[The role of transesophageal echocardiography in the investigation of stroke]


DECEMBER 28, 1994

Lege Artis Medicinae - 1994;4(12)

[Ischaemic infarction accounts for 85% of stroke aetiology (1). Approximately 60-70% of these are of cerebrovascular, i.e. carotid arteriosclerosis, origin (2). The proportion of cardiogenic embolism was previously estimated at 15% (1), but autopsy data suggest that embolism is the cause of half of fatal strokes (3). There are two reasons for this large discrepancy: 1) the intracardiac source is difficult to identify in vivo; 2) cardiogenic embolism has a more severe outcome than stroke of other origin. Probably both are true, but there is no doubt that before the introduction of transesophageal echocardiography (TE), the detection of intracardiac sources was rare and uncertain.]

[The first 15 years of the AIDS epidemic ]


[AIDS represents the most exciting infectious disease of the last 15 years. In addition to the fact that there are more than 4 million estimated AIDS patients and more than 16 million estimated HIV-infected individuals this can be explained by the peculiar features of the disease, including limited routes of infection, long latency period, a quasi 100% lethality, diversity of the clinical picture, difficulties in therapy and vaccination, the theoretically 100% possibility of prevention and the serious social problems associated with AIDS. After giving a short review of the development of our knowledge about AIDS, the author to explains the special features of AIDS mentioned above on the basis of the structure, regulation and replication cycle of the virus. The primary conclusion is that education and prevention should be stressed in the battle against AIDS.]

[A multicentre, randomised, crossover, double-necked trial of contamination of conventional and bow-tie dressings in routine obstetric and gynaecological practice]

MARINKO M Biljan, CHARLES A Hart, DEBORAH Sunderland, PAUL R Manasse, CHARLES R Kingsland

[In the 19th century, the usual dress of doctors was a small bow tie tied in a flat knot "once round" in addition to a stiff standing collar (1). As fashions have changed, the wearing of bow ties has become less common and is now worn almost exclusively by a small minority of obstetricians, who often claim that they are more hygienic than the traditional tie in the delivery room, which is contaminated with blood and amniotic fluid. There is currently no evidence for this. We therefore examined the contamination of traditional and bow ties worn by obstetricians during a typical working week. ]

[Clinical and laboratory parameters in ulcerative colitis]

NAGY Ferenc, PAPÓS Miklós, CSERNAY László

[The clinical and laboratory parameters which correlate with the intensity of the inflammatory process in ulcerative colitis patients were analyzed in this study. The severity of the inflammatory process was assessed with leukocytescinti graphy by colorectal segments using a scoring method in 36 patients (group A). The sum of the segmental scores were considered to represent the intensity of the inflammatory process and were compared with clinical and laboratory parameters. From among the 36 patients, acute ulcerative colitis was established with biopsy in 30 cases. Two toxic patients were not tested and four patients had inactive disease. In 20 (16 acute, 4 inactive) of 36 patients, the intensity of the inflammatory process was assessed by segments with score values of biopsy samples and leukocyte scintigraphy (group B). The sum of the score values was used to determine the correlation of the two methods. The intensity of the inflammatory process assessed by scintigraphy showed a good correlation (r = 0.6564, p = 0.0016) with histological findings (group B), as well as with the ESR (r = 0.6398), serum fibrinogen (r = 0.5424), alfa2 globulin level (r = 0.4721), number of bloody stools (r = 0.4605), and the thrombocyte count (r = 0,4594) in group A. Five clinical and laboratory parameters proved to be suitable to assess the actual severity of the inflammatory process in ulcerative colitis. The values of the parameters may help to choose the right examination in new cases and to evaluate the efficacy of the therapy. ]

[Prenatal diagnosis of endocardial fibroelastosis]

KÁDÁR Krisztina, KIRÁLY László

[The authors report two cases of prenatally diagnosed endocardial fibroelastosis with echocardiography for the first time in Hungary. This disease is rare and usually fatal. Diagnoses were confirmed by autopsy and in one case by postnatal echocardiography as well. Principles for the diagnosis of endocardial fibroelastosis are discussed. Echocardiography makes possible the prenatal diagnosis of endocardial fibroelastosis and is recommended from the 18th week of pregnancy in high risk individuals.]

[Is pay for performance a viable option in the health sector?]


[After reviewing our department's employment statistics a few weeks ago, I was not surprised to see that we have performed almost twice as many radiology examinations in the past year as the Royal College of Radiologists' recommended number of examinations. Since 1990, the number of outpatient examinations in our department has increased by 48%, the number of inpatient examinations by 13% and the number of accident and emergency examinations by 6%. Most other specialists could report similar figures.]

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.

[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. 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. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]

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


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 connection between the socioeconomic status and stroke in Budapest]


[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[The Comprehensive Aphasia Test in Hungarian]


[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. ]
