[LONG-TERM RESULTS OF ENDOSCOPIC SPHINCTEROTOMY - EFFECTS OF THE TRANSECTION OF BILE PAPILLA]

DÖBRÖNTE Zoltán

[The abolishment of the choledochoduodenal pressure gradient due to endoscopic sphincterotomy results in the enhancement of the enterohepatic circulation of the bile salts, in the reduction of the cholesterol saturation index and in the modification of the gallbladder function: the reduced gallbladder storage time and the increased ejection fraction facilitates gallbladder emptying. On the contrary, bacterial colonisation of the bile ducts due to duodenobiliary reflux plays a causative role in the increased risk of pigment stone formation. However, when the biliary tree is well-drained, no clinically relevant chronic inflammation develops, furthermore there is no evidence for an increased cancer risk caused by the duodenobiliary reflux. Long-term complications may occur in about 12%, as the recurrence of common bile duct stones, post-EST papillary stenosis, and biliary symptoms caused by retained gallbladder stones. Risk factors for recurrence of bile duct stones are juxtapapillary duodenum diverticulae and persistently dilated bile ducts being the main reason for papillary restenosis and sphincterotomies are mainly performed because of papillary stenosis. In cases of retained gallbladder with stones patency of the cystic duct and contractility of the gallbladder are important predictive factors of late gallbladder complications as it was confirmed by our investigations. Accordingly, small gallbladder stones may pass spontaneously after EST. The indication of a cholecystectomy following EST should be considered individually, particularly in elderly patients. As 30-year-experience confirms, EST is a safe and effective treatment of choledocholithiasis and papillary stenosis even in the long term, and also in young patients. Regular follow-up of patients with high risk for recurrent biliary symptoms is recommended to detect late complications and treat them endoscopically in time.]

[THE SIGNIFICANCE OF THE CARE OF CHILDREN WITH CLEFT LIP AND PALATE IN THE GENERAL PRACTICE]

HIRSCHBERG Jenő

[The cleft lip and palate (i.e. facial cleft) is a frequent and distorting abnormality. The basics of the successful management are the early introduction of therapy and a well-trained team with all relevant specialists included (surgeon, otolaryngologist, orthodontist, speech therapist) as well as good collaboration with the parents and general practitioners being also an important factor. The author with his co-workers has performed more than 6000 surgeries in about 3500 children with facial cleft in the last 45 years and has treated 60-70 patients annuallly with velopharyngeal insufficiency without cleft. According to his experience and international data he summarizes the etiology, pathomechanism of facial clefts and discusses its symptoms, functional consequences and the surgical and conservative solutions are suggested. The recent Hungarian prevalence is 1:500. Specific prevention does not exist, the 5-6% recurrent cleft risk may be decreased to half by administration of folic acid. The generally accepted timing of the lip plasty is the 3-month age. The palatoplasty may be performed in one or two stages, but closure of the velum should be made before the development of speech by all means. The logopedic treatment (speech therapy) should be started, if the speech disorder is already obvious and the child is able to cooperate with the speech therapist. If conservative therapy is unsuccessful, (velo)pharyngoplasty is proposed at the age of 5. The orthodontic treatment should begin in mixed dentition, major nose correction and oral surgery are allowed only after puberty. Just because of a cleft the infant does not aspirate, the brestfeeding is beneficial and could be performed in most cases. Regular hearing control is recommended because of frequent ear and hearing problems. It is suggested to provide the parents with written instruction about outcome, prognosis and timetable of management, which could be helpful also for the general practitioners.]

[CURRENT PRACTICAL VACCINOLOGY]

JELENIK Zsuzsanna

[The author deals with the current situation and new trends of vaccinology by focusing on the interests of practitioners. The main topics are the changes of antigens (such as pertussis, measles, or poliomyelitis) to provide better efficacy and milder reactogenity or less adverse events. Purifying the vaccines, like thiomersal and human proteins free vaccines is another proven method to achieve better safety. New antigens e.g. Rota, Lyme, meningococcus B are in the pipeline of vaccinology. The aim of producing a combined vaccine is to achieve immunity against more diseases with less inconvenience for the patient, while achieving higher vaccine coverage (DPT-Hib-HBV-IPV). The epidemiological and clinical experiences will influence the current vaccine schedule such as revaccinations of MMR, and remove the need for revaccinations of BCG and hepaB. The special target groups of immunizations are the elderly and patients with chronic disease. Groups of specialists are working on the vaccine recommendation guidelines for certain risk groups. At the same time, with the successful eradication of polio in Europe the practitioners now have to face the antivaccination movement, as well. The main tools to convince people about the benefit of vaccinations are health education and information.]

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.

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.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[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.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[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.

There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]
