[Superinfected epidermal inclusion cyst of the thigh with development of squamous cell carcinoma--case report of a rare complication].

Epidermal cysts (atheroma) are the most common benign tumours of the skin with ubiquitous localisation all over the body. However, rupture of the atheroma and formation of an inclusion cyst with additional superinfections are frequently seen. Malignant transformations have rarely been reported.

[Are IT-based clinical pathways superior to hard-copy form?].

Background: Today clinical pathways are established as a basis for the operational and organisational structure of surgical, interventional and conservative treatments in many hospitals.

Question: In our study we have evaluated the establishment and systematic applicability of IT-based clinical pathways in the department of general surgery in comparison with existing clinical pathways. Does the systematic application of IT-based clinical pathways improve the quality of medical treatment?

Methods: In our department of general surgery we evaluated and compared the treatment by laparoscopic surgery before and after establishment of IT-based clinical pathways.

[Appendectomy with respect to flat fee and special rate charges. Cost analysis of open and laparoscopic operation].

The introduction of flat charges per case and special fees, first put into effect on Jan. 1, 1996, has lead medical and administrative personnel to rethink how fixed daily hospital rates, costs individually determined by each hospital, and prime costs for hospital and nursing charges will be reimbursed. The amount paid for flat charge cases and special fees (in German Marks) are currently the same nationwide.

[Diagnostic laparoscopy and laparoscopic appendectomy in the diagnosis and therapy concept of abdominal pain of unknown origin].

The unclear lower abdominal pain can be problematic for the surgeon although modern diagnostics and technical equipment are applied. We present the experiences in a retrospective study carried out in our hospital since beginning of laparoscopy in unclear lower abdominal pain. The laparoscopic diagnostic provides valuable additional informations for the further treatment.
