Case Reports
Epidermolysis bullosa acquisita as an adverse effect from rituximab therapy: A case report.
Rituximab is a monoclonal antibody directed against B cells and is a first-line agent for the treatment of B cell lymphoma and a second-line agent for the treatment of idiopathic thrombocytopenic purpura (ITP). It has also been used for the treatment of several other autoimmune diseases. Epidermolysis bullosa acquisita (EBA) has never been reported as an adverse effect resulted from rituximab therapy. ⋯ Physicians should consider this diagnosis when a patient develops bullous skin eruptions while undergoing Rituximab therapy.

Neuroendocrine carcinoma of the nasal cavity with epiphora as the first symptom: A case report.
Neuroendocrine carcinomas (NECs) are rare malignancies that originate from the hormone-producing cells of the neuroendocrine system. They can grow in most organs of the body but are commonly found in the gastrointestinal and respiratory tracts. The nasal cavity is a rare site for NECs. ⋯ Diagnosing nasal neuroendocrine carcinoma is clinically challenging. It must be distinguished from other orbital masses, such as chronic dacryocystitis or nasal polyps. The treatment should be further investigated for this rare malignancy in near future.

Targeting protein for Xenopus kinesin-like protein 2 (TPX2) has been identified as an oncogene in multiple cancers. However, the associations among TPX2 expression, prognosis, and tumor immunity in hepatic cell cancer (HCC) have not been explored. We analyzed TPX2 expression by multiple gene expression databases, including Oncomine, TIMER, and UALCAN. ⋯ In addition, TPX2 expression has a positive association with the infiltration of immune cells and the expression of immune checkpoint molecules. Coexpressed genes and functional network analysis suggested several potential mechanisms of TPX2 affecting HCC progression. The findings reveal that TPX2 has associations with prognosis and infiltration of immune cells in HCC patients, which has laid a basis for in-depth study of TPX2 role in HCC.

Preoperative sonographic diagnosis of McSwain type V appendiceal intussusception: A case report (with video).
Appendiceal intussusception is a rare disease. The definite preoperative diagnosis of appendiceal intussusception is rare and challenging. Here, we present a case of McSwain type V appendiceal intussusception in a 10-year-old boy. To our best knowledge, this is the first case report of a type V appendiceal intussusception that was preoperatively confirmed with sonography. Here, we have described in detail the ultrasound features and differential diagnosis of this rare disease. ⋯ Pre-operatively, on ultrasound a type V appendiceal intussusception is usually misdiagnosed as an ileocolic intussusception. Radiologists must execute caution to avoid over reliance on the sonographic findings of intussusception, especially when there is a mismatch with clinical symptoms. It is especially important to accurately understand the surgical-anatomic configuration of type V appendiceal intussusception that creates a "target-sign" and a "finger-like" layout on ultrasonography.

Observational Study
Congenital diaphragmatic hernias: Severe defect grade predicts the need for fundoplication.
Over one-third of infants with congenital diaphragmatic hernia (CDH) eventually require a Nissen fundoplication (NF). We examined pre- and intraoperative predictors for need of a NF in children undergoing CDH repair to elucidate, which patients will need a later NF. A retrospective analysis of all consecutive patients undergoing CDH repair at our institution from 2008 to 2018 was performed. ⋯ Absence of >50% of the hemidiaphragm was more frequent in the NF group (76% vs 31%, P < .001). Severe Defect Grade emerged as independent predictor for NF (odds ratio 7, 95% confidence interval 3-16, P < .001). Severe Defect Grade emerged as independent predictor for NF after CDH repair.
