[Ultrasonic signs of suspected fetal chromosomal aberration]

ÁDÁM Zsolt, NÉMET János, SZABÓ István, CSABAY László, TÓTH-PÁL Ernő, HAJDÚ Júlia

[The authors summarize the relevant ultrasonic findings in case of suspected fetal chromosomal aberration. Some of these signs are detectable during routine ultrasonic screening examinations. In high-risk cases, prenatal chromosomal analysis is recommended. The following ultrasonic findings indicate a situation of high risk: disturbances of the lymphatic and amniotic fluids (e.g. hydrops, hygroma colli, polyhydramnios, nuchal edema), certain skull and brain alternations, abnormalities of the thorax and abdomen, and „minor” findings such as a single umbilical artery, choroid plexus cyst, pyelectasy, or changes in the size or shape of the long tubular bones, if these signs are accompanied by other anomalies or growth retardation.]

[Advantages and limits of the open tube and flexible esophagoscopes]

TÓTA Julianna, IRÁS Béla

[The two types of endoscopes presently available for examination and treatment of the esophagus are the traditional open tube esophagoscope and the flexible endoscope. Despite the many advantages offered by the flexible endoscope, its limitations should not be forgotten. The open tube esophagoscope should not be thought of as out-of-date, since its new variations have important therapeutic applications. The authors examine the advantages and disadvantages of the two types of esophagoscopes as discussed in the literature. ]

[An update on obstructive sleep apnea]

METES Ágnes, HIRSCHBERG Andor

[Obstructive sleep apnea, which occurs in approximately 2% of the adult population, is the more common of the two major forms of sleep apnea. The conse quences and dangers of excessive daytime sleepiness are emphasized along with the other well-known characteristics of sleep apnea syndrome. Both the decreased upper airway muscle tone during sleep and the negative pressure due to breathing through the obstructed airways may cause upper air ways to collapse. The history has a very important role in the clinical assessment, while the role of the physical examination is limited. An exact and reliable diagnosis may be arrived at through laboratory evaluation, e. g. polysomnography (PSG), Multiple Sleep Latency Test (MSLT), or radiologic examinations. Among conservative treatments, reduction of the body weight is usually effective in mild to moderate cases. In severe apneas, nasal continuous positive airway pressure (nCPAP) is the current treatment of choice. The efficacy of surgical intervention is still controversial. According to most authors, uvulopalatopharyngoplasty (UPPP) has a 50% success rate. Most recently good results have been obtained with maxillo-facial surgery in a variety of selected patients. ]

[The role of echocardiography in the management of ventricular free wall rupture ]

PÁL Mátyás, LENGYEL Mária

[Our goal was to evaluate which diagnostic and therapeutic approaches could provide a better chance of survival. Between January 1, 1987, and December 7, 1992, 772 patients with acute myocardial infarction were treated in the Hungarian Institute of Cardiology. Cardiac rupture was investigated by the retrospective analysis of clinical data, electrome chanical dissociation, echocardiographic signs and autopsy findings. Ventricular free wall rupture was found in 28 cases. The diagnosis was confirmed by autopsy in 23, by intraoperative findings in 4 cases, and by echocardiography and pericardiocentesis in 1 case. Pericardial effusion was detected in 12 of 14 cases undergoing emergency echocardiography. Seven of these had pericardiocentesis and 2 patients underwent surgical pericardial fenestration. Following this 4 patients were referred to surgery. All 4 patients died: 2 during and 2 shortly after operation. The bleeding stopped in 1 case, after pericardiocen tesis and continous drainage and during the 12 month follow-up the patient is alive and well. In acute myocardial infarction, electromechanical dissociation or signs of tamponade are indications for emergency echocardiography, and if pericardial effusion can be visualized, pericardiocentesis should be performed. This can lead to a temporary haemodynamic improvement, providing sufficient time for emergency surgery.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study

NALBANTOGLU Mecbure, AKALIN Ali Mehmet, GUNDUZ Aysegul, KIZILTAN Meral

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[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.]
