[Gallbladder cancer as unexpected histologic diagnosis following cholecystectomy for cholelithiasis and cholecystitis].

Uncharacteristic symptoms, inadequate early diagnosis, and high malignancy are the major reasons why most of the patients with carcinoma of gallbladder are not admitted for clinical examination until metastasation had begun to involve the liver. So, the majority of authors who have made contributions to the literature are in agreement to the effect that the prognosis is extremely poor for patients with gallbladder carcinoma and that curative therapy is possible only in rare cases. There are only few reports on cases on whom operations could be performed in good time. Curable gallbladder carcinoma is more often than not an absolutely accidental finding obtained in the course of surgical treatment for cholelithiasis. Reported in this paper are four cases in which malignant lesions to mucosa were accidentally discovered by pathologists in histological examination of specimens obtained from cholecystectomy for cholecystolithiasis and cholecystitis. Problems involved in therapeutic action are discussed.

[Development of habitual shoulder dislocation].

The starting point of the retrospective analysis of 177 primary dislocations was the question of frequency of habitual dislocations, the correlation between habitual dislocation and time of early immobilisation, as well as the search for additional statements which would result in a differentiated therapy. 18.1% habitual dislocations were seen to develop, mostly after immobilisation for less than three weeks. It is an interesting fact that the technique of immobilisation made no difference. We found that after the first even there was generally no loss in function, whereas 14.5% of the men and 34.3% of the women complained of severe subjective symptoms. The 12 patients who underwent an operation because of habitual dislocation suffered neither from dysfunction nor from painful movement, and no dislocation was found. The rate of habitual dislocation in our patients showed a lower rate of dislocation of the shoulder joint. We found 18.1% dislocations, whereas the literature showed an average quota of 30%. To improve the results we recommend a special X-ray technique following the first reposition. In the age group between 20 and 30 years, which is most susceptible, we also recommend arthrography and arthroscopy of the shoulder joint. To improve typical lesions, such as osseous rupture of the capsule or what is known as Hill-Sachs lesions, primary operation is discussed as an alternative treatment.

[Osteosynthesis in the area of the hand. 168 cases of single and combination osteosyntheses].

In the years 1970-76 we have performed 168 cases of AO (ASIF) internal fixation of closed and compound fractures of the hand. The study gives a classification of fractures. The indications were as follows: Where closed manipulation did not give accurate reduction; where fragment dislocation was imminent and where malalignment of the fragments is already manifest. We also confirmed the value of internal fixation on compound fractures with associated injuries of nerves, vessels and tendons. A survey of our results is given using different methods and AO materials (screws, screwed plates, and combined methods) with or without K-wires for internal fixation, applied to different types of fractures in the hand. We also describe the preoperative preparation of the patient, the methods of anaesthesia, the follow-up treatment and the salutary effects of therapy on a mainly out patient basis.
