The physician should base this decision on knowledge of the specific activities in which the participant will be involved, including risk of falls. Standards for Certification & Accreditation 2018 219 Spinal Instability/Abnormalities the integrity of the spinal cord is at risk when the spine is unstable. Instability can be due to disease, congenital deformity, bony abnormality or injury. Abnormalities may include spinal stenosis, vertebral spurring or other conditions that compromise the function of the spine. Orthopedic or neurologic consult for location and degree of spinal dysfunction and positional or activity precautions is essential. Precaution: · Consider positioning, ground impact during mounted activities/driving, degree of movement of the equine and mounting/dismounting activities · Pain may dictate tolerance Contraindication: · Acute, painful stages or pain resulting from mounted activities/driving · Onset of neurologic symptoms such as numbness or weakness of the extremities, changes in muscle tone or changes in bowel or bladder control Spinal Orthosis A spinal orthosis is a jacket or brace worn to support or stabilize the spine. The orthosis can be made of soft or hard material and is designed in many different lengths. The pertinent concern is whether the brace allows the participant sufficient mobility to move with the equine with a relaxed, stable, upright posture and without interfering with the movement or the comfort of the equine. If unsure of the effects on the equine, carefully observe how the client is positioned and how they move when astride. A licensed/credentialed therapist/health professional with experience and training in equine activities, the Professional Association of Therapeutic Horsemanship International Instructor, the physician/orthopedist and the participant or family need to make an informed decision as to whether equine activities are appropriate for the client or the equine. The orthotist may also be consulted for possible alternative bracing if necessary (see Equipment). Standards for Certification & Accreditation 2018 Spina Bifida Spina bifida (myelomeningocele, spina bifida cystica and myelodysplasia) is a congenital deficit in the structure of the vertebrae. The spinal cord and its protective membranes (meninges) protrude through this defect. Spina bifida is diagnosed at birth by the presence of an external sac on the back and is most common in the lumbar region. If necessary, surgery is usually performed within days after birth to close the spinal defect and cover the sac to prevent infection. The primary problems associated with spina bifida are trunk and/or lower extremity paralysis, loss of sensation and hydrocephalus (see Hydrocephalus). Spina bifida occulta is a less severe abnormality of the vertebrae, without motor or sensory deficits or hydrocephalus. All of these conditions can cause the appearance or worsening of neurologic symptoms. Therefore, the Professional Association of Therapeutic Horsemanship International Instructor and therapists need to watch the participant for the symptoms for each (see following entries). This condition prevents the spinal cord from moving freely as the participant moves, bends and grows. There can be interference to the blood supply to the spinal cord, resulting in malfunction or permanent injury to the spinal cord cells. All children with repaired myelomeningocele are at risk for tethered cord but only a few become symptomatic. Those at greatest risk are children with low-level defects, good lower extremity function and those who can walk. The appearance or worsening of spasticity As noted under spina bifida, an initial baseline assessment by the program instructor and therapist is essential, as is periodic re-evaluation. If a symptomatic tethered cord is not corrected promptly with surgery, additional permanent loss of function can occur. Precaution: · All children with repaired myelomeningocele need to be monitored for tethered cord symptoms. Contraindication: · If any of the symptoms of tethered cord develop, discontinue mounted activities until the physician resolves the cause of symptoms. The result is compression of the brain stem and obstruction of cerebral spinal fluid. It occurs in 85 to 99 percent of children born with spina bifida and hydrocephalus, but only about 20 to 30 percent develop symptoms. Respiratory distress such as noisy congested breathing, difficult breathing and retraction rather than expansion of the chest as air is inhaled 2. Stridor, which is harsh croupy noise while breathing, or cyanosis, which is a bluish tinge around the mouth and fingernails indicating a lack of oxygen 4.

Approximately 20% of 4-year-olds are still having regular temper tantrums, and explosive temper occurs in approximately 5% of school-age children. Prognosis There is no evidence that infants with colic have adverse longterm outcomes in health or temperament after the neonatal period. Similarly infantile colic does not have untoward longterm effects on maternal mental health. Prevention Much can be done to prevent colic, beginning with education of prospective parents about the normal pattern of infant crying. Prospective parents often imagine that their infant will cry only briefly for hunger. Increased contact and carrying of the infant in the weeks before the onset of colic may decrease the duration of crying episodes. Similarly other soothing strategies may Temper tantrums are the most commonly reported behavioral problem in 2- and 3-year-old children. The typical frequency of tantrums is approximately one per week, with a great deal of variability. The duration of each tantrum is 2 to 5 minutes, and duration increases with age. A child who has tantrums only when he or she misses a routine nap can be treated differently than a child who has frequent tantrums related to minor difficulties or disappointments. The evaluation of a child who is having temper tantrums requires a complete history, including perinatal and developmental information. These children include former premature infants and children with autism, traumatic brain injury, cognitive impairment, and Prader-Willi and Smith-Magenis syndromes. Children with rare conditions, such as congenital adrenal hyperplasia and precocious puberty, also may present with severe and persistent tantrums. Children with intellectual disability may exhibit tantrums when their developmental age is comparable to 3 to 4 years. The coexistence of other behavioral problems, such as sleep problems, learning problems, and social problems, suggests the possibility of a more serious mental health disorder. A thorough examination of the skin to identify child abuse is recommended (see Chapter 22). Laboratory studies screening for iron deficiency anemia and lead exposure are important. Other laboratory and imaging studies are performed only when the history and physical examination suggest a possible underlying etiology. Some children with excessive tantrums should have a formal developmental evaluation. Intervention begins with parental education about temper tantrums, stressing that tantrums are a normal developmental phase. The clinician can help parents understand their role in helping the child move toward self-regulation of frustration and anger. The environment can be structured to limit toddler frustration; age-inappropriate demands on the child; and hunger, fatigue, loneliness, or hyperstimulation. Children who behave well all day at day care and exhibit temper tantrums at home in the evening may be signaling fatigue or need for parental attention. Identification of underlying stress is the cornerstone of treatment because many stressors can be eliminated. Parents may consider some changes in the home environment so that they do not have to say "No" to the child as frequently. Parental ambivalence about acceptable toddler behavior also may lead to inconsistent expectations and restrictions. Helping parents clarify what behavior is allowed and what is off limits can avert the temptation to give in when the child screams loudly or publicly. Further behavioral interventions are recommended only after engaging in strategies to help the child gain control by meeting basic needs, altering the environment, and anticipating meltdowns. Recommended behavioral strategies include behavior modification with positive and negative reinforcement or extinction. During the first week of any behavioral intervention, tantrum behavior may increase. At the same time that parents are working to extinguish or decrease the tantrums, it is important that they provide positive reinforcement for good behavior. Children with brain injury and other brain disorders are at increased risk for prolonged temper Providing parents with knowledge about the temper tantrum stage and strategies for assisting the child with emotional regulation is recommended at a health care maintenance visit between 12 and 18 months of age.

Within two (2) years of obtaining employment at a local hospital, Chad will meet his career goal of working in the patient transport department. Benchmarks or short-term objectives are only required for students with disabilities who take alternate assessments aligned to the access points. However, many school districts continue to develop short-term objectives or benchmarks for all students. Transition services activity areas that must be addressed are listed on pages 17 - 18 of this guide. The measurable annual goals or short-term objectives or benchmarks must reasonably enable your child to meet his measurable postsecondary goals. Here are some examples of courses of study: · Advanced placement courses to prepare for college · Career education courses to prepare for a career · Courses in daily living skills, such as preparing meals, using public transportation and managing money Here is a course of study example for Chad: Chad is pursuing the 24-credit standard diploma via access courses. He is currently enrolled in the Access World History course in order to meet this requirement. Chad successfully took and passed an online course on life management skills last school year. The following list provides examples of transition services: · Instruction formal instruction in school, home, or community, including community-based instruction, travel training, academic and career/technical education courses, orientation and mobility training, self-determination and self-advocacy training, and extracurricular activities. For example, an occupational therapist could assist a student develop skills to maneuver throughout classroom and campus in a safe manner 90% of the time. For example, a speech and language pathologist or audiologist could assist a student with a hearing impairment to overcome barriers that prevent full participation in a physical education class. This could take the form of developing hand signals for communication and may involve working with the teacher and the other students in the class as well. For example, a student with a cognitive disability may benefit from a reader pen that scans text and reads it aloud to the student or a student with a specific learning disability, such as dyslexia, may use technology for speech to text and/or text to speech assistance. For example, if a student has a disability related to mobility, he or she may need the assistance of an aide to get to classes in a timely manner. For example, a student who needs to develop skills for independent living might need an excursion to a grocery store where lessons learned about meal-planning and nutrition can be applied in a realworld setting. For example, as a first step in preparing for a career, students may participate in career interest assessments to determine which careers include activities that they would enjoy doing. Post-school adult living preparation for important adult activities, such as those necessary for living and participating in the community, including renting an apartment, paying bills, filing for insurance, voting and getting along with others. For example, students may need instruction in the legal implication of becoming an adult. Task analysis breaks a task into individual steps that help the student remember how to complete a task. This process may include multiple types of assessments and experiences that contribute to forming a reliable direction for job placement and career development. In addition, for a comprehensive checklist of transition services that provides more age-specific details, please see the Transition Services Checklist in the Appendix (p. A statement of needed transition services and provision of transition services is included. A statement of interagency responsibilities regarding transition services is included. In the year the student is expected to meet graduation requirements, the school district must provide a notice by January 30th to the parent and student regarding the opportunity to defer the receipt of the standard diploma. The request to defer receipt of the standard diploma must be received by the school district before May 15th in order for the student to continue receiving transition or related services. Agencies can only be invited with parental consent or the consent of your child who has reached the age of majority. Youth will need to access various resources, services, and activities in their community. It is important to provide youth with disabilities training and options for transportation while they are in school so that they are prepared to travel to and from college and/or work. The Project 10 website has a page dedicated to Transportation and transportation-related resources: project10. Self-determination helps students with disabilities to: · Make their own choices · Set their own goals · Manage their own lives · Participate in decision-making 20 Self-advocacy refers to the skills necessary to be able to speak up for oneself or a cause. Self-advocacy skills include being assertive, knowing your rights, speaking up and negotiating. When educational decisions are made for students and not with them, the development of self-determination skills is not encouraged and can be inhibited (Hawbaker, 2007).

Since the adjudication of incapacity and the appointment of a guardian is a deprivation of civil and legal rights, it is desirable to find the least restrictive alternative. Types of Disabilities Warranting a Guardianship There are three basic types of disabilities that may warrant a Guardianship developmental disabilities, age-related disabilities and acquired disabilities. Developmental Disabilities In Florida, the laws regarding developmental disabilities are found in Chapter 393 of the Florida Statutes. A developmental disability is defined as a "disorder or Syndrome that is attributable to retardation, cerebral palsy, autism, spina bifida, or Prader-Willi syndrome; and that manifests before the age of 18; and that constitutes a substantial handicap that can reasonably be expected to continue indefinitely" Fl. A Guardian Advocate would be appointed once the child reaches the age of eighteen. Age-Related Disabilities An age-related disability can occur as a natural process of aging and may affect capacity in adults. Dementia, the most well-known, is a medical condition characterized by loss of memory and functioning. It usually occurs as a result of an unhealthy lifestyle or vascular problems such as a stroke. Symptoms include short term memory loss followed by problems with language and communication, orientation as to time and place, everyday problem solving, and eventually not being able to recognize people and everyday objects. The causes include disease, oxygen deprivation, head and spinal injuries, alcoholism or drug abuse, and various forms of mental illness. Lighting the Way to Guardianship and Other Decision-Making Alternatives A Manual for Attorneys and Judges, Florida Developmental Disabilities Council, Inc. A Petition to Determine Incapacity is filed with the court to determine if a person lacks the capacity to take care of his or her self and property (assets). A Petition for Appointment of Plenary Guardian (or Limited Guardian), along with an Application for Appointment as Guardian, is usually filed at the same time. Within 5 days after the petition to determine incapacity is filed, the court must appoint a committee of three members to conduct independent evaluations and file reports with the court. This committee consists of one physician, one psychiatrist, and either another physician or psychiatrist, a nurse, a social worker, or a lay person qualified to make such an evaluation. The examination consists of a physical examination, a mental health examination, and a functional assessment. The court holds a hearing to review all relevant evidence, including the reports of the examining committee. This hearing must be set within 14 days after the examining committee reports are filed with the court. It is imperative that the attorneys representing the parties have a thorough understanding of the Rules of Evidence. The committee reports are considered to be hearsay in that the non-appearance of the examining members means you are unable to cross-examine them. Therefore, it is advisable prior to the hearing to get the written consent of the adverse attorneys to the admission of the reports. If there is an objection to their admission, the committee members must be subpoenaed to testify at the hearing. An individual, a financial institution authorized and qualified to exercise fiduciary powers, or a non-profit corporation can be appointed by the court to manage some or all of the personal and property affairs of a person. In a contested guardianship, it is not uncommon for family members to file competing petitions for appointment as guardian. When this happens, the court often appoints a Professional Guardian in order to facilitate the best interests of the ward. They are appointed by the court when no family members or friends are available or willing to serve. Dismissal of Petition to Determine Incapacity "If a majority of the examining committee members conclude that the alleged incapacitated person is not incapacitated in any respect, the court shall dismiss the petition. The Application for Appointment as Guardian gets filed with the Petition to Appoint Guardian. If filing a Petition for Emergency Temporary Guardian, that would be filed along with the Petition to Appoint Guardian.

Studies have shown that, compared with a locked orthosis, stance control orthoses offer considerable advantages with regard to energy expenditure, walking speed and reduction of the strain on the contralateral side. Kannenberg "Zum klinischen Nutzen standphasenkontrollierter Orthesensysteme Eine Analyse der wissenschaftlichen Literatur" ("On the clinical uses of stance control orthois systems an analysis of the scientific literature"), published in Orthopдdie Technik 6/2011. The body moves in front of the foot, complete extension of the knee joint; the lock is released at toe-off. Mid to terminal swing phase: in the pre-swing phase, the knee joint is stabilised at 15° flexion, the knee joint is locked in full extension shortly before heel strike for the stance phase. The body moves in front of Pre-swing phase: the leg is the foot with complete unloaded, the leg fitted with extension of the knee joint. At the end of the stance phase, an active hip or knee flexor function is also required to launch the swing phase. Before initial heel contact the knee joint extension must be actively initiated to cause the orthotic knee joint to lock automatically. The pendulum effect caused by the hip movement may suffice to fully extend the knee joint.

If necessary, assess ankle movement with a goniometer using the neutral zero method. If necessary, the knee joint can be flexed for better assessment of the ankle mobility. The FreeWalk orthosis requires a connection to the foot and hence can only be used to a limited extent if there is a leg length discrepancy. If the patient has a stable ankle joint, a maximum leg length discrepancy of up to 7 cm is possible. Differences in leg length should be eliminated as much as possible, but this equalisation should be carried out individually for each patient and if necessary, in multiple steps. Specific therapy If the prerequisites described above are not entirely met, certain weaknesses may be compensated for by strength and mobility therapy, making use of a stance control orthosis an option at some point in the future. For the purpose of improving therapy, a complimentary personal home exercise programme should be developed for the patient. Therapeutic Application and Gait Training Ottobock 17 Exercises to increase mobility Physiotherapeutic techniques of manual therapy are suitable for improving mobility (in other words, passive joint mobilisation or muscle stretching techniques, depending on the diagnosis).

Introduction Gene expression is expensive, inappropriate gene expression can be harmful to cells/organisms, the proper expression of the phenotype of an organism is dependent upon expression and lack of expression of genes at appropriate times and in appropriate cells/places. A major difference is the presence in eukaryotes of a nuclear membrane, which prevents the simultaneous transcription and translation that occurs in prokaryotes. Whereas, in prokaryotes, control of transcriptional initiation is the major point of regulation, in eukaryotes the regulation of gene expression is controlled nearly equivalently from many different points. Control of gene expression basically occurs at two levels, prior to transcription and post-transcriptionally. Transcriptional control in nucleus determines which structural genes are transcribed and rate of transcription; includes organization of chromatin and transcription factors initiating transcription. Transcription factors are always present in cell and most likely they have to be activated in some way. Estrogen interferes with action of ribonuclease; prolongs vitellin production in amphibian cells. A functional enzyme is subject to feedback control; binding of an end product can change the shape of an enzyme so it no longer carries out its reaction. Some proteins are not active after translation; polypeptide product has to undergo additional changes before it is biologically functional. Gene Control in Prokaryotes In bacteria, genes are clustered into operons: gene clusters that encode the proteins necessary to perform coordinated function, such as biosynthesis of a given amino acid. In bacteria, control of the rate of transcriptional initiation is the predominant site for control of gene expression. These regulatory proteins can act both positively (activators) and negatively (repressors). The operator region is adjacent to the promoter elements in most operons and in most cases the sequences of the operator bind a -35 position is 274 Molecular Biology and Applied Genetics repressor protein. One mode of regulation is exerted upon operons that produce gene products necessary for the utilization of energy; these are: · · catabolite-regulated operons, and the other mode regulates operons that produce gene products necessary for the synthesis of small biomolecules such as amino acids. A classic example of a catabolite-regulated operon is the lac operon, responsible for obtaining energy from galactosides such as lactose. A classic example of an attenuated operon is the trp operon, responsible for the biosynthesis of tryptophan. The lac Operon Several gene codes for an enzyme in same metabolic pathway and are located in sequence on chromosome; expression of structural genes controlled by same regulatory genes. Operon is structural and regulatory genes that function as a single unit; it includes the following: 1) A regulator gene is located outside the operon; codes for a repressor protein molecule. This enzyme is inducible, since it occurs in large quantities only when lactose, the substrate on which it operates, is present. Conversely, the enzymes 276 Molecular Biology and Applied Genetics for the amino acid tryptophan are produced continuously in growing cells unless tryptophan is present. If tryptophan is present the production of tryptophansynthesizing enzymes is repressed. A second gene codes for a permease that facilitates entry of lactose into the cell. A third gene codes for enzyme transacetylase, which is an accessory in lactose metabolism. The three genes are adjacent on chromosome and under control of one promoter and operator. The regulator gene codes for a lac operon repressor protein that binds to the operator and prevents transcription of the three genes. The lac operon (see diagram below) consists of one regulatory gene (the i gene) and three structural genes (z, y, and a). The z gene codes for -galactosidase (gal), which is primarily responsible for the hydrolysis of the disaccharide, lactose into its monomeric units, galactose and glucose. The y gene codes for permease, which increases permeability of the cell to galactosides. During normal growth on a glucose-based medium, the lac repressor is bound to the operator region of the lac operon, preventing transcription.

Sex chromosome abnormalites are often detected coincidentally at amniocentesis or during investigation for infertility. When more than one additional sex chromosome is present learning disability or physical abnormality is more likely. Turner syndrome Turner syndrome is caused by the loss of one X chromosome (usually paternal) in fetal cells, producing a female conceptus with 45 chromosomes. Severely affected fetuses who survive to the second trimester can be detected by ultrasonography, which shows cystic hygroma, chylothorax, asictes and hydrops. In some infants the only detectable abnormality is lymphoedema of the hands and feet. The most consistent features of the syndrome are short stature and infertility from streak gonads, but neck webbing, broad chest, cubitus valgus, coarctation of the aorta, renal anomalies and visual problems may also occur. Intelligence is usually within the normal range, but a few girls have educational or behavioural problems. Associations with autoimmune thyroiditis, hypertension, obesity and non-insulin dependent diabetes have been reported. Growth can be stimulated with androgens or growth hormone, and oestrogen replacement treatment is necessary for pubertal development. Other X chromosomal abnormalities including deletions or rearrangements can also result in Turner syndrome. The additional chromosome usually arises by a nondisjunction error in maternal meiosis I. Educational problems are encountered more often in this group than in the other types of sex chromosome abnormalities. Mild delay with early motor and language development is fairly common and deficits in both receptive and expressive language persist into adolescence and adulthood. Mean intelligence quotient is often about 20 points lower than that in siblings and many girls require remedial teaching although the majority attend mainstream Figure 5. Occasional menstrual problems are reported, but most triple X females are fertile and have normal offspring. It arises by nondisjunction and the additional X chromosome is equally likely to be maternally or paternally derived. Pubertal development usually starts spontaneously, but testicular size decreases from mid-puberty and hypogonadism develops. Intelligence is generally within the normal range but may be 1015 points lower than siblings. Educational difficultes are fairly common and behavioural disturbances are likely to be associated with exposure to stressful environments. Shyness, immaturity and frustration tend to improve with testosterone replacement therapy. The majority of males with this karyotype have no evidence of clinical abnormality and remain undiagnosed. Accelerated growth in early childhood is common, leading to tall stature, but there are no other physical manifestations of the condition apart from the occasional reports of severe acne. Intelligence is usually within the normal range but may be about 10 points lower than in siblings and learning difficulties may require additional input at school. Behavioural problems can include hyperactivity, distractability and impulsiveness. Although initially found to be more prevalent among inmates of high security institutions, the syndrome is much less strongly associated with aggressive behaviour than previously thought although there is an increase in the risk of social maladjustment. Individual disorders of this type are often rare, but are important because they are numerous. Risks within an affected family are often high and are calculated by knowing the mode of inheritance and the structure of the family pedigree. Mild or late onset conditions can often be traced through many generations of a family.

Using a systematic approach has been associated with improved recall of prescription instructions. It spares the pharmacist from repeating information already known by the patient, which is an inefficient use of time. Open the Consultation When the patient is called for counseling, introduce yourself by name and state the purpose of the consultation. If the patient knows the answer to a question, the pharmacist moves on to the next question. If the patient is able to tell you what the medication is for (the first question), move to the next question. The patient may describe symptoms of a condition known to be treatable with the medication in question. After verifying that the patient knows what the medication is for, ask the second prime question. Other questions to include under the second prime question are related to these areas of concern: a) how long to take the medication; b) exactly how much or how often to take it when the medication is prescribed as needed; c) what to do when a dose is missed; and d) how to store the medication. Rather than providing facts, consider asking the patient, "What did the doctor say about how long to take this medication? After verifying patient understanding about how to take the medication, proceed to the third prime question. Research shows that patients want information about their medications, especially adverse effects, and that providing such information does not lead to the development of those reactions. Most consultations are a combination of the patient knowing some information and the pharmacist "filling in the gaps" by providing additional information as the prime questions are reviewed. Because of this, it is important to close the consultation with the final verification. Think of the final verification as asking the patient to "play back" everything learned in order to check that the information is complete and accurate. Then ask the patient if there is anything else he or she needs and offer assistance as required. The pharmacist begins the process by showing the medication to the patient; that is, by opening the bottle and displaying the contents. Then, the patient tells the pharmacist how he uses the medication by answering the questions listed in Table 3-1. Note that the doctor is omitted as a reference, because the patient should have been counseled properly by the pharmacist before this and should have all information needed for proper medication usage. The showand-tell technique enables the pharmacist to detect problems with compliance or unwanted drug effects. If the patient answers incorrectly to the second question, the patient may be noncompliant, or the physician may have changed the dosage. The second show-and-tell question also allows the pharmacist to ask the patient to demonstrate proper use of an inhaler, ophthalmic solution, or how to measure liquid doses to assure proper usage. Some pharmacists have difficulty asking the third question, fearing that they may arouse suspicion in the patient. If potential adverse effects were discussed when the patient was initially counseled, it seems natural, and certainly relevant and important, to query the patient about adverse effects at the refill visit. If new symptoms are present, explore this further using the Chief Complaint history taking. Because it is important to evaluate new symptoms critically, we will describe this in detail next. The first step is to get the patient to reveal more information about the symptom. An introductory statement such as "Tell me more about it" encourages the patient to provide more specific details. These seven focused, open-ended questions, based on Chief Com- Conduct the Counseling Session for Refill Prescriptions A similar process is used for refill prescriptions. The Show-and-Tell Questions verify patient understanding of proper use of chronic medications or medications that the patient has used in the past. Finally summarize what the patient has told you, allowing the patient to verify your understanding and correct any misinformation collected or add information omitted during initial questioning. Without proper attention to detail, many pharmacists assume that the symptom expressed is caused by a disease state and do not adequately address it. Or they may jump to conclusions about the cause of the symptom and recommend a treatment without knowing the true cause.
