Femtosecond coherent Raman spectroscopy and its application to porphyrins.
The results on femtosecond time-resolved coherent anti-Stokes Raman scattering (CARS) experiments for the analysis and control of ground state vibrational dynamics of porphyrin systems are briefly reviewed. By detecting the spectrum of the transient CARS signal, a detailed mapping of the dynamics initiated by the stimulated Raman pump process is achieved. The method yields the dephasing behavior and spectral information of the investigated system at the same time. The different contributions to the ground state vibrational dynamics are selected by changing the direction of the CARS signal analyzer in the polarization arrangement used.

[Effects of micronized natural progesterone on the liver during the third trimester of pregnancy].
In France, prescription of micronized progesterone at high doses of 900 to 1200 mg/day is common practice in the case of preterm delivery, even though this is neither an indication nor a posology given for marketing authorisation. A few cases of gestational pruritus have been reported during such use, associated with cholestasic and/or cytolytic hepatic disorders. We report here the results of a controlled, double-blind study versus a placebo, aimed at assessing the effects on the liver of micronized progesterone administered orally at high doses (900-1200 mg/day), conducted in a population of 201 women presenting moderate menace of preterm delivery during the third trimester of pregnancy. 85 patients received micronized progesterone and 116 the placebo. The increase above normal levels of total biliary acids (TBA) and aminotransferases (ASAT, ALAT), was significantly more frequent in the micronized progesterone than in the placebo group. Among the 26 patients (14%) with a level of TBA superior to 10 mumoles/l during treatment, 18 belonged to the progesterone and 8 to the placebo group (p = 0.004); the 6 patients (3.4%) with increased ASAT were all under micronized progesterone (p < 0.001), as were the 10 patients (5.6%) with increased ALAT (p < 0.001). However, there is no statistically significant difference between the two groups regarding the occurrence of clinical manifestations (icterus, pruritus) which could be attributed to gravid cholestasis. We may conclude from this prospective study that, during the third trimester of pregnancy, micronized progesterone is associated with a significant risk of biological cholestasis. This would suggest that in patients genetically predisposed towards gravid cholestasis, micronized progesterone could be a factor favoursing this disease.

[Acute aortic dissection during pregnancy. Surgical treatment with maternal and fetal rescue].
Acute aortic dissection (AD) seldom affects young women, but when it occurs it is, in almost one out of two cases, during pregnancy. We report a case of severe AD during pregnancy in which emergency surgery immediately saved the life of the mother and the foetus. The mother died of cardiac complications 13 days after the operation; the condition of the newborn is satisfactory.

[Pregnancy and non-Hodgkin's lymphoma: a case].
We report for the first time in the French literature the case of a malignant non Hodgkin's type lymphoma associated with pregnancy in a 19 year old woman. The evolution with corticotherapy was rapidly unfavourable and led to premature birth of a child who died 24 hours later, and to maternal death 48 hours later in spite of an attempt of chemotherapy. The prognosis of these tumours is bad, for the fetus because of the risks of premature delivery, for the woman because of the risks of tumoural evolution during the postpartum period.

[Inguinal hernia and endometriosis].
Endometriosis is an ubiquitary disease. It can be intra or extragenital. We report the case of a patient with an endometriosic nodule at the end of an inguinal hernia, there was no other sign. The diagnosis was done through pathology. The treatment, exclusively surgical was the cure of the hernia and the excision of the nodule.

[Abdominal ectopic pregnancy. Limits of laparoscopic treatment].
We report a case of early abdominal pregnancy (6 weeks amenorrhea). The diagnosis of ectopic pregnancy was suspected according to the usual clinical, serologic, and sonographic procedure. It was confirmed by laparoscopy. Laparoscopic surgery was unable to assess the trophoblastic site and the hemostasis of the lesion that was histologically proven.

[Takayasu's disease and pregnancy].
We report one case of pregnancy in a non-oriental woman who had Takayashu's disease. Pregnancy was characterised by toxemia and caesarean section had to be carried out at 31 weeks because of fetal distress. The disease did not worsen and nor were there any maternal complications but the child died on the 7th day.

[Breech extraction of the second twin with or without version by internal maneuvers].
A retrospective study was done to appraise the recent practice of breech extraction of the second twin (with or without internal version) in our unity. From January 1st, 1988 to April 30, 1991 23 patients with a twin gestation were delivered in our unity (0.5% of all deliveries). Nineteen patients (83%) were delivered vaginally. Each procedure was done by a resident under control of a senior obstetrician and in the presence of two midwives, a pediatrician, and an anesthesiologist. Ten patients having had a breech extraction (GE group) were studied, 13 patients were excluded for not having had a breech extraction. In the GE group the presentations were: 7 vertex/breech and 3 breech/breech. Mean Apgar scores of the second twin at 3 minutes were 8 in the GE group. These results suggest that breech extraction of the second twin is not a pernicious technique if done by trained operators with precise limits. These results need to be confirmed through a prospective randomized and comparative study.

Proportionate mortality among male corn wet-milling workers.
Workers in the corn wet-milling industry are exposed to grain dusts, pesticides and fumigants, acids, solvents, sulphur dioxide, and other chemicals used in the manufacture of starch, oil, syrup, and dextrins. In a preliminary investigation of the long-term health effects of occupational exposures in this industry, deaths among active and retired corn wet-milling workers were identified from records of a trade union. Underlying cause of death for workers who died between 1947 and 1981 was determined from death certificates. Cause-specific Proportionate Mortality Ratios (PMR's) were computed for white and black males using US males as a comparison with adjustments for age, race, and calendar year of death. There were deficits of deaths from respiratory and digestive diseases. Among whites, mortality from chronic nephritis, bladder cancer, and lymphatic and haematopoietic malignancies was elevated. There was an elevated frequency of deaths due to diabetes and a threefold excess of pancreatic cancer deaths among blacks. Crude work history information indicated a small cluster of pancreatic cancer deaths among whites and blacks who had worked in production processes that convert corn starch to syrup and dextrins. An elevated frequency of deaths from leukaemia was seen among white maintenance workers.

Accuracy of death certification in an autopsied population with specific attention to malignant neoplasms and vascular diseases.
Accuracy of certification of underlying cause of death and implications for US mortality statistics were assessed among 257 autopsied cases collected during the calendar year 1970 at a short-stay general hospital in Atlanta, GA. Clinicopathologic cause of death (CPCD) certificates, with assignment of underlying cause of death based on autopsy findings in combination with pertinent clinical data, were prepared by a pathologist and were employed as a standard of comparison against which the accuracy of the underlying cause of death on the original death certificate was measured. Results suggest that autopsy findings are not necessarily used to supplement clinical data in filling out death certificates. Improper recording of underlying cause of death was found in 42% of the autopsied cases. Malignant neoplasms were found to be underreported and vascular diseases overreported, each by approximately 10%, when original certificates were compared to CPCD certificates. The confirmation rate for original death certificate diagnoses was 89%. In the case of a confirmed diagnosis, the underlying cause of death was substantiated by postmortem findings as having existed regardless of its role in the sequence of events leading to death. The underlying cause of death as assigned by the pathologist was listed on the original death certificate among the sequence of events leading to or contributing to death at the rate of 72% (i.e., this rate measures the sensitivity of the death certificate).

Evaluation of multiple causes of death in occupational mortality studies.
An exploratory examination of the possibility of using multiple causes of death information from death certificates in mortality studies has been undertaken. The formation of a matrix of primary by contributory causes has been suggested. The matrix gives an overall picture of mortality patterns, serves as a scheme to identify disease combinations, and can be utilized as a data-editing device. From the matrix, several conventional, as well as several new statistics can be computed. The methodology has been illustrated with data from a cohort of steelworkers. The gain in information as a result of routinely recording multiple causes of death has also been discussed.
