Light Passing

Using transillumination and a sensitive cadmium sulfide light meter, 145 newborns were screened for the presence of intracranial hemorrhage. Intracranial hemorrhage (ICH) was suspected when the light meter could not detect any light passing through the anterior fontanel when the light beam was directed through the frontal eminence. ICH was confirmed by cranial computed tomography or postmortem examination in all 17 infants not transmitting light. Spectrophotometry was performed on samples of cerebrospinal fluid (CSF) to demonstrate the mechanism through which blood in the CSF blocks light transmission.

The a bility of computed tomography to detect minimal differential changes in the x-ray, tissue absorption coefficient has been u t iliz e d to diagnose c lo t associated radiodensity a ltera tions in a variety of clin ic alsettings. Freshly extravasated blood generally exhibits greater radiodensity than circulating blood and a progressive diminution in the clot radiodensity is observed over a period of approximately 4 weeks. This phenomenon has been successfully employed in the diagnosis of intracranial hemorrhage and th e ir sequale. As im ilar approach has been used to detect hemorrhagic and/or thrombotic incidents in the torso. The following categories have been examined.

Abstract OBJECTIVE This is a unique case report of a fractured atlantoaxial interspinous multistranded cable leading to intracranial hemorrhage and spinal cord injury. CLINICAL PRESENTATION A 61-year-old woman, with a history of rheumatoid arthritis and C1-C2 interspinous wiring with allograft for atlantoaxial instability, presented with neck pain and progressive decline in mental status. Prior to transfer to our institution from a referral hospital, imaging studies revealed progressive hydrocephalus with interval development of subarachnoid and fourth ventricular hemorrhage. Initial and repeat angiographic work-up was negative for vascular lesions. Magnetic resonance imaging revealed a subdural hematoma and signal changes at the cervicomedullary junction. Computed tomography of the cervical spine revealed a fractured interspinous cable, intradural penetration, and atlantoaxial instability. INTERVENTION After ventriculostomy, both the patient's mental status and quadriparesis improved to a C on the American Spinal Injury Association (ASIA) scale. During surgery, the fractured cable and subdural hematoma were removed revealing an area of spinal cord impalement. She underwent C1-C3 lateral mass fixation with iliac crest autograft for fusion and was discharged to rehabilitation after a ventriculoperitoneal shunt was placed. At her 6-month follow-up, she was independent and had improved to ASIA E. Computed tomography confirmed fusion. CONCLUSION Spinal instrumentation eventually fails from pseudarthrosis and can cause neurological injury. In patients with atlantoaxial instability, direct C1-C2 screw fixation with posterior interspinous wiring using autograft offers the best chance for fusion. Cervical spine pathology can cause intracranial hemorrhage, and unconventional causes of injury must be considered when routine workup is negative.

Risk Of Progression

Purpose Positron emission tomography (PET) after chemotherapy can guide consolidating radiotherapy in advanced-stage Hodgkin lymphoma (HL). This analysis aims to improve outcome prediction by integrating additional criteria derived by computed tomography (CT). Patients and Methods The analysis set consisted of 739 patients with residues ≥ 2.5 cm after chemotherapy from a total of 2,126 patients treated in the HD15 trial (HD15 for advanced stage Hodgkin's disease: Quality assurance protocol for reduction of toxicity and the prognostic relevance of fluorodeoxyglucose-positron-emission tomography [FDG-PET] in the first-line treatment of advanced-stage Hodgkin's disease) performed by the German Hodgkin Study Group. A central panel performed image analysis and interpretation of CT scans before and after chemotherapy as well as PET scans after chemotherapy. Prognosis was evaluated by using progression-free survival (PFS); groups were compared with the log-rank test. Potential prognostic factors were investigated by using receiver operating characteristic analysis and logistic regression. Results In all, 548 (74%) of 739 patients had PET-negative residues after chemotherapy; these patients did not receive additional radiotherapy and showed a 4-year PFS of 91.5%. The 191 PET-positive patients (26%) receiving additional radiotherapy had a 4-year PFS of 86.1% (P = .022). CT alone did not allow further separation of patients in partial remission by risk of recurrence (P = .9). In the subgroup of the 54 PET-positive patients with a relative reduction of less than 40%, the risk of progression or relapse within the first year was 23.1% compared with 5.3% for patients with a larger reduction (difference, 17.9%; 95% CI, 5.8% to 30%). Conclusion Patients with HL who have PET-positive residual disease after chemotherapy and poor tumor shrinkage are at high risk of progression or relapse.
