Move • General: muscle tone, symmetric full joint range of movement, hyperlaxity/stiffness, contractures (are they xed or can they be overcome The frequency is highest in young children with half of all cases presenting in the rst 2yrs. Pathogenesis Septic arthritis can develop from osteomyelitis especially in neonates where infection spreads from the metaphysis via transepiphyseal vessels. It may also arise due to haematogenous spread of infection or by direct inoculation. Aetiology • Age <12mths old: Staphylococcus aureus, Group B streptococcus, Gram –ve bacilli, Candida albicans. Differential diagnosis this depends on age and joint involved: • Hip: transient synovitis, Perthes, slipped capital femoral epiphysis, psoas abscess, proximal femoral or vertebral osteomyelitis, discitis. In the older child—acute onset; decreased range of movements or pseudoparalysis; pain on passive motion; hot, warm, swollen joint; inability to weight bear; systemic symptoms of infection. Subluxation/dislocation, joint space narrowing and erosive changes are later signs. Long-term follow-up is needed as growth-related sequelae may not become apparent for months or years. Hip joint infection has the worst prognosis for anatomical and functional impairment. Complications Chondrolysis, ongoing infection and bone destruction, joint incongruity/ stiffness, and growth disturbance. The frequency of osteomyelitis is greatest in infants, with 33% of all cases in the rst 2yrs, and 50% occurring by 5yrs. Infection may also occur by direct inoculation (open fractures, penetrating wounds) or local extension from adjacent sites. In the infant, transphyseal vessels are patent and infection may spread to the adjacent joint causing a septic arthritis. Aetiology the yield for bacterial growth from synovial uid and bone aspirate is small; therefore organisms are not always isolated. Other organisms seen include the following: • Neonates: group B streptococcus and Gram –ve enteric bacilli. Symptoms and signs • Neonates characteristically do not appear ill and may not have fever. Examination • Inspection: asymmetry, scapular prominence, skin lesions (especially midline pits and haemangiomas), cafe au lait spots (associated with neurobromatosis), foot deformity, leg atrophy. Beware of the following, especially in young children—several weeks of symptoms; night pain; increasing symptoms; abnormal neurology; recent onset of scoliosis; night sweats. Investigate thoroughly, but remember 50% of children experience back pain by 15yrs of age. Discitis Inammation (probably infection) of the disc space: • Age group: any age (infants and children rather than adolescents). Congenital anomalies Diastematomyelia: spinal cord is split by a central cartilaginous/bony prominence. If bilateral and at the same level may result in anterior displacement of one vertebra upon another (spondylolisthesis). Rest and change of activities; consider short-term bracing, analgesia, hamstring stretches, and core strengthening. Sacral spine: sacral agenesis • Denition: hypoplastic/absent sacrum; most common in infants of diabetic mothers. Examination Assess: • Flexibility: stand, bend forwards, bend backwards (hyperextension). Scheuermann’s disease • Rigid, aching pain between shoulder blades; onset 10–15yrs (previously normal spine). Outcome Little evidence that patients with kyphosis <70° experience late progression, disabling pain, or neurological compromise. Risk factors Positive family history; daughters of affected mothers more likely to be affected, Marfans, neurobromatosis.

Interstitial Lung Diseases Associated with Collagen Vascular Diseases: Radiologic and Histopathologic Findings symptoms kennel cough generic ondansetron 8mg mastercard. Lymphangitic carcinomatosis appears as thickening of the interlobular septa and peribronchovascular bundle medicine hat college discount ondansetron 4mg on-line, often with a nodular appearance medications pictures ondansetron 4mg low price. Pulmonary veno occlusive disease demonstrates enlarged pulmonary arteries and thickening of interlobular septa. Pulmonary edema appears as thickening of the interlobular septa which are present in the provided image and thus is the correct answer. Solitary fibrous tumor Key: D References: Ana Gimenez, Tomas Franquet, Rosa Prats, Pilar Estrada, Jordi Villalba, Silvia Bague. Bronchogenic carcinoma appears as nodule/mass within the lung parenchyma and is often spiculated. Solitary fibrous tumor occurs in the pleural space and appears as a mass with smooth borders and incomplete sign which suggests that the finding is extraparenchymal in nature. Tuberous sclerosis can present as a cystic lung disease and typically involves the lung bases (not seen in this case). The cysts in this case have well-defined walls, unlike lucent lesions caused by destruction of the alveoli in emphysema. Hypersensitivity pneumonitis Key: C References: Semin Chong, Kyung Soo Lee, Myung Jin Chung, Joungho Han, O Jung Kwon, Tae Sung Kim. Pulmonary metastasis is commonly seen diffusely throughout the lungs, not confined to the upper lobes as was the case in this patient. They are found most commonly in the mediastinum, more so in the subcarinal location. Spectrum of Pulmonary Aspergillosis: Histologic, Clinical, and Radiologic Findings. Aspergillomas or Mycetomas or fungus balls is a saprophytic infection which occurs in individuals with a pre-existing cyst or cavity. Common causes of pre-existing cavity include Tuberculosis or Sarcoidosis within which mycetomas may occur. Which of the following structures is a core component of the secondary pulmonary lobule The bronchiole forms the center of the lobule with its accompanying pulmonary artery. The pulmonary vein is located at the peripheral portion of the secondary lobule within the interlobular septum. The interlobular septum is a band of fibrous tissue which surrounds the periphery of the secondary lobule. General Competency Radiology In-Training Test Questions for Diagnostic Radiology Residents May, 2018 Sponsored by: Commission on Publications and Lifelong Learning Committee on Residency Training in Diagnostic Radiology © 2018 by American College of Radiology. Diagnostic ultrasound state, “Physicians who supervise, perform and/or interpret diagnostic ultrasound examination should be licensed medical practitioners who have a thorough understanding of the indications for ultrasound examinations as well as a familiarity with the basic physical principles and limitations of the technology of ultrasound imagingPhysicians performing and/or interpreting diagnostic ultrasound examinations should meet at least one of the following criteria: Certifications in Radiology or Diagnostic Radiology by the American Board of Radiology, the Royal College of Physicians and Surgeons of Canada, or Le College des Medecins du Quebec, and involvement with the supervision and/or performance, interpretation, and reporting of 300 ultrasound examinations within the last 36 months. Per the above guidelines, physicians not board certified in radiology or not trained in a diagnostic radiology residency programs can perform/interpret diagnostic ultrasound if they complete the above mentioned criteria. In addition, physicians performing and/or interpreting diagnostic ultrasound examinations must be eligible for certification in Diagnostic Radiology by the American Board of Radiology and involvement with supervision and/or performance, interpretation and reporting of 300 not 500 ultrasound examinations within the last 36 months. It states Physicians must be board certified in Diagnostic Radiology by the American Board of Radiology or have involvement with the supervision and/or performance, interpretation and reporting of 700 ultrasound examinations within the last 36 months. However, the guidelines state that physician do not have to be board certified in radiology. The referring physician requests it but provides no specific history or other documentation Key: A References. Indications do not include referring physician request without specific history or documentation. Retropulsion of a fracture fragment causing severe spinal canal compromise is a relative contraindication for vertebroplasty. Epidurlal tumor extension with significant encroachment on the spinal canal is a relative contraindication. Autonomy, beneficence, nonmaleficence and justice are considered to be principles of which of the following parameters of medical practice The core principles of medical ethics are autonomy, nonmaleficence, beneficence and justice. The three fundamental principles of professionalism are: primary of patient welfare, patient autonomy and social justice.
