Patients with NBS develop both T and B cell lymphomas. Treatment outcome is poor and might be improved by administering over 80% of drug doses. Although toxicity often depends upon drug doses, our patients experienced equal grade 3 and 4 toxicities whether they received more or less than 80% of the chemotherapeutic agents.

Background Comparative optimism, the belief that negative events are more likely to happen to others rather than to oneself, is well established in health risk research. It is unknown, however, whether comparative optimism also permeates people’s health expectations and potentially behaviour during the COVID‐19 pandemic. Objectives Data were collected through an international survey (N = 6485) exploring people’s thoughts and psychosocial behaviours relating to COVID‐19. This paper reports UK data on comparative optimism. In particular, we examine the belief that negative events surrounding risk and recovery from COVID‐19 are perceived as more likely to happen to others rather than to oneself. Methods Using online snowball sampling through social media, anonymous UK survey data were collected from N = 645 adults during weeks 5‐8 of the UK COVID‐19 lockdown. The sample was normally distributed in terms of age and reflected the UK ethnic and disability profile. Findings Respondents demonstrated comparative optimism where they believed that as compared to others of the same age and gender, they were unlikely to experience a range of controllable (eg accidentally infect/ be infected) and uncontrollable (eg need hospitalization/ intensive care treatment if infected) COVID‐19‐related risks in the short term ( P < .001). They were comparatively pessimistic (ie thinking they were more at risk than others for developing COVID‐19‐related infection or symptoms) when thinking about the next year. Discussion This is the first ever study to report compelling comparative biases in UK adults’ thinking about COVID‐19 We discuss ways in which such thinking may influence adherence with lockdown regimes as these are being relaxed in the UK.

Background: Early childhood caries (ECC) remains highly prevalent in preschool children worldwide. Dental caries affects every second 3-year-olds in Poland. The aim of the study was to assess protective factors for ECC in 3-year-olds.Methods: A cross-sectional survey was conducted in 2017 among 3-year-olds attending kindergartens in all 16 provinces of Poland. The questionnaire included socioeconomic factors, and oral health behaviors. Decayed, missing due to caries and filled teeth and surfaces were assessed. Caries indices (dmft and dmfs), percentage of caries-free and severe ECC (S-ECC) were calculated. The Student's t-test, Spearman correlation, univariate and multivariate logistic regression (the odds ratios (OR) and adjusted odds ratios (AOR): confounding factors: socioeconomic conditions, oral health behaviors) were performed; p &lt; 0.05.Results: A total of 1,638 children were included. ECC was confirmed in 41.1%; S-ECC in 23.4%. The dmft index was 1.85 ± 3.14, dmfs = 2.99 ± 6.56. Spearman correlation [socioeconomic factors, especially mother's education (r = −0.148, p &lt; 0.001) and family's economic status (r = −0.071, p = 0.004)], despite were statistically significant, indicate very weak relationships with dmft index. After 12th month of life not giving any beverages before bedtime and at night, but water or unsweetened milk only, healthy snacking (sandwiches, fresh fruit), or water on a daily basis decreases the probability of caries development (for S-ECC: OR = 0.37, AOR = 0.47, AOR2 = 0.37; p &lt; 0.01), even if inappropriate dietary behaviors or hygiene practices were simultaneously present. Brushing of a child's teeth twice a day lowered the odds of caries (for S-ECC: OR = 0.78, p = 0.031; AOR = 0.81, p = 0.081; AOR2 = 0.84, p = 0.131), but this effect was less intense when inappropriate dietary behaviors were accounted for. Children of parents with good self-assessment of their teeth were more often caries-free (61.4 vs. 42.9%; p = 0.006) and had lower dmft indices (1.67 vs. 2.93; p = 0.002).Conclusions: Preventing a child after 12th month of life from getting any beverages before bedtime, water or unsweetened milk only, sandwiches and fresh fruit as snacks, or water given to on a daily basis, tooth brushing twice a day decrease the odds of caries in 3-year-olds. Diet appears to have primary significance in the etiology of ECC, since tooth brushing can only partly attenuate the impact of inappropriate dietary behaviors on dental caries. Children are more often caries-free and have lower severity of caries if their parents' dentition is self-assessed as healthy.

J Oral Pathol Med (2012) 41: 568–576 Background:  Oral microbial flora and a damaged oral mucosa may increase the risk of bacteriemia, fungemia and complications in immunocompromised patients. Aim of the Study:  Assessment of presence: bacteria and Candida spp. in different oral lesions, and the incidence of bacteremia in the case of a damaged mucosa in transplant recipients and patients receiving anti‐tumour chemotherapy. Material and Method:  Forty‐five patients – 18 months to 18 years of life, were included (20 – organ recipients, 14– anti‐tumour chemotherapy, 11 – control group). Clinical, oral mucosa examination focused on the type, severity and site of lesions, and microbiology assessed the presence of bacteria and fungi in the material from lesions. Blood cultures were performed in ten immunocompromised patients with manifestations of systemic infection. The control material consisted of blood cultures made prior to the onset of oral lesions and after 4–6 weeks following their remission in a diagnosed bacteremia. The statistical analysis was performed. Results:  In the subjects with secondary immunodeficiency, among other coagulase‐negative Staphylococcus (CoNS), Candidia spp. were more frequent. In cancer patients, mucositis was associated with Candida spp., Streptococcus spp. Organ recipients with stomatitis exhibited the presence of CoNS, Streptococcus viridians and other. Oral lesions in the control group contained Haemophilus parainfluenzae, Neisseria spp. and Staphylococcus aureus. In 30% of immunocompromised patients, oral lesions were accompanied by bacteremia. Conclusions:  A correlation has been found between oral lesions and the presence of S. aureus in patients without secondary immunodeficiency, and of CoNS, Enterococcus spp., Candida spp. in immunocompromised patients.

Introduction. Premature loss of the first primary molar may cause malocclusion or impair permanent tooth eruption. Aim. The aim of the study was to assess spatial changes in the dental arch after unilateral premature extraction of the first primary molar. Material and methods. The alginate impressions were taken in patients aged between 5 and 7 years who met the inclusion criteria based on medical history, clinical examination and panoramic x-ray during a preliminary qualifying examination 14 days before or on the day of extraction (before the procedure), as well as during follow up (at months 1, 3, 6 and 12 after extraction). Gypsum models were used to measure the circumference of the arch, the posterior and intercanine width, as well as the interdental distance: IIID-VM, IIID-VD on the side of extraction and the opposite side of the arch. The data were analysed statistically (Statistica 10, Statsoft, p < 0.05). Results. A total of 14 mandibular and 16 maxillary teeth were extracted in 27 children aged between 5 and 7 years (mean age ± SD = 6.64 ± 1.01; 15 boys and 12 girls). A significant loss of interdental spaces for IIID-VM and IIID-VD between the study vs. control side due to distalisation of canine and mesialisation of the second primary molar was observed. Much less significant displacement of these teeth was noted in the case of the presence of the first permanent molar at the time of first primary molar extraction. Conclusions. Premature loss of first primary molars results in reduced interdental distances which does not hinder the eruption of their permanent successors. There is no need for space maintainers.
