Intraoperative three-dimensional ultrasonography: an approach to register brain shift using multidimensional image processing.

Neuronavigation uses the skull as a reference system for transfer of image-space data to physical space during brain surgery. This requires a stable spatial relation between the skull and intracranial structures. However, especially dura opening and preparation for lesion removal causes brain shift.

[Metronidazole and neomycin in wound infection prophylaxis in colon and rectal surgery].

Anaerobes (e.g. Bacteroides) are more important in postoperation wound infections due to surgical operations of the large intestine than expected in the past.

[Wound infection prophylaxis in colonic and rectal surgery with metronidazole and neomycin--a prospective study].

In a prospective study the authors report on their experience with preoperative bowel preparation using Metronidazole and Neomycin in combination with a low residue diet and orthograde cleaning of the bowel. They observed (elective surgery) wound infections in only 10%. Before this regimen was introduced the rate of wound infection came up to a percentage of 45.

[Malignant melanomas of fingers and toes (author's transl)].

From 1968 to 1978 more than 500 patients suffering from histologically verified malignant melanoma were seen. Only in 12 cases (appr. 2%) the tumour was situated on the tip of the fingers and toes.

[Bleeding complications after lung surgery (author's transl)].

Bleeding complications after lung resection are mostly due to surgical causes, seldom to coagulation disorders. Own experiences in 8 cases (= 0,59% of all lung operations) are reported. The early rethoracotomy prevents additional coagulation disorders which may arise following large infusions of plasmaexpanders and blood.
