Sinus pericranii: a scalp mass in a 6-month-old boy

'Sinus pericranii' is an abnormal communication between the extracranial veins and the dural venous sinuses (usually the superior sagittal and the transverse sinuses). It is a rare childhood abnormality. We report a case of a 6-month-old boy presenting with a scalp swelling in the left parietal region. Ultrasound with color Doppler and MRI showed a dilated epicranial vein that communicated with the superior sagittal sinus. This anomalous venous connection is known as sinus pericranii. We describe the imaging findings, associated abnormalities and management of this rare vascular abnormality

Lung volume assessments in normal and surfactant depleted lungs: agreement between bedside techniques and CT imaging

Bedside assessment of lung volume in clinical practice is crucial to adapt ventilation strategy. We compared bedside measures of lung volume by helium multiple-breath washout technique (EELVMBW,He) and effective lung volume based on capnodynamics (ELV) to those assessed from spiral chest CT scans (EELVCT) under different PEEP levels in control and surfactant-depleted lungs

The Seatbelt Syndrome-Do We Have a Chance?: A Report of 3 Cases With Review of Literature

The seatbelt syndrome represents an injury pattern seen after motor vehicle accidents. It is secondary to either the misplacement of seatbelts over the abdomen or the misuse of the restraint systems. This syndrome is infrequent in the pediatric population and occurs mostly in school-aged children because recommended lap-shoulder belts and booster seats are often not used in this age group, so that the seatbelt lies over the abdomen. Sudden deceleration bends the child around the lap belt causing injuries to the viscera, head, and spine (Chance fracture), often associated with paraplegia. Because not all patients have an abdominal seatbelt sign, this syndrome can easily not be recognized with potentially life-threatening consequences. We report on 3 patients with the seatbelt syndrome and review the literature regarding prevalence, diagnosis, treatment, and prognosis of the different injuries and discuss the diagnostic challenges of intestinal lesions and their management. Following this accident pattern, in hemodynamically stable patients with a normal abdominal computed tomography scan, close surveillance is warranted to rule out intestinal lesions manifesting with progressive peritoneal irritation. In hemodynamically unstable patients, or if there is evidence of free air on the computed tomography scan, emergency abdominal exploration is required

Spontaneous tibiotalar arthrodesis as a complication of acute tibial osteomyelitis due to Panton-Valentine leukocidin-producing <it>Staphylococcus aureus</it>: a case report

Abstract Introduction Strains of Panton-Valentine leukocidin-producing Staphylococcus aureus producing a new pattern of disease have emerged worldwide. Infection with these bacteria typically presents as a life-threatening infection of soft tissues and bones, and may cause potentially devastating consequences. Case presentation We report a case of osteoarticular infection caused by Panton-Valentine leukocidin-producing Staphylococcus aureus. A 12-year-old Caucasian girl presented with acute osteomyelitis of the tibia associated with toxic shock syndrome, which was complicated by an unexpected spontaneous ankle arthrodesis. Conclusions Osteoarticular infections due to Panton-Valentine leukocidin-producing Staphylococcus aureus appear to be severe, and are characterized by their tendency to evolve towards serious complications. This case highlights the need for early and aggressive surgical procedures in conjunction with appropriate antimicrobial therapy and regular long-term follow-up.</p
