Addi- tionally cheap 0.25 mg lanoxin free shipping, since mortality data are not population based order lanoxin 0.25mg otc, the validity of generalization is suspected. The HPE is a condition that, in its more severe forms, is associated with a high mortality rate. Nevertheless, our ability to predict the risk of mortality on an individual basis remains difficult and rarely is helpful for families regarding manage- ment and future planning. My approach is to first ask the family to tell me what they 12 Kinsman have been told about HPE and their child. Almost uniformally, they have received very grim information for obstetricians sonographers, and neonatologists. This ‘‘tell- ing their story’’ sets the stage for our relationship and allows the family to discuss their values and priorities for their child and family. After this, I readdress the risk of mortality in a more general way and stress our inability to predict for specific indi- viduals. Most deaths are from medical illnesses with a clear trend towards multisystem failure as a prelude to a terminal phase of illness. These latter problems are usually recognizable and per- mit further discussion on management and palliative. This frank approach and offer of assistance, if and when the time of a life-threatening illness occurs, puts most families at ease and allows them to focus on helping their child to stay healthy and function to the best of their potential. Complications In general, there should be no progressive neurological deterioration in HPE and in most cases some developmental milestones are attained. Early medical issues relate to: (1) craniofacial aspects airway management due to cranofacial malfunctions, (2) issues of feeding and swallowing, (3) management of endocrine issues, (4) control of seizures, (5) maintenance of normal temperature, and (6) management of tone. If neurological and=or developmental regression occurs, one should search for struc- tural or metabolic abnormalities. Occasionally, hydrocephalus has developed even in the setting of severe microcephaly. Episodes of hypoglycemia can lead to seizures and=or alterations of baseline function.

Qualitative research explores attitudes lanoxin 0.25 mg sale, behaviour and ex- periences through such methods as interviews or focus groups buy cheap lanoxin 0.25 mg on-line. As it is attitudes, behaviour and experiences 14 HOW TO DECIDE UPON A METHODOLOGY / 15 which are important, fewer people take part in the re- search, but the contact with these people tends to last a lot longer. Under the umbrella of qualitative research there are many different methodologies. If you wish to pursue any of these in more depth, useful re- ferences are included at the end of this chapter. Quantitative research generates statistics through the use of large-scale survey research, using methods such as questionnaires or structured interviews. If a market re- searcher has stopped you on the streets, or you have filled in a questionnaire which has arrived through the post, this falls under the umbrella of quantitative research. This type of research reaches many more people, but the con- tact with those people is much quicker than it is in quali- tative research. Qualitative versus quantitative inquiry Over the years there has been a large amount of complex discussion and argument surrounding the topic of re- search methodology and the theory of how inquiry should proceed. Much of this debate has centred on the issue of qualitative versus quantitative inquiry – which might be the best and which is more ‘scientific’. Different meth- odologies become popular at different social, political, historical and cultural times in our development, and, in my opinion, all methodologies have their specific strengths and weaknesses. At the end of this chap- ter references are given if you are interested in following up any of these issues. Certainly, if you were to do so, it 16 / PRACTICAL RESEARCH METHODS would help you to think about your research methodology in considerable depth. Deciding which methodology is right for you Don’t fall into the trap which many beginning (and ex- perienced) researchers do in thinking that quantitative re- search is ‘better’ than qualitative research. Neither is better than the other – they are just different and both have their strengths and weaknesses.

An EKG should be performed before and after starting treatment to detect possible cardiac conduction abnormalities order lanoxin 0.25mg online. Case reports have suggested that quetiapine may be an effective treatment for tics order lanoxin 0.25 mg amex. Tetrabenazine is a benzoquinolizine derivative that depletes the presynaptic stores of catecholamines and blocks postsynaptic dopamine receptors. Several studies have confirmed a tic-suppressing effect at doses of 25–100 mg=day. The combined use of tetrabenazine and a classical neuroleptic may permit the use of lower doses of each medication with fewer side effects, which include sedation, depression, Parkinsonism, insomnia, anxiety, and akathisia. Pergolide, a mixed D1=D2=D3 dopamine receptor ago- nist, has been shown to improve tics at a dose about one-tenth of that used in treating Parkinson’s disease, i. Side effects were mild and electrocardiograms showed no difference from control. The mechanism of action is speculated to involve presynaptic rather then postsynaptic striatal or cortical dopa- mine receptors. The distribution and interaction of classi- cal neurotransmitters within frontal–subcortical structures make it possible for a variety of neurotransmitters, in addition to dopamine, to be involved in the patho- biology of TS. Hence, it is not surprising that multiple nondopaminergic therapies have been proposed for the treatment of tic disorders, but very few have been adequately evaluated, including nicotine; donepezil, a noncompetitive inhibitor of acetylcholinesterase; delta-9-tetrahydrocannabinol, the major psychoactive ingredient of marijuana; and a variety of antiepileptic agents. Botulinum toxin which reduces muscle activity by inhibiting acetylcholine release at neuromuscular junctions, has been used success- fully in treating dystonic motor and vocal tics. Botox (mean dose of 500 units) has been injected into a variety of regions including face, back, shoulder, cervical, upper thoracic, and vocal cords. Careful consideration must be given to the proper selection of the targeted tic. Treatment of Comorbid Problems ADHD Similar to treatment in any child with this problem, a variety of behavioral and edu- cational approaches should be implemented before pharmacotherapy is considered.
