Lege Artis Medicinae - 1993;3(09)

[Circulatory failure worsened to the point of discontinuation in 23 patients in the diuretic + ACE inhibitor + placebo only group, compared to only four patients in the digoxin group (p<0.001). The relative odds of worsening circulatory failure with placebo compared with digoxin was 5.9. All measured parameters of functional capacity (maximal exercise capacity, submaximal exercise capacity, NYHA grade) worsened with digoxin withdrawal. Similarly, quality of life (p=0.04), ejection fraction (p=0.001), heart rate (p<0.001) and body weight (p<0.001) decreased with digoxin instead of placebo.]

[What to expect of PTCA today?]

MAJOR László, MOLNÁR Ferenc, BERENTEY Ernő, KÉKES Ede

[This article is a review of the changing indications for percutaneous coronary angioplasty during the last decade. The role of revascularisation and especially of PTCA in the treatment of coronary heart disease is explained. Coronarography is the most important morphol gic diagnostic tool for coronary artery disease. The importance of the topic of this article is enhanced by the position of Hungary at the top of morbidity and mortality statistics, and by the infrequency of revascularisation procedures, especially PTCA. PTCA proved to be a real alternative to a surgical procedure in about half of the patients indicated for revascularisation. PTCA is less invasive, requires less time for recovery and is less expensive compared to bypass surgery. This article should draw attention of the family practitioner to the importance of this method. ]

[Myocardial contrast echocardiography]

TEMESVÁRI András, LENGYEL Mária, PAOLO Voci

[Symptoms of ischemic heart disease will occur when myocardial perfusion diminishes below a critical level. Coronarography will disclose the anatomic stenoses, but there is no direct correlation between the grade of stenosis and the change of myocardial perfusion. Myocardial contrast echocardiography is a new technique to analyze the myocardial perfusion. The contrast agent contains micro bubbles which have nearly the same dimensions as red blood cells. The microbubbles increase the „whiteness" of the perfused myocardium during the echocardiographic examinations. The change in „whiteness" of the myocardium correlates with myocardial perfusion. Intracoronary injections delineate the perfusion area of the coronary artery, and Thus the coronary flow reserve and the collateral flow area can be measured. The cardioplegia fluid distribution and the graft perfusion area are examined intraoperatively. Bedside myocardial perfusion studies will be possible through the transpulmonary passage of intravenously injected contrast agents. Myocardial contrast echocardiography can be applied both in the diagnosis and treatment of ischemic heart disease.]

[Investigation of uterine circulation by transvaginal color doppler in early pregnancy]

SZABÓ István, CSABAY László, NÉMET János, PAPP Zoltán

[The circulatory changes and the characteristics of blood flow in certain uterine vessels can be detected by transvaginal color Doppler in early pregnancy. The uterine circulation of 53 patients with normal intrauterine pregnancies at 4–14 weeks of gestation and 104 non pregnant patients were investigated. The main uterine artery, arcuated and spiral arteries were demonstrated by color Doppler in all patients in early pregnancy and characteristic flow velocity waveforms were obtained in 94% of the cases. The impedance to flow in the main uterine artery was significantly lower and the mean velocity was significantly higher in early pregnancy than in non pregnant patients. The indices of impedance to flow decreased with gestation in the uterine branches and there was a progressive fall in these indices from the uterine artery to the spiral arteries. Mean blood velocity in the uterine artery increased with gestation. The hemodynamical changes which are proportional to gestation age give an indirect evidence of the adequate maternal blood supply for the growing embryo.]

[Health insurance chances]

FRENKL Róbert

[Every Hungarian citizen has the right to the highest quality of health care free of charge.This was the basic tenet of the socialist health care system, which, with its hypocrisy and lies, made all reform efforts hopeless from the start. Worse still, for successive generations of doctors, unreality became the defining feature, and the only protection against its demoralising effects was the closeness of a few worthy individuals, their professionalism and human decency. ]

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.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[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.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.

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.
