The aim of this study was to analyze the 20 years experience of the Renal Transplantation Center in Katowice in which 681 kidney transplants in 678 patients were performed between March 1983 and December 2000. Several parameters have been analyzed in this group: HLA class I and class II antigens compatibility, the mean cold ischaemia time, time to restore renal function, recipient's mortality, the causes of recipients' death, the early post-transplant complications, and patients' and grafts' survival. In the analyzed period of time HLA matching improved significantly (the median number of matched antigens of class I and II increased from 1 to 3) and the mean cold ischaemia time decreased from 27 to 20 hours. The number of transplants with early graft function increased from 9.5 to 42% and the number of primary non-functioning grafts decreased from 16 to 9%. Also recipients' early mortality declined significantly (from 31 to 5.5%). Among early post-transplant complications cases with sepsis and gastrointestinal bleeding decreased significantly. Improvement of both one-year and five-years graft survival was observed. During the observation period the number of donors did not changed and the rate of living kidney donors remained very low (1.76% of all transplants).

Liver transplantation is the treatment of choice in selected patients with end-stage liver disease. Postoperative complications often require surgical re-intervention. This study is a retrospective single-centre study to assess the incidence and type of surgical re-intervention during the in-hospital period after liver transplantation and to identify predictors of this re-intervention. From 1994 to 2002, 231 consecutive adult liver transplantations were performed. Re-intervention was classified as biliary, vascular, bleeding, septicaemia, re-transplantation or as miscellaneous. One hundred and thirty-nine surgical re-interventions were performed in 79 of 231 patients (34%). Septicaemia (44%) and bleeding (27%) were the most frequent indications for re-intervention, followed by biliary (10%) re-intervention. Vascular re-intervention, re-transplantation, and re-intervention for miscellaneous reasons, were performed in 7% each. Of all analysed variables (gender, age, diagnosis, acute liver failure, Child-Pugh classification, Karnofsky score, previous abdominal surgery, creatinine clearance, prothrombin time, anti-thrombin, platelet count, surgical technique, cold ischaemia time, warm ischaemia time, functional anhepatic time, anatomic anhepatic time, revascularisation time, year of transplantation, aprotinin administration, transfused platelet concentrate, and red blood cell transfusion requirements), only the number of transfused red blood cell concentrates (RBCs) was identified as a predictor of surgical re-intervention. Median RBC transfusion requirement during liver transplantation was 2.9 l (range 0-18.8 l) in the re-intervention group compared with 1.5 l (range 0-13.4 l) in the non-re-intervention group (P<0.001). This study revealed intraoperative blood loss as the main determinant of early surgical re-intervention after liver transplantation and emphasises the need for further attempts to control blood loss during liver transplantation.

Persistent pulmonary hypertension of the newborn (PPHN), among the most rapidly progressive and potentially fatal of vasculopathies, is a disorder of vascular transition from fetal to neonatal circulation, manifesting as hypoxemic respiratory failure. PPHN represents a common pathway of vascular injury activated by numerous perinatal stresses: hypoxia, hypoglycemia, cold stress, sepsis, and direct lung injury. As with other multifactorial diseases, a single inciting event may be augmented by multiple concurrent/subsequent phenomena that result in differing courses of disease progression. I review the various mechanisms of vascular injury involved in neonatal pulmonary hypertension: endothelial dysfunction, inflammation, hypoxia, and mechanical strain, in the context of downstream effects on pulmonary vascular endothelial-myocyte interactions and myocyte phenotypic plasticity.

Between 1989 and 2003, 100 transplants were performed in 96 patients at the pediatric nephrology unit of the Calvo Mackenna Children's Hospital. Mean age 10.9 +/- 3.9 yr (1-17.6), 30% from LD. Donors were younger than 5 yr in five patients and all recipients received an 'en bloc' graft. Original disease was hypo/dysplasia 27%, reflux nephropathy 22 and 17% chronic glomerulonephritis. The immunosuppressive protocol during the first period (n = 56, 1989-2000): Cyclosporine, steroids and azathioprine, and during the second period (n = 44, 2001-2003): FK, steroids, MMF and anti-CD25 antibody (mAbs). AR was reported in 22 patients, 11% in LD, 31% in DD (p < 0.01). The AR rate decreased from 40 to 8% after anti-CD25 monoclonal induction. Patient actuarial survival rate at 1, 3 and 5 yr was 100% for LD and 96% for DD. The overall actuarial graft survival at 1,3, and 5 yr was 96.7, 96.7 and 71% for LD and 89, 76 and 73% for DD donors. Graft survival rate improved from the first period (1989-2000) to the second period (2001-2003; p = 0.05). No difference in graft survival rate with HLA-A,B,DR matching was found. Graft survival rate was better when cold ischemia time was <24 h (p < 0.01). CMV infections increased from 19 to 40% when MMF and anti-CD25 Ab were introduced (p < 0.01). The height/age Z score at 1, 3 and 5 yr post-transplant was -2.2, -2.1, -2.2, respectively, for children older than 7 yr and -1.8, -1.9, -2.1 for those transplanted younger than 7 yr of age who were switched to alternate day steroids (p < 0.01). The cause of graft lost was: chronic rejection eight, non-adherence four, AR four and vascular thrombosis two. The cause of death in two patients was fungus septicemia and accelerated rejection. Pediatric renal transplantation can be performed in our group with acceptable morbidity, low mortality and graft survival rates similar to other reports in North America and Western Europe. Graft survival rate improved with newer immunosuppression and greater experience at the center. Management of non-adherence and chronic rejection remain the major challenges.

Retransplantation (re-TX) is the only available therapy for irreversible liver graft dysfunction. The outcome of a second procedure depends upon several factors, some of which are not defined at the time of the decision to retransplant. This study is an analysis of all re-TX of the liver performed at our unit between January 1995 and January 2004. Among the 474 liver TX were 55 (11.6%) re-TX in 47 patients. We studied (1) diagnosis at first TX; (2) indication for re-TX and time lapse; (3) donor age and cold ischemia time (CIT); (4) duration of operation, peroperative bleeding, and complications; (5) ICU and ward periods; and (6) patient and graft survivals. Patients who underwent re-TX did not differ from those transplanted once with regard to age, gender, or diagnosis. The indications for re-TX were roughly one-third biliary tract complications/chronic rejection, one-third hepatic artery thrombosis, and one-third others, including primary nonfunction, acute rejection, portal vein thrombosis, sepsis, and B/C hepatitis. The re-TX were "urgent" in 29 and "elective" in 26 cases. Complications were common; about half of the patients were reoperated due to bleeding or biliary problems. To date (May 2004), 15 patients have died (12 "urgent" and 3 "elective"), of whom 5 had well functioning grafts. In summary, liver re-TX is a complicated procedure associated with significant mortality and morbidity, but considering that the actual patient group has a poor prognosis without re-TX, the results are nevertheless encouraging.

Although renal dysfunction is common after liver transplantation, postoperative renal function after split liver transplantation (SLT) has not been well studied. Renal function immediately after surgery was analyzed retrospectively in 16 patients that received a SLT (SLT group). The results were compared with corresponding data from 31 matched patients that received a full-size liver transplant (FSLT group) during the same period. Serum creatinine (SCr) was measured before surgery, and, after transplantation, daily during the first week and at days 14, 21, and 28. Renal dysfunction (RD) was defined as the requirement for renal replacement therapy (RRT) or a 100% increase in SCr if the basal value had been <1.0 mg/dL or a 50% increase in SCr if the basal value had been >1.0 mg/dL. SCr had to be at least 1.5 mg/dL for a diagnosis of RD to be considered. The classification of RD was: mild, SCr 1.5-2.4 mg/dL; moderate, SCr 2.5-4.0 mg/dL; or severe, SCr >4.0 mg/dL (the requirement for RRT). Both donor and recipient age and cold ischemia time were lower in the SLT group than in the FSLT group (P < 0.05). Length of surgery was longer in the SLT group (P < 0.05). There were no significant differences between groups with respect to Model for End-Stage Liver Disease scores, the need for transfusions, the length of admission to the intensive care unit (ICU), survival rate, individual severity index, or sepsis-related organ failure assessment scores at the time of diagnosing RD. Immunosuppression regimens were similar in both groups. RD developed in 82% of SLT patients, but in only 58% of FSLT patients (P = not significant [NS]). Among SLT patients, RD (23.0% mild, 15.5% moderate, and 61.5% severe) was more severe (P = 0.007) than in FSLT patients (63.1% mild, 15.8% moderate, and 24.1% severe). The requirement for RRT in the SLT group (43.7%) was significantly greater (P < 0.05) than that in the FSLT group (12.9%). This finding may be due to the different incidence of sepsis in the 2 groups (SLT 37.5% vs. FSLT 9.7%; P < 0.05). In conclusion, although the number of patients studied was small, our data suggest a higher incidence of RD and a greater requirement for RRT in patients that receive a split liver graft than in those that receive a full size liver graft.

A 78-year-old woman was admitted with dyspnea. She had caught a cold and took an over-the-counter drug (Nospole G) for 2 weeks before admission. Chest radiography and CT scanning showed bilateral diffuse and interstitial shadows, and arterial blood gas analysis demonstrated severe hypoxemia. Withdrawal of Nospole and treatment with both corticosteroid and sivelestat sodium resulted in improvement of clinical findings and successful recovery from mechanical ventilation. A drug lymphocyte stimulation test for Nospole G was positive. Based on these findings, we determined that this patient had drug-induced pneumonitis caused by Nospole G. Finally, she died of sepsis caused by multidrug-resistant Staphylococcus aureus (MRSA) infection. In summary, we report here an elderly case of drug-induced pneumonitis successfully weaned from mechanical ventilation by early treatment with corticosteroid and sivelestat sodium, monitored by changes of markers for interstitial pneumonitis (KL-6, SP-A, SP-D).

The "kite-flap" is a cutaneous island flap containing a triple pedicle. It is harvested from the dorsum of the index and is intended to cover skin-loss on the thumb. The purpose of our study was to evaluate 12 "kite-flaps" performed over the course of 11 years. The skin defects were on the dorsum of the distal phalanx of the thumb in 3 cases, on the dorsum of both the distal and proximal phalanges in 4 cases and on the volar aspect of the thumb in 5 cases. The associated lesions consisted of combined bone and skin in one case treated by bone graft with external fixation, and one case of septic arthritis of the interphalangeal joint treated by arthrodesis. The results of our series are very good after an average of 2 years follow-up. We have however had 4 cases of cold intolerance, 2 cases of superficial sepsis and one case of shrinkage of the first commissure. It appears that the "kite-flap" is the best solution for cover of simple or complex skin loss of the thumb. Its technical performance is easy, and it gives durable, sensate and stable skin cover.

In a developing country such as India, cadaveric renal transplantation accounts for only less than 1% of total renal transplantations. The reasons for such a low rate of cadaveric transplantation are many, ranging from lack of awareness to socioeconomic reasons. Our institute conducted a statewide public awareness program and initiated an intercity organ harvesting program. This doubled the cadaveric renal transplantations in the last 2 years. We performed 38 cadaveric transplantations among 190 renal transplantations in the last year (August 2005 to July 2006). We retrieved kidneys from 21 donors, of whom 9 were outside our city. From 21 donors we transplanted 38 recipients; out of whom 3 received dual kidneys and one kidney was discarded. The Mean age of the donors was 41.4 +/- 18.2 years with a mean cold ischemia time of 6.9 +/- 3.8 hours. Sixty-eight percent had delayed graft function. At the last follow-up, which was 190 +/- 98 days, patient survival rate was 90%: 4 patients died, including 2 due to bacterial sepsis and 2 due to cytomegalovirus (CMV) disease. The Graft survival rate was 85%, and the death-censored graft survival rate was 90%. Mean serum creatinine value at the last follow-up was 1.2 +/- 0.3 mg%. There were 5 episodes of acute rejection in 31 patients during first 3 months (16% acute rejection rate). The increase in cadaveric transplantations was associated with satisfactory patient and graft survival despite the high incidence of delayed graft function.

KT is the most effective therapeutic option for ESRF. We present our first experiences in a developing country. All children who underwent kidney transplantation since the inception of this program in July 2004 until 30 September 2005 were studied. Their demographic data, operative and peri-operative details, graft and host survival, and drug compliance are described here. Data were collected from patient records and nursing observation records. Eleven children were transplanted during this period (median recipient age 10.75 yr, range: 8-16). The median age of the donors was 41 yr (range: 38-45) and was the mother in eight, father in two and uncle in one. The median (range) follow-up period following transplantation was 12.5 months (7-12). The vascular anastomotic site was aorta and inferior vena cava in nine patients and the cold ischemia time was mean (s.d.) 1.9 h (0.96). All patients received steroids, cyclosporine and MMF for immunosuppression. Hypotension, heart failure and septicemia were common medical complications. Four were treated for acute rejection. Vascular anastomotic leak, burst abdomen, intestinal obstruction, intra-abdominal leak of supra pubic catheter and vesico-ureteric junction obstruction were surgical complications. There were no graft losses or deaths. Despite limited resources good outcomes are possible following renal transplantation in children in developing countries.
