RESUMEN
Introduction: Stainless steel crowns (SSCs) are the popular restorative technique for the young permanent first molars treated endodontically. However, these restorations are not esthetically appealing and need replacement once adjacent teeth erupt and occlusion is stabilized. Aim: Digitally customized aesthetic restoration constitutes as a reliable approach for restoring decayed young permanent molars. Materials and methods: Here we present an innovative treatment approach for endodontically treated permanent young molars using a digital workflow with Intraoral scanners (IOS) and computer-aided design/computer-assisted manufacturing (CAD/CAM) fabrication of the restoration. IOSs include scanning of the prepared tooth, its antagonist, and the bite. CAD/CAM preparation of the customized restoration is followed by cementation and follow-up. Result: IOSs are well tolerated by children, easily and swiftly implemented. Digital workflow should be considered for endodontically treated permanent young molars in contrast to prefabricated unaesthetic options. How to cite this article: Gupta G, Gupta DK, Bhat M, et al.

RESUMEN
The aim of the study was to determine the post surgical outcomes in pediatric adenotonsillar hypertrophy with OSA using portable polysomnography (PSG), OSA 18 Questionnaire and Quality of life (QoL) scores. Secondly to correlate the subjective outcomes with objective scores of polysomonography. A prospective, single-arm, nonrandomized, single center study was performed at a tertiary care centre on children aged 3-12 years (n = 30) with adenoid hypertrophy/ tonsillar hypertrophy/adenotonsillar hypertrophy and symptoms suggestive of OSA. All subjects underwent appropriate surgical intervention. A portable PSG and OSA 18 questionnaire evaluation was performed pre surgery and 06 weeks post surgery to assess objective and clinical assessment for OSA. The mean age of children enrolled in the study was 8.68 ± 3 years. The mean pre treatment AHI was 12.56 ± 13.16 which improved to 1.72 ± 1.53 post surgery and was statistically significant (p < 0.05, Wilcoxon signed rank test). There was a statistically significant improvement in other PSG indices such as RDI and ODI post surgery also. The mean total symptom score (TSS) and QoL score also showed a statistically significant improvement post treatment (p < 0.05). However there was no correlation between the PSG and OSA 18 questionnaire scores pre and post surgery. Children with OSA like symptoms can undergo a portable polysomnography pre and post surgery to demonstrate severity of OSA and objectively monitor improvement in OSA post treatment. In the absence of availability of PSG, OSA 18 questionnaire is a suitable alternative to monitor disease severity and outcomes. Further studies may plan to include impact of paediatric OSA on other function such as the cardiac, dentition & malocclusion and neurocognitive function.
RESUMEN
The mismanagement of consumer-discarded plastic waste (CDPW) has raised global environmental concerns about climate change. The COVID-19 outbreak has generated â¼1.6 million tons of plastic waste per day in the form of personal protective equipment (masks, gloves, face shields, and sanitizer bottles). These plastic wastes are either combustible or openly dumped in aquatic and terrestrial environments. Open dumping upsurges emerging contaminants like micro-nano plastics (MNPs) that directly enter the ecosystem and cause severe impacts on flora and fauna. Therefore, it has become an utmost priority to determine sustainable technologies that can degrade or treat MNPs from the environment. The present review assesses the sources and impacts of MNPs, various challenges, and issues associated with their remediation techniques. Accordingly, a novel sustainable circular model is recommended to increase the degradation efficiency of MNPs using biochemical and biological methods. It is also concluded that the proposed model does not only overcome environmental issues but also provides a sustainable secondary resource to meet the sustainable development goals (SDGs).

In C-2W (also called "Norman") [1], beam-driven field reversed configuration plasmas embedded in a magnetic mirror are produced and sustained in a steady state. A multi-chord passive Doppler spectroscopy diagnostic provides line-integrated impurity emission measurements near the center plane of the confinement vessel with fast time resolution. The high degree of plasma non-uniformity across optical sightlines can preclude direct fitting of the measured line-integrated spectra. To overcome this challenge, local impurity profiles are inferred using Bayesian tomography, a superior analysis technique based on a complete forward model of the diagnostic. The measured emission of O4+ triplet lines near 278.4 nm is modeled assuming two independent populations: thermal and beam ions. Gaussian processes are used to generate and infer local profiles. The inference incorporates details of the geometrical arrangement of the diagnostic, instrument function, intensity calibration, and a noise model. Markov chain Monte Carlo (MCMC) sampling of the posterior distribution of solutions provides high-fidelity uncertainty estimates. The reconstructed O4+ impurity profiles are consistent with data from other diagnostics and show good agreement with expected physics based on previously developed models of biasing circuit and impurity transport.
RESUMEN
Objective: PET/CT scan has been increasingly used in assessment of Head and Neck cancer prior to treatment for evaluation and for surveillance. In this study we aim to assess the utilization of PET/CT scan at a tertiary care hospital. Methods: Retrospectively data was reviewed of all patients of Head and Neck cancer who underwent PET/CT scan for workup or for follow-up between July 2018 and December 2019. PET/CT scan done in the pre-treatment assessment and post-treatment surveillance were analyzed for its utility. Results: A total of 145 patients were included. The main indication for pre-treatment PET/CT scan was loco-regionally advanced disease (62 of 90 patients, 68.8%). No specific indication was noted in 19 patients (21%). A significant change in treatment decision was seen in pre-treatment patients based on M stage following a PET/CT scan. However, no change was noted on the basis of T or N stage. In the post-treatment surveillance there was a significant correlation of type of recurrence with clinical assessment and indication for PET/CT scan. 37 out of 87 patients (42.5%) underwent PET/CT scan for no specific reason, of which, 07 patients (18.9%) were detected to have distant metastasis. Conclusion: Role of PET/CT in the pre-treatment assessment is very limited and maybe confined to advanced local or regional disease. Post-treatment surveillance with PET/CT scan has a promising role and must be done as a baseline during 1st follow up at 03 months in all patients who have advanced disease and have undergone multi-modality treatment for the same.
RESUMEN
The role of otolaryngologist in the management of CSF rhinorrhea is expanding. It is prudent to evaluate all cases of CSF leak, understand the etiological causes and formalize a working approach to management of such cases to yield better outcome. A retrospective descriptive study of 39 cases of proven CSF rhinorrhea treated at a tertiary care center between January 2014 to August 2019. The data retrieved were analyzed for age, gender, weight, etiology, recurrence of the disease, history of meningitis, nasal or neurosurgical intervention in past, imaging inform of CT and MR cisternography as and when required. This was aimed at understanding the various etiological types of CSF rhinorrhea and work out a management approach. The patients with skullbase tumors who presented with CSF Rhinorrhea were excluded from the study sample. There were 18 cases of spontaneous CSF rhinorrhea and 20 cases of traumatic CSF rhinorrhea. The mean BMI of spontaneous gp was 32.9 ± 2.46 kg/m2 while in traumatic group was 25.7 ± 2.94 kg/m2 and difference was statistically significant. None of the spontaneous CSF rhinorrhea cases showed features of raised ICP preoperatively either clinically or on imaging except empty sella in 14 of 18 cases. 6 of 18 cases of spontaneous category while 01 of 20 cases in traumatic had recurrence and the recurrence rate was significantly (p < 0.05) higher in spontaneous group. In traumatic group 7 were iatrogenic, 8 were occult traumatic and rest were acute traumatic. 4 of traumatic and 1 spontaneous group had history of meningitis and the incidence was 12.8% in our study group. Early identification and localization of CSF fistula is necessary to reduce morbidity and mortality associated with it. Risk of meningitis is high in CSF rhinorrhea especially in traumatic group. The etiology of CSF rhinorrhea has a bearing on the management and spontaneous CSF rhinorrhea has higher rate of recurrence.
RESUMEN
The incessant population has increased the production and consumption of plastics, paper, metals, and organic materials, which are discarded as solid waste after their end of life. The accumulation of these wastes has created growing concerns all over the world. However, conventional methods of solid waste management i.e., direct combustion and landfilling have caused several negative impacts on the environment (releasing toxic chemicals and greenhouse gases, huge land use) besides affecting human health. Therefore, it is requisite to determine sustainable alternative technologies that not only help in mitigating environmental issues but also increase the economic value of the discarded solid wastes. This process is known as urban mining where waste is converted into secondary resources and thereby conserves the natural primary resources. Thus, this review highlights the technological advancements in the valorization process of discarded wastes and their sustainable utilization. We also discussed several limitations of the existing urban mining processes and further the feasibility of valorization techniques was critically analyzed from a techno-economical perspective. This paper recommends a novel sustainable model based on the circular economy concept, where waste is urban mined and recovered as a secondary resource to support the united nations sustainable development goals (SDGs). The implementation of this model will ultimately help the developing countries to achieve the target of SDGs 11, 12, and 14.

Background: Class II malocclusion is one of the most common malocclusion with varied prevalence. Functional therapy with appliances like Twin Block or Fixed functional appliances forms the mainstay of treatment in growing Class II patients. These patients might demonstrate narrow airway due to the retrognathic position of the mandible. This study investigated the effects of twin block and fixed functional appliance therapy (Forsus™ FRD) on the pharyngeal airway space in skeletal Class II patients. Methods: Forty patients with Class II malocclusion were selected and divided into two equal groups of 20 patients each for both Twin block and Forsus group. Lateral cephalograms were obtained before and after the functional appliance therapy. Evaluation was done for changes in hyoid bone position, pharyngeal airway dimensions and tongue position. Results: The variables of the study showed better hyoid position in both the groups. In Twin Block group, an increase in hy-apw2 and hy-PoFH suggested anterior positioning of hyoid and a decrease in H-MP and hy-ML indicated superior positioning. In Forsus group an increase in H-H', hy-FH, hy-ML, hy-NL, hy-NSL and hy-OL suggested inferior positioning of hyoid, while an increase in hy-apw2, hy-CVT, hy-PoFH, hy-RL and hy'-tgo indicated anterior positioning of hyoid bone after functional therapy. Conclusion: Both the twin block and Forsus™ FRD improved the position of the hyoid bone after the functional appliance therapy however the changes were not statistically significant. Twin block and Forsus™ had similar effect on the hyoid bone position, pharyngeal dimensions and the tongue position.

Material: This observational cross sectional study included 100 patients of age >12 years of all genders with chronic haemolytic anemia and history of multiple blood transfusion. Blood and radiological investigations were done. Clinical, hematological and molecular characteristics were studied. Observation and Clinical: Pallor was present in all cases and icterus in 32% cases. Total 48% of the patients had hepatomegaly and 98% had splenomegaly. Among genotypes, 15% cases had α-thalassemia, 62% had ß thalassemia + 뫧 thalassemia, 7% had HbS hemoglobinopathy, and 16% had HbE hemoglobinopathy. Hematological: Hemoglobin showed significant association with molecular genotypes of thalassemia with lowest being present in ß-thalassemia + 뫧 thalassemia and HbE.MCV showed significant association with molecular genotypes, with HbE having the lowest MCV of 65.5 fl. LDH levels showed a significant association with molecular genotype with highest being in HbS hemoglobinopathy. Molecular Characteristics: Common mutations in compound α-thalassemia were 3.7, 4.2 and 20.5 deletion. As for ß-thalassemia and 뫧 thalassemia, 47 cases had heterozygous type and 15 cases had homozygous types. In ß-thalassemia, the homozygous type showed IVS1- 5(GâC),CD 41/42(âCTT) and IVSII-654(GâT) while heterozygous type showed CD16(âG), CD 41/42(âCTT), IVS1-5(GâC), and IVSII-654(GâT) . In 뫧 thalassemia, the heterozygous type showed 뫧 inversion mutation.In HbS hemoglobinopathy, heterozygous type showed Codon 6(AâT) and compound heterozygous type showed IVS1- 5(GâC) and Codon 6(AâT). In HbE hemoglobinopathy,the homozygous type showed CD26(GâA) and compound heterozygous type showed IVS1-5(GâC) and IVSII 654(GâT). Conclusion: The common thalassemia genotypes observed in our study were α-thalassemia (15%), ß thalassemia + 뫧 thalassemia, (62%) HbS hemoglobinopathy (7%), and HbE hemoglobinopathy (16%). The patients presented with pallor, icterus, hepatomegaly, and splenomegaly which were comparable among all molecular genotypes of thalassemia and hemoglobinopathies. α-thalassemia had compound α-thalassemia with common mutations being 3.7, 4.2 and 20.5 deletion. As for ß-thalassemia and 뫧 thalassemia, 47 cases had heterozygous type and 15 cases had homozygous types. In 뫧 thalassemia, the heterozygous type showed 뫧 inversion mutation in 5 cases. MCH, Retic count, ferritin stores, and peripheral blood smear were similar in all molecular genotypes. Hemoglobin, MCV and LDH showed a significant association with molecular genotypes. Microcytic hypochromic anaemia was commonest among all.The findings of the present study show that the genotypes of thalassemia are characterized by diversity as well as significant genetic heterogeneities.

INTRODUCTION: The lengthy duration of comprehensive orthodontic treatment has always been a major concern. Various modalities have been proposed to accelerate the orthodontic tooth movement (OTM) with varying degree of success. However, there is limited literature, comparing the efficiency of two commonly used modalities which are relatively simple, safe and comfortable chair-side procedures to accelerate orthodontic tooth movement viz. Photo-biomodulation (PBM) being non-invasive and micro-osteoperforations (MOPs) being minimally invasive. The aim was to evaluate the comparative effect of PBM and MOPs on the rate of orthodontic tooth movement (OTM). METHODS: In this split mouth study, thirty patients requiring ma-xillary first premolar extraction were randomly allocated for Photo-biomodulation (PBM) on one side and for micro-osteoperforations (MOPs) on other side of maxilla. Separate canine retraction was performed and movement was measured over a three month period. RESULTS: Micro-osteoperforations (MOPs) significantly increased the rate of maxillary canine retraction by 1.1 fold when compared to the Photo-biomodulation (PBM).The MOPs can successfully reduce the comprehensive fixed orthodontic treatment time by around 9% as compared to PBM. CONCLUSIONS: Micro-osteoperforation is a more efficient modality of accelerating tooth movement as compared to Photo-biomodulation which can be used in routine orthodontic practice.

The interest in the working and functionality of the human gut microbiome has increased drastically over the years. Though the existence of gut microbes has long been speculated for long over the last few decades, a lot of research has sprung up in studying and understanding the role of gut microbes in the human digestive tract. The microbes present in the gut are highly instrumental in maintaining the metabolism in the body. Further research is going on in this field to understand how gut microbes can be employed as potential sources of novel therapeutics; moreover, probiotics have also elucidated their significant place in this direction. As regards the clinical perspective, microbes can be engineered to afford defence mechanisms while interacting with foreign pathogenic bodies. More investigations in this field may assist us to evaluate and understand how these cells communicate with human cells and promote immune interactions. Here we elaborate on the possible implication of human gut microbiota into the immune system as well as explore the probiotics in the various human ailments. Comprehensive information on the human gut microbiome at the same platform may contribute effectively to our understanding of the human microbiome and possible mechanisms of associated human diseases.

BACKGROUND: There is a paucity of data on risk factors for infection among healthcare workers (HCWs) from India. Our objective was to evaluate the risk factors and frequency of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among HCWs. METHODS: We conducted this retrospective case-control study of 3100 HCWs between May and July 2020. HCWs positive for SARS-CoV-2 infection were the cases (n=506) and those negative for SARS-CoV-2 were the controls (n=253). Univariate analysis was followed by multivariate analysis of key demographic, clinical and infection control variables. RESULTS: SARS-CoV-2 infection was found in 16.32% of HCWs. Nearly 45% of infected HCWs were asymptomatic. The proportions of sanitation workers (24% vs 8%; p<0.0001) and technicians (10% vs 4%; p=0.0002) were higher and that of doctors was lower among cases as compared with controls (23% vs 43%; p<0.0001). On univariate analysis, the type of HCW, smoking, lack of training, inadequate personal protective equipment (PPE) use and taking no or fewer doses of hydroxychloroquine (HCQ) were found to be significant. On multivariate analysis, the type of HCW (risk ratio [RR] 1.67 [95% confidence interval {CI} 1.34 to 2.08], p<0.0001), inappropriate PPE use (RR 0.63 [95% CI 0.44 to 0.89], p=0.01) and taking fewer doses of HCQ (RR 0.92 [95% CI 0.86 to 0.99], p=0.03) were significant. CONCLUSIONS: The frequency of SARS-CoV-2 infection was 16% among HCWs. Being a sanitation worker, inappropriate PPE use and lack of HCQ prophylaxis predisposed HCWs to SARS-CoV-2 infection.

Various new clinical signs and symptoms, such as dysfunction of smell (anosmia) and taste (dysgeusia) have emerged ever since the coronavirus disease 2019 (COVID-19) pandemic begun. The objective of this study was to identify the clinical presentation and factors associated with 'new loss/change of smell (anosmia) or taste (dysgeusia)' at admission in patients positive by real time polymerase chain reaction for SARS-CoV-2 infection. All adult COVID-19 patients with new onset anosmia or dysgeusia at admission were included in study group. Equal number of age and gender matched COVID-19 patients without anosmia or dysgeusia at admission were included in the control group. A total of 261 COVID-19 patients were admitted during the study period of which 55 (21%) had anosmia and or dysgeusia. The mean (SD) age was 36 (13) years and majority were males (58%, n = 32). Comorbidity was present in 38% of cases (n = 21). Anosmia and dysgeusia were noted in more than 1/5th of the cases. Anosmia (96%, n = 53) was more common than dysgeusia (75%, n = 41). Presence of both ansomia and dysgeusia was noted in 71% of patients (n = 39). On comparing the cases with the controls, on univariate analysis, fever (higher in cases), rhinitis (lower in cases), thrombocytopenia, elevated creatinine and bilirubin (all higher in cases) were significantly associated with anosmia or dysgeusia. On multivariate analysis, only rhinitis (odds ratio [OR]: 0.28; 95% confidence interval [CI]: 0.09-0.83; p = .02) thrombocytopenia (OR: 0.99; 95% CI: 0.99-0.99; p = .01) and elevated creatinine (OR: 7.6; 95% CI: 1.5-37.6; p = .01) remained significant. In this retrospective study of COVID-19 patients, we found anosmia and dysgeusia in more than 1/5th of the cases. Absence of rhinitis, low platelet counts and elevated creatinine were associated with anosmia or dysgeusia in these patients.

Haemolytic anaemia is a commonly encountered condition in clinical haematology practise. Dissecting the aetiology of haemolytic anaemia is of paramount importance for appropriate management. We describe a 29-years-old lady of Indian origin, who presented with fatigue and recurrent jaundice for 2 years. Examination revealed pallor, mild icterus, and splenomegaly. Blood tests showed anaemia, reticulocytosis, indirecthyperbilirubinemia, and high serum lactate dehydrogenase, consistent with haemolytic anaemia. Peripheral smear showed severely microcytic hypochromic red cells and polychromasia. Heinz bodies and inclusion bodies were seen with supravital staining. Haemoglobin high pressure liquid chromatography showed low HbA2 and normal HbF. Work-up for iron deficiency was negative. Polymerase chain reaction of the genomic DNA failed to identify common deletions in the HBA genes. Sangers sequencing of HBA2 gene revealed a homozygous missense mutation NM_000517.6: c.391G > C (p.Ala131Pro) leading to a highly unstable hemoglobin, Hb Sun Prairie. Mother was heterozygous for the same mutation, and father was unavailable for genetic testing. We highlight the role of sangers sequencing in unravelling the underlying aetiology of haemolytic anaemia. Pathophysiology and existing literature of Hb Sun Prairie has been discussed.

In this work, we have studied sorption of 137Сs and 90Sr radionuclides from seawater under batch conditions by ferrocyanide sorbents based on hydrated titanium and zirconium dioxides (Т-35, NPF-HTD), clinoptilolite and glauconite (NPF-GL, NPF-CL) natural aluminosilicates, zirconium phosphate (T-3A), modified hydrated titanium dioxide (T-3K) as well as by manganese dioxide based on hydrated titanium dioxide (MD-HTD). Isotherms of sorption and dependences of cesium distribution coefficients on salt content and calcium concentration were obtained. Distribution coefficients of cesium and strontium were calculated. Stability of spent sorbents against radionuclides leaching was studied in from the point of view of their further treatment. The NPF-GL and NPF-HTD sorbents are recommended for treatment of seawater-based liquid radioactive waste with various salinity; these sorbents possess high distribution coefficients of cesium 104 and 105 ml/g even at the salinity of waste as high as 100 g L-1. Distribution coefficients of strontium from seawater were (1.0-1.9)·102 ml/g for all sorbents that is conditioned by the presence of colloidal species of strontium (34 ± 7%) in the simulated seawater. Capacities of the sorbents for strontium varied within 200-310 mg/g. The sorbents strongly retain adsorbed radionuclides: the total percentage of leaching for 28 days was 4.4%, 2.2% and 3.1% for 137Cs leaching from the NPF-HTD, T-35 and T-3A sorbents respectively and 10.7% for 90Sr leaching from the NPF-CL sorbent.
