Role of Google Glass in improving patient satisfaction for otolaryngology residents: a pilot study.

OBJECTIVES: To demonstrate the feasibility and efficacy of the Google Glass as a tool to improve patient satisfaction and patient-physician communication for otolaryngology residents in the outpatient clinic setting. The primary outcome of the study was to improve patient satisfaction scores based on physician communication-related questions from Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys. STUDY DESIGN: Prospective randomised trial. SETTING: Tertiary care hospital. SUBJECT AND METHODS: To evaluate the effect on patient satisfaction, five residents were recorded using the Google Glass in an outpatient clinic setting by 50 randomised patients. Modified surveys based on the CG-CAHPS survey were completed by patients at the conclusion of each clinic encounter. The recorded videos were evaluated by two independent faculties. Summarised data and video were distributed to each resident for review as the intervention. The residents were recorded again by 45 additional patients with evaluation by patients and faculties. RESULTS: After intervention, the scores from faculty surveys regarding patient satisfaction including the subject of better explanations (P > 0.001), listening carefully (P > 0.001), addressing patient questions (P > 0.001), displaying respect (P > 0.001) and spending adequate time (P = 0.0005) all significantly improved, as well as overall performance (P = 0.014). The scores from patient surveys did significantly improve. CONCLUSION: This study demonstrates the improvements in patient satisfaction and patient-physician communication can be achieved with the use of Google Glass as a first-person recording device in the outpatient otolaryngology clinic setting.

Effects of probiotics on atopic dermatitis: a randomised controlled trial.

BACKGROUND: The aim of the study was to investigate the effects of probiotics on moderate or severe atopic dermatitis (AD) in young children. METHODS: Fifty six children aged 6-18 months with moderate or severe AD were recruited into a randomised double blind placebo controlled trial in Perth, Western Australia; 53 children completed the study. The children were given a probiotic (1x10(9)Lactobacillus fermentum VRI-033 PCC; Probiomics) or an equivalent volume of placebo, twice daily for 8 weeks. A final assessment at 16 weeks was performed. RESULTS: The main outcome measures were severity and extent of AD at the end of the study, as measured by the Severity Scoring of Atopic Dermatitis (SCORAD) index. The reduction in the SCORAD index over time was significant in the probiotic group (p = 0.03) but not the placebo group. Significantly more children receiving probiotics (n = 24, 92%) had a SCORAD index that was better than baseline at week 16 compared with the placebo group (n = 17, 63%) (p = 0.01). At the completion of the study more children in the probiotic group had mild AD (n = 14, 54%) compared to the placebo group (n = 8, 30%). CONCLUSION: Supplementation with probiotic L fermentum VRI-003 PCC is beneficial in improving the extent and severity of AD in young children with moderate or severe disease.

Characteristics and outcome of t(8;21)-positive childhood acute myeloid leukemia: a single institution's experience.

To elucidate the clinical and biological features of childhood acute myeloid leukemia (AML) with the t(8;21), we reviewed the records of patients with AML treated at St Jude Children's Research Hospital over a 17-year period (1980 to 1996). Of 298 patients with AML, 40 (13%) had blast cells that contained the t(8;21). This translocation was associated with a high frequency of French-American-British M2 morphology (82%) and the presence of granulocytic sarcoma (23%). Molecular analysis detected the AML1-ETO fusion transcript in all 25 cases with the t(8;21) tested, but failed to identify additional cases with AML1-ETO among the 127 cases with other cytogenetic findings. Compared to patients with other genetic abnormalities, those with the t(8;21) were less likely to have internal tandem duplications of the FLT3 gene (none of 10 vs 16 of 68). The 6-year overall survival estimate was 55% +/- 9% and the event-free survival estimate, 33% +/- 7%. Of the clinical and biological features examined, only gender was prognostically significant: the 6-year overall survival estimate for males was 68% +/- 10%, compared to 33% +/- 11 for female patients (P = 0.03). Treatment outcome was not influenced by the chemotherapy regimen used or by the use of autologous hematopoietic stem cell transplantation. These results suggest that t(8;21)-positive AML represents a heterogeneous disease with variable outcome. The reported favorable outcome for t(8;21)-positive AML in other studies may be due to the use of high-dose cytarabine.

Yellow nail syndrome presenting as non-immune hydrops: second case report.

The yellow nail syndrome is characterized by slowly growing yellow discolored nails and lymphoedema, with onset generally after puberty. We report on a newborn infant who, at 23 weeks, was found to have hydrops on antenatal ultrasonography and bilateral chylothorax at delivery. His mother has the yellow nail syndrome, with typical nail changes, and bronchiectasis. There seemed to be no other etiology for the non-immune hydrops, and this is the second documented case of the prenatal manifestation of this condition.

Fixed drug eruptions in children.

To determine the anatomic location and offending drug in fixed drug eruptions (FDE) in children, we performed a 5-year retrospective analysis. Thirty-five children with FDE were evaluated. The most common cause of FDE was the combination drug trimethoprim-sulfamethoxazole.

Cytogenetic analysis of a scapular chondromyxoid fibroma.

Chondromyxoid fibroma (CMF) is a rare cartilaginous tumor of bone. It typically presents in the lower extremities of young males. Cytogenetic analysis of two chondromyxoid fibromas has been previously reported. We studied a scapular CMF from an 11-year-old female by cytogenetic and molecular cytogenetic methods and found an unbalanced reciprocal translocation between the short arm of chromosome 3 and the long arm of chromosome 6. In this translocation, several bands from chromosome 3 (3p12, 3p13, 3p14, 3p21) are lost and several bands on chromosome 6 (6q21, 6q22, 6q23) appear rearranged. Two known cartilage-related genes are located in the regions affected by this unbalanced rearrangement: the type X collagen gene (COL10A1) located at 6q21-q22 and the parathyroid hormone/parathyroid hormone-related peptide receptor gene (PTH/PTHrP) located at 3p21.1-p22. These genes function to control growth and maturation of endochondral bone, the site of origin of cartilaginous tumors.

Juvenile dermatomyositis.

Juvenile dermatomyositis (JDMS) is a chronic inflammatory condition characterized by muscle weakness and a distinctive rash caused by underlying vasculopathy. Long-term complications include subcutaneous and muscular calcification, contractures and in some cases the gradual development of a second connective tissue disease. Early aggressive treatment with systemic immunosuppressants and other agents such as intravenous immunoglobulin (IVIG) reduces mortality and morbidity.

Atopic dermatitis: is it an allergic disease?

For many years controversy has surrounded the relation between allergy and atopic dermatitis. We critically review the evidence for the contribution of allergy, or IgE-mediated hypersensitivity reactions, to the pathogenesis of this disease. We conclude that, at present, there is scant evidence that allergy is central to the development of atopic dermatitis, although it may be an aggravating factor in a few patients. Hence there is little rationale for the routine use of allergy testing or dietary and environmental manipulation in the management of this disease.

Discoid lupus erythematosus.

Discoid lupus erythematosus is a manifestation of chronic cutaneous lupus erythematosus with a small risk of systemic involvement. In this review article, the role of predisposing factors such as haplotype, hormones, antibodies and sunlight are discussed. The clinical features, including variants and associations, and management options are presented.

Prognosis of occupational chromate dermatitis.

To elucidate further the natural history and prognosis of occupational chromate dermatitis, 120 affected patients, diagnosed between 1980 and 1989, were reviewed. The incidence of chromate dermatitis in Western Australia appeared to remain unchanged over the decade. 65% of patients were construction workers with cement-induced chromate dermatitis. Workers at greatest risk of sensitization were those mixing bagged cement at the work site. The median age at onset of symptoms was 34 years, with 48% having been exposed to chromate for 5 years or less. Only 37% presented to the dermatologist within 12 months of developing symptoms. 76% of patients had ongoing dermatitis at the time of review. Although 48% of the study population had completely changed their occupation to avoid chromate exposure, symptoms persisted in 69%. A delayed diagnosis of chromate sensitivity was noted to be a predictor of chronicity. In view of the potential chronicity of chromate dermatitis and its associated social and occupational impairment, we recommend the addition of ferrous sulphate while mixing bagged cement at the work site. This simple technique targets the workers at greatest risk of becoming sensitized.

The effect of bacterial colonization on venous ulcer healing.

To determine the effect of bacterial colonization on venous ulcer healing, 82 patients with 100 venous ulcerated limbs were each studied prospectively for six months. Despite bacteriological swab results, topical or systemic antibiotics were not administered unless cellulitis supervened. Initial ulcer size, length of ulcer history and time to complete healing of colonized and uncolonized ulcers were determined and compared. Organisms were cultured from 83 limbs prior to commencement of treatment, the commonest isolates being Staphylococcus aureaus (48%), mixed coliforms (28%), Pseudomonas aeruginosa (21%) and anaerobes (17%). When compared with ulcers with no bacterial growth, colonized ulcers were of longer duration (p [symbol: see text] 0.01), had a larger initial size (p [symbol: see text] 0.001) and had significantly longer healing time (p [symbol: see text] 0.001). When analysed individually beta-haemolytic streptococci, anaerobes, Staphylococcus aureus and coliforms were associated with delayed healing. Delayed healing was not found with Pseudomonas aeruginosa, although pseudomonas-colonized ulcers were significantly larger and of longer duration than uncolonized ulcers. Bacterial colonization is associated with delayed venous ulcer healing. To further clarify the pathogenicity of colonizing bacteria, however, the effect of their eradiction on healing of venous ulcers needs to be established.
