Background: Travelers' diarrhea (TD) is frequently encountered in people traveling from high-income to low-income countries; however, its epidemiology in those traveling between high-income countries is not known.

Objectives: To evaluate the incidence of diarrhea in North American students relocating to Israel.

Methods: A retrospective cohort study involving medical students from the United States and Canada relocating to Israel was conducted. Students who relocated to Israel during 2010–2016 were contacted by email to participate in an anonymous survey. Data included demographic information as well as occurrence, timing, duration, and outcome of diarrhea after relocation.

Results: Ninety-seven students participated in the survey. Most (93.7%) students relocated from the United States or Canada. The period-prevalence of diarrhea was 69.1%. The incidence of diarrhea declined from 34.8 cases per 100 student-months during the first month after relocation to 1.3 cases per 100 student-months after 1 year. The duration of diarrhea was up to 1 week in 72.7%. Students who reported diarrhea were younger than students who did not (mean age 24.0 ± 2.2 and 28.4 ± 1.8 years, respectively, P < 0.001). No other demographic parameter was significantly associated with a higher likelihood of diarrhea.

Conclusions: A high proportion of North American medical students relocating to Israel reported diarrhea with clinical and epidemiological features similar to classic TD. Further studies are needed to elucidate the causative agents of TD in Israel.

Spinal manipulation therapy (SMT) is commonly used as an effective therapeutic modality for a range of cervical symptoms. However, in rare cases, cervical manipulation may be associated with complications. In this review we present a series of cases with cervical spine injury and myelopathy following therapeutic manipulation of the neck, and examine their clinical course and neurological outcome. We conducted a search for patients who developed neurological symptoms due to cervical spinal cord injury following neck SMT in the database of a spinal unit in a tertiary hospital between the years 2008 and 2018. Patients were assessed for the clinical course and deterioration, type of manipulation used and subsequent management. A total of four patients were identified, two men and two women, aged 32–66 years. In three patients neurological deterioration appeared after chiropractic adjustment and in one patient after tuina therapy. Three patients were managed with anterior cervical discectomy and fusion while one patient declined surgical treatment. Assessment for subjective and objective evidence of cervical myelopathy should be performed prior to cervical manipulation, and suspected myelopathic patients should be sent for further workup by a specialist familiar with cervical myelopathy (such as a neurologist, a neurosurgeon or orthopedic surgeon who specializes in spinal surgery). Nevertheless, manipulation therapy remains an important and generally safe treatment modality for a variety of cervical complaints. This review does not intend to discard the role of SMT as a significant part in the management of patients with neck related symptoms, rather it is meant to draw attention to the need for careful clinical and imaging investigation before treatment.

The Bedouins living in southern Israel are a Muslim-Arab population that is transitioning from a nomadic lifestyle to life in permanent settlements. The population has unique characteristics that could affect hemoglobin A1c (HbA1c) measurements. The objective of this study was to describe the socio-demographic and unique morbidity characteristics of this community and their effect on HbA1c measurements. Consanguinity, especially among cousins in the Bedouin population, results in a high prevalence of autosomal recessive genetic diseases such as thalassemia (underestimate of HbA1c), hemoglobinopathies (underestimate and overestimate), Gilbert’s disease, and glucose-6-phosphate dehydrogenase deficiency, an X-linked disorder, which can cause hyperbilirubinemia with an overestimate of HbA1c. Furthermore, nutritional deficiencies, autosomal recessive diseases, high birth rates, parasitic infections, and poverty can all cause high rates of anemia (iron and vitamin B12 deficiencies) that can raise HbA1c levels. Congenital dyserythropoietic anemia is found among Bedouin tribes in the Negev region and can lead to an underestimation of HbA1c levels. Pregnancy can also affect HbA1c levels. Medical teams working in the Bedouin community and in other Muslim populations with similar morbidity characteristics throughout the world should identify patients with medical conditions that can affect HbA1c measurements and be aware of possible measurement alternatives such as fructosamine and glycated albumin.

Global trends, such as the population aging, the increase of chronic morbidity, soaring costs of healthcare services, and work overload in hospitals raise the need to find innovative solutions for providing quality medical services. One solution adopted by healthcare systems around the world is "home hospitalization," that is, providing an array of necessary health services in the patient's home, instead of in the hospital department. The aim of this focus article is to explore the spread of home hospitalization worldwide and examine the challenges and pathways for its adoption and implementation. Many countries, including the United States, Canada, the United Kingdom, and Australia, operate home-based hospitalization programs. In Israel, the service is in its infancy, but in view of the extreme workload and the high mortality rate from infections in acute care hospitals, home hospitalization has recently gained public interest and political support, which may encourage its further development.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by the progressive death of motor neurons leading to fatal paralysis. The causes of ALS remain unknown; however, evidence supports the presence of autoimmune mechanisms contributing to pathogenesis. Although several environmental factors have been proposed, the only established risk factors are older age, male gender, and a family history of ALS. To date, there are no diagnostic test for ALS, and clinicians rely on the combination of upper motor neuron and lower motor neuron signs in the same body region. The aim of this paper was to provide a comprehensive review of current clinical literature with special focus on the role of autoimmunity in ALS, differential diagnosis, and available therapeutic approaches. Current evidence suggests a contribution of the innate immune system in ALS, with a role of microglial cell activation at the sites of neurodegeneration. The median time from symptom onset to diagnosis of ALS is 14 months, and this time estimate is mainly based on specific clinical signs and exclusion of ALS-like conditions. Several therapeutic approaches have been proposed, including immunosuppressive drugs, to reduce disease progression. Riluzole has been established as the only, although modestly effective, disease modifying therapy, extending mean patient survival by 3to 6 months. Recent advances in understanding the pathophysiology mechanisms of ALS encourage realistic hope for new treatment approaches. To date, the cornerstones of the management of patients with ALS are focused on symptom control, maintaining quality of life and improving survival.

Background: Fibromyalgia is a syndrome of unknown etiology that is characterized by widespread pain, which severely impairs quality of life. Several forms of occupational and alternative therapy have demonstrated beneficial effects in fibromyalgia patients.

Objective: To assess the effects of participation in a floral design course on physical and psychiatric symptoms in a cohort of fibromyalgia patients.

Methods: This study was conducted as an observational study. Women diagnosed with fibromyalgia over the age of 18 were recruited to participate in one of two 12-week flower design (floristry) courses. Demographic details, disease activity indices, and anxiety and depression scores were calculated for all participants at baseline, week 12, and study completion. Physical and mental health of the two groups were compared throughout the study time-points.

Results: The study was completed by 61 female fibromyalgia patients who were included in the final analyses; 31 patients participated in the first floristry course and 30 in the second. Significant improvements in the 36-Item Short Form Survey physical and mental health components, visual analog scale, Fibromyalgia Impact Questionnaire, Hamilton Anxiety Rating Scale, and Hamilton Depression Rating Scale scores for the entire study population and for each group separately could be seen following participation in each floristry course.

Conclusions: Participation in a floristry course may lead to a significant improvement in pain and psychiatric symptoms in fibromyalgia patients. These findings highlight the potential benefit of utilizing occupational therapy programs, such as a floristry course, for improving quality of life in fibromyalgia.
