Colonoscopy allows evaluation of the involvement of colonic mucosa, and in most cases it can be extended to the distal ileum (ileocolonoscopy). Moreover, at endoscopy multiple biopsies are routinely obtained, which is considered extremely important for confirming the diagnosis of Crohn disease. Cross-sectional imaging, offering three-dimensional visualization and vascular information, has the advantage of identifying the presence of intraperitoneal or extraintestinal complications, such as abscesses and enterocutaneous and extraintestinal fistulas that may require surgical planning. On the other hand, cross-sectional imaging does not allow detection of subtle or advanced mucosal lesions. Follow-through barium study shows a long segment of the distal ileum characterized by multiple stenoses and sacculated prestenotic dilations due to the typical segmentary spreading of disease. At the barium study, a tight stricture of the distal ileum and irregularity of the cecal fundus are observed, suggestive of ileocecal Crohn disease. A spot view demonstrates a tiny fistulous tract between the terminal ileum and the right colon adjacent to the ileocecal valve, a common extramural bowel complication. The sonographic hallmark is bowel wall thickening that involves all layers of the affected intestinal tract, ranging from 5 to 20 mm. In most chronic lesions, the submucosal layer is typically thickened and hyperechoic, likely due to increased submucosal fat either in active or nonactive disease; such submucosal increased thickening and echogenicity produces the typical layered pattern of Crohn disease. The affected bowel shows decreased peristalsis and a narrowed lumen, and it is often surrounded by noncompressible swollen fatty tissue. Mesenteric lymph nodes may be markedly enlarged, and in many cases an abscess, fistula formation, or prestenotic dilatation can be diagnosed as well. With severe inflammation, the wall may appear diffusely hypoechoic with partial or total loss of layering due to transmural edema, with a central hyperechoic line that corresponds to the narrowed lumen. Peristalsis is reduced or absent, and the diseased segment is noncompressible and rigid, with a loss of haustra. However, the same finding of layering loss may be observed in the presence of diffuse wall fibrosis with nonactive disease. It decreases the diagnostic delay and prevents unnecessary surgical interventions. Ultrasound image shows a marked concentric thickening of the bowel wall and a narrowed lumen of the terminal ileum. Increased color Doppler signal suggests a high degree of inflammation of the bowel wall, as well as initial inflammatory involvement of the adjacent mesenteric fat. The contrast agent should provide a homogeneous luminal enhancement, high contrast between the lumen and the bowel wall, and minimal mucosal absorption, and lead to no artifact formation or significant adverse effects. However, using intraluminal positive contrast agents for bowel wall enhancement after intravenous administration of contrast material may obscure submucosal lesions. Negative intraluminal contrast agents (methylcellulose or water iso-osmolar solutions) can similarly help detect normal or pathologic bowel wall segments, with the advantage of better visualization of the wall contrast enhancement and submucosal lesions. The use of an intravenous contrast agent is extremely important for better visualization of the normal and inflamed bowel wall (3, 4). The computed tomographic image, on axial plane, shows a marked thickening of the wall of the ileal anastomotic loop, with a narrowed lumen and proliferation of perivisceral fat tissue. The diagnostic imaging protocol should include both T1 and T2-weighted sequences to detect and characterize intestinal lesions, with the acquisition of axial and coronal thin, contiguous images. Acquisition of coronal and axial images is obtained with a 4-mm section thickness and a field of view of at least 350350 mm to cover all the bowel loops, adding sagittal plane images if necessary for a complete evaluation of disease. Negative or biphasic contrast agents are more commonly used for evaluating small bowel diseases. Biphasic intraluminal contrast agents may produce either high or low signal, depending on the pulse sequence used; the more widely used have a water-like behavior, demonstrating low signal intensity on T1-weighted sequences and high signal intensity on T2-weighted sequences. To assess inflammatory lesion activity, T1-weighted spoiled gradient imaging, after intravenous administration of a gadolinium chelate, and T2-weighted fat-suppressed imaging are used.

These unstable injuries result in accelerated degenerative change and are an indication for urgent orthopedic referral diabetes type 2 new medication discount precose 50 mg line. Tibial plateau fractures usually occur in older patients with acute injuries blood glucose monitor optium xceed generic precose 25mg with visa, usually twisting injuries in falls but also in direct trauma diabetes test machine discount precose 25mg on line. These fractures may be radiographically occult with the only clue being a lipohemarthrosis diabetes symbol purchase 25mg precose. Indications for fracture repair include distraction of fracture fragments of greater than 5 mm or depression greater than 10 mm. Ankle and Foot Supination-adduction injuries result from an acute varus stress on the foot when weight bearing on the outside of the foot. The initial injury is to the lateral ligaments of the ankle, most commonly the anterior talofibular and calcaneofibular ligaments. Loss of lateral stability results in lateral translation of the tibia on the talus. The shearing forces can lead to an oblique or vertical fracture of the medial malleolus. Supination-external rotation of the ankle results from inward rotation of the leg while weight bearing on the outside of the foot. Deltoid ligament injuries may be subtle and stress views are warranted in the setting of a spiral fracture of the fibula at Fractures, Peripheral Skeleton. Figure 1 Coned in lateral view of the knee (a) demonstrates an arcuate fracture (arrow) through the apex of the fibula, usually associated with posterolateral corner injury. Fractures, Peripheral Skeleton 745 the level of the syndesmosis and soft tissue swelling over the medial malleolus. Pronation-external rotation occurs when inward rotation of the tibia takes place while weight bearing on the instep of the foot. This force initially places the deltoid ligament under tension and results in a ligamentous sprain or avulsion fracture. Fracture of the fibula 10 cm above the mortise usually follows, although fracture of the proximal fibula, a Maisonneuve fracture, may also occur in this setting. Proximal fibular fractures should be sought in the setting of widening of the medial joint space or widening of the distal tibiofibular syndesmoses over 5. These injuries may be subtle or temporarily reduce and the only clue to a proximal fibular fracture is medial malleolar swelling and an isolated posterior malleolus fracture. Pronation-abduction injuries result from a valgus stress on the ankle while weight bearing on the instep of the foot. The second stage of the injury is disruption of the distal tibiofibular syndesmosis, which may be accompanied by an avulsion fracture of the posterior malleolus. Continued force results in a characteristic oblique fibular fracture above the ankle mortise. Compression fractures of the calcaneus occur in the setting of axial loading and are frequently associated with vertebral compression fractures. Fracture extension into the posterior subtalar facet and depression of this joint should be carefully assessed. Two common locations for avulsion fractures of the calcaneus include the anterior process and anterolateral aspect of the calcaneus at the attachments of the bifurcate ligament and extensor digitorum brevis muscles, respectively. They are often radiographically occult and are best assessed with cross-sectional imaging. The most important injury involving the cuneiforms is the Lisfranc fracture-dislocation. The first and second metatarsals are aligned with the medial and middle cuneiforms, respectively. Associated dislocations may follow a homologous (second through fifth metatarsals laterally displaced) or divergent (additional medial displacement of the first metatarsal) pattern. Fractures of the metatarsals and phalanges are common and are often the result of direct trauma. Imaging Radiographs Plain radiographs are sufficient for evaluation of most extremity fractures. As a rule of thumb, two orthogonal views and an oblique view are considered the minimum necessary to assess for the presence or absence of a fracture. Fractures are most commonly seen on radiographs as an abnormal line of radiolucency. F Ultrasound Ultrasound is an excellent modality in acute trauma for assessing the integrity of ligaments and tendons.

Negative pressure ventilators, such as the iron lung, create a vacuum around the outside of the chest, causing the chest to expand and suck air into the lungs. Positive pressure ventilators, which have been available since the 1940s, work on the opposite principle, by blowing air directly into the lungs. Ventilators are invasive an air passage is made in the throat area, fitted with a device most people call a "trach. Positive pressure air is supplied to a mouthpiece from the same type of ventilator used with a trach. Candidates must have good swallowing function; they also need a full support network of pulmonary specialists. There are not many clinicians with expertise in the method, thus its availability is limited. Another breathing technique involves implantation of an electronic device in the chest to stimulate the phrenic nerve and send a regular signal to the diaphragm, causing it to contract and fill the lungs with air. The Avery has been implanted in over 2,000 patients, with about 600 in use now, some continuously for almost 40 years. The procedure involves surgery through the body or neck to locate the phrenic nerve on both sides of the body. A small radio receiver is also implanted in the chest cavity; this is activated by an external antenna taped to the body. Two electrodes are placed on each side of diaphragm muscle, with wires attached through the skin to a battery powered stimulator. Since breathing is shallower during sleep, any drop in volume can lead to trouble including retention of carbon dioxide, which causes headache. Others may wake up repeatedly during the night as the shallow breathing causes a sudden jolt. Broken sleep causes daytime sleepiness, lethargy, anxiety, irritability, confusion and physical problems such as poor appetite, nausea, increased heart rate and fatigue. Using a removable mask Paralysis Resource Guide 108 2 over the nose, the system delivers a pressurized breath of air into the lungs, then drops the pressure to allow an exhale. The most common use is for people with sleep apnea, characterized by snoring and lack of oxygen during sleep. Sleep apnea is linked to high blood pressure, stroke and cardiovascular disease, memory problems, weight gain, impotency and headaches. For reasons that are not completely clear, sleep apnea is significantly more common to people with spinal cord injuries, especially those with quadriplegia, among whom an estimated 25-40 percent have the condition. It may also be that certain medications (baclofen, for example, is known to slow down breathing) affect sleep patterns. People with higher cervical injuries who rely upon neck and upper chest muscles to help with breathing may be susceptible to sleep apnea because these muscles are inactive during deep sleep. Tracheostomy care: There are many potential complications related to tracheostomy tubes, including the inability to speak or swallow normally. Certain tracheostomy tubes are designed to direct air upward during exhalation and thus permit speech during regular, periodic intervals. The tube is a foreign body in the neck, and thus has the potential of introducing organisms that would ordinarily be stopped by natural defense mechanisms in the nose and mouth. Cleaning and dressing of the tracheostomy site daily is an important preventive measure. Weaning (removing ventilator support): In general, those with complete neurologic injuries at C2 and above have no diaphragmatic function and require a ventilator. Those with complete injuries at C3 or C4 may have diaphragmatic function and usually have the potential for weaning.

Initial evaluation should include blood pressure assessment and biochemical assessment of renal function including serum creatinine, creatinine clearance and 24 h urinary protein assessment. Much attention is paid currently to the workup of patients who present with hypertension in search of a treatable cause. Though 95% of cases are idiopathic, if a cause can be identified and treated the complications of hypertension such as stroke and renal failure can be reduced. Contrast has been infused into the ileal conduit through a Foley catheter inserted into the proximal portion of the conduit. Contrast is seen to reflux freely into the right ureter and collecting system of the right kidney (arrow). The condition is caused by a mechanical abnormality at the ureterovesical junction. The ectopic location of the ureter shortens the normal course of the ureter within the detrusor muscle. This leads to incompetence of the normal valve-like closure system when the intravesical pressure rises on filling and micturition. Symptoms are often non-specific and include a feeling of being generally unwell, tired, lack of energy, anorexia, nausea, vomiting and pyrexia. Some females may be asymptomatic and have incidental bacteria noted on urinalysis. With this examination, contrast is instilled into the bladder and the patient then micturates while the radiologist visualises the process with fluoroscopy. In the normal person, contrast (urine) should remain in the bladder during the full procedure and not reflux into the ureters. If reflux is present, its level of reflux is classified according to a designated grading system. Grade I: Urine refluxes into the ureter only with normal renal pelvis and calyces 2. The ureter appears mildly dilated and there is evidence of some blunting of the calyces 4. Evidence of moderate dilatation of the ureter and moderate blunting of the calyces 5. With direct radionuclide cystography, the bladder is infused with 500 mL of saline mixed with 99mTechnetium labelled sulphur colloid via a catheter. The bladder is filled and the patient subsequently micturates under direct visualisation of the gamma camera. Any nuclide appearing in the ureters and kidney is abnormal and diagnostic of reflux. With indirect radionuclide cystography, a standard renogram is initially performed. Twenty minutes following this, when the patient feels the need to micturate they are asked to do so in front of the gamma camera. R Ultrasound Ultrasound is an inexpensive, widely available technique that can be used to screen for reflux. Ultrasound permits assessment of renal size, shape, cortical abnormalities as well as ureteric abnormalities. With this method, a galactose suspension of fluid is instilled into the bladder and the presence of reflux is detected by continuous scanning. Advantages of ultrasound include the absence of ionising radiation as well as better anatomic resolution compared with radionuclide studies. Limitations included poor sensitivity at detecting grade 1 reflux as well as the length of time required for the procedure. Secondary changes include evidence of parenchymal scarring, calyceal clubbing, ureteric dilatation and mucosal striations.
