[Metamizole in use for almost 100 years, is reviving in our days since it has proved its efficiency and gained popularity during the past years. By its special triple effect (analgesic, antipyretic and spasmolytic) it has a wide range of indications. Among the non-opioid analgesics it is one of the most powerful painkillers. Metamizole is a prodrug, since it transforms into active metabolites within the human body. Its action mechanism is complex, not completely understood so far. Contrasted to classic non-steroidal anti-inflammatory drugs, metamizole has low anti-inflammatory effect. Its severe, but very rare side effect – i.e. the agranulocytosis - hindered its administration for years and even today it is under intense discussions. Based on international studies, it proved to be a well tolerable, safe medication. Its side effect profile differs from non-steroidal anti-inflammatory drugs, thus in NSAID contraindications it provides an excellent alternative. Its good water solubility makes metamizole suitable for both oral and parenteral administration. For its efficiency and good safety profile, metamizole has been correctly reintroduced to the supply of over-the-counter painkillers in our country.]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]

FARSANG Csaba

[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.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

[30 year history of surgery and the surgeon’s future ]

KUPCSULIK Péter

[During the past 3 decades, laparoscopic surgery has launched a revolution in operative medicine. The German gynaecologist Kurt Semm transformed the diagnostic laparoscopy for therapeutic procedure, as he performed the first laparoscopic ap­pen­dectomy. The surgeon Erich Mühe contributed with laparoscopic cholecystectomy to the set of surgical instruments. All over the world, a wide spectrum of laparoscopic procedures has been app­lied. Several laparoscopic procedures are now preferred over open approaches. Morbid obesity is associated with significant comorbidity and mortality. In­suffi­ciency of dietary measures lead to development of surgical interventions that resulted in unexpected excellent outcomes. “Metabolic surgery” was born. New methods and rising market of socio-medical requirements inspired progress in plastic surgery. Thanks to innovations in technology, reconstructive breast surgery has opened new ways. In the 1990s the prototype of “mas­ter–slave” robot controlled by a surgeon was constructed. Future of robotic surgery depends on cost reduc­tion, development of new technologies and creating the best applications. Coo­pe­ra­tion with partner medical specialities is essential for further development in surgery. Despite of obvious impact of new technologies the surgeon's way of thinking, personal qualities decision-making and professional knowledge remain cru­cial for further evolution. ]

[Pain sensitivity changes in schizophrenic patients and animal models - Part II.]

TUBOLY Gábor, HORVÁTH Györgyi

[Diminished pain sensitivity in schizophrenic patients has been reported for more than 50 years, however little is known about the substrate and the basic mechanisms underlying altered pain sensitivity in this disease, therefore, relevant animal models are of decisive importance in the study of psychiatric diseases. The authors report a review consisting of two parts focusing on pain sensitivity changes in patients and in different animal models which proved the eligibility as schizophrenia models and pain sensitivities have also been determined. The second part of this article analyzed the results regarding knock out mice as schizophrenia models. These data proved that several genes have significant role in the pathomechanism of schizophrenia; therefore deficiency in one gene does not produce animals showing all signs of this disease. As regards the pain sensitivity changes, only a few data are available with controversial results. Data originated from complex chronic animal models indicate that they might be more adequate methods for studying the mechanisms of schizophrenia including the pain-sensitivity changes.]

[Pain relief in metastatic bone disease]

BOÉR Katalin

[Metastatic bone disease is a hallmark of distant relapse of a number of solid tumours. The treatment of bone metastases is palliative, the main goal is to relieve pain, whereas it’s also important to reduce the risk of bone fractures, prolong survival and maintain the physical activity of patients. Pain is one of the most common symptoms of bone metastases, and state-of-the-art pain relief has an important role in maintaining the patients’ quality of life. Therapies to control pain include drug therapy, radiotherapy, surgery, systemic oncotherapy, such as chemotherapy and/or hormone therapy, multibone radioisotope therapy and administration of bisphosphonates. Regarding the relief of pain caused by malignant tumours, the guidelines developed by the World Health Organization should be followed. The algorithm of pain relief starts with assessment of the pain’s intensity and includes both pharmacological and nonpharmacological interventions. Analgesics used for pain relief include nonopioids, opioids and adjuvant agents. The pain can be efficiently relieved with the combined use of modern analgesics in the great majority of patients.]

[Pain management in rheumatology]

NAGY Katalin

[Pain is the most common symptom in rheumatology, which can be of mechanical or inflammatory origin, acute and chronic, nociceptive, neuropathic and psychogenic. Pain can be relieved by analgesics, nonsteroidal anti-inflammatory drugs, opioids, adjuvants and special drugs depending on the etiology, for example a gout attack can be stopped by colchicine. For pain relief, we use therapeutic guidelines of the World Health Organization (WHO), which recommends the use of analgesics, NSAIDs and adjuvants as the first step, weaker opioids as the second, and strong opioids as the third step. In rheumatology, the first step's drugs are generally used. If possible, NSAIDs should be administered briefly, potentially combined with analgesics and muscle relaxants. If pain management is insufficient, tramadol should be given. Pain relief in rheumatology also include the use of local and intraarticular injections, physiotherapy, TENS and balneotherapy. Complex therapies that combine the above mentioned methods is often more effective than the use of medications only.]

[The pain-trigger role of cytokines in the nervous system – the direct analgesic effect of anti-cytokine therapy ]

HODINKA László, VERECKEI Edit

[Nociceptive, neuropathic and central me­chanisms are involved in the perception, transmission and processing of chronic pain and shaping of cerebral pain image. Alar­mins – molecules alarming defence and signing the presence of pathogens and tissue damage - trigger a series of pathogenic events resulting in inflammatory pain stimuli. Proinflammatory cytokines play a determining role in the pain perception at the level of the nervous system. Continuous inflammatory stimuli while sensitizing the periferic and central neurons activate the pain-related cerebral areas and develop the complex pain image, the pain matrix. Ce­reb­ral functional connections are operating in networks and can be visualized by functional MRI. Cytokines activate the neurons directly or indirectly by other neuromediators. Cytokine receptors are expressed on no­ciceptors and even on higher-level neurons and on various non-neural cells, such as microglia and astrocytes. The most ubiquitous cytokines are the Tumour Necrosis Factor and Interleukin 6 in the nervous sys­tem. The signaling pathways are the Nuclear Factor κB and the Janus-kinase enzyme system. The proinflammatory cytokines and the Janus-kinase are therefore primary therapeutic targets. Anti-cytokine biologicals and small molecular kinase inhibitors decrease the pain and improve functional activity in rheumatoid arthritis. Decrease of pain was more pronounced than expected only from the decrease of the clinical biomarkers of inflammation. The early and ra­pid painkiller effect of targeted biological and chemical-biological response modifiers is attributed to their direct analgesic effect on the brain.]

[Pain and opportunities for non-pharmacological pain management in intensive neonatological care]

ANDREK Andrea

[Neonatal intensive care and therapeutic process is accompanied with a range of painful interventions. Research data from the past decades revealed that repeated and/or prolonged pain has long-term consequences on the neurobiological development of the premature infant, which has led to an increased attention to the measurement and alleviation of pain. In addition to pharmacological pain relief, more and more alternative pain management methods of varying efficacy are appearing in the provision of care for premature infants. In this study, we introduce non-pharmacological pain treatment methods with proven efficiency that can be applied to complement the pharmacological pain management or as a therapy before any painful interventions in intensive neonatological care. These methods include heart sound and music therapy, nutritive and non-nutritive sucking, swaddling, touching and kangaroo care.]
