Malignant peripheral nerve sheath tumor of the breast: case report

<p>Abstract</p> <p>Background</p> <p>Malignant peripheral nerve sheath tumor is a rare soft tissue sarcoma of ectomesenchymal origin. It is the malignant counterpart of benign soft tissue tumors like neurofibromas and schwannomas and may often follow them. Common sites include deeper soft tissues, usually in the proximity of a nerve trunk. Breast is an extremely rare location of this lesion and presentation as a breast lump in the absence of pain or previous benign neural tumor is even rarer.</p> <p>Case presentation</p> <p>A 38-year-old female presented with complaints of painless, hard breast lump for three months which was clinically suspected to be a ductal carcinoma with inconclusive fine needle aspiration cytology. Histopathology revealed a malignant spindle cell tumor which was confirmed to be malignant peripheral nerve sheath tumor on the basis of immunopositivity for vimentin, neurone specific enolase and S-100.</p> <p>Conclusion</p> <p>To the best of our knowledge only six such case reports have been published in literature. The differential diagnosis of malignant peripheral nerve sheath tumor should be considered by the clinician as well as the pathologists in the work-up of a breast neoplasm as treatment and prognosis of this rare malignancy is different.</p

The influence of staff training and education on prosthetic and orthotic service quality : a scoping review

Background: Education and training in prosthetics and orthotics typically comply with International Society for Prosthetics and Orthotics standards based on three categories of prosthetic and orthotic professionals. Objective: This scoping study sought to describe the evidence base available to answer the question, How are prosthetic and orthotic services influenced by the training of staff providing them? Study design: Scoping review. Methods: A structured search of the peer-reviewed literature catalogued in major electronic databases yielded 3039 papers. Following review of title and abstract, 93 articles were considered relevant. Full-text review reduced this number to 25. Results: Only two articles were identified as providing direct evidence of the effects of training and education on service provision. While both suggested that there was an impact, it is difficult to see how the more specific conclusions of either could be generalised. The other 23 articles provide a useful background to a range of issues including the specification of competencies that training programmes should deliver (3 articles), descriptions of a range of training programmes and the effects of training and education on student knowledge and skills. Conclusion: Although it is considered axiomatic, the service quality is dependent on practitioner education and training. There is insufficient evidence to establish whether levels of training and education in prosthetics and orthotics have an effect on the quality of prosthetic and orthotic services. Clinical relevance: There is very little evidence about the effects of training and education of prosthetists and orthotists on service quality. While this is a somewhat negative finding, we feel that it is important to bring this to the attention of the prosthetics and orthotics community

Callous-unemotional traits moderate the relation between prenatal testosterone (2D:4D) and externalising behaviours in children

Children who exhibit callous-unemotional (CU) traits are identified as developing particularly severe forms of externalising behaviours (EB). A number of risk factors have been identified in the development of CU traits, including biological, physiological, and genetic factors. However, prenatal testosterone (PT) remains un-investigated, yet could signal fetal programming of a combination of CU/EB. Using the 2D:4D digit ratio, the current study examined whether CU traits moderated the relationship between PT and EB. Hand scans were obtained from 79 children aged between 5 and 6 years old whose parents completed the parent report ICU (Inventory of Callous Unemotional Traits) and SDQ (Strengths and Difficulties Questionnaire). CU traits were found to moderate the relationship between PT and EB so that children who were exposed to increased PT and were higher in CU traits exhibited more EB. Findings emphasize the importance of recognising that vulnerability for EB that is accompanied by callousness may arise before birth

A novel percutaneous double-lumen stent graft technique for treatment of chronic type B aortic dissection under local anesthesia

We present a novel endovascular technique for treatment of chronic dissection with abdominal aortic aneurysm whereby multiple overlapping stent grafts are placed in parallel in the true and false lumens in a 65-year-old woman. The use of multiple stent grafts within each lumen allowed total aneurysm exclusion and prevention of false lumen reperfusion while the parallel placement preserved flow in both lower extremities. Postoperative imaging showed complete exclusion of the aneurysm with patency of all aortic branches and no evidence of endoleak. The success of this novel procedure demonstrates feasibility of parallel stent graft implantation in both true and false lumens

Changes in treatment patterns of thoracoabdominal aortic aneurysms in the United StatesCentral MessagePerspective

Background: The introduction of endovascular repair provides an alternative to traditional open repair of thoracoabdominal aortic aneurysms (TAAA). Its utility is not well defined, however. Using a national database, we studied the treatment patterns and outcomes of TAAA to gain insight into its contemporary surgical practice in the United States. Methods: Records of TAAA patients who received endovascular and open repair were retrieved from the 2002 to 2018 National Inpatient Sample database. Each cohort was stratified into 4 age groups: ≤50, 51 to 60, 61 to 70, and >70 years. Patient characteristics and in-hospital outcomes were compared between the 2 repair modalities. Temporal trends were investigated. Results: Endovascular repair use increased steadily, whereas open repair volume remained stable until 2012, before declining by 50% by 2018. This appears to be associated with a declining number of open repairs in patients age >60 years. Patients who underwent endovascular repair were older and had a higher Charlson Comorbidity Index (mean, 2.8 ± 1.7 vs 2.5 ± 1.5; P 60 years but not for patients age ≤60 years. Conclusions: There has been a shift in the treatment of TAAA in the United States from open repair–dominant to endovascular repair–dominant. It has increased surgical access for older and more comorbid patients and has led to a decline in the use of open repair while lowering in-hospital mortality

Estudio comparativo del tratamiento ortésico en las fracturas toraco-lumbosacras según la gravedad del trauma Estudo comparativo do tratamento ortótico nas fraturas toraco-lombosacro segundo a gravidade do trauma Comparative study on orthotic treatment of thoraco-lumbo-sacral fractures according to severity of trauma

OBJETIVO: Determinar si la gravedad del trauma en lesiones toracolumbosacras mayores estables permite decidir la selección del tipo de ortesis en un tratamiento ortopédico. MÉTODOS: Estudio Retrospectivo de casos 12/1990 - 12/2006 (16 años). Criterios de Selección: 1) Seguimiento mínimo: 2 años. 2) Estudios radiológicos convencionales completos. 3) Ausencia de Litigio. 4) Tratamiento ortésico con TLSO a medida para los traumas de alta energía cinética y con ortesis prefabricadas para los de baja energía. 5) Tratamiento efectuado o supervisado por el autor Sénior. Evaluación por observadores independientes de Parámetros Geométricos (ángulo de Cobb sagital, cifosis vertebral, grado de colapso vertebral) pretratamiento y seguimiento en Rx simple, y Parámetros Funcionales (Dolor según SRS, Índice de Oswestry, Retorno a la Actividad Previa). Subdivisión de los diferentes tipos de fracturas (según AO y Denis) en Alta (Grupo A) y Baja Energía [Grupo B] de acuerdo con la energía cinética del trauma. Comparación de Parámetros Geométricos con Grupo Control. Análisis Estadístico: chi cuadrado y t-test de Student. RESULTADOS: 41 pacientes (44 fracturas] tratados (23 mujeres/18 varones), con 25 fracturas Grupo "A", y 19 Grupo "B". Edad promedio: 46 años (12 - 83). Seguimiento promedio: 4,5 años (2.2 - 15.5). Localización predominante: T11 - L2. Tipos Predominantes: tipo A (AO) o por compresión y por estallido. No hubo diferencias significativas en las mediciones efectuadas en cada grupo pretratamiento y al seguimiento. La única diferencia significativa entre grupos fue en la cifosis vertebral inicial tanto en general como según la clasificación AO entre los tipos A de alta y baja energía. La comparación al seguimiento de los parámetros geométricos entre grupo control y grupos A y B así como entre grupo control y cada tipo (AO/Denis) subdivididos en alta o baja energía, arrojó siempre diferencias significativas. Los parámetros funcionales al seguimiento mostraron siempre puntuaciones promedio buenas, con variaciones significativas entre grupos A y B. El retorno a la actividad previa fue del 90,6%, sin diferencias entre trabajadores de esfuerzo físico y de escritorio. CONCLUSIONES: Es posible lograr un Resultado Clínico Funcional satisfactorio a mediano plazo en las lesiones toracolumbosacras mayores estables seleccionando el tipo de ortesis según que el trauma sea de alta o baja energía cinética. Los resultados clínicos funcionales parecen ser mejores en los casos de Trauma de Alta Energía. Sin embargo, este tratamiento no mejora ni empeora los parámetros radiológicos sagitales.<br>OBJETIVO: Determinar se a gravidade do trauma toraco-lombo-sacro estável permite decidir o tipo de órteses na seleção do tratamento ortopédico.

Subdivisão de diferentes tipos de fraturas (AO e Denis) proporcional à energia cinética do trauma, em (grupo A) alta energia e (grupo B) baixa energia. Comparação com o grupo de controle. Análise estatística: qui quadrado e teste tStudent. RESULTADOS: Estudos até 41 pacientes (44 fraturas, 23 mulheres/18 homens), 25 fraturas grupo "A" e 19 grupo "B". Média de idade: 46 anos (12-83). Seguimento médio: 4,5 anos (2,2 -15,5). Localização predominante: T11 - L2. Tipos predominantes: Tipo A (AO) ou por compressão e estalido. Não houve nenhuma diferença significativa entre medições iniciais e seguimento. A única diferença significativa entre os grupos foi a cifose inicial da coluna vertebral. Sempre houve dife renças na comparação dos parâmetros geométricos do grupo controle e os grupos A e B, e entre o grupo controle e cada tipo (AO/Denis) subdividido em alta ou baixa energia. As pontuações dos parâmetros funcionais finais sempre foram boas, com variações significativas entre os grupos A e B. CONCLUSÕES: É possível um bom resultado funcional em lesões toraco-lombo-sacrais estáveis, selecionando o tipo de órteses de acordo com a energia cinética do trauma. Esses resultados parecem ser melhores em traumas de alta energia tratados com dispositivos ortopédicos feitos à medida. No entanto, o tratamento ortésico diferenciado de acordo com a energia do trauma não altera os parâmetros radiológicos sagitais.<br>OBJECTIVE: To determine whether the severity of stable thoraco-lumbo-sacral trauma is useful for deciding the selection of brace type in orthopedic treatment. METHODS: Retrospective study (16 years length). Inclusion criteria: 1) Minimum follow-up: 2 years. 2) Complete conventional radiologic studies. 3) no litigation. 4) TLSO custom-made treatment for high kinetic energy trauma and pre-fabricated orthoses for low energy one. 5) Treatment performed or supervised by the senior author. Evaluation by independent observers of geometric Parameters (sagittal Cobb, vertebral kyphosis, anterior vertebral collapse) initially and at follow-up, and Functional Parameters (SRS pain scale, Oswestry Index, Return to Previous Activity). Subdivision of different fractures types (of AO and Denis classifications) in High (group A) and Low Energy (group b) according to the amount of kinetic energy of trauma. Comparison with a control group. Statistical analysis: chi square and Student t-test. RESULTS: Forty-one patients were studied (44 fractures, 23 females/18 males), 25 fractures group A and 19 group b. Average age: 46 years (12 - 83). Average follow-up: 4.5 years (2.2 - 15.5). Predominant location: T11 - L2. Predominant types: Type A (AO) or compression and burst. There were no significant differences between initial and follow-up measurements. The only significant difference between groups was in the initial vertebral kyphosis. However, there were always differences when comparing the geometric Parameters between control group and groups A and b, and between control group and each type (AO/Denis) subdivided into high or low energy. The final functional parameters scores were always good, with significant variations between groups A and b. CONCLUSIONS: A satisfactory functional result in stable thoraco-lumbo-sacral injuries is possible by selecting the type of brace according to the kinetic energy involved. Results appear to be better in High Energy Trauma treated with custom-made orthosis. However, the orthotic treatment according to trauma energy does not change the sagittal radiographic parameters
