Impact of disease severity on work productivity and activity impairment in Japanese patients with atopic dermatitis

Atopic dermatitis (AD) is a common inflammatory skin disease that is characterized by chronic and persisting pruritic and eczematous lesions. There has been no study of work productivity and activity in AD patients in relation to disease severity. The purpose of this study was to examine the impact of disease severity on work productivity and activity impairment (WPAI) in adult AD patients using the Japanese version of the questionnaire. Data were collected from 112 AD patients who visited the Jikei University Hospital. Outcomes as measured by the questionnaire included employment status, total work productivity impairment (TWPI) and total activity impairment (TAI). We investigated the correlation between TWPI or TAI scores and severity scoring of AD (SCORAD) for disease severity and dermatology life quality index (DLQI) for quality of life impairment. Both TWPI and TAI scores were significantly correlated with the SCORAD and DLQI scores (P < 0.001), indicating disease severity is significantly associated with WPAI in Japanese adult AD patients. Further studies are necessary to evaluate the effects of treatments on WPAI for severe AD patients.     

The Malawi trauma score: A model for predicting trauma-associated mortality in a resource-poor setting

BackgroundGlobally, traumatic injury is a leading cause of morbidity and mortality in low-income countries. Current tools for predicting trauma-associated mortality are often not applicable in low-resource environments due to a lack of diagnostic adjuncts. This study sought to derive and validate a model for predicting mortality that requires only a history and physical exam.MethodsWe conducted a retrospective analysis of all patients recorded in the Kamuzu Central Hospital trauma surveillance registry in Lilongwe, Malawi from 2011 through 2014. Using statistical randomization, 80% of patients were used for derivation and 20% were used for validation. Logistic regression modeling was used to derive factors associated with mortality and the Malawi Trauma Score (MTS) was constructed. The model fitness was tested.Results62,354 patients are included. Patients are young (mean age 23.0, SD 15.9 years) with a male preponderance (72%). Overall mortality is 1.8%. The MTS is tabulated based on initial mental status (alert, responds to voice, responds only to pain or worse), anatomical location of the most severe injury, the presence or absence of a radial pulse on examination, age, and sex. The score range is 2–32. A mental status exam of only responding to pain or worse, head injury, the absence of a radial pulse, extremes of age, and male sex all conferred a higher probability of mortality. The ROC area under the curve for the derivation cohort and validation cohort were 0.83 (95% CI 0.78, 0.87) and 0.83 (95% CI 0.75, 0.92), respectively. A MTS of 25 confers a 50% probability of death.ConclusionsThe MTS provides a reliable tool for trauma triage in sub-Saharan Africa and helps risk stratify patient populations. Unlike other models previously developed, its strength is its utility in virtually any environment, while reliably predicting injury- associated mortality.     

SAPS 3 is not superior to SAPS 2 in cardiac surgery patients

Objectives. Cardiac surgery patients are excluded from SAPS2 but included in SAPS3. Neither score is evaluated for this exclusive population; however, they are used daily. We hypothesized that SAPS3 may be superior to SAPS2 in outcome prediction in cardiac surgery patients. Design. All consecutive patients undergoing cardiac surgery between January 2007 and December 2010 were included in our prospective study. Both models were tested with calibration and discrimination statistics. We compared the AUC of the ROC curves by DeLong's method and calculated OCC values. Results. A total of 5207 patients with mean age of 67.2 ± 10.9 years were admitted to the ICU. The mean length of ICU stay was 4.6 ± 7.0 days and the ICU mortality was 5.9%. The two tested models had acceptable discriminatory power (AUC: SAPS2: 0.777–0.875; SAPS3: 0.757–893). SAPS3 had a low AUC and poor calibration on admission day. SAPS2 had poor calibration on Days 1–6 and 8. Conclusions. Despite including cardiac surgery patients, SAPS3 was not superior to SAPS2 in our analysis. In this large cohort of ICU cardiac surgery patients, performance of both SAPS models was generally poor. In this subset of patients, neither scoring system is recommended.     

Retrospective analysis of clinical outcomes in bilateral cleft lip and palate patients after secondary alveolar bone grafting and premaxilla osteotomy,using a new dento-maxillary scoring system

Evaluation of relevant clinical outcomes in patients with bilateral cleft lip and palate (BCLP) after secondary aveolar bone grafting (SABG) and premaxilla osteotomy (PMO), through the use of a new scoring system.Data were collected retrospectively from all patients with BCLP who were operated on between 2004 and 2014, at the end of follow-up. The treatment protocol consisted of SABG + PMO in patients aged between 9 and 13 years. At the end of follow-up, the following parameters were scored: (un)interrupted dental arch, skeletal sagittal relationship, bone height using the Bergland/Abyholm criteria, and the presence of postoperative fistula. These parameters were combined to produce a dento-maxillary scoring system, giving a final score between 1 and 10. For statistical analysis, the independent t-test was used.Of 55 children, 45 were suitable for analysis. The mean age at time of surgery was 12.0 years (8.9–16.4 yrs), and the mean follow-up time was 11.7 years (5.8–15.8 yrs). The average number of surgeries executed under general anesthesia was 6 (range: 3–11). The average dento-maxillary score in this patient cohort was 7.6 (1–10; median: 8). Among these patients, 31 had an uninterrupted dental arch; the average Bergland/Abyholm score was 2.07; 30 patients exhibited an Angle class I incisor relationship; and, in 38 cases, the oronasal communication was closed after SABG + PMO treatment. A significant effect of fistulas was seen on dento-maxillary score (p = 0.001). Specifically, a significant effect of fistulas was seen on interrupted dental arch (p = 0.002) and on Bergland/Abyholm score (p = 0.037).The proposed dento-maxillary scoring system is a straightforward tool that can be used to describe and analyze the amount of dento-maxillary rehabilitation at the end of the treatment. Persistence of oronasal fistulas in patients with BCLP has a significant impact on interruption of the dental arch, and can influence dental results at the end of the second decade.     

TRACHY score: a simple and effective guide to management of the airway in head and neck cancer

Our aim was to provide a simple and effective scoring system to guide decision making in management of the airway. We retrospectively reviewed the casenotes of all patients diagnosed with head and neck cancer and who were treated by resection with primary flap reconstruction. Those factors that were significant (p< 0.05) were analysed by logistic regression to establish their weighting. A total of 149 patients were included, 67 of whom (45%) were managed with endotracheal tubes, and 82 with tracheostomy (55%), of which eight were unplanned and late. From this we produced a score based on: T (T staging), R (Reconstruction), A (Anatomy of tumour), C (Coexisting conditions), H (History of previous treatment for head and neck cancer), Y (lateralitY- bilateral neck dissection). A score of 4 gave a sensitivity of 91.4%, a positive predictive value of 90.9%, a specificity of 90.8% and a negative predictive value of 88.2%. We applied this score to the patients, and it gave a mean score of: 2.1 (intubated), 5.7 (primary tracheostomy), and 4.6 (late tracheostomy). This is the largest published study to our knowledge of tracheostomies in head and neck cancer flap reconstructions that presents a scoring system for management of the airway. This scoring system can appropriately predict those patients who do not need tracheostomy and can act as a reliable screening tool in preoperative planning of the airway. It could aid management, and reduce the incidence of postoperative tracheostomies, with the potential that patients could be managed more safely, with reduced morbidity and mortality.

A method to score radiographic change in psoriatic arthritis

INTRODUCTION: Radiographic features of psoriatic arthritis (PsA) are very characteristic and differ from those observed in rheumatoid arthritis, especially in two aspects: 1) the distribution of affected joints (i.e. DIP joints), 2) the presence of destructive changes and bone proliferation at the same time. A scoring method for PsA, therefore, has to account for these characteristics of PsA. OBJECTIVE: To develop, describe and validate a method for scoring radiographic changes in patients with PsA. DESCRIPTION OF THE METHOD: Forty joints of the hands and feet are scored for destruction and proliferation. In the destruction score (DS) grading on a 0-5 scale is based on the amount of joint surface destruction: 0 = normal, 1 = one or more erosions with an interruption of the cortical plate of > 1 mm with destruction of the total joint surface up to 10%, 2 = 11-25%, 3 = 26-50%, 4 = 51-75%, 5 = > 75% joint surface destruction. The proliferation score (PS) sums up any kind of bony proliferation typical for PsA; graded 0-4: 0 = normal, 1 = bony proliferation of 1-2 mm or bone growth < 25% of the original size (diameter), 2 = bony proliferation 2-3 mm or bone growth 25-50%, 3 = bony proliferation > 3 mm or bone growth > 50%, 4 = bony ankylosis. The DS (0-200) and the PS (0-160) can be summed up to the total score (0-360). VALIDATION OF THE METHOD: To validate the method x-rays of 20 patients with active PsA taken 3 years apart were read twice in pairs, knowing the chronological order but not knowing demographic, clinical or laboratory data of the patients. The data were analyzed with a hierarchical analysis of variance model. RESULTS: There was good agreement between the first and the second reading of the same rater and between the two raters regarding the destruction score. The agreement regarding the proliferation score was lower but still acceptable. The reliability of the method to describe change over time--relation of progression (intra-patient variance) to the measurement error (inter-rater variance)--was 3.9 for the DS, 2.8 for the PS and 4.1 for the total score. The minimal detectable change when the readings of two raters were compared (inter-rater MDC) was 5.8, 5.0 and 4.6%, respectively of the maximum possible score for the destruction, the proliferation and the total score. These data compare very well with the results of standard scoring methods in rheumatoid arthritis. CONCLUSION: We propose a method for scoring radiographic change in psoriatic arthritis which reliably quantifies the progression of the disease seen on radiographs.
