Abstract: This article reviews the literature relevant to the possible causes, prevention, and treatment of hemiplegic shoulder pain. Shoulder pain and stiffness impede the rehabilitation of patients with hemiplegia. The cause of this complication is unknown, but it may be related to the severity of neurological deficits, preexisting or posthemiplegic soft tissue injury, subluxation, brachial plexus injury, or shoulder-hand syndrome. Shoulder pain may be preventable if risk factors can be identified and appropriate prophylaxis applied. Resolution of the condition depends on diagnosis and effective treatment at the onset of the symptoms. More clinical research is needed to clarify the cause of hemiplegic shoulder pain and to document the efficacy of prophylactic and treatment methods.

Abstract: The ability of insulin to stimulate tissue glucose uptake and lower plasma FFA concentrations was quantified in 12 individuals with normal glucose tolerance and 12 patients with noninsulin-dependent diabetes mellitus (NIDDM), further subdivided into obese and nonobese subjects. Measurements were made during 5-h glucose clamp studies, carried out at plasma insulin concentrations of about 10 microU/ml (0-150 min) and about 60 microU/ml (150-300 min). Differences between the patient groups were compared by two-way analysis of variance. The ability of insulin to either suppress plasma FFA concentrations or stimulate glucose uptake was significantly reduced (P less than 0.001) in patients with NIDDM, and this was true of both the obese and nonobese groups. The defect in the ability of insulin to suppress plasma FFA concentrations in patients with NIDDM was more apparent at the lower insulin concentration, whereas resistance to insulin-stimulated glucose uptake in NIDDM was more dramatic at the high insulin concentration. Finally, a significant correlation (r = -0.67; P less than 0.001) between insulin-stimulated glucose uptake and plasma FFA concentration was found in the entire group. These data emphasize the fact that patients with NIDDM are resistant to multiple actions of insulin, and that the magnitudes of the defect in insulin suppression of plasma FFA levels and stimulation of tissue glucose uptake are roughly comparable.

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.
