Safety of high-dose iron sucrose infusion in hospitalized patients with chronic kidney disease.

PURPOSE: The safety of high-dose iron sucrose infusion in hospitalized patients with chronic kidney disease was studied. METHODS: A retrospective analysis was conducted at a 478-bed community hospital. A medical informatics search was performed to identify all hospitalized patients who were prescribed i.v. iron sucrose to deliver elemental iron 300 mg every other day for three doses between January and December 2002. Patients were eligible for inclusion in the analysis if they had chronic kidney disease, had an estimated creatinine clearance of <60 mL/min, and were prescribed the above regimen. Information on iron administration, vital signs, hematologic values, and iron indexes was gathered from patients' medical records. Medical record review was also used to identify possible adverse events. RESULTS: A total of 73 patients met eligibility criteria and received a total of 167 doses of iron sucrose. Twenty adverse events were judged as possibly related to iron sucrose administration and included nausea (n = 8 events), reduced blood pressure (n = 4), vomiting (n = 2), dysgeusia (n = 2), constipation (n = 2), fatigue (n = 1), and anxiety (n = 1). The majority of these adverse events were low in severity, as determined by an objective scale. No severe adverse events occurred. There was no association between infusion rate and the occurrence of potential adverse events (p = 0.44). CONCLUSION: Every-other-day i.v. infusion of iron sucrose, to deliver elemental iron 300 mg/dose, was associated with adverse events that were relatively uncommon, minor in severity, and unlikely to require medical intervention.

Compression of the rostral ventrolateral medulla by a vagal schwannoma of the cerebellomedullary cistern presenting with refractory neurogenic hypertension: case report.

OBJECTIVE: The rostral ventrolateral medulla is thought to serve as a final common pathway for the integration of central cardiovascular information and to be important for the mediation of central pressor responses. An association between essential hypertension and neurovascular compression of the rostral ventrolateral medulla has been reported. This may be mediated by an increase in sympathetic tone. CLINICAL PRESENTATION: Schwannomas arising from the lower cranial nerves (Cranial Nerves IX-XI) are rare, constituting only 3% of all intracranial schwannomas unassociated with neurofibromatosis. The majority of these tumors present as jugular foramen lesions and, less commonly, they occur along the extracranial course of these nerves. An intracisternal location is extremely rare. Fewer than 15 cases of pathologically proven intracisternal vagal schwannomas in the absence of neurofibromatosis have been reported. INTERVENTION: We report a case of vagal schwannoma in the cerebellomedullary cistern causing distortion of the vagal root entry zone and presenting with refractory neurogenic hypertension. Total microsurgical excision of this tumor, arising from one of the rootlets of the vagus nerve, was achieved. Immediately postoperatively, blood pressure decreased markedly, and despite our effort to maintain the blood pressure with fluids, the patient developed a cerebral infarction in the watershed zone. CONCLUSION: We discuss the proposed mechanism of hypertension, and the perioperative management, stressing blood pressure control. A review of the literature regarding vagal schwannomas is also presented. To the best of our knowledge, this is the first case report of a cerebellomedullary cistern vagal schwannoma presenting with neurogenic hypertension.

Using data to make decisions: planning HIV/AIDS care under the Ryan White CARE Act.

This article describes the challenges of using data to plan and fund HIV/AIDS care services for underserved populations under the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act. It also outlines methods that have been developed by the Health Resources and Services Administration of the U.S. Department of Health and Human Services to assist community planning groups in using data to decide how to target limited federal resources under the CARE Act. Use of CARE Act dollars is guided largely by an array of legislatively identified priority areas, such as targeting of low income HIV-infected individuals who are not in care for their HIV disease. CARE Act program guidance covers the use of epidemiologic HIV and AIDS case data, quantification of unmet need for HIV care, guidance on making objective decisions on priorities for funding within a community planning process, and other instructions on the use of data in making decisions.
