Long-term remission of infantile Takayasu arteritis associated with germline CBL syndrome after allogeneic hematopoietic stem cell transplantation: A case report and literature review.

Takayasu arteritis (TA) is a large-vessel vasculitis that rarely presents in infancy. Casitas B-lineage lymphoma (CBL) syndrome is a rare genetic disorder due to heterozygous CBL gene germline pathogenic variants that is characterized by a predisposition to develop juvenile myelomonocytic leukemia (JMML). Vasculitis, including TA, has been reported in several patients.

Gain enhancement of BiCMOS on-chip sub-THz antennas by mean of meta-cells.

A MM-loaded sub-THz on-chip antenna with a narrow beamwidth, 9 dB gain and a simulated peak efficiency of 76% at the center frequency of 300 GHz is presented. By surrounding the antenna with a single MM-cell ring defined solely on the top metal of the back-end of line, an efficient suppression of the surface waves is obtained. The on-chip antenna has been designed using IHPs 130 nm SiGe BiCMOS technology with a 7-layer metallization stack, combined with the local backside etching process aimed to creating an air cavity which is then terminated by a reflective plane.

[Inherited bleeding disorders in adolescents with excessive menstrual bleeding. Should we evaluate the fibrinolytic pathway?].

Introduction: Heavy Menstrual Bleeding (EMB) is a frequent problem in adolescence. The prevalence of inherited bleeding disorders (IBD) as a cause of EMB is not well established and the involvement of fibri nolytic pathway defects has been poorly explored.

Objective: To determine the prevalence of IBD and fibrinolysis defects in adolescents with EMBs.

Miniature Switchable Millimeter-Wave BiCMOS Low-Noise Amplifier at 120/140 GHz Using an HBT Switch.

A 120-140 GHz frequency-switchable, very compact low-noise amplifier (LNA) fabricated in a 0.13 µm SiGe:C BiCMOS technology is proposed. A single radio-frequency (RF) switch composed of three parallel hetero junction bipolar transistors (HBTs) in a common-collector configuration and a multimodal three-line microstrip structure in the input matching network are used to obtain a LNA chip of miniaturized size.

Mid-infrared optical characterization of thin SiN membranes.

The investigation of the optical constants (e.g., the refractive index n and the extinction coefficient κ) has been performed in the mid-infrared spectrum for various silicon nitride (SiN) configurations.

Advanced numerical investigation of the heat flux in an array of microbolometers.

The investigation of the thermal properties of an array of microbolometers has been carried out by mean of two independent numerical analysis, respectively the Direct-Simulation Monte Carlo (DSMC) and the classic diffusive approach of the Fourier's equation. In particular, the thermal dissipation of a hot membrane placed in a low-pressure cavity has been studied for different values of the temperature of the hot body and for different values of the pressure of the environment. The results for the heat flux derived from the two approaches have then been compared and discussed.

Experiments on MEMS Integration in 0.25 μm CMOS Process.

In this paper, we share our practical experience gained during the development of CMOS-MEMS (Complementary Metal-Oxide Semiconductor Micro Electro Mechanical Systems) devices in IHP SG25 technology. The experimental prototyping process is illustrated with examples of three CMOS-MEMS chips and starts from rough process exploration and characterization, followed by the definition of the useful MEMS design space to finally reach CMOS-MEMS devices with inertial mass up to 4.3 μg and resonance frequency down to 4.

[Heavy menstrual bleeding affects quality of life in adolescents].

Introduction: Heavy menstrual bleeding (HMB) occurs in 37% of adolescents and compromise their quality of life.

Objective: To measure the magnitude of the impact of the SME on the quality of life in adolescents.

Patients And Method: We interviewed adolescents diagnosed with HMB between 10 and 18 years old and one of their guardians.

[Renal function in pediatric patients with allogeneic hematopoietic progenitor cell transplantation].

Unlabelled: Patients with hematopoietic stem cell transplantation can develop some degree of renal failure. The aim of this descriptive study is to evaluate markers of kidney injury in pediatric patients undergoing allogeneic hematopoietic stem cell transplantation between 1991 and 2011.

Patients And Method: A descriptive study of pediatric patients with allogeneic transplant of hematopoietic precursors between 1991 and 2011.

Search for unrelated donor umbilical cord blood units for allogeneic stem cell transplantation: results in two time periods.

Unlabelled: Umbilical cord blood (UCB) banks have increased their stock worldwide in the past years. There are more than 230,000 available units today. The ideal UCB graft is a unit that is matched in five or six of six HLA.
