Proteus syndrome (PS) is a complex disorder characterized by variable clinical findings of overgrowth and tumor susceptibility. This report presents the first known association between PS and an ovarian germ cell tumor in an adolescent with immature teratoma. A review of the diagnosis of PS and associated tumors is included.

BACKGROUND Coronavirus disease (COVID-19) is a budding infectious disease that has affected various countries globally. OBJECTIVE The aim of this study was to analyze the effect of COVID-19 disease on liver and kidney functions and to determine their association with the severity and mortality of disease METHODS A total of 100 confirmed COVID-19 adult patients from Madinah city of Saudi Arabia hospitalized between April 28, and June 30, 2020 were included,and categorized into asymptomatic,mild to moderate and severely ill patients.We analyzed the clinical status of liver and renal functioning in all of the three groups. RESULTS The majority of patients (51%) were diagnosed with mild to moderate disease, 27% of patients were severely ill and 22% of patients were asymptomatic.The liver and renal functional analysis showed that the severity of the COVID-19 patients were significantly associated with the kidney and renal impairments exhibiting higher levels of ALT, AST, Creatinine, Urea levels (P < 0.05). Furthermore, in this study, a novel association is found between high Na and Cl levels with the severely ill COVID-19 patients. CONCLUSIONS We concluded from the present study that a significant percentage of COVID-19 patients continued to have a normal liver and renal function during the course of their disease. Nevertheless, severely ill COVID-19 patients were more prone to have abnormal liver and renal functions. During the course of treatment, the patients had a gradual normalization of their liver and kidney parameters and subsequently achieved a complete normal liver and renal functions upon discharge with no mortality.

Reticulocalbin 1 (RCN1) is an endoplasmic reticulum (ER)-residing protein, involved in promoting cell survival during pathophysiological conditions that lead to ER stress. However, the key upstream receptor tyrosine kinase that regulates RCN1 expression and its potential role in cell survival in the glioblastoma setting have not been determined. Here, we demonstrate that RCN1 expression significantly correlates with poor glioblastoma patient survival. We also demonstrate that glioblastoma cells with expression of EGFRvIII receptor also have high RCN1 expression. Over-expression of wildtype EGFR also correlated with high RCN1 expression, suggesting that EGFR and EGFRvIII regulate RCN1 expression. Importantly, cells that expressed EGFRvIII and subsequently showed high RCN1 expression displayed greater cell viability under ER stress compared to EGFRvIII negative glioblastoma cells. Consistently, we also demonstrated that RCN1 knockdown reduced cell viability and exogenous introduction of RCN1 enhanced cell viability following induction of ER stress. Mechanistically, we demonstrate that the EGFRvIII-RCN1-driven increase in cell survival is due to the inactivation of the ER stress markers ATF4 and ATF6, maintained expression of the anti-apoptotic protein Bcl-2 and reduced activity of caspase 3/7. Our current findings identify that EGFRvIII regulates RCN1 expression and that this novel association promotes cell survival in glioblastoma cells during ER stress.
