RESUMO Objetivo: relatar a experiência inicial com a terapia por pressão negativa por instilação em feridas complexas infectadas ou contaminadas. Métodos: a terapia por pressão negativa por instilação utilizada foi o V.A.C. Ulta com instilação Veraflo (Kinetic Concepts, Inc). O modo de operação foi contínuo com pressão sub-atmosférica ajustada em 125 mmHg por duas horas e instilação entre as pausas. O tempo de instilação foi de 20 minutos (tempo de contato do agente tópico com a ferida) e a substância instilada foi solução salina padrão a 0,9%. Após obtenção de preparo adequado da ferida, ela foi coberta com enxerto ou retalho. Resultados: foram operados dez pacientes com feridas complexas contaminadas ou infectadas. O número médio de trocas da TPNi foi 1,4, o número médio total de cirurgias foi de 2,4, o intervalo até a cobertura da ferida foi de 6,3 dias e o intervalo até a alta foi de 11,4 dias. Conclusão: a comparação da terapia por pressão negativa por instilação com dois estudos prévios (controle histórico) evidenciou um tempo de internação menor, favorecendo a TPNi. Este estudo teve um caráter inicial, fazendo-se necessário conduzir um trabalho randomizado e controlado para confirmar a eficácia desta terapia e verificar a sua custo-efetividade.

Struma ovarii is an uncommon condition, in which thyroid tissue is the predominant or exclusive element in an ovarian teratoma. Thyroid tissue may demonstrate the same spectrum of pathological features as in the normal thyroid including benign and malignant changes. We present a case of papillary thyroid carcinoma arising in a struma ovarii of the left ovary in a 21-year-old female.

Tunica albuginea (TA) cyst is the most common extratesticular benign mass, which is usually palpable. Ultrasound examination is the imaging modality of choice to characterize palpable testicular lesions. This pictorial essay presents the spectrum of sonographic features of TA cysts in order to assist radiologists in making the correct diagnosis and avoid unnecessary surgeries.

The aim of this study was to ascertain the frequency of use, search intent (SI), level of accessibility, and degree of reliability of sources of information (SOIs) in rheumatology. Methods:A survey among adult outpatients with rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, and spondyloarthritis was conducted. They were asked if they had procured information from 12 selected SOIs during the past year. Search intent was defined as the source they would like to consult. Accessibility and reliability were assessed through 0-to-10 scales (minimum and maximum, respectively).Results: Four hundred two patients were surveyed. They had consulted a median of 3 SOIs (interquartile range, 2-6) but described a higher SI: median of 5 SOIs (interquartile range 3-8); p = 0.001.The most consulted SOIs were the physician (83%), other patients (45%), and Facebook (36%). The main differences between SI and the searches actually performed were observed in community lectures by health care professionals (49%), scientific societies (48%), and associations of patients (27%); p < 0.001. These 3 sources showed low level of accessibility. Facebook, press, radio, and YouTube were the least reliable sources.Conclusions: Patients consulted a median of 3 SOIs but reported a significantly higher SI. Although patients demand more information, the request is leveled at SOIs with difficult accessibility but high reliability.

Objective To assess key aspects of transportation and storage of biological therapies (BTs) on the part of the patients, from the time they collect them from the pharmacy up until the moment of administration. Methods This was a cross-sectional study in the form of a survey completed by outpatients older than 18 years who were administered BTs. The survey was carried out by the authors between August 2016 and January 2017. Results A total of 83 outpatients were interviewed (mean age, 53; standard deviation, 15; 76% female). Sixty percent had rheumatoid arthritis, 24% had psoriatic arthritis, and 16% sustained other rheumatic and inflammatory diseases. Twenty percent had not been informed of the importance of proper refrigeration when they were first prescribed BTs; 77% had acquired the medication at least 7 days before administration; 28% had misplaced the drug in the fridge (65% of them in the freezer); 90% was unaware of the temperature range at which the BT should be kept in the fridge, and only one (1%) of them had once used a thermometer to find out the fridge temperature. Fifty-three percent had suffered frequent power outages the previous summer, 22% had experienced blackouts longer than 48 hours; 37% had taken the BT to another house to avoid wasting it, and four (5%) patients had disposed of the drug due to a prolonged power outage. Conclusion Upon prescribing BTs, it is imperative that physicians brief patients on the relevance of suitable transportation and storage methods, and a treatment failure should prompt a thorough assessment of transportation and storage conditions.
