Dystrophic calcification of maxillary sinus in pediatric patients with liver transplantation and pigmentation of dental organ

RESUMO Objetivo: Relatar um caso de calcifica ção distrófica intensa no interior do seio maxilar em uma criança com transplante hepático e órgãos dentais pigmentados por hiperbilirrubinemia. Descrição do caso: Paciente do sexo feminino, 12 anos de idade, com transplante hepático efetuado aos 7 anos de vida devido à atresia de vias biliares extra-hepática, uso de tacrolimus imunossupressor (2 mg diários). No exame clínico intrabucal, observou-se a presença de pigmentação esverdeada no órgão dental por bilirrubina. Efetuou-se um exame de tomografia computadorizada volumétrica de feixe cônico para análise da densidade radiográfica dos elementos dentais pigmentados. Mediante interpretação da imagem pela escala de Hounsfield, não foi constatada nenhuma alteração na densidade radiográfica das estruturas do órgão dental. No entanto, a tomografia computadorizada evidenciou a presença de calcificação distr ófica intensa em região de seio maxilar. Comentários: A alteração de imagem observada no exame de tomografia computadorizada demonstrou achado radiográfico relevante, com presença de radiopacidades no interior do seio maxilar decorrentes de sinusites fúngicas ou não fúngicas. O rel...

CONCLUSIONS: This is the largest cohort reported in the literature of patients with frostbite injuries treated with HBOT. Hyperbaric oxygen therapy may show positive impact on the demarcation level of frostbite and, despite the common side effects, it generally causes no long-term sequelae.

ConclusionComputed tomography examinations are a more reliable method for differential diagnosis of thyroid nodules than ultrasound examinations followed by fine needle aspiration biopsy.Level of EvidenceIII.ResumoIntroduçãoA ultrassonografia é um método rápido para determinar de qual nódulo deve-se coletar uma amostra para biópsia por aspiração com agulha fina. Por outro lado, o exame de tomografia computadorizada não é restringido pela atenuação do eco e distingue entre nódulos benignos e malignos.ObjetivoComparar exames tom...

ConclusionsAn improvement in efficacy could not be observed after modified DHAP regimen; however, manageable toxicity and reduced renal complications suggest further investigation. The study, however, also underlines the need for new concepts in the management of advanced and high-risk lymphomas.

The as-prepared samples were heat-treated at different temperatures (300 °C - 500 °C) in air. Both as-deposited and heat-treated samples have a high porosity foam-like morphology, as shown by Field Emission Scanning Electron Microscopy. High Resolution Transmission Electron Mi...

In this study, a corrosion-resistant polymer coating with self-cleaning properties on Mg alloy AZ31 was successfully fabricated via a pretreatment of amino-silane (poly(3-aminopropyl)trimethoxysilane, PAPTMS) and subsequently covered with a polypropylene (PP) film. Surface morphology and chemical compositions were examined using field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and Fourier transform infrared spectrophotometry (FT-IR) and X-ray photoelectron spectroscopy (XPS) as well. Contact angle was measured to determine hydrophobicity of the composite coatings. Water permeability of the coa...

Debangshu Ghosh, Somnath Saha, Sumit Kumar BasuIndian Journal of Ophthalmology 2015 63(10):800-803Ectrodactyly-ectodermal dysplasia and clefting syndrome or "Lobster claw" deformity is a rare congenital anomaly that affects tissues of ectodermal and mesodermal origin. Nasolacrimal duct (NLD) obstruction with or without atresia of lacrimal passage is a common finding of such a syndrome. The authors report here even a rarer presentation of the syndrome which manifested as bilateral NLD obstruction and lacrimal fistula along with cleft lip and palate, syndactyly affecting all four limbs, mild mental retardation, oti...
