The Direct Effect of Magnetic Tape® on Pain and Lower-Extremity Blood Flow in Subjects with Low-Back Pain: A Randomized Clinical Trial.

Low-back pain has a high impact on the world population, and solutions are in demand. The behavior of specific physiological processes has been modified using magnetic fields, whether for pain relief, bone consolidation, or improvement of vascularization. The use of tape with magnetic properties could help in these cases. A double-blind randomized clinical trial was designed to use Magnetic Tape® versus placebo Kinesio tape. Blood flow variables were evaluated using pulsed power Doppler ultrasound. Resistance index, pulsatility index, systolic velocity, and diastolic velocity were measured. The pressure pain threshold was measured using algometry in 22 subjects. The results reveal significant differences between the groups for the pulsation index variable (8.06 [5.16, 20.16] in Magnetic Tape® versus 5.50 [4.56, 6.64] in Kinesio tape) and lower (0.98 [0.92, 1.02] for Magnetic Tape® versus 0.99 [0.95, 1.01] for Kinesio tape) in the resistance index variable. The pressure pain threshold variable presented significant differences at multiple levels. The application of Magnetic Tape® causes immediate effects on blood flow and pain and could be a technique of choice for pain modulation. Further studies would be necessary.

[Gastric tricobezoar: a rare cause of tumoral syndrome and pyloric obstruction]. / Tricobezoar gástrico: una causa poco frecuente de síndrome tumoral y de obstrucción pilórica.

UNLABELLED: A Trichobezoar is a rare tumoral mass of the gastrointestinal tract, formed mainly from the ingestion of hair. It contains also mucus and foods debris. CASE PRESENTATION: A 22 years old female with a 10 years history of surgery secondary to gastric foreign body (trichobezoar), presents with abdominal pain, swelling, nausea and vomiting. Physical examination of the abdomen revealed a palpable mass in the epigastric and left upper quadrant regions. It was also noted areas of alopecia of the scalp. DISCUSSION: Ninety percent of the trichobezoars present in females with a high frequency between 10-19 years. The treatment of bezoars (unless small in size) is mainly surgical. A psychiatric evaluation and follow up is important after surgery hence in most cases there is a psychological disorder that lead to the ingestion of hair.

El tricobezoar es una rara formación tumoral gástrica causada por un cuerpo extraño compuesto fundamentalmente por pelo; también contiene moco y fragmentos de alimentos. Presentación del caso: Paciente de 22 años que hace 10 años fue intervenida por cuerpo extraño gástrico (tricobezoar), ahora refiere cuadro de dolor abdominal, distensión, náuseas y vómitos, al examen físico presencia de masa abdominal palpable en epigástrico y cuadrante superior izquierdo. En la cabeza se observaron zonas alopécicas. Discusión: El 90% de los tricobezoares se presentan en el sexo femenino. Su máxima frecuencia es entre 10 y 19 años. El tratamiento de los bezoares, excepto los más pequeños, es quirúrgico. El control psiquiátrico postoperatorio es fundamental ya que en casi todos los casos existe en el fondo un conflicto afectivo que perpetúa el hábito de ingerir cabello.

Risk factors associated with the development of hyperamylasemia and post-ERCP pancreatitis in the Cuban National Institute.

CONTEXT: Acute pancreatitis is the most common complication in ERCP, and some risk factors were associated with the development of hyperamylasemia and post-ERCP pancreatitis. OBJECTIVES: identifying new factors associated with the development of hyperamylasemia or post-ERCP pancreatitis in patients attended at our center. MATERIAL AND METHODS: A (retrospective) cohort study was carried out in 170 patients on which a diagnostic-therapeutic ERCP was done due to biliopancreatic disease. 67 patients developed hyperamylasemia (39.4%) and 6 post-ERCP pancreatitis (3.5%). The following diagnostic criteria were applied: Hyperamylasemia: increase in the serum amylase level above the normal value (90 I/U). Acute post-ERCP pancreatitis: clinical: continuous abdominal pain for over 24 hours and biochemical: elevation of amylase3 times above normal value (90 U/I). RESULTS: The number of cannulations more than 4 (19 patients), (p=0.006; RR= 3.00) was associated significantly with the development of hyperamylasemia and the placing of biliary stent (14 patients), (p=0.00; RR= 0.39) was a protective factor. The factors associated with the development of post-ERCP pancreatitis were related with the patient (peridiverticular location of the papilla (p=0.00; RR= 2.00) and the sphincter of Oddi dysfunction (p=0.000; RR=1.20). CONCLUSION: Technical factors were associated with the development of hyperamylasemia, however, the factors associated with the development of post-ERCP pancreatitis in our universe of study were related mainly with the patient.

Radiografía por contraste de bario combinada con enteroscopia de doble balón para fines diagnósticos / Barium contrast radiography combined with double balloon enteroscopy for diagnostic purposes

La cápsula endoscópica, la enteroclisis por tomografía computarizada, la radiografía con contraste de bario y la enteroscopia de doble balón constituyen actualmente los estudios más empleados para la exploración completa del intestino delgado. Objetivo: Describir la utilización de la radiografía con contraste de bario y la enteroscopia de doble balón en conjunto como métodos de diagnóstico en las afecciones del intestino delgado. Materiales y métodos: Se realizó un estudio descriptivo, retrospectivo, con 83 radiografías con contraste de bario y 97 enteroscopias de doble balón en 83 registros clínicos de pacientes durante un período de 42 meses, con un rango de edad entre 19 y 82 años (media 45.9± 17.1), y discreto predominio del sexo femenino. Resultados: La anemia y la diarrea crónica fueron las principales indicaciones para ambos estudios. Los principales signos radiológicos patológicos fueron:alteración del patrón mucoso, rigidez de asas, tránsito acelerado y floculación-fragmentación de la columna de bario. La hiperplasia linfoide y la yeyunitis inespecífica resultaron más frecuentes entre los resultados enteroscópicos patológicos. La histología demostró una coincidencia diagnóstica del 82.6 % entre las enfermedades sospechadas por los signos radiológicos y los resultados. Conclusiones: La radiografía con contraste de bario y la enteroscopia de doble balón resultan útiles en conjunto para el tratamiento de las afecciones intestinales...

We are presenting an case of a patient with upper gastrointestinal bleeding presented as hematemesis preceded by profuse vomiting secondary to a duodenal obstruction, caused by an impacted giant biliary stone in the duodenal bulb (Bouveret syndrome). The diagnosis was made during an upper gastrointestinal endoscopy and confirmed by surgery. We report and discuss this case as it is the first presentation in our institution.

Risk factors associated with the development of hyperamylasemia and post-ERCP pancreatitis in the Cuban National Institute / Factores de riesgo con el desarrollo de la hiperamilasemia y pancreatitis post PCRE en el Cuban National Institute

Contexto: La pancreatitis aguda es la complicación más frecuente de la PCRE y algunos factores de riesgo son asociados con el desarrollo de hiperamilasemia y pancreatitis post PCRE. Objetivos: Identificar factores nuevos asociados con hiperamilasemia y pancreatitis post PCRE en pacientes que acudieron a nuestro centro. Material y métodos: Un estudio retrospectivo de cohorte se llevó a cabo en 170 pacientes en quienes se realizó una CPRE diagnóstico-terapéutica por enfermedad biliopancreática. 67 pacientes desarrollaron hiperamilasemia (39,4%) y 6 pancreatitis post PCRE (3,5%). Se aplicaron los siguientes criterios diagnósticos: Hiperamilasemia: elevación de la amilasa sérica por encima del valor normal (90IU).Pancreatitis aguda post PCRE: dolor abdominal continuo por más de 24 horas y elevación de la amilasa tres veces por encima del valor normal. Resultados: El número de canulaciones, más de 4 (19 pacientes), (p=0,006; RR= 3,00) se asoció significativamente con el desarrollo de la hiperamilasemia y la puesta de stents biliares (14 pacientes) se asoció como un factor protector (p=0,00; RR= 0,39). Los factores asociados con el desarrollo de la pancreatitis post PCRE se relacionaron con el paciente (localización peridiverticular de la papila (p=0,00; RR= 2,00) y disfunción del Esfinter de Oddi (p=0,000; RR=1,20). Conclusiones: Factores técnicos fueron asociados con el desarrollo de la hiperamilasemia, sin embargo, los relacionados con el desarrollo de la pancreatitis post PCRE fueron mayoritariamente relacionados al paciente.
