[Today, alternative medicine is increasingly popular among patients. Patients with liver diseases surprisingly often use complementary treatment, mainly medicinal herbs, with or without the knowledge of their physician. This is one of the reasons why doctors may not ignore alternative medicine. Another reason is that twenty to thirty percent of medicaments now used in conventional therapy were originally produced from herbs. This means that some of the herbal medicines now applied in alternative therapy may become a conventional drug in the future. This paper reviews publications of evidencebased medicine on herbal medicines most often used in the treatment of liver diseases, including silymarin, glycyrrhizin, phyllantus amarus, CH- 100, LIV.52, sho-saiko-to, bin-gan, compund 861 and oxymatrine. It is important for physicians to be also knowledgeable about potentially hepatotoxic medicinal herbs.]

[Type 2 diabetes is caused by increased insulin resistance coupled with the disturbance of the secretion function of beta-cells. While the importance of insulin resistance has been emphasized in the last two decades, the pathogenetic role of beta-cell dysfunction has received less attention. Regarding this latter, several underlying mechanisms have been implicated, including increased secretory demand due to insulin resistance, glucose toxicity, lipotoxicity, islet cell amyloid deposition, and insulin resistance of the beta-cells themselves. In the milestone UKPDS (United Kingdom Prospective Diabetes Study) trial the metabolic status of the patients gradually deteriorated after 1 to 2 year of temporary improvement despite of an intensive sulfonylurea, insulin or metformin treatment. Progression of the disease could be slowed down but not stopped, which was attributed to progressive beta-cell failure. In this regard the insulinsensitizer thiazolidinediones, having recently joined the therapeutic palette, are promising because they protect and spare beta-cells through several ways. However, as the disease carrier progresses, it can reach a point when without using insulin the treatment cannot be successful anymore. Early use of thiazolidinediones may result in a marked delay of this point. This concept is supported by studies completed so far, and further clinical trials are ongoing so as to strengthen the evidence.]

[The risk of thrombosis is increased about 5 to10 times during pregnancy and in the puerperium. Beside the classic risk factors, this is also due to special obstetrical causes. Delivery, especially Cesarean section further increases susceptibility to thrombosis. Prophylactic or therapeutic anticoagulant treatment can significantly reduce maternal and fetal morbidity and mortality. Just like in the non-pregnant state, subcutaneous low molecular weight heparin or intravenous or subcutaneous unfractionated heparin is recommended in pregnancy if anticoagulation is indicated. Warfarin is contraindicated in the first trimester because of its teratogenicity and also in the third trimester because of its long-lasting effect. Heparin does not cross the placenta, but its long-term administration may cause several side effects. Dosage, starting time and duration of the treatment depend on the measure of the risk of thrombosis. In certain cases (such as antiphospholipid syndrome) anticoagulant therapy is supplemented by low-dose acetylsalicylic acid. The date of delivery can be electively planned to minimalize bleeding and thrombotic complications. Vaginal delivery is preferred because of its lower risk of bleeding compared to Cesarean section. Intensity of anticoagulant therapy in the peripartum period should depend on the risk of thrombosis. The third phase of delivery should be actively driven by giving oxytocin to avoid bleeding complications. Since anticoagulant therapy is often continued during breast-feeding, it is important to know that neither warfarin, nor heparin is secreted in milk. When planning the treatment, each case requires individual consideration based on the type and number of risk factors, gestation time and, importantly, compliance of the patient.]

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

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.

[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.]
