Abstract
Background The aim of this study is to evaluate the location and radio morphometric features of the posterior superior alveolar artery (PSAA) in patients undergoing rehabilitation of posterior maxilla and other sinus augmentation surgical procedures by cone-beam computed tomography (CBCT). Materials and Methods A total of 816 CBCT scans were included. Various radio morphometric measurements were done to assess the PSAA location, diameter, and distances to the sinus floor and alveolar crest. Results The PSAA was mostly intraosseous in the maximum in the age group 31-51 years (56%), in males (53.4%), and in dentate patients (57.4%). The artery tends to be wider in older patients. Distances to the sinus floor or the alveolar crest tend to be shorter in women. Conclusions This study suggests that CBCT is a valuable pre-surgical tool and the evaluation of the PSAA on CBCT images could reduce the likelihood of excess bleeding during surgery in the maxillary posterior region.

Abstract
Aim Urine as a biofluid has been rarely used as a diagnostic fluid in oral diseases. The article aims to systematically review the utility of human urinary carcinogen metabolites as an approach for obtaining important information about tobacco and cancer. Materials and Methods The following article reviews the use of urine and its metabolites as biomarkers in various lesions of the oral cavity including oral squamous cell carcinoma and as a screening method in evaluating tobacco and its components. A bibliographic comprehensive search was carried out in the main databases: PUBMED, SciELO, Google Scholar, VHL, and LILACS for articles that were published from 1985 to 2020. The inclusion criteria were "urinary metabolites," "oral cancer/HNSCC," "body fluids," "tobacco," and "metabolomics." A total of 55 articles were collected which included laboratory studies, systematic reviews, and literature of urinary metabolites in tobacco users. Results Most of the studies carried out show accurate results with high sensitivity of urinary metabolite biomarkers in individuals with tobacco-based habits and lesions caused by them. Conclusion The review indicates that urinary metabolite analysis demonstrates its applicability for the diagnosis and prognosis of disease. Urine is a remarkable and useful biofluid for routine testing and provides an excellent resource for the discovery of novel biomarkers, with an advantage over tissue biopsy samples due to the ease and less invasive nature of collection.

Abstract
Introduction Quality and quantity of jaw bones have been previously classified in literature using different methods. Imaging modalities such as computed tomography (CT), successfully determine bone density of jaws. This study aims to establish the role of cone-beam CT (CBCT) in determining the density of cortical and cancellous bones at different jaw sites. Materials and Methods Eighty-three possible implant sites in healthy patients were evaluated using NewTomGiano CBCT machine. Cross-sections were obtained and cortical and cancellous bone densities on different aspects of the virtual implant in terms of Hounsfield unit (HU) were determined using New Net Technologies software version 6.1 and were classified according to software from D1 to D4. Data were entered into SPSS software (version 19.0) and were statistically analyzed. Results The mean HU showed the highest value for cortical and cancellous in the anterior mandible (mean HU 1874.01 and 1131.73, respectively) followed by the posterior mandible (mean HU 1789.20 and 872.95, respectively) and least in posterior maxilla (mean HU 1068.26 and 830.04, respectively). Maximum D1 bone type was found in cortical bone and D2 bone type was noted in cancellous bone area. Males showed very highly significant cortical bone thickness (P < 0.001) whereas females showed more cancellous bone thickness but the results were nonsignificant. Conclusion A high degree of concordance between different regions of jaw bones with a strong correlation between the four bone types was obtained. Bone density plays a pivotal role in determining the prognosis of the implant. CBCT has proven to be beneficial in bone density analysis.

Abstract
We report the development and performance of a cold target recoil ion momentum spectrometer (COLTRIMS) setup at TIFR, which is built to study various atomic and molecular processes involving the interaction of slow, highly charged ions from an electron cyclotron resonance based ion accelerator. We give a detailed description of the experimental setup, as well as report some initial results on the electron-capture process in collisions of Ar8+ ions with helium and carbon monoxide targets. Here, we present the longitudinal momentum transfer and the sub-shell resolved Q-value spectrum in the case of 2, 4, and 6 keV/u Ar8+ beams in collision with helium. A longitudinal momentum resolution of 0.27 a.u. is achieved in the present system. We also report the state-selective scattering angle distributions for all the collision systems under investigation. We further discuss the fragmentation of the CO2+ molecular ions for different electron capture channels for the 5 keV/u Ar8+ beam. The combination of the COLTRIMS, along with the beam cleaner, the electrostatic deflectors, and the charge state analyzer, is shown to have certain advantages.

Abstract
INTRODUCTION Higher intake of fiber has been associated with lower risk of incident symptomatic osteoarthritis (OA). We examined whether levels of alkylresorcinol (AR), a marker of whole grain intake, were associated with OA in subjects in The Multicenter Osteoarthritis (MOST) Study. METHOD Knee x-rays and knee pain were assessed at baseline and through 60-months. Stored baseline fasting plasma samples were analyzed for AR homologues (C17:0, C19:0, C21:0, C23:0, C25:0) and total AR levels (AR sum). Two nested case-control studies, one for incident radiographic OA and one for incident symptomatic OA were performed with participants re-assessed at 15, 30 and 60 months. Multivariable conditional logistic regression with baseline covariates including age, sex, BMI, physical activity, quadriceps strength, race, smoking, depressive symptoms, diabetes and knee injury tested the association of log transformed AR levels with OA outcomes. RESULTS Seven hundred seventy-seven subjects were, on average, in their 60's, and most were women. For 60-month cumulative incidence, there was no significant association between quartiles of AR concentration and incident radiographic (e.g., for incident radiographic OA, highest vs lowest quartile of AR sum showed RR = 0.93 (95% CI 0.59, 1.47), and for symptomatic OA RR was 1.22 (95% CI 0.76, 1.94). In secondary analyses examining 30-month incidence, high AR levels were associated with a reduced risk of X-ray OA (RR = 0.31 (95% CI 0.15, 0.64). CONCLUSION In primary analyses, AR levels were not associated with risk of OA, but secondary analyses left open the possibility that high AR levels may protect against OA.

Abstract
Mucopolysaccharidosis VI is a genetic disorder affecting multiple organs with sundry clinical presentations. The main etiological factor reflects the disturbances in mucopolysaccharide metabolism leading to deposition of acid mucopolysaccharide in various tissues. The pathognomonic features of the disease include a large head, short neck, corneal opacity, open mouth associated with an enlarged tongue, enlargement of the skull, and long anteroposterior dimension with unerupted dentition, dentigerous cyst-like follicles, condylar defects, and gingival hyperplasia. An 18-year-old boy with Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI) is described in this article, emphasizing the oral manifestations and radiographic illustration of lesions in the jaws. It also emphasizes the essential role of cone-beam computed tomography to identify and analyze multicentric pathologies in the jaws.

Abstract
Introduction: Oral rehabilitation in maxillary anterior region has increased concerns in the dental fraternity to have detailed morphological examination in treatment planning. The nasopalatine canal (NPC) along with its contents plays an important role in determining the prognosis of implants and their associated surgeries. The present study was performed to evaluate morphometric anatomic variations of the NPC using focused small field of view on cone-beam computed tomography (CBCT). Materials and Methods: The study included 250 participants. CBCT examination was conducted using standard exposure and patient positioning protocols. Sagittal, coronal, and axial sections were reviewed to determine NPC morphology and dimensions. Results: Single, round, incisive foramen with mean mesiodistal diameter of 3.23 (±1.00) mm, and mean anteroposterior dimension of 3.03 (±0.96) mm was found. Single Stenson's foramen along with funnel shaped, slanted NPC with mean angulation of 81.97 (±42.19), and mean length of 12.67 (±2.69) mm was found. Mean mesiodistal diameter at nasal fossa of NPC was 3.27 (±1.75) mm, at mid-level was 2.23 (±1.02) mm, at palate was 3.46 (±1.12) mm. At least one additional foramen was found. Discussion: Anatomy of the NPC is highly variable. Age-wise and gender-wise correlations revealed statistically significant results for different parameters. The present study highlighted significance of NPC along with its variations. Therefore, a methodical three-dimensional presurgical assessment is mandatory before any surgical intervention in this region.

Abstract
Background: The density of cortical and cancellous bone is a key reason for implant anchorage which might be severely affected during diabetes. Aim: The aim of the study was to establish the role of cone-beam computed tomography (CBCT) using grayscale values in determining bone density in different jaw sites and in comparing the values in healthy with diabetic patients. Materials and Methods: Bone densities in 322 possible implant sites in healthy and diabetic patients were evaluated using NewTomGiano CBCT machine. Cross-sections obtained were assessed for bone densities in terms of Hounsfield Unit on different sites using New Net Technologies software version 6.1. Statistical Analysis: Data were statistically analyzed using SPSS software (version 19.0). Results: Age-wise cortical and cancellous bone densities were compared and no statistical significance was obtained. Gender-wise bone density was compared and significant results were found in males. Jaw-wise bone density was compared and was found to be significantly high in the mandible. The mean cortical bone density in control group was 1608.572 (±380.36), whereas in diabetic group was 1395.368 (±296.97), and the mean cancellous bone density in control was 906.918 (±185.40) and in diabetic was 559.868 (±128.16). Teeth wise in cortical bone significant values were found at premolar region (P = 0.046) and in cancellous bone significant values were found at canine and premolar region (P = 0.012) and highly significant values were found at molar region (P = 0.001). Conclusion: CBCT unveils a distinct pattern of cortical and cancellous bone density. A high degree of concordance between different regions of the mouth in cortical and cancellous bones was obtained in different study groups. CBCT could be used for bone density analysis.

Abstract
Background:Infections are the most common cause of morbidity and mortality in idiopathic inflammatory myositis (IIM). India is endemic for Tuberculosis (TB) with a prevalence of 2.3 cases per thousand population.Objectives:Thus, we studied the prevalence of TB in our cohort of IIM patients and compared with that in systemic lupus erythematosus (SLE).Methods:Medical records from paper charts and electronic medical records were reviewed for adults and juvenile patients with SLE (ACR criteria 1997) and IIM (Bohan and Peter criteria 1975) first presented at a tertiary care hospital in India from 1989 to 2016. Clinical variables including disease characteristics variables, the frequency, site, duration and complication of active TB as well as dose of corticosteroids and other immunosuppressive drugs were extracted retrospectively from the medical records. Descriptive statistics were used to describe the cohort and TB characteristics. Chi-square and t-test were used to evaluate association of TB with clinical diagnosis as well as medication data.Results:There were 167 (132 adults and 35 juvenile) IIM and 280 (131 adults and 149 juvenile) SLE in our cohort. Active TB occurred in 24 (14.4%) of all IIM cases (18, 13.6% adults; 6, 17.1% juvenile) as compared to 18 (6.4%) of all SLE cases (8, 6.1% adults; 10, 6.7% juvenile, p value < 0.01). Of all the TB in myositis, most often it was seen in Dermatomyositis (n=11, 45.8%) followed by Polymyositis (5, 20.8%), and occasionally in Overlap myositis (3, 12.5) and juvenile dermatomyositis (1,4.1%).Considering an annual TB rate of 211 per 100,000 of the general population, the risk of developing active TB was 62-fold higher in patients with IIM and 27-fold higher in those with lupus. Patients with IIM had higher odds of developing TB as compared with Lupus [odds ratio 2.86 (CI 1.5-5.47), p=0.007).Amongst 24 IIM patients with TB, 10 had pulmonary TB and 14 had extra-pulmonary TB. The median glucocorticoid dose at the diagnosis of TB was 0.25 (0-1.5) mg/kg/day. Half the cases of active TB occurred during inactive myositis. Seventeen patients with active TB were followed up over 27 months (8-184), with remission of TB in all cases but required prolonged courses of Anti-Tuberculous Therapy (ATT) in 25% cases with 10 ATT related adverse events in 8 patients and 5 patients with relapse of myositis due to lowering of immunosuppression.Conclusion:Patients with IIM have higher prevalence of active TB as compared with SLE patients. The risk is highest in patients with Dermatomyositis possibly related to high doses of steroids.

Abstract
Background:Scleroderma has been associated with increased risk of cardiovascular events, however,studies on this from India are sparse.We evaluated clinical and serological factors associated with subclinical atherosclerosis in Indian patients with scleroderma, in a cross-sectional design.Objectives:To compare carotid intima-medial thickness (CIMT, mean value of both carotids) as a measure of subclinical atherosclerosis (SCA) between patients with scleroderma (n=61) fulfilling 2013 ACR/EULAR criteria, and healthy controls (n=41).- To compare clinical (body mass index – BMI, waist-hip ratio – WHR, fasting lipid profile) and serological factors (microparticles, endothelial microparticles, inflammatory cytokines associated with increased cardiovascular risk) between patients with scleroderma and healthy controls.- To identify factors associated with SCA in scleroderma patients.Methods:Subclinical atherosclerosis(SCA) was defined by presence of carotid plaques, or increased CIMT >2 standard deviations compared with Indian reference standards for age and sex. Total microparticles (TMP) were measured of plasma after ultracentrifugation as per previously described protocol using microbeads of 3 μm size (TMP were of size 0.1-1 μm); of these, microparticles positive for CD31 and CD142 were endothelial microparticles (EMP). Serum cytokines (IL-1, IL-6, TNF-α, IL-17) were measured by ELISA using manufacturer instructions. Linear regression was used to identify the determinants of CIMT in scleroderma. Binomial logistic regression was used to identify factors associated with subclinical athersclerosis in scleroderma.VariablePatients with scleroderma (n=61)Healthy controls (n=41)p valueAge37.8 ± 11.9235.37 ± 6.690.2375Gender (M:F)11:506:350.6516Diabetes/Hypertension/Tobacco use1/2/00/0/0NSBody mass index (kg/m2)20.11 ± 3.8224.38 ± 4.45<0.0001Waist-hip ratio0.86 ± 0.110.89 ± 0.070.1251Total cholesterol (mg/dL)142.5 ± 30.7147.3 ± 39.50.4948Triglycerides (mg/dL)99.4 ± 37121.4 ± 460.0087HDL cholesterol (mg/dL)46.9 ± 4.946.1 ± 4.20.4029LDL cholesterol (mg/dL)93.6 ± 10.593.3 ± 7.50.8520VLDL cholesterol (mg/dL)19.9 ± 7.424.7 ± 9.70.0057Carotid intima-medial thickness (mm)0.68 ± 0.100.53 ± 0.03<0.0001Total microparticles (per±L)12913 ± 24936272 ± 1533<0.0001Endothelial microparticles (per±L)2623 ± 1032829 ± 439.5<0.0001Serum IL-1±(pg/mL)38.19 ± 13.4631.38 ± 18.290.0326IL-6 (pg/mL)176.6 ± 85.74128.9 ± 53.610.0020IL-17 (pg/mL)56.3 ± 20.4553.89 ± 20.510.5611TNF±(pg/mL)49.65 ± 26.7142.09 ± 30.410.1879Results:Despite lower BMI, triglycerides and VLDL cholesterol, CIMT was significantly higher in patients with scleroderma.

Abstract
Background:There is dearth of biomarkers in Idiopathic Inflammatory Myositis(IIM) to identify ongoing inflammation in the muscle and distinguish it from inactivity or damage.Objectives:Since myositis is autoantibody mediated and tertiary lymphoid organogenesis (TLO) reported in the diseased muscles, we investigated peripheral blood T helper subset profiling as a reflection of ongoing muscle inflammation.Methods:Twenty-six patients of IIM (ACR EULAR criteria) were compared with 15 healthy controls (HC) and 21 patients with sarcoidosis (Table 1). Peripheral blood mononuclear cells were stained with combinations of antibodies to identify Th1, Th17, Th17.1 and Treg cells after stimulation assays (BD Biosciences). Myositis Specific and Associated autoantibodies were tested by the line immunoassay (Euroimmune, Germany).Table 1.Baseline characteristics of patients with inflammatory myositisCharacteristicsDemographic details (n, % or median, IQR)Healthy Control (median, IQR)Age37±25.2526.0±32Gender(M:F)5 vs. 2112 vs. 3Diagnosis PM3 DM15 OM4 ASS4Disease course Monocyclic5 Polycyclic7 Chronic continuous1 Undefined13Clinical Profile Myositis4 (15.3%) ILD5 (19.23%) Rash3 (11.53%) Arthritis6 (23.07%) Other16 (23.69)Disease duration (years)1.3 ± 6.91Disease activity Active12 [PM(1), OM(1), ASS(4), DM(5)] Inactive14 [PM(2),OM(2),ASS(0),DM(8)]Antinuclear AntibodiesPositive Nuclear Speckled9 (34.61%) Homogenous4 (15.38%) Nucleolar1 (3.8%) Other5 (19.23%)Cytoplasmic3 (11.53%)Negative4 (15.38%)Myositis Specific AntibodiesPositive ARS2(7.6%) Mi-23(11.53%) SAE-12(7.6%) NXP22(7.6%) MDA50MAA Ku1(3.8%) dsDNA0 U1RNP0 Ro524(15.38%)Negative12(46.15%)Results:All T helper subsets were higher in myositis as compared with healthy controls (figure 1A a-d). Between various IIM subsets, polymyositis had higher Th1 and Treg cells (Figure 1B b, c) while Th17 and Th17.1 cells(c) were higher in Overlap Myositis (Figure 1B a, d) as compared with healthy controls. Patients with sarcoidosis had similar subset profiling as myositis.(Figure 5a-f)Figure 1A.

There was no difference in T cell profile between the various autoantibody subsets (Figure 6a-d).There was no difference in subsets between active and inactive disease although active disease had lower Th1/Treg, Th17/Treg and Th17.1/Treg ratios.Conclusion:T Helper cell subsets are distinct from HC but similar to sarcoidosis patients. However, they differ in various subsets of myositis, suggesting different pathogenic mechanisms are operative. Autoantibody positivity is associated with elevated Th17.1 population suggesting plasticity in TLO which needs to be explored further. However, T cell profiling cannot distinguish active from inactive disease limited predictive potential as a biomarker.Figure 2A. Comparisons between various phenotypic subsets suggest patients positive for MSA had higher Th17.1 cells (Figure 2A a(iii)) than those negative for MSA. Similarly, patients with arthritis had higher Th17.1 cells(Figure 2A b (iii)). 2B Representative dot plot of T cell subsets ratio (Th1, Th17 & Th17.1) with Treg subsets (a) Th17/Treg ratio observed higher in lower cells in active as compared with inactive disease. 2C Representative dot plot T cell subsets in Sacodosis and myositis2D Representative dot plot comparing percentage of T cell subsets in various antibody subsets of myositisAcknowledgments:The authors thank APLAR for funding Myositis antibody testing.Disclosure of Interests:None declared

Abstract
Background:Macrophage activation syndrome (MAS) is a serious complication in rheumatic disease. Fever and hyperferritinemia are common in systemic onset JIA and cytopenias are common in SLE thus recognising MAS in them is a challenge.Objectives:We compared clinical, laboratory parameters, various classification criteria for MAS, and its outcome in SLE and sJIA.Methods:Clinical and laboratory data were extracted from clinician diagnosed cases of MAS with SLE/sJIA who were admitted between 2004-2018 at a tertiary care hospital. Percentage of patients satisfying Ravelli, International consensus, HLH 2004 and criteria proposed by Parodi et al1were calculated.Results:Among 33 patients (18 females) with MAS 19 had SLE and 14 had sJIA. MAS was more likely to be the presenting manifestation of disease in SLE as compared to sJIA (p<0.05). There were no differences in the clinical features among these two diseases. EBV and CMV were identified in 2 patients each as the trigger for MAS.Patients with SLE had lower baseline TLC and platelet whereas patients with sJIA-MAS had significantly higher median CRP (p = 0.002), fall in TLC (p=0.012) and delta ESR/CRP ratio (p=0.02) and lower fibrinogen level (p=0.006). Neutrophil to lymphocyte ratio, Ferritin/CRP ratio and number of patients with Ferritin/ESR >80 were similar. Bone Marrow hemophagocytosis was seen in only in 21% of patients.Only 6/33 fulfilled HLH criteria but criteria meant for sJIA or SLE performed well for both diseases and majority of patients could be diagnosed using them. Treatment included steroids(100%), cyclosporine(30%), Tacrolimus(21%), cyclophosphamide(21%), etoposide(3%) and thalidomide(12%). Mortality was similar in both groups.Table 1.Agreement amongst MAS/HLH criteria in SLE and sJIA MASSLE-MASHLHRavelli et alConsensusParodi et alHLH4444Ravelli et al4191918Consensus4191918Parodi et al4181818sJIA-MASHLHRavelli et alConsensusParodi et alHLH2222Ravelli et al2121112Consensus2111212Parodi et al2121214Table 2.Comparison with various other cohortsMinoia et alsJIAn (%)Our studysJIA, n (%)Our Study SLE, n (%)SLE, n (%) Ai-Chun Liu et alJuvenile SLE n (%)Parodi et alNumber36214193238MAS as presenting feature (%)80 (22)4 (28)12 (63)NA24 (63)Most common manifestation (%)Fever (96)Fever (100)Fever (89)Fever (96)Fever (89)Most common triggerDisease activityDisease activityDisease activityDisease activityDisease activityBM done251 (72.3)8 (57)12 (63)32 (96)38 (100)BM hemophagocytosis150 (60.7)2 (25)5 (41)32 (100)20 (52)Mortality28 (8)2 (14)2 (10.5)4 (12.5)4 (11.4)Patients meeting JIA criteria %NA-100NA100Patients meeting HLH criteria %NA1419NA66Conclusion:MAS is more likely to be presenting manifestation in SLE compared to sJIA.

Abstract
Hybrid ameloblastoma has a variable clinical, radiological, and histopathological presentation. They contain two or more different histologic types and their biologic comportment is still arguable. We herein present a case of a hybrid variant of desmoplastic ameloblastoma which is the first of its kind to have ever been reported due to its unusual location in the maxillary anterior region, along with systematic review of clinicopathologic features of reported cases immunohistochemical markers may act as an adjunct in the accurate diagnosis of these lesions.

Abstract
OBJECTIVE Thiazide diuretic use is associated with higher bone mineral density (BMD) and possibly lower serum magnesium levels than loop diuretic use, and both high BMD and low serum magnesium have been linked to high prevalent knee osteoarthritis. This study aimed to compare the risk of a clinically relevant endpoint, knee replacement (KR) surgery, among initiators of thiazide and loop diuretics. DESIGN Among patients aged ≥50 years with a diagnosis of knee osteoarthritis in The Health Improvement Network (THIN) in United Kingdom, we conducted a propensity score-matched cohort study to examine the relation of thiazide diuretic initiation vs loop diuretic initiation to the risk of KR over 5 years. RESULTS Among thiazide and loop diuretic initiators (n = 3,488 for each group; mean age: 73 years; female ratio: 59%), 359 (28.6/1,000 person-years) and 283 (24.1/1,000 person-years) KRs occurred during the follow-up period, respectively. The hazard ratio (HR) of KR for thiazide diuretic initiation vs loop diuretic initiation was 1.26 (95% confidence interval [CI]: 1.08-1.47). The adherence-adjusted HR of KR for continuous use of thiazide diuretics was 1.44 (95% CI: 1.21-1.72). CONCLUSIONS In this population-based cohort of patients with knee osteoarthritis, thiazide diuretic use was associated with a higher risk of KR than loop diuretic use. This association may potentially be due to thiazide diuretics' effect on BMD and serum magnesium.

Abstract
Eagle's syndrome, also known as an elongated styloid process, is a condition that may be the source of craniofacial and cervical pain. It is infrequently reported but is probably more common than generally considered. The symptoms related to Eagle's syndrome can be confused with those attributed to a wide variety of facial neuralgia and or oral, dental, and temporomandibular joint diseases. In this paper, there are two cases, which reported to the Department of Oral Medicine, Diagnosis, and Maxillofacial Radiology, with a chief complaint of radiating pain in the preauricular region of the face. After radiographic investigation, these cases are considered as a case of Eagle's syndrome because of increase in the size of the styloid process.

Abstract
OBJECTIVE Providing effective dietary counselling so that pregnancy weight gain remains within the 2009 Institute of Medicine (IOM) guidelines requires accurate maternal energy intake measures. Current practice is based on self-reported intake that has been demonstrated unreliable. This study applies an objective calculation of energy intake from a validated mathematical model to identify characteristics of individuals more likely to misreport during pregnancy. METHODS A validated maternal energy balance equation was used to calculate energy intake from gestational weight gain in 1,368 subjects. The difference between self-reported and model-predicted energy intake was tested for demographics, economic status, education level and maternal health status. RESULTS A weight gain of 15.2 kg resulted in model-predicted intake during pregnancy of 2,882.97 ± 135.71 kcal day-1, which differed from self-reported intake of 2,180.5 ± 856.0 kcal day-1. The achieved weight gain exceeded the IOM guidelines; however, the model predicted weight gain from self-reported energy intake was below IOM guidelines. Higher income (p = 0.004), education (p = 0.003), birth weight (p = 0.017), gestational diabetes (p = 0.008) and pre-existing diabetes (p < 0.001) were associated with under-reported energy intake. More children living at home (p = 0.001) were associated with more accurate self-reported intake. CONCLUSIONS When assessing self-reported energy intake in pregnancy studies, birth weight, gestational diabetes status, pre-existing diabetes, higher income and education predict higher under-reporting. Clinicians providing dietary treatment recommendations during pregnancy should be aware that individuals with pre-existing diabetes and gestational diabetes mellitus are more likely to misreport their intake. Additionally, the systems model approach can be applied early in intervention to objectively monitor dietary compliance to treatment recommendations.

Abstract
Cell death appears to be a basic biological phenomenon which is maintained by the human body. The term apoptosis, also known as programmed cell death, is characterized by several unique morphological and biochemical features. Apoptosis and its different forms are essential for tissue homeostasis. Alteration in molecular mechanisms involved in apoptotic signaling contributes to a vast range of oral diseases. An understanding of the regulation of apoptosis has led to the development of many therapeutic approaches and better management of oral diseases. The review updates us the correlation between apoptosis in normal oral tissues and oral diseases.

Abstract
OBJECTIVE The present comparative study was aimed to determine the effectiveness of Th US and TENS in the management of myofascial pain in TMD patients. MATERIALS AND METHODS The present randomized comparative study was on 90 patients who were further assigned in three different groups each having 30 patients; Group I was healthy control patients, Group II was receiving Th US therapy, and Group III was receiving TENS therapy. All the 90 patients were further evaluated for maximum inter incisor subjective evaluation regarding muscle pain, impediment to daily life, massage impression on visual analog scale (VAS) scale, and intensity and duration used in Th US massage. RESULTS The masseter muscle thickness in control group was 12.00 (standard deviation [SD] ±1.1) mm when compared with TMD patient of 13.00 (SD ± 1.1) mm before treatment. Statistical significant findings on VAS score of muscle pain, impediment to daily life, and massage impression were observed in Th US. After treatment, the anechoic areas disappeared or were reduced in Th US group by 95.6% and in TENS by 74.4%. CONCLUSION Th US appeared to be subjectively better which was related to VAS score of massage impression, muscle pain, and impediment to daily life after treatment as well as sonographically related to existence of anechoic areas.

Abstract
Context: Admantinoma is second most common benign odontogenic tumor which clinically appears as an aggressive odontogenic tumor, often asymptomatic and slow growing, associated with symptoms such as swelling, dental malocclusion, pain, and paresthesia of the affected area. The radiographic appearance may vary from unilocular to multilocular radiolucencies, imparting a characteristic honey comb, soap bubble appearance or may resemble a caricature of spider. Case Report: This report highlights the importance of conventional and advanced imaging in the diagnosis of large and invasive lesions. Patient reported with complaint of swelling in jaw, which progressively increased; and was found to be bony hard, both intra- and extraorally. Radiographs revealed large multilocular radiolucency on left body and ramus of mandible with soap bubble pattern and knife edged root resorption. Computed tomographic examination evaluated the extent of the lesion, internal structure, and relation to adjacent structures; further a reconstructed image was obtained to evaluate extent of destruction in three dimensions. Conclusion: Computed tomography has an important role in the diagnosis and treatment planning is imperative as it is superior in revealing the cortical destruction and extension into the neighboring soft tissues than conventional radiography.

Abstract
We report the development and performance studies of a newly built recoil ion momentum spectrometer for the study of atomic and molecular fragmentation dynamics in gas phase upon the impact of charged particles and photons. The present design is a two-stage Wiley-McLaren type spectrometer which satisfies both time and velocity focusing conditions and is capable of measuring singly charged ionic fragments up-to 13 eV in all directions. An electrostatic lens has been introduced in order to achieve velocity imaging. Effects of the lens on time-of-flight as well as on the position have been investigated in detail, both, by simulation and in experiment. We have used 120 keV proton beam on molecular nitrogen gas target. Complete momentum distributions and kinetic energy release distributions have been derived from the measured position and time-of-flight spectra. Along with this, the kinetic energy release spectra of fragmentation of doubly ionized nitrogen molecule upon various projectile impacts are presented.

Abstract
A reaction microscope (ReMi) has been combined with a magneto-optical trap (MOT) for the kinematically complete investigation of atomic break-up processes. With the novel MOTReMi apparatus, the momentum vectors of the fragments of laser-cooled and state-prepared lithium atoms are measured in coincidence and over the full solid angle. The first successful implementation of a MOTReMi could be realized due to an optimized design of the present setup, a nonstandard operation of the MOT, and by employing a switching cycle with alternating measuring and trapping periods. The very low target temperature in the MOT (∼2 mK) allows for an excellent momentum resolution. Optical preparation of the target atoms in the excited Li 2(2)P3/2 state was demonstrated providing an atomic polarization of close to 100%. While first experimental results were reported earlier, in this work, we focus on the technical description of the setup and its performance in commissioning experiments involving target ionization in 266 nm laser pulses and in collisions with projectile ions.

Abstract
CONTEXT The calcifying odontogenic cyst (COC), also referred to as calcifying ghost cell odontogenic cyst (CGCOC) is a heterogeneous lesion existing either as cystic or solid variant. Due to the fact that all CGCOC lesions are not cystic, and the biological behavior is often not consistent with a cyst, there has always been a controversy as to whether COC is a cyst or a tumor. The dentinogenic ghost-cell tumor (DGCT), a solid variant of the COC, is an uncommon odontogenic neoplasm occurring predominantly in later life. Case report is followed by a concise review and disambiguation of controversial terminologies regarding nomenclature of COC. CASE REPORT We report a case of 33-year-old female patient who presented with an insidious, steadily increasing swelling on the left side of her face since 8 months. Patient reported slight difficulty in eating because of reduced intraoral space and an obvious concern with facial disfigurement. There was no contributory dental or medical history. Intraorally, a hard, well defined, bicortical swelling was noted in left maxillary region with slight mobility of the associated teeth and normal appearing overlying mucosa. A provisional diagnosis of adenomatoid odontogenic tumor was made, and orthopantomogram, paranasal sinus radiograph and computed tomograpy scan of the face were acquired. A radiographic diagnosis of COC was made, which was subsequently confirmed on histopathology postenucleation of the tumor mass. COC has been seen to be of extensive diversity in its clinical and histopathological features as well as in its biological behavior. CONCLUSION The present case of 33-year-old female was diagnosed as DGCT, a tumorous form of COC, due to its characteristic histological features; numerous ghost cells and dentinoid material.

Abstract
UNLABELLED Association between warfarin use and fracture risk is unclear. We examined the association between long-term warfarin use and fracture risk at the hip, spine, and wrist in elders. No significant association was found between long-term warfarin use and fracture risk, despite biological plausibility. INTRODUCTION Prior studies examining the association of warfarin use and osteoporotic fractures have been conflicting, potentially related to methodological limitations. Thus, we examined the association of long-term warfarin use with risk of hip, spine, and wrist fractures among older adults with atrial fibrillation, attempting to address prior methodologic challenges. METHODS We included men and women ≥ 65 years of age with incident atrial fibrillation and without prior history of fractures from The Health Improvement Network followed between 2000 and 2010. Long-term warfarin use was defined in two ways: (1) warfarin use ≥ 1 year; (2) warfarin use ≥ 3 years. Propensity-score matched cohorts of warfarin users and nonusers were created to evaluate the association between long-term warfarin use and risk of hip, spine, and wrist fractures separately as well as combined, using Cox-proportional hazards regression models. RESULTS Among >20,000 participants with incident atrial fibrillation, the hazard ratios (HR) for hip fracture with warfarin use ≥ 1 and ≥ 3 years, respectively, were 1.08 (95%CI 0.87, 1.35) and 1.13 (95% CI 0.84, 1.50). Similarly, no significant associations were observed between long-term warfarin use and risk of spine or wrist fracture. When risk of any fracture was assessed with warfarin use, no association was found [HR for warfarin use ≥ 1 year 0.92 (95%CI 0.77, 1.10); HR for warfarin use ≥ 3 years 1.12 (95%CI 0.88, 1.43)]. CONCLUSIONS Long-term warfarin use among elders with atrial fibrillation was not associated with increased risk of osteoporotic fractures and therefore does not appear to necessitate additional surveillance or prophylaxis.
