[Necrotizing enterocolitis in neonatology: comparing the role of X-ray and ultrasonographic examinations]

JENEI Mónika, VÁRKONYI Ildikó, NYITRAI Anna, SZABÓ Miklós, BOKODI Géza, KIS Éva

[INTRODUCTION - The authors’ purpose was to analyse the role of abdominal ultrasonography (US) in the diagnosis of necrotizing enterocolitis (NEC). They have compared the sensitivity of the current standard diagnostic modalities for this clinical entity: plain abdominal radiography and abdominal US. For a more objective comparison, they created an US scale along with utilising the score system based on abdominal radiography which was published recently. PATIENTS AND METHODS - 46 out of 76 neonates having both clinical and radiological diagnosis of NEC had comparable radiographic and sonographic examinations between June 2006 and October 2009. The authors created a 10-grade US score system, in which sonographic signs of NEC are listed in order of severity, corresponding, where possible with the radiographic scale that was available. The findings were scored individually, then the distribution of scores and their relationship to each other were analysed. For further analysis four groups of severity based on the scores were created with the following categories: mild, moderate, severe and very severe. After graphical representation of the groups, the relationship of the groups created on the basis of scoring the findings by the two diagnostic methods were examined. RESULTS - According to this analysis both abdominal radiographs and sonographs are suitable for diagnosing NEC, which has been justified with statistical data. When analysing the severity groups the authors proved that the two methods diverge in judging groups 3 and 4, thus severe and very severe. The distributions of severity groups formed by the two imaging modalities are different, (P<0,01); and the proportion of group 3 and group 4 is different in case of US and radiographic examinations (P=0.003). CONCLUSIONS - Abdominal sonography and radiography are equally suitable diagnostic methods for diagnosing NEC, and the two methods match each other very well. In cases of mild state, the severity of the disease was found to be the same with both methods, but US allows more sensitive differentiation of serious cases. It is very sensitive in detecting perforations, so it could play a role in determining the indication of surgery.]

[Investigation of colon-transit in children with chronic idiopathic constipation]

KÓCSÁK Elvira, GOMBOS János, POREMBA Beáta

[Constipation is a very common problem in childhood with diverse etiology. Most of the cases can be attributed to functional constipation. The types of chronic idiopathic constipation (CIC) are as follows: slow colonic transit, functional fecal retention, combination of the two and constipation which is predominant in irritable bowel syndrome. The first step in diagnosing/treating the condition should involve the exclusion of primary organic causes, as well as metabolic, neurological and iatrogenic ones. Then special anorectal physiological investigations are needed. In our laboratory, the aim of radionuclide study is to demonstrate the two types of CIC, the slow colon transit (SCT) and the functional fecal retention (FFR). Such evaluation makes it easier for the clinician to plan appropriate treatment. The radionuclide study is conducted as follows: after adequate pretreatment, Tc-99m Fyton is administered orally, and images are collected at 2, 6, 12, 24, 30 and 48 hours following administration. After the evaluation of the specific studies, exploration of the causes and exact diagnosis are established. Appropriate treatment is always planned individually. We would like to demonstrate this by presenting 3 cases.]

[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.]

[CONTEMPORARY THERAPY OF COLORECTAL TUMORS]

LAKATOS László, LAKATOS Péter László

[Chemo-radiotherapy of colorectal tumours has become a successful field in oncology. The cornerstone of the treatment has remained the 5- FU containing regimes, however the improvement of administration protocols (e.g. continuous infusion, oral administration) and the addition of biomodulating agents has improved efficacy considerably. The recent availability of newer agents, like irinotecan and oxaliplatin has significantly improved survival of advanced (metastatic) colorectal cancer, extending up to 20 months average survival, also being a consequence of the more aggressive treatment of hepatic and lung metastases. The adjuvant chemotherapy of Dukes’ C tumours has become standard, while the treatment of high-risk B2 tumours is also recommended. Neoadjuvant/adjuvant chemo-radiotherapy improves the prognosis of rectal tumours, however the optimal regime has not yet been determined. The combination of two or more agents is superior to monotherapy and the route and sequence of administration may also influence efficacy. The biological agents of the near future including cetuximab (directed against epidermal growth factor receptor) and bevacizumab (a monoclonal antibody to vascular endothelial growth factor) may further improve survival in poor prognosis patients. The use of the new drugs is limited at the moment by their high costs.]

[Differential diagnosis of atypical Parkinsonian syndromes]

CSÓTI Ilona, FORNÁDI Ferenc

[Atypical Parkinson syndromes are distinguished from idiopathic Parkinson disease by insufficient or missing response to dopaminergic replacement therapy and therefore they have significantly unfavorable prognoses. Early differential diagnosis is very important for the patient. It enables the therapist to give suitable consults, to avoid unnecessary or inappropriate therapy, which are not free of medication side effects and furthermore facilitates the selection of adapted symptomatically medical and physical measures of treatment. In case of future development of neuroprotective or causally therapy strategies correct diagnosis will allow an early start of therapy. The differential diagnosis separation of the three clinical pictures from the idiopathic Parkinson disease with clinical criteria might be difficult in the early stage of disease. Additional neuroimaging and nuclear medical investigations may support the clinical probable diagnosis.]

[Who are the happy female physicians in Hungary?]

GYŐRFFY Zsuzsa

[BACKGROUND - The female Physicians’ well-being and happiness has become the latest researching field of the “Physicians studies”. In Hungary the researches haven't focused on this subject. Our aim was to examine the subjective well-being of the Hungarian female Physicians. METHODS - Representative, cross-sectional, quantitative survey on a representative sample of female Physicians (N=408). Modified version of WHO Well- Being Index was performed to measure of subjective Well-Being. RESULTS - We have found that the key to the Hungarian female Physicians’ wellbeing is the “time”. Significantly higher rate of well-being is associated with reduced work-hours (8 hour or less, p=0.000), and duty hours (p=0.042), having one hour free time daily (p=0.021) and they satisfied with the time of doctor-patient interaction (p=0.021). The higher rate of Well-Being scores haven't associated with age, marital status, number of children and the speciality. CONCLUSION - Similarly to the national trends, the Hungarian female Physicians' well-being is depending on the work and the satisfaction with work. The satisfied healer is the key of the health system therefore the future studies and the prevention and intervention have to focus on the Physicians’ well-being.]

[Perinatal faulty hormonal imprinting: early impact, late consequences]

CSABA György

[The description and basic study of hormonal imprinting were the first in the series of research, which led to the recognition of the role of perinatal chemical effects in the late (adult age) manifestation of some diseases and inclination to diseases. Today it is clear, that certain pathological states, as obesity or diabetes, hypo- or hyperactivity (autoimmunity and allergy) of immune system can be deduced to perinatal (hormonal or metabolic) imprinting. The perinatal hormonal (chemical) imprinting takes place at the first encounter between the developing hormone receptor and the target hormone which sets the binding capacity of the receptor for life. In the critical periods of ontogeny (in addition to the perinatal imprinting) it can be developed at weaning, in adolescence and in continuously dividing and differentiating cells during the whole life. It is provoked by considerable quantitative differences of the physiological hormone or the presence of strange target-hormone-like molecules. The faulty hormonal imprinting leads to the adult-age diseases at any time of life and is inherited epigenetically to the progeny generations. Faulty hormonal imprinting always could be present in earlier times however, at present, because of the erroneous multiplication of endocrine disruptors in the environment, nutrition and medicine, its importance is continuously growing. The effects of faulty hormonal imprinting seem to be dangerous however, it can be imagined in the far future also a positive effect by the transformation of the human endocrine system at an evolutionary route. In the metabolic or immunological imprinting as well, as in the DOHaD (Developmental Origins of Health and Disease) the foremost recognized hormonal (chemical) imprinting is materialized.]
