Current Systemic Treatment Options for Tenosynovial Giant Cell Tumor/Pigmented Villonodular Synovitis: Targeting the CSF1/CSF1R Axis.

Adequate surgical resection remains the treatment of choice for tenosyovial giant cell tumor (TGCT). However, diffuse type TGCT (D-TGCT) is more difficult to resect and has a higher rate of recurrence (up to 50 %), which is often multiple. D-TGCT is rarely lethal and only rare cases of metastases have been described.

Risk Factors for Autoimmune Diseases Development After Thrombotic Thrombocytopenic Purpura.

Autoimmune thrombotic thrombocytopenic purpura (TTP) can be associated with other autoimmune disorders, but their prevalence following autoimmune TTP remains unknown. To assess the prevalence of autoimmune disorders associated with TTP and to determine risk factors for and the time course of the development of an autoimmune disorder after a TTP episode, we performed a cross sectional study. Two-hundred sixty-one cases of autoimmune TTP were included in the French Reference Center registry between October, 2000 and May, 2009.

Association of type and location of BRCA1 and BRCA2 mutations with risk of breast and ovarian cancer.

Importance: Limited information about the relationship between specific mutations in BRCA1 or BRCA2 (BRCA1/2) and cancer risk exists.

Objective: To identify mutation-specific cancer risks for carriers of BRCA1/2.

Design, Setting, And Participants: Observational study of women who were ascertained between 1937 and 2011 (median, 1999) and found to carry disease-associated BRCA1 or BRCA2 mutations.

Metastatic renal cell carcinoma treated sequentially with multiple VEGF receptor-targeted inhibitors--a case report.

Six targeted agents [sorafenib, sunitinib, temsirolimus, bevacizumab (plus interferon), everolimus and pazopanib] have been approved for the treatment of patients with metastatic renal cell carcinoma. As disease progression is inevitable, most patients will receive several lines of treatment. However, the choice regarding which sequence of drugs to use remains unclear, particularly concerning the drug class, i.

Long-term follow-up of 1036 cerebral aneurysms treated by bare coils: a multicentric cohort treated between 1998 and 2003.

Background And Purpose: The endovascular treatment (EVT) of cerebral aneurysms has experienced a revolution since 1991 with the introduction of platinum coil technology. During the past 10 years, there has been significant study of the feasibility of this technique, and clinical results of EVT have been published. The long-term durability of Guglielmi detachable coil (GDC) embolization of cerebral aneurysms still remains unknown.

Development and validation of an immunoassay for identification of recent human immunodeficiency virus type 1 infections and its use on dried serum spots.

The objective was to develop and to validate an immunossay to identify recent human immunodeficiency virus type 1 (HIV-1) infections that can be used on dried serum spots (DSS). A single, indirect enzyme-linked immunosorbent assay was developed to quantify antibodies toward four HIV-1 antigens: consensus peptides of the immunodominant epitope of gp41 (IDE), consensus V3 peptides, recombinant integrase, and recombinant p24. The parameters of the logistic regression used to classify the samples were estimated on a training sample (210 serum samples) using resampling techniques to get stable estimates and then applied to a validation sample (761 serum samples).

A multicenter study of 705 ruptured intracranial aneurysms treated with Guglielmi detachable coils.

Background And Purpose: The long-term durability of Guglielmi detachable coil (GDC) embolization of cerebral aneurysms is still unknown. The purpose of this study was to evaluate the stability of anatomic occlusion of aneurysms treated with GDCs and assess the rate of recanalization and re-treatment.

Methods: A multicenter study involving 650 patients with 705 ruptured aneurysms treated with GDCs between January 1998 to May 2003 was conducted.

Efficacy of IVF using frozen donor semen in cases of previously failed DI cycles compared with tubal infertility: a cohort study.

A cohort follow-up study was designed to compare the efficacy of IVF using frozen donor semen (IVF-D) following previously failed DI cycles (unexplained female infertility) and direct IVF-D treatment because of tubal infertility (control group). The cohort comprised 189 couples initiating IVF-D after previously failed DI cycles (n = 126) or directly (n = 63). Couples were followed until completion (success or drop-out for personal or medical reasons).

[Antibiotic use: excesses and consequences].

Antibiotic use in France is excessive. This statement is regularly expressed. The comparison with usage in other European countries, the frequency of use in viral infections, the misuse, specifically in the duration of treatment is easy proof of this.

Radiosensitivity of rat mammary tumors correlates with early vessel changes assessed by power Doppler sonography.

Objective: To investigate the changes occurring in the vascularization of tumors during irradiation, we used a model of autochthonous mammary tumors in rats and assessed early vascular changes after irradiation by power Doppler sonography.

Methods: Mammary tumors were induced in 24 female Sprague Dawley rats by a single subcutaneous injection of N-nitroso N-methyl urea. After tumor areas reached 1 cm2, the animals received a single fraction of 18-Gy radiation or intraperitoneal saline injection.

Achievement of second parenthood in an ART programme using frozen donor semen: cohort follow-up.

Background: This study was designed to determine the efficacy of a programme using frozen donor semen in a cohort of patients returning for treatment after previously conceiving through donor insemination (DI).

Methods: The cohort included 222 couples with secondary infertility (previous live birth) in one University Hospital Centre. The treatment sequence involved DI cycles until completion.

Color Doppler imaging of orbital vessels: personal experience and literature review.

Many Doppler imaging studies have been performed in recent years in a large number of ocular disorders because of improvements in the Doppler equipment used for detecting and measuring the low blood-flow velocities that are a requisite for the quantitative evaluation of blood flow in the orbital vessels. The ophthalmic artery, central retinal artery and vein, posterior ciliary arteries, and the superior ophthalmic vein can be easily identified using color Doppler sonography. The changes in local blood flow in these vessels assessed by spectral analysis pulsed Doppler sonography have been used to characterize and to obtain new insights into different nontumoral vascular disorders including carotid artery stenosis, central retinal vein occlusion, giant cell arteritis, glaucoma, diabetes, fistulas, and tumoral processes of the eye and orbit.

The internal acoustic meatus and its meningeal layers: a microanatomical study.

Object: The authors studied the cadaveric heads of 22 adults to describe the internal acoustic meatus (IAM) and its contents. Special attention was paid to the length of the arachnoidal and dural sheaths surrounding the neural structures, including the vestibular ganglion. An additional goal of this study was to verify anatomically the concept of arachnoidal duplication, which is reputedly induced by medial growth of vestibular neuromas and helpful in atraumatic dissection.

Follow up by colour Doppler imaging of 102 patients with retinal vein occlusion over 1 year.

Background/aim: Retinal vein occlusion (RVO) is one of the most frequent ocular vascular diseases and leads to severe vision impairment. Colour Doppler imaging (CDI) is the first method which allows distinct evaluation of arterial and venous velocities in RVO. CDI is valuable for diagnosis of RVO and shows the effects of isovolaemic haemodilution.

Cohort follow-up of couples with primary infertility in an ART programme using frozen donor semen.

Background: This study was designed to determine the crude cumulative live-birth rates in a cohort initiating frozen donor semen treatment until completion.

Methods: This cohort study included 588 couples with primary infertility in one University Hospital centre. The treatment sequence involved first artificial insemination (AID) followed by IVF if necessary (IVF-D).

tRNA gene clusters at the 3' end of rRNA operons are specific to virulent subgroups of Streptococcus agalactiae strains, as demonstrated by molecular differential analysis at the population level.

The aim of this work was to characterize a 2.4 kb randomly amplified polymorphic DNA (RAPD) fragment described as a marker for a phylogenetic group of Streptococcus agalactiae strains significantly associated with neonatal meningitis. This fragment was analysed by cloning and sequencing, and showed that two types of tRNA gene cluster flank the 3' end of the rRNA operons in S.

Two successive hepatitis C virus infections in an intravenous drug user.

We report the case of an occasional intravenous drug user who developed two successive hepatitis C virus (HCV) infections. The first infection led to seroconversion (anti-HCV antibodies detected) and the detection of HCV RNA in serum. After a spontaneous recovery (normalization of alanine aminotransferase levels and HCV RNA clearance), a second HCV infection was observed, with the recurrence of HCV viremia.

Capnocytophaga ochracea: characterization of a plasmid-encoded extended-spectrum TEM-17 beta-lactamase in the phylum Flavobacter-bacteroides.

A plasmid-encoded extended-spectrum TEM beta-lactamase with a pI of 5.5 was detected in a Capnocytophaga ochracea clinical isolate. The bla gene was associated with a strong TEM-2 promoter and was derived from bla(TEM-1a) with a single-amino-acid substitution: Glu(104)-->Lys, previously assigned to TEM-17, which is thus the first TEM beta-lactamase to be reported in the phylum Flavobacter-Bacteroides.

Familial form of intracranial cavernous angioma: MR imaging findings in 51 families. French Society of Neurosurgery.

Purpose: To analyze the magnetic resonance (MR) imaging features of familial cerebral cavernous angioma in non-Hispanic families.

Materials And Methods: Between November 1996 and June 1997, 51 non-Hispanic families with familial cavernous angioma were identified. Cerebral MR images in 83 symptomatic subjects and 73 asymptomatic subjects were reviewed.

Initial color Doppler findings in retinal vein occlusion.

Purpose: We assessed early hemodynamic characteristics of various types of retinal vein occlusion using color Doppler imaging and spectral analysis.

Methods: We measured the maximum systolic and diastolic blood flow velocities and the resistance index (RI) in the central retinal artery and the maximum and minimum blood flow velocities in the central retinal vein of affected eyes and contralateral unaffected eyes in 102 adults (63 men and 39 women; mean age, 61 +/- 14.6 years) who presented with retinal vein occlusion.

Genetic features of Streptococcus agalactiae strains causing severe neonatal infections, as revealed by pulsed-field gel electrophoresis and hylB gene analysis.

A collection of 114 independent Streptococcus agalactiae strains, including 54 strains isolated from the cerebrospinal fluid (CSF) samples of neonates and 60 strains from asymptomatic patients, was characterized by pulsed-field gel electrophoresis (PFGE) of DNA restricted with SmaI and by PCR analysis of the hylB gene. All strains were previously studied by multilocus enzyme electrophoresis (MLEE) (R. Quentin, H.

The kinetics of antibodies against hepatitis C virus may predict viral clearance in exposed hemophiliacs.

Several studies have reported the spontaneous loss of hepatitis C virus (HCV) antibodies in HCV-exposed persons. However, the relationship between seroreversion and spontaneous virus clearance has yet to be precisely determined in a single homogeneous population of untreated immunocompetent patients. In this study, 32 human immunodeficiency virus-seronegative hemophiliacs who had been exposed to HCV were followed for a mean duration of 141 months; 22 remained chronic carriers (68.
