[How the recognition and treatment of primary aldosteronism could be improved?]

BAJNOK László

[Practically there were no randomized, controlled trials in the area of PA so far, but recently two such ones have appeared. In addition, both are paradigm- forming; yet not built into (yet?) the expert opinions. In the field of primary aldosteronism (PA), there is a sharp contrast between the world’s leading experts in many areas. There is consensus in respect that hypokalaemia, therapy resistance and vascular complications are more common in PA than in primary hypertension. According to prestigious studies, the ratio of surgically correctable cases can be around 5% of hypertension. However, only a tiny fraction of these cases are ever investigated even in the developed countries. Specific treatment might be reached more easily by a multi-speed approach applicable for domestic conditions in which one of the alternatives is the diagnostic process itself. In the latter, following aldosterone criteria are proposed: at screening greater than 15 ng/dl when associated with low renin, in the suppression test, for further testing (adrenal CT) a concentration above 5 ng/dl. This would provide a sufficient balance between sensitivity and specificity. Another solution could be the more widespread use of low dose spironolactone in resistant hypertension.]

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.

CANOMAD syndrome with respiratory failure

SALAMON András, DÉZSI Lívia, RADICS Bence, VARGA Tímea Edina, HORTOBÁGYI Tibor, TÖMÖSVÁRI Adrienn, VÉCSEI László, KLIVÉNYI Péter, RAJDA Cecília

CANOMAD (chronic ataxic neuropathy, ophthalmoplegia, M-protein agglutination, disialosyl antibodies) syndrome is a rare polyneuropathy. IgM paraproteins react with ganglioside-containing disialylated epitopes resulting in dorsal root ganglionopathy and B-lymphocyte infiltration of cranial and peripheral nerves. Clinical features include ataxia, slight muscle weakness, areflexia, sensory- and cranial nerve symptoms. Case studies have reported the efficacy of rituximab and intravenous immunoglobulin (IVIg) treatments. We present the case of a 57-year-old man, who had difficulty walking, with numbness and clumsiness in all limbs. He had areflexia, vibratory sensation loss and ataxia. Laboratory tests showed IgM monoclonal components and disialosyl antibodies in the serum. Nerve conduction studies indicated severe sensorimotor demyelinating polyneuroradiculopathy. Despite IVIg and rituximab treatments, the patient’s disease course gradually worsened and he died of respiratory failure. Neuropathological examination revealed dorsal column- and dorsal root atrophy with mixed mononuclear cell infiltration. This article aims to draw attention to this syndrome, and the use of early potent immunosuppressive treatment to improve patients’ quality of life.

The yield of electroencephalography in syncope

NALBANTOGLU Mecbure, TAN Ozturk Ozlem

Introduction - Syncope is defined as a brief transient loss of consciousness due to cerebral hypoperfusion. Although the diagnosis of syncope is based on a thorough history and examination, electroencaphalography (EEG) is also an important investigational tool in the differential diagnosis in this group of patients. In this study we aimed to identify the diagnostic value of EEG in patients with syncope. Methods - We retrospectively examined EEG recordings of 288 patients with the diagnosis of syncope referred to the Cankiri State Hospital EEG laboratory, from January 2014 to January 2016. The EEG findings were classified into 6 groups as normal, epileptiform discharges (spike and sharp waves), generalized background slowing, focal slowing, hemispherical asymmetries, and low amplitude EEG tracing. The EEGs were separated according to gender and age. Results - Total of 288 patients were included in this study, 148 were females (51.4%) and 140 (48.6%) were males. Among all the EEG reports, 203 (70.5%) were normal, 8 of them (2.8%) showed generalized background slowing and 7 (2.4%) demonstrated focal slow waves. Epileptiform discharges occured among 13 patients (4.5%). Hemispherical asymmetries were detected in 10 patients (3.5%) and low amplitude EEG tracing in 47 patients (16.3%). There was no significant difference between age groups in EEG findings (p=0.3). Also no significant difference was detected in EEG results by gender (p=0.2). Discussion - Although the diagnosis of syncope, epilepsy and non-epileptic seizures is clinical diagnosis, EEG still remains additional method

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]
