Initial experience of clinical pharmacology and clinical pharmacy interactions in a clinical pharmacokinetics consultation service

International statistics indicate that there is a close correlation between the consumption of saturated fats (dairy fats and meat fats) and the mortality from coronary heart disease (CHD), and this conception has been confirmed by many epidemiological studies. Such studies alone, however, cannot prove the existence of a cause-and-effect relationship between these two variables; dietary intervention trials are needed. The Finnish Mental Hospital Study was such a trial, conducted in two hospitals near Helsinki in 1959--1971. Practically total replacement of dairy fats by vegetable oils in the diets of these hospitals was followed by a substantial reduction in the mortality of men from CHD. Total mortality also appeared to be reduced. As to the causes of death other than CHD, none was significantly influenced by dietary change. This was also true for malignant neoplasms. To alleviate the burden of CHD on public health, many investigators have recommended important changes in the quantity and quality of dietary fats.     

The fluoride content of teeth in the canton of Vaud 5 years after the introduction of salt fluoridation

Fluroide concentrations in teeth from the canton of Vaud were about at the same level reported from regions with 1,0 ppm F in the drinking water and from children receiving fluoride tablets during tooth formation age.     

Early diagnosis of rheumatoid arthritis

On the basis of own observations of courses the author adopts a definite attitude to the early symptomatology of the rheumatoid arthritis. During the first weeks of the rheumatoid arthritis the following symptoms are found: articular syndromes, more frequently in form of obstinate polyarthralgias, mono-oligoarthritis, accompanied by morning rigidity and accelerated BSR as well as impairment of the general condition. In the majority of the patients only the tentative diagnosis rheumatoid arthritis may be made. After a one to three months' course of the disease the diagnosis becomes more probable. It is above all based on constancy and symmetry, characteristic localisation of the articular process, morning rigidity, radiologically paraarticular loosening of the structure and morphological symptoms of an acute and subacute synovialitis. 6 to 12 months after the beginning of the disease a clinical picture forms which allows to make the diagnosis of a certain or classical rheumatoid arthritis in accordance with the criteria of the ARA. The occurrence of a high activity of multiple affection of the joints (permanent symmetrical polyarthritis including the small joints of the hands and feet), distinctive morning rigidity, high fever and much accelerated BSR, beginning with the first weeks of the disease, speaks for the possibility of the development of an arthrovisceral form of the course of rheumatoid arthritis.     

Biochemical markers of strophanthin arrhythmia

The increase of the concentration of fatty acids, the reduction in the concentration of serotonin, the lowering of the activity of glucose-6-phosphate dehydrogenase and transketolase, and the development of compensated metabolic acidosis were discovered in the stage that preceded strophanthine arrhythmia. These characteristics may be recommended for a wider use on the clinical basis for predicting arrhythmias in the treatment of cardiac glycosides.     

Significance of adrenal hormones in brain energy metabolism

Intensity of glycolysis was studied under conditions of immobilization stress and adrenalectomy as well as with administration of adrenaline and hydrocortisone. The processes of aerobic glycolysis, activity of enzymes of the tricarboxylic acid cycle and mitochondria respiratory chain, content of total, free and protein-bound glycogen, glucose-I-phosphate, glucose-6-phosphate, pyruvate, alpha-ketoglutarate, cytrate and macroergs in the brain are shown to depend on the level of adrenal hormones producing a multilateral effect on a series of energy metabolism links.     

Infertility update: use of assisted reproductive technology

OBJECTIVE: To describe assisted reproductive technology (ART) and use of medications during these procedures. DATA SOURCES: Recent clinical literature. STUDY SELECTION: Not applicable. DATA EXTRACTION: Not applicable. DATA SYNTHESIS: ARTs are procedures used in treatment of infertility that involve removal of oocytes and their manipulation outside the woman's uterus. The simplest form of ART, in vitro fertilization, involves aspirating eggs from the ovaries, fertilizing them outside the body, and transferring the embryos into the uterus at the four- to eight-cell stage. Experimental regimens for in vitro fertilization include use of various medications (gonadotropin-releasing hormone agonists, human menotropins, follicle-stimulating hormone, growth hormone) at varying points in the menstrual cycle and after introduction of the embryo into the uterus. Human chorionic gonadotropin has been used to increase implantation of embryos during the woman's luteal phase. Gamete intrafallopian transfer (GIFT) involves transfer of oocytes and sperm into the fallopian tubes, where fertilization takes place. This technique has the advantage of causing the zygote to enter the uterus at the time it would during natural conception. Zygote intrafallopian transfer is similar to GIFT, except that fertilization occurs in vitro, with embryos placed in the fallopian tubes at the two-cell stage. Various micromanipulation techniques and innovative sperm aspiration procedures are currently under development. CONCLUSION: Many advancements have been made in ART, and pharmacists who understand these procedures can serve patients by providing medication information in an empathetic and supportive manner.
