Example Input: Abstract: The mechanism of the increased renal clearance of amylase and the amylase to creatinine clearance ratio (CAM/CCR) in acute pancreatitis remains controversial with both renal tubular dysfunction and altered glomerular permeability being invoked as explanations. To differentiate between these mechanisms, we investigated the quantity and character of protein excretion in 10 patients with pancreatitis. For a short period of time, seven of 10 patients had mild proteinuria with a mean protein excretion rate of 230 +/- 154 mg/24 hr. Proteinuria decreased in 9/9 survivors to 17 +/- 18 mg/24 hr. Albumin excretion rate initially was minimally increased in 10/10 patients with a mean of 61 +/- 40 mg/24 hr, decreasing during recovery in 8/9 survivors to 10.9 +/- 10.4 mg/24 hr (P less than 0.01). Electrophoresis of urine obtained during the acute phase consistently showed a low molecular weight proteinuria pattern that cleared with recovery. Twenty-one of 22 urinary samples with an elevated CAM/CCR had a low molecular weight protein pattern. All the above findings can be explained by alterations in renal tubular reabsorption of proteins without changes in glomerular permeability. In 2/4 patients a low molecular weight protein was present in urine specimens from the acute phase that was not present in highly concentrated urine specimens from the recovery period. This raises the possibility that an abnormal low molecular weight protein enters the serum in acute pancreatitis, which, after glomerular filtration, produces the renal tubular malfunction found in acute pancreatitis.

Example Input: Abstract: This report describes the nuclear cardiology procedures available for use as diagnostic techniques in patients with definite or suspected cardiovascular disease. The usefulness of myocardial imaging, radionuclide angiocardiography and other radionuclide cardiovascular imaging techniques is classified within specific disease states. The clinical utility of each technique is graded from I to IV, depending on the clinical importance of the technique (I = most important; IV = not indicated). A grade of V is given for methods now considered to be in their research phase. The usefulness of these methods is discussed in patients with acute ischemic heart disease, chronic ischemic heart disease, valvular heart disease, pulmonary vascular disease and hypertensive heart disease. Selected references are provided.

Example Input: Abstract: A 33-month-old girl presented with acute subarachnoid hemorrhage from a ruptured multilobulated fusiform aneurysm of the midbasilar artery. This rare lesion was treated surgically by occluding the basilar artery. Intraoperative brain stem auditory evoked potential and somatosensory evoked potential monitoring results did not change with basilar artery occlusion, suggesting that the occlusion would be tolerated. However, the amplitudes of brain stem auditory evoked potential Waves III-V to right ear stimulation were transiently reduced during left pontine retraction during the aneurysm exposure. The patient made a complete clinical recovery.
