Recommendations for raloxifene use in daily clinical practice in the Swiss setting

Raloxifene is the first selective estrogen receptor modulator that has been approved for the treatment and prevention of osteoporosis in postmenopausal women in Europe and in the US. Although raloxifene reduces the risk of invasive breast cancer in postmenopausal women with osteoporosis and in postmenopausal women at high risk for invasive breast cancer, it is approved in that indication in the US but not in the EU. The aim was to characterize the clinical profiles of postmenopausal women expected to benefit most from therapy with raloxifene based on published scientific evidence to date.

Assessment of smoking behaviour in the dental setting. A study comparing self-reported questionnaire data and exhaled carbon monoxide levels

The present study validated the accuracy of data from a self-reported questionnaire on smoking behaviour with the use of exhaled carbon monoxide (CO) level measurements in two groups of patients. Group 1 included patients referred to an oral medicine unit, whereas group 2 was recruited from the daily outpatient service. All patients filled in a standardized questionnaire regarding their current and former smoking habits. Additionally, exhaled CO levels were measured using a monitor. A total of 121 patients were included in group 1, and 116 patients were included in group 2. The mean value of exhaled CO was 7.6 ppm in the first group and 9.2 ppm in the second group. The mean CO values did not statistically significantly differ between the two groups. The two exhaled CO level measurements taken for each patient exhibited very good correlation (Spearman's coefficient of 0.9857). Smokers had a mean difference of exhaled CO values of 13.95 ppm (p < 0.001) compared to non-smokers adjusted for the first or second group. The consumption of one additional pack year resulted in an increase in CO values of 0.16 ppm (p = 0.003). The consumption of one additional cigarette per day elevated the CO measurements by 0.88 ppm (p < 0.001). Based on these results, the correlations between the self-reported smoking habits and exhaled CO values are robust and highly reproducible. CO monitors may offer a non-invasive method to objectively assess current smoking behaviour and to monitor tobacco use cessation attempts in the dental setting.

Debulking surgery in the setting of very high-risk prostate cancer scenarios

What's known on the subject? and What does the study add? Nowadays radical prostatectomy (RP) is considered an effective treatment in high-risk prostate cancer (PCa) and the indications for a surgical approach are expanding, even in cases of very high PSA or node-positive disease. We explored the outcomes of debulking surgery in the setting of these very high-risk PCa patients, in order to assess its feasibility. This review confirms the important role achieved by surgery in the complex setting of patients with very high-risk PCA. Excellent survival rates have been reported, even when PSA exceeds 100 ng/mL. The completion of RP with lymphadenectomy might give a survival benefit in patients who were found intraoperatively to be node-positive. Furthermore, salvage RP confirmed to be the most effective treatment option after RT failure. On the contrary, up-to-date surgery of isolated nodal recurrences has shown only little benefit. Finally, there is no evidence supporting the efficacy of debulking surgery in metastatic or in hormone-refractory tumours. An accurate selection of the patient is essential.

Transmission dynamics of extended-spectrum β-lactamase-producing Enterobacteriaceae in the tertiary care hospital and the household setting

Studies about transmission rates of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in hospitals and households are scarce.

Practicability of nitrogen multiple-breath washout measurements in a pediatric cystic fibrosis outpatient setting

BACKGROUND: Although lung clearance index (LCI) is a sensitive indicator of mild cystic fibrosis (CF) lung disease, it is rarely measured due to lengthy protocols and the commercial unavailability of multiple-breath washout (MBW) setups and tracer gases. We used a newly validated, commercially available nitrogen (N(2) ) MBW setup to assess success rate, duration, and variability of LCI within a 20 min timeframe, during clinical routine. We also evaluated the relationship between LCI and other clinical markers of CF lung disease. METHODS: One hundred thirty six children (83 with CF) between 4 and 16 years were studied in a pediatric CF outpatient setting. One hundred eighteen out of 136 children were naïve to MBW. Within 20 min, each child was trained, N(2) MBW was performed, and LCI was analyzed. We assessed intra- and between-test reproducibility in a subgroup of children. RESULTS: At least one LCI was feasible in 123 (90%) children, with a mean (range) of 3.3 (1.2-6.4) min per test. Two or more measurements were feasible in 56 (41%) children. Comparing LCI in CF versus controls, LCI mean (SD) was 12.0 (3.9) versus 6.1 (0.9), and the intra- and inter-test coefficient of repeatability was 1.00 versus 0.81 and 0.96 versus 0.62, respectively. LCI was correlated with spirometry, blood gases, and Pseudomonas aeruginosa infection. CONCLUSIONS: Using available N(2) MBW equipment, LCI measurements are practical and fast in children. LCI is correlated with markers of CF lung disease. Longer timeframes would be required for triplicate N(2) MBW tests in inexperienced children. Pediatr Pulmonol. © 2012 Wiley Periodicals, Inc.

Forced-use therapy for children with cerebral palsy in the community setting: a single-blinded randomized controlled pilot trial

The aim of this study was to elucidate the feasibility, efficacy, and sustainability of a home-based, two-week, forced-use therapy (FUT) program for children with hemiplegic cerebral palsy (CP).

Wie effektiv sind systematische Rückmeldungen des Therapieverlaufs an den Therapeuten? Eine empirische Studie in einem stationär-verhaltenstherapeutischen Setting

Theoretischer Hintergrund: Die systematische Rückmeldung des Therapieverlaufs an den Therapeuten erwies sich in mehreren Studien an ambulant behandelten, überwiegend gering beeinträchtigten Patienten als effektives Mittel, um die Wirksamkeit psychotherapeutischer Behandlungen für potenziell problematische Patienten zu steigern. Fragestellung: Lassen sich diese Befunde auch in einem stationär-verhaltenstherapeutischen Setting replizieren und inwieweit sind sie wirklich auf misserfolgsgefährdete Patienten beschränkt? Methode: In einem randomisierten Gruppenvergleich (N = 118) erhielt die Hälfte der Therapeuten ein systematisches Feedback über den Therapieverlauf. Ergebnisse: Die Patienten in der Feedback-Bedingung verbesserten sich bei allen untersuchten Therapieerfolgsmaßen stärker als die Patienten der Kontrollgruppe. Schlussfolgerung: Ein systematisches Feedback des Therapieverlaufs an den Therapeuten führt zu einer Verbesserung der Effektivität stationär-verhaltenstherapeutischer Behandlungen. Zukünftige Forschung sollte nach Wegen suchen, die monetären und psychologischen Kosten von Feedbacksystemen zu reduzieren, um deren Einsatz in Settings der Routineversorgung zu erleichtern.

Vulvovaginal-swab or first-catch urine specimen to detect Chlamydia trachomatis in women in a community setting?

Screening for chlamydia in women is widely recommended. We evaluated the performance of two nucleic acid amplification tests for detecting Chlamydia trachomatis in self-collected vulvovaginal-swab and first-catch urine specimens from women in a community setting and a strategy for optimizing the sensitivity of an amplified enzyme immunoassay on vulvovaginal-swab specimens. We tested 2,745 paired vulvovaginal-swab and urine specimens by PCR (Roche Cobas) or strand displacement amplification (SDA; Becton Dickinson). There were 146 women infected with chlamydia. The assays detected 97.3% (95% confidence interval [CI], 93.1 to 99.2%) of infected patients with vulvovaginal-swab specimens and 91.8% (86.1 to 95.7%) with urine specimens. We tested 2,749 vulvovaginal-swab specimens with both a nucleic acid amplification test and a polymer conjugate-enhanced enzyme immunoassay with negative-gray-zone testing. The relative sensitivities obtained after retesting specimens in the negative gray zone were 74.3% (95% CI, 62.8 to 83.8%) with PCR and 58.3% (95% CI, 46.1 to 69.8%) with SDA. In community settings, both vulvovaginal-swab and first-catch urine specimens from women are suitable substrates for nucleic acid amplification tests, but enzyme immunoassays, even after negative-gray-zone testing, should not be used in screening programs.
