Background: Obliterative vaginal procedures may offer lower perioperative morbidity and equal success rates as reconstructive procedures for frail and elderly women who no longer desire future coital function. The combination of vaginal hysterectomy with either reconstructive or obliterative vaginal procedures has not yet been investigated.

Objectives: To compare peri- and postoperative outcomes of vaginal hysterectomy with pelvic floor reconstruction (VHR) vs. vaginal hysterectomy with colpocleisis (VHC).

Methods: We conducted a retrospective study comparing medical and surgical data of patients undergoing either VHR or VHC between 2006 and 2015. Data were obtained from inpatient and outpatient medical records including peri- and postoperative course, as well as long-term (24 months) follow-up data.

Results: We identified 172 patients who underwent VHR and 44 who underwent VHC. Patients in the VHC group were significantly older (71.3 ± 4.5 vs. 68.6 ± 6.5 years, P = 0.01), and more likely to have medical co-morbidities (P = 0.001 and P = 0.029, respectively). Patients in the VHC group experienced shorter operative time (2.3 ± 0.58 vs. 2.7 ± 1.02 hours, P = 0.007), lower perioperative blood loss (P < 0.0001), shorter hospital stay (P < 0.0001), and lower rates of postoperative urinary retention. Long-term pelvic organ prolapse (POP) recurrence rates were significantly higher among the VHR group. Postoperative resolution of both stress urinary incontinence and overactive bladder were common in both groups.

Conclusions: VHC is associated with lower perioperative blood loss, shorter operative time, shorter hospital stay, shorter time with an indwelling catheter, and lower long-term objective POP recurrence rates.

Higher potency bisphosphonates, typically intravenous formulations, are given at lower doses for postmenopausal women. The treatment has improved compliance compared to daily oral therapy. Since bisphosphonates are exclusively excreted via the kidneys, intravenous formulation has been associated with deterioration of renal function, specifically in the setting of preexisting renal disease or concomitant use of nephrotoxic agents [1].

Background: At the beginning of 2020, the coronavirus disease 2019 (COVID-19) pandemic presented a new burden on healthcare systems.

Objectives: To evaluate the impact of the COVID-19 pandemic on the outcome of non-COVID patients in Israel.

Methods: We conducted a retrospective observational cohort study at a tertiary medical center in Israel. From December 2018 until June 2022, 6796 patients were hospitalized in the internal medicine wards. Patients were grouped based on their admission date: admitted during COVID waves (waves group), admitted between waves (interim group), and admitted during the same months in the previous year (former-year group).

Results: Mortality during hospitalization and 30-day mortality were higher in the waves group compared to the interim and former-year groups (41.4% vs. 30.5% and 24%, 19.4% vs. 17.9% and 12.9%, P < 0.001). In addition, 1-year mortality was higher in the interim group than in the waves and former-year group (39.1 % vs. 32.5% and 33.4%, P = 0.002). There were significant differences in the readmissions, both at 1 year and total number. The waves group had higher rates of mechanical ventilation and noradrenaline administration during hospitalization. Moreover, the waves group exhibited higher troponin levels, lower hemoglobin levels, and more abnormalities in liver and kidney function.

Conclusions: Hospitalized non-COVID patients experienced worse outcomes during the peaks of the pandemic compared to the nadirs and the preceding year, perhaps due to the limited availability of resources. These results underscore the importance of preparing for large-scale threats and implementing effective resource allocation policies.

Klippel-Trenaunay syndrome (KTS) is a rare congenital complex vascular multisystem disorder characterized by bony and soft-tissue hypertrophy. It is famous for its hallmarks like port-wine stains and varicose veins. The syndrome is sporadic, although rare familial cases have been reported [1]. The most common ophthalmological alterations encountered in KTS are conjunctival telangiectasia, anterior chamber malformation, raised episcleral venous pressure with associated glaucoma, and choroidal hemangiomas [2].

The purpose of this report is to raise awareness of KTS and its diverse scale of expressions as well as complications. This study was conducted in accordance with the ethical standards set by the Declaration of Helsinki. The patient gave signed informed consent.

Psoriatic arthritis can present with significant hand and wrist deformity and dysfunction [1]. The development of newer biological therapies has resulted in higher rates of remission [2]. However, surgical intervention is still indicated in pain, disability, and severe deformation cases. The management of patients with rheumatic diseases has a controversial history, characterized by rheumatologists and hand surgeons debating the efficacy of surgical interventions. Some surgeons attribute the controversial results to “too little and too late” referral of patients from rheumatologists [3]. While the availability of new and more effective medication has changed the indications and postponed surgical intervention, it is important to remember that surgery is often more effective when used preventively in the early stages than when forced to salvage. In the following case, we present a patient with psoriatic arthritis who presented with advanced-stage debilitating hand deformity and was treated surgically.

Carpal tunnel syndrome (CTS) is a collection of symptoms and signs caused by compression of the median nerve as it travels through the carpal tunnel. Symptoms include paresthesia and/or numbness in the median nerve distribution, aching in the thenar eminence, and weakness at later stages. CTS is the most common entrapment neuropathy with a prevalence of 1–5%, and even higher among females, manual workers, and the elderly. Therefore, many patients with signs and symptoms of CTS refer to their primary care physician who should recognize, diagnose, and provide initial treatment.

BackgroundSeveral approaches are used to access the hip joint; most common are the direct lateral and posterior. Little consensus exists on which to use when treating hip fractures.

Objectives: To compare short-term complications, postoperative ambulation, and patient-reported outcome measures (PROMS) of direct lateral vs. posterior approaches in hemiarthroplasty for acute hip fractures.

Methods: We conducted a retrospective clinical trial with 260 patients who underwent bipolar hemiarthroplasty in the direct lateral or posterior approach (166 and 94, respectively) between January 2017 and December 2018. The clinical data included short-term complications: prosthetic dislocation, periprosthetic fractures, and infection. Postoperative ambulation was collected 6 weeks postoperatively; PROMS were collected for 173 patients at 2 years follow-up.

Results: There were six dislocations overall, average time to dislocation was 22 days postoperative (range 4–34). Five dislocations were after the posterior approach (5.3%) and one after direct lateral (0.6%) (P = 0.01). At 6 weeks follow-up, inability to walk was found in 16.9% of the direct lateral group and 6.4% of the posterior approach group (P = 0.02). In the posterior approach group, 76% could walk more than 20 meters; only half of the direct lateral group could (P = 0.0002). At 2 years follow-up, PROMS did not show a statistically significant difference between the groups.

Conclusions: Posterior approach for hemiarthroplasty following femoral neck fractures allows superior ambulation to the direct lateral approach only for the short-term. However, no long-term clinical advantage was found. This short-term benefit does not justify the increased dislocation rate in the posterior approach.

The prevalence of pelvic organ prolapse (POP) varies greatly and is reported to be between 3% and 50% differing greatly when based on POP symptoms or vaginal examination [1]. Age is a well-established risk factor in the reported prevalence of POP [2]. With advancing age, the prevalence escalates dramatically, from 6% at age of 30 years to over 50% at the age of 80 years [3]. The increase in life expectancy observed in recent years will most probably be accompanied by a respective increase in the absolute numbers of women presenting with POP [4]. POP is a major health burden and is expected to continue being so in the upcoming future; hence, the importance of a safe and efficient treatment.

Background: Vaginal hysterectomy (VH) and colpocleisis are both used for the treatment of advanced pelvic organ prolapse (POP).

Objective: To compare short- and long-term outcomes of vaginal hysterectomy vs. colpocleisis for advanced POP.

Methods: Hospital and outpatient charts of patients who underwent VH or colpocleisis at our institution between January 2006 and December 2015 were reviewed. Clinical data were obtained and analyzed.

Results: In this study, 188 patients underwent VH and 32 patients underwent colpocleisis. The colpocleisis group was significantly older than the VH group (79.5 ± 4.5 vs. 69 ± 6.1 years respectively, P < 0.0001) and presented with significantly higher co-morbidity rates and a higher degree of POP. Perioperative blood loss was significantly lower (250 ± 7.6 ml vs. 300 ± 115 ml, P < 0.0001) and postoperative hospitalization was significantly shorter (2 ± 2.7 vs. 3 ± 2.2 days, P = 0.015) among the colpocleisis group. None of the patients from the colpocleisis group required an indwelling urethral catheter after discharge, compared to 27.5% of the patients from the VH group (P = 0.001). Total postoperative complication rate was significantly lower among the colpocleisis group (25% vs. 31% P < 0.0001). Objective recurrence of POP was significantly more common among the VH group (7% vs. 0% and 21% vs. 0% for the anterior and posterior compartments, respectively, P = 0.04).

Conclusions: Colpocleisis is associated with faster recovery, lower perioperative morbidity, and higher success rates than VH and should be considered for frail and elderly patients.

Background: Rheumatoid arthritis (RA) is a chronic inflammatory and destructive joint disease with the presence of autoantibodies, rheumatoid factor (RF), and anti-citrullinated protein antibodies (ACPA). The presence of RF or ACPA predicts RA severity. Data on the influence of ACPA titer on RA course are limited.

Objectives: To determine the correlation between ACPA titers at the time of RA diagnosis to RA features and severity during 3 years of follow-up.

Methods: We performed a retrospective study of RA patients treated at our institution during the years 2006–2015 with known ACPA titers at RA diagnosis who completed at least 3 years of follow-up. Patients (N=133) were divided according to ACPA titer: seronegative (< 15 U/ml, n=55), weakly positive (15–49 U/ml, n=18), moderately positive (50–300 U/ml, n=29), and strongly positive (> 300 U/ml, n=31). Patient data, including disease activity score (DAS28), bone erosion on hand and/or foot X-rays, treatments with corticosteroids and disease-modifying-anti-rheumatic drugs (DMARDs), and hospitalizations, were recorded. Chi-square and Mann-Whitney method were used for statistical analysis. P < 0.05 was considered as statistically significant.

Results: Male gender, smoking, and RF positivity correlated with ACPA positivity and higher ACPA titers. There was no correlation between ACPA titer and the variables defined as representing RA severity: higher DAS28, bone erosions, hospitalizations, need for corticosteroids, and conventional and biological DMARDs.

Conclusions: Titer of ACPA was not identified as a predictive factor for RA severity

Background: Many procedures requiring sedation in the pediatric emergency department are performed by consultants from outside the department. This team usually includes orthopedic surgeons and general surgeons. As sedation is now a standard of care in such cases, we evaluated consultants' views on sedation.

Objectives: To evaluate consultants' views on sedation.

Methods: A questionnaire with both open-ended questions and Likert-type scores was distributed to all orthopedic surgeons and general surgeons performing procedures during the study period. The questionnaire was presented at three medical centers.

Results: The questionnaire was completed by 31 orthopedic surgeons and 16 general surgeons. Although the vast majority (93–100%) considered sedation important, a high percentage (64–75%) would still perform such procedures without sedation if not readily available.

Conclusions: Sedation is very important for patients and although consultants understand its importance, the emergency department staff must be vigilant in both being available and not allowing procedures to "escape" the use of sedation.

Background: Prophylactic cranial irradiation (PCI) exclusion in favor of brain magnetic resonance imaging (MRI) staging and surveillance in the management of small cell lung cancer (SCLC) is controversial yet accepted by some centers. The use of MRI suggests performing stereotactic radiosurgery (SRS) treatment for limited brain metastases. Data regarding SRS efficacy in this setting is limited.

Objectives: To assess intracranial objective response rate (iORR), progression-free survival (iPFS), intracranial failure patterns, overall survival (OS) and time-to-whole-brain radiation therapy (WBRT)/death, whichever occurred first (TTWD) with SRS in SCLC.

Methods: The study comprised 10 consecutive SCLC patients with brain metastases treated with SRS and followed-up at Davidoff Cancer center between Aug 2012 and March 2019. Brain MRI images were reviewed by a neuro-radiology specialist.

Results: iORR was 57% as assessed by response assessment in neuro-oncology brain metastases. Intracranial progression developed in 8 patients. Median iPFS was 4.0 months (95% confidence interval [95%CI] 1.7–7.2). In-site, off-site and combined pattern of intracranial failure was seen in 0, 5, and 3 patients, respectively; median number of new brain lesions following SRS was 4 (range, 1–12). SRS was performed 10 additional times in 6 patients (median number of lesions irradiated per round was 1, range 1–5). WBRT was administered in 3 patients. Median TTWD was 20.9 months (95% CI, 1.9–26.8). Median OS since SRS administration was 23.2 months (95% CI, 4.2–not reached).

Conclusions: MRI surveillance with multiple rounds of SRS may serve a reasonable alternative to PCI or therapeutic WBRT in SCLC.

Background: Benign rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes (BCECTS) is a common childhood epileptic syndrome. The syndrome resolves in adolescence, but 1–7% of patients have an atypical presentation, some of which require aggressive medical treatment. Early treatment may prevent complications and neurocognitive deterioration. Variants include Landau-Kleffner syndrome (LKS) and electrical status epilepticus during sleep (ESES).

Objectives: To determine data driven identification of risk factors and characterization of new subtypes of BCECTS based on anontology. To use data mining analysis and correlation between the identified groups and known clinical variants.

Methods: We conducted a retrospective cohort study comprised of 104 patients with a diagnosis of BCECTS and a minimum of 2 years of follow-up, between the years 2005 and 2017. The medical records were obtained from the epilepsy service unit of the pediatric neurology department at Dana–Dwek Hospital, Tel Aviv Sourasky Medical Center. We developed a BCECTS ontology and performed data preprocessing and analysis using the R Project for Statistical Computing (https://www.r-project.org/) and machine learning tools to identify risk factors and characterize subgroups.

Results: The ontology created a uniform and understandable infrastructure for research. With the ontology, a more precise characterization of clinical symptoms and EEG activity of BCECTS was possible. Risk factors for the development of severe atypical presentations were identified: electroencephalography (EEG) with spike wave (P < 0.05), EEG without evidence of left lateralization (P < 0.05), and EEG localization (centrotemporal, frontal, or frontotemporal) (P < 0.01).

Conclusions: Future use of the ontology infrastructure for expanding characterization for multicenter studies as well as future studies of the disease are needed. Identifying subgroups and adapting them to known clinical variants will enable identification of risk factors, improve prediction of disease progression, and facilitate adaptation of more accurate therapy. Early identification and frequent follow-up may have a significant impact on the prognosis of the atypical variants.

Background: The main acquired resistance mechanism to first- and second-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in EGFR mutant non-small cell lung cancer (NSCLC) is the propagation of T790M clones, which can be detected in circulating tumor DNA (ctDNA).

Objectives: To analyze osimertinib outcomes according to T790M testing method.

Methods: The study comprised 33 consecutive patients with advanced EGFR mutant NSCLC who were diagnosed with a T790M mutation after progression on first- or second-generation EGFR TKIs and treated with osimertinib. The patients were divided into groups A (diagnosed by tumor testing) and B (by ctDNA testing). Osimertinib outcomes were compared between the groups.

Results: Objective response rate with osimertinib comprised 54% and 62% in groups A and B, respectively (P = 0.58). Median progression-free survival (PFS) with osimertinib was 8.9 months (95% confidence interval [95%CI] 1.8–17.5) and 9.1 months (95%Cl 5.3–12.6) in groups A and B, respectively (log-rank test 0.12, P = 0.73). Median overall survival (OS) was 13.8 months (95%CI 4.9–25.5) and 13.8 months (95%Cl 7.7–27.7) in groups A and B, respectively (log-rank test 0.09, P = 0.75). T790M testing technique did not affect PFS (hazard ratio [HR] 1.16, 95%CI 0.50–2.69, P = 0.73) or OS (HR = 1.16, 95%CI 0.45–3.01, P = 0.76). The proportion of patients diagnosed by ctDNA grew from 56% in 2015 to 67% in 2016–2017.

Conclusions: Our study provides a ctDNA validation for the purpose of T790M testing in EGFR mutant NSCLC.
