Clinical Trial Controlled Clinical TrialCytokine levels in cerebrospinal fluid and delayed ischemic deficits in patients with aneurysmal subarachnoid hemorrhage.
Subarachnoid hemorrhage (SAH) induces an inflammatory reaction and may lead to ischemic brain damage. The pathogenesis of brain dysfunction and delayed ischemic symptoms remain difficult to understand despite extensive surveys of such reactions. Cytokine production in the central nervous system following SAH and its relation with clinical outcome have hardly been studied. ⋯ The patients with poor neurological status showed high levels of IL-1 beta, and IL-6. The patients who developed delayed ischemic deficit had high level of IL-6. We suggest that elevated level of IL-6 in cerebrospinal fluid of patients with aneurysmal SAH on admission can predict the high risk of delayed ischemic deficit.

Case ReportsRecurrent pseudotumor cerebri in systemic lupus erythematosus: a case report.
Pseudotumor cerebri is an uncommon manifestation of neuropsychiatric systemic lupus erythematosus (SLE), and is characterized by an elevated intracranial pressure, papilledema with occasional abducens nerve paresis, absence of a space-occupying lesion or ventricular enlargement, and normal cerebrospinal fluid chemical and hematological constituents. Pseudotumor cerebri has been reported in a few sporadic cases in patients with systemic lupus erythematosus. However, the recurrent pseudotumor cerebri in patients with systemic lupus erythematosus which has been rarely reported, has not been reported in Korea. ⋯ She was diagnosed pseudotumor cerebri twice and successfully treated with corticosteroid. Headache is the common symptom in patients with neuropsychiatric SLE and attributable to various causes. We suggest that it is important to define the cause of headache in patients with SLE and pseudotumor cerebri should be included in the spectrum of clinical manifestations during the course of SLE as a cause of headache.

Nurses' assessment of postoperative pain: can it be an alternative to patients' self-reports?
This study was designed to evaluate whether the nurses' assessment of postoperative pain can be an alternative to patients' self-reporting. We examined 187 patients receiving postoperative intravenous patient-controlled analgesia. The nurses assessed the patients' pain with three pain indices (therapeutic efficacy, pain intensity, and facial pain expression) 8 hr after operation. ⋯ The pain intensity assessed with a simple verbal descriptor scale therefore is believed to be an effective alternative to the patients' self-reports of postoperative pain at rest. However, it mirrored the patients' self-reports during movement less reliably. Therapeutic efficacy and facial pain expression indices were not effective alternatives to patients' self-reporting.

The flow rate of the elastomeric balloon infusor is influenced by the internal pressure of the infusor.
The purpose of this study was to evaluate the flow rate of elastomeric balloon infusor composed of rubber or silicone materials. Two models were studied: the Baxter Twoday Infusor and Advance Silicone Infusor. Each infusion device has a preset flow rate of 2 mL/hr. ⋯ Both devices initially infused at a relatively high rate, followed by a somewhat steady flow rate. The flow rate distinctly increased in the small residual volume. The flow rate of the balloon infusor used in this study was not sustained uniformly during the entire delivery period and was in proportion to the internal pressure of the infusor regardless of the materials.

ReviewChemistry and cancer preventing activities of ginseng saponins and some related triterpenoid compounds.
More than 25 dammarane-type tetracyclic triterpenoid saponins have been isolated from ginseng, the root and rhizome of Panax ginseng C. A. Meyer (Araliaceae). ⋯ Recently, ginsenoside Rg-3 was produced as an anti-angiogenic anti-cancer drug in China. The aforementioned reports suggest that less glycosylated protopanaxadiol derivatives are effective in cancer prevention. Apart from Ginseng tetracyclic triterpenoid saponins, some oleanane-type pentacyclic triterpenoid compounds showed the anti-carcinogenic activity in the two-stage anti-cancer-promotion experiments in vitro and in vivo.
