Background: Autologous non-cultured cell (ANCC) spray has been used to treat burns, chronic wounds, and vitiligo, but its use in junctional epidermolysis bullosa (JEB) has not been published previously. Chronic wounds in JEB are caused by mutations of laminin 332 (L322), whose function is to attach and act as a glue in the basal membrane. It is proposed that ANCC applications can provide keratinocytes and fibroblasts required to improve epithelization and spontaneously correct revertant keratinocytes in the wound area.
Purpose: To develop a modified procedure of ANCC spray and improve epithelization using silver sulfadiazine covered with plastic wrap to treat chronic wounds of JEB.
Patients And Methods: Shave excision of the donor site was performed on a 19-year-old girl with JEB. The ANCC spray was prepared and applied to the chronic wound, which was then covered with silver sulfadiazine occluded with plastic wrap.
Results: Following the ANCC spray application, epithelization was successfully initiated. Unfortunately, the wounds recurred after four months of follow-up.
Conclusion: The modified application method of ANCC spray provides a good alternative to treat chronic wounds in JEB.

Background: Take-home naloxone (THN) kits have been designed to provide community members (including people who use drugs, their families and/or significant others) with the necessary resources to address out-of-hospital opioid overdose events. Kits typically include two doses of naloxone. This 'twin-pack' format means that lay responders need information on how to use each dose.

Article Synopsis
- Take-home naloxone (THN) is an effective and affordable method to reduce opioid overdose deaths, but its use can lead to negative side effects like withdrawal symptoms and anger in those revived.* -
- The study involved a combination of a controlled trial on naloxone education for opioid users and interviews with participants who experienced overdose rescues in NYC between 2014-2019, analyzing various factors affecting the adverse outcomes.* -
- Results showed that negative interactions during resuscitation, such as criticism, significantly increased the likelihood of anger in overdose survivors, while positive communication greatly reduced it, indicating that how rescuers communicate plays a crucial role in emotional responses post-rescue.*

Article Synopsis
- * A qualitative study involving interviews with 46 opioid users, conducted during a 5-year trial in NYC, explored their experiences of naloxone administration during overdose reversals, focusing on adverse effects from their perspectives.
- * The research identified three main outcomes post-naloxone administration: intense anger or aggression ("rage"), withdrawal symptoms, and a neutral state ("not rage, not withdrawal"), highlighting the complex reactions that may follow overdose reversal.

Background And Aims: Providing take-home naloxone (THN) to people who use opioids is an increasingly common strategy for reversing opioid overdose. However, implementation is hindered by doubts regarding the ability of people who use opioids to administer naloxone and respond appropriately to overdoses. We aimed to increase understanding of the competencies required and demonstrated by opioid users who had recently participated in a THN programme and were subsequently confronted with an overdose emergency.
