Resultado de tratamiento quirúrgico de la luxación recidivante de rótula mediante la técnica de Campbell / Result of surgical treatment of recurrent patella dislocation using the Campbell technique

Resumen: Introducción: La luxación recidivante de rótula es una condición en la cual no se mantiene la congruencia de la superficie de la rótula en su desplazamiento sobre el surco intercondíleo del fémur en los movimientos de flexoextensión de la rodilla. Los objetivos del trabajo son: mostrar la distribución de pacientes con luxación recidivante de rótula según diferentes variables sociodemográficas y evaluar los resultados con el uso de la técnica de Campbell. Material y métodos: Se llevó a cabo un estudio observacional en pacientes con luxación recidivante de rótula, en el período de Diciembre de 2017 a Diciembre de 2019. La recolección de datos se realizó con la revisión de las historias clínicas. La muestra fue de 19 pacientes, para la evaluación de la técnica quirúrgica se utilizó el sistema propuesto por los autores. El procesamiento de la información incluyó el cálculo de medidas de resumen para variables cualitativas, frecuencias absolutas y porcentajes. Resultados: El sexo femenino y el grupo de edad de 15 a 30 años fueron los más frecuentes, la cicatrización fue mala en dos pacientes. Se obtuvieron buenos resultados en 84.3% de los pacientes operados. Conclusiones: Predominó el sexo femenino y el grupo de 15 a 30 años, la cicatrización fue mala en dos pacientes. Se obtuvieron buenos resultados en los pacientes operados. A pesar de que la mayoría de los autores recomiendan la reparación del ligamento patelofemoral medial como técnica de elección o la técnica de Insall, la técnica de Campbell arroja buenos resultados cuando se aplica a luxación recidivante de rótula que necesita realineación proximal del mecanismo extensor.

Abstract: Introduction: the recurrent dislocation of the patella is a condition in which the congruence of the surface of the patella is not maintained in its displacement on the intercondyleal groove of the femur in the flexo-extension movements of the knee. The objectives of the study are: to show the distribution of patients with recurrent dislocation of patella according to different socio-demographic variables and to evaluate the results with the use of campbell's technique. Material and methods: An observational study was conducted in patients with recurrent patella dislocation in the period from December 2017 December 2019. Data collection was carried out with the review of medical records. The sample was 19 patients, the evaluation of the surgical technique was used the system proposed by the authors. Information processing included the calculation of summary measures for qualitative variables, absolute frequencies and percentages. Results: The female sex and the age group of 15 to 30 years were the most frequent, healing was poor in two patients, good results were obtained in 84.3% of the operated patients. Conclusions: Predominance of the female sex and the group of 15 to 30 years, the healing was bad in two patients, good results were obtained in the operated patients. Although most authors recommend medial patello-femoral ligament repair as a technique of choice or the Insall technique, Campbell's technique yields good results when applied to recurrent patella dislocation that need proximal realignment of the extensor mechanism.

Serum YKL-40 levels in patients with multiple sclerosis / Níveis séricos de YKL-40 em pacientes com esclerose múltipla

ABSTRACT Background: Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system. The YKL-40 protein, which is secreted from various cells that contribute to inflammation and infection, plays a role in immune regulation. Objective: This study investigated the serum YKL-40 levels of patients with clinically isolated syndrome (CIS) and MS. Methods: The participants was divided into three groups: 1) patients with CIS (n = 20); 2) patients with relapsing-remitting MS (RRMS; n = 39); and 3) healthy individuals (n = 35). The YKL-40 levels in serum samples obtained from the participants were measured using enzyme-linked immunoassays. Results: The median serum YKL-40 level was 20.2 ng/mL (range 9.8-75.9 ng/mL) in the patients with CIS, 22.7 ng/mL (range 13.4-57.9 ng/mL) in the patients with RRMS and 11.0 ng/mL (range 10.0-17.3 ng/mL) in the control group (p < 0.001). The serum YKL-40 levels in the patients with RRMS were correlated with the patients' expanded disability status scale scores and ages (p < 0.05). No relationships were determined between the serum YKL-40 levels and the other variables (p > 0.05). The serum YKL-40 levels were higher in the CIS group than in the MS group. These findings show that the serum YKL-40 levels were high even at the beginning of the disease. The serum YKL-40 levels were also not involved in the progression to clinically definite MS. Conclusions: The findings from this study suggested that YKL-40 may be a useful marker for the inflammatory process of MS.

RESUMO Contexto: A Esclerose Múltipla (EM) é uma doença inflamatória crônica que afeta o sistema nervoso central. A proteína UKL-40, secretada de várias células que participam de processos inflamatórios e infecciosos, desempenha um importante papel na regulação imunológica. Objetivo: Este estudo investigou níveis séricos de YKL-40 em pacientes com Síndrome Clinicamente Isolada (SCI) e EM. Métodos: Os participantes foram divididos em três grupos: 1) pacientes com SCI (n = 20); 2) pacientes com EM recorrente-remitente (EMRR; n = 39); e 3) indivíduos saudáveis (n = 35). Os níveis de YKL-40 em amostras séricas obtidas dos participantes foram medidos usando-se imunoensaios ligados a enzimas. Resultados: O nível sérico médio de YKL-40 foi 20.2 ng/mL (range 9.8-75.9 ng/mL) em pacientes com CIS, 22.7 ng/mL (intervalo entre 13.4-57.9 ng/mL) em pacientes com EMRR e 11.0 ng/mL (intervalo entre 10.0-17.3 ng/mL) no grupo controle (p < 0.001). Os níveis séricos de YKL-40 em pacientes com EMRR estavam correlacionados às pontuações e idades dos pacientes na EDSS (p < 0.05). Não foram determinadas relações entre os níveis séricos de YKL-40 e outras variáveis (p > 0.05). Os níveis séricos de YKL-40 no grupo SCI estavam mais elevados do que no grupo EM. Estes resultados demonstram que os níveis séricos de YKL-40 estavam mais elevados até mesmo no início da doença. Os níveis séricos de YKL-40 também não estavam associados à progressão da EM clinicamente definida. Conclusões: A partir deste estudo, os resultados sugeriram que a proteína YKL-40 pode ser um indicador útil no processo inflamatório da EM.

Tratamento cirúrgico de luxação recidivante da mandíbula: relato de caso / Surgical treatment of recurrent mandible luxation: case report

Introdução: A articulação temporomandibular (ATM) é uma estrutura especializada e excepcional, relacionada com funções estomatognáticas e propensa à disfunções associadas ao sistema maxilo-mandibular. Dentre essas alterações, a luxação é uma entidade patológica importante. Possui patogênese multifatorial e pode se manifestar de modo recidivante. Diversos tratamentos são propostos, dentre eles, a criação de anteparos aloplásticos. Paciente do sexo feminino, 22 anos com história de luxação mandibular recidivante com sintomatologia congruente ao quadro. Realizou-se tratamento cirúrgico com instalação de miniplacas de titânio do sistema 2.0 mm em forma de duplo T com curvatura de aproximadamente 90°, na região de eminencia articular. Após 1 ano e 6 meses, a paciente segue assintomática, sem lesões nervosas e sem luxações. A luxação da ATM é um quadro clínico angustiante, sendo a segunda luxação mais frequente e incidente em mulheres. Caracteriza-se por: incapacidade de fechar a boca, depressão cutânea pré-auricular, ptialismo e musculatura mastigatória tensa. A paciente apresentava severas luxações recidivantes, juntamente com ansiedade e angústia social. A utilização de placas evitou a hiperexcussão e remissão do quadro. É um procedimento menos agressivo e reversível. A técnica utilizada demonstrou bom prognóstico e, dentre as opções cirúrgicas, é uma técnica mais conservadora... (AU)

Introduction: TMJ dislocation is a multifactorial joint pathology that occurs when the mandibular condyle exceeds the articular eminence and cannot return to its original anatomical position, making it impossible for the patient to close the mouth. A 22-year-old female patient complaining of succes sive episodes of mandibular dislocation, characterizing the condition of dislocation redicivant TMJ. Surgical treatment was performed with the installation of 2.0 mm double T-shaped titanium miniplates with approximately 90° curvature in the region of articular eminence. After 8 months, the patient has no complaints, no signs of facial nerve damage and no episodes of dislocation. TMJ dislocation is a socially and psychologically distressing clinical condition, being the second most frequent dislocation in the body and with higher incidence in female patients. Key features are inability to close the mouth, pre auricular cutaneous depression, excessive salivation, and tense and spasmodic masticatory muscles. In this case, the patient presented severe relapsing dislocations, along with anxiety and social anguish. The use of plates acts as a mechanical barrier for condylar movements, avoiding hyperexcussion, being a less aggressive and reversible procedure, having only the disadvantage of the possibility of plate frac ture. The technique used with the objective of limiting condyle movement, among the surgical options, is a more conservative technique... (AU)

Differentiation of relapsing-remitting and secondary progressive multiple sclerosis: a magnetic resonance spectroscopy study based on machine learning / Diferenciação de esclerose múltipla recorrente-remitente e progressiva secundária: um estudo de ressonância magnética com espectroscopia baseado em aprendizado de máquina

ABSTRACT Introduction: Magnetic resonance imaging (MRI) is the most important tool for diagnosis and follow-up in multiple sclerosis (MS). The discrimination of relapsing-remitting MS (RRMS) from secondary progressive MS (SPMS) is clinically difficult, and developing the proposal presented in this study would contribute to the process. Objective: This study aimed to ensure the automatic classification of healthy controls, RRMS, and SPMS by using MR spectroscopy and machine learning methods. Methods: MR spectroscopy (MRS) was performed on a total of 91 participants, distributed into healthy controls (n=30), RRMS (n=36), and SPMS (n=25). Firstly, MRS metabolites were identified using signal processing techniques. Secondly, feature extraction was performed based on MRS Spectra. N-acetylaspartate (NAA) was the most significant metabolite in differentiating MS types. Lastly, binary classifications (healthy controls-RRMS and RRMS-SPMS) were carried out according to features obtained by the Support Vector Machine algorithm. Results: RRMS cases were differentiated from healthy controls with 85% accuracy, 90.91% sensitivity, and 77.78% specificity. RRMS and SPMS were classified with 83.33% accuracy, 81.81% sensitivity, and 85.71% specificity. Conclusions: A combined analysis of MRS and computer-aided diagnosis may be useful as a complementary imaging technique to determine MS types.

RESUMO Introdução: A ressonância magnética é a ferramenta mais importante para o diagnóstico e acompanhamento na EM. A transição da EM recorrente-remitente (EMRR) para a EM progressiva secundária (EMPS) é clinicamente difícil e seria importante desenvolver a proposta apresentada neste estudo a fim de contribuir com o processo. Objetivo: o objetivo deste estudo foi garantir a classificação automática de grupo controle saudável, EMRR e EMPS usando a RM com espectroscopia e métodos de aprendizado de máquina. Métodos: Os exames de RM com espectroscopia foram realizados em um total de 91 amostras com grupo controle saudável (n=30), EMRR (n=36) e EMPS (n=25). Em primeiro lugar, os metabólitos da RM com espectroscopia foram identificados usando técnicas de processamento de sinal. Em segundo lugar, a extração de recursos foi realizada a partir do MRS Spectra. O NAA foi determinado como o metabólito mais significativo na diferenciação dos tipos de MS. Por fim, as classificações binárias (Healthy Control Group-RRMS e RRMS-SPMS) foram realizadas de acordo com as características obtidas por meio do algoritmo Support Vector Machine. Resultados: Os casos de EMRR e do grupo de controle saudável foram diferenciados entre si com 85% de acerto, 90,91% de sensibilidade e 77,78% de especificidade, respectivamente. A EMRR e a EMPS foram classificadas com 83,33% de acurácia, 81,81% de sensibilidade e 85,71% de especificidade, respectivamente. Conclusões: Uma análise combinada de RM com espectroscopia e abordagem de diagnóstico auxiliado por computador pode ser útil como uma técnica de imagem complementar na determinação dos tipos de EM.

Policondritis recidivante: manifestaciones clínicas y tratamiento / Recurrent polychondritis. Clinical, diagnosis and treatment

La policondritis recidivante es una enfermedad rara caracterizada por la inflamación recurrente del cartílago y otros tejidos en todo el cuerpo. La afectación del oído es la característica más común, pero puede afectar otras áreas del cuerpo, incluidos el cartílago costal, los ojos, la nariz, las vías respiratorias, el corazón, el sistema vascular, la piel, las articulaciones, los riñones y el sistema nervioso. Los signos y síntomas varían de persona a persona según las partes del cuerpo afectadas. La causa subyacente exacta de la policondritis recidivante se desconoce, aunque los científicos sospechan que se trata de una enfermedad autoinmune. Las complicaciones respiratorias (colapso de la tráquea e infecciones) son la causa más común de muerte, seguidas de la afectación cardiovascular. Los objetivos principales del tratamiento son aliviar los síntomas actuales y preservar la estructura del cartílago afectado. Gracias a las mejoras en el tratamiento, en los últimos años las tasas de supervivencia han aumentado, incluso después de 10 años(AU)

Recurrent polychondritis is a rare condition characterized by recurrent inflammation of cartilage and other tissues throughout the body. Ear involvement is the most common feature, but a variety of other areas of the body may be compromised, including costal cartilage, eyes, nose, airways, heart, vascular system, skin, joints, kidneys and nervous system. The signs and symptoms vary from person to person depending on the body parts affected. The exact underlying cause of recurrent polychondritis is unknown; however, scientists suspect it is an autoimmune condition. The main goals of treatment for people with recurrent polychondritis are to alleviate current symptoms and preserve the structure of the affected cartilage(AU)

Policondritis recidivante como fenómeno paraneoplásico en paciente con síndrome mielodisplásico / Relapsing Polychondritis as paraneoplastic phenomenon in patient with Myelodysplastic Syndrome

Los síndromes mielodisplásicos son un grupo heterogéneo de enfermedades hematológicas, caracterizadas por hematopoyesis ineficaz con riesgo de progresión a leucemia mieloide aguda. Pueden asociarse a manifestaciones autoinmunes en un 10-30% de los pacientes, apareciendo antes, durante o luego del diagnóstico del trastorno hematológico. La prevalencia de policondritis recidivante como fenómeno paraneoplásico es de 0,7-5,4%, presentándose de forma simultánea en la mayoría de los casos. Otros procesos autoinmunes asociados incluyen: vasculitis sistémica, poliartritis seronegativa, dermatosis neutrofílica, citopenias inmunomediadas, presencia de autoanticuerpos y crioglobulinemia. Reportamos el caso de una mujer de 60 años, sin antecedentes patológicos previos, que presentó un cuadro de policondritis recidivante y vasculitis sistémica asociadas a síndrome mielodisplásico.

Myelodysplastic syndromes are a heterogeneous group of hematological diseases, characterized by ineffective hematopoiesis with risk of progression to acute myeloid leukemia. They can be associated to autoimmune manifestations in 10-30% of patients, appearing before, during or after the diagnosis of the hematological disorder. The prevalence of relapsing polychondritis as a paraneoplastic phenomenon is 0.7-5.4%, occurring simultaneously in the majority of cases. Other associated autoimmune processes include: systemic vasculitis, seronegative polyarthritis, neutrophilic dermatosis, immunomediated cytopenias, presence of autoantibodies and cryoglobulinemia. We report the case of a 60-year-old woman, with no previous medical history, who presented with recurrent polychondritis and systemic vasculitis associated with myelodysplasia.

Policondritis recidivante asociada a enfermedad por IgG4 / Relapsing polychondritis associated with IgG4-related disease

La policondritis recidivante (RP) es un trastorno autoinmune sistémico poco frecuente que se caracteriza por episodio y deterioro progresivo de la inflamación del cartílago. Aproximadamente el 30% de los pacientes con RP tienen enfermedad concurrente. Sin embargo, hay tres casos previos reportados de RP relacionado con enfermedad relacionada con la inmunoglobulina G4 (IgG4-RD). Nosotros presentamos otro caso de una mujer de 37 años que desarrolló RP aproximadamente 1 año antes del diagnóstico de IgG4-RD. La asociación entre ER-IgG4 y RP sigue sin estar clara.

Relapsing polychondritis (RP) is a rare systemic autoimmune disorder characterized by the episodic and progressive deterioration of cartilage inflammation. Approximately 30% patients with RP have concurrent disease. However, there are three cases reports of RP complicated by immunoglobulin G4-related disease (IgG4-RD). Here we report another case of a 37-year-old female who developed RP approximately 1 years before IgG4-RD diagnosis. The association between IgG4-RD and RP remains unclear.

Apego al método de Ponseti por parte de los familiares como determinante en el éxito del tratamiento del pie equinovaro / Adherence to the Ponseti method by family members as a determinant in the success of club foot treatment

Resumen: El pie equinovaro aducto congénito (PEVAC) es uno de los padecimientos más comunes en Ortopedia Pediátrica, el cual se compone del equino del retropié, el varo subastragalino, el aducto del antepié y el cavo del mediopié. El método de Ponseti es el tratamiento universalmente aceptado para el PEVAC; éste consta de tres fases: manipulación y enyesado, tenotomía del tendón de Aquiles y una fase de mantenimiento. El mayor porcentaje de las recaídas se presenta en la fase de mantenimiento; en la mayoría de los casos, está asociado el apego familiar deficiente. Presentamos el caso clínico de un paciente con PEVAC típico, tratado en cuatro ocasiones con el método de Ponseti y que no requirió tratamiento quirúrgico.

Abstract: The clubfoot is one of the most common conditions in Pediatric Orthopedics, may affect each part of the foot and ankle, equinus, varus, and internal rotation of the calcaneum, and true equinus of the ankle are common. The Ponseti method is an universally accepted treatment, consisting of three phases: manipulation and plaster, Achilles tendon tenotomy and maintenance phase. The highest percentage of relapses occurs in the maintenance phase and the deficient family member is associated in most cases. We present a clinical case of a patient with typical clubfoot treated with the Ponseti method on four occasions without the need of surgical treatment.

Policondrite Recidivante: do Diagnóstico ao Tratamento / Relapsing polycondrite: from Diagnosis to Treatment

A policondrite recidivante (PR) é uma doença imunomediada rara, caracterizada por inflamação de cartilagens, predominantemente do pavilhão auricular e articulações periféricas. O diagnóstico é baseado em critérios clínicos e o seu tratamento é dependente da fase da doença e de suas manifestações. Apresentamos o caso de um homem de 45 anos com história de edema e hiperemia em pavilhões auriculares responsivo aos tratamentos clínicos, porém altamente recidivantes. Após o diagnóstico e tratamento definitivos, mantém bom controle dos sintomas. A importância desse relato de caso é demonstrar um caso clássico de PR desde o diagnóstico até o tratamento, evidenciando as manifestações pouco específicas da doença e as suas dificuldades diagnósticas

Relapsing polychondritis (RP) is a rare immune-mediated disease characterized by inflammation of cartilagepredominantly those of the ears and peripheral joints. The diagnosis is based on clinical criteria and the treatment depends on the stage of the disease and its manifestation. We present the case of a 45-year-old man with a history of edema and hyperemia in auricular pavilions responsive to clinical treatment, but highly recurrent. After diagnosis and definitive treatment, a good control of the symptoms was achieved. The importance of this report is to demonstrate a classic case of RP from diagnosis to treatment, evidencing the nonspecific manifestations of the disease and its diagnostic difficulties

Técnica de reconstrucción en roturas recidivantes del tendón patelar / Reconstruction technique in recurrent patellar tendon ruptures

La rotura recidivante del tendón patelar es infrecuente y generalmente asociada a comorbilidad sistémica que altera la interfaz tendón-hueso o a consecuencia de un retorno inadecuado a actividades, previo a completar el proceso de rehabilitación. La reconstrucción quirúrgica se basa en el aumento tendíneo con autoinjertos o aloinjertos. El uso de autoinjertos evita el riesgo de transmisión de enfermedades infecciosas y costos en relación a los aloinjertos y no requiere un segundo tiempo quirúrgico para remover material utilizado en la protección del tendón reconstruido, en el caso de utilizar refuerzos con alambres de cerclaje o cables de acero. Se presenta la reconstrucción del tendón patelar con autoinjerto semitendinoso-gracilis, por ser una técnica validada en la literatura, que restablece la fuerza y la estabilidad del mecanismo extensor de forma costo-efectiva y permite el retorno adecuado a las actividades de la vida diaria.

Recurrent rupture of the patellar tendon is infrequent and usually associated with systemic comorbidity that alters the tendon-bone interface or as a result of an inadequate return to activities, prior to completing the rehabilitation process. Surgical reconstruction is based on tendon augmentation with autografts or allografts. The use of autografts avoids the risk of infectious diseases and costs in relation to allografts and does not require a second surgical time to remove material used in the protection of the reconstructed tendon, in case of using cerclage wires or steel cables reinforcements. Reconstruction of the patellar tendon with semitendinosus-gracilis autograft is presented as a technique validated in the literature, which restores the strength and stability of the extensor mechanism in a cost-effective way and allows adequate return to activities of daily living.

Relapsing polychondritis: prevalence of cardiovascular diseases and its risk factors, and general disease features according to gender / Policondrite recidivante: prevalência de doenças cardiovasculares e seus fatores de risco e características gerais da doença de acordo com o gênero

ABSTRACT The comorbidities in relapsing polychondritis have been scarcely described in the literature. Moreover, apart from a few relapsing polychondritis epidemiological studies, no studies specifically addressing relapsing polychondritis distribution according to gender are available. Therefore, the objectives of the present study were: (a) to analyze the prevalence of cardiovascular diseases and its risk factors in a series of patients with relapsing polychondritis; (b) to determine the influence of gender on relapsing polychondritis. A cross-sectional tertiary single center study evaluating 30 relapsing polychondritis cases from 1990 to 2016 was carried out. To compare comorbidities, 60 healthy individuals matched for age-, gender-, ethnicity- and body mass index were recruited. The mean age of relapsing polychondritis patients was 49.0 ± 12.4 years, the median disease duration 6.0 years, and 70% were women. A higher frequency of arterial hypertension (53.3% vs. 23.3%; p = 0.008) and diabetes mellitus (16.7% vs. 3.3%; p = 0.039) was found in the relapsing polychondritis group, compared to the control group. As an additional analysis, patients were compared according to gender distribution (9 men vs. 21 women). The clinical disease onset features were comparable in both genders. However, over the follow-up period, male patients had a greater prevalence of hearing loss, vestibular disorder and uveitis events, and also received more cyclophosphamide therapy (p < 0.05). There was a high prevalence of arterial hypertension and diabetes mellitus, and the male patients seemed to have worse prognosis than the female patients in the follow up.

RESUMO Há escassez de estudos na literatura sobre as comorbidades na policondrite recidivante (PR). Além disso, exceto por alguns estudos epidemiológicos sobre a PR, não existem trabalhos que analisem especificamente a distribuição da PR de acordo com o gênero. Portanto, os objetivos do presente estudo foram: (a) analisar a prevalência de doenças cardiovasculares e seus fatores de risco em uma série de pacientes com PR; (B) determinar a influência do gênero na PR. Fez-se um estudo transversal unicêntrico que avaliou 30 casos de PR entre 1990 e 2016. Para comparar as comorbidades, foram recrutados 60 indivíduos saudáveis pareados por idade, gênero, etnia e índice de massa corporal. A idade média dos pacientes com PR foi de 49,0 ± 12,4 anos. A duração média da doença foi de 6,0 anos e 70% eram mulheres. Foi observada uma maior frequência de hipertensão arterial (53,3% vs. 23,3%, p = 0,008) e diabetes mellitus (16,7% vs. 3,3%; p = 0,039) no grupo PR em comparação com o grupo controle. Em uma análise adicional, os pacientes foram comparados de acordo com a distribuição de gênero (nove homens versus 21 mulheres). As características clínicas iniciais da doença foram comparáveis em ambos os sexos. No entanto, durante o período de seguimento, os pacientes do sexo masculino tiveram maior prevalência de perda auditiva, envolvimento vestibular e eventos de uveíte e também receberam mais tratamento com ciclofosfamida (p < 0,05). Houve uma alta prevalência de hipertensão arterial e diabetes mellitus e os pacientes do sexo masculino apresentaram pior prognóstico do que as pacientes do sexo feminino no seguimento.

Xantoastrocitoma pleomórfico / Pleomorphic Xanthoastrocytoma

El xantoastrocitoma pleomórfico, por su extrema rareza, conlleva alta complejidad en el diagnóstico histopatológico. Se presenta el caso clínico en un sujeto de sexo masculino, de 40 años, con antecedentes de crisis convulsivas de presentación tardía, secundarias a meningioma atípico grado II localizado en región occipital izquierda, resecado por dos ocasiones en el transcurso de 6 años. Recibió radioterapia a dosis completa luego de la segunda resección. El diagnóstico histopatológico inicial fue meningioma atípico gra-do II. El paciente acude al HCAM por cefalea holocraneal intensa y hemiparesia braquiocrural derecha; en los estudios de resonancia magnética nuclear con gadolinio se observó el crecimiento de una lesión occipi-tal izquierda con edema perilesional que ameritó resección total de la lesión a través de la craniectomía previa. Como hallazgo macroscópico, se describe una masa violácea que infiltra duramadre carente de un plano de clivaje; el estudio histopatológico detalla una neoplasia glial hipercelular con infiltración difusa con reacción inmunohistoquímica intensa para PGAF (proteína glial acida fibrilar), S100 y CD56 en células tumorales, CD34 positivo. KI67 positivo en 3% y P53 débilmente positivo, compatible con xantoastroci-toma pleomórfico WHO II.(AU)

The pleomorphic xantoastrocytoma, due to its extreme rarity, carries high complexity in the histo-pathological diagnosis. The clinical case is presented in a male subject, 40 years old, with a history of sei-zures with late presentation, secondary to atypical meningioma grade II located in the left occipital region, resected twice in the course of 6 years. He received full-dose radiation therapy after the second resection. The initial histopathological diagnosis was atypical meningioma grade II. The patient comes to HCAM due to intense holocranial headache and right brachiocrural hemiparesis; In the gadolinium nuclear magnetic resonance studies the growth of a left occipital lesion with perilesional edema that warranted total resec-tion of the lesion through previous craniectomy was observed. As a macroscopic finding, a violaceous mass is described which infiltrates dura mater lacking a plane of cleavage; The histopathological study details a hypercellular glial neoplasia with diffuse infiltration with intense immunohistochemical reaction for PGAF (glial acidic glial protein), S100 and CD56 in tumor cells, CD34 positive. It was KI67 positive in 3% and P53 weakly positive, compatible with pleomorphic xantoastrocytoma WHO II. (AU)

Comparación de resultados entre hernioplastia inguinal abierta con malla tipo liechtenstein y hernioplasta inguinal videolaparoscópica / Outcome Measures between Open Lichtenstein Technique and laparoscopic TAPP Repair of Inguinal Hernias

Introducción: la hernioplastía es uno de los procedimientos quirúrgicos más comunes que realiza el cirujano alrededor del mundo. En nuestra institución se realizan la hernioplastía tipo Liechtenstein (abierto) y videolaparoscópica tipo TAPP (transabdominal preperitoneal). El objetivo del estudio es comparar los resultados obtenidos utilizando ambos procedimientos. Diseño, lugar y participantes: estudio retrospectivo de 45 pacientes sometidos a uno de los dos procedimientos, durante junio-noviembre 2015, en el Hospital General Juan José Arévalo Bermejo, evaluando la prevalencia de inguinodinia crónica, hernia recidivante, complicaciones y tiempo de retorno a labores. Resultados: No se encontró diferencia, entre el grupo abierto comparado con el videolaparoscópico, en la prevalencia de inguinodinia crónica (21.4% vs 17.7%, p: 0.75), ni en el porcentaje de pacientes que consultó a la emergencia por dolor (8.5% vs 13%, p: 0.55), ni en complicaciones postoperatorias de infección, seroma, rechazo e hidrocele (19.1% vs 30.4%, p: 0.36). Las recidivas de hernia inguinal fueron más comunes en el grupo videolaparoscópico que en el abierto (17.3% vs 2.1%; p: 0.019). El tiempo promedio de retorno a labores fue de 29 días en ambos grupos (p: 1.0) Conclusión: En nuestra institución, ambos procedimientos tiene resultados comparables y probablemente, conforme aumente la experiencia de la hernioplastía videolaparoscópica, la incidencia de recidivas disminuya.

Background: Hernioplasty is one of the most common surgical procedures around the world. In our insttuton hernioplasty is performed with Lichtenstein technique (open) and laparoscopic TAPP (transabdominal preperitoneal) repair. The aim of the study is to compare clinical outcomes between both procedures. Design, Setng, and Partcipants: In this retrospectve study, 45 patents were treated with one of the techniques for hernia repair, between June and November of 2015 at the General Hospital Juan José Arévalo Bermejo. The prevalence of chronic inguinodynia, inguinal hernia recurrence, complicatons and tme to return to normal actvites were compared. Results: There is no statstcal diference between open technique compared with laparoscopic repair, in the prevalence of chronic inguinodynia (21.4% vs 17.7%, p: 0.75), nor in the percentage of patents that were atended in the emergency room for pain (8.5% vs 13%, p: 0.55), nor in postoperatve infectons, seroma formaton, rejecton or hydrocele complicatons (p: 0.36). Inguinal hernia recurrence was more common in the laparoscopic group (17.3% vs 2.1%, p: 0.019). Mean tme to return to work was 29 days in both groups (p: 1.0). Conclusions: In our insttuton both procedures have comparable results and more experience is needed to decrease hernia recurrence.

Abstract: Objective: To analyze the casuistics of left atrial myxoma with emphasis on results and follow-up. Method: We reviewed the clinical records of patients operated in the Hospital Cardiac Myxomas South Central High Specialty (HCSAE) of PEMEX in the last 7 years, with an emphasis on results and follow-up. Results: The analysis showed 10 patients, of whom 60% were female and 40% male, with ages from 12 to 76 years, with a mean age of 50 years. In the clinical characteristics of patients predominated dyspnea in 90%, followed by fatigue (80%) and chest pain (60%). The incidence was 90% for the left atrium and 10% for the right atrium, had tumors less than 3 cm to up to over 10 cm (average of 6 to 7 cm). The pathology report was myxoma in the 100% of cases, the morbidity and early mortality was 0%, with a mean hospital stay of 6 days, and a patient of 12 years of age recurred and underwent surgery five months later. The 5-year survival was 100%. Conclusions: The incidence of myxomas is well known for rare presentation, the experience in this national medical center is one patient for every 350 operations, one case per year with no mortality and excellent survival.

Hernia hiatal recidivante: la visión del cirujano: Revisión de la literatura / Literature Review: A Surgeon’s View of Recurrent Hiatal Hernia

Las hernias hiatales recidivantes constituyen una patología común que generan un reto diagnóstico y terapéutico para cirujanos y gastroenterólogos. Generalmente se presentan de forma asintomática o con síntomas atípicos y se asocian a factores fisiológicos, propios del paciente y de la técnica quirúrgica. Su tratamiento es complejo y dependiendo de la causa de los síntomas pueden requerir manejo médico o quirúrgico. En este artículo, se pretenden definir pautas para la identificación y manejo de esta patología, así como establecer claves para el tratamiento desde un enfoque quirúrgico.

Recurrent hiatal hernias are a common pathology that generate a diagnostic and therapeutic challenge for surgeons and gastroenterologists. They are generally asymptomatic or present with atypical symptoms and are associated with the patient’s own physiological factors and the surgical technique. Treatment is complex and, depending on the cause of the symptoms, will require either medical or surgical management. This article starts from a surgical approach to define guidelines for identification and management of this condition and to establish keys to treatment.

Policondritis recidivante, un desafío diagnóstico / Relapsing Polychondritis, a Constant Challenge

La policondritis recidivante es una enfermedad sistémica, infrecuente, que afecta las estructuras cartilaginosas, predominantemente del pabellón auricular, nariz, articulaciones y árbol traqueobronquial. Se presenta una paciente de sexo femenino de 63 años con historia de estenosis traqueobronquial, condritis clínica, nariz en silla de montar e hipoacusia neurosensorial con diagnóstico de policondritis recidivante. Debido a su baja frecuencia, diagnóstico clínico y similitud con otras enfermedades esta entidad siempre plantea un desafío diagnóstico.

Relapsing Polychronditis is an uncommon, systemic disease that affects the cartilage structures, primarily the elastic cartilage of the ears, nose, joints and the tracheobronchial tree. We present the case of a 63 year-old female with a history of tracheobronchial stenosis, clinical chondritis, saddleback nose and neurosensorial hypoacusis. The diagnosis of Relapsing Polychronditis was reached. Due to its low incidence rate, clinical diagnosis and similarity to other diseases, the diagnosis of this disease always represents a challenge.
