The Th1 versus Th2 cytokine profile in cerebrospinal fluid after severe traumatic brain injury in infants and children.
To further characterize the Th1 (proinflammatory) vs. the Th2 (antiinflammatory) cytokine profile after severe traumatic brain injury (TBI) by quantifying the ventricular cerebrospinal fluid concentrations of Th1 cytokines (interleukin [IL]-2 and IL-12) and Th2 cytokines (IL-6 and IL-12) in infants and children. DESIGN: Retrospective study. SETTING: University children's hospital. PATIENTS: Twenty-four children hospitalized with severe TBI (admission Glasgow Coma Scale score, <13) and 12 controls with negative diagnostic lumbar punctures. INTERVENTIONS: All TBI patients received standard neurointensive care, including the placement of an intraventricular catheter for continuous drainage of cerebrospinal fluid. MEASUREMENTS AND MAIN ⋯ This study confirms that IL-6 levels are increased in cerebrospinal fluid after TBI in infants and children. It is the first report of increased IL-12 levels in cerebrospinal fluid after TBI in infants and children. Further, it is the first to report on IL-2 and IL-4 levels in pediatric or adult TBI. These data suggest that selected members of both the Th1 and Th2 cytokine families are increased as part of the endogenous inflammatory response to TBI. Finally, in that both IL-6 and IL-12 (but neither IL-2 nor IL-4) can be produced by astrocytes and/or neurons, a parenchymal source for cytokines in the brain after TBI may be critical to their production in the acute phase after TBI.

Survival and renal function in pediatric patients following extracorporeal life support with hemofiltration.
To determine variables associated with survival in pediatric patients treated with hemofiltration while receiving extracorporeal life support and to determine the probability for recovery of renal function among survivors. DESIGN: Retrospective database analysis. SETTING: University of Michigan pediatric nephrology database. PATIENTS: All pediatric patients treated with continuous hemofiltration while on extracorporeal life support at the University of Michigan between January 1990 and May 1999. A pediatric patient was defined as any child between birth and 18 yrs of age, including children treated in both the pediatric intensive care unit and neonatal intensive care unit. Indications for extracorporeal life support included both cardiac and pulmonary failure. INTERVENTIONS: Data analysis of patients who were treated with hemofiltration while on extracorporeal life support. Hemofiltration includes both ultrafiltration and hemofiltration with countercurrent dialysis. MEASUREMENTS AND MAIN ⋯ In patients receiving hemofiltration while on extracorporeal life support, survival is comparable to that reported in other extracorporeal life support or hemofiltration populations. Decreased survival in these patients may be associated with the use of vasopressor infusions and the occurrence of complications. Recovery of renal function occurs in most survivors.

Acute upper gastrointestinal (UGI) hemorrhage is a common, often serious condition encountered in the emergency department (ED). Previous research has suggested that transfusion of blood products may interfere with the hypercoagulable state induced by significant blood loss. Our objective was to determine whether the frequency of rebleeding is higher in patients with UGI bleeding who have received early blood transfusion. ⋯ Our results support previous research suggesting that transfused UGI bleed patients have a higher rate of rebleeding. However, because of the retrospective design, causality cannot be inferred.

Problems of Parkinson`s Disease within the Arab world are discussed and a number of solutions are presented that will help in the management of Idiopathic Parkinson`s Disease. The problems discussed are problems related to the diagnosis whereby no individual clinical feature has sufficient sensitivity and specificity to serve as the sole basis for distinguishing Parkinson`s disease from other diseases with Parkinsonian features. Problems related to the Unified Parkinson`s Disease Rating Scale are also discussed and convey a multitude of problems culturally distinct to the Arab world. Problems related to the medical treatment, selection of patients for surgery, the surgery itself and the surgeon, programming and rehabilitation are discussed in detail.

When evaluating a patient with a complaint of double vision, it is important to distinguish monocular versus binocular diplopia, which are differentiated by asking the patient to cover each eye separately. In the setting of binocular double vision, one of the two images disappears when either eye is covered, because diplopia is the result of ocular misalignment. On the other hand, monocular double vision resolves when the affected eye is covered, but remains when the opposite eye is occluded. ⋯ The main treatment objective of binocular diplopia is to restore the largest area of single binocular vision. Ideally, patients would be able to achieve single vision in all fields of gaze, but this is not always possible. The majority of patients are treated with either prism lenses or eye muscle surgery.
