[A CASE OF MISIDENTIFIED SYNCHRONOUS COLON CANCER]

CSERNI Gábor, BORI Rita, OLÁH Csaba, HAUSINGER Péter, TUSA Magdolna, MARKÓ László, SVÉBIS Mihály

[INTRODUCTION - Synchronous colorectal cancers are not uncommon, therefore, total colonoscopy is indicated even in cases of distally located large bowel carcinomas. CASE REPORT - An 84-year-old man had emergency surgery because of bowel obstruction and a node-negative carcinoma of the sigmoid colon was removed according to Hartmann. Before the reconstruction of bowel continuity, colonoscopy revealed a relatively small polypoid tumour in the right colon, unsuitable for colonoscopic polypectomy. Two localization clips were then inserted at the site of the endoscopic biopsy that later resulted in the diagnosis of adenocarcinoma. At the time of the reconstruction surgery, an appendectomy was also performed and, though the clips were not found, the polypoid tumour was removed through appendectomic orifice. The polyp thus removed, however, proved to be an adenoma. A repeated colonoscopy and biopsy confirmed both the localization clips and the malignant nature of the remaining right-sided lesion, which was finally removed with right hemicolectomy. CONCLUSION - Anatomic localization of rightsided colon cancers by colonoscopy is often imprecise. The correct identification of a malignant tumour may be compromised by a nearby benign lesion. If a lesion was labelled by some means, the localization sign should be identified both intraoperatively and during the gross pathologic work-up, asking for external help (e.g., radiology in case of a metal clip) if necessary.]

[MYELODYSPLASTIC SYNDROMES - NEW THERAPEUTIC OPTIONS]

GADÓ Klára

[Myelodysplastic syndrome is a heterogeneous group of acquired clonal disorders of the haematopoietic stem cell characterized by ineffective haematopoiesis, peripheral cytopenia, and a high risk of progression to acute leukaemia. It is a common malignant disease with an increased incidence in the elderly population. Classification is based on a 1999 WHO recommendation, in which morphological features as well as clinical and cytogenetic characteristics are taken into account. Combined with the International Prognostic Scoring System (1997), it is suitable to predict prognosis and response to therapy. Clinical features include symptoms caused by anaemia, infections, and bleeding. Diagnosis is based on peripheral cytopenia and dysplastic morphology, as well as normal or increased cellularity in the bone marrow, with more than 10% of dysplastic cells. The verification of cytogenetic abnormalities is important both for confirming the diagnosis and predicting the prognosis. When designing the treatment strategy, it is essential to take the risk of leukaemia into account. On the other hand, the general state of the patient and the presence of accompanying diseases should also be considered. The goal of the treatment is to increase cell count and to decrease transfusion requirement, eventually to improve quality of life. Supportive therapy is an essential part of the management. In addition, growth factors, immunosuppressive and immunomodulatory agents, low-dose chemotherapy may be applied. Today, cure can only be achieved by allogenic stem cell transplantation. Recent findings in the epigenetic intracellular regulation allowed the definition of new therapeutic targets to develop drugs such as inhibitors of DNA methyltransferase and histone deacetylase.]

[THE ROLE AND METHODS OF IMPROVING INSULIN SENSITIVITY AND BETA-CELL FUNCTION IN TYPE 2 DIABETES]

GYIMESI András, TÁRNOK Enikő, TAYBANI Zoltán

[Increased knowledge on the pathogenesis of type 2 diabetes has considerably transformed the principles and practice of treatment. Insulin resistance and beta-cell dysfunction, the two main components of the pathogenesis both play a role in the conversion of normal glucose metabolism, through impaired glucose tolerance, into type 2 diabetes. Decreased insulin sensitivity, with or without beta-cell dysfunction, is present in the vast majority cases, therefore, its treatment is essential. Physical activity is known to improve insulin sensitivity. The primary action of the recommended first-line pharmacological agent metformin is the inhibition of hepatic glucose production but it also moderately stimulates muscle glucose uptake. Glitazones are insulin sensitizers that increase glucose uptake in muscle and adipose tissue and moderately decrease hepatic glucose production. Some evidence suggests that α-glucosidase inhibitors and also certain insulin secretagogues can improve the effect of insulin. Early detection of the pathologic state and an efficient treatment to improve both insulin sensitivity and beta-cell function are essential in order to slow the progression and prevent the development of complications in type 2 diabetes.]

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.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

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.
