Serum iron and vitamin B 12 deficiency could indicate celiac disease by flexible spectral imaging color enhancement.
INTRODUCTION Celiac disease (CeD) is an autoimmune disease that can be delayed in diagnosis due to the presence of atypical and asymptomatic cases in adulthood. Herein we aimed to study the frequency of CeD and evaluate whether magnified endoscopy and magnified/FICE (flexible spectral imaging color enhancement) techniques contribute to the diagnosis in patients with serum iron and vitamin B12 deficiency. METHODS We evaluated 50 adult patients (10 males and 40 females) who had serum iron and vitamin B12 deficiency, prospectively. ⋯ Six of 10 patients (60%) who were diagnosed as CeD had typical endoscopic images under white lighted endoscopy. All of these 10 patients (100%) showed villous irregularity, partial villous atrophy, or total villous atrophy consistent with CeD with magnified and magnified/FICE endoscopy. CONCLUSION The practical use of magnified/FICE endoscopy allows us to differentiate mucosal abnormalities of the duodenum and minimize false-negative results that indicate normal mucosal findings with conventional endoscopy.

Lattice radiation therapy - its concept and impact in the immunomodulation cancer treatment era.
Voluminous tumors represent a challenge in radiation oncology, particularly when surgical resection is not possible. Lattice radiotherapy (LTR) is a technique that may provide equivalent or superior clinical response in the management of large tumors while limiting toxicity to adjacent normal tissues. LRT can precisely deliver inhomogeneous high doses of radiation to different areas within the gross tumor volumes (GTV). ⋯ LRT delivers high doses of radiation without exceeding the tolerance of adjacent critical structures. Radiobiological experiments support the role of radiation-induced bystander effects, vascular alterations, and immunologic interactions in areas subject to low dose radiation. The technological advancements continue to expand in Radiation Oncology, bringing new safety opportunities of treatment for bulky lesions.

Physical and financial participation of teaching hospitals in private care in São Paulo - Brasil.
OBJECTIVE To evaluate the physical and financial participation of private health insurance beneficiaries in the TH located in the State of Sao Paulo, regarding the care of Brazilian Unique Health System patients, in the year 2017. METHODS The research data were obtained from the System of Evaluation of the Teaching Hospitals (SAHE), of the State Department of Health of São Paulo (SES/SP). RESULTS It was observed that, on average, the TH analyzed provide 17% of their operational vacancies for the Supplementary Health System, and that the financial return is better in the philanthropic ones. CONCLUSIONS The health care services provided by TH deserve to be deepened, evaluating the real advantages obtained in the provision of services, given that supplementary health care requires differentiated infrastructure, and mainly the knowledge of operational costs in order to stipulate the procedures' price.
