[Although Landau-Kleffner syndrome, a childhood-acquired epileptic aphasia, is frequently studied either the underlying pathophisiology or the optimal therapy remained unknown. In our study we aimed to investigate the efficacy of ACTH therapy in Landau-Kleffner syndrome. We have analysed retrospectively the documentation of five children treated by ACTH, who suffered from Landau-Kleffner syndrome. We studied the longitudinal changes of the four most characteristic sympthoms and signs of the syndrome: epileptiform EEG, speech and behaviour disorders, seizures together with the ACTH regimes. Besides, we analysed the relation between the starting date of the therapy and its efficacy. Before giving ACTH, epileptiform EEG and speech disorders were observed in all the five children, seizures in four of them, behaviour disorders in three of them. In two patients the speech disorder had been persisting for years before. Due to the starting ACTH stosstherapy (20 E/day for onetwo weeks) all the four examined signs disappeared or showed quick softening in all the five children in maximum two weeks. We adjusted long-term low dose maintenance therapy to avoid relapses in the long-term follow-up. Epileptiform EEGs have normalised in one case and have decreased in four cases. Speech disorders have disappeared in two and have softened in three children. Behaviour disorders have cured in 3/4 cases, softened in one case. Seizures have disappeared in all cases. One child is totally asymptomatic, four of them lives with softened symptoms. Analysing our data we found that the earlier the therapy starts, the more effective it is. On the basis of our data ACTH is an effective treatment for Landau-Kleffner syndrome. After giving it for only a short period, relapses often occur, to avoid relapses adjustment of long term low dose maintenance therapy is advisable.]

[Pediatric intraventricular tumors]

MARKIA Balázs, GYORSOK Zsuzsanna, KORDÁS Mariann, BOGNÁR László

[Pediatric intraventricular tumors present a well circumscribed group from surgical point of view. These tumors growing in the ventricular system cause hydrocephalus in most of the cases, the presenting symptoms are the signs of raised intracranial pressure. The mass lesion may remain silent for a long period, especially in infancy due to compensatory mechanisms, and the tumor might reach extreme size making the surgery a real challenge. This group has very specific postoperative problems resulting from the disturbance of CSF circulation. In this study we present the retrospective analysis of 55 patient operated for intraventricular tumor in the National Institute of Neurosurgery between 1991 and 2006. Data were analysed regarding histological type, presenting symptoms, type of surgical approach, radicalitiy of the resection and postoperative complications. In addition to our own results brief presentation of the specific histological groups is given based on the available literature.]

[Changes of the immune functions in patients with eating disorders]

PÁLI Anikó Andrea, PÁSZTHY Bea

[Aims - In this study we investigated whether calorie restriction or redundant food intake influences the function of regulatory T cells (Tregs), and their main regulators (dendritic cells and macrophages), or the targets of Tregs, CD4+ lymphocytes. Patients and methods - We investigated 11 white adolescents (10 girls and 1 boy) with anorexia nervosa, 12 obes adolescents and 10 healthy controlls. With flow cytometry we determined the prevalence of Tregs, myeloid and plasmacytoid dendritic cells. We applied intracellular staining to investigate TNF-alpha and IL-12 production of macrophages, moreover IL-2, IL-4, and IFN-gamma production of CD4+ cells. We also determined calcium flux kinetics upon activation in CD4+ cells. Results - We did not find any difference between obese, anorectic and control individuals in the prevalence of Tregs, dendritic cells, TNF-alpha and IL-12 positive macrophages, IL-4 and IFN-gamma positive CD4+ lymphocytes. We found that the prevalence of IL-2 positive lymphocytes after activation was lower in anorectic than in control subjects [median (range): 11.50 (7.60-15.30) vs. 13.50 (12.00-22.00), p=0.023], and in obese patients, too [12.50 (8.50-15.50) vs. 13.50 (12.00-22.00), p=0.028]. IFN-gamma/IL-4 ratio in CD4+ cells was higher in obese patients compared with control (p=0.046). The calcium flux characteristics of lymphocytes upon activation differed markedly in anorectic and healthy subjects as maximal calcium levels developed later in anorectic patients [86 (45- 232) vs. 215 (59-235) second, p<0.05]. We also tested the association between lymphocyte activation parameters and patients' clinical status, but did not find any association between the variables. Discussion - Our results suggest that the antigen presenting cell - regulatory T cell - CD4+ lymphocyte axis might be affected by calorie and nutritional disturbances, further studies are needed to elucidate the underlying processes.]

[Pneumococcal meningitis in children - 9 1/2-year-experience at Szent László hospital, Budapest, Hungary ]

IVÁDY Balázs, LIPTAI Zoltán, ÚJHELYI Enikő, BALÁZS György

[Background and objective - No recent publications are available about pneumococcal meningitis in Hungarian children. The aim of this study was to collect data of epidemiological, clinical and prognostic features of pneumococcal meningitis in children treated at Szent László Hospital, Budapest, Hungary. Methods - We conducted a retrospective review of medical charts and follow-up records of patients aged 1 to 18 years admitted to our Pediatric and Pediatric Intensive Care Units due to pneumococcal meningitis between 1st Jan 1998 and 30th Jun 2007. Results - 31 children with 34 cases of pneumococcal meningitis were admitted to our hospital in the study period. Two children developed recurrent illness. The mean age was 6 years, 26% were under 1 year of age. The mean duration of hospital stay was 21 days, 97% required intensive care. Frequent clinical symptoms were fever (100%), nuchal rigidity and vomiting (78%), altered mental status (71%), Kernig's and Brudzinski's signs (58%) and seizures (41%). Otitis media, sinusitis, mastoiditis were present in 44%, 58%, 41%, respectively. Subdural effusion, parenchymal cerebral lesion and sinus thrombosis were documented in 5, 3 and 2 cases, respectively. One third of the patients recieved ceftriaxon, two thirds were administered ceftriaxon and vancomycin. Adjunctive therapy with dexamethason was given to 91% of the children. 70% of patients required mechanical ventillation. 9 patients (25%) required endoscopic sinus surgery. In 13 cases (38%) mastoidectomy, in 5 children (15%) neurosurgery was performed. The case fatality rate was 23.5%. 8 (23.5%) patients had mild or moderate, 1 child (3%) developed severe neurological sequelae. Conclusion - Pneumococcal meningitis in children remains a source of substantial morbidity and mortality in childhood. The long hospital stay, the frequent need for intensive care and severe neurologic sequelae emphasize the importance of early diagnosis, early treatment and prevention with pneumococcal conjugate vaccines.]

[Devastating epileptic encephalopathypseudoencephalitis: the new type of catastrophe epilepsy in our department]

NEUWIRTH Magdolna, PARAICZ Éva, LIPTAI Zoltán

[Purpose - Analysis of history of our five patients with intractable epilepsy whose illnes have begun with prolonged status epilepticus (SE) and high-grad fever of unknow cause. Methods - Retrospective study analysis of selected five intractable epileptic patients at a median age of 11.5 (8-14) years. Results - All children had normal development before epilepsy begun. Intractable SE lasted 3-10 (median seven) days by four patients and three months by one patient. The cause of illness was unknow at the beginning and the MRI were normal. Intractable epilepsy followed the SE in all cases without any latent period. Follow-up of the children was 3-15 (median 9.5) years. The seizures came continually with few-day-long breaks, antiepileptic drugs were ineffective. Semiology of seizures, EEG, and functional imaging examinations (PET, SPECT) referred to temporal and frontal lobe damages. Later on, the MR images showed hippocampal sclerosis in one patient and mild generalized brain atrophy in the others. During the years, cognitive deterioration and behavioral problems have been realized. The most severe patient developed tetraparesis, fell in vigil coma and died after five years. Conclusions - The symptoms of our patients fulfilled the criteria of devastating epileptic encephalopathy in schoolaged children.]

[How do temporal lobe seizures changeby age?]

FOGARASI András

[Seizure semiology describes different - motor, sensory, autonomic, etc. - aspects of epileptic seizures. Several semiological studies showed already that different epilepsies - especially temporal lobe epilepsy - contain age-dependent features. In our researches, we tried to assess these subjective aspects with as objective methods as possible. We gave a comprehensive (preictal, ictal, and postictal) description of seizure semiology in patients fulfilling the gold standard criteria of semiological studies: being seizure free after temporal lobe resections. Our studies based on a large population, assess epileptic features at different levels of brain maturation. They help to understand why certain semiological axes show special characteristics at different ages. In this review, I summarize the most important results of our seizure semiology studies in temporal lobe epilepsy.]

[The history of diuretic treatment in Hungary. Part I. Imre Fodor]

RADÓ János

[The diuretic effect of mercurial compounds was discovered in 1920. However, the term of “mercurial diuresis” was created 36 years earlier by Ernő Jendrassik. Imre Fodor published his experiences with the mercurial diuretic, which has been cited by several authors worldwide. The Hungarian pharmaceutical industry also took its part from the production of the mercurial diuretic with Novurit that proved to be an excellent and worldwide well known preparation in the next 40 years. Even Imre Fodor required the repeated administration of mercurial diuresis because of his severe cardiac oedema in the last period of his life. When the drug became ineffective, i.e. developed refractory oedema, he made a “self-experiment” with the administration of ACTH to restore the sensitiveness to the mercurial diuretic on the basis of most recent American literature at that time. His experience has been published by his colleagues just before his death. Imre Fodor was an eminent clinician, a school creating internist who entered his name into the science dealing with the use of diuretics.]

ALTAY Servet, GÜRDOGAN Muhammet, KAYA Caglar, KARDAS Fatih, ZEYBEY Utku, CAKIR Burcu, EBIK Mustafa, DEMIR Melik

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

A rare entity of acquired idiopathic generalised anhidrosis which has been successfully treated with pulse steroid therapy: Does the histopathology predict the treatment response?

ÖKTEM Özdemir Ece, ÇANKAYA Şeyda, UYKUR Burak Abdullah, ERDEN Simsek Nazan, YULUG Burak

Acquired idiopathic generalised anhidrosis is an uncommon sweating disorder characterized by loss of sweating in the absence of any neurologic, metabolic or sweat gland abnormalities. Although some possible immunological and structural mechanisms have been proposed for this rare entity, the definitive pathophysiology is still un­clear. Despite some successfully treated cases with systemic corticosteroid application, the dose and route of steroid application are controversial. Here, we present a 41-year-old man with lack of genera­lised sweating who has been successfully treated with high dose pulse intravenous prednisolone. We have discussed his clinical and histopathological findings as well as the treatment options in view of the current literature.

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm

BÉRES-MOLNÁR Anna Katalin, FOLYOVICH András, SZLOBODA Péter, SZENDREY-KISS Zsolt, BERECZKI Dániel, BAKOS Mária, VÁRALLYAY György, SZABÓ Huba, NYÁRI István

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.
