ABSTRACT

Botulinum toxin type A (BTA) has analgesic effect independent of its action in muscle tone, inhibiting the release of neurotransmitters (substance P-glutamate) and neuropeptides of nociceptors. Objective: To characterize infiltration procedures with Botox® in patients with chronic pain refractory to treatment. Method: Observational-cross-retrospective study. Infiltrations with botox procedures performed in Hospital Clínico Mutual de Seguridad, between 01.01.2014 and 30.04.2015 were analyzed. Medical record data were extracted. Information analyzed with Excel2013® using Chi-square test (p <0.05). Results: 31 patients treated, 83.9 percent male. Average age 51 years (SD ± 11.9yo). Diagnostics causes of pain: post-traumatic pain and myofascial syndrome (25.8 percent); complex regional pain syndrome (16.1 percent) and partial hand amputation (12.9 percent). Predominant type of pain: neuropathic pain (64.5 percent). Common procedures: median nerve blockade (21.2 percent) and infiltration of lumbar back trigger points (15.4 percent). 77.4 percent reported good pain control, crisis decreased 74.2 percent and 71 percent decreases opioid use. Return work was effective in 64.5 percent of patients. 93.6 percent satisfactorily tolerated the procedure, 9.7 percent showed fewer adverse effects. The subgroup neuropathic pain had significantly worse results regarding mixed pain subgroup (p <0.05). Discussion: In this study, the use of BTA in chronic pain proved to be a safe and effective procedure for the management of chronic musculoskeletal pain...

ABSTRACT

The objective of this work was to study, through ultrasonographic evaluation, changes in testes and epididymides of clinically healthy, peripubertal and pubertal Santa Inês lambs raised in Brazil. Periodic e valuations of weight, biometric characteristics (scrotal circumference, width and length) and ultrasound examinatio ns of the testes and epididymides of 20 lambs were performed between 84 and 280 days old at intervals of 28 days. Scans were performed in the sagittal, transverse, frontal and oblique planes to evaluate the echotexture of the testicular parenchyma and mediastinum and the tail epididymis as well as the thickness and width of the mediastinum testis. The testicular parenchyma demonstrated a homogeneous echogenicity patter n ranging from low to moderate. The echogenicity of testicular parenchyma increased in direct proportion to animal age, being higher in pubertal lambs when compared to prepubertal at the same age. The mediastinum testis was observed in 100% of the evaluated animals, regardless of the scan plane used, and was classified as diffuse or moderately or highly echogenic. Echogenicity and the thickness of the mediastinum testis increased in direct proportion to animal age. The epididymal tail was presented in hypoechoic relation to the testicular parenchyma. Based on these results, it was concluded that ultrasound is useful tool for selection and morphophysiological evaluation of Santa Inês lambs on peripubertal and pubertal phases, when used in combination with other methods such as semen evaluation.

ABSTRACT

Objetivou-se descrever os achados ultrassonográficos nos testículos e epidídimos de carneiros jovens. Análises de desenvolvimento ponderal, mensurações das características biométricas testiculares e exames ultrassonográficos foram realizados dos 140 aos 280 dias de idade, a cada 28 dias. O parênquima testicular apresentou ecogenicidade homogênea (baixa a moderada) que aumentou com a idade. A ecogenicidade e a espessura do mediastino aumentaram com a idade, e a cauda do epidídimo apresentou aspecto hipoecoico em relação ao parênquima testicular. Foram observadas calcificações de grau leve nos testículos de cinco cordeiros. Conclui-se que o exame ultrassonográfico contribui para o monitoramento dos testículos e epidídimos de carneiros.


This study aimed to describe ultrasonographic findings in the testis and epididymis of young sheep. Evaluations of the development of weight, measurements of biometric characteristics of the tests and ultrasound examinations of the tests and epididymis were performed from 140 to 280 days of age, each 28 days. The testicular parenchyma showed homogeneous echogenicity (low to moderate) and increased with the age. The mediastinum echogenicity and thickness increased with age and the epididymis tail showed hypoechoic appearance in relation to the testicular parenchyma. Mild calcification was observed in the testis parenchyma of five lambs. In conclusion, ultrasonographic exams help to monitor testes and epididymis of young hair rams.

ABSTRACT

La periodontitis apical asintomática (PAa) es una patología infecciosa caracterizada por destrucción ósea perirradicular asociada a un proceso inflamatorio crónico y producción de mediadores inflamatorios, entre los cuales se encuentran las metaloproteinasas de matriz extracelular (MMPs). Entre éstas, las MMPs-13, -14, -2 y -9, son producidas por el tejido óseo y degradan sinérgicamente el colágeno tipo I, principal componente de los tejidos periodontales, y gelatina, producto de la degradación y desnaturación del colágeno. El objetivo de este estudio fue determinar el patrón de expresión de las MMPs-2, -9, -13 y -14 en granulomas periapicales (GPAs), quistes radiculares inflamatorios (QRIs) y ligamento periodontal sano (LS). Materiales y Métodos: Se seleccionaron 12 pacientes con diagnóstico clínico de PAa e indicación de exodoncia a partir de los cuales se obtuvieron biopsias de lesiones periapicales (LPAs). Como controles, se seleccionaron 7 individuos con indicación de exodoncia de premolares por ortodoncia, obteniéndose biopsias de LS. Se efectuó el diagnóstico anátomo-patológico de los especímenes y se caracterizó la expresión de las MMPs en estudio mediante inmunohistoquímica. Resultados: Las MMPs en estudio sólo se detectaron en GPAs y QRIs, y se inmunolocalizaron principalmente en el infiltrado inflamatorio de éstos. Adicionalmente, la MMP-2 se identificó en fibroblastos del tejido conectivo. Conclusiones: MMPs-2, -9, -13 y -14 se expresan predominantemente en el infiltrado inflamatorio de las LPAs y no en LS, y por tanto se sugiere la participación de estos mediadores en la patogénesis de la PAa.


Asymptomatic apical periodontitis (aAP) is an infectious disease characterized by perirradicular bone destruction associated with chronic inflammation and release of inflammatory mediators, such as matrix metalloproteinases (MMPs). MMPs-13, -14 and -2, -9 are bone-expressed enzymes that can synergistically degrade collagen I, the main component of periodontal extracellular matrix, and gelatin, the product of degradation and denaturation of collagen. The aim of this study was to characterize the expression pattern of MMPs-2, -9, -13, and -14 in periapical granulomas (PGs), radicular cysts (RCs) and healthy periodontal ligament (PDL). Materials and Methods: Individuals with clinical diagnosis of aAP and indication of extraction were selected (N=12), and biopsies of periapical lesions (PLs) were obtained. For controls, 7 subjects with indication of premolar extraction for orthodontic reasons were selected, and PDL biopsies were obtained. Samples were diagnosed by anatomopathological examination and immunohistochemical staining was carried out to characterize MMPs expression. Results: MMPs-2, -9, -13 and -14 detection was limited to PLs and were localized mainly to inflammatory infiltrate on both, PGs and RCs. Additionally, MMP-2 was immunolocalized to fibroblasts from the connective tissue. Conclusions: Whereas MMPs-2, -9, -13 and -14 were not detected in healthy periodontal ligament, they were highly expressed on inflammatory infiltrate from PGs and RCs, suggesting a role of these mediators in aAP pathogenesis.

ABSTRACT

Infantile Hemangiomas (IH) are common vascular tumors in children. Only 10-15 percent) should be treated by any vital, functional or aesthetic complications. Oral corticosteroids are the treatment of choice. However, in the last two years an excellent response to treatment of hemangiomas with oral Propranolol has been reported. Objective: evaluate this new therapy in a limited number of chilean patients with IH with an indication of systemic treatment and present this experience. Patients and Methods: We present 30 cases of IH treated at our institution with oral Propranolol, using a dose of 2 mg/kg/day divided in 2 daily doses. Results: 11 percent of patients were female, 40 percent hemangiomas had segmental distribution, 90 percent were solitary, 61 percent were located in the head and neck and 23 percent were ulcerated. The treatment started at an average of 119 days of life and lasted for an average of 7 months. In all our patients the use of Propranolol accelerated the onset of involution of the hemangiomas and decreased color, brightness and growth too. 43 percent of the patients had irritability and sleep disorders. No significant adverse effects were reported in any of our patients. Conclusión: Propranolol treatment was highly effective and safe in our series of patients and we propose, taking into account published reports based on this data, it should become the treatment of choice for IH.


Los Hemangiomas de la Infancia (HI) son tumores vasculares frecuentes en la edad pediátrica. Sólo un 10-15 por cientoo debe ser tratado por eventuales consecuencias vitales, funcionales o estéticas. Los corticoides orales son el tratamiento de elección actual. Sin embargo, en los últimos 2 años se ha reportado la excelente respuesta de los hemangiomas al tratamiento con Propranolol oral. Objetivo: Evaluar esta nueva terapéutica en un número limitado de pacientes Chilenos con hemangiomas de la infancia con indicación de tratamiento sistémico y presentar esta experiencia. Pacientes y Método: Presentamos 30 casos de HI tratados en nuestra institución con Propranolol oral, usando una dosis de 2 mg/kg/día en 2 tomas diarias. Resultados: Un 77 por ciento de los pacientes eran de sexo femenino. El 40 por ciento de los hemangiomas eran segmentarios, 90 por ciento eran únicos, 67 por ciento estaban ubicados en cabeza y cuello y 23 por ciento estaban ulcerados. El tratamiento se inició en promedio a los 119 días de vida y duró en promedio 7 meses. En la totalidad de nuestros pacientes el uso de Propranolol aceleró el inicio de la involución del hemangioma y disminuyó el color, brillo y crecimiento. El 43 por ciento de los pacientes presentó irritabilidad y trastornos del sueño. No se presentaron efectos adversos importantes en ninguno de nuestros pacientes. Conclusión: El tratamiento con Propranolol fue altamente efectivo y seguro en nuestra serie de pacientes y proponemos, tomando en cuenta los reportes publicados al respecto, que debiera ser el tratamiento de elección para los hemangiomas de la infancia.

ABSTRACT

Congenital Cutis Marmorata Telangiectasia (CCMT) is a skin vascular malformation of low flow compromi-sing venous and capillary vessels. Of unknown origin, it shows in an estimated 1/3 000 births. In over 90 percent of cases it can be seen since birth, although it can appear on the first few days after. Clinical manisfestation includes poorly defined reticular erythematopurpureal maculae, frequently associated to ßreas of segmental, asymetric skin atrophy, most often seen in the lower extremitie. The diagnosis is mostly clinical, important to make as it is associated in 30 percent) of cases to other congenital abnormalities. No specific treatment is required, with spontaneous resolution. Prognosis is good, depending on the associated malformations. Four patients are described in this paper, as a reminder of the clinical entity.


El Cutis Marmorata Telangiectático Congénito (CMTC) es un tipo de malformación vascular cutánea de bajo flujo que compromete vasos capilares y venosos. Su causa es desconocida y tiene una incidencia estimada de 1/3 000 recién nacidos. En más del 90 por ciento> de los casos se presenta desde el nacimiento. Sin embargo, también puede aparecer en los primeros días de vida. Clínicamente se observan máculas eritematovioláceas, de aspecto reticulado, de bordes mal definidos, asociado frecuentemente a zonas de atrofia cutánea, de distribución segmentaria, asimétricas. Se ubican de preferencia en las extremidades, siendo las inferiores las más afectadas. El diagnóstico es fundamentalmente clínico y su importancia radica en que aproximadamente el 30 por ciento> de los casos se asocia a otras anomalías congénitas, la mayoría de carácter leve. No tiene un tratamiento específico, ya que evoluciona en poco tiempo a la resolución en forma espontánea. El pronóstico es generalmente bueno, aunque depende de las anomalías asociadas. En este artículo se presentan cuatro pacientes cuya historia clínica es compatible con este diagnóstico, para dar a conocer esta entidad clínica a los pediatras.

ABSTRACT

Introducción: Las Reacciones de Hipersensibilidad Medicomentosa (RHM) son un motivo de consulta muy común en Dermatología. Con el objetivo de implementar la farmacovigilancia dentro de la Sociedad Chilena de Dermatología (SOCHIDERM) se creó un Protocolo paro la notificación de RHM de tipo muco-cutáneo. Objetivo: Validar una propuesta de Protocolo de Farmacovigilancia de RHM de tipo mucocutáneo de la SOCHIDERM paro el uso de dermatólogos y médicos de nuestro país. Resultados: En nuestro estudio, la frecuencia de RHM fue 0,3% -0,5% del total de consultas ambulatorias y 5,2% 17,2% de las interconsultas a Dermatología. Los patrones más frecuentes fueron el urticarial, morbiliforme y la reacción medicamentosa fija. Los fármacos imputados con mayor frecuencia fueron los analgésicos/antiinflamatorios, los fármacos con acción en el sistema nervioso central, los antibióticos y los antihipertensivos. Discusión: Es importante tener un Protocolo de Farmacovigilancia. Esto nos permitirá obtener datos a nivel nacional. El desafío a corto plazo paro farmacovigilancia en SOCHIDERM es lograr notificar las RHM de tipo muco-cutáneo graves o con compromiso vital, que sean atendidas por dermatólogos en nuestro país, a través del Protocolo de Farmacovigilancia SOCHIDERM.


Introduction: Drug Hypersensitivity Reactions (DHR) are a common cause of consultation in dermatology. In order to implement fharmacovigilance in the Chilean Society of Dermatology (SOCHIDERM), we created a protocol for the notification of mucocutaneous DHR. Objective: To validate a SOCHIDERM mucocutaneous DHR pharmacovigilance protocol for dermatologists and physicians in our country. Results: In our study. DHR accounted for 0.3-0.5 % of all outpatient consultations, and 5,2-17,2% of interconsultations in dermatology. The most frequent patterns were urticarial, morbilliform and fixed drug reaction. The drugs most frequently involved were analgesics/anti-inflammatory drugs with action in the central nervous system, antibiotics and antihypertensives. Discussion: It is important to have a Pharmacovigilance Protocol since it will allow to obtain nationwide data. The short-term challenge for the SOCHIDERM pharmacovigilance is to notify serious or life-threatening mucocutaneous DHR that have been seen by dermatologists in our country, through this Protocol.

ABSTRACT

Introducción: La obesidad mórbida es una patología de creciente consulta en nuestro medio a la cual los servicios de salud público no están ajenos. En la actualidad la cirugía ha demostrado ser el tratamiento más eficaz a largo plazo. Objetivos: Informar los resultados obtenidos en el tratamiento de obesos mórbidos sometidos a cirugía abierta en un servicio hospitalario público regional. Material y método: Se analiza en forma prospectiva los primeros 100 pacientes sometidos a cirugía bariátrica en el Hospital de Coquimbo entre Septiembre de 1998 y Diciembre de 2005. Se usaron 3 técnicas en forma consecutiva. En todas ellas se efectuó el bypass gástrico empleando anastomosis en Y de Roux con asa larga de 160 cm. Para los análisis estadísticos se emplearon los test de ANOVA y Student. Resultados: El 83 por ciento de los operados fueron mujeres. El IMC preoperatorio promedio fue de 46 kg/m², siendo un 29 por ciento superobesos (IMC>50). La estadía postoperatoria promedio fue de 7,6 días. Complicaciones postoperatorias precoces hubo en el 5 por ciento. No se registró mortalidad operatoria en esta serie. El promedio de reducción de exceso de peso fue de 60 por ciento a los 6 meses, 72 por ciento al año y 66 por ciento a los 3 años. Conclusiones: Los resultados obtenidos en un hospital público regional en relación a la cirugía bariátrica son absolutamente comparables a estudios nacionales e internacionales, tanto en la reducción de peso como en la morbimortalidad.


Background: Surgery is the most effective treatment in the long run, for morbid obesity. Aim: To report the results of open bariatric surgery for morbid obesity in a regional public hospital. Material and methods: Prospective study of the first 100 patients aged 14 to 62 years (84 percent women) undergoing bariatric surgery in Coquimbo hospital between September 1998 and December 2005. A Horizontal Gastroplasty without gastric resection was done in 13 patients, a 6/7 Gastrectomy in 58 and a 9/10 Gastrectomy in 29. A gastric bypass with Roux-en-Y anastomosis with a 160 cm long loop, was always performed. Results: Preoperative body mass index (BMI) was 46 kg/m². Twenty nine percent had a BMI over 50 kg/m². The average postoperative hospital stay was 7.6 days. Five percent had early complications. No patients died. The average excess weight loss at 6 months, one and three years after surgery was 60, 72 and 66 percent respectively. Patients subjected to a gastric resection had a higher percentage of excess weight loss than gastroplasty after 1 year (p <0.01). After 3 years, the greatest excess weight loss was seen in patients with a BMI below 50 kg/m² subjected to Gastrectomy. The smaller excess weight loss was observed in patients with a BMI over 50 kg/m² subjected to Gastroplasty. After 6 months and 1 year, patients undergoing larger Gastrectomies (9/10) had a significantly greater percentage weight loss than those subjected to smaller resections (6/7). Conclusions: These results obtained in a public hospital surgery service with bariatric procedures are comparable with those of national and international studies, both in terms of weight loss and complications.

ABSTRACT

La dinamica respiratoria se efectua en el post-operatorio de cirugia abdominal, aun en sujetos sanos con funcion pulmonar indemne, individuos con antecedentes de riesgo pueden hacer complicaciones como: atelectasia, neumonia, falla respiratoria aguda, etc. Tradicionalmente como medida preventiva se recomienda fisioterapia respiratoria despues de la cirugia. Con el objeto de valorar la eficacia de esta, se estudiaron tres grupos de 10 pacientes, cada uno un grupo control, uno que realizo insuflacion de globos y el tercero fisioterapia con sello de agua. Se valoro gasometria y espirometria. Los resultados encontrados nos indicarian que la fisioterapia no mejora la ventilacion, ya que constituye un proceso activo, dependiente de la voluntad del paciente, el mismo que disminuye por el dolor y otros factores. En el grupo que trabajo con sello de agua, se encontro mejores parametros en el intercambio gaseoso, probablemente debido a la presion positiva en la via aerea que genera este metodo, lo que evitaria el colapso de los bronquioalveolos.

ABSTRACT

The blood helper/suppressor ratio was measured in 38 patients with biopsy-proved sarcoidosis. There was no relationship between this peripheral helper/suppressor ratio and the activity of the granulomatous process. This test needs further evaluation before its routine use in assessing activity in sarcoidosis.
