Experimental and clinical experience with compounds containing antimony have shown that the trivalent compounds are generally more toxic than the pentavalent ones. APT can cause severe pain and tissue necrosis and is therefore not given by intramuscular or subcutaneous injection. APT has the actions and uses of AST, but it is less soluble and more irritating than the sodium salt which is therefore more suitable for intravenous use. Trivalent antimony compounds are toxic when used topically. Adverse effects are similar for all trivalent compounds, and include nausea, vomiting, weakness and myalgia, abdominal colic, diarrhoea, and skin rashes, including pustular eruptions. Hypersensitivity reactions also occur. Respiratory symptoms include cough, dyspnoea, and chronic lung changes. Cardiotoxicity is the most important and may produce arrhythmias, myocardial depression and damage, Stokes-Adams attacks, heart failure, and cardiac arrest. Hepatic damage and necrosis, as well as blood dyscrasias, may occur. Toxic effects on the kidney may follow chronic use. Continuous treatment with small doses of antimony may give rise to symptoms of subacute poisoning, similar to those of chronic arsenic poisoning, due to accumulation of antimony in the body, especially if trivalent compounds are used, because of their long biological half-lives. Reproductive disorders and chromosome damage have been reported; antimony compounds are, therefore, potentially toxic to reproduction and have mutagenic, and oncogenic potential. Antimony compounds should, therefore, not be used during pregnancy or in the presence of hepatic, renal, or heart disease. Pentavalent antimony preparations especially the organic compounds, together with non-metallic synthetic preparations, such as the diamidines, have now replaced APT for use in leishmaniasis. Because of the toxicity of antimony compounds, investigations have been undertaken to reduce their adverse effects by combining them with chelating agents. These preparations appear to have reduced the toxic effects of antimony without affecting the efficacy of the preparations. Liposome-encapsulated antimony products have, more recently, been shown to be much less toxic because of the reduced dose of the antimony compound required for effective therapy. The historical uses of antimony were based on the belief that the topical and systemic adverse effects, for example, skin eruptions and diarrhoea and vomiting, were signs that the condition being treated was responding by being brought to the surface to relieve congestion at the diseased area. There is no evidence in topical use, but there is evidence that such use can cause severe reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

The possibility that the central and autonomic nervous systems might be involved in the control of intestinal absorption was assessed by measuring the effect of physical stress (cold-induced pain) on jejunal transport in 13 healthy subjects. Using a triple-lumen perfusion technique to determine jejunal absorption, cold pain significantly reduced net water absorption from 34.9 to 15.7 ml/30 cm.50 min (p less than 0.005), net sodium absorption from 2.6 to 0.2 mEq/30 cm.50 min (p less than 0.005), and net chloride absorption from 2.2 to 0.6 mEq/30 cm.50 min (p less than 0.02). These changes were associated with an elevation of blood pressure and plasma norepinephrine during cold pain. During the period following cold pain, systolic blood pressure remained significantly elevated and net jejunal water absorption significantly reduced. These results suggest that physical stress can influence jejunal absorption of salt and water in humans and support the possibility that the central and autonomic nervous systems have a physiologic role in the control of intestinal function.

In a clinical trial carried out in 34 pregnancy women Enzaprost F 4 (prostaglandin F2-alpha) was administered into the uterus to cause uterine contractions in the 2nd and 3rd trimesters. The indications for the treatment were: 1. membrane rupture in 20 cases between the 21st and 26th weeks of pregnancy; 2. fetal death in 12 cases between the 24th and 34th weeks of pregnancy, and 3. induced abortion for medical reasons in 2 cases of primiparae in the 2nd trimester. Enzaprost was administered in physiological salt solution in doses of 2-5 mg with a total dose of 9-22 mg (average 18.5 mg). Contractions appeared within 15-30 minutes in groups 1 and within 20-30 minutes in groups 2 and 3. Abortions in the three different groups began 10.2, 11.5, and 6.0 hours after administration in primiparae and 7.3 and 8.2 hours, respectively, after treatment in groups 1 and 2 in women other than primiparae. Oxytocin had to be administered additionally in 3 cases in groups 1 and 2. The method proved to be safe and effective, side effects occurred in 6 cases (17.6%) consisting of cardiac pain, nausea, tachycardia, and increased systolic pressure.

Mafosfamide is a new oxazaphosphorine that breaks down spontaneously into 4-hydroxy-cyclophosphamide. A phase I trial with cyclohexylamine and lysine salts of mafosfamide was carried out in 16 patients, using weekly IV perfusion. Dose-limiting toxicities were not hematological, but consisted in the development of severe pain along the vein during administration. A particular mucosal syndrome with sneezing and conjunctivitis was seen only after administration of the lysine salt. The dose of 700 mg/m2 per week represents the maximum tolerated dose with this weekly schedule.

A patient with hydrofluoric acid burns involving only 8% of his body surface area died from intractable cardiac arrhythmia secondary to the depletion of ionized calcium by fluoride ion. For burns of this type, immediate subcutaneous injection of 10% calcium gluconate into the burn wound is recommended and the dose given should be titrated to the relief of local pain. Immediate debridgement of the burn wound also can decrease the treacherous aspect of the circulating fluoride ion, which binds to calcium to form an insoluble salt, effectively removing the calcium ion from any physiologic interaction.

A case of ticarcillin-induced hemorrhagic cystitis is presented, and the literature on drug-induced hemorrhagic cystitis is reviewed. A 12-year-old white boy with cystic fibrosis was hospitalized for an exacerbation of his pulmonary disease. Laboratory tests on admission showed an elevated white blood cell (WBC) count, 10-20 WBCs per high-power field (HPF) in urine, and normal BUN and serum creatinine. The patient was given ticarcillin i.v. (as the disodium salt) (final dosage of 320 mg/kg/day) in divided doses every six hours and netilmicin i.v. (as the sulfate salt) (final dosage of 4 mg/kg every eight hours). On day 7 the patient complained of painful urination, and urinalysis showed a 10-20 WBCs/HPF and 2-5 red blood cells (RBCs)/HPF. Two days later, the patient had gross hematuria, and urinalysis revealed 10-20 WBCs/HPF and 10-20 RBCs/HPF. Ticarcillin and netilmicin were discontinued and the patient's symptoms abated within 48 hours. Repeat urinalysis on day 11 showed no RBCs and 10-20 WBCs/HPF, with no casts or protein. Three months later, the patient was again hospitalized for an exacerbation of his cystic fibrosis. He was placed on tobramycin sulfate i.v. and ticarcillin i.v. (340 mg/kg/day). After the fourth dose of ticarcillin, the patient again complained of urinary pain and frequency and also reported gross hematuria. Urinalysis showed bacteria, 2-5 WBCs/HPF, and 5-10 RBCs/HPF; however, urine cultures were negative. Ticarcillin was discontinued and cefoxitin sodium i.v. was started. The patient's symptoms resolved within 36 hours, and a urinalysis on the fourth hospital day was normal.(ABSTRACT TRUNCATED AT 250 WORDS)

Ketorolac tromethamine[(+/-)-5(benzoyl)-2,3-dihydro-1N-pyrrolizine-1-carboxylic acid tris hydroxymethylaminomethane salt] is a highly potent member of a new class of compounds having analgesic and anti-inflammatory activity. When given orally in tests involving underlying inflammation it was a potent analgesic, whereas it was inactive in tests for narcotic activity. It was also highly active orally in rat models of acute and chronic inflammation and pyresis. These properties are mediated primarily via the compound's potent prostaglandin cyclooxygenase inhibitory activity. The agent elicited mild CNS and cardiovascular activity only at doses far in excess of those required for analgesic and anti-inflammatory activity. A single 10 mg tablet given orally to human volunteers following surgery provided pain relief equivalent to that provided by 10 mg of morphine given intramuscularly. When given intramuscularly to rabbits (0.25 ml of a 0.31-5% solution) or man (3 ml of a 1-3% solution), no drug-related irritation or changes in creatine phosphokinase were seen. Solutions (less than or equal to 0.5%) applied to the eyes of animals and man were not irritating. When applied topically in rat and rabbit models of ocular inflammation, less than or equal to 0.5% solutions of ketorolac tromethamine inhibited the inflammatory response.

In the double-blind study reported here the authors were able to confirm the time- and dose-related effect of dilatation of the cervix by means of the new prostaglandin-E2 derivative (9-deoxo-16, 16-dimethyl-9-methylene-PG-E2-potassium salt) as compared to placebo. In spite of the short preoperative duration of action of three hours it was observed that half of the patients treated with the prostaglandin derivative vomited once or several times. The authors therefore consider that administration of the prostaglandin vaginal suppository is only justified in cases with a high risk of cervical injury, and in primiparae undergoing termination under local anesthesia. In 38 patients termination was performed by means of direct cervicomyometrial analgesia. With one exception they approved of chemical dilatation of the cervix in spite of the side-effects, assuming that it would result in less intraoperative pain.

Mafosfamide-cyclohexylamine is a new oxazaphosphorine derivative. It was chosen for phase-I clinical testing because of an expected higher therapeutic index and lack of complete cross resistance in animal tumors compared to cyclophosphamide. The schedule consisted of a single iv dose repeated every three weeks. The compound was found to cause as it's dose limiting toxicity severe pain along the injected vein and acute irritation of mucous membranes. The maximal tolerated dose was around 1000 mg/m2 given as a slow infusion over 2-3 hours. Hematological toxicity was mild. A limited phase-I study with the lysine salt of mafosfamide showed an identical type of toxicity. Mafosfamide given iv in a high-dose intermittent schedule is of little interest for further clinical trials. It is probable, that the severe venous pain and the mucosal irritation are caused by the high local concentration of 4-hydroxy-cyclophosphamide or by a metabolite. An oxazaphosphorine derivative undergoing slower hydrolysis therefore leading to lower active drug concentrations within the injected vein may be more promising.

Data is reviewed on premenstrual symptoms which have been related to high suicide and accident rates, employment absentee rates, poor academic performance and acute psychiatric problems. A recent study of healthy young women indicated that 39% had troublesome premenstrual symptoms, 54% passed clots in their menses, 70% had cyclical localized acneiform eruptions and only 17% failed to experience menstrual pain. Common menstrual disorders are classified as either dysmenorrhea or the premenstrual syndrome. Symptoms for the latter usually begin 2-12 days prior to menstruation and include nervous tension, irritability, anxiety, depression, bloated breasts and abdomen, swollen fingers and legs, headaches, dizziness, occasional hypersomia, excessive thirst and appetite. Some women may display an increased susceptibility to migraine, vasomotor rhinitis, asthma, urticaria and epilepsy. Symptoms are usually relieved with the onset of menses. While a definitive etiological theory remains to be substantiated, symptomatic relief has been reported with salt and water restriction and simple diuretics used 7 to 10 days premenstrually. Diazapam or chlordiazepoxide treatment is recommended before oral contraceptive therapy. The premenstrual syndrome may persist after menopause, is unaffected by parity, and sufferers score highly on neuroticism tests. Primary or spasmodic dysmenorrhea occurs in young women, tends to decline with age and parity and has no correlation with premenstrual symptoms or neuroticism. Spasmodic or colicky pain begins and is most severe on the first day of menstruation and may continue for 2-3 days. Treatment of dysmenorrhea with psychotropic drugs or narcotics is discouraged due to the risk of dependence and abuse. Temporary relief for disabling pain may be obtained with oral contraceptives containing synthetic estrogen and progestogen but the inherent risks should be acknowledged. Both disorders have been correlated to menstrual irregularity. Amenorrhea in many women may be precipitated by simple psychological events such as leaving home, while severely stressful events produce a higher incidence. Unless a physiological factor such as malnutrition is operating, menses usually recur spontaneously within a few months. Amenorrhea is a constant feature of anorexia nervosa and may precede related attitudes toward eating and body weight. This syndrome is best regarded as a chronic and often severe neurotic disorder requiring combined physiological and psychological treatment, although some evidence exists to indicate an endocrine disorder. Extensive basic research is needed on the complex relationship between the neuroendocrine system and emotion.
