Screening for depression in mothers bringing their offspring for evaluation or treatment of depression.

OBJECTIVE: Numerous studies have shown that the highest risk for first onset of depression occurs in women of childbearing years and that there is a strong association between lifetime rates of depressive disorders in mothers and their offspring. This association is found regardless of whether the mother or child is the targeted patient. However, little is known about rates of current depression in mothers who bring their offspring to outpatient clinics for evaluation and/or treatment of depression. This information might be useful in developing intervention strategies. METHOD: One hundred seventeen mothers bringing their offspring for evaluation or treatment for depression were screened with the Patient Problem Questionnaire to determine current symptoms of depression, anxiety disorders, and substance abuse as well as current psychiatric treatment. RESULTS: Thirty-six (31%) of the mothers screened positive on the Patient Problem Questionnaire for a current psychiatric disorder. Sixteen (14%) screened positive for current major depression, 20 (17%) for panic disorder, 20 (17%) for generalized anxiety disorder, two (2%) for alcohol abuse, and one (1%) for drug abuse. In addition, 50 (43%) of the mothers had psychiatric symptoms that did not meet the diagnostic threshold for any of the above disorders. Twenty-six (22%) of mothers expressed suicidal ideation or intent. Only five (31%) of the 16 mothers diagnosed with major depression were currently receiving any psychiatric treatment. CONCLUSIONS: A substantial number of mothers bringing their offspring for evaluation or treatment of depression were themselves currently depressed and untreated. The treatment of depressed mothers may help both the mothers and their depressed offspring.

[Severe precocious pre-eclampsia : how to manage the feto-maternal conflict of interest].

BACKGROUND: The HELLP syndrome is usually treated by rapid termination of pregnancy as the most effective way of limiting the risk of disease aggravation and maternal complications. The drawback is the risk of fetal complications due to prematurity when pregnancy is terminated before 32 weeks gestation. A controlled study has suggested that corticosteroid therapy could be effective in early HELLP syndrome. PATIENTS AND METHODS: From January 1, 1996 to March 1, 1999, we treated patients presenting early HELLP syndrome defined as platelet counts below 150,000 and ALAT above 50 U/l prior to 32 weeks gestation with dexamethazone (Soludecadron((R))) via intravenous administration of 10 every 12 hours to the end of pregnancy or until platelet counts rose above 150,000. RESULTS: Among 14 patients with early HELLP syndrome, 10 were treated (including 5 primiparous women). Six patients among the 10 had platelet counts between 50,000 and 100,000. Mean term at the first injection of dexamethazone was 29 weeks 3 days. Platelet counts rose and transaminase levels fell in all patients. Pregnancy was prolonged 7 2 days. The only maternal complication was one case of disseminated intravascular coagulation. There were no neonatal deaths. DISCUSSION: Our results are similar to those reported in the literature but such a treatment scheme can only be instituted within a rigorously controlled monitoring system in a unit with neonatal and maternal intensive care facilities. This protocol remains safe for patients with HELLP syndrome whose platelet count remains at least above 50,000.

[Validation of laparoscopic surgery in gynecology].

Laparoscopic surgery is presently the gold standard for treatment of benign adnexal pathologies although the evaluation of other surgical techniques such as laparoscopic assisted hysterectomy or myomectomy remains to be made. Multicenter observational studies and data collection should be pursued to evaluate these new surgical techniques as they spread from a few promoting centers.

T cell status influences colon tumor occurrence in min mice fed short chain fructo-oligosaccharides as a diet supplement.

We have previously shown that addition of short chain fructo-oligosaccharides (indigestible carbohydrates) to food prevented colon tumors in C57BL/6-Apc(Min/+) mice, a model for human colon cancer. As gut-associated lymphoid tissue was concomitantly developed, we suggested that the immune response generated by this food may interfere with carcinogenesis due to involvement of mucosal cells in the regulation of tissue homeostasis. In the present experiment, we tested whether T cell status may influence colon tumor formation in Min mice fed a food supplement of short chain fructo-oligosaccharides. Min mice depleted of CD4(+) and CD8(+) lymphocytes developed twice as many tumors as immunocompetent mice (0.8 as compared with 0.4, the mean number in 7-week-old Min mice when food supplementation began; P = 0.02). It is concluded that food supplementation with a substrate (a known prebiotic) fermented in the colon may stimulate a mechanism of immunosurveillance that would otherwise remain inefficient.

Gastrointestinal injuries during gynaecological laparoscopy.

A retrospective case review study was carried out on gastrointestinal injuries which occur during gynaecological laparoscopy. Fifty-six patients with 62 gastrointestinal injuries were identified. One-third of the complications (32.2%) occurred during the installation phase for laparoscopy. Four of the six complications attributed to electrosurgery were secondary to the use of monopolar coagulation. Diagnosis of these gastrointestinal injuries was made during surgery in only 20 patients (35.7%). The mean time before diagnosis was 4.0 +/- 5.4 (range 0-23) days. Treatment of these complications was performed by laparoscopic surgery in 16.1% of cases. Prevention relies on the surgeon's experience, strict observance of the safety rules, perfect familiarity with the physical properties of the instruments used, systematic use of bowel preparation for patients presenting a risk of bowel complications, systematic supervision of the route taken by the trocars, meticulous inspection on completion of surgery of all areas where bowel adhesiolysis has been used and, in case of any doubt, tests for leakage involving the rectosigmoid. For patients with a risk of bowel complications, the creation of a pneumoperitoneum and performing a mini laparoscopy in the left hypochondrium can be the judicious option.

Screening for psychologically traumatized rape victims.

OBJECTIVE: This study aimed to determine whether the General Health Questionnaire, a simple psychological screening instrument, could be useful to non-specialists in screening for psychologically traumatized rape victims. STUDY DESIGN: 285 rape victims (mean age 22.5, men 8%) attending consecutively a Consultation for Victims of Psychological Trauma at the University Hospital in Tours, France, were assessed through the Structured Interview for Post-Traumatic Stress Disorder (SI-PTSD), and the French 28-item version of the self-rated General Health Questionnaire (GHQ-28). RESULTS: 70% had Post-Traumatic Stress Disorder (PTSD) and 72% a GHQ-28 overthreshold score. The principal component analysis of the GHQ-28 ratings yielded a 4-factor solution: social dysfunction, feeling of foreshortened future type of depression, somatoform complaints and hyperalertness anxiety. GHQ-28 reliability and validity in screening for PTSD were studied through computation of Cronbach's alpha coefficient (0.95), sensitivity (88%) and positive predictive value (86%). CONCCLUSION: Using the GHQ-28 is valid and appropriate for practical use.

Surgical complications of diagnostic and operative gynaecological laparoscopy: a series of 29,966 cases.

A multicentre study was carried out in seven top French centres for laparoscopic gynaecological surgery. This series covers a period of 9 years, in which 29,966 diagnostic and operative laparoscopic operations were performed. The risk of complications has been assessed according to the complexity of the laparoscopic procedure in question. The means of diagnosis and treatment of the complications have been analysed, together with the importance of the surgeon's degree of experience. The mortality rate was 3.33 per 100,000 laparoscopies. The overall complication rate was 4.64 per 1000 laparoscopies (n = 139). The rate of complications requiring laparotomy was 3.20 per 1000 (n = 96). The complication rate was significantly correlated with the complexity of the laparoscopic procedure (P = 0.0001). One in three complications (34.1%; n = 43) occurred while setting up for laparoscopy, and one in four (28.6%) were not diagnosed during the operation. As new indications for laparoscopic surgery in gynaecology have appeared, there has been a parallel and statistically significant increase in the rate of urological complications (P = 0.001). Increased experience by the surgeons has had three consequences: a statistically significant drop in the number of bowel injuries (P = 0.0003), a drop in the rate of complications requiring laparotomy for those laparoscopic surgical procedures that are well defined (P = 0.01), and a change in the way complications are treated, with a significant increase in the proportion of incidents treated by laparoscopy (P = 0.0001).

Short-chain fructo-oligosaccharides reduce the occurrence of colon tumors and develop gut-associated lymphoid tissue in Min mice.

C57BL/6J-Min/+ mice, which are heterozygous for a non-sense mutation in the Apc gene, provide a model for both familial adenomatous polyposis and sporadic colon cancers. In our study, gut tumors and small intestine lymphoid nodules were counted in Min mice fed fiber-enriched diets for 6 weeks. Neither starch-free wheat bran nor resistant starch modified the number of tumors. However, short-chain fructo-oligosaccharides dramatically reduced the incidence of colon tumors and concomitantly developed gut-associated lymphoid tissue. Our experiment shows that short-chain fructo-oligosaccharides counteract advanced stages of colon carcinogenesis, possibly via stimulation of antitumoral immunity by modulation of the colonic ecosystem.

Intrahepatic cholestasis of pregnancy: a French prospective study.

The aim of this prospective study was to analyze the characteristics of intrahepatic cholestasis of pregnancy (ICP) in a French population. From 1989 to 1995 we studied 50 consecutive pregnant women with ICP (41 single, 7 twin, and 2 triplet pregnancies) referred for hepatologic consultation. All patients suffered from pruritus and/or jaundice associated with elevated fasting serum levels of total bile acids (mean 49 micromol/L, range 7-290). No patients had concomitant liver disease and all recovered normal liver function after delivery. Overall prematurity rate was 60%: 100% in multiple pregnancies and 41% in single pregnancies. Three of 61 babies died. Systematic clinical interviews revealed that 34 patients had been treated with oral micronized natural progesterone (200-1,000 mg/d) during the current pregnancy for risk of premature delivery, including at least 32 (64%) before the onset of pruritus. Onset of pruritus was statistically earlier in patients previously receiving progesterone than in patients not receiving progesterone (217 +/- 21 vs. 240 +/- 26 days, P < .01). This was also found in the single pregnancy subgroup of patients (222 +/- 19 vs. 240 +/- 26 days, P < .05). Pruritus disappeared before delivery in 10 of 50 patients, i.e., after withdrawal of progesterone in 7 patients (only one concurrently treated with cholestyramine), after decrease in dose of progesterone in 1 patient, and spontaneously in 2 patients. During the same period, the percentage of pregnant women without ICP who had been treated with progesterone during pregnancy was statistically lower than the percentage of patients treated with progesterone before the onset of pruritus in our group of patients with ICP (36% vs. 64%, P < .01, odds ratio 3.16, 95% CI:1.29-7.80). These results suggest that orally administered progesterone might be an exogenous factor which triggers ICP in predisposed women.

Endocervical infection in a pregnant woman caused by Neisseria meningitidis: evidence of associated oropharyngeal colonization of the male partner.

A case of premature birth associated with an endocervical infection caused by Neisseria meningitidis is reported. Treatment of the mother with amoxycillin eradicated the bacteria from the endocervix and avoided newborn colonization or infection. Epidemiological investigation identified meningococcal oropharyngeal colonization of the male partner. The two strains were of the same antigenic formula B:4:P1.14 and exhibited identical rDNA restriction fragment patterns and outer membrane protein profiles. This phenotypic and genomic identity of strains is the first clear evidence for cross-colonization between sexual partners.
