'Rainbow pattern': a dermoscopic sign of invasive melanoma.

BACKGROUND: The 'rainbow pattern' was initially described as a highly specific dermoscopic feature of Kaposi sarcoma. Since then, it has been reported in many benign and malignant cutaneous tumours, including a few malignant melanomas (MMs). AIM: To determine the frequency and presentation of this dermoscopic pattern in primary cutaneous MMs in comparison to other cutaneous tumours. METHODS: The presence of a rainbow pattern was evaluated in a sample of 1100 dermoscopic images of different melanocytic and nonmelanocytic cutaneous neoplasms. RESULTS: The rainbow pattern was observed in 23 of 245 (9.4%) MM and 44 of 855 (5.1%) non-MM neoplasms. MMs presenting this feature were generally thicker: 82.6% > 1 mm and 43.0% > 2 mm. Compared with non-MMs, rainbow pattern in MMs was more commonly focal (82.7% vs. 36.4% nonfocal, P = 0.001) and associated with > 2 dermoscopic structures associated with MM (100% vs. 9% with fewer, P = 0.001). CONCLUSION: The rainbow pattern is a dermoscopic sign that can occasionally be observed in invasive MMs. In MMs, this feature is usually associated with other dermoscopic criteria of MM and located in a focal and eccentric area, as opposed to a diffuse and isolated presentation in non-MM neoplasms.

Moderate to Severe Psoriasis in Pediatric and Young Patients: The BIOBADADERM Registry Experience. / Psoriasis moderada-grave en pacientes pediátricos y jóvenes: experiencia en el registro BIOBADADERM.

Childhood-onset psoriasis generally follows an indolent course but patients with moderate or severe disease may require systemic treatment. The aim of this study was to determine the relative proportion of children and young people aged up to 21 years with moderate to severe psoriasis in the BIOBADADERM registry and to analyze the characteristics of these patients, treatments used, and adverse events. Of the 3946 patients in the registry, 24 were aged 21 years or younger. They had mean age of 16.1 years on starting treatment. When the registry was started, they had a Psoriasis Area and Severity Index of 9.4 and 67% were being treated with a conventional systemic drug. Treatment was discontinued in 14 patients (58%) due to adverse events or a loss or lack of effectiveness. In conclusion, the BIOBADADERM registry shows that young people account for a small proportion of psoriasis patients receiving systemic treatment, and they are more likely to be treated using conventional systemic drugs.

Systematic review of pragmatic randomised control trials assessing the effectiveness of professional pharmacy services in community pharmacies.

BACKGROUND: Implementation of Professional Pharmacy Services (PPSs) requires a demonstration of the service's impact (efficacy) and its effectiveness. Several systematic reviews and randomised controlled trials (RCT) have shown the efficacy of PPSs in patient's outcomes in community pharmacy. There is, however, a need to determine the level of evidence on the effectiveness of PPSs in daily practice by means of pragmatic trials. To identify and analyse pragmatic RCTs that measure the effectiveness of PPSs in clinical, economic and humanistic outcomes in the community pharmacy setting. METHODS: A systematic search was undertaken in MEDLINE, EMBASE, the Cochrane Library and SCIELO. The search was performed on January 31, 2020. Papers were assessed against the following inclusion criteria (1) The intervention could be defined as a PPS; (2) Undertaken in a community pharmacy setting; (3) Was an original paper; (4) Reported quantitative measures of at least one health outcome indicator (ECHO model); (5) The design was considered as a pragmatic RCT, that is, it fulfilled 3 predefined attributes. External validity was analyzed with PRECIS- 2 tool. RESULTS: The search strategy retrieved 1,587 papers. A total of 12 pragmatic RCTs assessing 5 different types of PPSs were included. Nine out of the 12 papers showed positive statistically significant differences in one or more of the primary outcomes (clinical, economic or humanistic) that could be associated with the following PPS: Smoking cessation, Dispensing/Adherence service, Independent prescribing and MTM. No paper reported on cost-effectiveness outcomes. CONCLUSIONS: There is limited available evidence on the effectiveness of community-based PPS. Pragmatic RCTs to evaluate clinical, humanistic and economic outcomes of PPS are needed.

Pigmented Dermatofibrosarcoma Protuberans: Description of a pediatric case. / Dermatofibrosarcoma protuberans pigmentado: Descripción de un caso pediátrico.

INTRODUCTION: Bednar tumor is a rare low-grade sarcoma considered the pigmented variant of dermatofibrosarco ma protuberans (DFSP). OBJECTIVE: To describe the clinical and histopathological characteristics, treatment and evolution of this rare neoplasm. CLINICAL CASE: A 9-year old female presented with a 2-year history of an indurated, asymptomatic papule on the back of her fourth left toe. The incisio nal biopsy was compatible with pigmented DFSP. The immunohistochemical study showed intense positivity for CD34 throughout the lesion, with negative factor XIIIa. We complemented the study with molecular cytogenetics (FISH) for PDGFB gene (22q13.1) which showed an abnormal pattern in tumor cells, but not in the melanocytes or the peritumoral skin. Delayed Mohs surgery and skin substitute dressing were performed without neoplastic recurrence at 5 years of follow up. Conclu sion: Pigmented DFSP is a low-grade sarcoma that is very rare in pediatric patients. The classical and pigmented variants should be suspected in the presence of a single papulonodular lesion of slow and progressive growth, with presence of spindle cells with storiform pattern in the biopsy and positive immunohistochemical study for CD34. It is an entity with good prognosis, with little risk of recurren ce and metastasis, if complete excision is achieved.

Testing behavioral interventions to optimize participation in a population-based colorectal cancer screening program in Catalonia, Spain.

The aim of the study was to measure the effect of three cost-neutral behavioral interventions on participation compared to the standard invitation letter in a population-based colorectal cancer screening program in 2014. For that purpose, a four-arm randomized field trial was conducted among 5077 individuals aged 50 to 69 years. Over an 8-week period, each week was randomly allocated to the intervention or the control conditions. Individuals assigned to the intervention conditions additionally received a prompt to write down the date to pick up the screening test in a pharmacy. Two of the three intervention groups also included an additional paragraph in the invitation letter on either: 1) the high proportion of individuals participating regularly (social norms condition) or 2) the importance of regular participation (benefit condition). We measured screening participation before and after receiving a reminder letter six weeks after the screening invitation. An overall 8.0 percentage point increase in CRC screening was achieved as a direct result of receiving a reminder letter; however none of the intervention strategies influenced participation. The only significant difference was found for newly invited individuals. There, participation rates decreased from 34.9% to 24.2% when the invitation mailing mentioned the importance of regular participation (OR: 0.60; 95% CI: 0.38-0.95). While none of the intervention strategies improved participation rates we found that praising the benefit of regular screening may discourage individuals who have never been invited before as the continuous behavior may be perceived as a large request. Nevertheless, the reminder letter boosted participation rates independently of the intervention assigned.

[Long-term results of hypospadias surgery. Urinary and sexual function, and psychological impact]. / Resultados a largo plazo de la cirugía de hipospadias. Función urinaria, sexual e impacto psicológico.

OBJECTIVES: To determine the current status of the patients operated on for hypospadias in our region, in order to adapt the surgical technique to their real needs. MATERIAL AND METHODS: A descriptive and observational study. Interviews were conducted with hypospadias surgery patients in our hospital between 1976 and 1996, focusing on their urinary and sexual function and psychological impact. We performed a descriptive statistical analysis and comparisons between types of hypospadias (SPSSv19). RESULTS: 566 patients were operated on for hypospadias during the study period, interviewing 100 aged between 18 and 40 years. The 73% were distal and 27% proximal. Of all patients, 30% do not have an orthotopic meatus, 10% have fistula, 18% have some degree of stenosis and 52% have penile curvature. The 13% feel to have had disadvantages in their life. They consider they have a different penis in: size (19%), glans shape (17%), curvature (14%), scars (10%) and lowest hole (7%). Sexual satisfaction was valued at 8.9 on a scale of 1 to 10, with no differences between the types of hypospadias. Proximal hypospadias patients have more ejaculation problems: 42% versus 11% in distal hypospadias. The 68% of the proximal ones would like to improve compared to 20% of the distal in: appearance (17%), size (11%) and way to urinate (11%). CONCLUSIONS: Anatomic abnormalities are maintained but the aspects that values the adult patient differ from those persecuted by practiced surgeries. A significant percentage of patients would try to get another surgery. Keeping the size of the penis and natural appearance of the glans should be a priority in hypospadias surgery.

OBJETIVOS: Conocer el estado actual de los pacientes intervenidos por hipospadias en nuestra región, para adaptar la técnica quirúrgica a sus necesidades reales. MATERIAL Y METODOS: Estudio descriptivo y observacional. Se entrevistó a pacientes intervenidos de hipospadias en nuestro hospital entre 1976 y 1996, incidiendo en su función urinaria, sexual e impacto psicológico. Realizamos análisis estadístico descriptivo y comparaciones entre tipos de hipospadias (SPSSv19). RESULTADOS: 566 pacientes fueron intervenidos de hipospadias en el período estudiado, entrevistándose a 100, con edades entre 18 y 40 años. El 73% fueron distales y 27% proximales. En el 30% el meato no es ortotópico, 10% presenta fístula, 18% presenta algún grado de estenosis y 52% presenta curvatura. El 13% siente haber tenido desventajas en su vida. Consideran su pene diferente en: tamaño (19%), forma glande (17%), curvatura (14%), cicatrices (10%) y orificio más bajo (7%). La satisfacción sexual fue valorada en 8,9 en una escala del 1 al 10, sin diferencias entre los tipos de hipospadias. Los proximales presentan mayores problemas de eyaculación: 42% frente al 11% de los distales. El 68% de los proximales desearían mejorar frente al 20% de los distales, en apariencia (17%), tamaño (11%) y forma de orinar (11%). CONCLUSIONES: Se mantienen alteraciones anatómicas pero los aspectos que más valora el paciente adulto difieren de los perseguidos en las cirugías que se practicaban. Un porcentaje importante de pacientes se reoperaría de nuevo. Mantener el tamaño del pene y aspecto natural del glande debe ser un objetivo prioritario durante la cirugía de hipospadias.

Cross-sectional survey on awareness of colorectal cancer and a screening programme for primary health care professionals in Catalonia, Spain.

This study aimed to assess whether primary health care professionals have accurate information regarding colorectal cancer (CRC) screening procedures, surveillance recommendations and referral strategies. This cross-sectional descriptive study was based on a survey conducted among primary health care professionals in Barcelona, Spain. The questionnaire was used to gather information regarding CRC screening procedures as well as demographic and professional characteristics of the study subjects. A CRC and screening awareness score (ranging from 0 to 12) was created based on the survey questions. The response rate was 58.9% (206/305). The estimated mean score (standard deviation) was 8.43 (SD: 1.30). For four questions, more than 60% of the answers were incorrect: one related to risk factors, two concerning follow-up colonoscopy, and one related to surveillance. Only 30.8% of the participants believed that they were responsible for determining the appropriate surveillance intervals and for scheduling colonoscopies. Although the professionals had sufficient knowledge of CRC screening, professional knowledge of some aspects related to the major non-modifiable risk factors for the disease and surveillance colonoscopy procedures could be improved. Frequent communication with professionals is necessary to maintain updated screening-related information. Possible methods for facilitating communication could include continuous briefings, regular message reminders or educational websites.

Use of text-message reminders to improve participation in a population-based breast cancer screening program.

To analyze the effect of a cell text message reminder service on participation in a mammogram screening program in Catalonia, Spain. A quasi-experimental design was used with women aged 50 to 69 years who had been scheduled mammogram appointments in June or July 2011. Women were personally invited by letter to attend to the breast cancer screening program (n = 12,786). Prior to the invitation, 3,719 (29.1 %) of them had provided their cell telephone number to the National Health Service. These women received a text message reminder 3 days before their scheduled appointment. Logistic regression models were used to analyze whether the text message reminder was associated with participation in screening. Cost-effectiveness of adding a text message reminder to the invitation letter was also analyzed. The overall rate of participation in breast cancer screening was 68.4 %. The participation rate was significantly higher in the text messaging group, with an age-adjusted OR of 1.56 (95 %CI: 1.43-1.70). A detailed analysis showed that the increase in participation related to the text message reminder was higher among women without previous screening who lived in areas where access to postal mail was limited (OR=2.85; 95 %CI: 2.31-3.53) compared to those who lived in areas of easier postal mail access (OR=1.66; 95 %CI: 1.36-2.02). The invitation letter+text message reminder was a cost-effective strategy. Text message reminders are an efficient cost-effective approach to improve participation in difficult-to-reach populations, such as rural areas and newly developed suburbs.

Comparison of two HIV testing strategies in primary care centres: indicator-condition-guided testing vs. testing of those with non-indicator conditions.

OBJECTIVES: The aim of the study was to compare prospectively indicator-condition (IC)-guided testing versus testing of those with non-indicator conditions (NICs) in four primary care centres (PCCs) in Barcelona, Spain. METHODS: From October 2009 to February 2011, patients aged from 18 to 65 years old who attended a PCC for a new herpes zoster infection, seborrhoeic eczema, mononucleosis syndrome or leucopenia/thrombopenia were included in the IC group, and one in every 10 randomly selected patients consulting for other reasons were included in the NIC group. A proportion of patients in each group were offered an HIV test; those who agreed to be tested were given a rapid finger-stick HIV test (€6 per test). Epidemiological and clinical data were collected and analysed. RESULTS: During the study period, 775 patients attended with one of the four selected ICs, while 66,043 patients presented with an NIC. HIV screening was offered to 89 patients with ICs (offer rate 11.5%), of whom 85 agreed to and completed testing (94.4 and 100% acceptance and completion rates, respectively). In the NIC group, an HIV test was offered to 344 persons (offer rate 5.2%), of whom 313 accepted (90.9%) and 304 completed (97.1%) testing. HIV tests were positive in four persons [prevalence 4.7%; 95% confidence interval (CI) 1.3-11.6%] in the IC group and in one person in the NIC group (prevalence 0.3%; 95% CI 0.01-1.82%; P < 0.009). If every eligible person had taken an HIV test, we would have spent €4650 in the IC group and €396,258 in the NIC group, and an estimated 36 (95% CI 25-49) and 198 persons (95% CI 171-227), respectively, would have been diagnosed with HIV infection. The estimated cost per new HIV diagnosis would have been €129 (95% CI €107-153) in the IC group and €2001 (95% CI €1913-2088) in the NIC group. CONCLUSIONS: Although the number of patients included in the study was small and the results should be treated with caution, IC-guided HIV testing, based on four selected ICs, in PCCs seems to be a more feasible and less expensive strategy to improve diagnosis of HIV infection in Spain than a nontargeted HIV testing strategy.
