The effect of chlorophenothane (pp'--DDT) and five structurally related compounds op-DDD (op'-DDD, pp'-DDD, DTE, DCMP and DCP see text) on the cerebral hemisphere gamma-aminobutyric acid (GABA), the main inhibitory transmitter in brain contents and possible correlation with central activities was demonstrated in rats. The tested compounds were given in oral doses of 600 mg/kg in peanut oil. Cerebral GABA content was determined 1, 3 and 6 hrs after the ingestion of pp'-DDT and 3 hrs after each of the other drugs. The mean GABA content in each group of rats was compared with control groups, either without any treatment, or receiving the equivalent volume of peanut oil. pp'-DDT produced a significant reduction in brain GABA contents 3 and 6 hrs after its administration. This was accompanied by excitability, tremor and clonic convulsions. Of the congenors, only DTE exerted a similar effect. The present results point to the possibility of partial involvement of GABA in the tremor and convulsions induced by pp'-DDT. They also indicate the importance of the CCl2 grouping in the molecule for the induction of central effects of pp'-DDT.

Two years of prescriptions for all the drugs included in the Italian National Formulary by 3,866 general practitioners, in a region of Northern Italy of almost 4 million inhabitants, were analysed to determine the pattern of drug use. The data (official code and proprietary name of the drug, number of packages prescribed, price of the drug, dispensing pharmacy, and date of dispensing) were collected monthly by retail pharmacies and were recorded and organized in database files. Quantitative and qualitative profiles of prescription patterns were studied for all the major therapeutic areas. Overall drug prescriptions averaged 600 DDD/1,000 inhabitants/day. Comparison of 1988 and 1989 data showed only a slight increase in total drug prescriptions, but greater changes were detected in certain drug groups, especially those recently marketed. Overprescription of well-documented drugs, such as H2-antagonists, ACE-inhibitors, calcium antagonists and the HMG-CoA-reductase inhibitors, in comparison to other countries was shown. There was frequent prescribing of drugs devoid of documentation of their clinical efficacy, which were mainly given for clinical conditions lacking a specific treatment, or as placebos for minor disorders. The data demonstrate the need for educational intervention to improve the quality of drug prescribing habits in primary health care in Italy.

In patients undergoing permanent cardiac pacing, the maintenance of atrial contractility is important to ensure adequate ventricular filling and to guarantee an optimal ventricular ejection capacity. The appropriate pacing mode, assuring a suitable mechanical atrioventricular coupling, prevents the onset of atrial fibrillation and contributes to reduction of the risk of subsequent systemic and pulmonary thromboembolic episodes. We examined 461 patients (266 males and 195 females, aged between 52 and 97 years, average age 76.5 +/- 18) paced for conduction disturbances of various degrees and etiology. Of them, 323 patients received ventricular demand pacemaker (VVI group, average age 77.9 years); 138 underwent dual chamber pacing (DCP group, average age 75.2 years), 117 of the latter received universal demand pacing (DDD) and 21 atrial synchronous ventricular demand pacing (VDD). The patients were subsequently divided into two age-groups: Group A (</= 75 years, 174 patients), and Group B (>/= 75 years, 287 patients). According to pacing mode and successive development of stable atrial fibrillation (AF), we analysed the occurrence of systemic and/or pulmonary thromboembolic episodes and the incidence of fatal events. During our study, performed from January 1986 to August 1993, 70 embolic episodes were observed in the VVI group and six in the DCP group. Eighty-four patients with VVI units developed AF during follow-up, compared with only five patients in the DCP group. Our data indicate that VVI patients have a higher incidence of AF, embolic complications and cerebrovascular mortality, in comparison with the DCP group. VVI pacing should be avoided, especially in older patients, when atrial rhythmical activity is present.

Hypertension is chronic disease with high prevalence, which can successfully be treated with antihypertensive drugs. Previous researches have shown that existing hypertension treatment guidelines are not fully implemented in practice. We have analysed antihypertensive drug utilization in Canton Sarajevo during five-year period (2004-2008). Research findings are discussed in relation to expected drug utilization according to Canton Sarajevo treatment guidelines. Objective of this research is to examine prescription patterns of antihypertensive drugs in primary health care in Canton Sarajevo during five-year period. Based on study findings we did an estimation of adherence to local treatment guidelines, which are similar to those published globally. Drug utilization data were collected from the largest pharmacy (retail) chain, representing more than 80% of pharmacies in Canton Sarajevo. Following drug groups have been analyzed: diuretics, beta-blockers, calcium-channel-blockers, ACE-Inhibitors (plain and combinations), Angiotensin-II-antagonists and alpha-blockers. Drug utilization is expressed in number of defined daily dose (DDDs), defined daily dose per thousand inhabitants per day (DDD/TID), drug utilization 90% (DU90%) and value in euros. ACE-Inhibitors are most prescribed drug class; combination of ACE-Inhibitors and diuretics account 46% of total antihypertensive budget spending. ACEIs are followed by calcium-channel-blockers. Diuretics utilization is decreasing from 2006 and being replaced with beta-blockers. Diuretics, recommended as first line therapy, are ranked as third in total antihypertensive drug utilization. It is necessary to introduce follow-up and enforce adherence to developed treatment guideline. Drug utilization studies can be used as tool for assessment of treatment guidelines adherence in primary health care.
