Listeria rhombencephalitis (LRE) is a rare encephalitis of the hindbrain that can present with a variety of neurological symptoms. It is a diagnostic challenge, but prompt antimicrobial therapy is important to prevent high rates of mortality and morbidity. We report two cases of LRE, with several contrasting clinical features and different disease courses. Despite being rare, it is important to consider listeria in patients with possible meningoencephalitis, even if cultures are negative. Empirical treatment of meningoencephalitis should provide coverage for listeria, especially if the patient is at risk of listeriosis or there is a potential history of listeria exposure.

Compared with control subjects, the elderly female patients with hypothalamic-pituitary disease and GHD had a significantly higher total fat mass, with the WHR indicating a more central fat distribution and lower female serum IGF-1 levels. In contrast, elderly male patients had similar total fat mass, WHR and IGF-1 levels compared to the controls. There were no significant differences in the lipid profiles between male or female patients compared to controls. However, many of the male patients were receiving androgen replacement which might have influenced these results. Low HDL cholesterol concentrations are probably a better predictor of future cardiovascular disease than raised LDL cholesterol levels in the elderly population and these were similar in patients and controls for both

Intraocular pressures during the day are influenced by the morning hydrocortisone replacement dosage with significantly higher intraocular pressure levels in the early afternoon following 20 mg compared with 10 mg. A morning hydrocortisone dose of 10 mg leads to a more physiological intraocular pressure profile during the day. These data support the view that a daily replacement dose of 30 mg hydrocortisone may be excessive.

These patients with untreated GHD did not have deterioration of body composition or lipid profiles when reassessed after a period of 2 years. In fact, fat mass fell. The control subjects did have a significant decrease in total cholesterol but no change in other lipids or body composition. Some quality of life domains did deteriorate in the patients with GHD. However, the control subjects also had worse quality of life scores after 2 years which were then little different from the GHD patients. These results raise doubts about the benefits of GH replacement in elderly people with GHD.
