Evaluation of Timetable of the Second Permanent Molar Calcification among Children between 5 and 17 Years of Age

Objective: This study evaluates timetable of calcification stages of the second permanent molars (SPMs) based on panoramic radiographic findings from a selected group of Iranian patients. Methods: This descriptive, analytical and cross sectional study uses 715 panoramic radiographs of subjects with optimal quality between 5 to 17 years of age (n=60 for each age group) whom were selected from the referrals to the departments of Orthodontics and Pediatric Dentistry of at Tehran University of Medical Sciences, Iran. Patients with systemic diseases or any kind of syndromes were excluded. Calcification stages were determined based on Demirjian's classification. Data were analyzed using generalized estimating equation (GEE). Results: Only 20% of SPMs of 5 year-olds were in their 2nd stage of calcification and the remaining showed higher stages. The mean age of crown completion was around 8.5 years while the mean ages of root completion for the open and closed apices were 13 years and 3 months and 15.5 years, respectively. Also calcification occurred at earlier ages among girls. Conclusion: Timetable of calcification of SPMs is useful to predict the onset of puberty. Demirjian’s classification well matches Iranian population for determining calcification stage of SMPs. Keywords: Permanent Molar, Tooth Calcification, Forensic Dentistry, Iranian Population Key Messages: Mean age at different stages of calcification of the second permanent molars could be effective in forensic dentistry as well as for diagnostic and treatment purposes.

Objective. The present study aimed to assess dental status in 7–12-year-old Lithuanian children and to evaluate the extent and the efficiency of the Pit and Fissure Sealing in Permanent Molars program. Material and methods. This cross-sectional study was performed between September 2007 and May 2008. Children, aged 7–12 years, from secondary schools in five biggest cities of Lithuania were invited for the examination using a cluster random sampling method. The data for the present study were collected following the general principles for basic oral health surveys of the World Health Organization. Results. The prevalence of dental caries was 85.5%, 88.9%, and 70.6% in 7–8-, 9–10-, and 12-year olds, respectively. The prevalence of dental caries in permanent molars increased with age and became as high as 57.7% in 12-year-old children. The data showed that the mean number of sealed teeth depends on the county and ranged from 0.83 (1.31) to 1.45 (1.85) in 7–8-year olds, from 0.95 (1.29) to 2.54 (1.15) in 9–10-year olds, and from 0.26 to 2.13 (1.15) in 12-year olds. Conclusions. The prevalence and incidence of dental caries in 7–12-year-old Lithuanian children are high. Only half of all examined children have at least one sealed molar. The financial resources allocated for the Pit and Fissure Sealing in Permanent Molars program were used insufficiently; therefore, there is a need for systematic measures in order to improve the efficacy of the aforementioned program.

Anthropologic parameters of the spleen are important because many diseases present with reduction or enlargement of the spleen. No data exists about the standard dimensions of the normal spleen in Iranian population. Therefore, the objective of the study was to investigate anthropologic parameters of the spleen in Iranian cadavers. In 2014-2015, this cross sectional study was undertaken from the Razavi Khorasan Province of Iran. Iranian cadavers (n=693, 152 female/541 male) with no history of poisoning, drug or alcohol addiction, no gross abnormality and injury of the spleen were included in the study. The length, width and thickness of spleen were measured using a Vernier caliper. The mean values of the demographic data were age= 40.28 ± 20.97 years; weight = 63.68 ± 17.40 kg; height = 160.03 ± 28.45 cm and BMI = 25.03 ± 20.46 kg/m2. The mean values of the spleen length, width, thickness, notch, weight and index in the cadavers were 11.32 ± 3.10 cm, 8.05 ± 2.35 cm, 20.12 ± 9.21 mm, 0.84 ± 1.35, 123.87 ± 82.46 g, and 2.01 ± 1.40, respectively. Accessory spleen was found in five cadavers. The anthropologic parameters of the spleen showed significant difference between males and females except for index of the spleen. Having standard data on the spleen is useful for radiologists, surgeons, anatomists and anthropologists. The results of the study may provide valuable data in the standardization of the anthropologic parameters of the spleen in the Iranian population.

This study was designed to compare the Intelligence Quotient (IQ) among 3 to 7-year-old strabismic and nonstrabismic children in an Iranian population. In this cross-sectional study, 108 preschool children with equal numbers of strabismic/non-strabismic disorder (age 3-7 years) were randomly selected from exceptional strabismus clinics of Ahvaz and were evaluated with the preschool and primary scale of intelligence versions of Wechsler (WPPSI). In the current study, 108 children were evaluated. In strabismic patients the mean performance, verbal and total IQ were 89.46±19.79 , 89.57±21.57 and 91.54±22.08 respectively.These mean scores in normal children were 91.89±47.53 , 87.56±15.6 and 89.96±17.62consecuently .The results showed that these three different IQ subscales were not significantly different among 3 to 7 years old strabismic and nonstrabismic children ((P>0.05 for all comparisons). There was no significant difference in IQ between two sexes (P>0.05) while Persian tribe children had greater IQ score compared to other tribes (P<0.05). Also, higher paternal educational status of children related to higher IQ score. IQ score was better in combined deviations and was higher in exotropes than esotropes; however, these differences were not statistically significant.(p>0.05) In this evaluation, we did not found a significant negative interference of strabismus on IQ score of preschool children. It can be concluded that paternal educational level and tribe have a significant effect on intelligent quotient, while this is not the case on sex and ocular deviation.

Background: In recent years, age estimation in forensic medicine has become so important. Teeth are used to estimate age as valuable indicators. Objectives: This study aimed to compare Cameriere and Demirjian methods in estimating chronological age (Age) in an Iranian population and to develop a modified Cameriere method. Methods: In this cross-sectional study, we investigated a total of 486 panoramic radiographs of individuals aged 5 - 15 years adopted from two craniofacial radiology centers in Babol, northern Iran, in 2019. The dental age of subjects was assessed by Demirjian (DAge) and Cameriere (CAge) methods and compared with their chronological age. Also, a formula was designed based on the Cameriere method for our studied population, and the results of the original and modified Cameriere (MCAge) methods were compared. Results: The mean ± SD of Age (10.38 ± 2.30) had a significant difference with DAge (10.67 ± 2.33) and CAge (9.77 ± 2.01) (P < 0.001). The modified Cameriere formula was more accurate than Cameriere one, and MCAge was 10.38 ± 2.12, indicating no significant difference with Age (P = 0.993). Conclusions: According to our results, both Demirjian and Cameriere methods were not reliable for age estimation in the Iranian population. However, the modified Cameriere formula had a very high accuracy in estimating the age of the studied population.

Background: The visual evoked potentials (VEP) is a valuable tool to document occult lesions of the central visual channels especially within the optic nerve. Objectives: The purpose of the present study was to observe the findings of first few cases of VEP done in the neurophysiology department of the National Institute of Neurosciences (NINS), Dhaka, Bangladesh. Methodology: This cross-sectional study was conducted in the Department of Neurophysiology at the National Institute of Neurosciences and Hospital, Dhaka, Bangladesh from September 2017 to March 2020. All patients referred to the Neurophysiology Department of NINS for VEP were included. Pattern reversal VEPs were done using standard protocol set by International Federation of Clinical Neurophysiology (IFCN). Results: The mean age of the study population was 30.70 (±12.11) years (6-68 years) with 31 (46.3%) male and 36 (53.7%) female patients. The mean duration of illness was 8.71 (±1.78) months (3 days- 120 months). Most common presenting symptom was blurring of vision (37.3%) and dimness of vision (32.8%). Patterned VEP revealed mixed type (both demyelinating and axonal) of abnormality in most cases [29(43.35)]. The most common clinical diagnosis was multiple sclerosis (29.85%) and optic neuropathy (26.87%). In the clinically suspected cases of multiple sclerosis, optic neuropathy and optic neuritis most of the cases of VEP were abnormal and the p value is 0.04 in optic neuropathy and optic neuritis. Conclusion: The commonest presentation of the patients in this series were blurring of vision and dimness of vision. The most common clinical diagnosis for which VEP was asked for, was optic neuritis and multiple sclerosis. Most abnormalities were of mixed pattern (demyelinating and axonal).

Background: The amniotic fluid is fundamental for proper fetal development and growth. Ultrasound visualization of the amniotic fluid permits both subjective and objective estimates of the amniotic fluid. Objective: The objective of this study was to determine the reference values of normal single deepest pocket (SDP) – upper and lower limits, mean SDP and variation of the SDP with gestational age among Igbo women of South-Eastern Nigeria extraction carrying uncomplicated singleton pregnancy. Methodology: This was a prospective cross sectional study involving 400 women carrying uncomplicated singleton pregnancies and who were sure of the date of the first day of their last menstrual period. The single deepest pocket / maximum vertical pool were determined once at presentation at the hospital.. The study was conducted from January 1st to December 31st 2015. The second author carried out all the scanning. The SDP was obtained. Results: The womens’ mean and median ages were the same at 28 years. The gestational age range of the pregnancies was 14-41 weeks. The mean SDP was 5.8cm, while the 5th and 95th percentiles were 3.3cm and 8.5cm respectively. There was no difference in the mean SDP in both term and preterm. There was irregular but continuous rise of mean SDP to a peak of 6.8cm at gestational age of 39 weeks. In conclusion, the participants had a mean SDP of 5.8cm. There was also a positive correlation between SDP and Gestational age. We therefore recommend a longitudinal study to assess perinatal outcome and abnormal amniotic fluid volume among Igbo women of South-Eastern Nigeria. Key words: Single Deepest Pocket, Uncomplicated Singleton Pregnancy, Igbo Women.

Endoscopic Tympanoplasty

Tympanoplasty is one of the most performed procedures in ENT. The aggressiveness of its microscopic approach has led otologists to adopt the endoscopic approach as a less invasive alternative. The purpose of this work is to appreciate the advantages and disadvantages of this surgical technique. We conducted a prospective descriptive cross-sectional study on 20 interventions within the ENT department of August the 20th 1953 Hospital of Casablanca from April 2019 to June 2019. The average age of operated patients was 36.3 years. Perforations were unilateral in (71%) of the cases with a predominance of the anterior (29%) and subtotal (36%) locations. The tympanoplasties were performed by 3 different senior otologic surgeons, and were left in (57%). The mean operating time was (59.5 min) and the mean anesthesia duration was 75.1 min. Intraoperative vision allowed us to fully visualize the margins of all perforations (100%) and anatomical structures of the middle ear in almost all interventions. The first procedures carried out were filled with difficulties whose management of intraoperative bleeding was the main one in (42.8%) of the cases. (57%) procedures were described as easy. No complication was detected intraoperatively or immediately postoperatively. Endoscopic tympanoplasty has several advantages, including: Minimally invasive approach to the middle ear; panoramic perioperative vision; Gain of operating time; decrease in the duration of anesthesia; Valuable educational tool; postoperative comfort; Decrease in hospital stay and early return to daily activities; Better aesthetic rendering; cost and transportability. However, we also note a number of disadvantages of endoscopic tympanoplasty, particularly: performing the procedure with one hand; difficulty passing through the EAC; 2D vision that alters the perception of depth; management of intraoperative bleeding; fogging; learning curve.

Exudative Pleural Effusion

Pleural effusion is present when there is >15ml of fluid is accumulated in the pleural space. It can be divided into two types; exudative and transudative pleural effusion. Tuberculosis and parapneumonic effusion are the common cause of exudative pleural effusion whereas heart failure accounts for most of the cases of transudative pleural effusion. This study was a hospital based cross sectional study performed at Nepal Medical College during the period of January 2016-December 2016. A total of 50 patients who fulfilled the inclusion criteria were enrolled. Pleural effusion was confirmed by clinical examination and radiology. After confirmation of pleural effusion, pleural fluid was aspirated and was analysed for protein, LDH, cholesterol. The Heffner criteria was compared with Light criteria to classify exudative or transudative pleural effusion. Among 50 patients, 30 were male and 20 were female. The mean age of patient was 45.4±21.85 years. The sensitivity and specificity of using Light criteria to detect the two type of pleural effusion was 100% and 90.9%, whereas using Heffner criteria was 94.87%, 100% respectively(P<0.01). There are variety of causes for development of pleural effusion and no one criteria is definite to differentiate between exudative or transudative effusion. In this study Light criteria was more sensitive whereas Heffner criteria was more specific to classify exudative pleural effusion. Hence a combination of criteria might be useful in case where there is difficulty to identify the cause of pleural effusion.

Background: Radiographic findings related to the cam and pincer variants of femoroacetabular impingement (FAI) include measurements of the alpha angle and lateral center-edge angle (LCEA). The function of these radiographic findings has been put into question because of high heterogeneity in reported studies. Purpose: The aim of this study was 3-fold: (1) to determine the prevalence of cam and pincer variants according to sex and age on anteroposterior (AP) pelvic radiographs from an asymptomatic nonathletic population, (2) to identify the most common radiographic signs of cam- and pincer-type variants, and (3) to determine if there are variations in the prevalence of these radiographic signs according to sex and age. Study Design: Cross-sectional study; Level of evidence, 3. Methods: There were 3 independent observers who retrospectively analyzed the 939 AP pelvic radiographs (1878 hips) of patients aged 18 to 50 years who did not have hip symptoms and who were not professional athletes. The prevalence of the cam and pincer variants according to the alpha angle and LCEA, respectively, and the presence of other radiographic signs commonly associated with these variables were determined in the overall population and by subgroup according to sex and age group (18-30, 31-40, and 41-50 years). Descriptive and inferential statistics were used to analyze the study sample. Results: The mean age of the included population was 31.0 ± 9.2 years, and 68.2% were male. The prevalence of the cam-type variant was 29.7% (558/1878), and that of the pincer-type variant was 24.3% (456/1878). The radiographic signs that were most associated with the cam and pincer variants were a pistol-grip deformity and the crossover sign, respectively. Significant differences ( P < .001) in the prevalence of these variants were identified between men and women in both variants. No differences were observed in the alpha angle or LCEA according to sex or age. Conclusion: Radiographic findings suggestive of FAI had significant variations with respect to sex and age in this study sample. This study provides information to determine the prevalence of these anatomic variants in the general population.

The Mediterranean diet (MedDiet) is considered as a good example of a healthy dietary pattern that has protective effects on obesity. The aim of the present study was to assess the adherence of adults from three Gulf countries (Saudi Arabia, Oman, and Kuwait) to the MedDiet and its association with obesity risk. A cross-sectional study was conducted on 961 men and women (75.7%) aged 20–55 years old. Waist circumference (WC), and hip circumference (HC) were measured waist/hip ratio (WHR) and body mass index (BMI) were calculated. A validated 14-item Questionnaire was used to measure adherence to MedDiet. The mean of the adherence to MedDiet score was 5.9 ± 2.03 for the total sample. An inverse association was observed between the adherence to MedDiet and BMI after adjusting for potential confounders (p = 0.0003 in total participants, and p = 0.001 in women only). A protective effect was seen with a higher adherence to the MedDiet on HC, suggesting that a greater adherence to the MedDiet was associated with a decreased HC (p = 0.04 in total participants, and p = 0.01 in women only). In conclusion, low adherence to the MedDiet among participants from three gulf countries was associated with increased obesity indicators, BMI, and HC.
