Antioxidant activities and lipid peroxidation status in human follicular fluid: age-dependent change.

Maternal age is a significant factor influencing in vitro fertilization (IVF) outcomes. Oxidative stress (OS) is one of the major causes of age-related cellular and molecular damage. The purpose of this work was to investigate the correlation between maternal age with intrafollicular antioxidants and OS markers in follicular fluid (FF), and also to determine the OS status in patients of advanced age. This study was a prospective study including 201 women undergoing IVF whose age was between 24 and 45 years old. FF samples were obtained from mature follicles at the time of oocyte retrieval. After treatment of FF, lipid peroxidation levels (MDA) and enzyme activities such as superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR) and glutathione (GSH) level were evaluated using spectrophotometry. The results indicated that the age cutoff point for increasing the MDA level was fixed at 37 years, allowing the study to be differentiated into two age groups. Group I included patients whose age was less than 37 years, and group II included patients whose age was greater than or equal 37 years. Statistical analysis revealed that MDA and GSH levels and GR activity were significantly higher in group II compared with group I. The SOD and CAT activities were significantly less in group II compared with group I. We concluded that from 37 years old a reproductive ageing was accompanied by a change in the antioxidant pattern in FF that impaired reactive oxygen species scavenging efficiency.

Impact of alcohol and cigarette smoking consumption in male fertility potential: Looks at lipid peroxidation, enzymatic antioxidant activities and sperm DNA damage.

Alcohol intake and cigarette smoking are the major lifestyle factors with negative impact on fertility. We were interested to evaluate the negative impact of these factors on oxidative stress (OS), enzymatic antioxidant activity (EAO) of spermatozoa and on its DNA damage. This study included 108 male infertile patients with normal range of sperm conventional parameters but with unexplained infertility in assisted reproductive technologies programme. Firstly, OS was analysed based on lipid peroxidation (MDA) and EAO which included catalase (CAT), superoxide dismutase (SOD) and glutathione reductase (GR). Secondly, we evaluated DNA fragmentation by TUNEL assay and chromatin decondensation by aniline blue colouration. The whole lot was divided into four groups: control (nonalcoholic and nonsmoker patients), alcohol group, smoking group and alcohol-smoking group. The results showed, in three last groups compared to control an increased CAT, SOD and GR activities with high MDA level especially in smoking and alcohol-smoking group. The latter showed the highest values of DNA fragmentation and chromatin decondensation (31% and 39%) to exceed DNA damage normal range. Indeed, smoking and alcohol intake lead to increase EAO due to long-term unbalanced antioxidant/oxidation ratio with high OS which cause consequently sperm DNA damage calling in need by urgency to change the lifestyle behaviour.

Effect of semen preparation technique and its incubation on sperm quality in the Moroccan population.

In in vitro fertilisation (IVF), sperm preparation as critical part and influencing the sperm quality is especially dependent on the chosen technique itself and incubation parameters including temperature and CO2. In this study, we compared firstly density-gradient centrifugation technique (DGC) to the adapted DGC using the sperm pellet of 80% fraction (DGC/80P) in order to improve the sperm yield. Secondly, this study led to evaluate different sperm incubation conditions based on temperature effect (room temperature (RT = 23°C) versus 35°C) and in the other hand, with or without 5% CO2 during 24 hrs. Based on evaluating sperm conventional parameters and the DNA damage using TUNEL assay, our result showed that DGC/80P increased sperm quality compared to DGC with 25% of improvement. For temperature incubation effect after 24 hrs, 35°C increased the DNA damage and decreased the sperm quality while RT could improve sperm motility by 38%. Moreover, the sperm incubation with 5% CO2 after 24 hrs realised a negative impact on sperm parameters and its DNA damage. Indeed, for current IVF practice, a good sperm quality can be maintained for several hours at room temperature, while the sperm preparation is processed using the DGC/80P without CO2.

[Pregnancy in rudimentary uterine horn: diagnostic and therapeutic difficulties]. / Grossesse sur corne utérine rudimentaire: difficultés diagnostiques et aspects thérapeutiques.

Ectopic pregnancy in a rudimentary uterine horn is extremely uncommon. Implantation of one embryo in the uterine cavity and of another in a rudimentary uterine horn is an extremely uncommon form of twin pregnancy. The authors report three cases of pregnancies in a rudimentary uterine horn. One was associated to a heterotopic pregnancy in the other eutrophic horn. Through these three cases, they report the risks incurred and the difficulties of the assumption of responsibility of this type of pathology, on the diagnostic as well as therapeutic level. But generally underline the interest of echography especially endovaginale and the coelioscopy in the early diagnosis of this type of uterine malformation.

[Severe neonatal myasthenia with arthrogryposis]. / Myasthénie néonatale sévère avec arthrogrypose: à propos d'un cas et revue de la littérature.

Maternal myasthenia gravis has been associated with the presence of neonatal myasthania and sometimes fetal congenital anomalies. The purpose of this paper is to present an infant with multiple deformations born to a mother with myasthenia gravis. The infant presented with arthrogryposis multiplex and pulmonary hypoplasia. The new born died within the first day of life. Twenty-seven other cases of neonatal myasthenia with arthrogryposis have been reported. Twenty-two of them were stillborn or died. The surviving children needed ventilatory assistance for a long period.

[Heterotopic pregnancies: 8 cases]. / Grossesses hétérotopiques: à propos de huit cas.

Heterotopic pregnancy is the combination of intra-uterine pregnancy and ectopic pregnancy in the same patient whatever is the localization of the ectopic pregnancy. The aim of this work was to summarize the epidemics and clinical factors, the diagnostic means and the therapeutic methods for the spontaneous heterotopic pregnancy in Moroccan context. In a period of 6 years (1993-1998), 8 patients were treated for heterotopic pregnancy in Lalla Meryem Maternity of Casablanca, with a rate of 0.2/1000. Patients' ages ranged from 19 to 37. The backgrounds were: abortions (4 cases), secondary sterility (2 cases) and genital infection (2 cases). Five patients consulted for metrorrhagia associated with pelvic pain. Two for pelvic pain and one for metrorrhagia. The diagnosis was confirmed before echography in 5 cases. All patients were operated on, 3 in a condition of haemorrhagic shock. Ectopic pregnancy lay at the level of the fallopian tube in 7 cases and at the level of the ovary in one. The treatment consisted of a salpingectomy in the 7 patients with tubal localisations, the ovary pregnancy benefited from ovariectomy. Evolution has been marked by expulsion of intra-uterine pregnancy in 6 cases. Two women were able to carry out their pregnancy. Heterotopic pregnancy is more and more frequent because of genital infection increase and especially the wide diffusion of the assisted medical procreation.

[Vesico-uterine fistula of obstetrical origin. Report of 3 cases]. / Les fistules vésico-utérines d'origine obstétricale. A propos de 3 cas.

Vesico-uterine fistulae (VUF) lead to an abnormal breech between the bladder and the womb. They are responsible for urinary incontinence and/or cyclic hematuria. They are rare and, in most cases, lead to complications following caesarean deliveries. We report observations of 3 vesico-uterine fistulae treated over a 5 years period at university maternity based at Casablanca, Morocco; they all occurred following caesarean deliveries. These patients were consulted for urinary leakage occurring few weeks up to many years following surgical traumatism. Diagnosis was evoked clinically in all cases and confirmed by intravenous urography and/or hysterography. These VUF were successfully treated by simple breech suture at laparotomy. Treatment is very simple and efficient when the diagnosis is made early and fistula simple. Surgery is recommended after medical treatment failure aiming at fistula drainage.

[Pelvic lymphocele: report of a case and review of the literature]. / Lymphocèle pelvienne: un diagnostic à ne pas méconnaître! A propas d'un cas et revue de la littérature

Lymphadenectomy for pelvic cancer can lead to complications, particularly lymphocele. We report a case of pelvic lymphocele, which occurred in a patient who underwent surgery for stage IIa cervical carcinoma after preoperative radiotherapy. The intervention consisted in colpohysterectomy, with lymphadenectomy without peritonisation. Five months later she developed dysuria and pelvic pain. Ultrasound and computed tomography showed a pelvic lymphocele complicated by renal insufficiency. Kidney function was re-established after intraperitoneal marsupialisation. One year later the patient was in good clinical condition with no disorder of kidney function.

[Current profile of obstetrical vesicovaginal fistulas at the maternity unit of the University of Casablanca]. / Profil actuel des fistules vésicovaginales obstétricales à la maternité universitaire de Casablanca.

Obstetrical vesicovaginal fistulas are secondary to dystocia. Late and inappropriate treatment are still a health public problem in under development countries. In five years (1993-1997), twelve vesicovaginal fistulas were repertored in the department of obstetrics and gynaecology of Casablanca (Morocco) with a frequency of 0.33@1000 deliveries and 2.4 new cases a year. 80% of the cases occurred after a long labour without efficient obstetrical care. Most of the cases (75%) were simple with an easy surgical treatment. All the fistulas were resolved after one or two surgical procedures realised by vaginal route in eight cases (2/3). During these last decades, with the efforts in obstetrical care in our country, we are assisting in a diminution of the frequency of this pathology and specially the number of complicated fistulas.

Hysteroscopic resection of submucosal myomas in patients with infertility.

BACKGROUND: Submucosal myomas are associated with infertility, and may be treated by hysteroscopic resection. Improvement of the menstrual pattern after surgery has been examined and compared with pregnancy rate in a group of menorrhagic women with primary (n = 24) and secondary (n = 35) infertility. METHODS: The entire patient group (n = 59) was managed between January 1990 and September 1998. The submucosal myomas were intracavitary (n = 15), intramural class 1 (n = 34) and intramural class 2 (n = 10), and none was multiple submucosal myoma. The mean (+/- SD) age was 36.6 +/- 4.6 years; mean myoma size was 24.5 +/- 13.3 mm; mean duration of the procedure was 40 +/- 23 min; and mean follow-up was 26 +/- 18.8 months. Thirty-five patients had one or more associated infertility factors. RESULTS: An improvement in clinical symptoms was observed in 62% of patients. Sixteen patients (27%) conceived, and of these only six (10%) delivered at term. The pregnancy rate was significantly better when myoma was the exclusive aetiology of infertility (41.6%), and when the lesion was >/=50 mm in size (57.1%). CONCLUSIONS: Hysteroscopic myomectomy appears safe, and is effective in the control of menstrual disorders. However, the effect on infertility seems limited, particularly in terms of delivery rate. The advanced age of the patients may partly explain these results.

[Pelvic hydatid yst: apropos of 8 cases]. / Kystes hydatiques pelviens: à propos de huit cas.

The hydatidosis fisues in the endemic state in Morocco, its pelvigenital localization is rare and doubtful. The objective of this study is to examine the epidemio-clinic appearance, the diagnosis means and the therapeutic flow of the pelvigenital hydatid cyst in Morocco. This retrospective study is about eight patients hospitalized and cured for pelvigenital hydatid cyst in lalla Meryem maternity of Casablanca during a period of six years (1992-1997). The hydatid cyst diagnosis was confirmed by anatomopathology. This affection represented 0.80% of the pelvic mass operated during the same periode. The majority of our patients was from rural origin, their age varies between 22 and 70 years old. The discovery circumstances were dominated by abdomino-pelvic mass. The diagnosis was nearly certain prior to the surgery for half of the cases. The genital organs were the most reached by the pelvic hydatidosis (75%). The treatment was purely surgical, adapted to each case in according to the localization, the volume and the contribution of the cyst. The medical treatment has been prescribed in one case in post surgery. The evolution was good in all the cases. The hydatidos cyst must always be present in mind when dealing with cyst pelvic formation in an endemic country like Morocco. The prophylaxia preserves its important value and must constitute a hinder against this disease in endemic countries.
