The 'creatures' of the human cortical somatosensory system.

Penfield's description of the 'homunculus', a 'grotesque creature' with large lips and hands and small trunk and legs depicting the representation of body-parts within the primary somatosensory cortex (S1), is one of the most prominent contributions to the neurosciences. Since then, numerous studies have identified additional body-parts representations outside of S1. Nevertheless, it has been implicitly assumed that S1's homunculus is representative of the entire somatosensory cortex.

The Association Between PHQ-9 and Fitness for Work Among Depressive Patients.

Objective: One of the tools to assess depression severity is the Patient Health Questionnaire (PHQ-9). Our aim was to investigate the correlation between PHQ-9 scores and fitness for work (FFW) in major depressive disorder (MDD).

Methods: A cross-sectional study in patients who were evaluated for their FFW and later compared with PHQ-9.

Hierarchical cortical gradients in somatosensory processing.

Sensory information is processed in the visual cortex in distinct streams of different anatomical and functional properties. A comparable organizational principle has also been proposed to underlie auditory processing. This raises the question of whether a similar principle characterize the somatosensory domain.

The effect of multidrug exposure on neurological manifestations in carbamazepine intoxication: a nested case-control study.

Background: In acute intoxication, carbamazepine concentration above 40 mcg/ml is associated with a risk of severe neurological consequences, including depressed consciousness, respiratory depression, cardiac conduction disorders, seizures, and death. Carbamazepine intoxication is often associated with the use of concomitant medications. However, the effect of exposure to other central-nervous-system (CNS) acting medications on the neurological manifestations of carbamazepine toxicity has not been evaluated.

Nasopharyngeal carcinoma in children and young adults-Beyond 5-year survival.

Nasopharyngeal carcinoma (NPC) is a rare and locally aggressive form of childhood cancer. Treatment of NPC includes chemotherapy and radiotherapy. With current treatment protocols, survival rates for patients with nonmetastatic disease is over 80%.

The radiation of autonoetic consciousness in cognitive neuroscience: A functional neuroanatomy perspective.

One of Endel Tulving's most important contributions to memory research is the coupling of self-knowing consciousness (or "autonoesis") with episodic memory. According to Tulving, autonoetic episodic memory enables the uniquely human neurocognitive operation of "mental time travel", which is the ability to deliberately "project" oneself to a specific time and place to remember personally experienced events that occurred in the past and simulate personal happenings that may occur in the future. These ideas ignited an explosion of research in the years to follow, leading to the development of several related concepts and theories regarding the role of the human self in memory and prospection.

Ultrasound guided tattooing of axillary lymph nodes in breast cancer patients prior to neoadjuvant therapy, and identification of tattooed nodes at the time of surgery.

Background: Breast cancer patients with lymph node (LN) metastases at diagnosis often undergo neoadjuvant therapy (NAT). Identification of a LN which regressed after NAT remains a challenge.

Objective: To evaluate marking of involved nodes by tattooing with carbon suspension, and identifying these nodes during surgery.

International perspectives on the implementation of reproductive carrier screening.

Reproductive carrier screening started in some countries in the 1970s for hemoglobinopathies and Tay-Sachs disease. Cystic fibrosis carrier screening became possible in the late 1980s and with technical advances, screening of an ever increasing number of genes has become possible. The goal of carrier screening is to inform people about their risk of having children with autosomal recessive and X-linked recessive disorders, to allow for informed decision making about reproductive options.

Characterization and genotype-phenotype correlation of patients with Fanconi anemia in a multi-ethnic population.

Fanconi anemia (FA), an inherited bone marrow failure (BMF) syndrome, caused by mutations in DNA repair genes, is characterized by congenital anomalies, aplastic anemia, high risk of malignancies and extreme sensitivity to alkylating agents. We aimed to study the clinical presentation, molecular diagnosis and genotype-phenotype correlation among patients with FA from the Israeli inherited BMF registry. Overall, 111 patients of Arab (57%) and Jewish (43%) descent were followed for a median of 15 years (range: 0.

Traumatic Cataracts in Children, Long-Term Follow-up in an Israeli Population: A Retrospective Study.

Background: Ocular trauma in the pediatric population may lead to cataract formation. Managing traumatic cataracts in a visually immature child is a major challenge and can result in poor visual outcome.

Objectives: To review our long-term surgical experience with childhood unilateral traumatic cataracts.

Processing of different spatial scales in the human brain.

Humans navigate across a range of spatial scales, from rooms to continents, but the brain systems underlying spatial cognition are usually investigated only in small-scale environments. Do the same brain systems represent and process larger spaces? Here we asked subjects to compare distances between real-world items at six different spatial scales (room, building, neighborhood, city, country, continent) under functional MRI. Cortical activity showed a gradual progression from small to large scale processing, along three gradients extending anteriorly from the parahippocampal place area (PPA), retrosplenial complex (RSC) and occipital place area (OPA), and along the hippocampus posterior-anterior axis.

A structured graduated protocol with heat denatured eggs in the treatment of egg allergy.

Background: Most children with egg allergy (EA) can tolerate extensively heated and baked egg (EHBE). Consumption of EHBE may promote faster resolution of EA; however, no consensus exists as to the required amounts and treatment protocols.

Objective: To evaluate the efficacy and safety of a structured graduated exposure protocol (SGEP) with EHBE in promoting tolerance to eggs in EA children under 2 years of age.

Autosomal recessive diseases among the Israeli Arabs.

The Israeli population mainly includes Jews, Muslim and Christian Arabs, and Druze. Data on genetic diseases present in the population have been systematically collected and are available online in the Israeli national genetic database. Among the Israeli Arabs in December 31 2018, the database included molecular data on six diseases relatively frequent in the whole population: thalassemia, familial Mediterranean fever (FMF), cystic fibrosis, deafness, phenylketonuria or congenital adrenal hyperplasia as well as data on 632 autosomal recessive diseases among Muslim Israeli Arabs, 52 among the Christian Arabs and 79 among Druze.

Impact of Stressful Events on Motivations, Self-Efficacy, and Development of Post-Traumatic Symptoms among Youth Volunteers in Emergency Medical Services.

During the last decades, Israeli emergency medical services (EMS) personnel has been exposed to different potentially traumatic events, including mass terror attacks. The aims of the present study were to identify how potentially traumatic events affect young volunteers in their motivation to volunteer and their perceived self-efficacy while being at risk of developing post-traumatic symptoms. The final sample included 236 Magen David Adom (MDA, the "Israeli Red Cross") youth volunteers.

Self-Agency and Self-Ownership in Cognitive Mapping.

The concepts of agency of one's actions and ownership of one's experience have proved useful in relating body representations to bodily consciousness. Here we apply these concepts to cognitive maps. Agency is defined as 'the sense that I am the one who is generating the experience represented on a cognitive map', while ownership is defined as 'the sense that I am the one who is undergoing an experience, represented on a cognitive map'.

Official communication of the SSC: Recommendations for future research in catheter-related arterial thrombosis in children.

Catheter-related arterial thrombosis (CAT) are increasingly recognized in infants and children. Insufficient data are available on the incidence, risk factors, treatment and outcome of these thrombotic events. This work provides consensus recommendations for future research on catheter-related arterial thrombosis in the paediatric population.

Socialized occupational medicine in Israel: past, present, and future.

Occupational health in Israel is unique as it was originally established as a socialized service which anchored in extensive legislation and is accessible to all employees and employers without copayment. We review historical processes and legal basis that led to current structure of public occupational medicine services in Israel. Some of these go back a century and others extend way back to biblical times.

Addition of high-dose methotrexate to standard treatment for patients with high-risk diffuse large B-cell lymphoma contributes to improved freedom from progression and survival but does not prevent central nervous system relapse.

Combination of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) is regarded as standard care for diffuse large B-cell lymphoma (DLBCL) and upfront intensification of therapy is still controversial. The current study aimed to dertermine whether the addition of high-dose methotrexate (HDMTX) affects long-term outcomes and could also prevent central nervous system (CNS) relapse. Medical records of 480 patients with DLBCL treated between 1994 and 2013 at Rambam and Hadassah medical centers in Israel were reviewed; 130 (27%) had received HDMTX.

Should we use Palivizumab immunoprophylaxis for infants against respiratory syncytial virus? - a cost-utility analysis.

Background: Passive immunization against RSV (Respiratory Syncytial Virus) is given in most western countries (including Israel) to infants of high risk groups such as premature babies, and infants with Congenital Heart Disease or Congenital Lung Disease. However, immunoprophylaxis costs are extremely high ($2800-$4200 per infant). Using cost-utility analysis criteria, we evaluate whether it is justified to expand, continue or restrict nationwide immunoprophylaxis using palivizumab of high risk infants against RSV.

The IJHPR's growing scientific impact.

The Israel Journal of Health Policy Research (IJHPR) was launched in 2012, with a mission that included fostering intensive intellectual interactions among health policy scholars in Israel and abroad. Now, as the journal approaches the end of its seventh year of publication, we can all be proud that this component of our mission is increasingly being realized.As of the end of November 2018, the Web of Science included 404 articles published by the IJHPR.

A 10-year update: national survey questionnaire of obstetric anesthesia units in Israel.

Background: This nationwide survey was conducted to provide data about the obstetric anesthesia services in Israeli labor and delivery units in 2016.

Methods: Prospective survey questionnaire was emailed to obstetric anesthesia unit directors/chairperson of all 25 labor and delivery services units within the jurisdiction of the Israeli Ministry of Health.

Results: The response rate was 100%.

Family history of venous thromboembolism in the paediatric population: The need for a standardized definition.

Unlabelled: Positive family history is known to be an independent risk factor for venous thromboembolic (VTE) that may or may not reflect an underlying hereditary disorder. However, there is no clear standardized definition of what constitutes a positive family history for VTE in children. We aimed to assess the current published definitions of positive family history as a risk factor for VTE in children and ascertain if any consensus exists.
