A 29-year-old man with chronic pulmonary emboli presented to the hospital with progressive pleuritic chest pain. He was in acute right ventricular failure and received intrapulmonary arterial tissue plasminogen activator. Massive hemoptysis developed, requiring emergent thromboendarterectomy. A clot was visualized in the main left pulmonary artery that had formed a bronchovascular fistula into the left upper lobe bronchus. Pathology of the clot revealed fibrinopurulent exudate and Gram-positive cocci. The left pulmonary artery was repaired with a pericardial patch, and the left upper lobe was oversewn with subsequent left upper lobectomy. The patient was discharged home on postoperative day 23.

Background: Chronic pulmonary abscess usually results from bacterial or mycobacterium infection, but rarely from aspergillosis. Chronic pulmonary aspergillosis is usually found in a person with structural lung disease or immunocompromise. Here, we report a case of chronic lung abscess of aspergillosis without immunocompromise, structural lung diseases or even clinical symptoms.

The degeneration of pyramidal tracts has been reported in frontotemporal lobar degeneration with TDP-43 (TAR DNA-binding protein 43) pathology (FTLD-TDP) type C. Herein, we examined the detailed pathology of the primary motor area and pyramidal tracts in the central nervous system in four autopsy cases of FTLD-TDP type C, all of which were diagnosed by neuropathological, biochemical, and genomic analyses. Three patients showed right dominant atrophy of the frontal and temporal lobes, while the other patient showed left dominant atrophy.

Background: Paediatric upper limb fractures are commonly treated with Kirschner (K) wire fixation, which can be buried or left exposed. Although both techniques are widely used, controversy remains regarding infection risk, complications, and other clinical outcomes between buried and exposed K-wires. This systematic review and meta-analysis aimed to compare infection rates and secondary outcomes between buried and exposed K-wires in paediatric upper limb fractures located distal to and including the elbow, and proximal to the carpus.

A boy with bilateral congenital anomalies of the upper extremities with transverse absence of the left arm (agenesis) and absence of right thumb (disgenesis), fixed elbow in extension due to humeroradial synostosis thought that the humerus was intact. His wrist could move passively with 50° flexion, 0° extension, and 70° radial deviation. The other 4 fingers were intact, 4-5 metatarsal bones were in synostosis, and the fifth finger was clinodactyly.
