The effect of estradiol valerate and allylestrenol on endometrial transformation in hypergonadotropic hypogonadic women

The effect of estradiol valerate and allylestrenol on the endometrial transformation of five hypergonadotropic hypogonadic women was evaluated. Estradiol valerate was administered throughout the whole induced cycle (28 days), while allylestrenol was added during the second half of the cycle. Endometrial biopsies were performed during allylestrenol treatment and were evaluated histologically. Samples of endometrium were also subjected to one-dimensional SDS electrophoresis. Of ten biopsies performed, only one was interpreted to be in-phase, while the others were dated proliferative (4 biopsies) or showed abortive or out-of-phase secretory transformation. The highest mean serum progesterone level, detected under allylestrenol treatment, was 1.5 ng/ml. Protein electrophoresis demonstrated relative sequential changes in the protein patterns of the 115 kDa and 150 kDa protein bands. It is concluded that allylestrenol, although having gestagen properties, may not be efficient for the induction of an adequate secretory transformation of human endometrium in the absence of ovaries.     

Applying item response theory to enhance health outcomes assessment

Background Health-related quality of life (HRQL) is an accepted outcome measure in patients with mood and anxiety disorders. Yet, surprisingly little attention has been paid to the determinants. In this paper we test the hypothesis that it is associated with personality traits while controlling for mental disorders. Methods A large sample of outpatients (n=640) with mood and anxiety disorders was studied. The empirically supported five factor model of normal personality traits was assessed using the NEO-FFI and includes: neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness. Mental disorders were assessed with the CIDI, and HRQL with the SF-36. Results Regression analyses revealed that the NEO-FFI scores, with the exception of conscientiousness, were significantly associated with SF-36 subscales and summary scores, independently from the mental disorders. The percentage of explained variance due to the personality traits was highest for the subscales Vitality (10.0%), Mental Health (13.3%) and the Mental Health Summary Score (9.5%). Furthermore, specific personality traits were related to specific SF-36 subscales. Conclusions A low HRQL of patients with mood or anxiety disorders is not only determined by the disease or the current health but is also shaped by personality traits that are relatively stable throughout an individual's life time.     

Feasibility of near real-time image-guided sinus surgery using intraoperative fluoroscopic computed axial tomography.

OBJECTIVE: One of the main limitations of image-guided surgery is that navigation relies on the use of a CT scan obtained before surgery and is unable to be updated during the procedure. A software addition has been developed to allow reconstruction of CT-like images from a series of fluoroscopic scans and integrate these into an image-guided system (GE Healthcare Surgical Navigation, Lawrence, MA). We report our initial experience with a series of patients undergoing intraoperative fluoroscopic navigation in sinus surgery. STUDY DESIGN AND SETTINGS: After institutional review board clearance, we prospectively studied 14 consecutive patients undergoing image-guided sinus surgery with the use of intraoperative fluoroscopy. RESULTS: All patients had preoperative and postoperative fluoroscopic images reconstructed into CT-like images. By the conclusion of the study, images were adequate in quality and accurate navigation was achieved. CONCLUSION: Real-time image-guided sinus surgery using fluoroscopy is feasible. Future studies will need to focus on defining the procedures that could benefit, such as tumor resection, to enhance patient safety during these operations.     

Diabetes in sex offenders

Thirteen diabetic male sex offenders were compared to 13 nondiabetic sex offenders matched on age, education and offense type. A standard battery of tests administered in the assessment of sex offenders was used to compare the two groups. The tests examine sexual history and preference, substance abuse, violence, personality, and neuropsychological impairment. Results showed that diabetics more often than controls complained of impotence and were nonresponders during phallometric testing. Diabetics, as adults, tended to have less sexual experience with adults and more with pubescent females. The two groups did not differ in number of sexual or nonsexual offenses. The diabetics reported more problems controlling their emotions and more often than controls presented in assessment with inappropriate and/or aggressive behavior and poor cooperation. MMPI results showed diabetics to have more overall clinical disturbance than controls including anxiety, health concerns, family problems, authority problems, criminality, confused thinking and ruminating. Diabetics and controls did not differ in reported frequency of violent behavior but the diabetics responded more extremely, given the circumstances. Diabetics tended to show more violence to their own children. The role of diabetes in the relapse cycle model of offending is discussed.
