Background: Local anesthetics are used in various sites and mechanisms to maximize perioperative analgesia and reduce opioid use and side effects. Pain management in the bariatric setting is challenging and the efficacy of local anesthetics intraoperatively is under current evaluation.

Objectives: To determine the safety and efficacy of a new intra-abdominal anesthetic technique performed during laparoscopic bariatric operations: visceral block.

Methods: During this prospective randomized double-blinded pilot study, 16 patients undergoing bariatric surgery were treated with the injection of ropivacaine to the anterior esophagogastric junction fat, and 15 were injected with saline as control.

Results: The procedure was shown to be safe, and no adverse events nor side effects were encountered. A non-statistically significant trend toward the use of a non-opioid analgesia was documented during the first postoperative hours.

Conclusions: Visceral block is a safe and feasible intraoperative procedure. A trend toward its efficacy warrants future larger scale studies.

The prevalence of difficult-to-treat rheumatoid arthritis (D2T RA) varies between 5% and 25%, with females comprising the majority of patients and no difference in patient age between D2T and non-D2T RA cohorts. While several attempts to subclassify D2T RA patients into defined subgroups have been tried, the inclusion of an individual D2T RA patient to one of the predefined subgroups can be difficult or impossible as multiple factors are usually involved in the mechanisms of rheumatoid arthritis (RA) refractoriness, with the complex interplay of inflammatory, structural, social, and psychological factors being unique for each patient. More severe disease at presentation, including seropositivity and early erosion formation, and insufficiently aggressive initial treatment can both contribute to the eventual development of D2T RA. No single test or study can replace the holistic clinical approach to the diagnosis and understanding of the causation of D2T RA. Traditional in-depth clinical history and thorough clinical examination remain sine qua non in managing D2T RA patients. Multifaceted contributions of inflammatory and non-inflammatory components create the uniqueness of D2T RA and dictate a comprehensive approach to the management, including both pharmacologic and non-pharmacological therapeutic strategies. Mean annual total costs for D2T RA patients have been estimated as being about twice as high as that of patients with non-D2T RA.

Background: Data regarding the management of adnexal torsion (AT) during the coronavirus disease 2019 (COVID-19) pandemic are scarce.

Objectives: To study the effects of actions to limit the spread of COVID-19 on AT management.

Methods: We conducted a retrospective cohort study of all women who underwent laparoscopy for suspected AT between March 2011 and February 2021. We compared the COVID-19 pandemic period, (15 March 2020–2 August 2021, group A) to a parallel period (2019–2020, group B), and a 9-year period preceding the pandemic (March 2011–February 2020, group C).

Results: We performed 97 laparoscopies in group A, 82 in group B, and 635 in group C. The proportion of women presenting following in vitro fertilization treatment was lower (odds ratio [OR] 0.22, 95% confidence interval ]95%CI] (0.06–0.86), P < 0.023). Time from admission to decision to operate was shorter (2.7 vs. 3.9 hours, P = 0.028) in group A than group B. Time from admission to surgery was shorter (9.1 vs. 12.5 hours, P = 0.005) and the rate of surgically confirmed AT was lower (59 [60.8%] vs. 455 [71.7%], P = 0.030, OR 0.61, 95%CI 0.39–0.95) in group A than group C. Among surgically confirmed AT cases only, mean time from admission to decision was shorter in group A than group B (2.6 vs. 4.6 hours, P = 0.014).

Conclusions: We identified differences in time from admission to clinical decision and from admission to surgery among women with suspected AT during the COVID-19 pandemic.

A 90-year-old female with a medical history of untreated gout presented to the emergency department with acute low back pain. On physical examination, the area over the 4th lumbar spinous process was extremely tender. Serum C-reactive protein was 184 mg/L, and uric acid was 8.3 mg/dl.

Conventional [Figure 1A] and dual-energy computed tomography (DECT) [Figure 1B] studies of the lumbar spine showed multiple tophi-engulfing posterior vertebral structures of the involved vertebral unit, including the spinous and transverse processes and facet joints. This condition is schematically shown in Figure 1C with asterixis indicating tophi-induced erosion and osteolysis of the spinous process.

The patient was treated for a suspected acute gouty attack with prednisone and colchicine followed by allopurinol treatment with rapid and uneventful recovery.

Axial gout is an underdiagnosed and potentially curable cause of recurrent low back pain [1,2]. Referral to DECT should be considered in patients with uncontrolled gout and concurrent back pain.

Background: Intra-articular knee injections (IAKI) are commonly used for diagnostic and therapeutic purposes but may induce anxiety and fear. While existing literature has identified the variance between expected and actual pain levels in various medical procedures, this phenomenon remains unexplored in the context of IAKI.

Objectives: To describe the differences between anticipated and experienced pain recorded during IAKI.

Methods: The study cohort included 50 patients who underwent IAKI by an orthopedic specialist in an outpatient clinic. Patients recruited to the study recorded the anticipated and experienced pain, anxiety index, and factors influencing injection related fear.

Results: The study population (n=50) demonstrated a significant difference between the pain expected before the injection (mean Visual Analogue Scale [VAS] score 6.19) and the actual experienced (mean VAS score 2.07, P-value < 0.001). Significant differences between anticipated and experienced VAS scores were demonstrated for both females and males. There was a significant difference between males and females in terms of estimated VAS score. There was no significant difference between males and females in term of the experienced VAS score. The difference (delta) between expected and experienced pain differed significantly between sexes.

Conclusions: These findings emphasize the importance of educating patients about expected pain levels during IAKI. Presenting this quantified information may reassure patients that the procedure is not as painful as expected, which can potentially increase the compliance.

A 26-year-old female at 28 weeks of gestation with her fourth pregnancy presented with a 24-hour history of diffuse abdominal pain and distension. In addition, she had nausea, vomiting, and constipation. The pain did not respond to analgesics. She had poor prenatal care during her pregnancy. She had previously had three cesarean deliveries. The first cesarean delivery was due to non-progressive second stage of labor, the second was preterm due to abdominal pain and suspected uterine rupture, and the last was due to the previous cesarean deliveries. In her last previous pregnancy, she presented with recurrent milder abdominal pain, which resolved spontaneously.

On examination, she was afebrile, with normal blood pressure and heart rate. Her abdomen was distended, tympanic, and mildly tender to palpation with no tenderness on the cesarean scar and no peritoneal signs. Her laboratory testing was normal except for mild hypokalemia.

Background: Myalgic encephalomyelits/chronic fatigue syndrome (ME/CFS) is an acquired disease with symptoms of fatigue and pain. In pathogenesis, the induction of autoantibodies (AAB) against G-protein coupled receptors (GPCR), such as β-adrenergic receptors (β-AdR), has been suspected. GPCR-AAB correlate with symptom severity and autonomic dysfunction in ME/CFS.

Objectives: To describe symptoms and treatment of a patient presenting with infection-triggered ME/CFS demonstrating that levels of β-AdR-AAB underlie modulation over time, correlating with the severity of symptoms.

Methods: At T1 and T2, GPCR-AAB were measured and questionnaires assessing symptom severity were completed. TSHDS-IgM-AAB were tested, and SF density was analyzed via skin probe.

Results: At T2, elevated levels of β-AdR-AAB were found, corresponding with an aggravation of fatigue and pain symptoms. Elevated TSHDS-IgM-AAB were found, which corresponded with reduced fiber density from the skin probe.

Conclusions: The levels of β-AdR-AAB in post-infectious ME/CFS can be modulated. Future studies might target interventions to reduce these AAB.

Background: Fibromyalgia syndrome (FMS) is estimated to affect 2–4% of the general population. While FMS has some known environmental and genetic risk factors, the disorder has no clear etiology. A common coexisting disorder with FMS is small fiber neuropathy (SFN). High levels of serum immunoglobulin M (IgM) binding to trisulfated-heparin-disaccharide (TS-HDS) were recently found to be associated with SFN.

Objectives: To evaluate potential differences in anti-TS-HDS antibody titers in women with FMS compared to healthy controls.

Methods: In this cross-sectional study, we evaluated 51 female participants: 30 with a diagnosis of FMS and 21 healthy controls who had been recruited at the Zabludowicz Center for Autoimmune Diseases, Sheba Medical Center, Israel. All of the participants were older than 18 years of age. Anti-TS-HDS IgM levels were measured in their sera using the enzyme immunoassay technique.

Results: The mean anti-TS-HDS IgM levels were significantly lower in the FMS group, compared with the control group (7.7 ± 5 vs. 13.2 ± 8.6 U/ml, respectively; P = 0.013).

Conclusions: There is a possible association between FMS and anti-TS-HDS IgM. This association might be the missing link for the coexistence of SFN and FMS, but further study should be performed to assess this association and this auto-antibody characteristic.

Background: Bicalutamide monotherapy (BMT) is an option for androgen deprivation therapy (ADT) in patients with low- and intermediate-risk prostate cancer (LIR-PC). Painful gynecomastia (PG) is a common side effect of BMT. Few therapeutic options are available for preventing BMT-induced PG.

Objectives: To assess the efficacy and side effects of single fraction (SF) prophylactic breast irradiation (PBI) to prevent painful gynecomastia (PG) in patients LIR-PC treated with BMT.

Methods: We reviewed the results of bilateral PBI in a prospective cohort of LIR-PC patients who received 150 mg bicalutamide daily as a first-line treatment for at least 12 months. A single fraction of 8 Gy was administered to both breasts by a stationary field of 10 × 10 cm, using 10–15 MeV electron beam. PBI was commenced on the same day as BMT, but prior to the first dose of bicalutamide. A radiotherapy treatment plan was designed to cover breast tissue by the 90% isodose line. Subsequent monthly physical examinations were scheduled for all patients during the first year of BMT to evaluate any PG symptoms.

Results: Seventy-six patients received BMT and PBI, 80% (61/76) showed no signs of PG; 20% (15/76) experienced mild gynecomastia. The main adverse effect of PBI was grade 1 radiation dermatitis.

Conclusions: PBI using a SF of 8 Gy is an effective, safe, and low-cost strategy for the prevention of BMT-induced PG in LIR-PC patients.

Background: Serasis® (Serag-Wiessner KG, Naila, Germany) is a light-weight mid-urethral sling for treating stress urinary incontinence (SUI). Its insertion is considered less traumatic than other mid-urethral slings.

Objectives: To define postoperative outcomes following Serasis implantation. To compare the efficacy and complication rates of the implant to those of other common techniques.

Methods: Our retrospective study evaluated patients who underwent Serasis mid-urethral sling surgery for SUI. Data were collected from medical records prior to and at the time of surgery and by telephonic interview for postoperative pain and complications. Follow-up of patients was performed for up to one year postoperatively. Patients rated pain or discomfort according to the Visual Analogue Scale (VAS). The primary outcome was the development of early postoperative pain during the first month after surgery. Secondary outcomes were relief of SUI symptoms, groin pain or discomfort, and other postoperative complications up to 12 months after surgery.

Results: The study cohort included 50 consecutive patients aged 31 to 68 years. All patients underwent Serasis implantation procedures by a single surgeon and completed interviews. In total, 35 patients underwent concomitant anterior colporrhaphy. In the immediate postoperative period and at one month after the procedure, complaints were mild. No complaints were recorded during the 12-month follow-up period. Overall, 90% and 92% of the patients were free of SUI symptoms at one month and 12 months after surgery, respectively.

Conclusions: Serasis mid-urethral sling is safe, effective, and associated with mild postoperative pain and a low incidence of complications.

Stress urinary incontinence (SUI), defined as involuntary leakage of urine associated with increased intra-abdominal pressure during an effort such as sneezing or coughing, is a highly prevalent condition that affects women of all ages and impacts a women's quality of life (QoL). The prevalence of SUI reaches 14% in younger women and up to 35% in older women. Vaginal deliveries, gravidity, advanced age, menopause status, obesity, diabetes, and ethnicity are known risk factors for SUI [1].

Background: Statin-induced myalgia is defined as muscle pain without elevation of serum creatine phosphokinase levels and is a well-known complaint among statin users. Chronic pain syndromes affect a high percentage of the population. These pain syndromes may confound the reports of statin-induced myalgia.

Objectives: To compare the occurrence of chronic pain among patients on statin therapy who developed myalgia with those who did not.

Methods: This study included 112 statin-treated patients, who were followed at the lipid center at Sheba Medical Center. Fifty-six patients had a diagnosis of statin-associated muscle symptoms (SAMS) and 56 did not. Verified questionnaires were used to assess the diagnoses of fibromyalgia, pain intensity, functional impairment, anxiety, and depression in the study population.

Results: Patients with statin myalgia were more likely to fulfil the diagnostic criteria for fibromyalgia than patients without statin myalgia (11 [19.6%] vs. 0, respectively). Patients in the SAMS group exhibited higher levels of anxiety and depression compared with the control group. Female sex, higher scores on the Brief Pain Inventory pain intensity scale, and a Hamilton rating scale level indicative of an anxiety disorder were found to be significant predictors for fibromyalgia in patients presenting with statin myalgia.

Conclusions: A significant percentage of patients diagnosed with statin myalgia fulfilled the diagnostic criteria for fibromyalgia depression or anxiety disorder. Detection of these patients and treatment of their primary pain disorders or psychiatric illnesses has the potential to prevent unnecessary cessation of effective statin therapy.

Background: Pain control in trauma is an integral part of treatment in combat casualty care. More soldiers injured on the battlefield need analgesics for pain than life-saving interventions (LSIs). Early treatment of pain improves outcomes after injury, while inadequate treatment leads to higher rates of post-traumatic stress disorder (PTSD).

Objective: To describe the experience of the Israel Defense Forces (IDF) Medical Corps with prehospital use of analgesia.

Methods: All cases documented in the IDF-Trauma Registry between January 1997 and December 2019 were examined. Data collection included analgesia administered, mechanism of injury, wound distribution, and life-saving interventions performed.

Results: Of 16,117 patients, 1807 (11.2%) had at least one documented analgesia. Demographics included 91.2% male; median age 21 years. Leading mechanism of injury was penetrating (52.9%). Of injured body regions reported, 46.2% were lower extremity wounds. Most common types of analgesics were morphine (57.2%) and fentanyl (27%). Over the two decades of the study period, types of analgesics given by providers at point of injury (POI) had changed. Fentanyl was introduced in 2013, and by 2019 was given to 39% of patients. Another change was an increase of casualties receiving analgesia from 5–10% until 2010 to 34% by 2019. A total of 824 LSIs were performed on 556 patients (30.8%) receiving analgesia and no adverse events were found in any of the casualties.

Conclusions: Most casualties at POI did not receive any analgesics. The most common analgesics administered were opioids. Over time analgesic administration has gained acceptance and become more commonplace on the battlefield.

Background: Pain management is fundamental in the treatment of a trauma casualty. Adequate pain management is associated with decreased long-term morbidity and chronic pain. Nonetheless, pain is frequently not documented nor adequately treated in the prehospital setting, a phenomenon described as oligoanalgesia. Gender bias has been suggested as a risk factor for oligoanalgesia.

Objectives: To examine the association between casualty gender and pain management in the prehospital trauma setting.

Methods: We conducted a retrospective cohort study of the Israel Defense Forces Trauma Registry between 2015 and 2020. Univariable analysis followed by multivariable logistic regression was used to assess the association between casualty gender and pain management. For adult patients for whom gender was known, pain scores were documented.

Results: A total of 1044 casualties were included in the study; 894 (85.6%) were male. Females and males differed in several demographic and injury characteristics, including age in years (mean 36 vs. 27.6, P value < 0.001) and injury mechanism (16%% vs. 34.5% penetrating injury, P value < 0.001). Female casualties were less likely to be treated for pain (odds ratio [OR] 0.708, 95% confidence interval [95%CI] 0.5–1, P = 0.05). However, after adjustment for various factors, including pain severity, this association was insignificant (OR 0.748, 95%CI 0.46–1.23, P = 0.25).

Conclusions: In this prehospital study, gender bias in pain management was not apparent. As women’s role on the battlefield continues to increase, further studies regarding the role of

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.
