Background: The removal of dental plaque plays an essential role in the maintenance of oral health. Numerous powered and manual toothbrushes were manufactured to achieve this goal, but even up to this day different opinions and research results have been revealed to assess the priority of the mentioned devices., Aim: Comparison of powered and manual toothbrushes on the basis of periodontal parameters and safety., Materials and Methods: Electronic search of the databases of MEDLINE and EMBASE (until May 2014) was carried out with the help of keywords in order to find relevant trials. The inclusion criteria were as follows: randomised controlled clinical trials, adult population, the presence of at least 15 permanent teeth. Split-mouth trials and interventions carried out by dental professionals, were excluded. Primary outcomes were the changes of plaque and gingival indices, while secondary outcomes were probing pocket depth (PPD), safety and quality assessment. The effect-size of the interventions was expressed by the standardised mean difference (SMD) with 95% confidence interval (CI). Random-effects models were performed., Results: Electronic search resulted in 173 hits. 21 trials with the total number of 1500 subjects were then eligible for the meta-analysis. Both toothbrushes were safe, without considerable side effects on soft or hard tissues. Powered toothbrushes seemed to be generally more effective in removing plaque (-9%), reducing gingivitis (-6%) and preventing calculus formation. The SMDs for plaque and gingival indices were -0,40 (95% Cl: -0,95 to -0,16) and -0,29 (95% Cl: -0,56 to -0,03) respectively, in favour of the powered devices. There was no significant difference in changes of PPD. By further dividing the powered toothbrushes according to their mode of action, the plaque removal effect of the rotation oscillation (plus three dimensional), side to side sonic and ultrasonic toothbrushes seemed to be significantly better, than their manual ones, while the counter oscillation and the ionic toothbrushes did not perform better. Quality assessment and sensitivity analysis revealed various types of bias up to a certain extent. Consequently, no trial was found to be eligible for the highest quality criteria., Conclusions: The investigated rotation oscillation and vibrating toothbrushes appeared to be statistically more effective than their manual counterparts, although there is little known about its clinical relevance. The advantage of the electric toothbrushes disappears in case of adequately instructed and motivated patients that highlights the importance of individualised oral hygiene education. The design of the trials shows high heterogeneity, therefore their clinical implications should be handled carefully.

The restoration of cervical abrasions, erosions or cervical carious lesions is still challenging because of their unpredictable adhesion and possible negative effects on the marginal plaque accumulation. The impact of three different glass ionomer cements (GIC) on the marginal gingiva and root sensitivity was studied. Furthermore, it was investigated in details, whether or not a recently developed light curing varnish (GC Coat - EQUIA) had any additional effect on the gingival tissue. A total number of 30 non-smokers with healthy gingiva having at least one cervical supra/paragingival abrasion/erosion/abfraction defects were enrolled in the present study. The cervical defects were randomly restored by using one of the three GIC and the gingival parameters were recorded and evaluated at baseline, 6 weeks and 6 months. According to our results root sensitivity were substantially decreased in all the three groups. Plaque scores were also reduced in all groups with the greatest improvement at the sites where the new varnish were applied. Although this improvement was not reflected by the gingival parameters, such as bleeding on probing and crevicular fluid flow, since both were slightly increased in the varnish group. However, neither the intra-group, nor the intergroup differences reached statistical significance. Consequently, the three investigated GIC did not significantly affect the gingival health, therefore they might serve as alternative for the treatment of such cervical lesions. Nevertheless, the new light cure varnish-coated GIC did not seem to be either clinically or statistical significantly more favorable.

Electrosurgery and radiosurgery bear certain popularity in contemporary dentistry. Nevertheless, the inadequate treatment allocation may lead to tissue necrosis. A young female patient was referred to our department following root canal treatment (RCT) by radiosurgical device. Necrotised alveolar bone, lack of keratinized gingiva and increased tooth mobility were noticed. After considering all the treatment options, we attempted to keep the tooth. Therefore, the necrotised part of the alveolar process was removed and the gingival fringe was rejuvenated alongside root surface debridement. The tooth was then splinted with glass fibre reinforced composite and appropriate RCT was completed. After ten months of improvement periodontal reconstructive surgery with deproteinized bovine bone mineral and connective tissue graft was carried out. Substantial improvement was observed at the six month reassessment, including complete healing of the gingiva. The composite splint was then removed due to discontinued mobility. The tooth and the adjacent periodontium remained stable for seven years. Nevertheless, external root resorption was recently developed that was treated with glass ionomer cement filling and regenerative periodontal surgery using enamel matrix derivative (EMD). Ultimately, the tooth is still in place providing satisfactory function and aesthetics.

Unlabelled: Health status of ambulance personnel has an important impact on the quality of patient care. Surveys in some smaller regions of Hungary have been conducted on health behavior of ambulance personnel; however they do not mirror the complexity of multidimensional health status in this respect. The aim of the present study is to examine the self-perceived health status of ambulance personnel (AP) and its most salient work related and individual factors., Methods: A quantitative cross-sectional survey was carried out among AP of the Hungarian National Ambulance and Emergency Service in 2008. The survey covered all the regions and sample taking ensured the study to be of representative value. Anonymously 364 individuals gave their answers that could be evaluated. After data procession and coding, records were statistically analyzed by SPSS 15.0. Spearman correlation, chi-square test and multivariable logistic regression analyses were applied to measure the significance of variables. The survey was conducted with a self-fill-in questionnaire measuring the following dimensions of self-perceived health: self-rated health, self-rated physical fitness and limitation in daily activities by health problems., Results: The results revealed that self-perceived general health status of ambulance personnel does not differ significantly among the emergency units in many terms. However, there are significant differences regarding the complexity of the duties what they have to deal. In their self rated health 1.9 times (95% CI:1.2-2.8), in their self rated physical fitness 2.0 times (95% CI:1.3-3) and in the limitation of daily activities by health problems 1.9 times (95% CI:1.2-3.1) those ambulance personnel feel more favorable who do any kind of sports activity. Generally they experience serious stress; they have not enough leisure time and hardly do sport. Due to their bad lifestyle all fifth ambulance personnel suffer from serious obesity., Conclusion: Physical activity may enhance self perceived health even though if the person delivers physical symptoms. Regular training to increase the physical fitness should be implemented for ambulance personnel that could well contribute to copying with psychological trauma.

At the 25th anniversary of the identification of HIV virus as the causative agent of AIDS, virologist and clinician authors provide an overview of the discovery and identification of HIV, its significance in the development of clinical diagnosis of HIV/AIDS, which led to the development of effective antiretroviral treatment. Besides the epidemiological and sociological aspects of the infection, authors provide a detailed chronology of the special aspects of the fight against HIV/AIDS in Hungary, from the diagnosis of the first HIV and AIDS cases, through the establishment of the nationwide screening network and counseling units to the appearance of drug resistant virus mutants, and the recent penetration of African HIV strains to the country. Further actions are urged locally and worldwide for the better understanding the interactions of the human host organism and the HIV virus for the more effective treatment. For these political consensuses, a large scale long term financial support, views based on scientific and public health evidences, and cooperation of the whole society worldwide are needed.

The authors' report a case of a 26-year-old female. In 1996, and 1997 she underwent cosmetic lip augmentations (polymethyl methacrylate and silicone). After a six-year symptom free period sudden swelling of the lips developed and red-brown papules and subcutaneous nodules appeared in the scars of various body parts ( permanent make-up, tattoos, umbilical piercing). The clinical features, radiological signs and histology proved the diagnosis of systemic sarcoidosis. Systemic corticosteroid treatment was introduced. After 4 months of treatment the pulmonary and clinical symptoms showed regression. To be able to suspend the systemic treatment the silicone implant was removed.

Unlabelled: Hepatitis C virus RNA in the skin eruption from patients with prurigo and chronic hepatitis C. Since the discovery of hepatitis C virus (HCV) in 1989, many cutaneous disorders have been observed in patients suffering from chronic HCV infection. The relationship between HCV infection and cryoglobulinemia and porphyria cutanea tarda is clearly established, however, the link between HCV and other skin diseases is still controversial., Aim: Two patients with intense pruritus and secondary prurigo in chronic C hepatitis have been presented., Methods: The chronic hepatitis C of the patients were proved by elevated ALT and AST level, anti HCV (ELISA), HCV-PCR serological examination and liver biopsy. The skin lesions were accompanied by severe itching. According to clinical symptoms the patients suffered from prurigo simplex., Results: HCV RNA in the skin specimen from the biopsy of the skin lesion was detected by RT PCR method, but the non affected skin specimen from the patients was HCV RNA negative., Conclusions: This report is a case of prurigo simplex with chronic C hepatitis proving a direct relation between the HCV infection and prurigo.

The authors discuss the case of a patient suffering from an auditory-pigmentary syndrome. The patient in whom the Waardenburg syndrome had never been diagnosed before was observed because of another disease, which quite frequently causes hearing loss in childhood. In a short review of the literature, the authors describe the other components of the syndrome and the recent information about the genetic background of the disease.

Introduction and Aim: Human herpesvirus 7 in pityriasis rosea, this and other viruses in papular-purpuric gloves-and-socks syndrome have been implicated, but their primary or recurrent infections are still in question., Patient and Methods: In one available blood sample, therefore, IgM, IgG and its high avidity fraction characteristic for recurrent infections were quantitated by indirect immunofluorescence. Peripheral lymphocytes were subjected to nested polymerase chain reaction to detect viral DNA, or cocultivated with several cell cultures., Results: One third of 33 pityriasis rosea patients had elevated IgM, another third had elevated IgG without high avidity molecules to human herpesvirus 7 suggesting primary infection. Thirty percent of controls, more than half of the patients had virtual DNA in their lymphocytes, but only one in 5 skin biopsy specimens were PCR positive. All three co-cultivation attempts yielded viruses extremely rapidly, verified by electron microscopy, polymerase chain reaction and monoclonal antibodies as human herpesvirus 7. These are the first isolates in the geographical regions of Hungary. These data suggest that pityriasis rosea is the consequence of a primary human herpesvirus 7 infection in seronegative adults, and only occasionally is due to virus reactivation. One patient with gloves-and-socks syndrome had an acute, another patient had a persistent coinfection with human herpesvirus 7 and parvovirus B19, two others had a primary herpesvirus 7 infection. Interestingly, this disease might be elicited by both viruses individually or in synergism., Conclusion: Neither human herpesvirus 7 nor parvovirus B19 infect skin cells, but both can be detected in the infiltrating lymphocytes of skin eruptions, in which they induce an altered mediator production, that might be responsible for the general and local symptoms.
