Common causes include : Acute shigellosis Feaco-orally transmitted asthmatic bronchitis 20 order 100mcg proventil visa, as few as 10 - 100 bacteria are enough to cause diarrhea Initially multiplies in the small intestine causing secretary diarrhea asthma zyrtec order 100mcg proventil. Acute Salmonellosis Transmitted by ingestion of contaminated meat asthma definition xenophobia cheap proventil 100 mcg visa, dairy or poultry products. This is in marked contrast to the 3 - 4 wks febrile illness caused by Salmonella typhi and paratyphi, which are not usually associated with diarrhea. Campylobacter jejuni It may be responsible for up to 10% of acute diarrhea world wide. Norwalk and Rota viruses Invade and damage villous epithelial cells Cause diarrhea by interfering with absorption through selective destruction of absorptive villous tip cells with sparing of secretary crypt cells. Cysts or trophozoites can be identified in the stool, and treatment should be given in both cases. They may cause voluminous life threatening diarrheal diseases in patients with acquired immunodeficiency syndrome. Evaluation of a patient with diarrhea Careful interview of patients with diarrhea contributes in etiologic diagnosis, evaluation of severity of illness, and in designing treatment and preventive measures. Thus, the history should include Duration of illness: if the diarrhea lasts for 2 - 4 wks, acute diarrheal diseases are said to exist. However, if it lasts for more than 4 wks, consider chronic diarrheal diseases and infectious causes are unlikely. Bloody diarrhea is usually inflammatory or ischemic in origin and caused by invasive organisms, ulcerative colitis, or neoplasms Volume of diarrhea Large volume diarrhea indicates small bowel or proximal colonic diseases Scanty, frequent stools associated with urgency suggest left colon or rectal diseases Any association with specific meal? If diarrhea is associated with intake of Fat it is due to fatty intolerance Sweet diet it is due to osmotic diarrhea Milk and milk products - it is due to lactase deficiency Is there history of drug intake? Laxatives Chemotherapeutic agents 7) Presence of underlying diseases (like diabetes mellitus) or systemic symptoms Physical examination: Assess severity of dehydration, Wight loss and other associated signs in patient with chronic diarrhea. Diagnosis: Laboratory tests: 1) Culture and sensitivity testing to detect a pathogenic bacterial strains. Proctosigmoidoscopy: to exclude of confirm the diagnosis of inflammatory bowel diseases. Rehydration In patients with massive diarrhea and vomiting with hypotension intravenous fluids like Ringers lactate or Normal saline should be given in adequate amount. Antimicrobial therapy Antibiotics: Most acute infectious diarrheal diseases do not require antibiotic therapy because majority of them are self limited and viral in nature. In immunocompromized patients continue maintenance dose of the same drug three times a week. Anemia Learning objectives: At the end of this topic the student we be able to:- 1. Evaluate cases of anemia with appropriate history, physical examination and proper laboratory studies 4. Anemia: General approach a) Definition Functional definition: A significant reduction in red cell mass and a corresponding decrease in the 02 carrying capacity of the blood. For instance; 389 Internal Medicine Hgb or Hematocrite could be falsely elevated ( plasma volume) e. Clinical approach to the Patients with anemia Anemia is a manifestation of an underlying pathological condition.

There was uncertainty about the models ability to promote global access to antibiotics asthmatic bronchitis cure proventil 100mcg otc, and about whether the model could be implemented in low- and middle-income countries asthma treatment in pregnancy cheap generic proventil canada. Diagnosis confirmation model The diagnosis confirmation model is a diagnosis-driven asthma symptoms 2 year old buy 100mcg proventil fast delivery, dual-pricing model where a premium price is charged if the antibiotic is used for the entire course (based on a confirmed diagnosis or clinical decision) or a lesser price if the antibiotic is used first empirically and then promptly de-escalated after the receipt of the diagnostic/laboratory results. Some commented that since this model could be implemented today, it was unclear how this would improve antibacterial R&D incentives. The model was judged as financially feasible, implementable nationally, and compatible with national regulatory and reimbursement systems. In the discussion, stakeholders questioned if dual pricing was actually necessary. Some commented that hospitals must implement strict controls for budgetary reasons when using any extremely highly-priced products. These controls may be as effective for sustainable use as the dual-pricing mechanism. Some participants stated that diagnostic results were not always clear and that physicians might continue to administer the antibacterial therapy as long as the patient was improving. There was a general concern that the model promoted empiric use of a novel antibiotic. Discussion Throughout our assessments we have been clear that there is a need for different incentive models depending on the type of infection and patient population. The models need to ensure that risk and royalties are shared between stakeholders. Grants and market entry rewards (both partially and fully delinked models) received strong support and clearly needed further development and assessment. The non-profit antibiotic developer was transformed, based upon the feedback, into the pipeline coordinator, with more emphasis on collaboration with the private sector. The insurance licence model was shifted from an innovation to an access incentive, entitled the long-term supply continuity model, to be used to maintain reliable access to important but rarely used generic antibiotics. The diagnosis confirmation model was excluded because of its inability to be paired with any equitable availability models and because market entry rewards were deemed a stronger incentive. There is no one size fits all solution to incentivizing antibiotic innovation in a global market with a huge variety of unmet needs, healthcare systems and access requirements. A menu of incentives is required that can be adapted to the local context and yet still achieve the same goal of stimulating antibacterial innovation. The fund governments would be willing to do so on a runs parallel to the long-term basis, not only because of the traditional large sums involved but also given that the reimbursement system. If payout is based upon a ranking of global a company voluntarily health impact and theoretically could result opts into payments from in large payments to patented antibiotics the fund, it agrees to sell that offer little public health benefit. It then receives would be likely to deter private-sector an annual payment based investment.

Steroid injection if severe Plantar Fasciitis: Insertion of the tendon into the calcaneum Pain on standing and walking Is isolated, or with sero-negative arthritis Treatment: heel pads, reduced walking, steroid injection Chronic Compartment Syndrome Caused by tissue pressure in a closed fascial space circulation to muscles and nerves Presentation: pain or deep ache over compartment. Place forearm against shoulder and fingers on forehead to stop them tensing when you push on the spine. If you need to measure, then measure from the sternal notch to the chin in each position If neck pain, check neurology in arms Thoracolumbar Spine and Sacroiliac Joints Look for deformity inspect from both back and sides. Facet joint dislocation only occurs in association with severe damage to vertebrae Soft tissue: disruption of shadows Non-traumatic injuries very rarely have positive findings on plain X-ray Neck and Radiating Arm Pain Cervical Spondylosis Spondylosis is the most common disorder of the cervical spine. Tenderness occurs in the posterior neck muscles and scapular region, all movements are limited and painful Differential Diagnosis: Thoracic Outlet Syndrome: pain in the ulnar forearms and hand Carpal Tunnel Syndrome: pain and paraesthesia are worse at night. Nerve conduction is slowed across the wrist Rotator cuff lesions: pain is like one of a prolapsed cervical disc, but shoulder movements are abnormal and there are no neurological signs th th 238 4 and 5 Year Notes Cervical tumours: Symptoms are not intermittent and x-ray may be abnormal X-ray: Cervical disc spaces are narrowed. Oblique views may show encroachment of the intervertebral foramina Treatment: Heat and massage are soothing Neck collar is the most effective treatment during painful attacks Physiotherapy Operation is seldom indicated but if necessary then anterior fusion is appropriate Prolapsed Cervical Disc May be precipitated by local strain or injury, esp. Often unaffected by position of spine Pain of spinal origin: Upper lumbar refers to groin or anterior thighs. Lower lumbar refers to buttocks, posterior thighs or calves/feet Radicular back pain: sharp and radiates from spine to leg in territory of nerve root. Coughing, sneezing or voluntary contraction of abdominal muscles often elicits radiating pain. Defect in the neck of the Scottie dog on oblique x-rays Mechanical Back Pain No obvious pathology following trauma or progressive onset. But major cause of people off-work etc Spinal movement is complex there are many components that could cause pain Not related to old age: most common in 25 60 year olds Patterns: Disc Pain Facet Joint Pain Nerve Root Pain Spinal Stenosis Location of Worst in back. Pain worse bending backwards Presentation: midline pain radiating to groin or buttock, worse towards the end of the day, aggravated by coughing or sneezing. Straight leg raising is normal Treatment: analgesics, physio, spinal fusion Acute lumbar disc prolapse: Nucleus pulposis extrudes into a fissure in the annulus and bulges beneath the posterior longitudinal ligament: Pressure on ligament back ache Pressure on dural envelope of the nerve root pain referred to lower limbs (sciatica) Compression of nerve root paraesthesia and muscle weakness Posture: stand forwards and sideways tilt Sudden onset lasting for hours/days. Local tenderness and loss of spinal mobility Differential: Inflammation (eg due to Ankylosing Spondylitis or Tb) Vertebral tumours constant pain Nerve tumours cause sciatic but constant pain X-ray to exclude bone disease. Conservative treatment Osteoporotic: painless or agonising localised pain that radiates around ribs and abdomen.

The total work done by the insect during each downward stroke is the product of force and distance asthma symptoms 7dpo purchase cheap proventil; that is asthma symptoms chart cheap proventil express, Work Fav d 2Wd (6 asthma upper respiratory infection purchase proventil cheap. Our insect makes 110 down- ward strokes per second; therefore, its power output P is 4 3 P 112 erg 110/sec 1. To obtain the moment of inertia for the wing, we will assume that the wing can be approximated by a thin rod pivoted at one end. The maximum angular velocity max can be calculated from the maximum linear velocity vmax at the center of the wing vmax max (6. When the wings are decelerated toward the end of the stroke, this energy must be dissipated. During the downstroke, the kinetic energy is dissipated by the muscles themselves and is converted into heat. The wing joints of these insects contain a pad of elastic, rubberlike protein called resilin (Fig. The kinetic energy of the wing is converted into potential energy in the stretched resilin, which stores the energy much like a spring. Using a few simplifying assumptions, we can calculate the amount of energy stored in the stretched resilin. Although the resilin is bent into a com- plex shape, we will assume in our calculation that it is a straight rod of area A and length. Furthermore, we will assume that throughout the stretch the resilin obeys Hookes law. This is not strictly true as the resilin is stretched by a considerable amount and therefore both the area and Youngs modulus change in the process of stretching. Typically, in an insect the size of a bee the volume of the resilin may be equivalent to a cylinder 2 102 cm long and 4 104 cm2 in area. We will assume that the length of the resilin rod is increased by 50% when stretched. Experiments show that as much as 80% of the kinetic energy of the wing may be stored in the resilin. The hind legs of the ea, for exam- ple, also contain resilin, which stores energy for jumping (see Exercise 6-3). Compute the force on the body of the insect that must be generated during the downward wing stroke to keep the insect hovering. Referring to the discussion in the text, compute the point of attachment to the wing of muscle B in Fig. Assume that the shape of the resilin in each leg of the ea is equivalent to a cylinder 2 102 cm long and 104 cm2 in area. If the change in the length of the resilin is 102 cm, calculate the energy stored in the resilin. How large would these pads have to be in order for them to store 1 enough energy for a m jump? In the next three chapters, we will discuss the behavior of liquids and gases, both of which play an important role in the life sci- ences. The dierences in the physical properties of solids, liquids, and gases are explained in terms of the forces that bind the molecules.
