Congenital epulis of the jaw: a series of five cases and review of literature

This article describes five cases of congenital epulis, a rare and benign swelling in the mouth of a newborn, which is not widely known. We present five cases: four cases presented as single pedunculated nodules of the gingiva and in one case two nodules were present. Of all, 50% were located at the maxilla. Excision was performed in four of the five cases and in one case, spontaneous regression was awaited. No recurrence was reported. The characteristic features of congenital epulis are a pedunculated, flesh-pink coloured tumour with a predominant occurrence on the anterior maxillary alveolar ridge in a female newborn. Although the aetiology is unknown, most authors suggest a mesenchymal, rather than an odontogenic, origin. Endogenous hormonal factors might influence growth prenatally. Histological findings include granular cells with eosinophilic cytoplasm and small, eccentric nuclei. Despite the fact that the lesion can be a striking sight, spontaneous regression is possible and can be awaited. Indications for non-radical excision under local anaesthesia are severe upper airway obstruction and interference with feeding technique. In conclusion, we provide clinical and histological information about congenital epulis, so that this entity will be more easily recognised and relevant information given to parent

Single CD28 stimulation induces stable and polyclonal expansion of human regulatory T cells

Contains fulltext : 170288.pdf (publisher's version ) (Open Access)CD4+FOXP3+ Treg are essential for immune tolerance. Phase-1 clinical trials of Treg-therapy to treat graft-versus-host-disease reported safety and potential therapeutic efficacy. Treg-based trials have started in organ-transplant patients. However, efficient ex vivo expansion of a stable Treg population remains a challenge and exploring novel ways for Treg expansion is a pre-requisite for successful immunotherapy. Based on the recent finding that CD28-signaling is crucial for survival and proliferation of mouse Treg, we studied single-CD28 stimulation of human Treg, without T cell receptor stimulation. Single-CD28 stimulation of human Treg in the presence of recombinant human IL-2(rhIL-2), as compared to CD3/CD28/rhIL-2 stimulation, led to higher expression levels of FOXP3. Although the single-CD28 expanded Treg population was equally suppressive to CD3/CD28 expanded Treg, pro-inflammatory cytokine (IL-17A/IFNgamma) production was strongly inhibited, indicating that single-CD28 stimulation promotes Treg stability. As single-CD28 stimulation led to limited expansion rates, we examined a CD28-superagonist antibody and demonstrate a significant increased Treg expansion that was more efficient than standard anti-CD3/CD28-bead stimulation. CD28-superagonist stimulation drove both naive and memory Treg proliferation. CD28-superagonist induction of stable Treg appeared both PI3K and mTOR dependent. Regarding efficient and stable expansion of Treg for adoptive Treg-based immunotherapy, application of CD28-superagonist stimulation is of interest

Birth attendance and magnitude of obstetric complications in Western Kenya: a retrospective case–control study

BACKGROUND: Skilled birth attendance is critical in the provision of child birth related services. Yet, literature is scanty on the outcomes of child birth related complications in situations where majority of women deliver under the care of non-skilled birth attendants compared to those who are assisted by skilled providers. The study sought to assess the nature of childbirth related complications among the skilled and the non-skilled birth attendants in Western Kenya. METHODS: A case–control study was conducted among women aged 15–49 years at the household. Controls were individually matched to cases on the basis of age and socio-economic status. A total of 294 cases and 291 controls were interviewed. Data were collected on various demographic and socio-economic characteristics and women’s perception on the quality of care. All independent variables were analysed initially in bivariate models and those that were significantly associated with obstetric complications were included in multiple logistic regression model in order to control for confounding factors. Odds ratios (ORs), with 95% confidence intervals, were computed to show the association between the occurrence, magnitude and the extent to which child birth related complications were managed. RESULTS: Demographic and socio-economic characteristics of the cases and controls were similar. About 52% of the deliveries were assisted by skilled birth attendants while non-skilled providers attended to 48% of them. The odds of the occurrence of obstetric complications were greater among the women who were attended to by skilled providers in health facilities: adjusted odds ratio (AOR): 1.32 (CI 0.95, 1.84) than among those who were assisted by unskilled birth attendants, AOR 0.76 (CI 0.55, 1.06). Undignified care, high delivery and transport costs and fear of hospital procedures such as HIV tests and mishandling of the placenta were cited as some of the barriers to facility deliveries. CONCLUSION: Skilled birth attendants in facilities were associated with higher odds of the occurrence of obstetric complications compared to deliveries that were assisted by non-skilled attendants at home. Women cited many barriers which need to be addressed in order to improve their access to skilled providers for delivery and in managing obstetric complications

Neuropsychological function is related to irritable bowel syndrome in women with premenstrual syndrome and dysmenorrhea

Background There is increasing evidence demonstrating the co-occurrence of primary dysmenorrhea (PD), premenstrual syndrome (PMS), and irritable bowel syndrome (IBS) in women. This study aimed to investigate whether women who have symptoms of IBS in addition to PD and PMS also report more severe or frequent menstruation-associated symptoms and psychological complications compared to women with PD and PMS alone. Methods The study group included 182 female University students aged 18–25 years. IBS was diagnosed using the Rome III criteria. The severity of PMS and PD was determined using a 10-point visual analog scale and PSST (Premenstrual Syndrome Screening Tool), respectively. Neuropsychological functions including cognitive function, depression score, anxiety score, stress, insomnia, daytime sleepiness, quality of life and personality were assessed using standard questionnaires. Results Of the 182 young females, 31 (17.0%) had IBS. Average days of bleeding during the menstrual cycle and mean pain severity on the PSST scale were significantly greater in the group with IBS compared to the non-IBS group (p < 0.01). The non-IBS individuals scored more favorably than the women with IBS with respect to severity of depression, insomnia, daytime sleepiness (p < 0.05). The PSST scores were significantly correlated with scores for depression (r = 0.29; p < 0.001), anxiety (r = 0.28; p < 0.001), stress (r = 0.32; p < 0.001), insomnia (r = 0.34; p < 0.001) and daytime sleepiness (r = 0.31; p < 0.001); while, they were negatively correlated with cognitive abilities (r = − 0.20; p = 0.006) and quality of life (r = − 0.42; p < 0.001). Linear regression analysis showed that the PSST scores were possibly significant factors in determining the scores for depression, anxiety, stress, quality of life, insomnia and daytime sleepiness (p < 0.05). Conclusion IBS is related to psychological comorbidities, in particular depression, sleep problems and menstrual-associated disorders. IBS may exacerbate the features of PMS which should be taken into account in the management of PMS
