Ninety-five women undergoing induced abortion were randomly premedicated with oral diazepam, 5 or 10 mg, midazolam 15 mg, or intramuscular placebo, 40-60 min before the induction of anesthesia. Prior to premedication and again prior to the procedure, the women completed the questionnaire sheet for the Profile of Mood States (POMS), and plasma samples for immunoreactive beta-endorphin (ir beta-E) and ACTH were taken. The Oblique Tension-Anxiety (T-A) Factor scores derived from POMS correlated with plasma concentrations of ir beta-E and ACTH after premedication. The T-A scores decreased in women premedicated with diazepam, 5 and 10 mg, or midazolam, 15 mg, but not in women treated with placebo. The women premedicated with midazolam, 15 mg, became more fatigued after premedication. The changes in blood pressure after premedication correlated with T-A scores. A positive correlation was found between heart rate and plasma beta-endorphin concentration. The changes in ir beta-E and ACTH did not correlate with the changes in T-A scores. We conclude that POMS T-A scores are useful for assessment of preoperative anxiety and the effect of premedication. The present study did not provide any reliable proof to confirm the hypothesis of a relationship between plasma concentrations of ir beta-E or ACTH and preoperative anxiety. Since many factors modulate endorphin and ACTH secretion prior to operation, the measurement of endogenous opiates may be of limited value in assessment of the effects of preanesthetic medication.

Pheochromocytoma (PHEO) occasionally associates with pathological lesions of the adrenal cortex. In most of them, ectopic adrenocorticotropic hormone (ACTH) produced by PHEO resulted in bilateral adrenocortical hyperplasia. The coexistence of PHEO and pre-clinical Cushing's syndrome (PCS) of the same adrenal gland has rarely been reported. We report on a patient and discuss the peculiar diagnostic aspects of this entity. A 52-yr-old Turkish woman was hospitalized at Farabi Hospital for further examinations of a right adrenal mass that was incidentally discovered by abdominal ultrasonography during examinations for abdominal bloating and "gas" in other hospital. The patient had a history of palpitations, nervousness, sweating and heat intolerance. On admission, her blood pressure was 140/90 mmHg. A physical examination revealed no signs of an excessive production of adrenocortical steroids such as in CS. Tension Holter monitoring revealed paroximal hypertension attacks (183/105 mmHg). Urinary catecholamines were markedly increased. Her serum cortisol concentrations ranged from 5 to 17 microg/dl, whereas ACTH levels were undetectable. Cortisol was not suppressed on the overnight 1 mg oral dexamethasone suppression test (DST), 2-day low-dose dexamethasone suppression test (DST). Abdominal computed tomography and magnetic resonance imaging studies revealed a solid round tumor approximately 4 cm in diameter, located in the right adrenal gland. A 131 lodine-metaiodobenzylguanidine (131 I-MIBG) scan revealed uptake within tumor in the right adrenal gland. Right adrenalectomy was performed; the surgical specimen revealed PHEO and adrenocortical hyperplasia. To our knowledge, the present report is a rare case of PHEO combined with PCS in the same adrenal gland.

Cranial electrotherapy stimulation (CES) is reported to aid in relieving symptoms of depression and anxiety, though the mechanism underlying this effect remains unclear. Therefore, the present study aimed to evaluate changes in the hypothalamic-pituitary-adrenal (HPA) axis response and levels of neurotrophic factors, as well as changes in mood state, in patients undergoing CES therapy. Fifty healthy postmenopausal women were randomly assigned to either a Sham CES group (n = 25) or an Active CES group (n = 25). CES treatment was conducted in 20-minute sessions, three times per week for 8 weeks, using a micro current cranial electrotherapy stimulator. Blood samples were collected prior to and following the 8-week treatment period for measurement of cortisol, adrenocorticotropic hormone (ACTH), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) levels. Changes in mood state were also examined at the time of blood collection using the Profile of Mood States (POMS). No significant differences in cortisol, ACTH, BDNF, or NGF were observed between the two participant groups (p > 0.05) following the treatment period. However, those in the Active CES group exhibited significantly decreased Tension-Anxiety and Depression-Dejection scores on the POMS relative to pre-treatment scores (p < 0.05). Furthermore, Depression-Dejection scores following treatment were significantly lower in the Active CES group than in the Sham CES group (p < 0.05). No significant differences were observed in any other POMS scores such as Anger-Hostility, Vigor-Activity, Fatigue-Inertia, and Confusion-Bewilderment (p > 0.05). These results suggest that 8 weeks of CES treatment does not induce changes in blood levels of neurotrophic factors or HPA-axis-related hormones, though such treatment may be effective in treating symptoms of anxiety and depression.
