Community-acquired methicillin-resistant Staphylococcus aureus pneumonia in a children's hospital. Our ten-year experience.

Introduction: Community-acquired methicillinresistant Staphylococcus aureus (CA-MRSA) infections have increased in recent years. CAMRSA necrotizing pneumonia and empyema are now more common in children.

Objectives: To determine the prevalence of CA-MRSA pneumonia and its clinical and epidemiological characteristics compared to Streptococcus pneumoniae (SP) pneumonia in the same population.

[Clinical- epidemiological characteristics and predictors of coronary complications in children of Argentina with Kawasaki disease].

Background: Kawasaki disease (EK) is an acute systemic vasculitis with a risk of developing coronary aneurysms.

Aim: To describe the clinical and epidemiological characteristics of children with EK in Argentina and to analyse the risk factors for the development of coronary's complications (CC).

Methods: Multicenter, retrospective, cross-sectional, observational and analytical study.

Halide-Controlled Extending-Shrinking Motion of a Covalent Cage.

Herein, we present an example of covalent cages, whose flexible framework undergoes extending-shrinking motion under halide control. In the absence of halide anions, the free cage assumes a flattened conformation: the cavity is compressed along the C axis passing through the tertiary amines, and the two tribenzylamine platforms are eclipsed. Halide encapsulation promotes a large conformational rearrangement of the cage, involving an extension of the cavity along the C axis and shrinkage along the equatorial plane.

Community-acquired methicillin-resistant Staphylococcus aureus infections: 10-years' experience in a children's hospital in the city of Rosario, Argentina.

Introduction: Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are a common reason for consultation in pediatrics. Most of them present as skin and soft tissue infections; however, invasive infections have increased during the last decade.

Objectives: The main objective was to describe the clinical-epidemiological characteristics of CA-MRSA infections.

Supramolecular Anion Recognition Mediates One-Pot Synthesis of 3-Amino-[1,2,4]-triazolo Pyridines from Thiosemicarbazides.

A facile one-pot synthesis of 3-amino-[1,2,4]-triazolo[4,3-a]pyridines from thiosemicarbazides through anion mediated synthesis is reported. Thiosemicarbazides derived from 2-hydrazino pyridine, 5-chloro 2-hydrazino pyridine, and 2-hydrazine quinoline were formed in situ as anion receptors in the presence of TBAF. Under microwave heating, thiosemicarbazides furnished the triazolo pyridines in good to moderate yields.
