This is a case of a ventricular tachycardia, likely from myocardial ischemia or infarction. Ventricular tachycardia is a life-threatening irregularity of the heart’s conduction system, which is often caused by reduced blood fow to the heart. The patient’s symptoms of palpitations, nausea, and dizziness occurred spon-The patient’s symptoms of palpitations, nausea, and dizziness occurred spon- taneously, awaking him from sleep. This patient’s ventricular tachy- cardia is refractory to amiodarone and will persist regardless of treatment (even treatment with lidocaine or procainamide). Eventually, the patient becomes unstable with chest pain, altered mental status, and hypotension. Without syn- chronized cardioversion (shock) at this point, the patient will become pulse- less. Myocardial ischemia decreases the homogeneity of left ventricular depolar- ization and repolarization that can cause reentry and sustained ventricular tachyarrhythmias. Defbrillation and cardioversion simultaneously depolarize all cardiac tissue and terminate any sites of reentry causing all cardiac cells to be in the same depolarized state. Patient appears stated age, drowsy but arousable to painful stimuli, supine on stretcher, vomitus noted on clothes. Patient initially was nauseous, then vomited twice and doesn’t remember what occurred following. Boyfriend admits to an argument taking place, states he left the patient in the bedroom after the argument but then was concerned when she did not come out after some time. He reports the patient was found in bed upon reentering bedroom, attempted to wake her up, at which time the patient developed a generalized tonic-clonic seizure lasting less than 1 minute. Social: denies alcohol use, smoking, and illicit drug use; lives with boyfriend in apartment; sexually active without protection with boyfriend g. Abdomen: mildly tender in epigastrium, bowel sounds signifcantly decreased, no masses, no hernias, nontender at McBurney’s, negative Murphy’s sign, no rigidity l. Patient: still drowsy, has repeat generalized tonic-clonic seizure lasting 30 seconds K. In this patient, the symptoms of nausea, vomiting, mental status changes, and sei- zures began within 2 hours of amitryptyline ingestion signifying a large dose or coingestion of another drug. Once the patient is stabilized, activated charcoal can be considered for gastro- intestinal decontamination. Other than mild generalized malaise, he denies any other symptoms such as nausea, vomiting, diarrhea, dysuria, frequency, headaches, cough, rhinor- rhea, vision complaints, or neurological symptoms. Social: married with 2 children, denies alcohol, smoking, or recreational drugs g. Eyes: extraocular movement intact, pupils equal, reactive to light, icteric sclera d. Abdomen: surgical incision well-healed, moderate diffuse tenderness, ascites present with distension. Abdominal paracentesis: cell count with differential, glucose, protein, Gram stain, and culture b. This is a case of a fever in a posttransplant patient, which is a serious concern because these patients are on multiple medications to suppress their immunity and are at high risk for serious infections. The patient’s symptoms of fevers, abdominal pain, ascites, and malaise began 4 days before evaluation.

Any translocation of water The brain is the target organ for dysnatremia and results from electrolyte transmembrane exchange. The realization led to the concept of electrolyte free water generation and persistence of the water abnormali- clearance (Ce ) to estimate translocation of water. H2O ties seen in dysnatremia are, however, dependent on Electrolyte free water clearance is calculated by modi- changes in renal function or renal free water clearance. Classification of dysnatremic states is based on body Free water clearance, weight, volume status, and osmolar status [7, 19, 44]. Hyperosmolar hyponatremia occurs in severe hyperglycemia or after exposure to mannitol, ethanol, Electrolyte free water clearance, or methanol. Thus, clinical history, physical exam, Ce will be negative with water retention and posi- and consideration of changes in weight are key initial H2O tive with losses of free water.

Initial use may result in stimulatory effects viagra 25 mg sale impotence quitting smoking, such as increased confidence generic 50 mg viagra free shipping erectile dysfunction za, decreased fatigue, heightened motivation, agitation, irritability, and insom- nia, which may progress to argumentative and aggressive behavior and major mood disturbances including depression, mania, and hypomania (90,91). Other Body-Building Drugs Other drugs may be used by body builders (93), including tamoxifen to reduce or prevent gynecomastia; diuretics to counteract the fluid retention caused by anabolic steroids; thyroxine to increase the rate of metabolism, which might theoretically increase the ability of anabolic steroids to boost physical strength (94); and β human chorionic gonadotrophin to alleviate testicular atrophy (95). Nalbuphine (Nubain) is an opioid agonist/antagonist analgesic used for the treat- 304 Stark and Norfolk ment of moderate-to-severe pain, and dependence has been reported associated with anabolic steroid use (96). Furthermore, there has been a case report of a 21-year-old body builder who was admitted after taking excessive amounts of insulin intravenously; apparently, insulin is advertised in body-building magazines as having ana- bolic properties (97). The recreational use of caffeine to toxic levels has been reported in a body builder who presented with a grand mal seizure (98). Clenbuterol, which is a sympathomimetic agonist (used as a oral bronchodila- tor in some European countries but not licensed for human use in the United Kingdom or United States) is said to have an “anabolic-like” effect but at high dose may cause cardiac dysrhythmias, tremor, and serious hypokalemia (99). It has been used as an anesthetic (although it has little analgesic effect), to alleviate narcolepsy, and to treat alcohol and opiate dependence (101). There have been reports of abuse in the United Kingdom and United States within the dance scene and gay clubs and with body builders because it is said to promote slow-wave sleep during which growth hormone is secreted (102). It is available as a color- less, odorless liquid, powder, or a capsule to be taken orally; it is rarely injected. It has a half-life of 30 minutes (103), and effects can last from 45 minutes to 8 h (104). Initial effects include euphoria followed by profound sedation, confu- sion, agitation, amnesia, nausea, vomiting, diarrhea, ataxia, seizures, hypoto- nia, tremor, vertigo and dizziness, bradycardia, hypotension, hypothermia, coma (105), and respiratory collapse. Tolerance and physi- cal dependence after high-dose use can develop with a withdrawal syndrome, which may include insomnia, muscular cramping, tremor, and anxiety (101). A rapid deterioration into delirium may occur in more frequent high-dose dependent users. Withdrawal is not associated with seizures, but if suspected, hospital admission should be considered (108). Ketamine Ketamine is a commercially available anesthetic for intravenous and intra- muscular use. It contains analgesic properties and is available on the street in Substance Misuse 305 powder, tablet, and liquid form; it can be smoked or taken intranasally (“snorted”), orally, intramuscularly, or intravenously (109). The onset of effects depends on the route of administration; when taken orally, effects start within 20 minutes and can last up to 3 hours, whereas given intravenously, effects will be seen within 30 seconds and last about 30 minutes (110). Physical effects may include a cocaine-like “rush,” hypertension, dysrhythmias, nausea, and vomiting, slurred speech, nystagmus, lack of coor- dination, and seizures. On recovery, “emergence phenomena” may occur, with psychological dissociation or out of body (flying or floating) sensations, con- fusion, hallucinations, synesthesia, and depersonalization (112). Such disso- ciative states may result in the individual becoming divorced from reality, and these effects, coupled with possible loss of coordination and pronounced anal- gesia, can result in serious accidents to users. A dose-dependent depression of respiration may occur (113), and this can be a particular problem when taken with other respiratory depressant drugs, such as benzodiazepines and alcohol, occasionally resulting in death (114). Alkyl Nitrites The alkyl nitrites are volatile yellowish clear liquids that have a distinc- tive sweet smell. All the nitrites have vasodilatory properties and are used as a euphoric relaxant within the dance culture and to relax the anal sphincter and enhance sexual performance.
