- Purpose: To evaluate the manometric effects of three different swallow maneuvers on healthy volunteers. Material and Methods: Ten healthy volunteers with no history of swallowing complaints were evaluated with simultaneous videoradiography and pharyngeal manometry (videomanometry). Three different swallow maneuvers were evaluated (supraglottic swallow, super-supraglottic swallow, and Mendelsohn's maneuver) and seven manometric and two videoradiographic variables were analyzed. Results: The supraglottic swallow showed a significantly weaker peak contraction of the upper esophageal sphincter (UES). The super-supraglottic swallow had a significantly higher UES relaxation pressure and the Mendelsohn maneuver a significantly higher UES peak contraction. With the Mendelsohn maneuver, there was also a significantly longer duration of the pharyngeal contraction and a significantly weaker UES peak contraction. Both the super-supraglottic and the Mendelsohn maneuver had a significantly longer bolus transit time. Conclusion: Our study did not show any significant difference in the relaxation duration of any of the swallowing maneuvers compared to a control swallow. With the Mendelsohn maneuver, we found that both the pharyngeal peak contraction and contraction duration were increased, which might result in an improved propulsion of bolus into the esophagus.

- P>The coordination of swallowing and respiration is essential for a safe swallow. Swallowing consists of several subsecond events. To study this, it is important to use modalities with high temporal resolution. In this study, we have examined young healthy individuals with simultaneous videofluoroscopy, videomanometry and respiratory recording, all with high temporal resolution. The onset of 13 predetermined swallowing and respiratory events and the surrounding respiratory phase pattern were studied in different body positions and during different respiratory drives. An increased respiratory drive was induced by breathing 5% CO2. The results demonstrated a highly repeatable and fixed temporal coordination of the swallowing pattern despite body position and respiratory drive. Previous studies have demonstrated a period of centrally controlled apnoea during swallowing. This apnoea period has a variable length, varying from 1 to 5 s. During increased respiratory drive, we could demonstrate a significantly shorter period of apnoea during swallowing, mainly due to an earlier resumption of respiration. The high temporal recordings in this study have revealed that swallowing during expiration is present basically in all healthy individuals. This swallowing respiratory pattern seems to be appropriate for a safe swallow. This knowledge will be used as a reference for future studies on how swallowing and respiratory coordination might be altered due to ageing and diseases.

- Background: Painful forefoot deformity from rheumatoid arthritis can be treated with resection of the lesser metatarsal heads combined with either resection or arthrodesis of the first metatarsophalangeal (MTP) joint. Methods: In a prospective, randomized study we compared arthrodesis of first MTP joint with Mayo resection as part of total forefoot reconstruction in patients with painful forefoot deformity from rheumatoid arthritis. The lesser metatarsal heads were resected and extensor tenotomy was done in all patients. Thirty-one patients were randomized to either the arthrodesis or resection group. Results: After a mean followup of 36 (26 to 52) months, the median subjective satisfaction score was 96 points out of 100 in the resection group and 92 points in the arthrodesis group. Significant improvements in pain, handicap, and activity according to Foot Function Index (FFI) were found in both groups ( p < 0.001 except for handicap in resection group and activity in fusion group were p = 0.02). There were no statistically significant differences between the groups in these measures, nor in the patients' willingness to have the procedure again. There were no recurrences of prominences or tenderness under the forefoot in either group and no recurrence of severe hallux valgus in the resection group. The arthrodeses healed in 93%. There was no higher risk for clinically relevant IP joint symptoms after arthrodesis. The operating time was significantly longer in the arthrodesis group but this was not linked to a higher wound infection rate. Conclusion: These results indicate that Mayo resection may still be a good choice for the first MTP joint in total forefoot reconstruction in patients with rheumatoid arthritis.
