Antibiotic use for irreversible pulpitis

Background Irreversible pulpitis, which is characterised by acute and intense pain, is one of the most frequent reasons that patients attend for emergency dental care. Apart from removal of the tooth, the customary way of relieving the pain of irreversible pulpitis is by drilling into the tooth, removing the inflamed pulp (nerve) and cleaning the root canal. However, a significant number of dentists continue to prescribe antibiotics to stop the pain of irreversible pulpitis.This review updates the previous version published in 2016. Objectives To assess the effects of systemic antibiotics for irreversible pulpitis. Search methods We searched Cochrane Oral Health's Trials Register (to 18 February 2019); the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 1) in the Cochrane Library (searched 18 February 2019); MEDLINE Ovid (1946 to 18 February 2019); Embase Ovid (1980 to 18 February 2019); US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov (searched 18 February 2019); and the World Health Organization International Clinical Trials Registry Platform (searched 18 February 2019). There were no language restrictions in the searches of the electronic databases. Selection criteria Randomised controlled trials which compared pain relief with systemic antibiotics and analgesics, against placebo and analgesics in the acute preoperative phase of irreversible pulpitis. Data collection and analysis Three review authors screened studies and extracted data independently. We assessed the certainty of the evidence of included studies using GRADE. Pooling of data was not possible and a descriptive summary is presented. Main results No additional trials could be included in this update. One trial at low risk of bias evaluating oral penicillin in combination with analgesics versus placebo with analgesics, involving 40 participants was included in a former update of the review. The certainty of the evidence was rated low for the different outcomes. Our primary outcome was patient‐reported pain (intensity/duration) and pain relief. There was a close parallel distribution of the pain ratings in both the intervention (median 6.0, interquartile range (IQR) 10.5), and for placebo (median 6.0, IQR 9.5) over the seven‐day study period. There was insufficient evidence to claim or refute a benefit for penicillin for pain intensity. There was no significant difference in the mean total number of ibuprofen tablets over the study period: 9.20 (standard deviation (SD) 6.02) in the penicillin group versus 9.60 (SD 6.34) in the placebo group; mean difference ‐0.40 (95% confidence interval (CI) ‐4.23 to 3.43; P = 0.84). This applied equally for the mean total number of Tylenol tablets: 6.90 (SD 6.87) used in the penicillin group versus 4.45 (SD 4.82) in the placebo group; mean difference 2.45 (95% CI ‐1.23 to 6.13; P = 0.19). Our secondary outcome on reporting of adverse events was not addressed in this study

ACCORD (ACcurate COnsensus Reporting Document): A reporting guideline for consensus methods in biomedicine developed via a modified Delphi

\ua9 2024 Gattrell et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.Background In biomedical research, it is often desirable to seek consensus among individuals who have differing perspectives and experience. This is important when evidence is emerging, inconsistent, limited, or absent. Even when research evidence is abundant, clinical recommendations, policy decisions, and priority-setting may still require agreement from multiple, sometimes ideologically opposed parties. Despite their prominence and influence on key decisions, consensus methods are often poorly reported. Our aim was to develop the first reporting guideline dedicated to and applicable to all consensus methods used in biomedical research regardless of the objective of the consensus process, called ACCORD (ACcurate COnsensus Reporting Document). Methods and findings We followed methodology recommended by the EQUATOR Network for the development of reporting guidelines: a systematic review was followed by a Delphi process and meetings to finalize the ACCORD checklist. The preliminary checklist was drawn from the systematic review of existing literature on the quality of reporting of consensus methods and suggestions from the Steering Committee. A Delphi panel (n = 72) was recruited with representation from 6 continents and a broad range of experience, including clinical, research, policy, and patient perspectives. The 3 rounds of the Delphi process were completed by 58, 54, and 51 panelists. The preliminary checklist of 56 items was refined to a final checklist of 35 items relating to the article title (n = 1), introduction (n = 3), methods (n = 21), results (n = 5), discussion (n = 2), and other information (n = 3). Conclusions The ACCORD checklist is the first reporting guideline applicable to all consensus-based studies. It will support authors in writing accurate, detailed manuscripts, thereby improving the completeness and transparency of reporting and providing readers with clarity regarding the methods used to reach agreement. Furthermore, the checklist will make the rigor of the consensus methods used to guide the recommendations clear for readers. Reporting consensus studies with greater clarity and transparency may enhance trust in the recommendations made by consensus panels

Experiences of rosacea and its treatment: An interpretative phenomenological analysis

Background Whilst rosacea is a chronic skin condition, the condition can often have a large psychosocial impact on the individual. There is therefore a need to understand the experience of living with rosacea from the patient perspective. Objectives To examine the experience of living with rosacea and the experience of seeking and receiving treatment. Methods Nine participants took part in semi-structured interviews, which were analysed using interpretative phenomenological analysis. Results Three superordinate themes were identified within the data; self-consciousness, which focused on the fear of others’ assigning blame to participants for having caused symptoms; avoidance, concealment, and hiding emotions, referring to the coping strategies participants employed in response to rosacea; and inconsistencies in GP treatment and guidance, which focused on the need for medical professionals to assess the psychosocial well-being of patients with rosacea. Conclusions Rosacea can have a negative impact on the daily life of people with the condition, contributing to lowered self-esteem, embarrassment, and feelings of shame. Engaging in emotion-focused and behavioural/avoidant-focused coping strategies increased participant's confidence and reduced their avoidance of social situations. However, such strategies might still serve to maintain underlying unhelpful cognitive processes. Consequently, it is important for medical professionals to assess for the presence of cognitive factors that might contribute to maintaining distress in patients with rosacea, and where unhelpful thoughts or beliefs are reported, patients may need to be referred for psychological support

Vehicles for atopic dermatitis therapies: more than just a placebo

A topical vehicle is a ‘carrier system’ for an active pharmaceutical (or cosmetic) substance, referred to hereafter as the drug, but a vehicle may also be used on its own as an emollient to ameliorate dry skin. It is well established that the vehicle plays an important role in determining the bioavailability of a given drug at its ultimate target within the skin. Yet in the treatment of atopic eczema/dermatitis (AD), wherein the structure and function of the skin's outer barrier play a pivotal role in the development and course of the condition, the interaction of the vehicle with this barrier carries a particular importance. It is now clear that the often-considered inert excipients of a vehicle bring about changes within the skin at the molecular level that promote barrier restoration and enhance innate immune defenses with therapeutic value to AD patients. Moreover, the vehicle control in randomized controlled trials (RCTs) increasingly displays significant efficacy. In light of this, we consider the implications of vehicle design in relation to AD pathophysiology and the role vehicles play as controls in RCTs of new drug treatments for this condition

Solitary neurofibroma of the gingiva with prominent differentiation of Meissner bodies : a case report

<p>Abstract</p> <p>Background</p> <p>Oral neurofibromas are peripheral nerve sheath tumors, similar to schwannomas. Histological variations in oral neurofibromas are relatively uncommon.</p> <p>Case presentation</p> <p>Here, we present a case of unique variation in the observed characteristics of a neurofibroma, with no relation to neurofibromatosis type-1 or von Recklinghausen disease of the skin. The neurofibroma was observed in the right mandibular gingiva of a 32-year-old Japanese woman. Histologically, it differed from conventional neurofibromas in that the tumor was composed of a mixture of fine fibrillary collagen in sheets and/or cords of neoplastic Schwann cells containing numerous clusters of Meissner bodies. Histologically, these bodies were in contact with neoplastic Schwann cells. The Meissner bodies were immunopositive for S-100 protein, neuron-specific enolase, and vimentin, but were negative for calretinin. CD34-positive spindle cells were observed around the Meissner bodies. No recurrence or signs of other tumors have been observed in the patient for 5 years after tumor resection.</p> <p>Conclusion</p> <p>To the best of our knowledge, no formal descriptions of sporadic, solitary neurofibromas containing numerous Meissner bodies occurring in the oral cavity are available in literature. We believe that an uncommon proliferation of Meissner bodies, as seen in the present case, may result from aberrant differentiation of neoplastic Schwann cells.</p

Polycystic ovary syndrome

The document attached has been archived with permission from the editor of the Medical Journal of Australia. An external link to the publisher’s copy is included.Polycystic ovary syndrome (PCOS) affects 5-20% of women of reproductive age worldwide. The condition is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology (PCOM) - with excessive androgen production by the ovaries being a key feature of PCOS. Metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinaemia is evident in the vast majority of affected individuals. PCOS increases the risk for type 2 diabetes mellitus, gestational diabetes and other pregnancy-related complications, venous thromboembolism, cerebrovascular and cardiovascular events and endometrial cancer. PCOS is a diagnosis of exclusion, based primarily on the presence of hyperandrogenism, ovulatory dysfunction and PCOM. Treatment should be tailored to the complaints and needs of the patient and involves targeting metabolic abnormalities through lifestyle changes, medication and potentially surgery for the prevention and management of excess weight, androgen suppression and/or blockade, endometrial protection, reproductive therapy and the detection and treatment of psychological features. This Primer summarizes the current state of knowledge regarding the epidemiology, mechanisms and pathophysiology, diagnosis, screening and prevention, management and future investigational directions of the disorder.Robert J Norman, Ruijin Wu and Marcin T Stankiewic
