Clinical registries are increasingly common and have value in conditions such as congenital upper limb differences where collection of adequate data for scientific study can be challenging due to small numbers and clinical, surgical and psychosocial heterogeneity. This article discusses the motivation, purpose and development of the Australian Hand Differences Register before examining some of the challenges faced during its implementation and considering limitations of registry-derived data. Level V (Diagnostic).

Congenital dorsal curvature of the distal phalanx has been previously described as 'reverse Kirner' or 'ski-jump' deformity. This report describes bilateral occurrence in the thumbs. A 13-year-old male presented with difficulty caring for his thumbnails and in picking up small objects.

It is often thought that that age remains a limit to free tissue transfers, with younger patients having smaller vessels, making the operation technically challenging. In this case report, we discuss the youngest and smallest recorded case of a free flap reconstruction.

We systematically study SnSe monolayer islands grown by molecular beam epitaxy, especially the effect of annealing temperature on shape and morphology of the edges. Characterization of the samples by scanning tunneling microscopy reveals that the shape of the islands changes from fractal-dendritic after deposition at room temperature to a compact rhombic shape through annealing, but ripening processes are absent up to the desorption temperature.

Furthermore, AML and MDS patients suffer frequent infections because of disease-related impaired immunity. However, the role of infections in the development and progression of AML and MDS remains poorly understood.

Although many nerve injuries improve with the reduction and stabilization of the fracture, the speed and completeness of recovery are unclear. This study investigates median nerve recovery time using the serial examination.

Often, definitive circular frame stabilisation is delayed until the soft tissue envelope is secure to allow access for further soft tissue reconstruction if required. This delay has potential clinical and cost implications.

Data of 48 FA patients at the National Cancer Institute were reviewed focusing on age at diagnosis, type and severity of limb difference and any potential association with other known clinical anomalies that are part of the FA phenotype, specifically VACTERL-H and PHENOS. Twenty-eight patients had an upper limb difference, which always included thumb hypoplasia.

This case report outlines the use of the distal pedicle of the sartorius muscle in the coverage of a large bony and soft tissue defects of the distal femur in a trauma setting.

Limb salvage was accomplished in the form of a single bone forearm fusion utilising Masquelet's two-stage induced membrane technique to reconstruct the segmental bone defect. The patient proceeded to uneventful bony union by 6 months and returned to driving and riding a quadbike.

The Australian Hand Difference Register (AHDR) provides a national database of children born with a CoULD and aims to facilitate research and improve health care for affected children. Using data from the first 3 years of its operation, we analysed the demographic and clinical features of participating families, including type of CoULDs and the frequency of pre-natal and syndromic diagnoses.

Bone mass but not cross-sectional moment of inertia was better maintained in power than endurance athletes over time, particularly in men and independent of changes in performance.
Objective: Assessment of effects of sex and athletic discipline (lower limb power events, e.

Introduction: Approximately 2% of the population are anticoagulated and over 50% of over 65-year-olds are prescribed antiplatelet agents. Several systematic reviews have shown the safety of interrupting anticoagulation and antiplatelets for non-emergency surgery, although such reviews excluded upper limb procedures and represents the rationale for this review.
Methods: The literature was systematically searched for studies concerning the outcomes of adult hand or wrist surgery on patients receiving anticoagulation or antiplatelet agents in direct comparison to controls (no anticoagulation or antiplatelet agents, or interruption of either).
This short review will be concerned with the literature that has developed connected with the immunogenetic and tissue compatibility aspects of hand transplantation and will also draw on connected work in the more general area of vascularized composite allotransplantation (VCA) which includes face, abdominal wall uterus and larynx.

Since programme launch in 2013, ten procedures in six individuals have been performed involving unilateral or bilateral transplants. The multi-disciplinary team that delivers the programme includes the transplant immunology service.
View Article and Find Full Text PDFTranscription and pre-mRNA splicing are key steps in the control of gene expression and mutations in genes regulating each of these processes are common in leukaemia. Despite the frequent overlap of mutations affecting epigenetic regulation and splicing in leukaemia, how these processes influence one another to promote leukaemogenesis is not understood and, to our knowledge, there is no functional evidence that mutations in RNA splicing factors initiate leukaemia. Here, through analyses of transcriptomes from 982 patients with acute myeloid leukaemia, we identified frequent overlap of mutations in IDH2 and SRSF2 that together promote leukaemogenesis through coordinated effects on the epigenome and RNA splicing.

Objective: Energy metabolism and insulin action follow a diurnal rhythm. It is therefore important that investigations into dysregulation of these pathways are relevant to the physiology of this diurnal rhythm.
Methods: We examined glucose uptake, markers of insulin action, and the phosphorylation of insulin signaling intermediates in muscle of chow and high fat, high sucrose (HFHS) diet-fed rats over the normal diurnal cycle.
Background: Donor-specific antibodies (DSAs) have a strong negative correlation with long-term survival in solid organ transplantation. Although the clinical significance of DSA and antibody-mediated rejection (AMR) in upper extremity transplantation (UET) remains to be established, a growing number of single-center reports indicate their presence and potential clinical impact.
Methods: We present a multicenter study assessing the occurrence and significance of alloantibodies in UET in reference to immunological parameters and functional outcome.
Which is more enjoyable: trying to think enjoyable thoughts or doing everyday solitary activities? Wilson et al. (2014) found that American participants much preferred solitary everyday activities, such as reading or watching TV, to thinking for pleasure. To see whether this preference generalized outside of the United States, we replicated the study with 2,557 participants from 12 sites in 11 countries.
