AI Article Synopsis
- Penile intraepithelial neoplasia (PeIN) is a rare condition that can lead to invasive penile cancer, and a systematic review was conducted to evaluate treatment options.
- Topical treatments like imiquimod and 5-fluorouracil showed varying response and recurrence rates, with some side effects leading to a 12% discontinuation rate.
- Surgical options, including circumcision and different excision techniques, had different recurrence rates, underscoring the need for careful monitoring and personalized treatment plans since PeIN can recur or progress.
Article Abstract
Penile intraepithelial neoplasia (PeIN) is a rare skin condition with potential to progress to invasive penile cancer. We performed a systematic review of treatment options and outcomes for PeIN. Topical agents showed response and recurrence rates of 40-100% and 20% for imiquimod, and 48-74% and 11% for 5-fluorouracil, respectively. Discontinuation of topical agents because of side effects was observed in 12% of cases. Response rates for laser therapies were 52-100%, with recurrence in 7-48% of cases and a change in penile sensitivity in 50%. Circumcision cleared preputial PeIN. Rates of recurrence after surgical treatment of glans PeIN were 25% for wide local excision, 4% for Mohs surgery, 5% for total glans resurfacing, and 10% for glansectomy. There are limited data on factors predictive of treatment response and on sequencing of treatment options. PATIENT SUMMARY: Several treatment options are available for men with precancerous lesions of the foreskin or glans. Close follow-up is necessary as lesions can recur or progress to invasive penile cancer.

Antibody-mediated rejection (AMR) remains a major complication after solid organ transplantation (SOT). Current treatment options are inefficient and result in drastic impairment of the general immunity. To selectively eliminate responsible alloreactive B cells characterized by anti-donor-HLA B-cell receptors (BCRs), we generated T cells overcoming rejection by antibodies (CORA-Ts) engineered with a novel chimeric receptor comprising a truncated donor-HLA molecule as antigen recognition domain.

Post-dural puncture headache (PDPH) is a debilitating complication of neuraxial anesthesia, particularly prevalent in obstetric patients, usually characterized by a postural headache. PDPH is hypothesized to result from cerebrospinal fluid leakage through a dural puncture, triggering symptoms like neck stiffness and subjective hearing changes. While conservative measures are common for treatment, more refractory cases may require invasive interventions such as an epidural blood patch (EBP).

Objectives: This systematic review is aimed to evaluate the efficacy and safety of robotic Cyberknife radiotherapy (CKRT) in the treatment of uveal melanoma (UM).
Methods: Clinical studies published in English that assessed the efficacy and safety of robotic CKRT in UM were systematically searched in PubMed, Web of Science, Cochrane and Embase from inception to July 2023. Studies reporting extraocular tumours or other radiosurgery approaches were excluded.

Objective: To investigate the predictive ability of the MRI-based vertebral bone quality (VBQ) score for pedicle screw loosening following instrumented transforaminal lumbar interbody fusion (TLIF).
Methods: Data from patients who have received one or two-level instrumented TLIF from February 2014 to March 2015 were retrospectively collected. Pedicle screw loosening was diagnosed when the radiolucent zone around the screw exceeded 1 mm in plain radiographs.
