Consolidation/ early intensification phase After complete remission if there is no further treatment given purchase unisom 25 mg, leukemia cells will expand and lead to relapse unisom 25 mg amex. Appropriate preventive measures should routinely be employed to prevent infections in such immunocompromised patients. These include Isolation of staff and visitors by the use of face masks Practice careful hand washing before coming in contact with the patient Advise the patient to eat only cooked foods When infections occur, gram negative sepsis is the commonest presentation, which requires prompt evaluation and empirical antibiotic treatment until definitive diagnosis is made by blood culture, after which the antibiotic(s) can be modified depending on the organism identified & its drug sensitivity. However, the majority will have signs and symptoms resulting from:- 1) tissue infiltration by leukemic cells 2) Bone marrow failure with peripheral blood cytopenias and immune suppression. If a patient has stage 0 disease without other poor prognostic factors, the median survival would be more than 10 yrs without treatment. It has a progressive clinical course with three phases starting with chronic phase and evolving to accelerated phase and then to blast transformation. Chronic Phase: The onset is insidious and some patients can be diagnosed while asymptomatic during health screening visits. Physical examination may show In the early stage 90% of or more of the cases may show o Moderately pale conjunctivae o Enlarged spleen and mild liver enlargement. Moreover immature granulocytes such as promyelocytes, myelocytes and metamyelocytes are seen in the peripheral film with increased number. Some myeloblasts are also seen, and the percentage of blasts varies according to the stage of the disease, i. Basopilia and monocytosis are commonly observed in the accelerated phase & blast transformation. Lymphomas Learning objectives: At the end of this lesson, the student will be able to:- 1. Principles of management of lymphomas Definition: Malignant transformation of cells residing predominantly in lymphoid tissue. Lymphoma is broadly classified as Hodgkins disease Non-Hodgkins lymphomas A. Hodgkins disease Epidemiology: It has bimodal age incidence (20-30 years and > 50 years). Fever is found in 30% of patients, and it described as Pel ebsteins fever characterized by weeks of febrile period, interspersed by several weeks of afebrile period. Moreover patients will have increased risk of reactivation of latent Tuberculosis infection. Lymphocytic depleted Clinical staging Stage 1: Only affecting one lymph node area 421 Internal Medicine Stage 2: 2 or more lymph node areas on the same side of the diaphragm involved Stage 3: Disease involving lymph nodes above and below diaphragm; splenic involvement is included here. Stage 4: Extra-nodal site involvement (Liver, bone marrow and other extra nodal sites) Depending on the presence or absence of constitutional symptoms the stages are further classified as A (no constitutional symptoms) and B (presence of constitutional symptoms. Relapse cases are better treated with autologous Bone marrow transplantation with total body irradiation and high dose chemotherapy. Disorders of Hemostasis Bleeding Disorders Learning objectives: at the end of this topic students are expected to:- 1. Know commoner causes of coagulation abnormalities with their peculiarity and similarity Abnormal bleeding may be due to:- 1. Primary haemostatic disorders : bleeding disorders resulting form either platlet or vascular abnormalities Vascular disorders Thrombocytopenia Functional platelet defect 2. Thrombocytopenia: May follow any of the following three mechanisms Decreased bone marrow production Increased splenic sequestration or Accelerated destruction of platelets To determine the etiology one should do Careful examination of peripheral morphology Assessment of marrow morphology by examination of an aspirate or biopsy An estimate of splenic size by bed side palpation supplemented by ultrasonography. Vascular bleeding disorders 1) Hereditary hemorrhagic telangiectasia : is an autosomal dominant disorder 2) Acquired vascular defects: Simple easy bruising: benign disorder seen in women of child bearing age. Is characterized by purpuric rash on the buttock and extensor surfaces; abdominal pain; painful joint swellings; hematuria. Introduction to Diseases of the Endocrine System Like the nervous and the immune systems the endocrine system main function is being a media of intercellular communication for a proper function of the body. Hormones are directly released into the blood therefore are said to be produced by ductless glands. Some hormones are bound to carrier proteins for transport but it is the free form that is physiologically active. High level of thyroid hormone results in hyperthyroidism while a low level of hormone results in hypothyroidism. Hormone levels are too low making routine laboratory determination difficult and as a result very sensitive assay are needed which are not routinely available due to expense and special expertise needed. Each of the major hypothalamic pituitary hormone axes is governed by a negative feedback, a process that maintains hormonal levels within a relatively normal range. The Hypothalamus The hypothalamus produces different releasing hormones that stimulate the pituitary gland. The pituitary gland produces trophic hormones that stimulate the peripheral endocrine glands. The peripheral glands produce specific hormones: The thyroid glands produce Thyroid hormone (T3 and T4 ) The adrenal glands produce Cortical Ovary and testes produce hormones that control sexual activity and reproduction. Other endocrine organs Pancreas: produces insulin and glucagon Liver: produces somatostatin Kidneys: produce : renin, angiotensin, erythropoietin, Vit-D Stomach: produce gastrin The target cells execute the command delivered by hormones.
Can be used prior to surgery/radiotherapy to control micro-metastases/improve operability buy unisom 25 mg free shipping, or palliatively order 25mg unisom with visa. Cisplatin and Etoposide are the gold standards amongst the older agents Small Cell: 70 80% have metastasised at diagnosis Very rapid doubling time No place for surgery Mainly managed with chemo +/- radiotherapy (makes a dismal outlook a bit better) Sleep Apnoea See also: Treatment of Insomnia, page 534 for Treatment of Insomnia See also Tiredness, page 6 Sleepiness Varies according to circadian cycle: two sleep gates each day, 2 3 pm and 10 11 pm (correlates with melatoin) Obstructive sleep apnoea is the most common cause of excessive sleepiness. Variety of causes including neuromuscular and chest wall deformities Cheyne-Stokes Respiration: usually with advanced heart failure. Treatment: codeine or anti-Parkinson drugs Narcolepsy: Normal sleep at night and frequently going to sleep during the day. Can also be complicated by cataplexy (sudden loss of muscle tone in response to emotional stimuli). Need to titrate pressure Treat allergic rhinitis Medication: Sleeping pills make it worse stop them Dental devices Surgery: Kids tonsils and adenoids. Prone to infection so steroids worsen the condition by depressing the immune system. Bronchial lavage effective in acute episodes A number of vasculitis affect the lung. Usually found as incidental findings on X-ray Primary Pulmonary Hypertension: rare, usually in young women. A large histiocyte with one bland folded nucleus, abundant eosinophilic cytoplasm with indistinct cell borders. X-rays show multiple nodules scattered through both lungs Langhans giant cell: (not the same as Langerhans cell) multinucleated giant cell in granulomas, with nuclei arranged around the periphery of the cell in a horseshoe pattern Sequestration: Extralobular: Congenital. Mass of lung tissue not connected to bronchial tree and outside the visceral pleura Intralobar sequestration: usually acquired. Within the visceral pleura but not connected to the bronchial tree Differential of Solitary lung nodule: Tumour: benign (bronchial adenoma or pulmonary hamartoma) or malignant Tb Sarcoidosis Other granuloma: eg fungal Haematoma (ie blood clot, eg in cavity following lung contusion) th th 92 4 and 5 Year Notes Endocrine and Electrolytes History. Ketoacidosis will develop unless insulin given (if any endogenous insulin then no ketones) Incidence up to 20 yrs: 10 15/100,000 Prevalence: 0. So when start insulin replacement back titrate (after stabilised) type 1 may have honeymoon period until no endogenous insulin Currently being investigated for prevention in high risk individuals (ie have antibodies but not frank disease): Cows milk avoidance until 6 months of age Early oral insulin therapy autoimmune modulation Nicotinamide (vitamin B) supplementation Treatment goals: stable blood sugar, prevent/monitor complications, promote normal growth and development, maintenance of normal weight Investigations for both Type 1 and Type 2 Diabetes Glucose testing HbA1C. Dipsticks detect > 150 g/l (ie insensitive) Microalbuminuria hard to test (needs 24 hr urine). After 30 years 80% have background retinopathy and 7 8% are blind (see Focal Ischaemic Retinal Disease, page 145). Use normal saline, and reduce to hypotonic fluid once rehydrated and glucose < 15 mmol/l or if Na > 150 mmol/l Potassium 20 mmol in first 6 hours then 10 mmol/hr according to plasma levels. If plasma K high then delay adding K until this has normalised Insulin: actrapid 10 20 units. Involves significant education For Impaired Glucose tolerance and Impaired fasting glucose: lifestyle change and monitoring Diet: Saturated fats, low glycaemic index foods (sugar presented slower to liver, able to convert more to glycogen). Intensive therapy reduced risk in all categories, but hypoglycaemia and some weight gain Biguanides: eg metformin. Not in hypoxic lung disease or cardiac disease Sulphonylureas: insulin release from -islet cells (must have some left for it to work), gluconeogenesis and glycogenolysis. Only measure T3 in hyperthyroid (as it drives symptoms) Bound in plasma to thyroid binding globulin Intercurrent illness: fT4 rises (liver stops converting T4 to T3 straight away want to be catabolic) then T4 falls to subnormal levels as thyroid production slows. Does not parallel degree of toxicosis At presentation, patient may be euthyroid, hypothyroid or hyperthyroid Management: Early referral. Follicles same as in follicular carcinoma but carcinoma shows invasion of blood vessels Toxic adenoma (= Plummers Disease, Thyroid autonomy): a nodule producing T3 or T4 hot spot on scan Subacute Thyroiditis: = De Quervains Disease. If rapidly destructive then acute thyroiditis = Inflammation of the thyroid secondary to: Pregnancy: autoimmune. Usually self-limiting If severe, then 3 phases: Prodromal: may be 4 6 weeks longs Hyperthyroid: Release of preformed T3 and T4. Steroids work but prolong illness th th 98 4 and 5 Year Notes Histology: Neutrophils attack cuboidal epithelium (acute inflammation) Thyroglobulin leaks out granuloma formation Resolution Post-partum thyroiditis: hyper or hypo thyroid. Risk of agranulocytosis with Carbimazole and propylthiouracil Toxic multi-nodular goitre and toxic adenoma unlikely to remit following drugs Partial thyroidectomy: risk to recurrent laryngeal and parathyroids. Have oncocytes (cells with mitochondria) Spontaneous primary atrophic hypothyroidism. F:M = 6: 1 Woody Thyroiditis (Riedels Thyroiditis): fibrous replacement of the thyroid Iatrogenic: Following thyroidectomy and radio-iodine treatment Drug induced: eg amiodarone ( hypo or hyper), lithium, iodine in expectorants Not deep x-ray treatment to face and neck (does lead to nodular goitre), Juvenile: Dyshormonogenesis: eg partial deficiency of peroxidase gland hyperplasia restore deficiency. T = 7 days so adjusting dose takes long time Note: hypothyroid slow drug metabolism If pre-existing heart disease, introduce very slowly. False positives with depression, obesity and drugs affecting metabolism of dexamethasone (eg phenytoin, phenobarbitone) Midnight cortisol nearly as good: but must do as an inpatient (need to wake to do it and be unstressed) midnight is low point of diurnal cycle, if high then diurnal cycle depressed Do high dose dexamethasone test (8mg) to determine type of Cushings or if obese Causes and treatment: Exogenous corticosteroid administration: reduce as much as possible.

A Report by the Expert Commission on Addressing the Contribution of Livestock to the Antibiotic Resistance Crisis The Expert Commission on Addressing the Contribution of Livestock to the Antibiotic Resistance Crisis is comprised of the following members: Lance B buy unisom 25 mg cheap. Enhancing Surveillance and Data Integration to Inform Antibiotic Use Policy 30 Conclusion 37 Endnotes 39 Appendix A 50 Appendix B 53 Appendix C 57 Appendix D 59 Appendix E 61 Throughout this document unisom 25mg sale, we use antibiotics as opposed to antimicrobials. However, the plan to curtail antibiotic use in food Before the discovery of antibiotics, patients with animal production is narrower in scope, mainly routine bacterial infections often died. Without addressing the limited phase-out of antibiotics urgent action, that reality is likely to return as in animal feed or water for growth promotion infections that are no longer treatable with todays purposes. Congress granting fnancial rewards to accounting for roughly 13% of the worlds total. Until we become better stewards of antibiotics, both in human medicine and in livestock production, these life-saving drugs will continue to become less effective, and the effectiveness of any antibiotics developed in the future will be at constant risk. Reduce the need for antibiotics by adopting non-antibiotic best practices, and by innovating new technologies, to maintain animal health and prevent disease. Antibiotics in the Critically important category are only used to treat animals sick with a specifc bacterial disease. Develop a system for collecting detailed, comprehensive data on actual antibiotic use, and collect essential data. Coordinate with and learn from the other countries in developing a comprehensive data collection system. Adopt a metric for reporting data on antibiotic sales or use that better allows trends to be identifed, explained and compared. Expand surveillance for emerging resistance using next generation sequencing technology. Pilot test approaches that comprehensively detect resistance in all bacteria in a sample. Many of the recommendations draw upon successful models already implemented in Denmark and the Netherlands, two European countries with robust livestock sectors, comparable in size to that found in some of the most important livestock-producing states in the U. Antibiotic use in food animal production in both countries has been markedly reduced, and has been generally accompanied by lowered or plateaued levels 24 25 26 of resistant bacteria on animals and in meat, and sometimes in human populations. Beyond its human costs, the antibiotic resistance epidemic poses an emerging threat to national and economic security. Raising poultry, pigs and cattle successfully also depends on having antibiotics that work on sick animals. But this reliance on what are now the cornerstones of modern medicine could be in jeopardy. Without stronger action today, physicians and veterinarians face a future with less effective antibiotics, where their treatment of patients and animals may need to be substantially reconsidered. Agriculture A One Health Perspective Antibiotics are often necessary to treat sick patients and animals. But all uses of antibiotics even the Experts agree that the 21st century crisis of most prudent can contribute to resistance. Underscoring the avoid using antibiotics completely but rather to use importance of a One Health approach is the fact them appropriately and only when necessary as that scientists estimate 6 out of every 10 infectious the discoverer of the frst antibiotic (penicillin), Sir diseases in people are spread from animals49, as Alexander Fleming, acknowledged more than seven well as a recent study suggesting that at least some decades ago. This Commission be the highest priority for human medicine, such has taken a One Health approach as refected as macrolides, fuoroquinolones and 3rd generation by its make-up, as well as in its conclusions and cephalosporins. Yet, as we discuss further, settings, is largely a numbers game the higher the the U. Box A: One Health: Factors That Can Contribute to the Spread of Antibiotic Resistance The greater the quantity of antibiotics used, the more resistance will emerge and spread. However, comprehensive goals and milestones to better track, understand and reduce antibiotic use in human settings are not mirrored by similarly comprehensive goals around antibiotic use in the production of livestock and poultry. To address these shortcomings, the Roadmap makes policy recommendations in three key areas: decreasing antibiotic use, monitoring antibiotic use, and surveilling antibiotic resistance. These recommendations are largely aimed at both federal and state policymakers, but also go beyond government policy. For example, Appendix A offers tools that medical professionals can use to help address livestock overuse of antibiotics and Appendix C includes recommendations for universities, hospitals, and other buyers of meat and poultry to use in procuring products. Decreasing Livestock Use of Medically Important Antibiotics It is the Commissions shared sense that the statements in Box A (page 7) capture important connections between antibiotic use and antibiotic resistance. They lead in turn to the following general priorities for policy action, which are applicable not only to the U. Priority #1: Ensure antibiotics are used only when necessary and effective, and when non-antibiotic alternatives are unavailable, so as to reduce overall exposure of bacteria to antibiotics (see Box B), and therefore the emergence and spread of resistance. A) When directed by a veterinarian, antibiotics should be used to treat sick food-producing animals or those that have been exposed to an animal with diagnosed disease. Priority #2: Reduce the sale and use of medically important antibiotics, putting the highest priority on those deemed of greatest importance to human medicine. Priority #3: Administer antibiotics for the shortest time period (duration) necessary.
