[A case of diffuse primary leptomeningeal gliomatosis, complicated by ischemic myelopathy is presented. Symptoms developed acutely in a 13 year-old girl with neurofibromatosis type 1, previously manifesting only in kyphoscoliosis and typical melanotic skin dots. Autopsy revealed extensive involvement of the cerebrospinal leptomeninges by a low-grade (pilocytic) astrocytoma, with secondary thrombosis of the posterior spinal arteries. There was no evidence of parenchymal involvement by the tumour. Histopathologic features of primary glial neoplasms of the leptomeninges and major traits of their symptomatologic correlates are discussed. With regard to problems of diagnostic access to nervous system neoplasms associated with phacomatoses, hazards of prognostic evaluation are envisaged.]

[Somatic defects and pain manifested at adults' drawings of a man]

GRYNAEUS Tamás

[The outhor observed that “draw-a-man tests” of mentally retarded or demented adult patients may truly reflect their somatic defects or painful disorders. Drawings of mentally intact patients could also exhibit their somatic illness if it causes pain or the compensating mechanisms are insufficient. A brief discussion is given on the possible mechanisms, in connection with the body-schema.]

[The effect os levodopa in Parkinson's disease ]

MECHLER Ferenc, DIÓSZEGHY Péter, GLAUB Theodóra, HIDASI Eszter, JOSE Rosa

[The effect of carbidopa/levodopa on clinical signs and laboratory data was studied in 21 patients with Parkinson's disease during a follow-up period of 7-12 months. The Columbia and Webster scales were used for analysis. The improvement was significant already in the first weeks of the treatment. The drug did not influence the laboratory data and the side effects were found to be insignificant. The changes due to the drug were analysed by electrophysiological methods. Certain peak amplitudes and the area of visually evoked responses increased significantly during the treatment suggesting facilitation in the function of visual pathways. On stimulating the motor system by transcranial and spinal magnetic stimulation, the motor latencies and the duration of silent period showed normalization. ]

[The prognostic relevance of apoptosis in medulloblastoma]

SCHUBERT EO Thomas, CERVOS-NAVARRO Jorge

[Apoptosis is known to be a phenomenon of prognostic significance in certain neoplasms. Several previous studies have indicated that the prognosis of desmoplastic medulloblastoma is better than that of classical medulloblastoma. We studied 5 desmoplastic and 5 classical medulloblastomas by in situ end labelling of DNA strand breaks to see whether there is any difference in amount or pattern of apoptosis in these subtypes, correlating to the different prognostic behaviour. We found no significant difference neither in amount nor in pattern of apoptosis between the two subtypes. Our results indicate that apoptosis may not be a relevant variable in the prognosis of medulloblastoma.]

[Thrombolytic therapy in acute ischemic stroke (preliminary report)]

HAFFNER Zsolt, HORVÁTH Erzsébet, HORVÁTH Éva, PAPP Gabriella, EGERVÁRI Ágnes, LIPÓTH Sarolta, CSÁNYI Attila, TUKA Andrea

[Intravenous stretiokinase infusion therapy was performed on four patients in acute occulsive cerebrovascular disease (hemorrhage was rxcluded by CT scan). The thrombolytic therapy was started not later than six hours after the onset of the first symptoms. Kabikinase (1 250 000 IU) was administered in intravenous infudion during two hours. After thrombolysis no prolonged anticoagulant therapy was applied. Improvement of the neurological symptoms was impressive and convincing: in two cases immadiate. Ino one case we could be observed during the treatment (2 hours) nor after it. The possibility of thromolytic therapy in acute occulsiv stroke should be take into consideration. So far as we are aware this is the first time that thromolysis is occulsive stroke according to a protocol like this has been used in Hungary.]

Fatal outcome of cervical myelopathy caused by fibrocartilaginous embolism. Rare cause of spinal vascular damage

FOLYOVICH András, HAVAS László, VADÁSZ Gizella, FEHÉR Ágnes, VADASDI Károly, SZABÓ Zsolt, TÓTH Kornélia, BÉRES-MOLNÁR Anna Katlin, TOLDI Gergely

Fibrocartilaginous embolism is a rare cause of ischemic myelopathy. Authors report a case of a 39-year-old woman with progressive tetraparesis and severe autonomic dysfunction. Despite of the detailed examinations, the definite diagnosis was verified by autopsy. The patient was admitted because of progressive pain and numbness of the upper extremities and tetraparesis. Hypotonic muscles of the lower extremities with mild tetraparesis were observed. Magnetic resonance imaging showed an intramedullary lesion at the level of the cervical V-VII vertebral. Patient’s tetraparesis worsened gradually to plegia with urinary retention. Expansive, rapidly progressing multiple decubiti developed, which were resistant to therapy. In spite of the complex therapy, the patient died. No internal disease was found to explain the death by autopsy. Multiple subacute infarctions of the cervical myelon (involving the lateral columns as well) in the territory of the anterior spinal artery were verified by neuropathological examination. The occluded vessels were filled by a material containing cartilaginous cells, while signs of atherosclerosis or thrombosis were not present. Cartilaginous embolism of spinal arteries was diagnosed.

[NEUROFIBROMATOSIS, MALIGNANT MELANOMA AND HYPERTHYREOIDISM IN A HCV POSITIVE PATIENT]

FOLHOFFER Anikó, HORVÁTH Andrea, CSÁK Tímea, NÉBENFÜHRER László, TELKES Márta, IVÁNYI András, SZALAY Ferenc

[INTRODUCTION - Similar occirrence of neurofibromatosis and malignant melanoma is rare. We report a patient with neurofibromatosis, cutaneous melanoma, hyperthyreoidism and HCV positivity. CASE REPORT - A 43-year-old woman has been under care for neurofibromatosis for 16 years when she presented with increased serum ?- glutamyltransferase, alkaline phosphatase activity and anti-HCV antibody positivity at regular checkup. A pigmented lesion removed from her back histologically proved to be cutan melanoma. Interferon treatment was applied. She lost 8 kilograms in half a year which was caused not by the tumor progression, but hyperthyreoidism. A rapid clinical and laboratory improvement was observed for thyreostatic treatment and she regained her bodyweight. One year later she presented with a cough caused by pulmonary tumor. The tumor was surgically removed and histologically diagnosed as metastasis of melanoma. Cytostatic treatment was applied and she became asymptomatic. Four years after the diagnosis of melanoma she died of apoplexy. During the autopsy there was no sign of either melanoma or liver disease. CONCLUSIONS - The careful investigation of skin should be emphasised even in case of long established neurofibromatosis. The presented case shows an association of malignant melanoma and neurofibromatosis. In the background of loss of bodyweight even in a patient with history of malignant disease other causes should also be searched such as hyperthyreoidism especially during interferon therapy.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.
