Live birth after allografting of ovarian cortex between monozygotic twins with Turner syndrome (45,XO/46,XX mosaicism) and discordant ovarian function.

Objective: To report the restoration of ovarian function in a woman with Turner syndrome by allografting ovarian cortex from her monozygotic twin.

Design: Case report.

Setting: Gynecology research unit in a university hospital.

[Current status of Wegener's syndrome. Apropos of 2 cases].

In the context of two recent cases, the authors briefly review the clinical, laboratory and anatomical features of Wegener's granulomatosis and, in particular, its clinical course in response to treatment. These 2 cases include fairly original features: one case presented with abundant haemoptysis with a radiological picture of extensive diffuse bilateral pneumonia; the other case presented with a very large pleural effusion with no E.N.

[Influence of the localization on the prognostic value of E, E-active and autologous rosettes in lung, esophagus and otorhinolaryngologic cancer].

E, E-active and autologous-rosette-forming-lymphocytes (E, Eact-, auto-RFC) were studied in 66 patients with lung cancer (2 stage I, 17 stage II, 20 stage III, 27 stage IV), 42 patients with head and neck cancer (14 stage III, 28 stage IV) and 22 patients with esophagus cancer (11 stage II, 6 stage III, 5 stage IV). Compared to controls, E-RFC were found to be depressed in each of the three different localizations (p less than 0.001), Eact-RFC were found to be depressed in head and neck as well as esophagus cancer (p less than 0,05 and p less than 0,01 respectively) and auto-RFC were found to be depressed in lung and esophagus cancer (p less than 0,01).

[Prognostic significance of lymphocytes forming "active rosettes" in lung cancer].

Lymphocytes forming E rosettes, active E, autologous and EA antibodies were studied in 66 subjects (56 men, 10 women, mean age 59, range: 40-85 years) who presented with lung cancer classified on the TMN scale in stages I and II: 19; stage III: 20; stage IV: 27. In comparison to the controls, there was a significant reduction (p less than 0.01) in E, autologous and EA rosettes in the patients.

[Branchiomeric mediastinal chemodectoma: a case report and literature review].

Among non-chromaffin paragangliomas, the so-called aorticopulmonary or branchiomeric mediastinal chemodectomas are very rare tumors. A case is reported, and 57 similar cases described in the literature are reviewed. As recommended by Olson, a separate group was instituted of 21 cases of the so-called posterior mediastinal or aorticosympathetic group of the costovertebral groove.

[Spontaneous abortion after intra-uterine transfer of an ovum fecundated in vitro (author's transl)].

Spontaneous expulsion of a human ovum fecundated in vitro and transferred into the uterus occurred after 10 1/2 weeks of amenorrhoea. The oocyte had been collected after stimulation by human menopausal and chorionic gonadotrophins (hMG and hCG). The techniques of pre-ovulatory oocyte collection, fecundation, in vitro culture and of reimplantation of the embryo are briefly described.

[Acquired ichtyosis and bronchial cancer; report on two cases (author's transl)].

Acquired ichtyosis appears to be a rather rare paraneoplasic syndrome, mainly observed during the course of Hodgkin's disease, but also accompanying visceral cancers. Two cases of generalised ichtyosis in patients with bronchial carcinoma are reported, emphasis being placed on the need for systematic investigations to determine this possible aetiology. Diagnostic problems are discussed, as well as hypotheses concerning the pathogenicity of these affections, which is still obscure, emphasis being placed on the secretory potential of these tumours and the role of immunological phenomena.

[Treatment of the syndrome of inappropriate secretion of antidiuretic hormone with demethylchlortetracycline. Apropos of 2 cases].

Two cases of inappropriate antidiuresis are reported, one associated with small cell anaplastic bronchial carcinoma, the other secondary to acute hydrocephalus. ttreatment with demethylchlortetracycline proved effective in both cases. Treatment of the inappropriate antidiuretic syndrome is discussed and the advantages of demethylchlortetracycline emphasised.

[Spontaneous pneumothorax in the adult. Problems of its development and treatment (apropos of 124 cases)].

The authors report their experience of the evolution and treatment of spontaneous pneumothorax in the adult, in a series of 124 cases, starting from January 1965 to May 1975. Recurrences occur in 27% of cases whatever therapeutics are used. They discuss frequency and modality in relation to the etiology and the proposed treatment of pneumothorax.
