Early Renal Ultrasound in Patients with Congenital Solitary Kidney Can Guide Follow-Up Strategy Reducing Costs While Keeping Long-Term Prognostic Information.

We aimed to evaluate the prognostic value of renal length (RL) > 2 standard deviation scores (SDS) measured by renal ultrasound (RUS), across infancy, childhood and adolescence, in identifying which patients with congenital solitary functioning kidney (CSFK) are at lower risk of developing kidney injury (KI). We also estimated the cost saving of integrating the current follow-up protocols with an early RUS algorithm (ERUSA). Fifty-six CSFK adult patients who were 1-3 months old at first observation of undergoing RUS were enrolled.

Evolution of congenital anomalies of urinary tract in children with and without solitary kidney.

Background: We hypothesized that children with congenital solitary functioning kidney (CSFK) present forms of congenital urinary tract anomalies (CUTA) with higher chance of spontaneous resolution compared with patients with two kidneys.

Methods: We retrospectively selected 75 consecutive children with CUTA of the CSFK and 75 matched patients with unilateral CUTA but without CSFK (controls) with prenatal suspicion of unilateral CUTA and early evaluation. We compared the spontaneous CUTA resolution and the prevalence of kidney injury between groups at last follow-up.

Early Renal Ultrasound in Congenital Solitary Kidney May Help to Select Patients at Lower Risk of Associated Vesicoureteral Reflux.

Background: Vesicoureteral reflux (VUR) may be associated with renal dysplasia and reduced renal length (RL). The diagnosis of VUR in children with congenital solitary functioning kidney (CSFK) identifies patients at risk of kidney injury but exposes to invasive procedures.

Objective: We aimed to test the hypothesis that an RL >2 standard deviation score (SDS) in the first months of life - reflecting renal hyperplasia - could identify CSFK patients with lower probability of presenting VUR.

Congenital Solitary Kidney from Birth to Adulthood.

Purpose: To evaluate the course of prenatally diagnosed and early-enrolled congenital solitary functioning kidney patients followed until adulthood and to identify risk factors for kidney injury.

Materials And Methods: Among all congenital solitary functioning kidney patients followed (1993-2018), we recalled 56 patients with prenatal diagnosis and congenital solitary functioning kidney confirmation at 1-3 months of life reaching at least 18 years of age. Serum uric acid, heavy smoking (≥25 cigarettes/day) and overweight/obesity were clustered as modifiable risk factors.

In children with urinary tract infection reduced kidney length and vesicoureteric reflux predict abnormal DMSA scan.

Background: To evaluate sensitivity, specificity, and positive and negative predictive values (PPV and NPV, respectively) of renal ultrasonography (US) in predicting renal uptake defects or reduced renal function at Tc-99m dimercaptosuccinic acid (DMSA) scan (primary outcome). We also evaluated which factors could be associated with Tc-99m DMSA renal scan anomalies.

Methods: We retrospectively included all the patients with vesico-ureteral reflux (VUR) undergoing the first Tc-99m DMSA renal scan within 3 months from the most recent renal US between 2016 and 2018.

Antibiotics for urethral catheterization in children undergoing cystography: retrospective evaluation of a single-center cohort of pediatric non-toilet-trained patients.

Antibiotics are often used to prevent post-catheterization urinary tract infections (UTIs) in patients undergoing cystography. However, there is no universally accepted protocol and the literature data are conflicting. We aimed to determine prevalence and risk factors of post-cystography UTIs in non-toilet-trained children.

Congenital solitary kidney size at birth could predict reduced eGFR levels later in life.

Objectives: To evaluate the impact of congenital solitary functioning kidney (CSFK) length, measured early in life, on the eGFR levels during the follow-up.

Study Design: We retrospectively selected 162 CSFK patients undergoing, within 60 days of life, renal length (RL) measurement by ultrasound. We divided the population in: Group 1 = RL ≥ 2 standard deviation score (SDS).

Outcomes of a Cohort of Prenatally Diagnosed and Early Enrolled Patients with Congenital Solitary Functioning Kidney.

Purpose: We evaluated the clinical course of patients prenatally diagnosed and enrolled early with congenital solitary functioning kidney, and identified the risk factors for renal injury.

Materials And Methods: We retrospectively evaluated 322 patients with congenital solitary functioning kidney according to the inclusion criteria of 1) prenatal diagnosis of solitary kidney; 2) first evaluation at 1 to 3 months of life with confirmation of congenital solitary functioning kidney, and evaluation of possible associated congenital anomalies of the kidney and urinary tract by abdominal ultrasound, renal scintigraphy and cystography; and 3) absence of any condition potentially affecting renal function in the neonatal period as well as absence of renal injury at enrollment (1 to 3 months of life) confirmed by a normal estimated glomerular filtration rate, lack of proteinuria and hypertension. Followup of 306 patients was evaluated.

Small bowel metastasis from pancreatic cancer in a long-term survival patient with synchronous advanced malignant pleural mesothelioma: A case report and literature review.

Diffuse malignant pleural mesothelioma (MPM) is an aggressive tumor that originates from the surface of the pleura. Approximately 70% of cases are associated with chronic asbestos exposure. MPM is regarded as an incurable disease, with a median survival of ~2 years following intensive multimodality treatment.

Effects of α-lipoic acid therapy on sympathetic heart innervation in patients with previous experience of transient takotsubo cardiomyopathy.

Background: Takotsubo syndrome is a stress cardiomyopathy, characterized by reversible left ventricle (LV) apical ballooning in the absence of significant angiographic coronary artery stenosis. The frequent association with emotional stress suggests in this disease an autonomic nervous system involvement. We could think that a therapeutic treatment targeting heart sympathetic dysfunction could be of crucial importance.

Peri-procedural tight glycemic control during early percutaneous coronary intervention up-regulates endothelial progenitor cell level and differentiation during acute ST-elevation myocardial infarction: effects on myocardial salvage.

Background: We examined the effects of peri-procedural intensive glycemic control during early percutaneous coronary intervention (PCI) on the number and differentiation of endothelial progenitor cells (EPCs) and myocardial salvage (MS) in hyperglycemic patients with first ST-elevation myocardial infarction (STEMI).

Methods And Results: We conducted a randomized, prospective, open label study on 194 patients with STEMI undergoing PCI: 88 normoglycemic patients (glucose < 140 mg/dl) served as the control group. Hyperglycemic patients (glucose ≥140 mg/dl) were randomized to intensive glycemic control (IGC) for almost 24 h after PCI (n = 54; 80-140 mg/dl) or conventional glycemic control (CGC, n = 52; 180-200 mg/dl).

Inflammatory bowel disease: value in diagnosis and management of MDCT-enteroclysis and 99mTc-HMPAO labeled leukocyte scintigraphy.

Objectives: The aims of this study are: (a) to evaluate the reliability of Multidetector Computed Tomography Enteroclysis (MDCT-E) and (99m)Tc-HMPAO labeled leukocyte scintigraphy (TLLS), in inflammatory bowel disease, (b) to test the accuracy of the two techniques with regard to their histological results, (c) to define how each technique can influence the natural course of inflammatory bowel disease (IBD), (d) to assess the potential value of the two techniques combined.

Materials And Methods: Thirty-seven patients with suspected IBD underwent MDCT-E and TLLS. We made a separate assessment of the results shown by the two methods and then compared and contrasted the histological results of the two.

F-18-2-fluoro-2-deoxyglucose positron emission tomography compared to technetium-99m hexakis-2-methoxyisobutyl isonitrile single photon emission chest tomography in the diagnosis of indeterminate lung lesions.

Background: (18)FDG-PET plays a significant role in diagnosing malignancy of lung lesions but remains an expensive test available at a limited number of sites in Italy.

Objective: We prospectively compare the diagnostic accuracy of (99m)Tc-MIBI- SPECT and (18)FDG-PET in patients with indeterminate lung lesions to demonstrate that (99m)Tc-MIBI-SPECT may be considered as a valid alternative when (18)FDG-PET is not available.

Methods: 52 patients with indeterminate lung lesion were examined by (18)FDG-PET and (99m)Tc-MIBI-SPECT before surgery.

The role of technetium-99m hexakis-2-methoxyisobutyl isonitrile in the detection of neoplastic lung lesions.

Objective: Our goal was to determine the role of technetium-99m hexakis-2-methoxyisobutyl isonitrile ((99m)Tc-MIBI) in the detection of neoplastic lung lesions.

Materials And Methods: We prospectively studied 79 consecutive patients with indeterminate lung lesion between January 2006 and September 2007. All patients were submitted to (99m)Tc-MIBI single-photon emission chest tomography (SPECT) before invasive diagnostic procedure.

ROBO2 gene variants are associated with familial vesicoureteral reflux.

The SLIT2 receptor ROBO2 plays a key role in the formation of the ureteric bud, and its inactivation in mice leads to supernumerary ureteric bud development, lack of ureter remodeling, and improper insertion of the ureters into the bladder. Recently, two heterozygous ROBO2 missense mutations were identified in two families with primary vesicoureteral reflux occurring in combination with congenital anomalies of the kidney and urinary tract (VUR/CAKUT). This study investigated a possible causal role of ROBO2 gene variants in 95 unrelated patients with primary VUR (n = 78) or VUR/CAKUT.

A genome search for primary vesicoureteral reflux shows further evidence for genetic heterogeneity.

Vesicoureteral reflux (VUR) is the most common disease of the urinary tract in children. In order to identify gene(s) involved in this complex disorder, we performed a genome-wide search in a selected sample of 31 patients with primary VUR from eight families originating from southern Italy. Sixteen additional families with 41 patients were included in a second stage.

Long-term evolution of renal damage associated with unilateral vesicoureteral reflux.

Purpose: We determined the long-term evolution of renal damage associated with vesicoureteral reflux.

Materials And Methods: We retrospectively selected 74 consecutive children with unilateral primary vesicoureteral reflux, ipsilateral renal differential uptake less than 45% at dimercapto-succinic acid scintigraphy performed 4 to 6 months after urinary tract infection (60 patients) or shortly after diagnosis of vesicoureteral reflux investigated for prenatal hydronephrosis (14), and normal ultrasound and scintigraphic imaging of the contralateral nonrefluxing kidney. Average patient age at diagnosis was 3 years.

Parotid function after selective deep lobe parotidectomy.

Selective deep lobe parotidectomy is a demanding technique, but it preserves healthy glandular tissue, improves cosmetic results and minimises the incidence of Frey's syndrome. We have evaluated postoperative function of the superficial lobe of the parotid after selective resection of the deep lobe. Fourteen patients who each had a mass involving the deep lobe of the parotid were selected from 127 patients with tumours of the parotid gland who were seen and treated between January 2001 and March 2004.

Permanent renal parenchymal defects after febrile UTI are closely associated with vesicoureteric reflux.

The finding of scintigraphic renal defects in children with febrile urinary tract infection (UTI) even in the absence of vesicoureteric reflux (VUR) has led to the conclusion that VUR is a weak predictor of renal defects in these patients. We used isotopic cystography (IC) for diagnosis of VUR in children with febrile UTI. Dimercaptosuccinic acid renal scintigraphy was performed 6 months after cure of the last UTI.

Fever of unknown origin, infection of subcutaneous devices, brain abscesses and endocarditis.

The term 'fever of unknown origin' includes a wide range of conditions that often remain undiagnosed. The possibility of an infection must be promptly diagnosed in order to begin appropriate therapy. Imaging with radiopharmaceuticals, computed tomography, magnetic resonance imaging and ultrasound are the most commonly applied techniques, usually performed in addition to blood tests, biopsies or tissue cultures when required.

Continuous monitoring of left ventricle function by VEST in hemodialyzed patients.

Cardiovascular disease is a major cause of morbidity and mortality in chronic kidney disease. Radionuclide-based methods can be used for analyses on the perfusion of coronary arteries and ventricular function. The present study reports the use of a new procedure for continuous measurements of left ventricle function during a dialytic session with the use of a recently developed portable gamma radiation detector (ventricular function study system).

Blood pressure and cardiovascular involvement in children with neurofibromatosis type1.

We evaluated blood pressure in a sample of patients with neurofibromatosis type 1 (NF1), using ambulatory blood pressure monitoring (ABPM), to determine whether ABPM, when compared with casual BP recordings, allowed the detection of a higher risk for hypertension. We also evaluated the correlation between BP and vascular abnormalities. We studied 69 NF1 patients (36 males and 33 females) with a mean age of 11+/-4 years, divided into group A, with 24-h mean systolic blood pressure (SBP) or diastolic blood pressure (DBP) <95th percentile, and group B, with mean SBP or DBP >95th percentile.

A 69-year-old woman with persistent iron deficiency anemia.

In women, iron deficiency anemia-a result of chronic iron loss-is most common during the reproductive years because of physiologic demands such as menstrual blood losses and pregnancy. In other cases, iron deficiency anemia is generally attributed to occult gastrointestinal bleeding. Common causes of chronic gastrointestinal blood loss include erosive esophagitis, gastric and duodenal ulcers, vascular ectasias, colon adenomas, and cancers.
