Can Preimplantation Genetic Diagnosis (PGD) be used for gender selection? | ['This testing is used for identifying singlegene disorders, chromosomal abnormalities, mitochondrial disorders, gender selection in non-mendelian disorders with unequal gender distribution, aneuploidy screening, and other preconceptually identified genetic abnormalities in prospective parents. ', ' Although many clinics offer PGD for HA by gender selection, an approach that detects the presence of the underlying F8 mutation has several advantages. ', 'Preimplantation genetic diagnosis (PGD) for gender selection for non-medical reasons has been considered an unethical procedure by several authors and agencies in the Western society on the basis that it could disrupt the sex ratio, that it discriminates against women and that it leads to disposal of normal embryos of the non-desired gender. In this study, the analysis of a large series of PGD procedures for gender selection from a wide geographical area in the USA shows that, in general, there is no deviation in preference towards any specific gender except for a preference of males in some ethnic populations of Chinese, Indian and Middle Eastern origin that represent a small percentage of the US population. ', ' In response to one specific question, one-third of the couples agreed to use the donor child as a lifetime organ donor and supported the use of PGD for non-medical gender selection. ', 'More specifically, I illustrate how the prescriptions of deliberative democracy can be applied to the issue of regulating non-medical uses of pre-implantation genetic diagnosis (PGD), such as gender selection. ', 'Private clinics were more likely than other programs to be on either the East or West Coast, list certain PGD risks (e.g., diagnostic error), note that PGD was new or controversial, reference source of PGD information, provide accuracy rates of genetic testing of embryos, and offer gender selection for social reasons.', 'The purpose of this article is to ascertain and appraise the ethical issues inherent to the utilisation of preimplantation genetic diagnosis for gender selection in infertile patients anticipating undergoing a medically indicated assisted reproductive technique procedure. Performance of preimplantation genetic diagnosis per request specifically for gender selection by an infertile couple undergoing medically indicated assisted reproductive technique may not breach the principles of ethics, and is unlikely to alter the population balance of sexes.', 'One possible use of PGD is to perform gender selection for couples whose offspring are at increased risk of disorders that do not follow Mendelian inheritance, but which are substantially more common in one sex than another (unequal sex incidence). Here, we examine the clinical and ethical issues to be considered prior to offering PGD gender selection to reduce the risk of a child being affected by a non-Mendelian condition with unequal sex incidence.

It is argued that using PGD for sex selection is a treatment option that can be ethically offered to couples who desire to use this technology to plan their families.', 'Another concern is the use of this technology for nongenetic disorders such as gender selection.

What is the risk in G-CSF treatment for severe congenital neutropenia? | ['We obtained serial hematopoietic samples from an SCN patient who developed AML 17 years after the initiation of G-CSF treatment.

Can clonidine be used to reduce agitation in children. | ['Children receiving clonidine immediately after anesthesia induction had statistically significant improvement in postoperative agitation at the 15-minute mark (P = .096) and last score obtained (P = .095) using the Watcha scale.', 'Clonidine has proven to be effective in reducing the incidence of post-operative agitation at a higher dose (3 and 2 μg kg⁻¹).', 'Post-anaesthetic agitation was observed in two patients (6.6%) in group 1, eight patients (26.6%) in group 2 as compared to 12 patients (40%) in group 3 after 15 min of post-operative observation.', 'The mean scores in group 1 at 15 and 30 min were significantly lower than those in group 3 (P value <0.05)', 'Caudal clonidine at a lower dose (1 μg kg⁻¹) could be effective in reducing the incidence of sevoflurane-induced emergence agitation in children undergoing urogenital and lower limb surgery without any significant adverse effects.', 'Only the 4 microg kg-1 dose of clonidine was associated with a significant reduction in emergence agitation.', 'Fewer children in the clonidine 4 microg kg-1 group displayed agitation (25%) than in the midazolam group (60%) (P=0.025).', 'In comparison with midazolam, clonidine 4 microg kg-1 reduced sevoflurane-induced emergence agitation without increasing postoperative side-effects.', 'Prophylactic use of clonidine against sevoflurane-induced agitation may represent a new and promising application.', 'One hundred and twenty children were included in this study: 59 of whom received clonidine, and 61 placebo; 41% of those in the placebo group exhibited moderate-severe EA compared with only 22% of those in the clonidine group (P < 0.03).', 'Findings demonstrate that i.v. clonidine administered after induction of anesthesia significantly reduces the incidence of EA in young children, but is associated with sleepiness postoperatively.', 'Clonidine could not prevent agitation (incidence 54%, 13/24)', 'Clonidine 1.5 microg/kg did not differ from placebo with respect to postoperative agitation.', 'Clonidine is effective in treating sevoflurane-induced postanesthesia agitation in children.', 'Pain and discomfort scores were significantly decreased in the clonidine group; the incidence of agitation was reduced by 57% (P = 0.029) and the incidence of severe agitation by 67% (P = 0.064).

One patient was treated for preoperative agitation and hallucinations associated with oral midazolam. One patient was given clonidine as a premedicant. The third patient was treated for preoperative agitation and hypertension.
