Abstract
BACKGROUND The aim of the present study was to compare cranial arteries blood flow velocity as measured by means of transcranial Doppler sonography (TCD) with mean regional cerebral blood flow (rCBF) as measured by means of single photon emission computed tomography (SPECT) in migraine with and without aura during headache-free periods and spontaneous and/or induced attacks. METHODS Regional cerebral blood flow (rCBF) and systematic ultrasonic Doppler flow were studied by Technetium-99m hexamethylpropilaminoxime (99mTc-HM-PAO) single photon emission computed tomography (SPECT) and transcranial Doppler sonography (TCD) respectively in controls (n=14) and in migraine with (n=13) and without aura (n=35) during headache free-intervals and spontaneous/histamine-induced attacks. RESULTS In the migraine without aura group, Doppler flow examinations of the common carotid artery, external and internal carotid artery, ophthalmic artery and middle cerebral artery bilaterally did not reveal significant changes as compared with controls. During attacks, TCD examinations showed a moderate, although not statistically significant, reduction of blood flow velocity in the middle cerebral artery and in the internal carotid artery bilaterally as related to the interictal phase, concomitant with an increase of the flow velocity in the ophthalmic and external carotid artery. SPECT of these patients did not show, on the average, rCBF asymmetries during pain-free periods, although positive findings (i.e., focal hypoperfusion) were found in approximately half of the cases. During attacks, 74% of patients displayed a unilateral hypoperfusion, mainly in the occipital region. Low-flow areas were generally but not always consistent with the site of pain. In the migraine with aura group, significant reduction of blood flow velocity in middle cerebral artery was recorded by TCD on the affected side during attacks, as compared with the pain-free side. Hypoperfusion was registered between attacks by SPECT in approximately 2/3 of the patients. During attacks, a marked reduction of rCBF occurred in most patients (85%), mainly in the parieto-occipital region. The posterior rCBF asymmetries revealed at the SPECT and consistent with the general reduction of blood flow velocity documented by TCD may be related to cerebrovascular tone instability. CONCLUSIONS Our findings do not support the paradigm that migraine with and without aura are two different entities.

Abstract
Multimodality evoked potentials (somatosensory and acoustic) have been recorded before surgery in children selected for surgical treatment for different kinds of craniostenosis and craniofacial stenosis. Evoked potentials were found to be deranged on at least one recording in 50% of cases, suggesting a significant incidence of neurophysiological alterations in these patients. No correlation was found between evoked potentials' derangements and clinical status, radiological findings, or different kinds of craniostenosis; moreover, a significant correlation was found between neurophysiological alterations and the age of the children. These preliminary data might define the possible role of neurophysiological tests in the presurgical evaluation of craniostenosis and craniofacial stenosis.

Abstract
We treated a 6-year-old child for hyperteleorbitism. We performed a facial bipartition steel wire osteosynthesis of the frontal bone. After 7 years we observed two episodes of pneumococcal meningitis, which were treated with intravenous antibiotic, resulting in a prompt recovery. The computed tomographic scan and nuclear magnetic resonance image showed the steel wire included in the frontal sinus and in contact with the dura mater. Removal of the wire and suture of the dura allowed prompt recovery.

Abstract
Inhalation anesthetics diminish cerebrovascular resistance, augmenting cerebral blood flow (CBF) and hematic volume. This may lead to a dangerous increase in intracranial pressure (ICP). It has been observed that isoflurane used in hypocapnia does not appear to cause an increase in ICP equal to that caused by other inhalation anesthetics. The authors aimed to evaluate the effects of isoflurane on ICP and on intracranial vessel reactivity to changes in CO2 using a pulsed intracranial Doppler technique which measures cerebral flow velocity (CFV). A prospective study was performed at the Neurosurgery Clinic of the University of Milan in 10 in-patients due to undergo surgical removal of supratentorial intracranial expansion. Patients were anesthetised with isoflurane 1 MAC in air and O2. The following parameters were monitored: ICP at a spinal subarachnoid level; mean arterial pressure (MAP); cerebral perfusion pressure (CPP); ECG; CFV; EtCO2. The study was subdivided into 5 stages: basal (before induction); hypocapnia lasting 30 min; registration of data for 10 min; stabilisation phase in normocapnia; registration in normocapnia. The results show that during hypocapnia isoflurane causes significant reductions in MAP and CCP whereas ICP and CFV tend to diminish but not significantly. On the contrary, isoflurane in normocapnia causes an increase in ICP and a further and more marked reduction in CPP with a corresponding but not significant increase in CFV. In conclusion, in the light of these results the increase in ICP and the contemporary reduction of MAP would appear to restrict the use of isoflurane in normocapnia in patients with intracranial pathologies.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We report the results of a molecular investigation of 11 patients affected by Waldenström's macroglobulinemia, a rare B-cell malignancy characterized by an excessive proliferation of immunoglobulin (Ig)M-secreting plasmacytoid cells. In particular, we studied the interleukin-4 (IL4) gene, which codes for a B-specific growth factor capable of stimulating the proliferation and differentiation of secreting plasma cells. By Southern hybridization, in three patients we found the presence of additional bands in comparison with the expected pattern; moreover, these bands showed a different degree of intensity.

Abstract
The association between breast feeding and acute lower respiratory infection (ALRI) was studied in a case-control study in southern Italy. Two groups of children were studied: the first group comprised 73 infants, aged 0-6 months, whose diagnosis was pneumonia or bronchiolitis; the second group included 88 infants less than 12 months of age with a diagnosis of pertussis-like illness. Control infants were two groups of infants admitted to the same ward. Compared with controls, infants in the first group were less likely to have been breast fed (odds ratio 0.42, 95% CI 0.19-0.90). The protection conferred by breast feeding was stronger among infants who were receiving human milk at the time of admission (odds ratio 0.22, 95% CI 0.09-0.55) and was absent among those infants who had stopped breast feeding for two or more weeks before admission. Among infants who were severely ill, breast feeding was less likely than among those with milder illnesses. There was evidence in the stratified analysis of effect modification by the presence of other children in the family. Among the infants with pertussis-like illness, the incidence and duration of breast feeding were not different compared with controls. The results suggest that breast feeding has a strong protective effect against ALRI in industrialized countries also. No protection seems to be conferred by human milk against pertussis-like illness.

Abstract
Results on sister chromatid exchange (SCE) frequency and interchromosomal distribution in bone marrow and peripheral blood cultures from patients with Waldenström's macroglobulinemia are reported. PHA-stimulated bone marrow cultures showed increased SCE frequencies in all 12 patients examined. The increase was particularly high in two cases (17.07 and 16.77 SCE/cell, respectively) and, in one of them, a very high SCE level was found in PHA-stimulated peripheral blood culture (40.81 SCE/cell). In LPS-stimulated cultures, increased SCE levels were observed in some patients. Comparison between SCE frequency in bone marrow cell cultures with either mitogen showed a significant increase in PHA-stimulated cultures. Analysis of the interchromosomal SCE distribution revealed significant differences with respect to the control values; however, these differences were variable in the different patients. In pooled data of PHA-stimulated bone marrow cultures, there were differences between expected and observed SCEs in chromosomes 1 and 2 and in B, E, F, and G chromosome groups. Results of cell cycle modifications are also reported.

Abstract
We report the results of cytogenetic studies of direct bone marrow (BM) preparations and of short-term BM and peripheral blood (PB) cultures from 17 patients with Waldenström's macroglobulinemia. We noted clonal chromosome changes in 10 patients. Abnormalities affected chromosomes X, Y, 2, 4, 5, 15, 16, 18, 19, 20, 21, and 22; in particular, chromosomes 2, 4, and 5 were involved in structural changes: a homogeneously staining region [hsr(2)], a der(4)t(4;?)(q32;?), and a 5q+. The other chromosomes were involved in numerical abnormalities, such as pseudodiploidy (a 46,X, -X, + 15 clone), loss of chromosome Y, and monosomy of chromosomes 16, 18, 19, 20, 21, and 22. Nonclonal chromosome rearrangements were also observed. The results are discussed in comparison with the few data reported in the literature, and the finding of an hsr in the long arm of chromosome 2 is emphasized; indeed, this is the first report of hsr in WM.

Abstract
We have report the results of cytogenetic studies carried out in eight patients with acute nonlymphocytic leukemia developed after primary neoplasias. In seven of the reported cases, clonal chromosome aberrations were found, some being specific of de novo acute nonlymphocytic leukemia (ANLL). Numerical abnormalities were detected, such as the total monosomy of chromosomes 5, 7, 21, trisomy of chromosomes 8, 11, 15, and duplication of chromosome Y. Structural changes were also observed: a del(12)(p12), a del(16)(q22), the translocations t(3;5)(p21;q35),t(3;7)(p21;q35), and t(12;14)(p12;q32) and other changes involving chromosome 8. The finding of a hypertetraploid karyotype with complex structural chromosome aberrations in a patient with erythroleukemia, developed after non-Hodgkin's lymphoma, is of particular interest. Data reported in this work are discussed with regard to the relationship between secondary and de novo ANLL and the finding of chromosome aberrations other than total or partial monosomy of chromosomes 5 and 7 is emphasized.

Abstract
We developed two different models based on in vitro co-culture of hormone-dependent and hormone-independent cell lines to simulate the cell population heterogeneity of human breast cancer tumours. Oestrogen-dependent (MCF-7, ZR 75.1) and oestrogen-independent cell lines (MDAMB-231 BT-20) were grown under serum-free conditions. Co-culture of hormone-dependent and hormone-independent cell lines resulted in an increased cell yield compared to single cell cultures carried out at the same seeding ratios. Such an increase was not affected by addition of oestradiol and single growth factors (EGF, bFGF and IGF-I). These results allow us to conclude that in a heterogeneous cell population like human breast tumours, interaction between hormone-dependent and hormone-independent cell lines may result in a complex regulation of cell growth.

Abstract
We utilized, in CHO cells, the cytoplasm preservation technique to evaluate the micronucleus frequency at different busulphan concentrations, and the indirect immunofluorescence technique, using sera obtained from patients with scleroderma (CREST variant), to analyze if busulphan-induced micronuclei have kinetochores. Results show that this alkylating agent is capable of causing a significant increase of micronuclei in vitro, a great part (40%) of them having CREST-positive kinetochores. These findings confirm the clastogenic effect of busulphan and reveal a considerable capability of this agent to induce aneuploidy. These results are examined taking into account the high incidence of secondary neoplasias induced by chemotherapy with alkylating agents utilized against primary neoplasias.

Abstract
The concentration of total cathepsin D in cytosols of 199 node negative women with primary breast cancer in a 10-year retrospective cohort was assayed. Cathepsin D status alone was unable to predict disease-free or overall survival. However, those patients with receptor positive tumours who were cathepsin D positive had shorter [corrected] disease-free (P = 0.02) and overall survival (P = 0.01) than cathepsin D negative patients. Therefore, measurement of cathepsin D appears to provide additional prognostic information for the prediction of disease-free and overall survival in patients with node negative breast cancer.

Abstract
To better understand the mechanism of action of antiestrogens, the growth-inhibitory effect of tamoxifen and its main metabolites N-desmethyltamoxifen and 4-hydroxytamoxifen, was studied in 6 breast cancer cell lines characterized by different steroid receptor contents. On the basis of the results, our cell lines could be classified into three groups: a first group, including 734B and ZR-75.1 cell lines, characterized by a clear endocrine-dependent behavior, in which cells were sensitive to antiestrogens although to different degrees; a second group, including MDA-MB 231 and BT20 cell lines, characterized by a clear endocrine-insensitive behavior, in which cells were affected only by the highest (10(-6) M) antiestrogen concentration; a third group, including MCF7 and T47D cell lines, characterized by a peculiar behavior. The T47D cell line displayed an increased growth rate after treatment with all three antiestrogens considered. Despite the positive receptor content in the MCF7 cell line, only 4-hydroxytamoxifen showed a clear antiestrogen dose-dependent effect, whereas tamoxifen decreased the cell growth rate only at lower concentrations (10(-8) and 10(-7) M). These results and the well-known heterogeneity of human breast tumors explain the failure of antiestrogen treatment in a certain percentage of patients with breast cancer with a positive estrogen receptor status.

Abstract
Laboratory data from Milan and Houston were evaluated to determine the extent to which the distribution of estrogen receptor (ER) and progesterone receptor (PgR) has changed with time. Results from over 11,500 ER and over 8,200 PgR determinations (6,194 ER and 3,127 PgR from Milan) were analyzed. All assays in Milan were performed by a dextran-coated charcoal method and in Houston by a sucrose density-gradient method. The data demonstrate a time-dependent, upward drift in the amount of ER and PgR detected, with the effect most pronounced at the lower end of the distribution curves. We attribute this change to optimization of all facets of the receptor assay procedures (tissue harvesting and storage) as well as to a change in breast cancer biology. These results suggest that studies correlating certain biological parameters with receptor status (whether using qualitative or quantitative scales) need to be re-examined. For example, a population of 349 node-negative patients who did not receive any adjuvant treatment was studied in Milan to determine any association between disease-free survival (DFS) and receptor status. If the "historical" threshold values (10 fmol/mg protein) were used to determine receptor status, no significant difference in DFS at 5 years was detected. Even the combination of ER and PgR did not improve the predictive power of receptor status. In the premenopausal subgroup, ER status did predict the 5-year DFS. However, if the threshold value for PgR was adjusted to 25 fmol/mg protein, patients with ER-positive, PgR-positive tumors had significantly better 5-year DFS than patients with ER-negative, PgR-negative tumors. In addition, PgR status alone was associated with significantly improved 3-year DFS if the subgroups of PgR less than 5 fmol/mg protein and PgR greater than 100 fmol/mg protein were compared. We conclude from these data that: 1) historical threshold values for receptor positivity should be re-examined in all laboratories; 2) studies involving receptor results determined over an extended period of time should attempt to "normalize" these results; and 3) the quantitative assessment of receptor status should be used whenever possible.

Abstract
17 beta-Estradiol is a potent mitogen for hormone-dependent cell lines (MCF-7, T47D and ZR 75.1). However, the degree of hormone sensitivity is very much influenced by culture conditions. In order to understand which factors modulate estrogenic effects on cell growth, four different culture conditions were used: (a) medium with dextran-coated charcoal-treated fetal calf serum (DCC-FCS); (b) medium with dextran-coated charcoal-treated growth factor-inactivated serum (DCC-FCSd); (c) serum-free medium, after a 24-h incubation with serum to allow cell attachment; and (d) serum-free medium on collagen IV-treated plates. In all cell lines the highest cell growth stimulation was achieved when estradiol was added in the presence of 5% DCC-FCS, whereas reducing or removing serum from the culture medium resulted in a decrease in cell proliferation stimulation. We postulate that serum contains some still unknown components able to modulate the degree of estrogenic action in endocrine-dependent breast cancer cell lines.

Progesterone receptors were determined on frozen sections from 74 primary human breast tumors by an immunocytochemical assay using an indirect avidin-biotin peroxidase method. In the same tumors, cytosol estrogen (ERc) and progesterone receptors (PgRc) were determined by ligand binding assay, and nuclear estrogen (ERn) and progesterone receptors (PgRn) were determined by an immunoassay. Immunocytochemical staining was seen in 36% of tumors. It was predominantly nuclear and there was extensive cell to cell heterogeneity. When the immunocytochemical results were compared to PgRc the agreement rate was 63%, but it was 77% when compared to PgRn. About one third (38%) of PgRc positive tumors were immunocytochemically defined as negative. Thus a significant discordance exists between this immunocytochemical assay for PgR and both the conventional radioligand assay (used for PgRc) and the relatively new enzyme immunoassay (used for PgRn). However discordance rates were critically influenced by the arbitrary cutoff levels that were used to define receptor positivity in the biochemical assays. Our studies support the addition to, rather than the substitution of, immunocytochemical methods, to the conventional biochemical assays for PgR, until long-term follow-up studies of patients with PgRn and immunocytochemical PgR determinations become available.

Abstract
The effects of propofol on cerebral blood flow velocity, cerebrospinal fluid pressure, cerebral perfusion pressure and mean arterial pressure were studied during induction in 25 patients scheduled for elective craniotomy. Premedication consisted of only atropine sulphate 0.007 mg/kg (im) 45 min before induction. Measurements were made or derived at time zero and 1, 2, 3, 4 and 5 min after an induction dose of propofol (2.5 mg/kg). Patients were retrospectively stratified into two groups, according to cerebrospinal pressure basal values: (i) lower than 10 mmHg (10 pts) and (ii) higher than 10 mmHg (15 pts). Cerebral blood flow velocity, measured by transcranial Doppler, fell in all the patients, but the reduction was significant at 1, 2, 3 and 4 min only in the group with high CSF pressure, while it never reached the critical value of 10 cm/s. Cerebrospinal fluid pressure and mean arterial pressure decreased in both groups of patients and the fall reached a statistical significance at 1 and 2 min in the group with higher baseline CSF pressure, only at 1 min: a parallel decrease of CPP was recorded, but it was not significant. Thus propofol decreases CSF pressure without hazardous effects on cerebral blood velocity and on cerebral perfusion pressure and seems to be a suitable anaesthetic agent in controlling high cerebrospinal fluid pressure in neuroanaesthesia.

Abstract
Results following percutaneous thermorhizotomy for trigeminal neuralgia are described in 111 patients. Recurrences and side effects are more frequent whenever selectivity of the surgical lesion has been imperfect (exceeding the original pain area and causing marked hypoesthesia), and less frequent in the cases with strictly selective lesion.

Abstract
Simultaneous involvement of bands 8p11 and 16p13 in a primary, even though rare, chromosomal translocation recently described in acute nonlymphocytic leukemia may be of crucial interest in some subtypes of this acute leukemia, particularly in the monocytic form. In the present report we describe this translocation in acute nonlymphoblastic leukemia FAB M4, possibly secondary to Hodgkin's disease, though it is also possible that the leukemia may have developed de novo. The aberration t(8;16)(p11;p13) was present in 100% of direct and cultured bone marrow cell preparations. A very high frequency of cells with nonclonal structural chromosome aberrations was also observed in peripheral blood cultures (more than 53%). Random translocations and deletions constituted most of the observed alterations. These findings are discussed with regard to the relationships between secondary leukemias and intensive polychemotherapeutic treatments of primary neoplasias.

Abstract
Steroid receptors were measured in a series of 30 operable canine mammary gland tumors; both cytoplasmic estrogen (ERc) and progesterone (PgRc) receptor mean concentrations were very low with respect to the mean levels found in humans. Therefore a study was designed to modulate receptor levels by administration of Tamoxifen and Etretinate, either alone or in combination. Forty dogs with resectable, histologically documented mammary gland tumors were subdivided into the following treatment groups: a. Etretinate (1 mg/kg/d) p.o. for 7 days followed by Tamoxifen (0.7 mg/kg/d) p.o. for 7 days; b. Tamoxifen (0.7 mg/kg/d) p.o. for 14 days; c. Etretinate (1 mg/kg/d) p.o. for 14 days; d. 14 days placebo, and cytoplasmic ERc and PgRc and nuclear ER (ERn) were measured before and after the treatment. An increase of ERc and ERn was observed after administration of Tamoxifen, while an increase of ERc only was seen after treatment with Etretinate. We conclude that canine mammary tumors are indeed hormone sensitive despite their very low receptor concentrations and a suitable treatment can in fact modulate receptor levels. However, further studies are needed better to define the optimal treatment regimen in order to achieve maximal steroid receptor induction.

Abstract
Clonal chromosome changes were found in a patient with FAB-L1 acute lymphoblastic leukemia. The changes consisted of a t(8;14)(q24;q32), Burkitt type, and a rare marker chromosome 1p-. The breakpoint in this chromosome was localized at band 1p22. Both these abnormalities were present in 100% of unstimulated peripheral blood cells. The detection of the t(8;14) in a case of acute lymphoblastic leukemia, without a clear evidence of B immunophenotype and with an unusual long survival (more than 3 years), is discussed.

Abstract
Human breast cancer cell lines, as well as human breast cancer biopsies, possess specific high-affinity epidermal growth factor receptors (EGF-r). However, reports on the presence of EGF-r in human breast cancer biopsies are still controversial, especially concerning the relationship between EGF-r and other biological variables whose prognostic relevance is well known, such as the estrogen (ER) and progesterone (PgR) receptors. In the present study, the EGF-r content was estimated in a series of 136 unselected breast cancer primaries along with cytoplasmic (ERc) and nuclear (ERn) ER and cytoplasmic PgR. EGF-binding activity consisted of a single class of high-affinity binding sites (Kd = 0.55 nM) and ranged from 0 to 275 fmol/mg protein. We observed a strong inverse association between EGF-r and ERc (p less than 0.001); in fact, about two thirds of the tumors were ERc-positive/EGF-r-negative or ERc-negative/EGF-r-positive. The same type of association was found between EGF-r and either ERn or PgR. Kendall's rank correlation test confirmed that the EGF-r concentrations were correlated with the levels of ERc (tau = -0.291, p less than 0.0001), ERn (tau = -0.27, p less than 0.0005) and PgR (tau = -0.162, p less than 0.01). The EGF-r content was significantly higher (p less than 0.0001) in the ERc-negative tumors (72.6 +/- 54.4 fmol/mg protein) as compared to the ERc-positive ones (33.0 +/- 37.4 fmol/mg protein). Similarly, the subset of PgR-positive tumors was characterized by lower EGF-r mean concentrations when compared to PgR-negative cases (35.4 +/- 54.4 vs. 63.8 +/- 54.4 fmol/mg protein). These results confirm the previously described inverse relationship between EGF-r and steroid receptors. Moreover, they suggest the existence of an interaction between steroid hormones and EGF and support the need for further studies to better understand their respective roles in modulating breast cancer growth.

Abstract
Several karyotype changes observed during the blastic phase in 2 patients with Philadelphia chromosome (Ph)-positive chronic myeloid leukemia (CML) are reported. Rearrangements involving chromosome 1, i.e., translocations, a pericentric inversion and trisomies of its long arm, are described. In the first patient whose chronic phase was very long (17 years), the uncommon association between i(17q) and Ph duplication has been observed during the blastic phase, beside the involvement of chromosome 1. In the second patient, additional abnormalities involving chromosomes 1, 2, 4, 8, 18 and 21 were present. Of particular interest is the finding of a t(1;2). In this case, the presence of hyperdiploid cells with 49-50 chromosomes, prevailing at the blastic crisis, was due to the evolution of the hypodiploid clone with the 45,XX,t(9;22),-21 karyotype found during the chronic phase. The occurrence of chromosomal changes involving chromosome 1 during the blastic phase of CML is emphasized.

Abstract
We have compared a new enzyme immunoassay (EIA) for estrogen receptors (ER) with our conventional radioligand binding assays (multipoint dextran-coated charcoal assay for cytoplasmic ER and hydroxylapatite exchange assay for nuclear ER). Cytoplasmic ERs were measured in 76 human breast cancer specimens by EIA and by five-point Scatchard analysis. The correlation between the two assays yielded a straight line with a slope of 0.92 (r = 0.95; P less than 0.001); conversely, in 31 nuclear salt extracts, linear regression analysis of hydroxylapatite exchange assay data with EIA showed a clear correlation (r = 0.93; P less than 0.001) but a slope of 1.7, demonstrating that EIA detects more ER sites. The binding of the antibody to the cytoplasmic ER molecules was investigated by sucrose density gradient analysis, which showed that EIA recognizes both cytoplasmic forms (9 and 3S), but does not distinguish between them. Advantages and drawbacks of this method are discussed with respect to its application for routine receptor determination for clinical management of breast cancer patients.

Abstract
We report a complex rearrangement observed in both the short and long arms of chromosome #3 in a patient with Ph-positive chronic myeloid leukemia in blastic crisis and without thrombopoietic abnormalities. The rearrangement consisted of a complex translocation, t(3;9;22)(p21;q34;q11), and a paracentric inversion of the long arm of the same chromosome #3 involved in the translocation. Involvement of chromosome #3 in complex translocations in chronic myeloid leukemia and the relationship between 3q anomalies and thrombopoietic diseases are discussed.

Abstract
Cytogenetic findings obtained during the clinical course in two patients (one child and one adult) with Ph-positive acute lymphoblastic leukemia (ALL) are reported. Chromosomal abnormalities in addition to Ph chromosome were detected in both patients. At the beginning of the disease, such abnormalities consisted of the trisomy of chromosome 1 and monosomy of chromosomes 8 and 9, with a sub-line 45, XY, Ph, -8 in the child; in the adult patient a hyperdiploid clone with 57-59 chromosomes and Ph duplication was present. At relapse, the same karyotypic anomalies reappeared in the child, whereas in the adult a high frequency of chromosomal rearrangements, such as ring and dicentric chromosomes, was observed after cranial irradiation. The occurrence of chromosomal abnormalities additional to Ph during the clinical course in ALL patients is discussed, taking into account data from the literature concerning the lymphoid blastic crisis in chronic myeloid leukemia patients.

Abstract
Cytogenetic studies in peripheral blood and bone marrow cells from a female patient (aged 31 years) with inherited aplastic anemia and without other congenital anomalies are reported. Endoreduplication was increased in stimulated peripheral lymphocytes in several investigations. Chromosome breaks were shown to be near the control frequency, although chromatid exchange figures and dicentrics were present. Cytogenetic analysis was extended to the three children of our patient. Abnormal clones were detected in bone marrow preparations of our patient in all cytogenetic investigations. At the first examination, two of these clones were prevalent, with their karyotypes being 48,XX, +9, +16 and 46,XX,dup(1)(q24----q32),t(17;?)(p12-13;?). The prevailing karyotype after 2 years was 46,XX,t(17;?)(p12-13;?). Involvement of chromosomes #1 and #17 is discussed, taking into account data from the literature concerning several human neoplasias.

Abstract
Chromosome studies of five patients with myelofibrosis and myeloid metaplasia were carried out on bone marrow cells and/or on peripheral blood without PHA. Abnormal clones were found in three patients. Such clones were a minority, compared with the number of cells with normal karyotypes in all three patients. Chromosomes abnormalities consisted of 5q- (case 5), 13q- (case 2), and a small supernumerary acrocentric marker (case 3). One of our five patients, a woman aged 75 (case 1), showed a constitutional karyotype 46,XX,inv(5)( p15q11 ). The same chromosome rearrangement was present in 100% of the stimulated peripheral lymphocytes of this patient and in one of her sons with a normal phenotype. One patient (case 4) had a normal karyotype. These results are discussed and compared with data from the literature concerning myelofibrosis and other myeloproliferative diseases.

Abstract
Intraventricular hemorrhage (IVH) is usually the result of life-threatening intracranial bleedings eventually leading to death. Early ventricular drainage is suggested as a possible means of reducing fatalities. The retrospective analysis of 80 patients with CT diagnosed IVHs has indeed shown that early drainage prolongs significantly survival before death but does not influence mortality. Clinical and CT grading still remain fundamental prognostic indexes accounting for the irreversible hemorrhagic lesion. Thus ICP monitoring and ventricular drainage may be useful only in selected patients with alterations of consciousness of intermediate severity and sluggish evolution.

Abstract
In direct preparations of bone marrow cells from an 18 years old patient with Fanconi's anaemia (FA) a low frequency of structural chromosome aberrations was observed (4% excluding gaps), while in cultured bone marrow cells (48 hours) and in cultured peripheral lymphocytes such aberrations were found to be about 3 times as many. The increase of chromosome abnormalities "in vitro" is discussed and the most recent observations on possible factors determining susceptibility to chromosome breakage in cases with FA are taken into account.

Abstract
Thirty-six patients with SAH were submitted to continuous ICP monitoring: in 33 cases a continuous ventricular fluid pressure recording was performed in acute stage. According to Hunt and Hess, 2 patients were graded I, one II, one III, 13 IV and 16 V. In the remaining 3 cases who developed a normal pressure hydrocephalus 15, 20 and 40 days from bleeding an extradural miniaturized transducer was applied. B and C waves were common findings in acutely recorded patients. Typical A waves accompanied base line recordings in patients with NPH. From analysis of data the authors evidenced that elevated ICP values have been registered not only in patients graded as III, IV and V but also in those graded I and II: as 89% of patients belong to grades IV and V it was impossible to correlate clinical status with ICP. In patients with spasm it was never noted ICP values higher than 20 mmHg during recording time (from 60 hours to 10 days). In order to reduce intracranial hypertension CSF drainage was performed in 33 patients acutely registered. In patients graded I and II this procedure was followed by an ICP reduction and an improvement of the clinical status. In none of the patients graded IV and V in spite of pressure maintained at 10 mmHg, CSF drainage affected clinical evolution.

Statistical analysis (chi2 test) of the interchromosomal distribution of sister chromatid exchanges in bone marrow cells from 3 patients with refractory anemia showed significant differences concerning chromosome 1. Analysis of intrachromosomal sister chromatid exchange distribution concerning chromosome 1 showed that a considerable number of sister chromatid exchanges is localized in the terminal segments of both chromosome arms.

Abstract
In a series of 2.980 brain-injured patients, 84 (2.8%) showed epileptic seizures. Epilepsy occurred with a higher incidence rate in operated patients (11.6%) than in non operated ones (1.2%). Seizures appeared within the first week since trauma in 91% of the cases. They have been single in 48%, recurring in 34%, with figures of status epilepticus in 16% partial in 61%, and GM in 33%. Prognosis quoad vitam of early epilepsy seems to be favourable, however, in severely brain-injured patients, seizures occur more frequently and may determine a worsening of the clinical picture even if they are not responsible for the death.
