Résumé
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.
Résumé
Persistent Müllerian duct syndrome (PMDS) is a rare form of male pseudohermaphroditism characterized by the presence of the Mόllerian duct structures in an otherwise phenotypically as well as genotypically normal male. We report a case of 40-year-old cryptorchid male who was clinically diagnosed as seminoma in the undescended abdominal testis. A diagnosis of PMDS was made on histological evaluation subsequent to abdominal orchidectomy.
Résumé
Infrared spectra of normal and malignant breast tissues were measured in the 600 cm(-1) to 4000 cm(-1) region. The measured spectroscopic features which are the spectroscopic fingerprints of the tissues contain the vital information about the malignant and normal tissues. Fourier Transform Infrared (FTIR) data on 25 cases of infiterating ductal carcinoma of breast with different grades of malignancy from patients of different age groups were analyzed. The samples were taken from the tumor sections of the tissue removed during surgery. Infrared spectra demonstrate significant spectral differences between the normal and the cancerous breast tissues. In particular changes in frequency and intensity in the spectra of protein, nucleic acid and glycogen vibrational modes as well as the band intensity ratios for lipid/proteins, protein/nucleic acids, protein/glycogen were observed. This allows to make a qualitative and semi quantitative evaluation of the changes in proliferation activity from normal to diseased tissue. It was evident that the sample to sample or patient to patient variations were small and the spectral differences between normal and diseased tissues were reproducible. The findings establish a framework for additional studies, which may enable us to establish a relation of the diseased state with its infrared spectra.
