Example Input: Abstract: The purpose of this study was to define as a distinct clinical entity the syndrome of neurapraxia of the cervical spinal cord with transient quadriplegia. The sensory changes include burning pain, numbness, tingling, and loss of sensation, while the motor changes range from weakness to complete paralysis. The episodes are transient and complete recovery usually occurs in ten to fifteen minutes, although in some patients gradual resolution occurs over a period of thirty-six to forty-eight hours. Except for burning paresthesia, pain in the neck is not present at the time of injury and there is complete return of motor function and full, pain-free motion of the cervical spine. In our series, routine roentgenograms of the cervical spine were negative for fractures or dislocations in all patients. However, the roentgenographic findings did include developmental spinal stenosis in seventeen patients, congenital fusion in five patients, cervical instability in four patients, and intervertebral disc disease in six patients. Spinal stenosis was determined by two different roentgenographic methods. The first was the standard method, and the second was a ratio method devised by us. Both measurements were made at the level of the third through the sixth vertebral body on a routine lateral roentgenogram of the cervical spine that was available for twenty-four of the thirty-two patients and for a control group of forty-nine male subjects of similar age who did not have any neurological complaints. Using the ratio method, a measurement of less than 0.80 indicated significant spinal stenosis in the group of twenty-four patients for whom roentgenograms were available, as compared with a ratio of approximately 1.00 or more in the control group. There was statistically significant spinal stenosis (p less than 0.0001) in all of the patients as compared with the control subjects by both methods of determining spinal stenosis. A survey of 503 schools participating in National Collegiate Athletic Association (NCAA) football in the 1984 season found that 1.3 per 10,000 athletes had a history that was suggestive of neurapraxia of the cervical spinal cord. The phenomenon of neurapraxia of the cervical spinal cord occurs in individuals with developmental stenosis of the cervical spine, congenital fusion, cervical instability, or protrusion of an intervertebral disc in association with a decrease in the anteroposterior diameter of the spinal canal. We postulate that in athletes with diminution of the anteroposterior diameter of the spinal canal the spinal cord can, on forced hyperextension or hyperflexion, be compressed, causing transitory motor and sensory manifestations.(ABSTRACT TRUNCATED AT 400 WORDS)

Example Input: Abstract: This study was designed to investigate the effect of middle-wave ultraviolet (UVB) radiation on mast cell functions using mouse ear skin as an in vivo model. Groups of UVB-irradiated BALB/c mice were given an intradermal injection of the mast cell degranulator compound 48/80 into ears at various time intervals (30 min-7 days) after a single exposure to a bank of fluorescent sunlamp tubes (10-100 mJ/cm2). Both the compound-evoked ear swelling response (ESR) and mast cell degranulation were significantly suppressed by preexposure to UVB (25-100 mJ/cm2) after 0 (30 min) to 3 days postirradiation, with a subsequent recovery by day 7. No such effects were observed in mice irradiated with 10 mJ/cm2. The ESR induced by 5-hydroxytryptamine was not significantly affected by UVB radiation during the experimental period. While within this dose range UV radiation itself caused neither loss of mast cell counts nor a measurable degree of degranulation in ear skin, exposure to larger amounts of UV energy (200-500 mJ/cm2) produced tremendous ear swelling with histologic features of mast cell degranulation in an early phase of inflammation. The results suggest that UVB radiation exerts a dual effect on mast cells and that administration of smaller amounts of UVB may alter the mast cell/vasoactive amine system, suppressing ear swelling in response to the degranulator. Vascular reactivities to vasoactive amines were not affected by UVB irradiation.

Example Input: Abstract: This study compares the clinical results of two basic variations of the modified Fontan/Kreutzer operation, direct atriopulmonary connection without an interposed valve versus atrioventricular connection using the native pulmonary valve and the potential pumping capability of the subpulmonary ventricular chamber. From January 1979 through June 1985, 84 patients with tricuspid atresia and ventriculoarterial concordance underwent the modified Fontan/Kreutzer operation at the Mayo Clinic. Sixty patients had atriopulmonary connection and 24 patients had atrioventricular connections. Preoperative characteristics of the two patient groups were similar, but there was a greater frequency of Waterston shunts in the atriopulmonary group (38% versus 17%) and greater frequency of Glenn shunts in the atrioventricular group (46% versus 15%). Mean pulmonary arteriolar resistance was 1.9 +/- 0.7 units in the atriopulmonary group and 1.1 +/- 0.8 units in the atrioventricular group (p less than 0.01). Early postoperatively, mean right atrial pressure was slightly higher in the atriopulmonary group than in the atrioventricular group (18 +/- 3 versus 16 +/- 3 mm Hg, p less than 0.01), but this difference was not reflected in the early or late results. Operative mortality was 5% for patients with atriopulmonary connections and 4% for patients with atrioventricular connections. At 3.5 years postoperatively, the overall survival rate was 89% +/- 4% for patients with atriopulmonary connection and 88% +/- 7% for patients with atrioventricular connections. We conclude that there is no important difference in the clinical outcome of patients undergoing modified Fontan/Kreutzer repair for tricuspid atresia with atrioventricular concordance with either of the two operative methods. The choice of the connection should be dictated by the anatomy, such as presence of pulmonary valve or arterial stenoses, size of outlet chamber, and the presence of anomalous coronary arteries.
