-grade excisional pathology results were preceded by high-grade Pap cytology at the time of colposcopy; however 23 Pap cytology results indicated either low-grade squamous intraepithelial lesion (LSIL) or negative (20 and 3 respectively), but were followed by an excisional procedure revealing high-grade pathology. Eighty-one colposcopic biopsies confirmed high-grade excisional biopsy pathology. However, 24 colposcopic biopsies were low-grade or negative (13 and 11 respectively), but followed by a high-grade excisional biopsy. CONCLUSION: The addition of a Pap smear at the time of colposcopy has the potential role of recognizing high-grade cervical dysplasia.

We sought to evaluate survival of liver transplant candidates living in geographic areas with limited access to specialized transplant centers (TxC). We analyzed survival outcome among candidates listed for liver transplant in United Network of Organ Sharing (UNOS) Region 4 from 2004 to 2010. Candidates were stratified into three groups according to the distance from the patient's residence to the closest hospital with a liver transplant program: Group 1 (Gr 1) <30 miles (m), Group 2 (Gr 2) 30-60 m and Group 3 (Gr 3) >60 m. Of the 5673 patients included in the study, 49% resided >30 m from a TxC. Eight percent of the cohort experienced death or dropped out of the list due to medical condition deterioration, with worse outcomes for Gr 2 and Gr 3 (8.5% and 9.9%, respectively, vs. 6.5% for Gr 1 [p < 0.001]). Among patients with a MELD score <20, mortality was higher in Gr 2 and Gr 3 compared to Gr 1 (p < 0.001). We conclude that for Region 4, the mortality risk in patients living >30 m from a TxC is higher. We suggest that the variable "distance from a TxC" should be used to improve the estimate of the mortality risk for patients on the waiting list.

BACKGROUND: Hepatocellular carcinoma (HCC) is third most common cause of tumour-related death in the US with hepatitis C virus (HCV) the most common aetiology. Surgical resection and tumour ablation are curative in patients who cannot be transplanted. With native liver having cirrhosis, HCC recurrence is a potential problem. AIM: To perform a systematic review and meta-analysis of studies evaluating efficacy of IFN to prevent HCC recurrence after its curative treatment in HCV-related cirrhosis. METHODS: Ten studies (n = 645, 301 treated with IFN) on the use of IFN after resection or ablation of HCV-associated HCC were analysed. RESULTS: Pooled data showed benefit of IFN for HCC prevention with OR (95% CI) of 0.26 (0.15-0.45); P < 0.00001. The proportion of patients surviving at 5 years (n = 505 in 6 studies) was in favour of IFN with OR of 0.31 [(95% CI 0.21-0.46); P < 0.00001]. Data were homogeneous for HCC recurrence (chi(2) 12.05, P = 0.21) and survival (chi(2) 6.93, P = 0.44). The benefit of IFN was stronger with sustained virological response compared with nonresponders for HCC recurrence [0.19 (0.06-0.60); P = 0.005] and survival [0.31 (0.11-0.90); P = 0.03]. CONCLUSION: Interferon treatment after curative resection or ablation of HCC in HCV-related cirrhotics prevents HCC recurrence and improves survival.

BACKGROUND: Little research has been conducted on changes in perceived health after an industrial accident. Using data from an ongoing survey on stress and health in a petrochemical complex in Texas City, Texas, the associations of a petrochemical accident with perceived health changes were examined. METHODS: The mean changes in perceived mental and physical health across pre-accident, within-accident, and post-accident categories were compared. The association of these categorical variables with the change in perceived mental and physical health using multiple regression was also examined. RESULTS: Significant declines in both perceived mental and physical health were observed for the sample. Regression analyses showed that middle age, lower education level and reported damage in the neighbourhood were associated with decreases in perceived mental health. Lower education level, explosion impact, and distance from the explosion site were associated with decreases in perceived physical health. CONCLUSIONS: These results indicate that both pre-accident and within-accident variables, such as education level and explosion impact, are associated with decreases in perceived physical and mental health. Even a modest event within the range of accidents and disasters was shown to be associated with negative health outcomes for a population-based sample.

OBJECTIVES: To explore the relationship between systolic and diastolic blood pressure and risk of 6-year, all-cause mortality in men and women age 65 to 84 versus those 85 and older. DESIGN: A population-based longitudinal study. SETTING: This study was conducted at four different sites: East Boston, Massachusetts; New Haven, Connecticut; two rural counties in Iowa; and Piedmont, North Carolina. PARTICIPANTS: 12,802 community-dwelling persons age 65 and older. MEASUREMENTS: Baseline measurements collected include demographics, self-reported chronic medical conditions, blood pressure measurements, medications, health habits, and hospitalizations. RESULTS: Unadjusted actuarial survival analyses show that men age 65 to 84 years with systolic blood pressure < 130 mmHg have significantly lower mortality compared with those with systolic blood pressure > or = 180 mmHg (P < .0001). In contrast, men 85 and older with systolic blood pressure > or = 180 mmHg have significantly lower mortality compared with those with systolic blood pressure < 130 mmHg (P < .0001). In Cox proportional hazards analyses controlling for other predictors of survival, the hazard of death associated with each 10-mmHg increase in systolic blood pressure is positively associated among men age 65 to 84 years and negatively associated among men age 85 and older (Hazard ratio and 95% confidence interval (CI): 1.04 (1.01, 1.07) for younger men vs 0.92 (0.86, 0.99) for older men). Among women age 65 to 84, the hazard of death significantly increased with increase in systolic blood pressure (P < .0001), while there was no relationship between level of systolic blood pressure and survival in women 85 and older. Both men 65 to 84 years old and those 85 and older showed a negative relationship between diastolic blood pressure and all-cause mortality (Hazard ratio 0.93, 95% CI (0.88-0.97) for men age 65-84 years, and Hazard ratio 0.90, 95% CI 0.80-1.02 for men 85 and older). CONCLUSION: In men age 85 and older, higher systolic blood pressure is associated with better survival.

OBJECTIVES: To determine whether a Traffic Sign Recognition Test (TSRT) can identify older drivers who recently had a motor vehicle crash (MVC). DESIGN: Retrospective, matched, case-control study. SETTING: Licensed drivers in Galveston, Texas. PARTICIPANTS: 60 crash and 60 control subjects matched for age and gender. Cases were identified from accident records. Controls were selected from a randomized list of licensed drivers in Galveston. MEASUREMENTS: Folstein Mini-Mental State Examination (MMSE) and the TSRT. RESULTS: A TSRT significantly distinguished between case and control groups (P = .01). The MMSE did not (P = .61). A TSRT predicted MVC in a multivariate analysis controlling for education, MMSE score, race/ethnicity, and mileage driven/year (odds ratio = 0.88, 95% confidence interval = 0.77-1.00). CONCLUSION: A TSRT successfully identifies older drivers with a recent MVC, but the test lacks sensitivity and specificity. A prospective study is needed to further delineate the TSRT's usefulness in predicting crash risk in older drivers.

This paper examines whether an older patient's concerns about surgical treatment of breast cancer--such as fear of dying or about losing a breast--affect the treatment recommendations by their surgeons. A sample of 137 older women diagnosed with early stage breast cancer between 1994 and 1996 were interviewed within 2 months of diagnosis to determine demographic characteristics, their attitudes about breast cancer treatments, and which surgical treatment their surgeon initially recommended. The treatment preferences of the 35 surgeons treating these women were ascertained by asking them what treatment they would usually recommend to a hypothetical 75-year-old woman with early stage breast cancer. Patients who reported their feelings about losing a breast as 'very important' were less likely to be recommended mastectomy (Odds Ratio (OR) = 0.39; 95% (Confidence Interval) CI 0.16, 0.94), while patients who reported fear of dying from breast cancer as 'very important' were more likely to be recommended mastectomy (OR = 4.60; 95% CI 1.94, 11.59), after adjusting for surgeons' age and the surgeons' treatment preference when presented with a hypothetical patient. It is concluded that surgeons integrate patients' attitudes and concerns into their treatment recommendations.

OBJECTIVE: To review respiratory distress syndrome (RDS) mortality since the introduction of surfactant. DESIGN: Population-based historical cohort study. METHODS: United States vital statistic data were used for the years 1987 to 1995. Linked birth and infant death file data were available for the years 1987 to 1991 and for 1995. US natality and mortality files were used for the years 1992 to 1994. RESULTS: Whereas overall infant mortality decreased 25% over the-9 year period from a rate of 979 deaths/100,000 live births (LB) to a rate of 736, mortality attributed to RDS decreased 56% from a rate of 84 to 37. The crude black:white relative risk for RDS-related mortality increased from 2.02 in 1987 to 2.76 in 1995. The largest and most consistent drop in RDS-related mortality occurred in the 2000 to 2499 gm birth weight and 33- to 36-week gestation groups; average annual decline = 20%. There was a change in the distribution of the underlying causes of death over the 9-year period with an increase in the proportion of mortality attributed to prematurity. CONCLUSION: Since the advent of surfactant there has been a marked reduction in mortality attributed to RDS. Of concern is the increasing disparity between black and white RDS-related mortality.

BACKGROUND: Three important events in the history of breast cancer treatment occurred between 1983 and 1995: a large clinical trial, first lady Nancy Reagan's choice of mastectomy and the publishing of an NIH consensus statement. OBJECTIVE: To assess the effects of these events on use of breast conserving surgery (BCS). RESEARCH DESIGN: Data from the cohort study of the surveillance, epidemiology and end results (SEER) Program from 1983 to 1995 were divided into four periods: Baseline, Trial, Celebrity, and Consensus. SUBJECTS: Of the women, 169,466 diagnosed with early stage breast cancer in nine SEER areas. MEASURES: Monthly percentages of BCS. RESULTS: A linear regression model generated a separate intercept and slope term for four time periods, adjusting for demographic characteristics of breast cancer patients. For the Baseline, Celebrity and Consensus Periods, slopes indicated an increasing use of BCS which varied between 0.24% and 0.28% per month. Slopes for these three periods were not statistically different (p = 0.120). In contrast, there was no change in use of BCS during the trial period (p = 0.247). We tested the magnitude of discontinuity between periods. At the beginning of the trial, celebrity and consensus periods, there were increases in BCS of 5.54% (p < 0.001), -3.55% (p < 0.001), and 2.37% (p < 0.001), respectively. CONCLUSIONS: The use of BCS was substantially affected by the reports of a clinical trial of BCS and by celebrity action. These effects were abrupt but transient. The NIH consensus statement stimulated a small change in use of BCS and may be an important intervention for maintaining the increasing trend in use of BCS since the 1990s.

Approximately 80% of prison inmates are reported to be functionally illiterate. We hypothesized that poor single word decoding (the chief feature of dyslexia) accounts for a significant percentage of that rate. We studied 253 subjects selected randomly from more than 130,000 Texas prison inmates. Among them, we conducted a cross-sectional sample survey of recently admitted Texas inmates, beginning with social and educational background and followed by an educational test battery that included measures of word attack skill and reading comprehension. Deficient performance was defined primarily as single word decoding performance that measured below the 25th percentile on the Woodcock Reading Mastery Test. We found that 47.8% of the inmates were deficient in word attack skills. Word attack skills were detected in each group defined by gender and ethnicity. Nearly two thirds of the subjects scored poorly in reading comprehension.

This study developed and evaluated a method for ascertaining a newly diagnosed breast cancer case using multiple sources of data from the Medicare claims system. Predictors of an incident case were operationally defined as codes for breast cancer-related diagnoses and procedures from hospital inpatient, hospital outpatient, and physician claims. The optimal combination of predictors was then determined from a logistic regression model using 1992 data from the linked SEER registries-Medicare claims data base and a sample of noncancer controls drawn from the SEER areas. While the ROC curve demonstrates that the model can produce levels of sensitivity and specificity above 90%, the positive predictive value is comparatively low (67-70%). This low predictive value is largely the result of the model's limitation in distinguishing recurrent and secondary malignancies from incident cases and possibly from the model identifying true incident cases not identified by SEER. Nevertheless, the logistic regression approach is a useful method for ascertaining incident cases because it allows for greater flexibility in changing the performance characteristics by selecting different cut-points depending on the application (e.g., high sensitivity for registry validation, high specificity for outcomes research). It also allows us to make specific adjustments to population based estimates of breast cancer incidence with claims.

OBJECTIVE: To estimate the changes in birth weight- and gestational age-specific sudden infant death syndrome (SIDS) mortality rates since the publication of the sleep-positioning recommendations by the American Academy of Pediatrics Task Force on Infant Positioning and SIDS. METHODS: This is a historical cohort study using US vital statistic linked birth and infant death certificate files for the years 1991 and 1995. SIDS deaths were identified as any death attributed to International Classification of Diseases, Ninth Revision code 7980, occurring between the 28th and 365th days of life. RESULTS: There were 4871 deaths attributed to SIDS in 1991 for a postneonatal mortality rate of 1.2/1000 postneonatal survivors compared with 3114 deaths in 1995 for a rate of.8/1000. This represents a 33% drop in the postneonatal SIDS mortality from 1991 to 1995. Between 1991 and 1995, SIDS rates declined 38%, 38%, 35%, and 32% for birth weight groupings of 500 to 999 g, 1000 to 1499 g, 1500 to 2499 g, and >/=2500 g, respectively. There were no SIDS deaths attributed to infants weighing <500 g. The SIDS rates declined 27%, 21%, 40%, and 23% for gestational age groups of <29 weeks, 29 to 32 weeks, 33 to 36 weeks, and >/=37 weeks. The rate of decline did not differ significantly across birth weight- or gestational age-specific categories. There was a significant increase in the black:non-black postneonatal SIDS mortality ratio from 2.00 to 2.28, reflecting a smaller decline in birth weight- and gestational age-specific mortality for blacks than observed for the non-black population. CONCLUSION: Postneonatal SIDS mortality decreased significantly across all broad birth weight and gestational age categories. If the decline in the prevalence of prone positioning that has been reported since 1992 has occurred across all birth weight and gestational age, these data support the hypothesis that supine or side sleep positioning is effective in preterm/low birth weight infants as well as term infants.

The objective of this analysis was to determine the prevalence of obesity and its association with selected medical conditions in a non-institutionalized elderly Mexican-American population. Data employed are from a representative sample of 3050 elderly Mexican Americans from the five Southwestern states: Texas, California, Colorado, New Mexico, and Arizona. Complete Body Mass Index (BMI) data were available for 2769 individuals. The in-home survey obtained socio-demographic data, anthropometric measurements, including height and weight, blood pressure readings, self-reported health conditions and depressive symptomatology. It was found that 23% of men and 35% of women were obese (BMI > or =30 kg/m2). Using a weighted logistic regression model, a BMI of > or =26 kg/m2 was associated with a significantly higher risk of diabetes; a BMI of > or =30 kg/m2 was significantly associated with arthritis and measured hypertension and a BMI<22 kg/m2 was associated with a higher likelihood of self-reported cancer. In addition, the prevalence of obesity was found to be much higher in this elderly Mexican-American population than in the general population.

BACKGROUND: Authorities recommend radiation therapy after breast-conserving surgery for breast cancer. Numerous studies have reported that older women diagnosed with breast cancer are less likely to receive radiation after breast-conserving surgery. It is unclear how care of older women with breast cancer has changed over time. METHODS: Women with local or regional stage breast cancer diagnosed between 1983-1995 were identified from the Surveillance, Epidemiology, and End Results (SEER) Cancer Registries. The treatment information in SEER includes type of surgical procedures and receipt of radiation therapy. RESULTS: There were small increases in the percentage of women receiving breast-conserving surgery during the 1980s followed by substantial increases in the 1990s. Age was a major factor in determining receipt of radiation therapy after breast-conserving surgery. A large increase in use of radiotherapy after surgery was observed in women aged > or = 75, from below 30% in 1983 to over 50% in 1995. Women aged > or = 75 diagnosed in 1992-1995 were 1.76 and 2.34 times more likely to receive radiation for local and regional stage respectively, as compared to those in 1983-1987. There was no increase in use of radiation for women aged < 65. CONCLUSIONS: There has been a substantial increase in use of breast-conserving surgery and in receipt of radiation therapy after breast-conserving surgery in older women. However, there was a net increase in the percentage of all women with breast cancer who received this surgery without radiotherapy, due to the large increase in the overall percentage of women receiving this surgery.

BACKGROUND: Sudden infant death syndrome (SIDS) is a major contributor to infant mortality. Previous studies have suggested that infants born of twin pregnancies are at greater risk for SIDS and that a twin who survives after a co-twin dies is at increased risk for SIDS. OBJECTIVE: To attempt to confirm the increased risk of SIDS among and within twin pairs through the use of US vital statistics data. METHODS: We analyzed data from the US-linked birth and infant death certificate tapes for the years 1987 through 1991 to determine the risk of SIDS in twin births compared with singleton births and to describe the characteristics of twin pairs in whom SIDS occurred. The analysis was limited to live births with weights of 500 g or more and gestational ages of 24 weeks or more. We used an algorithm to match co-twins (infants within a twin pair) to measure sex and birth weight concordancy, to identify twin pairs, in which one or both twins died of SIDS; and to examine, when both twins died, whether they died on the same day. RESULTS: There were 23464 singleton SIDS deaths and 1056 twin SIDS deaths during the 5-year period. The crude relative risk for SIDS among twins compared with singleton births was 2.06 (95% confidence interval, 1.94-2.19). The adjusted relative risk independent of birth weight and sociodemographic variables was 1.13 (95% confidence interval, 0.97-1.31). We successfully matched the co-twins of 172029 twin pregnancies. Of these, 767 were twin pregnancies in which one or both twins died of SIDS. Among the 767 twin pregnancies in which one or both twins experienced SIDS, there were only 7 in which both twins died of SIDS (rate ratio, 4.0 per 100000 twin pregnancies). In only 1 of these 7 did both twins die on the same day (rate ratio, 0.58 per 100000 twin pregnancies). The relative risk for a second twin dying of SIDS was 8.17 (90% confidence interval, 1.18-56.67). CONCLUSIONS: Independent of birth weight, twins do not appear to be at greater risk for SIDS compared with singleton births. In addition, the occurrence of both twins dying of SIDS is uncommon, and the occurrence of both twins dying on the same day is extremely uncommon.

OBJECTIVE: To determine the risk factors for colonization or infection with methicillin-resistant Staphylococcus aureus in human immunodeficiency virus (HIV)-infected patients. DESIGN: Retrospective matched-pair case-control study. SETTING: Continuity clinic and inpatient HIV service of a university medical center. POPULATION: Patients with HIV infection from the general population of eastern and coastal Texas and from the Texas Department of Criminal Justice. DATA COLLECTION: Patient charts and the AIDS Care and Clinical Research Program Database were reviewed for the following: age, race, number of admissions, total hospital days, presence of a central venous catheter, serum albumin, total white blood cell count and absolute neutrophil count, invasive or surgical procedures, any cultures positive for S. aureus, and a history of opportunistic illnesses, diabetes, or dermatologic diagnoses. Data also were collected on the administration of antibiotics, antiretroviral therapy, steroids, cancer chemotherapy, and subcutaneous medications. RESULTS: In the univariate analysis, the presence of a central venous catheter, an underlying dermatologic disease, lower serum albumin, prior steroid therapy, and prior antibiotic therapy, particularly antistaphylococcal therapy or multiple courses of antibiotics, were associated with increased risk for colonization or infection with methicillin-resistant S. aureus. Multivariate analysis yielded a model that included presence of a central venous catheter, underlying dermatologic disease, broad-spectrum antibiotic exposure, and number of hospital days as independent risk factors for colonization or infection with methicillin-resistant S. aureus. CONCLUSIONS: In our HIV-infected patient population, prior hospitalization, exposure to broad-spectrum antibiotics, presence of a central venous catheter, and dermatologic disease were risk factors for acquisition of methicillin-resistant S. aureus.

OBJECTIVES: This study examines the effects of health, predisposing, and enabling factors on recognition of a mental health problem, use of formal mental health care, and contact with a specialized mental health provider. METHODS: Interviews were conducted with a probability sample of 3,435 adults. The variables examined include measures of mental health; social and demographic factors; and enabling factors relevant to the help-seeking process. RESULTS: Subjective and objective measures of mental health were associated with the recognition of a mental health problem. The objective assessment of definite need for services was relevant for the use of formal services. However, the subjects' perception of poor mental health was strongly related to receiving care from a mental health specialist. Although interaction with social networks is associated with use of formal services, low economic strain is related to receiving care from the specialty sector. CONCLUSIONS: The results support the importance of using multiple measures of mental health problems. The finding that individuals' perceived economic strain increases the likelihood of receiving specialized care suggests that studies of economic barriers to the use of mental health services might benefit from the adoption of measures that assess perceived economic circumstances.

Needle sharing is one of the principal risk behaviors leading to HIV transmission among injection drug users (IDUs). Shooting galleries, a social context where IDUs rent, share, and borrow needles, are locations usually found near drug markets. This study, which interviewed 1,700 IDUs from May 1989 to June 1990, assesses sociodemographic characteristics and HIV risk behaviors among shooting gallery users in Puerto Rico. Multivariate analyses showed that shooting gallery use is associated with speedball (a concoction of heroin and cocaine) injection, income from illegal activities and previous drug treatment. Shooting gallery users were more likely to rent, share, and borrow needles, and less likely to always use bleach and water to clean needles. Strategies to reduce shooting gallery use among drug injectors are discussed.

OBJECTIVE: A collaborative study was conducted to develop methods for surveys of mental disorder and service utilization in unscreened population-based samples of children and adolescents. METHOD: Probability household samples of youths 9 through 17 years of age were selected at four sites and interviews were conducted with a total of 1,285 pairs of youths and their adult caretakers in their homes. Lay interviewers administered a computer-assisted version of the NIMH Diagnostic Interview Schedule for Children Version 2.3 and structured interviews to assess demographic variables, functional impairment, risk factors, service utilization, and barriers to service utilization. RESULTS: More than 7,500 households were enumerated at four sites, with enumeration response rates above 99%. Across sites, 84% of eligible youth-caretaker pairs were interviewed for about 2 hours each. Ninety-five percent of both youths and caretakers found the interview to be acceptable enough to recommend to a friend. CONCLUSIONS: These findings indicate that large-scale epidemiological surveys of mental disorders and mental health service use involving lengthy interviews in the homes of unscreened population-based samples of youths and their adult caretakers are acceptable to the community and can achieve good response rates. The other reports in this Special Section address the reliability and validity of the various survey instruments and other key findings.
