[This article is a review of the changing indications for percutaneous coronary angioplasty during the last decade. The role of revascularisation and especially of PTCA in the treatment of coronary heart disease is explained. Coronarography is the most important morphol gic diagnostic tool for coronary artery disease. The importance of the topic of this article is enhanced by the position of Hungary at the top of morbidity and mortality statistics, and by the infrequency of revascularisation procedures, especially PTCA. PTCA proved to be a real alternative to a surgical procedure in about half of the patients indicated for revascularisation. PTCA is less invasive, requires less time for recovery and is less expensive compared to bypass surgery. This article should draw attention of the family practitioner to the importance of this method. ]

[This review discusses the principal features of ceftazidime based on the ten years experience since the introduction of the drug in the clinical practice: its broad antibacterial spectrum including Pseudomonas aeruginosa, favourable pharmacokinetics, wide range of indications, excellent clinical efficacy using empiric treatment or elective therapy and safety profile. ]

[Symptoms of ischemic heart disease will occur when myocardial perfusion diminishes below a critical level. Coronarography will disclose the anatomic stenoses, but there is no direct correlation between the grade of stenosis and the change of myocardial perfusion. Myocardial contrast echocardiography is a new technique to analyze the myocardial perfusion. The contrast agent contains micro bubbles which have nearly the same dimensions as red blood cells. The microbubbles increase the „whiteness" of the perfused myocardium during the echocardiographic examinations. The change in „whiteness" of the myocardium correlates with myocardial perfusion. Intracoronary injections delineate the perfusion area of the coronary artery, and Thus the coronary flow reserve and the collateral flow area can be measured. The cardioplegia fluid distribution and the graft perfusion area are examined intraoperatively. Bedside myocardial perfusion studies will be possible through the transpulmonary passage of intravenously injected contrast agents. Myocardial contrast echocardiography can be applied both in the diagnosis and treatment of ischemic heart disease.]

[Circulatory failure worsened to the point of discontinuation in 23 patients in the diuretic + ACE inhibitor + placebo only group, compared to only four patients in the digoxin group (p<0.001). The relative odds of worsening circulatory failure with placebo compared with digoxin was 5.9. All measured parameters of functional capacity (maximal exercise capacity, submaximal exercise capacity, NYHA grade) worsened with digoxin withdrawal. Similarly, quality of life (p=0.04), ejection fraction (p=0.001), heart rate (p<0.001) and body weight (p<0.001) decreased with digoxin instead of placebo.]

[The circulatory changes and the characteristics of blood flow in certain uterine vessels can be detected by transvaginal color Doppler in early pregnancy. The uterine circulation of 53 patients with normal intrauterine pregnancies at 4–14 weeks of gestation and 104 non pregnant patients were investigated. The main uterine artery, arcuated and spiral arteries were demonstrated by color Doppler in all patients in early pregnancy and characteristic flow velocity waveforms were obtained in 94% of the cases. The impedance to flow in the main uterine artery was significantly lower and the mean velocity was significantly higher in early pregnancy than in non pregnant patients. The indices of impedance to flow decreased with gestation in the uterine branches and there was a progressive fall in these indices from the uterine artery to the spiral arteries. Mean blood velocity in the uterine artery increased with gestation. The hemodynamical changes which are proportional to gestation age give an indirect evidence of the adequate maternal blood supply for the growing embryo.]

[Every Hungarian citizen has the right to the highest quality of health care free of charge.This was the basic tenet of the socialist health care system, which, with its hypocrisy and lies, made all reform efforts hopeless from the start. Worse still, for successive generations of doctors, unreality became the defining feature, and the only protection against its demoralising effects was the closeness of a few worthy individuals, their professionalism and human decency. ]
Clinical Neuroscience
[In Hungary the prevalence of cerebrovascular disorders has increased so that each year vascular reconstruction surgery is needed in 2800 cases. However, only a quarter of these eligible patients are operated. After a thorough examination if all the indications for carotid surgery are met, more and more patients will end up in vascular reconstruction units. Angiography and surgery are recommended if the carotid artery stenosis is asymptomatic and is more than 90%. Also, under special conditions an asymptomatic carotid stenosis may caused by indicate surgery (before coronary by-pass operation, etc.). Another indication is a transient ischemic attack, if carotid artery lesion and the stenosis is above 70%. Ulcerated plaques also need surgery because they are a likely source of emboli. After stroke surgery may be necessary if the angiologic status is unstable and further ischemic events, that may lead to disability are expected. An acute stroke rarely calls for surgery. In contrast to this, immediate surgery is needed after repeated, TIA, or crescendo TIA because the risk of stroke is very high in these cases. Finally, sometimes surgery is indicated because of the occlusion of internal and common carotid artery. With vertebrobasilar vascular reconstruction, we do not have enough experience. Cerebrovascular syndromes due to supraaortic vascular lesions are other indications for reconstruction surgery. However, surgery is never a satisfactory substitute for pharmacological treatment.]
Clinical Neuroscience
[The author provides an overview on the value of evoked potential (EP) methods (VEP, SEP, BAEP, MEP) in the diagnosis and follow-up of various neurological diseases (multiple sclerosis, cerebrovascular disorders, degenerative diseases, coma, epilepsy, migraine) by reviewing the literature supported by his own clinical experience. While in the past EP was mainly used for establishing the diagnosis, recently, with the expansion of neuroradiology, it has gained a wider use in the assessment of the severity and extent of the pathologic process and especially in longitudinal follow-up. Its role in the diagnostic phase has diminished. In patients with multiple sclerosis the abnormality of the evoked potentials correlate better with the clinical state than with the MRI results. The method is also suitable to monitor the response to therapy. The importance of the EP tests is illustrated by several case demonstrations.]

[The improvement of contact lens materials and types have made it possible to use contact lenses for visual rehabilitation besides optical and cosmetic use, The high oxygen permeability of contact lenses have extended the age limits for contact lens wear and encouraged clinicians to use them for therapeutic purposes, especially for pain relief and aiding cornea epithelialisation. Contact lenses can be worn safely for years if rules of hygiene are followed. Their use is most frequently abandoned because of contact lens related dry eye. Despite the high oxigen permeability, their prolonged wear increases the risk of inflammation.]
