Dermatology Life Quality Index survey in patients with Down syndrome and caregivers.

Down syndrome (DS) is associated with many dermatological conditions, including hidradenitis suppurativa, folliculitis, and alopecia areata. Despite the high incidence of skin conditions in this population, there are no quality of life (QoL) studies in the dermatology literature focused on patients with DS or their caregivers. The frequently used QoL assessment tool, the Dermatology Life Quality Index (DLQI), has yet to be studied in this population. This study addresses these disparities by capturing how various skin conditions affect the QoL of people with DS and their caregivers and assessing the utility of the DLQI.

Predicting the number of physical therapy visits and patient satisfaction in individuals with temporomandibular disorder: A cohort study.

BACKGROUND: Temporomandibular disorders (TMD) can be challenging to manage for clinicians and patients alike. It is unclear which factors are associated with prolonging conservative care and patient dissatisfaction with treatment outcomes. OBJECTIVES: To examine factors collected during a physical therapy (PT) evaluation in a cohort of individuals with TMD to determine factors associated with an increased number of PT visits and reduced patient satisfaction. METHODS: Records of 511 patients referred to PT over 18 months were reviewed to extract 27 variables to develop a predictive model. Outcomes were patient satisfaction following PT and number of PT visits. Linear and zero inflated negative binomial regressions were used, and a multivariate regression model was built for both outcomes. RESULTS: Two factors were associated with both lower patient satisfaction and an increased number of PT visits: higher patient rated functional neck disability and a greater number of healthcare professionals seen. Other factors associated with patient satisfaction were duration of symptoms, subluxation, and referral from an oral surgeon. Only patient rated functional neck disability score was a significant predictive factor in the multivariate model. Factors associated with number of PT visits were gender, educational level, time between initial visit and discharge, number of pain areas, bruxism, biopsychosocial factors, dizziness, pain rating, and presence of neck pain. In the multivariate model, gender, number of healthcare professionals seen, and resting pain rating were significant predictors of number of PT visits. CONCLUSION: Considering key factors on initial evaluation, specifically functional neck disability and the number of prior healthcare professionals seen before starting PT, can help to predict a higher number of PT visits and reduced patient satisfaction with outcomes.

Risk Factors Associated With Nephrotoxicity During Outpatient Intravenous Vancomycin Administration.

Background: Many studies have described an association between intravenous vancomycin and nephrotoxicity; however, the majority have evaluated incidence and risk factors among hospitalized patients. Outpatient administration of intravenous antibiotics is a growing practice and presents its own set of unique challenges. Objective: The aim of this study was to identify risk factors for vancomycin-associated nephrotoxicity in the outpatient setting. Methods: A case-control study of patients who received intravenous vancomycin through an Outpatient Parenteral Antimicrobial Therapy (OPAT) program was conducted. Patients were identified who developed an acute kidney injury (AKI) during treatment. The primary outcome was the incidence of AKI during treatment. Results: A total of 37 out of 130 patients (28.5%) met the criteria for AKI. AKI was more likely to occur in patients with a longer duration of therapy, higher maximum trough concentration, co-administration of a fluoroquinolone or metronidazole, and those who received another potentially nephrotoxic medication. Co-administration of a fluoroquinolone (OR = 5.96, P = 0.009, [CI: 1.59, 24.38]), any nephrotoxic medication (OR = 11.17, P < 0.001, [CI 3.14, 51.23]), and a higher maximum vancomycin trough (OR = 1.29, P < 0.001, [CI 1.17, 1.44]) were all indicative of a higher odds of an AKI. Conclusion: In this cohort, vancomycin-associated nephrotoxicity was common during outpatient intravenous antibiotic therapy. Co-administration of a fluoroquinolone, any nephrotoxic medication, and a higher maximum vancomycin trough were associated with AKI development. Further study is needed to determine how this impacts long-term clinical outcomes and what measures can be taken to reduce nephrotoxicity risk.

Lumbar multifidus muscle ultrasound imaging: Is handheld technology reliable?

BACKGROUND: Advancement in ultrasound imaging technology has led to the development of handheld devices that are more accessible to physical therapists due to decreased cost, reduced size, and improved ease of use relative to current established units. Physical therapists use ultrasound imaging of the lumbar multifidus muscle (LMM) to assist in rehabilitation of patients with lumbar pathology. OBJECTIVES: To identify the inter-device reliability of measuring the LMM thickness during a sustained contraction when comparing handheld (Butterfly iQ+) and established (SonoSite M-Turbo) ultrasound units. A secondary purpose was to determine the reliability of a student physical therapist using both devices. DESIGN: A reliability measurement study METHOD: A blinded examiner identified the LMM at the L4 vertebral level and measured the thickness of the contracted muscle utilizing both the handheld and established ultrasound devices. ICC values were calculated to determine the inter-device and intra-rater reliability. RESULTS: The study included 42 healthy participants, 30 females and 12 males, with a mean age of 38.5 years. The inter-device reliability during a sustained LMM contraction was excellent (ICC = 0.92, 95% CI: 0.87-0.94) and the intra-rater reliability was good for both the handheld (ICC = 0.85, 95% CI: 0.73-0.92) and established (ICC = 0.89, 95% CI: 0.82-0.93) ultrasound units. CONCLUSION: Results support the use of handheld ultrasound by physical therapists and students to measure the LMM thickness. Future studies could investigate the reliability of handheld ultrasound in a variety of musculoskeletal and pathological structures important to PT practice.

Estimating relative CWD susceptibility and disease progression in farmed white-tailed deer with rare PRNP alleles.

Chronic wasting disease is a prion disease affecting both free-ranging and farmed cervids in North America and Scandinavia. A range of cervid species have been found to be susceptible, each with variations in the gene for the normal prion protein, PRNP, reportedly influencing both disease susceptibility and progression in the respective hosts. Despite the finding of several different PRNP alleles in white-tailed deer, the majority of past research has focused on two of the more common alleles identified-the 96G and 96S alleles. In the present study, we evaluate both infection status and disease stage in nearly 2100 farmed deer depopulated in the United States and Canada, including 714 CWD-positive deer and correlate our findings with PRNP genotype, including the more rare 95H, 116G, and 226K alleles. We found significant differences in either likelihood of being found infected or disease stage (and in many cases both) at the time of depopulation in all genotypes present, relative to the most common 96GG genotype. Despite high prevalence in many of the herds examined, infection was not found in several of the reported genotypes. These findings suggest that additional research is necessary to more properly define the role that these genotypes may play in managing CWD in both farmed and free-ranging white-tailed deer, with consideration for factors including relative fitness levels, incubation periods, and the kinetics of shedding in animals with these rare genotypes.
