SUMMARY The COVID-19 pandemic forced the school of medicines to opt for a virtual teaching modality due to the suspension of face-to-face activities imposed by the lockdown. Objective To determine the advantages and disadvantages of the virtual teaching modality perceived by the students in an introduction to clinical medicine course of a school of medicine in Lima, Peru. Methods A virtual non-validated survey was circulated among fourth year medical students. Results 94 studentes answered the survey (51%). Perceived advantages were to have more time to study (57.4%) and saving time in transportation (39.4%). The disadvantages were lack of contact with real patients (42.6%) and not to be able to obtain a clinical history from patients (39.4%). The 72.3% of students were able to identify the medical problems of patients, but only 24.4% were able to obtain an adequate clinical history and just 9.6% performed an adequate physical examination. Conclusion The virtual teaching modality allowed the student to have more time for self-study but limited their abilities to obtain a clinical history and to perform a physical examination.

Quality of Life After Diagnosis of Neurally Mediated Reflex Syncope by Tilt Test

Abstract Background: Vasovagal syncope (VVS) results in impaired quality of life (QoL). The response during the head-up tilt test (HUTT) influences QoL and recurrence. Objectives: To analyze the influence of the type of HUTT response on QoL in patients with VVS and recurrence of events after the exam. Methods: The SF-36 and Impact of Syncope on Quality of Life (ISQL) questionnaires were applied over 12 months after the HUTT. Unpaired Student's t test was used for differences between 2 groups of quantitative data with normal distribution. The recurrence of syncope episodes was analyzed using a Kaplan-Meier curve, and the log-rank test was applied to compare the curves regarding responses to the HUTT. Statistical significance was set at p value < 0.05. Results: We analyzed 82 patients (43.7 years old), 69% with previous recurrence (2.8 prior episodes). Cardioinhibitory response occurred in 46 patients; vasodepressor response occurred in 36, and 85.4% of patients received non-pharmacological treatment after the HUTT. During clinical follow-up, 43.9% had recurrence, mainly young patients (35.7 years; p = 0.002). On the SF-36, the best score was in functional capacity in men (p = 0.04) and patients without prior trauma (p = 0.001). There were lower limitations due to pain in patients without prior trauma (p = 0.003) and patients without prodromes (p = 0.009). On the ISQL, there were better mean scores in men (p = 0.002) and in patients without prior trauma (p = 0.02). Patients with cardioinhibitory response had better SF-36 and ISQL scores (p < 0.001). There was greater VVS recurrence in the cardioinhibitory response group (log-rank p = 0.011; hazard ratio: 8.48; 95% confidence interval: 7.59 to 9.3) from the second to the fourth month, with stabilization in the eighth month after the HUTT, when compared to patients with vasodepressor response. Conclusion: The majority of patients with VVS reproduced during the HUTT under non-pharmacological treatment did not report worsening of QoL during clinical follow-up. Worse QoL was observed in non-young patients and in patients with vasodepressor response, and it was not influenced by recurrence after the HUTT.

Exame físico em ginecologia / Physical examination in gynecology

O exame físico na prática ginecológica diuturna é o sustentáculo de uma perspectiva diagnóstica com vistas a uma abordagem individualizada, oportuna e humanizada da paciente. Lança mão de técnica semiótica clássica, inicialmente, após avaliação de sinais vitais, minuciosa inspeção ectoscópica, seguida de exame físico especial. E deverá ser realizado em ambiente adequadíssimo, sem nenhuma improvisação e ou adaptações não compatíveis, com a importância e a segurança garantidas por um exame físico de boa qualidade. O exame físico de mamas tem como objetivo primordial a identificação de nódulos mamários e, eventualmente, de tumores localmente avançados; e relativa tranquilidade é assegurada às pacientes quando ele é considerado normal. O exame físico vulvar permite a identificação de prolapso de órgãos pélvicos, neoplasia intraepitelial e/ou invasiva vulvar e distúrbios de desenvolvimento sexual, além de oferecer subsídios para a propedêutica da vulvodínea, sendo, principalmente, uma oportunidade para o diagnóstico em dermatologia vulvar, mesmo a vulva correspondendo a apenas 1% da pele feminina. O exame especular, um clássico da ginecologia, é indispensável para a triagem do câncer de colo uterino. Por fim, o toque genital, a despeito de sua subjetividade, permite a avaliação dos órgãos genitais internos.

Physical examination in daytime gynecological practice is the mainstay of a diagnostic perspective with a view to an individualized, timely and humanized approach to the patient; resorting to the classical semiotic technique, initially, after assessing vital signs, a thorough ectoscopic inspection, followed by a special physical examination; which should be carried out in a very suitable environment, without any improvisation or adaptations that are not compatible with the importance and safety guaranteed by a good quality physical examination. The primary objective of the physical examination of the breasts is to identify breast nodules and possibly locally advanced tumors; in addition to relative tranquility, assured to patients, when the respective exam is considered normal. Vulvar physical examination allows the identification of pelvic organ prolapse; vulvar intraepithelial and/or invasive neoplasia; sexual development disorders; in addition to offering subsidies for the propaedeutics of vulvodynia; and, above all, it is an opportunity for diagnosis in vulvar dermatology, even though the vulva accounts for only 1% of female skin. Specular examination, a classic in gynecology, is essential for screening for cervical cancer. Finally, the genital touch which, despite its subjectivity, allows the evaluation of the internal genital organs.

Pesquisa activa de cáncer de mama en mujeres de un Consultorio Médico de la Familia

Introducción: El cáncer de mama constituye en la actualidad un problema de salud pública, tanto en América Latina como a nivel mundial, por su frecuencia y aumento progresivo en el número de mujeres que lo padecen. Objetivo: Identificar la morbilidad oculta por cáncer de mama y sus factores de riesgo en la población femenina de 30 años y más en el Consultorio Médico de la Familia No. 6 del Policlínico Camilo Torres Restrepo. Métodos: Se realizó un estudio descriptivo transversal para identificar algunos factores de riesgo del cáncer de mama en la población femenina perteneciente al Consultorio Médico de la Familia N° 6, del Policlínico Docente Camilo Torres Restrepo, de enero a diciembre del 2022. La población de estudio estuvo conformada por las 131 mujeres de 30 años y más, las cuales fueron pesquisadas a través de entrevista y examen físico de las mamas. Para el análisis de los datos se emplearon números absolutos y porcentajes como medidas de resumen. Resultados: El sedentarismo, la obesidad/sobrepeso y el tabaquismo, fueron los factores de riesgo de mayor prevalencia con el 41,2 % y 29,8 % respectivamente. El 53,4 % de las mujeres manifestaron no realizarse el autoexamen de mama. El 94,7 % de las mujeres presentaron examen físico negativo y un 5,3 % fue dudoso. Conclusiones: Factores de riesgos relacionados con los estilos de vida como el sedentarismo, la obesidad/sobrepeso y el tabaquismo, fueron los factores de riesgo más frecuentes. A pesar de la mayoría de las mujeres presentar examen físico negativo, la no realización del autoexamen de mama, pudiera contribuir al aumento de la morbilidad por esta enfermedad en la población de estudio.

Introduction: Breast cancer is currently a public health problem both in Latin America and worldwide, due to its frequency and progressive increase in the number of women who suffer from it. Objective: To identify hidden morbidity due to breast cancer and its risk factors in the female population aged 30 years and over in medical office No. 6, of the Camilo Torres Restrepo Polyclinic. Methods: A descriptive cross-sectional study was carried out to identify some risk factors for breast cancer in the female population belonging to the Family Medical Office No. 6, of the Camilo Torres Restrepo Teaching Polyclinic, from January to December 2022. The population of the study was comprised of 131 women aged 30 and over, who were screened through an interview and physical examination of the breasts. For data analysis, absolutes numbers and percentages were used as summary measures. Results: Sedentary lifestyle, obesity/overweight and smoking, were the most frequent risk factors with 41.2% and 29.8% respectively. 53.4% of women stated that they did not perform breast self-examination. 94.7% of the women had a negative physical examination and 5.3% were doubtful. Conclusions: Risk factors related to lifestyles such as a sedentary lifestyle, obesity/overweight and smoking were the most representative risk factors. Despite the fact that most women present a negative physical examination, not performing a breast self-examination could contribute to an increase in morbidity from this disease in the study population.

Cognitive abilities and medical students' practice of physical exams: A quasi-experimental study

ABSTRACT BACKGROUND: To highlight the importance of clinical simulations and simulated laboratories for student training, especially in physical examination teaching. OBJECTIVE: To evaluate the gains obtained by medical students in their cognitive and practical performance of physical examinations (abdominal, cardiological, and pulmonary), as well as satisfaction and self-confidence in what they have learned, after concentrated practice developed in a skills and simulation laboratory. DESIGN AND SETTING: A quantitative and quasi-experimental study in which 48 students were evaluated at the Faculdade de Odontologia de Bauru, São Paulo, Brazil. METHODS: A quantitative and descriptive study was conducted with regularly enrolled 2nd year medical students over 18 years of age who had content prior to data collection regarding anamnesis and physical examination remotely taught in a Moodle virtual learning environment. For data collection, the participants were subjected to a concentrated period of skill training (abdominal, cardiological, and pulmonary). Every day after the skill training session, they were subjected to a practical evaluation and completed a theoretical test before and after the practical activities. At the end of all activities, they answered the instrument to assess the simulated practices (self-confidence and satisfaction). RESULTS: Among the 49 students evaluated, positive and significant theoretical and practical gains were identified in all three components (abdominal, cardiological, and pulmonary) (P = 0.000), as well as in the general evaluation (Theoretical 1 and Theoretical 2) (P = 0.000), satisfaction, and self-confidence (P = 0.000). CONCLUSION: Concentrated laboratory practice resulted in positive improvements in students' physical examination skills.

Agreement and reproducibility of a portable electrical impedance myography device for body fat percentage estimation in normal weight men and women / Concordância e reprodutibilidade de um dispositivo portátil de miografia por impedância elétrica para estimativa do percentual de gordura corporal em homens e mulheres com peso normal

Abstract The aim of this study was to investigate the agreement and reproducibility of a portable electrical impedance myography device (EIM - SKULPT®) for body fat percentage (BF%) estimation in young adults. Sixty young adults volunteered for the study (women, n=30, 25.0±7.7 years; 21.5±1.9 kg/m2; and men, n=30, 21.6±6.3 years; 22.5±1.8 kg/m2). Participants underwent air displacement plethysmography (ADP) and EIM measurements for agreement analysis. EIM was performed three times on the same day for the within-day reproducibility analysis. Seven days later, 37 participants repeated the EIM measurements for the between-days reproducibility analysis. Comparisons of EIM and ADP methods, and EIM repeated measurements were performed with the paired T-test or one-way ANOVA repeated measures, the Bland-Altman plot, and simple linear regressions. BF% was higher (p<0.05) when estimated by EIM (19.91 ± 5.70 for men, and 30.77 ± 5.89 for women) compared to ADP (15.28 ± 5.66 for men, and 27.31 ± 5.98 for women). The Bland-Altman analysis presented a bias of 4.4% (95%CI=-3.4-12.2) and linear regression presented an R2=0.78. For between-days reproducibility, EIM means did not differ (25.33±7.69 and 24.94±8.30, p=0.890). Thus, while the EIM device exhibited high reproducibility of BF% estimates, caution should be exercised when comparing the results with other techniques for measuring BF%. The EIM device overestimated BF% compared to ADP. However, the EIM measurements presented very good within-day and between-days reproducibility and, thus, the EIM device can be used for longitudinal monitoring of BF%.

Resumo O objetivo deste estudo foi investigar a concordância e a reprodutibilidade de um aparelho portátil de miografia por impedância elétrica (EIM - SKULPT®) para estimativa do percentual de gordura corporal (GC%) em adultos jovens. Sessenta adultos jovens foram voluntários para o estudo (mulheres, n=30, 25,0±7,7 anos; 21,5±1,9 kg/m2; e homens, n=30, 21,6±6,3 anos; 22,5±1,8 kg/m2). Os participantes fizeram medições de pletismografia de deslocamento de ar (ADP) e EIM para análise de concordância. A EIM foi realizada três vezes no mesmo dia para a análise de reprodutibilidade dentro do dia. Sete dias depois, 37 participantes repetiram as medições do EIM para a análise de reprodutibilidade entre dias. As comparações dos métodos EIM e ADP e medições repetidas do EIM foram realizadas com o teste T pareado ou medidas repetidas ANOVA de uma via, o gráfico de Bland-Altman e regressões lineares simples. O %GC foi maior (p<0,05) quando estimado pelo EIM (19,91 ± 5,70 para homens e 30,77 ± 5,89 para mulheres) em relação ao ADP (15,28 ± 5,66 para homens e 27,31 ± 5,98 para mulheres). A análise de Bland-Altman apresentou viés de 4,4% (IC95%=-3,4-12,2) e a regressão linear apresentou R2=0,78. Para a reprodutibilidade entre dias, as médias do EIM não diferiram (25,33±7,69 e 24,94±8,30, p=0,890). Assim, enquanto o dispositivo EIM exibiu alta reprodutibilidade das estimativas de %GC, deve-se ter cautela ao comparar os resultados com outras técnicas para medir %GC. O dispositivo EIM superestimou %GC em comparação com ADP. No entanto, as medidas de EIM apresentaram reprodutibilidade intradia e entre dias muito boa e, portanto, o dispositivo de EIM pode ser usado para monitoramento longitudinal de %GC.

Conclusion The use of direct visual validation increases the probability of hits by students in cervical dilation assessment in dilation simulators.

Cardiovascular physical examination as a screening tool for congenital heart disease in newborns at a teaching hospital in Ghana

Objectives: To determine the usefulness of cardiovascular physical examination (CPE) as a screening tool in a lowresource setting for detecting congenital heart disease (CHD) in newborns delivered at the Maternity Unit of Korle Bu Teaching Hospital (KBTH), Accra, Ghana. Design: A hospital-based cross-sectional study with a comparison group component. Setting: Maternity Unit of the KBTH, Accra, Ghana. Participants: Over eight months, newborns aged 1-14 days delivered at ≥ 34 weeks' gestation at the Maternity Unit, KBTH, were recruited into the study. Intervention: Each newborn was examined using a set of CPE parameters for the presence of congenital heart disease. Those with suggestive features of CHD had a confirmatory echocardiogram test. Main Outcome Measure: Abnormal CPE features and their corresponding echocardiogram findings. Results: A total of 1607 were screened, with 52 newborns showing signs of CHD on CPE, of which 20 newborns were proven on echocardiogram to have congenital heart disease. Abnormal CPE parameter that was associated with CHD was murmur (P=0.001), dysmorphism (p=0.01), newborns with chest recessions (p=0.01) and lethargy (p=0.02). CPE's sensitivity, specificity, and positive and negative predictive values were 95%, 60.7%, 36.5% and 98,1%, respectively. The most common acyanotic CHD found was isolated atrial septal defect (ASD), followed by patent ductus arteriosus (PDA). The only cyanotic CHD found was a case of tricuspid atresia. Conclusion: Cardiovascular physical examination at birth is an effective and inexpensive screening tool for detecting CHD in newborns, which can easily be utilised in low-resource settings.

Objective:To investigate the correlation between Helicobacter pylori ( H.pylori) infection and albuminuria inphysical examination population. Methods:It was a cross-sectional study. All the adults who received physical examination and underwent 13C-urea breath test at the Physical Examination Center in Tongji Hospital in 2021 were selected as the study subjects. General data (such as demographic information and past medical history) were documented. The physical measurement and blood biochemical indicators were checked too. Multivariate analysis was used to analyze the relationship between H. pylori infection and albuminuria. Results:A total of 30 311 subjects were included in this analysis. There were 17 123 males and 13 188 females with an age of (44.51±12.17) years. The positive rate of H. pylori infection was 27.3%. The incidence of albuminuria in subjects with H. pylori infection was 6.7%, and it was 6.1% in the subjects without H. pylori infection ( P=0.031). After adjusting for the confounding factors such as gender, age, diabetes and hypertension, H. pylori infection was independently associated with the risk of albuminuria (odds ratio ( OR)=1.133, 95% CI: 1.018-1.261, P=0.022).

Awareness of diabetes knowledge and its influencing factors among health examination population / 中华健康管理学杂志

Objective:To investigate the awareness of diabetes knowledge among the health examination population and its influencing factors.Methods:A cross-sectional study. From september to november 2022, the subjects of six health examination centers located in six different cities (Beijing, Shanghai, Tianjin, Chongqing, Xiamen, Hangzhou) in China were investigated in the form of questionnaires to investigate the awareness of diabetes core information and the level of trust to different information sources of diabetes knowledge. According to the questionnaire results, the subjects were divided into a high awareness group of diabetes core information and a low awareness group. Logistic regression was used to analyze the influencing factors of diabetes core information awareness; the t-test was used to compare the trust degree of the two groups to different information sources. Results:A total of 9 315 people were included in the six centers, including 4 932 men (52.90%) with an average age of (39.36±12.64) years and 4 383 women (47.10%) with a mean age of (37.47±11.85) years. Only 36% of the people had high awareness of diabetes core information; variables such as gender, age, education level, physical examination frequency in the past three years, package price of this physical examination, self-evaluation of diabetes knowledge, diabetes status, and city of residence were variables that affect the level of awareness of core information related to diabetes (all P<0.05). Compared with the low awareness group of diabetes core information, the high awareness group trusted professional medical staff ( t=-9.597, P<0.05) and community health promotion more ( t=-5.014, P<0.05), but did not trust the emerging popular science propaganda means, such as WeChat official accounts/WeChat groups/QQ groups, Internet web page, Tiktok/Kwai and other short video APPs. Conclusion:The awareness rate of diabetes knowledge among the health examination population is low, and it is affected by many factors; Health education on diabetes knowledge should be carried out for people undergoing physical examination.
