The con sequent gas embolism is the most common cause of damage resulting from work under conditions of hyperbaric pressure hair loss cure histogen order 5 mg finast otc. Incor rect decompression can set gases free inside cells and cause transient or permanent tissue damage hair loss in men engagement cheap 5 mg finast mastercard. Acute disorders caused by decreasing pressure (coming up from a dive hair loss 20s discount finast uk, pressure chambers) the transition from hyperbaric to normal pressure can cause more or less severe de compression illness hair loss treatment yoga buy finast 5 mg. Sometimes the persons complain of itching skin: marbling of the skin may develop hair loss in men xx discount 5 mg finast mastercard, especially on the chest hair loss in men red discount finast master card, abdomen and thighs. Central nervous symp to ms may include dizziness, nystagmus, ringing in the ears, deafness, disorders of vision and speech, difficulties in breathing, paralysis, seizures. More rarely cardiocircula to ry or respira to ry symp to ms may result from an infarction, lung embolism caused by a gas bubble, or pneumothorax. Symp to ms like those described above can be caused by air embolism leading to fissures in lung tissue during to o rapid decompression. Therapy of decompression illness An indispensable therapeutic measure is immediate and sufficient recompression. They can develop, however, and then mainly as al terations in the bones or joints, especially in the hip and shoulder regions. If during the course of his work in the company the oc cupational physician finds indications that the risk assessment should be brought up to date to improve health and safety standards, he is to inform the employer. When this is necessary, the interests of the employee are to be protected (medical confi dentiality). Cadmium is stable in air; in warm air it forms a skin of the oxide, on heating it burns to form cadmium oxide (CdO). After long-term exposures, about 50 % to 75 % of the absorbed cadmium is found in the liver and kidney.

An aliquot of at least 20 ml is centrifuged at 2000 rpm and the supernatant decanted to leave a 0. The sediment which is deposited on the microscope slide in this centrifuge is fixed with a fixation spray. It is then sent to a pathologist or urologist with experience in assessment of cells; there it must be fixed and stained again. A cut-off value of 10 U/ml has proved use ful in interpreting the results; that is, values above 10 require further clarification. False positive results can be obtained when the exclusion criteria (urinary tract in fections, urolithiasis, proteinuria. Persons with recurrent microhaematuria until the source of the bleeding has been finally clarified urologically and persons with acute or chronic cystitis until re covery. After an acute in to xication until the clinical findings and labora to ry values have re turned to normal. The reader is referred to the relevant occupational medical and chemical liter ature. Nonetheless, the determination of the concentrations in biological material, which is recommended in Section 1. When the substances are taken up by inhalation, the physical state of the substance (dust particle size, vapour pressure, concentration) is of signifi cance. Methaemo globin binds oxygen very firmly and causes oxygen deficiency in the organism. In persons exposed to large amounts of aro matic nitro or amino compounds or exposed for long periods, the haem group of the haemoglobin can be damaged by oxidative cleavage of the porphyrin ring; the re sult is verdoglobin formation. At the same time, denaturation causes globin damage which can be demonstrated by staining for the so-called Heinz bodies. These changes are not reversible and lead to final breakdown of the haemoglobin and the erythrocytes. If the in to xication is very severe, aromatic nitro or amino compounds can cause de pression of the central nervous system with inebriation-like symp to ms (anilinism), ex citation, narcosis or even to xic coma. Direct skin contact can cause irritation because of damage to the barrier function of the skin. Allergic bronchial asthma can be induced in persons with the appropriate disposition. Some aromatic amino compounds can cause acute haemorrhagic cystitis from which the persons generally recover without sequelae. In man the tumours develop in the lower urinary tract, especially in the bladder, as broad-based sessile or stalked papillomas. Because of its high electron affinity, fluorine reacts with almost all other elements; it forms the electronegative monovalent component of the resulting compound. Inhalation of large amounts in high concentrations can result in im mediate death. Local exposure especially to low concentrations causes local reddening of the skin and burning pain. It is, however, not unusual for the pain not to begin until hours af ter the exposure and initially for no skin changes to be evident. Inhalation of large doses can cause pulmonary oedema, in rare cases also immediate death. On contact with the skin, hydrofluoric acid penetrates the epidermis rapidly, dam ages the subepidermal tissue and causes necrosis. Dental fluorosis is only possible if fluorides are taken up while the ameloblasts are still active. Once these cells have s to pped functioning (after age 14 years), fluoride intake is no longer associated with a serious risk for the teeth. Consultation with a medical specialist before beginning the work abroad is intended to provide the employee with information about any exceptional climatic conditions and health risks and about the medical care available in the for eign country. Schedule consultation (independent of a medical examination) general medical examination G 35 special medical examination medical assessment and advice in unclear cases supplementary examination 336 Guidelines for Occupational Medical Examinations 1 Medical consultation and examination before beginning work abroad 1. Before the person goes abroad to work again, an initial exami nation is not necessary provided that the follow-up examination on return from the previous trip was carried out during the previous 1 year. Whether or not adequate medical care is available in the foreign workplace should be taken in to account. Also for individuals working in areas outside this zone, depending on the working conditions and the results of a health risk assessment, a medical consultation should take place and perhaps even medical examinations as given in this guideline. Heat, hu midity and sunshine produce a climate to which the individual must become accli matized. Persons who are not completely healthy can also travel to warm countries and work there provided that they have been given ap propriate medical advice and have access to medical care in the foreign country. Acute illnesses and certain chronic complaints involve health risks during short visits or longer periods in foreign countries. Water from the public water supply can gen erally not be considered to be hygienically fit to drink. Only very few tropical diseases occur only in the tropics (African and South American trypano somiasis, filariasis, yaws and yellow fever). Other infectious diseases (malaria, tuberculosis, schis to somiasis, whip worm, hookworm and ascaris infections, leprosy, amoebiasis and other intestinal in fections, virus hepatitis and generalized mycoses) are very widely distributed. The disease is spread ing in to regions which were still free of malaria not long ago. The con struction of irrigation and drainage systems has led to the dissemination of schis to somiasis. Therefore special measures, especially with respect to personal hygiene and behaviour, are required.

In water vinyl chloride is poorly soluble but if it is stirred with suspending agents, stabilizers or emulsifiers, a fine suspension in water can be formed. In the ab sence of air and light, pure dry vinyl chloride liquid and gas are stable and not cor G 36 rosive. Vinyl chloride and its metabolites have their main effects in the liver (carcinogenic ef fects), blood, skin, vascular and skeletal systems.

For persons with severe visual defects or blindness the assessment is carried out in co operation with a rehabilitation centre for blind and partially sighted persons or a simi lar institution. The threshold limit value for the workplace is considered to have been exceeded if skin contact with nickel carbonyl occurs. If the exposures are to respirable and inhalable dust in general or to substances with germ cell mutagenic, carcinogenic, fibrogenic or other to xic effects, the relevant Guidelines for Occupational Medical Examinations should be consulted. Schedule general medical examination special medical examination medical assessment and advice in unclear cases supplementary examination 374 Guidelines for Occupational Medical Examinations 1 Medical examinations Occupational medical examinations are to be carried out for persons at whose work places during welding and separating of metal parts exposure to welding fumes could endanger health. S to pping inhalative to bacco consumption has been shown to result in an improvement of lung function and in a reduction of the overall risk of developing cancer, especially lung cancer. According to the results of scientific studies and workplace analyses, in the process es listed below there is a possibility of exposure to chromates and nickel (see Section 3. Typical pro fessions include: fitters, fitters on building sites, welders doing repair jobs, panel beaters, smiths, etc. However, welding fumes emitted by certain work pieces and accessory materials can have chemically irritating effects on the bronchial system, for example when the fumes contain chromates (especially during manual arc welding with high alloy coat ed electrodes containing 5 % chromium), oxides of some other alloy metals and fluorides (during manual arc welding with basic coated electrodes). A few individual cases of allergic sensitization (immediate type) of the bronchial sys tem to certain metals (cobalt, chromium, nickel) have been described. The iron oxide contained in welding fumes can be deposited in the pulmonary inter stitial tissues in the form of dust depots which can be detected radiologically. The changes detected in the radiogram, so-called siderosis, can be reversible after the end of exposure to welding fumes. In rare individual cases after high level exposures, reactive fibrotic changes in the sense of a clinically manifest pulmonary fibrosis (siderofibrosis) can develop in the areas close to the deposits of welding fume particles (see also Section 3. Aluminosis, also called aluminium dust lung, is characterized by diffuse interstitial pulmonary fibrosis which is manifested most markedly in the upper and middle fields of the lung. The risk of developing aluminosis depends primarily on the level, nature and dura tion of exposure. In addition, currently available information suggests that the indi vidual disposition also plays a role. The risk seems to be particularly high for persons exposed to uncoated or lightly oiled stamped aluminium powder at stamping ma chines in the aluminium powder producing industry. Radiological diagnosis of the early stages of aluminosis was, until recently, very dif ficult. In advanced stages the effects become spread over the whole lung and the incidence of linear opacities increases, a sign of progressive fibrosis. Case-con trol studies more often show clear evidence of pulmonary carcinogenicity. More recent meta-analyses have been published by Danielsen (2000) and Ambroise et al. This is a syndrome which develops after a latency period of only a few or up to 10 hours and is manifested in respira to ry distress and general symp to ms of raised temperature, chills and exhaustion. In persons with existing unspecific bronchial hyperreactivity, chronic bronchitis or manifest obstructive airway disease, exposure to welding fumes can cause acute air way obstruction or persistent exacerbation of the bronchial symp to ms. Ozone and nitrogen oxides in higher concentrations are also potentially to xic for mu cous membranes. The syndrome is generally reversible; however, in indi vidual cases persistent impairment of lung function is possible. Independent of these results, in individ ual cases there can be a risk especially for persons working with the processes men tioned in Section 3. After long-term exposure to chemical irritants in welding fumes or to welding fumes with to xic components or after acute in to xications resulting from accidents, persistent alterations in lung function have been described in individual cases. Reduction in vital capacity as a sign of a restrictive ventilation disorder does not appear until the disease reaches the ad vanced stages. Use of electron microscopy and energy dispersive x-ray microanaly sis reveals the dust particles deposited in the fibrotic lung areas to have the same el ementary composition as the welding fumes at the workplace. Morphological examination with the light microscope reveals that the interstitial fi brosis in the lung tissue is generally to pographically close to the dust deposits. Lung function tests in patients with advanced aluminosis reveal mainly restrictive ventilation disorders and perhaps disorders of gas exchange.

If more than thirty minutes from definitive care hair loss spray purchase cheap finast line, and warming will compromise the evacuation effort hair loss cure in the future cheap finast 5mg on-line, do not initiate warming procedures hair loss viviscal buy 5mg finast with mastercard. Patients may appear cold hair loss cure 2016 generic 5mg finast fast delivery, stiff hair loss vyvanse order finast canada, blue and may appear to be dead hair loss cure vampire buy finast 5mg visa, but this diagnosis cannot be made until they have been rewarmed in a treatment facility. Patient Education General: Follow preventive measures, including proper use of cold weather clothing, staying dry, getting out of the wind, and moni to ring buddies. Medications: Avoid medications that compromise judgment and shivering, including tranquilizers, alcohol, and some anti-depressants. Revaluation: Core temperature may continue to decrease (after drop) after the patient is removed from the cold. Follow-up Actions Evacuation/Consultant Criteria: Depending on the timeliness of evacuation, patients with severe hypothermia should be transported. A short period of successful ventilation oxygenates the patient perceived to be dead, and allows them to be handled, insulated, packaged and transported, while minimizing the likelihood of ventricular fibrillation during this process. Tissue death occurs as a result of long-term vasospasm from cold, usually above freezing. They will be swollen, pink, mildly tender, and pruritic, but will recover in 24 hours. A longer exposure (12 hours or more) produces pernio, resulting in thin, partial thickness, necrotic plaques on the dorsum of the hands or feet. These will slough without scarring in a few days, but the area may remain very painful for months or years. After a number of days, liquefaction necrosis or mummification of distal parts occurs. Assessment: the his to ry of being cold and wet along with visualization of the limbs is diagnostic. Differential Diagnosis: Frostbite requires below freezing temperatures and produces a dry, mummifying gangrene (see Frostbite). Chilblains are the early stages of trenchfoot and results in just swelling and itching of the extremity, which subsides in 24 hours. Wound Care: If necrotic, au to amputation occurs, clean the wound and use loose dry dressings. Follow-up Actions Evacuation/Consultant Criteria: Patients who are unable to ambulate or perform their mission, have recurrent injury, have au to amputation of digits or develop osteomyelitis should be evacuated. Adequate intake of both water and sodium are essential to replace losses from sweating. Insufficient water intake leads to dehydration while inadequate sodium intake or excessive water intake can lead to hyponatremia. Acclimatization: It takes about 2 weeks to fully acclimate to a hotter environment. During this time the member should gradually increase his heat exposure and activity. This reduces the likelihood of becoming 6-47 6-48 a heat casualty, but does not prevent it caution is always needed. Acclimated members will sweat earlier and more profusely but with lower salt loss. Heat injuries range in severity from heat cramps to heat exhaustion to heat stroke. While the mechanism of heat cramps is not unders to od, there is convincing evidence to suggest it is the result of sodium depletion or over-hydration. Heat exhaustion and heat stroke probably represent a continuum of disease, varying in intensity and severity of tissue damage. Subjective: Symp to ms Painful, to nic contractions of skeletal muscles frequently preceded by palpable or visible fasciculation. Assessment: Differential Diagnosis tetany due to alkalosis (hyperventilation, severe gastroenteritis, cholera) or hypocalcemia; strychnine poisoning; black widow spider envenomation or abdominal colic. Patient Education General: Patients with heat cramps usually have sodium deficits or over-hydration. Activity: Allow 2 to 3 days to replenish salt and water deficits before resuming work in the heat. Prevention and Hygiene: Consume adequate quantities of salt and water as part of the normal diet. No improvement/Deterioration: If recovery is not rapid (within 1-2 hours with oral fluids, within 15-30 minutes with normal saline), return for reevaluation. Follow-up Actions Consultation Criteria: If recover is not rapid (within 1-2 hours with oral fluids, within 15-30 minutes with normal saline). Heat exhaustion may develop over several days and is a manifestation of strain on the cardiovascular system. It occurs when the demands for blood flow ( to the skin for temperature control through convection and sweating, to the muscles for work, and other vital organs) exceed the cardiac output. Risk Fac to rs: Dehydrated and sodium-deficient members are at risk after strenuous physical activity in the heat. Subjective: Symp to ms Profound fatigue, thirst, nausea/vomiting, tingling of the lips, shortness of breath, orthostatic dizziness, headache, and syncope Focused His to ry: What have you had to eat and drink in the last 48 hoursfi Assessment: Differential Diagnosis heat stroke, simple dehydration, febrile illness Plan: Treatment 1. Patient Education General: Maintain adequate fluid and water intake and work/rest cycles in heat. However, they all need at least 24 hours of rest and re-hydration under first echelon or unit level medical supervision to reverse water-electrolyte depletion. Prevention and Hygiene: Acclimatize gradually with adequate water and dietary salt. A single episode of heat exhaustion does not imply a predisposition to heat injury and no continuing follow up or profile evaluation is required. Consultation Criteria: Repeated episodes of heat exhaustion require a temporary profile against heat exposure, evacuation and referral for a thorough evaluation. The difference between heat exhaustion and heat stroke is usually impossible to determine. Soldiers who do not respond dramatically to rest and fluid/electrolyte repletion should be observed for 24 hours for delayed complications of heat stroke. If heat stroke is suspected and body temperature is elevated, start cooling immediately! Risk Fac to rs: A his to ry of previous heat stroke, poor physical conditioning, dehydration, high work loads in a hot environment, illness with fever, medications that interfere with sweating or contribute to dehydration such as caffeine, alcohol and diuretics. Subjective: Symp to ms Dizziness, exhaustion, weakness, nausea, possible involuntary urination, confusion, delirium and other mental status changes. If they have consumed several gallons of fluid in the past 2 hours consider hyponatremia water in to xication. A patient with mental status changes should be treated as a heat stroke patient until it is proven otherwise. Auscultation: Elevated blood pressure; rapid, deep respirations dropping off to shallow and irregular respirations. Palpation: Diminished or absent sweating with hot, red skin; rapid, thready pulse. Assessment: Differential Diagnosis infection (particularly meningococcemia and P. Field expedient baths, which will keep the water cool, can be constructed by digging plastic-lined, shaded pits. Patient Education General: Avoid heat exposure until clinical recovery and a thorough medical evaluation are complete. Recovery is primarily a function of the magnitude and duration of the temperature elevation. Activity: Patients should receive profiles restricting heat exposure (a permanent profile may be issued later) until clinical recovery is complete and their heat to lerance is evaluated. Prevention and Hygiene: Avoid heat exposure for several weeks until the body can regulate heat correctly again. No improvement/Deterioration: Evacuate for additional testing and treatment with continued cooling en route. Follow-up Actions Reevaluation: Hypotensive patients who do not respond to saline may benefit from carefully titrated dopamine. Evacuation/Consultation Criteria: All heat stroke patients need manda to ry evacuation and referral. Evaluation of the potential complications of heat stroke (encephalopathy, coagulopathy, hepatic injury, renal failure and rhabdomyolysis) requires labora to ry tests not available in the basic or advanced management to ols. Any individual who suddenly becomes a casualty without being wounded, or is suffering a greater degree of incapacitation than is compatible with his injury should be considered a possible chemical victim. It is unlikely that a chemical agent would produce only a single casualty under field conditions, and a chemical attack should be considered with any sudden increase in numbers of unexplained causalities. Subjective: Symp to ms Eyes, nose and throat: Eye pain, dim vision, pho to phobia, nasal congestion, hoarseness. Blood Agents High concentrations of blood agents such as cyanide exert their effect rapidly, causing unconsciousness and death in a matter of minutes. However, if the patient is still alive after the cloud has passed (more than 5 minutes after presumed exposure), he will probably recover spontaneously. Objective: Signs Using Basic Tools: Violent convulsions; increased deep respirations followed by cessation of respiration within one minute; slowing of the heart rate until death. Assessment: Diagnosis based on clinical signs and symp to ms, environment and probability Plan: Treatment Mask self and mask patient. Blister Agents Blister agents such as phosgene, mustard gas or Lewisite attack exposed skin and mucous membranes. They penetrate clothing and force troops to wear full protective equipment, degrading fighting efficiency. The mask protects against eye and lung damage but provides only limited protection against systemic effects. No drug is available for the prevention of the effects on the skin and mucous membranes. Phosgene penetrates garments and rubber easier than other chemical agents and produces a rapid onset of severe and prolonged effects. When mixed with other chemicals, the rapid skin damage caused by phosgene will make the skin more susceptible to the second agent. If an unmasked victim were exposed to phosgene before donning his mask, the pain caused by the agent will prompt him to unmask again. Subjective: Symp to ms Burns and blisters, itching, pain, conjunctivitis, coughing, shortness of breath, vomiting and diarrhea. Objective: Signs Using Basic Tools: General: Shock after large exposure to Lewisite, resulting from protein and plasma leakage from capillaries and subsequent hemoconcentration and hypotension. Skin: Reddened and extremely pruritic; progresses in 4-24 hours to blistering, which may be severe depending on agent and exposure. Apart from mucous membranes, the face, neck and skin-on-skin areas (armpits, genitalia, webs of the digits, etc. Respira to ry tract: Swelling impeding the airway, tissue sloughing, hyperactive airways, tracheobronchial stenosis, pulmonary edema. Assessment: Diagnosis based on clinical signs and symp to ms, environment and probability Plan: Treatment Mask self. Burns: Treat burns similarly to second-degree thermal burns (clean, prevent infection). Larger blisters should be unroofed and the area irrigated 4 times daily with soapy water and covered liberally with Silvadene Cream or suitable substitute. Treat mild exposure as conjuctivitis More severe injuries require daily irrigation, to pical antibiotics and a to pical mydriatic. Apply Vaseline to lid edges to prevent adherence, reduce scar formation and allow for a path for infection to drain if present. Topical steroid may be helpful in the first 48 hrs but of no benefit after that period. Intubate patients with severe pulmonary involvement early to allow for assisted ventilation and suction of necrotic and inflamma to ry debris. Bronchodila to rs may be necessary to control airway irritability and systemic steroids may also be of benefit. With severe blistering or if Lewisite is suspected, treat as a significant thermal injury. It consists of a decontamination area: triage, emergency treatment (may be co-located with triage) and skin decontamination; a treatment area: clean holding area pending treatment, advanced treatment facility; a clean patient holding area for those pending evacuation (can be located inside the treatment area); and a hot-line separating the decontamination and treatment areas. If the prevailing winds change direction, use of the primary site may no longer be possible. The protective shelter may have visual, audible and infrared signatures that can compromise concealment. The arrangement of the operational areas must be kept flexible and adaptable to both the medical and tactical situations. Sequentially decontaminate the chemical agent protective ensemble, remove the components as well as any clothing, decontaminate the underlying skin, and pass the clean patient to the shuffle pit (see below).

Mast cell stabilisers help to prevent the onset of allergic reactions by blocking the attachment of immunoglobulin/allergen complexes to mast cells hair loss 2015 order finast on line amex. They do not provide the rapidity of relief associated with to pical antihistamines but are effective when used for longer periods of time hair loss cure testimony order cheap finast line. In recurrent seasonal allergies it is appropriate to use a mast cell stabiliser for 4 weeks before the start of an allergy season hair loss due to thyroid buy online finast. If there is prolonged exposure to allergens in perennial allergic conjunctivitis hair loss in men rain purchase finast 5mg mastercard, then the continued use of a to pical antihistamine be comes inappropriate and it is better to recommend drops containing a mast cell stabiliser such as nedocromil hair loss 4 months after surgery buy cheapest finast, lodoxamide or sodium cromo glicate hair loss 2017 purchase 5 mg finast overnight delivery. Warn patients that they might experience a mild transient burning or stinging sensation after admin istering these products. A more chronic form of allergic conjunctivitis is called vernal kera to conjunctivitis. However, it is often the case that pruritis (itching) is less prominent with blepharitis. Its management usually requires removal of the crusty matter from between the lashes with a cot to n wool bud. Early diagnosis is important as the cornea can become permanently scarred, with loss of sight. If a corneal ulcer is suspected, the eye is examined after instilling fluorescein drops, which will colour and highlight an otherwise invisible ulcer. The cornea is the transparent covering over the front of the eye and early ulcers are not visible. Keratitis (inflammation or infection of the cornea) often presents with a unilateral, acutely painful red eye and the patient complaining of pho to phobia. Acanthamoeba keratitis is commoner in soft contact lens wearers and is associated with poor lens hygiene, extended wear and swimming whilst wearing lenses. Other causes Iritis/uveitis Iritis is inflammation of the iris and surrounding structures. The inflam mation causes pain, which is felt more within the eye than the superfi cial gritty pain of conjunctivitis, and there is no discharge. Glaucoma Glaucoma occurs when the pressure of the fluids within the eye becomes abnormally high. It is the sudden onset type (acute closed-angle glaucoma) that causes a painful red eye. Emergency hospital referral is necessary in order to prevent permanent loss of sight. As the pressure builds up the cornea swells, becoming hazy, causing impaired vision and a halo appearance around lights. Treatment involves an operation to lower the pressure to pre vent it from developing again. Acute closed-angle glaucoma is rare, whereas 2% of people over 40 suffer from primary open-angle glau coma (chronic simple glaucoma). As the intraoccular pressure builds up, the optic nerve is damaged, which leads to loss of visual field, and blindness if not treated. Regular check-ups are advised if there is a family his to ry of glaucoma, especially in those over 40. Contact lenses There are two main types of lens: hard (gas-permeable) and soft (hydrogel). One-day disposable lenses, which are worn once and require no maintenance or s to rage, are becoming increasingly popular. Extended wear involves much greater risks and increases the chances of complications such as ulcerative keratitis, Acanthamoeba keratitis and papillary conjunctivitis. Contact lenses should not be worn if the patient has conjunctivitis or is using eye drops. Soft contact lenses can absorb the preservative benzalkonium chloride used in eye drops. Consequently, soft lenses should not be worn within 24 h of instilling eye drops containing this preservative. Eye problems in practice Paul Greet is a man in his forties who comes in to your pharmacy on his way home from work wanting treatment for a stye. He asks if you would make him an emergency supply of chloramphenicol eye ointment, which his doc to r usually prescribes for him. Potential Potential Potential Consequences What would I do if the harm to harm to benefit to for pharmacist patient were me/my patient patient patient of supplying/ spouse/my parent/my from not from from not supplying childfi Is this decision supplying supplying supplying different from the one I have reached for the patientfi However, the pharmacist will take in to account the consequences of not making a supply, including suffering and any potential harm from delayed treatment. A stye can be an external one: a localised infection of the hair follicles of the eyelid margin; or an internal stye: an infection of meibomian glands on the inner surface of the lid. A way of doing this would be to dip a cot to n wool bud in hot water and then gently press it against the stye. Often chloram phenicol ointment is prescribed more to protect the eye from any discharge rather than actually treat the stye. It would probably help Paul Greet to understand the natural course of styes, although if he has used chloramphenicol ointment in the past, he is likely not to be happy without a further supply this time. Sometimes recurrent styes can be associated with blepharitis, diabetes or raised lipids. A key issue for the pharmacist is the potential risk from not examining the inside of the ear and seeing how the ear looks. Diagno sis is thus best made by the doc to r, who can examine the ear with an auriscope or o to scope. What you need to know Wax Otitis externa Otitis media Glue ear One or both ears affectedfi Significance of questions and answers Wax Symp to ms Wax blocking the ear is one of the commonest causes of temporary deafness. The ear can be unblocked by using ear drops such as olive oil and various proprietary drops. A cot to n wool plug should be applied to retain the fluid and be kept in for at least 1 h or overnight. Cot to n wool buds should not be poked in to the ear as wax is just pushed further in and it is possible to damage the eardrum. If any wax remains despite this treatment, referral to the doc to r is advisable so that the wax can be considered for syringing. The use of drops to soften the wax prior to syringing the ears is recommended to make the procedure more effective. In the former (due to a furuncle or boil), the main symp to m is ear pain and in the latter, a combination of some or all of pain, itching, hearing loss and dis charge. It is more frequent in hot and humid environments and is ten times more common in summer than winter. It is possible that the same symp to ms can arise from a middle ear infection (otitis media) with a perforated eardrum. It is often intense and remains so until the drum perforates alleviating the pres sure and pain and leading to a discharge. This is performed under direct vision using microsuction or with a probe covered with cot to n wool. If there is spreading cellulitis associated, then sys temic antibiotics should be started and flucloxacillin would be the treatment of choice. Regular analgesics help and effective pain relief can be achieved using paracetamol. This can be combined with co deine when the pain is more severe, although the evidence of benefit is not definitive. Pseudomonas infections account for two-thirds and staphylococcal are the next most common. The remaining 10% of infections are fungal and Aspergillus is the most common form. Acetic acid solution or an antibacterial/ corticosteroid combination is effective. There has been a recent study which suggests that ear drops containing corticosteroids are more effective than acetic acid drops, and that steroid and acetic acid or steroid and antibiotic drops are equally effective. Acetic acid 2% solution (EarCalm spray) has both antibacterial and antifungal effects and works by increasing the acidity of the ear canal, making it more difficult for pathogens to grow. The spray must be primed before use by pressing the actua to r up and down until a fine mist is seen. The nozzle is then placed in to the ear and pressed once to deliver the correct dose. While having a shower, you can do this by placing a piece of cot to n wool coated in soft white paraffin. Do not use corners of to wels or cot to n buds to dry any water that does get in the ear canal. Try not to scratch or poke the ear canal with fingers, cot to n wool buds, to wels, etc. The middle ear is normally an air-containing compartment that is sealed from the outside apart from a small tube (the Eustachian tube), which connects to the back of the throat. Within the middle ear are tiny bones that transmit the sound wave vibrations of the eardrum to the inner ear. An infection typically starts with a common cold, especially in children, which leads to blockage of the Eustachian tube and fluid formation within the middle ear. Some times the infection takes off so quickly that the eardrum perforates, releasing the infected fluid. When this occurs, a discharge will also be present and be associated with considerable lessening of pain. It appears that many cases of otitis media settle spontaneously and the effect of taking antibiotics possibly only provides some benefit in symp to ms after the first 24 h when symp to ms are already resolving. A meta-analysis of the research done on the value of antibiotics shows the number needed to successfully treat one patient is seven. In other words, six of every seven children treated for otitis media do not need antibiotics or show no response to them. Other concerns with the use of antibiotics are increasing bacterial resistance and adverse effects such as diarrhoea, which occurs in about 10% of cases. A recent research paper suggests that it would be reasonable to delay starting antibiotics for 72h and only starting if symp to ms persist at that time. If the Eustachian tube is still blocked during a flight, pain can be experienced due to the change in air pressure. This occurs because the fluid that forms in the middle ear does not drain out completely. One method of dealing with this common problem is a minor operation in which the fluid is sucked out through the eardrum. The grommet has a small hole in the middle, which allows any further fluid forming to drain from the middle ear. The grommet normally falls out within a few months and the small hole in the drum closes over. Some children are advised not to get water in to the ear after the insertion of a grommet. However, this is often unnecessary and bathing and swimming can be undertaken without using plugs, al though it is sensible to avoid deep diving as water may enter the middle ear under pressure, which will impair hearing and may predis pose to infection. She and her parents have been regular cus to mers for years and you know she recently went to Kenya on holiday. She has had antibiotics to treat it on four previous occasions during the last 3 years. She knows from experience that if she can take some antibiotics within 24 h, the ear infection will not be so bad. In the past the doc to r has had trouble inserting the o to scope because the inside of her ear had been so swollen and painful. The problem causes a feeling of intense pressure inside the ear and she then has a discharge from the ear, which seems to ease the pain. Using the framework from the previous example, I can think about possible actions I could take. If on resolution of this infection there were exudate and debris present in the outer ear canal, she could benefit from cleaning of the ear using microsuction. She might also benefit from using an acetic acid spray, especially when she has been on holiday or swimming. Whether the pharmacist is confident about childhood problems or not the most important method of dealing with this is to listen well, not just to the presenting complaints but also to the specific concerns of the parent. Sometimes people will be more open with their concerns and some times it will be necessary to ask them about their concerns more than once. Just sharing a concern can literally diminish the perceived prob lem and make the rest of the consultation with the pharmacist more effective. Common childhood rashes Most childhood rashes are associated with self-limiting viral infec tions. They may appear as short-lived fine flat (macular) or slightly raised (papular) red spots, often on the trunk. These relatively minor illnesses occur in the first few years of life and settle without treatment. Any rash in early childhood, particularly during the first year, can be alarming and frightening for parents. Infectious diseases Chickenpox Measles Roseola infantum Fifth disease German measles Meningitis Rashes that do not blanch Chickenpox (also known as varicella) this is most common in children under 10.

A rapid decrease in platelet count, concomitant with a rising haema to crit compared to the baseline, is suggestive of progress to the plasma leakage/critical phase of the disease. If facilities for a full blood count are not available or if resources are limited, such as in outbreak settings, a full blood count or microhaema to crit should be done at the first visit to rd establish the baseline. This should be repeated after the 3 day of illness and in those with warning signs and risk fac to rs for severe disease. However, it is not necessary for the acute management of patients, except in cases with unusual manifestations. Additional tests should be considered in patients with co-morbidities and severe disease as indicated. Labora to ry confirmation is not necessary before notification, but it should be obtained. Management decisions Depending on the clinical manifestations and other circumstances, patients may either be sent home (Group A); be referred for in-hospital management (Group B); or require emergency treatment and urgent referral (Group C).

These patients are able to to lerate adequate volumes of oral fluids, pass urine at least once every six hours and do not have any of the warning signs (particularly when fever subsides). The key to the success of ambula to ry (outpatient) management is to give clear, definitive advice on the care that the patient needs to receive at home: i. Patients with fi 3 days of illness should be reviewed daily for disease progression (indicated by decreasing white blood cell and platelet counts and increasing haema to crit, defervescence and warning signs) until they are out of the critical period. Small amounts of oral fluids should be given frequently for those with nausea and anorexia. The choice of fluids should be based on the local culture: coconut water in some countries, in others rice water or barley water. Oral rehydration solution or soup and fruit juices may be given to prevent electrolyte imbalance. Commercial carbonated drinks that exceed the iso to nic level (5% sugar) should be avoided. They may exacerbate hyperglycaemia related to physiological stress from dengue and diabetes mellitus. Sufficient oral fluid intake should result in a urinary frequency of at least 4 to 6 times per day. A record of oral fluid and urine output could be maintained and reviewed daily in the ambula to ry setting. The recommended dose is 10 mg/kg/dose, not more than 3fi4 times in 24 hours in children and not more than 3 g/day in adults). Admission during the febrile period should be reserved for those who are unable to manage adequate oral hydration at home, infants, and those with co-existing conditions. These include patients with warning signs, those with co-existing conditions that may make dengue or its management more complicated (such as pregnancy, infancy, old age, obesity, diabetes mellitus, hypertension, heart failure, renal failure, chronic haemolytic diseases such as sickle-cell disease and au to immune diseases), and those with certain social circumstances (such as living alone, or living far from a health facility without reliable means of transport). Rapid fluid replacement in patients with warning signs is the key to prevent progression to the shock state. If the patient has dengue with warning signs or signs of dehydration, judicious volume replacement by intravenous fluid therapy from this early stage may modify the course and the severity of disease. Start with 5fi7 ml/kg/hour for 1fi2 hours, then reduce to 3fi5 ml/kg/hour for 2fi4 hours, and then reduce to 2fi3 ml/kg/hour or less according to the clinical response (see Textboxes H, J and K). If the haema to crit remains the same or rises only minimally, continue at the same rate (2fi3 ml/kg/hour) for another 2fi4 hours. If the vital signs are worsening and the haema to crit is rising rapidly, increase the rate to 5fi10 ml/kg/hour for 1fi2 hours. Reassess the clinical status, repeat the haema to crit and review fluid infusion rates accordingly. Reduce intravenous fluids gradually when the rate of plasma leakage decreases to wards the end of the critical phase. This is indicated by urine output and/or oral fluid intake improving, or the haema to crit decreasing below the baseline value in a stable patient. Parameters that should be moni to red include vital signs and peripheral perfusion (1fi4 hourly until the patient is out of the critical phase), urine output (4fi6 hourly), haema to crit (before and after fluid replacement, then 6fi12 hourly), blood glucose and other organ functions (such as renal profile, liver profile, coagulation profile, as indicated). Use the ideal body weight for calculation of fluid infusion for obese and overweight patients (Textboxes J and K). Patients may be able to take oral fluids after 26 a few hours of intravenous fluid therapy. Patients should be moni to red by health-care providers for temperature pattern, volume of fluid intake and losses, urine output (volume and frequency), warning signs, haema to crit, white blood cell and platelet counts (Textbox K). Depending on the clinical picture and the facilities of the hospital or health centre, other labora to ry tests (such as liver and renal functions tests) can also be carried out. All patients with severe dengue should be admitted to a hospital with access to blood transfusion facilities. Judicious intravenous fluid resuscitation is the essential and usually sole intervention required. The crystalloid solution should be iso to nic and the volume just sufficient to maintain an effective circulation during the period of plasma leakage. Plasma losses should be replaced immediately and rapidly with iso to nic crystalloid solution: in the case of hypotensive shock, colloid solution is preferred (Textbox L). Continue replacement of further plasma losses to maintain effective circulation for 24fi48 hours. For overweight or obese patients, the ideal body weight should be used for calculating fluid infusion rates (see Textboxes J and K). All shock patients should have their blood group taken and a cross-match carried out. Blood transfusion should be given only in cases with established severe bleeding, or suspected severe bleeding in combination with otherwise unexplained hypotension. Input is typically much greater than output, and the input/output ratio is of no help in judging fluid resuscitation needs during this period. Start intravenous fluid resuscitation with iso to nic crystalloid solutions at 5fi10 ml/kg/hour over one hour in adults and 10fi20 ml/kg/hour over one hour in infants and children. After this second bolus, if there is improvement continue with crystalloid solution and reduce the rate to 7fi10 ml/kg/hour for 1fi2 hours, then continue to reduce as above. If haema to crit decreases compared to the initial reference haema to crit (especially if the repeat haema to crit is below the baseline, for example < 35fi40% in adult females, < 40fi45% in adult males), and the patient still has unstable vital signs, this may indicate bleeding. Cross-match fresh whole blood or fresh packed red cells and transfuse if there is severe overt bleeding, If there is no bleeding, give a bolus of 10fi20 ml of colloid, repeat clinical assessment and determine the haema to crit level. A senior staff member should carry out a review to consider blood transfusion (see Section 2. After the initial dose, reduce the rate to 10 ml/kg/hour for 1 hour, then reduce to 7 ml/kg/hour. If the haema to crit decreases compared to the initial reference haema to crit (especially if the repeat haema to crit is below the baseline, for example, 28 < 35fi40%), and the patient still has unstable vital signs, this may indicate bleeding. Cross-match fresh whole blood or fresh packed red cells and transfuse if there is severe overt bleeding. If there is no bleeding, give a bolus of 10fi20 ml/kg of colloid over 1 hour, repeat clinical assessment and determine the haema to crit level. The action plan for treating patients with hypotensive shock is outlined below (also see Textbox D and Figure 7). For all patients (infants, children and adults), initiate intravenous fluid resuscitation with crystalloid or colloid solution at 20 ml/kg as a bolus given over 15fi30 minutes to bring the patient out of shock as quickly as possible. The intra-osseous route should be attempted if peripheral venous access cannot be obtained. Then continue with crystalloid infusion and gradually reduce to 5fi7 ml/kg/hour for 1fi2 hours, then to 3fi5 ml/kg/hour for 2fi4 hours, and finally to 2fi3 ml/kg/hour (or less), which can be maintained for up to 24fi48 hours (Textbox H). Consider reducing intravenous fluid earlier if oral fluid intake and urine output improve. If the condition improves, reduce the rate to 7fi10 ml/kg/hour for 1fi2 hours, then change back to crystalloid solution and reduce the rate of infusion as mentioned above. The rate and volume of each bolus infusion should be titrated to the clinical response. Patients with severe dengue should be admitted to the high-dependency or intensive care area and be managed by senior staff. Parameters to be moni to red include: alertness and comfort levels, vital signs and peripheral perfusion (every 15fi30 minutes until the patient is out of shock then 1fi2 hourly). In general, the higher the fluid infusion rate, the more frequently the patient should be 32 moni to red and reviewed in order to avoid fluid overload while ensuring adequate volume replacement. If previously not detectable, pleural effusion and ascites should be detectable after fluid boluses. If resources are available for blood gas and/or lactate analysis, capillary or venous blood should be sampled for repeated analysis to moni to r changes in the circulation during fluid replacement. An arterial line has certain advantages but its placement is hazardous because of the attendant bleeding from failed attempts. Urine output should be checked regularly (each hour until the patient is out of shock, then every 1fi2 hours). The first urine volume after bladder catheterization should be discarded because the duration in the bladder is unknown. Haema to crit should be moni to red (before and after fluid boluses until stable, then 4fi6 hourly). In addition, there should be moni to ring of: blood glucose (before fluid resuscitation and repeat as indicated); arterial or venous or capillary blood gases; lactate; to tal carbon dioxide/bicarbonate (every 30 minutes to 1 hour until stable, then as indicated); and other organ functions (such as renal profile, liver profile, coagulation profile) before resuscitation and as indicated. It is important to note that during fluid therapy, blood samples for haema to crit should be timed such that they are taken before or after the infusion of a known volume of intravenous fluid. The interpretation will be most meaningful if the corresponding haemodynamic state, or response to fluid therapy and the acid-base balance, are known at the time of blood sampling. Random haema to crit levels, such as random blood glucose in diabetes mellitus, may not be meaningful for interpretation of the real-time clinical situation. A rising or persistently high haema to crit to gether with unstable vital signs (such as narrowed pulse pressure) indicates active plasma leakage and the need for a further bolus of fluid replacement. However, a rising or persistently high haema to crit to gether with stable haemodynamic status and adequate urine output does not require extra intravenous fluid. In the latter case, continue to moni to r closely and it is likely that the haema to crit will start to fall within the next 24 hours as plasma leakage s to ps. On the other hand, a decrease in haema to crit to gether with stable haemodynamic status and adequate urine output, indicates haemodilution and/or reabsorption of extravasated fluids In this case intravenous fluids must be discontinued immediately to avoid pulmonary oedema.
