The student and the ovum: the lack of autonomy and informed consent in trading genes for tuition.

Rising tuition costs have forced university students to become creative in finding ways to fund their education. Some female university students have decided that ova donation may be an acceptable alternative in which to pay for their tuition. This alternative presents itself because of the insufficient number of ova available for assisted reproduction and emerging stem cell technologies. Young female university students are encouraged by Internet sources and respectable electronic and print media to donate their ova in the cause of assisted reproduction for monetary compensation. While university students generally exhibit autonomy, the constraining influence of their financial predicament compromises the elements of informed consent (voluntariness, competence, capacity, understanding, and disclosure) as to their making an autonomous decision in regard to egg donation. Thus, any moral possibility of giving informed consent is negated. Informed consent can only occur through autonomy. A female university student in need of financial resources to pay for her education cannot make an autonomous choice to trade her genes for tuition. Donated ova are not only needed for assisted reproduction, but for stem cell technologies. While the long-term health of women who donate their ova is of concern (a potential risk of cancer after long term use of ovulation induction), of equal concern is the possibility of a growth in the trade of ova targeting third world and Eastern European women where the precedence for autonomy and informed consent is not well established.

The obligation of physicians to medical outliers: a Kantian and Hegelian synthesis.

BACKGROUND: Patients who present to medical practices without health insurance or with serious co-morbidities can become fiscal disasters to those who care for them. Their consumption of scarce resources has caused consternation among providers and institutions, especially as it concerns the amount and type of care they should receive. In fact, some providers may try to avoid caring for them altogether, or at least try to limit their institutional or practice exposure to them. DISCUSSION: We present a philosophical discourse, with emphasis on the writings of Immanuel Kant and G.F.W. Hegel, as to why physicians have the moral imperative to give such "outliers" considerate and thoughtful care. Outliers are defined and the ideals of morality, responsibility, good will, duty, and principle are applied to the care of patients whose financial means are meager and to those whose care is physiologically futile. Actions of moral worth, unconditional good will, and doing what is right are examined. SUMMARY: Outliers are a legitimate economic concern to individual practitioners and institutions, however this should not lead to an evasion of care. These patients should be identified early in their course of care, but such identification should be preceded by a well-planned recognition of this burden and appropriate staffing and funding should be secured. A thoughtful team approach by medical practices and their institutions, involving both clinicians and non-clinicians, should be pursued.

A suspected case of delayed onset malignant hyperthermia with desflurane anesthesia.

UNLABELLED: Desflurane has been identified as a weak triggering anesthetic of malignant hyperthermia that, in the absence of succinylcholine, may produce a delayed onset of symptoms. The prolonged interval after exposure may occur more than 6 h after the induction of anesthesia. The unintended underdosing of this patient with dantrolene and the prompt reversal of symptoms may be an attribute of the genetic expression of a weak triggering volatile anesthetic such as desflurane. IMPLICATIONS: There are multiple genetic variations for malignant hyperthermia (MH) at the ryanodine receptor. Desflurane, as a sole trigger of MH, is weak, and on two occasions in the literature (including this case), less than optimal doses of dantrolene were given with a good result. There may be possible to engineer the risk of MH out of an anesthetic once the genetics of the ryanodine receptor are better understood.

Transesophageal echocardiographic diagnosis of a liver laceration accompanied by hemodynamic instability.

Transesophageal echocardiography (TEE) is a useful adjunct in the evaluation of trauma patients, particularly in the area of aortic injury and cardiac tamponade. Little has been written on the use of this modality in the evaluation of extra-cardiac injury. We present a case of a trauma patient in whom TEE was used to evaluate hemodynamic instability; during the course of the examination a previously undiagnosed liver laceration was identified. We report the diagnosis of a liver laceration in a trauma patient by novel use of the transesophageal echocardiographic imaging modality.
