Fat-soluble vitamins, including vitamins A, D, E and K, are molecules with no energy value that are essential for the body to function and for life. Their intake is almost exclusively exogenous, i.e. dietary. The ubiquitous and vital nature of the functions performed by these vitamins explains the wide variety of clinical manifestations and their potential seriousness, particularly in cases of deficiency, but also in cases of excess or hypervitaminosis. We present here the main symptoms of hypervitaminosis. [ABSTRACT FROM AUTHOR]

Fat-soluble vitamins, including vitamins A, D, E and K, are molecules with no energy value that are essential to the body's functioning and to life. Their intake is almost exclusively exogenous, i.e. dietary. Deficiency or excess of fat-soluble vitamins is responsible for a variety of more or less specific clinical symptoms. The fact that the functions performed by these vitamins are both ubiquitous and vital explains the wide variety of clinical manifestations and their potential seriousness. Some syndromes are typical of a deficiency in fat-soluble vitamins, such as: the combination of ophthalmological and immunity impairment in the case of vitamin A; a haemorrhagic syndrome and osteopenia in the case of vitamin E; and osteomalacia, muscular weakness, even falls, and rickets in the case of vitamin D. Diagnosis of a deficiency in one of the fat-soluble vitamins is based on blood tests, which are not always essential for routine use. In this case, a therapeutic test may be suggested.

Background/Objectives: Vitamin B12 deficiency can cause variable symptoms, which may be irreversible if not diagnosed and treated in a timely manner. We aimed to develop a widely accepted expert consensus to guide the practice of diagnosing and treating B12 deficiency. Methods: We conducted a scoping review of the literature published in PubMed since January 2003. Data were used to design a two-round Delphi survey to study the level of consensus among 42 experts. Results: The panelists agreed on the need for educational and organizational changes in the current medical practices for diagnosing and treating B12 deficiency. Recognition of clinical symptoms should receive the highest priority in establishing the diagnosis. There is agreement that the serum B12 concentration is useful as a screening marker and methylmalonic acid or homocysteine can support the diagnosis. Patient lifestyle, disease history, and medications can provide clues to the cause of B12 deficiency. Regardless of the cause of the deficiency, initial treatment with parenteral B12 was regarded as the first choice for patients with acute and severe manifestations of B12 deficiency. The use of high-dose oral B12 at different frequencies may be considered for long-term treatment. Prophylactic B12 supplementation should be considered for specific high-risk groups. Conclusions: There is a consensus that clinical symptoms need to receive more attention in establishing the diagnosis of B12 deficiency. B12 laboratory markers can support the diagnosis. The severity of clinical symptoms, the causes of B12 deficiency, and the treatment goals govern decisions regarding the route and dose of B12 therapy. [ABSTRACT FROM AUTHOR]

Résumé: Introduction: L'artérite à cellules géantes (ACG) ou maladie de Horton est une artérite inflammatoire segmentaire et focale des artères de gros et moyen calibre du sujet de plus de 50 ans, avec un pic de fréquence chez le sujet très âgé entre 70 et 80 ans. Dans cette classe d'âge et au-delà de 80 ans, les données cliniques concernant l'AGC sont peu nombreuses. Notre objectif est de documenter ces dernières à travers une étude monocentrique menée sur une population avec une AGC avérée. Patients et méthode: Nous avons mené une étude rétrospective, monocentrique sur les dossiers médicaux de patients diagnostiqués artérite de Horton selon les critères de l'ASR entre 2012 et 2017 au CHU de Reims. Pour évaluer l'influence de l'âge sur le plan diagnostic, thérapeutique, du suivi et du pronostic, nous avons comparé des patients de 75 ans et moins (≤ 75 ans) à ceux de plus de 75 ans (> 75 ans) sur ces différents points. Résultats: Soixante-sept patients ont été inclus. L'âge moyen au diagnostic de ces patients était de 75,85 ± 8,5 ans ; 36 patients (53,7 %) étaient âgés de 75 ans ou moins (dont 22 femmes) et 31 patients (46,3 %) étaient âgés de plus de 75 ans (dont 21 femmes). La médiane de suivi était de 43,02 mois chez les patients ≤ 75 ans et de 30,99 mois chez les > 75 ans, soit près d'un an de différence, mais non significative (p = 0,620). Onze patients (16,4 %) étaient décédés au cours du suivi, 5 (13,9 %) chez les patients ≤ 75 ans et 6 (19,4 %) chez les patients de > 75 ans (p = 0,547). Les patients > 75 ans avaient significativement moins d'aortite (p = 0,0410). Il y avait une tendance à moins de rechute chez les patients de > 75 ans (p = 0,067). Pour les autres symptômes ou anomalies biologiques, les résultats de la biopsie d'artère temporale, la prise en charge thérapeutique, les complications iatrogènes et les décès, aucune différence significative n'était mise en évidence entre les deux groupes (p = ns). Conclusion: Notre étude montre peu de différence en ce qui concerne l'AGC entre les patients > 75 ans et ceux ≤ 75 ans. Toutefois, les patients > 75 ans ont moins d'aortite que les sujets plus jeunes. Il semble également y avoir une tendance à davantage de rechute chez les sujets les plus jeunes, sous réserve d'une durée de suivi plus courte d'un an, cliniquement pertinente, chez les sujets les plus âgés. Introduction: Giant cell arteritis (GCA) or Horton's disease is a segmental and focal inflammation of large and medium-sized arteries mostly seen in patients of 50 years and older. There is also a peak frequency in individuals between the ages of 70 and 80. However, clinical data is scarce in this age group and especially in patients over 80. Methods: A retrospective study comprised of patients diagnosed with Horton's arteritis between 2012 and 2017, according to the American Society of Rheumatology, was conducted at Reims University Hospital. Patients were assigned to two groups according to age (≤ 75 and < 75) in order to evaluate and compare the impact of age on diagnosis, treatment and prognosis. Results: A total of 67 patients were studied. The mean age upon diagnosis was 75,85 ±8.5 years; 36 patients (53.7%) 75 years or younger and 31 patients older than 75. There was a female predominance (43 patients), 22 patients aged 75 years or younger and 21 older than 75. The mean follow up duration was 43.02 months in patients aged 75 years or younger and 30.99 in patients older than 75. This represents a difference of more than one year in terms of follow up, but is not statistically significant (p = 0.620). Eleven patients (16.4%) died during follow up: 5 patients (13.9%) aged 75 years or younger and 6 patients (19.4%) older than 75 (p = 0.547). Aortitis was significantly less seen in patients older than 75 (p = 0.0410). Conclusion: Our study showed no significant difference in either age group. However, aortitis was less seen in patients older than 75 years. Patients aged 75 or younger seemed more prone to relapses, but their follow up periods were shorter. [ABSTRACT FROM AUTHOR]

Background: Today learning ausculation is still based on empirical tutoring. Objective: The aim of this study is to analyze the contribution of a structured teaching method combined with new phono- and spectrogram signal-visualization tools for medical students. Methods: The study included 30 graduate medical students who analyzed 10 respiratory- and cardiac-disease sounds (ASAP (Analyse des Sons Auscultatoires et Pathologiques) data (ANR Technology 2006)), with and without the contribution of phono- and spectrograms. To evaluate the accuracy of student diagnoses, a questionnaire was handed out at D0 (acoustic data) and D28 (acoustic and visual data) after which results were compared. Results: At D0, 45% of student diagnoses were accurate, including 40% for the DCEM2 (graduate medical studies), and respectively 43% and 60% for the DCEM3 (graduate medical studies) and DCEM4 (graduate medical studies). With respect to respiratory and cardiac sounds, the diagnostic accuracy was respectively 51% and 40%. At D28, 80% of students reported correct diagnoses (p < 0.01 compared to D0), with 70% diagnostic accuracy for respiratory sounds (p = 0.058) and 89% for heart sounds (p < 0.009). Conclusion: The study conducted with graduate medical students objectifies improved diagnosis accuracy using diagnostic tools such as phono- and spectrograms and a structured teaching method.

Abstract: Auscultation of pulmonary sounds provides valuable clinical information but has been regarded as a tool of low diagnostic value due to the inherent subjectivity in the evaluation of these sounds. This paper describes an ambitious study of in the so-called ASAP project or “Analyse de Sons Auscultatoires et Pathologiques”. ASAP is a 3-year-long French collaborative project developed in the context of the News Technologies of Information and Communication. ASAP aims at making evolve the auscultation technics: by 1) the development objective tools for the analyse of auscultation sounds: electronic stethoscopes paired with computing device; 2) the creation of an auscultation sounds'' database in order to compare and identify the acoustical and visual signatures of the pathologies; and 3) the capitalisation of these new auscultation techniques around the creation of a teaching unit: “Ecole de l''Auscultation”. This auscultation''s school will be destined to the initial and continuous formation of the medical attendants. [Copyright &y& Elsevier]

Background: The aim of our study was to compare the value of the Von Reyn and the Duke diagnostic criteria for infective endocarditis (IE) in internal medicine practice. Methods: We determined the sensitivity and negative predictive value of these two sets of diagnostic criteria in 38 patients with established infective endocarditis who were followed in two departments of general internal medicine. The patients essentially had subacute endocarditis of the aortic valve (79%) with several systemic manifestations (100%). Microbial documentation included mainly gram-positive cocci (60%). Results: With transthoracic echocardiography (TTE), the sensitivities of the Duke and the Von Reyn criteria were 65% and 35%, respectively, while with transesophageal echocardiography (TEE), these sensitivities were 75% and 35%, respectively. With TTE and TEE, the negative predictive values were 100% for the Duke diagnostic criteria versus only 71% for the Von Reyn criteria. Conclusions: This study confirms that the Duke diagnostic criteria are useful in practice for the management of patients with infective endocarditis followed in internal medicine.

Recently, concerns have been raised about an increased risk of cardiac sarcoidosis in patients with sarcoid uveitis. While cardiac sarcoidosis has a high mortality burden, there is still a lack of precise data on this association. The objective of this study is to describe the frequency and type of cardiac complications associated with sarcoidosis of a large cohort of patients with sarcoid uveitis. We analyzed the cardiac outcomes of a monocentric retrospective cohort of consecutive adults with a diagnosis of sarcoid uveitis between January 2004 and March 2020 in a tertiary French university hospital. A total of 294 patients with a final diagnosis of sarcoid uveitis were included. At final follow-up, seven (2.4%) patients of the cohort had cardiac sarcoidosis. Cardiac sarcoidosis was more frequent among patients with previously reported systemic sarcoidosis (p = 0.008). The prevalence of cardiac sarcoidosis among patients with sarcoid uveitis is low, but patients with previously diagnosed sarcoidosis or those who develop systemic sarcoidosis during follow-up appear to be at increased risk.
