[The fundamental improvement of therapy in Parkinson's disease during the last 25 years also led to specific requirements in differential diagnosis of Parkinson-like diseases. It has become rapidly apparent that the idiopathic Parkinson's syndrome can be treated by a substitutional levodopa therapy very well in the beginning. Considering this fact especially in the case of a so-called "primary levodopa failure" a profound differential diagnosis is necessary. On the other hand an initially diagnosed Parkinson's disease can change its character and develops a widening if symptoms secondary to a reduced levodopa responsiveness. This process can be explained bz a spread of affected cerebral systems known as multy system atrophy (MSA). In former times the differentiation of Parkinson-like diseases could only be done by clinical examination and with regard to a missing levodopa responsiveness. In the last decade diagnostic availabilities became more and more. In addition to MRI and SPECT the 18-FDG- and 18-F-levodopa-PET-scan is very helpful in the cases mentioned above. The following presentation of differential diagnosis in Parkinson-like diseases outlines especially the possibilities of PET-screening.]

[Sumatriptan autoinjection in the acute treatment of migraine attack]

ERTSEY Csaba, JELENCSIK Ilona, ÁFRA Judit, BOZSIK György

[The authors report the results of the first Hungarian trial of 5-HT1 receptor agonist sumatriptan autoinjector in the acute treatment of migraine. During the treatment of 400 attacks in 67 patients a significant headache relief was reported in 41% after 30 minutes p. i. and 80.5% after 120 minutes p. i., respectively. In the same time frame complete dissolution of the headache was reported in 39.5% and 72%. The majority of the accompanying symptoms disappeared before the headache relief. Migraine recurrence was frequently noted (45.1% of all attacks). Slight side-effects were experienced in 36% of the attacks treated; in one case skin rash and in another one a temporary chest pain was reported. Using the autoinjector device did not pose serious problems to the patients.]

[Vasoreactivity changes of healthy volunteers investigated by transcranial doppler]

VALIKOVICS Atilla, OLÁH László, FÜLESDI Béla, MUNKÁCSY Csaba, CSIBA László

[Transcranial Doppler (TCD) was used to measure the effect of 1 g acetazolamide (Diamox, Lederle) on blood flow velocity in the middle cerebral artery of 50 healthy volunteers (aged 20-70 years). Parameters of blood flow, blood pressure, heart rate and blood gas values were determined before and after intravenous administration of Diamox. The reserve capacity was expressed as a percentage change of baseline values. The acetazolamide did not result in significant blood pressure and blood gas changes. The mean velocity of blood flow before Diamox administration was 59.8+14.4 cm/s. The velocity of flow significantly increased after acetazolamide, peaking after 10 minutes. The extent of reserve capacity was the greatest in the age group of 31-40 years and the smallest in the 61-70 years group. The reaction was longer lasting in age groups over 50 years. Significantly higher flow parameters and greater reserve capacity was found in women than in men at each measuring time point. The reserve capacity depended on age and gender.]

[Distant neuromuscular effect of locally injected botulinum toxin]

DIÓSZEGHY Péter, GLAUB Teodóra, MECHLER Ferenc

[Distant neuromuscular effect of locally infiltrated botulinum toxin was studied. The extensor digitorum communis muscle far from the place of injection was sampled with single-fiber EMG in patients treated for spasmodic torticollis. In 2 and 8–16 weeks after the infiltration the mean jitter values increased significantly compared to that of the results before the treatment. Extremely increased jitter values and blocks were found, too. The fiber density was also higher after the botulinum toxin infiltration. The electrophysiological changes may be a consequence of presynaptic blockade, the botulinum toxin induced terminal sprouting of motor axons and formation of new neuromuscular junctions. Parallel with the electrophysiological abnormalities no remote clinical effects were found. The single-fiber EMG proved to be a sensitive method to control the remote neuromuscular effect of botulinum toxin.]

[Schizophrenia-like psychotic episode in Multiple sclerosis]

SIMÓ Magdolna, RÓZSA Csilla, BODROGI László, TAKÁTS Annamária

[A case is presented of a twenty-year-old female with multiple sclerosis. In 1990 the patient had three exacerbations with cerebellar, optic and pyramidal symptoms. After a four-year period of remission she was hospitalized with acute schizophrenia-like psychosis. Acute psychosis is an uncommon manifestation of multiple sclerosis which may cause difficulties in differential diagnosis.]

[LADA type diabetes, celiac diasease, cerebellar ataxia and stiff person syndrome. A rare association of autoimmune disorders]

SOÓS Zsuzsanna, SALAMON Mónika, ERDEI Katalin, KASZÁS Nóra, FOLYOVICH András, SZŰCS Anna, BARCS Gábor, ARÁNYI Zsuzsanna, SKALICZKI József, VADASDI Károly, WINKLER Gábor

[Celiac disease - in its typical form - is a chronic immunemediated enteropathy with typical clinical symptoms that develops against gliadin content of cereal grains, and is often associated with other autoimmune diseases. In cases of atypical manifestation classic symptoms may be absent or mild, and extra-intestinal symptoms or associated syndromes dominate clinical picture. The authors present a longitudinal follow-up of such a case. A 63-years old woman was diagnosed with epilepsy at the age of 19, and with progressive limb ataxia at the age of 36, which was initially thought to be caused by cerebellar atrophy, later probably by stiff person syndrome. At the age 59, her diabetes mellitus manifested with type 2 diabetic phenotype, but based on GAD positivity later was reclassified as type 1 diabetes. Only the last check-up discovered the celiac disease, retrospectively explaining the entire disease course and neurological symptoms. By presenting this case, the authors would like to draw attention to the fact that one should think of the possibility of celiac disease when cerebellar ataxia, progressive neurological symptoms and diabetes are present at the same time. An early diagnosis may help to delay the progression of disease and help better treatment.]

[OVARIAN CHORIOCARCINOMA - A MOLECULAR PATHOLOGIC APPROACH TO DIFFERENTIAL DIAGNOSIS]

ERÉNYI Éva, SZIGETVÁRI Iván, ANDRIKOVICS Hajnalka, TORDAI Attila, URBÁN Márta, SIMON Károly

[INTRODUCTION - Gestational and non-gestational choriocarcinoma, the two types of choriocarcinoma with distinct aetiologies, cannot be differentiated by conventional histological or immunohistochemical methods. In certain cases the verification of the origin of the tumour by molecular biological techniques is essential for prognostic and therapeutic reasons. CASE REPORT - A 22-year-old woman presenting with acute abdominal pain was examined and operated on. During surgery a tumour was found in the right ovary. “Pure” choriocarcinoma was histologically diagnosed and gestational origin was supposed based on the distinct clinical features and histological picture. This was subsequently confirmed by molecular genetic testing. Parallel VNTR (variable number of tandem repeats) analysis by PCR of DNA from the tumour tissue and the patient's peripheral blood was performed. The pattern showed the presence of an allele presumed to be of paternal origin. (Blood sample from the father was not available.) One regimen of Vepesid, Cisplatina and Bleomycin was applied, and more than three years after the diagnosis the patient is free of disease. CONCLUSION - Multidisciplinary cooperation led to an accurate diagnosis and successful treatment. Non-radical surgery with the preservation of fertility followed by proper early chemotherapy provided excellent results.]

[CLINICAL ANALYSIS OF PATIENTS WITH PERIPHERAL FACIAL PALSY]

ILNICZKY Sándor

[symptoms. In two thirds of the cases the cause is unknown, this is called “idiopathic peripheral facial palsy or Bell’s palsy”, but several different diseases have to be considered in the differential diagnosis. In this paper we reviewed the case histories of 110 patients treated for “peripheral facial palsy” in the Department of Neurology, Semmelweis University, Budapest in a five year period, 2000-2004. We studied the age, gender distribution, seasonal occurance, comorbidities, sidedness, symptoms, circumstances of referral to the hospital, the initial diagnoses and therapeutic options. We also discuss the probable causes and consequences of diagnostic failures. Results: the proportion of males and females was equal. There was no considerable difference between sexes regarding agedistribution. Of the 110 patients 106 was diagnosed with idiopathic Bell’s palsy, three cases with otic herpes zoster and one patient with Lyme disease. In our material, peripheral facial palsy was significantly more frequent in the cold period of late autumn, winter, and early spring. Diabetes mellitus and hypertension were more frequent than in the general population. 74% of the patients were admitted within two days from the onset of the symptoms. In 37% preliminary diagnosis was unavailable. In 15% cerebrovascular insult was the first, incorrect diagnosis, the correct diagnosis of “Bell’s palsy” was provided only in 16%. The probable causes of diagnostic failures may be the misleading symptoms and accompanying conditions. We examined the different therapies applied and reviewed the literature in this topic. We conclude that intravenous corticosteroid treatment in the early stage of the disease is the therapy of choice.]

[The clinical pathology of prostatic carcinoma]

KISS Ferenc

[On the basis of the actual state of art, the main tasks of clinical pathologists in the diagnostics of prostatic carcinoma may be summarized as follows: Recognition and differential diagnosis of prostatic adenocarcinoma. Estimation of tumour prognosis by means of a reliable histological grading system and establishing the pathological stage. Checking the efficacy of (hormonal) treatment relying upon histological features. An increasing effort to a better understanding and diagnosis of premalignant changes (dysplasia, prostatic intraepithelial neoplasia). In favour of individual characterization of a tumour, one should utilize the attainable modern investigative methods.]

[The differential diagnosis of pulmonary tuberculosis]

BÖSZÖRMÉNI Miklós

[Since the number of tuberculous patients is constantly decreasing, the diagnosis of pulmonary tuberculosis is a new challenge for physicians. That produces a lifethreatening danger specially for old tuberculous patients. Primary infection – since the clinical tuber culosis of children practically disappeared in Hungary - can be established mostly on young people with general symptoms, who's tuberculin-reaction shows hyperergy. The specific etiology of pleurisy can be determined by the exclusion of other etiologies on young tuberculin-positive people, but a thoracoscopic biopsy may be needed. Tuberculous bronchadenitis is a rarity, but must be differentiated from sarcoidosis or malignant mediastinal lymph nodes. In infiltrative lung diseases, primary and se condary pneumonias (caused in first line by lung cancer) and pulmonary infarctions are much more frequent, than tbc. The most difficult is the differential diagnosis of disseminated pulmonary diseases. The author warns against the too early application of aggressive diagnostic methods (BAL and especially lung biopsy by thoracotomy). He emphasizes in these situations the advantages of an antituberculous treatment without diagnosis (especially in old patients). In coin lesions the very specific transthoracic needle biopsy should be preferated. The author refers to the new researches objecting the rapid detection of BK in the sputum of paucibacillary patients, but is meaning, that the indirect ways of diagnosis mentioned in this paper would be necessary for a long time.]
