However, when to How to Select the 'Next Best' Treatment select one over another agent is not well defined. Clinicians following an Unsatisfactory Response (or use 'rules of thumb' to make these judgments, but such Intolerance) to the First Agent reasonable guesses are rarely supported by prospective RCT evidence. A major clinical problem is selecting the 'next' agent if For example, more recently, efficacy for some antidepres- the first is ineffective, only partially effective, or not well sants has been established for other psychiatric conditions tolerated. When TCAs fail, the MAOIs have roughly a 50% commonly found in the presence of major depressive disor- response rate based on both open and randomized trials der, including: (a) venlafaxine for generalized anxiety disor- (58,59).

The examiner reads the numbers to the patient slowly and clearly purchase 5mg kemadrin free shipping medicine 5658. Again order kemadrin 5 mg fast delivery medicine 93 3109, it is not clear what constitutes normal and pathological performances. Reversing the letters of a “world” is stated to be an alternative to the 100 minus 7 test in the MMSE. However, in this test the patient should be comfortable with the forward arrangement of the letters. The examiner should first say the word, and have the patient spell the word forwards before attempting to reverse the letters. Reversing the months of the year is another recommended test. A problem with this is test is that some students learn this task by rote at school, while others do not. For those without rote learning, reversing the months of the year can be quite difficult. This may too easy - it can be made more taxing by asking the patient to reverse the days of the week for a fortnight. If the impaired patient makes a start on this test, they often fail to continue into a second week. Other HCFs Medical students and trainee psychiatrists should be competent in the above. The material from this point on, however, is more esoteric and forms part of a more comprehensive assessment, and is included for reference purposes only. Various experts may be involved in such an assessment: psychiatrist, neuropsychiatrist, neurologist, behavioural neurologist, neuropsychologist and speech pathologist. Language Language is assessed in the standard psychiatric assessment through attention to the form of thought, and is a significant component of the MMSE. Thus, language could be placed in the group above, but the aspects of language assessment are not part of the standard psychiatric assessment. Aphasia Aphasia is the loss or impairment of language caused by brain damage (Benson, 1992). Another definition is interesting: “a disorder of the symbolic functions of speech”. This would make aphasia indistinguishable from the formal thought disorder of schizophrenia – but let us not embroil ourselves in a pointless debate. The patient may be aware of and frustrated by her/his expressive difficulties. The patient may be unaware of her/his difficulties and frustrated by the failure of others to respond appropriately. This form is associated with lesions of the posterior superior temporal lobe of the dominant hemisphere. Nominal aphasia In anomic aphasia the primary problem is with word finding. Output may be fluent and comprehension good, but with naming significantly disturbed. This is often the residuum when other aphasias have largely resolved. Other forms of aphasia Additional forms include conductional aphasia and transcortical aphasia. Examining aphasia Observations are made during introductory conversation and history gathering. Dysarthria Dysarthria (speech disorder due to organic disorders of the speech organs or nervous system) is a mechanical problem. It is not a form of aphasia, but as it frequently co- exists with aphasia. The patient is asked to produce the vowel “ahhhhh…” steadily for as long as possible, and to produce a sting of consonants (“puh-puh-puh.... Any tongue twister will do, a traditional favourite of neurologists is, “Around the rugged rocks, the ragged rascals ran”. Comprehension When testing comprehension, the examiner stays alert to the possibility that apraxia and agnosia may be complicating factors. The patient may be asked to, “Close your eyes”, or be given some information such as a short story and asked to repeat it in her/his own words. Comprehension should be tested both verbally and in written language. Repetition The patient is asked to repeat verbatim, short passages of normal speech. Reading ability The patient is asked to read a passage aloud. Diagnostic implications of aphasia Aphasia is rarely difficult to distinguish from schizophrenic thought disorder. Aphasia, by definition, a symptom of organic disorder, is commonly found with vascular and space occupying lesions.

The donor pancreas, duodenum, and spleen are perfused in situ with cold University of W isconsin solution and harvested en bloc with the liver. The pancreaticoduodenal graft is separated from the liver graft and prepared on the surgical back table at 4oC. The spleen is first removed by ligating the splenic artery and vein. The duodenal segment is shortened to approximately 10 cm, and the suture lines are reinforced. The common bile duct (CBD) and the superior mesenteric FIGURE 15-10 artery and vein (SM A and SM V) have been ligated previously in the Enteric drainage (ED) technique.

It has been suggested that BD affords the ability Patients who have ED experience less dehydration and m etabolic to monitor urinary amylase levels as an indicator of rejection, which acidosis and, as a result, a reduced need for fluid resuscitation and may be useful in the setting of a solitary pancreas transplant. Finally, in patients who have ED in recipients of sim ultaneous pancreas-kidney (SPK) transplant in the Foley catheter can be rem oved within several days, whereas whom kidney function serves as a marker of rejection monitoring of patients who have BD require prolonged drainage (up to 14 days) urinary amylase levels is not necessary to achieve excellent long-term to permit healing of the duodenocystostomy.
