A 55-year-old woman presented with rapidly progressive brainstem dysfunction which led to death within a month. She also had constipation for three weeks, and barium enema showed ileus. Subacute encephalomyelitis predominantly involving the medulla and pons correlated with the patient's initial symptoms. In addition, ganglionitis of the myenteric plexuses explained the constipation and ileus. Ganglioradiculoneuropathy was another finding. The presence of abundant neuronophagia in the brainstem, dorsal root ganglia, and myenteric plexuses raised the speculation that a putative virus, toxic agent, or immune reaction possessed special affinity for neurons and ganglion cells. The neuropathological findings were similar to paraneoplastic changes, but no neoplasm was found.

We report the association of neurological and intestinal disorders with the reactivation of Epstein-Barr virus (EBV) in a child. This previously healthy 13-yr-old boy presented with pharyngitis and acute abdominal ileus. Laparotomy excluded a mechanical obstruction. Postoperatively, he suffered from prolonged intestinal obstruction, pandysautonomia, and encephalomyelitis. Histological examination of the appendix and a rectal biopsy taken 3 months after the onset showed an absence of ganglion cells (appendix) and hypoganglionosis (rectum), with a mononucleate inflammatory infiltrate in close contact with the myenteric neural plexuses. EBV-PCR was positive in the blood and cerebrospinal fluid, and in situ hybridization with the Epstein-Barr virus encoded RNA probe showed positive cells throughout the appendix wall including the myenteric area, in a mesenteric lymph node, and in the gastric biopsies. EBV spontaneous lymphocytic proliferation was noted in the blood. The serology for EBV showed previous infection but anti-early antigen antibodies were present. No immunodeficiency was found. Neurological and GI recovery occurred after 6 months of parenteral nutrition and bethanechol. The omnipresence of EBV associated with the neurointestinal symptoms suggest that the virus was the causal agent. This is the first documented case of acquired hypoganglionnosis due to EBV reactivation.

We report the case of a 57 year old woman with typical clinical features of the stiff man syndrome (SMS) and antibodies to glutamic acid decarboxylase (antiGADAb), who developed a supranuclear gaze palsy, ileus and died of bronchopneumonia eight years after the onset of illness. Post mortem examination revealed perivascular lymphocyte cuffing throughout the cerebral hemispheres, brainstem and spinal cord and neuronal loss in medial anterior horns of the cervical spinal cord. These findings support the notion that the SMS and progressive encephalomyelitis with rigidity (PER) form a clinical and pathologic continuum.

We report the outcome of a 30-month programme to rederive 310 specific pathogen-free mouse strains to populate a new individually ventilated cage barrier facility at the Mary Lyon Centre (MLC), Medical Research Council (MRC) Harwell. The mice were rederived in a self-contained quarantine suite and embryo-recipient females were health-screened to assess microbiological status, before moving their offspring into the new facility. The MLC currently houses approximately 49,000 mice in about 9750 cages and we have 30 months of follow-up health screen data. Embryo rederivation and hysterectomy have high safety margins; however, the precaution of performing the programme in isolators facilitated the containment and decontamination of two mouse hepatitis virus (MHV) infection outbreaks. Rederivation of the colony has eliminated endemic MHV, mouse adenovirus type 2 (MAV-2), Theiler's murine encephalomyelitis virus, pinworms, intestinal protozoa, Pasteurella pneumotropica, Helicobacter spp. and mites. The improvements in microbiological status have had notable benefits for mouse health and welfare and the science at MRC Harwell. Previously important clinical entities such as sudden death associated with lactation ileus in C3H/HeH mice, early weight loss associated with inflammatory bowel disease in B6-TgN(HDexon1)61Gpb and B6TgN-(HD82Gln)81Dbo (Huntington) mice and early weight loss in male mice mutagenized with N-ethyl-N-nitrosourea have been markedly reduced or eliminated.
