These are injury to the nerve 100mg viagra soft, injury to the blood vessels and injury to the internal organs within the thorax or abdomen which is more dreadful and may be fatal viagra soft 100 mg. It is of immense importance to exclude any other injury which may be associated with the bone or joint injury viagra soft 50mg. In this context one must remember that thoracic and abdominal injuries 50mg viagra soft, which tend to be overlooked 50 mg viagra soft, are more dangerous viagra soft 50 mg. When a pathological fracture is suspected 100 mg viagra soft, an attempt should be made to know the cause of the pathological fracture viagra soft 100mg. In infants , multiple fractures may be seen in cases of osteogenesis imperfecta (brittle bones) , which is characterized by dwarfism, broad skull, blue sclera, scoliosis, ligament laxity, otosclerosis (although deafness may not appear until adult life) and various deformities. In adults generalized fibrocystic disease (hyperparathyroidism) and multiple myeloma are the causes of multiple fractures. In case of secondary carcinoma a thorough search should be made to get at the primary focus either in the breast or thyroid or bronchus or kidney or prostate etc. At least two views antero-posterior and lateral should be taken to determine which bone has been fractured, the line of fracture and the type of displacement. The antero-posterior view shows sidewise displacement — external or internal whereas the lateral view reveals anterior or posterior displacement. The three points are mainly noted while reading X-ray plate: (i) Situation — which bone is broken and which part of it? A careful assessment of the line of fracture is very important to know the mechanism of the injury and the treatment to be instituted, (iii) Displacement. There may not be any shift as the fragments may be impacted or overlap each other, (b) Tilt — may be again forwards, backwards and sideways, (c) Twist (rotation) which may be in any direction. Sometimes X-ray picture should be taken from different positions to locate the sites of fracture which are difficult to be revealed in classical antero-posterior and the lateral views. These are oblique view in scaphoid fracture, stereoscopic views in fracture of the skull and pelvis, special axial radiograph in fracture of the calcaneum. In old fractures, one should look for the following points — (i) Signs of union — callus formation which appears in X-ray as early as on the tenth day after fracture. Consolidation and bone remodelling take quite a long time and one should not wait for these signs as the signs of union. In fact union occurs long before these signs develop and clinical test is better evidence of union than the radiological evidence. If there is no local tenderness at the site of fracture and attempt at abnormal movement between the fracture fragments fails to produce any pain or movement, it Figs. Note that there is hardly any evidence of fracture fracture has been united (clinically) though in the lateral view, but the anteroposterior view reveals X-ray shows a small gap between the fracture dislocation with considerable displacement. Note that the lower fragment is shifted upwards, slightly laterally with a variety of and tilted posteriorly. The increased blood flow and increased osteoid tissue formation, which are the processes of tumour-cell invasion, can be demonstrated by locally increased concentration of the gamma- emitting radioisotope. The increased radioactivity is displayed either as a number of counts on a scaler or pictorially as a "hot­ spot" on a scintiscan. Infrequently, in case of very anaplastic carcinoma, indolent tumours such as thyroid cancer or some cases of myeloma, there may be little or no "hot-spot" seen. Scanning is performed 1 to 4 hours after the intravenous injection of 5 to 10 mCi 99 ’ of Tcm-phosphate complex. The distal piece ‘D’ remains through the urine within first 4 hours after unaffected. This is a complication of fracture of the scaphoid injection and pelvic lesions are liable to be which so commonly takes place through its waist. It should be remembered that the simple radiograph shows no abnormality until more than 50% of bone mineral has been destroyed and obvious metastasis may be present even in the absence of X-ray changes. Bony metastasis from cancer of prostate may be present despite normal acid and alkaline phosphatase levels. Bone scan sometimes demonstrates "silent" metastasis which has produced fracture, which was initially thought to be simple. Arthroscopy is extremely helpful to detect joint injuries and particularly the semilunar cartilage (meniscus) injuries of the knee. Of the above symptoms and signs local bony tenderness, local bony irregularity, crepitus and X-ray are the most important points to be remembered. Dislocation is diagnosed by (i) the deformity, (ii) abnormal swelling near a joint, (iii) rigidity of the joint in passive movements and X-ray. Diagnosis is made (i) by presence of tenderness on the ligament particularly at its bony attachment, (ii) passive stretching of the ligament will cause excruciating pain, (iii) there is no local bony tenderness or local bony irregularity and (iv) X-ray shows no bony injury. Sometimes severe traction on the nerve during injury or during overzealous manipulation may lead to axonotmesis. Immediate nerve injuries which are seen with different bone and joint injuries are — (i) the spinal cord or cauda equina injury in fracture-dislocation of the spine, (ii) the axillary nerve in shoulder dislocation or fracture neck of the humerus, (iii) the radial nerve in fracture shaft of the humerus, (iv) ulnar, median and/or radial nerve in supracondylar fracture of the humerus, (v) sciatic nerve in posterior dislocation of the hip and subtrochanteric fracture of the femur and (vi) the common peroneal nerve in fracture of the neck of the fibula. The most common example is the "tardy ulnar palsy" in supracondylar fracture of the humerus which has been malunited with Cubitus Valgus deformity and in fracture of the medial epicondyle of the humerus where the ulnar nerve is involved in callus and gradual injury to the nerve by bony irregularity if anterior transposition of the ulnar nerve has not been performed. Sometimes they are pressed upon by the displaced fragment and very rarely they are completely divided. If the impairment is due to displaced fragment, prompt reduction of the fracture or dislocation should be called for. Sometimes the impairment of circulation is due to incorrect application of plaster of Paris and these cases should be treated by immediate removal of the plaster and bandages till the pulsation of the artery comes back. If these procedures fail to bring about improvement in circulation, there is a place for immediate arteriography with a view to possible excision and grafting. Vascular injury may lead to gangrene in severe cases and late ischaemic contracture of muscles in less severe cases. The torn fibres may become adherent to the intact fibres, fractured site or capsule of the neighbouring joint. This may lead to stiffness of the joint and may require lengthy rehabilitation after the fracture has been consolidated. So every attempt should be made to keep the muscles active when the fracture is kept immobilized. Tendinitis is a very rare complication of a fracture and occasionally affect the tibialis posterior tendon following fracture of the medial malleolus. Such examples are injury to the urinary bladder and urethra in fracture of the pelvis, rectum in the fracture of the sacrum, lung, liver or spleen in fracture of the ribs and the brain in fracture of the skull. It may give rise to osteomyelitis with formation of sequestrum and sometimes absorption of bone overwhelms leading to disappearance of some part of the bone. The most dreadful complications of a compound fracture are the gas gangrene and tetanus. The causes are (i) inadequate immobilization; (ii) internal fixation which always delays union as the haematoma between the fracture ends which acts as a scaffold for union is disturbed and because the periosteum is stripped off and (iii) intact fellow bone — when one bone of the forearm or the leg remains unbroken, the fractured bone always takes longer time for union. To know whether the fracture concerned is a case of delayed union or non-union, X-ray is very much essential. In non-union there will be presence of sclerosis at the bone ends and a gap between them. Causes of non-union are (i) infection; (ii) interposition of soft tissue either periosteum or muscle between the bone ends; (iii) inadequate blood supply e. The commonest deformity is angulation, besides this there may be overlapping with shortening and mal-rotation. The causes of mal-union are (i) fracture was not reduced properly; (ii) after reduction redisplacement occurs within the plaster, for this a check X-ray after a week is advisable in certain fractures anticipating redisplacement, e. Fracture-separation of an epiphysis does not lead to growth disturbance as the fracture occurs through the metaphyseal plate keeping the epiphyseal cartilage intact. Sites of mal-union are those where the bone is cancellous so union occurs as a rule, but mal-union complicates due to imperfect position of the bone ends. It complicates fracture when the blood supply of one fragment was derived from the other fragment when the bone was intact. So after fracture the blood supply of one fragment becomes completely deficient and undergoes avascular necrosis. This avascular necrosis will lead to non-union and osteoarthritis of the involved joint. The avascular bone shows greater density due to the fact that it does not share in the general osteoporosis due to deficient blood supply. The common sites of fracture which are liable to undergo this complication are the fracture neck of the femur, fracture of the scaphoid, fracture of the neck of the talus where the body undergoes avascular necrosis and dislocation of the lunate bone when the whole bone becomes necrosed. Though muscles can survive 6 to 8 hours ischaemia in contradistinction to the nerve tissue which can survive only a short period of ischaemia, yet the muscles cannot regenerate whereas the nerves can regenerate. This condition is commonly seen in the forearm following supracondylar fracture of the humerus which leads to occlusion of the brachial artery either by thrombosis or spasm or by the displaced lower end of the upper fragment. Nerves are also affected by ischaemia suggested by pain, weakness and numbness of the finger, but the nerves regenerate. In the early stage diagnosis is made by impaired circulation of hand and fingers, absence of the radial pulse and inability of the patient to extend the fingers fully with complaint of pain in full passive extension. In the established stage there will be obvious flexion deformity of the wrist and the fingers. Actually this condition develops when the haematoma under the stripped periosteum is invaded by osteoblasts and becomes ossified. This condition is commoner in children and young adults in whom the periosteum is loosely attached to the bone. This condition is more commonly seen in elbow after supra-condylar fracture or fracture of the head of the radius. It is also seen in some cases of fracture neck of the femur after operative fixation. More commonly periarticular adhesions occur from effusion into the ligaments and the capsules. Stiffness following fracture occurs mostly in the knee joint, the elbow joint, the wrist joint and the finger joint. In the shoulder joint the synovial fold on the inferior aspect of the joint is redundant and becomes adherent causing limitation of abduction movement. The commonest example is the stiffness of the knee following fracture of the shaft of the femur due to adhesion of the quadriceps muscles. In these cases quadriceps-plasty does a lot to increase the movement of the knee joint, (ii) Myositis ossificans. After union the joint surface becomes irregular and thus results in osteoarthritis. Mal-union may be the cause of osteoarthritis particularly in weight bearing joints where the direction of stress transmission becomes abnormal. Avascular necrosis is another potential factor which may lead to osteoarthritis, (v) Unreduced dislocation. Pain and stiffness of the fingers, hyperaesthesia and moistness of the ankle is diagnostic of this condition. In this chapter only those particular points of clinical examination are mentioned which will be required for a particular joint. With fracture of the clavicle the patient often supports the flexed elbow of the injured side with the other hand. Similarly with anterior dislocation of the shoulder the patient supports the flexed elbow of Fig. Flattening in case of dislocation of the shoulder is due to inward displacement of the upper end of the humerus. Here, of of the right shoulder due to subcoracoid course prominence of the greater tuberosity can be felt. If there is any undue prominence at the acromial or the sternal end of the clavicle, the case is probably nothing but dislocation of acromioclavicular or sternoclavicular joint respectively. In subcoracoid dislocation of the shoulder an abnormal swelling can be seen in the deltopectoral groove, there will be undue prominence of the acromion process with flattening of the shoulder. There will be drooping of the shoulder with undue lengthening of the arm in fracture neck of the scapida. In contrast to this, flip considerable swelling of the shoulder just below the | acromion process occurs in fracture neck of the H i, -—I ■ humerus, without any loss of roundness of the X A W shoulder. The surgeon places his hands on the sternal ends of the clavicles of the both sides. Firstly, he palpates the sternoclavicular joints and then proceeds laterally on both sides to palpate the entire length of the two clavicles simultaneously. The two joints on two sides of the clavicle are also examined in this process to exclude any dislocation there. The sternal end of the clavicle is mostly anteriorly displaced in sternoclavicular dislocation, Fig. It is better felt by the be remembered that the conoid and trapezoid ligaments hand in the axilla. The surgeon first palpates the acromion processes of both sides with the fingers of his two hands. He now gradually slides his fingers downwards to palpate the greater tuberosity of the humerus on both sides. Disappearance of the greater tuberosity of the humerus and loss of resistance here indicate dislocation of the shoulder. He now gradually slides his fingers downwards along the line of the humerus on both sides. Local bony tenderness and bony irregularity at the surgical neck of the humerus suggest fracture neck of the humerus. Similarly if the surgeon goes down to palpate the shaft of the humerus, he may exclude the fracture at this site by absence of local bony tenderness and bony irregularity. It must be remembered that in an unbroken bone the medial epicondyle shows the direction of the head of the humerus, whereas the lateral epicondyle shows the direction of the greater tuberosity. If this relation is disturbed, one must suspect the possibility of fracture either at the neck of humerus or at the shaft.

Nevertheless viagra soft 100 mg, a trial of therapy is often necessary to rule out the nutritional neuropathies 100 mg viagra soft. Lumbar puncture 50 mg viagra soft, as already mentioned viagra soft 100mg, is useful in diagnosing Guillain–Barré syndrome 50mg viagra soft. These findings would suggest a diagnosis of cerebral vascular disease viagra soft 50mg, a space-occupying lesion of the brain 100mg viagra soft, migraine viagra soft 50 mg, or multiple sclerosis . Pain in the involved extremity , particularly radicular pain, should suggest a herniated cervical disk, spinal cord tumor, or cervical spondylosis. However, many other conditions, such as brachial plexus neuropathy, thoracic outlet syndrome, a cervical rib, Pancoast’s tumor, Raynaud’s disease, and sympathetic dystrophy, should also be considered. Finally, the various entrapment syndromes should be considered, such as carpal tunnel syndrome and ulnar nerve entrapment at the elbow. If the radial pulse diminishes in certain positions of the neck and shoulders, a thoracic outlet syndrome or cervical rib should be considered. A positive Tinel’s sign at the wrist would suggest a carpal tunnel syndrome and can be confirmed by a positive Phalen’s test. The ulnar nerve may also be entrapped in Guyon’s canal and the median nerve may be trapped at the elbow in a pronator syndrome. The presence of a positive cervical compression test or a positive Spurling’s test would suggest cervical spondylosis and herniated cervical disk. The presence of hyperactive reflexes in the upper or lower extremity would suggest a spinal cord tumor, multiple sclerosis, degenerative disease of the spinal cord, such as syringomyelia or amyotrophic lateral sclerosis, anterior spinal artery occlusion, and cervical spondylosis. The presence of normal or hypoactive reflexes in the involved extremity should prompt consideration of peripheral neuropathy, pernicious anemia, and brachial plexus neuropathy. If these are negative, the next logical step is to consult a neurologist or neurosurgeon. If tabes dorsalis is suspected, a blood or spinal fluid fluorescent Treponema pallidum antibody test may be done. A therapeutic trial of vitamin B6 or corticosteroids may diagnose carpal tunnel syndrome if a neurologist is not available. If the pathologic reflexes come and go, transient ischemic attacks, multiple sclerosis, migraine, epilepsy, and hypoglycemia should be considered in the differential diagnosis. Unilateral pathologic reflexes should signify either a brain tumor or vascular lesion. Bilateral pathologic reflexes should suggest an inflammatory or degenerative disease. However, multiple sclerosis may present with either unilateral or bilateral pathologic reflexes. Vascular lesions in the basilar circulation may also present with bilateral pathologic reflexes. The presence of facial palsy or other cranial nerve signs should make one look for a lesion in the brain or brain stem. The presence of headache or papilledema should prompt the investigation for a space-occupying lesion of the brain or brain stem. These findings would suggest a cerebral vascular accident such as cerebral hemorrhage or embolism. The findings of bilateral pathologic reflexes or unilateral pathologic reflexes with a normal sensory exam and no cranial nerve signs would suggest amyotrophic lateral sclerosis or primary lateral sclerosis. However, it is wise to get a neurology consultation before undertaking these expensive tests. If vascular disease is suspected, carotid scans to rule out carotid stenosis or plaque and a search for an embolic source using echocardiography and blood culture should be done. In fact, if a cerebral hemorrhage has been ruled out and there is no significant hypertension, a four-vessel cerebral angiographic study should probably be done. Serum protein electrophoresis and immunoelectrophoresis all may be necessary in the workup. The history of menorrhagia or metrorrhagia should suggest ectopic pregnancy, endometriosis, and threatened abortion, as well as retained secundinae. A positive pregnancy test is the key to a diagnosis of ectopic pregnancy when there is abdominal pain along with the abdominal mass. If there is a vaginal discharge, a smear and culture of the material should be made. If a distended bladder is suspected, catheterization for residual urine must be done. The gynecologist may do a laparoscopy, a culdocentesis, and, ultimately, an exploratory laparotomy. There is a history of heavy periods and on examination, she had an enlarged asymmetrical uterus. The pregnancy test is negative so, you suspect either uterine fibroids or endometriosis. The presence of a pelvic mass would suggest salpingo-oophoritis, ectopic pregnancy, endometriosis, uterine fibroid, or an ovarian tumor that is twisting on its pedicle. Be sure to do a rectovaginal examination as there may be a mass or fluid in the cul-de- sac. The history of metrorrhagia or menorrhagia would suggest ectopic pregnancy, threatened abortion, retained secundinae, uterine fibroids, and endometriosis. The presence of a positive pregnancy test would suggest an ectopic pregnancy or threatened abortion. If the pain is related to the menstrual cycle, mittelschmerz should be considered. The next step would logically be a pelvic or transvaginal ultrasound, but it is wise to consult a gynecologist before ordering expensive tests. The gynecologist may proceed with laparoscopy, culdocentesis, and, 486 ultimately, an exploratory laparotomy. If there is fever, a trial of antibiotics may be appropriate even if the workup is negative. The presence of a painful penile sore suggests chancroid, herpes simplex, herpes zoster, and balanitis. On the contrary, a painless penile sore should suggest chancre, lymphogranuloma venereum, epithelioma, granuloma inguinale, and papilloma. If there is inguinal adenopathy, lymphogranuloma venereum, epithelioma, and chancre should be suspected. A Tzanck test, serologic test, and viral isolation will help diagnose herpes zoster and herpes simplex. These findings suggest prostatitis, urethritis, cystitis, bladder calculus, bladder carcinoma, vaginitis, and abscesses of Cowper’s glands. These findings suggest hemorrhoids, perirectal abscess, anal fissure, anal ulcer, rectal carcinoma, and condylomata lata. Pelvic ultrasound will be helpful in diagnosing endometriosis, ectopic pregnancy, and pelvic appendicitis. The presence of a periorbital or facial rash should suggest contact dermatitis, angioneurotic edema, trichinosis, and herpes zoster. The presence of generalized edema suggests myxedema, cirrhosis, acute and chronic glomerulonephritis, congestive heart failure, and other disorders. The presence of fever suggests acute sinusitis, cavernous sinus thrombosis, orbital cellulitis, meningitis, and neurosyphilis. If there is fever, a nose and throat culture and blood culture should be done and antibiotics begun without delay. Trichinosis can be diagnosed by the skin test, serologic studies, or a muscle biopsy. In infants with pyloric obstruction, the vomiting is projectile, and the severe dehydration that follows, along with the right upper quadrant mass (a hypertrophied pylorus), helps to make the diagnosis. In adults with pyloric obstruction, the enlarged stomach with peristaltic waves going downward from left to right and a succussion splash are useful diagnostic signs. A flat plate of the abdomen (demonstrating the dilated stomach) and significant electrolyte alteration of metabolic alkalosis and potassium depletion will help confirm the diagnosis, but an exploratory laparotomy will remove all doubts. The peristalsis is transverse in small intestinal obstruction and vertical in large intestinal obstruction. Quinine, cocaine, atropine, and Apresoline are just a few of the drugs that may cause photophobia. Almost any condition of the eye may cause photophobia, including conjunctivitis, blepharitis, keratitis, iritis, corneal ulcers, and retinitis. Without fever or with only a low-grade fever, the presence of nuchal rigidity should suggest subarachnoid hemorrhage. If there is fever without nuchal rigidity, the workup can proceed as outlined on page 198. The fistula results from ruptured diverticulitis, ruptured appendix, or a neoplasm that forms a pelvic abscess that gradually eats its way into the bladder. Looking through her chart, you find laboratory results that show an increase in hemoglobin and hematocrit. Following the algorithm, you check for clinical signs of dehydration, and there are none. Her oxygen saturation is 96%, so pulmonary fibrosis or emphysema is an unlikely cause. You suspect polycythemia vera, but note that she is obese and has purple abdominal striae. If the plasma volume is decreased, think of dehydration, diuretic use, or other factors. Decreased oxygen saturation would suggest emphysema, pulmonary fibrosis, or cardiovascular disorder. An increase in the blood erythropoietin would suggest an erythropoietin-secreting tumor such as renal carcinoma or pheochromocytoma. A normal or decreased erythropoietin would point to polycythemia vera, heavy cigarette smoking, or methemoglobinemia. A hematology consult would be wise before undertaking any of the more expensive studies. The presence of these symptoms would suggest diabetes mellitus and hyperthyroidism. The presence of massive polyuria suggests diabetes insipidus or psychogenic polydipsia. The presence of mild polyuria should suggest chronic renal failure, renal tubular acidosis, hyperparathyroidism, and febrile illnesses. Also, a 24-hour urine collection for calcium may be done to help diagnose this condition. Microscopic examination of the urinary sediment will help diagnose renal disease, as will renal biopsies. The Hickey–Hare test and monitoring intake and output before and after vasopressin (Pitressin) will be useful in differentiating pituitary diabetes insipidus from nephrogenic diabetes insipidus. An endocrinologist should be consulted before ordering these expensive diagnostic tests. The presence of these symptoms would suggest diabetes mellitus or hyperthyroidism. This symptom would indicate that the patient has an insulinoma, Cushing’s disease, or idiopathic obesity. These symptoms would signal that the polyphagia is related to bulimia, hysteria, or other psychic disorder. If an insulinoma is suspected, plasma insulin or C-peptide levels may be done, or the patient may be hospitalized for a 72-hour fast with frequent blood sugar determinations. If hyperthyroidism, diabetes mellitus, insulinoma, and intestinal disorders have been ruled out, a referral to a psychiatrist would be indicated. Massive polyuria is usually because of pituitary or nephrogenic diabetes insipidus and psychogenic polydipsia. The presence of polyphagia and polydipsia suggests the possibility of diabetes mellitus and hyperthyroidism. The presence of a mild polyuria suggests chronic nephritis, renal tubular acidosis, hyperparathyroidism, Fanconi’s syndrome, and mild diabetes mellitus. The presence of glycosuria suggests diabetes mellitus, hyperthyroidism, and Fanconi’s syndrome. If renal disease is suspected, the urinary sediment should be examined microscopically and renal biopsy may be necessary. An endocrinologist and nephrologist should be consulted before undertaking expensive diagnostic tests. A soft popliteal swelling may be an abscess, varicose vein, Baker’s cyst, popliteal aneurysm, or swollen bursa. A firm popliteal swelling may be an osteosarcoma, periostitis, giant cell tumor, exostoses, lymphadenitis, lipoma, or fibroma. Masses that are connected to the bone are more likely exostoses, osteosarcomas, periostitis, or giant cell tumors. However, it is more cost-effective to seek an orthopedic consultation before ordering these tests or undertaking aspiration of the swelling. Children may take birth control pills early in life, and young boys may want to take anabolic steroids to increase their muscular mass. These findings would suggest a brain tumor, and a pinealoma is one that should be excluded. The presence of an adnexal mass would suggest a granulosa cell tumor or arrhenoblastoma.

Furthermore, although maximal clench is dimin- bc), commonly regarded as one of the greatest of all classical Greek ished,17 no detrimental efect on chewing has been observed, as the sculptors. In simple algebraic terms, the golden section is the only masseter and pterygoid muscles remain the principle contributors to point dividing a line into two parts where the smaller segment in mastication. As such, the superior portion of the muscle is frmly adherent to the underlying bone and devoid of interposing fascia. Te periosteum and deep fascia of the forehead (galea aponeuro- (a) (b) tica) as they traverse the upper face under the frontalis muscle can- not continue under the temporalis muscle and as such lie over the muscle as the deep and superfcial temporal fascia respectively. This anatomical oddity, of a deep fascia lying on the surface of the mus- cle which bears its name, provides a resistant plane that is apprecia- bly felt when penetrating the region with a needle. Overlying this fascia in the posterior leaves of the superfcial temporal fascia are the superfcial temporal vessels (arteries and veins) and specifcally the frontal ramus of the superfcial temporal artery. Located in the depth of the muscle are the anterior and posterior deep temporal arteries (branches of the internal maxillary artery, second division), the middle temporal artery (connecting the deep and superfcial arterial system), and the prominent middle temporal vein approxi- mately 2 cm above the zygomatic arch. Deposition of botulinum toxin deep to the fascial layer is mandatory to access the bulky deep muscle as outlined above, and will require a 30-gauge needle of minimum ½ inch length. Prudent technique would require aspira- (c) tion before injection of toxin into the temporal muscle to mini- mize the possibility of intravascular washout limiting the clinical result. Post-injection pressure for several minutes, regardless of the appearance of blood through the puncture site, will diminish the possibility of delayed unsightly bruising. T e Beautiful Glabella and Botulinum Toxin Subtle diferences in glabellar appearance have a profound efect on beauty and youthfulness. Aging skin changes and actinic expo- sure lead to the appearance of lines, creases, and dyschromias com- pounded with tissue atrophy and volume loss. Bone remodeling leads to an increase in glabellar height and width, which can ofen be evi- denced by a paradoxical elevation of the medial brow in the elderly (Figure 8. This is to be distinguished from an elevated eyebrow resulting from increased frontalis activity as compensation for an upper eyelid partial levator dehiscence. Simply stated, com- cial gliding muscles, the frontalis (elevator) and the procerus (depres- plete loss of the tethering efect of medial corrugator pull, in combina- sor); and two deep brow depressor muscles, the paired corrugator tion with the unopposed oblique pull of the frontalis muscle, can lead and depressor supercilii.

Once these patients and depressors is somewhat stratifed as the frontalis blends superf- are identifed, the addition of a small amount of toxin into the upper cially with the deeper depressors. Varying the height and depth of toxin deposition according to the muscle action being targeted can alter the resting posi- tion of the medial brow. Phi harmony in the upper face dictates that the medial brows begin in a vertical line above the medial canthii at a 1. This technique is indicated when medial eyebrow position is too high and superior medial orbital hollowing is present to accom- modate the potentially redundant skin that may occur as a result of treatment.

Originally a Western tenet of beauty, large prominent to approach Phi proportions (Figure 8. Contraction of the orbicularis oculi is therefore more sphincteric than vertical, drawing the eyebrow inferomedially toward the nose. This explains why chemodenervation of the lateral vertical fbers very ofen results in an upward and lateral excursion of the tail of the brow. Te orbicularis oculi muscle is much more expansive than appears on the surface, extending superiorly and inferiorly beyond the orbital rim in an “aviator glasses” shape, and occasionally laterally as far as the temporal hairline. This sometimes necessitates a second row of toxin injections more lateral from the lateral orbital rim to have the desired efect. Te nose lengthens and the tip droops, with retrac- tion of the columella, and alar base widening with superior excursion. Te periorbital complex typically shows signs of aging in the third decade of life with skin color and consistency changes. This early chronological senescence is not unexpected as the thin skin of the periorbital region is exposed to the stress of blinking an average of 1200 times per hour. Additionally, expansion of the inferolateral (middle age) and superomedial (advanced age) orbital rims, results in a volumetric increase of the bony orbit relative to its contents.

When instilled onto the ocular surface, they have adrenergic secondary efects on Muller’s muscle and cause temporary contraction and upper eyelid elevation. Teir utility has become common in some forms of “small eyes” including botulinum toxin-induced lid ptosis. Similarly, upper eyelid elevation with the creation of “round eyes” can be achieved by reducing the efective force of the upper eyelid depressors (orbicularis oculi) through pre- cise chemodenervation. Surgical Anatomy Pearls: Tere has also been confusion as to where the most efective placement is and what that dose should be. Again, understanding the details of the periorbital anatomy will shed light on this. Te fbers of the orbicularis muscle at the lateral periorbita are more vertical hence contraction will cause the formation of “crow’s feet” and lateral brow depression.

In this case 50 mg viagra soft, there will be anaesthesia of the whole upper limb except the upper part of the arm which is supplied by C3 100 mg viagra soft, 4 & 5 and by the intercostobrachial nerve . There will be also complete paralysis of the arm and scapular muscles , occasionally the long thoracic nerve supplying the serratus anterior or the nerve supplying the rhomboids may escape. It may affect new bom babies during difficult confinements or adult by a fall of weight on the shoulder. The muscles affected are biceps, brachialis, brachioradialis, supinator and deltoid. But if the 6th nerve is also affected, there will be an area of anaesthesia over the outerside of the arm and upper part of the outerside of the forearm. As the innervation of the hand is intact, functional improvement may be obtained conservatively by maintaining full range of passive movement of the limb to prevent contracture and the anaesthetic skin is protected to avoid pressure sores etc. Function of the limb can be best restored by arthrodesis of the shoulder and elbow joints. One may venture transplantation of muscles from the pectoral groups to the humerus. This type of lesion can occur when a falling person clutching at an object and hyper-abducting his arm or failing to obtain a foot-hold on a passing bus. The result is paralysis( of the intrinsic muscles of the hand (with claw-hand and features of combined median and ulnar nerves palsy) with anaesthesia of the inner one and half fingers. Very occasionally spasticity of the lower limb may be noticed associated with this condition, which is a result of damage to the pyramidal tract from haemorrhage following avulsion of the nerve roots. Recovery of function may occur when the lesion is due to stretching-(neurapraxia). But if the nerves have been ruptured, maldistribution of down-growing fibres will definitely lead to considerable reduction in functional efficiency. It is injured — (i) Due to fracture of the neck of the humerus; (ii) Dislocation of the head of the humerus; (iii) By a direct blow or (iv) Intramuscular injections. This nerve supplies the deltoid muscle and a portion of the skin on the lateral aspect of the arm which overlies the deltoid muscle. The patient also feels difficulty in raising the arm above right angle from a position in front of the body due to inability of rotation of scapula on the chest wall owing to paralysis of the serratus anterior muscle. Its main branch, the posterior interosseous nerve, which is concerned with supplying the extensor muscles of the wrist and fingers, may be injured at the elbow. Paresis of this nerve has occurred only after using 4 hours with this type of crutch without handgrips. Motor paralysis — (i) Triceps muscle — which causes inability to extend the forearm against resistance. However the patient can extend the interphalangeal joints with the unaffected interossei muscles (supplied by the ulnar nerve) and lumbricals (supplied by the median and ulnar nerves). So when the radial nerve is injured the patient will not be able to extend the metacarpophalangeal joint, but will be able to extend the interphalangeal joints. However paralysis of the brachioradialis can be tested by asking the patient to flex the elbow joint keeping the forearm in midprone position against resistance. This becomes difficult and the muscle will not stand out in case of brachioradialis paralysis. There will be also anaesthesia of the dorsum of the thumb and lateral three fingers upto the proximal interphalangeal joint owing to overlap by the ulnar nerve and median nerve. This is due to the fact that the branches supplying all the 3 heads of the triceps and the anconeus arise from the radial nerve before it reaches the radial groove. There is also anaesthesia on the back of the fingers upto the proximal interphalangeal joints except in the thumb where it reaches upto the nail, as both posterior cutaneous nerve of the arm and posterior cutaneous nerve of the forearm arise from the radial nerve before it reaches the radial groove. As the flexor carpi ulnaris remains active, the hand will be deviated towards the ulnar side particularly when the wrist is flexed. Flexion of the index finger will be fully affected though the flexion of other fingers may be carried out with the help of the medial part of the flexor digitorum profundus which is supplied by the ulnar nerve. Flexion of the terminal phalanx of the thumb becomes impossible due to paralysis of the flexor pollicis longus and the patient will fail to flex the terminal phalanx of the thumb against resistance while the proximal phalanx is being steadied by the clinician. Paralysis of the muscles of the thenar eminence is a characteristic feature of median nerve injury. The abductor pollicis brevis, opponens pollicis and flexor pollicis brevis, which constitute the thenar eminence are paralysed. Even the first dorsal interosseous and the two lateral lumbricals are also supplied by this nerve. While supply to the interosseous and lumbrical muscles are not very significant, yet paralysis of abductor pollicis brevis will be evident by the pen test, in which the patient is asked to touch a pen, which is kept at a slight higher level than the palm of the hand, with the tip of the thumb. Paralysis of opponens pollicis will be evident by the failure of the patient to touch the tips of the other fingers with the tip of the thumb. As the pronators of the forearm become paralysed, pronation of the forearm becomes feeble which will be particularly evident if the patient is asked to pronate his semiflexed forearm. Pronation of forearm becomes almost nil after midprone position, upto which brachioradialis can pronate the forearm. This anaesthesia will be extended over the tip of these fingers upto the middle of the middle phalanges on the posterior surface of these fingers and upto the nail bed of the thumb. These areas of sensory loss of course will be gradually reduced due to overlapping from adjacent nerves. It must be remembered that ulnar nerve passes superficial to the flexor retinaculum and hence is more often involved in cut injuries of the wrist. There will be slight deviation to the radial side of the hand when the wrist is flexed. Moreover the tendon of flexor carpi ulnaris just above its insertion into the pisiform bone will become impalpable when it is paralysed. There will be weakness of flexion of the little and ring fingers particularly at the distal interphalangeal joints. Paralysis of the muscles of the hypothenar eminence also occur due to injury to the ulnar nerve. This nerve supplies the abductor digiti minimi, flexor digiti minimi, opponens digiti minimi, both the heads of the adductor pollicis and sometimes a small twig to the flexor pollicis brevis. It also supplies all the interossei probably with the exception of first dorsal interosseous and to the third and fourth lumbrical muscles. The dorsal interossei are concerned with abduction of the fingers, while palmar interossei adduct the fingers. In case of ulnar paralysis a typical claw hand or Main en griffe will be noticed particularly in late cases. In this condition there is hyperextension of the metacarpophalangeal joints and flexion of the proximal and distal interphalangeal joints. In ulnar nerve paralysis though the first and second lumbricals are exempted yet this deformity can be obviously noticed in ring and little fingers. As the dorsal interossei are concerned with abduction of the fingers, if the patient is asked to abduct the fingers against resistance, he will be unable to do so in case of ulnar nerve palsy. A card is placed between the two fingers and asked to grip the card with the two fingers by adducting the fingers and the clinician tries to pull the card. The latter can assess the strength of the palmar interossei by the force of pull required for the purpose. If a patient with ulnar nerve injury is asked to hold a book between his hand and the thumb with the thumb straight he will fail to do so and he will try to hold the book by flexing the distal interphalangeal joint of the thumb with the help of flexor pollicis longus. As interossei alongwith lumbricals through extensor expansions are also concerned with extension of the proximal and distal interphalangeal joints, the strength of the interossei can be tested by asking the patient to straighten the finger against resistance while the clinician steadies the proximal phalanx of that finger. The lateral popliteal portion is affected nine times more commonly than the medial popliteal portion as the latter passes down on the inner and deep aspects of the sciatic nerve. The lower part of the lateral part of the leg is supplied by the superficial peroneal (musculocutaneous) nerve. The medial border of the foot is supplied by the saphenous nerve, whereas the lateral border of the foot is supplied by the sural nerve so these portions are exempted. Using these tests it is possible to distinguish between a nerve injury in which axons have not degenerated distal to the lesion (neuropraxia) and one in which Wallerian degeneration has occurred (axonotmesis or neurotmesis). Electromyography helps to read the electrical activity of a muscle during rest and activity. During weak contraction it records single action potential and in powerful contraction an interference pattern is observed due to more action potentials. Denervated muscle shows denervation potentials which appear within 1 to 2 weeks after injury. It also indicates whether any nerve injury is complete or incomplete and whether regeneration is taking place or not. Even the level of nerve injury can be determined by showing the changes of denervation of the muscles supplied by the nerve distal to the nerve injury. The duration and strength of the current used to excite a muscle is plotted in a graph as the strength duration curve. A normal muscle responds to stimuli varying in duration from 300 milliseconds to 1 millisecond without any increase in strength of the current. If the duration of current is decreased, the strength of current is to be increased to produce contraction. A totally denerved muscle needs either more strength of current or for a longer duration. Presently this investigation is mainly used to know the damaged of the cervical nerve roots after brachial plexus injury. Usually the pain starts following incomplete injury or division of the nerve, though occasionally such pain may not appear before 2 or 3 months. Accumulation of this substance causes vasodilatation and the part becomes red, sweats profusely and becomes increasingly painful. According to the site, cervico-thoracic or lumbar sympathectomy may be required, which are discussed below. These are mapped out by applying sweat-sensitive starch and iodine dusting on the axilla. When the hands are too much sweating, cervico-thoracic sympathectomy should be the treatment of choice. When the feet are sweating excessively with sodden and offensive feet, lumbar sympathectomy is justified. The arteries which have got smooth muscles in their walls, will be released of their spasms due to sympathectomy. These arteries are generally medium sized, small arteries, arterioles and arteriovenous communications. The limb will be warm, pain will be less and the ulcers may show signs of regression. The pathological conditions under this category, which are benefited by sympathectomy, are as follows : (a) Atherosclerosis. Some vascular surgeons suspect whether sympathectomy really increases the deep collateral circulation or simply increases vascularisation of the superficial tissue and skin. But one thing is certain, that if amputation is at all required, previous sympathectomy will definitely limit its extent. The symptomatic relief is rather temporary and almost always fails to yield permanent relief. By sympathectomy, one can only delay the progress of the disease, but cannot have a long term good effect. When sweating is sufficiently profuse to make one psychotic, this operation should always be called for. In the2 7 sympathetic trunk these fibres pass up to synapse about cells, situated mainly in the cervico- thoracic ganglia, from where post-ganglionic fibres pass to the brachial plexus, mainly the lower trunk. Most of the vaso-constrictor fibres supplying the arteries of the upper limb, emerge from the spinal cord in the ventral roots of 2nd and 3rd thoracic nerves. So these arteries can be denervated surgically by cutting the sympathetic trunk below the 3rd thoracic ganglion, severing the rami communicantes connected with the 2nd and 3rd thoracic ganglia and dividing the sympathetic trunk proximally just above the lower half of the cervico-thoracic ganglion (Tl part) distal to the attachment of the white ramus. Sympathetic fibres to the lower limb emerge from the spinal cord between T and L They9 r pass to the sympathetic trunk and then pass downwards, synapsing with the cells in lower lumbar and sacral ganglia from where post-ganglionic fibres arise and innervate the vessels of the lower limb. So removal of the lumbar sympathetic trunk just below the first ganglion proximally and below the 3rd ganglion distally will denervate the blood vessels of the lower limb. This denervation is essentially pre-ganglionic and particularly of those vessels below the knee level, as the cells lie in the lower lumbar and sacral sympathetic ganglia. This may be the main reason why sympathetic denervation of the vessels of the lower limb is more effective than that of the upper limb, which is a mixed pre- and post-ganglionic denervation. For axillary hyperhidrosis, the upper four or five thoracic ganglia should be removed (so axillary approach is more convenient). Cervico-thoracic sympathectomy can be performed by one of the three following approaches:— A. The head is rotated to the opposite side and the hand of the corresponding side is pulled downwards. An incision is made about 1/2 inch above the clavicle starting from the lateral border of the sternal head of the stemomastoid muscle to the medial border of the trapezius. After incising the skin, superficial fascia, platysma and investing layer of the deep cervical fascia, the clavicular head of the stemomastoid is divided and the inferior belly of omohyoid is retracted upwards to expose the scalenus anterior and the phrenic nerve. The phrenic nerve is safeguarded and the scalenus anterior is divided at its insertion to the first rib. The pleura is pushed downwards and laterally to expose the sympathetic trunk and the corresponding posterior ends of the ribs.
