The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many

admission. This proportion could already be greater in some parts of the country and may increase if referrals of cases of self-poisoning increase faster than the facilities for their assessment and management. The provision of social work and psychiatric expertise in casualty departments may be one means of preventing unnecessary medical admissions without risk to the patients. Dr Blake's and Dr Bramble's figures do not demonstrate, however, that any advantage would attach to medical teams taking over assessment from psychiatrists except that, by implication, assessments would be completed sooner by staff working on the ward full time. What the figures actually suggest is that if assessment of overdoses were left to house doctors there would be an increase in admissions to psychiatric units (by 19°U), outpatients (by 5O°'), and referrals to social services (by 140o). So for house doctors to assess overdoses would provide no economy for the psychiatric or social services. The study does not tell us what the consequences would have been for the six patients who the psychiatrists would have admitted but to whom the house doctors would have offered outpatient appointments.

Multiphase CuInSe2 (CISe) nanoparticles including the CuSe phase are synthesized by the microwave-assisted solvothermal method. Without additional processing, multiphase CISe nanoparticles facilitate the solution-processed CISe absorber layer with a dense microstructure, large grains, high crystallinity, and composition controllability, which are essential for acceptable thin-film solar cell performance. The high performance, solution-processed CISe solar cell, with a conversion efficiency of 8.2%, is obtained through phase transformation, microstructural evolution, and composition adjustment by selenization (annealing under a Se atmosphere) at 530 °C.

Objectives: To compare plasma kisspeptin, serum leptin, and serum retinol-binding protein 4 (RBP4) levels in women with and without polycystic ovary syndrome (PCOS) and to correlate these among each other and with clinical, hormonal, and metabolic parameters. Methods: Ninety women, including 54 women with PCOS and 36 without PCOS, participated in this study. For all patients, history and physical examinations were performed and blood samples were collected between days 3 and 8 of a spontaneous bleeding episode in the PCOS group and during normal menses of controls. Plasma kisspeptin, serum leptin, and serum RBP4 levels were measured using specific commercial assays. Results: Kisspeptin, leptin, and RBP4 levels were significantly higher in the PCOS group than in controls. Kisspeptin and RBP4 levels were significantly higher among obese PCOS patients than controls. Leptin levels were higher among obese PCOS patients than non-obese PCOS patients or controls. Kisspeptin and leptin levels of PCOS patients were significantly correlated with RBP4 levels. When only obese PCOS patients were analyzed, kisspeptin levels correlated with only the free androgen index. Conclusions: These findings suggest that kisspeptin, leptin, and RBP4 are associated with metabolic disturbances in women with PCOS.

background: Recently, proteomic technologies have demonstrated that several proteins are differently expressed in various body fluids of patients with endometriosis compared with those without this condition. The aim of this study was to investigate proteins secreted in urine of patients with endometriosis using proteomic techniques in order to identify potential markers for the clinical diagnosis of endometriosis. methods: Urine samples were collected from women undergoing laparoscopy for different indications including pelvic masses, pelvic pain, suspicious endometriosis, infertility and diagnostic evaluation. Proteomic techniques and mass spectrometry were used to identify proteins secreted in the urine of the patients with and without endometriosis and quantification of identified protein was performed using western blot and specific commercial sandwich enzyme-linked immunosorbent assays (ELISA). results: Twenty-two protein spots were differentially expressed in the urine of patients with and without endometriosis, one of which was identified as urinary vitamin D-binding protein (VDBP). ELISA quantification of urinary VDBP corrected for creatinine expression (VDBPCr) revealed that urinary VDBP-Cr was significantly greater in patients with endometriosis than in those without (111.96+ 74.59 versus 69.90+ 43.76 ng/mg Cr, P ¼ 0.001). VDBP-Cr had limited value as a diagnostic marker for endometrioisis (Sensitivity 58%, Specificity 76%). When combined with serum CA-125 levels (the product of serum CA-125 and urinary VDBP-Cr), it did not significantly increase the diagnostic power of serum CA-125 alone. conclusions: Urinary VDBP levels are elevated in patients with endometriosis. They have limited value as a potential diagnostic biomarker for endometriosis but suggest it would be worthwhile to investigate other urinary proteins for this purpose.
