Endokrine Therapie des metastasierten Mammakarzinoms

One of the characteristics of breast cancer is its hormone dependency, which provides a number of effective approaches for treatment. Endocrine therapies usually have a good tolerability and oral application is convenient. Third generation aromatase inhibitors are well established in the treatment of metastatic breast cancer, having overtaken Tamoxifen. In the adjuvant setting, the ATAC trial is beginning to demonstrate the superiority of anastrozol compared to Tamoxifen. A new set of trials, coordinated by the International Breast Intervention Study Group, will compare the anti-hormones in healthy postmenopausal women with a moderate risk of developing breast cancer and in women after surgery for ductal carcinoma in situ. This article will discuss the various options for endocrine therapy in metastatic breast disease. The indications for endocrine manipulation as well as the various drugs will be discussed.     

Stellenwert der Rektoskopie und Koloskopie für den Internisten

The endoscopic examination of the large intestine can be considered today a routine examination in internal medicine. Since the introduction of flexible videoendoscopy, evaluating diseases in the distal colon using rectoscopy has become less important. Ano-proctoscopy is an obligatory component for a complete colon diagnostic after a flexible ileo-colonoscopy has been performed. Colonoscopy has improved significantly the diagnosis and therapy of diseases in the large intestine since it has been introduced more than 30 years ago. By introducing modern videocolonoscopy in addition to other instruments, there is today a broad spectrum of diagnostic and therapeutic indications available. Specifically, due to its frequency and prognostic relevance, colonoscopy has become the most powerful and important procedure in the early detection and prevention of colon cancer.     

Innovationen in der gynäkologischen Endoskopie

After the triumph of endoscopy in gynaecology, new developments can be seen more with the invention and optimisation of instruments than with the introduction of new surgical techniques. The endoscopic surgeon is very much dependent on sophisticated and precise instruments to perform high quality operations in an acceptable time. In hysteroscopy, optical systems have more and more been miniaturised with concomitant enhanced quality. A new and safe technique for hysteroscopic sterilisation has been developed and bipolar resectoscope systems have been created. In laparoscopy, optical systems, bipolar instruments, morcellators and a monopolar loop electrode have also been markedly improved. New modes of energy application such as the BiClamp technique and reusable ultrasound dissectors are helpful in improving the quality of coagulation and reduce operative time.     

Winkelstabile Plattenfixation

There are fundamental biomechanical differences between fixed-angle plate systems, also referred to as internal fixators, and conventional plate-screw fixation systems. Fixed-angle systems have rapidly gained widespread acceptance in recent years for almost all indications and anatomical sites. This contribution presents tips and tricks on their implantation and on the management of complications. Much of the information has already been presented elsewhere, in print or orally. Some of it is based on the authors’ own experience in their hospitals. The tips and tricks presented here are intended to help surgeons find pragmatic solutions to intraoperative problems.     

Posttraumatisches septisches Abdomen

Abdominal infection has the fifth highest incidence of all posttraumatic infections but has the second highest mortality rate with 25%,pneumonia,with 29%, being the only posttraumatic infection that is more frequently lethal.Posttraumatic abdominal sepsis, on the other hand, has a mortality rate of almost 50%.This rate cannot be reduced except by prompt identification of the correct diagnosis of the underlying injury or complication.This means that delayed laparotomy is strikingly detrimental in these patients, with 46% mortality as opposed to 11% in patients who undergo laparotomy promptly. In parallel with this, the mortality of fresh-onset and localized peritonitis is 14%,whereas that of diffuse purulent peritonitis is up to a devastating 42%.
