A six-year study of hydroxyapatite-coated root-form dental implants.

BACKGROUND: The effect of hydroxyapatite coating of dental implants is controversial. The long-term fate of hydroxyapatite-coated implants has been the subject of some criticism. PURPOSE: The aim of this retrospective study was to assess the clinical outcome of hydroxyapatite-coated cylindrical root-form endosseous Impladent dental implants (LASAK Ltd, Prague, Czech Republic) during a six-year course. METHODS: Three-hundred and ninety-one consecutively placed implants were used in 169 patients and followed for four to six years. Interval and cumulative success of implants and prostheses survival was tabulated. Marginal bone loss was measured RESULTS: Of the total number of implants, 98.5% achieved initial osseointegration. The cumulative success was 98.3% after one year, 97.0% after three years, 92.8% after five years and 90.4% after six years. The prostheses survival at the end of the study was 100% for fixed bridges totally supported by implants, 96.5% for fixed bridges with combined implant and tooth support, 94.2% for single crowns, 90.9% for mandibular overdentures and 81.3% for maxillary overdentures. Marginal bone loss averaged 2.4 +/- 0.8 mm at the end of five years. CONCLUSION: The success rate of the investigated hydroxyapatite-coated implants was comparable with the data presented in the literature and with the results of the similar implants without hydroxyapatite-coating. However, the marginal bone loss was of interest. Longer monitoring of the implants is necessary.

The use of oxidized regenerated cellulose (surgicel) in closing Schneiderian membrane tears during the sinus lift procedure.

During the sinus lift procedure, undesirable perforations of the Schneiderian membrane can occur in up to 58% of cases. Several methods for their closing exist. This article presents a method of covering the perforation with a strip of oxidized regenerated cellulose (Surgicel). One or two layers of material swell after being saturated with blood, turning into a gelatinous mass and forming a tight and mechanically resistant seal. This simple method has been successfully tested on 223 perforations of the Schneiderian membrane that occurred over a period of 58 months.

Tumors of the rectum and anus.

Within a ten year period we have performed 433 radical operations on the rectum. An anterior resection of rectum was done in 110 cases, low anterior resection in 60 patients, very low anterior resection was done by stapler in 32 patients and was sewn by hand in 10 patients. Colo-anal anastomoses were performed 86 times and abdominoperineal amputation of rectum sec. Miles 20 times. Local transsphincteric procedures were used 14 times. In 12 patients the colo-anal anastomosis was performed either for recurrence of tumor or after a Hartmann's procedure. In the carcinoma of the lower half of the rectum there is still an unsolved question: whether to perform a low or a very deep low anastomosis or whether an extirpation of rectum with sparing the sphincters and sewing a colo-anal anastomosis is more beneficial. In the years 1980-1995 we treated surgically 64 patients with a tumor in anal area. All patient underwent preoperative radio- and chemotherapy. In our group adenocarcinoma was demonstrated in 6 patients, squamous carcinoma in 48 patients and squamous cells of the carcinoma in situ in 10 patients.

[Laparoscopy in abdominal injuries].

Application of laparoscopy in trauma was studied in Traumatological Hospital in Brno, within a more widely concipated project of grant IGA, Ministry of Health in Czech Republic. In the series of 28 patients there was detected neither a single complication, nor a reoperation nor any significant damage to the patient in connection with the use of the endoscopic method detected. Results of the research and author's observations act as a guide for use of more precise indication criteria and adequate selection of patients and for the proper evaluation of the method. Provided that basic principles and priorities of the urgencies management are kept, the application of this minimally invasive method in the management of patients with selected both the blunt and the penetrating abdominal trauma is justified, including associated extraabdominal injuries and polytrauma. It's diagnostic contribution exceeds the therapeutic one.

[Laparoscopic inguinal hernioplasty--results in the initial group 2 years after surgery].

The authors evaluate retrospectively after a two-year interval the results of laparoscopic inguinal hernioplasty (L.I.H.) in an initial group of 49 patients (52 hernias) operated by three surgeons using the method of transabdominal preperitoneal plastic operation (TAPP) in 1993, 1994 and 1995. They confirmed the expected favourable results, except for the very high incidence of relapses (6.7%). In view of the small number of patients other conclusions cannot be drawn except analyse the three early failures of L.I.H., indicate technical mistakes made when introducing the new operation and emphasize the necessity to adhere to the known basic technical details when performing this relatively pretentious laparoscopic operation.

[Injuries of organs in the abdominal and retroperitoneal cavities].

In the Traumatological Hospital Brno approx. 100 polytraumatised patients yearly are admitted with involvement of 2, 3 or 4 systems. During the period of years 1982-1991 authors operated 308 injured patients with increasing haemoperitoneum, 254 patients with profuse bleeding into retroperitoneum, 77 patients with traumatic perforative peritonitis and 61 patients with severe thoracoabdominal trauma. Mortality in this group was 26%. Authors evaluate the contribution of new diagnostic methods for the indication of early surgical treatment, and results of operations, complications and problems.

[Trauma and emergency thoracoscopy].

Authors present their first experience with urgent videothoracoscopy in polytraumatism and in isolated thoracic trauma patients. During the prospective study in 1993-1995 thoracoscopically was treated 41 (18%) from 229 multiple trauma patients including thorax trauma, hospitalised in our Institute. Thoracoscopy underwent 62 (4%) from 1452 patients with simple thoracic trauma. Thoracoscopy has been indicated above all for continued bleeding into peritoneal cavity, for suspected diafragmatic injury and for the diagnosis and treatment of posttraumatic complications. Authors suggest that thoracoscopy is in experienced hands and adequatelly equipped workplaces an accurate and safe method for the diagnosis and in some cases also for therapy of hemodynamic stabile patients with thoracic trauma.
