Seventy-three percent of hips treated with activity modification alone, 80% treated with an injection, and 82% of hips treated with arthroscopic repair met the minimal clinically significant difference (MCID) (P = 0.859). At an average of 36 months follow-up, the majority (78%) of adolescent patients with an acetabular labral tear will achieve the MCID utilizing a graduated management protocol.The lateral capitello-humeral angle (LCHA), which is an index of sagittal alignment of the elbow, has gradually been adopted for the postoperative assessment of radiographic results. However, the normal values and ranges of the LCHA remain unclear. A retrospective cohort study was performed to evaluate the normal values and ranges of the LCHA in a sample of healthy children with even distributions of age, sex and laterality. A total of 168 radiographs of the elbows of healthy children (age range, 0-11 years) with even distributions of age, sex and laterality were reviewed. The primary aim was to analyze the normal values and ranges of the LCHA categorized by age, sex and laterality. The secondary aim was to assess the association of the LCHA with increasing age. The LCHA between sex or laterality in each age category was also compared. The mean LCHA of the 168 patients was 47.1º (range, 27º-63º). There was a weak association between the LCHA and increasing age (r = 0.41). The mean LCHA in females (49.1º) was significantly larger than that in males (45.1º). Significant sex-related differences were observed in age categories between 2 and 7 years. Results of this study will be useful in the postoperative radiographic assessment of sagittal alignment of the elbow in children.
  Neonates with abdominal wall defects are at an increased infection risk because of the defect itself and prolonged neonatal intensive care unit (NICU) stays. Antibiotic prophylaxis until closure of the defect is common. However, infection risk and antibiotic use have not been well quantified in these infants.
 
  A retrospective cohort study of infants with abdominal wall defects (gastroschisis and omphalocele) admitted to a single-center NICU from 2007 to 2018. Demographic and clinical information, including microbiologic studies, antibiotic dosing and surgical care, were collected. Antibiotic use was quantified using days of therapy (DOT) per 1000 patient-days. Sepsis was defined as culture of a pathogen from a normally sterile site.
 
  Seventy-four infants were included; 64 (86%) with gastroschisis and 10 (14%) with omphalocele. Median day of closure was 8 days [interquartile range (IQR) 6-10, range 0-31]. All infants received ≥1 course of antibiotics; median antibiotic DOT/infant was 24.5 (IQR 18-36) for an average of 416.5 DOT per 1000 patient-days. Most antibiotic use was preclosure prophylaxis (44%) and treatment of small intestinal bowel overgrowth (24%).  https://www.selleckchem.com/products/ly2606368.html  Suspected and proven infection accounted for 26% of all antibiotic use. Skin and soft tissue infection (13/74, 18%) and late-onset sepsis (11/74, 15%) were the most common infections; 2 infants had sepsis while on antibiotic prophylaxis. All infants survived to discharge.
 
  Most antibiotic use among infants with abdominal wall defects was prophylactic. Infection on prophylaxis was rare, but 35% of infants had infection after prophylaxis. Improved stewardship strategies are needed for these high-risk infants.

The main clinical indications for hospital admission were vasogenic toxic shock (n = 2), Kawasaki disease (n = 4), and Kawasaki disease shock syndrome (n = 5). The echocardiography findings were abnormal in 63% of cases. All patients had 2 or more organ dysfunctions, and the mortality rate was 18%.
  Bartonella henselae serology is commonly used to diagnose cat-scratch disease (CSD). Titers above a threshold for positivity suggest either a recent or remote infection. Recent infection can be confirmed by a 4-fold rise in the convalescent titer in some cases. Many atypical presentations attributed to CSD utilize a low threshold for positivity without supportive evidence from convalescent sera or supplemental testing, raising a concern for the overdiagnosis of CSD.
 
  We conducted a retrospective chart review of immunocompetent pediatric patients at the Hospital for Sick Children, Toronto, spanning an 11-year period. A total of 154 cases were included with serologic titers ≥1128. These were divided into 3 groups group 1 = 1128, group 2 = 1256, and group 3 ≥ 1512. Cases within groups were evaluated with respect to cat contact, clinical presentation, further testing, and final diagnosis.
 
  One-third of patients with a titer of 1128 had an alternative diagnosis. Most cases with a titer of 1128 or 1256 did not have convalescent serologic testing performed. Within these 2 groups, only 1 case had a 4-fold rise in the convalescent titer. A trend of decreasing number of cases with alternative diagnoses (P = 0.03) and increasing number of cases presenting with regional lymphadenopathy (P = 0.07) was associated with higher titers in group 3 compared with group 1.
 
  Concerns about the serologic diagnosis of CSD include the use of low titers for positivity, incomplete diagnostic evaluation, and the lack of convalescent serologic testing. We propose a clinical guide to assist in managing suspected cases of CSD.

  Healthcare workers (HCWs) are particularly exposed SARS-CoV-2 because they are critical in preventing viral transmission and treating COVID-19 patients. Within HCWs, personnel of intensive care units (ICUs) are at the forefront of treating patients with a severe course of COVID-19 infection and therefore represent an extremely vulnerable group. Thus, our objective is to contribute to establish means of infection control protecting HCWs in the frontline of the current pandemic.
 
  An outbreak of SARS-CoV-2 was detected and contained in a pediatric ICU (PICU). The first positive case was identified with a point-of-care diagnostic system on site. Real-time PCR-based testing systems from self-collected nasopharyngeal samples swabs were used to test for viral RNA of SARS-CoV-2 in the follow-up.

  Positive HCWs were sent into quarantine. Containment measures were implemented including wearing of surgical-masks, physical distancing and systematic testing.
