Background: Acute musculoskeletal pain is one of the most commonly reported symptoms among patients visiting the emergency department (ED). Treatment with over-the-counter pain medications, given by nurses, results in improved pain management and reduces the waiting time to drug administration without significant side effects. Opioid analgesics are extensively used for acute pain in the ED. Compared to morphine, oxycodone has a much more specific pharmacological activity, higher analgesic potential, and more tolerable side effects.

Objectives: To assess the degree of pain reduction using different protocols, including dypirone and oxycodone given by nurses, in treating acute musculoskeletal pain in the emergency department (primary outcome) and to evaluate the need for rescue medications (secondary outcome).

Methods: This observational prospective clinical trial compared two groups of 50 patients, each one visiting the ED due to musculoskeletal pain. One group was treated with dipyrone syrup and the other was treated with oxycodone syrup. The primary outcome was pain reduction measured by the Numeric Rating Scale (NRS). The secondary outcome was the difference in need for rescue medications.

Results: The reduction in the NRS was greater in the patients treated with oxycodone. This finding was statistically and clinically significant (P < 0.001). The need for rescue medications was also significantly reduced in this group of patients (P = 0.007).

Conclusions: This study showed that the administration of over-the-counter oxycodone syrup by nurses decreases the post-treatment pain reported by patients, reduces the need for rescue medications, and increases the satisfaction of the medical staff.

Background: Extended-spectrum beta-lactamase (ESBL) production is the most common antimicrobial resistance mechanism in the neonatal intensive care unit (NICU), with colonization and blood stream infections being a major threat to this population. Since 2013, all NICU admissions at our facility were screened twice weekly for ESBL colonization.

Objectives: To determine independent risk factors for colonization of infants with ESBL-producing bacteria in the NICU.

Methods: A retrospective case study of ESBL-colonized infants vs. controls (matched by date of birth and gestational age) was conducted in the NICU of Soroka University Medical Center, Israel, between 2013 and 2014. Epidemiological, laboratory, and clinical data were extracted from medical files. Univariable and multivariable analyses were used to assess associations between ESBL colonization and possible clinical risk factors.

Results: Of 639 admissions during the study period, 87 were found to be ESBL-colonized (case infants) and were matched to 87 controls. Five case infants became infected (5.7%) with ESBL strains. Klebsiella pneumoniae was the most common isolated bacteria. The mean time from admission to colonization was 15 days. Univariable analysis showed an association of male gender and highest Apgar score at 1 and 5 minutes with ESBL colonization (P < 0.05). Multivariable analysis yielded only a possible association of higher Apgar score at 1 and 5 minutes (hazard ratio [HR] 1.515, 95% confidence interval [95%CI] 0.993-2.314; HR 1.603, 95%CI 0.958–2.682, respectively) with ESBL colonization.

Conclusions: Future studies should focus on maternal colonization and possible strategies for preventing vertical transmission of ESBL strains to high-risk neonates.

The discovery of Jewish babies who were born in Nazi concentration camps and survived seems miraculous, but this phenomenon did occur toward the end of World War II. The lives of a small group of mothers and surviving children are of both historical and medical interests. Their survival shows additional support for the hypothesis that maternal nutrition can induce metabolic syndrome and bone demineralization in their offspring. Information obtained through direct contact with some of the surviving children is the basis for this article.

Background: Circulating endothelial progenitor cells have an important role in the process of vascular repair. Impaired recruitment and function of endothelial progenitor cells is related to the pathophysiology of congestive heart failure. Endothelial progenitor cells have been shown to express the mineralocorticoid receptor. 

Objectives: To investigate the effect of mineralocorticoid receptor antagonists on endothelial progenitor cells in patients with heart failure. 

Methods: Twenty-four patients with compensated heart failure, who were not under mineralocorticoid receptor antagonist therapy, were recruited. Either eplerenone (n=8) or spironolactone (n=16) therapy was initiated. Circulating endothelial progenitor cell level, identified as the proportion of mononuclear cells expressing vascular endothelial growth factor receptor 2 (VEGFR-2), CD133, and CD34, was evaluated by flow cytometry at baseline and after 8 weeks. Following 7 days of culture, colonies were counted by microscopy and MTT assay was performed on randomly selected patients (n=12) to estimate viability.

Results: Both median CD34+/VEGFR2+ and median CD133+/VEGFR2+ increased significantly (P = 0.04 and 0.02, respectively). However, the number of colonies and viability of the cells after therapy (as assessed by the MTT assay) was not significantly different compared with the baseline. 

Conclusions: These preliminary results suggest that mineralocorticoid receptor blockade may enhance endothelial progenitor cells recruitment in patients with compensated heart failure.

Background: Previous studies have demonstrated the utility of exercise hemodynamics during right heart catheterization (RHC) in the diagnosis of diastolic dysfunction (DD). Little data exists regarding exercise hemodynamics during RHC in symptomatic systemic sclerosis (SSc) patients. 

Objectives: To assess the added diagnostic value of using exercise hemodynamics during RHC in assessment of patients with symptomatic SSc.

Methods: We performed 22 RHCs in 17 SSc patients with dyspnea and/or pulmonary arterial hypertension (PAH). Exercise was performed in 15 RHCs using isotonic arm exercises while holding a 1 kg weight in each hand. Measurements of pulmonary arterial pressure (PAP), pulmonary arterial wedge pressure (PAWP), and cardiac output (CO) were taken at rest and during peak exercise. 

Results: Normal resting RHC (PAP 22 ± 3 mmHg, PAWP 11 ± 3 mmHg) was found in seven cases. Of these, exercise induced elevation in PAP was found in three (38 ± 7 mmHg), and exercise induced elevation in PAWP was found in four (24 ± 6 mmHg). Elevated resting PAP was found in 15 (41 ± 11 mmHg) with minor changes in exercise. Of the 22 RHCs, elevation of the PAWP was found in 11 (50%), half of which were in response to exercise. 

Conclusions: In symptomatic SSc patients, exercise hemodynamics provides important information on diastolic dysfunction that is not available with non-invasive testing. Findings on exercise RHC can explain patient symptoms in up to 50% of cases. Earlier and more accurate diagnosis of patient symptoms can aid in tailoring the correct therapy for each.

Background: Erysipelas, an acute infection of the dermal and subcutaneous tissue, is normally treated with antibiotics. Previous data indicated that treatment with prednisone in combination with antibiotics results in significant acceleration of the healing phase.

Objectives: To investigate the effectiveness of corticosteroids combined with antibiotics for the treatment of erysipelas.

Methods: A retrospective study was conducted on hospitalized patients diagnosed with erysipelas between 2004 and 2011 at the Department of Dermatology at Sheba Medical Center, Israel. Data included epidemiology, medical background, and course of the disease as documented at admission and during hospitalization. 

Results: Data were collected on 173 patients (66% males) who were divided into two groups: a control group treated with antibiotics only (97 patients) and a study group treated with antibiotics and prednisone (76 patients). The study group presented with a more severe form of erysipelas (bullous) and those patients were hospitalized for a longer period (8.5 vs. 7 days). Nevertheless, the study group exhibited a 71% clinical improvement shortly after being treated with prednisone, without significant side effects. Short-term follow-up revealed more edema in the study group; however, long-term follow-up revealed a higher incidence of erythema and recurrence of erysipelas in the control group. The return to full function was faster in the study group than in the control group. 

Conclusions: Combining prednisone with antibiotics for the treatment of erysipelas should be considered, especially in severe cases. In addition, a prospective double-blind study should be conducted to verify these conclusions.

Background: Acute appendicitis (AA) is one of the most common indications for emergency abdominal surgery.

Objective: To assess the diagnostic and prognostic value of serum bilirubin and liver enzyme levels in the management of acute appendicitis.

Methods: Consecutive emergency department patients referred for a surgical consult for suspected AA were prospectively enrolled in the study. Data regarding demographic, clinical and laboratory results were recorded. Receiver operating characteristic (ROC) curve was performed for all evaluated parameters. Clinical and laboratory markers were evaluated for diagnostic accuracy and correlation to the clinical severity, histology reports, and length of hospital stay.

Results: The study was comprised of 100 consecutive patients. ROC curve analysis revealed white blood cell count, absolute neutrophils count (ANC), C-reactive protein, total-bilirubin and direct-bilirubin levels as significant factors for diagnosis of AA. The combination of serum bilirubin levels, alanine transaminase levels, and ANC yielded the highest area under the curve (0.898, 95% confidence interval 0.835–0.962, P<0.001) with a diagnostic accuracy of 86%. In addition, total and direct bilirubin levels significantly correlated with the severity of appendicitis as described in the operative and pathology reports (P < 0.01). Total and direct bilirubin also significantly correlated with the length of hospital stay (P < 0.01).

Conclusions: Serum bilirubin levels, alone or combined with other markers, may be considered as a clinical marker for AA correlating with disease existence, severity, and length of hospital stay. These findings support the routine use of serum bilirubin levels in the workup of patients with suspected AA.

Background: The distribution of pathology and clinical characteristics of lacrimal gland diseases are different in different areas of the world.

Objectives: To evaluate the incidence rate, patient characteristics, and indications for surgical intervention of lacrimal gland lesions in a tertiary care center in Israel.

Methods: All biopsied or surgically removed lacrimal gland lesions at the Goldschleger Eye Institute from 2009 to 2015 were identified. The following data were collected: age, gender, indications for surgical intervention, diagnosis, treatment, and prognosis.

Results: We evaluated 28 lacrimal gland biopsies from 26 patients (11 men, 15 women). Mean age at biopsy was 47.5 years old. The most common presenting symptoms were: eyelid swollenness (57.14%), ptosis (32.14%), and proptosis (10.71%). All patients underwent computed tomography and magnetic resonance imaging. In 28 cases, infiltrations of the lacrimal gland were found. In nine cases infiltration of muscles or orbital extension were found. The most common pathologies were non-specified inflammation (44.82%), lymphoma (20.68%), and immunoglobulin G4-related disease (10.34%). The treatment was diverse according to the patient diagnosis. Prognosis of lacrimal gland disease was good; however, in five patients the systemic disease progressed.

Conclusions: Lesions of the lacrimal gland comprise a wide variety of pathological findings that require different treatment strategies. Lacrimal gland biopsies enable physicians to precisely recognize the pathology; therefore, it is important to consider this surgical method in any patient with lesions in the lacrimal gland.

Background: Opinions differ as to the need of a lateral radiograph for diagnosing community acquired pneumonia in children referred to the emergency department. A lateral radiograph increases the ionizing radiation burden but at the same time may improve specificity and sensitivity in this population.

Objectives: To determine the value of the frontal and lateral chest radiographs compared to frontal view stand-alone images for the management of children with suspected community acquired pneumonia seen in a pediatric emergency department.

Methods: Chest radiographs from 451 children with clinically suspected pneumonia were retrospectively reviewed. Interpretation of frontal views was compared to interpretation of combined frontal and lateral view, the latter being the gold standard.

Results: Findings consistent with bacterial pneumonia were diagnosed in 94 (20.8%) of the frontal stand-alone radiographs and in 109 (24.2%) of the combined frontal and lateral radiographs. The sensitivity, specificity, positive predictive value, and negative predictive value of the frontal radiograph alone were 86.2%, 93.9%, 81.7%, and 95.5%, respectively. False positive and false negative rates were 15% and 21%, respectively, for the frontal view alone. The number of lateral radiographs needed to diagnose one community acquired pneumonia was 29.

Conclusions: The lateral chest radiograph improves the diagnosis of pediatric community acquired pneumonia to a certain degree and may prevent overtreatment with antibiotics.

Background: Facial rejuvenation using different dermal and sub-dermal injectable compounds is a popular cosmetic procedure which may pose a diagnostic dilemma to the radiologist.

Objectives: To describe the appearance of cosmetic facial fillers on PET-CT.

Methods: All PET-CT exams performed between January 2015 and May 2017 in which findings suggestive of prior facial filler procedures was evident and where anamnestic confirmation with the patient was possible were reviewed.

Results: We describe five females who had undergone facial filler procedures leading to calcifications around the mouth and nasolabial triangle.

Conclusions: Familiarity with the appearance of such cosmetic procedures on PET-CT is of paramount importance in order to avoid misinterpretation of the findings leading to unnecessary apprehension and work-up.

Background: Virtual autopsies by computer tomography (CT) or magnetic resonance imaging can be valuable in cases of unexplained infant death. The radiologist must be familiar with the normal appearance of all the segments of the thoracic aorta in normal and deceased children. A thorough review of the literature revealed no prior articles describing CT changes in the ascending aorta or the aortic arch in pediatric virtual autopsies.

Objectives: To compare the CT appearance of the thoracic aorta in deceased children and in those younger than 3 years of age.

Methods: Hospital registries were searched for cases of unexpected deaths in children younger than 3 years old, with a postmortem CT available, as well as for clinically indicated chest CT in children of the same age during a 5 year period. The ascending aorta (AA), aortic arch (arch), and the descending aorta (DA) diameters were measured. Student's t-tests and Mann–Whitney U-tests were used to compare the two groups.

Results: A total of 64 scans were reviewed: 35 postmortem and 29 performed on living patients. The differences in the diameter and the ratios of the diameter between the AA and the arch, as well as between the arch and the DA in the postmortem and living groups were statistically significant (P < 0.05).

Conclusions: On postmortem CT scans, we found focal tapering of the aortic caliber at the level of the arch between the origin of the brachiocephalic artery and left subclavian artery. This finding should not be misinterpreted as a hypoplastic aortic arch.

Background: Computed tomography (CT) brain perfusion is a relatively new imaging method that can be used to differentiate patients following epileptic seizures in the setting of acute neurological deficits (e.g., hemiparesis, hemiplegia, hemianopsia, aphasia) who arrive at the emergency room with a suspected stroke.

Objectives: To evaluate brain perfusion changes in patients who had an epileptic seizure.

Methods: We retrospectively identified 721 patients who presented at our stroke center between 2012 and 2015 with a suspected acute stroke and underwent examination thorough a stroke protocol, including cerebral CT perfusion (CTP) and CT angiography (CTA) within 8 hours from the onset of symptoms. 

Results: Out of 721 patients, 25 presented with ictal electroencephalography (EEG) findings within 24–72 hours from symptom onset without evidence of vascular occlusion on CTA. While 15 patients had to be excluded from the study due to concomitant brain pathology, we found a specific reduction in cerebral blood volume and cerebral blood flow occurring at the ictal zone, which was identified by a post hoc EEG investigation. 

Conclusions: Our study shows that CTP is an easily accessible tool in emergency department setting for the detection of changes in blood flow dynamics among postictal patients. Thus, we propose the use of CTP in emergency settings to discriminate between postictal changes and acute vascular events. 

 

Background: Maternal cardiac arrest during gestation constitutes a devastating event. Training and anticipant preparedness for prompt action in such cases may save the lives of both the woman and her fetus. 

Objectives: To address a previous Jewish guideline that a woman in advanced pregnancy should not undergo any medical procedure to save the fetus until her condition is stabilized. 

Methods: Current evidence on perimortal cesarean section shows that immediate section during resuscitation provides restoration of the integrity of the mother’s vascular compartment and increases her probability of survival. We analyzed Jewish scriptures from the Talmud and verdicts of the oral law and revealed that the Jewish ethical approach toward late gestational resuscitation was discouraged since it may jeopardize the mother. 

Results: We discuss the pertinent Jewish principles and their application in light of emerging scientific literature on this topic. An example case that led to an early perimortem cesarean delivery and brought about a gratifying, albeit only partially satisfying outcome, is presented, albeit with only a partially satisfying outcome. The arguments that were raised are relevant to such cases and suggest that previous judgments should be reconsidered.  

Conclusions: The Jewish perspective can guide medical personnel to modify and adapt the concrete rules to diverse clinical scenarios in light of current medical knowledge. With scientific data showing that both mother and fetus can prosper from immediate surgical extrication of the baby during resuscitation of the advanced pregnant woman, these morals should dictate training and practice in urgent perimortal cesarean sections whenever feasible.
