A new approach to the management of caliber‐persistent artery: A case report and analysis of previously reported cases

A caliber‐persistent labial artery (CPLA) is an incipient arterial branch that penetrates near the submucosal tissue of the lip without dividing or reducing in diameter and often appears as a palpable lesion on the lip. It occurs at an incidence of approximately 3%. This study investigated the causes of swelling of the lips, focusing on CPLA, and reviewed the literature for past cases in order to inform the treatment of a 32‐year‐old man presenting with an asymptomatic, solitary, elevated lesion on the vermilion of the upper lip of seven months duration. Biopsy resulted in abundant bleeding. Histopathology showed fragments of connective tissue composed of spindle‐shaped cells, fibroblasts, collagen fibers and sections of small blood vessels with lymphocytic infiltration of chronic inflammatory cells around the small vessels. A thick‐walled section reminiscent of a major artery was apparent. In view of the size of the lesion and concern over the functional and esthetic impairment that might result from surgery, the patient was treated with triamcinolone (40 mg/ml) injected at low pressure into the lesion, which caused the formation of deposits of colloidal particles within the lesion. The procedure was repeated twice at 2‐week intervals. Subsequently, the lesion was found to have completely regressed. The favorable therapeutic results achieved, and the findings of the present review, support the intralesional injection of triamcinolone as a first‐line conservative treatment in CPLA rather than a surgical approach that can result in inordinate hemorrhaging.     

Evaluation of FRC reinforcing on flexural strength of acrylic resin denture bases

Fractures of acrylic denture bases are a common problem in dentistry. Various reinforcement methods have been used to prevent recurrent fractures. The purpose of this study was to evaluate the flexural strength of two types of acrylic denture base resins--Meliodent and Acropars--reinforced with glass fibers. What we found was that the fracture load and flexural strength for the two types of acrylic bases were approximately similar and there was no statistically significant difference between them, which indicates that these types of acrylics are not efficient in fracture load and flexural strength. The use of FRC improved the flexural strength in acrylic bases.     

Molecular Anti-inflammatory Mechanisms of Retinoids and Carotenoids in Alzheimer’s Disease: a Review of Current Evidence

Alzheimer’s disease (AD) is considered as one of the most prevalent neurodegenerative disorders characterized by progressive loss of mental function and ability to learn. AD is a multifactorial disorder. Various hypotheses are suggested for the pathophysiology of AD including “Aβ hypothesis,” “tau hypothesis,” and “cholinergic hypothesis.” Recently, it has been demonstrated that neuroinflammation is involved in the pathogenesis of AD. Neuroinflammation causes synaptic dysfunction and neuronal death within the brain. Excessive production of pro-inflammatory mediators induces Aβ peptide production/accumulation and hyperphosphorylated tau generating inflammatory molecules and cytokines. These inflammatory molecules disrupt blood–brain barrier integrity and increase the production of Aβ42 oligomers. Retinoids and carotenoids are potent antioxidants and anti-inflammatory agents having neuroprotective properties. They are able to prevent disease progression through several mechanisms such as suppression of Aβ peptide production/accumulation, oxidative stress, and pro-inflammatory mediator’s secretion as well as improvement of cognitive performance. These observations, therefore, confirm the neuroprotective role of retinoids and carotenoids through multiple pathways. Therefore, the administration of these nutrients is considered as a promising approach to the prevention and/or treatment of AD in the future. The aim of this review is to present existing evidences regarding the beneficial effects of retinoids and carotenoids on AD’s risk and outcomes, seeking the mechanism of their action.

Effects of Egg Consumption on Blood Lipids: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Background: It is widely agreed that egg consumption only modestly influences serum lipid concentrations. However, there is no meta-analysis summarizing existing randomized controlled trials.

Objective: The purpose of this study was to conduct a meta-analysis of published randomized controlled trials to explore the quantitative effect of egg consumption on serum lipid concentrations.

Design: Online databases including MEDLINE, Proquest and Google Scholar were systematically searched. Studies that were published after 2000 and compared serum lipids concentrations in egg-consumers and non egg-consumers were included. The data were obtained from 28 studies. Weighted mean differences were calculated as the ultimate effect using random effects model.

Results: Overall, egg consumption increased total cholesterol (TC) by 5.60 mg/dL (95% CI: 3.11, 8.09; P<0.0001), low density lipoprotein-cholesterol (LDL-C) by 5.55 mg/dL (95% CI: 3.14, 7.69; P<0.0001) and high density lipoprotein-cholesterol (HDL-C) by 2.13 mg/dL (95% CI: 1.10, 3.16; P<0.0001) compared with the control group. Heterogeneity found between studies was explained partly by study design and participant response to dietary cholesterol. No effect of increased egg consumption on LDL-C:HDL-C and TC:HDL-C ratios, and triglyceride (TG) concentrations were found. No association was observed between number of eggs consumed per day or study duration and any of the serum lipid markers.

Conclusion: Consumption of egg increases total cholesterol, LDL-C and HDL-C, but not LDL-C:HDL-C, TC:HDL-C and TG compared with low egg control diets. To assess the risk of coronary events, future studies should focus on the postprandial effect of egg consumption and effects on coronary risk.     

Pemphigus vulgaris in Iran: a clinical study of 140 cases

BACKGROUND: Pemphigus vulgaris (PV) is a rare autoimmune blistering disease of the skin and mucous membranes. It varies in its clinical profile and epidemiologic characteristics in different parts of the world. OBJECTIVE: To determine the clinical features of PV in Iran in a prospective manner. METHODS: The study included 140 patients with newly registered PV attending our dermatology clinic between January 2003 and June 2004. RESULTS The mean age at the onset of the disease was 41.5 +/- 15.7 years, with a female to male ratio of 1.59 : 1. At presentation to our clinic, both skin and mucosal involvement was observed in 95 patients (67.9%). Cutaneous lesions without the involvement of the mucous membranes were seen in nine patients (6.4%), and exclusive mucosal involvement was present in 36 patients (25.7%). The most common initial localization of the disease was the oral cavity, which was involved in 93 patients (77.5%). The most frequent cutaneous and mucosal sites involved were the thorax and oral cavity, respectively. CONCLUSION: Although minor differences were noted, the results of this study are in relatively good agreement with the literature with regard to the age, gender, and initial presentation of PV in Iran. Some skin sites, such as the scalp, thorax, and axilla, may be more commonly affected in men. Patients with initial mucosal lesions were significantly younger than those with initial cutaneous involvement. Mucosal lesions other than the oral mucosa may be more common than previously thought.     

Dairy products consumption and the risk of hypertension in adults: An updated systematic review and dose–response meta-analysis of prospective cohort studies

AimsWith an increase in the number of published prospective cohort studies, we sought to summarize the relationship between dairy products consumption and the risk of hypertension (HTN).Data synthesisWe searched PubMed, Web of Science, Embase, Science direct, and Scopus. Pooled RRs and 95% CIs were calculated using a random effects model. The certainty of the evidence was assessed by Grading of Recommendations Assessment, Development and Evaluation (GRADE). Sixteen studies were included in the current meta-analysis. We found an inverse association between total dairy products (RR = 0.90; 95% CI: 0.87, 0.94; n = 16), low-fat dairy products (RR = 0.86; 95% CI: 0.77, 0.96; n = 8), milk (RR = 0.94; 95% CI: 0.90, 0.99; n = 11), and fermented dairy (RR = 0.95; 95% CI: 0.91, 0.99; n = 8) consumption and the risk of HTN. However, in subgroup analysis, despite a significant association for total dairy products in women, Americans, longer and larger studies, and self-reported HTN, no associations were found in males, Europeans, or Asians, and studies which followed participants for <10 years or had <3000 participants or measured HTN. Dose–response analysis revealed a non-linear association between total dairy products and milk consumption and the risk of HTN, but a linear association for low-fat dairy products.ConclusionsHigher dairy products consumption was associated with reduced risk of HTN. This association was dependent on sex, geographical region of study, and the stage of HTN. However, the certainty of the evidence was graded either as low or very low.     

Interleukin 10 gene promoter polymorphisms (rs1800896, rs1800871 and rs1800872) and haplotypes are associated with the activity of systemic lupus erythematosus and IL10 levels in an Iranian population

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with unknown aetiology. According to the role of interleukin 10 (IL10) in SLE pathogenesis, the genetic alterations in its promoter region could be associated with elevated IL10 levels and exacerbated disease. Here, we investigated the association of genotype and haplotype frequencies of three IL10 gene promoter polymorphisms with susceptibility to SLE, IL10 plasma levels and disease activity of patients in an Iranian population. A total of 116 SLE patients and 131 healthy subjects were enrolled. The PCR‐RFLP technique was used to detect IL10 promoter genotypes at the positions of ?1082 (G/A), ?819 (C/T) and ?592 (C/A) in association with IL10 plasma levels and SLEDAI scores. The GG genotype of ?1082 polymorphism was associated with the increased risk of SLE [OR = 2.65, 95% CI (1.21–5.82), p‐value = 0.046]. The CC genotype in ?819 region was associated with SLE susceptibility [OR = 3.38, 95% CI (1.26–9.07), p‐value = 0.034] and C allele was introduced as risk allele [OR = 1.86, 95% CI (1.15–3.01), p‐value = 0.009] in this region. IL10 plasma levels were overexpressed in CC genotype carriers of ?592 SNP and decreased in AA genotype carriers of ?1082. IL10 was also increased in SLE patients with CGT (?592/?1082/?819) haplotype. The SLEDAI score was higher among CC genotype carriers at the position of ?592 and TT genotype carriers at the region of ?819. SLEDAI was also elevated among patients with CGC (?592/?1082/?819) and CAC (p = 0.011) haplotypes. The present study suggests that the IL10 –819(C/T), ?1082(G/A) and ?592(C/A) polymorphisms and the haplotypes are associated with SLE susceptibility, increased disease activity and elevated IL10 levels. While this is the first time to report such an association in an Iranian population, further studies are needed to confirm these findings.
