Lipid emulsions in parenteral nutrition can interfere with pulmonary functions in patients displaying anomalies of the ventilation-perfusion ratio. The underlying mechanisms are unknown, but involve modifications of the production of vasoconstrictor and vasodilator eicosanoids as an effect of lipid infusion. Preferential synthesis of one or other of the eicosanoid types depends on the rate of a...

A 14 years old boy who had a ventriculo-peritoneal shunt since the age of 5 months, was hospitalized due to headaches, nausea, vomiting and abdominal distension. In abdominal CT and sonographic evaluation, pancreatic pseudocyst or mesentric cyst were suspected. Evaluation of the shunt by radionuclide, however, was diagnostic and revealed a pseudocyst at the peritoneal end of the shunt. Th...

The aim of this study was to evaluate the immune responses to intranasal and intrapulmonary vaccinations with the attenuated Mycoplasma hyopneumoniae (Mhp) 168 strain in the local respiratory tract in pigs. Twenty-four pigs were randomly divided into 4 groups: an intranasal immunization group, an intrapulmonary immunization group, an intramuscular immunization group and a control group. The lev...

BACKGROUND Intrapulmonary lipoma is extemely rare in children. So far, all reported pulmonary lipomas were from adult patients. METHODS We present herein a case of intrapulmonary lipoma in a child and a review of the related literature. RESULTS A 13-month-old boy was hospitalized because of cough and fever. Chest CT showed patchy infiltration and round-shape, hypodense homogeneous lesions l...

TOPIC: Pulmonary Manifestations of Systemic Disease TYPE: Medical Student/Resident Case Reports INTRODUCTION: Platypnea-orthodeoxia is a syndrome characterized by dyspnea and hypoxemia worse in the upright position improved while supine. It has wide range differential diagnoses which could be cardiac, pulmonary, or abdominal origin. CASE PRESENTATION: A 56-year-old female with past medical hist...
