[The constipation is a frequent disorder, which often requires gastroenterological examination. Colon transit study and defecography are indicated in case of making difference between slow colon transit time and outlet obstruction. The method, the mode of administration of the radiopaque markers and the evaluation of the radiological study are discussed. Radiopaque markers ingested on the first day are followed by abdominal X-ray taken at regular times. The normal value of the colon transit time is less than 70 hours. The etiology of constipation has to be clarified by functional examinations, since the treatment of outlet obstruction is different from slow transit constipation. To determine the large bowel transit time is necessary also in the differential diagnosis of slow colon transit. The method is a simple, reliable and easily reproducible.]

[Multisegmental tuberculous spondylodiscitis in a patient with Helicobacter pylori infection]

SZÁNTÓ Dezső, SZŰCS Gabriella, DITRÓI Edit

[INTRODUCTION - Prospective randomized examination has been verified association between asymptomatic chronic Helicobacter pylori infection and systemic vascular inflammation and endothelial dysfunction in certain cases. CASE REPORT - A case of a 71 year-old female patient is described with proven coexisting primary tuberculous bronchoadenitis, secondary tuberculous spondylodiscitis and Helicobacter pylori infection as a cause of uncertain abdominal disorder. The patient's height decreased by 9 cm during 6 months, since the onset of the symptoms. The diagnosis was based on respiratory function test, positive rapid ureal test, bronchoscopy, cytologic and microbiological examinations. On dorsolumbal spinal plain films showed wedge, biconcave crus and mass deformities of nine vertebras. High serum level of CRP and C3 complement was suggestive of acute reactive inflammation. Before the introduction of drug therapy an MR examination was planned, however the patient died of an acute myocardial infarct on the 8th day after admission The postmortem findings proved the presence of pulmonary and vertebral tuberculosis, there was no evindence of aortocoronal and spinal vasculitis. The epispinal tissues were not involved. CONCLUSION - The patient’s case history, autopsy findings and the literature data are suggestive of the role chronic Helicobacter pylori infection in the development of spondylodiscitis and the deterioration of the disease.]

[Diagnostic and therapeutical possibilities in constipation]

ILLÉS Anita, KIRÁLY Ágnes

[Constipation is a common gastrointestinal problem. The prevalence of symptoms related with constipation fluctuates from 3 to 20 per cent. Constipation occurs more frequently in the elderly people and in females and more frequent in case of inactivity and less fiber intake. Assesment of patients with severe constipation includes specialized investigations. Exclusion of primary organic causes has to be the first step, then metabolic, neurological and iatrogenic causes (such as medicament side effects, etc) have to be excluded. After these considerations special functional gastroenterological investigations are needed which contribute to the diagnosis and differential diagnosis of the cause of the constipation. Anorectal manometry, ballon expulsion test, defecography and colon transit studies allow us to distinguish between slow colon transit, colon inertia, different subtypes of outlet obstruction, and the constipation predominant irritable bowel syndrome. The evaluation of these specific studies leads to the exact diagnosis and appropriate treatement for their problem can be given to the patients, which always has to be individually planed in all cases.]

Investigation of risk factors, topographic location and stroke mechanisms of unilateral isolated and posterior cerebral ARTERY thalamic infarcts

GÖKCAL Elif, SENGUL Yildizhan, USLU Ilgen Ferda

Aim - In this study, we aimed to examine the risk factors, topographic features and stroke mechanisms of acute ischemic unilateral infarcts of thalamus. Methods - Patient with isolated thalamic infarct and those with posterior cerebral artery (PCA) infarction who were admitted to our hospital between January 2014 and January 2017 with acute unilateral thalamic infarction (TI) were included in this study (isolated thalamic infarction/ isolated TI; thalamic and posterior cerebral artery infarction/PCA+TI). Demographic characteristics and vascular risk factors of the patients were determined. Thalamic infarct areas were recorded topographically as anterior, posteromedial, ventrolateral, posterolateral, more than one area, and variant areas. Stroke mechanism was determined according to the criteria of „Trial of Org 10172 in Acute Stroke Treatment” (TOAST). Patients with isolated TI and PCA TI were compared according to risk factors, stroke mechanism and infarct topography. Results - Forty-three patients with a mean age of 63.3 ± 14.5 years were included in the study. Twenty-eight patients (60.1%) were found to have isolated TI and the remaining 15 patients (34.9%) had PCA+TI. 32.1% of patients with isolated TI had sensory symptoms on presentation, and 60% of patients with PCA-TI had sensorimotor symptoms. The mean age, the mean score on National Institutes of Health Stroke Scale (NIHSS) and the mean frequency of atrial fibrillation were higher in PCA+TI patients than in isolated-TI patients (p: 0.04, p: 0.004, p: 0.02 respectively). 32.6% of the patients had ventrolateral, 30.2% had posteromedial involvement. Ventrolateral topography was seen in 46.7% of the PCA+TI patients, while posteromedial topography was seen in 39.3% of the isolated-TI patients. 53.6% of the isolated-TI had small vessel disease etiology, while 40% of the PCA+TI had cardioembolic etiology, and the other 40% had large artery atherosclerosis. Conclusion - Our study showed that the most ommon stroke mechanism in patients with thalamic infarction is the small vessel disease. Isolated TI and PCA+TI patients differ in terms of etiologic mechanism and infarct topography. Variant territorial involvement and multiple area involvements can be quite common in thalamic infarcts.

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]
