Abstract Introduction Carbon dioxide (CO2) used in laparoscopy evokes local and systemic effects. This study was designed to evaluate the histopathologic morphologic changes due to CO2 and air insufflation, at different pressure levels, on visceral and parietal peritoneum in rats. Materials and Methods A total of 56 rats were object of the study, randomly divided into five groups. Pneumoperitoneum (PN) was maintained for 30 minutes, at a flow rate of 0.5 L/min and at a pressure of 10 and 6 mm Hg with CO2 (group S1-S2, n = 32) and filtered air (group A1-A2, n = 16). Only anesthesia was performed in the fifth group (group C, n = 8). Peritoneal samples were obtained 24 hours later for blinded histological evaluation. A grading system was adopted to evaluate histological peritoneal changes (0, no change; 1, mild; 2, moderate; and 3, severe) such as mesothelial aspect, inflammatory response, edema, and hemorrhage. The score reflected the severity of damage and was calculated by the sum of the degree evaluated separately. Values were compared with the analysis of variance analysis. Results CO2 and air insufflation caused reactive mesothelial cells and peritoneal inflammation of different degrees depending on the level of intra-abdominal pressure (IAP) and type of gas. These modifications were absent in group C and were less evident in low pressure S2 group with respect to S1 and A1-A2 groups. The average values of histopathologic peritoneal score showed significant differences between S2 (11.5) versus S1 groups (16.83) with respect to A groups (A1 = 27.83; A2 = 20.5) and compared with the controls (C = 2.5). Conclusions Our data confirm that PN affects the peritoneal integrity. The grades of morphological peritoneal changes are related to the level of IAP. Low CO2 pressure causes minor peritoneal changes with respect to high pressure and air insufflation. © 2014 Georg Thieme Verlag KG.

Background and aims: Evaluation of incidence and correlates of severe hypoglycemia (SH) and diabetes ketoacidosis (DKA) in children and adolescents with T1DM. Methods and results: Retrospective study conducted in 29 diabetes centers from November 2011 to April 2012. The incidence of SH and DKA episodes and their correlates were assessed through a questionnaire administered to parents of patients aged 0-18 years. Incidence rates and incident rate ratios (IRRs) were estimated through multivariate Poisson regression analysis and multilevel analysis. Overall, 2025 patients were included (age 12.4±3.8 years; 53% males; diabetes duration 5.6±3.5 years; HbA1c 7.9±1.1%). The incidence of SH and DKA were of 7.7 and 2.4events/100py, respectively. The risk of SH was higher in females (IRR=1.44; 95%CI 1.04-1.99), in patients using rapid acting analogues as compared to regular insulin (IRR=1.48; 95%CI 0.97-2.26) and lower for patients using long acting analogues as compared to NPH insulin (IRR=0.40; 95%CI 0.19-0.85). No correlations were found between SH and HbA1c levels. The risk of DKA was higher in patients using rapid acting analogues (IRR=4.25; 95%CI 1.01-17.86) and increased with insulin units needed (IRR=7.66; 95%CI 2.83-20.74) and HbA1c levels (IRR=1.63; 95%CI 1.36-1.95). Mother's age was inversely associated with the risk of both SH (IRR=0.95; 95%CI 0.92-0.98) and DKA (IRR=0.94; 95%CI 0.88-0.99). When accounting for center effect, the risk of SH associated with the use of rapid acting insulin analogues was attenuated (IRR=1.48; 95%CI 0.97-2.26); 33% and 16% of the residual variance in SH and DKA risk was explained by center effect. Conclusion: The risk of SH and DKA is mainly associated with treatment modalities and strongly depends on the practice of specialist centers. © 2013 Elsevier B.V.

Introduction. Rare disease registries are a priority at European level and specific actions are being implemented by the European Commission to support their development. In Italy, a National Registry of rare diseases has been established in 2001 as a network of regional registries. The latter have gradually been established and the full coverage of the Italian territory was attained during 2011. Methods. Here we describe the basic features of the National Registry of rare diseases; the activities carried out to promote consistent operations in the regional registries; and the overall quality and composition of the records collected. Results. After a validation process, including removal of duplicate records, 110,841 records of patients with rare diseases, single and with group denominations, are stored in the National Registry of rare diseases. They correspond to the overall diagnoses communicated to national registry by regional registries up to 30 June 2012. The quality of the data collected by the the National Registry of rare diseases has been assessed with respect to completeness and consistency of procedures. Variables characterising case and diagnosis showed a very limited number of missing values. Records reported at least one case of 485 rare conditions. Discussion. To date, the National Registry of rare diseases is a surveillance system with the main objective of producing epidemiologic evidence on rare diseases in Italy, and of supporting policy making and health services planning. Data quality still represents a limitation for any sound epidemiological estimate of rare diseases in Italy. However, improvements of the quality of collected data and the completeness of case notifications should be strengthened. © SIMTI Servizi Srl.

Objective: The goal of this study was to define the long-term outcome of absence epilepsy presenting before the age of 3. years. Methods: We retrospectively studied the medical records of 40 children from eight neuropediatric centers in Italy with respect to the personal and family histories of epilepsy or febrile seizures, time of follow-up, cognitive functions, treatment, and outcome. Results: Forty patients were enrolled in this study. They all fulfilled the criteria for absence epilepsy with 3-Hz spike-wave complexes on the EEG, normal neurological examination, and no other seizures types. Seizure onset occurred between 24.1 and 36.0. months. There was a family history of epilepsy in 28%, and of febrile seizures in 13%. Thirty-three patients were treated with valproic acid (VPA), mostly used in monotherapy (26 patients) or in association with ethosuximide. At final follow-up, 33 patients were seizure free and 29 had normal EEGs. Thirty-four patients had a normal intelligence quotient (IQ), whereas 6 had a decreased IQ, mainly associated with poor control of seizures. Conclusion: In our series, absence seizures presenting before the age of 3 appeared to have quite a good long-term clinical prognosis; the neuropsychological outcome was comparable to that of childhood epilepsy presenting after 3. years of age. © 2010 Elsevier Inc.

Object: To retrospectively review the value of laparoscopy in the management of impalpable testis. Materials and methods: In 1993-2006, 182 laparoscopies for impalpable testis were performed for a total of 194 testicular units. Five laparoscopic findings were considered: testicular ectopia, intra-abdominal testis, and cord structures that are blind ending, completely absent (agenesis) or entering the internal inguinal ring. Results: In 62 cases an intra-abdominal testis was found; 18 were classified as high and managed by a laparoscopic Fowler-Stephens procedure. Cord structures entering the inguinal ring were observed in 77 patients and 45 underwent an inguinal exploration: a testis was found in 12 cases and in 33 a remnant was excised. In 35 cases, intra-abdominal blind ending vas and vessels were observed and eight showed testicular agenesis. No major surgical complications were recorded. Follow up ranged from 1 to 3 years. Conclusions: Our study confirms the value of laparoscopy in the management of non-palpable testis, providing a definitive diagnosis by the direct view of spermatic bundle and testis. Ninety-three patients were managed by laparoscopy only, and in 44 it was essential for the subsequent surgical approach. When the internal inguinal ring is patent and/or normal spermatic vessels are present an inguinal exploration is mandatory. © 2010 Journal of Pediatric Urology Company. Published by Elsevier Ltd.
