Mandibular talon cusp - a case report
Talon cusp is a relatively rare developmental dental anomaly, characterized by cusp-like projections from the cingulum area, or cemento-enamel junction of maxillary or mandibular anterior teeth, in both the primary and permanent dentition. In most of the cases it involves maxillary lateral incisors. The anomaly has been reported to be rare especially when it occurs on mandibular teeth. This article reports a case of talon cusp on permanent mandibular central incisor, which makes it a rare entity.</jats:p
Spontaneous angina bullosa hemorrhagica of tongue: An unusual problem following prosthodontic procedure
Introduction: Angina Bullosa Hemorrhagica (ABH) is the term used to describe benign subepitilial oral mucosal blood filled blisters, which are not attributed to any systemic disorder. It is a very uncommon condition, mostly seen in elderly patients. The exact etiopathogenesis of the ABH is not known. Herewith, we present a case of 50-year-old male patient who developed ABH on right lateral border of the tongue, following prosthodontics impression making for completely edentulous mouth. Methods: The case management method was topical application of chlorhexidine gel (1%) and lignocaine gel (2%) with avoidance of hot and spicy food. Result and discussion: After one week in treating with topical therapy, the lesion became normal. The diagnosis of ABH is difficult in patients because of its asymptomatic nature. The early diagnosis of the lesion is very important as a rapidly expanding blood-filled bulla in the oropharynx can cause upper airway obstruction. Therefore, a high level of suspicion is warranted on part of dentists who may the first to encounter the lesion. Conclusion: Spontaneous Angina Bullosa Hemorrhagica of tongue was an unusual problem that can occur following prosthodontic procedure. The management of the lession were intended to reduce pain or discomfort and prevent secondary infections
Coronavirus Disease 2019 (COVID-19): a new challenge in untreated wastewater
COVID-19 outbreak was declared a pandemic by the WHO on 12 March 2020. As of 27 May 2020, WHO statistics exhibited that more than five million confirmed cases have been reported globally. Much remains unclear about the fate and impact of SARS-CoV-2, the novel coronavirus 2019, in wastewater. SARS-CoV-2 infection, the etiologic agent of the current COVID-19 pandemic, is followed by virus shedding in the stool. The quantification of SARS-CoV-2 in wastewater, therefore, enables monitoring of the prevalence of infections among the population through wastewater-based epidemiology. This review discusses the possible spread of the SARS-CoV-2 virus in wastewater and its impact on human health, if any. The information and resources outlined in this paper are based on recently published studies and provide information to decision-makers on the successful management of COVID-19 and reduce the risk of human exposure to COVID-19. Additionally, systems-based approaches to curtail COVID-19 spread are also discussed.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Fall in Vitamin D Levels during Hospitalization in Children
Plasma levels of 25-hydroxyvitamin D [25(OH)D] were measured by competitive Electrochemiluminescence Immunoassay (ECLIA) in 92 children (67 boys, 25 girls) aged 3 months to 12 years at admission to hospital (timepoint 1, T1) and at discharge (timepoint 2, T2). There was a significant fall in the mean 25(OH)D from T1 (71.87 ± 27.25 nmol/L) to T2 (49.03 ± 22.25 nmol/L) (mean change = 22.84 nmol/L, P value = 0.0004). Proportion of patients having VDD (levels <50 nmol/L) at admission (25%, 23/92) increased significantly at the time of discharge (51.09%, 47/92) (P=0.0004). There was a trend towards longer duration of hospital stay, requirement of ventilation and inotropes, development of healthcare-associated infection, and mortality in vitamin D deficient as compared to nondeficient patients though the difference was statistically insignificant. In conclusion, vitamin D levels fall significantly and should be monitored during hospital stay in children. Large clinical studies are needed to prospectively evaluate the effect of vitamin D supplementation in vitamin D deficient hospitalized children on various disease outcome parameters
Efficiency and equity considerations in pricing and allocating irrigation water
Economic efficiency has to do with how much wealth a given resource base can generate. Equity has to do with how that wealth is to be distributed in society. Economic efficiency gets far more attention, in part because equity considerations involve value judgements that vary from person to person. The authors examine both the efficiency and the equity of different methods of pricing irrigation water. After describing water pricing practices in a number of countries, they evaluate their efficiency and equity. In general they find that water use is most efficient when pricing affects the demand for water. The volumetric, output, input, tiered, and two-part tariff schemes all satisfy this condition and can be efficient although whether efficiency is short-run or long-run, first- or second-best, varies. Pricing schemes that do not directly influence water input -- per-unit areas fees for example -- lead to inefficient allocation. But they are usually easier to implement and administer and require less information. The extent to which water pricing methods can effect income redistribution is limited, the authors conclude. Disparities in farm income are mainly the result of factors such as farm size and location and soil quality, but not water (or other input) prices. Pricing schemes that do not involve quantity quotas cannot be used in policies aimed at affecting income inequality. The results somewhat support the view that water prices should not be used to effect income redistribution because water prices are a poor vehicle for reducing income inequality. But pricing schemes that involve water quota rules can reduce income inequality. The authors demonstrate this with a two-rate tiered pricing scheme combined with equal quotas of the cheaper water.Water Conservation,Environmental Economics&Policies,Water and Industry,Drylands&Desertification,Economic Theory&Research,Town Water Supply and Sanitation,Water Supply and Sanitation Governance and Institutions,Water Conservation,Water and Industry,Environmental Economics&Policies
You stab my back, I'll stab yours: Management experience and perceptions of organization political behaviour
This paper reports the findings of a survey of 250 British managers, exploring
their experience and perceptions of organization politics. Political behaviour
appeared to be common. Most managers viewed political behaviour as ethical and
necessary, and aspects of organizational effectiveness, change, resourcing and
reputation were attributed to political tactics, although 80% had no training in
this area. Tactics experienced frequently included networking, using 'key
players' to support initiatives, making friends with power brokers, bending the
rules, and self-promotion. Tactics experienced as rare, but not unknown,
included misinformation, spreading rumours, and keeping 'dirt files' for
blackmail. A consistent pattern of responses concerning willingness to engage in
politics, the need to act ruthlessly and the appropriateness of reciprocity when
faced with political behaviour implies an attitude of 'you stab my back, I'll
stab yours'. Findings are discussed using an
'antecedents–behaviours–consequences' framework of perceived organization
politics to guide rese
Correction: Comparative Evaluation of GenoType MTBDR Line Probe Assay with Solid Culture Method in Early Diagnosis of Multidrug Resistant Tuberculosis (MDR-TB) at a Tertiary Care Centre in India.
Comparative evaluation of GenoType MTBDRplus line probe assay with solid culture method in early diagnosis of multidrug resistant tuberculosis (MDR-TB) at a tertiary care centre in India.
The objectives of the study were to compare the performance of line probe assay (GenoType MTBDRplus) with solid culture method for an early diagnosis of multidrug resistant tuberculosis (MDR-TB), and to study the mutation patterns associated with rpoB, katG and inhA genes at a tertiary care centre in north India.In this cross-sectional study, 269 previously treated sputum-smear acid-fast bacilli (AFB) positive MDR-TB suspects were enrolled from January to September 2012 at the All India Institute of Medical Sciences hospital, New Delhi. Line probe assay (LPA) was performed directly on the sputum specimens and the results were compared with that of conventional drug susceptibility testing (DST) on solid media [Lowenstein Jensen (LJ) method].DST results by LPA and LJ methods were compared in 242 MDR-TB suspects. The LPA detected rifampicin (RIF) resistance in 70 of 71 cases, isoniazid (INH) resistance in 86 of 93 cases, and MDR-TB in 66 of 68 cases as compared to the conventional method. Overall (rifampicin, isoniazid and MDR-TB) concordance of the LPA with the conventional DST was 96%. Sensitivity and specificity were 98% and 99% respectively for detection of RIF resistance; 92% and 99% respectively for detection of INH resistance; 97% and 100% respectively for detection of MDR-TB. Frequencies of katG gene, inhA gene and combined katG and inhA gene mutations conferring all INH resistance were 72/87 (83%), 10/87 (11%) and 5/87 (6%) respectively. The turnaround time of the LPA test was 48 hours.The LPA test provides an early diagnosis of monoresistance to isoniazid and rifampicin and is highly sensitive and specific for an early diagnosis of MDR-TB. Based on these findings, it is concluded that the LPA test can be useful in early diagnosis of drug resistant TB in high TB burden countries
