Importance of Patient History in Artificial Intelligence-Assisted Medical Diagnosis: Comparison Study.

Background: Medical history contributes approximately 80% to a diagnosis, although physical examinations and laboratory investigations increase a physician's confidence in the medical diagnosis. The concept of artificial intelligence (AI) was first proposed more than 70 years ago. Recently, its role in various fields of medicine has grown remarkably. However, no studies have evaluated the importance of patient history in AI-assisted medical diagnosis. Objective: This study explored the contribution of patient history to AI-assisted medical diagnoses and assessed the accuracy of ChatGPT in reaching a clinical diagnosis based on the medical history provided. Methods: Using clinical vignettes of 30 cases identified in The BMJ, we evaluated the accuracy of diagnoses generated by ChatGPT. We compared the diagnoses made by ChatGPT based solely on medical history with the correct diagnoses. We also compared the diagnoses made by ChatGPT after incorporating additional physical examination findings and laboratory data alongside history with the correct diagnoses. Results: ChatGPT accurately diagnosed 76.6% (23/30) of the cases with only the medical history, consistent with previous research targeting physicians. We also found that this rate was 93.3% (28/30) when additional information was included. Conclusions: Although adding additional information improves diagnostic accuracy, patient history remains a significant factor in AI-assisted medical diagnosis. Thus, when using AI in medical diagnosis, it is crucial to include pertinent and correct patient histories for an accurate diagnosis. Our findings emphasize the continued significance of patient history in clinical diagnoses in this age and highlight the need for its integration into AI-assisted medical diagnosis systems.

Frequency and indication of non-musculoskeletal examinations: a cross-sectional survey of Quebec chiropractors.

BACKGROUND: Approximately 1% of low back pain is estimated to be caused by serious systemic diseases, including cancer, infection, or abdominal aortic dissection. This study aimed to determine the frequency of execution of non-MSK physical examination procedures among Quebec chiropractors and to identify the clinical context that prompts them to use these physical examination procedures. METHODS: Cross-sectional survey containing 44 questions administered to a random sample of Quebec chiropractors using a succession of online, postal and phone questionnaires. The 4-part survey questionnaire contained six demographic questions, 28 single-choice questions to determine the frequency of execution of non-MSK physical examination procedures, seven short clinical vignettes for which the respondents had to select the non-MSK examinations that would be required, and two questions inquiring about the proportion of new patients for which participants' felt non-MSK examinations were necessary and whether appropriate assessments were performed. The questionnaire was pilot tested, and feedback received integrated prior to administration. We conducted descriptive statistics, Pearson correlations, and an ANOVA. RESULTS: The survey was completed by 182 chiropractors (response rate: 36.4%). The most commonly non-musculoskeletal examination performed daily were blood pressure (12.1%) and cranial nerves (4.9%). The most common tests never performed were oxygen saturation (68.7%), cardiac auscultation (69.2%), tibio-brachial index (71.4%), breast (86.8%), rectal (96.7%), testicular (95.6%), and vaginal (99.9%) exams. Female chiropractors and Quebec University in Trois-Rivières graduates reported that a significantly higher proportion of their new patients required a non-musculoskeletal physical examination compared to male participants (37.2% vs 28.3%) or Canadian Memorial Chiropractic College graduates (33.9% vs 19.9%). Reason for not performing a physical examination included the belief that another healthcare professional was better positioned to perform and/or interpret the related tests (76.4%). CONCLUSIONS: Vital signs and cranial nerve examinations were the most frequency performed non-musculoskeletal examinations reported by chiropractors. Apart from the genitourinary exam almost never performed, most participants chose non-musculoskeletal examinations deemed appropriate for the patient's presentation.

Prompt diagnosis and appropriate treatment of Japanese spotted fever: A report of three cases.

Background: Japanese Spotted Fever (JSF) is a Spotted Fever Group (SFG) rickettsiosis caused by Rickettsia japonica. More than 300 cases are diagnosed annually in Japan, and the number of reported cases has been increasing. Correct diagnoses depend on the triad of symptoms and signs, including fever, rash, and eschar, which can be seen at the site of vector bites. JSF is not life-threatening if treated appropriately without diagnostic delay but there are some fatal cases every year. This negligence leads to disseminated intravascular coagulation (DIC) and multiple organ failure (MOF), and poor prognoses, consequently. Prompt diagnosis of JSF is difficult when the aforementioned triad of signs and symptoms is not initially present. Case report: This report describes three JSF cases: an 87-year-old woman with fever, shock, pancytopenia, DIC, and MOF; a 79-year-old man with fever and difficulty in movement; and a 78-year-old man with fever, general fatigue, and appetite loss. All patients had a rash and eschar, which led to prompt diagnosis and appropriate treatment immediately. All patients were treated without any complications. Why should an emergency physician be aware of this?: As mentioned above, JFS can be fatal with delayed diagnoses and treatment initiations. The key for a prompt diagnosis is to recognize the triad of symptoms and signs, which are not often present initially, and it makes JSF diagnosis challenging. Repeated comprehensive physical examinations are essential for prompt diagnosis and improve prognosis of JSF.

The effects of mentorship and educational videos on nursing students' physical examination skills: a clinical audit.

BACKGROUND: Poor competence in clinical examination skills among nurses has been reported in practice, and there is a strong consensus that physical examination (PE) education must be improved. However, deficiencies cannot be resolved by theoretical training alone, and new training approaches are required to enable nursing students to perform PE accurately. This study aimed to determine and compare the effect of two new educational methods (mentorship and educational video methods) on the physical examination skills of Iranian nursing students. METHODS: This study was a clinical audit with three group pretest posttest design. Eligible nursing students were recruited through the census method and assigned to three groups (mentorship, educational videos, and control group) using permuted block randomization. Students were taught PE skills in three vital systems through three approaches (mentors, educational videos, and routine educational methods). Data were collected using a two-part instrument consisting of a demographic information questionnaire and a 32-item checklist for assessing the students' skills in examining the respiratory system (10 items), cardiovascular system (13 items), and 12 cranial nerves (9 items). Data were analyzed using SPSS software version 16 and descriptive and analytical statistical tests. RESULTS: At baseline, students in all groups scored less than half of the possible scores in all three systems, and the mean scores of the three groups were not statistically different (P > 0.05). After the intervention, the mean scores of students in the mentorship group increased significantly in all three systems (P < 0.001), whereas the mean scores of students in the educational video group and the control group did not change significantly (P > 0.05). Furthermore, after the intervention, the mean scores of the educational video group and the control group did not significantly differ in any of the three systems (P > 0.05). The ANCOVA showed that with posttest score as the covariate, PE skills in all three systems improved one week after the intervention in the mentor group compared to the control group and the educational video group. However, PE skills in all three systems did not improve one week after the intervention in the educational video group compared to the control group. CONCLUSIONS: The mentorship method is more effective than the educational video and routine methods for teaching PE skills to nursing students. Nursing schools can use the mentor method in training nursing students, and it is recommended to revise the PE lesson unit in the nursing curriculum and exchange it from a purely theoretical-based unit to a mixture of theoretical and clinical-based training. Educational videos alone cannot improve nursing students' PE skills; thus, if educational videos are used to teach clinical skills, it is necessary to hold hands-on sessions to provide feedback to students and correct their mistakes.

Outcome of management based on "1+X" model in a health examination center.

OBJECTIVE: To investigate the effect of management measures based on the "1+X" model in physical examination centers. METHODS: This retrospective study was conducted on 5362 individuals who underwent physical examinations in Heping Hospital Affiliated to Changzhi Medical College from January 1, 2020 to December 31, 2022. These subjects were divided into an observation group (n=2681) and a control group (n=2681) according to the different management measures. Subjects from the control group were given routine management measures, while those from the observation group were given management measures based on the "1+X" model. The scores of negative emotions, waiting time for physical examination, acquisition of health knowledge, satisfaction for the physical examinations, and efficiency and degree of credibility in medical management were evaluated and compared between the two groups. RESULTS: After management, the scores of anxiety and depression in both groups were significantly reduced in contrast to before management, and the two scores were significantly lower in the observation group than those in the control group (P<0.05). The observation group experienced significantly shorter waiting time for routine urination, blood sampling, internal and surgical examinations, and electrocardiogram than the control group (all P<0.001). The acquisition of health knowledge in the observation group was significantly better than that in the control group (P<0.05). The satisfaction rates of the observation group in the terms of service attitude, examination environment, health education, and follow-up services were significantly better than those in the control group (all P<0.05). Moreover, the efficiency and degree of credibility in medical management in the observation group were better than those in the control group. CONCLUSION: The application of management measures based on the "1+X" model has a good effect in our physical examination center. On the one hand, it can significantly reduce the waiting time for various physical examinations and alleviate the negative emotions of physical examinees. On the other hand, it can effectively enhance the overall acquisition of health knowledge, the satisfaction of physical examination, and the efficiency and degree of credibility in medical management. This management model is worthy of clinical promotion and application.

Characteristics of the static muscle stiffness of ankle plantar flexors in individuals with chronic ankle instability.

PURPOSE: Individuals with chronic ankle instability (CAI) have deficits in closed kinetic chain dorsiflexion that may perpetuate injury. Determining the characteristics of muscle stiffness in the plantar flexors of individuals with CAI may help in developing appropriate treatments. We aimed to highlight the characteristics of static muscle stiffness in ankle plantar flexor muscles during the passive dorsiflexion of the ankle joint in individuals with CAI. METHODS: A total of 30 patients were included in the study based on the International Ankle Consortium criteria. The patients were categorized evenly into healthy, coper, and CAI groups (i.e., 10 patients in each group). After measuring the dorsiflexion range of motion (non-weight-bearing/weight-bearing) of the ankle joint, the static muscle stiffness measurements of the medial gastrocnemius, lateral gastrocnemius, soleus, and peroneus longus were obtained. The measurements were performed during the knee joint's extension and 50° flexion and passive dorsiflexion between the range of 40° plantar flexion and 20° dorsiflexion. RESULTS: The dorsiflexion range of motion of the CAI group was significantly smaller than that of the healthy and coper groups in the weight-bearing position. No interaction was observed for muscle stiffness in both the knee flexion and extension positions, and no significant differences were identified among the three groups. The shear modulus of the soleus at 20° ankle dorsiflexion with knee flexion had a significant negative correlation with the weight-bearing range of motion of the ankle. CONCLUSION: The limitation in the weight-bearing dorsiflexion range of motion in CAI was largely due to factors other than the increased elasticity of the ankle plantar flexor muscles.

Estratégias de ensino do raciocínio clínico nos cursos de Medicina do Brasil - revisão integrativa / Teaching strategies for clinical reasoning in Brazilian medical schools - an integrative review

Resumo: Introdução: O raciocínio clínico é considerado uma das principais habilidades que devem ser desenvolvidas pelos estudantes de Medicina, porque permite a elaboração de hipóteses diagnósticas e orienta estratégias investigativas e diagnósticas de forma racional. Embora os educadores tradicionalmente foquem o ensino no modelo hipotético-dedutivo ou analítico, muitos professores de medicina enfrentam no seu dia a dia o desafio de encontrar novas estratégias para ajudar seus estudantes a desenvolver o raciocínio clínico. Objetivo: Este estudo realizou uma revisão integrativa da literatura para identificar as estratégias utilizadas no processo ensino-aprendizagem do raciocínio clínico, nas escolas médicas brasileiras. Método: A metodologia utilizada consistiu em seis etapas: 1. elaboração da pergunta da pesquisa; 2. definição dos critérios de inclusão e exclusão; 3. elenco das informações a serem extraídas; 4. avaliação dos estudos incluídos; 5. interpretação dos resultados; e 6. apresentação da revisão. Resultado: A maioria dos trabalhos apontam que o ensino do raciocínio clínico é realizado por meio de discussões de casos clínicos, de maneira incidental, em diversas disciplinas ou por meio do uso de metodologias ativas, como PBL, TBL e CBL. Apenas três trabalhos apresentados em congressos demonstraram experiências relacionadas à implantação de uma disciplina curricular obrigatória voltada especificamente ao ensino do raciocínio clínico. O ensino do raciocínio clínico é priorizado no internato em relação às fases clínicas e pré-clínicas. Conclusão: Poucos são os estudos que analisam a maneira como se dá o processo ensino-aprendizagem do raciocínio clínico nas escolas médicas brasileiras. Embora mais estudos sejam necessários, podemos verificar a falta de conhecimento teórico sobre raciocínio clínico como uma das principais causas de dificuldade para o desenvolvimento dessa competência pelos estudantes.

Abstract: Introduction: Clinical reasoning is considered one of the main skills that must be developed by medical students, as it allows the establishment of diagnostic hypotheses and directs investigative and diagnostic strategies using a rational approach. Although educators have traditionally focused the teaching method on the analytical model, many medical professors face the challenge in their daily lives of finding new strategies to help their students develop clinical reasoning. Objective: To carry out an integrative literature review to identify the strategies used in the teaching-learning process of clinical reasoning in Brazilian medical schools. Method: The methodology used consists of six steps: 1. creation of the research question; 2. definition of inclusion and exclusion criteria; 3. list of information to be extracted; 4. evaluation of included studies; 5. interpretation of results and 6. presentation of the review. Results: Most studies indicate that the teaching of clinical reasoning is carried out through discussions of clinical cases, incidentally, in different disciplines or through the use of active methodologies such as PBL, TBL and CBL. Only three studies presented at conferences disclosed experiences related to the implementation of a mandatory curricular discipline specifically aimed at teaching clinical reasoning. The teaching of clinical reasoning is prioritized in internships in relation to the clinical and pre-clinical phases. Final considerations: There are few studies that analyze how clinical reasoning is taught to medical students in Brazilian medical schools. Although more studies are needed, we can observe the lack of theoretical knowledge about clinical reasoning as one of the main causes of the students' difficulty in developing clinical reasoning.

[Project to Improve Satisfaction in the Conscription Physical Examinations Service].

BACKGROUND & PROBLEMS: In response to a decrease in satisfaction to 69.3%, we resolved to optimize the process of conducting conscription physical examinations. After an investigatory panel conducted an analysis, the following problems were identified. Firstly, the poorly designed route lead to dense queues between exam stations. Secondly, the procedures for changing the dates of conscription physical examinations were cumbersome. Lastly, unexpected contacts between examinees and the patients in the hospital occurred from time to time, which increases the risk of cross infection. PURPOSE: This project was developed to improve the level of satisfaction in conscription physical examinations and increase the quality of medical services provided. RESOLUTION: After brainstorming and reviewing the related literature, we identified several actions to address and resolve the problems. We adopted non-crossing lines, divided the servicemen's cabins for inspection, simplified the information system process, relocated the physical examination venue, and planned education and training. RESULTS: Satisfaction with the examination process increased from 69.3% to 90.3%. CONCLUSIONS: A survey-based review of the conscription physical examination process should be conducted annually to ensure the procedures are as smooth as possible and to improve the quality of medical services provided.

Basic Public Health Service Utilization by Internal Older Adult Migrants in China.

Since 2009, the Chinese government has launched a basic public health services (BPHS) equalization program to provide the same BPHS to all the citizens. However, utilization of BPHS among older migrants is still low. The purpose of this paper was to explore the determinant individual and contextual factors of older migrants' utilization of BPHS, and to provide suggestion for the government to improve BPHS utilization. Based on Andersen's model of health services use, data from the China's Regional Economic Statistics Yearbook 2014 and National Health and Family Planning Dynamic Monitoring Survey on Migrant Population 2015 were analyzed using a hierarchical random intercept model for binary outcomes. Results showed that the percentage of migrant older adults receiving free physical examinations, which is an important item of BPHS, was 36.2%. Predisposing (education, hukou, living duration in the host city, and scope of migration), enabling (health insurance and social networks), and need (self-rated health and chronic conditions) factors of individuals' characteristics had significant impact on the use of BPHS. The proportions of both migrant children enrolled in public schools and people with established health records had a positive impact on an individual's chance of receiving free physical examinations. These findings suggest that economic development and improvement at the level of the city's health resources cannot effectively improve access to BPHS by older adult migrants. Instead, the driving force appears to be supportive policies for the migrant population.

Assessment of knowledge of junior doctors and non-specialists about musculoskeletal medicine.

OBJECTIVES: To assess the knowledge and confidence of junior doctors and non-specialists in examining and making a diagnosis of patients with musculoskeletal (MSK) diseases. METHODS: This was a Cross-sectional study of 121 doctors working in medical clinics at a tertiary hospital between October and December 2019. Data were collected using a questionnaire. Doctor's awareness regarding different MSK examination methods including gait, arms, leg, spine (GALS), pediatric gait, arms, leg, spine (pGALS) and regional examination of musculoskeletal system (REMS) was noted. Undergraduate teaching of these methods and use in their daily practice was surveyed. RESULTS: Majority of the doctors lacked awareness about different MSK examination techniques. Awareness about GALS, REMS and pGALS was 44.6%, 59.5% and 18.2% respectively. There was significant correlation of GALS/REMS awareness with the undergraduate teaching and doctor's clinical experience (p-value <0.05). Confidence level of doctors in diagnosing patients with adult MSK pathologies was 55%. Only few doctors were satisfied with their musculoskeletal education (29%). CONCLUSION: The GALS examination is a useful screening tool for junior doctors and non-specialists in a direct access setting to rule out musculoskeletal problems.

[The investigation of health outcomes in the German National Cohort: the most relevant endpoints and their assessment]. / Erforschung von Erkrankungen in der NAKO Gesundheitsstudie. Die wichtigsten gesundheitlichen Endpunkte und ihre Erfassung.

The focus of the German National Cohort, the largest population-based cohort study in Germany to date, is the investigation of the most important widespread diseases, such as cardiovascular diseases, diabetes, cancer, neurological and psychiatric disorders, and frequent respiratory and infectious diseases. This cohort will answer questions on the development of these diseases and on the impact of genetic, environmental and lifestyle-related risk factors. Another focus is on the identification of early, subclinical markers of emerging diseases. To answer these questions, a comprehensive assessment of these health outcomes as well as of all potential determinants and precursors is mandatory.This paper describes the various health outcomes that are assessed in the German National Cohort, as well as the examination modules that are applied for deep phenotyping of study participants. Repeated collection of biosamples as well as functional measurements and application of modern imaging techniques at various time points allow for assessing the dynamics of physiological changes related to the individuals' health status. The prognostic value of these changes for disease development will be explored and translated to novel approaches for prevention and personalised medicine. Incident diseases are being assessed through self-reports by study participants and through record linkage with data from health insurances and cancer registries. Additional information about clinical diagnoses is obtained from the treating physicians to ensure the highest possible validity.

Back to Basics: Key Physical Examinations and Theories in Patients with Heart Failure.

Heart failure (HF) is a leading cause of hospitalization. Suitable pharmacologic management is critical. Distinct physical findings such as congestion and peripheral hypoperfusion need to be considered in selecting pharmacologic therapy. By applying the pretest probability and likelihood ratios of unique physical findings of HF to a Markov model, a definite posttest probability can be obtained. This article focuses on the findings of S3, jugular venous pressure, proportional pulse pressure, bendopnea, trepopnea, and various heart murmurs. Incorporating statistical precision in physical assessments, diagnoses of HF can be further refined, providing a sophisticated approach to evaluate patients hemodynamics status noninvasively.

Measuring the palpable pulsatility length as a physical examination test in defining the severity of inflow stenosis for hemodialysis fistulas.

BACKGROUND: Pulsatility is an important property of hemodialysis arteriovenous fistulas (AVF) and can be perceived by the fingers as a gradual decrease in strength downstream from the anastomosis along the main trunk of the fistula. The distance from the point at which the pulse becomes imperceptible to the anastomosis is termed the palpable pulsatility length (PPL); we considered this length may play a role in assessing the severity of inflow stenosis for hemodialysis fistulas. METHODS: This study was performed by retrospective analysis of routinely collected data. Physical examinations and fistula measurements were performed in a selected population of 76 hemodialysis patients with mature fistulas during half a year. Fistula measurements included the PPL before and after treatment and the distance between the anastomosis and the arterial cannulation site (aPump length). The aPump index (API) was calculated by dividing the PPL by the aPump length. Angiograms were reviewed to determine the location and severity of stenosis. PPL and API were used to detect the critical inflow stenosis, which indicates severe inflow stenosis of an AVF. RESULTS: Receiver operating characteristic analysis showed that the area under the curve was 0.895 for API and 0.878 for PPL. A cutoff value of API < 1.29 and PPL < 11.0 cm were selected to detect the critical inflow stenosis. The sensitivity was 96.0% versus 80.0% and specificity was 84.31% versus 84.31% for API and PPL, respectively. CONCLUSIONS: PPL and API are useful tools in defining the severity of pure inflow stenosis for mature AVFs in the hands of trained examiners with high sensitivity and specificity.

Spontaneous Isolated Superior Mesenteric Artery Dissection Requiring Emergent Surgery.

A 52-year-old man with a history of hypertension was referred to our hospital due to persistent abdominal pain. Abdominal palpation revealed remarkable rigidity and rebound tenderness all over the abdomen. Enhanced computed tomography demonstrated the superior mesenteric artery (SMA) dissection with a complete obstruction at the middle part of the SMA. Intraoperative findings showed significant necrosis in the most small intestine and surgical resection was performed. Emergent operation is warranted once abdominal pain becomes uncontrollable or intestinal necrosis is suspected. Physicians should pay careful attention to patients' symptoms and repeatedly perfume physical examinations.

Blurred boundaries: sexuality and power in standardised patients' negotiations of the physical examination.

BACKGROUND: Working with standardised or simulated patients (SPs) is now commonplace in Simulated Learning Environments. Embracing the fact that they are not a homogenous group, some literature suggests expansion of learning with SPs in health professional education by foregrounding their personal experiences. Intimate examination teaching, whether with or without the help of SPs, is protected by a particular degree of ceremony given the degree of potential vulnerability. However, other examinations may be equally intrusive for example the close proximity of an eye examination or a chest examination in a female patient. In this study, we looked at SPs' experiences of boundary crossing in any examinations, sensitised by Foucault's concept of the clinical gaze. We wished to problematise power relations that construct and subject SPs as clinical tools within simulation-based education. METHODS: We collected data from 22 SPs, through five focus groups. Analysis was an iterative process, using thematic analysis. Data collection and reflexive analysis continued iteratively until concepts were fully developed and all theoretical directions explored. RESULTS: Students and SPs construct simulated teaching consultations by negotiating the unequal distribution of power between them. The SPs themselves discussed how they, perhaps unknowingly, acted in accordance with the discourse of the clinical gaze. However, SPs became disempowered when students deviated from the negotiated terms of consent and they used their agency to resist this. The SPs used strong sexual metaphors to express the subjugation they experienced, as discourses of sexuality and gender played out in the Simulated Learning Environment. CONCLUSION: We demonstrate that power dynamics and the clinical gaze can have important consequences within the Simulated Learning Environment. Every physical examination can be potentially 'intimate' and can therefore be underpinned by discourses of sexuality and gendered undertones. In partnership with SPs, simulation-based education should create a teaching space that no longer fosters the discourse of the clinical gaze but facilitates students to learn to reflectively navigate, in the moment, the fine line between touching patients versus touching loved ones, and the blurred boundaries that exist in the gulf between sexual contact and benevolent touch.

Value of digital tomosynthesis for physical examination of chest / 医疗卫生装备

Objective To investigate the significance of digital tomosynthesis (DTS) for suspicions lesions in the physical examination of the chest.Methods Totally 1 000 physical examinees were divided into two groups,with 500 younger ones in one group and the remained 500 ones in the other.The examinees underwent examination with digital X-ray radiography,and then the suspicious cases went through DTS examination to analyze the detection rate of pulmonary positive results.Results There were 110 suspected cases found by digital X-ray radiography,including 8 young ones and 102 old ones.The suspected cases went through DTS examination,and totally 92 nodules were found including 4 ones in the young persons and 88 ones in old persons.CT examination found 89 carcinomatous nodules in the 92 ones.Conclusion DTS examination can detect the lesion of the physical examinee,and lays a foundation for early diagnosis and treatment.

[Proximal rupture of the hamstring tendon : From clinical presentation to diagnosis and therapy]. / Proximale Ruptur der Ischiocruralsehnen : Von der klinischen Präsentation zu Diagnose und Therapie.

Rupture of the proximal tendon enthesis of the hamstring muscle (ICM) accounts for approximately 10% of all injuries of the ICM. It occurs most commonly in athletes and active middle-aged individuals. The complete rupture of all three tendons in active patients is generally seen as an indication for surgical repair of the tendon enthesis; however, the correct diagnosis is often not reached in a timely manner. This can lead to prolonged symptoms with pain, weakness and neuralgia. Operative treatment consists of anchor repair of the tendons resulting in good clinical outcome in several case series. Good knowledge of the anatomy and operative approach are mandatory to avoid complications as well as compliance with a gradual rehabilitation scheme to allow tendon to bone healing. The main aim of this review is to highlight the typical history, clinical presentation and examination technique to reach an immediate clinical diagnosis which should be confirmed with a magnetic resonance imaging (MRI) scan.

Examination criteria and calibration procedures for prevention trials of the Early Childhood Caries Collaborating Centers.

OBJECTIVES: To summarize diagnostic criteria and examiner training and calibration of the National Institute of Dental and Craniofacial Research-funded Early Childhood Caries Collaborating Centers (EC4) and report examiner calibration results from 2010 to 2014. The EC4 at Boston University, University of Colorado, and University of California San Francisco are performing randomized controlled early childhood caries (ECC) prevention trials with caries as the main outcome measure. METHODS: The EC4 with University of Iowa consultants developed standardized tooth and tooth surface status examination criteria for use in field conditions, examiner training materials, and examiner calibration and re-calibration methodologies. Calibration and re-calibration were performed with 1- to 5-year-old children in the San Francisco Mission District in which assessments from each examiner to be calibrated were compared with those from a single gold standard examiner from 2010 to 2014. Cohen's kappa statistic was used to determine inter-examiner agreement. RESULTS: A total of seven examiners were successfully (re)calibrated during that period, examining a total of 231 children. Overall unweighted Cohen's kappas for 10 surface conditions exceeded the criterion of 0.70. However, separate agreement for assessment of noncavitated lesions, as in other studies, was lower. CONCLUSIONS: An experienced multidisciplinary and multi-institutional team was able to develop criteria and training materials to anticipate situations and field conditions the main trials would encounter. Examiners were successfully trained and (re)calibrated.

Self-rated health measurement scale in health check-up / 中华健康管理学杂志

Objective To investigate the application value of the self-rated health measurement scale (SRHMS) in health check-up.Method A total of 8 083 health check-up receivers frow Fujian Province underwent SRHMS self-assessment,and the results of the assessment were analyzed by Chi-square test.Result The results of the survey showed that the total prevalence rate of chronic disease was 57.8％ top five were stomach/duodenum diseases (14.57％),hypertension (11.58％),mammary gland disease (8.04％),abnormal blood lipid (7.16％) and prostate disease (6.54％).The proportion of these five kinds of illness was 43.38％.A positive correlation between the prevalence rate of chronic disease and age was found.The difference of the prevalence rate of chronic diseases between each age group was statistically significant (x2=863.816,P=0.000).Those with family history of chronic diseases accounted for 69.27％ and those with history of present illness accounted for 57.83％ (4 674/8 083).Bodily pain,dietary preferences,refined grain intake,lack of exercise,and alcohol drinking was found in 75.03％,60.15％,54.84％,46.07％ and 41.50％ participants.Conclusion The SRHMS could reflect the chronic disease incidence and unhealthy daily habits.
