Part E: Hemoptysis • Definition—Expectoration of blood from the respiratory tract below the level of the larynx. Diagnosis • History should include symptom acuity, and quality/quantity of expectorate, presence of associated symptoms (i. In cases of massive hemorrhage, the patient may present with the affected side recumbent to prevent blood from filling the uninjured lung.

Pulmonary findings may include rhonchi, rales, decreased breath sounds, ego- phony, or a pleural rub. Extrapulmonary findings may include a diastolic murmur of mitral valve stenosis, supraclavicular adenopathy suggestive of cancer, or digital club- bing in patients with chronic lung disease. Treatment • Management of the patient’s airway, breathing and circulatory status are paramount. Supple- mental oxygen as well as crystalloid and/or blood product administration should be ad- ministered as needed. Patients with respiratory failure or difficulty maintaining a patent Pulmonary Emergencies 69 airway mandate intubation. Rotating the endo- 3 tracheal tube 90 degrees counter-clockwise so the tube concavity faces the left during intubation is sometimes successful. If available, a double-lumen endotra- cheal tube can be used although there are often complications and most physi- cians have little to no experience with the product. Arterial embolization by interventional radiology is an option for those with uncontrolled hemorrhage or when bronchoscopy is not possible or not successful. Disposition • All patients with respiratory compromise or unstable hemodynamics should be ad- mitted to an intensive care unit. There is a high incidence of recurrence in patients with self-limiting massive hemoptysis and these patients also require intensive care admission. All discharged patients should follow-up with their primary care provider or a pulmonologist. Massive Hemoptysis Expectoration of blood from lower respiratory tract (systemic bronchial vessels and low pressure pulmonary vessels) >50 ml per episode or 600 ml/24 h. The right mainstem is easily entered, the left requires specialized technique and/or equipment. Until the airway is secured with endotracheal intubation, personnel should take precautions against respiratory spread of tuberculosis. Breathing: Both before and after intubation, the patient should be positioned with bleeding lung dependent to maximize gas exchange and minimize the fill- ing of the unaffected side with blood. Fresh frozen plasma and platelets should both be considered when there is suspected coagulopathy or severe thrombocytopenia. Massive, uncontrolled hemoptysis may require a spectrum of emergent 3 specialty consultation, including cardiothoracic surgery, interventional ra- diology and pulmonary medicine. Disability: A cursory neurological examination should be sought prior to paralysis and endotracheal intubation so the need to image the head for intracranial pa- thology can be assessed. The role of radiology in the investigation and managment of patients with haemoptysis. Part F: Pleural Effusions • The pleural space normally contains a minimal amount of fluid. A pleural effusion is an excessive collection of fluid in the pleural space resulting from an underlying dis- ease process (see Table 3F. Common complaints with symp- tomatic effusions are dyspnea, pleuritic chest pain, or cough.

There may be complaints of reduced attention, concentration and generally becoming more distractible. This could be from complex tasks to patients requiring assistance with day to day tasks like cooking, dressing, meals shopping etc. Decline in memory, judgement and general slowing of thought processing can pose potential risks to the patient e. Neuropsychiatric symptoms: depression, anxiety, emotional liability, paranoia, hallucinations and delusions. These symptoms occur intermittently and can lead to agitation and aggressive behaviours. Whilst hallucinations are less common than delusions, visual hallucinations occur early in Dementia with Lewy Bodies. Behavioural symptoms: family may report intermittent periods of agitation and aggression. Frustration arising from word finding and speech difficulties can also lead to agitation. Disinhibition and inappropriate sexualised behaviours occurs in a small percentage of people with dementia. Behaviours reported include making sexualised comments even to strangers, openly masturbating and inappropriately touching people. These behaviours can sometimes reflect previous occupations, hobbies and premorbid personality. Personality changes: persons have been described by family as not being their usual selves e. Speech/language difficulties-word finding difficulties, difficulty naming objects, receptive and expressive language difficulties. Neurological examination may show ataxia, nystagmus and opthalmoplegia with excessive alcohol related cognitive impairment, such as the Wernicke-Korsakoff syndrome. Gait abnormalities and urinary incontinence could be seen in Normal Pressure Hydrocephalus. As causes of dementia could be mixed, the findings on physical examination could also be varied. Delirium David Meagher Introduction Delirium is an acute complex neuropsychiatric syndrome that is characterised by generalised disturbance of brain function occurring in the context of physical illness. It is estimated that around 10-15% of general hospital patients have delirium upon admission with a further 10-40% developing delirium during hospitalisation. Overall frequency is estimated at 11- 42% (Siddiqi ea, 2006), with the clinical rule of thumb that one in five general hospital in-patients experience delirium at some time during hospitalisation. Delirium is especially common in the elderly, those with pre-existing cognitive problems and those receiving intensive care or in hospice and nursing homes. Symptoms and differential diagnosis During the 20th century, delirium was described as a ‘clouding of consciousness’ but this rather nebulous concept has been replaced by the recognition that delirium involves a disproportionate disturbance of attentional processes, diminished grasp of the surrounding environment, and 948 impaired higher order thinking reflected in disorganised or illogical thought processes and impaired abstraction and comprehension. Delirium involves generalised disturbance of cognitive functioning and include problems with orientation, visuospatial function, short and long-term memory but attention is disproportionately affected and considered the cardinal cognitive disturbance of delirium. Inattention includes distractibility, reduced vigilance or concentration, and impaired environmental awareness. Thought process abnormalities in delirium include loosened associations, circumstantiality and tangentiality and result in disorganised thinking. This can be elicited through general observation during the interview and/or proverb interpretation. Disruptions of sleep-wake cycle are a core element of delirium and often predate the appearance of a full-blown episode. These involve sleep fragmentation or even complete sleep-wake cycle reversal and thus are more severe than the insomnia that is a common problem in hospitalised patients. Similarly, alterations in patterns of motor activity are also very common and are used to define clinical subtypes (hypoactive, hyperactive, mixed) (Meagher, 2009). Hypoactive cases are especially prone to non-detection or misdiagnosis as depression. Agitated depression or severe mania can mimic hyperactive delirium but the affective lability of delirium contrast with more sustained alterations in mood and affect in major mood disorders.

Hepatocytes extract bile acids very efficiently from sinusoidal blood; they are re-secreted into canaliculi hypertension orthostatic purchase valsartan in india. The net result of enterohepatic recirculation is that each bile salt molecule may be reused up to 20 times heart attack names valsartan 40 mg order with visa, and often 2 or 3 times during a single digestive phase (Figure 6 pulse pressure below 20 valsartan 160 mg buy with visa. Liver disease, and damage to the canalicular system, can result in escape of bile acids into the systemic circulation. Assay of systemic levels of bile acids is used clinically as a sensitive indicator of hepatic disease. Bile acids are steroids, characterised by a carbon skeleton with four fused rings, generally arranged in a 6-6-6-5 fashion. Within the intestines, bacteria convert primary bile acids to secondary bile acids, for example deoxycholate (from cholate) and lithocholate (from chenodeoxycholate). Both primary and secondary bile acids are re-absorbed by the intestines and delivered back to the liver via the portal circulation. They facilitate the digestion of dietary triacylglycerols by acting as emulsifying agents; emulsification increases the surface area of fat, making it available for digestion by lipases. They facilitate the intestinal absorption of fat-soluble vitamins (vitamin A, retinol; vitamin D, cholecalciferol; vitamin E, tocopherol; and vitamin K). Their synthesis and subsequent excretion in the faeces represents the only significant mech- anism for the elimination of excess cholesterol. In humans, roughly 500 mg of cholesterol is converted to bile acids and eliminated in bile every day. Bile acids and phospholipids solubilise cholesterol in the bile, thereby preventing the pre- cipitation of cholesterol in the gall bladder. When chyme from an ingested meal enters the small intestine, acid and partially digested fats and proteins stimulate secretion of the enteric hormones cholecystokinin and secretin. Its effect on the biliary system is similar to that on the pancreas; it simulates biliary duct cells to secrete bicarbonate and water, expanding the volume of bile and increasing the flow rate into the intestine. The processes of gall bladder filling and emptying can be visualised using an imaging technique called scintography. This procedure is utilised as a diagnostic aid in certain types of hepatobiliary disease. Scintography is the process of obtaining a photographic recording of the distribution of an internally administered radiopharmaceutical with the use of a gamma camera. As surfactants (detergents), bile acids are potentially toxic to cells and so their levels are tightly regulated. In this way a negative-feedback pathway is established in which synthesis of bile acids is inhibited when cellular levels are already high. Bile acid sequestrants bind bile acids in the gut, preventing their re-absorption. In so doing, more endogenous cholesterol is directed to the production of bile acids, thereby lowering cholesterol levels. Cholesterol synthesis occurs in the cytoplasm and microsomes (smooth endoplasmic reticulum) (Figure 6. A relatively constant level of cholesterol in the body (150–200 mg/dl) is maintained primarily by controlling the level of de novo synthesis. The level of cholesterol synthesis is regulated in part by the dietary intake of cholesterol. Cholesterol from both diet and synthesis is utilised in the formation of membranes and in the synthesis of the steroid hormones and bile acids. The cellular supply of cholesterol is maintained at a steady level by three distinct mechanisms: 1. Synthesis begins with the transport of acetyl-CoA from the mitochondrion to the cytosol. The phosphorylation reactions are required to solubilise the isoprenoid intermediates in the pathway. Intermediates in the pathway are used for the synthesis of prenylated proteins, dolichol, coenzyme Q and the side chain of haem a.

General education of medical physicists A good general education is possibly the most important aspect of a medical physicist’s training and is a factor that is often underestimated blood pressure chart for 14 year old generic 160 mg valsartan with mastercard. Most medical physicists enter the field having completed a degree in physics or a similar discipline such as engineering or occasionally computer science blood pressure chart for dogs discount valsartan 40 mg online. The ability to tackle technical or numerical problems and to apply lateral thinking to their solution requires an education that includes mathematics and a broad understanding of technical and scientific principles heart attack young adults valsartan 80 mg purchase with mastercard. The physicist should be comfortable with advanced mathematical concepts, have experience in experimental design and scientific methods, and be conversant with applied statistics, electronic troubleshooting, computer programming and instrument design. These topics are not normally covered in sufficient depth in the vocational degrees intended for health professionals such as technologists or radiographers. Postgraduate courses Most specific courses in medical physics are offered at the master’s level and are intended for individuals who already have a degree in physics. The content is usually intended to provide an overview of the applications of physics to medicine and recognizes the fact that most graduates in physics have little or no background in medicine. Courses therefore usually cover anatomy and physiology and provide an introduction to other areas of medical science. The medical physics coverage is often quite broad and includes applications in therapy and general diagnostic imaging. Bridging the gap between pure physics and medicine is achievable, whereas providing the necessary mathematical and scientific background to a non-physics graduate with a background in medical science would necessitate further undergraduate study in the relevant field. Most master’s programmes include some component of project work that aims to develop relevant research skills, while some programmes involve full-time research only. Few programmes, if any, provide a sufficient amount of practical experience relevant to the workplace. Vocational training The relatively small number of physicists in many countries makes it very difficult to establish and maintain postgraduate teaching programmes, with the 46 2. The turnover of physicists is far lower than that of technologists so that the number of vacancies cannot even justify broad courses that encompass radiotherapy. This makes it difficult for a physicist who may be working alone in an institution to gain the necessary experience by working alongside nuclear medicine technologists. Short, focused, courses in fields such as radiation safety can be quite effective, as can workshops on quality control or specific computer skills. However, the nature of the work, which is often advisory or developmental rather than involving routine activities, can be difficult to learn in a short attachment since the exact role of the physicist and the equipment can vary considerably between individual departments. Of paramount importance is the physicist’s general education as well as his or her ability to find out and synthesize information when required, and to be aware of the existence of resources. The ability to find solutions from first principles, when faced with a question, can only develop with exposure to multiple situations and problems. This normally requires a relatively long attachment working with experienced staff. Accreditation and licensing It is widely recognized that individuals using unsealed sources should be licensed and should show an understanding of the responsibility that this involves. Radiation safety officers normally undertake a specific examination to test their knowledge and practical skills. Specific vocation based accreditation is uncommon in other areas of nuclear medicine physics. In many cases, profes- sional societies require their members to have undertaken suitable basic education with relevant experience in nuclear medicine physics over a number of years. In some instances, examinations are set to test knowledge specific to the area of medical physics practised. However, it is the responsibility of the employing authorities and medical practitioners to assess the relevant training of medical physicists and to employ only suitably qualified individuals, or to ensure that suitable training is provided. Summary The medical physicist needs to be a multiskilled individual with an aptitude for general problem solving and familiarity with a wide range of the technical aspects of nuclear medicine. Although postgraduate programmes are available, they normally require 1–2 years of full-time study and do not necessarily provide practical experience relevant to the workplace. Estab- lishment of training programmes is difficult due to the small numbers involved in many countries. Maintenance contracts are strongly recommended, particularly in the case of gamma cameras, for which maintenance and calibration are highly specialized procedures. Spare parts can only be guaranteed where the supplier or manufac- turer, rather than simply a local agent, continues to be involved.

These neurotransmitters are largely made in subcortical structures prehypertension blood pressure purchase valsartan 160 mg, such as the nucleus of Meynert and locus ceruleus. Older cases have a mainly cholinergic deficit whereas younger cases have not 2784 Epitope = antigenic determinant. The balance between transmitters may be more important than the absolute level of any single substance. He also points out that there is gross loss of basal forebrain cholinergic neurones in olivopontocerebellar atrophy with no clinical dementia. Studies conducted during the 1980s found that clinico-pathological agreement on diagnosis approached 90%, an increase from 70% of some years previously. Aluminium injected into the brains of animals can produce neurofibrillary tangles, but there are ultrastructural differences between aluminium-induced and Alzheimer tangles. It is potentially possible that a genetic defect might facilitate the entry of aluminium into the brain. There is a higher level of aluminium in the water on Guam (see below) but these people get amyotrophic lateral sclerosis, and the water there is also low in calcium and magnesium. Dialysis dementia (high brain aluminium levels, no plaques or tangles) occurs unless the aluminium level has been reduced by purification procedures. Aluminium is used as a coagulant to remove particulate matter containing toxic pollutants in water. Those antioxidants may act synergistically as free radical scavengers and it is suggested that vitamin E may protect muscarinic receptors. Levels of the free radical defensive enzyme superoxide dismutase are reduced by 25-30% in the frontal cortex and hippocampus. Superoxide dismutase converts the superoxide free radical to H2O2 that is then converted to H2O by other enzymes. In the presence of certain metal ions like iron the H2O2 can be converted to the extremely toxic hydroxyl free radical. The excess of superoxide dismutase in Down’s syndrome may cause excess production of the hydroxy radical. One piece of good advice is to eat a healthy diet, including fruit and vegetables. Alzheimer patients with depression are more cognitively impaired and more disabled than are their non- depressed fellows. Eventually the postman may bring the patient home in a distressed state after the latter becomes lost on a familiar route. Clinical features of Alzheimer’s disease divided into four arbitrary stages Stage I: Memory and concentration are poor. Dysarthria, reduced vocabulary, poor grammatical construction, logoclonia (reiterating parts of words), echolalia, misspelling and duplication of parts of words, reduced reading ability, reduced ability to comprehend the speech of others, urinary incontinence, epilepsy (5-10%), dyspraxia and agnosia may be noted. Misidentification occurs (mirror sign, or talking to photographs), as do depression, delusions and hallucinations, especially visual. There are behaviour problems, emotional lability, catastrophic reactions, motor restlessness, phases of inertia, muscular rigidity, and gait apraxia. It is essential that the family and the patient know enough to initiate proceedings to cover financial, health-care and other matters before competence is lost. Treatments have been aimed at replacing neurotransmitters, stimulating intact receptors, and alleviating 2790 disturbed behaviour symptomatically. If the patient deteriorates cognitively the anticholinesterase may be slowly withdrawn to see what benefit was being derived from its prescription; if the latter is worthwhile the medication may be continued. Interestingly, 2794 these drugs may maintain their effects for some weeks after discontinuation. The ethical/moral question 2795 has been raised as to whether they inappropriately prolong life. Apathy may respond to 2790 The list of proposed drug treatments includes vasodilators (e. The selective muscarinic agonist xanomeline may reduce shouting and psychotic phenomena.
