Clinical Trial Controlled Clinical TrialEvaluation of alkalinized lidocaine solution in brachial plexus blockade.
The effect of alkalinization of lidocaine solution in brachial plexus blockade was evaluated in a double blind study. Commercial 1.5% lidocaine with epinephrine 1 : 200,000 (pH 5.72) was compared with an alkalinized solution of lidocaine (pH 7.12). 10 mg.kg(-1) of each solution was administrated by the axillary perivascular technique in 34 adult patients scheduled for elective surgery. The onset and spread of sensory blockade and the intensity of motor blockade were determined. ⋯ Also the analgesic onset in the radial and musculocutaneous nerves was significantly faster than the other two nerves ( P < 0.05 and P < 0.01). Furthermore, the intensity of motor blockade was greatly potentiated when alkalinized lidocaine solution was employed. There was no significant increase in plasma concentration of lidocaine in patients who were given alkalinized solution.

Idiopathic headaches are probably the most common problem in schoolchildren. The prevalence increases up to 70% in 14-year-old adolescents, with migraines ranging from 10% to 20%. Tension headaches are often understandable on a psychosocial and behavioral basis; in migraine, however, a familial disposition of 60%-80% is well known. ⋯ It is presently unknown, whether pharmacological prophylaxis during several months followed by attack-free periods of months or years may influence the long-term prognosis. For tension headaches, transcutaneous electrical nerve stimulation (TENS) has produced good improvement in recent investigations in about 3/4 of cases; full remissions were possible in most cases. A combination of relaxation and behavioral therapy should be recommended where possible, especially in cases of therapeutic resistance.

Devil's club (Oplopanax horridum) is a popular medicinal plant used by Native Indian tribes in the Pacific Northwest. One reported indication for using this plant is in the treatment of diabetes mellitus. ⋯ The authors performed a pilot study in which blood glucose levels were carefully monitored in an insulin-dependent diabetic patient, a newly diagnosed non-insulin-dependent diabetic, and two healthy adults while they drank devil's club tea. The limited data do not show any hypoglycemic effect of devil's club tea.

Diarrheal diseases are major causes of morbidity, with attack rates ranging from two to 12 or more illnesses per person per year in developed and developing countries. In addition, diarrheal illnesses account for an estimated 12,600 deaths each day in children in Asia, Africa, and Latin America. The causes of diarrhea include a wide array of viruses, bacteria, and parasites, many of which have been recognized only in the last decade or two. ⋯ The rational management of infectious diarrhea requires the highly selective use of laboratory tests for these varied etiologic agents, depending on the clinical and epidemiologic setting. The purpose of this review is to provide an overview of the magnitude, special settings, and etiologies of diarrhea endemic to developed and developing countries. This information permits a practical approach to the diagnosis and management of common diarrheal illnesses in different settings.
