[NONINVASIVE MECHANICAL VENTILATION IN CHRONIC OBSTRUCTIVE LUNG DISEASES WITH ACUTE OR CHRONIC RESPIRATORY FAILURE]

BALIKÓ Zoltán

[Over the past decade, the use of noninvasive ventilation in the setting of acute exacerbations of chronic obstructive pulmonary disease (COPD) has gained popularity, and is recommended by evidence-based guidelines. The evidence that it should be effective in chronic COPD is much weaker, and large, prospective, randomised, controlled studies that would also provide a guide for the selection of the best candidates, are still lacking. It has bee established, however, that home mechanical ventilation is certainly beneficial for a well-defined subgroup of patients. This includes the so called “blue bloater” patients (with hypercapnia and polyglobulia), other cases with increased hypercapnia, and patients with "overlapping" syndrome (COPD accompanied by sleep apnoe). Also, for patients with acute respiratory failure who refuse intratracheal intubation noninvasive mechanical ventilation remains the only choice. The past years have unequivocally proved the superiority of the positive pressure ventilation mode for either short term or long term use.]

[ACTINOMYCOSIS MIMICKING LUNG CANCER]

CSERNI Gábor, BORI Rita, BOROSS Gábor, FRANK Emil, LÓRÁND Katalin, SERÉNYI Péter, LENGYEL Mária, KOVÁCS Károly, HALÁSZ Mátyás

[INTRODUCTION - The mortality of lung cancer is high, but with early diagnosis the disease can often be cured. The differential diagnosis of pulmonary carcinoma is widely diverse. CASE REPORT - In a 53-year-old male patient, who had been successfully treated for pneumonia complicated with thoracic empyema, both a CT scan and bronchoscopy raised the suspicion of a malignant tumour. Brush cytology was inconclusive; it raised the possibility of malignancy but was not felt diagnostic of a malignant process, whereas biopsy revealed only inflammatory changes. After right lower lobectomy, actinomycosis was diagnosed by histology. This case is used in the paper as an opportunity to discuss the pseudotumorous presentation of thoracic actinomycosis. CONCLUSION - Pulmonary and thoracic actinomycosis is rare, but due to its ability to simulate tumours, it is an important disease to consider in the differential diagnosis of lung cancer.]

[THE POTENTIAL ROLE OF THE SEMICARBAZIDESENSITIVE AMINE OXIDASE ACTIVITY IN THE DEVELOPMENT OF DIABETIC RETINOPATHY]

DURA Eszter

[Recent data suggest that the copper-containing semicarbazide-sensitive amine oxidase enzyme (SSAO) may play a role in vascular endothelial damage through conversion of certain endogenous monoamines, such as methylamine, into cytotoxic aldehydes, hydrogen peroxide and ammonia. SSAO is present in various human tissues and in the serum. Elevated SSAO activities have been reported in patients with both types of diabetes mellitus. We have demonstrated that the activity of serum SSAO is significantly higher in type 2 diabetic patients with high-risk proliferative diabetic retinopathy compared to those without retinopathy. Our clinical results support the hypothesis that elevated SSAO activity may be involved in the pathogenesis of microvascular diabetic late complications, such as retinopathy. The enzymatic conversion of the endogenous monoamines (e.g. methylamine, aminoacetone) into toxic aldehydes and hydrogenperoxide may be one of the possible mechanisms of the development of microangiopathy. Also, the vascular adhesion protein-1 (VAP-1) function of the molecule can cause leukostasis and leukocyte activation through increased leukocyte adhesion, resulting in worsening of the capillary circulation and hypoxia. Further prospective, larger studies are needed to elucidate the role of the possible association between serum SSAO activity and highrisk proliferative retinopathy in patients with type 2 diabetes. The pharmacological manipulation of SSAO activity might be an interesting new concept for prevention and treatment of diabetic retinopathy.]

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.

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias

BALÁZS Nóra , BERECZKI Dániel, KOVÁCS Tibor

In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

[Is the implementation of Vojta therapy associated with faster gross motor development in children with cerebral palsy? ]

SANZ-MENGIBAR Jose Manuel , MENENDEZ-PARDIÑAS Monica , SANTONJA-MEDINA Fernando

[Vojta therapy has been reported as clinically beneficial for strength, movement and gross motor activities in individual cases and is being included within the second of three levels of evidence in interventions for cerebral palsy. The goal of this study is to understand the effect of Vojta therapy on the gross motor function. Our clinical trial followed a one group, pre-post design to quantify rates of changes in GMFM-88 after a two-months period undergoing Vojta therapy. A total of 16 patients were recruited. Post-intervention acceleration rates of GMFM-88-items acquisition (0.005; p<0.001) and Locomotor Stages (1.063; p<0.0001) increased significatively following Vojta the­rapy intervention. In this study, Vojta therapy has shown to accelerate the acquisition of GMFM-88-items and Loco­motor Stages in children with cerebral palsy younger than 18 months. Because functional training was not utilised, and other non-Vojta therapy intervention did not influence the outcome, Vojta therapy seems to activate the postural control required to achieve uncompleted GMFM-88-items. ]

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]
