[Bacteriophage therapy and prophylaxis; Renewal of earlier expectations]

MILCH Hedda

[Bacteriophages were discovered 84 years ago by the observation of a lysis of a bacterial culture. The aim of the earliest attempts was the therapeutic employment of bacteriophages. The experiments controlled unsatisfactorily, could not fulfill expecations and successful antibiotic testing resulted the rejection of bacteriophage therapy. Bacteriophages gained importance in biology in the 1950s, as model viruses in biological and genetic research. The decrease in the success of antibiotic therapy caused to renew efforts in experimental phage therapy. The author reviews the early studies carried out mainly on animals as well as human experiments with bacteriophages purified by genetic methods. According to the results, bacteriophage therapy may be effective under certain circumstances for the infections not treatable by antibiotics, and in the case of antiobiotic-susceptible bacteria it can supplement therapy.]

[Newly discovered molecules the chemokines]

KŐHIDAI László, DÉRFALVY Beáta

[Chemokine research in the last decade has provided new results in several areas of biomedicine. Investigation and characterization of chemokines resulted in better understanding and modeling complex pathophysiological and immunological processes. Chemokine research opened up entirely new aspects on the defense against pathogenic agents as well as on the processes of inflammation and angiogenesis. With the amount of clinical data growing steadily, it is clear that chemokines could play very important role not only in solving the problems of the oretical and experimental biology but also with their application in clinical diagnostics and therapy. ]

[Effect of calcium channel blocking drugs on the periodontal status of hospitalised patients]

KEGLEVICH Tibor, ZSIDRÓ Emese, BENEDEK Erika, BARNA István, SZEGEDI Zsolt, SCHWAB E. Richárd, GERA István

[Ca2+-channel blockers play crucial role in the chronic treatment of hypertension and cardiac arrhythmia. One of the side effects of the chronic nifedipine treatment is gingival enlargement. The pathomechanism of this side effect is not fully understood. The main objective of the present study was to evaluate the potential role of different factors in the development and severity of gingival hyperplasia. The incidence and severity of gingival enlargement were examined around the six surfaces of all fully erupted teeth in 243 hospitalized patients with the modified Angelopoulus-Goaz Gingival Hyperplasia Index. 172 patients in the study group were on Ca2+ channel blockers for at least three months prior to the examination while 71 inpatients served as controls. Gingival hyperplasia occurred in 87% of the test group and in 53% of the control group. Severe gingival enlargement occurred in 35% in the test group and only in 2% of the control group. The age and gender of the patient, the daily dose of the medication, the duration of the administration of the drug showed no correlation with the extent and severity of gingival hyperplasia. Only oral hygiene showed statistically significant correlation with the severity of gingival enlargement. The only clinical parameter influencing the extent and severity of gingival enlargement associated with Ca2+-channel blocker drugs was the quality of oral hygiene. ]

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

[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. ]
