Abstract
We report on the main topics discussed at the "Human T-Lymphocytes in Normal and Leukemia Patients" meeting, including the "Second International Workshop on T-Cell Colonies" (Reggio Calabria, September 16-19, 1984). Improved knowledge in the field of T-lymphocyte biology has contributed greatly to a better clinical definition of T-cell-derived lymphoproliferative disorders. The T-cell colony assay seems to represent a useful tool for studying the early steps of T-lymphocyte maturation and for characterizing accessory cells and soluble mediators that regulate T-cell proliferation.

Abstract
It has been suggested that genetic predisposing factors play a role in the development of ovarian teratomas. Familial occurrence of these tumors would support this view. Reported herein are identical twins, both of whom had a right ovarian mature teratoma. In both cases the presenting symptoms were acute torsion. The diagnosis was confirmed at laparotomy and subsequent histopathologic examination. The origin of ovarian teratomas seems to be linked to the process of parthenogenesis. This process probably involves a germ cell after its first meiotic division.

Abstract
The routine in our department for years used to be: prevention of bearing down during the end of the 2nd stage of labor in high myopic parturients, by forceps delivery, with the assumption that this will prevent increased intraocular pressure--thus preventing deterioration or increased damage to the eyes. The goal of this study was to challenge our theory and thus we decided to re-evaluate this approach. Various obstetrical data were recorded in 50 women with myopia from 4.5 to 15.0 diopters who were admitted in labor to our department. Fundus examination was performed in all of them before and after delivery. Various types of retinal degeneration and retinal breaks were observed in most of them at their arrival but no deterioration of these retinal defects was observed in any of the cases at the later examination. In view of our results, it is recommended to let high myopic patients deliver spontaneously.

Abstract
Seventy-six consecutive untreated patients with B cell chronic lymphocytic leukemia (B-CLL) and classified according to Binet's staging system were studied at the clinical presentation. Several immunologic parameters (number of total and T circulating lymphocytes and their surface membrane immunoglobulin [Smlg] phenotypes and levels of serum Ig) were evaluated with the aim of identifying a biologic marker of prognostic relevance. In this series of persons, Binet staging confirmed its usefulness as a prognostic index (P less than .001). With regard to Smlg, they were mu-type in 41 cases (53.9%), mu-type plus delta-type in 29 cases (38.2%), alpha-type in one case, and not detectable in five cases. No correlations were found between clinical stage and immunoglobulin phenotype, although all but one patient in stage C showed mu-type Smlg alone. On analyzing the survival curves of our patients according to different Smlg phenotypes, we found that patients with only mu-type Smlg had a poorer prognosis (P less than .05) than those with mu-type plus delta-type; this difference was even more significant (P less than .01) in patients in stage A, whereas there were no statistical differences in those in stages B and C. Because the appearance of surface heavy chain of delta-type could be an expression of cell maturation, these results suggest that in B-CLL the presence of phenotypically more mature leukemic cells may correlate with better clinical prognosis, particularly in the early phase of the disease.

Abstract
The morphology, immunophenotype, cytoenzymatic and functional activities of T lymphocytes from 4 patients with chronic lymphoproliferative disease of T-cell origin were studied. Clonal proliferation was demonstrated by distinctive chromosomal abnormalities involving chromosomes 2 and 14. Patients 1 and 2 were classifiable as OKT4+ T-cell chronic lymphocytic leukaemia (T-CLL) and patient 3 as OKT4+/OKT8+ T-CLL, with helper function in vitro only in patient 1. Patient 4 has low-grade lymphocytosis with benign clinical course, with cells showing morphology of large granular lymphocytes (LGL), and immunophenotype HNK-1+, ER+, Fc gamma receptor+, OKT3+, OKT11+ and OKT8+, as well as natural killer activity, radiosensitive suppressor activity on Ig secretion and responsiveness to PHA; this case was interpreted as LGL leukaemia. This study indicates that a large proportion of cases of true T-CLL may belong to the OKT4 subset, and that extensive investigations should be made of the lymphocytic OKT8+/T gamma forms to characterize them precisely.

Abstract
Chorioamnionitis is a frequent cause of premature labour and delivery, as well as of maternal and neonatal mortality. Group B streptococcus (GBS) has emerged over the past decade as a common pathogen in the etiology of neonatal sepsis. The case of chorioamnionitis reported here is unusual for three reasons: the premature labour was associated with intact membrane and amniotic fluid infected with GBS; all 5 infants were contaminated with GBS and all infants survived. Chorioamniotitis with intact membranes raises some questions regarding the antepartum use of steroids (potent anti-inflammatory agents), etc. The likelihood of chorioamnionitis in spite of cervical mucus, intact membranes, and the bacteriostatic activity of the amniotic fluid should alert the obstetrician to take special precautions, such as weekly vaginal cultures and appropriate vaginal antimicrobial treatment, in cases of imminent premature delivery.

Abstract
The total and T-lymphocyte counts, different types of lymphocytic surface immunoglobulins and levels of serum immunoglobulins were studied in 112 consecutive patients with chronic lymphocytic leukemia in order to investigate possible correlations between the immunological picture and the different stages according to the staging criteria recently proposed by Binet et al. Patients were also subdivided according to the form of their disease, "indolent" or "active", and correlations with the immunological picture investigated. The total lymphocyte count showed a significantly increasing trend through the three different stage (p less than 0.01), and it was higher in the "active" than in the "indolent" disease (p less than 0.01). Also the number of T-lymphocytes increased in the "active" forms (p less than 0.01). No statistically significant correlations were observed between the different surface immunoglobulin subclasses and the clinical pattern. As regard the various classes of serum immunoglobulins, the number of patients, with a reduction of at least one of the classes tended to increase with worsening of the clinical stage.

Abstract
Natural killer (NK) cell activity against K562 cell targets and the distribution of T cell subpopulations were investigated in the peripheral blood of 25 patients affected by beta thalassemia major, 18 clinically healthy heterozygotes, and 25 age-matched normal subjects. It was found that thalassemia major patients display augmented levels of NK activity [specific lysis 41.9 +/- (se) 4.5%], while thalassemic carriers behave as normal controls [specific lysis 34.6 +/- (se) 3.5%]. The increase of NK function was neither related to the splenectomy nor to the siderosis, but rather to the age and the amount of blood units that the patients had received. An imbalance of circulating T subsets with the helper/suppressor cell ratio significantly diminished (p less than 0.001) was also detected in homozygotes but not in carriers. The finding that NK function is enhanced in homozygous beta thalassemia might be of clinical interest in assessing the risk of development of malignancies in these patients.

Abstract
The effect of epilepsy and anti-epileptic treatment on neonatal outcome was investigated in 86 pregnancies terminating in delivery. Various maternal and neonatal parameters were considered. Each infant born to an epileptic mother was double-matched with two infants born to healthy mothers and the results were submitted for statistical analysis. Infants of epileptic mothers had smaller head circumference. Primidone was the only anti-epileptic drug, taken during pregnancy, to have a significant effect on infant head circumference. The results suggest that a drug effect, rather than an association with maternal epilepsy, is responsible for this difference. Hypertelorism is the only congenital anomaly to be significantly more frequent in newborns of epileptics. All drugs, except for primidone, were associated significantly with this anomaly. Further similar studies and prolonged follow-up of the infants of epileptic mothers are necessary before drawing any final conclusions regarding the outcome of these infants.

Abstract
Rat 13762NF mammary adenocarcinoma cloned cell lines were assayed at different in vitro passage numbers and compared for their abilities to form 'spontaneous' metastases by subcutaneous injection of cells and 'experimental' metastases by intravenous injection of cells. Tumor cell clones were established from locally growing tumor and spontaneous lung metastases, and these clones were found to possess heterogeneous metastatic potentials in both metastasis assays. The rank order of clonal metastatic potentials based on either the average number of lung tumor colonies or the average total lung tumor volume was generally equivalent for 'spontaneous' and 'experimental' metastases, but some differences were noted. Ranking of 'spontaneous' metastasis by average total lung tumor volumes more closely resembled the rank order of 'experimental' metastasis than by the average number of spontaneous metastases. The results demonstrated that in the 13762NF mammary adenocarcinoma system (i) there is heterogeneity in tumor cell clonal metastatic potential using either 'spontaneous' or 'experimental' assays; (ii) these two assay methods yield generally the same rank order of metastatic potential; (iii) the metastatic potential of each of the tumor cell clones drifts with time (passage number) in cell culture, and (iv) ranking by average tumor burden calculated from total lung tumor volumes may yield a better estimate of metastatic potential than ranking by the average number of lung tumor colonies.

Abstract
Benign neutropenia is often found among healthy Yemenite Jews. An assessment was made of the magnitude of labor-induced leukocytosis in 44 Yemenite Jewish women, by comparing their hematological values during labor with those of 27 non-Yemenite women. A statistically significant difference was found in the absolute counts of the white blood cells (WBC) during delivery between the two groups, the values being lower among Yemenite Jews [10,291 +/- 422] vs. [11,759 +/- 630] X 10(9)/1) and similar findings were detected among their infants. The low WBC counts in the Yemenite group at parturition were also associated with significantly lower plasma cortisol levels (Yemenite group: 33.7 +/- 3.5 micrograms/dl; controls: 49.3 X 2.9 micrograms/dl). A correlation was found between serum cortisol levels and the magnitude of leukocytosis in both groups of women and their infants. These results suggest that a low basal corticosteroid output may contribute to the low white blood cell counts detected in some ethnic groups like the Yemenite Jews.

Abstract
The effects of various parameters on age at menopause have been investigated in five ethnic groups in Israel comprising East European, West European, North African, Israeli and other Middle Eastern (Mediterranean) women, respectively. The data were acquired by means of anonymous questionnaires and were programmed for 1770 women. Correlation coefficients between various variables and age at menopause revealed three variables which have a straight correlation, vis. obesity index, number of children, and years of amenorrhoea (during the reproductive years). The years-of-smoking variable has an inverse correlation with age at menopause. East Europeans have the highest age at menarche. Two-way analysis of variance has shown that the obesity index, years of amenorrhoea, number of children and years-of-smoking parameters are individually more important than ethnic origin. The finding that the age at menopause is highest in the North African group is explained by the higher incidence in this group of high parity, a greater number of amenorrhoea, obesity, and low cigarette consumption. Since many habits (such as smoking, diet, use of contraceptive pills, multiple partners and marital obligations) are subject to frequent change in the modern world, it is of the utmost importance to repeat such a study every few years.

Abstract
The influence of clomiphene citrate was tested in 206 women suffering from menorrhagia following the insertion of an intrauterine device (IUD). Eighty-three percent felt relief during the therapy, 10% did not benefit and 7% complained of a worsening of their symptoms. Among the women who felt an improvement, 85% responded to the 250 mg/cycle dosage, and 15% required the 350 mg/cycle dosage. Women with shortened menstrual cycles required the higher dose treatment, i.e. 350 mg, compared with women with normal cycles (36% vs. 28%, respectively). The influence of placebo was 6%. The hypothesis is raised that the mechanism of action of clomiphene citrate is the correction of the hormonal disturbances in the luteal phase of the cycle following insertion of the IUD.
