Refractory angiolymphoid hyperplasia with eosinophilia: Complete resolution with low dose thalidomide.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a difficult-to-treat and rare benign vascular proliferative condition which presents as painless, solitary, or multiple vascular papules or nodules in the head and neck area, with predilection for the ear. We report a case of ALHE that failed multiple therapeutic interventions but achieved complete resolution when treated with thalidomide.

A Shift to Synergistic Surface Treatment Using Laser to Enhance the Bonding of Zirconia to Veneering Ceramic: An In Vitro Study.

AIM: The aim of this study was to evaluate the effect of combination of surface treatment using laser along with other modalities of surface treatment on shear bond strength of zirconia to veneering ceramic. MATERIALS AND METHODS: Milled and sintered zirconia cylinders (n = 150) were used in the study which were divided into six groups that were subjected to various surface treatments. Samples in group I were subjected to sandblasting. In group II Laser (Er: YAG) surface treatment was performed. Samples in group III were subjected to sandblasting followed by laser ablation. In group IV laser ablation was carried out followed by liner application, and samples in group V were subjected to laser ablation followed by argon plasma treatment. Instron machine was used to test the shear bond strength (SBS). One-way ANOVA and Bonferroni test were used for statistical analysis. RESULT: Samples in group III showed highest values for SBS followed by groups I, IV, and V with less SBS value for group II. CONCLUSION: Thus, the results conclude the use of combination of surface treatment using laser to be an effective modality to enhance the shear bond strength of zirconia. CLINICAL SIGNIFICANCE: Synergistic surface treatment using laser increases the bond strength of zirconia prosthesis to veneering ceramic improving its clinical longevity.

Pyrimidine-2,4-dione targets STAT3 signaling pathway to induce cytotoxicity in hepatocellular carcinoma cells.

Signal transducer and activator of transcription 3 (STAT3) is a tumorigenic transcription factor that is persistently activated in various human cancers including hepatocellular carcinoma (HCC). Therefore, STAT3 is considered as a prominent target to counteract the uncontrolled proliferation of cancer cells. In the present report, pyrimidine-2,4-diones (N-methyluracil derivatives) (MNK1-MNK14) were synthesized in an ionic liquid (BMIm PF6) medium employing a ligand-free Suzuki-Miyaura cross-coupling process. Among the 14 derivatives, compound MNK8 showed good cytotoxicity towards both the tested cell lines and did not display a toxic effect against normal hepatocytes (LO2). MNK8 significantly increased the Sub-G1 cell count in both cell lines and the cytotoxic effect of MNK8 was found to be mediated through the suppression of constitutive phosphorylation of STAT3Y705. It also decreased the DNA interaction ability of nuclear STAT3 in HCC cells. MNK8 downregulated the levels of apoptosis-related proteins (such as Bcl-2, cyclin D1, survivin) and increased cleaved caspase-3 inferring the apoptogenic effect of MNK8. It also reduced the CXCL12-triggered cell migration and invasion in in vitro assay systems. Overall, MNK8 has been demonstrated as a new inhibitor of STAT3 signaling cascade in HCC cells.

Microhealth insurance and the risk coping strategies for the management of illness in Karnataka: a case study.

Risk coping strategies adopted by the households in the event of illness depends on the accessibility to healthcare financing mechanisms including health insurance. The empirical evidence on the effect of microhealth insurance (MHI) on the risk coping strategies of the households is scarce. This paper evaluates the impact of Sampoorna Suraksha Program, a nongovernmental organization-initiated MHI scheme and the risk coping strategies of households faced with medical illness in Karnataka state, India. In this descriptive cross-sectional study, we collected data from 416 insured households, 366 newly insured households and 364 uninsured households in randomly selected 10 taluks in three districts of Karnataka state, India. We hypothesized that insured individuals rely less on ex post risk coping strategies (borrowing, use of savings and sale of assets) compared with uninsured and newly insured individuals. Our hypothesis was tested using logistic and linear regression analysis. A significant difference among insured, uninsured and newly insured individuals was found for borrowing but not in the use of savings or sale of assets. A positive impact of MHI on illness-induced borrowing (both incidence and amount) was evident. The evidence from this study reinforces the role of MHI as a pivotal financing alternative to out-of-pocket expenditure in India.

Clinical and microbiological efficacy of systemic roxithromycin as an adjunct to non-surgical periodontal therapy in treatment of chronic periodontitis. A randomized, double-blinded, placebo-controlled clinical trial.

PURPOSE: The objective of this randomized clinical trial was to evaluate the clinical and microbiological effects of systemic administration of roxithromycin (RXM) as an adjunct to non-surgical periodontal therapy (NSPT) in the treatment of individuals with moderate to severe chronic periodontitis (CP). METHODS: 70 individuals (38 males and 32 females, aged 25 to 60 years) with moderate to severe CP were randomly allocated into two groups. 35 individuals were allocated to full mouth SRP+RXM while 35 individuals were allocated to SRP+ Placebo group. The clinical parameters evaluated were probing depth (PD), clinical attachment level (CAL), gingival index (GI), plaque index (PI) and % bleeding on probing sites (%BOP) at baseline (B/L), 1-, 3- and 6-month intervals while microbiologic parameters included percentage of sites positive for periodontopathic bacteria A. actinomycetemcomitans, P. gingivalis and T. forsythia at B/L, 3 and 6 months using polymerase chain reaction. RESULTs: Both groups showed improved clinical and microbiologic parameters over 6 months. RXM group showed a statistically significant reduction in mean PD and CAL gain as compared to the placebo group (P < 0.0001). There was reduction in percentage of sites positive for periodontopathic bacteria over the duration of the study in both groups and a statistically significant reduction in the number of sites positive for A. actinomycetemcomitans in RXM group (P < 0.001).

Clinical evaluation of the periodontal health condition and oral health awareness in Parkinson's disease patients.

OBJECTIVE AND BACKGROUND: The objectives were to compare periodontal status between subjects with and without Parkinson's disease (PKD) to determine the influence of PKD on periodontal disease. This study was conducted to evaluate the relationship of periodontal status with severity of PKD. MATERIALS AND METHODS: This study was conducted on 45 subjects with PKD (subjects with PKD were divided into 5 groups from group 2 to group 6 according to Hoehn and Yahr stages) and 46 control subjects (group 1). Probing depth (PD), clinical attachment level (CAL), gingival index (GI), plaque index (PI) and percentage of bleeding sites (%BoP) were evaluated. All subjects were interviewed regarding their practice of oral hygiene and access to professional dental care. RESULTS: There were statistically significant differences in PD, CAL, GI, PI and %BoP in subjects with PKD and controls (p < 0.001). All the evaluated periodontal clinical parameters and indices deteriorate with increase in severity of PKD. The mean PD value increased from 2.75 mm for group 1 to 6.17 mm for group 6, and mean CAL value increased from 3.14 mm for group 1 to 6.74 mm for group 6. The mean GI, PI and %BoP values increased from 0.55, 1.35 and 20.37 to 2.66, 3.80 and 70.86, respectively with increasing severity of PKD. CONCLUSION: There is a need for dental care and encouragement to use plaque control methods for subjects with PKD as periodontal pathology presented a high prevalence even in the early stages of PKD.

Correlation of human S100A12 (EN-RAGE) and high-sensitivity C-reactive protein as gingival crevicular fluid and serum markers of inflammation in chronic periodontitis and type 2 diabetes.

OBJECTIVE: The aim of the present study was to evaluate the levels and correlation of human S100A12 and high-sensitivity C-reactive protein (hs-CRP) in gingival crevicular fluid (GCF) and serum in chronic periodontitis (CP) subjects with and without type 2 diabetes mellitus (DM). MATERIALS AND METHODS: A total of 44 subjects were divided into three groups: group 1 had 10 periodontally healthy subjects, group 2 consisted of 17 CP subjects and group 3 had 17 type 2 DM subjects with CP. GCF and serum levels of human S100A12 and hs-CRP were quantified using enzyme-linked immunosorbent assay and immunoturbidimetric analysis, respectively. The clinical outcomes evaluated were gingival index, probing depth and clinical attachment level and the correlations of the two inflammatory mediators with clinical parameters were evaluated. RESULTS: Both human S100A12 and hs-CRP levels increased from group 1 to group 2 to group 3. The GCF and serum values of both these inflammatory mediators correlated positively with each other and with the periodontal parameters evaluated (p < 0.05). CONCLUSION: Human S100A12 and hs-CRP can be considered as possible GCF and serum markers of inflammatory activity in CP and DM.

Clinical and microbiological effects of levofloxacin in the treatment of Aggregatibacter actinomycetemcomitans-associated periodontitis: a randomized placebo-controlled clinical trial.

AIM: To evaluate the clinical and microbiological effects of systemic levofloxacin (LFX) in subjects with Aggregatibacter actinomycetemcomitans-associated chronic periodontitis (AA-ACP). MATERIALS AND METHODS: Subjects with severe periodontitis with subgingival detection of A. actinomycetemcomitans were randomly divided into two treatment groups; a test group (n = 35) that received scaling and root planing (SRP) and LFX (500 mg o.d.) and a control group (n = 34) that received SRP and placebo (o.d.) for 10 days. Plaque index (PI), gingival index (GI), percent of sites with bleeding on probing (% BoP), probing depth (PD) and clinical attachment level (CAL) were recorded and subgingival plaque samples were cultivated for detection of A. actinomycetemcomitans at baseline to 6 months at various intervals. RESULTS: Subjects receiving LFX showed the greatest improvements in mean PD and CAL. The difference in the reduction of PD and CAL in the two groups was significant at 1, 3 and 6 months for PD and 3 and 6 months for CAL (p < 0.05). The inter-group difference in PI, GI and % BoP was not significant at any interval. Detectable levels of A. actinomycetemcomitans were significantly less in the test group 3 and 6 months post-therapy. CONCLUSION: Systemic LFX as an adjunct to SRP improves clinical outcomes and suppresses A. actinomycetemcomitans below detectable levels.

Association of metabolic syndrome and periodontal disease in an Indian population.

BACKGROUND: Metabolic syndrome, the whole of interconnected factors, presents with local manifestation, such as periodontitis, related by a common factor known as oxidative stress. The aim of the present study was to assess the association between metabolic syndrome and periodontal disease in an Indian population. METHODS: Clinical criteria for metabolic syndrome included 1) abdominal obesity; 2) increased triglycerides; 3) decreased high-density lipoprotein cholesterol; 4) hypertension or current use of hypertension medication; and 5) high fasting plasma glucose. Serum C-reactive protein (CRP) levels were also measured. Periodontal parameters including gingival index (GI) average and deepest probing depth (PD) and clinical attachment level (CAL) were recorded on randomly selected quadrants, one maxillary and one mandibular. Based on the presence or absence of metabolic syndrome, individuals were divided into two groups. RESULTS: The periodontal parameters PD, CAL and GI differed significantly between the two groups. The GI values in Group 1 (2.06 ± 0.57) were greater than in Group 2 (1.79 ± 0.66; p = 0.0025). Similarly PD and CAL values in Group 1 (4.58 ± 1.69 and 2.63 ± 1.61 mm) were significantly greater (p < 0.001) than in Group 2 (3.59 ± 1.61 and 1.61 ± 1.40 mm, respectively). Also, three metabolic components and serum CRP correlated with average PD, and the strength of the correlation was medium in Group 1 as compared to Group 2, in which it was weak. CONCLUSION: The association between metabolic syndrome and periodontal disease was significant, and abdominal obesity appeared to be the most important contributing metabolic factor to periodontal disease.

Treating Dehiscence During Implant Placement and Loading on Angled Abutment in Maxillary Lateral Incisor Region: A Case Report.

The primary factor causing recession is the morphology and anatomy of the dentition. The facial bony plate overlying the root is usually very thin. The complete absence of bone over the facial root surface is referred to as dehiscence. Such buccal bone defects in case of implant dentistry threaten the survival of dental implant. Many surgical techniques are introduced to enhance alveolar bone volume for placing the dental implants. Guided bone regeneration (GBR) is one such established surgical technique for correcting buccal dehiscence defects, along with the use of various barrier membranes for the same. This case report describes an implant placement in the maxillary left lateral incisor region showing dehiscence on the labial cortical plate, along with bone graft and GTR membrane.

Effect of Andrographis paniculata Herbal Extract on Cytotoxicity, Proliferation and Osteogenic/Odontogenic Differentiation of Human Dental Pulp Stem Cells: An In Vitro Study.

BACKGROUND: Research has been conducted to assess the regenerative potential of dental pulp stem cells (DPSCs) following pretreatment of stem cells with certain molecules, bioactive compounds, plant extract and physical stimulation. Andrographis paniculata (AP) herbal extract with important medicinal properties is proven to have a preosteogenic effect on osteoblasts. AIM: This study aimed to determine the effect of various concentrations of AP extract on the cytotoxicity and osteogenic and odontogenic potential of DPSCs. METHODS AND MATERIAL: Dental pulp stem cells were subjected to treatment with various concentrations of AP herbal extract (7 ug/ml, 5.2 ug/ml, 3.5 ug/ml, 1.7 ug/ml and 0.8 ug/ml), following which the cells were subjected to tests-3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) analysis for cytotoxicity and real-time reverse transcriptase-polymerase chain reaction (RT-PCR) test for expression of genes (bone morphogenetic protein (BMP), osteocalcin (OCN), dentin sialophosphoprotein (DSPP) and alkaline phosphatase (ALP)). RESULTS: AP extract at concentration of 0.8 ug/ml-5.2 ug/ml had no cytotoxicity supporting cell growth. 3.5 ug/ml showed significant upregulation of genes on the third day. CONCLUSION: AP, a commonly occurring medicinal plant through its effect on DPSCs, could serve as an effective pretreatment modality for cell-based regenerative therapy and vital pulp therapy.

Effect of Laser Photobiomodulation on Postoperative Pain in Endodontics: A Systematic Review.

Objective: Photobiomodulation therapy has proven benefits in various dental treatments. The current systematic review aims to explore the role of laser photobiomodulation in modulating postoperative pain followed by endodontic treatment. Methods: In this systematic review, randomized controlled clinical trials on low-level laser therapy/photobiomodulation in endodontic therapy were analyzed. Database search was performed in PubMed/Medline, Web of Science, Scopus, and Cochrane Library, followed by literature search in Google Scholar. Results: A total of 12 studies were included as per the set criteria. The included studies utilized diode laser (808-970 nm) and indium gallium aluminum. All the included studies evaluated postendodontic pain after root canal therapy and endodontic surgery. A majority of the included studies showed significant benefits of photobiomodulation in postoperative pain management in endodontic therapy.Heterogeneity of the laser parameters and lack of power calculations for sampling among the included studies preclude solid recommendation of use of photobiomodulation therapy (PBMT) for postendodontic pain management. Conclusions: Although PBMT has proven potential benefits being a possible adjunct in postoperative pain management in endodontic therapy, it requires robust standardized randomized control trials to confirm the results of the systematic review.

Comparative evaluation of autologous platelet-rich fibrin and platelet-rich plasma in the treatment of mandibular degree II furcation defects: a randomized controlled clinical trial.

BACKGROUND: The treatment of molar furcation defects remains a considerable challenge in clinical practice. The identification of clinical measurements influential to treatment outcomes is critical to optimize the results of surgical periodontal therapy. The present study aimed to explore the clinical and radiographical effectiveness of autologous platelet-rich fibrin (PRF) and autologous platelet-rich plasma (PRP) in the treatment of mandibular degree II furcation defects in subjects with chronic periodontitis. MATERIAL AND METHODS: Seventy-two mandibular degree II furcation defects were treated with either autologous PRF with open flap debridement (OFD; 24 defects) or autologous PRP with OFD (25), or OFD alone (23). Clinical and radiological parameters such as probing depth, relative vertical clinical attachment level and horizontal clinical attachment level along with gingival marginal level were recorded at baseline and 9 mo postoperatively. RESULTS: All clinical and radiographic parameters showed statistically significant improvement at both the test sites (PRF with OFD and PRP with OFD) compared to those with OFD alone. Relative vertical clinical attachment level gain was also greater in PRF (2.87 ± 0.85 mm) and PRP (2.71 ± 1.04 mm) sites as compared to control site (1.37 ± 0.58 mm), and relative horizontal clinical attachment level gain was statistically significantly greater in both PRF and PRP than in the control group. CONCLUSIONS: The use of autologous PRF or PRP were both effective in the treatment of furcation defects with uneventful healing of sites.

A randomized controlled clinical trial on the clinical and microbiological efficacy of systemic satranidazole in the treatment of chronic periodontitis.

OBJECTIVE: The present clinical trial was designed to investigate the effectiveness of systemic satranidazole (SZ) as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis. METHODS: Sixty-six subjects presenting with at least twelve teeth with probing depth (PD) > or = 4 mm were selected. Thirty-three subjects were randomly assigned to full-mouth SRP + placebo (Group 1) and 33 subjects were assigned to full-mouth SRP + SZ (Group 2). The clinical outcomes evaluated were plaque index (PI), gingival index (GI), clinical attachment level (CAL) and PD at baseline, 1 month, 3 months and 6 months. Also, microbial analysis of dental plaque using polymerase chain reaction was done at baseline, 3 and 6 months to estimate the number of sites harboring periodontopathogens. RESULTS: Sixty subjects were evaluated up to 6 months. At 6 months, Group 2 showed greater mean reduction (3.84 +/- 1.31 mm) in PD as compared to Group 1 (1.42 +/- 1.01 mm; p < 0.05) and there was a greater mean CAL gain (3.22 +/- 1.01 mm) in Group 2 as compared to Group 1 (1.15 +/- 1.49 mm; p < 0.05). These subjects also showed significant reductions in the number of certain periodontopathogens, such as Tannerella forsythia, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. CONCLUSION: The systemic use of SZ, when used as an adjunct to non-surgical periodontal therapy in subjects with periodontitis, achieves significantly better clinical and microbiological results than scaling and root planing alone.

Prevalence, Metabolic Profile, and Associated Risk Factors of Non-alcoholic Fatty Liver Disease in an Adult Population of India.

Introduction Non-alcoholic fatty liver disease (NAFLD) is the main cause of chronic liver disease worldwide. NAFLD refers to a group of diseases that includes simple steatosis, nonalcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma. Unfortunately, there aren't many studies on NAFLD conducted in India. The majority of research involved specific populations, such as diabetics, pregnant women with gestational diabetes, and obese or non-obese people. When the current study was being planned, there were few population-based studies available. In almost all of the research, ultrasound was employed to identify NAFLD, and the whole spectrum of NAFLD was not assessed. The full spectrum of NAFLD in India must have been considered, including all stages of steatosis as well as hepatic damage as shown by high alanine aminotransferase levels and fibrosis. The purpose of this study was to determine the prevalence, spectrum, and metabolic determinants of NAFLD as assessed by FibroScan® (FibroScan® expert 630 machine; Echosens, Paris, France) in adults of Central India. Methods This cross-sectional study was conducted among 236 adults aged 18 years and above in three localities of Bhopal, India from March 2022 to October 2022. The study included males and females who provided informed consent and fulfilled inclusion criteria. One research assistant and one staff nurse solicited people to participate in the FibroScan® test during the community screening and shared information about the programme. All participants were subjected to the FibroScan® test. Results A total of 322 healthy adults were approached for possible inclusion in the study. Data from 236 subjects were available for analysis after meeting the inclusion and exclusion criteria. According to this study, 43.6% of the study population had NAFLD as detected by FibroScan®. Out of the total, 12.7% of subjects had steatosis grade 1 (S1), 12.3% of subjects had steatosis grade 2 (S2), and 18.6% of subjects had steatosis grade 3 (S3). High body weight, high waist circumference, high waist-to-hip ratio, high fasting sugar, high serum glutamate pyruvate transaminase (SGPT), high triglyceride levels and high very low-density lipoprotein (VLDL) levels were significantly associated with NAFLD. Conclusion In conclusion, 43.6% of the adult population of Bhopal, India is suffering from NAFLD. NAFLD is a severe burden in the Indian community despite being historically associated with the western world. Obesity, diabetes and dyslipidemia are significantly associated with NAFLD.

Efficacy of chlorhexidine, metronidazole and combination gel in the treatment of gingivitis--a randomized clinical trial.

OBJECTIVE: Effective plaque control is essential for prevention of gingivitis and periodontitis. The aim of this 24-week follow-up parallel study was to evaluate the efficacy of three topical gels in the treatment of gingivitis as compared to placebo gel. METHODS: One hundred twenty subjects diagnosed with chronic generalized gingivitis were selected and randomly divided into four groups: Group 1--placebo gel, Group 2--chlorhexidine (CHX) gel, Group 3--metronidazole (MTZ) gel and Group 4--chlorhexidine-metronidazole (CHX-MTZ) gel. Clinical evaluation was undertaken using the gingival index (GI) of Löe and Silness and the plaque index (PI) at baseline, 6 weeks, 12 weeks and 24 weeks. Microbiological analysis was also done at the same time intervals. A subjective evaluation was also undertaken by questionnaire. RESULTS: Groups treated with all three gels (CHX, MTZ and CHX-MTZ) showed significant clinical and microbiological improvement as compared to the group treated with a placebo gel. The reduction in PI, GI and microbiological count in the group treated with the CHX-MTZ combination gel was significant when compared to those treated with CHX and MTZ gels. CONCLUSION: Topical application of CHX or MTZ alone or in combination may have a role in the management of gingivitis.

Microbiological outcomes of systemic ornidazole use in chronic periodontitis. Part II.

OBJECTIVE: Antimicrobials are increasingly being used as adjuncts to non-surgical or surgical periodontal therapy. The main purpose of the present analysis was to evaluate the effect of systemic ornidazole (ORN) on total anaerobic microbial counts of subjects with moderate to advanced chronic periodontitis (CP). METHODS: This was a single-center, double-blinded, placebo-controlled, randomized clinical trial of six months duration. Fifty-eight subjects presenting with at least 12 teeth with probing depth (PD) > or = 4 mm were selected. Thirty subjects received full-mouth scaling and root planing (SRP) + placebo (control group) and 28 subjects received full-mouth SRP + ORN (test group). The total anaerobic counts were analyzed by collecting subgingival plaque from deepest pockets at baseline (B/L), 1 week, 1 month, 3 months and 6 months. RESULTS: Paired and unpaired t-tests were used to determine the inter- and intra-group differences. Fifty subjects were evaluated up to six months. There was a significant difference in the number of anaerobes in the two groups at all the intervals except B/L (p<0.05). CONCLUSION: The systemic use of ORN very efficiently reduced the microbial load in the group that received antibiotics.

Case Report: Chemoradiation with Paclitaxel and Carboplatin Unveiling Leprosy Type 1 Downgrading Reaction.

Type 1 lepra reaction (T1R) is a major complication seen in nonpolar forms of leprosy and leads to significant morbidity. The classification of T1R as up and downgrading, based on previously defined histopathological criteria (by Ridley), has therapeutic and prognostic implications. The trigger factors for these reactions are poorly described, especially in case of downgrading T1R and we describe a case of leprosy reaction that was possibly triggered by chemoradiation and elucidate the possible mechanism.

Effect of triple antibiotic paste and calcium hydroxide on the rate of healing of periapical lesions: A systematic review.

Aim: The rate of healing of periapical lesion after the antibacterial dressing with triple antibiotic paste and calcium hydroxide was assessed. Materials and Methods: Case reports which used triple antibiotic paste and calcium hydroxide as the intracanal dressing was searched in PubMed, Google Scholar and Cochrane Oral Health's Trials Register up to August 2020, without language and period restriction. Two authors independently reviewed all identified titles and abstracts for eligibility. Tables were generated to summarize the included studies. Results: Sixteen (n = 16) articles met the eligibility criteria. Nonsurgical endodontic treatment was carried out in eleven cases with triple antibiotic paste and in nineteen cases calcium hydroxide was used. Results of the study after analyzing the case reports indicate that both triple antibiotic paste and calcium hydroxide are equally effective as intracanal medicament. In cases where calcium hydroxide failed to eliminate symptoms, triple antibiotic paste was found to be effective. Conclusion: As far as the effect on the healing of the periapical lesions is concerned, all the studies showed a high success rate. Available scientific data indicates nonsurgical treatment can be adopted as a routine measure to conservatively treat large periapical lesions of endodontic origin.
