Lege Artis Medicinae - 1992;2(02)

[Immunologic reactions and their consequences are analyzed and discussed after implantation of merthiolate-banked, deep-frozen and decalcified allogenic bone. Radiographic and microscopic characteristics of consecutive immunologic changes were studied in animal experiments. Among all materials tested, deep-frozen grafts produced the most marked immunologic reaction together with bone resorption and the highest incidence of non-union. No immunologic reaction was observed after merthiolate-preservation; however, this technique evidence of microscopic foreign-body reaction. Transplantation of decalcified allogenic grafts produced only a mild response. Autologous transplants acted as controls. The authors conclude that clinical results can only be improved by optimal selection, based on experimental results, from among the available techniques.]

[New methods of plastic surgery for breast reconstruction]


[The treatment and plastic surgical reconstruction of breast tumour patients raise contradictions and unsolved problems. The approach of breast tumour surgery has been changed recently. New evidence shows that in terms of survival, free from distant disease there is no significant difference between lumpectomy and radical mastectomy. Thus breast-conserving operations as a replacement for radical mastectomy have been spreading. The most characteristic features of these operation are: the horizontal incision, the conservation of the pectoral muscles and the whole or partial preservation of glandular tissues. The quality and quantity of available tissues for the breast reconstruction have changed as, the methods of plastic surgical operations has been adopted. New methods for breast reconstruction such as muscle and musculocutaneous flaps, free flaps, different breast implants, and skin expanders have become more and more preferred. For nipple and areola reconstruction local flaps, skin grafts, external prostheses and tattoo are widely used. Nowadays the most important point of view in there the construction of the breast are accurate symmetry, aesthetic breast form and harmony of the whole body. ]

[Results in the sclerotherapy of varicocele]


[Testicular varicocele which is curable by surgical or transcatheteric methods is one of the most common causes of male infertility. In this study the success of the interventional radiological method was evaluated. Internal spermatic vein phlebographies were performed in the case of left sided varicocele. Before intervention the anamnesis, inspection, palpation, sonography, colour Doppler sonography and phlebography was evaluated and in a part of the cases spermiogramm too. Follow up examinations were performed at 3, 6 and 12 months after the sclerotherapy and the 1.5-4.5 years then later. The internal spermatic vein was succesfully occluded in 2/3 of the patients in the distal third, in 1/3 in the middle or in the upper third. Complications occurred in 10 cases as intima lesions without any consequencies and in 4 patients as scrotal thromboph lebitis. At the follow up examinations very good regression was demonstrated. Persistence or recurrence occured in 5.7% of cases. The spermiogramm usually got back to normal or showed an improvement and we registered 8 pregnancies from 23 formerly infertile marriages. The interventional radiological method is simpler, cheaper, requires shorter time and inpatient period, decreases sick-allowance, and the success rate reaches the level of the surgical method. The joint evaluation of the real time and the colour Doppler ultrasound is a very sensitive method in the interpretation of the results of the treatment. In our opinion sclerotherapy with Varicocid is the method of choice in the treatment of the varicocele. ]

[Mapping of EEG in neurological disorders]


[Mapping is a new way to convey the information of the mathematical analysis of the EEG in an immediately understandable form. In this article, the history of EEG mapping is surveyed. Sixteen channel EEG mapping system was programmed on an IBM-AT personal computer which constructs absolute and relative power spectra topograms on the scalp. Hemispheric asymmetry and long term changes of absolute and relative power estimates were calculated by statistical methods (Wilcoxon and Student t-test). In comparison traditional reading of the EEG the mapping has the following advantages: 1. it uses exact procedures instead of qualitative estimation; 2. in can detect minimal cortical damages; 3. it has the ability to store data for later comparison: the power ratios in selected frequency ranges proved to be a reliable indicator of post-ischemic restitution of EEG; 4. it can evaluate of event related reactions of bioelectric signals in higher resolution. EEG topography provides early information regarding the severity of ischemic lesions in the acute stage of stroke before to the CT scan can visualize the tissue hypodensity. In cases of permanent epileptic waves, the mapping visualizes the local power maxima of dominant frequency ranges and detects the post-ic talimpairment of cortical fields of epileptic foci. Probability significance mapping has reinstated the diagnostic value of EEG by the applica tion of the neuroimaging techniques.]

[Bidirectional Doppler investigation of the internal carotid artery]


[The blood-flow velocity in carodit arteries was measured with a bidirectional CW Kranz bühler 761 Doppler instrument. These investigations were supplemented with special compression tests. 60 investigations were performed to study the blood-flow in the supraorbital and supra trochlear arteries, while compressing the superficial temporal, the facial and the common carotid arteries. The results were compared with 30 regularly performed angiographies. Conclusions: the sensivity of this method is 80%, the specificity is 85%, its positive and negative predictive values are 76% and 87% respectively. Therefore this method is suggested for screening the internal carotid artery. ]

[Ultrasound examination of the knee]


[The knee is frequently injured. In addition to the phisical examination imaging methods are very important in determining the diagnosis of the disorders. Ultrasound method is useful in revealing the injuries of the soft tissues of the knee. The authors examined 350 patients with an Acuson 128 ultrasound machine, using 5 and 7 MHz linear transducer in standard positions. They analized the pathological disorders of the knee joint. They consider the examination of network of the band important. Sonography has a significant role in the diagnosis of knee disorders. That can replace more expensive or invasive examination methods.]

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

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

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.

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

[The importance of patient reported outcome measures in Pompe disease]

MOLNÁR Mária Judit, MOLNÁR Viktor, LÁSZLÓ Izabella, SZEGEDI Márta, VÁRHEGYI Vera, GROSZ Zoltán

[In recent decades it has become increasingly important to involve patients in their diagnostic and treatment process to improve treatment outcomes and optimize compliance. By their involvement, patients can become active participants in therapeutic developments and their observations can be utilized in determining the unmet needs and priorities in clinical research. This is especially true in rare diseases such as Pompe disease. Pompe disease is a genetically determined lysosomal storage disease featuring severe limb-girdle and axial muscle weakness accompanied with respiratory insufficiency, in which enzyme replacement therapy (ERT) now has been available for 15 years. In our present study, patient reported outcome measures (PROMs) for individuals affected with Pompe disease were developed which included questionnaires assessing general quality of life (EuroQoL, EQ-5D, SF36), daily activities and motor performance (Fatigue Severity Score, R-PAct-Scale, Rotterdam and Bartel disability scale). Data were collected for three subsequent years. The PROM questionnaires were a good complement to the physician-recorded condition assessment, and on certain aspects only PROMs provided information (e.g. fatigue in excess of patients’ objective muscle weakness; deteriorating social activities despite stagnant physical abilities; significant individual differences in certain domains). The psychological effects of disease burden were also reflected in PROMs. In addition to medical examination and certain endpoints monitored by physicians, patient perspectives need to be taken into account when assessing the effectiveness of new, innovative treatments. With involvement of patients, information can be obtained that might remain uncovered during regular medical visits, although it is essential in determining the directions and priorities of clinical research. For all orphan medicines we emphasize to include patients in a compulsory manner to obtain general and disease-specific multidimensional outcome measures and use them as a quality indicator to monitor treatment effectiveness.]

A new method to determine the optimal orientation of Slim Modiolar cochlear implant electrode array insertion

HORVÁTH Bence, PERÉNYI Ádám, MOLNÁR Fiona Anna, CSANÁDY Miklós, KISS József Géza, ROVÓ László

Our goal was to determine the optimal orientation of insertion of the Slim Modiolar electrode and develop an easy-to-use method to aid implantation surgery. In some instances, the electrode arrays cannot be inserted in their full length. This can lead to buckling, interscalar dislocation or tip fold-over. In our opinion, one of the possible reasons of tip fold-over is unfavourable orientation of the electrode array. Our goal was to determine the optimal orientation of the Slim Modiolar electrode array relative to clear surgical landmarks and present our method in one specified case. For the measurement, we used the preoperative CT scan of one of our cochlear implant patients. These images were processed by an open source and free image visualization software: 3D Slicer. In the first step we marked the tip of the incus short process and then created the cochlear view. On this view we drew two straight lines: the first line represented the insertion guide of the cochlear implant and the second line was the orientation marker (winglet). We determined the angle enclosed by winglet and the line between the tip of the incus short process and the cross-section of previously created two lines. For the calculation we used a self-made python code. The result of our algorithm for the angle was 46.6055°. To validate this result, we segmented, from the CT scan, the auditory ossicles and the membranaceous labyrinth. From this segmentation we generated a 3D reconstruction. On the 3D view, we can see the position of the previous lines relative to the anatomical structures. After this we rotated the 3D model together with the lines so that the insertion guide forms a dot. In this view, the angle was measured with ImageJ and the result was 46.599°. We found that our method is easy, fast, and time-efficient. The surgery can be planned individually for each patient, based on their routine preoperative CT scan of the temporal bone, and the implantation procedure can be made safer. In the future we plan to use this method for all cochlear implantation surgeries, where the Slim Modiolar electrode is used.

[Treatment and new evidences in neuromyelitis optica spectrum disorder ]


[Treatment and new evidences in neuromyelitis optica spectrum disorder Illés Zs, MD, PhD Ideggyogy Sz 2021;74(9–10):309–321. Neuromyelitis optica spectrum disorder (NMOSD) is associated with antibodies against AQP4 in about 80% of the cases. In about one-fourth of seronegative cases, antibodies against the MOG protein are present in the serum (MOG-antibody associated disease, MOGAD). This article discusses off-label azathioprine and mycophenolate mofetil in the treatment of NMOSD and reviews the evidence-based clinical aspects of B/plasma cell depletion, antagonization of IL-6 signaling and blocking the complement pathway. The review also summarizes basic aspects of NMOSD pregnancy focusing on treatment, and the different therapeutic approach in MOGAD. In the recent two years, phase 3 clinical trials provided class I evidence for the efficacy and safety of rituximab (anti-CD20), inebilizumab (anti-CD19), tocilizumab (anti-IL6R), satralizumab (anti-IL6R), and eculizumab (anti-C5) in combination with other immunosuppressants or in monotherapy. The treatment approach in MOGAD is complicated by the monophasic course in about half of the cases and by the potential disappearance of MOG antibody. The necessity of maintenance treatment in MOGAD should be decided after tapered oral steroid. Immunosuppression is recommended in NMOSD during pregnancy and lactation, and this should be considered for optimal selection of treatment in fertile female patients. The new monoclonal antibodies broadened treatment options NMOSD, and the treatment strategy of MOGAD has become more straightforward.]
