RESUMEN
BACKGROUND: The lack of validated and responsive outcome measures in the management of frontal fibrosing alopecia (FFA) significantly limits assessment of disease progression and treatment response over time. AIM: To understand how FFA extent and progression is currently assessed in UK specialist centres, to validate components of the International FFA Cooperative Group (IFFACG) statement on FFA assessment, and to identify pragmatic advice to improve FFA management in clinic. METHODS: Consultant dermatologists with a specialist interest in hair loss (n = 17) were invited to take part. Preferred FFA assessment methods were explored using questionnaires and clinical scenarios. Participants were asked to identify and mark the current hairline in 10 frontal and 10 temporal hairline images (Questionnaire 1), with assessment repeated 3 months later to assess intraindividual variability (Questionnaire 2) and 12 months later to test whether interindividual accuracy could be improved with simple instruction (Questionnaire 3). RESULTS: All 17 clinicians (100%) completed the questionnaire at each time interval. We identified a wide variation in assessment techniques used by our experts. Measurements were perceived as the most accurate method of assessing frontal recession whereas photography was preferred for temporal recession. Inter-rater reliability between clinicians measuring the frontal hairline scenarios indicated a moderate strength of agreement [intraclass coefficient (ICC) = 0.61; 95% CI 0.40-0.85], yet intrarater reliability was found to be poor with wide limits of agreement (-8.71 mm to 9.92 mm) on follow-up. Importantly, when clear guidance was provided on how the hairline should be identified (Questionnaire 3), inter-rater reliability improved significantly, with ICC = 0.70, suggesting moderate agreement (95% CI 0.51-0.89; P < 0.001). A similar pattern was seen with temporal hairline measurements, which again improved in accuracy with instruction. CONCLUSION: We found that accuracy of measurements in FFA can be improved with simple instruction and we have validated components of the IFFACG measurement recommendations.

BACKGROUND: Hair and scalp problems are common. Unfortunately, many uncertainties exist around the most effective management and treatment strategies for these disorders. OBJECTIVES: To identify uncertainties in hair-loss management, prevention, diagnosis and treatment that are important to both people with hair loss and healthcare professionals. METHODS: A Hair Loss Priority Setting Partnership was established between patients, their carers and relatives, and healthcare professionals to identify the most important uncertainties in hair loss. The methodology of the James Lind Alliance was followed to ensure a balanced, inclusive and transparent process. RESULTS: In total, 2747 treatment uncertainties were submitted by 912 participants; following exclusions 884 uncertainties relating to hair loss (excluding alopecia areata) were analysed. Questions were combined into 'indicative uncertainties' following a structured format. A series of ranking exercises further reduced this list to a top 25 that was taken to a final prioritization workshop where the top 10 priorities were agreed. CONCLUSIONS: We present the top 10 research priorities for hair loss (excluding alopecia areata) to guide researchers and funding bodies to support studies important to both patients and clinicians.

BACKGROUND: Alopecia areata (AA) is a common hair loss disorder that results in patchy to complete hair loss. Many uncertainties exist around the most effective treatments for this condition. OBJECTIVES: To identify uncertainties in AA management and treatment that are important to both service users (people with hair loss, carers and relatives) and healthcare professionals. METHODS: An AA priority setting partnership was established between patients, their carers and relatives, and healthcare professionals to identify the most important uncertainties in AA. The methodology of the James Lind Alliance was followed to ensure a balanced, inclusive and transparent process. RESULTS: In total, 2747 treatment uncertainties were submitted by 912 participants, of which 1012 uncertainties relating to AA (and variants) were analysed. Questions were combined into 'indicative uncertainties' following a structured format. A series of ranking exercises further reduced this list to a top 25 that were taken to a final prioritization workshop where the top 10 priorities were agreed. CONCLUSIONS: We present the top 10 research priorities for AA to guide researchers and funding bodies to support studies important to both patients and clinicians.

Alopecia and other hair abnormalities occurring in patients with psoriasis were first recognized over four decades ago, yet psoriatic alopecia is not a well-known concept among clinicians. Alopecia may be directly related to the psoriasis itself, and can affect both the scalp and other parts of the body. On the scalp, psoriatic alopecia most commonly affects lesional skin, but may present as a generalized telogen effluvium. In most cases, there is regrowth of hair, but in rare cases it can cause scarring alopecia. Histological findings include features of psoriasis in the interfollicular epithelium, along with perifollicular inflammation and atrophy or loss of the sebaceous glands. Late changes include destruction of the hair follicle, with perifollicular fibrosis and 'naked' hair shafts lying free in the dermis. In addition to the hair loss caused by the psoriasis itself, data from population and genetic studies reveal that patients with psoriasis are at greater risk of developing alopecia areata. Psoriasis treatments may also contribute to hair loss. Application of topical preparations may cause hair loss through friction, and many of the systemic treatments used for psoriasis can also cause hair problems. Treatment with anti-tumour necrosis factor-α agents can precipitate de novo psoriasis and subsequent psoriatic alopecia.

OBJECTIVES: : The significance of extrahepatic bile duct dilatation on ultrasound examination in jaundiced infants is often uncertain. We wished to clarify the diagnostic and prognostic significance of the present finding in neonatal conjugated hyperbilirubinaemia. PATIENTS AND METHODS: : We retrospectively enrolled all of the infants younger than 3 months with extrahepatic biliary dilatation > or =1.2 mm (nonfasting ultrasound) who presented during the study period. We reviewed clinical, radiological, and laboratory data to determine mode of presentation, diagnosis, interventions, and long-term outcome. RESULTS: Seventy-six infants (41 male) were identified, all of whom were referred with conjugated hyperbilirubinaemia. Median gestational age was 39 weeks (range 24-42 weeks). Inspissated bile was the most common diagnostic category, whereas congenital choledochal malformation was the diagnosis made in 13% infants. Dilatation was an incidental finding in 9% of the infants. Seventeen percent of infants had required either surgical or radiological intervention by the time of follow-up. Overall, 41% infants had spontaneous resolution of bile duct dilatation, including 8% who had "grown into" an unchanged duct size rather than involution of dilatation. The median size of bile duct at presentation for those who required intervention was 4.7 versus 2 mm for the remainder (P < 0.001). Of those who resolved spontaneously, the median size of duct at presentation was 1.8 mm. CONCLUSIONS: : Bile duct dilatation <3 mm (nonfasting ultrasound) with neonatal cholestasis is unlikely to be of significance whereas >4 mm is likely to be associated with choledochal malformation or need for intervention. The intermediate group is likely to be associated with inspissated bile syndrome following resolution of which innocent biliary dilatation may persist.

BACKGROUND: The workplace assessments, direct observation of procedural skills (DOPS), mini-clinical evaluation exercise (mini-CEX) and multisource feedback (MSF, formerly known as 360 degrees appraisal), are now mandatory during dermatology specialist training in the U.K. The opinions of those undergoing such assessments in any medical specialty have rarely been sought. OBJECTIVES: To collate the experience and views of U.K. dermatology trainees on the three workplace assessments. METHOD: A questionnaire was circulated in autumn 2006 to all U.K. dermatology specialist registrars (SpRs) registered as members of the British Association of Dermatologists (n = 269). RESULTS: A total of 138 responses were received (51%). Seventeen SpRs had not experienced any of the assessments; 92 had undergone MSF, 95 DOPS and 54 mini-CEX. The total experience of the respondents amounted to a minimum of 251 DOPS, 122 MSF and 142 mini-CEX. Trainees appreciated the formative aspects of the assessments, especially feedback and training opportunities, although not all trainees reported receiving useful feedback. MSF was praised for the insights that it provides. All of the assessments were found to be time-consuming and difficult to organize. DOPS and mini-CEX carried a degree of stress and artificiality. Concerns were raised over the possibility of victimization by MSF raters. Discussion of performance in the assessments was rarely prominent in trainees' annual summative reviews. CONCLUSIONS: Trainees appreciate the formative benefits which derive from the assessments, namely feedback, reassurance of satisfactory performance and, in the case of DOPS and mini-CEX, additional one-to-one training from consultants. Some problems came to light. The issues raised will not be unique to dermatology and other specialties should take note.

The pancreas remains one of the more difficult organs to visualize but ultrasound can be successful in nearly 90% of patients. A systematic technique for identifying and delineating the pancreas is described and has been verified on over 500 patients to date. The success of the technique depends on an accurate knowledge of the vascular relations of the pancreas and on correct adjustment of the ultrasound equipment. This paper is intended to help ultrasound practitioners achieve both these ends.

There is currently a rapid rise in the variety of image recording systems and recording media available for use with ultrasound and CT scanners. We have evaluated nine different systems and ten recording media and have compared their cost, convenience and performance. The choice of system in a particular department depends upon many factors, especially the number of images recorded and the reasons for recording them. We suggest that a busy department will probably require one of the more expensive automatic devices since these are the most convenient to use and have the lowest cost per image.

Hepatic vein pulsatility correlates with the severity of disease in a range of different liver disorders. We describe a simple visual grading system for scoring hepatic vein pulsatility which does not require any on-screen measurements and which has proved reproducible in clinical practice. The system gives a six point score for the waveform pulsatility, 6 being a normal value and 1 indicating a complete lack of modulation.
