Virtual Reality as a distraction therapy during cystoscopy: a clinical trial.

OBJECTIVES: to investigate whether virtual reality (VR) experience is associated with decreased pain sensation among patients who undergo rigid cystoscopy under local anesthesia. METHODS: we performed a prospective, randomized, controlled study of 159 patients who were aleatorily enrolled into two groups: VR and control. VR experience intervention consisted of using a headset with a smartphone adapted to a virtual reality glasses where an app-video was played during the procedure. Main outcomes analyzed were pain, discomfort, heart rate variability, difficulty and duration of the cystoscopy. Statistical analyses were performed using a Student's t test, Mann-Whitney test and Chi-square test. A P<0.05 was considered to be statistically significant. RESULTS: among 159 patients studied (VR group=80 patients; control group=79 patients), the mean age was 63,6 years and 107 (67,3%) were male. There was no statistically significant difference in baseline characteristics between the 2 groups. VR was significantly associated to decreased heart rate variability (6,29 vs 11,09 bpm, P<0,001) and lower duration of the procedure (5,33 vs 8,65 min, P<0,001). Also, when cystoscopies due to double-J extraction were excluded, VR experience was associated with reduced pain on the visual analog score of pain (3,26 vs 4,33 cm, P=0,023). CONCLUSIONS: the use of VR as a distraction therapy while performing outpatient cystoscopies is safe, has no side effects, is associated with less pain and discomfort, and reduces length of procedure.

RESUMO Objetivos: investigar se a experiência de realidade virtual (RV) está associada à diminuição da dor em pacientes submetidos à cistoscopia rígida sob anestesia local. Métodos: foi realizado um estudo prospectivo, randomizado e controlado de 159 pacientes que foram alocados aleatoriamente em dois grupos: RV e controle. A intervenção da experiência de RV consistiu no uso de óculos de realidade virtual com smartphone adaptado e fones de ouvido, onde um vídeo foi reproduzido durante o procedimento. Os principais desfechos analisados foram dor, desconforto, variabilidade da frequência cardíaca, dificuldade e duração da cistoscopia. As análises estatísticas foram realizadas com o teste t de Student, o teste de Mann-Whitney e o teste do qui-quadrado. Um P<0,05 foi considerado como estatisticamente significativo. Resultados: entre os 159 pacientes estudados (grupo RV=80; grupo controle=79), a média de idade foi 63,6 anos e 107 (67,3%) eram do sexo masculino. Não houve diferença estatisticamente significativa nas características basais entre os grupos. A RV foi significativamente associada à menor variabilidade da frequência cardíaca (6,29 vs 11,09 bpm, P<0,001) e menor duração do procedimento (5,33 vs 8,65 min, P<0,001). Além disso, quando cistoscopias devido à extração de duplo J foram excluídas, a RV foi associada à redução da dor na escala visual analógica (3,26 vs 4,33cm, P=0,023). Conclusões: o uso da RV como terapia de distração durante a realização de cistoscopias ambulatoriais é seguro, não tem efeitos colaterais, está associado a menos dor e desconforto e reduz a duração do procedimento.

Fosfomycin trometamol vs ciprofloxacin for antibiotic prophylaxis before transrectal ultrasonography-guided prostate biopsy: A meta-analysis of clinical studies.

Objectives: To perform a systematic review and meta-analysis of clinical studies to assess the comparative prophylactic effectiveness of fosfomycin trometamol (FMT) vs ciprofloxacin (CIP) in men who underwent transrectal ultrasonography-guided prostate needle biopsy (TRUS-PNB), as infectious complications are a major concern after TRUS-PNB and although fluoroquinolones are currently the first choice, an increase in resistance has raised the question about its recommendation and FMT is a broad-spectrum oral antibiotic with low bacterial resistance. Methods: A systematic review was performed between January 1970 and June 2017 using the Web of Science, Scopus and PubMed databases to identify relevant studies. Preferred Reporting Items for Systematic Reviews and Meta-analysis criteria were used for article selection. Outcomes of interest were febrile and afebrile urinary tract infections (UTIs) and the presence of fluoroquinolone-resisitant (FQR)- or extended-spectrum ß-lactamase (ESBL)-producing uropathogens in urinary cultures. Results: Four studies including 2331 men were analysed; 1088 had FMT and 1243 CIP as antibiotic prophylaxis before TRUS-PNB. FMT prophylaxis resulted in significantly less afebrile (odds ratio [OR] 0.21, 95% confidence interval [CI] 0.12-0.38; P < 0.001) and febrile (OR 0.15, 95% CI 0.07-0.31; P < 0.001) UTIs than CIP. Amongst all urine cultures, patients in the FMT arm also had a significantly lower prevalence of FQR and ESBL (E. coli or K. pneumoniae) microorganisms when compared to the CIP group (OR 0.25, 95% CI 0.12-0.21, P = 0.001; and OR 0.24, 95% CI 0.10-0.58, P = 0.001, respectively). Conclusions: Antibiotic prophylaxis with FMT before TRUS-PNB was associated with lower rates of infectious complications when compared to CIP. Abbreviations: CIP: ciprofloxacin; ESBL: extended-spectrum ß-lactamase; FMT: fosfomycin trometamol; FQR: fluoroquinolone-resisitant; OR: odds ratio; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; TRUS-PNB: TRUS-guided prostate needle biopsy.

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

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. The use of virtual reality as a medical tool for pain relief or decrease analgesics use by promoting a cognitive distraction is a low cost and promising instrument for pain management in patients who undergo medical procedures.

RESUMO O manejo da dor é uma questão médica complexa, e muitos esforços têm sido feito para que novas terapias não farmacológicas sejam desenvolvidas. A realidade virtual é um aparato tecnológico que promove interação entre humanos e ambiente virtual, por meio de hardware (geralmente fones de ouvido), conectado a computador ou celular, e de software. Além disso, este ambiente virtual pode ser adaptado para qualquer tipo de cenário. Portanto, é plausível que o software utilizado seja personalizado, dependendo da experiência do paciente e de suas expectativas. O uso da realidade virtual como ferramenta médica para alívio da dor ou redução do uso de analgésicos, por meio de distração cognitiva, é um instrumento promissor e de baixo custo para manejo da dor em indivíduos submetidos a procedimentos médicos.

Cirurgia videolaparoscópica nas doenças biliopancreáticas / Laparoscopic surgery in pancreatobiliary diseases

Com a experiência adquirida na cirurgia da vesícula biliar, a videocirurgia está sendo indicada cada vez mais em outras doenças. Decorridos 15 anos da primeira cirurgia, os autores avaliam os resultados e analisam as perspectivas deste procedimento nas doenças biliopancreáticas. Seguem a proposta que divide este procedimento em procedimentos de rotina, avaliação e desenvolvimento. Nas doenças da vesícula biliar, a colecistectomia laparoscópica é considerada padrão ouro, levando vantagem em todos os itens sobre a laparotômica, excluídas as lesões da via biliar e o vazamento biliar pelo coto cístico. Enfatizam situaçõesespeciais: da colecistite aguda, da colecistectomia durante a gravidez, da vesícula em porcelana e do câncerda vesícula. Comentam as perspectivas da videocirurgia nas complicações da colecistectomia laparoscópica. No tratamento da coledocolitíase, consideram o procedimento como em avaliação pela falta de ensaios clínicos prospectivos randomizados com grupo controle comparáveis e acompanhados por prazo de tempo maior. Nas doenças do pâncreas, a videocirurgia é um procedimento em desenvolvimento, com exceção da pancreatite aguda biliar não complicada, que se beneficia com a colecistectomia laparoscópica. O mesmoocorre com as cirurgias de derivação para desobstrução da via biliar. Embora factíveis dentro dos princípios da cirurgia convencional, faltam estudos comparativos com outras técnicas existentes analisando eficácia e efetividade.

With the acquired experience with laparoscopic cholecystectomy, videosurgery has been used more andmore for treatment of other diseases. Since the first surgery, nearly 15 years ago, the authors evaluate the outcome and the perspectives of this procedure in pancreatic-billiary diseases. They followed the proposition which divides these procedures in routine procedures, in evaluation and in development. In gallbladder diseases the laparoscopic cholecystectomy is considered gold-standard, taking advantage upon opencholecystectomy, excluding bile duct injury and cystic stump leakage. They emphasize the aspects related to acute cholecystitis, cholecystectomy during pregnancy, calcified gallbladder and cancer. The laparoscopic cholecystectomy during pregnancy is considered as a procedure in evaluation. Long term effects of pneumoperitonium on foetus are not well known. The approach in calcified gallbladder, because the high incidence of adenocarcinoma, remains questionable. Perspectives of videosurgery in complications of laparoscopic cholecystectomy are commented. Cystic stump leakage, misplaced clips and partial section or laceration of main biliary tract could be treated by new videosurgery in selected situations. In the treatment of choledocolithiasis, they consider the procedure as one for evaluation, due to the lack ofrandomized prospective trials. Until now, videocholedocolitotomy is reserved to specialized centers. Inpancreatic diseases, videosurgery is a procedure in development, except for the non-complicated acute biliary pancreatitis, in which benefits with laparoscopic cholecystectomy has been shown. The same occurs with diversion surgeries for desobstruction of the biliary tree. Although performed within the conventional surgery principles there is a lack of comparative studies with other techniques analysingefficacy and efficiency.

Fisiopatologia, diagnóstico e tratamento da menorragia na adolescência / Menorrhagia in adolescence: phisiopathology, diagnosis and treatment

A menorragia é um problema ginecológico comum em adolescentes. Os dois primeiros anos pós-menarca geralmente säo anovulatórios e a maioria dos casos de sangramento excessiva resulta da imaturidade do eixo hipotálamo-hipófise-ovário. Entretanto, o diagnóstico diferencial deve incluir coagulopatias, tireoidopatias e Síndrome de Ovários Policísticos, entre outros. A fisiopatologia do sangramento excessivo ainda näo está bem definida mas acredita-se que alteraçöes hemostáticas e hormonais estejam envolvidas. Para o diagnóstico da etiologia da menorragia, a história menstrual e a idade ginecológica (tempo decorrido desde a menarca) säo fundamentais. Um hemograma e uma ecografia transvaginal podem auxiliar bastante. O tratamento pode variar desde a tranqüilizaçäo e acompanhamento da adolescente, até a terapia medicamentosa agressiva. O tratamento cirúrgico é incomum

Alterações neurológicas em pacientes submetidos a transplante hepático: análise de 30 casos consecutivos / Neurologic alterations in patients submitted to liver transplantation: analysis of 30 consecutive cases

As complicações neurológicas em transplante hepático (TxH) são importante causa de morbi-mortalidade, pois as intercorrências podem resultar de fatores prévios ao TxH, de alterações trans-operatórias, de dificuldades com os imunossupressores, coagulopatias e infecções do período pós-operatório. Nós analisamos , retrospectivamente, a cronologia, as causas e as frequências das alterações neurológicas de 30 pacientes adultos submetidos a TxH e constatamos que nossos resultados diferem ligeiramente dos apresentados em outras séries.
