An unusual shaped IUS.
A 45-year-old nulliparous woman attended for removal and replacement of a levonorgestrel-releasing intrauterine system (IUS) for continued management of dysmenorrhoea. I had placed the IUS some 6 years previously under a cervical block, needing to dilate the tight cervical canal for insertion. The patient’s periods had been well controlled. The IUS was easily removed but, as pictured, the arms ...
متن کاملResponse regarding an unusual shaped IUS.
I read with interest Dr MacGregor’s letter regarding the unusual shape of a Mirena intrauterine system (IUS) following removal. From the photograph it would appear that the capsule has become displaced and the arms of the device enclosed within it. We have seen a case of complete detachment of the capsule from the frame, with unrecognised retention of the capsule within the uterine cavity. This...
متن کاملInfluence of an Inclusion on Multi-Pass Copper Shaped-Wire Drawing by 2D Finite Element Analysis
The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...
متن کاملUnusual shaped IUS.
I read with interest Anne MacGregor’s letter in the January 2013 issue of the Journal describing the removal of an unusually shaped intrauterine system (IUS) and asking if others have had similar experiences. A couple of years ago I too was alarmed as I removed an IUS through a slightly tight cervical os and noted an odd shape. On closer inspection the device was removed intact, but as in Dr Ma...
متن کاملCrystal structure and thermochemical reactivity of an unusual copper complex that contains copper in four different coordination geometries.
According to X-ray single-crystal structure analysis, {[Cu(II)(en)2]2[Cu(I)2(CN)6]}[Cu(II)(en)2]2[Cu(I)(CN)3]2.2H2O contains copper in four different coordination environments: trigonal planar, square planar, square pyramidal and tetrahedral. The different coordination geometries of copper were investigated by quantum chemical calculations of model compounds, thus allowing to tentatively assign...
