Risk of noncompliance due to patient discomfort during screening mammogram

1522

Background: There is enough evidence supporting the benefits of screening mammograms than any other screening procedure for the early detection of malignancy. Compliance to the screening method is very important to achieve this purpose. There is some concern about future trends in breast cancer mortality as a decline in rates of mammogram screening has been noticed. Pain during mammography has been recognized as a significant deterrent to breast screening. Hence this study was done to evaluate compliance in screening mammogram and to analyze major reasons for noncompliance. Methods: Randomly selected patients visiting the doctor's office for various reasons were asked about mammogram and their experience. Their responses were tabulated and analyzed statistically. Results: Out of 160 people questioned, 155 patients had mammogram regularly at 1–2 year interval and five patients did not. 50% of respondents were 51–70 years of age, 15% were 50 years or under, and 31% were over 70 years. Ninety patients (58%) reported their mammogram experience was unpleasant, causing pain and bruising. In spite of the discomforts reported, 132 (82.5%) patients said they would continue the screening as recommended. However, 28 patients (17.5%) indicated their intention not to get further mammograms based on their painful experience, unless the screening technology was improved. Conclusions: Breast cancer incidence after peaking in 1998 has decreased 9.8% since then with a 12% decline in women aged 50–60. The sharpest decline was noted from 2003 that could be due to the decrease in the hormone replacement therapy after the Women's Health Initiative report. However, it may also reflect some reduction in screening mammograms from 70% (in 2000) to 66% (in 2005) as estimated by National Health Interview Survey. Various causes were attributed for the decline in screening mammogram rate including the discomfort and pain caused by compression during film mammography. More than 1 in 6 patients refusing to undergo further screening is definitely a sign of concern. Better screening methods like patient controlled compression mammogram reported by Duke University Medical Center or other methods are worth investigating, to improve the compliance of the one of the effective preventive measures.

Clinical effectiveness of alcohol-based products in increasing hand hygiene compliance and reducing infection rates: a systematic review

Reducing the incidence of healthcare-associated infection represents a major challenge. This systematic review of the evidence base considers the clinical effectiveness of incorporating an alcohol-based hand hygiene product into procedures aimed at improving compliance with hand hygiene guidelines, and thereby reducing the incidence of healthcare-associated infections. Multi-component interventions that included alcohol-based products were as effective as those that did not, both in achieving sustained hand hygiene compliance and in reducing infection rates. However, a number of difficulties were encountered in assessing hand hygiene studies: the problem of attributing efficacy to an alcohol-based product when used in a multi-component intervention; the variability inherent in the design of such studies; and how to use data from uncontrolled, unblinded studies in the assessment.

Self-propelled Leidenfrost droplets

We report that liquids perform self-propelled motion when they are placed in contact with hot surfaces with asymmetric (ratchetlike) topology. The pumping effect is observed when the liquid is in the Leidenfrost regime (the film-boiling regime), for many liquids and over a wide temperature range. We propose that liquid motion is driven by a viscous force exerted by vapor flow between the solid and the liquid.

Etanercept therapy in children with treatment-resistant uveitis

OBJECTIVE

To evaluate the safety and efficacy of the tumor necrosis factor fusion protein etanercept in children with treatment-resistant uveitis.

METHODS

Ten children with chronic active uveitis (7 girls and 3 boys, mean age 7.5 years [range 3-12 years]) were enrolled in this prospective study. In 7 children, uveitis was associated with pauciarticular juvenile rheumatoid arthritis. Five children were antinuclear antibody positive. All patients had failed previous therapy with topical steroids and methotrexate and/or cyclosporine. All were treated with etanercept at a dosage of 0.4 mg/kg twice weekly for the first 3 months, and then, if eyes did not improve, with 25 mg twice weekly (mean 1.1 mg/kg) for at least 3 additional months.

RESULTS

At the beginning of the trial, uveitis affected 18 eyes in the 10 children. Within 3 months, 10 of 16 affected eyes (63%; P = 0.017) showed a rapid decrease in anterior chamber cell density, including remission of uveitis in 4 eyes. In children with visual acuity of less than 20/25, 4 of 10 eyes (40%) improved. An exacerbation of uveitis during etanercept therapy occurred in only 1 child (1 of 14 eyes [7%]). Other ocular outcome parameters, such as intraocular pressure, synechia formation, and lens clarity, remained unchanged. Following a dosage increase to an average of 1.1 mg/kg after 3 months in 7 children, no further improvement was noted.

CONCLUSION

Our data suggest that etanercept injected subcutaneously twice a week has a beneficial effect on treatment-resistant chronic uveitis in children. Further controlled studies with etanercept in systemic or topical form are necessary to confirm its efficacy and optimal mode of administration.

Symptomatic improvement of premenstrual dysphoric disorder with sertraline treatment. A randomized controlled trial. Sertraline Premenstrual Dysphoric Collaborative Study Group

CONTEXT

Premenstrual dysphoric disorder is an important cause of symptoms and functional impairment in menstruating women.

OBJECTIVE

To evaluate the efficacy of sertraline hydrochloride for treatment of premenstrual dysphoria by measuring changes in symptom expression and functional impairment.

DESIGN

Two screening cycles followed by 1 single-blind placebo cycle and 3 cycles of randomized, double-blind, placebo treatment.

SETTING

Twelve university-affiliated outpatient psychiatry and gynecology clinics.

PATIENTS

Of the 447 women who requested participation, 243 met criteria for premenstrual dysphoric disorder and were randomized; 200 women completed the study.

INTERVENTION

A flexible (50-150 mg) daily dose of sertraline hydrochloride.

MAIN OUTCOME MEASURES

The Daily Record of Severity of Problems, Hamilton Rating Scale for Depression, Clinical Global Impression Scale, and Social Adjustment Scale.

RESULTS

Mean (+/-SD) total daily symptom scores decreased significantly (P<.001) in the sertraline-treated (64+/-22 to 44+/-19) compared with the placebo-treated (62+/-22 to 54+/-24) groups. Significant improvement (P<.05) was found for all clinically derived symptom clusters (depressive, physical, and anger/irritability symptoms). Hamilton Rating Scale for Depression scores decreased by 44% and 29% in the sertraline and placebo groups, respectively (P<.002). End-point global ratings showed much or very much improvement in 62% of the active treatment group and 34% of the placebo treatment group (P<.001). Reported functional impairment was substantial at baseline. Improvement in psychosocial functioning with treatment was similar to what is found in studies of major depression.

CONCLUSIONS

Sertraline was significantly better than placebo for treatment of premenstrual dysphoria as reflected by symptomatic improvement and change in reported functional impairment. Serotonin reuptake inhibitors such as sertraline are useful therapeutic options for women with premenstrual dysphoria.

A numerical identification system for airways in the lung

A numerical system for identifying airways at any level in the tracheobronchial tree has been developed which appears to be simple, logical, and accurate. The system has been successfully used in the authors' laboratory to expedite morphometric studies of the conducting airways in the tracheobronchial tree. Three simple and direct criteria or rules have been formulated for assignment of an airway identification number (AIN) to any specific pulmonary airway, according to this identification system. Some specific applications of this AIN system have been enumerated and several limitations that the authors have recognized have been described. Workers in the fields of bronchial morphometry and anatomy are invited to consider the possible theoretic and practical utility of this airway identification system.
