[Routine Practice Data for Evaluating Intervention Effects: Part 2 of the Manual].

The evaluation of intervention effects is an important domain of health services research. The ad hoc commission for the use of routine practice data of the German Network for Health Services Research (DNVF) therefore provides this second part of its manual focusing on the use of routine practice data for the evaluation of intervention effects. First, we discuss definition issues and the importance of contextual factors.

[Agenesis of the left lung in combination with a persistent left superior vena cava and al cor triatriatum sinister in a 77 year old man].

We report the case of a 77 year old man, who was hospitalized in the final stadium of his congenital disease. Following a pneumonia in the right lung the respirator therapy was needed. Later the patient died by a chronic right heart failure.

[Struma as a cause of a brachialgia].

A 76-year-old woman with a great multi-nodular goitre and no neurological deficits suffered from increasing pain of the lateral upper arm. A combination of nerve blockades and physical measures was not effective in terms of continuous pain control. Subtotal thyroidectomy resulted in a long-term complete pain relief.

[External synovial fistula of the infrapatellar bursa following arthroscopic meniscus resection. A clinical case report and topographic-anatomic study].

Following arthroscopic meniscectomy a 41-year old patient developed an external synovial fistula in the area of the central joint approach with a communication to the deep intrapatellar bursa. Anatomical preparations performed on 20 knee joints revealed extraordinary variations in the dimension of the infrapatellar bursa with a mean longitudinal diameter of 24 mm and a transversal diameter of 38 mm. The distance between bursa and the distal margin of the patella measured 15 to 39 mm.

Follow-up results of 3,500 arthroscopic operations on the knee joint.

In a clinical study the postoperative results of 3,500 arthroscopic operations on the knee joint were analyzed with a follow-up period of 1 year. At the time of examination 55.3% of patients were symptom-free, 33.

[Diseases of the shoulder joint from the orthopedic viewpoint].

The cardinal symptom in all shoulder disorders is shoulder pain. We have to differentiate between genuine shoulder pain originating from the glenohumeral joint and its periarticular structures and referred pain originating at a site distant from the shoulder joint, e.g.
