99mTc-DTPA Diuretic Renography with 3 hours late output fraction in the evaluation of hydronephrosis in children.

Objective: Dynamic renal scintigraphy complemented by late gravity assisted postvoid images to 60 minutes is a frequently used diagnostic test in the evaluation of hydronephrosis. The objective of this study is to evaluate the effectiveness in acquiring images at 180 minutes to calculate the late output fraction (LOF) of 99mTc-DTPA in the diagnosis of ureteropelvic junction obstruction (UPJO).

Materials And Methods: A retrospective study of 177 patients (196 renal units) of suspected cases of clinical UPJO was conducted.

Leukocyte-technetium-99m uptake in Crohn's disease: does it show subclinical disease?

Aim: To evaluate inflammatory activity in patients with Crohn's disease (CD) using technetium-99m-hexamethylpropyleneamine oxime (99mTc-HMPAO) granulocyte scintigraphy.

Methods: Twenty patients (7 male and 13 female) with CD and five healthy volunteers were selected for 99mTc-HMPAO granulocyte scintigraphy. The Crohn's Disease Activity Index (CDAI), blood tests and C-reactive protein (CRP) of each patient were performed 7 d before the scintigraphic images.

[Evaluation of the influence of patient age and spacer device volume on aerosol lung deposition].

Objective: To evaluate the efficacy of three frequently used spacer devices to deliver aerosol to the lung, and to compare radioaerosol deposition with each device in different age groups.

Methods: Nine healthy, non-smoking volunteers were recruited: three adults and six children, including three toddlers and three school age children. Qualitative and semi-quantitative analysis of radioaerosol deposition in the lung were carried out.

Outcome of apparent ureteropelvic junction obstruction identified by investigation of fetal hydronephrosis.

Objectives: The purpose of the study was to evaluate the outcome of prenatally detected ureteropelvic junction obstruction (UPJO) managed with a more conservative protocol.

Methods: The records and imaging studies of 77 consecutive neonates with UPJO identified by fetal hydronephrosis were reviewed. A nonoperative approach was attempted in patients with mild/moderate pelvic dilatation, renal units with good function as ascertained by DMSA scan and a non-obstructed pattern on DTPA.

Premature acute myocardial infarction in a child with nephrotic syndrome.

We report a case of acute myocardial infarction in a nephrotic child. A 7-year-old boy with a 4-year history of steroid-unresponsive nephrotic syndrome due to mesangial proliferation disease presented with acute vomiting and chest pain. An electrocardiogram showed ST elevation and pathological Q waves in leads consistent with anterior and septal myocardial infarction.

Increased gastric emptying induced by Helicobacter heilmannii type 1 infection in rats.

The association between Helicobacter pylori infection and gastric motility abnormalities is still controversial, partly because of the lack of an appropriate animal model. H. heilmannii type 1 (Hh1), a spiral bacterium that infects the stomach of both man and pigs, easily colonises and induces an inflammatory response in the gastric mucosa of rodents.
