There are fractures of the B right superior and inferior pubic rami (white arrows) and wide separation of the ipsilateral sacroiliac joint (large black arrows) buy betnovate amex acne around chin. There is also some sacroiliac joint separation buy betnovate 20gm overnight delivery acne quiz, an avulsion of the L5 transverse process on the left 20 gm betnovate fast delivery acne 20s, and a fracture of the right pubic symphysis (small black arrow) quality betnovate 20 gm acne vs rosacea. Note the fractures of the left pedicle (black arrow) and transverse process (white arrows). LeFort I (transverse Fracture line oriented transversely through the Secondary to a local impact sustained over the fracture) maxilla (above the line of dentition). It involves upper lip region (alveolar process), this injury the nasal septum, the lower portions of the results in a separated fracture segment (floating pterygoid processes, and the medial and lateral palate) composed of the lower portion of the walls of the maxillary sinuses. After descending through the anterior maxillary walls near the zygomaticomaxillary sutures, the fracture line extends through the posterior maxillary sinus walls and across the pterygomaxillary fissures, ending in the lower pterygoid processes. After extending of the maxilla, the lacrimal bones, and the posteriorly across the orbital fissure, the fracture ethmoid bones (upper medial orbital bones). Usually occurs before (Fig B 34-1) the healing stage, the avulsion can have an ag- closure of the apophysis secondary to extreme gressive appearance, including lysis and des- active hamstring contractions, as in sprinting by truction. Chronic avulsions frequently result in runners or sudden and excessive passive lengthen- prominent bone formation. Patients typically present with pain in the buttock region, an antalgic gate, or inability to walk. Anterior superior Attachment site for the sartorius muscle and the Typically occurs in sprinters during forceful exten- iliac spine tensor muscle of the fascia lata. Patients complain of pain just below (Fig B 34-2) the most anterior aspect of the iliac crest. Anterior inferior iliac spine Origin of the straight head of the rectus femoris Results from forceful extension at the hip and heals (Fig B 34-3) muscle. Symphysis pubis Origin for the long adductor, short adductor, Virtually always due to chronic overuse, though (Fig B 34-4) and gracilis muscles. Note the protuberant bone (closed arrows) and a large, smooth Fig B 34-2 fragment (open arrows). Chronic avulsions are the result of repetitive microtrauma or overuse, usually develop from organized sports activities, and may be associated with a protuberant mass of bone that simulates a neoplastic or infectious process. Uncommon injury associated acutely with abrupt directional changes during motion or with repeti- tive microtrauma (as in long-distance runners). Uncommon injury that predominantly affects (Fig B 34-5) young athletes, who complain of considerable pain and decreased function. Greater trochanter Attachment site for the hip rotators, including Results from a sudden directional change. The (Fig B 34-6) the middle and least gluteal, internal obturator, diagnosis may be difficult to make if there is only gemellus, and piriform muscles. A lytic defect representing metastatic cancer is seen at the femur attachment site (open arrow). Patients present with pain at the lateral joint avulsed fragment lies immediately distal to the line and anterolateral rotational instability (rota- lateral tibial plateau and appears as an elliptical tional subluxation). Fibular head Attachment for the coronary, oblique popliteal, Results from force directed at the anteromedial (Fig B 34-8) and lateral (fibular) collateral ligaments. Associated injuries include tears of the anterior cruciate ligament and damage to the peroneal nerve. In adults, the injury is more often secondary to a motor vehicle injury in which the leg is hyperextended at impact (also more likely associated injuries, such as tear of the medial collateral ligament and focal bone contusions). Findings are often subtle, espe- (Fig B 34-10) cially if the fragment is not significantly displaced. Results from violent extension of the knee or (Fig B 34-11) passive flexion against contracted quadriceps muscles in sports that require jumping, squatting, and kicking. Although an acute injury, it is most frequently seen in young adolescents with ongoing Osgood-Schlatter disease (bilateral in up to 50%). Ankle and foot Calcaneal insufficiency Extra-articular fracture in the posterior third of Seen almost exclusively in diabetic patients, this (Fig B 34-13) the calcaneus that usually begins at the calca- injury is probably related to osteopenia and super- neal tuberosity and extends superiorly, with the imposed neuropathic changes.

Anterior capsule Protuberance of the anterior talus (“talar beak”) Occurs in basketball players and represents a (Fig B 34-15) at the insertion of the joint capsule. There is displacement of Inferior pole of the patella (white arrow- the proximal base of the epiphysis and head). Results from forceful contraction of the tendon against an inverted foot, as when stepping off a curb or tripping. In children, this horizontal fracture must be differentiated from the longitudinally oriented apophysis found at the lateral margin of the base of the fifth metatarsal. Shoulder and elbow Greater tuberosity Attachment site of the supraspinatus, infras- Patients present with a history of falling on an (Fig B 34-16) pinatus, and teres minor tendons. At radiography, the fracture may not be readily apparent and only seen on delayed images. Protuberance of the anterior talus (arrow) where the joint capsule is inserted, indicating a chronic avulsion. The avulsed lesser tuberosity may retract and lie inferior and medial to the glenoid (may be misinterpreted as calcific tendonitis of the biceps or subscapularis tendon). Medial epicondyle If acute, separation of the medial epicondyle Most commonly in adolescents and associated with (Fig B 34-18) with soft-tissue swelling. In chronic injury, there recurrent contraction of the flexor pronator group may be fragmentation and roughening of the of muscles during the acceleration phase of medial epicondyle. An entrapped fragment may simulate the trochlear ossification center and, if not recognized and removed, lead to disabling degenerative osteoarthritis. Typically an incidental finding on plain radiographs, on which the appearance is usually so characteristic that no additional imaging studies are required.

The presence of pain should suggest the possibility of a low-grade chondrosarcoma. Low-attenuation nidus within an area of thickened cortical bone in the lesser trochanter of the right femur. In this aggressive form, focal areas of bone formation within the lesion and invasion of the cortex simulate a malignant process. Chondromyxoid fibroma Eccentric metaphyseal lesion with well-defined Most commonly involves the knee and distal tibia. There is continuity of the cor- tex, which extends without interruption from the osteochondroma into the tibia.
Swelling purchase betnovate with a mastercard skin care vitamin c, brawny induration cheap 20 gm betnovate mastercard acne 9 year old, irregularity of the bone with multiple sinuses are the features of this condition buy betnovate with mastercard acne juvenil. There may be respiratory obstruction in case of neonates with micrognathism order betnovate 20 gm on-line acne zapping machine, as this deformity results in backward displacement of the tongue. Special airway plates should be used to prevent airway obstruction, which is much better than sewing of the tip of the tongue to the lower lip. Nowadays monoblock orthodontic appliance has been devised to correct this small mandible. Occasionally the maxilla may be hypoplastic producing a relative mandibular prognathism. Carcinoma of lip and Carcinoma of tongue occur more often in males above 50 years of age. While a mucous retention cyst usually occurs on the inner side of the lip or cheek and grows very slowly and presents for quite a long time; a cancer of the lip may present as a swelling or ulcer, gives a relatively short history though it is a slow-growing cancer and a cancer of the tongne gives an even shorter history. Pain is conspicuous by its absence in leukoplakia, mucous retention cyst and early stage of carcinoma of lip or tongue. If an old patient presents with ulcer of his tongue, but without pain, is an ominous sign. But it must be remembered that in late cases pain appears even in carcinoma of tongue. In certain late cases of carcinoma of tongue pain is referred to the ear of the affected side as lingual nerve and auriculotemporal nerve supplying the anterior surface of the external ear are both the branches of the mandibular nerve. If an old patient is seen in surgical outdoor holding handkerchief in his mouth, he is most probably suffering from carcinoma of tongue. Inability to protrude the tongue is a symptom of tongue-tie and late cases of carcinoma of tongue with invasion to the floor of the mouth. Difficulty in speech is the main complaint of cleft lip and cleft palate and carcinoma of tongue. Deviation of tip of the tongue when protruded towards the side of the lesion is a sign of carcinoma of tongue. Alteration of voice may be the first symptom in carcinoma of posterior 1/3 of the tongue which may remain unnoticed for quite sometime. To inspect the lips properly not only the outer surfaces of the lips are examined, but also the lips are retracted to see the mucosal surface of the lips. Similarly the cheeks are retracted outwards to see the buccal mucosal surface of the cheek as also the buccal side of the gum. To see the inside of the gum and floor of the mouth, the tongue is pushed away to one side or the other. For inspection of the tongue, the mouth is fully opened and the tongue is protruded to see the anterior 2/3rd of the tongue. To see th’e lateral aspect of its posterior third the tongue is pushed to one side or the other with a spatula. To see the fauces, tonsils and the beginning of the pharynx, one should depress the tongue with a spatula. Cleft lip may be complete when there is total failure of fusion and then the cleft extends upto the corresponding nostril. There may be bilateral complete cleft lip in which there is also a cleft palate and a protruberant pre-maxilla. This syndrome is a familial disease which is inherited by autosomal dominant gene and the main pathology lies in the small bowel in the form of adenomatous polyp which may cause intussusception or intestinal colic, but rarely undergo malignant change. Cracked lips are indolent cracks in the midline of the lower lip as a result of exposure to cold weather. Ectopic salivary neoplasms are usually seen in the upper lip as slow growing lobulated tumours. Carcinoma of the lip is seen in old individual which presents as erosion in the early stage — as red granular appearance with whitish flecks followed by yellowish crusting in the middle of the erosion. Congenital fissures are mainly transverse whereas syphilitic fissures are usually longitudinal, (d) Swelling and (e) An ulcer if any. If there is a swelling or an ulcer, note its site, size, shape, colour, surface, margin etc. Note also whether it has extended to the floor of the mouth, to the jaw or tonsil. Very rarely one can discover an angioma-like swelling in the region of the foramen caecum — this is lingual thyroid. This may be the only thyroid gland the patient possesses and therefore should not be removed. If the tongue deviates to one side during the protrusion, it indi cates impairment of nerve supply to that half of the tongue. This may be noticed in advanced carci noma of the tongue which has damaged the nerve supply of the consequent side. In case of a congenital cleft, note the extent of the cleft (involving only the uvula, only the soft palate or part or whole of the hard palate) and also whether the nasal septum is hanging free or is attached to one side of the cleft. Perforation of the hard palate is usually caused by gumma (syphilitic affection) (Fig. The student must be careful to note if there is any scar of operation around or such history, as sometimes a hole may persist after an operation for closure of a congenital cleft. A spatula and a torch will be essential to visualize more posterior portions of the gums. The earliest sign of pyorrhoea alveolaris is a deep red line along the free edge of the gum. Cancrum oris starts with a painful purple-red indurated papule found on the alveolar margin in the region of the molar or premolar teeth. Later on an ulcer forms which rapidly exposes the underlying bone and extends to the cheek and lip. A sublingual dermoid is opaque, lies exactly in the midline and may extend into the submental region. A deep or plunging ranula may have a cervical prolongation into the submandibular region. Such cyst may develop anywhere on the inner side of the lips and the cheek, though more common on the inner side of the lower lip and on the buccal mucous membrane of the cheek at the level of the bite of the teeth. Note that the carcinoma originally affected the lower lip and now ‘kiss lesion’ is seen in the upper lip. The head is bent to the side being palpated with one hand to relax the platysma and the muscles of that side of the neck for better palpation with the other hand. When carcinoma of lip is an ulcer hold the base of the ulcer with index finger an I thumb which is always hard. With one hand the lip is now fixed and with the other hand the lesion of the lip is held by two fingers and is attempted to move against the lip. Mucous retention cyst is often seen on the inner surface of the lip (mostly in the lower lip). For fluctuation test one should follow the technique for small swelling as mentioned in chapter 3 (page.

Surgical damage to the posterior pituitary with unrecognized diabetes insipidus is a good example purchase genuine betnovate on line acne kits. Bladder catheterization should be performed 6-8 hours post-operatively if no spontaneous voiding has occurred buy betnovate mastercard acne 7 months postpartum. Indwelling (Foley) catheter placement is indicated at the second (some say third) consecutive catheterization buy betnovate in india skin care with ross. Zero urinary output typically is caused by a mechanical problem purchase betnovate with amex acne 7061, rather than a biologic one. Look for a plugged or kinked catheter, and flush the tubing to dislodge any clot that may have formed. Dehydrated patients will respond with a temporary increase in urinary output, whereas those in renal failure will not do so. A more scientific test is to measure urinary sodium: it will be <10 or 20 mEq/L in the dehydrated patient with normally functional kidneys, while it will exceed 40 mEq/L in cases of renal failure. An even more scientific test is to calculate the fractional excretion of sodium, or FeNa. In order to calculate the FeNa, plasma and urinary sodium and creatinine must be measured. Early mechanical bowel obstruction because of adhesions can happen during the postoperative period. What was probably assumed to be paralytic ileus not resolving after 5-7 days is most likely an early mechanical bowel obstruction. Ogilvie syndrome or pseudo-obstruction is a poorly understood (but very common) condition that could be described as a “paralytic ileus of the colon. Patients develop abdominal distention without tenderness, and x-rays show a massively dilated colon. Wound dehiscence is typically seen around post-operative day 5 after open laparotomy. The wound looks intact, but large amounts of pink, “salmon- colored” fluid are noted to be soaking the dressing; this is peritoneal fluid. Evisceration is a catastrophic complication of wound dehiscence, where the skin itself opens up and the abdominal contents herniate. It typically happens when the patient (who may not have been recognized as having a dehiscence) coughs, strains, or gets out of bed. The patient must be kept in bed, and the bowel covered with large sterile dressings soaked with warm saline. If it does not empty completely to the outside but leaks into a body cavity, an abscess may develop and lead to sepsis; complete drainage is the required treatment. Every 3 mEq/L that the serum sodium concentration is >140 represents roughly 1 L of water lost. The condition results in water loss from cells and typically presents as alterations in neurologic function. The extent of brain dysfunction depends on the magnitude and time frame over which the hypernatremia developed. Treatment requires volume repletion, but done in such a way that volume is corrected rapidly (in a matter of hours) while tonicity is only gently “nudged” in the right direction (and goes back to normal in a matter of days). Hyponatremia means that a net excess of water has been retained and hypotonicity has developed, but there are 2 different scenarios (easily distinguishable by the clinical circumstances). Hypokalemia develops very rapidly (over hours) when potassium moves into the cells, most notably when diabetic ketoacidosis is corrected. Hyperkalemia will occur slowly if the kidney cannot excrete potassium (renal failure, aldosterone antagonists) and it will occur rapidly if potassium is being dumped from the cells into the blood (crushing injuries, dead tissue, acidosis). When abnormal acids are piling up in the blood, there is also an “anion gap” (serum sodium exceeds by >10 or 15 the sum of chloride and bicarbonate), which does not exist when the problem is loss of buffers. Treatment in all cases must be directed at the underlying cause, though in all cases administration of bicarbonate (or bicarbonate precursors, like lactate or acetate) will temporarily help correct the pH. Bicarbonate therapy, however, risks producing a “rebound alkalosis” once the underlying problem is corrected. Thus correction of the underlying problem—rather than bicarbonate administration—is the preferred therapy. In long-standing acidosis, renal loss of + K leads to a deficit that does not become obvious until the acidosis is corrected. Such patients present + - with low K , low Cl , and high bicarbonate (hypokalemic, hypochloremic metabolic alkalosis). Treatment involves replacement of chloride and potassium, thereby allowing the kidneys to correct the problem. Respiratory acidosis and alkalosis result from impaired ventilation (acidosis) or abnormal hyperventilation (alkalosis). It is important to note that metabolic acid-base derangements may be accompanied by respiratory “compensatory” changes. In more typical cases, an overweight individual complains of burning retrosternal pain and “heartburn” that is brought about by bending over, wearing tight clothing, or lying flat in bed at night; it is relieved by the ingestion of antacids or over-the-counter H2 blockers. When the diagnosis is uncertain, pH monitoring can be helpul to establish the presence of reflux and its correlation with the symptoms. If there is a long-standing history, the concern is the damage that might have been done to the lower esophagus (peptic esophagitis) and the possible development of Barrett’s esophagus. In that setting, endoscopy and biopsy are the indicated tests, as Barrett’s is a precursor to malignancy. Surgery for gastroesophageal reflux is: Appropriate in long-standing symptomatic disease that cannot be controlled by medical means (using laparoscopic Nissen fundoplication) Necessary when complications have developed (ulceration, stenosis) (using laparoscopic Nissen fundoplication) Imperative if there are severe dysplastic changes (resection is needed) Motility problems have recognizable clinical patterns, such as crushing pain with swallowing in uncoordinated massive contraction, or the suggestive pattern of dysphagia seen in achalasia, where solids are swallowed with less difficulty than liquids. There is dysphagia that is worse for liquids; the patient eventually learns that sitting up straight and waiting allows the weight of the column of liquid to overcome the sphincter. The most appealing current treatment is balloon dilatation done by endoscopy; however, recurrence is high and many patients ultimately require an esophagomyotomy (Heller). Cancer of the esophagus shows the classic progression of dysphagia starting with meat, then other solids, then soft foods, eventually liquids, and finally (in several months) saliva. Adenocarcinoma is the more common form of cancer in people with long- standing gastroesophageal reflux. Mallory-Weiss tear is a mucosal laceration at the junction of the esophagus and stomach. It occurs after prolonged, forceful vomiting and presents with bright red hematemesis. Endoscopy establishes diagnosis, and allows treatment with endoscopic clipping or coagulation. Boerhaave’s syndrome is rupture (perforation) of the esophagus that results from prolonged, forceful vomiting. There is continuous, severe, wrenching epigastric and low sternal pain of sudden onset, soon followed by fever, leukocytosis, and a very sick-looking patient. Contrast swallow with a water- soluble agent (Gastrografin) is diagnostic and emergency surgical repair should follow.

The image in (a ) reﬂects fat density (represented in white), and the other nonfatty tissues are removed (represented in black). The volume must be multiplied by the slice thickness of the original image to get the fat volume in cm3 Fluoroscopic barium meal examination is performed to confrm the absence of leakage. Te normal images should detect abnormalities and complications of gastric banding. The herniated band edge is seen as a barium filling defect within the stomach on barium examination (pathognomonic). Patients with this kind of obstruction often present with esophageal dysmotility, vomiting, and pseudoachalasia. Patients may be asymptomatic (20 %) or may present with epigastric pain, vomiting, and progressive gastroesophageal reflux disease. If not corrected, band slippage can lead to gastric volvulus and gastric necrosis. Crush syndrome is a pathological condition characterized by severe shock and hypotension, anuria, coma, and death. Classically, the disease is caused by muscle disintegration that releases myoglobin into the circulation, which has toxic efect over the renal glomerulus. During liposuction, the numerous tunnels created through the fat create a mechanism of subcutaneous injury similar to crush syndrome. Also, uncontrolled cannula movements may cause muscle injury, creating crisscrossed tunnels that may produce large cavities. Tese large cavities result in third space fuid loss, which produces severe symptoms. Tese free fatty acids are toxic to the into the dilated gastric pouch (arrowhead ) pneumocytes and the capillary epithelium, producing chem- ical pneumonitis.
