[The multidisciplinary pathological examination of colorectal carcinomas - From the biopsy sample to the K-RAS mutation analysis]

BOGNER Barna

[BACKGROUND - The role of pathologist in the reporting of colorectal carcinomas (CRC) has dramatically changed in the past 20 years. This change has been generated by the enormous progress in the surgical, radiological, oncological and pathological techniques and their interactions. AIM - To interpret the role of pathologist in the colorectal multidisciplinary team. METHODS - The most important histopathological prognostic and predictive factors, the surgical planes, the involvement of circumferencial margin, the regression grade after neoadjuvant chemoradiotherapy were assessed in 964 patients treated with operable colorectal cancer during 2001-2007 in the County Hospital of Baranya and the four nearby city hospitals. RESULTS - Most of our patients (>75%) were treated with advanced stage tumors. The lymph nodes were harvested through careful slicing, visual inspection and palpation - accordingly the average lymph node count increased from 7.45 to 19.0. After using elastic fibre stain we detected twice as much vascular invasion then before. The results of the surgical quality after TME and APER were somewhat dissapointing. Although the ratio of the specimens resected in the mesoretal fascial plane was comparable to the international results (39.8%), the ratio of resections in the muscularis propria plane was unacceptably high (47.8%) and it was more pronounced (50-100%) between the low volume surgeons of the small city hospitals. The involvement of the circumferencial resection margin was affected by the advanced pT and pN stage, the vascular invasion, the surgical plane, the type and number of resection performed by the surgeons, the regression grade after preoperative chemoradiotherapy and the gender. CONCLUSIONS - In addition to the traditional histopathological features the pathologist has to investigate the quality features of the preopreative assessment, the surgical planes of excision and the grade of regression after neoadjuvant chemoradiation and feed back these results to the members of the CRC multidisciplinary team. The optimal treatment of the CRC can be achived only in this setting.]

[Incretin based therapies from a clinician’s view]

KIS János Tibor

[The incretin based therapies give new and promising opportunities in the care of type 2 diabetic patients. Right now two kinds of incretinmimetics and three incretinenhancers are available in Hungary. There are more and more agents and more industrial products. There are several publications about the advantages of these products, but only a few data can be found about the comparison of them. The author tries to evaluate the incretin based therapies, and tries to help the clinicians choose the right one.]

[Efficacy and safety of sitagliptin during long term treatment in patients with type 2 diabetes]

HIDVÉGI Tibor

[Due to the progressive nature of the type 2 diabetes mellitus and treatment requires prolonged lifestyle and/or pharmacologic management, the long term efficacy, durability and safety of newer antihyperglycemic agents are important considerations. Metformin is the most common prescribed oral antihyperglycemic agent (OHA) for initial therapy. Often, initial single oral agent is not sufficient to maintain good glucose control, combination of OHA are usually required to manage patients with type 2 diabetes. Incretinbased therapies (e.g. dipeptidyl peptidase 4 (DPP 4) inhibitors and analogues of glucagon like peptide 1) are newer compounds available for the treatment of type 2 diabetes. Sitagliptin is a once-daily OHA with a novel mechanism of action that targets the incretin axis. Addition of sitagliptin to ongoing metformin therapy was well tolerated and resulted in significant glycemic improvement after 30-104 weeks of treatment in patients with type 2 diabetes.]

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.

The prevalence of sarcopenia and dynapenia according to stage among Alzheimer-type dementia patients

YAZAR Tamer, YAZAR Olgun Hülya

Aim - In this study, the aim was to identify the prevalence of sarcopenia and dynapenia according to disease stage among Alzheimer-type dementia (AD) patients and collect data to suggest precautions related to reducing the disease load. Method - The study was completed with 127 patients separated into stages according to Clinical Dementia Rating Scale (CDR) criteria and 279 healthy volunteers aged 18-39 years and 70-80 years abiding by the exclusion criteria who agreed to participate in the research. Our prospective and cross-sectional study applied the CDR and mini mental test (MMSE) to patients with disorder in more than one cognitive area and possible AD diagnosis according to NINCDS-ADRDA (National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer’s Disease and Related Disorders Association) diagnostic criteria. The patient and control groups had skeletal muscle mass index (SMMI), muscle strength and physical performance assessed with sarcopenia diagnosis according to European Working Group on Sarcopenia in Older People (EWGSOP) diagnostic criteria. Results - In our study, in parallel with the increase in disease stage of AD patients, the prevalence of sarcopenia (led by severe sarcopenia) and dynapenia was higher compared to a control group of similar age. Conclusion - In chronic, progressive diseases, like AD, identification of changes in parameters, like muscle mass and strength and reductions in physical performance in the early period, is important for identification and to take precautions in the initial stages considering the limitations of the preventive effects of treatment applied after diagnosis of AD.

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.

[Sacral insufficiency fractures]

FERENC Mária, PUHL Mária, VARGA Péter Pál

[BACKGROUND - The spontaneous osteoporotic fracture of the sacrum, known as a sacral insufficiency fracture (SIF) was first described as an unrecognized syndrome of the elderly by Laurie, in 1982. Numerous case histories and a few series of cases have been discussed in medical journals; however, none have been reported in Hungary. GOAL - To delineate the leading diagnostic steps in the recognition of SIF and review the therapeutic guidelines. CASE HISTORIES, METHODS - Between January 2009 and the first six months of 2010 11 cases of SIF were diagnosed at the National Center for Spinal Disorders. We examined the clinical aspects of the illness, the radiological modalities, the fracture markings, the pace of recovery and duration. RESULTS - The 11 patients were found to have various SIF predestining etiological factors and the following classic fractures - H-type, unilateral, horizontal, unilateralhorizontal and vertical as well as a bilateral pattern. In cases often not showing obvious clinical symptoms and in cases resulting in conventional radiological examinations of low sensitivity and specificity, we used mapping techniques in setting up the exact diagnosis. CONCLUSION - If we consider SIF from patient history and known risk factors, diagnostic procedure (primer original) may be shortened and a number of unnecessary tests (biopsy) may be avoided.]
