Underwater and Scuba Diving Accidents.

The evaluation and care of an injured scuba diver requires an understanding of the different types of underwater activities that may be deemed scuba diving. Such activities may range from the complex (eg, commercial or technical diving) all the way up to basic recreational scuba or snorkeling. A thorough physical examination should be completed as early as possible with a focus on specific areas at risk for injury and etiology, such as a detailed cardiopulmonary, skin, and neurologic examination. Serial reassessments and supportive care are as equally important as consultation with a dive medicine expert, especially one with hyperbaric capabilities.

A socio-technical systems approach of the accident analysis in Indonesian multiple train accident cases: An application of AcciMap methodology.

The number of cases of train accidents in Indonesia continues to be large in the past few years. This paper analyzes train accident cases in Indonesia using a socio-technical system approach accident model called AcciMap, developed by Jens Rasmussen. The source of data comes from train accident investigation reports from 2015 to 2021 published by the National Transportation Safety Committee. This study uses a qualitative approach with thematic analysis to identify contributing factors and their interactions within the reports. Based on the socio-technical system approach, there are roles and contributions from the five levels of the socio-technical railway transportation system in Indonesia that interact with each other in the occurrence of accidents, including the railway regulatory bodies; other organizations; management of railway service company; processes and physical actions by staff; and condition of equipment and environment. This study has shown that the AcciMap methodology can provide a comprehensive view of the problems and their interactions across the socio-technical levels that influence each other in the occurrence of train accidents in Indonesia. The results also suggest that the socio-technical system approach is expected to be applied in the accident investigation process for the related industry to get more comprehensive insights into the accident.

Prevention, social emancipation, and paradigmatic transition: a 40-year interdisciplinary Brazilian trajectory on accidents and disasters. / Prevenção, emancipação social e transição paradigmática: uma trajetória interdisciplinar de 40 anos no Brasil sobre acidentes e desastres.

The article, in the form of an essay, systematizes a 40-year-long professional trajectory of interdisciplinary and socially engaged experiences around the analysis and prevention of accidents and disasters. This study was mainly developed within the scope of research and postgraduate studies in Public Health in Brazil, driven by the sanitarian movement and the construction of Brazilian Unified National Health System (SUS) in its search for democracy and social and health justices. Its empirical basis involved workers' health and environmental surveillance actions organized in networks led by SUS in conjunction with universities, unions, social movements, environmental nongovernmental organizations (NGO), and Public Prosecutors' Offices. Events of greater socio-environmental complexity in sectors such as steel, petrochemicals, mining, agribusiness, and energy forged the search for new epistemic and interdisciplinary references that encompassed two new justices, i.e., environmental and cognitive. This essay systematizes this trajectory of conceptual contributions in three movements from the 1980s to the present day (each corresponding to a socio-political and institutional context) to reflect on paradigmatic transition movements in the analysis and prevention of accidents and disasters from an interdisciplinary perspective. It ends by suggesting abyssal and emancipatory prevention to face different current crises, including environmental, health, democratic, and civilizing ones.

O artigo, na forma de ensaio, sistematiza uma trajetória profissional de experiências interdisciplinares e socialmente engajadas em torno da análise e prevenção de acidentes e desastres nos últimos 40 anos. O trabalho acadêmico se desenvolveu principalmente no âmbito da pesquisa e pós-graduação na saúde pública brasileira impulsionado pelo movimento sanitarista e a construção do Sistema Único de Saúde (SUS) em sua busca por democracia, justiça social e sanitária. A base empírica envolveu ações de vigilância em saúde dos trabalhadores e ambiental organizadas em redes protagonizadas pelo SUS em conjunto com universidades, sindicatos, movimentos sociais, organizações não governamentais (ONG) ambientalistas e Ministérios Públicos. Eventos de maior complexidade socioambiental em setores como siderurgia, petroquímico, mineração, agronegócio e energia forjaram a busca por novos referenciais epistêmicos e interdisciplinares que abarcam duas novas justiças: a ambiental e a cognitiva. Este artigo apresenta essa trajetória de contribuições conceituais em três movimentos a partir da década de 1980 até os dias atuais, cada qual correspondendo a um contexto sociopolítico e institucional, para pensar movimentos de transição paradigmática na análise e prevenção de acidentes e desastres numa perspectiva interdisciplinar. Finaliza-se com a sugestão de prevenção abissal e emancipatória para enfrentar diferentes crises da atualidade, como a ambiental, a sanitária, a democrática e a civilizatória.

Epidemiology and Characteristics of Ankle and Foot Injuries in Electric Scooter-Related Accidents.

Background: The use of electric scooters (e-scooters) continues to increase as a simple, inexpensive means of transport, resulting in a sharp increase in the incidence of scooter-related accidents. No study to date has closely examined the injury extent to the lower leg, joints, and extremities from e-scooter-related accidents. Here, we investigated the epidemiology and injury patterns of such accidents, focusing on injuries to the ankle and foot. Methods: Based on data from a single tertiary hospital's database, the demographics of 563 patients with scooter-associated injuries were analyzed retrospectively. Among the patients, 229 patients who were injured by e-scooter riding were further investigated. Based on the data, the general demographics of whole scooter-associated injuries and the injury characteristics and fracture cases of the lower leg, ankle, and foot were analyzed. Results: During the 4-year study period, the number of patients injured by e-scooters increased every year. Lower extremities were the most common injury site (67.2%) among riders, whereas injuries to the head and neck (64.3%) were more common in riders of non-electric scooters. Among the lower leg, ankle, and foot injuries of riders (52 cases), the ankle joint (53.8%) was the most commonly injured site, followed by the foot (40.4%) and lower leg (21.2%). The fracture group scored significantly higher on the Abbreviated Injury Scale than the non-fracture group (p < 0.001). Among the fracture group (20 cases), ankle fractures (9 cases) were most common, including pronation external rotation type 4 injuries (4 cases) and pilon fractures (2 cases). Five patients (25%) had open fractures, and 12 patients (60%) underwent surgical treatment. Conclusions: The ankle and foot are the most common injury sites in e-scooter-related accidents. Given the high frequency and severity of e-scooter-related ankle and foot injuries, we suggest that more attention be paid to preventing these types of injuries with greater public awareness of the dangers of using e-scooters.

Teen Perspectives on Suicides and Deaths in an Affluent Community: Perfectionism, Protection, and Exclusion.

Clusters of youth suicide and death are tragic for communities and present long-term consequences for the surviving youths. Despite an awareness of community-based patterns in youth suicide, our understanding of the social and community factors behind these events remains poor. While links between poverty and suicide have been well documented, wealthy communities are rarely targeted in suicide research. In response to this gap, we conducted ethnographic research in a wealthy U.S. town that, over a recent 10-year period, witnessed at least four youth suicides and seven more youth accidental deaths. Our interviews (n = 30) explored community values and stressors, interpersonal relationships, and high school experiences on participant perceptions of community deaths. Youth participants characterize their affluent community as having (1) perfectionist standards; (2) permissive and sometimes absent parents; (3) socially competitive and superficial relationships; and (4) a "bubble" that is protective but also exclusionary. Our qualitative findings reveal network influence in teen suicides and accidental deaths in a wealthy community. Greater attention paid to the negative effects of subcultural values and stressors in affluent communities is warranted. Further, our work promotes the value of ethnographic, community-based methodologies for suicidology and treatment.

Acute myocardial infarction due to accidental electrocution ­ A case report of a 26-year-old African male patient.

We report a case of fatal myocardial infarction (MI) after electrocution in a 26-year-old male patient without cardiovascular risk factors. The patient was admitted to the Emergency Department of the University Clinics of Lubumbashi for management of accidental electrocution on a high-voltage power line. The admission ECG showed lesions consistent with myocardial infarction. Despite treatment, the patient died 30 minutes after admission.

Bystander Presence and Response During Accidental and Undetermined Drug Overdose Deaths: Rhode Island, January 1, 2016-December 31, 2021.

With timely intervention from a bystander, drug overdose victims are more likely to survive. To characterize the frequency of bystander presence and identify overdose response barriers, we analyzed data from overdose fatalities occurring in Rhode Island from 2016 to 2021. Overall, about half (n=1,039; 48.7%) of all overdose deaths in Rhode Island had at least one bystander present. Among decedents who had at least one bystander who was unable to respond (n=338), top reasons of non-response were because they were spatially separated (64.8%), failed to recognize the signs of overdose (54.1%), or were unaware the victim was using drugs (40.2%). To promote by- stander presence and address barriers to bystander response during an overdose, intervention strategies should include efforts that reduce solitary drug use and maximize bystander efficacy, including increasing awareness on the dangers of using drugs alone, increasing the availability of naloxone, and education on recognizing signs of overdose.

Seizure, A Shocking Effect of a Lightning Strike on Aerodrome: A Case Report.

Lightning injuries have a high morbidity and mortality because of the electrical effects on the circulatory, respiratory, and central nervous systems. Most lightning-related deaths occur immediately after injury due to fatal arrhythmias or respiratory failure. We describe the case of a patient who experienced a seizure and respiratory distress secondary to a lightning strike and how our team was able to stabilize and transport the patient. Ultimately, in this particular case study, the patient survived with minimal residual neurologic and hemodynamic effects. Based on this clinical vignette, we review the pathophysiology of lightning injuries and the predictive factors of positive outcomes in such unusual accidents.

Factors influencing fire accidents in urban complexes: a combined DEMATEL and ISM study.

Fire outbreaks in urban complexes are a major safety concern worldwide. Therefore, this study aims to examine the critical factors that influence fire accidents and their interaction mechanisms in urban settings. A (software factors, hardware factors, environmental factors, parties and other factors, SHEL) model is developed to identify 15 risk factors in four categories affecting fire incidents in urban complexes. The Decision-making Trial and Evaluation Laboratory method (DEMATEL) and Interpretive Structural Modeling (ISM) are employed to identify the key factors and their interrelationships, using the evaluation metrics of degree of influence, affected degree, centrality, and hierarchical structure. The results show that lack of safety management rules and regulations (S13), poor security awareness (S1), and uncorrected hidden dangers (S11) are the top three critical factors. Based on the hierarchical structure and centrality values, eight critical paths with the highest impact on fires are identified; for instance, Path 39 (comprising, lack of safety management rules and regulations (S13) → lack of fire training and drills (S12) → insufficient security knowledge (S2) → poor security awareness (S1) → poor sense of security responsibility (S3) → uncorrected hidden danger (S11) → inadequate maintenance of fire-fighting facilities (S14) → Accident), which, among all disaster impact paths, has the highest centrality value of 21.8796 (out of a total of 15 factors and total centrality value of 42.9226; Path 39 involves seven factors, but its centrality value accounts for 50.97% of the total). Finally, based on the factor analysis results, suggestions for fire control measures are provided to prevent fire accidents and ensure the safety of people and property.

Reliability in distinguishing murder from accidental event with current forensic criteria in traumatic head injury.

Discovering a body displaying signs of multiple head trauma requires a thorough examination by the forensic pathologist, and a multidisciplinary approach is recommended. However, determining the manner of death is not always possible. We present a case in which the body of a 60-year-old man was discovered lying face down on the floor of his apartment, partially unclothed, surrounded by blood and vomit, and presenting numerous head injuries. The autopsy concluded that the cause of death was a result of post-traumatic brain injury. Nevertheless, applying current criteria made it challenging to ascertain whether the trauma stemmed from an accidental event or an assault.

Chain of events analysis in diving accidents treated by the Royal Netherlands Navy 1966-2023.

Introduction: Diving injuries are influenced by a multitude of factors. Literature analysing the full chain of events in diving accidents influencing the occurrence of diving injuries is limited. A previously published 'chain of events analysis' (CEA) framework consists of five steps that may sequentially lead to a diving fatality. This study applied four of these steps to predominately non-lethal diving injuries and aims to determine the causes of diving injuries sustained by divers treated by the Diving Medical Centre of the Royal Netherlands Navy. Methods: This retrospective cohort study was performed on diving injuries treated by the Diving Medical Centre between 1966 and 2023. Baseline characteristics and information pertinent to all four steps of the reduced CEA model were extracted and recorded in a database. Results: A total of 288 cases met the inclusion criteria. In 111 cases, all four steps of the CEA model could be applied. Predisposing factors were identified in 261 (90%) cases, triggers in 142 (49%), disabling agents in 195 (68%), and 228 (79%) contained a (possible-) disabling condition. The sustained diving injury led to a fatality in seven cases (2%). The most frequent predisposing factor was health conditions (58%). Exertion (19%), primary diver errors (18%), and faulty equipment (17%) were the most frequently identified triggers. The ascent was the most frequent disabling agent (52%). Conclusions: The CEA framework was found to be a valuable tool in this analysis. Health factors present before diving were identified as the most frequent predisposing factors. Arterial gas emboli were the most lethal injury mechanism.

[Study on causative model of acute occupational poisoning accidents based on interpretative structural model-Bayesian network].

Objective: To further study the causes of acute occupational poisoning accidents, and to provide scientific basis and decision support for the prevention of accidents in advance. Methods: From September 2022 to May 2023, the literature was searched and 232 cases of acute occupational poisoning cases occurred from 2013 to 2022 were collected. The causal nodes of the accident were determined according to the expert score, and the interpretative structural model (ISM) was used to construct the correlation model between the causal nodes to obtain the hierarchical relationship between the factors. The influence of each causal node on the occurrence of acute occupational poisoning accidents was studied by using Bayesian network (BN), and the relationship and influence among the causal nodes were analyzed by Netica 5.18 software to establish the pre-prevention model of acute occupational poisoning accidents and identify the key causal factors. Results: A total of 23, 203, and 6 cases of significant, large, and medium acute occupational poisoning accidents were included, of which 179, 29, and 24 cases were asphyxiating gas, irritating gas, and mixed gas, respectively. ISM of acute occupational poisoning accidents divided the causal factors into a 7-layer and 3-level hierarchical structure model. Among them, operation conditions, protective measures, ventilation equipment, hidden trouble investigation, emergency management, illegal operation, equipment and facilities, and blind rescue were the direct causes of the occurrence and expansion of accidents. Warning devices, inspection situation, safety education situation, safety operation procedures, and technology in the production process were indirect influences that lead to the occurrence and expansion of accidents. Safety production responsibility system, enterprise supervision and management and government supervision were the deep-rooted influences. BN reasoning showed that the maximum probability causal chain of acute occupational poisoning accidents was as follows: safety production responsibility system→enterprise supervision and management→safety education and training→protective measures→accident occurrence. The key factors leading to the occurrence of acute occupational poisoning accidents were inadequate protective measures, equipment and facility failures, operational errors, ventilation equipment not being used properly and improper emergency management. Conclusion: In the prevention of acute occupational poisoning accidents, it is necessary to correctly use protective measures, test equipment and facilities before operation, operate according to regulations, ensure the normal use of ventilation equipment, and strengthen emergency management, so as to reduce the incidence of acute occupational poisoning accidents.

ACC and treatment injuries: is it time to rethink injury causation?

In Aotearoa New Zealand, personal injuries resulting from medical treatment are covered under the Accident Compensation Act 2001. However, before victims of medical injury can receive cover and compensation, they must first satisfy several legal tests. Much criticism and legal action have surrounded the interpretation and application of these legal tests, primarily because of its focus lying on injury causation instead of supporting the incapacitated. This article examines the issues present within the current legislative framework for treatment injury coverage and proposes a potential solution to address the underlying problem.

How High Reliability Can Facilitate Clinical, Organizational, and Public Health Responses to Global Ecological Health Risks.

High reliability organizations operate in complex, high-hazard domains for extended periods without serious accidents or catastrophic failures. High reliability can be described as a condition of persistent mindfulness within an organization, coupled with a relentless, assiduous prioritization of adverse event prevention. This article describes ethically and clinically relevant features of high reliability that health care organizations can draw on to anticipate, identify, and respond to global ecological health threats.

Multi-index comprehensive evaluation model for assessing risk to trainees in an emergency rescue training base for building collapse.

Rescues from building collapse accidents present a significant challenge for China's emergency rescue system. However, there are also many risk factors in a training scenario, which have been summarized in this study. A hierarchical indicator system for personnel safety was established, including 12 first-level indicators and 23s-level indicators. Then, an improved Grey-DEMATEL-ISM-MICMAC evaluation model was constructed to evaluate the level of risk. Influencing factor scores were determined according to the responses from the questionnaire survey. The influencing degree, influenced degree, centrality, and causality were identified, and the importance, relevance, and clustering of the various factors were obtained after making quantitative calculations. The results showed that the order of priority for solving the essential issues was safety education (A2), operating standards and proficiency (A10), equipment inspection (A4), equipment warehousing maintenance and records (A21). The solving of safety education was identified to be the most essential priority. The priority control order of direct causes was Scientific design and construction (A5), Potential fixed hazards in the facility (A12), Physical fitness of personnel (A1), Weather influences (A18), and Initiation efficiency of emergency plans (A20), and direct control measures for these five factors could achieve a relatively significant effect.

Emergency department utilisation and treatment for trauma-related presentations of adolescents aged 16-18: a retrospective cross-sectional study.

BACKGROUND: A recent study conducted at our tertiary hospital emergency department (ED) reviewed ED consultations and found that adolescents aged 16-18 years present significantly more often for trauma and psychiatric problems than adults over 18 years. Accidental injuries are one of the greatest health risks for children and adolescents. In view of the increased vulnerability of the adolescent population, this study aimed to further analyse trauma-related presentations in adolescents. METHODS: We conducted a single-centre, retrospective, cross-sectional study of all adolescent trauma patients aged 16 to 18 years presenting to the adult ED at the University Hospital (Inselspital) in Bern, Switzerland, from January 2013 to July 2017. We analysed presentation data as well as inpatient treatment and cost-related data. Data of female and male patients were compared by univariable analysis. A comparison group was formed consisting of 200 randomly chosen patients aged 19-25 years old with the same presentation characteristics. Predictive factors for surgical treatment were obtained by multivariable analysis. RESULTS: The study population included a total of 1,626 adolescent patients aged 16-18 years. The predominant causes for ED presentation were consistent within case and comparison groups for sex and age and were sports accidents, falls and violence. Male patients were more likely to need surgical treatment (OR 1.8 [95% CI: 1.2-2.5], p = 0.001) and consequently inpatient treatment (OR 1.5 [95% CI: 1.1-2.1], p = 0.01), associated with higher costs (median 792 Swiss francs [IQR: 491-1,598]). Other independent risk factors for surgical treatment were violence-related visits (OR 2.1 [95% CI: 1.3-3.5, p = 0.004]) and trauma to the upper extremities (OR 2.02 [95% CI: 1.5-2.8], p < 0.001). Night shift (OR 0.56 [95% CI: 0.37-0.86], 0.008) and walk-in consultations (OR 0.3 [95% CI: 0.2; 0.4, < 0.001] were preventive factors for surgical treatment. CONCLUSIONS: Male adolescents account for the majority of emergency visits and appear to be at higher risk for accidents as well as for surgical treatment and/or inpatient admission due to sports accidents or injuries from violence. We suggest that further preventive measures and recommendations should be implemented and that these should focus on sport activities and injuries from violence.

[Psychological consequences of amputations in work accidents]. / Consecuencias psicológicas de las amputaciones por accidente laboral.

OBJECTIVE: Amputations in work accidents are a phenomenon with a high incidence and peculiar characteristics. The few studies about the effects of amputation are referred to large limbs, and show that, beyond the physical consequences, there are important psychological consequences. The goal of this paper was to show the updated knowledge on the main psychopathological consequences of amputations in work accidents, as well as the variables that can modulate them. METHODS: A non-systematic bibliographic review was carried out, with varied ad hoc searches for the different variables studied. RESULTS: Studies have focused mainly on anxiety and depressive symptoms, post-traumatic stress disorder, and phantom limb pain. Modulating variables whose presence improves the prognosis of these persons have been identified, such as adaptation to daily life, physical exercise, coping strategies, resilience and quality of life. CONCLUSIONS: The different psychological areas reviewed should be considered when attending people who have suffered an amputation in a work accident. Likewise, enhancing the modulating variables whose presence improves the prognosis is an interesting field for professional intervention.

OBJETIVO: Las amputaciones en accidente laboral son un fenómeno con gran incidencia y características peculiares. Los escasos estudios que abordan los efectos de la amputación se refieren a grandes extremidades y muestran que, más allá de las secuelas físicas, existen consecuencias importantes a nivel psicológico. El objetivo de este artículo fue mostrar el conocimiento actualizado sobre las principales consecuencias psicopatológicas de las amputaciones por accidente laboral y de las variables que pueden modularlas. METODOS: Se llevó a cabo una revisión bibliográfica de carácter no sistemático, con búsquedas variadas ad hoc para las distintas variables estudiadas. RESULTADOS: Los estudios se han centrado principalmente en la sintomatología ansiosa y depresiva, el trastorno de estrés postraumático y el dolor del miembro fantasma. También se han identificado variables moduladoras que mejoran el pronóstico: adaptación a la vida cotidiana, ejercicio físico, estrategias de afrontamiento, resiliencia y calidad de vida. CONCLUSIONES: Las distintas áreas psicológicas afectadas revisadas deben considerarse al acompañar a las personas con amputación por accidente laboral. Asimismo, potenciar las variables moduladoras cuya presencia mejora el pronóstico es un campo interesante para la intervención profesional.

Technological prospecting of patents related to monitoring accidents due to falls in hospitals.

OBJECTIVES: to map the production of technologies aimed at monitoring falls in a hospital environment protected by registered patents. METHODS: a technological prospecting of international patents, with a quantitative approach, with search carried out between February and March 2022 in the Derwent Innovations Index database with descriptors fall, hospital, monitoring. RESULTS: 212 patents were found, with the majority filed and published since 2010, by Tran B (9) and Cerner Innovation Inc (9), focused on health technology. Universities were responsible for 13% of deposits. There was a predominance of records from the United States (43.4%), China (21.7%) and Japan (12.3%), in addition to technological strategies classified as devices for the environment (80.7%) and for preventing falls (66.5%) as well as trend towards resources with multiple functionalities in the same technology. CONCLUSIONS: the plurality of functions in the same device reflects the search for optimizing resources and the concern with comprehensive care.

Psychiatric disorders and mortality due to external causes following diagnosis of endometriosis at a young age: a longitudinal register-based cohort study in Finland.

BACKGROUND: Endometriosis diagnosed in adults is associated with increased risk of various psychiatric disorders. However, little is known concerning psychiatric comorbidity and mortality due to external causes associated with endometriosis diagnosed at a young age. OBJECTIVE: This longitudinal cohort study aimed to investigate the link between surgical diagnosis of endometriosis at a young age and subsequent psychiatric disorders and mortality due to external causes. In addition, we compared the occurrence of the most common psychiatric disorders between different sites of surgically confirmed endometriosis (ovarian vs other) because of possible differences in pain manifestations. STUDY DESIGN: We conducted a retrospective register-based cohort study. Altogether 4532 women with surgically confirmed diagnosis of endometriosis before the age of 25 years from 1987 to 2012 were identified from the Finnish Hospital Discharge Register. They were matched with women without surgically diagnosed endometriosis for age and municipality on the index day (n=9014). Women were followed up from the index day until the end of 2019 for the outcomes of interest, which included 9 groups of psychiatric disorders (inpatient episodes since 1987, outpatient episodes since 1998) and death due to external causes, including deaths due to accidents, suicides, and violence (Finnish Register of Causes of Death). Cox proportional hazard models were applied to assess the crude and parity-adjusted hazard ratios and 95% confidence intervals. RESULTS: The cohort's median age was 22.9 years (interquartile range, 21.3-24.1) at the beginning and 42.5 years (36.7-48.3) after a median follow-up time of 20.0 years (14.5-25.7). We observed a higher hazard of depressive, anxiety, and bipolar disorders in women with endometriosis compared with the reference cohort, with depressive and anxiety disorders being the two most common psychiatric disorders. These differences appeared early and remained the same during the entire follow-up, irrespective of whether assessed from the data on inpatient episodes only or the data on both in- and outpatient episodes. The corresponding adjusted hazard ratios were 2.57 (95% confidence interval, 2.11-3.14) and 1.87 (1.65-2.12) for depressive disorders, 2.40 (1.81-3.17) and 2.09 (1.84-2.37) for anxiety disorders, and 1.71 (1.30-2.26) and 1.66 (1.28-2.15) for bipolar disorders, respectively. A higher hazard was observed for nonorganic sleeping disorders for the first 10 years only (3.83; 2.01-7.30) when assessed using the data on both in- and outpatient episodes. When based on inpatient records, a higher hazard for alcohol/drug dependence after 15 years of follow-up (2.07; 1.21-3.54) was observed. The difference in hazard for personality disorders tended to increase during follow-up (<10 years, 2.12 [1.28-3.52]; ≥10 years, 3.08 [1.44-6.57]). Depressive and anxiety disorders occurred more frequently in women with types of endometriosis other than ovarian endometriosis. No difference in deaths due to external causes was observed between the endometriosis and reference cohorts. CONCLUSION: Surgical diagnosis of endometriosis at a young age was associated with increased incidence of several psychiatric disorders. Moreover, within the endometriosis population, psychiatric comorbidity was more common in women with types of endometriosis other than ovarian endometriosis. We speculate that chronic pain is essential in the development of these psychiatric disorders, and that early and effective pain management is important in reducing the risk of psychiatric morbidity in young women. More research concerning the associations and management of endometriosis and associated psychiatric disorders is warranted.
