Head and neck cancers Cancer of the head and neck is challenging to treat due to the presence of a large number of critical normal structures in a small, confined space. Both acute toxicity and long term treatment related morbidity from surgery and radiation are high. Proton therapy has been investigated for the treatment of head and neck cancers, particularly nasal cavity, paranasal sinus, and nasopharyngeal tumours, which are generally not amenable to surgical resection. The treatment of head and neck cancers with proton therapy is evolving, particularly as new methods for modulating beam shape and size (such as intensity modulated proton therapy) become more readily available. Paediatric malignancies Paediatric malignancies are uncommon, but devastating to patients, families, clinicians and society at large when they occur. Aggressive treatments are intended to cure children, who have many decades of life ahead of them. Nearly 50% of paediatric solid tumours are brain tumours and, unfortunately, radiotherapy has deleterious effects on the developing brain [11. Adverse effects of radiotherapy are also reported in growth and development of soft tissues, bones and nerves. Maintaining the delicate balance required to achieve treatment efficacy while minimizing toxicity is a challenge, and proton therapy provides a unique opportunity to minimize long term treatment toxicity in children treated for cancer. As such, proton therapy has been used to treat medulloblastoma, ependymoma, craniopharyngioma, rhabdomyosarcoma, neuroblastoma and many other paediatric tumours in various sites all over the body. There are numerous dosimetric studies which demonstrate the superiority of proton therapy in sparing normal tissue and decreasing total integral dose [11. Clinical data have been published for orbital rhabdomyosarcomas demonstrating excellent local control of 85%. When compared with historical controls, sparing of the optic structures, optic chiasm and temporal lobes was found to be greater [11. Similarly, retrospective data examining the use of protons for craniopharyngioma, a benign but locally destructive tumour, have shown excellent local control results of 94% with minimal toxicity, particularly in patients with subtotal resection [11. Another retrospective study in children with ependymoma treated with proton therapy shows excellent disease control while sparing normal structures such as the cochlea, hypothalamus and temporal lobes [11. The treatment of paediatric malignancies is one of the most important applications of proton therapy, particularly in cases where craniospinal irradiation is required. The potential reduction of severe late toxicity and decreased risk of secondary malignancies provide a compelling rationale to further investigate the use of proton therapy in paediatric malignancies. Emerging data on the efficacy and toxicity profile of proton therapy for a variety 178 of paediatric malignancies will be forthcoming as more children are referred to proton therapy centres for treatment. However, the existing data provide a strong case for the superiority of proton therapy for carefully selected patients, particularly those with ocular tumours, base of skull tumours or paediatric malignancies. Furthermore, randomization of patients to a less conformal radiation technique may not be ethical, and there is ongoing debate about whether true equipoise exists given the current data [11. The need for and feasibility of prospective clinical trials comparing protons with photon beam therapy is the subject of heated debate among radiation oncologists today. One of the major benefits of proton therapy is the reduction in integral dose, which may result eventually in a decreased risk of secondary malignancy as compared with photon therapy [11. At present, studies examining the use of proton therapy in nearly every tumour site are ongoing at facilities around the world. As the dosimetric parameters and delivery techniques of proton therapy continue to evolve, in particular the use of the pencil beam scanning technique to create highly conformal proton plans, the applications of proton therapy will continue to grow. In the future, the cost of building 179 and maintaining a proton therapy facility will decrease owing to increased demand, competition among commercial companies and the development of compact accelerators [11. While the cost effectiveness of proton therapy is an active area of research and debate [11. Current estimates are that 15% of patients radiated for cancer in Europe have an indication for proton radiation [11. With the current shortage of radiotherapy centres and skilled personnel in developing countries, the establishment of proton therapy centres may not be feasible in the near future. In practice, the safe delivery of a very high dose of radiation is not feasible with standard radiation techniques owing to the limited tolerance of surrounding normal tissues. Proton therapy represents a major advance in the delivery of radiotherapy that offers the advantage of effective tumour control while minimizing acute and late morbidity. Clinical implementation of proton therapy has been based on the dosimetric advantages and promising early clinical results. At present, the establishment of a proton therapy centre requires considerable financial investment, as well as physics and clinical expertise. Validation of the existing technology and techniques can be achieved in a reasonable time frame if multicentre collaboration is implemented worldwide. Because of their high velocity, protons produce more dense ionizations near the end of their path in tissue. In front of the Bragg peak the radiation dose is low, and beyond the Bragg peak the dose falls to zero over a very short distance. However, many prospective non-randomized and retrospective studies have been published, and the body of literature is growing rapidly as more proton centres are opened worldwide. Over the last decade, carbon ion radiotherapy has been applied to a number of tumours that are difficult to control with other modalities, and the number of facilities offering carbon ion radiotherapy has increased worldwide. They are located in Chiba, Gunma, Hyogo, Tosu and Kanagawa, Japan; in Lanzhou and Shanghai, China; in Heidelberg and Marburg, Germany; and in Pavia, Italy. Three other new clinical facilities are in the final stages of development in Wiener Neustadt, Austria; Lanzhou, China; and Busan, Republic of Korea. Other facilities are under construction in Marburg, Germany, and Fudan, University of Shanghai, China. Physical aspects Unlike X rays, which deposit most of their energy just below skin surface, particle beams, such as proton and heavier ion beams, show an increase in energy deposition with increasing depth. The penetration dose of these beams achieves a sharp maximum at the end of their range to form the so-called Bragg peak. In addition, ion dose localization in the tumour improves as the peak to plateau ratio increases. In this respect, carbon ion radiation is particularly outstanding because its peak to plateau ratio is larger than that of any other ion beam under certain conditions [12. For modulation of the Bragg peak to conform to a target volume, the beam lines for treatment are equipped with a pair of wobbler magnets, beam scatterers, ridge filters, multileaf collimators and a compensation bolus. Favourable dose distributions will have a steep dose fall-off at the field borders. As a consequence, more precise dose localization can be achieved with carbon ion beams compared with photon beams [12. This unique property provides high local tumour control when used for radiotherapy. This property is extremely advantageous from a therapeutic point of view in terms of increased biological effect on the tumour. The reason is that carbon ion beams form a large peak in the body, as their physical dose and biological effectiveness increase while advancing to the more deep-lying parts of the body. This quality of carbon ion beams provides promising potential for their highly effective use in the treatment of intractable cancers that are resistant to photon beams [12. In view of these unique properties of carbon ion beams, it is theoretically possible to perform hypofractionated radiotherapy using significantly smaller numbers of fractions than have been used in conventional radiotherapy. This experimental result substantiates the fact that the therapeutic ratio increases, rather than decreases, even though the fraction dose is increased. The use of these properties makes it possible to complete the therapy in a shorter time without increasing toxicity. The carbon ion beam has further advantageous biological features in that cancer tissue does not easily recover from the radiation damage it causes, the oxygen concentration in the tumour has little effect on radiosensitivity, and there are only small differences in radiosensitivity among different phases of the cell cycle. This means that carbon ion beams have the best balance of all particle beams in terms of both physical and biological dose distribution. Such unique features of carbon ions allow the treatment period to be shortened significantly as compared with conventional treatment modalities. For stage I lung cancer and liver cancer, for example, an ultrashort irradiation schedule, completed in only one or two sessions, has been achieved. Even for tumours like prostate cancer and head and neck cancers, the fractionation regimens are much shorter than those used in the most sophisticated photon intensity modulated radiation therapy and proton therapy. This means that the facility can be operated more efficiently, to offer treatment for a larger number of patients than using other modalities over the same period of time. As of January 2017, there were 61 operating proton facilities in the world, while carbon ion radiotherapy was performed at 10 facilities. There are three more institutions with carbon ion facilities currently under construction or commissioning: in Wiener Neustadt, Austria; Lanzhou, China; and Busan, Republic of Korea. A significant reduction in overall treatment time with acceptable toxicities has been achieved in most cases. As compared with standard radiotherapy, they prescribed higher total doses in smaller fractions for superficial lesions, by which they successfully obtained high local control with a relatively low rate of radiation induced reactions. Tumours of a relatively large size or irregular shape located in the vicinity of critical organs, such as the eye, spinal cord and digestive tract, are good indications for carbon ion radiotherapy. However, tumours that infiltrate or originate in the digestive tract are difficult to control with carbon ion radiotherapy alone. The patients were treated with 16 fractions for four weeks with a total dose of 48. There were 76 patients (chordoma 44, chondrosarcoma 12, olfactory neuroblastoma 9, malignant meningioma 7, and others) included in the analysis. The five year local control and overall survival rates for all patients were 88% and 82%, respectively. The five year local control and overall survival rates for chordoma patients were 88% and 87%, respectively [12. Advanced non-squamous cell carcinoma of the head and neck Between April 1997 and February 2011, 407 cases with locally advanced, histologically proven, and primary or recurrent malignant tumours of the head and neck were treated with carbon ions. Most of them were adenocarcinoma, adenoid 193 cystic carcinoma, malignant melanoma, sarcoma and the other non-squamous cell carcinomas. There were no acute reactions worse than grade 3 and no late toxicities worse than grade 2. The five year local control and overall survival rates in all cases were 73% and 53%, respectively. Based on the results of the analysis, this part of the study was divided into two additional protocols, one for bone and soft tissue sarcomas and another for mucosal malignant melanomas [12. The tumours were divided into two groups according to location: peripheral type and central type. Moreover, the fraction number and treatment time were reduced in gradual steps to 52. In this study, the five year local control rate was 90%, with a cause specific survival rate of 68% and an overall survival rate of 45%. A dose escalation study with single fraction treatment was initiated in April 2003. For the treatment of central type lung cancer, a larger number of fractions than for the peripheral type was used. To avoid serious toxic reactions for the hilum, including the main bronchus, the dose was set at 68. This trial is still ongoing, with early encouraging results in terms of local control and acceptable toxicities. Bone and soft tissue tumours As of February 2011, a total of 767 patients had been enrolled in clinical trials. Among them, sacral chordomas accounted for the largest proportion and osteosarcomas of the trunk for the next largest group. As of February 2011, 500 patients were enrolled in this study and 514 lesions in 495 patients had been analysed for six months or longer after the treatment. As of August 2011, the two year and five year local control rates were 85% and 69%, respectively. Late skin toxicities, including grade 3 in six patients and grade 4 in one patient, were also observed [12. Hepatocellular cancer A total of 403 patients with hepatocellular carcinoma were enrolled in this clinical trial. In these patients, post-treatment impairment in hepatic function was minimal, and the five year local control and survival rates were recorded as 94% and 33%, respectively. The fourth clinical study was conducted from April 2003 to August 2005, with a more hypofractionated regimen of two fractions/two days, in which 36 patients were safely treated within a dose escalation ranging from 32. Twenty-six patients were registered from April 2003 through February 2010, and dose escalation was performed from 30 to 36. Twenty-one out of 26 patients received curative resections (resection rate 81%), but the remaining five patients did not undergo surgery due to liver metastases or refusal. In the 21 surgical cases, the five year local control and overall survival rates were 100% and 53%, respectively. After a dose escalation study of gemcitabine, the radiation dose was increased by 5% from 43. The two year local control rate and two year overall survival rate were 26% and 32%, respectively [12. The three and five year local control rates were respectively 89% and 89% for patients treated with 70. Prostate cancer the therapeutic outcome of hypofractionated conformal carbon ion radiotherapy for localized prostate cancer was investigated. The study analysed the treatment results of 1084 cases observed for six months or more after carbon ion radiotherapy up to February 2011. The Gleason score, prostate-specific antigen value and clinical stage were the significant prognostic factors for the relapse-free survival rate. No difference was found in the relapse-free survival rate between the two fractionation methods (20 fractions versus 16 fractions). Out of 1005 cases followed up for at least one year, only one developed grade 3 lower urological impairment, incidences of grade 2 were 6% in the lower urinary tract and 2% in the rectum. Furthermore, the toxicity incidence was lower in the 16 fraction schedule than in the 20 fraction schedule [12. Locally advanced uterine cervical cancer As of February 2011, a total of 166 patients were enrolled in the clinical trials. Uveal melanoma and lacrimal gland tumour As of February 2011, a total of 109 patients with uveal melanoma were enrolled in the clinical trials. The three year local control rate of 97% was satisfactory and comparable to that reported for proton therapy, and the three year overall survival rate was 88% [12. Surgery for lacrimal gland cancer offers poor results because of the difficulty of total tumour eradication. So far, 22 patients have been treated, with a total dose of 48 GyE in 5 patients, and 52. The five year local control rate was 74% and the five year overall survival rate was 65%. So far, with the support of the many involved investigators, considerable evidence has been accumulated in terms of the safety and efficacy of carbon ion radiotherapy for various types of malignant tumours. Studies aimed at clarifying the greater usefulness of carbon ion radiotherapy and elucidating any advantages from hypofractionation should be considered. It is used to treat cancers which are difficult to remove during surgery, to address the concern that microscopic cancer cells may remain behind. It allows higher effective doses of radiation to be used compared with conventional radiotherapy. It is not always possible to use very high doses during conventional radiotherapy since sensitive organs are often nearby. Direct visualization of the tumour bed during surgery guarantees the most accurate dose delivery. The dosimetric properties of these four methods in terms of dose homogeneity, flexibility towards asymmetric tumour volume shapes and hence their ability to deliver a reliable dose to a given volume differ tremendously. When breast conserving treatment is likely, the tumour is excised and the surgical clearance confirmed by intraoperative pathological examination, which is also used to guide contingent re-excision in the case of close or positive margins. Dose volume histograms for the target volume (left) and the organ at risk (right) (from Nairz et al. Treatment is applied by circular applicators of different diameters; optionally, additional thoracic wall protection can be added using lead shielding.
A reduction in arousal may be positively reinforcing birth control late period purchase alesse mastercard, and thus birth control for womens health cheap 0.18mg alesse free shipping, the client may engage in self-injury more often when encountering arousal-producing stimuli (Romanczyk birth control hotline purchase 0.18 mg alesse with visa, 1986) birth control for emergency contraception purchase 0.18 mg alesse otc. There is growing evidence that pain associated with gastrointestinal problems birth control pills wiki discount alesse, such as acid reflux and gas birth control pills while breastfeeding alesse 0.18mg generic, may be associated with self-injury birth control pills definition buy alesse 0.18mg lowest price. In addition birth control pills vs hormone replacement therapy buy discount alesse on-line, some autistic individuals report that certain sounds, such as a baby crying or a vacuum cleaner, can cause pain. In all of these instances, self-injury may release beta-endorphins which would dampen the pain. In this case, stimulating one area of the body (in this case by injuring oneself) may reduce or dampen the pain located in another area of the body (Edelson, 2014). The person may not feel normal levels of physical stimulation; and as a result, he/she damages the skin in order to receive stimulation or increase arousal (Edelson, 1984). A functional analysis of behavior can identify the relationship between environmental events and behavior, and can thus accumulate information to describe the nature of the self-injury. Attention refers to social consequences of displaying self-injury, ranging from mild to severe reprimands. When self-injury results in increased attention, it is positively reinforced by serving to produce social interactions that may seldom occur otherwise for some individuals with developmental disabilities, given their limited adaptive behaviors and communicative repertoires (Cox & Schopler, 1993; Mace et al. It has been hypothesized that unresponsive environments and an inability to communicate requests appropriately may promote increasingly problematic behaviors (Carr & Durand, 1985). For instance, an individual may request something, not receive it, and then engage in selfinjurious behavior. Additionally, the behavior may be reinforced positively if the individual should, on occasion, receive the desired object or event. The individual may engage in self-injury just prior to the social interaction; and thus, he/she may avoid the social interaction before it begins. Alternatively, the individual may engage in self-injury to escape (or terminate) a social encounter that has already begun. In this case self-injury is interpreted as providing self-induced stimulation of the senses, and develops into both sensory and social reinforcement (Edelson, 1984). Self-injury as a form of self-stimulation coincides with the idea that repetitive, stereotyped movements. In direct contrast, self-injury has also been suggested to attenuate the effects of over-arousing stimuli (Murphy, 1982). If a person has poor receptive and/or poor expressive language skills, then this may lead to frustration and escalate into self-injury notably when the individual is trying to obtain desirable tangibles or activities. Combining several types of self-injury into one general behavior may make it difficult to determine different reasons for each behavior. For example, if a child engages in wrist-biting and excessive self-scratching, there may be a different reason for each behavior (Edelson, Taubman, and Lovaas, 1983). Wristbiting may be a reaction to frustration, whereas excessive scratching may be a means of self-stimulation. During data collection, salient characteristics of the self-injurious behavior are recorded, such as the frequency, duration, and severity. Specifically, information regarding the physical environment should include the setting. Other factors to be recorded include time of day and day of the week when the behaviors occur. The direct observation of target behaviors, their antecedents, and their consequences is a hallmark of functional assessment (Gresham et al, 2001). Once this information is collected, an examiner is able to determine how many times a target behavior was preceded by a specific antecedent. These results then are summarized as probabilities or percentages of behavior occurring under certain antecedents and consequence conditions (Feldman and Griffiths, 1997). Scales have also been developed specifically for children under the age of three years. Risperidone was the first drug approved in 2006 to treat behaviors associated with autism in children. These behaviors were included under the general heading of irritability, and include aggression, deliberate self-injury, and temper tantrums. A recent Cochrane review (Rana et al, 2013) examined the effectiveness of pharmacological interventions in the management of self-injurious behavior in adults with intellectual disability. The Cochrane review included only randomized, placebocontrolled trials which were completed in predominantly adult populations with intellectual disabilities. The use of antipsychotics has shifted from typical to atypical antipsychotics, primarily because of concerns about severe side effects in children. Evidence shows that atypical antipsychotics may be useful in treating certain symptoms associated with autism spectrum disorders, such as aggression, irritability, and selfinjurious behavior (McDougle et al, 2008). The largest number of studies of atypical antipsychotic agents has been reported for risperidone. Sharma and Shaw (2012) conducted a meta-analysis of the effectiveness of reducing maladaptive behaviors in autism. The database for the analyses comprised 22 studies including 16 open-label and six placebocontrolled studies. Based on the quality, sample size, and design of studies prior to 2000, the database was restricted to articles published after the year 2000. Overall, these results suggest that despite the various outcome measures utilized in these studies, there appears to be improvement in problematic behaviors with risperidone treatment. Additional placebo-controlled studies also support the short-term efficacy of low-dose risperidone in adolescents with a sub-average intellectual function and various disruptive behaviors, including aggression (Pringsheim and Gorman, 2012). Finally, other less rigorous trials of risperidone have consistently shown improvements in aggression, irritability, self-injurious behavior, temper tantrums, and mood swings in patients with autism spectrum disorders (Shea et al, 2006, Chavez et al, 2006). Both risperidone and olanzapine have been reported to reduce aggression in persons with intellectual disability (Amore et al, 2001). The registration trials were done after several promising smaller trials of children with irritability in autism suggested this drug may have relatively good efficacy (Stigler et al, 2004, 2009; ValicentiMcDermott & Demb, 2006). In a study of five children given an average of 12 mg daily for 3 months, 100% of them had improvement in their aggression, selfinjurious behavior and tantrums. A recent study by Golubchik and colleagues (2011) suggested that low-dose quetiapine may reduce aggression levels and increase sleep quality in adolescents with autism spectrum disorders. Two case reports found clozapine, in doses of 200 to 450 mg/day, effective for reducing aggression in children and adolescents with autism (Zudda et al, 1996; Chen et al, 2001). In two Japanese studies, fluvoxamine helped reduce aggression in addition to stereotypy in children with autism (Fukuda et al. Currently, fluoxetine, escitalopram, clomipramine, and sertraline are approved for major depressive disorder and obsessive-compulsive disorder in children (down to six years of age). Evidence of the efficacy of older tricyclic antidepressants with the exception of desipramine, buspirone, and venlafaxine has not been reported beyond single case reports involving only one or two subjects. Another trial (N=8) reported that naltrexone administration was associated with significantly fewer days of high frequency self-injury and significantly more days with low frequency self-injury. Naltrexone had different effects depending on the form and location of selfinjury. It also has dosedependent effects, with optimal benefits observed at doses between 0. Symons, Thompson and Rodriguez (2004) also found that males respond better than females with females often requiring extremely high doses. However, despite these positive findings, there are some paradoxical findings in the naltrexone research. In a single patient case report, lithium was used to augment fluvoxamine in the treatment of aggression. The dose was 900 mg and lithium augmentation did lead to a significant reduction in aggression (Epperson et al. While 71% of subjects were much or very much improved, side effects were present including alopecia, behavioral activation, elevated liver enzymes, sedation and weight gain. One doubleblind, placebo-controlled crossover study reported an effect of transdermal clonidine in reducing self-stimulating behaviors (Frankhauser et al, 1992). A retrospective trial of guanfacine in 80 patients ages 3-18 with autism spectrum disorders failed to reduce aggression in persons with pervasive development disorder (Posey et al, 2004). Punishment with aromatic ammonia was used to eliminate self-injurious behavior of an autistic woman during experimental sessions. The effects were reversible but were limited to experimental sessions until staff used the ammonia on the ward at all times. Singh et al (1980) conducted two experiments which investigated the effects of behavioral interventions on the self-injurious behavior of two profoundly retarded girls. In the first experiment, responsecontingent aromatic ammonia was used as the aversive stimulus to reduce the high frequency of face-slapping and face-hitting in a deaf 28 and blind girl. In the second experiment, an overcorrection procedure was used to control jaw-hitting in another girl. Rapoff et al (1980) employed a combination of multiple baseline and reversal designs to examine the effects of differential reinforcement, overcorrection, lemon juice, and aromatic ammonia on the rate of selfpoking in a profoundly retarded child. Although lemon juice suppressed and stabilized the rate of poking, aromatic ammonia produced greater suppression. There is no evidence in the scientific literature that patients with intellectual and developmental dysfunction are at any greater risk of developing adverse events. Common side effects associated with tricyclic antidepressant medications include weight gain, dry mouth, sedation, and, in some instances, cardiac conduction changes. In studies of naltrexone, there was one reported event of nausea and sedation; however, the patient was also taking clonidine for which sedation is a common side effect. Mood stabilizers, including lithium and anticonvulsant agents, often require monitoring of cardiac function, kidney function, and routine blood tests to assess for evidence of toxicity that can be associated with several serious adverse events, including coma and death. Common, less serious adverse events associated with mood stabilizers include sedation, changes in appetite and weight, and skin rash. Since these medications were developed primarily for the treatment of hypertension, studies have reported some patients who experienced non-life threatening hypotension (Robb, 2010). The results of functional assessments subsequently guide the process of selecting appropriate and functionally relevant behavioral interventions. Most research participants are male and diagnosed with severe/profound mental retardation. The authors concluded that the use of reinforcementbased interventions has increased during the past decade, whereas the use of punishment-based interventions has decreased less. Thus, aggression by individuals with developmental disabilities is believed to be a learned behavior or set of behaviors. The individual has learned that aggressing towards another individual achieves a desired outcome, i. Various positive and negative reinforcement paradigms have demonstrated success in reducing or significantly eliminating a variety of self-injurious behaviors and aggression towards persons and objects. A negative corollary is that in the absence of intervention, challenging behaviors tend to persist in individuals with developmental disabilities (Murphy et al. Traditionally, a distinction is made between positive reinforcement and negative reinforcement; however, both have the goal of eliminating an unwanted or undesirable behavior. Positive reinforcement paradigms generally reward the individual for exhibiting appropriate behaviors whereas negative reinforcement paradigms. The term punishment is controversial in that it is often interpreted as consisting of physical punishment, when in fact there are several different types of negative reinforcement paradigms that are utilized, including time-out, withholding of desirable or tangible objects, and restraint, among others. Thus, terminating an activity may be analogous to a timeout which results in actually reinforcing the very behavior one is trying to eliminate. Other reinforcement schedules are based on the concept of differential reinforcement. That is, the appropriate behaviors an individual engages in are reinforced, and the target behaviors are ignored based on a pre-identified 31 schedule. In reinforcement schedules, reinforcement can come in the form of social attention, access to preferred items or activities, or a brief break from demands (Wacker et al, 1997). By terminating the contingency between the response and the reinforcement, extinction procedures result in a decreased probability that the response will occur again. To eliminate or extinguish this behavior, eliminating the escape contingency has been shown to be an effective treatment (Iwata et al, 1990). Protective equipment, however, also is used as a method of reducing behavior maintained by sensory reinforcement (Dorsey et al, 1982). If this upsurge in behavior poses a danger to the individual and/or others, then an extinction paradigm is not a feasible option (Lerman et al, 1999). Some individuals who have developmental and/or intellectual disabilities engage in problem behaviors of sufficient severity to threaten their own lives. Eliminating the use of aversive interventions in these individuals may limit the available treatment options (Foxx et al, 2005). The key feature of the use of punishment in behavior intervention is that the punishing stimuli. Several punishment methods have demonstrated some degree of effectiveness in individuals who have autism. Contingent physical exercise consists of having individuals engage in brief physical activity immediately after an occurrence of the target behavior (Luce et al, 1980). Physical restraint can range from complete immobilization on a bed, for example, to limiting the mobility of specific body parts. Based on the limitation of movement provided by physical restraints, this option may be viewed as the most restrictive behavioral intervention. Furthermore, the application of physical restraints can make it difficult or impossible for individuals to engage in appropriate, adaptive behaviors. The goal is to fade the use of restraints gradually over time, so that individuals remain under the stimulus control of the restraints while not actually wearing them. The use of physical restraints should be conducted in a systematic manner with careful consideration being given to providing the least amount of restraint necessary to reduce harm while inhibiting adaptive behaviors as little as possible (Wallace et al, 1999). The operant function of the behavior such as aggression is identified, reinforcement is provided for the alternative response and the behavior is placed on extinction. The new behavior becomes a more effective means to achieve the desired outcome, thus the necessity to emit the less appropriate behavior is diminished. Most of these studies are single case reports or included a relatively small sample size. Initial studies focused on surgical ablation of the amygdala which has long been described as the putative anatomical structure involved in aggression. The majority of these early reports relied 34 primarily on parent, physician/nursing or ward staff observations of behavior to document improvement. In these studies, amygdalotomy was conducted on 60 patients, 14 of whom were under 14 years of age. These patients were described as irritable, excitable, distractible and assaultive and reported an initial response rate of 85% that was reduced to 68% at three to six years of follow-up. Vaernet and Madsen (1970) reported 12 female patients ages 23-69 years, six of whom were diagnosed with schizophrenia that demonstrated violently aggressive behavior with assaults on fellow patients and ward personnel, and/or a marked tendency towards selfmutilation. After bilateral amygdalodotomy there was a marked improvement in or disappearance of aggressive behavior in all but one patient. Balasubramaniam and Ramamurthi (1970) reported the results of amygdalodotomy in 100 aggressive children and adults. Unfortunately, few details of the psychiatric state preand postoperatively are given. The authors reported that 75 patients demonstrated either complete or almost complete cessation of aggressive behavior. Kiloh and colleagues (1974) reported the effectiveness of amygdaloidotomy that was performed bilaterally on 15 and unilaterally on three patients exhibiting severe aggressive or self-mutilating behavior. Nine subjects (50%) were improved a year after operation; improvement was maintained in seven (39%) for periods ranging from 27 months to nearly six years. Four non-epileptic cases had convulsions during the period of review; one patient had a persistent mild hemiparesis dating from the postoperative period. There was a tendency for epileptics to respond better than non-epileptics and for mentally retarded patients to respond poorly; however, none of the differences were statistically significant. Psychosurgery for patients with self-mutilating behavior has focused on the use of limbic leucotomy (Price et al. More recently, Jimenez-Ponce and colleagues (2011) conducted a prospective analysis of the efficacy and safety of bilateral cingulotomy and anterior capsulotomy for aggressive behavior. This article is in Spanish; the English language abstract indicates these authors studied 25 patients with a primary diagnosis of aggressiveness refractory to conventional treatment. Subjects were clinically evaluated with the Mayo-Portland adaptability inventory and the Global Assessment of Functioning score. Based on inclusion and exclusion criteria, 12 patients were finally included and surgical treated. The surgical intervention significantly decreased aggressive behavior as assessed by the Mayo-Portland adaptability inventory and the Global Assessment of Functioning score at 3 and 6 months follow-up.

The merging of these categories has been motivated by the reconceptualization of dyslexia as a language disorder in which phonological processing is deficient. The authors suggest that 2 dimensions of impairment are needed to conceptualize the relationship between these disorders and to capture phenotypic features that are important for identifying neurobiologically and etiologically coherent subgroups. As the 21st century begins, this conceptualization of the two nity to learn (Snowling, 2000). For many years, research on these two disorders guage impairments (Tallal, Allard, Miller, & Curtiss, 1997). In the 1960s dyslexia was abandon the distinction between them or whether we need to retain frequently conceptualized as a visual perceptual disorder. However, study of children with oral appeared that drew attention to problems with auditory perception language problems indicates that difficulties with semantics, syntax, and discourse will also affect literacy acquisition; in some children (so-called poor comprehenders) these difficulties may Dorothy V.

Two children with the same behavioral impairment may present with different profiles of cognitive impairment. It is also possible that two children with the same cognitive impairment will present with different profiles of reading or lanFigure 1. For example, tasks that require the segmentation of spoken behavioral level may have different causal origins. The causal words into phonemes are more difficult for readers of English than model we adopt, illustrated in Figure 2, is heavily influenced by for readers of regular orthographies such as German (Goulandris, the work of Morton and Frith (1995) and Pennington (2002) and 2003). In a similar vein, the tendency to omit grammatical markers makes a distinction between observed behavior, cognitive pro. Furthermore, the surface at the behavioral level, however, would not necessarily mean the manifestations of a cognitive impairment may change with remedisorders are qualitatively the same. For instance, children with dyslexia may, through reading, and writing are complex processes, and impairment in hard work and special education, learn to compensate for their these could reflect different underlying cognitive impairments. To difficulties, so that by adulthood they no longer appear to have a assess cognitive impairment, researchers and practitioners need to serious problem with reading (S. These are referred to as discrepancy definitions because structure and function, and the etiological level encompasses both they embody the idea that a specific deficit (in language or in genetic and environmental factors that influence cognition via their reading) occurs in the absence of poor general cognitive ability. However, this has been largely superseded by even if books are present in the home because they do not engage reliance on standard scores, which represent the statistical abnorin reading. For instance, a test of reading accuracy will lead to that paths from etiology to cognition via neurobiology are seldom different children being classified than a test of reading compresimple, and one is unlikely to see one-to-one correspondences hension (Share & Leikin, 2004). For example, there is a mismatch between nonverbal intelligence and language in tuberous sclerosis there is genetic heterogeneity; that is, the skills. The situation is much less consistent in relation to develsame phenotypic picture can be caused by mutations on either opmental dyslexia, for which discrepancy definitions have been chromosome 9 or 16 (Udwin & Dennis, 1995).

Hence, one twin would fulfill criteria abilities predicted reading attainment in both groups. It is common to find researchers selecting children attempts to classify affected children into different subtypes whose reading or language ability falls some way below age level, (Boder, 1973; Johnson & Myklebust, 1967; Rapin & Allen, 1983). Note, however, that children selexia, in which reading of regular words and nonwords is adequate lected in this fashion do not necessarily have a specific learning but reading of irregularly spelled words is impaired. A problem with all such taxonomies is that they and reading skills below the 25th or 30th percentile. We return to the issue of variation later in this review, in our taken to the diagnosis of dyslexia by those who argue that affected discussion of ways in which reading development can be impaired. Over the past 3 decades, so level of explanation before turning to the evidence concerning much evidence has accumulated for phonological deficits associetiology, neurobiology, and cognitive processes. Even more striking are the findings of distinctions to be made between a child who has particular probStark and Tallal (1988), who selected a reading disabled group lems with written texts and one whose poor reading is but one with the aim of excluding children with significant oral language manifestation of broader oral language problems. This limitation is scores within normal limits, but scored significantly below control overcome by prospective studies of children who are at a high risk levels on expressive and receptive measures. In general, such high-risk studies have provided strong evidence If deficient oral language skills are found in poor readers, this for continuities between oral and written language difficulties in raises questions about direction of causation. However, when they entered Grade 2, further evidence that semantic deficits become more of a problem all 3 had severe reading disability. On the basis of these data, as development proceeds by showing that fifth-grade children with Scarborough and Dobrich proposed a model of illusory recovery, reading disability had more pervasive semantic deficits than secillustrated in Figure 4. However, suppose a dyslexia were not simply a consequence of poor reading would be common process important for both oral and written language to demonstrate such deficits in young children before they had development is impaired in some children. Most of the early data on this question focused on delay in early oral language acquisition, followed by a period of acquisition of language milestones, with consensus emerging that apparent catch-up (illusory recovery) as normal development starts language delay was more frequent in children with dyslexia than in to plateau, with a subsequent deficit in mastery of literacy skills. The growth curve for the late developing group is identical in form to that for the typically developing group, but delayed by 12 months. The language-related skills scale on the y axis is a theoretical construct that encompasses both oral and written language attainments.
