With the majority of evidence being submitted involving sexual assaults, it Received in revised form is important to have conrmatory tests for the identication of semen that are straightforward, quick, 3 September 2013 and reliable. These kits were assessed with aged semen stains, fresh and frozen post-vasectomy semen, post coital samples collected on different substrates, post-vasectomy semen mixed with blood, saliva, and Keywords: Forensic serology urine, a series of swabs collected at increasing time intervals after sexual intercourse, and multiple non p30 semen samples. The test kits were compared on the basis of sensitivity, specicity, and the cost and time Post-coital effectiveness of each protocol. These types of results may be seen in addition to the cost and time effectiveness of each protocol. The semen samples consisted of post vasectomy samples obtained from a medical laboratory.

Given the high prevalence of hypertension, researchers have begun to explore the relationship between hypertensive disease and male fertility. The current literature suggests an association between hypertension and semen quality. The use of various antihypertensive medications has also been linked to impaired semen parameters, making it difficult to discern whether the association exists with hypertension or its treatment. Further investigation is warranted to determine whether the observed associations are causal. Despite this, the relationship between hyper the average age of paternity is rising in America. For example, several groups as men age, they are more prone to develop chronic have highlighted a collection of studies that suggested an illnesses. Considering the link between several medical association between infertility and obesity/high body diseases and impaired semen quality [2], it is important to mass index, diabetes, and dyslipidemia [5-8]. Ventimiglia investigate the potential impact of chronic illness on male et al [9] explored the association between medical co fertility. Not surprisingly, the use of prescription anti erature regarding hypertension in isolation, or its treat hypertensive medications is also common. Abnormal semen parameters Rare studies have linked hypertension to some aspects were defined based on the World Health Organization of sperm physiology. In addition, an medications were only included if taken in the year prior Italian group found higher levels of clusterin, a glyco to the semen analysis. These studies were small in scale and ex chi-square for age group and year of evaluation. All semen tests were square-root-trans the association between hypertension and semen quality. For the ratory performs a high volume of semen analyses for fertil comparisons between men who took diuretics and those ity evaluation and sperm preparations for use with assisted who did not, the Wilcoxon rank-sum test was also applied reproductive techniques. All p-values were two-sided, were self-referred, or were referred by an internist, gyne with p<0. Moreover, compared to men without Board, the assembled cohort was linked to insurance hypertension, men diagnosed with hypertension demon claims and electronic medical record data for each patient strated impaired semen parameters [15]. For antihypertensive medications, we classified prevalence of men with hypertension had subfertile se them into five categories: beta beta-blockers, calcium men volume (18. In addition, antihypertensive medication and 45 were taking 2 or higher rates of certain types of cancers have also been re more antihypertensive medications.

Importantly, a higher incidence of hypertension was not We then stratified men by individual class of anti identified in this group, suggesting that male infertility is hypertensive medication [15].

Men taking angiotensin-receptor blockers had rel hypertension have a lower semen volume, sperm motility, atively increased volume and decreased sperm concentra total sperm count, and motile sperm count relative to men tion. Importantly, more men with a diagnosis of hyper relatively decreased volume (Table 2). Moreover, the use of be ta-blockers was associated with lower semen volume, Infertility may be a harbinger of health. The direct end-organ effects of hypertension on the ar teries and kidneys have been studied in depth, but the ef fect on the testes is not well characterized. Prior research has addressed the relationship between hypertension and the endocrine axis, which may affect reproductive ability. For example, in a cross-sectional study of 1,548 men, Svartberg et al [23] demonstrated an inverse association between total testosterone level and systolic blood pressure. In a case-control study of 110 newly diagnosed hypertensive men, Fogari et al [24] showed a 10% reduc tion in total testosterone levels compared to normotensive men. However, given study design, causal pathways be tween hypertension and testicular function cannot be inferred. While the etiology of the association between hyper tension and semen quality remains unknown, the relation ship between somatic health and semen production has been reported [9,24,25]. For example, the fetal origins of dis ease theory posits a common in utero exposure could lead to both infertility and hypertension [26-28]. The current report identified multiple ab normalities associated with beta-blockers but not other in dividual classes of antihypertensives. This is particularly relevant given that beta-blockers represent one of the most commonly medications prescribed, with over 85. Importantly, several medications have been investi gated previously for their impact on fertility. For example, retrograde ejaculation is known to be a common side ef fect of alpha-blockers and consequently would decrease semen volume [29]. Thus, the non-selective alpha-blocker phenoxybenzamine was investigated as a male oral con traceptive in the 1980s [30]. In addition, a case report documented a pregnancy for an infertile couple following the discontinuation of the calcium channel-blocker nifidi pine [31]. An in vitro study suggested that certain receptors for normal acrosomal reaction were reversibly impaired by calcium-channel blockers [32].

Cumulative concussion expo sure in rugby players: Neurocognitive and symptomatic outcomes. Without question, a post-concussion syndrome can be worsened by psychological distress, social psychological factors. If due to the neurobio logical effects of an injury to the brain, a post-concussion syndrome should be pres ent in the first week post injury. Evaluating someone long after an injury, obtaining a cross-section of symptoms, and then attributing those symptoms to the remote injury can easily result in misdiagnosis. However, it is well established that these symptoms could be caused, main tained, or worsened by a large number of factors that are unrelated to traumatically induced cellular damage. It is emphasized in this chapter that the post-concussion syndrome is a non-specific cluster of symptoms that can be mimicked by a number of pre-existing G. The biologically-based, traumatically-induced syndrome, theoretically, can also occur in tandem with these conditions. However, the post concussion syndrome is a non-specific cluster of symptoms that can be mimicked by a number of pre-existing or co-morbid conditions. A more biologically-based, traumatically-induced syndrome, theoretically, also can occur in tandem with these conditions. These symptoms may be accompanied by feelings of depression or anxiety, resulting from some loss of self-esteem and fear of permanent brain damage. Some patients become hypochondriacal, embark on a search for diagnosis and cure, and may adopt a permanent sick role. The etiology of these symptoms is not always clear, and both organic and psychological factors have been proposed to account for them. There is little doubt, however, that this syndrome is common and distressing to the patient. Diagnostic Guidelines: At least three of the features described above should be present for a definite diagnosis. Careful evaluation with laboratory techniques (electroencephalography, brain stem evoked potentials, brain imaging, oculonystagmography) may yield objective evidence to substantiate the symptoms but results are often negative. The person must also report three or more subjective symp toms, present for at least 3 months, from the list below. If the syndrome/disorder is clearly documented in the initial weeks post-injury and continues, with only modest improvement over many months, then causation is more clear. However, it is frequently the case that the original severity of injury, acute symptoms in the first week post-injury, and recovery course cannot be determined. In fact, the etiology of the persistent post-concussion syndrome has never been agreed upon (see Bigler 2008; Evered et al. For decades, the validity of this diagnosis as a true syndrome or disorder has been questioned. Most researchers suggest that the post concussion syndrome is the result of the biological effects of the injury, psychological factors, psychosocial factors (broadly defined), chronic pain, or a combination of factors (Bijur et al. Researchers have reported that healthy adults and the clinical groups listed below report very similar symptoms. The challenge for the clinician is to determine whether these self reported, non-specific, symptoms are related or unrelated to the injury. Common clinical conditions include traumatic cervical injuries due to whiplash-associated disorders; chronic pain, particularly headache and neck pain; depression; and the anxiety spectrum disorders (including post-traumatic stress disorder). Patients with these conditions often report physical, cognitive, and psychological symptoms. Personality Characteristics and Disorders Personality characteristics influence how people respond to illness, injury, or disease. Some individuals tend to over-emphasize cognitive and physical symptoms, whereas others tend to de emphasize them. A certain symptom might be overwhelming for one person, yet another person may see this same symptom as simply slightly annoying. Often this takes the form of being vulnerable and unprotected, of not being responded to when hurt or sick, or of not being able to gain retribution when one has been wronged. These include: (1) over achievement, (2) dependency, (3) insecurity, (4) grandiosity, and (5) borderline personality characteristics (not disorder). Although poorly understood, there is little doubt that personality characteristics influence the development and maintenance of the post-concussion syndrome. Other researchers have reported similar, although not identical, results (Ferguson et al. Gunstad and Suhr (2001) empha sized the importance of appreciating a more generalized expectation of negative outcome regardless of the event. That is, the sickness is, essentially, caused by expectation of sickness (Hahn 1997). Researchers have reported that litigants tend to exhibit a response bias in symptom recall compared to non-litigants. That is, personal injury litigants without a history of head trauma, compared to non-litigants, tend to report better past levels of functioning in life in general, self-esteem, concentration, and memory; and fewer symptoms of depression, anxiety, irritability, and fatigue than general medical patients. Stereotype Threat and Diagnosis Threat Social psychology researchers have been interested in the concept of stereotype threat for many years to help explain performance differences between certain groups. For example, Asian-Americans perform better than Caucasians in mathematics, or men perform better than women at using a map to navigate. Suhr and Gunstad (2002) adopted this concept and applied it to the neuropsy chological literature by proposing the concept of diagnosis threat. In two studies, Suhr and Gunstad 2002, 2005 found that participants who were provided with information highlighting the expected cognitive deficits associated with a mild brain injury. Iatrogenesis: A state of ill health or adverse effect caused by medical treatment. Telling her she has brain damage and she will need to cope and compensate, when in fact the probability of permanent brain damage was very low and the probability of an anxiety disorder and sleep disturbance was high, can be iatrogenic. It can also, of course, result in failure to provide the most effective treatment. Nocebo effect: Causation of sickness by the expectations of sickness and by associated emotional factors. Checklists and questionnaires are widely used to document post-concus sion symptoms. One concern, however, is that the use of these measures might lead to the over-endorsement of symptoms and problems. The sample consisted of 61 patients consecutively referred for an intake assessment or neurop sychological evaluation over a 27-month period (mean age = 40. The patients were initially asked during a clinical interview to identify the symp toms and problems they had been experiencing over the past couple of weeks. Patients were encouraged to provide a comprehensive list of symptoms and prob lems during the interview. However, when given the questionnaire to complete, they endorsed the presence of 9. Participants reported a sig nificantly greater number of symptoms when responding to a list of symptoms. In addition, there was little similarity in the symptoms reported using each method. Participants consistently reported a higher number of somatic, cognitive, emotional, and pain related symp toms when elicited using a symptom checklist compared to volunteered recall. There are multiple reasons why patients report far more symptoms on a question naire than during the interview. For example, the questionnaire (1) might remind the patient of a symptom, or (2) encourage the patient to report a symptom that he or she did not think was of interest to the clinician. Moreover, some patients are not very good at articulating their symptoms and problems during an interview, and anxiety 754 G. There are also several reasons, however, to question the validity of questionnaire results. For example, clinicians need to be aware of the possibility of (1) non-specific symptom endorsement. Moreover, patients periodically do not understand the meaning of a symptom, do not ask for clarification, and simply endorse it. It is also fairly common for patients to report past symptoms as if they are current symptoms. Without due consideration of these factors, clinicians and researchers may misattribute a poor performance on testing to an underlying deficit when, in fact, the individual has simply failed to give adequate effort. In 2005, the National Academy of Neuropsychology published a position paper on the need for symptom validity assessment in neuropsychological practice (Bush et al. This position paper solidifies the recommendation for routine effort and validity testing made by clinical researchers for many years. Specific guidelines for identifying malingering in a neuropsychological evaluation have been available for several years (Slick et al. It is important to appreciate poor effort during testing and exaggeration of symp toms are separate behavioral constructs. Poor effort on testing may or may not occur with obvious exaggeration of symptoms and problems, and vice versa (Boone et al. We prefer using the terms poor effort for describing under-performing on neuropsychological tests, and exaggeration for describing over-reported symptoms. Clinicians should be encouraged to conceptualize poor effort, exaggeration, and malingering not in simplistic dichotomous terms, but through probabilistic consid erations. A continuum for conceptualizing effort is as follows: defi nite poor effort, very likely poor effort, probable poor effort, adequate or good effort, very good effort, and exceptional effort. The accuracy of symptom reporting 24 Post-Concussion Syndrome 755 also falls on a continuum: under-endorsement, accurate reporting, possible exaggeration, probable exaggeration, definite exaggeration. It would be a mistake to conclude that a person provided good effort on the basis of performing normally on a single effort test.

Blast injuries are due to over-pressurization and are common within the lungs infection under fingernail buy discount erythromycin on line, ears antimicrobial nail solution erythromycin 250 mg overnight delivery, abdomen and brain antibiotics for acne and birth control purchase erythromycin 500mg line. The blast effect to the lungs is the most common fatal injury in those who survive the initial insult. These injuries are often associated with the triad of apnea, bradycardia, and hypotension, and suggested by dyspnea, cough, hemoptysis, and chest pain. The chest X-ray may have a butterfy pattern, an important indicators of blast lung. The patient may have clinical symptoms of blast lung injury immediately or clinical problems may not present for 24-48 hours post explosion. Tympanic membranes may rupture from overpressure; treatment here is also supportive. Intra-abdominal organs can receive injury from the pressure wave, and should be treated as any blunt abdominal injury. Lastly, brain injury is thought to be common in blast over pressure (shock wave). Burns are a common manifestation of signifcant blast injuries; these injuries are associated with the ball of fame with a potential for clothing ignition to extend the injury. Appendix 3, Radiation Injury, provides basic information on radiation burns and their management. Cold Injuries Cold injuries are frequently referred to a Burn Center for defnitive care. Also, covering all burn wounds prevents air currents from causing pain in sensitive partial thickness burns. The ensuing chapters in this manual will provide additional information on wound care and special issues in the management of electrical and chemical injuries. Defnition of a Burn Center A burn center is a service capability based in a hospital that has made the institutional commitment to care for burn patients. A multidisciplinary team of professionals staffs the burn center with specialized expertise, which includes both acute care and rehabilitation. The burn team also provides burn educational programs to external health care providers and is involved in research related to burn injury. Referral Criteria the American Burn Association has identifed the following injuries that should be referred to a specialized burn facility after initial assessment and stabilization at a referring facility. Burn injury in patients with preexisting medical disorders that could complicate management, prolong recovery, or affect mortality. In such cases, if the trauma pose the greater immediate risk, the patient may be stabilized initially in a trauma center before being transferred to a Burn Center. Burn injury in patients who will require special social, emotional or rehabilitative intervention. Health care providers must be able to assess the injuries rapidly and develop a priority-based plan of care based on primary and secondary survey elements. The plan of care is determined by the type, extent, and depth of burn, as well as by available resources. Every health care provider must know how and when to contact the closest specialized burn care facility/Burn Center.

Burn teams and burn centers: the importance of a comprehensive team approach to burn care. Any patients with burns and concomitant trauma (such as fractures) in which the burn injury poses the greatest risk of morbidity or mortality.

Physician judgment will be necessary in such situations and should be in concert with the regional medical control plan and triage protocols. Burned children in hospitals without qualifed personnel or equipment for the care of children. The severity of the injury is related to the temperature, composition, and length of exposure to the inhaled agent(s). A signifcant number of fre-related deaths are not due to the skin burn, but to the toxic effects of the by-products of combustion (airborne particles). In those with both a skin burn and inhalation injury, fuid resuscitation may increase upper airway edema and cause early respiratory distress and asphyxiation. Early intubation to maintain a patent airway in these individuals may be necessary. The combination of a signifcant skin burn and inhalation injury places individuals of all ages (pediatric, adult, and seniors) at greater risk for death. When present, inhalation injury increases mortality above that predicted on the basis of age and burn size. For instance, victims of house fres may exhibit symptoms of carbon monoxide poisoning, upper airway and lower airway injuries at the same time. It is also important to note that early respiratory distress in a patient with a skin burn may be due to a problem other than inhalation injury. Always consider the mechanism of injury and assess for the possibility of other traumatic or medical causes. Carbon Monoxide Most fatalities occurring at a fre scene are due to asphyxiation and/or carbon monoxide poisoning. Carbon monoxide is an odorless, tasteless, nonirritating gas that is produced by incomplete combustion. Among survivors with severe inhalation injury, carbon monoxide poisoning can be the most immediate threat to life. Carbon monoxide binds to hemoglobin with an affnity 200 times greater than oxygen. Oxygen delivery to the tissues is compromised because of the reduced oxygen carrying capacity of the hemoglobin in the blood. Carboxyhemoglobin levels of 5-10% are often found in smokers and in people exposed to heavy traffc. At levels of 15-40%, the patient may present with various changes in central nervous system function or complaints of headache, fu-like symptoms, nausea and vomiting. At levels > 40%, the patient may have loss of consciousness, seizures, Cheyne-Stokes respirations and death. In fact, patients with severe carbon monoxide poisoning may have no other signifcant fndings on initial physical and laboratory exam. Although the O2 content of blood is reduced, the amount of oxygen dissolved in the plasma (PaO2) is unaffected by carbon monoxide poisoning. Pulse oximeter readings are normal because an oximeter does not directly measure carbon monoxide. Late effects of carbon monoxide poisoning include increased cerebral edema that may result in cerebral herniation and death. Hydrogen Cyanide Hydrogen cyanide is another product of incomplete combustion that may be inhaled in enclosed space fres. It occurs primarily from the combustion of synthetic products such as carpeting, plastics, upholstered furniture, vinyl and draperies. Cyanide ions enter cells and primarily inhibit mitochondrial cytochrome oxidase (oxidative phosphorylation). Cyanide toxicity symptoms can be vague and diffcult to distinguish from other life-threatening issues. Cardiovascular symptoms feature a hyperdynamic phase followed by cardiac failure (hypotension, bradycardia). In a patient with smoke inhalation, lactic acidosis that remains unexplained despite resuscitation suggests cyanide toxicity. Inhalation Injury Above the Glottis True thermal burns to the respiratory tract are limited to the airway above the glottis (supraglottic region) including the nasopharynx, oropharynx, and larynx. The rare exceptions include pressurized steam inhalation, or explosions with high concentrations of oxygen/fammable gases under pressure. Heat damage of the pharynx is often severe enough to produce upper airway obstruction, and may cause obstruction at any time during the resuscitation period. In unresuscitated patients, supraglottic edema may be delayed at onset until fuid resuscitation is well underway. Early intubation is preferred because the ensuing edema may obliterate the landmarks needed for successful intubation. Supraglottic edema may occur without direct thermal injury to the airway but secondary to the fuid shifts associated with the burn injury and resuscitation. Inhalation Injury Below the Glottis In contrast to injuries above the glottis, subglottic injury is almost always chemical. Noxious chemicals (aldehydes, sulfur oxides, phosgenes) are present in smoke particles and cause a chemical injury, damaging the epithelium of the airways. Smaller airways and terminal bronchi are usually affected by prolonged exposure to smoke with smaller particles. However, it must be noted that the severity of inhalation injury and the extent of damage are clinically unpredictable based on the history and initial examination. While inhalation injury below the glottis without signifcant associated skin burns has a relatively good prognosis, the presence of inhalation injury markedly worsens prognosis of skin burns, especially if the burn is large and the onset of respiratory distress occurs in the frst few hours post injury. An asymptomatic patient with suspected lower airway inhalation injury should be observed given the variable onset of respiratory symptoms. Mucosal epithelial sloughing may occur as late as 4-5 days following an inhalation injury. Careful patient monitoring during resuscitation is necessary with inhalation injury. Excessive or insuffcient resuscitation may lead to pulmonary and other complications. In patients with combined inhalation and skin burns, total fuids administered may exceed predicted resuscitation volumes based on the extent of the skin burns. Oxygen Therapy and Initial Airway Management the goals of airway management during the frst 24 hours are to maintain airway patency and adequate oxygenation and ventilation while avoiding the use of agents that may complicate subsequent care (steroids) and development of ventilator-induced lung injury (high tidal volumes). Frequent and adequate suctioning is necessary to prevent occlusion of the airway and endotracheal tube. Factors to Consider When Deciding Whether or Not to Intubate a Patient with Burns the decision to intubate a burn patient is critical. Intubation is indicated if upper airway patency is threatened, gas exchange or lung mechanics inadequate, or airway protection compromised by mental status. Also, if there is concern for progressive edema during transport to a burn center, intubation prior to transport should be strongly considered. Stridor or raspy breath sounds may indicate impending upper airway obstruction and mandate emergency endotracheal intubation. For instance, many patients with superfcial partial-thickness facial burns, singed facial and nasal hairs, and fash burns from home oxygen are frequently intubated when they can be simply observed. Orotracheal intubation using a cuffed endotracheal tube is the preferred route of intubation. In children, cuffed endotracheal tubes are also preferred using an age-appropriate size. In instances where non-burn trauma mandates cervical spine protection (falls, motor vehicle collisions), cervical spine stabilization is critical during intubation. In impending airway obstruction, X-ray clearance of the cervical spine should wait until after intubation. An endotracheal tube that becomes dislodged may be impossible to replace due to obstruction of the upper airway by edema. Adhesive tape adheres poorly to the burned face; therefore, secure the tube with ties passed around the head or use commercially available devices. Do not place ties across the ears in order to prevent additional tissue damage and potential loss of cartilage. Because facial swelling and edema may distort the normal upper airway anatomy, intubation may be diffcult and should be performed by the most experienced individual available. Rarely is emergency cricothyroidotomy (incision made through the skin and cricothyroid membrane) required to establish a patent airway. General Assessment Findings the possible presence of inhalation injury is an important element in hospital transfer decisions. Normal oxygenation and a normal chest x-ray on admission to the hospital do not exclude the diagnosis of inhalation injury. The purpose of an initial chest x-ray is to verify that there are no other injuries such as a pneumothorax, and to verify the position of the endotracheal tube, if present. After adequate airway, ventilation, and oxygenation are assured, assessment may proceed with less urgency. Transfer to defnitive care should not be delayed for purpose of diagnostic testing. Carbon Monoxide Poisoning the half-life of carbon monoxide in the blood is about 4 hours for patients breathing room air and is decreased to about 1 hour when breathing 100% oxygen. Hyperbaric oxygen for carbon monoxide poisoning has not been shown to improve survival rates or to decrease late neurologic sequelae.

This anxiety can worsen the intensity of the symptoms, creating a vicious cycle and possibly leading to a panic attack. Both generalized anxiety and obsessive-compulsive disorder can become worse as a result of dopaminergic agents, particularly the dopamine agonists. Of course, adjusting your medication schedule should always be discussed with your physician. Buspirone (Buspar) is also particularly effective in treating generalized anxiety. Benzodiazepines are a popular and effective class of anti-anxiety drugs that can be potent in reducing symptoms of panic and worry. At times they can even help to control tremor in anxious patients by reversing the negative effects of anxiety that can cause tremor to worsen. Each of the approved benzodiazepines has different practical advantages, including duration of action, so the appropriate medication should be chosen based on frequency and severity of symptoms. For example, longer-acting benefit may be achieved with clonazepam (Klonopin) or lorazepam (Ativan) than with alprazolam (Xanax). A host of effective, non-pharmacologic techniques are readily available for treating anxiety including psychotherapy, behavior modification, biofeedback, meditation, massage, yoga, exercise, acupuncture and more. The prescribed dosage by your doctor and your effective dose may vary from dosages listed. These alterations in thinking ability fall on a broad spectrum from mild cognitive impairment to severe dementia. Fluctuating awareness refers to periods of mental clarity alternating with periods of confusion, distractibility, sleepiness and psychosis (usually visual hallucinations). The main difference in making the diagnosis is the timing of significant impairments in thinking in relation to the motor symptoms. A similar evaluation should be done if the change is more gradual and chronic, but the likelihood of finding a reversible cause of dementia is less than in the acute setting. It is commonly used in combination with donepezil, although the results of treatment are often disappointing. These are more commonly seen in patients who develop dementia in the late stages of disease. Visual hallucinations often involve scenes of people, animals or insects, while people with paranoid delusions may suspect that someone is plotting to do something harmful or that their spouse is unfaithful. Your healthcare team will want to assess and treat hallucinations and psychosis using the following guidelines: 1) Fully characterize the behavior. Does the problem pose a physical, emotional or financial threat to you or your family Has your memory, personality and/or concentration been changing (implying worsening dementia in addition to the psychosis) For example, are there any signs of infection such as fever, cough, painful urination or diarrhea Amantadine and anticholinergics should be tapered and stopped first (one at a time if you are taking both), as the risk of psychosis usually outweighs the modest benefit that these medications provide. Levodopa and the dopamine agonists are the other classic offenders, since high levels of dopamine in certain areas of the brain are associated with psychosis. In practice, the risk of cognitive and psychiatric complications is higher with the dopamine agonists than with levodopa. Thus, when the symptoms of psychosis demand immediate action to rescue someone who is on a combination of levodopa and dopamine agonists, the first step is usually to taper and eventually stop the agonist. Psychosis and dopamine excess can be remedied by the use of drugs, known as neuroleptics, which block the receptors activated by dopamine. These drugs have been used for over 50 years to treat severe mental illness, particularly schizophrenia. Therefore, it is extremely important that the right neuroleptic or antipsychotic drug be chosen. This is so that your healthcare provider can monitor the low but significant risk that clozapine can depress your white blood count and thereby increase the risk of serious infection. Out of 19,000+ visits tracked in the study (almost 8,000 patients), doctors started a patient on Not used antipsychotics at 1% of visits. Drowsiness, drooling, tachycardia, dizziness, constipation, low blood pressure, headache Quetiapine 25, 50, 100, 12. For more information on medical causes of disrupted sleep, including obstructive sleep apnea and congestive heart failure, please check with your physician or healthcare provider. The evaluation typically will include observations during sleep of heart rate, breathing activity, snoring, involuntary movements and quality of sleep. Voluntary movement of the legs, particularly walking, relieves the uncomfortable urge at least temporarily. Like many of the in-sleep disorders, the bed partner is more aware of the involuntary movements than the person with the symptom. Diagnostic evaluation can be fairly simple when the symptoms are obvious, but your physician or provider may prescribe an overnight sleep study to help determine a clear diagnosis. Your healthcare provider may also want to consider benzodiazepines (clonazepam), gabapentin or low-dose opiates. Discuss with your healthcare provider whether to reduce, rearrange or even eliminate daytime dopamine agonists. Examples of these behaviors may include obsession with shopping, sexual activity, eating and gambling, all of which can interfere with sleep. If you experience any of these behaviors, be sure to speak with your healthcare provider. Every attempt should be made to normalize the sleep-wake cycle and to improve sleep hygiene. Sleep hygiene can be further improved by the prudent use of physician-supervised sleeping medications such as quetiapine, clonazepam and others. Some antidepressant drugs, such as trazodone (Desyrel) or mirtazapine (Remeron), can also promote sleep due to their sedative properties. Most over-the-counter preparations are not suggested for use unless recommended by a physician, although the antihistamine diphenhydramine (Benadryl) may double as a sleeping pill and an antitremor drug because of its anticholinergic properties. If motor symptoms such as stiffness and tremor interrupt sleep because of the long gap between the last dose of antiparkinson medication in the evening and the first dose the following day, an extra dose of carbidopa/levodopa may be taken late in the evening or during the night on awakening. Stimulants such as methylphenidate (Ritalin) and mixed amphetamine salts (Adderall) can be tried. They should be given in low doses and taken in the morning initially, preferably before 8 a. Side effects include palpitations, high blood pressure, confusion, psychosis and insomnia (if the dose is too high or taken too late in the day). The non-stimulant modafinil (Provigil), approved only for treatment of narcolepsy, also is potentially useful. Its mode of action in the brain is unknown, but it has a good track record of reducing daytime sleepiness with fewer side effects because it is not a stimulant like methylphenidate and the amphetamines. In addition, the drugs commonly used to treat high blood pressure can make orthostasis worse. Any person who experiences orthostatic symptoms should inform all healthcare providers involved with their care. A good example of a frequent and straightforward parallel problem (or comorbidity) is back, neck and limb pain due almost always to degenerative arthritis of the spine. Orthostatic hypotension is usually the primary reason for the symptom, but general medical causes, especially involving the heart or lungs, must be explored. In addition, other medications prescribed by other physicians and healthcare providers, particularly medications for high blood pressure, should be thoroughly considered. Communication between all treating physicians and members of the healthcare team is mandatory in these matters. If the foregoing measures are not effective, then ask your physician or healthcare provider if medications to raise blood pressure would be appropriate in your case. Fludrocortisone (Florinef) will increase blood pressure by increasing retention of salt and blood volume. Leg edema (swelling) and high blood pressure when lying flat are potential adverse effects. Midodrine (Proamatine) increases blood pressure by stimulating the autonomic nervous system directly and is dosed three times per day. The development of high blood pressure when lying flat is greater with midodrine than fludrocortisone and should be carefully monitored. Pyridostigmine (Mestinon) can be used either as monotherapy or as an adjunctive drug to augment the blood pressure raising effect of flodrocortisone and midodrine. Ordinarily used to treat the neuromuscular disease myasthenia gravis, Mestinon has been evaluated in two single dose clinical trials (one open-label and one placebo-controlled), both of which showed a small but statistically significant elevating effect on diastolic blood pressure. Only one study, an open-label survey, has examined the long-term effect of using Mestinon for orthostatic hypotension. Therefore, the continued effectiveness of Northera should be assessed periodically by your doctor. Similar to midodrine and fludrocortisone, there is potential for the development of high blood pressure when lying flat (supine hypertension) that should be monitored carefully. Northera is only available through specialty pharmacies; your doctor has to complete a treatment form and fax it to the Northera Support Center to prescribe it. Slowed gastric emptying translates into gas and bloating, nausea, loss of appetite and pain. All of these symptoms vary in their responses to treatment with antiparkinson drugs, but usually improve with the use of drugs that specifically speed gastrointestinal movement. Dopaminergic medications can worsen nausea, but the addition of extra carbidopa (Lodosyn) to the prefixed mixture of carbidopa/levodopa in Sinemet usually helps to prevent or lessen this side effect. It should not be combined with apomorphine as it can cause lowering of blood pressure. Fortunately, good dietary management and the prudent use of stool softeners, laxatives and other bowel modulators are usually helpful. Another option for the treatment of constipation is lubiprostone (Amitiza) which increases the secretion of fluid in your intestines to help make it easier to pass stools (bowel movements). Guidance from the neurologist, primary care doctor or healthcare provider on how to use and combine these agents is essential. It results not from overproduction of saliva but from slowing of the automatic swallowing reflex that normally clears saliva from the mouth. When severe, drooling is an indicator of more serious difficulty with swallowing (also known as dysphagia), which can cause the person to choke on food and liquids, or can lead to aspiration pneumonia. Usually this is perceived as a side effect (dry mouth), but in this case it is an advantage. Other anticholinergic side effects may be seen, including drowsiness, confusion, vomiting, dizziness, blurred vision, constipation, flushing, headache and urinary retention. This patch offers anticholinergic medicine that slows production of saliva as it is absorbed into the entire bloodstream, and anticholinergic side effects similar to oral agents may be seen. Injection of botulinum toxin A (Botox) into the salivary glands of the cheek and jaw decreases production of saliva without side effects, except for thickening of oral mucus secretion. Botox is not always effective, but when it works the benefit can last for several months before it wears off and re-injection is necessary. Gum activates the jaw and the automatic swallowing muscles reflex and can help clear saliva.
