Needle biopsy of renal allografts: comparison of two techniques

Two techniques for renal allograft biopsy were retrospectively evaluated to compare relative safety and efficacy. After ultrasound (US) localization of the kidney and biopsy with a hand-held 14-gauge cutting needle, an adequate specimen was obtained in 74 of 77 cases (96%). Major complications occurred in six of these 77 cases (8%). One hundred four biopsies were performed by using a smaller 18-gauge cutting needle with a spring-loaded biopsy "gun" and real-time US guidance. With this newer technique, specimens adequate for diagnosis were obtained in 99 biopsies (95%). There was a single major complication with this technique (1%). The 18-gauge needle with real-time US guidance yields comparably adequate specimens with a lower frequency of complications.

Use of the Silvermann-Franklin biopsy needle for the diagnosis of intra-sinusal lesions, especially of the maxillary sinus

This report proposes the use of a new technique in the diagnosis of pathology of the maxillary sinus, including neoplasm, using the Silvermann-Franklin" needle. The procedure consists of approaching the diseased sinus through the canine, as in conventional biopsies, with the removal of fragments using forceps. Ten patients with an X-ray suggesting a mass in the maxillary sinus were studied. An 80% correlation was found between the anatomical and pathological findings of the biopsy and the subsequent surgical findings. The advantages of this method include the low risk, performance under local anaesthetic in an out-patient mode, the possibility of obtaining the diagnosis prior to surgery, and the possibility of obtaining deep-seated tissue fragments.     

Tolerabilidad y efectividad del citrato de fentanilo oral transmucosa en el tratamiento a largo plazo del dolor irruptivo en pacientes oncológicos: estudio ECODIR

INTRODUCTION: Oral trans-mucosal fentanyl citrate (OTFC) is the one drug specifically developed for the management of breakthrough pain. This study assesses the long-term safety and efficacy of OTFC standard clinical conditions. Patients and methods. Six-month observational study performed on cancer patients with episodes of breakthrough pain. Safety was assessed by recording the advent of adverse events and efficacy by the evaluating the intensity of breakthrough pain. RESULTS: 174 cancer patients were recruited into the study. All adverse reactions reported were mild or moderate. OTFC was significantly faster (time to the commencement of pain relief: 12.7 +/- 11.4 vs 32.7 +/- 18.4 minutes; p < 0.001) and potent (post-treatment pain intensity: 3.4 +/- 1.5 vs 4.3 +/- 1.5; p < 0.001) than the previously-used drugs. CONCLUSIONS: This observational study confirms the good safety profile of OTFC as well as its effectiveness over long-term period treatment of breakthrough pain.
