The first time it happened pantoprazole 40 mg online chronic gastritis gerd, she also felt a little nauseated generic pantoprazole 20 mg otc gastritis diet ����, but she did not vomit order pantoprazole 40 mg mastercard eosinophilic gastritis definition. In her job, she has to look down to fold clothes coming off the line, and the dizziness occurs if she looks down too quickly. Best treatment: A maneuver to dislodge the loose otolith from the affected semicircular canal can be performed in t he office, or medicat ions such as mecli- zine can be prescribed to treat the symptoms. For severe symptoms, diazepam (Valium) or transdermal scopolamine patches can be prescribed. Distinguish “benign” positional vertigo from more serious central causes of ver t igo. Co n s i d e r a t i o n s This previously healthy 42-year-old woman complains of acute onset of“dizziness,” especially when moving her head quickly. Upon further questioning, the symptom of vertigo is est ablished, that is, the perception of movement when she is stat ion- ary. She has no neurologic symptoms such as cranial nerve dysfunct ion, headache, or history of head trauma. The patient most likely has benign posit ional vertigo, which is the most common cause of acute vertigo. The pathophysiology likely is debris in the semicircular canals of t he middle ear. Ant icholinergic medicat ions and posit ional maneuvers are often useful in therapy. Peripheral vertigo is caused by the labyrinthine apparatus or vest ibular nerve, whereas central vertigo is cau sed by a br ain st em or cer ebellar pr ocess ( Table 39– 1). The first step in evaluating patients with this complaint is to ask open-ended questions about the sensation (“What do you mean by dizzy? The majority of patients who complain of dizziness are suffering from a distinctive symptom—presyncope, dysequilibrium, or vertigo— which can be elucidated by history or physical examination. Pat ient s may describe feeling ligh t -h eaded, a graying of vision, or “n early blacking out. The causes of this sympt om are t he same as t hose for syncope: most often vasovagal attacks, ortho- st at ic hypot ension, or cardiac arrhyt h mias. The evaluat ion of t hese pat ient s is t he same as for those with syncope (see Case 9). It is a multifactorial disorder, commonly seen in elderly patients with impaired vision, peripheral neu- ropathy and decreased proprioception, and musculoskeletal problems causing gait instability. It may also be one of the presenting symptoms of patients with primary movement disorders such as parkinsonism. T hese symptoms may be exacerbated by medications, particularly in the elderly; examples include antihypertensives, anti- depressants, and anticholinergic agents that can cause orthostatic hypotension or dizziness as a side effect. Ve rt i go is the illusory sensation of movement or spinning, and usually arises from a d isor d er in the vest ibu lar syst em. In the inner ear, the semicircular canals t rans- duce rotational acceleration, while the otolith organs (utricle and saccule) sense linear accelerat ion. The vest ibular o cular reflex maintains visual stability during head movements through these same cranial nerves, as well as projections through the medial longitudinal fascicu lus. This int egrat ion of the in n er ear, brain, an d eyes explain s wh y nystag- mus is observed in patients during bouts of vertigo. It is asymmetry or discordance between the vestibular inputs from the two labyrinths or their central pathways that causes the sensation of vertigo. Physiologic vertigo includes motion sickness, or the sensation of movement that may occur when watching motion pictures. The first task in evaluating a patient with vertigo is to try to distinguish peripheral (labyrin- thine apparatus or vestibular nerve) from central (brainstem or cerebellum) causes of ver t igo. Central causes, such as cerebellar hemorrhage or infarction, can be immediately life threatening or signify serious underlying disease and require urgent investigation. Peripheral causes typically signify less serious diseases and can be managed comfort- ably on an outpatient basis. T hus, the presence of other neurologic abnormalities, headache, or evidence of increased intracranial pressure is critical to address. Typically, this t ype of vertigo is precipit ated by changes in head position, as in rolling over in bed, bending over, or looking upward. Patients may not have all of the typical symptoms at the same t ime; however, t he first bout usually is abrupt in onset and associated wit h nausea. Theclinicianholdsthepatient’sheadandmovesthepatient rapidly from a sitting to a head-hanging position, first with the head facing one side and then facing the other side. Individuals with benign positional vertigo will demonstrate nystagmus after a delay of a few seconds. Patients turn their head toward the examiner and lay down quickly wit h t heir head hanging somewhat lower t han t he body. T h er e is a la g o f 5 t o 1 0 seco n d s fo r the n yst agm u s t o occur, and it is accompanied by the sensation of vertigo. Ant ich olin er gic agen t s, su ch as meclizin e or d iph en h yd r am in e, or ben zo- diazepines may help lessen symptoms. Alternatively one may attempt positional maneuvers in the office to displace the otolith from the semicircular canal back into the utricle or saccule, such as the Epley maneuver (Figure 39– 2). Table 39– 2 lists other causes of vert igo and their associated clinical features. Other causes of peripheral vertigo include Ménière disease and acoustic neu- roma. Patients may experience episodes of vertigo lasting for minutes to hours, usually associ- ated wit h unilateral t innitus, hearing loss, and ear fullness. Treat ment includes ant ihist amines or ant icholinergics during acute att acks, and diuret ics to reduce endolymphat ic fluid. Because they are slow-growing, the subtle imbalances in vestibular input are often compen- sated, and pat ient s may not experience significant vert igo, only vague imbalance. Finally, approximately 10% to 15% of pat ient s have nonspecific dizziness, wh ich can n ot be classified as ver t igo, pr esyn cop e, or dysequ ilibr iu m. Pat ient s can n ot clear ly d escr ibe on e of t h ese syn d r om es, can r ep or t on ly that they feel “dizzy,” h ave vagu e o r u n u su al sen sat io n s, an d h ave n o r m al n eu r o lo gic an d vest ib u lar exam in a - tions. The majority of these patients have some underlying psychiatric disorder, such as major depression, generalized anxiet y, or panic disorder. O ft en t he diz- ziness is associated with hyperventilation and can be reproduced in the office by purposeful hyperventilation. Treatment should be aimed at reassurance regarding the lack of pathologic causes of dizziness and at therapy for the underlying disorder wit h medicat ion such as serotonin-specific reupt ake inhibitors or benzodiazepines for an xiet y disorders. Then the patient’s head is systematically rotated so that the loose particles slide out of the posterior semicircular canal into the utricle. W hen asked to describe the feeling, she gives a vague story of just feeling like “her head is too big” and she “feels like is not really here. H is medical history is notable for coronary artery disease and well-controlled hypertension.

Diagnostic paracentesis can be used to assess for infection as well as to seek an etiology of the ascites buy pantoprazole 20 mg lowest price gastritis inflammation diet. The most common causes of chronic hepatitis are viral infections order pantoprazole with american express gastritis diet ����, su ch as hepatitis B and C buy 40mg pantoprazole overnight delivery gastritis diet for gastritis, alcohol use, chronic exposure to other drugs or toxins, and autoimmune hepatitis. Less common cau ses are in h er it ed met abolic disorder s, su ch as h emo- ch r omat osis, W ilson d isease, or α -antitrypsin deficiency. Hepatitis C infection is most commonly acquired through percutaneous exposure to blood. Risk fact ors for acquisit ion of h epat it is C in clude int r aven ou s dr ug u se, sharing of st raws to snort cocaine, hemodialysis, blood t ransfusion, t attooing, and piercing. The clinician must have a high index of suspicion and offer screening to those individuals with risk factors for infection. Approximately 70% to 80% of all patients infected with hepatitis C will develop chronic hepatitis in the 10 years following infection. Among those with cirrh osis, 1% t o 4% an nually may develop h epat ocellular carcinoma. Previously, t he treat- ment of choice for chronic hepatitis C was combination therapy with pegylated alpha- interferon and ribavirin. Interferon-based therapy has many side effects, such as influenza-like symptoms and depression, and hemolysis with ribavirin. N ew agent s, such as ledipasvir/ sofos- buvir and daclatasvir, have the advantages of being all oral, interferon-free regi- mens with very favorable side effect profile, and very high rates of cure (sustained virologic response), but the regimens are very costly, which may limit their use. Treatment is rapidly evolving, and guidelines for hepatitis C are frequently updated (www.

Alcoh olic cirrhosis is one of the most common forms of cirrhosis encountered in the United States. It is related to chronic alcohol use, but there appears to be some hereditary predisposition to the development of fibrosis, and the process is enhanced by con- comit ant in fect ion wit h h epat it is C. C lin ical sympt oms are pr oduced by the h epat ic dysfunction, as well as by portal hypertension (Table 24– 2). Loss of funct ioning h epat ic mass leads t o jaundice as well as impaired synt h e- sis of albumin (leading to edema) and clott ing factors (leading to coagulopat hy). Fibrosis and increased sinusoidal resist ance lead to port al hypertension and it s complicat ion s. Esophageal and gastric varices are p r on e t o bleed in g, wh ich m ay p r o- duce massive hemorrhage, or more subtle bleeding that can trigger encephalopathy. Treatment may include infusion of octreotide to cause splanchnic vasoconstriction and reduce port al pressure. Esophageal varices can also be t reated endoscopically with ligation or banding to treat or prevent bleeding, or with sclerotherapy for act ive bleeding. It may be pre- cipit at ed by numerou s fact ors in clu din g elect rolyt e dist ur ban ce, in creased diet ar y protein load (including digestion of blood), or infection. Treatment is aimed at cor- recting underlying causes, as well as administration of lactulose, a nonabsorbable disaccharide that causes colonic acidification and elimination of nitrogenous waste. Poorly absorbed antibiotics such as neomycin may also be administered orally as adjunct ive t reat ment. The most common cause of ascites is portal hypertension as a consequence of cir- rho si s. Ascit es may be a r esu lt of exu dat ive causes such as in fect ion (eg, t ubercu lous peritonitis) or malignancy. It is important to try to determine the cause of ascites in order t o look for reversible causes and for serious causes, such as malignancy, and to guide t herapy. Ascit ic fluid is obt ained by paracentesis and examined for protein, albumin, cell count with differential, and culture. Loop diuret ics are oft en combin ed wit h spiron olact on e t o pr ovide effect ive diuresis and t o maint ain normal pot assium levels. Spontaneous bacterial peritonitis is a relatively common complication of ascites, thought to be caused by translocation of gut flora into the peritoneal fluid. Symptoms include fever and abdominal pain, but oft en t h ere is paucit y of signs and sympt oms. H owever, flu id cu lt u r es, wh en p osit ive, u su ally r eveal a sin gle or gan ism, most oft en gr am-n eg- at ive enteric flora but occasionally enterococci or pneumococci. T his is in cont rast to secondary peritonitis, for example, as a consequence of intestinal perforation, wh ich usually is polymicrobial. Empiric t h erapy includes coverage for gram- positive cocci and gram-negative rods, such as intravenous ampicillin/ sulbactam, or a third-generation cephalosporin such as cefotaxime. Other complications of advanced cirrhosis include hepatorenal syndrome, wh ich typically presents as progressive decline in renal function in patients with signifi- cant ascit es. T h e pat h ogen esis is p oor ly u n d er st ood, but app ear s t o involve mu lt i- factorial renal vasoconstriction. Treat ment is difficult, and prognosis is often poor, unless patients proceed for liver transplant. Patients being considered for transplant are stratified according to scoring sys- tems to estimate disease severity and survival. An older scoring system, the Child-Pugh system, also classifies severit y of disease, wit h class A having t he best prognosis and class C the worst. Choose the one cause (A-G) that is probably responsible for the patient’s presentation. Select the cau se (A-G ) that is pr obably r esp on sible for the pat ient ’s pr esent at ion. Select the cause that is probably respon- sible for t he pat ient’s present at ion. Pick t he cause from t he following that is probably responsible for the patient’s presentation. Idiopathic or autoimmune hepatitis is a less-well-understood cause of hepatitis that seems to be caused by autoimmune cell-mediated damage to hepatocytes. D iabet es mellitus, cirrhosis of t he liver, h ypogonadot ropic h ypogonadism, art h ropat hy, and cardiomyopat hy are among the more common end-st age development s.

Sclerosing cholangitis is an autoimmune destruction of both the intrahe- patic and extrahepatic bile ducts and often is associated with inflammatory bowel disease, most commonly ulcerative colitis. Patients present with jaun- dice or symptoms of biliary obstruction; cholangiography reveals the charac- teristic beading of the bile ducts. Primary biliary cirrhosis is thought to be an autoimmune disease leading to destruction of small- to medium-size bile ducts.
