05). After IVIG treatment, the KD patients had lower Hb and segment levels but higher platelet, lymphocyte, and eosinophil levels than the EV patients (p < 0.05). In the KD patients, the platelet, eosinophil, and monocyte levels increased
after IVIG treatment, whereas Hb, WBC, and segment levels decreased significantly (p < 0.001). In the EV patients, eosinophil levels increased after IVIG treatment, whereas WBC BI 2536 price and Hb levels decreased significantly (p < 0.05). The study results provide evidence that eosinophilia may be related to IVIG therapy in KD and EV patients. The KD patients had higher eosinophil levels both before and after IVIG therapy than the EV patients, which may have been due to the inflammatory mechanism of KD. The KD patients had higher platelet levels than the EV patients, suggesting that platelets are involved in the inflammatory response to KD.”
“Perforation of the atretic pulmonary valve with balloon dilation in infants with pulmonary atresia with intact ventricular septum (PA-IVS) is standard
initial therapy for right-ventricular (RV) decompression. This procedure often results in adequate pulmonary blood flow, thus eliminating the need for PR-171 neonatal surgery. Nonetheless, the incidence of RV outflow-tract complications and mortality for this intervention is significant. We report our experience with retrograde snare-guided radiofrequency (RF) perforation in an attempt to improve accuracy and decrease procedural complications. Medical records were reviewed for the period between March 2007 and May 2010 for all patients with PA-IVS who presented to the catheterization laboratory for attempted RF perforation in infancy. Specific details reviewed included demographics, preprocedural echocardiographic (echo) data, procedural technique and complications, pre- and post-RV YM155 molecular weight pressures and pulmonary valve gradients, need for surgical intervention in the neonatal period,
and short- to medium-term follow-up. Eleven neonates with PA-IVS underwent RF perforation using a retrograde snare-guided technique during the study period. The pulmonary valve was successfully perforated and the wire snared in all 11 patients. Six of 11 atretic valves were crossed on the first attempt with low energy (5 W x 2 s). No episodes of tamponade or RV/PA perforation occurred as confirmed by echocardiogram performed immediately after the procedure. There was no ductal spasm with retrograde catheter manipulations. Sequential dilation of the perforated valve was not necessary. RV pressures decreased from 169 % systemic before dilation to 93 % after dilation (p < 0.001) with a residual pulmonary valve gradient of 16 +/- A 6 mm Hg. Eight of 11 patients (73 %) were discharged without surgery at an average 16 days after the intervention. Three patients required Blalock-Taussig shunts to augment pulmonary blood flow.
