[Certain viral infections, gene mutations and immune suppression are likely to play some role in the development of malignant lymphomas. The clinical stage at the time of diagnosis is a decisive factor of prognosis. The evaluation of the nodal and extranodal manifestation of the disease is performed by standardized imaging techniques. Most frequent extranodal manifestation involves the bone marrow, the lung and the gastrointestinal tract. Different imaging techniques are indispensable in monitoring the effectiveness of the treatment and in long term follow up.]

[In vitro optimization of sequences applicable for the MR examination of the gastrointestinal tract with respect to certain contrast materials]

BABOS Magor, PALKÓ András, KARDOS Lilla, CSERNAY László

[PURPOSE - Optimization of gradient-echo and spin-echo sequences in order to visualize oral contrast media for magnetic resonance imaging (MRI) of the small bowel using a 1-T unit. MATERIAL AND METHODS - Authors investigated the optimal appearance of four different potential oral contrast media (rosehip syrup, blackcurrant extract, iron(III)-desferrioxamine, cocoa) with different spin-echo and gradientecho sequences using a simple plastic model. They were searching the optimal solution by changing the parameters of the chosen sequences keeping an eye in every case on the signal-to-noise ratio, the contrast, the resolution, the artifacts and the signal intensity of the contrast materials. RESULTS - The gradient-echo sequences are suitable for imaging of the small bowel. Too short echo time should be avoided because of the increased formation of artifacts. A lot of artifacts can be eliminated using fat saturation. T2*- weighted gradient-echo sequences provide good appearance for the cocoa drink, as well as the three-dimensional gradient-echo sequence. The use of sequential gradientecho acquisition methods is advisable only in non-cooperating patients, because of their low signal-to-noise ratio. The iron(III)-desferrioxamine solution, the rosehip syrup and the blackcurrant extract are potential positive contrast agents on T1-weighted sequences. On the single-shot fast spin-echo (SSFSE) sequence the rosehip syrup and the blackcurrant extract appear as negative contrast materials. CONCLUSIONS - Authors could select and optimize the sequences suitable for each contrast material and effective in small bowel MRI. The substances used in their experimental model are not harmful for humans when administered orally, so determination of additives is the only problem remained before their use in the clinical practice.]

BERCZI Csaba, TÓTH György, VARGA Attila, FLASKÓ Tibor, KOLLÁR József, TÓTH Csaba

[PURPOSE - The aim of the study was to measure the sensitivity and specificity of computed tomography for local staging in patients underwent radical perineal prostatectomy. PATIENTS AND METHODS - 160 patients were involved in the study. Rectal digital examination, measurement of prostate specific antigen, prostate biopsy, CT, ultrasound, chest X-ray examination and bone scintigraphy were performed in every case before radical prostatectomy. RESULTS - The average preoperative prostate specific antigen concentration was 15.8 ng/ml before surgery. The average Gleason score of biopsies was 3.19. CT showed extraprostatic infiltration in 14 patients (pericapsular invasion n: 6, seminal vesicula n: 3, bladder infiltration n: 5, lymph node metastasis n: 2). The histological examination proved extraprostatic invasion of the tumour in 35 cases (pericapsular invasion n: 35, seminal vesicula n: 25, bladder infiltration n: 5). The cancer was localized in the prostate in 125 patients. Sensitivity and specificity of CT for pericapsular invasion were 14% and 98%, for infiltration of seminal vesicula 12% and 100%, and for bladder infiltration 20% and 97%. There was not a significant difference between the prostate specific antigen values (p=0.94) in cases when the tumour was confined to the prostate and when the cancer showed extraprostatic infiltration. There was significant difference between the Gleason score values between the two groups (p=0.008). CONCLUSION - The sensitivity of CT for local spread of prostate cancer is very low, thus CT is not a suitable method for the local staging before surgery.]

The etiology and age-related properties of patients with delirium in coronary intensive care unit and its effects on inhospital and follow up prognosis

ALTAY Servet, GÜRDOGAN Muhammet, KAYA Caglar, KARDAS Fatih, ZEYBEY Utku, CAKIR Burcu, EBIK Mustafa, DEMIR Melik

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

[New findings in the cortical bone biology and its role in bone fractures]

BALOGH Ádám, BHATTOA Harjit Pál

[The authors surveyed the already known factors responsible for the osteoporotic bone fragility. Then the results of using modern imaging techniques (micro-CT, high-resolution peripheral computed quantitative tomograph - HR-pQCT) and advanced computer analytic methods (finite element analysis, FEA) are presented. These data - beyond the already known fracture risk factors (age, risk of falling, bone mineral density - BMD, and fine structure damage of trabecular bone) are stressing the importance of the (micro)damage of cortical bone as a fracture risk factor, which has been still underrated. The cortical thickening and increased porosity - verified on various population samples - are increasing the risk of fractures in certain subgroups of subjects having identical BMD values, even among those, who are considered only osteopenic by the earlier classification based on BMD values. Backed with modern software batteries, the new imaging techniques are expected to enter clinical application in the near future. Pharmacologic agents with stronger cortical effect are already available and research is continuing to find new drugs to use in the management of osteoporotic patients of high fracture risk.]

GENC Fatma, ERDAL Abidin, AKCA Gizem, KARACAY Ertan, GÖKSU Özaydın Eylem, KUTLU Gülnihal, GÖMCELI Bicer Yasemin

Purpose - Nonconvulsive status epilepticus (NCSE) is a heterogeneous, severe neurological disorder of different etiologies. In this study, the outcomes of NCSE episodes was assessed in a large series of adult patients. Our objective was to evaluate relationship between Status Epilepticus Severity Score (STESS) and etiology and the role of etiological factors on predicting the outcomes. Method - In this retrospective study, the medical records of 95 patients over 18 years of age who were diagnosed with NCSE between June 2011 and December 2015 were reviewed. Their treatment and follow-up for NCSE was performed at the Epilepsy Unit in Department of Neurology, Antalya Research and Training Hospital. Etiological factors thought to be responsible for NCSE episodes as well as the prognostic data were retrieved. The etiological factors were classified into three groups as those with a known history of epilepsy (Group 1), primary neurological disorder (Group 2), or systemic/unknown etiology (Group 3). STESS was retrospectively applied to patients. Results - There were 95 participants, 59 of whom were female. Group 1, Group 2, and Group 3 consisted of 11 (7 female), 54 (33 female), and 30 (19 female) patients, respectively. Of the 18 total deaths, 12 occurred in Group 2, and 6 in Group 3. The negative predictive value for a STESS score of ≤ 2 was 93.88% (+LR 2.05 95% CI: 1.44-2.9 and -LR 0.3 95% CI 0.10-0.84 ) in the overall study group. While the corresponding values for Group 1 (patients with epilepsy), Group 2 (patients with primary neurological disorder), and group 3 (patients with systemic or unknown etiology) were 100%, 92.59% (+LR 2.06 95%CI: 1.32-3.21 and -LR 0.28 95% CI 0.08-1.02 ) 83.33% (+LR 1.14 95%CI: 0.59-2.9 and -LR 0.80 95% CI 0.23-2.73). Conclusions - This study included the one of the largest patients series ever reported in whom STESS, a clinical scoring system proposed for use in patients with status epilepticus, has been implemented. Although STESS appeared to be quite useful for predicting a favorable outcome in NCSE patients with epilepsy and primary neurological disorders, its predictive value in patients with systemic or unknown etiology was lower. Further prospective studies including larger NCSE samples are warranted.

[Burning sensation in oral cavity - burning mouth syndrome in everyday medical practice]

GERLINGER Imre

[Burning mouth syndrome (BMS) refers to chronic orofacial pain, unaccompanied by mucosal lesions or other evident clinical signs. It is observed principally in middle-aged patients and postmenopausal women. BMS is characterized by an intense burning or stinging sensation, preferably on the tongue or in other areas of the oral mucosa. It can be accompanied by other sensory disorders such as dry mouth or taste alterations. Probably of multifactorial origin, and often idiopathic, with a still unknown etiopathogenesis in which local, systemic and psychological factors are implicated. Currently there is no consensus on the diagnosis and classification of BMS. This study reviews the literature on this syndrome, with special reference to the etiological factors that may be involved and the clinical aspects they present. The diagnostic criteria that should be followed and the therapeutic management are discussed with reference to the most recent studies.]
