Benchmarking in national health service procurement in Scotland.

The paper reports the results of a study on benchmarking activities undertaken by the procurement organization within the National Health Service (NHS) in Scotland, namely National Procurement (previously Scottish Healthcare Supplies Contracts Branch). NHS performance is of course politically important, and benchmarking is increasingly seen as a means to improve performance, so the study was carried out to determine if the current benchmarking approaches could be enhanced. A review of the benchmarking activities used by the private sector, local government and NHS organizations was carried out to establish a framework of the motivations, benefits, problems and costs associated with benchmarking. This framework was used to carry out the research through case studies and a questionnaire survey of NHS procurement organizations both in Scotland and other parts of the UK. Nine of the 16 Scottish Health Boards surveyed reported carrying out benchmarking during the last three years. The findings of the research were that there were similarities in approaches between local government and NHS Scotland Health, but differences between NHS Scotland and other UK NHS procurement organizations. Benefits were seen as significant and it was recommended that National Procurement should pursue the formation of a benchmarking group with members drawn from NHS Scotland and external benchmarking bodies to establish measures to be used in benchmarking across the whole of NHS Scotland.     

Gastric Epithelioid Leiomyosarcoma: A Curable Gastric Neoplasm

This is the first case report of the preoperative diagnosis of a gastric epithelioid leiomyosarcoma by percutaneous needle biopsy. Preoperative diagnosis facilitated curative surgical resection. Patients may present without symptoms or may report symptoms of peptic ulcer disease or gastrointestinal bleeding. Upper gastrointestinal series is the most useful radiological tool for detecting these lesions. Ultrasound and CT play a useful role in documenting the origin of these large masses, as well as their spread. Endoscopy is being used with increasing frequency, but because these are submucosal lesions diagnosis cannot easily be made through the endoscope. Pathologically, these tumors can be subdivided histologically into a benign epithelioid leiomyoma and two varieties of malignant epithelioid leiomyosarcoma. Prognosis correlates with histological features. Complete surgical resection is the treatment of choice. Chemotherapy or radiotherapy have no proven efficacy in treating epithelioid leiomyosarcoma. Unlike most other gastric malignancies, a favorable prognosis follows successful resection.     

Kinetics and specificity at the clonal level of the cytotoxic T lymphocyte response to influenza pneumonia

We have studied the kinetics and specificity of the cytotoxic T lymphocyte (CTL) response to influenza A/PR/8 (H1N1) virus pulmonary infection in the mouse detected using spleen cells from infected mice which were stimulated in bulk and limiting dilution cultures. A hybrid protein designated D-peptide, which contains the terminal 157 amino acids of the HA2 subunit of A/PR/8 virus, was used to stimulate influenza virus subtype-specific secondary CTL in vitro. Infection induced two specificities of precursor CTL, cross-reactive and subtype-specific. The kinetics of the subtype-specific CTL response detected by the D-peptide were similar to the cross-reactive CTL response detected by stimulation with live virus. The majority of the precursor CTL (CTL-p) are able to lyse virus-infected target cells in a cross-reactive fashion. The number of memory subtype-specific and cross-reactive CTL increased by approximately 2.5 logs10 during the first 3 weeks after infection.     

Asystole from tetanic stimulation of the accessory nerve

An asystolic cardiac arrest is reported which occurred at the same time as supramaximal tetanic stimulation over the accessory nerve in order to evoke contractions in the trapezius and sternocleidomastoid muscles. The cause may have been the inadvertent stimulation of one or more of the cranial nerves of the carotid sheath at the base of the skull: the cranial root of the accessory nerve, the vagus, the sino-carotid branch of the glossopharyngeal nerve or the hypoglossal nerve. The most likely culprit, if not the vagus itself, was the cranial root of the accessory nerve which both functionally and anatomically should be seen as an integral part of the vagus. It is suggested that stimulation of any nerve in the carotid sheath should be approached with caution and that a tetanic stimulus to this area might best be avoided.     

Priapism Following Trazodone Overdose with Cocaine Use

Priapism is a urologic disorder and medical emergency with a variety of known etiologies including the use of psychotropic medications. The antidepressant trazodone is the agent most frequently implicated in the precipitation of priapism. Additionally, a number of drugs of abuse including marijuana, ethanol, and cocaine have been known to cause the disorder. It is unknown if drugs may act in an additive or a synergistic manner to cause priapism. We report a case of priapism which occurred following trazodone overdose in an individual actively using cocaine. This case suggests that combined trazodone and cocaine use may pose an additional risk of priapism. Since trazodone is commonly employed as a hypnotic and often chosen for polysubstance abusers due to its low abuse potential, clinicians should be aware of the possible additive risk of priapism in this patient population.     

National Alliance for Oral Health Consensus Conference on Medically Necessary Oral Health Care: Legal issues

This paper examines medical malpractice law as it applies to medically necessary oral health care. The basic legal concepts and reported cases involving medically necessary oral health care are reviewed. It is concluded that dental professionals and consumer advocates must advance their educational and legislative advocacy efforts so that health professional colleagues and the public will become aware of the importance of these services and insurers will routinely include coverage of medically necessary oral health care in their medical and dental policies. While failure to provide medically necessary oral health care can be violative of patient rights and legally actionable, medical malpractice litigation should always be the behavior modifier of last resort.     

Euphorbia sap keratopathy: four cases and a possible pathogenic mechanism.

AIMS: To report four cases of Euphorbia sap causing anterior segment toxicity. METHODS: Medical records of four patients who presented with Euphorbia sap keratoconjunctivitis were reviewed. Clinical findings were compared with previously published reports. RESULTS: All of these patients experienced a similar clinical course. Initial contact with Euphorbia sap caused punctate epitheliopathy; patients noted immediate burning and photophobia, but no visual loss. In all cases, patients experienced epithelial slough with delayed healing, requiring approximately 9 days to heal the epithelial defect. Patients were treated with topical antibiotics, pressure patching or a bandage contact lens, and final visual acuities were excellent in all cases. A review of the literature revealed that Euphorbia sap contains a diterpenoid diester which exhibits antineoplastic activity in rodents. CONCLUSIONS: Individuals who work with Euphorbia plants should be cautioned to wear eye protection. Patients with Euphorbia sap anterior segment toxicity should be informed that their condition may worsen initially, but that visual outcome is generally excellent. The progressive corneal epithelial sloughing and delayed corneal epithelial healing may be secondary to the antineoplastic effects of Euphorbia sap.
