Atopic dermatitis is a common condition of great health significance. Consensus-driven guidelines of care or specific practice parameters may be useful, as are treatment algorithms based upon disease severity. Development of consensus guidelines on diagnosis and treatment of atopic dermatitis are discussed, and disease-severity-based guidelines of care proposed.
Portal hypertension leads to a wide variety of complications, which lead to significant morbidity and mortality and are some of the leading reasons for liver transplantation in children with chronic liver disease. Evidence-based approaches to the management of adults with portal hypertension exist and have been comprehensively reviewed in a series of international meetings, including the Baveno meetings. Similar evidence-based approaches for the management of portal hypertension in children do not exist and as such international meetings on portal hypertension have not focused on this problem in children. On October 7, 2005 at The Mount Sinai School of Medicine, a panel of pediatric experts reviewed the most recent Baveno statement and crafted a statement modified with their opinions vis a vis approaches to the management of portal hypertension in children.
The recent introduction of the meso Rex bypass raises a possible paradigm shift in the therapeutic approach to extra-hepatic portal vein obstruction (EHPVO). Long-term follow-up of patients with EHPVO has revealed a variety of complications including variceal hemorrhage, hypersplenism, biliopathy, growth/development retardation and neuropsychiatric disease. The meso Rex bypass restores physiologic blood flow to the liver. Thus, when feasible, the meso Rex bypass should be considered in patients with clinically significant manifestations of EHPVO. The opinions of a panel of experts regarding the surgical approach to the management of EHPVO are presented.
Although hemovigilance is not a word used commonly in the United States, the concept of monitoring morbidity associated with blood transfusion is accepted widely. Currently, quality management focuses on error avoidance rather than error detection in both the "manufacturing" and "clinical" aspects of blood banking. "Manufacturing" is regulated predominantly by current Good Manufacturing Practices while clinical transfusion medicine follows clinical practice guidelines. There are multiple overlapping mechanisms for quality assurance and error reporting among governmental, professional, and non-profit regulatory agencies. The strategies of each stress the on-going need for a systems approaches to preventing errors.
There is an increasing use of 3-D conformal radiotherapy (3DCRT) in the radiotherapeutic management of prostate cancer. The Faculty of Radiation Oncology Genito-Urinary Group carried out a survey of Australian and New Zealand radiotherapy centres in the preparation of a consensus workshop. Of the 19 centres that were represented, there were 24 radiation oncologists, 16 radiation therapists and 12 medical physicists. The survey collected demographic information and data on the practices undertaken at those centres when delivering curative radiotherapy in the treatment of prostate cancer. There was much variation in the delivery of treatment in the areas of patient set-up, contouring of target volumes and organs of interest during computer planning, the techniques and the dose constraints used in these techniques, the use of adjuvant androgen deprivation therapy and the quality assurance processes used in monitoring effects of treatment. This variability reflects the range of data in the published literature. Emerging trends of practices were also identified. This is a first report on a multi-disciplinary approach to the development of guidelines in 3DCRT of prostate cancer.

BACKGROUND AND AIM: In 1999, a group of Western and Asian pathologists gathered in Vienna reached consensus regarding the classification of gastrointestinal epithelial neoplasia. In this study, that classification is applied to colorectal adenomas. METHODS: Colorectal adenomas from 1552 patients were histologically classified according to the categories listed in Vienna: category 3, low-grade dysplasia; 4.1, high-grade dysplasia; 4.2, carcinoma in situ; 4.3, suspicious of intramucosal carcinoma; 5.1, intramucosal carcinoma; and 5.2, submucosal carcinoma. The criteria used to diagnose these lesions are described in detail. Adenomas with dysplasia (categories 3 and 4.1) or with carcinoma (categories 4.2, 4.3, 5.1 and 5.2) were analyzed separately. On basis of their configuration, adenomas were classified into tubular, tubulovillous, villous, serrated, microtubular and combined phenotypes (i.e. other than tubulovillous). RESULTS: The highest percentage of adenomas with carcinoma was found amongst villous adenomas (29.6%), followed by combined adenomas (27.8%). Villous adenoma with carcinoma was the most frequent neoplasia at all ages; combined adenomas with carcinoma were more frequent among younger patients. In elderly patients (> or = 60 years of age) the highest percentage of adenomas with carcinoma was recorded in villous adenomas (28.1%), followed by serrated adenomas (19.2%). Villous adenomas and combined adenomas with carcinoma were more frequent in males. CONCLUSION: The Vienna classification of colorectal adenomas seems to be influenced by parameters inherent to the patient such as age and sex and by the histological phenotype of the adenoma. With the recent improvement in medical technology it is possible to laser-microdissect a defined group of neoplastic glands (such as with carcinoma in situ or with intramucosal carcinoma) for specific molecular analysis. This modern technology will permit in future the translation of histological structures into molecular terms.

The National Health and Medical Research Council National Breast Cancer Centre was established to improve outcomes for women by reviewing the literature, developing best practice guidelines and resources and developing a national monitoring system. Its broad terms of reference meant that it was important at the outset to identify priorities for action. The Centre used a national consultative process based on nominal groups to identify priorities. Thirteen consultative workshops were held with over 300 participants including women diagnosed with breast cancer, some of their families and health professionals. There was a high level of agreement between workshops in priorities identified, indicating that the nominal group process results in reliable data. A sub-sample of participants surveyed after the workshops reported being highly satisfied with their participation in the process. The findings indicate that the nominal group process can be useful in selecting priorities for action in health.

OBJECTIVE: On the eight scales of the Medical Outcomes Study Short-Form 36-Item Health Survey (SF-36), Version 2, we compared the clinically important difference (CID) thresholds for change over time developed by three separate expert panels of physicians with experience in quality of life assessment among patients with chronic obstructive pulmonary disease (COPD), asthma, and heart disease. STUDY DESIGN: We used a modified Delphi technique combined with a face-to-face panel meeting within each disease to organize and conduct the consensus process among the expert panelists, who were familiar with the assessment and evaluations of health-related quality of life (HRQL) measures among patients with the panel-specific disease. PRINCIPAL FINDINGS: Each of the expert panels first determined the magnitude of the smallest numerically possible change on each SF-36 scale, referred to as a state change, and then built their CIDs from this metric. All three panels attained consensus on the scale changes that constituted small, moderate, and large clinically important SF-36 change scores. The CIDs established by the heart disease panel were generally greater than the CIDs agreed on by the asthma and COPD panels. CONCLUSIONS: These panel-derived thresholds reflect possible differences in disease management among the represented panel-specific diseases, and are all greater than the minimal CID thresholds previously developed for the SF-36 scales among patients with arthritis. If confirmed among patients with the relevant diseases and those patients' physicians, these disease-specific CIDs could assist both researchers and practicing clinicians in the use and interpretation of HRQL changes over time.

OBJECTIVE: To facilitate the diagnostic process for dementia. Five guidelines and four consensus statements on specific diagnostic recommendations, specialist referral recommendations, and costs of recommended diagnostic procedures were compared and summarized. DATA SOURCES AND SELECTION: A MEDLINE search from 1984 to 1999 and queries to experts yielded 14 guidelines and consensus statements that addressed the diagnosis of dementia. Only nine documents which had national or international scopes were reviewed. METHODS: Comparisons were made on the specific diagnostic criteria for patient history, clinical examination, functional assessment, laboratory tests, neuroimaging, and other diagnostic tests, as well as specialist referral recommendations and costs for the recommended diagnostic procedures. The first three authors reviewed independently each document and completed a table on specific recommendations in each document. To settle disagreements about specific recommendations, they discussed them until they reached a consensus. To interpret the intent of vague statements, they used their best judgment. RESULTS: The documents differed in content, recommendations, and development methodology. They were based on either expert opinion or scientific evidence, or both. Although the nine documents were nearly unanimous in several recommendations, including assessing the presenting problem, taking a medical history, conducting physical and neurological examinations, and assessing the patient's mental and cognitive status, considerable differences in recommendations were common. Such differences led to large differentials in the estimated costs (range, $190 to $2,001) for recommended diagnostic assessments. CONCLUSIONS: A systematic approach to diagnostic recommendations for dementia may induce greater consistency among guidelines and consensus statements. The current approach leads to considerable variability in recommendations and estimated costs.
