[Value of differential cytology in the diagnosis of preclinical forms of cervix uteri cancer].

The value of "differential cytology" in the diagnosis of preclinical carcinoma of the cervix uteri was assessed from serial sections of operative specimens in a series of 452 patients. Although not absolute, this value was found to be considerable. Used to supplement colposcopy-guided biopsy, it makes it possible to decide on the therapeutic approach (notably simple destruction by laser) without having recourse to conization. However, the results are only valid for the team which presents them, and before deciding to treat intra-epithelial carcinomas by laser destruction, each team must perform the same "quality control".

[Ovarian cancer: anatomo-clinical classifications].

There are important barriers in the correct evaluation of the anatomic involvement of malignant ovarian tumors. Nevertheless, it seems advisable to rationalise the criteria of involvement. The authors relate the past classifications of Heyman, Helsel, Munnel, Davis, Gellé, Rutledge and Burns. The most widely accepted present-day classifications are the TNM system of the UICC and above all that of the FIGO. It seems that an attempt at unification between the two systems is recommendable. However, all classifications are arbitrary in nature because of the very diversity of carcinoma of the ovary.

Simultaneous onset of ulcerative colitis in the rectum and in a segment of colon used for colpopoiesis: report of a case.

A patient is described in whom a segment of colon used to construct an artificial vagina was therefore removed from intestinal continuity and was affected by typical idiopathic ulcerative colitis. The onset of disease was simultaneous in this loop of colon and in the rectum. There was no evidence of local infection. An increased ratio of IgE-plasma cells was found in both the mucosa of the grafted colon and that of the rectum, but anticolonic antibodies were not detected in the serum. After removal of the loop of colon used for colpopoiesis, the patient continued to suffer from distal proctocolitis for almost a year, but has since then maintained a stable remission without treatment. The etiology of ulcerative colitis is discussed, and attention is drawn to the unusual psychologic aspects of this case.

[Gonadic dysgenesis and dicentric chromosome Y. A report of two cases, one of which had a gonadoblastoma (author's transl)].

The authors report two new cases of primary amenorrhoea due to the presence of a dicentric Y with a chromosome formula of 45,X/46,X,dic(Y). These two patients show how variable the clinical manifestations of these gonosome anomalies can be, since one had a Turner's syndrome and the other is a woman who looks completely normal but only has primary amenorrhoea. A review of the literature has brought to light only 45 cases similar to ours and shows the different clinical aspects of these patients who are 45,X/46,Xdic(Y). Finding that one of our patients had a gonadoblastoma has confirmed the need to carry out bilateral castration when there is a dysgenetic gonad with a Y chromosome, in order to treat or prevent a dysgenetic tumour from arising.

[Uterine and sigmoid perforations following voluntary interruption of pregnancy by aspiration. A case report (author's transl)].

A recent case of mixed uterine and colic perforations associated with generalized peritonitis is reported, the lesions developing within the context of the digestive complications of the method known as aspiration for voluntary interruption of pregnancy. The frequency, severity, and treatment of these lesions are described, urgent laparotomy being necessary to correct both abdominal digestive tract and genital lesions. Prevention of these complication technique. Coelioscopy is essential if a perforation is suspected, and must be followed by a laparotomy if its presence is confirmed.

[Prolapse after hysterectomy. A study of 45 cases (author's transl)].

The authors report 45 cases of prolapse occurring after hysterectomy (26 after subtotal hysterectomy, 9 after total abdominal hysterectomy and 10 after total vaginal hysterectomy). These prolapses are rare and their incidence does not seem to vary with the type of hysterectomy that preceded them. although in some cases hysterectomy could be incriminated as the cause of the prolapse, in the majority of cases the reason was a prolapse that had been neglected when the hysterectomy had been carried out, or a prolapse that appeared a long time after hysterectomy because of the inevitable ageing of the supporting tissues of the pelvis. From the anatomical point of view it is important to distinguish those prolapses where the vaginal vault does not descend and those where there is total descent including the vault of the vagina. The prolapses give rise to difficult problems of therapy. The choice of operation has to take into account anatomical components of the prolapse, the functional repercussions, the urinary symptoms and whether the patient wishes to does not wish to continue sexual activity. If it is not necessary to keep the vagina open an operation that involves colpectomy or colpocervicectomy can give rise to very good anatomical and urinary results. When it is necessary to keep the vagina functioning as a vagina in the case of prolapse after subtotal hysterectomy, it is important to treat the case as though on was dealing with an ordinary prolapse. All the same, when dealing with procidentia it may be wiser to add a colpopexy procedure by the abdominal route. When dealing with a prolapse after total hysterectomy when the vaginal vault is in place, it is sufficient to carry out the usual form of perineal plastic operation general;y to obtain a good result, but when the vaginal vault has come down it is as well to carry out a colpopexy procedure by the abdominal route.

[Tubal epithelium. Scanning electron microscopy in the menstrual cycle, in pregnancy and in the menopause (author's transl)].

The Fallopian tubes of 18 women who were either in reproductive age or were menopausal were studied by scanning electron microscopy. There were different cells seen in the epithelium. These were ciliated and non-ciliated cells, and cells, with a single cilium which was central and cells with short cilia. These elements undergo cyclical changes: secretory phenomena are at their maximum during the ovulatory phase. There is no sudden desquamation in tubal epithelium, nor is there massive deciliation. All the same, there are images that look like marguerites (described in the text) which are evidence of cellular regeneration. The appearance suggests a state of rest in precocious menopausal women and in pregnancy. The phenomena seen during the secretory phases disappear and the distribution of the cells is modified. Deciliation is found 20 to 30 years after the menopause. The physiological significance of these phenomena is still uncertain and their role in pathology has still to be defined.

[Tumours of the ovary in young women. The way they arise and the limits of conservative treatment (author's transl)].

Although tumours of the ovary are rare in woman under the age of 35 they are not exceptional and they form 15 p. 100 of the cases (17 patients) out of a series of 112 tumours of the ovary which were collected in 7 years. 11 of these patients had only one ovary affected and were able to be treated conservatively. In this way 5 of them were able to carry one or more pregnancies to term and another patient who was lost from observation for two years had to have a second operation to deal with a recurrence in the opposite ovary. Conservative treatment is only permissible if one is absolutely sure that the contro-lateral ovary is normal, and if there is the slightest doubt ovariotomy should be carried out to perform a biopsy. Furthermore the authors suggest that in view of the difficulties of strict supervision for a long term the opposite ovary and tube should be removed and hysterectomy carried out once the patient has had one or two children or when they have reached the age of 40.

[The obstetrical future of women who have been operated on for uterine synechiae. 107 cases operated on (author's transl)].

The authors undertake to show that the obstetric future of women who have been operated on for uterine synechiae is not as poor as would appear from previous publications. 59 p. 100 of 75 women who wanted to become pregnant did so and 46 p. 100 went on to have at least one living child. If one only takes into account those women who were able to be followed up, 71 p. 100 became pregnant and 55 p. 100 had pregnancies with a viable child. When women with only uterine synechiae and without an associated lesion were considered, 81 p. 100 of them became pregnant and 67 p. 100 had a viable child. From this it is important to screen for an associated lesion by laparoscopy. The authors also write about the value of hysteroscopy carried out to find synechiae more easily and to control the treatment.

[The heterogeneity of micropolycystic ovary syndrome. 77 cases (author's transl)].

Seventy seven cases of micropolycystic ovaries were reviewed. All of the patients underwent either coelioscopy or wedge resection of the ovaries. It was thus possible to classify the patients into two groups on the basis of the size of the ovaries (MPCO-A, large ovaries, more than twice the normal size; MPCO-B, ovaries only slightly increased in size or normal). There were differences from a clinical, laboratory and therapeutic standpoint. In MPCO-A, spaniomenorrhea predominated, clinical hyperandrogenism was often absent and 17 ketosteroids lower. Response to hypothalamic gonadotrophic hormone liberation factor was explosive in luteotrophic hormone, but at 120 minutes levels were lower in MPCO-A than in MPCO-B. Wedge resection failed completely in 23% of cases of MPCO-A and in 66% of cases of MPCO-B. This study confirmed current concepts of the heterogeneity of MPCO syndrome.
