Abstract
Background How dental education influences students’ dental and dentofacial esthetic perception has been studied for some time, given the importance of esthetics in dentistry. However, no study before has studied this question in a large sample of students from all grades of dental school. This study sought to fill that gap. The aim was to assess if students’ dentofacial esthetic autoperception and heteroperception are associated with their actual stage of studies (grade) and if autoperception has any effect on heteroperception. Methods Between October 2018 and August 2019, a questionnaire was distributed to 919 dental students of all 5 grades of dental school at all four dental schools in Hungary. The questionnaire consisted of the following parts (see also the supplementary material): 1. Demographic data (3 items), Self-Esthetics I (11 multiple- choice items regarding the respondents’ perception of their own dentofacial esthetics), Self-Esthetics II (6 Likert-type items regarding the respondents’ perception of their own dentofacial esthetics), and Image rating (10 items, 5 images each, of which the respondents have to choose the one they find the most attractive). Both the self-esthetics and the photo rating items were aimed at the assessment of mini- and microesthetic features. Results The response rate was 93.7% (861 students). The self-perception of the respondents was highly favorable, regardless of grade or gender. Grade and heteroperception were significantly associated regarding maxillary midline shift (p < 0.01) and the relative visibility of the arches behind the lips (p < 0.01). Detailed analysis showed a characteristic pattern of preference changes across grades for both esthetic aspects. The third year of studies appeared to be a dividing line in both cases, after which a real preference order was established. Association between autoperception and heteroperception could not be verified for statistical reasons. Conclusion Our findings corroborate the results of most previous studies regarding the effect of dental education on the dentofacial esthetic perception of students. We have shown that the effect can be demonstrated on the grade level, which we attribute to the specific curricular contents. We found no gender effect, which, in the light of the literature, suggests that the gender effect in dentofacial esthetic perception is highly culture dependent. The results allow no conclusion regarding the relation between autoperception and heteroperception.

Abstract
The purpose of this study was to determine whether cherry extract has any effect on salivary α-amylase activity (sAA) or on the level of Streptococcus mutans in human saliva. 70 patients (45 females and 25 males) in three age groups (22 children, 25 young adults, and 23 adults) were examined. All participants completed a questionnaire to obtain information on their oral health behaviour and life style. Clinical examination was performed to record the number of decayed, missing and filled teeth (DMF-T). Saliva samples were collected for the measurement of sAA and the salivary S. mutans level before and after chewing a gum with or without cherry extract. Statistical evaluation of data was performed. S. mutans and the sAA level of unstimulated saliva samples did not depend on either age or gender. The basal sAA value of adult patients was in linear correlation with the dental caries status. Habitual chewing-gum use decreased the resting sAA and the mean of DMF-T. The number of S. mutans cells was significantly lower in the resting saliva of allergic patients. The applied mechanical and gustatory stimuli by chewing gum resulted in higher sAA and S. mutans levels and a slow decrease of values was observed in the control group for the next 30 min. Thereafter, sAA and S. mutans levels decreased earlier in the presence of sour cherry extract than those of control cases. Chewing gum with sour cherry extract may be useful for the prevention of dental caries.

Abstract
Mucositis is the most common oral complication of cancer therapy. Oral mucositis in childhood is more frequent and severe compared to adults, especially in children with leukemia. Lesions develop as the chemotherapeutic agents attack the rapidly dividing cells of the oral mucous membrane. Patients may experience trouble in eating, drinking, swallowing or even speaking due to the significant pain caused by the ulceration of the oral mucosa. Oral mucositis has a direct impact on the quality of life and may affect survival. The regular assessment of the oral mucosa is crucial during chemotherapy to evaluate the effectiveness of the oral mucositis prevention and treatment. Several oral mucositis scoring tools have been developed for adults to qualify the symptoms, but there is no universally accepted assessment scale for children. The prevention and treatment of therapy-related mucositis is difficult, though several methods and pharmacologic agents have been tested. Here we discuss the pathogenesis of chemotherapy-induced oral mucositis, the available assessment tools and their applicability to pediatric patients and the available therapeutic and preventive strategies.

Abstract
Oral squamous cell carcinoma (OSCC) is the seventh most common malignancy and the ninth most frequent cause of cancer death in Europe. Within Europe, Hungary has one of the highest rates of OSCC incidence and mortality. Thus, there is an urgent need to improve early detection. Saliva, as a readily available body fluid, became an increasingly important substance for the detection of biomarkers for many diseases. Different research groups have identified salivary biomarkers specific for OSCC for different countries. In this study, saliva samples of Hungarian patients with OSCC were studied to discover disease‐specific and perhaps region‐specific biomarkers. LC‐mass spectrometry (MS)/MS analysis on a linear ion trap‐Orbitrap mass spectrometer was used for qualitative and quantitative salivary protein profiling. More than 500 proteins were identified from saliva by shotgun proteomics. The up‐ and downregulated proteins in the saliva of patients with OSCC highlighted the importance of protein–protein interaction networks involving the immune system and proteolysis in disease development. Two potential biomarkers from our shotgun analysis and a third candidate reported earlier by a Taiwanese group were further examined by ELISA on a larger reference set of samples. Resistin, a biomarker reported in Taiwan but not validated in our study, highlights the necessity of application of standardized analysis methods in different ethnic or geographical populations to identify biomarkers with sufficient specificity and sensitivity.

Abstract
The purpose of this study is to determine the possible etiological factors of oral squamous cell carcinoma (OSCC) in North-Eastern Hungary. The medical records of 119 randomly selected patients with OSCC admitted to the Department of Maxillofacial Surgery of the Faculty of Dentistry, University of Debrecen were reviewed. The following risk factors were investigated: tobacco and alcohol consumption, dental status, rural vs. urban residence, and high risk HPV infection. The presence of HPV DNA has been evaluated by polymerase chain reaction from the tissue samples. Results were correlated with clinical data. At the time of diagnosis 65.5 percent of the patients were smokers. Under the age of 45 the rate was 86.4%. Smoking significantly correlated with younger age, male gender, advanced clinical stages and alcohol consumption. The majority of the patients (75.5%) consumed alcohol, 41.1% regularly over the acceptable range. Drinking habit significantly correlated with younger age, male gender and tumor site (gingiva, retromolar region, tongue). HR-HPV types were detected in 42.8% of samples tested. HPV DNA presence was not related to gender, clinical stage, histological grade or other risk factors. Authors found weak correlation between HR-HPV positivity, younger patient age and better 5-year survival rate. The dental status was acceptable only in 12.6 percent of the cases. There was a correlation between dental status and age, smoking and drinking habits. No significant urban-rural differences were found. In the study population the most important risk factor for developing oral cancer is tobacco smoking followed by alcohol consumption. Avoidance of tobacco smoking and a reduced amount of alcohol, together with healthy nutrition and regular dental care should be emphasized.

Abstract
The purpose of this study was to characterize the epidemiological data of oral squamous cell carcinoma (OSCC) patients in North-Eastern Hungary. The medical records of 119 randomly selected patients with OSCC admitted to the Department of Maxillofacial Surgery of the Faculty of Dentistry, University of Debrecen were reviewed. Cases were identified according to the epidemiological data, as to site, tumor size, lymph node involvement, clinical stage, histological differentiation, treatment obtained, recurrence of disease and survival rate. There was an obvious male predominance (male:female = 5.2:1). The median age at diagnosis was 57.4 years. The most common sites of OSCC were the floor of the mouth (27.7%), the lip (26.9%) and the tongue (22.7%). The majority of the patients (58,8%) presented with early-stage (I-II) disease at the time of diagnosis, and 48.6% had moderately differentiated tumors. The most frequent therapeutic modality used was surgery with or with out of radiotherapy. Roughly one fifth of the cases (20.7%) experienced a recurrence of disease during the follow-up period. The overall 5-year survival rate was 38.7% (stage I: 68.3%, stage II: 31.0%, stage III: 22.6%, stage IV: 11.1%). There was a correlation between survival and tumor size, lymph node metastasis, clinical stage and surgical treatment (p < or = 0.05, respectively). We found no significant correlation between histological differentiation and survival. Clinical stage exerts the most strongly significant impact on survival. Therefore, early detection and proper surgical intervention enhance patients' survival most effectively.

Abstract
Hypodontia is one of the most common human dental anomalies. Its management is often complicated. This survey was carried out to study the prevalence, localisation and combination of congenital aplasia in Department of Paediatric Dentistry, Faculty of Dentistry, University of Debrecen. The study group consisted of 669 children, 283 boys and 386 girls, aged 4-18 years. Orthopantomograms and clinical examinations were used for the retrospective study. The prevalence of hypodontia was found to be 7.76 percent, excluding the third molars. Most of the congenitally absent teeth were the upper lateral incisors and the lower second premolars. The most frequent combinations were the 12-22 and the 35-45 ones. We found that our data were very similar to the different international results.

Abstract
Infiltrating osteoporotic cancellous bone with bone cement (vertebroplasty) is a novel surgical procedure to stabilize and prevent osteoporotic vertebral fractures. Short-term clinical and biomechanical results are encouraging; however, so far no reports on long-term results have been published. Our clinical observations suggest that vertebroplasty may induce subsequent fractures in the vertebrae adjacent to the ones augmented. At this point, there is only a limited understanding of what causes these fractures. We have previously hypothesized that adjacent fractures may result from a shift in stiffness and load following rigid augmentation. The purpose of this study is to determine the load shift in a lumbar motion segment following vertebroplasty. A finite-element (FE) model of a lumbar motion segment (L4-L5) was used to quantify and compare the pre- and post-augmentation stiffness and loading (load shift) of the intervertebral (IV) disc adjacent to the augmented vertebra in response to quasi-static compression. The results showed that the rigid cement augmentation underneath the endplates acted as an upright pillar that severely reduced the inward bulge of the endplates of the augmented vertebra. The bulge of the augmented endplate was reduced to 7% of its value before the augmentation, resulting in a stiffening of the IV joint by approximately 17%, and of the whole motion segment by approximately 11%. The IV pressure accordingly increased by approximately 19%, and the inward bulge of the endplate adjacent to the one augmented (L4 inferior) increased considerably, by approximately 17%. This increase of up to 17% in the inward bulge of the endplate adjacent to the one augmented may be the cause of the adjacent fractures.

Abstract
Bone cement infiltration can be effective at mechanically augmenting osteoporotic vertebrae. While most published literature describes the gain in mechanical strength of augmented vertebrae, we report the first measurements of viscoelastic material changes of cancellous bone due to cement infiltration. We infiltrated cancellous core specimen harvested from osteoporotic cadaveric spines with acrylic bone cement. Bone specimen before and after cement infiltration were subjected to identical quasi-static and relaxation loading in confined and free compression. Testing data were fitted to a linear viscoelastic model of compressible material and the model parameters for cement, native cancellous bone, and cancellous bone infiltrated (composite) with cement were identified. The fitting demonstrated that the linear viscoelastic model presented in this paper accurately describes the mechanical behaviour of cement and bone, before and after infiltration. Although the composite specimen did not completely adopt the properties of bulk bone cement, the stiffening of cancellous bone due to cement infiltration is considerable. The composite was, for example, 8.5 times stiffer than native bone. The local stiffening of cancellous bone in patients may alter the load transfer of the augmented motion segment and may be the cause of subsequent fractures in the vertebrae adjacent to the ones infiltrated with cement. The material model and parameters in this paper, together with an adequate finite-element model, can be helpful to investigate the load shift, the mechanism for subsequent fractures, and filling patterns for ideal cement infiltration.

Abstract
Cancer is the second most common cause of mortality in childhood. Complex therapy decreases the rate of mortality, but chemotherapy and irradiation may, however, create acute and long-term side effects. Although immuno- and myelo-suppressive side effects of anti-neoplastic therapy are unavoidable, their detrimental impact on oral health can and should be avoided contributing to a better quality of life of these children.

Abstract
There are many different causes thus many different forms of fear and anxiety. The so called 'dental fear' and 'dental anxiety' are especially significant for the dentists since they determine the attitude of the patients during therapy. Negligence caused by fear and anxiety influence the dental status. The authors investigated the effect of the dental fear and anxiety on the dental status of children aged between 12-14. A significant correlation was found between the level of the fear and anxiety and the number of the untreated or extracted tooth. Children studying well at school had lower level of fear and better dental status. The mother's educational level also influenced the child's fear significantly.

Abstract
There are various factors which influence the oral status, among them the dental fear. Dental anxious individuals are likely to have more missing teeth and fewer filled ones. This study examined the association between dental anxiety and oral health status in parents and indirectly in children. The authors found that there is positive correlation between dental fear and missing teeth in the older generation. These tendency can also be seen in younger ones.

Abstract
It is known from previous studies that hemorheological parameters are altered in patients with essential hypertension. The hemorheological and hemodynamical effects of doxazosin, a selective alpha-1-adrenoreceptor blocker agent, was examined in twenty patients (mean age: 54+/-10 years) with essential hypertension. Hemorheologic (hematocrit, fibrinogen, plasma and whole blood viscosity) and hemodynamic (cardiac output and index, total peripheral resistance) parameters and plasma lipids were determined. The measurements were carried out before the beginning of the treatment, after 1 week and after 12 weeks treatment periods. Besides significant reduction of blood pressure and total peripheral resistance (p < 0.001), a decrease in cholesterol (p < 0.001) and triglyceride (p < 0.01) levels and a beneficial effect on hemorheological parameters was detected. Fibrinogen and plasma viscosity decreased significantly (p < 0.01). Hematocrit value was also lower after one week (p < 0.001), then an increase could be seen. Whole blood viscosity showed similar changes as hematocrit, but the degree of its final increase was slighter, which was supported by the significantly lower value of corrected blood viscosity (p < 0.05).

Abstract
The aim of the study was to assess the reproducibility of recently developed laser fluorescence method for occlusal caries detection in vivo. 71 non-cavitated premolar and molar teeth were examined repeatedly by three dentists using DIAGNOdent (KaVo) instrument. The presence of caries has been established on the classification of Lussi, created on the basis of "in vitro" investigations. The reproducibility of the measurements were expressed in rank correlation of Spearman. The intra- and interexaminer reliability was also determined by Kappa statistics. The Spearman correlation coefficiencies were fairly high (0.738-0.949) The intraobserver and interobserver coincidencies reflected by Kappa values (0.60-0.88 and 0.44-0.77, respectively) were also convincing.

Abstract
BACKGROUND There are several minimally invasive means of exposing the adrenal glands. Each of them has its own advantages and disadvantages. A new approach was introduced for laparoscopic adrenalectomy on the left side. PATIENTS AND METHODS Between June 1997 and January 2000, 23 transperitoneal unilateral laparoscopic adrenalectomies on the left side were performed. In 4 of these cases, only enucleation of a well-circumscribed adenoma was done. In a semilateral position, the gland was approached through the splenophrenic ligament with partial mobilization of the spleen. The left adrenal gland was quickly and safely exposed, thus avoiding the complications of transmesocolic exposure. There was no need for extensive mobilization of the spleen or the pancreas. RESULTS In 20 cases the laparoscopic operation was successfully performed. In 3 cases conversion was necessary because of bleeding. The estimated blood loss was on average 150 ml. The mean operation time was 84 min, the mean postoperative stay 4.5 days. No other major complications were observed. CONCLUSION This new method is a safe and quick technique for left-sided laparoscopic adrenalectomy, and it can be an alternative to the existing ones.

Abstract
In the past decade it became accepted that free radicals, lipid peroxidation and antioxidant defense play a role in various tissues damages, thus in certain liver diseases as well. Since only limited data have been reported concerning the oxidative stress in viral hepatitis, a comparative study was performed in patients (pts) with chronic hepatitis C and alcoholic liver disease. In addition, the effects of a flavonolignan drug silymarin were assessed. 10 pts with chronic hepatitis C, 5 pts with alcoholic hepatitis and 13 pts with alcoholic cirrhosis have been investigated. Biochemical liver tests (serum bilirubin, aminotransferases, ALT, AST, lactate dehydrogenase (LDH), pseudocholinesterase, prothrombin), malandialdehyde (MDA) levels in plasma and red blood cell (RBC) hemolysate, superoxide radical generating capacity of stimulated polymorphonuclear granulocytes (PMN), plasma concentrations of reduced (GSH) and oxidized (GSSG) glutathione, vitamin A, luteine and beta carotene, furthermore RBC superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase activities were determined. The level of plasma MDA--as the marker of lipid peroxidation--was highest in alcoholic cirrhosis (five times of normal) (p < 0.05), the RBC hemolysate MDA was most elevated in chronic hepatitis C (p < 0.05). The mean PMNs' superoxide radical generating capacity was 116.6% of normal control in alcoholic hepatitis, where the mean GSH level was the lowest (89.8% of normal). Plasma vitamin A content was lowest in alcoholic cirrhosis (68% of control) (p < 0.05). SOD activity was elevated in both chronic hepatitis C and alcoholic cirrhosis, where GPx activity was decreased (p < 0.05). There was a correlation between LDH and SOD activities (r = 0.77, p = 0.015). Silymarin treatment of one month duration resulted in normalization of serum bilirubin in 55% of treated pts, AST became normal in 45%, and RBC hemolyzate MDA level normalized in similar rate. A significant increase in both GSH and retinoids was found. Alterations in oxidative stress and antioxidant defense system were shown in chronic hepatitis C, not only in alcoholic liver disease. The parameters of lipid peroxidation and antioxidant defense may be useful surrogate markers for monitoring pts with liver disease during hepatoprotective treatment.

Abstract
Hemorheological factors play an important role in the pathogenesis of different cardiovascular diseases. The hemorheological and hemodynamic parameters in essential hypertension and their possible modification by antihypertensive treatment were examined in the following two studies. In the first study the fundus appearance and hemorheological parameters (plasma and whole blood viscosity (WBV), fibrinogen level) of 33 hypertensive patients (mean age: 55 years) were examined. The fundus appearance showed retinopathy in all the cases between stages I-III. All the measured hemorheological parameters of the examined patients were in the pathological range (WBV at 90 s(-1): 5.18 mPa s) and were significantly (p < 0.01) higher than in healthy controls (WBV at 90 s(-1): 4.18 mPa s). The hemorheological factors showed a parallel deterioration with the fundus appearance, namely their values were significantly (p < 0.01) higher in patients with a fundus appearance stage III (WBV at 90 s(-1): 6.02 mPa s) than stage I (WBV at 90 s(-1): 4.51 mPa s). These results show that there is a correlation between hemorheological parameters and fundus appearance in hypertensives, and this suggests that hemorheological factors may play a role in the development of hypertensive retinopathy. In the second study the hemorheological and hemodynamical effects of Doxazosin, a selective alpha-1-adrenoreceptor blocker agent, was examined in twenty patients (mean age: 54 years) with essential hypertension. Hemorheologic (hematocrit, fibrinogen, plasma and whole blood viscosity) and hemodynamic (cardiac output and index, total peripheral resistance) parameters and plasma lipids were determined. The measurements were carried out before the beginning of the treatment, after 1 week and after 12 weeks treatment periods. Besides significant reduction of blood pressure and total peripheral resistance (p < 0.001), a decrease in cholesterol (p < 0.001) and triglycerides (p < 0.01) levels and a beneficial effect on hemorheological parameters was detected. Fibrinogen and plasma viscosity decreased significantly (p < 0.01). Hematocrit value was also lower after one week (p < 0.001), then an increase could be seen. Whole blood viscosity showed similar changes as hematocrit, but the degree of its final increase was slighter, which was supported by the significantly lower value of corrected blood viscosity (p < 0.05). All these findings indicate that hemorheological factors may play a role in the pathogenesis and in the development of organ damages in hypertension.

Abstract
Between July 1997, and April 1999 the authors performed 25 transperitoneal laparoscopic adrenalectomies. Conversion due to bleeding in 3 cases and due to unsuspected malignancy in 1 case was necessary. Complete resection was carried out in 22 cases. In 3 cases where a well circumscribed adenoma was visualized, only enucleation was performed. A new approach for left sided resection was also introduced. In the authors experience laparoscopy is an absolutely suitable intervention for the benign diseases of the adrenal glands. It assures a short, uncomplicated and painless postoperative period for the patients, with the same effectivity and safety compared to the conventional method.

Abstract
The role of salivary immunoglobulins (IgA, IgM, IgG) in caries etiology is not yet clearly known. Our aim was to study whether there might be a connection between the amount of immunoglobulins in the saliva and caries prevalence. It was found that there was a significant difference (p < 0.05 or less) in secretory IgA, IgM, IgG levels, as well as DMF-T, DMF-S (approx) indices between selective IgA deficient, hypogammaglobulinemic, and healthy children, who had primary teeth.

Abstract
Infection of macrophages with human cytomegalovirus (HCMV) has been shown to be nonlytic and exclusively cell associated. Human T cell leukemia-lymphoma virus type I (HTLV-I) is capable of establishing productive infection in macrophages. We studied the interactions between HCMV and HTLV-I in monocyte-derived macrophages cultured in vitro. We found that coinfection of macrophages with HCMV and HTLV-I significantly enhanced HCMV replication, resulting in release of infectious HCMV from dually infected cells. On the other hand, HCMV inhibited HTLV-I replication in macrophages coinfected with both viruses. Reciprocal interactions between HCMV and HTLV-I were mediated by their trans-acting proteins. Results of transfection studies demonstrated that the tax gene product of HTLV-I alone was capable of upregulating HCMV production. In a transient gene expression assay the immediate-early 2 (IE2) protein of HCMV alone could inhibit HTLV-I replication, whereas the IE1 protein, which had no effect by itself, produced a synergistic inhibitory effect together with the IE2 protein. Results from this study suggest that in vivo double infection of macrophages with HCMV and HTLV-I may contribute to the dissemination of HCMV infection in patients suffering from HTLV-I-associated T cell leukemia-lymphoma.

Abstract
The pathological increase of oxygen free radical generation has already been recognised in more than one hundred diseases. To gain information about the consequences of oxidative stress the investigation of plasma antioxidants seems to be plausible. In our study we used a new kit (RANDOX, England) for measurement of total antioxidant status (TAS) to determine whether it has diagnostic value in comparison with our earlier results of measuring other parameters of oxidative stress in the following diseases: i./In the group of patients with ischemic heart disease (n = 19) the TAS elevated from 1.08 +/- 0.13 to 1.16 +/- 0.11 mM after 2 weeks of cardioprotective drug administration showing the beneficial effect of drug treatment. ii./In the group of patients with essential hypertension (n = 47) its values were below the normal range (1.11 +/- 0.15 mM) at the time of the first investigation and increased gradually following antihypertensive treatment. iii./The changes of TAS values of patients who underwent open (n = 21) or laparoscopic (n = 21) cholecystectomy indicated the less surgical trauma following laparoscopic procedures. Our results suggest that determination of TAS is a valuable and reproducible method to detect the actual antioxidant status in patients.

Abstract
OBJECTIVE To study the mechanism of the complement-mediated antibody-dependent enhancement (C'-ADE) of HIV infection which may play a significant role in the progression of HIV-disease. METHODS In vitro complement activating and complement-mediated HIV-infection enhancing abilities of three human anti-gp41 monoclonal antibodies (MAb) were tested. C'-ADE was estimated using HIV-1IIIB and CR2 (CD21)-carrying MT-4 target cells. Normal human serum (NHS), purified C1q, C1q-deficient (C1qD) and C2-deficient (C2D) human sera were applied as complement sources. RESULTS All MAb mediated increased C1q binding to solid-phase gp41. All MAb had a marked dose-dependent and strictly complement-mediated HIV-infection enhancing effect. Mixtures of the MAb with purified C1q also significantly increased HIV-1 infection. C1qD serum had a markedly lower enhancing effect than NHS, which could be raised to normal level by addition of purified C1q. Pretreatment of the target cells with anti-CR2 antibodies only partially inhibited the enhancing effect of the MAb plus normal human serum. CONCLUSION These novel findings indicate that besides the well-known facilitation of entry of HIV-1 by the interaction between virus-bound C3 fragments and CR2 present on the target cells, fixation of C1q to intact virions also results in an enhanced productive HIV-1 infection in the MT-4 cell cultures.

Abstract
The possible effects of TRH administration on different parameters of gastric function were studied in 10 patients with different gastrointestinal complaints. Basal (BAO) and pentagastrin stimulated (6 micrograms pentagastrin/kg bw sc) maximal (MAO) acid output were determined and serum levels of TSH, total and free thyroxine (T4 and FT4), triiodothyronine (T3) were measured. After determinations of BAO and MAO and the hormones indicated above, one group of patients received a TRH injection (0.2 mg protirelin) intravenously. The second group of patients was injected with atropine (atropinum sulfuricum, 1 mg, iv). At different times following the injections in both groups of patients BAO, MAO and serum levels of TSH, total and free T4, T3, gastrin were determined. Injection of TRH resulted in an increase in TSH and with some delay in thyroxine and gastric acid levels. Atropine treatment was followed by a decrease in gastric acid secretion and a small decrease in TSH and no changes in the values of the other studied hormones. The results suggest a complex interrelationship between TRH, vagal system and pentagastrin-dependent gastric acid secretion operating in human subjects.

Abstract
Patients with platelet disorders usually bleed into superficial sites such as the skin, mucous membranes, genitourinary tract and gastrointestinal tract caused by thrombocytopenia or thrombocyte dysfunction. Thrombocytopenia is caused by one of three mechanisms-decreased marrow production, increased splenic sequestration, or accelerated destruction of platelets. We report a 9-year-old male patient with thrombocytopenic purpura, dyserythropoetic anaemia, freckles on the skin and nanosomia, resembling Fanconi's (constitutional) anaemia. Although many patients with constitutional anaemia own other bony abnormalities, it was not found in this case. On the other hand, the patient showed enamel hypoplasia. To our knowledge, this association has never been reported before. Laboratory diagnosis, clinical findings, dental abnormalities and treatment are presented in details.

Abstract
Epstein-Barr virus (EBV) and human immunodeficiency virus type 1 (HIV-1), as well as human T-cell leukemia-lymphoma virus type I (HTLV-I), may interact in the pathogenesis of human retroviral infections. The placental syncytiotrophoblast layer represents a barrier protecting the fetal compartment from exposure to retroviruses. We studied the interactions of EBV with HIV-1 and HTLV-I in human term syncytiotrophoblast cells to investigate the significance of double infections in transplacental transmission of human retroviruses. We found that syncytiotrophoblast cells could be productively infected with EBV. Dual infection of the cells with EBV and HTLV-I resulted in full replication cycle of otherwise latent HTLV-I. In contrast, the restricted permissiveness of syncytiotrophoblasts for HIV-1 was not influenced by coinfection of the cells with EBV. Infection of syncytiotrophoblast cells with EBV, but not HTLV-I, induced interleukin-2 and interleukin-6 secretion, and augmented secretion occurred on coinfection with both viruses. Coinfection of syncytiotrophoblast cells with EBV and HTLV-I induced tumor necrosis factor-beta and transforming growth factor-beta 1 secretion, but infection with either virus alone did not lead to secretion of these cytokines. Permissive replication cycle of HTLV-I was induced by the EBV immediate-early gene product Zta. Pseudotype formation between EBV and HTLV-I in coinfected syncytiotrophoblast cells was not found. Our data suggest that activation of HTLV-I gene expression by EBV in coinfected syncytiotrophoblast cells may be a mechanism for transplacental transmission of HTLV-I.

Abstract
Insoluble glycogen is an enzymatically modified form of naturally occurring soluble glycogen with a great adsorbing capacity. It can be metabolized by phagocytes to glucose. In this study we used insoluble glycogen intravenously in the experimental endotoxin shock of rats. Wistar male rats were sensitized to endotoxin by Pb acetate. The survival of rats were compared in groups of animals endotoxin shock treated and non-treated with insoluble glycogen. Furthermore, we have determined in vitro the binding capacity of insoluble glycogen for endotoxin, tumour necrosis factor alpha, interleukin-1 and secretable phospholipase A2. Use of 10 mg/kg dose of insoluble glycogen could completely prevent the lethality of shock induced by LD50 quantity of endotoxin in rats. All animals treated survived. Insoluble glycogen is a form of ‘metabolizable internal adsorbents’. It can potentially be
used for treatment of septic shock.

Abstract
The aim of present survey was to gain epidemiological data on periodontal condition of 7, 12 and 14 yrs old (40 children in 7, 92 children in 12 and 84 children in 14 yrs old groups) schoolchildren as assessed by the CPITN.

Abstract
A thorough understanding of the incidence, clinical presentation, treatment, prognosis, and psychosocial issues surrounding children with solid tumors enables the nurse to actively participate on the health care team. Although significant advances over the past two-and-a-half decades to improve the outcomes of children with cancer have occurred, there remains room for continued improvement, especially among children with advanced-stage nephroblastoma, neuroblastoma, HCC, and teratoma.

Abstract
The launch of the UKCC's The Scope of Professional Practice and measures to reduce junior doctors' working hours have once again raised debate on what roles are appropriate for nurses. For many, the development of the nurse practitioner role, with its advanced skills and increased levels of autonomy, offers a very desirable template. Much can be learned from the experience of US nurses, and this article describes a relatively recent innovation--the development of the nurse practitioner role in the acute hospital setting. The role is not a physician substitute; rather, it strengthens and promotes a multidisciplinary approach to patient care and presents the nurse with an opportunity to improve the delivery of care provided in the inpatient environment. Most significantly, it remains a nursing role.

Abstract
A WHO survey was carried out earlier on caries prevalence in the 12-year olds. No data are available in the 7- and 14 year old children. The aim of this study was to investigate caries prevalence (DMFT, dmft numbers), percentage of caries free children and treatment needs in these three age-groups. The clinical examination was based on WHO's criteria. DMF numbers were 0,12, 2,11 and 2,51 in 7-, 12- and 14-year old, while dmf numbers were 0,79, 0,51 and 0,05 respectively. Percentage of caries-free children was 25% (aged 7), 3,3% (aged 12) and 3,6% (aged 14) in the primary teeth, 87,5% (aged 7), 3,3% (aged 12) and 0 (aged 14) in the permanent teeth. There is no treatment need in 27,5, 22,8 and 17,9% of studied groups. Extraction need was 0, 4,3 and 3,6% in 7-, 12- and 14-year-old. Restorations need was the following: one surface: 45, 65,2 and 71,4%, two surfaces 57,5%, 37, 52,4%, three surfaces: 35, 8,7, 16,7%, more than three surfaces or crown: 2,5, 1,1 and 2,4% at the age of 7, 12, 14 years. The number of DMF and dmf teeth was lower at the 12-year-old children than the previous Hungarian data.

Abstract
The achievements of the healthcare industry in the 21st century will depend on the quality of its leadership. In recognition of the contributions of the new generation of healthcare executives, MODERN HEALTHCARE salutes its 1993 Up & Comers. They are a group of healthcare professionals, all 40 or younger, who have refused to be restricted by the ways of the past. Instead, they have contributed to efforts to improve the quality of medical care, expand access to the system and reconfigure the delivery system. The group, whose accomplishments are outlined in the following pages, were selected from a field of nearly 50 candidates nominated by MODERN HEALTHCARE's editorial staff and magazine readers.

Abstract
Acid products formed by bacterial fermentation of dietary carbohydrates in the dental plaque, are required for the initiation of dental caries. The aim of the present study was to analyze nutritional and oral hygienic habits of 216 schoolchildren (108 boys and 108 girls) aged of 7, 12 and 14 years. In the studied population children brushed their teeth after meals in 42.5, 54.3 and 38.1% (in the 7, 12 and 14 year age groups respectively). The additional hygienic aids (interdental cleaning: 32.5, 42.4 and 34.5%, oral rinse: 7.5, 27.2 and 23.8%) were used only by a smaller part of the studied groups. Consumption of dairy products and fruits was satisfactory. The habit of drinking carbonic acid containing soft drinks was rather high (%). Some (2.5, 10.9 and 7.1%) of the children drink it several times a day. Fluoride containing Dentocar tablets were used only in 42.5, 3.3 and 1.2% in the studied groups.
