The implantation process involves complex and synchronized molecular and cellular events between the uterus and the implanting embryo. These events are regulated by paracrine and autocrine factors. Trophoblast invasion and migration through the uterine wall is mediated by molecular and cellular interactions, controlled by the trophoblast and the maternal microenvironment. This review is focused...

Advanced technology or premium intraocular lenses have been developed to meet the patient expectations of perfect distance and near vision without the need for spectacles. Careful patient selection is critical when implanting these implants. This brief review focusses mainly on multifocal and toric IOLs and their application and limitations in patients with glaucoma. How to cite this article: I...

A 71-year-old female patient has a history of complete heart block and recurrent pacemaker site infection requiring multiple pacemaker explanations. A leadless pacemaker using passive fixation was inserted into the right ventricular apex via transvenous approach without complications. This case illustrates the feasibility of implanting a leadless pacemaker system in a small-sized adult with a l...

For cataract patients with extreme refractive errors, implanting 2 IOLs in 1 eye, piggyback style, provides an opportunity to treat the refractive error along with the cataract. The piggyback lens implantation strategy (Figure 15-1) can be used to treat high hyperopia,1-5 extremely high myopia,6 and high astigmatism (using toric lenses). In many cases, clear lens replacement with piggyback lens...

The practice of implanting foreign bodies into the penis for psychosexual reasons has been reported in journals of urology, radiology, and dermatology.'-4 It has not, to our knowledge, been reported in journals of venereology. Venereologists should be familiar with this practice, which may otherwise be mistaken for other pathological conditions. We here report three cases seen at this hospital ...

Three cases of erosion and extrusion of a pacemaker catheter with infection are reported. Treatment consisted of removing the infected catheter without delay and administering systemic antibiotics. Local antibiotics did not prevent septicemia and resultant death in one patient. Modiication of our original technique by employing the cephalic vein below the clavicle or implanting the catheter beh...
