Evaluation of different taste sensations along with body mass index (BMI) in geriatric patients with and without complete dentures.

BACKGROUND: The purpose of this study was to investigate the effect of acrylic full removable dentures on the perception of four primary tastes (sweet, sour, salty, and bitter), as well as to determine if there is a correlation between changes in body mass index (BMI) and taste perception. MATERIALS AND METHODS: A total of 60 patients who wore acrylic removable dentures and 60 controls were included in the study as a convenient sample. Sixteen solutions for basic tastes were prepared, and the patients were asked to identify the taste of each solution from the lowest concentration. Anthropometric measures, such as height and weight, were measured and recorded in an MS-Excel sheet. The data were analyzed using SPSS version 23. RESULTS: The results showed that patients with complete removable dentures had lower taste scores for sourness (P < 0.001) and sweetness (P < 0.001) compared to the control group. However, there was no significant difference in salt taste scores (P = 0.218) and bitterness (P = 0.002) between the two groups. Additionally, the study found a correlation between lower BMI values and higher taste scores among denture-wearing patients, indicating an inverse relationship between total taste scores and BMI. CONCLUSIONS: The study suggests that geriatric patients with complete dentures have reduced taste sensations compared to those without dentures which can have a negative impact on their nutritional status. Therefore, it is crucial to provide adequate nutritional support and dietary counseling for geriatric patients based on health policy to maintain their overall health and well-being.

Unusual case presentation associated with impacted mandibular molars: Clinicopathological correlation and immunohistochemical analysis.

ABSTRACT: Ewing's sarcoma of bone is a rare malignant round cell tumor of the head and neck. The jaw, particularly the mandible, accounts for 3% of occurrences in the head and neck area. These tumors have been reported more frequently in men than in women, and they are usually between 5- and 20-year-old. It is difficult for clinicians and pathologists to make a diagnosis based solely on clinical and microscopic findings. Immunohistochemistry presents a plausible tool that can help the pathologist to arrive at a confirmatory diagnosis. This jaw tumor has the best prognosis when detected and treated early in the disease course, so the importance of timely, and accurate diagnosis cannot be overemphasized. The highlighting feature of this case report of an 18-year-old male that was primary detected by immunohistochemically as Ewing's sarcoma and is localized to the impacted left mandibular molars.

Delayed Eruption of Tooth Due to Peripheral Giant-Cell Granuloma: An Unusual Presentation and Treatment in 15-Year-Old Child Patient.

Peripheral giant-cell granulomas (PGCGs) are reddish color lesions of the gingiva which are frequently diagnosed on a routine basis by many dentists in the regular dental practice. Most of the lesions of PGCG are slow-growing, nonaggressive with asymptomatic, and tend to recur. Here, we exhibit a case of PGCG of the upper jaw in a 15-year-old girl child. She presented with a chief complaint of a lump on her upper anterior tooth region for 2-3 months. A well-defined painless, sessile exophytic growth, measuring about 1 cm × 0.5 cm in dimension with pinkish red in color with a firm consistency, was noted. Moreover, no secondary changes were seen. On the radiograph also, no changes in the bone/tooth were observed. The provisional diagnosis was identified as benign lesions such as pyogenic granuloma, peripheral ossifying fibroma, and PGCG and was made based on the clinical history and radiographic findings, and the confirmative diagnosis was given after histopathological examination. To improve the esthetic and function of teeth as well as psychological problems in the young patient, we tend to manage the case more simply by conservative surgical procedure at the earliest to prevent a recurrence.

Assessing physical and chemical properties of saliva among tuberculosis patients on anti-tuberculosis treatment - An observational study.

Background: Tuberculosis (TB) is one of the major systemic conditions which is a preventable and curable infection but remains a significant cause of death. The WHO, in its global plan to stop TB reports, that poor treatment has resulted in the evolution of Mycobacterium tuberculosis strains that do not respond to treatment with the standard first-line combination of anti- tuberculosis medicines, resulting in the emergence of multidrug-resistant tuberculosis in almost every country of the world.The present study was aimed to assess the physical and chemical property of stimulated and unstimulated saliva and identify if any association exist with alterations in taste perception in patients with antituberculosis medications. Methods: A total of 30 patients on anti-tuberculosis drugs were considered as cases and 30 healthy volunteers were considered as controls and included in the study. All study subjects were assessed for their physical property like flow rate, viscosity, pH and chemical property like sodium, potassium, calcium, phosphorous of stimulated and unstimulated saliva. All the subjects on Anti-tuberculosis drugs were assessed for change in taste perceptions using the standard questionnaire. Results: There is a significant decrease in the flow rate (0.34 ±â€¯0.06) and pH (5.89 ±â€¯0.37) of unstimulated saliva of patients and the flow rate (0.38 ±â€¯0.07) and viscosity (1.34 ±â€¯0.28) of stimulated saliva among the case group compare to the control group. All the electrolytes' concentrations such as sodium, potassium, calcium, and phosphorous values were significantly altered in stimulated and unstimulated saliva of the case group compared to the control group in which p-value < 0.05 was considered. Conclusion: There are significant changes in physical and chemical properties of both stimulated and unstimulated saliva which has an effect on taste perception inpatient with anti-tuberculosis medications. Hence, salivary flow rate, pH, viscosity, and salivary electrolytes of tuberculosis patients should be considered as important parameters in guiding the diet, so that there will be an improvement in their taste perception and medication protocol, thus maintaining their nutritional status which leads to improving their health.

Dental caries: Impact of tobacco product among tobacco chewers and tobacco smokers.

Objective: Tobacco is the most significant social burden and the leading cause of death. Tobacco is derived from "Nicotiana tabacum" which has nicotine as the main component. There are various disadvantages from tobacco on health which are reported in the medical literature. But the risk of caries among these tobacco users, such as chewers and smokers, is still debatable. Hence, the present study aims to determine the prevalence of dental caries among tobacco chewers and smokers. Materials and methods: In this study, 389 individuals were included. Out of 389 individuals, 304 were men and 85 were women aged between 18 and 60 years. They were classified into two groups. Group A had 207 individuals with habitual tobacco chewing, and Group B had 182 individuals with habitual tobacco smoking and provided a 6 months history. The DMFT index (Decayed, Missing, and filled teeth index-WHO modification 1997) was used to assess caries. Results: The study revealed a higher prevalence of dental caries among tobacco chewers compared to tobacco smokers. The DMFT scores were higher among gutka chewers compared to other types of tobacco use. The lower posterior tooth region showed higher dental caries in tobacco chewers compared to smokers. Conclusion: The higher presence of caries in the tobacco chewing group is due to the presence of sweeteners, which act as cariogenic agents. Similarly, smokers have a thiocyanate component that acts as an anticariogenic agent; therefore, the prevalence of caries was lower in tobacco smokers.

Unusual case presentation of an aneurysmal bone cyst of maxilla in geriatric patient: A diagnostic challenge.

An aneurysmal bone cyst (ABC) is a non-neoplastic, rapidly expanding pathologic bone lesion that mostly affects the mandible and is most commonly found in the first to third decade of life. The most of the ABC cases are locally aggressive osteolytic lesion with a high recurrence rate. As a result, we present a swelling with pus discharge at the maxillary alveolus in a 68-year-old female who was diagnosed with ABC after a computed tomography scan and histological analysis. The conservative surgical excision was performed without considerable bleeding, and no recurrence was observed even after a five-year follow-up period.

JUSTIFICATION: In view of new developments in vaccinology and the availability of new vaccines, there is a need to revise/review the existing immunization recommendations. PROCESS: Advisory Committee on Vaccines and Immunization Practices (ACVIP) of Indian Academy of Pediatrics (IAP) had a physical meeting in March, 2020 followed by online meetings (September-October, 2020), to discuss the updates and new recommendations. Opinion of each member was sought on the various recommendations and updates, following which an evidence-based consensus was reached. OBJECTIVES: To review and revise the IAP recommendations for 2020-21 and issue recommendations on existing and new vaccines. RECOMMENDATIONS: The major changes include recommendation of a booster dose of injectable polio vaccine (IPV) at 4-6 years for children who have received the initial IPV doses as per the ACVIP/IAP schedule, re-emphasis on the importance of IPV in the primary immunization schedule, preferred timing of second dose of varicella vaccine at 3-6 months after the first dose, and uniform dosing recommendation of 0.5 mL (15 µg HA) for inactivated influenza vaccines.

Immunization During the COVID-19 Pandemic: Recommendations From Indian Academy of Pediatrics Advisory Committee on Vaccines and Immunization Practices.

During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, immunization practices of all age groups, especially routine childhood vaccines, have been interrupted. Immunization is considered an essential health activity, which needs to be resumed as early as possible. This pandemic has created several unique issues related to routine immunization of individual children at clinics, which needs to be addressed. In this communication, the Advisory Committee on Vaccines and Immunization Practices (ACVIP) of Indian Academy of Pediatrics addresses the common questions and issues related to SARS-CoV-2 and routine immunization services. This also includes the recommendations for routine immunization of SARS-CoV-2 suspect and positive children, and for the logistics to be followed for immunization services.

Prevalence of Shukra vega dharana in an Indian population: A cross sectional survey protocol.

BACKGROUND: Despite being an important aspect of health and quality of life, individuals tend to suppress natural sexual urge ('Shukra vega') due to a variety of factors. Unless managed appropriately through self-regulatory mechanisms, suppressed sexual urge ('Shukra vega dharana', SVD) not only causes psychological suffering but may also put other basic needs at risk. Adult, married, males who are either living away from their spouse for long durations or separated or divorced are at a considerably higher risk of developing SVD as compared to others. Considering the recent rise of sexual diseases and sexual violence, it is critical to understand the extent and epidemiology of SVD in this sub-population of India. OBJECTIVE: The study was attempted to understand the extent and epidemiology of SVD in this sub-population of India. MATERIALS AND METHODS: To determine the prevalence of SVD in adult married, male individuals located in Nashik, Ahmadnagar and Thane cities of India who are either living away from their spouse or separated or divorced, a crosssectional, anonymous survey will be conducted among a sample of male individuals meeting eligibility criteria. A multi-stage sampling approach will be used to identify cities/organizations (where the study will be conducted) and participants for the study. Post informed consent, eligible individuals will respond to a survey questionnaire. Responses will be populated in a spreadsheet, analyzed and reported. Understanding extent and epidemiology of SVD in an Indian sub-population will not only facilitate design of future research studies but will also inform health, social and educational policy associated with sex education (training individuals in the appropriate management of sexual urge).

Indian Academy of Pediatrics (IAP) Advisory Committee on Vaccines and Immunization Practices (ACVIP) Recommended Immunization Schedule (2018-19) and Update on Immunization for Children Aged 0 Through 18 Years.

JUSTIFICATION: There is a need to revise/review recommendations regarding existing vaccines in view of current developments in vaccinology. PROCESS: Advisory Committee on Vaccines and Immunization Practices (ACVIP) of Indian Academy of Pediatrics (IAP) reviewed the new evidence, had two meetings, and representatives of few vaccine manufacturers also presented their data. The recommendations were finalized unanimously. OBJECTIVES: To revise and review the IAP recommendations for 2018-19 and issue recommendations on existing and certain new vaccines. RECOMMENDATIONS: The major changes in the IAP 2018-19 Immunization Timetable include administration of hepatitis B vaccine within 24 hours of age, acceptance of four doses of hepatitis B vaccine if a combination pentavalent or hexavalent vaccine is used, administration of DTwP or DTaP in the primary series, and complete replacement of oral polio vaccine (OPV) by injectable polio vaccine (IPV) as early as possible. In case IPV is not available or feasible, the child should be offered three doses of bivalent OPV. In such cases, the child should be advised to receive two fractional doses of IPV at a Government facility at 6 and 14 weeks or at least one dose of intramuscular IPV, either standalone or as a combination, at 14 weeks. The first dose of monovalent Rotavirus vaccine (RV1) can be administered at 6 weeks and the second at 10 weeks of age in a two-dose schedule. Any of the available rotavirus vaccine may be administered. Inactivated influenza vaccine (either trivalent or quadrivalent) is recommended annually to all children between 6 months to 5 years of age. Measles-containing vaccine (MMR/MR) should be administered after 9 months of age. Additional dose of MR vaccine may be administered during MR campaign for children 9 months to 15 years, irrespective of previous vaccination status. Single dose of Typhoid conjugate vaccine (TCV) is recommended from the age of 6 months and beyond, and can be administered with MMR vaccine if administered at 9 months. Four-dose schedule of anti-rabies vaccine for Post Exposure Prophylaxis as recommended by World Health Organization in 2018, is endorsed, and monoclonal rabies antibody can be administered as an alternative to Rabies immunoglobulin for post-exposure prophylaxis.

Impact of a dedicated neonatal stabilization room and process changes on stabilization time.

OBJECTIVE: Our objective was to evaluate the impact of a dedicated resuscitation and stabilization (RAS) room and process changes on infant stabilization time. STUDY DESIGN: A prospective quality improvement study was conducted on preterm infants in a tertiary care center. A dedicated RAS room, preresuscitation huddle, infant-isolette-ventilator pairing and improved documentation were implemented. The primary outcome was median time to stabilization and secondary outcomes were illness severity on day 1 and morbidity at discharge. RESULTS: A sustained reduction in median time to stabilization from 90 min in the preimplementation phase to 72 min in the sustainability phase was observed. All planned and iterative process changes were integrated into the RAS team's daily routine. Time to completion of procedures decreased, illness severity and morbidity remained unchanged. CONCLUSION: A dedicated RAS room adjacent to the delivery suite in conjunction with process changes improves efficiency of care.

A comparison of the Miller laryngoscope versus the prototype neonatal offset-blade laryngoscope in a manikin.

Laryngoscope blades used to intubate newborn babies are relatively bulky and frequently exert high pressure on the upper jaw. We tested a prototype neonatal offset-blade laryngoscope (NOBL) developed to overcome these limitations. Our aims were to compare the pressure on the upper jaw exerted by a size 0 Miller laryngoscope and the NOBL on a neonatal manikin, as well as the time taken to intubate the trachea and the area of view of the larynx. Twenty healthcare professionals with more than five years of experience in neonatal intensive care took part; the findings were assessed using pressure-sensitive film and photographs. High-pressure indentation occurred in 17 (85%) attempts using the Miller versus 1 (5%) using the NOBL (p = 0.0001). The median (IQR [range]) pressure exerted with the Miller laryngoscope was 455 (350-526 [75-650]) kPa vs 80 (0-133 [0-195]) kPa with the NOBL (p < 0.0001). The area of pressure exerted with the Miller laryngoscope was 68 (32-82 [0-110]) mm(2) vs 8 (0-23 [0-40]) mm(2) with the NOBL (p < 0.0001). The time to intubate was 8.3 (7.3-10.1[4-19]) s for the Miller and 8.0 (5.6-9.6 [4-13.5]) s for the NOBL (p < 0.0001). The area of view blocked by the Miller laryngoscope was 38% of the oral orifice versus 12% with the NOBL. We conclude that the NOBL significantly reduced undesired pressure on the upper jaw during tracheal intubation and improved the view of the larynx compared with a conventional laryngoscope.

Nevirapine-related adverse events among children switched from efavirenz to nevirapine as compared to children who were started on nevirapine-based antiretroviral therapy directly.

In this retrospective study, incidence of nevirapine (NVP) toxicity in children who were switched from efavirenz (EFV) to NVP (treatment experienced [TE] group) was compared with that of children who had started NVP-based antiretroviral therapy directly (treatment naïve [TN] group). This study also identified risk factors associated with development of NVP toxicity in children. The incidence and risk of developing NVP toxicities were significantly higher in TE when compared to TN group. Median duration of onset of NVP toxicity from the initiation was 2.14 and 3.84 weeks in TE and TN children, respectively. Mean CD4 count was found to be significantly higher in children who developed toxicity (577 ± 81 cells/µL) as compared to the children who did not develop toxicity (403 ± 29 cells/µL). Similarly, children in TE group who developed NVP toxicity had higher mean CD4 cell count than children in TN with NVP toxicity. The risk factors for the development of NVP toxicity include female gender with CD4 count >250 cells/µL and TE children especially girls with CD4% >15% and boys with CD4 count >400 cells/µL. To conclude, the higher incidence of NVP toxicity among TE group warrants a cautious approach while switching the NVP- from EFV-based therapy.

Assessment of the severity of visible blood in the stool using a cluster of neonatal cases -a quality improvement study.

BACKGROUND: Non-availability of an established validated tool to assess and monitor the severity of visible blood in a stool (VBS) specimen over time, prevents effective decision making about discontinuation of contact precautions and hospital discharge. OBJECTIVE: To determine the impact of implementing a VBS investigation, parent apprisal template and Visible Blood in the Stool -Assessment Tool (VBS-AT) on standardized reporting and the evaluation of clinical improvement. METHODS: A prospective quality improvement cohort study was conducted in a tertiary, neonatal unit. All infants with isolated VBS without clinical signs, radiological pneumatosis and abnormal laboratory results were included. The template and VBS-AT instrument were implemented at the bedside. Criteria for discontinuation of contact precautions and readiness for discharge home were defined apriori. RESULTS: Eight infants developed VBS during the cluster lasting ten days. Seventy-four (78%) of the 98 episodes were graded by the VBS-AT. Five of the six infants had a maximum VBS grade of 3. The duration of VBS and contact precautions ranged from 4-38 days. All six infants with a VBS grade ≤2 for 4 consecutive days did not deteriorate beyond grade ≥3 or develop gastrointestinal complications during the ten week period following the end of the cluster. Consistent objective reporting of the severity of VBS and consistent evaluation of infants' progress over time contained the cluster effectively and facilitated discharge of stable infants. CONCLUSIONS: Implementation of a tool to standardize, investigate and objectively monitor the severity of VBS is feasible and improves effectiveness of care at no extra cost.

Primary microcephaly gene MCPH1 shows signatures of tumor suppressors and is regulated by miR-27a in oral squamous cell carcinoma.

Mutations in the MCPH1 (microcephalin 1) gene, located at chromosome 8p23.1, result in two autosomal recessive disorders: primary microcephaly and premature chromosome condensation syndrome. MCPH1 has also been shown to be downregulated in breast, prostate and ovarian cancers, and mutated in 1/10 breast and 5/41 endometrial tumors, suggesting that it could also function as a tumor suppressor (TS) gene. To test the possibility of MCPH1 as a TS gene, we first performed LOH study in a panel of 81 matched normal oral tissues and oral squamous cell carcinoma (OSCC) samples, and observed that 14/71 (19.72%) informative samples showed LOH, a hallmark of TS genes. Three protein truncating mutations were identified in 1/15 OSCC samples and 2/5 cancer cell lines. MCPH1 was downregulated at both the transcript and protein levels in 21/41 (51.22%) and 19/25 (76%) OSCC samples respectively. A low level of MCPH1 promoter methylation was also observed in 4/40 (10%) tumor samples. We further observed that overexpression of MCPH1 decreased cellular proliferation, anchorage-independent growth in soft agar, cell invasion and tumor size in nude mice, indicating its tumor suppressive function. Using bioinformatic approaches and luciferase assay, we showed that the 3'-UTR of MCPH1 harbors two non-overlapping functional seed regions for miR-27a which negatively regulated its level. The expression level of miR-27a negatively correlated with the MCPH1 protein level in OSCC. Our study indicates for the first time that, in addition to its role in brain development, MCPH1 also functions as a tumor suppressor gene and is regulated by miR-27a.

Oncogenic microRNA-155 down-regulates tumor suppressor CDC73 and promotes oral squamous cell carcinoma cell proliferation: implications for cancer therapeutics.

The CDC73 gene is mutationally inactivated in hereditary and sporadic parathyroid tumors. It negatively regulates ß-catenin, cyclin D1, and c-MYC. Down-regulation of CDC73 has been reported in breast, renal, and gastric carcinomas. However, the reports regarding the role of CDC73 in oral squamous cell carcinoma (OSCC) are lacking. In this study we show that CDC73 is down-regulated in a majority of OSCC samples. We further show that oncogenic microRNA-155 (miR-155) negatively regulates CDC73 expression. Our experiments show that the dramatic up-regulation of miR-155 is an exclusive mechanism for down-regulation of CDC73 in a panel of human cell lines and a subset of OSCC patient samples in the absence of loss of heterozygosity, mutations, and promoter methylation. Ectopic expression of miR-155 in HEK293 cells dramatically reduced CDC73 levels, enhanced cell viability, and decreased apoptosis. Conversely, the delivery of a miR-155 antagonist (antagomir-155) to KB cells overexpressing miR-155 resulted in increased CDC73 levels, decreased cell viability, increased apoptosis, and marked regression of xenografts in nude mice. Cotransfection of miR-155 with CDC73 in HEK293 cells abrogated its pro-oncogenic effect. Reduced cell proliferation and increased apoptosis of KB cells were dependent on the presence or absence of the 3'-UTR in CDC73. In summary, knockdown of CDC73 expression due to overexpression of miR-155 not only adds a novelty to the list of mechanisms responsible for its down-regulation in different tumors, but the restoration of CDC73 levels by the use of antagomir-155 may also have an important role in therapeutic intervention of cancers, including OSCC.

Early-onset neonatal sepsis: rate and organism pattern between 2003 and 2008.

OBJECTIVE: Organisms causing early-onset neonatal sepsis (EONS) have consistently changed over time. The distribution of organisms in EONS helps to influence the appropriate type of antibiotic prophylaxis strategy during labor and the antibiotics used in neonates with suspected sepsis. STUDY DESIGN: To compare the organisms distribution for EONS between 2003 and 2008 for infants admitted to neonatal intensive care units (NICUs) in Canada. Data were retrieved from infants with a positive bacterial blood or cerebrospinal fluid culture in the first 72 h after birth who were admitted to NICUs participating in the Canadian Neonatal Network from 2003 to 2008. Comparisons of incidence rate, demographics and causative organisms were carried out between earlier cohort (2003 to 2005) and later cohort (2006 to 2008). RESULT: A total of 405 infants had positive blood and/or cerebral spinal fluid cultures over the study period. The EONS rate was 6.8/1000 admissions (n=24969) in the earlier cohort compared with 6.2/1000 admissions (n=37484) in the later cohort (P=0.36). Rate of clinical chorioamnionitis was higher in the later cohort (38 vs 26%; P=0.02). For term infants, coagulase-negative Staphylococcus (CONS) (2.4/1000) followed by group B Streptococcus (GBS) (1.9/1000) were the most common organisms identified. For preterm infants, CONS (2.5/1000) followed by Escherichia coli (2.6/1000) were the most common organisms identified. There was a significant reduction in GBS EONS over time (P<0.01) and a trend toward an increase in other organisms. CONCLUSION: Although the rate of EONS among neonates admitted to NICUs has not changed, the pattern of infection has changed over the past 6 years. With the increased use of prophylactic antibiotics to mothers, careful surveillance of the changing trend of bacterial organisms among neonates is warranted.
