Pain on moving the ear suggests otitis externa buy zovirax without prescription antiviral para que sirve, foreign body generic zovirax 200 mg with visa hiv infection from blood test, impacted wax order 200 mg zovirax mastercard hiv infection eye splash, or keratosis obturans order generic zovirax online hiv infection trends. Hearing loss with an abnormal drum would suggest serous or bacterial otitis media. Dental caries, dental abscesses, impacted teeth, tonsillitis, and temporomandibular joint syndrome may refer pain to the ear. If the drum is obscured by wax, gentle lavage after using Debrox will usually clear the canal. X-ray of the mastoids and petrous bones should be done if the exudate is believed to be from a deeper source. If there is hearing loss, an audiogram needs to be done and a tympanogram will be useful in diagnosing serous otitis media. A trial of carbamazepine (Tegretol) or phenytoin (Dilantin) may be useful in diagnosing glossopharyngeal neuralgia or tic douloureux. In children, a trial of antibiotics may be worthwhile especially if the drum is not visualized. Referral to an ear, nose, and throat specialist or neurologist should be considered before ordering expensive diagnostic tests. Edema that pits on pressure is more likely to be because of heart, liver, or kidney disease. Edema that does not pit on pressure is more likely because of myxedema or lymphedema. If there is hepatomegaly, one should consider liver disease such as cirrhosis or cardiac disease. If there is ascites along with hepatomegaly, cirrhosis of the liver is the most likely cause of the edema. If there is no ascites along with the hepatomegaly, then congestive heart failure should be considered. Jugular vein distention certainly would be most suggestive of congestive heart failure, but other causes of jugular vein distention include superior vena cava syndrome because of a mediastinal mass such as carcinoma of the lung and constrictive pericarditis. Right heart failure secondary to pulmonary emphysema and fibrosis can also cause jugular vein distention. If there is abnormal urinary sediment, consider nephritis, whether it might be because of chronic glomerulonephritis or whether it is secondary to diabetes mellitus or a collagen disease. Among the drugs that should be considered are corticosteroids, progesterone, estrogen, anti-inflammatory drugs such as naproxen (Naprosyn) and ibuprofen (Motrin), antihypertensive drugs such as methyldopa (Aldomet) and clonidine hydrochloride, calcium channel blockers, beta-adrenergic blockers, and antidepressants. The urinalysis is very important both for routine studies and also to examine the urinary sediment for diseases such as chronic glomerulonephritis and collagen disease. If there is significant loss 213 of protein in the urine, one should be considering nephrosis. When there is a strong suspicion of congestive heart failure, echocardiography or radionuclide-gated blood pool scintigraphy should be done to determine the left ventricular ejection fraction. Acute edema, if it is localized, should always bring to mind a deep vein thrombophlebitis. It also should bring to mind acute lymphangitis, particularly if there is erythema in the area. Finally, it should also make one think of trauma or a focal infection such as cellulitis. Chronic localized edema, however, is more likely related to varicose veins or lymphedema. If the edema pits, it is more likely related to inflammation or venous incompetence. If it is nonpitting, it is more likely because of obstruction of the lymphatics, that is, lymphedema. Erythema and focal tenderness would suggest cellulitis, lymphangitis, thrombophlebitis, angioneurotic edema, insect bite, or snake bite. Focal tenderness alone with pitting edema and no significant erythema or rash would suggest a deep vein thrombophlebitis. When there is no erythema or tenderness in a case of pitting edema of a localized nature, one should consider varicose veins or, in the lower extremities, a popliteal cyst that might be obstructing the veins on a chronic basis. A positive Homans’ sign should always be looked for because this would suggest a deep vein thrombophlebitis. D-dimer testing is also a sensitive indicator of active deep vein thrombophlebitis and the need for anticoagulants. Lymphangiography will be helpful in the diagnosis of carcinomatosis or lymphedema from other causes. A thyroid profile will diagnose cases of pretibial myxedema 215 because of thyrotoxicosis. Table 08: Pedal Edema The reader needs to keep in mind that exceptions to these findings do occur. Horner’s syndrome includes enophthalmos, partial ptosis, constricted pupil, absence of sweating, and the presence of blushing on the side of the sympathetic paralysis. Prolonged endophthalmitis may cause unilateral enophthalmos because of shrinkage of the eyeball. Bilateral enophthalmos may be because of starvation or cachexia (in which case the cause should be obvious) or congenital. Frequent bed- wetting should signify pathology in the urogenital tract or endocrine system. There are many causes of enuresis that can be found on a simple examination, such as phimosis, balanitis, meatal stricture, vulvitis, or intestinal worms. Urinalysis alone is usually not adequate, and a urine culture should be done to rule out cystitis and pyelonephritis. Sugar in the urine may indicate diabetes mellitus, but it may also indicate Fanconi’s syndrome. Polyuria might indicate diabetes insipidus, diabetes mellitus, hyperthyroidism, and hypoparathyroidism. Here one would be looking for cerebral palsy and congenital anomalies of the spinal cord. Finally, if the neurologic examination, urogenital examination, and urinalysis are normal, perhaps the patient has a simple neurosis or situational maladjustment. If the neurologic examination is abnormal, referral to a neurologic specialist would be in order. If all the studies and examinations are within normal limits, a referral to a psychiatrist or psychologist may be in order. However, the child may have simple enuresis, in which case all that is required is to reassure the parents that the child will grow out of it by puberty. Enuresis that develops after a substantial period of dryness may indicate sexual abuse. If it is bilateral, it is most likely because of emotional weeping or because of the effects of drugs such as bromides, arsenic, and mercury.
Disposition of the middle palmar cheap 800 mg zovirax otc hiv infection by race, thenar and dorsal spaces are shown with If the condition remains their important relations buy discount zovirax 800mg on-line hiv gum infection. Drainage is provided by making an incision along the distal palmar crease at its ulnar side buy 200mg zovirax mastercard antiviral lip cream. The palmar fascia is carefully divided and a sinus forcep is introduced and opened to drain the pus liberally 200 mg zovirax with mastercard hiv infection through blood transfusion. It is often advantageous to divide the palmar fascia longitudinally to avoid damage to digital vessels and nerves. The skin edges as well as the edges of the palmar fascia are trimmed for free drainage. If the pus has tracked down into the lumbrical canals, it may be drained by incising the web space as mentioned in the drainage of web space infection. Flexion of the metacarpophalangeal joint of the thumb or the index finger will be painful. Drainage is effected by an incision in the line of this web between the thumb and the index finger. A sinus forceps is pushed into this wound in front of the adductor pollicis muscle and the pus will come out automatically. Intensive antibiotic therapy should be started immediately and care must be taken to exclude possibilities of infection at other spaces, since this will also lead to swelling of the dorsum of the hand. Infection of these spaces generally subside automatically with antibiotic therapy and drainage is not required very often. Whenever it is suspected that the pus has been localized at this space, drainage is obtained by a longitudinal incision on the most prominent part of the swelling. Longitudinal incision will save the blood vessels, tendons and nerves at this region, but transverse incision is of more cosmetic value, though the risk of injury to nerves and vessels is more in this incision. Within a few hours the hand becomes swollen and painful with severe constitutional disturbances like high fever. As the superficial lymphatic vessels from the palmar aspect courses to the dorsum of the hand, oedema is mostly seen on the back of the hand. When infection enters into the lateral half of the hand involving the thumb and index finger, the axillary nodes are first involved. When infection affects the medial half of the hand, the epitrochlear group of lymph nodes become enlarged and tender. This is primarily treated by antibiotics and operative drainage is only required when there is localized abscess formation. A bloodless field is preferred as it offers better view to the position of nerves and tendon sheaths and damages caused to them. First change of dressing should be done after 24 hours of operation and thereafter on alternate days. This deformity usually consists of (i) relatively short radius, (ii) resultant radial deviation of the hand, (iii) with prominence of the head of the ulna and (iv) with sometimes contracture of the little finger. Congenital contracture of the little finger — is commonly seen during early childhood. The fascia is thickened to form nodules and it contracts so that eventually the affected fingers are drawn into flexion. That it is often bilateral and may involve even the feet speaks against traumatic origin. Histologically such plaque contains tom collagen fibres and altered blood pigments. As the palmar fascia gradually thickens and shrinks, its distal prolongations pull the fingers into flexion. The distal prolongations of the palmar fascia are attached to the sides of the proximal and middle phalanx. From the palmar fascia there are some superficial attachments to the skin of the palm, which also shrink to pucker the palmar skin. In long standing cases, nodules can be palpated in the palmar fascia and gradually permanent changes take place in the metacarpophalangeal and proximal interphalangeal joints, so that the fingers cannot be made straight. The nodule gradually enlarges and spreads strands of contracting fascia which become prominent. The contracted strands can be felt running from the nodule to the base of the ring and little fingers. The metacarpo-phalangeal joint and the proximal interphalangeal joints are flexed, as the palmar fascia extends distally to be attached to both sides of the proximal and middle phalanges. The distal interphalangeal joint is never flexed, on the contrary may be hyperextended. Flexion deformity of the fingers is not lessened by flexion of the wrist joint (cf. There may be thickening of the subcutaneous tissue on the dorsum of the proximal interphalangeal joints of the affected fingers. The following operations may be performed according to the severity of the case :— Fasciotomy. The skin is carefully separated from the fascia and the contracted bands are divided. This procedure is repeated in other places of the fascia using separate points of entry till all the contracted bands are divided. If necessary a Z- shaped incision is made over the proximal phalanx to excise the prolongation of the palmar fascia in the proximal and middle phalanges. After any operation a removable splint is used to maintain the corrected position. Amputation — may only be advised when the little finger is severely affected and the joint capsules are so secondarily contracted that it cannot be straightened even after fasciectomy. In this condition the fibrous sheath containing extensor pollicis brevis and abductor pollicis longus tendons becomes fibrosed and thickened, so that the intrathecal lumen becomes narrowed. It is on the lateral aspect of the lower end of the radius where the tendons lie in shallow bony groove. The cause is friction between the tendon sheath against the bone which leads to thickening and stenosing of the tendon sheath. Main symptom is pain on the radial side of the wrist particularly following actions like wringing cloths. On examination, a visible swelling may be seen just above the radial styloid process. Similarly pain becomes severe when the patient extends the thumb against resistance. Injection of hydrocortisone and xylocaine or novocaine to the thickened sheath is also effective. In this condition there is obstacle to voluntary flexion or extension of the finger.

It can Risk factors for strabismus include family history, low arise due to squint or due to a disease afecting the motor birth weight, maternal cigarette smoking, increasing mater- nerves (e. Esotropia compro- mises up to 60% of all types of strabismus in the West, Neural Control of Ocular Muscles with up to 90% of cases occurring before 5 years of age. Pathophysiology Related Disorders T ere are two major types of manifest strabismus: 1. Concomitant strabismus (from the Latin comitare , strabismus by suppressing the image from the deviating accompany): the deviating eye accompanies the leading eye to prevent the diplopia, resulting in amblyopia eye in every direction of movement. Amblyopia is not corrected by glasses, and if deviation remains the same in all directions of gaze. When strabismus develops in an adult (>7 years of age), it results in double vision (diplopia), and it usually arises due to cranial nerve injuries afecting the third, fourth, and sixth cranial nerves, ocular muscle disease (e. Heavy eye syndrome: heavy eye phenomenon presents as progressive esotropia and hypotropia in high myopia.

On the dynamic imaging, the left eye (arrows) is seen ﬁxed laterally by the action of an intact lateral rectus and paralyzed medial rectus muscle. The right eye, in contrast, is normally moving when the patient moves the right eye from the left side (a) into the right side (c) passing through the middle (b), when the patient is asked to move his eyes from right to left (arrowheads).

Treatment of “heavy eye syndrome” using superior oblique muscle, and its nucleus is located on top simple loop myopexy. Te end result is the movement of the medial rectus in the same direction of the lateral rectus muscle during eye 2. Only neurons that innervate the medial rectus muscle in the oculomotor nucleus receive this T e function of the ocular motor system is to hold images ascending, crossed input from the abducens nucleus stable on the fovea. Nystagmus is defned as the inability to maintain stable foveal vision, resulting in involuntary oscillation of the eyes (seeing illusionary movement in the visual feld). Sensory nystagmus results from aferent pathway disease of the globes, optic nerves, optic chiasm, or optic tracts in children who lose their vision before 4–6 months of age. A child who sustains bilateral loss of vision afer the age of 6 months will not develop sensory nystag- mus. Motor nystagmus, in contrast to sensory nystagmus, results from an anomaly of the central oculomotor control system. It is typ- ically binocular and conjugate and is associated with nearly normal visual acuity. So during head movement, the right semicircular which is important to stabilize gaze while the head is canal sends inputs regarding the position of the head in moving. Te past vestibulocochlear nerve, which in turn afect gaze via the neural pathway is known as the vestibulo-ocular refex, vestibulo-ocular refex. See-saw nystagmus: it is an uncommon form of nystagmus characterized by synchronous alternating elevation and intorsion of one eye, with simultaneous depression and extrusion of the other eye, followed by reversal of the vertical and torsional movement in the next half cycle. Periodic alternating nystagmus: it is a rare disorder where the patient complains from the acquired periodic. Horizontal nystagmus: it is an abnormal eye movement physiologically induced nystagmus via tilting the head that is restricted to the horizontal axis. Spasmus nutans: it is an acquired form of nystagmus double vision with oblique images due to monocular that typically presents between 6 and 12 months of age. Torsional nystagmus: it is a rare condition characterized is associated with normal vision.

After hemostasis is ensured, approximate the gastric and jejunal layers of the open stab wounds in an everting fashion with several Allis or Babcock clamps. Close the defect with one application of a 55 mm linear stapler deep to the line of Allis clamps (Fig. This staple line must include the anterior and posterior terminations of the anastomotic sta- ple line, guaranteeing that there is no defect between the two lines of staples. Excise the redundant tissue, lightly electro- coagulate the everted mucosa, and remove the stapler. Alternatively, close the stab wound defect in an inverting fashion by various suturing techniques. Then place a single 4-0 silk seromuscular suture at the right termination of the Fig. A three-dimensional representa- drain should be brought out from the vicinity of the duode- tion of the anastomosis is shown in Fig. The drain should be separated from the duodenal suture line by a layer of omentum. In the presence of an adequate drain, the appearance of duodenal content in the drainage ﬂuid with no other symptoms may not require vigorous therapy. On the other hand, if there are signs of spreading peritoneal irrita- tion, prompt relaparotomy is indicated. If no drain was placed during the initial operation, immediate relaparotomy is undertaken whenever there is reason to suspect duodenal leakage. On rare occasions relaparotomy can be performed before there is intense inﬂammatory reaction of the duodenal tissues, and the defect may be closed by suture. If suturing the virgin duodenum at the ﬁrst operation was not successful, an attempt at second- ary suturing fails unless considerable additional duodenum can be freed from the pancreas for a more adequate closure. Postoperative Care In most cases the operation is done to provide excellent drainage. A small sump-suction drain should be inserted into Nasogastric suction should be continued for several days.

Chassin† Indications Effective medical therapy has signiﬁcantly diminished the role for vagotomy in this setting. Not all free perforations of gastric ulcers are susceptible to simple plication techniques. When the perforation occurs on the poste- rior surface of the antrum, adequate repair by plication Fluid and electrolyte resuscitation, primarily with a balanced techniques is generally not possible. For these reasons, in a good-risk patient in Nasogastric suction whom the diagnosis of perforation has been made reasonably Systemic antibiotics early, gastric resection is preferred to simple plication. If for Monitoring of hourly urine output, central venous pressure, technical reasons a sound plication cannot be constructed, gas- or pulmonary artery wedge pressure, as indicated tric resection is mandatory, regardless of the risk, as a recurrent gastric leak into the peritoneal cavity is almost always fatal. Pitfalls and Danger Points Perforated Duodenal Ulcer Inadequate ﬂuid and electrolyte resuscitation Inadequate closure of perforation As with gastric ulcers, plication works best for small perfora- tions. Beware the large duodenal ulcer which Operative Strategy curves over the edge of the duodenum to become conﬂuent with a posterior ulcer. These may be associated with upper The most important initial step of the operative strategy is to gastrointestinal bleeding. They are difﬁcult to plicate because determine, on the basis of the principles discussed above, there is no easy way to completely close the perforation. On technical grounds alone, large defects in the stomach or duodenum are better handled by resection than by attempted plication. If it appears that plication of a duodenal ulcer would produce obstruction, resection is safer. An alter- native is excising the perforation as part of a pyloroplasty incision (see Chap.
