Three-dimensional accuracy of guided implant placement: indirect assessment of clinical outcomes.

Purpose: Precise preoperative implant planning and its exact intraoperative transfer are crucial for successful implant-supported rehabilitation of partially or completely edentulous patients. In the present pilot study, optical laser scanning was used to evaluate deviations between three-dimensional computer-assisted planned and actual implant positions by indirect methods.

Material And Methods: Five patients receiving a total of 15 implants were included in this study.

Microsporidiosis in travel-associated chronic diarrhea in immune-competent patients.

We analyzed retrospectively 21 immune-competent travelers with chronic traveler's diarrhea (3-6 weeks) after returning from recreational travel to the tropics with stool samples positive for microsporidia. Nine patients had been treated with albendazole and 12 patients had been treated symptomatically. Diarrhea resolved in 8 of 9 and 12 of 12 patients, respectively.
