Distal humeral plating of an intramedullary nail periprosthetic fracture using a miss-a-nail technique: a case report

The treatment of distal humeral periprosthetic fractures is not widely described in the literature. We present a difficult clinical scenario of a 72-year-old man who sustained a displaced distal humeral periprosthetic fracture about a Polarus Plus intramedullary nail. In this case, stable fixation was achieved using bicondylar Acumed Mayo congruent Plates using a miss-a-nail technique. Four months following the post operative period, the patient regained satisfactory range of movement with full function and no further complications up to 18 months post fixation. Treatment of such complex periprosthetic fractures is technically achievable and with potentially good results

Synthesis of Single-Phase Anatase TiO2 Nanoparticles by Hydrothermal Treatment

Pure anatase powders of titanium dioxide with a homogeneous nanosized particles distribution were prepared by a facile hydrothermal route using solution of acetic acid and tetraisopropyl orthotitanate as the precursors with a molar ratio of 1:1. The modified hydrolyzed alkoxide was treated at various temperatures under different autogenic pressures. Two different reactors were employed as autoclaves for heating and generation of high pressures during the synthesis and crystallization of TiO2 nanoparticles. The characteristics of TiO2 powders obtained under various synthesis conditions were verified using X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FE-SEM). The results indicated that particles size of the formed TiO2 could be finely tuned by varying the experimental parameters of temperature, pressure and the amount of nitric acid in the peptization step. TiO2 nanoparticles with good dispersion and mean size of about 9 nm could be seen in FE-SEM image of sample synthesized under temperature of 160 °C for 12 h using more nitric acid in the peptization step.

Experimental two dimensional cellular flames

International audienceThe propagation of very unstable cellular flames (also called self-turbulent flames) is studied experimentally in a Hele-Shaw cell. This quasi-two dimensional configuration allows for quantitative image analysis. The dynamics of the premixed flame is controlled in these conditions by the creation or merging of the cusps that appear on the front

Systemic thrombolysis with tenecteplase in stent thrombosis patients as a life saving measure in odd situations: an observational study from tertiary care hospital

Background: Coronary artery stent thrombosis specifically acute stent thrombosis is always a nightmare for interventionist. Stent thrombosis is one of a severe and catastrophic complication of percutaneous coronary intervention (PCI). Repeat PCI is commonly considered the preferred strategy to manage patients with stent thrombosis. Thrombolytic therapy is considered only partially effective.Methods: This was a single centre largest ever observational study on this topic comprising of total 110 patients with history of previous stent implantation and now presented with an acute ST segment elevation myocardial infarction due to a probable stent thrombosis successfully treated with systemic thrombolysis with tenecteplase were studied over the period of 2 years (April 2017 to March 2019).Results: On analyzing data clinical success was reported in 92 (83.6%) patients, electrocardiographic success is seen in 102 (92.7%) patients while angiographic success was reported in 80(72.7%) patients. Cerebrovascular accident were reported in 2 (1.8%) patients which died later on.Conclusions: This study which is the first ever largest observational study on this topic demonstrates that, in patients with probable stent thrombosis and a short time to reperfusion in some specific extraordinary situations where timely percutaneous coronary intervention is not possible, systemic thrombolysis by fibrin specific Tenecteplase can be done as a life saving procedure which is associated with good immediate results
