The sweat when it evaporates from the skin surface uses the heat of the skin to antibiotic treatment for pink eye generic colchicine 0.5mg without a prescription change its state antibiotic resistance on the rise order on line colchicine. Sweat production increases with temperature rise in the environment virus 912 buy colchicine cheap, nervous tension or physical activity topical antibiotics for acne pregnancy order colchicine australia. Apocrine Glands or Odoriferous these glands are found only in certain body areas i antibiotics good or bad discount colchicine online master card. It is these glands that can give rise to are antibiotics for acne good 0.5mg colchicine fast delivery unpleasant body odours as our resident bacteria attack the fat in the secretion. Gland development takes place at puberty and the secretion is under nervous as well as hormonal control. They differ from eccrine glands in that they are normally associated with hair follicles and open above the level of the sebaceous gland. Sebaceous Glands Found in all areas of the skin except soles of feet, palms of hand or between the fingers and toes. They are most numerous in the scalp, forehead, nose and beard areas as well as on the back between the shoulder blades. The outer epidermis of the skin is concerned mainly with protection: Protection against invasion by micro-organisms. The dead stratum corneum acts as a physical barrier when intact, due to the dead cells not providing any food or moisture for micro-organisms to live on. This protein along with the physical properties of the dead cells forms a waterproof barrier Repair. The stratum basale or germinative layer can replace and repair damaged areas of the skin. Normal epidermal loss due to friction is also replaced by cell division in this region. Excess friction as on the soles of the feet and palms of the hands can lead to a greater increase in the thickness of the stratum lucidium and stratum corneum for protective purposes Additional Functions of the Skin. The skin can detect changes in the environment both favourable and unfavourable and by communication with the nervous system the correct action can be followed. Synthesis of vitamin D through the action of the ultra violet rays of the sun on steroids present in the upper skin layers. Inflammation and Healing Inflammation is part of the complex biological response of vascular tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. Inflammation is a protective attempt by the body to remove the injurious stimuli and to initiate the healing process. When tissue cells become injured they release a number of chemicals that initiate the inflammatory response. Inflammation is characterized by 5 distinct signs, each of which is due to a physiological response to tissue injury. The area becomes painful (dolar), swelling occurs (tumor), vasodilation causes redness (rubor) and temperature increase within the tissues (calor) as pain and swelling intensify impairment of function occurs (functio laesa). It is important to understand how the skin reacts to inflammation following the superficial wounding caused by micro-pigmentation. With this understanding you will be able to advise First Platform to Permanent Make Up your clients on aftercare during the expected downtime period following micro pigmentation treatment. Acute Skin Inflammation Following Micro-Pigmentation Acute inflammation is a short-term process, usually appearing within a few minutes of the cell trauma being induced by micro-pigmentation. Damage occurs from the initial trauma to the cells and tissues, where the local network of ruptured blood vessels bleed into the tissue spaces and the cell walls rupture. Within seconds and up to 10 minutes after the initial trauma local blood vessel constriction occurs. This vasoconstriction minimises blood loss from the area and initiates clotting (haematoma). This triggers the lysosomes (waste disposal unit within a cell) found within the dead and damaged cells to start to leak digestive enzymes through their ruptured membranes. These enzymes act as inflammatory mediators causing surrounding arterioles and capillaries to dilate (calor and rubor) and cause stimulation of surrounding pain receptors (dolar). Pain receptors are specialised nerve endings located throughout the body in most body tissues. Once the nerve endings are stimulated by these chemicals they begin firing the nerves that are connected to them and send pain signals to the spinal cord and brain. As blood vessels dilate, they become more permeable and within a few hours exudation increases. As the vessel walls enlarge the speed of flow decreases due to vessels being packed with cells. The stasis of blood allows leukocytes to move along the endothelium and escape through the capillary wall, along with plasma and other circulating defensive substances such as antibodies, phagocytes, and fibrinogen to the site of the injury. The First Platform to Permanent Make Up arrival of these specialised cells (antibodies, phagocytes) lead to the engulfing of dead cells, foreign material or infectious agents. As fluid moves out of the capillaries, stagnation of flow and clotting of blood in the small capillaries occurs at the site of injury. This process is caused as fibrinogen produces fibrin which forms a mesh of fibres creating a collection site for red blood cells (haematoma) and also traps micro-organisms preventing their movement further from the injury site. This increased collection of fluid into the tissue spaces causes it to swell (tumor). This expansion of chemical activity in surrounding tissues produces the zone of secondary injury. The excess fluid and cells collect in the spaces between the tissues around the site of the trauma and oedema occurs. As fluid and cells try to occupy a limited amount of space, the pressure caused on nerve endings is perceived as pain. The first is a liquid, which can be evacuated by the circulatory system and the second is comprised of proteins which have to be evacuated by the lymphatic system. First Platform to Permanent Make Up the lymph vessel diameter and the flow of the lymph system being decreased causes the swelling to occur in the first 24 hours following micro-pigmentation. Within 12 hours of injury macrophages move in to digest tissue debris to clear the way for peripheral cells to begin the process of mitosis. Tissue repair overlaps the inflammatory process and within 48 to 72 hours the haematoma is sufficiently diminished to allow for this new growth of tissue. As the damaged skin within the epidermal layers begins to regenerate, the deeper soft tissues will replace damaged cells with scar tissue. The fibroblasts release collagen, elastin and reticulin fibres forming a mesh network to reconnect tissues. Over the next 3 day’s mitosis continues and all around the injured area capillary loops develop (angiogenesis). These sprouting vessels originate from pre-existing vessels and appear as minute red granules, hence the name granulation tissue. As the circulation is increased by these additional blood vessels replacing damaged ones, more oxygen and nutrients become readily available to these cells to aid in speeding up the healing process. When circulation is increased it automatically increases lymphatic flow with the movement First Platform to Permanent Make Up of tissue fluid between the 2 systems, allowing the excess build up of lymph to be drained reducing swelling. Therefore we cannot prevent inflammation, however we can speed up the processes involved by application of cold therapies following micro-pigmentation for the first 72 hours following treatment. Whenever trauma occurs to the surface of the epidermis the protective barrier will be impaired, the application of micro-pigmentation treatment will cause a burn, cut or puncture wound to the area infused with pigment. When treating more mature clients or clients with more sensitive skin, there is a higher tendency to bruise and tear the skin resulting in a greater inflammatory response. The healing process can differ from one client to another; there are several factors to consider such as. Client lifestyle As a rule the older you are (once passed 25 years) the slower the expected healing rate. Remember the superficial tissues will display signs of healed skin long before the internal layers have completed the full healing process. The following is a general guideline to expected healing rates: For Eyeliner and Brows. Full 6 week healing period required whatever age of client First Platform to Permanent Make Up Common Skin Conditions Papule xi– Small, solid raised area of unbroken skin which often develops into a pustule. Pustule xii– Consists of a small collection of pus which is visible through a raised portion of the epidermis. Vesicle – Small blister raised above the skin’s surface and containing Serum (a pale yellow liquid similar to blood plasma). Tumor – Swelling of the skin larger than a nodule, consisting of hard or soft tissue. First Platform to Permanent Make Up Weal – White raised area of the skin containing fluid surrounded by a red area. Skin Tag xvii– these are common in the neck of the elderly, but can also be found in the areas of skin folds such as underarms, beneath breasts, eyelids and groin areas. A doctor may remove them if they prove to be a nuisance or a therapist qualified in advanced electrolysis. Milia xviii– this is a small sub-epidermal cyst containing keratin and producing a small white papule. In adults the contents are easily expressed after cutting the overlaying epidermis with a cutting-edge needle. First Platform to Permanent Make Up Xanthomas xix– Yellow plaques around the skin of the eyelids, these are thought to be connected with certain medical conditions such as high cholesterol, diabetes and blood pressure disorders. Allergies – Abnormal reaction of sensitivity of the body tissue to an individual substance which does not affect the majority of people. The condition usually subsides over time with no trace following removal of the allergen, Antihistamines can relieve symptoms. Keloid Scar xxi– Overgrowth of abnormal scar tissue, characterised by an excessive build up of collagen fibres. Skins with a tendency towards keloid formation should avoid procedures where the skin is pierced or damaged leading to the laying down the scar tissue. Some medical treatments are available to reduce scaring however results vary and are limited. First Platform to Permanent Make Up Pigmentation Disorders Macule xxii– Small abnormally coloured area of skin which is level with the skin’s surface so may be seen but not felt. Freckles (Ephelides) xxiii– Small brown macules, common on blonde or red haired people. Lentigenes (Liver Spot)xxiv Hyper-pigmented areas of skin larger than freckles in childhood lentigo simplex can occur. Chloasma xxv– Patchy pigmentation usually found on the cheek area, nose and forehead, lower arms, back of hands and chest. The condition is common in pregnancy usually disappearing shortly after the birth, but can also be triggered by the use of oral contraceptives. There is thought to be a connection with raised levels of oestrogen triggering the melanin production. First Platform to Permanent Make Up Dermatosis Pupulosa Nigra xxvi– Commonly known as flesh moles, these raised pigmented papules are benign growths that are commonly seen on black skins. Leuoderma (Vitiligo) xxvii Patches of un pigmented skin that can occur anywhere on the face or body due to an autoimmune trigger which causes the breakdown of melanocytes in certain areas of the skin. If vitiligo occurs in areas that are hairy, the pigment in the hair is also affected causing the hair to grow through white. Albinism xxviii the skin is unable to produce melanin and the hair and eyes lack colour. Hair is usually white blonde in appearance and eyes will be pink and extremely sensitive to light. Pre-Malignant Skin Conditions Cutaneous Horn – Warty looking growth protruding from the skin. First Platform to Permanent Make Up Keratonacanthoma xxix Rapidly growing skin tumour on sun exposed areas. Actinic Cheilitis xxxi– Grey, scaly areas on lower lip or corners of mouth which are the result of sun exposure or smoking. First Platform to Permanent Make Up Dysplastic Naevi xxxii– Inherited trait, multiple large naevi that carry risk of becoming malignant. Malignant Skin Conditions Basal Layer Carcinoma xxxiv Also known as a rodent ulcer, these are usually seen in the elderly and starts as a spot that fails to heal. They can occur from an existing mole, and these should be checked for irregular pigmentation or changes in colour and size. Conditions and Disorders Sebaceous Gland Disorders Acne Vulgaris xxxvii this disorder is due to overactivity of the sebaceous glands causing the follicles to become blocked with a plug of sebum and keratin. Since many sebaceous glands are located on the face, chest and back, these are the most common sites for the disorder. The disorder usually starts at puberty, when increased Androgen production from the sex organs and adrenal glands causes increased sebum production. Black heads First Platform to Permanent Make Up (comedones) are formed by the oxidation of sebum and bacteria may become active in the follicle, producing pus and resulting in inflammation. Acne usually affects more men than women, and may be affected by such things as diet, stress, weather, premenstrual tension etc. Acne is usually at its worst between 14-18 years, and diminishes and eventually disappears in the early twenties. Oxytetracycline; ultra-violet radiation in doses which induce erythema and peeling; dietary restriction if the client feels certain that foods are involved (no scientific evidence for this) ; oral contraceptive therapy i. Acne Rosacea xxxviii Sometimes just called Rosacea, it is often associated with excess sebum production. Unlike Acne Vulgaris, there is no blockage of the ducts leading to comedones, but inflammation occurs around the sebaceous glands producing papules and pustules.

If the patient is fair-skinned jaundice w ill give it a yellow tinge w hich w ill not be obvious in those of tanned or darker colour antibiotic impregnated cement generic 0.5 mg colchicine. It is best to infection of the cervix order colchicine with a visa look for jaundice in the corners of the eye in natural daylight antibiotic list of names order colchicine no prescription, as som e form s of artificial lighting can im part a yellow tinge bacteria que causa la gastritis buy generic colchicine 0.5mg on-line. A patient w ith jaundice w ill often com plain of an itching skin bacteria zip line girl discount colchicine 0.5 mg, and state that he has had nausea and vom iting for 2 to antibiotics for acne bacteria cheap colchicine express 4 days before the colouring w as noticed. His urine w ill be the colour of strong tea and his faeces w ill be putty-coloured. On a ship the m ost likely causes of jaundice are ineffective hepatitis and gallstones or alcoholic liver cirrhosis. Unless the Radio M edical Doctor advises otherw ise it should be assum ed that the patient has infective hepatitis and this m eans that he should be in strict isolation. It m ay occur as a com plication of appendicitis after about 24– 48 hours or certain other serious diseases of the contents of the abdom en. The onset of peritonitis m ay be assum ed w hen there is a general w orsening of the condition of a patient already seriously ill w ith som e abdom inal disease. It com m ences w ith severe pain all over the abdom en – pain w hich is m ade w orse by the slightest m ovem ent. The abdom en becom es hard and extrem ely tender, and the patient draw s up his knees to relax the abdom inal m uscle. Vom iting occurs and becom es progressively m ore frequent, large quantities of brow n fluid being brought up w ithout any effort. The pallid anxious face, the sunken eyes and extrem e general w eakness all confirm the gravely ill state of the patient. Give benzyl penicillin 600 m g intram uscularly and m etronidazole 400 m g at once and repeat both every 8 hours for 5 days. For patients allergic to penicillin give erythrom ycin 500 m g and m etronidazole 400 m g at once, and repeat both every 8 hours for 5 days. M ake notes of the patient’s tem perature, pulse and respiration every 1/2hour, and any change, for better or w orse, in his condition. Ulcers Peptic ulceration – duodenal and stom ach ulcers this is a special type of ulcer w hich develops in the w all of the stom ach or duodenum. A shallow ulcer m ay heal w ithin a short tim e but m ore often it becom es deep seated and causes recurring bouts of indigestion w ith pain. At first, discom fort is noticed about three hours after m eals at a point half w ay betw een the navel and the breastbone in the m id-line or slightly tow ards the right side. W ithin days or w eeks the discom fort develops into a gnaw ing pain associated w ith a feeling of hunger occurring 1– 3 hours after m eals. Vom iting is uncom m on but acid stom ach fluid is som etim es regurgitated into the m outh – the so-called heartburn. Bouts of indigestion lasting w eeks or m onths alternate w ith sym ptom -free periods of varied length. Gastric ulcer pain tends to com e on sooner after a m eal and vom iting is m ore com m on than w ith duodenal ulceration. On exam ination of the abdom en, tenderness localised to the area m entioned above w ill be found by gentle hand pressure. Treatm ent the patient should rest in bed but m ay be allow ed up for w ashing and m eals. Frequent sm all m eals of bland food should be provided w ith m ilk drinks in betw een. Antacids such as M agnesium trisilicate should be given half w ay betw een m eals also Cim etidine 400 m g 12 hourly. Pain relief tablets are not necessary and aspirin, w hich often irritates the gut, should never be given. M ost peptic ulcers, gastric or duodenal, have a tendency to bleed, especially if they are long standing. The bleeding m ay vary from a slight oozing to a profuse blood loss w hich m ay endanger life. Sm all am ounts m ay not be detected but larger am ounts of digested blood turns the faeces, w hich m ay be solid or fluid, black and tarry. In som e cases fresh, bright red blood m ay be vom ited; but, if it is partially digested, the vom it looks like coffee grounds. The patient usually has had a history of indigestion and som etim es the sym ptom s m ay have increased shortly before haem orrhage takes place. General treatm ent the patient m ust be put to bed at once and should be kept at rest to assist clot form ation, see internal bleeding. A pulse chart should be started to w atch for a rising pulse rate w hich w ould be an indication for urgent hospital treatm ent. The patient should be given nothing by m outh during the first 24 hours except sips of iced or cold w ater. After the first 24 hours sm all am ounts of m ilk or m ilky fluids can be given w ith 15 to 30 m l of m ilk each hour for the first 12 hours. Specific treatm ent Give m orphine 15 m g intram uscularly at once, then give 10 to 15 m g every 4 to 6 hours, depending on the response to treatm ent w hich aim s at keeping the patient quiet, at rest and free from w orry. If bleeding continues at a w orrying rate, w hich w ill be indicated by a rising pulse rate and a deterioration in the patient’s condition, all that can be done is to increase, if possible, the efforts to get the patient to hospital and attem pt to m eet fluid requirem ents by giving rectal fluids. When perforation occurs there is a sudden onset of agonising abdom inal pain felt at once in the upper central part before spreading rapidly all over and being accom panied by som e degree of general collapse and som etim es vom iting. The patient is very pale and apprehensive and breaks out in a profuse cold sw eat. The tem perature usually falls but the pulse rate is at first norm al or slow, although w eak. The patient lies com pletely still either on his back or side, w ith his knees draw n up, and he is afraid to m ake any m ovem ent w hich m ight increase his agony – even talking or breathing m ovem ent are feared and questioning is often resented. Large perforations produce such dram atic sym ptom s that the condition is unlikely to be m istaken for other causes of abdom inal pain w here the patient is likely to m ove about in bed and cry out or com plain w hen pain increases. The pain is m ost severe just after perforation has occurred w hen the digestive juices have escaped from the gut into the abdom inal cavity. How ever, after several hours the pain m ay becom e less severe and the state of collapse be less m arked but this apparent recovery is often short-lived. On feeling the abdom en w ith a flat hand the abdom inal m uscles w ill be found to be com pletely rigid – like feeling a board. Even light hand pressure w ill increase the pain and be resented by the patient, especially w hen the upper abdom en is felt. The patientcannotrelax the abdom inal m uscles w hich have been involuntarily contracted by pain. But: s w ith a perforated ulcer, the pain is usually in the upper m iddle abdom en at first and not around the navel as in appendicitis; s w ith a perforated ulcer, the central upper pain rem ains as the m ain source w hen the pain starts to be experienced elsew here, w hereas in appendicitis the pain m oves – the central colicky pain becom ing a sharp pain in the right low er quarter of the abdom en;and s a patient w ith a perforation usually has a history of previous indigestion but this does not apply to patients w ith appendicitis. General treatm ent It is essential that the patient should be transferred to hospital as quickly as possible. A tem perature, pulse, respiration chart should be started with hourly readings for the first 24 hours and then four hourly. The perforation m ay close naturally if nothing is given by m outh for the first 24 hours. Fluid requirem ent during this period can be m et by giving fluid per rectum if the patient is thirsty and pain relief has been adequate. Specific treatm ent It is essential to achieve adequate pain relief so give m orphine 15 m g intram uscularly with an anti em etic at once. In a case of severe pain not satisfactorily controlled by that injection, a further injection m ay be given within the first hour. Thereafter, the injection should not be repeated m ore frequently than every four hours. All patients, unless sensitive to penicillin, should be given benzyl penicillin 600 m g intram uscularly at once, followed by 300 m g every six hours until the patient is seen by a doctor. If the patient is sensitive to penicillin, seek advice urgently regarding use of alternative antibiotics. Subsequent m anagem ent After the first 24 hours, if progress is satisfactory, a sm all am ount of m ilk or half m ilk/half w ater can be given. Apart from m ilk and w ater, the patient should consum e nothing until he is in hospital ashore. There is m arked irritation around the anus caused by the m igration of the fem ale w orm s w hich pass through the anus to lay eggs on the surrounding skin. This irritation occurs particularly at night w hen w arm in bed and the im pulse to scratch becom es alm ost irresistible. W orm eggs then contam inate the anal skin and are deposited on clothing and bedclothes. Failure to w ash the hands each tim e after contact can then result in personal reinfection or the contam ination of foodstuff or conveying the eggs to another person. The nails should be kept short and the hands should be w ashed scrupulously after defecation or scratching. If there should be evidence of reinfection, the treatm ent m ay be repeated after a fortnight. Infection usually results from eating contam inated salads or vegetables w hich have been insufficiently cooked. The first sign of infestation m ay be the presence of a w orm in the faeces but vague abdom inal pain and either diarrhoea or constipation m ay occur. Specific treatm ent the patient should be treated w ith M ebendazole in the sam e dosage as that advised for threadw orm s. Tapew orm s Infestation is conveyed by eating infected pork or beef w hich has been cooked insufficiently to kill the w orm eggs. The w orm usually grow s to a length of m any feet m ade up of w hite flat segm ents. There m ay be no sym ptom s but, in som e cases, there is an increased appetite w ith vague abdom inal pains and occasional diarrhoea. Treatm ent on board is not advised and should only be carried out under m edical supervision. The head of the penis becom es constricted by the tight band of foreskin, and then swollen, congested, and painful. This is done by pressing the head of the penis backw ards w ith the thum bs and, at the sam e tim e, draw ing the foreskin over and forw ard w ith the fingers (Figure 7. Testicular pain In all cases of disease or injury to the testicles, the m an should be referred to a doctor for exam ination at the next port, even if the condition appears to be better. Tw isted or inflam ed testicle (Torsion) s Tw isting of the testicle can follow a sudden effort causing the testicle to tw ist on its cord and cut off the blood supply. This is an uncom m on condition and, w hen it occurs, frequently affects a testicle that is suspended in an abnorm al (horizontal) line. Alw ays rem em ber this can be a com plication of gonorrhoea, see urethritis or m um ps. The scrotum also becom es inflam ed and fluid w ill collect inside it adding to the sw elling and pain. It m ay be difficult to tell the difference betw een the tw o conditions but the follow ing facts w ill be of help. If w ithin the hour the pain is partially relieved, you are probably dealing w ith an inflam m ation; if not, or the pain is w orse, the condition is a tw isting of the testicle. Put the patient to bed and support the testicles by placing a pillow betw een the legs and letting the scrotum rest on this. If an infection is suspected give Doxycycline 100 m g every 12 hours for 10 days in addition to the painkillers. Injury to the testicles this not uncom m on condition is usually the result of falling astride a rope under tension or a hard surface. Depending on the severity of the injury bruising w ill appear on the scrotum and can extend up the shank of the penis, up the abdom inal w all and dow n into the thighs. General treatm ent the patient should be put to bed w ith the testicles supported on a pillow. Depending on the severity of the pain he should be given either tw o paracetam ol tablets or one codeine 30 m g tablet every 6 hours. Other sw ellings of the scrotum Tw o conditions should be borne in m ind: s A large hernia w hich has passed dow n from the groin into the scrotum ; s A hydrocoele. Both these sw ellings can becom e very large, but there is no great tenderness, no inflam m ation, no rise in tem perature or pulse rate, and the patient does not feel ill. A hydrocoele is a collection of fluid in the scrotum, often caused by a m inor injury w hich the patient m ay not rem em ber. In contrast to those caused by tw isting or infection, these sw ellings are not inflam ed or tender, and the Figure 7. There are tw o w ays to distinguish a hydrocoele from a hernia in the scrotum : s In a darkened room, place a lighted torch behind the sw elling. If it is entirely in the scrotum suspect a hydrocoele; if it is continuous w ith a sw elling in the groin, then it is a hernia (Figure 7. Treatm ent the treatm ent for both these conditions is surgical and the m an should be seen at the next port by a doctor. In the m eantim e som e relief m ay be obtained by supporting the scrotum in a crutch bandage, particularly if the m an has a hydrocoele. Renal colic A stone m ay rem ain in the kidney w ithout causing any trouble but often it causes a dull pain in the loin accom panied on occasion by passing blood in the urine. Acute pain (renal colic) does not arise until a stone enters the tube (the ureter) leading from the kidney to the bladder. It starts in the loin below the ribs then shoots dow n to the groin and testicles.

Objectives 2 Through efficient antibiotic resistance activity colchicine 0.5mg on line, focused antibiotic groups discount 0.5mg colchicine otc, data gathering: ­ In patients with hypothermia secondary to garlic antibiotics for acne order colchicine online pills acute illness antibiotic 6 month old colchicine 0.5 mg visa, determine whether alcohol or other drugs were ingested antimicrobial impregnated catheters purchase colchicine online pills. At very low core temperatures antibiotic resistance related to natural selection purchase discount colchicine online, a number of serious arrhythmias can occur (heart block, J wave, atrial and ventricular fibrillation). Consequently, active treatment of the hypothermic patient should not be prematurely stopped. Failure to resuscitate until re-warming has been achieved could be viewed as a "failure to meet the standard of care". Explain the mechanism of body temperature homeostasis by describing the balance between heat production and heat loss including heat generation by cellular metabolism (heart and liver) and heat loss (skin and lungs). Include a description of the role of the hypothalamic response to cold stress in order to stimulate heat production (shivering, increased thyroid/catecholamine/adrenal activity). Define the various types of heat loss: evaporation, radiation, conduction, and convection (convective heat loss to cold air and conductive heat loss to water are the most common mechanisms of accidental hypothermia). Although not usually related to serious medical problems, in some it may interfere with daily activities, affect quality of life, and in a very few be indicative of serious organic disease. Psychogenic (anxiety, depression) Key Objectives 2 Interpret for patients with tinnitus that any condition of the ear associated with the ear canal (wax, otitis media), cochlear hearing loss, or central nervous system hearing loss can cause tinnitus. Objectives 2 Through efficient, focused, data gathering: ­ Determine whether or not the tinnitus is related to an ear condition or hearing loss. Explain that the perception of tinnitus is likely related to the loss of input to neurons in the central auditory pathways resulting in abnormal firing. They require evaluation in the emergency department for triage and prevention of further deterioration prior to transfer or discharge. Early recognition and management of complications along with aggressive treatment of underlying medical conditions are necessary to minimise morbidity and mortality in this patient population. Lacerations and wounds from other causes Key Objectives 2 Evaluate patient according to Advanced Trauma Life Support guidelines so that airway is established and breath sounds are evaluated, the cardiovascular status is stable and peripheral and central lines are secured, neurologic status is fully documented, and with the patient completely exposed (but temperature controlled), all evidence of external injury is evaluated (secondary survey). Objectives 2 Through efficient, focused, data gathering: ­ Elicit history from patient or collateral sources about past medical history, medications, allergies, and drug or alcohol use (present in over 30 % of patients admitted with complications of trauma). Briefly outline the process of cell division, regeneration and differentiation as it pertains to wound healing. Explain that shock is associated with systemic reduction in tissue perfusion, thereby resulting in decreased tissue oxygen delivery. Contrast pre-shock (warm or compensated shock) from distributive or low afterload shock. Rupture of a hollow viscus or bleeding from a solid organ may produce few clinical signs. Blunt trauma (generally leads to higher mortality rates than penetrating wounds) a. Missile wounds Key Objectives 2 In the emergency room a definitive diagnosis is seldom possible (especially with blunt trauma). Objectives 2 Through efficient, focused, data gathering: ­ Identify region(s) of the abdomen injured and use anatomical localization of organs in various areas to determine organs potentially injured; examine for tensely distended abdomen (potential for increased intra-abdominal pressure and abdominal compartment syndrome). Outline hemodynamic and other changes to be anticipated in a person with ongoing hidden blood loss. List physiologic considerations relevant to anemic patients important in deciding whether blood transfusion is indicated (degree to which oxygen delivery to tissues is adequate and compensatory mechanisms for maintaining oxygen delivery are overwhelmed or deleterious). Dog and cat bites account for about 1% of emergency visits, the majority in children. Insect bites in Canada most commonly cause a local inflammatory reaction that subsides within a few hours and is mostly a nuisance. In contrast, mosquitoes can transmit infectious disease to more than 700 million people in other geographic areas of the world. On the other hand, systemic reactions to insect bites are extremely rare compared with insect stings. The most common insects associated with systemic allergic reactions were blackflies, deerflies, and horseflies. Snake bites Key Objectives 2 Examine the patient completely to document the presence/absence of more than one wound. Objectives 2 Through efficient, focused, data gathering: ­ Elicit history from patient or family about type of animal, owner of animal, and review circumstances of attack, including whether the animal is available for observation. Detailed Objectives 2 Charter of Rights, statutes, regulations, by-laws, and the rulings of courts (the #common law#) are applicable in various ways to the practice of medicine and are binding on physicians. Physicians should consider potential medico-legal issues once treatment of patients with human bites (or animal) has been undertaken. Infection can complicate wounds received in fights/bites that can result in litigation involving both parties. Photographs of the injuries should be obtained at presentation and then throughout treatment. It may also be appropriate for the physicians to contact appropriate authorities such as law enforcement or employee health, depending upon the setting of the clash. Risk of blood-borne pathogen transmission should be analyzed and local regulations or laws should be consulted so that if appropriate, serologic screening of the individuals involved is undertaken. Individual case consideration should be made for screening all parties for serologic evidence of hepatitis B virus, hepatitis C virus, human immuno-deficiency virus, and syphilis. The physician may also be called upon to serve as an expert medical witness in the case. For example, hemodynamic stability takes precedence over fracture management, but an open fracture should be managed as soon as possible. On the other hand, management of many soft tissue injuries is facilitated by initial stabilization of bone or joint injury. Unexplained fractures in children should alert physicians to the possibility of abuse. Key Objectives 2 Reduce fracture so that normal alignment and length are restored and retain such reduction until healing occurs; encourage early restoration of function and continued rehabilitation. In either instance, emergency management becomes extremely important to the eventual outcome. Rib fracture Key Objectives 2 Since such patients frequently present in shock and/or respiratory distress, assess with urgency, resuscitate, and stabilize patient; suspicion of specific injury should lead to immediate diagnostic imaging/other investigative procedures. Objectives 2 Through efficient, focused, data gathering: ­ Elicit history of chest pain with latent period between injury and pain. The incidence is uncertain, but likely it may occur several hundred times more frequently than drowning deaths (150,000/year worldwide). Hypothermia Key Objectives 2 Explain that the differentiation between salt and fresh water near drowning is more apparent than real since the amount of water needed to be inhaled for such differences to occur is more than five times the amount inhaled in near drowning (3-4 ml/Kg). Objectives 2 Through efficient, focused, data gathering: ­ Determine which organs and the extent of dysfunction caused: pulmonary, neurologic, cardiovascular, plasma composition, renal function. Key Objectives 2 Assess and control vital functions (airway, breathing, and cardiovascular status) and give management priority to life threatening injuries. Definitive treatment of the facial trauma is relatively less urgent but of major cosmetic importance. Objectives 2 Through efficient, focused, data gathering: ­ Elicit a history about the nature of the injury. The ultimate function of the hand depends upon the quality of the initial care, the severity of the original injury and rehabilitation. Damage to bones and/or joints Key Objectives 2 Demonstrate the assessment of hand injuries. Objectives 2 Through efficient, focused, data gathering: ­ Elicit history of antecedent trauma and type, and assess the nature and extent of injury. Improved outcome after head trauma depends upon preventing deterioration and secondary brain injury. Objectives 2 Through efficient, focused, data gathering: ­ Elicit history on more than one occasion to detect change in mental status; ask about temporary loss of consciousness, vomiting, seizure, headache, lethargy, etc. This must include information regarding the nature of the proposed treatment or investigation, anticipated effects, material or significant risks, alternatives available, and any information regarding delegation of care, and will be given according to the circumstances of each particular case. The law regarding delegation of care is specific to each province and the physician should be fully aware of local requirement in this regard. An intoxicated patient with a large head laceration, the result of a fall down a flight of stairs, is examined and then prepared for suturing prior to further investigation. The patient admits to being unconscious for a period of time, and does not remember much of what happened prior to the fall except a considerable amount of alcohol being consumed at a party. As you warn the patient that the administration of local anesthetic will cause some discomfort, the patient sits up and decides to go home. After explaining your concern about possible serious head injury, the patient replies that the risks are understood, repeats the risks verbally, and is willing to accept the risks. List the secondary effects and respective mechanisms that may lead to brain injury in addition to head trauma. Evaluation of these injuries is based on an accurate knowledge of the anatomy and function of the nerve(s) involved. Laceration Key Objectives 2 Identify the peripheral nerve involved, the level and type of involvement. Objectives 2 Through efficient, focused, data gathering: ­ Elicit and interpret information from the history and physical examination to distinguish a peripheral nerve injury from other non-traumatic neuropathies or central lesions. Outline three mechanisms of nerve injury: traction injury, a direct blow or a percussive/contusion injury, nerve compression, and laceration or division. Since so many households include pets, dog and cat bites account for about 1% of emergency visits, the majority in children. Crush injuries (avulsions, bites, and crush injuries are usually "untidy" widespread tissue damage, severe or prolonged contamination) Key Objectives 2 Prior to wound closure, examine all patients thoroughly for evidence for injuries involving important underlying structures (tendon, nerve, vessel, foreign body). Objectives 2 Through efficient, focused, data gathering: ­ Elicit and interpret information from history and physical examination to determine the nature and severity of the skin wound, time since injury (>24 hours or<24 hours), presence of infection. The average age at the time of spinal injury is approximately 35 years, and men are four times more likely to be injured than are women. The sequelae of such events are dire in terms of effect on patient, family, and community. Spontaneous epidural hematoma Key Objectives 2 Contrast the impairment of ventilatory muscle strength in complete or incomplete cervical spinal cord injury, and explain the effect of denervation of abdominal musculature. Objectives 2 Through efficient, focused, data gathering: ­ Determine whether there is any impediment of respiratory function. Define spinal cord injuries as either complete or incomplete (complete injury occurs when functional motor output and sensory feedback are absent below the spinal cord injury level, while some neurological activity persists below the site of injury in the case of an incomplete injury. Ventilatory muscles innervated below the level of a complete spinal cord injury are completely nonfunctional, while the degree of ventilatory muscle compromise is variable in patients with incomplete injuries). Explain that the extent of ventilatory muscle impairment depends upon the degree and location of the spinal cord injury. Explain that spinal cord injury affects ventilatory control in that individuals with tetraplegia have blunted perceptions of dyspnea and an abnormally small increase in ventilatory drive in response to hypercapnia (ventilatory response to hypercapnia among quadriplegics was approximately one-fourth that of normal controls). Objectives 2 Through efficient, focused, data gathering: ­ Elicit history about the nature of the injury, difficulty voiding, and blood in urine or at meatus; differentiate straddle injury from sexual abuse (straddle injuries typically are unilateral and superficial and involve the anterior portion of the genitalia in both boys and girls). Foreign body Key Objectives 2 Provide initial management and obtain consultation when indicated. Objectives 2 Through efficient, focused, data gathering: ­ Elicit and interpret information from the history and physical examination to diagnose an arterial injury. Pain usually implies infection whereas difficulty is usually related to distal mechanical obstruction. Urinary frequency (normal or decreased volume) associated with dysuria and/or pyuria a. Irritable bladder (bladder dissynergia) Key Objectives 2 Differentiate between urinary tract infections and conditions outside the urinary tract with similar presentation; determine which infections require treatment, and select the appropriate treatment. Objectives 2 Through efficient, focused, data gathering: ­ Interpret urinalysis and clinical findings in order to diagnose problems external to urinary tract. Diabetes mellitus is a common disorder with morbidity and mortality that can be reduced by preventive measures. Urinary frequency (normal/decreased volume) associated with dysuria and/or pyuria Key Objectives 2 Evaluate diabetic patients and determine whether diabetic ketoacidosis or hypoglycemia is present; formulate a management plan for diabetic emergencies. Objectives 2 Through efficient, focused, data gathering: ­ Determine whether the obstruction is acute or chronic, duration, complete or partial, and unilateral or bilateral, and site. Contrast mechanism of hypertension in unilateral obstruction (vasoconstriction secondary to elevated rennin-angiotensin) to bilateral obstruction (volume expansion). Contrast the lack of hydronephrosis with obstruction within the first 1 3 days (the collecting system is relatively uncompliant) to that in more chronic obstruction (collecting system encased by retroperitoneal tumor or fibrosis). Amount or pattern is considered outside normal when it is associated with iron deficiency anemia, it lasts>7days, flow is>80ml/clots, or interval is<24 days. Neoplasms, malignant/benign (endometrial cancer, uterine sarcoma, fibroids, adenomyosis) B. Age related (immature hypothalamic-pituitary-ovarian axis, menopausal ovarian decline) ii. Drugs (hormone replacement, contraception, anticoagulants, chemotherapy, steroids) Key Objectives 2 Determine whether the patient is hemodynamically stable prior to any other task. Objectives 2 Through efficient, focused, data gathering: ­ Differentiate between bleeding related to or unrelated to pregnancy first. In a patient with vaginal bleeding, where sexual abuse is suspected, legal definitions may be needed. Victims should be asked to sign consent forms prior to collection of any samples for evidence. Such samples, if consent is given, should be collected at the time of the initial evaluation and stored securely even if the patient eventually decides against reporting the abuse. Contrast ovarian function during menstruation to peri-menopause/menopause (intermittent anovulation as ovarian function declines to chronic anovulatory cycles and progesterone deficiency with unopposed estrogen exposure). Desquamative inflammatory vaginitis/Focal vulvitis Key Objectives 2 Determine the appearance of the discharge, but state that appearance may be misleading, and up to 20% of patients may have two coexistent infections. Domestic violence is one of them, since it has both direct and indirect effects on the health of populations.
