BACKGROUND: The energy crisis hypothesis, which is a widely accepted model for the pathogenesis of myofascial pain, has been corroborated by experimental observations. However, the nature of the insult leading to the energy crisis remains elusive. A commonly cited model for this insult is the Cinderella hypothesis, suggesting that hierarchical recruitment of motor units leads to a disproportional load on small units, thus driving them towards an energy crisis. New findings cast doubt on this model, showing that in postural muscles motor units are recruited in rotation, rather than in a hierarchical order, precluding the formation of the so-called Cinderella units.
OBJECTIVE: To explore the influence of common myofascial predisposing factors such as muscle load and muscle strength on the relaxation time of postural muscle motor units, assuming they are recruited in rotation.
METHODS: A stochastic model of a postural skeletal muscle was developed which integrates the energy crisis model and motor unit rotation patterns observed in postural muscles. Postulating that adequate relaxation time is essential for the energetic replenishment of motor units, we explored the influence of different parameters on the relaxation time of individual motor units under varying conditions of muscle loads and muscle strengths.
RESULTS: The motor unit relaxation/contraction time ratio decreases with elevated muscle loads and with decreased total muscle strength.
Conclusions: In a model of a postural muscle, in which motor units are recruited in rotation, common predisposing factors of myofascial pain, such as increased muscle load and decreased muscle force, lead to shortened motor unit relaxation periods.
Background: The importance of emotional intelligence (EI) to the success of health professionals has been increasingly acknowledged. Concurrently, medical schools have begun integrating non-cognitive measures in candidate selection processes. The question remains whether these newly added processes correctly assess EI skills.
Objectives: Measuring EI levels among medical students; examining the correlations between participants’ EI levels and their scores on the non-cognitive MOR test; and exploring students’ attitudes regarding the importance of EI in medical practice.
Methods: The study included 111 first-year and sixth-year students at the Faculty of Medicine at the Technion, Haifa, Israel. Emotional intelligence was assessed by the Bar-On EQ-i 2.0, and MOR evaluation scores were provided by the faculty. An additional questionnaire was designed to rate students’ attitudes toward the importance of EI to the success of medical doctors (MDs).
Results: No significant correlations were found between MOR test scores and EI evaluation scores. Of the 15 EI competencies evaluated, mean scores for flexibility, problem-solving, and independence were lowest for both the first-year and the sixth-year study groups. No differences in EI levels between first-year and sixth-year students were found. Both groups of students considered EI to be highly important to their success as MDs.
Conclusions: While further studies of the links between MOR tests and EI are required, the current findings indicate that MOR test scores may not be predictive of medical students’ EI levels and vice versa. As previous evidence suggests that EI contributes to professional success and to better outcomes in the field of medicine, integrating it into selection processes for medical students and into the curricula in medical schools is recommended.

Background: United States (US) and European Union (EU) legislation attempts to counterbalance the presumed discrimination in pediatric drug treatment and development.
Methods: We analyzed the history of drug development, US/EU pediatric laws, and pediatric studies required by US/EU regulatory authorities and reviewed relevant literature.
Results: The US and EU definitions of a child are defined administratively (rather than physiologically) as being aged <17 years and <18 years, respectively. However, children mature physiologically well before their seventeenth or eighteenth birthdays. The semantic blur for these differing definitions may indicate certain conflicts of interest.
Conclusions: Pediatric healthcare today is better than ever. Regulatory-related requirements for “pediatric” studies focus on labeling. Most of these studies lack medical usefulness and may even harm pediatric patients through administration of placebo and/or substandard treatment, despite the resultant publications, networking, patent extensions, and strengthened regulatory standing. Clinicians, parents, and ethics committees should be aware of these issues. New rules are needed to determine new pharmaceutical dose estimates in prepubescent patients, and when/how to clinically confirm them. Internet-based structures to divulge this information should be established between drug developers, clinicians, and regulatory authorities. A prerequisite for the rational use of pharmaceuticals in children would be to correct the flawed concept that children are discriminated against in drug treatment and development, and to abandon separate pediatric drug approval processes.
Objective: To review current medical literature on the risks and potential benefits of e-cigarette use and its permissibility under Jewish law.
Methods: A survey of current medical literature about the risks and potential benefits of e-cigarette use, and a review of existing rabbinic literature regarding both combustible and e-cigarette products.
Results: E-cigarettes contain fewer harmful materials than do combustible cigarettes. However, they are not risk-free. Their skyrocketing use among youth is of concern, as e-cigarettes lead to nicotine addiction and are a gateway to combustible cigarettes. Preliminary data indicate that e-cigarettes increase the risk of myocardial infarction, chronic obstructive pulmonary disease (COPD), and emphysema and are no more effective as aids to smoking cessation than US Food and Drug Administration (FDA)-approved interventions with acceptable safety profiles. Few halakhic decisors have opined on the permissibility of e-cigarettes, but extrapolating from halakhic discussions regarding combustible cigarettes strongly suggests that they would prohibit e-cigarettes based on government warnings and preliminary data demonstrating increased risk of cardiovascular and respiratory diseases, at the least because of possible danger (safek sakana). Among youth and pregnant women, for whom e-cigarettes are particularly dangerous and for whom the government has administered explicit warnings, a Jewish legal prohibition should be absolute. There is a unique obligation to prevent youth from obtaining these products. Jewish law might also prohibit deriving benefit from the sale or advertisement of these products.
Conclusions: Extrapolating from rabbinic literature regarding combustible cigarettes, the preliminary data establishing the dangers of e-cigarettes and the government warnings against usage would render these products prohibited under Jewish law, especially for youth and pregnant women.
Objective: The World Health Organization’s (WHO) guidelines for cancer pain management were intentionally made simple in order to be widely implemented by all physicians treating cancer patients. Referrals to pain specialists are advised if pain does not improve within a short time. The present study examined whether or not a reasonable use of the WHO guideline was made by non-pain specialists prior to referral of patients with cancer-related pain to a pain clinic.
Methods: Cancer patients referred to a pain specialist completed several questionnaires including demographics, medical history, and cancer-related pain; the short-form McGill Pain Questionnaire (SF-MPQ); and the Short Form Health Survey SF-12. Data from referral letters and medical records were obtained. Treatments recommended by pain specialists were recorded and categorized as “unjustified” if they were within the WHO ladder framework, or “justified” if they included additional treatments.
Results: Seventy-three patients (44 women, 29 men) aged 55 years (range, 25–85) participated in the study. Their pain lasted for a mean of 6 (1–192) months. Mean pain intensity scores on a 0–10 numerical rating scale were 7 (2–10) at rest and 8 (3–10) upon movement. Most patients complied with their referring physician’s recommendations and consumed opioids. Adverse events were frequent. No significant correlation was found between the WHO analgesic medication step used and mean pain levels reported. There were 63 patient referrals (85%) categorized as “unjustified,” whereas only 11 patients (15%) required “justified” interventions.
Conclusions: These findings imply that analgesic treatment within the WHO framework was not reasonably utilized by non-pain specialists before referring patients to pain clinics.
To the Editor,
I am writing in response to Dr Sharon Galper Grossman’s recent fascinating article, “Vape Gods and Judaism—E-cigarettes and Jewish Law.”1 The author extrapolates from rabbinic literature regard-ing combustible cigarettes and suggests that the preliminary data establishing the dangers of e-cigarettes, and the government warnings against usage, would render these products prohibited under Jewish law, especially for youth and pregnant women.
United States (US) and European Union (EU) laws attempt to counterbalance the presumed discrimination of children in drug treatment and drug development. The US Food and Drug Administration (FDA)-rewarded pediatric studies with antidepressants triggered in 2004 an FDA black-box warning of suicidality in young patients. Fewer antidepressants were prescribed, and the number of completed suicides of young persons increased. The dilemma between this warning and the need to adequately treat young depressed patients remains unsolved. We analyzed the history of drug development, the evolving view of diseases in young patients, US/EU pediatric laws, and pediatric studies triggered by FDA/European Medicines Agency (EMA) in depression and other diseases on the background of developmental pharmacology; financial, institutional, and other interests; and the literature. The FDA/EMA define children administratively, not physio¬logically, as <17 (FDA)/<18 years old (EMA). But young persons mature physiologically well before their 17th/18th birthday. Depression occurs in young persons, has special characteristics, but is not fundamentally different from adult depression. Young persons are not another species. Regulatory requirements for “pediatric” studies focus on “pediatric” labels. Many “pediatric” studies, including those in depression, lacked and lack medical sense and harm patients by placebo treatment although effective drugs exist. The FDA has partially abandoned separate “pediatric” efficacy studies, but not in psychiatry. Clinicians, parents, institutional review boards, and ethics committees should become aware of questionable “pediatric” studies, should re-evaluate ongoing ones, consider to suspend them, and to reject new ones. The concept of separate “pediatric” drug approval needs to be abandoned.
Objectives: To analyze, perioperatively and in follow-up, transilluminated powered phlebectomy (TIPP), a surgical technique for the treatment of varicose veins.
Method: Retrospective study in one medical institution of patients undergoing TIPP between July 2015 and December 2017. Data analyzed included demographic data, surgery, and results. Postoperatively, pain was evaluated by a 10-point visual analogue scale. The Venous Clinical Severity Score (VCSS) was assessed 5–8 weeks following surgery.
Results: Sixty-six patients with extensive varicosities who underwent TIPP were included. Postoperative pain scores were higher in patients undergoing bilateral compared to unilateral TIPP (visual analogue score 7 versus 5; P=0.031). Following surgery, the VCSS improved in 81.8% (54/66) of the patients. However, 39.7% (25/63; data missing in 3 patients) reported that they would not be willing to undergo a similar procedure in the future. Pain was the most common reason for dissatisfaction.
Conclusions: Transilluminated powered phlebectomy was associated with considerable pain and discom¬fort in many patients included in this study. For this reason, it should be reserved for a select group of patients in whom other treatment options are limited; TIPP could be considered in the following cases: patients with a large number of varicosities, reoperations, after extensive thrombophlebitis, obesity, or following bariatric surgery.
The development of the modern hospital is usually dated to the nineteenth century. During this time, many municipal and sectarian hospitals were established and developed, and Jewish hospitals were no exception. Such developments also occurred in the Netherlands. This essay describes the different histories of the Jewish hospitals in Rotterdam and The Hague during the nineteenth century. The Rotterdam institution lasted for more than 130 years (until it was closed by the Nazis during the Second World War), whereas the one in The Hague existed for only 31 years. This study will suggest a number of possible explanations for the relatively long and successful history of the Jewish hospital in Rotterdam and the contrastingly brief duration of the Jewish hospital in The Hague.
