The most common cause of upper GI bleeding is PUD discount 100mg kamagra soft visa, accounting for 60% of cases found on emergency endoscopy buy 100mg kamagra soft. About 50% of cases will have a clean- based ulcer with a low probability of rebleeding, so that pharmacologic intervention is required. Adherent clots, visible vessels, or active bleeding portend less favorable outcomes unless endoscopic or surgical treatment is applied. Use of NSAIDs and Helicobacter pylori infection are the two most important risk factors; heavy alcohol ingestion and smoking are also associated with PUD bleeding risk. A 39-year-old woman with a history of cirrhosis presents to the emergency department with massive hematemesis. Volume resuscitation with intravenous normal saline is initiated, and emergent EGD is planned for further evaluation and management. Which of the following endoscopic interventions is considered first-line therapy in the management of esophageal varices? Injection therapy Key Concept/Objective: To understand that band ligation is first-line therapy for the manage- ment of esophageal varices With variceal bleeding, endoscopic treatment is used primarily for esophageal varices; the techniques include sclerotherapy and band ligation. Sclerotherapy utilizes a variety of scle- rosants to induce variceal thrombosis, with sodium tetradecyl sulfate and ethanolamine oleate used most frequently. Complications include retrosternal chest pain, low-grade fever, ulceration (usually deep ulcers that heal within 3 weeks), dysphagia, delayed perfo- ration (1 to 4 weeks later), and stricture formation. The popularity of sclerotherapy has diminished as a result of these complications. Intravariceal injections are more effective than paraesophageal injections in controlling bleeding. Band ligation is now considered the first-line endoscopic therapy for esophageal varices. The band ligator is readily attached to the distal end of the endoscope, which is advanced to the varix; the endoscopist then suctions the varix into the ligator cap and deploys a rubber band around the varix. This results in the plication of the varices and sur- rounding submucosal tissue, with fibrosis and eventual obliteration of varices. Comparative studies report better initial control of bleeding (91% versus 77%) and rebleed- ing rates (24% versus 47%) with band ligation than with sclerotherapy. Complications of banding include retrosternal chest pain, dysphagia from compromise of the esophageal lumen, band ulceration (usually superficial ulcers that heal within 2 weeks), overtube 4 GASTROENTEROLOGY 17 injury, and perforation. A 36-year-old man presents to your clinic complaining of fatigue. Review of systems is positive for occasional diarrhea, which the patient has been experiencing for several months, and for a 20-lb weight loss. Laboratory tests reveal iron deficiency anemia, and the patient tests positive on a qualitative fecal fat test. Results of an upper endoscopy and a colonoscopy are normal. Which of the following tests would be most likely to provide helpful information in the workup of this patient? Selenium-75–labeled homocholic acid-taurine (75SeHCAT) absorption test B. Tissue transglutaminase antibody Key Concept/Objective: To understand that gluten-sensitive enteropathy (GSE) is a cause of iron deficiency anemia Patients with GSE may present with a variety of complaints, including weight loss, fatigue, abdominal cramps, distention, bloating, and diarrhea. Other presentations include iron deficiency anemia, osteoporosis, and easy bruising. In a patient in whom the suspicion of GSE is high, a positive tissue transglutaminase antibody test makes the diagnosis almost certain. Alternatively, the diagnosis might rest on small bowel biopsy findings. Another helpful test is the identification of an endomysial antibody. The presence of fecal fat is helpful in this patient because it confirms the suspicion of an underlying malabsorptive disorder. The xylose absorption test evaluates the absorptive surface area of the small bowel. The bentiromide test is a noninvasive test to evaluate for pancreatic exocrine insuf- ficiency.

In order to try to mainly train the knee joint stabilizers I suggest that these exercises should be performed in a standing position with a slightly flexed knee joint. Balance training on a balance board can initially be performed standing on one leg with addition of electrical stimulation of VMO to facilitate a proper balance between VMO and VL (Figure 9. When good muscle con- trol is achieved the patient can continue the balance exercise standing on one leg without electrical muscle stimulation (Figure 9.

The family is pres- ent and disagrees with his decision kamagra soft 100 mg with amex, saying that he is not competent to make such a decision because of his medical condition discount 100mg kamagra soft fast delivery. The family demands that you proceed with all the measures needed to save his life. Which of the following would be the most appropriate intervention for this patient? Proceed with intubation and obtain an ethics consult ❏ B. Follow the patient’s wishes and continue with comfort measures only ❏ C. Proceed with life support interventions and follow the family’s wishes Key Concept/Objective: To know the criteria for decision-making capacity Decision-making capacity refers to the capacity to provide informed consent to treatment. This is different from competence, which is a legal term; competence is determined by a court. Any physician who has adequate training can determine capacity. A patient must meet three key criteria to demonstrate decision-making capacity: (1) the ability to under- stand information about diagnosis and treatment; (2) the ability to evaluate, deliberate, weigh alternatives, and compare risks and benefits; and (3) the ability to communicate a choice, either verbally, in writing, or with a nod or gesture. In eliciting patient preferences, the clinician should explore the patient’s values. This patient met these three criteria when he made his decision about advance directives, and his wishes should be respected. There CLINICAL ESSENTIALS 15 is no need for an ethics consult under these circumstances. A patient with terminal lung cancer on home hospice is brought to the hospital by his family for admis- sion. He is agitated and confused, and his family is unable to care for him at home. Upon examination, the patient is disoriented and appears to be having visual hallucinations. Which of the following statements is true regarding delirium in terminal patients? Benzodiazepines are first-line therapy for treatment of delirium ❏ B. Physical restraints should generally be used for patient safety in the set- ting of delirium ❏ D. The subcutaneous route is a viable option for the administration of benzodiazepines ❏ E. Delirium generally occurs only in patients with underlying dementia Key Concept/Objective: To understand the treatment of delirium in the terminally ill patient Pharmacologic treatment for relief of symptoms of delirium is best achieved through the use of antipsychotic agents such as haloperidol or risperidone. Benzodiazepines and seda- tives should be used only if antipsychotic agents fail. In as many as 25% of terminally ill patients who experience delirium characterized by escalating restlessness, agitation, or hal- lucinations, relief is achieved only with sedation. Even in a terminally ill patient, treat- ment of the underlying cause (e. Physical restraints can actually be a precipitating factor for delirium and should be avoided in the delirious patient whenever possible. In patients who cannot take oral medications and in whom a functional intravenous line is not available, the subcuta- neous route is a rapidly effective way to administer certain medications, including mida- zolam. Patients with underlying dementia are predisposed to delirium, but delirium can occur in patients with other comorbidities.
