BACKGROUND Previous research found precursor levels of the atrial natriuretic peptide (MR-proANP) to be promising prognostic markers. This study aims to validate these findings and describe patterns of MR-proANP in a large cohort of patients with lower respiratory tract infections. METHODS We conducted a multicenter prospective cohort study, and measured(More)
In this prospective, blinded study, we randomized 56 patients undergoing hallux valgus repair to receive continuous sciatic nerve block using a subgluteal (n = 28) or a posterior popliteal approach (n = 28) with a perineural stimulating catheter. Postoperatively, the stimulating catheter was connected to a patient-controlled analgesia pump with 0.0625%(More)
INTRODUCTION HIV-1 viral escape in the cerebrospinal fluid (CSF) despite viral suppression in plasma is rare [1,2]. We describe the case of a 50-year-old HIV-1 infected patient who was diagnosed with HIV-1 in 1995. Antiretroviral therapy (ART) was started in 1998 with a CD4 T cell count of 71 cells/ìL and HIV-viremia of 46,000 copies/mL. ART with zidovudine(More)
STUDY OBJECTIVE To compare duration of labor, mode of delivery, and local anesthetic consumed in women who received labor analgesia with epidural or combined spinal-epidural technique. DESIGN Retrospective, observational study. SETTING Delivery room of a university hospital. PATIENTS 788 nulliparous women in labor at term with cervical dilation(More)
One of the advantages of lower extremity peripheral nerve blocks compared with neuroaxial Neuraxial techniques is the lack of effect on urinary function. We report two cases of urinary incontinence during continuous sciatic nerve block with stimulating catheters placed using the posterior gluteal Labat approach. The two patients were able to control(More)
