- Abstract
Cutaneous lymphadenoma is a rare tumor with distinctive histologic features. This entity was originally described as lymphoepithelial tumor by Santa Cruz and Barr in 1987. It was renamed cutaneous lymphadenoma in 1991. To date, at least 31 cases of this entity have been reported. The literature did not contain a clinical photograph of this lesion. A case of this rare tumor is described that includes clinical and histologic features. The literature regarding the unclear histogenesis of this distinctive tumor is reviewed. This report is one of a only few clinical illustrations of cutaneous lymphadenoma. Consistent with previous reports, the histologic findings in this case include basaloid proliferation and intraepithelial lymphocytes. The usual initial clinical diagnosis is basal cell carcinoma localized mainly to the head and neck area. The incidence is approximately equal in male and female patients. Excision of this benign neoplasm is curative. Controversy exists regarding the histogenesis of this tumor.

- Abstract
Objectives: Dental anxiety is a common phenomenon experienced by children in the dental setting. However, there is limited research on the effectiveness of cognitive-behavioral interventions in managing this anxiety. Therefore, the aim of this study was to evaluate the impact of a cognitive-behavioral psychologic intervention on dental anxiety in children. Materials and Methods: A total of thirty children, aged 7-10 years, underwent prophylaxis and fluoride therapy. The baseline anxiety levels of the children were determined using the Modified Child Dental Anxiety Scale (MCDAS). The intervention group (N=15) received two 30-minute sessions of cognitive-behavioral exercises. Additionally, a short film demonstrating a cooperative child undergoing pulpotomy was created and parents were instructed to show it to their children at home. During the treatment session, the exercises were reinforced at each step, and the MCDAS questionnaire was administered again. The children's behavior was also assessed using the Venham Clinical Cooperation Scale. Independent t-test, Mann-Whitney, chi-square, and Pearson's correlation coefficient were used for statistical analysis and P<0.05 was considered statistically significant. Results: Postoperatively, the MCDAS score in the intervention group was significantly lower compared to the control group. Notably, the intervention group demonstrated a downward trend in anxiety scores, while the control group showed an increase (P<0.001). Conclusion: Cognitive-behavioral interventions were found to be successful in decreasing dental anxiety in children undergoing pulpotomy. These interventions can be successfully implemented in clinical settings., Competing Interests: None declared., (Copyright © 2023 The Authors. Published by Tehran University of Medical Sciences.)

- Abstract
Introduction: Dental caries are considered as common health hazards and a serious lifelong threat to general health and quality of life. The present study aimed at identifying the impact of child dental caries and the associated factors on both child and family quality of life (QoL). Material and Methods . In this cross-sectional study, preschool children were selected randomly through clustered sampling from five educational districts in Tabriz, Iran, 2016. To assess the QoL related to oral health, the Early Childhood Oral Health Impact Scale (ECOHIS) was used. Clinical oral examination was performed to assess the presence of caries through the index of decayed, missing, and filled teeth (dmft). Descriptive and analytic statistical methods were used. To assess the underlying predictors of ECOHIS as a whole scale and the dimensions as a linear regression model were used as univariate and multivariate., Results: : Out of 756 children under 7 years old, 51.5% boys, mean (M) standard deviation (SD) of age 5.76 (0.78). About 85% of children had dental caries. The predictors of suboptimal ECOHIS related to both general and child dimensions were child age 6 year and above: r (756) = 2.43, and P ≤ 0.001, low-socioeconomic status: r (756) = 3.36 and P < 0.001 and high dmft: r (756) = 9.10 and P < 0.001. The predictors of suboptimal ECOHIS related to family domain were sex (girl): r (756) = 0.39 and P = 0.047; mother education (under12): r (756) = -0.92 and P < 0.001; mother job (employed) as univariate: r (756) = 0.71 and P = 0.002); and dmft: r (756) = -0.58 and P = 0.035., Conclusion: Adverse oral health of children imposes adverse effects on the QoL of children and families. Children's age, family socioeconomic level, presence of dental caries, child's gender, and mother's educational level were associated with the impact on QoL., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Marziyeh Shokravi et al.)

- Abstract
Sister Mary Joseph nodule (SMJN) is a rare metastasis to umbilical skin originating from internal tumors including the stomach, ovary and large intestine and less commonly from pancreatic cancers. We report an uncommon case of metastatic pancreatic adenocarcinoma to umbilical skin. An 85-year-old female presented with a 1.8 cm protrusion of the right lateral umbilicus. The CT scan showed a 3.5 cm pancreatic lesion, peritoneal carcinomatosis and abdominal lymphadenopathy. Histology examination revealed atypical infiltrative glandular structures. Immunohistochemistry showed positive CK7, negative CDX2 and P53 with mutated patterns. These were consistent with metastatic adenocarcinoma most consistent with pancreatobiliary or upper GI origin. CK7 expresses in the ductal cells in pancreatic ductal adenocarcinoma. While CDX2 is positive in intestinal-type adenocarcinoma, it is negative in pancreatic ductal adenocarcinoma. The diagnosis of adenocarcinoma is rendered based on the presence of a pancreatic lesion in CT scan, positive CK7 and negative CDX2 in umbilical nodule tumor cells in the current patient., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Aghighi et al.)

- Abstract
Purpose: The aim of this study was to evaluate the frequency of depressive and anxiety disorders in patients with carpal tunnel syndrome (CTS) after surgery in comparison with normal individuals., Materials and Methods: This cross-sectional analytical case-control study conducted on patients who underwent surgery with a diagnosis of carpal tunnel syndrome. In the first group, 35 patients with CTS who underwent surgery were randomly selected and evaluated for anxiety and depression with two standard questionnaires - of CES-D (Center for Epidemiologic Studies Depression) and S-TAI (Spielberger State-Trait Anxiety Inventory). The second group of 35 normal people were randomly selected and examined after matching the age and sex. The data were compared and analyzed using SPSS V.22 software., Results: The mean score of Spielberger state and trait anxiety and depression in the case group was higher than the control group (P < 0.001 and P = 0.003 respectively). In both age groups (< 40 and > 40 years) the level of state and trait anxiety and depression was significantly higher in case than the control group. In women, the level of state and trait anxiety and depression was significantly higher in the case group than in the control group, but in men, only trait anxiety was significant., Conclusion: The anxiety and depression disorders were more common in patients undergoing CTS than in normal individuals. Therefore, it is necessary to study the psychological status of these patients in the pre-discharge period and pay attention to its predictors in order to plan appropriate interventions.

- Abstract
Objective: The purpose of this cross-sectional study was to identify the oral health status and influencing factors in preschool children in Tabriz, Iran. A total of 756 children from 20% of the total district preschools were selected using a two-step random sampling procedure. Questionnaires were used to collect demographic and socio-economic data. Oral exams were conducted by a single pediatric dentist to assess the children's oral health, and to determine the number of decayed, missing, and filled teeth (dmft) according to the World Health Organization's (WHO) definition of caries., Results: Out of 756 preschool children, 51.5% boys with mean age of years 5.76 (SD = 0.78) were enrolled. The median (25th-75th Pertcentile) of dmft index in boys and girls was 4 (2-9) and 5 (2-8), respectively. Only 15.1% children had decay-free teeth. The results of univariate analysis showed a significant relationship between dmft index and child age (P < 0.001), mother's years of education (P = 0.001), mother's employment status (P < 0.001), and family socio-economic status (P < 0.001). On multivariate analysis, statistical significance was found in sex (P = 0.007), age groups except for 5 years (P = 0.210), mother's education status (P < 0.001) as well as in families with intermediate (P = 0.024), and high (P = 0.072) socio-economic status.

- Abstract
Objective: Dental anxiety, fear and phobia have different etiology, response patterns, time courses, and intensities that justify a clear distinction between these constructs. Differentiation of dental anxiety, fear or phobia in practice is a critical prerequisite for developing and implementing effective treatment for children. The aim of this study was to investigate whether current researches in the pediatric dentistry appropriately discriminate the central construct of dental anxiety, fear and phobia. We also highlighted the specific methodological issues in the assessment of these issues in pediatric dentistry., Study Design: A systematic search was conducted in Pubmed/medline and Scopus for articles which assessed dental anxiety, fear or phobia in children., Results: 104 research papers were included in the review that had made a distinction between dental anxiety, fear and phobia and had not used them interchangeably. Only five studies used different clinical measures or cut-offs to discriminate between dental anxiety, fear and phobia., Conclusion: The dental literature appears unable to capture and also measure the multi-sided construct of dental anxiety, fear and phobia and, therefore, there was a tendency to use them interchangeably.

- Abstract
Introduction: The Full Outline of Unresponsiveness (FOUR) score was developed to compensate for the limitations of Glasgow coma score (GCS) in recent years. This study aimed to assess the predictive value of GCS and FOUR score on the outcome of multiple trauma patients admitted to the emergency department., Patients and Methods: The present prospective cross-sectional study was conducted on multiple trauma patients admitted to the emergency department. GCS and FOUR scores were evaluated at the time of admission and at the sixth and twelfth hours after admission. Then the receiver operating characteristic (ROC) curve, sensitivity, specificity, as well as positive and negative predictive value of GCS and FOUR score were evaluated to predict patients' outcome. Patients' outcome was divided into discharge with and without a medical injury (motor deficit, coma or death)., Results: Finally, 89 patients were studied. Sensitivity and specificity of GCS in predicting adverse outcome (motor deficit, coma or death) were 84.2% and 88.6% at the time of admission, 89.5% and 95.4% at the sixth hour and 89.5% and 91.5% at the twelfth hour, respectively. These values for the FOUR score were 86.9% and 88.4% at the time of admission, 89.5% and 100% at the sixth hour and 89.5% and 94.4% at the twelfth hour, respectively., Conclusion: Findings of this study indicate that the predictive value of FOUR score and GCS on the outcome of multiple trauma patients admitted to the emergency department is similar.

- Abstract
Purpose: The aim of this study was to examine the effect of chlorhexidine disinfection, as a chemical method of oral hygiene practice, and subsequent use of probiotics on halitosis in children. The effects of mechanical and chemical oral hygiene practice methods on the severity of halitosis were also assessed., Materials and Methods: 208 children with organoleptic test (OLT) scores of 2 or more were randomly assigned to four groups: A: conventional oral hygiene practices (COH) including toothbrushing and flossing; B: COH + tongue scraping (TS); C: COH + TS + chlorhexidine; D: COH + TS + chlorhexidine + probiotics. OLT was performed at 1-week and 3-month follow-ups., Results: A significant and stable number of participants showed major and moderate levels of improvement in OLT scores in group D (p < 0.001). The improvement of OLT scores in group C was also significant (p < 0.001), but not stable over the follow-ups (p = 0.44). Neither significant nor stable improvements in the OLT scores were detected in groups A and B through follow-ups (p > 0.05)., Conclusion: Probiotic therapy following oral disinfection with chlorhexidine may reduce the severity of halitosis over longer periods.

- Abstract
Background and aims. Anterior esthetic restoration is challenging in pediatric dentistry, due to limited durability and poor retention of the restoration.This study assessed the effect of air abrasion on tensile failure load of composite class III restorations using different preparation techniques. Materials and methods. 100 extracted human anterior primary teeth were divided, based on the preparation methods, into four groups each consisting of 25 subjects : conventional (A), labial surface bevel (B), conventional + air abrasion (C), and labial surface bevel + air abrasion (D). After restoring cavities, tensile failure load of samples was measured in Newton by Universal testing machine at a crosshead speed of 1 mm per minute. The data were analyzed by Kruskal-Wallis and Mann Whitney U tests using SPSS software. Results. There were statistically significant differences between groups A and C (P = 0.003), groups A and B (P & 0.001), groups A and D (P & 0.001), groups B and C (P = 0.028), groups B and D (P = 0.027), and also groups C and D (P& 0.001). Group D demonstrated the highest mean tensile failure load. Conclusion. Labial surface bevel treated by air abrasion showed significantly more retention of composite restoration.

- Abstract
Pathological changes in pulp and periapical tissues are addressed by endodontic treatment. The material used in this treatment must be biocompatible. The aim of this study is to compare the skin reaction of Calcium Enriched Mixture (CEM) and Mineral Trioxide Aggregate (MTA) produced in Iran on rabbit. Sixteen male newzeland albino rabbits weighting 2 kg were used. The animals back hair was shaved, 24 hours before application of each material. The material was applied on two sites (2 × 2 cm) while the third site was used as control. All sites were covered by gauze and bandaged for 4 hours. Then the material's remnants were washed off the sites of application. Observations were performed in 1, 24, 48 and 72 hours after removing the materials. Erythematous surface areas were measured by the morphometric method. After sacrificing animals the skins were dissected and the specimens were prepared for histological evaluation. There were significant differences between CEM and MTA in erythematous surface areas at 1, 24 and 48 hours after removing the materials (p<0.05). However there was no significant difference at 72 hours after removing the materials. Data showed significant differences in counted cells between MTA and control sample (p=0.0001) and between MTA and CEM (p=0.035). There was no significant difference between control and CEM (p>0.05). The average erythematous surface areas were wider in MTA sites than CEM sites. As a conclusion it seems that biocompatibility of CEM could be more than MTA.

- Abstract
In this in vivo study, the skin reactivity of rabbits to Mineral Trioxide Aggregate (MTA) and Calcium Enriched Mixture (CEM) was compared. Sixteen albino rabbits were used. The dorsal skin in three areas (2 x 2 cm) of the rabbits was shaved 24 h prior to the test. The areas were randomly covered with freshly mixed biomaterials [MTA (n = 16), CEM (n = 16) and normal saline (control; n = 16)], sterile gauze and bandages were placed for 4 h and the biomaterials were washed. The surface areas of the reactive skin sections were examined by naked eye and measured in 1, 24, 48 and 72 h using the Cavalier technique. The animals were then sacrificed and histological sections were prepared for blind examination. Results of macroscopic examination revealed a significant difference (p = 0.003) between the average erythematous surface areas induced by MTA (1.61 +/- 0.32) and CEM (0.5 +/- 0.16). Results of histological examination showed that the highest inflammation was observed in MTA, followed by CEM and control groups. Comparison of the difference in inflammatory cell count between each group revealed statistically significant differences in all cases (p < 0.001). The results demonstrated that the biocompatibility of CEM cement is higher than MTA; CEM can be considered as a suitable endodontic biomaterial.

- Abstract
Purpose: Vitamin D compounds have been shown to inhibit tumor growth in a transgenic retinoblastoma murine model. The mechanism of action has not been defined clearly, although an antiangiogenic action has been proposed., Methods: Transgenic retinoblastoma mice received high (0.05 microgram) and low (0.025 microgram) doses of vitamin D3 by intraperitoneal injection 5 times per week for 5 weeks. Control animals were injected with mineral oil vehicle alone. At 5 months of age, the animals were killed and eyes were enucleated and processed for light microscopy. Paraffin-embedded sections were stained with an immunoperoxidase stain (GS-1) specific for mammalian vascular endothelium. Sections were graded by a single masked reviewer, and intraobserver reliability was assessed. Mean vessel counts were made for each group., Results: The high-dose group had the lowest mean vessel count (8.5), followed by the low-dose group (10.1). The control group had the highest mean vessel count (14.1). Vitamin D-treated animals (high- and low-dose groups combined) had significantly fewer vessels P = 0.001) than untreated controls., Conclusions: These results support the hypothesis that inhibition of angiogenesis is a mechanism of action for vitamin D in the transgenic retinoblastoma mouse model.
