To review current concepts in the diagnosis of adrenocortical disease in the critically ill patient. ⋯ We suggest that the following caveats be borne in mind when diagnosing adrenal insufficiency in the critically ill patient. Firstly, the gold standard for the diagnosis has not been established. Secondly, caution must be exercised when interpreting a single plasma cortisol value. In the event of a single result indicating adrenal hypofunction, we suggest repeating the measurements after a 6 to 12 hour interval. The clinician must also be aware of variations in cortisol concentrations induced by the assay. Thirdly, the clinician must be aware of the potential limitations of the conventional high dose corticotrophin test. We also suggest that plasma free cortisol is more relevant than total plasma cortisol in the assessment of adrenal function in critical illness and that the low dose corticotrophin test is more sensitive than the conventional high dose test. These areas should be the subject of further investigations.

Continuous cardiac output measurement using pulse contour analysis is a technique gaining widespread acceptance in intensive care units. We report a case where a pulse contour analysis computer (PiCCO, Pulsion Medical Systems, Munich, Germany) failed to calibrate in a patient who was undergoing induced hypothermia for anoxic brain injury. ⋯ Subsequent rewarming of the patient allowed calibration of the arterial waveform and continuous cardiac output measurement. We were unable to find any previous reports of this problem using a PiCCO device, although similar problems with thermodilution cardiac output estimation using the pulmonary artery catheter during hypothermic cardiopulmonary bypass have been documented.

Partial seizures of extratemporal origin may present unique challenges in the patient with medically refractory seizures. The efficacy of an extratemporal focal cortical resection may be less effective than an anterior temporal lobectomy for intractable epilepsy. The potential operative complications may be increased in individuals with extratemporal epilepsy because of functional cerebral cortex involvement and the need for a large cortical resection to significantly reduce seizure tendency. ⋯ Chronic intracranial EEG monitoring may be necessary to confirm the localization of the ictal onset zone before epilepsy surgery. Patients with normal neuroimaging studies and extratemporal epilepsy are unlikely to be rendered seizure-free with focal cortical resection and should be considered candidates for other alternative forms of treatment for intractable partial epilepsy. Patients with non-substrate-directed extratemporal epilepsy should undergo a preoperative evaluation and surgical treatment at a comprehensive epilepsy center with extensive experience in chronic intracranial EEG monitoring and contemporary neuroimaging procedures because of the inherently high acuity associated with the operative management clinical disorder.

Why Taiwanese hospice patients want to stay in hospital: health-care professionals' beliefs and solutions.
Patient-related barriers and their solution in the planning of discharge to palliative home care were investigated through a nationwide survey conducted in Taiwan. Of 250 questionnaires sent to palliative care workers at 15 hospices in Taiwan, 229 valid questionnaires (91.6%) were retrieved. Most of the respondents were nursing staff (72.5%) while only 38 were physicians (16.6%). ⋯ The barriers and canonical loadings were: unable to manage emergent medical conditions (0.83), the quality of care in the hospital is better (0.74), and insufficient number of caregivers (0.72). The effective solutions that correlated significantly with the above factors were ranked as: to reassure the patient about the possibility of smooth readmission (0.84), to arrange palliative home care programs (0.68), and to educate family members on taking care of the patient at home (0.64). In conclusion, to solve patient-related barriers in the planning of the discharge of patients with terminal cancer, the results suggest that (1). health professionals involved in the care of patients with terminal cancer should have adequate knowledge of palliative care, particularly communication skills, (2). an effective referral system among general or oncology and palliative care units should be established, (3). inpatient care facilities and home-care programs should be provided, and (4). patients and families should be educated as to what may happen and how to manage these conditions at home and should be assured of the availability of medical help.

Diagnostic CT scans: assessment of patient, physician, and radiologist awareness of radiation dose and possible risks.
To determine the awareness level concerning radiation dose and possible risks associated with computed tomographic (CT) scans among patients, emergency department (ED) physicians, and radiologists. ⋯ Patients are not given information about the risks, benefits, and radiation dose for a CT scan. Patients, ED physicians, and radiologists alike are unable to provide accurate estimates of CT doses regardless of their experience level.
