Os peroneum imaging: normal appearance and pathological findings

The os peroneum (OP) is a small sesamoid bone located inside the peroneus longus tendon (PLT), close to the cuboid. The OP can be the cause of pain and can be associated with lesions of the PLT. OP involvement in PLT disorders is frequently misdiagnosed by radiologists. Painful os peroneum syndrome (POPS) refers to a variety of conditions presenting with pain localized on the ...

X-ray absorption variability in NGC 4507

We present a complete spectral analysis of an XMM–Newton and Chandra campaign of the obscured AGN in NGC 4507, consisting of six observations spanning a period of six months, ranging from 2010 June to December. We detect strong absorption variability on time-scales between 1.5 and 4 months, suggesting that the obscuring material consists of gas clouds at parsec-scale distance. The ...

On the origin of soft X-rays in obscured AGN: answers from high-resolution spectroscopy with XMM–Newton

Matteo Guainazzi 0 Stefano Bianchi 0 0 European Space Astronomy Centre of ESA , Apartado 50727, E-28080 Madrid , Spain A B S T R A C T We present results of a high-resolution soft X-ray (0.2-2 keV

On the peculiar properties of the narrow-line quasar PG 1543+489

We present the analysis of four XMM–Newton observations of the narrow-line quasar PG 1543+489 at z= 0.400 carried out over a rest-frame time-scale of about 3 yr. The X-ray spectrum is characterized by a broad, relativistic iron Kα emission line and a steep photon index, which can be both explained by a ionized reflection model, where the source of X-ray photons is presumably very ...

High-resolution X-ray spectroscopy and imaging of Mrk 573

We present a detailed analysis of the XMM–Newton Reflection Grating Spectrometer (RGS) high-resolution X-ray spectra of the Seyfert 2 galaxy, Mrk 573. This analysis is complemented by the study of the Chandra image and its comparison to optical (Hubble Space Telescope) and radio (Very Large Array) data. The soft X-ray emission is mainly due to gas photoionized by the central active ...

A multiwavelength map of the nuclear region of NGC 7582

We have performed a detailed analysis of the Chandra and Hubble Space Telescope (HST) images of the Seyfert 2 galaxy NGC 7582. The dust lane, as mapped by the HST near-infrared and optical images, strongly influences the morphology of the soft X-ray emission, being spatially coincident with excess of X-ray absorption. Two ‘hotspots’, i.e. regions where emission from higher ...

The XMM–Newton view of Mrk 3 and IXO 30

We present the analysis of the XMM–Newton European Photon Imaging Camera (EPIC) pn spectrum of the Seyfert 2 galaxy Mrk 3. We confirm that the source is dominated by a pure Compton reflection component and an iron Kα line, both produced as a reflection from a Compton-thick torus, likely responsible also for the large column density (1.36+0.03−0.04× 1024 cm−2) which is pierced by ...

Fe xxv and Fe xxvi lines from low-velocity, photoionized gas in the X-ray spectra of active galactic nuclei

We have calculated the equivalent widths of the absorption lines produced by Fexxv and Fexxvi in a Compton-thin, low-velocity photoionized material illuminated by the nuclear continuum in active galactic nuclei. The results, plotted against the ionization parameter and the column density of the gas, are a complement to those presented by Bianchi & Matt for the emission lines from ...

Evaluation of a new questionnaire for the presurgical diagnosis of bladder endometriosis

BACKGROUND The main objective was to evaluate the diagnostic accuracy of a new questionnaire for the presurgical diagnosis of bladder endometriosis in patients with a high suspicion index for this disease. METHODS We included all patients of age <40 years undergoing laparoscopy or laparotomy for chronic pelvic pain. We partially modified the American Urologic Association Symptom ...

Laparoscopic creation of a neovagina in a woman with a kidney transplant: Case Report

The successful use of Vecchietti's technique for creating a neovagina in a case of Rokitansky syndrome with an associated transplanted kidney is reported. The technique is performed by means of a laparoscopic approach, adapted to the special anatomical situation, in order to avoid renal injuries. The accomplishment of a normally functioning neovagina, with no intra-operative or ...

Pre-operative assessment of bladder endometriosis

The aim of our study was to verify the reliability of transvaginal ultrasonography in the pre-operative evaluation of bladder endometriosis. Six patients with suspected bladder endometriosis were studied. At referral to our department all six women underwent magnetic resonance imaging (MRI), transabdominal and transvaginal ultrasonography, cystoscopy and descending urography. ...

Effects of 3 month therapy with danazol after laparoscopic surgery for stage III/IV endometriosis: a randomized study

The effect of treatment with danazol was evaluated with respect to expectant management after laparoscopic conservative surgery. All patients conservatively operated at laparoscopy for stage III–IV endometriosis from July 1994 to October 1996 were requested to enter the study. Patients who underwent surgery for recurrent endometriosis were excluded from the study, as well as ...

Residual uterine septum of less than 1 cm after hysteroscopic metroplasty does not impair reproductive outcome

The objective of this study was to ascertain if incomplete correction leaving a residual uterine septum of ≤1 cm affects fertility outcome. Reproductive outcome in 17 women with a residual septum of between 0.5 cm and 1 cm after hysteroscopic metroplasty was compared to that in 51 women with no residual septum or one of 1 cm then underwent a second operative hysteroscopy to ...

Extracorporeal dialysis: techniques and adequacy

Introduction and Aims: There is no consensus on the best method to quantify hemodialysis and the optimal dosage of hemodialysis. Urea is the substance most often measured as a surrogate for the clearance of small molecules. In particular, Kt/V, that is the dialyzer clearance of urea, multiplied by the length of the dialysis session, divided by the volume of distribution of urea, is ...
