Chondromesenchymal Hamartoma in Ectopic Thyroid Tissue in a Neonate.

A full-term male neonate presented with a left sided cervical lump at the level of the thyroid gland. Magnetic resonance imaging (MRI) showed a benign heterogeneous solid mass with lobulated margins. The tumor underwent complete excision.

Dynamics of nitroglycerin-induced exhaled nitric oxide after lung transplantation: evidence of pulmonary microvascular injury?

Background: In search of real-time molecular correlates to ischemia-reperfusion-induced lung injury, we explored the hypothesis that liberation of nitric oxide (NO) into exhaled breath after pulmonary microvascular bioconversion of nitroglycerin (GTN) is attenuated in clinical lung transplantation.

Methods: Exhaled NO was measured under basal conditions and after intravenous administration of GTN in patients undergoing lung transplantation. Patients undergoing routine cardiac surgery served as controls.

Correlation between pulmonary gas exchange and basal and nitroglycerin (GTN)-induced exhaled nitric oxide (eNO) in patients undergoing cardiac surgery.

The relationship between eNO and events in the alveolar-capillary unit in acute lung injury remains to be established. Since endogenous eNO largely originates from the airway epithelium, but nitroglycerin (GTN)-induced eNO is due to microvascular/alveolar metabolism, we have proposed to use basal and GTN-induced eNO as metabolic markers of the airway--and microvascular/alveolar function, respectively. The current work investigates the relationship between basal and GTN-induced eNO and oxygenation parameters (PaO(2)/FiO(2) ratio) in patients undergoing cardiac surgery utilising cardiopulmonary bypass (CPB).

A long-term follow-up of five patients with atresia of the common bile duct.

Background/purpose: Description of the long-term follow-up of 5 patients operated on for atresia of the common bile duct.

Methods: During a 25-year period (1960 to 1985) 45 infants underwent surgical exploration for biliary atresia (BA), of which, 5 (11.1%) were found to have atresia of the common bile duct.

Extremely long frenulum leading to a giant preputial sac associated with concealed penis.

We describe a case involving an abnormally long frenulum leading to a giant preputial sac on micturition associated with a concealed penis. The diagnosis, differential diagnosis and surgical correction are detailed.

[Changes of exhaled nitrogen-monoxide concentration in acute ischemia-reperfusion injury of the lung].

Introduction: Nitric oxide (NO) plays an important role in both the physiological control of the pulmonary vascular bed and in the pathophysiology of several lung diseases. Though our knowledge regarding NO has became wider several aspects are still a matter of debate. The technical developments allowing direct measurements of NO in the expired air have provided an opportunity to evaluate NO production and consumption in the clinical setting and exhaled NO has become a diagnostic and monitoring tool in acute and chronic lung diseases.
