[Value of endocervical margin examination of conization specimens. Prospective study conducted on 150 patients].
OBJECTIVE: To assess the usefulness of frozen sections (FS) on endocervical margin in surgical conization or loop electrosurgical specimens. MATERIAL AND METHODS: In a prospective study, 150 patients were treated from October 1995 to December 1997: 69 cases without FS, 81 cases with FS. CIN on frozen section resulted in an immediate additional resection. RESULTS: In the group without FS, 13 patients had involved endocervical margin by high-grade CIN (18.8%). Frozen section was impossible in a conization specimen that was too short. FS revealed 64 normal glandular epitheliums, seven squamous metaplasias in which two lesions were under-evaluated (being in fact CIN on permanent sections), eight high-grade CIN followed by additional resection in six cases and two invasive carcinomas. Endocervical margin on additionals section were always free of disease. The rate of failure was 2.6% among 77 cases. This rate corresponded to two under-evaluations. Invasive carcinoma and CIN without additional resection were excluded because frozen section only allowed a peroperative diagnosis. The average height of the cone and the rate of complications were similar. Repeat surgery was necessary in nine cases in the group without frozen section, in which five showed residual lesions, absent in the other group. CONCLUSION: The ultimate histological interpretation was never difficult after frozen section. This method permits reduction of cases with involved cone margin and residual lesions and, despite some limitations, it may be useful for surgical management.

Cytologic differential diagnosis of bronchiolo-alveolar carcinoma and bronchogenic adenocarcinoma.
In order to estimate the possibility of a cytologic differential diagnosis of bronchiolo-alveolar carcinoma and bronchogenic adenocarcinoma, 121 histologically proven cases of these two types of lung cancer were studied. Certain features of the tumor cells were used as differential diagnostic parameters. By means of these features it was possible to correctly type 90% of the bronchiolo-alveolar carcinomas and 72% of the bronchogenic adenocarcinomas. The most striking characteristics of bronchiolo-alveolar carcinoma was the uniformity of cells, the occurrence of such cells in tightly packed clusters, the absence of prominent nucleoli and also the scarcity of single tumor cells. Thus, it seems possible to make a correct cytologic differential diagnosis between these two types of lung tumors with high accuracy.

[Identification and treatment of endometritis].
Endometritis represent a debatable entity because genital infectious disease is a contre-indication of endoscopy. So, the diagnosis is rarely realized by hysteroscopy. Two kinds of endometritis are discerned: acute endometritis characterized by an oedema of bleeding endometrium, covered by an abnormal mucus; chronic endometritis with areas of red endometrium, flushed, with a white central point, localized or scattered out the cavity. This is the "strawberry aspect". Whereas, the correlation between hysteroscopic aspect and histologic or bacteriologic samples exists in only 35% of cases. According to R. Frydman and J. Hamou, chronic endometritis is occurred among 22% of patients in IVF program, in 14% of unexplained infertility and 23.6% of women with an history of first trimester miscarriages. Chlamydiae an Ureaplasma seem to be the most frequent germs. In this way, in case of unexplained infertility, the hysteroscopic diagnosis of chronic endometritis can lead to an antibiotic treatment test.

[Hysteroscopic surgery and fertility].
In the treatment of uterine lesions associated with infertility, such as septate uterus and synechiae, hysteroscopic surgery has replaced conventional abdominal surgery. Hysteroscopic metroplasty improves obstetrical prognosis in patients with septate uterus. Advantages of hysteroscopy are low morbidity rate, decreased hospitalization time, and absence of hysterotomy. Hysteroscopic surgery of synechiae allows to achieve good anatomical results in most of the cases. The first risk of this surgery is perforation. However, obstetrical results are uneven; pregnancy rates are low in cases of complex synechiae. Endometrial ablation is performed in patients presenting with abnormal uterine bleeding after failure of progestin therapy. Pregnancies following endometrial ablation have been described; term deliveries are still exceptional.
