BACKGROUND: Post tubercular constrictive pericarditis is prevalent pericardial disease in developing countries. Pericardiectomy is the treatment of choice but considered a procedure of high morbidity and mortality. METHODS: From January 2003 to December 2013 we performed 130 pericardiectomies. Mean age was 22.95±12.55 years with 92 (71%) males. All patients were symptomatic; 118 (91%) were in NYHA class III / IV. Almost all patients were diagnosed to be of tubercular origin; 14 (11 %) histopathologically proven, 77 (59%) with definitive history while 39 (30%) suspected to be of tubercular origin and 91 (70%) received prior antitubercular treatment...

Anatomical variants of muscle are commonly encountered by surgeons and radiologists. The flexor carpi radialis brevis (FCRB) is an anomalous muscle in the distal forearm with an estimated prevalence of 2-8%. In the literature, there are a few case reports of symptomatic FCRB tenosynovitis without a concomitant tear, and treatment methods described include both conservative and surgical management. We present a case of one patient with radial sided wrist pain and a partial FCRB tear, which to our knowledge is the first case report of a symptomatic FCRB tear...

Birds, particularly raptors, are believed to forage primarily using visual cues. However, raptor foraging tactics are highly diverse - from chasing mobile prey to scavenging - which may reflect adaptations of their visual systems. To investigate this, we studied the visual field configuration of 15 species of diurnal Accipitriformes that differ in such tactics, first focusing on the binocular field and blind area by using a single traits approach, and then exploring the shape of the binocular field with morphometric approaches...

BACKGROUND AND PURPOSE: Major League Soccer (MLS) has aggressively expanded from 10 teams to 23 teams. With the addition of more teams, the league will have to dictate a schedule that maximizes the league's popularity, while also maintaining the health of the players. A longer season and congested game schedule could increase the risk of injury for players. The purpose of this commentary is to make recommendations for the prevention of injuries among MLS players with respect to proposed league expansion...

For a long time, the phenomenon known as the "tears of wine" was believed to be due only to the surface tension gradient (e.g., the Thomson-Marangoni stress on the fluid/fluid surface's dynamics of wetting) and gravity. We experimentally demonstrated that the wine tear formation is not solely due to the surface tension gradient; instead, the ridge instability triggers the wine tears. Pouring wine into a glass causes a wine film to form on the glass. The film drains down under gravity and a ridge forms at its upper part...

The history of osteoarthritis (OA) is important because it can help broaden our perspective on past and present controversies. The naming of OA, beginning with Heberden's nodes, is itself a fascinating story. According to Albert Hoffa, R. Llewellyn Jones and Archibald Edward Garrod, the name OA was introduced in the mid-19th century by surgeon Richard von Volkmann who distinguished it from rheumatoid arthritis and gout. Others preferred the terms 'chronical rheumatism', 'senile arthritis', 'hypertrophic arthritis' or 'arthritis deformans'...

It is still unknown whether glenoid inclination or lateral acromial roof extension is a more important determinant for development of rotator cuff tears (RCT) or osteoarthritis (OA) of the shoulder. It was the purpose of this study, to evaluate whether there is a potential predominance of one of these factors in pathogenesis of RCT or concentric OA. We analyzed 70 shoulders with advanced degenerative RCT and 54 shoulders with concentric OA undergoing primary shoulder arthroplasty (anatomical or reverse) using antero-posterior radiography and multiplanar computed tomography...

Accurate and reliable monitoring of blood glucose is needed for the treatment of diabetes, which has many challenges, including lack of patient compliance. Measuring tear glucose is an alternative to traditional finger-stick tests used to track blood sugar levels, but glucose sensing using tears has yet to be achieved. We report a methodology for possible tear glucose monitoring using glucose-sensitive silicone hydrogel (SiHG) contact lenses, the primary type of lenses available in today's market. Initially, we assessed the interpenetrating polymer network, with nearly pure silicone and water regions, existing in the SiHGs using a polarity-sensitive probe Prodan...

Herein, we report on the preparation of novel cellulose-PEG biohybrid papers with wet strength properties. The biohybrid paper sheets are obtained using a two-step procedure where ω- or α, ω-azide functionalized PEG chains are anchored onto alkyne-functionalized wood fibers through CuAAC ligation in mild and aqueous conditions. The incorporation of the PEG grafts mostly occurs at the periphery of the cellulose fibers and degrees of substitution up to 0.028 are obtained. The presence of PEG grafts significantly increases the tensile, burst and tear strength properties in the wet state, the reinforcement being more pronounced for fibers grafted with α,ω-azide PEG...

Prior studies have not found significant differences in meniscal parameters between patients with meniscal and ligamentous injury and those without. The purpose of this study was to determine whether such relationships exist. Clinical records and magnetic resonance images of three subject groups were reviewed. Group 1 solely had meniscal tears (medial/lateral), Group 2 had meniscal tears with concurrent ACL tears, and Group 3 had healthy knees. The mean age of subjects included was 35.9 years (range 8.2-72...

BACKGROUND: Chronic subdural hematoma (CSDH) is one of the more frequent pathological entities in daily neurosurgical practice. Historically, CSDH was considered a progressive, recurrent bleeding with a traumatic etiology. However, recent evidence suggests a complex intertwined pathway of inflammation, angiogenesis, local coagulopathy, recurrent microbleeds and exudates. The aim of the present review is to collect existing data on pathophysiology of CSDH in order to direct further research questions aiming to optimize treatment for the individual patient...
