Conventional GTG banding showed that the women in both couples had a 46,X,add(X)(p22) karyotype. Further molecular cytogenetic studies showed that both women had a 46,X,der(X)t(X;Y)(p22;q11.2) karyotype and that the affected boy had inherited the Ruboxistaurin derivative X chromosome, which resulted in an Xp contiguous gene syndrome. After an assessment of reproductive risk, the first couple conceived naturally and opted for prenatal diagnosis (PND) by amniocentesis. No abnormal karyotypes were found for the twin pregnancy and healthy twin girls were born after a full-term normal pregnancy. The second couple chose to undergo IVF with preimplantation

genetic diagnosis (PGD). Two PGD cycles were performed by fluorescence in-situ hybridization. In the first PGD cycle, all three embryos had abnormal hybridization

signals. In the second cycle, a male embryo with normal hybridization signals was transferred into the womb and a normal pregnancy was achieved. The results show the importance of detecting the derivative chromosome followed by PND or PGD if a woman carries an Xp;Yq translocation. (C) 2013, Reproductive Healthcare Ltd.

“Laparoscopy is an effective method of implantation for peritoneal dialysis (PD) catheters. Use of the laparoscopic technique is increasing because of its potential advantages over other techniques. In most patients, selection for PD is based on negative criteria, and because Selleck NSC-23766 of the need for general anesthesia, the laparoscopic technique can be life-threatening in these patients. On the other hand, local anesthesia is insufficient for laparoscopic catheter implantation. To avoid the need for general anesthesia and to achieve patient safety and satisfaction, we designed a type of conscious sedation (dissociative conscious sedation) and compared the efficacy of subcutaneous (SC) and intravenous (IV) ketamine see more added to narcotics in patients scheduled for laparoscopic implantation of a PD catheter.

Methods: Our prospective randomized double-blind

study enrolled 60 adult patients with chronic renal failure who were scheduled for laparoscopic implantation of a PD catheter. Patients were randomly assigned to one of two groups: one receiving IV ketamine, and the other receiving SC ketamine. In both groups, patients were premedicated with IV midazolam 0.015 mg/kg, fentanyl 1-2 mu g/kg, and lidocaine 1.5 mg/kg. Patients then received 0.6 mg/kg ketamine either intravenously (IV group) or by subcutaneous injection at the anterior aspect of the forearm (SC group). If systolic blood pressure (BP) increased more than 20% from baseline or exceeded 170 mmHg, IV nitroglycerine (TNG) 50 mu g was administered incrementally (repeated 50-mu g doses). After a desirable level of conscious sedation was achieved, local anesthesia and nitrous oxide pneumoperitoneum were applied, and the PD catheter was implanted under laparoscopic guidance. Heart rate and BP were measured throughout the procedure.
