Rheumatoid arthritis (RA) is an autoimmune chronic inflammatory disease characterized by synovitis leading to polyarthritis. It affects 1% of the population [1]. Genetic and environmental factors are linked to the development of RA and include the presence of HLA-DR4 and shared epitope, and smoking is the primary representative of the negative environmental factor [1].

However, RA mainly affects middle age. Late-onset RA that initiates after 60 years is sometimes named elderly onset rheumatoid arthritis (EORA) [2]. This disease's prevalence varied from 2.03% to 2.34% in a large study in the United States. EORA affects more women than men [1]. However, to the best of our knowledge, no patient description of RA initiated at 97 years of age has been described.

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.

Patients with severe ischemic and hemorrhagic stroke may require invasive mechanical ventilation due to loss of consciousness and increased risk for aspiration pneumonia secondary to new onset dysphagia. Ventilation may also confer airway protection until the patient stabilizes [1]. Mechanically intubated stroke patients who are admitted to the intensive care unit (ICU) have a poor prognosis and a 40–80 % mortality rate [2]. Proceeding to tracheostomy is mandatory in stroke patients to ease the procedure of respiratory weaning and extubation [1]. In the stroke ICU, between 15% and 35% of the mechanically intubated patients cannot proceed to tracheostomy due to weaning and extubation failure [3].

Common variable immunodeficiency (CVID) is a heterogeneous primary immune deficiency disorder characterized mainly by defective B lymphocyte differentiation, leading to hypogammaglobinemia and defective antibody production. It is often combined with cellular immune defects. A minority of patients present during childhood and adolescence. Infections are most often sinopulmonary but can affect any system. The noninfectious complications include progressive lung disease, autoimmunity, gastrointestinal inflammatory disease, liver disease, granulomatous disease, lymphoid hyperplasia and infiltrative disease, and the development of lymphoma and other cancers. In addition to recurrent infections and bronchiectasis, patients may develop chronic interstitial lung disease, granulomatous lung disease, lymphoma, and pulmonary hypertension.

Uveal melanoma (UM) affects approximately six individuals per million per year in the United States, with similar rates in Mediterranean countries. Although it appears to have a low prevalence, it is the most common primary intraocular malignancy in adults. Clinically, it presents in most patients as a painless loss or distortion of vision, although it may also be accidentally discovered at routine ophthalmic examination. Associated risk factors include fair skin tone, light eye color, presence of a choroidal nevus, oculodermal melanocytosis (nevus of ota), dysplastic nevus syndrome, and germline BRCA-associated protein 1 mutations (BAP1 mutations) [1].

Recent studies using propensity score matching have clearly indicated that contrast nephropathy following computed tomography occurs in hospitalized patients with advanced chronic kidney disease (eGFR < 30 ml/min/1.73 m²) and that this iatrogenic complication is likely underestimated because of concomitant renal functional recovery, unrelated to the imaging procedure. These findings should be considered regarding contrast-enhanced studies in such patients.

Background: Influenza and coronavirus disease 2019 (COVID-19) are respiratory diseases with similar modes of transmission. In December 2021, influenza re-emerged after it had been undetected since March 2020 and the Omicron variant replaced the Delta variant. Data directly comparing the two diseases are scarce.

Objectives: To compare the outcomes of patients with both the Omicron variant and influenza during 2021–2022.

Methods: We performed a retrospective study conducted in Beilinson hospital, Israel, from December 2021 to January 2022. We included all hospitalized patients with either laboratory-confirmed COVID-19 or influenza. The primary outcome was 30-day mortality.

Results: We identified 167 patients diagnosed with Omicron and 221 diagnosed with Influenza A. The median age was 71 years for Omicron and 65 years for influenza. Patients with Omicron had a significantly higher Charlson Comorbidity Index score (4 vs. 3, P < 0.001). Patients with Omicron developed more respiratory failure that needed mechanical ventilation (7% vs. 2%, P = 0.05) and vasopressors (14% vs. 2%, P < 0.001) than patients with influenza. In a multivariate model, 30-day mortality was lower in patients diagnosed with influenza than in patients diagnosed with Omicron (19/221 [9%] vs. 44/167 [26%], hazard ratio 0.45, 95% confidence interval 0.25–0.81).

Conclusions: Patients diagnosed with Omicron had higher mortality than patients diagnosed with seasonal influenza. This finding could be due to differences in co-morbidities, the virus pathogenicity, and host responses to infection.

Background: Data are scarce on the immunogenicity of coronavirus disease 2019 vaccines in patients with autoimmune rheumatic diseases (ARD).

Objectives: To measure the immunoglobulin G (IgG) response after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunization and to evaluate clinical characteristics associated with seropositivity.

Methods: Samples were collected after the second and third doses of the three different types of vaccines in ARD patients. Seroconversion rates and IgG antibody S1/S2 titers were measured.

Results: The type of ARD diagnosis and previous treatment had no significant impact on the serum IgG antibody levels measured after the second (P = 0.489 and P = 0.330, respectively) and boost dose (P = 0.441 and P = 0.446, respectively). What made a significant difference regarding serum IgG antibody levels after the second dose was the type of SARS-CoV-2 vaccine. The difference was highly statistically significant for all vaccine types (P = 0.001 with the highest odds ratio for the mRNA vaccine). After the boost with the mRNA vaccine, all patients achieved a high level of serum IgG antibody levels (t = 10.31, P = 0.001). No ARD patients experienced serious post-vaccinal reactions. Eight patients developed COVID-19 before the boost dose.

Conclusions: In ARDs patients, the highest level of serum IgG antibody against S1/S2 proteins was achieved with the mRNA vaccine, irrespective of the therapy applied or the type of the disease. We recommend a booster dose with mRNA vaccine in all ARDs for the highest SARS-CoV-2 protection without serious post-vaccinal reactions observed.

Background: At the beginning of the coronavirus disease 2019 (COVID-19) pandemic, many patients presented with acute hypoxemic respiratory failure, requiring ventilatory support. One treatment method was the addition of a reservoir mask to a high flow nasal cannula (HFNC) (dual oxygenation).

Objectives: To evaluate the clinical outcomes of combining reservoir mask on top of a high-flow nasal cannula.

Methods: A retrospective cohort of adult patients who were admitted due to COVID-19 during the first year of the pandemic to Rambam Health Care Campus. The primary endpoint was 30-day mortality. Secondary endpoints were incidence of invasive positive pressure ventilation initiation and admission to the intensive care unit (ICU). Patients who received positive pressure ventilation for reasons other than hypoxemic respiratory failure or who were transferred to another facility while still on HFNC were excluded.

Results: The final analysis included 333 patients; 166 were treated with dual oxygenation and 167 with HFNC only (controls). No significant differences in baseline characteristics were noted between the groups. The dual oxygenation group was slightly older (69.2 ± 14.8 years vs. 65.6 ± 15.5 years, P = 0.034). The 30-day mortality (24.1% vs. 36.5%, P = 0.013), rates of invasive positive pressure ventilation (47% vs. 59.3%, P = 0.024), and ICU admissions (41.6% vs. 52.7%, P = 0.042) were all significantly lower in the dual oxygenation group.

Conclusions: The addition of reservoir masks to HFNC may improve the oxygenation and overall prognosis in patients with severe hypoxemia due to COVID-19.

Background: Age-related changes in multiparametric magnetic resonance imaging (mpMRI) of the prostate have been reported in the general population but not in screening cohorts.

Objectives: To evaluate age-related changes on prostatic mpMRI in a screening cohort of BRCA1/2 mutation carriers.

Methods: Asymptomatic BRCA1/2 mutation carriers underwent mpMRI as part of a screening program. All included patients were followed for 3 years with no evidence of prostate cancer. mpMRIs were retrospectively evaluated by two abdominal radiologists for peripheral zone (PZ) patterns on T2 (homogenous hyperintensity, wedge-shaped hypointensities, patchy hypointensities, or diffuse hypointensity), and transition zone (TZ) pattern on T2 (homogenous, heterogeneous, nodular). Apparent diffusion coefficient (ADC) values of PZ and TZ were measured. Statistical analysis was performed using a predefined age cutoff of 50 years old.

Results: Overall, 92 patients were included: 38 in the younger age group (40–49 years) and 54 in the older age group (50–69 years). PZ homogenous hyperintensity and wedge-shaped hypointensities were more common in the older patients, whereas diffuse hypointensity was more common in younger patients (P < 0.001 for both readers) with substantial inter-reader agreement between the readers (kappa=0.643). ADC values were lower in young patients in the PZ (P < 0.001) and TZ (P = 0.003).

Conclusions: Age-related differences in mpMRI were validated in BRCA mutation carriers. As some features overlap with prostatic carcinoma, awareness is crucial, specifically to diffuse T2 hypointensities of the PZ and lower ADC values in the PZ and TZ, which are more common in younger patients.

Background: During combined phacovitrectomy, it is common practice to suture the main corneal incision to prevent intraoperative and postoperative wound leak. However, it may be possible to avoid suturing using a self-sealing corneal incision technique as in standard cataract surgery.

Objectives: To evaluate the clinical outcome, safety, and complications of combined phacovitrectomy without preventive suturing.

Methods: This retrospective case series study included consecutive patients who underwent combined phacovitrectomy between January 2018 and June 2019 for mixed indications. Surgeries were performed at a tertiary university hospital. All surgeries were performed by the same two retinal surgeons. Cataract surgery was performed first, followed by insertion of trocars and vitrectomy. Corneal sutures were not planned but were used at the discretion of the surgeon.

Results: The cohort included 106 eyes of 102 patients. Suturing of the main corneal incision was deemed necessary in five cases (5%) because of a main incision leak or anterior chamber shallowing during trocar insertion. No other complications related to the absence of prophylactic corneal sutures were encountered during surgery or follow-up.

Conclusions: Preventive corneal suturing may not be necessary in combined phacovitrectomy surgery and can be used in the few cases in which it is indicated during surgery.

Background: Long-term outcome data for bariatric surgery in patients with severe obesity (SO) (body mass index [BMI] ³ 50 kg/m²) are scarce.

Objectives: To compare perioperative morbidity and long-term outcomes between patients with SO and non-SO (NSO).

Methods: Patients with SO who underwent primary bariatric surgery with a follow-up ³ 5 years were age- and gender-matched with NSO patients in a retrospective, case-control study. Data included demographics, BMI, co-morbidities, early outcomes, current and nadir weight, co-morbidity status, and general satisfaction.

Results: Of 178 patients, 49.4% were male, mean age 44.5 ± 14 years. Mean preoperative BMI was 54.7 ± 3.6 and 41.8 ± 3.8 kg/m² in SO and NSO, respectively (P = 0.02). Groups were similar in preoperative characteristics. Depression/anxiety was more prevalent in NSO (12.4% vs. 3.4%, P = 0.03). Obstructive sleep apnea was higher in SO (21.3% vs. 10.1%, P = 0.04). Sleeve gastrectomy was performed most often (80.9%), with a tendency toward bypass in SO (P = 0.05). Early complication rates were: 13.5% in SO and 12.4% in NSO (P = 0.82). Mean follow-up was 80.4 ± 13.3 months. BMI reduction was higher in SO (31.8 ± 5.9 vs. 26.8 ± 4.2 kg/m², P < 0.001) and time to nadir weight was longer (22.1 ± 21.3 vs. 13.0 ± 12.0 months, P = 0.001). Co-morbidity improvement and satisfaction were similar.

Conclusions: Patients with SO benefited from bariatric surgery with reduced BMI and fewer co-morbidities. No added risk of operative complications was found compared to patients with NSO.

Background: There is an unmet need for real-world data regarding laboratory results, co-morbidities, and medication use prior to the first symptoms of amyotrophic lateral sclerosis (ALS). Researchers must identify specific subpopulations at risk for developing ALS and understand pathogenic mechanisms preceding the clinical presentation of ALS as well as possible subclinical disease manifestations.

Objectives: To valuate the role of laboratory results, co-morbidities, and medication use prior to the first symptoms of patients with ALS in Israel so that specific subpopulations at risk for developing ALS can be identified and for possible subclinical disease manifestations. To understand pathogenic mechanisms preceding the clinical presentation of ALS.

Methods: At the ALS clinic at Tel Aviv Sourasky Medical Center, 259 ALS patients insured by Maccabi Healthcare Services and seen between January 1998 and December 2017 were included. Comparisons of demographics, co-morbidities, medications taken, history of trauma, and laboratory tests prior to disease onset were performed between patients and 1295 matched controls.

Results: Prior to disease presentation, ALS patients had a higher frequency of hypertension and cardiovascular disease; presented more frequently with trauma and viral infections; more frequently used analgesics, non-steroidal anti-inflammatory drugs, narcotics, antibiotics, and antiviral medications; and had higher creatine kinase levels.

Conclusions: ALS patients showed higher frequency of cardiovascular disease prior to diagnosis, as well as higher frequency of trauma, infections, and pain medication usage.

Background: Congestive heart failure (CHF) with reduced ejection fraction (HFrEF) or with preserved ejection fraction (HFpEF) is a common diagnosis in patients hospitalized in the department of internal medicine. Recently, the therapeutic regimens were updated, as the sodium-glucose cotransporter-2 (SGLT2) inhibitors became an integral part of the therapeutic regimen for either HFrEF or HFpEF.

Objectives: To define the demographic and clinical characteristics of CHF patients hospitalized in the department of medicine.

Methods: We conducted a retrospective cohort study that included all patients hospitalized in the departments of medicine at the Rabin Medical Center, Israel, between 2016 and 2019. Demographic and clinical background, in-hospital procedures, discharge regimens, and outcome parameters were evaluated according to HFrEF/HFpEF.

Results: The cohort included 4458 patients. The majority (97%) presented with a preexisting diagnosis, whereas HF was an active condition in only half of them. The rates of HFrEF/HFpEF were equal. In most cases, the trigger of the exacerbation could not be determined; however, infection was the most common cause. There were basic differences in the demography, clinical aspects, and therapeutic regimens at discharge between HFrEF and HFpEF. Both conditions were associated with high in hospital mortality (8%) and re-admissions rates (30 days [20%], 90 days [35%]) without any difference between them.

Conclusions: HFrEF/HFpEF patients differed by demographics and co-morbidities. They were equally represented among patients admitted to medical wards and had similar prognosis. For both diagnoses, hospitalization should be considered for updating therapeutic regimens, especially with SGLT2 inhibitors.
