We report a family of glucocorticoid-remediable aldosteronism (GRA). A 20-year-old man presented with early-onset hypertension accompanied by hypokalemia was admitted to our hospital. Clinical data and family history were collected. Following genetic analyses with PCR and Sanger sequencing to document the chimeric gene and crossover site, respectively, we identified CYP11B1/CYP11B2 and determined the breakpoint of unequal crossover to be located in 264-380 nucletide, which was considered as GRA. There were 4 cases of GRA in the family, the average age of onset was 28 years, and all had different degrees of hypertension. Among them, the proband′s uncle suffered from moyamoya disease and died 6 months later due to sudden cerebral hemorrhage. In order to improve the understanding of this rare disease, the pathogenesis, biochemical profiles, diagnosis and treatment of GRA were summarized and analyzed.

Objective:To investigate the factors related to gastroesophageal reflux disease (GERD) in children.Methods:Clinical data of 370 children who underwent 24h multi-channel impedance-pH monitoring (24h MII-pH) in Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 2015 to December 2020 were enrolled in the study. The children were divided into GERD group ( n=202)and non-GERD group ( n=168) according to results of 24h MII-pH. The relationship of sex, age, body mass index (BMI), disease course, peripheral blood eosinophils count, IgE, Helicobacter pylori (Hp) infection, hiatus hernia of patients with GERD was analyzed by univariate and multivariate logistic regression analysis. Results:In GERD group 124 were males and 78 were females with a mean age of (6.4±4.1) years (2 months to 16.75 years), and in non-GERD group 82 were males and 86 were females with a mean age of (8.0±3.5) years (10 months to 15.17 years). Univariate logistic regression analysis showed that sex( OR=0.600,95% CI:0.396-0.908, P=0.016), age ( OR=0.537,95% CI:0.412-0.699, P<0.001)and hiatus hernia( OR=7.433,95% CI:2.567-21.520, P<0.001)were significantly associated with GERD of the children. Multivariate analysis showed that hiatus hernia ( OR=4.023,95% CI:1.298-12.470, P=0.016) was the independent risk factor, while male gender ( OR=0.567,95% CI:0.367-0.874, P=0.010) and younger age ( OR=0.613, 95%CI:0.459-0.819, P=0.001 ) were related factors of gastroesophageal reflux disease in children. Conclusion:Sex, age, and hiatal hernia are factors related to GERD in children.

A 43-year-old female patient was admitted with recurrent thrombosis for more than 2 years and thrombocytopenia for more than 1 year. Both arterial and venous thromboses developed especially at rare sites even during anticoagulation therapy such as cerebral venous sinus thrombosis. Antinuclear antibody, anti-ENA antibody and antiphospholipid antibody were all negative. Platelet count elevated to normal after high dose glucocorticoid and intravenous immunoglobulin (IVIG). Immune thrombocytopenia was suspected. When 4 grade thrombocytopenia recurred, intravenous heparin, rituximab 600 mg, IVIG and eltrombopag were administrated. After 3 weeks, thrombocytopenia did not improve, and new thrombosis developed instead. Screening of thrombophilia related genes revealed PROS1 gene heterozygous mutation and MTHFR TT genotype. Low amount of serum IgG κ monoclonal protein was detected. Heparin-induced thrombocytopenia was differentiated and excluded. Finally, serum negative antiphospholipid syndrome was considered the most likely diagnosis. Dexamethasone 20 mg/day × 4 days combined with sirolimus 2 mg/day was prescribed. The patient was discharged with low molecular weight heparin. At one month, her headache was greatly relieved. The platelet count raised to 20-30×10 9/L, and no new thrombosis or bleeding was reported.

Two cases of solitary fibrous tumor (SFT) with endocrine manifestations as the first symptom were investigated through comprehensively reviewing their medical history and clinical records. One case of recurrent giant solitary fibrous tumor of the thoracic cavity had repeated dizziness, palpitation and limb weakness for one month. The patient had hypoglycemia accompanied with significantly decreased serum insulin, and the ratio of insulin-like growth factor Ⅱ(IGF-Ⅱ) and insulin-like growth factor Ⅰ (IGF-Ⅰ) was greater than 10. Non-islet cell tumor hypoglycemia (NICTH) should be considered in the patient. Another case was found to have thyroid gland SFT and developed distant metastasis. The patient presented with hypoglycemia, hypokalemia and possible consumptive hypothyroidism. Clinicians should improve our understanding of the endocrine manifestations of the disease. SFT may occur in endocrine glands (such as thyroid), and may also present as NICTH and consumptive hypothyroidism.
