[Outcome after craniocerebral gunshot injury].

Gunshot wounds to the head have a high morbidity and mortality [1, 2, 3, 4, 5]. In our areas this kind of injury is rarely seen, being mostly due to attempted suicide [6]. To help determine the optimal management of patients with penetrating GSW to the head, retrospective experience with 47 patients from 1986 to 1993 is presented. Due to our experiences we provide the following treatment of patients with craniocerebral gunshot wounds: After a short neurological examination and the stabilization of the vital parameters, we do further examination with skull X-ray and a CT. With these informations we decide about the further treatment: We operate patients with stable vital signs, with GCS higher than 3, as long the ventricular system is not involved. 18 patients survived the injury. The currently living 16 patients were examined and checked concerning outcome after GSW to the head. 11 of 16 patients had a GOS 4 or 5. The remaining 5 patients are dependent on permanent help.

[Computer-assisted production and evaluation of surgical reports with FileMaker Pro 2.0].

A software application based on FileMaker Pro 2.0 from Claris is presented. Three files have been created: the first file "Operationen" contains all data required to write operation reports. By entering the ICD-9 code (VESKA code), the application imports and shows the text of the operation title according to the ICD-9 code from the second file "VESKA-TH". This makes data entering and control easy and convenient. By changing layouts, different preformatted reports are ready to be printed. The third file "OP Auswertung" creates different reports and summaries, sorted by ICD-9 code or other criteria, such as surgeon, institution or type of anaesthesia. Our experience with 3970 operation reports showed that this application is easy to learn, has a good compliance and saves a lot of time writing or analysing operation reports. It can be used with Macintosh or Windows.

Quantitative evaluations of gap junctions in old rat brown adipose tissue after cold acclimation: a freeze-fracture and ultra-structural study.

The morphological and functional modifications of brown adipose tissue (BAT), the tissue responsible for non-shivering thermogenesis, are well established during the phases of active stimulation (i.e. neonatal period and cold acclimation) in young animals. The 'active' brown adipocytes are filled with numerous small lipid vacuoles and large mitochondria packed with cristae rich in the protonophore uncoupling protein (UCP), whereas the 'quiescent' cell shows larger, confluent vacuoles and smaller mitochondria with rarefied cristae poor of the uncoupling protein. It is well known from literature that also gap junctions (gjs), responsible for the electrical coupling among adjacent adipocytes, modify their size following the physiological stimulus in young animals. This is in agreement with the morphology of the functionally active brown adipocyte, i.e. the multilocular, UCP-positive cell. Although the presence of the BAT in old animals is well documented, less is known about its reactivity to physiological stimuli. The present work demonstrates that after cold acclimation brown adipocytes of old rats (2 years) change their ultrastructure in a similar way as in young rats. A quantitative analysis of gap junction areas on replicas obtained by the freeze fracture technique, showed that gj increase in size (mean area 53.2 vs 110.4 x 10(-3) microns2, p = 0.003). All these morphological modifications are quite similar to those observed in BAT of young and young adult rats, supporting the hypothesis of a physiological role of brown adipose tissue at every age.

Preoperative diagnosis of Meckel's diverticulum by pertechnetate scan and laparoscopic resection.

Acute lower gastrointestinal hemorrhage in a 17-year-old boy was caused by a Meckel's diverticulum 1 day after ingestion of 500 mg acetylsalicylic acid. After conservative treatment of the bleeding, the diverticulum was diagnosed in the free interval by technetium pertechnetate scintigraphy, which showed an accumulation in the right lower quadrant simultaneously with the accumulation in the gastric mucosa. Elective explorative laparoscopy confirmed the diverticulum, and the resection was performed by laparoscopic means. Histology showed gastric-type mucosa in the diverticulum. The treatment of choice for Meckel's diverticulum, when it is diagnosed preoperatively or during laparoscopy, is laparoscopic resection.

[Management of patient data in an intensive care unit with Macintosh and Filemaker Pro--extra effort or facilitation of routine care with improved information flow?].

A documentation system for patients in ICU is presented. The programming is based on Filemaker Pro from Claris. Two files have been created: the first "1 Eintritt" contains all the patients data like name, address, the patients history, diagnosis, therapies as the planned procedures. All these data can be imported into the second file "2 KG Unfallchirurgie" with a personal identification number. Complications, new results or further procedures can be added. Different layouts allow the user to print summaries or duty reports. The experience with 300 patients showed, that this system is easy to learn and to use, that it has a good compliance with the medical staff and that is gains a lot of time writing summaries or reports used for transferring patients to other units.
