[Lung cancers are the leading cause of tumorous mortality and the most frequent tumor in the 40- 70 years age range. The chance for cure in lung cancers is much higher in the early stage of disease so the early diagnosis has a paramount importance. Although many tumor markers are used in the diagnosis of malignant tumors, their specificity raise some doubts. The increased level of hCG is traditionally connected with choriocarcinomas and the CA 19-9 antigen is connected with gastrointestinal carcinomas. The production of hCG and CA19-9 is extremely rare but well established fenomenon in pulmonary carcinomas. In some cases of pulmonary cancers various tumor markers are produced, causing differential diagnostic difficulties. Through our cases and literature review we wanted to draw the attention of the organ unspecificity of these tumor markers.]

[Farewell to rosiglitazone: where to go?]

TAMÁS GYULA, KERÉNYI ZSUZSA

[The European Medicines Agency concluded that the marketing authorisation for all rosiglitazonecontaining medicines (Avandia, Avandamet, Avaglim) should be suspended across the European Union. The National Health Insurance Fund Administration in Hungary in a circular letter called the attention of GP’s to the necessity in getting the medical proposal (of an internist, endocrinologist or diabetologist) for substituting rosiglitazone to arrange a smooth modification of their treatment regimen. The review taking into account updated recommendations of the ADA-EASD and the Hungarian Diabetes Association summarises the potential drugs. The first line therapy of choice has to be starting with insulin. Pioglitazone might also be administered, with all known side effects of the glitazone family, e.g. congestive heart failure and bone fractures. Further alternatives are choosing the newer drugs of the incretin principle: the incretin mimetics (exenatid, liraglutid) and the incretin enhancers (sitagliptin, vildagliptin, saxagliptin). Beside their favourable profile of effect they do not have longterm follow up outcome studies and evidences for cardiovascular safety.]

[On rivaroxaban’s mechanism of effect]

BODA Zoltán

[A new era of anticoagulant therapy is approaching. No new oral anticoagulants have been introduced for seventy years. However, two large groups of anticoagulants (molecules with anti-FXa and anti-FIIa acitivity) are currently at advanced stages of clinical trials. This publication summarises the most important information on the mechanism of effect of the anti-FXa drug rivaroxaban. The possible advantages of the “direct” effect and the anti-FXa effect are emphasized. The most significant drug interactions of the new anticoagulant are also presented.]

[Pancreatology in practice: acute pancreatitis]

TAKÁCS Tamás

[Acute pancreatitis requires various diagnostic and treatment procedures. The clinical picture of acute pancreatitis is diverse, ranging from mild abdominal pain or dyspepsia to severe, lifethreatening multiorgan failure or sepsis. Most cases of pancreatitis result in a mild/edematous inflammation of the pancreas, whereas the remaining 15-20 percent results in severe necrotising pancreatitis with a mortality rate as high as 10-30 percent, although imaging diagnostics, operative endoscopy and intensive internal and surgical therapy have improved significantly in the past few years. Quick and accurate diagnosis of the disease is required for early therapeutic intervention. For example, we know that in cases of biliary acute pancreatitis an early (within 24-48 hours following the onset of symptoms) endoscopic sphincterotomy and stone extraction significantly improve the prognosis of the disaese. It is also important to introduce an adequate perfusion/rehydration therapy and a simultaneous enteral feeding introduced as soon as possible to avoid the superinfection of the pancreatic necrosis. Therefore, when reviewing the epidemiological characteristics, pathophysiology, up-to-date diagnostic and therapeutic approaches of the disease, we emphasise early interventions. We also highlight the importance of patient care and follow-up checks after an incident of acute pancreatitis.]

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

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.

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

Matrix metalloproteinases (MMPs), which are synthesized by many cell groups and responsible for the destruction of matrix proteins, and endogen tissue inhibitors of MMPs (TIMPs) have a role in the pathogenesis of Multiple Sclerosis (MS) by affecting the blood-brain barrier. We aimed to investigate the role of MMPs and TIMPs in the immunopathogenesis and in the course of multiple sclerosis (MS). We enrolled 25 relapsing remitting MS patients, who had a definite MS diagnosis according to McDonald criteria and 25 healthy subjects similar for age and gender as control group. MMP-9- and TIMP-1 levels were measured twice in patient group (one time during an attack and one in remission) and once in healthy subjects. MMP-9- and TIMP-levels of patients during attack and remission period and MMP-9/TIMP-1 ratio were found significantly higher than in the control subjects. In patient group MMP-9 and TIMP-1 levels and MMP-9/TIMP-1 ratio during attacks were not significantly different than during remission period. However, when subdivided according to their number of attacks, patients with 2 attacks had significantly higher levels during attack period comparing to remission period (p<0.05); in case of patients with more than 2 attacks did not have a statistically significant difference in attack and remission periods. Matrix metalloproteinases are important actors in MS immunopathogenesis, particularly in the early period and inhibitor agents for these enzymes can be used as a treatment option.

[Rehabilitation possibilities and results after neurosurgical intervention of brain tumors ]

DÉNES Zoltán, TARJÁNYI Szilvia, NAGY Helga

[Objectives - Authors examined the rehabilitation possi­bi­lities, necessities, and results of patients after operation with brain tumor, and report their experiences. Method - Retrospective, descriptive study at the Brain Injury Rehabilitation Unit, in National Institute for Medical Rehabilitation. Patients - Patients were admitted consecutively after rehabilitation consultation, from different hospitals, following surgical intervention of brain tumors, between 01 January 2001 and 31 December 2016. Patients participated in a postacute inpatient rehabilitation program, in multidisciplinary team-work, leaded by Physical and Rehabilitation Medicine specialist included the following activities: rehabilitation nursing, physical, occupational, speech, psychological and neuropsychological therapy. Results - At the rehabilitation unit, in the sixteen-year period 84 patients were treated after operation with brain tumor. Patients arrived at the unit after an average of 41 days to the time of the surgical intervention (range: 10-139 days), and the mean length of rehabilitation stay was 49 days (range: 2-193 days). The mean age of patients was 58 years (20-91), who were 34 men and 50 women. The main symptoms were hemiparesis (64), cognitive problems (26), dysphagia (23), aphasia (16), ataxia (15), tetraparesis (5), and paraparesis (1). The mean Barthel Index at the time of admission was 35 points, whereas this value was 75 points at discharge. After the inpatient rehabilitation, 73 patients improved functionally, the status of 9 patients did not show clinically relevant changes, and 2 patients deteriorated. During the rehabilitation 10 patients required urgent interhospital transfer to brain surgery units, 9 patients continued their oncological treatment, two patients continued rehabilitation treatment at another rehabilitation unit, and after rehabilitation 73 patients were discharged to their homes. Conclusions - Inpatient rehabilitation treatment could be necessary after operation of patients with brain tumor especially when functional disorders (disability) are present. Consultation is obligatory among the neurosurgeon, rehabilitation physician and the patient to set realistic rehabilitation goals and determine place and method of rehabilitation treatment, but even at malignancies cooperation with oncological specialist also needed. Authors’ experience shows benefits of multidisciplinary rehabilitation for patients after brain tumor surgery. ]
