Background: Vitiligo is a disorder of dyspigmentation that can impact quality of life. While narrow-band ultraviolet B (NBUVB) is an effective treatment for vitiligo, a subset of patients are unable to respond to phototherapy as they cannot photoadapt. However, nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to increase the minimal erythema dose.
Purpose: To determine whether ibuprofen allows non-photoadapters to respond to therapeutic doses of NBUVB and maintain photoadaptation.
Method: Four patients unable to tolerate NBUVB or excimer past a dose of 1000 mJ/cm were enrolled in the study and given ibuprofen 400 mg prior to phototherapy, which was performed 2-3 times a week. Patients were followed up to 72 treatments to demonstrate photoadaptation and maintenance of response to phototherapy. Patients were clinically monitored by serial photographs approximately every 12 treatments. Response to phototherapy was monitored by tracking the dose of NBUVB received at each session. Maintenance of response was monitored for six treatments after discontinuing the ibuprofen. Percent change in pigmentation was also recorded.
Results: Three out of four subjects enrolled in the study were able to increase their doses of phototherapy to a therapeutic range, and subjects continued to photoadapt for six treatments after discontinuing ibuprofen. Two subjects achieved repigmentation during their course of phototherapy.
Conclusion: Ibuprofen may be a safe alternative to corticosteroids for select patients with vitiligo that are unable to photoadapt. It appears that the ability to photoadapt continues once ibuprofen is discontinued, negating the need for chronic use. Enabling photoadaptation allows patients to achieve therapeutic doses of NBUVB phototherapy, leading to repigmentation and improved outcomes.
Trial Registration: The trial was registered through Henry Ford Hospital IRB-No. 9744.

Background: Vancomycin, an antibiotic with activity against methicillin-resistant Staphylococcus aureus (MRSA), is frequently included in empiric treatment for community-acquired pneumonia (CAP) despite the fact that MRSA is rarely implicated in CAP. Conducting polymerase chain reaction (PCR) testing on nasal swabs to identify the presence of MRSA colonization has been proposed as an antimicrobial stewardship intervention to reduce the use of vancomycin. Observational studies have shown reductions in vancomycin use after implementation of MRSA colonization testing, and this approach has been adopted by CAP guidelines.

The diagnostic and prognostic value of quantitative electroencephalogram (qEEG) in the the onset of postoperative delirium (POD) remains an area of inquiry. We aim to determine whether qEEG could assist in the diagnosis of early POD in cardiac surgery patients. We prospectively studied a cohort of cardiac surgery patients undergoing qEEG for evaluation of altered mental status.

The COVID-19 pandemic has triggered the adoption of new technologies to reduce the need for in-person physical therapy (PT). This study evaluated the impact of the COVID-19 pandemic on PT utilization and outcomes of patients prescribed a smartphone-based care management platform (sbCMP) for self-directed rehabilitation (SDR). A secondary analysis of data collected in a multicenter, prospective cohort trial investigating a mobile platform to deliver SDR after arthroplasty was performed.

Immune checkpoint inhibitors (ICIs) have dramatically improved the prognosis of patients with cancers. However, ICIs can provoke systemic toxicities, which are known as immune-related adverse events (irAEs). Polymyalgia rheumatica (PMR)-like syndrome induced by ICI is one of the most common rheumatic irAEs.

Background: Breast milk has significant benefits for preterm babies, but 'very preterm' babies are unable to feed directly from the breast at birth. Their mothers have to initiate and sustain lactation through expressing milk for tube feeding until their babies are developmentally ready to feed orally. There are wide disparities between neonatal units in England in rates of breast milk feeding at discharge.
