Is virtual reality useful for pain management in patients who undergo medical procedures?

Daniel Melecchi de Oliveira Freitas ORCID logo , Viviane Souto Spadoni ORCID logo

DOI: 10.31744/einstein_journal/2019MD4837

ABSTRACT Pain management is a complex medical issue, and many efforts have been done to develop new non-pharmacological therapies. Virtual reality is a technology apparatus that make an interaction between human and virtual environment through an hardware (usually a headset) linked to a computer or a mobile, by using a software. Additionally, this virtual setting can be adapted to any type of scenario. Thus, it is plausible that the software used should be personalized depending on patient’s experiences and expectations.

ABSTRACT Technical advances in magnetic resonance imaging have allowed to accurately detect and grade endolymphatic space distension in Ménière disease; this was only possible in post-mortem histological studies until a few years ago. Magnetic resonance imaging rules out other causes of vertigo and hearing loss, and is able to evaluate the cochlear and vestibular compartments of the endolymphatic space using a dedicated protocol.

Current state of multiparameter magnetic resonance imaging of the prostate

Thais Caldara Mussi

DOI: 10.1590/S1679-45082018MD4408

ABSTRACT Magnetic resonance imaging of the prostate is an imaging method that has shown increasing relevance in urological practice. Due to technological evolution of scanners and the introduction of functional sequences, it has enabled greater accuracy in detection and characterization of prostate tumors.

Functional magnetic resonance imaging for clinical evaluation of uterine contractility

Vinicius Adami Vayego Fornazari, Stela Adami Vayego, Denis Szejnfeld, Jacob Szejnfeld, Suzan Menasce Goldman

DOI: 10.1590/S1679-45082018MD3863

ABSTRACT Uterine contractility out of the gestational phase, during the menstrual cycle and the habitual functional variations of the organ, this is one of the responsible mechanisms for reproduction and fertility, due to its direct action in the mechanisms conducting the spermatozoa to the ovule and in the decidual implantation. Pathologies such as uterine leiomyoma, endometriosis, adenomyosis, polycystic ovarian syndrome, as well as the use of intrauterine devices and oral contraceptives, may alter a functionality of uterine contractility. Thus, magnetic […]

Munchausen syndrome and Munchausen syndrome by proxy: a narrative review

Daniel de Sousa Filho, Elton Yoji Kanomata, Ricardo Jonathan Feldman, Alfredo Maluf Neto

DOI: 10.1590/S1679-45082017MD3746

ABSTRACT The Munchausen syndrome and Munchausen syndrome by proxy are factitious disorders characterized by fabrication or induction of signs or symptoms of a disease, as well as alteration of laboratory tests. People with this syndrome pretend that they are sick and tend to seek treatment, without secondary gains, at different care facilities. Both syndromes are well-recognized conditions described in the literature since 1951. They are frequently observed by health teams in clinics, hospital wards and emergency rooms. We performed a […]

A new era of thromboelastometry

Tomaz Crochemore, Felipe Maia de Toledo Piza, Roseny dos Reis Rodrigues, João Carlos de Campos Guerra, Leonardo José Rolim Ferraz, Thiago Domingos Corrêa

ABSTRACT Severe hemorrhage with necessity of allogeneic blood transfusion is common complication in intensive care unit and is associated with increased morbidity and mortality. Prompt recognition and treatment of bleeding causes becomes essential for the effective control of hemorrhage, rationalizing the use of allogeneic blood components, and in this way, preventing an occurrence of their potential adverse effects. Conventional coagulation tests such as prothrombin time and activated partial thromboplastin time present limitations in predicting bleeding and guiding transfusion therapy in […]

The role of thromboelastometry in the assessment and treatment of coagulopathy in liver transplant patients

Raffael Pereira Cezar Zamper, Thiago Chaves Amorim, Luiz Guilherme Villares da Costa, Flávio Takaoka, Ary Serpa Neto

DOI: 10.1590/S1679-45082017MD3903

ABSTRACT Perioperative monitoring of coagulation is vital to assess bleeding risks, diagnose deficiencies associated with hemorrhage, and guide hemostatic therapy in major surgical procedures, such as liver transplantation. Routine static tests demand long turnaround time and do not assess platelet function; they are determined on plasma at a standard temperature of 37°C; hence these tests are ill-suited for intraoperative use. In contrast, methods which evaluate the viscoelastic properties of whole blood, such as thromboelastogram and rotational thromboelastometry, provide rapid qualitative […]

PET/MRI: a novel hybrid imaging technique. Major clinical indications and preliminary experience in Brazil

Taise Vitor, Karine Minaif Martins, Tudor Mihai Ionescu, Marcelo Livorsi da Cunha, Ronaldo Hueb Baroni, Marcio Ricardo Taveira Garcia, [...]

DOI: 10.1590/S1679-45082017MD3793

ABSTRACT In recent years, medical imaging with hybrid techniques has widely accepted and employed in clinical routine. PET/MRI offers significant advantages, including excellent contrast and resolution and reduced ionizing radiation, as compared to well-established PET/CT. Therefore, PET/MRI is a promising modality for oncologic imaging of some regions, such as brain, head and neck, liver and pelvis. This article set out to analyze clinical conditions that could benefit from PET/MRI imaging based on our caseload. The potential of PET/MRI to become […]

Sarcopenia and chemotherapy-mediated toxicity

Maria Cecília Monteiro Dela Vega, Alessandro Laviano, Gustavo Duarte Pimentel

DOI: 10.1590/s1679-45082016md3740

ABSTRACTThis narrative review focuses on the role of sarcopenia and chemotherapy-induced toxicity in cancer patients. Consistent evidence shows that sarcopenia in cancer patients leads to decreased overall survival by influencing treatment discontinuation and dose reduction. Therefore, sarcopenia should be considered a robust prognostic factor of negative outcome as well as a determinant of increased healthcare costs.

Intraoperative near-infrared fluorescent imaging during robotic operations

Antonio Luiz de Vasconcellos Macedo, Vladimir Schraibman

DOI: 10.1590/s1679-45082016md3658

ABSTRACTThe intraoperative identification of certain anatomical structures because they are small or visually occult may be challenging. The development of minimally invasive surgery brought additional difficulties to identify these structures due to the lack of complete tactile sensitivity. A number of different forms of intraoperative mapping have been tried. Recently, the near-infrared fluorescence imaging technology with indocyanine green has been added to robotic platforms. In addition, this technology has been tested in several types of operations, and has advantages such […]
