Disfagia orofaríngea y malformaciones anatómicas / Oropharyngeal dysphagia and anatomical malformations

Introducción: La disfagia orofaríngea o dificultad para la deglución puede ser causada por anomalías anatómicas, incluyendo malformaciones óseas cervicales. La evaluación integral y el tratamiento individualizado, que pueden involucrar a varios especialistas, son cruciales para prevenir complicaciones y mejorar la calidad de vida del paciente y su familia. Se presenta un caso clínico que ilustra la relación entre la disfagia orofaríngea y sus complicaciones en un paciente con malformaciones anatómicas craneocervicales y pulmonares. Caso clínico. Niña de 3 años con antecedentes médicos complejos incluyendo malformación congénita ósea cervical que presenta, a raíz de última intervención quirúrgica a ese nivel, episodios recurrentes de neumonía. Dados los antecedentes, se piensa como primera posibilidad diagnóstica etiología aspirativa, constatándose en el estudio disfagia a líquidos, compensable con adaptación de la dieta. A pesar del adecuado tratamiento de la disfagia, la persistencia de los episodios siempre en la misma localización hace replantearse la etiología. La TAC torácica reveló a ese nivel una malformación pulmonar, sometiéndose de forma exitosa a una lobectomía toracoscópica. Actualmente no ha vuelto a presentar neumonías de repetición y gracias al tratamiento por parte de logopeda ha presentado mejoría progresiva de su disfagia. Conclusiones. La disfagia orofaríngea es un síntoma infradiagnosticado. Es imprescindible que se empiece a codificar en informes y registros. Existen herramientas de cribado que nos facilitan su diagnóstico en cualquier nivel asistencial que deberían ser usadas sobre todo en población de riesgo. Requiere reevaluación periódica por ser un síntoma dinámico.(AU)

Introduction: Oropharyngeal dysphagia, or difficulty swallowing, may be due to anatomic abnormality, including cervical malformations. A comprehensive assessment and an individualized care, which may include multiple specialists, are crucial in preventing complications and improving the quality of life for both the patient and family. A clinical case is presented that illustrates the relationship between oropharyngeal dysphagia and its complications in a patient with craniocervical and pulmonary malformations. Case report. 3-year-old girl with a complex medical history including congenital cervical bone malformation, who presents with recurrent episodes of pneumonia following her last surgical intervention at that level. Given her medical history, aspirational etiology is considered as first diagnostic possibility with studies confirming dysphagia to liquids, compensable with dietary adaptation. Despite adequate treatment of dysphagia the persistence of episodes, always in the same location, makes us reconsider the etiology. The chest CT revealed a pulmonary malformation at that level and the patient underwent a successful thoracoscopic lobectomy. Currently, she has not had recurrent pneumonia and, thanks to treatment by a speech therapist, she has shown progressive improvement in her dysphagia. Conclusions. Oropharyngeal dysphagia is an underdiagnosed symptom. It is essential we begin to codify it in reports and records. There are screening tools to facilitate the diagnosis at any level of health care that should be used especially in at risk population. It requires periodic reevaluation as it is a dynamic symptom.(AU)

Prevalence of Temporal Bone Malformations in Prospective Cochlear Implant Candidates.

Severe to profound Sensorineural Hearing Loss is a challenging medical problem, particularly if this condition is associated with an inner ear anomaly. This case series studies the prevalence of inner ear anomalies among 76 consecutive prospective cochlear implant candidates who presented to our tertiary care hospital over 2 years. Inner ear anomalies were identified in 11 cases with a prevalence rate of 14%. Narrow Internal Auditory Canal (IAC) is the most common inner ear anomaly (5) followed by Mondini (3) and Globular vestibule (3). Combined CT and MRI play an important role in the preoperative assessment of inner ear anomalies which may affect not only the decision to perform the Implant procedure and the prognosis but also the choice of implant and surgical technique.

A case of polymelia associated with syndactyly in Didelphis aurita (Wied-Neuwied, 1826) / Relato de caso de polimelia associada a sindactilia em Didelphis aurita (Wied-Neuwied, 1826)

Abstract In January 2018, a young male of Didelphis aurita (Wied-Neuwied, 1826), the Brazilian common opossum, was admitted for veterinary evaluation at the Recovery Clinic of Wild Animals of Estácio de Sá University, CRAS, in Rio de Janeiro, Brazil, due to the presence of a partially duplicated right hind limb. After x-ray evaluation, polymelia associated with syndactyly was diagnosed. The images revealed the following alterations on the right limb: single femur with increased diameter, two tibiae, two fibulae and absence of hallux. The observed malformations were restricted to the hind right limb, which remains functional. This is the first report of such anomalies in an individual of Didelphis aurita.

Resumo Em janeiro de 2018, um macho jovem de Didelphis aurita (Wied-Neuwied, 1826), o gambá-de-orelha-preta, foi recebido para atendimento veterinário na Clínica de Recuperação de Animais Silvestres (CRAS) da Universidade Estácio de Sá, no Rio de Janeiro, por ser portador de membro posterior direito parcialmente duplicado. Após exame radiográfico, constatou-se a ocorrência de polimelia associada a sindactilia. As imagens radiográficas revelaram as seguintes alterações no membro posterior direito: um fêmur com diâmetro aumentado, duas tíbias, duas fíbulas e ausência de hálux. As malformações observadas restringiram-se apenas ao membro posterior direito, o qual mantém sua funcionalidade. Essas alterações nunca antes foram descritas na espécie Didelphis aurita.

Ionic Colloidal Molding as a Biomimetic Scaffolding Strategy for Uniform Bone Tissue Regeneration.

Inspired by the highly ordered nanostructure of bone, nanodopant composite biomaterials are gaining special attention for their ability to guide bone tissue regeneration through structural and biological cues. However, bone malformation in orthopedic surgery is a lingering issue, partly due to the high surface energy of traditional nanoparticles contributing to aggregation and inhomogeneity. Recently, carboxyl-functionalized synthetic polymers have been shown to mimic the carboxyl-rich surface motifs of non-collagenous proteins in stabilizing hydroxyapatite and directing intrafibrillar mineralization in-vitro. Based on this biomimetic approach, it is herein demonstrated that carboxyl functionalization of poly(lactic-co-glycolic acid) can achieve great material homogeneity in nanocomposites. This ionic colloidal molding method stabilizes hydroxyapatite precursors to confer even nanodopant packing, improving therapeutic outcomes in bone repair by remarkably improving mechanical properties of nanocomposites and optimizing controlled drug release, resulting in better cell in-growth and osteogenic differentiation. Lastly, better controlled biomaterial degradation significantly improved osteointegration, translating to highly regular bone formation with minimal fibrous tissue and increased bone density in rabbit radial defect models. Ionic colloidal molding is a simple yet effective approach of achieving materials homogeneity and modulating crystal nucleation, serving as an excellent biomimetic scaffolding strategy to rebuild natural bone integrity.

Application of technique of stretch and press of ILIZAROV in the treatment of false joint and bone loss in the lower limb by extracorporeal fixation frame

Bony defect of the tibia and femur have been usually seen in our country. Two most serious complications were the nonunion with bone loss. Three main etiologies: open fracture after traffic accident, tumor of the bone and chronic osteomyelitis. Classic treatment method for nonunion with bone loss of lower limb have been used autografts, allograts, Hahn’s method or free vascularized bone result bone healing. Those treatment still have complication: infection, the bone frafts fracture and deficit recover of the bone’s length on the lower limb. Since May 1994 - May 2000, in the Orthopaedics Department of Nhan Dan Gia Dinh hospital, Ho Chi Minh City, 36 patients involving nonunion with extensive bone loss were treated by extracorporeal fixation system with principle: stable, may lengthen for the long bone which follows lliraroz’s method. Result: 24 cases are good, 9 cases are medium, 3 cases are bad.
