Characteristics, outcomes, and 30-day readmissions following pediatric extracorporeal membrane oxygenation in the United States: A Nationwide Readmissions Database study.

OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) is an increasingly used mode of critical care support for pediatric patients refractory to conventional therapy. We evaluated the characteristics, outcomes, and readmissions rates for pediatric ECMO in the United States. METHODS: Data was extracted from the Nationwide Readmissions Database, a database designed to support national readmissions analyses, for patients aged 1-18 years undergoing ECMO between 2012-2018. Baseline demographics, comorbidities, and characteristics were identified using International Classification of Diseases codes. RESULTS: Out of 897,117 index pediatric hospitalizations, 3706 patients underwent ECMO [median age 9 years (IQR 2,15); 51.6% males]. 2246 (60.6%) patients survived to hospital discharge, with a 30-day readmissions rate of 17% among survivors. Cardiac conditions associated with ECMO were congenital heart disease (25.3%), cardiogenic shock (23.6%), and congestive heart failure (16.2%). The common respiratory associations were sepsis (36.2%), pneumonia (35.6%), and asthma (15.4%). Patients who survived were more likely to have diagnoses of asthma, bronchiolitis, myocarditis, pneumonia, and sepsis. Acute kidney injury (51.5%), disseminated intravascular coagulation (22.5%), and surgical site bleeding (12.7%) were the commonly associated complications. The trend for yearly survival rates was not statistically significant (linear p-trend = 0.38). CONCLUSIONS: Pediatric ECMO continues to be associated with notable mortality and complication rates. We did not observe a meaningful trend for the yearly survival rates over the study period, and over one-sixth of survivors were readmitted within 30-days. More research is needed to identify patients at high risk of mortality and readmissions, to help target resources more efficiently and improve survival.

Thrombotic Occlusion of Ectatic Coronary Arteries in a Young Patient.

Multiple rounds of aspiration thrombectomy followed by balloon angioplasty of the left anterior descending (LAD) failed to completely restore the flow into the distal LAD secondary to re-occlusion from thrombus formation.

Atypical Presentation of C. Difficile Infection: Report of a Case with Literature Review.

Clostridium difficile (C. difficile) is a gram-positive, obligate, anaerobic spore-forming bacillus first reported by Hall and O'Toole in 1935. It occurs mostly after antibiotic use and invariably presents with watery diarrhea. We describe an atypical presentation of C. difficile in a 64-year-old Caucasian female who presented to the our emergency department with abdominal pain, nausea, and vomiting for one day. A complete blood count revealed leukocytosis 30 x 10(9)/L and a subsequent computed tomography (CT) scan of the abdomen and the pelvis, showed fluid filled small bowel loops consistent with enteritis. Her presentation was unusual for lack of diarrhea, the hallmark of C. difficile infection. She was admitted and treated with oral vancomycin. The polymerase chain reaction (PCR) value in the stool for C. difficile was positive. The patient responded very well: her abdominal pain resolved and leukocyte count normalized after a few doses of vancomycin (125 mg po qid). The patient's progress was followed in our clinic for the last three months.

A Case of Purple Urine Bag Syndrome in a Spastic Partial Quadriplegic Male.

Purple bag urine syndrome (PUBS) is a benign and unique phenomenon of the urine turning a deep violet color within the urinary catheter tubing and bag. This phenomenon is commonly encountered in patients indicated with long-term catheter placement or, in certain conditions like chronic constipation, alkaline urine, limited ambulation, and, in terms of gender distribution, the female sex, predominates. PUBS gets its name from a unique phenomenon that takes places inside the gut where tryptophan (an amino acid) is metabolized, producing blue and red hues which together emanate a deep violet color. Here, the case of a middle-aged male patient with a suprapubic catheter in situ, following trauma causing spastic partial quadriplegia, is being presented with PUBS due to UTI secondary to Proteus vulgaris. The risk factors, in this case, include chronic constipation and recurrent urinary tract infections (UTIs).​.
