RESUMEN
INTRODUCTION: Adrenocortical carcinoma (ACC) is associated with a poor prognosis. We reviewed the National Cancer Database (NCDB) to analyze the prognostic factors in surgically resected ACC patients and the association of surgical approaches with overall survival (OS). METHODS: A retrospective NCDB (2004-2014) review of patients undergoing curative-intent surgical resection for ACC was performed. Effects of patient demographics, tumor characteristics, histopathology, and perioperative course on OS were analyzed. Log-rank statistics were used to associate clinical variables with OS. The multivariable Cox proportional hazard model included only statistically significant variables. RESULTS: A total of 1599 patients with ACC were included. A majority of patients were female (60.73%) and presented with a Charlson-Deyo score of zero (75.42%). A majority of the ACC cases were Grade 3 (45.69%), and almost a third (30.64%) underwent margin-positive resections. Univariate analysis demonstrated a decrease in OS associated with increasing age and comorbidities. A negative resection margin and lack of lymphovascular invasion predicted better OS. Multivariable analysis showed that age, grade, surgical resection margins, and hospital length of stay were associated with OS. CONCLUSIONS: Advanced age, grade, presence of lymphovascular invasion, and positive surgical margins predicted a worse overall survival for adrenocortical cancer in our analysis. Resection with negative margins improves outcomes.

Demineralized freeze-dried bone allograft (DFDBA) has been used extensively in periodontal therapy. Questions have been raised however, about the osteogenic potential of the variety of grafts available. In India the cost factor is another important consideration. The aim of this study therefore was to evaluate the clinical efficiency of the low priced, indigenously prepared DFDBA obtained from the Tata Memorial Hospital (TMH) Tissue Bank, in periodontal regeneration in infrabony periodontal defects, as compared to DFDBA obtained from the Pacific Coast Tissue Bank (DEMBONE). The latter was used as the control. 16 patients with bilaterally similar periodontal infrabony defects were selected, and randomly allotted to the test and control groups. At baseline, using standardized protocol, recession, probing depths (PD), and clinical attachment levels (CAL) were measured, following which periodontal surgery was carried out, with placement of the respective graft materials. Patients were recalled after 6 months for re-assessment. Statistically significant improvement was obtained for PD reduction and CAL gain for both groups (p < 0.05). However, no significant difference was observed between the test and control groups. It was therefore concluded that both the materials from different tissue banks are equally effective clinically, with the test material being additionally cost effective.

UNLABELLED: Diabetes mellitus (DM) is undiagnosed in approximately half of the patients actually suffering from the disease. In addition, the prevalence of DM is more than twice as high as in patients with periodontitis when compared to periodontally healthy subjects. Thus, a high number of patients with periodontitis may have undiagnosed DM. The purpose of the present study was to evaluate whether blood oozing from a gingival crevice during routine periodontal examination can be used for determining glucose levels. MATERIALS AND METHODS: Observational cross-sectional studies were carried out in 75 patients (43 males and 32 females) with chronic periodontitis who were divided into two groups: Group I and Group II, respectively. Blood oozing from the gingival crevices of anterior teeth following periodontal probing was collected with the stick of glucose self-monitoring device, and the blood glucose levels were measured. At the same time, finger-prick blood was taken for glucometric analysis and subsequent readings were recorded. RESULTS: The patient's blood glucose values ranged from 74 to 256 mg/dl. The comparison between gingival crevicular blood and finger-prick blood showed a very strong correlation, with a t value of 3.97 (at P value = 0.001). CONCLUSIONS: The data from this study has shown that GCB collected during diagnostic periodontal examination can be an excellent source of blood for glucometric analysis.

AIM: To assess and contrast the effectiveness of systemic doxycycline and diode laser as supplements to scaling and root planing (SRP) in terms of clinical and microbiological parameters. MATERIALS AND METHODS: A total of 33 patients diagnosed with periodontitis stages II and III were included and randomized into group A (SRP + diode laser), group B (SRP + doxycycline), and group C (SRP alone). Selected sites were assessed for clinical and microbial parameters-plaque index (PI), gingival index (GI), pocket probing depth (PPD), relative attachment level (RAL), and colony-forming units (CFUs). Every clinical parameter was noted at baseline and after three months. The arithmetic mean, followed by the standard deviation, was calculated for the required assessment intervals. Analysis of variance (ANOVA) was used to compare all parameters between groups, and if the results of the ANOVA test were significant, post hoc analysis was performed. For intragroup comparison, student t-tests were performed. RESULTS: The clinical parameters significantly improved within three months for all groups. In terms of relative attachment level, a statistically significant difference (P < 0.001) was obtained at the three-month interval compared to the baseline value, with the most statistically significant difference seen in group A (3.36±0.50 to 0.64±0.50), followed by group B (3.18±0.40 to 2.18±0.40). The mean pocket probing depth observed at three months, compared to the baseline value, showed a statistically significant difference (P < 0.001) in group A (5.91±0.70 to 2.18±0.40) compared to group B (6.18±0.75 to 4.36±0.50), followed by group C (5.82±0.75 to 5.27±0.64). CONCLUSION: The use of diode laser-assisted pocket disinfection and systemic doxycycline, in addition to scaling and root planing, has proven to be efficient for treating periodontal pockets.
RESUMEN
Background C-reactive protein (CRP) is the first acute-phase protein and is an exceptional investigative marker for local and systemic inflammation. The periodontitis severity grading scale (PSGS) indicates the extent of periodontal inflammation. Therefore, the aim of the study was to explore the correlation between the markers of systemic and periodontal inflammation as assessed by CRP and the PSGS in participants with periodontitis. Materials and methods The present study enrolled 85 systemically healthy participants with periodontitis. PSGS and CRP levels were measured in each participant. Descriptive and inferential statistics were applied for analysis. Results The PSGS scores ranged from 24 to 213, and the CRP levels ranged from 0.5 to 3.23 mg/l. This shows a positive correlation between the periodontal scale and CRP. A nonsignificant (p-value > 0.05) correlation exists between age and CRP score, and a significant association was seen between gender and severity of periodontitis with p-value < 0.02. A highly significant association between gender and CRP score was found with p-value < 0.001. Conclusion The level of serum CRP dramatically increased with the severity of periodontitis. The results of this study point to a highly significant correlation between markers of systemic and periodontal inflammation, as well as a strength of association between the two markers.
RESUMEN
Primary splenic pregnancy is an extremely rare form of extra tubal ectopic pregnancy. Trans-arterial embolization is emerging as an effective treatment for ectopic pregnancy. Here, we present a 34-year-old G4P3003 woman who presented with vaginal bleeding and elevated serum quantitative human chorionic gonadotropin (beta-hCG). After initial workup showed no intrauterine pregnancy, MRI of the abdomen showed an ectopic gestational sac at the splenic hilum. A preoperative splenic artery embolization was performed successfully prior to open splenectomy for removal of the ectopic pregnancy to minimize operative blood loss. By sharing our experience in this case, we contribute to the validation of trans-arterial embolization as an effective adjunctive measure in treating ectopic pregnancy.
RESUMEN
BACKGROUND: This study aimed to evaluate the effect of scaling and root planing (SRP) on levels of plasma C-reactive protein (CRP). METHODS: A total of 30 patients with advanced periodontitis as determined by Clinical Periodontal Sum Score (CPSS) were recruited. Venous whole blood samples were drawn to obtain serum samples from all participants at baseline and 1 month after SRP (post-SRP). High-sensitivity CRP (hs-CRP) was measured by highly sensitive immunoturbidimetric assay. Wilcoxon signed-rank test was used for data analysis. Spearman rank correlation analysis was conducted to test the correlations between CPSS and hs-CRP at baseline and post-SRP. RESULTS: There was a statistically significant reduction in the post-SRP CPSS values from the baseline values (z = 4.783, p < 0.0001). Similarly, there was a statistically significant reduction in the post-SRP hs-CRP levels from the baseline levels (z = 4.782, p < 0.0001). Moreover, there was positive association between the baseline levels of CPSS and hs-CRP (ρ = 0.5703) and the post-SRP values of CPSS and hs-CRP (ρ = 0.7507). CONCLUSION: The present study suggests that SRP can significantly reduce the levels of CRP.

The role of vitamin D in maintaining gum well-being is crucial. However, scientific research reported that the connotations of cholecalciferol and periodontal health have been divested in the present literature. However, there is enormous heterogeneity in the data available. The current review aims to systematically review and appraise the available literature investigating the role of vitamin D in maintaining periodontal health. Studies included randomized controlled trials and clinical trials following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and cohort studies reporting associations between vitamin D and oral health in systemically healthy patients. Databases such as PubMed, Google Scholar, Scopus, Embase, and other sources, including hand search, were searched until May 2023 using together-equipped search sequences. Altogether, scientific articles that conform to the inclusion principles underwent a thorough eminence evaluation. All papers meeting inclusion criteria were subject to quality assessment, and the method used to assess the risk of bias was the Cochrane risk of bias tool. The search identified 1883 papers, among which 1435 were excluded after title evaluation. After abstract and title screening, 455 were excluded, and six full texts were assessed. After full-text evaluation, two articles were excluded, and only four were included. The data shows vitamin D's association with oral health maintenance. Along with its action on bone metabolism, it has extended function, which provides for its action as an anti-inflammatory agent and production of anti-microbial peptides, which help maintain oral health. Although the literature available is immense, there is enormous heterogenicity in the papers conducted to appraise the association between vitamin D and oral health. This systematic review has filtered all the data to review a few essential aspects of the role of vitamin D in maintaining oral physiology. Vitamin D has a linear relationship with periodontal health; however, the evidence is insufficient, and further studies must be done.
RESUMEN
Aim: The main focus of the study is to determine the difference between the efficacy of xenogeneic collagen matrix (XCM) versus platelet-rich fibrin (PRF) adjunct to coronally advanced flap to treat the gingival recession. Background: Because of esthetic concerns or root hypersensitivity, typical necessity dictates for buccal gingival recession treatment. This study was planned to evaluate and compare the efficacy of XCM with PRF in the treatment of the recessed gingiva. Materials and Methods: Thirty-four sites with Cairo's RT1 and RT2 gingival recessions were taken, out of which 17 sites received XCM (test) and 17 sites received PRF (control). A periodontal treatment was performed first, followed by a re-evaluation. All clinical measurements, including recession height (RH), recession width (RW), clinical attachment level (CAL), keratinized tissue width, and keratinized tissue thickness, were taken before surgery (baseline) and at a 6-month interval following periodontal surgery. Landry's healing index was also measured at the 1st and 2nd weeks after surgery. Results: None of the acquired data implies a significant difference statistically for CAL, RW, RH, thickness, and width of keratinized tissue (WKT) at 6-month interval between both the groups. Comparison of healing at the 1st and 2nd week intervals among both the groups showed no statistical significance. No significant difference among both Groups A and B was seen according to the intergroup analysis in terms of periodontal parameters such as CAL (P = 0.374), RW (P = 0.542), RH (P = 0.890), WKT (P = 0.877) and thickness of keratinized tissue (P = 0.547), and Landry's healing index (P = 0.429). Conclusion: In consideration of the patient's comfort and the method's simplicity, it can be concluded that PRF or XCM can be employed as an alternative.
RESUMEN
Variations of the biliary system present challenges to abdominal operations and can affect postoperative outcomes. Bile leak is an uncommon complication of total gastrectomy. However, any procedure that involves mobilisation of the left lobes of the liver should be executed with additional caution. A thorough assessment including preoperative imaging for aberrant anatomy should be performed, especially aberrant bile ducts in the left triangular ligament. Ligation or suturing of the left triangular ligament should be considered when the aberrant anatomy suggests, to decrease the risk of postoperative bile leak. In addition, the left lateral segment of the liver should be thoroughly inspected on initial completion of the operation.

OBJECTIVE: The objective of this review was to synthesize the best available research evidence regarding the effectiveness of tree nuts on glycemic outcomes in adults with type 2 diabetes mellitus. INTRODUCTION: There has been an increase in the use of complementary therapy, particularly botanical products, for management of type 2 diabetes mellitus. It has been reported that increasing mono- and polyunsaturated fatty acids in diet effectively lowers the risk of development of type 2 diabetes mellitus. Hence, it was hypothesized that consumption of nuts, which are high in polyunsaturated fatty acids and mono-unsaturated fatty acids, may aid in preventing diabetes and reducing levels of blood glucose by reducing glycemic load by displacing dietary carbohydrates present in diet. INCLUSION CRITERIA: This systematic review included randomized controlled trials that compared the consumption of any type and form of tree nut with a placebo or any other intervention in adults with type 2 diabetes mellitus. Trials were included if they measured fasting blood glucose, postprandial blood glucose, and/or glycated hemoglobin. Trials that assessed triglyceride levels and weight postintervention were also considered for inclusion. Trials were restricted to the English language. METHODS: A three step search of PubMed, CINAHL, Embase, Trip database, and Cochrane Central Register of Controlled Trials (CENTRAL) was done in July 2019. To find unpublished studies, ClinicalTrials.gov and Google Scholar were searched. Studies from the search were reviewed against the inclusion criteria by two reviewers. The JBI critical appraisal checklist for randomized controlled trials was used to assess the potential studies for methodological quality. A meta-analysis and subgroup analysis was conducted among trials with the same type of intervention and outcome measures. Results are presented in a narrative format where statistical pooling was not possible. RESULTS: Fifteen trials were included with a total sample size of 667. Consumption of pistachios demonstrated a significant reduction in triglyceride levels (mmol/L) at three month or earlier follow-up (mean difference [MD] -0.28; confidence interval -0.33, -0.23; Pâ<0.00001). The meta-analysis including all tree nuts combined showed reduction in both fasting blood glucose and glycated hemoglobin (MD -0.26âmmol/L and -0.11% respectively) at three month or earlier follow-up. The subgroup analysis demonstrated MD of -0.45, -0.16, and -0.90âmmol/L in fasting blood glucose following ingestion of walnuts, almonds, and hazelnuts, respectively, and -0.17% in glycated hemoglobin following ingestion of walnuts at three month or earlier follow-up. Although not clinically significant, these figures give an indication that further research with larger sample sizes and longer follow-up may show encouraging results. CONCLUSIONS: The authors found that pistachio consumption for three months or less significantly reduced triglyceride levels. Other tree nuts (walnuts, almonds, and hazelnuts) reduced fasting blood glucose and glycated hemoglobin levels by varying degrees. Further robust randomized controlled trials with power calculation-based sample size, comparing same type, dose, and method of nut intervention, will provide more evidence. For now, clinical decisions should be based on standard practice local guidelines. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42019133558.

INTRODUCTION: The use of plants for treating diseases is as old as the human species. Medicinal plants have been a major source of therapeutic agents for alleviation and cure of diseases. OBJECTIVES: The objective of the study was to evaluate and compare the antifungal activity of garlic, cinnamon, lemongrass and tulsi in powder and oil form at different concentrations on Candida albicans. MATERIALS AND METHODS: Powder and oil of garlic, cinnamon, lemongrass and Tulsi dissolved in inert solvent dimethyl formamide to obtain different concentration. Stock solution of different concentration was inoculated on Petri plates containing C. albicans and incubated at 30°C for 48 h. The inhibition zones were measured in millimeters using Vernier caliper. The collected data were analyzed using statistical test like mean value and one-way analysis of variance. RESULTS: Maximum zone of inhibition for the C. albicans was 42 mm at concentrations of 50% for the oil of lemongrass; followed by cinnamon 40 mm, garlic 24 mm and tulsi 20 mm. The P value obtained 0.050, 0.040, 0.036 and 0.031 were found to be statically significant for C. albicans at 20%, 30%, 40% and 50% concentrations of the various oil preparations, respectively. The P value obtained 0.043, 0.033, 0.032 and 0.027 were found to be statically significant for C. albicans at 20%, 30%, 40% and 50% concentrations of various plant powder, respectively. CONCLUSIONS: Lemongrass and cinnamon oil shows best antifungal effect against C. albicans as compared to garlic and tulsi. Compared to powder preparations, the oil preparations are better to inhibit the growth and higher the concentrations, greater the zone of inhibition seen in all the plant extracts and in oil.
RESUMEN
Heart failure (HF) and myocardial infarction are serious complications of major noncardiac surgery in older adults. Many factors can contribute to the development of HF during the postoperative period. The incidence of, and risk factors for, procedure-associated heart failure (PHF) occurring at the time of, or shortly after, medical procedures in a population-based sample ≥ 65 years of age have not been fully characterized, particularly in comparison with HF not proximate to medical procedures. This analysis comprises 5,121 men and women free of HF at baseline from the Cardiovascular Health Study who were followed up for 12.0 years (median). HF events were documented by self-report at semi-annual contacts and confirmed by a formal adjudication committee using a review of the participants' medical records and standardized criteria for HF. Incident HF events were additionally adjudicated as either being related or unrelated to a medical procedure (PHF and non-PHF, respectively). We estimated cause-specific hazards ratios for the association of covariates with PHF and non-PHF. There were 1,728 incident HF events in the primary analysis: 168 (10%) classified as PHF, 1,526 (88%) as non-PHF, and 34 unclassified (2%). For those 1,045 participants in whom LV ejection fraction was known at the time of the HF event, it was ≥45% in 89 of 118 participants (75%) with PHF, compared to 517 of 927 participants (55%) with non-PHF (p < 0.001). Increased age, male gender, diabetes, and angina at baseline were associated with both PHF and non-PHF (range of hazard ratios (HR): 1.04-2.05]. Being Black was inversely associated with PHF [HR: 0.46, 95% confidence interval: 0.25-0.86]. Participants with increased age, without baseline angina, and with baseline LVEF<55% were at a significantly lower risk for PHF compared to non-PHF. Among those with PHF, surgical procedures-including cardiac, orthopedic, gastrointestinal, vascular, and urologic-comprised 83.3%, while percutaneous procedures comprised 8.9% (including 6.5% represented by cardiac catheterizations and pacemaker placements). Another group composed of a variety of procedures commonly requiring large fluid volume administration comprised 7.7%. There was a lower all-cause 30-day mortality in the PHF versus the non-PHF group (2.2% vs 5.7%), with a nonsignificant odds ratio of 0.39 in a minimally adjusted model. When individuals with prior myocardial infarction (MI) were excluded in a sensitivity analysis, the proportion of incident HF with concurrent MI was greater for PHF (32.9%) than for non-PHF (19.8%). In conclusion, PHF in older adults is a common entity with relatively low 30-day mortality. Baseline angina, lower age, and LVEF ≥ 55% were associated with a higher risk of PHF compared to non-PHF. Being Black was associated with a lower risk of PHF and PHF as a proportion of HF was lower in Black than in non-Black participants. Compared to non-PHF, PHF more frequently presented with concurrent MI and with preserved LV ejection fraction.

Transformation of research into clinical practice is the most challenging step in evidence based dental practice. Designing the most reliable research with applicable endpoint evaluation is very important as it can lead to successful research outcomes that can be accepted in clinical practice. In the periodontal research few accepted endpoints are used frequently as they are believed to be the gold standard in measuring the periodontal disease and the treatment outcomes. However, a wide range of endpoints used are surrogate endpoints and these endpoints have no direct correlation with the patient centered outcomes. Hence, a direct relationship of surrogate endpoints with true endpoints needs to be established. This review highlights the importance of true endpoints and challenges in implementing these in clinical research. Importance of patient's centered outcomes are also reviewed and duly discussed here. Need for conducting research which includes the true endpoints or the surrogate endpoints with clinical applicability and tangible outcomes, was also suggested in this review.
RESUMEN
BACKGROUND: One of the most common aesthetic problem encountered in the field of periodontology is gingival recession, which is, perceived by the patients as increase in length of teeth. The treatment of buccal gingival recession is a common requirement due to aesthetic concern or root sensitivity. This study was planned to evaluate the efficacy of PRF membrane compared to that of CTG in Miller's class I gingival recessions. MATERIALS AND METHODS: 32 sites with Miller's Class I gingival recessions, out of which 16 sites received PRF (test) and 16 sites received CTG (control). Each patient had undergone an initial periodontal treatment, including oral hygiene instructions, plaque control, and scaling and root planing, followed by re-evaluation. All clinical recordings; recession height, recession width, clinical attachment level, height of keratinized tissue, thickness of keratinized tissue, healing index and pain perception, were performed immediately before surgery (baseline) and after 6 months interval following periodontal surgery. RESULTS: In the test group, significant improvement was seen in terms CAL, REC-HT, REC-WD, HKT and TKT from baseline to 6 months. In the control group, only significant improvement seen was in REC-HT and TKT from baseline to 6 months. Comparison of both Healing Index and VAS score was done and it showed no significant difference between test and the control group except VAS at 1 week. CONCLUSION: Though CTG is a gold standard procedure, PRF can be used as an alternative procedure by keeping patient's comfort and recognition in mind.
RESUMEN
BACKGROUND: The aim of the present meta-analysis is to determine the efficacy of tetracycline group of antibiotics as local drug delivery agents in the treatment of chronic periodontitis. MATERIALS AND METHODS: MEDLINE, EBSCO, Cochrane database, and Google Scholar were used to identify studies in English published up to January 31, 2017. An additional hand search of relevant journals and of the bibliographies of the paper identified was also performed. Articles retrieved were screened using specific inclusion criteria by two independent reviewers. Randomized control trials investigating the effect of tetracycline group of antibiotics as local drug delivery agents in chronic periodontitis were included in the study. RESULTS: Ten relevant articles were selected for the meta-analysis, of which five articles were retrieved after electronic search, three articles were included after hand search, and two unpublished articles were included. The number of patients in studies ranged from 13 to 140 sites with mean age ranging from 20 to 75. A total of 588 sites were treated using tetracycline group of antibiotics as local drug delivery agents in the treatment of chronic periodontitis. The meta-analysis showed standard difference in mean -1.02 mm (95% confidence interval [CI] 0.28, 1.75) for clinical gain in attachment in favor of tetracycline group. Standard difference in mean for probing depth (PD) was 1.20 mm (95% CI 0.57, 1.87) in tetracycline group. CONCLUSION: The results of this meta-analysis showed a significant improvement in periodontal parameters such as CAL, PD, and sulcular bleeding index in favor of tetracycline as local drug delivery compared to placebo.
RESUMEN
Asthma is one of the most common respiratory diseases affecting all age groups. The world is now trying to identify some dietary factors which can play a preventive role. We performed this systematic review and meta-analysis of RCTs to assess the effect of intake of polyunsaturated fatty acid (PUFA) in infancy and/or childhood on incidence of asthma or wheezing episodes. We searched MEDLINE, EBSCO, Trip, and Google Scholar up to January 31, 2015. All RCTs where infants or children who were given omega-3 fatty acid supplementation and which reported incidence of asthma and/or wheezing episodes as dichotomous outcomes were included in this review. Random effects model was used for pooling the risk estimates. Total five articles were included. Most of them were from Australia. On meta-analysis, the pooled estimate of odds ratios by random effects model showed no significant change in incidence of asthma after supplementation of omega-3 FA in infancy or childhood (OR 0.974; CI 0.646, 1.469; p = 0.900). We concluded that a multicentric RCT is required to assess the effect of omega-3 FA supplementation exclusively to infants or children to predict the best time of omega-3 FA supplementation to prevent asthmatic or wheezing episodes later in life.
RESUMEN
INTRODUCTION: Several bone graft materials have been used in the treatment of infrabony defects. Demineralized freeze-dried bone allograft (DFDBA) has been histologically proven to be the material of choice for regeneration. However, platelet-rich fibrin (PRF) has been said to have several properties that aid in healing and regeneration. Hence, this study focuses on the regenerative capacity of PRF when compared with DFDBA. MATERIALS AND METHODS: A total of 40 sites with intrabony defects were selected and were assigned to the test group (open flap debridement [OFD] and PRF, n = 20) and the control group (OFD + DFDBA, n = 20). At the test sites, two PRF plugs were placed in the intrabony defect after debridement of the site and flap was sutured in place. The parameters measured were probing depth (PD), relative attachment level (RAL), and gingival marginal level (GML). These parameters were measured just before surgery (baseline) and at 6 months postsurgery. The changes in PD, RAL, and GML were analyzed at baseline and postsurgically after 6 months in each group with paired t-test and between the two groups with unpaired t-test. RESULTS: The mean reduction in PD after 6 months in the test PRF group is 3.67 ± 1.48 mm where in control DFDBA group is 3.70 ± 1.78 mm. Gain in RAL in the test PRF group is 2.97 ± 1.42 mm where in control DFDBA group, it is 2.97 ± 1.54 mm. Gingival margin migrated apically in the test PRF group by 0.43 ± 1.31 mm where in control DFDBA group by 0.72 ± 2.3 mm. It was seen that the differences in terms of PD (P = 0.96), RAL (P = 1.00) and GML (P = 0.62) were not significant. CONCLUSION: Platelet-rich fibrin has shown significant results after 6 months, which is comparable to DFDBA for periodontal regeneration in terms of clinical parameters. Hence, it can be used in the treatment of intrabony defects.
RESUMEN
Diabetes mellitus (T2DM) has become a global problem. Role of n-3 FA in its prevention is still not completely understood. We carried out this systematic review and meta-analysis to assess the relation of dietary intake of fish and n-3PUFA with risk of diabetes. We searched PUBMED, EMBASE and GOOGLE with cross references to identify relevant articles. Since no RCTs were available, we searched for prospective cohort studies. Sixteen studies with 6,79,763 participants which assessed the association of dietary intake of fish and n-3 PUFA (marine or alpha-linolenic acid) with incidence of T2DM in > 18 years population and provided relative risk (RR) or hazard ratio (HR) with the corresponding 95% confidence interval (CI) of T2DM for each category of fish or n-3 PUFA intake were included. Three independent reviewers reviewed all eligible studies and abstracted the relevant information from individual studies. Meta-analysis confirmed the previous finding that marine n-3 FA increased risk of T2DM in Americans but reduced the same in Asians. We observed that two and seven times increased intake of ALA and fatty fish respectively reduced the risk of T2DM significantly and ALA did not increase the risk in Americans. We concluded that ALA may have some role in preventing T2DM, but is not studied widely. Hence, it should be studied in greater details (with higher degrees of intake; more than two times) to aid in developing effective preventive strategies against diabetes.

Glandular odontogenic cyst (GOC) is an uncommon developmental odontogenic cyst of jaws with a relative frequency between 0.012 and 1.3%. GOC is very rare and only 111 cases have been documented in the English literature so far. Generally, this cyst is encountered in the anterior areas of the mandible and is more common with a wide age range, the mean age being 49.5 years and has a tendency to recur. GOC is often misdiagnosed because of its overlapping histopathological features with that of other odontogenic cysts such as lateral periodontal cyst (LPC) or botryoid cyst and central low-grade Mucoepidermoid carcinoma. Histopathological diagnosis and differential diagnosis of GOC is challenging for pathologist. Here, we present a case of GOC in a 40 year old male patient in left mandibular region that crossed the midline.
