Given the observation that intermediate steps are time consuming with limited added value and also with increased awareness of the importance of early treatment of seizure, a change to accelerated protocol has been proposed. Lorazepam and phenytoin are given simultaneously, followed by pharmacologic coma (omit phenobarbitone).

This event is used sometimes to demarcate the transition from systole to diastole in the cardiac cycle hair loss in men 20s 1 mg finasteride with visa. The difference in the volume of blood in the ventricle at the end of diastole hair loss at 20 cheap finasteride 5 mg otc, or the end-diastolic volume hair loss lexapro buy 1mg finasteride amex, and the volume of blood in the ventricle at the end of systole, or the end-systolic volume, is called the stroke volume. Stroke volume represents the volume of blood ejected with each contraction of the ventricles (see Fig. At the end of systole, a significant volume of blood remains in the ventricles and is called the residual volume. Residual volume is decreased by increases in myocardial contractility and heart rate and increased whenever the heart is weakened (e. Thus, examination of end-systolic volume is useful clinically as an indicator of potential abnormal conditions affecting the heart. Ventricular diastole consists of isovolumic relaxation followed by a rapid, then reduced, filling phase. During the relaxation, or diastolic, phase of the cardiac cycle, volume and pressure changes proceed in the reverse of that seen for systole. Early in left ventricular relaxation, the aortic and mitral valves are closed, and the ventricle relaxes isovolumetrically. Once ventricular pressure falls below that of the left atrium, the mitral valve opens and the filling of the ventricle begins. Just prior to this occurrence, abrupt cessation of ventricular distention and the deceleration of blood create a faint third heart sound not normally heard in healthy people. However, the third heart sound is amplified in abnormally stiff or distended ventricles, such as that associated with heart failure, and its presence is therefore considered a serious sign of underlying cardiac abnormalities. During diastole, the ventricles fill in a rapid filling phase, followed by a reduced filling phase (rapid ventricular filling and reduced ventricular filling phases). During rapid ventricular filling, ventricular pressure actually continues to decline because ventricular relaxation occurs more rapidly than does the filling of the ventricle. During the reduced filling phase, sometimes called diastasis, ventricular pressure starts to increase. Atrial contraction produces a faint fourth heart sound that is amplified with A–V valve stenosis or with stiff ventricles. Abnormal conditions in heart valves are revealed by changes in venous pressure waveforms. Occasionally, pressure waveforms in the jugular vein are depicted on cardiac cycle diagrams. When the right atrium contracts, a retrograde pressure pulse wave is sent backward into the jugular vein. Factors that impede the flow of blood from the atria to the ventricles, such as tricuspid valve stenosis, increase the amplitude of the A wave. A second venous pulse wave, called the C wave, is seen as an increase followed by a decrease in venous pulse pressure during the early phase of systole. The upslope of this wave is created by the bulging of the tricuspid valve into the right atrium during ventricular contraction, which sends a wave into the jugular vein. This wave is combined with a lateral transmission of the carotid systolic arterial pulse to the adjacent jugular vein. The subsequent decrease in pressure in the C wave is caused by the descent of the base of the heart and atrial stretch. Failure of the tricuspid valve to completely close during ventricular systole results in the propulsion of blood back into the atrium and vena cava and results in a high-amplitude C wave. The V wave of the venous pulse is seen as a gradual pressure increase during reduced ejection and isovolumic relaxation followed by a pressure decrease during the rapid-filling phase of the cycle. This wave is created first by continual peripheral venous return of blood to the atrium against a closed tricuspid valve followed by the sudden decrease in atrial distention caused by rapid ventricular filling. Tricuspid valve stenosis increases resistance to the filling of the right ventricle, which is indicated by an attenuation of the descending phase of the V wave. Analysis of venous waveforms along with skilled attention to analysis of heart sounds was once used to provide clinical insights into cardiovascular disease involving cardiac valves.

The hallmark of diabetic macrovascular disease is accelerated atherosclerosis affecting the aorta and large and medium-sized arteries hair loss cure xa purchase finasteride 5mg free shipping. Renal atherosclerosis and arteriolosclerosis is due to macrovascular disease in diabetics hair loss weight loss discount 5mg finasteride fast delivery. A characteristic feature of renal involvement in diabetics is Hyaline arteriolosclerosis affecting both the afferent as well as the efferent arterioles hair loss zoloft buy discount finasteride online. However, the affected vessels (diabetic capillaries) are having increased permeability to plasma proteins. The microangiopathy is responsible for the development of diabetic nephropathy, retinopathy, and some forms of neuropathy. Clinical features include microalbuminuria (urinary Diabetic nephropathy excretion of 30-300 mg/dayQ of albumin). Diabetic retinopathy Most common lesion: Diffuse Glomerulosclerosis The ocular involvement may present as retinopathy, cataract formation, or glaucoma. Retinopathy is the most common pattern and can be of the following types: nonproliferative (background) retinopathy and proliferative retinopathy. Nonproliferative retinopathy includes intraretinal or pre-retinal hemorrhages, retinal exudates, microaneurysms (saccular dilations of retinal choroidal capillaries), venous dilations, edema, and, most importantly, thickening of the retinal capillaries (microangiopathy). The retinal exudates can be either “soft” (microinfarcts) or “hard” (deposits of plasma proteins and lipids). Peripheral, symmetric neuro- Macular involvement can cause blindness whereas vitreous hemorrhages can result pathy of the lower extremities from retinal detachment. The most frequent pattern of involvement is a peripheral, symmetric neuropathy of the lower extremities that affects both motor and sensory function. It can also manifest as autonomic Concept neuropathy (can produce disturbances in bowel and bladder function) and diabetic Dawn phenomenon is an early mononeuropathy (can manifest as sudden foot drop, wrist drop, or isolated cranial morning rise in plasma glucose nerve palsies). The neurological changes may be due to microangiopathy, increased requiring increased amounts of permeability of the capillaries supplying the nerves and direct axonal damage due insulin to maintain euglycemia. The delayed gastric emptying is called diabetic Somogyi effect is rebound gastroparesis and is managed with metoclopramide or erythromycin. These benign tumors may be responsible for the elaboration of suffcient insulin to induce clinically signifcant hypoglycemia. There is a characteristic clinical triad resulting from these pancreatic lesions: 1. The attacks consist principally of such central nervous system manifestations as confusion, Insulinomas are the most stupor, and loss of consciousness common pancreatic endocrine 3. The attacks are precipitated by fasting or exercise and are promptly relieved by feeding or neoplasms; characterized by. Hyperinsulinism may also be caused by diffuse hyperplasia of the islets which is usually seen in neonates and infants. Surgical removal of the tumor is usually followed by prompt Nesidioblastosis is diffuse islet reversal of the hypoglycemia. Thyroid hormones are required for the development of brain and maintenance of basal metabolic rate whereas calcitonin is involved in calcium homeostasis. The two types of disorders associated with this gland are hyperthyroidism and hypothyroidism. It should be differentiated from thyrotoxicosis which is a hypermetabolic state due to elevated levels of free T3 and T4 (so, thyrotoxicosis includes hyperthyroidism as well as other causes). Diffuse toxic hyperplasia (Graves’ disease) (Accounts for 85% of cases) enous thyroid hormone induced 2. It is the most useful screening test as its level may be altered in patients with even subclinical hyperthyroidism. This can result in cretinism in children and myxedema (or Gull disease) in areas of the world. The clinical features of the disease include lethargy, sensitivity to cold, reduced cardiac output, constipation, myxedema [due to accumulation of glycoaminoglycans, proteoglycans and water resulting in deep voice, macroglossia (enlarged tongue) and non- pitting edema of hands and feet] and menorrhagia (increased menstrual blood loss). It is more commonly seen in females (F: M ratio is 10:1) of the age group of 45-65 years. Increased susceptibility to Hashimoto’s thyroiditis has been associated with polymorphisms of cytotoxic T lymphocyte cause of hypothyroidism in are- as having suffcient iodine levels. Pathogenesis: There is replacement of the thyroid cells with lymphocytic infltration and fbrosis. There is presence of well Concept developed germinal centers and extensive infltration of parenchyma by mononuclear infammatory The fbrosis does not extend cells like lymphocytes and plasma cells.
