Massive facial keloid precipitated by chronic suppuration and mechanical skin traction: A case report.

Keloids are benign fibroproliferative tumours with a high recurrence rate of 20%-100%, therefore, multimodal treatment is recommended. We report the case of an exceptionally large facial keloid precipitated by a vicious cycle of chronic inflammation and mechanical skin traction and discuss the management challenges in a low resource setting. A 67-year-old man presented with a 10-year history of a facial keloid that rapidly enlarged to 2,800 g in 2 years causing difficulties eating, speaking, dressing, head movements and breathing.

Rapid sequencing-based diagnosis of infectious bacterial species from meningitis patients in Zambia.

Objectives: We have developed a portable system for the rapid determination of bacterial composition for the diagnosis of infectious diseases. Our system comprises of a nanopore technology-based sequencer, MinION, and two laptop computers. To examine the accuracy and time efficiency of our system, we provided a proof-of-concept for the detection of the causative bacteria of 11 meningitis patients in Zambia.
