Use of Zoledronic Acid in a Neonate with Subcutaneous Fat Necrosis Complicated with Severe, Refractory Hypercalcemia.
2019
Objective Subcutaneous fat necrosis (SCFN) is a rare condition that may occur in the neonatal period. SCFN is an inflammatory disorder of the adipose tissue, usually found in full-term healthy infants who have a history of intrauterine or perinatal distress. It is usually a self-limited condition; however, in some cases, it can get complicated, leading to severe hypercalcemia that may be life-threatening. Study Design We report and describe a classic presentation of SCFN that led to severe hypercalcemia refractory to standard treatment. The diagnosis of SCFN was made based on the finding of subcutaneous nodules and of hypercalcemia. The serum calcium level reached 16.6 mg/dL. Hypercalcemia…
Renal artery denervation for treating resistant hypertension: Definition of the disease, patient selection and description of the procedure
2012
Arterial hypertension is responsible for a significant burden of cardiovascular morbidity and mortality, worldwide. Although several rational and integrated pharmacological strategies are available, the control of high blood pressure still remains largely unsatisfactory. Failure to achieve effective blood pressure control in treated hypertensive patients may have a substantial impact on individual global cardiovascular risk, since it significantly increases the risk of developing hypertension-related macrovascular and microvascular complications. Arterial hypertension is arbitrarily defined as 'resistant' or 'refractory' when the recommended blood pressure goals (clinic blood pressure below…
Bloodstream infections in intensive care unit patients: Distribution and antibiotic resistance of bacteria
2015
Vincenzo Russotto,1 Andrea Cortegiani,1 Giorgio Graziano,2 Laura Saporito,2 Santi Maurizio Raineri,1 Caterina Mammina,2 Antonino Giarratano1 1Department of Biopathology and Medical Biotechnologies (DIBIMED), Section of Anaesthesia, Analgesia, Intensive Care and Emergency, Paolo Giaccone University Hospital, University of Palermo, Palermo, Italy; 2Department of Sciences for Health Promotion and Mother-Child Care, University of Palermo, Palermo, Italy Abstract: Bloodstream infections (BSIs) are among the leading infections in critically ill patients. The case-fatality rate associated with BSIs in patients admitted to intensive care units (ICUs) reaches 35%–50%. The emergence and diffusi…

Effects of ectopic expression of NGAL on doxorubicin sensitivity.
2012
Neutrophil gelatinase-associated lipocalin (NGAL, a.k.a Lnc2) is a member of the lipocalin family which has diverse roles including stabilizing matrix metalloproteinase-9 from auto-degradation and as siderocalins which are important in the transport of iron. NGAL also has important biological functions involved in immunity and inflammation as well as responses to kidney damage. NGAL expression has also been associated with certain neoplasia and is important in the metastasis of breast cancer. Many advanced cancer patients have elevated levels of NGAL in their urine and it has been proposed that NGAL may be a prognostic indicator for certain cancers (e.g. breast, brain, and others). NGAL exp…
DESIGN OF SF3B1 SUBUNIT MODULATORS OF THE SF3B SPLICEOSOME COMPLEX
2022
The subject of this dissertation is the search for new therapeutic strategies for pancreatic cancer and aims to implement a Drug Discovery process for the rational design and synthesis of molecules active in the modulation of pathways related to the regulation of pre-mRNA splicing process. This research project is the result of a joint PhD between the University of Palermo, Italy, and the Department of Medical Oncology, VU University Medical Center, Amsterdam, The Netherlands. It integrates complementary skills in pharmaceutical chemistry and translational cancer research with a special focus on the rational design of new anticancer compounds potentially active on SF3B1 (Splicing Factor 3B …
Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy
2015
ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.
