Patient Satisfaction and Quality of Life Among Adult Women with Androgenetic Alopecia Using 5% Topical Minoxidil

BACKGROUND: Androgenetic alopecia (AGA) is a common, genetically predisposed condition that begins after puberty and whose frequency increases with age; although biologically benign, AGA can impact patients both psychologically and socially, contributing to an impairment on their quality of life. OBJECTIVE: We sought to evaluate the psychological, social, and quality of life impairments inherent in women with AGA using 5% minoxidil daily for at least six months. DESIGN: Thirty-one women with diffuse central hair thinning and shaft miniaturization who were using 5% minoxidil daily for at least six months responded to a clinical questionnaire and underwent trichoscopy. RESULTS: 83.9 percent (n=26) of the participants reported they were satisfied with the 5% minoxidil treatment and its convenience. Hair loss influenced social life in 54.8 percent (n=17) of the respondents and choice of hair cut/hairstyle in 87.1 percent (n=27) of respondents. For 51.6 percent (n=16) hair loss was slightly increased, although it did not increase after beginning treatment. A frontoparietal pattern (74.2%, n=23), very low capillary density (61.3%, n=19), trichodynia (32.3%, n=10), and negative traction test (100%, n=31) were also observed. Miniaturization occurred in 100 percent (n=31) of patients, frontal/occipital hair thickness was reduced in 83.9 percent (n=26), and more than 10 percent of velus hair in the frontal area was observed in 83.9 percent (n=26) of patients. The number of hair shafts per follicular unit was reduced in 67.7 percent (n=21), and a higher frontal to occipital ratio of follicular units with one hair shaft was seen in 74.2 percent (n=23) of patients. Empty follicles, large numbers of peripillar brownish halo, scalp pigmentation, mild Ludwig''s baldness degree, and quality of life scores of 4±3.5 points were observed. CONCLUSION: Our results indicate that patient satisfaction and quality of life of women with AGA on 5% topical minoxidil are high, although hair loss influences daily habits and social life.     

Variability in cesarean delivery rates among individual labor and delivery nurses compared to physicians at three attribution time points

ObjectiveTo examine the variability in the cesarean delivery (CD) rates of individual labor and delivery nurses compared with physicians at three attribution time points.Data SourcesMedical record data from nine hospitals in Washington State from January 2016 through September 2018.Study DesignRetrospective, observational cohort design using an aggregated database of birth records.Data Collection/Extraction MethodsChart‐abstracted clinical data from a subset of nulliparous, term, singleton, vertex births attributed at admission, labor management, and delivery to nurses and physicians. Two classification methods were used to categorize nurse‐ and physician‐level CD rates at three attribution time points and the reliability of these methods compared.Principal FindingsThe sample included 12 556 births, 319 nurses, and 126 physicians. Overall, variation in nurse‐level CD rates did not differ significantly across the three attribution time points, and the extent of variation was similar to that observed in physicians. However, agreement between attribution time points varied between 35 percent and 65 percent when classifying individual nurses into the top and bottom deciles. The average reliability of nurse‐level CD rates was 32 percent at admission (IQR 22.0 percent to 38.7 percent), 32.6 percent at labor (IQR 23.1 percent to 40.9 percent), and 29.3 percent (IQR 20.9 percent to 35.8 percent) at delivery. The average reliability of physician‐level CD rates was higher: 54.2 percent (IQR 38.7 percent to 71.4 percent) at admission, 62.5 percent (IQR 49.0 percent to 79.6 percent) at labor management, and 66.1 percent (IQR 53.7 percent to 81.2 percent) at delivery.ConclusionFeedback on nurse‐level CD rates as part of routine clinical quality audits can provide insight into nurse performance in the context of other individual‐level and unit‐level information. To reliably distinguish individual nurse performance, larger sample sizes are needed.     

The association between decision-making skills and subjective decision outcomes among administrative officers in the Swedish Social Insurance Agency

Social insurance administrative officers’ decision-making skills influence their efficiency at work and their general well-being. At work their tasks are characterised by complexity and a need for order and accountability. Moreover, cases should usually be handled and finalised within the imposed time frames. We investigated skills related to decision-making success among social insurance officers. In total, 118 administrative officers at the Swedish Social Insurance Agency (66% response rate) responded to questions on scales and measures relating to cognitive-rational, socio-emotional and time approach features of decision-making skill. In addition, they responded to questions on three scales pertaining to outcomes of everyday decisions in terms of subjective everyday difficulties, tendencies to burnout and depressive symptoms. The results showed that cognitive-rational competence was associated with lower reports of subjective everyday difficulties and depressive symptoms and thereby contributed to the explained variance in decision outcomes. Furthermore, socio-emotional and time approach features of decision-making skills contributed to the explanation for subjective everyday difficulties, tendencies to burnout and depressive symptoms. The results corroborate the basic assumption and usefulness of a broad approach in the definition and assessment of decision-making skills in human service professions in general, and of administrative officers in social insurance agencies in particular. Recommendations for future research and the implications of the results are discussed.     

Metaphase quality can be monitored by automatic counting of bands

A high quality of cytogenetic preparations is important for maintaining a high standard in the cytogenetic laboratory. In the past, quality has been assessed by visual counting or estimation of the number of bands on chromosomes. In this paper we have counted bands automatically during karyotyping by using the Magiscan chromosome analysis system. A high correlation between automatic and visual counting was found, the automatic counting was reproducible and count figures were comparable when the karyotyping machines were operated by different technicians. The automatic counting procedure has now been included in our routine for 1 year. The highest numbers of bands were counted on slides from peripheral blood, with fewer bands for amniotic fluid and the lowest number for cells from chorionic villi. All three cell types showed significant variations in band number over time, which may be due to changes in weather conditions and/or the reagents used for cell culture, harvest and staining. It is concluded that the automatic counting procedure may be used to monitor the quality of metaphases over time and to set limits for band number on routine preparations acceptale for analysis.     

Simulation of time-resolved breast transillumination

A Monte Carlo simulation has been developed to predict the quality of time-resolved images of the breast by transillumination. The smallest diameter of a detectable carcinoma located in the breast has been computed. The simulation suggests that time-resolved imaging of the breast is possible and invaluable in the near infra-red (NIR) by transillumination. The enhancement of the transfer function by the introduction of time-resolved detection is limited by the contribution of noise at short integration times. The estimated diameter of the smallest detectable sphere is derived from the image quality index (IQI) theory and its value is around 4 mm. The simulated images of an absorbing sphere (approximating the carcinoma) within a homogeneous medium (approximating the surrounding tissue) show a significant improvement of the image with short integration time.     

Allergy to pine nuts in a bird fancier

A patient is described with the bird-egg syndrome who experienced an anaphylactic reaction after eating some of her parrot's food (pine nuts: Pinus pinea ). Specific IgE against this nut and another pine nut ( P cembra ) was demonstrated by RAST. Cross-reactivity between these botanically related seeds was shown by RAST inhibition. Besides avian antigens, bird food antigens should be taken into consideration when symptoms of allergy occur on exposure to birds.
