David J Hunter

Bull NYU Hosp Jt Dis 2008 ;66(3):251-60

Division of Research, New England Baptist Hospital, Boston, Massachusetts 02120, USA.

Historically plain radiography has been the primary investigative tool by which structure in osteoarthritis is measured. Magnetic resonance imaging (MRI) is widely used in medical diagnosis for its various advantageous features, such as high-resolution capability, the ability to produce an arbitrary anatomic cross-sectional image, and wide range of available tissue contrast. Its ability to image features such as the subchondral bone, cartilage and soft tissue structures means that its application in knee osteoarthritis (OA) raises hope of improving our understanding of structural associations of pain and function in OA joints, previously based on conventional radiography.

Calcium Pyrophosphate Dihydrate (CPPD) crystals deposit in articular fibro- or hyaline cartilage (chondrocalcinosis), joint capsules, synovium, periarticular ligaments and tendons resulting in an age dependent prevalence. These calcifications may be asymptomatic or may manifest as acute pseudogout arthritis, pseudorheumatoid arthritis, bursitis, tenosynovitis, tendinitis, polymyalgic syndrome or chronic pyrophosphate arthropathy. The diagnosis is based on the presence of intracellular CPPD crystals in synovial fluid detected by polarizing microscopy, the characteristic radiological changes and the typical clinical presentations.

Pulmonary oxygen consumption: a hypothesis to explain the increase in oxygen consumption of low birth weight infants with lung disease.

Intensive Care Med 2001 Oct;27(10):1636-42

Division of Neonatology, Department of Obstetrics and Gynecology, Ludwig Maximilian University, Munich, Germany.

Objective: We determined pulmonary oxygen consumption (VO2lung) in low-birthweight infants with acute lung disease to help explain the greater whole-body oxygen consumption (VO2wb) in these infants with than in those without lung disease.

Methods And Materials: Eleven infants (birth weight 1,076+/-364 g; gestational age 28+/-3 weeks) undergoing mechanical ventilation for respiratory distress syndrome were studied in their first week of life. We measured VO2wb by indirect calorimetry and simultaneously determined systemic oxygen uptake (VO2Fick) as the product of cardiac output (echocardiography) and the arterial-mixed venous oxygen content difference (cooximetry) assuming that VO2wb-VO2Fick accounts for VO2lung.

It is characterized by acute, subacute, or chronic joint inflammation and deposition of CPPD crystals in hyaline cartilage, fibrocartilage, and other soft tissue structures. We have learned a great deal about imaging findings of CPPD crystal deposition disease. Read More

[Pathomorphological findings in preterm infants].

Authors:
G Amann

Radiologe 2000 Jan;40(1):8-17

Institut für Klinische Pathologie, Universität Wien.

Pathomorphology in the preterm infant represents an interaction of morphological organ immaturity and neonatal management with their respective sequelae. PATHOMORPHOLOGICAL EXAMPLES: include the modification in the morphology of hyaline membrane disease and bronchopulmonary dysplasia as a consequence of modern neonatal therapy. Hemorrhagic and ischemic/ hypoxic lesions of the central nervous system may occur in age- and agent-related distributional patterns, with subependymal hemorrhage and periventricular leukomalacia representing the most important examples.

Lung disease in premature neonates: impact of new treatments and technologies.

Semin Roentgenol 1998 Apr;33(2):101-16

Department of Radiologic Pathology, Armed Forces Institute of Pathology, Washington, DC, USA.

Advances in perinatal medicine and neonatology have dramatically changed clinical outcomes for premature neonates and have ushered in a new era of radiological complexity. "Portable" chest radiographs continue to be the mainstay in diagnostic imaging of fragile newborns, but radiologists may be confronted with new and unexpected radiological expressions of once-familiar disease processes. Familiarity with the radiological impact of emerging treatments in premature neonates is essential for accurate film interpretation. Read More

The hypothalamic-pituitary-adrenal axis in preterm infants weighing < or = 1250 g: association with perinatal data and chronic lung disease.

Acta Paediatr 1998 Mar;87(3):313-7

Children's Hospital, Neonatal Intensive Care, Aachen University of Technology, Germany.

The hypothalamic-pituitary-adrenal axis (HPA) was examined in 34 ventilated preterm infants weighing < or = 1250 g during the first week of life to evaluate the association between adrenal suppression and subsequent chronic lung disease. The second aim of the study was to detect perinatal and clinical differences between the infants with and without persistent suppression of the HPA after completion of dexamethasone treatment for chronic lung disease. To evaluate the HPA, the corticotropin-releasing hormone stimulation test was performed, and the cortisol and adrenocorticotropic hormone (ACTH) levels were measured by radioimmunoassay. Read More

Bilateral multicystic kidney dysplasia in a fetus with neonatal pulmonary hyaline membrane disease: a case report.

Changgeng Yi Xue Za Zhi 1997 Dec;20(4):335-9

Department of Obstetrics and Gynecology, Chang Gung Memorial Hospital, Kaohsiung, Taiwan, R.O.C.

Multicystic kidney disease is the most common cause of neonatal renal mass and either the most or second most common neonatal abdominal mass. This disease is a congenital dysplasia of the kidney characterized by large nonhomogeneous dilations of the collecting tubules. It may occur unilaterally or bilaterally, and the incidence is about 1 out of 5,000 to 10,000 births. Read More

Subependymal caudothalamic groove hyperechogenicity and neonatal chronic lung disease.

Acta Paediatr 1997 Dec;86(12):1370-3

Department of Paediatrics, University Hospital, Gent, Belgium.

Chronic lung disease is associated with several poorly defined risk factors for impaired cerebral development. Late neonatal onset of subependymal hyperechogenic areas in the caudothalamic groove has been reported in association with dexamethasone treatment and postnatal cytomegalovirus infection. We reviewed charts of 18 patients who developed subependymal hyperechogenicity beyond the first week of life, as well as charts of 79 patients belonging to a prospective surfactant study group.

[The neonatal respiratory insufficiency syndrome: the role of the chest radiogram].

Radiol Med 1997 Nov;94(5):463-7

Istituto di Radiodiagnostica, Università, Pisa.

Introduction: Chest radiography is considered the most reliable diagnostic tool to study the respiratory distress syndrome in newborns and one of the few diagnostic investigations which can be used considering the clinical situation of these patients and the need of a prompt diagnosis.

Materials And Methods: We examined 124 newborns (56 males and 68 females) submitted to chest radiography at least once. Two radiologists analyzed the images investigating: a) chest expansion, b) reticulonodular opacities, c) aerial bronchograms, d) parenchymal consolidation, e) atelectasis, f) pneumothorax. Read More

Effect of birth order on incidence of periventricular-intraventricular hemorrhage in very low birth weight twins.

South Med J 1996 Dec;89(12):1156-8

Department of Radiology, University of Mississippi Medical Center, Jackson 39216-4505, USA.

The purpose of the study was to determine whether the incidence of periventricular-intraventricular hemorrhage (PV-IVH) is significantly different between the firstborn and secondborn of very low birth weight twins. The firstborn and secondborn of 102 sets of twins were compared by incidence of PV-IVH, mode of delivery, birth weight, 5-minute Apgar score, pH, duration of oxygen therapy, duration of ventilator support, and occurrence of patent ductus arteriosus, air leak, bronchopulmonary dysplasia, or hyaline membrane disease. PV-IVH was graded by the Papile classification. Read More
