RESUMO
BACKGROUND & AIMS: The septin 9 blood test is indicated for colorectal cancer screening in individuals who decline first-line tests, but participation in this context is unclear. We conducted a randomized controlled trial to compare reoffering colonoscopy and fecal immunochemical test (FIT) alone versus also offering the blood test among individuals who declined colonoscopy and FIT. METHODS: Screen-eligible Veterans aged 50-75 years who declined colonoscopy and FIT within the previous 6 months were randomized to letter and telephone outreach to reoffer screening with colonoscopy/FIT only (control), or additionally offering the blood test as a second-line option (intervention). The primary outcome was completion of any screening test within 6 months. The secondary outcome was completion of a full screening strategy within 6 months, including colonoscopy for those with a positive noninvasive test. RESULTS: Of 359 participants who completed follow-up, 9.6% in the control group and 17.1% in the intervention group completed any screening (7.5% difference; P = .035). Uptake of colonoscopy and FIT was similar in the 2 groups. The full screening strategy was completed in 9.0% and 14.9% in the control and intervention groups, respectively (5.9% difference; P = .084). CONCLUSIONS: Among individuals who previously declined colonoscopy and FIT, offering a blood test as a secondary option increased screening by 7.5% without decreasing uptake of first-line screening options. However, completion of a full screening strategy did not increase. These findings indicate that a blood test is a promising method to improve colorectal cancer screening, but obtaining a timely colonoscopy after a positive noninvasive test remains a challenge (ClincialTrials.gov number, NCT03598166).

The challenges of consenting for procedures are well documented and are compounded when patients have limited English proficiency (LEP). Standardized video consent has been studied, but research in gastroenterology is limited. We created educational videos in English and Spanish covering the elements of traditional consent for colonoscopy and upper endoscopy. All participants underwent traditional verbal consent and a subset viewed the language and procedure specific video. Participants from a multilingual, safety-net hospital patient population were then given a questionnaire to assess their comprehension and satisfaction. Participants who watched the video had higher comprehension scores than those who received traditional verbal consent alone. This difference persisted when data was stratified by language and procedure, and when controlled for educational level and prior procedure. Video consent improves comprehension and satisfaction for endoscopy and may mitigate some of the challenges encountered when consenting patients with LEP.

RESUMEN INTRODUCCIÓN: La ganglionopatía sensitiva es una rara complicación del déficit de vitamina B12, la cual da origen a un espectro de síntomas neurológicos que incluyen alteración de la sensibilidad vibratoria, propiocepción, ataxia y, con menor frecuencia, trastornos del movimiento. La pseudoatetosis es una presentación muy inusual. CASO CLÍNICO: Un paciente masculino de 73 años se presenta con parestesias y torpeza de las cuatro extremidades, dolor tipo urente en plantas de pies y manos, inestabilidad postural y limitación para la marcha. En la exploración neurológica se encuentra hipoestesia y ataxia sensitiva de las cuatro extremidades, con presencia de pseudoatetosis de los miembros superiores como consecuencia de ganglionopatía por déficit de vitamina B12 demostrada por la imagen típica de "V" invertida, debido a compromiso de las proyecciones centrales las neuronas sensitivas mielinizadas en RMN de columna cervicotoráccica. A los cuatro meses se reporta mejoría del déficit propioceptivo y corrección del trastorno de movimiento gracias a la reposición de la cianocobalamina intramuscular. Hasta el momento no se presenta patología neoplásica, autoinmune o infecciosa. CONCLUSIONES: La ganglionopatía sensitiva por déficit de vitamina B12 es una condición potencialmente reversible y subdiagnosticada que puede manifestarse ocasionalmente con trastornos del movimiento. Debe sospecharse en pacientes con déficits sensitivos por compromiso de fibra gruesa. Su pronóstico es favorable si la causa del déficit se documenta tempranamente y se hace reposición de dicha vitamina.
SUMMARY INTRODUCTION: Sensory ganglionopathy is a rare complication of vitamin B12 deficiency, causing an spectrum of neurologic symptoms such as abnormal vibratory sensitivity, proprioception, gait disturbance and rarely movement disorders like pseudoatetosis and dystonia. CLINICAL CASE: A73-year-old man was admitted with numbness and clumsiness of his extremities, burning pain on palms and soles, postural instability and impaired walking. Neurological examination demonstrated hypesthesia and sensory ataxia of four limbs with associated pseudo athetoid movements of the upper limbs as a consequence of ganglionopathy by vitamin B12 deficiency, showing typical MRI inverted "V" sign due to degeneration of central projections from large sensory neurons, which was successfully treated with IM cyanocobalamin 4 months later. CONCLUSIONS: Sensory ganglionopathy in B12 deficit is a potentially reversible and underdiagnosed condition, which occasionally can present with movement disorders. Must be suspected in patiens presenting with sensory deficits depending on richly myelinated axons. Usually with good prognosis after identifying the deficit's cause and giving propper treatment.

BACKGROUND: Sacroiliitis is an inflammatory arthritis of the sacroiliac joints and is associated with inflammatory bowel disease (IBD). Yet, sacroiliitis often goes undiagnosed in IBD, and the clinical association between IBD disease activity and sacroiliitis is not well established. Patients with Crohn's disease (CD) often receive magnetic resonance enterography (MRE) to assess disease activity, affording clinicians the opportunity to evaluate for the presence of sacroiliitis. We aimed to identify the prevalence and disease characteristics associated with sacroiliitis in CD patients undergoing MRE. METHODS: All CD patients undergoing MRE for any indication between 2014 and 2018 at an IBD referral center were identified. The MREs were reviewed for the presence of sacroiliitis based on bone marrow edema (BME) and structural lesions. We analyzed demographics, IBD characteristics, clinical and endoscopic disease activity, and management between CD patients with and without sacroiliitis. RESULTS: Two hundred fifty-eight patients with CD underwent MRE during the study period. Overall, 17% of patients had MR evidence of sacroiliitis, of whom 73% demonstrated bone marrow edema. Female gender, back pain, and later age of CD diagnosis were associated with sacroiliitis (P = 0.05, P < 0.001, P = 0.04, respectively). Disease location and CD therapy were not associated with sacroiliitis on MRE. Clinical, endoscopic, and radiographic disease activity were not associated with sacroiliitis on MRE. CONCLUSION: Sacroiliitis is a common comorbid condition in CD. With limited clinical clues and disease characteristics to suggest sacroiliitis, physicians may utilize MRE to identify sacroiliitis, especially in CD patients with back pain.

INTRODUCTION: Since 2001, device-assisted enteroscopy (DAE) has revolutionized the diagnostic and therapeutic capabilities for managing small bowel pathology. Though commonly performed, there have been no recent large studies to assess the use, yield, and risks of DAE and none that include all 3 DAE modalities. We hypothesized that DAE is safe with high diagnostic and therapeutic yields achieved within reasonable procedure duration and here we present a large retrospective multicenter US study evaluating the use, yield, and complications of DAE. METHODS: After obtaining institutional review board approval, electronic records were used to identify all DAE's performed for luminal small bowel evaluation in adult patients at 4 US referral centers (Duke University Medical Center, New York University Langone Medical Center, Louisiana State University Health Sciences Center, and University of Massachusetts Medical Center) from January 1, 2014 to January 1, 2019. Electronic medical records were reviewed to collect and analyze a variety of procedure-related outcomes. Using the data pooled across centers, descriptive statistics were generated for the patient and procedure-related characteristics and outcomes; relationships between characteristics and outcomes were explored. RESULTS: A total of 1787 DAE's were performed over this 5-year period (392 at Duke University Medical Center, 887 at Louisiana State University Health Sciences Center, 312 at New York University Langone Medical Center, and 195 at University of Massachusetts Medical Center). Of these, there were 1017 (57%) double-balloon, 391 (29%) single-balloon, and 378 (21%) spiral enteroscopies. The mean age of patients undergoing DAE was 66 years and 53% of examinations were performed on women; 18% of patients in the cohort underwent >1 DAE over this time span. A total of 53% of examinations were performed for suspected small bowel bleeding, 31% were directly guided by video capsule endoscopy findings and 8% were performed for abnormal imaging. A total of 85% of examinations used an antegrade approach and DAE took a mean of 45 minutes to complete; 76% of examinations revealed abnormal findings, with vascular, inflammatory, and neoplastic findings seen in 49%, 17%, and 15% of the cohort, respectively. Older age was significantly associated with any abnormal finding, including arteriovenous malformations (P<0.0001); 50% of examinations included a therapeutic maneuver, most commonly argon plasma coagulation/cautery (43%). There were complications in 16 examinations (0.9%) including 2 perforations (0.1%), 6 cases with bleeding (0.3%) and 1 episode of pancreatitis (0.1%). CONCLUSIONS: DAE is most commonly performed to evaluate suspected small bowel bleeding and is commonly directed by video capsule findings. DAE is safe, has a high diagnostic yield, with 76% of examinations showing abnormal findings, and frequently features therapeutic maneuvers. Advancing age is associated with abnormal findings on DAE.

Bleeding from the small bowel can be challenging to identify by endoscopic or radiographic evaluation. We present the case of a patient with incompletely treated latent tuberculosis and medical history of T-cell lymphoma who developed gastrointestinal bleeding because of concurrent Burkitt lymphoma, tuberculosis enteritis, and cytomegalovirus enteritis. The interplay of these 3 diagnoses is discussed.
RESUMO
Tetralogy of Fallot (ToF) treatment is difficult in patients with surgical risk factors or unfavorable anatomy. Stent implantation in the right ventricular outflow tract (RVOT) is an option for these patients. We report our initial experience in Chile with RVOT stenting in patients with ToF. Retrospective and descriptive study conducted in three pediatric cardiovascular centers in Chile between 2012 and 2015, including all ToF patients with stent in the RVOT as first procedure. Clinical records, echocardiographic, interventional, and surgical reports were reviewed for demographics and information of RVOT and pulmonary arteries. 12 newborns with ToF were included (75% female). Median age was 20 days (1-70) and mean weight was 2178 g (1400-3414). Saturations increased after the procedure from 74.3% (55-88) to 88.5% (80-98%), (p < 0.01). No complications or mortality were related to interventions. Follow-up was 11 months (7-36). Median right and left pulmonary arteries Z-score increased from - 4.0 (- 5.2 to - 0.3) and - 1.5 (- 4.8 to - 0.26) to + 0.53 (0.0 to 2.2) and + 1.1 (0.5 to 2.9), (p < 0.05), respectively. Nakata index increased from 63 mm2/mm2 (35 to 143) to 162 mm2/mm2 (107 to 197), (p < 0.05). Surgical repair was performed at a median of 4 months (2-7). Transannular patch repair was necessary in all patients and there was no surgical mortality. RVOT stenting is a safe and useful option for patients with ToF and surgical risk factors or unfavorable anatomy. It increases the pulmonary blood flow, improving saturation and pulmonary artery growth as a bridge for surgical repair.

We report a 59-year-old male who, three weeks after a coronary revascularization surgery, reported a sudden intense burning pain in his left upper limb. Two weeks later, he reports a paresis with difficulty to extend his left wrist and fingers. The electromyography showed a severe axonal damage of the radial nerve with distal denervation signs. This clinical picture probably corresponds to a neuralgic amyotrophy, an inflammatory disorder of the brachial plexus known by a number of terms, including Parsonage-Turner syndrome.

RESUMEN El síndrome neuroléptico maligno (SNM) es una complicación severa de los antipsicóticos, en especial los de primera generación como el haloperidol, que fue el primero en el que se describió esta patología, caracterizada por fiebre, rigidez, alteración del estado de conciencia y disautonomías. Por otro lado, la mielinólisis central pontina (ahora llamada síndrome de desmielinización osmótica) resulta de las alteraciones agudas séricas del sodio, como las que ocurren en las reposiciones de hiponatremia, y podría poner en riesgo la vida al igual que el SNM. La asociación de estas dos patologías es inusual y hasta el momento no se conoce con claridad su relación causal, producto de los pocos casos reportados. Aunque se conoce la mortalidad del síndrome neuroléptico maligno, la compañía de la mielinolisis central pontina podría aumentar la morbimortalidad de esta entidad, por lo cual es necesario reconocerla rápidamente para prevenir la aparición de complicaciones, ya que no cuenta con un tratamiento específico. Presentamos el caso de un paciente joven que cursó con estas dos patologías, y consideramos que la causa de la mielinolisis central pontina fue el haloperidol, así como del SNM. A pesar de ello, este medicamento continúa siendo muy seguro en la práctica clínica ya que la aparición de estas complicaciones es una reacción idiosincrática por algún tipo de susceptibilidad genética desconocida.
SUMMARY Neuroleptic malignant syndrome (NMS) is a severe complication of antipsychotics, especially those of first generation such as haloperidol, which was the first in which this pathology was described, characterized by: fever, rigidity, alteration of the state of consciousness and dysautonomies. On the other side, central pontine myelinolysis (Now Called Osmotic Demyelination Syndrome), search results of acute sodium alterations of sodium, as those occurring in hyponatremia replenings and could put life at risk just like the NMS. The association of these two pathologies is unusual and until now, their causal relationship, the result of the few cases reported, is not clearly known. Although the relationship of the neurological syndrome may be limited, the company of central myelolysis could increase the morbidity of this entity, so it is necessary to be required quickly to prevent the onset of complications, which does not have a specific treatment. We present the case of a young patient who has these pathologies and we consider that the cause of centralized myelinolysis is haloperidol as well as NMS, despite this, this medication continues to be very safe in clinical practice since the appearance of These complications is an idiosyncratic reaction due to some type of unknown genetic susceptibility.

Background: Compared to standard coagulation essays (SCE), such as international normalized ratio (INR), prothrombin activated partial thromboplastin time (aPTT), or platelet count, thromboelastograhy (TEG) offers precise and real-time information about hemostasis. TEG tests both platelet function and coagulation by assaying several parameters of clot formation dynamically in whole blood. Aim: To evaluate hemostasis in cirrhotic patients undergoing liver transplantation and determine the positive and negative predictive values of SCE for alterations of TEG. Material and Methods: Preoperative SCE and TEG were prospectively analyzed in 25 patients. Results were categorized as normal, laboratory alteration or clinical alteration. SCE results were compared with TEG parameters to determine positive (PPV) and negative predictive values (NPV). Results: Hemostasis was abnormal and laboratory abnormalities were observed in all patients. One patient had clinical signs of excessive bleeding. SCE were abnormal in all patients and TEG was normal in nine patients. The most common alteration in TEG was hypocoagulability, in some cases associated with hypercoagulability and hyperfibrinolysis. Two patients had solely hypercoagulability. PPV of INR, aPTT, platelet count and fibrinogenemia were 0, 0, 0.5 and 0.17 respectively. NPV of the same tests were 1, 1, 0.34 and 1 respectively. Conclusions: Hypocoagulability was the most common laboratory alteration, however, clinical signs of coagulopathy were rarely present. SCE had a poor predictive value to diagnose o discard hemostatic abnormalities.

RESUMEN INTRODUCCIÓN: Dentro de los estudios poblacionales el grupo de adultos mayores es el de mayor crecimiento y Colombia no está ajena a dicha tendencia, por tanto el estudio de la cefalea en el adulto mayor (>65 años) es un reto diagnóstico y terapéutico en neurología. Aunque las cefaleas primarias son las más prevalentes, es importante resaltar que hay un incremento de las causas secundarias. OBJETIVO: Determinar la etiología de la cefalea primaria y secundaria en mayores de 65 años y sus características en el Hospital Universitario San José Infantil (HUSJI) de Bogotá en el periodo comprendido entre enero de 2010 y diciembre de 2015. MATERIALES Y MÉTODOS: Se realizó un estudio descriptivo retrospectivo mediante revisión de historias clínicas, en el que se determinaron las causas de cefalea primaria y secundaria según la Clasificación Internacional de Cefalea, tercera edición (IHS) y algunas de sus características. La búsqueda de estos pacientes se realizó mediante el servicio de estadística y epidemiología del hospital así como bases propias del servicio de neurología. RESULTADOS: Se incluyeron 727 pacientes que ingresaron al servicio de urgencias y hospitalización y que fueron valorados por el servicio de neurología, la edad promedio fue de 72,4 años, con una mayor prevalencia de cefalea en mujeres (70,4 %) con respecto a hombres (29,6 %). De estos 352 (48,42 %) cumplían criterios para cefalea primaria (CP) y 375 (51,58 %) para cefalea secundaria (CS). Las causas más frecuentes de cefalea secundaria fue la cefalea atribuida a desórdenes vasculares craneales o cervicales (CADV) 30 %, cefalea atribuida a desórdenes de la homeostasis (CADH) 23 %, cefalea atribuida a desórdenes del cuello (CADC) 15, 7 %. Las causas más frecuentes de cefalea primaria fueron la migraña sin aura (MSA) 34 %, migraña con aura (MCA) 26 % y cefalea tipo tensión (CTT) 21 %. CONCLUSIÓN: En el Hospital San José infantil encontramos una alta frecuencia de cefalea secundaria. Las causas secundarias en especial las vasculares y metabólicas siempre deben ser buscadas en este grupo de pacientes.
SUMMARY INTRODUCTION: Within a population studies, the older adults in one with the greatest, and Colombia is not unaware of this trend. Therefore the study of headache in the elderly (>65 years) is a diagnostic and challenge in neurology .Although the primary headaches are the most prevalent, but it should be noted there is an increase in secondary causes. OBJECTIVE: To determine the etiology of primary and secondary headache in patients over 65 years of age. Materials and methods: Descriptive and retrospective study by reviewing medical records in which the causes of primary and secondary headache were determined according to the International Classification of Headache 3rd Edition (IHS) and some of its characteristics. The search for these patients is done through the hospital statistics and epidemiology service as well as the own bases of the neurology service. RESULTS: Were incluyed 727 patients, the average age was 72.4 years, with a predominance of headache in women (70, 4%); 352 (48.42%) met criteria for primary headache (PC) and 375 (51.58%) for secondary headache (CS). The most frequent causes of CS were Headache attributed to disorders of homeostasis (CADH) 23%, headache attributed to disorders of the neck (CADC) 15, 7%, headache attributed to cranial or cervical vascular disorders (CADV). The most frequent causes of primary headache were migraine without aura (MSA) 34%, migraine with aura (MCA) 26% and headache type tension (CTT) 21%. CONCLUSION: In our group of patients, we found a higher frequency of secondary headache in patients over 65 years of age. Secondary headaches of vascular and homeostatic origin should always be sought in people over 65 years in our hospital.

El síndrome de Melas es una enfermedad de herencia mitocondrial caracterizada por encefalopatía mitocondrial, acidosis láctica y eventos similares a ataque cerebrovascular, secundaria a una mutación en los genes que codifican las proteínas transportadoras de electrones, limitando la producción energética y generando disfunción multiorgánica, que afecta principalmente el sistema músculo esquelético y el sistema nervioso, lo que está en correlación con las características clínicas que presentan los pacientes. El diagnostico se basa en la sospecha clínica, los hallazgos paraclínicos e imagenológicos y la confirmación de la mutación a través del estudio genético. No existe tratamiento específico, se basa únicamente en el manejo sintomático y requiere apoyo multidisciplinario. Presentamos el caso de un paciente con antecedente de Melas, que ingresó por evento cerebrovascular isquémico bioccipital y correlación con hallazgos en neuroimágenes (espectroscopia y tractografía).
Melas syndrome is a disease characterized by mitochondrial inheritance of mitochondrial encephalopathy, lactic acidosis and events like stroke secondary to a mutation in the gene encoding the electron transport proteins limiting energy production and generating multiorgan dysfunction being affected mainly musculoskeletal system and the nervous system which correlates with the clinical characteristics presented by patients. The diagnosis is based on clinical suspicion, laboratory, and imaging findings and confirmation of the mutation through genetic study. No specific treatment is Is available, but symptomatic treatment is needed and requires multidisciplinary support. We report a patient with a history of Melas who who had bioccipital cerebral ischemic event and correlation with findings in neuroimaging (spectroscopy and tractography).
RESUMO
Species complexes in the poroid Hymenochaetaceae are well documented in the temperate areas. Potential species complexes are less known in tropical areas, however. In the last ten years, four phylogenetically and morphologically closely related species of Phellinus (Hymenochaetaceae) were described from various tropical/subtropical areas viz. P. caribaeo-quercicola, P. gabonensis, P. ellipsoideus, and P. castanopsidis They are characterized by cushion-shaped basidiomata, ventricose, commonly hamate hymenial setae, and broadly ellipsoid, thick-walled, pale yellowish basidiospores. Pursuing the studies of this complex, a phylogenetic approach based on DNA sequence data from the nuc rDNA regions ITS1-5.8S-ITS2 (ITS) and partial 28S (including the domains D1, D2, D3) and on part of the translation elongation factor 1-α (tef1, region between exons 4 and 8) revealed three new lineages or phylogenetic species. Two of these phylogenetic species are composed of exclusively on Neotropical specimens. One of them, described below as Phellinus amazonicus sp. nov., is represented by multiple collections originating from Neotropical, lowland, dense, moist forest at the western edge of the Amazon Basin in Ecuador, the Guiana Shield in French Guiana and (more likely) Trinidad. The second Neotropical phylogenetic species is represented in our phylogenetic analyses by a single collection from northeastern Argentina. It is also potentially known from two herbarium specimens originating from southern Brazil, for which no sequence data is available. It is left for now as Phellinus sp. 1, waiting to gather more specimens and DNA sequences data. The third new phylogenetic species is known by a single collection (pure culture) of uncertain origin. It is thought to represent Phellinus setulosus, a Southeast Asian taxa.
