[DIVERTICULOSIS, DIVERTICULITIS - SYMPTOMS, DIAGNOSTICS AND TREATMENT]

NÉMETH Anna Mária, ENDER Ferenc, BANAI János

[Diverticulosis of the colon is frequent in developed countries. Decreased intake of dietary fibre have been implicated as an important pathogenetic factor. Most of the affected patients are asymptomatic but 10-20% of them have abdominal problems. Clinical manifestations range from simple, non-complicated form (abdominal pain, distension, constipation, urgency etc.) to severe complications (diverticulitis, abscess, peritonitis, perforation, haemorrhage etc.) The diagnosis and therapy of different forms of diverticular disease can be very simple but in several cases differential diagnostical problems and therapeutical difficulties may arise. The gold standard for establishment of uncomplicated diverticulosis is the barium enema or colonoscopy. In case of complicated forms non-invasive methods (US, CT scan, CT-colonography, MRI) have to be preferred. These examinations have no risk for perforation and extraintestinal pathology (air, fluid, abscess) can be detected. Colonoscopy or angiography are the methods of choice in case of haematochesia. The choice of therapy is based on clinical presentation, symptoms and pathology. Fibre supplementation is recommended for patients with diverticulosis without symptoms. In case of noncomplicated symptomatic diverticular disease fiber supplementation or cyclic administration of broad spectrum, poorly absorbable antibiotic can be effective in the prevention of inflammatory episodes and complications. If some of the severe or recurrent complications can not be treated conservatively, surgery is necessary. Prevention of diverticulosis and diverticular disease has to be emphasized. While fibre supplementation in the diet is recommended, other efficacious preventive strategies remain to be identified.]

[BENIGN SOLITER FIBROTIC TUMOR OF THE PLEURA - A CASE REPORT]

BOHÁCS Anikó, TAMÁSI Lilla, SOMOSKÖVI Ákos, MÉSZÁROS Zsolt, SÁPI Zoltán, BÁRTFAI Zoltán

[INTRODUCTION - Rare asymptomatic pleuropulmonary neoplasms can represent serious differencial diagnostic difficulties both for clinicans and pathologists. Immunohistochemical tests are essential tools for the diagnosis of soliter fibrotic tumor of the pleura. These tests are also of diagnostic and prognostic importance. CASE REPORT - The report summarizes the case of an asymptomatic 63 years old man. The patient was admitted to hospital with a parahilar infiltrate of the right lung. Based on this chest X-ray abnormality pulmonary malignancy was suspected. The patient was referred to surgical intervention and the diagnosis of was based on post-surgical histology. These fibrotic tumors have typical immunohistochemical features. Although the histomorphology of the tumor suggested the presence of a benign tumor the p53 positivity and focal CD34 positivity indicated the possibility of malignant transformation as well. The patient is alive 17 months after surgery and there is no relapse of the disease. CONCLUSION - Although histologically benign, soliter fibrotic tumors of the pleura may occasionally transform into malignant variants. Therefore complete surgical resection and longterm clinical and close radiological follow-up is recommended for these patients. Clinician can plan well ahead the frequency and time of the follow-up with the help of the prognostic factors of hystology.]

[FACTORS INFLUENCING ADOLESCENT BLOOD PRESSURE - THE DEBRECEN HYPERTENSION STUDY]

PÁLL Dénes, KATONA Éva, ZRÍNYI Miklós, ZATIK János, PARAGH György, FÜLESDI Béla

[INTRODUCTION - The aim of the study was to obtain epidemiological data on the blood pressure (BP) status of high school students and familiar, constitutional and lifestyle factors influencing their blood pressure. METHODS - After a 10 minutes rest, three repeated BP measurements were taken from the right upper arm, separated by 5 minute intervals. All measurements were obtained by a validated, automated, digital OMRON M4 device. A total sample of 10 194 high school students from Debrecen, included 5163 boys and 5031 girls, whose average age was 16.55±0.99 years. RESULTS - Boys had a significantly higher BP than girls (122.51±13.47/69.58±8.92 mmHg vs. 111.24±12.5/67.41±8.92 mmHg) (p<0.001). There was a positive correlation between weight and BP (rsyst =0.42, rdiast =0.286; p<0.001), height and BP (rsyst =0.326, rdiast =0.145; p<0.001), but not between the age and BP. Subjects whose father had hypertension differed significantly from controls’ BP (p<0.001). If the mother was considered being hypertensive only the diastolic BP differed. Subjects with low birth weight (<2500 grams) in the history had significantly greater systolic (p<0.002), but not diastolic BP than those weighting >2500 grams at birth. Subjects smoking, consuming alcohol, living a stressful life, eating salty foods, or doing regular workout did not differ in terms of both systolic and diastolic BP in our sample. CONCLUSIONS - Significant positive associations were found between BP and height and weight, with a stronger relationship to systolic BP. The males’ BP exceeded the females’ values, while those having hypertension in their family history or low birth weight had also higher BP.]

[Gene-expression profiles in adjuvant treatment of early breast cancer]

PAJKOS Gábor

[Breast cancer is a heterogeneous disease with different subtypes having a distinct biological, molecular, and clinical course. Assessments of standard clinical and pathological features have traditionally been used to determine the use of adjuvant systemic therapy in early-stage breast cancer; however, the ability to identify those who will benefi t from adjuvant chemotherapy remains a challenge, leading to over treatment of some patients. Risk stratifi cation of patients with early stage breast cancer may support adjuvant chemotherapy decision-making. This review details the development and validation of seven multi-gene classifi ers, each of which claims to provide useful prognostic and possibly predictive information for early stage breast cancer patients. A careful assessment is presented of each test’s analytical validity, clinical validity, and clinical utility, as well as the quality of evidence supporting its use.]

[The prevalence of therapy resistant hypertension]

FEJES Imola, ÁBRAHÁM György, LÉGRÁDY Péter

[In our country as well as around the world the most common chronic disease is the hypertension, and it is also an important risk factor causing disability and premature death. Within this, getting to know the true prevalence of therapy- resistant hypertension is important also from a public health perspective, since the prognosis of it is worse than that of those who reaches goal blood pressure range. It usually comes with hypertension mediated organ damages and higher (2- 2.5 folder) cardiovascular risk. It is prevalence in the literature is from 5% to 30%. The knowledge of the true prevalence depends on many factors, like: there are many different definitions of resistant hypertension, what is the main profile of the data collecting study site and what level of the health care system it works, or for example a questionnaire of a multicenter trial cannot be used totally in each country and study site.]

[Epidemiology of hypertension in Hungary]

SZEGEDI János, KÉKES Ede, SONKODI Sándor, KISS István

[The most important aspects of Hungarian hypertension epidemiology are demonstrated. The prevalence of hypertension is continuously increasing and in 2011 from the nearly 10 million population exceeded 3 million. Its occurrence rises in parallel with the increase in of systolic blood pressure and the progression of age, and exceeds 60% in those aged over 65 years. The average blood pressure is increasing in children and adolescents, and isolated systolic hypertension is often observed in those over 65-70 years. The situation is closely related to overweight in the young, while in elderly the atherosclerotic process results in low diastolic blood pressure. The prevalence is significantly different in some regions with the highest incidence in South-Transdanubia and North- Hungary. Overall, there is a higher incidence in women. Among known hypertensive patients, the ratio of men is greater till 40-45 years; thereafter, there will be an equilibration and in elderly women the incidence will be higher. It is interesting, that the morbidity and mortality have significantly increased in hypertension and diabetes since 2004, while the incidence of myocardial infarction and stroke has significantly decreased. As concerns organ damage, an increase in occurrence of left ventricular hypertrophy and microalbuminuria has been observed. Metabolic syndrome, diabetes mellitus and ischemic heart disease were the most frequent comorbidities.]

[The future in danger: a survey of the changes in the number of neurologists and a prognosis for 2010 in Hungary]

BERECZKI Dániel, CSIBA László, KOMOLY Sámuel, VÉCSEI László

[Lack of neurologists has become an obvious problem recently in Hungary, not only in small hospitals, but in major health care centers and also in university hospitals. With the current survey we set forth to estimate the number of board certified neurologists, and to evaluate the foreseeable changes in the next decade. In the beginning of 2010 there were 1310 physicians in Hungary with an official license to practice neurology. During 2009 neurological performance at least once during the year was claimed to the National Health Insurance Fund by 948 board certified neurologists. The number of those neurologists who are routinely involved in neurological patient care was estimated to be around 750. The lack of the young generation is characteristic for the age distribution of neurologists. In nine out of the 19 counties of Hungary the number of neurologists below the age of 35 is one or nil. In the ten-year period of 2000-2009 the annual mean number of new board certifications in neurology was 22. This number is much lower than that needed to replace those who get employed abroad and who leave the system for other reasons. The number of neurologists in the age range of 40-60 years will drop to 2/3 of the current number by 2020 even if emigration of neurologists will completely halt. If emigration will continue at the current rate and the number of those in neurological training will not increase considerably, then by 2020 only about 300 neurologists will have to cover neurological services throughout Hungary. As this number is insufficient for the task, and the tendency is clearly foreseeable, the health care government should urgently react to this situation to ensure an acceptable level of neurological services in the near future for the population of Hungary.]
