Contraindications to allergy symptoms vs cold order 10 mg cetirizine amex hepatic artery embolization include excessive tumour burden, persistently abnormal liver function and portal vein thrombosis. Hepatic artery embolization was first used for the treatment of neuroendocrine metastases in 1977. These patients had complete palliation of their symptoms during a follow-up of 6 months. This study demonstrated an 87% symptomatic response rate and a median response duration of 11 months; however, this was associated with a 9% mortality secondary to complications of embolization. As yet there is little evidence that hepatic artery embolization improves survival. In this study mean survival was prolonged by 2 years compared with that of historical controls. Cyanoacrylate is a low viscosity liquid that polymerizes on contact with blood or endothelium. The use of this mixture allows peripheral, complete and permanent arterial occlusion. Chemoembolization involves the use of ethiodized oil as a carrier for various cytotoxic drugs. The encapsulation of drugs in microcapsules capable of slow deterioration is also of interest. In addition to vascular occlusion, encapsulation allows the slow release of cytotoxic agents in direct proximity to Management of neuroendocrine tumours 261 tumour deposits. A number of authors have reported their experience of these techniques, although it is uncertain whether there is any advantage over embolization alone. However, the development of modern cryotherapy delivery systems, together with the introduction of intraoperative ultrasound, has allowed the application of cryotherapy techniques for the treatment of hepatic tumours. Hepatic cryotherapy involves the delivery of liquid nitrogen to the tip of relatively thin insulated probes. Intraoperative ultrasound guides probe placement and the monitoring of ice formation during the freezing process. Cryotherapy has been widely used for the treatment of primary90 and secondary hepatic tumours, predominately colorectal metastases. Four patients were symptomatic and three of these patients had elevated tumour markers. Patients with elevated preoperative markers showed a dramatic reduction in tumour markers following treatment. This group published their experience of a total of 13 patients with neuroendocrine hepatic metastases treated by hepatic cryotherapy. One patient died of bronchopneumonia 45 months following cryotherapy, but without evidence of tumour recurrence. One patient developed a recurrence in one of seven liver metastases and this was subsequently treated by hepatic resection 13 months following hepatic cryotherapy. This patient went on to develop a sacral recurrence of his rectal carcinoid which was also resected. However, the remaining nine patients were alive with no evidence of recurrent disease. Seven of these 13 patients had had symptoms related to ectopic hormone production. In all patients symptoms were significantly alleviated and postoperatively five patients were completely asymptomatic. In this series, two patients with carcinoid metastases developed a coagulopathy postoperatively and required further laparotomy together with the replacement of clotting factors. All patients had advanced disease and cryosurgery was considered palliative as evidenced by residual liver disease, lymph node involvement, residual primary disease or unknown primary site. Recurrent symptoms following cryotherapy were effectively palliated in three patients using somatostatin and in five patients by chemotherapy. Cryotherapy has the advantage of being able to treat bilobar disease and lesions close to major blood vessels. This treatment appears to be safe and to provide good palliation of symptoms related to ectopic hormone production. In some patients it appears that long Surgical Management of hepatobiliary and pancreatic disorders 262 term disease-free survival may be obtained. However, given the long natural history of neuroendocrine tumours and the relatively short follow-up of patients treated by hepatic cryotherapy, evidence for prolonged survival is as yet unavailable. However, it rapidly became clear that this was associated with high rates of disease recurrence. The results of hepatic transplantation for metastatic tumours are particularly poor. The two largest series describe 2-year survival rates between 14% and 19%, with 5-year survival rates not exceeding 5%. In 1989, the Pittsburgh group reported a series of five patients with neuroendocrine hepatic metastases, three of whom were alive at 7, 16 and 34 months following surgery. Five patients had died, four from recurrent disease and one from chronic rejection. In this study, tumour recurrence for patients with carcinoid tumours was more frequent. However, it was thought that this may have reflected the fact that transplantation was carried out later in the course of the disease process in carcinoid patients or due to differential effects of immunosuppression on tumour growth. One patient underwent upper abdominal exenteration with liver replacement for a large pancreatic tumour. With this exception, all patients had previously undergone resection of the primary tumour. In this series, despite extensive preoperative imaging, extrahepatic tumour was found in four patients and this was resected. Two patients died as a result of portal vein thrombosis and one patient died at day 7 from overwhelming septicaemia. Of the remaining patients, one patient died at 17 months as a result of bone and liver recurrence. Three patients were alive at 15, 24 and 62 months, but the longest survivor had developed bone and liver metastases. The authors have recommended that transplantation should only be offered to patients with symptomatic disease that has failed to respond to all other therapies. In addition, they conclude that the finding of extrahepatic disease at Management of neuroendocrine tumours 263 laparotomy should probably result in the abandoning of the transplant procedure. Two patients died from tumour recurrence, one at 6 months, the other at 5 years post-transplantation. Four of these patients were disease-free 2, 57, 58 and 103 months post-transplantation. All patients experienced good symptomatic relief and postoperative hormone levels were within normal ranges. The largest series of patients undergoing liver transplantation for the treatment of neuroendocrine hepatic metastases comes from France. Twelve patients subsequently died; four of these deaths were due to delayed technical or other non-tumour complications. All seven patients that had undergone upper abdominal exenteration died from immediate or delayed surgical complications. At the time of their publication, 13 patients were alive and in eight of these there was no evidence of recurrent disease. However, the survival rate for carcinoid tumours was significantly higher with a 5-year survival rate of 69%. This reflected a lower postoperative mortality for patients with carcinoid tumours and the fact that disease recurrence was more compatible with long-term survival. Overall survival figures are not dissimilar from the 25 to 35% 5-year survival reported for non-transplant treatments. There is now a broad consensus regarding the indications and timing of liver transplantation for patients with neuroendocrine hepatic metastases. This allows a full laparotomy to be performed and extrahepatic disease may be identified at this time. Inevitably some patients may present later with extrahepatic disease and then no longer be candidates for transplantation. However, transplantation continues to be associated with high surgical mortality and many patients can be maintained on medical therapy for a prolonged period of time.

The roof is formed by the super cial fascia allergy symptoms juniper cetirizine 5 mg mastercard, containing the super cial inguinal lymph nodes and the great saphenous vein with its tribu taries, and the deep fascia (fascia lata), which is pierced by the saphenous vein at the saphenous opening. The fascia lata the deep fascia of the thigh, or fascia lata, extends downwards to Fig. The fascia of the thigh is particularly dense laterally (the iliotibial tract), where it receives tensor fasciae latae, and posteriorly, where the greater part of gluteus maximus is inserted into it. This is derived from the extraperitoneal intra-abdominal fascia, its anterior wall arising from the transversalis fascia and its posterior wall from the fascia covering the iliacus. The medial part of the femoral sheath contains a small, almost vertically placed gap, the femoral canal, which is about 0. The canal has two functions: rst, as a dead space for expansion of the distended femoral vein and, second, as a lymphatic pathway from the lower limb to the external iliac nodes. The safe alternative is to divide the inguinal ligament, which can then be repaired. The lymph nodes of the groin and the lymphatic drainage of the lower limb the lymph nodes of the groin are arranged in a super cial and a deep group. The super cial nodes lie in two chains, a longitudinal chain along the great saphenous vein, receiving the bulk of the super cial lymph drainage of the lower limb, and a horizontal chain, just distal to the inguinal ligament. These horizontal nodes receive lymphatics from the skin and super cial tissues of: 1 the lower trunk and back, below the level of the umbilicus; 2 the buttock; 3 the perineum, scrotum and penis (or lower vagina and vulva) and the anus below its mucocutaneous junction. In addition, some lymphatics drain via the round ligament to these nodes from the fundus of the uterus. In addition, a small area of skin over the heel and lateral side of the foot drains by lymphatics along the small saphenous vein to nodes in the popliteal fossa and then, along the femoral vessels, directly to the deep nodes at the groin. The deep groin nodes drain to the external iliac nodes by lymphat ics which travel partly in front of the femoral artery and vein and partly through the femoral canal. The inguinal ligament is detached so that, in addition, an extraperitoneal removal of the external iliac nodes can be carried out. The contents of the canal are the femoral artery, the femoral vein (which lies behind the artery), the saphenous nerve and, in its upper part, the nerve to vastus medialis from the femoral nerve. The common peroneal nerve passes out of the fossa along the medial border of the biceps tendon; the tibial nerve is rst lateral to the popliteal vessels and then crosses super cially to these vessels to lie on their medial side. As well as these important structures, the fossa contains fat and the popliteal lymph nodes. The arteries of the lower limb Femoral artery the femoral artery is the distal continuation of the external iliac artery beyond the inguinal ligament. Branches In the groin, the femoral artery gives off: 1 the super cial circum ex iliac artery; 2 the super cial epigastric artery; 3 the super cial external pudendal artery. It is conventional to| | call the femoral artery above this branch the common femoral, and below it, the super cial femoral artery. These are important both as the source of blood supply to the great muscles of the thigh and as collateral channels which link the rich arterial anastomoses around the hip and the knee. The femoral artery in the upper 4in (10 cm) of its course lies in the| | femoral triangle where it is quite super cial and, in consequence, easily injured. Collateral circulation is maintained via anastomoses between the branches of profunda femoris and the popliteal artery. If arteriography demonstrates a patent arterial tree distal to the block, it is possible to bypass the occluded segment by means of a graft between the common femoral and popliteal arteries. Popliteal artery the popliteal artery continues on from the femoral artery at the adductor hiatus and terminates at the lower border of the popliteus muscle. Pressure of the aneurysm on the adjacent vein may cause venous thrombosis and peripheral oedema; pressure on the tibial nerve may cause severe pain in the leg. It can also be exposed by a medial approach, which divides the insertion of adductor magnus and detaches the origin of the medial head of gastrocnemius from the tibia. Posterior tibial artery the posterior tibial artery is the larger of the terminal branches of the popliteal artery. It descends deep to soleus, where it can be exposed by splitting gastrocnemius and soleus in the midline, then becomes super cial in the lower third of the leg and passes behind the medial malleolus between the tendons of exor digitorum longus and exor hallucis longus. Anterior tibial artery the anterior tibial artery arises at the bifurcation of the popliteal artery. At rst deeply buried, it becomes super cial just above the ankle between the tendons of extensor hallucis longus and tibialis anterior, being crossed super cially by the former immediately proximal to the line of the ankle joint. Dorsalis pedis itself plunges between the 1st and 2nd metatarsals the veins of the lower limb 267 to join the lateral plantar artery in the formation of the plantar arch, from which branches run forwards to supply the plantar aspects of the toes. One or more branches run upwards and medially from it to join the great saphenous vein. The great (long) saphenous vein drains the medial part of the venous plexus on the dorsum of the foot and passes upwards immedi ately in front of the medial malleolus (Fig. The great saphenous vein is joined by one or more branches from the small saphenous, and by the lateral accessory vein which usually enters the main vein at the mid-thigh, although it may not do so until the saphenous opening is reached. At the groin a number of tributaries from the lower abdominal wall, thigh and scrotum enter the great saphenous vein; these tribu taries are variable in number and arrangement but usually comprise (Fig. The super cial epigastric vein communicates with the lateral tho racic tributary of the axillary vein via the thoracoepigastric vein. This dilates (and may become readily visible coursing over the trunk), fol lowing obstruction of the inferior vena cava. Knowledge that a vein must be present at this site, even if not visible in an obese or collapsed patient, may be life-saving when urgent transfusion is requred. There are two exceptions: the obturator nerve appears at the medial border of psoas tendon, and the genitofemoral nerve emerges on the anterior aspect of the muscle. The principal branches of the plexus are the femoral nerve and the obturator nerve. This arises directly from the lumbar plexus and enters the thigh usually by passing deep to the inguinal ligament. This is relieved by dividing the deeper fasciculus of the inguinal ligament where the nerve passes over it. This can be performed through a midline lower abdominal incision exposing the nerve trunk extraperitoneally on each side as it passes towards the obturator foramen. Pressure of a strangulated obturator hernia upon the nerve causes referred pain in its area of cutaneous distribution, so that intestinal obstruction associated with pain along the medial side of the thigh should suggest this diagnosis. Note that L4 is shared by both plexuses, a branch from it joining L5 to form the lumbosacral trunk which carries its contribution to the sacral plexus. It has a complex course, passing from the pelvis, brie y through the gluteal region, along the side-wall of the ischiorectal fossa and through the deep perineal pouch to end by supplying the skin of the external genitalia (Fig.

A suprapubic catheter is not indicated in the setting of a normal urethrogram allergy shots dallas cheap 10 mg cetirizine mastercard, but is indicated if there is a displaced urethral injury. All such injuries require repair once the diagnosis is made and the patient has been stabilized. The treatment of an acute traumatic diaphragmatic injury is via an abdominal approach (ie, an exploratory laparotomy or diagnostic laparoscopy) so as to rule out associated intra-abdominal injuries. Missed injuries lead to problems with herniation and bowel strangulation with sufficient frequency whose repair should not be delayed. The treatment of chronic traumatic diaphragmatic injury, which may occur due to a missed diagnosis, is either via a thoracic or an abdominal approach. Traumatic injuries to the diaphragm are associated with both blunt and penetrating trauma. The spleen, kidneys, intestines, and liver are the most frequently injured abdominal organs in blunt trauma; the diaphragm is the least. Therefore, even the presence of a grade V injury (completely shattered spleen or hilar vascular injury) does not preclude a trial of nonoperative therapy. Patients who are hemodynamically unstable or who demonstrate clinical deterioration should undergo exploratory laparotomy. However, a normal chest x-ray does not rule out a diagnosis of a thoracic great vessel injury. Traumatic aortic injuries are deceleration injuries because of differential forces to the fixed and mobile parts of the thoracic aorta; most aortic injuries are located near the ligamentum arteriosus. In patients with cervical or thoracic injuries, loss of sympathetic regulation results in loss of vasomotor tone and hypotension. Patients with neurogenic shock are warm and pink, as opposed to patients who are hypovolemic, and who are cold and clammy. Because of loss of the reflexive tachycardic response to hypotension, these patients are usually also bradycardic. Treatment is with fluid resuscitation initially and vasoconstrictors after the intravascular volume have been restored. Compartment syndrome results in increased peak airway pressures, decreased venous return and decreased cardiac output, increased systemic vascular resistance, decreased renal blood flow and glomerular filtration rate, and decreased portal venous flow with decreased liver function. Because of decreased venous return, the intracranial pressure increases and cerebral perfusion pressure decreases. If the patient does not respond, the bolus should be repeated and then blood transfusion initiated. In most cases of trauma-related cardiac tamponade, patients need surgical exploration to relieve the tamponade and repair the wound in the heart that caused it. It is advisable to perform pericardiocentesis or subxiphoid pericardial drainage under local anesthesia before anesthetic induction in these unstable patients. Cardiac tamponade is a reversible cause of shock that occurs when fluid or blood accumulates between the pericardium and the heart. If the pericardial fluid develops under significant pressure, filling of the heart cannot occur during diastole, and the amount of blood ejected during systole decreases. Cardiac tamponade is mainly seen in patients with penetrating trauma in proximity to the sternum. The diagnosis should be considered in patients with pulsus paradoxus, which is a greater than 10-mm Hg fall in arterial systolic blood pressure with inspiration. Echocardiography is the preferred diagnostic tool for identification of fluid or blood in the pericardium. It occurs more frequently after blunt chest trauma and radiologic findings may not be present on admission, developing several hours after the initial injury. The management of pulmonary contusion is almost entirely supportive with maintenance of good oxygenation and adequate pulmonary toilette. Patients with persistent low PaO levels who do not2 respond to supplemental oxygen, pulmonary toilette, and pain control should be intubated and mechanically ventilated. The findings of rib fractures and an underlying well-defined infiltrate are less supportive of the diagnosis of pulmonary embolus, pneumonia, myocardial infarction, or cardiac tamponade. Blunt injuries to the tracheobronchial tree occur after direct compression of the airway with a closed glottis or after decelerating injuries causing partial or complete avulsion of the right mainstem bronchus from the carina or tracheal lacerations. Patients may present with pneumothorax, subcutaneous emphysema, pneumomediastinum, hemoptysis, and respiratory distress. Small injuries usually heal spontaneously with supportive care but are associated with late complications such as stricture formation at the site of injury and recurrent pulmonary infection. The patient does not have physical examination findings of a sucking chest wound to support an open pneumothorax. A tension pneumothorax would not involve air in the subcutaneous space or mediastinum. An esophageal injury would not present with the large amount of emphysema or respiratory distress. Exploratory laparotomy is not indicated in solid-organ injury (liver, spleen, kidney) in patients with hemodynamic stability and no evidence of contrast extravasation. This is followed by instillation of 30 mL of water-soluble contrast and a plain radiograph is obtained. No attempt at insertion of a bladder catheter should be made until a negative retrograde urethrogram is obtained to avoid further damaging a urethral injury. An intravenous pyelogram is obtained to evaluate the kidneys, ureter, and bladder. Respiratory distress may ensue when the noncompliant flail segment interferes with generation of adequate positive and negative intrathoracic pressure needed to move air through the trachea. In addition, a blow sufficiently violent to cause a flail chest may also contuse the underlying pulmonary parenchyma, which compounds the respiratory distress. Treatment consists of pain control and treatment of the underlying pulmonary contusion. Airway obstruction denotes partial or complete occlusion of the tracheobronchial tree by foreign bodies, secretions, or crush injuries of the upper respiratory tract. Patients may present with symptoms ranging from cough and mild dyspnea to stridor and hypoxic cardiac arrest. An initial effort should be made to digitally clear the airway and to suction visible secretions; in selected stable patients, fiberoptic endoscopy may be employed to determine the cause of obstruction and to retrieve foreign objects. Unstable patients whose airways cannot be quickly reestablished by clearing the oropharynx must be intubated. An endotracheal intubation may be attempted, but cricothyroidotomy is indicated in the presence of proximal obstruction or severe maxillofacial trauma. Blunt or penetrating trauma to the pericardium and heart will result in pericardial tamponade when fluid pressure in the pericardial space exceeds central venous pressure and thus prevents venous return to the heart. A subxiphoid, supradiaphragmatic incision and creation of a pericardial window, ideally performed in the operating room, provides a rapid, safe means of confirming the diagnosis of tamponade and of relieving venous obstruction. If bleeding is encountered on opening the pericardial window, a sternotomy should be performed. Tension pneumothorax occurs when a laceration of the visceral pulmonary pleura acts as a one-way valve that allows air to enter the pleural space from an underlying parenchymal injury but not to escape. Increasing intrapleural pressure causes collapse of the ipsilateral lung, compression of the contralateral lung due to mediastinal shift toward the opposite hemithorax, and diminished venous return. Open pneumothorax occurs when a traumatic defect in the chest wall permits free communication of the pleural space with atmospheric pressure. If the defect is larger than two-thirds of the tracheal diameter, respiratory efforts will move air in and out through the defect in the chest wall rather than through the trachea. The immediate treatment is placement of an occlusive dressing over the defect; subsequent interventions include placement of a thoracostomy tube (preferably through a separate incision), formal closure of the chest wall, and ventilatory assistance if needed.

A balance should be achieved in terms of applying pressure with the probe: on the one hand, the greater the pressure, the better the vessel is sealed, while on the other hand, greater pressure also increases coagulation depth and thus perforation risk (32) Fig. In one study (34) the risk of rebleeding was 9% in the first year, 10% in the second year, 19% in the third year, and 25% in the fourth year. Diverticular bleeding characteristically occurs when a vessel ruptures either near the tip of the diverticulum or in the diverticulum neck on the side opposite the mesentery. The blood vessels near the diverticulum are located very close to the surface, separated only by a thin layer of mucosa from the lumen. It has often been suggested that they are caused ing and publications on the principles of endoscopic therapy by mechanical lesions from coproliths or digestive material, tend to have a casuistic character. Studies have reported on the though there is lacking evidence to support this explanation. As and fibrin glue, as well as thermocoagulation by means of laser, early as 1990, Wilson et al. An interesting report anti-inflammatory drugs could promote myriad complications has also been written on mechanical hemostasis of diverticular related to diverticular disease of the colon. In the western hemisphere, diverticula appear mostly in the left hemicolon, especially in the sigmoid colon (up to 90%). Endoscopic therapy Yet, for unexplained reasons, it is diverticula in the right hemi As a rule, the methods used for achieving endoscopic he colon that have a greater bleeding tendency. The size of suggests that mucosal lesions induced by use of nonsteroidal diverticula and exact localization of bleeding relative to anti-inflammatory drugs occur more frequently in the right the diverticulum opening are important factors. If the diverticulum itself is the source of bleeding, epine phrine solution (1:10000) can be injected into the sub mucosa of the four quadrants of the diverticulum neck. In addition to the vasoconstrictive effect of epinephrine, compression of the supplying vessel also assists in achieving hemostasis. Alternatively, if the vessel or bleeding source is localized in a wider diverticulum, epinephrine injection can be made directly into the mu cosa of the tip of the diverticulum, which occasionally elevates the bleeding source, enabling better visualiza tion of the source. In addition to numerous angio dilated veins resulting from the dysplasias in the ascending colon, arteriovenous shunt.

The last major system to evaluate in the chest radiograph aside from a couple of other tips is the bony thorax. I tell my students that after looking at chest radiographs for 30 years I can usually see everything at once but that it took years of practice and looking at every bone before I felt comfortable with it. I still carefully examine every bone, (now using a magnifying glass) if looking for fractures or metastatic pathology. I further inform them that to reach a level of competence, the practice of scrutinizing each bone is an absolute necessity, and that to program that computer between their ears to easily spot abnormalities of the bony thorax can not be done in a short period of time. Just to illustrate the point, see if you can spot the bony abnormalities in the following figures before reading the answers under each picture. See if you can spot any bony abnormalities (subtle) before referring to the sketch below. The negative study of an aortic arch angiogram in this same patient shows the coarctation (white arrow) in Figure # 63b (below). The next case (below) demonstrates another bony abnormality that may be difficult to see for the inexperienced eye. Tomograms of this area shown in figures 66 and 67 on the next page demonstrate the bone destruction caused by metastatic carcinoma. This sounds like a lot to consider, but in actuality the student will quickly make a decision as to whether or not the pattern is normal. If it is not, one then has to decide why not, and also if the pattern is specific or non-specific. The chest film is included for two reasons: 1) Many chest conditions such as pneumonia or pleural effusions can present as abdominal pain and 2) It gives us a chance to look at the diaphragm and for free air. The upright or decubitus view lets us look for localizing signs such as air fluid levels or isolated and dilated loops of bowel. Sometimes we are only given a single view to interpret, especially when the film comes from an outside source (St. If one observes gas filled, dilated loops of bowel, we must then decide whether or not we are dealing with an adynamic ileus, an obstructive ileus, a localizing phenomenon such as might occur with appendicitis, cholecystitis or pancreatitis (sentinel loop), or a natural finding as occurs with aerophagia in a crying child or air forced into the gut during general anesthesia. It is also important to recognize whether or not the gas is in large or small bowel. That is not always possible, but one of the things that helps tell the difference is to see if the haustral markings extend all the way across the loop or only part way. Colon haustral markings typically traverse only part of the way across the loop, whereas small bowel haustra usually extend the full diameter of the loop. Obstructive ileus is usually oriented in an up and down or vertical pattern, whereas paralytic ileus is usually oriented in a transverse plane. Yellow arrows point to multiple air-fluid levels in this patient with obstructive ileus, the red curved arrows show the haustral markings extend the entire diameter of the bowel, thus identifying it as small intestine. Note there is very little gas in the colon, that the small bowel is markedly dilated and that these loops are vertically oriented. Red arrows point to haustra that do not traverse the diameter of the bowel indicating the dilated loops of this portion are likely colon. Note that both small and large bowel are dilated and that the loops have a relatively horizontal 54 orientation. This patient has a paralytic or non-obstructive ileus, with gas extending all the way to the rectum. Localization of gas in the intestine in a dilated segment or region occurs with a confined inflammatory process such as appendicitis (right lower quadrant), cholecystitis (right upper quadrant) or pancreatitis (sentinel loop). Gas may also appear in bile ducts or other extra-luminal locations under certain conditions. These radiographic findings are not specific, but do tend to localize an inflammatory process, and appendicitis should be included in the differential diagnosis. The next figure (#71) is a coned-down view of the right lower quadrant in this same patient. Black arrows point to two oval shaped calcifications in the right lower quadrant consistent with fecaliths of the appendix. Remember that abnormal calcifications are the fifth item on your abdominal film checklist! Yellow arrow indicates gas in the biliary ducts system, which occurred after gallstone passage in this patient. Free air in the abdomen can be localized under the diaphragm or in the flank in viscus perforations as seen in upright chest films or decubitus views respectively. It is important to know the history when calling free air since it is to be expected after abdominal surgery or intraperitoneal endoscopy. Also occasionally air can be discovered superimposed between the liver and diaphragm that is not extraluminal but instead within an inter positioned loop of bowel. When that occurs it may be necessary to obtain additional imaging to exclude a perforated hollow viscus. Yellow arrow points to the anterior leaf of the right hemi diaphragm, which has an eventration. Free air would layer out and since haustral markings are evident, the diagnosis of superimpositioned bowel between diaphragm and the dome of the liver can be made with confidence, at least in this case. Yellow arrow points to an abnormal accumulation of gas representing free air under the diaphragm in this patient with a perforated duodenal ulcer. Image courtesy of Netmedicine Medical Photographic Library via the Internet 57 Diffuse free air in the peritoneal cavity outlines the peritoneal reflections if the film is a flat plate only and is often said to give the appearance of a football effect if the pneumoperitoneum is not under tension. Although the football sign of free air is not entirely rare, it is not common either since most cases of pneumoperitoneum are diagnosed by an upright film of the chest or a lateral decubitus film of the abdomen. Figure 75 shows a pneumoperitoneum under tension in an infant with a perforated hollow viscus. Abdominal organs are compressed by free air under tension in this infant with a perforated gut. Gas patterns in the abdomen may offer specific signs to the astute clinician/radiologist too. It occurs when the leading edge of the intussusceptum projects into a pocket of gas as seen in figure 76. Another sign associated with intussuception is not really part of the gas pattern, but can be recognized if you are clinically suspicious and look for it. It is called a target sign and is the result of layers of peritoneal fat surrounding and within the intussusepted bowel, which is water density. Red arrow points to a classic crescent sign in a child with ileocolic intussusception. This patient also has a crescent sign that is obscured by adjacent bowel gas (yellow arrow). If, for example, the patient is guarding the right side of the abdomen as occurs with acute appendicitis or cholecystitis, the right psoas muscle will be contracted and thus not as sharply outlined as the left. In cases of retroperitoneal hemorrhage or retroperitoneal fibrosis, the psoas shadows may disappear altogether. In this case retro peritoneal hemorrhage (water density blood) silhouettes out the right psoas margin.

A 20-year-old acne medicine that millions of American teens are, no doubt, taking every day has been linked to a stunning array of negative psychiatric conditions including suicide, depression, psychosis, violent and aggressive behaviors, mood swings, emotional instability, paranoia and changes in personality. This makes one wonder if any drug, no matter how commonly prescribed is even remotely safe. With the enormous variety of drugs available today, many doctors no longer have the time to study the side effects of each drug they prescribe, and most patients never read the list of side effects that accompanies the drug. Also, few patients read the small printed contraindications or ask their doctor about the possible dangers of the drugs. One report on a survey published in a 1996 issue of the British Medical Journal found that less than two-thirds of patients recalled receiving any advice from their doctors on potential side effects. Although the doctor has a moral as well as a legal obligation to inform the patient about the risks of treatment, in most cases this important step is omitted. The drug company is legally protected as long as the side effects and contra-indications are listed. Read Side-Effect Labels to Save Your Life Side effects arising from the use of common pharmaceutical drugs can develop into some of the most grotesque symptoms imaginable. Before you start taking common prescription drugs, you may need to inform yourself about this often-fatal reaction. When your body starts fighting the drug, it will go into an extreme inflammatory response that causes your skin to die and literally burn away. This side effect can occur with any age group, from infants and teens to the elderly. Those who survive the ordeal are scarred for life, often to a 45 A new study by the Tel Aviv University in Israel and a second one by the University of Miami concluded that ginger extract (255 mg per day for 6 or more weeks) may be optimal for the treatment of osteoarthritis. As the number of people taking these drugs rises, the number of victims increases. They are also the most likely group to be prescribed a class of mind regulating drugs called atypical antipsychotics, not to be confused with antidepressants. The harmful side effects they cause include obesity, blood lipid imbalances and adult-onset (Type 2) diabetes. All of these conditions clearly increase the chance of developing heart disease or lead to a greater risk of suffering a heart attack or stroke. In a recent issue of Diabetes Care, the American Diabetes Association, the American Psychiatric Association, the American Association of Clinical Endocrinologists, and some other associations all joined forces to warn about this class of drugs. The reason for this unprecedented move is that the companies which produce these drugs have refused to list their side effects on package labels out of fear that no one will be willing to take the drugs. Scandalous Drug Business Naprosyn is a common drug of American origin used for treating arthritis. Over one million American children, whose behavior is considered aberrant, receive psycho-pharmaceutical drugs, although not a single diagnostic technique exists to determine whether a child suffers from one of the nearly two dozen symptoms related to emotional tension. The children show signs of retarded growth, develop high blood pressure, nervousness, sleeplessness and turn excessively passive and lethargic. They become depressed and apathetic, a common symptom among those who took the drugs. Making changes in their diets, such as eliminating stimulating foods like sugar, chocolate and other unnatural sweets, chips, breakfast cereals and basically all junk food, can help most of these children. Many children are highly allergic to artificial colorings and preservatives, soft drinks, packaged fruit juices, and foremost of all, artificial sweeteners that may cause brain damage. As discussed previously, artificial sweeteners are found in most unnatural, sweet tasting foods and drinks. The Journal of the American Medical Association reported on November 3, 1975, that the results of only one-third of all clinical tests could be considered reliable. Therefore, at a time when most drugs are entering the market without scientific backing and justification, both physicians and patients ought to be vigilant and cautious about their use of drugs. If you want to know more about a drug, read the list of side effects accompanying the drug or consult the drug advisory board in your area (if available). Most medical doctors can only pass on the information they receive from the drug manufacturers. The whole drug side effect issue is complicated by the fact that drug reactions are only rarely reported by general practitioners. The French research revealed that only one out of 24, 433 adverse reactions is reported to the various drug monitoring agencies. All drugs are poisonous, and even if they happen to have a few beneficial side effects, in the majority of cases these do not warrant their use. Three out of four physicians fail to tell their patients about the toxic side effects of the prescription drugs they recommend. However, they obviously have the time to treat them during repeat visits for the diseases that result from the side effects of their prescriptions. Since the new drug scandals that occurred in 2004-05, this figure is quite likely to be 10 times as high. One severe adverse reaction, discovered later, was the potentially fatal condition known as rhabdomyolysis, in which destruction of muscle tissue occurs. The Contraceptive Pill: Catastrophic Risks In the United States alone, about 15 million women are taking the contraceptive pill. The Pill seems to be the easiest method of preventing an unwanted pregnancy, but it is also one of the most risky ones. Although natural methods of contraception have at least the same success rate and are a fraction of the cost or free, they are rarely publicized. Women taking the Pill who are between 30 and 40 have a three times higher risk of dying from a heart attack than women of the same age group who are non-users. Women who are over forty and still using the contraceptive pill have a six times higher risk of developing high blood pressure, a four times higher risk of having a stroke, and a five times higher risk of developing thrombosis and embolism, a condition where a blood clot may form and then lodge in an artery close to the heart. A four-year study of the Pill, carried out by the Imperial Cancer Research Fund in Oxford, England, reanalyzed epidemiological evidence on the Pill from more than 150, 000 women. The results show that all users face an increased risk of breast cancer, even for up to 10 years after they stop taking it. According to the study, published in 1996 in the Lancet, women on the Pill faced a 25 percent increase in the risk of breast cancer, and that risk was still 16 percent for up to five years after the medication was discontinued.
