5%. Median age of onset is 60 years, but about 10% of people with pd are younger than 45 years. The average duration of time from diagnosis to death is about 15 years. Approximately 15% of patients with pd have a firstdegree relative with the disease. 1,2 the etiology of neuron degeneration in pd remains unknown, but aging has been implicated as a primary risk factor. Other explanations for the cell death may include oxidative stress, mitochondrial dysfunction, increased concentrations of excitotoxic amino acids and inflammatory cytokines, immune system disorders, trophic factor deficiency, signal-mediated apoptosis, and environmental toxins. Conditions that may promote oxidative stress include increased monoamine oxidase-b (mao-b) metabolism or decreased glutathione clearance of free radicals. 2–5 genetic mutations such as those in lrrk2 have been linked to pd, and particular mutations may predict early versus late onset of the disease. 2,3 a combination of inducers of cell death and genetic mutations may be at play in the development of pd. 2 in pd pigmented cells in the substantia nigra that make and store dopamine are lost. When patients are diagnosed, they have lost 50% to 60% of their dopamine neurons located here, and the remaining neurons elsewhere in the central nervous system (cns) may be dysfunctional. Neurons have lost about 80% of their activity in the striatum at the onset of pd. Cortical lewy bodies along with lewy neurites in various cns locations as well as the gi system may explain some of the nonmotor symptoms of pd. 2,4,5 pathophysiology the extrapyramidal motor system controls muscle movement through pathways and nerve tracts that connect the cerebral cortex, basal ganglia, thalamus, cerebellum, reticular formation, and spinal neurons. Patients with pd lose dopamine neurons in the substantia nigra, located in the midbrain within the brainstem. The substantia nigra sends nerve fibers to the corpus striatum, which is part of the basal ganglia in the cerebrum. The corpus striatum is made up of the caudate nucleus and the lentiform nuclei that consist of the pallidum (globus pallidus) and putamen (figure 33–1).

Consequently, blocking the cox-2 enzyme is thought to result in analgesic and anti-inflammatory effects. All nsaids inhibit both the cox-1 and cox-2 enzyme isoforms, but nonselective nsaids (eg, ibuprofen, diclofenac, naproxen) are not particularly selective for one isoform over the other, whereas cox-2 inhibitors (ie, celecoxib) preferentially inhibit the cox-2 isoform. Nsaids are a reasonable first-line therapy in patients with moderate-to-severe oa. Or, as adjunctive or alternative therapy when acetaminophen fails to provide an acceptable analgesic response. Nsaids significantly reduce pain and improve functioning in patients with oa, although individual responses can vary widely. Some clinicians recommend nsaids over acetaminophen for the initial treatment of severe pain or when signs and symptoms of inflammation are present. Results from comparative trials of acetaminophen and nsaids have been equivocal, but consensus guidelines support the use of nsaids as an alternative to acetaminophen if clinical features of peripheral inflammation or severe pain are present. 8–10 unfortunately, no validated mechanism exists to identify patients who are more likely to respond to nsaids than acetaminophen. The route of administration (ie, oral or topical) should be based on affected joint(s), patient preference, ability to administer, and an assessment of risk for adverse effects of systemic nsaids. Topical administration of nsaids minimizes systemic exposure while providing pain relief comparable to that of oral nsaids, but topical nsaids are only appropriate for patients with oa of superficial joints, including hands, wrists, elbows, knees, ankles, and feet. Currently, the only commercially available topical nsaid in the united states is diclofenac, which comes in a variety of preparations, including a solution, gel, and topical patch. These products all decrease pain and improve joint function with no demonstrated superiority for any one product over others. 18–21 systemic absorption of topical diclofenac is significantly less than that of oral diclofenac. Thus, gi, cardiovascular, and renal adverse effects are rare and similar in incidence to placebo with proper administration. The most common adverse effects include application site dermatitis, pruritus, and phototoxicity. For patients with oa that affects deeper joints (eg, hip), or who have not achieved an adequate response to topical nsaids, an oral nsaid should be considered. At equipotent doses, the analgesic and anti-inflammatory activity of all oral nsaids, including cox-2–selective inhibitors, are similar. The selection of a specific oral nsaid should be based on patient preference, previous response, tolerability, dosing frequency, cost, and considering underlying gi and cardiovascular risk. Some patients respond to one nsaid better than to another.

M = mean value. 502 i cardiac disorders and limited pulmonary blood how, pge1 infusion maintains pulmonary blood flow through the ductus arteriosus. Surgical creation of a more permanent source of pulmonary blood flow (usually a blalock-taussig shunt) is undertaken as soon as possible. More complex cases (e.G., with transposition) may require more extensive palliative procedures. 4. Tetralogy of fallot (see fig. 41.9) consists of rv outflow obstruction, a ventricular septal defect (of the anterior malalignment variety), ••overriding" of the aorta. Over the ventricular septum, and hypertrophy of the right ventricle. There is a wide spectrum of anatomic variation encompassing these findings, depending particularly on the site and severity of the rv outflow obstruction. The severely cyanotic neonate with tetralogy most likely has severe rv outflow tract obstruction and a large right-to-left shunt at the ventricular level through the large ventticular septal defect. Pulmonary blood flow may be duct dependent. Immediate medical management involves establishing adequate pulmonary blood flow usually with pge1 infusion, although some have attempted balloon dilation ofthe rv outflow tract. Detailed anatomic definition particularly regarding tetralogy of fallot figure 41.9. Tetralogy offallot. Typical anatomic and hemodynamic findings include (i) an anteriorly displaced infundibular septum, resulting in subpulmonary stenosis, a large ventricular septal defect, and overriding of the aorta over the muscular septum. (ii) hypoplasia of the pulmonary valve, main, and branch pulmonary arteries. (iii) equal right and left ventricular pressures. (iv) a right-to-left shunt at ventricular level, with a systemic oxygen sanu:Arion of82%.
