The Childhood Cancer Survivor Study to 24 months after bone marrow transplantation. Hyperoxia fbrosis, chronic cough and shortness of breath with cyclophos accelerates the lung damage induced by paraquat. The pulmonary specifcity of paraquat results in part from its Excessive irradiation produces a pneumonitis and fbrosis active uptake into lung tissue. Paraquat readily accepts an electron 112,114 thought to be caused by oxygen-free radical formation. Evi from reduced nicotinamide-adenine dinucleotide phosphate and dence for synergistic toxicity with radiation exists for bleomycin, then is reoxidized rapidly, forming superoxide and other oxygen 113 busulfan, and mitomycin. The toxicity may be a result of nicotinamide-adenine 112 ity with bleomycin, cyclophosphamide, and mitomycin. Treatment with appear to show increased lung toxicity when they are part of multi exogenous superoxide dismutase has had limited and conficting 113 ple-drug regimens. Like paraquat, nitrofurantoin undergoes cyclic produced by bleomycin and busulfan. In addition, preferentially inhibits glutathione reductase, the enzyme required to nitrofurantoin inhibits glutathione reductase, an enzyme involved in regenerate glutathione, thus reducing glutathione tissue stores. The disease is usually Idiopathic pulmonary fbrosis (fbrosing alveolitis) slowly progressive with a mortality rate from 15% to greater than Pneumoconiosis (asbestosis, silicosis, coal dust, talc berylliosis) 90% depending on the study and period of follow-up.

The incidence of bleo however, epithelial cell damage that triggers the arachidonic acid mycin lung toxicity is approximately 4%, which may be affected infammatory cascade may be the initiating event. Bleomycin also oxidizes arachidonic Cyclophosphamide infrequently produces pulmonary toxicity. High oxygen concentrations produce synergistic toxicity particularly regimens containing cyclophosphamide, may predis with cyclophosphamide. Inspiratory crackles and the bibasilar reticular a decreased diffusing capacity of carbon monoxide. Spirometry tests reported to be benefcial; however, death despite corticosteroid before each bleomycin dose are not predictive of toxicity. Of the alkylating agents, only nitrogen not absolutely predictive, a drop of 20% or greater in the diffusing mustard and thiotepa have not been reported to cause fbrotic pul capacity of carbon monoxide is an indication for using alternative monary toxicity. Although discontinuation is not always necessary, and reinstitution of the drug corticosteroids have been used for a number of drug-induced pulmo may not produce recurrence of symptoms. Pneumonitis has been reported to occur up to 4 weeks fol lowing discontinuation of therapy. It is A number of alkylating agents are associated with pulmonary unknown whether intermittent (weekly) dosing, as is done for rheu fbrosis (see eTable 15-5). The incidence of clinical toxicity is matoid arthritis, decreases the risk of methotrexate-induced pulmo around 4%, although subclinical damage is apparent in up to 46% nary toxicity because pneumonitis has occurred with this form of of patients at autopsy. Loffer syndrome, rarely has been associated with pulmonary the mechanism of amiodarone-induced pulmonary toxicity is fbrosis. Amiodarone and its metabolite can damage lung tis reported to produce severe respiratory toxicity in association with sue directly by a cytotoxic process or indirectly by immunologic mitomycin. Pulmonary fbrosis associated with the ganglionic-blocking agent In a review of 39 cases, 9 patients died, and the remaining hexamethonium was frst reported in 1954 (see eTable 15-6). Of the patients who died, one half had received with use of the other ganglionic blockers. If phenytoin does produce chronic fbrosis, it would appear to be a relatively rare event.

The risk of amio Methotrexate R darone pulmonary toxicity is higher during the frst 12 months of Nitrofurantoin R therapy even at a low dosage. Patients 60 years or older have a threefold increase in risk of Griseofulvin R toxicity for each subsequent decade compared to those younger Trimethadione R 131 Sulfonamides R than 60 years of age. Radiographic changes are nondiagnostic and consist of diffuse F, frequent; I, infrequent; R, rare.

Second, it creates mares is an important step and sometimes the 192 136 an insightful ‘‘mini-aha’’ experience because best first step in treating posttraumatic sleep 193 137 most trauma survivors do not generally associate disturbance.

These 200 examples to persuade the patient to stay in treat 257 arousal symptoms represent a second symptom 201 26 ment. Following arousal, patients 202 uncontrollability or unconscious processes, some 259 usually search for ways of preventing this cycle 203 patients suggest that nightmares persist because 260 from recurring, and quite naturally they seek to 204 they are a long-term consequence of trauma (ie, 261 avoid the trigger. Others 262 instance, trauma survivors report avoiding sleep 206 believe that the persistence of nightmares is 263 onset at bedtime or re-onset in the middle of the 207 caused by malfunctioning or altered neurotrans 264 night with the hope of preventing more bad 208 mitters or a genetic predisposition. Although patients may not recognize 209 a patient initiating treatment will raise the possi 266 sleep avoidance as a conscious process, most 210 bility that nightmares are a habit or a learned 267 nightmare sufferers resonate with the schema 211 behavior (some even speak the phrase ‘‘broken 268 once they hear this sequence, which again coin 212 record’’). This relation 272 through which nightmares move from an acute 216 ship is therefore examined in a few ways in an 273 phase to a chronic disorder. First, 274 developed by Michael Hollifield, which helps 218 we discuss how nightmares might ‘‘take on a life 275 patients recognize that soon after the trauma, 219 of their own. We 278 many accounts from the empirical and theoretic 222 ask whether it seems possible that some type of 279 literature, may serve a function of emotional 223 psychotherapy could be directly targeted at the 280 adaptation to emotionally salient or traumatic 224 27–30 nightmares. The term ‘‘symptom substitution’’ is 292 closing question, ‘‘Do these nightmares and dis 236 used regarding this potential downside of treating 293 turbing dreams still provide any benefits, once 237 nightmares directly. Most suggest 298 a hint at the possibility that nightmares can take 242 anger and rage, and a few mention fear, guilt, 299 on a life of their own, which is the major focus 243 horror, or grief. Most patients 321 a reasonable ability to conduct such tests in 378 sit back to regroup, because these results do not 322 groups or individually; (6) some trauma survivors 379 resonate with what they learned or believed about 323 are surprised at their healthy capacity to image 380 nightmares. They may report either 386 to which disturbing dreams can be attributed to 330 outright difficulty as a black or blank screen, or 387 trauma (0%–100%) or to habit (0%–100%) with 331 unpleasant images that force them to open their 388 the sum of the 2 estimates equaling 100%. All indi 389 Although this exercise can be performed earlier 333 viduals are provided with behavioral tips on how 390 and later in the treatment, it is useful at this point 334 to overcome unpleasant imagery (see list of 391 because the patients have begun to experience 335 common treatment obstacles in Box 2), but we 392 some flux in their perceptions about why they still 336 focus on acknowledging the unpleasant image 393 have nightmares. Rarely, 339 stated in the context of the thoughts, feelings, 396 a few individuals who believe strongly that the 340 images paradigm, in which the patient appreciates 397 nightmares are deeply entrenched in their trauma 341 the natural flux in this system. The first 404 should probably be discouraged from doing so 348 step in this exercise is to encourage patients to 405 until some shift in their views occurs in the remain 349 recognize that imagery is a frequently experienced 406 ing sessions. Most individ 353 over stimulating themselves for fear of triggering 410 uals lie between these extremes (80–20, 50–50, or 354 more disturbing images. These patients should be encouraged to avoid working with recurring 485 429 dreams at first because they usually have more replay-like qualities, and therefore the patient is 486 430 much more likely to associate the dream with specific traumatic experiences. It often helps to explain that nightmares often exhibit similar characteris 434 491 tics or overlapping themes. Feeling uncomfortable or anxious while considering a nightmare 494 438 Although patients may find it unpleasant to consider their nightmare, they should bear in mind that 495 439 they only have to do it once. After they changed it into a new dream, they no longer have to work 496 440 with the original nightmare. Not knowing how to change the nightmare 502 446 There is no single right way to change the nightmare to create the new dream. Letting distractions get in the way 449 506 450 Because imagery work requires a safe, comfortable, and distraction-free environment, patients must do 507 451 whatever is needed to find the quiet uninterrupted time necessary for the treatment. If one is pressed 508 452 for time, then simply practice for a few minutes to keep the skill fresh in mind. Difficulty managing negative images 511 455 512 Most people can naturally image or learn to imagine pleasant scenes, but one should not hesitate to 456 work with a therapist to build this skill, if needed. Focusing on positive images and not replaying nega 513 457 tive ones is an important part of improving overall health, including more restful sleep, positive dream 514 458 imagery, and more relaxed daytime functioning. The following 6 strategies can be used to manage 515 459 unpleasant images: (1) stopping: clap hands while saying ‘‘Stop! The latter issue is dispatched 523 467 Some patients are nervous about imagery, by stating that most people require time to learn 524 468 whereas others have previously experienced how to comfortably generate pleasant images, 525 469 imagery exercises. All patients start well with a but the interval is usually measured in weeks for 526 470 1-minute session. Unpleasant 528 472 and the patients can be given instructions to prac imagery is a more difficult issue. The survivors recognize the potential importance of 530 474 average patient uses an imagery session of imagery in the mind’s eye, most will find it straight 531 475 between 5 and 10 minutes. The discus A rare or occasional patient will clearly demon 534 478 sion turns to managing unpleasant images or strate they are stuck at this point in the process. Then, 3 questions are 594 538 mares are reportedly identical to the patients’ trau asked. As such, they tend to obsess employment, the questions would be: (1) when 596 540 about this relationship and often declare they did you actually switch jobs; (2) when did you 597 541 cannot image anything because it will only bring first think about switching jobs; and (3) when 598 542 up the memory of the trauma or the nightmare, did you first picture the possibility of switching 599 543 which to them feels like the same thing. Specifi 610 unpleasant imagery; (2) activation of the imagery 554 cally, imagery rehearsal is something that humans 611 system must proceed slowly and gently; (3) know 555 engage in all the time as they practice anticipated 612 your limits and know how to overcome unpleasant 556 behaviors or experiences by imagining themselves 613 images; (4) learn to appreciate that some 557 in various new or old situations to see how they 614 unpleasant images emerge through learned 558 could behave. The final instruction is to repeat 561 618 the importance of practicing pleasant imagery by With this backdrop, each person is asked to select 562 619 selecting pleasant experiences or scenarios from something in their life they would wish to change, 563 620 one’s life.

It is an introduction to, the problem is that we know virtually nothing about but not a substitute for, the detailed description of the the differences in activation of neural mechanisms that pathophysiology of cough given in Section 4 of this determine the patterns of cough. Nor do we understand book; the latter will provide the detailed basis of the the secondary mechanisms whereby a cough, once initi mechanisms of cough, and point to future develop ated, may itself strongly inuence its own pattern by ments in the understanding and treatment of cough. The commonest cause is probably cigarette Possibly the last two features apply in part also to smoking, which has been very little studied because yawns and sighs.

These Cough can be initiated from the larynx, including its terminals link to vagal thin myelinated bres, with cell supraglottal part, from the trachea and from the larger bodies mainly in the nodose ganglia. Their membranes have receptors and chan the luminal airows and velocities would be too low to nels for these stimuli, all of which can cause cough. All these changes occur in inammatory small-diameter myelinated nerve bres, the block of conditions such as asthma, either by the direct action of which prevents cough, and all the mechanical, chemical inammatory mediators released in the tissues, or by and pathological conditions that stimulate them also the local actions of tachykinins released from C-bre induce cough.

If and for controlling breathing pattern, can have a facili humans behave like experimental animals, at least tatory effect on the cough reex [4]. But since this is the site where 3 Antitussive drugs can inhibit some components centrally acting antitussive agents act it is a topic with of the cough while leaving others intact [19,22]; for important clinical implications. This ts with experience of antitussive agents tions to second-order neurones [4,21]. The neurotransmitters involved have minated, as well as the tachykinins and glutamate, been studied and include glutamate and the tachykinins 5-hydroxytryptamine, g-aminobutyric acid, N-methyl substance P and neurokinin A [4,21]. The scope for development of novel 1 a gating process which determines whether the centrally acting antitussive drugs is great. These studies should be compared with Motor actions of cough recent evidence that the standard dose of over-the counter dextromethorphan is little more effective than Typical cough consists of four phases [1] (Fig. It 1 Inspiratory, when a near-maximal deep inspiration is is proposed that both a small dose of the antitussive and taken. This view of the importance of higher centres in 3 Expulsive, when the glottis opens and forced expira cough is supported by the observation that some pa tion takes place. Velocities as great as 28000cm/s tients with stroke exhibit a weak or absent cough reex (85% of the speed of sound) have been reported, but it [27], which may increase the likelihood of aspiration is impossible to determine the gas velocity at points of pneumonias. A similar condition is seen in Parkinson’s airway constriction, where the greatest shearing forces disease, where the cough reex may be inhibited and its will be developed. Maximum expirato Cerebral cortex Voluntary Placebo effect control of cough Sensation of irritation Cough control centre Endogenous opioids Exogenous +ve –ve opioids Respiratory area of brainstem Fig. Irritation of airway receptors may cause reex cough via a brainstem Vagus control area. A sensation of irritation nerve may cause cough via higher centres such as the cerebral cortex. Cough can be voluntarily initiated and inhibited via the cerebral cortex that inuences cough by two pathways: via the brain stem and via a descending pathway to the spinal cord. Cough can also be in Respiratory Airway irritation hibited by endogenous or exogenous muscles opioids. It is disputed whether closure of the glottis is essential for an effective cough [28]; a forced expiratory effort with an open 6. During inspira been measured accurately, perhaps because of the lack tion, the ow rate is negative; at the glottic closure, the ow is of appropriate methods. The terms based almost entirely on subjective evaluation, last phase can be divided into three parts: growing, constant and decreasing. Plasticity of the cough reex ry ow is effort independent, because it is limited by this dynamic compression. The dynamic compression in One of the most important recent advances in our creases velocity, kinetic energy of the gas, and turbu understanding of the cough reex has been the demon lence of the air passing through the compression point; stration of plasticity, at receptor, ganglionic and central these features will improve the clearing capacity of the nervous levels [7,32,33]. As already stated, the exact pattern of coughing can Whether similar mechanisms in other conditions could vary greatly, and little is known about the mechanisms lead to desensitization of cough pathways does not of this variation. This may be related to by administration of histamine, ozone or allergen the undesirability of cough from the larynx or trachea challenge in sensitized animals [7,8,32,33].

Cough frequently accompanies the common cold and is usually self-limiting, causing little more than a nuis ance [1]. In this circumstance, many individuals self An overview of current medicate, as is implied by the considerable annual diagnostic protocols expenditure on ‘over-the-counter’ antitussive prepara tions [2,3]. Although there is a close association be An effective cough involves a complex reex arc ini tween smoking and cough, smokers may become so tiated by stimulation of afferent structures, innervated accustomed to their cough that it becomes less apparent by the vagus nerve and its branches [9] (see Fig. The neurophysiological mechanisms underlying cough Despite these two well-recognized scenarios, cough have already been extensively covered elsewhere in this remains one of the most common symptoms for which book. In 1981, a protocol to evaluate patients with patients seek medical attention [5]. This approach was medical help for a chronic cough are often concerned based on the systematic evaluation, using history, that ‘something is wrong’, a number report exhaustion examination and laboratory investigations directed from sleep deprivation and many become socially self at the anatomical sites of cough receptors which com conscious [6]. Coughing can be so severe as to induce prise the afferent limb of the cough reex.
