Spontaneous uterine rupture in a patient with polyhydramnios as only risk factor. Case report, literature review and institutional experience

The uterine rupture is a catastrophic obstetric complication. The main risk factor is an antecedent of uterine surgery, usually caesarean. It is reported the case of a 39-years-old patient with 37 week-pregnancy and polyhydramnios, without surgical antecedents, whose was not in labor and developed complete rupture of the lateral face of the uterus, which was spontaneous, without previous uterine scar and with a unusual outcome.     

Análisis de los factores de influencia sobre el resultado de 500 ciclos de inseminación intrauterina homóloga

Objective

To evaluate the results and analyse different factors influencing pregnancy rate using homologous intrauterine insemination.

Subjects and methods

Retrospective analysis of 500 homologous intrauterine insemination cycles in 183 infertile couples. Only one insemination per stimulated ovarian cycle was performed in patients with: mild endometriosis, ovulatory factor, male subfertility or unexplained infertility. We studied female age, duration of infertility, stimulation protocol, number of cycle, number of preovulatory follicles, motile sperm count and endometrial thickness related to pregnancy rate.

Results

Pregnancy rate per couple was 24% and per intrauterine insemination 9%, 11% was multiple pregnancies. Best outcome has been got in women younger than 37 years (P=.048) and in cycles with more than one preovulatory follicle. Other studied factors did not have influence in homologous intrauterine insemination outcome.

Conclusions

Female age is a prognostic factor for homologous intrauterine insemination with poor outcome in women older than 38 years. Cycles with more than one preovolatory follicle have better outcome. No differences in pregnancy rate have been achieved with motile sperm count over 1.5 millions/0.3 ml.     

Spontaneous regression of a breast carcinoma: a case report

Spontaneous regression of malignant tumors is a rare event. It is defined as partial or total disappearance of a proven malignant tumor without adequate medical treatment. The causes of this phenomenon are various. Nevertheless, malignant tumors do regress occasionally for no apparent reason, as evidenced by many clinical observations. We report a case of a 68-year-old woman, who was presented with a several-month history of a painless firm lump, initially of 1 cm in diameter and growing to a large solid regular tumor of 2.5 x 2.5 cm in size, in the upper outer quadrant of her right breast. Preoperative histopathological diagnosis revealed ductal invasive carcinoma. Later on, while awaiting surgical treatment, she suffered an arm injury requiring a 1-month delay of surgery. After recovery, on the date of surgery the tumor disappeared, and, in addition, it was not found in tissue specimens obtained from quadrantectomy. After 78 months of follow-up there was no evidence of relapse. In this report, we discuss clinical and histopathological findings, patient management and possible mechanisms of cancer regression.     

Association of ovarian and uterine cancers with postmenopausal hormonal treatments

During hormone treatments for the relief of the symptoms of postmenopausal women a number of side effects may occur. Some may be due to the wrong choice of the steroids used for treatment or to the route of administration. However, the more important ones deserving much attention are the rare occurrences of malignancies of the uterus and ovaries. The risk for ovarian cancer, if it exists, is minimal and clinically irrelevant. Estrogen only treatments are used only in hysterectomized women. Continuous combined estrogen-progestin treatments have a very low risk of association with endometrial cancers compared with sequential regimens. Tibolone may be associated with a very small risk for endometrial cancers and thus must be properly monitored by transvaginal ultrasound. Breast cancer patients being treated with tamoxifen require careful attention to the endometrium to exclude a carcinoma. For the protection of the endometrium, a progestin-releasing intrauterine devise is an attractive choice. Raloxifene used for a long time to prevent osteoporosis is safe for the endometrium. None of the above-mentioned side effects is enough to prevent a physician from using hormone treatment in postmenopausal women if there are no past or current contraindications.

Preventive Strategies Against Cytomegalovirus and Incidence of α‐Herpesvirus Infections in Solid Organ Transplant Recipients: A Nationwide Cohort Study

We assessed the impact of antiviral preventive strategies on the incidence of herpes simplex virus (HSV) and varicella‐zoster virus (VZV) infections in a nationwide cohort of transplant recipients. Risk factors for the development of HSV or VZV infection were assessed by Cox proportional hazards regression. We included 2781 patients (56% kidney, 20% liver, 10% lung, 7.3% heart, 6.7% others). Overall, 1264 (45%) patients received antiviral prophylaxis (ganciclovir or valganciclovir, n = 1145; acyclovir or valacyclovir, n = 138). Incidence of HSV and VZV infections was 28.9 and 12.1 cases, respectively, per 1000 person‐years. Incidence of HSV and VZV infections at 1 year after transplant was 4.6% (95% confidence interval [CI] 3.5–5.8) in patients receiving antiviral prophylaxis versus 12.3% (95% CI 10.7–14) in patients without prophylaxis; this was observed particularly for HSV infections (3% [95% CI 2.2–4] versus 9.8% [95% CI 8.4–11.4], respectively). A lower rate of HSV and VZV infections was also seen in donor or recipient cytomegalovirus‐positive patients receiving ganciclovir or valganciclovir prophylaxis compared with a preemptive approach. Female sex (hazard ratio [HR] 1.663, p = 0.001), HSV seropositivity (HR 5.198, p < 0.001), previous episodes of rejection (HR 1.95, p = 0.004), and use of a preemptive approach (HR 2.841, p = 0.017) were significantly associated with a higher risk of HSV infection. Although HSV and VZV infections were common after transplantation, antiviral prophylaxis significantly reduced symptomatic HSV infections.     

Major hepatic resection for hilar cholangiocarcinoma: analysis of 46 patients

HYPOTHESIS: Major hepatectomy, bile duct resection, and regional lymphadenectomy for hilar cholangiocarcinoma are associated with actual long-term (>5 years) survival. DESIGN: Retrospective outcome study. SETTING: Single tertiary referral institution. PATIENTS: Between 1979 and 1997, 46 consecutive patients had resection of hilar cholangiocarcinoma by major hepatectomy, bile duct resection, and regional lymphadenectomy. MAIN OUTCOME MEASURES: Overall survival and tumor recurrence were correlated to clinicopathological factors, operative morbidity, and mortality. RESULTS: Twenty-five patients underwent left hepatectomy, 17 underwent right hepatectomy, and 4 had extended right hepatectomy. Eighteen patients underwent resection of segment 1. Negative (R0) resection margins were achieved in 37 patients (80%). The operative mortality rate was 9%, and the surgical morbidity rate was 52%. Actual 1-year, 3-year, and 5-year survival rates were 80%, 39%, and 26%, respectively. Factors adversely associated with patient survival rates included: male sex, lymph node metastases, tumor grade 3 or 4, elevated direct serum bilirubin level at diagnosis, elevated preoperative activated partial thromboplastin time, and more than 4 U of red blood cells transfused perioperatively. Tumor size and R0 resection approached significance for survival. Factors associated with tumor recurrence included: male sex, tumor grade 3 or 4, a low hemoglobin level both at diagnosis and preoperatively, and a low preoperative prothrombin time and low alkaline phosphatase level at diagnosis and preoperatively. Median time to recurrence was 3.6 years. Tumor recurrence was predominantly local and regional. CONCLUSIONS: The actual 5-year survival rate of 26% justifies major partial hepatectomy, bile duct resection, and regional lymphadenectomy for hilar cholangiocarcinoma. The high frequency of local and regional recurrence warrants investigation of adjuvant therapy.
