RESUMO
PURPOSE: Although the association between necrotizing otitis externa (NOE) and diabetes mellitus (DM) is well known, there is little knowledge in regards to the effects of DM and glycemic control on the outcome of NOE. The aim of the study was to determine the effects of DM duration and glycemic control, and in-hospital glycemic control on NOE severity. METHODS: A retrospective case series analysis, including all patients hospitalized between 1990 and 2018 due to NOE were included. Data collected included NOE disease characteristics, duration of DM, DM-associated comorbidities, glycated hemoglobin (HbA1c), urine microalbumin and in-hospital blood glucose measurements. Disease severity was defined based on duration of hospitalization (above or below 20 days) and need for surgery. RESULTS: Eighty-nine patients were included in the study. Eighty-three patients (94.3%) had DM. Preadmission HbA1c was 8.13% (5.8-12.6%). Forty-nine patients (65.5%) had mean blood glucose of ≥ 140 mg/dL and 26 (34.5%) had ≤ 140 mg/dL. DM duration was 157.88 months among NOE patients who required surgery, and 127.6 months among patients who were treated conservatively (p value 0.25). HbA1c in patients hospitalized < 20 days was 7.6%, and 8.7% among NOE hospitalized ≥ 20 days (p value 0.027). Seven patients with mean blood glucose of ≤ 140 mg/dL had Pseudomonas Aeruginosa (PA-NOE) (26.7%), in comparison to 25 (51.0%) with mean blood glucose measurement of ≥ 140 mg/dL (p = 0.045). CONCLUSIONS: HbA1c at admission is associated with longer hospitalization duration among NOE patients. Mean blood glucose during hospitalization was associated with a higher likelihood of PA infection, however, it had no effect on disease outcome.

BACKGROUND: One in four older adults in the Emergency Department (ED) suffers from severe cognitive impairment, creating great difficulty for the emergency physicians who determine the urgency of their patients' condition, which informs decisions regarding discharge or hospitalization. OBJECTIVE: Our objective was to determine whether modified shock index (MSI) can be a clinical mortality and hospitalization predictor when applied to older patients with dementia in the ED. METHODS: Included in the research were all patients with dementia, > 65 years old, who arrived at the Soroka University Medical Center ED during 2014-2017. The population was divided into three groups according to their MSI score, calculated as heart rate/mean arterial pressure: MSI < 0.7; 0.7 > MSI < 1.3; and MSI > 1.3. We performed multivariable logistic regression as a predictor of death within 30 days, Cox analysis for number of days to death, and a negative binominal regression for predicting the number of admission days. RESULTS: Included were 1437 patients diagnosed with dementia. Patients with an MSI > 1.3 vs. those with MSI < 0.7 had an odds ratio of 8.23 (95% confidence interval [CI] 4.64-4.54) for mortality within 30 days, increased mortality risk within 180 days (hazard ratio 4.42; 95% CI 2.64-7.41), and longer hospitalization duration (incidence rate ratio 1.8; 95% CI 1.32-2.45). CONCLUSIONS: High MSI scores were associated with high mortality rates and longer hospitalization duration for patients diagnosed with dementia who were > 65 years old. We suggest performing prospective studies utilizing the MSI score as an indicator in ED triage settings to classify patients with dementia by their severity of risk, to determine if this benefits health, minimizes expenses, and prevents unnecessary hospitalizations.

PURPOSE: High-resolution temporal bone computer tomography (HRTBCT) is the most common initial radiological modality used for the assessment of necrotizing otitis externa (NOE). OBJECTIVES: (1) To compare the extension of disease, as seen on HRTBCT, in patients with NOE caused by different pathogens and (2) assess whether radiological findings may suggest the offending pathogen in cases of sterile-NOE. METHODS: All NOE patients were hospitalized between 1990 and 2018. All patients underwent HRTBCT at admission. Three groups (fungus-NOE, PA-NOE and sterile-NOE) comprising of ten patients each were randomly selected. HRTBCT was reevaluated by a senior radiologist. Thirteen radiological subsites were selected for reevaluation. RESULTS: All patients in the fungal-NOE group complained of otalgia, compared to nine in the sterile-NOE and six in the PA-NOE groups (p value = 0.044). External ear canal edema and granulation tissue were the most common findings in all groups. Surgery was performed in five patients in the fungal-NOE and PA-NOE and three in the sterile-NOE group (p value = > 0.05). Radiological findings indicating severe bone erosion within the EEC was seen in all patients but 3 (p value = > 0.05). Severe TMJ erosion was seen in one patient within the fungal-NOE and PA-NOE group (p value = > 0.05). When mild and severe involvement were combined, TMJ bone erosion was seen in four patients in the fungal-NOE and only in one patient in the PA-NOE (p = 0.04). CONCLUSIONS: TMJ involvement may be more common in fungal disease, suggesting a different spreading pathway, as opposed to PA-NOE. Accordingly, TMJ involvement on HRTBCT may justify antifungal treatment in sterile culture-NOE.

BACKGROUND: The use of cardiac point of care ultra-sound is rapidly growing and so is the demand for quality POCUS teaching. POCUS teaching is usually conducted in small groups requiring much space and equipment. This study attempts to test whether providing access to an E-learning module as an adjunct to a cardiac POCUS course can increase students' image acquisition skills. This will show POCUS teaching can improve significantly without having to invest a significant amount of resources. METHODS: Medical students (N = 125) were divided into two groups and had undergone a hands-on Cardiac POCUS course before their internal clerkship. During the clerkship, members of both groups got to practice their POCUS skills in the internal wards. One group was provided with accounts to a cardiac POCUS teaching E-learning platform (eMedical Academy©). After limited time for self- practice, both groups underwent a pre-validated ultrasound examination. The two groups' test results were then compared for each POCUS view and for the total exam score. RESULTS: The E-learning group performed significantly better than the course-only group in the 6-min exam total score, and at acquiring the following views: parasternal long axis view, apical four-chamber view, and the inferior vena cava view. CONCLUSION: E-learning platforms can be an efficient tool for improving cardiac POCUS teaching and maintaining POCUS skills. Using it as a supplement to a hands-on course provides better POCUS skills without the need of extra hands-on teaching.

OBJECTIVES: To evaluate the impact of the pneumococcal conjugate vaccines (PCVs) introduction on the orbital complications of acute rhino-sinusitis (OC-ARS). METHODS: A retrospective cohort study of all pediatric patients with OC-ARS during the period 2002-2019. Data included clinical, demographic, laboratory, and microbiology findings. Patients were divided into three groups: before PCV7 introduction (group 1), after PCV7 and before PCV13 (group 2), and after PCV13 (group 3). RESULTS: Of 265 enrolled patients, 117, 39, and 109 were assigned to groups 1, 2, and 3. During the study period, a significant decrease was recorded in the percentages of patients in Chandler classification severity category 1, with an increase in patients in category 3 (P = 0.011). The yearly incidence of OC-ARS decreased from 12.64 cases per 100,000 population in 2002 to 5.56 per 100,000 in 2008, and 2.99 per 100,000 in 2019 (P < 0.001). Patients aged 0-4 years showed a dramatic decrease from 29 cases per 100,000 population in 2002 to 4.27 per 100,000 in 2019 (P < 0.001). The pathogens retrieved from all cultures performed were Streptococcus pneumoniae (32.5%), non-typeable Haemophilus influenzae (27.5%), Streptococcus Species, (12.5%), and Staphylococcus aureus (20%), with no changes in distribution during the study periods. Surgery was performed in 28 (10.6%) patients. CONCLUSIONS: A significant decrease was seen in the overall incidence of OC-ARS, mainly attributable to the decrease in patients aged 0-4 years. An increase was recorded in the severity of the disease following PCVs introduction.
RESUMO
The most common snake in Israel, responsible for most snakebites is Vipera palaestinae (VP). Envenomation signs and symptoms vary from local manifestations to systemic reactions that may end with death. Antivenom treatment, given to high-risk patients, reduces complications and mortality but carries risks. As of now, there is no standardized protocol for adults bitten by VP based on objective clinical and laboratory findings. We conducted A retrospective analysis of 159 patients admitted to two large tertiary care institutions in the center (Hadassah University Medical Center) and south (Soroka University Medical Center) of Israel with Vipera palaestinae bites during 1990-2017. Epidemiological and clinical data were extracted, and the patients were divided into two groups based on hospitalization time (over or under 48 h). 159 patients were included in this study. The average hospitalization time was 66.1 h, with 49.7% of patients admitted over 48 h. The main factors that statistically correlated with a longer hospitalization time were: Male gender, lower extremity bite, platelets lower than 150 K at presentation, leukocyte count of over 10 K at presentation and elevated D-Dimer levels. This study provides factors which are associated with a severe VP envenomation. These clinical or laboratory findings (along with accompanying clinical symptoms) are associated with a higher risk of a prolonged hospitalization with more complications and may require a more intensive treatment and monitoring.

PURPOSE: To investigate whether point of care ultrasound can improve central venous catheter tip positioning. MATERIAL AND METHODS: A single center retrospective case control study. We compared the precision of central venous catheter tip positioning between two intensive care units while in only one of the units, we used point of care ultrasound for guidewire identification. RESULTS: 207 cases in which central venous catheter was inserted using point of care ultrasound guided method, compared to 192 controls. The primary outcome of correct placement of the central venous catheter tip was significantly higher in the point of care ultrasound guided group (97.6% vs 88.0% p = 0.001). Central venous catheter tip was located too low among 12% of patients in the control group while in only 2.4% of patients in the point of care ultrasound group (p = 0.001). Logistics regression analysis revealed that the correct placement of central venous catheter tip in the point of care ultrasound group versus the control group had an odds ratio of 4.9 (CI 1.6-14.5 P = 0.004). CONCLUSION: Point of care ultrasound for guidewire identification and localization, while inserting central venous catheter from all upper torso sites, improves precision positioning.

BACKGROUND: Central Venous Catheters (CVC) are being used in both intensive care units and general wards for multiple purposes. A previous study Galante et al. (2017) observed that during CVC insertion through Subclavian Vein (SCV) or the Internal Jugular Vein (IJV) the guidewire is sometimes advanced to the Inferior Vena Cava (IVC), and at other times to the right atrium. The rate of IVC wire cannulation and the association with side and point of insertion is unknown. OBJECTIVE: In this study, we describe guidewire migration location during real time CVC cannulation (right atrium versus IVC) and report the association between the insertion site and side of the CVC and the location of guidewire migration, Right Atrium (RA)/Right Ventricle (RV) versus IVC guidewire migration. METHODS: This is a retrospective study in the medical intensive care unit among patients that have received CVC during the study years 2014-2020. The rate of IVC versus right atrium/right ventricle wire migration during the procedure were analyzed. The association between the side and point of CVC insertion and the wire migration site was analyzed as well. RESULTS: One hundred and sixty-six patients were enrolled. 33.7% of wires migrated to the IVC and 66.3% to the versus right atrium/right ventricle. The rate of wire migration to the IVC was similar in the IJV site and the SCV site. There was no association between the side of CVC insertion and wire migration to the IVC. CONCLUSION: About a third of all wire migrations, during CVC Seldinger technique insertion, were identified in the IVC, with no potential for wire associated arrhythmia. There was no association between CVC insertion point (SCV versus IJV) nor the side of insertion and the site of guidewire migration.

BACKGROUND: Patients with primary hyperparathyroidism (PHPT) treated surgically occasionally have normalized calcium, but persistently high parathyroid hormone (PTH). We hypothesized that a possible explanation for this phenomenon is an underlying hyperplasia rather than adenoma. METHODS: Retrospective cohort of patients who underwent parathyroidectomy for PHPT with biopsy of a normal-appearing parathyroid gland were included. Cellularity level of each biopsy and of the adenoma's rim was determined. RESULTS: Forty-seven patients were included. Of them, 19 (40%) had postoperative normocalcemia but elevated PTH. There was no correlation between cellularity either in the rim or of the normal-appearing parathyroid gland and postoperative PTH. The postoperative high PTH group had higher preoperative PTH (P = 0.001) and larger adenomas (P = 0.025). CONCLUSIONS: High PTH levels after successful parathyroidectomy in patients with primary hyperparathyroidism do not appear to result from underlying hyperplasia. A possible alternative explanation is that these patients have a higher preoperative burden of disease.
RESUMO
BACKGROUND: The benefits of Point of Care Ultrasound (POCUS) are well established in the literature. As it is an operator-dependent modality, the operator is required to be skilled in obtaining and interpreting images. Physicians who are not trained in POCUS attend courses to acquire the basics in this field. The effectiveness of such short POCUS courses on daily POCUS utilization is unknown. We sought to measure the change in POCUS utilization after practicing physicians attended short POCUS courses. METHODS: A 13-statements questionnaire was sent to physicians who attended POCUS courses conducted at the Soroka University Medical Center between the years 2014-2018. Our primary objective was to compare pre-course and post-course POCUS utilization. Secondary objectives included understanding the course graduates' perceived effect of POCUS on diagnosis, the frequency of ultrasound utilization and time to effective therapy. RESULTS: 212 residents and specialists received the questionnaire between 2014-2018; 116 responded (response rate of 54.7%). 72 (62.1%) participants were male, 64 (55.2%) were residents, 49 (42.3%) were specialists, 3 (2.5%) participants did not state their career status. 90 (77.6%) participants declared moderate use or multiple ultrasound use six months to four years from the POCUS course, compared to a rate of 'no use at all' and 'minimal use of 84.9% before the course. 98 participants [84.4% CI 77.8%, 91.0%] agree and strongly agree that a short POCUS course may improve diagnostic skills and 76.7% [CI 69.0%, 84.3%] agree and strongly agree that the POCUS course may shorten time to diagnosis and reduce morbidity. CONCLUSIONS: Our short POCUS course significantly increases bedside ultrasound utilization by physicians from different fields even 4 years from course completion. Course graduates strongly agreed that incorporating POCUS into their clinical practice improves patient care. Such courses should be offered to residents and senior physicians to close the existing gap in POCUS knowledge among practicing physicians.

Numerous studies emphasize the diagnostic importance of point-of-care ultrasound (POCUS), but the level of evidence remains low as most data are gathered from observational studies. We conducted a pilot, randomized controlled trial to evaluate the effect of POCUS exam on medical patient's management and clinical outcomes. Patients presenting with chest pain or dyspnea were enrolled and randomly allocated to an early POCUS scan group and a control group. POCUS assessment, within 24 h of internal ward admission, was conducted only for the intervention group. The primary outcome was time to correct diagnosis. Secondary outcomes included time to appropriate treatment, POCUS-related rate of primary diagnosis alteration and new clinically relevant findings and time to hospital discharge. Sixty patients were enrolled. Thirty patients were randomly allocated to each study arm. The POCUS exam revealed clinically relevant findings among 79% of patients and led to alteration of the primary diagnosis among 28% of patients. Time to appropriate treatment was significantly shorter among patients in the POCUS group compared with the control group (median time of 5 h [95% confidence interval: 0.5-9] vs. 24 h [95% CI: 19-29] pâ¯=â¯0.014). The time needed to achieve correct diagnosis by the primary team was shorter in the POCUS group compared with the control group, yet it did not reach statistical significance (median time of 24 h [95% CI: 18-30] vs. 48 h [95% CI: 20-76], pâ¯=â¯0.12). These results indicate that POCUS assessment conducted early among patients with dyspnea or chest pain improves diagnostic accuracy and shortens significantly the time to appropriate treatment.

BACKGROUND: Point-of-care ultrasonography (PoCUS) is a rapidly evolving discipline that aims to train non-cardiologists, non-radiologists clinicians in performing bedside ultrasound to guide clinical decision. Training of PoCUS is challenging, time-consuming and requires large amount of resources. The objective of our study was to evaluate if this training process can be simplified by allowing medical students self-train themselves with a web-based cardiac ultrasound software. METHODS: A prospective, single blinded, cohort study, comparing performance of 29 medical students in performing a six-minutes cardiac ultrasound exam. Students were divided into two groups: self-learning group, using a combination of E-learning software and self-practice using pocket ultrasound device compared to formal, frontal cardiac ultrasound course. RESULTS: All 29 students completed their designated courses and performed the six-minutes exam: 20 students participated in the frontal cardiac ultrasound course and 9 completed the self-learning course. The median (Q1,Q3) test score for the self-learning group was higher than the frontal course group score, 18 (15,19) versus 15 (12,19.5), respectively. Nevertheless, no statistically significant difference was found between the two study groups (p = 0.478). All students in the self-learning course group (9/9, 100%) and 16 (16/20, 80%) of students in the frontal ultrasound course group obtained correct alignment of the parasternal long axis view (p = 0.280). CONCLUSIONS: Self-learning students combining E-learning software with self-practice cardiac ultrasound were as good as students who received a validated, bedside, frontal cardiac ultrasound course. Our findings suggest that independent cardiac ultrasound learning, combining utilization of E-learning software and self-practice, is feasible. Self-E- learning of cardiac ultrasound may serve as an important, cost-effective adjunct to heavily resource consuming traditional teaching.
