Surveillance of Treated and Untreated Funguria in a University Hospital

Study Objective . To determine the influence of treatment on the microbiologic outcome of funguria. Design . Retrospective case series. Setting . A 300-bed tertiary care teaching hospital in a large metropolitan area. Subjects . 141 hospitalized patients, 18 years of age or older, with at least one urine culture positive (≥ 10² cfu/ml) for fungi. Interventions . Retrospective review of medical records to determine the microbiologic outcome of funguria. Main Results . Funguria developed rapidly in individuals with known predisposing factors. Urinalysis did not routinely detect the presence of fungi or pyuria. Symptoms such as fever, dysuria, and frequency were generally absent. Funguria persisted whether it was due to Candida albicans or non-albicans species. There were no statistical differences in the microbiologic outcomes of treated and untreated funguria. Conclusions . Funguria is a rapidly developing, often benign and persistent process. Minimizing predisposing risks, such as removing indwelling urinary catheters, is beneficial in its management. Pharmacologic treatment of funguria due to C. albicans or non-albicans species does not influence the microbiologic outcome.     

RENIN GENE POLYMORPHISM ASSOCIATED WITH ALDOSTERONE RESPONSIVENESS TO THE RENINANGIOTENSIN SYSTEM IN PATIENTS WITH ALDOSTERONE-PRODUCING ADENOMAS

1. Aldosterone levels in patients with unilateral aldosterone-producing adenomas may be responsive or unresponsive to the renin-angiotensin system, with the former often previously misdiagnosed as bilateral adrenal hyperplasia. 2. In tumours from patients in the responsive subgroup, renin mRNA is expressed in greater amounts than in tumours from patients in the unresponsive subgroup, or in normal adrenals. 3. We compared the frequency of four renin gene polymorphisms in peripheral blood DNA from the two subgroups and found significant associations between BglI, TaqI and HinfI restriction fragment length polymorphisms (RFLP) and aldosterone responsiveness. 4. Allelic variation in the constitutive renin gene was associated with a specific cause of hypertension.     

High-Temperature Short-Time Heat Inactivation of HIV and Other Viruses in Human Blood Plasma

An ultra-short-time heating system was used to process blood plasma spiked with various viruses (HIV, vesicular stomatitis virus, encephalomyocarditis virus). Virus reduction and recovery of plasma proteins were measured at various temperatures from 65 to 85 degrees C. Processing at 77 degrees C and 0.006 s resulted in a high level of virus kill, including greater than or equal to 4.4 log10 HIV, while maintaining protein structure and activity essentially intact.     

The vascular access coordinator role: an interview with Donna Carlton by Betsy King.

In summary, the access coordinator is at the center of our access program at UAB. The coordinators can make decisions based on the calls we receive from the nursing staff and reports obtained from procedures. The ability to relay information to the entire team rather than simply data entry staff, makes us a central focal area for our access team. This type of model is working to help us achieve better patient outcomes. We provide many services but the most important is follow-up. As a result, we are able to achieve optimal outcomes for our patients.     

Ocular findings in the chromosome 22q11.2 deletion syndrome.

PURPOSE: To identify the ocular features of the chromosome 22q11.2 deletion syndrome and to provide ophthalmologic examination recommendations for affected patients. METHODS: Ocular abnormalities were evaluated prospectively in patients with 22q11.2 deletion at the Children's Hospital of Philadelphia between 1997 and 1999. RESULTS: Ninety patients with confirmed 22q11.2 deletion were examined. Posterior embryotoxon was found in 49%, tortuous retinal vessels in 34%, eyelid hooding in 20%, strabismus in 18%, ptosis in 4%, amblyopia in 4%, and tilted optic nerves in 1%. CONCLUSIONS: The high incidence of ocular conditions that can potentially affect visual development suggest that children with 22q11.2 deletion should undergo a comprehensive eye examination upon diagnosis of the condition with follow-up as indicated by the findings in each case. In addition, knowledge of the ocular findings, in conjunction with certain cardiac, otolaryngologic, immunologic, and other systemic findings, may alert physicians to the possibility of a chromosome 22q11.2 deletion.     

Clinical experience with Mentor inflatable penile prosthesis in 206 patients

The Mentor inflatable penile prosthesis (IPP) has been implanted in 206 patients with organic (95.2%) or psychologic (4.8%) impotency. The patients have been followed up for an average of 18.1 (4-42) months. A satisfactory result has been achieved in 98 per cent of these patients. A life analysis of the series shows that 88 per cent of all devices implanted will survive forty-two months without mechanical failure. One hundred sixty-four of these patients had not had previous penile surgery while 42 had had one or more penile prostheses implanted previously. The projected forty-two-month survival for the Mentor prosthesis in these subgroups is 94 per cent and 74 per cent, respectively. The improved life expectancy of the Mentor IPP, compared with the Scott IPP, is due to the superior durability of Mentor's polyurethane cylinders and to the increased reliability of the Mentor snap-on connector system. In this respect, there have been only one cylinder failure and 3 connector failures in the Mentor series. The connector failures occurred early in the series before the development of connector pliers; there have been no connector failures in the last 202 consecutive implantations. Wear-induced tubing leaks, the most common cause of device failure, occurred in 2.9 per cent of all implantations. Tubing failures were more common in patients who have had previous surgery, occurring in 9 per cent of salvage procedures and 1.3 per cent of primary implantations. The reason for the difference in tubing survival in virgin and salvage procedures is unknown; possibly the subcutaneous scar tissue present in secondary surgical procedures increases the chance of tubing segments touching and abrasing each other. Laboratory studies suggest that the nylon-reinforced tubing used in the manufacture of devices implanted since 1985 is more durable than is the standard silicone tubing used in the construction of devices implanted previously.     

Using Humor to Help Children With Pain

Humor has become a popular topic in health care recently. One of the suggested benefits is to help control pain. Although no scientific research to date has validated this effect, there is some theoretical and empirical support for the use of humor especially with children. Methods to implement the uses of humor in a clinical setting are suggested inappropriate uses of humor are also discussed. The need for scientific research is stressed.
