[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]

[CADASIL and other hereditary small vessel diseases of the brain - Increasingly diagnosed conditions underlying familial ischaemic stroke and dementia]

GUNDA Bence, HUGUES Chabriat, BERECZKI Dániel

[CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) has recently gained great interest in vascular neurology as the most common heritable cause of stroke and vascular dementia in adults. This autosomal dominant small vessel disease of the brain - unlike the sporadic, hypertensive form - appears already in adult midlife in the absence of vascular risk factors with ischemic episodes and progressive dementia, its first manifestation can be migraine with aura, and is often associated with psychiatric disturbances. The magnetic resonance imaging (MRI) changes showing a characteristic pattern may precede symptoms by more than a decade. The identification of the mautation of the NOTCH 3 gene responsible for the disorder encoding a transmembrane receptor of vascular smooth muscle cells - has given great impetus on research to understand the molecular and vascular pathogenesis of the disease. The special importance of this latter lies in the fact that CADASIL provides a pure genetic model for subcortical cerebral ischemia and vascular dementia without the confounding factors of comorbidities and advanced age. Thus insights into CADASIL may help us better understand the more common sporadic forms as well. Moreover CADASIL is one of the best studied examples of secondary migraine. Currently we have far less knowledge on other forms of hereditary small vessel disease of the brain such as CARASIL, HERNS, CRV, HVR, PXE etc. Neurologists are becoming more and more familiar with CADASIL, and with the wider availability of MRI it is increasingly diagnosed. However the disorder is still probably underrecognised. This review aims to summarize our current knowledge on CADASIL with special emphasis on diagnostic and diffrential diagnostic points for the practising neurologist.]

[EEG source localization using LORETA (Low Resolution Electromagnetic Tomography)]

PUSKÁS Szilvia

[Electroencephalography (EEG) has excellent temporal resolution, but the spatial resolution is poor. Different source localization methods exist to solve the so-called inverse problem, thus increasing the accuracy of spatial localization. This paper provides an overview of the history of source localization and the main categories of techniques are discussed. LORETA (Low Resolution Electromagnetic Tomography) is introduced in details: technical informations are discussed and localization properties of LORETA method are compared to other inverse solutions. Validation of the method with different imaging techniques is also discussed. This paper reviews several publications using LORETA both in healthy persons and persons with different neurological and psychiatric diseases. Finally future possible applications are discussed.]

Acute bilateral drop foot as a complication of prolonged squatting due to haemorrhoid

KOKSAL Ayhan, DOGAN Burcu Vasfiye

Drop foot is defined as difficulty of dorsiflexion of the foot and ankle due to weak anterior tibial, extensor hallucis longus and extensor digitorum longus muscles. Cauda equina syndrome, local peroneal nerve damage due to trauma, nerve entrapment, compartment syndrome and tumors are common etiologies. A 32-year-old male patient was applied with difficulty in dorsiflexion of both of his toes, feet and ankles after he had squatted in toilette for 6-7 hours (because of his haemorrhoid) after intense alcohol intake 2 weeks before. Acute, partial, demyelinating lesion in head of fibula segment of peroneal nerves was diagnosed by electromyography. This case was reported since prolonged squatting is an extremely rare cause of acute bilateral peroneal neuropathy. This type of neuropathy is mostly demyelination and has good prognosis with physical therapy and mechanical devices, but surgical intervention may be required due to axonal damage. People such as workers and farmers working in the squatting position for long hours should be advised to change their position as soon as the compression symptoms (numbness, tingling) appear.

[MEDICINAL HERBS IN THE TREATMENT OF LIVER DISEASES]

SCHULLER János

[Today, alternative medicine is increasingly popular among patients. Patients with liver diseases surprisingly often use complementary treatment, mainly medicinal herbs, with or without the knowledge of their physician. This is one of the reasons why doctors may not ignore alternative medicine. Another reason is that twenty to thirty percent of medicaments now used in conventional therapy were originally produced from herbs. This means that some of the herbal medicines now applied in alternative therapy may become a conventional drug in the future. This paper reviews publications of evidencebased medicine on herbal medicines most often used in the treatment of liver diseases, including silymarin, glycyrrhizin, phyllantus amarus, CH- 100, LIV.52, sho-saiko-to, bin-gan, compund 861 and oxymatrine. It is important for physicians to be also knowledgeable about potentially hepatotoxic medicinal herbs.]

[What does a triage nurse do? ]

BALOGH Khernné Mariann

[Emergency patient care department problems have recently come to the fore, especially in terms of waiting times and triage activity. It is still not entirely clear to society what is the triage system is, what is it good for, and who is the person, who applies the classification of patients. There is countless conflicts and tensions in the process of health services due to lack of knowledge. In Hungary, emergency departments play a prominent role in healthcare. Increased patient flow is a global problem, and therefore a distinction should be made between the „door to physician time” of the patients. The so-called grading system (triage) has been developed for this purpose, during which an experienced qualified nurse will measure and assess the patient’s condition as quickly as possible on the basis of different criteria. In my communication, I present the triage activity, the use of the classification system, what the triage nurse is doing, by comparing two cases. ]

[The value of multislice computed tomography in the diagnosis of pulmonary embolism and in differential diagnostics]

BODROGI Nándor, BARANYAI Tibor

[INTRODUCTION - The multislice CT (MSCT) pulmonary angiography has been used increasingly in the diagnosis of pulmonary embolism with worldwide application and nowadays it can be considered as a gold standard technique. At the author's department a single slice CT has been used from 1993 and a 10 slice CT system with 24 detector-lines was installed in 2004. The authors summarize the advantages of MSCT in the diagnosis and differential diagnosis of pulmonary embolism and its role in the follow-up of cases and the significant increase of the diagnostic safety. PATIENTS AND METHODS - 2576 chest MSCT examinations were performed between 16 February 2004 and 20 June 2005. In 261 cases pulmonary MSCT angiography was made due to suspected pulmonary embolism. In 7 cases the indication of the CT was different, but due to the findings (pulmonary embolism) this group of patients is discussed in this paper. 268 cases were evaluated retrospectively. In 12 patients, CT could not be performed due to contrast agent allergy or because of seriously impaired renal function. In 2 cases it was not possible to establish a venous access. The therapeutical result was monitored upon the request of the clinicians. The pulmonary MSCT angiography was performed in accordance with a detailed acquisition and reconstruction protocol. In the reprocessing stage the 2D (MPR) reconstruction in different directions was an important step. In addition, three-dimensional MIP was used and VRT reconstruction was also made, if needed. Bolus tracking was applied in order to achieve a good contrast phase. RESULTS - In 116 out of 268 cases pulmonary embolism was detected by pulmonary MSCT angiography. In 7 patients pulmonary embolism was not the primary diagnosis. Pathological changes could not be detected in 55 cases (20.5%) and embolism was not proven later in these patients. No false negative study was recognized. In one case, after the death of the patient the autopsy failed to prove the presence of pulmonary embolism, this represents one false positive diagnosis. In 97 patients pulmonary embolism was not detected, however other findings were found relating to the complains of the patients and thus proper therapy could be introduced. CONCLUSION - Pulmonary MSCT angiography proved to be a highly accurate method for the diagnosis and for exclusion of pulmonary embolism and also in the evaluation of its extent. MSCT can be used in monitoring the result of the therapy. In addition, MSCT gives an opportunity to detect other acute pathological conditions of the chest, thus value of the study is significant in the differential diagnosis.]

[Committed physicians, emotional resonance for a better physician-patient relationship]

LAZÁNYI Kornélia, SZLUHA Kornélia

[With the advent of holistic medicine in the second half of the 20th century, the range of behavioural patterns that are expected from healthcare workers has also changed. Nowadays, numerous references in literature put emphasis on the potential positive impact of personal interactions between physician and patient on the healing process and overall well-being of patients. However, it does not come naturally to all workers with caring professions to seek personal interactions with their patients or display appropriate emotions. Some will have to make deliberate efforts, perform emotional labour, to achieve that goal. A healthcare worker’s commitment to healing and caring may make it easier for him/her to perform emotional labour. Emotional labour and commitment of 84 healthcare workers involved in oncology, and organizational factors with impact thereupon, were studied to explore the potential relationship between commitment and emotional labour. PANAS-X questionnaires were used to quantify emotional labour, while commitment and influencing factors were surveyed by means of explicative questions. Our findings confirmed a correlation between commitment and genuine acting as corroborated by literaure data. It was demonstrated that committed healthcare workers’ spontaneous emotions were more in compliance with what their patients expected them to display, and even their behavioural patterns were more in tune with the patients’ expectations. Confirmation as an organizational factor and colleague/ patient attitudes were found to have the strongest impact on commitment. It is essential that selection criteria for healthcare workers include examination for an altruistic caring attitude. Even more importantly, operators and managers of healthcare institutes should make efforts to create a good working environment and offer regular confirmative feedbacks for improved commitment by their employees.]
