Toxicological and genotoxicological assessment of water extracts of sewage sludge and other biogenic wastes: A piece of the SLURP jigsaw puzzle.

Given the considerable quantities of biogenic matrices employed in agricultural applications, there is growing concern about the potential negative effects resulting from the presence of harmful contaminants. The project "SLURP - SLUdge Recovery in Agriculture: Environment and Health Protection" planned a multi-stage approach in which the application of a wide battery of bioassays was proposed as an effective tool to measure the direct interaction of matrices with the different components of the ecosystem, from the molecular to the whole organism level. The aim of the present study, which is a part of the "SLURP" project, was to characterise the toxicological and genotoxicological properties of water extracts from biogenic wastes using several assays based on plant, bacterial and human cells.

Plastics in biogenic matrices intended for reuse in agriculture and the potential contribution to soil accumulation.

The spread of biogenic matrices for agricultural purposes can lead to plastic input into soils, raising a question on possible consequences for the environment. Nonetheless, the current knowledge concerning the presence of plastics in biogenic matrices is very poor. Therefore, the objective of the present study was a quali-quantitative characterization of plastics in different matrices reused in agriculture as manures, digestate, compost and sewage sludges.

To spread or not to spread? Assessing the suitability of sewage sludge and other biogenic wastes for agriculture reuse.

Sewage sludge (biosolids) management represents a worldwide issue. Due to its valuable properties, approximately one half of the EU production is recovered in agriculture. Nevertheless, growing attention is given to potential negative effects deriving from the presence of harmful pollutants.

Qualitative and Quantitative Analysis of Latrine Management Approaches in Internally Displaced Persons Camps in Myanmar.

Water, sanitation, and hygiene (WASH) interventions provide dignity and prevent disease transmission. Sanitary facility provision (e.g.

Analysis of the variation of costs for sewage sludge transport, recovery and disposal in Northern Italy: a recent survey (2015-2021).

The cost for the recovery/disposal of residues produced by wastewater treatment plants (WWTPs) represents a relevant aspect in the economics of WWTP management. We elaborated and applied a desk-based methodology to analyze tender processes and to investigate quantitatively and qualitatively the variability of unit costs for sewage sludge (EWC 190805) management in Northern Italy from 2015 to 2021. We conducted a qualitative survey for operators of the sector.

Laboratory Efficacy of Locally Available Backwashing Methods at Removing Fouling in Hollow-Fiber Membrane Filters Used for Household Water Treatment.

Hollow-fiber membrane filters (HFMFs) for household water treatment (HWT) can efficaciously remove disease-causing organisms in laboratory settings. However, lower effectiveness in use in low- and middle-income countries (LMICs) and humanitarian contexts (HCs) has been observed and attributed to membrane fouling and the associated cleaning. In LMICs/HCs, it is not possible to prevent and control fouling using commonly known methods (e.

Lessons learned from conducting six multi-country mixed-methods effectiveness research studies on water, sanitation, and hygiene (WASH) interventions in humanitarian response.

Background: Provision of safe water, sanitation, and hygiene (WASH) to affected populations in humanitarian emergencies is necessary for dignity and communicable disease control. Additional evidence on WASH interventions is needed in humanitarian settings. Between 2008 and 2019, we completed six multi-country, mixed-methods effectiveness studies in humanitarian response on six different WASH interventions.

The "Lever Sign": a new clinical test for the diagnosis of anterior cruciate ligament rupture.

Purpose: A new clinical test for the diagnosis of ACL rupture is described: the so-called "Lever Sign". This prospective study on four groups of patients divided subjects on the basis of MRI findings (complete or partial ACL lesion) and the clinical phase of the injury (acute or chronic). The hypothesis was that this manual test would be diagnostic for both partial and complete tears of the ACL regardless of the elapsed time from injury.

Vaginal replacement in the pediatric age group: a 34-year experience of intestinal vaginoplasty in children and young girls.

Background/purpose: The absence of vagina is rare in the pediatric population. It can occur as a result of congenital malformations such as an aplasia of mullerian ducts (46,XX Mayer-Rokitansky-Küster-Hauser syndrome) or a complete androgen insensitivity syndrome (46,XY testicular feminizing syndrome). Intersex patients, who underwent reassessment of a female sex, need a genital reconstruction toward a feminine phenotype.

Evolution of the surgical management of bowel atresia in newborn: laparoscopically assisted treatment.

Purpose: The jejunal-ileal atresias are the most common cause of intestinal occlusion in neonatal period and the duodenal atresia is the most common cause of high bowel obstruction in newborn. The treatment classically used is performed by a transverse sovraumbilical laparotomy. The first "minimal-invasive" approach was performed at the end of the years '70.

Activation of the heat shock response in plants by chlorophenols: transgenic Physcomitrella patens as a sensitive biosensor for organic pollutants.

The ability to detect early molecular responses to various chemicals is central to the understanding of biological impact of pollutants in a context of varying environmental cues. To monitor stress responses in a model plant, we used transgenic moss Physcomitrella patens expressing the beta-glucuronidase reporter (GUS) under the control of the stress-inducible promoter hsp17.3B.

One trocar assisted pyeloplasty (OTAP): initial experience and codification of a technique.

Background: The Anderson-Hynes pyeloplasty is still the gold standard for the surgical treatment of the ureteropelvic junction obstruction (UPJO) in children. To reduce the surgical invasivity, laparoscopic (RPSc) and retroperitoneoscopic (RPSc) pyeloplasty have been proposed but concerns have been expressed. In the RPSc approach, the small operative space and the technical difficulties have limited the application and diffusion of this techinique while in case of laparoscopy, a transperitoneal technique is used to treat a retroperitoneal disease.

Congenital symptomatic intrahepatic arteriovenous fistulas in newborns: management of 2 cases with prenatal diagnosis.

Background: Fetal and neonatal hepatic arteriovenous fistulas are rare and associated with a high mortality rate; they can be prenatally detected by ultrasonography. Management of these malformations can be a challenge for pediatric surgeons.

Methods: Two patients with a prenatal diagnosis of intrahepatic arteriovenous shunts were treated at our institution in the last 2 years.

The role of emergency thoracoscopy in the management of congenital cystic adenomatoid malformation of the lung associated with oesophageal atresia.

Congenital cystic adenomatoid malformation of the lung associated with oesophageal atresia is exceptional. The authors describe a case of a mixed type I - II congenital cystic adenomatoid malformation of the left lung associated with oesophageal atresia and tracheooesophageal fistula in a male infant. The interesting aspect of this case is not only the extremely rare association - only two reports in the literature - but the surgical choices.

[Thoracoscopic management of suspected thoraco-pulmonary malignant diseases in pediatric age].

Recent improvements and miniaturization of instruments have encouraged a wider use of thoracoscopy and laparoscopy as a modality for diagnostic and operative procedures in pediatric age. The utility of thoracoscopy in pediatric patients with suspected thoracopulmonary oncological diseases is shown by diagnostic accuracy and, if necessary, the possibility to perform at the meantime a mininvasive surgery. We report the experience of our Institution in 16 patients with suspected thoraco-pulmonary oncological diseases and treated for this reason with thoracoscopy.

Agenesis of the appendix vermiformis.

Agenesis of the appendix vermiformis represents a rare condition that accounts in approximately 1 in 100.000 laparotomies performed for suspected acute appendicitis. L.

Laparoscopic antireflux surgery in neurologically impaired children.

From May 1996 to April 2002, 48 laparoscopic fundoplications were performed after failure of medical treatment in 47 neurologically impaired infants and children affected by gastroesophageal reflux. Indications for surgery included vomiting, recurrent upper airway infections, failure of medical therapy, feeding difficulties with failure to gain weight, and instrumental (barium swallow and pHmetry) diagnosis of gastroesophageal reflux. A standard approach was adopted, with minimal access modifications according to the patients' characteristics.

Laparoscopic removal of müllerian duct remnants in boys.

Purpose: Müllerian duct remnants (MDRs) are present in a male pseudohermaphroditic form characterized by failure of the müllerian duct to regress due to insufficient production or peripheral action of müllerian inhibiting substance. The MDR can be asymptomatic but it often results in infections, stones and voiding troubles. Furthermore, it may develop into a neoplasm.

Retroperitoneoscopic adrenalectomy in a residual of neuroblastoma.

The authors report a case of retroperitoneoscopic adrenalectomy in a child with neuroblastoma previously treated by chemotherapy. Usually the presence of malignant tumours is a contraindication to retroperitoneoscopic surgery. A restaging of the tumor was done by retroperitoneoscopy.

[Malignant primary tumors of the liver in childhood].

Twenty-one children (16 males, 5 females) with malignant primary hepatic tumors were admitted to the Pediatric Clinic of the University of Bologna between June 1973 and July 2001. The diagnosis was hepatoblastoma (HBL) in 16 cases; hepatocellular carcinoma (HCA) in 3 cases; undifferentiated sarcoma in 1, malignant rhabdoid tumour of the liver in 1. Median age at diagnosis was 1.

Blue rubber bleb nevus syndrome and gastrointestinal haemorrhage: which treatment?

Purpose: To describe a paediatric case of "Blue Rubber Bleb Nevus Syndrome" (BRBNS) or Bean's syndrome, a rare systemic disorder characterised by cutaneous and gastrointestinal vascular malformations that often lead to overt life-threatening gastrointestinal bleeding or occult blood loss with severe anaemia and iron deficiency.

Case Report: A 6-year-old girl with multiple characteristic cutaneous vascular lesions was admitted for a massive rectal bleeding. A few months previously she was endoscopically treated for gastric angiomas which developed into melaena.

The role of endoscopic surgery in paediatric oncological diseases.

Recent improvements in video imaging and instrumentation have encouraged a wider use of endoscopic surgery as a modality for diagnostic and operative procedures. To asses the utility and diagnostic accuracy of endoscopic surgery in children with oncological diseases, we reviewed our experience about thirty-eight patients affected by oncological diseases, referred to our Department since 1995. We performed laparoscopy in 22 cases, thoracoscopy in 14, 1 combinated procedure (laparoscopy + thoracoscopy) and retroperitoneoscopy in 1 case.
