Atraumatic bilateral osteonecrosis of the femoral head (ONFH) is a rare phenomenon whose etiology is not fully understood. In this report, we describe the case of a 75-year-old female patient who developed rapidly onset bilateral ONFH after intra-articular corticosteroid injections. She was treated with staged bilateral total hip arthroplasty.

Aberrant expression of glucose-dependent insulinotropic peptide receptors (GIPR) might regulate increased steroidogenesis in patients with ACTH-independent cortisol hypersecretion. This study investigated the presence of aberrant GIPR expression in patients with ACTH-independent cortisol hypersecretion and bilateral adrenal adenomas.Patients with bilateral adrenal adenomas, ACTH-independent CS and aberrant GIPR screened via mixed meal test were included.

The low dose dexamethasone stimulation test (LDDST) is routinely used in canine medicine but in the few cases in guinea pigs diagnosed with hypercortisolism, the adrenocorticotropic hormone (ACTH) stimulation test was used. The objective of the authors was to conduct a pilot study and find out if the standard test used in dogs can be used in this species.A 4-year-old intact female hairless guinea pig showed bilaterally enlarged adrenal glands and high cortisol levels.

Objectives: To clarify the role of hippocampal glutamate system in regulating HPA axis in mediating the effect of electroacupuncture (EA) at the heart meridian for improving myocardial injury in rats with acute myocardial ischemia (AMI).
Methods: Male SD rats were randomized into sham-operated group, AMI group, EA group, and L-glutamic acid+EA group (=9). Rat models of AMI were established by left descending coronary artery ligation, and EA was applied at the "Shenmen-Tongli" segment; the rats in L-glutamic acid+EA group were subjected to microinjection of L-glutamic acid into the bilateral hippocampus prior to AMI modeling and EA treatment.

Both the autonomic nervous system and the hypothalamic-pituitary-adrenal axis respond to systemic immune challenge by initiating anti-inflammatory reflexes. Here we compare those two homeostatic responses in vivo. We first confirmed in male urethane-anaesthetized rats that disabling the autonomic reflex by bilateral section of the splanchnic sympathetic nerves increased plasma tumor necrosis factor α (TNF) responses to systemic lipopolysaccharide (LPS, 60 µg/kg i.
