[Safety of modified T-piece resuscitator versus nasal cannula oxygen in electronic bronchoscopy for infants: a prospective randomized controlled study].

Objectives: To optimize the oxygen therapy regimens for infants with pulmonary diseases during bronchoscopy.

Methods: A prospective randomized, controlled, and single-center clinical trial was conducted on 42 infants who underwent electronic bronchoscopy from July 2019 to July 2021. These infants were divided into a nasal cannula (NC) group and a modified T-piece resuscitator (TPR) group using a random number table.

Clinical and genetic analysis of nonketotic hyperglycinemia: A case report.

Background: Nonketotic hyperglycinemia (NKH) is a rare autosomal recessive genetic disorder of abnormal glycine metabolism caused by insufficient activity of the glycine cleavage enzyme system. Glycine is believed to function mainly as an inhibitory neurotransmitter, but it can also act as a co-agonist of the N-methyl-D-aspartate (NMDA) receptor. The accumulation of a large amount of glycine in the brain leads to neuronal and axonal injury overactivation of NMDA receptors located in the hippocampus, cerebral cortex, olfactory bulb, and cerebellum and to stimulation of the inhibitory function of glycine receptors located in the spinal cord and brain stem, resulting in central apnea, hiccups, and hypotonia in the early stage of the disease.

Disseminated bloodstream infection in a child with acute myeloid leukemia: A case report.

Background: Disseminated is rare in healthy children. Children with hematological tumors may have secondary fungal infections, including infections which are due to tumor bone marrow infiltration or prolonged bone marrow suppression after chemotherapy. Because of the lack of typical clinical manifestations and effective antifungal drugs, early diagnosis and treatment of the disease are difficult, and the prognosis is poor.

[Endovascular repair for isolated iliac artery aneurysm].

Objective: To evaluate the short and middle-term efficacies of endovascular repair for isolated iliac artery aneurysms (IIAAs).

Methods: Retrospective analyses were performed for the clinical and follow-up data of 27 patients undergoing endovascular repair at Department of Vascular Surgery, Affiliated Zhongshan Hospital, Fudan University from January 2008 to December 2012. For asymptomatic aneurysms, repair criterion was a diameter over 3 cm while under 3 cm for symptomatic aneurysms.
