COVID-19-Related Intestinal Ischemia in A 7-Year Old Boy.

Severe abdominal pain and vomiting are common symptoms in children with pediatric multisystem inflammatory syndrome (PIMS). Mesenteric lymphadenitis and aseptic peritonitis are predominantly reported in cases where acute surgical abdomen was suspected and laparotomy was performed at the early stage of the pandemic. These reports generally discouraged surgeons to perform exploration in COVID-19-related cases and medical management was prioritized.

X-ray physics-based CT-to-composition conversion applied to a tissue engineering scaffold, enabling multiscale simulation of its elastic behavior.

Nowadays, the assessment of the mechanical competence of tissue engineering scaffolds based on computer simulations is a well-accepted technology. Typically, such simulations are performed by means of the Finite Element (FE) method, with the underlying structural model being created based on micro-computed tomography (microCT). Here, this analysis modality is applied to a new, ternary composite, consisting of PHBV, i.

The First Reported Case of Trichothiodystrophy in Hungary: A Young Male Patient with Mutations in the ERCC2 Gene.

Trichothiodystrophy, also called sulphur-deficient brittle hair syndrome, is a rare autosomal recessive genetic disorder of DNA repair and transcription. Trichothiodysthrophy is characterised by dry, thin, easily broken hair, showing alternating light and dark pattern called 'tiger tail' banding under polarizing light microscopy. According to our knowledge, our report is the first one on this rare disorder from Hungary: a case of a 9-year-old boy showing clinical features typical of trichotiodystrophy.
