Teflon Granuloma With Active Inflammation: A Cause of Recurrent Trigeminal Neuralgia After Microvascular Decompression: Imaging and Pathological Correlation.

Trigeminal neuralgia (TN) is characterized by excruciating facial pain usually caused by neurovascular compression of the trigeminal nerve roots. TN can be treated medically or invasively. Microvascular decompression is the procedure of choice and usually results in complete symptom relief.

Microcephaly in South Brazil: Are cases of Congenital Zika Syndrome increasing in recent years?

Northeast Brazil was the first region to detect a significant increase in babies born with microcephaly associated with prenatal zika virus infection in 2015. Rio Grande do Sul (RS) state was less impacted due to the temperate climate preventing the spread of the vector. This study investigated the prevalence and etiology of congenital microcephaly in RS in two different periods.

Therapy for mucopolysaccharidosis VI: (Maroteaux-Lamy syndrome) present status and prospects.

Mucopolysaccharidosis VI (MPS VI) is a lysosomal storage disorder caused by deficient activity of Arylsulphatase B (ARSB). The disease is progressive and multisystemic, usually leading to death in the first decades of life. In addition to supportive management, specific treatments for MPS VI are the hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT).

Treatment of malignant tracheoesophageal fistula.

This article addresses the treatment of malignant enterorespiratory fistulas, especially malignant tracheoesophageal fistula (mTEF). mTEF typically occurs after radiochemotherapy for advanced esophageal cancer. Life expectancy is measured in months after successful treatment, and in days to weeks with a persistent fistula.

A force plate based method for the calibration of force/torque sensors.

This study describes a novel calibration method for six-degrees-of-freedom force/torque sensors (FTsensors) using a pre-calibrated force plate (FP) as a reference measuring device. In this calibration method, the FTsensor is rigidly connected to a FP and force/torque data are synchronously recorded while a dynamic functional loading procedure is applied by the researcher. Based on these data an accurate calibration matrix for the FTsensor can easily be obtained via least-squares optimization.

Recent Advances in Treatment Approaches of Mucopolysaccharidosis VI.

Mucopolysaccharidosis VI is caused by accumulation of the glycosaminoglycan dermatan sulfate in all tissues due to decreased activity of the enzyme arylsulfatase B. Patients exhibit multisystemic signs and symptoms in a chronic and progressive manner, especially with changes in the skeleton, cardiopulmonary system, cornea, skin, liver, spleen and meninges. Patients usually have normal intelligence.

DNA damage in leukocytes from pretreatment mucopolysaccharidosis type II patients; protective effect of enzyme replacement therapy.

Mucopolysaccharidosis type II (MPS II) is an X-linked recessive disease caused by deficiency of the lysosomal enzyme iduronate-2-sulfatase, leading to progressive accumulation of glycosaminoglycans in nearly all cell types, tissues and organs. Enzyme replacement therapy reduces the storage of these substances in the lysosomes. Oxidative stress is related to the pathophysiology of many disorders, including inborn errors of metabolism.

Mutations in the amino-terminal region of proopiomelanocortin (POMC) in patients with early-onset obesity impair POMC sorting to the regulated secretory pathway.

Context: Mutations in the proopiomelanocortin (POMC) gene that impair the synthesis or structure of POMC-derived peptides predispose to human obesity.

Objective: Our objective was to identify and characterize novel mutations in the POMC gene found in patients with early-onset obesity.

Design And Patients: The POMC gene was screened in 500 patients with severe early-onset obesity.

CT-guided vertebroplasty: analysis of technical results, extraosseous cement leakages, and complications in 500 procedures.

The aim of this study was to analyze the technical results, the extraosseous cement leakages, and the complications in our first 500 vertebroplasty procedures. Patients with osteoporotic vertebral compression fractures or osteolytic lesions caused by malignant tumors were treated with CT-guided vertebroplasty. The technical results were documented with CT, and the extraosseous cement leakages and periinterventional clinical complications were analyzed as well as secondary fractures during follow-up.

[Looking for colorectal cancer in the patients iris?].

Background: Iridology is a noninvasive method from the field of complementary medicine that is said to detect diseases by looking for abnormalities of pigmentation and structure in the iris. Colorectal cancer is an ideal opportunity for screening programs because of its long period of development. Our study investigated the applicability of iridology as an alternative screening method for colorectal cancer.
