Stem cells protect the bronchial stump in rat, increasing Sox6, Col2a1, and Agc1 expression.

Background: Post-pneumonectomy bronchopleural fistulas (BPFs) are associated with high morbidity and mortality. Currently, since the management of BPFs is difficult to assess, the best therapeutic approach is prevention. Our objective was to evaluate the effects of adipose-derived stem cells (ASCs) on the healing of the bronchial stump in an experimental animal model.

Autologous platelet-poor plasma decreases the bronchial stump necrosis in rat.

Background: Necrosis of the bronchial stump is a very important trigger for bronchopleural fistula. The administration of local autologous platelet-poor plasma (PPP) could protect the bronchial stump.

Materials And Methods: Left pneumonectomy was performed in 25 Sprague-Dawley rats.

Searching for novel molecular targets of chronic rejection in an orthotopic experimental lung transplantation model.

Background: Chronic rejection (CR) is the main reason for the limited survival rates among lung transplant (LT) recipients. There remains no effective treatment for CR. The aim of this study was to identify new molecular mechanisms involved in CR by using DNA microarray analysis.

Technical modifications of the orthotopic lung transplantation model in rats with brain-dead donors.

Background: Microsurgical lung transplantation in rats has allowed us to obtain new knowledge about lung transplantation. However, some aspects in human transplantation technique still have not been included in this model, which could interfere with the clinical interpretation and extrapolation of results.

Methods: Twenty left lung transplantations were performed with a cuff technique and technical modifications, such as brain death induction, the control of ischemia time and retrograde perfusion in the donor and the controlled sequential reperfusion of the implanted lung in the recipient.

Severe compensatory hyperhidrosis following thoracic sympathectomy successfully treated with low doses of botulinum toxin A.

Compensatory hyperhidrosis is an adverse effect of thoracic sympathectomy that can be debilitating, which is why an efficient treatment is demanded. Botulinum toxin is an emerging treatment, not well known yet. We report two cases of compensatory hyperhidrosis following thoracic sympathectomy which were both treated with low doses of botulinum toxin A.

Primary frontal hyperhidrosis successfully treated with low doses of botulinum toxin A as a useful alternative to surgical treatment.

Frontal hyperhidrosis appears to be a special and rare form of focal hyperhidrosis. These patients may suffer greatly from the condition so an efficient treatment is highly demanded. Surgical treatment may solve this problem permanently, but the possibility of serious complications and low satisfactory results makes it less advisable than in other types of hyperhidrosis where surgery has shown great benefits.
