Trends in dental education 2000: the past, present and future of the profession and the people it serves. A compari- son of the educational costs and incomes of physicians and other professionals. Research involves experimentation and observation, and through this mechanism information is converted to practical application. Research has enabled advances in diagnosis, disease treatment and management and in the prevention of oral diseases and conditions. Through research, the preventive effects of fluoride for dental caries and spe- cific risk factors for periodontal disease were identified. These findings led to improved interventions and a reduction in the oral disease burden. Ongoing and future research concerning the fundamental mechanisms of oral disease will continue to drive change in dental practice. Through epidemiological and behavioral research, the dental profession has made advances in understanding the causes and progression of dental disease. Epidemiological research, through national surveys of oral health such as the National Health and Nutrition Examination Survey, has been invaluable in improving the understanding of the extent, distribution, and determinants of most dental diseases and their relationships to general health. Epidemiological research demonstrates that underserved populations shoulder a disproportionate burden of disease. For example, the death rate from oral cancer for African American males is double that for White males despite only a 20% higher incidence rate of oral cancer among African Americans. This disparity reflects the fact that African Americans have more advanced disease at the time of diagnosis and initiation of treatment. Additional epidemiological research is needed to characterize disease patterns in specific pop- ulation groups, to understand why diagnoses are not made earlier, to develop new strategies for reaching people who are at risk for oral diseases, and to evaluate treatment outcomes. Research has shown that behaviors that are under the direct control of the individual can influence the develop- ment of many dental conditions. Examples include the relationship between sucrose consumption and caries, poor oral hygiene and periodontal diseases, and smoking and oral cancer. More behavioral research is needed to design effective interventions to deter individuals from harmful personal habits and to promote preventive behaviors. The transfer of research-based knowledge and technology to practicing dental professionals has lagged behind the expansion of the knowledge base on the etiology of dental diseases and methods of treatment. Hence, there is a need to evaluate and improve the speed and quality of information and technology trans- ferred from the laboratory and other research settings to the public domain. This chapter discusses the current state of knowledge about nine defined categories of oral diseases and conditions, and identifies research directions for the future with respect to these diseases and conditions. The chapter is not inclusive of all dental diseases; rather, these disorders are intended to illustrate the direc- tions and challenges for dentistry in the future. Progress through research will challenge dentists and students with a need to become familiar with the molecular and genetic basis of oral diseases. This process will help to assure that dentistry continues as a vital and progressive profession. As the relationships between oral and systemic diseases are clarified, issues will arise about which profes- sionals have the responsibility for diagnosing and managing oral disease and who will pay for treatment. An increased understanding of the inter- profession’s recognition of the value of a constantly dependent role of personal lifestyle behaviors, profes- expanding scientific base is clear. Dental research has led to develop- transferred and disseminated effectively, efficiently ments in disease prevention, diagnosis and treat- and in a timely manner to those who will use it.

Approximately one to three photoelectrons are produced from the photocathode per 7 to 10 light photons purchase clomipramine 50mg without prescription depression counseling. Each of these photoelectrons is accelerated to the second dynode and emits two to four electrons upon impingement buy clomipramine 25mg online bipolar depression bpd. The accelerated electrons strike the successive dynodes order clomipramine 50 mg fast delivery anxiety levels, and more electrons are emitted. The process of multiplication continues until 5 8 the last dynode is reached, where a pulse of 10 to 10 electrons is produced. The pulse is then attracted to the anode and finally delivered to the pre- amplifier. The amplitude of the pulse is proportional to the number of light photons received by the photocathode and in turn to the energy of the g- ray photon absorbed in the detector. The applied voltage must be very stable, because slight changes in dynode voltage cause a great variation in electron multiplication factor. The preamplifier adjusts the voltage of the pulse (pulse shaping) and matches impedance level between the detector and the sub- sequent circuits so that the pulse is appropriately processed by the system. Linear Amplifier A linear amplifier amplifies further the signal from the preamplifier and delivers it to the pulse height analyzer for analysis of its amplitude. The amplifier gains are given in the range of 1 to 1000 by gain control knobs provided on the amplifier. Pulse-Height Analyzer g-rays of different energies can arise from a source of the same or different radionuclides or can be due to scattering of g-rays in the source and the detector. Thus, in counting a radioactive source, the pulses coming out of the amplifier may differ in magnitude. Scintillation and Semiconductor Detectors counting only those pulses falling within preselected voltage intervals or “channels” and rejects all others (see Fig. In differential counting, only pulses of preselected energies are counted by appropriate selection of lower and upper level knobs (discriminators) or the baseline and window. In scintillation cameras, however, differential counting is achieved by a peak voltage knob and a percent window knob. The peak voltage knob sets the energy of the desired g-ray, and the percent window knob sets the window width in percentage of the g-ray energy, which is normally placed symmetrically on each side of the peak voltage. In integral counting, g-rays of all energies or all g-rays of energies above a certain energy are counted by setting the appropriate lower level or base- line and bypassing the upper level or window mechanism. A rate meter can be used to display the pulses in terms of counts per minute (cpm) or counts per second (cps). These pulses can also be stored in a computer or on a magnetic tape or laser disc for processing later. Because g-rays interact with the NaI(Tl) detector by photoelectric, Compton, and pair production mech- anisms, and also because various scattered radiations from outside the detector may interact with the detector, a distribution of pulse heights will be obtained depicting a spectrum of g-ray energies. Such a g-ray spectrum may result from a single g-ray or from many g-rays in a sample. Photopeak In an ideal situation, if the g-ray photon energy is absorbed by the photo- electric mechanism and each g-ray photon yields a pulse of the same height, then each g-ray would be seen as a line on the g-ray spectrum (Fig. In reality, the photopeak is broader, which is due to various statistical vari- ations in the process of forming the pulses. Because 20–30 light photons are produced for every keV of g-ray energy absorbed, there is a statistical variation in the number of light photons produced by the absorption of a given g-ray energy in the detector. As already stated, 7 to 10 light photons are required to release 1 to 3 photoelectrons from the photocathode. Therefore, the number of pho- toelectrons that one g-ray will produce may vary from one event to another. All of the preceding statistical fluctuations in generating a pulse cause a spread in the photopeak (see Fig. Compton Valley, Edge, and Plateau When g-rays interact with the NaI(Tl) detector via Compton scattering and scattered photons escape from the detector, the Compton electrons result 90 8. A typical spectrum of the 662-keV g-ray of 137Cs illustrating the photopeak, Compton plateau, Compton edge, Compton valley, backscatter, characteristic lead K x-ray, and barium K x-ray peaks. The Compton electrons, however, can have variable energies from zero to Emax, where Emax is the kinetic energy of those electrons that are produced by the 180° Compton backscattering of the g-ray photons in the detector. At relatively high photon energy, Emax is given by the photon energy minus 256keV (Eq. Thus, the g-ray spectrum will show a continuum of pulses correspond- ing to Compton electron energies between zero and Emax. The peak at Emax is called the Compton edge, and the portion of the spectrum below the Compton edge down to about zero energy is called the Compton plateau (see Fig. The portion of the spectrum between the photopeak and the Compton edge is called the Compton valley, which results from multiple Compton scattering of a g-ray in the detector yielding a narrow range of pulses in this region. The relative heights of the photopeak and the Compton edge depend on the photon energy as well as the size of the NaI(Tl) detector. At low ener- gies, photoelectric effect predominates over Compton scattering, whereas at higher energies the latter becomes predominant. In larger detectors, g- rays may undergo multiple Compton scattering, which can add up to the absorption of the total photon energy identical to the photoelectric effect. This increases the contribution to the photopeak and decreases to the Compton plateau. Characteristic X-Ray Peak Photoelectric interactions of the g-ray photons in the lead shield around the detector can lead to the ejection of the K-shell electrons, followed by tran- Gamma-Ray Spectrometry 91 sition of electrons from the upper shells, mainly the L shell, to the K shell. The difference in binding energy between the K-shell electron (~88keV) and the L-shell electron (~16keV) appears as lead K x-ray of ~72keV. These characteristic x-ray photons may be directed toward the detector and absorbed in it and may appear as a peak in the g-ray spectrum (see Fig. These photons can be reduced by increasing the distance between the detector and the shielding material. Backscatter Peak When g-ray photons, before striking the detector, are scattered at 180° by Compton scattering in lead shielding and housing, and the scattered photons are absorbed in the detector, then a peak, called the backscatter peak, appears in the g-ray spectrum (see Fig. This peak can be mostly eliminated by increasing the distance between the shield and the detector. Iodine Escape Peak Photoelectric interaction of g-ray photons with iodine atoms of the NaI(Tl) detector usually results in the emission of characteristic K x-rays. These x- ray photons may escape the detector, resulting in a peak equivalent to photon energy minus 28keV (binding energy of the K-shell electron of iodine).

An otherwise healthy 33-year-old man sees (D) Bismuth subsalicylate his physician for a routine physical buy clomipramine 50mg on-line volcanic depression definition. The patient (E) Sulfasalazine has no complaints and is planning on Answers and Explanations 1 generic clomipramine 75mg otc bipolar depression journal articles. Both meclizine and prome- thazine are antagonists of H1-receptors used in the treatment of motion sickness buy 75 mg clomipramine overnight delivery reactive depression definition, true vertigo, and pregnancy-associated nausea. Aprepitant is the first available substance P antagonist used for the prevention of both sudden and delayed chemotherapy-induced nausea and vomiting. Scopolamine is a cholinergic antagonist that is likely associated with all the patient’s new symptoms. Dronabinol can cause sedation, dry mouth, psychotic effects, and orthostatic hypotension. The other agents, sibutr- amine, phentermine, and dextroamphetamine, are used to aid in weight loss. Cimetidine is a competitive inhibitor of the P-450 system, which thereby increases the half-life of warfarin. The other H2-blockers, including ranitidine, famotidine, and nizatidine, are not metabolized by the P-450 system. Propantheline is a choliner- gic agent used in conjunction with other agents, and rarely alone. Poor gastric emptying is a manifestation of the neuropathy that accompanies long-standing diabetes. Metoclopramide is a prokinetic agent used in the treatment of diabetic gastroparesis. Pepto Bis- mol is added in the case of peptic ulcers due to Helicobacter pylori (H. Bismuth subsalicylate is effective for both the treatment and prophylaxis of traveler’s diarrhea, most often due to Escherichia coli (E. Loperamide and diphenoxylate are good to treat diarrhea, but generally are not used for prophylaxis. Megestrol acetate is used as an appetite stimulant and results in weight gain in some patients with cancer. Aprepitant, lorazepam, and ondansetron, while having different mechanisms, are all used for nausea and vomiting, which he may experience eventually with his chemotherapy. Bismuth subsalicylate is used to treat traveler’s diarrhea, and sulfasalazine is used treat such inflammatory bowel disease, such as Crohn disease. The goal of therapy is to decrease airway resistance by increasing the diameter of the bronchi and decreasing mucus secretion or stagnation in the airways. Asthma is characterized by acute episodes of bronchoconstriction caused by underlying air- way inflammation. A hallmark of asthma is bronchial hyperreactivity to numerous kinds of en- dogenous or exogenous stimuli. In asthmatic patients, the response to various stimuli is amplified by persistent inflammation. Antigenic stimuli trigger the release of mediators (leukotrienes, histamine, and many others) that cause a bronchospastic response, with smooth muscle contraction, mucus secretion, and recruit- ment ofinflammatory cells such as eosinophils,basophils, and macrophages (early-phase response). Late-phase response (which may occur in hours or days) is an inflammatory response; levels of histamine and other mediators released from inflammatory cells rise again and may induce bronchospasm. Nonantigenic stimuli (cool air, exercise, nonoxidizing pollutants) can trigger nonspecific bron- choconstriction after early-phase sensitization. Chronic bronchitis is characterized by pulmonary obstruction caused by excessive production of mucus due to hyperplasia and hyperfunctioning of mucus-secreting goblet cells. Rhinitis is a decrease in nasal airways due to thickening of the mucosa and increased mucus secretion. Rhinitis may be caused by allergy, viruses, vasomotor abnormalities, or rhinitis medicamentosa. Adrenergic agonists stimulate b2-adrenoceptors, resulting in relaxation of bronchial smooth muscle. These agentsalso inhibit the releaseof mediatorsand stimulate mucociliaryclearance. Adrenergic agonists are useful for the treatment of the acute bronchoconstriction (exacerba- tions) of asthma. Depending on biologic half-life of the drug, these agents are used both for quick relief and for long-term control. The use of short-acting, inhaled b2-adrenoceptor agonists on a daily basis, with increasing necessity of use, indicates the need for additional long-term pharmacotherapy. Albuterol, levalbuterol, pirbuterol, metaproterenol (1) These agents have enhanced b2-receptor selectivity. Nonselective agents (1) Isoproterenol is a relatively nonselective b-receptor agonist and a potent bronchodila- tor. Isoproterenol is most effective in asthmatic patients when administered as an inhal- ant. During an acute attack, dosing every 1–2 hours is typically required; oral preparations are administered 4 times daily (qid). Epinephrine can be administered as an inhalant or subcutane- ously (in emergency circumstances); onset of action occurs within 5–10 minutes, and duration is 60–90 minutes. Salmeterol (Serevent), formoterol (Foradil) (1) These agents are administered as inhalants but have a slower onset of action and a lon- ger duration of action than the short-acting preparations. Terbutaline is a moderately specific b2-agonist that is currently available for injection or as a tablet. As with the other mixed b-adrenoceptor agonists, systemic use is cardiostimulatory. These adverse effects are minimized by inhalant delivery of the adrenergic agonists directly to the airways. Structures of methylxanthines, including xanthine, caffeine, theophylline, and theobromine. For asthma, the most frequently administered methylxanthine is theophylline (1,3- dimethylxanthine). Because of the limited solubility of theophylline in water, it is complexed as a salt, as in ami- nophylline and oxtriphylline. Methylxanthines cause bronchodilation by action on the smooth muscles in the airways. The exact mechanism remains controversial; some data suggest that it is an adenosine- receptor antagonist (adenosine causes bronchoconstriction and promotes the release of histamine from mast cells).

Dumping syndrome refers to a spectrum of vasomotor symptoms that occur after peptic ulcer surgery order clomipramine 75 mg without prescription anxiety 24 hours a day, including tachycardia purchase clomipramine 50 mg on line depression nos icd 9, light-headedness generic 75 mg clomipramine overnight delivery depression symptoms nice, and diaphoresis. It can occur within 30 min of eating and is related to rapid delivery of hyperosmolar contents to the proximal small intestine, resulting in large fluid shifts. A late dumping syndrome can also occur, with similar symptoms developing 90 min to 3 h after eating. It is related to meals containing large amounts of simple carbohydrates and thus causes insulin surges and hy- poglycemia. Bile reflux gastropathy presents after partial gastrectomy with abdominal pain, early satiety, and vomiting. Histologic examination reveals minimal inflammation but extensive epithelial injury. Finally, postvagotomy diarrhea occurs in 10% of patients after peptic ulcer surgery. These patients usually complain of severe diarrhea that occurs 1 to 2 h after meals. Carbohydrates in the diet are composed of starches, disaccharides (lactose, sucrose), and glucose. Only monosaccharides (glucose, galactose) are absorbed in the small intestine so that starches and disaccharides must be digested before absorption. Lactose, the disaccharide present in milk, requires digestion by brush border lactase into glucose and galactose. Lactase is present in the intestinal brush border in all species during the postnatal period but disappears except in humans. There are marked racial differences in the persistence of lactase, with Asians having among the highest prevalence of lactase deficiency and Northern Europeans having the lowest preva- lence. In primary lactase deficiency other aspects of intestinal nutrient absorption and brush border function are normal. Symptoms usually arise in adolescence or adulthood and consist of diarrhea, abdominal pain, cramps, bloating, and flatus after the consump- tion of milk products. Treat- ment involves avoidance of foods with a high lactose content (milk, ice cream) and use of oral galactosidase (“lactase”) enzyme replacement. The efficacy of the enzyme replacement treatments varies with the product, the food, and the individual. Viokase is used in patients with chronic pancreatic insuffi- ciency (chronic pancreatitis, resection, cystic fibrosis) and contains amylase, protease, and lipase. Metoclopramide is a promotility agent and will not help symptoms of lactase defi- ciency. Both acute hepatitis A and hepatitis B infections may be characterized by high transaminases. Therefore, progression to cirrhosis and hepatoma is increased in pa- tients with chronic hepatitis C infection. Acetaminophen remains one of the major causes of fulminant hepatic failure and is managed by prompt administration of N-acetylcysteine. It often presents with jaundice, painful hepatomegaly, ascites, and elevated transaminases. Pseudomembranous colitis is the pathologic manifestation of extensive infection with Clostridium difficile, as not all patients who develop diarrheal illness due to C. Pathologically pseudomembranes consist of fibropurulent debris that adheres to the damaged colonic mucosa. Pseudomembranes may develop in other causes of colitis, including ischemic coli- tis. The surface epithelium is denuded, and the underlying colonic mucosa is diffusely infiltrated with neutrophils. The colonic crypts are distended by mucopurulent material that becomes the pseudomembranes when the crypts rupture. Is- chemic colitis may rarely form pseudomembranes that appear similar on colonoscopy, and it may be difficult to differentiate pseudomembranous colitis from ischemic colitis from that caused by C. However, in this case, the patient’s clinical presentation is more consistent with C. In addition, the recent administra- tion of fluoroquinolone antibiotics should raise the suspicion of C. A more typical appearance of ischemic colitis on colonoscopy is patchy mucosal edema with bluish discoloration and subepithelial hemorrhage. Salmonella causes ileitis and colitis with marked mucosal edema and enlargement of Peyer’s patches. Ulcerative colitis and Crohn’s disease would not typically produce pseudomembranes, but would be associated with deep ulcerations of the mucosa, which are not apparent here. One shortcoming of this method is the inability to differentiate the fraction of conjugated bilirubin that is bound to albumin. Al- bumin-linked bilirubin (biliprotein) has a longer half-life (12–14 days) in the serum than the free form (4 h), which accounts for one of the enigmas of jaundiced patients with liver dis- ease: the elevated serum bilirubin level declines more slowly than expected in some patients who are otherwise recovering well. Bilirubin is insoluble in serum and must be bound to albumin before it can be trans- ported to the liver. At the hepatocyte, bilirubin is able to passively be absorbed and reach the endoplasmic reticulum. The enzyme glutathione S-transferase B appears to reduce efflux of bilirubin out of the hepatocyte. In the endoplasmic reticulum, bilirubin is conjugated to glu- curonic acid yielding bilirubin mono- and diglucuronide. Conjugated bilirubin is trans- ported into the bile canalicular system via an active process by multiple drug resistance protein 2. In the terminal ileum, bacterial glucuronidases unconjugate the conjugated biliru- bin. Unconjugated bilirubin is further reduced into urobilinogen in the terminal ileum. The remaining 10–20% are pas- sively absorbed into the portal venous blood and either reexcreted by the liver or the kidney.

Oprelvekin has been shown to reduce the need for platelet transfusions follow- ing myelosuppressive chemotherapy discount 50 mg clomipramine free shipping anxiety panic attack symptoms. Leucovorin is used in patients undergoing treatment with methotrexate buy clomipramine 75 mg otc mood disorder 29683, to prevent some of its side effects buy clomipramine 25 mg lowest price anxiety pills for dogs. Heparin releases lipoprotein lipase from vascular beds, which accelerates clearing of lipoproteins from plasma. The clotting factor is inactivated, which releases heparin and allows it to be recycled. Coumarin is commonly used in patients with atrial fibrillation for prevention of thromboembolic events, such as stroke. Prothrombin times should be frequently monitored in patients taking coumarin, as bleeding is a common adverse effect. Fragmin and Lovenox are low-molecular-weight derivatives of hep- arin that do not require laboratory monitoring. The vomiting reflex is a coordinated reflex controlled by a bilateral vomiting center in the dor- sal portion of the lateral reticular formation in the medulla. Pharmacologic intervention relies on inhibition of inputs or depression of the vomiting center. Subjective vertigo is prosyncopal light-headedness, which may be caused by cochlear or ves- tibular ischemia. Cholinergic antagonists reduce the excitability of labyrinthine receptors and depress con- duction from the vestibular apparatus to the vomiting center. Cholinergic antagonists are used to treat motion sickness and in preoperative situations. Cholinergic antagonists produce adverse effects that include drowsiness, dry mouth, and blurred vision. Transdermal delivery of scopolamine via a skin patch decreases the incidence of adverse effects and produces relief for 72 hours. Histamine H1-receptor antagonists include meclizine (Antivert, Bonine), cyclizine (Mare- zine), dimenhydrinate (Dramamine), and promethazine (Phenergan). These agents most likely act by inhibiting histamine pathways, and cholinergic pathways (receptor ‘‘crossover’’) of the vestibular apparatus. Histamine H1-receptor antagonists are used to treat motion sickness and true vertigo. Cyclizine and meclizine are drugs of choice for nausea and vomiting associated with pregnancy. These agents produce sedation and dry mouth and have anticholinergic side effects. These agents are contraindicated in Parkinson disease because of their extrapyramidal effects. These agents are often combined with corticosteroids such as dexamethasone (Decadron) and methylprednisolone (Solu-Medrol) to produce an enhanced antiemetic effect that is possibly due to corticosteroid inhibition of prostaglandin synthesis. Dronabinol (Marinol) is an oral preparation of D-9-tetrahydrocannabinol, the active canna- binoid in marijuana. Adverse effects include sedation, tachycardia, hypotension, and behavioral alterations simi- lar to those associated with the use of marijuana (see V X F). Diazepam is useful as atreatm entofvertigo, and it controls symptoms in Meniere disease in 60%–70% of patients. Prolonged use of some anorexigenics may lead to physical or psychologic dependence. Amphetamine, methamphetamine, dextroamphetamine, and phentermine (Adipex) act cen- trally and elevate the synaptic concentration of catecholamines and dopamine, producing a reduction in food-seeking behavior. Orlistat is a reversible lipase inhibitor used for the management of obesity and is also available over the counter. This agent is contraindicated in patients with cholestasis and malabsorption syndromes. Dronabinol (D-9-tetrahydrocannabinol) (Marinol) stimulates appetite, among its other activities. Megestrol (Megace) is a progestational agent that has a side effect increased appetite. This agent is also used as a second- or third-line therapy for breast cancer patients who have progressed on tamoxifen (see Chapter 12). Antacids are weak bases that are taken orally and that partially neutralize gastric acid, reduce pepsin activity, and stimulate prostaglandin production. Sodium bicarbonate (Alka Seltzer) (1) Sodium bicarbonate is absorbed systemically and should not be used for long-term treatment. The increase in gastric pH produced by antacids decreases the absorption of acidic drugs and increases the absorption of basic drugs. The H2-receptor antagonists, cimetidine (Tagamet), ranitidine (Zantac), famotidine (Pepcid), and nizatidine (Axid) act as competitive inhibitors of the his- tamine H2-receptor on the parietal cell. This results in a marked decrease in histamine- stimulated gastric acid secretion. Although other agents such as gastrin and acetylcholine may induce acid secretion, histamine is the predominant final mediator that stimulates parietal acid secretion. These drugs are rapidly absorbed, and effects are observed within a few minutes to hours. Therapeutic uses (1) Histamine H2-receptor antagonists are used to treat peptic ulcer disease to promote the healing of gastric and duodenal ulcers. However, when they are used as sole agents, recurrence is observed in 90% of patients. As lipophilic weak bases, these prodrugs concentrate in the acidic compartments of parietal cells where they are rapidly converted to an active thiophilic sulfonamide cation. Desired effects may take 3–4 days since not all proton pumps are inhibited with the first dose of these medications. Proton pump inhibitors are more effective for this indication than histamine H2-receptor blockers. These agents are useful in patients with Zollinger-Ellison syndrome, for reflux esophagitis, and for ulcers refractory to H2-receptor antagonists.
