The existence and sustenance of the blood bank depends on blood donors. It is imperative that the donation experience is satisfactory for the donors. Therefore this study was carried out to determine the frequency of undesirable events experienced by the blood donor as part of donor haemovigilance. This was a retrospective descriptive study of the events that occurred amongst the blood donors o...

2-4 cases with primary failure of eruption. It consists of extrusion of maxillary posterior teeth but the resisting factors for extrusion such as forces exerted by tongue, orbicularis oris muscle complex and periodontal ligament may pose a high potential for relapse. The more posterior and more number of posterior teeth involved in open bite, poorer is the prognosis for orthodontic treatment. I...

Alloimmunization is an undesirable iatrogenic effect of transfusion and transplantation. In fact, recipients can be considered as responders or not responders, in a continuum from tolerance, including organ transplantation and transfusion, to polyimmunized and refractory patients. New models and large studies have enabled a better understanding of the mechanisms that induce specific alloantibod...

Potential Induced Degradation (PID) is an undesirable property of some solar modules. The factors that enable PID (voltage, heat and humidity) exist on all photovoltaic (PV) systems, but the effect does not occur on all or even most PV systems. According to Dr. Peter Hacke of the National Renewable Energy Laboratory (NREL), “All c-Si [crystalline silicon] modules have elements of reversible and...

Space-filling properties are important in designing computer experiments. The traditional maximin and minimax distance designs consider only space-filling in the full-dimensional space; this can result in poor projections onto lower-dimensional spaces, which is undesirable when only a few factors are active. Restricting maximin distance design to the class of Latin hypercubes can improve one-di...

Both pre-registration house officers and general practitioner (GP) registrars agree on several desirable and undesirable factors that define their ideal career. These relate to fulfilling clinical work and preservation of a meaningful personal life. Many young doctors regret their choice of medicine as a career because of poor job conditions and stress and perceive career advice as inadequate. ...

Balint recognised that 'the doctor is a drug'; that 'no guidance whatever is contained in any textbook as to the dosage in which the doctor should prescribe himself'; and that there may be 'hazards' and 'undesirable sideeffects' of this type of medication. Recognition of doctor dependency is important. [1] It can be useful to look at the doctor-patient relations as 'transactions' involving both...
