BACKGROUND: Although enamel matrix derivative (EMD) has been used to promote periodontal regeneration, little is known of its effect on the microbiome. Therefore, this investigation aimed to identify the changes in periodontal microbiome following treatment with EMD using a deep-sequencing approach. METHODS: Thirty-nine patients having mandibular class II buccal furcation defects were randomized to beta-tricalcium-phosphate/hydroxyapatite graft (BONE group), EMD+BONE or EMD alone...

A longstanding question is whether neuroinflammation is present in children symptomatic for Tourette syndrome (TS) with positive streptococcal serology and throat cultures. The objective was to directly test for it using modern hypothesis-driven approaches. Profiling studies for 14 immune cell types (flow cytometry), 7 chemokines/cytokines (ELISA), oligoclonal bands, and other immunoglobulins were performed in this IRB-approved study of 5 children with TS and streptococcal markers compared to data from 26 non-inflammatory pediatric neurological controls...

Pharyngitis in most cases is due to viral microorganisms however drug therapy without the detection of etiological agent leads to unnecessary use of antibiotics. On the other hand, when the etiologic agent is group A beta-hemolytic streptococci (GAS) it is important to identify the etiologic agent rapidly which will guide the treatment with appropriate antibiotics. The use of highly sensitive rapid tests will contribute significantly to early diagnosis and appropriate therapy. The aim of this study is to evaluate the efficacy of Mascia Brunelli rapid antigen test for the detection of GAS in throat swab samples...

Recent advances in the scale and diversity of population genomic datasets for bacteria now provide the potential for genome-wide patterns of co-evolution to be studied at the resolution of individual bases. Here we describe a new statistical method, genomeDCA, which uses recent advances in computational structural biology to identify the polymorphic loci under the strongest co-evolutionary pressures. We apply genomeDCA to two large population data sets representing the major human pathogens Streptococcus pneumoniae (pneumococcus) and Streptococcus pyogenes (group A Streptococcus)...

BACKGROUND: The nasopharynx is a reservoir for pathogens associated with respiratory illnesses such as asthma. Next-generation sequencing (NGS) has been used to characterize the nasopharyngeal microbiome of infants and adults during health and disease; less is known, however, about the composition and temporal dynamics (i.e., longitudinal variation) of microbiotas from children and adolescents. Here we use NGS technology to characterize the nasopharyngeal microbiomes of asthmatic children and adolescents (6 to 18 years) and determine their stability over time...

OBJECTIVE: According to recent observations, the insufficiently targeted use of antibiotics is creating increasingly resistant bacterial strains. In this context, it seems increasingly clear the need to resort to extreme and prudent rationalization of antibiotic therapy, especially by the physicians working in primary care units. In clinical practice, actually the general practitioner often treats multiple diseases without having the proper equipment. In particular, the use of a dedicated, easy to use diagnostic test would be one more weapon for the correct diagnosis and treatment of acute pharyngo-tonsillitis...

Thyroid storm has a high mortality rate and is often associated with a precipitating factor such as intercurrent illness or infection. It is rare in pediatric patients. Cardiac disease in hyperthyroidism mostly manifests itself as tachycardia but more serious cardiac findings have also been described. A 5-year-old male with recent strep throat infection presented with dilated cardiomyopathy, hematuria, and symptoms and lab findings consistent with severe hyperthyroidism. He was diagnosed with thyroid storm secondary to concurrent Graves' disease and poststreptococcal glomerulonephritis (PSGN)...

Leukocytospermia is a physiologic condition defined as human semen with a leukocyte count of >1 x 10(6) cells/ml that is often correlated with male infertility. Moreover, bacteriospermia has been associated with leukocytospermia ultimately leading to male infertility. We have found that semen samples with >1 x 10(6)/ml leukocytes and/or bacteriospermia have oxidative predominance as evidenced by augmented protein carbonyl and lipid peroxidation status of the semen which is implicated in sperm dysfunction...

The composition of the gut microbiome reflects the overall health status of the host. In this study, stool samples representing the gut microbiomes from 6 gluten-sensitive (GS) captive juvenile rhesus macaques were compared with those from 6 healthy, age- and diet-matched peers. A total of 48 samples representing both groups were studied using V4 16S rRNA gene DNA analysis. Samples from GS macaques were further characterized based on type of diet administered: conventional monkey chow, i.e., wheat gluten-containing diet (GD), gluten-free diet (GFD), barley gluten-derived diet (BOMI) and reduced gluten barley-derived diet (RGB)...

Sharon L Kracoff
OBJECTIVES: Nontraumatic compartment syndrome is frequently difficult to diagnose but this is especially troublesome in infants. Pain is the most sensitive sign and is characteristically severe and refractory to routine analgesia. Failure to diagnose and treat can lead to disability, multiorgan failure, and death. Surgical intervention is crucial and includes emergent fasciotomy, debridement, nerve decompression, and later skin grafting. Streptococcal myositis causing compartment syndrome is more likely in the immunocompromised patient...

BACKGROUND: Reduced salivation is considered a major clinical feature of most but not all cases of primary Sjögren's syndrome (pSS). Reduced saliva flow may lead to changes in the salivary microbiota. These changes have mainly been studied with culture that typically recovers only 65% of the bacteria present. OBJECTIVE: This study was to use high throughput sequencing, covering both cultivated and not-yet-cultivated bacteria, to assess the bacterial microbiota of whole saliva in pSS patients with normal salivation...

beta-Haemolytic streptococci of groups C (GCS) and G (GGS) from human infections typically belong to Streptococcus dysgalactiae and are important human pathogens. Among GGS (183 isolates), several emm-types were identified without significant differences between different sites of isolation. For GCS (79 isolates), the type-distribution was markedly different and more restricted.
