PURPOSE: Radial head arthroplasty (RHA) is a viable treatment for complex radial head fracture. Whereas elbow stability and function is typically restored at short- to mid-term follow-up, the outcome in higher-demand populations is not well defined. We sought to characterize the functional and occupational outcomes following RHA in an active duty military population with intense upper extremity demands. METHODS: We retrospectively reviewed the records of all U.S...

BACKGROUND: Therapeutic management of upper extremity (UE) function of boys and men with Duchenne Muscular Dystrophy (DMD) requires sensitive and objective assessment. Therefore, we aimed to measure physiologic UE function of healthy subjects and DMD patients in different disease stages, and to evaluate the relation between these physiologic measures and functional UE scales. METHODS: Twenty-three DMD patients and twenty healthy controls (7-23 years) participated in this explorative case-control study...

A schwannoma is a benign nerve sheath tumor derived from Schwann cells. They are usually small and solitary tumors more frequently localized in cranial nerves and the spinal cord and rarely in the limbs. Some cases have been reported involving extremities (mainly the upper ones) but with a small size. Cases of big size schwannomas unrelated to a neurofibromatosis are very rare. We report the case of a 25 year old patient, with a giant schwannoma which invaded the ischiatic region reaching the triceps surae.

Wetlands in the region of Southern Ontario, Canada have declined substantially from their historic area. Existing regulations and programs have not abated this decline. However, reversing this trend by protecting or restoring wetlands will increase the supply of important ecosystem services. In particular, these actions will contribute to moderating the impacts of extreme weather predicted to result from climate change as well as reducing phosphorous loads in Lake Erie and ensuing eutrophication. Since the majority of land in the region is privately owned, landowners can play an important role...

INTRODUCTION: We report a case of spinal cord infarct as a result of suspected fibrocartilaginous embolism (FCE). CASE PRESENTATION: A 23-year-old man presented with sudden onset cervical and upper back pain followed by progressive weakness in his extremities after throwing a baseball. History, neurologic examination and spinal cord imaging were consistent with spinal cord infarct. We believe the cause was from FCE. DISCUSSION: Though rare, physicians should be familiar with this diagnosis and the proposed mechanisms...

INTRODUCTION: The underlying causes of longitudinally extensive transverse myelitis (LETM) are broad and include inflammatory processes, compression and spinal dural arteriovenous fistula (SDAVF). Presenting symptoms of SDAVF are nonspecific and often go misdiagnosed. Acute clinical deterioration from SDAVF has been described following exertion or valsalva. However, deterioration has been recently recognized following steroid administration and may contribute to increased morbidity. CASE PRESENTATION: We describe a 63-year-old woman with a 2-year history of intermittent lower extremity numbness and back pain, lumbar stenosis, who presented with subacute worsening of symptoms following a course of oral steroids for an upper respiratory infection...

The axillary reverse mapping (ARM) technique has been described as an attempt to map and preserve the upper extremity lymphatic drainage during axillary lymph node dissection (ALND) and/or SLNB. This technique is based on the hypothesis that the lymphatic pathway from the upper extremity is not involved by metastasis from primary breast cancer. The ARM node/s however, has been found, in various studies, to be involved with metastatic foci in patients with extensive axillary lymph node metastases. Therefore, the oncological safety of this procedure has not yet been determined...

Coral reefs are threatened by climate change as coral-algal symbioses are currently living close to their upper thermal limits. The resilience of the algal partner plays a key role in determining the thermal tolerance of the coral holobiont and therefore, understanding the acclimatory limits of present day coral-algal symbioses is fundamental to forecasting corals' responses to climate change. This study characterised the symbiont community in a highly variable and thermally extreme (Max = 37.5 °C, Min = 16...

OBJECTIVE: Vascular closure devices have been used to achieve hemostasis of percutaneous access sites following endovascular procedures, with reported decreased time for arterial control as well as decreased time to ambulation. We sought to determine rates and risk factors of postoperative bleeding complications and failures using these devices from a single institution experienced in the use of vascular closure devices. METHODS: All patients undergoing arterial endovascular procedures with percutaneous access between March 2010 and October 2015 at a single institution were identified and analyzed (n=894)...

BACKGROUND: Shoulder and elbow injuries are commonplace in high school baseball. Although altered shoulder range of motion (ROM) and humeral retrotorsion angles have been associated with injuries, the efficacy of preseason screening of these characteristics remains controversial. METHODS: We conducted preseason screenings for shoulder internal and external rotation ROM and humeral retrotorsion on 832 high school baseball players and tracked their exposure and incidence on throwing-related shoulder and elbow injuries during a subsequent season...

BACKGROUND: Low back pain (LBP) is a common problem that can contribute to motor dysfunction. Previous studies reporting the changes in kinematic characteristics caused by LBP present conflicting results. This study aimed to apply the multisegmental spinal model to investigate the kinematic changes in patients with lumbar disc herniation (LDH) during five activities of daily living (ADLs). METHODS: Twenty-six healthy subjects and 7 LDH patients participated in this study and performed level walking, stair climbing, trunk flexion, and ipsilateral and contralateral pickups...

Disseminated superficial actinic porokeratosis (DSAP), the most common type of porokeratosis, usually presents as large numbers of lesions on sun-exposed skin. Although several treatment options including corticosteroids, keratolytics, 5-fluorouracil, imiquimod, vitamin D3 analogues, cryotherapy, curettage, laser therapy and dermabrasion may be considered, there is no evidence-based standard treatment.(1-2) Patient 1 was a 26-year-old female who presented with a 2-year history of progressive scaly macules on both upper and lower extremities...

The evolution of filter feeding in baleen whales (Mysticeti) facilitated a wide range of ecological diversity and extreme gigantism. The innovation of filter feeding evolved in a shift from a mineralized upper and lower dentition in stem mysticetes to keratinous baleen plates that hang only from the roof of the mouth in extant species, which are all edentulous as adults. While all extant mysticetes are born with a mandible lacking a specialized feeding structure (i.e., baleen), the bony surface retains small foramina with elongated sulci that often merge together in what has been termed the alveolar gutter...

Essential Tremor is the most common neurological movement disorder. This progressive disease causes uncontrollable rhythmic motions-most often affecting the patient's dominant upper extremity-that occur during volitional movement and make it difficult for the patient to perform everyday tasks. Medication may also become ineffective as the disorder progresses. For many patients, deep brain stimulation (DBS) of the thalamus is an effective means of treating this condition when medication fails. In current use, however, clinicians set the patient's stimulator to apply stimulation at all times-whether it is needed or not...
