Abstract

PURPOSE: To determine the ability of new sub-2.0-mm-diameter microlaparoscopes to be used for diagnostic laparoscopy, 28 small-diameter laparoscopies (SDL) were performed during a 4-month-period. METHODS: These cases were performed under general anesthesia, with immediate follow-up confirmation with conventional laparoscopic equipment. An additional 13 SDL procedures were performed under analgosedation plus local anesthesia and were well tolerated by the patients. RESULTS: For the cases performed with conventional laparoscopic control, the visualization results were comparable in 27 of 28 procedures. In the nongeneral anesthesia SDL group, patients were highly satisfied and reported less post-procedural discomfort and minimal scar formation due to the smaller access ports. In this study, two types of microlaparoscopes were used. CONCLUSIONS: While both were adequate, the newer high-resolution microlaparoscope delivered an image much more similar to that which conventional laparoscopy and required little or no change in technique in order to obtain images. With the advent of this new endoscope technology with optics performance comparable to that of conventional laparoscopes, SDL has demonstrated to be a useful procedure for certain clinical indications.

Efficiencies of four versions of the AMPLICOR HIV-1 MONITOR test for quantification of different subtypes of human immunodeficiency virus type 1.

Three versions of a commercial human immunodeficiency virus (HIV) type 1 (HIV-1) load test (the AMPLICOR HIV-1 MONITOR Test versions 1. 0, 1.0+, and 1.5; Roche Diagnostics, Branchburg, N.J.) were evaluated for their ability to detect and quantify HIV-1 RNA of different genetic subtypes. Plasma samples from 96 patients infected with various subtypes of HIV-1 (55 patients infected with subtype A, 9 with subtype B, 21 with subtype C, 2 with subtype D, 7 with subtype E, and 2 with subtype G) and cultured virus from 29 HIV-1 reference strains (3 of subtype A, 6 of subtype B, 5 of subtype C, 3 of subtype D, 8 of subtype E, 3 of subtype F, and 1 of subtype G) were tested. Detection of subtypes A and E was significantly improved with versions 1.0+ and 1.5 compared to that with version 1. 0, whereas detection of subtypes B, C, D, and G was equivalent with the three versions. Versions 1.0, 1.0+, and 1.5 detected 65, 98, and 100% of the subtype A-infected samples from patients, respectively, and 71, 100, and 100% of the subtype E-infected samples from patients, respectively. Version 1.5 yielded a significant increase in viral load for samples infected with subtypes A and E (greater than 1 log10 HIV RNA copies/ml). For samples infected with subtype B, C, and D and tested with version 1.5, only a slight increase in viral load was observed (<0.5 log10). We also evaluated a prototype automated version of the test that uses the same PCR primers as version 1.5. The results with the prototype automated test were highly correlated with those of the version 1.5 test for all subtypes, but were lower overall. The AMPLICOR HIV-1 MONITOR Test, version 1.5, yielded accurate measurement of the HIV load for all HIV-1 subtypes tested, which should allow the test to be used to assess disease prognosis and response to antiretroviral treatment in patients infected with a group M HIV-1 subtype.

Evaluation of the oxoid dryspot streptococcal grouping kit for grouping beta-hemolytic streptococci.

The latex agglutination kits that are widely used for grouping of beta-hemolytic streptococci in clinical laboratories use liquid latex suspensions. The Oxoid Dryspot kit (Oxoid Ltd., Basingstoke, Hampshire, United Kingdom) uses predispensed latex dried onto reaction cards or cardboard strips. All streptococci of groups A (85 strains), B (87 strains), C (30 strains), D (38 strains), F (23 strains), and G (65 strains) were correctly grouped by using these reagents. The Oxoid Dryspot Streptococcal Grouping kit is a reliable method for grouping of the beta-hemolytic streptococci encountered in clinical laboratories.

Image manipulation and error estimation for MRI analysis.

Manipulation of MRI images prior to volumetric analysis is a common practice that may unwittingly lead to errors in measurement. In this study, we examine the effects of two types of image manipulation: changes in the total number of slices used to obtain volume estimates (slice sampling rate) and image rotation. A phantom containing two regularly-shaped and two irregularly-shaped regions of interest (ROIs) was scanned using an SPGR sequence and 1-mm slices. Changes in slice sampling rate produced marked effects on volume estimation of irregularly-shaped ROls. Comparatively little error was associated with changes in slice sampling rates for regularly-shaped ROIs. In addition, there was an interaction between image rotation in non-orthogonal planes and slice sampling rate. The data suggests that the ability to detect anatomical effects may be influenced by an investigator's choices concerning the number of slices included in a region of interest and image rotation when estimating volumes.
