Background: Most dyspneic patients in internal medicine departments have co-morbidities that interfere with the clinical diagnosis. The role of brain natriuretic peptide (BNP) levels is well-established in the acute setting but not in hospitalized patients.

Objectives: To evaluate the additive value of BNP tests in patients with dyspnea admitted to medical wards who did not respond to initial treatment.

Methods: We searched the records of patients who were hospitalized in the department of internal medicine D at Sheba Medical Center during 2012 and were tested for BNP in the ward. Data collected included co-morbidity, medical treatments, diagnosis at presentation and discharge, lab results including BNP, re-hospitalization, and mortality at one year following hospitalization.

Results: BNP results were found for 169 patients. BNP was taken 1.7 ± 2.7 days after hospitalization. According to BNP levels, dividing the patients into tertiles revealed three equally distributed groups with a distinctive character. The higher tertile was associated with higher rates of cardiac co-morbidities, including heart failure, but not chronic obstructive pulmonary disease. Higher BNP levels were related to one-year re-hospitalization and mortality. In addition, higher BNP levels were associated with higher rates of in-admission diagnosis change.

Conclusions: BNP levels during hospitalization in internal medicine wards are significantly related to cardiac illness, the existence of heart failure, and patient prognosis. Thus, BNP can be a useful tool in managing dyspneic patients in this setting.

Background: Low back pain has been the leading cause for disability worldwide for several decades, and clinical guidelines for its management clearly emphasize a multifactorial approach. Yet, current guidelines are still not well implemented by clinicians.

Objectives: To explore the attitudes of family medicine residents regarding low back pain and to determine whether they positively correlate with their treatment approaches. To test if these attitudes can be affected by the Enhanced Transtheoretical Model Intervention (ETMI), a guideline-based workshop.

Methods: Participants completed an online questionnaire regarding their attitudes toward low back pain and clinical habits, after which they attended an online ETMI educational workshop. One month later all participants were asked to complete the questionnaire a second time. Statistical analysis was conducted to explore the attitudes of the residents and clinical approaches, as well as any associations between them, as well as possible differences pre- and post-intervention.

Results: The participants exhibited highly psychologically oriented attitudes. Correlations between the attitudes and treatment did not show consistent coherency. Results regarding the participants clinical approaches were revealed to have two distinct and opposed inclinations: biomedically and biopsychosocially. Last, results for the re-activation subscale were significantly higher post-intervention.

Conclusions: Family medicine residents seem to be highly psychologically oriented regarding low back pain; however, they do not necessarily treat their patients accordingly. Their clinical choices seem to follow two different approaches: guideline-consistent and non-guideline-consistent. An ETMI guideline-based workshop may sway their attitudes toward re-activation of patients. Further research is needed to determine whether similar results would arise in larger physician populations.

Background: Self-management, an active life routine, and adherence to physical activity are effective in the management of low back pain (LBP). However, delivering effective education and reassurance to patients can be a difficult for practitioners. The enhanced transtheoretical model intervention (ETMI) has shown to be successful and cost effective. The intervention focuses on educating practitioners to reassure patients, empower them to increase physical activity, and improve their self-efficacy.

Objectives: To assess whether ETMI can be implemented among primary care practitioners and to examine whether it reduces pain, disability, and fear avoidance as well as decreasing healthcare utilization. This protocol outlines the methodology for the implementation of ETMI through a hybrid implementation–effectiveness design.

Methods: Two qualitative and mixed-method studies provided a basis for an implementation prospective cohort study. Discussions are followed by a prospective cohort study with pre-and post-intervention measures as well as descriptions retrieving economic and therapeutic outcome data from the Maccabi Healthcare Services (MHS) databases. In addition, a fourth qualitative study was conducted at the midpoint of the implementation to evaluate the process by measuring the perceptions and practice of practitioners. The intervention group was 220 primary care practitioners and their patients (~n=10,000) from the central district of MHS. The control data was provided by other care districts with similar socioeconomic makeup (~n=40,000).

Conclusions: We evaluated the process and outcomes of the implementation of ETMI. We investigated the relationship between the care received (ETMI against treatment as usual) and healthcare utilization, costs, and patient-clinical outcomes.

Background: Over the past several years there has been a marked increase in the number of Israel Defense Forces (IDF) soldiers having hip arthroscopy based on magnetic resonance arthrography diagnosis of hip labral tears and/or impingement.

Objectives: To detail characteristics of soldiers who underwent hip arthroscopy and assess outcomes and rate of return to duty.

Methods: A retrospective chart review was conducted of all soldiers who underwent hip arthroscopy 2018 to 2020, and soldiers referred for hip arthroscopy during 2021. Demographic, medical, and military service data were collected from the computerized patient record.

Results: Our study comprised 117 soldiers (29% combatants, 24% females) who underwent hip arthroscopy, mean age 22 ± 3 years, range 18–42; 45% had physiotherapy before surgery; 31% were diagnosed during or within 3 months of having back pain and 20% had been referred for psychological assistance (not related to the hip pain); 15.4% had serious adverse events. The mean time to return to any duty (including clerical work) was 8.0 ± 0.6 months; 56% of the soldiers never returned to service and were discharged from the military. During the one-year follow-up, only 6% returned to their full pre-symptom activity.

Conclusions: The short-term results of IDF soldiers who underwent hip arthroscopy during the study period were much inferior to those reported among athletes. The lack of specificity of the diagnostic tools (history, examination, and imaging) used to determine whether surgery for hip pain is likely to be beneficial in this population may be contributing to over-diagnosis and over-treatment.

Background: Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection in immunocompromised patients. Clusters of PJP, especially among organ transplant recipients in clinic settings were described. Data regarding nosocomial PJP infection among inpatients are limited.

Objectives: To assess the magnitude and characteristics of inpatient healthcare-associated PJP infection (HCA-PJP) in HIV-negative patients.

Methods: A retrospective chart review of hospitalized PJP patients was performed to identify HCA-PJP. The study was performed at six medical centers in Israel from 2006 to 2016. HCA-PJP was defined as cases of hospital-onset or those with documented contact with a PJP patient. We reviewed and cross-matched temporal and spatial co-locations of patients. Clinical laboratory characteristics and outcomes were compared.

Results: Seventy-six cases of PJP were identified. Median age was 63.7 years; 64% men; 44% hematological malignancies; 18% inflammatory diseases; and 61% steroid usage. Thirty-two patients (42%) were defined as HCA-PJP: 18/32 (23.6%) were hospitalized at onset and 14/32 (18.4%) had a previous encounter with a PJP patient. Time from onset of symptoms to diagnosis was shorter in HCA-PJP vs. community-PJP (3.25 vs. 11.23 days, P = 0.009). In multivariate analysis, dyspnea at presentation (odds ratio [OR] 16.79, 95% confidence interval [95%CI] 1.78–157.95) and a tendency toward higher rate of ventilator support (72% vs. 52%, P = 0.07, OR 5.18, 95%CI 0.7–30.3) were independently associated with HCA-PJP, implying abrupt disease progression in HCA-PJP.

Conclusion: HCA-PJP was common. A high level of suspicion for PJP among selected patients with nosocomial respiratory infection is warranted. Isolation of PJP patients should be considered

Background: Pericardial biopsies are rarely performed during the diagnosis and management of pericardial diseases. The circumstances and clinical profile of patients undergoing pericardial biopsies are largely uncharacterized.



Objectives: To examine the circumstances in which pericardial biopsies are obtained and to evaluate their diagnostic yield.



Methods: We studied a total of 100 cases (71% males, mean age 60.8 years, range 8.1–84.5 years) of surgically resected pericardium specimens obtained from 2000 to 2015 at Sheba Medical Center, the largest medical center in Israel. Patients were classified into groups according to four major histological etiologies: idiopathic pericarditis, constrictive pericarditis, malignant pericarditis, and post-cardiac injury syndrome (PCIS). The clinical history and course, laboratory, echocardiography, and histological results were reviewed retrospectively.



Results: Causes of pericarditis according to histological definitions included idiopathic pericarditis (29%), constrictive pericarditis (29%), PCIS (9%), and malignant pericarditis (26%). Overall sensitivity of the pericardial biopsy in patients with malignancy was 57.7%. During the study period, we found a trend toward an increased number of biopsies due to constrictive pericarditis and PCIS, along with a decrease in the number of biopsies performed in patients with malignant or idiopathic pericarditis. The diagnosis following biopsy did not change for any of the patients.



Conclusions: Our findings suggest a low diagnostic yield from pericardial biopsies, especially in malignant pericarditis. This conclusion, along with novel therapies, resulted in the infrequent use of pericardial biopsy in recent years.

Background: Antibiotic treatment of Clostridium difficile infection (CDI) has a high failure rate. Fecal microbiota transplantation (FMT) has proven very effective in treating these recurrences. 

Objectives: To determine which method of fecal microbiota transplantation (upper or lower gastrointestinal) and which type of donor (a relative or unrelated) is superior.

Methods: This is a retrospective analysis of treatment protocols and outcomes in 22 patients with refractory or recurrent CDI who underwent FMT at two Israeli facilities. Each center used a different donor type, stool preparation and method of delivery. The Tel Aviv Sourasky Medical Center used unrelated fecal donors and frozen stool samples and delivered them primarily (92%) via the lower gastrointestinal (GI) tract. Shaare Zedek Medical Center used fresh donor stool of relatives and delivered them primarily (90%) via the upper GI tract.

Results: FMT had an overall 2 month cure rate of 89%. Patients treated with FMT that was executed through the lower GI tract recovered faster from the infection (1.6 ± 1.08 vs. 2.4 ± 1 days for the upper tract, P = 0.03). The results also showed that patients who received lower GI tract FMTs were more likely to be cured of CDI (100% vs. 75% for upper tract FMTs, P = 0.16). Five patients (22%) died of CDI/FMT-unrelated causes and two (10%) died of CDI/FMT-related causes during the study period.

Conclusions: Lower GI tract FMT is a safe and effective treatment for refractory and recurrent CDI, and yields quicker results than upper GI tract FMT.

Background: Despite the large volume of evidence on the management of retained products of conception (RPOC), there are virtually no data regarding the optimal time frame of surgical intervention in case of RPOC.

Objectives: To examine whether the time interval between spontaneous vaginal delivery or pregnancy termination and the uterine evacuation due to pathologically confirmed RPOC influences the reproductive outcome.

Methods: We retrospectively reviewed all the records of women who were admitted to our department due to pathologically confirmed RPOC following either spontaneous vaginal delivery or pregnancy termination between January 2000 and December 2010. Based on the median time from delivery or pregnancy termination until the operative intervention in the study group, patients were stratified into two groups: early intervention (< 3 weeks) and late intervention (> 3 weeks). Reproductive outcomes were compared between the two study groups. 

Results: Reproductive outcomes were analyzed in 172 patients with pathologically confirmed RPOC. Of them, 95 (55.2%) were included in the early intervention group and 77 (44.8%) in the late intervention group. There were no significant differences in the conception rate, mean time to conception, and the occurrence rate of a new infertility problem in women with early surgical intervention compared to those with late surgical intervention (P > 0.05). Furthermore, there was no significant difference between the groups in the pregnancy outcomes following RPOC. 

Conclusions: Early surgical intervention in women with pathologically confirmed RPOC following spontaneous vaginal delivery or pregnancy termination yields the same reproductive outcomes as late surgical intervention.

Background: The association between antiphospholipid antibodies (aPL) and multiple sclerosis (MS) has been suggested previously, but prior studies provided contradicting findings. 

Objectives: To characterize the expression profile of eight classic and non-classic aPL in patients diagnosed with MS.

Methods: Using the BioPlex™ 2200 immunoassay, we measured the levels of serum immunoglobulin (Ig)M and IgG isotypes of three classic aPL and five non-classic aPL in 98 subjects with MS and 237 healthy controls. 

Results: Three non-classic aPL were significantly more prevalent among MS patients in comparison to the control group. These antibodies included IgM and IgG against phosphatidylserine-β2GPI (PS-B2), IgG prothrombin complex (PT-PT) and IgM prothrombin (PT). The positive results according to Bonferroni correction are PS-B2 IgG and PT-PT IgG. The remaining aPL profiles did not differ significantly between the two groups.

Conclusions: An association between certain non-classic aPL and MS has been established. The specific role of these autoantibodies in the pathogenesis of the condition remains uncertain.

Background: Mycetoma is a chronic and destructive infection caused by either fungus or bacteria. Mycetoma has a characteristic clinical presentation of a triad of tumor-like swelling, draining sinuses, and macroscopic grains. Mycetoma infection is extremely rare in Israel; however, in view of the recent immigration from mycetoma-hyperendemic regions of Africa to Israel, physicians in Israel may encounter this infection.

Objectives: To present two cases of mycetoma caused by Madurella mycatomatis in immigrants from endemic regions in Sudan treated at our hospital, and review the current literature. 

Conclusions: Health care professionals in Israel should suspect mycetoma in patients from endemic countries who present with tumor-like swelling especially in the lower extremity. Health care workers should be able to recognize mycetoma and provide the optimal treatment before the lesion progresses to an advanced and disabling disease.

Fungal diseases affect a large proportion of the population, ranging in severity from mild superficial infections to life-threatening invasive diseases. Estimates of disease burden are needed to inform public health policies. We estimated the incidence of fungal diseases in Israel based on published surveillance data and risk-based calculations using previously established models. Deaths associated with fungal diseases were estimated from local surveillance data (candidemia) and published reports (invasive aspergillosis). Candidemia was estimated in 649 persons/year and invasive aspergillosis in 254 persons/year; the associated mortality was 2.75 and 0.96 per 100,000 population/year, respectively. Recurrent Candida vulvovaginitis occurs in 130,440 women annually. National incidence rates of cryptococcosis, pneumocystis pneumonia and mucormycosis could not be reliably estimated. Single-center data-derived estimates yielded 24, 26 and 20 cases/year, respectively. Allergic bronchopulmonary aspergillosis, asthma with fungal sensitization and allergic fungal sinusitis affect 8297 (range 2323–11,615), 14,372 (14,372–17,965) and 39,922 (15,969–183,643) persons, respectively. In Israel, candidemia and invasive aspergillosis rank high among infection-related causes of mortality. Allergic fungal diseases cause chronic or recurrent symptoms in a large population and may contribute to asthma-related hospitalization and death. These general estimates should serve as a primer for future efforts to study fungal epidemiology.
