ABSTRACT
Combined liver-kidney transplantation (CLKT) is a rare procedure in pediatric patients in which liver and kidney from 1 donor are transplanted to a recipient during a single operation. The aim of our study was to analyze indications and results of CLKT in children. MATERIALS AND METHODS: Between 1990 and 2017 we performed 722 liver transplantations in children; we performed 920 kidney transplantations in children since 1984. Among them, 25 received CLKT. Primary diagnosis was fibro-polycystic liver and kidney disease in 17 patients, primary hyperoxaluria type 1 in 6 patients, and atypical hemolytic uremic syndrome-related renal failure in 2 children. Age of patients at CLKT was 3 to 23 years (median 16 years) and body mass was 11 to 55 kg (median 35.5kg). All patients received whole liver graft. Kidney graft was transplanted after liver reperfusion before biliary anastomosis. Cold ischemia time was 5.5 to 13.3 hours (median 9.4 hours) for liver transplants and 7.3 to 15 hours (median 10.4 hours) for kidney transplants. In 8 patients X-match was positive. We analyzed posttransplant (Tx) course and late results in our group of pediatric recipients of combined grafts. RESULTS: Tx follow-up ranged from 1.5 to 17 years (median 4.5 years). Two patients died: 1 patient with oxalosis lost renal graft and died 2.6 years after Tx due to complications of long-term dialysis, and 1 died due to massive bleeding in early postoperative period. Twelve patients were transferred under the care of adult transplantation centers. Six patients were dialyzed after CLKT due to acute tubular necrosis, and time of kidney function recovery was 10 to 27 days in these patients. In 1 patient with aHUS, renal function did not recover. In children with oxalosis, hemodialysis was performed for 1 month after Tx as a standard, with the aim to remove accumulated oxalate. Primary immunosuppression consisted of daclizumab or basiliximab, tacrolimus, mycophenolate mofetil, and steroids. Acute rejection occurred in 4 liver and 3 kidney grafts. One patient required liver retransplantation due to hepatitis C virus recurrence and 2 patients required kidney retransplantation. Two patients required dialysis. CONCLUSIONS: CLKT in children results in low rate of rejection and high rate of patient and graft survival.

BACKGROUND: Among many factors predisposing to monosymptomatic enuresis (MNE) disturbances in urinary electrolites excretion play an important role. Because of many controversies in this field there is a need to debate the role of hypercalciuria in MNE. The aim of our study was to determine the urinary calcium in children with MNE. METHODS: The investigation was conducted on 204 children (83 MNE children and 121 reference group). Urinary calcium excretion (in 24-h collection and per kg of body mass), Ca/creatinine ratio, Ca(2+) in urine sample and in 24-h collection of urine were estimated. RESULTS: Hypercalciuria in MNE group was diagnosed in 18/83 (21.69%) patients. We found statistically significant differences between children with MNE in Ca(2+) in urine sample and 24-h collection and Ca/creat. ratio. Median urinary calcium excretion (mg/kg/24-h and mmol/24-h) was significantly higher in hypercalciuric enuretic patients. The urinary total calcium (mmol/24-h), urinary bound calcium and urinary calcium concentration (mmol/L) demonstrated a significant positive correlation with height, weight and age in reference group but not in MNE group. CONCLUSION: Urinary calcium excretion was significantly disturbed and further studies are needed to assess the role of hypercalciuria in the pathogenesis of MNE.

HCC constitutes 25-30% of primary malignant liver tumors in children. Conventional surgical excision is not possible in more than 50% of patients. LTx has recently become an important therapeutic option for adults and children with primary liver tumors. The aim of this study was a retrospective analysis of the clinical and pathological data of children with HCC treated with LTx in relation to Milan criteria assessed at diagnosis and then immediately before transplantation, in comparison with a group of patients treated conventionally. Between 1990 and 2007 we have treated 21 children diagnosed with HCC. Patients were divided into two groups: group I, 10 children treated conventionally and group II, 11 children treated with LTx regardless of previous therapy. The outcome of our patients treated conventionally with resection and chemotherapy is very poor--the disease-free survival rate is 30%. In contrast, despite that only 3 children having fulfilled adult Milan criteria, early clinical results of LTx are much superior. Total hepatectomy followed by LTx is the main treatment option for the majority of children with HCC. Decisions on the type of surgical treatment is made individually, but very early in the course of treatment.

New noninvasive imaging methods are very effective in the detection and differentiation of anatomic characteristics and accompanying symptoms observed in the course of the Hellp syndrome. Within the clinical picture presented the evidence of brain injury as a result of intravascular coagulopathy was predominant. CT confirmed the presence of brain lesions.

Embolization of internal iliac arteries was performed in a patient with haemorrhage from advanced uterine cervix cancer. Apart from surgical ligation of arteries, embolization is sometimes the only form of palliative treatment which in many cases improves the general condition of patients and allows continuation anticancer management. As it diminishes the fear of recurrent haemorrhages embolization significantly improves also the psychological state of patients.
