Acetic acids bearing the 1-phenyl-1H-indazole nucleus with analgesic and antiinflammatory activity.

The synthesis of [(1-phenyl-1H-indazol-4-yl)oxy]acetic acid (IV), (1-phenyl-1H-indazol-4-yl)acetic acid (IX) and (1,5,6,7)tetrahydro-1-phenyl-4H-indazol-4-iminooxy)acetic acid (XIII) starting from 1,5,6,7-tetrahydro-1-phenyl-4H-indazol-4-one (I) is described. These compounds showed a good antiinflammatory activity in rats, and an analgesic activity in mice similar or comparable to that of indomethacin.

Effect of naloxone on plasma concentrations of prolactin and LH in lactating sows.

Six lactating sows were injected through an indwelling vena cava cannula with naloxone (2.5 mg/kg body weight) on Day 15 post partum. Blood samples were collected through the cannulas at 10-min intervals for 8 h before and 10 h after naloxone administration. Plasma prolactin and LH concentrations were measured by radioimmunoassay. Naloxone caused a marked suppression of plasma prolactin concentrations lasting 4-6 h. LH concentrations were also affected by naloxone: LH rose to reach maximum values 20-50 min after naloxone treatment. Pretreatment values were recorded 200-300 min after the treatment. These results indicate that endogenous opioids are involved in causing the endocrine patterns occurring during lactation, i.e. high prolactin and low LH concentrations.

Planned release dihydroergotamine in common migraine and "tension-vascular headache": multicentre clinical trial.

The antimigraine efficacy of dihydroergotamine methanesulphonate in the pharmaceutical form of planned release capsules has been evaluated. Forty-nine subjects were treated, 39 suffering from common migraine 10 from tension vascular headache, for a period of 90 days, with an oral dose of 15 mg twice daily. The product was found to be efficacious in 71% of the common migraine cases, while unsatisfactory or nil results were obtained in the remaining 29%. In the tension-vascular headache cases, efficacy was 40% compared to 60% unsatisfactory or nil results. Tolerance was good in 43 cases, while transient digestive disorders (nausea and vomiting) occurred in 6; in 2 cases the treatment had to be withdrawn for allergic erythema. The results demonstrate that the drug is indicated in cases of common migraine, while it does not appear to significantly influence the course of attacks of tension-vascular headache.

Monitoring of a long survival myeloma patient.

Monitoring with anti-idiotypic sera has been applied to identify tumoral cells in a myeloma patient still alive in complete remission 9 years after diagnosis. Monoclonal plasma cells displayed a labeling index that decreased in complete remission below 1%. The great majority of B lymphocytes belonged to the tumoral clone even in complete remission and were therefore not affected by conventional chemotherapy. Some aspects of this myeloma patient are discussed in the light of these immunologic and kinetic findings. In addition, it is suggested that the therapeutic management of the complete remission should be re-examined, by considering a lymphocytolytic therapy.

Pseudohypoparathyroidism: inheritance of deficient receptor-cyclase coupling activity.

Pseudohypoparathyroidism, type I (PHP-I) is an inherited disorder of primary resistance to multiple hormones that work by stimulating adenylate cyclase. In an attempt to clarify the mode of inheritance of PHP-I, we measured the activity of the N protein, a receptor-cyclase coupling component, in erythrocyte membranes. Erythrocyte N-protein activity was reduced by approximately 50% in erythrocytes of 15 PHP-I patients and was normal in 19 of their clinically normal first degree relatives. Reduced N-protein activity and the PHP-I phenotype in these families exhibited both dominant and recessive patterns of inheritance. This suggests that at least two distinct genetic loci are involved in inheritance of N-protein deficiency. In two additional families, dominant inheritance of the PHP-I phenotype was associated with normal activities of erythrocyte N protein. Thus, it appears that mutation of at least one additional genetic locus, not involving the N protein, can produce PHP-I.

Nonfunctional preaortic paraganglioma: report of one case.

A case of nonfunctional benign preaortic paraganglioma is reported. The patient, a woman aged 50, complained of vague mesogastric pain irradiated posteriorly, occasional nausea and vomiting, related to a tender pulsatile mesogastric mass fixed to the posterior wall of the abdomen. Preoperative diagnostic examinations showed a severe anemia, a severe mechanical impairment of renal function as shown at IVP, a doubt of aortic aneurism at echography, not confirmed by selective arteriography. The mass was removed radically. The diagnosis of nature was only microscopic. Since from 15 days after surgery IVP improved significantly. At three months follow-up the patient is well with no sign of recurrence.

[Mitral insufficiency associated with interatrial defect (ostium secundum). Problems of diagnosis and surgical treatment].

Of the 255 patients under observation of the AA. with ostium secundum interatrial defect who underwent surgery, 23 (9%) presented an associated mitral regurgitation. All patients had a hemodynamic test and a complete contrahistography, 8 patients polygraphic and 5 patients echocardiographic examinations. The clinical data alone, ecgraphic and Rx, supplied sufficient indications for a correct diagnosis in 87% of the cases. 22 patients underwent surgery: the septal defect was corrected in all patients, mitral regurgitation only in 9; in 5 by valve substitution, in 4 through conservative techniques. Only one patient died of cerebral coma. A report is made on the data relative to the clinical history, Rx, ecgraphic and hemodynamic examinations of the 23 patients under observation, the various anatomosurgical aspects of the valvular alterations, and the criteria adopted for the surgical correction of the mitral regurgitation.
