Background: Survivors of critical illness are at increased risk of long-term impairments, referred to as post-intensive care unit (ICU) syndrome (PICS). Post-traumatic stress disorder (PTSD) is common among ICU survivors with reported rates of up to 27%. The prevalence of PTSD among Israeli ICU survivors has not been reported to date.

Objectives: To evaluate the prevalence of new onset PTSD diagnosed in a post-ICU clinic at a tertiary center in Israel.

Methods: We conducted a retrospective, single center, cohort study. Data were collected from medical records of all patients who visited the Tel Aviv Sourasky Medical Center post-ICU clinic between October 2017 and June 2020. New onset PTSD was defined as PTSD diagnosed by a certified board psychiatrist during the post-ICU clinic visit. Data were analyzed using descriptive statistics.

Results: Overall, 39 patients (mean age 51 ± 17 years, 15/39 females [38%]) attended the post-ICU clinic during the study period. They were evaluated 82 ± 57 days after hospital discharge. After excluding 7 patients due to missing proper psychiatric analysis, 32 patients remained eligible for the primary analysis. New PTSD was diagnosed in one patient (3%).

Conclusions: We found lower incidence of PTSD in our cohort when compared to existing literature. Possible explanations include different diagnostic tools and low risk factors rate. Unique national, cultural, and/or religious perspectives might have contributed to the observed low PTSD rate. Further research in larger study populations is required to establish the prevalence of PTSD among Israeli ICU survivors.

On Saturday, 7 October 2023, the Jewish holiday of Simchat Torah, our entire country woke to a reality of the worst terror attacks it has ever known, despite its long history of wars and terror. These horrific attacks included killing and burning babies, children, women, men, and the elderly; raping women; beheading babies; destroying settlements; and kidnapping more than 240 civilians and soldiers. The severe traumatic events created different circles of those exposed to trauma. In each group, the intensity of the trauma was different and had different characteristics.

The interplay between post-traumatic stress disorder (PTSD) and autoimmunity is well known. One of the contributors leading to immune disorders is autonomic dysregulation, which is characterized by attenuated parasympathetic and elevated sympathetic systems. In this review, we described evidence regarding the relationship between stress, PTSD, autonomic dysfunction, and autoimmunity. Stress is a physiological response, which is functional for our being. The implication of dysfunction in stress response may be a cause of disease development. We described the fundamental role of the pathological high levels of stress in PTSD as a mediator factor that contributes to autonomic dysfunction, which as a result may lead to autoimmunity. Systemic lupus erythematosus, rheumatoid arthritis, and type 1 diabetes are some of the autoimmune diseases PTSD patients are at higher risk of developing. Notably, some autoimmune diseases are shown to increase the susceptibility to develop PTSD, which may indicate a bidirectional influence. In addition, we elaborated on stress as a major component in both fibromyalgia and PTSD, as there are overlaps between the pathogenesis of fibromyalgia and PTSD. Underlying chronic low-grade inflammation, which characterizes PTSD patients, may be a potential target and biomarker in treating PTSD patients. We believe that chronic low-grade inflammation, high concentrations of cytokines, and other inflammatory biomarkers, which characterize PTSD patients, may be potential targets and biomarkers in the treatment of PTSD patients and part of the PTSD diagnostic criteria.

Background: A history of childhood sexual abuse (CSA) has been linked to a variety of physical and psychiatric illnesses, including ischemic heart disease and post-traumatic stress disorder (PTSD).

Objectives: To determine the prevalence of past CSA and re-traumatization among hospital psychiatric consultations and to determine whether a CSA group in a hospital setting shared characteristics with community samples described in the literature.

Methods: We divided 228 consecutive psychiatric consultations into two groups. One group comprised patients with a past history of CSA while the other group had no such history. Both groups were further divided into a subgroup that presented with features of re-traumatization.

Results: In the cohort, 38% described a history of CSA. Twenty patients were identified as presenting with features of re-traumatization. There were significant differences between the two groups. The patients with a history of CSA were more likely to have arrived at the emergency department (ED) during the preceding 12 months with a diagnosis of PTSD, personality disorder, and substance use disorder. There was a greater proportion of patients in the CSA group who had grown up in an ultra-Orthodox Jewish household and who currently identified as being secular.

Conclusions: The characteristics of the patients with past CSA in this study are similar to community-based samples, except for a significant gender difference. To the best of our knowledge, this study is the first to investigate CSA history during hospital ED psychiatric consultations. A history of CSA should be considered during psychiatric consultations in a general hospital ED admission.

Background: Previously described as a subcategory of obsessive compulsive disorder (OCD), hoarding disorder was added to the fifth Diagnostic and Statistical Manual of Mental Disorders (DSM-V) as a stand-alone diagnosis for the first time. The first formal research in the 1990s surprisingly found no connection between material deprivation early in life and hoarding; however, later studies linked early traumatic life experiences with hoarding. Subsequent familial studies demonstrated a genetic predisposition for hoarding. Emerging evidence suggests a link between a post-traumatic stress disorder (PTSD) and hoarding in Jewish Holocaust survivors.

Objectives: To evaluate the literature on PTSD among Jewish Holocaust survivors for associations between PTSD and hoarding.

Methods: A systematic search of selected databases, including PubMed, Google Scholar, NCBI, Psych Info, and EBSCO Host was conducted from 1 March 2017 to 15 July 2018 using the following search terms: hoarding, hoarding disorder, obsessive compulsive disorder, OCD, compulsive hoarding, Jewish Holocaust survivors, Shoa, post-traumatic stress disorder, and PTSD. Inclusion criteria included peer reviewed research published on adults in English since 1990. Because no publications linking hoarding and PTSD in Jewish Holocaust survivors were found, references in retained papers were also searched for any relevant published work.

Results: Seven articles linking PTSD and hoarding were identified for this review. However, no articles were found linking PTSD and hoarding in Jewish Holocaust survivors.

Conclusions: A relationship between PTSD and hoarding in Jewish Holocaust survivors is conceivable and should be explored to effectively diagnose and care for affected individuals.

Objectives: To evaluate health utilization patterns in two primary care clinics in southern Israel: one under continuous attacks of Qassam rockets as compared with a similar clinic not under a rocket threat.

Methods: We conducted a retrospective cross-sectional study in two primary care clinics in southern Israel, with 11,630 persons listed in the two clinics during the entire study period. The primary outcome measures were total annual number of visits per person to the clinic and for specific diagnoses, and the number of drug prescriptions issued, emergency room (ER) visits, hospitalization days, cardiac catheterizations and coronary bypass surgeries.

Results: In both clinics there was an increase over time in the mean annual number of visits per person. During the years of severe attacks there was an increase in visits with a chief complaint of depression and anxiety and an increase in the number of anxiolytic prescriptions in the study clinic compared with the control. During the same period there was a decrease in the number of ER visits in the study clinic compared with the control.

Conclusions: The population under continuous life-threatening events showed more depression and anxiety problems. Under severe bombardment, the residents prefer not to leave home, unless necessary.

Background: A major psychological sequel of terrorist attacks is post-traumatic stress disorder. The relation between certain psychological factors specific to terrorist attacks (e.g., perceived control attributed to oneself/to the military, anticipated duration of terrorism) and PTSD[1] symptoms have not been examined.

Objective: To examine the prevalence, correlates and moderators of PTSD-like symptoms following terrorist attacks in Israel.

Methods: Soon after a long wave of terrorist attacks in Israel in 2002, a convenience sample of 149 Israelis from five cities was assessed for terrorist attack exposure, perceived control, control attributed to the government/military, anticipated duration of the terrorism wave (predictability), and frequency of listening to the news. PTSD-like symptoms were assessed with a brief self-report scale.

Results: We found that 15.4% of the sample was directly exposed to a terrorist attack and 36.5% knew someone close who had been exposed to an attack. “Clinically significant” PTSD-like symptoms were reported by 10.1% of the sample. Correlates of PTSD-like symptoms were: perceived control in men, government control, and education in women (all inversely correlated to PTSD symptoms), and news-listening frequency in women (positively correlated to PTSD symptoms). PTSD-like symptoms were attenuated by the ability to predict the duration of the terrorism wave only in citizens exposed to an attack, and by perceived government control only among citizens listening infrequently to the news.

Conclusions: This study revealed that approximately 10% of Israelis in our sample had relatively frequent PTSD-like symptoms. Correlates of PTSD-like symptoms differed between men and women, and moderator effects were found. These findings reveal additional moderators that may have implications for treating PTSD following terrorist attacks.

Background: Articular cartilage is incapable of undergoing self-repair since chondrocytes lose their mitotic ability as early as the first year of life. Defects in articular cartilage, especially in weight-bearing joints, will predictably deteriorate toward osteoarthritis.  No method has been found to prevent this deterioration. Drilling of the subchondral bone can lead to fibrocartilage formation and temporary repair that slowly degrades. Animal experiments indicate that introducing proliferating chondrocytes such as cultured articular chondrocytes can reliably reconstruct joint defects.

Objectives: To describe our clinical experience in culturing and transplanting autologous chondrocytes. 

Methods: Biopsies were obtained from 10 patients, aged 18–45, undergoing a routine arthroscopy in which a cartilage defect was identified with indications for cartilage transplantation. The biopsies were further processed to establish chondrocyte cultures. ACT was performed in 8 of the 10 patients because of persistent symptoms for at least 2 months post-arthroscopy. All patients (6 men and 2 women) had a grade IV cartilage defect in the medial or lateral femoral condyle, and three had a defect in the trochlear region as well. Biopsies were removed from the lateral rim of the superior aspect of the femur, and cells were cultured in a clean room. Following a 2 order of magnitude expansion, cells were implanted under a periosteal flap.

Results: The eight patients implanted with autologous cells were followed for 6 months to 5 years (average 1 year). Complaints of giving-way, effusion and joint locking resolved in all patients, and pain as assessed by the visual analogue score was reduced by an average of 50%. Follow-up magnetic resonance imaging studies in all patients revealed that the defects were filled with tissue having similar signal characteristics to cartilage.

Conclusions: Chondrocyte implantation is a procedure capable of restoring normal articular cartilage in cases with isolated joint defects. Pain can be predictably reduced, while joint locking and effusion are eliminated. The effect on osteoarthritis progression in humans has not yet been elucidated.

Background: Spectral analysis of heart rate variability has been shown to be a reliable non-invasive test for quantitative assessment of cardiovascular autonomic regulatory responses, providing a window reflecting the interaction of sympathetic and parasympathetic tone. Alterations in autonomic function are associated with a variety of physiologic and pathophysiologic processes and may contribute substantially to morbidity and mortality. Our previous study shows that patients with post-traumatic stress disorder have significantly lower HRV compared to controls, reflecting a basal autonomic state characterized by increased sympathetic and decreased parasympathetic tone.

Objectives: To apply this tool to PTSD patients treated with selective serotonin re-uptake inhibitors in order to assess the impact of such treatment on the autonomic dysregulation characterizing these patients.

Methods: Standardized heart rate analysis was carried out in nine PTSD patients treated with SSRI agents and compared to that in a matched control group of nine healthy volunteers and in nine untreated PTSD patients, based on a 15 minute resting electrocardiogram.

Results: Our preliminary results show that the HRV parameters indicating autonomic dysregulation, which characterize PTSD patients at rest, are normalized in responding patients by use of SSRIs. Neither the clinical implications of these findings nor their physiological mechanisms are clear at present, although we presume that they reflect a central effect, since the peripheral autonomic effects of SSRIs are relatively negligible.

Background: In our experience, secondary enuresis nocturna is a common complaint among children after a motor vehicle accident.  However, as these children are often brought for examination as part of an insurance compensation claim, this complaint is not always reliable.

Objective: To describe a series of children in whom secondary enuresis occurred after a motor vehicle accident.

Methods and Results: Five children were brought to our clinic for evaluation of secondary nocturnal enuresis. Review of past history revealed a car accident preceding the onset of the enuresis. All but one had additional behavioral symptoms typical of post-traumatic stress disorder. Four children had evidence of head trauma, and one had psychological but no physical trauma. 

Conclusions: Nocturnal enuresis can occur after a motor vehicle accident due either to purely psychological trauma or organic head trauma. While nocturnal enuresis is generally attributed to organic causes, psychological mechanisms also play a significant role.
