Lege Artis Medicinae - 2002;12(02)

[There has been increasing expectation in hormone replacement therapy (HRT) as a potentially useful preventive intervention. Observational studies indicated 50% relative risk reduction on ischaemic heart disease among current HRT users. Unfortunately, this has not been justified by the results of the large scale, prospective, placebo controlled, double blind secondary prevention trials. Even these trials underscored the potential adverse effects of hormone replacement therapy (thromboembolic complications, gall bladder disease). No results of completed primary prevention trials are available for the moment. Based on these data the AHA/ACC Science Advisory of 2001 recommends: HRT should not be recommended for secondary prevention There are insufficient data to suggest that HRT should be initiated for the sole purpose of primary prevention of cardiovascular diseases.]

[Recurrent meningitis caused by spontaneous liquorrhoea]

TÓTH Géza, FŰTŐ László, SASHALMI Sándor, KISSÍK Imre, HOMONNAI Andrea, KIS Zsuzsanna, KORDÁS Marianna, CZIRJÁK Sándor

[INTRODUCTION - The most common and most important cause of recurrent meningitis is bacterial infection. In the majority of cases, recurrent episodes of bacterial meningitis are associated with certain anatomical abnormalities that enable bacteria to penetrate subarachnoideal space. Nasal liquorrhoea can arise via traumatic or non-traumatic way. Non-traumatic nasal liquorrhoea with normal pressure is either of congenital origin or "idiopathic" and is frequently called spontaneous liquorrhoea. Spontaneous liquorrhoea is a rare entity making up 3-4 % of nasal liquorrhoea. CASE REPORT - The patient presented in this study was initially treated with purulent meningitis. A diagnosis of Streptococcus pneumoniae infection was established by bacterial culture tests. After being discharged, the patient was free from complaints for a considerable period of time. Her recurrent symptoms of a running nose were diagnosed later as allergic rhinitis at an ambulatory examination. A year later the patient was readmitted to hospital with bacterial meningitis. Due to the noticeable rhinorrhea on admission, the initially suspected liquorrhoea was confirmed by an otorhinolaryngological examination. A CT scan of the cranium verified external and internal pneumocephalus. Through a nuclear medicine examination a liquor fistula communicating with the sphenoidal sinus was diagnosed. After recovering from the meningitis caused by ascending bacterial infection the patient successfully underwent a neurosurgical operation for a reconstruction of the cerebral base via frontal craniotomy. CONCLUSION - With this case presentation we wish to bring attention to the rare disorder of spontaneous cerebrospinal fluid rhinorrhea when treating recurrent meningitis.]

Hyperhomocysteinemia in female migraineurs of childbearing ages

ALEMDAR Murat, SELEKLER Macit Hamit

Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Stroke incidence and prevalence in the world]

KÉKES Ede

[The incidence and prevalence of ischaemic and haemorrhagic stroke declined continuously from 1970 to 2010. The rate of incidence was the lowest in North America, within Europe in the Mediterranean countries, France and in Asian developed countries. The incidence and prevalence the progress of age have in - creased respectively. The outcome of haemorrhagic stroke is worse everywhere, than that of ischaemic form, rate of mortality/incidence is greater.]

[Stroke is the third most frequent cause of death and the most important cause of disability and dependency worldwide. There are marked differences in the incidence, prevalence and mortality between the populations of Eastern and Western Europe. In Hungary, between 1998-2003, the incidence of stroke was 1,5-2 times higher than in the Western part of the continent. The early recognition of signs and symptoms of TIA and stroke and the urgent transportation of the patient to neurology, preferably to the nearest stroke-center are the key points of successful treatment, reduction of consequences and increased survival. The “time is brain” concept means that the management of TIA/stroke patients should be considered as emergency. This review briefly summarizes the epidemiology, key elements of the etiology, risk factors, up-to-dated diagnosis, primary and secondary prevention and treatment of TIA/stroke to provide information regarding the development of this field targeting the optimal management of TIA/stroke patients.]

Is isolated hand weakness associated with subtypes of stroke?

YILDIRIM Ahmet, GÜNGEN Dogan Belma

Background and aim - Isolated hand weakness is an uncommon condition in stroke patients. It is frequently confused with peripheral nerve system (PNS) pathologies; misdiagnosis may delay identification of the etiology and treatment of stroke. Herein, we aimed to underline the necessity of keeping the diagnosis of stroke in mind in case of patients with isolated hand weakness and to assess the etiology of stroke. Materials and methods - A total of eight patients (four females and four males), who are presented with isolated hand weakness and had acute cortical infarction documented via cranial MRI, were enrolled in the study. Demographic characteristics, physical and radiological findings of the patients, as well as the lateralization and etiology of infarction were evaluated. Results - The mean age of the patients was 61.8 ± 12 years. Isolated hand weakness was in the dominant hand in four patients. According to the etiology and clinical signs, the stroke was cardioembolic in three patients and they had predominant radial-side (thumb and index) finger weakness. Large vessel atherosclerosis was present in three patients; two patients with predominant ulnar-side (little and ring) finger weakness and one patient with uniform finger weakness; there were two patients with stroke of undetermined etiology and they had uniform finger weakness. Conclusion - Keeping stroke in mind together with PNS pathologies in case of isolated hand weakness is critical for early diagnosis and treatment of the patients. In addition, cardioembolic focus should be considered in case of predominant radial-side finger weakness, whereas particular attention should be paid to carotid artery diseases in case of predominant ulnar-side finger weakness.

[Evidence-based practice guidelines for nursing and rehabilitation of stroke patients]

BALOGH Zoltán

[Stroke is a common problem, being the third most frequent cause of death in the United Kingdom and Hungary, accounting for about 20% of bed occupancy. It is also an important cause of morbidity and disability mainly for those aged over 65. As a result, stroke care constitutes as an important part of health services use. Home care services working in the field of stroke rehabilitation have not used a unified evidence-based approach and well-described professional principles and protocols. There was little cooperation between the teams working in the institutional rehabilitation and home care rehabilitation services. No agreed rehabilitation processes, and standardised scales and documentation, showing the change of quality of life, were in use. There were no quality indicators and efficiency measures of nursing and no provision of services either. The Hungarian Nursing Association played a pioneering role in the introduction and dissemination of Evidence Based Nursing in Hungary and in adopting it into routine clinical practice. The successful implementation of the Association's project could be a good example for another field of care and nursing in Hungary and other countries in Europe. Our projects are supported by the Department For International Development (UK) in the framework of the TUDOR project. The Hungarian Nursing Association (HNA) developed a postgraduate training programme entitled "Evidence based nursing in practice". The participants were required to be members of the HNA, have a degree in the field of nursing (nurse teacher, degree nurse, nurse director). Members of the target group were all working in the field of stroke rehabilitation at hospitals or out-patient clinics and home nursing. The Hungarian Nursing Association's professional group developed an evidence based practice guideline for rehabilitation of stroke patients, which was published in the Bulletin of the Ministry of Health (11/2002, 23rd May, 2002). These evidence-based stroke rehabilitation guidelines focused on bladder management, position therapy and patient information.]
