[Bacterial contamination and irritable bowel syndrome]

NOVÁK János

[Irritable bowel syndrome (IBS) is one of the most common gastrointestinal condition, which affects 10-15% of adults in developed countries. Recent observations have raised the possibility that disturbances in the gut microbiota and/or the accompanying low-grade inflammatory state might contribute to the etiology and symptomatology of irritable bowel syndrome. Some studies indicate that small intestinal bacterial overgrowth (SIBO), as confirmed by hydrogen breath tests (HBT), is more prevalent in patients with irritable bowel syndrome than in matched controls without IBS. Although the data are conflicting, this observation has led to the hypothesis that bacterial contamination was the primary cause of IBS. As a consequence of this hypothesis, a lot of therapeutic options have found their way into the armamentarium of those who treat patients with IBS. These agents include probiotics, prebiotics, antibiotics and anti-inflammatory agents. This paper describes the various mechanisms by which changes in the gut flora might contribute to IBS and also discusses the efficacy and safety of antibiotic therapies, especially rifaximin, for treating IBS/SIBO symptoms.]

[Epidemiological surveillance systems used by international organisations in military crisis management operations]

KOPCSÓ István, KISS Antal Zsolt

[Facing new challenges and growing requirements, the renewal and adjustment of doctrines, methods and technology is an indispensable progressive need for modern militaries. In order to achieve the maximal protection of troops and conservation of fighting strength, innovation is continuous and has greatly accelerated in the whole spectrum of Force Health Protection. Owing to the development of technology, portable capabilities that had been available only in the hinterland have become available in the military medical support area. Utilising mobile information technology solutions, the continuous, real-time information flow between the tactical level medical units and the higher level medical analysts and decision makers has become technically feasible, which results in a significant widening of epidemiological surveillance capabilities as well. We discuss the current challenges of expeditionary- type military operations and their general epidemiological aspects and the morbidity reporting and monitoring systems used in international military missions. Furthermore, we overview the milestones of the development of the NATO near-real-time epidemiological surveillance system, the NATO Deployment Health Surveillance Capability, which functions as a branch of the Budapestbased multinational NATO Centre of Excellence for Military Medicine.]

[Clinical aspects of ischaemic bowel disease]

DEMETER Pál

[Decreased blood flow through the intestines leads to mesenteric ischaemia, which is characterised by cellular damage due to the lack of oxygen and nutrients. Extensive collateralisation between splanchnic vessels serves as a protective mechanism against ischaemia. Intestinal ischaemia can be classified on the basis of its timing, location and the vessels involved. Acute mesenteric ischaemia can result from arterial embolisation, arterial or venous thrombosis, or vasoconstriction secondary to systemic circulation disorder associated with hypovolaemia. Chronic mesenteric ischaemia develops as a consequence of partial or complete occlusion of splanchnic vessels. Colonic ischaemia is mainly caused by a limited circulation disorder of the inferior mesenteric artery. Mortality rates for the various forms of acute mesenteric ischaemia are different. However, early diagnosis before bowel infarction might improve survival. This paper summarises the cilical aspects, diagnosis and therapeutic options of intestinal ischaemia.]

[The new British recommendations for the treatment of lower back pain on the basis of the new NICE guidelines - comparison with the Hungarian therapeutic practice]

VERECKEI Edit, PALKONYAI Éva, SIMONCSICS Eszter, APÁTHY Ágnes, TEMESVÁRI I. Péter

[The new NICE guidelines on lower back pain emphasise the importance of clinical assessment. Radiological imaging methods are used primarily to exclude severe diseases, such as tumour, infection, trauma or inflammation. It’s crucial to inform patients and encourage them to use self-management and stay active. Pain management is guided by the analgesic ladder. A complex physical and psychological treatment is used, which involves a structured exercise programme, manual therapy and acupuncture, taking into account the preferences of the patient. Depending on the aetiology, surgical intervention should be considered in therapy-resistant cases. Finally, the authors compare the above guidelines with the Hungarian practice in this field.]

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 connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]
