Certain magnetic fields (MF) have potential therapeutic antitumor effect whereas the underlying mechanism remains undefined. In this study, a well-characterized MF was applied to two common childhood malignancies, nephroblastoma and neuroblastoma. This MF has a time-averaged total intensity of 5.1 militesla (mT), and was generated as a superimposition of a static and an extremely low frequency (ELF) MF in 50 Hertz (Hz). In nephroblastoma and neuroblastoma cell lines including G401, CHLA255, and N2a, after MF exposure of 2 h per day, the cell viability decreased significantly after 2 days...

BACKGROUND: To reduce long-term morbidity (adhesions-related complications and impaired quality of life due to scars), laparoscopy has been used as an alternative to open surgery in Wilms tumours (WTs). However, concerns have been raised on the risk of local recurrence after this type of resection. OBJECTIVE: The aim was to determine the incidence of local recurrence after laparoscopic transperitoneal radical nephrectomy (LTRN). STUDY DESIGN: We analysed 18 local cases and conducted a review of the English literature in Pubmed from 2004 to 2017 with the following keywords: (Wilms OR nephroblastoma) AND (laparoscopy OR minimally invasive surgery) AND 2004:3000...

Standard of care for unilateral nephroblastoma includes total nephrectomy (TN) with nodal sampling. We sought to compare the outcomes of TN and partial nephrectomy (PN). We performed a retrospective cohort study of TN and PN for nephroblastoma using the National Cancer Data Base. The outcomes included nodal sampling frequency, margin status, and survival. Categorical and continuous data were evaluated with χ2 and t tests, respectively (P < 0.05). Generalized linear models evaluated nodal sampling and margin status...

Abdominal distention occurred at an incidence of 1% (15 from 1500 fish) in the population of 1-year-old bester (Huso huso × Acipenser ruthenus). Computed tomography (CT) images and radiographs showed a soft tissue mass compressed the posterior part of the swim bladder. Ultrasonography showed that the masses had different patterns. Internal examination revealed the abdominal cavities to be filled with large masses which appeared to encompass most of the visceral organs, including the swim bladder. The masses originated from the posterior kidney...

BACKGROUND: The polymalformative syndromes and craniofacial anomalies association is a well-known phenomenon in patients with Crouzon's, Pfeiffer, Apert or Muenke disease. Recently, other less frequent pathologies, such as Alagille syndrome, are showing an association with alterations in the development of cranial sutures resulting in serious cosmetic defects and neurological disorders. CASE DESCRIPTION: The authors report an exceptional case of a 30-month-old girl, nephroblastoma survivor, diagnosed with Alagille syndrome who is referred to our department with progressive anterior plagiocephaly and premature left coronal suture closure associated with a large compensating right bossing...

Nephroblastomas are uncommon embryonal tumors in dogs. We report herein a blastema-predominant nephroblastoma with gingival metastasis in an 8-y-old Miniature Pinscher dog. Histologically, the mass was composed mainly of blastemal elements with minor epithelial and mesenchymal differentiation. Metastatic masses in the gingiva had histologic and immunohistochemical features similar to those of the primary renal nephroblastoma. Neoplastic cells were extensively positive for both vimentin and PAX8, and scattered positive for cytokeratin...

A 3-year-old Japanese girl treated for hypoplastic left heart syndrome and Dandy-Walker syndrome was diagnosed with Kabuki syndrome (KS) with a mutation of KMT2D; c.13285C>T:p.Q4429*. Concurrently, macrohematuria portended the diagnosis of Wilms tumor. Postoperative chemotherapy has achieved complete remission despite a prolonged and reduced regimen due to liver dysfunction and convulsions. Cancer predisposition has been suggested for KS due to oncogenic mutations in KMT2D or KDM6A. The first case of nephroblastoma exemplified the treatability of malignancies in KS patients, as shown in the 9 cases reviewed...

BACKGROUND: Adult Wilms tumor (WT, nephroblastoma) is a rare, but well-described renal neoplasm. Although inferior vena cava tumor thrombosis is present in up to 10% of Wilms tumors in childhood, only few cases of this clinical manifestation in adults have been reported. To the best of our knowledge, this is the first case of adult WT infiltrating into inferior vena cava (IVC) with concomitant distal deep vein thrombosis. CASE PRESENTATION: A 28-year-old male patient with gross hematuria and right flank pain was diagnosed with right kidney tumor penetrating to IVC...

BACKGROUND: Short-lasting hyperglycaemia occurs frequently in prediabetes and poorly controlled diabetes mellitus leading to vascular damage. Pituitary adenylate cyclase-activating polypeptide (PACAP) has been shown to play a protective role in vascular complications of diabetes; moreover, antioxidant effects of PACAP were also described. Therefore, we hypothesized that PACAP exerts protective effects in short-term hyperglycaemia-induced vascular dysfunctions. METHODS: After short-term hyperglycaemia, acetylcholine-induced and sodium nitroprusside-induced vascular relaxation of mouse carotid arteries were tested with a myograph with or without the presence of PACAP or superoxide dismutase...

BACKGROUND: Kidney autotransplantation (KAT) is the ultimate approach for nephron-sparing surgery. It is a rarely used method in renal tumor surgery today as minimal invasive and open techniques for nephron-sparing surgery improve constantly. In this publication, the complication rate and the long-term functional and oncological outcome at a single center are analyzed. METHODS: A prospectively constructed database of patients with renal tumors who underwent renal surgery was retrospectively analyzed to identify patients with KAT and describe surgical and oncological outcomes and to obtain long-term follow-up...

A 1-year-old male American pit bull terrier was presented with a history of proprioceptive deficits and mild lameness of the right hindlimb, which progressed after 5 months to paraparesis, culminating in tetraparesis after 2 weeks. Necropsy findings were limited to the spinal cord and consisted of multiple, intradural, extramedullary, slightly red masses which produced segmental areas of medullary swelling located in the cervical intumescence, thoracolumbar column, sacral segment and cauda equina. Histological evaluation revealed a tumour, composed of epithelial, stromal and blastemal cells, with structures resembling tubules, acini and embryonic glomeruli...

Background: Multicystic renal tumors which include cystic nephroma, cystic partially differentiated nephroblastoma (CPDN) and cystic Wilms tumor has been a diagnostic and therapeutic challenge. Histopathological examination has been the only reliable differentiating method. Management of these tumors is still riddled with controversy as a definitive preoperative differentiation between the three has not been possible. Methods: A retrospective evaluation was performed of the treatment strategies employed with nine cases of multicystic renal tumors treated from 2005 to 2015...

BACKGROUND: Nephroblastoma or Wilms tumor is the most frequent kidney cancer in children and accounts for 98% of kidney tumors in this age group. Despite favorable prognosis, a subgroup of these patients progresses to recurrence and death. The retinoic acid (RA) pathway plays a role in the chemoprevention and treatment of tumors due to its effects on cell differentiation and its antiproliferative, anti-oxidant, and pro-apoptotic activities. Reports describe abnormal cellular retinoic acid-binding protein 2 (CRABP2) expression in neoplasms and its correlation with prognostic factors and clinical and pathological characteristics...

Lung immaturity is the major cause of morbidity and mortality in premature infants, especially those born <28 weeks of gestation. These infants are at high risk of developing respiratory distress syndrome (RDS), a lung disease caused by insufficient surfactant production and immaturity of saccular/alveolar type II epithelial cells in the lung. RDS treatment includes oxygen and respiratory support that improve survival but also increase the risk for bronchopulmonary dysplasia (BPD), a chronic lung disease characterized by arrested alveolarization, airway hyperreactivity, and pulmonary hypertension...

The overall survival of children with solid tumors has shown a substantial increase in the past decades due to progress in all of the disciplines involved in the treatment. The poor prognosis for advanced stages of disease and the morbidity related to therapeutic procedures are still a challenge. Innovations in the surgical treatment of solid tumors can contribute to increase the survival rate of affected children and to decrease the treatment-related morbidity. Considering these aspects, the successful implementation of innovations is described based on four examples...

Extrarenal nephroblastoma is an extremely rare tumor thought to be related to teratoid tumors of germ cell origin. Because few cases have been reported, no standard method for categorizing and managing these tumors exists. To our knowledge, there have only been 3 adult cases of nephroblastoma arising in a germ cell tumor of testicular origin in a nonatrophic testis, all in men aged 19 to 22 years and with aggressive clinical courses. We report a case of nephroblastoma in a nonatrophic testis, with nephroblastoma being the only non-germ cell component, in an older patient and with a more indolent clinical course that was responsive to localized treatment...

Mini-invasive surgery is more and more integrated in pediatric surgery. The robotic-assisted surgery brought new advantages from which the patient and the surgeon could benefit compared to laparoscopy. Its use in oncological surgery is still controversial. 12 robotic-assisted tumor resections with the da Vinci Surgical Robot (Intuitive Surgical, Sunnyvale, CA) were attempted in 11 children (mean age 7.65 years; age range 0.75-16.75 years; mean weight 30.3 kg; weight range 8.6-62 kg) in two centers. Mean total operative time was 145 min (range 72-263 min)...

Normal extracellular secretion of nephroblastoma overexpressed (NOV, also known as CCN3) is important for the adhesion, migration, and differentiation of cells. In previous studies, we have shown that the intracellular accumulation of CCN3 inhibits the growth of prominent neurons. Increased intracellular CCN3 can be induced through various processes, such as transcription, detoxification, and posttranslational modification. In general, posttranslational modifications are very important for protein secretion...
