Background: Life expectancy of patients with glycogen storage disease (GSD) type I has improved considerably, opening new problems correlated with adult age. In females polycystic ovaries (PCOs) has been described as frequently associated with the disease, however successful pregnancies have been reported. Whether or not GSD I is associated with impaired reproductive function is still unclear. Patients and methods: Data about female patients with GSD Ia and Ib, who were 16 years or older, were obtained from clinical records and interviews. Results: A total of 32 women with GSD I (25 GSD Ia, 7 GSD Ib), median age 26 years (range 16-55), were included. 9/32 patients had delayed menarche, 17/32 had irregular cycles, 8/22 had documented polycystic ovaries. Five successful spontaneous pregnancies in four patients with GSD Ia and two in a woman with GSD Ib were reported. The latter had development and enlargement of hepatic adenomas during pregnancies. Conclusion: Despite the high prevalence of irregular menstruation cycles and polycystic ovaries, fertility seems not to be impaired in women with GSD I. During pregnancy monitoring for adenoma development is mandatory. © 2012 SSIEM and Springer. Source

Little is known about the effect on the human foetus of long-term and acute exposure to caffeine. We studied the organisation of foetal sleep-wake states in 13 healthy near-term foetuses over a wide range of maternal plasma caffeine concentrations (0-13 μg/mL) reflecting normal lifestyle conditions (day 0) and again following intake of two cups of regular coffee (∼300 mg of caffeine) intermitted by 50 h of abstinence (day 2; acute effects). On either day, 2 h simultaneous recordings were made of foetal heart rate, general-, eye-, and breathing-movements. The recordings were analysed for the presence of each of four foetal behavioural states: quiet- and active-sleep, quiet- and active-wakefulness. There was a linear relationship between maternal caffeine content and the incidence of foetal general movements during active sleep on day 0 (R = 0.74; P < 0.02). After coffee loading on day 2, foetuses of non- or low-caffeine consumers showed increases in active wakefulness (P < 0.001), general movements (P < 0.05) and heart rate variation (P < 0.01) but lower basal heart rate (P < 0.01) compared with their day 0 values. The changes in foetal heart rate (variation) and behaviour occurred between 90 and 180 min post-consumption. In contrast, foetuses of habitual caffeine consumers remained unaffected suggestive of foetal tolerance to caffeine. The results indicate differential performance between foetuses regularly exposed to caffeine and those caffeine-naive, both under normal maternal lifestyle conditions and in response to maternal coffee ingestion. © The Author(s), 2010.

Background: Thymic epithelial tumours (thymoma and carcinoma) are exceptionally rare in children. We describe a national multicentre series with a view to illustrating their clinical behaviour and the results of treatment. Methods. From January 2000 all patients under 18 years of age diagnosed with "rare paediatric tumours" were centrally registered by the Italian centres participating in the TREP project (Tumori Rari in Et Pediatrica [Rare Tumours in Paediatric Age]). The clinical data of children with a thymic epithelial tumour registered as at December 2009 were analyzed for the purposes of the present study. Results: Our series comprised 4 patients with thymoma and 5 with carcinoma (4 males, 5 females; median age 12.4 years). The tumour masses were mainly large, exceeding 5 cm in largest diameter. Based on the Masaoka staging system, 3 patients were stage I, 1 was stage III, 1 was stage IVa and 4 were stage IVb. All 3 patients with stage I thymoma underwent complete tumour resection at diagnosis and were alive 22, 35 and 93 months after surgery. One patient with a thymoma metastasizing to the kidneys died rapidly due to respiratory failure. Thymic carcinomas were much more aggressive, infiltrating nearby organs (in 4 cases) and regional nodes (in 5), and spreading to the bone (in 3) and liver (in 1). All patients received multidrug chemotherapy (platinum derivatives + etoposide or other drugs) with evidence of tumour reduction in 3 cases. Two patients underwent partial tumour resection (after chemo-radiotherapy in one case) and 4 patients were given radiotherapy (45-54 Gy). All patients died of their disease. Conclusions: Children with thymomas completely resected at diagnosis have an excellent prognosis while thymic carcinomas behave aggressively and carry a poor prognosis despite multimodal treatment. © 2011 Carretto et al; licensee BioMed Central Ltd.

The European multicenter study LNESG1 was designed to evaluate the safety and efficacy of surgical treatment alone in patients with localised neuroblastoma. In a retrospective, observational study we examined the impact of image-defined risk factors (IDRF) on operative complications and survival (EFS and OS). Procedure: 534 patients with localised, non-MYCN amplified neuroblastoma were recruited between 1995 and 1999. Group 1 consisted of 291 patients without IDRF (Stage L1 in the International Neuroblastoma Risk Group (INRG) staging system), all treated with primary surgery. Group 2: 118 patients with IDRF (INRG Stage L2), also treated with primary surgery. Group 3: 125 patients in whom primary surgery was not attempted, 106 receiving neo-adjuvant chemotherapy. Results: In L1 patients (Group 1) 5-year EFS was 92% and OS 98%. In L2 patients (Group 2 and 3) EFS was 79% and OS 89%. The differences in both EFS and OS were significant. EFS and OS in Group 2 (86% and 95%) were significantly better than 73% and 83% in Group 3. In INSS stage 1, 2 and 3, EFS were respectively 94%, 81% and 76%. Except between stage 2 and 3 the differences were significant. OS were respectively 99%, 93% and 83%, all significantly different. The 17% operative complication rate in L2 patients was significantly higher than 5% in L1 patients. Conclusions: In localised neuroblastoma, IDRF at diagnosis are associated with worse survival rates and higher rates of operative complications. The impact of IDRF should become an integrated part of therapy planning. © 2015 Wiley Periodicals, Inc. Source

Rhabdomyosarcoma (RMS) is the most common pediatric soft tissue sarcoma and is mostly represented by the embryonal (ERMS) and alveolar (ARMS) histotypes. Whereas ERMS shows variable genetic alterations including TP53, RB1, and RAS mutations, ARMS carries a gene fusion between PAX3 or PAX7 and FOXO1. Epithelioid RMS is a morphologic variant of RMS recently described in adults. Five cases of epithelioid RMS were identified after histologic review of 85 cases of ARMS enrolled in Italian therapeutic protocols. Immunostaining analyses (muscle-specific actin, desmin, myogenin, AP-2β, EMA, cytokeratins, INI-1) and reverse transcription polymerase chain reaction assays to detect MyoD1, myogenin, and PAX3/7-FOXO1 transcripts were performed. In 4 cases DNA sequencing of TP53 was performed; and RB1 allelic imbalance and homozygous deletion were analyzed by quantitative real-time polymerase chain reaction. Histologically, epithelioid RMS displayed sheets of large cells without rhabdomyoblastic differentiation or anaplasia in 3 and prominent rhabdoid cells in 2; necrosis was evident in 4, often with a geographic pattern. Immunostainings for INI, desmin, myogenin (scattered cells in 4, diffuse in 1) were positive in all; EMA and MNF116 were positive in 2; AP-2β was negative. PAX3/7-FOXO1 transcripts were absent. In all cases RB1 was wild type, and a TP53 mutation at R273H codon was found in 1. All patients are in complete remission, with a median follow-up of 6 years. Epithelioid RMS may occur in children and is probably related to ERMS, as suggested by lack of fusion transcripts, weak staining for myogenin, negative AP-2β, evidence of TP53 mutation (although only in 1 case), and a favorable clinical course.
