[The beta-blockers have been primary in cardiovascular pharmacology since the 1960's. Clinical experiences in the last 25 years have confirmed that the beta-adrenergic blockade is essential in treating the different forms of angina pectoris. Hypertension, hypertrophic cardiomyopathy, and all situations including acute myocardial infarction and some rhythm disturbances qualified by sympathetic overdrive. The beta-blockers have been shown in large scale clinical trials to reduce the cardio vascular morbidity and mortality associated with hypertension and post-infarction period. The possibility of using them as a combined therapy with a great number of other drugs without any difficulties, is very important. Toxicity is rare with beta-blockers and the side effect profile is generally good. There fore, there is no question that the risk/benefit ratio is weighted toward the benefit. Nevertheless there are some problems such as hemodynamic profile, and effects on lipid metabolism, etc. Research has advanced from the first generation to the third generation with direct or indirect effects on the vascular bed, producing strong vasodilation. Because of the above mentioned facts, it is essential to know correctly the pharmacological effects and precise pharmacokinetics, of the beta-blockers.]

[On the basis of a case report, the clinical picture, pathologic characteristics and possible histogenesis of ovarian strumal carcinoid are discussed. A 3 mm strumal carcinoid, i.e. thyroid tissue intimately mixed with a calcitonin-secreting neuroectodermal tumour, was found in a mature ovarian cystic teratoma of a 38 year old woman. Although the thyroid component demonstrated a typical normal light microscopic appearance, no thyroglobulin and thyroxine were found immunohistochemically. Immunoreactive calcitonin was demonstrated within the tumour cells, even in the transitional zone of the biphasic tissue elements. No amyloid was detected. The argentaffin and argyrophilic reactions were negative. The close relationship between functionally imperfect thyroid tissue and a neuroendocrine marker-secreting tumour seems to be concordant with the theory of the existence of a pluripotential stem cell capable of differentiating multidirectionally.]

[As a technique, is one of the indispensable means of supportiv therapy. Possibilities and approaches representing new trends of up to date therapy are offered by its application. Such approaches are, the nonsubstitutive application of IVIG, or exploiting the advantages of the functioning LAK and TIL cells. However, the authors also point out dangers of this technique, therefore plasma exchange should be applied only after thorough consideration. ]

[The primary author spent one year at the Vascular Department of Nurenberg Town Hospital where an opportunity presented it self to get acquainted with a new surgical method. The eversion endarterectomy of the carotid artery has been developed by the Nurenberg team in 1985. Since that time more then 1500 operations of this type was performed. Using the experiences gained in Nurenberg, the author introduced this new method at the Budapest Cardiovascular Surgery Clinic as well, and from January 1, 1991 until June 30, 1992, 213 operations were performed. Concerning short term results the new method is acceptable compared to the traditional methods. Owing to the method being a new one, long term results can only be read about from 2 authors. After a five year postoperative period restenosis of 1,3 percent was found after 212 operations by Kieny and after 105 operations, a 1.9 percent was reported by Kasprzak. These results seem to be encouraging if they are compared to the 10–25% restenosis rate of traditional operations. ]

[Within 30 days of the infarct, 12.2% of the placebo group and 6.4% of the APSAC group had died. The active agent reduced mortality at 30 days by a mean of 47.5% (21-65%) within a 95% confidence interval. Side effects and adverse effects were rare.]
Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.
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.
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.
[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

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.
