Background: There are conflicting data on the significance of hyperuricemia or hyperuricosuria in urolithiasis formation and on the need for medical treatment.

Objectives: To assess the significance of hyperuricemia or hyperuricosuria in urolithiasis formation, particularly when hyperuricemia occurs with normal uricosuria.

Methods: The electronic medical records of patients treated in Haifa and the Western Galilee district of Clalit Health Services, Israel, were retrospectively screened for diagnosis of nephrolithiasis or renal or urinary tract/bladder calculi between February 2014 and April 2019. The diagnosis was confirmed by ultrasonography or computed tomography. The study group included patients with one of these diagnoses. Patients in the control group did not have these diagnoses. The inclusion criterion for all patients was the presence of both serum and urinary uric acid levels.

Results: The study group included 359 patients and the control group 267. After adjustment by logistic regression, we found no significant differences in the prevalence of hyperuricosuria in the study group (14.8%) compared to the control group (9.7%), odds ratio (OR) 1.54 (95% confidence interval [95%CI] 0.74–3.2, P = 0.245). No significant differences between the groups were observed for hyperuricemia prevalence (45.4% vs. 55.1%, respectively, OR 0.82, 95%CI 0.54–1.25, P = 0.355), nor among those without hyperuricosuria (OR 0.83, 95%CI 0.52–1.33, P = 0.438) and after propensity score matching (OR 0.93, 95%CI 0.66–1.3, P = 0.655).

Conclusions: There were no significant differences in hyperuricemia or hyperuricosuria between the two groups of patients or in hyperuricemia among participants without hyperuricosuria.

The ancient, Biblical, holy Ten Commandments were presented to humanity to serve as guidelines for relationships between individuals and the deity they worship as well as a benchmark for living in civilized communities, irrespective of religious affiliation. The commandments are also embedded in medical education taught to medical students and other health professions throughout the world. Thus, the Ten Commandments are embedded in the medical communications curriculum at Adelson School of Medicine, Ariel University, Ariel, Israel. Unfortunately, most of these commandments were desecrated during the violent, hostile, merciless, and ruthless attack inflicted by the Hamas terror organization on villages, rural communities, and cities in southern Israel on 7 October 2023. We define the Ten Commandments in terms of medical education and describe their desecration by Hamas terrorists before and during the Iron Swords war.

Background: Social distancing, implemented to decrease the spread of coronavirus disease-2019 (COVID-19), forced major changes in medical practices, including an abrupt transition from face-to-face to remote patient care. Pre-clinical medical studies were concomitantly switched to electronic distance learning.

Objectives: To explore potential implications of COVID-19 on future pre-clinical medical studies.

Methods: We examined responses of pre-clinical medical students to the remote electronic learning in terms of quality of and satisfaction with teaching and technical support, attendance to classes, and the desire to continue electronic learning in the post-epidemic era. A survey of responses from first-year students at the Adelson School of Medicine was conducted. To optimize the reliability of the survey, a single research assistant conducted telephone interviews with each student, using a structured questionnaire concerning aspects of participation and satisfaction with teaching and with technical components of the remote electronic learning.

Results: With 100% response rate, the students reported high satisfaction with the electronic learning regarding its quality, online interactions, instructions given, technical assistance, and availability of recording for future studies. Most of the students (68.6%) noted a preference to continue < 90% of the learning online in the post-outbreak era. A high level of overall satisfaction and a low rate of technical problems during electronic learning were significantly correlated with the desire to continue online learning (P < 0.01).

Conclusions: The high satisfaction and the positive experience with the electronic distance learning imposed by the COVID-19 epidemic implied a successful transition and might induce future changes in pre-clinical medical studies.

Background: Thymectomy is a reliable surgical method for treating patients with myasthenia gravis (MG) and benign tumors of the thymus. Despite the advantages of minimally invasive surgical approaches for resection of thymic neoplasms, there are still controversies regarding the superiority of one type of surgery over another.

Objectives: To report the results of our initial Israeli experience with robotic thymectomy in 22 patients with MG and suspected benign thymic tumors.

Methods: We retrospectively analyzed 22 patients (10 men, 12 women) who underwent robotic thymectomy by a left-sided (16) or right-sided approach (6) using the da Vinci robotic system at Assaf Harofeh Medical Center. Seven patients were diagnosed with MG before surgery and 14 had suspected benign thymic neoplasms.

Results: Average operative time was 90 minutes. There were no deaths or intraoperative complications. Postoperative complications occurred in two patients (dyspnea and pleural effusion). Median blood loss was 12.3 cc (range 5–35 cc), median hospital stay 2.9 days (range 2–5 days), and mean weight of resected thymus 32.1 grams. Seven patients had thymic hyperplasia, six a lipothymoma, one a thymic cyst. Seven each had thymomas in different stages and one had a cavernous hemangioma.

Conclusions: Robotic thymectomy is a safe, technically effective surgical method for resection of thymic neoplasms. The advantages of this technique are safety, short hospitalization period, little blood loss, and low complications. We have included this surgical procedure in our thoracic surgery residency program and recommend a learning curve program of 10 to 12 procedures during residency.

Background: Metal-on-metal total hip prostheses (MoM-THR) have been shown to produce hypersensitivity reactions and fluid collection (pseudotumor) by the hip as well as high blood metal ions levels (BMILs).

Objectives: To evaluate the magnetic resonance imaging (MRI) signal-to-noise ratio (S/N) in selected body tissues around the hip of patients who underwent MoM hip replacement and to correlate to BMILs.

Methods: Sixty-one MRI hip examinations in 54 post-MoM-THR patients (18 males, 36 females, mean age 65 years) were retrospectively evaluated independently by two readers. The mean S/N ratio in a region of interest was calculated for periprosthetic pseudotumor collection (PPC), the bladder, fat, and muscle on axial T1w, FSE-T2w, and short tau inversion recovery (STIR) sequences on the same location. BMILs were retrieved from patient files.

Results: PPC was detected in 32 patients (52%) with an average volume of 82.48 mm³. BMIL did not correlate with the presence of PPCs but positively correlated with the PPC's volume. A trend for positive correlation was found between BMILs and S/N levels of STIR images for muscle and bladder as well as for PPC and cobalt levels. A trend for correlation was also seen between BMIL with PPC's T1 w S/N.

Conclusions: Alteration of MRI S/N for different hip tissues showed a tendency for correlation with BMILs, possibly suggesting that metal deposition occurs in the PPC as well as in the surrounding tissues and bladder.

Background: Androgen deprivation therapy (ADT) added to radiation therapy (RT) in intermediate to high risk prostate cancer negatively impacts quality of life. 

Objectives: To compare health-related quality of life (HR-QOL) in patients receiving combined RT with and without ADT 

Methods: The study population comprised patients treated with definitive RT for prostate cancer who completed the Expanded Prostate Cancer Index Composite-26 form between 3 and 24 months after completing RT. Covariance and a stepwise backward logistic regression model was used. 

Results: Data were available for 143 patients who received RT+ADT and 70 who received RT alone. The sexual function and hormonal vitality scores of patients receiving RT+ADT were significantly lower than those receiving RT alone (P < 0.0001). Patients with only compulsory school education had significantly lower sexual function scores than patients with university level education (P ≤ 0.005). Patients with depression had significantly lower hormonal vitality scores than those without depression (P ≤ 0.0001). 

Conclusions: The addition of ADT to RT is responsible for decrements in quality of life in the sexual and hormonal vitality domains, which is further compounded by lack of education and depression. This underlines the need to improve education, identify and treat depression, and develop strategies to improve the quality of life of patients receiving combination therapy. 

 

Background: Glioblastoma multiforme (GBM) is an ultimately fatal disease that affects patients of all ages. Elderly patients (65 years and older) constitute a special subgroup of patients characterized by a worse prognosis and frequent comorbidities.

Objectives: To assess the efficacy of different treatment modalities in terms of survival in elderly patients with GBM¹.

Methods: Using retrospective analysis, we extracted, anonymized and analyzed the files of 74 deceased patients (aged 65 or older) treated for GBM in a single institution.

Results: Mean survival time was 8.97 months and median survival time 7.68 months. Patients who underwent tumor resection had a mean survival of 11.83 months, as compared to patients who underwent no surgical intervention or only biopsy and had a mean survival of 5.22 months (P < 0.0001). Patients who underwent full radiation treatment had a mean survival of 11.31 months, compared to patients who received only partial radiotherapy or none at all and had a mean survival of 4.09 months (P < 0.0001). Patients who underwent chemotherapy had a mean survival 12.4 months, compared to patients who did not receive any chemotherapy and had a mean survival of 5.89 months (P < 0.001).

Conclusions: Age alone should not be a factor in the decision on which treatment should be given. Treatment should be individualized to match the patient’s overall condition and his or wishes, while taking into consideration the better overall prognosis expected with aggressive treatment.
 

Background: Benign paroxysmal positional vertigo is a common and treatable vestibular disorder characterized by attacks of positional vertigo. Although elderly patients often complain about unsteadiness, the symptom of positional vertigo is seldom reported. Several studies on BPPV[1] in the elderly reveal a low success rate in the treatment of this entity.

Objectives: To assess the clinical characteristics and treatment outcome of BPPV in elderly patients and to compare them with those of the general population treated at our dizziness clinic.

Methods: We reviewed the medical records of 23 patients above age 75 who were treated at our dizziness clinic for BPPV during the years 1998–2004. Their clinical data, BPPV characteristics and treatment outcome were compared with the data of 30 consecutive BPPV patients who represented the general population.

Results: No differences in gender distribution, duration of BPPV, treatment responsiveness or recurrence rate were found between elderly patients as compared to the general population. The duration of the last attack of positional vertigo was found to be longer in the elderly, probably due to the delay in recognition of symptoms and accessibility of a dizziness clinic.

Conclusions: Our study shows that BPPV characteristics and treatment effectiveness, as measured by negative Dix-Hallpike maneuver, are not age-dependent and there is no need for a special approach or cautiousness in prognosis prediction. It is important to search actively for this condition since treatment leads to amelioration of unsteadiness and improved well-being in these patients.

Background: Burnout is a professional occupational disease that puts both physicians and patients at risk. Triggered by the increase in burnout levels among physicians, the European Forum of Medical Associations and the World Health Organization issued a statement in March 2003 expressing serious concerns about the situation, urging all national medical associations to increase awareness of the problem, monitor it and study its causes in order to develop preventive strategies.

Objectives: To compare burnout levels in two separate samples of primary care physicians measured in the mid-1990s, with burnout levels in a similar but small and independent sample, assessed in 2001; and to outline the theoretical bases of burnout.

Methods: Altogether, 508 primary care physicians employed by Clalit Health Services responded anonymously to a self-report questionnaire. The samples were not representative and included family physicians, pediatricians and clinic directors.

Results: Burnout levels were significantly higher in the 2001 sample than in the mid-1990s samples, especially among clinic directors.

Conclusions: Despite methodologic limitations of the study, the findings suggest that burnout levels may be increasing among primary care physicians in Israel. This may be due to substantial increases in workload and role conflicts, following implementation of the Health Insurance Law and Patients’ Rights Act. Because these findings are consistent with the trend in Europe, this situation cannot be ignored, and systematic studies of burnout among all medical specialties should be carried out to uncover current sources of the syndrome and to devise measures of prevention and treatment.
 

Background: Dizziness and vertigo can be a complaint in various psychiatric conditions, where it usually constitutes only one of the features of the syndrome. Lately, a somatoform disorder characterized by almost mono-symptomatic dizziness and unsteadiness has been described. Since phobic postural vertigo usually presents without anxiety or other psychological symptomatology, patients with this condition seek help at neurologic and otolaryngologic clinics where they are often misdiagnosed as suffering from organic vertigo.

Objectives: To present the clinical features of 55 consecutive patients diagnosed with phobic postural vertigo at our clinic during 1998–2002.

Methods: We conducted a retrospective review of patients’ medical records and report two typical cases as illustration.

Results: The patients presented with complaints of unsteadiness with or without dizziness, and attacks of sudden veering that caused them to grasp for support. Accompanying anxiety was admitted by only 5% and vegetative symptoms were reported in 18%. In 16% the symptoms resulted in avoidance behavior. A stressful life event or an unrelated somatic disease triggered the onset of PPV[1] in 35% of patients, whereas a vestibular insult preceded the symptoms in 13%. The mean duration of symptoms was 26.7 ± 39.1 months (range 0.5–20 years). In 72% of patients the symptoms resolved after the psychological mechanism of their symptoms were explained to them; 24% improved with antidepressant treatment (selective serotonin reuptake inhibitors or tricyclic antidepressants), and only in 4% did the symptoms persist.

Conclusions: Since PPV is a frequently encountered diagnosis at some specialized dizziness clinics, familiarity with this entity resulting in early diagnosis can avoid unnecessary examinations and lead to effective treatment.

Objectives: To assess the structure and the positive and negative job components of family physicians in Israel, as well as the effect of these components on their satisfaction with their work.

Methods: A questionnaire was sent to a random selection of members of the Israel Society of Family Physicians (n=225).

Results: Altogether 183 questionnaires were returned. Specialist family doctors, practice medical directors and salaried doctors were involved in more activities than non-specialist doctors, trainees and self-employed doctors. Overall satisfaction was highest for specialists and lowest for non-specialists. Work overload, insufficient resources and abundant paperwork were most frequently cited as negative work components. The opportunity to utilize medical knowledge, challenging work and work variety scored highest as positive components.

Conclusions: The more professionally active physicians were also the more satisfied. Clinical work and teaching provided the most satisfaction, while administrative work and lack of time were the main causes of dissatisfaction.
