We evaluated the results of lengthening of the phalanges by callus distraction in traumatic amputations of the fingers. We treated traumatic amputations of 16 fingers of 13 male patients (mean age 27.7 years; range 12 to 43 years) by callotasis of the phalanges. Callus distraction was performed with a rate of 1 mm/day using a unilateral dynamic external fixation device. The mean follow-up period was 42 months (range 12 to 80 months). The mean lengthening was 24 mm (range 18 to 26 mm) and 21 mm (range 18 to 26 mm) for the thumbs and the other fingers, respectively. The achieved thumb length provided adequate depth and width of the first web space and enabled functional improvement in the ability of gripping, and pulp-to-pulp and pulp-to-side pinching. In the absence of flexor pollicis longus, the mean strength of the thumbs was 7 kg (range 5 to 9 kg), amounting to 65% of the normal side. Lengthening of the other fingers resulted in improved functioning of the hand. The mean healing index (number of months per centimetre of lengthening) was 1.7 months/cm (range 1.6 to 2.1 months/cm) and 1.6 months/cm (range 1.4 to 1.9 months/cm) in the thumbs and the other fingers, respectively. Pin tract infections were observed in four phalange...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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. 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.

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
