Long-term preservation with interim evaluation of lungs from a non-heart-beating donor after a warm ischemic interval of 90 minutes.

OBJECTIVE: To investigate the value of in situ preservation and ex vivo evaluation of lungs from a non-heart-beating donor (NHBD) prior to long-term cold storage. SUMMARY BACKGROUND DATA: The use of pulmonary grafts from NHBD might alleviate the organ shortage. However, viability testing of these grafts is mandatory to transplant only those lungs with excellent function. METHODS: Pigs were divided into two groups. In the control group, lungs were flushed, explanted, and stored for 4 hours (4 degrees C). In the study group, pigs were killed and left untouched for 90 minutes. Thereafter, the lungs were cooled for 150 minutes via chest drains. Graft function of the left lung in both groups was assessed in an isolated ventilation and reperfusion circuit 4 hours after death. The lung was then cooled and stored. Twenty-four hours after death, the pulmonary graft was reassessed in the same model. RESULTS: We did not observe a statistical significant difference between the two groups in pulmonary vascular resistance, mean airway pressure, and partial oxygen tension at each time point. There was also no statistical significant difference in wet-to-dry weight ratio. Finally, no statistical difference was found within both groups comparing the assessment at 24 hours with the interim evaluation at 4 hours. CONCLUSIONS: These data demonstrate that: 1) 90 minutes of warm ischemia and 150 minutes of intrapleural cooling do not affect pulmonary graft function; and 2) NHBD lungs can be safely preserved up to 24 hours. Finally, we have demonstrated that interim ex vivo evaluation of NHBD lungs is a valid and safe method to assess graft function.

The attitudes, concerns, gloving practices and knowledge of nurses in a Taiwanese hospital regarding AIDS and HIV.

Many studies have documented nurses' attitudes and concerns regarding AIDS/HIV, but little is known about Taiwanese nurses. We documented attitudes, concerns, gloving practices and practical AIDS/HIV knowledge of 1090 nurses from one metropolitan hospital in Changhua City, Taiwan. The response rate was 80.9%. Both HIV and hepatitis contraction in the workplace was nurses' main concern. Two hundred and ten nurses (19.3%) were seriously considering leaving nursing because of fear of contracting AIDS/HIV. Virtually all nurses considered it their right to be informed of the presence of HIV-positive patients in their direct work area and many believed that HIV testing of patients should be mandatory. Practical AIDS/HIV knowledge was deficient. These Taiwanese nurses have concerns and fears that might be related to deficiencies in practical AIDS/HIV knowledge. Continuous educational programmes are recommended to alleviate these nurses' attitudes and concerns regarding AIDS/HIV.

Obstetric implications of burns in pregnancy.

Analysis of 50 patients with burns in pregnancy has allowed the objective consideration of obstetric implications. Patients in the second and third trimester of pregnancy with burns of greater than or equal to 50% should be delivered immediately as maternal death is otherwise certain and fetal survival rate is not improved by waiting. Vaginal delivery has always proved possible, even in the presence of perineal burns but caesarean section should be considered and may be preferred. Patients in the first trimester may survive with more extensive burns and possible reasons for this are discussed. Pregnancy testing on admission should be mandatory in burns of women of reproductive age. In patients with burns of less than 40% in the second and third trimesters, spasmolytics should be used to suppress spontaneous labour and to cover operations. Greater fetal maturity without worsening maternal prognosis can thus be achieved. Insufficient data exist to recommend this for burns of between 40 and 50%.

Burn wound depth assessment--is laser Doppler imaging the best measurement tool available?

Accurate early assessment of burn wound depth is increasingly important in clinical decision-making. Clinimetric principles are absolutely mandatory while developing a new test or tool for use in the clinical setting. This article critically evaluates the clinimetrics of a powerful tool for assessment of burn depth and whether Laser Doppler Imaging can meet those criteria by virtue of differentiation between superficial and deep burns.

Intrathecal immunoglobulin synthesis in multiple sclerosis: effect of corticosteroids and azathioprine.

The objective of this study was to investigate quantitative and qualitative intrathecal IgG synthesis in 51 patients with clinically definite multiple sclerosis, taking previous immunosuppressive treatment into account. Four formulae were used to assess quantitative synthesis. Oligoclonal bands (OB) were investigated using isoelectric focusing (IEF) and silver staining. Abnormal quantitative values were detected in 42 (82%) patients, whereas OB occurred in 38 (74.5%) patients. Steroid therapy lowered quantitative synthesis in 6 out of 9 patients when given within 3 months before lumbar puncture (LP). Untreated patients with OB systematically had abnormal formulae. Patients treated with corticosteroids 10 or more months prior to LP had abnormal formulae. This fact suggests a transient depressor effect of steroids on quantitative synthesis. OB were present in patients recently treated with corticosteroids. Quantitative synthesis was higher in patients with OB than in those without OB. Azathioprine treatment did not significantly lower quantitative synthesis. We conclude that for routine purposes evaluation of intrathecal immunoglobulin synthesis could begin by performing quantitative tests. IEF seems to be mandatory for patients with normal formulae who have recently been treated with steroids.

Further observations on the prevention of experimental proliferative vitreo-retinopathy by 5-fluorouracil.

The rate of retinal detachment in fellow control eyes of rabbits following fibroblast administration is progressively lower with increased dose of 5-Fluorouracil in the test eyes. Thus, it seems mandatory to choose control eyes in other animals rather than the fellow eyes of the treated ones. Retinal detachment appeared in the second week or earlier after intravitreal fibroblast administration. However, in eyes treated intravitreally with 5-Fluorouracil, retinal detachment or pucker appeared later, even in the second month suggesting routine follow-up of at least 2 months in future studies.

Skier's thumb--the significance of bony injuries.

In a retrospective study to determine the anatomic nature of injuries in thumbs that were treated surgically for either fracture or instability, we reviewed 63 consecutive patients with acute skier's thumb injury. Of the 63 thumbs, 25 (40%) had a fracture. Surgical exploration showed 2 fracture types: a fragment that was attached to the ulnar collateral ligament, and a fragment that was not attached to the ulnar collateral ligament. The 1st type, corresponding to true avulsion fracture of the ulnar collaternal ligament, was found in 8 cases; the same fracture type was seen in another 7 cases, with an isolated fragment that was not attached to the ligament. Such an isolated fragment was observed in 10 other cases in which the ulnar collateral ligament was completely disrupted. This type of bony fragmentation cannot be differentiated from a bony avulsion of the ulnar collateral ligament on routine films. Therefore, stress testing the injured thumb is mandatory even when bony avulsion fracture with minimal displacement is suspected from a radiograph, as indeed the fracture may not be a bony avulsion but may be a fragmentation of the ulnar volar aspect of the proximal phalanx associated with a complete disruption of the ulnar collateral ligament.

Kawasaki disease.

Kawasaki disease is a leading cause of acquired heart disease in children in the USA. An acute vasculitis of unknown etiology, it occurs predominantly in infancy and early childhood, and more rarely in teenagers. Coronary artery aneurysms or ectasia develop in approximately 15-25% of children with the disease. Treatment with intravenous gamma globulin, 2 g per kg, in the acute phase reduces this risk three- to fivefold. Angiographic resolution occurs in approximately one-half of aneurysmal arterial segments, but these show persistent histologic and functional abnormalities. The remainder continue to be aneurysmal, often with development of progressive stenosis or occlusion. The worst prognosis occurs in children with so-called 'giant aneurysms', i.e. those with a maximum diameter greater than 8 mm, because thrombosis is promoted both by sluggish blood flow within the massively dilated vascular space and by the frequent development of stenotic lesions. Serial stress tests with myocardial imaging are mandatory in the management of patients with Kawasaki disease and significant coronary artery disease to determine the need for coronary angiography and transcatheter interventions or coronary bypass surgery. Continued long-term surveillance in patients with and without detected coronary abnormalities is necessary to determine the natural history of Kawasaki disease.

Alternative field methods for measuring hearing protector performance.

In comparison with the mandatory noise reduction rating (NRR) testing of every hearing protector sold in the United States, real-world tests of hearing protector attenuation are scarce. This study evaluated data from three potential field-test methods as compared with the subject-fit data from Method B of ANSI S12.6-1997 for the E.A.R(R) Express trade mark Pod Plug trade mark. The new field-test methods were the FitCheck headphone (FCH) method, FitCheck in sound field (FCSF) method, and bone-conduction loudness balance (BCLB) method, all of which can be administered in small single-person audiometric booths such as are commonly found in industry. Twenty normal-hearing and audiometrically competent subjects naive to hearing protector use were tested with the laboratory and the three field-test methods in a repeated-measures design. Repeated-measures models with structured covariance matrices were used to analyze the data. Significant effects were found for method, frequency, and first-order frequency-by-gender and frequency-by-method interactions. These effects and interactions were expected given the different psychophysical tasks. The FCSF and BCLB methods provided attenuations that were not significantly different from those found with Method B. Although the attenuations measured for the FCH method were statistically different (greater) than the attenuations from the other methods, the differences were within the magnitude of acceptable test-retest audiometric variability. The results suggest that the FCH and FCSF methods were both feasible and reliable methods for field testing. The FCH method is limited to testing earplugs, and the FCSF requires additional equipment to outfit the test booth, but could be used for testing all types of protectors.

Chromium cycling in soils and water: links, gaps, and methods.

The major links in the cycling of chromium in soils and in natural waters are between chromium(III) and chromium (VI). Between the larger links are lesser links involving processes of mobilization and oxidation of CrIII and reduction of CrVI. The gaps are mainly in our understanding of the factors that control these processes. If soluble CrIII is added to an "average" soil, a portion of it will become immediately oxidized by manganese oxides to CrVI. The rest of the CrIII may remain reduced for long periods of time, even in the presence of electron-accepting manganese oxides. However, this less available CrIII can be mobilized by low molecular weight organic complexers and then oxidized where redox conditions are optimal. Usually part of any CrVI added to a soil or sediment will be reduced instantly, especially under acid conditions. On the other hand, high concentrations of polluting CrVI may quickly exhaust the readily available reducing power of the matrix material and excess CrVI, the thermodynamically stable form in air, may persist for years in soils or lagoons without reduction. Cleanup of chromium pollution must involve the surrounding of both CrIII and CrVI with excesses of slowly available reducing substances and sealing them permanently from inputs of atmospheric oxygen. Monitoring the effectiveness of the measures is mandatory, but fortunately the chemical testing for CrVI in soil and water is simple and problem free compared with most colorimetric determinations.

The Kettering Diabetic Monitoring Programme: twelve months experience of an optometric practice-based scheme.

Over recent years the British Government has pursued a policy encouraging the integration of primary and secondary health care. This drive to promote the efficient delivery of primary care at local centres has seen the forging of co-operative alliances between various healthcare practitioners. A notable development has been the growth of optometric practice-based schemes for monitoring the eyecare of diabetic patients. This paper reports on the first twelve months operation (April 1995-March 1996, inclusive) of such a 'collaborative care' scheme operating in the Kettering Health Area of Northamptonshire. With the co-operation of their general medical practitioner (GMP) and under the case-review of the hospital-based specialist, diabetic patients attended participating optometric practices for an annual sight test and eye examination including mandatory fundus assessment under mydriasis. A brief 'ticked menu' report was subsequently forwarded to the patient's GMP for filing or action as necessary. A copy was also sent to the hospital clinic to enable updating of the diabetic patient database and for the authorisation of the supplementary fee payable to the examining optometrist. An audit of the first year of operation has indicated that those 92% of optometrists in the locality who participated in the programme logged 34% of the projected diabetic population of the Kettering Health Area. Of these individuals, 10.8% were identified as requiring referral for ophthalmological assessment, including 0.7% who needed urgent intervention. Approximately 80% of the referrals were assessed in the Ophthalmology Clinic within the twelve month timeframe of this first year audit; one-third of these patients received treatment and/or a second review over this period, the net outcome being that one-half of the original referrals were returned to the programme for continued routine annual screening. The scheme has received a funding allocation for a further financial year, with the possibility of its extension county-wide being kept under review.

The physician and the AIDS patient.

The grim statistics of the AIDS crisis have triggered a sweeping public policy debate over issues that directly affect the physician, including whether testing for AIDS should be mandatory, whether the physician has a duty to disclose known risks to an endangered third party or keep such information confidential, and whether the physician has a duty to treat AIDS patients. One state, California, has begun to respond to these issues through legislation. This article discusses the dilemmas facing physicians and the legal principles involved in the resolution of such conflicts.

Flutamide-induced hepatotoxicity: report of a case series.

OBJECTIVE: To evaluate the characteristics of flutamide induced hepatotoxicity. MATERIAL AND METHODS: In this retrospective study we have analyzed all cases of flutamide hepatotoxicity submitted to the Andalucian Registry of drug-induced liver disease. Data were collected using a structured reporting form. Causality assessment was performed using two clinical scales: the standard CIOMS scale and the recently developed María and Victorino scale. RESULTS: Nine of 185 patients (4.9%) were identified. In 8 male patients, mean age 75 years (range 65-83), flutamide was indicated for palliative therapy of disseminated prostatic carcinoma, and in one young female (14 years) was given for the treatment of facial hirsutism. The mean duration of the flutamide therapy was 151 days (range 4-443). All patients presented with overt liver injury, the most frequent features being asthenia, anorexia, weight loss, nausea, vomiting and jaundice. No patient showed hypersensitivity features. In two patients (22%) the hepatic damage evolved to fulminant liver failure, one of them undergoing a liver transplantation and the other subsequently died. An additional patient died of a non-hepatic related cause when his liver function was improving. Causality assessment by the two clinical scales did not exclude any case, but the two patients who died where classified as unlikely by the María and Victorino scale. CONCLUSIONS: Flutamide can induce severe acute hepatitis, probably due to an idiosyncratic metabolic mechanism. Liver tests monitoring should probably be mandatory during the first months of flutamide therapy and the drug withdrawn if transaminases began to increase.

Prevalence of seroreactivity among blood donors in rural population.

The seroreactivity pattern amongst blood donors in rural population was studied at S.R.T. Rural Medical College and Hospital, Ambajogai (M. S.). The study period was from January 1996 to December 2001. A total number of 12,240 blood donors were screened. The voluntary donation was 36.98% and replacement donors were 63.02%. No professional donor is bled in our blood bank. The HIV seroreactivity among voluntary donors was 1.56% and 2.11% in replacement donors. The HBsAg seroreactivity was 2.78% in voluntary donors and 4.84% in replacement donors. VDRL seroreactivity is 1.12% in replacement donors. No malarial parasite and HCV seroreactive donor was found in our study period. We have found the magnitude of hepatitis to be far more than that of HIV. Hence testing for HCV routinely is mandatory, besides HBsAg.

HIV-1 and HIV-2 infections in a high-risk population in Bombay, India: evidence for the spread of HIV-2 and presence of a divergent HIV-1 subtype.

A high-risk population (patients of a sexually transmitted disease clinic and the GT hospital in Bombay) was tested for antibodies against HIV-1 and HIV-2. Among 405 serum samples, 226 had previously been classified HIV-positive in India using different locally available enzyme-linked immunosorbent assay (ELISA) tests. The serology of 179 samples was unknown. All 405 samples were tested at the Georg-Speyer-Haus (GSH) with the Pasteur HIV-1/2-Combi-ELISA. Positive samples were further analyzed with HIV-1 and HIV-2 Western blot kits from Dupont and Pasteur, respectively. A very high seroprevalence of HIV was found in this population. Among the 179 unscreened samples, 69 (38.5%) were positive in the ELISAs as well as the Western blots for HIV-1 or HIV-2. Among the prescreened samples, only 174 (77%) were confirmed HIV-positive. Altogether, 243 of 405 sera were HIV-positive. Of these, 184 (76%) were reactive with HIV-1, 10 (4%) were reactive with HIV-2, and 49 (20%) had dual reactivity to HIV-1 and HIV-2. Previous data from the Indian Council of Medical Research had already suggested a possible high prevalence of HIV-1 in India. Our results confirm this view. The finding of a substantial spread of HIV-2 infection was, however, totally unexpected in India, but confirms our previous study which had already demonstrated the existence of HIV-2 in this country. Asia can thus no longer be considered free of HIV-2, and testing for HIV-2 appears mandatory, at least in India.(ABSTRACT TRUNCATED AT 250 WORDS)

Cell co-operation and hapten--carrier complexes.

The co-operation of spleen cells of carrier- and hapten--carrier-primed mice in antibody formation against the hapten part of complexes was studied in 550 rad whole body irradiated mice. Hapten--carrier complexes were prepared with the 2,4-dinitrophenyl group (DNP) as a hapten and heterologous bovine serum albumin (BSA) and isologous mouse immunoglobulin (MIg) as carriers. Priming of donor mice with carrier alone did not prepare for a secondary (IgG) response in the recipients of hapten--carrier. Priming of donors and challenge of recipients with the same hapten--carrier complex resulted in high IgG responses. Whereas donor and recipient immunization with complexes differing in the carrier did not give a secondary response, addition of cells of donors immunized with the carrier of the complex used for challenge, resulted in a secondary response. This was only possible when at least one of the complexes had an intermediate hapten:carrier ratio. Only an IgM or a low IgG response was obtained if both complexes had a high hapten:carrier ratio. Three determinants, namely hapten and carrier groups and new antigenic determinant (NAD), are suggested for antibody formation against hapten--protein complexes. In vivo treatment of donor cells with anti-thymocyte serum (ATS) or anti-plasma cell serum (APCS) and complement (C) suggested that: (1) T-cell epitopes are present on the carrier; (2) DNP groups are B-cell epitopes; (3) NAD and possibly DNP are T-cell epitopes; (4) synergism exists in the collaborative antibody response of B cells recongnizing DNP, T cell recognizing carrier and T cells recognizing NAD. Mitomycin treatment of donor cells was used to test whether cell division was mandatory. While the B cells were sensitive to mitomycin treatment, no effect of this drug was found on the helper activity of T cells.

Role of computed abdominal tomography (C.A.T. Scan) in the follow up of ovarian tumors.

This study evaluates the possible use of computed tomography not as an alternative diagnostic method but, rather, as a supplement to laparotomy in patients treated for ovarian cancer. The following conclusions can be drawn: in patients presenting no clinical evidence of persistent or relapsing disease C.T. Scan is not a mandatory but, rather, an optional test since it entails 25% false negatives, a 66.6% predictive value and because the involved patients will need, in any case, a further intervention. Conversely, C.T. Scan is clearly indicated in patients presenting clinical evidence of disease. It can prove helpful in detecting metastases in areas that prove difficult to be clinically examined; in assessing whether the retroperitoneal areas conceal neoplastic tissue or in planning the right operation for masses that have been palpated only before chemotherapy, and then in regression. When, despite chemotherapy, tumour progresses, surgery may became useless, and the C.T. Scan may therefore prove helpful in defining the condition and guiding non surgical treatment. Therefore, in the follow up of ovarian cancer the C.T. Scan may be performed on the basis of clinical course, instead than on a rigid aprioristic planning.

[Clinical experience of automated peritoneal dialysis].

For uremic patients on continuous ambulatory peritoneal dialysis who are complicated with peritonitis, hernia or burn out of meticulous procedure, automated peritoneal dialysis (APD) is a new alternative therapy. We started our APD program by continuous cyclic peritoneal dialysis (CCPD) method from October, 1991 and this study included 3 CAPD patients. Our studies showed high dose CCPD was better than CAPD in ultrafiltration and urea clearance with similar weekly creatinine clearance and weekly KT/V urea. During the one year treatment course, there was no signs of fluid overload. We performed once to twice day time exchange by low volume dialysate (1500-1600ml) There was no events of abdomen discomfort due to increase intraabdominal pressure or recurrent hernia in susceptible patient. The decrease in day time exchange frequency obviously reduced patients'loading. One patient changed to high dose CCPD due to underdialysis after stand CCPD therapy. Two patients returned to hemodialysis due to severe peritonitis and technique method, but careful assessment of dialysis adequacy with PET test and KT/V evaluation is mandatory.
