Antioxidant status in relation to heavy metals induced oxidative stress in patients with polycystic ovarian syndrome (PCOS).

Polycystic ovary syndrome (PCOS) is a global health concern for women of reproductive age, as 6.5% of women worldwide are affected by this syndrome. PCOS is marked by hyperandrogenism, anovulation, menstrual abnormalities, and polycystic ovaries. Metals such as arsenic, cadmium, lead and mercury are considered to be systemic toxicants/human carcinogens and seem to have devastating effects on humans, even at minimal exposures. One of the probable aetiological factors for PCOS has been identified as oxidative stress. In view of the probable associations among oxidative stress, metal toxicity and PCOS, the present study examined the role of heavy metals in the generation of oxidative stress among females. This prospective study included 106 women (56 women diagnosed with PCOS and 50 women who were not diagnosed with PCOS as control women). There were no significant differences in the sociodemographic characteristics between the two groups except for the irregularity of menses and the presence of acne. The serum As, Cd, Pb, and Hg levels increased and the serum glutathione (GSH) and superoxide dismutase (SOD) levels diminished significantly in the PCOS group compared to the control group at P < 0.001. The SOD levels were negatively correlated with the As and Pb levels at P < 0.05. Additionally, the PCOS group exhibited a strong negative correlation between the GSH and As levels (P < 0.01), GSH and Pb levels (P < 0.05) and GSH and Hg levels (P < 0.01). Furthermore, the As levels were positively correlated with increased levels of Cd, Pb and Hg among PCOS women. Significant positive correlations were observed between Pb and Cd and between Cd and Hg at P < 0.001. The outcome of the study provides clear insight into the role of metal-induced oxidative stress, which plays a vital role in the pathophysiology underlying PCOS and suggests the use of these markers as prognostic tools to reduce the consequences of high-risk exposure to these metals among females.

The impact of obesity on reproduction in women.

Obesity can impact on reproductive functions by causing hormonal imbalance and ovulatory dysfunction. Furthermore, obesity is associated with a range of adverse health consequences. There is a tight coupling between the reproductive system and energy balance. Obesity results from chronic imbalance between energy intake and energy expenditure, and therefore changes in energy expenditure impact on the reproductive system. Physical activity, through its effect on energy expenditure, plays an imperative role in maintaining energy balance and thus improving health. It is therefore recommended that weight loss is the best and the cheapest therapy for infertile obese women.

Views of women towards cesarean section.

Women who deliver by cesarean section CS differ significantly from those who deliver vaginally regarding their childbirth experience. Those who deliver by CS are often less satisfied with their experience, and with themselves. They experience a feeling of resentment towards the physician, profound disappointment at the treatment expectation and loss of the happy moment of natural birth leading to postpartum depression. Cesarean delivery carries considerable disadvantages in terms of pain and trauma of an abdominal operation and complications associated with it. However, the CS rate is constantly on the rise. Hence, there is a need to evaluate the views of women undergoing cesarean deliveries and to ascertain the role of women in decision making regarding mode of delivery. This is a review of studies investigating the views of women from different countries towards CS and presents the view points of Saudi women regarding this.

Pelvic hematoma resulting in obstructive uropathy.

The use of anticoagulants, for whatever indication, may carry a high risk of hematoma formation following surgery. Obstructive uropathy is a very rare but possible example of complication secondary to an extensive pelvic hematoma. We describe a case of a patient with rheumatic heart disease and aortic valve replacement, who developed a massive postoperative pelvic hematoma following bilateral tubal ligation, resulting in bilateral ureteric obstructions. This was treated with bilateral ureteric stent through cystoscopy.

Disseminated intravascular coagulation and massive obstetric hemorrhage. Management dilemma.

OBJECTIVE: The objective of this retrospective study is to reflect on our experience on an optimal management for major postpartum hemorrhage, which would prevent the occurrence and complications of disseminated intravascular coagulation and minimize maternal mortality and morbidity. METHODS: Ten cases out of the 30,000 of total deliveries of severe obstetric hemorrhage associated with disseminated intravascular coagulation were studied. This study was carried out over a 7 year period, October 1988 through to September 1995, at the Obstetric Unit, King Khalid University Teaching Hospital, Riyadh, Kingdom of Saudi Arabia. RESULTS: All of the 10 women received packed red blood cells, 8 had fresh frozen plasma, and 6 received platelet transfusion. The 10 cases developed disseminated intravascular coagulation following medical and surgical management, all women needed hysterectomy, 4 subtotal, 6 total, and 5 women had relaparotomy and pelvic packing. Two had bladder injuries. There was no maternal death. CONCLUSION: An early resort to hysterectomy when conservative measures fail, will minimize maternal morbidity and mortality. In case of continuous bleeding after hysterectomy, pelvic packing proved to be effective.

Detection of genital colonization of group B streptococci during late pregnancy.

OBJECTIVE: To detect group B streptococcal carrier state of Saudi females during 3rd trimester of pregnancy and to assess type of specimens and the techniques used for the organism detection. METHODS: A total of 867 consecutive vaginal and rectal swabs were obtained from 217 pregnant women at > 28 weeks of gestation and their follow up testing from King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia. Swab-specimens were cultured comparatively on Islam and Edwards blood agar plates, and into selective Lim broth. Enrichment Lim broth cultures (>12 hours) with and without positive modified coagglutination test were then subcultured on Islam and Edwards sheep blood agar plates. Presumptive colonies were then tested for group B streptococcus identity by convential biochemical reactions, serogrouping and serotyping. Collected neonatal swab-specimens (184) were also treated similarly. RESULTS: In comparison to Lim broth enrichment culture, the direct swab specimen culture on Edwards blood agar or Islam agar plates technique revealed 84% sensitivity and 100% specificity, whereas modified coagglutination test after selective Lim broth enrichment revealed 100% sensitivity and 96% specificity. Group B streptococcus was isolated in at least one of the specimens from the 217 patients in 66 cases. Of these 66 cases, group B streptococcus was isolated from both vaginal and rectal swabs in 33 (50%) cases and only from vaginal swabs in 22 (33%) and rectal swabs in 11 (17%) cases. Of the group B streptococcus positive cases, 10 (15%) cases had spontaneously lost their carriage, upon follow up testing, whereas out of the 151 negative cases, 4 (2.6%) cases became positive for group B streptococcus colonization upon follow up testing with an overall carriage rate of (60/217) 27.6%. Certain demographic factors were found to alter such rate of carriage. Additionally, 50% of group B streptococcal colonized mothers vertically transmitted the homologous serotypes of the organism to their newborns, but clinical infection was not recorded during the study period. CONCLUSION: Group B streptococci colonization rate among term Saudi pregnant women is relatively high (27.6%); and thereby constitutes a group of women whose infants are at great risk of early-onset invasive disease. The modified coagglutination test after growth amplification seems rapid and cost-effective to detect lightly or heavily group B streptococcal colonized women. Vaginal and rectal swab specimens at late pregnancy appeared necessary to accurately identify group B streptococcus maternal colonization.
