A patient with a normal cervical spine should be able to make firm contact between the chin and the chest or come very close to it allergy symptoms headache sore throat zyrtec 10 mg amex. Measuring the distance between the chin and the chest at the point of maximal flexion is the most useful way to quantify this movement for future comparison allergy shots red vial zyrtec 10mg cheap. To assess extension allergy under eyelid discount zyrtec 5 mg overnight delivery, the patient is asked to tilt the head back and to look up toward the ceiling new allergy medicine just approved by fda cheap 10mg zyrtec visa. Maximum extension is a combination of cervical allergy shots im or sq purchase zyrtec 10 mg with visa, thoracic allergy testing on infants zyrtec 10mg mastercard, and occipitocervical motion. If normal extension is present, the patient should be able to tilt the head back until the face is parallel with the ceiling. The amount of extension may be reduced in the presence of degenerative arthritis or a Cervical and Thoracic Spine 305 F i g u r e 8 - 1 2. In addition, acute cervical nerve root compression may also limit extension owing to pain. To measure lateral rotation, ask the patient to rotate the chin laterally toward each shoulder, in turn. The spinous processes are seen to rotate away from the side to which the chin points. This is best assessed by standing in front of or directly behind the patient and observing the arc of rotation as the head moves. Approximately 50% of normal rotation occurs between C1 and C2, the atlas and the axis. Lateral bending to both the right and the left sides is assessed by asking the patient to attempt to touch each ear to the ipsilateral shoulder. When combined with a normal shoulder shrug, maximal lateral bending should permit the shoulder to nearly touch the car. The amount of motion may be quantitated by measuring the distance between the shoulder and the ear at maximal effort or by estimating the angle that the midline of the face makes with the vertical. In dramatic contrast with the cervical spine, the thoracic spine permits little motion. To assess flexion and extension of the thoracic spine, the patient is seated against a straight-backed chair in order to eliminate lumbopelvic motion. The small amount of motion present may be detected by observing the change in relationship between the thoracic spine and the vertical chair back. In the presence of ankylosing spondylitis, the range of flexion and extension of the spine is limited. A traditional way to detect this stiffness when ankylosing spondylitis is suspected is to use a tape measure to assess the apparent change in length of the spine between flexion and extension. This is done by measuring the distance between the vertebra prominens and the sacrum with a tape measure when the patient is standing erect. The patient is then instructed to bend forward as far as possible, and the same interval is measured. A variant of this technique is the modified Schober test, which quantifies lumbosacral flexion. Another screening test for ankylosing spondylitis is to measure the amount of chest expansion possible. The patient is then asked to maximally exhale and the chest circumference is noted. Next, the patient is asked to maximally inhale and the circumference again is documented. This measurement is more difficult to perform in females, in whom ankylosing spondylitis is fortunately less common. The patient is then asked to maximally Hex, and the examiner measures the distance between the same two points. Normally, the length of the dorsal aspect of the spine should appear to increase about 6 cm. Excursion of much less than this amount suggests Palpation has several uses in the evaluation of the cervical spine. First, it may reveal a subtle deformity or malalignment that was overlooked during inspection or hidden from visual examination because an acutely injured patient was encountered in a supine position. Such spasm may reflect injury to the muscle itself or may merely be an involuntary response to a painful condition involving adjacent structures. Point tenderness may allow the examiner to identify the level of a discrete lesion or even the exact site of injury, such as a posterior facet joint. The supine position allows the patient to relax more completely and may, thus, permit the identification of more anatomic detail. The disadvantage of the supine position is that the examiner cannot directly visualize the structures being palpated. The prone position, although not widely employed, permits a compromise between the two extremes. If the patient is initially seen in an emergency situation, such as on an athletic field or following a motor vehicle accident, the question of preferred position is moot. In the emergency situation, the patient should be examined in the position in which he or she is first encountered until the examiner is satisfied that the possibility of an unstable cervical spine has been ruled out. If the examiner is unable to make this decision with confidence, the patient should be transported to a hospital with the neck immobilized until a good radiographic evaluation can be conducted. An acute lateral shift between two spinous processes may be due to a unilateral facet joint dislocation or fracture. An increase in the space between two otherwise normally aligned spinous processes raises the possibility of a posterior ligamentous disruption or fracture. The nuchal ligament connects the cervical spinous processes, beginning at the base of the skull and extending to C7. Conversely, the proximal spinous processes are easier to palpate when the cervical spine is extended. Owing to the overlying musculature, firmer palpation is needed to appreciate the resistance of the underlying bony structures. Although the specific outlines of the individual joints cannot usually be appreciated, the identification of localized tenderness over one of these joints may allow the examiner to identify the site of arthritic degeneration or ligamentous injury. While palpating lateral to the midline, the examiner also is able to evaluate the posterior cervical musculature, consisting of the upper portion of the trapezius and the underlying intrinsic neck muscles. Occasionally, a localized mass owing to a hematoma or other lesion may be palpable. Muscle spasm may indicate injury to the muscle itself, or it may be an involuntary reaction to pain in an adjacent structure. Cervical spine pain may be referred to portions of the trapezius, either superior to the spine of the scapula or between the thoracic spinous processes and the medial border of the scapula. The splenitis capitis and other members of the transversocostal group are partly covered by the upper trapezius, but they may be palpated more distinctly in the proximal neck where they are exposed lateral to the trapezius. The deeper transversospinal group is not distinctly palpable but may contribute to the apparent tenderness of the overlying musculature. Deep to the trapezius at the base of the skull lie the suboccipital muscles, the rectus capitis (posterior) major, the rectus capitis minor, and the obliquus capitis superior and inferior. The greater occipital nerve, also known as the suboccipital nerve, traverses the triangle formed by these muscles. Tenderness in this area may be due to occipital neuritis, muscle strain, or, in cases of rheumatoid arthritis, potential C1-C2 instability. Because of this, major injuries here require substantially more energy than in the cervical Figure 8-20. Palpation of the cervical spine usually begins at the inion, located at the base of the skull. Palpation proceeds distally toward the more prominent C7 and Tl spinous processes. The examiner should ask the patient whether gentle pressure on each of the spinous processes is painful. In the emergency situation, documentation of localized tenderness is sufficient reason to consider the cervical spine potentially unstable and to immobilize and transport the patient accordingly. In addition to palpating each of the spinous processes for tenderness, the examiner should also use palpation to evaluate their alignment. However, palpation of the thoracic spine may be used to detect localized tenderness or discontinuity just as in the cervical spine. When not readily visible, the hyoid bone, the thyroid cartilage, and the cricoid cartilage can be gently palpated. The primary purpose of identifying these structures is to orient the examiner to the corresponding vertebral level of spinal pathology. The hyoid is a horseshoe-shaped bone that lies just caudal to the angle of the mandible at about the level of the C3 vertebral body. The examiner may gently grasp this firm curved structure between the thumb and the index finger. Inferior to the thyroid cartilage is a narrow groove followed by the prominent curved band that is the anterior F i g u r e 8 - 2 2. Direct gentle posterior pressure should result in the detection of the tubercles of Chassaignac, or carotid tubercles, located on C6. The examiner should take care not to compress both carotid arteries simultaneously. Strength testing of the muscles that move the cervical spine is not usually emphasized as much as the evaluation of the muscles that are innervated by the various cervical nerve roots. Nevertheless, it is important to establish that the protective function of the intrinsic cervical musculature is present. In addition, the identification of specific weak muscle groups, although not as significant as the identification of a specific central or peripheral neurologic deficit, may allow the clinician to formulate a treatment plan to restore normal function. All strength testing should be done gently, with the examiner providing firm, controlled resistance. Because they are innervated by the spinal accessory nerves, a complete injury to one of these nerves would paralyze the corresponding sternocleidomastoid muscle. Again, the examiner should be unable to overcome the normal intrinsic muscle strength of the neck extensors. Neurologic function is best evaluated in a systematic examination organized by dermatomes. The sensory, motor, and reflex tests for each dermatome are summarized in Table 8 - 1. Because the most common neurologic deficit associated with cervical spine disorders is a radiculopathy, such a systematic examination allows the clinician to identify the specific nerve root involved. In the case of more extensive deficits associated with spinal cord injuries, this same examination allows the clinician to determine the neurologic level of deficit. Neurologic Examination A thorough neurologic examination is a basic part of cervical and thoracic spine evaluation. Testing for light touch is a good screening tool for assessing the distribution of a sensory loss in order to characterize it as radicular, nonradicular, or global. A nonradicular sensory loss suggests a more peripheral nerve injury; the involved area is more diffuse and overlaps several dermatomes. A glove or stocking distribution of sensory dysfunction signifies a circumferential sensory deficit in the entire portion of the involved limb distal to a certain point. Conditions that may be associated with a glove or stocking sensory deficit include diabetic peripheral neuropathy, reflex sympathetic dystrophy, and nonorganic disorders. The examiner strokes the area in question as well as adjacent areas and asks the patient to acknowledge each touch. In this manner, the examiner Cervical and Thoracic Spine 315 can gradually delineate an area that is anesthetic or hypoesthetic. The abnormal area can be marked on the patient and compared with diagrams of dermatomes and the sensory distribution of peripheral nerves. For more precise testing, special filaments made expressly for this purpose may be used. Sharp-dull discrimination testing may be used to confirm the results of a light touch examination. In this case, the patient is asked to identify whether the area being examined is being touched with the sharp or dull end of a safety pin. This distinction should normally be an easy one for the patient to make; in an area of diminished sensation, the patient has difficulty distinguishing between sharp and dull. Vibration sense can be tested using a tuning fork of 256 Hz over bony prominences such as the humeral epicondyles or the radial styloid. The most sensitive means of assessing sensory loss in the upper extremities is twopoint discrimination testing. A subject with normal sensation should be able to distinguish points 5 mm apart on the fingertips. The technique for assessing two-point discrimination is described in Chapter 1, Terms and Techniques. The approximate areas of sensory innervation from the cervical and thoracic nerve roots are shown in Figure 8-29. There is considerable overlap in the sensory dermatomes, and the exact distribution of each dermatome varies somewhat from one individual to another. Sensory deficits are usually sought by evaluating sensation in relatively small areas that can reliably be expected to correspond to specific dermatomes in most individuals. The C5 nerve root can be evaluated by testing sensation over the middle deltoid. The C6 nerve root supplies the dorsum rests the base of the vibrating fork on the bony prominence and asks the patient to report when the vibration stops. Otherwise, loss of vibration sense is associated with injury to the posterior columns of the spinal cord or peripheral nerves. Loss of proprioception, also a sign of posterior column dysfunction, may be associated with aging, injury, or cerebellar dysfunction. The examiner then alternately flexes and extends the digit several times, randomly stopping in flexion or extension.
Voit) in the possibility of fattening animals on purely proteid diet (Voit allergy symptoms with fever buy zyrtec 10 mg with amex, Pettenkofer allergy forecast midland tx buy 10 mg zyrtec visa, Cremer) allergy medicine can i give my dog buy generic zyrtec 10mg online. Thus glycogen may be formed from; proteid by metabolic changes and the possibility of fat production from this polysaccharid must be apparent or bacterial agency of the many instances allergy forecast atlanta ga purchase zyrtec 5 mg overnight delivery. The substance fat allergy symptoms on lips order zyrtec 5mg with amex, may be assumed in bacteria may here be held a possible source of and allergy shots given intramuscular cheap zyrtec 10 mg with amex, too, their enzymes seem capable of splitting the proteid molecule, with possible ultimate fat formation. In one of these indirect modes it may be accepted that fat may be produced from proteid and to whatever degree these may apply to pathological changes in the living body it may be held that the fat in question may have had an original proteid origin. There is another possibility, related, it is true, with the following paragraph, but not distinctly indicated by Professor Kitt, which should be held as a possible explanation of the appearance of fat in fatty degenerated cells. Fat combined in the general protoplasmic molecule may exist without being visible in case of disintegration of the protoplasm this combined fat may be set free and be;; come apparent. And at last from the standpoint of application cell to the clinical is importance of the case, the really important point the discovery of the fat in the is not so much as it is the fact that the cell undergoing a disintegrating process and it is this which should always be kept in mind. Whatever be the theoretical claims for considering fatty infiltration and fatty metamorphosis together, the student should, for practical purposes, hold them clearly sep- - the Fatty Changes. The relation between pathological fatty degeneration and metabolic faults is apparent, moreover, in the fact that it is especially likely to occur process is essentially whenever the processes of oxidation are impaired in the body as in all disturbances accompanied by diminution in the red cells or in the haemoglobin of the blood, the means of oxygen distribution in general oligaemia caused by blood loss or affections of the alimentary tract in parasitic anaemias and in local anaemias in the fatty changes commonly resulting from imperfect vascularization and its accompanying local anaemia, particularly in rapidly growing tumors (carcinoma and sarcoma). Destruction of the erythrocytes and consequent diminution of the oxygen content of the blood, or, too, reduction in oxygen appropriation by the cells of a tissue because of some alteration, may result from various toxic causes;;; in these there arise, as important or associated lesions, fatty dekidneys, generation of the It sets in liver, myocardium and other structures. In regard to excess of fat in the tissue there docs not obtain any sharp limit between the physiological and pathological grades. Inasmuch as this loss is- immediately removed by feeding ovariin to females and spermin and didymin to males after castration, and the followed; same disturbances recur after stopping the administration of these substances, it may be assumed that the sexual glands possess a chemical function in connection with metabolism. When obesity is referable to an especially rich supply of fat or fat-forming substances animals are said to be 'fattened" (dietary obesity, obesitas ex alimcntis). It is well known that this is favored by repeated venesection; the lowering of gaseous exchange from the removal of blood corpuscles may be a factor in this case. Sometimes the discoloration is in destruction which is taking place], a pasty, streaks or flecks. The process may if be associated with cloudy latter degenerative swelling, when the parts look as they had been cooked [and are apt to be of increased volume from the change] the pathological significance of fatty infiltration and of fatty degeneration depends upon the extent and intensity of the process ber. Even fatty degeneration is recoverable extent from remaining normal cells or nuclei (mitotic nuclear figures have been found in fatty degenerated cells (Ribbert), and the ordinary recovery from the infectious diseases in which muscular and hepatic fatty metamorphosis is apt to occur would substantiate this view). The massive increase of adipose tissue in the body may be harmful to the rest of the tissue elements from the mechanical effects of diminishing space and compressing the cells against each other, as in the heart, where in case of excessive fatty infiltration the fat penetrates between the cardiac muscle fibers. Liver cells, which are the seat of marked fatty infiltration and consequent enlargement, compress the capillaries distributed between the cell columns, and in this way give rise to anaemia and its results. Both cells and tissues are rendered softer and more friable by fatty degeneration and this diminution of resistive power against mechanical influences may have serious consequences, as rupture of a degenerated liver or of arteries with degenerated walls from increased blood pressure. Advanced grades of fatty degeneration have, as might well be expected, a serious influence upon cellular function apart from the fact that this process is in itself an indication of pathoFor example, an logical disturbance of the cellular protoplasm. In exceptional circumstances the process to effect may be distinctly favorable to efforts the recovery, facilitating resorption or removal of in- jurious substances like tumors or foci of purulent softening in the tissues. The transformation geneous, glassy of a tissue into a microscopically colorless homo- and highly refractile coagulum is known as hyaline degeneration. There are produced as a result of this change one or more types of albuminates, separable chemically from each other with difficulty, the substance, or transparent, 200 hyaline to acids, (v. Recklinghausen), being characterized by brilliantly stained its resistance by being uninfluenced by water, alcohol or ether, and by it the fact that is with acid aniline dyes (eosin, orange) and with carmine. This degeneration, or, as Diirk calls it, homogenization, occurs to them; according to Ribbert as a local metabolic disturbance, in which the tissues do not properly use up the proteid supplied it do not assimilate it all or throw is off before all it is completely converted. Such substance themselves then precipitated through the tissue overlying is the intercellular substance and destroying the latter and the cells (Ribbert). Hyaline formation met principally in connective tissue and the vascular apparatus, in hemorrhagic and infarcts, anaemic thrombi, false membranes, in the areas of caseaand in the connective tissue of tuberculous lymph glands, in neoplasms and to some extent the tion; substance product, occurs as as a secretory cylinders the hyaline of the uriniferous tubules. The relation of to hyaline Muscle ten of degeneration as coagula- tion necrosis horse after b. Thus, the hyaline met dense connective tissues as scars, walls of sclerotic blood vessels, usually regarded as the typical form, the fibrous tissue here etc. Definite fibrinous exudates, as that of pleurisy or pericarditis, and that of false membranes, as of diphtheria, sometimes undergo a similar change (exudative hyaline), losing the reticular appearance of the earlier stages and presenting all uniformly glass-like sheets or bands or clumps of hyaline matter. Within tumors, especially sarcomata, hyaline matter is often found in; some of the sarcomata mantles of the substance form over In various changes and in the blood vessels or actually involve the vessels and render them impervious (cylindromata). The same neoplasms bodies are not very uncommon in within the various not subjects cells, as those of the liver or (intracellular kidneys, hyaline). The cause of nutrition of the change in a broad sense includes disturbances and the influence of local intoxications, but the details of the action of these and of the development of hyaline and hyaloid substances are confused and largely wanting. The change is probably often that of a true coagulation necrosis in some forms; it involves further alterations of coagulated matter; in others it evidently does not mean the necrosis of the cells involved, but by is its advance leads to their death, and sis. There is no evidence that substance indi- vidual cells containing small globules of hyaline it, are seriously incommoded by is it is although the part of the cellular proif toplasm thus affected involved probably useless and the cells be greatly probably eventually a serious lesion. Increased secretion of mucus from cells occurs for the most part as one of the phenomena of inflammatory irritation, the fluid, mucus appearing as an accumulation of a ropy resembling the albumen of an egg (mucous catarrh), sometimes more or less clouded from the admixture of desquamated and exuded cells. In connective tissue, cartilage and bone, the occurrence of mucus causes a gelatinous swelling, an appearance suggestive of head cheese. Under the microscope mucus may be recognized as transparent droplets coalescing into clumps (mucous spheroids), usually fairly definite outlines. The cells in which the mucus is generally swell up in one part, the mucin causing some deformation from pressure, flattening it and pushing it the having formed nuclear toward the base of the cell (transformation of cylindrical cells into goblet cells); mucus seems to originate from the nucleus in the form of thrown (hyalosomes), which take a uniform blue color with hematoxylin and respond a chromatic substance off in small globules to the xanthroproteic test (yellow coloration with nitric acid). The first the third and second are usually found as products of epithelial cells; is more apt to be met of all, in mucoid degeneration of connective a tissue. Mucoid degeneration structive of tissues should be considered as a de- change; but the increased secretion of mucus may have a favorable influence in pathological conditions, by the envelopment of harmful corpuscular agencies irritation (dust particles, and thus preventing inflammatory bacteria from the bronchial tubes, larynx, pharynx and nose). The substance differs from mucus, however, in being completely soluble in acetic acid after a preliminary swelling. This substance is normally found in the thyroid and adrenal cysts in the prostatic glands. The substance is an albuminate of uncertain and probably variable com(or spaces position. Its stiff gelatinous consistency, brownish-yellow color and transparency, together with the other features above mentioned, grossly differentiate it from mucus and the hyaline substance. Microscopically the material is of a transparent, structureless aptypically takes the acid stains. The cells thus affected are apparently not altered primarily and are affected mainly by the pressure of the collection of the colloid matter, which causes more or less atrophy. The glycogen which is physiologically stored up in the liver and which is also met in muscle, kidneys, uterus, placenta, cartilage, squamous epithelium and in all of the organs of the foetus, may, when circulating in abnormal amount in the blood (diabetes mellitus) be found in still other cells, being present in considerable proportions in such circumstances in the leucocytes and renal epithelial cells. It is also found in pus corpuscles in suppurative affections, and in tumors of embryonic derivation the cells contain glycogen. This be conre- dition can scarcely garded as a special degeneration, as the cells glycogen-bearing of show no other features alteration. The glycogen in exists in the cells merely the form of globules of staining larger or smaller size, clumps or granules, brown with iodine and readily soluble in water (or saliva). The name amyloid (amyliim, plied starch; eUos, nature of) a was apreaction similar by Virchow with to a substance which gives color when treated iodine and sulphuric acid somewhal 2o6 to that of starch Retrogressive Processes s [when treated with iodine alone], and which as the result is found in the tissues of a special process of meta- morphosis. The reasons for this view are, it is true, not absolutely convincing, but are suggestive. The material may ried in accordance with this idea be supposed to exist in the blood or elsewhere in a soluble pre-amyloid state and to be car- by the blood to be deposited in its favorite seat, the walls of arteries, where for some unknown local cause it is precipitated as amyloid matter. Its common occurrence in the walls of arteries rather than those of veins, its appearance in masses in intercellular positions where normally there scarcely exists material which could by any known mode of transformation assume the size of the common amyloid masses (as between the basement membrane and epithelium of the renal tubules), are the principal basis for this opinion. Amyloid is colored yellow by nitric acid, indiits cating by this xanthoproteic reaction albuminous nature. According to the investigations of Krawkow this substance is a compound of an albuminate with chondritin-sulphuric acid. This latter substance, to which the iodine reaction is mainly due (Ribbert) is found normally in cartilage and elastic tissue. Amyloid material, as such, does not exist normally in any part Amyloid Infiltration. In man aside more commonly seen in man than in an ordinary accompaniment of advanced its tuberculosis, from as a occurrence in chronic suppurations it but it is usually absent in this connection in animals, although has been observed culosis in it degenerative Roll, accompaniment of tuberobservations). Organs, the seat of amyloid enlarged inelastic; infiltration, their consistence less is changed,; become considerably becoming dense and section is and In more or wax-like in the pale tissue is somewhat transparent and homogeneous, and anaemia. Microscopic study shows very clearly in these structures the and along the connective tissue elements of the larger blood vessels. In the advanced stages of the process the substance is seen in thick homogeneous, bulging and lumpy strands. The glandular cells and connective tissue corpuscles generally only suffer passively by pressure atrophy, that is, they do not themselves become amyloid Johne, however, states that in the horse the liver cells also become enlarged, lobular and shining and lose their nuclei, this indicating, deposition just outside the capillaries; therefore, their participation in the process. Amyloid especially in infiltration may also occur as a purely local process, the of connective tissue of tumors a and inflammatory substructure rich thickenings in elastic mucous membranes having as in tissue, the growths in the nasal mucous mem- branes of horses known as narioblastomata. The hyaline casts [waxy casts] forming in the urinary show amyloid reactions; tubules in inflammations of the kidneys sometimes so, round granules made up of epithelial conglomerations and showing a concentric structure, which are found in the prostate in man and in old dogs and octoo, the casionally in the miiller, ependyma of the cerebral ventricles (Bruck- these bodies are known as corpora amylacea or versicolorata in case they are colored brown, red and violet by tincture of iodine and sulphuric acid and as corpora Hava when they are merely turned yellow with iodine.

In infiltration progressive character the the marked increase of the volume most important factors in of the organ, the consequences of pressure atrophy on the paren- chymatous cells, constitute the pro- duction of immediate funtional disturbance of the organ. The entire lack of similarity to blood pigment, especially the absence of iron as a constituent, the pigment granules being, and containing nitrogen would in(v. It is not known whether the material employed in the pigment production is originally derived from the blood or whether it represents an excretory substance of the system and its production is comparable to the formation of humus it can only be said that in the same way as in early fcetal life and thence onward, formation of blood coloring matter takes place from the influence of cellular activity, or as, under the influence of light, chlorophyl formation is a form of cellular function, these pigments are dehowever, rich in sulphur,; veloped within the cells. Connective tissue cells have been noted in the human coriuni loaded with pigment and capable of movements which actually carry the pigment into the epithelial cells, and in some circumstances carry it away again (chromatophores) this has been observed particularly in connection with experimental transplantations; where a small bit of white skin has been grafted upon a black (negro), after healing it becomes as dark as the neighboring tissue from the penetration of chromatophores. In some of the domestic animals the congenital, brown, lentiginosis spots are, to Schindelka, quite according common; the condition known as melanosis maculosa in calves is especially frequent, such an excess of pig- ment cells existing congenitally that spots of inky blackness may be found in large numbers beneath the skin, between the muscles, beneath the pleura and in the lungs, in the epicardium, in the liver, in the submucosa of various mucous membranes and in the membranes of the central nervous system. In foci of local overof also seen in calves to production there may often be observed in sheep an excess the black pigment in the pia mater. There a is and in adult cattle rather frequently sepia-brown of the ebony of black color of the kidneys, which, from the studies of L. Tumors) is produced by metabolic acthe convoluted tubules tivity; the proliferating cells contain within the protoplasm brown and black granules in thickest profusion. According to the investigations of Berdez and Nenski the coloring matter of the melanotic tumors is rich in sulphur; it is known as hippomelanin and phymatorhasin. Haematogenous Pigmentation, Hcumochromatosis^ the color- - ing matter of the blood, haemoglobin, in haemolysis all conditions causing and washing out of red blood corand is partly distributed puscles, becomes freed from the cells in solution throughout the fluids and tissues, and may be in part precipitated, as is indicated by the pigmentation of the tissues. In the event of large numbers of red corpuscles undergoing or destruction; solution (haemolysis) within the blood passages, as in various the intoxications and infections (blood poisons, piroplasmosis), is coloring matter to (haemoglobin or methaemoglobin) transferred the blood plasma. The blood becomes lake-tinged, and the serum obtained after venesection from the clot is stained, instead of limpid and yellowish, a deep red (hcemoglobincemia) The. Precisely as in normal life, the dead blood cells and their remnants are taken up by leucocytes and carried to the lymph nodes, spleen, bone marrow and elsewhere ried; in cases of exaggerated destruction of the erythrocytes the same methods of transportation are car- on in greater measure, and the remnants of haemoglobin are deposited in the various organs in proportion as this blood refuse fails of complete destruction.

Tissues discolored by hemosiderin may become slate-colored or black- ened (formation of iron sulphide, pseudomelanosis) in places where they in contact with sulphuretted hydrogen (in the intestinal canal after death, or in ichorous cavities and putrefying hemorrhagic exudates). The common causes of such absorption of bile are diseases which occasion obstruction passage to the and therefore result in a biliary stasis {icterus from stasis), and all conditions which are accompanied by obstruction or narrowing of the biliary channels (obstruction from gall stones, compression by tumors, swelling of the mucous lining of the passages), providing the liver tissue meanwhile continues its production of bile. This may be observed under the microscope as an engorgement of the intraacinous biliary tubes which look as if actually injected with greenish bile substance and the stasis may be further traced into the intercellular secretory alveoli and; tubules. In case of rupture of these delicate capillaries the bile may ried gain entrance into the adjoining lymph-spaces, and be car- by way of the lymph channels into the blood (thoracic duct). Biliary stasis 213 depend upon an excessive production of the secretion, inasmuch as the profusely produced bile may also be sometimes too concentrated and thick and flow with difficulty, the cells in consequence becoming clogged. A hypercholia of this type occurs in conditions which cause a marked destruction of red blood cells, and the haemoglobin set free en masse is then worked over in the liver and renders the bile particularly rich in its pigmentary matter. It is possible, too, that the bile may be thickened and less fluid or may diffuse also directly into the blood vessels because of disease of the liver cells. It was formerly believed sufficient that the formation of biliary coloring matter in quantities in to cause jaundice could also take place outside and a hsematogenous jaundice was spoken of. From the studies of Minkowski and Naunyn, however, it may be considered established that, even in cases where a simple increase of destruction of erythrocytes causes this symptom, it is not produced except with the intervention of the liver, and that the transformation of the haemoglobin into biliary pigment is accomplished in the liver. Birds jaundiced by arseniuretted hydrogen rapidly lost their icterus after extirpation of the liver, and where the liver had been previously ablated, jaundice could not be produced in any degree at all. Although there may be more or less hsematoidin present, there the liver, the blood; are also less closely allied blood pigments. In the living body this is apt to be particularly conspicuous in the conjunctiva and sclera; in the dead animal the yellow color is principally apparent in the subtissues cutaneous tissues, lungs, liver the fat, intermuscular connective tissue, the and kidneys, the mucous membranes and their muscular coats. Where the normal color of an organ was pale the discoloration may take on an intense citron-yellow hue the dark liver and kidney tissue becomes saffron yellow to olive green or; greenish-black.

Since 1994, the field has gained additional insights about critical needs of women and children and the role that partners and fathers play regarding these needs. The knowledge gained in the past decade should drive the delivery of services to women. This is partly a result of the pressures of society, exemplified by welfare reform and data indicating that gainful employment can be a protective influence for preventing relapse. These needs are addressed when children are provided services directly, as well as when the needs of their parents are met. More than one-third of these children will not see their fathers at all during the course of a year. Studies show that children who grow up without responsible fathers are significantly more likely to experience poverty, perform poorly in school, engage in criminal activity, and abuse drugs and alcohol (U. This update to the model considers the needs of women, their children, and their families in the context of their community and culture. In addition to incorporating the new knowledge about the common histories and service needs of women and their children, this model goes a step further by delineating the relational elements of the service continuum that have an impact on treatment for women. Research has established that there are many paths to recovery from alcohol and drug problems. Some women resolve their alcohol and drug problems with individual and family supports and without any outside intervention. Others recover with support from self-help groups such as Alcoholics Anonymous and/ or the faith community. A variety of factors can influence which of these paths is successful, including the severity of the problems and the support systems available to women with substance use disorders. However, not all services and/or interventions are needed by every woman in treatment or recovery for substance dependence, and those who meet the diagnostic criteria for substance abuse may require a less comprehensive range of services than those who are substance dependent. Similarly, women with a range of family, social, and economic supports may not require a full complement of services while those who have fewer naturally occurring supports may require more services from the formal health, social, and economic supportive systems. The array of services described below does not need to be provided by a single entity, but in most instances will be provided by a consortium of addiction treatment, health, and human service providers. The continuum is not specific to philosophies of treatment and recovery, modality, or setting.
This reflex may be elicited in the patient who is seated with the legs dangling comfortably off the end or side of the examination table allergy symptoms treatment purchase zyrtec 10 mg mastercard. The examiner gently dorsiflexes the foot to place the Achilles tendon under tension allergy symptoms light headed discount 5mg zyrtec visa, and then strikes the Achilles about 3 cm above the calcaneus using the flat end of the reflex hammer allergy symptoms in dogs eyes buy zyrtec 5mg otc. In most patients allergy medicine plus decongestant purchase zyrtec 10mg mastercard, this action produces a visible twitch of the ankle into plantar flexion allergy symptoms hoarse voice safe 5 mg zyrtec. As with other deep tendon reflexes allergy forecast austin tx cheap zyrtec 5 mg online, a unilateral decrease in the magnitude of or disappearance of the Achilles reflex suggests a lower motor neuron lesion. The most common cause of this picture is a herniated L5-S1 disk impinging the ipsilateral S1 nerve root. If the examiner experiences difficulty in eliciting the Achilles tendon reflex, the use of reinforcement techniques is often helpful. A convenient method for reinforcing the Achilles tendon reflex is to ask the patient to kneel on the examination table with the feet projecting a few inches past the end or side. This technique brings out the Achilles tendon reflex in the vast majority of individuals. The details of these procedures are described in Chapter 8, Cervical and Thoracic Spine. It is important to remember that the spinal cord usually ends at the inferior margin of the L1 vertebra. Distal to this level, the nerve roots that constitute the cauda equina function very much like peripheral nerves. Thus, for an upper motor neuron picture to occur, a lesion must typically be situated at the L1 level or higher. Nerve Tension Tests An important component of the lumbar spine examination is to determine whether evidence of nerve root compression exists. Nerve root compression is usually considered probable when stretching the peripheral nerve associated with the nerve root in question reproduces pain in the distribution of that nerve. The most important peripheral nerves deriving from the lumbar and the sacral nerve roots are the femoral and the sciatic nerves. The femoral nerve runs down the anteromedial aspect of the thigh and is formed by the L2, L3, and L4 nerve roots. The sciatic nerve runs down the posterior thigh and is formed by the L4, L5, S1, S2, and S3 nerve roots. The test is performed with the patient lying in a comfortable supine position with the head and pelvis flat. The angle formed by the lower limb and the examination table at the point of maximal elevation is noted, and the procedure is repeated with the opposite limb. In the presence of sciatica, the angle of hip flexion is reduced and the patient reports shooting pain radiating down the posterior thigh and often into the lower leg along the distribution of the sciatic nerve. An abnormal straight-leg raising test, therefore, suggests a lesion of either the L5 or the S1 nerve root. If the patient with limited straight-leg raising reports tightness in the posterior thigh rather than sciatica, hamstring tightness is the probable cause. Hamstring tightness may be associated with a wide variety of conditions, including spondylolysis. Recent studies have confirmed that the straightleg raise test is extremely sensitive (0. Performing the straight-leg raising test on the side opposite that of the sciatica is called the crossed straight-leg raising test. While maintaining the degree of hip flexion at which sciatic pain is induced, the examiner passively dorsiflexes the foot of the leg being raised. The results of both the straight-leg raising test and the Lasegue test are abnormal in most cases of lumbar disk herniation, however. Digital pressure is then applied to the popliteal fossa over the posterior aspect of the sciatic nerve. Reproduction of familiar radicular pain, as in the straight-leg raising, Lasegue, and crossed straight-leg raising tests, is highly suggestive of sciatic nerve root tension. Subsequent extension of the neck relaxes the spinal cord and may thus relieve nerve tension. The slump test is a progressive series of maneuvers designed to place the sciatic nerve roots under increasing tension. The patient begins the slump test sitting on the side of the examination table with the back straight, looking straight ahead. The patient is then encouraged to slump, allowing the thoracic and lumbar spines to collapse into flexion while still looking straight ahead. The patient is then instructed to extend one knee, thus performing a straight-leg raise. The patient then dorsiflexes the foot on the same side, thus duplicating the Lasegue test. At each stage in the procedure, the patient informs the examiner what is being felt and whether radicular pain is produced. Many normal individuals feel tightness As noted, the straight-leg raising test and its variants do not place significant tension on the nerve roots above L5. Although compression of the upper lumbar nerve roots is not common, it does occur. The femoral nerve stretch test is designed to assess compression of the L2, L3, or L4 nerve roots. In the normal patient, this induces only a mild feeling of tightness in the anterior thigh. The single leg hyperextension test has been described as a more specific test to detect the presence of spondylolysis and to suggest which side is involved in the Figure 9-27. To perform the single leg hyperextension test, the patient is asked to stand in the straddle position with one lower limb extended behind the other. The patient is then instructed to lean back as far as possible, and the examiner assists the patient in achieving the maximal hyperextension of the spine possible without falling over. To perform the Valsalva maneuver, the patient is instructed to bear down as if attempting to have a bowel movement. If pain is present owing to pressure on the spinal cord or the nerve roots, this maneuver usually exacerbates the pain. The physical findings in c o m m o n conditions of the lumbar spine are summarized in Table 9 - 2. Spondylolysis Lumbar tenderness at the level of involvement (variable) Decreased lumbar lordosis (variable) Hamstring tightness with straight-leg raising test Pain exacerbated by hyperextension of the lumbar spine (passive extension, active extension, single leg extension test) (frequent) Signs of associated spondylolisthesis, if present Spondylolisthesis Signs of spondylolysis (see above) Visible or palpable lumbar step-off (more severe cases) Sciatic notch tenderness (variable) Motor or sensory deficit (variable) Lumbar Fracture Tenderness at the level of injury Localized swelling and hematoma or ecchymosis Lower motor neuron deficit owing to injury to the cauda equina or the nerve roots (variable) Upper motor neuron deficit if lesion above the level of the cauda equina Lumbar Spondylosis Decreased range of motion Pain exacerbated by motion (variable) Localized or diffuse tenderness (variable) Low-Back Strain Paraspinous muscle tenderness Paraspinous muscle spasm (variable) Symptoms exacerbated by forward flexion List (variable) Normal neurologic examination Examination of Other Areas and Systems Pain due to lumbar spine pathology frequently radiates to the pelvis, the posterior hip, or the thigh. In the case of lumbar disk disease, back pain may sometimes be completely absent, with the patient sensing pain only in the sciatic notch and the posterior thigh areas. Patients with this clinical picture often believe that they have a painful hip joint or a hamstring -strain. Complete investigation of potential l u m b a r spine pathology, therefore, often includes evaluation of the sacroiliac joint, the sacrum and the pelvis, the hip joint, and the thigh. The details of these related examinations are described in Chapter 5, Pelvis, Hip, and Thigh. Because the symptoms of claudication due to peripheral vascular disease are similar to those of pseudoclaudication associated with spinal stenosis, an examination of the peripheral circulation of the lower extremities is often a necessary adjunct to the lumbar spine examination. Lumbar spine examination should include careful inspection, gait, range of m o t i o n testing, and a t h o r o u g h neurologic examination. Palpation of the lumbar spine should be performed to identify any areas of tenderness or "step-off. Neurologic examination should include motor, sensory, and reflex testing in the distribution of the lumbar nerve roots. Nerve tension tests are helpful at identifying pressure on a nerve root such as t h a t caused by a herniated disk. The straight-leg raising test is more sensitive for nerve root compression, while the crossed straight-leg raising test is more specific.

As part of the clinical encounter, health care providers should routinely obtain sexual histories from their patients and address risk reduction as indicated in this report. Effective interviewing and counseling skills, characterized by respect, compassion, and a nonjudgmental attitude toward all patients, are essential to obtaining a thorough sexual history and delivering effective prevention messages. Effective techniques for facilitating rapport with patients include using open-ended questions. In addition, health care professionals can consider assessing sexual history by asking patients such questions as, "Do you have any questions or concerns about your sexual health Persons should be informed of their test results and recommendations for future testing. With the challenges that intensive behavioral counseling poses, health care professionals might find brief prevention messages and those delivered through video or in a group session to be more accessible for the client. Other approaches use motivational interviewing to move clients toward achievable risk-reduction goals. Clientcentered counseling and motivational interviewing can be used effectively by clinicians and staff trained in these approaches. Each latex condom manufactured in the United States is tested electronically for holes before packaging. The rate of condom breakage during sexual intercourse and withdrawal in the United States is approximately two broken condoms per 100 condoms. Rates of breakage and slippage might be slightly higher during anal intercourse (28,29). Users should check the expiration or manufacture date on the box or individual package. Latex condoms should not be used beyond their expiration date or >5 years after the manufacturing date. Condoms made of materials other than latex are available in the United States and can be classified into two general categories: 1) polyurethane, polyisoprene, or other synthetic condoms and 2) natural membrane condoms. These can be substituted for latex condoms by persons with latex sensitivity, are typically more resistant to deterioration, and are compatible with use of both oil-based and water-based lubricants. Natural membrane condoms (frequently called natural skin condoms or [incorrectly] lambskin condoms) are made from lamb cecum and can have pores up to 1,500 nm in diameter. Internal Condoms Condoms for internal vaginal use, also known as female condoms, are available worldwide. Although the internal condom also has been used during receptive anal intercourse, efficacy associated with this practice remains unknown (33). For men and transgender women who have anal intercourse, tenofovir gel appears safe when applied before and after anal sex (52). N-9 use also has been associated with an increased risk for bacterial urinary tract infections among women (53,54). Cervical Diaphragms In observational studies, diaphragm use has been demonstrated to protect against cervical gonorrhea, chlamydia, and trichomoniasis (34). Likewise, no difference by study arm in the rate of acquisition of chlamydia, gonorrhea, or herpes occurred (35,36). Providers should offer counseling about the option of emergency contraception if pregnancy is not desired. Ulipristal acetate is effective 5 days after unprotected sex, and levonorgestrel is most effective 3 days after unprotected sex but has some efficacy at 5 days. A 2019 Cochrane review summarized the efficacy, safety, and convenience of different emergency contraception methods (61).
