Attempt to listen to fetal heart tones – 4 o’clock position, about 2” from mother umbilicus Page 287 of 385 D. Commotio cordis – sudden impact of blunt force to the chest resulting in cardiac dysfunction, even death 4. Risk is high for young and elderly, patients who can not generate heat (diseases and medications) c. Continued drops in temperature causes hypothalamic center to stimulate shriving Page 294 of 385. Many toxins cause the patients cells to release bradykinins, histamines, and serotonin c. Looking a trauma scene and attempting to determine what injuries might have resulted 2. Typically a patient considered to have “multi-trauma” has more than one major system or organ involved a. Consider use of tourniquets in emergent, hostile or multiple patient situations where bleeding is considerable 3. Early notification of hospital resources is essential once rapidly leaving the scene f. Be suspicious at trauma scenes, sometimes an obvious injury is not the critical cause one the potential for harm. Blast waves when the victim is close to the blast cause disruption of major blood vessels, rupture of major organs, and lethal cardiac disturbances b. Bleeding Related to Pregnancy: pathophysiology, assessment, complications, management 1. Neonatal mortality risk can be determined via graphs based on birth weight and gestational age b. Transport consideration transport to a facility with special services for low birth weight newborns g. Morbidity/ mortality represent relative medical emergencies as they are usually a sign of an underlying abnormality c. Risk factors prolonged and frequent multiple seizures may result in metabolic changes and cardiopulmonary difficulties 2. Morbidity/ mortality infants may die of cold exposure at temperatures adults find comfortable c. Pathophysiology Increased surface-to-volume relation makes newborns extremely sensitive to environmental conditions, especially when wet after delivery a.

Bulging fontanelle in a ill-appearing non-crying infant suggests increased intracranial pressure ii. In children younger than 10 years, narrowest part of the airway is below the vocal cords at the non-distensible cricoid cartilage 7. The epiglottis in infants and toddlers is long, floppy, narrow, and extends at a 45-degree angle into airway 9. Actually lifting the large, floppy epiglottis with the end of a straight laryngoscope blade will help expose the vocal cords iv. Because in children younger than 10 years, the narrowest part of the airway is below the vocal cords, uncuffed tubes are used v. The elastic thorax may result in significant underlying organ injury despite a fairly normal appearing external exam d. Lungs more prone to pneumothorax from excessive pressures while bag-mask ventilating f. Mobility of mediastinal structures makes children more sensitive to tension pneumothorax and flail chest g. Seemingly insignificant forces can cause serious internal injury; therefore abdominal pain after trauma should be taken seriously b. Hypothermia can limit resuscitative efforts and interfere with the body’s ability to clot properly G. Err on using a larger bag for ventilating the pediatric patient; regardless of the size of the bag used for ventilation, one should only use enough force to make the chest rise slightly to limit pneumothorax Page 328 of 385 d.

Therefore papillectomy (ampullectomy) should perform only by well-trained and experienced endoscopists 2mg leukeran visa. The incidence and severity of this complication can be significantly reduced by prophylactic pancreatic duct stenting (Wong discount leukeran 2 mg without prescription, 2004) cheap generic leukeran uk. Pancreatitis caused by stenosis of the pancreatic duct orifice can also be a late complication after papillectomy (Norton et al. Biliary sphincterotomy itself is not associated with an increased risk of pancreatitis. Currently the use of pure cut current is advisable, because it causes less tissue injury and edema than coagulation current. On the contrary to biliary sphincterotomy balloon dilatation of the intact biliary sphincter has been associated with a high incidence of pancreatitis, therefore its use is not advisable in the presence of patient-related risk factors, especially in patients with sphincter of Oddi hypertension. Large diameter biliary stent without sphincterotomy can also induce pancreatitis due to compression of the pancreatic sphincter (Tarnasky et al. Sphincter of Oddi manometry using standard perfusion catheter is associated with a substantial incidence of pancreatitis. The risk can be significantly reduced by using modified triple lumen catheter with simultaneous aspiration or by using a microtransducer catheter. What other procedure risk factors concerns, pancreatic brush cytology can cause pancreatitis due to edema in consequence of mechanical trauma of the pancreatic duct. Endoscopist’s inexperience and trainee participation may be associated with a higher incidence as it was shown in some of the studies, while others could not confirm it. Sofuni et al (2007) found significant benefit of stent placement only in patients at high risk for pancreatitis, and it seems to be not cost effective in patients at average risk (Das A et al. Stents of 3-Fr and 5-Fr in diameter proved to be similarly effective, but the insertion of 5-Fr stents seems to be easier and faster (Zolotarevsky et al. Pancreatic stent without internal flanges the stent migrates spontaneously into the duodenum within two weeks in most of the cases. Within 5 to 10 days after the stent insertion an X-ray control and, when the stent is in place yet, endoscopic stent removal is recommended because of the risk of stent-induced damage to the pancreatic duct. Adverse events including pancreatitis following stenting of the main pancreatic duct occur in 4. In patients with difficult bile duct cannulation successful biliary cannulation can be achieved by pancreatic guide wire-assisted technique in more than 70% of the cases (Dumonceau et al. If this method is used, a pancreatic stent should be placed for prophylaxis of pancreatitis (Fig 4. For the same reason pancreatic stenting can be useful also in cases in which biliary cannulation remains unsuccessful. This method may namely diminish traumatic injury to the pancreatic duct and hydrostatic pressure increase associated with injection of contrast material. Chemoprevention studies have targeted the following mechanism of action: reduction of pancreatic secretion, prevention of intra-acinar trypsinogen activation, interruption of inflammatory cascade, relaxation of sphincter of Oddi, and prevention of infection. The majority of the investigated pharmacological agents appeared promising in initial randomised single-centre clinical studies however, conflicting results were obtained from larger multi-centre trials (Table 3. Drug Efficacy Somatostatin Conflicting data Octreotide Conflicting data Gabexate mesilate Conflicting data Ulanistatin Conflicting data Nitroglycerin Conflicting data Nifedipin No Lidocain spray No Epinephrine spray No Botulinum toxin intrapapillary No Ceftazidime Need for more trials N-acethylcysteine No Beta-carotene No Allopurinol Conflicting data Glucocorticoids No Pentoxifylline No Semapimod No Acethylhydrolase No Indomethacin Yes, but need for more trials Diclofenac Yes, but need for more trials Table 3. Concerning the long-acting somatostatin analogue ocreotide the same conclusion can be drawn based on an ad hoc meta-analysis of eight randomised controlled trials (Dumonceau et al. Octreotide increases namely the tone of the sphincter of Oddi, and therefore this partial beneficial effect of the reduced enzyme secretion may be effective only with sphincterotomy together. Some data suggest that the effect of octreotide may be dose dependent and more than 0. Gabexate mesilate in six randomised controlled trials, while ulanistatin in four randomised controlled trials have been evaluated. Furthermore, the prophylactic effect of gabexate with ulanistatin was compared in two clinical trials. The same conclusion can be drawn from a recently published meta-analysis (Seta & Noguchi 2011) on the basis of which it can be stated that the primary studies were not of high quality enough to come to the proper consequences.
Fungus ball would appear as mobile buy leukeran from india, often multiple purchase leukeran 5mg mastercard, laminated generic leukeran 2mg with visa, gas-containing filling defects within the bladder. Rationale: Findings: Exophytic left renal mass containing a small amount of gross fat (density 52. Renal cell cancer can rarely contain fat, but generally as a large very heterogeneous mass. Although 80% do contain fat, it is intracytoplasmic and thus detectably as low density (< 10 H. Perirenal liposarcoma may contain fat, but would typically be larger and more complex in appearance. No abnormal echotexture or abnormal hyperemia of visualized portion of either testicle on color Doppler. In testicular torsion, there could be hyperemia around a torsed testicle as a late finding, but there would be reduced or absent flow to the testicle. As above, in this case there is normal flow to the testes bilaterally, precluding the diagnosis of testicular torsion. Enlargement and hyperemia of the left epididymis, as seen here is characteristic of left epididymitis. Although there is evidence of left epididymitis, as above, the left testicle has normal flow on color Doppler, and normal echogenicity, with no evidence of orchitis. This is not a typical appearance for schistosomiasis; in particular, no calcifications of the masses are seen. Rationale: Findings: Heterogeneous echotexture of the testicle, with no flow within the testicle on power Doppler. The absence of flow on power Doppler is consistent with testicular torsion, but the presence of heterogeneity within the testicle is consistent with infarct, indicating the testicle is no longer viable. The absence of flow confirms torsion, with the heterogeneous appearance indicating infarction. With acute epididymo-orchitis, there would be abnormal increased flow within the testicle in the region of orchitis, not absent flow as in this case. Seminoma if this large would be hypervascular, not have absent flow as in this case. Mixed germ cell tumors with teratomatous components will often have cystic areas within them, but do not form a network of tubule like this. Also germ cell tumors would not be expected to be centered in the mediastinum testes bilaterally. Testicular abscess usually occurs as a complication of epididymo-orchitis, for which there is no evidence in the images. This is a typical appearance of tubular ectasia of the rete testis, with variable size cystic lesions near the mediastinum testes bilaterally. Tunica albuginea cysts occur within the tunica surrounding the testis, and are usually solitary and small, 2-3 mm.

You are shown duplex Doppler ultrasound images of the right greater saphenous vein during a Valsalva maneuver. Rationale: On Valsalva maneuver there is retrograde flow in the great saphenous vein indicating venous valvular insufficiency with reflux. Rationale: the frontal aortogram shows no functioning left kidney, no filling of the splenic artery and collateral flow from the left colic branch of the inferior mesenteric artery into the mid colic artery. The lateral shows the superior mesenteric artery to be occluded at its origin and an all but occluded celiac trunk. Uterine fibroid vascularization and clinical relevance to uterine fibroid embolization. Rationale: Although there are variants, the gonadal arteries most commonly are paired structures arising from the aorta just inferior to the renal arteries. Cholelithiasis Key: C References: Valji K, Vascular and Interventional Radiology, Saunders 2006. Rationale: the image shows a biliary drainage catheter passing from the right hepatic duct through the common hepatic duct. Unlike pancreatic carcinoma that typically obstructs the common bile duct, the usual point of biliary obstruction with cholangiocarcinoma is at the confluence of the right and left hepatic ducts as demonstrated here. The antidote for an overdose of midazolam (or any other benzodiazepine) is flumazenil.
