Objective: Triticeous cartilage is a small ovoid structure belonging to the laryngeal skeleton. When calcified, it becomes visible on panoramic radiographs and be mistaken for a carotid artery calcification (CAC) associated with cerebrovascular accidents. This study aimed to estimate the prevalence of calcified triticeous cartilage (CTC) detected by means of digital panoramic radiographs in a sample of Lebanese population. Materials and Methods: Digital panoramic radiographs of 500 Lebanese adult patients (281 females and 219 males) with a mean age of 47.9 years were included in this study and examined for CTC. The IBM® SPSS® for Windows version 20.0 (SPSS, Chicago, IL, USA) was used to carry out statistical analysis of the data collected. Results: Nearly 10.6% (53 out of 500) of the radiographs examined presented CTC. Of all the calcifications, 11 were on the right side, 5 on the left side, and 37 were bilateral. The cases detected belonged to 31 females and 22 males with an average age of 55.6 years (ranging from 24 to 85 years). Chi-square test did not show any statistical connection between gender and CTC, while Spearman's correlation analysis showed low positive correlation with age (r = 0.146). Conclusion: CTC can be detected on panoramic radiographs taken in daily dental practice; its identification is essential to avoid misdiagnosis with other calcifications in the neck region closely related to life-threatening risks such as CAC.

Objective: To estimate the maximum voluntary molar biting force (MBF) and incisor biting force (IBF) and their relationship to morphological variables in subjects with different vertical skeletal patterns. Materials and Methods: Maximum voluntary MBF, IBF, and morphological variables were recorded in 120 subjects (60 males and 60 females) with skeletal class I pattern in the age range of 14 to 24 years. All subjects were divided into 3 groups: Normodivergent, hypodivergent, and hyperdivergent, according to the maxillomandibular plane angle and Jarabak ratio. Bite force measurements were undertaken using a custom-made portable digital gnathodynamometer on the left and the right sides of the jaw in the molar and incisor regions during maximal clenching. Statistical analysis was performed using independent t-test, chi-square test, and ANOVA test using SPSS version 22.0.0.0 software. Results: MBF and IBF are influenced by gender with higher values obtained for male subjects in all groups in the following order: hypodivergent > normodivergent > hyperdivergent. No significant changes were seen with morphological variables in different groups. Conclusion: Molar and incisor biting forces are highest in hypodivergent subjects and least in hyperdivergent subjects as a reflection of jaw morphology and muscular efficiency. In all groups, males exhibit higher force values than females, underlining a strong gender influence on biting force and facial pattern.

Introduction: Psychiatric emergencies constitute between 1% - 10% of general emergencies in Spain, of which a quarter will end up being hospital admissions. There is little literature on patients who are referred from general to specialized hospitals. Methods: Cross-Sectional study of all the patients referred in 2018. Sociodemographic variables and clinical variables, such as diagnosis and discharge destination, were analyzed. An analysis was performed by comparing means with the Chi Square test. Results: 433 derived emergencies were analyzed. Most of the patients were women. The main reason for derivation were suicide attempts. Of those patients, 40% required hospitalizations. More than 50% of the derived emergencies were referred to the home and followed up on an outpatient basis. Conclusion: Most derived emergencies are referred to the home after evaluation. This implies that most are not life-threatening and that with adequate tools for evaluating suicide risk, we could avoid transfers and improve the resolution of these cases.

Objective: To determine the prevalence and distribution of premature eruption and agenesis of premolars in a sample of Turkish children. Study design: A sample of 1715 patients aged 5 to 11 years was selected. Panoramic radiographs were used to assess premature eruption and agenesis of premolars. Developmental stage of erupted premolars was assessed using Demirjian’s method and selecting prematurely erupted premolars on the basis of clinical eruption with a root length less than half of their final expected root lengths. Statistical analysis was performed using chi-square test (p &lt;.05). Results: One hundred fifteen (6.7%) of 1715 patients presented at least one premolar agenesis with no significant sex difference (56 boys, 59 girls). Mandibular second premolars were the most absent teeth. Multiple agenesis of premolars (3.4%) was more common than single agenesis (3.3%). A total of 85 (5.0%) patients (51 boys, 34 girls; no significant sex difference) had at least one prematurely erupted premolar, and maxillary first premolars were most commonly affected. Early erupted premolars were in stage D or E based on Demirjian’s dental formation scale. Conclusions: The prevalence of premature eruption and agenesis of premolars in Turkish children were 5.0% and 6.7%, respectively. Both conditions are not uncommon and may highlight the need for early diagnosis to prevent subsequent clinical problems.

In fingerprint analysis, the determination of hand (right or left) is one of the keys to resolving questions regarding the identity of the donor of the print. It is rare to encounter a complete set of 10-digit fingerprints from the scene of a crime. Although vital and imperative, except for a few studies on whorl patterns, the use of single-digit prints and patterns to ascertain the hand of the donor is scarcely reported in the literature. This research describes a novel approach whereby an analysis of twinned loops was carried out to identify the various parameters that may be helpful in ascertaining the hand of the donor. Bilateral rolled fingerprints from 180 healthy consenting adults belonging to a heterogeneous population of central India were collected. Out of the total of 1800 prints taken, 100 twinned loops (50 on the right hand and 50 on the left hand) were analysed. The following six parameters were considered: the slope of the flow of the apex ridges, the distance between the left delta and the ascending core, the distance between the right delta and the ascending core, mid-core position, the position of the loop and ridge tracing. On applying the chi-square test, the results were found to be statistically significant. Therefore, these parameters were found suitable for the determination of the hand from a single twinned-loop print.

Abstract Background and aims: The incidence of Coronary Artery Disease (CAD) has reached alanning proportions in India. The pathological hall mark of CAD is myocardial ischemia resulting from the atherosclerotic narrowing of coronary arteries. In this era of advanced interventions and cardiac surgery, a thorough knowledge of normal and variant anatomy of coronary arteries is of prime significance and of great use both to the clinicians and anatomists. Materials and methods: One hundred coronary angiograms of patients free of disease were studied in detail in different profiles. The data obtained was quantified according to their frequencies. The relation between the length of left main coronary artery and coronary artery dominance was statistically analyzed using the 'Chi Square test for Trend'. Results: This study highlighted some interesting findings such as the origin of Sino- atrial nodal artery from the second segment of right coronary artery in 3% of cases, double right marginal artery in 4% cases. Other variations such as Mouchet's posterior recurrent interventricular artery, origin of circumflex artery from the right coronary artery and abnormal communication between the terminal parts of right coronary artery and circumflex artery were each noticed in 1 % of cases. Conclusions: Coronary arteries and their branches are prone to variations in their course and morphology. Prior knowledge about this is important for the interpretation of coronary angiograms and surgical myocardial revascularization. The present work on normal and variant pattern of coronary arteries will help in gathering momentum to the already advancing research work in this field.

Purpose. The aim of this investigation was to evaluate clinically the percentage of permanent mandibular first molar teeth with three roots amongst Palestinian population. Patients and Methods. Three hundred twenty-two mandibular first molars from 185 females and 137 males scheduled for root canal treatment at the Dental Center of the Arab American University were examined over a 2-year period. The incidence of a third root revealed by periapical radiographs and the comparison of the occurrence between males and females and between the right and left sides of the mandible were recorded. Statistical Analysis. It was performed using the chi-square test with a significant level set at P<0.05%. Results. Of the 322 treated mandibular first molars, twelve teeth were found to have a third root with an overall incidence being 3.73%. More teeth with a third root were treated on the right side of the mandible compared to the left side. Conclusion. The incidence of a third root in Palestinian population was within the range of previous reports from the Middle East but considerably lower than the percentage from the Far East.

Abstract Clinical-pathological sessions are a good method for solving diagnostic and/or therapeutic problems in patients with hemopathies. In these sessions, errors made during health care given to the patient can be detected. By analyzing how and why these errors are made, we can improve patient care and prevent further mistakes. The objective of this study is to describe 34 errors identified in 874 patients with hemopathies at clinical-pathological meetings in two centers, performed with the aim of solving a diagnostic problem and/or a therapeutic decision or due to a great interest of the case, in two institutions, over 22 years (1982–2004). An intererdisciplinary team of hematology specialists gathered every week at interactive sessions of about 45 minutes each, in both institutions. The methodology of sessions was: a description of the medical history of a patient in a one or two-page report and a revision of the different samples (peripheral blood, bone marrow and lymph node morphology, immunocytochemistry, flow-cytometry, cytogenetic and molecular studies) with the aid of a microscope and a TV monitor. A diagnostic and/or treatment were proposed at the end of the session. Eight-hundred and seventy-four reports were analyzed. All the diagnostics were classified: chronic lymphoproliferatives disorders (445), myeloproliferative and myelodysplastic syndromes (136), acute leukemias (136), other haematological diseases (74), non-haematological diseases (31), without a diagnosis after the meeting (52). We identified diagnostic (D) and therapeutic (T) mistakes and considered as the main causes of the medical error (mistake in the diagnosis and/or treatment): lack of expertise (LE), malpractice (MP), impetuosity (IM), bad logistic support (LS), inexplicable (IN). We divided the 22 years into two decades and each error was classified in one of these two groups. Our own mistakes (OM) and the errors made in other institutions (OI) were identified. A comparison between number of errors made in the first 11 years and the second 11 years was made using a Chi-square test. P&lt;0.05 was considered statistically significant. Thirty-four errors (4 %) were detected, being more D and T (20) rather than only D (14). The type of error detected was: 17 LE, 7 MP, 5 IM, 3 LS, 2 IN. Twenty errors were OM and 14 were made in OI. The difference in the proportion of errors detected during the first and the second decade (6.6 % vs 2.8 %, respectively) was statistically significant (p=0.05). No error led to the death of any patient or were life-threatening in any way. Errors may be made in the diagnosis and treatment of hematologic patients. Although the rate of error found appears to be high, it can be considered as low, since the cases were presented in scientific sessions because of diagnostic and/or therapeutic problems. One of the best ways of improving how to care for future patients is to detect and analyze the errors made. Many lessons can be learnt in this way.

Aims. The aim of this study was to assess the self-perception of dental appearance among Eastern Nepalese patients using aesthetic component (AC) of the index of orthodontic treatment need (IOTN) and to compare it with that of an orthodontist’s assessment using the same scale and determine whether gender, area of residence, and level of education influence subject’s self-perception and orthodontist’s ratings.Methods. A total of 252 subjects (equal number of male and female) were conveniently selected. The average ages of subjects were22.33±2.114years. The level of subject’s perception and orthodontist’s assessment was analyzed by nonparametric Chi square test. Kappa coefficient was done to verify its agreement. The Spearman’s correlation test was used to check the association of educational level and age. Mann-Whitney test was used to check the associations of sex and areas of residence.Results. The demand for treatment was significantly associated with the perception of the subject and orthodontist’s assessment. However, age, gender, and educational level were statistically insignificant in influencing subject perception and orthodontist’s assessment.Conclusion. Patient’s self-perception should be given equal importance while planning orthodontic treatment.

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.
