Effectiveness of high-intensity laser therapy in the treatment of patients with frozen shoulder: a systematic review and meta-analysis.

The purpose of this study is to evaluate the effects of high-intensity laser therapy (HILT) in patients with frozen shoulder. PRISMA guidelines were adhered to, and a systematic search was conducted in the PubMed, Web of Science, Scopus, CINAHL, Science Direct, and PEDro databases (last update: September 4, 2023; search period: December 2022-September 2023). The inclusion criteria encompassed RCTs comparing HILT with other physical therapy interventions in frozen patients with frozen shoulders, with or without sham HILT, assessing pain intensity, shoulder ROM, and disability outcomes. The quality of the RCTs was assessed with the Cochrane Risk of Bias tool, and evidence was assessed using the GRADE approach. Five trials met the eligibility criteria and were included in the review and meta-analysis, which pooled results from the visual analog scale (VAS), goniometry, and the shoulder pain and disability index (SPADI). Mean differences (MDs) for pain intensity and disability show a pooled effect in favor of HILT both for VAS (MD = - 2.23 cm, 95% CI: - 3.25, - 1.22) and SPADI (MD = - 10.1% (95% CI = - 16.5, - 3.7), changes that are statistical (p < 0.01) and clinical. The MD for flexion (MD = 9.0°; 95% CI: - 2.36°, 20.3°; p = 0.12), abduction (MD = 3.4°; 95% CI: - 6.9°, 13.7°; p = 0.51), and external rotation (MD = - 0.95°; 95% CI: - 5.36°, 3.5°; p = 0.67) does not show statistical and clinical differences between groups after treatment. PI and disability changes were graded as important due to their clinical and statistical results. HILT into a physical therapy plan reduce pain and disability, but it does not outperform conventional physical therapy in improving shoulder ROM. It is suggested that future RCTs compare the effects of HILT and LLLT to assess their possible differences in their analgesic effects.

Reconocimiento de agentes reproductores de saberes y prácticas populares en salud. Municipio de Andes 2019 / Recognition of reproductive agents of popular knowledge and practices in health. Municipality of Andes, 2019 / Reconhecimento de agentes reprodutores de saberes e práticas populares em saúde. Município de Andes 2019

Resumen Objetivos: El estudio pretende reconocer la existencia de agentes portadores y reproductores de prácticas y saberes populares en salud, sus dominios y dinámica en el espacio social. Georreferenciar sus dinámicas y establecer su relación con el Plan Básico de Ordenamiento Territorial. Metodología: Estudio cualitativo analítico, que conjuga la geografía crítica y la etnografía. Mediante el uso de técnicas de georreferenciación, -localización y espacialización-, con uso del software QGIS versión 3.6 Nossa. Y mediante el uso de técnicas de entrevistas a profundidad y observaciones documentadas, información que se ordenó y sistematizó por categorías, mediante la implementación del programa ATLAS.ti versión 9. Resultados: Se reconocieron más de 60 agentes y se localizaron 48. Se reconocen dos dominios del saber popular: el mágico religioso, expresado en sobanderos con secreto, y el curanderismo expresado en hierbateros, rezanderos y sobanderos. Se legitiman a través de su presencia en espacios sociales, en sus tres dimensiones: material, al portar una identidad y un dominio, que habitan con objetos; mental, el cual cargan de relaciones y simbolismos; y político, donde reproducen una cadena comercial vinculada a la zona de vocación comercial establecida por el PBOT del municipio. Conclusiones: Los agentes, sus prácticas y saberes se determinan y legitiman, a partir de actos de reproducción social, cultural y política en el territorio como espacio social, y en sus dimensiones, a partir de expresiones culturales, simbolismos y rituales, relaciones materiales a partir del intercambio con objetos y servicios, y su asiento político en las zonas de vocación territorial.

Abstract Objectives: The study aims at recognizing the existence of agents carrying and reproducing popular practices and knowledge in health, their domains and dynamics in the social space and at geo-positioning their dynamics and establishing their relationship with the Basic Plan of Territorial Planning. Methodology: qualitative analytical study that combines critical geography through georeferencing techniques, -localization and spatialization-, using the QGIS Version 3.6 Nossa program, and ethnography through the use of in-depth interview techniques and observations, information that was organized and systematized by categories through the implementation of the ATLAS.ti version 9 program. Results: More than 60 agents were recognized and 48 were located. Two domains of popular knowledge were recognized: the Religious Magic, expressed in massage therapists (sobanderos) with secrecy, and folk medicine (Curanderismo) expressed in shamans, rezanderos and sobanderos. They are legitimized through their presence in social spaces in their 3 dimensions: material by carrying an identity and a domain inhabiting objects; mental which is loaded with relationships and symbolism; and political where they reproduce an overlapping and expanded commercial chain, linked to the area of commercial vocation delimited by the PBOT of the municipality. Conclusions: Agents, their practices and knowledge are determined and legitimized based on acts of social, cultural and political reproduction in the territory as a social space, and in their dimensions based on cultural expressions, symbolisms and rituals, material relationships from the exchange with objects and services and settled politically in the areas of territorial vocation.

Legitimam-se através de sua presença em espaços sociais, em suas três dimensões: material, ao trazer uma identidade e um domínio, que habitam com objetos; mental, o qual carregam de relaciones e simbolismos; e político, onde reproduzem uma cadeia comercial vinculada à zona de vocação comercial estabelecida pelo PBOT do município. Conclusões: os agentes, suas práticas e saberes se determinam e legitimam, a partir de atos de reprodução social, cultural e política no território como espaço social, e em suas dimensões, a partir de expressões culturais, simbolismos e rituais, relações materiais a partir do intercâmbio com objetos e serviços, e sua posição política nas zonas de vocação territorial.

Reconocimiento de Saberes Tradicionales en Salud. Andes, Antioquia 2019: Aproximación Cualitativa / Recognition of Traditional Health Knowledge. Andes, Antioquia 2019: Qualitative Approach

Introducción: revalorizar y resignificar la identidad de los saberes tradicionales en salud es retador, en una cultura mediada por la industrialización, perviviendo con un pasado histórico, patrimonial cultural y simbólico, desde una identidad mixturada que se conjuga en un sincretismo territorial, que persiste a través de huellas físicas y culturales de tradiciones mágico religiosas. Objetivo: reconocer las particularidades etnográficas de los agentes portadores de saberes populares en salud que les permite afianzar sus prácticas en el municipio de Andes- Antioquia. Y resignificar estas prácticas para recuperar sus entornos identitarios y rituales simbólicos, en la configuración de su identidad como cuerpo orgánico en los espacios sociales. Metodología: investigación cualitativa, de tipo descriptivo, con perspectiva etnográfica (microetnográfica), sistematizada a través de entrevistas a profundidad acompañadas de registros fotográficos y observaciones participantes. Resultados: se reconocen 48 agentes sociales entre 30 y 70 años, la mayoría asentados en la ruralidad. Entre ellos: sobanderos con secreto, sobanderos con dolor o componedores, hierbateros y rezanderos. Se reconoce su identidad diversa desde una emergencia mágica religiosa y se exponen las características de sus saberes heredados, en una ritualidad envolvente que los recrea y vitaliza en los espacios sociales. Discusión: se analizan los resultados en el marco del espacio social, multidimensional y complejo, a través de sus tres elementos: estructuras sociales, relaciones sociales y formas espaciales. Conclusiones: las formas espaciales trasladan el simbolismo al espacio social físico con características que afianzan el ejercicio de su saber y su identidad. La brecha entre los conocimientos occidentales y los saberes tradicionales se cierra cada vez más por la fuerza de sus realidades en la vida cotidiana, de una sociedad globalizada.

Introduction: revaluing and re-signifying the identity of traditional health knowledge is challenging in a culture mediated by industrialization, surviving with a historical past, cultural and symbolic heritage, from a mixed identity that is conjugated in a territorial syncretism, which persists through physical and cultural traces of magical-religious traditions. Objective: to recognize the ethnographic particularities of the agents who carry popular knowledge in health that allows them to strengthen their practices in the Andes-Antioquia municipality. To re-signify these practices to recover their identity and symbolic ritual environments, in the configuration of their identity as an organic body in social spaces. Methodology: qualitative, descriptive type research, with ethnographic perspective (micro-ethnographic), systematized through in-depth interviews, accompanied by photographic records and participant observations. Results: 48 social agents between 30 and 70 years old, most of them settled in rural areas, were identified. Among them: sobanderos with secret, sobanderos with pain or componedores, hierbateros and rezanderos. Their diverse identity is recognized from a magical religious emergence and the characteristics of their inherited knowledge are exposed, in an enveloping rituality that recreates and vitalizes them in social spaces. Discussion: the results are analyzed within the framework of social, multidimensional and complex spaces, through its three elements: social structures, social relations and spatial forms. Conclusions: spatial forms transfer symbolism to the physical social space with characteristics that strengthen the exercise of their knowledge and identity. The gap between western knowledge and traditional knowledge is closing more and more due to the strength of its realities in the daily life of a globalized society.

Introdução: revalorizar e resignificar a identidade dos conhecimentos tradicionais em saúde é um desafio em uma cultura mediada pela industrialização, sobrevivendo com um passado histórico, cultural e simbólico, a partir de uma identidade mista de sincretismo territorial, que persiste através de traços físicos e culturais de tradições mágico-religiosas. Objetivo: reconhecer as particularidades etnográficas dos agentes portadores de conhecimentos populares em saúde que lhes permitam fortalecer suas práticas no município de Andes, Antioquia. E resignificar estas práticas a fim de recuperar seus espaços de identidade e rituais simbólicos, na configuração de sua identidade como um corpo orgânico em espaços sociais. Metodologia: pesquisa qualitativa, descritiva, com uma perspectiva etnográfica (microetnográfica), sistematizada através de entrevistas em profundidade acompanhadas de registros fotográficos e observações dos participantes.

Conclusões: As formas espaciais traduzem o simbolismo em espaço social físico com características que fortalecem o exercício de seu conhecimento e identidade. A distância entre o conhecimento ocidental e o conhecimento tradicional está se fechando cada vez mais devido à força de suas realidades na vida cotidiana em uma sociedade globalizada.

Linfoma primario cutáneo de células T epidermotropo agresivo CD8+ / Primary cutaneous aggressive epidermotropic CD8 + T-cell lymphoma

El linfoma de células T epidermotropo agresivo CD8+ o linfoma de Berti es un subtipo infrecuente de los linfomas primarios cutáneos, descripto en 1999. Aún se considera una entidad provisional en la última clasificación de linfomas cutáneos primarios de la Organización Mundial de la Salud. Predomina en los hombres adultos y se manifiesta con pápulas, placas hiperqueratósicas y tumores ulcerados, diseminados y de inicio agudo. En la histopatología, es característica la presencia de un infiltrado de linfocitos atípicos medianos CD8 +, con epidermotropismo de patrón pagetoide. Tiene un comportamiento agresivo y es de mal pronóstico, con una sobrevida a los 5 años menor del 40%. Si bien esta entidad es un reto terapéutico, el tratamiento inicial se basa en poliquimioterapia y/o trasplante de células hematopoyéticas.

The aggressive epidermotropic CD8+ T-cell lymphoma or Berti's lymphoma, is a rare subtype of primary cutaneous lymphomas, first described in 1999. It is still considered a provisional entity by the latest World Health Organization classification of cutaneous lymphomas. Patients are commonly adults with a male predominance and it is characterized by widespread rapid evolving papules, hyperkeratotic annular plaques and ulcerated tumors.

Identificación genética del orégano de Putre (Origanum vulgare L) mediante ITS y microsatélites, una especie reconocida en Chile con Sello de Origen / Genetic identification of the Putre's oregano (Origanum vulgare L) by ITS and microsatellites, a species recognized in Chile with Seal of Origin

Putre ́s oregano (Origanum vulgare L.) is a variety of oregano that grown in the Arica-Parinacota Region. Its organoleptic attributes and unique production conditions have earned it a certification with Geographical Indication (GI). However, the demands of the markets require a scientific-technological support for identification and authentication of materials. In this context, was proposed to identify Putre's oregano by phylogenetic relationships based on the use of molecular markers SSR and "DNA Barcode". The results showed that when comparing materials from different sources of Putre ́s oregano versus information from certified germplasms and GenBank sequences, added to the analysis with nuclear genetic markers, Putre ́s oregano corresponds to the species Origanum vulgare L. subsp virens. This precise identification will support the correct differentiation and authentication of this genotype, serving in addition to supporting the GI.

El orégano de Putre (Origanum vulgare L.) es una variedad de orégano que se cultiva en la Región de Arica y Parinacota. Sus atributos organolépticos y condiciones únicas de producción lo han hecho acreedor de una certificación con Indicación Geográfica (IG). Sin embargo, las exigencias de los mercados requieren de un respaldo científico-tecnológico de identificación y autenticación de materiales. En este contexto, se propuso identificar el orégano de Putre mediante relaciones filogenéticas a partir del uso de marcadores moleculares SSR y "DNA Barcode". Los resultados demostraron que al comparar los materiales de distintas procedencias de orégano de Putre versus la información desde germoplasmas certificados y secuencias de GenBank, sumado al análisis con marcadores genéticos nucleares, el orégano de Putre corresponde a la especie Origanum vulgare L. subsp virens. Esta identificación precisa dará soporte a la correcta diferenciación y autenticación de este genotipo, sirviendo además de apoyo a la IG.

Primary cutaneous lymphoma in Argentina: a report of a nationwide study of 416 patients.

BACKGROUND: The aim of this study was to determine the relative frequency of primary cutaneous lymphoma (PCL) in Argentina according to the new World Health Organization (WHO)-European Organization for the Research and Treatment of Cancer (EORTC) classification system. METHODS: A total of 416 patients from 21 dermatology services were included during a 5-year period (2010-2015); these patients were classified using WHO-EORTC criteria. RESULTS: There were 231 (55.2%) males and 185 (44.8%) females; the male-to-female ratio was 1.35. The median age of the patients was 57 years (range, 0-90 years). Most patients were Caucasian (79%), and only 16% of patients were registered as Amerindian. Most patients (387/416, 93%) had cutaneous T-cell lymphoma (CTCL); 28 patients (6.7%) were diagnosed with cutaneous B-cell lymphoma (CBCL). The most frequent CTCL subtypes, in decreasing order of prevalence, were mycosis fungoides (MF), including its variants (75.7%); CD30+ primary cutaneous lymphoproliferative disorders (7.2%); and Sézary syndrome (SS) (3.1%). Cutaneous follicle center lymphoma was the most common CBCL subtype (2.9%). In the subset of patients ≤20 years of age, the most common condition was MF (57%), followed by extranodal NK-T nasal-type lymphoma (14%). CONCLUSIONS: This study revealed relatively higher rates of MF and lower rates of CBCL in Argentinean patients that have been reported in American and European countries.

Genomic imbalances and microRNA transcriptional profiles in patients with mycosis fungoides.

Mycosis fungoides is the most common type of primary cutaneous T cell lymphoma. We have evaluated CDKN2A losses and MYC gains/amplifications by FISH analysis, as well as expression of miR-155 and members of the oncogenic cluster miR-17-92 (miR17, miR18a, miR19b, and miR92a) in MF patients with advanced disease. Formalin-fixed paraffin-embedded skin biopsies from 36 patients at diagnosis, 16 with tumoral MF (T-MF), 13 in histological transformation to a large T cell lymphoma (TR-MF), and 7 cases with folliculotropic variant (F-MF), were studied. Twenty cases showed genomic alterations (GAs): 8 (40 %) had CDKN2A deletion, 7 (35 %) showed MYC gain, and 5 (25 %) exhibited both alterations. GAs were more frequently observed in F-MF (p = 0.004) and TR-MF (p = 0.0001) than T-MF. GAs were significantly higher in cases presenting lesions in head, neck, and lower extremities compared to those observed in trunk and upper extremities (p = 0.03), when ≥25 % neoplastic cells were CD30 positive (p = 0.016) as well as in cases with higher Ki-67 proliferation index (p = 0.003). Patients with GAs showed bad response to treatment (p = 0.02) and short survival (p = 0.04). Furthermore, MF patients showed higher miRNA expression compared to controls (p ≤ 0.0223). T-MF showed higher miR17 and miR-18a expression compared to F-MF and TR-MF (p ≤ 0.0387) while miR19b, miR92a, and miR-155 showed increased levels in F-MF and TR-MF with respect to T-MF (p ≤ 0.0360). Increased expression of miR17 and miR19b in GA group compared to cases without alterations (p ≥ 0.0307) was also detected. Our results add new information about genomic imbalances in MF patients, particularly in F-MF, and extend the present view of miRNA deregulation in this disease.

Unusual variants of mycosis fungoides.

Unusual variants of mycosis fungoides (MF) differ substantially from the classical presentation, and most of them resemble other dermatologic diseases. The authors reviewed files of patients with MF who consulted our clinic between November 1995 and June 2010 to evaluate the relative frequency and clinical behavior of these variants. Among 98 patients with MF, 32 (32.65%) had unusual variants. The most common types included follicular MF (31.25%), hypopigmented MF (18.75%), poiquilodermic MF (15.6%), and erythrodermic MF (12.5%). Less common variants included unilesional MF, bullosa MF, ichthyosiform MF, granulomatous slack skin, and pigmented purpura-like MF. Progressive disease and MF-related death were most commonly associated with follicular MF, bullosa MF, and erythrodermic MF.

Síndrome linfoproliferativos CD30+. Serie de 26 casos y revisión de la literatura / CD30(+)-lymphoproliferative disorders. Report of a 26-case-series and literature review

Introducción. Los síndromes linfoproliferativos que expresan CD30+ en la piel (SLP CD30+) incluyen las formas cutáneas primarias (SLP-CP) CD30+ (papulosis linfomatoide (LyP), linfoma anaplásico a células grandes primario cutáneo (PC-ALCL) y casos borderline) que tienen un buen pronóstico y las secundarias a otro linfoma (linfoma anaplásico de células grandes (ALCL) secundario a micosis fungoide (MF-T), síndrome de Sézary, LyP, enfermedad de Hodgkin), así como tipos infrecuentes de linfomas primarios que expresan este marcador, cuyo comportamiento es más agresivo (leucemia/ linfoma de células T del adulto o el linfoma angiocéntrico cutáneo de células T de la infancia tipo hidroa). También hay que considerar a las infiltraciones cutáneas secundarias a un ALCL sistémico de origen nodal. Es evidente que basándose sólo en los hallazgos histopatológicos es virtualmente imposible diferenciar estas entidades, y por lo tanto los datos de la presentación clínica e incluso muchas veces de la evolución, son cruciales para establecer un diagnóstico definitivo. Objetivos. Describir las características clínicas, histopatológicas y el pronóstico de los pacientes asistidos en la Unidad de Dermatología del Hospital General de Agudos Dr. Cosme Argerich con diagnóstico de SLP CD30+, y realizar una revisión de la literatura. Materiales y métodos. Estudio retrospectivo de revisión de la base de datos de pacientes con diagnóstico histológico e inmunohistoquímico confirmado de SLP CD30+ desde noviembre de 1995 hasta septiembre de 2010. Se evaluó diagnóstico, edad al inicio de la enfermedad, sexo, estadio, tiempo de evolución, respuesta al tratamiento y sobrevida. Resultados. Fueron evaluados 26 pacientes con diagnóstico confirmado de SLP CD30+. De los 26 casos incluidos, 19 (73%) correspondieron a SLP-CP CD30+, 11 (58%) LyP (de las cuales 4 se asociaron a MF), 3 (16%) borderline, y 5 (26%) PC-ALCL...

CD30(+)-lymphoproliferative disorders (CD30(+)-LPD) constitute a heterogeneous groupof neoplasms with different therapeutic approaches and outcomes. They can be primary cutaneous,including lymphomatoid papulosis (LyP), primary cutaneous anaplastic large cell lymphoma (PC-ALCL)andborderlinecases. A second group is secondary to another lymphoma, such as anaplastic large celllymphoma (ALCL) occurring after mycosis fungoides (MF-T), Sezary syndrome, LyP, and Hodgkin’s disease.Another different group of disorders showing CD30(+) expression, not belonging to the groups abovementioned, must be kept in mind in order to perform a differential diagnosis, including rare primarylymphomas, such as adult T cell leukemia/lymphoma, or angiocentric cutaneous T-cell lymphomaof childhood (hydroa-like lymphoma), and secondary skin involvement due to a systemic ALCL. Asdifferential diagnosis among them is virtually impossible based on histologic features alone, data on theclinical presentation and evolution are crucial to establish a correct diagnosis.

Panniculitis in a patient with dermatomyositis.

Panniculitis is a rarely reported clinical finding in dermatomyositis. It may precede the other manifestations associated with dermatomyositis by as much as 14 months. In all cases, myositis and panniculitis improve simultaneously during treatment. The present report describes the case of a 30-year-old female patient with clinical and histopathological findings consistent with panniculitis two months after the onset of the muscle and cutaneous symptoms that permitted diagnosis of dermatomyositis. The skin lesions regressed following steroid treatment.
