Personal history,training, and worksite as predictors of back pain of nurses

Back pain among nurses is a common problem. Prior studies of this problem have been based on cross-sectional or retrospective data. This 18-month prospective study involving nurses newly graduated from nursing school investigated personal, worksite, and training factors associated with future risk of back pain. Each nurse underwent a preliminary interview and periodic follow-ups to identify those with back injuries. Contingency tables and logistic regression analyses demonstrated that prior significant back pain episodes (evidenced by previous job changes because of back pain, frequent medication use, etc.) were associated with increased future risk. Training at nursing school or on the job did not have a protective effect. This pilot study therefore suggests factors useful in placement and counseling of new nurses and indicates the need for further implementation of mechanical lift assist device use. © 1994 Wiley-Liss, Inc.     

Genetic polymorphisms in dopamine-related genes and smoking cessation in women: a prospective cohort study

Background  

Genes involved in dopaminergic neurotransmission have been suggested as candidates for involvement in smoking behavior. We hypothesized that alleles associated with reduced dopaminergic neurotransmission would be more common in continuing smokers than among women who quit smoking.     

The Nurse Practitioner's Role

Decisional incapacity is the inability to make decisions for oneself caused by mental or physical impairment. With technologic advances in health care and the growing proportion of elderly in American society, the problem of decisional incapacity occurs more frequently. In the past, medical decision making was based on the principle of beneficence, and the judgment of others was used to determine medical interventions. The current trend is to base decisions as much as possible on the principle of patient autonomy. Advance directives allow for the greater use of this principle.
The primary care nurse practitioner (NP) can take an active role in promoting patient autonomy by helping the adult patient plan for decisional incapacity. By including the value history as a routine part of the health history, the NP can help patients identify their beliefs, values, and attitudes about health care. This documented value history can then be used to provide evidence of a patient's wishes should he or she become decisionally incapacitated.     

An effective treatment for functional urinary incoordination

Twenty women diagnosed with functional urinary incoordination were randomly assigned to one of two treatment groups: biofeedback or progressive muscle relaxation. Ten subjects who were placed on a waiting list prior to treatment allocation served as a comparison group. The biofeedback intervention focused specifically on retraining of pelvic floor musculature (PFM). Patients were assessed pretreatment, posttreatment, and at 2-month follow-up. Outcome measures included self-reported symptomatology, psychological functioning, psychophysiological assessment of the PFM, and urologist ratings of problem severity and treatment efficacy. Both treatment approaches proved effective in improving symptomatology and psychological state. Subjects on the waiting list demonstrated no change in urological difficulties. No differences were found between the two treatment groups on any of the outcome measures. Theoretical and practical implications of the results are discussed.     

Anaesthesia for Treacher Collins and Pierre Robin syndromes: A report of three cases

We present three patients with Treacher Collins or Pierre Robin syndromes who had historical and physical evidence of airway obstruction, difficulty feeding, and sleep disturbances. These preoperative findings correlated with difficult airway management intraoperatively. Based on this experience, we recommend that children with obstructive symptoms have laryngoscopy prior to anaesthetic induction. If the glottic opening is visualized, inhalational induction can proceed. If the glottic structures cannot be visualized, then the anaesthetist must choose between awake oral or nasal intubation, elective tracheostomy, or fiberoptic intubation. In all cases, a tracheostomy tray should be ready and a surgeon experienced in paediatric tracheostomy should be in attendance. After intubation, anaesthesia is best maintained with oxygen and a potent inhalational agent. Extubation should only be done with the patient fully awake and with emergency airway equipment immediately available. Postoperatively, these patients should be transferred to an intermediate care area or intensive care unit where they can be observed closely since delayed complications of airway obstruction are common in this group of patients.     

Plastic surgery for the management of palmoplantar keratodermia (Palmoplantoneoplasty)

Keratodermia is an incurable genetic and regional disease located in the palmar and plantar regions. The author reports his experience with five cases of palmoplantar keratodermia that were treated by grafting onto the soles and the palms skin taken from the calves and the thighs.     

Evidence-based medicine for nutrition support: an overview of the process.

On a daily basis, clinicians make decisions regarding therapies to result in the best outcome for their patients. These decisions should be based on the evidence in the literature, indicating a therapy will cause the best outcome. To facilitate this, many professional societies and scientific journals have published technical and scientific reviews, as well as evidence-based standards of care focused on many issues of nutrition support practice. This paper provides an overview of how these reviews and standards of care are derived to promote both the understanding of what they can and cannot do to enhance clinical practice.     

Mass spectrometric identification of urinary and plasma metabolites of 2-(6'-carboxyhexyl)-3-n-hexylcyclohexylamine, a new antiaggregating agent.

The compound IBI-P-05006, 2-(6'-carboxyhexyl)-3-n-hexylcyclohexylamine, is an antiaggregating agent under development. IBI-P-05006 is an in vitro inhibitor of platelet aggregation. The biotransformation of this compound has been studied in the dog and rat. We present here a study on the metabolites of IBI-P-05006 found in dog and rat urine, and in dog plasma. Analyses were done by gas chromatography-mass spectrometry. In dog urine 15 metabolites were identified. Some of them were also found in dog plasma and in rat urine. The unmetabolized drug was found only in plasma. 10 different hydroxylated metabolites were characterized. The hydroxyl groups were introduced in the hexyl chain in positions omega-4, omega-3, omega-2, omega-1 and omega.
