Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immune responses and infection outcomes were evaluated in 2,686 patients with varying immune-suppressive disease states after administration of two Coronavirus Disease 2019 (COVID-19) vaccines. Overall, 255 of 2,204 (12%) patients failed to develop anti-spike antibodies, with an additional 600 of 2,204 (27%) patients generating low levels (<380 AU ml-1). Vaccine failure rates were highest in ANCA-associated vasculitis on rituximab (21/29, 72%), hemodialysis on immunosuppressive therapy (6/30, 20%) and solid organ transplant recipients (20/81, 25% and 141/458, 31%). SARS-CoV-2-specific T cell responses were detected in 513 of 580 (88%) patients, with lower T cell magnitude or proportion in hemodialysis, allogeneic hematopoietic stem cell transplantation and liver transplant recipients (versus healthy controls). Humoral responses against Omicron (BA.1) were reduced, although cross-reactive T cell responses were sustained in all participants for whom these data were available. BNT162b2 was associated with higher antibody but lower cellular responses compared to ChAdOx1 nCoV-19 vaccination. We report 474 SARS-CoV-2 infection episodes, including 48 individuals with hospitalization or death from COVID-19. Decreased magnitude of both the serological and the T cell response was associated with severe COVID-19. Overall, we identified clinical phenotypes that may benefit from targeted COVID-19 therapeutic strategies.

Abstract
Fyrolflex resorcinol bis-diphenylphosphate (RDP) was evaluated in a two-generation reproductive study as part of a program to assess the overall toxicology of this flame retardant. RDP was administered to male and female Sprague-Dawley rats in the diet at concentrations of 1000, 10,000 or 20,000 ppm. The control group was given diet alone. Parental (P1) animals were treated for 10 weeks prior to mating, during the 2-week mating period, throughout gestation, and through lactation until sacrifice. The F1 generation (P1 offspring) was treated following a regimen similar to P1. The F2 generation was not treated. No significant difference in Utter survival was observed between the control and treated groups. Body weights were significantly decreased in P1 rats during the 1st week due to an initial flavor aversion of the test substance in the diet. Body weight, weight gains, and food consumption were decreased in the test substance-treated pups (F1) during lactationand after weaning. These changes were also attributed to a flavor aversion. Anogenital distance was similar in the control and high-dose groups, whereas vaginal opening and preputial separation were delayed in the 10,000 and 20,000 ppm groups, and were considered to be secondary to the reduction in F1 body weight. Neither parents nor offspring exhibited any test substance-related clinical signs of toxicity. Vaginal cytology and cyclicity and male reproductive functions (sperm count, motility, and morphology) were unaffected by treatment. Mating performance was similar in the treated groups relative to the control. No treatment-related lesions were noted in the reproductive organs. Increased liver weight and associated hepatic periportal hypertrophy were observed in the RDP-treated animals (P1 and F1). In conclusion, there were no adverse effects on reproductive performance or fertility parameters associated with RDP administration in the diet. Fyrolflex RDP administered for greater than 13 weeks and up to the entire life span (i.e., F1, from conception to euthanasia) resulted in increased liver weights with associated periportal hypertrophy. This change was considered an adaptive process associated with RDP metabolism in the liver.

Abstract
Background Animal African trypanosomiasis (AAT) is one of the biggest constraints to livestock production and a threat to food security in sub-Saharan Africa. In order to optimise the allocation of resources for AAT control, decision makers need to target geographic areas where control programmes are most likely to be successful and sustainable and select control methods that will maximise the benefits obtained from resources invested. Methods The overall approach to classifying cattle-owning communities in terms of AAT vulnerability was based on the selection of key variables collected through field surveys in five sub-Saharan Africa countries followed by a formal Multiple Correspondence Analysis (MCA) to identify factors explaining the variations between areas. To categorise the communities in terms of AAT vulnerability profiles, Hierarchical Cluster Analysis (HCA) was performed. Results Three clusters of community vulnerability profiles were identified based on farmers’ beliefs with respect to trypanosomiasis control within the five countries studied. Cluster 1 communities, mainly identified in Cameroon, reported constant AAT burden, had large trypanosensitive (average herd size = 57) communal grazing cattle herds. Livestock (cattle and small ruminants) were reportedly the primary source of income in the majority of these cattle-owning households (87.0 %). Cluster 2 communities identified mainly in Burkina Faso and Zambia, with some Ethiopian communities had moderate herd sizes (average = 16) and some trypanotolerant breeds (31.7 %) practicing communal grazing. In these communities there were some concerns regarding the development of trypanocide resistance. Crops were the primary income source while communities in this cluster incurred some financial losses due to diminished draft power. The third cluster contained mainly Ugandan and Ethiopian communities which were mixed farmers with smaller herd sizes (average = 8). The costs spent diagnosing and treating AAT were moderate here. Conclusions Understanding how cattle-owners are affected by AAT and their efforts to manage the disease is critical to the design of suitable locally-adapted control programmes. It is expected that the results could inform priority setting and the development of tailored recommendations for AAT control strategies.

Abstract
BACKGROUND Post-thrombotic syndrome (PTS) is a frequent chronic complication of deep vein thrombosis (DVT). OBJECTIVE In the BioSOX study, we investigated whether inflammation markers predict the risk of PTS after DVT. METHODS We measured C-reactive protein (CRP), ICAM-1, interleukin (IL)-6, and IL-10, at baseline, and 1 month and 6 months after a first proximal DVT, among 803 participants in the SOX trial. Participants were prospectively followed for 24 months for development of PTS. RESULTS Median CRP levels at 1 month, ICAM-1 levels at baseline, 1 month and 6 months, IL-6 levels at 1 month and 6 months and IL-10 levels at 6 months were higher in patients who developed PTS than in those who did not. Multivariable regression with the median as a cutoff showed risk ratios (RRs) for PTS of 1.23 (95% confidence interval [CI] 1.05-1.45) and 1.25 (95% CI 1.05-1.48) for ICAM-1 at 1 month and 6 months, respectively, and 1.27 (95% CI 1.07-1.51) for IL-10 at 6 months. Quartile-based analysis demonstrated a dose-response association between ICAM-1 and PTS. ICAM-1 and IL-10 were also associated with PTS severity. Analysis of biomarker trajectories after DVT demonstrated an association between the highest-trajectory group of ICAM-1 and PTS. CONCLUSIONS In this prospective study, ICAM-1 over time was most consistently associated with the risk of PTS. Further study is required to confirm these findings and assess their potential clinical relevance.

Abstract
This paper describes a rapid, standardised method for testing the susceptibility to bluetongue virus (BTV) of northern Palaearctic Culicoides species midges that can be used to assess the competence of both field-caught and laboratory-infected midges. The method has been used to show that Culicoides scoticus can replicate btv serotype 8 and BTV serotype 9 strains to more than 3 log(10) TCID50/midge, the first evidence of the potential of this species to transmit BTV.

Abstract
Inosine 5'-monophosphate dehydrogenase 1 (IMPDH1) catalyzes the rate-limiting step of the de novo pathway for purine synthesis and is a major target of the immunosuppressive drug mycophenolic acid (MPA). Few variants of the IMPDH1 gene have been reported. The objective of this study was to identify and characterize IMPDH1 variants to determine whether genetic variation contributes to differences in MPA response and toxicity in transplant patients. Seventeen genetic variants were identified in the IMPDH1 gene with allele frequencies ranging from 0.2 to 42.7%. In this study, 191 kidney transplant patients who received mycophenolate mofetil were genotyped for IMPDH1. Two single-nucleotide polymorphisms, rs2278293 and rs2278294, were significantly associated with the incidence of biopsy-proven acute rejection in the first year post-transplantation. Future studies of the multifactorial nature of acute rejection must consider IMPDH1 polymorphisms in MPA-treated patients.

Abstract
The chronic shortage of deceased kidney donors has led to increased utilization of donation after cardiac death (DCD) kidneys, the majority of which are procured in a controlled setting. The objective of this study is to evaluate transplantation outcomes from uncontrolled DCD (uDCD) donors and evaluate their utility as a source of donor kidneys. From January 1995 to December 2004, 75,865 kidney-alone transplants from donation after brain death (DBD) donors and 2136 transplants from DCD donors were reported to the United Network for Organ Sharing. Among the DCD transplants, 1814 were from controlled and 216 from uncontrolled DCD donors. The log-rank test was used to compare survival curves. The incidence of delayed graft function in controlled DCD (cDCD) was 42% and in uDCD kidneys was 51%, compared to only 24% in kidneys from DBD donors (p < 0.001). The overall graft and patient survival of DCD donors was similar to that of DBD donor kidneys (p = 0.66; p = 0.88). Despite longer donor warm and cold ischemic times, overall graft and patient survival of uDCD donors was comparable to that of cDCD donors (p = 0.65, p = 0.99). Concerted efforts should be focused on procurement of uDCD donors, which can provide another source of quality deceased donor kidneys.

Abstract
The use of expanded criteria donors (ECD) has been proposed to help combat the discrepancy between organ availability and need. ECD kidneys are associated with delayed graft function (DGF) and worse long-term survival. The aim of this study is to evaluate the impact of pulsatile perfusion (PP) on DGF and graft survival in transplanted ECD kidneys. From January 2000 to December 2003, 4618 ECD kidney-alone transplants were reported to the United Network for Organ Sharing. PP was performed on 912 renal allografts. The prognostic factors of DGF were analyzed using multivariate logistic regression analysis. Risk factors for reduced allograft viability were greater in donors and recipients of PP kidneys. Three-year graft survival of ECD kidneys preserved with PP was similar to cold storage (CS) kidneys. The incidence of DGF in PP kidneys was significantly lower than CS kidneys (26% vs. 36%, p < 0.001). Despite having a greater number of risk factors for reduced graft viability, the ECD-PP kidneys had similar graft survival compared to ECD-CS kidneys. The use of PP, by decreasing the incidence of DGF, may possibly lead to lower overall costs and increased utilization of donor kidneys.

Abstract
BACKGROUND Pseudoaneurysms of the extrahepatic arterial vasculature are relatively uncommon lesions following surgery and trauma. In this report we analyze the presentation, management and outcomes of these vascular lesions. Of the related surgical procedures, the reported incidence is highest following laparoscopic cholecystectomy. We hereby analyze the literature on this subject and report our experience, specifically with extrahepatic pseudoaneurysms, drawing an important distinction from intrahepatic pseudoaneurysms. METHODS From September 1995 until July 2004, six patients, including three males and three females with a mean age of 67 years, were treated for seven extrahepatic arterial pseudoaneurysms. Patients were evaluated by endoscopy, ultrasound, computerized tomography, and angiography. Management included coil embolization or arterial ligation and/or hepatic resection. RESULTS The mean pseudoaneurysm size was 4.9-cm (range 1.0-11.0-cm) and the locations included the right hepatic artery (n = 5), inferior pancreaticoduodenal artery (n = 1), and gastroduodenal artery (n = 1). All six patients had prior surgical or percutaneous procedures. Median latency period between the original procedure and treatment of pseudoaneurysm was 17 weeks (range one month-16 years). Clinical features ranged from the dramatic presentation of hypotension secondary to intraperitoneal aneurysmal rupture to the subtle presentation of obstructive jaundice secondary to pseudoaneurysm mass effect. The range of patient presentations created diagnostic challenges, proving that accurate diagnosis is made only by early consideration of pseudoaneurysm. Management was ligation of the right hepatic artery (n = 4) and embolization of the pseudoaneurysms (n = 2). Post-treatment sequelae included liver failure requiring liver transplant (n = 1), intrahepatic biloma requiring percutaneous drainage (n = 1) and cholangitis with right hepatic duct strictures requiring right lobectomy and biliary reconstruction (n = 1). These complications followed arterial ligation, with no complications resulting from embolization. All six patients are alive and well after a mean follow-up of 53 months. CONCLUSIONS Our six patients demonstrate the diversity and unpredictability with which a pseudoaneurysm of the extrahepatic arterial vasculature may present in terms of initial symptoms, prior procedures, and the latency period between presentation and prior procedure. Through our experience and an analysis of the literature, we recommend a diagnostic and management approach for these patients.

Abstract
The UNOS donor population was examined from 1999 to 2002, and approximately 25% of the over 23,000 donors were biopsied (Bx). There was a significant trend (P < .001) of older donors, cardiovascular accident, and hypertension in the Bx group versus the non-Bx group. The percent GS was directly correlated (P < .001) to graft survival, delayed graft function, and primary nonfunction. Cox regression showed significant relative risk (RR) for >10% GS, hypertension, donors over the age of 50, and African American recipients. RR in donors with >10% GS could be ameliorated (P < .001) by choosing donors with <5 HLA-A, -B, or -DR mismatches (MM), or recipients who were nonsensitized, and/or first transplant. Risk should be managed in donors by choosing appropriate recipients and high-risk immunosuppresion protocols.

Abstract
This study evaluated the potential reproductive toxicity of phenol in a rat two-generation reproduction study, which included additional study endpoints, such as sperm count and motility, developmental landmarks, histological evaluation of suspect target organs (liver, kidneys, spleen, and thymus), weanling reproductive organ weights, and an immunotoxicity screening plaque assay. Phenol was administered to 30 Sprague-Dawley rats/sex/group in the drinking water at concentrations of 0, 200, 1000, or 5000 ppm. Parental (P1) animals were treated for 10 weeks prior to mating, during mating, gestation, lactation, and until sacrifice. The F1 generation (P1 offspring) was treated using a similar regimen, while the F2 generation was not treated. After mating, 10 P1 males/group were evaluated using standard clinical pathology parameters and an immunotoxicity screening plaque assay. Significant reductions in water and food consumption were observed in the 5000-ppm group in both generations; corollary reductions in body weight/body weight gain were also observed. Mating performance and fertility in both generations were similar to controls, and no adverse effects on vaginal cytology or male reproductive function were observed. Vaginal opening and preputial separation were delayed in the 5000-ppm group, and were considered to be secondary to the reduction in F1 body weight. Litter survival of both generations was reduced in the 5000-ppm group. Absolute uterus and prostate weights were decreased in the F1 generation at all dose levels; however, no underlying pathology was observed and there was no functional deficit in reproductive performance. Therefore, these findings were not considered to be adverse. No evidence of immunotoxicity was noted in the 5000-ppm group. The effects noted at the high concentration were presumed to be associated with flavor aversion to phenol in the drinking water. Based on a comprehensive examination of all parameters, the no-observable-adverse-effect level (NOAEL) for reproductive toxicity of phenol administered in drinking water to rats is 1000 ppm. The corresponding daily intake of phenol for an adult rat at the NOAEL of 1000 ppm is equivalent to about 70 mg/kg/day for males and 93 mg/kg/day for females.

Abstract
OBJECTIVES To present a series of 5 patients with solitary metastatic renal cell carcinoma (RCC) to the pancreas after radical nephrectomy at our institution and review the published reports of this rare event. METHODS A retrospective review of the records of 5 patients with histologically confirmed RCC metastatic to the pancreas after radical nephrectomy was performed. A total of 5 patients (4 men, 1 woman) with a median age of 56 years (range 54 to 68) underwent radical nephrectomy for primary RCC. The pathologic stage was Robson I (n = 3) or Robson III (n = 2), with a left-sided tumor occurring in 3 patients and a right-sided tumor in 2 patients. The median interval from nephrectomy to the diagnosis of the pancreatic metastasis was 12 years (range 4 to 15). All patients were symptomatic at presentation, including weight loss (n = 3), abdominal pain (n = 3), early satiety (n = 1), steatorrhea (n = 1), and/or hemosuccus pancreaticus (n = 1). RESULTS All pancreatic metastases were hypervascular on imaging studies, and surgical removal was accomplished by pancreaticoduodenectomy (n = 3), partial pancreatectomy (n = 1), or subtotal pancreatectomy (n = 1). One patient died of disseminated disease 12 months after pancreatic resection. Two other patients had recurrences in the lung (n = 1) at 5 months or the pancreas/liver (n = 1) at 48 months. Both of these patients underwent a second resection and were disease free at 2 and 12 months afterward. The two remaining patients were disease free at 7 and 24 months after pancreatic resection. CONCLUSIONS RCC is an unpredictable tumor that may demonstrate very late metastases even from early-stage lesions. Aggressive surgical management of isolated pancreatic lesions offers a chance of long-term survival.

Abstract
OBJECTIVE To describe our experience with total hepatectomy and liver transplantation as treatment for primary hepatoblastoma (HBL) and hepatocellular carcinoma (HCC) in children. STUDY DESIGN A retrospective analysis of the perioperative course of 31 children with unresectable primary HBL (n = 12) and HCC (n = 19) who underwent transplantation between May 1989 and December 1998. Systemic (n = 18) and intraarterial (n = 7) neoadjuvant chemotherapy were administered; follow-up ranged from 1 to 185 months. RESULTS For HBL, 1-year, 3-year, and 5-year posttransplantation survival rates were 92%, 92%, and 83%, respectively. Intravenous invasion, positive hilar lymph nodes, and contiguous spread did not have a significant adverse effect on outcome; distant metastasis was responsible for 2 deaths. Intraarterial chemotherapy was effective in all patients treated. For HCC, the overall 1-year, 3-year, and 5-year disease-free survival rates were 79%, 68%, and 63%, respectively. Vascular invasion, distant metastases, lymph node involvement, tumor size, and gender were significant risk factors for recurrence. Intraarterial chemotherapy was effective in 1 of 3 patients. Six patients died of recurrent HCC, and 3 deaths were unrelated to recurrent tumor. CONCLUSION Liver transplantation for unresectable HBL and HCC can be curative. Risk factors for recurrence were significant only for HCC, with more advanced stages amenable to cure in the HBL group.

Abstract
Venous thromboembolism is a common disease in the community and the most frequent preventable cause of hospital death. Acquired and inherited risk factors for thrombosis have been extensively studied over the past two decades. These factors and the clinical setting allow the stratification of most hospitalized patients into low-, moderate-, and high-risk groups. For patients in the moderate- and high-risk categories, routine thromboprophylaxis can decrease the morbidity and mortality from thromboembolic complications as well as reduce patient care expenditures. Low-dose heparin is generally the most appropriate prophylaxis for moderate-risk patients, and either low molecular weight heparin or adjusted-dose warfarin is generally the most appropriate for high-risk patients.

Abstract
OBJECTIVE To evaluate the safety and tolerability of subcutaneous (s.c.) cladribine therapy in patients with chronic progressive multiple sclerosis (CPMS), and to evaluate the effects on lymphocyte subsets. BACKGROUND Cladribine, a synthetic antineoplastic agent with immunosuppressive effects, may favourably affect the course of CPMS. However results of a previous reported clinical trial showed significant myelosuppression in some patients. DESIGN/METHODS 19 patients with severe (mean extended disability status score [EDSS] = 6.7) CPMS were treated on a compassionate basis with cladribine 0.07 mg/kg/day s.c. for 5 days per cycle, repeated every 4 weeks for a total of 6 cycles. Patients underwent clinical evaluation, EDSS, and hematologic analysis before, during, and following therapy. RESULTS The treatment was very well tolerated with no clinically significant side effects observed. Between baseline and the end of cycle 6, mean decreases were noted in absolute lymphocyte count from 1697 to 463 (p = 0.000012), CD4 count from 865 to 187 (p = 0.0000008), CD8 from 418 to 165 (p = 0.005) and CD19 from 197 to 26 (p = 0.000002). Platelet, granulocyte and RBC counts were unaffected. Approximately one year after completion of therapy, some recovery of CD4 and CD8 counts had occurred although both counts remained suppressed compared to baseline (302 and 227 respectively); the CD19 count had recovered essentially to normal by one year. EDSS scores post-therapy revealed some deterioration in 8 patients and stable scores in the remaining 11. Global patient evaluations of the treatment were mixed. CONCLUSIONS Cladribine therapy, at lower doses than previously reported, was remarkably well tolerated in CPMS, with no significant myelosuppression. Profound effects occurred in total lymphocyte count and CD4, CD8 and CD19 subsets.

Abstract
OBJECTIVE To determine the incidence, clinical presentation, and outcome and confounding factors associated with the development of a brain abscess in solid organ transplant recipients. DESIGN A 14-year retrospective survey. SETTING A single, multiorgan, academic transplantation center. PATIENTS A total of 2380 liver transplant recipients, 1650 kidney transplant recipients, and 598 heart, heart-lung, or lung transplant recipients of all ages (pediatric and adult) were included. All patients were given cyclosporine-based immunosuppression during this period. MAIN OUTCOME MEASURE A brain abscess was determined to be present it there was histological and/or microbiological confirmation of a brain lesion seen by a computed tomographic scan. A brain abscess was considered suspicious if radiographic findings were seen in the clinical setting of neurologic symptoms and fever without histological or microbiological confirmation. RESULTS A brain abscess developed in a total of 28 patients (0.61%) of the total study population. The frequency of brain abscess according to organ type was as follows: 0.63%, liver; 0.36%, kidney; and 1.17%, heart and heart-lung. The overall mortality was 86%. Complicating factors associated with fungal (Candida and Aspergillus sp) abscess formation included major subsequent operations, retransplantations, antirejection therapy, associated bacteremia or viremia, and multiorgan failure. The lung was the primary site of dissemination in 18 patients. Low-dose prophylactic amphotericin was ineffective in preventing a fungal brain abscess in 10 high-risk patients. Because of the ineffective therapy and the deadly nature of established fungal abscesses, full-dose antifungal therapy and reduced immunosuppression were warranted on identification of a high-risk clinical setting. Nonfungal abscesses (Nocardia and Toxoplasma sp) occurred in healthy graft recipients long after transplantation. The existing medical therapy is usually effective in these patients, provided that rapid tissue diagnosis is established. CONCLUSIONS The epidemiological features of brain abscess formation after solid organ transplantation suggest 2 populations of patients exist that differ in timing, clinical setting, and response to therapy. For the chronically immunosuppressed outpatient, an established abscess should be empirically treated with sulfonamides until tissue diagnosis is confirmed. On the other hand, the acutely immunosuppressed posttransplant recipient, with defined risk factors, should receive full-dose therapy with amphotericin B and concomitantly lowered immunosuppression.

Abstract
We report the clinical features in 27 Australasian patients with Angelman syndrome (AS), all with a DNA deletion involving chromosome 15(q11-13), spanning markers from D15S9 to D15S12, about 3 center dot 5 Mb of DNA. There were nine males and 18 females. All cases were sporadic. The mean age at last review (end of 1994) was 11 center dot 2 years (range 3 to 34 years). All patients were ataxic, severely retarded, and lacking recognisable speech. In all patients, head circumference (HC) at birth was normal but skewed in distribution, with 62 center dot 5% at the 10th centile. At last review HC was around the 50th centile in three patients (12 center dot 5%) while 15 had poor postnatal head growth. Short stature was not invariable, 5/26 (19%) were on or above the 50th centile. Hypotonia at birth was recorded in 15/24 (63%) and neonatal feeding difficulties were recorded in 20/26 (77%). Epilepsy was present in 26/27 (96%) with onset by the third year of life in 20 patients (83%). Improvement in epilepsy was reported in 11/16 patients (69%) with age. An abnormal EEG was reported in 25/25 patients. Hypopigmentation was present in 19/26 (73%). One patient had oculocutaneous albinism. Five patients could not walk independently. Of the remaining 22 who could walk, age of onset of walking ranged from 2 to 8 years. Disrupted sleep patterns were present in 18/21 patients (86%), with improvement in 9/12 patients (75%) over 10 years of age. The clinical features in this group of deletional AS patients were similar to previous reports, but these have not separated patients into subgroups based on DNA studies. In our group of deletional cases, 100% showed severe mental retardation, ataxic movements, absent language, abnormal EEG, happy disposition (noted in infancy in 95%), normal birth weight and head circumference at birth, and a large, wide mouth. These features occurred with a higher frequency than in AS patients as a whole. Our study also provided information on the evolution of the phenotype. The data can act as a benchmark for comparisons of AS resulting from other genetic mechanisms.

Abstract
PURPOSE More than 900 patients who underwent hepatic resections were reviewed to identify those whose liver resections were due to involvement by renal cell carcinoma. MATERIALS AND METHODS Three patients with direct hepatic extension of the renal cell cancer underwent radical nephrectomy with en bloc partial hepatectomy, while 1 with a metachronous recurrence 3 years after nephrectomy underwent right triple lobe hepatectomy. There were no postoperative complications. RESULTS Of the en bloc resections 2 showed sarcomatoid features on histopathological examination. These patients experienced rapid disease progression and died. The remaining 2 patients with typical clear cell carcinoma have no evidence of disease. CONCLUSIONS Experience with these 4 patients has demonstrated that hepatic resection is technically feasible and associated with acceptable morbidity rates. Surgical management should be considered in patients with the uncommon presentation of renal cell carcinoma and localized hepatic involvement.

Abstract
OBJECTIVE To evaluate the frequency and outcome of liver transplantation for symptomatic, unresectable, benign hepatic neoplasms. DESIGN Retrospective study. SETTING Presbyterian University Hospital, a tertiary care referral center for liver transplantation affiliated with the University of Pittsburgh (Pa). PATIENTS All 3239 liver transplant recipients at the University of Pittsburgh from January 1981 until January 1993. RESULTS Twelve (0.37%) of 3239 patients required liver transplantation for benign, highly symptomatic hepatic neoplasms that were unresectable. Origins included adenoma (n = 6), mesenchymal hamartoma (n = 2), massive hepatic lymphangiomatosis (n = 1), hilar fibrous angiodysplasia (n = 1), focal nodular hyperplasia (n = 1), and hemangioma (n = 1). There were three perioperative deaths and two late deaths at 56 and 84 months. The remaining patients are alive, with follow-up ranging from 36 to 145 months. Median survival for the nine patients who survived the perioperative period is 88 months. The early deaths were attributable to hemorrhagic complications (n = 2) and necrotizing pancreatitis (n = 1). The two late deaths were due to disseminated aspergillosis and hepatitis-associated cirrhosis. CONCLUSION Patients with severe symptoms from benign hepatic neoplasms that are not resectable can be treated by total hepatectomy and orthotopic liver transplantation, with the expectation of good long-term results.

Abstract
Total hepatectomy plus liver transplantation was performed on 105 patients considered unsuitable for liver resection. Postoperative 5-year actuarial survivals correlated with the pathologic stage of the tumor: stage I 75%, stage II 68%, stage III 52.1%, and stage IVA 11%. The overall 5-year survival for all patients was 36%. Nodal disease, bilobar tumor, and macroscopic venous invasion were significant poor-prognosis features. In addition, 12 patients with pT4N1M0 lesions (also stage IVA) had hepatectomy plus more extensive en bloc regional resection (Whipple procedure or cluster resection) plus transplantation in an effort to prevent local recurrence. Only 2 of these 12 patients (16.7%) are alive and free of disease after 2 years. Seven patients (58%) have died from tumor recurrence usually originating from distant metastases an average of 10.6 months after transplantation. Successful transplantation for hepatoma depends on screening programs to identify early stage disease. Successful outcome of transplantation for late stage disease, which includes most of the patients in our series, awaits the development of neoadjuvant therapy to control distant microscopic metastases, which are almost certainly present though not apparent at the time of transplantation.

Abstract
BACKGROUND The selection of patients for resective therapy of hepatic colorectal metastases remains controversial. A number of clinical and pathologic prognostic risk factors have been variably reported to influence survival. METHODS Between January 1981 and December 1991, 204 patients underwent curative hepatic resection for metastatic colorectal cancer. Fourteen clinical and pathologic determinants previously reported to influence outcome were examined retrospectively. This led to a proposed TNM staging system for metastatic colorectal cancer (mTNM). RESULTS No operative deaths occurred (death within 1 month). Overall 1-, 3-, and 5-year survivals were 91%, 43%, and 32%, respectively. Gender, Dukes' classification, site of primary colorectal cancer, histologic differentiation, size of metastatic tumor, and intraoperative blood transfusion requirement were not statistically significant prognostic factors (p > 0.05). Age of 60 years or more, interval of 24 months or less between colorectal and hepatic resection, four or more gross tumors, bilobar involvement, positive resection margin, lymph node involvement, and direct invasion to adjacent organs were significant poor prognostic factors (p < 0.05). In the absence of nodal disease or direct invasion, patients with unilobar solitary tumor of any size, or unilobar multiple tumors of 2 cm or smaller (stages I and II) had the highest survival rates of 93% at 1 year, 68% at 3 years, and 61% at 5 years. Unilobar disease with multiple lesions greater than 2 cm (stage III) resulted in 1-, 3-, and 5-year survivals of 98%, 45%, and 28%, respectively. Patients with bilobar involvement (multiple tumors, any size, or a single large metastasis) (stage IVA) had survival rates of 88% at 1 year, 28% at 3 years, and 20% at 5 years (p < 0.00001). Patients with nodal involvement or extrahepatic disease (stage IVB) experienced the poorest outcome with 1-, 3-, and 5-year survivals of 80%, 12%, and 0%, respectively (p < 0.00001). CONCLUSIONS The proposed mTNM staging system appears to be useful in predicting the outcomes after hepatic resection of metastatic colorectal tumors.

Abstract
OBJECTIVE The efficacy for primary orthotopic liver transplantation of a new immunosuppressive agent, FK 506 (tacrolimus, Prograf, Fujisawa USA, Deerfield, IL), was determined. SUMMARY BACKGROUND DATA After 3 years of preclinical research, a clinical trial of FK 506 for orthotopic liver transplantation was begun in February 1989, first as a rescue therapy for patients with intractable rejection with conventional immunosuppression, then as a primary drug. METHODS Between August 1989 and December 1993, 1391 recipients (1188 adult and 203 pediatric) of primary liver allografts were treated with FK 506 from the outset. Results from these patients were analyzed and compared with those of 1212 historical control patients (971 adult and 241 pediatric) given cyclosporine-based immunosuppression. RESULTS Actuarial survival at 4 years was 86.2% with FK 506 versus 65.5% with cyclosporine in the pediatric patients (p < 0.0000) and 71.4% versus 65.5% in the adults (p < 0.0005). The need for retransplantation was reduced significantly for FK 506 patients. Four-year graft survival was 77.0% with FK 506 versus 48.4% with cyclosporine in the pediatric patients (p < 0.0000), and 61.9% with FK 506 versus 51.4% with cyclosporine in the adult recipients (p < 0.0000). Regression analysis revealed that reduction in mortality or graft loss from uncontrollable rejection, sepsis, technical failure, and recurrent original liver disease were responsible for the improved results with FK 506 therapy. CONCLUSIONS FK 506 is a potent and superior immunosuppressive agent for orthotopic liver transplantation.

Abstract
BACKGROUND Complete reports of biliary and vascular injuries after laparoscopic cholecystectomy are rare. STUDY DESIGN Fifteen patients with complex laparoscopic cholecystectomy injuries underwent corrective operations. The injuries consisted of 14 bile duct injuries and one large laceration of a cirrhotic liver. Five of the bile duct injuries were accompanied by inadvertent occlusion of the right hepatic artery, and one was further complicated by portal vein occlusion. One hepatic artery occlusion and one portal vein occlusion were successfully reconstructed. Two patients with arterial occlusion required right hepatic lobectomy. Corrective biliary operations consisted of common hepaticojejunostomy (seven cases), right and left hepaticojejunostomies (one case), right anterior and left hepaticojejunostomies (two cases), right hepaticojejunostomy (one case), right posterior hepaticojejunostomy (one case), and left hepaticojejunostomy after right lobectomy (two cases). RESULTS Except for a patient with a severe laceration of a cirrhotic liver who died as a result of hepatic failure, the remaining 14 patients are alive and well with normal hepatic function tests at six and 37 months after corrective operations. CONCLUSIONS A knowledge of anatomy is critical to the prevention of injuries to the hepatobiliary tree and related structures during laparoscopic cholecystectomy.

Abstract
AIMS To assess the impact, mortality, morbidity and economic costs, of respiratory distress syndrome severe enough to warrant ventilation in one year in New Zealand. METHODS Review of data from all five New Zealand regional neonatal intensive care units' participation in the international OSIRIS trial of exogenous surfactant (Exosurf) treatment for respiratory distress syndrome (involving 6700 infants in 21 countries), and extrapolation of these data to a full year. RESULTS There were 265 New Zealand infants entered in the OSIRIS trial; the mean birthweight was 1335 g and mean gestation 29 weeks; 61% of infants were less than 30 weeks gestation. Forty-seven infants (17.7%) died prior to discharge from hospital, 40 deaths being attributed to prematurity or respiratory distress syndrome. One hundred and two infants (38.5% of the cohort; 45% of surviving infants) were oxygen dependent and 36 infants (13.6%) were dead at 28 days of age. Thirty-four infants (12.8% of the cohort; 15% of surviving infants) were oxygen dependent and 40 infants (15%) were dead at the expected date of delivery. Infants were intubated for a mean 12.5 days, with surviving infants of less than 27 weeks gestation intubated for a disproportionately long period of time. Seventy-two infants (29% of the 246 infants examined) had an abnormality detected by cranial ultrasound scan at 1 or 6 weeks of age and in 23 (9%) this was a major abnormality. Of surviving infants 16 (7.5% of 213 examined) had a major abnormality on cranial ultrasound scan. Amongst infants at high risk for respiratory distress syndrome (gestation less than 30 weeks) 53% received antenatal steroids, compared with 22% in the OSIRIS trial overall. In a full year the cost of caring for infants with respiratory distress syndrome sufficiently severe enough to warrant ventilation is estimated to be NZ$12.5 million. The average cost of caring for a surviving infant was roughly NZ$52,500 and a nonsurviving infant was NZ$24,500. CONCLUSIONS In a full year (total births 60,000) approximately 350 New Zealand infants may require ventilation for respiratory distress syndrome. Increasing the percentage of infants who receive antenatal steroids is likely to be extremely cost effective. In the era of antenatal steroids and exogenous surfactant, 85% of infants with respiratory distress syndrome requiring ventilation survive to discharge home and over 90% of survivors are likely to be healthy normal adults.

Abstract
Our procedure for donor harvesting and preserving intestinal grafts has matured. In 27 consecutive cases, a protocol was established whose essentials consist of (a) selecting hemodynamically stable donors, (b) antibiotic pretreatment of the donor, and (c) short warm ischemic times (< 40 minutes). Assessment of graft quality can be achieved by daily inspection of stomas, inspection for diarrhea > 2.5 1/day in adults or > 300 ml in children, and weekly protocol or clinically directed endoscopic biopsies. Edema and microscopic separation of the mucosal surface and sloughing are routinely found during the first few post-engraftment days, but the crypt cells remain and regenerate a normal mucosa within a week. Recovery of a normal mucosal surface took place in all cases.

Abstract
OBJECTIVE The purpose of this study was to report the authors' experience with hepatic resection for cystic lesions of the liver. SUMMARY BACKGROUND DATA Past experience with aspiration, sclerosing therapy, internal drainage, fenestration, and marsupialization are of limited value. Hepatic resection has evolved into a safe operation over the last two decades. METHODS A retrospective study of 44 patients with various cystic lesions of the liver (polycystic disease, 2; solitary or multiple congenital cysts, 19; biliary cystadenoma, 6; cystadenocarcinoma, 3; squamous cell carcinoma, 3; Caroli's disease, 5; and hydatid cyst, 6) was performed. RESULTS After 7 trisegmentectomies, 24 lobectomies, 6 left lateral segmentectomies, and 7 nonanatomical hepatic resections, only 1 operative death occurred in a Jehovah's Witness. Symptomatic relief was complete and permanent in all of the patients with benign congenital or parasitic hepatic cysts, except for the two patients with polycystic disease of the liver. One of the 3 patients with adenocarcinoma and 3 patients with squamous cell carcinoma of the cyst wall died of tumor recurrence between 3 and 14 months after hepatic resection. CONCLUSIONS Hepatic resection is safe and effective for cystic lesions of the liver. Symptomatic relief is complete and permanent after hepatic resection, except in cases of diffuse polycystic disease of the liver. Liver transplantation should be considered for diffuse polycystic disease of the liver when the symptoms are extremely severe.

Abstract
Intestinal transplantation, solitary (n = 3) or in combination with the liver (n = 7), was performed in 10 pediatric patients with intestinal failure. The liver was only replaced if there was liver failure and portal hypertension. Immunosuppression was based on FK 506. Two patients died, one of graft-versus-host disease and one of lymphoproliferative disease. One patient as still in the intensive care unit 1 month posttransplantation due to perioperative complications. The function of the intestinal grafts in the remaining patients is normal. All nutrition and medications including immunosuppression are being administered enterally. This series indicates that small bowel transplantation, alone or in combination with the liver, is feasible in pediatric patients.
