Single needle hemodialysis: is the past the future?

J Nephrol 2020 Feb 19;33(1):49-58. Epub 2019 Sep 19.

Nephrology Section, 0K12, Department of Internal Medicine, University Hospital Ghent, C Heymanslaan, 10, 9000, Ghent, Belgium.

Whereas the usual way to gain access to the vascular bed for hemodialysis is by inserting two needles, an alternative option based on the introduction of only one needle has been available for several decades. Although single needle hemodialysis gradually lost popularity in the early nineties of last century, this option now seems to make a come-back, with the current change in patient mix towards more elderly and cardio-vascular disease and the appearance of more flexible hardware. Single needle hemodialysis offers several advantages, such as the possibility to puncture small or maturing access systems, a decrease in number of punctures with less potential access damage and subsequent complications, the avoidance of central vein catheter use, and an improved quality of life by reducing puncture-related pain, stress and complications.

Nondestructive, multiplex three-dimensional mapping of immune infiltrates in core needle biopsy.

Lab Invest 2019 09 6;99(9):1400-1413. Epub 2018 Nov 6.

Department of Molecular Genetics and Cell Biology, The University of Chicago, Chicago, IL, USA.

Enumeration of tumor-infiltrating lymphocytes (TILs) in H&E stained tissue sections has demonstrated limited value in predicting immune responses to cancer immunotherapy, likely reflecting the diversity of cell types and immune activation states among tumor infiltrates. Multiparametric flow cytometry enables robust phenotypic and functional analysis to distinguish suppression from activation, but tissue dissociation eliminates spatial context. Multiplex methods for immunohistochemistry (IHC) are emerging, but these interrogate only a single tissue section at a time. Read More

A new technique of ultrasound guided percutaneous renal biopsy by perforated probe and perpendicular needle trajectory.

Arch Ital Urol Androl 2018 Mar 31;90(1):29-33. Epub 2018 Mar 31.

Hemodialysis Unit, S. Donato Hospital, Arezzo.

The percutaneous biopsy of native kidneys according to the classical methodology is performed under real time ultrasound guidance with the needle introduction along a trajectory of about 30°, aimed to the lower pole of the kidney. Recently, a variant of the classical technique has been introduced by which a perforated ultrasound probe is used to guide the needle along a perpendicular trajectory to the terminal section of the lower kidney pole where the front and back margins of the cortical kidney tissue join each other without renal sinus interposition so to offer to the needle a 3-4 cm thick cortical tissue front which allows to obtain a cortical tissue sample suitable for histological examination even with a single needle pass, while at the same time limiting the possibility of damaging the smaller kidney calices of the lower group whose lesion causes hematuria. In this paper, we present a large survey (50 patients) to compare to data from the literature obtained by using similar needle gauge and with a similar follow-up period after biopsy. Read More
