The purpose of this study was to introduce the technique for distraction lengthening of the traumatic amputation stumps of distal phalanges less than 10 mm long by using the Ilizarov minifixator (Ito Medical Instruments, Tokyo, Japan) and to report the treatment results and the problems we encountered. Six patients (3 men and 3 women) underwent lengthening of the traumatic amputation stumps of distal phalanges using the Ilizarov minifixator. The mean pre-operative length of the distal phalanges was 6.0 mm and the mean deficiency in length was 9.5 mm compared with the contralateral finger or thumb. In 5 of the 6 patients callus lengthening was completed without early consolidation or bone failure related to the traction wires. The mean gain in lengthening of the distal phalanx was 6.8 mm and the mean final length of the distal phalanx was 12.8 mm. After surgery 4 patients had onychoplasty and advancement flap coverage of the distal phalangeal tip because of excessive skin tension and 1 patient had arthrodesis because of flexion contracture of the distal interphalangeal joint. The patients were satisfied with the cosmetic improvement of their fingertips. Although this callus distraction method required multiple surgical procedure...Continue Reading

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

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.
