160. Schalenprothese für das Hüftgelenk nach Wagner DBGM

Zusammenfassung Der Film demonstriert am Beispiel eines Patienten mit Verschlußikterus durch Pankreaskopftumor das technische Vorgehen bei totaler Pankreatektomie, einschließlich präop. Diagnostik und postop. Nachbehandlung. Bei 30 konsekutiven Duodeno-Pankreatektomien der letzten 3 Jahre (16 davon totale Pankreatektomien) gab es weder eine Operations- noch Hospitalletalität.     

Acute pancreatitis after liver transplantation: incidence and contributing factors

In order to assess the incidence and possible predisposing and contributing factors in the development of acute pancreatitis after liver transplantation, we reviewed the medical records of all 1832 adult patients who underwent 2161 orthotopic liver transplantation (OLTx) procedures in our center between January 1987 and September 1992. Of these patients, 55 (3% incidence) developed clinical pancreatitis and 247 (13.4% incidence) developed hyperamylasemia (biochemical pancreatitis). Overall mortality in cases of clinical pancreatitis was 63.6%. The mortality in cases of hyperamylasemia was similar to that found in the general liver transplant population (i.e., 23%). A strong correlation was found between pancreatitis after liver transplantation and end-stage liver disease due to hepatitis B (30% of the cases, P=0.00001). Extensive surgical dissection around the pancreas (P<0.05), the type of biliary reconstruction following liver transplantation (P<0.05), and the number of liver grafts received by the same patient (P=0.00001) appeared to be possible contributing factors as did the duration of venovenous bypass and the quantity of IV calcium chloride administered intraoperatively.     

Oral function in patients treated with prostheses on Branemark osseointegrated implants in partially edentulous jaws: a pilot study

To study the oral function of partially edentulous patients treated with fixed prostheses on osseointegrated implants, recordings of the masticatory efficiency and occlusal perception of thickness were performed. The retrievable fixed partial prostheses were used to study the immediate impact of reduced fixed occlusal support on masticatory efficiency. The masticatory efficiency was subjectively satisfactory but objectively lower when compared to naturally complete dentate persons. Furthermore, the immediate impact of reduced fixed occlusal support was compromised masticatory efficiency, which was more pronounced when the occlusal support was removed on either side.     

The value of contrast sensitivity in diagnosing central serous chorioretinopathy

A 39‐year‐old hyperopic male was referred for laser refractive treatment. In the course of the pre‐operative evaluation he complained of a recent deterioration of vision. The suspicion of unilateral central serous chorioretinopathy (CSCR) was confirmed by contrast sensitivity testing and by ocular fundus examination. Contrast sensitivity (CS) for six spatial frequencies (1, 2, 4, 8, 12 and 16 c/deg) was evaluated using Gabor patches of gratings projected on a high‐resolution display by means of a stimulus generator card. Although VA remained unaltered, the pattern of contrast sensitivity function varied at different stages of CSCR: during the acute stage, performance at all spatial frequencies was depressed, while at two‐month follow up, intermediate and high spatial frequencies were mainly affected. It is concluded that the level of visual deficit in CSCR cannot be evaluated by measuring visual acuity. History and contrast sensitivity can play a central role in setting the correct diagnosis and characterising its stage.
