One hundred and three patients with moderate and severe cancer pain were given a sublingual analgesic agent--dihydroetorphine hydrochloride (DHE). Relief of cancer pain was moderate or complete in 89.3% (92/103). The average relief time (ART) was 3.9 hours and the average time before effectiveness was 20 minutes. In patients with acute or chronic cancer pain, moderate and complete pain-relief rates were 91.3% and 82.2% (P = 0.237). Difference of ART between them was insignificant (P = 0.299). The main clinical side-effects were somnolence (60%), dizziness (72%), nausea (30%), vomiting (16.5%), constipation (5%) and shortness of breath (8%). In two of the patients, the administration of DHE had to be stopped due to its side-effects. Age, sex and site of cancer pain were not related to the analgesic effects of DHE, but the pain-relief in patients with bladder cancer was poor (P less than 0.001). Within certain range, increase in dose was able to enhance its analgesic effect (P less than 0.001) and reduce drug resistance (P less than 0.001).

To determine the pattern of emergency department (ED) utilization by renal dialysis (RD) patients, a prospective study was conducted of dialysis patients presenting to the ED of a regional dialysis center. The most common presenting complaints were shortness of breath (SOB), chest pain, abdominal pain, and vomiting; the most common diagnoses were congestive heart failure, chest wall pain, and electrolyte abnormalities. Interventional dialysis (ID), defined as emergent dialysis required to treat the patient's presenting complaint, was required for 30 patients, with the most common presenting complaints of these patients being shortness of breath, weakness, and chest pain. Only SOB was statistically significant in predicting the need for ID (P less than 0.001), with a positive predictive value of 0.63 and a negative predictive value of 0.85. Prehospital implications of these data suggest that RD patients with a chief complaint of SOB should be transported directly to a facility capable of dialysis on an emergent basis.

Six electrical workers accidentally exposed to degradation products of sulphur hexafluoride (SF6) during electrical repair work were followed up for one year. One degradation product, sulphur tetrafluoride (SF4), was identified from worksite measurements. Unprotected exposure in an underground enclosed space occurred for six hours over a 12 hour period. Initial symptoms included shortness of breath, chest tightness, productive cough, nose and eye irritation, headache, fatigue, nausea, and vomiting. Symptoms subsided when exposure was interrupted during attempts to identify the cause of the problem. Although exposure ended after several hours, four workers remained symptomatic for between one week and one month. Pulmonary radiographic abnormalities included several discrete areas of transitory platelike atelectasis in one worker, and a slight diffuse infiltrate in the left lower lobe of another. One worker showed transient obstructive changes in tests of pulmonary function. Examination at follow up after one year showed no persistent abnormalities. Preliminary data from this paper were presented at the VIIth international pneumoconioses conference. Pittsburgh, PA, August 1988.

A murine anti-idiotypic monoclonal antibody (mAb), F1, (IgG2a) was produced against the variable part of the T-cell receptor for antigen (Ti, alpha/beta) on the tumor cells of a patient with T-cell chronic lymphatic leukemia (CD3+,8+,4-). The molecular weight of the protein reactive with mAb F1, comodulation and coprecipitation with anti-CD3 antibody, and the restricted tumor-cell reactivity strongly support the anti-idiotypic nature of mAb F1. MAb F1 also stained less than or equal to 4% of peripheral blood lymphocytes of healthy donors. MAb F1 did not stimulate the tumor cells to DNA synthesis, but stimulated a fraction of the normal peripheral blood lymphocytes, mAb F1 did not mediate antibody-dependent cellular cytotoxicity or complement lysis to any significant degree in vitro. Three infusion of 1-10 mg anti-idiotypic mAb were given over a period of 4 weeks. The plasma half-life for mAb F1 was 3 h in the first 2 h after infusion and 44 h from 2 h to 120 h after infusion. After each treatment a rapid decrease of circulating tumor cells was seen. During the observation period an 80% reduction of the total circulating tumor cells was noted. After the second infusion, IgM and IgG antimouse antibodies were detected. Side-effects from therapy were fever, chills, nausea, vomiting, diarrhea, tachycardia, increase in systolic blood pressure and shortness of breath. Thus, in T-cell malignancies a major reduction of circulating tumor cells can be accomplished by low doses of anti-idiotypic mAb. Anti-idiotypic mAb might be a therapeutic agent of significant importance.

A 55-year-old woman with common variable immunodeficiency and mild chronic obstructive lung disease received 3 units of plasma as immunoglobulin replacement therapy. During the administration of the final unit, her temperature rose 1 degree C, with no other observable symptoms. Fifteen minutes later she developed shortness of breath without nausea, vomiting, rash, or pruritus. In 30 min she lost consciousness, was breathless, and cyanotic. Resuscitative efforts failed. Autopsy failed to pinpoint a cause of death. There was no evidence of ABO or Rh incompatibility, bacterial contamination, or hemolysis. There were no neutrophil, platelet or IgA antibodies detectable in the patient or the 3 plasma donors. There were no lymphocytotoxic HLA antibodies in the patient or two of the plasma donors. The third donor had HLA-B35 lymphocytotoxic antibodies that did not agglutinate or aggregate neutrophils. The patient's HLA type was A2, A3; B35, B40. Lymphocytotoxic crossmatches using lymphocytes of the patient were positive with plasma from the third donor but negative with the other two. An eluate prepared from post-mortem lung parenchymal tissue was cytotoxic to 7 of 8 panel lymphocytes positive for the HLA-B35 antigen but not with cells lacking B35. The implicated plasma donor was healthy with a history of 6 pregnancies. This case report illustrates the potential hazard of transfusion of plasma containing HLA antibodies.

It is generally agreed that bicarbonate dialysate is preferable to acetate dialysate, but the major limiting factors of high cost and technical difficulty in maintaining its stability for prolonged periods preclude its widespread use. The procedure developed by the authors stabilizes bicarbonate dialysate for up to 4 days, rendering bicarbonate dialysate feasible for routine out-patient use. HCO3 dialysate is produced in our dialysis unit after an initial investment of $10,000.00, at a cost per 4-h treatment of $1.22 at a dialysate flow of 500 cc/min. One hundred fifty-one chronic dialysis patients participated in an 18-week study to evaluate clinical symptomatology when bicarbonate was substituted for acetate as the dialysis base buffer. Evaluation of each dialysis treatment (total of 8,183 treatments) consisted of both subjective and objective criteria (vomiting, angina, cramps, hypotension, and frequency of use of mannitol, hypertonic saline, and nitroglycerine). The patients were unaware of the change in dialysate solutions. There was a significant reduction (p less than 0.001) in the incidence of vomiting, cramps, hypotension, nausea, flushing, and the use of mannitol and hypertonic saline during bicarbonate dialysate treatment compared with acetate dialysate. Shortness of breath, angina, mental confusion, and paresthesias were not statistically changed. Although the method of HCO3 dialysate production is associated with occasional higher bacterial count than currently recommended by AAMI standards, no adverse reactions were observed in patients treated with standard efficiency dialyzers. It is concluded that the process for incenter HCO3 production is safe, economical, and better tolerated than acetate dialysate.

Adverse reactions to ophthalmic patients during 9909 fluorescein angiographies during 9 years were registered. Nausea (4.6%) and vomiting (1.3%) were the most common untoward reactions. Allergic skin manifestations occurred in 48 patients, and 5 patients complained of shortness of breath. 56 patients (0.6%) felt dizzy during or immediately after the investigation. Nine patients complained of chest pain, three of whom developed myocardial infarction. Sixteen patients collapsed during the procedure. One healthy male, 42-year-old, collapsed after the injection of fluorescein during angiography, and electrocardiogram showed an asystole of 24 seconds. Otherwise, the electrocardiograms registered on 100 consecutive patients did not reveal any systematic changes in heart rate or rhythm during fluorescein angiography.

Thirty-two workers in an electroplating plant accidently drank water contaminated with nickel sulfate and chloride (1.63 g Ni/liter). Twenty workers promptly developed symptoms (e.g., nausea, vomiting, abdominal discomfort, diarrhea, giddiness, lassitude, headache, cough, shortness of breath) that typically lasted a few hours but persisted 1-2 days in 7 cases. The Ni doses in workers with symptoms were estimated to range from 0.5 to 2.5 g. In 15 exposed workers who were tested on day 1 postexposure, serum Ni concentrations ranged from 13 to 1,340 micrograms/liter and urine Ni concentrations ranged from 0.15 to 12 mg/g creatinine. Ten subjects (with initial urine Ni concentrations greater than 0.8 mg/g creatinine) were hospitalized and treated for 3 days with intravenous fluids to induce diuresis, resulting in a mean elimination half-time (T1/2) for serum Ni of 27 hours (SD +/- 7 hour), which was significantly shorter (p less than .001) than the mean T1/2 of 60 hours (SD +/- 11 hours) in 11 subjects who did not receive intravenous fluids. Laboratory tests showed transiently elevated levels of blood reticulocytes (N = 7), urine albumin (N = 3), and serum bilirubin (N = 2). All subjects recovered rapidly, without evident sequellae, and returned to work by the eighth day after exposure.

Alcoholic ketoacidosis is a frequently encountered metabolic disturbance that follows a prolonged intake of ethanol. Following a brief duration of abstinence, patients typically present with vomiting, abdominal pain, and shortness of breath. Examination reveals Kussmaul breathing, variable volume loss, and coincident manifestations of chronic alcohol usage. Characteristic laboratory findings include anion-gap metabolic ketoacidosis, normal serum glucose, and zero ethanol levels. Phosphate measurements may be depressed, particularly after institution of therapy. Intravascular volume restitution, delivery of dextrose, attention to electrolytes, and discovery of alcohol-related illnesses are the mainstays of therapy.

Subacute carbon monoxide poisoning is commonly misdiagnosed as an influenza-like viral illness. All patients presenting to the triage nurse at University Hospital with flu-like symptoms during February 1985 were asked to give blood samples for carboxyhemoglobin determination. Fifty-five patients (10% of those eligible) with headache, dizziness, nausea, vomiting, diarrhea, weakness, general malaise, or shortness of breath were enrolled in the study. Carboxyhemoglobin levels ranged from 0 to 21%. Thirteen patients (23.6%) of this self-selected subgroup had carboxyhemoglobin levels greater than or equal to 10%. There was no statistically significant difference in carboxyhemoglobin levels between smokers and nonsmokers. More patients using wood heat had elevated carboxyhemoglobin levels than patients using any other form of heating (P less than .05). No patient with a carboxyhemoglobin level greater than or equal to 10% was diagnosed as having subacute CO poisoning by emergency physicians. Physicians must seek out the possibility of CO toxicity in patients with flu-like illness, particularly in inner-city populations during the heating months. Fundoscopy and COHb levels may be useful in selected cases to correctly diagnose patients and avoid a return to a hazardous environment with potentially fatal consequences.
