[On pulmonary tuberculosis]

SCHWEIGER Ottó

[The author evaluates the epidemiological conditions of pulmonary tuberculosis in Hungary. The number of new cases decreases year after year. Being the disease infectious afterall, efforts must be continued against it adapted to the new epidemiological situation. This requires the collaboration of all the medical network systems as the pulmonological one is inefficient itself. Though the disease is rare, it cannot be forgotten and in certain cases tuberculosis must be borne in mind as well.]

[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.]

[The importance of tuberculosis in childhood]

ANDRÁSOFSZKY Barna

[Nowadays tuberculosis has already become a rare disease in childhood in Hungary but the danger of the infection is still present for the several thousand (over 3500) disease manifestations among adults. The main task of the pediatricians is prevention, however the disease should be borne in mind in case of unelucidated chronic cases. In suspicion of meningitis basilaris it is necessary to start the treatment at once. Until now the maintanence of the BCG vaccination by age groups (new-born, 11 and 18 years) was justified, but it needs further restriction due to the advance in epidemic situation.]

[Some problems and characteristics of pulmonary mycobacteriosis in hungary]

KOZMA Dezső, VINCZE Egon, DÁVID Sándor, KISHINDI Katalin, ALEXY György

[360 cases of pulmonary mycobacteriosis caused by atypical mycobacteria were observed between 1980 and 1989. M. xenopi proved to be the most frequent pathogen (in 67% of the cases) followed by M. kansasii and M. avium intracellulare. The disease was common in urban-industrial areas. The yearly incidence of disease has not been increased during the observed period. 86% of patients were male with the mean age of 55 years. Underlying diseases such as pulmonary tuberculosis and chronic obstructive lung disease were found frequently. The symptoms of the disease were uncharacteristic. Thin-wall cavities with the lack of an infiltrate appeared in 24% of the patients. Malignancy and pulmonary aspergillosis were the two more frequent concomitant diseases. The occurence of lung cancer and also other organ cancers were significant higher among these patients than in the normal population between 40–69 years of age. Findings of histopathology were indistinguishable from tuberculosis among M. kansasii cases. A relative lack of caseousiting necrosis, forced fibrosis, foreign body reaction and abortive granuloma formation appeared among M. xenopi and M. avium-intracellulare cases. ]

[An update on BCG vaccination]

NYERGES Gáborné, DRINÓCZY Mária

[Tuberculosis is still a serious and wide-spread disease affecting mainly people living under poor hygienic conditions. Double infections with HIV + M. tuberculosis, however, may worsen the epidemiological situation both in developing and highly developed countries. Since its introduction, BCG vaccine has undergone several changes regarding the production strain and other characteristics. Though, the effectivity of BCG vaccination has been often questioned, it is indisputable that the vaccine protects young children against the disease. In Hungary, lyophilised „Paris" BCG strain has been safely and successfully used for vaccinating new-borns and revaccinating children for 30 years. The tbc incidence of the population under 14 years of age has been very low. Due to the relatively high tbc incidence among adults and the unfavourable tendency in the epidemiology of tbc in the world, however, no changes in the present BCG vaccination schedule are advisable. Moreover revaccination regardless to the tuberculin status should be considered. ]

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.

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.
