Clinical breast examination and breast self-examination. Past and present effect on breast cancer survival.

Increasing attention to self-detection of breast masses and clinical breast examination during this century have contributed to a progressive reduction in the size of breast cancers at detection and a progressive improvement in survival. Mammography is more sensitive than breast palpation for the detection of breast cancer, however, mammography does not detect all palpable cancers and additional interval cancers become palpable between screenings. Breast self-examination, clinical breast examination, and mammography are complementary screening modalities. In populations where mammography is not available or is not appropriate as a screening modality, clinical breast examination and breast self-examination are particularly important.

Training obstetric and family practice residents to give smoking cessation advice during prenatal care.

OBJECTIVE: Our objective was to determine the effectiveness of training obstetric and family practice residents to provide smoking cessation advice. STUDY DESIGN: The effectiveness of the trained residents' advice was assessed from exit interviews of pregnant smokers taking part in a randomized, controlled trial of smoking cessation advice. Exit interview responses were compared by chi 2 analysis. RESULTS: Training resulted in significant changes in the advice provided by the residents, with greater emphasis on gaining a commitment to smoking behavior change, but not in the average time providing the advice, approximately 3 minutes. Adherence to the protocol was maintained at 80%. Significantly more women who received the brief structured advice agreed to stop smoking (54%) or cut down their cigarette consumption (28%) compared with women in the control group (14% and 6%, respectively), p = 0.0001. CONCLUSION: The structured advice consistently provided by the trained residents was effective in gaining commitments from pregnant smokers to change their smoking behavior.

Smoking cessation among self-quitters.

We examined cessation among 630 smokers who quit abruptly on their own. Continuous, complete abstinence rates were 33% at 2 days, 24% at 7 days, 22% at 14 days, 19% at 1 month, 11% at 3 months, 8% at 6 months postcessation, and 3% at 6 months with biochemical verification. Slipping (smoking an average of less than 1 cigarette/day) was common (9% to 15% of subjects) and was a strong predictor of relapse; however, 23% of long-term abstainers slipped at some point. These results challenge beliefs that most smokers can initially stop smoking and that most relapse occurs later on postcessation.

Acquired immunodeficiency syndrome/human immunodeficiency virus risk behavior among gay men in small cities. Findings of a 16-city national sample.

BACKGROUND: Most research on acquired immunodeficiency syndrome has been conducted in several of the country's largest cities, and little is known about the current level of human immunodeficiency virus risk taking among gay men in other geographical areas. The purpose of this study was to determine the frequency of risk behavior practices among gay men in smaller communities. METHOD: A large sample of men who patronized gay bars in 16 small and moderate-size cities drawn from six states in four different regions of the country was surveyed to determine the frequency of high-risk behavior and factors influencing risk taking. Eighty-five percent of men in all cities' bars completed all survey measures. The community samples were 1991 men; mean age, 31.3 years; mean education, 10.6 years; 90% were white and 10% were of other ethnicities. All participants provided detailed information on their sexual behavior practices over the preceding 2 months and completed measures assessing their perceived peer norms concerning safer sex practices and risk avoidance, intentions to avoid risk, personal risk estimation, acquired immunodeficiency syndrome risk knowledge, perceived threat of acquired immunodeficiency syndrome/human immunodeficiency virus, and serostatus testing history. RESULTS: High-risk patterns were still common among gay men in these smaller cities; nearly one third of all men had engaged in unprotected anal intercourse an average of eight times in the past 2 months, usually outside monogamous relationships. High-risk behavior was most strongly associated with beliefs that safer sex practices would not be well accepted by peers, weak intentions to use condoms, underestimation of personal vulnerability to the acquired immunodeficiency syndrome, younger age, and higher levels of overall sexual activity. Nine percent of men tested said they were seropositive. CONCLUSIONS: Growing human immunodeficiency virus prevalence and continued high rates of risk behavior indicate that a new "front line" for human immunodeficiency virus prevention among homosexually active men has shifted to the country's smaller cities. Community prevention efforts in these areas are urgently needed to avert sharp increases in future human immunodeficiency virus infections in this population.

Relative effectiveness of methods of breast self-examination.

This study investigated the effectiveness of different methods of breast self-examination (BSE) on coverage of breast area and lump detection, using a factorial design, pairing three search patterns (concentric circle, radial spoke, vertical strip) with two finger palpation techniques (small circular movements, sliding movements). Ninety-seven female undergraduates were randomly assigned to one of six BSE training conditions which were identical except in the BSE search pattern and finger palpation technique explained by the instructor. Following the 20-min, small-group training, subjects' coverage of breast area was assessed by scoring their BSE performance on a breast board. Lump detection was determined by the number of lumps correctly identified in silicone breast models. Results indicated that the vertical strip pattern was associated with significantly greater coverage of the breast area. There were no significant differences in lump detection; however, the sliding finger palpation technique resulted in significantly more false identifications of lumps.

The effects of EMG feedback training during problem solving: a case study.

The present case study investigated the effects of competing task demands on biofeedback training to reduce frontalis muscle tension. Baseline levels of frontalis muscle tension were recorded for relaxation and problem solving. The subject was trained to decrease muscle tension with biofeedback for the problem-solving task alone. The results indicated that EMG training during problem-solving was successfully accomplished. Frontalis muscle tension during relaxation baseline did not change as a result of reductions in muscle tension during problem-solving feedback training. This suggests that the decrease of muscle tension cannot be attributed to reductions in overall muscle tension levels. Instead, training was specific to the problem-solving feedback phases. Additionally, it was found that accuracy in problem-solving did not decline as a result of simultaneous feedback training. Thus EMG biofeedback training can be accomplished and exercised without disruption of ongoing mental activity.
