A multicentre study of IL2 and IFN alpha has been performed in 58 patients with metastatic melanoma. The scheme consisted of IL2 3.0 BRMP MU/m2/d as a continuous infusion for 4 d combined with subcutaneous administration of IFN alpha 6 MU/m2/d, day 1 + 4. The cycle was repeated every 2 weeks for a maximum duration of 26 weeks. 54 patients were evaluable for response. One (2%) achieved a complete and 10 (19%) a partial response. 19 (35%) patients were stable and 24 (44%) showed progressive disease. Common side-effects included fever, chills, fatigue, skin rash, anorexia, nausea and diarrhoea. Hypothyroidism was noted in 10% of the patients. These results show that this regimen of IL2 and IFN alpha is active but, in contrast to what could be expected, not superior to IL2 alone possibly due to suboptimal dosing. In an ongoing study in Rotterdam and Nijmegen, a more intense schedule was chosen, consisting of three daily i.v. doses of IL2 4.5 BRMP MU/m2 and IFN alpha 3.0 MU/m2 for 5 d. This regimen is repeated at intervals of 3 weeks for a total of three cycles. Presently, nine patients have been entered. One patient achieved a complete response, four a partial response (overall 56%), three had stable disease and one progressed. Toxicity was severe and treatment was prematurely stopped in five patients: myocardial infarction (one patient), atrial fibrillation (one patient), negative T waves and myocardial hypokinesia (one patient) and psychosis (two patients). This regimen can only be justified if the therapeutic results are superb, which has yet to be awaited.

In a prospective open study, seven patients with persistent pustulosis palmaris et plantaris were treated with oral Cyclosporin A (CsA). Clinical efficacy was assessed on a semi-quantitative 0-4 point scale for erythema, desquamation, induration and pustulation. CsA controlled skin lesions in doses ranging from 1.1 to 6.1 mg/kg body weight/day. Clinical side effects included renal impairment, nausea and tiredness. Rapid recurrence of the skin lesions was observed on withdrawal or insufficient treatment with the drug.

The effects of dexmedetomidine, an alpha 2-adrenoceptor agonist, on vigilance, thiopental anesthetic requirements, and the hemodynamic, catecholamine, and hormonal responses to surgery were investigated in healthy (ASA physical status 1) women scheduled for dilatation and curettage (D & C) of the uterus. Fifteen minutes before induction they received single iv doses of either dexmedetomidine (0.5 micrograms/kg; n = 19) or saline (n = 20) in a double-blind fashion. Anesthesia was induced with thiopental and maintained with N2O/O2 (70/30%) and thiopental. Dexmedetomidine was well tolerated and no serious drug-related subjective side-effects or adverse events were observed. The most prominent subjective effects were fatigue and decreased salivation. The total amount of thiopental needed to perform D & C of the uterus was reduced approximately 30% (from 456 +/- 141 mg [mean +/- SD] after saline to 316 +/- 79 mg after dexmedetomidine). This was mostly due to a smaller induction dose in the group receiving dexmedetomidine. Dexmedetomidine appeared to improve the recovery from anesthesia as measured by visual analogue scales (VAS) on fatigue and nausea. The plasma concentration of norepinephrine was decreased by 56% after dexmedetomidine implying decreased sympathetic nervous activity. Systolic and diastolic blood pressure were moderately reduced after dexmedetomidine administration. The authors conclude that dexmedetomidine preanesthetic medication decreases thiopental anesthetic requirements and improves the recuperation from anesthesia with no serious hemodynamic or other adverse effects. Further studies in patients undergoing more stressful surgery are indicated.

beta-receptor antagonists have for many years been considered appropriate alternatives in the primary management of mild to moderate hypertension. Generally, they have been shown to be safe with a low frequency of serious side-effects. Among the predictable and usually doserelated side-effects are bradycardia, bronchospasm, hypotension, muscle fatigue and cold extremities. Examples of unexpected side-effects are gastrointestinal symptoms such as nausea and disturbed intestinal motility, skin reactions, sexual dysfunction, as well as effects related to the central nervous system (CNS) such as emotional disturbances. The CNS-related side-effects, the mechanisms of which are unclear, consist of subtle effects on general well-being, decreased initiative, a depressed frame of mind and disturbed sleep. Generally, however, beta-blockers in therapeutic dosages do not affect the qualitative functions of the brain. Thus, all beta-blockers on the market seem to have high benefit-risk ratio, but independent of their physiochemical properties and pharmacodynamic profile, they seem to cause side-effects to about the same extent. The results so far available have been obtained by primarily using objective methods. Further comparison has now been initiated using documented subjective methods to investigate whether the objectively documented differences are of any clinical relevance to the patient's quality of life. Although it cannot be claimed with certainty, nonselective beta-blockers seem to cause CNS-related side-effects to a greater extent than beta 1-selective blockers. Differences in the degree of hydrophilicity of the beta-blocker are apparently of no clinical relevance in this respect.(ABSTRACT TRUNCATED AT 250 WORDS)

A phase I trial of natural human beta-interferon (nHuIFN-beta) was initiated to evaluate its biological activity, maximum tolerated dose, and toxicity in patients with refractory malignancies. nHuIFN-beta was administered to successive groups of 4-6 patients as an i.v. bolus on days 1 and 4, for 4 consecutive weeks. Dose levels were 0.1, 1.0, 10, 30, 60, 100, and 200 x 10(6) units/m2. Thirty-five patients were entered, and 34 patients were evaluable for toxicity, immunomodulatory, and antitumor effects. Toxicity was mild to moderate and included fever and chills, fatigue, arthralgias, nausea, transient renal and hepatic dysfunction, and leukopenia. No dose-limiting toxicity was observed, and no responses were seen. Significant immunological changes included the following: an increase in natural killer activity on day 5 when compared to pretreatment values (P less than 0.01) and an increase in activated T-cells (CD3+/HLA-DR+) with increasing doses of nHuIFN-beta (P less than 0.01). Pharmacokinetic data demonstrated a short alpha half-life of 12.1 +/- 2.5 (SE) min and a beta half-life of 129.7 +/- 14.7 min. Neutralizing serum antibodies were detected in 2 of 27 patients receiving nHuIFN-beta. In conclusion, toxicity of nHuIFN-beta given twice weekly was moderate, and further dose escalation is possible. The immunological changes and pharmacokinetic behavior of nHuIFN-beta resemble those reported with rHuIFN-beta ser.

In June 1983, an outbreak of waterborne giardiasis occurred in a group of 93 university students and faculty participating in a geology field course in Colorado. All cases occurred in one subgroup of persons who were heavily exposed to untreated stream water on a field trip, and the risk of illness was strongly related to the amount of untreated stream water consumed. The median incubation period from a brief exposure to the first symptom was 7 days. The authors compared symptoms and stool sample results among 31 Giardia-positive persons in the exposed group and 36 Giardia-negative participants in an unexposed group to assess several case definitions for acute giardiasis. Diarrhea, abdominal cramps, flatulence, foul-smelling stools, nausea, excessive tiredness, bloating, anorexia, and chills were each significantly more common in the first group than in the second. A giardiasis case definition of 5 days or more of diarrhea--the definition used in many epidemiologic studies of giardiasis--had a specificity of 100 percent but a sensitivity of only 32.2 percent compared with a definition based on results of stool examinations. When a case was defined as an illness lasting 7 days or more, with a combination of two or more of six symptoms (diarrhea, flatulence, foul-smelling stools, nausea, abdominal cramps, and excessive tiredness), sensitivity rose to 73 percent, with a specificity of 88 percent. Such a case definition may be an improvement over that of 5 days of diarrhea, especially in outbreaks where there is good laboratory documentation that Giardia is the etiologic agent. The definition should be validated in other outbreaks and in situations where giardiasis must be distinguished from gastrointestinal disease caused by other agents.

Decompression sickness (DCS) is a well-known hazard of exposure to significant variations in ambient pressure. The diagnosis and management of DCS is frequently a source of confusion. Although the majority of cases are manifested by joint or limb pains (Type I DCS), patients may present with a wide array of symptoms, such as neurologic deficits, headache, fatigue, nausea, and respiratory difficulty. A thorough knowledge of the differential diagnosis and a strong index of suspicion are crucial to the proper management of DCS. Presented herein are two cases of altitude-related DCS which were confused initially with a viral syndrome. A discussion of the symptoms of DCS is included.

Digitalis intoxication is among the most common serious adverse drug reactions in clinical medicine. While the recent development of a radioimmunoassay to accurately measure serum concentrations of digoxin has been of assistance, digitalis intoxication remains a difficult diagnosis to make with certainty. The difficulty in diagnosing digitalis intoxication arises from the nonspecificity of its associated signs and symptoms. The most common symptoms include fatigue, weakness, nausea, and anorexia. These symptoms can occur with many illnesses other than digitalis intoxication. Similarly, the electrocardiographic disturbances caused by cardiac glycosides may be nondiagnostic. The arrhythmias commonly associated with digitalis toxicity are often nonspecific and can be a reflection of the patient's underlying heart disease. The measurement of serum digoxin levels is useful, but studies have demonstrated overlap of the levels between groups with and without toxicity. Due to the modulation of the cardiac effects of digitalis glycosides by such clinical variables as underlying myocardial or renal disease, electrolyte and acid-base imbalances, and other factors, the correlation of toxicity with particular serum digoxin concentrations may vary. Because of the inherent difficulties in confirming the diagnosis of digitalis intoxication in some cases, digoxin-specific Fab antibodies may play a role as a diagnostic tool. Certainly, digoxin-specific Fab antibodies play a significant part in the treatment of digitalis intoxication. Fab antibodies have been successfully used to reverse the effects of digoxin, digitoxin, and oleander poisoning. These antibodies are useful in the treatment of acute and chronic digitalis intoxication in all age groups, including geriatric and pediatric populations.(ABSTRACT TRUNCATED AT 250 WORDS)

A cross sectional survey on the prevalence of acute pyrethroid poisoning in cotton farmers was conducted in 1987 and 1988. A total of 3113 pyrethroid spraymen (2230 men (71.6%) and 883 women (28.4%] were interviewed after spraying and followed up for 72 hours. Adverse effects of pyrethroid exposure were found in 834 of them (26.8%) manifested as abnormal facial sensations, dizziness, headache, fatigue, nausea, or loss of appetite. Only 10 subjects, who developed significant systemic symptoms and had signs of listlessness or muscular fasciculation, were diagnosed as having mild occupational acute pyrethroid poisoning with a prevalence of 0.31% in subjects exposed to pure pyrethroids and 0.38% in subjects exposed to pyrethroid organophosphate mixtures. Measurements of pyrethroid concentrations in the air of the breathing zone, in skin pads, and in urine samples showed that dermal contamination is the main route of exposure to pyrethroids in cotton growers. Preventive measures are recommended.

Tumor necrosis factor (TNF) is a cytokine with pleiotropic biological and antitumor effects in vitro and in mouse models. The immunological effects of the molecule as a single agent, however, have not been well studied clinically. We conducted a Phase I trial of TNF in 53 patients with advanced malignancies in order to determine the biological and clinical effects of TNF when administered as a 30-min i.v. infusion three times/week. Dose levels of TNF ranged from 5 to 275 micrograms/m2; doses of TNF were escalated between patient groups. The most common clinical toxicities of TNF consisted of rigors, anorexia, headache, and fatigue. Dose-limiting toxicity consisted of hypotension, fatigue, and nausea. Four patients treated at the maximally tolerated dose of 225 micrograms/m2 received dexamethasone to determine whether the toxicities of TNF could be ameliorated. No significant differences in hypotension or subjective symptomatology were observed in those patients receiving dexamethasone and those who did not or between injections in which dexamethasone was administered and when it was not. One patient with colorectal carcinoma treated with 50 micrograms/m2 had a partial response lasting about 9 months. Biological responses were evaluated in 8 patients treated at the maximally tolerated dose before therapy and 24 h afterward. TNF significantly (P less than 0.05 for all) enhanced serum beta 2-microglobulin, serum neopterin, and serum interleukin-2 receptor (Tac antigen) levels. Indoleamine 2,3-dioxygenase activity was also increased 24 h following the administration of TNF, although this increase was only of borderline statistical significance (P = 0.07). TNF did not enhance granulocyte bactericidal activity. The expression of cell surface proteins on monocytes, including HLA-DR, HLA-DQ, beta 2-microglobulin, and the Fc receptor, and serum interleukin-1 activity also were not significantly increased by the administration of TNF. Thus, in humans TNF caused biological response modulation with evidence of HLA Class I (beta 2-microglobulin) increase and T-cell (Tac antigen) and monocyte (neopterin) activation.
