A careful search should be made to locate the source of infection purchase discount viagra gold line, which should be treated as soon as possible buy 800 mg viagra gold free shipping. Only when this is associated with secondary infection a few of these features may be present purchase generic viagra gold line. Cold abscess is almost always a sequel of tubercular infection anywhere in the body commonly in the lymph nodes, bone and joint. So cold abscess may travel a long distance along definite anatomical plane or tracing a nerve or a vessel. If the cold abscess continues to be present, aspiration may be attempted obliquely through the normal surrounding skin and not through the most prominent and most dependent part as this will invariably cause sinus formation. If the local abscess still persists, the affected group of lymph nodes should be excised as a whole. A word of caution is highly important, that an incision should not be made on a cold abscess for drainage, as it almost always invites secondary infection and forms a persistent sinus. This consists of a series of communicating abscesses, which discharge by separate openings on the surface. Individual compartments in the carbuncle are maintained through persistence of fascial attachment to the skin. There is a central large slough, surrounded by a rosette of small areas of necrosis. In untreated cases infection may extend widely with fresh openings appear on the surface, which coalesce with those previously formed. Under treatment when the central slough is drained off, fibroblastic reactions start from the surrounding granulation tissue and carbuncle heals with a characteristic induration. It commences as painful and stiff swelling which spreads very rapidly with marked induration. These pustules subsequently burst allowing the discharge to come out through several openings in the skin producing a sieve-like or cribriform appearance, which is pathognomonic of carbuncle. Finally the slough separates leaving an excavated granulation tissue, which heals by itself. When the resistance of the individual is poor in diabetic subject, the sloughing process may extend deeply into the muscle or even bone. Constitutional symptoms and toxaemia vary according to the degree of the resistance of the individual and efficacy of the treatment. At this time a paste composed of anhidrous magnesium sulphate and glycerin may be applied or S. This will exercise a valuable osmotic affect and will not only reduce oedema but also will help to burst the carbuncle. Operation may be required (a) when toxaemia and pain persist even after a course of antibiotics and (b) when the carbuncle is more than 2Yi inches in diameter. It must be remembered that incision is never made unless there is softening in the centre. The part should be kept in perfect rest for a week and antibiotic is continued till resolution. The term is a misnomer, as the lesion is one of the connective and interstitial tissue and not of the cells. The causative organism is mostly the Streptococcus pyogenes, though a variety aerobic and anaerobic bacteria may produce cellulitis. There is wide spread swelling and redness at the area of inflammation, but without definite localization. The causative organism is usually Streptococcus haemolyticus group A (Strep, pyogenes). The disease spreads from the site of inoculation and the advancing margin becomes bright, red and slightly raised above the general surface. It should be remembered that whereas in ordinary streptococcal infections the characteristic defence cell is the polymorphonuclear leucocyte, in erysipelas this cell is small mononuclear cell. Following the fading of the inflammation, brown discolouration of the skin may remain. The condition commences as a rose-pink rash which extends to the adjacent skin like a drop of grease spreading on a piece of paper. Sloughing or gangrene rarely occurs particularly in grossly debilitated or diabetic individuals. Lymphoedema may rarely occur due to lymphatic obstruction, which occurs more in parts containing loose areolar tissues e. Although the best example is tuberculosis, yet other conditions may present caseous necrosis e. Fibrinoid necrosis appears in the granulomatous nodules which are seen in rheumatoid arthritis and rheumatic fever. Infection by inhalation is by human type of tubercle bacillus in the form of tiny droplets spread out by cough of the tuberculous patients. Infection by ingestion may occur due to ingestion of milk containing bovine form of tubercle bacilli coming from tuberculous cow. However this type of infection is almost unknown nowadays as pasteurization of milk has been enforced by law. It is often due to ingestion of cough or infected material of human type of tubercle bacilli that this type of infection may occur. This infection may spread to the retroperitoneal groups of lymph nodes, follow the lymphatic path and may ultimately reach the blood stream. A rare form of infection is through the skin (cutaneous spread) in those engaged in occupations e. The histiocytes are members of the reticuloendothelial system which are derived locally from the primitive mesenchyme of the connective tissues, from lining cells of the sinuses in the liver, spleen, lymph nodes and bone marrow. These histiocytes retain a high degree of power of phagocytosis, amoeboid movement and independent proliferation. These cells ingest bacteria and cell debris so that their cytoplasms swell and individual histiocytes gradually assume epitheloid appearance which are known as epitheloid cells. The epitheloid cell has a large vesicular nucleus and a clear cytoplasm and a few processes which may anastomose with the neighbouring cells to form an epitheloid reticulum. In addition to the epitheloid cells, one or more cells may be seen situated usually toward the centre, but occasionally at the periphery of the tubercle. These cells are much bigger than the epitheloid cells and contain many nuclei (20 or more) characteristically grouped. These cells are called foreign body giant cells and usually contain tubercle bacilli. Though giant cells are characteristic of tuberculosis but these are also found in syphilis and actinomycosis and even around foreign bodies e. For the first few days the tubercle consists entirely of the epitheloid cells and giant cells.

Preventing Incomplete Vagotomy In most cases of recurrent marginal ulcer, it turns out that the posterior vagal trunk has not been divided. The right (posterior) vagal trunk is frequently 2 cm or more distant from the right lateral wall of the esophagus. It is often not delivered into the field by the usual maneuver of encircling the esophagus with the index finger. If the technique described below is carefully followed, this trunk is rarely overlooked. To improve tissue recognition skills, the surgeon should place each nerve specimen removed from the vicinity of the esophagus into a separate bottle for histologic examination. The pathology report that arrives several days after the operation can serve as a test of the surgeon’s ability to identify nerves visually. The surgeon may be surprised to find that four or five specimens of nerve have been removed during a complete truncal vagotomy. Frozen section examination is helpful but not conclusive because it cannot prove that all the vagal nerve branches have been removed. The surgeon must gain sufficient skill at identifying nerve trunks to be certain no significant nerve fiber remains. Hiatus Hernia Significant hiatal hernia following vagotomy occurs in no more than 1–2 % of cases. This percentage can probably be reduced if the surgeon repairs any large defects seen in the hiatus after the dissection has been completed.

Haemangioma may occur anywhere in the body though it is more common in the skin and subcutaneous tissues discount viagra gold online visa. This red mark gradually increases in size for a few months till it takes a typical strawberry or raspberry like swelling buy viagra gold 800mg cheap. Very rarely submucous strawberry angioma has been seen when it is prone to alarming haemorrhage buy viagra gold 800 mg fast delivery. This slightly protrudes from the skin surface and appears as a sessile haemisphere. The surface is irregular and there may be small areas of ulceration covered with scabs. Sustained pressure will squeeze most of the blood out of the haemangioma leaving it collapsed. In this respect 3% sodium morrhuate is quite effective otherwise boiling water or hypertonic saline may be tried. A needle is pushed into the haemangioma and its end is touched with a diathermy node. Such cirsoid aneurysm is commonly seen on the forehead or in the scalp over the temporal region. Peculiarly enough this is the drainage area of superior vena cava though its relationship cannot be explained. Spider naevus is usually associated with hepatic disease (particularly hepatic cirrhosis or tumours destroying the liver) and tumours producing oestrogen. This usually occurs on the extremities particularly in the nail-beds of the hands and feet. Between these cells there are numerous medullated and non- medullated nerve fibres, though the latter outnumber the former. Such glomus is most abundantly present in the region of the nail-bed at the tips of the fingers and toes and the palmar surface of phalanges. The glomus tumour or the glomangioma is a benign and circumscribed tumour blue or reddish in colour. Plain muscle fibres intervene between the lumen and the clumps of epitheloid cells. Abundant nerve fibres mainly nonmyelinated variety are seen between the epitheloid cells and these are responsible for exquisite pain which is the most important symptom of suqh tumour. Pain is probably caused by dilated glomus vessels pressing on the numerous nerve endings. Subungual sprouting granulation tissue resulting from chronic osteomyelitis of the distal phalanx. Localized cluster of dilated lymph sacs in the skin and subcutaneous tissues which cannot connect into the normal lymph system grows into lymphangioma. Occasionally the vesicles may be rubbed with the clothes, get infected and become painful. When excision is complete there is no chance of recurrence and cure is complete and permanent. A hamartoma is a developmental malformation consisting of a tumour-like overgrowth in which the tissues of a particular part of the body are arranged haphazardly, usually with an excess of one or more of its components. Common lesions included in this group are benign pigmented moles, majority of angiomas and neurofibromas. A very well known example of hamartoma is the isolated cartilaginous mass found in the substance of a lung. On section it is found to be composed of mature hyaline cartilage with clefts lined by respiratory epithelium and surrounding the cartilaginous mass there is connective tissue and smooth muscle. But usually only those on exposed areas like the skin and mouth will be recognized as early as this. Other tumours will be recognized late, though no doubt the original nidus was present at birth. It grows alongwith its surroundings, so there is no question of any connective tissue condensation. False neuromas are those which arise from the connective tissue covering the nerve fibre or from the nerve sheath. The sympathetic system originates from the neural crest and develops along 2 lines :— (a) Primitive neuroblasts and adult sympathetic cells which may give rise to tumours such as neuroblastoma and ganglioneuroma respectively, (b) Chromaffin tissue situated mostly in the adrenal medulla and may produce tumours known as pheochromocytoma. It must be remembered that whereas schwann cells are derived from the neural crest, neurilemmoma is ectodermal in origin. Neurofibroma arises from elements of perineurium and endoneurium and are mixtures of ectoderm and mainly mesoderm. Neurilemmoma is a benign, well encapsulated tumour which forms a single, round or fusiform firm mass on the course of one of the larger nerves. Multiple lesions may occur on the same nerve or may be distributed throughout the body. Such neurilemmomas are occasionally seen in the posterior mediastinum and in the retroperitoneal space. The long slender cells form twisted band and have elongated nuclei which show palisading arrangement or are arranged in whorls. Basically two types of tissue can be noticed in such a tumour — fascicular and reticular tissues. The fascicular tissue presents a solid complex appearance almost like an exaggerated tactile corpuscle, known as Verocay body. The reticular tissue consists of loosely arranged schwann cells in an open network of tiny cysts and reticulin fibres. The neurilemmoma is essentially a benign lesion and does not show any tendency to malignant transformation. This is a developmental disorder and is often considered as Hamartoma and not a typical tumour. Majority of the neurofibromas arise from endoneurium, the innermost connective tissue covering of the nerve fibre. The endoneurium is covered by perineurium and epineurium, which remain usually unaffected. Paraesthesia or pain likely to occur from pressure of the tumour on the nerve fibres. On examination, it is a smooth firm swelling of the skin and subcutaneous tissue which occurs along the course of a nerve. Both the area of sensation and the muscle power of the nerve involved should be examined. In such cases excision may accompany resection of the involved portion of the nerve and then end-to- end anastomosis of the divided nerve is performed. Type I is a relatively common disorder and 50% of patients give a definite family history. Typically these components are dispersed in a loose disorderly pattern, often in a loose myxoid stroma.

Neonatal adrenal hemorrhage may be related to the trauma of delivery purchase 800mg viagra gold overnight delivery, septicemia generic viagra gold 800mg on line, asphyxia generic viagra gold 800 mg with amex, or abnormal clotting factors. They may also result from degenerative necrosis and hemorrhage into an adrenal mass. Areas of hemorrhage can be differentiated from fat by comparing the appearances on non–fat saturation and fat saturation images. T2-weighted image with fat obtained 6 weeks after a motor vehicle accident shows the saturation shows a uniformly hypointense right concentric rim sign, suggestive of a subacute hematoma. Neuroblastomas arise from on T2-weighted images, with evidence of the neural crest in the adrenal medulla or along the contrast enhancement. Axial T1-weighted image shows bilateral lymphomatous deposits as areas of low signal intensity. May produce only State and Europe, it occurs most frequently in older focal bladder wall thickening or invade the men. Punctate, coarse, or linear contact of the bladder urothelium with urine calcification (5%) typically encrusts the surface containing carcinogens, predominantly from of the mass rather than lying within it. There is also a well-documented link with bladder wall and tumor are of intermediate a variety of occupational and environmental signal intensity. Most urothelial tumors are located at ideal for detection of extravesical infiltration the bladder base (80%); 60% are single and more into high-signal fat. They often are intermediate-signal tumor contrasts with the multicentric, with synchronous and metachronous high signal intensity of urine and low signal tumors of the bladder and the upper urinary tract. These sequences are best for evaluating tumor depth, differentiating tumor from fibrosis, and detecting invasion of surrounding organs and marrow metastases. Urachal carcinomas are usually located at the dome of the bladder, in or slightly off the midline. Most adenocarcinomas are aggressive lesions that demonstrate early extravesical spread. Metastases Various patterns depending on the source of Most commonly the result of direct invasion from spread. Less frequently, bladder metastases may develop from hematogenous or lymphangitic spread of cancers from the stomach, breast, or lung. A late manifestation of cancer, when bladder metastases are detected there is usually evidence of a locally invasive adjacent primary neoplasm or other signs of a distant primary tumor. Small cell/neuroendocrine Large, polypoid or nodular lesion with patchy Rare, highly aggressive tumors that are frequently tumor contrast enhancement that may have an associated with a history of cigarette smoking.

Intramural solid and cystic inflammatory cells with myxoid components that pseudotumor variants also occur. At times, malacoplakia may be extremely aggressive, invading the perivesical space and even causing bone destruction. Axial T2-weighted image in another patient shows a lobulated polypoid mass arising from the anterior wall of the bladder. Note the central hyperintensity (*) and low peripheral signal intensity (arrowhead). The characteristic calcification in chronic disease represents large numbers of calcified eggs within the bladder wall. Other signs of pelvic Crohn’s disease may include fibrofatty proliferation, infiltration of fat, phlegmon, and lymphadenopathy. Radiation and Focal or diffuse irregular thickening of the Severe hemorrhagic cystitis may develop after chemotherapy cystitis bladder wall in acute cystitis. A small bowel series (not shown) showed a fistula connecting the abnormal segment of ileum to the bladder. Despite its large size, this “mass” proved to be benign hypertrophy of the prostate. Anterior urethral injury generally results from a straddle pelvic injury and is most often isolated. When there is blood in the meatus, which is present in about half of significant urethral injuries, retrograde urethrography should be performed immediately to assess for urethral injury. Fluoroscopic observation after contrast injection into the corpora cavernosum may show the exact site of a tunica albuginea tear, which may not be evident at surgery. Postirradiation Narrowing or fistulization Urethritis, urethral stricture, and urethral fistula may develop following radiation therapy. Stretching of the posterior urethra with complete rupture of the posterior urethra. The underlying cause is thought to be activated proteolytic exocrine enzymes from the transplanted pancreas. Acquired inflammatory disease Gonococcal and other Irregular narrowing (stricture) or extensive Gonorrheal infection remains the leading urethritis extravasation (fistula). Serious complications requiring imaging include urethral stricture, periurethral abscess, and periurethral fistula. Also known as “venereal warts,” in up to 5% of male patients they may extend to the prostatic urethra and bladder. The diagnostic procedure of choice is voiding cystourethrography, because retrograde urethrography may result in retrograde seeding. Tuberculosis Anterior urethral stricture associated with Rare urinary tract manifestation of tuberculosis. Genital disease is a descending infection, and renal tuberculosis is usually evident. Rupture of a prostatic abscess into surrounding structures may lead to the development of fistulas to the urethra.

Unlike a pancreatic pseudocyst, it is not associated with high levels of amylase or lipase in the cystic fluid. Retroperitoneal lymphoceles may cause venous obstruction with subsequent edema and throm- boembolic complications.

It also can occur in a spontaneously breathing patient if the subclavian vein is opened to the air (e buy viagra gold with american express. Immediate management includes cardiac massage buy viagra gold with paypal, with the patient positioned in Trendelenburg with the left side down to “trap” air in the atria until it can be absorbed or aspirated order viagra gold in united states online. Prevention of air embolism includes use of the Trendelenburg position when the great veins at the base of the neck are to be accessed. Fat embolism may also produce respiratory distress in a trauma patient who is without direct chest trauma. The typical setting is the following: Patient with multiple traumatic injuries (including several long bone fractures) develops petechial rashes in the axillae and neck; fever, tachycardia, and low platelet count At some point patient develops a full-blown picture of respiratory distress, with hypoxemia and bilateral patchy infiltrates on chest x-ray The mainstay of therapy for fat embolism is respiratory support. Other therapies for this syndrome including heparin, steroids, alcohol, or low-molecular-weight dextran have been discredited. Penetrating trauma is further differentiated into gunshot wounds and stab wounds as the pattern of injury based on mechanism is quite different. Gunshot wounds to the abdomen require exploratory laparotomy for evaluation and possible repair of intra-abdominal injuries, not to “remove the bullet. However, the presence of protruding viscera or the development of peritoneal signs/evidence of ongoing bleeding requires exploratory laparotomy. If the fascia is not violated, the intra-abdominal cavity likely has not been penetrated and no further intervention is necessary. If the fascia has been violated, surgical exploration is indicated to evaluate for bowel or vascular injury, even in the setting of hemodynamic stability and lack of peritoneal findings on physical examination. Blunt trauma to the abdomen with obvious signs of peritonitis or suspected intra-abdominal hemorrhage requires emergent surgical evaluation via exploratory laparotomy. Signs of internal injury include abdominal distention and significant abdominal pain with guarding or rigidity on physical examination consistent with peritonitis. The occurrence of blunt trauma even without obvious signs of internal injury requires further evaluation because internal hemorrhage or bowel injury can be slow and therefore present in a delayed fashion. Patients tend to be cold, pale, anxious, shivering, thirsty, and perspiring profusely. These signs of shock occur when 25–30% of blood volume is acutely lost, ~1,500 ml in the average-size adult. There are few places in the body that this volume of blood can be lost without being obvious on physical or radiographic exam. The pleural cavities could easily accommodate several liters of blood, with relatively few local symptoms, but such a large hemothorax would be obvious on chest x-ray, which is routinely obtained as part of the primary survey in a trauma patient. This volume of bleeding could also occur with a pelvic fracture and > 1 liter of blood can be lost with a mid-shaft femur fracture. That leaves the abdomen, retroperitoneum, thighs (secondary to a femur fracture), and pelvis as the only places where a volume of blood significant enough to cause shock could “hide” in a blunt trauma patient that has become unstable. The femurs and pelvis are always checked for fractures in the initial survey of the trauma patient by physical exam and pelvic x-ray. So any patient who is hemodynamically unstable with normal chest and pelvic x-rays likely has intra-abdominal bleeding. Ultrasound is an important, readily available, adjunct to identify intra-abdominal and pericardial fluid. Fluid is not typically present in these locations, so if there is a clinical suspicion such as hypotension following blunt trauma, consider an internal injury. A stable patient in whom the diagnosis is less definite should undergo a more definitive study, i. Additionally, grading scores exist for the extent of solid organ injury, with specific guidelines as to when a surgical intervention is indicated versus observation. Generally speaking, a patient with intra-abdominal bleeding injury from the liver or spleen can be observed as long as they are hemodynamically stable or respond to fluid and blood product administration; the moment instability is mentioned in a vignette, surgical exploration is indicated. If surgical exploration is indicated for penetrating or blunt trauma, certain principles must be employed. Prolonged surgical time and ongoing bleeding can lead to the “triad of death”: hypothermia, coagulopathy, and acidosis. The longer a patient is open, the worse these components get, and they can interact in a vicious cycle ultimately leading to death. Accordingly, the “damage control” approach has been adopted: that is, immediate life-threatening injuries are addressed, less urgent injuries are temporized or left to be addressed at a later time point. If a bowel resection is necessary, reconstruction can be delayed as only the contamination is life-threatening, not the inability to digest food. If hypothermia, coagulopathy, or acidosis is setting in and injuries have been controlled, the operation is terminated and the abdomen is closed with a temporary closure. This most realistically mimics the replacement of whole blood and provides not only hemoglobin, but also adequate clotting factors to reverse the developing coagulopathy and enable control of hemorrhage. Abdominal compartment syndrome is when the pressure in the peritoneal cavity is elevated and and exceeds the capillary perfusion pressure leading to end-organ injury. This occurs when a significant amount of fluid is administered in an effort to resuscitate a patient in hypovolemic shock. First, the elevated pressure leads to decreased perfusion pressure to the viscera, contributing to acute kidney injury and possibly bowel and hepatic ischemia. Therefore, if bowel edema is observed or intra-abdominal pressure is elevated following surgical exploration, the abdomen is not closed but rather left open as described in the damage-control approach. Similarly, if a patient is not surgically explored but undergoes a significant volume resuscitation and abdominal compartment syndrome develops, a decompressive laparotomy may be indicated. Incidentally, this can occur in non-trauma scenarios requiring massive fluid resuscitation, most notably severe pancreatitis. A ruptured spleen is the most common source of significant intra-abdominal bleeding in blunt abdominal trauma. Often there are additional diagnostic hints, such as fractures of lower ribs on the left side. Given the limited function of the spleen in the adult, a splenic injury resulting in hemodynamic instability or requiring significant blood product transfusion is an indication for splenectomy. Post-operative immunization against encapsulated bacteria is mandatory (Pneumococcus, Haemophilus influenza B, and Meningococcus). However, lesser injuries to the spleen which can be repaired easily are attempted. In pelvic fracture with ongoing significant bleeding causing hemodynamic instability, management is complex. The first step for an obvious pelvic fracture in an unstable patient is external pelvic wrapping to provide some stabilization of the pelvis, thereby limiting the potential space for ongoing blood loss. In most cases angiography, not surgical exploration , is the next step in managing hemorrhage from serious pelvic fracture. This is because it is incredibly difficult (often impossible) to identify the source of bleeding in the pelvis where a deep cavity contains significant organs and vessels including the complex sacral venous plexus. However, interventional radiologists can angiographically identify an arterial source of bleeding and potentially embolize the branch vessels and control hemorrhage. If no arterial bleeding is identified, the ongoing blood loss is presumed to be venous in origin, and the internal iliac arteries are prophylactically embolized to prevent the inflow to these bleeding veins. These include injuries to the rectum (do a rectal exam and rigid proctoscopy), vagina in women (do a manual vaginal exam); urethra in men (do a retrograde urethrogram), and bladder (addressed in the next section).

Melanomas of the head and neck present particular prep, for example, a melanoma of the anterior trunk which challenges (see references at the end). However, in many cases, it will be Incise the skin sharply and deepen the incision straight necessary to reposition the patient and re-prep and redrape to down to the deep fascia. Grasp one end of the specimen with provide optimum exposure for both portions of the operation. If this step is performed immediately rior) and submit it for pathological examination. We rarely use a subcuticular closure for this purpose, as the incision is gener- ally under some tension. This decision is best made at the initial part of the procedure and the incision outlined accordingly. Sentinel Lymph Node Biopsy Reposition and drape the patient, if necessary, to provide optimal exposure of the appropriate nodal basin as deter- mined by the lymphoscintigram. Use the sterile gamma probe to identify the region of greatest radioactivity and make an incision directly over this spot. Plan the incision so that it could be excised easily during a subse- quent lymphadenectomy, should this be required. If it is necessary to divide a lym- phatic trunk, secure it with clips or ties to minimize seroma formation. Any palpably or visibly abnormal nodes should be background (post-excision) count is less than 10 % of the removed.

The technique consists of injection of a dye (10 ml of 35% diodone) into the common carotid artery followed by skiagraphy immediately buy viagra gold 800 mg line. It should be said in the passing that this investigation can only be performed when the patient’s condition is not so acute and he does not require immediate operation generic viagra gold 800mg without prescription, as this is a time consuming investigation buy viagra gold 800mg without a prescription. Carotid angiography will indicate the presence of subdural haematoma by displacement of the cortical vessels away from the inner table of the skull. In case of extradural haemorrhage the middle cerebral artery will be displaced inward and the anterior cerebral artery will also be displaced to the opposite side across the midline. If there be subtemporal haematoma or subcortical bleeding in the temporal lobe, the middle cerebral artery will be displaced upward. Measurement of intracranial pressure has a clear role in the management of patients with head injuries particularly with intracranial haematomas. But the expertise needed to measure intracranial pressure accurately may not be available in many institutions. Its particular value is in postoperative care after the haemorrhages have been operated on. Its value in indicating the type of haemorrhage and its site before operation is still very doubtful. It should be remembered that an extremely high intracranial pressure may shut off cerebral blood flow. It conveys much more informations about the intracranial contents than any previous technique. The patient lies on a movable couch, so that the part to be investigated can be moved within the scanning gantry. The information is fed into a computer and it produces a record in which high density objects e. It also demonstrates lesions such as contusions and presence of tumours, infarctions, ventricular displacement and hydrocephalus. Its major importance lies in detecting clots in atypical positions, which arc always missed in other investigations. This investigation has become also Valuable in chalking out a rational and coordinated strategy for head injury management. The various drugs which are used in this respect are the osmotic diuretics, steroids, hyperventilation and barbiturates. This is given intravenously to an adult in a volume of 250 ml over the course of 20 to 30 minutes (0. The students are hereby cautioned about the potential dangers of the use of such intravenous mannitol. Care must be taken to see that (i) satisfactory renal function is maintained, (ii) fluid and electrolyte replacement should be accurate and (iii) if the blood becomes hyperosmolar, the rate of administration should be minimised. Students are further cautioned against indiscriminate use of this agent in all cases of head injury. This should not be used in the acute stage when possioility of intracranial haemorrhage has not been excluded. But in certain cases to get more time before surgery, such agent may be used with care. In high doses they have been used in head inj ury cases (Dexamethasone or Betamethasone in the dose of 60 mg/day). But even at present there is no clear evidence that steroids do improve the outcome of head injury cases. Although hyperventilation has been used frequently in Western Countries in head injury cases, there is no convincing evidence of its value. On the whole the effectivity of various medicines just described above in head injury cases is still debatable. Whenever possible intracranial haematomas should be evacuated as expeditiously as possible and the rest is treated with a high standard of intensive care. The ultimate outcome of the patients depends mainly on the severity of brain damage. These are usually treated with prophylactic antibiotics (mainly broad spectrum effective against gram-positive and gram-negative organ­ isms). Such aerocele is seen in the subarachnoid space or in the substance of the frontal lobe or in the ventricular system. Neck stiffness, which is a common sign of meningitis, is also seen in case of subarachnoid bleeding. Lumbar puncture to diagnose meningitis should not be done casually and is only performed when its indication is clear and there are no signs of cerebral compression. In cerebral compression there is a risk of pressure-cone being formed by the impaction of medulla into the foramen magnum while draining the cerebrospinal fluid. The finding of fresh petechiae over the upper part of trunk and in the axilla is of fat embolism. The pupils which vary in size from moment to moment but remain equal with presence of retinal haemorrhages are signs of fat embolism. This is often due to increased intracranial pressure of the supratentorial compartment. The typical features are extensor spasms of all 4 limbs, arching of the trunk (opisthotonus), a rapid pulse, rapid and shallow respiration, small pupils and pyrexia. The most important physical sign is shallow an irregular respiration followed by deterioration of level of consciousness. Profound fall in blood pressure, tachycardia and hypothermia are seen with deterioration in level of consciousness. High dosage of steroids should be given in the dose of hydrocortisone — 200 mg 6 hourly on 1st day followed by reduced and maintenance dosage later on. This pericranium is attached firmly at the sutures of the skull so osteomyelitis of the skull is usually limited to the bone concerned. Osteomyelitis of the skull causes pitting oedema of the scalp over the affected area and this collectively known as ‘Pott’s puffy tumour’. Gradually the blood supply to the skull gets damaged and therefore necrosis and sequestration of the bone may take place. Sometimes the infection may remain indolent for sometime and only manifests itself by drainage through an area of scalp. More often the infection is quite virulent and may spread into the intracranial structures. Care must be taken to be certain that no infection remains in the extradural space after excision of the bone. In case of middle ear infection, it commonly reaches extradural spread through the tegmen lympani. When an epidural abscess is formed, the dura mater acts as a protective barrier against inward spread of infection. But unfortunately infection often breaks through the dural barrier and has resulted in meningitis or brain abscess. Infection may spread into the subdural space by direct extension along emissary veins and dural sinuses. Tenderness can be elicited over the area of extradural abscess by percussion on the local area of the skull.
