Novel homozygous missense mutation in ABCA3 protein leading to severe respiratory distress in term infant.

BMJ Case Rep 2020 Oct 10;13(10). Epub 2020 Oct 10.

Neonatology, Madhukar Rainbow Children Hospital, Delhi, India.

The term baby presented with respiratory distress with X-ray pictures consistent as hyaline membrane disease (HMD). Baby was ventilated and treated with surfactant. Because of the persistence of high ventilation needs with X-ray pictures consistent with HMD with a transient response to surfactant every time, the possibility of an inherited disorder of surfactant metabolism was kept.

Tension pneumocephalus, an uncommon complication of oxygen therapy in preterm newborns. Presentation of a case and literature review.

Neurocirugia (Astur : Engl Ed) 2021 Mar-Apr;32(2):84-88. Epub 2019 Nov 26.

Servicio de Neurocirugía, Complejo Hospitalario Universitario de Santiago de Compostela, Santiago de Compostela, A Coruña, España.

Tension pneumocephalus is an extremely rare complication of positive-pressure ventilation in neonates, the diagnosis of which requires a high degree of clinical suspicion. We present the case of a preterm newborn, who received high-flow nasal cannula oxygen therapy because of hyaline membrane disease, due to his prematurity, and developed clinical signs of intracranial hypertension. Transfontanellar ultrasound and cranial CT scan revealed significant tension pneumocephalus, which was evacuated with direct needle puncture through the anterior fontanelle. Read More

Tenosynovial Giant Cell Tumor, Localized Type With Extensive Chondroid Metaplasia: A Case Report With Immunohistochemical and Molecular Genetic Analysis.

Int J Surg Pathol 2020 Jun 26;28(4):447-453. Epub 2019 Nov 26.

Shimane University, Izumo, Shimane, Japan.

Tenosynovial giant cell tumor (TSGCT) of localized type is a common disease occurring mostly in the hands. Diagnosis of this tumor is relatively easy to render with hematoxylin-eosin-stained sections as compared with that of TSGCT of diffuse type. However, very rare cases with chondroid metaplasia that have recently been reported mainly in diffuse type can make pathological differentiation from soft tissue cartilaginous tumors extremely difficult.
