The purposes of this study were to verify and compare the performances of anaerobic threshold (AT) point estimates among different filtering intervals (9, 15, 20, 25, 30 s) and to investigate the interrelationships of AT point estimates obtained by ventilatory threshold (VT) and muscle fatigue thresholds using electromyographic (EMG) activity during incremental exercise on a cycle ergometer. 69 untrained male university students, yet pursuing regular exercise voluntarily participated in this study. The incremental exercise protocol was applied with a consistent stepwise increase in power output of 20 watts per minute until exhaustion. AT point was also estimated in the same manner using V-slope program with gas exchange parameters. In general, the estimated values of AT point-time computed by EMG method were more consistent across 5 filtering intervals and demonstrated higher correlations among themselves when compared with those values obtained by VT method. The results found in the present study suggest that the EMG signals could be used as an alternative or a new option in estimating AT point. Also the proposed computing procedure implemented in Matlab for the analysis of EMG signals appeared to be valid and reliable as it produced nearly identical values and high correlations with VT estimates.

We report the case of a successful vaginal delivery following laparoscopic abdominal wall reconstruction in an adult survivor of an omphalocele without prior surgical repair. Untreated omphaloceles are rare in adulthood. A 30-year-old female patient presented with a large anterior abdominal wall defect due to an untreated omphalocele, who expressed a desire to have a baby in the near future. A laparoscopic herniorrhaphy was performed with a double-layered expanded polytetrafluoroethylene (ePTFE, Gore-Tex) mesh. The patient delivered a full-term healthy baby vaginally 2 years after surgical repair of the omphalocele.
