The finding of gas within the gastric wall is not a disease by itself, rather than a sign of an underlying condition which could be systemic or gastric. We present the case of a woman identified with gastric emphysema secondary to the administration of high doses of steroids, with the purpose of differentiating emphysematous gastritis versus gastric emphysema due to the divergent prognostic implications. Gastric emphysema entails a more benign course, opposed to emphysematous gastritis which often presents as an acute abdomen and carries a worse prognosis. Owing to the lack of established diagnostic criteria, computed tomography is the assessment method of choice. Currently no guidelines are available for the management of this entity, since the evidence is limited to a few case series and a considerable number of single case reports.
Our results confirm the importance of considering the duration of breast-feeding as an important risk factor for osteopenia/osteoporosis. In addition, we find that body mass index is positively associated with BMD. Because of the heterogeneity of the Mexican mestizo population, the risk factor for osteoporosis may not be the same in different ethnic groups.
Eosinophilic
gastroenteritis is considered an uncommon
disease with a low incidence rate that remains
as a diagnostic challenge for the clinician, in
spite of the fact that seventy years have passed
since its original description. Hereby we
present the case of a 29-year-old male without
history of allergies who was evaluated for
unspecific gastrointestinal symptoms, without
relevant findings on physical examination and
presenting an initial complete blood count (CBC)
with severe eosinophilia. The patient was
evaluated and the diagnosis of eosinophilic
gastroenteritis was confirmed by
histopathological findings. The relevance of the
case resides in highlighting the lack of
guidelines or consensus for histological
diagnosis being virtually the only one
available. To a similar extent, treatment
evidence is based on case series with a
reasonable number of patients and case
reports.
Osteoporosis is characterized by low bone mineral density (BMD). One of the most important factors that influence BMD is the genetic contribution. The collagen type 1 alpha 1 (COL1A1) and the JAGGED (JAG1) have been investigated in relation to BMD. The aim of this study was to investigate the possible association between two single-nucleotide polymorphisms (SNPs) of COL1A1, their haplotypes, and one SNP of JAG1 with BMD in postmenopausal Mexican-Mestizo women. Seven hundred and fifty unrelated postmenopausal women were included. Risk factors were recorded and BMD was measured in lumbar spine, total hip, and femoral neck by dual-energy X-ray absorptiometry. DNA was obtained from blood leukocytes. Two SNPs in COL1A1 (rs1800012 and rs1107946) and one in JAG1 (rs2273061) were studied. Real-time PCR allelic discrimination was used for genotyping. The differences between the means of the BMDs according to genotype were analyzed with covariance. Deviations from Hardy-Weinberg equilibrium were AGE (2013) , and haplotype analysis of COL1A1 was conducted. Under a dominant model, the rs1800012 polymorphism of the COL1A1 showed an association with BMD of the lumbar spine (P00.021). In addition, analysis of the haplotype of COL1A1 showed that the G-G haplotype presented a higher BMD in lumbar spine. We did not find an association between the s1107946 and rs2273061 polymorphisms of the COL1A1 and JAG1, respectively. Our results suggest that the rs1800012 polymorphism of the COL1A1, in addition to one haplotype, were significantly associated with BMD variation in Mexican-Mestizo postmenopausal women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
