11/182. Chest compressions in an infant with osteogenesis imperfecta type II: No new rib fractures. The case report of a newborn female with osteogenesis imperfecta type II who underwent cardiopulmonary resuscitation (CPR) with manual chest compressions for several minutes is presented. Chest radiographs taken before and after the chest compressions were administered were reviewed by several radiologists from 3 different hospitals and demonstrated no new radiographically visible rib fractures. collagen analysis, the patient's clinical appearance, and clinical course, as well as a consultant's opinion aided in confirmation of the diagnosis of osteogenesis imperfecta type II. A review of 4 previous studies concerning rib fractures and CPR is included. This unique case supports previous articles that have concluded that rib fractures rarely, if ever, result from CPR in pediatrics, even in children with a lethal underlying bone disease, such as osteogenesis imperfecta type II. cardiopulmonary resuscitation, chest compressions, osteogenesis imperfecta, rib fractures, bone disease.

12/182. Spontaneous rib fracture during pregnancy. A case report and review of the literature. No studies have demonstrated a direct relationship between pregnancy and rib fracture. A case of spontaneous rib fracture in the third trimester presents the opportunity to examine factors unique to pregnancy that may predispose the patient to stress fractures of the lower ribs. A 28-year old woman in week 31 of her pregnancy presented with the chief complaint of acute onset of right upper quadrant pain. A chest radiograph demonstrated a minimally displaced fracture of the right 10th rib. During pregnancy, the enlarging uterus causes certain opposing muscular forces to act on the ribs, making them more susceptible to fracture after minimal trauma or after repeated stresses such as a chronic cough.

13/182. Lung isolation for the prevention of air embolism in penetrating lung trauma. A case report. PURPOSE: To illustrate a new airway and ventilatory management strategy for patients with unilateral penetrating lung injury. Emphasis is placed on avoiding positive pressure ventilation (PPV)-induced systemic air/gas embolism (SAE) through traumatic bronchiole-pulmonary venous fistulas. CLINICAL FEATURES: A 14-yr-old male, stabbed in the left chest, presented with hypovolemia, left hemopneumothorax, an equivocal acute abdomen, and no cardiac or neurological injury. In view of the risk of SAE, we did not ventilate the left lung until any fistulas, if present, had been excised. After pre-oxygenation, general anesthesia was induced and a left-sided double-lumen tube (DLT) was placed to allow right-lung ventilation. bronchoscopy was performed. The surgeons performed a thorascopic wedge resection of the lacerated lingula. Upon completion of the repair, two-lung ventilation was instituted while the ECG, pulse oximetry, PETCO2, and blood pressure were monitored. Peak inflation pressure was increased slowly and was well tolerated up to 50 cm H2O. The patient's intravascular status was maintained normal. CONCLUSION: patients with lung trauma are at risk of developing SAE when their lungs are ventilated with PPV. In a unilateral case, expectant non-ventilation of the injured lung until after repair is recommended. ( info) |
14/182. Fracture of the first rib as a consequence of pertussis infection. We report the first described case of a first rib fracture secondary to pertussis infection. An 11-year-old boy presented with sudden onset of severe right-sided pleuritic chest pain on a background of a 6 week history of a coughing illness and considerable weight loss. Pertussis was clinically suspected and proven on serology. A cause for the severe pain was initially difficult to confirm, causing some concern regarding possible underlying pathology, but was later demonstrated to be due to a first rib fracture. The anatomy of the first rib, and the biomechanical forces placed upon it that are exacerbated during a coughing illness are described. ( info) |
15/182. Glomangiopericytoma causing oncogenic osteomalacia. A case report with immunohistochemical analysis. A 47-year-old woman suffered from gait disturbance due to back pain and muscle weakness. Laboratory data showed serum hypophosphatemia, elevated alkaline phosphatase, and a normal level of ionized calcium. Radiological examinations revealed multiple pathologic fractures in the ribs and pubic rami. She had had no episode of familial or any other notable disorder, and so she was initially treated with medication for adult-onset osteomalacia. However, 19 years later (when she was 66 years old), she noticed a soft-tissue tumor in her buttock. The tumor was excised. The histological features were those of glomangiopericytoma characterized by both glomus tumor-like and hemangiopericytoma-like structures. After removal of the tumor, her symptoms disappeared immediately. Laboratory data normalized 8 months later. To our knowledge, this is the first report of oncogenic osteomalacia caused by glomangiopericytoma. ( info) |
16/182. Case report: catheter-related epidural abscess. INTRODUCTION: Catheter-related spinal epidural abscesses are rare but increasing in incidence. CLINICAL PICTURE: An elderly gentleman received 4 days of continuous epidural analgesia following multiple traumatic rib fractures. Five days subsequently, he developed an extensive epidural abscess accompanied by backache, lower limb weakness, fever, leukocytosis and Staphylococcal bacteraemia. TREATMENT: He received appropriate intravenous antibiotics and underwent an emergent decompressive laminectomy. OUTCOME: A good outcome was achieved because of prompt diagnosis, appropriate intravenous antibiotics and timely surgical intervention. CONCLUSIONS: It is important to be vigilant and continue to maintain good clinical practice and a high index of suspicion for this procedural-related complication. ( info) |
17/182. Thoracic paravertebral block for management of pain associated with multiple fractured ribs in patients with concomitant lumbar spinal trauma. BACKGROUND AND OBJECTIVES: The need for continual neurological assessment in patients with lumbar spinal injury poses a challenge for effective management of pain associated with multiple fractured ribs. Two cases are presented to illustrate the benefits of using thoracic paravertebral block to control the pain of multiple fractured ribs without compromising the ongoing neurological assessment. CASE REPORT: Thoracic paravertebral block was used in 2 patients with concomitant multiple fractured ribs and lumbar spinal injury. Case 2 also had a head injury and there was moderate coagulopathy. The thoracic paravertebral catheter was placed in the upper thoracic region and radiological imaging was used to delineate spread before the injection of relatively small volumes (10 to 15 mL) of local anesthetic. In case 1, the thoracic paravertebral block produced ipsilateral segmental thoracic anesthesia, providing excellent pain relief for the fractured ribs. It also spared the lumbar and sacral nerve roots, preserving neurological function in the lower extremities and bladder sensation. In case 2, effective analgesia without systemic sedation and opioids resulted in the patient regaining consciousness, which allowed continuous assessment of central and peripheral neurological function. CONCLUSION: Thoracic paravertebral block is an option for managing pain associated with multiple fractured ribs in the presence of concomitant lumbar spinal injury requiring continual neurological assessment.

18/182. Horizontal gradient in ventilation distribution due to a localized chest wall abnormality. Horizontal gradients in the distribution of ventilation and of regional vital capacities, as well as a reversed vertical, esophageal pressure gradient, were observed in a patient with a unilateral painful chest wall lesion. The distribution abnormalities disappeared after surgical treatment. These findings suggest that the interdependency between chest wall and lungs, and within the latter, between lobes, is an important factor determining the regional distribution of ventilation and the pleural pressure gradient in man.

19/182. An unusual case of sudden death in an alcohol addict. The sudden and unexpected death of a 40-year-old female alcohol addict is described. At the autopsy recent rib fractures were found. The extremity of one fractured rib had caused a massive haemorrhage by erosion of a coronary artery. ( info) |
20/182. mitral valve plasty for mitral regurgitation after blunt chest trauma. A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE. ( info) |
