RESUMO
Purpose: To determine the incidence, mortality, stage, and recovery of acute kidney injury (AKI) in COVID-19 patients and further analyze the effect of patient demographics and comorbidities on AKI incidence. Study Design: Our study looked at 1545 charts of patients over 18 years old who presented to BronxCare Hospital in NY with a positive SARS-CoV-2 PCR test. Using the KDIGO criteria, any patient presenting with a creatinine of 1.5 times the baseline or that had an increase in creatinine of 0.3mg/dL in 48 hours was diagnosed with AKI. Pregnant patients, patients with end-stage renal disease (ESRD), and patients with a history of renal transplant were excluded. Results: The incidence of AKI in COVID-19 patients was 39% (608), and the mortality rate was 58.2% (354). Of the 254 survivors, 74.8% recovered. Moreover, 42.6% (259) of patients with AKI were admitted to the ICU. Twenty-six of our patients received hemodialysis during admission. There was a statistically significant association between AKI and age, race, hypertension (HTN), diabetes mellitus (DM), hepatitis C (HCV), congestive heart failure (CHF), CKD, patient outcome, and days spent in the hospital. Of the 608 patients with AKI, 294 (48.4%), 185 (30.4%) and 129 (21.2%) had AKI stage 1, 2 and 3, respectively. Conclusion: Early resource planning is necessary when admitting COVID-19 patients. Nephrology should be consulted early, and measures should be in place to optimize outpatient follow-up in the nephrology clinic. Lastly, the use of nephrotoxic agents should be carefully considered and, if possible, avoided from the time of admission in patients with COVID-19.
RESUMO
A 59-year-old woman with a history of bilateral breast cancer, bilateral mastectomy, and bilateral latissimus dorsi flap reconstruction with tissue expanders, before expansion, developed spontaneous unilateral tissue expander migration on the side that had been irradiated. During the operation to return the migrated tissue expander to the chest, the expander was found at the back with a seroma. The chest pocket had collapsed, and a subcutaneous tunnel inferior to the flap inset was encountered, indicating the path of migration. To our knowledge, this is the first case reported of spontaneous tissue expander dislodgement to the donor site. This case is unique in that the patient had bilateral procedures but developed tissue expander migration only on the irradiated side. This highlights the need during pocket creation to account for the fibrosis caused by radiation that can create a constricted pocket promoting migration.
