Lidocaine-prilocaine cream as analgesia for hysterosalpingography: a randomized, double blinded, controlled study.

OBJECTIVE: The efficacy of lidocaine-prilocaine cream (EMLA(®)) analgesia in the practice of hysterosalpingography is controversial. This study provides new drill results and a new method of application in terms of mode, time and place. The aim of the paper is to investigate the efficacy of 5% lidocaine 25 mg-prilocaine 25 mg/g cream applied to the uterine cervix for reducing pain during hysterosalpingography. STUDY DESIGN: A randomized, double blinded, controlled study set in the general gynaecology clinic of a university teaching hospital between September 2012 and June 2013. One hundred successive patients programmed to undergo hysterosalpingography were randomized to either 3 ml of EMLA (50) cream or 3 ml of placebo (50), placed endocervically and exocervically, 10 min before hysterosalpingography. Patients' intensity of pain was assessed in four steps: at baseline (speculum application), after application of Pozzi tenaculum and cannula on the uterine cervix, during cervical traction and after contrast medium injection, using a 10-cm Visual Analogue Scale (VAS) immediately after the procedure. The most painful step was also identified. VAS was administered again at one-month follow-up visit. TRIAL REGISTRATION: NCT01303614. RESULTS: The contrast medium injection was the most painful step of hysterosalpingography in both groups (EMLA 3.96, placebo 4.54, 95%CI: -0.481 to 1.641). No differences were found between the two groups (P=0.281) during this step. When comparing the VAS scale after the application of Pozzi tenaculum and cannula (EMLA 1.06, placebo 3.34, 95%CI: 1.495-3.065) and after cervical traction (EMLA 2.54, placebo 3.46, 95%CI: 0.034-1.806), significantly less pain was experienced by the EMLA group than the placebo group: P=0.000 and P=0.042, respectively. CONCLUSION: Endocervical and exocervical topical application of EMLA 10 min before performing hysterosalpingography significantly reduced pain during cervical manipulation with tenaculum and cannula and during cervical traction, but did not reduce pain during injection of contrast that was the most painful step.

Radiologic approach to the diagnosis of infectious pulmonary diseases in patients infected with the human immunodeficiency virus.

Nearly all patients infected with HIV experience respiratory infection at some point in the course of their illness. The spectrum of infections is varied and in order to generate a useful differential diagnosis based on imaging findings it is imperative for the radiologist to be aware of changing trends in disease prevalence and epidemiology, and the possible pathology related to new therapies. The characterization of the radiographic pattern in correlation with clinical findings and laboratory values (in particular the degree of immunosuppression as reflected in the CD4 level) would be helpful in narrowing the differential diagnosis of infectious pulmonary disease in HIV-positive patients. The most common radiologic patterns considered include areas of ground-glass, consolidation, nodules, and lymphadenopathy. We also include airways diseases and cavitary/cystic lesions because their prevalence has increased over recent years, and we also mention the significance of a normal chest radiograph in the suspicion of a lung infection. In most cases, the clinical and radiographic findings are sufficient for confident diagnosis. The radiologic diagnosis of thoracic infections in patients with AIDS has improved with the use of CT. The greatest value of CT is in excluding lung disease when the radiographic findings are equivocal and in confirming the presence of clinically suspected disease when the radiograph is normal.
