Nine patients with rheumatoid arthritis, who had Silastic prostheses (Swanson's) introduced into 34 metacarpophalangeal joints, were reviewed 5 years after surgery. The most important long-term advantage conferred by the introduction of prostheses was pain relief; functional benefit was marginal. The majority of prostheses eventually fractured but this did not necessarily lead to a functional d...

In an earlier study (Ahmad, Haltmeyer & Eik-Nes, 1973), we reported maintenance of spermatogenesis in tubules of hypophysectomized rats adjoining intratesticular implants of silastic capsules containing testosterone or dihydrotestosterone (DHT). It was suggested that the local differences in the testes of the rats receiving the two treatments might be attributed to the relative amounts of hormo...

Four different experiments were performed to study the healing of a large, non-vascularised, diaphyseal, bone segment in adult cats. In the first experiment, a 4 cm segment of tibia with its periosteum was excised and replaced in its bed. The other experiments were similar, except that in the second, the periosteum of the segment was removed, in the third its medullary canal was blocked with a ...

BACKGROUND To the best of our knowledge this is the first case where a Silastic drain is used in ureteral surgery instead of a common urological stent. Patients coming from other institutions, especially in peripheral areas, can be treated with non conventional devices and if traditional imaging is inconclusive, computed tomography (CT) can provide valuable information to make the right diagnos...

PURPOSE To report the case of a silastic sheet that was found during an endoscopic transnasal dacryocystorhinostomy for treatment of acute dacryocystitis with necrosis of the lacrimal sac. METHODS A thirty-two year old male presented with painful swelling on the nasal side of his left lower lid two weeks prior to visiting this clinic. Fourteen years ago, the patient was involved in a traffic ...

OBJECTIVES To investigate whether the insertion of a Silastic sheet between the middle turbinate and lateral nasal wall can prevent lateral synechia formation when an unstable, floppy middle turbinate results from endoscopic sinus surgery (ESS). DESIGN Prospective study. SETTING University hospital. PATIENTS Thirty patients who developed an unstable, floppy middle turbinate during ESS wer...

The spontaneous rupture of a Silastic catheter is a rare occurrence. We describe our experience of managing a tiny premature infant with embolization of a Silastic percutaneous central venous catheter (PCVC) and discuss the possible mechanisms of the embolization. A 28-week, 980 g, preterm male infant received a Silastic PCVC (Epicutaneo Cava Catheter, Vygon, Germany) for parenteral nutritional...

UNLABELLED The development of implant dentistry improved the possibilities of rehabilitation with maxillofacial prosthesis. However, clinically it is difficult to bond the silicone to the attachment system. OBJECTIVES This study aimed to evaluate the effect of an adhesive system on the bond strength between acrylic resin and facial silicone. MATERIAL AND METHODS A total of 120 samples were ...
