Evaluation of the level of internet addiction and its effects on academic performance among medical and paramedical college students in Iraq

INTRODUCTION: Nowadays a considerable population in the world uses the internet. Unfortunately, despite many interests and its specific advances in communication, the Internet is sentenced to have serious side effects. OBJECTIVE: To detect the percentage of internet addiction and its effect on academic performance among Medical and Paramedical students in some Iraqi universities. METHODS: A cross-sectional study was conducted among 806 medical and paramedical students who were subjected to the online survey which includes demographic information associated with internet usage, and Young's Internet Addiction Test (YIAT) was applied to survey the grade of internet addiction. RESULTS: Results reveal a moderate level of addiction among students without significant variations between genders, high significant relationship (p<0.01) between students concerning their housing area, and strong significant variations (p<0.01) in the time of using the internet, besides strong significant differences (p<0.01) between internet addiction and academic performance. CONCLUSION: Medical and paramedical students practice the internet for diverse activities including learning despite their moderate grade of addiction there are no significant differences between genders. They employ it over 5 h/day, which affects negative tasks on their academic performance.

Lingual supplementation may not be required after articaine buccal infiltration anesthesia for lower molar extraction: a clinical comparative study / La suplementación lingual opcional después de la anestesia por infiltración bucal con articaína para la extracción de molares inferiores: un estudio clínico comparativo

Purpose: To investigate the anesthetic effectiveness of buccal infiltration (BI) versus buccal plus lingual infiltration (BI+LI) of 4% articaine for intra-alveolar extraction of erupted mandibular molar teeth. Material and Methods: Eighty patients were included in this prospective clinical study. They were randomly divided into 1 of 2 equal groups: the 1st group received BI of 4% articaine 1.8 ml and LI of 0.5 ml, while the 2nd group received 4% articaine 1.8 ml BI plus 0.5 ml LI of normal saline. Another 1.8 ml articaine BI was given if initial anesthesia was inadequate. Outcome variables included pain, which was rated by patients at 3 intervals using visual analogue scale, and lingual anesthesia and patients' satisfaction which were measured using 5-score verbal rating scale. Data analyses used were descriptive statistics, t test, χ2 test, and Pearson's correlation coefficient. P-value value less than 0.05 was considered significant. Results: There were 46 females and 34 males and the mean age was 35.3 years. All outcome variables were comparable between the two study groups (p˃0.05). Anesthesia was successful in 78% and 88% of cases in the (BI) and (BI+LI) groups respectively with no significant difference (p=0.2392). The mean articaine volume used was 2.5 ml and 2.87 ml respectively without significant difference (p=0.090). Conclusion: The anesthetic efficacy of (BI) alone and (BI+LI) of 4% articaine was comparable. When given in an adequate dose, articaine (BI) alone could be justified as an anesthetic option for the intra-alveolar extraction of mandibular molar teeth.

Objetivo: Investigar la efectividad anestésica de la infiltración bucal (BI) versus la infiltración bucal más lingual (BI+LI) de articaína al 4% para la extracción intraalveolar de molares mandibulares erupcionados. Material y Métodos: Ochenta pacientes fueron incluidos en este estudio clínico prospectivo. Se dividieron aleatoriamente en 1 de 2 grupos iguales: el primer grupo recibió BI de articaína al 4% 1,8 ml y LI de 0,5 ml, mientras que el segundo grupo recibió articaína al 4% 1,8 ml BI más 0,5 ml LI de solución salina normal. Se administró otro BI de articaína de 1,8 ml si la anestesia inicial era inadecuada. Las variables de resultado incluyeron el dolor, que los pacientes calificaron en 3 intervalos mediante una escala analógica visual, y la anestesia lingual y la satisfacción de los pacientes, que se midieron mediante una escala de calificación verbal de 5 puntos. Los análisis de datos utilizados fueron estadística descriptiva, prueba t, prueba χ2 y coeficiente de correlación de Pearson. Se consideró significativo el valor del valor de pinferior a 0,05. Resultados: Hubo 46 mujeres y 34 hombres y la edad media fue de 35,3 años. Todas las variables de resultado fueron comparables entre los dos grupos de estudio (p=0,05). La anestesia fue exitosa en el 78% y 88% de los casos en los grupos (BI) y (BI+LI) respectivamente sin diferencia significativa (p=0,2392). El volumen medio de articaína utilizado fue de 2,5 ml y 2,87 ml respectivamente sin diferencia significativa (p=0,090). Conclusión: La eficacia anestésica de (BI) solo y (BI+LI) de articaína al 4% fue comparable. Cuando se administra en una dosis adecuada, la articaína (BI) sola podría estar justificada para la extracción intraalveolar de molares mandibulares.

Association of cigarette and water-pipe smoking with increased visceral adiposity, glycemic intolerance and hematological derangement in Iraqi healthy smokers

Abstract The present study aims to investigate the impacts of cigarette smoking (CS) and water-pipe smoking (WPS) on the visceral adiposity index (VAI), hematological characteristics, and glycemic tolerance in Iraqi healthy smokers. A total of 528 healthy males from different locations of Baghdad city were allocated to three groups; nonsmokers (176), cigarette smokers (178), and WP smokers (174). Baseline characteristics, anthropometric and hematological markers and were reported. Glycemic control was evaluated using the glucose tolerance test. The evidence of elevated VAI, disrupted hematological markers, and impaired glucose tolerance was significantly (P<0.001) different compared with non-smokers and related to the duration of smoking. The impacts of WPS seem to be significantly greater than CS in certain parameters (hemoglobin, hematocrit, methemoglobin, and 2-hour glucose tolerance values). In conclusion, CS and WPS negatively impacted body fat distribution, glucose tolerance, and hematological markers. There is a positive association between the rate of smoking and obesity, glycemic intolerance in both groups

Exploring Work Satisfaction and Characteristics of Iraqi Pharmacist Workforce

Abstract The objectives of this study were to describe work characteristics of Iraqi pharmacists, to compare pharmacist job satisfaction between private and public sectors and to assess factors influencing job satisfaction level. This cross-sectional study of pharmacists, their work sites and work satisfactions used an electronic questionnaire that was posted on Facebook pharmacy professional group from June to September 2018. The participants included pharmacists from all 18 Iraqi provinces. We used multiple linear regression to identify predictors of general job satisfaction among 13 pharmacist characteristics. We received 658 usable surveys. Approximately half (47.24%) of respondents indicated dissatisfaction with their primary workplace. Job performance, patient contact, satisfaction with manager, income and expectation satisfactions were significantly related with work satisfaction. Pharmacists working in the private sector had significantly more control over their workplace and higher satisfaction with manager, income and general satisfactions compared to those working in public sector. Pharmacists work in diverse settings across the public healthcare system, community pharmacies, private drug bureaus and academia. About half of them are dissatisfied with their primary workplace. The private sector has more satisfaction rate compared to the public sector. Thus, officials need to improve job environments in the public sector.

Oral carriage of staphylococcus aureus in people with different body mass index / Colonización oral por staphylococcus aureus en personas con diferente índice de masa corporal

Background: The association between obesity and the oral microbiome has received great attention. Objective: This study aimed to determine the association of oral Staphylococcus aureus with different body mass index people. Material and Methods: A total of 155 saliva samples were collected. The individuals were grouped into three categories according to their BMI, normal weight, overweight and obese individuals. A loopful of saliva sample was cultured and incubated at 37°C for 24. Staphylococcus aureus isolates were diagnosed by colony characteristics, morphology, and biochemical tests. Results: The oral carriage rate of Staphylococcus aureus was 61.3% (65.1% females and 56.5% males). The Staphylococcus aureus rate was 68% in married and 60% in single people. The differences of oral carriage rates of Staphylococcus aureus in obese (73.6%) and overweight (85.4%) populations was statistically significant (p<0.0001) compared to the rate in normal weight group (34%). Among males, the highest oral carriage rate of Staphylococcus aureus was in overweight individuals (82.6%). Likewise, in females, the highest rate of salivary Staphylococcus aureus was among the overweight group (88.9%). Regarding marital status, in single people, the differences of Staphylococcus aureus in obese (p=0.0003) and overweight (p<0.0001) people was significantly compared to normal weight people. But, in married people, the differences in Staphylococcus aureus rates among all groups were statistically not significant (p=0.0935). Conclusion: Staphylococcus aureus was significantly related to overweight and obese individuals. The human oral Staphylococcus aureus may play a key role in the manifestation of obesity. The oral microbiota could provide a new target for improving the physical well being of humans.

Antecedentes: la asociación entre la obesidad y el microbioma oral ha recibido gran atención. Objetivo: Este estudio tuvo como objetivo determinar la asociación de Staphylococcus aureus oral en personas con diferentes índices de masa corporal. Material y Métodos: Se recolectaron un total de 155 muestras de saliva. Los individuos fueron agrupados en tres categorías según su indice de masa corporal: normopeso, sobrepeso y obesos. Se cultivó un asa de muestra de saliva y se incubó a 37°C durante 24 horas. Los aislamientos de Staphylococcus aureus se identificaron mediante las características de la colonia, la morfología y las pruebas bioquímicas. Resultados:La tasa de colonización oral por Staphylococcus aureus fue del 61,3% (65,1% mujeres y 56,5% hombres). La tasa de colonización por Staphylococcus aureus fue del 68% en casados y del 60% en solteros. Las diferencias de las tasas de portación oral de Staphylococcus aureus en las poblaciones obesas (73,6%) y con sobrepeso (85,4%) fueron estadísticamente significativas (p<0,0001) en comparación con la tasa en el grupo de peso normal (34.0%). Entre los hombres, la tasa más alta de portadores orales de Staphylococcus aureus fue en individuos con sobrepeso (82,6%). En las mujeres, la tasa más alta de Staphylococcus aureus salival se también se presentó en el grupo con sobrepeso (88,9 %). En cuantal estado civil, en solteros, las diferencias de Staphylococcus aureus en obesos (p=0,0003) y con sobrepeso (p<0,0001) fueron significativas compararadas con normopeso. Pero, en personas casadas, las diferencias en las tasas de Staphylococcus aureus entre todos los grupos no fueron estadísticamente significativas (p=0,0935). Conclusion: Staphylococcus aureus salival se relacionó significativamente en individuos con sobrepeso y obesidad. El Staphylococcus aureus oral humano puede jugar un papel clave en la manifestación de la obesidad. La microbiota oral podría proporcionar una nueva diana para mejorar el estado físico de los humanos

Prevalence of pineal gland and choroid plexus calcification among iraqi patients attending CT scan units / Prevalencia de calcificación de la glándula pineal y del plexo coroideo entre pacientes iraquíes que asisten a las unidades de tomografía computarizada

SUMMARY: Pineal gland calcification is the most common physiological intracranial calcification followed by the choroid plexus calcification. The objective of the study was to determine the prevalence of the pineal gland and choroid plexus calcification among the Iraqi population attending computed tomography scan units in Baghdad, estimate the mean diameters of the pineal gland calcification, and to detect any correlation between these calcifications with age and sex. This multi-centric cross-sectional study examined 485 CT scans of Iraqi patients between the ages of 1 and 100 years attending CT scan units in the period 1 December 2018 to 1 April 2019. Descriptive and inferential statistics were used. The prevalence of pineal gland calcification was found to be 68 % with the 30-39 age group and male sex predominance. It was found to increase after the first decade of life without real consistency. The mean for pineal gland calcification anterior-posterior diameter was 4.55±2.13 and the mean of the right-left diameter was 3.95±1.54. These diameters were found to differ according to sex and age. Choroid plexus calcification was found to have a prevalence of 53.6 %. In most cases, choroid plexus calcification was found bilaterally (77.3 %). There was no difference in sex, but choroid plexus. In conclusion, calcification was noticed to increase gradually according to age. Both pineal gland and choroid plexus calcification have a relatively high prevalence. While pineal gland calcification formation was demonstrated to have a close relation to age and sex, choroid plexus calcification formation was noticed to relate only to age.

RESUMEN: La calcificación de la glándula pineal es la calcificación intracraneal fisiológica más común después de la calcificación del plexo coroideo. El objetivo del estudio fue determinar la prevalencia de calcificación de la glándula pineal y del plexo coroideo entre la población iraquí que asiste a las unidades de tomografía computarizada en Bagdad, estimar los diámetros medios de la calcificación de la glándula pineal y detectar la posible correlación entre estas calcificaciones con la edad y el sexo. Este estudio transversal multicéntrico examinó 485 tomografías computarizadas de pacientes iraquíes entre 1 y 100 años de edad que asistieron a unidades de tomografía computarizada en el período del 1 de diciembre de 2018 al 1 de abril de 2019. Se utilizaron estadísticas descriptivas e inferenciales. Se encontró una prevalencia de calcificación de la glándula pineal del 68 % con predominio del sexo masculino en el grupo de 30 a 39 años. Se observó que aumentaba después de la primera década de vida sin una coherencia real. La media del diámetro anteroposterior de la calcificación de la glándula pineal fue de 4,55 ± 2,13 y la media del DIÁ- METRO derecho-izquierdo fue de 3,95 ± 1,54; estos diámetros difieren según el sexo y la edad. La calcificación del plexo coroideo tiene una prevalencia del 53,6 %. En la mayoría de los casos, la calcificación del plexo coroideo se encontró de forma bilateral (77,3%). No hubo diferencia de sexo, no obstante en el plexo coroideo se observó que la calcificación aumentaba gradualmente según la edad. Tanto la calcificación de la glándula pineal como del plexo coroideo tienen una prevalencia relativamente alta. Si bien se demostró que la formación de calcificación de la glándula pineal está relacionada con la edad y el sexo, se observó que la formación de calcificación del plexo coroideo se relaciona solo con la edad.

A panoramic study of the morphology of mandibular condyle in a sample of population from Basrah City / Estudio panorámico de la morfología del cóndilo mandibular en una muestra de población de la ciudad de Basora

SUMMARY: The study aims to evaluate the morphological variation of mandibular condyle This analysis was composed of 450 digital orthopantomograms taken for routine investigation to assess the morphology of 900 condylar heads. Condylar morphology was classified into four types (oval, bird beak, diamond and crooked finger). Most common occurring shape were evaluated, symmetry of condylar shape and most common combinations of the condylar shapes present in population were assessed. Out of 900 mandibular condyle, type 1(oval) of condyle was the most commonly appearing shape (56 %), followed by type 3 (diamond), type 2(bird beak) and finally type 4 (crooked finger). Symmetry was seen in 74.2 % of the total sample with the oval-oval was the most commonly occurring. Routine use of orthopantomography can assist dentist in assessment of condylar morphology alterations. Oval shape was the most common in all age groups in males and females. More studies on Iraqi population evaluating mandibular condyle are needed to provide standardized values for mandibular anatomical parts.

RESUMEN: El objetivo del presente estudio fue evaluar la variación morfológica del cóndilo mandibular. El análisis se realizó en 450 ortopantomogramas digitales en una investigación de rutina para evaluar la morfología de 900 cabezas condilares. La morfología condilar se clasificó en cuatro tipos (ovalada, pico de pájaro, diamante y dedo torcido). Se evaluó la forma más común de ocurrencia, la simetría de la forma condilar y las combinaciones más comunes en la población. De 900 cóndilos mandibulares, el tipo 1 (ovalado) de cóndilo apareció con mayor frecuencia (56 %), seguido del tipo 3 (diamante), el tipo 2 (pico de pájaro) y finalmente el tipo 4 (dedo torcido). Se observó simetría en el 74,2 % de la muestra total, siendo el óvalo-óvalo el que se presentó con mayor frecuencia. El uso rutinario de la ortopantomografía puede ayudar al dentista a evaluar las alteraciones de la morfología condilar. La forma ovalada fue la más común en todos los grupos etarios en hombres y mujeres. Se necesitan más estudios sobre la población iraquí que evalúen el cóndilo mandibular para proporcionar valores estandarizados para evaluar la anatomía mandibular.

Orofacial space infections, etiology, microbiological susceptibility and surgical management / Infecciones del espacio orofacial, etiología, susceptibilidad microbiológica y manejo quirúrgico

Orofacial infections are considered as one of most common infections and need rapid and adequate treatment as they affect a very delicate region and are associated with serious life-threatening complications. Orofacial infections can be either odontogenic that is with an origin in teeth and associated structures or non-odontogenic, not associated with teeth, can affect facial spaces and spread from one space to another, so a good knowledge about diagnosis and treating these infections is of utmost importance, and can include both non-surgical and surgical treatment. The aim of our study was to determine the most common cause of orofacial infections, the most common bacterial microorganisms and their antibiotic susceptibility. Materials and Methods: A descriptive study was undertaken in the Department of Oral and Maxillofacial Surgery, Al-Shaheed Ghazi Al-Hariry Hospital, Baghdad, Iraq from 1st January to 30th September 2015. This study included 45 patients with different forms of orofacial infections; data regarding age, gender, underlying cause, facial space involvement, presenting signs were collected through history, clinical examination and radiographs, incision and drainage with swab sample for culture and sensitivity test was performed. Results: Patients with orofacial infections showed a female to male ratio of 1.25:1. The mean age was 32.8 years. Most of the patients were in their 4th decade of life (27%). Most infections were odontogenic in origin (62%), the most common facial space involved was submandibular (65%), the most common isolated microorganism was Streptococcus pyogenes (59%), and most patients were treated using an extra-oral surgical approach (78%). Antibiotics to which bacterial isolated showed the most sensitivity were netilmicin, cefoperazone and rifampicin (91%). Pain and limitation of mouth opening gradually decreased in most of patients during the two weeks follow up period. Conclusion: Orofacial infections were more common in females, in the third and fourth decade of life, were odontogenic in origin, were mostly caused by Streptococcus pyogenes, and most isolates were susceptible to netilmicin, cefoperazone and rifampicin. Pain and trismus decreased over two weeks post-treatment.

Las infecciones orofaciales se consideran una de las infecciones más comunes y necesitan un tratamiento rápido y adecuado, ya que afectan una región muy delicada y se asocian con complicaciones graves que amenazan la vida. Las infecciones orofaciales pueden ser odontogénicas que se originan en los dientes y las estructuras asociadas, o no odontogénicas, no asociadas con los dientes, pueden afectar los espacios faciales y propagarse de un espacio a otro, por lo que un buen conocimiento sobre el diagnóstico y el tratamiento de estas infecciones es de suma importancia, y puede incluir tratamiento no quirúrgico y quirúrgico. El objetivo de nuestro estudio fue determinar la causa más común de infecciones orofaciales, los microorganismos bacterianos más comunes y su susceptibilidad a los antibióticos. Material y Métodos: se realizó un estudio descriptivo en el Departamento de Cirugía Oral y Maxilofacial, Hospital Al-Shaheed Ghazi Al-Hariry, Bagdad, Iraq del 1 de enero al 30 de septiembre de 2015. Este estudio incluyó a 45 pacientes con diferentes formas de infecciones orofaciales; Se recopilaron datos sobre edad, sexo, causa subyacente, afectación del espacio facial, signos de presentación a través de la historia, examen clínico y radiografías, incisión y drenaje con muestra de hisopo para cultivo y prueba de sensibilidad. Resultado: Los pacientes con infecciones orofaciales mostraron una relación mujer/hombre de 1.25: 1. La edad media fue de 32,8 años. La mayoría de los pacientes estaban en su cuarta década de vida (27%). La mayoría de las infecciones fueron de origen odontogénico (62%), el espacio facial más común involucrado fue submandibular (65%), el microorganismo aislado más común fue Streptococcus pyogenes (59%), y la mayoría de los pacientes fueron tratados con un abordaje quirúrgico extraoral (78%). Los antibióticos a los que las bacterias aisladas mostraron mayor sensibilidad fueron netilmicina, cefoperazona y rifampicina (91%). El dolor y la limitación de la apertura de la boca disminuyeron gradualmente en la mayoría de los pacientes durante el período de seguimiento de dos semanas. Conclusión:Las infecciones orofaciales fueron más comunes en las mujeres, en la tercera y cuarta década de la vida, fueron de origen odontogénico, fueron causadas principalmente por Streptococcus pyogenes y la mayoría de los aislamientos fueron susceptibles a la netilmicina, cefoperazona y rifampicina. El dolor y el trismo disminuyeron durante las dos semanas posteriores al tratamiento.

Molecular detection and occurrence of equine theileriosis in Arabian horses in Al-Najaf province/Iraq / Detecção molecular e prevalência de teileriose equina em cavalos árabes na província de Al-Najaf/Iraque

This study was designed to detect equine piroplasmosis using the molecular technique in Al-Najaf province during the season that showed an increment in tick activities. Blood samples were collected from 110 horses with more than two signs of piroplasmosis. After DNA extraction, the product was examined by a polymerase chain reaction to amplify 18SrRNA. The results showed that the overall percentage of equine theileriosis was 38.18%. According to gender, the percentage of infection was 43.48% and 29.27% in females and males, respectively. Significant variations appeared between infected horses according to age, and the percentage of infection was 50% and 35.22% in less than 2 years and more than 2 years age, respectively. Moreover, the percentage of infection was 62.5% and 19.35% in animals with and without acariasis, respectively. Significant variations were also seen in equine theileriosis according to geographical areas, and the higher percentage was reported in Hera district (60.87%), while the lowest percentage was in the center of Al-Najaf (21.43%). This difference may be due to different distribution of vector of disease (tick), which may be the availability of the suitable weather that helped in the multiplication of the intermediate vectors. In conclusion, this study proved the variations in the occurrences of equine piroplasmosis according to gender, age, and geographical areas.(AU)

Este estudo foi desenvolvido para detectar piroplasmose equina usando a técnica molecular na província de Al-Najaf durante o período do ano com maior ocorrência de carrapatos. Foram coletadas amostras de sangue de 110 cavalos que apresentaram mais de dois sinais de piroplasmose. Após a extração do DNA, o produto foi examinado por reação em cadeia da polimerase para amplificar o 18SrRNA. Os resultados mostraram que a porcentagem geral de teileriose equina foi de 38, 18%. De acordo com o sexo, o percentual de infecção foi 43,48% e 29,27% no sexo feminino e masculino, respectivamente. Apareceram variações significativas entre os cavalos infectados de acordo com a idade, e a porcentagem de infecção foi 50% e 35,22% em menos de 2 anos e mais de 2 anos, respectivamente. Além disso, as porcentagens de infecção foram 62, 5% e 19, 35% em animais com e sem acariasis, respectivamente. Também foram observadas variações significativas na teileriose dos equídeos, de acordo com as áreas geográficas, e o maior percentual foi relatado no distrito de Hera (60, 87%), enquanto o menor percentual foi no centro de Al-Najaf (21,43%). Essa diferença pode ser devido à distribuição diferente do vetor da doença (carrapato), que pode ser a disponibilidade do clima adequado que ajuda na multiplicação dos vetores intermediários. Em conclusão, este estudo provou as variações nas ocorrências de piroplasmose eqüina de acordo com sexo, idade e áreas geográficas.(AU)

Their fasting insulin hormone, intelectin-1, anti-Mullerian hormone, luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL), estradiol (E2) and testosterones (T) were determined by ELISA methods. BMI, glucose and quantitative insulin sensitivity check index as well as IR was determined by the homeostasis model assessment.RESULTS: A significant changes (P<0.05) were seen in the level of homeostasis model assessment-IR, E2 and T. Levels of anti-Mullerian hormone, LH, LH/FSH ratio and prolactin were significantly (P<0.01) increased and level of intelectin-1 and E2/T ratio were significantly (P<0.01) decreased, while quantitative insulin sensitivity check index level was not significantly different (P>0.05) between the patients (1°PCOS and 2°PCOS) and control groups. On the other hand, our data reported that FSH level was significantly (P<0.05) lower in obese and higher in non-obese patients with PCOS as compared to control group.CONCLUSION: Levels of intelectin-1 and endocrinological hormones have significantly associated with body mass index, IR and physical activity in patients and normal groups and the strategies that can modulate levels of these parameters would improve metabolic disarrangements in women with PCOS.

Patterns of Maxillary Canine Impaction in Iraqi Population

Abstract Objective: To investigate the prevalence of maxillary canine impaction and whether the impacted canine cases have had a potentially good or poor prognosis if interceptive treatment was practiced at earlier ages. Material and Methods: 1755 panoramic radiographs of patients, aged 13 to 60 years, attending the University of Babylon, College of Dentistry for the period from November 2016 to July 2018 were collected and assessed for the presence of impacted maxillary canines. Subsequently, four suggested prognostic factors for each impacted canine were analyzed and recorded. Results: The prevalence of maxillary canine impaction was 119 (6.78%) with 89 unilateral impaction and 30 bilateral impaction resulting in a total of 149 impacted canines. Regarding the gender, impaction was more evident in females 70 than in males 49 with no statistical significant difference. For the side, impaction was more prevalent on the left (77) than on the right (72), also with no statistical difference (p>0.05). Following the analysis of the four prognostic factors, most of the cases, 117 (78.5%) had at least one prognostic factor to be poor. Although 82 (55%) of the cases had at least one prognostic factor to be good, only 4 had all the prognostic factors to be good. Conclusion: Although the cases that had a potentially good prognosis were little (4 cases), interceptive extraction of primary canines would mostly be beneficial for these patients as it will minimize the treatment time, cost and complications.

Mercury Loss From Dental Amalgam Fillings

Abstract Objective: To compare the amount of mercury in new and old dental amalgam restorations. Material and Methods: This study analyzed twenty samples of dental amalgam restorations, dividing into two groups. Group 1 consisted of samples of new dental amalgam restoration (n=10) and group 2 consisted of samples of old dental amalgam restoration (5-years old) (n=10). In each group, the mercury involved in the dental amalgam restoration was calculated using the cloud point extraction (CPE) method. The new dental amalgam restorations are taken from the patients' mouth after condensation and analyzed directly after setting. The old dental amalgam restorations are removed from the patients' mouth, after 5 years of use by the patients, and then they are analyzed. The independent-samples t-test was used to analyze the differences (p<0.05). Results: For new amalgam restorations, the mean of mercury was 0.1281 µg/mL, while for old restorations it was 0.1029 µg/mL. There was a significant difference between the new and old amalgam restorations in the amount of mercury available (p<0.001). Conclusion: There is a significant loss of mercury over a five years period in the patient mouth.

Clinical Evaluation of Pit and Fissure Sealants Placed by Undergraduate Dental Students in 5-15 Years-old Children in Iraq

Abstract Objective: To clinically evaluate the retention and marginal discoloration of pit and fissure sealants applied to primary and permanent teeth. Material and Methods: The study population encompassed of 5-15 years-old children. After consenting, a light-curing sealant was applied to etched pits and fissures of occlusal surfaces of selected sound teeth. The retention rate and marginal discoloration were assessed, 3 months after application of the sealants based on the criteria proposed by Simonsen's criteria (total retention: score 0, partial loss: score 1, and total loss: score 2). Each tooth was considered as an independent sample during analysis. Results: The achieved sample size was 43 children aged 5-15 years (mean age=10.0 years). Therefore, data of 100 teeth from 43 children were used for the final analysis. The percentage of completely retained sealants (59%) was higher than the percentage of partially retained sealants (23%) and completely missing sealants (18%) after 3 months follow up. Out of 100 sealed teeth, 60% were either had marginal discoloration or completely missing. Using the Mann-Whitney test, there was a statistically significant difference (p<0.05) between primary and permanent teeth in terms of retention. However, there was no statistical difference (p>0.05) between upper and lower teeth in terms of retention. Conclusion: The success rate of fissure sealants after 3 months follow-up was satisfactory.

Prevalence of anti-tissue transglutaminase antibodies in patients with irritable bowel syndrome in Duhok city / Prevalência de anticorpos antitransglutaminase tecidual em pacientes com síndrome do intestino irritável na cidade de Duhok

Abstract Background Irritable bowel syndrome (IBS) is a common gastrointestinal disorder; celiac disease is an autoimmune enteropathy that can mimic any functional gastrointestinal disorder. The aim of this study is to estimate the prevalence of celiac disease antibodies (anti Tissue Transglutaminase-tTG) in patients with irritable bowel syndrome. Patients and methods This cross sectional study was conducted on 70 patients with irritable bowel syndrome fulfilling Rome III criteria who visited Azadi Teaching Hospital in Duhok city-Iraq. Patients were classified according to irritable bowel syndrome subtypes into: Diarrhoea Predominant (D-IBS), Constipation Predominant (C-IBS) and Mixed (M-IBS). IgA and IgG anti tTG were used to screen patients for celiac disease. Results A total number of 70 patients (44 females and 26 males) were included; their mean age was 33 years (SD ± 7.64). Five patients (7.1%) were found to have positive both IgA and IgG anti tTG. Three of them have had D-IBS and the other two had C-IBS. No one of the M-IBS patients tested positive. Conclusion The prevalence of anti tTG antibodies in irritable bowel syndrome is high. Patients with D-IBS should be screened for celiac disease.

Prevalence of impacted mandibular third molars and its association with distal caries in mandibular second molars using cone beam computed tomography / Prevalencia de terceros molares mandibulares impactados y su asociación con caries distales en segundos molares mandibulares mediante tomografía computarizada de haz cónico

This study evaluated the prevalence and eruption's pattern of impacted mandibular third molars (IMTM) and the influence of their eruption status on the distal caries of mandibular second molars (MSM) using cone-beam computed tomography (CBCT). Material and methods: CBCT images taken for different purposes in private dental practices were analyzed retrospectively. Radiographic assessment included: prevalence of IMTM, degree of angulation, level of impaction and type of IMTM. Furthermore, the distance between the cement-enamel junctions (CEJ) of second and third molars and the occurrence of caries lesion on the distal surface of MSM was also evaluated. Data were analyzed by chi square test and logistic regression was used to find the association between distal caries of MSM and eruption status of IMTM. Results: Three hundred and eight CBCTs were screened, the prevalence of IMTM was 36.88% and their angulation degree were mostly less than 90º (mesioangular). Amongst those with impaction, 58 subjects (43%) had distal caries on MSM, 29.6% in females and 30.4% in the age group 19-27 years. Caries on the distal side of MSM were significantly associated with age, level and type of impaction, angulation degree and CEJ distances (p<0.05). Conclusions: The prevalence of IMTM is high (36.88%) and there are significant relationships between angulation degree, level and type of impaction, and CEJ distances with caries on the distal side of MSM.

Introducción: Este estudio evaluó la prevalencia y el patrón de erupción de terceros molares mandibulares impactados (TMMI), y la influencia de su estado de erupción en la caries distal de los segundos molares mandibulares (SMM) mediante tomografía computarizada de haz cónico (TCHC). Material y métodos: se analizaron retrospectivamente las imágenes de TCHC tomadas para diferentes fines en prácticas dentales privadas. La evaluación radiográfica incluyó: prevalencia de TMMI, grado de angulación, nivel de impacto y tipo de TMMI. Además, también se evaluó la distancia entre la unión amelocementaria (UAC) de los segundos y terceros molares y la aparición de lesión de caries en la superficie distal de SMM. Los datos se analizaron mediante la prueba de chi cuadrado y se usó la regresión logística para evaluar asociaciones entre la caries distal de SMM y el estado de erupción de TMMI. Resultados: Se examinaron 308 TCHC, la prevalencia de TMMI fue de 36.88% y su grado de angulación fue mayoritariamente menor a 90º (mesioangular). Entre aquellos con impacto, 58 sujetos (43%) tenían caries distales en los SMM, 29.6% eran mujeres y 30.4% pertenecieron al grupo de edad de 19-27 años. Las caries en el lado distal de MSM se asociaron significativamente con la edad, el nivel y el tipo de impactación, el grado de angulación y las distancias UAC (p<0.05). Conclusiones: la prevalencia de TMMI es alta (36.88%) y existen relaciones significativas entre el grado de angulación, el nivel y el tipo de impacto, y las distancias UAC con presencia de caries en el lado distal de los SMM.

Microcytosis in children and adolescents with the sickle cell trait in Basra, Iraq

BACKGROUND: Microcytic anemia, the most common form of anemia in children and adolescents, is a heterogeneous group of diseases that is acquired or inherited. We assessed the frequency and causes of microcytosis in children and adolescents with the sickle cell trait (SCT). METHODS: This descriptive study included 95 subjects (49 males and 46 females) with SCT who attended Basra Center for Hereditary Blood Diseases for evaluation. Investigations included complete blood count, high performance liquid chromatography, capillary electrophoresis, and measurement of serum ferritin and transferrin levels. RESULTS: SCT subjects had a low hemoglobin (Hb) concentration (9.79±1.75 g/dL), low mean corpuscular volume (MCV, 67.43±9.22), low mean corpuscular Hb (21.15±3.64), and a normal red cell distribution width (RDW, 14.00±2.30). Among 95 SCT subjects, 81 (85.26%) had microcytosis, 12 (12.63%) had normal MCV, and 2 (2.11%) exhibited macrocytosis. Sixty-three (77.78%) SCT subjects with microcytosis were iron deficient, and 18 (22.22%) had normal iron levels. The mean serum ferritin and HbA2 levels were significantly lower, while the RDW, sickle Hb, and serum transferrin levels were significantly higher in patients with microcytosis and iron deficiency compared to non-iron deficient subjects (P0.05). CONCLUSION: Despite the frequent occurrence of iron deficiency in SCT subjects, co-inheritance of alpha-thalassemia seemed to be the cause of low MCV in non-iron deficient individuals with microcytosis. Genetic analysis is required to understand the genetic basis of this phenomenon.
