Point-of-Care Ultrasound For Differentiating Ileocolic From Small Bowel-Small Bowel Intussusception.

BACKGROUND: Intussusception is a common pediatric emergency. The two types of intussusception are ileocolic intussusception (ICI) and small bowel-small bowel intussusception (SB-SBI), and neither are easily distinguished clinically. ICI requires radiology personnel and potentially surgical assistance for its reduction. SB-SBI is managed expectantly, as many resolve spontaneously. Differentiating between ICI and SB-SBI through point-of-care ultrasound (POCUS) requires an understanding of their salient features. Identification of the correct type of intussusception immediately assists decision making and patient disposition. OBJECTIVE OF THE REVIEW: Our objective was to provide guidance on POCUS technique for intussusception identification, and to review the ultrasound literature differentiating ICI from SB-SBI. METHODS: We systematically searched 3 separate databases and gray literature to identify articles that met our criteria and assessed them for final review. The final articles were graded for quality using The National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies. RESULTS: A total of 858 articles were identified. Six articles were included in the final review. All studies were conducted in pediatric patients in different countries. Most were found to have a fair quality of evidence. The linear transducer is used when evaluating intussusception. Both ICI and SB-SBI are identified easily on POCUS, but they differ sonographically with respect to region within the abdomen, intussusception parameters, lymph nodes, and other salient features seen on real-time video. CONCLUSIONS: ICI and SB-SBI can be identified and differentiated using several sonographic features. POCUS is capable of expeditiously aiding the emergency physician's decision making and disposition when managing intussusception.

Identifying infant hydrocephalus in the emergency department with transfontanellar POCUS.

Hydrocephalus carries significant morbidity in the infant population. Although clinical symptoms are often nonspecific, hydrocephalus is easily identified using transfontanellar sonography. In this review, we provide the emergency physician with a succinct overview of infant hydrocephalus and the point-of-care ultrasound (POCUS) technique for identification of this pathology.

Drop the Knife and Pick Up the Transducer.

Ultrasound has a diagnostic and procedural role when managing breast abscesses. We present the case of an adolescent girl diagnosed with a breast abscess with point-of-care ultrasound who subsequently underwent ultrasound-guided aspiration as a form of definitive management.

Fishhook injury to the eyelid: case report and review of removal methods.

Fishhook injuries are most commonly seen among adult and adolescent anglers. However, children can also be injured by fishhooks. We present the case of an 11-year-old boy with an eyelid fishhook injury that was successfully managed in the emergency department. We review a variety of procedures that can be used to remove embedded fishhooks, including the suitability, advantages, and disadvantages of each method.

A papulopustular, vesicular, crusted rash in a 4-week-old neonate.

Scabies is commonly seen worldwide, in its usual classic form when afflicting older children and adults. However, neonatal scabies is described as its own entity in the literature. We present a case of a 4-week-old infant with a generalized papulopustular, vesicular, and crusted rash who was diagnosed with scabies. We contrast the differing clinical features of neonatal and classic scabies, describe possible mimickers of this diagnostic dilemma, and review current treatment options available for scabies in this very young age group.

Managing Acute Complications Of Sickle Cell Disease In Pediatric Patients.

Sickle cell disease is a chronic hematologic disease with a variety of acute, and often recurring, complications. Vaso-occlusive crisis, a unique but common presentation in sickle cell disease, can be challenging to manage. Acute chest syndrome is the leading cause of death in patients with sickle cell disease, occurring in more than half of patients who are hospitalized with a vaso-occlusive crisis. Uncommon diagnoses in children, such as stroke, priapism, and transient red cell aplasia, occur more frequently in patients with sickle cell disease and necessitate a degree of familiarity with the disease process and its management. Patients with sickle cell trait generally have a benign course, but are also subject to serious complications. This issue provides a current review of evidence-based management of the most common acute complications of sickle cell disease seen in pediatric patients in the emergency department.

Point-of-care Ultrasound for Diagnosis of Abscess in Skin and Soft Tissue Infections.

BACKGROUND: Traditionally, emergency department (ED) physicians rely on their clinical examination to differentiate between cellulitis and abscess when evaluating skin and soft tissue infections (SSTI). Management of an abscess requires incision and drainage, whereas cellulitis generally requires a course of antibiotics. Misdiagnosis often results in unnecessary invasive procedures, sedations (for incision and drainage in pediatric patients), or a return ED visit for failed antibiotic therapy. OBJECTIVE: The objective was to describe the operating characteristics of point-of-care ultrasound (POCUS) compared to clinical examination in identifying abscesses in ED patients with SSTI. METHODS: We systematically searched Medline, Web of Science, EMBASE, CINAHL, and Cochrane Library databases from inception until May 2015. Trials comparing POCUS with clinical examination to identify abscesses when evaluating SSTI in the ED were included. Trials that included intraoral abscesses or abscess drainage in the operating room were excluded. The presence of an abscess was defined by drainage of pus. The absence of an abscess was defined as no pus drainage upon incision and drainage or resolution of SSTI without pus drainage at follow-up. Quality of trials was assessed using the QUADAS-2 tool. Operating characteristics were reported as sensitivity, specificity, positive likelihood ratio (LR+), and negative likelihood ratio (LR-), with their respective 95% confidence intervals (CI). Summary measures were calculated by generating a hierarchical summary receiver operating characteristic (HSROC) model. RESULTS: Of 3,203 references identified, six observational studies (four pediatric trials and two adult trials) with a total of 800 patients were included. Two trials compared clinical examination with clinical examination plus POCUS. The other four trials directly compared clinical examination to POCUS. The POCUS HSROC revealed a sensitivity of 97% (95% CI = 94% to 98%), specificity of 83% (95% CI = 75% to 88%), LR+ of 5.5 (95% CI = 3.7 to 8.2), and LR- of 0.04 (95% CI = 0.02 to 0.08). CONCLUSION: Existing evidence indicates that POCUS is useful in identifying abscess in ED patients with SSTI. In cases where physical examination is equivocal, POCUS can assist physicians to distinguish abscess from cellulitis.
