Does the reduction of inferior turbinate affect lower airway functions? / A redução da concha nasal inferior afeta as funções das vias aéreas inferiores?

Abstract Introduction: Although the nose and lungs are separate organs, numerous studies have reported that the entire respiratory system can be considered as a single anatomical and functional unit. The upper and lower airways affect each other either directly or through reflex mechanisms. Objective: In this study, we aimed to evaluate the effects of the radiofrequency ablation of persistent inferior turbinate hypertrophy on nasal and pulmonary function. Methods: Twenty-seven patients with bilateral persistent inferior turbinate hypertrophy without septal deviation were included in this study. All of the patients were evaluated using anterior rhinoscopy, nasal endoscopy, acoustic rhinometry, a visual analogue scale, and flow-sensitive spirometry on the day before and 4 months after the radiofrequency ablation procedure. Results: The post-ablation measurements revealed that the inferior turbinate ablation caused an increase in the mean cross-sectional area and volume of the nose, as well as in the forced expiratory volume in 1 s, forced vital capacity, and peak expiratory flow of the patients. These differences between the pre- and post-ablation results were statistically significant. The post-ablation visual analogue scale scores were lower when compared with the pre-ablation scores, and this difference was also statistically significant. Conclusion: This study demonstrated that the widening of the nasal passage after the reduction of the inferior turbinate size had a favorable effect on the pulmonary function tests.

Resumo Introdução: Embora o nariz e os pulmões sejam órgãos separados, numerosos estudos relataram que todo o sistema respiratório pode ser considerado como uma única unidade anatômica e funcional. As vias aéreas superiores e inferiores afetam uma à outra diretamente ou através de mecanismos reflexos. Objetivo: Avaliar os efeitos da ablação por radiofrequência em conchas nasais inferiores com hipertrofia persistente sobre a função nasal e pulmonar. Método: Foram incluídos neste estudo 27 pacientes com hipertrofia persistente bilateral de conchas inferiores sem desvio septal. Todos os pacientes foram avaliados com rinoscopia anterior, endoscopia nasal, rinometria acústica, escala visual analógica e espirometria sensível ao fluxo no dia anterior e quatro meses após o procedimento de ablação por radiofrequência. Resultados: As medidas pós-ablação demonstraram que a ablação das conchas nasais inferiores resultou em um aumento da área transversal média e do volume do nariz, bem como do volume expiratório forçado em um segundo, da capacidade vital forçada e do fluxo expiratório máximo dos pacientes. Essas diferenças entre os resultados pré e pós-ablação foram estatisticamente significantes. Os escores da escala visual analógica pós-ablação foram menores quando comparados com os escores pré-ablação e essa diferença também foi estatisticamente significante. Conclusão: O alargamento da passagem nasal após a redução do tamanho das conchas nasais inferiores teve efeito favorável nos testes de função pulmonar.

Viability of costochondral graft in temporomandibular joint ankylosis

Temporomandibular joint [TMJ] ankylosis is a very distressing structural condition that causes severe facial disfigurement leading to pathopsychological stress. Impairment of speech, difficulty with mastication, rampant caries, poor oral hygiene, disturbances of facial growth and severely compromised airway are the leading consequences of TMJ ankylosis. Surgical intervention is the widely accepted treatment modality of TMJ ankylosis. Current study was performed on 30 patients for three years [2009-2012] department of Oral and Maxillofacial Surgery, Children Hospital and Department of Nuclear Medicine, Shaukat Khanum Memorial Cancer Hospital and Research Center, Lahore and costochondral graft was used to treat mandibular ankylosis. 21 [70%] patients were males and were divided into age groups of 2-5, 6-12 and 13-18 years. Regarding the side of mandible involved in male patients, unilateral ankylosis was found in 15[50%] and bilateral ankylosis were found in 6[20%] patients. Similarly in female patients, unilateral ankylosis was found in 7[23%] and bilateral ankylosis was seen in 2[7%] patients. Regarding post-operative monitoring of graft, bone scintigraphy was performed one week after the surgery and then after 12 weeks and 16 weeks to assess the viability and uptake of costochondral graft. Tc.99m MDP bone scan was performed in supine position with intravenous administration of 370MBq one week after the placement of graft. Results showed that out of 30 patients, CCG graft was viable in 28[93%] while it was non-viable in 2[7%] patients

Reabilitação na paralisia parcial do plexo braquial / Rehabilitation after partial brachial plexus palsy

Muitas transferências musculares têm sido defendidas para restaurar os movimentos do membro superior após paralisia grave do plexo braquial. A paralisia dos músculos deltoide e supraespinal pode ser tratada por meio de transferência do músculo trapézio. A paralisia dos músculos extensores de punho, mão e dedos, quando o nervo mediano está preservado, pode ser corrigida com emprego dos músculos pronador redondo, flexor ulnar do carpo e palmar longo. Os autores descrevem um caso de reabilitação de paciente portador de lesão parcial antiga do plexo braquial à direita, de predomínio em tronco superior, principalmente da raiz de C6 e de fascículo posterior. Foi evidenciada fraqueza dos músculos deltoide e extensores do punho e dos dedos, sem antecedentes de reparo microcirúrgico do plexo braquial. Foi realizada, inicialmente, cirurgia de transferência tendínea para ganho de extensão de punho, mão e dedos e, após um ano, transferência do músculo trapézio, para estabilização do ombro. O sucesso na transferência para tratamento de paralisia do plexo braquial requereu especialização do cirurgião, motivação do paciente e programa de reabilitação.

A variety of muscle transfer techniques have been proposed to restore motion of the upper extremities following severe brachial plexus palsy. Paralysis of the deltoid and supraspinatus muscles can be treated with transfer of the trapezius muscle. Paralysis of the wrist, hand, and digital extensor muscles can be corrected using the pronator teres, flexor carpi ulnaris, and palmaris longus muscles if the median nerve is preserved. Here we describe the rehabilitation of a patient with an old partial injury to the right brachial plexus that primarily involved the upper trunk from the C6 root to the posterior cord. Weakness of the deltoid muscle, wrist, and digital extensor muscles was observed. Microsurgical repair of the brachial plexus had not been performed. Tendon transfer surgery was performed to improve wrist, hand, and digital extension. One year later, transfer of the trapezius muscle was performed to stabilize the shoulder. The success of muscle transfer in the treatment of the brachial plexus palsy required the surgeon's specialization, the patient's motivation, and a rehabilitation program.

Osteotomía tibial supratuberositaria tipo Maquet en la artrosis medial de la rodilla. Informe preliminar / Supra tuberosity tibial osteotomy of Maquet for treatment of medial osteoarthritis of the knee. Preliminary report

El estudio integral del paciente con artrosis grado III ofrece los parámetros para la indicación de esta cirugía. El motivo de este trabajo es valorar la disminución o retraso de los cambios artríticos secundarios a la enfermedad angular en varo y el dolor después de ella, encontrando que en 44 pacientes, 34 respondieron bien al tratamiento por la corrección de la alineación, descenso de la carga y cura de las microfracturas trabeculares aún cuando nuestro seguimiento fue de 3.5 años
