Current recommendations are to combine this laboratory cles become trapped in the pulmonary capillary bed. The one exception would be in the monary arterial obstruction, whereas a pulmonary face of a low clinical pretest probability, when the finding of a embolism occluding a pulmonary artery will result in a per low D-dimer may be enough to exclude venous thromboem fusion defect. Lastly, D-dimer is of limited use in a number of result from other causes, including focal vasoconstriction clinical scenarios, which are associated with elevated D-dimer accompanying atelectasis, pneumonia, or bronchospasm. The perfusion and ventilation scans are then Elevation in cardiac troponins in the setting of an acute compared. A sufficiently large perfusion defect without a cor pulmonary embolism has been described. In patients with responding ventilation defect in the same area (ie, mis either a moderate or large pulmonary embolism, troponin T matched defect) generally is considered supportive of the (TnT) levels greater than 0. None of the patients with small emboli matched ventilation-perfusion defect generally is considered had an elevation of this cardiac marker. In another study, indeterminate and not helpful in making the diagnosis of tropoinin I (TnI) levels greater than 0. It is thought that the By convention, ventilation-perfusion lung scans are inter strain on the right ventricle from the increased pulmonary preted as normal (no perfusion defects), low or high proba arterial resistance in the face of an acute embolism leads to bility for pulmonary embolism, or intermediate probability the right ventricular myocardial ischemia in these patients (sometimes called indeterminate) for pulmonary embolism. Unfortunately, Limited number of large or moderate perfusion defects with only 41% of cases of pulmonary embolism had high matching ventilation defects (with normal or mildly abnormal probability lung scans, whereas 42% had intermediate chest x-ray) Intermediate probability probability scans and 17% had low-probability scans. Thus high-probability lung scans effec tively predict pulmonary embolism, whereas a normal scan (no for pulmonary embolism. Unfortunately, the majority of patients a modified summary of lung scan categories and criteria suspected of having pulmonary embolism fall into intermediate used in 931 patients included in this study. For a patient with suspected pulmonary embolism, estimate pretest probability (clinical information or clinical information plus results of prior tests). Look up posttest probability at intersection of pretest probability (column) and test result (row). Pretest Probability8% 28% 50% 74% Ventilation-Perfusion Radionuclide Scan Scan Result Sensitivity Specificity Likelihood Ratio Posttest Probability High probability 41% 97% 17. It should be embolism without treatment during long-term follow-up or emphasized that these studies have characterized mostly patients at autopsy. This approach would be ideal if it were not for who were not critically ill, in whom the appropriate studies could problems encountered with obtaining pulmonary angiogra be performed and compared. The traditionally used strategy is to perform pressure reduce the frequency of complications from pul pulmonary angiography for all suspected patients in whom monary angiography. A normal pulmonary hematoma requiring transfusion, are reported to occur in angiogram is quite accurate in excluding pulmonary up to 4% of critically ill patients undergoing pulmonary embolism, with fewer than 1% of patients with negative pul angiography. If not, further studies are required (eg, compression ultrasonography or pulmonary angiography) until a decision can be reached. Any decision to begin or withhold treatment must take into account the risk of treatment compared with the potential benefits of treatment. Inthe major disadvantage of this approach is that a large num addition, patients being considered for therapy other than ber of patients would require pulmonary angiography anticoagulation, such as thrombolytic therapy, cannot be because of abnormal but nondiagnostic lung scans. Proximal vein deep venous thrombosis is found evaluated using this strategy, the 3-month risk of developing an on initial testing in about 50% of patients with pulmonary embolic event without therapy if none of these studies revealed embolism. In patients with low or intermediate-probability venous thromboembolism was only 1. In general, the diag ventilation-perfusion lung scans but with high or uncertain nostic protocols that combine these noninvasive studies either clinical probability of pulmonary embolism, compression have obtained all studies during the initial assessment and made ultrasonography or impedance plethysmography may be treatment decisions based on all study results altogether or have performed. A combination of high or uncertain clinical sus obtained a single study at a time and continue to obtain addi picion, abnormal (but not high-probability) lung scan, and tional diagnostic data if the results are not conclusive until a positive noninvasive test for deep venous thrombosis definitive diagnosis is obtained or excluded. The attempt to assess the pulmonary vasculature bed directly have absence of evidence of deep venous thrombosis, however, been evaluated for their role in the diagnostic workup of pul should not rule out pulmonary embolism because the false monary thromboembolism. The combination of lung scan pulmonary emboli in the main, lobar, and segmental pul and noninvasive deep venous thrombosis studies decreases monary arteries. The lower sensitivity of this imaging study the number of pulmonary angiograms needed in these results in part from the poor performance in the diagnosis of patients from about 72% to 33%. The clinical impact of emboli in these strategies for selected patients also have been proposed. In subsegmental arteries is unclear, and they may not pose the patients suspected of pulmonary embolism who have abnor same morbidity and mortality risks as emboli in larger seg mal but nondiagnostic lung scans (ie, low or intermediate ments. However, in patients with a limited cardiopulmonary probability) and adequate cardiopulmonary reserve (eg, lack reserve, emboli in subsegmental arteries potentially could be of respiratory failure, hypotension, severe underlying lung devastating. If evidence of deep venous thrombosis is of these imaging studies is their ability to provide additional found initially or subsequently, treatment is started. In a study of 627 untreated patients with sus imaging requires the administration of intravenous contrast pected pulmonary embolism with nondiagnostic lung scans material and a degree of patient cooperation with the ability to and negative serial impedance plethysmographic studies over lie still and breath-hold for approximately 25 seconds in some 2 weeks, pulmonary thromboembolism occurred in only protocols to obtain good-quality pictures of the vasculature. Treatment therefore can be In a small but important proportion of studies, the results are withheld in this group of patients with acceptable results. In not acceptable because of movement artifacts or inadequate fact, this approach clarifies the natural history of pulmonary concentration of contrast material in the pulmonary arteries. A meta-analysis evaluated the 3-month clinical another diagnostic test is applied. If posttest probability is sufficiently high to jus can be used to diagnose pulmonary thromboembolism if a tify starting treatment or sufficiently low to justify withhold thrombus is seen but may not be able to exclude significant ing treatment, further diagnostic tests are not indicated. Oral anticoagulant agents, mainly in the form the pelvis and lower extremity also may have a future role in of vitamin K antagonists such as warfarin, are given for a the workup of this disease. There are a number of other treat vasculature would be the avoidance of iodine-based contrast ment schedules depending on the underlying cause of the material and its associated risks, including anaphylactic reac event, the history of previous thromboembolic events, and tions and renal impairment. Heparin also should be started once a pretest probability based on symptoms and signs and then diagnosis of deep venous thrombosis or pulmonary apply tests that increase or decrease the probability of disease embolism is confirmed, if not started prior to the diagnosis. In this way, the likelihood of pul Anticoagulants do not directly affect existing thrombi, but if monary embolism can be estimated and the risks of treat given in sufficient amounts, they can prevent further clot ment compared. In the absence of contraindications, initial treatment Validation of these data confirmed that these groups had 8%, should be with heparin in the form of continuous intra 28%, and 74% likelihood of pulmonary embolism. Sensitivity, specificity, likelihood ratios, and posttest probabilities of pulmonary embolism from selected studies of compression ultrasonography and D-dimer. Instructions: For a patient with suspected pulmonary embolism, estimate pretest probability and find posttest probability at intersection of pretest probability (columns) and test results (rows). For a 60-kg adult, this Standard heparin dose-adjustment protocols or nomo corresponds to 4800 units as a bolus followed by 1080 units/h grams for deep venous thrombosis and pulmonary or about 26,000 units/day. These heparin fractions twice-weekly measurements followed by weekly measure have greater bioavailability when given subcutaneously, ments should be adequate. A number of drugs interact with longer duration of action, allowing for once or twice-daily warfarin, both increasing and decreasing its effectiveness. On the other hand, barbi and cannot be used as an alternative form of anticoagulation turates, rifampin, and carbamazepine may reduce the effect in patients with heparin-induced thrombocytopenia syn of warfarin on the prothrombin time by increasing the rate drome. For patients with In addition to heparin, warfarin can be started on day 1 a first episode of idiopathic venous thromboembolism (no unless there are contraindications to its use. On the other hand, patients in coagulation factors, becomes an effective anticoagulant only whom risk factors are long term and poorly reversible, such after disappearance of previously synthesized circulating as those with chronic congestive heart failure or hypercoagu coagulation factors. Thus several days are needed for war lable states, should receive a longer period of anticoagulation farin to have an antithrombotic effect, whereas its anticoag therapy on the order of 12 months or even indefinitely. In the past, concern has been patients with a hypercoagulable state associated with malig raised about a potential hypercoagulable state induced by nancy, the effectiveness of anticoagulation is highly variable. This occurring in approximately 5% of patients (ranges from 1% in corresponds roughly to a prolongation of the prothrom those with low risk for bleeding to 10% in those with high risk). Warfarin and venous thrombosis, especially in patients with extensive other oral anticoagulant agents are also associated with bleed iliofemoral thrombosis with limb threat owing to vascular ing complications. Bleeding has been demonstrated to be less occlusion, is an approved indication for the use of throm common when excessively prolonged coagulation times are bolytic agents according to the 2004 American College of avoided. However, thrombolytic therapy should Patients who use a protamine-based insulin preparation, have be individualized and is not currently recommended as rou undergone a vasectomy, or have known hypersensitivity to fish tine therapy for deep vein thrombosis. Despite these results, many physicians venous infusion of vitamin K supplemented with factor believe that the benefits of thrombolytic therapy over antico replacement (eg, fresh-frozen plasma or prothrombin com agulation alone are not clear for patients with pulmonary plex concentrate). Thus the vast majority of patients are treated with state may be difficult and prolonged if too much vitamin K is heparin and oral anticoagulation alone. Rather than the size of the radio disease that is associated with both bleeding and venous and graphic occlusion itself defining a massive pulmonary arterial thrombotic complications. This syndrome should be embolism, this syndrome is now defined by the presence of suspected when the platelet count falls precipitously in a severe hemodynamic compromise with hypotension, shock, patient receiving any form of heparin. Treatment of this syndrome includes have shown faster lysis of clot in the pulmonary circulation, immediate discontinuation of all forms of heparin adminis reduction of pulmonary artery pressure, and improved cardiac tration, including intravenous flushes. If anticoagulation is output with the combination of thrombolytic agent and still necessary for the patients primary disease process, direct heparin compared with heparin alone. However, a survival thrombin inhibitors (eg, lepirudin, bivalirudin, and arga benefit has not been clearly established with this therapy and troban) or heparinoids (eg, danaparoid) can be used. It may also be a consideration in patients with future as more evidence becomes available. Warfarin should submassive embolism who show evidence of right ventric not be used alone. Another echocardiographic finding tokinase, but clinical bleeding so far has been found to be that has been found to have a high specificity in the diagnosis similar for all three agents. However, one analysis found that the fre strated a slight reduction in early symptomatic or asympto quency of major bleeding averaged 14% in patients who matic pulmonary embolism. There was no effect on received tissue plasminogen activator after pulmonary mortality. These authors suggested main indications have evolved for interruption of the infe that it would be safer to avoid pulmonary angiography for rior vena cava in patients with deep venous thrombosis and patients chosen to receive thrombolytics who have positive pulmonary embolism. A comparison of relative risks may prove likelihood of bleeding prior to anticoagulation or moderate useful in making decisions about pulmonary angiography to severe bleeding during heparin therapy. In addition, streptoki coagulation to prevent recurrent pulmonary embolism nase has been associated with allergic reactions given its anti despite an adequate dose and duration of therapy. However, genic properties and cannot be administered more than once early embolism after initiation of heparin generally should in a 6-month period. Heparin should be discontinued before starting pulmonary reserves are so low that even a single small pul thrombolytic agents; antiplatelet agents should not be given monary thromboembolus may be life-threatening. Urokinase and streptokinase are coming from deep veins that flow into that vessel. If an upper extremity is identified as the bed rest, immobility, central venous catheterization, critical continued source of emboli, some centers are capable of illness, or trauma. If the filter is placed because of a contraindication with thrombus formation either by preventing the platelet for or adverse reaction to anticoagulation, anticoagulation nidus from forming or by preventing activation of the coagu therapy is not given. The type of preventive therapy is closely linked emboli after interruption of the vena cava with this device to the underlying condition and the bleeding risk. Other reported problems include procedural ple,patients at moderate risk (eg, minor surgery with additional complications, filter malposition and migration, caval risk factors or aged 40 to 60 years with no additional risks) occlusion, and sepsis owing to device infection. Severe respiratory dis prolonged, and there is little increased risk of bleeding. Some patients may have laxis of deep venous thrombosis in a number of clinical bronchospasm that benefits from bronchodilators. Warfarin is effective in certain clinical situations Hemodynamic compromise in pulmonary embolism usually and, for example, is one of the choices for prophylactic treat indicates severe obstruction of the pulmonary circulation ment for patients with hip fractures as well as elective hip with failure of the right ventricle. However, volume overexpansion pentasaccharide that selectively inhibits factor Xa activity, can lead to increasing right ventricular myocardial oxygen has been shown to be highly efficacious in the prevention of consumption and subsequent ischemia and deterioration of deep vein thrombosis primarily in large orthopedic surgical function. Finally, mechanical methods of prophylaxis with grad little value in severe hemodynamic compromise, but uated compression stockings or external compression of the dopamine, dobutamine, and norepinephrine may be tried. These devices can be combined with Prevention of deep venous thrombosis and thereby of pul pharmacologic means of prophylaxis in very high-risk monary embolism has become a major goal in the manage patients or used alone in patients at risk of bleeding compli ment of critically ill patients who are at high risk of cations from medical therapy. External pneumatic compression of the ated with malignancy, prior venous thromboembolic disease, legs is effective in these patients. Abnormal pul patients with heparin-induced thrombocytopenia also monary gas exchange and hemodynamic compromise result should be considered for prevention of deep venous throm ing from new pulmonary emboli may not be identified in bosis by pneumatic compression devices. Again, this may be deep venous thrombosis in some of these patients, it is less difficult for critically ill patients to perform. Adjunctive prophylaxis Patients with worsening hypoxemia or increased physio with mechanical devices such as elastic stockings and inter logic dead space, increased pulmonary artery pressure (in the mittent pneumatic compression devices can add additional absence of other causes), unexplained tachycardia or benefit with little risk. The duration of prophylaxis, espe hypotension, or other features of unclear cardiopulmonary cially in this orthopedic patient population, is being inves insufficiency should be suspected of having pulmonary tigated. There is some evidence that extending the period of thromboembolic disease until proven otherwise. Four studies evaluating mal perfusion scan was highly predictive of a normal pul high-risk surgical patients without current evidence of deep monary angiogram. The authors of the study concluded head or spinal cord trauma, pelvic or lower extremity frac that ventilation-perfusion lung scans were helpful only if tures, prolonged immobility, and mechanical ventilatory sup they were high-probability or normal. This means of prophylaxis has not been studied in direct cluded, sufficient clinical suspicion should lead to pul comparison with heparin or mechanical devices.

The life expectancy in the country is improving, while the country is developing at a rapid pace. This has resulted in people living more years and at the time adopting lifestyles that have negative impacts on their health. This increase in diabetes and other non communicable diseases has given rise to a double burden of communicable and non-communicable diseases in Kenya. Diabetes and other non-communicable disease are now a threat to national development as they ofen result in long standing complications that are usually very costly to treat. They progressively drain the strength and resources of an individual rendering them unproductive and poor. This burden is in most cases passed on to families and the community with untold retardation of economic progress and eventually exacerbating poverty. In response to this crisis, the Ministries of Health in collaboration with Non-Governmental Organizations, Regional and International Diabetes Support Bodies spearheaded the National Guidelines for the Management of Diabetes Mellitus in order to provide a standardized way of managing diabetes in the country. Tese Guidelines are a synthesis of information drawn from an extensive review of local and international knowledge and experience. The Guidelines are suitable for use by all health workers and health institutions from both the public and privates sectors. They give clear directions on what needs to be done for people living with diabetes and provide a guide on the continuum of care required through out the life course of the individuals with diabetes. The successful implementation and strict adoption of these guidelines will require the partnership of the care providers and people living with diabetes mellitus. A coordinated efort is required from health professions in many disciplines to ensure a multidisciplinary approach to diabetes management. This will eventually improve the care provided to people with diabetes which will eventually improve their quality of life. This results from lack of insulin in the body or failure of body cells to respond to circulating insulin. Persistent hyperglycaemia results in progressive multiple organ damage giving rise to both acute and chronic complications. Diabetes Mellitus ofen goes undiagnosed because many of its symptoms though serious are ofen missed or are treated as common ailments. Recent studies indicate that the early detection of diabetes symptoms and treatment can decrease the chance of developing the complications of diabetes. The overall goal of diabetes management is to help individuals with diabetes and their families gain the necessary knowledge life skills, resources, and support them to achieve optimal health. The National Clinical Guidelines for the Management of Diabetes Mellitus ofers a step by step help to health workers to provide this optimal care. The recommendations on these guidelines are based on local and internationally sound best practices and provide up to date instructions and recommendations to all health workers when diagnosing and planning treatment for a person with diabetes mellitus. To implement these guidelines in the best way, each health facility or care provider must embrace the multidisciplinary approach to diabetes care and management. Tere is need for management of diabetes to be patient centered and provided in a more comprehensive way which not only involves blood sugar control but also looking at the patient in a holistic manner. The strict adherence to these guidelines will also stimulate policy changes that will ensure availability of essential drugs and medical supplies for diabetes are secured and made afordable and accessible to all who need them. Periodic reviews of the Guidelines will be necessary to accommodate new information as it becomes available from time to time. O Otieno Kenyatta National Hospital Scholastica Mwende Ministry of Public Health and Sanitation Zachary M. Ndegwa Ministry of Public Health and Sanitation Atieno Jalango Diabetes Kenya Association Eva Muchemi Kenya Diabetes Management and Information Centre Dr. Nato of the World Health Organization, Kenya Country Ofce provided technical advice to the drafing team. The development of the guidelines was carried out under the auspices of the Division of Non-communicable Diseases. Diabetes is one of the leading causes of blindness, renal failure and lower limb amputation. It also triggers cardiovascular disease which is the leading cause of deaths in diabetes patients. Tese changes are most likely to occur with implementation of a coordinated range of interventions to encourage individuals to maintain a healthy weight, participate in daily physical activity, and consume a healthy diet. It is more efective when provided through multiple methods and sites, such as schools, workplaces, mass media, and health centers. When prevention does not stop the occurrence of diseases, there is need for the health care services to provide quality care for people with diabetes. Improvement of care involves improvement of skills of health care providers, provision of requisite tools and regular supply of drugs and other medical supplies. The purpose of these Guidelines is to: Provide simple and practical ways to assess persons with diabetes and make the right diagnosis and provide the best treatment and care. It emphasizes the need for stepwise consideration when instituting treatment and need for referral of complicated cases. The chapter overemphasis on the management of diabetes ketoacidosis which is a major medical emergency with high mortality rate if not managed well. Tese include pregnancy, sick days, fasting, sports and travelling for people with diabetes. But these changes dont mean one wont be able to succeed at work or enjoy a healthy and fulflling life. In order to scale up and standardize the management of diabetes the implementation of this guideline is very critical. This calls for wide dissemination of the guideline and its acceptance and introduction into all health facilities in this country whether public, private for no-proft or private for proft. Its application will provide all the relevant information that will guide future revisions of the guidelines to suit the national needs for diabetes management. It is associated with acute complications such as ketoacidosis and hypoglycaemia, as well as long-term complications afecting the eyes, kidneys, feet, nerves, brain, heart and blood vessels. Misclassifcation of patients as Type 1 is probably relatively common and being treated with insulin is not the same as having Type 1 diabetes. Type 2 diabetes Most patients present with the classical symptoms of diabetes, including polyuria, polydypsia and polyphagia. Additionally, some patients present with sepsis, and/ or diabetic coma (hyperosmolar non-ketotic states). The patients usually do not seek early medical attention because of the insidious onset of the disease and therefore may present at diagnosis with features of diabetic complications, including visual difculties from retinopathy, pain and/or tingling in the feet from neuropathy, foot ulcerations, impotence and stroke. Some elderly Type 2 patients present with hyperosmolar non-ketotic coma that has a high mortality. It also reverts to metabolic and clinical normality post-partum, though relative risks of later Type 2 diabetes is between 7 13 times high in women with gestational diabetes compared to normo-glycaemic ones. Particular adverse efects include, eclampsia, birth difculties, intra-uterine growth retardation, foetal macrosomia, neonatal hypoglycaemia and respiratory distress. However, it may pose a problem for those with a minor degree of hyperglycaemia, and in asymptomatic subjects. In these circumstances, two abnormal blood glucose results on separate occasions are needed to make the diagnosis. If such samples fail to confrm the diagnosis it will usually be advisable to maintain surveillance with periodic retesting until the diagnostic situation becomes clear. The clinician should take into consideration additional risk factors for diabetes before deciding on a diagnostic or therapeutic course of action. The diagnosis of diabetes must be confrmed biochemically prior to initiation of any therapy, The presence of symptoms of hyperglycaemia, such as polyuria, polydypsia, pruritus vulvae, lethargy, loss of weight and a random capillary whole blood glucose equal or above 11. In asymptomatic subjects a single abnormal blood glucose result is inadequate to make a diagnosis of diabetes. The abnormal value must be confrmed at the earliest possible date using any of the following: fasting or random blood sample on two separate occasions or a 75 g oral glucose tolerance test. People with impaired glucose tolerance or impaired fasting glycaemia should be retested afer 1 year. Children with suspected Type 1, with a single abnormal blood glucose reading should be admitted until the diagnosis is clarifed. Results from destruction most commonly autoimmune, Type 1 diabetes of the pancreatic beta cells. Characterized by insulin resistance and/or abnormal insulin secretion, either of which may predominate, Type 2 diabetes but both of which are usually present. Other specifc Tese are less common and include genetic disorders, types of infections, and diseases of the exocrine pancreas, Diabetes endocrinopathies or as a result of drugs. Public and professional awareness of the risk factors for and the symptoms of diabetes are an important step towards its control and prevention. It therefore has an impact by reducing both the need for diabetes care and the need to treat diabetes-related complications. While there is yet no conclusive evidence to suggest that type 1 diabetes can be prevented, primary prevention of type 2 diabetes is potentially possible. Lifestyle changes aimed at weight control and increased physical activity are important objectives in the prevention of type 2 diabetes. The components of lifestyle modifcation and their aims should include, but not be limited to , the following list: Weight loss of 5%-10%. Action taken early in the course of diabetes is more benefcial in terms of quality of life and is more cost-efective, especially if this action can prevent hospitalization. Tere is now conclusive evidence that good control of blood glucose levels can substantially reduce the risk of developing complications and slow their progression in all types of diabetes. The management of high blood pressure and raised blood lipids (fats) is equally important. Health workers need not only provide treatment and care for people with diabetes but also play a major role in active prevention of diabetes through health promotion and public health education. Tese components comprise the metabolic syndrome, a known cluster of risk factors for ischaemic heart disease, stroke and peripheral vascular disease. The pathogenesis of the syndrome is strongly linked to central obesity and tissue resistance to insulin action arising from genetic pre-disposition or acquired factors, such as obesity and physical inactivity 3. The frst line of treatment for all components is lifestyle change weight loss and increased physical activity. Insulin sensitivity can be improved by non-pharmacological and pharmacological means. Being overweight/obese signifcantly increases the risk of morbidity and mortality from Type 2 diabetes and its co-morbidities. All children and adolescents with type 1 diabetes should have access to the multi-disciplinary team at least once per year where complications screening are undertaken annually for pre-pubertal children afer fve years of diagnosis and in pubertal adolescents afer two years of diagnosis. Initial assessment The successful management of the diabetic patient depends on working in partnership with the patient and all members of the team responsible for the various elements of their care. Before a management plan can be agreed, an initial assessment of the health and lifestyle of the patient must be undertaken with particular reference to: History Diabetic history, both recent and historical Symptoms of potential complications. Ongoing education includes meal planning, management for life activities and growth and self management. Give advice and support on smoking cessation where appropriate Psychosocial support Diabetes in a child or adolescent may be associated with acute distress and in some cases prolonged distress for both the individual and the family. Pre-existing psychological, social, personal, family or environmental problems are likely to be exacerbated. Physical activity Regular physical activity is an essential component of a healthy lifestyle for all children and adolescents, including those with diabetes. Advise that regular physical activity can reduce arterial risk in the medium to long term and where appropriate discuss adjustments to insulin regime or calorie intake during exercise. Nutrition Nutrition education for children and adolescents is an ongoing process that needs to be provided at a time that is suitable to meet the individual needs of the families. In order to achieve optimal outcomes for the child/adolescent and family, initial and ongoing nutrition education should ideally be delivered by a dietitian-nutritionist who has appropriate training and experience in paediatric diabetes management. Insulin therapy and blood glucose monitoring Patients with type 1 diabetes should be started on insulin rather than oral glucose lowering agents. Review assessment All diabetics should be reviewed at least annually and more frequently if there are any factors which may cause concern to the patient or their doctor. The aim of regular review should be to assess and decrease the risk of known complications of diabetes such as peripheral vascular disease, nephropathy and retinopathy. A review appointment may involve many health care workers such as dietician, optometrist, podiatrist or other appropriately trained members of staf. Management of Type 2 Diabetes The successful establishment of the diabetes health-care team and infrastructure to support it is critical for the achievement of these management goals. This includes provision of education for health-care professionals and for people living with diabetes. Management of Type 2 diabetes entails the following components: Treatment of hyperglycaemia Treatment of hypertension and dyslipidaemias Prevention and treatment of microvascular complications Prevention and treatment of macrovascular complications 1. This is one of the cornerstones of management together with diet, physical activity and pharmacotherapy, and is critical in improving the outcome. People with diabetes and their families need to know: that diabetes is serious chronic disease, has no cure, but can be controlled that complications are not inevitable (they can be prevented) that the cornerstones of therapy include: education, what foods to eat, how much and how ofen to eat, how to exercise and its precautions, how and when to take medications their metabolic and blood pressure targets how to look afer their feet, and thus prevent ulcers and amputations how to avoid other long-term complications that regular medical check ups are essential when to seek medical help. Dietary modifcation and increasing level of physical activity should be the frst steps in the management of newly diagnosed people with Type 2 diabetes, and have to be maintained. Principles of dietary management of Type 2 diabetes mellitus All members of the diabetes-care team must have knowledge about nutrition to be able to educate people with diabetes about dietary measures. Both types of activity maybe prescribed to persons with Type 2 diabetes mellitus, but the aerobic form is usually preferred. In most parts of Kenya, prescribing formal exercise in gyms or requiring special equipment is a recipe for non-adherence. Terefore, patients should be encouraged to integrate increased physical activity into their daily routine. The programme should impose minimum, if any, extra fnancial outlay in new equipment and materials. General principles and recommendations for physical activity in Type 2 diabetes mellitus A detailed physical evaluation of cardiovascular, renal, eye and foot status (including neurological) should be performed before starting an exercise programme. The list is not exhaustive but includes agents that are most commonly used in Kenya. Stocking these agents would meet the diabetes-care needs of most diabetes facilities. In such patients, use short-acting sulphonylureas such as glimepiride, gliclazide. Step by step management of type 2 diabetes mellitus dose) Titrate dose of Metformin upwards and /or add Sulfonylurea: start with low dose: increase 3 monthly as needed Continue above, add bedtime intermediate acting insulin Tree-drug combination therapy can be used when two-drug regimens fail to achieve target values. This is split into 2/3 in the morning and 1/3 in the evening, at 30 minutes before the morning and the evening meals. If the requirement of insulin exceeds 30 units/day, referral should be considered. Examples of some of the types of insulins available locally in the market Insulin Examples available preparation in the market Rapid-acting Humalog or lispro, Rapid-acting insulin covers insulin analogues Novolog or aspart, needs for meals eaten at the same Apidra or glulisine time as the injection. Novolin 70/30 Premixed insulin)* Long acting Lantus/Glargine Long-acting insulin covers insulin analogue Levemir/Detemir needs for about 1 full day. This type Ultralente of insulin is ofen combined, when needed, with rapid or short-acting insulin. If a secondary cause is suspected, refer for comprehensive evaluation, Assessment should include staging and risk stratifcation. Look for other components of metabolic syndrome and complications of both diabetes and hypertension. If this fails to control the blood pressure, monotherapy should be commenced and if unsuccessful, combination therapy will be required to achieve the target blood pressure level. Two major processes lead to cardiovascular disease: atherosclerosis and hypertension. The clinical spectrum of cardiovascular disease is: a) Coronary heart disease: Angina (which may be silent).

However, vomiting may occur as fontanel, an altered level of consciousness, or neurologic fndings (3rd a response to severe non-intestinal pain such as in testicular torsion; or 6th cranial nerve palsies). Care should be taken to determine whether the pain occurs before or after the onset of the vomiting. If the vomiting occurred before the onset of pain, Recurrent Abdominal Pain by Age Group* the clinician should suspect gastroenteritis or another nonspecifc problem. Diarrhea may also occur in the presence of acute Cystic fbrosis Pancreatitis Gallbladder disease appendicitis or other pelvic infections (such as those resulting from Rotational defects Parasites Pelvic infammatory pelvic infammatory disease, tubo-ovarian abscess); in these cases, Malformations Tumors/masses disease diarrhea is caused by infammation and irritation of an area of colon Esophagitis Diskitis/osteomyelitis Ovarian cysts adjacent to an infammatory mass.

If the child does this easily, Pelvis Great vessels the probability of an acute intraabdominal infammatory process is Pelvic organs quite low. Outer bulky clothing should be removed to allow good Retroperitoneal space exposure of the abdomen without the child having to feel vulnerable. An accurate examination in a Secondary Site depends on the childs trust and cooperation. A conversation with the child about family, friends, pets, school, sports, music, or other specifc Cholecystitis radiates to subscapular area interests of that child diverts attention (distraction) from the examina Splenic injury radiates to shoulder tion and increases cooperation.

Tenesmus can be seen in the setting of proctocolitis or the diagnosis of acute appendicitis or other problems necessitating infammatory bowel disease and is often misinterpreted by the patient surgical intervention. The presence of headache, sore throat, and acidosis (shock, diabetes mellitus, or toxic ingestion), an intrapulmo other generalized aches and pains moves the examiner away from a nary process, sepsis, or fever. The vital signs must be viewed in context diagnosis of an acute problem warranting surgery and strongly sug but may be the frst clue to a serious illness. Asking the child to point to the area of Examination of the head, neck, chest, and extremities may precede worst pain sometimes results in the child pointing to the head or the abdominal examination. The examiner must be careful to remember the whole child and location of the pain, a careful examination of the ears is important, not to focus on the abdomen just because that is the area of the pre but can be performed at the end of the examination. Many systemic diseases directly or indirectly pharyngitis or mononucleosis is sometimes accompanied by severe produce abdominal pain and must be considered in the differential abdominal pain. Children with lower members, classmates, or playmates who have recently had similar lobe bacterial pneumonia present with severe abdominal pain, high symptoms.

A strong family history of migraine headaches in a child process, and examination of the lungs should demonstrate the with several previous episodes of intense abdominal pain that have pneumonia. The family must be asked about familial diseases and with the child as comfortable as possible. Previous intraabdominal actually touches the childs abdomen, he or she should observe it, operations may result in adhesions that can cause pain, intestinal looking for distention, inguinal masses, peristaltic waves, and scars obstruction, or both. A history of previous intraabdominal surgeries from old injuries or surgical incisions. Next, illnesses result in identifable or predictable causes of abdominal pain the child should be asked to indicate with one fnger the point of great (Table 10. The point may be a vague circle in the area of the umbilicus, but if the child specifes a defned spot, the examiner should avoid that Physical Examination area until the remainder of the abdomen has been palpated. The physical examination begins when the clinician enters the room Gentleness is essential to successful palpation of the abdomen. The and observes the childs activity and demeanor while obtaining the examiner must warm both hands and the stethoscope before touching history. The stethoscope is an excellent tool for palpation of the in discomfort, alert but lying very still, or bouncing all over the room Auscultation of the chest can simply be extended to the Each of these activities conveys a message. The listless, lethargic child abdomen, with the examiner assuring the child that the stethoscope may be in shock, dehydrated, and very ill. Bowel sounds are usually nonspecifc in most children with abdom Attention is paid during palpation to the presence of masses. High-pitched examiner should focus on fnding the location of pain and the presence tinkling sounds or rushes are usually associated with an obstructive or absence of guarding or rebound tenderness. Bowel sounds in gastroenteritis are ordinarily very active and voluntary or involuntary (often referred to as rigidity) contraction of loud but may be normal. Fear of pain, rather than actual pain elic sounds in the early stages, but bowel sounds disappear with diffuse ited by palpation, is the most common cause for voluntary guarding peritonitis. As the examiner continues to listen or board-like abdomen is the result of involuntary guarding and over the entire anterior abdomen, the pressure on the head of the cannot be overcome by distraction. Voluntary guarding usually starts stethoscope increases until the examiner is, in fact, palpating with the before the palpation starts and can be overcome by asking the child to stethoscope. This often is a much more reliable method of eliciting true take deep breaths, fexing the knees and hips, or by using other distrac tenderness and guarding than is the palpating hand. When encoun Palpation is begun as far away from the area of pain identifed by tering tenderness, the examiner should palpate only deeply enough to the child as possible. The examiners hand should be softly placed fat elicit the complaint of pain and some guarding. The clinician should watch the childs face, not the during examination of the anterior abdominal wall. Internal rotation is most likely to cause pain as a result of esophagitis, lymphoma pelvic or retroperitoneal disease or both. The test Mononucleosis Hepatitis, splenic rupture may be performed passively or actively. The hip is passively extended, Henoch-Schonlein purpura Mucosal hemorrhage, intussusception thus stretching the psoas muscle (solid arrow).

In: Practical Strategies in Upper respiratory tract Pneumonia, mesenteric adenitis Outpatient Medicine. Inborn errors of metabolism, Pancreatitisthe fanks and back must be inspected and palpated. Percussion at hypertriglyceridemia, the costovertebral angle elicits pain in the presence of renal or peri hypercalcemia nephric infammation. Vertebral body and disk disease may be detected Drugs (valproic acid) Pancreatitis by palpitation of the spine. In postpu bertal girls, a pelvic examination may be valuable, regardless of the infamed focus within the abdomen is compressed and the pressure is patients sexual activity history. If a diagnosis isthe standard method to elicit rebound is to palpate deeply, then sud already obvious, the rectal examination may be deferred. Although this sign aids in the deter study or colonoscopy is planned, a rectal examination may be unneces mination of the presence of an intraperitoneal infammatory process, it is sary. If constipation is suspected as the cause for pain, rectal examina not necessary to cause extra discomfort or stress, particularly in younger tion should be performed but should be the last part of the physical children; it is not recommended. The child should be detected by maneuvers such as asking the child to jump, cough, or relaxed and should be given an honest explanation of the procedure. The examiner should use plenty of lubricant and should perform the Other areas of infammation can be detected by maneuvers that rectal examination very gently. If the child strongly resists, it is point move muscles adjacent to the infammation. This is when the rectal exami occurs when pain is unchanged or increased when the supine patient nation may truly be deferred. Lateralizing pain, masses, and the tenses the abdominal wall by lifting the head and shoulders off the presence and character of stool in the rectum are assessed. Carnett sign is a sensitive tool to discriminate abdom should always be tested for blood except in children with gastrostomy inal wall pain from visceral pain. The psoas sign occurs when elevation or nasogastric tubes since it will invariably be positive and can be and extension of the leg against the pressure of the examiners hand misleading. An infammatory mass, such as an infamed appendix, a Clues to an organic and at times more serious cause of abdominal psoas abscess, or a perinephric abscess, in contact with the psoas pain are noted in Table 10. Likewise, the obturator sign is pain suggest a surgical abdomen, most often caused by peritonitis are with fexion of the thigh at right angles to the trunk and external rota noted in Table 10. In addition, the presence of shock suggests other tion of the same leg while the patient is in the supine position. However, a striking lymphocytosis may suggest (constipation, irritable bowel, dysmenorrhea, and lactase defciency). Overreliance on the complete blood count alone can cause delay in reaching the correct diagnosis. Urinalysis Laboratory Evaluationthe urinalysis is an important and useful laboratory test in the evalu After a careful history is obtained and thorough physical examination ation of abdominal pain. The presence of ketones and a high specifc is performed, the diagnosis or a short list of possible diagnoses should gravity suggest poor food intake and dehydration. Laboratory data are supportive in confrming or ruling glucose and ketones in the urine indicate diabetic ketoacidosis. The presence of both white cells and bacteria Complete Blood Cell Count indicates a urinary tract infection; either fnding alone may not bethe hemoglobin and hematocrit levels can reveal anemia caused by suffcient for that diagnosis. White blood cells may be present in the acute or chronic blood loss (as with ulcers, infammatory bowel disease, urine from irritation caused by an infammatory mass adjacent to the Meckel diverticula) or the anemia of chronic disease (as with systemic bladder or ureter; hematuria may be seen with nephrolithiasis. The white blood cell count indicates the possibility of infection or blood dyscrasias. In Other Laboratory Tests uncomplicated acute appendicitis, the white blood cell count ranges Other laboratory tests, such as measurement of serum electrolytes, from normal values to as high as 16,000. In studies of children with acute appendicitis, 95% had neutrophilia, but only half had Imaging Evaluation leukocytosis in the frst 24 hours. If the childs history and physical Multitudes of imaging studies are available; none should be obtained examination fndings are highly suggestive of appendicitis, a normal or until the patient has been examined. If the diagnosis is or without upright lateral views of the chest and abdomen, are rou already obvious, specifc therapy is indicated. In some situations, other tinely obtained in most emergency departments as part of the evalua types of imaging studies are more useful, and plain radiographs are tion of acute abdominal pain. However, early in the disease, the physical Ultrasonography examination may be more helpful. Lower-abdominal gynecologic positive when they are obtained as part of the routine work-up for pain in females, especially in adolescent females, can be confused with abdominal pain. Pelvic ultrasonography demonstrates pathologic pro illness, 46% of the results are positive. Plain abdominal radiographs cesses of the ovaries and fallopian tubes, the size of the uterus, and the may be helpful to confrm the presence of intestinal obstruction, pneu presence of free fuid in the pelvis. An enlarged, infamed appendix can matosis intestinalis, renal or biliary tract calculi, calcifed fecaliths, or also be visualized. These studies whom the diagnosis is not obvious should undergo an ultrasono detect bowel distention (air-fuid levels on upright views), calcifcation, graphic examination. If free air or intestinal obstruction is suspected, the abdominal bile duct can be visualized by ultrasonography; all 3 support the diag flms must include a fat and upright or decubitus view of the abdomen nosis of biliary disease. Ultrasonography also details the character In acute appendicitis, a calcifed appendicolith (appendiceal feca of abdominal masses, differentiating cystic from solid masses, and can lith) may be seen. This fnding automatically makes the be helpful in demonstrating free fuid or abscesses. The anatomy of the diagnosis of appendiceal dysfunction and confrms the need for urinary tract is well defned by ultrasonography; nephromegaly may appendectomy. More often, the noncalcifed appendicolith may is dependent on the expertise of the regional imaging center. If an ileus or intestinal obstruc tion is present, interpretation of the ultrasonographic examination becomes diffcult because of the multiple air-flled loops of intestine. Contrast Studies In some situations, certain bowel lesions are best delineated with a contrast medium placed in the bowel, either in an upper gastro intestinal series or by enema. If a colonic obstruction is suspected, such as in Hirschsprung disease, the appropriate contrast material is a barium enema. However, the sensitivity and specifcity of contrast enema for detection of Hirschsprung disease is approximately 70% and 83%, respectively. If the suspicion is high for the disease, the patient should be referred for further evaluation with either suction rectal biopsy or anorectal manometry. If the presence of gastrointestinal perforation is possible, regardless of the etiology, a water-soluble agent should be used instead of barium. Malrotation of the midgut with a volvulus in infants and older children is often seen on ultrasonography but can be diagnosed by an upper gastrointestinal study. In the infant who presents with an acute abdomen and bilious vomiting and in the older child who manifests chronic abdominal pain and intermittent vomiting, the oral barium contrast study is highly reliable to rule out causes of obstruction such as intestinal malrotation with midgut volvulus or other causes for anatomic obstruction (duodenal web, annular pancreas, superior mes enteric artery syndrome).
