Altered Prevalence of Pulp Diagnoses in Diabetes Mellitus Patients: A Retrospective Study

IntroductionDiabetes mellitus (DM) is a complex multisystemic disorder that affects an estimated 21 million Americans. No studies have evaluated the association of DM with the prevalence of each pulpal diagnosis. The objective of this study was to compare the prevalence of each pulp diagnosis including symptomatic irreversible pulpitis (SIP), asymptomatic irreversible pulpitis, reversible pulpitis, normal pulp, and pulp necrosis (PN) in DM patients against a nondiabetic control group.MethodsA retrospective chart review was approved by Rutgers University Institutional Review Board. The prevalence of the diagnoses SIP, asymptomatic irreversible pulpitis, reversible pulpitis, normal pulp, and PN was calculated from AxiUm (Exan software, Las Vegas, NV) electronic health records at Rutgers School of Dental Medicine. The chi-square test was used to see the relationship between the 2 categoric variables. Second, binary logistic regression analyses were performed for each group.ResultsA total of 2979 teeth were diagnosed with a pulp condition between April 2013 and November 2018. The total tooth number of DM patients was 682, whereas the tooth number of nondiabetic patients was 2297. In the subgroup of patients younger than 40 years old, SIP was notably more prevalent in DM patients. In addition, the prevalence of PN in elderly DM patients (60–69 years old) was significantly higher than in the control group.ConclusionsThe prevalence of SIP in DM patients was significantly higher compared with the control group (<40 years old), suggesting the possibility that DM could hypersensitize the subgroup of patients younger than 40 years old to pulpitis pain.     

Overweight and obese youth with type 1 or type 2 diabetes share similar elevation in triglycerides during middle and late adolescence

BackgroundOverweight and obesity have been observed in children with type 1 diabetes (T1D). This further increases their future risk of Cardiovascular Disease (CVD) as well as the development of other risk factors, such as dyslipidemia.AimsTo compare lipid profiles in children and adolescents with Type 1 diabetes and lean mass (T1L), Type 1 diabetes and overweight or obese (T1OW/OB), and type 2 diabetes (T2D).MethodsThis was a cross-sectional study of 669 patients with T1D or T2D aged 2–19 years using retrospective data collected from 2003 to 2014. Included patients were categorized into lean (BMI < 85th ile and overweight or Obese (BMI ≥ 85th ile). Patients were subcategorized into three age groups: < 10 years, 10–14 years, and 15–19 years.Results7.6% of patients had T2D. Of the patients with T1D, 58.9% were lean, 26.4% were overweight, and 14.7% were obese. Total Cholesterol (TC), Low-density lipoprotein cholesterol (LDL-C) and Non-HDL-C levels were similar across groups. In the 15–19 years group, Triglycerides (TG) levels were significantly higher in T1OW/OB and similar to T2D. High-density lipoprotein Cholesterol (HDL-C) was significantly lower in T2D. Weight status significantly correlated with TG and HDL-C levels in T1D and T2D groups.ConclusionsT1OW/OB constitutes a significant proportion of the T1D population. Patients with obesity and T1D, especially if in their late adolescence, have an adverse lipid profile pattern that is comparable to adolescents with T2D. Based on these findings, risk for future CVD in T1OW/OB and T2D may be equivalent.

目的 探讨奥美拉唑三联疗法治疗小儿消化性溃疡的临床疗效.方法 选择2020年1月—2021年1月在新郑市中医院就诊治疗的90例消化性溃疡患儿,按照入院先后顺序将所有患儿分为对照组和治疗组,每组各45例.对照组采用雷尼替丁三联疗法进行治疗:口服盐酸雷尼替丁胶囊,3～5 mg/(kg·d),2次/d;口服克拉霉素缓释片,15～20 mg/(kg·d),2次/d;口服阿莫西林胶囊,30～50 mg/(kg·d),2次/d.治疗组采用奥美拉唑三联疗法进行治疗:口服奥美拉唑肠溶胶囊,0.6～0.8 mg/(kg·d),1次/d;克拉霉素缓释片、阿莫西林胶囊用法用量均与对照组相同.两组患儿治疗6周.观察两组患儿的临床疗效,比较两组患儿治疗前后的炎性因子水平、胃肠道激素水平.结果 治疗后,治疗组患儿的总有效率(93.33％)高于对照组(77.78％),组间比较有显著差异(P<0.05).治疗后,两组患儿血清白细胞介素-25(IL-25)、C反应蛋白(CRP)、肿瘤坏死因子-α(TNF-α)水平均明显降低,有统计学差异(P<0.05);治疗后治疗组患儿血清IL-25、CRP、TNF-α水平均低于对照组,组间比较有显著差异(P<0.05).治疗后,两组患儿血清胃动素(MTL)、胃泌素(GAS)水平均明显降低,生长抑素(SS)水平明显升高,有统计学差异(P<0.05);治疗后治疗组患儿血清MTL、GAS水平低于对照组,SS水平高于对照组,组间比较差异有显著差异(P<0.05).治疗后,治疗组患儿的幽门螺杆菌根除率为91.11％,高于对照组的幽门螺杆菌根除率77.77％;治疗组患儿溃疡愈合率为80.00％,高于对照组的溃疡愈合率62.22％,组间比有显著差异(P<0.05).结论 奥美拉唑肠溶胶囊三联疗法治疗患儿消化性溃疡具有较好的临床效果,可减轻患儿的炎性反应、调节胃肠道激素,安全性较高,值得临床上借鉴.     

Diabetic foot ulcers: A devastating complication of diabetes mellitus continues non-stop in spite of new medical treatment modalities

Diabetic foot ulcer is a devastating complication of diabetes mellitus and significant cause of mortality and morbidity all over the world and can be complex and costly. The development of foot ulcer in a diabetic patient has been estimated to be 19%-34% through their lifetime. The pathophysiology of diabetic foot ulcer consist of neuropathy, trauma and, in many patients, additional peripheral arterial disease. In particular, diabetic neuropathy leads to foot deformity, callus formation, and insensitivity to trauma or pressure. The standard algorithms in diabetic foot ulcer management include assessing the ulcer grade classification, surgical debridement, dressing to facilitate wound healing, off-loading, vascular assessment (status and presence of a chance for interventional vascular correction), and infection and glycemic control. Although especially surgical procedures are sometimes inevitable, they are poor predictive factors for the prognosis of diabetic foot ulcer. Different novel treatment modalities such as nonsurgical debridement agents, oxygen therapies, and negative pressure wound therapy, topical drugs, cellular bioproducts, human growth factors, energy-based therapies, and systematic therapies have been available for patients with diabetic foot ulcer. However, it is uncertain whether they are effective in terms of promoting wound healing related with a limited number of randomized controlled trials. This review aims at evaluating diabetic foot ulcer with regard to all aspects. We will also focus on conventional and novel adjunctive therapy in diabetic foot management.     

Bone regeneration in critical-sized mandibular symphysis defects using bioceramics with or without bone marrow mesenchymal stem cells in healthy,diabetic, osteoporotic,and diabetic-osteoporotic rats

ObjectivesTo compare new bone formation in mandibular critical-sized bone defects (CSBDs) in healthy, diabetic, osteoporotic, and diabetic-osteoporotic rats filled with bioceramics (BCs) with or without bone marrow mesenchymal stem cells (BMSCs).MethodsA total of 64 adult female Sprague-Dawley rats were randomized into four groups (n = 16 per group): Group 1 healthy, Group 2 diabetic, Group 3 osteoporotic, and Group 4 diabetic-osteoporotic rats. Streptozotocin was used to induce type 1 diabetes in Group 2 and 4, while bilateral ovariectomy was used to induce osteoporosis in Group 3 and 4. The central portion of the rat mandibular symphysis was used as a physiological CSBD. In each group, eight defects were filled with BC (hydroxypatatite 60% and β-tricalcium phosphate 40%) alone and eight with BMSCs cultured on BC. The animals were sacrificed at 4 and 8 weeks, and the mandibles were processed for micro-computed tomography to analyze radiological union and bone mineral density (BMD); histological analysis of the bone union; and immunohistochemical analysis, which included immunoreactivity of vascular endothelial growth factor (VEGF) and bone morphogenetic protein 2 (BMP-2).ResultsIn all groups (healthy, diabetics, osteoporotics, and diabetics-osteoporotics), the CSBDs filled with BC + BMSCs showed greater radiological bone union, BMD, histological bone union, and more VEGF and BMP-2 positivity, in comparison with CSBDs treated with BC alone (at 4 and 8 weeks).ConclusionsApplication of BMSCs cultured on BCs improves bone regeneration in CSBDs compared with application of BCs alone in healthy, diabetic, osteoporotic, and diabetic-osteoporotic rats.
