Ectopic Salivary Gland - A Possible Differential Diagnosis of a Branchial Cleft Cyst.

Branchial cleft cysts or fistulae are common in pediatric surgical pathology and are cured by surgery. Lesions in this area may not show the classical features of a cyst or duct lined by squamous or respiratory epithelium and other differential diagnoses should be considered. A seven-year-old otherwise healthy boy presented with bilateral swelling of the lower neck and reported intermittent secretion of clear fluid on the right side.

Evolution of muscle coordination and mechanical output following four weeks of arm cranking submaximal training.

Unlabelled: Muscle synergies is extensively studied to understand how the neuromusculoskeletal system deals with abundancy. The synergies represent covariant muscles that acts as building blocks for movement production. Nevertheless, little is known on how those synergies evolve following training, learning and expertise.

Subject specific muscle synergies and mechanical output during cycling with arms or legs.

Background: Upper (UL) and lower limb (LL) cycling is extensively used for several applications, especially for rehabilitation for which neuromuscular interactions between UL and LL have been shown. Nevertheless, the knowledge on the muscular coordination modality for UL is poorly investigated and it is still not known whether those mechanisms are similar or different to those of LL. The aim of this study was thus to put in evidence common coordination mechanism between UL and LL during cycling by investigating the mechanical output and the underlying muscle coordination using synergy analysis.

A new technique for correction of leg length discrepancies in combination with complex axis deformities of the lower limb using a lengthening nail and a locking plate.

Purpose: Intramedullary lengthening nails are an accepted alternative to external fixators but are limited by anatomical preconditions. Therefore, to date the use of external fixators is sometimes inevitable. We report on a new technique for correction of combined limb length discrepancies and complex axis deformities using solely internal devices - a lengthening nail and a locking plate.

Non-vascularised fibula grafts for reconstruction of segmental and hemicortical bone defects following meta- /diaphyseal tumour resection at the extremities.

Background: The reconstruction of meta-/diaphyseal bone defects following bone tumour resection is challenging, and biological treatment options should be applied whenever possible, especially in benign lesions and early stage sarcomas. We aimed to evaluate the results of segmental (SR) and hemicortical reconstructions (HR) at the extremities using non-vascularised fibula grafts.

Methods: We retrospectively enrolled 36 patients who were treated with non-vascularised fibula reconstructions (15 SR, 21 HR) after bone tumour resection (15 malignant, 21 benign).

Intramedullary lengthening nails: can we also correct deformities?

Unlike external fixators, the use of solid intramedullary lengthening nails is restricted to defined anatomical preconditions, such as an adequate bone length. Furthermore, all deformity corrections except the lengthening procedure have to be implemented intraoperatively and cannot be adjusted postoperatively. Conversely, even complex deformity corrections can be performed using intramedullary devices after a thorough preoperative planning.

Putting patient participation into practice in pediatrics-results from a qualitative study in pediatric oncology.

Unlabelled: Adequate participation of children and adolescents in their healthcare is a value underlined by several professional associations. However, little guidance exists as to how this principle can be successfully translated into practice. A total of 52 semi-structured interviews were carried out with 19 parents, 17 children, and 16 pediatric oncologists.

Only a Touch of the Flu? The Simultaneous Manifestation of Acute Necrotizing Encephalopathy in Two Consanguineous Patients.

This case report describes the simultaneous manifestation of acute necrotizing encephalopathy in 2 consanguineous patients after infection with influenza B based on the autosomal dominant missense mutation of the RANBP2-gene. Differential diagnosis of acute encephalopathy, clinical and radiological clues, and treatment strategies are outlined.
