Hypercalcemia is one of the most critical complications in patients with malignancy. We have used salmon calcitonin for treatment of hypercalcemia in these patients. The subjects were 49 hypercalcemic patients with various malignancies. Synthetic salmon calcitonin (SCT) was provided by Teikoku Hormone Mfg. Co. Ltd., Japan and 40 MRC units was administered twice daily i.m. or i.v. In 21 of 33 cases treated i.m. and in 8 of 16 cases treated i.v., a serum Ca decrease of more than 2 mg/dl was observed. The hypercalcemia was managed in 59% of patients within 6 days after initiation of the treatment and effective duration was 14 days. On the other hand, ineffective cases treated with a combination of SCT and glucocorticoid or SCT and mithramycin were managed in 57% and 86%. The 50% survival time was 69 days in the effective cases and 23 days in the uncontrolled cases (P less than 0.01). The main causes of death in the ineffective cases were renal insufficiency. On the other hand, in the effective cases, improvements of renal function were observed. The side effects were slight, and nausea and flushing were observed in 24% of cases. These data indicate that SCT is effective for lowering the serum Ca level in hypercalcemic patients with malignancies.

Programmed ventricular stimulation was used to test oral bethanidine sulfate in 10 patients with life-threatening ventricular arrhythmias. These patients had previously documented, recurrent, sustained ventricular tachycardia (VT) and/or ventricular fibrillation (VF) complicating stable heart disease. During control electrophysiologic studies, VT could be induced in all 10 patients: 6 with nonsustained VT, 3 with sustained VT, and 1 with VT/VF. After control, bethanidine 20-30 mg/kg was administered orally and beginning 60 minutes later, programmed ventricular stimulation was repeated. After bethanidine administration, VT could be induced in nine patients; in four, the VT was essentially unchanged from that induced during control studies. In four others, worse VT was induced after bethanidine. The remaining two patients had a potentially beneficial response to the drug. Bethanidine was poorly tolerated: seven patients had symptomatic orthostatic hypotension that persisted for several days despite concurrent protriptyline therapy. Furthermore, in four patients, spontaneous VT or VT/VF occurred 3-8 hours after the last dose. Nausea, vomiting, flushing, and blood pressure elevation were also noted. Bethanidine sulfate in the dosages used usually does not prevent the induction of VT by programmed ventricular stimulation and frequently causes serious toxicity. These findings suggest that the drug would be ineffective and poorly tolerated for long-term therapy in patients with serious ventricular arrhythmias.

Although the exposure of human subjects to prostacyclin (PGI2) infusion has been broad, no systematic approaches have been made in order to investigate the dose-related side effects in patients with angina pectoris and coronary artery disease (CAD). We studied 25 patients with typical chest pain and overt CAD. All patients underwent a cycloergometer stress testing (25 W increments at 2-min intervals). PGI2 was infused in scalar doses up to 10 ng/kg/min. During the infusion 25 patients (100%) had facial flushing, 7 (28%) moderate headache and one (4%) had nausea. In addition, 4 patients experienced the typical chest pain and had significant (greater than or equal to 0.1 mV) ST segment depression at 8.10 ng/kg/min infusion rates. These patients had lower tolerance to exercise (6.7 +/- 1.7 vs. 8.8 +/- 1.9 min; p less than 0.05) and coronary artery lesions more severe than those observed in patients without drug-induced angina pectoris. Our data therefore indicate that PGI2 at therapeutic doses may induce myocardial ischemia in patients with angina pectoris, low tolerance to exercise and severe CAD. In patients with mild to moderate degree of CAD, PGI2 was found to be well tolerated. These findings suggest that patients with angina pectoris and low tolerance to exercise should be excluded from clinical studies directed at elucidating the effectiveness of PGI2 in cardiovascular disorders.

This study evaluated the effect of gastric bypass on the glucose, insulin, vasoactive intestinal peptide (VIP), neurotensin, and motilin response to orally administered glucose in eight morbidly obese patients before and after operation. Preoperatively, all eight patients remained asymptomatic during an oral glucose tolerance test, which showed glucose intolerance and hyperinsulinism. Plasma VIP, neurotensin, and motilin remained below detectable levels for the entire test. At three months following gastric bypass (21% weight loss), all eight patients became acutely ill during a repeated oral glucose tolerance test and had the following symptoms: facial flushing (eight patients), palpitations (eight patients), nausea (seven patients), abdominal fullness (seven patients), pallor (four patients), diaphoresis (two patients), vomiting (two patients), and diarrhea (two patients). Significant release of neurotensin occurred in seven patients while three patients had release of VIP, further implicating these two peptides as part of the pathophysiologic spectrum of the "dumping syndrome."

We questioned 113 patients with subsequently diagnosed sustained ventricular tachycardia (VT) regarding the symptoms that prompted their seeking hospital treatment, eliciting the following: 15% of patients had lost consciousness, 15% had near syncope, 35% had mild lightheadedness and 35% had no cerebral symptoms. Patients with preexisting congestive heart failure or a VT rate of 200 beats per minute or greater more often lost consciousness. Other symptoms included palpitations in 57% of patients, chest pain in 27%, dyspnea in 25%, weakness in 6%, nausea or diaphoresis in 3% each and flushing in 2%. In approximately 50% of patients who had mild lightheadedness or no cerebral symptoms, their condition was incorrectly diagnosed as supraventricular tachycardia based on the absence of severe symptoms during the tachycardia. In some patients, VT may be associated with mild or atypical symptoms. The differentiation of supraventricular from ventricular tachycardia should be based on electrocardiographic criteria and should not be influenced by the nature or severity of a patient's symptoms. The severity of cerebral symptoms is at least partially related to the VT rate and a patient's underlying heart disease.

A patient with gout and schizophrenia is described who during a schizophrenic paroxysm with paranoid-hypochondriac-hallucinatory syndrome attempted to commit suicide and took 200 tablets milurit (20 g). He developed the picture of acute intoxication with nausea, vomiting, profuse diarrhea, abdominal pain, flushing, temperature, collapse manifestations, hepatomegaly, direct hyperbilirubinemia, elevated transaminase, leukopenia, accelerated ESR. After reanimation and infusion therapy, the patient recovered within 4 days and 2 weeks later all blood indices reached the limits of the norm.

Synthetic thyrotrophin-releasing hormone (TRH) given intravenously in doses of 50 mug or more causes a significant rise in serum thyroid-stimulating hormone (TSH) levels but has no effect on serum growth hormone, plasma luteinizing hormone, or plasma 11-hydroxycorticosteroids under carefully controlled basal conditions.The peak TSH response to intravenous TRH occurs at 20 minutes. The mild and transient side effects, which occur only after intravenous TRH, include nausea, a flushing sensation, a desire to micturate, a peculiar taste, and tightness in the chest. There is considerable variability in response to a given dose of TRH in the same subject on different occasions and in different subjects. Oral administration of TRH in doses of 1 mg and above causes a rise in serum TSH, maximal at two hours, a consistent response being obtained at doses of 20 mg and above. A rise in serum protein-bound iodine (P.B.I.) follows that of TSH, a consistent response being observed at 40-mg doses of TRH orally. Measurements of serum TSH after intravenous administration of TRH or of serum TSH or serum P.B.I. after oral TRH should prove useful tests of pituitary TSH reserve.

It is noted that advertisements in medical journals recommend treatment of emotional symptoms in menopausal patients with Premarin (Ayerst brand of conjugated estrogens), Ogen (Abbott brand of piperazine estrone sulfate), or other compounds. There are no acceptable studies proving the usefulness of such combinations for symptoms relating to the menopause and no persuasive evidence to justify use of conjugated or any other type of estrogen in the treatment of emotional symptoms in menopausal women. Vasomotor symptoms, flushing, and sweats respond to estrogens. Symptoms do not recur if treatment is stopped after 1 or 2 years. Systematic or topical use of estrogens fails to promote the appearance of youthfulness. Vaginal pruritus and dyspareunia due to atrophic vaginitis may be relieved by estrogens either applied locally or orally. Libido is not heightened by exogenous estrogens but sufficient androgen doses cause virilization. It is doubtful if osteoporosis is favorably influenced by long-term use of estrogens. Estrogen therapy may cause spotting, menarrhagia, nausea, breast tenderness, or fluid retention. Prolonged use may cause increase in size of uterine fibroids. Personal or even family history of breast or genital cancer are considered contraindications.

Thirteen patients with painful Paget's disease of bone were treated as outpatients with low doses of synthetic salmon calcitonin 22.5-50 mug three times weekly. Treatment produced full remission of pain in a mean time of 5.5 weeks and a mean depression of serum alkaline phosphatase activity of 33%.The interval before symptomatic relief could not be predicted from the variables studied. The ultimate fall in serum alkaline phosphatase activity, however, could be predicted from the initial levels and from the early rate of decrease (P < 0.001). Biochemical resistance to treatment, which occurred in three cases, could be related to the dose and duration of treatment.Prolonged remissions of pain may occur which are not related to biochemical remission, to the dose of calcitonin, or to the duration of treatment. The side effects attributable to salmon calcitonin were transient nausea (in nine patients), transient flushing (in four), diarrhoea (in two), and rash (in one) though in only one patient did treatment have to be withdrawn prematurely because of these effects.

The efficacy of intravaginal administration of prostaglandin F2 alpha (PGF2alpha) in induction of abortion was determined in a clinical trial of 16 gravidas aged 21-38, parity 0-4, between the 6th-11th weeks of pregnancy. PGF2alpha tablet (50 mg) was inserted into the posterior fornix of the vagina and repeated at 1-2 hour intervals; dose range varied from 50-250 mg. Slight to severe labor-like pain was felt by all patients in the lower abdominal region 20 minutes-4 hours after PGF2alpha administration. Vaginal bleeding occurred within 30 minutes-8 hours. In all but 1 case, the fetus and the villi were expelled broken into small pieces. All 16 patients aborted, 7 completely and 9 incompletely. This form of administration is deemed efficacious as 3 patients aborted completely within 5 hours and 4 aborted completely between 15-18 hours. Bleeding in most cases occurred following the onset of abdominal pain, 30 minutes-8 hours after treatment. In another clinical trial, the efficacy of intravaginal administration of PGF2alpha in inducing menstruation was tested in 10 volunteers aged 31-40. Either 50 or 25 mg PGF2alpha tablets were used. The patients recorded their basal body temperature (BBT) every morning. Menstruation was successfully induced in 6 of 10 patients. 6 patients treated 2-3 days before the expected date of menstruation had menstrual-like bleeding 1-9 hours after PGF2alpha administration. 3 patients treated 5, 7, and 13 days (a day before BBT shift) before the expected date of menstruation did not have vaginal bleeding. 1 patient, with monophasic BBT who was treated 3 days before the expected menstruation, did not have menstrual bleeding. Amount of induced flow was more or less the same in most patients; duration of flow was normal in all cases. The mechanism of action of PG in menstruation induction is not known. The authors speculate that PGF2alpha mechanically stimulates separation of the superficial endometrium from the remainder of the uterine wall when the endometrium is in the premenstrual state. Side effects noted were nausea, diarrhea, pyrexia, slight flushing of the face, and headache.
