(E)-4-Octyloxybenzaldehyde thio­semicarbazone

In the title compound, C16H25N3OS, the thio­semicarbazone group adopts an E configuration with respect to the C=N bond and is almost coplanar with the benzene ring, forming a dihedral angle of 9.3 (1)°. In the crystal packing, the mol­ecules lie along the a axis in an anti­parallel arrangement and are held in place by van der Waals inter­actions. As a consequence, there is relatively low anisotropic thermal motion in the terminal atoms of the n-octyl chain

2,4-Dimethoxy­benzaldehyde azine

The title mol­ecule, C18H20N2O4, is located on a crystallographic centre of symmetry. The meth­oxy groups are coplanar with the benzene ring [interplanar angles of 14.4 (2) and 3.1 (3)°], indicating a conjugation effect

Methyl 3-[(E,E)-3-phenyl­prop-2-enyl­idene]dithio­carbazate

In the title compound, C11H12N2S2, the dithio­carbazate group adopts an EE configuration with respect to the C=C and C=N bonds of the propenyl­idene group. The atoms of the propenyl­idene and dithio­carbazate unit are essentially co-planar, with a maximum deviation of 0.058 (1) Å; the phenyl ring forms a dihedral angle of 18.3 (1)° with this fragment. In the crystal, mol­ecules form inversion dimers via pairs of N—H⋯S hydrogen bonds involving the terminal S atom

(E)-4-(Benz­yloxy)benzaldehyde thio­semicarbazone

In the title compound, C15H15N3OS, the thio­semicarbazone group adopts an E configuration with respect to the C=N bond. The benzaldehyde thio­semicarbazone fragment is almost planar [maximum deviation = 0.012 (1) Å], while the dihedral angle between the benz­yloxy and phenyl rings is 72.48 (5)°. In the crystal structure, mol­ecules are inter­connected by N—H⋯N and N—H⋯S hydrogen bonds, forming a two-dimensional network parallel to the bc plane and are further stacked along the a axis by π–π inter­actions [centroid–centroid separation 3.9043 (7) Å]. The crystal structure is also stabilized by C—H⋯π inter­actions

Di-μ-methacrylato-κ4 O:O′-bis­[aqua­bis(1,10-phenanthroline-κ2 N,N′)copper(II)] dinitrate dihydrate

The title complex, [Cu2(C4H5O2)2(C12H8N2)2(H2O)2](NO3)2·2H2O, contains a dimeric [Cu2(C4H5O2)2(C12H8N2)2(H2O)2]2+ dication with two five-coordinated CuII ions linked by two methacrylate ions in a syn–syn bridging arrangement. The dication possesses pseudo-twofold rotational symmetry. The penta­coordination of each CuII ion has a distorted square-pyramidal geometry, with two N donors from a phenanthroline ligand and two carboxyl­ate O atoms occupying basal sites and the apical position being occupied by a water mol­ecule. In the crystal packing, mol­ecules are linked to form a three-dimensional framework by O—H⋯O and C—H⋯O hydrogen bonds and π–π inter­actions [centroid–centroid distances of 3.6039 (15), 3.5301 (15), 3.6015 (15), 3.6496 (15) and 3.6858 (15) Å]

An international survey on the pragmatic management of epistaxis

Epistaxis is one of the most common ear, nose and throat emergencies. The management of epistaxis has evolved significantly in recent years, including the use of nasal cautery and packs. However, a correct treatment requires the knowledge of nasal anatomy, potential risks, and complications of treatment. Epistaxis is often a simple and readily treatable condition, even though a significant bleed may have potentially severe consequences. At present, there are very few guidelines concerning this topic. The current Survey explored the pragmatic approach in managing epistaxis. A questionnaire, including 7 practical questions has been used. The current International Survey on epistaxis management reported a relevant prevalence (21.7%), mainly during childhood and senescence, an important hospitalization rate (11.8%), the common use of anterior packing and electrocoagulation, and the popular prescription of a vitamin supplement and intranasal creams
