Case Studies Case 1 During an annual physical examination, a 12-year-old girl complains of intermittent chest pain for the past 5 days that localizes to the left upper sternal border. The pain is sharp and stabbing, is 5/10 in intensity, increases with deep breathing, and lasts for less than 1 minute. The patient has no history of fever, cough, exercise intolerance, palpitations, dizziness, or ...

ment of the costochondral junctions and thickening of the wrists and ankles. X-ray shows cupping and widening of the distal ends of long bones. The serum alkaline phosphatase is raised and both calcium and phosphorus are diminished (Back & Cole, 1958; Palmer & Thomas, 1958). Cretinism in which there is stunted growth, delay in closure of the fontanelle, large tongue and umbilical hernia. The se...

Few previous studies have been made of the appearance of articular cartilage under the electron microscope. Cameron and Robinson (1958) examined the matrix of both articular and epiphysial cartilages in femora of infants who had died in the neonatal period. No observations were made upon the cells as they were unable to assess the extent of post mortem change. They described the presence in the...

OBJECTIVE Child dummies and injury criteria used in automotive crashworthiness environments are based on scaling from the adult and/or between children of different ages. Cartilage-to-bone ossification, spinal canal and joint developments of the spine, and strength attainments do not grow linearly from birth to maturity. Though this is known to medical professionals, age-based quantitative anal...

Brian B. Looney A US EPA directive and related technical protocol outline the information needed to determine if monitored natural attenuation (MNA) for chlorinated solvents is a suitable remedy for a site. For some sites, conditions such as complex hydrology or perturbation of the contaminant plume caused by an existing remediation technology (e.g., pump-and-treat) make evaluation of MNA using...

The importance of the principle of implantation of the internal mammary artery into the myocardium, as described by Vineberg (1946), is now well established. The advantages of implanting both internal mammary arteries into the myocardium have been described by Favaloro, Effler, Groves, Fergusson, and Lozada (1968), and this may be the operation of choice when this method is used. The median ste...

OBJECTIVE This study was conducted to discuss the treatment and management of a patient presenting with acute idiopathic costochondritis. CASE 64 year old male patient presenting with acute anterior chest pain of one week duration. TREATMENT High-velocity low-amplitude thrust manipulation was used to the zygapophyseal joints of the thoracic spine, costotransverse, and costochondral joints i...

Investigations carried out in 1931-32 revealed that the plasma phosphatase is increased in active rickets', the degree of increase corresponding to the severity of the disease. They also showed that, whereas the serum calcium and phosphorus rapidly returned to the normal amount under treatment, the decline in the figures for phosphatase was much more gradual, normal values not being regained un...

BACKGROUND In craniofacial microsomia (CFM) Type III patients, autogenous costochondral grafts (CCG) are conventionally used for the reconstruction of the ramus and condyle. The aim of this study was to describe the use of CCG in children with CFM in terms of outcomes, growth patterns, and complications. MATERIALS AND METHODS This is a retrospective study of nine, aged 4-12 years, patients wi...

Demineralized sections of normal bones of different species of mammals, including man, show a preferential uptake of Ca 45 at the level of the epiphyseal plate after in vitro incubation in a solution of C#5C12. Though demineralized sections of prebone and predentine also take up Ca 45 under similar circumstances, they do so to a considerably lesser extent (B61anger (I)). By this technique, age ...
