BACKGROUND AND OBJECTIVES Increased life expectancy makes increasingly older patients to be submitted to cardiac surgeries. This study aimed at evaluating the incidence of octogenarian patients submitted to cardiac surgeries in the Heart Institute, Hospital das Clínicas, FMUSP, in the last 16 years. METHODS The number of myocardial revascularization (MR) and valvar surgeries (VS) was analyzed...

PURPOSE To describe the incidence, risk factors, clinical presentation, causative organisms, and outcomes in patients with endophthalmitis following pars plana vitrectomy (20G and minimally invasive vitrectomy surgery (MIVS). METHODS Of 111,876 vitrectomies (70,585 20-G 41,291 MIVS) performed, 45 cases developed acute-onset, postoperative endophthalmitis. RESULTS The rate of culture positiv...

In an earlier paper, we used the absolute grading on Heegaard Floer homology HF to give restrictions on knots in S which admit lens space surgeries. The aim of the present article is to exhibit stronger restrictions on such knots, arising from knot Floer homology. One consequence is that all the non-zero coefficients of the Alexander polynomial of such a knot are ±1. This information in turn ca...

Two Dehn surgeries on a knot are called cosmetic if they yield homeomorphic manifolds. For a null-homologous knot with certain conditions on the Thurston norm of the ambient manifold, if the knot admits cosmetic surgeries, then the surgery coefficients are equal up to sign.

OBJECTIVE To determine differences in antibiotic prescription rates between conventional General Practice (GP) surgeries and GP surgeries employing general practitioners (GPs) additionally trained in integrative medicine (IM) or complementary and alternative medicine (CAM) (referred to as IM GPs) working within National Health Service (NHS) England. DESIGN Retrospective study on antibiotic pr...

OBJECTIVE Colon cancer patients presented with obstruction were known to have worse postoperative morbidity and mortality rates, but conflicting data has been reported in recent years. We aimed to investigate postoperative complication rates, and short and long-term oncological outcomes in patients with colon cancer treated with either emergency surgery due to obstruction or elective surgery. ...

The ever-increasing demands for surgeries and the limited resources force hospitals to have efficient management of resources, especially the expensive ones like operating rooms (ORs). Scheduling surgeries including sequencing them, assigning resources to them and determining their start times is a complicated task for hospital managers. Surgery referrals usually include elective surgeries that...

OBJECTIVE Estimate cataract surgical rates (CSR) for Brazil and each federal unit in 2006 and 2007 based on the number of surgeries performed by the Unified Health System to help plan a comprehensive ophthalmology network in order to eliminate cataract blindness in compliance with the target set by the World Health Organization (WHO) of 3,000 cataract surgeries per million inhabitants per year....

OBJECTIVES To evaluate the current needs for joint surgery in patients with psoriatic arthritis (PsA). METHODS The patient database at the Rheumatology Department of the University Hospitals Leuven, was cross-sectionally analysed using demographic, medical, laboratory, radiological and surgical data of 269 patients with PsA. Patients were grouped by the presence or absence of orthopaedic surg...
