Surgical Resection of Bilateral Polycystic Ovaries Causing Ureteral Obstruction.

Ovarian cysts in adolescents are typically managed conservatively given the low rate of malignancy and the cysts typically regress over time. We present a case of a 14 year-old female with large bilateral adnexal cysts causing ureteral obstruction which was successfully treated with surgical resection and ensuring maximum preservation of ovarian tissue.

Management of Hidden Cutaneous Melanoma of the Umbilicus.

Melanoma is currently the fifth most common cancer in the United States (US) and most often develop on areas that have increased sun exposure, such as the arms, legs, back or face. The incidence of primary cutaneous melanoma increases each year and curative treatment improves with earlier detection of disease. Primary cutaneous umbilical melanoma is extremely rare with as few as 46 cases reported worldwide. As a result, limited literature is available regarding the management of tumors originating in the umbilicus. By evaluating uncommon areas such as the umbilicus, earlier detection and possible intervention can be provided. We present a rare case of a 33-year-old female with a primary cutaneous melanoma of the umbilicus successfully treated with wide local excision (WLE) and sentinel lymph node biopsy (SLNB).

Population Density and Triage of Pediatric Firearm Injuries in a Rural Trauma System.

BACKGROUND: Rural pediatric firearm injuries require regional pediatric and trauma expertise. We evaluated county-level population density associations with transport, hospital interventions, and patient outcomes at a Level I pediatric trauma center serving a rural, statewide catchment area. MATERIAL AND METHODS: The trauma registry of the only in-state pediatric trauma center was reviewed for firearm injuries in patients < 18 between 1/2013 and 3/2020. County-level population density was classified according to the United States Office of Management and Budget definitions for rural, micropolitan, and metropolitan areas. RESULTS: 364 patients were identified, including 7 patients who were re-injured. Mean age was 11.3 ± 4.5 y and patients were 79.4% male. 59.3% were transferred from a referring hospital. Median injury severity score was 5 (IQR 1-10); 88.0% required trauma center admission, and 48.2% required operative intervention. 7.4% were injured in a rural county, 46.4% in a micropolitan county, and 46.2% in a metropolitan county. Patients from rural counties were more likely to be unintentionally injured (72.0%) than those from micropolitan (54.4%) or metropolitan counties (44.0%, P = .04). While need for inpatient admission and length of stay were similar, those transported from rural counties had significantly longer transport times (P < .01) and less frequent need for operative intervention (P = .03), as well as trends toward lower injury severity (P = .08) and mortality (P = .06). CONCLUSION: Management of pediatric firearm injury is a unique challenge with significant regional variability. Opportunities exist for outreach, telehealth, and decision support to ensure equitable distribution of resources in rural trauma systems. LEVEL OF EVIDENCE: Epidemiological, Level III.

Functional status of heart transplant recipients predicts survival.

INTRODUCTION: Recipient functional status prior to transplantation can significantly impact post-transplant survival. METHODS: The United Network for Organ Sharing database was queried for adult heart transplants including data on functional capacity and from February 1, 2005 to March 1, 2021; there were 32 875 cases included. The four functional categories studied were based on adult daily activities of living and were separated into total assistance required, some assistance required, no assistance required, and near death. Survival outcomes were compared for recipient's pretransplant level of functional status versus those with near death status. These were compared using adjusted logistic regression (odds of death at 30 days and 1 year) and conditional Cox models (overall survival and time until post-transplant rejection). All models were adjusted for donor age, sex, ethnicity, ischemic time, as well as recipient age, sex, ethnicity, length of stay, UNOS region, ventricular assist device, creatinine, days on the waiting list, and status at transplant. RESULTS: There were 12 953 recipients classified as "near death" or "severely disabled"; 7711 "required total assistance in daily living", 7,328 "needed some", and 4883 "needed none". In adjusted models, the probabilities of death for the lowest functioning groups within 30 days and 1 year were 5% and 10%, respectively. Those "requiring total assistance" had analogous probabilities of 3% (OR = 0.58; p < 0.001) and 9% (OR = 0.81; p < 0.001). Those "requiring some assistance" had probabilities of 3% (OR = 0.56; p < 0.001) and 9% (OR = 0.74; p < 0.001). Lastly, those "requiring no assistance" had probabilities of death of 2% (OR = 0.35; p < 0.001) and 7% (OR = 0.63; p < 0.001). CONCLUSION: Recipient functional status assessed pre-transplant and recorded in the UNOS database is a strong predictor of post-transplant survival.

Impella 5.0: An intermediate strategy for bridging a patient from infected durable LVAD to cardiac transplant.

Cardiac transplant remains the gold-standard treatment for end-stage heart failure more than 50 years after the procedure was first pioneered. The number of transplant operations performed annually has been limited by the global imbalance of donor organs to recipients. This imbalance helped fuel the development of left ventricular assist devices (LVADs) first as a bridge to cardiac transplant and subsequently as destination therapy. Driveline infection is one of several problems that continue to plague LVADs through several generations of improvement. We present a patient with an infected LVAD driveline exit site that progressed to mediastinitis, pericardial and pump infection. The device was explanted, and the patient supported with an axillary Impella 5.0 as a bridge until the time of transplant. An Impella 5.0 (or 5.5) can be used as an intermediate tool to be able to explant an infected LVAD, with mediastinitis, allowing the patient to clear the infection, and prepare the patient for transplant free of infection. METHODS: The patient consented to the study and case report. The patient signed an informed consent and permission for publication.

Better together: a reappraisal of heterotopic heart transplantation.

Heterotopic heart transplantation (HHT) is rare in the modern era. When used as a biologic left ventricular assist, HHT provides pulsatile flow, supports the left ventricle with a physiologic cardiac output, responds to humoral stimuli, and with modern immunosuppression may offer long-term untethered survival. This study was undertaken to compare survival of HHT with orthotopic heart transplantation (OHT) to assess its viability in the modern era. In the United Network for Organ Sharing database, from January 1999 to December 2020, there were 27691 bicaval OHT, 13836 biatrial OHT, 1271 total OHT, and 51 HHT with sufficient follow-up. Survival was analyzed using restricted mean survival time (RMST) through 4 years as the outcome. In the first 4 years after transplant, compared with HHT, differences in RMST were 0.1 years (99% CI: -0.4 to 0.5 years) for bicaval OHT, 0.0 years (99% CI: -0.4 to 0.5 years) for biatrial OHT, and 0.0 years (99% CI: -0.5 to 0.4 years) for total OHT. In this cohort, survival was indistinguishable between HHT and OHT recipients in the first four years. Thus, HHT might be a viable alternative to durable mechanical circulatory assist particularly with size mismatched grafts or for patients with refractory pulmonary hypertension.

Surgical Control of Bleeding From Ovarian Torsion in the Setting of Immune Thrombocytopenic Purpura Without Splenectomy.

Immune thrombocytopenic purpura (ITP) is a disorder caused by autoimmune antibodies which target glycoprotein IIb/IIIa complex or other platelet membrane antigens leading to platelet destruction. These platelets are then cleared by the spleen resulting in thrombocytopenia. Immune thrombocytopenic purpura affects about 1 to 6.4 cases in 100 000 children making it one of the most common causes of symptomatic thrombocytopenia in the pediatric population. It is rare that children or adolescents present with serious bleeding due to ITP. Common presentations include petechiae, bleeding gums, or bruising. Bleeding requiring hospitalization or transfusions is unusual and only occurs in approximately 5% of children. Even more uncommon is the presentation of severe bleeding complications requiring surgery for resolution. We present a case of a 17-year-old girl with acute ITP complicated by intraperitoneal hemorrhage and refractory thrombocytopenia due to ovarian cyst requiring oophorectomy.

Does pediatric heart transplant survival differ with various cardiac preservation solutions?

BACKGROUND: Few studies directly compare outcomes between the most commonly used preservation solutions in pediatric heart transplantation in a large cohort of recipients. The purpose of this study is to investigate the effect of cardiac preservation solution on survival in pediatric heart transplant recipients. METHODS: The United Network for Organ Sharing (UNOS) database was retrospectively reviewed from 01/2004-03/2018 for pediatric donor hearts. Saline, University of Wisconsin (UW), "cardioplegia," Celsior, and Custodiol preservation solutions were evaluated. The primary endpoints were recipient survival at 30 days, 1 year, and long term. RESULTS: After exclusion criteria, 3012 recipients had preservation solution data available. The most common preservation solution used was UW in 1203 patients (40%), followed by Celsior in 542 (18%), cardioplegia in 461 (15%), saline in 408 (14%), and Custodiol in 398 (13%). Survival of recipients whose donor hearts were procured with UW was as follows: 97%-30 day, 92%-1 year; Celsior: 97%-30 day, 92%-1 year; cardioplegia: 97%-30 day, 91%-1 year; saline: 97%-30 day, 91%-1 year; and Custodiol: 96%-30 day and 92%-1 year. Analysis of Cox models for 30-day and long-term survival revealed no statistical differences when comparing UW to Celsior (p = .333), cardioplegia (p = .914), saline (p = .980), or Custodiol (p = .642) in adjusted models. CONCLUSIONS: There were no significant differences in 30-day or 1-year survival detected between commonly used preservation solutions in the pediatric heart transplant population.
