Measured Levels of Human Adipose Tissue-Derived Stem Cells in Adipose Tissue Is Strongly Dependent on Harvesting Method and Stem Cell Isolation Technique.

Background: Adipose tissue-derived stem cells are of great interest because of their properties of immune modulation, tissue regeneration, and multipotent differentiation. To advance development of stem cell-based treatments, determination of the physiologic concentration of adipose tissue-derived stem cells in human adipose tissue is relevant for proper guidance of stem cell treatment dosage, oncologic safety, and evaluation of efficacy.

Methods: A prospective comparative case-control study of 20 patients was conducted to determine the yield of adipose tissue-derived stem cells in periumbilical adipose tissue harvested by the widely used method of aspiration and in structurally intact adipose tissue harvested by excision.

Laser-assisted indocyanine green angiography in implant-based immediate breast reconstruction: a retrospective study.

Objective: Necrosis in implant-based immediate breast reconstruction is a feared complication. Accurate evaluation of mastectomy skin flaps per-operatively is necessary to decrease this risk. The present study is the first in Scandinavia to review the effects of perioperative evaluation with laser-assisted indocyanine green fluorescence angiography (LA-ICGA).

[Scar prophylaxis and treatment].

Scarring is an expected result of trauma to the skin. Scars are a heterogenic group varying from small white non elevated scars to hypertrophic scars and keloids. Many different algorithms for scar prophylaxis and treatment have been presented in the literature.

The versatility of autologous fat transplantation in correction of facial deformities: a single-center experience.

Deformities in the craniofacial region are of great social and functional importance. Several surgical techniques have been used to treat such pathologies often with high morbidity and lacking the ability to address smaller contour defects. The minimally invasive technique of fat transplantation has evolved rapidly within the last few decades.

Delayed total breast reconstruction with brava.

Several surgical procedures exist in regard to reconstruction of the breast after mastectomy. The use of Brava a vacuum-based external soft-tissue expansion system in combination with fat transplantation is a less documented but viable option in treating patients after mastectomy. We share our experience in treating a 57-year-old patient with mastectomy, describing the complications and pitfalls we experienced when using the Brava system in combination with fat transplantation.

Occult distal urethral carcinoma presenting as metastatic carcinoma in the inguinal lymph nodes.

A 65-year-old man presented with metastatic squamous cell carcinoma in the inguinal lymph nodes from an unknown primary tumour. The initial work-up lacked clinical examination of the glans penis, in part due to the patient having phimosis. More than a year after presentation, a primary tumour, located distally on the penis, was diagnosed.
