Single-gene disorders Seizures are a feature of a number of single-gene disorders associated with other features including developmental delay and other neurological signs blood pressure chart in urdu order zestril online pills. Generally, these disorders will be diagnosed on the basis of their other features. Genetic testing is not currently routinely available, and mutation confirmation rarely informs treatment at present. Examples to date have largely been channelopathies: mutations in genes coding for subunits of neuronal membrane ion channel proteins, some of which can have phenotypes with other neurological features. Early confirmation can be helpful in counselling about the expected emergence of autistic spectrum problems etc. Since optimal treatment and prognosis are strongly infiuenced by aetiology there is a case for seeing this as a heterogeneous group of conditions sharing a non-specific phenotype constrained by development (see Box 4. These usually present with seizures in the neonatal period but can occasionally present as de novo infantile spasms. Children in whom a cause cannot be identified are categorized as presumed symptomatic. Those children making an ultimately good neurodevelopmental outlook are all in this group. Metabolic and neurodegenerative disorders associated with epilepsy in infants and children 0 Seizures accompany a vast number of neurodegenerative and neurometabolic diseases. There are, however, relatively few conditions in which seizures in isolation are likely to be the presenting sign, long predating other features. Initial clue may be a low plasma creatinine (which is not normally regarded as abnormal! However this is a non-specific finding common in small infants with reduced muscle mass. Further support comes from demonstration of low urine creatinine: calcium and creatinine: protein ratios. Neurodegenerative conditions that may present with symptomatic epilepsy in older children. The progressive myoclonus epilepsies Of all indicators that epilepsy may be symptomatic of a progressive underlying neurological disease, the presence of myoclonic seizures is perhaps the most sensitive, although it is non-specific. Therapeutic ranges are only useful when pharmacokinetic variability outweighs pharmacodynamic variability (differences in the effect of a given drug concentration at the receptor which is largely genetically determined). Children may have well-controlled epilepsy with lower levels or may tolerate and require higher levels for complete seizure control. Good and bad periods can seem to come and go without apparent reason: sometimes spontaneously without changes in medication, but more problematically sometimes when a change has recently been made. Seizures do not necessarily follow simple random frequency distributions, but bear in mind the phenomenon of regression to the mean: there will usually be an average severity and frequency around which fiuctuation occurs over time. Since treatment and management changes are generally made when things are worse than average, many such changes will be followed by improvement even if there is no truly causal relationship with the symptoms. It is worth reminding families that chance might be at play and that attribution of effects should not be automatic or assumed. Complaints such as poor concentration might be due to undertreatment (incomplete seizure control), overtreatment (drug toxicity), unrelated to treatment (due to the primary cause of the epilepsy), or due to a combination of these factors. If a child is not suitable for resective surgery, palliative procedures (corpus callosotomy, multiple subpial transection) may still be considered. Typically, fat-derived to non-fat (carbohydrate and protein) calories in a 3 or 4:1 ratio. Clinical efficacy Observational studies (level 4 evidence) show a very variable, but significant complete seizure-freedom rate. Unwanted effects Primarily a function of output current and to a lesser extent pulse duration and duty cycle. Such difficulties may impact mental health and have indirect effects on seizure control. Epilepsy is an individual condition, so informed choices about activities need to be made on an individual basis depending on the type and frequency of seizures, as well as the level of control with medication. The aim should be to maximize participation in all age-appropriate aspects of life, whilst taking a realistic approach to risk management; err on the side of inclusion. Schooling Most children with epilepsy will attend mainstream school; however, there is evidence for underachievement. Neuropsychometry is recommended to define educational strengths and weaknesses and aid tailoring of educational support. It is important that pupils with epilepsy participate fully in school life and achieve their full potential. Effective communication between the teacher, parents, doctor and child must exist. For children with no additional physical or learning difficulties, or medical problems, the aim must be to enable full participation in school life with provisions made for their safety. For some children, epilepsy is part of a wider spectrum of problems needing appropriate provision either in mainstream schooling with support or in a specialist educational setting. Emotional adjustment Adjusting to a diagnosis of epilepsy involves living with unpredictability. They are currently very restrictive (arguably excessively so) and require an individual to have been seizure-free off medication for 5 yrs. Cycling A child with poorly controlled seizures should cycle away from traffic under supervision. The at-risk period for the foetus is early, quite possibly before pregnancy will have been recognized. The effect may be dose dependent, so reducing dose, rather than discontinuing drug may be an option. Tentative explanations include primary or secondary cardiac arrhythmias and/or a primary respiratory dysfunction. It is clear that the very large majority of paediatric epilepsy-related deaths are in children with significant associated neurodisability: in this group there is likely to be greater prior recognition of the presence of a life-limiting situation. Concise factual data to inform but not frighten families is a constructive approach. If appropriate comparative realistic rates of other causes of death in children and in the general population may bring things into perspective. Hazards of a false-positive diagnosis of epilepsy include exposure to unnecessary investigations, but more particularly treatment failure. It is important to be familiar with the wide range of non-epileptic processes that can give rise to paroxysmal or episodic signs or symptoms. Episodes without prominent alteration of awareness the following conditions are arranged in approximate order by the age at which they are most commonly seen. Benign neonatal sleep myoclonus A healthy infant presents at a few weeks of age with quite dramatic myoclonic movements confined entirely to sleep. The jerks, which can be quite violent, typically occur in fiurries and migrate, involving first one limb and then another in clusters of a few per second. The child is not woken or distressed by the episodes and the abnormal movements do not involve the face. No treatment is required: the phenomenon stops automatically, usually within a few months and there are no long-term neurodevelopmental implications. Shuddering spells this is a common, under-recognized variant of normal infant behaviour. Presenting the child with an interesting or novel object such as a toy (or dinner! The child typically holds his or her arms out and shows an involuntary shiver or shudder sometimes involving most of the body. Hyperekplexia this is a rare differential of neonatal seizures in its severe form. Typically due to mutations in glycine receptor genes, with failure of inhibitory neurotransmission, it causes a marked susceptibility to startle. Sudden sounds, and particularly being touched or handled, precipitate episodes of severe total body stiffening. The spells (and apnoea) can be terminated by forcibly fiexing the neck: a manoeuvre family and carers should be taught. Event severity tends to lessen with time and so long as hypoxic complications are prevented, prognosis is good. Paroxysmal tonic upgaze of infancy this involves prolonged episodes lasting hours at a time of sustained or intermittent upward tonic gaze deviation, with down-beating nystagmus on down gaze. Benign myoclonus of early infancy this is a rare disorder of early infancy with spasms closely resembling those of West syndrome. Onset is between 1 and 12 mths, and movements settle by the end of the second year. Recurrent episodes of cervical dystonia occur resulting in a head tilt or apparent torticollis. Events typically last several hours to a few days in duration and are accompanied by marked autonomic features (pallor and vomiting). The condition typically starts in infancy, resolving within the pre-school years, but such children often go on to develop hemiplegic migraine in later life. There is usually a family history of (hemiplegic) migraine and many cases are associated with calcium channel mutations. Children present with sudden onset signs consistent with vertigo (poor coordination and nystagmus). Children are often strikingly pale and may be nauseated and distressed but not encephalopathic. The condition should not be confused with the similarly named benign paroxysmal positional vertigo, a condition of adults caused by debris in the utricle of the inner ear. Self-comforting phenomena (self-gratification, masturbation) Witnessed self-comforting phenomena are common in normal toddlers, and in older children with neurological disability. A common setting is in high chairs or car travel seats fitted with a strap between the legs and with a tired or bored child. Older children often lie on the fioor, prone or supine, with tightly adducted or crossed legs. This may continue for prolonged periods, the child often becoming fiushed and quite unresponsive to attempted interruption. Parents sometimes require considerable reassurance that such behaviour is commonplace, normal and simply a source of comfort, not a sign of sexual deviancy. Ritualistic movements and behavioural stereotypies these are relatively common in young children and older children with neurological disability particularly autistic spectrum disorders. Hyperventilation and anxiety attacks the respiratory alkalosis resulting from hyperventilation is a potent cause of sensory phenomena (particularly peri-orally) and tetanic contraction of the muscles of the forearm and hand resulting in carpopedal spasm. Onset of paroxysmal attacks is from 5 yrs of age; sudden weakness, unsteady, and blurred vision, lasting minutes to hours. Attacks become milder and less frequent with age, but cerebellar signs may persist (cerebellar vermis atrophy on imaging); usually acetazolamide responsive. Paroxysmal dyskinesias A range of individually rare paroxysmal movement disorders is recognized including paroxysmal dystonias and choreoathetosis. They are generally grouped into kinesiogenic (movement induced) and non-kinesiogenic forms. Dyskinesias occurring before meals or after fasting should raise suspicion of glucose transporter deficiency (see b p. May be Dystonia often with Dystonia or chorea Dystonia, chorea or ballism unable to communicate during episode. The context in which the episode occurred and its earliest features are the most telling. Cardiac disease the importance of correctly identifying an intermittent cardiac dysrhythmia or structural cardiac disease as the cause of episodic loss of awareness is self-evident. Historic clues will include the relationship to exercise and, as stressed, prominent early pallor. The phenomenon has also been referred to as pallid syncope and in the old paediatric literature extremely confusingly as a pallid breath-holding spell (a complete misnomer for reasons that should be apparent). A sudden unexpected shock or pain results in a vagally mediated severe bradycardia or even asystole with consequent hypotension, pallor and loss of consciousness that may then lead to episodes of limb stiffening or clonic jerks. An accurate history identifies the triggers that consistently precede these episodes. Occasionally, severely affected children have come to cardiac pacemaker implantation. Common triggers include intercurrent illness, hot weather, missed meals, inadequate fiuid intake, and prolonged standing. It is typically a disease of adolescents who will be able to report a prodromal awareness of feeling cold, clammy, and unwell. If the event is not terminated by lying down in the prodromal phase, the child goes on to fall stiffiy to the ground or slump, and may exhibit brief tonic or clonic movements, or urinary incontinence. Blue breath-holding spells are primarily hypoxic in origin due to disordered respiration. As a result, the child becomes predominantly blue, limp, and may briefiy lose consciousness; again, this may result in subsequent jerking limb movements. The fiavour is very different from absence or other seizure that actively interrupts and cuts across normal activity. Movements may include pelvic thrusting, rolling or reciprocating kicking or fiailing movements.
During the meeting(s) it is important for the partnership manager to explain the rationale for the partnership blood pressure medication used for hot flashes generic zestril 10mg fast delivery, goals and expected outcomes and potential benefits of the partnership blood pressure too low order zestril in united states online. Establishing a formal agreement between the two organizations can lead to sustainable partnerships and clear expectations of roles and responsibilities of each party arrhythmia foods to avoid purchase zestril 10mg amex. If a written agreement is not feasible blood pressure medication overdose discount zestril 10mg overnight delivery, it is still important to lay out expectations and roles/responsibilities of each organization pulse pressure wave purchase cheapest zestril and zestril. Some common barriers or challenges include competing interests blood pressure medication heartburn purchase zestril 5mg free shipping, history of conflict between organizations arrhythmia effects generic 10 mg zestril overnight delivery, political or resource constraints arteria gallery buy zestril 10 mg low price, changing values or goals, lack of coordination or structure, and change in supportive staff and/or leadership Strategies to Overcome Barriers As the relationship begins, keep in mind the importance of communication and trust. The partnership manager should begin the relationship by listening to the organization and finding out what its mission and values are before making a request. Remembering to focus on the positive throughout the relationship and bring successes to each meeting. Ensuring that the partnership goals be considered at all times while also being flexible to changes that may occur at each organization. Keeping up-to-date information on each organization and providing it to school/ district staff. Scheduling regular meetings and professional development opportunities between organizations to share information, discuss available services, and assess the partnership. Key staff can learn more about each organization and focus on building relationships. Recognizing new organizations through a certificate of appreciation or other means to highlight the importance of their work and to thank them for their partnership. Connect with various school and district staff, as well as the organizations your district or school has partnered with, to ask them the set of questions below in order to collect information about how the partnership is going. How does this partnership support the goal of increasing youth access to sexual health servicesfi Use the worksheet below and the suggestions on page 27 of this document to strategize how you will overcome barriers with each organization. This would include setting goals and objectives, identifying data needed, establishing a timeframe, and seeking additional resources if necessary. Assessing organizational partnerships enables the two (or more) organizations to document successes, demonstrate accountability, measure effectiveness, and plan for the future. Beyond reviewing the intended outcomes, the organizations can also determine what is working or not working in the partnership, and if any changes are necessary. This information can be gathered during established meetings or through partner surveys. In addition to the key questions above, did the partnership include the following indicators of a successful collaborationfi The results of the partnership assessment can be used to identify any challenges and successes. If challenges persist or seem insurmountable, it may be time to terminate a partnership. If the partnership was successful, this can be used as a communication tool to showcase the work to the community and be used as a way to recruit new partners. This may allow for better access to sensitive services like sexual health services. A social worker and nurse provided in-school support and education through homeroom and classroom presentations, and a weekly presence in a school health-suite for individual counseling and small group discussions. Off school grounds, the social worker and nurse provided reproductive healthcare and services at the Self Center. Evaluation of the Self Center showed a positive impact on sexual debut, teen pregnancy rates, and contraceptive usage. Districts and schools in high prevalence areas may consider schoolbased screening programs when partnerships are strong and when capacity and interest are high. To that end, school nurses facilitate positive student responses to normal development; promote health and safety; intervene with actual and potential health problems; provide case management services; and actively collaborate with others to build student and family capacity for adaptation, self-management, self-advocacy, and learning. The certifications and educational background necessary to be a school nurse and their roles and duties differ across school systems. Chicago and Philadelphia public schools have similar programs in their high schools. The purpose of this Memorandum of understanding (Mou) is to create a framework for the partnership.

Provide student roster to ensure accurate recording of student name and date of birth on each specimen. Promote screening program to students, parents and staff, as appropriate, through promotional materials developed by the Medical Provider in consultation with key constituents. Provide space and storage (if needed) for education/screening session, specimen packaging, and treatment provision. Establish and implement a plan to distribute and collect parental notification of screening event. Tour event location to identify space for educational session, lab, specimen collection (bathrooms), volunteer area and results/treatment provision that ensures student confidentiality. Meet with select teachers and school staff to explain event, schedule, and impact on their time. If a minor is 12 years old or younger and sexually active, this is considered child abuse and would be reported as required by law. By law, the Medical Provider must report positive test results for chlamydia and gonorrhea to the local and state health department. The local health department may follow-up with patients to ensure proper treatment and partner management. This agreement may be updated at any time through written agreement of each party. Partnerships involve mutual respect, coordination of administrative responsibility, establishment of reciprocal roles, shared participation in decision-making, mutual accountability, and transparency. Professional development is consciously designed to actively engage learners and includes the planning, design, marketing, delivery, evaluation, and follow-up of professional development offerings (events, information sessions, and technical assistance). Youth-friendly services ensure confidentiality, respectful treatment, and delivery of culturally-appropriate care in an integrated fashion at no charge or low cost and are easy for youth to access.

These guidelines also aim to address the important public health aspects of infection control and antimicrobial stewardship. It must be emphasised that clinical guidelines present the best evidence available to the experts. However, following guideline recommendations will not necessarily result in the best outcome. Guidelines can never replace clinical expertise when making treatment decisions for individual patients, but rather help to focus decisions also taking personal values and preferences/individual circumstances of patients into account. These are abridged versions, which may require consultation together with the full text version. A total of 1,661, 640 and 2,657 unique records were identified, retrieved and screened for relevance for sections 3. Specific chapters were updated based on systematic reviews of topics or questions prioritised by the Guideline Panel. These reviews were performed using standard Cochrane systematic review methodology. The systematic review results for the following evidence question are included in the 2018 Urological Infections Guidelines: 1. What is the best antimicrobial prophylaxis strategy to reduce risk of infectious complication of prostate biopsy [3]fi For each recommendation within the guidelines there is an accompanying online strength rating form which addresses a number of key elements namely: 1. These key elements are the basis which panels use to define the strength rating of each recommendation. The strength of each recommendation is determined by the balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including certainty of estimates), and nature and variability of patient values and preferences. Urosepsis Urosepsis is defined as life threatening organ dysfunction caused by a disregulated host response to infection originating from the urinary tract and/or male genital organs [14]. In acute care hospitals, 20-50% of prescribed antibiotics are either unnecessary or inappropriate [17]. In response, a worldwide initiative seeks to incorporate Antimicrobial Stewardship programs in healthcare [18]. Antimicrobial Stewardship aims to optimise clinical outcomes and ensure cost-effective therapy whilst minimising unintended consequences of antimicrobial use such as healthcare associated infections including Clostridium difficile, toxicity, selection of virulent organisms and emergence of resistant bacterial strains [19]. The first set mandates use of recommended care at the patient level conforming to guidelines. The second set describes strategies to achieve adherence to the mandated guidance. These include persuasive actions such as education and feedback together with restricting availability linked to local formularies. A Cochrane review of effectiveness of interventions to improve antibiotic prescribing practices for hospital inpatients, updated in 2017, found high-certainty evidence that such interventions are effective in increasing adherence with antibiotic policy leading to reduced antibiotic treatment duration and may also reduce hospital stay. The review found no evidence that reduced antibiotic usage increased mortality [20]. A 2016 systematic review of evidence for effectiveness of various Antimicrobial Stewardship interventions in healthcare institutions identified 145 studies of nine Stewardship objectives.

Nerve conduction studies Measure amplitude hypertension medicines generic zestril 2.5mg line, latency pulse pressure 64 generic zestril 10 mg on-line, configuration, and conduction velocities of motor, sensory, or mixed nerves (Figure 2. Conduction velocity is dependent on the diameter and degree of myelination of the neuron. Patchy demyelination causes attenuation of the compound muscle action stimulated proximally but stimulation nearer the muscle (distal to the patchy demyelination) gives normal results. Asymmetry of response is key to determining abnormalities: under normal circumstances, latencies should not differ between sides by >1 ms. F-wave F-wave studies are used to assess the proximal segments of the motor nerve function, and are performed in combination with the examination of motor nerves. The response is then fired down along the axon and causes a minimal contraction of the muscle. Unlike the H-refiex, the F-wave is always preceded by a motor response and its amplitude is rather small, usually in the range of 0. Electrophysiologic correlates of peripheral nervous system maturation in infancy and childhood. Each potential is produced by groups of fibres responding to a single motor neuron. Appearances can be ambiguous, however, and it is important to interpret the findings in the light of other aspects of the clinical picture, the technical adequacy of the study and the experience of the neurophysiologist. These are sharp, bi-phasic and of short duration with low amplitude potentials of about 100 fiV. They indicate collateral re-innervation by surviving neurons with an increased territory. There are age-dependent normal values for jitter, measurement of which is expressed as mean consecutive difference or mean sorted difference between the trigger potential and an adjacent muscle fibre potential. The large recording surface picks up electrical activity from all muscle fibres from a single motor unit. Quantitative electromyography Motor unit morphology can be quantified by analysing the duration, amplitude, phases, turns, area or area/amplitude ratio for 20 or more randomly selected simple motor units from a given muscle. They are passive responses that can be elicited in the uncooperative (ill or young) child. As visual acuity returns, amplitude will improve but delayed latency is typically permanent. Temporary elevations may occur immediately after seizures but these tend to be modest. Urine organic acids Abnormal profiles may be present all the time or only during metabolic decompensation. Many substances may create artefactual changes including concomitant valproate administration. There is a risk of false negatives if urine is too dilute or the child has recovered from metabolic decompensation. Urine amino acids Analysis may be used to diagnose a metabolic defect or to monitor treatment of aminoacidurias. Urinary mucopolyand oligosaccharide screen Urine mucopolysaccharide screening tests uses 2-D electrophoresis to detect greatly elevated levels of glycosaminoglycans in mucopolysaccharidoses. Additionally, thin-layer chromatography is performed to identify the oligosaccharidoses (including mannosidosis and fucosidosis). Urine sulphites the presence of sulphites in urine indicates molybdenum cofactor or sulphite oxidase deficiency. There is a significant false negative risk if the sample is not tested within 20 min of voiding due to degradation of sulphites. Urine alpha-aminoadipic semialdehyde A-aminoadipic semialdehyde dehydrogenase deficiency causes pyridoxine dependent seizures. Urine creatinine, creatine, and guanidinoacetate Disorders of creatine metabolism may be suspected from a low serum creatinine concentration. Acidosis may accompany many metabolic conditions, notably mitochondrial cytopathies, organic acidopathies, and catabolic states. Either urine organic acids (in acute episodes) or acylglycines should be analysed. Ammonia Hyperammonaemia is an important indication of urea cycle disorders and/ or liver dysfunction; however, artefactually raised ammonia levels due to improper sample collection are common. Blood obtained should be free fiowing, and the laboratory forewarned to accept and promptly handle the sample, which should be transported on ice as red cells and glutamine in the serum can otherwise both also release ammonia. Many laboratories screen for a panel of enzymes; however, this may not include the enzyme you are specifically interested in! It is important that the laboratory has appropriate quality assurance procedures in place. This sample can be fixed and prepared for electron microscopy for inclusion bodies, which can be useful in the diagnosis of lysosomal disease and neuronal ceroid lipofuscinosis. A small number of acanthocytes may be seen in other forms of severe haemolytic anaemia, particularly after splenectomy. Lactate Free fiowing blood is typically collected immediately into perchloric acid to deproteinize it. For the laboratory to interpret the levels of the volume of added blood must be accurately known: this is usually done by pre-weighing the tube. Metaphase spreads are selected, and the chromosomes are arranged in descending order by size and compared with a standard. Techniques constantly improve in terms of the types of staining available, and the analysis is now often computerized. This often makes it worth repeating the test if it has not been done for some years. Comparative genome hybridization this technique is becoming increasingly available and may replace routine karyotyping in the near future. Balanced rearrangements, inversions or other rearrangements that do not alter total copy number will not be detected. Ring chromosome 20 mosaicism this is a recognized syndrome of severe epilepsy and learning difficulties with severe behavioural features. Ring chromosome 20 mosaicism should be specified if this is a consideration so that more cells are examined: examination of 50 cells will identify 6% mosaicism with 95% confidence. Stop and maintain the cuff for 1 min, then release the cuff, and take blood for lactate and ammonia at 2 and 12 min. Transferrin is a sensitive and convenient marker, secreted by the liver and normally present in different isoforms due to differences in glycosylation. Biotinidase the phenotypic range of this treatable deficiency state is broad (see b p. Consider testing especially where there is hypotonia, severe infantile epilepsy, alopecia, rashes, and hearing loss. Note: most specific enzyme assays can be carried out on cultured skin fibroblasts, cultured amniotic fiuid cells or chorionic villus samples. Whilst not specific, the diagnosis of a number of neurological conditions may be assisted by the demonstration at electron microscopy of inclusion bodies in apocrine sweat gland-containing skin. Establishment of fibroblast culture may be indicated for enzyme analysis to investigate inborn errors of metabolism or chromosome analysis to look for tissue specific mosaicism. Skin for fibroblast culture must be scrupulously sterile or contaminants will prevent the culture establishing. Take a small sample (a few millimetres in diameter) to prevent necrosis of the centre of a larger sample. For fibroblast culture collection into tissue culture medium is strongly preferred (use saline only exceptionally). Avoid iodinecontaining compounds such as betadine as these interfere with cell growth in culture. Although the technique is relatively simple, success depends on obtaining several samples of adequate size from a single insertion site. Subsequent specimen processing should only be done by laboratory technicians familiar with the techniques. Intrathecal medicine Inadvertent intrathecal injection of cytotoxics intended for intravenous use in the treatment of acute lymphoblastic leukaemia has been a repeated cause of medical tragedy. Intrathecal cytotoxics should only be given by paediatric oncologists in a dedicated setting. Shunt tap this should ideally only be performed by a neurosurgeon as different shunt designs have different access points and some are not suitable for tapping (Figure 2. Neuropsychological testing complements and supplements assessment by an educational psychologist. Visuospatial Visuospatial tests assess right hemisphere function predominantly, although a left hemisphere infiuence may be present if verbal mediation occurs. Visuomotor functioning Closely related to visual item perception and visuospatial processing, visuomotor functioning adds a manipulation or graphomotor component to the perceptual tasks. Social-emotional functions these are particularly important in children with non-verbal learning disabilities. Qualitative data (the types of errors produced) may be useful in determining context-related processing difficulties from executive function problems.

However attempts to argue, persuade, or cajole a child with an acute confusional state will be counter-productive. For example, the child with genetically-determined learning difficulties under pressure at school adopting strategies for task avoidance or attention seeking. Specific patterns Oppositional defiant disorder the child is often negative and defiant, with a frequent loss of temper; arguing or non-compliant with adults. The child may be angry and resentful, irritable and easily annoyed, and deliberately annoying other people. Conduct disorder the child shows a persistent tendency to transgress normally accepted rules or the rights of others. Attention deficit disorder A developmental disorder resulting in difficulty directing attention to tasks, listening to or following instructions, or organizing activities. Children exhibit distractibility, varying degrees of fidgetiness and impulsivity. Treatment with stimulant drugs (methylphenidate, atomoxetine) may be indicated; a behavioural approach with firm, consistent handling with the definition of boundaries of acceptable behaviour usually used first, particularly for the under 5s. This gives a profile of skills that can be compared with in the future, to see if development is static, progressing or regressing. Global impairment Causes A genetic or syndromic cause is typically identified in 720% of children investigated for global developmental impairment, in the absence of neurological (particularly motor) signs, regression, dysmorphism, family history, or other evidence of genetic causes. Investigations If no specific clues are found in the history, then the chances of finding a diagnosis are small. Otherwise, depending on severity of the delay, although subtle abnormalities are being increasingly found with high resolution scans. Specific motor delay/late walking this often presents as a child with delayed sitting or walking. As the child will usually be young, the motor problem usually predominates and delay in other areas (language, etc. Opportunistic observation of quality of movement in free play will often be more informative than attempted formal motor examination.

Male dogs often have cryptorchidism and bitches can sometimes show a persistent oestrus (Kooistra et al. Non-specific laboratory changes observed in canine hypothyroidism Finding a hypercholesterolemia and a non-regenerative anemia on a blood analysis can increase the suspicion for hypothyroidism. The animal has to be fasted for at least 12 hours before taking the sample in order to avoid postprandial hypercholesterolemia. The hypercholesterolemia is often pronounced in hypothyroid dogs with some dogs showing values in excess of 10 mmol/L. Unfortunately, hypercholesterolemia is observed in many other diseases such as hyperadrenocorticism, diabetes mellitus, glomerulopathies and liver diseases. Normocytic normochromic anemia is observed in 30% of dogs with hypothyroidism, but the packed cell volume typically remains above 25%. This anemia could be due to a decreased stimulation of erythropoiesis by erythropoietin and thyroid hormones. These are thought to be the result of cholesterol overload of the erythrocyte membrane (Feldman & Nelson, 1996). Thrombocytosis can be observed and platelets are sometimes smaller (Sullivan et al. A few years ago, it was thought that hypothyroidism could lead to a decrease in von Willebrandfactor and bleeding tendencies. Recent studies have however shown that this was not the case (Panciera & Johnson, 1994). Frequently, the dermatological abnormalities observed suggest an endocrine origin but are seldom specific for hypothyroidism. Cutaneous changes that would support a diagnosis of hypothyroidism, are hypertrophy and a vacuolisation of the musculi erectori around the hair follicle (controversial), dermal mucinosis and a thickening of the dermis with the presence of myxoedema (Miller & Dunstan, 1993; Scott et al. Specific thyroid tests used in dogs Because of the vague clinical signs and the absence of specific abnormalities on a routine blood test, the diagnosis should be confirmed through a specific evaluation of the thyroid gland. It is indeed important to mention that the positive predictive value of a diagnostic test increases when the prevalence of the disease increases. A thorough clinical examination of the patient, knowledge of the advantages and disadvantages of all available tests and knowledge of the factors that can influence the results, will allow the veterinarian to correctly diagnose the disease. Table 2 contains a summary of the advantages and disadvantages of the most commonly used thyroid hormone tests in dogs. Accuracy is the percentage of cases that are neither falsely positive nor falsely negative. Thyroid hormones kept in plastic tubes, remain stable for 5 days at room temperature, and can be kept frozen for years. Free thyroxine Only the free fraction of T4 (not bound to transport proteins) can enter the cells, link to the receptors and lead to a biological effect. However there is an important overlap between values observed in euthyroid dogs, hypothyroid dogs and dogs suffering from a systemic illness. For all those reasons, this test is seldom used in practice in the evaluation of thyroid function in dogs. Antibodies against thyroid hormones Antibodies against thyroid hormones can sometimes by found in dogs. Therefore, finding those antibodies suggests the presence of a lymphocytic thyroiditis. However, the presence of these antibodies does not reflect thyroid function, as 75% of the thyroid gland must be destroyed in order to lead to decreased T4 blood levels. Furthermore, anti-T3 and anti-T4 antibodies are only observed in approximately 30% of the hypothyroid dogs. These antibodies can interfere with radioimmunoassay determination of T3 or T4, and lead to falsely increased values as a consequence. More reliable measurement methods and interpretation criteria were recently published. The presence of antibodies in combination with normal thyroid hormone values can be an indication that hypothyroidism might develop. Diagnostic therapy Response to therapy as a sole method of diagnosing hypothyroidism is not recommended for several reasons. Even if the primary complaints improve with the administration of synthetic thyroid hormones, many intermittent disorders will improve with the administration of thyroid hormones. The consequence will be an unnecessary and expensive therapy, potential side effects or the delay in the diagnosis of the real problem. Scintigraphy Scintigraphy is a very useful method for evaluation of thyroid function. It is more commonly used in the evaluation of feline hyperthyroidism than in the evaluation of canine hypothyroidism. Unfortunately, because of the need for specialised equipment and the use of radioactive products, it is not widely available. Influence on thyroid function tests Numerous diseases and medications can influence thyroid function. Besides this, many other physiological factors such as, age, breed and fluctuating serum concentrations can influence the results. Therefore the interpretation of the laboratory result alone will lead to overdiagnosis of hypothyroidism. In puppies younger than 6 weeks of age, thyroid hormone serum concentrations are 2 to 5 times higher than in adult dogs. The exact cause for these differences in thyroid hormone levels with age is unknown, but highlights the importance of having specific reference values for each age category. Thyroid function test results in this breed should therefore be interpreted very cautiously (Gaughan & Bruyette, 2001). If some other breeds could have decreased thyroid hormone concentrations remains to be studied. Globally, there are no differences in thyroid hormone concentrations between male and female dogs. Daily random fluctuations in thyroid hormone concentrations have been described in euthyroid dogs (Miller et al. A pronounced protein deficit and fasting can decrease thyroid hormone values, but the influence of obesity has not yet been well documented in dogs and will be evaluated in chapter 5 (van Haasteren et al. Effects of drugs on canine thyroid function Table 4 shows drugs affecting thyroid function in humans with some proposed mechanisms of action. The symbols, =, indicate that the measurements may be increased, decreased or unchanged, respectively. As glucocorticoids are very commonly used in canine medicine, the potential effects of exogenous corticosteroid administration on canine thyroid function test results will be further evaluated in chapter 2. Phenobarbital In rats, phenobarbital markedly alters thyroid function by increasing the rate of clearance of T4. Increased hepatic deiodination of thyroid hormones, biliary clearance, and fecal excretion result in decreased concentrations of circulating thyroid hormones. Increased conversion of T4 to T3 in peripheral tissues also may play a role (Gieger et al. Further complicating the clinical evaluation of a dog tested for hypothyroidism and administered phenobarbital, is that weight gain (due to polyphagia), lethargy and hypercholesterolemia are reported in dogs on phenobarbital treatment, but are also commonly observed in dogs with hypothyroidism (Chrisman, 1991; Scott-Moncrieff & Guptill-Yoran, 2000; Gieger et al. Potassium bromide For years, phenobarbital has been considered the most effective initial treatment for dogs with epilepsy (Chrisman, 1991). Bromide is a halide chemically related to iodide and potentially could interact with iodine in the thyroid gland. In rats, bromide produces a relative iodine deficiency, thereby interfering with iodine uptake, iodine transport and iodination of tyrosine and tyrosyl residues on thyroglobulin (Velicky et al. Some of these effects already were noticed in thyroid glands of rats with small dosages of bromide. Sulfonamides Sulfonamides can markedly interfere with thyroid hormone synthesis in rats by reversible inhibition of thyroid peroxidase, an enzyme essential for iodination (Comby et al. Sulfonamides therefore are goitrogens, leading secondarily to diminished thyroid hormone synthesis and secretion. Considerable interspecies variation however exists with respect to thyroid peroxidase inhibition by sulfonamides (Doerge & Decker, 1994; Capen, 1994). For example, only mild effects of sulfonamides are observed on human thyroid function (Cohen et al. When a combination of sulfonamides and trimethoprim is used, it is the sulfonamide component which is responsible for thyroid inhibition, and trimethoprim alone failed to cause detectable alteration of thyroid function in rats (Cohen et al. Several prospective studies have evaluated the effects of sulfonamide administration on thyroid function in dogs. When trimethoprim-sulfadiazine was administered in the second half of gestation to pregnant bitches, no effects were noticed on thyroid hormone concentrations or thyroid gland morphology in the newborn puppies (Post et al. Furthermore, radionuclide thyroid imaging showed increased uptake of pertechnetate, and thyroid gland biopsies disclosed hyperplasia of thyroid follicles and absence of colloid production (Campbell et al. Clearly, the effects of sulfonamides on thyroid function are species-specific, and dosageand duration-dependent. Normalization of thyroid function test results in dogs after cessation of sulfonamide administration can take 8 to12 weeks. If the clinician is not aware of the effects of sulfonamides on thyroid function, an inappropriate diagnosis of hypothyroidism can easily be made in a dog receiving sulfonamides. Not only can sulfonamides alter thyroid function test results, but they also can lead to clinical hypothyroidism in some dogs. The dogs described in these 2 papers received a dosage of 24 mg/kg of trimethoprim-sulfadiazine for periods ranging from 30 to 126 days. Thyroid scintigraphy was helpful in distinguishing endogenous from sulfonamide-induced hypothyroidism in one report (Gookin et al. These effects are most important in humans treated with salicylates, fenclofenac and phenylbutazone (Davies & Franklyn, 1991). For example, administration of a single dose of aspirin acutely increases free thyroid hormone concentrations by 2to 3-fold (Larsen, 1972). During long-term treatment with salicylates, a new steady state is reached reflecting increased T4 turnover rate (Davies & Franklyn, 1991). Free T4 concentrations can be unchanged or decreased (Surks & Stievert, 1995; McConnell, 1999). Thyrotropin concentrations return to the reference range within a few weeks of treatment (McConnell, 1992). The contribution of these disturbances on peripheral thyroid hormone metabolism however is uncertain (McConnell, 1999). These results may be explained by the fact that, in humans, T3 is less avidly bound to transport proteins and is more easily displaced than T4 (Carlson et al. Thyroid hormone binding to serum carrier proteins and hormone metabolic rates vary among species. Affinity of thyroid hormones for their serum proteins is lower in dogs than in humans (Larsson et al. Propranolol does not seem to significantly affect serum thyroid hormone concentrations in dogs. These changes probably reflect a physiological adaptation of the organism leading to a decrease in tissue energy requirements. The administration of synthetic thyroid hormones to these patients is not recommended. Free T4 can also be decreased but often to a lesser extend (Scott-Moncrieff & Guptill-Yoran, 2000). Diagnostic approach Diagram 1 gives a possible approach for a patient suspected of having hypothyroidism. Treatment of canine hypothyroidism Treatment of hypothyroidism consists in life long administration of synthetic levothyroxine (L-T4) in order to: approximate the secretion of thyroid hormones by the thyroid gland, resolve clinical signs and avoid thyrotoxicosis. A normal thyroid gland secretes principally T4, which is thereafter transformed in T3 through peripheral deiodination. The administration of a medication containing T3 and T4 is contraindicated because both hormones have very different half-times and in consequence their frequency of administration is very different. Treatment with liothyronine T3 is also contraindicated because it should be administered 3 times a day and more easily lead to thyrotoxicosis, presumably because the organism cannot regulate deiodination of T4 into T3. The use of an original preparation ("brandname"), and a veterinary preparation should be prioritised, because biological availability of generic or human products varies in dogs (Nachreiner & Refsal, 1992). In dogs, fecal excretion is higher and intestinal reabsorption less (10-50% compared to 50-80% in humans) (Ferguson, 1986). Initial treatment dosages varies from 11 to 22 Pg/kg q 12 hour according to the author, with a maximum of 0,8 mg of L-thyroxine q 12 hour (Rijnberk, 1996; Greco, 2000; ScottMoncrieff & Guptill-Yoran, 2000). The patient is revaluated 1 to 2 months after initiating therapy and dosage is adjusted based on clinical response and results of the T4 serum concentration. The pharmacokinetics of levothyroxine after oral administration varies from patient to patient, therefore an individual adjustment of the dosage is needed (Nachreiner et al. If the owner or veterinarian wishes to use generic products, revaluation of serum concentrations is recommended 1 to 2 months later. Hair regrowth will be more progressive, but an improvement should be noticed within 4-6 weeks. When a blood sample is taken just before administration of the medication (pre-tablet test), nadir concentrations are measured. Most commonly blood is taken 4 to 6 hours after the last medication is administered (post-tablet test) and peak concentrations are measured. In humans and in dogs, the administration of an excess of levothyroxine can lead to thyrotoxicosis. In human medicine, a small overdosage (subclinical thyrotoxicosis) can already lead to more hidden, but serious complications such as osteoporosis, increased liver enzymes or an occult cardiac hypertrophy (Greco, 2000). On the contrary, dogs only seldom suffer from clinical thyrotoxicosis (polyuria/polydipsia, polyphagia, weight loss, panting, hyperactivity). This is probably related to the more rapid elimination of thyroid hormones in dogs compared to humans. It is not clear whether the dog can, as observed in humans, suffer from subclinical thyrotoxicosis with side effect noted on the mid to long term. But it does not allow to differentiate an over treated dog from a well-controlled dog. Conclusion Treatment of hypothyroidism is relatively simple, but obtaining a reliable diagnosis can sometimes be more difficult. Knowledge of these factors can contribute to decreasing the misdiagnosis of hypothyroidism. Non-thyroidal diseases and the administration of medications can lead to decreased thyroid hormone concentrations.
