Pericardial effusion is a potentially lethal condition. If it is discovered early, it can be treated by pericardiocentesis under controlled condition with imaging by experienced care providers. If it is diagnosed at a later stage with clinical compromise, then an emergent procedure might be necessary. Since it is encountered infrequently, many providers may have little or no experience in managing the condition and performing a life-saving pericardiocentesis. This is a technical report that describes the creation of a neonatal model for pericardiocentesis. This is a high-fidelity, low-cost model that is simple to create. Materials that are inexpensive and easy to obtain are utilized to make the model. Neonatal care providers, including residents, fellows, nurse practitioners, physician assistants, and attendings, can practice with this model. In some medical centers, an echocardiogram or bedside ultrasound is available to guide needle insertion; however, practicing the procedure on a model provides valuable experience. This model is designed to teach the performance of unguided pericardiocentesis without the use of simultaneous imaging. Included with this technical report are a supply list, a checklist, and a suggested scenario that can be used in association with this model. In this article, we have discussed our own experience and described lessons learned about training neonatal care providers in pericardiocentesis.Trauma is the leading cause of mortality in those aged 1-19, with hemorrhage accounting for up to 40% of all trauma deaths. Manufactured tourniquets are recommended for the control of life-threatening extremity hemorrhage in adults but their use in the pediatric population requires further investigation. We performed a systematic review to evaluate the most appropriate tourniquet design for use in the pediatric population. A literature search of Embase and the Cochran databases of trials and systematic reviews on October 1, 2020 identified 454 unique references, of which 15 were included for full-text screening. Two single-arm observational studies with a high risk of bias evaluated the use of windlass tourniquets in the pediatric population (73 patients, age 2-16 years). The certainty of the evidence was very low. In both studies, conducted on uninjured extremities, the use of a manufactured windlass tourniquet, specifically the Combat Application Tourniquet (C-A-T®) Generation 7, led to the cessation of Doppler detected pulses in 71/71 (100%) of upper extremities and 69/73 (94.5%) of lower extremities. Of the four failures, one participant withdrew due to pain and three tourniquet applications failed to occlude pulses after three turns of the windlass. No controls were used for comparison. In conclusion, two observational studies demonstrated that windlass tourniquets were able to abolish distal pulses in children as young as two years of age and with a minimum limb circumference of 13 cm. These preliminary findings may be helpful for organizations in the creation of guidelines for the management of life-threatening extremity bleeding in children.Renal medullary carcinoma (RMC) is an aggressive and rare malignancy that usually presents in adolescents and young adults with sickle cell disease. Herein, we describe a case of a white male with an unknown sickle cell trait, who presented with left iliac fossa pain, without any other finding that suggested renal neoplasia. Imaging findings were a renal mass of central location with caliectasis, renal hilar adenopathy, and paraaortic lymphadenopathy. Biopsy confirmed an RMC diagnosis. RMC diagnosis requires clinical suspicion in sickle cell patients who present with pain and hematuria. Imaging shows a central mass, with an infiltrative appearance, frequently associated with calyx's dilation and lymphadenopathy. Prognosis is poor in spite of the treatment.Objective The aim of this study was to assess the impact of intraoperative disruptions on surgeons' workload and performance during percutaneous nephrolithotomy (PCNL). Materials and methods A structured and standardized tool was used to identify disruptions and interferences that occurred during 33 PCNL procedures. The surgical steps during PCNL were divided into four phases ureteric catheter placement (phase I), puncture and tract dilation (phase II), intra-calyceal navigation and stone fragmentation (phase III), and tube placement (phase IV). Surgeons' workload was evaluated using a validated tool Surgery Task Load Index (SURG-TLX), and correlated with the mean observed intraoperative disruptions. All operating team members evaluated the teamwork immediately after the procedure. Statistical analysis was performed using SPSS Statistics version 22 (IBM, Armonk, NY). Results A total of 1,897 disturbances were observed, with an average of 57.48 ± 16.36 disruptions per case. The largest number of disruptions occurred during phase III of PCNL (32.06 ± 14.12). The most common cause of the disruption was people entering or exiting the operating room (OR) (29.1 ± 10.03/case), followed by the ringing of phones or pagers (6.42 ± 2.4). The mean observed intraoperative disruptions were significantly associated with the operating surgeon's mental workload, and it had a significant impact on all domains of surgeons' mental workload as measured by SURG-TLX. Compared to other team members, surgeons' assistants experienced an inferior sense of teamwork (r=-0.433; p=0.012). Conclusion Significant intraoperative disruptions were observed during PCNL. They were observed to directly correlate with the surgeon's workload and had a detrimental effect on teamwork. Improving OR dynamics by reducing unnecessary disruptions would help establish an efficient and smooth surgical work environment for safe surgical care.Introduction Falls are the leading cause of injury-related death among older adults according to the Centers for Disease Control and Prevention (CDC). The Falls Efficacy Scale (FES) and Vulnerable Elder Survey (VES-13) are validated screening tools used to assess concern of falling, health deterioration and functional decline. read more We set out to determine if the FES or VES-13 could serve as a predictor of falls among older adults in the Emergency Department (ED) setting. Methods This prospective pilot cohort study was conducted at a Level 1 Trauma Center. ED patients aged ≥65 were eligible for the study if they had a mechanical fall risk defined by CDC criteria. After consent and enrollment, FES and the VES surveys were completed. Participants were followed by phone quarterly, and results of the one-year follow-up self-report of fall history described. Results There were 200 subjects enrolled and after excluding those that were withdrawn, deceased, or lost to follow-up, 184 were available for analysis of their follow-up visit at 12 months.
