[UNSOLVED THERAPY - COMPLEX TREATMENT OF BUERGER’S DISEASE]

SZOMJÁK Edit, DÉR Henrietta, KEREKES György, VERES Katalin, DEZSŐ Balázs, TAKÁCS István, TÓTH Judit, MÓZES Péter, SOLTÉSZ Pál

[INTRODUCTION - Buerger’s disease is a nonatherosclerotic, segmental, inflammatory, progressive obliterative disease of the blood vessels that most commonly affects the small and medium-sized arteries and also the veins of the lower limb. It is strongly associated with tobacco use. CASE REPORT - A 37-year-old heavy smoker forest worker presented with severe gangrenous changes on the fingers as the upper limb manifestations of Buerger’s disease, which required acral amputation. After complex medical treatment, pharmacological sympathectomy on the left side and surgical sympathectomy on the right side, bilateral conserving necrectomy, cessation of smoking and 2 cycles of cyclophosphamid, the patient's status significantly improved, his pain diminished and, although to a limited extent, he could use both hands. CONCLUSIONS - Buerger’s disease is a disorder with unclear aethiology and is difficult to diagnose. Despite of a good prognosis, a causal treatment is not yet possible, so any antithrombotic, haemorheological, vasodilator or immunosuppressive therapy that have been reported to have beneficial effect should be considered for treatment.]

[IMMUNE-MEDIATED NEUROLOGICAL DISORDERS]

CSÉPÁNY Tünde

[Multiple sclerosis, myasthenia gravis and chronic inflammatory neuropathies share the common feature of chronic course with potential development of disability due to the damage caused by immunological processes. Early detection and precise diagnosis is very important, because most patients respond well to proper immunomodulatory treatment. The diagnosis requires extensive knowledge of the disease and is based on the clinical symptoms recognised by the GP, as well as on complex assessment of the results of special neurophysiological, radiological and laboratory examinations. The present paper reviews the major immune-mediated neurological disorders and discusses their targeted immunological treatment.]

[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.]

[New chapter in visual evoked potential studies - Clinical application of the multifocal vep method ]

JANÁKY Márta, PÁLFFY Andrea, BENEDEK Krisztina, BENEDEK György

[The multifocal visual evoked potentials are the evoked responses over the visual cortex in response to the stimulation of circumscribed small areas in the central 30 degree region of the retina. The recording of multifocal visual evoked potentials was made possible by the computer algorhythm elaborated by Sutter in 1991. Multifocal electroretinograpy, developed upon the same theoretical principles, is already an routine clinical examination method for the topographic analysis of functional damages in the central part of the retina and for the differential diagnostics in neuro-ophthalmology. The multifocal visual evoked potential, however, has not been introduced into the clinical practice, although it displays the function of ganglion cells in a given region of the retina in a more detailed way than the sensitivity threshold in the perimetry. This examination makes the objective verification of defects possible in the visual pathway, too. In our department the recording of multifocal visual evoked potentials was started in 2002. In this paper we present the basics of this method and also deal with the problems concerning its application and its status in the history of visual evoked potentials.]

[Dysexecutive syndromes]

SZIRMAI Imre

[Executive function is a higher order cognitive capacity that involves memory, perception and performance of complex tasks. Disorders of the executive functions are sign of lesions in the praefrontal cortex, involving the praefrontal-striatal-thalamic networks and the parietal association areas. According to signs and localization, five basic praefrontal syndromes are recognised. 1. Damage in posterior dorsolateral praefrontal cortex and subcortical nuclei causes the dorsolateral syndrome with impaired decision making, working memory and planning. 2. The ventromedial-orbitofrontal syndrome: if lesion spares the basal forebrain, memory can be preserved, but poor social decision making developes. 3. The dorsomedial syndrome consists of attention disorder, akinesia, mutism and apathy. 4. The bilateral ventrolateral praefrontal regions serve perception of self and environment. 5. The ventral lateral (verbalizer) area of the dominant hemisphere coordinates language. Executive impairments can be found in cerebrovascular, Parkinson's and other diseases of basal ganglia, and in frontotemporal lobar degeneration. The dorsolateral syndrome can be examined by the use of Wisconsin card sorting test, self ordered pointing task and the delayed response task. Praefrontal-basal function can be assessed by Gambling-, Faux Pas-, and Emotion identification tasks. Conclusions: 1. A dysexecutive syndrome does not fulfil the criteria of dementia. 2. A "frontal syndrome" is an indefinite eponym. Focal lesions in prefrontal systems lead to localization- specific symptoms, which can be defined by psychometric tests. 3. In neurological diseases associated with multifocal damage of the brain neuropsychologic tests may help to determine strategical lesions, which are responsible for the actual syndromes.]

[RIFAXIMIN IN THE TREATMENT OF HEPATIC ENCEPHALOPATHY - A MULTICENTRIC STUDY]

SZALAY Ferenc, TELEGDY László, SZELI Dóra, CSÁK Tímea, FOLHOFFER Anikó, HORVÁTH Andrea, ABONYI Margit, SZABÓ Olga, RÉDEI Csaba, NEMESÁNSZKY Elemér

[INTRODUCTION - Hepatic encephalopathy is a well-known neuropsychiatric syndrome occurring in patients with either acute or chronic liver diseases. Rifaximin, a non-absorbable antibiotic is accepted for the treatment of hepatic encehalopathy. Our aim was to investigate the efficacy and the safety of rifaximin in cirrhotic patients with hepatic encephalopathy in Hungary. PATIENTS AND METHODS - 49 patients (25 male and 24 female) with hepatic encephalopathy stage I., II. and III. were involved into the study. Patients were treated with rifaximin for seven days. The daily dose was 3x400 mg in tablets. The severity of hepatic encephalopathy was characterised by hepatic encephalopathy index (HEi) calculated as a score of five parameters; mental state, asterixis, ammonia level, number connection test and critical flicker frequency. Pretreatment and postreatment HEi were compared. RESULTS - The study was completed in 46 patients. The treatment was suspended in 2 patients who died in liver failure and in one because of oesophageal variceal bleeding. The plasma ammonia level decreased from 103.7 ± 46.4 μmol/L to 67.7 ± 32.3 μmol/L (p=0,007) during the treatment. The hepatic encephalopathy index improved in 39 (85%) patients, worsened in 4 (9%) and no change was observed in 3 cases (6%). Improvement was observed in patients both with Child B and Child C stages. Loose stool in two patients and nausea in one patient were the only registered side effects. No severe adverse event related to the study medication was observed. CONCLUSIONS - Rifaximin is an effective and safe medicine for the treatment of hepatic encephalopathy.]
