BACKGROUND Primary prevention of acute rheumatic fever requires antibiotic treatment of acute streptococcal pharyngitis. In developing countries, clinicians must rely on clinical guidelines for presumptive treatment of streptococcal pharyngitis since bacterial culture and rapid diagnostic tests are not feasible. We evaluated the WHO Acute Respiratory Infection guideline in a large urban paediat...

We attempt to quantify the widely-held believe that large hierarchies induced by stronglywarped geometries are common in the string theory landscape. To this end, we focus on the arguably best-understood subset of vacua – type IIB Calabi-Yau orientifolds with non-perturbative Kähler stabilization and a SUSY-breaking uplift (the KKLT setup). Within this framework, vacua with a realistically smal...

We exhibit bound states in the spectrum of non-compact D-branes in N = 2 Liouville conformal field theory. We interpret these states in the study of D-branes in the near-horizon limit of Neveu-Schwarz five-branes spread on a topologically trivial circle. We match semiclassical di-electric and repulsion effects with exact conformal field theory results and describe the fate of D-branes hitting N...

A test employing three fluorogenic 4-methylumbelliferyl substrates and the lectin of Dolichos biflorus was developed for the identification of beta-hemolytic streptococcal colonies associated with throat cultures. This non-serological method is unique in that it permits the accurate identification of groups C, F, and G streptococci, as well as groups A and B streptococci. The method is rapid, s...

We present a scenario where brane inflation arises more generically. We start with D3 and anti-D3-branes at the infrared ends of two different throats. This setup is a natural consequence of the assumption that in the beginning we have a multi-throat string compactification with many wandering anti-D3branes. A long period of inflation is triggered when D3-branes slowly exit the highly warped in...

Evidence-Based Answer Compared with placebo, antibiotics can shorten the duration of sore throat symptoms by about 16 hours and can reduce complications. In countries where the absolute rates of complications are higher, antibiotic therapy is more likely to be effective. The effectiveness of antibiotic therapy is greatest in persons with streptococcal pharyngitis. (Strength of Recommendation: A...

We analyse the dynamics of a probe D3-(anti-)brane propagating in a warped string compactification, making use of the Dirac-Born-Infeld action approximation. We also examine the time dependent expansion of such moving branes from the “mirage cosmology” perspective, where cosmology is induced by the brane motion in the background spacetime. A range of physically interesting backgrounds are consi...

INTRODUCTION Postoperative sore throat is a common complaint in patients with endotracheal intubation and has potentially dangerous complications. This randomized controlled trial study investigated the incidence of postoperative sore throat after general anesthesia when betamethasone gel is applied to a tracheal tube compared with when IV dexamethasone is prescribed. MATERIALS AND METHODS Tw...

OBJECTIVE To investigate whether or not Neisseria meningitidis was present in the throat of Kuwaiti pilgrims after returning from the Hajj. METHOD Throat swabs were taken from 177 participants 1 week after returning from the Hajj. The participants were asked about: associated medical conditions, meningococcal vaccination status and the intake of ciprofloxacin before leaving Mecca for Kuwait. ...
