[A simple photocopy technique for histological slide preparations of surgically removed specimens is described. Standard office copy machines may be used for this method which is faster than traditional photography and cheaper than polaroid technique. Significant information is quickly provided by the copies for both the physician and the pathologist, including location and extent of the lesion, the state of its neighbouring structures and the resection margins. Retrospective identification of the tissue sections chosen for histological investigation is also facilitated. Despite some technical limitations, this copy technique may effectively support the diagnostic work of the surgical pathologist.]

[Ultrasonic signs of suspected fetal chromosomal aberration]

ÁDÁM Zsolt, NÉMET János, SZABÓ István, CSABAY László, TÓTH-PÁL Ernő, HAJDÚ Júlia

[The authors summarize the relevant ultrasonic findings in case of suspected fetal chromosomal aberration. Some of these signs are detectable during routine ultrasonic screening examinations. In high-risk cases, prenatal chromosomal analysis is recommended. The following ultrasonic findings indicate a situation of high risk: disturbances of the lymphatic and amniotic fluids (e.g. hydrops, hygroma colli, polyhydramnios, nuchal edema), certain skull and brain alternations, abnormalities of the thorax and abdomen, and „minor” findings such as a single umbilical artery, choroid plexus cyst, pyelectasy, or changes in the size or shape of the long tubular bones, if these signs are accompanied by other anomalies or growth retardation.]

[Advantages and limits of the open tube and flexible esophagoscopes]

TÓTA Julianna, IRÁS Béla

[The two types of endoscopes presently available for examination and treatment of the esophagus are the traditional open tube esophagoscope and the flexible endoscope. Despite the many advantages offered by the flexible endoscope, its limitations should not be forgotten. The open tube esophagoscope should not be thought of as out-of-date, since its new variations have important therapeutic applications. The authors examine the advantages and disadvantages of the two types of esophagoscopes as discussed in the literature. ]

[An update on obstructive sleep apnea]

METES Ágnes, HIRSCHBERG Andor

[Obstructive sleep apnea, which occurs in approximately 2% of the adult population, is the more common of the two major forms of sleep apnea. The conse quences and dangers of excessive daytime sleepiness are emphasized along with the other well-known characteristics of sleep apnea syndrome. Both the decreased upper airway muscle tone during sleep and the negative pressure due to breathing through the obstructed airways may cause upper air ways to collapse. The history has a very important role in the clinical assessment, while the role of the physical examination is limited. An exact and reliable diagnosis may be arrived at through laboratory evaluation, e. g. polysomnography (PSG), Multiple Sleep Latency Test (MSLT), or radiologic examinations. Among conservative treatments, reduction of the body weight is usually effective in mild to moderate cases. In severe apneas, nasal continuous positive airway pressure (nCPAP) is the current treatment of choice. The efficacy of surgical intervention is still controversial. According to most authors, uvulopalatopharyngoplasty (UPPP) has a 50% success rate. Most recently good results have been obtained with maxillo-facial surgery in a variety of selected patients. ]

[The role of echocardiography in the management of ventricular free wall rupture ]

PÁL Mátyás, LENGYEL Mária

[Our goal was to evaluate which diagnostic and therapeutic approaches could provide a better chance of survival. Between January 1, 1987, and December 7, 1992, 772 patients with acute myocardial infarction were treated in the Hungarian Institute of Cardiology. Cardiac rupture was investigated by the retrospective analysis of clinical data, electrome chanical dissociation, echocardiographic signs and autopsy findings. Ventricular free wall rupture was found in 28 cases. The diagnosis was confirmed by autopsy in 23, by intraoperative findings in 4 cases, and by echocardiography and pericardiocentesis in 1 case. Pericardial effusion was detected in 12 of 14 cases undergoing emergency echocardiography. Seven of these had pericardiocentesis and 2 patients underwent surgical pericardial fenestration. Following this 4 patients were referred to surgery. All 4 patients died: 2 during and 2 shortly after operation. The bleeding stopped in 1 case, after pericardiocen tesis and continous drainage and during the 12 month follow-up the patient is alive and well. In acute myocardial infarction, electromechanical dissociation or signs of tamponade are indications for emergency echocardiography, and if pericardial effusion can be visualized, pericardiocentesis should be performed. This can lead to a temporary haemodynamic improvement, providing sufficient time for emergency surgery.]

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.

Capability of stroke scales to detect large vessel occlusion in acute ischemic stroke – a pilot study

TÁRKÁNYI Gábor, KARÁDI Nozomi Zsófia, CSÉCSEI Péter, BOSNYÁK Edit, FEHÉR Gergely, MOLNÁR Tihamér, SZAPÁRY László

Rapid changes of stroke management in recent years facilitate the need for accurate and easy-to-use screening methods for early detection of large vessel occlusion (LVO) in acute ischemic stroke (AIS). Our aim was to evaluate the ability of various stroke scales to discriminate an LVO in AIS. We have performed a cross-sectional, observational study based on a registry of consecutive patients with first ever AIS admitted up to 4.5 hours after symptom onset to a comprehensive stroke centre. The diagnostic capability of 14 stroke scales were investigated using receiver operating characteristic (ROC) analysis. Area under the curve (AUC) values of NIHSS, modified NIHSS, shortened NIHSS-EMS, sNIHSS-8, sNIHSS-5 and Rapid Arterial Occlusion Evaluation (RACE) scales were among the highest (>0.800 respectively). A total of 6 scales had cut-off values providing at least 80% specificity and 50% sensitivity, and 5 scales had cut-off values with at least 70% specificity and 75% sensitivity. Certain stroke scales may be suitable for discriminating an LVO in AIS. The NIHSS and modified NIHSS are primarily suitable for use in hospital settings. However, sNIHSS-EMS, sNIHSS-8, sNIHSS-5, RACE and 3-Item Stroke Scale (3I-SS) are easier to perform and interpret, hence their use may be more advantageous in the prehospital setting. Prospective (prehospital) validation of these scales could be the scope of future studies.

[Effective therapy in highly active pediatric multiple sclerosis ]

MERÔ Gabriella, MÓSER Judit, LIPTAI Zoltán, DIÓSZEGHY Péter, BESSENYEI Mónika, CSÉPÁNY Tünde

[Multiple sclerosis (MS) is typically a disease of young adults. Childhood MS can be defined in patients under 18 years of age, although some authors set the limit un­der the age of 16 formerly known as “early-onset multiple sclerosis” or “juvenile multiple sclerosis”, seen in 3-5% of all MS patients. Nowadays, owing to ever-evolving, better diagnostic tools and well-traced, strictly defined diagnostic criteria, childhood MS is showing an increasing incidence worldwide (0.05-2.85/100 000). MS is characterized by recurrent episodes of the central nervous system with demyelination separated in space and time. In childhood almost exclusively the relapsing-remitting (RR) type of MS occurs. Based on experience in adults, the goal in the pediatric population is also the early diagnosis, to initiate adequate DMT as soon as possible and to achieve symptom relief and good quality of life. Based on efficacy and safety studies in the adult population, inter­feron β-1a and glatiramer acetate were first approved by the FDA and EMA for the treatment of childhood MS also. The increased relapse rate and rapid progression of childhood MS and unfavorable therapeutic response to nearly 45% of the first DMT necessitated the testing of more effective and second-line drugs in the population under 18 years of age (PARADIGMS, CONNECT). Although natalizumab was reported to be effective and well-tolerated in highly active RRMS in childhood, evidence based studies were not yet available when our patients’ treatment started. In this article, we report on the successful treatment of three active RRMS patients with individually authorized off-label use of natalizumab.]

[A case of destructive cervical spondylarthropathy related to chronic dialysis]

BERTA Balázs, KOMÁROMY Hedvig, SCHWARCZ Attila, KAJTÁR Béla, BÜKI András, KUNCZ Ádám

[A case of a 61-year-old male patient suffered chronic renal failure and dialysed for 23 years with destructive cervical spondylarthropathy is presented. The patient presented with sudden onset of cervical pain radiating into his shoulders without neurological deficits. CT and MRI of the cervical and thoracic spine revealed severe destructive changes and compressive fractures of C6 and C7 vertebrae which caused the narrowing of the nerve root canals at these levels. A 360-degree fixation was performed to treat the unstable fracture and the patient’s pain (C6 and C7 corpectomy, autolog bone graft replacement of the two vertebral bodies, anterior plate fixation and posterior instrumentation with screws and rods). Postoperatively the patient had no significant pain, no neurological deficit and he was able to manage independent life himself. During the immediate follow-up CT of the neck showed the satisfactory position of the bone graft and the metal implantations. The 6 months follow-up CT revealed the anterior migration of the two screws from the Th1 vertebral body and 2 mm ventral elevation of the caudal end of the plate from the anterior surface of the Th1 vertebral body. The 1-year follow-up could not be performed because the patient died due to cardio-pulmonary insufficiency. This is the second Hungarian report of a chronic dialysis related severe spondylarthropathy which may cause pathologic fractures of the vertebral bodies. The typical radiological and histological findings are discussed. This disease affect patients’ quality of life and the conservative treatment alone seems to be ineffective in most cases. Based on the literature and personal experiences, the authors suggest 360-degree fixation of the spine to provide sufficient stability for the vertebrae of ”bad bone quality”, and early mobilisation of the patient can be achieved.]
