Pituitary apoplexy indicates pituitary adenoma hemorrhage, which could result in acute pituitary insufficiency and mortality. The typical symptoms are headache, visual disturbance, nausea, vomiting, altered mental status, and panhypopituitarism. However, cortisol-induced hyperglycemia and acute delirium could be an initial presentation of a pituitary adenoma hemorrhage with stormy release of the adrenocorticotrophic hormone. A 28-year-old woman presented with severe vomiting, irritable state, and delusion. She had medical history of irregular menstrual cycles and marked body weight gain after her second childbirth 8 years ago. She was diagnosed of diabetic ketoacidosis 2 days before this visiting at local medical department. On physical examination, Cushing appearance without definite neurological deficit was disclosed. Further blood tests revealed high blood sugar, cortisol, and adrenocorticotrophic hormone levels without evidence of diabetic ketoacidosis. The brain computed tomography and magnetic resonance imaging showed pituitary macroadenoma and pituitary hemorrhage. Cushing disease with pituitary apoplexy was then diagnosed. Conservative management with delayed neurosurgery was applied. The patient became clear with normalized cortisol and blood sugar levels soon after. Follow-up computed tomography scan of the brain revealed no progression of tumor bleeding or mass effect. To our knowledge, pituitary apoplexy associated with cortisol-induced hyperglycemia and acute delirium has never been reported before. This case reminds us of pituitary apoplexy and its rare manifestations.

Palliation of symptoms to optimize QOL is the foundation of cancer care regardless of stage of disease or level of anticancer treatment. Patients commonly experience pain, constipation, nausea, vomiting, dyspnea, fatigue, and delirium. Many valid clinical tools are available to the primary care clinician to screen for symptoms, assess severity, measure treatment response, and elicit the patient's subjective symptom experience. Although there is limited evidence regarding the relative efficacy of symptom interventions from randomized controlled trials, clinical practice guidelines are available.

Aspirin should not be used to treat acute febrile viral illness in children. (Strength of Recommendation [SOR]: C, based on case-control studies). Although no causal link has been proven, data from case-control and historic cohort studies demonstrate an association between aspirin use and Reye syndrome. The risk of Reye syndrome decreases with age, becoming extremely rare by the late teenage years. Other nonsteroidal anti-inflammatory drugs are effective antipyretics and are not associated with the constellation of symptoms seen in Reye syndrome, which includes nausea, vomiting, headache, excitability, delirium, combativeness, and coma. Aspirin use in children younger than 19 years should be limited to diseases in which aspirin has a proven benefit, such as Kawasaki disease and the juvenile arthritides. (SOR: C, based on expert opinion).

Delirium may present with hyperactive, hypoactive or mixed clinical pictures. The signs of hypoactive delirium are lethargy, confusion, apathy, hypersomnia, muttering, difficulty in maintaining attention, and difficulty in understanding and performing commands. Valproate is commonly used for the treatment of epilepsy and bipolar disorders. It is also used for the management of alcohol withdrawal delirium and agitative-aggressive deliriums. However, few reports are available about the valproate-induced delirium. In this report, we present a 46 years-old woman with bipolar disorder for 14 years. During her last two hospital admissions, she had been diagnosed with manic episode with psychotic features and she had received valproate. She experienced three hypoactive delirium episodes lasting 2-3 days throughout the treatment period of first week. The patient predominantly had the following signs; vomiting, hypersalivation, confusion, drowsiness, dysphasia, and hypoactivity. At the first day of delirium episode, serum valproate level was found to be within the therapeutic range (98.4, 117.1, and 65.6 mug/ml; respectively). In addition, she had normal results of cranial MRI, complete blood count, urine analysis, electrocardiogram, ALT, AST, albumin, bilirubin, BUN, creatinine and electrolytes. The serum ammonia level of the patient could not been measured due to limitations of laboratory facilities. The patient's consciousness improved dramatically 2-3 days after cessation of valproate. In conclusion, valproate can induce delirium at therapeutic blood levels in some patients via various mechanisms and this side effect has to be considered during valproate use.

Understanding the particular pharmacology of different antidepressant drugs can help explain their adverse effects when they are discontinued. For all antidepressant drugs, abruptly stopping them can sometimes result in "rebound" hypomania or mania. Antidepressant drugs having anticholinergic effects often are associated with a discontinuation syndrome characterized by cholinergic rebound, with symptoms of nausea, vomiting, abdominal cramping, sweating, headache, and muscle spasms. Discontinuation of monoamine oxidase inhibitor drugs sometimes results in flu-like symptoms, dysphoria, restlessness, tachycardia, hypertension, and a delirium-like state. Serotonergic antidepressant drugs are sometimes associated with a distinct discontinuation syndrome characterized by dizziness, weakness, nausea, headache, lethargy, insomnia, anxiety, poor concentration, and paresthesias. Adverse discontinuation effects can occur with all types of antidepressant drugs, but only rarely would they be considered serious. To minimize adverse discontinuation effects and to reduce the risk of relapse or recurrence of the underlying treated condition, tapering antidepressant medication is prudent for all patients.

Acute encephalitis/encephalopathy is a life-threatening disease, and early diagnosis is important. The acute encephalitis/encephalopathy is characterized by impaired consciousness, delirium, convulsion, pyrexia, vomiting, headache, paralysis and so on. We need to distinguish various diseases with similar symptoms, such as febrile seizure, bacterial meningitis, acute disseminated encephalomyelitis, cerebrovascular disease, non-convulsive status epilepticus, benign convulsion with gastroenteritis, hypoglycemia, inherited metabolic disease, toxicosis, heat attack, somatoform disorder and so on, from acute encephalitis/encephalopathy. We describe the features of these diseases in point of view with difference from acute encephalitis/encephalopathy. A synthetic and prompt evaluation including medical interview, neurological sign, blood examination, computed tomography, magnetic resonance imaging, spinal fluid examination, electroencephalogram, is necessary to diagnose as acute encephalitis/encephalopathy.

Acute delirium is a commonly encountered problem in the intensive care unit (ICU), which has a myriad of causes and contributes to poor outcomes. We present the case of an alcoholic critically ill patient who developed prolonged acute ICU delirium wrongly diagnosed as sedation and alcohol withdrawal. Protracted vomiting, swallowing disorders and continuous aspirations prevented him from enteral feeding and discontinuation of mechanical ventilation. After several days, it became clear that the patient had been misdiagnosed. Fortunately, nystagmus and ophthalmoplegia then allowed the recognition of Wernicke's encephalopathy, confirmed by cerebral MRIs. After thiamine supplementation, his state improved but he was discharged only on day 32. Wernicke's encephalopathy is an acute reversible neuropsychiatric emergency, which is falsely considered as uncommon, and is largely misdiagnosed, especially in critically ill patients. Thiamine should be systematically given to all critically ill alcoholic patients, especially those with protracted vomiting.

Hypercalcemia occurs in 10% to 20% of those with advanced cancer. It is considered an oncologic emergency. Presenting symptoms include common gastrointestinal symptoms that may be difficult to differentiate from tumor or treatment-related symptoms. These include nausea, vomiting, and constipation. As levels increase or if development is rapid, neuropsychiatric symptoms such as delirium can develop. Untreated it will lead to coma and death. Current preferred therapies are the bisphosphonate agents, zoledronate and pamidronate with saline rehydration.

Postoperative delirium is one of the most spectacular, frightening and misdiagnosed postoperative complications of surgery. We describe the case of a caucasian 77-year-old male patient, who developed a severe postoperative delirium after combined transurethral resection of the prostate and cystolithotripsy. This systemic and unpredictable complication of endoscopic surgery is caused by excessive absorption of electrolyte-free irrigation fluids, leading to brain edema and metabolic encephalopathy. The clinical spectrum ranges from asymptomatic hyponatraemia, to electrocardiographic (ECG) changes, nausea, vomiting, convulsions, coma, pulmonary edema, cardiovascular compromise and death. Because of the heterogeneous clinical presentation diagnosis can be difficult. In a patient who develops alterations of consciousness with evidence of hypervolemia and hyponatremia after endoscopic surgery, transurethral resection syndrome must be considered.

Acute intermittent porphyria (AIP) is a rare autosomal dominant disorder of heme biosynthesis in liver due to deficiency of porphobilinogen deaminase enzyme. Clinically, AIP is dominated by a colicky type pain, which does not subside after taking usual analgesics. Additional frequent symptoms are vomiting, hypertension, peripheral neuropathy, seizures, depression, delirium and coma. This paper reported a case of a twenty-five- year-old female patient, who had undergone a period of six days between the first presentation to the medical department and the diagnosis confirmation. It has accentuated possible mistakes in symptomatic therapy administration as well as dangers of a delayed diagnosis.
