[The objectives of this paper are to discuss the safety and tolerability of combined infusion -Neodolpasse(®) - containing nonsteroidal antiinflammarory drug, diclofenac and central muscle relaxant orphenadrin on the basis of recent data. The author reviewed phase IV randomised, controlled studies published on Medline and in the Hungarian literature. On the basis of the available data, diclofenac/orphenadrin infusion is an effective and safe analgesic, which is easy to administer and to combine with other painkillers in acute low back pain and other painful rheumatic conditions, as well as postoperative pain.]
[In rheumatoid arthritis, the inflammation and damage of multiple joints can lead to generalised osteoporosis. This process is mostly mediaated by cells and cytokines that are also important for maintaining inflammation, by inhibiting bone formation as well as stimulating bone resorption. Data from the literature show that biological therapies that effectively decrease inflammation can also stimulate bone formation and inhibit bone resorption. This results in an increased bone density and bone protection, which is highly important to prevent subseqent fractures.]
[The aim of this study is to evaluate the relationship of serum sclerostin levels with age, cystatin C, bone mineral density (BMD) and biochemical markers of bone turnover in healthy Hungarian men over 50 years of age. We determined serum levels of sclerostin and examined its relationship with age, cystatin C, osteocalcin, C-terminal telopeptides of type-I collagen, procollagen type 1 amino-terminal propeptide, 25- hydroxyvitamin D, parathyroid hormone, and L1-L4 (LS) and femur neck (FN) BMD data available from 194 randomly selected ambulatory men belonging to the HunMen cohort. In the study population as a whole (n=194; age (median, range): 59 (51-81) years), statistically significant correlation was found between sclerostin and age (r=0.211; p=0.003), cystatin C (r=0.246; p=0.001), FN-BMD (r=0.147; p=0.041) and LS BMD (r=0.169; p=0.019). Compared with middle-aged men (age: ≤ 59 years, n=98), elderly men (age > 59 years, n=96) had significantly higher serum sclerostin levels (67.8±15.9 pmol/l vs. 63.5±14; p=0.047). Among men with normal (T score >-1,0) FN-BMD, the elderly had significantly higher serum sclerostin levels as compared with the middle-aged (70.4±17 pmol/l vs. 63.9±11.5 pmol/l; p=0.019). Furthermore, among the elderly men cystatin C was the only significant predictor of serum sclerostin levels (standardized regression coefficient (béta) = 0,487; p<0,001). Our results show that in the studied healthy elderly cohort sclerostin levels significantly increase with age, along with the deterioration of kidney function as determined by plasma cystatin C levels. ]
[Recognition of the characteristics of arthritis is crucial for making a correct diagnosis. Several aspects of the history and physical examination could help the diagnosis, such as the mode of onset (acute, insidious), duration of symptoms (self-limiting, chronic), number of affected joints (mono-, oligo-, polyarthritis), distribution of joint involvement (symmetrical, asymmetrical), localisation of affected joints (axial, peripherial) and sequence of involvement (additive, migratory, intermittent). Other important aspects for the correct diagnosis are the characteristics of the patient (gender, age, family history) and the presence or absence of extra-articular features of disease. The articular pattern may change with time in the course of a disease, and the single clinical pattern of joint disease may correspond to more than one diagnosis. Evidence of some distinct articular patterns may limit the spectrum of diagnostic options and reduces unnecessary diagnostic testing. The diagnostic process may require the addition of laboratory examination, imaging techniques, and other tests to refine the analysis. In this article, we report a case where joint punction and histological elucidation was necessary to make the correct diagnosis, because a syndrome of acute, destructive sterile arthritis mimicking articular infection might be present in a variety of joint disorders. In this paper, we highlight those characteristics that are distinctive for particular rheumatological disorders, in order to help starting treatment early.. In a substantial number of patients the cause of the diseases remains undetermined. However, a detailed anamnesis and physical examination remain the cornerstone of a diagnostic evaluation.]
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.

[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.]
Evidence suggests that pathogen-associated pattern recognition receptors (Toll-like receptors, TLRs) are implicated in the pathophysiology of schizophrenia. TLRs are important in both peripheral immune responses and neuronal plasticity. However, the relationship between peripheral TLR expression and regional brain volumes is unknown in schizophrenia. We therefore assessed 30 drug-naïve, first-episode patients with schizophrenia. TLR4+/TLR1+ monocytes were measured using flow-cytometry. High resolution magnetic resonance images (T1 MRI) were obtained and analyzed with FreeSurfer. Results revealed significant negative correlations between the percentage of TLR4+ monocytes, mean fluorescent intensities, and brain volumes in frontal and anterior cingulate regions. The measures of TLR1+ monocytes did not show significant relationships with regional brain volumes. These results raise the possibility that abnormal TLR-activation is associated with decreased brain volumes in schizophrenia.
CANOMAD (chronic ataxic neuropathy, ophthalmoplegia, M-protein agglutination, disialosyl antibodies) syndrome is a rare polyneuropathy. IgM paraproteins react with ganglioside-containing disialylated epitopes resulting in dorsal root ganglionopathy and B-lymphocyte infiltration of cranial and peripheral nerves. Clinical features include ataxia, slight muscle weakness, areflexia, sensory- and cranial nerve symptoms. Case studies have reported the efficacy of rituximab and intravenous immunoglobulin (IVIg) treatments. We present the case of a 57-year-old man, who had difficulty walking, with numbness and clumsiness in all limbs. He had areflexia, vibratory sensation loss and ataxia. Laboratory tests showed IgM monoclonal components and disialosyl antibodies in the serum. Nerve conduction studies indicated severe sensorimotor demyelinating polyneuroradiculopathy. Despite IVIg and rituximab treatments, the patient’s disease course gradually worsened and he died of respiratory failure. Neuropathological examination revealed dorsal column- and dorsal root atrophy with mixed mononuclear cell infiltration. This article aims to draw attention to this syndrome, and the use of early potent immunosuppressive treatment to improve patients’ quality of life.
Myasthenia gravis (MG) and Guillain-Barré syndrome (GBS) are autoimmune disorders that may cause weakness in the extremities. The coexistence of MG and GBS in the same patient has rarely been reported previously. A 52-year-old male presenting with ptosis of the left eye that worsened with fatigue, especially toward evening, was evaluated in our outpatient department. His acetylcholine receptor antibody results were positive, supporting the diagnosis of MG. His medical history revealed a post-infectious acute onset of weakness in four extremities, difficulty in swallowing and respiratory failure, which was compatible with a myasthenic crisis; however, his nerve conduction studies and albuminocytologic dissociation at the time were compatible with GBS. With this case report, we aimed to mention this rare coincidental state, discuss possible diagnoses and review all other similar cases in the literature with their main features.
