Objective: We hypothesized that ultrasound (US)-guided technique of the supra- and infraclavicular and axillary approaches of brachial plexus block (BPB) will produce a high quality of surgical anesthesia for operations below the shoulder independently of the approach and body mass index (BMI). Intercosto-brachial and medial brachial cutaneous nerves will be blocked separately because they are not a part of the brachial plexus.
Methods: This is a prospective randomized observer-blinded study. The three approaches of the US-guided BPB without neurostimulation were compared for quality, performance time, and correlation between performance time and BMI. Intercostobrachial and medial brachial cutaneous nerve blocks were used in all patients.
Results: A total of 101 patients were randomized into three groups: SCL (supraclavicular), ICL (infra-clavicular), and AX (axillary). Seven patients were excluded due to various factors. All three groups were similar in demographic data, M:F proportion, preoperative diagnosis and type of surgery, anesthesiologists who performed the block, and surgical staff that performed the surgical intervention. The time between the end of the block performance and the start of the operation was also similar. The quality of the surgical anesthesia and discomfort during the operation were identical following comparison between groups. No direct positive correlation was observed between BMI and the block performance time. The time for the axillary block was slightly longer than the time for the supra- and infraclavicular approaches, but it had no practical clinical significance. Transient Horner syndrome was observed in three patients in the SCL group. No other adverse effects or complications were observed.
Conclusions: All three approaches can be used for US-guided BPB with similar quality of surgical anesthesia for operations of below the shoulder. A block of the intercostobrachial and medial brachial cutaneous nerves is recommended. Obesity is not a significant factor in relation to the time of US-guided BPB performance, or the quality of surgical anesthesia. (ClinicalTrials.gov number, NCT01442558.)
Rabbi Moses Ben Maimon, known as Maimonides, or The “Rambam” (a Hebrew acronym for his name), was one of the greatest arbiters of all times on matters of Jewish law, one of the greatest philosophers of the Middle Ages, a scientist, and a researcher. In addition, he was a court physician to the Egyptian Sultan. In addition to his monumental work on Jewish law and ethics, his writings on medicine have been considered classics over the generations. The aim of this paper is to assess Maimonides’ health regimen and to compare his dietary recommendations with contemporary dietary regimens. To this end, Maimonides’ recommendations were compared to the modern guidelines of the United States, the Netherlands, and the World Health Organization (WHO), as well as to the Mediterranean diet, which is popular worldwide. Both marked similarities and contrasts were noted between Maimonides’ and modern recommendations. Most of Maimonides’ medical recommendations remain relevant more than 800 years later.
Determining appropriate care for patients who cannot speak for themselves is one of the most challenging issues in contemporary healthcare and medical decision-making. While there has been much discussion relating to patients who left some sort of instructions, such as an advance directive, or have someone to speak on their behalf, less has been written on caring for patients who have nobody at all available to speak for them. It is thus crucial to develop clear and rigorous guidelines to properly care for these patients. The Jewish tradition offers an important perspective on caring for unrepresented patients and determining approaches to guide care providers. This article develops an understanding of fundamental Jewish principles that can provide clear guidance in navigating this challenge. It applies those values to a specific set of suggested behaviors, one of which adds a novel ritualized component to what has been recommended by bioethicists in the past.
Background: Hyperinsulinemia and insulin resistance occurs in obese patients with primary hypertension independent of diabetes and obesity. This study was aimed at assessing serum fasting insulin levels, the homeostatic model assessment for insulin resistance (HOMA-IR), and serum lipid levels in non-obese patients with primary hypertension when compared to normotensive subjects.
Methods: This observational study comprised 100 patients over 18 years of age, divided into two groups. The hypertensive group comprised non-obese patients with primary hypertension (n=50); the normotensive group comprised normotensive age- and sex-matched individuals (n=50). Patients with diabetes, impaired fasting glucose, obesity, and other causative factors of insulin resistance were excluded from the study. Serum fasting insulin levels and fasting lipid profiles were measured, and insulin resistance was calculated using HOMA-IR. These data were compared between the two groups. Pearson’s correlation coefficient was used to assess the extent of a linear relationship between HOMA-IR and to evaluate the association between HOMA-IR and systolic and diastolic blood pressures.
Results: Mean serum fasting insulin levels (mIU/L), mean HOMA-IR values, and fasting triglyceride levels (mg/dL) were significantly higher in the hypertensive versus normotensive patients (10.32 versus 6.46, P<0.001; 1.35 versus 0.84, P<0.001; 113.70 versus 97.04, P=0.005, respectively). The HOMA-IR levels were associated with systolic blood pressure (r value 0.764, P=0.0005).
Conclusion: We observed significantly higher fasting insulin levels, serum triglyceride levels, and HOMA-IR reflecting hyperinsulinemia and possibly an insulin-resistant state among primary hypertension patients with no other causally linked factors for insulin resistance. We observed a significant correlation between systolic blood pressure and HOMA-IR.
There is universal agreement that the Nobel Prizes, given to individuals who have made an extraordinarily notable contribution to humankind in the fields of chemistry, physics, physiology or medicine, literature, and peace, are the most prestigious prizes offered for human achievement. This commentary gives an overview of the basis for Alfred Nobel writing his third will that established the five prizes and includes a discussion of why those five fields were chosen. The commentary includes factors that influenced his choices and contains examples of controversial selections or omissions, especially in the earlier years. A few were errors of omission (e.g. Tolstoy, Tesla, Edison, Best, Gandhi, Franklin), some errors of commission (e.g. Fibiger, Moniz); but, given the complexity of the task, the error rate is small. In some cases, the conclusion that an error had been made is debatable. Such decisions are difficult. Arne Tiselius, a Nobel laureate in chemistry and President of the Nobel Foundation said that one cannot in practice apply the principle that the Nobel Prize should be given to the person who is best; it is impossible to define who is best. Hence, there is only one alternative: to try to find a particularly worthy candidate. This paper includes a brief review of the integration of the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, established in 1968, and added to the original five Nobel Prizes; the prize was first awarded in 1969. A short discussion on the absence of a Nobel Prize in mathematics is provided. Adaptations to the development of “big” science, especially in physics, may require the Nobel Foundation to extend its limit of no more than three awardees for the prize in physics and, perhaps, other scientific disciplines.
Objective: To compare the results of treating patients with common bile duct (CBD) stones by endoscopic sphincterotomy (ES), surgical exploration, or a combination of ES and surgical CBD exploration (the rendezvous technique).
Methods: A narrative review of the literature.
Summary of Data: Before 1990, 17 cohort studies indicated that ES cleared CBD stones in 92.0% of patients, with a mortality rate of 1.5%. Surgery removed CBD stones in 90.2% of patients, with a 2.1% mortality rate. A single randomized controlled trial in 1987 showed that ES removed CBD stones in 91% of 55 patients, with a 3.6% mortality rate and a 27% complication rate, whereas surgical CBD exploration removed CBD stones in 92%, with a 1.8% mortality rate and a 22% complication rate. Since 1991, 26 randomized controlled trials have shown that laparoscopic–ES rendezvous is as effective as ES alone and laparoscopic surgery alone but is associated with fewer complications, a reduced need for additional procedures, and a shorter hospital stay.
Conclusions: A laparoscopic–ES rendezvous appears to be the optimal approach to the treatment of CBD stones in younger and fit patients. The choice between ES alone and laparoscopic–ES rendezvous in older or high-risk patients remains uncertain.
In December 2019, the first cases of a new contagious disease were diagnosed in the city of Wuhan, the capital of Hubei province in China. Within a short period of time the outbreak developed exponentially into a pandemic that infected millions of people, with a global death toll of more than 500,000 during its first 6 months. Eventually, the novel disease was named coronavirus disease 2019 (COVID-19), and the new virus was identified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Similar to all known pandemics throughout history, COVID-19 has been accompanied by a large degree of fear, anxiety, uncertainty, and economic disaster worldwide. Despite multiple publications and increasing knowledge regarding the biological secrets of SARS-CoV-2, as of the writing of this paper, there is neither an approved vaccine nor medication to prevent infection or cure for this highly infectious disease. Past pandemics were caused by a wide range of microbes, primarily viruses, but also bacteria. Characteristically, a significant proportion of them originated in different animal species (zoonoses). Since an understanding of the microbial cause of these diseases was unveiled relatively late in human history, past pandemics were often attributed to strange causes including punishment from God, demonic activity, or volatile unspecified substances. Although a high case fatality ratio was common to all pandemic diseases, some striking clinical character¬istics of each disease allowed contemporaneous people to clinically diagnose the infection despite null microbiological information. In comparison to past pandemics, SARS-CoV-2 has tricky and complex mech¬anisms that have facilitated its rapid and catastrophic spread worldwide.
Objectives: This document provides an English translation of the Israeli Joint Commission’s national guidelines for triaging severely ill patients during the coronavirus disease 2019 (COVID-19) pandemic.
Methods: Four subcommittees of medical, legal, ethical-social, and religious experts developed the general principles and practical medical criteria for triaging scarce life-saving resources.
Results: The guidelines provide an overview of general principles as well as pragmatic medical criteria and a practical triage protocol to be followed should the healthcare system be overwhelmed due to COVID-19. Issues covered include triggers for activating the guidelines, guiding ethical, legal, and religious principles, equity in access, fair distribution, transparency, consistency, palliation, medical policy prioritization, problem-solving mechanisms, and public trust.
Conclusions: The Israeli consensus document and pragmatic medical triage protocol offer a societal and medical roadmap for allocating scarce resources during the COVID-19 pandemic or other disasters.
During the coronavirus disease 2019 (COVID-19) pandemic, the increasing fear of leaving home and entering hospitals, together with guidelines to the public from Israel’s Ministry of Health recommending the use of telemedicine rather than physical visits to the doctor, led to delayed diagnoses of non-COVID-19-related medical conditions. This research letter presents a cluster of severe medical conditions that were delayed in diagnosis due to postponed presentation to healthcare facilities during the COVID-19 pandemic. Ewing sarcoma, severe hemolytic anemia, endocarditis requiring surgery, and septic hip requiring surgery are some examples of cases we encountered with delayed diagnoses. This led to the appearance of a rather low burden of disease in the pediatric population during the pandemic, and pediatric hospitals and clinics experienced a very low volume of activity. Given the low burden of COVID-19 in children, and the well-defined separation between infected and non-infected areas within the hospitals, we should consider improving the guidelines and messages conveyed to the public regarding the importance of prompt medical assessment for other medical conditions, even during a pandemic, along with reassurance of the safety of entering medical facilities given the strict isolation procedures being observed. Conclusion: Medical associations should reconsider the messages being sent to the public during future outbreaks, and encourage medical assessment.
Quantification of the T cell receptor excision circles (TRECs) has recently emerged as a useful non-invasive clinical and research tool to investigate thymic activity. It allows the identification of T cell production by the thymus. Quantification of TREC copies has recently been implemented as the preferred test to screen neonates with severe combined immunodeficiency (SCID) or significant lymphopenia. Neonatal genetic screening for SCID is highly important in countries with high rates of consanguinous marriages, such as Israel, and can be used for early diagnosis, enabling prompt therapeutic intervention that will save lives and improve the outcome of these patients. TREC measurement is also applicable in clinical settings where T cell immunity is involved, including any T cell immunodeficiencies, HIV infection, the aging process, autoimmune diseases, and immune reconstitution after bone marrow transplantation.
TAKE-HOME MESSAGES
• Severe combined immunodeficiency, a life-threatening condition, can be detected by neonatal screening.
• The earlier the detection and the quicker the implementation of appropriate treatment, the greater the likelihood for improved outcome, even cure, for the affected children.
• TRECs and KRECs quantification are useful screening tests for severe T and B cell immunodeficiency and can be used also to evaluate every medical condition involving T and B cell immunity.
