Valve-sparing root replacement after the Ross procedure.

Objectives: The Ross procedure is a preferred treatment for infants and children with aortic valve disease. Progressive neoaortic root dilation and neoaortic insufficiency can occur after the Ross procedure, and because of the young age of these patients, valve-sparing aortic root replacement procedures have advantages compared with the Bentall procedure. The aim of this study is to describe our experience with different techniques of aortic valve-sparing root replacement in this unique cohort of patients.

Pulse oximetry index: a simple arterial assessment for patients with venous disease.

Objective: To provide additional safety data comparing ankle brachial pressure index (ABPI) and pulse oximetry (Lanarkshire Oximetry Index, LOI) as measures of arterial circulation in patients with venous disease of the leg.

Method: A total of 107 (195 legs) attending hospital leg ulcer clinics participated in this prospective open study. We attempted to measure brachial and foot arterial pressures in all patients using both the handheld Doppler method (ABPI) and pulse oximeter method (LOI).

Erosive pustular dermatosis of the leg associated with compression bandaging and fungal infection.

Background: Erosive pustular dermatosis of the leg (EPDL) has been described in association with venous insufficiency and atrophy of the skin of the lower leg. Like erosive pustular dermatosis of the scalp, this disease has also been reported to be a non-infective condition.

Objectives: To investigate the clinicopathological features and, where possible, the aetiology of clinical EPDL.

Pulse oximetry: a new tool to assess patients with leg ulcers.

The objective of the study was to investigate pulse oximetry as a guide to assessing patients with leg ulcers before treatment. Graduated elastic compression is the treatment of choice for uncomplicated venous leg ulcers, but is contra-indicated in patients with significant arterial disease. The standard assessment of arterial insufficiency by Doppler ultrasound ankle branchial pressure index (ABPI) has shortcomings which prompted this investigation of pulse oximetry as a possible additional, or alternative, method of assessment of patients with leg ulcers, prior to treatment with compression.

Anemia.

Purpose/objectives: To review the current knowledge of anemia associated with cancer management and nursing interventions.

Data Sources: Published theory, research, and clinical practice sources.

Data Synthesis: Anemia often is overlooked as a priority associated with quality patient care.

An electroretinogram protocol for toxicological screening in the canine model.

A five-step electroretinogram protocol was developed for the dog to be used as a painless screening test for ocular effects of drugs or pesticides. Standard conditions of frequency band width, stimulus intensity, dark adaptation time and non-confounding anesthesia method were selected to allow analysis of wave components. The protocol demonstrated an acceptable level of inter-subject variability for compiling an age appropriate database, and for the detection of possible retinal component toxicities in chronic dog studies.
