Lege Artis Medicinae - 1992;2(05)

[Several antiarrhythmics can alter pacing thresholds. Especially, the Class 1 C drugs may increase the threshold. Corticosteroids and sympathomimetic agents lower the threshold. Some drugs must be avoided in pacemaker dependent patients. The potential pacemaker-drug interaction must always be considered when prescribing a new drug. Significant clinical sensing problems have not been recognized with antiarrhythmic drugs. The sensor function of rate responsive pacemakers can be altered by concomitant drug therapy. ]

[Treatment of endodermal thyroid cancers]

ÉSIK Olga, NÉMETH György

[Following staging procedures, differentiated thyroid cancers i. e. papillary and follicular carcinomas, are surgically treated with intra- or extracapsular total thyroidectomy (depending on the anatomical extent of the disease) and selective lymphnode dissection. Postoperative complementary use of adjuvant external and systemic radiotherapy is the general practice. External irradiation decreases local/regional relapses in all cases. Radioiodine treatment decreases local/regional/ distant recurrences in cases of tumour cells capable of iodine uptake. Life-long thyroxine medication is required, with a TSH-suppressive dose for relapse prevention and hormone substitution. This treatment regimen, a careful follow-up, and adequate rescue therapy are the prerequisites of the generally excellent patient prognosis, i. e. a survival probability measurable in decades. In anaplastic carcinoma following extracapsular total thyroidectomy and lymph node dissection, external irradiation is always indicated. Chemotherapy has a benefical effect on survival. Hormone replacement therapy is necessary to substitute for the missing metabolic effect of the thyroid. This combined modality treatment leads to some improvement with regard to the prognosis of this poor-risk type of cancer. ]

["Programmed cell death" I read with great interest and attention Dr. Béla Szende's excellent communication on the biological and pathological significance of programmed cell death (apoptosis). Although the phenomenon of apoptosis (albeit under a different name) has been described for more than twenty years, its importance in the regulation of tissue homeostasis has only been recognized in the last few years. In 1991, for example, Jean Claude Ameisen and Andre Carpon of the Pasteur Institute in Lille put forward their hypothesis that apoptosis explains the qualitative and quantitative deficiency of helper T cells in HIV-infected patients.]

[Malnutrition syndrome in childhood part II.]

BAKSAI László, PHILIP W. H. Esker

[Malnutrition is a chronic nutritional disorder resulting from insufficient intake of caloric energy and/or some fundamental nutrients. Since it is the most common public health problem in the world it has a great impact on pediatric morbidity and mortality. The etiology is extremely complex. When one considers the less severe symptoms and signs caused by vitamin-, mineral-, and trace element deficiencies, it is apparent that not only children living in underprivileged countries are affected. In the course of making the diagnosis an assess ment of the nutritional status should also be made, especially considering the above-mentioned marginal nutritional deficiencies. The most common manifestation of nutritional disorders is anemia, which is mostly caused by lack of iron, vitamin B12, folic acid and can be complicated by infections. Nutritional requirements can be affected by several drugs. That is why this medication-nutrition interaction has to be kept in mind during treatment. The interaction of malnutrition and infection is very important, primarily for three reasons: mechanisms by which infection complicates the metabolic and nutritional status of the host; importance of suboptimal nutritional status on susceptibility and severity of intercurrent infections; clinical and therapeutic implication of these interactions. ]

[Operative Hysteroscopy]


[Many thousands of hysterectomies are perfor med each year in women suffering from menorrhagia resistant to medical treatment but having, no demonstrable uterine abnormality. Hysteroscopy, the up to date diagnostic and therapeutic method can help to get advance in the diagnosis and therapy in these situations. In addition to permitting more precise diagnoses to be made, hysteroscopy allows the endometrium to be treated selectively under direct vision. The full thickness of the endometrium may be ablated using laser or resectoscope. The benefits of selective endometrial destruction versus hysterectomy are enormous. Patients undergoing endometrial ablation are frequently delighted with the short hospital stay, and the cost of this procedure is lower than the cost of hysterectomy. Many Müllerian fusion defects are amenable to hysteroscopic treatment. Patients with certain types of Müllerian defects undergoing hysteroscopic septotomy will enjoy as high a rate of reproductive success as those receiving more traditional procedures while avoiding the risks, the subsequent caesar sections, and the high cost. ]

[Transvaginal ultrasonography of embryo development in prematurity, sono-embryology I. The embryo and its appendages]

CSABAY László, SZABÓ István, NÉMETH János, PAPP Zoltán

[The authors performed serial examinations by a high resolution transvaginal transducer during the first trimester of pregnancy to show the most important stages of the early embryonal development. This is a preliminary study to a prospective, detailed screening programme in the first trimester of pregnancy. The earliest sign of pregnancy can be detected at the 29–31st days of menstrual age using vaginal transducer. During the 5th week the (secondary) yolk sac can be seen, which is an unambiguous evidence of an intrauterine pregnancy. The living embryo can be de monstrated on 36–38th days with the help of the pulsation of the embryonic heart tube. Certain embryonic structures appear in a defined order (developmental „calendar"). The physiologic midgutherniation can be observed during 7–11th weeks. Transvaginal sonography has gained popularity only recently due to technical advances. The main fields of use became gynaecology and early pregnancy, for there is no need to have a full bladder, for the lack of disturbing tissue layers. This method is essentially a combination of the bimanual gynaecological and the ultrasound examination. ]

[The treatment of life-threathening ventricular tachyarrhythmias in coronary artery disease - Antiarrhythmic drug or implantable cardioverter-defibrillator?]


[Sudden cardiac death due to sustained ventricular tachyarrhythmias accounts for approximately 50% of all cardiovascular deaths. From the major therapeutic options currently available, antiarrhythmic drug therapy and implantation of automatic car dioverter-defibrillators could be applied to the great majority of patients. Both early observations on automatic implantable cardioverter-defibrillator devices and more recent prospective, randomized, multicenter trials with long-term outcome data uniformly document sudden cardiac death recurrence rates of 1% to 2% annually, compared with recurrences rates of 15% to 25% without the device. There is now compelling evidence from studies suggesing that these devices are superior to antiarrhythmic drugs (Class I and III), both in terms of effectivity and life-saving effects. The implantation of the automatic cardioverter-defibrillator device is currently the first choice therapy for cardiac arrest survivors based on the AHA/ACC guideline (1998), and has to be considered in each case. In the future, the common, hybride treatment with antiarrhythmic device and drugs is expected. ]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]


[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]
