Spinal epidural empyema.
Spinal epidural empyema is a very rare entity occurring with an estimated incidence of 1 per 10,000 hospital admissions. This condition has a reputation for presenting as a diagnostic challenge resulting in late diagnosis and delayed treatment. However, the cornerstones of treatment are prompt diagnosis and early treatment to prevent permanent paralysis and high mortality. We present a cluster of nine cases presenting to the neurosurgery unit over a 3-year period and discuss their relevant features in view of the most recent literature. The diagnosis of spinal epidural empyema was made with gadolinium-enhanced MRI in eight of nine cases. Staphylococcus aureus was isolated as the causative pathogen in all cases. All patients were treated with antibiotics. Eight patients had surgery for debridement and spinal decompression. One patient was treated successfully with antibiotics alone.

Anatomical basis for impotence following haemorrhoid sclerotherapy.
Impotence has been reported as a rare but important complication of sclerotherapy for haemorrhoids. The relationship between the anterior wall of the rectum and the periprostatic parasympathetic nerves responsible for penile erection was studied to investigate a potential anatomical explanation for this therapeutic complication. A tissue block containing the anal canal, rectum and prostate was removed from each of six male cadaveric subjects. The dimensions of the components of the rectal wall and the distance between the rectal lumen and parasympathetic nerves in the periprostatic plexus were measured in horizontal transverse histological sections of the tissue blocks at the level of the lower prostate gland (i.e. the correct level for sclerosant injection). The correct site of sclerosant in the submucosa was on average 0.6 mm (SD 0.3 mm) deep to the rectal mucosal surface and only 0.7 mm (SD 0.5 mm) in thickness. The nearest parasympathetic ganglion cells were a mean of only 8.1 mm (SD 2.0 mm) deep to the rectal lumen. The close proximity of the rectum to the periprostatic parasympathetic nerves defines an anatomical basis for impotence following sclerotherapy. This emphasises the need for all practitioners to be particularly careful when injecting in this area and for strict supervision of trainees.
