Alpha-heavy chain disease. Report of a case with spontaneous regression.

The occurrence of alpha-heavy chain disease in an Italian adult, working in Libya, is reported, characterized by a spontaneous clinical and immunological recovery. It is suggested that the patient could have acquired the disease during his stay in an endemic area of alpha-heavy chain disease, and that the observed spontaneous remission could be related to the removal of environmental pathogenic factors, following his departure from Libya.

Hypotensive action and side-effects of flutonidin in normal subjects. A double-blind controlled trial.

In a double blind study, planned as a 7 x 7 latin square, three oral doses of flutonidin (0.5, 1, 2 mg), of clonidine (0.0075, 0.150, 0.300 mg) and of a placebo were administered to 7 normal volunteers on 7 different treatment days, with an interval of 3 days. On each treatment day sitting blood pressure, heart rate and reaction time were measured, and sedation and dry mouth evaluated before the 1, 2, 3, 4, 6, and 8 h after administration. The placebo did not modify the basal value of any variable. Flutonidin and clonidine produced dose-related effects on blood pressure, heart rate, sedation and dry mouth, but did not influence reaction time. Analysis of the dose-response curves demonstrated that the effect of flutonidin was one-fifth to one-twelfth that of clonidine, depending on which variable was considered.

Human platelet aggregation curve and oral contraception.

In a series of in vitro experiments, the authors investigated the different aspects of the aggregation curves of human blood platelets taken from a group of women who received oral contraceptives, another group of women who did not receive oral contraceptives and a group of men. The platelets were subjected to ADP stimulation. The authors showed that at the lower doses (0.44 and 0.88 . 10(-6) M) of ADP the aggregation and the disaggregation of the platelets from the women who received oral contraceptives was significantly greater than that of the two other groups. The authors proposed that these may be due to an increase of the sensitivity of the platelets to the aggregating stimuli in that group of women who were under oral contraception.

[Clinical study of a new preparation in the treatment of anorectal varices].

Sterectal is a new antihemorrhoidal drug which contains prednacinolone, lidocaine hidrochloride and ephedrine hidrochloride. The results of the double blind, between patient, clinical study carried out in order to detect effectiveness of Sterectal compared with placebo show that the new drug owns a more rapid onset of therapeutic activity and exhibits a greater reduction in symptom severity than placebo. Both treatments were well tolerated.

Experimental evaluation in man of analgesic effects.

A device operated by compression has been studied in order to define a method of measuring analgesic effects. Three analgesics (metamizol, acetylsalicylic acid and ketobemidone) and placebo have been tested in man to verify the adequacy of this apparatus and its sensitivity.

Causes of death and postsurgical survival in familial adenomatous polyposis: results from the Italian Registry. Italian Registry of Familial Polyposis Writing Committee.

Causes of death were evaluated among 350 deceased patients with familial adenomatous polyposis (FAP) recorded in the Italian Polyposis Registry: 78.1% were due to colorectal cancer, 9.5% to extracolonic cancer (more than half of the upper gastrointestinal tract), 3.6% to desmoid tumors, and 8.8% to other causes. The age at diagnosis among 604 patients was studied in relation to presence of symptoms at presentation and presence of colonic cancer at surgery. In asymptomatic patients younger than 30 years the risk of colonic cancer was 3.3% and in symptomatic patients older than 40 it was 80%. A life-table analysis showed that postsurgical survival among patients without cancer at colectomy was 68% after 30 years, whereas that of patients with cancer was 41% after 10 years. The alternative prophylactic treatments of total colectomy with ileorectal anastomosis versus total proctocolectomy (IRA vs. IAA) were compared in terms of postsurgical survival. Both treatments showed a survival of 83% after 10 years. The risk of cancer in the rectal stump after IRA was 14.5% after 15 years and 25.2% after 25 years; the corresponding risks of dying from it were 4.3% and 9.3%, respectively.

Phenotypic characterization of immunomagnetically purified umbilical cord blood CD34+ cells.

This study describes the multilineage differentiation pattern of purified CD34+ stem cells obtained from human umbilical cord blood. CD34+ cells were collected from 49 umbilical cord blood samples. Following immunomagnetic purification, cells were double stained with anti CD34 and CD71, CD61, CD7, CD19, CD33, CD36 and triple stained with anti CD34, CD38 and HLA-DR. Analysis were performed using a FACScan flow cytometer. After purification, the mean CD34+ cells' purity was 85.49 +/- 7.08%. Several subpopulations of umbilical cord blood CD34+ cells were identified indicating different lineage commitment. The majority of CD34+ cells expressed both CD38 and HLA-DR (91.74 +/- 3.76%), while those lacking CD38 were 3.43 +/- 2.12% (CD38-DR+) and 1.81 +/- 1.54% (CD38-DR-). These data were compared to the expression of lineage commitment markers on purified CD34+ cells from 5 mobilized peripheral blood samples. The percentage of peripheral blood CD34+CD38-DR+) and CD34+CD38-DR- cells was significantly lower than umbilical cord blood, 0.24 +/- 0.18% and 0.04 +/- 0.03% respectively. The knowledge and standardized of umbilical cord blood CD34+ cells phenotype is critical since umbilical cord blood volume is limited. The homogeneity of CD34+ subpopulation phenotype suggests that monitoring of lineage differentiation antigens may not be relevant for clinical use of umbilical cord blood samples. However, the observed higher percentage of pluripotent CD34+38- stem cells in umbilical cord blood compared to peripheral blood, that might explain the successful clinical use of umbilical cord blood even when low number of cells are used, candidates these antigens as the predictive parameter for clinical use of umbilical cord blood samples.
