Purpose: The purposes of this study were to compare the magnitude and phase between the RR interval and QT interval variability in the frequency domain. METHODS: Twenty four, 12-13 year old healthy males were randomly selected. At resting state and for 5 minutes, ECGs were obtained, and they were digitized to 1000Hz. After measurement of RR interval, QT interval variability was measured using template matching strategy. After normalization of the RR and QT interval time series, power spectral and cross spectral analysis were performed. From each of the time series, low- (0.04-0.15 hertz) and high- (0.15-0.4 hertz) frequency power were measured. From the phase spectrum, the phases and time lags between the two time series at each of the two frequency range were calculated. RESULTS: The average of RR interval and QT interval was 616.0+/-71.0, 364.0+/-47.0 msec, respectively. Their normalized low- and high- frequency power was 4.4+/-7.9 NU(normalized unit), 0.1+/-0.1 NU(p<0.005), and 11.0+/-30.0 NU, 0.3+/-0.3(NU, p<0.005), respectively. The phase differences and resulting time lags between the two interval were -0.5+/-0.4 pi radian(-0.9 seconds) and -0.2+/-0.3 pi radian(-0.4 seconds) in the low- and high-frequency range, respectively. CONCLUSION: During resting state, when compared to RR interval, QT interval oscillates in significantly lower amplitude in both low- and high- frequency ranges. However, the oscillations precede those of the RR interval 0.9 seconds and 0.4 seconds, respectively.

We have evaluated the onset time and frequency of allergic reactions after topical application of tetracaine cream. Tetracaine cream was prepared on the antecubital area of forearm in 21 voluteers and antiinflammatory cream was applied also on same side forearm under an impermeable occlusive patch dressing. The mean anesthetic onset time of tetracaine site was 24.90+/-7.47 minutes and significant allergic reactions were not found. The ideal percutaneous local anesthetic formulation should have a comparatively low-concetration of drugs and provide a rapid onset of action combined with a deep and relatively prolonged anesthesia of the skin surface, in addition to underlying tissue. Although EMLA cream has been available, it requires a minimum application period of 1 hour using 2.5 g of preparation in combination with an occlusive dressing. The result of this study indicate that 4% tetracaine in carbomer base and in addition with sodium bicarbonate (Imeq/g) provided more rapid onset and prolonged anesthesia without any significant allergic reactions. So, we advise this 4% tetracaine cream for epicutaneous procedures (tattooing, removal of warts or senile ketatitis), venipuncture and venous cannulations, especially in children.

Anomalous right coronary artery arising from the left sinus of Valsalva is rare, but not protected from ather-osclerotic disease. Major factor determining successful angioplasty is the selection of the appropriate guiding catheter to provide optimal coaxial backup support. We report the first case of successful transradial stenting of an anomalous right coronary artery originating from the left sinus of Valsalva.

Background:
In the treatment of esophageal cancer, a gastric conduit is typically the first choice. However, when the stomach is not a viable option, the usual alternative is a colon conduit. This study compared the long-term surgical outcomes of gastric and colon conduits over the same interval and aimed to identify factors influencing the prognosis.
Methods:
A retrospective review was conducted of patients who underwent esophagectomy followed by reconstruction for primary esophageal cancer between January 2006 and December 2020.
Results:
The study included 1,545 patients, with a gastric conduit used for 1,429 (92.5%) and a colon conduit for 116 (7.5%). Using propensity-matched analysis, 116 patients were selected from each group for comparison. No significant difference was observed in longterm survival between the gastric and colon conduit groups, irrespective of anastomosis level and pathological stage. A higher proportion of patients in the colon conduit group experienced postoperative complications compared to the gastric conduit group (57.8% vs. 25%, p<0.001). Multivariable analysis revealed that age over 65 years, body mass index below 22.0 kg/m 2 , neoadjuvant therapy, postoperative anastomotic leakage, and renal failure were risk factors for overall survival in patients with a colon conduit. Regarding conduit-related complications, cervical anastomosis was the only significant risk factor among those with a colon conduit.
Conclusion
Despite the association of colon conduits with high morbidity rates relative to gastric conduits, the long-term outcomes of colon conduits were acceptable. More consideration should be given perioperatively to the use of a colon conduit, particularly in cases involving cervical anastomosis.
