Much of this work has focused on the neurobiological mechanisms of drug reinforcement, and how brain reinforcement systems adapt to chronic drug exposure because this would inevitably improve our understanding of the underlying neuropathology of drug addiction. One theory suggests that relapse of drug seeking behavior is triggered by drug-like, or proponent, processes. Another theory suggests that drug-opposite, or opponent, processes induce relapse. Both theories postulate that chronic drug use produces long-term neuroadaptations in brain reinforcement systems, and these neuroadaptations contribute directly to persistent drug craving and relapse, even after pro longed abstinence ure 6. One component of these neuroadaptations is thought to involve the process of classical conditioning, where environmental stimuli, through repeated and specific association with drug exposure, acquire the ability to trigger either drug or withdrawal-like responses when presented in the absence of the drug. In both cases, the subjects reported an intense desire to self-administer their drug of choice. Similar drug-like and withdrawal-like conditioned effects have been reported in ani mals. However, because drug craving is experi enced during both positive and negative affective states, it is possible that the underlying neurobiological mechanisms of drug craving are different from those contributing to affective state. Alternatively, drug craving associated with positive affect could differ qualitatively from the craving associated with negative affect, and thus be mediated by separate neurobiological processes. Another component of persistent drug craving following chronic drug use could involve the direct unconditioned effects of drugs on the neural substrates of motivation itself. This type of change can be thought of as an adaptive response, as neurons attempt to regain homeostasis in the continued or repeated presence of the drug. These adaptations are usually defined by pharmacological criteria, and classified as dependence, tolerance, or sensitization. These neuroadaptations can be manifested as either opponent (drug-opposite) or proponent (drug-like) processes. Thus, dependence on abused drugs can result in subjective feelings of dysphoria during withdrawal from chronic drug exposure. Although the phenomena of dependence, tolerance, and sensitization may reflect direct, unconditioned, neuroadaptations to chronic drug exposure, 4 conditioned stimuli can alter the manifestation of these phenomena, 7, 10, 11, 14 such that both conditioned and unconditioned factors ultimately contribute to opponent and proponent processes ure 6. In order to understand the relative contribution of these long-term neuroadaptations to drug craving and relapse in humans, it is important first to understand the neurochemical, pharmacological and intracellular events that trigger relapse in animal models of drug-seeking behavior ure 6. However, relapse is an operational term that can be measured directly when an animal reinitiates a particular behavioral response, for example, the lever-press response associated with drug delivery. Pretreatments and priming injections were given after extinction from 2 h of intravenous cocaine self-administration, when only intravenous saline injections were available. Hatchmarks denote the times of each self-infusion of cocaine in the cocaine phase and saline in the saline phase (From Self, D. Although there are other animal models of drug craving and drug seeking behavior, 7, 16 the reinstatement paradigm dissociates relapse from other behavioral phenomena such as reinforcement, extinction, and conditioned reinforcement, that may or may not reflect similar neurobiological processes. The neurobiological processes involved in relapse in the reinstatement model of drug-seeking behavior are the subject of this review. It important to reemphasize, however, that relapse of drug-associated responding is the variable measured in the laboratory, and subjective descriptions like drug-seeking is inferred from the results. A powerful inducer of relapse in the reinstatement paradigm is a priming injection of the self-administered drug itself. Systemic priming injections of self-administered drugs can rein state responding for opiates17, 18 and psychostimulants19-24 ure 6. In addition, opiates can reinstate responding in animals trained to self-administer psychostimulants, 17, 21 and vice versa, 20 but fail to reinstate responding for barbiturates. On the other hand, the priming produced by opiates and psychostimulants may be mediated by a separate neural substrate from that utilized by barbiturates, benzodiazepines, and ethanol. Through specific association with drug self-administration, neutral stimuli acquire the ability to induce relapse when presented on their own as priming stimuli. In animals, reports of cue-induced relapse of drug-seeking behavior are sparse, 20, 28 but reports of cue-induced drug craving in humans are numerous (see Section 6. Moreover, in animals, the priming induced by drug-associated stimuli is relatively weak when compared to the priming induced by the self-administered drug. This stressor was an effective primer in both opiate dependent and non-opiate-dependent rats, and was capable of inducing relapse even after six weeks of withdrawal from heroin. The authors noted that the priming effect of stress was greater than the priming effect of heroin itself, and was equally effective at inducing relapse whether heroin levels were maintained, or during a state of withdrawal from heroin. It is clear from these studies that presently the only known triggers of relapse in animal models of drug-seeking behavior are drug-associated stimuli (cues), stress, and priming injec tions of the drugs themselves. Although all of these stimuli can induce relapse, they have quite different effects on other aspects of animal behavior. For example, while both drugs of abuse6 and drug-associated stimuli31, 32 are capable of stimulating locomotor activity, footshock stress is generally followed by immobility rather than locomotor activity. In this regard, recent studies suggest that the motivational and stimulus properties of opiates are mediated by separate neural substrates. Further evidence for dopamine involvement in relapse is the fact that several directly acting dopaminergic agonists are powerful inducers of both cocaine and heroin-seeking behavior. The number of arrows indicate the relative ability of each stimulus to induce relapse in animal models of drug-seeking behavior. Differential localization of dopamine receptor subtypes may underlie their opposite effects on relapse of cocaine-seeking behavior (see text). In contrast, a role for the amygdala in the priming effects of drug-associated stimuli has been demonstrated. Meil and See28 recently found that excitatory amino acid lesions of the basolateral nucleus of the amygdala attenuate the ability of cocaine-associated stimuli to reinstate cocaine-seeking behavior. These amygdala lesions were effective, even when the amygdala was lesioned after the conditioning phase, indicating that the amygdala is involved in the neural circuitry through which cocaine-associated stimuli access and activate motiva tional systems. In this regard, it is interesting that similar lesions of the amygdala block the conditioned motivational, but not the conditioned locomotor, effects of cocaine. The descending outputs of the amygdala are thought to be excited by sensory information from conditioned stimuli that is received and processed through the lateral and basolateral nuclei, and then transmitted to the central nucleus. At present, this hypothesis is supported mainly by data from drug and stress-induced reinstatement studies, where dopaminergic involvement is well established. It should be noted, however, that stress-induced relapse may involve a dopamine-independent component30 and the anatomical and neuro chemical substrates of this component have not been identified. It is evident from these studies that drug-like, or proponent, neurochemical processes are powerful inducers of relapse in animal models of drug-seeking behavior. In contrast, several studies have found that drug-opposite, or opponent, processes fail to induce relapse in these animal models. For example, while priming injections of opiate agonists can induce relapse of heroin-seeking behavior, priming injections of opiate antagonists fail to induce relapse, and actually suppress responding below control levels in non-opiate-dependent animals. The authors attributed this drug-seeking behavior to extinction-like responding because the opiate-dependent animals had never expe rienced extinction conditions while in the drug-free state. Nonetheless, this finding may be relevant to other factors involved in maintaining drug use in active drug abusers. In this sense, falling levels of opiate during spontaneous withdrawal is an example of an opponent process that could play a prominent role in continued drug use on a day to day basis.

Unprotected workers who clean the printing machines by hand are exposed to high levels of 1, 2-dichloropropane vapour at close proximity, particularly in small, poorly ventilated rooms. This type of specifc and intense exposure to 1, 2-dichloropropane was observed in epidemiological studies on which the Working Group based its evaluation. Inclusion of an agent in the Monographs does not imply that it is a carcinogen, only that the published data have been examined. Equally, the fact that an agent has not yet been evaluated in a Monograph does not mean that it is not carcinogenic. Similarly, identifcation of cancer sites with sufcient evidence or limited evidence in humans should not be viewed as precluding the possibility that an agent may cause cancer at other sites. Invited Specialists do not serve as Meeting Chair or Subgroup Chair, draf text that pertains to the description or interpretation of cancer data, or participate in the evaluations. Current fnancial interests and research and employment interests during the past 4 years or anticipated in the future are identifed here. Funds were administered by the Garden City Group (Melville, New York) that reports to the court. Rusyn (Overall Chair) Invited Specialist Michael Hooker Research Center University of North Carolina 6 John W. John Lowell Butenhof was employed by 3M Company (till 2013), and is now consulting for and holds signifcant stocks of 3M Company. As a result government authorities with expert, inde of Monographs evaluations, national health agen pendent, scientifc opinion on environmental cies have been able, on scientifc grounds, to take carcinogenesis.

When ingested by humans, the eggs hatch, and the Prognosis larvae penetrate the intestinal mucosa and disseminate in the bloodstream to produce cysts; the primary sites of involve the prognosis is good in intestinal taeniasis. A associated with a few cerebral cysts may disappear in a few unilocular cyst is most common. Over years, the cyst may months; heavy brain infections may cause death or chronic reach 25 cm in diameter, although most are much smaller. The cysts of Echinococcus multilocularis are multilocular and demonstrate more rapid growth. Liver cysts present as slowly expanding tumors that may cause biliary obstruction. Hymenolepiasis extend inferiorly; 25% are on the upper surface and may be Hymenolepis nana, the cosmopolitan human tapeworm, is a asymptomatic for years. Omental torsion or hemorrhage common parasite of children; Hymenolepis diminuta, the rat from vessel erosion may occur. The former is capable of causing autoin Rupture of a pulmonary cyst causes coughing, dyspnea, fection. Larvae hatched from ingested eggs penetrate the wheezing, urticaria, chest pain, and hemoptysis; cyst and intestinal wall and then reenter the lumen to mature into worm remnants are found in sputum. Their eggs are immediately infectious for the same or focal neurologic signs and convulsions; renal cysts cause pain a new host. Laboratory Findings insects; children are infected when they ingest these insects. Presumptive diagnosis is made by a combination of radio Light infections with either tapeworm are usually asymp graphic or ultrasonographic and serologic findings. Differential Diagnosis Tumors, bacterial or amebic abscess, and tuberculosis (pul General Considerations monary) must be considered. One of the most common serious parasitic diseases, schisto somiasis, is caused by several species of Schistosoma flukes. Complications Schistosoma japonicum, S mekongi, and S mansoni involve the Sudden cyst rupture with anaphylaxis and death is the worst intestines and S haematobium, the urinary tract. If the patient survives, secondary infections species are found in eastern and southeastern Asia; S man from seeding of daughter cysts may occur. Segmental lung soni in tropical Africa, the Caribbean, and parts of South collapse, secondary bacterial infections, effects of increased America; and S haematobium in northern Africa. The cercariae penetrate human skin, migrate to the liver, and mature into adults, which then migrate Treatment through the portal vein to lodge in the bladder veins (S Definitive therapy of E multilocularis requires meticulous haematobium), superior mesenteric veins (S mekongi and S surgical removal of the cysts, preceded by careful injection of japonicum), or inferior mesenteric veins (S mansoni). Clinical the cyst with formalin, iodine, or 95% alcohol solution to disease results primarily from inflammation caused by the sterilize infectious protoscoleces, freezing the cyst wall and many eggs that are laid in the perivascular tissues or that injecting silver nitrate prior to its removal, or puncture embolize to the liver. Escape of ova into bowel or bladder aspiration/injection-reaspiration technique, which is best lumen allows microscopic visualization and diagnosis from suited for treatment of multiple cysts. A surgeon familiar stool or urine specimens, as well as contamination of fresh with this disease should be consulted. Albendazole (15 mg/kg/d for 28 days with repeat courses as Clinical Findings necessary following a 14-day rest period) is effective in many cases of E granulosus infection (hydatid disease). If the cyst Much of the population in endemic areas is infected but leaks or ruptures, the allergic symptoms must be managed asymptomatic. Symptoms and Signs Prognosis the cercarial penetration may cause a pruritic rash; larval migra Patients with large liver cysts may be asymptomatic for years. Secondary disease has a of fever and malaise as the worms migrate to their final destina much worse prognosis; about 15% of patients with this tion. Spinal cord granulomas and paraplegia due to egg embolization into the Batson plexus have been reported. Laboratory Findings the diagnosis is made by finding the species-specific eggs in Transient pruritic rash after exposure to fresh water. If no eggs are found, concentration methods should Weight loss, anorexia, hepatosplenomegaly. Peripheral eosinophilia evaluated carefully in S haematobium infection; reconstructive is common, and eosinophils may be seen in urine. Hepatic fibrosis requires careful eval uation of the portal venous system and surgical management Prevention of portal hypertension when appropriate. The best prevention is to avoid contact with contaminated fresh water in endemic areas. Efforts to destroy the snail hosts have Prognosis been successful in areas of accelerated economic development. Therapy decreases the worm burden and liver size, despite continued exposure in endemic areas. Early disease responds Treatment well to therapy, but once significant scarring or severe inflam mation has occurred, eradication of the parasites is of little A. A dosage of 40 mg/kg/d in two divided doses (S mansoni or S Gryseels B et al: Human schistosomiasis.

A total body radiographic Laboratory diagnosis may be difficult because of the small examination is advisable when blastomycosis is diagnosed in number of fungi present in some lesions, slow growth of some the skin or another nonpulmonary site. The genitourinary organisms, and difficulty in distinguishing normal colonization tract involvement characteristic of dissemination in adults is of mucosal surfaces from infection. Lymph nodes, brain, and kid stains and culture is the best method for diagnosing systemic neys may be involved. Repeat blood cultures may be negative even in the presence of intravascular infections. Laboratory Findings are useful for diagnosing coccidioidomycosis and histoplasmo sis, and antigen detection is useful for diagnosing histoplasmosis Diagnosis requires isolation or visualization of the fungus. Pulmonary specimens (sputum, tracheal aspirates, or lung the common superficial fungal infections of the hair and biopsy) may be positive with conventional stains or fungal skin are discussed in Chapter 14. An initial suppurative response is followed by an increase in the number of mononuclear cells, and then formation of noncaseating granulomas. Serologic tests are generally not helpful for diagno Residence in or travel to an endemic area. General Considerations Chronic disease can develop in the upper lobes, with cavities and fibronodular infiltrations similar to those seen in tuber the causative fungus, Blastomyces dermatitidis, is found in culosis, but unlike in tuberculosis or histoplasmosis, these soil primarily in the Mississippi and Ohio River valleys, lesions rarely caseate or calcify. In children, Primary pulmonary infection resembles acute viral, bacte infection rates are similar in both sexes. Blastomycosis should be considered when a significant pulmonary infection in an Clinical Findings endemic area fails to respond to antibiotic therapy. Chronic pulmonary or disseminated disease Primary infection is unrecognized or produces pneumonia. Patients with diabetes Mild pulmonary blastomycosis does not require treatment; mellitus are especially prone to superficial Candida infection; indeed, it is rarely recognized. Surgical debridement is required for devitalized Clinical Findings bone, drainage of large abscesses, and pulmonary lesions not A. Spontaneous thrush in older children is unusual unless they have recently received antimicrobials. Thick, odorless, cheesy discharge with intense lesions); fungemia related to intravascular devices. The vagina and labia are usually ery In immunosuppressed individuals: systemic infections thematous and swollen. Outbreaks are more frequent (renal, hepatic, splenic, pulmonary, or cerebral abscesses); before menses. Skin infection In either patient population: budding yeast and pseudo hyphae are seen in biopsy specimens, body fluids, or a. Pronounced erythema with a sharply defined margin and satellite lesions is typical. Weeping, General Considerations eroded lesions with a scalloped border are common. Speciation is important because of differences in maculopapular or pustular rash is seen. In tissue, pseu occur in premature infants, or in term infants after pro dohyphae or budding yeast (or both) are seen. The ment, and normal lymphocyte function by skin test reactiv selective absence of specific T-cell responses to Candida can ity are factors in preventing invasion. Disseminated infection lead to marked, chronic skin and nail infections called is almost always preceded by prolonged broad-spectrum chronic mucocutaneous candidiasis. The typical case consists of a severely neutropenic antibiotics and are superinfected with Candida. Symptoms persist suppressed patients is the most common enteric manifesta even when neutrophils return. It is manifested by substernal pain, dysphagia, painful liver and spleen demonstrates multiple round lesions. Laboratory Findings diarrhea in normal individuals who have predominant Can dida on stool culture has also been described, although Budding yeast cells are easily seen in scrapings or other Candida is not considered a true enteric pathogen.
