The most common form of diabetic neuropathy is distal symmetric polyneuropathy often described as having a glove and stocking distribution buy discount super levitra 80 mg line. Diabetic polyradiculopathy is a syndrome characterized by severe disabling pain in the distribution of one or more nerve roots order 80mg super levitra otc. Peripheral mononeuropathies or simultaneous involvement of more than one nerve (mononeuropathy multiplex) may also occur 80mg super levitra visa. Autonomic Neuropathy in diabetes can involve multiple systems buy super levitra 80 mg on-line, including: the cardiovascular cheap super levitra 80 mg with amex, gastrointestinal, genitourinary, sudomotor, and metabolic systems. Autonomic neuropathies affecting the cardiovascular system cause a resting 32 tachycardia and orthostatic hypotension. Hyperhidrosis of the upper extremities and anhidrosis of the lower extremities result from sympathetic nervous system dysfunction. Anhidrosis of the feet can promote dry skin with cracking, which increases the risk of skin ulceration. Autonomic neuropathy may reduce counterregulatory hormone release, leading to an inability to sense hypoglycemia appropriately (hypoglycemia unawareness, thereby subjecting the patient to the risk of severe hypoglycemia and complicating efforts to improve glycemic control. One should consider other possible causes of neuropathy before ascribing signs and symptoms to be due to diabetic neuropathy as other causes of neuropathy may present in a similar manner. Diabetic foot disease Different types of diabetic tissue damage interact and combine in the feet, giving a wide variety of lesions ranging from relatively harmless dysaesthesiae to fulminating infections and widespread ulceration and gangrene. Factors that play important roles in the pathogenesis of diabetic foot ulcers include, • Neuropathy o Predisposes patient to repetitive trauma to the feet • Reduction in blood flow o Delays wound healing o Serves as a good medium for bacterial multiplication • Deformity in the feet o This leads to abnormal foot mechanics with misdistribution of pressure over parts of the feet. If the diabetic cannot see his feet properly, someone else must look at them at least weekly or, if there is marked loss of pinprick sensation, thrice weekly. The principles of treatment of diabetic foot ulcers involve the elimination of infection by draining pus or removing infected bone, by removing dead tissue likely to provide a focus for infection, and by using antibiotics if necessary. Healing is speeded by encouraging the greatest possible blood flow, and protecting the foot from trauma. Amputation may be required in case of life threatening infections by gas forming organisms or in cases where there is of dead tissue. Antibiotics choice should be guided by culture of either the local lesion or blood when infection is widespread. The control of glucose levels should be as strict as possible, as hyperglycemia is bound to bring about dysfunction of the leucocytes. These include • Abnormalities in plasma lipids • Increased liability to hypertension in diabetics • Structural narrowing of the lumina of vessels • The presence of a state that favors coagulation Patients may present with either clinical features of ischeamic heart disease or congestive heart failure in the absence of ischeamia (diabetic cardiomyopathy). Heart disease is the major cause of death among both type 1 and type 2 diabetics, and ultimately is likely to affect about 60 per cent of patients. The management of ischaemic heart disease among diabetics differs little from that generally employed. It is common in people older than 40yrs and results from variable combinations of insulin resistance and defects in insulin secretion. In the hypothetical case already mentioned the health officer requested the following laboratory investigations with the results shown below. Clinical features The presentation of patients depends on the type of diabetes and the stage of pathologic process. The disease is often present for many years before the diagnosis and chronic hyperglycemia may be responsible for susceptibility to infections (eg. Short term – immediate treatment to relieve the symptoms such as polydipsia, polyuria, or acute infection. Long term – to prevent the development or delay progression of complications of diabetes The treatment of diabetes can be categorized as non-drug therapy and drug therapy. Regular Physical exercise This results in improvements in the sense of well being, cardiovascular fitness, blood pressure, insulin sensitivity, weight reduction and glycemic control. Dietary Control A general dietary recommendation includes consumption of a balanced health diet composed of: - 10 – 20% protein - 30% fat - 50-60% carbohydrate Patients should be advised to avoid dimple sugars like table sugar, honey etc and low saturated fat and cholesterol white high fiber diet is recommended. Insulin is also used in type 2 diabetics when a combination of oral agents fails to achieve glucose targets and temporarily in patients with serious infection or surgery.

The network has completed nine rounds of proficiency testing since 1994 80 mg super levitra overnight delivery; cumulative results over the nine rounds generally indicate overall high performance of the network 80 mg super levitra sale. Following an evaluation by the supranational laboratory generic super levitra 80 mg free shipping, a decision is made on whether to carry out the survey or repeat proficiency testing generic 80 mg super levitra otc. The network has recently agreed such criteria and details will be published in the coming year discount 80mg super levitra fast delivery. Preliminary research has shown that at least one of the apparently borderline isolates was in fact a mixed culture containing one drug-resistant and one susceptible isolate; however, further exploration is warranted. There is a need for these costs to be met internationally to stabilize and enhance the network. The Laboratory Strengthening Subgroup seeks to assess and develop plans for improvement of entire national laboratory networks, with an emphasis on sputum smear microscopy. Improved laboratory networks will translate into improved diagnostic and treatment capacity, and more accurate surveillance of drug resistance. This is not always true of the data from individual sites, where the number of cultures examined is less than 1000, given that some drug resistance types show prevalences of 0. The total number of isolates examined is sufficiently high to guarantee statistical significance of both new cases and previously treated cases, even though all settings within some regions such as the Eastern Mediterranean and South-East Asia are not necessarily representative of the regions as a whole. The consistency of the findings argues for the robustness of the following conclusions. In patients with drug-resistant tuberculosis, additional drug resistance may develop if a prescribed multidrug regimen includes the drugs these patients are already resistant to. In this situation, some of these patients may end up effectively receiving monotherapy. In this respect the findings of worldwide drug resistance surveys are revealing, in that the prevalence of drug resistance is significantly higher among previously treated patients than among new patients in all regions. The only logical inference is that present treatment practices create significant numbers of new resistant cases and amplify already present resistance. This analysis shows a remarkable consistency, both globally and regionally, in the distribution of the major drug resistance types, as well as in the increase in drug resistance prevalence among previously treated cases relative to new cases. It should be noted that prevalence of drug resistance observed in previously treated cases is higher than in new cases in all regions. Since this difference is in great part directly related to the quality of drug treatment, this apparent characteristic could well lead to the development of an indicator that would measure the quality of treatment practices. The addition of a new drug to a failing drug regimen is an effective way of amplifying the drug resistance problem. Monoresistance can only be selected in the presence of a drug concentration leading to the selection of pre-existing mutant bacilli, whereas resistance to two drugs cannot be created simultaneously in the presence of effective concentrations of two drugs. This is because the number of bacilli present in the lesions (108) is usually much lower than the theoretically required bacillary load needed to produce double resistance, i. Results obtained in this study show that the proportions of monoresistance are lower in patients having re-treatment, whereas double resistance remains essentially unchanged. Triple and quadruple resistance are higher by about the same proportion as monoresistance is lower. Amplification caused by re-treatment is the easiest way to interpret these changes, i. The absence of a significant change in double resistance proportions can be explained by selective pressure, leading to an increase in triple and quadruple drug resistance modes thus balancing the inflow from the monoresistance mode. Since resistance in re-treatment cases mostly reflects the quality of recent treatment, these results could lead to the development of an indicator, based on the extent of amplification. The difference between previously treated and new case triple and quadruple resistance proportions could constitute such an indicator. Other pathways can and do exist but their contribution to the drug resistance problem is relatively minor. We can therefore state that monoresistance to H or to S is the foundation for the acquisition of additional drug resistance. Implications The above analysis has shown that there is circumstantial but compelling evidence that either monotherapy or “effective” monotherapy, or both, are more widespread than commonly thought.

Etiology • Staphylococcus aureus is the agent in 80% of cases • Gram negative rods and Staphylococcus in neonates • H super levitra 80 mg with mastercard. Influenza is seen in children under 5 years of age • History of trauma is common and may predispose children to osteomyelitis Pathology Bacteria reach the bone mostly via the hematogenous route trusted 80 mg super levitra. Infection begins in the metaphysis of a long bone and spreads through the cortex and medullary cavity causing thrombosis to vessels and bone infarction cheap super levitra 80mg with amex. Cloxacillin + Gentamycine - Children under 5 years:- Penicillinase resistant penicillins + Anti H purchase 80mg super levitra visa. Cloxacillin + Chloramphenicol - Patients above 5 years:- Penicllinase resistant penicillin E buy super levitra 80 mg amex. Pathology: The dead bone (sequester) lies in an abscess cavity surrounded by a newly formed bone (Involcrum) under the elevated periosteum. There may be skin hyper pigmentation around the sinus and palpable bone thickening. Treatment Antibiotics: Used for acute exacerbation and perioperate for about six weeks. Surgery: Surgery is done to remove a dead bone (sequesterectomy) or to eliminate an abscess cavity (saucerization). Conservative treatment is considered in a patient with minimal discharge and no obvious sequestrum or bone cavity. Amputation may be considered for extensive bone involvement and heavy discharge or frequent flare-ups which incapacitate the patient. Etiology: It varies in different age groups and is similar to that of acute osteomyelitis. Bacteria may reach the joint via the blood, local extension of osteomyelitis or directly in penetrating wounds of the joint. The pus formed in the joint is chondrolytic and destroys the joint cartilage if not evacuated. Diagnosis: History: The usual presenting symptoms are joint pain, swelling and fever. Immobilize the affected joint in functional position until inflammation subsides and physiotherapy to prevent joint stiffness. The intervertebral discs, the hip and knee joints are the most frequently affected. X-ray: - Joint space narrowing - Sub chondral bone destruction - Periarticular osteoporosis Open biopsy of the joint is done if diagnosis is still in doubt. Mechanism of injury 1- Tubular bone: - Direct violence to the bone - Indirectly due to twisting or angulation 97 2- Cancellous bone: - may be fractured by compression E. Transverse fracture of the patella Bone Healing o Progresses through the phase of hematoma, cellular proliferation, callus formation and remodeling o Generally takes longer than soft tissue healing o In general, a long bone takes 6-12 weeks to heal in an adult and 3-6 weeks in children. Associated life threatening injuries may be missed if evaluation of the patient is not systematic. B) Local treatment of the fracture:- I-Reduction • Means bringing the fractured bone to normal or near normal anatomic position. This is needed only for displaced fractures • Age and function of the patient are important in considering the goals of reduction • Reduction may be done in various ways: 1- Using gravity E. Femoral shaft fracture 3- Open (Operative) reduction: Used when other methods are not possible, have failed or a perfect anatomic reduction is needed. U-slab for humeral shaft fracture B) Skin traction: A method of applying traction using bandage, usually used in children and temporarily in adults. C) Skeletal traction: Traction applied via a pin inserted into the bone distal to the fracture. Tibial pin traction for femoral fracture 3- External fixation - This is a method of fixing the fracture by metal pins passed through the bone above and below the fracture and connected to a metal frame. B: Never close a compound fracture immediately in an attempt to convert it to a closed one. A subluxation is partial joint disruption with partial remaining but abnormal contact of articular surfaces. Types of Dislocation 1- Traumatic dislocations - This is a type of dislocation caused by trauma. A force strong enough to disrupt the joint capsule and other supporting ligamentous structures dislocates a previously normal joint. Septic hip dislocation 3- Recurrent dislocation - This is a dislocation which repeatedly occurs after trivial injuries due to weakening of the supportive joint structures 4- Congenital dislocation - A type of dislocation which is present congenitally since birth.

The endothelium lining the local blood vessel becomes “leaky” under the influence of histamine and other inflammatory mediators allowing neutrophils 80mg super levitra with amex, macrophages buy cheap super levitra 80 mg line, and fluid to move from the blood into the interstitial tissue spaces buy cheap super levitra 80mg on line. Antihistamines decrease allergies by blocking histamine receptors and as a result the histamine response cheap super levitra 80 mg on line. After containment of an injury order 80mg super levitra with mastercard, the tissue repair phase starts with removal of toxins and waste products. Clotting (coagulation) reduces blood loss from damaged blood vessels and forms a network of fibrin proteins that trap blood cells and bind the edges of the wound together. As healing progresses, fibroblasts from the surrounding connective tissues replace the collagen and extracellular material lost by the injury. Angiogenesis, the growth of new blood vessels, results in vascularization of the new tissue known as granulation tissue. The clot retracts pulling the edges of the wound together, and it slowly dissolves as the tissue is repaired. When a large amount of granulation tissue forms and capillaries disappear, a pale scar is often visible in the healed area. The process called secondary union occurs as the edges of the wound are pulled together by what is called wound contraction. When a wound is more than one quarter of an inch deep, sutures (stitches) are recommended to promote a primary union and avoid the formation of a disfiguring scar. All the cells, tissues, and organs are affected by senescence, with noticeable variability between individuals owing to different genetic makeup and lifestyles. The skin and other tissues become thinner and drier, reducing their elasticity, contributing to wrinkles and high blood pressure. Hair turns gray because follicles produce less melanin, the brown pigment of hair and the iris of the eye. The face looks flabby because elastic and collagen fibers decrease in connective tissue and muscle tone is lost. Glasses and hearing aids may become parts of life as the senses slowly deteriorate, all due to reduced elasticity. With age, fluid decreases in the fibrous cartilage disks intercalated between the vertebrae in the spine. More severe problems are not necessarily associated with the aging process and may be symptoms of underlying illness. The incidence of heart diseases, respiratory syndromes, and type 2 diabetes increases with age, though these are not necessarily age-dependent effects. Wound healing is slower in the elderly, accompanied by a higher frequency of infection as the capacity of the immune system to fend off pathogen declines. As they do, cells are less able to divide and 166 Chapter 4 | The Tissue Level of Organization regenerate. Because of alterations in cell membranes, transport of oxygen and nutrients into the cell and removal of carbon dioxide and waste products from the cell are not as efficient in the elderly. Cells may begin to function abnormally, which may lead to diseases associated with aging, including arthritis, memory issues, and some cancers. The progressive impact of aging on the body varies considerably among individuals, but Studies indicate, however, that exercise and healthy lifestyle choices can slow down the deterioration of the body that comes with old age. Uncontrolled growth, invasion into adjacent tissues, and colonization of other organs, if not treated early enough, are its hallmarks. However, if the modification affects key proteins that have an impact on the cell’s ability to proliferate in an orderly fashion, the cell starts to divide abnormally. A tumor becomes malignant, or cancerous, when it breaches the confines of its tissue, promotes angiogenesis, attracts the growth of capillaries, and metastasizes to other organs (Figure 4. Some cells, called cancer stem cells, appear to be a subtype of cell responsible for uncontrolled growth. Recent research shows that contrary to what was previously assumed, tumors are not disorganized masses of cells, but have their own structures. Traditional approaches, including surgery, radiation, chemotherapy, and hormonal therapy, aim to remove or kill rapidly dividing cancer cells, but these strategies have their limitations. To address this, researchers are working on pharmaceuticals that can target specific proteins implicated in cancer-associated molecular pathways. Connective tissue integrates the various parts of the body and provides support and protection to organs. All cells and tissues in the body derive from three germ layers in the embryo: the ectoderm, mesoderm, and endoderm. Different types of tissues form membranes that enclose organs, provide a friction-free interaction between organs, and keep organs together.
