BACKGROUND: The pain that women experience during labour is affected by multiple physiological and psychosocial factors and its intensity can vary greatly.  Most women in labour require pain relief. Pain management strategies include non-pharmacological interventions (that aim to help women cope with pain in labour) and pharmacological interventions (that aim to relieve the pain of labour). OBJECTIVES: To summarise the evidence from Cochrane systematic reviews on the efficacy and safety of non-pharmacological and pharmacological interventions to manage pain in labour.

ETHNOPHARMACOLOGICAL RELEVANCE: Ayurveda has its unique perceptions and resultant methodologies for defining and treating human diseases. Fumigation therapy is one of the several treatment methods described in Ayurveda whereby fumes produced from defined drug formulations are inhaled by patients. This therapeutic procedure offers promising research opportunities from phytochemical and ethnopharmacological viewpoints, however, it remains under-noticed.

Some patients are anxious about routine dental treatment; others, who may be able to cope with uncomplicated treatment, are worried by more unpleasant procedures such as minor oral surgery. Management approaches to anxiety vary according to its severity, the age of the patient, the degree of cooperation and the patient's medical history. Psychological approaches have been widely used and range from informal and common-sense methods to formal relaxation training and hypnosis. These techniques are safe, free from adverse effects and give the patient a sense of control.

This article studies the problem of controlling the drug administration during an anesthesia process, where muscle relaxation, analgesia, and hypnosis are regulated by means of monitored administration of specific drugs. On the basis of a seventh-order nonlinear pharmacokinetic-pharmacodynamic representation of the hypnosis process dynamics, a cascade (master/slave) feedback control structure for controlling the bispectral index (BIS) is proposed.

OBJECTIVES: To assess the influence of 50% nitrous oxide (N2O) on the induction doses of propofol and thiopental by means of the auditory evoked potentials index (AAI). To evaluate the time to induction of anesthesia. PATIENTS AND METHOD: This was a prospective controlled trial in ASA 1-2 patients randomized to 4 groups for administration of propofol in 100% oxygen (group P1), propofol in a mixture of 50% N2O and 50% oxygen (group P2), thiopental in 100% oxygen (group T1) or thiopental in a 50% N2O and 50% oxygen mixture. An AAI monitor was used.

Difficult asthma is defined as the persistence of asthma symptoms, abnormal pulmonary function showing airway obstruction, and continued requirement for short-acting bronchodilator therapy, despite adequate treatment with inhaled corticosteroids. It calls for a thorough evaluation of the patient to look into alternate and complicating diagnoses. The authors report a case of a 9-year-old patient with difficult asthma who failed to respond to conventional therapy.

The host immune response contributes to the onset and progression of severe malaria syndromes, such as cerebral malaria. Adjunctive immunomodulatory strategies for severe malaria may improve clinical outcome beyond that achievable with artemisinin-based therapy alone. Here, we report that prophylaxis with inhaled nitric oxide significantly reduced systemic inflammation (lower TNF, IFN? and MCP-1 in peripheral blood) and endothelial activation (decreased sICAM-1 and vWF, and increased angiopoeitin-1 levels in peripheral blood) in an experimental cerebral malaria model.

Fragrance compounds and essential oils with sedative effects influence the motility of mice in inhalation studies under standardized conditions. A significant drop in the motility of mice was registered following exposure to these fragrances. The same results were achieved when the mice were artificially induced into overagitation by intraperitoneal application of caffeine and subsequently subjected to inhalation of fragrance compounds and essential oils. These results proved the sedative effects of these fragrants via inhalative exposure in low concentrations.
