Abstract
The developmental anomaly of the middle cerebral artery (MCA) is a rare occurrence. Rete MCA, also known as "unfused," "twig-like," and aplastic MCA, is an even rarer anomaly. These immature rete vessels are prone to flow-related aneurysms which rupture themselves presenting with intraparenchymal hematoma. We here with present a case of rete MCA with a ruptured aneurysm and discuss its pathophysiology and management.

Abstract
BACKGROUND Despite recent breakthroughs in caries preventive measures, one of the biggest issues clinicians confront is preventing demineralization while undergoing orthodontic therapy. The buildup of plaques around orthodontic brackets over time causes white spot lesions (WSLs). The goal of the present research was to assess the prevalence of WSLs in patients undergoing orthodontic treatment before starting therapy and at six and 12 months into therapy, adopting the visual examination approach. MATERIALS AND METHODS We looked for WSLs on tooth surfaces gingival to an archwire because this is the area most likely to experience enamel demineralization during orthodontic treatment. The visual assessment was conducted using the following scale at baseline, six months, and 12 months for orthodontic patients: score 0: no demineralization or noticeable white patches on the surface; score 1: mild demineralization with a visible white spot but no surface disruption; score 2: moderate demineralization with a noticeable WSL that has a roughened surface but does not need repair; and score 3: severe demineralization with a noticeable WSL that needs repair. Fisher's exact test was used after a chi-square analysis to determine whether there were any differences between all three categories (six months, 12 months, and control). RESULTS The frequency of WSL in patients at 12 months of orthodontic treatment was 46.57%, while it was 11.86% in patients who just started orthodontic treatment. The difference was statistically significant (p = 0.01), showing that the frequency was greater in patients at 12 months of orthodontic treatment as compared to patients who had just started undergoing orthodontic treatment. The frequency of WSL in patients at six months of orthodontic treatment was 37.34%, while it was 11.86% in patients who just started orthodontic treatment. The difference was statistically significant (p = 0.03), showing that the frequency was greater in patients at six months of orthodontic treatment as compared to patients who had just started undergoing orthodontic treatment. The frequency of WSL in patients at six months of orthodontic treatment was 37.34%, while it was 46.57% in patients at 12 months of orthodontic treatment. The frequency was greater in patients at 12 months of orthodontic treatment as compared to patients at six months of orthodontic treatment; however, the difference was non-significant statistically (p = 0.76). CONCLUSION This clinical investigation revealed that the number of WSLs increased significantly during the first six months of treatment and then increased gradually until the final 12 months. During the first few months of treatment, doctors should assess the patients' dental hygiene habits and, if necessary, take further precautions to prevent demineralization.

Abstract
OBJECTIVES To determine the association of eNOS (T786C and 27bp VNTR) gene polymorphism with the risk of type II diabetes mellitus and diabetic nephropathy in North India. METHODS The prospective case control study was conducted over a period of 18 months. A total of 100 patients of Type 2 Diabetes Mellitus (A1: 50 cases without Diabetic nephropathy-DN and 50 cases with DN) aged 18-75 years and 50 healthy adults as control (Group B) were included. The endothelial nitric oxide gene variant (T786C and 27bp VNTR) genotypes and alleles were studied. Odds ratio with 95% CI was calculated for genotype and alleles for the occurrence of diabetes and DN. p value of less than 0.05 was considered as significant. RESULTS With Bb as reference(27bp VNTR), the odds ratio for Ab in the three groups (A1,A2,B) was 2.243, 1.545 and 0.746 respectively; and for Aa was 3.043, 3.058 and 1.878 respectively; with TT as reference (T786C), it was 1.573, 1.55 and 1.055 respectively for TC; and for CC it was 2.121, 2.063 and 2.348 respectively. The OR was comparable among the study groups and control for all genotypes and alleles (p>0.05). CONCLUSION In conclusion, there was a trend towards higher predilection of DN with aa genotype and a allele in 27 VNTR, CC genotype and C allele of -786T>C polymorphism however it was not found to be statistically significant. Future large sample studies are required to account for the ethnic variation for a clearer association of the genes and their associated risk with Diabetes and its complications.

Abstract
BACKGROUND: Extrapulmonary TB (EPTB) comprises approximately 15-20% of TB cases worldwide, and its diagnosis is difficult. The sensitivity of Xpert® MTB/RIF (Xpert) in the diagnosis of EPTB is low on account of its paucibacillary nature. Xpert® MTB/RIF Ultra (Ultra) was developed to improve sensitivity.OBJECTIVE: To compare the sensitivity of Ultra test with that of Xpert against MGIT™ (Mycobacteria Growth Indicator Tube) culture and a composite reference standard (CRS).METHODS: We recruited consecutive treatment-naïve patients with suspected EPTB. Demographic information, clinical and relevant laboratory data were collected.RESULTS: From January 2019 to November 2019, 210 patients provided 250 samples. Against MGIT culture, the sensitivity of Ultra was significantly higher than Xpert (72% vs. 51.1%; P = 0.04), the specificity was lower (87.8% vs. 95.1%). Against the CRS also, the sensitivity of Ultra was significantly higher than Xpert (45.4% vs. 25.2%; P = 0.002); however, the specificities were similar (98.2% vs. 99.1%). The trend towards higher sensitivity of Ultra compared to Xpert was seen in most of the individual samples. The sensitivities against MGIT and CRS were as follows: lymph node (68.1% vs. 31.8%; P = 0.01) and (59.5% vs. 23.8%; P = 0.001), pleural biopsy (80.0% on both; P = NS) and (53.8% vs. 46.2%; P = NS) and pleural fluid (66.7% vs. 50%; P = NS) and (22.5% vs. 9.6%; P = NS), respectively.CONCLUSIONS: Xpert Ultra showed a significantly higher sensitivity in diagnosing EPTB than Xpert.

Abstract
Aim: The aim of the study was to compare the efficacy of transdermal diclofenac patch with ketoprofen patch as postoperative analgesia after extraction of first premolars bilaterally in both arches for orthodontic purpose. Materials and Methods: A split-mouth technique was used in 52 patients with the age group of 15–25 years for extracting maxillary and mandibular first premolars bilaterally for orthodontic reason. A single ketoprofen patch was used after the extraction of premolars from first and fourth quadrant, whereas for the extraction of second and third quadrant premolars, diclofenac patch was used. All the extractions were performed under local anesthesia. The data were compiled and statistically analyzed using the student's t-test. Results: Mean visual analog scale score for diclofenac and ketoprofen patch was 2.05 (0.75) and 1.09 (0.3), respectively. Thirteen patients required additional medication (25%) and 1 (1.9%) patient with diclofenac and ketoprofen patch, respectively. No major complication or adverse effects were observed in any of the groups. Conclusion: Both diclofenac and ketoprofen transdermal patches are helpful in relieving pain after orthodontic extraction. Patients with diclofenac patch required more additional analgesia within 24 h compared to that with ketoprofen patch. None of the drugs showed any significant adverse effects and were well tolerated by the patients.

Abstract
Aim: This study is aimed to compare and evaluate the changes in the microflora in immediate and delayed placed implants. Materials and Methods: In this study, the implant site sample was taken and assessed during different phases of treatment for delayed and immediate implants. They were looked for Streptococcus, Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Porphyromonas gingivalis, and Fusobacterium nucleatum. Results: The results showed that Streptococci were found in a higher number in all the phases of the treatment. The presence of pathogenic organisms such as P. gingivalis and Fusobacterium, in considerable amounts, was seen in both the groups. Conclusion: Thus, we conclude that implant mode of placement, delayed or immediate placement does not alter the flora of the oral cavity. Organisms present remains the same in all the phase of the treatment. To prevent the disease, one must continuously monitor the implant, with the increasing age changes, the microflora is continually changing in the oral cavity. The periodontal health should be assessed before the placement of the implant, followed by follow-ups after a set period for a better prognosis.

Abstract
Nosocomial infections are a major concern to both clinicians and health care seekers. Investigations have suggested that laptops & mobile phones may contribute to cross-contamination and can serve as vehicles for infection transmission. Therefore, it is of interest to document the data on hidden reservoirs such as mobile phones and laptops of pathogens in dental settings at the Hazaribag College of dental sciences and Hospital, Jharkhand. The samples were collected from 25 laptops and 25 mobile phones from dentists working in a dental college in Hazaribag city. The samples were collected aseptically using sterile cotton swabs dipped in sterile saline by rotating the swabs on the keyboard surfaces of laptops and mobile phones, inoculated into Brain Heart Infusion broth, vortexed for 1 minute in Fischer Vortex Genie 2 on highest setting & streaked immediately on 5% sheep blood agar plates and were incubated at 37°C for 24 hours aerobically. The isolates were identified based on the colony morphology, colony characteristics and biochemical reactions. The bacterial species isolated were Staphylococcus aureus, Coagulase negative Staphylococcus, Bacillus species, Enterococci, Micrococci, and Pseudomonas etc. Predominant species isolated was Staphylococcus aureus and least was Micrococci. Higher percentage of organisms was found at the Department of Periodontics, Endodontics and least was found in Department of Public Health Dentistry. The percentage and type of organism isolated from keyboards of laptops and mobile phones were similar. Thus, laptops and mobile phones act as vehicles for transfer of potential pathogens associated with dental hospitals. Disinfecting the hands prior to examination of patients and disinfection of laptops and mobiles with alcohol wipes should be done to prevent nosocomial infections.

Abstract
Aesthetic restorative procedures have gained immense popularity in the recent years. Midline diastemas have been commonly reported by a majority of patients due to poor aesthetic appeal. Various treatment modalities are available and cases have to be managed differently depending on the aetiological factors. Also, the selection of an appropriate restorative option is imperative to providing a pleasing smile. Conservative treatments that provide a solution to aesthetic problems and fulfil the patient’s expectations should always be the first therapeutic option. Ceramic veneers are capable of providing an accurate replica of the natural teeth along with good colour stability and periodontal biocompatibility. Soft tissues play a vital role in creating a harmonious and aesthetic result between the restorations, hard tissues and surrounding gingiva. Therefore, periodontal treatments such as crown lengthening and frenectomy are essential for creating an ideal soft tissue form corresponding to the tooth proportions. Management of large anterior interdental spaces requires a comprehensive treatment planning and often, a multidisciplinary approach is essential from a team of restorative dentists and periodontists to focus on the aetiological factors, patient needs, aesthetics and achieve stable long-term clinical results. The present case report discussed the satisfactory management of a wide anterior maxillary midline diastema in a 30-year-old female using a conservative perio-restorative approach with ceramic veneers after frenectomy and aesthetic crown lengthening procedure without any orthodontic intervention. The success of the present case was determined by a proper diagnosis of the underlying aetiology, treatment planning, use of ceramic veneers and total-etch adhesive technique.

Abstract
The northeastern Arabian Sea (NEAS) experiences convective mixing during winter, but this mixing does not reach up to the silicicline, resulting in the limited supply of silicate (Si) compared to nitrate (N) and phosphate (P) to the mixed layer (ML) and formation of non-diatom blooms. The poleward advection of waters of low surface salinity by the West India Coastal Current (WICC) to the NEAS weakens the vertical mixing and reduces the Si input to the mixed layer, resulting in occurrence of Noctiluca scintillans blooms. The saturation of dissolved oxygen in the NEAS varied between 88 and 98%, suggesting N. scintillans blooms occur in oxic conditions. Enhanced cell abundance of N. scintillans was observed in the bloom region in the upper 10 m. Phytoplankton pigments data revealed higher contribution of Chlorophytes, Prasinophytes, Prymnesiophytes and Prochlorophytes in the bloom than non-bloom region. The isotopic composition of nitrogen and carbon of particulate organic matter indicated that natural and in situ processes contributed to both nutrients and organic carbon pool in the NEAS in supporting the massive occurrence of N. scintillans blooms than hitherto hypothesized to anthropogenic sources. This study further suggests that the effect of anthropogenic pollutants released into the NEAS from the mega-cities is limited to the neighbourhood of these cities and does not affect the open ocean.

Abstract
SETTING Antiretroviral treatment (ART) Centre in Tumkur district of Karnataka State, India. There is no published information about pre-ART loss to follow-up from India. OBJECTIVE To assess the proportion lost to follow-up (defined as not visiting the ART Centre within 1 year of registration) and associated socio-demographic and immunological variables. DESIGN Retrospective cohort study involving a review of medical records of adult HIV-infected persons (aged ⩾15 years) registered in pre-ART care during January 2010-June 2012. RESULTS Of 3238 patients registered, 2519 (78%) were eligible for ART, while 719 (22%) were not. Four of the latter were transferred out; the remaining 715 individuals were enrolled in pre-ART care, of whom 290 (41%) were lost to follow-up. Factors associated with loss to follow-up on multivariate analysis included age group ⩾45 years, low educational level, not being married, World Health Organization Stage III or IV and rural residence. CONCLUSION About four in 10 individuals in pre-ART care were lost to follow-up within 1 year of registration. This needs urgent attention. Routine cohort analysis in the national programme should include those in pre-ART care to enable improved review, monitoring and supervision. Further qualitative research to ascertain reasons for loss to follow-up is required to design future interventions.

Abstract
Cycloplatination of XMeC6H4CCC-(Rf) (N-4-OCH3C6H4) [X = S, Se and Rf = perfluoroalkyl groups] with PtCl2 gave a monomeric octahedral Pt(iv) complex. Emission and reactivity studies of the Pt(iv) complexes are discussed.

Abstract
Lay et al. (Research Articles, 20 May 2005, p. 1127) estimated a 600-km length for the tsunami source region. Adding tide-gauge data from Paradip, the northernmost of the Indian east-coast stations and therefore the most critical constraint on the northern extent of the source, we estimate that its length was greater by approximately 30%.
