Objectives: This study was aimed at establishing an ideal method for performing three-dimensional measurements of the fetus in order to improve the estimation of fetal weight.
Methods: The study consisted of two phases. Phase I was a prospective cross-sectional study performed between 28 and 40 weeks’ gestation. The study population (n=110) comprised low-risk singleton pregnancies who underwent a routine third-trimester sonographic estimation of fetal weight. The purpose of this phase was to establish normal values for the fetal abdominal and head volumes throughout the third trimester. Phase II was a prospective study that included patients admitted for an elective cesarean section or for induction of labor between 38 and 41 weeks’ gestation (n=91). This phase of the study compared the actual birth weight to two- (2D) and three-dimensional (3D) measurements of the fetus. Conventional 2D ultrasound fetal biometry was performed measuring the biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur diaphysis length (FL). Volume estimates were computed utilizing Virtual Organ Computer-aided AnaLysis (VOCAL), and the correlation between measured volumes and actual neonatal weight was calculated.
Results: Overall, this longitudinal study consisted of 110 patients between 28 and 41 weeks’ gestation. Normal values were computed for the fetal abdomen and head volume throughout the third trimester. Ultrasound examination was performed within three days prior to delivery on 91 patients. A good correlation was found between birth weight and abdominal volume (r=0.77) and between birth weight and head volume (r=0.5). Correlation between bidimensional measurements and actual fetal weights was found to be comparable with previously published correlations.
Conclusion: Volume measurements of the fetus may improve the accuracy of estimating fetal size. Additional studies using different volume measurement of the fetus are necessary.
Mueller is to be congratulated for a comprehensive and detailed exposition on medical professionalism. There is no question but that professionalism is important—however, Mueller is correct to point out the complexities of the subject and the fact that there is no single or simple way to teach or assess professionalism. ...
Whilst painting the vault of the Sistine Chapel, Michelangelo Buonarroti left an autographical sketch that revealed a prominence at the front of his hyper-extended neck. This image was recently diagnosed as goiter. The poet Michelangelo in a sonnet dated 1509 described himself as being afflicted by goiter similarly to the cats in the northern Italian Lombardy, a region with endemic goiter. Several narratives extended this sonnet into a pathological theory. The analyses of Michelangelo’s works, however, his portraits and self-portraits, of poems and major biographies, have not indicated the likelihood of goiter. This investigation makes an attempt to assess the diagnosis on clinical as well as iconographical grounds.
A great deal of biomedical research focuses on new biotechnologies such as gene editing, stem cell biology and reproductive medicine, which have created a scientific revolution. While the potential medical benefits of this research may be far-reaching, ethical issues related to non-medical applications of these technologies are demanding. We analyze, from a Jewish legal perspective, some of the ethical conundrums that society faces in pushing the outer limits in researching these new biotechnologies.
A 20-year-old female patient was admitted to hospital because of bilateral leg weakness. Laboratory investigation showed metabolic alkalosis and severe hypokalemia. Differential diagnosis included mineralocorticoid or apparent mineralocorticoid excess diseases, with a high aldosterone-to-renin ratio (ARR) after correcting hypokalemia. After confirmatory tests, imaging studies revealed a unilateral adrenocortical adenoma consistent with Conn’s disease. Surgery was curative.
I am pleased to announce that the winner of the 2018 Maimonides Best Published Original Research Prize is Dr. Louise Kezerle, the first author of the paper entitled, “A Population-based Study of Peripartum Cardiomyopathy in Southern Israel: Are Bedouin Women a New High-risk Group?” with co-authors Iftach M. Sagy, Leah Shalev, Offer Erez, and Leonid Barski.
Targeted therapies use an understanding of the pathophysiology of a disease in an individual patient. Although targeted therapy for systemic sclerosis (SSc, scleroderma) has not yet reached the level of patient-specific treatments, recent developments in the understanding of the global pathophysiology of the disease have led to new treatments based on the cells and pathways that have been shown to be involved in the disease pathogenesis. The presence of a B cell signature in skin biopsies has led to the trial of rituximab, an anti-CD20 antibody, in SSc. The well-known properties of transforming growth factor (TGF)-β in promoting collagen synthesis and secretion has led to a small trial of fresolimumab, a human IgG4 monoclonal antibody capable of neutralizing TGF-β. Evidence supporting important roles for interleukin-6 in the pathogenesis of SSc have led to a large trial of tocilizumab in SSc. Soluble guanylate cyclase (sGC) is an enzyme that catalyzes the production of cyclic guanosine monophosphate (cGMP) upon binding of nitric oxide (NO) to the sGC molecule. Processes such as cell growth and proliferation are regulated by cGMP. Evidence that sGC may play a role in SSc has led to a trial of riociguat, a molecule that sensitizes sGC to endogenous NO. Tyrosine kinases (TKs) are involved in a wide variety of physiologic and pathological processes including vascular remodeling and fibrogenesis such as occurs in SSc. This has led to a trial of nintedanib, a next-generation tyrosine-kinase (TK) inhibitor which targets multiple TKs, in SSc.
Current leading figures in medical science usually focus on very specific topics and use cutting-edge technologies to broaden our knowledge in the field. The working environment of the 19th century was much different. Medical giants of that time such as Rudolph Virchow and Thomas Hodgkin had a wide-ranging scope of research and humanitarian interests and made enormous contributions to a variety of core areas of medicine and the well-being of mankind. The year 2016 marked the 150th anniversary of the death of Dr. Thomas Hodgkin. Even a brief review of his life and work proves the current relevance of the outstanding deeds of this exceptional physician, medical educator, and defender of human rights for the poor and underprivileged; his vision was far ahead of his time.
The use of cocaine continues to grow worldwide. One of the possible side-effects of cocaine is vasculitis. Two distinct vasculitic syndromes have been described due to cocaine. One is cocaine-induced midline destruc¬tive lesion, secondary to a direct vasoconstrictor effect of cocaine, inducing ischemic necrosis of the septal cartilage and perforation of the nasal septum, mimicking findings of granulomatosis with polyangiitis in the upper airways. The other is ANCA-associated vasculitis, attributed to the levamisole component that contaminates about 70% of the cocaine. This type of vasculitis may be myeloperoxidase (MPO) and proteinase 3 (PR3) positive, and its main manifestations are typical cutaneous findings, arthralgia, oto¬laryngologic involvement, and agranulocytosis. A high degree of suspicion and awareness is needed in order properly to diagnose and treat these patients.
Born in Portugal and the son of Marranos (Christianized Jews from Spain), Eliahu de Luna Montalto lived during a particularly harsh period for the Jewish people. Throughout Europe, the situation for Jews was unfavorable; laws had been passed forbidding them to live in England for the past 300 years, and for the past 200 years in France. Additionally, in France, while Jews were permitted to study at some universities, the practice of medicine was forbidden to them. It is within this context that Eliahu de Luna Montalto, who had returned to his original faith (Judaism), was recruited to the French court. This paper pays tribute to Montalto’s life and medical practice—so exemplary that the Queen of France would ask Montalto to serve at the court and receive Papal permission for Montalto openly to observe his faith as a Jew, this despite the objections of the King of France.
