Penile hair tourniquet to base of penis resulting in circumferential separation of shaft skin without vascular compromise: An unusual case report.

Hair tourniquet syndrome occurs when a strand of hair or thread becomes wrapped around an appendage, causing injury which can progress to ischemia, necrosis or autoamputation. A 2 year old uncircumcised male presented with 1 day of erythema to base of penis followed by a bleeding wound of 5 hours duration. On examination, there was circumferential separation of shaft skin at the base of the penis.

Germinal center reactions in tertiary lymphoid structures associate with neoantigen burden, humoral immunity and long-term survivorship in pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDAC) has traditionally been thought of as an immunologically quiescent tumor type presumably because of a relatively low tumor mutational burden (TMB) and poor responses to checkpoint blockade therapy. However, many PDAC tumors exhibit T cell inflamed phenotypes. The presence of tertiary lymphoid structures (TLS) has recently been shown to be predictive of checkpoint blockade response in melanomas and sarcomas, and are prognostic for survival in PDAC.

Implementation and Validation of an Automated Flow Cytometry Analysis Pipeline for Human Immune Profiling.

Automated reagent preparation, sample processing, and data acquisition have increased the rate at which flow cytometry data can be generated. Furthermore, advances in technology and flow cytometry instrumentation continually increase the complexity and dimensionality of this data. Together, this leads to increased pressure on manual data analysis, which has inherent limitations including subjectivity of the analyst and the length of time needed for data processing.

Autophagosome-based strategy to monitor apparent tumor-specific CD8 T cells in patients with prostate cancer.

The immune system plays an essential role in eradicating cancer in concert with various treatment modalities. In the absence of autologous tumor material, no standardized method exists to assess T cell responses against the many antigens that may serve as cancer rejection antigens. Thus, development of methods to screen for therapy-induced anti-tumor responses is a high priority that could help tailor therapy.
