Abstract
Polymyositis (PM) is an uncommon inflammatory disease of unknown cause, but the disease shares many characteristics with autoimmune disorders. In the past, the diagnosis criteria for PM depended primarily on clinical features, blood enzyme levels, an electromyogram, and muscle biopsies. However, there are still imperfections in the diagnostic criteria of PM. The development of muscle imaging led to revisiting not only the PM diagnosis strategy but also the patients' follow-up. Teaching point: PM should be considered and included in the differential diagnosis of a patient with inflammatory signs and muscular pain, and the radiologist should be aware of its imaging features.

Multicenter RCT on Intensive Caries Prevention for Children Undergoing Dental General Anaesthesia: Intensive caries prevention for children undergoing dental general anaesthesia. J Dent 2022; 118:104057. [PMID: 35121137 DOI: 10.1016/j.jdent.2022.104057] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Revised: 01/27/2022] [Accepted: 01/31/2022] [Indexed: 10/19/2022] Open
Abstract
OBJECTIVES Early childhood caries is a persistent problem often leading to dental treatment under general anaesthesia (GA). Thus, this study investigated the effect of two additional individual caries prevention appointments before and after GA. MATERIALS AND METHODS In this multi-center, 2-arm randomized, controlled clinical trial, 408 children (age 2-5 years, mean 4.2±1.04) intended for GA were recruited and randomly assigned to the intervention and control groups with or without two additional intensive oral hygiene appointments before and after the GA. At baseline and at 6-/12-months follow-ups, approximal plaque index (API), gingival sulcus bleeding index (SBI), caries experience (dmft/s) and initial caries were recorded. RESULTS Participants in test group and control group (ITT; n=161 vs. n=147) as well as drop-outs in test and control groups (n=40 vs. n=58) showed no statistical significant difference in baseline characteristics. Test and control groups showed equivalent baseline oral health parameters (API: 78 and 77%, SBI: 22.6 and 23.5%, dmft: 8.5 and 8.2, respectively), which continuously improved during the study. The test group exhibited statistically significant greater improvement (API: 42%, SBI: 7%) than the control (API: 54%, OR: 0.48; P=0.003; SBI: 12%, OR=0.44; P=0.005). Due to the robust rehabilitation with predominantly stainless steel crowns and extractions, caries incidence was minimal and, therefore, without statistical significance (mean increase dt, test: 0.5, control: 0.6; P=0.68), which was also true for new initial carious lesions (mean increase test: 0.8 vs. control: 0.9; P=0.55). CONCLUSIONS Additional preventive sessions for children undergoing treatment under GA improved their oral hygiene parameters signifiqantly. CLINICAL SIGNIFICANCE Intensive caries prevention appointments for children receiving dental treatment under GA improved their oral hygiene and might reduce their caries risk.

Abstract
Abstract
Aim
The coronavirus disease 19 (COVID-19) pandemic has driven unprecedented restriction of the National Health Service to accommodate additional pressures. Our aim was to analyse the impact of COVID-19 on the largest colorectal cancer (CRC) services in NHS Greater Glasgow & Clyde.
Method
Audit data collected from multidisciplinary team meetings for South Glasgow CRC service were accessed. We compared April-June 2020 (‘Lockdown group’) to corresponding months in 2019 (‘Control group’). Statistical analysis by unpaired T-test, Pearson’s χ2 test with post hoc analysis using adjusted Z scores and Bonferroni correction as appropriate.
Results
There was a 39.5% reduction in CRC diagnoses during lockdown (n = 49) compared to control (n = 81). There was a 34.1% reduction in CRC operations during lockdown (n = 27) compared to control (n = 52). The proportion of patients managed operatively did not differ between groups (p = 0.140). There was no difference in the number of days from diagnosis to first treatment between Lockdown and Control groups (Mean(SD): 40.1±35.3 and 43.2±42.9, p = 0.257). Primary care physicians were the main referral source for both lockdown (52%) and control groups (46%). The cessation of bowel screening programme saw no referrals in lockdown whereas it accounted for 21% of referrals in control group, p < 0.001).
Conclusions
We experienced dramatic reductions in CRC diagnoses during lockdown that was not only accounted for by the cessation of bowel screening. The diagnostic delay in the 39.5% ‘missed’ CRC patients may result in patient morbidity; a severe repercussion of COVID-19. The resurgence of COVID-19 cases poses a real threat to cancer services.

Fixed-dose combination in management of type 2 diabetes mellitus: Expert opinion from an international panel. J Family Med Prim Care 2020; 9:5450-5457. [PMID: 33532378 PMCID: PMC7842427 DOI: 10.4103/jfmpc.jfmpc_843_20] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Revised: 06/14/2020] [Accepted: 08/03/2020] [Indexed: 01/08/2023] Open
Abstract
Type 2 diabetes mellitus (T2DM) is a progressive disease with multifactorial etiology. The first-line therapy includes monotherapy (with metformin), which often fails to provide effective glycemic control, necessitating the addition of add-on therapy. In this regard, multiple single-dose agents formulated as a single-dose form called fixed-dose combinations (FDCs) have been evaluated for their safety, efficacy, and tolerability. The primary objective of this review is to develop practice-based expert group opinion on the current status and the causes of concern regarding the irrational use of FDCs, in Indian settings. After due discussions, the expert group analyzed the results from several clinical evidence in which various fixed combinations were used in T2DM management. The panel opined that FDCs (double or triple) improve patient adherence, reduce cost, and provide effective glycemic control and, thereby, play an important role in the management of T2DM. The expert group strongly recommended that the irrational metformin FDC's, banned by Indian government, should be stopped and could be achieved through active participation from the government, regulatory bodies, and health ministry, and through continuous education of primary care physicians and pharmacists. In T2DM management, FDCs play a crucial role in achieving glycemic targets effectively. However, understanding the difference between rational and irrational FDC combinations is necessary from the safety, efficacy, and tolerability perspective. In this regard, primary care physicians will have to use a multistep approach so that they can take informed decisions.

Abstract
OBJECTIVES To assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to compare these findings with the German resident population. METHODS This multicenter cross-sectional study recruited 544 refugees aged 3-75+ years; they were examined at ten registration institutions in four federal states in Germany by two calibrated dentists. The refugees were screened for caries (dmft/DMFT) and its complications (pufa/PUFA); this data was compared to the resident population via the representative national oral health surveys). RESULTS The deciduous dentition of the 3-year-old refugees had a mean dmft value of 2.62 ± 3.6 compared with 0.48 dmft in the German resident population, and caries increased to 5.22 ± 3.4 for 6-7-year-olds (Germany: 1.73 dmft). Few refugee children had naturally healthy teeth (7% in 6-7-year-olds, Germany: 56%). In the permanent dentition, the gap in caries prevalence between refugees and the German population decreased with age (35-44-year-olds: 10.55 ± 7.1 DMFT; Germany: 11.2), but refugees exhibited more caries defects (35-44-year-olds DT = 3.13 ± 3.0; Germany: 0.5). German residents had more restorations (35-44-year-olds FT = 4.21 ± 4.6). Regarding complications, the 6-7-year-olds exhibited the highest pufa index (0.86 ± 1.4) which decreased in adolescence (13-17-year-olds, 0.18 ± 0.6) and increased in adults (45-64-year-olds, 0.45 ± 0.8). CONCLUSION The refugees had high caries experience, often untreated caries teeth and more complications compared with the German resident population, especially in children. Closing this gap by extending preventive systems to the refugees would decrease future treatment needs. CLINICAL RELEVANCE European countries should be prepared for the higher dental treatment needs in recent refugees, especially in children.

Unravelling the utility of modern sulfonylureas from cardiovascular outcome trials and landmark trials: expert opinion from an international panel. Indian Heart J 2020; 72:7-13. [PMID: 32423565 PMCID: PMC7231843 DOI: 10.1016/j.ihj.2020.01.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 12/25/2019] [Accepted: 01/05/2020] [Indexed: 12/13/2022] Open
Abstract
AIM The primary objective of this review is to develop practice-based expert group opinions on the cardiovascular (CV) safety and utility of modern sulfonylureas (SUs) in cardiovascular outcome trials (CVOTs). BACKGROUND The United States Food and Drug Administration issued new guidance to the pharmaceutical industry in 2008 regarding the development of new antihyperglycemic drugs. The guidance expanded the scope for the approval of novel antihyperglycemic drugs by mandating CVOTs for safety. A few long-term CVOTs on dipeptidyl peptidase 4 inhibitors, glucagon-like peptide 1 receptor agonists, and sodium-glucose cotransporter 2 inhibitors have been completed, while others are ongoing. SUs, which constitute one of the key antihyperglycemic agents used for the management of type 2 diabetes mellitus (T2DM), have been used as comparator agents in several CVOTs. However, the need for CVOTs on modern SUs remains debatable. In this context, a multinational group of endocrinologists convened for a meeting and discussed the need for CVOTs of modern SUs to evaluate their utility in the management of patients with T2DM. At the meeting, CVOTs of modern SUs conducted to date and the hypotheses derived from the results of these trials were discussed. REVIEW RESULTS The expert group analyzed the key trials emphasizing the CV safety of modern SUs and also reviewed the results of various CVOTs in which modern SUs were used as comparators. Based on literature evidence and individual clinical insights, the expert group opined that modern SUs are cardiosafe and that since they have been used as comparators in other CVOTs, CVOTs of SUs are not required. CONCLUSION Modern SUs can be considered a cardiosafe option for the management of patients with diabetes mellitus and CV disease; thus CVOTs among individuals with T2DM are not required.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TAVI) has been associated with increases in markers of myocardial injury but underlying mechanisms as well as relevance for prosthesis hemodynamics, cardiac function and clinical outcome remain unclear.
Purpose
To study the trajectory of high-sensitivity troponin T (hs-TnT) during TAVI and elucidate putative associations with demographics, anatomical and procedural features, as well as clinical and echocardiographic outcome.
Methods
This prospective real-world registry study included all patients (n=275) undergoing transfemoral TAVI using a self-expanding or balloon-mounted system at a large tertiary university hospital over the most recent three-year period. Plasma levels of hs-TnT (reference level 0–14 ng/l) at 24 hours (h) before TAVI and at 9h, 18h, 30h, 42h and 72h after TAVI were analyzed. Patients with ongoing myocardial ischemia and acute coronary syndrome were excluded. We studied the association between hs-TnT values and patient characteristics, echocardiographic and CT findings at baseline as well as procedural features including the use of pre- and postdilatation. Moreover, we studied the association between hs-TnT and and echocardiography and clinical outcome at 1 year after TAVI.
Results
In this real-world TAVI cohort (median age 83.2±0.2 years; 48.7% women; 5.2±0.2 comorbidities; eGFR 58.0±6.0 ml/min/1.73m2; mean±standard error), 100% of patients exhibited significant elevations of hs-TnT at approximately 9-fold (207.0±11.0) compared to baseline (23±0.2 ng/L, median±SE). Peak hs-TnT values were reached at 9 h post-TAVI (207±11 ng/L) with subsequent gradual decline (figure). Myocardial injury was confirmed by elevated creatin kinase (CK) and CKMB isozyme. No significant association was found between peak hs-TnT, delta hs-TnT (peak minus baseline values) or area under the curve (AUC) of hs-TnT on the one hand, and patient demographics including renal dysfunction, comorbidity, age and gender on the other side. Moreover, no significant association between hs-TnT and anatomical features, prosthesis sizing, or use of pre- and postdilatation was found. No association between hs-TnT during TAVI and NYHA functional class, transvalvular pressure gradient, cardiac function or survival at 1 year was found. In subjects with at least one year of follow-up after TAVI (n=138), NYHA functional class (1.7 vs 2.7) and NT-proBNP plasma levels (1126±316 vs 1581±563 ng/L) were significantly lower compared to pre-TAVI.
Conclusions
Modest transient elevations of hs-TnT occur in all patients undergoing TAVI and are consistent with subtle myocardial injury. The lack of significant association between the extent of myocardial injury during TAVI and clinical and hemodynamic outcome as well as all-cause mortality is reassuring for current real-world practice.

Abstract
BACKGROUND In Australia, correspondence is routinely sent to general practitioners following a specialist consultation. Written communication is an important way to enhance patient experiences and understanding, yet most patients do not receive copies of their medical correspondence. AIMS To determine whether providing clinic correspondence and endoscopy reports to patients leads to improved understanding, satisfaction or anxiety. METHODS This is a prospective, randomised controlled study conducted at an Australian tertiary hospital from October 2013 to February 2015. New adult referrals to the general gastroenterology clinic requiring an urgent endoscopic procedure were eligible for the study. The intervention group received a copy of their clinic correspondence and endoscopy report, while the control group received neither. Participants completed questionnaires, including visual analogue scales and the Hospital Anxiety and Depression Scale, at three time points. Primary outcomes were patient understanding, anxiety and satisfaction. RESULTS A total of 70 participants was included in the study. There was no reduction in anxiety levels (P = 0.52), no increase in understanding (P = 0.73) or any increase in satisfaction (P = 0.33) in participants receiving correspondence. However, 97% of participants indicated that they wished to receive correspondence in the future, and 94% of participants in the correspondence group reported that receiving correspondence had helped them to understand their medical condition. CONCLUSION Patients wish to receive copies of their correspondence and feel it improves their understanding of their medical condition. Although we were unable to demonstrate a measurable reduction in anxiety, increase in understanding or satisfaction, we recommend that patients be offered the choice of receiving copies of their clinic correspondence and endoscopy reports.

Abstract
AIM To investigate dental students' educational experience, attitudes and knowledge with regard to child physical abuse in all dental schools in United Arab Emirates. METHODS The data were collected by self-administered structured questionnaire completed by 578 under graduate dental students in four (all) dental schools in United Arab Emirates. Data were analysed using descriptive analyses for responses to each question. RESULTS The results indicated that there was lack of knowledge of reporting procedure, signs of physical abuse and social indicators among all respondents. Over 80 % of the students agreed that dentists should be legally mandated to report abuse cases and a high percentage (94.3 %) of the participants believed they had an ethical duty to report child abuse. Most students indicated that their dental school was the main source of information on this topic. The majority of the respondents expressed a need for further training. CONCLUSIONS Dental students were not sufficiently prepared to know what to look for when they suspect child abuse and what to actually do when they encounter this problem in a professional setting. To provide better care for these young domestic violence victims, dental schools' curriculum modifications should focus on providing students with concrete educational experiences regarding child abuse cases.

Abstract
Ocular examination should be a part of the routine assessment of the patients seen at sexually transmitted diseases (STD) clinics due to the importance of these organs in the general wellbeing of patients. It is essential to keep an open eye on ocular signs and symptoms of patients with a history of exposure to common STD pathogens, to ensure prompt investigation and management of ocular complications of the STDs, which, if left unnoticed, otherwise could subject the patients to a great deal of anxiety and distress.

Abstract
The early diagnosis and treatment of ocular disease to prevent morbidity and mortality of patients with human immunodeficiency virus (HIV) is of paramount importance. Since the advent of highly active antiretroviral therapy (HAART), the incidence of ocular complications of HIV has decreased and their manifestations and natural course are also modified. This has been observed in the face of emerging immune recovery, which per se has brought new difficulties in the process of diagnosing and management of the ocular disease. Conditions such as immune recovery uveitis could affect eyes with history of opportunistic disease with a potential to cause vision loss; with this regard, differentiation of the inflammatory process from infective causes is essential. The other sexually contracted diseases are also to be included in this complex picture because of their contribution to the clinical picture and also sharing common routes of transmission with HIV. There is very little doubt that visual deterioration would further deteriorate the already compromised quality of life of this group of patients. In this review, authors wish to provide evidence available in the medical literature around the visual health issues in HIV-infected patients and raise awareness towards the changing pattern of the ocular disease in the HAART era.

Abstract
BACKGROUND The association between Guillain-Barre syndrome (GBS) and malignancy is uncommon and has not been previously reported in gynecological cancers. CASE Our case documents this syndrome occurring in a patient shortly after completion of adjuvant chemo-radiotherapy for endometrial carcinoma. We review the current literature and discuss potential pathogenic mechanisms of this likely paraneoplastic association. CONCLUSION GBS in cancer patients is a potentially life-threatening condition and should be differentiated from simple chemotherapy toxicity, particularly as effective treatment is available.

Abstract
This paper presents a new classifier combination technique based on the Dempster-Shafer theory of evidence. The Dempster-Shafer theory of evidence is a powerful method for combining measures of evidence from different classifiers. However, since each of the available methods that estimates the evidence of classifiers has its own limitations, we propose here a new implementation which adapts to training data so that the overall mean square error is minimized. The proposed technique is shown to outperform most available classifier combination methods when tested on three different classification problems.

Abstract
The respiration and fermentation rates were compared in germinating seeds of 12 different cultivated species from five families. In air, fermentation contributes significantly to the energy metabolism only in some species (pea, maize), but is generally negligible when compared to respiration. The fermentation rate under anoxia was related either to the metabolic activity under air or to the adenine nucleotide content of the seeds: it was generally higher in seeds which contain starchy reserves (rice, maize, sorghum, pea), than in seeds which do not contain starch (lettuce, sunflower, radish, turnip, cabbage, flax); however, it was similar in wheat, sorghum (starchy seeds), and soya (nonstarchy seeds). The value of the energy charge of all the seeds was lower under anoxia than in air: after 24 hours under anoxia, it was higher than 0.5 in the starchy seeds and in soya and it was around 0.25 in the other fatty seeds.

Abstract
The effect of O(2) partial pressure on the germination and the respiration of 12 cultivated species was studied. The reciprocal of the time necessary to observe rootlet emergence in 50% of the seeds was used to approach the germination rate. The maximum germination and respiration rates were reached in most seeds at O(2) pressures close to that of air. Decreasing the O(2) pressure produced a gradual decrease of the germination rate. The seeds could be classed in two groups according to their response to low O(2) pressures. Group I includes lettuce, sunflower, radish, turnip, cabbage, flax, and soybean: at O(2) pressures close to 2 kilopascals, the germination in this group was stopped and the adenylate energy charge was lower than 0.6. Group II includes rice, wheat, maize, sorghum, and pea. The germination rate of these seeds was also gradually decreased by lowering the O(2) partial pressure but germination still occured, very slowly, at 0.1 kilopascal; the adenylate energy charge remained higher than 0.6. These differences in the germination rates and adenylate energy charge values could not be explained by differences in the sensitivity of respiration to O(2).
