Sacrococcygeal malignant germ cell tumor (SC-MGCT) with intraspinal extension

This paper describes a new brazing recipe for making intermetallic-free and ductile niobium-316L stainless steel transition joints for application in superconducting radio frequency cavities. Brittle Fe-Nb intermetallic compounds have remained a matter of concern in niobium-stainless steel joints made with the global practice of vacuum brazing that uses pure copper as the filler metal. Important measures adopted to suppress brittle intermetallic formation include the use of nickel plating on mating stainless steel surface as a diffusion barrier and wettability enhancer, and lower temperature, titanium-free brazing filler metal BVAg8. The resultant joints were free of brittle intermetallic compounds, which translated into ductile fracture in tensile and shear tests. The brazed joints displayed tensile and shear strengths of 150–191 and 103–118 MPa, respectively. The joints demonstrated a required level of hermeticity for service in ultrahigh vacuum; a capability to withstand degassing heat treatment at 873 K, a mandatory step for superconducting radio frequency cavities; and also low-cycle thermal fatigue between the room temperature and the liquid nitrogen temperature. The new vacuum brazing recipe marks a significant advancement over existing global practice to make sound and ductile niobium-316L stainless steel transition joints with improved microstructural characteristics.

New Brazing Recipe for Ductile Niobium-316L Stainless Steel Joints

To assess whether symptomatic unilateral ureteropelvic junction obstruction (SUUPJO) affects somatic growth and, if so, the parameters associated with it, 61 children (54 boys and 7 girls) who underwent pyeloplasty for SUUPJO without any other associated urological abnormalities were retrospectively studied. Height was compared with standard growth charts and was considered to be affected if it was below 2.00 Z-score. Such children were considered group B and the rest group A. Mean (±SD) age at presentation and mean (±SD) split renal function (SRF) (%) of the affected kidney were 6.0 ± 4.0 years and 27.3 ± 13.2, respectively, for the entire group. Somatic growth was affected in 16 (12 boys, 4 girls) children (26.2%). Urinary tract infection (UTI) was the presenting symptom in 11 (69%) and 5 (11%) children in groups B and A, respectively. Impaired somatic growth had no association with age at presentation or SRF, but a significant association (P < 0.001) was found with UTI. The mean post-surgery height percentile (2.92 ± 4.85) over a mean follow-up of 3.37 ± 1.86 years was significantly (P < 0.005) better compared with pre-surgery height percentile (0.67 ± 0.96) in group B, indicating catch-up growth after surgery. In SUUPJO, somatic growth is affected. Presentation with UTI has a significant association, and height significantly improves after surgery in these patients.

Urinary-tract infection affects somatic growth in unilateral symptomatic hydronephrosis

Two uncommon cases of locally invasive pulmonary inflammatory myofibroblastic tumor are reported. Diagnosis was established by a prior thoracotomy and incisional biopsy. Complete excision was curative and both children remain asymptomatic at last follow up.
