ABSTRACT

RESUMEN La resección gástrica atípica ha demostrado ser beneficiosa para tumores submucosos. La técnica pre senta mayor riesgo cuando estos se desarrollan próximos a la unión esófago-gástrica (UEG). Para esta limitación se propuso la resección intragástrica mediante una técnica mixta combinando laparoscopia y endoscopia. En nuestro medio no existen publicaciones al respecto. Se trata de una mujer de 42 años, con lesión subepitelial-subcardial de 2 cm, evaluada mediante videoendoscopia alta (VEDA), compa tible con tumor del estroma gastrointestinal (GIST) evaluado mediante ecoendoscopia. La lesión fue resecada mediante abordaje combinado laparoendoscópico. Bajo visión laparoscópica se introdujeron en cavidad abdominal trocares con balón, y bajo visión endoscópica intragástrica se introdujeron estos en el estómago y se fijó la pared gástrica a la pared abdominal insuflando dichos balones. Posterior mente se realizó la resección de la lesión con sutura mecánica. El abordaje combinado es seguro y eficaz, simple en manos entrenadas, pero constituye una opción reproducible en casos seleccionados.


ABSTRACT Atypical gastric resection has proved to be beneficial to treat submucosal tumors. The technique is more difficult when these tumors develop next to the gastroesophageal junction (GEJ). Intragastric resection combining endoscopic and laparoscopic approach was proposed to solve this limitation. There are no publications about this technique in our environment. A 42-year-old female patients with a 2-mm subepithelial tumor below the cardia evaluated by upper gastrointestinal (UGI) videoendoscopy and endoscopic ultrasound suggestive of a gastrointestinal stroma tumor (GIST) underwent resection using the combined laparo-endoscopic approach. Under laparoscopic guidance, balloon-tipped trocars were introduced in the abdominal cavity and then into the stomach using endoscopic view. The balloons were inflated to fix the gastirc wall to the abdominal wall. The lesion was resected using mechanical stapler. The combined approach is safe and efficient, and simple to perform for trained professionals, constituting a reproducible option in selected cases.

ABSTRACT

Abstract Objective To examine the prevalence of carpal tunnel syndrome in powerlifting athletes with disabilities. Methods The present study evaluated the presence and intensity of pain (numerical scale), nocturnal paresthesia (self-report), and nerve compression (Tinel and Phalen signs) in wheelchair- and non-wheelchair-bound powerlifting athletes with disabilities. The clinical diagnosis of carpal tunnel syndrome was confirmed by the presence of two or more signs/symptoms. Results In total, 29 powerlifting athletes with disabilities were evaluated. None of the athletes reported the presence of pain or nocturnal paresthesia. The Tinel sign was present in 1 (3.45%) wheelchair-bound athlete. A positive Phalen test was present in 3 (10.35%) athletes (1 wheelchair-bound and 2 non-wheelchair-bound). Concurrent positive Tinel sign and Phalen sign tests were found in 2 (6.89%) athletes (1 wheelchair-bound and 1 non-wheelchair-bound). Conclusion Carpal tunnel syndrome was clinically diagnosed in 2 (6.89%) out of 29 powerlifting athletes with disabilities.

ABSTRACT

Resumen Los hongos dematiáceos son un grupo heterogéneo de microorganismos capaces de sintetizar melanina. Las infecciones de este grupo que producen hifas en tejidos se denominan feohifomicosis y generalmente afectan la piel y tejidos vecinos. Presentamos el caso de un varón de 86 años con un tumor quístico blando progresivo en su mano y muñeca derecha, no asociado a dolor o signos inflamatorios. Se demostró una tenosinovitis de los flexores con pseudocapsula y sinovitis adherida a los tendones. El cultivo demostró un hongo dematiáceo compatible con Pleurostomophora richardsiae que se confirmó por secuenciación de la región ITS. La biopsia mostró una inflamación crónica granulomatosa e hifas. Después del drenaje quirúrgico, el paciente fue dado de alta sin terapia antifúngica, pero falleció por causas no relacionadas, tres meses después. Esta es la primera descripción de P. richardsiae como causa de feohifomicosis en Chile. Esta patología se puede sospechar cuando una lesión quística cutánea crónica involucra extremidades sin signos inflamatorios. Puede afectar a pacientes inmunocompetentes o inmunocomprometidos. El tratamiento contempla la escisión quirúrgica con o sin terapia antifúngica.


Abstract Dematiaceous fungi are a heterogeneous group of microorganisms able to synthesize melanin. Infections by this group that provoke tissular hyphae are called phaeohyphomycosis and usually involve skin and neighbor tissues. We present the case of a 86 years old men with a progressive soft cystic tumor in his right hand and wrist not associated to pain or inflammatory signs. A surgical intervention demonstrated flexor tenosynovitis with serous secretion, pseudocapsule and synovitis. Fungal culture demonstrated a dematiaceous fungi compatible with Pleurostomophora richardsiae that was confirmed by sequencing of the ITS region. Biopsy showed chronic inflammation with granuloma and hyphae. After surgical drainage, the patient was discharged without antifungal therapy but died of unrelated causes three month later. This is the first description of P. richardsiae as a cause of phaeohyphomycosis in Chile, a country with a template climate. Phaeohyphomycosis can be suspected when a chronic skin cystic lesion involves extremities without inflammatory signs, sometimes with an associated fistula. It may affect immunocompetent or immunosuppressed patients. Treatment involves surgical excision with or without antifungal therapy and prognosis is favorable.

ABSTRACT

Abstract Objective To investigate the incidence of infection in patients with gunshot-related fractures, and to correlate this finding with the occurrence of surgical debridement in the emergency room. Methods A retrospective, observational, descriptive study that included all cases of fractures caused by firearms between January 2010 and December 2014; 245 fractures in 223 patients were included. Results There was surgical-site infection in 8.5% of the fractures, and the mean number of debridements required to control the infectious process was of 1.273 ± 0.608. A correlation was identified between the surgical treatment chosen and the affected body segment (p< 0.001). The surgical treatment in the emergency room had a correlation with the occurrence of infection (p< 0.001; Chi-squared test). Conclusion Patients with gunshot injuries treated non-operatively presented less severe and stable lesions; thus, the incidence of complications in this group was found to be lower. On the other hand, those patients with complex lesions underwent debridement and external fixation. Therefore, a greater number of infectious complications in patients submitted to external fixation was found, as expected.


Resumo Objetivo Investigar a incidência de infecção em pacientes com fraturas por arma de fogo, e correlacionar esse achado com a ocorrência de desbridamento cirúrgico na sala de emergência. Métodos Estudo retrospectivo, observacional e descritivo, que incluiu todos os casos de fraturas causadas por armas de fogo entre janeiro de 2010 e dezembro de 2014; foram incluídas 245 fraturas em 223 pacientes. Resultados Houve infecção do local cirúrgico em 8,5% das fraturas, e a média de desbridamentos necessários para controlar o processo infeccioso foi de 1,273 ± 0,608. Foi identificada correlação entre o tratamento cirúrgico escolhido e o segmento corporal afetado (p< 0,001). O tratamento cirúrgico na sala de emergência teve correlação com a ocorrência de infecção (p< 0,001; teste do qui-quadrado). Conclusão Pacientes com ferimentos à bala tratados de forma não operatória apresentaram lesões menos graves e estáveis; portanto, a incidência de complicações nesse grupo foi menor. Por outro lado, os pacientes com lesões complexas foram aqueles submetidos a desbridamento e fixação externa. Portanto, como esperado, foi encontrado um maior número de complicações infecciosas em pacientes submetidos à fixação externa.

ABSTRACT

RESUMEN: Las conexiones intertendinosas (CIT) son bandas estrechas de tejido conectivo que unen tendones adyacentes del músculo extensor de los dedos. Dichas bandas se ubican de manera superficial en el dorso del segundo, tercer y cuarto espacios intermetacarpianos (EIMC) presentando funciones importantes como colaborar en la estabilización de la articulación metacarpofalángica y permitir la redistribución de fuerzas extensoras sobre esta articulación. El objetivo del presente estudio fue establecer la biometría de las CIT. Para ello se utilizaron 24 miembros superiores formolizados, pertenecientes al laboratorio de Anatomía, de la Universidad Andrés Bello, sede Viña del Mar, Chile. Se registraron las longitudes de inserción lateral y medial, el ancho y la longitud total de cada CIT. Siguiendo dos criterios, las CIT se clasificaron según morfología y además se localizaron según tercios del dorso de la mano. De las 69 CIT encontradas, el 39 % presentó una disposición transversa y 61 % una oblicua. En relación a la clasificación morfológica de la CIT se identificó un 29 % del tipo 1; 39 % del tipo 2. Para el caso del tipo 3, un 20 % presentó la forma "r" y en un 12 % la forma "y". Respecto a su localización se estableció que en el segundo EIMC el 18 % de las CIT se ubicaron el tercio distal del dorso y el 82 % en el tercio medio. En el tercer EIMC el 96 % de las CIT se localizó en el tercio distal y 4 % en el tercio medio. En el cuarto EIMC el 96 % se ubicó en el tercio distal y el 4 % en el tercio medio. Considerando como referencia la línea biestiloidea, las CIT en el segundo EIMC presentaron un promedio de ancho de 8,16 ± 1,94 mm y una longitud total promedio de 13,71 ± 4,70 mm. En el tercer EIMC, un promedio de 10,94 ± 4,39 mm para el ancho y 6,29 ± 3,26 mm de longitud total promedio. En el cuarto EIMC el promedio de ancho fue de 7,00 ± 3,06 mm y la longitud total promedio 7,08 ± 4,42 mm. Estos hallazgos aportan datos respecto de la biometría y localización de las CIT, lo que resulta de utilidad en procedimientos de reparación quirúrgica del dorso de la mano humana.


SUMMARY: Intertendinous connections (IC) are narrow connective tissue bands extending between the extensor digitorum (ED) tendons. These bands are located superficially on the dorsum of the second, third and fourth intermetacarpal (IMC) space, presenting important functions such as collaborating in the stabilization of the metacarpophalangeal joint (MCP) and allowing the redistribution of extensor forces on this joint. The objective of the present study was to establish the biometric characteristics of IC. To do this, 24 formalized upper limbs are used, belonging to the Anatomy laboratory of the Universidad Andrés Bello, Viña del Mar, Chile. Lateral and medial insertion lengths, width and total length of each IC were recorded. Following two criteria, IC were classified according to morphology and were also located according to thirds of the back of the hand. 69 IC were found, 39% presented a transverse arrangement and 61 % an oblique arrangement. In relation to the morphological classification of IC, 29 % of type 1 were identified, 39 % of type 2. In the case of type 3, 20 % presented the form "r" and 12 % the form "y". Regarding its location, it was established that in the second IMC space, 18 % of the IC were located in the distal third of the back and 82 % in the middle third. In the third IMC space, 96 % of the IC was located in the distal third and 4 % in the middle third. In the fourth IMC space, 96 % were located in the distal third and 4 % in the middle third. Considering the biestiloid line as a reference, the IC in the second IMC space considers an average width of 8.16 + 1.94 mm and an average total length of 13.71 + 4.70 mm. In the third IMC space, an average of 10.94 + 4.39 mm for the width and 6.29 + 3.26 mm of average total length. In the fourth IMC space the average total width of 7.00 + 3.06 mm and the average total length of 7.08 + 4.42 mm. These findings provide data regarding the biometrics and location of IC, which is useful in surgical repair procedures on the back of the human hand.

ABSTRACT

RESUMEN: La comunicación Ulnar-Mediano Palmar Profunda (CUMPP) es la conexión entre la rama profunda del nervio ulnar (NU) y la rama del nervio mediano (NM) que inerva a los músculos tenares como la cabeza superficial del flexor corto del pulgar. Son escasos los trabajos que se ocupan de esta rama comunicante, y su prevalencia es reportada con una amplia variabilidad, en un rango del 16-77 %. Este estudio no probabilístico, descriptivo, transversal, evaluó la frecuencia y características morfológicas de la CUMPP en 106 manos de especímenes cadavéricos frescos no reclamados, a quienes se les practicó necropsia en el Instituto de Medicina Legal de Bucaramanga (Colombia). Se observó rama comunicante CUMPP en 39 especímenes (50,2 %), de los cuales 12 (44,5 %) fueron bilate- rales, 15 (55,6 %) unilaterales, con predominio unilateral derecho para 9 casos (60 %), sobre el izquierdo de tan solo 6 casos (40 %). No se evidenciaron diferencias estadísticamente significativas con relación al lado de presentación (P=0,223). En 21 especímenes (54 %) se observó el tipo IV; mientras que el tipo I fue encontrado en 4 casos (10 %). El promedio de la longitud de la rama comunicante fue de 24,67 DE 6,46 mm; mientras que la distancia del punto proximal de la CUMPP al surco distal del carpo fue de 41,4 DE 2,6 mm. Nuestros hallazgos no son concordantes con lo reportado en la mayoría de estudios previos. Diversos factores como el tamaño de las muestras, las diferentes metodologías de medición y las expresiones fenotípicas de cada grupo de población evaluado, pueden explicar la variabilidad de la CUMPP.


SUMMARY: Deep Palmar Ulnar-Medium Communication (DPUMC) is the connection between the deep branch of the ulnar nerve (UN) and the median nerve (MN) branch, that innervates the thenar muscles as the superficial head of the short flexor of the thumb. Few studies dealing with this communicating branch, and its prevalence is reported with a wide variability in the range of 16-77 %. This non-probabilistic, descriptive, cross-sectional study; evaluated the frequency and morphological characteristics of DPUMC in 106 hands of fresh unclaimed cadaveric specimens, that underwent necropsy at the Institute of Legal Medicine of Bucaramanga (Colombia). DPUMC communicating branch was observed in 39 specimens (50.2 %), of which 12 (44.5 %) were bilateral, 15 (55.6 %) unilateral, with right unilateral predominance for 9 cases (60 %), on the left of only 6 cases (40 %). There were no statistically significant differences in relation to the presentation side (P = 0.223). In 21 specimens (54%), type IV was observed; while type I was found in 4 cases (10%). The average length of the communicating branch was 24.67 SD 6.46 mm; while the distance from the proximal point of the DPUMC to the distal carpal groove was 41.4 SD 2.6 mm. Our findings are not consistent with those reported in most previous studies. Various factors such as sample size, different measurement methodologies and phenotypic expressions of each population group evaluated can explain the variability of the DPUMC.

ABSTRACT

Los músculos lumbricales (ML) de la mano humana son claves en la propiocepción de la flexoextensión de los dedos. La descripción de su inervación indica que el nervio mediano (NM) inerva los dos ML laterales (L1 y L2) y el nervio ulnar (NU) los ML mediales (L3 y L4). Diversos autores han reportado una gran variabilidad de esta inervación, tanto en los nervios que entregan ramos para estos músculos, como también en la distribución de sus ramos y la presencia de troncos comunes. Por otra parte, el número de ramos que recibe cada ML y los puntos motores (Pm) de los mismos ha sido escasamente reportado. El objetivo de este estudio fue determinar número, ubicación y Pm de los ramos destinados a los ML de la mano humana. Así mismo se estableció el patrón de inervación más frecuente. Para ello se utilizaron 24 manos formalizadas, pertenecientes al laboratorio de Anatomía, de la Universidad Andrés Bello, sede Viña del Mar, Chile. Se realizó una disección convencional por planos de profundidad. En todos los casos, el ramo del músculo L1 se originó del nervio digital palmar propio lateral del dedo índice, de la misma forma, en el 100 % el L2 fue inervado por un ramo del nervio digital palmar común del segundo espacio interóseo. En relación a los ML mediales en un 100 % ambos músculos fueron inervados por ramos del ramo profundo del NU (RPNM). En el caso del L3 en un 92 % se presentó un tronco común con el segundo músculo interóseo palmar, asimismo para L4 existió un tronco común con el tercer músculo interóseo palmar en un 79 %. En el 29 %, el L3 presentó una inervación dual. Considerando como referencia la línea biestiloidea, los Pm de los ramos del NM fue de 63,96 mm para L1; 67,91 mm para L2 y 68,69 mm para L3. Para los ramos provenientes del RPNU fue de 69,87 mm para L3 y 69, 21 mm para L4. Los resultados obtenidos aportan al conocimiento anatómico de la inervación de los músculos lumbricales y es de utilidad en procedimientos de neurocirugía que busquen la restauración de la funcionalidad de la mano.


The lumbrical muscles (LM) of the human hand are key in proprioception of flexion and finger extension. The description of its innervation indicates that the median nerve (MN) innervates the two lateral LMs (L1 and L2) and the ulnar nerve (UN) the medial LMs (L3 and L4). Various authors have reported a great variability of this innervation, both in which nerve delivers branches for these muscles, as well as in the distribution of their branches and the presence of common trunks. On the other hand, the number of branches that each LM receives and the motor points (Mp) of these have been scarcely reported. The aim of this study was to determine the number, location and Mp of the branches destined for the LM of the human hand. Likewise, the most frequent innervation pattern was established. For this, 24 formalized hands, belonging to the anatomy laboratory, of the Universidad Andrés Bello, Viña del Mar, Chile, were used. Conventional depth plane dissection was performed. In all cases, the branch of the L1 muscle originated from the palmar digital nerve proper to the index finger, in the same way, in 100 % the L2 was supplied with a branch of the common palmar digital nerve from the second interosseous space. In relation to the LM, in 100 % both muscles were innervated by branches of the deep branch of the UN (DBUN). In the case of L3, 92 % presented a common trunk with the second palmar interosseous muscle. Likewise, in 79 % of the cases, there was a common trunk between the L4 and the third palmar interosseous muscle. In 29 %, the L3 presented a dual innervation. The distance between of the Mp-BEstL was 63.96 mm for L1, 67.91 mm for L2 and 68.69 mm for L3. This distance was 69.87 mm for L3 and 69, 21 mm for L4. The results obtained contribute to the anatomical knowledge of the innervation of the lumbrical muscles and is useful in neurosurgery procedures that seek to restore the functionality of the hand.

ABSTRACT

The aim of this study is to investigate rs1805086 and rs1805065 polymorphisms of MSTN gene of national and amateur Turkish arm wrestlers and people leading a sedentary lifestyle, and the anthropometric properties such as hand, wrist, and forearm circumferences of national and amateur Turkish arm wrestlers are aimed to be explored. In this study, a total of 79 volunteers who were 24 national (7 females, 17 males) Turkish arm wrestlers, 21 amateur (7 females, 14 males) Turkish arm wrestlers and 34 sedentary people (12 females, 22 males) participated. To analyse the data, Statistical Package for the Social Sciences, SPSS 22 (SPSS Inc., Chicago, IL, USA) was used. As a result of the study, when data on rs1805086 and rs1805065 polymorphisms of MSTN gene were examined respectively, it was found out that MSTN 153KK genotype was 100.0% dominant in both national (n=24) and amateur (n=21) arm wrestlers, and it was 94.12 % dominant in sedentary people. KR genotype was observed in 5.88 % of the sedentary people. The data from the other rs1805065 polymorphism of MSTN gene showed that all participants (n = 45, 100.0 %) were carriers of normal homozygous genotype. Furthermore, for both female group and male group, there found to be statistically significant difference in terms of anthropometric properties. It can be concluded that though there was no significant difference between national and amateur Turkish arm wrestlers in terms of their MSTN gene characteristics; in terms of anthropometric properties, significant differences were discovered. It was found out that on these athletes, not MSTN gene polymorphisms but anthropometric properties were effective.


El objetivo de este estudio fue investigar los polimorfismos rs1805086 y rs1805065 del gen MSTN de luchadores de brazos turcos, nacionales y aficionados, y personas que llevan un estilo de vida sedentario, y las propiedades antropométricas además de las circunferencias de manos, muñecas y antebrazos de los luchadores de brazos turcos nacionales y aficionados. En este estudio, participaron un total de 79 voluntarios: 24 luchadores de brazos turcos nacionales (7 mujeres, 17 hombres), 21 luchadores de brazos turcos aficionados (7 mujeres, 14 hombres) y 34 personas sedentarias (12 mujeres, 22 hombres). Para analizar los datos, se utilizó el Paquete Estadístico para las Ciencias Sociales, SPSS 22 (SPSS Inc., Chicago, IL, EE. UU.). Como resultado del estudio, cuando se examinaron los datos sobre los polimorfismos rs1805086 y rs1805065 del gen MSTN respectivamente, se descubrió que el genotipo MSTN 153KK era 100,0 % dominante en luchadores de brazos nacionales (n = 24) y aficionados (n = 21) , y era 94,12 % dominante en personas sedentarias. El genotipo KR se observó en el 5,88 % de las personas sedentarias. Los datos del otro polimorfismo rs1805065 del gen MSTN mostraron que todos los participantes (n = 45; 100,0 %) eran portadores del genotipo homocigoto normal. Además, tanto para el grupo femenino como para el masculino, se encontró una diferencia estadísticamente significativa en términos de propiedades antropométricas. Se puede concluir que, aunque no hubo una diferencia significativa entre los luchadores de brazos turcos nacionales y aficionados en términos de sus características genéticas MSTN; en términos de propiedades antropométricas, se descubrieron diferencias significativas. Se descubrió que, en estos atletas, no fueron los polimorfismos del gen MSTN sino las propiedades antropométricas las efectivas.

ABSTRACT

El arco palmar superficial (APS) resulta de la unión de la arteria ulnar y la rama palmar superficial de la arteria radial. Por su convexidad nacen las arterias digitales comunes. Esta descripción es la única que distintos autores han tomado como válida, por lo que se espera encontrarla durante la disección con mayor frecuencia. Esto no ha sido verificado en nuestra experiencia. Nos proponemos llevar a cabo una revisión de la descripción del APS poniéndolo en contraposición con las disecciones realizadas. Se disecaron y analizaron 61 manos cadavéricas. Estudio del arco palmar superficial: Variante clásica del APS: 23 casos (37,7 %). Variante no clásica del APS: 15 casos (24,6 %). Tipo A: 13 casos (86,7 %). Anastomosis entre arterias ulnar y metacarpiana dorsal del primer espacio. Tipo B: 2 casos (13,3 %). Anastomosis entre arterias ulnar y satélite del nervio mediano. Ausencia del arco: 23 casos (37,7 %) Tipo A: 19 casos (82,6 %). La arteria ulnar es la única estructura en el plano del APS. Tipo B: 3 casos (13 %). La arteria ulnar y la rama palmar superficial de la arteria radial están en el plano del APS sin anastomosarse entre sí. Tipo C: 1 caso (4,4 %). La arteria ulnar y la satélite del nervio mediano están en el plano del APS sin anastomosarse. Estudio de la quinta arteria digital palmar común: La quinta arteria digital palmar común se originó de las distintas variantes en 41 casos (67,2 %). Recomendamos al momento de la disección considerar que: la variante clásica no es la más frecuente de hallar; la ausencia del arco se verifica en el mismo porcentaje que la variante clásica; incluso cuando se comprueba la presencia del APS, el porcentaje de la variante no clásica es contundente; la quinta arteria digital palmar común es una rama colateral constante del APS.


The superficial palmar arch (SPA) is formed by the union of the ulnar artery and the superficial palmar branch of the radial artery. From its convexity four branches emerge, known as the common palmar digital arteries. We propose to carry out a review of the description of the SPA in contrast to the dissections carried out. Sixty-one hands were dissected and studied. Analysis of the SPA: Classic variant of the SPA: 23 cases (37.7 %). Nonclassic variant of the SPA: 15 cases (24.6 %). Type A: 13 cases (86.7 %). Anastomosis between the ulnar artery and the first dorsal metacarpal artery. Type B: 2 cases (13.3 %). Anastomosis between the ulnar artery and the satellite artery of the median nerve. Absence of the arch: 23 cases (37.7 %) Type A: 19 cases (82.6 %). The ulnar artery is the only one present in the plane of the SPA. Type B: 3 cases (13 %). The ulnar artery and the superficial palmar branch of the radial artery are in the plane of the superficial palmar arch, there is no anastomosis between them. Type C: 1 case (4.4 %). The ulnar artery and the satellite artery for the median nerve are in the plane of the SPA, there is no anastomosis between them. Analysis of the fifth common palmar digital artery: The fifth common palmar digital artery originates from the different variants in 41 cases (67.2 %). Based on the results, we recommend at the time of dissecting consider that: The classic variant is not the most frequent to find. The absence of the arch is verified in the same percentage rate as the classic variant. Even when the SPA is present, the percentage rate of the non-classic variant is significant. The fifth common palmar digital artery is a constant collateral branch of the superficial palmar arch.

ABSTRACT

Introducción: este artículo presenta la predicción de tres tipos de movimientos básicos de la mano mediante un algoritmo inteligente para extraer características imprescindibles para el reconocimiento de patrones de movimiento a partir del análisis de señales electromiográficas superficiales adquiridas con el dispositivo Myo. Objetivo: reconocer y predecir patrones básicos de movimiento de la articulación del brazo utilizando electromiografía de superficie para aplicarlo sobre un prototipo de prótesis. Métodos: se tomaron datos de 13 estudiantes de 22 y 23 años de la Universidad Politécnica Salesiana, cada uno de los cuales ejecutó tres tipos de agarre: cilíndrico, pinza y pinza planar. Se trabajó con una frecuencia de 10 Hz y se tomaron 5 muestras por tipo de agarre durante 60 segundos. Para el análisis estadístico de los datos se utilizó la herramienta Anova, estableciendo un valor de significancia mayor a 0,65. Resultados: En ciertos voluntarios hay una mayor reacción en el electrodo 1 debido a que su antebrazo es mayor. El tiempo de respuesta para el reconocimiento varía dependiendo del número de variables que se tenga que comparar. Cuando se analiza un solo movimiento es de 2,6 segundos, en cambio, cuando se analizan los 3 movimientos el tiempo de respuesta incrementa a 7,8 segundos por la cantidad de electrodos que se quieran analizar. Conclusiones: la respuesta del sistema propuesto empieza a ser más lenta a medida que se analizan más movimientos a la vez y por tanto, es menos efectiva. El tiempo de ejecución y respuesta de nuestro sistema, en comparación al estado del arte, es más alto, debido a que se utilizan menos métodos de caracterización de la señal. Adicionalemtne, una limitante del proyecto es la frecuencia de muestreo del dispositivo Myo (200Hz)(AU)


Introduction: the paper presents the prediction of three basic hand movement types by means of a smart algorithm to draw characteristics indispensable for identification of movement patterns based on the analysis of surface electromyographic signals obtained with the Myo device. Objective: recognize and predict basic movement patterns of the arm joint using surface electromyography with a view to applying them over a prosthesis prototype. Methods: data were taken from 13 students aged 22 and 23 years from the Salesian Polytechnic University, each of whom performed three types of grasp: cylindrical, pincer and palmar pincer. A 10 Hz frequency was used and 5 samples were taken of each grasp type during 60 seconds. Statistical analysis was performed with the tool ANOVA, establishing a significance value > 0.65. Results: in certain volunteers a greater reaction was observed in electrode 1, due to their larger forearms. Response time for identification varies with the number of variables to be compared. When only one movement is analyzed, response time is 2.6 seconds, but when the three movements are examined it rises to 7.8 seconds by the number of electrodes intended to be studied. Conclusions: the response of the system proposed starts to slow down as more movements are analyzed simultaneously, which makes it less effective. The performance and response time of our system is higher than in state-of-the-art systems, since fewer signal characterization methods are used. On the other hand, a limitation of the project is the sampling frequency of the Myo device (200 Hz)(AU)

ABSTRACT

Resumen: Objetivo: Describir el efecto de la prótesis impresa en 3D Cyborg Beast en la funcionalidad de miembros superiores (MMSS) en adolescentes con amputación congénita parcial de mano. Casos Clínicos: Se seleccionaron 5 pacientes entre 12 y 17 años con amputación congénita parcial de mano en el Instituto Teletón Santiago. Los pacientes fueron entrenados en el uso de la prótesis por 4 sesiones. Se evaluó la función basal (sin prótesis), al mes y los 4 meses de uso de la prótesis con la pauta Bilan 400 points modificada y la percepción de funcionalidad de MMSS sin y con prótesis con la "Upper Extremity Function Index (UEFI)". Al mes y 4 meses de uso, el porcentaje de cambio para funcionalidad de mano fue de -11% y -4% para la extremidad no afectada y de -9% y -2% para la afectada. El porcentaje de cambio para la percepción de funcionalidad de MMSS fue de -62%. Conclusiones: El uso de la prótesis de mano Cyborg Beast no fue una solución funcional para los 5 pacientes incluidos en este estudio. Futuras investigaciones son necesarias para poder mejorar la funcionalidad de estos diseños de prótesis impresa en tecnología 3D.


Abstract: Objective: To describe the effect of the 3D-printed Cyborg Beast prosthesis on upper limbs function in adolescents with congenital hand amputation. Clinical Cases: Five patients aged between 12 and 17 years, with congenital hand amputation were selected. All patients were from the Teletón Institute in Santiago, Chile. The patients were trained for prosthesis use in four sessions. Hand function was evaluated without prosthesis, at 1 and 4 months of use with the modified Bilan 400 points scale, and upper limb function perception was evaluated with the 'Upper Extremity Functional Index (UEFI)'. At 1 month and 4 months of use, the percentage change for hand functionality for the unaffected limbs was between -11% and -4%; and -9% and -2% for the affected limb. The percentage change for the upper limbs perceived function was -62%. Conclusions: The use of the 3D-printed Cyborg Beast prosthesis was not a functional solution for the 5 patients included in this study. Future research is needed to improve the functionality of these types of 3D-printed hand prostheses.

ABSTRACT

Resumen El síndrome compartimental agudo (SCA) es el aumento de la presión en un espacio osteofascial cerrado. Esto reduce la presión capilar bajo el nivel necesario para la viabilidad de los tejidos del compartimento. El SCA de mano como complicación de un loxoscelismo cutáneo (LC) de predominio edematoso es muy poco frecuente. Presentamos el caso de una mujer de 22 años que presentó un SCA de la mano secundario a un LC y que requirió tratamiento quirúrgico de urgencia mediante una fasciotomía dorsal y palmar.


Abstract Acute compartment syndrome (ACS) is the increase of pressure in a closed osteofascial space. This reduces capillary perfusion below the level necessary for tissue viability. Injury could be irreversible if proper treatment is not performed. Hand ACS secondary to cutaneous loxoscelism with edematous predominance is extremely infrequent. We present a clinical case of a 22-year-old patient who started a hand compartment syndrome secondary to cutaneous loxoscelism (CL), requiring emergency surgical treatment with dorsal and palmar fasciotomy.

ABSTRACT

SUMMARY: Photogrammetry is becoming increasingly popular in morphological research and teaching due to its portability, ability to reliably render 3D models, and quality-to-price relationship relative to some popular surface scanners. Compared to surface scanners, however, the learning process in photogrammetry can be very time consuming. Here we describe common mistakes of photo capture in close-range photogrammetry that greatly affect 3D output and tips to improve them. Problems were identified after the 3D model construction of 780 hand bones of chimpanzees and gorillas from museum collections. Their hands are composed of 27 bones which vary in length and complexity. We show how lighting, object position and orientation, camera angle, and background affect the 3D output. By taking these factors into account, time and error rates for beginners can be greatly reduced and 3D model quality can be considerably improved.


RESUMEN: La fotogrametría está siendo cada vez más popular en la investigación y enseñanza morfológica. Esto debido a su portabilidad, confiabilidad de los modelos 3D y buena relación calidadprecio. Comparada con los escáneres de superficie, sin embargo, el proceso de aprendizaje de la fotogrametría puede llevar mucho tiempo. Aquí se describen errores comunes en la toma de fotos para fotogrametería que afectan de manera importante la creación de los modelos 3D, así como consejos para superarlos. Los problemas descritos fueron identificados luego de la construcción de 780 modelos 3D de huesos de la mano de chimpancés y gorillas depositados en distintas colecciones de museos. Las manos de estas especies están compuestas por 27 huesos que varían en tamaño y complejidad. En este artículo mostramos como la luz, la posición y orientación del objeto, el ángulo de la cámara y el fondo de la imagen afectan el resultado en 3D. Considerando estos factores, personas que están aprendiendo esta técnica pueden reducir de manera importante el tiempo y la probabilidad de error, y mejorar considerablemente la calidad de los modelos 3D.

ABSTRACT

Se estudió el arco venoso dorsal de la mano (AVD) en una muestra de la población de Bucaramanga en 54 mujeres y 50 hombres. Las variables estudiadas en el AVD fueron: número de venas que lo forman, número de venas que recorren su interior, presencia de una vena que forme su parte lateral y medial, conformación cerrada o discontinua del AVD, si la vena metacarpiana del primer dedo se unía al AVD y contribuía a la formación de la vena cefálica, si la vena metacarpiana del quinto dedo se unía al AVD y contribuía a la formación de la vena basílica. También se revisó la concordancia entre la vena que escogían dos observadores independientes, como la más adecuada para venopunción. La comparación con los textos clásicos de anatomía evidenció concordancia en que cerca de la cabeza de los metacarpianos se forman venas metacarpianas dorsales, pero, no siempre estas venas se unen de forma completa para formar un "arco venoso cerrado" como lo describen los esquemas de la mayoría de los autores. Sólo un 41,8 % fueron AVD cerrados. Las venas metacarpianas del primer y del quinto dedo se unieron al AVD en un 44,23 % y un 89,42 % respectivamente. Este dato, sumado al hecho de que en el primer y quinto dedos pueden existir más de una vena que drene su sangre, las cuales no siempre se unen al AVD, ayudan a explicar la razón de porqué en otros estudios se describe ausencia de venas cefálica o basílica o presencia de varias venas cefálicas que permiten la formación de ciertos patrones de la fosa cubital. Se encontró concordancia del 78,85 % en cuanto a la vena escogida para posible venopunción y en el análisis bivariado, hubo asociación estadística de esta concordancia al cruzarla con el número de venas que recorren el interior del AVD.


The dorsal venous arch of the hand (AVD) was studied in a sample of the Bucaramanga population of 54 women and 50 men. The variables studied in the AVD were: Number of veins that form it, number of veins that run through its interior, presence of a vein that forms its lateral and medial part, closed or discontinuous conformation of the AVD, if the metacarpal vein of the first finger joined the AVD and contributed to the formation of the cephalic vein, if the metacarpal vein of the fifth finger joined the ADL and contributed to the formation of the basilic vein. The concordance between the vein chosen by two independent observers was also reviewed, as the most suitable for venipuncture. The comparison with the classic anatomy texts showed concordance in which dorsal metacarpal veins are formed near the metacarpal head, but these veins do not always unite completely to form a "closed venous arch" as described in metacarpal diagrams by most authors. Only 41.8 % were closed AVD. The metacarpal veins of the first and fifth toes joined the AVD in 44.23 % and 89.42 % respectively. This fact, in addition that in the first and fifth fingers, there may be more than one vein draining the blood, which do not always bind to the AVD, helps explain the reason other studies describe absence of cephalic veins, basilica or presence of several cephalic veins that allow the formation of certain patterns of the cubital fossa. There was 78.85 % agreement regarding the vein chosen for possible venipuncture and in the bivariate analysis, there was a statistical association of this concordance when crossing it with the number of veins that run through the interior of the AVD.

ABSTRACT

Abstract Soft-tissue tumors are rare in the pediatric population. First described in 1969 as myxoma of the nerve sheath, the neurothekeoma is a benign tumor lesion with presumable origin in the nerve sheath. It occurs mainly in female children and presents as a mass of slow, subcutaneous growth, asymptomatic and without alteration of the local pigmentation. It is predominantly located in the head, neck, and extremities of the upper limbs. This report presents the case of a 16-year-old male with a tumor mass originating from the nerve sheath in the 4th left metacarpal, intraosseous, and relapsed after previous surgical resection 2 years before this observation. A marginal resection of the tumor mass was performed on the distal region of the fourth metacarpal, followed by curettage of the proximal phalanx and filling with structural autologous bone graft. The patient maintained a favorable postoperative clinical evolution, without local pain or range of motion limitation in his fingers. Radiologically, a progressive trabecular filling of the proximal phalanx of the fourth metacarpal was observed. At 17 months of follow-up, the patient is asymptomatic and shows no signs of relapse. The description of this case serves to increase the familiarity with this rare pathology, and aid its diagnosis and treatment.


Resumo Os tumores dos tecidos moles são raros em idade pediátrica. Descrito pela primeira vez 1969 como um mixoma da bainha nervosa, o neurotequeoma é uma lesão tumoral benigna com presumível origem na bainha nervosa. Ocorre maioritariamente em crianças do sexo feminino e apresenta-se como uma massa de crescimento lento, subcutânea, assintomática e sem alteração da pigmentação local. Localiza-se predominantemente na cabeça, no pescoço, e nas extremidades dos membros superiores. Os autores apresentam um caso clínico de um jovem de 16 anos do sexo masculino com massa tumoral com origem na bainha nervosa no 4º metacarpo esquerdo, intraóssea e recidivada após ressecção cirúrgica 2 anos antes do estudo. Foi feita ressecção marginal da massa tumoral localizada sobre a região distal do quarto metacarpo e curetagem da falange proximal e preenchimento com enxerto ósseo autólogo corticoesponjoso. O paciente apresentou uma evolução clínica pós-operatória favorável, sem queixas álgicas e sem limitações da mobilidade dos dedos da mão. Radiologicamente, foi observado preenchimento trabecular progressivo da falange proximal do quarto metacarpo. Aos 17 meses de seguimento, o paciente se encontra assintomático e não apresenta quaisquer sinais de recidiva. Com a descrição deste caso, os autores pretendem aumentar a familiaridade com essa rara patologia, seu diagnóstico e tratamento.

ABSTRACT

A 39-year-old male fisherman from Ceará State in Northeastern Brazil presented to the emergency room complaining of intense pain, edema, and bleeding in his left hand (Figure 1A-1B), He had a recent history of traumatism with hand perforation caused by the stinger of a gafftopsail catfish (Bagre marinus) (Figure 2A-2C). The injury occurred 4 hours prior when pulling his fishnet in the ocean. Right after the injury, the patient presented local pain and classified as eight in a visual analogue scale of pain. He denied systemic symptoms such as fever. On physical examination, he presented with two perforations separated by about 2 cm with slight bleeding (Figure 1A), local edema, and pain in his left hand (Figure 1B). Local cleansing of the lesion was performed. He was advised to apply warm compresses and used analgesics/anti-inflammatory drugs with the improvement of the inflammation. Systemic antibiotics were not necessary.


Um pescador de 39 anos, natural do Ceará, na região Nordeste do Brasil, deu entrada na emergência com queixa de dor intensa, edema e sangramento no dorso da mão esquerda (figura 1A-1B). Ele apresentava história recente de trauma na mão por ferrão de bagre branco (bagre marinus). A lesão ocorreu durante o ato de puxar a rede do oceano, quatro horas antes do atendimento. Logo após a lesão, apresentou dor intensa, nota 8 na escala visual analógica de dor. Ele negou sintomas sistêmicos, como febre. No exame físico, apresentava duas perfurações separadas por cerca de 2 cm com leve sangramento (figura 1A), edema e dor na mão esquerda (figura 1B). Foi realizada limpeza da lesão. Alem disso, foi orientado a aplicar compressas mornas e fazer uso de analgésicos /anti-inflamatórios para a melhora da inflamação. Antibióticos sistêmicos não foram necessários.
