Utilization of the validated Psoriasis Epidemiology Screening Tool to identify signs and symptoms of psoriatic arthritis among those with psoriasis: a cross-sectional analysis from the US-based Corrona Psoriasis Registry.

BACKGROUND: Despite increasing awareness of the disease, rates of undiagnosed psoriatic arthritis (PsA) are high in patients with psoriasis (PsO). The validated Psoriasis Epidemiology Screening Tool (PEST) is a five-item questionnaire developed to help identify PsA at an early stage. OBJECTIVES: To assess the risk of possible undiagnosed PsA among patients with PsO and characterize patients based on PEST scores. METHODS: This study included all patients enrolled in the Corrona PsO Registry with data on all five PEST questions. Demographics, clinical characteristics and patient-reported outcomes were compared in Corrona PsO Registry patients with PEST scores ≥3 and <3 using t-tests for continuous variables and chi-squared tests for categorical variables; scores ≥3 may indicate PsA. RESULTS: Of 1516 patients with PsO, 904 did not have dermatologist-reported PsA; 112 of these 904 patients (12.4%) scored ≥3 and were significantly older, female, less likely to be working, and had higher BMI than patients with scores <3. They also had significantly longer PsO duration, were more likely to have nail PsO and had worse health status, pain, fatigue, Dermatology Life Quality Index and activity impairment. CONCLUSIONS: Improved PsA screening is needed in patients with PsO because the validated PEST identified over one-tenth of registry patients who were not noted to have PsA as having scores ≥3, who could have had undiagnosed PsA. Appropriate, earlier care is important because these patients were more likely to have nail PsO, worse health-related quality of life and worse activity impairment.

Recognizing occupational illnesses and injuries.

Given the burden of occupational illnesses and injuries in the United States, family physicians should understand the role workplace exposures may play in patients' chief concerns. Incorporating employment screening questions into patients' intake questionnaires is an efficient means of identifying potential occupational causes of symptoms. Recommended questions include what kind of job patients have; whether their symptoms are worse at work; whether they are or have been exposed to dust, fumes, chemicals, radiation, or loud noise; and whether they think their health problems may be related to their work. These questions are especially important when the diagnosis or etiology is in doubt. Depending on patients' responses to the screening questions, a more detailed occupational history may be appropriate. It can be useful to ask about routine tasks performed during a typical work shift, as well as anything out of the ordinary (e.g., a change in routine, an injury or accident). The occupational history should include information about alcohol and tobacco use, second or part-time jobs, military service, hobbies, and home environment. Patients with suspected occupational illnesses or injuries may benefit from referral to an occupational medicine specialist for a more detailed assessment and follow-up.

A Portable Sensory Augmentation Device for Balance Rehabilitation Using Fingertip Skin Stretch Feedback.

Neurological disorders are the leading causes of poor balance. Previous studies have shown that biofeedback can compensate for weak or missing sensory information in people with sensory deficits. These biofeedback inputs can be easily recognized and converted into proper information by the central nervous system (CNS), which integrates the appropriate sensorimotor information and stabilizes the human posture. In this study, we proposed a form of cutaneous feedback which stretches the fingertip pad with a rotational contactor, so-called skin stretch. Skin stretch at a fingertip pad can be simply perceived and its small contact area makes it favored for small wearable devices. Taking advantage of skin stretch feedback, we developed a portable sensory augmentation device (SAD) for rehabilitation of balance. SAD was designed to provide postural sway information through additional skin stretch feedback. To demonstrate the feasibility of the SAD, quiet standing on a force plate was evaluated while sensory deficits were simulated. Fifteen healthy young adults were asked to stand quietly under six sensory conditions: three levels of sensory deficits (normal, visual deficit, and visual + vestibular deficits) combined with and without augmented sensation provided by SAD. The results showed that augmented sensation via skin stretch feedback helped subjects correct their posture and balance, especially as the deficit level of sensory feedback increased. These findings demonstrate the potential use of skin stretch feedback in balance rehabilitation.

Separating deployment-related traumatic brain injury and posttraumatic stress disorder in veterans: preliminary findings from the Veterans Affairs traumatic brain injury screening program.

OBJECTIVE: Traumatic brain injury in returning Iraq and Afghanistan combat veterans has been the subject of numerous articles by the popular press and congressional inquires. Recent research has questioned the accuracy of the traumatic brain injury diagnosis in veterans with depression and/or posttraumatic stress disorder and the validity of the Veterans Affairs traumatic brain injury screening tool to identify traumatic brain injury in returning combat veterans. DESIGN: Medical records of all combat veterans in the Veterans Affairs Connecticut Healthcare System who both screened positive for traumatic brain injury and received clinical evaluation for traumatic brain injury during the first year of the Veterans Affairs traumatic brain injury screening program were reviewed to explore the relationship between posttraumatic stress disorder and self-reported symptoms attributed to deployment-related traumatic brain injury. RESULTS: Ninety-four combat veterans identified from positive traumatic brain injury screens were seen in the Veterans Affairs Connecticut Healthcare System from April 1, 2007, to March 30, 2008. Eighty-five percent of the veterans with positive screens met the American Congress of Rehabilitation Medicine definition of probable traumatic brain injury. Symptom reporting was similar for veterans with and without a history of traumatic brain injury. Veterans with both posttraumatic stress disorder and traumatic brain injury were more likely to report falling as a mechanism of injury and indicated that they had suffered a head injury during deployment (P

Physiologic variations of the internal jugular vein surface, role of the omohyoid muscle, a preliminary echographic study.

The action of the omohyoid muscle on the hemodynamics of the internal jugular vein is controversial. For some authors, contraction of this muscle, by tightening the cervical fascia, promotes jugular venous return. For others, contraction of this muscle compresses the jugular vein in its cervical path. With this latter point in mind, the hemodynamics of the internal jugular vein have been studied in its cervical path by echography in 10 healthy volunteers. One hundred twenty measurements of the venous surface were made at rest, with the mouth open and during deep inspiration. In the last 2 situations, evidence of a significant increase in the venous surface was found above the omohyoid muscle. These data confirm the role of compression of the vein by the omohyoid muscle, leading to modifications in intracerebral venous hemodynamics, which can be affected in yawning.
