TL;DR: Recurrent parotid swelling is a common feature of primary Sjögren syndrome in childhood and often occurs as a presenting feature and Sicca symptoms may be rarer.
Abstract: Primary Sjogren syndrome (SS) is very rare in childhood. We collected a series of primary paediatric SS cases from different centres. A data collection form was prepared and sent to rheumatologists who were willing to participate. Data on 40 cases of primary SS with onset before the 16th birthday were collected. Almost all patients (35/40) were females, age at onset varied from 9.3 to 12.4 years (mean 10.7 years). Signs and symptoms at disease onset were mainly recurrent parotid swelling followed by sicca symptoms. Abnormal laboratory tests were found in the majority of cases. Regarding treatment, 22 patients were treated at some time with oral corticosteroids, seven with non-steroidal anti-inflammatory drugs, and five with hydroxychloroquine; two patients needed cyclosporine and one cyclophosphamide. Follow-up varied from 0 to 7.5 years from onset, without major complications in the majority of patients. Conclusion: recurrent parotid swelling is a common feature of primary Sjogren syndrome in childhood and often occurs as a presenting feature. Sicca symptoms may be rarer.

TL;DR: The Gly16 allele of the beta2-adrenergic receptor gene predisposes to nocturnal asthma and this may also explain the association with asthma severity, and neither polymorphism modulates the risk for bronchial hyperresponsiveness or mild asthma.
Abstract: Background Two common polymorphisms of the β2-adrenergic receptor gene ( Arg16Gly and Gln27Glu ) have been extensively studied for their possible association with asthma-related phenotypes, but the results of individual studies have been inconclusive. Objective We aimed to integrate quantitatively the available evidence on the association of the Arg16Gly and the Gln27Glu polymorphisms with asthma, nocturnal asthma, asthma severity, and bronchial hyperresponsiveness. Methods Meta-analysis of case-control and cohort studies using random effects models. Results A total of 28 studies were included in the meta-analysis. The summary estimates suggested that neither the Gly16 nor the Glu27 allele contributes to asthma susceptibility overall (odds ratio [OR], 1.01; 95% CI, 0.90-1.13; and OR, 0.95; 95% CI, 0.83-1.09, respectively) or to bronchial hyperresponsiveness (OR, 0.90; 95% CI, 0.77-1.05; and OR, 1.07; 95% CI, 0.94-1.22, respectively). There was a strong association of Gly16 with nocturnal asthma (OR, 2.20; 95% CI, 1.56-3.11) and a less strong association with severe or moderate rather than milder asthma (OR, 1.42; 95% CI, 1.04-1.94). No such effects were seen for the Glu27 allele (OR, 1.02; 95% CI, 0.74-1.40; and OR, 0.82; 95% CI, 0.59-1.14, respectively). Moreover, there was evidence that Gly16 homozygotes had a much higher risk for nocturnal asthma (OR, 5.15; 95% CI, 2.44-10.84) and asthma severity (OR, 2.84; 95% CI, 1.62-4.96) than the Arg16 homozygotes. Conclusion The Gly16 allele of the β2-adrenergic receptor gene predisposes to nocturnal asthma, and this may also explain the association with asthma severity. Neither polymorphism modulates the risk for bronchial hyperresponsiveness or mild asthma.

TL;DR: Wolbachia infections were detected in both laboratory and natural populations of several different Glossina species and the detection of horizontal gene transfer events, in which Wobachia genes were inserted into the tsetse flies fly nuclear genome.
Abstract: Background
Wolbachia is a genus of endosymbiotic α-Proteobacteria infecting a wide range of arthropods and filarial nematodes. Wolbachia is able to induce reproductive abnormalities such as cytoplasmic incompatibility (CI), thelytokous parthenogenesis, feminization and male killing, thus affecting biology, ecology and evolution of its hosts. The bacterial group has prompted research regarding its potential for the control of agricultural and medical disease vectors, including Glossina spp., which transmits African trypanosomes, the causative agents of sleeping sickness in humans and nagana in animals.
