RESUMO

Abstract Introduction: Muscular transposition procedures are used when there is no ocular rotation in a particular direction due to alterations of the extraocular muscles such as paralysis, agenesis or congenital anomalies. The objective of this study is to characterize the patients treated with this procedure and determine the percentage of correction of the deviation angle obtained after surgery in the Pediatric Ophthalmology, Strabismus and Neuro-ophthalmology Unit. "Dra. Ana María Illescas Putzeys", Hospital de ojos y oídos "Dr. Rodolfo Robles V. Methods: A retrospective, descriptive, observational study was conducted with review of records of patients operated on muscle transposition during the years 1999 to 2016. Results: Twenty-three rectus muscle transposition procedures were performed. Thirteen were male (56.5%). The mean age was 42 years. In our series, an average correction of 42 PD (82%) was obtained regardless of the type of paralysis or the surgical procedure performed. Conclusion: In selected cases of paralytic strabismus, the main approach may be only muscle transposition with augmentation (posterior intermuscular fixation suture), with good results, similar to those obtained with muscle transposition using adjuvants such as botulinum toxin treatment.


Resumo Introdução: Os procedimentos de transposição muscular são utilizados quando não há rotação ocular em nenhuma direção determinada devido a alterações dos músculos extraoculares, como paralisia, agenesia ou anomalias congênitas. O objetivo deste estudo é caracterizar os pacientes tratados com este procedimento e determinar a porcentagem de correção do ângulo de desvio obtida após a cirurgia na Unidade Pediátrica de Oftalmologia, Estrabismo e Neuro-Oftalmologia. "Dra. Ana María Illescas Putzeys", Hospital de ojos y oídos "Dr. Rodolfo Robles V. Métodos: Foi realizado um estudo retrospectivo, descritivo, observacional, com revisão dos registros de pacientes operados para transposição muscular nos anos de 1999 a 2016. Resultados: Foram realizados vinte e três procedimentos de transposição do músculo reto. Treze pacientes eram homens (56,5%). A idade média foi de 42 anos. Em nossa série, foi obtida uma correção média de 42 PD (82%), independente do tipo de paralisia ou do procedimento cirúrgico realizado. Conclusão: Em casos selecionados de estrabismo paralítico, a principal abordagem pode ser apenas a transposição muscular com aumento (sutura de fixação intermuscular posterior), com bons resultados semelhantes aos obtidos com a transposição muscular com a utilização de adjuvantes como o tratamento com toxina botulínica.

RESUMO

CASOS CLÍNICOS: Describimos los casos de dos pacientes de sexo femenino con síndrome de Straatsma y tratamiento satisfactorio de ambliopía. DISCUSIÓN: La anisometropía y la mielinización de fibras nerviosas de la retina (MFNR) fue diferente en cada paciente; pero las dos alcanzaron agudeza visual con corrección de 0,20 (logMAR) en ambos ojos posterior al tratamiento de ambliopía con parche ocular. El pronóstico visual de ambliopía asociada a MFNR y anisometropía es peor que en ambliopía anisometrópica sin MFNR, siendo la primera refractaria a la terapia oclusiva. La rehabilitación visual debe intentarse a pesar de encerrar un mal pronóstico. Nuestros casos fueron tratados exitosamente con parche ocular


CLINICAL CASES: The cases are presented on 2 female patients with Straatsma syndrome, with satisfactory treatment of amblyopia. DISCUSSION: The level of anisometropia and myelination of retinal nerve fibres were different in these two patients. However, both achieved 0.20 (logMAR) visual acuity with correction in both eyes following amblyopia treatment with ocular patching. Visual prognosis of amblyopia associated with myelination of retinal nerve fibres and anisometropia is poorer than anisometropic amblyopia without myelination. It is well known that the former is refractory to occlusive therapy. Despite having a poor prognosis, visual rehabilitation should be attempted. The two cases presented were successfully treated with eye-patching

RESUMO

Introducción. La obstrucción congénita de la vía lagrimal es una patología común, de poca morbilidad, pero no exenta de complicaciones sin el diagnóstico y manejo correcto. Población y métodos. Estudio retrospectivo de 2005 a 2015 en pacientes que fueron sometidos a un procedimiento de sondaje. Se identificó edad al momento del procedimiento, género, lateralidad y presencia o ausencia de éxito con el procedimiento. Resultados. Se analizaron 137 ojos. La mediana de edad fue de 17 meses y la tasa de éxito total fue del 85,4%. Conclusión. La obstrucción congénita de la vía lagrimal con adecuado manejo conservador inicial tiene alta tasa de resolución espontánea y, en pacientes mayores de 12 meses, el sondaje tiene una alta tasa de éxito.

RESUMO

BACKGROUND: The pterional approach (PA), together with its variants, is still one of the most common methods used by surgeons to reach the anterior and middle cranial base. A highly important technical detail during a PA is the preservation of the frontotemporal branch of the facial nerve, which can be achieved through an interfascial dissection. OBJECTIVE: To describe the anatomy of the interfascial vein (IFV), highlighting its recognition as a significant anatomic reference to perform an interfascial dissection (IFD). METHODS: Eight adult cadaveric heads, fixed with formaldehyde and injected with colored silicone, were studied. In 6 heads, an IFD was performed, simulating a PA. In the 2 remaining heads, the IFV was dissected. In addition, an IFD was performed in 10 patients, studying the IFV anatomy. RESULTS: In the 6 cadaveric heads in which the PA with an IFD was performed, and in the 10 patients who underwent a PA with an IFD, the IFV was found. If the interfascial space is divided into thirds, in all cases, the IFV was located within the middle third of the interfascial fat pad. On the 2 cadaveric heads in which the IFV was anatomically dissected, the IFV was also located within the middle third of the interfascial space. CONCLUSION: Recognizing the IFV in the interfascial space is of great help as an anatomic landmark to confirm that one is actually between both layers of the superficial temporal fascia.

RESUMO

Objetivo: La retinopatía del prematuro es una alteración proliferativa de los vasos sanguíneos de la retina. En Guatemala son pocos los datos que se tienen de la enfermedad; por lo que se realizó un estudio para caracterizar y determinar la prevalencia de retinopatía del prematuro en el Hospital Nacional de Chimaltenango. Material y métodos: Se realizó un estudio prospectivo, descriptivo, observacional; durante los meses de octubre de 2015 a septiembre de 2016 en el Hospital Nacional de Chimaltenango. Se examinaron 76 neonatos prematuros. Se incluyeron pacientes con peso al nacer 2000 gramos y/o edad gestacional 37 semanas. Resultados: 17 (22,36%) pacientes con retinopatía del prematuro, de los cuales 3 (3,95%) recibieron tratamiento. La edad gestacional promedio de los pacientes que desarrollaron enfermedad plus fue de 35,33 semanas (DS 1,15); con un peso promedio de 1861,67 gramos (DS 734,76). De los 76 neonatos evaluados 48,00% estaban fuera de lo recomendado para el tamizaje en Latinoamérica y de éstos el 18,00% presentaron RP, incluyendo uno de los casos que ameritó tratamiento. Conclusiones: La prevalencia es similar a otros estudios reportados en países en vías de desarrollo. Sin embargo, este estudio mostró la importancia de contar con datos propios de cada Unidad de Cuidados Intensivos Neonatales; ya que se encontraron pacientes fuera de los parámetros recomendados para el tamizaje en Latinoamérica.(AU)

RESUMO

OBJECTIVE: The aim of this study is to describe the results of 16 patients with posterior fossa hemangioblastoma, treated with microsurgical techniques. METHOD: Between June 2005 and December 2015, 16 patients with posterior fossa hemangioblastoma were operated on, underwent microsurgical resection. The sex, age, imaging findings, symptoms, and postoperative results were analyzed. RESULTS: Eleven patients were men and 5 were women. The average age of the patients was 44 years. The most common form was cystic with nodule (57%); in 31% of the cases the lesion was purely solid. One case (6%) showed a lesion purely cystic, and one case was solid-cystic (6%). The major presenting symptoms were headache and cerebellar syndrome (43%); in 25% of the cases the patients suffered intracranial hypertension syndrome. The total resection was achieved in all the cases; in one patient an embolization was performed before surgery. Regarding postoperative complications: two patients developed ataxia (improved after three months), 1 patient presented a CSF leak (improve with an external spinal drainage). In addition, one patient died because postoperative complications. CONCLUSION: The major features in patients with posterior fossa hemangioblastoma are a cystic with nodule form, presenting symptoms of headache and cerebellar syndrome. The total resection is possible, with a low morbi-mortality rate.

RESUMO

Objetivo: El propósito del presente trabajo es presentar los resultados de 16 pacientes con diagnóstico de hemangioblastoma de fosa posterior (HBFP), operados con técnicas microquirúrgicas. Método: Desde Junio de 2005 a Diciembre de 2015, 16 pacientes con diagnóstico de HBFP fueron intervenidos quirúrgicamente. Se evaluó: sexo, edad, tipo de lesión (quística con nódulo, quística sin nódulo, sólida y sólida-quística), sintomatología y resultados postoperatorios. Resultados: De los 16 pacientes intervenidos, 11 fueron varones y 5 mujeres. La edad promedio fue de 44 años. La forma más frecuente fue quística con nódulo (57%), seguida por forma sólida (31%). Un solo caso presentó la forma quística sin nódulo (6%), y uno solo la forma sólido-quística (6%). La sintomatología más frecuente fue cefalea acompañada de síndrome cerebeloso (43%), seguido de síndrome de hipertensión endocraneana (25%). En todos los casos la resección fue completa, siendo necesario en un caso una embolización previa. Como complicaciones postoperatorias, 2 pacientes presentaron ataxia (mejoró al cabo de 3 meses), y 1 paciente presentó una fístula de LCR (se solucionó con un drenaje espinal externo). Se registró un óbito por complicaciones postoperatorias. Conclusión: Lo más frecuente de ver en pacientes con HBFP es la forma quística con nódulo, siendo su sintomatología predominante la cefalea acompañada de síndrome cerebeloso. La resección quirúrgica completa es posible, con una baja tasa de morbimortalidad.

RESUMO

UNLABELLED: We describe a case of a 30-year-old woman who suffered a traumatic injury of the right brachial plexus, developing severe complex regional pain syndrome type II (CRPS-II). After clinical treatment failure, spinal cord stimulation (SCS) was indicated with initial positive pain control. However, after 2 years her pain progressively returned to almost baseline intensity before SCS. Additional motor cortex electrode implant was then proposed as a rescue therapy and connected to the same pulse generator. This method allowed simultaneous stimulation of the motor cortex and SCS in cycling mode with independent stimulation parameters in each site. At 2 years follow-up, the patient reported sustained improvement in pain with dual stimulation, reduction of painful crises, and improvement in quality of life. The encouraging results in this case suggests that this can be an option as add-on therapy over SCS as a possible rescue therapy in the management of CRPS-II. However, comparative studies must be performed in order to determine the effectiveness of this therapy. KEY WORDS: Chronic neuropathic pain, Complex regional pain syndrome Type II, brachial plexus injury, motor cortex stimulation, spinal cord stimulation.

RESUMO

PURPOSE: Conjunctival tissue tumors have a varied presentation, and few series studies on pediatric patients have been published. The objective of this paper is to report the histopathologic diagnoses (spanning over 1988-2013) of conjunctival tumors in children younger than 14 years. METHODS: We conducted a retrospective, descriptive, and observational study by reviewing the database of all children in whom a conjunctival tumor was surgically removed at Hospital de Ojos y Oídos "Dr. Rodolfo Robles V.," Benemérito Comité Pro Ciegos y Sordos de Guatemala. The data pertaining to gender, age, and histopathologic diagnosis of all cases was collected. The same ocular pathologist made all diagnoses. RESULTS: One hundred sixty-five cases were found, with a mean age of 7.88 years, being 91 (55.15%) male subjects. Melanocytic lesions were the most common tumors found (30.91% of cases), with only one case (0.60%) being malignant. CONCLUSIONS: Melanocytic lesions were the most common tumors found, and of all the cases, only one was malignant; this was in a patient with xeroderma pigmentosum. These findings are consistent with those reported in other studies regarding the frequencies of the histopathology of conjunctival tumors in the pediatric population.

RESUMO Objetivo: Tumores do tecido conjuntival tem uma apresentação variada. Poucas séries de pacientes pediátricos foram publicadas. O objetivo deste trabalho é apresentar os diagnósticos histopatológicos de tumores conjuntivais em crianças com menos de 14 anos de idade, obtidas durante um período de 25 anos. Métodos: Estudo retrospectivo, descritivo e observacional foi realizado. Nós revisamos o banco de dados de todas as crianças em quem um tumor conjuntival foi removido cirurgicamente no Hospital de Ojos y oidos "Dr. Rodolfo Robles V.," Benemérito Comité Pro Ciegos y Sordos de Guatemala. Sexo, idade e diagnóstico histopatológico de todos os casos foram compilados. O mesmo patologista ocular fez todos os diagnósticos. Resultados: Cento e sessenta e cinco casos foram encontrados, com média de 7,88 anos, sendo 91 (55,15%) do sexo masculino. Lesões melanocíticas foram as mais frequentes (30,91% dos casos). Apenas um caso (0,60%) era maligno. Conclusões: Lesões melanocíticas foram as mais frequentes. Do total, apenas uma lesão era maligna, o que correspondeu a um paciente com xeroderma pigmentoso. Estes resultados são consistentes com o relatado em outros estudos quanto à frequência de diagnóstico histopatológico de tumores da conjuntiva na população pediátrica.

RESUMO

El trauma ocular pediátrico es frecuente y es la principal causa de ceguera unilateral no congénita. La información en países en vías de desarrollo es escasa. El objetivo de esta serie de casos es describir las características clínicas y epidemiológicas del trauma ocular en niños menores de 14 años que consultaron al Hospital Dr. Rodolfo Robles Val verde en la Ciudad de Guatemala durante el año 2010. Se incluyeron 119 pacientes en el estudio. El género masculino en edad escolar (7-9 años) fue el más comprometido. El trauma más común fue el de globo cerrado. Los objetos más frecuentes causantes de la lesión fueron madera, juguetes y químicos. La vivienda fue el lugar donde más ocurrió el trauma. Se intervinieron 21 pacientes. Son necesarios programas de educación y prevención.


Pediatric ocular trauma is common and the leading cause of non congenital unilateral blindness. The information in developing countries is scarce. The objective of this case series is to describe clinical and epidemiological characteristics of ocular trauma in children under 14 years of age who visited Hospital Dr. Rodolfo Robles Valverde in Guatemala City in 2010. In this study 119 patients were included. School-aged (7-9 years) male gender was the most affected. Closed globe injury was the commonest. The most frequent objects causing the lesions were: wooden objects, toys and chemicals. Trauma occurred most frequently at home. Twenty one of the patients were surgically intervened. Education and prevention programs for pediatric ocular trauma are necessary.

Introducción: El abordaje suboccipital constituye una de las vías de acceso más frecuentes a la fosa posterior. Objetivo: La finalidad del presente estudio es definir un reparo anatómico reproducible en la superficie suboccipital del cerebelo que permita ayudar a localizar el núcleo dentado (ND) del mismo. Material y Métodos: Quince cerebelos de adulto fueron estudiados, previa fijación con formol y congelación. Se realizaron cortes axiales y sagitales, con medición de las relaciones entre la fisura horizontal (FH) y el ND. Resultados: La proyección en profundidad de la FH permitió identificar el núcleo dentado en casi todos ellos. Conclusión: La identificación del ND en la cirugía a partir de la FH puede ser considerada un método rápido y confiable. Su utilización pre y perioperatoria podría disminuir las complicaciones derivadas de la lesión de dicho núcleo cerebeloso.


Introduction: The suboccipital approach is one of the most common surgical routes to the posterior fossa.Purpose: The aim of this study was to define a reproductible anatomic landmark in the suboccipital surface of the cerebellum, allowing to localize the dentate nucleus (DN).Material and methods: Fifteen cadaveric specimens (adult brains) were studied, previously fixed with formaldehyde and frozen. Sagittal and axial cuts were performed in the specimens, measuring the relationships between the horizontal fissure (HF) of the cerebellum and the DN.Results: The projection in depth of the HF allowed to identify the DN in almost all of them.Conclusion: The identification during surgery of the DN using the HF maybe a safe and quick method and its usage pre and intraoperatively can lower complications related to lesions of the DN.
