Steroid hormone hypersensitivity: clinical presentation and management.

Hypersensitivity to estrogens and progestogens is often undiagnosed. The condition has many manifestations, including premenstrual syndrome, dysmenorrhea, and impaired fertility. Diagnosis is confirmed by skin testing for inflammatory responses to small doses of the hormone, and desensitization with small doses of the hormone is the most appropriate form of management.

Measurement of electrical resistance of dermal-visceral zones as a diagnostic tool for gynecologic disorders.

BACKGROUND: Non-invasive screening tests may allow early diagnosis and prompt treatment, thereby potentially reducing morbidity and mortality and reducing costs for the community. This may be especially important for gynecologic pathologies that are difficult to promptly diagnose, such as endometriosis or ovarian cancer. OBJECTIVES: To evaluate the reliability of measuring skin resistance using the Medex Test for screening and diagnosis of gynecologic pathologies in a blinded single-center study. METHODS: We enrolled 150 patients: 59 with a functional disorder and 91 with an organic disease. Measurements were carried out in all patients and the results were analyzed separately by a second physician who was blinded to the patients' diagnosis. RESULTS: A high correlation was found between the clinical diagnosis and the results of the measurement of electrical skin resistance, with a specificity of 76.3% (45/59) for functional disorders and a sensitivity of 85.7% (78/91) for organic disorders, positive predictive value of 84.8% (78/92) and negative predictive value 77.6% (45/58). The kappa value for the results was 0.622, representing a value much better than expected randomly. CONCLUSIONS: The Medex Test has a good specificity and a high sensitivity for the diagnosis of gynecologic disorders. Further prospective studies are needed to validate these preliminary findings.

A prospective randomized controlled study of phototherapy using blue and blue-green light-emitting devices, and conventional halogen-quartz phototherapy.

OBJECTIVE: To determine the efficacy of blue versus blue-green phototherapy using new light sources with narrow luminous spectra. The devices made of high-intensity gallium nitride light-emitting diodes (LEDs) were also compared to conventional halogen-quartz bulbs phototherapy. DESIGN: Prospective open randomized study. PARTICIPANTS: A total of 114 jaundiced, but otherwise healthy term infants who met the entry criteria for phototherapy set by the American Academy of Pediatrics' Practice Parameter. MAIN OUTCOME MEASURES: The duration of phototherapy and the rate of decrease in total serum bilirubin (TSB). RESULTS: The mean TSB concentrations at initiation and termination of treatment, as well as the duration of phototherapy and the rate of decrease in TSB, were not statistically different in newborns receiving blue LED, blue-green LED or conventional phototherapy. The average rate of decrease in TSB (slope), after adjustment by a linear regression analysis for confounding factors, was -3.61 micromol/hour (95% confidence limits -5.47, -1.75) in the 25 newborns receiving blue LED phototherapy compared with -2.57 micromol/hour (-4.32, -0.82) in the 22 newborns treated with blue-green LED phototherapy and -3.42 micromol/hour (-5.02, -1.81) in the 57 newborns who received conventional phototherapy. CONCLUSIONS: When using low light irradiance, there was no statistically significant difference in the effectiveness of phototherapy using blue-green LEDs, blue LEDs or conventional halogen-quartz bulbs.
