Posted with permission from the September 2017 issue of Seminars in Cutaneous Medicine and Surgery. Eczema/dermatitis has the symptoms of itching, reddening, scaling, and edematous papules, and the condition progresses in a specific inflammatory reaction pattern. Eczema/dermatitis is histopathologically characterized by intercellular edema called spongiosis, which can be caused by extrinsic factors, such as irritants or allergens, or by intrinsic factors, such as atopic diathesis. These factors interact in complex ways, and extrinsic and intrinsic 7 factors are seen together in many cases. If the cause is not identified, eczema may be called acute, subacute or chronic, depending on the clinical and pathological features. Clinical features Itchy edematous erythema forms, on which papules and serous papules are produced. In the chronic stage, acanthosis, lichenification, pigmentation and depigmentation are found, in addition to the symptoms of the acute stage. Pathogenesis Both extrinsic and intrinsic factors are involved in eczema Clinical images are available in hardcopy only. When an extrinsic agent such as a drug, pollen, house dust, or bacteria invades the skin, an inflammatory reaction is induced to eliminate the foreign substance. The severity and type of reaction vary according to intrinsic factors such as seborrhea, dyshidrosis, atopic diathesis, and the health condition of the patient. Scaly erythema with scales, papules and vesicles are scattered, partly forming oozy phocytes and spongiotic bulla. Spongiosis and spongiotic bulla are less severe in chronic eczema than in acute eczema. These causes interact in complex ways and are not always clearly iden aa tifiable. Eczema with unidentified cause When the cause is not identified, eczema is simply called acute, subacute or chronic, according to the clinical findings, the course of the eruption, and the pathological findings. Hyperkeratosis, regular acanthosis and elongation of epidermal rete Contact dermatitis ridge are noted.

Eczema with unidentified cause is usually considered contact dermatitis with the involvement of an extrinsic substance. Topical steroids and oral antihistamines are applied as the first line of treatment for eczema at all stages. Acute eczema Acute eczema is accompanied by exudative erythema, edema, and sometimes vesicles (Fig. Subacute eczema Subacute eczema has a severity between that of acute and that of chronic. When acute eczema continues for more than one week after onset, it is likely to appear lichenified, and the diagnosis is chron Clinical images are available in hardcopy only. Contact dermatitis Outline Contact dermatitis is localized to the site of extrinsic stim ulation by foreign substance or allergic reaction. Dermatitis due to physical trauma, pharmacological action, irritation, sensitization, mediated by IgE and induced by light are described. Pseudophytodermatosis caused by plant-delivered elements is also described in the introduction to this work. Keywords: Allergy and immunology; Dermatitis; Plants; Skin diseases Resumo: As dermatoses causadas por plantas sao relativamente comuns no nosso meio e podem ocorrer por diversos mecanismos patogenicos. Sao descritas dermatoses por trauma fisico, por acao farmacologica, mediadas por IgE, por irritacao, por acao conjunta da luz e por sensibilizacao. Tambem sao descritas na introducao desta revisao as pseudofitodermatoses causadas por elementos veiculados pelas plantas e, por isso, aparentemente causadas pelas plantas. It is mainly caused by direct contact with the present in the plant, such as insecticides, agrotoxic plant, but it may occur without any direct contact or substances, and contaminated arthropods, such as the by association with sunlight. Therefore, it is interest hay itch mite (Pyemotes ventricosus or Pyemotes trit ing to note that substances produced by plants and ici), found in cereal and other vegetals. They cause capable of causing dermatosis may enter in contact extremely pruriginous skin rashes that often affect 3-5 with the skin without direct contact of the individual farmers, farm workers, veterinarians, and others. This is the case been commonly used in several cosmetic products and of most perfumes used as such or fragrances present topical sunscreens. For this reason, it has become an in cosmetic products and other products used for important sensitizing agent that may cause contact different purposes. Due to the fact that lichens attach not only Balsam of Peru, with substances such as eugenol, to humid rocks, but also to old tree trunks and vege isoeugenol, cinnamaldehyde, colophony, and tables, plants may be mistakenly blamed for causing 6,7 terebenthine, among others. Likewise, some cases of not predisposed, because the disease is triggered by paracoccidioidomycosis may have the etiologic agent the penetration of pharmacologically active (Paracoccidioidis brasiliensis) veiculated by vegetals, substances in the skin. The nettle, Urtica dioica or Urtica urens, a In spite of all the existing possibilities, the plant found in shrubbery close to trails frequented by most common form of phytodermatosis is contact men or other animals and even in gardens as weed, is dermatitis and the most frequent dermatologic symp capable of provoking papular-pruriginous lesions in tom is eczema. There is also contact with a they release their contents, composed by hystamine, plant-derived substance for ubiquitous use without serotonine, acetilcoline and other vasoactive direct contact with the originating plant. Proteins present in these plants trigger injure the skin upon direct contact, such as when this reaction, as already described in the case of plants are manipulated or by accident without skin contact with regular-use latex gloves by health protection. Atopic individuals are after small fractures or cuts in their structures, release predisposed to contact urticaria. Pruritus, irritants like sap, small prickles or even microscopic erythema, edema, and sometimes vesicles appear spicules or crystals that in contact with the skin may 30 minutes after contact. The list of plants, fruit, vegetals, and wood that In the cactaceae family there are several genera, may cause urticaria is very long because it is believed such as: Opuntia, Cereus, Cephalocereus, that all plants may provoke contact urticaria. Generally, this form of dermatitis affects food industry workers, cooks, 10 gardeners and florists. They contain calcium oxalate formed by caustic substances is enough to cause dermatitis. The fine needle bands grouped in compartments, degree of irritation depends on the substance, but the surrounded by a mucilaginous liquid. Climatic water and released from the compartments when in 12 factors that facilitate or reduce the penetration of contact with water or direct contact. They can lead Euphorbia milli (crown-of-thorns), Euphorbia to the formation of vesicles and blisters; because they pulcherrima (poinsettia), Euphorbia tirucali (pencil cause edema of the tongue, palate and mucous tree), Euphorbia cutinoides (assacui), Euphorbia membranes of the region, they lead to speaking cyparissias (cypress spurge) (Figure 1) belong to difficulties and are known as muting plants. They can cause lesions in the skin, eyelids and these are plants that resemble cacti and have eye, and irritation of the mucosa of the digestive tract inside a milky sap or latex that is highly irritant if ingested, which could more easily happen with 12 (euphorbine), formed by diterpene and phorbol esters, small children and animals. They are Narcissus pseudonarcissus), which contains calcium garden plants and because they have thorns some are oxalate in the bulbs. They species, such as the pencil tree, have their milky are highly cultivated in Europa and are used as irritating sap released when cattle or other animals ornamental and garden plants and in perfumery as a crush them and because of this are used as hedgerow. They may also In this family, there are plants like provoke subungueal hyperkeratosis. Clothes can Dieffenbachia picta (dumb cane), which is spread the narcisse bulb crystals to other areas of the commonly used as an ornamental plant. Tulips, besides cases of condylomata acuminata and warts, especially provoking dermatitis by irritation (despite not having due to its antimitotic activiy. It should be emphasized oxalate in their bulbs) may cause dermatitis by an that podophyllin can lead to toxic phenomena allergic mechanism, in the same way as Aloe Vera, depending on the amount absorbed. This irritative Many plants produce substances known as 12 capacity facilitates sensitization. It is known that pineapple been in contact with the plant and that have been can cause irritations in the mouth (stomatitis, exposed to sunlight. It often develops within 24 hours particularly angular cheilitis and perioral dermatitis). It may Thyme (Thymus vulgaris), an aromatic herb of evolve to a secondary infection, but the main the labiatae family used in culinary and in the characteristic of phytophotodermatosis is production of cosmetics and drugs, is described as a pigmentation that may last for several weeks. It Most plants that may cause provokes dermatitis by air dispersion probably phytophotodermatosis belong to the rutaceae, 15 through a primary irritation mechanism. Agave (Agave americana), used in the manufacturing of ropes, hammocks, and to tie other plants such as forage, often causes traumas to the skin. For example, the orange (Citrus sinensis), alopecia areata, but due to the great and variable lemon (Citrus limmonia), lime (Citrus medica), amount of psoralen, its prohibition has been tangerine (Citrus reticulata or Citrus nobilis) and recommended because cases of severe others such as the common rue (Ruta graveolens). The fact that the ficus tree is included in this family (Ficus lime juice is often squeezed on top of seafood on the carica). It is also important psoralens and has been used as a self-tanning 17 to remember that because the contact of the juice is adjuvant.

However, sesquiterpene It is interesting to note that tulipalin A, the lactones are tested because there are controversies quinone described as the allergen found in liliaceae regarding the role of sunlight in the allergic reaction (tulip) and alstroemeriaceae, does not show cross caused by this compound. It is more frequently found reactivity with sesquiterpene lactones (alpha-methyl 20-22 in plants of the asteraceae family.

Often, only one joint is involved (knee, was mild effusion and warmth on both sides of the knee joint. Probable cause: Exposure to pathogens in contaminated water or soil during his stay in Haiti. Radicular Pain Radicular pain results from direct irritation of axons of a spinal nerve or neurons in the dorsal root ganglion and is experienced in the musculoskeletal system in a dermatome, sclerotome, or myotome. More often the therapist sees a client who ating means the pain spreads or fans out from the originating describes pain that does not match a dermatomal or myoto point of pain. For example, the sion, referred pain results from activation of nociceptive free client who describes whole leg pain or whole leg numbness nerve endings (nociceptors) of the nervous system in somatic may be experiencing inappropriate illness behavior. Regional pain any component to pain is discussed in the section on Screening where near, around, or along the pathway of the sciatic nerve for Systemic Versus Psychogenic Symptoms. Pain arising from arteries, as with arteritis (infammation of Radiculopathy is another symptom that is separate from an artery), migraine, and vascular headaches, increases with radicular pain. Radiculopathy describes a neurologic state in systolic impulse so that any process associated with increased which conduction along a spinal nerve or its roots is blocked. Look for associated signs and whereas the weakness will present in a myotomal distribu symptoms of the cardiac or pulmonary systems.

Other complications including dehydration may also occur Persistent (Chronic) Diarrhoea: Last for 14 days or longer, the main danger is malnutrition and serious non-intestinal infections, dehydration may also occur Dirrhoea with Severe Malnutrition (Marasmus or Kwashiorkor): the main dangers are severe systemic infection, dehydration, heart failure, vitamin and mineral deficiency. Note: the basis for the management of each type of dirrhoea is to prevent or treat dangers that present. Management of diarrhea in adults the principles of management of diarrhea in adult are the same as in children in correction of fluid deficit. However, the most common cause for diarrhea in adult is food poisoning which is normally self-limiting. Treatment Guide: Correct volume status, electrolyte disturbances and vitamin deficiencies. They have in common the involvement of acid-pepsin in their pathogenesis leading to disruption of the mucosal integrity causing local defect or excavation due to active inflammation. Peptic ulcer may present in many different ways, the commonest is chronic, episodic pain present in many different ways, and may persist for months or years. However, the ulcer may come to attention as an acute episode with bleeding or perforation, with little or no previous history. As with duodenal ulcer, epigastric pain is the commonest symptom of gastric ulcer. Diagnosis Heartburn and regurgitation of sour material into the mouth are specific symptoms Symptoms for persistent disease may include odynophagia, dysphagia, weight loss and bleeding Extra esophageal manifestation are due to reflux of gastric contents into the pharynx, larynx, trachealbrochial tree, nose and mouth causing chronic cough, laryngitis, pharyngitis.

Correct severe thrombocytopenia with packed platelet concentrates, while overt coagulopathy should be corrected with fresh frozen plasma, and Vitamin K S. Non Pharmacological Endoscopy done within 24 hours could confirm diagnosis and provide sustained hemostasis control. Therapeutic modalities include variceal band ligation, Hemocliping, sclerotherapy, injectional tamponade therapy, thermocoagulation and angiographic embolization.

Note 55 | P a g e Correction of fluid deficit and/or blood is important in acute severe forms which may necessitates hospitalization Nutritional therapy should target to replenish specific nutrient deficits Life long surveillance is required due to risk of bowel cancer Use steroids only when the disease is confirmed, to avoid exacerbation of existing illness. Diagnosis Mainly abdominal pain and diarrhea; weight loss, anorexia, and fever may be seen Growth retardation in children Gross rectal bleeding or acute hemorrhage is uncommon Anemia is a common complication due to illeal disease involvement Small bowel obstruction, due to stricturing Perianal disease associated with fistulization Gastroduodenal involvement may be mistaken for H. Treatment Refer suspected cases to specialized centers for expertise management Baseline management as for Ulcerative Colitis above 2. Increasingly implicated as a significant cause of morbidity and mortality among hospitalized patients, C difficile colitis should also be recognized 56 | P a g e among outpatient populations. Prior antibiotic exposure remains the most significant risk factor for development of disease. Diagnosis Diarrhea and abdominal cramps occurs during first week, but can be delayed up to six weeks Nausea, fever, dehydration can accompany severe colitis Abdominal examination may reveal distension and tenderness. Note Stool examination is sensitive on anaerobic culture facilities which reveals toxigenic and non toxigenic strains Enzyme immunoassays are available for toxins A and B in stool Sigmoidoscopy is highly specific if lesion is seen but insensitive compared to the above. Diagnosis Abdominal discomfort of at least 3 months duration Bloating or feeling of distension Altered bowel habits (constipation and/or diarrhea) Exacerbations triggered by life events. Diagnostic Considerations Hematology and biochemistry studies Stool microscopy Colonoscopy with biopsy 57 | P a g e Treatment Refer patients to specialized centers for proper evaluation and management. Although presenting symptoms, such as diarrhea and weight loss may be common, the specific causes of malabsorption are usually established based on physiologic evaluations. The treatment often depends on the establishment of a definitive etiology for malabsorption. Etiologic examples include pancreatic insufficiency, bacterial overgrowth, celiac disease, tropical sprue, lactase deficiency, diabetic enteropathy, thyroid disease, radiation enteritis, gastrectomy and extensive small bowel resection. Diagnosis Depending on etiology, presentation may collectively include: Diarrhoea a commonest symptom which is frequently watery Steatorrhea due to fat malabsorption; characterized, by the passage of pale, bulky, and malodorous stools. Vitamin malabsorption can cause generalized motor weakness (pantothenic acid, vitamin D) or peripheral neuropathy (thiamine), a sense of loss for vibration and position (cobalamin), night blindness (vitamin A), and seizures (biotin). Treatment Patients should be referred to specialized centers for proper evaluation and definitive management Two basic principles underlie the management of patients with malabsorption, as follows: o the correction of nutritional deficiencies o When possible, the treatment of causative diseases Nutritional support o Supplementing various minerals, such as calcium, magnesium, iron, and vitamins, which may be deficient in malabsorption, is important o Caloric and protein replacement also is essential o Medium-chain triglycerides can be used as fat substitutes because they do not require micelle formation for absorption and their route of transport is portal rather than lymphatic o In severe intestinal disease, such as massive resection and extensive regional enteritis, parenteral nutrition may become necessary. It may present as acute pancreatitis, in which the pancreas can sometimes heal without any impairment of function or any morphologic changes, or as chronic pancreatitis, in which individuals suffer recurrent, intermittent attacks that contribute to the functional and morphologic loss of the gland. Common risk factors which trigger the acute episode are presence of gallstones and alcohol intake. Diagnosis Severe, unremitting epigastric pain, radiating to the back Nausea and vomiting 59 | P a g e Signs of shock may be present Ileus is also common Local complications: inflammatory mass, obstructive jaundice, gastric outlet obstruction Systemic complication: sepsis, acute respiratory distress syndrome, acute renal failure Diagnostic considerations Serum amylase, in counts over 1000U/L, but poor correlates with disease severity. Treatment Prompt referral to specialized centers with intensive care facilities is recommended Principles of management include expertise supportive therapy: o Nil per oral regimen for few days up to weeks is indicated depending on severity. The most common cause for such a condition is long-term excessive alcohol consumption. Diagnosis the most common symptom is upper abdominal pain that may be accompanied by nausea, vomiting and loss of appetite As the disease gets worse and more of the pancreas is destroyed, pain may actually become less severe During an attack, the pain often is made worse by drinking alcohol or eating a large meal high in fats. This can lead to weight loss, vitamin deficiencies, diarrhea and greasy, foul smelling stools. Once digestive problems are treated, patient will usually gain back weight and diarrhea improves. Another way is by giving the patient pancreatic supplements containing digestive enzymes. Acute peritonitis is most often infectious usually related to a perforated viscus (secondary peritonitis); primary or spontaneous peritonitis refers to when no intraabdominal source is identified. Acute peritonitis is associated with decreased intestinal motility, resulting in distention of the intestinal lumen with gas and fluid. The accumulation of fluid in the bowel together with the lack of oral intake leads to rapid intravascular depletion with effects on cardiac, renal, and other systems. Diagnosis Acute peritonitis is usually characterized by acute abdominal pain and tenderness, dehydration, fever, hypotension, nausea and vomiting and tachycardia. Bacterial translocation, bacteraemia and impaired antimicrobial activity contribute to its development. Antimicrobial therapy is adjunctive to surgical correction of underlying lesion or process and treatment will depend on causative agent. Referral Patient needs referral to centers where surgical intervention is adequate. Contributory factors may include inactivity, low fiber diet and inadequate water intake. Diagnosis Fewer than three bowel movements per week, small, hard, dry stools that is difficult or painful to pass, need to strain excessively to have a bowel movement, frequent use of enemas, laxatives or suppositories are characteristic. Referral the following signs and symptoms, if present, are grounds for urgent evaluation or referral: Rectal bleeding Abdominal pain Inability to pass flatus Vomiting Unexplained weight loss. Diagnostic guides: An extensive work up of the constipated patient is performed on an outpatient basis and usually occurs after approximately 3-6 months of failed medical management. Imaging studies are used to rule out acute processes that may be causing colonic ileus or to evaluate causes of chronic constipation. In the acute situation with a patient at low risk who usually is not constipated, no further evaluation is necessary. Consider sigmoidoscopy, colonoscopy, or barium enema for colorectal cancer screening in patients older than 50 years. The internal hemorrhoids are graded into four groups: Bleeding with defecation Prolapses with defecation but return naturally to their normal position Prolapses any time especially with defecation and can be replaced manually Permanently prolapsed. Diagnosis the most common presentation of hemorrhoids is rectal bleeding, pain, pruritus, or prolapse. However, these symptoms are nonspecific and may be seen in a number of anorectal diseases. A thorough history is needed to help narrow the differential diagnosis and adequate physical examination to confirm the diagnosis. V internal hemorrhoids or any incarcerated or gangrenous tissue requires prompt surgical consultation External hemorrhoid symptoms are generally divided into problems with acute thrombosis and hygiene/skin tag complaints. The former respond well to office excision (not enucleation), while operative resection is reserved for the latter. Drugs of choice Steroids and local anesthetics aims to reduce inflammation and provide relief during painful defication. Diagnosis the hall mark is severe sharp pain during and after defecation with/out bright red bleeding. Diagnostic consideration Perform digital rectal examination or protoscopy, which must be done with topical anesthesia. Treatment Guide Stools must be made soft and easy to pass; ensure high fluid intake, use osmotic laxatives such as Lactulose 20 mls 12 hrly (O) Topical anesthetics (Lidocaine jelly 2% applied 12 to 8 hrly anal area with frequent seat baths reduces sphincter spasm. At worst, anal itching causes intolerable discomfort that often is accompanied by burning and soreness. Causes include: Benign anorectal condition such as hemorrhoids or anal fissure Neoplasia such as anal cancer, pagets disease Dermatological disease. Hepatitis may occur with limited or no symptoms, but often leads to jaundice, anorexia and malaise. Hepatitis is acute when it lasts less than six months and chronic when it persists longer. A group of hepatotropic viruses cause most cases of hepatitis worldwide, but it can also be due to other viral infections. Diagnosis Acute infection with a hepatitis virus may result in conditions ranging from subclinical disease to self-limited symptomatic disease to fulminant hepatic failure. Collectively patients may develop fever, anorexia, malaise, jaundice, abdominal pain after specific incubation periods; and in severe forms signs of acute liver failure including altered consciousness may be present. Supportive management is all that is required during acute illness, except in fulminant cases where specific antiviral medication may be required. Note: Refer all cases of suspected Hepatitis to referral centers for expertise management. Notably disease chronicity can progress into liver cirrhosis and hepatocellular cancer in span of years if no early treatment is initiated. Diagnosis There is a wide clinical spectrum ranging from asymptomatic serum amino transaminases elevations to apparently acute and even fulminant hepatitis. C) in combination with Tabs Rebavirin 800mg/day (O) in devided dose for genotype 2&3 or 1000mg/day(O) in devided dose for genotype 1,4,5 up to 48 weeks. It is a histological diagnosis characterized by hepatic fibrosis and nodule formation. Depending on etiologic process the progression of liver injury to cirrhosis may occur over weeks to years. Clinical classification of the disease using Child Tourcotte Pugh score is used to determine a 1-year mortality and need for liver transplantation. Diagnostic features Include jaundice, hepatomegaly, ascites, features of increased estrogen levels in men, while in women there are features of increased androgen levels. Features of portal hypertension like splenomegaly, ascites, distended abdominal wall vessels and variceal bleeding are common. Treatment Guide In compensated cirrhosis: Treat the cause and associated complications. In decompensate cirrhosis: Treat specifically the manifestation of hepatic decompansation.

Others are cool peripheral extremities, puffy face, hands and feet (Myxedema), diffused alopecia (hair loss), bradycardia, peripheral odema, delayed tendon reflex relaxation, carpal tunnel syndrome and serous cavity effusions. Diseases of the thyroid gland are manifested by qualitative or quantitative alterations in hormone secretion or enlargement of the thyroid gland or both. Enlargement of the thyroid gland may result in normal increased, or decreased hormone secretion. Post thyroidectomy Iodine should be given daily indefinitely to prevent recurrence, following dosing schedule give above Physiological doses of iodine can be given even in pregnancy. It is actually necessary to provide the therapy to avoid iodine deficiency to the foetus Patients should continue taking iodized salt indefinitely (Ref. Hyperthyroidism is characterized by an increased metabolic rate, which causes weight loss, increased appetite, fatigue, emotional disturbances, heat intolerance, sweating, muscle weakness and diarrhea.

Pyruvate kinase deficiency c) Haemoglobin Abnormal haemoglobin such as HbS, C, Unstable Hb Clinical features the disease may occur at any age and sex Patient may present with symptom and features of Anaemia Symptoms are usually slow in onset however rapidly developing anaemia can occur Splenomegaly is common but no always observed Jaundice Treatment i. Immunosuppressive drugs for the patients who fail to respond to corticosteroids and splenectomy. Symptoms may include anaemia, dactylitis, recurrent infections, impaired growth and development. Crises Three distinct types of crises develop in patients with sickle cell disease Vaso-occlusive or painful crises are more common occurring with a frequency from almost daily to yearly. It is important to distinguish between painful crises and pain caused by another process Aplastic crises occurs when erythropoiesis is suppressed Sequestration crises occurs in children or occasional in adult with an enlarged spleen due to massive pooling of red cells in the spleen Treatment Guidelines Nonspecific measures A: Folic acid 5mg once daily Specific measures S: Hydroxyurea 15mg/kg/day. Maximum dose: 35mg/kg Management of Complication Patients undergoing vascular crises should be kept warm and given adequate hydration and pain control (Inj pethedine 100mg 6hrly, Oral morphine 5mg/kg) and oxygen Acute chest syndrome is a life threatening complication and empiric antibiotics should be given. Usually asymptomatic but liable to haemolysis if incriminated drugs or foods are taken. Treatment Guidelines Avoid incriminated agents/foods or drugs Transfusion of packed red blood cells in severe anaemia. Most frequent haemorrhage involves joints or muscles and bleeding parttens differ with age: Infants usually bleed into soft tissues ar from the mouth but as the boy grows, characterist joint bleeding becomes more common. Frequent spontaneous haemarthrosis factor is needed several times Moderate 2-5%of normal 1Haemorrhage secondary 0. Patients present with a history of easy bruising, menorrhagea, gum bleeding and spontaneous joint bleeding in severe form. In the acute form massive activation of coagulation does not allow time for compensatory increase in production of coagulant and anticoagulant factors. Patients present with bleeding manifestation, extensive organ dysfunction, shock, renal corticle ischemia, coma, delirium and focal neurological symptoms. Clinical feature for adult thrombocytopenia appears to be more common in young women than in young men but amoung older patients, the sex incidence may be equal. Most adult patient presents with a long history of purpura, menorrhagia, epistaxis and gingival haemorrhage. Treatment of Venous Thromboembolism Long term anticoagulation is required to prevent a frequency of symptomatic extension of thrombosis and/or recurrent venous thromboembolic events. Warfarin is started with initial heparin or clexane therapy and then overlapped for 4-5days. We will exclude maxillo-facial injuries and eye injuries from this discussion (Ref this to eye section). Mortality is increased if hypotension or airway/breathing problem is not adequately solved. Exclude fractures by performing appropriate X-rays Note Referral must not be delayed by waiting for a diagnosis if treatment is logistically impossible Closed injuries and fractures of long bones may be serious and damage blood vessels Contamination with dirt and soil complicates the outcome of treatment I. Maximum of 4 doses per 24 hours Plus S: Cloxacillin 500mg 6 hourly for 7 days Plus B: Tetanus prophylaxis: 0. In children less than 6 months calculate dose by weight Perform X-ray to rule out dislocations or sublaxations 2 Referral If Severe progressive pain. Hemorrhagic shock may ensue in situations involving multiple fractures or pelvic ring fractures. Paralysis may be associated, often been brought by improper transfer of the patient to the hospital. Thus lion, tiger, leopard, hyena, bear, elephant, hippopotamus, buffalo, wolf and wild pig are examples of the wild animals that have bitten man. Clinical features of these bites arise from the pathology inflicted by teeth, tusks, claws and horns. Severe facial and eye innuries are common and pneumothorax, hemothorax, bowel perofration and compound fractures have occurred. Treatment Emergency surgery is often needed Replace any blood lost Treat complications of injury. Symptoms:Most bites and stings result in pain, swelling, redness, and itching to the affected area Treatment and Management Treatment depends on the type of reaction Cleanse the area with soap and water to remove contaminated particlesleft behind by some insects Refrain from scratching because this may cause the skin to break down and an infection to form Treat itching at the site of the bite with antihistamine Give appropriate analgesics Where there is an anaphylactic reaction treat according to guideline. If area burnt is larger than 10% of body surface then this is extensive because of fluid loss, catabolism, anaemia and risk of secondary infection. In such cases refer to secondary or tertiary level health care centre Children give A: Paracetamol 10 mg/kg every 8 hours Plus C: Procaine Penicillin 0. Foreign bodies introduced through the mouth (or nose) may be arrested in the larynx, bronchial tree, oesophagus or stomach. Foreign bodies in the stomach rarely produce symptoms and active treatment is usaullynot required. Decision of treatment for carcinoma of the cervix is best done in hospital under specialist care. Primary prevention (screening) and early detection: Vaccination is now available Avoid early sex. Histology: Usually Adenocarcinoma Others: Clear cell, small cell carcinomas, sarcomas. Decision of treatment for the uterine carcinoma is best done in hospital under specialist care. Chemotherapy regimen for leiomyosarcoma: 2 S: Adriamycin 40mg/m single agent every 3 wks x 6. Decision of treatment for the vulvo-vaginal carcinoma is best done in hospital under specialist care. Regional/zonal or tertiary depending on treatment expertise Treatment: Predominantly surgical. Radiotherapy: Post operative radiotherapy is indicated for high risk recurrence (positive 265 | P a g e margins and nodal involvement). Referral: All patients must be referred to a gynecologist for evaluation and decision on mode of treatment. However increasing abdominal distension, palpable mass in the abdomen, pain and presence of ascites are all late signs. Histologies of epithelial tumours: Serous (cyst) adenoma, mucinous (cyst) adenoma, endometrioid adenocarcinoma, clear cell adenocarcinoma, granulosa cell tumour, theca cell tumour, sertoli-Leydig cell tumour, mixed tumours. Decision of treatment for malignant trophoblastic tumours is best done in hospital under specialist care. If total tumour removal is not possible, then maximum debulking (cyto-reductive) surgery should be done. Chemotherapy Adjuvant chemotherapy: Is indicated for all unfavourable histologies as well as advanced stages. The most common warning sign of skin cancer is a change in the appearance on exposed areas of the skin, such as a new growth or a sore that will not heal. Surgery: the aim of sugery is total local excision where possible; wide local excision and graft; amputation sometimes is required. Locally destructive methods such as curetting, desiccating or cryotherapy may be emplyted. Radiotherapy: Indication: Positive margin, high grade disease or inoperable tumour. Chemotherapy: S: Topical 5 fluorouracil for very superficial lesions or carcinoma in situ. Detection/Prevention: Frequent self-check or screening exercise and prompt treatment of early keratotic changes. Investigation: None or minimal if lesion is small Radiological: Chest x-ray in case of clinically suspected lung involvement or abdominal ultrasound in case of suspected liver metastases. Detection/Prevention: Frequent self-check or screening exercise and prompt treatment of naevus. May use large fractions: 30Gy/6F/1 wk Excision margins are involved or very close Palliative intent (brain mets, fungation or profuse bleeding, bone pain, etc) 2. Treatment: Chemotherapy: Adults: S: Adriamycin 40mg/sq m i/v D1 Plus S: Vincristine 1. Note: Sequential hemibody irradiation is sometimes necessary for aggressive disease. They may interfere with vital functions such as: Respiratory, swallowing, sight, speech and mastication. Important aetiological factors include excessive intake of tobacco either by smoking or chewing and alcohol intake (particularly spirits). Other features include: Non-healing ulcers, lymphadenopathy, hoarseness, pain and difficult in swallowing. Decisions of treatment for head and neck tumours are best discussed at Tumour board. Surgery: Partial or total laryngectomy is for advanced stages only where voice is compromised. Clinical features: Presence of a thyroid mass or scar, laryngeal nerve palsy, hoarseness, dyspnoea, dysphagia. Treatment Radioactive iodine ablation Further thyroxine replacement therapy (for life). Symptoms: Difficult in swallowing (dysphagia) is the commonest symptom which is associated with weight loss and poor performance status. Dilatation with or without intubation should always be considered to ensure continued ability to swallow. Look for pallor, weight loss, supraclavicular foss nodes, abdominal and rectal examination, epigastric mass, hepatomegally, periumbilical nodes.

It is important to avoid laryngoscopy and intubation during light anaesthesia erectile dysfunction melanoma buy malegra dxt plus 160mg free shipping, as this is likely to lead to severe bronchospasm erectile dysfunction keywords malegra dxt plus 160mg low price. Ketamine is quite suitable for intravenous induction because of its bronchodilator properties erectile dysfunction nitric oxide discount malegra dxt plus 160 mg on-line. Ether and halothane are both good bronchodilators impotence quotes discount malegra dxt plus master card, but ether has the advantage that impotence yoga pose 160 mg malegra dxt plus fast delivery, should bronchospasm develop impotence massage order discount malegra dxt plus on line, epinephrine (0. This would be very dangerous with halothane which sensitizes the heart to the dysrhythmic effects of catecholamines. Aminophylline (up to 250 mg for an adult by slow intravenous injection) can be used as an alternative to epinephrine if bronchospasm develops; it is compatible with any inhalational agent. At the end of any procedure that includes tracheal intubation, extubate with the patient in the lateral position and still deeply anaesthetized; the laryngeal stimulation might otherwise again provoke intense bronchospasm. Postoperatively, give oxygen at not more than 1 litre/minute via a nasal catheter. Be careful with opiates, as the patient may be unusually sensitive to respiratory depression. Make a full Low blood sugar is the main preoperative assessment, looking especially for symptoms and signs of intraoperative risk from peripheral vascular, cerebrovascular and coronary disease, all of which are diabetes Monitor blood sugar levels and common in patients with diabetes, as is chronic renal failure. In the short term, the only major theoretical risk is that undetected hypoglycaemia 13 might occur during anaesthesia. Most general anaesthetics, including ether, halothane and ketamine, cause a small and harmless rise in the blood sugar concentration and are therefore safe to use. Thiopental and nitrous oxide have little effect on the blood sugar concentration; no anaesthetic causes blood sugar to fall. As an alternative, if frequent blood sugar measurements are impossible: Put 10 International Units of soluble insulin into 500 ml of 10% glucose to which 1 g of potassium chloride (13 mmol) has been added Infuse this solution intravenously at 100 ml/hour for a normal-sized adult Continue with this regimen until the patient can eat again and then return to normal antidiabetic treatment. However, make regular checks of blood glucose concentration and change the regimen, if necessary. Note that, if glass infusion bottles are used, the dose of insulin will need to be increased by about 30%, as the glass adsorbs insulin. Where several patients are due to undergo surgery on a given day, diabetic patients should be first on the list, since this makes the timing and control of their insulin regimen much easier. Because certain drugs (notably chlorpropamide) have a very long duration of action, there is some risk of hypoglycaemia, so the blood sugar 13 concentration should be checked every few hours until the patient is able to eat again. If difficulties arise with these patients, it may be simpler to switch them temporarily to control with insulin, using the glucose plus insulin infusion regimen described above. Emergency surgery the diabetic patient requiring emergency surgery is rather different. If the diabetes is out of control, there is danger from both diabetes and the condition requiring surgery. The patient may well have: Severe volume depletion Acidosis Hyperglycaemia Severe potassium depletion Hyperosmolality Acute gastric dilatation. In these circumstances, medical resuscitation usually has priority over surgical need, since any kind of anaesthesia attempted before correction of the metabolic upset could rapidly prove fatal. Resuscitation will require large volumes of saline with potassium supplementation (under careful laboratory control). There is no point in giving much more than 4 International Units of insulin per hour, but levels must be maintained either by hourly intramuscular injections or by continuous intravenous infusion. If the need for surgery is urgent, use a conduction anaesthetic technique once the circulating volume has been fully restored. Before a general anaesthetic can be given, the potassium deficit and acidosis must also have been corrected, or life-threatening dysrhythmias are likely. The level of blood sugar is much less important; it is better left on the high side of normal. Because of the extra body mass, the cardiac output is greater than in a non-obese person; more work is also required during exertion, which places greater stress on the heart. The association of smoking, obesity and hypertension is often a fatal one, with or without anaesthesia. A fat neck makes airway control and intubation difficult and excess subcutaneous fat leads to difficulty with venepuncture and conduction anaesthesia. Where blood supplies are scarce or unsafe, it may be possible to use pre-donation by the patient in elective cases or to use autologous transfusion in emergencies. Minimize the risk of transmission of infection: Never leave syringes attached to needles that have been used on a patient For intravenous injections, use plastic infusion cannulae with injection ports that do not require the use of a needle, wherever possible Ensure that blood spills are immediately and safely dealt with Use gloves for all procedures where blood or other body fluids may be spilled Where blood spillage is likely, use waterproof aprons or gowns and eye protection. The aim is to provide a starting anaesthesia pleasant induction and lack of awareness for the patient, using a technique Never use an unfamiliar that is safe and that provides good operating conditions. Unfortunately, the anaesthetic technique in an ideal anaesthetic drug with all the desired qualities does not exist. It is common emergency Always check your equipment practice, therefore, to combine several drugs, each of which provides a single Make sure you have an component of anaesthesia. In contrast, ether produces a mixture of sleep, analgesia and relaxation but, because of its pungent smell and high solubility in blood, it is rather inconvenient and slow (though safe) for induction of anaesthesia. The muscle relaxants produce muscular relaxation alone and may therefore be used to provide good surgical relaxation during light anaesthesia, allowing the patient to recover rapidly at the end of anaesthesia. Opiate drugs, such as morphine and pethidine, produce analgesia with little change in muscle tone or level of consciousness. The choice of the most suitable combination for any given patient and operation calls for careful thought and planning. Before starting, check that you have the correct patient scheduled for the correct operation on the correct side. The surgeon should mark the operation site with an indelible marker before the patient comes to the operating room. Check that the patient has been properly prepared for the operation and has had no food or drink for the appropriate period of time. It is normal to withhold solid food for six hours preoperatively, but a milk feed can be given to babies up to three hours preoperatively. Clear fluids are regarded as safe up to two hours preoperatively if gastric function is normal. Make sure that: All the apparatus you intend to use, or might need, is available and working If you are using compressed gases, there is enough gas and a reserve oxygen cylinder the anaesthetic vaporizers are connected the breathing system that delivers gas to the patient is securely and correctly assembled Breathing circuits are clean Resuscitation apparatus is present and working Laryngoscope, tracheal tubes and suction apparatus are ready and have been decontaminated Needles and syringes are sterile: never use the same syringe or needle for more than one patient Drugs you intend to use are drawn up into labelled syringes Any other drugs you might need are in the room. Always begin your anaesthetic with the patient lying on a table or trolley that can be rapidly tilted into a head-down position in case of sudden hypotension or vomiting. It will be the technique of choice in many cases, but care is always needed as it is relatively easy to give an overdose or to stop the patient from breathing. If breathing stops, the patient may die unless you can easily ventilate the lungs with a face mask or tracheal tube. The first rule of intravenous induction is that it must never be used in a patient whose airway is likely to be difficult to manage. Intravenous induction will also suddenly reveal any pre-existing dehydration, hypovolaemia or hypotension. These conditions must be corrected preoperatively or there will be a dangerous fall in blood pressure on injection of the drug. Thiopental Thiopental is presented as ampoules of yellow powder that must be dissolved before use in sterile distilled water or saline to make a solution of 2. Higher concentrations are dangerous, especially if accidentally injected outside a vein, and should not be used. The average sleep dose in a healthy adult is 5 mg/kg of body weight, but much less (2 mg/kg) is needed in sick patients. If the patient reports pain, stop injecting immediately because the needle is probably outside the vein and may even have entered an artery. Avoid injection into the elbow, if possible, because it is easy to enter the brachial artery by mistake. Propofol Propofol is a recently introduced, intravenous anaesthetic that can be used for induction of anaesthesia. Injection is often painful 14 unless a small amount of lidocaine (20 mg of lidocaine in 200 mg of propofol) is added just before injection. Patients are much less drowsy postoperatively; this is an advantage if they have to leave hospital the same day. To avoid bacterial contamination, ampoules must be used immediately after being opened. Ketamine Induction with ketamine is similar in principle to induction with thiopental and the same precautions apply. The eyes may remain open, but the patient will no longer respond to your voice or command or to painful stimuli. If you try to insert an oropharyngeal airway at this stage, the patient will probably spit it out. Muscle tone in the jaw is usually well maintained after ketamine has been given, as is the cough reflex. A safe airway is not guaranteed since, if regurgitation or vomiting of gastric contents occurs, there is still severe danger of aspiration into the lungs. After induction with ketamine, you may choose to proceed to a conventional inhalational anaesthetic, with or without relaxants and intubation. For short procedures, increments of ketamine may be given intravenously or intramuscularly every few minutes to prevent the patient responding to painful stimulation. If your supplies are limited, try to reserve ketamine for cases where there are few suitable alternatives; for example, for short procedures in children when access to the airway may be difficult. Suxamethonium Suxamethonium is a depolarizing, short-acting muscle relaxant which is widely used to facilitate intubation, especially for emergencies. Other non-depolarizing relaxants have a longer duration of action and generally require specialist skills to be safe. At 8 mg/kg of body weight, ketamine produces a marked increase in salivary secretions. If you use intramuscular ketamine, give atropine (which can be mixed with the ketamine) to prevent excessive salivation. Further doses of ketamine can be given intramuscularly or intravenously, as required. If ketamine is used as the sole anaesthetic agent, patients sometimes complain afterwards of vivid dreams and hallucinations; giving diazepam either before or at the end of anaesthesia can reduce these. They do not occur if ketamine is used only for induction and is followed by a conventional anaesthetic. There are two different systems available for delivering anaesthetic gases and vapours to the patient: Draw-over system: uses air as the carrier gas with added volatile agents or compressed medical gases Continuous-flow system: compressed medical gases (which must have a minimum of 30% oxygen) pass through flow meters and vaporizers to supply anaesthetic to the patient. The draw-over system is capable of producing first-class anaesthetic and surgical conditions. Modern draw-over apparatus has proved extremely reliable, easy to understand and maintain and economical in use. However, some small hospitals, and many larger ones, are equipped with continuous-flow machines. In contrast, inhalational induction can proceed only if the patient has a clear airway down which the anaesthetic can pass. If the airway becomes obstructed, the patient will stop taking up further anaesthetic and redistribution of the drug in the body will 14 lighten the anaesthesia. Inhalational induction is also preferred by some children who may object to needles. Practise regularly; it is simple and requires only patience, care and observation. Either draw-over or continuous-flow apparatus can be used for inhalational induction (Figure 14.
