- Variations in peak expiratory flow measurements associated to air pollution and allergic sensitization in children in Sao Paulo, Brazil(2012) CORREIA-DEUR, Joya Emilie de M.; CLAUDIO, Luz; IMAZAWA, Alice Takimoto; ELUF-NETO, JoseBackground In the last 20 years, there has been an increase in the incidence of allergic respiratory diseases worldwide and exposure to air pollution has been discussed as one of the factors associated with this increase. The objective of this study was to investigate the effects of air pollution on peak expiratory flow (PEF) and FEV1 in children with and without allergic sensitization. Methods Ninety-six children were followed from April to July, 2004 with spirometry measurements. They were tested for allergic sensitization (IgE, skin prick test, eosinophilia) and asked about allergic symptoms. Air pollution, temperature, and relative humidity data were available. Results Decrements in PEF were observed with previous 24-hr average exposure to air pollution, as well as with 310-day average exposure and were associated mainly with PM10, NO2, and O3 in all three categories of allergic sensitization. Even though allergic sensitized children tended to present larger decrements in the PEF measurements they were not statistically different from the non-allergic sensitized. Decrements in FEV1 were observed mainly with previous 24-hr average exposure and 3-day moving average. Conclusions Decrements in PEF associated with air pollution were observed in children independent from their allergic sensitization status. Their daily exposure to air pollution can be responsible for a chronic inflammatory process that might impair their lung growth and later their lung function in adulthood. Am. J. Ind.

- New Insights Into Pheochromocytoma Surveillance of Young Patients With VHL Missense Mutations(2019) FAGUNDES, Gustavo F. C.; PETENUCI, Janaina; JR, Delmar M. Lourenco; TRARBACH, Ericka B.; PEREIRA, Maria Adelaide A.; D'EUR, Joya Emilie Correa; HOFF, Ana O.; LERARIO, Antonio M.; ZERBINI, Maria Claudia N.; SIQUEIRA, Sheila; YAMAUCHI, Fernando; SROUGI, Victor; TANNO, Fabio Y.; CHAMBO, Jose Luis; LATRONICO, Ana Claudia; MENDONCA, Berenice B.; V, Maria Candida B. Fragoso; ALMEIDA, Madson Q.Context: Von Hippel-Lindau (VHL) disease is an autosomal dominant syndrome caused by germline mutations in the VHL gene. Guidelines recommend pheochromocytoma (PHEO) biochemical screening should start at age 5 years. Objective: Genotype-phenotype correlations in VHL, focusing on PHEO penetrance in children, were studied. Design: We retrospectively evaluated 31 individuals (median age at diagnosis was 26 years) with diagnosed VHL disease. Results: PHEO was diagnosed in six children with VHL. A large PHEO (5 cm) was detected in a 4-yearold boy with p.Gly114Ser mutation. PHEO penetrance was 55% starting at age 4 years. VHL missense mutations were identified in 11 of 22 families (50%), frameshift mutations in four (18.2%), stop codon in three (13.6%), splicing site in two (9.1%), and large gene deletion in two (9.1%). The codon 167 (n = 10) was a hotspot for VHL mutations and was significantly associated with PHEO (90% vs. 38%; P = 0.007). PHEOs and pancreatic neuroendocrine tumors (PNETs) were strongly associated with VHL missense mutations compared with other mutations (89.5% vs. 0% and 73.7% vs. 16.7%; P = 0.0001 and 0.002, respectively). In contrast, pancreatic cysts (91.7% vs. 26.3%; P = 0.0001), renal cysts (66.7% vs. 26.3%; P = 0.027), and central nervous system hemangioblastomas (91.7% vs. 47.3%; P = 0.012) were more frequent in VHL with nonmissense mutations. Conclusion: VHL missense mutations were highly associated with PHEO and PNETs. Our data support that in children with VHL harboring missense mutations, biochemical screening for PHEO should be initiated at diagnosis.
- Targeted massively parallel sequencing for congenital generalized lipodystrophy(2020) COSTA-RIQUETTO, Aline D.; SANTANA, Lucas S.; CAETANO, Lilian A.; LERARIO, Antonio M.; CORREIA-DEUR, Joya E. M.; BERTOLA, Debora R.; KIM, Chong A.; NERY, Marcia; JORGE, Alexander A. L.; TELES, Milena G.Objective. Our aim is to establish genetic diagnosis of congenital generalized lipodystrophy (CGL) using targeted massively parallel sequencing (MPS), also known as next-generation sequencing (NGS). Subjects and methods: Nine unrelated individuals with a clinical diagnosis of CGL were recruited. We used a customized panel to capture genes related to genetic lipodystrophies. DNA libraries were generated, sequenced using the Illumina MiSeq, and bioinformatics analysis was performed. Results: An accurate genetic diagnosis was stated for all nine patients. Four had pathogenic variants in AGPAT2 and three in BSCL2. Three large homozygous deletions in AGPAT2 were identified by copy-number variant analysis. Conclusions: Although we have found allelic variants in only 2 genes related to CGL, the panel was able to identify different variants including deletions that would have been missed by Sanger sequencing. We believe that MPS is a valuable tool for the genetic diagnosis of multi-genes related diseases, including CGL.
