[The first 15 years of the AIDS epidemic ]

FÖLDES István

[AIDS represents the most exciting infectious disease of the last 15 years. In addition to the fact that there are more than 4 million estimated AIDS patients and more than 16 million estimated HIV-infected individuals this can be explained by the peculiar features of the disease, including limited routes of infection, long latency period, a quasi 100% lethality, diversity of the clinical picture, difficulties in therapy and vaccination, the theoretically 100% possibility of prevention and the serious social problems associated with AIDS. After giving a short review of the development of our knowledge about AIDS, the author to explains the special features of AIDS mentioned above on the basis of the structure, regulation and replication cycle of the virus. The primary conclusion is that education and prevention should be stressed in the battle against AIDS.]

[The role of transesophageal echocardiography in the investigation of stroke]

LENGYEL Mária

[Ischaemic infarction accounts for 85% of stroke aetiology (1). Approximately 60-70% of these are of cerebrovascular, i.e. carotid arteriosclerosis, origin (2). The proportion of cardiogenic embolism was previously estimated at 15% (1), but autopsy data suggest that embolism is the cause of half of fatal strokes (3). There are two reasons for this large discrepancy: 1) the intracardiac source is difficult to identify in vivo; 2) cardiogenic embolism has a more severe outcome than stroke of other origin. Probably both are true, but there is no doubt that before the introduction of transesophageal echocardiography (TE), the detection of intracardiac sources was rare and uncertain.]

[A multicentre, randomised, crossover, double-necked trial of contamination of conventional and bow-tie dressings in routine obstetric and gynaecological practice]

MARINKO M Biljan, CHARLES A Hart, DEBORAH Sunderland, PAUL R Manasse, CHARLES R Kingsland

[In the 19th century, the usual dress of doctors was a small bow tie tied in a flat knot "once round" in addition to a stiff standing collar (1). As fashions have changed, the wearing of bow ties has become less common and is now worn almost exclusively by a small minority of obstetricians, who often claim that they are more hygienic than the traditional tie in the delivery room, which is contaminated with blood and amniotic fluid. There is currently no evidence for this. We therefore examined the contamination of traditional and bow ties worn by obstetricians during a typical working week. ]

[Clinical and laboratory parameters in ulcerative colitis]

NAGY Ferenc, PAPÓS Miklós, CSERNAY László

[The clinical and laboratory parameters which correlate with the intensity of the inflammatory process in ulcerative colitis patients were analyzed in this study. The severity of the inflammatory process was assessed with leukocytescinti graphy by colorectal segments using a scoring method in 36 patients (group A). The sum of the segmental scores were considered to represent the intensity of the inflammatory process and were compared with clinical and laboratory parameters. From among the 36 patients, acute ulcerative colitis was established with biopsy in 30 cases. Two toxic patients were not tested and four patients had inactive disease. In 20 (16 acute, 4 inactive) of 36 patients, the intensity of the inflammatory process was assessed by segments with score values of biopsy samples and leukocyte scintigraphy (group B). The sum of the score values was used to determine the correlation of the two methods. The intensity of the inflammatory process assessed by scintigraphy showed a good correlation (r = 0.6564, p = 0.0016) with histological findings (group B), as well as with the ESR (r = 0.6398), serum fibrinogen (r = 0.5424), alfa2 globulin level (r = 0.4721), number of bloody stools (r = 0.4605), and the thrombocyte count (r = 0,4594) in group A. Five clinical and laboratory parameters proved to be suitable to assess the actual severity of the inflammatory process in ulcerative colitis. The values of the parameters may help to choose the right examination in new cases and to evaluate the efficacy of the therapy. ]

[Prenatal diagnosis of endocardial fibroelastosis]

KÁDÁR Krisztina, KIRÁLY László

[The authors report two cases of prenatally diagnosed endocardial fibroelastosis with echocardiography for the first time in Hungary. This disease is rare and usually fatal. Diagnoses were confirmed by autopsy and in one case by postnatal echocardiography as well. Principles for the diagnosis of endocardial fibroelastosis are discussed. Echocardiography makes possible the prenatal diagnosis of endocardial fibroelastosis and is recommended from the 18th week of pregnancy in high risk individuals.]

Fluoxetine use is associated with improved survival of patients with COVID-19 pneumonia: A retrospective case-control study

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.

[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.]

[Diagnosis and treatment of microvascular coronary heart disease. Specialities of conditions in Hungary]

SZAUDER Ipoly

[Invasive investigations show that in two-thirds of patients the myocardial ischaemia persists without obstructive coronary disease and any other heart conditions (INOCA). The underlying cause may be microvascular dysfunction (CMD) with consecutive microvascular coronary disease (MVD) and microvascular or epicardial vasospastic angina (MVA). The modern practice of clinical cardiology while using the developed non-invasive cardiac imaging permits exact measuring of the coronary flow with its characteristic indices. All of these improve the diagnosing of CMD-induced myocardial ischemia and provide opportunity to determine primary MVD cases. Since the recognition and treatment of MVD is significantly underrep­resented in the Hungarian medical care, the primary stable microvascular angina (MVA) is described in detail below with its modern invasive and non-invasive differential diagnosis and treatment, concerning especially its frequency provoked by high blood pressure and female coronary heart diseases. There are highlighted all recommended diagnostic procedures available under domestic conditions.]
