[Cough syncope is an infrequently diagnosed form of situational syncope. Most of the reported cases occurs among middle-aged or elderly overweight males, suffering from chronic obstructive lung disease. In our report of four cases we demonstrate the underlying mechanism of cough syncope. Hemodynamic recordings at the time of simulated cough attacks demonstrated the equalisation of the arterial and central venous pressures with consequent cerebral hypoperfusion. The first case illustrates the difficulties of the diagnostic work-up and the confounding effects of the co-existing arrhythmia. The second and fourth cases draw attention to the relationship between cough syncope and accidents. All four patients suffered from chronic obstructive pulmonary disease resulting from heavy smoking which seems to be the most important underlying factor of this syndrome.]

[Localised and generalised osteoporosis in autoimmune polyarthritis]

TÓTH EDIT

[In this article, recent data are summarised on the osteoporosis occurring in autoimmune polyarthritis. Involvement of the bone in patients with autoimmune diseases occurs in two forms: localised (around inflamed joints) and generalised. Paraarticular osteoporosis has been known for a long time but new methods of bone measurements highlight the rate and cause of bone loss. Generalised skeletal changes in rheumatoid arthritis, in systemic lupus erythematosus and juvenile chronic arthritis have been proved by epidemiological studies. At present, there is no evidence supporting generalised bone loss in other chronic inflammatory diseases. Despite the fact that clinically apparent osteoporosis in autoimmune diseases is associated with severe health impairment and reduced survival rates, osteoporosis is still underdiagnosed and prophylactic strategies have yet to be found for this group of patients. These facts indicate calling specialists’ attention to the importance of osteoporosis in inflammatory diseases.]

[A case of restrictive cardiomyopathy due to anthracycline treatment]

HELTAI Krisztina, SZABÓKI Ferenc

[INTRODUCTION - A case of restrictive cardiomyopathy with consecutive arrhythmia is presented which developed 20 years after adriablastin treatment CASE REPORT - A 30 years old women has already been treated for 3 years at an outpatient clinic for paroxysmal supraventricular tachycarcia (PSVT) and shortness of breath. All therapeutic interventions were ineffectual, since the patient refused to take the prescribed medicines because of feeling worse after taking them. This lack of compliance was first explained by vegetative neurosis, but later she was examined with the suspicion of dilatative cardiomyopathy and coronary heart disease. The patient was admitted to the Cardiology Intensive Care Unit with cardiogenic shock which developed after injection of propafenon that had been given due to PSVT. On admission sinus rhythm was seen, but later PSVT and non-sustained VT were recorded. Echocardiography showed diffuse hypokinesis, normal diameter of left ventricle and increased right ventricle pressure. Considering the low EF and the recurring high frequency arrhythmia, amiodarone treatment was introduced successfully. From the medical history of the patient it emerged, that in 1977, she underwent surgery due to neuroblastoma with consecutive combined chemotherapy containing adriablastin. CONCLUSION - It is presumed that the recurring arrhythmia was a consequence of restrictive cardiomyopathy resulting from anthracycline treatment. To prove the diagnosis of restrictive cardiomyopathy echocardiography, Swan-Ganz catheter insertion, coronarography and myocardium biopsy were performed to exclude other possible causes of restrictive cardiomyopathy and to verify the toxic effect of anthracycline.]

[Psychiatric disorders associated with childbearing]

PÁLL Irén

[The aim of this brief literary review was to draw attention to psychiatric disorders accompanying childbearing and to point out their importance. Authors begin with a historical perspective, the definition of concepts and the presentation of epidemiological data. It is followed by the mapping of multiple entwining etiological factors, then focus on the risc factors. Finally the principles are outlined to be followed in screening, prevention and treatment. Although these conditions develop quite frequently and have serious consequences regarding the individual (“unity of mother and child”) as well as the family and the society, their recognition still present difficulties. Following the establishment of the diagnosis, it is also important to start adequate therapy in time. The solution of the future would be to focus on prevention. This would be realized through the teamwork of would-be parents, health care specialists and researchers.]

[Who will remain a member of the Hungarian Chamber of Physicians? - Reflecting on home birth in Hungary]

SZEBIK Imre

[The Hungarian Chamber of Physicians (HCP) has suspended the membership of two physicians since they provided medical care in planned home births. The idea of planned home births is vehemently opposed by the HCP declaring this practice as unprofessional and unethical. There is no scientific evidence from Hungary to justify the opinion of the HCP. Since data from Western European and North American countries suggest that planned home birth may be as safe as hospital birth for certain low risk mothers, an objective scientific research is suggested in Hungary to evaluate the risks of home birth versus hospital birth.]

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

[Diagnosis of epilepsy]

JANSZKY József

[0.5-1% of the population suffers from epilepsy, while another 5% undergoes diagnostic evaluations due to the possibility of epilepsy. In the case of suspected epileptic seizures we face the following questions: Is it an epileptic seizure? The main and most frequent differential- diagnostic problems are the psychogenic non-epileptic seizures ("pseudo-seizures") and the convulsive syncope, which is often caused by heart disorders. Is it epilepsy? After an unprovoked seizure, the information on recurrence risk is an important question. The reoccurrence is more possible if a known etiological factor is present or the EEG shows epileptiform discharges. After an isolated epileptic seizure, the EEG is specific to epilepsy in 30-50% of cases. The EEG should take place within 24 hours postictally. If the EEG shows no epileptiform potentials, a sleep-EEG is required. What is the cause of seizures? Hippocampal sclerosis, benign tumors, and malformations of the cortical development are the most frequent causes of the focal epilepsy. Three potentially life-threatening conditions may cause chronic epilepsy: vascular malformations, tumors, and neuroinfections. The diagnosis in theses cases can usually be achieved by MRI, therefore, MRI is obligatory in all epilepsies starting in adulthood. The presence of epileptogenic lesion has a prognostic significance in treatment. If the MRI shows a circumscribed lesion then the pharmacological treatment will likely to be unsuccessful, while surgery may result in seizure freedom. The new and quantitative MRI techniques, such as volumetry, T2-relaxometry, MR-spectroscopy, and functional MRI play a growing role in the epilepsy diagnosis.]

[Esophageal perforation in pneumectomized patient]

SZÁNTÓ Dezső, SZŰCS Gabriella, DITRÓI Edit

[INTRODUCTION - In 58 per cent of cases the fistulas and perforations are developing in middle third part of the esophagus. CASE REPORT - A 58 year old male patient's left lung was surgically removed due to drug-resistant actinomycosis. The pneumectomy has induced mediastinal dislocation and fibrothorax. Six years later the patient complained of odyno-dysphagia and of swallowing cough. On chest plain film we observed left-sided hydrothorax and barium swallows showed perforation of esophagus at the ipsilateral side. Esophageal adenocarcinoma and exudative pleuritis were confirmed by endoscopy and by histology following thoracocentesis. CONCLUSION - In case of pneumectomized patient with swallowing cough, dysphagy and recently development of pleural fluid collection the diagnosis of esophageal perforation is likely. The pleural pain is usually missing due to postoperative indurative pleurisy.]

[CHRONIC COUGH - THE OTOLARYNGOLOGISTS’ POINT OF VIEW]

GERLINGER Imre

[Chronic cough can have a profound impact on the psychosocial function of patients. Most studies agree that post-nasal drip syndrome (PNDS), asthma, gastro-esophageal reflux disease (GERD), and laryngo-pharyngeal reflux (LPR) are the most common causes of chronic cough in immunocompetent, non-smoking patients who are not taking angiotensin-converting enzyme (ACE) inhibitors and present with a negative chest x-ray. No diagnostic test has yet been found to define those who have PNDS other than the response to a first-generation antihistamine. Examination of the available evidence suggests that the theory of mechanical stimulation of the pharynx by mucus does not explain the occurrence of cough. Inflammatory mediators’ levels in the lower airways are higher in PNDS, cough variant asthma, and GERD, and the theory that an inflammatory process is affecting “one airway” is a plausible one. Nasal disease is more likely to result in cough from the co-existing involvement of the lower airways through a yet undefined pathway. Mediation by eosinophil and mast cells appears to be a likely mechanism. In this paper, the author summarizes all potential pulmonological, otolaryngological and other reasons of chronic cough, suggesting a systematic therapeutic algorithm.]

[CLINICAL ASPECTS OF NOCTURNAL GASTRO-OESOPHAGEAL REFLUX]

DEMETER Pál

[Gastro-oesophageal reflux that occur at night has special clinical features and thus require extra attention. During sleep most anti-reflux mechanisms diminish, which results in prolonged contact between gastric acid and oesophageal mucosa compared to reflux during the day. Nighttime reflux symptoms adversely affect quality of life, vitality, physical and mental health. A further important consequence is the potential exacerbation of respiratory disorders such as asthma and sleep apnea. There is increasing interest in the association between nocturnal reflux and certain extra-oesophageal symptoms, including reflux laryngitis and chronic cough. An increased risk of erosive damage and adenocarcinoma of the oesophagus are also observed among patients who report nocturnal reflux symptoms. The primary goal of treatment is to improve quality of life and reduce the risk of complications by decreasing the time of acid contact with oesophageal mucosa. Nighttime reflux symptoms are much more difficult to control than daytime symptoms. Treatment guidelines generally recommend lifestyle changes as the initial approach in managing nocturnal symptoms, however, this is successful in only a small proportion of patients. Evidence-based reviews and meta-analyses favour the use of proton pump inhibitors in the treatment of gastro-oesophageal reflux disease and reflux-oesophagitis. Proton pump inhibitors are the most efficient acid-suppressing agents and thus diminish the harmful effect of acidic gastric reflux on the oesophageal mucosa. In addition, by decreasing the volume of gastric acid, they reduce the tendency to reflux.]
