Helium microwave-induced plasma mass spectrometric detection for reversed-phase high-performance liquid chromatography.

Reversed-phase high-performance liquid chromatography (HPLC) is directly coupled to helium microwave-induced plasma mass spectrometry (He MIP-MS) for the element-selective detection of halogenated organic compounds. Absolute detection limits are approximately 50 pg Br for brominated compounds, 1 pg I for iodinated compounds, and 10 ng Cl for chlorinated compounds. The linear dynamic range for Br- and I-containing compounds is 3-4 orders of magnitude. However, the linear range for chlorinated species is severely limited by high background at m/z = 35. The relative standard deviation for repetitive injections is less than 10%. The helium microwave-induced plasma is operated at moderate powers (300-350 W) and with a total helium consumption of 6-8 L/min. The effect of organic solvents on the background mass spectrum is investigated.

Inductively coupled plasma mass spectrometry and atomic emission spectrometry coupled to high-performance liquid chromatography for speciation and detection of organotin compounds.

Inductively coupled plasma mass spectrometry (ICP/MS) is utilized as a detector for several organotin species separated by high-performance liquid chromatography. Detection limits obtained by ICP/MS are 3 orders of magnitude lower than those obtained with inductively coupled plasma atomic emission spectrometry (ICP/AES) detection under the same chromatographic conditions. Chromatographic detection limits are higher than conventional solution nebulization for the same compound by a factor of 20. Ion-exchange chromatography yields linear response over 3 orders of magnitude, while ion pair chromatography gives a linear response of only 2 orders of magnitude as a result of poor resolution. The relative standard deviation for the injection of 20 ng of tin compounds is less than 10%.

Analysis and significance of nosocomial infection rates.

An analysis of the systems of nosocomial infection reporting utilized in a 332 bed, urban, referral-type hospital demonstrated that physician reporting was much less reliable than a well-planned surveillance system coordinated by an infection control nurse. During 12 months' experience with the most recently devloped system, the average monthly rate of nosocomial infection was 10.7%. A prevalence survey gave a rate of 14.4%. The efficiency of reporting was close to 100% when the infection control nurse spent 100% of her time on surveillance. With a reduction in surveillance time to 75%, the efficiency of reporting fell to about 75%.

A weekend camp for bereaved siblings.

PURPOSE: The purpose of this article is to describe a weekend bereavement camp for children age 6 to 18 years who have lost a brother or sister to cancer. A description of the planning for the camp and the weekend program is included. OVERVIEW: Camp New Horizons is a weekend camp for children age 6 to 18 years who have lost a sibling to cancer. At the camp, the children are divided into age-appropriate groups and spend time, through various activities, learning about the grief process to reduce their feelings of isolation, to express grief appropriately, and to move forward in the grief process. Similar programs, as well as the uniqueness of this program, are discussed. CLINICAL IMPLICATIONS: Camp New Horizons has met many of the educational and support needs of bereaved siblings. Networks of support and friendship have formed that allow the children to reach out to one another when needed. Parents and children have increased their communication about the death in their family, thus accepting their feelings and increasing support in the family system. Continued collaboration between centers will create ongoing support for the healthcare professionals and the programs they provide.

Alzheimer's disease 2: Caring for a woman with Alzheimer-type dementia.

Alzheimer's disease creates difficulties in perceiving and interpreting information for an individual. Nursing care must be sensitive to this. A comprehensive nursing assessment should include information about how the patient performed functionally and psychologically before the illness, and what these abilities are like on admission. This allows for achievable goals in care to be set. Although patients are cognitively impaired they should be actively involved in their care along with their carers.

Aphasia: a care study.

Aphasia is a term used to describe any deficit in the production or comprehension of speech. Damage to various parts of the brain can give rise to aphasia. The communication problems experienced by patients with aphasia present a unique challenge to the nurse. It is vital that all patients receive a proper assessment of their needs. A holistic approach is required. Nurses should be non-judgmental in their approach and remember the person behind the aphasia.
