CSF velocity MR imaging is useful in the selection of patients with NPH to undergo shunt formation.

SUMMARYGene transfer has potential as a once-only treatment that reduces viral load, preserves the immune system, and avoids lifetime highly active antiretroviral therapy. This study, the first randomized, double-blind, placebo-controlled, phase II cell-delivered gene transfer clinical trial, was conducted in 74 HIV-1 infected adults who received a tat/vpr specific anti-HIV ribozyme (OZ1) or placebo delivered in autologous CD34+ hematopoietic progenitor cells. There were no OZ1-related adverse events. There was no statistical difference in viral load between the OZ1 and placebo group at the primary end-point (average at weeks 47 and 48) but time weighted areas under the curve from weeks 40-48 and 40-100 were significantly lower in the OZ1 group. Throughout the 100 weeks, CD4+ lymphocyte counts were higher in the OZ1 group. This study provides the first indication that cell-delivered gene transfer is safe and biologically active in HIV patients and can be developed as a conventional therapeutic product.

The yield and impact of open lung biopsies in patients with hematologic malignancies and unexplained pulmonary processes were assessed and analyzed to determine factors that affected the yield. Records of 63 patients with hematologic malignancy, who underwent 67 open lung biopsies for diagnosis of an unknown pulmonary process from 1996 to 1998 at Memorial Sloan-Kettering Cancer Center, were retrospectively reviewed. A specific diagnosis was found in 41 (62%) of the biopsies. Changes in therapy were made in 37 (57%) of patients after biopsy results, but in 69% of those with a specific diagnosis. Survival at 30 and 90 d was increased in those with specific rather than a nonspecific pulmonary diagnosis. The factor most predictive of finding a specific diagnosis was the presence of a focal rather than a diffuse radiographic abnormality (79% versus 36%, p = 0.003). Neutropenic patients or those on mechanical ventilation had a low chance of finding a specific diagnosis. Having received pulmonary toxic chemotherapy in the 6 mo before the biopsy was associated with finding a nonspecific lung injury. Specific pulmonary diagnoses found were inflammatory diseases in 23% of cases, infections in 21%, and malignancy in 18%. Bronchiolitis obliterans with organizing pneumonia (BOOP) was the most common inflammatory disorder and fungi and bacteria were the most frequent infectious pathogens. Complications occurred in 13% of the biopsies, including five patients who required mechanical ventilation post-procedure; one death was associated with the biopsy. The risk was increased in those with less than 50,000 platelets. Complications were similar with video-assisted thoracoscopy (VATS) compared with thoracotomy. We conclude that open lung biopsy in patients with hematologic malignancy has a significant yield and impact on management of patients with hematologic malignancy.

The shortage of deceased organ donors has created a need for right lobe living donor liver transplantation (RLDLT) in adults. Concerns regarding donor safety, however, necessitate continuous assessment of donor acceptance criteria and documentation of donor morbidity. We report the outcomes of our first 101 donors who underwent right lobectomy between April 2000 and November 2004. The cohort comprised 58 men and 43 women with a median age of 37.8 years (range: 18.6-55 years); median follow-up is 24 months. The middle hepatic vein (MHV) was taken with the graft in 55 donors. All complications were recorded prospectively and stratified by grade according to Clavien's classification. Overall morbidity rate was 37%; all complications were either grade 1 or 2, and the majority occurred during the first 30 days after surgery. Removal of the MHV did not affect morbidity rate. There were significantly fewer complications in the later half of our experience. All donors are well and have returned to full activities. With careful donor selection and specialized patient care, low morbidity rates can be achieved after right hepatectomy for living donor liver transplantation.

This pathway seeks to outline a urology patient care strategy that reduces the transmission risk to both healthcare providers and patients, reduces the healthcare burden, and maintains appropriate patient care.
