Máculas hiperpigmentadas y prolapso rectal, ¿qué debemos sospechar? / Hyperpigmented macules and rectal prolapse, what should we suspect?

El síndrome de Peutz-Jeghers (SPJ) es un síndrome autosómico dominante con una incidencia de 1 de cada 200 000 nacidos vivos. Las manifestaciones clínicas más frecuentes son las máculas hiperpigmentadas típicamente localizadas en la mucosa oral y la presencia de pólipos en el tracto gastrointestinal. A diferencia de la edad adulta, en Pediatría es excepcional el desarrollo de patología tumoral maligna. Sin embargo, en la edad pediátrica hay que tener un elevado índice de sospecha ante un paciente con diagnóstico de SPJ que presenta dolor abdominal compatible con una invaginación intestinal, ya que esta complicación es relativamente frecuente y precisa tratamiento quirúrgico urgente. Una vez realizado el diagnóstico de esta enfermedad, se deberán llevar a cabo controles periódicos mediante endoscopias a partir de los ocho años de edad (AU)

Peutz-Jeghers syndrome (PJS) is an autosomal dominant syndrome with an incidence of 1 in 200,000 live births. The most frequent clinical manifestations are hyperpigmented macules typically located on the oral mucosa and the presence of polyposis in the gastrointestinal tract.Unlike adulthood, in pediatrics the development of malignant tumor pathology is exceptional. However, in the pediatric age group, a high index of suspicion must be maintained when faced with a patient diagnosed with PJS who presents with abdominal pain compatible with intussusception, since this complication is relatively frequent and requires urgent surgical treatment. Once the diagnosis of this disease has been made, periodic controls should be carried out by means of endoscopies starting at eight years of age. (AU)

Panadizo herpético en lactante de 20 meses / Herpetic whitlow in a 20-month-old infant

El panadizo herpético es una lesión cutánea producida por el virus herpes simple, en pediatría especialmente el virus herpes tipo 1. Es una lesión que se debe conocer para evitar realizar un diagnóstico incorrecto e instaurar tratamientos innecesarios o incluso perjudiciales. La presentación clínica habitual es una lesión con vesículas arracimadas, cuya localización típica es en primer o segundo dedo. En los pacientes pediátricos es frecuente que se produzca tras autoinoculación desde una gingivoestomatitis herpética, por lo que ante la sospecha de esta lesión es importante la exploración física completa incluyendo orofaringe. El curso es autorresolutivo aunque en ocasiones puede ser necesario instaurar tratamiento con aciclovir oral. El drenaje de la lesión está contraindicado porque puede llegar a producir una diseminación del virus herpes con graves consecuencia (AU)

Herpetic whitlow is a skin lesion caused by the herpes simplex virus (HSV), usually type 1 in the paediatric population. Providers must be aware of this lesion to avoid making an incorrect diagnosis and initiating unnecessary or even harmful treatments.The usual presentation is a lesion with clustered vesicles, typically located on the first or second toe. In paediatric patients, it is often the result of autoinoculation from HSV gingivostomatitis lesions, so when this lesion is suspected, it is important to carry out a complete physical examination including the oropharynx.The course is self-limiting, although on occasion treatment with oral acyclovir becomes necessary. Drainage of the lesion is contraindicated because it could lead to dissemination of HSV with severe consequences. (AU)

Solution and Solid-State Photophysical Properties of Positional Isomeric Acrylonitrile Derivatives with Core Pyridine and Phenyl Moieties: Experimental and DFT Studies.

The compounds I (Z)-2-(phenyl)-3-(2,4,5-trimethoxyphenyl)acrylonitrile with one side (2,4,5-MeO-), one symmetrical (2Z,2'Z)-2,2'-(1,4-phenylene)bis(3-(2,4,5-trimethoxyphenyl)acrylonitrile), II (both sides with (2,4,5-MeO-), and three positional isomers with pyridine (Z)-2-(pyridin-2- 3, or 4-yl)-3-(2,4,5-trimethoxyphenyl)acrylonitrile, III-V were synthetized and characterized by UV-Vis, fluorescence, IR, H1-NMR, and EI mass spectrometry as well as single crystal X-ray diffraction (SCXRD). The optical properties were strongly influenced by the solvent (hyperchromic and hypochromic shift), which were compared with the solid state. According to the solvatochromism theory, the excited-state (µe) and ground-state (µg) dipole moments were calculated based on the variation of Stokes shift with the solvent's relative permittivity, refractive index, and polarity parameters. SCXRD analyses revealed that the compounds I and II crystallized in the monoclinic system with the space group, P21/n and P21/c, respectively, and with Z = 4 and 2. III, IV, and V crystallized in space groups: orthorhombic, Pbca; triclinic, P-1; and monoclinic, P21 with Z = 1, 2, and 2, respectively. The intermolecular interactions for compounds I-V were investigated using the CCDC Mercury software and their energies were quantified using PIXEL. The density of states (DOS), molecular electrostatic potential surfaces (MEPS), and natural bond orbitals (NBO) of the compounds were determined to evaluate the photophysical properties.

Moderate-to-Vigorous Physical Activity and Body Composition in Children from the Spanish Region of Aragon.

Most of the studies analyzing the effect of moderate to vigorous physical activity (MVPA) on children's health do not contain information on early stages or do not use accurate methods. We investigated the association between PA and body composition using objective methods, perinatal data, lifestyle behaviors, and World Health Organization (WHO) physical activity (PA) recommendations. The CALINA study is a longitudinal observational cohort study of children born in Aragon (Spain) in 2009. A total of 308 7-year-old children (52.3% boys) were assessed. We used dual-energy X-ray absorptiometry (DXA) and accelerometry. Rapid weight gain until 12 months and lifestyle behaviors were considered as covariates both in the ANCOVA and linear regression models. A higher percentage of boys met the WHO PA recommendations compared to girls (69.6% vs. 40.9%, respectively; p < 0.001). There was a negative association between MVPA and subtotal fat and abdominal fat in both girls and boys. After adjusting for perinatal and lifestyle variables, we found that subtotal body fat, abdominal fat, and fat mass index (FMI) were significantly lower in those classified as active. MVPA was associated with body fat both in boys and girls. More research is needed to identify the cutoffs points of MVPA that generate benefit to boys and girls in all body composition components.

Implementation of a novel home delivery service during pandemic.

INTRODUCTION: During the COVID-19 pandemic, measures have been put in place to adapt to patients' needs during home quarantine, such as "telehealthcare". With this service, hospital pharmacists develop a distinct role via the implementation of pharmacovigilance services and pharmaceutical care plans for patients with comorbidities, and for special populations as immunosuppressed patients.MethodsCross-sectional study involving hospital and community pharmacists actively practising during the COVID-19 pandemic. Patients who could not come to the hospital pharmacy department were provided with a delivery service to the community pharmacy of their choice. RESULTS: A total of 1186 patients requested this service. Erythropoiesis-stimulating agents were the most in-demand medication, followed by rheumatoid arthritis and antiretroviral drugs. 125 patients responded to the telephone survey, most of whom stated that they would use the delivery service again, and expressed their desire to continue doing so. DISCUSSION: Without a doubt, telepharmacy and medication delivery services have provided multiple benefits during home quarantine. The delivery service enabled us to provide drugs to patients in their immediate environment through a service that was free for both the patient and the hospital pharmacy service. However, at present, the available evidence of the impact of telepharmacy models is sparse. CONCLUSIONS: This medication delivery service has provided multiple benefits to patients during home quarantine. Although the users of this service seem to be satisfied with the current model, in the future, we should consider which patients would benefit most from this service and shape it to individual needs.

Guselkumab in moderate-to-severe plaque psoriasis: effectiveness in real clinical practice / Guselkumab en placa de moderada a grave psoriasis: eficacia en la práctica clínica real

Introducción: La psoriasis es una enfermedad cutánea inflamatoria crónica inmunomediada que afecta a casi el 1-2% de la población mundial. El tratamiento biológico de la psoriasis moderada a grave ha cambiado el paradigma de manejo de la enfermedad, permitiendo un mejor control de la misma. Métodos: Se llevo a cabo un estudio observacional retrospectivo que incluyó a pacientes con psoriasis moderada a grave que fueron tratados durante al menos 36 semanas con guselkumab. La eficacia se evaluó mediante la estimación de pacientes que alcanzaron las respuestas PASI 75, PASI 90 y PASI 100 en las semanas 16, 24 y 36. Se utilizó la prueba T de Student para muestras pareadas para determinar la significación estadística entre PASI al inicio y respuesta PASI en las semanas 16, 24 y 36. Resultados: Se incluyeron 22 pacientes, 14 mujeres (63, 6%), con una edad media de 48, 7 ± 15, 5 años. El tratamiento con guselkumab redujo el PASI medio de 10, 3 ± 6 al inicio del estudio a 2, 4 ± 2 (p = 0,003), 1, 3 ± 1, 8 (p = 0,001) y 0, 3 ± 0, 6 (p = 0,001) a las 16, 24 y 36 semanas, respectivamente. Discusión: El primer fármaco en unirse al arsenal terapéutico anti-IL23 fue guselkumab. La eficacia obtenida fue superior a la observada en estudios fase III para PASI 90 y 100 a la semana 36. Existen algunos estudios que han evaluado la eficacia a corto plazo de guselkumab en la práctica clínica real; sin embargo, este fármaco se ha comercializado recientemente, limitando la posibilidad de evaluación durante períodos de tiempo más prolongados. Conclusión: Guselkumab presenta buenos resultados en el manejo de la psoriasis en adultos. La práctica clínica real a medio y largo plazo será fundamental, con un mayor tamaño muestral y período de seguimiento.

Introduction: Psoriasis is a chronic immune­ mediated inflammatory skin disease that affects nearly 1­2% of the population worldwide. Biologic treatment of moderate-to-severe psoriasis has changed the disease management paradigm, allowing for better disease control. Methods: A retrospective observational study including patients with moderate-to-severe psoriasis who were treated for at least 36 weeks with guselkumab. Efficacy was evaluated by estimating the proportion of patients achieving PASI 75, PASI 90 and PASI 100 responses at weeks 16, 24 and 36. The Student t-test for paired samples was used to determine the significant difference in outcome of patients between PASI at baseline and PASI response at weeks 16, 24 and 36. Reslts: 22 patients were included, 14 women (63.6%), with mean age of 48.7±15.5. Guselkumab treatment decreased mean PASI from 10.3±6 at baseline to 2.4±2 (p=0.003), 1.3±1.8 (p=0.001) and 0.3±0.6 (p=0.001) at 16, 24 and 36 weeks, respectively. Discussion: The first anti-IL23 drug family to join the therapeutic arsenal is guselkumab. The efficacy obtained is higher than that observed in phase III studies for PASI 90 and 100 at week 36. There are some studies that have evaluated the short-term effectiveness of guselkumab in real clinical practice; however, this drug has only recently been marketed, limiting the possibility of as yet longer treatment periods. Conclusion: Guselkumab shows great results in the management of psoriasis in adults. Medium- and long-term real clinical practice will be essential, with a larger sample size and longer follow-up period.

A low molecular weight OLED material: 2-(4-((2-hydroxyethyl)(methyl)amino)benzylidene)malononitrile. Synthesis, crystal structure, thin film morphology, spectroscopic characterization and DFT calculations.

2-(4-((2-Hydroxyethyl)(methyl)amino)benzylidene)malononitrile (HEMABM) was synthesized from 4-[hydroxymethyl(methyl)amino]benzaldehyde and propanedinitrile to obtain a low molecular weight fluorescent material with an efficient solid-state emission and electroluminescence properties comparable to the well-known poly(2-methoxy-5(2'-ethyl)hexoxyphenylenevinylene) (MEH-PPV). The HEMABM was used to prepare an organic light-emitting diode by a solution process. Despite the title compound being a small molecule, it showed optical properties and notable capacity to form a film with smooth morphology (10.81 nm) closer to that of polymer MEH-PPV (10.63 nm). The preparation of the device was by spin coating, the electrical properties such as threshold voltage were about 1.0 V for both HEMABM and MEH-PPV, and the luminance 1300 cd m-2 for HEMABM and 2600 cd m-2 for MEH-PPV. This low molecular weight compound was characterized by SCXRD, IR, NMR, and EI. Besides a quantitative analysis of the intermolecular interactions by PIXEL, density functional theory (DFT) calculations are reported.

Resultados de morbimortalidad en cáncer colorrectal en paciente quirúrgico frágil. Implementación de un Área de Atención al Paciente Quirúrgico Complejo / Colorectal carcinoma in the frail surgical patient. Implementation of a Work Area focused on the Complex Surgical Patient improves postoperative outcome

INTRODUCCIÓN: La edad avanzada y la presencia de comorbilidades repercuten en la morbimortalidad postoperatoria del paciente quirúrgico frágil. El objetivo de este estudio es valorar los resultados de morbimortalidad tras cirugía por cáncer colorrectal en el paciente quirúrgico frágil tras la implementación de un Área de Atención al paciente Quirúrgico Complejo (AAPQC). MÉTODOS: Estudio retrospectivo con recogida prospectiva de datos. Un total de 91 pacientes consecutivos considerados como frágiles (ASAIV o ASAIII con Barthel < 80 i/o Pfeiffer>3) fueron intervenidos entre 2013 y 2015 con diagnóstico de cáncer colorrectal con intención curativa. Grupo I (AAPQC): 35 pacientes incluidos en AAPQC durante 2015. Grupo II (No AAPQC): 56 pacientes intervenidos entre 2013 y 2014 previa implementación del AAPQC. Se analizó homogeneidad de grupos, complicaciones, estancia media, mortalidad, reintervenciones, reingresos y costes en función del GRD. RESULTADOS: No se encontraron diferencias significativas en edad, sexo, ASA, índex de masa corporal, estadio tumoral y tipo de intervención quirúrgica entre los dos grupos. Las complicaciones mayores (Clavien-DindoIII-IV) (11,4% vs. 28,5%, p = 0,041), la estancia media (12,6 ± 6 días vs. 15,2 ± 6 días, p = 0,043), los reingresos (11,4% vs. 28,3%, p = 0,041) y el peso específico del episodio (3,29 ± 1 vs 4,3 ± 1, p = 0,008) fueron significativamente menores en el grupo AAPQC. No hubo diferencias en re intervenciones (6,2% vs. 5,3%) ni mortalidad (6,2% vs 7,1%). El 96,9% de pacientes del grupo I manifestó una atención y calidad de vida satisfactoria. CONCLUSIONES: La implementación de una AAPQC en pacientes frágiles que deben ser intervenidos de cáncer colorrectal comporta una reducción de las complicaciones, estancia y reingresos, y es una medida coste-efectiva

INTRODUCTION: Advanced age and comorbidity impact on post-operative morbi-mortality in the frail surgical patient. The aim of this study is to assess the impact of a comprehensive, multidisciplinary and individualized care delivered to the frail patient by implementation of a Work Area focused on the Complex Surgical Patient (CSPA). METHODS: Retrospective study with prospective data collection. Ninety one consecutive patients, classified as frail (ASAIII or IV, Barthel<80 and/or Pfeiffer>3) underwent curative radical surgery for colorectal carcinoma between 2013 and 2015. GroupI: 35 patients optimized by the CSPA during 2015. Group II: 56 No-CSPA patients, treated prior to CSPA implementation, during 2014-2015. Group homogeneity, complication rate, length of stay, reoperations, readmissions, costs and overall mortality were analyzed and adjusted by Diagnosis-Related Group (DRG). RESULTS: There were no statistically significant differences in term of age, gender, ASA classification, body mass index, tumor staging and type of surgical intervention between the two groups. Major complications (Clavien-DindoIII-IV) (12.5% vs. 28.5%, P = .04), hospital stay (12.6 ± 6 days vs. 15.2 ± 6 days, P = 0.041), readmissions (12.5% vs. 28.3%, P < 0.041), and patient episode cost weighted according to DRG (3.29 ± 1 vs. 4.3 ± 1, P = 0.008) were statistically inferior in Group CSPA. There were no differrences in reoperations (6.2% vs. 5.3%) or mortality (6.2% vs. 7.1%). 96.9% of patients of Group I manifested having received a satisfactory attention and quality of life. CONCLUSIONS: Implementation of a CSPA, delivering surgical care to frail colorectal cancer patients, involves a reduction of complications, length of stay and readmissions, and is a cost-effective arrangement

Úlceras genitales de Lipschütz: reporte de un caso pediátrico / Lipschütz ulcers: a pediatric case report

Las úlceras genitales son una patología poco frecuente en las consultas de pediatría, pero que generan gran ansiedad familiar. Las úlceras de Lipschütz son úlceras vulvares agudas, dolorosas y autolimitadas de causa desconocida. Aparecen en mujeres jóvenes que no han tenido relaciones sexuales previas o tras un período de abstinencia. Paciente de 10 años con úlceras vulvares dolorosas que, tres días antes de la aparición de las lesiones, había presentado un cuadro de deposiciones diarreicas y fiebre. Se realizó una anamnesis y exploración física detallada y se llevaron a cabo diferentes pruebas complementarias para descartar enfermedades infecciosas de origen venéreo y no venéreo, todas ellas negativas. Se indicó tratamiento sintomático, y se observó, al mes, una completa resolución del cuadro, por lo que se confirmó el diagnóstico de úlceras de Lipschütz.

Genital ulcers are a rare entity in pediatric consultation, but they generate great family anxiety. Lipschütz ulcers are acute, painful, and self-limiting vulvar ulcers of unknown cause. These ulcers appear in young women who have not had previous sexual intercourse or after a period of sexual abstinence. We present a 10-year-old girl with painful vulvar ulcers with a 3-day history of diarrhea and fever before the onset of the lesions. A complete anamnesis and detailed physical examination were carried out and complementary tests were performed to investigate sexually and non-sexually transmitted disease; the results were negative. Symptomatic treatment was started; at one-month follow-up a complete resolution of ulcers confirmed the diagnosis of ulcer of Lipschütz.

Adherence to highly active antiretroviral therapy (HAART): a meta-analysis.

This meta-analysis synthesizes eighty-four observational studies, conducted across twenty countries, to determine the mean proportion of people who reported ≥90% adherence to prescribed highly active antiretroviral therapy (HAART) and to identify the factors associated with high levels of adherence. Eight electronic databases were searched to locate all relevant studies available by January 2010, which were then coded for sample characteristics and adherence levels. The average rate of reporting ≥90% adherent HAART adherence is 62%. However, this proportion varies greatly across studies. In particular, a greater proportion of individuals maintaining ≥90% adherence to HAART is more likely in studies with higher proportions of men who have sex with men (MSM) and lower proportions of injection drug users (IDU), with participants in an earlier stage of infection, and in studies conducted in countries characterized by lower Human Development Index (HDI) scores.

Cisplatino y 5-Fluorouracilo en perfusión continua de 96 horas para canceres recidivantes o metastasicos de cabeza y cuello / Cisplatine and 5-Fluorouracil in continuing perfusion during 96 hours to recurrents or metastasis in head and neck

A 36 pacientes con carcinoma epidermoide recurrente o metastásico de cabeza y cuello fueron tratados con cisplatino y 5-fluorouracilo, ambos en perfusión continua de 96 horas. Veintiocho presentaban recidiva local, seis metástasis y dos recidiva local y a distancia. Trece habían recibido previamente quimioterapia. Se consiguieron ocho respuestas completas (22 por ciento) y siete parciales (19 por ciento), con una respuesta objetiva del 41 por ciento. La supervivencia actuarial durante un periodo de seguimiento de 59 meses fue del 17 por ciento, con una supervivencia media de ocho meses. La supervivencia actuarial en los pacientes con respuesta completa fue del 50 por ciento a los 59 meses. Las manifestaciones de toxicidad más frecuentemente encontradas fueron estomatitis, leucopenia y vómitos. El esquema terapéutico resulta efectivo y beneficia principalmente a los pacientes con recidiva local, en los cuales es posible conseguir respuesta completa.
