The extraction of three implanted (18-, 16-, and ten year-old) damaged nonfunctional leads was complicated by a lead breaking and losing its external silicone tube. The missing part of the lead was invisible on X-ray, but was visible in ECHO as a thin, corded, very mobile limp structure without metallic reflection. Incomplete lead extraction did not cease laboratory symptoms of infection. The l...

introduction: transplantation of bone marrow stromal cells (bmscs) or schwann cells (scs) can increase axonal regeneration in peripheral nerve injuries. based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury . we pursued to evaluate the effects of bmscs and scs co-transplant...

To locate the proximal and distal cut ends of the canaliculus following trauma is the most difficult part of canalicular repair, especially in patients with complex acute canalicular lacerations and late presenting canalicular lacerations. Previously, irrigation and air-injection technique are reported and widely used to locate the cut ends of lacerated canaliculus. However, we have developed a...

The role of silicone intubation in routine dacryocystorhinostomy (DCR) surgery remains unclear. Recent studies provide a higher level of evidence against intubation in DCR. Intubation of the nasolacrimal duct with silicone tubes has largely arisen as a result of history, anecdote and the evolution of DCR surgery rather than being based upon sound evidence. Silicone intubation has gained popular...

PURPOSE To describe the CT and MR characteristics of intraocular silicone oil (polydimethylsiloxane), which is used with increasing frequency to treat complicated retinal detachments. METHODS CT was performed on a silicone oil/water phantom and on a patient with retinal detachments secondary to cytomegalovirus retinitis, treated by bilateral intraocular injections of silicone oil. CT appearan...

BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the outcomes of surgical management in fistulous dacryocystitis cases associated with nasolacrimal duct (NLD) obstruction. MATERIALS AND METHODS Twenty-two patients (14 female, 8 male) with fistulous dacryocystitis were included. The patients were divided into two groups as congenital (Group I) and acquired (Group II) groups. Fis...

The general-purpose laryngeal mask airway (LMA) is re-usable when undamaged, and cleaned and autoclaved correctly. We had found weakening of the silicone adhesive that bonds the connector of the LMA to the tube. We report that repeated autoclaving damaged the adhesive such that the connector could be rotated in the tube after the 12th autoclave cycle in almost all of the LMA tested. The damage ...

Introduction. Adhesive tapes are used for taping eyelids closed and securing endotracheal tubes during general anesthesia. These tapes can cause facial skin injury. We compared the incidence of facial skin injury and patient satisfaction with different tapes used. Methods. A total of 60 adult patients at risk of skin trauma were randomized to use 3M™ Kind Removal Silicone Tape or standard acryl...
