Trichohepatoenteric syndrome and cytomegalovirus infection: Case report and literature summary.

Trichohepatoenteric syndrome is a rare autosomal recessive genetic disease caused by TTC37 (also known as SKIC3) or SKIV2L gene variant. We present a severely affected 2-month-old male infant with recurrent fever and unexplained diarrhea. Additionally, clinical data of 11 patients with trichohepatoenteric syndrome in China from 1 to 60 days of onset was presented. The infant's condition was not substantially relieved after cefotaxime sulbactam and meropenem treatment. Whole-exome sequencing revealed compound heterozygous variants (c.1708C>T and c.3342-9T>G) in TTC37 of the child whose parents were heterozygous carriers of the corresponding locus. The c.3342-9T>G variant originated from his mother and was reported for the first time. Combined with the clinical manifestations, the infant was diagnosed with trichohepatoenteric syndrome and treated with ganciclovir antiviral, intravenous nutritional support, and liver function protection. The infant was discharged with no fever and high stool frequency, but his condition improved. Therefore, trichohepatoenteric syndrome should be considered for recurrent fever and unexplained diarrhea.

Distal end of a ureteral double-J stent displaced into the contralateral ureter after percutaneous nephrolithotripsy: a case report.

We report displacement of the distal end of a ureteral double-J stent into the contralateral ureter after percutaneous nephrolithotripsy (PCNL) in a 71-year-old man with a history of left kidney stones. Postoperative computed tomography imaging showed that the distal end of the left ureteral double-J stent was displaced into the right ureter, which resulted in persistent right renal colic when the nephrostomy tube was clipped and continuous urine leakage from the nephrostomy opening after the nephrostomy tube was removed. After the cystoscopic adjustment of the ureteral stent, the patient recovered uneventfully and was discharged home the next day.

Effects of mixed carriers on diatomite supported nano-TiO2.

In this study, calcium carbonate, sepiolite, and commonly used diatomite (DE) carriers were mixed to prepare calcium carbonate or sepiolite mixed DE/nano-titanium dioxide (TiO2). The analyses of X-ray diffraction and scanning electron microscope confirmed that the particle size of nano-TiO2 was about 20-24 nm in DE/nano-TiO2, and the particles were relatively uniform. When (calcium carbonate and sepiolite + DE)/nano-TiO2 was used, the Ti content in the composite remained unchanged, while the particle size of nano-TiO2 increased to a certain extent. Among them, the use of (calcium carbonate + DE)/nano-TiO2 increased the Ti content in the composite material significantly. Therefore, the findings demonstrated the feasibility of nano-TiO2 supported by the mixed carrier.
