[The thoracoscopic talc pleurodesis with intraoperative pleural biopsy - a retrospective analysis in patients with malignant pleural effusion]

The thoracoscopic pleurodesis with talc is an established therapy in case of malignant pleural effusion. With the instillation of talc a -localised inflammation is induced. However, some-times it turns into a severe systemic reaction. In this study of the postoperative course, the -question is examined whether a pleural biopsy is an additional risk factor for morbidity and mortality after talc pleurodesis.

A case of Maffucci syndrome

The Maffucci syndrome consists of a combination of multiple enchondromas and haemangiomas. It appears in the first two decades of life, with no family history. In this case we are reporting about a 26-year-old female who had suffered from multiple enchondromas since the age of two. At the age of nine, the patient presented with additional haemangiomas, which facilitated making proper diagnosis. She now presents with a massive lesion of her left upper extremity. The patient had initially rejected operative treatment when the disease was at early stages. At later stages, a more complex reconstruction of the hand would have been necessary to secure hand function. This procedure that sometimes induces a risk related to potential necessity of blood transfusion was rejected by the patient for religious reasons. Amputation of the extremity was therefore the last resort procedure.

An accuracy approach to robotic microsurgery in the ear

Concerns of rising healthcare costs and the ever increasing desire to improve surgical outcome have motivated the development of a new robotic assisted surgical procedure for the implantation of artificial hearing devices (AHDs). This paper describes our efforts to enable minimally invasive, cost effective surgery for the implantation of AHDs. We approach this problem with a fundamental goal to reduce errors from every component of the surgical workflow from imaging and trajectory planning to patient tracking and robot development. These efforts were successful in reducing overall system error to a previously unattained level.
