Systemic Catheter-Related Venous Thromboembolism in Children: Data From the Italian Registry of Pediatric Thrombosis.

Background: Central venous catheters (CVCs) represent one of the main risk factors for venous thrombotic events (VTEs) in children.

Methods: We studied the Italian Registry of Pediatric Thrombosis (RITI) with regard to systemic radiologically confirmed CVC-related VTEs (CVC-VTEs) occurred during 6.5 years in children aged 29 days to 18 years.

Six minute walk test in Italian children with cystic fibrosis aged 6 and 11.

Six minute walk test (6MWT) is a field exercise test widely used in clinical practice, both in adults and in pediatric patients. The primary aim of the study is to evaluate the physical performance of the subjects and compare them with the predicted Italian values. The secondary aim is to verify the possible relationship between the 6MWT distance (6MWD) and the clinical variables of the sample.

Biomechanics considerations in the treatment of double traumatic non-contiguous subaxial cervical lesions.

Double traumatic non-contiguous lesions of the subaxial cervical region are a rare event mostly caused by multiple, simultaneous or rapidly consecutive high-energy-impact traumas. The modality of treatment chosen for these lesions must be related to local lower cervical spine biomechanics. We present the case of a 59 year-old patient who suffered a subaxial cervical spine double fracture-dislocation following a complex-dynamic trauma.

Collision tumor between a spinal schwannoma and chronic lymphocytic leukemia/small lymphocytic lymphoma: case report and review of the literature.

A collision tumor is one where two neoplasms of differing type occur at the same anatomical site. We present a patient suffering from non Hodgkin small cell lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) and complaining intense lumbar back pain refractory to medical treatment. Lumbosacral MRI showed an intradural extramedullary lesion in the left L2-L3 foramen with extracanalar development and compression of psoas muscle.

Lipoprotein(a) concentration, genetic variants, apo(a) isoform size, and cellular cholesterol efflux in patients with elevated Lp(a) and coronary heart disease submitted or not to lipoprotein apheresis: An Italian case-control multicenter study on Lp(a).

Background: Coronary artery disease (CAD) risk is greater with higher plasma lipoprotein(a)[Lp(a)] concentrations or smaller apoisoform size and putatively with increased cellular cholesterol loading capacity (CLC). The relationship between Lp(a) and CLC is not known. Information on Lp(a) polymorphisms in Italian patients is lacking.

The role of renal biopsy to improve small renal mass diagnosis and management: are there predictive factors for a higher detection rate?. The first Italian study of 100 cases.

Background: Incidence of small renal masses (SRMs) has increased over the last decade: in order to reduce overtreatment of benign lesions, renal tumor biopsy (RTB) has been advocated. The primary aim of this study were to establish the rate of diagnostic biopsies and the concordance rate between RTB and surgical pathology with regard to tumor histology. The secondary aim was to identify what predictive factors are associated with an initial diagnostic biopsy.

Proton magnetic resonance spectroscopy: ex vivo study to investigate its prognostic role in colorectal cancer.

Background: Proton Magnetic Resonance Spectroscopy (1H MRS) is used for clinical diagnosis in some tumours. The aim of this study is to explore ex vivo the potential of 1H MRS in identifying malignancy through metabolic markers in the perspective of its application in all cases of difficult diagnosis and after neoadjuvant treatment.

Methods: Spectroscopy was performed ex vivo on 29 colorectal specimens.

Aorto-duodenal fistula on an aortic endograft: a rare cause of late conversion after endovascular aneurysm repair.

The last few years have seen an increase in popularity of endovascular aneurysm repair because of the improvements made to the endografts design as well as experience gained by physicians, but the long-term results of this procedure are still uncertain. The majority of late complications after an endograft can be treated with an endovascular approach but, in some cases, it may need conversion to open surgery. In this paper, we discuss the case of a male patient who presented with an aorto-duodenal fistula on an endograft requiring explant.

Effects of selective H.E.L.P. LDL-apheresis on plasma inflammatory markers concentration in severe dyslipidemia: Implication for anti-inflammatory response.

Therapeutic plasmapheresis is a recognized medical procedure in which various techniques are used to separate and remove undesirable or excessively elevated plasma elements from blood. The main purpose of the procedure is to remove the substances responsible for the disease (autoantibodies, circulating immune complexes, lipoproteins and other molecules) from the patient's blood. Low-Density-Lipoproteins-apheresis (LDL_a) is the selective removal of all apolipoprotein-B100-containing lipoproteins: LDL, very low-density lipoprotein, and lipoprotein (a).

Minimally invasive treatment of portal hypertension, abdominal aortic aneurysm, and colon cancer: a case report.

Surgical therapy in cirrhotic patients has high morbidity and mortality. Hepatic function and complexity of surgical procedures strongly influence postoperative results. We report the case of a cirrhotic patient with portal hypertension, abdominal aortic aneurysm (AAA), and right colon cancer.

[Therapy of SSTI and role of tigecycline].

Therapeutic strategies in the management of skin and soft tissue infections should take account of different variables: epidemiological trends (community or hospital acquired infections), pathogen or pathogens involved, virulence, seriousness of pathology (possible co-morbidities, knowledge of local epidemiology and antimicrobial susceptibility patterns of community and hospital strains. Therapy often should be started promptly, and on an empiric base, once microbiological analysis have been performed, waiting for culture and antimicrobial susceptibility testing. Surgical incision and drainage represent essential therapeutic procedures in the treatment of many complicated skin and soft tissue infections such as abscesses and fasciitis.

Secondary tracheoesophageal puncture: blind technique with a rigid hysterometer.

Objectives/hypothesis: The use of a rigid esophagoscope during tracheoesophageal puncture for speaking valve insertion in laryngectomized patients may be hindered by stenosis of the esophagus, or arthritic deformation of the spine, limiting extension of the neck. To prevent complications we currently perform a blind technique in these patients with the use of a rigid hysterometer instead of the esophagoscope.

Methods: Ten patients underwent secondary tracheoesophageal puncture using a rigid hysterometer.

Abdominal aortic endograft infection: report of two cases and review of the literature.

Endovascular prosthesis infection after exclusion of an abdominal aortic aneurysm is a rare, dramatic event and its diagnosis and treatment are extremely complex. This particular complication has been less well explored in the literature than others such as endoleaks, migration or stent rupture. The incidence of aorto-iliac stent-graft infection is almost 0.

'Over-under' myringoplasty with umbus-anchored graft.

Introduction: 'Over-under' myringoplasty is a versatile and effective surgical technique for tympanic membrane repair. The main drawbacks are possible trauma to the inner ear, due to manipulation of the malleus, and graft detachment from the apical portion of the malleus during the healing process, with consequent reduction of sound transfer function. To obviate these disadvantages, we have modified the over-under myringoplasty by maintaining anchorage of the tympanic membrane to the umbus.

Surgical treatment of abdominal aortic aneurysm with concomitant renal cell carcinoma: a single-centre experience with review of the literature.

Aim: The association between abdominal aortic aneurysm (AAA) and renal cancer is becoming more frequent, raising several questions about therapeutic and surgical strategies of management for both diseases.

Methods: Between October 1988 and May 2004, 913 AAA patients underwent surgical or endovascular repair at the I Division of General Surgery of the University of Verona (Italy). In 61 cases (6.

Recreational substance use and tolerance of efavirenz in HIV-1 infected patients.

During the past few years, efavirenz has been increasingly used in the treatment of HIV1 infection. Its main side effect is a syndrome of central nervous system stimulation occurring in 40-50% of adults in the first few weeks of therapy which might be observed at increased frequency in subjects concurrently using recreational substances. We therefore conducted a single center, retrospective study in 134 patients treated with efavirenz and found no significant differences in CNS side effects or discontinuation rates between recreational substance (cocaine, ecstasy, cannabis) users and non-users.

Acute mediastinitis: a severe complication of transdermal therapy in a patient with ischaemic heart disease. A case report.

Acute mediastinitis is an uncommon and potentially devastating infection. Generally, mediastinitis occurs as a postoperative infection following median sternotomy. We describe a case of acute mediastinitis in a patient with ischaemic heart disease, secondary to the spread of cutaneous infection of the chest wall in the application site of transdermal nitroglycerine patches.

Left pneumonectomy for a second primary tumor after right upper lobectomy for superior sulcus tumor.

We report on a patient who underwent a left pneumonectomy for a second primary lung cancer after a right upper lobectomy and upper chest wall resection for a superior sulcus tumor. Although the postoperative course was complicated by sputum retention which required a temporary tracheostomy the outcome was good and the patient is now living without supplementary oxygen supply. Left pneumonectomy may be considered in patients with previous contralateral lobectomy when the preoperative evaluation of the patient shows an acceptable predicted postoperative pulmonary function.

Completion pneumonectomy: experience with 47 cases.

From 1982 through March 1994, fourty-seven patients underwent completion pneumonectomy for a reappearing lung cancer, lung metastases, late complications, benign lung diseases, and early complication of bronchial or pulmonary artery sleeve resections. Intraoperative bleeding was higher than in standard pneumonectomy; there was one intraoperative mortality (2.3%).

The coronary subclavian steal syndrome: an uncommon sequel to internal mammary-coronary artery bypass surgery.

Coronary subclavian steal syndrome is a possible sequel in patients who have undergone myocardial revascularization with an internal mammary artery. We report a case of this syndrome in a 67-years-old man. In 1990 he underwent a quadruple bypass: aorta-obtuse margin, aorta-right coronary (two sequential), internal artery mammary-descending coronary artery.

Chylothorax after pleuro-pulmonary surgery: a rare but unavoidable complication.

The incidence of chylothorax after pleuro-pulmonary operations as well as its treatment is reported. Of 1744 operations performed postoperative chylothorax developed in 13 (0.74%).
