[INTRODUCTION - Haemangioma is the most common type of benign hepatic tumors. Haemangiomas are usually asymptomatic, except for those that exceed five centimeters in size and are called “giant” haemangiomas. Malignant transformation has not been noted and therefore only regular follow-up is recommended for smaller haemangiomas. Surgical intervention becomes necessary only if symptoms or complications occur. Nevertheless, atypical presentation can cause a significant differential diagnostic problem. CASE REPORT - The authors report the case of a 51-year old woman with a focal hepatic abnormality diagnosed during a routine abdominal ultrasound examination. Results of the subsequent computed tomography scan suggested a multiple hepatocellular carcinoma based on the morphological appearance. Following oncology consultation, she was admitted to our department for liver biopsy. Histology did not reveal any malignancy. This result together with the lack of symptoms and complaints and the normal laboratory test results shifted the likely diagnosis towards a benign haemangioma. Blood-pool scintigraphy confirmed this diagnosis. CONCLUSIONS - Haemangiomas are benign hepatic tumors. They are often diagnosed accidentally, by routine abdominal ultrasound examination. If an abdominal ultrasound raises suspicion of haemangioma, abdominal MRI scan or blood-pool scintigraphy is recommended to be performed in order to exclude malignancy for lesion sizes of <2 cm or >2 cm, respectively. The reported case is considered important because of the differential diagnostic problems the large size and the atypical presentation of the given haemangioma imposed. Ultrasound-guided liver biopsy via fine-needle aspiration has previously been contraindicated. This invasive procedure can be performed in patients with focal hepatic pathology if diagnosis cannot be established by non-invasive tests, especially if malignancy is suspected. It can be performed conditional on the localization of the tumor, the patient’s general condition, the laboratory results, and if there is a therapeutic consequence of the biopsy results.]

[Treatment of acute pancreatitis, with special regard to pharmaceutical therapy]

DÖBRÖNTE Zoltán

[Treatment of acute pancreatitis is mainly supportive, including the correction of any factors causing or sustaining the disease process, efforts to limit complications, as well as treatment of complications. Pharmaceutical efforts to influence the pathophysiological events with protease inhibitors or by influencing the release of the pro-inflammatory cytokine cascade did not prove to be effective, so there is no known effective and specific drug therapy for clinical use. Adequate pain control is an important component of pharmaceutical management, and - although yet controversial - early antibiotic prophylaxis and effective antimicrobial treatment of the inflammatory complications (infected necrosis or fluid collection, SIRS, sepsis) have probably a determining role in the outcome of severe necrotizing pancreatitis. Carbapenems proved to be the most potent antibiotics. For the prevention of the not infrequent fungal superinfection in acute pancreatitis, early administration of fluconasole can also decrease mortality. Surgery is indicated in the first stage of infected necrosis and infected pancreatic and peripancreatic fluid collections. In certain patients with a high operative risk, endoscopic or percutaneous drainage with lavage can also be worth trying. Optimal conditions for the treatment of severe necrotizing pancreatitis, as well as adequate management of multiple organ failure can only be warranted at an intensive care unit. In the chemoprevention of pancreatitis complicating endoscopic retrograde cholangiopancreatography (ERCP), non-steroidal anti-inflammatory drugs promise a new therapeutic option. There are insufficient data about the beneficial effects of the protease inhibitor ulinastatin, and results with nitroglycerin are contradictory.]

[Sudden cardiac death in athletes - cardiac electrophysiology point of view]

VARRÓ András

[Sudden cardiac death of athletes is very rare (1/50 000 to 1/100 000 annually) but it is still 2 to 4 times more frequent than that of the agematched normal population. In addition, it attracts peculiar media attention. Sudden cardiac death in athletes is supposed to not primarily have an ischemic origin but most likely relates to repolarization abnormalities. These may be caused by several independent and/or dependent factors such as benign cardiac hypertrophy developing normally in athletes (athlete’s heart), hypertrophic cardiomyopathy, increased sympathetic activity, genetic defects, seemingly harmless drugs, doping agents, food, and dietary supplements. These factors together can increase inhomogeneities in myocardial repolarization (“substrate”). In this case, an otherwise harmless extrasystole (“trigger”) occurring with unlucky timing may - although very seldomly - elicit fatal arrhythmias. Thus, effective prevention of sudden cardiac death may include new types of cost-effective cardiac electrophysiological screening methods (ECG or echocardiography) and, in case of a high level of suspicion, more costly genetic tests can be considered.]

[Practical considerations in the state-of-the-art management of ankylosing spondylitis]

SZÁNTÓ Sándor, SZEKANECZ Zoltán

[Ankylosing spondylitis is an inflammatory rheumatic disease characterized by inflammation of the spinal and sacroiliacal joints, which causes chronic back pain and ultimately spinal stiffness, impaired motility, and deformity. Until the last decade, treatment mainly consisted of a combination of physical therapy and non-steroidal anti-inflammatory drugs, but recently tumor necrosis factor-α inhibitors revolutionized therapy and improved clinical outcomes. Tumor necrosis factor-α inhibitors effectively control inflammation of the sacroiliacal and spinal joints as shown by improved signs symptoms, and functions, magnetic resonance imaging findings, and reduction of acute phase reactants. Whether these drugs are capable of preventing radiographic progression and structural damage has, however, to be clarified in future studies. This review aims to highlight recent progress in the treatment of ankylosing spondylitis, and to provide recommendations for its management.]

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.

[A CASE OF PRIMARY HEPATIC AMYLOIDOSIS PRESENTING WITH GASTRIC BLEEDING]

STOGICZA Ágnes, GRABER Hedvig, SKALICZKI József, NÁDOR Katalin, MAGYAR Tamás

[INTRODUCTION - Amyloidosis - at an early stage - has no typical clinical findings, but severe weight loss, hepatomegaly and elevated serum alkaline phosphatase level can be clues to the diagnosis. CASE REPORT - We report a 66-year-old woman presenting at our unit with massive gastrointestinal bleeding. Gastroscopy was performed and a haemorragic ulcer was found. Before admission she had lost 20 kg-s in 6 months. The patient had hepatomegaly and markedly elevated serum alkaline phosphatase level. These findings suggested the presence of malignancy, but ultrasound, CT and MR examinations did not support this hypothesis. After liver biopsy the diagnosis of amyloidosis was proven. She had rapid downhill clinical course of gastric bleeding from an ulcer resulting in death. CONCLUSIONS - So far, no specific treatment exists for amyloidosis, but there have been promising results reported about liver transplantation and autologous stem-cell transplantation.]

[Selective ultrastructural vulnerability in the cuprizone-induced experimental demyelination]

ÁCS Péter, KOMOLY Sámuel

[Background and purpose - It has been reported that multiple sclerosis has four different neuropathological subtypes, and two of them (type III and IV) are characterized by primary oligodendrocyte loss. However, the exact pathomechanism that lead to oligodendrocyte apoptosis in human demyelinating diseases is still elusive. The copper chelator cuprizone induces primary oligodendrocyte apoptosis and consequent demyelination in well defined areas of the mouse brain. Nevertheless, the precise subcellular events that result in oligodendrocyte cell death in the cuprizone model are still unknown. We aimed to study the ultrastructural alterations that might induce oligodendrocyte apoptosis in the cuprizone experimental demyelination model. Methods - C57BL/6 mice were given cuprizone for two, 21 and 35 days to induce demyelination to investigate early pathological events, and different stages of demyelination. In addition, mice were given cuprizone for 35 days and were allowed to recover for two or 14 days to study early and late remyelination. After the cuprizone treatment, mice were sacrificed and the corpus callosum, the superior cerebellar peduncle, the optic nerve and the sciatic nerve were studied by electron microscopy. Results - The ultrastructural analysis revealed that cuprizone induced oligodendrocyte apoptosis is accompanied by the formation of giant mitochondria in the affected cells in the corpus callosum and in the superior cerebellar peduncle. Apoptosis of the myelin producing cells was present through the whole cuprizone challenge. Severe demyelination occurred after three weeks of cuprizone administration associated with massive macrophage infiltration and astrocytosis of the demyelinated areas. Axons and neurons remained unaffected. Conclusion - The formation of giant mitochondria in myelin producing oligodendrocytes is the first pathological sign in the cuprizone experimental demyelination. Mitochondrium pathology in the cuprizone challenge might serve as a useful model to study the pathomechanism of multiple sclerosis subtypes (III and IV) characterized by primary oligodendrocyte degeneration.]

[Isolated gallbladder rupture following blunt abdominal trauma]

PÉTER Lívia

[INTRODUCTION - Gallbladder injuries following blunt abdominal trauma occur rarely and are usually associated with damage to other abdominal organs. Isolated rupture of the gallbladder is extremely rare. CASE REPORT - A 42-year old intoxicated male patient suffered a blunt abdominal trauma 4 days before the admission. The physical examination was of normal and no specific laboratory values were found. Ultrasound examination demonstrated the gallbladder with hyperechoic thickened wall and inhomogenous content. Beside of the gallbladder fluid collection was detected with irregular margins. To prove the diagnosis of gallbladder injury computed tomography was carried out. Break of the gallbladder wall and hight density lumen content, corresponding to blood was detected. Around the gallbladder an irregular fluid collection was seen, which reached the level of the transverse section of the mesocolon. Computed tomography excluded traumatic lesion of other parenchimal abdominal organs. Surgery confirmed the radiological diagnosis. CONCLUSION - The patient with isolated gallbladder injury had a multiphasic clinical course. Sometimes the diagnosis has to be established at a relatively asymptomatic stage. The basic methods of the diagnostics are the ultrasound examination and computed tomography.]
