The emergency department gynaecologist and emergency postcoital contraception.

The emergency department gynaecologist is often faced with requests for emergency postcoital contraception. The physician on duty is usually very busy and does not always have enough time to perform a complete evaluation of the woman's state of health. The emergency gynaecologist who prescribes postcoital contraception also has a number of other problems to cope with in regard to the pharmacological preparations on the market, the efficacy of various methods, the monitoring of side-effects which are not, always, tolerated by all patients and the outcome of his therapeutic prescription. All these aspects should be emphasized in the "first aid" counselling offered to the patients. In conclusion, we consider that any women who decides to use postcoital contraception should have the right to receive assistance of guaranteed quality throughout the period that elapses between taking the drug and the subsequent menstrual cycle. This is not strictly guaranteed by an emergency gynaecological service.

13q14 deletion in non-Hodgkin's lymphoma: correlation with clinicopathologic features.

BACKGROUND AND OBJECTIVE: 13q14 deletion frequently occurs as a single anomaly in chronic lymphocytic leukemia (CLL) with favorable prognosis. This study was performed to assess the distribution of 13q14 deletion in non-Hodgkin's lymphoma (NHL) and to analyze its correlation with salient clinicopathologic features. DESIGN AND METHODS: One hundred and twenty-five NHL were analyzed by cytogenetics and by interphase fluorescence in situ hybridization (FISH), using a 13q14 cosmid probe recognizing DNA sequences between the Rb gene and the D13S25 marker. Clinical records all patients were surveyed. RESULTS: A 13q14 rearrangement was present in the stemline in 10 patients; 15 additional cases were shown by FISH to carry 13q14 deletion in 55-90% of the interphase cells, giving a 20% overall incidence for this anomaly. Six of 44 patients had a low-grade NHL, 14/28 had mantle cell lymphoma (MCL), 5/42 had a high grade NHL (p<0.0001). There was not correlation between 13q, karyotype status and complexity. A statistically significant association was found between 13q-, presence of splenomegaly and PB involvement, lower probability of attaining complete remission (CR) and shorter survival. These findings were not simply a function of the association of 13q- with MCL. In multivariate analysis, a complex karyotype had prognostic importance (p=0.0078), along with age (p=0.01), histology (p=0.001), LDH (p=0.03), PS (p=0.001), sex (p=0.03) and splenomegaly (p=0.02). INTERPRETATION AND CONCLUSIONS: 13q14 deletion represented an early chromosome change and showed a preferential association with MCL, though it was found in virtually all principal histologic subtypes, irrespective of clinical stage, karyotype status and complexity. Patients with 13q14 deletions had a low CR rate, suggesting that genes relevant to lymphomagenesis are located in this chromosome segment that warrants molecular cytogenetic investigation.

[The role of the gynecologist in first aid in cases of sexual violence. A protocol proposal].

The aim of this report is to provide a medical form to use in case of sexual assault, prepared taking into consideration the information lacking at present in most medical reports on the subject. This call for the necessity to conform the medical approach to the same protocol which may also be used from the forensic medicine point of view. More precise information should be obtained about the assault and the injuries inflicted, and also an immediate psychological support should be given to the victim. This information will then serve as a guide to the medical staff.

Exposure to myelotoxic agents and myelodysplasia: case-control study and correlation with clinicobiological findings.

To better define the role of exposure to myelotoxic agents in the genesis of myelodysplastic syndrome (MDS), we carried out (a) a case-control study for the determination of the relative risk (RR) of developing MDS, including 178 consecutive patients and 178 sex- and age-matched controls: (b) a study of clinicobiological features in MDS arising after occupational exposure to myelotoxic agents and in MDS in 'non-exposed' patients. The definition of the 'exposure' status was based on a predetermined questionnaire, with calculation of an 'exposure' index (hours/day x days/year x years). Cumulative exposure to pesticides or to organic solvents, for >2400 h, was recorded in 48 and 25 MDS patients, respectively, compared to 27 and four controls (P<0.00001; RR 3.74; 95% confidence interval 2.02-5.37). Older age and an excess of refractory anaemia with ringed sideroblasts and refractory anaemia with excess of blasts was noted among 'exposed' MDS-patients (group 1), compared to non-exposed MDS-patients (group 2). 68.3% patients in group 1 had clonal chromosome changes, compared with 43.2% patients in group 2. Complex karyotypes, -7/7q-, -5/5q-, +8, 7p and 17p aberrations were seen more frequently in group 1, whereas a normal karyotype, isolated 5q- or 20q- occurred more frequently in group 2. The association of exposure to myelotoxic agents with older age at presentation and with unfavourable chromosome changes accounted for the shorter survival observed in 'exposed' patients. These data show that occupational exposure to pesticides and organic solvents in our region resulted in an increased RR of developing MDS and that a distinct cytogenetic profile was associated with MDS in 'exposed' patients. These findings provide strong indirect evidence that these agents may play a role in the pathogenesis of MDS, preferentially targeting some of the chromosome regions which are frequently involved in therapy-related myeloid neoplasias.
