[Radiological diagnostics in bone metastases]

GŐDÉNY Mária, BODOKY György

[Imaging plays a crucial role in defining bone metastases, and thus, therapy planning. We are responsible for accurate data collection, pre-treatment evaluation, evaluation of therapy response and post-treatment evaluation. Precision highly depends on the expertise and experience of the evaluating radiologist, and therefore, being familiar with the latest literature is essential. The bone status can be detected well by bone scan, analysed by conventional X-ray examination and by the cross sectional digital imaging modalities. The whole body PET/CT functional imaging is becoming increasingly popular in the metastatic workup of patients and for monitoring response to therapy. MRI has been found to be the most accurate method for bone metastasis in most comparative evaluations in the literature. This article is a review of the latest papers focusing on the clinical significance of the imaging results in bone metastasis diagnostics.]

[Rheumatoid arthritis: significance and methodology of cervical spine X-rays in everyday practice]

NÉMETH Ildikó, BUDAY Ilona, MOLNÁR Éva, NYITRAI Márta, SAÁRY Krisztina, TARKOVÁCS Andrea, VARSÁNYI Nóra, FARBAKY Zsófia

[Cervical spine joint destruction in rheumatoid arthritis may lead to progressive vertebral instability. It is a severe risk factor for cord compression, which may even lead to sudden death. Many patients with atlantoaxial subluxation may have no symptoms referable to the neck. True degree of subluxation may occur during anaesthesia when the neck muscles are relaxed and protective spasm is absent. The cervical deformities can be visualised on conventional, transoral and functional lateral view in the flexion and extension positions of the neck. The aim of our study is to demonstrate the usefulness of cervical dynamic X-ray for patients suffering from rheumatoid arthritis. This is the first classical radiological imaging method in the diagnosis and in radiographic follow-up. It is a very important method in the preoperative evaluation to prevent definitive neurologic injury. We describe the method for screening, measuring and grading cervical subluxations and instability in our everyday routine.]

[Role of radiofrequency ablation in the treatment of malignant liver tumors - Possibilities and limitations]

BÁNSÁGHI Zoltán

[Radiofrequency tumour therapy is a minimally invasive procedure. It has been used in several specialities independently of the type and location of the tumour, and has shown its worth. In primary hepatic malignancies, radiofrequency ablation (RFA) is a curative procedure. Recent publications reveal that hepatocellular carcinomas which were of cirrhotic origin and not larger than 5 cm have shown similar responses to both RFA and surgery. In cases of metastatic hepatic tumours, RFA showed slightly poorer results as compared to surgery. But, in tumour foci less than 3 cm or in patients in whom the perioperative risks were high (and they presented with tumor foci less than 3 cm and 3 foci), RFA proved to be a better alternative to surgery. RFA, when used percutaneously, is a cheaper procedure as compared to surgical resection. It can be performed on an out-patient basis with a maximum of 24 hours of observation. Local anesthetic or slight sedation may be employed. Greatest advantage of RFA is its ability to cause tumour degradation. Its results are not well known in our country. Under the existing financial system, RFA is not feasible.]

[Use of plain and intravenous contrast material multidetector CT examinations in acute abdomen]

TÓTH László, TÓTH Géza, TURUPOLI Emőke, LOMBAY Béla, PAVLIKOVICS Gábor

[Through most of Europe, multidetector computed tomography is used as the first-line modalitiy for examining the acute abdomen. Acute abdominal pain, symptoms referring to abnormal bowel movements, gastrointestinal bleeding, worsening general state, and other typical clinical signs require quick and precise diagnosis since these conditions are frequently life-threatening. The sensitivity and specificity of CT examinations have significantly improved due to the development of the machinary. Thus, the scope of indications are also expanding. Almost all acute abdominal disorders, that may lead to an acute surgical procedure, can be diagnosed with the help of multidetector CT. Unnecessary surgical procedures, the risk to the patients and also the cost of hospitalization can be reduced using multidetector CT examination.]

[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.]

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.

[Benefits of SGLT-2 inhibitors: beyond glycemic control]

BALOGH Zoltán, SIRA Lívia

[In the recent years, according to international and Hungarian guidelines, in addition to lifestyle modification, metformin is the preferred initial glucose-lowering drug for most people with type 2 diabetes, if not contraindicated. Sodium glucose co­transporter-2 inhibitors have been shown to reduce progression of chronic kidney disease, or kidney failure, as well as the risk of hospitalizations for congestive heart failure and (mainly in secondary prevention) cardiovascular death in patients with type 2 diabetes. For major adverse cardiovascular events and for the renoprotection, there seems to be no class effect. On the other hand, a class effect of sodium glucose co­transporter-2 inhibitors is evident for hospitalization for heart failure. In this review the authors summarize novel data about sodium glucose cotransporter-2 inhibitors, and about their new perspectives in the near future.]

[A case of destructive cervical spondylarthropathy related to chronic dialysis]

BERTA Balázs, KOMÁROMY Hedvig, SCHWARCZ Attila, KAJTÁR Béla, BÜKI András, KUNCZ Ádám

[A case of a 61-year-old male patient suffered chronic renal failure and dialysed for 23 years with destructive cervical spondylarthropathy is presented. The patient presented with sudden onset of cervical pain radiating into his shoulders without neurological deficits. CT and MRI of the cervical and thoracic spine revealed severe destructive changes and compressive fractures of C6 and C7 vertebrae which caused the narrowing of the nerve root canals at these levels. A 360-degree fixation was performed to treat the unstable fracture and the patient’s pain (C6 and C7 corpectomy, autolog bone graft replacement of the two vertebral bodies, anterior plate fixation and posterior instrumentation with screws and rods). Postoperatively the patient had no significant pain, no neurological deficit and he was able to manage independent life himself. During the immediate follow-up CT of the neck showed the satisfactory position of the bone graft and the metal implantations. The 6 months follow-up CT revealed the anterior migration of the two screws from the Th1 vertebral body and 2 mm ventral elevation of the caudal end of the plate from the anterior surface of the Th1 vertebral body. The 1-year follow-up could not be performed because the patient died due to cardio-pulmonary insufficiency. This is the second Hungarian report of a chronic dialysis related severe spondylarthropathy which may cause pathologic fractures of the vertebral bodies. The typical radiological and histological findings are discussed. This disease affect patients’ quality of life and the conservative treatment alone seems to be ineffective in most cases. Based on the literature and personal experiences, the authors suggest 360-degree fixation of the spine to provide sufficient stability for the vertebrae of ”bad bone quality”, and early mobilisation of the patient can be achieved.]

Psychoneuroimmunology and the embodied mind

SZABÓ Attila

One of the major philosophical aspirations in contemporary consciousness research is to find a framework of explanation that could successfully address the problem of mind-body relations. Descartes is often regarded as the father of dualism in modern philosophy of mind. Phenomenology and embodiment may dissolve the problem of dualism in the waters of the experiential features of the life-world and the subject. Recent findings in psychoneuroimmunology have shown that somato-psychic mechanisms exist through which bodily stimuli are translated into neuropsychological events resulting in alterations in certain behavioral patterns. These may as well include changes in the qualitative features of the lived body (Leib) resulting in an overall change in the subjective experience. The application of modern embodiment theories in life sciences has the potential to create a novel, fruitful and heuristic approach, which may help us unveil features of the “mind-body phenomenon” that have been hidden so far. In this paper, I will try to briefly outline a possible analytical framework on the grounds of classic - Husserlian and Merleau-Pontian - phenomenology and biomedical sciences.
