The distal radial approach (DRA) is suggested to have benefits over the conventional radial approach (CRA) in terms of local complications and comfort of both patient and operator. Therefore, we aimed to compare the feasibility and safety of DRA and CRA in a real life population. We conducted a prospective, observational multicentric trial, including all patients undergoing coronary procedures in September 2019. Patients with impalpable proximal or distal radial pulse were excluded. Thus, the choice of the approach is left to the operator discretion. The primary endpoints were cannulation failure and procedure failure. The secondary endpoints were time of puncture, local complications and radial occlusion assessed by Doppler performed one day after the procedure. We enrolled 177 patients divided into two groups: CRA (n = 95) and DRA (n = 82). Percutaneous intervention was achieved in 37% in CRA group and 34% in DRA group (p = 0.7). Cannulation time was not significantly different between the two sets (p = 0.16). Cannulation failure was significantly higher in DRA group (4.8% vs 2%, p < 0.0008). Successful catheterization was achieved in 98% for the CRA group and in 88% for the DRA group (p = 0.008). Radial artery occlusion, detected by ultrasonography, was found in 3 patients in the CRA group (3.1%) and nobody in the DRA group (p = 0.25). The median diameter of the radial artery diameter was higher in the DRA than the CRA group (2.2 mm vs 2.1 mm; p = 0.007). The distal radial approach is feasible and safe for coronary angiography and interventions, but needs a learning curve.

Ectopic molar pregnancy is a rare occurrence and consequently not often considered as a diagnostic possibility. We report two cases of molar hydatidiform tubal pregnancy. Diagnosis of ectopic pregnancy was confirmed on clinical biological and sonographic investigations. Diagnosis of molar pregnancy was done on histopathology. The clinical course was favorable for both patients. Although rare, molar changes can occur at any site of an ectopic pregnancy. Clinical diagnosis of a molar pregnancy is difficult but histopathology is the gold standard for diagnosis.

Whereas several studies have been made in the solid state on complexes between antimony(III) and bromide or iodide, only few complexes of antimony(III) chlorides with organic cations have been investigated. In these compounds the metal shows a tendency towards distorted octahedral coordination with some rather long Sb-Cl bonds, which is attributed to the crystalpacking forces, e.g. hydrogen bonds rather than by lone electron-pair repulsion. These compounds are interesting because they exhibit phase transitions (ferro-paraelectric) related to motions of the ammonium cations. Here, we describe the crystal structure of (4-dimethylaminopyridinium) tetrachloroanti monate(III).The complex crystals were obtained by dissolving in a concentrated HCl solution a stoichiometric mixture of 4-dimethylaminopyridine and trichloride antimony(III); the resulting aqueous solution was then kept at room temperature. After several weeks of evaporation, pseudohexagonal prismshaped monocrystals of (4-dimethylaminopyridinium)tetrachloroantimonate(III) appeared in the solution. Chemical analyses of antimony atoms and chloride anions were carried out. 5 The experimental conditions used for single-crystal data collections are reported in Table 1. The positional parameters for the antimony atoms were obtained from a three-dimensional Patterson map, while the remaining atoms were found from a successive difference Fourier map. After introducing anisotropic thermal displacement parameters for the non-hydrogen atoms, the hydrogen atoms were localized and optimized to fixed positions. Their contributions were isotropically introduced into the calculation, but not refined. The final atomic coordinates are given in Table S1 (supporting information).The final anisotropic full-matrix least squares resulted in a convergence of the R factor to 0.0316, incorporating the weighting scheme w = 1/[s 2 (Fo 2 ) + (0.0746P) 2 ] + 0.8242P], where P = (Fo 2 + 2Fc 2 )/3.The molecular structure of the (4-dimethylaminopyridinium)-tetrachoroantimonate is shown in Fig. 1. The crystal structure consists of 4-dimethylaminopyridinium cations and polynuclear anions in which distorted SbCl6 octahedron sharing cis edges are interconnected into chains (Fig. 2). The [SbCl4] -anions share two cis edges with two other neighboring octahedra, and a skew infinite chain is formed parallel to the c axis at x = 0, y = 0 and x = 0.5, y = 0.5. Each Sb atom is surrounded by six Cl atoms, forming a distorted octahedral configuration with Cl-Sb-Cl X-ray Structure Analysis Online Synthesis and Crystal Structure of (4-Dimethylaminopyridinium)-tetrachoroantimoniateAfef GHOUILI, Najla CHAARI, † and Fatma ZOUARI Laboratoire des Sciences des Matériaux et d'Environnement, Faculté des Sciences de Sfax, BP 802, 3018 Sfax, TunisiaThe salt tris(4-dimethylaminopyridinium)tetrachoroantimonate C7H11Cl4N2Sb crystallizes at room temperature in the monoclinic system with space group C2/c.
