Children affected with Poland syndrome are born with missing or underdeveloped muscles (typically pectoralis major) on one side of the body. Breast abnormalities such as unilateral hypoplasia or agenesis of the breast and nipple may also occur. Other muscles on the affected side, including other muscles in the chest wall, shoulder, arm, and hand, may be missing or underdeveloped [1]. Ribs may be noticeable due to the loss of subcutaneous fat. Sparse or absent axillary and pectoral hairs are a common manifestation of this syndrome.

Background: Abdominal pathology in pregnant patients is a frequent challenge for emergency department physicians. Ultrasound is the imaging modality of choice but is inconclusive in approximately one-third of cases. Magnetic resonance imaging (MRI) is becoming increasingly available, even in acute settings. Multiple studies have defined the sensitivity and specificity of MRI in this population.

Objectives: To evaluate the use of MRI findings in pregnant patients presenting with acute abdominal complaints to the emergency department.

Methods: This retrospective cohort study was conducted at a single institution. Data were collected on pregnant patients who underwent an MRI for acute abdominal complaints between 2010 and 2019 at a university center. Patient demographics, diagnosis at admission, ultrasound and MRI findings, and discharge diagnosis were recorded and evaluated.

Results: In total, 203 pregnant patients underwent an MRI for acute abdominal complaints during the study period. MRI was found without pathology in 138 cases (68%). In 65 cases (32%), the MRI showed findings that could explain the patient's clinical presentation. Patients presenting with long-standing abdominal pain (> 24 hours), fever, leukocytosis, or elevated C-reactive protein values were at a significantly increased risk of having an acute pathology. In 46 patients (22.6%), MRI findings changed the primary diagnosis and management while in 45 patients (22.1%) MRI findings improved characterization of the suspected pathology.

Conclusions: MRI is helpful when clinical and sonographic findings are inconclusive, leading to changes in patient management in more than one-fifth of patients.

Background: Trabecular bone score (TBS) reflects vertebrae microarchitecture and assists in fracture risk assessment. The International Society of Clinical Densitometry postulates that the role of TBS in monitoring antiresorptive therapy is unclear. Whether changes in TBS correlate with bone resorption measured by bone turnover markers is not known.

Objectives: To determine whether longitudinal changes in TBS correlate with C-terminal telopeptide (CTX) of type I collagen.

Methods: Examinees with two bone mineral density (BMD) measurements were detected via the institutional database. Over 5.8% change in TBS was considered least significant and patients were grouped accordingly (increment, decrement, or unchanged). CTX, BMD, co-morbidities, incident fractures, and medication exposure were compared between the groups by Kruskal-Wallis. The correlation between TBS and BMD change and CTX in a continuous model was analyzed by Pearson's correlation coefficient.

Results: In total, 110 patients had detailed medical records. In 74.5%, TBS change was below least significant change. Two other TBS categories, fracture incidence or medication exposure, did not differ by CTX. In the continuous model, BMD and TBS change was positively correlated (r = 0.225, P = 0.018). A negative correlation was observed between BMD change and CTX. The decrease in BMD level was associated with higher CTX (r = -0.335, P = 0.004). No correlation was observed between CTX and TBS.

Conclusions: No correlation between TBS dynamics and bone resorption marker was found. Clinical interpretation and implication of longitudinal TBS changes should be further explored.

Background: Among chronic kidney disease (CKD) patients, baseline neutrophil gelatinase-associated lipocalin (NGAL) may reflect the severity of renal impairment. No data exists on serial changes in serum NGAL levels in CKD patients before and after percutaneous coronary intervention (PCI).

Objectives: To evaluate serial serum NGAL levels relation to contrast induced acute kidney injury (CI-AKI) following PCI.

Methods: The study included 58 patients with CKD who underwent elective PCI. Plasma NGAL measurements were performed before (pre-NGAL) and 24 hours following (post-NGAL) PCI. Patients were followed for CI-AKI and changes in NGAL levels. Receiver operator characteristic identified the optimal sensitivity and specificity for pre-NGAL levels compared with post-NGAL for patients with CI-AKI.

Results: Overall CI-AKI incidence was 33%. Both pre-NGAL (172 vs. 119 ng/ml, P < 0.001) and post-NGAL (181 vs. 121 ng/ml, P < 0.001) levels were significantly higher in patients with CI-AKI, but no significant changes were detected. Pre-NGAL levels were similar to post-NGAL levels in predicting CI-AKI (area under the curve 0.753 vs. 0.745). Optimal cutoff value for pre-NGAL was 129 ng/ml (sensitivity of 73% and specificity of 72%, P < 0.001). Post-NGAL levels > 141 ng/ml were independently associated with CI-AKI (hazard ratio [HR] 4.86, 95% confidence interval [95%CI] 1.34–17.64, P = 0.02) with a strong trend for post-NGAL levels > 129 ng/ml (HR 3.46, 95%CI 1.23–12.81, P = 0.06).

Conclusions: In high-risk patients, pre-NGAL levels may predict CI-AKI. Further studies on larger populations are needed to validate the use of NGAL measurements in CKD patients.

Background: Massive, non-compressible bleeding is a leading cause of preventable trauma mortality. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a minimally invasive procedure in which a balloon catheter is maneuvered into the aorta to temporarily occlude large vessels and enable stabilization of the exsanguinating patient.

Objectives: To present experiences in assimilating REBOA at a single level 1 trauma center in Israel, to evaluate the technical aspects of the procedure, and to describe patient characteristics and outcomes.

Methods: This retrospective cohort study comprised civilians admitted with hemorrhagic shock to our trauma department who were treated with REBOA between November 2017 and July 2021. Descriptive statistics of the patients, characteristics of the injuries and patient outcomes are presented.

Results: The study included 22 patients (median age 30.1 years, 21 male). The mean systolic blood pressure (SBP) before REBOA inflation was 59.6 ± 11.4 mmHg, and the mean SBP measured after the procedure was 115.2 ± 26.3 mmHg. In 20 patients (91%), the SBP was normalized (> 90 mmHg) shortly after inflation of the balloon, and they survived the treatment in the trauma department; 15 (75%) survived the first 30 days.

Conclusions: REBOA is an effective method for the initial resuscitation and hemorrhage control of patients with massive, non-compressible bleeding and is relatively easy to assimilate in a hospital. The achievement of immediate normalization of SBP enables medical personnel to correct physiological parameters and obtain accurate imaging before proceeding to the operating theater.

Background: During coronavirus disease 2019 (COVID-19) pandemic, less isolation of common winter viruses was reported in the southern hemisphere.

Objectives: To evaluate annual trends in respiratory disease-related admissions in a large Israeli hospital during and before the pandemic.

Methods: A retrospective analysis of medical records from November 2020 to January 2021 (winter season) was conducted and compared to the same period in two previous years. Data included number of admissions, epidemiological and clinical presentation, and isolation of respiratory pathogens.

Results: There were 1488 respiratory hospitalizations (58% males): 632 in 2018–2019, 701 in 2019–2020, and 155 in 2020–2021. Daily admissions decreased significantly from a median value of 6 (interquartile range [IQR] 4–9) and 7 per day (IQR 6–10) for 2018–2019 and 2019–2020, respectively, to only 1 per day (IQR 1–3) in 2020–2021 (P-value < 0.001). The incidence of all respiratory viruses decreased significantly during the COVID-19 pandemic, with no hospitalizations due to influenza and only one with respiratory syncytial virus. There was also a significant decline in respiratory viral and bacterial co-infections during the pandemic (P-value < 0.001).

Conclusions: There was a significant decline in pediatric respiratory admission rates during the COVID-19 pandemic. Possible etiologies include epidemiological factors such as mask wearing and social distancing, in addition to biological factors such as viral interference. A herd protection effect of adults and older children wearing masks may also have had an impact.

Background: Acute coronary syndrome (ACS) represents a spectrum of ischemic myocardial disease including unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI), and ST-elevation myocardial infarction (STEMI). Various prognostic scores were developed for patients presenting with NSTEMI-ACS. Among these scores, the GRACE risk score offers the best discriminative performance for prediction of in-hospital and 6-month mortality. However, the GRACE score is limited and cannot be used in several ethnic populations. Moreover, it is not predictive of clinical outcomes other than mortality.

Objective: To assess the prognostic value of traditional cardiovascular risk factors and laboratory biomarkers in predicting 6-month major adverse cardiac and cerebrovascular events (MACCE), including hospitalization, recurrent percutaneous coronary intervention (PCI), stroke, and cardiovascular mortality in patients with NSTEMI treated with PCI.

Methods: This retrospective study included consecutive patients admitted with an initial diagnosis of NSTEMI to the cardiac intensive care unit (CICU) at the Tzafon Medical Center, Israel, between April 2015 and August 2018 and treated by PCI within 48 hours of admission.

Results: A total of 223 consecutive patients with NSTEMI treated by PCI were included in the study. Logarithmebrain natriuretic peptide (LogₑBNP), prior MI, and Hb levels were found to be significant predictors of any first MACCE. Only logₑBNP was found to be an independent predictor of a first MACCE event by multivariate logistic regression analysis.

Conclusions: LogₑBNP is an independent predictor of worse prognosis in patients with NSTEMI. Routine evaluation of BNP levels should be considered in patients admitted with NSTEMI.

Background: Clinical investigations of long-term effects of coronavirus disease 2019 (COVID-19) are rarely translated to objective findings.

Objectives: To assess the functional capacity of individuals reported on deconditioning that hampered their return to their pre-COVID routine.

Methods: Assessment included the 6-minute walk test (6MWT) and the 30-second sit-to-stand test (30-STST). We compared the expected and observed scores using the Wilcoxon signed-rank test. Predictors of test scores were identified using linear regression models.

Results: We included 49 individuals, of whom 38 (77.6%) were recovering from mild COVID-19. Twenty-seven (55.1%) individuals had a 6MWT score lower than 80% of expected. The average 6MWT scores were 129.5 ± 121.2 meters and 12.2 ± 5.0 repeats lower than expected scores, respectively (P < 0.001 for both). The 6MWT score was 107.3 meters lower for individuals with severe COVID-19 (P = 0.013) and rose by 2.7 meters per each 1% increase in the diffusing capacity of carbon monoxide (P = 0.007). The 30-STST score was 3.0 repeats lower for individuals who reported moderate to severe myalgia (P = 0.038).

Conclusions: Individuals with long COVID who report on deconditioning exhibit significantly decreased physical capacity, even following mild acute illness. Risk factors include severe COVID-19 and impaired diffusing capacity or myalgia during recovery.

Background: Anal squamous cell carcinoma (ASqCC) is a rare malignancy, traditionally treated with combined chemoradiation, with a continuous infusion of 5-fluorouracil (5-FU) and mitomycin C (MMC). Replacing intravenous (IV) 5-FU with oral capecitabine (oral fluoropyrimidine) has been reported as a non-inferior treatment option. However, these data are scarce, with variable results.

Objectives: To examine the outcome of patients with ASqCC treated with either IV 5-FU or capecitabine concomitantly with radiation therapy. To compare treatment side effects, local recurrence, and general outcome.

Methods: We reviewed charts of patients who were diagnosed with stage I–III ASqCC. All participating patients received chemoradiation at the Assuta Medical Center between 2011 and 2019.

Results: In this study, 43 patients with ASqCC were eligible; 14 received 5-FU and 29 were treated with capecitabine. Basic characteristics were similar between the two groups, with longer follow-up for the 5-FU group. Six months following treatment, 100% (13/13 with adequate follow-up) of the 5-FU group had complete clinical response, compared to 84% in the capecitabine group (21/24), P = 0.143. The local recurrence incidence was higher in the 5-FU group at 23% (7, 10, 26 months following therapy, and none in the capecitabine group (P = 0.088). Although local and hematological toxicities were similar between groups, one patient receiving capecitabine died during chemoradiotherapy.

Conclusions: Oral capecitabine demonstrated non-inferior disease control in ASqCC treated with chemoradiotherapy. We recommend oral capecitabine over continuous IV 5-FU in locally and locally advanced ASqCC. Close monitoring of side effects is required to reduce major toxicity.

Takotsubo syndrome (TTS) often develops following stressors such as cardiac surgery. It may be fatal in rare cases. Our 70-year-old female patient presented with a rare case of tricuspid valve papillary fibroelastoma, which was complicated by fatal TTS after successful resection. The patient had a right atrial mass that was investigated with computed tomography and transesophageal echocardiography (TTE). She was scheduled for surgery. Pathology findings were consistent with papillary fibroelastoma of the tricuspid valve. Three weeks after successful surgery, the patient was admitted due to cardiogenic shock with echocardiographic findings of apical ballooning and left ventricular outflow tract obstruction consistent with TTS. The patient died one hour after her admission despite optimal medical therapy.

Background: Polyp detection rate (PDR) is a convenient quality measure indicator. Many factors influence PDR, including the patient's background, age, referral (ambulatory or hospitalized), and bowel cleansing.

Objectives: To evaluate whether years of professional experience have any effect on PDR.

Methods: A multivariate analysis of a retrospective cohort was performed, where both patient- and examiner-related variables, including the experience of doctors and nurses, were evaluated. PDR, as the dependent variable was calculated separately for all (APDR), proximal (PPDR), and small (SPDR) polyps.

Results: Between 1998 and 2019, 20,996 patients underwent colonoscopy at a single center. After controlling for covariates, the experience of both doctors and nurses was not found to be associated with APDR (odds ratio [OR] 0.99, 95% confidence interval [95%CI] 0.98–1.00, P = 0.15 and OR 1.03, 95%CI 1.02–1.04, P < 0.0001, respectively). However, after 2.4 years of colonoscopy experience for doctors, and 9.5 years of experience for nurses, a significant increase in APDR was observed. Furthermore, results revealed no association for PPDR and SPDR, as well.

Conclusions: Years of colonoscopy experience for both doctors and assisting nurses were not associated with APDR, PPDR, and SPDR. In doctors with 2.4 years of experience and nurses with 9.5 years of experience, a significant increase in APDR was observed.

Background: Population screening for the BRCA mutations in Ashkenazi Jewish women was recently implemented in Israel and is expected to lead to a 10-fold increase in the diagnosis of asymptomatic carriers. Performing the screening follow-up within multidisciplinary dedicated clinics for carriers is recommended for early detection and risk reduction.

Objectives: To determine the availability, capacity, and practices of dedicated screening clinic for BRCA carriers in Israel.

Methods: A telephone-based survey of all public hospitals in Israel was conducted October 2020 to August 2021 to determine whether they had a dedicated clinic. Dedicated clinics were defined as multidisciplinary screening clinics offering at least breast and gynecological screening and risk reducing services on site. The clinic director or nurse navigator answered a questionnaire about screening practices followed by a semi-structured interview.

Results: Of the ten dedicated BRCA clinics found in Israel, nine participated. Approximately 4500 BRCA carriers are currently being followed. No specialized clinics are available in the southern district or in the northernmost half of the northern district of Israel, leading to a disparity between periphery and center. Screening recommendations, although asserted as adhering to international guidelines, vary among clinics including age at initiating of clinical exam, use of adjunct imaging modalities, and follow-up during lactation and after risk reducing surgery.

Conclusions: There is a suboptimal distribution of dedicated clinics for BRCA carriers in Israel. Nationally centralized attempt to create guidelines that will unify screening practices is warranted, especially considering the expected increase in demand.

Background: Chronic suppurative otitis media is a long-standing middle ear infection with a perforated tympanic membrane. Tympanoplasty is the mainstay of treatment. Most surgeons prefer to operate on dry ears; however, this may be difficult to achieve.

Objectives: To investigate the effect of otorrhea and positive cultures on the outcome of tympanoplasty.

Methods: This retrospective analysis reviewed patients with chronic suppurative otitis media who underwent tympanoplasty 2008–2015. Patients were divided into three groups: active discharge and bacterial growth, active discharge without bacterial growth, and no ear discharge. Surgical outcomes were compared among the groups.

Results: Among 101 patients included, 43 ears (42.6%) had discharge preoperatively, 58 (57.4%) were dry. Overall closure rate was 81.2% (82/101). Preoperative active discharge closure rate was 88.3% (38/43) and without discharge 75.9% (44/58). There were 38 positive cultures preoperatively and five negative cultures. Cultures were not obtained in 58 cases. Success rates were 89.5%, 80%, and 75.9%, respectively. No significant difference was found between patients who had positive or negative cultures before the procedure (P > 0.48) or among the three groups (P = 0.25). The most common bacteria were Pseudomonas aeruginosa (n=17), followed by Staphylococcus species (n=10). None was significantly associated with operative failure (P = 0.557). The postoperative air threshold difference was not affected by culture results (P = 0.3).

Conclusions: Tympanoplasty success rates and postoperative air threshold differences were not affected by the presence of preoperative otorrhea or positive ear cultures. Surgery can be performed even when the ear is not dry.

At the end of 2019, the world faced a new virus–coronavirus disease 2019 (COVID-19)–which quickly became a pandemic. It has become clear that the COVID-19 virus can affect various body systems. Over time, we are finding more and more diverse manifestations of the course of the disease itself, its consequences, and complications. There have been several studies and reviews describing circulating antibodies in patients infected with COVID-19 (e.g., antinuclear antibodies [ANA], anti-cardiolipin, anti-B2 glycoprotein, perinuclear anti-neutrophil cytoplasmic antibodies [p-ANCA], cytoplasmic ANCA [c-ANCA]). The development of autoimmune disorders has been reported (e.g., Graves' disease, systemic lupus erythematosus (SLE), immune thrombocytopenia [ITP], diabetes mellitus [DM] type 1, psoriasis). There are descriptions of COVID-19 associated vasculitis include Kawasaki-like symptoms in children and immunoglobulin A (IgA) vasculitis in children and adults [1].
