Unrecognized Microscopic Hyphema Masquerading as a Closed Head Injury
Pediatrics, 1998Co-Authors: D K Coats, Evelyn A. Paysse, J KongAbstract:Objective. To present a child with an unrecognized microscopic traumatic hyphema and acute glaucoma who was initially treated as a closed Head Injury patient. Design. Case report and discussion. Results. Symptoms attributable to unrecognized occult ocular Injury in a child with sickle cell trait resulted in evaluation and treatment of the child for a closed Head Injury. Evaluation included a computed tomography scan of the Head and lumbar puncture. An ophthalmologic consultation later revealed a microscopic hyphema and acute glaucoma as the etiology of the child's signs and symptoms. Conclusions. Children who present with neurologic symptoms and a history of ocular trauma should undergo an ophthalmologic examination as soon as possible. Hyphema, even if not readily visible on physical examination, can result in the development of acute glaucoma with signs and symptoms that resemble a closed Head Injury.

monitoring of Head Injury by myotatic reflex evaluation
Journal of Neurology Neurosurgery and Psychiatry, 2000Co-Authors: J A Cozens, S Mille, I R Chambers, A D MendelowAbstract:OBJECTIVES—(1) To establish the feasibility of myotatic reflex measurement in patients with Head Injury. (2) To test the hypothesis that cerebral dysfunction after Head Injury causes myotatic reflex abnormalities through disordered descending control. These objectives arise from a proposal to use reflex measurements in monitoring patients with Head Injury. METHODS—The phasic stretch reflex of biceps brachii was elicited by a servo-positioned tendon hammer. Antagonist inhibition was evoked by vibration to the triceps. Using surface EMG, the amplitude of the unconditioned biceps reflex and percentage antagonist inhibition were measured. After standardisation in 16 normal adult subjects, the technique was applied to 36 patients with Head Injury across the range of severity. Objective (1) was addressed by attempting a measurement on each patient without therapeutic paralysis; three patients were also measured under partial paralysis. Objective (2) was addressed by preceding each of the 36 unparalysed measurements with an assessment of cerebral function using the Glasgow coma scale (GCS); rank correlation was employed to test a null hypothesis that GCS and reflex indices are unrelated. RESULTS—In normal subjects, unconditioned reflex amplitude exhibited a positive skew requiring logarithmic transformation. Antagonist inhibition had a prolonged time course suggesting presynaptic mechanisms; subsequent measurements were standardised at 80 ms conditioning test interval (index termed "TI80"). Measurements were obtained on all patients, even under therapeutic paralysis (objective (1)). The unconditioned reflex was absent in most patients with GCS less than 5; otherwise it varied little across the patient group. TI80 fell progressively with lower GCS, although patients' individual GCS could not be inferred from single measurements. Both reflex indices correlated with GCS (p<0.01), thereby dismissing the null hypothesis (objective (2)). CONCLUSION—Cerebral dysfunction in Head Injury is reflected in myotatic reflex abnormalities which can be measured at the bedside. With greater reproducibility, reflex measurements may assist monitoring of patients with Head Injury.

Neurodiagnostic Testing in Patients with Closed Head Injury
Clinical Eeg and Neuroscience, 1991Co-Authors: Peter G. BernadAbstract:This brief review summarizes the current understanding of mild closed Head Injury with postconcussion syndrome. It is to be emphasized that objective evaluation be performed because it is critical to the assessment of the patient. Increased awareness of patients with symptoms in association with heightened sensitivity and caring will go a long way in helping the millions of patients yearly with mild to moderate Head Injury. Only with objective scientific data will the understanding of the causes of the varied symptomatology of the postconcussion syndrome be thoroughly understood.
