INTRODUCTION Traumatic bone cyst is a pseudocyst presented as an asymptomatic unilocular single lesion with an empty cavity without epithelial lining. Its etiology is still debated, it is more frequent among young people and it is often localized in posterior mandible zone. A case report is described about diagnosis and treatment of a traumatic bone cyst in anterior zone of lower mandible with a conservative approach. CASE PRESENTATION The report describes a 22 years old female with a traumatic bone cyst in anterior mandible as accidental discovery from a routine orthopantomography. A conservative approach is conducted to treat the lesion through a sub-marginal incision, an osteotomy with ultrasound, a filling of the cavity with advanced platelet-rich fibrin (A-PRF+) membranes and repositioning of the cortical bone. The radiological follow-up to 6 months confirms the healing of the lesion. CONCLUSION The conservative approach ensures optimal bone healing and avoid gingival recessions at six months follow-up, showing to be a good alternative for satisfactory defect resolution in similar clinical scenarios.

DESIGN Prospective, randomised clinical trial. SETTING Tertiary referral centre. PARTICIPANTS Sixty-three adult patients with ethmoidal involvement in cone beam computerised tomography (CBCT) whose first-line medical treatment with topical corticosteroids had failed and who were candidates for ESS were randomised either to a DES group, which received triamcinolone acetonide stents (n = 34), or to a topical intranasal corticosteroid group (n = 29) that used optimally dosed triamcinolone acetonide nasal spray. OUTCOME MEASURES Patients were followed up prospectively for 6 months and at 36 months. Freedom from ESS was the primary endpoint. Further, we identified those factors predicting ESS. RESULTS At 6 months, ESS could be prevented in almost half of the patients in both groups (DES 13/28, 46.4%, nasal spray 14/29, 48.3%). At 36 months, 20/28 (71.4%) patients in the DES group and 18/29 (62.1%) in the nasal spray group had been operated. The differences were not statistically significant at either timepoint. Patients who smoked (14/19, 73.7% vs 16/38, 42.1%) were more likely to be operated at 6 months. CONCLUSION Endoscopic sinus surgery can be prevented using both therapies in the medium term in almost half of cases with neither therapy being statistically superior. This effect was somewhat diminished in the long term with a trend towards more patients being operated in the DES group. Considering the additional costs, the need for general anaesthesia and the potential side effects associated with DES, its potential clinical role appears to be limited. Smoking was significantly associated with ESS. © 2020 John Wiley & Sons Ltd.AIMS This experimental study focuses on survival and consistence of Vibrio parahaemolyticus in cold-water sediments and how increasing temperature and nutritional availability can affect growth. METHODS AND RESULTS A pathogenic strain of V. parahaemolyticus was inoculated in seawater microcosms containing bottom sediment. Gradually, during 14 days, the temperature was upregulated from 8 to 21°C. Culturable V. parahaemolyticus was only found in the sediment but declined over time and did not recover even after another 2 days at 37°C. Numbers of culturable bacteria matched the amount found by q-PCR indicating that they did not enter a dormant state, contrary to those in the water layer. After adding decaying phytoplankton as fertilizer to the microcosms of 8 and 21°C for 7 and 14 days, the culturability of the bacteria increased significantly in the sediments at both temperatures and durations of exposure. CONCLUSION The study showed that V. parahaemolyticus can stay viable in cold-water sediment and growth was stimulated by fertilizers rather than by temperature. SIGNIFICANCE AND IMPACT OF THE STUDY Vibrio parahaemolyticus is a common cause of seafood-borne gastroenteritis and is today recognized in connection to increasing ocean temperature. The results indicate that this pathogen should be considered a risk in well-fertilized environments, such as aquacultures, even during cold periods.

The key step in these syntheses involve a Rh-catalyzed C-C/C-H activation cascade of 3-arylcyclopentanones, which provides a rapid and enantioselective route to access the polysubstituted tetrahydronaphthalene cores presented in these natural products. Other important features include 1) the direct C-H amination of the tetralone substrate in the synthesis of (-)-microthecaline A, 2) the use of phosphoric acid to enhance efficiency and regioselectivity for problematic cyclopentanone substrates in the C-C activation reactions, and 3) the direct conversion of serrulatane into amphilectane diterpenes by an allylic cyclodehydrogenation coupling. © 2020 Wiley-VCH Verlag GmbH & Co.

Additionally, poor diet is also considered a predicting, perpetuating, or underlying factor in chronic musculoskeletal pain. This narrative review provides an overview of current knowledge on the relationship between nutrition and chronic musculoskeletal pain (ie, inflammation, obesity, homeostatic balance, and central sensitization as underlying mechanisms). This review also identifies how dietary intake assessments and nutritional behaviour interventions for chronic musculoskeletal pain can be used in clinical practice and identifies areas in need of additional research. Based on the available literature, dietary behavior and quality could have an impact on chronic musculoskeletal pain conditions, but the direction of this impact is unclear. There is a need for additional human nutrition studies that focus on specific musculoskeletal pain conditions and underlying pathologies.
