We reviewed written and audio records of paramedic-base hospital radio contact to determine whether care differed from that suggested in standard prehospital care protocols. Records of all 659 contacts for seizure, syncope, abdominal pain, or altered mental state during 1987 (28.4% of all contacts) were scored for the use of standard therapies (such as intravenous access, oxygen, naloxone hydrochloride) and unanticipated therapies (intubation, nitroglycerin). Cases that involved unanticipated treatments were reviewed to determine whether they could have been prospectively identified by simple clinical findings. Standard therapies were used in the majority of patients. Unanticipated therapies were administered to 13 patients, all of whom had abnormal vital signs, diaphoresis, respiratory distress, or a second prominent symptom. Data suggest that protocols could replace radio contact for most patients and that the few who might benefit from radio contact can be easily identified. A 90% reduction in radio contacts in Los Angeles county could save $3 million each year.

A 52 year old patient was admitted for retrosternal pain not responding to nitroglycerin. Two years before he had suffered myocardial infarction. He had known cholecystolithiasis. Reinfarction was excluded, but the patient developed right upper quadrant abdominal pain with rebound tenderness, fever and leukocytosis. Abdominal sonography supported the diagnosis of acute cholecystitis. Acute illness resolved rapidly without complications under treatment with antibiotics. The patient underwent cholecystectomy during the free interval four weeks after discharge from the hospital. Intraoperative diagnosis was empyema of the gallbladder with cholecystolithiasis.

The two main problems in defining and classifying the syndrome of benign paroxysmal vertigo (BPV) in childhood are the vestibular function pattern and the relationship between BPV and migraine. 13 children suffering from this syndrome were submitted to complete otoneurological examination, including caloric and rotational labyrinthine stimulation with ENG recording, and to headache provocation tests with nitroglycerin, histamine and fenfluramine. Vestibular responses were normal in all except 2 cases which presented signs of central vestibular impairment at the level of the vestibulocerebellar pathways. Headache provocation tests were positive in 9 out of 10 children, and in 4 cases they induced a typical vertiginous attack instead of headache. In addition, several children had a positive family history for migraine, headache was frequently associated with the crisis and other signs of a 'periodic syndrome' (motion sickness, cyclic vomiting, abdominal pain) were present, unrelated to vertiginous attacks. During the follow-up period, some children responded positively to migraine treatment. BPV, like paroxysmal torticollis in infancy and the signs of the periodic syndrome, can be considered a migraine equivalent or a migraine precursor and could be due to the same vascular and/or biochemical mechanisms responsible for the migraine. In children, for anatomical or developmental reasons, these mechanisms could selectively affect parts of the brain stem, including the vestibular nuclei and vestibulocerebellar pathways.

Sixteen children with benign paroxysmal vertigo (BPV) are presented. The great majority had a family history of migraine, neurological and autonomic signs associated with vertiginous attacks, and headache or other sign of the periodic syndrome (motion sickness, cyclic vomiting, abdominal pain) unrelated to the attacks. Vestibular examination, including bithermal caloric and rotational testing with ENG recording, showed normal or transiently decreased vestibular function. Headache provocation tests with nitroglycerin, histamine and fenfluramine were positive in 9 of the 13 patients examined, and in 4 cases induced a typical vertiginous attack instead of headache. BPV can be considered a migraine precursor or a migraine equivalent, attributable to the same vascular and/or biochemical disturbances responsible for migraine.

The syndrome of abdominal angina is described in three patients receiving long-term hemodialysis. This clinical entity has not yet been described in patients with chronic renal failure. The classic triad of abdominal pain, weight loss, and diarrhea produces fear of eating. Most laboratory and radiologic investigations are inconclusive. Remarkable relief of symptoms occurs with maintenance of the hematocrit level above 30%, reduction of pump speed during hemodialysis to approximately 200 ml/min, use of a smaller surface area dialyzer, and administration of sublingual nitroglycerin. This clinical syndrome is often misdiagnosed, resulting in several unnecessary investigations, as well as unnecessary surgical procedures. Cholecystectomy is the operation most commonly done. All three of our patients died within ten months of diagnosis.

The maintenance of angina control was assessed in this multicenter (three sites), randomized, double-blind, parallel-group study. Patients with stable angina pectoris receiving twice-daily sustained-release (SR) diltiazem were switched to equivalent doses of once-daily controlled-delivery (CD) diltiazem or to diltiazem SR. Patients who were switched from diltiazem SR to diltiazem CD (n = 28) experienced a 5% increase in time to termination (p = 0.0004) on the exercise tolerance test (ETT), as well as an 8% improvement in time to onset of angina (p < 0.0001) on the ETT. A similar trend was observed in patients randomized to diltiazem SR (n = 7), which suggested a training effect, and, therefore, equal efficacy between diltiazem SR and diltiazem CD. During exercise testing in the diltiazem SR baseline phase, 77% of the patients did not experience angina, whereas 60% of the patients did not experience ST-segment depression. Following transfer to diltiazem CD, 79 and 61% of patients, respectively, remained angina- and ST-segment depression free. No significant changes in the number of angina attacks, nitroglycerin use, or any hemodynamic-related parameters were observed following transfer to diltiazem CD. Eleven percent of the patients receiving diltiazem CD experienced treatment-related adverse events, which were limited to headache and abdominal pain; these adverse events did not lead to discontinuation of treatment. These findings suggest that patients whose angina is controlled with twice-daily diltiazem SR can be safely and effectively switched to an equivalent daily dose of the once-daily diltiazem CD.

The effects on the sphincter of Oddi of intravenous administration of dipyrone, 2.5 g; tramadol, 50 mg; indomethacin, 75 mg; N-butylscopolamine, 20 mg; and nitroglycerin, 1 mg, in comparison to physiological saline were assessed in a single-blind study in 36 patients hospitalized with upper abdominal pain. Basal sphincter pressure and sphincter motility were measured for a 5-min period after treatment by endoscopic manometry. Nitroglycerin and dipyrone both caused a significant fall in basal sphincter pressure, while N-butylscopolamine and nitroglycerin produced a significant decrease in contraction frequency. Therefore, dipyrone, in contrast to tramadol and indomethacin, exhibits spasmolytic activity in addition to analgesia in biliary pain.

Lysinuric protein intolerance (LPI) results in low serum L-arginine, hyperammonemia, mental retardation, thrombocytopenia, and an increased frequency of bowel movements. Our objective was to evaluate the effects of low serum L-arginine, the essential substrate for reactions catalyzed by nitric oxide synthetase (NOS), on the serum nitric oxide (NO) level and coagulation activity in a patient with LPI. A 37-year-old Japanese man who presented with abdominal pain and subnormal fasting levels of serum L-arginine and L-lysine was found to have LPI. The result of oral administration of diamino acids was an increased in urine and a decrease in serum, thus confirming the diagnosis. A decrease in the platelet count and an increase in the plasma levels of thrombin-antithrombin III complex (TAT) and fibrin degradation products (FDPs) indicated the presence of subclinical intravascular coagulation. Serum levels of NO derivatives and L-arginine were determined after intravenous administration of L-arginine. The effects of intravenous L-arginine or transdermal nitroglycerin on the plasma level of TAT were also investigated. Serum levels of NO derivatives were significantly reduced in the LPI patient versus the healthy control group (n = 5). Intravenous administration of L-arginine increased the serum level of NO derivatives and the platelet count and reduced plasma TAT and FDP levels. The plasma level of TAT was also reduced by transdermal nitroglycerin. A decrease in the serum level of L-arginine in patients with LPI appears to result in a decrease in NO production. The improvement in plasma TAT levels produced by administration of intravenous L-arginine or transdermal nitroglycerin suggests that intravascular coagulation is exacerbated by the decrease of NO production in patients with LPI.

A 56-year-old female, who had been suffering from heart failure and diabetes mellitus, underwent posterior instrumentation in the prone position and anterior interbody fusion in the right lateral decubitus position for pyogenic spondylitis between the fourth and fifth lumbar spine under general and epidural anesthesia. We induced hypotensive anesthesia by using continuous infusion of dopamine, prostaglandin E1 and nitroglycerin in order to prevent heart failure and reduce the blood loss. After the operation, the patient complained of upper abdominal pain, nausea and vomiting. We found high levels of serum amylase and other pancreatic enzymes. The massive gas of small intestine was pooled in abdominal X-P, and the pancreatic head was slightly swollen in abdominal CT and US. Therefore we came to the diagnosis of postoperative acute pancreatitis. We administered a single bolus intravenous infusion of ulinastatine and continuous venous infusion of gabexate mesilate. As the serum amylase level gradually decreased, the patient improved. We suspect that postoperative pancreatitis was due to invasive anesthetic and surgical stress on the patient who had had pancreatitis in the preoperative period.
