The worker was killed by a blow between the swiveling pipe and the metal railing of the working platform behind him antifungal killer buy lotrisone 10mg free shipping. General precautions and safety hints: Visually check all equipment and fittings before each operation or shift xylitol fungus sinus purchase 10 mg lotrisone. Prime antifungal en espanol purchase lotrisone 10 mg with amex, before pumping antifungal underarm cream purchase lotrisone 10 mg overnight delivery, preferably with a mixture of slurry of sand and cement ahead of the concrete. Construction Site Safety Handbook Page 155 As far as possible, use less flexible hose to reduce the pumping pressure. Replace hose before each shift, remove worn-out hoses away from service to avoid increased possibility of kinking leading to vibrations and ruptures. Suitable personal protective equipment should be provided, such as chemical resistant gloves, aprons, rubber boots, eye protectors, etc. In case the system halts or breaks down: Switch off the emergency stop and cut-off the pump. Inform the plant operator, gang leader and/or foreman in charge Check for any visual defects, particularly on the hoses or joints, Clean out the placing line Clean out the pump It is a good practice to install a shut-off or switch-off valve after the pump to enable instant stopping. No unauthorized worker should be allowed to add any liquid to the concrete, particularly water, as it will alter the mix which may lead to unexpected pumping pressure build-up. Additional precaution for high-rise pressure pumping Slope work Slopes are one of the unique characteristics of Hong Kong. Public slopes belong to the Government, and they are being maintained by the relevant works department. But a number of these slopes adjacent to heavily developed areas are privately owned. In the past, slopes in Hong Kong had experienced significant failures, resulting in loss of lives and properties. In fact, Hong Kong has a history of tragic landslides, mostly as a result of failures associated with man-made cut slopes, filled Construction Site Safety Handbook Page 156 slopes and retaining walls. The Government recorded an average of about 300 incidents each year affecting man-made slopes, walls and natural hillsides. Many are just washouts and erosion on the surfaces of slopes and hillsides, but a significant proportion relates to larger failures which can threaten lives and properties, block roads and disrupt the activities of the community. In new building developments, slope work is an integral part of the entire project. For slopes in existing building developments, maintenance work is often neglected by the owners, not to mention the safety and health conditions of the workers engaged in the slope maintenance work. In a typical routine maintenance job, workers will: clear drainage channels, weepholes, drain pipes and slope surface; repair drainage channels or pavement; maintain damaged slope surface; recondition the slope surface area, such as un-grass/re-grass, tiles repair and masonry; remove undesirable vegetation that may damage the slope surface or cause instability; Slope maintenance and stabilization often involve working at height. Safe access may be the first but not the only or most important problem a contractor or the management company staff has to solve. There had been slope maintenance workers being injured while working or disturbing the slope surface. A publication entitled "Guidelines on Safe Access for Slope Maintenance" was issued at the end of the joint exercise. In this publication, a wide range of methods, some in the form of permanent access and others by way of ad hoc measures, are identified for access provision. Some components of the safe access may reduce the visual quality of the slope and its surroundings, so the basic guidelines are to make these access provisions as inconspicuous as possible. Construction Site Safety Handbook Page 157 Access installed on a slope may lead to trespassing which is another area of concern since it involves invasion of privacy and the safety of the trespassers. Permanent access for slope work is not a requirement by law, but such provision is ideal for regular maintenance such as clearing of drainage pipes after a rainstorm and typhoon. Considering the nature of work being performed and the geographical location of the site, powered platforms such as hydraulic platforms are also commonly used for this type of work. For major slope repairs, proper scaffolds, working platforms and other safety measures should be set out in a proper method statement. Apart from working at height safety, rock drillers, shortcrete nozzle operators and hydro-seeders need to be protected from noise and dust hazards during the work process. During hydro-seeding whereby slurry of seeds, mulch, fertilizers, binders and organic additives are sprayed onto the soil surface, additional protection such as ear plugs, aprons, face shields and/or goggles should also be provided. Before work commences, conduct a risk assessment and consider the following safety measures to be provided to workers: Personal protection To protect skin from cement and cement grout, workers should wear: suitable chemical resistant gloves coveralls waterproof boots suitable respiratory protective equipment against dusts. Jack hammers or rock drilling machines should be regularly maintained to minimize noise and vibration. Skin in contact with wet cement should be washed away with large amounts of cool clean water promptly. The injury toll in the maintenance sector, very often involving fatal cases, was high and most difficult to tackle. It was not until recently that people in the industry started to manage the problems more seriously.

Cell membrane 51 A the cell membrane is composed of phospholipid, the molecules of which form two parallel surfaces (called a lipid bilayer) such that the polar phosphate groups are on the outside of the bilayer and the nonpolar lipid chains are on the inside. The membrane acts as a permeability barrier, restricting the kind and amount of molecules that enter and leave the cell. Differences between gram-positive and gram-negative species the molecular details of the cell wall and membrane structures of gram-positive and gram-negative bacteria are shown in Figure 6. Additional surface layers, such as a capsule or glycocalyx, can be found in some species of gram-positive and gram-negative bacteria. The peptidoglycan in most gram-positive species is covalently linked to teichoic acid, which is essentially a polymer of substituted glycerol units linked by phosphodiester bonds. Gram-negative organisms: Gram-negative bacteria have two the outer membrane contains O-polysaccharide, which is antigenic, and lipid A, an endotoxin. The peptidoglycan layer is located between the two membranes (analogous to a slice of bread with butter on both sides) in what is called the periplasmic space. In contrast to gram-positive cells, the peptidoglycan layer of gramnegative cells is thin, and the cells are consequently more susceptible to physical damage. The outer membrane is distinguished by the presence of various embedded lipopolysaccharides. The polysaccharide portion (O-polysaccharide) is antigenic and can, therefore, be used to identify different strains and species. Because lipid A is an integral part of the membrane, it is called an endotoxin, as opposed to exotoxins, which are secreted substances. Do not confuse endo- or exotoxins with enterotoxins, which are exotoxins that are toxic for the mucosal membrane of the intestine. The external capsule and glycocalyx Many bacteria secrete a sticky, viscous material that forms an extracellular coating around the cell. The material is usually a polysaccharide, however, in the case of pathogenic Bacillus anthracis, is poly-D-glutamic acid. If the material is tightly bound to the cell and has an organized structure, it is called a capsule (see Figure 6. Appendages Many bacteria have hairlike appendages that project from the cell wall. There are of two kinds of appendages: flagella (singular, flagellum) and pili (singular, pilus). They enable bacteria to propel themselves, for example, in response to a chemotactic stimulus. Flagella are attached to the cell wall, cell membrane, or both by a basal body, which is a complex molecular machine that rotates the flagellum like the screw propeller of a ship (Figure 6. Bacteria that have flagella often do not form compact colonies on an agar surface, but instead swarm over the surface of the agar if it is sufficiently wet, producing a scumlike mat. Pili: Pili (also called fimbriae), are shorter and thinner than flagella and function as attachment organs that promote specific cell-tocell contact (see Figure 6. The attachment can be between the bacterial cell and the host eukaryotic cell, or between one bacterial cell and another. These result in the formation of a dormant cell called an endospore inside the original cell. They are remarkably resistant to heat (they survive boiling), desiccation, ultraviolet light, and bacteriocidal chemical agents. The mature spore retains the complete machinery for protein synthesis, and new spore-specific enzymes are synthesized in the core of the spore. At the same time, many enzymes of the original vegetative (nondividing) cell are degraded. Spore germination 53 Plasma membrane Nucleoid Invagination of cell membrane to form forespore Forespore To return to the vegetative state, spores must first be subjected to a treatment that weakens the spore coat (such as heat or extremes of pH), thus allowing germination to occur. If the activated spore is in a nutritious environment, which it senses by monitoring various key metabolites, it begins to germinate. This process involves destruction of the cortex by lytic enzymes, followed by uptake of water, and release of dipicolinate from the cell. Medical significance of sporulation Some of the most notorious pathogens are spore-formers, including B. Spores of these organisms can remain viable for many years, and are generally not killed by boiling, but can be killed by autoclaving (that is, subjecting the spores to temperatures above 120oC at elevated pressure). Engulfment of forespore Formation of a double membrane around forespore In the absence of an autoclave, spores can be largely eliminated by a primary boiling to activate germination and, after a short period of vegetative growth, a second boiling. All cells, whether bacterial or human, accomplish these metabolic tasks by similar pathways. There are, however, some important differences that set bacteria apart metabolically from eukaryotic cells, and these differences can often be exploited in the development of antibacterial therapies. Characteristics of bacterial growth If bacterial cells are suspended in a liquid nutrient medium, the increase in cell number or mass can be measured in several ways. Techniques include microscopically counting the cells in a given volume using a ruled slide, counting the number of appropriately diluted cells that are able to form colonies following transfer to a solid nutrient (agar) surface, or quantitating the turbidity-which is proportional to the cell mass-of a culture in liquid medium.

Rationale for using intermittent calorie restriction as a dietary 361 treatment for drug resistant epilepsy. In particular, individuals with the disease can experience a life expectancy shortened by up to 10 years when compared with individuals without the disease, due to an increased risk of both macrovascular and microvascular complications (Bottomley and Raymond, 2007). As the worldwide prevalence of the disease increases, so too does the demand for and cost of medical care in order to treat this progressive disease (Brandle et al. These include loss of productivity for employers and loss of income for both employer and employee due to chronic sickness and absence from work, early retirement, or premature mortality (Bottomley and Raymond 2007). Type 2 diabetes mellitus has long been regarded as a chronic progressive condition that is heterogeneous in nature (Lim et al. John Yudkin, a professor of nutrition in the United Kingdom, brought attention to carbohydrate restriction as a method of losing weight, and suspected that sugar was a culprit in modern illnesses (Yudkin, 1959). Over the last 15 years, several independent groups have reexamined low-carbohydrate diets and given them the new name of "carbohydrate-restricted diets," or "ketogenic diets" if the dietary carbohydrate is sufficiently low to cause an increase in blood or urine ketone bodies (typically < 20 grams of dietary carbohydrate/day). These recent studies for the treatment of obesity have been summarized in several meta-analyses (Nordmann et al. These studies are notable in that, despite the higher fat content of the low-carbohydrate diet, the adverse changes in serum cholesterol that were predicted from other diet studies did not occur. There are very few dietary disease endpoint outcome studies, but a low-carbohydrate diet was an intervention arm in a study assessing carotid intimal thickness after 2 years (Shai et al, 2010). In this study, all diet interventions, including the lowcarbohydrate diet led to significant regression of measurable carotid intimal thickness. The effect appeared to be mediated by weight loss­induced decline in blood pressure. Vegetables with carbohydrate content from 3% to 5% were tomatoes, brussels sprouts, watercress, sea kale, okra, cauliflower, eggplant, cabbage, canned string beans, broccoli, and canned artichokes. So, before the modern medical therapies of medication and insulin, the latter being discovered in 1921, the leaders in diabetes used a lowcarbohydrate, high-fat diet for the treatment of diabetes. In the pre-insulin era, the pharmacological treatment of diabetes mellitus included a combination of modalities including alcohol, opioids, arsenic, and potassium bromide. From a textbook written in 1877: "There are few diseases which present to the practitioner so clear an indication of what is to be done. The leading authorities in the early 1900s, Frederick Madison Allen and Elliott P. Joslin, published several studies supporting the use of a lowcarbohydrate, high-fat diet for diabetes. Allen used a pancreatectomized dog model of diabetes and observed that feeding a high-carbohydrate diet led to glycosuria. If, however, the dogs were fed a high-fat, low-carbohydrate diet, the glycosuria was no longer detectable. In the treatment of diabetes in humans, Allen employed fasting, then a stepwise reintroduction of macronutrients to find the threshold at which glycosuria developed (Allen, 1914, 1915a, 1915b, 1920). Using this method, the average diet recommendation for diabetes was a diet containing 70% fat, 18% protein, 4% alcohol, and only 8% of calories from carbohydrate (Allen et al. Like Allen, Joslin recommended a 70% fat, 10% carbohydrate diet for the treatment of diabetes (Joslin, 1928).

In contrast fungus ball x ray generic lotrisone 10mg amex, central causes (such as cerebellar or brainstem infarction fungus list generic lotrisone 10mg otc, or hemorrhage) result in nystagmus that changes direction with change in the gaze direction fungus gnats mint order generic lotrisone on-line. The nystagmus of peripheral vertigo is typically fatigable (extinguishes with repeated testing) fungus gnats control cannabis purchase 10 mg lotrisone visa, while the nystagmus of central vertigo is not. In addition, the presence of nystagmus at extreme end-gaze is seen in up to 60% of normal people. Physical examination General appearance the general appearance of the dizzy patient varies widely, from the healthy young adult to the frail elderly patient. Patients who are dizzy and vomiting generally appear extremely uncomfortable, and may even be ashen and diaphoretic. Vital signs Blood pressure Hypertension in a dizzy patient should raise concern for vertebrobasilar insufficiency, cerebellar 244 Primary Complaints Ears External auditory canal: this should be inspected for vesicles (Ramsay Hunt syndrome), cerumen, and cholesteatoma. Cerebellar Cerebellar function can be evaluated using rapid alternative movements or point-to-point testing. The slow, irregular, and clumsy movements that occur with rapid alternating movements are called dysdiadochokinesis and indicate cerebellar disease. Cerebellar disease also results in movements that are clumsy, unsteady, and inappropriately varying in their speed, force, and direction. In ataxia due to loss of position sense, vision Dizziness and vertigo Cardiovascular the heart should be auscultated for the presence of dysrhythmias and murmurs. The presence of murmurs may indicate aortic stenosis or hypertrophic obstructive cardiomyopathy, both which may decrease cardiac output. In addition, the carotid arteries should be auscultated for the presence of bruits, which may indicate carotid stenosis as a contributing cause of cerebral hypoperfusion. When the eyes are closed, the patient loses balance resulting in a positive Romberg sign. With cerebellar ataxia, the patient has difficulty standing with his or her feet together regardless of whether the eyes are open or closed. Ataxia (a gait that lacks coordination with reeling and instability) may be due to cerebellar disease, loss of position sense, or intoxication. The broad-based ataxic gait of cerebellar disorders is readily distinguished from the milder gait disorders seen with vestibular or sensory loss. Rectal A rectal examination may be useful to suggest anemia from gastrointestinal bleeding, and should be considered in the dizzy patient with a history consistent with near-syncope. This serves as the most provocative way to move the otoliths and reproduce symptoms. The patient is then returned to the sitting position and the eyes are viewed again (Figure 18. In the headhanging position, the eyes beat upward (toward the forehead) and toward the affected ear in the fast phase. The nystagmus fatigues with repeated positioning, and there is usually a brief latency from the time the head-hanging position is achieved to the onset of nystagmus. This test does not need to be done rapidly, as it is a "positional" as opposed to a "positioning" test. This positive side serves as the starting point for the Epley maneuver, described in the treatment section. Dizziness and vertigo Head-thrust test this test should be performed if unilateral peripheral vestibular loss is suspected, as in vestibular neuritis or labyrinthitis. Clinical tests Orthostatic vital signs Orthostatic hypotension is generally defined as a fall in systolic blood pressure of at least 15­20 mmHg within 2 minutes of standing upright. Orthostatic vital signs may help suggest hypovolemia, but are very nonspecific, especially in the elderly, and should not be considered pathognomonic. If the patient develops reproduction of symptoms (vertigo, nausea, and nystagmus) on pneumatic otoscopy, the diagnosis may be perilymphatic fistula. Hallpike test For patients with a history consistent with vertigo, a Hallpike test (also known as the Dix­Hallpike, Nylan­Barany, or Barany test) should be performed at the bedside. This is performed as follows: the patient sits upright in the gurney with the head turned 45° to one side. The patient is then guided down to the supine position with the head overhanging the edge of the gurney. The eyes are viewed for evidence of torsional nystagmus and the patient is questioned regarding reproduction of symptoms. By turning the head 45° to one side, the posterior semicircular canal becomes aligned in the direction of 246 Primary Complaints Hyperventilation A 2 -minute hyperventilation challenge is occasionally used when psychophysiologic dizziness is thought to be the cause of dizziness. However, the utility of this test remains unclear, and symptom reproduction cannot be considered diagnostic.
