Sexual dimorphism in the enamel-dentine junction (EDJ) of permanent canines of European modern humans.

OBJECTIVES: Dental anthropological investigations into sexual dimorphism have conventionally concentrated on evaluating the dimensions and configuration of the enamel cap of canines. However, the morphology of the crown dentine surface can be closely linked to that of the enamel surface. This link can facilitate examination of crown morphology even when the enamel surface is slightly worn. Here, we determine if the morphology of the enamel-dentine junction (EDJ) differs within (maxillary vs. mandibular) and between a sample of male (n = 26) and female (n = 21) contemporary human permanent canines from Europe. METHODS: The morphological data of the EDJ were gathered employing a template comprising 96 landmarks and sliding semilandmarks. Subsequently, the data underwent analysis through form space principal component analysis following Procrustes registration, utilizing standard 3D geometric morphometric techniques. RESULTS: Significant differences in the morphology of the EDJ were observed between the sexes, particularly concerning the overall shape of the crown, the symmetry of the mesial and distal edges, and the development of the distal accessory ridge. CONCLUSIONS: Sex differences in the morphology of the EDJ could relate in part to retention of the canine-premolar honing complex in males. Our results indicate that analyses of the permanent canine EDJ may potentially provide a novel method for estimating the sex of adult and nonadult skeletons.

The Identified Skeletal Collection of the School of Legal Medicine: a contemporary osteological collection housed in Universidad Complutense de Madrid, Spain.

ABSTRA: Osteological collections are an important resource for the development of methods to assist in the study of skeletal remains in archeological and/or forensic contexts. The aim is to describe the current characteristics of the Identified Skeletal Collection of the School of Legal Medicine and its historical context. The Identified Skeletal Collection of the School of Legal Medicine of the Complutense University of Madrid consists of 138 male and 95 female individuals, born between 1880 and 1980 and deceased between 1970 and 2009. The minimum age of the sample is perinatal and the maximum age is 97 years. The collection is an essential tool for forensic research, given that its population characteristics can be extrapolated to those of present-day Spain. Access to this collection offers unique teaching opportunities as well as provides the information necessary to develop various lines of research.

Dentists' Perceptions of Their SARS-CoV-2 Risk and Infection Control Needs.

OBJECTIVE: Rapid worldwide dissemination of SARS-CoV-2 has prompted dental professionals to optimise their infection control procedures. To help identify areas of opportunity for protecting dentists and their patients, the aim of this investigation was to analyse Mexican dentists' early perceptions of their risk of exposure to SARS-CoV-2 and their need for comprehensive infection control education. METHODS: This cross-sectional survey was conducted from May 9 to June 3, 2020, during the social distancing phase in Mexico. The survey adhered to relevant guidelines for ethical research design. The questionnaire was designed with Google Surveys and applied online in Spanish. The questionnaire included items on demographics and clinical specialisation. To obtain time-sensitive perceptions, statements were preceded by "While SARS-CoV-2 circulates in the community and new COVID-19 cases are reported"; responses were collected in a 5-point Likert-type scale. RESULTS: The survey's link received 1524 "clicks." Over 25 days, 996 dentists participated (39% men; 89% working in Mexico and 11% in other Spanish-speaking Latin American countries). Most participants (73%) fully agreed that "Looking after patients will pose a risk for the dentist." Total agreement was more common (P = .0001) amongst dentists in Mexico (76%) than amongst those in other countries (53%). Knowing someone with COVID-19 was more common amongst Mexican dentists (P = .0008). The perceived need for enhanced infection control procedures increased with age (P = .0001). Forty-nine percent totally agreed that they sterilise dental handpieces between patients. One-third expressed total agreement that everyone in their clinic was trained in infection control. CONCLUSIONS: Amongst this nonprobabilistic self-selected sample of dentists, age and country of work influenced their perceptions about occupational exposure to SARS-CoV-2 and infection control needs. This survey revealed areas of opportunity to improve infection control education and training for dental professionals.

Geometric Morphometrics of the human cervical vertebrae: sexual and population variations.

This study aims to carry out the first geometric morphometric analysis of the 3D size and shape of the full series of cervical vertebrae delving into variability related to sex and population background. For this reason, we analyzed the cervical vertebrae of both males and females belonging to Europeans, Africans, and Greenland Inuit. We 3D-scanned a total of 219 cervical vertebrae of males and females of three different modern human populations (European, African, and Inuit). A minimum of 72 landmarks and curve semilandmarks were positioned in each of the 3D vertebral models. Landmark configurations were analyzed following the standards of 3D Geometric Morphometrics to test for size and shape differences related to sex or population variation. Results show that male cervical vertebrae are consistently larger than in females while no regular shape differences are observed between males and females in any of the populations. Sex differences in cervical lordosis are thus not supported at the skeletal level of the 3D shape. On the other hand, there is no evidence for population-specific differences in size while shape does vary considerably, possibly also in relation to eco-geographic factors of overall trunk shape. Cervical vertebrae in cold-adapted Inuit were consistently shorter than in Europeans and Africans. The cervical spine may show a different pattern than the thoracic and lumbar spine, which might be related to stronger integration with the cranium, head mobility, and soft-tissue dependence. Our findings suggest that morpho-functional interpretations of the cervical spine based on vertebral skeletal morphology requires caution.

Balance del asesoramiento médico-legal hospitalario mediante análisis factorial exploratorio / Balance of hospital legal medical counselling through exploratory factor analysis

Introducción: El estudio de los enfoques de la medicina legal ha sido ampliamente afrontado en publicaciones en el ámbito de la justicia. Sin embargo, la temática de los servicios de medicina legal hospitalaria ha sido escasamente abordada en investigaciones; no atendiendo a la importancia que tienen estos servicios para el perfeccionamiento de la gestión del riesgo legal de los sistemas sanitarios. Objetivo: Reconocer la estructura factorial de las prestaciones del servicio de medicina legal en un hospital de alto nivel, entre los demandantes de consulta por problemas derivados de la actividad asistencial del hospital. Material y método: Se realizó un estudio descriptivo transversal con una muestra de 1.213 expedientes abiertos durante los años 2007 y 2017. Se efectuó un análisis factorial exploratorio por extracción de componentes principales con Rotación Varimax. Resultados: La media de expedientes fue de 110,27 por año con una desviación típica de 39,51. El análisis factorial mostró la bidimensionalidad de la utilidad del registro (carta de servicios de medicina legal y fundamento médico-legal de las consultas), con la existencia de dos factores subyacentes que, sumados, explicaron el 68,04% de la varianza total. Conclusiones: Se ha obtenido una estructura factorial simplificada a dos factores con una confiabilidad elevada del cuestionario de registro. Por su naturaleza registral y facilidad de empleo, es aconsejable considerar su utilización en la evaluación de la demanda de asesoramiento al servicio de medicina legal hospitalaria por parte de los diferentes usuarios que acuden por problemas relacionados con las actividades habituales del hospital. (AU)

Introduction: The study of legal medicine approaches has been widely addressed in publications in the field of justice. However, the subject of hospital legal medicine services has been scarcely addressed in research; not attending to the importance of these services for the improvement of the legal risk management of health systems. Objective: To recognize the factorial structure of the benefits of the legal medicine service in a high-level hospital, among those seeking consultation for problems arising from the hospital's healthcare activity. Material and method: A descriptive cross-sectional study was carried out with a sample of 1213 files opened during the years 2007 and 2017. An exploratory factor analysis was performed by extraction of main components with varimax rotation. Results: The average of records was 110.27 per year with a standard deviation of 39.51. The factorial analysis showed the two-dimensionality of the usefulness of the registry (letter of legal medicine services and medical-legal basis of the consultations), with the existence of two underlying factors that, added together, explained 68.04% of the total variance. Conclusions: A simplified factor structure to two factors has been obtained with a high reliability of the registration questionnaire. Due to its registry nature and ease of use, it is advisable to consider its use in evaluating the demand for advice to the hospital legal medicine service by the different users who come for problems related to the usual activities of the hospital.

[Defensive medicine in hospital emergency services.] / Medicina defensiva en los Servicios de Urgencias Hospitalarias.

OBJECTIVE: Hospital emergency services have specific care characteristics that make them more vulnerable to the risk of legal claims. The fact of suffering a legal claim for professional practice is a very traumatic event. The objective of this study was to find out the opinion of the professionals of the hospital emergency services in Spain on the importance of practices associated with defensive medicine. METHODS: Survey of 1,449 professionals from public and private hospital emergency services throughout the national territory was made, in the period between March 13th and April 3rd, 2017. A univariate analysis was performed to identify variables in relation to the practice of defensive medicine, and the determination of the groups of greater association (chi2 test) to evaluate these variables. RESULTS: 96.1% expressed the need to strengthen their medical-legal training. 91.3% of the cases felt more legal pressure and 88.7% declared that they act conditioned by the threat of judicial claim. Regarding patient treatments, 89.8% stated that they perform diagnostic tests that may not be necessary and 63% of professionals stated that they extend the stay of patients in the emergency department. As for the healthcare organization, 88% declared that they do not feel protected by the structure and 79.1% do not felt support from the center's management. CONCLUSIONS: Practices associated with defensive medicine are frequent in our country, with a high proportion of criminal proceedings, and the two main causes are dispensable diagnostic tests and unnecessary prolongation of length of stay.

[Utility of the classification analysis in the typology of the the suicide attempt in a hospital population.] / Utilidad del análisis de clasificación en la tipología del intento de suicidio en una población hospitalaria.

OBJECTIVE: Subjects who attempt suicide are not a homogeneous group. Numerous studies accredit different subtypes of individuals with suicide attempts. One of the main applications of classification analysis is the segmentation and selection of the subject's characteristics. The objective of this study is to identify groups of subjects with a suicide attempt and to discover the relationships between them in the hospital population of an area of the Community of Madrid. METHODS: In a case-control study, the classification tree technique based on the CHAID (Chi-square automatic interaction detector) algorithm, included in the SPSS 23.0 program, was applied to a sample of 201 subjects admitted to a highly complex hospital of Madrid. Impulsiveness, couple conflict, psychiatric history and depression were evaluated. RESULTS: Three subtypes or differentiable profiles of the subject related to the suicide attempt have been obtained, (high profile 144 cases 71.64%, medium 35 cases 17.41% and low 22 cases 10.94% of basic risk patterns) with high application value to the clinical setting. CONCLUSIONS: The typologies found allow us to adapt preventive measures on the suicide attempt and carry out focused clinical interventions of a preventive and predictive nature.

[Evaluation of risk factors for suicide attempt in a hospital clinical population in the Community of Madrid.] / Evaluación de factores de riesgo del intento suicida en población clínica hospitalaria en la Comunidad de Madrid.

OBJECTIVE: Suicide attempts have increased considerably in recent decades. They are multifactorial in nature with preventable biopsychosocial components. Suicide attempt constitutes a vital event that affects the family and socioeconomic systems with important repercussions on public health. It is important to identify and analyze the associated risk factors, so that health professionals can consider them in their clinical practice in order to prevent them. The objective of this study was to identify the risk and protection factors that were associated with suicide attempt in the hospital population of an area of the Community of Madrid. METHODS: An analytical study of paired case-controls of patients who attended the reference hospital in Area 6 of the Community of Madrid during 2016 was carried out. Percentages were calculated and chi-square tests were used to establish an association and calculation of odds ratio with its confidence intervals and for a statistical significance of p≤0.05. RESULTS: An association was identified between the suicide attempts of the following variables: depression, couple conflict, psychiatric history and high anxiety, among others. Influence of insufficient economic income and low educational level was found. Of the 67 cases, 59.7% were female, with a predominance of the age groups 21-30 and 31-40 years with 28.36% in both. 82.2% had low income. 35.8% used drugs. 62.7% had some chronic disease. 59.7% presented high anxiety, 53.7% major depression and 67.1% high impulsivity. CONCLUSIONS: There are psychopathological and personal behavioral factors related to suicide attempts, as well as a high percentage of people who attempt to commit suicide by factors of socio-economic and cultural deprivation.

Un 35,8% consumía drogas. El 62,7% presentaba alguna enfermedad crónica. Presentaron ansiedad elevada un 59,7%, depresión mayor el 53,7% e impulsividad alta el 67,1%. CONCLUSIONES: Existen factores psicopatológicos y personales de conducta relacionados con los intentos de suicidio, así como un alto porcentaje de personas que intentan suicidarse por factores de privación socioeconómica y cultural.

A meta-analytic review for the patella sexual dimorphism assessment / Una revisión meta-analítica para la evaluación del dimorfismo sexual de la patela

Sexual dimorphism is one of the most important ways to identify bone remains in mass disasters. Many of them have been used for this purpose; mainly skull, pelvis and long bones. However, only a few studies using the patella have been done and, to our knowledge, there are no assessments of previous results in the literature. Meta-analysis provides a useful strong tool to test, in a systematic way, the most relevant information about a given research field. The aim of this study is to apply the meta-analytic technique to assess the major studies concerning sexual dimorphism in the patella by measuring classical metric traits: maximum height and maximum width, with different techniques, such as caliper, radiography, tomography and magnetic resonance. The 17 papers found, involving a total sample size higher than 2600 patellae, showed a very high heterogeneity- around 93 % of I2 value, for height and width measurements when all the studies were analyzed together. Homogeneity increased when each study was classified according to the techniques used. In this case, a statistical difference appeared, among the several subgroups of techniques for the two measurements, suggesting the importance of the methodology used. Maximum height and maximum width were all showed to be statistically relevant in distinguishing both sexes.

El dimorfismo sexual es una de las formas más importantes para identificar restos óseos en desastres masivos. Se han utilizado huesos como cráneo, pelvis y huesos largos para la diferenciación sexual. Sin embargo, solo se han realizado unos pocos estudios con la patela y, hasta donde sabemos, no hay evaluaciones de resultados anteriores en la literatura. El meta-análisis proporciona una herramienta sólida y útil para probar, de manera sistemática, la información más relevante sobre un cierto campo de investigación. El objetivo de este estudio consiste en aplicar la técnica metaanalítica para evaluar los principales estudios sobre dimorfismo sexual en la patela midiendo los rasgos métricos clásicos: altura máxima y anchura máxima, con diferentes técnicas: calibre, radiografía, tomografía y resonancia magnética. Los 17 de documentos encontrados, con un tamaño de muestra total superior a 2600 patelas, mostraron una heterogeneidad muy alta, alrededor del 93 % del valor de I2, para mediciones de altura y anchura cuando todos los estudios se analizaron juntos. La homogeneidad aumentó cuando cada estudio se clasificó de acuerdo con las técnicas utilizadas. En este caso, se observó diferencias estadísticas, entre los subgrupos de técnicas para las dos mediciones, lo que sugiere la importancia de la metodología utilizada. La altura máxima y la anchura máxima mostraron ser estadísticamente relevantes para distinguir ambos sexos.

The units that consulted the most were the management team 158 (13%), the Institute for Women's Affairs 144 (11.9%) and the Patient Care Service 116 (9.6%). DISCUSSION AND CONCLUSIONS: The department participates in multiple committees and working groups preparing guidelines, documents and protocols, addressing conflicts, regulatory doubts, training deficiencies, recommending courses of action, and mediating with patients and family members to reduce professional uncertainty

Spanish allele and haplotype database for 32 X-chromosome Insertion-Deletion polymorphisms.

X-chromosome markers have been proved to be decisive both complementing and solving kinship analysis, particularly when autosomal markers are not able to produce adequate likelihood ratios between different hypothesis. On the other hand, Pereira et al., (2012) have demonstrated that 32 Insertion/Deletion (InDel) markers located on the X-Chromosome have a very important power of discrimination in human populations, being a novel tool in the forensic and population fields. So, the aim of the present work was testing the forensic and population genetic efficiency of the 32 X-InDel polymorphisms in the Spanish population, and subsequently build an allele/haplotype frequencies database. To accomplish this objective, a total of 555 samples comprising male individuals from 13 Spanish regions were analysed for the above mentioned 32 X-InDels in two independent laboratories. A pairwise FST analysis was performed in order to understand if the studied Spanish sub-populations present significant differences among them, detecting possible population substructure. Also, linkage disequilibrium analyses were computed to investigate the presence of association between markers in the Spanish population. After Bonferroni correction, the absence of significant differences among the studied regions supports a global Spanish population database. Concerning LD, besides previously reported linked markers MID356-MID357 and MID3690-MID3719-MID2089, we also detected significant association between MID3703-MID3774, even after Bonferroni correction. Finally, after computing allele and haplotype frequencies, forensic efficiency parameters were calculated (PDmales = 99.999976 %; PDfemales = 99.99999999998 %). Mean exclusion chance values for duos were 0.999 and trios 0.99999. These results reinforce the suitability of the 32 X-InDels marker set both in identification and kinship studies.

Eleven Basic Procedures/Practices for Dental Patient Safety.

OBJECTIVES: This study aimed to help alleviate the shortage of reliable information on clinical care issues; the Spanish Observatory of Dental Patient Safety (OESPO) has resorted to the study of legal claims by patients and searched those which produced clinical problems. METHODS: Based on OESPO data, this article proposes 11 basic procedures/practices for dental patient safety to help mitigate most preventable adverse events. RESULTS: The sample of the OESPO is large (415 adverse events studied), but it has the bias of a judicial source. However, the results provide an interesting approach to clinical safety in dentistry. When studying in detail the causes that led to preventable adverse events, it can be seen that most of these (and most severe) events have been caused by a small number of erroneous behaviors. CONCLUSIONS: Most preventable adverse events during the dental health care are produced by a relatively small number of causes. Therefore, a few basic safety procedures can reduce significantly these preventable adverse events.

Dentists Survey on Adverse Events During Their Clinical Training.

BACKGROUND: Adverse events (AEs) begin challenging the safe practice of dentistry early when students start treating patients at dental school. We assessed the frequency with which dentists caused common AEs during their undergraduate clinical training. METHODS: A convenience sample of dentists, graduated from more than 34 dental schools in Mexico and other Spanish speaking countries, answered a confidential, self-administered questionnaire with closed-format questions on common AEs they caused and their active errors that could have led to AEs in the teaching clinics. RESULTS: Of 207 participants, 80% had graduated recently. As undergraduates, 79% caused AEs; 38% admitted to causing one adverse event, 41% to causing two or more, and 36% committed active errors that could have hurt patients. No significant associations between AEs and sex or type of school were observed. CONCLUSIONS: The results indicate that dental students caused AEs or committed errors that placed patients at risk, during their clinical training. PRACTICAL IMPLICATIONS: Dental schools must identify challenges to patient safety at their teaching clinics and introduce risk reduction strategies to protect their patients and foster a safety culture in dental education.

CONCLUSIONS: The typologies found allow us to adapt preventive measures on the suicide attempt and carry out focused clinical interventions of a preventive and predictive nature

Sexual dimorphism of dental tissues in modern human mandibular molars.

OBJECTIVES: Previous studies have revealed that human permanent dental tissue proportions differ significantly between males and females, with females having relatively thicker enamel relative to overall crown area than males. The aims of this study are to investigate sexual dimorphism in permanent mandibular molars and to determine whether such differences can be used to estimate sex in modern humans reliably. MATERIALS AND METHODS: The permanent mandibular molars used in this study (n = 51) originate from 36 individuals of known sex from a Spanish anthropological collection. Eight variables were assessed from two-dimensional (2D) mesial planes of section obtained from microtomographic scans. Binary stepwise logistic regression was then applied to the data. RESULTS: Male molars possess significantly greater quantities of dentine than females, both absolutely and proportionally. Females differed significantly from males by having greater relative enamel thickness. Logistic regression identified the proportion of dentine (relative dentine area [RDA]) as the most important sex discriminator, which can be used to correctly classify specimens with an overall accuracy rate of 74.36%. DISCUSSION: These results confirm that sexual dimorphism in mandibular molar size is a result of males having a greater amount of dentine, both absolutely and proportionally. The findings suggest that 2D measurements of RDA may be useful for sex determination, although further research is required to test the reliability of these predictive techniques across different populations.

Estudio de la transexualidad desde la Clínica Médico Forense de Madrid / A study of transsexuality from Medical Forensic Clinic in Madrid

Introducción: El objetivo de este trabajo es el de comparar los casos de transexualidad peritados en la Clínica Médico Forense de Madrid con los publicados en otras series. Material y métodos: Se trata de un estudio retrospectivo sobre los informes emitidos por médicos forenses adscritos a la Clínica Médico Forense de Madrid, desde el once de enero de 1995 hasta el cuatro de mayo de 2007, recogiendo una serie de datos y realizando un estudio observacional descriptivo y transversal. Resultados: Se han obtenido 52 informes en relación con transexualidad, de los que 29 eran de hombre a mujer (55,76%) y 23 de mujer a hombre (44,23%). Se recoge que la mayoría carecían de alteraciones psicopatológicas (72,4/65,2% hombre/mujer respectivamente), la aparición precoz del sentimiento transexual (86,2/100%), la edad de la cirugía de reasignación (hombres entre 18 y los 41 años de edad; mujeres, entre los 22 y los 43 años de edad), y su proximidad a la solicitud de cambio de inscripción registral. Conclusiones: Destaca la alta incidencia de ausencia de alteraciones psicopatológicas (hemos objetivado estas alteraciones aproximadamente en un tercio de los casos), la precocidad en la aparición del sentimiento transexual y la proximidad entre la cirugía transexual y la solicitud de inscripción registral, condicionado por los requisitos legales del momento. Los resultados obtenidos en nuestro estudio son comparables con otras series, teniendo en cuenta la diferencia de procedimientos empleados

Introduction: The objective of this work is to compare the cases of transsexuality studied in the Forensic Medical Clinic of Madrid with those published in other series. Material and methods: A retrospective, descriptive, cross-sectional, and observational study was carried out by collecting a series of data from the reports issued by forensic doctors attached to the Forensic Medical Clinic of Madrid, from 11 January 1995 to 4 May 2007. Results: A total of 52 reports were obtained in relation to transsexuality, of which 29 were from male to female (55.76%), and 23 from female to male (44.23%). It was noted that the majority lacked psycho-pathological disorders (72.4/65.2% male/female, respectively), the early onset of transsexual sentiment (86.2/100%), the age of re-assignment surgery (male between 18 and 41 years of age; female, between 22 and 43 years old), and its proximity to the application for change of registration. Conclusions: The study emphasises the high incidence of absence of psycho-pathological problems (observed in approximately one-third of the cases), the precociousness in the appearance of the transsexual feeling and the proximity between the surgery and the application for registration, conditioned by the current legal requirements. The results obtained in the present study are compared with other series, taking into account the difference in the procedures used

Modern humans sex estimation through dental tissue patterns of maxillary canines.

OBJECTIVES: Dental tissue proportions of human permanent canines is one of only a few sexually dimorphic features that is present in childhood and maintained in adults, offering the opportunity for this to be used in sex determination. This study assesses dental tissue volumes and surface areas of maxillary permanent canines in a sample of known sex to provide new data and to explore the potential of these variables as reliable sexual estimators. MATERIALS AND METHODS: The teeth studied here derive from 56 individuals (27 females and 29 males) of known sex and age, and of different geographic origins. The teeth were scanned and three-dimensional (3D) measurements (volumes and surface areas) were obtained. In addition, a discriminant function analysis was applied. RESULTS: The results presented here concur with those previously published in relation to both size and dental tissue patterns. Male maxillary canines have a greater dentine component, whereas female enamel is thicker, leading to a difference in dental size in favor of males. Discriminant functions were calculated using these histological variables successfully identifying sex in between 87.5% and 93.75% of the known-sex hold-out sample, with 92.3% correctly assigned when all functions were applied together. DISCUSSION: The present study supports that methods for sex determination based on dental tissue measurements can achieve high allocation accuracies, being especially useful in the case of subadults or when no other appropriate method is available.
