Chrome congestive heart failure: Radiofrequency ablation of accessory pathways: implications of accumulated experience and time dedicated to procedures

Previous reports on radiofrequency ablation of accessory pathwayshave shown that the experience of the operator is of crucialimportance in reducing fluoroscopy time and achieving highersuccess rates. However, a detailed analysis of this importantissue has not been previously attempted We analysed 71 consecutive ablation procedures undertaken atSt George's Hospital by the same electrophysiology group andalways with the same first operator. Of all procedures, 66 (916%)were successful, as judged by abolition of accessory pathwayconduction without recurrence within the next 24 h. Failuresincluded two out of 38 left-sided pathway procedures (5·3%),one out of 11 intermediate septal (9·1%) and four outof 22 right-sided pathway procedures (18·2%). These differencewere not statistically significant. Average procedure and screeningtimes for all procedures were 162·9±86·0min and 56·8±48·2 mm respectively, whereasthe median of the number of discharges was 12, ranging fromone to 51. There was no significant difference between pathwaygroups or between concealed and non-concealed pathways in respectto procedure and screening time or number of discharges. Therewas a significant tendency towards decreased procedure and screeningtimes with accwnulating experience and this was similar forall pathway groups. There was also a tendency towards improvedcwnulative success rates with time dedicated to procedures. We conclude that a certain amount of ablation experience isrequired, even by experienced electrophysiologists, before arelatively high success rate without long radiation exposurecan be achieved, regardless of the location or the mode of conductionof the pathway. Success rates increase with procedure time,suggesting that early abandonment of the procedure may resultin higher failure rates in diffcult cases.     

Leucocyte populations in semen and male accessory gland function: relationship with antisperm antibodies and seminal quality

Semen samples from 279 infertility patients attending an Immunological Centre were analysed to evaluate the relationship between the populations of leucocytes, seminal quality, antisperm antibodies, and seminal vesicle function. The most frequent finding between leucocytospermic samples was asthenozoospermia (57%), whereas in non-leucocytospermic samples normozoospermia was the most frequent finding (47%). In the samples with asthenozoospermia, granulocytes predominated, whereas in those with oligozoospermia and azoospermia a reduction in the number of macrophages and lymphocytes was observed, suggesting an obstructive process at the level of epididymis and/or vas deferens where these leucocytes are mostly produced. In the case of hypofunction of the seminal vesicles there was a predominance in granulocytes. The increased levels of each type of leucocytes affected seminal quality only when seminal vesicles were affected. Only the elevated granulocytes count was related to a decrease in sperm motility. In those samples with leucocytospermia, positive antisperm antibodies (ASA) were associated with low sperm motility, low sperm normal morphology, and low value of seminal corrected fructose, whereas, in the absence of leucocytospermia, ASA, were more related to low sperm counts. These data suggest that granulocytes were more related to seminal vesicles dysfunction and sperm motility changes, and that ASA may be observed in the presence or absence of leucocytospermia.     

副神经移位膈神经后膈肌运动诱发电位与病理学对照研究

[目的]探讨副神经移位膈神经重建高位颈髓损伤大鼠呼吸功能后膈肌的病理学变化及膈肌运动诱发电位(motion evoked potential,MEP)的特点。[方法]健康雄性SD大鼠60只。随机分为1～6个月6个时间组。取下颈部正中切口,将双侧副神经在锁骨下水平发出内、外侧支之前切断,移位缝接膈神经干起始部。术后第1～6个月各组样本取颈后正中切口,切除C3全椎板充分显露颈髓并于C3、4水平锐性横断。证实胫前肌MEP完全消失后,于两侧腋前线肋下缘作切口,显露该处膈肌腹腔侧。直视下将同心针电极于腋前线第9肋骨下缘垂直胸壁插入膈肌肋部,监测其MEP的变化。然后完整取出膈肌,于电子天平称重。并于右侧腋前线顺膈肌肌纤维方向切取2 mm宽肌条行HE染色。分析膈肌肌纤维截面积的变化。[结果]神经移位后随着时间延长,大鼠膈肌MEP潜伏期逐渐缩短,波幅逐渐增大。6个月组MEP波幅为(6.35±0.51)mV,潜伏期为(3.41±0.36)m s。同时,膈肌逐渐饱满,肌重逐渐恢复,6个月为正常对照组的(97.23±4.07)%。肌纤维截面积也逐渐增大,6个月组达(1 741±439)μm2为正常对照组(1 809±461)μm2的(98.28±3.65)%。6个月组的各数据与对照组比无显著差异(P>0.05)。[结论]从电生理及病理学来看副神经可作为运动神经移位膈神经重建高位颈髓损伤后呼吸功能。

Clinical Recurrences After Successful Accessory Pathway Ablation:

Dormant Accessory Pathways. Introduction : Recurrence of clinical symptoms after radiofrequency catheter ablation of an accessory atrioventricular pathway (AP) may be due to the late manifestation of an additional AP that was not detected during the initial ablation session. It was the purpose of this study to elucidate the phenomenon of these "dormant" APs.
Methods and Results : Of 1280 consecutive patients who underwent radiofrequency catheter ablation of an AP, 54 patients (4.2 %) developed clinical symptoms postablation, necessitating a repeat ablation session. Recurrence of conduction over the AP targeted al the initial ablation session was found in 45 patients, whereas in the other 9 patients (0.7%) the manifestation of a previously unnoticed AP had caused symptom recurrence. Retrospective analysis of the data from these patients' ablation sessions revealed that the late manifesting AP was ablated at a site clearly different from that of the initially targeted AP, and that the manifestation of conduction over a previously "dormant" AP occurred significantly later than the recovery of a presumably ablated AP. Seven (78%) of the 9 "dormant" APs were concealed, and none exhibited decremental conduction properties.
Conclusion : The incidence of clinical recurrences mediated by the late manifestation of conduction over a previously "dormant" AP is low. The lack of an anatomic vicinity of these predominantly concealed APs with the initially targeted AP and the lack of evidence for their presence during the initial ablation session suggest intermittent conduction as the most likely explanation for their late manifestation.

Accessory Scrotum with Penoscrotal Transposition and Retrocerebellar Arachnoid Cyst: A Case Report

A 2-year-old boy presented with an accessory scrotum associated with penoscrotal transposition and a perineal lipoma. He also had a retrocerebellar arachnoid cyst. The accessory scrotum was resected with concurrent scrotoplasty. The retrocerebellar arachnoid cyst was seen on a subsequent brain computed tomography scan and was left untreated because there was no evidence that the volume was increasing.
