[MODERN PRINCIPLES OF EARLY DETECTION, DIAGNOSIS AND TREATMENT IN LUNG CANCER]

OSTOROS Gyula, KOVÁCS GÁBOR, BÖSZÖRMÉNYI Nagy György, STRAUSZ János

[New clinical guidelines for the diagnosis and treatment of lung cancer contain important advancements. It is necessary therefore that these novelties are widely known by health care professionals. With an existing X-ray screening network in Hungary, we have a unique chance to discover lung malignancies in an early stage in the population. Annual screening is recommended in risk groups over 40 years of age using a nation wide established digital screening network technology. In the therapy of small cell lung cancer there has been no major advance in the past ten years. However, by today, the number of small cell lung cancer patients represent only about 15% of all lung cancer cases. There have been advancements in other fields of the therapy of non small cell lung cancer. Third generation cytotoxic agents used in a platinum based chemotherapy protocol improved quality of life, response rate and survival time. Radiochemotherapy used in locally advanced stages also represented a step forward. In early stage of non small cell lung cancer it has been revealed that significantly improved survival time can be reached with adjuvant combined cytotoxic chemotherapy. Based on these results adjuvant chemotherapy became part of the therapeutic protocol. The use of molecular targeted chemotherapy in the clinical practice of non small cell lung cancer treatment is also a novelty. New therapeutic approaches are epidermal growth factor inhibitors, angiogenesis inhibitors, antivascular, signal transduction modifiers, apoptosis inducing, eicosanoid signal transduction modifiers and immunotherapeutic drugs. Placebo controlled trials have proved the effectiveness of the epidermal growth factor tyrosine kinase inhibitor erlotinib in the second and third line therapy of non small cell lung cancer and can be administered in the European Union in this indication. The improvement in the complex care of lung cancer patients in Hungary is characterized by the gradual increase in the prevalence data, meaning the gradual increase of the number of lung cancer patients still alive.]

[A RARE CAUSE OF CYANOSIS - A CASE REPORT ON SULFHEMOGLOBINEMIA]

HARANGI Mariann, MÁTYUS János, NAGY Erzsébet, NAGY Emőke, PARAGH György, BALLA József, OLÁH V. Anna

[INTRODUCTION - Sulfhemoglobinemia (SHb) is an uncommon cause of cyanosis that is predominantly caused by drugs in adults. CLINICAL CASE - We report on an unusual case of sodium sulfate induced sulfhemoglobinemia in a 61-year-old woman after surgical polypectomy. Fractional hemoglobin derivates were assayed by spectrophotometry and high-performance liquid chromatography (HPLC). The sulfhemoglobinemia ratio was 8.6% in the first sample, and 3.77% a month later measured by spectrophotometry. In the hemolysate a new peak was identified as sulfhemoglobinemia by HPLC. It showed the presence of 9.37% sulfhemoglobinemia in the first sample and 4.88% a month later. After omitting the suspected toxic agent the cyanosis decreased significantly. CONCLUSIONS - The findings underline the importance of routine sulfhemoglobinemia analysis in cases of cyanosis of unknown origin.]

[THE ROLE OF THE CONSUMPTION OF HOT FOOD AND DRINK IN THE DEVELOPMENT OF OESOPHAGEAL SQUAMOUS CELL CARCINOMA]

SZÁNTÓ Imre, ENDER Ferenc, BANAI János, ALTORJAY Áron, SELI Artúr, FARSANG Zoltán, VÖRÖS Attila

[INTRODUCTION - Potential risk factors leading to the development of squamous cell carcinoma in the oesophagus have been analyzed and summarized in a number of epidemiological studies. Authors disagree as to the pathogenic significance of the individual risk factors in various populations. However, it is commonly accepted that alcohol abuse and smoking play a significant role in the development of this disease. Several reports have suggested a positive relationship between oesophageal squamous cell carcinoma and the consumption of hot food and drink. A recent publication, however, claims that the consumption of hot drink is not a pathogenic factor in itself. In our study we wished either to confirm or to rule out a positive relationship between the development of oesophageal squamous cell carcinoma and the history of consuming hot food or drink. PATIENTS AND METHODS - During the study period (1 January, 1993 - 31 September, 2004) 449 patients with oesophageal squamous cell carcinoma were examined in our endoscopy laboratory. Histories were taken according to a predefined scheme. The aim was to identify patients with a history of consuming hot food or drink and to determine their percentage within the study population. A group of 738 patients examined endoscopically for indications other than oesophageal cancer served as controls. RESULTS - In the control group a significantly higher proportion of patients tended to consume hot food or drink compared to patients with cancer. Among the patients with oesophageal tumour who consumed hot food or drink a higher proportion was addicted to smoking and alcohol compared to the control group. CONCLUSIONS - In our study population we failed to identify a positive relationship between the development of squamous cell carcinoma in the oesophagus and the habit of consuming hot food or drink. We suggest that consumption of hot food or drink may play some role in the development of oesophageal cancer if it is associated with simultaneous smoking and alcohol consumption.]

[Introduction - Stroke is the third leading cause of death worldwide (following cardiovascular and cancer mortality) and associated with serious disability for the vast majority of patients. There is no salvage therapy for irreversibly damaged brain areas, improving the circulation of the surrounding hypoperfused territories may be associated with benefitial clinical states. Cerebral hypoperfusion may play a role in the pathogenesis of other kind of neurological diseases, improvement of global circulation may have a preventive effect on these conditions. Aims - The aim of our study was to review the experimental and clinical articles focusing on the role of vinpocetin in different neurological conditions. Results - Vinpocetin appears to have several different mechanisms of action that allow for its antiinflammatory, antioxidant, vasodilating, antiepileptic and neuroprotective activities in experimental conditions. On the other hand, several meta-analysis of the existing studies in acute stroke examining short and long term fatality rates with vinpocetin was unable to assess efficacy. In chronic cerebrovascular patients, vinpocetin improves impaired hemorheological variables, has significant vasodilating properties, improves endothelial dysfunction, neuroimaging studies showed selective increase in cerebral blood flow and cerebral metabolic rate, all of which are potentially beneficial in cerebrovascular disease and may improve cognitive functions. Summary - Based on the above mentioned results vinpocetin plays an important role both in basic research and in clinical management of different neurological diseases.]

[Meningioma and pregnancy]

BENCZE János, VARKOLY Gréta, HORTOBÁGYI Tibor

[Meningiomas are one of the most frequent primary intracranial tumours, representing one-third of all intracranialneoplasms. The vast majority of meningiomas are histologically benign, but recurrence and progression is quite frequent. They occur usually between the 6th and 7th decade, the female/male ratio is 3:2. Although rare in pregnancy, when occurring, they can cause serious, life-threatening complications due to rapid growth and unfavourable localisation. There are two dominant hypothesis explaining rapid growth in pregnancy: the role of hormonal effects and hemodynamic changes. Several studies tested these theories but none provided unequivocal answer probably because the pathomechanism is complex and multifactorial. We provide an overview of the pathomechanism of meningiomas in pregnancy with emphasis on data obtained by advanced neuropathological, molecular biological, bioinformatic, imaging and epidemiological methods. A better understanding of the processes leading to meningioma development and growth in pregnancy will help us to design personalized therapy and reduce morbidity and mortality.]

[Is there a role of triple combination in the therapy of hypertension? - Antihypertensive efficiency of perindopril-amlodipine-indapamide]

PÁLL Dénes, SZÁNTÓ Ildikó, PARAGH György, KATONA Éva

[Blood pressure reduction to target level decreases cardiovascular morbidity and mortality. However, in the vast majority of cases, this can be achieved only with a (multiple) combination regimen. The primary objective of the PAINT (Perindopril- Amlodipine plus Indapamide Combination for Controlled Hypertension Non-intervention Trial) study was to evaluate the efficacy of combination therapy with perindopril, amlodipine, and indapamide in patients who had not reached target blood pressure with their pre-existing therapy. Secondary objectives included the monitoring of metabolic parameters and the number of antihypertensive tablets taken by the subjects. In this subgroup-analysis we involved 126 patients (74 females and 52 males, mean age 59.8±12.5 years) who had a valid 24-hour ambulatory blood pressure monitoring both at baseline and at the end of the 4-months follow-up. At the beginning of the study none of the subjects reached blood pressure target despite taking on average 2.4±1.4 antihypertensive drugs. During the study, the subjects received the combination of amlodipine, perindopril, and indapamide instead of their pre-existing antihypertensive regimen. 24-hour mean systolic blood pressure decreased from 139.2±13.4 mmHg to 126.5±12.9 mmHg (p<0.01), as well as mean diastolic blood pressure from 77.3±11.3 mmHg to 71.1±8.7 mmHg (p<0.01). Heart rate remained unchanged. Blood pressure reduction was statistically significant both during the day and the night. We found significant blood pressure reduction in all hours (10.1-15.4/5.1-7.8 mmHg; p<0.001). Hyperbaric impact decreased from 366.9±251.1 mmHg × hour to 166.2±185.4 mmHg × hour (p<0.01) for systolic blood pressure, and from 112±130.6 mmHg × hour to 41.6±65.6 mmHg × hour (p<0.01) for diastolic blood pressure. We also could observe favourable changes in metabolic parameters, not only in lipids, but also in blood sugar level. The mean number of tablets taken by the subjects increased from 2.4 to 2.9, but this led to a significantly improved control of blood pressure. Triple combinations of state-of-the-art antihypertensive agents - such as of perindopril, amlodipine and indapamide - ensure effective blood pressure control in sufficiently compliant patients.]

[THE IMPORTANCE OF VITAMIN D DEFICIENCY IN PRACTICE]

TAKÁCS István

[The effects of vitamin D in bone health have been known since the 1920s. Recently, it has been proven that its role in the body is much more complex. Activated vitamin D is a steroid hormone that regulates transcription of more than 200 human genes through its receptor that is detectable in almost all types of cells. In contrast to the former conceptions, it can be activated not only in the kidneys; moreover, local 1-α-hydroxylation plays a greater role in its extraskeletal effects. Vitamin D deficiency, currently defined as serum levels of <30 ng/ml, is caused by the lack of ‘effective’ sunlight exposition. Thus, vitamin D deficiency is one of the most frequent deficiencies in the developed world that plays a role not only in the development of skeletal conditions but many other diseases, as well. A low vitamin D level causes a reduced calcium absorption, a higher bone remodelling rate and increased bone loss. It also reduces muscle strength and increases the risk of falling. Normal vitamin D status is required for the effectiveness of drugs for osteoporosis treatment; however vitamin D treatment in itself is not effective in osteoporosis. An increasing number of studies show the benefits of vitamin D supplementation and treatment in extraskeletal conditions. Vitamin D plays an important role in the prevention of several auto-immune diseases, infections, cardiovascular diseases, and cancers. Therefore, all UV-B radiation-deprived adults require an intake of vitamin D to maintain a level of >30 ng/ml. Vitamin D3 treatment is safe. The necessary dose can be reliably approximated by the calculation that an incremental consumption of 100 IU/day raises serum vitamin levels by 1,0 ng/ml. Clinical trials suggest that for the vast majority of individuals, a prolonged intake of 10,000 IU/day does not pose any risk.]

[Depression, anxiety and suicidal behavior. Recognition and care]

RIHMER Zoltán, BLAZSEK Péter, HARGITTAY Csenge, KALABAY László, TORZSA Péter

[Depression and anxiety disorders are major problems both in psychiatric and in general practice because of their frequency and recurring character. Owing to their common complications (suicide, suicide attempts, secondary alcoholism / drug disease, increased cardiovascular and cerebrovascular morbidity and mortality, loss of work, social isolation, etc.) they are the cause of significant individual, family and social burdens. In our paper we review the clinically revealable suicide risk and protective factors that can be observed in depression and anxiety disorders as well as the main aspects of the recognition and care of suicidal patients. With available medicines and non-pharmacological therapies, the vast majority of depressive and anxiety patients can be successfully treated and in most cases we can prevent suicidal behavior associated with these diseases. Besides psychiatrists general practitioners as well play a significant role in preventing suicidal behavior and in the recognition of suicide risk. ]
