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: lorazepam attending: chief complaint: found unresponsive major surgical or invasive procedure: chest tube placement, s/p endotracheal tube on ventilator history of present illness: 18 yo m with no pmh found outside with agonal breathing, pupils pinpoint, serum tox neg, no chg in ms with 5 mg narcan, intubated, no documented o2 sat, t28.2c, hr 40's, bp stable, put on bear hugger and bilateral chest tubes were placed for rewarming given severe hypothermia, head ct neg, wbc neg, started on acyclovir, clinda, decadron, ceftriaxone, vanco. given 5-6 l of ns with one liter of na bicarb. cxr with bl upper lobe alveolar opacification. abg 6.46/57/278, lactate 7.8. on ros, spoke to family - feeling ill x2-3 days, vomiting, burning in stomach 2 days ago, diaphoretic at times, thinks may be using heroine, cold/cough, acting "stupid" x 2wks. last seen at 1pm, found at 3am outside. 3 ambien found in pocket. when pt was subsequently more alert he states he used klonopin which he got for free from someone he knows. he recalls getting the klonopin and being near the water, then has no recollection of travelling from there to , where he was found. pt also reports he was wearing new sneakers and had cash and a check in his pocket, neither of which he had when he was found. he took 20 pills in order to get high, not to hurt himself, and reports having done this once before at age 15, after which he "blacked out" for >12 hours and was monitored by his mother, but not brought to the hospital at that time. the two friends with whom he was using at that time were both admitted to the hospital. the pt denies any other ingestions, although he states he is unsure if he had alcohol the evening of admission. states that in the last three years all he has used is marijuana and alcohol, drinking up to a 6 pack of beer in one sitting. specifically denies cocaine, crack, crystal methamphetamine, heroin. past medical history: passed physical exam to get into airforce. no surgeries. social history: smokes ppd x several years, drinks etoh heavily up to 6 beers at a time, but patient does not believe he is a heavy drinker, +h/o heroin use per brother, recent hs graduate, airforce delayed entry program. pt reports having a group of friends who all drink, smoke cigarettes and use marijuana together. if he thinks about it, he can come up with only one friend who does not smoke, and that friend went away to college this year. family history: no h/o sz, maternal aunt . no htn, no dm physical exam: t33.8 (92.8), 130/71 initially off pressors, now on levo 105/62, hr 108 (initially 40's), sa o2 95-100% on vent. ac 450x28, peep 20, fio2 100%, pip 41. abg: 7.35/35/52 cvp 29 unresp to painful stimulus perl, 2-3 mm cv: tachy, reg, no m pulm: bl

initial abg: po2-278* pco2-57* ph-6.46* total co2-5* base xs--42 cxr: initial chest xray and repeat xrs throughout time in unit showed bilateral patchy infiltrate consistent with ards and possible aspiration. on arrival to floor, pa and lateral cxr showed rll retrocardiac infiltrate likely consistent with aspiration pneumonia. brief hospital course: is an 18 year old man with history of substance abuse who presented to ed hypothermic, nonresponsive, and with pinpoint pupils after being found down on the street in the neighborhood. was admitted to hte micu. urine tox was puzzingly initially negative but repeat after one hour was positive for opiates and benzos. notably, the patient was already on sedation at this time. this may represent lab error with the first sample, especially since the patient later admitted to ingesting benzos. after several days in the hospital, when his mental status improved, the patient admitted to taking 20 klonopins and possibly an unknown amount of alcohol, but denied any other ingestions. the patient initially presented quite hypothermic and required bilateral chest tubes in the icu for re-warming. it was felt that hypothermia was secondary to environmental exposure as patient was found down outside. as the patient's temperature improved, his acute renal failure (cr 2.9), bp, and oxygenation also improved. notably, the patient developed massive subcutaneous emphysema in abdomen and pneumomediastinum as a result of chest tube placement, which resolved on its own. on arrival, the patient was extremely acidemic (ph 6.46) and hypoxic and was intubated. he remained intubated for 5 days and self-d/ced his endotracheal tube. he was also hypotensive requiring levophed for 2 days. the patient's ards, hypoxia, and leukocytosis were believed to be secondary to aspiration pneumonia, for which he was started empirically on ceftriaxone and clinda iv. infectious work up also included lp for rule out meningitis given the patient's altered mental status and inability to provide history on admission. the lp was negative for overt infection and csf culture was negative. west nile virus and eee are pending at the time of this writing, but are no longer suspected given the pt's history. empiric acyclovir was discontinued when hsv pcr returned negative as well. the patient was discharged on po clinda and cefpodoxime to complete a 14 day course of treatment for aspiration pneumonia given the severity of his clinical picture. when the patient was transferred to floor and his mental status was appropriate for conversation, he was seen by our addictions specialist. several members of our team also spoke at length with about quitting his alcohol and drug abuse. quite frankly, it is rather remarkable that he did not sustain anoxic brain damage during his course. long term pulmonary and cognitive follow up will be key in order to document whether long term sequellae ensue. moving forward, his new pcp, . , can consider at a later date whether pfts or neurocognitive testing are indicated, especially in view of his long term plans to work as a mechanic for the airforce. he states that this will be difficult for him given the group of friends he has, however he plans to leave for the air force in . he was given pamphlets and phone numbers for various addiction hotlines and services. he also does not have a primary care doctor and was given a follow up appointment with dr. in clinic in 2 weeks. medications on admission: no regular medications pt reports taking 20 klonopin +/- alcohol before
