BACKGROUND: Cushing's syndrome is a state of hypercortisolism manifesting non-specific clinical; features where its diagnosis entails biochemical confirmation of cortisol excess. this study aims to validate the efficacy of midnight salivary cortisol as a screening test for Filipino suspected with Cushing's syndrome and determine the cut-off value applicable in the local setting.

METHODS: This is a cross-sectional study of Filipinos suspected with endogenous Cushing's syndrome seen at a tertiary hospital. Modification of plasma cortisol measured by RIA was used to measure salivary cortisol. The sensitivity, specificity, positive predictive curve, negative predictive curve and area under the screening tests were estimated and compared using 48 hour low dose dexamethasone suppression test (LDDST) as the reference standard.

RESULTS: The determine cut-off value (? 7.0 nmol/L) for salivary cortisol showed a relatively high sensitivity (91.3%) and specificity (89.5%) in detecting cases suspected of Cushing's syndrome. One milligram (1mg) dexamethasone suppression test had the highest sensitivity (100%) but had the lowest specificity (68.4%) as a screening test. The area under the curve of the three diagnostic test appeared to be similar when compared with the low dose dexamethasone suppression test.

CONCLUSIONS: Using a cut-off value of 7nmol/L, local utility if late-night salivary cortisol has a high sensitivity and specificity in detecting Cushing's syndrome. It has a similar efficiency with 24-hour urine free cortisol and 1mg dexamethasone suppression test as a screening test for Cushing's syndrome. Salivary cortisol may be considered as a valid initial screening test for Filipinos suspected of cushing's syndrome.

To investigate the intervention effects of Morinda officinalis How. on 'Kidney-yang deficiency syndrome' induced by hydrocortisone in rats, the metabolic profiles of rat urine were characterized using proton nuclear magnetic resonance and principal component analysis (PCA) was applied to study the trajectory of urinary metabolic phenotype of rats with 'Kidney-yang deficiency syndrome' under administration of M. officinalis at different time points. Meanwhile, the intervention effects of M. officinalis on urinary metabolic potential biomarkers associated with 'Kidney-yang deficiency syndrome' were also discussed. The experimental results showed that in accordance to the increased time of administration, an obvious tendency was observed that clustering of the treatment group moved gradually closed to that of the control group. Eight potential biomarkers including citrate, succinate, alpha-ketoglutarate, lactate, betaine, sarcosine, alanine and taurine were definitely up- or down-regulated. In conclusion, the effectiveness of M. oficinalis on 'Kidney-yang deficiency syndrome' is proved using the established metabonomic method and the regulated metabolic pathways involve energy metabolism, transmethylation and transportation of amine. Meanwhile, the administration of M. officinalis can alleviate the kidney impairment induced by 'Kidney-yang deficiency syndrome'.

BACKGROUND: The efficacy of oral corticosteroids in the treatment of chronic asthma is undisputed, but their long-term use is associated with adverse side-effects, including supression of the hypothalamic-pituitary adrenal axis function, osteoporosis, weight gain, hypertension and impaired glucose tolerance. The introduction of inhaled corticosteroids in the early 1970's represented a significant therapeutic advance in the management of asthma, since these compounds combined high topical potency with low systemic activity. Fluticasone propionate is a new topically active synthetic glucocorticosteroid that combinds a high degree of efficacy with negligible systemic bioavailability. This study was perfomed to determine the effect of inhaled fluticasone propionate on the adreocortical supression in patients with bronchial asthma or chronic obstructive pulmonary disease. METHODS: The adrenocortical function was assessed by measurement of plasma cortisol concentration at 8 o'clock in morning and free cortisol in 24 hour urine collection at intervaL Absolutely, no steroid was taken during pretreatment period of l0days. There after each subject inhaled fluticasone aerosol, in daily doses of 500 or l000 mierograms for l2days. The dose was delivered by metered dose inhaler(MDI). RESULTS: The serum cortisol and 24hour urinary free cortisol were not decreased during the treatment period in patients with inhaled fluticasone propionate in daily doses of 500 micrograms. In contrast, serum cortisol was significantly decreased on 9th and 12th day(p less than 0.05). And, 24hour urinary free cortisol was also significantly decreased on 3rd and 12th day of treatement period(p less than 0.05) in patients with inhaled fluticasone in daily doses of 1000 micrograms. CONCLUSION: These results suggested that endogenous cortisol secretion was not supressed after short-term inhalation of fluticasone in daily dose of 500 micrograms, but in daily dose of 1000 micrograms, the endogenous cortisol secretion was supressed.

BACKGROUND: Topical inhaled steroids, budesonide(Bu) and beclomethasone dipropionate (BDP), are now established as effective drugs in the management of chronic asthma. These drugs have high topical anti-inflammatory effect with low systemic activity. This study was performed to determine the effects of two inhaled corticosteroids, Bu and BDP, on the adrenocortical supression in 44 patients with bronchial asthma or chronic obstructive pulmonary disease. METHODS: The adrenocortical function was assessed by measurement of serum cortisol concentration at 8 o'clock in morning and free cortisol in 24-hour urine collection at interval in 44 patients. No steroid was administered during the pretreatment period of 10 days and the final 6 days of the study. Each subject inhaled BDP or Bu, in daily doses of 800 or 1,600 micrograms for 12 days. The dose was delivered by metered dose inhaler (MDI) or diskhaler or large spacing device attached to MDI. RESULTS: The levels of serum cortisol and 24-hour urinary free cortisol were decreased during the treatment period in patients inhaled Bu delivered by MDI in daily doses of 800 and 1,600 micrograms. In contrast, serum cortisol level was decreased on 6 and 12th day of treatment period in patients with BDP diskhaler in daily doses of 800 micrograms. In daily doses of 1,600 micrograms, the serum cortisol and 24hour urine free cortisol levels were decreased on 6, 9 and 12th day of treatment period in patients with BDP disk haler. The serum cortisol and 24-hour urinary free cortisol levels were not significantly decreased during the treatment period in patients inhaled Bu delivered by large spacing device attached to a MDI. CONCLUSION: These results showed that 1) the endogenous cortisol secretion was suppressed after inhalation of BDP and Bu in daily doses of 800 and l,600micrograms, 2) Bu with MDI suppressed the adrenocortical function more than BDP with diskhaler, in daily doses of 1600 micrograms, and 3)large spacing device attached to a MDI might decrease the risk of suppression in the hypothalamic -pituitary- adrenal axis.

PURPOSE: The purpose of this study was to evaluate the effects of self-foot reflexology on stress (perceived stress, urine cortisol level, and serum cortisol level), fatigue, skin temperature and immune response in female undergraduate students. METHODS: The research design was a nonequivalent control group pretest-post test design. Participants were 60 university students: 30 in the experiment group and 30 in the control group. The period of this study was from April to June 2010. The program was performed for 1 hr a session, three times a week for 6 weeks. The data were analyzed using the SPSS/WIN 17.0 program. RESULTS: The results showed that self-foot reflexology was effective in reducing perceived stress and fatigue, and raised skin temperature in female undergraduate students. But cortisol levels and immune response were not statistically significant different. CONCLUSION: The results of this study indicate that self-foot reflexology is an effective nursing intervention in reducing perceived stress and fatigue and, in improving skin temperature. Therefore, it is recommended that this be used in clinical practice as an effective nursing intervention for in female undergraduate students.

We describe here the case of a 39-year-old woman with a cortisol-producing adrenal adenoma and she presented with endometrial hyperplasia and hypertension without the specific characteristics of Cushing's syndrome. The patient had consulted a gynecologist for menometrorrhagia 2 years prior to her referral and she was diagnosed with endometrial hyperplasia and hypertension. Her blood pressure and the endometrial lesion were refractory despite taking multiple antihypertensives and repetitive dilation and curettage and progestin treatment. On admission, the clinical examination revealed mild central obesity (a body mass index of 22.9 kg/m2, a waist circumference of 85 cm and a hip circumference of 94cm), but there was no hirsutism and myopathy. She showed impaired glucose tolerance on an oral glucose tolerance test. The biochemical hypercortisolemia together with the prolactin and androgen levels were evaluated to explore the cause of her anovulation. Adrenal Cushing's syndrome was confirmed on the basis of the elevated urinary free cortisol (454 microgram/24h, normal range: 20-70) with a suppressed ACTH level (2.0 pg/mL, normal range: 6.0-76.0) and the loss of circadian cortisol secretion. A CT scan revealed a 3.1 cm, hyperechoic, well-marginated mass in the left adrenal gland. Ten months post-adrenalectomy, the patient had unintentionally lost 9 kg of body weight, had regained a regular menstrual cycle and had normal thickness of her endometrium.

The most common endogenous cause of Cushing's syndrome is Cushing's disease. The evaluation of patients with suspected Cushing's disease and syndrome requires an understanding of the proper use and limitations of the tests commonly included in the diagnostic work-up. The best screening test for Cushing's syndrome is a 24-hour urine collection with analysis for urinary free cortisol excretion. Low-dose and high-dose dexamethasone suppression tests, corticotropin assays, a corticotropin-release hormone stimulation test and inferior petrosal sinus cathaterization may be required for a definitive diagnosis. MRI is useful in localizing the lesion but some limitations. Surgical removal of the lesion by a trans-sphenoidal appraoch is usually successful, but long-term follow-up is required. We report a case of Cushing disease which shows such typical clinical characteristics of Cushing syndrome as weight gain, skin lesions, truncal obesity, striae, hypertension.
