Successful percutaneous removal of broken umbilical vein catheter in a very low-birth-weight preterm infant.

A 28-week-old preterm infant with a birth weight of 1250 g had a broken segment of umbilical vein catheter (UVC) lodged in the right atrium. It was observed that a 7-cm fragment of catheter had migrated to the right atrium through the inferior vena cava. The catheter was successfully retrieved by fluoroscopically guided percutaneous cardiac catheterization, using a cobra catheter and snare wire, without complication. Fracture and embolization of UVC is a rare but serious complication. Presently described was a case of fractured and embolized UVC in a very low-birth-weight preterm infant, and its successful retrieval via percutaneous endovascular approach.

Pleomorphic adenoma of the palate.

Pleomorphic adenoma is the most common mixed benign tumor of major salivary glands. Approximately 80% of these tumors arise in the parotid gland, whereas 7% arise in the minor salivary glands. The most common sites for minor salivary gland where pleomorphic adenoma arises are the palates followed by lips and cheek. We report a palate mass in a 46-year-old male patient. The initial cytologic diagnosis by fine-needle aspiration biopsy was pleomorphic adenoma. This report describes a case of pleomorphic adenoma regarding all distinctive diagnoses with the review of the literature.

Efficacy of salbutamol and ipratropium bromide in the management of acute bronchiolitis--a clinical trial.

BACKGROUND: A wide range of drugs are commonly used to treat bronchiolitis, but evidence of their effectiveness is limited. OBJECTIVES: To investigate the efficacy of ipratropium bromide and salbutamol in the treatment of patients with moderate-severe bronchiolitis. METHODS: Sixty-nine infants with moderate-severe bronchiolitis hospitalized at their first episode of wheezing or crepitations in the chest were enrolled in a prospective, double-blind, placebo-controlled trial. Patients were randomly assigned to receive nebulized salbutamol, ipratropium bromide or placebo. Main outcome measures were changes in oxygen saturation rates and clinical scores and duration of hospitalization. RESULTS: In the bronchodilator groups, clinical scores were better compared to the placebo group at 30 min (8.4 +/- 1.3 vs. 7.5 +/- 0.8, p < 0.05). Bronchodilator groups had also significantly lower clinical scores (7.3 +/- 1.2 vs. 5.9 +/- 1.1, p < 0.0001, and 5.3 +/- 1.4 vs. 4.5 +/- 1.6, p = 0.006, respectively) and higher oxygen saturation rates compared to the placebo group at 8 and 24 h (89.6 +/- 2.4 vs. 94.3 +/- 4.4, and 92.2 +/- 2.6 vs. 95.9 +/-4.4, respectively, p < 0.0001). Improvement rates and duration of hospitalization were not statistically different among groups. CONCLUSIONS: Clinical scores and oxygen saturation levels improved more rapidly in the bronchodilator groups than in the placebo group up to 24 h, but these drugs did not have a sufficient effect to change the natural course of the disease.
