Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: spitting up blood major surgical or invasive procedure: none history of present illness: 84 y/o female with recent diagnosis in of diffuse large b cell lymphoma of the distal esophagus and proximal stomach, s/p one cycle of chop on and a second cycle of chop-rituxan on , on neulasta, who presents with hematemesis. she reports sudden onset of spiting up 2-3 tablespoons of bright red blood after severazl bites of and cantolope. she describes a substernal burning feeling after eating, followed by spitting up blood. this happpened again when she reached the ed, spitting up 3-4 tablespoons more of bright red blood. she reports decreased po intake over the last several months due to poor appetite, with weight loss, early satiety, and occassional substernal and epigastric burning after eating. she denies fever, chills, chest pain, dyspnea, vomiting, abdominal pain, or dysuria. she did recently have some constipation, for which she took senna and colace and then had loose stools. she denies black or bloody stools. she reports rare alcohol use and has no history of liver disease. . in the ed, t 98.9 hr 88 bp 150/84 rr 18 sat 100%ra. ng lavage for one liter cleared to pink with specks of blood. treated with 40 mg iv protonix and 4 mg iv zofran. guaiac negative. past medical history: 1. diffuse large b cell lymphoma of the ge junction- diagnosed by biopsy during an egd on . pathology showed diffuse large b-cell lymphoma staining positive for lca, cd20, bcl6, and mun1. subsequent pet-ct showed disease localized to the distal esophagus/proximal stomach. she received cycle one chop on . the adriamycin dose was initially reduced and rituxan held. she tolerated the first cycle of chemotherapy well. she began cycle 2 chop-rituxan at full dose on . she is scheduled to have a repeat pet-ct on . they plan to repeat her bone marrow biopsy when her counts recover. 2. peptic ulcer disease s/p partial gastrectomy & tumor excision 3. mild diastolic dysfuction by echo 4. s/p appendectomy. 5. nephrolithiasis social history: she lives at home with her daughter in , . she is retired, but previously worked in retail. widowed. three daughters and a son. than two alcohol drinks per week. tobacco: smoked for 30 years, quit 40 years ago. alcohol: rare use on social occasions, drinking two glasses per night. no drug use. is catholic. family history: her father died of a neck cancer at 64 years. her mother died of a malignancy that involved her eye at 38 years. one sister has disease. her other sister and brother have cardiovascular disease. physical exam: vital signs: t 99 hr 85 bp 134/82 rr 14 sat 100%ra gen: pleasant, cachectic, elderly female in no distress, occassionaly spitting up pink tinged mucous heent: sunken eyes, moist mucous membranes. neck: no lad, no bruits heart: regular with 2/6 systolic flow murmur. chest: lungs clear. abdomen: good bowel sounds, soft, nt, nd, no palpable masses. extremities: no edema, good pulses. skin: warm, dry neuro: a&ox3, cranial nerves ii-xii intact, strength 5/5 throughout pertinent results: 06:15pm wbc-9.0# rbc-3.97* hgb-12.4 hct-35.3* mcv-89 mch-31.4 mchc-35.2* rdw-13.5 plt count-179 06:15pm neuts-73* bands-8* lymphs-3* monos-9 eos-0 basos-0 atyps-3* metas-2* myelos-2* . 11:05pm hct-31.8* . 06:15pm pt-13.3 ptt-22.1 inr(pt)-1.1 . 06:15pm glucose-119* urea n-16 creat-0.7 sodium-143 potassium-3.6 chloride-102 total co2-29 anion gap-16 06:15pm alt(sgpt)-15 ast(sgot)-19 alk phos-92 amylase-65 tot bili-0.4 06:15pm lipase-15 . 06:15pm iron-66 06:15pm caltibc-303 vit b12-1304* folate-16.0 ferritin-811* trf-233 . brief hospital course: assessment: 84 y/o female with diffuse large b cell lymphoma at the ge junction and new hematemesis, s/p egd on which confirs mass at ge junction with 2 cm bleeding ulcer. ddx included erosion of lymphoma, - tear, and hsv esophagitis . 1. hematemesis: likely due to bleeding from erosion of lymphoma at ge junction vs hsv esophagitis. hct stable during hospital stay. because of possibility of hsv esophagitis, she was switched from prophylactic dose to treatment dose acyclovir. pt is to continue ppi daily, and stay on a liquid diet x 2 weeks pending repeat egd (in 2 weeks). at that time biopsy results will need to be followed up, and well as h. pylori results. . 2. lymphoma: unclear if this is progression of disease. last treament in late . bmt will see pt in clinic for further management of diffuse large b cell lymphoma. of note, she is on levofloxacin for ppx after chemo, but her anc is no longer depressed. whether or not to continue levofloxacin can be evaluated in clinic. . 3. bandemia with rising wbc count: likely due to recent chemo with neulasta treatment. afebrile with no symptoms or signs of infection. can be followed in clinic. . 4. anemia: likely 2/2 blood loss from hematemesis. however, hct stable for the length of stay. . 5. diet: pt is to continue a liquid diet for 2 weeks until f/u egd . 6. code: full, but does not wnat to be on long term life support. . 7. contact: , and daughter . medications on admission: acyclovir 400 mg t.i.d. prophylaxis levofloxacin 500 mg daily prophylaxis since getting chemo aciphex 20 mg daily taking on and off. valium 5 mg daily. xalatan eyedrops. meclizine p.r.n. senna one to two tablets b.i.d. colace 100 mg b.i.d. . discharge medications: 1. diazepam 5 mg tablet sig: one (1) tablet po daily prn (). 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 3. latanoprost 0.005 % drops sig: one (1) drop ophthalmic hs (at bedtime). 4. meclizine 12.5 mg tablet sig: one (1) tablet po q8h (every 8 hours) as needed for vertigo. 5. senna 8.6 mg tablet sig: 1-2 tablets po bid (2 times a day) as needed. 6. levofloxacin 500 mg tablet sig: one (1) tablet po q24h (every 24 hours). 7. acyclovir 800 mg tablet sig: one (1) tablet po 5x/d (). disp:*150 tablet(s)* refills:*2* 8. protonix 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po once a day. disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* discharge disposition: home discharge diagnosis: primary: upper gi bleed from ulcer near lymphoma at ge junction secondary: 1. diffuse large b cell lymphoma of the ge junction- 2. peptic ulcer disease s/p partial gastrectomy & tumor excision 3. mild diastolic dysfuction by echo 4. s/p appendectomy. 5. nephrolithiasis discharge condition: vss stable, afebrile, hct stable discharge instructions: you were admitted to the hospital due to vommitting of blood. a test called an egd was performed to evaluate the cause of the bleeding. during the egd a small ulcer was found, and biopsies were taken. the results of this biopsy are not available right now, but you will be able to discuss the results with your health care provider in the clinic. by the recommendation of the gi team that saw you, you are to limit your diet to liquids for 2 weeks until another egd is performed. you are to start taking a new medication called protonix, and stop taking aciphex. you are also to start taking acyclovir at a higher dose. . if you have any more symptoms of spitting up blood, chest pain, nausea, or vommiting you are to go to the hospital immediately. . please go to all of you follow up appointments as scheduled. . please take allo of your medications as perscribed. followup instructions: for egd: the office will call you with appointment time, it should be in 2 weeks. if they do not call you by please call them at provider , md phone: date/time: 10:00 am provider , md phone: date/time: 10:00 provider , md phone: date/time: 10:00 provider , rn phone: date/time: 11:00 md procedure: esophagogastroduodenoscopy [egd] with closed biopsy dilation of esophagus diagnoses: intestinal bypass or anastomosis status iron deficiency anemia secondary to blood loss (chronic) cachexia personal history of urinary calculi stricture and stenosis of esophagus ulcer of esophagus with bleeding personal history of peptic ulcer disease herpes simplex with other specified complications other malignant lymphomas, intra-abdominal lymph nodes
