A super-resolution proof of concept in a cycloidal coded aperture miniature mass spectrometer.

Rationale: Higher resolution in fieldable mass spectrometers (MS) is desirable in space flight applications to enable resolving isobaric interferences at m/z < 60 u. Resolution in portable cycloidal MS coupled with array detectors could be improved by reducing the slit width and/or by reducing the width of the detector pixels. However, these solutions are expensive and can result in reduced sensitivity.

Abdominal wall necrotising fasciitis due to dislodged percutaneous endoscopic gastrostomy tube.

Accessing the stomach via a percutaneous endoscopic gastrostomy (PEG) tube is the preferred (and sometimes the only) method for providing enteral nutritional support in disabled patients. However, it is associated with serious and potentially lethal complications which must be completely recognised by physicians, by nurses and especially by radiologists. Abdominal wall necrotising fasciitis of a dislodged or leaking PEG tube could be a lethal complication.
