Additive manufacturing of metallic glass from powder in space.

Additive manufacturing of metals - and in particular building with laser-based powder bed fusion - is highly flexible and allows high-resolution features and feedstock savings. Meanwhile, though space stations in low Earth orbit are established, a set of visits to the Moon have been performed, and humankind can send out rovers to explore Venus and Mars, none of these milestone missions is equipped with technology to manufacture functional metallic parts or tools in space. In order to advance space exploration to long-term missions beyond low Earth orbit, it will be crucial to develop and employ technology for in-space manufacturing (ISM) and in-situ resource utilisation (ISRU).

Comparative evaluation of five chromogenic media for detection, enumeration and identification of urinary tract pathogens.

Five chromogenic agar plates--CPS ID2 medium (bioMérieux, France), CHROMagar Orientation medium (Becton Dickinson, France), UriSelect3 medium (Sanofi Diagnostics Pasteur, France), Rainbow Agar UTI medium (Biolog, USA) and Chromogenic UTI medium (Oxoid, Germany)--for the detection, enumeration and direct identification of urinary tract pathogens were compared using 443 urine specimens at two hospital laboratories. The enumeration of microorganisms was consistent on the five media for 403 of the 477 (84.5%) microorganisms.

[Spontaneous rupture of the esophagus diagnosed late. Recovery by directed fistulization].

Spontaneous rupture of the oesophagus is uncommon and is difficult to diagnose in the early stage. Clinical signs are lacking or incomplete, causing a delay in diagnosis and therapy which requires both intensive medical care and surgery. The surgical procedure depends on the time lapse to diagnosis.

[Endometriosis and diaphragmatic defect in catamenial pneumothorax].

Two cases of catamenial pneumothorax are reported, a rare condition characterized by its sudden occurrence in a female patient between the ages of 30 and 40 years, always at the onset of the menstrual cycle. Its exact origin is unknown, but the frequent co-existence of endometriosis and a defect in the diaphragm suggests that endometriosis may be important in the etiology both of the pneumothorax and the diaphragmatic lesion. Pelvic endometriosis was present in both our patients, one of whom also had diaphragmatic endometriosis.

[Isolated pulmonary choriocarcinoma].

The author report a case of isolated choriocarcinoma of the lung revealed in a young woman by a tumoral syndrome of the right base with haematoma. The diagnosis of isolated pulmonary choriocarcinoma was based on the lack of previous gynaecological history and tumour, on the singleness of the lung tumour at CT, and on the high initial beta-CGH level (3,300 ng/ml) in the absence of pregnancy. Surgical resection confirmed the diagnosis and lowered the beta-CGH level to 7 ng/ml.
