Abstract

To discuss the management of vascular crisis of free flaps after reconstruction of head and neck defects caused by tumor resection. A total of 259 cases of free flap reconstruction performed in the Cancer Hospital of Chinese Academy of Medical Sciences from 2010 to 2013 were retrospectively analyzed, including 89 cases of anterolateral thigh flaps, 48 cases of radial forearm flaps, 46 free fibula flaps, 5 cases of inferior epigastric artery perforator flaps, 5 cases of free latissimus dorsi flaps, one case of lateral arm flap, and one case of medial femoral flap. The surveillance frequency of free flaps was q1h on post-operative day (POD) 1, q2h on POD 2 and 3, and q4h after POD 3. Vascular crises were reviewed for analysis. The incidence rate of vascular crisis was 8.1% (21/259), with 15 males and 6 females. The average age was 54.8 years old (17-68), and the average time of vascular crisis was 100.8 h post-operation (3-432). There were 7 cases of free jejunum flaps and 14 dermal free flaps. Seven of these 21 cases with vascular crisis were rescued by surgery. The success rate of salvage surgery within 72 hours from the primary operation was 54.5% (6/11), significantly higher than that of salvage surgery performed later than 7...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
