The upper part of the pos­ The ligamenta fava, on each side, pass between the terior longitudinal ligament that connects en to the intra­ laminae of adjacent vertebrae (Fig. These thin, cranial aspect of the base of the skull is termed thetectorial broad ligaments consist predominantly of elastic tissue membrane (see Fig. Each ligamentum flavum runs between the poste­ rior surface of the lamina on the vertebra below to the External occipital anterior surface of the lamina of the vertebra above. The protuberance ligamenta flava resist separation of the laminae in flexion and assist in extension back to the anatomical position. The ligamentum nuchae is a triangular, sheet-like structure in the median sagittal plane: • The base of the triangle is attached to the skull, from the external occipitalprotuberance to the foramen magnum. The broad lateral surfaces andthe posterior edge of the ligament provide attachment for adjacent muscles. They attach from the base to the apex of each spinous process and blend with the supra­ spinous ligament posteriorly and the ligamenta flava ante­ riorly on each side. Ligamentum flavum Supraspinous ligament Interspinous ligament In the clinic Ligamenta fava The ligamenta fava are important structures within the vertebral canal. In combination, zygapophysial joint hypertrophy, ligamenta fava hypertrophy, and a mild disc protrusion can reduce the dimensions of the vertebral canal, producing the syndrome of spinal stenosis. Disruption of two columns is Vertebral fractures can occur anywhere along the highly likely to be unstable and requires fxation and vertebral column. At the time of injury, results in a signifcant neurological event and requires it is not the fracture itself but related damage to the fxation to prevent further extension of the neurological contents of the vertebral canal and the surrounding defect and to create vertebral column stability.

When they examples of this are the unifacetal and bifacetal cervical occur, they usually involve signifcant force. If a fracture occurs around the pars interarticularis, the vertebral body may slip anteriorly and compress the vertebral canal. In this view, the transverse process (nose), pedicle (eye), superior articular process (ear), inferior articular process (front leg), and pars interarticularis (neck) resemble a dog. A fracture of the pars interarticularis is visible as a break in the neckofthe dog, or the appearance ofa collar.

In some diseases antiviral compounds best order albendazole, the amount required for maintenance of the desired therapeutic effect is less than the dose needed to obtain the initial effect risk hiv infection kissing purchase discount albendazole on-line, and the lowest possible dosage for the needed effect should be determined by gradually lowering the dose until a small increase in signs or symptoms is noted hiv infection rates uk 2013 purchase 400mg albendazole with visa. The opposite situation exists with respect to the use of corticosteroids in the treatment of inflammatory and allergic disorders. The same total quantity given in a few doses may be more effective than that given in many smaller doses or in a slowly absorbed parenteral form. Severe autoimmune conditions involving vital organs must be treated aggressively, and undertreatment is as dangerous as overtreatment. To minimize the deposition of immune complexes and the influx of leukocytes and macrophages, 1 mg/kg/d of prednisone in divided doses is required initially. When large doses are required for prolonged periods of time, alternate-day administration of the compound may be tried after control is achieved. When used in this manner, very large amounts (eg, 100 mg of prednisone) can sometimes be administered with less marked adverse effects because there is a recovery period between each dose. When selecting a drug for use in large doses, a medium- or intermediate-acting synthetic steroid with little mineralocorticoid effect is advisable. Special Dosage Forms Local therapy, such as topical preparations for skin disease, ophthalmic forms for eye disease, intra-articular injections for joint disease, inhaled steroids for asthma, and hydrocortisone enemas for ulcerative colitis, provides a means of delivering large amounts of steroid to the diseased tissue with reduced systemic effects. Beclomethasone dipropionate, and several other glucocorticoids—primarily budesonide, flunisolide, and mometasone furoate, administered as aerosols—have been found to be extremely useful in the treatment of asthma (see Chapter 20). Beclomethasone dipropionate, triamcinolone acetonide, budesonide, flunisolide, and others are available as nasal sprays for the topical treatment of allergic rhinitis. They are effective at doses (one or two sprays one, two, or three times daily) that in most patients result in plasma levels that are too low to influence adrenal function or have any other systemic effects. Corticosteroids incorporated in ointments, creams, lotions, and sprays are used extensively in dermatology. Recently, new timed-release hydrocortisone tablets were developed for the replacement treatment of addisonian and congenital adrenal hyperplasia patients. These tablets produce plasma cortisol levels that are similar to those secreted normally in a circadian fashion. Its actions, effects, and metabolism are qualitatively similar to those described below for aldosterone. Independent variations between cortisol and aldosterone secretion can also be demonstrated by means of lesions in the nervous system such as decerebration, which decreases the secretion of cortisol while increasing the secretion of aldosterone. Physiologic and Pharmacologic Effects Aldosterone and other steroids with mineralocorticoid properties promote the reabsorption of sodium from the distal part of the distal convoluted renal tubule and from the cortical collecting tubules, loosely coupled to the excretion of potassium and hydrogen ion. Sodium reabsorption in the sweat and salivary glands, gastrointestinal mucosa, and across cell membranes in general is also increased. Excessive levels of aldosterone produced by tumors or overdosage with synthetic mineralocorticoids lead to hypokalemia, metabolic alkalosis, increased plasma volume, and hypertension. Mineralocorticoids act by binding to the mineralocorticoid receptor in the cytoplasm of target cells, especially principal cells of the distal convoluted and collecting tubules of the kidney. The drug-receptor complex activates a series of events similar to those described above for the glucocorticoids and illustrated in Figure 39–4. It is of interest that this receptor has the same affinity for cortisol, which is present in much higher concentrations in the extracellular fluid. The specificity for mineralocorticoids in the kidney appears to be conferred, at least in part, by the presence of the enzyme 11β- hydroxysteroid dehydrogenase type 2, which converts cortisol to cortisone. The latter has low affinity for the receptor and is inactive as a mineralocorticoid or glucocorticoid in the kidney. Metabolism Aldosterone is secreted at the rate of 100–200 mcg/d in normal individuals with a moderate dietary salt intake. The half-life of aldosterone injected in tracer quantities is 15–20 minutes, and it does not appear to be firmly bound to serum proteins. The metabolism of aldosterone is similar to that of cortisol, about 50 mcg/24 h appearing in the urine as conjugated tetrahydroaldosterone. Fludrocortisone This compound, a potent steroid with both glucocorticoid and mineralocorticoid activity, is the most widely used mineralocorticoid. Although these androgens are thought to contribute to the normal maturation process, they do not stimulate or support major androgen- dependent pubertal changes in humans.

However, the use of neuromuscular blockers is making an es- sential contribution to risk reduction in modern anesthesia. In the following, some special methods of anesthesia are consid- ered before presentation of the anesthetic agents. Neuroleptanalgesia can be considered a special form of combination anesthesia: the short-acting opioid analgesic fentanyl is combined with a strongly sedating and af- fect-blunting neuroleptic.
