[Radiology of pancreas: review from the last year - Gastro Update 2007]


[PURPOSE - To demonstrate the recent results in radiological diagnostics of pancreas, and the actual place of the imaging and interventional methods. METHOD - Systematic review of the most recent articles from the last year in the following subjects: acute, chronic and autoimmune pancreatitis, pancreatic cancer and other tumors, PET and special imaging problems in pancreas transplantation. RESULTS - Annually, experience in pancreatic diagnostical methods are accumulating rapidly. Therefore, there is a continuous change in the examination algorithm with new diagnostic and therapeutic modalities making their way into the daily routine. Some of the algorithms become obsolete within a few years and their further application is considered mismanagement. Some other methods become obligatory steps in the diagnostics. These are the reasons why up-to-date knowledge of the literature is mandatory.]

[Role of contrast enhanced ultrasound in clinical practice]


[Ultrasound contrast agents consist of micro bubbles which can be visualized during their short intravascular and parenchymal transit time. An US system with special software, a small amount of intravenous contrast agent and a skilled operator is necessary to produce a successful study. This method can also be introduced into the clinical practice in our country. Careful indications and well performed studies can reduce the number of unnecessary CT and MR studies and biopsies. Contrast enhanced US has special clinical significance in the detection and characterization of focal liver masses, monitoring drug and local treatment effects of different abdominal tumors and in the case of injury of abdominal parenchymal organs.]

[Evaluation of cystic renal masses with MDCT]


[Modern CT and MRI scanners can give an exact and rapid diagnosis in the case of most cystic renal masses. Dilemma in their diagnosis is whether or not the changes need surgical intervention. The question of follow-up is decided with the use of the Bosniak classification. To characterize the cystic changes excellent quality, multiphasic MDCT examination is necessary with the following parameters: 80-120 mls. of non-ionic iodinated intravenous contrast material given with an injector at 3 ml/sec flow-rate with saline flush technique, unenhanced and post-contrast scans obtained at 35 and 70 seconds, with more scans at 120-300 seconds, as deemed necessary. A collimation of 16x1.5 mm with an overlap of 50% should be aimed for. Through the primary data we perform a reconstruction of 2 mm, with an option to create volume-rendered image sin the post-processing phase, as necessary. With the help of this CT protocol we can measure the different criterions of Bosniak classification in the cystic masses like minimal, smooth or irregular wall thickening, with or without enhancement. We can recognize hairline thin or thickened septa, fine or irregular (thick or nodular) calcifications, solid component with or without contrast enhancement. Using these criteria each cystic mass can be assigned to a Bosniak cystic category (I, II, IIF, III and IV)]

[High resolution sonography for the examination of peripheral nerves]


[High-frequency sonography is an important method for the imaging of the peripheral nerves, even though it is rarely used. For the examination of superficially located nerves, currently available transducers with frequencies between 12-17 MHz offer a better axial resolution than even MRI. Sonography is superior to MRI especially for the examination of nerves of the upper extremity. Main indications for the sonography of the nerves are entrapment syndromes, traumatic injuries of the nerves, tumors, polyneuropathies and sonographically-guided interventions. The sensitivity of sonography and electrophysiology in the diagnosis of carpal tunnel syndrome and cubital tunnel syndrome are comparable. The combination of ultrasonography with electrophysiological studies increases the diagnostic yield in carpal and cubital tunnel syndromes. Sonography provides information for planning of peripheral nerve surgery and is helpful in evaluating postoperative complications. In selected cases, sonography can detect nerve lesions that require operative therapy earlier than electrophysiology. With technical enhancements, highfrequency ultrasonography is gaining increasing importance in the routine diagnostics of peripheral nerves lesions.]

[The connection between the socioeconomic status and stroke in Budapest]


[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. ]

[The Veszprém model, alias a different approach of psychiatric care]


[This study describes an integration of a county-level psychiatric care unit with two elements of primary social care, namely the community psychiatric care and the daycare for psychiatric patients via mediation of a specific foundation. Adequate trainings make the connection and dual employment possible in the presented system. On the health care side development is characterized by extended psychiatric care with effective psychosocial interventions. Adding specialized group psychotherapies and sociotherapies to the activity of the social care also brought a quality change, extension of which provided self-help and the consumers' applicability as therapy leaders in sociotherapy group. Based on our ten years of practice we may declare that recovery-based psychiatric rehabilitation can be realized more effectively in this community-based biopsychosocial model of care. ]

[Cholesterol-lowering is not the Holy Grail, but neither is the work of the devil]


[Cholesterol-lowering statins are the most tested medications in respect of the effects and side-effects. Based on these, we can safely claim that most of the negative opinions about cholesterol-lowering are not realistic. It is not a panacea, but it is proven that around a 30% of cardio- and cerebrovascular risk reducation can be achieved by their regular taking, while the incidence of side effects and risks are at least one order of magnitude lower in each patient groups. For cholesterol, there is no “normal” lab threshold or low level, only “target values”, since the mean value in the general population is high in regard of atherosclerosis (the values measured at birth and among natural people can be considered normal). Let us appreciate the cholesterol- lowering medications because we do not have a large armamentarium!]
