[BCG Immunotherapeutic (BCG IT) is the first immunomodulator to be licenced in Canada, Germany and the United States for the use in the treatment of carcinoma of the urinary bladder. The product licence was granted following the conduct of a well designed efficacy study. The study was multicente red, independent and controlled with well defined end points and a long follow up period. The results clearly shows that BCG immunotherapy is significantly more effective than Adriamycin chemotherapy. There is no evidence to suggest a difference in severity of toxicities between BCG and Adriamycin treatment groups.]

[Biological and Pathological Significance of Apoptosis (Programmed Cell Death)]

SZENDE Béla

[Programmed cell death (apoptosis) basically differs from necrosis regarding its biological significance, the morphological signs and biochemical events. Apoptosis is the result of an active cell function, so-called cell-suicide and it is observable in several biological as well as pathological processes. Enhancement of apoptosis can be achieved in malignant tumors by hormonal treatment. This explains the mode of action of hormones in tumor therapy and also contributes to the alterations in gene regulation leading to apoptosis.]

[Transesophageal and transthoracic echocardiography in aortic dissection]

LENGYEL Mária

[ The severe prognosis of aortic dissection can only be improved by early diagnosis. The role of echocardiography was assessed. Echocardiographic findings were analysed in 32 patients in whom aortic dissection was confirmed by other methods between September 1984 and July 1991. In 19 of them only transthoracic echo (TTE), in 13 patients both TTE and transesophageal echo (TEE) was performed. Control group consisted of 21 patients in whom the clinical suspicion of dissection was ruled out. The DeBakey classification was used. Among 14 acute and 18 chronic cases type I was confirmed in 9, type II in 15 and type III in 8. The sensitivity of clinical suspicion, TTE, TEE and angiography was 34, 72, 92, 94% resp. TEE correctly identified the types, entry and reentry sites, false lumen and left coronary ostium. TTE was valuable in the detection of complications and of etiologic factors of dissection. Hypertension (12) and Marfan's syndrome (7) were the leading etiologic factors. As previously has been reported in the diagnosis of aortic dissection TEE was a safe and reliable technique. It was superior to TTE and was as correct as angiography. The combined use of TTE and TEE is recommended in each case of clinically suspected dissection. The importance of the echocardiographic detection of cardiac complications and etiologic factors is emphasized in the management and prevention.]

[Oral symptoms in the early diagnosis of leukaemias]

GYURKOVICS Csilla, BÁNÓCZY Jolán

[Diseases of the haemopoetic system are often preceeded and/or accompanied by clinical changes in the oral cavity, which, as first signs of the disease, might be of important diagnostic value. Primary oral findings are characteristic mainly of acute leukaemias, such as haemorrhagies, petechias, ecchymoses, ulcera, gingival hy pertrophy, painful gingiva, tooth mobility, candidiasis, herpes simplex infection, lymph node enlargements. Oral manifestations of chronic leukaemia may also arouse the suspicion of a haemopoetic disease. Applied cytostatic therapy might aggravate the condition of oral manifestations. ]

[Peritoneal dyalisis in hungary]

KARÁTSON András, MAKÓ János

[Traditional intermittent peritoneal dialysis in patients with chronic uremia lasts for 8 to 10 hours three times a week. In 1976 Popovich et al. outlined the principle of CAPD (Continu ous Ambulatory Peritoneal Dialysis), a technique giving good results in the removal of water and toxic substances. The procedure is used in 19 000 patients in US and in 9600 patients in Europe. In early 1991 the technical conditions and the number of patients receiving peritoneal dialysis were surveyed in the Hungarian nephrological and dialysing units. Not only the number of patients with chronic uraemia (those undergoing dialysis + transplantation) is lower in this country as compared to the European average (106 versus, 236 per million people, respectively) but the distribution of patients according to the type of treatment they receive is also different. In Hungary intermittent peritoneal dialysis has been used in more than 10% of the cases for several years whereas the number of those receiving continuous peritoneal dialysis has been under 2%. (In Europe < 2% and 4–43%, respectively). The survey also included the types of solution, desinfection and connecting devices used in peritoneal dialysis, as well as the incidence of peritonitis and the administration of antibiotics . The principles of biocompatibility, the function of interleukin as well as the effectiveness and the conditions of home treatment are summarized. ]

[The role of bone morphogenetic protein in bone healing]

CSÖNGE Lajos

[The discovery of bone morphogenetic protein (BMP) in the last two decades emphasized the molecular-histogenetic mechanisms of cartilage and bone genesis and healing. Good experimental and clinical results have been obtained with application of new type bone allografts (freeze-dried, antigen extracted, de calcified, chemosterilized) which contain active BMP. Excellent osteoinductive effect and bone healing was detectable by implantation either of these grafts or pure BMP in non-weight bearing defects (bone-cysts, skull defects). Despite of the fact, that a lot of articles have been published on this field internationally, this is the first detailed review in the Hungarian literature which summarizes the most important reported information on the structure, role and clinical application of the bone morphogenetic protein.]

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

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.

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

KISS Geza Jozsef, JARABIN András János, MOLNÁR Anna Fiona, KLIVÉNYI Péter, TISZLAVICZ László, GION Katalin, FÖLDESI Imre, ROVÓ László, BELLA Zsolt

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.

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

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

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.

[The role of sleep in the relational memory processes ]

ZÁMBÓ Ágnes, PROKECZ Lídia, CSÁBI Eszter

[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.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

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.
