An Examination of Visually Impaired Individuals' Uncertainty Management.

Being visually impaired or legally blind (having vision that is uncorrectable or cannot be corrected to a legally acceptable level) is inherently uncertain. Although uncertainty can result in positive, negative, or neutral consequences, little is known about how uncertainty is experienced and negotiated in this understudied population. Thus, through in-depth, semi-structured interviews of 24 individuals with a visual impairment, we apply uncertainty management theory (UMT) to examine the communication strategies visually impaired individuals used to manage the personal, vision-related, and social uncertainty they experienced.

A Case Report of Unicompartmental Knee Arthroplasty Fracture of the Femoral Component.

Introduction: Unicompartmental knee arthroplasty (UKA) is performed with yearly rate of 9% in UK, and <8% in USA. It has been shown to be a successful and less invasive alternative to complete knee arthroplasty in certain patients total knee arthroplasty (TKA). Fracture of the femoral component after (UKA) has never been reported in the literature.

High-speed running density in collegiate women's lacrosse.

High-speed running density (HSRd) is the ratio of high-speed efforts and distance covered. This study aimed to evaluate differences in HSRd between training, games, and among positions in collegiate women's lacrosse, and correlate HSRd with other training metrics. Data were collected during a collegiate training year (practices n = 162, games n = 14) through players (n = 25) wearing microtechnology.

Atraumatic Scapular Spine Fracture: A Rare Injury in a Patient With Rotator Cuff Arthropathy.

Scapular fractures are uncommon, and the spine of the scapula is a particularly rare site of injury. As a result, our knowledge of these injuries, the management options and the functional outcome is limited. We report a rare case of a scapular spine fracture in a patient with rotator cuff arthropathy with no obvious history of trauma.

Imaging inflammation and its resolution in health and disease: current status, clinical needs, challenges, and opportunities.

Inflammation is a normal process in our body; acute inflammation acts to suppress infections and support wound healing. Chronic inflammation likely leads to a wide range of diseases, including cancer. Tools to locate and monitor inflammation are critical for developing effective interventions to arrest inflammation and promote its resolution.

Acromioclavicular joint disruptions: A comparison of two surgical approaches 'hook' and 'rope'.

Introduction: Acromioclavicular joint injuries are common shoulder girdle injuries most commonly resulting from a direct blow to the acromion with the arm adducted. Type-I or type-II acromioclavicular joint injuries can be managed with sling immobilization, early shoulder motion, and physiotherapy. The management of type-III injuries remains controversial and is individualized.

Automatic detection of tweets reporting cases of influenza like illnesses in Australia.

Early detection of disease outbreaks is critical for disease spread control and management. In this work we investigate the suitability of statistical machine learning approaches to automatically detect Twitter messages (tweets) that are likely to report cases of possible influenza like illnesses (ILI). Empirical results obtained on a large set of tweets originating from the state of Victoria, Australia, in a 3.

Plate on plate osteosynthesis for the treatment of nonhealed periplate fractures.

Purpose. The purpose of this paper is to present our technique for the treatment of periplate fractures. Methods.

Ruptured Baker's cyst with compartment syndrome: an extremely unusual complication.

A 69-year-old man presented with sudden onset of pain with acute tense swelling of his left leg. Initially he was treated empirically with antibiotics for cellulitis while the possibility of deep vein thrombosis was ruled out. His symptoms gradually worsened with progressive distal neurological deficit and increasing pain.

Transarticular shear fractures of the distal humerus.

Background: Capitellar fractures result from shearing and wedging forces transmitted to the elbow that create complex injury patterns that are difficult to stabilize. The fracture often extends into the trochlea and is associated with posterior comminution of the humerus and soft tissue injury. Diverse fixation techniques are required to restore the anatomy perfectly to ensure elbow function is regained.

Early results for treatment of three- and four-part fractures of the proximal humerus using the PHILOS plate system.

Secure fixation of displaced proximal fractures of the humerus is a challenging problem. A total of 32 patients with acutely displaced three- or four-part proximal fractures of the humerus were treated by open reduction and internal fixation using the proximal humeral internal locking system (PHILOS) plate. There were 23 women and nine men with a mean age of 59.

Tol2 transposon-mediated transgenesis in Xenopus tropicalis.

The diploid frog Xenopus tropicalis is becoming a powerful developmental genetic model system. Sequencing of the X. tropicalis genome is nearing completion and several labs are embarking on mutagenesis screens.

Pseudoaneurysm of profunda femoris artery following intertrochanteric fracture of the hip.

The authors report a case of pseudoaneurysm of the profunda femoris artery following fixation of an intertrochanteric hip fracture with a dynamic hip screw. Diagnosis and treatment of this rare complication are described.

Comparison of oxygenated perfluorocarbon and humidified oxygen for rewarming hypothermic miniswine.

This study examines a method to rapidly rewarm the core using total liquid ventilation with warmed, oxygenated perfluorocarbon. Yucatan miniswine were splenectomized and surgically implanted with telemetry devices to transmit electrocardiographic response, arterial pressure, and core temperature. Hypothermia (core temperature = 25.

Slipped capital femoral epiphysis: early mechanical damage to the acetabular cartilage by a prominent femoral metaphysis.

On the basis of intraoperative observations in 13 consecutive adolescents (14 hips) with slipped capital femoral epiphysis (SCFE), we found that when the anterior femoral metaphysis was level with or extended past the epiphysis, it caused labrum and cartilage damage. As a result of an impingement between the metaphysis and the superomedial acetabular rim, the labrum revealed erosions, scars or tears. Further jamming of the metaphysis into the joint damaged the adjacent acetabular cartilage, varying from a partial- to a full-thickness cartilage loss.

Influence of boot-sock systems on frequency and severity of foot blisters.

This study examined the infleunce of three types of boot-sock systems on incidence and severity of foot blisters. Participants were 357 men undergoing U.S.

Displaced bucket handle tears of the medial meniscus masking anterior cruciate deficiency.

Traditionally, anterior cruciate ligament (ACL) injuries have been difficult to diagnose in the Casualty Department. Studies have shown that the anterior drawer test has a poor sensitivity both in acute and chronic ACL deficient knees [4, 6, 9]; thus, more emphasis has been placed on the pivot shift and Lachman tests [3]. We report four cases of proven ACL rupture where clinical examination revealed an absent pivot shift and a near normal Lachman test following a displaced bucket handle tear of the medial meniscus.

Efficacy of antiperspirants on feet.

Nineteen male soldiers participated in a study of the effectiveness of two antiperspirants (aluminum chlorohydrate and aluminum zirconium tetrachlorohydrex glycine) in reducing foot-sweat accumulation and injuries. Each subject was tested before and after antiperspirant application, with a 1-hour treadmill march at 5.6 km/hour in a warm environment.

Cooling to heat of fusion (HOF), followed by rapid rewarming, does not reduce the integrity of microvascular corrosion casts.

This study utilized microvascular corrosion casting techniques to evaluate changes in the microvascular patency of rat hindpaws cooled to four different subzero temperatures. Left hindpaws of anesthetized rats in group 1 were cooled to -5 degrees C, in group 2 to -15 degrees C, in group 3 to heat of fusion (HOF), and in group 4 to HOF and then to -15 degrees C. Although freezing did not take place in the hindpaws of groups 1 and 2, initiation of freezing in the tissues, as indicated by HOF, did occur in groups 3 and 4.
