RESUMEN
STUDY DESIGN: Double-blind, randomized, placebo-controlled, parallel-group multicentric phase IIA clinical trial. OBJECTIVE: To assess the safety and tolerability of oral administration of NFX-88 in subjects with chronic spinal cord injury (SCI) and explore its efficacy in pain control. SETTING: A total of 7 spinal cord injury rehabilitation units in Spain. METHODS: A total of 61 adult with traumatic complete or incomplete spinal cord injury (C4-T12 level), were randomised 1:1:1:1 to a placebo, NFX88 1.05 g, 2.1 g, 4.2 g/day for up to 12 weeks. The placebo or NFX-88 was administered as add-on therapy to pre-existing pregabalin (150-300 mg per day). Safety and tolerability were evaluated, and the Visual Analogue Scale (VAS) was the primary measure to explore the efficacy of NFX-88 in pain control. RESULTS: No severe treatment-related adverse effects were reported for any of the four study groups. 44 SCI individuals completed the study and were analysed. The data obtained from the VAS analysis and the PainDETECT Questionnaire (PD-Q) suggested that the combination of NFX88 with pregabalin is more effective than pregabalin with placebo at reducing neuropathic pain (NP) in individuals with SCI and that the dose 2.10 g/day causes the most dramatic pain relief. CONCLUSIONS: NFX88 treatment was found to be highly safe and well tolerated, with the dose of 2.10 g/day being the most effective at causing pain relief. Thus, the promising efficacy of this first-in-class lipid mediator deserves further consideration in future clinical trials.

Introduction The Global Initiative for Obstructive Lung Disease (GOLD) recommends lung cancer screening for patients with Chronic Obstructive Pulmonary Disease (COPD), but data is lacking regarding results of screening in this high-risk population. The main goal of the present work is to explore if lung cancer screening with Low Dose Chest Tomography (LDCT) in people with COPD, allows lung cancer (LC) diagnosis in early stages with survival compatible with curative state. Methods This is a post hoc exploratory analysis. Pamplona International Early Lung Cancer Action Program (P-IELCAP) participants with a GOLD defined obstructive pattern (post bronchodilator FEV1/FVC<0.70) were selected for analysis. The characteristics of those who developed LC and their survival are described. A Cox proportional analysis explored the factors associated with LC diagnosis. Results Eight hundred and sixty-five patients (77% male, 93% in spirometric GOLD stage 1+2) were followed for 102±63 months. LC prevalence was 2.6% at baseline, with an annual LC diagnosis rate of 0.68%. Early-stage tumors predominated (74%) with a median survival (2575th percentiles) of 139 (76185) months. Cumulative tobacco exposure, FEV1%, and emphysema were the main predictors of an LC diagnosis. Eight (11%) patients with COPD had a second LC, most of them in early stage (92%), and 6 (8%) had recurrence. Median survival (2575th percentiles) in these patients was 168 (108191) months. Conclusions Lung cancer screening of selected high-risk participants with COPD allowed the LC diagnosis in early stages with survival compatible with curative state (AU)

Thoracic disc herniation is one of the most therapeutically challenging spine conditions. A myriad of surgical approaches have been described in the literature, including posterior, anterior, and combined techniques. However, transthoracic and retropleural approaches are currently deemed the most effective techniques to successfully obtain anterior decompression. Herein the authors describe a 65-year-old female patient who underwent a transthoracic endoscopic approach to remove a calcified herniated thoracic disc that caused spinal cord compression. Despite having a long learning curve, the surgical technique described herein can be even used in patients with complex and calcified thoracic disc herniations.

Se tomaron todas las medidas correspondientes a un control de foco para esta enfermedad y se potenciaron las acciones de vigilancia y control en la comunidad al realizarse 200 test rápidos IgM/IgG para detectar presencia de circulación viral. Las labores de pesquisa activa de casos sintomáticos respiratorios fueron reforzadas.
ABSTRACT The epidemiological work to control the focus of an event produced by the presence of positive cases to COVID-19 in the Aguada de Pasajeros municipality, Cienfuegos, is presented. Within the epidemiological survey, 50 contacts were detected, four intradomiciliary and 46 extradomiciliary; all were isolated in hospitals for the care of cases and suspects. 50 real-time polymerase chain reaction tests were performed, of which only two were positive for SARS-CoV-2. All the measures corresponding to a focus control for this disease were taken and surveillance and control actions in the community were strengthened by performing 200 rapid IgM / IgG tests to detect the presence of viral circulation. The active investigation of symptomatic respiratory cases was reinforced.
RESUMEN
BACKGROUND: Patients often experience pain as a result of a stroke. However, the mechanism of this pain remains uncertain. Our aim was to investigate the relationship between pressure pain thresholds (PPTs) and disability pain in patients with hemiplegic shoulder pain (HSP). Methods: Twenty-six post-stroke patients (age 53.35 ± 13.09 years) and healthy controls (54.35 ± 12.37 years) participated. We investigated spontaneous shoulder pain, disability pain perception through the shoulder pain and disability index (SPADI), and the PPTs over joint C5-C6, upper trapezius, deltoid, epicondyle, second metacarpal, and tibialis anterior, bilaterally. RESULTS: The analysis of variance (ANOVA) showed significant differences in pain between groups (p < 0.001) and differences in the SPADI (p < 0.001) between groups but not between sides for PPTs over deltoid (group: p = 0.007; side: p = 0.750), epicondyle (group: p = 0.001; side: p = 0.848), and tibialis anterior (group: p < 0.001; side: p = 0.932). Pain in the affected arm was negatively associated with PPTs over the affected epicondyle (p = 0.003) and affected tibialis anterior (p = 0.009). Pain (SPADI) appeared negatively correlated with PPTs over the affected epicondyle (p = 0.047), and disability (SPADI) was negatively associated with PPTs over the affected tibialis anterior (p = 0.041). CONCLUSIONS: Post-stroke patients showed a relationship between widespread pressure pain hypersensitivity with lower PPT levels and pain disability perception, suggesting a central sensitization mediated by bilateral and symmetric pain patterns.
RESUMEN
INTRODUCTION: Strongyloides stercoralis is an intestinal parasitic nematode that causes hyperinfection and/or a dissemination syndrome in hosts, which is often difficult to diagnose. This study aims to compare the diagnostic efficacy of four conventional methods used to diagnose strongyloidiasis with real-time polymerase chain reaction (qPCR) to detect S. stercoralis in fecal samples. METHODS: We analyzed 143 fecal samples collected from Colombian regions with varying degrees of risk for intestinal infections caused by S. stercoralis to assess the validity, performance, overall efficiency, and concordance of the qPCR using a direct stool test, modified Ritchie concentration technique, agar plate culture, and Harada-Mori technique as reference tests. RESULTS: While four fecal samples were positive for S. stercoralis using conventional methods, 32 were positive via qPCR. The diagnostic sensitivity of the qPCR was 75% [95% confidence interval (CI): 20.07-100%], whereas its specificity, negative predictive value, negative likelihood ratio, and Youden's J index were 78.42% (95% CI: 71.22-85.62%), 99.09% (95% CI: 96.86-100%), 0.32 (95% CI: 0.06-1.74), and 0.53, respectively. In addition, the estimated kappa index between the qPCR and the conventional methods was 0.12 (95% CI: -0.020-0.26). CONCLUSIONS: The diagnostic sensitivity of qPCR to detect strongyloidiasis is analogous to that of conventional parasitology methods, with an additional advantage of being capable of identifying the parasite DNA at low sample concentrations.

RESUMEN La fascitis eosinofílica es una enfermedad rara del tejido conectivo que se caracteriza por induración y engrosamiento progresivo y simétrico de la piel y del tejido celular subcutáneo localizado, principalmente, en las extremidades. Además de las manifestaciones cutáneas hay compromiso articular, muscular y, en casos excepcionales, compromiso sistémico. Su diagnóstico se basa en los hallazgos clínicos, eosinofilia en sangre periférica y la toma de una biopsia profunda de piel, que incluya la fascia donde se evidencia un infiltrado compuesto por linfocitos y eosinófilos. El tratamiento de elección son los esteroides sistémicos acompanados de medicamentos inmunosupresores.
ABSTRACT Eosinophilic fasciitis is a rare connective tissue disease. It is characterised by a progressive and symmetrical induration and thickening of the skin and soft tissues of the limbs. In addition to the skin manifestations, the joints and muscles are also involved, and in rare cases there can be systemic involvement. The diagnosis of EF is based on clinical findings, the presence of peripheral blood eosinophilia, and a full-thickness biopsy that should include the deep fascia in order to show the inflammatory infiltration that is mostly composed of lymphocytes and eosinophils. Systemic corticosteroids remain the treatment of choice and may be combined with an immunosuppressive drug.

Se reporta el caso de un hombre de 47 arios con intoxicación crónica por plomo, secundaria a exposición laboral de 5 años, con sintomatología típica de saturnismo. Consultó por debilidad muscular generalizada, disfagia y parestesias en extremidades. Se documentaron altos niveles de plomo en sangre, asociados a neuropatía periférica, confirmada por electromiografía, y disminución de la fuerza muscular en cintura escapular y pélvica (deltoides y vasto medial), así como atrofia de músculos del cuello (flexores y extensores) manifestada como cefaloparesia. Adicional al cuadro de saturnismo se diagnosticó miopatía inflamatoria con base en la elevación de enzimas musculares, miositis por resonancia magnética nuclear y biopsia muscular compatible, siendo, hasta donde se sabe, el primer reporte conocido de la coexistencia de estas 2 enfermedades
A case is presented on a 47-year-old man with chronic lead poisoning with typical symptoms after 5 years of occupational exposure. He consulted for generalised muscle weakness, early dysphagia, cephaloparesia, and paresthesias in upper and lower limbs. He also had atrophy and decreased proximal muscle strength (deltoid and medial vast) and in both flexor and extensor muscles of the neck. He had a history of high blood lead levels and peripheral neuropathy documented by electromyography. In addition to the diagnosis of lead poisoning, inflammatory myopathy was confirmed based on muscle enzyme elevation, muscular inflammation in magnetic resonance imaging, and typical findings in a muscle biopsy. To our knowledge, this is the first report where both conditions are documented in one patient

Introducción: La prevalencia y mortalidad de la infección VIH/sida sigue siendo alta en Colombia, más aún cuando en nuestro sistema el acceso a los programas y terapia antirretroviral es limitado. Objetivo: Describir y analizar las características clínicas, epidemiológicas y sociodemográficas de pacientes hospitalizados con infección por VIH/sida. Metodología: Estudio descriptivo retrospectivo. Resultados: Se incluyeron 159 pacientes, con una edad promedio de 47 ± 13 años, 83% hombres. El 35% tenían antecedentes de promiscuidad sexual, el 27,6% eran homosexuales y el 20% tenían historia de tuberculosis. Al ingreso, un 66% tenía diagnóstico de sida, un 24% recuento de CD4 ≥ 200 cél/mm ³ y un 62% recibía tratamiento antirretroviral. Los principales síntomas al ingreso fueron gastrointestinales (50,3%), neurológicos (40,9%) y respiratorios (30%). En un 33,3% se documentaron infecciones oportunistas, siendo las principales: tuberculosis (37%), histoplasmosis (17%) y criptococosis (9,7%). En un 16,9% se diagnosticaron neoplasias; las más importantes fueron neoplasias de órgano sólido (6,9%), enfermedad linfoproliferativa (5,6%), enfermedad mieloproliferativa (2,5%) y sarcoma de Kaposi (1,8%). La estancia promedio fue de 12 ± 16 días; un 12,5% requirieron atención en UCI, y de estos, un 65% fueron sometidos a ventilación mecánica. La letalidad fue del 13,8%, y la mortalidad atribuible al VIH/sida, del 77,2%. Conclusiones: Las características de nuestra muestra son similares a las reportadas en otras series; difieren en el tipo de infecciones oportunistas y la alta letalidad y mortalidad atribuible a la infección VIH/sida. Las principales causas de hospitalización son infecciones oportunistas, seguidas de enfermedad neoplásica y quirúrgica. Mycobacterium tuberculosis es la infección oportunista más frecuente.
Introduction: The prevalence and mortality of HIV/AIDS infection still high in Colombia, due to a lack of access to HIV programmes and the limited coverage of antiretroviral therapy. Objective: To describe and analyse clinical, epidemiological and socio-demographic features of inpatients with HIV/AIDS infection. Methodology: Descriptive retrospective study. Results: A total of 159 patients were included; the average age was 47 ± 13 years and 83% were men. 35% had a history of sexual promiscuity, 27.6% were men who had sex with men and 20% had a history of tuberculosis. At admission, 66.6% had AIDS, 24% had CD4 ≥ 200 cells/mm ³ and 62% were taking antiretroviral therapy. The most common symptoms at admission were gastrointestinal (50.3%), neurological (40.9%) and respiratory (30%). In 33.3%, opportunistic infections were documented and the most frequent were: tuberculosis (37%), histoplasmosis (17%) and cryptococcosis (9.7%). Some 16.9% of patients had cancer, including 6.91% with a solid organ neoplasm, lymphoproliferative disease (5.6%), myeloproliferative disease (2.5%) and Kaposi's sarcoma (1.8%). The average length of hospitalisation was 12 ± 16 days; some 12.5% required ICU care and 65% required mechanical ventilation. Lethality was 13.8% and attributable mortality to HIV/AIDS infection was 77.2%. Conclusions: The characteristics of our population are similar to those described in other studies; however a high lethality and attributable mortality to HIV/AIDS infection were found. The most frequent causes of hospitalisation were opportunistic infections followed by neoplasms. Mycobacterium tuberculosis was the most common opportunistic infection.

BACKGROUND: The Shoulder Pain Disability Index (SPADI) is a recently published but widely used outcome measure. METHODS: This study included 136 patients with shoulder disorders. SPADI was first translated and back-translated and then subjected to psychometric validation. Participants completed the Spanish versions of the SPADI, general health (SF-12), the Simple Shoulder Test (SST), Disability of Arm, Shoulder, and Hand (DASH) questionnaires and a pain intensity visual analog scale (VAS). RESULTS: The factors explained 62.8 % of the variance, with an internal consistency of α = 0.916 and 0.860, respectively. The confirmatory factor analysis showed a Comparative Fit Index of 0.82 and a Normed Fit Index of 0.80. The Root Mean Square Error of Aproximation was 0.12. The x (2) test for the 2-factor model was significant (x (2) = 185.41, df = 62, p < 0.01). The test-retest reliability was high, with an item ranging of the interclass correlation coefficient (ICC) from 0.89 to 0.93. The ICC for the total score was 0.91 (95 % CI 0.88 to 0.94). Measurement error by minimal detectable change (MDC)95 was 12.2 %. In the construct validity analysis, strong positive correlations were observed between Spanish Version of the SPADI and DASH (pain: r = 0.80; p < 0.01; disability: r = 0.76; p < 0.01). Moderate positive correlations were observed between Spanish Version of the SPADI and VAS (pain: r = 0.67; p < 0.01; disability: r = 0.65; p < 0.01). Moderate negative correlations were obtained between Spanish Version of the SPADI and SST-Sp (pain: r = -0.71; p < 0.01; disability: r = -0.75; p < 0.01). However, pain total Spanish Version of the SPADI was only weakly correlated with physical and mental components of SF-12 (both r = 0.40; p < 0.01). CONCLUSIONS: This Spanish version of SPADI demonstrated satisfactory psychometric properties in a patient sample in the hospital setting.

OBJECTIVE: The objective of this review was to determine whether immune parameters can be modulated by massage after intense physical activity. METHODS: A search was conducted in Pub Med Medline, PEDro, and Cochrane databases, using the key words: "massage", "myofascial release", "acupressure", "recovery", and "warm up" combined with "exercise", "exercise-induced muscle damage", "sport", "immunology", and lymphocytes" independently. Only controlled studies published between 1970 and 2012 were selected, with no restrictions regarding publication language. The CONSORT Declaration was applied to assess the quality of the selected studies. RESULTS: The initial search identified 739 publications in the databases, of which only 5 met the review inclusion criteria. A positive relationship between immunological recovery and post-exercise massage was reported by some of these studies but not by others. CONCLUSION: There is preliminary evidence that massage may modulate immune parameters when applied after exercise, but more research is needed to confirm this possibility.

Antecedentes: Las infecciones por micobacterias no tuberculosas (MNT) se describen en los últimos años con mayor frecuencia, especialmente en pacientes con inmunosupresión y en pacientes tratados por procedimientos estéticos. Las MNT incluyen especies del género Mycobacterium , diferentes del complejo Mycobacterium tuberculosis y Mycobacterium leprae . Objetivo: Describir las características demográficas y clínicas de pacientes hospitalizados con infecciones por MNT. Metodología: Estudio descriptivo retrospectivo. Resultados: De 187 pacientes con infección por micobacterias documentadas por cultivo, 17 (9,1%) tuvieron infección por MNT. Edad promedio de 38,4 ± 19,2 años. El 58,82% fueron hombres. Las principales comorbilidades fueron VIH/sida (41,17%), diabetes mellitus (23,53%), enfermedad renal crónica (17,64%), terapia inmunosupresora (17,64%) y neoplasias (17,64%). En los coinfectados con VIH el recuento de CD4 fue <50 en 85,71%. Las especies más frecuentes fueron complejo M. avium (CMA) 35,29%, M. abscessus (17,65%) y M. chelonae (11,76%). Las formas de infección fueron: diseminada (35,29%), pulmonar (23,53%), piel y tejidos blandos (17,64%) y gastrointestinal (11,76%). Estancia promedio de 22,1 días; un 23,53% requirió atención en UCI. La mortalidad general fue 23,53%. Conclusión: Las infecciones por MNT causan una serie de condiciones patológicas, los pacientes inmunocomprometidos son la población de mayor riesgo y las formas diseminada y pulmonar,las más frecuentes. La sospecha temprana así como la toma de muestras adecuadas y el uso de métodos diagnósticos apropiados son indispensables para su diagnóstico oportuno y tratamiento adecuado.
Background: Nontuberculous mycobacteria (NTM) infections has been described more frequently in recent years, especially in immunosuppression conditions and after cosmetic surgical procedures. The NTM include species of the genus Mycobacterium , other than Mycobacterium tuberculosis complex and Mycobacterium leprae. Objective: To describe the demographic and clinical characteristics of Colombian in-patientswith NTM infections. Methodology: A retrospective descriptive study. Results: In 187 patients with culture- confirmed mycobacterial infection, 17 (9,1%) had NTM.The mean age was 38,4 ± 19,2 and 58,82% were men. Major comorbidities were: HIV/AIDS(41,1%), diabetes mellitus (23,5%), chronic renal disease (17,6%), immunosuppressive therapy(17,6%) and neoplasms (17,6%). In patients co-infected with HIV, CD4 count was <50 in 85,7%.The most frequent species were M. avium complex (MAC) in 35,2%, M. abscessus in 17,6% and M. chelonae in 11,7%. Infections were disseminated (35,2%), pulmonary (23,5%), skin and soft tissue (17,6%) and in gastrointestinal system (11,7%). The average hospital stay was 22,1 day sand 23,5% required intensive care unit. Overall mortality was 23,5%. Conclusion: MNT infections cause a number of pathological conditions, being more frequent in immunocompromised patients. The disseminated and pulmonary forms were the most common. Early clinical suspicion and appropriate samples and diagnostic assays, are crucial for early diagnosis and treatment.

Neutrophils are the first line of defense of the immune system against infection. Among their weaponry, they have the ability to mix and extrude their DNA and bactericidal molecules creating NET-like structures in a unique type of cell death called NETosis. This process is important in order to control extracellular infections limiting collateral damage. Its aberrant function has been implicated in several human diseases including sepsis and autoimmune disease. The purpose of the present paper is to give a general introduction to this concept.
RESUMEN
Introducción y objetivo Evaluar los resultados de nuestro programa de clipaje del sistema nervioso torácico simpático (SNTS) para el tratamiento del rubor facial y/o hiperhidrosis (HH) y comparar la metodología-resultados de la fase de desarrollo del programa (A: enero 2007-abril 2009) y la fase de consolidación del mismo (B: mayo 2009-marzo 2010).Población y métodos Se ha incluido a 44 pacientes (88 procedimientos) sometidos a clipaje videotoracoscópico del SNTS en régimen de cirugía mayor ambulatoria (CMA). Los datos fueron recogidos prospectivamente y analizados retrospectivamente. Se ha realizado estudio estadístico descriptivo y comparativo entre los 2 grupos. Resultados La morbilidad global fue de 5 casos (11,3%). La tasa de recidiva postquirúrgica de HH fue del 4,54% (2 casos), la incidencia de sudoración compensadora (SC) fue del 65,9% (mínima en 26 de los 29 casos). Al comparar el período B con el A, se aprecia: disminución significativa del tiempo quirúrgico, desaparición de la recidiva de HH, disminución de la morbilidad en un 30%, reducción a la mitad de la incidencia de SC moderada-severa e incremento del grado de satisfacción. En uno de los casos de SC mal tolerada se retiraron los clips consiguiéndose la desaparición de esta. Conclusiones El clipaje del SNTS es una técnica segura en régimen de CMA, con una curva de aprendizaje corta (20 casos) tras la cual se obtienen resultados equiparables o, incluso mejores, que los de la simpaticolisis. Estos resultados, junto a su potencial reversibilidad, la convierten, en nuestra opinión, en la técnica de elección en la cirugía del SNTS (AU)

Intrathoracic lymph node enlargement is a common finding in patients with extrathoracic malignancies. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a technique that is commonly used for lung cancer diagnosis and staging but that has not been widely investigated for the diagnosis of enlarged mediastinal and lobar lymph nodes in patients with extrathoracic malignancies. We conducted a retrospective study of 117 patients with extrathoracic malignancies who underwent EBUS-TBNA for diagnosis of intrathoracic lymph node enlargement from October 2005 to December 2009 and compared the EBUS-TBNA findings with the final diagnoses. EBUS-TBNA diagnosed mediastinal metastases in 51 of the 117 (43.6 %) cases and gave an alternate diagnosis or ruled out the presence of malignancy in 35 (56.4 %). Fourteen of these 35 patients underwent further surgical investigation, while the remaining 21 had clinical and radiological follow-up for 18 months. No false negatives were found in the surgery group. In the follow-up group, 13 patients had stable or regressive lymphadenopathy, and eight developed clinicoradiological progression and were assumed to have been false negatives by EBUS-TBNA. The sensitivity and negative predictive value of EBUS-TBNA were 86.4 and 75 %, respectively. Immunohistochemical staining (IHC) was performed in 80.4 % of the samples obtained by EBUS-TBNA. In samples obtained from ten patients with metastatic breast cancer, estrogen receptor expression was successfully assessed in eight patients and progesterone receptor and human epidermal growth factor receptor 2 in four. EBUS-TBNA is an accurate procedure for the diagnosis of thoracic lymph node metastases in patients with extrathoracic malignancies and should be an initial diagnostic tool in these patients. Furthermore, EBUS-TBNA can obtain high-quality specimens from metastatic lymph nodes for use in molecular analyses.

INTRODUCTION AND OBJECTIVE: To evaluate the results of our program of clipping the thoracic sympathetic nervous system (TSNS) for the treatment of facial flush and/or hyperhidrosis (HH), and to compare the methodology-results of the program development phase (A: January 2007-April 2009) and its consolidation phase (B: May 2009-March 2010). MATERIAL AND METHODS: The program included a total of 44 patients (88 procedures) subjected to videothoracoscopy and clipping of the TSNS in a one day surgery unit. Data were collected and analysed retrospectively, and a descriptive and comparative statistical analysis was performed between the two periods (A and B). RESULTS: The overall morbidity was 5 cases (11.3%). The post-surgical occurrence rate of HH was 4.54% (2 cases), and the incidence of compensatory sweating was 65.9% (minimal in 26 of the 29 cases). On comparing period B with period A, there was a significant decrease in surgical time, disappearance of recurrence of HH, a decrease of 30% in morbidity, reduction by half in the incidence of moderate to severe compensatory sweating, and an increase in the level of satisfaction. The clamps were removed in one of the poorly tolerated compensatory sweating cases, resulting in its disappearance. CONCLUSIONS: Clipping the TSNS is a safe technique in the one day surgery unit, with a short learning curve (20 cases) after which comparable, or even better, results are obtained than those of sympatholysis. These results, together with their potential reversibility, makes it, in our opinion, the technique of choice in the surgery of the TSNS.
