Comparison of peritoneal closure techniques in laparoscopic transabdominal preperitoneal inguinal hernia repair: a prospective randomized study.

PURPOSE: We aimed to compare tacker and suture techniques for peritoneal closure with respect to patient outcomes. METHODS: A total of 64 patients were included in the study, 32 being in the tacker group and 32 in the suture group. All patients underwent laparoscopic TAPP inguinal hernia repair. Both groups were compared with respect to age, sex, duration of peritoneal closure and the operation, hernia type, the number of tackers used for mesh fixation, postoperative complication rate, visual analogue scale (VAS) scores on 1st, 7th, and 30th days, duration of follow-up, and recurrence rates. RESULTS: Duration of peritoneal closure and the operation was significantly shorter in the tacker group compared to the suture group (p < 0.001, p = 0.008, respectively). Statistical analysis with the two-way analysis of variance method revealed that mesh fixation with one or two tackers did not influence postoperative pain. VAS 1 was significantly lower in patients with peritoneal closure with suture compared to the patients undergoing peritoneal closure with tacker (p = 0.027). VAS 7 and VAS 30 were lower for peritoneal closure with suture versus tacker, although the difference did not reach statistical significance (p = 0.064, p = 0.294, respectively). We observed no recurrence at an average of 21-month follow-up. CONCLUSIONS: Tacker and suture appeared to have a comparable safety for peritoneal closure in laparoscopic TAPP inguinal hernia operation. It can be suggested that peritoneal closure with tacker increased short-term pain, independent of the number of tackers used for mesh fixation. Long-term pain was similar in both groups.

MDCT evaluation of early pulmonary infection types after liver transplantation.

INTRODUCTION: Opportunistic pulmonary infections frequently occur after liver transplantation, and affect mortality and morbidity significantly. The purpose of this study was to define the incidence, types, and imaging characteristics of pulmonary infections in liver transplant recipients with multidetector CT (MDCT) evaluation. METHODS: Thirty-five adult transplant recipients diagnosed with a pulmonary infection within the first 45 days posttransplantation were reviewed retrospectively from March 2002 to December 2013. MDCT features were evaluated retrospectively by 2 radiologists in consensus. All diagnoses were made by sputum analysis, cultures, biopsies, and postmortem histopathologic evaluation. RESULTS: Pneumococcus pneumonia was found in 7 patients. Five patients had nonspecific pneumonia, Candidiasis, Klebsiella, and Aspergillosis separately. S aureus pneumonia was detected in 2 patients and the other 2 patients had Escherichia coli pneumonia. Two patients had active tuberculosis and 1 patient had Acinetobacter pneumonia also. Four main MDCT patterns were identified: patchy infiltrations (10%), tree-in-bud pattern (9.5%), ground-glass opacity (8.5%), and nodules with halo sign (6%). One patient had a cavitary lesion owing to tuberculosis. CONCLUSION: Although the incidence of pulmonary complications in liver recipients was relatively low, mortality from serious infections was high. Care must be taken with pulmonary infectious complications in the posttransplant period. For any suspicious case, MDCT evaluation for specific patterns of early accurate diagnosis is very important.

LigaSure® versus clamp tie technique for thyroid surgery; decreased operative time versus increased inflammatory effect: a prospective randomized study.

OBJECTIVE: The aim of this study was to compare the LigaSure® Small Jaw Instrument (LSJI) with the conventional clamp-and-tie (CT) technique in thyroid surgery regarding complication rates (hematoma, hypocalcemia and recurrent nerve palsy), the duration of the operative procedure, and systemic and local inflammatory effects. PATIENTS AND METHODS: Fifty-four consecutive patients were randomized prospectively into two groups, a Conventional Clamp-Tie (CT) group and a LigaSure® Vessel Sealing System (LVSS) Group. Pre- and postoperative blood plasma samples were taken to measure the tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), calcium, parathormon, CRP levels and WBC, as well as the lymphocyte subset (CD3, CD4, CD8, CD16/56, CD19) counts. The drain fluid samples were collected after the removal of the drains to measure the levels of IL-6 and TNF-α. RESULTS: Both groups showed significant changes regarding peripheral blood CD3+, CD4+, and CD8+ T cell levels (p < 0.05). In the LVSS group, the level of CD16+56+ NK cells showed a significant decrease compared with the CT group (p < 0.05). The IL-6 and TNF-α levels in the drainage fluid were significantly higher in the LVSS group. CONCLUSIONS: We demonstrated that LSJI can decrease operative time. Although the systemic inflammatory effect of LSJI remains inconclusive, the local inflammatory effect was significant, which could cause early and late postoperative problems.

Diagnosis and treatment of xanthogranulomatous cholecystitis.

BACKGROUND: The aim of this study was to review our case load of the treatment and outcomes of patients with xanthogranulomatous cholecystitis (XGC). PATIENTS AND METHODS: Data about 21 patients were reviewed retrospectively to determine age, clinical symptoms and findings, preoperative screening, operative findings, surgical history, length of hospital stay, and postoperative complications. RESULTS: There were 14 men and 7 women (mean age, 65 ± 11.3 yr). Preoperative ultrasonography of 17 patients showed a gallbladder stone in 14 patients, adenomyomatosis plus stones in 2 patients, and a polyp in 1 patient. There were 5 patients with acute cholecystitis and 16 patients with chronic cholecystitis. Gallbladder wall thickening was noted in 3 of the 12 patients who had abdominal computed tomography. Frozen section examinations were done in 5 patients. Radical cholecystectomy was done in 1 patient because of suspected carcinoma. CONCLUSIONS: It is difficult to diagnose XGC preoperatively or intraoperatively, and the definitive diagnosis depends exclusively on pathologic examination.

Early proteinuria after renal transplantation and allograft outcomes.

BACKGROUND: Proteinuria is among the major and nonspecific sign of the renal disease. It is well known that late-onset proteinuria after renal transplantation has been associated with poor allograft outcomes and with mortality. Knowledge about the impact of early proteinuria on the various outcomes is limited. We have evaluated the utility of measuring early proteinuria in the management of pediatric renal transplant recipients. METHODS: We analyzed the effect of proteinuria at 3 months of posttransplantation on allograft rejection, graft loss, and estimated glomerular filtration rate (GFR) at 3 years. Proteinuria was assessed using 24-hour urine protein excretion. Renal biopsy was performed when elevated creatinine levels were elevated during routine follow-up and an acute rejection episode was proven with biopsy. RESULTS: Sixty-seven pediatric renal transplant recipients were included to the study. Mean follow-up time after transplantation was 48.8 ± 12.1 months. Thirty-nine recipients (58%) have proteinuria >500 mg/d. The relationship could not be shown between proteinuria at posttransplant month 3 and other outcomes parameters, such as graft loss and lower estimated GFR. A significant positive correlation between acute rejection and the proteinuria at posttransplant month 3 was shown. CONCLUSION: We demonstrated that early proteinuria is a common finding in children after transplantation. Posttransplant early proteinuria cannot be used as a long-term prognostic marker of poor renal outcome. However, early proteinuria is associated with an high risk of acute rejection episodes. This would permit an opportunity for early intervention.

Results of surgical treatment of anterior abdominal wall desmoid tumours : 13 cases reviewed with literature.

BACKGROUND: We retrospectively evaluated the results of surgical treatment for anterior abdominal wall -desmoid tumours. METHODS: Records for 13 patients operated on for desmoid tumours from 1997-2013 were searched for age, gender, abdominal/pelvic surgical history, pregnancy, Gardner's syndrome, pre-operative radiological examinations, tumour size, multifocality, surgical procedure, tumour presence at surgical margins, recurrence, morbidity, and mortality. Local recurrence-free survival probabilities were estimated by the Kaplan-Meier method and stratified by various clinicopathological variables. RESULTS: There were 11 female (84,6%) and 2 male (15,4%) patients with a median age of 36 years. Seven (53,8%) -patients had previous abdominal/pelvic surgery, five (38,5%) had a history of pregnancy, and one (7,6%) had Gardner's Syndrome. Two (15,3%) patients had multifocality on their pre-operative radiological examinations. Mean tumour -diameter was 4,6 cm (SD 3,2 cm ; range 2-12 cm). After the excision of the masses in five (38,5%) patients, synthetic materials were used to close the abdominal wall defects. Two (15,3%) patients with positive surgical margins after -surgery were re-operated. Three (23%) patients required a second surgical intervention after the mass excisions were performed. Mean follow-up time was 56,7 months. Recurrence was observed in three patients during follow-up. Increased tumour size, history of previous abdominal/pelvic surgery, and the presence of multifocality had a negative effect on local recurrence-free survival. There was no mortality during follow-up. CONCLUSIONS: Desmoid tumours are characterized by high recurrence, even after proper surgical excisions. Preoperative differential diagnoses of these tumours should be done and a post-operative follow-up protocol should be followed.

Value of early diethylentriamine penta-acetic acid renograms in predicting late allograft outcomes.

BACKGROUND: Tc-99m-diethylentriamine penta-acetic acid (DTPA) renal scintigraphy is useful, noninvasive diagnostic tool for the management and follow-up of the transplanted kidney. There have not been any studies of the predictive value of DTPA renal scintigraphy for short- and long-term allograft functions. Our aim was to reveal the significance of different perfusion-uptake patterns observed on Tc-99m-DTPA renal scintigraphy for long-term graft outcomes. METHODS: We retrospectively analyzed 59 renal transplanted children (30 male and 29 female). All patients were underwent DTPA on posttransplant day 7. Perfusion- and function-related parameters of DTPA (the ratio of peak perfusion counts to plateau counts [P:PL], the ratio of counts at peak perfusion to counts at peak uptake [P:U], and glomerular filtration rate [GFR] calculated using commercially available software) were studied. The mean P:PL and P:U calculated using the half-moon-shaped background region of interest. A renal time activity curve was generated for evaluate perfusion- and function-related parameters. The patterns were classified and the value of these early DTPA parameters in predicting long-term graft function was analyzed. RESULTS: The mean age of patients was 16.69 ± 4.77 years. The mean posttransplant follow-up time was 3.5 ± 0.4 years. Thirty-nine patients received living-related donor allografts and the remaining 20 were from deceased donors. Thirteen children suffered ≥ 1 acute rejection episode. Eight patients lost their grafts during follow-up. Mean GFR value at year 3 was 80.61 ± 39.03 mL/1.73 m(2) BSA/min. There was a significant difference for mean creatinine values at year 3 between recipients with normal perfusion and function and normal P:PL with decreased P:U patterns in early DTPA (P < .05). The normal P:PL with decreased P:U pattern is associated with lowest GFR value at posttransplant year 3. There was also a significant difference for mean GFR values at year 3 between recipients with normal perfusion and function and acute tubular necrosis (P < .05). Acute rejection episodes and graft loss were mostly seen in recipient with a decreased P:PL with or without decreased P:U pattern in early DTPA. The decreased P:PL with or without decreased P:U pattern may be associated with high risk of acute rejection episodes and graft loss. CONCLUSION: Posttransplant early perfusion uptake patterns observed on Tc-99m-DTPA renal scintigraphy can be used as a long-term prognostic marker of poor renal outcomes. This would permit an opportunity for early intervention.

Neurocognitive functions in pediatric renal transplant patients.

Neurocognitive dysfunction is one of the major complications of chronic renal failure (CRF). Uremic state during CRF encompasses a wide spectrum of neurobehavioral and neurological disturbances. Recent studies showed that the pathophysiology of neurocognitive dysfunction in CRF is related to plasma levels of uremic solutes. Successful renal transplantation improves renal, metabolic, and endocrine functions and the quality of life. The aim of our study was to determine the state of neurocognitive function in pediatric renal transplant recipients. We prospectively performed a neurological examination and neuropsychological test battery (Bender-Gestalt Test, Cancellation Test, and Visual and Auditory Number Assay Test) in 20 pediatric renal transplant recipients between 6 and 16 years of age. Twenty healthy children and 20 children with CRF were included in the study as the control groups. Mean age of the renal transplant recipients was 13.50 ± 3.40 years old. Mean evaluation time after transplantation was 2.0 ± 0.5 years. Bender-Gestalt Test result was abnormal in 40% of patients. The results of the Cancellation Test and the Visual and Auditory Number Assay Test showed significant decline in pediatric renal transplant patients when compared with the control. We found that neurocognitive dysfunction was frequent in pediatric renal transplantation patients. Awareness of this potential problem may be helpful for early recognition and treatment. Our findings suggest that periodic neurocognitive assessments may be indicated in transplant recipients.

Biliary complications after pediatric liver transplantation.

OBJECTIVES: After liver transplantation, biliary complications are more prevalent in pediatric patients, with reported rates varying between 15% and 30%. METHODS: We retrospectively analyzed biliary complications observed in 84 pediatric liver transplantation patients between July 2006 and September 2012. Biliary reconstruction was accomplished via a duct-to-duct anastomosis in 5 (83.3%) of the 6 patients receiving whole liver grafts and in 44 (56.4%) of the 78 patients who received a segmental live donor graft. For the remaining 34 patients with living donor and 1 patient with whole liver graft, Roux-en-Y hepaticojejunostomy was the preferred method. RESULTS: Post-transplantation biliary complications were encountered in 26 patients (30.1%). The biliary complication rate was 38% in 49 duct-to-duct anastomosis, whereas it was 20% in the hepaticojejunostomy group consisting of 35 recipients. Thirteen of the 18 biliary leaks were from duct-to-duct anastomoses and the remaining 5 were from the hepaticojejunostomies and 6 of the 8 biliary strictures were observed in recipients with duct-to-duct anastomosis. In 19 of the 26 patients, the biliary complications were successfully treated with interventional radiologic procedures and 1 was treated with stent placement during endoscopic retrograde cholangiopancreatography. CONCLUSIONS: Percutaneous interventional procedures are valuable, effective, and life-saving therapeutic alternatives for the treatment of bile leaks and strictures after pediatric liver transplantations.

Early-onset posterior reversible encephalopathy syndrome after solid organ transplantation in pediatric patients: a report of 2 cases.

Posterior reversible encephalopathy syndrome (PRES) is a neurological disturbance that occurs due to different reasons and presents with different clinical symptoms. It can be a devastating situation, but, timely treatment may lead to complete recovery. We report 2 cases of PRES, which developed and fully recovered in the early period after solid organ transplantation in pediatric patients.

Effects of risk factors and Ki-67 on rates of recurrence on patients who have undergone liver transplant for hepatocellular carcinoma.

PURPOSE: We investigated the prognostic factors affecting recurrence including Ki-67 among patients who underwent liver transplantation for hepatocellular carcinoma. MATERIALS AND METHODS: The 50 patients with a diagnosis of hepatocellular carcinoma and cirrhosis included those with expanded criteria for hepatocellular carcinoma excluding subjects with major vascular invasion and metastases but not taking into account tumor size and number of tumor nodules. RESULTS: Twenty-eight patients had hepatocellular carcinoma characteristics outside the Milan criteria. Nineteen patients had unifocal; 31, multifocal hepatocellular carcinomas. Mean tumor size was 3.2 cm; mean tumor number was 5.06 lesions. Over a mean follow-up of 45.3±22.6 months, we diagnosed, respectively 2 recurrences. Overall 1-, 3-, and 5-year patient survival rates were 95.6%, 88.4%, and 84.8% and disease-free survival rates, 92%, 78.4%, and 71%, respectively. The independent prognostic factors by multivariate analyses were the number of tumors and Ki-67 with a cutoff value of 10%. CONCLUSION: Ki-67 staining percentage represent a marker to select recipients and to follow posttransplant recurrence.

Factors associated with hyperbilirubinemia after living donor hepatectomy.

PURPOSE: Increased serum bilirubin levels are common after living-donor hepatectomy. Little information is available on the characteristics and clinical significance of serum bilirubin levels soon after donor hepatectomy. MATERIALS AND METHODS: Since September 2001, we performed 229 living donor hepatectomies for living-donor liver transplantations. The 128 men and 101 women had a mean age of 34.4±8.9 years (range, 19-66). Most donors were parents (n=110; 48%). We transplanted 110 right lobes, 46 left lobes, and 73 left lateral segments. Donors were divided into 2 groups: Group 1 consisted of 181 donors who showed total bilirubin levels of <3 mg/dL, and group 2, 48 donors with levels of ≥3 mg/dL on postoperative day 3. Preoperative total bilirubin level, ratio of preoperatively estimated remnant liver volume, surgical duration, gender, age, graft type, blood transfusions, and preoperative liver biopsy findings were evaluated as risk factors for hyperbilirubinemia. RESULTS: The mean postoperative maximum total bilirubin level was 2.26±1.49 mg/dL (range, 0.36-9.9). Remnant liver volume<40%, preoperative bilirubin levels>1 mg/dL, right lobe donor hepatectomy, male donor, and abnormal liver biopsy findings were significant risk factors for postoperative hyperbilirubinemia (P=.015, P=.02, P<.01, P=.008, and P=.023 respectively). Also donor age>50 years showed a slight effect on hyperbilirubinemia (P=.052). Blood transfusions and surgical times were not significant factors. CONCLUSION: Donor safety is paramount, requiring thorough donor evaluation. Extensive liver resection may result in transient functional impairment. Several factors are believed to play roles in the development of postoperative hyperbilirubinemia after living-donor hepatectomy.

Comparison of basiliximab and daclizumab with triple immunosuppression in renal transplantation.

PURPOSE: Graft rejection is a serious problem despite immunosuppressive agents. Immunosuppression has been achieved with monoclonal antibodies (mAb) that bind specifically to the α subunit of the interleukin (IL)-2 receptor present on activated T lymphocytes. We explored the effects of two of the mAbs-daclizumab and basiliximab-on graft function. MATERIALS AND METHODS: Our 1543 renal transplant recipients received baseline therapy with cyclosporine or tacrolimus plus corticosteroids and mycophenolate mofetil. In addition standard dosages intravenously of daclizumab (n=156) or basiliximab (n=45) in were administered intravenously to 201 renal transplant patients who included 122 men and 79 women of overall mean age of 30±13.7 years. RESULTS: Patient and donor characteristics including age, sex, causes of renal failure, presence of comorbidities, panel-reactive antibodies, and numbers of human leukocyte antigen-mismatched were similar between the groups. During a mean follow-up of 27±20 months, biopsy-proven acute rejection was observed in three patients in the basiliximab group and 23 in the daclizumab group. Cytomegalovirus infection occurred in 13 patients. There was no case of posttransplant lymphoproliferative disorder. Three polyoma BK nephropathies were detected in the daclizumab group. No hypersensitivity reaction occurred in either group. One-year patient survival was 100% in the basiliximab group and 99% in the daclizumab group, with graft survivals of 95% versus 94%, respectively. The mean creatinine levels at discharge were 2 mg/dL versus 2.3 mg/dL and at 12 months, 1.3 mg/dL versus 1.2 mg/dL, respectively. CONCLUSIONS: Acute rejection episodes remain a significant risk factor for the development of graft dysfunction and poor long-term graft survival. IL-2R antagonists were effective antibody therapies. There was no apparent difference between basiliximab and daclizumab treatment.

Analysis of vascular complications after renal transplantation.

PURPOSE: Despite medical and surgical advances, vascular complications remain common after renal transplant, occurring among 3%-15% of patients. These complications may compromise graft function. This study sought to evaluate the frequency and management of vascular complications after renal transplant. MATERIALS AND METHODS: We retrospectively analyzed the 1843 transplantations performed at 2 centers by our team since November 1975. The 1349 male and 494 female patients had an overall mean age of 31.5±11.2 years; (range, 3-66). Grafts were obtained from a living-related donor in 1406 (76.29%) or a deceased donor in the remaining 437 (23.71%). The mean donor age was 40.7±13.7 years (range, 2-76). Of 1843 transplants, multiple vascular anastomoses were performed in 155 cases (8.4%), including 130 involving renal arteries and 25 renal veins. RESULTS: Forty-seven vascular complications (2.55%) were observed in 43 procedures (2.33%), most frequently renal artery stenosis (n=14). It was followed by allograft renal artery kinking (n=7), renal vein kinking (n=7), renal artery thrombosis (n=5), renal vein laceration (n=4), renal artery laceration (n=3), renal vein thrombosis (n=2), renal artery disruption (n=2), renal and iliac vein obstructions owing to pressure from a lymphocele (n=1), renal artery and vein obstruction owing to pressure from a hematoma (n=1), or an arteriovenous fistula after percutaneous graft biopsy (n=1). Fifteen of these 47 complications were treated by interventional radiologic procedures. CONCLUSION: The vascular complication rates in our patients were somewhat lower than those reported in the literature. A thorough understanding of how complications impair allograft function and survival is essential for adequate treatment. Interventional radiology is invaluable in the postoperative management of transplant-related complications.

Duct-to-duct biliary reconstruction without a stent in pediatric living-donor liver transplantation.

PURPOSE: In pediatric liver transplantation, Roux-en-Y hepaticojejunostomy is often preferred for biliary reconstruction, especially in living-donor liver transplantation (LDLT). Limited numbers of duct-to-duct biliary reconstructions have been presented in pediatric recipients. We retrospectively reviewed our experiences with duct-to-duct biliary reconstruction without a stent in pediatric LDLT recipients. MATERIALS AND METHODS: Since September 2006, 32 LDLTs were performed using a duct-to-duct biliary reconstruction without a stent in 31 children (16 boys and 15 girls; overall mean age, 8.3±5.1 years). We transplanted 19 left lobe grafts, 11 left lateral segments, 1 monosegment, and 1 reduced-size right lobe graft. Twenty-eight grafts had a single bile duct; the remaining 4, two bile ducts. We created a single orifice at the back table for the grafts that had 2 bile ducts. RESULTS: Two recipients developed bile leakage in the early postoperative period; 3 bile duct stenoses occurred in the late postoperative period. All biliary complications were successfully treated with interventional radiologic or endoscopic approaches. There was no morbidity and no graft loss owing to biliary complications. During a mean follow-up of 23.5±13.6 months (range, 4-44), 4 children died and the remaining 27 (88%) are doing well with satisfactory liver function. CONCLUSION: Our results showed that duct-to-duct biliary reconstruction without a stent was a safe technique for biliary reconstruction even among pediatric cases.

Diagnosis and treatment of late-onset portal vein stenosis after pediatric living-donor liver transplantation.

PURPOSE: Portal vein stenosis is a relatively rare complication after living-donor liver transplantation, which sometimes leads to a life-threatening event owing to gastrointestinal bleeding or graft failure. This study sought to evaluate the diagnoses and management of late-onset portal vein stenosis in pediatric living-donor liver transplants. MATERIALS AND METHODS: Since September 2001, we performed 123 living-donor liver transplant procedures in 120 children, among which 109 children with a functioning graft at 6 months after living-donor liver transplant are included in this analysis. Seven instances of portal vein stenosis were diagnosed and were analyzed retrospectively. RESULTS: The median age of the children was 5.3 years, and the median body weight was 19.2 kg. Portal vein stenosis was diagnosed at 11.2±3.1 months after living-donor liver transplantation. Whereas 3 children were asymptomatic, splenomegaly and/or massive ascites were observed in the remaining 4. Additionally, platelet counts were below the normal limit in 4 children. All children were treated with transhepatic balloon dilatation except 1. Intraluminal stent placement was needed in 1 child owing to resistance of balloon dilatation. The mean pressure gradient decreased from 12.4 to 3.2 mmHg after successful treatment. We did not observe any treatment-related complications. Portal venous patency was maintained in all children during posttreatment follow-up of 43.2±20.4 months. There were no recurrences of portal vein stenosis. One child died; the remaining 6 children are alive with good graft function at 49.8±23.9 months of follow-up. CONCLUSION: Although most portal vein stenosis is asymptomatic, splenomegaly and platelet counts are 2 important markers for portal vein stenosis. Early detection of portal vein stenosis with these 2 markers can lead to successful interventional percutaneous approaches and avoid graft loss.

The effect of the psychological status of breast cancer patients on the short-term clinical outcome after mastectomy.

PURPOSE: to analyze the effect of anxiety and depression on the postoperative complications and length of hospitalization of patients with breast cancer. Beck's Depression Inventory (BDI) and Hospital Anxiety and Depression Scale (HADS) were filled out by the patients pre-operatively. Patients were asked to rate their pain by the visual analogue scale (VAS) after surgery. Age, seroma volume, day of drain withdrawal, complications, and pathological stages were noted. The median age of 49 patients with the diagnosis of breast cancer was 51 (36-80). There was a significant correlation between the pain score and Beck, HADS, HADS (anxiety) and HADS (depression) (8 hours ; p = 0.021, 0.001, 0.004, 0.005 and 24 hours ; p = 0.005, 0.012, 0.006, 0.120). The mean HADS depression score in those patients with complications was 9.1 +/- 4.2 and that of patients with no complications was 6.6 +/- 3.1 (p = 0.047). The mean hospital stay of patients with a normal HADS score (< 19) was 2.9 +/- 1.1 days, whilst that of patients with an abnormal HADS score was 3.8 +/- 1.2 days (p = 0.016). Patients with abnormal HADS anxiety and abnormal HADS (total) scores had an earlier stage of breast cancer (p = 0.077, p = 0.063). The psychological status of breast cancer patients effects their postoperative recovery period and it is easy to diagnose these patients by some brief questionnaires.

Preemptive living donor renal transplantation: a single-center experience.

Renal transplantation is considered preemptive if it occurs before initiation of dialysis. In our experience and in the literature, preemptive transplantation has been shown not only to reduce the costs of renal replacement therapy but also to avoid the long-term adverse effects of dialysis. Preemptive renal transplantation therefore is associated with better survival of both the allograft and the recipient. Our aim was to evaluate the outcomes of preemptive renal transplantation experience at our center. Since 1985, 1385 renal transplantations have been performed at our center. We retrospectively analyzed the 16/1385 recipients (11 male, 5 female) of overall mean age of 28.5 +/- 15 years who underwent preemptive procedures. The causes of end-stage renal failure were focal segmental glomerulosclerosis (n = 5), vesicular ureteral reflux (n = 4), Berger disease (n = 2), polycystic renal disease (n = 2), and others (n = 3). Ten patients were adults, the remaining six, children. The mean creatinine clearance and plasma creatinine levels of the recipients before renal transplantation were 13.5 +/- 8.5 mL/min and 6.7 +/- 2.4 mg/dL, respectively. All renal transplantations were performed from living related donors. The mean preoperative serum creatinine levels, mean glomerular filtration rate, and creatinine clearance rates of the donors were 0.8 +/- 0.1 mg/dL, 61.6 +/- 6.5 mL/min, and 112.5 12 mL/min, respectively. Two episodes of acute cellular rejection and one of humoral rejection occurred during a mean follow-up of 48.7 +/- 14 months (range = 25-76 months). The two patients who experienced graft losses due to humoral rejection or chronic rejection were retransplanted 2 and 48 months thereafter, respectively. At this time all patients are alive with good renal function. In conclusion, our single-center results are promising for preemptive renal transplantation as the optimal, least-expensive mode of treatment for end-stage renal disease.

Living related liver transplantation in Crigler-Najjar syndrome type 1.

Four children underwent living related liver transplantation because of Crigler-Najjar syndrome type 1. Three were infants aged 2, 8(1/2), and 15 months, and weighed 5, 8, and 10 kg, respectively. Pretransplantation unconjugated bilirubin concentration was 22 to 30 mg/dL despite 12 to 14 hours of phototherapy daily. Patient 1, the 2-month-old infant, with unconjugated bilirubin concentration of 30 mg/dL, had a high-pitched cry, suggestive of bilirubin encephalopathy; results of neurologic examination were normal. Plasmapheresis and urgent liver transplantation were performed. Patient 4, a 13-year-old girl, had learning difficulties at school and attended a special class. Three patients received left lateral liver segments, and 1 patient received a left lobe. Biliary reconstruction was completed with duct-to-duct anastomosis. Bile leakage developed at the anastomosis in 2 patients, which was treated successfully with cholangioplasty. In all patients, the unconjugated bilirubin concentration normalized by day 1 posttransplantation, and no phototherapy was necessary. After transplantation, the 2-month-old infant with suspected encephalopathy exhibited hypotonia, spasticity of the lower extremities, and lack of head control. He died after vomitus aspiration during sleep at 10 months posttransplantation. The other 3 patients are alive with normal neurodevelopmental milestones. Irreversible brain damage may occur early in the course of Crigler-Najjar syndrome type 1. Urgent treatment including plasmapheresis, exchange transfusion, phototherapy, and liver transplantation may not reverse brain damage. Young infants must be evaluated carefully for subtle signs and symptoms of bilirubin encephalopathy. Liver transplantation is curative if performed before development of neurologic dysfunction.

The role of valacyclovir on Epstein-Barr virus viral loads in pediatric liver transplantation patients.

INTRODUCTION: Epstein-Barr virus (EBV) infection occurring in the postoperative period represents a significant risk for pediatric transplant recipients. It presents in various manners, including a mononucleosis-like syndrome, hepatitis, encephalopathy, or posttransplant lymphoproliferative disease (PTLD). Valacyclovir has in vitro activity against EBV. We sought to review our experience with valacyclovir on peripheral blood EBV viral loads among a group of EBV-infected patients after liver transplantation (OLT). PATIENTS AND METHODS: Twelve children of ages 6-36 months (median, 12 months), underwent OLT. Eight (66%) were EBV immunoglobulin (Ig)G seronegative at the time of the operation. Eight patients developed primary infection and 4 patients developed reactivation of a post primary infection. Valacyclovir was prescribed immediately to 3 patients when we detected an acute-primary EBV infection. Valacyclovir was prescribed for 2 patients who had primary EBV infections followed by PTLD. Three patients who had primary EBV infection were administered valacyclovir after they became chronically EBV PCR positive for more than 1 year. Four out of 12 cases (33%) were EBV seropositive at the time of OLT, and underwent postprimary EBV reactivation displaying chronic EBV carrier state for 8-10 months before valacyclovir treatment. Peripheral blood EBV viral loads were tested every 2 months. The primary outcome was the proportion of subjects with EBV viremia who had a >or=2 log 10 decrease in EBV copies/mL after valacyclovir treatment. The duration of valacyclovir treatment was a median of 10 months (range, 8-11 months). At the beginning of the treatment period the median level of EBV viral load was 1.1 x 10(4) (range, 1 x 10(4) to 1 x 10(7)). EBV virus was cleared in only 1 patient with primary acute EBV infection. EBV viral loads did not change in 7 of 12 patients and decreased only 1 log 10 (n = 2) or 2 log 10 (n = 2). CONCLUSION: In this small, non-placebo-controlled study, valacyclovir treatment was not effective to decrease peripheral blood EBV viral loads.
