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: hyponatremia major surgical or invasive procedure: none history of present illness: 66 yo male with stage 4 small cell lung cancer metastatic to brain, bipolar disorder no longer on depakote, presents to clinic today to receive c1d8 of cisplatin/ironotecan. the patient was found to have a sodium of 120, and after ivfs with the thought the patient was slightly hypovolemic given his low bp, the na was 116. the patient was very anxious and agitated today as well. he states he's been very fatigued recently, but that "of course i'm tired considering all i've been through". he denies nausea or vomiting, but does report mild diarrhea from the chemo. he denies headaches, sob, cp, weakness, or numbness. he is very anxious and agitated during interview. past medical history: onc history: recently diagnosed for small cell lung cancer metastatic to brain. now has completed first cylce of cisplatin and ironotecan. pmh: hypertension hyperlipidemia anxiety treated with depakote x10 years copd but not on inhaled medication reports nl psa and colonoscopy with 2 benign polyps social history: worked as a customer service supervisor until laid off . lives with wife. quit smoking 2 weeks ago, 1.5 ppd x 50 years prior to that, drank 1 beer/day until late . family history: half-brother with copd physical exam: vs: t: 98.5 hr: 58 bp: 128/72 rr: 18 sat: 99% on ra gen: well appearing man, agitated, anxious heent: sclera anicteric, oropharynx clear, mmm neck: no cervical lymphadenopathy cv: normal s1/s2, rrr, no m/r/g, 2+ dp/pt pulses bilaterally resp: decreased bs bilaterally, no wheezes or rhonci abdomen: soft, nontender, nondistended, normoactive bowel sounds ext: no peripheral edema, no clubbing, cyanosis neuro: a + o x 3, agitated and anxious, repeating himself cn ii-xii intact though difficulty following commands to evaluate eoms- unable to bring left eye medially, no nystagmus, motor both upper and lower extremities, sensation intact to light touch, dtr + throughout pertinent results: labs: 07:26pm glucose-254* urea n-22* creat-0.9 sodium-118* potassium-4.3 chloride-83* total co2-23 anion gap-16 07:26pm osmolal-260* 03:45pm sodium-116* 11:30am urea n-23* creat-0.9 sodium-120* potassium-4.6 chloride-86* total co2-23 anion gap-16 : head ct impression: multiple small hypodense lesions with surrounding vasogenic edema, better seen on recent mri and likely represents metastatic disease. no evidence of intracranial hemorrhage. . brief hospital course: # hyponatremia: patient was initially admitted to the intensive care unit for closer monitoring. he received hypertonic saline, and was carefully monitored as his sodium was corrected nicely to his goal of 125-126, taking care not to correct no more than meq in the first 24 hours. his hypertonic saline was discontinued and he continued with fluid restriction and a high salt diet. he was monitored on telemetry and neurological checks were completed frequently. it was felt that he had siadh, given that his hyponatremia worsened initially with intravenous fluids, his low urine osmolality, and his euvolemic state. due to his known brain metastases and concern over worsening edema and risk of seizures, he was treated with keppra and steroids to minimize the edema and seizure risk. - the nephrology team was consulted and also assisted with management of the patient's hyponatremia. . # small cell lung cancer: patient had recently completed cycle 1 of cisplatin and irinotecan on day of admission. his allopurinol was continued. outpatient radiation oncology appointment was set up in , closer to the patient's home, for the week following his discharge. - he was continued on keppra and steroids, which were slowly tapered down, for his known brain metastases. - his chemotherapy was held due to continued diarrhea and neutropenia. - patient was neutropenic, but his cell counts trended upward prior to discharge and he was no longer neutropenic at that time. he had no fevers or signs of infection while neutropenic. . # diarrhea: the patient noted diarrhea that was worst during his first few days of hospitalization. studies for c. difficile were negative, and his diarrhea was managed with immodium as needed. it resolved prior to discharge. . # hypertension: patient initially was hypertensive, and his home medications of atenolol and lisinopril were continued. however, during his course his blood pressure was on the low side, so these medications were held. . # bipolar disorder/anxiety: depakote had been discontinued 1 week prior admission due to concern over possible interaction with chemotherapy. although hyponatremia was felt to have some role in the patient's agitation, it was also possible that the discontinuation of depakote was also playing a role. psychiatry was consulted and followed along during the patient's stay, and recommended seroquel and ativan to assist with his agitation. he was not felt to be manic during his stay. follow up appointments with psychiatry were coordinated and set up as well. . # hyperglycemia: patient was noted to have elevated blood sugars, which were felt to likely be secondary to steroids. his steroids were tapered down, but the hyperglycemia persisted. insulin and glucometer teaching were completed with the patient and his wife, and he was sent out on nph and a sliding scale of insulin. . # thrush: patient noted to have thrush, thought to be secondary to steroids. nystatin swish and swallow cleared his thrush nicely and was continued along with clotrimazole. . # fluids, electrolytes, nutrition: - heart-healthy diet was followed - 1l fluid restriction . # prophylaxis: - proton pump inhibitor was initiated due to steroid use. - subcutaneous heparin was used for dvt prophylaxis. - his home statin was continued for cardiac prevention. - physical therapy worked with patient and he was felt to be safe for discharge to home. . medications on admission: lipitor 80 mg once a day. lisinopril 10 mg daily allopurinol 300 mg daily levetiracetam 500 mg atenolol 50 mg daily compazine 10 mg q6h dexamethasone 4 mg q6h docusate sodium 100 mg zofran 8 mg q8h prn nausea ativan 0.5 mg q6h prn nausea diphenoxylate-atropine 2.5-0.025 mg q8h prn diarrhea. ambien 10 mg qhs discharge medications: 1. atorvastatin 80 mg tablet sig: one (1) tablet po daily (daily). 2. allopurinol 300 mg tablet sig: one (1) tablet po daily (daily). 3. levetiracetam 500 mg tablet sig: one (1) tablet po bid (2 times a day). 4. acetaminophen 325 mg tablet sig: 1-2 tablets po q6h (every 6 hours) as needed. 5. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 6. ondansetron 8 mg tablet, rapid dissolve sig: one (1) tablet, rapid dissolve po q8h (every 8 hours) as needed. 7. prochlorperazine 10 mg tablet sig: one (1) tablet po q6h (every 6 hours) as needed. 8. sodium chloride 1 g tablet sig: two (2) tablet po tid (3 times a day) as needed for hyponatremia. disp:*90 tablet(s)* refills:*0* 9. clotrimazole 10 mg troche sig: one (1) troche mucous membrane qid (4 times a day). disp:*120 troche(s)* refills:*2* 10. nystatin 100,000 unit/ml suspension sig: five (5) ml po qid (4 times a day): as needed for thrush. disp:*600 ml(s)* refills:*2* 11. loperamide 2 mg capsule sig: two (2) capsule po tid (3 times a day) as needed for diarrhea. disp:*30 capsule(s)* refills:*0* 12. dexamethasone 2 mg tablet sig: one (1) tablet po qpm (once a day (in the evening)). disp:*30 tablet(s)* refills:*2* 13. olanzapine 2.5 mg tablet sig: one (1) tablet po hs (at bedtime): take 2.5 mg at night for 3 more nights, then 5 mg per night for 7 nights, and then 10 mg per night after that, if tolerated. disp:*50 tablet(s)* refills:*2* 14. dexamethasone 4 mg tablet sig: one (1) tablet po qam (once a day (in the morning)). disp:*30 tablet(s)* refills:*2* 15. lorazepam 0.5 mg tablet sig: one (1) tablet po bid (2 times a day) as needed. 16. insulin nph human recomb 100 unit/ml suspension sig: one (1) vial subcutaneous as directed.: see attached sliding scale instructions for insulin administration. disp:*1 vial* refills:*2* 17. insulin supplies lancets for blood sugar testing. please administer 100. refills: 1. 18. one touch ultrasoft lancets misc sig: one y (120) lancets miscellaneous use as directed.: use to check blood sugars. disp:*120 lancets* refills:*2* 19. one touch ii test strip sig: one y (120) strips in as directed.: use with one touch ii glucometer for testing blood sugars as directed. disp:*120 strips* refills:*2* 20. alcohol prep swabs pads, medicated sig: one (1) package topical as directed.: use to clean skin prior to administering insulin. disp:*1 package* refills:*2* 21. humalog pen 100 unit/ml insulin pen sig: as directed subcutaneous tid with meals: see attached sliding scale. disp:*qs 1 month supply* refills:*2* discharge disposition: home with service facility: vna discharge diagnosis: primary diagnosis: hyponatremia . secondary diagnsos: metastatic small cell lung cancer discharge condition: stable, ambulating safely after being evaluated by physical therapy, with resolving cough. discharge instructions: you were admitted for a low blood serum sodium level. you were treated with fluid restriction and salt tablets. your sodium increased appropriately. . please take all medications as prescribed. please limit your fluid intake to 1 liter daily. . please call your primary care doctor, your oncologist, or go to the emergency room if you experience chest pain, shortness of breath, fever, chills, numbness/tingling/weakness in any of your arms or legs, increasing fatigue, sleepiness, or any symptoms that concern you or your family. followup instructions: oncology appointments: 1) , rn phone: date/time: 10am 2) , md at 9:30 am on . . you have an appointment with , rn on at 3:00 p.m. counseling center . , . please follow up with them to further evaluate your medications for your bipolar disorder. . you have an appointment with radiation oncology on tuesday, at 3:00 with dr. . the number for the office is (. please bring a copy of your imaging results--either a film or a cd, so that planning for radiation treatment may be made. the address is: hospital radiation therapy center -
