Background: The role of Ca-125 in endometrial cancer is not fully known. Some authors have reported high Ca-125 levels in patients with recurrent or advanced endometrial cancer, whereas others have stated that Ca-125 levels and the advance of the disease were not correlated in endometrial cancer. This makes it inevitable for clinicians to search for different measurement methods or interpretation of the present tumor markers.

Background: Late correction of cleft lip nose deformity continues to be a challenge because of the weakness of cartilages and the collapsing forces of tight contracted soft tissues. The authors describe the new technique of costal cartilage spring graft for columella and lower lateral cartilage as a block to achieve symmetric, aesthetically more durable, and acceptable results for the late correction of cleft lip nose deformity.

Methods: Late cleft lip nose repair with simultaneous rhinoplasty was performed in 92 patients with unilateral cleft lip nose deformity.

Objective: Ductus venosus blood flow velocity measurements are mandatory in many clinical indications. The evaluation of the flow is performed either by comparing results with general reference tables or by qualitative assessment of the “a” flow, in regard to reversed or absent flow in the spectral waveforms. The aim was to develop normal reference ranges in low-risk pregnancies in our population.

Article Synopsis
  • The study examines the relationship between SCUBE1 levels and polycystic ovary syndrome (PCOS) in lean women, suggesting PCOS may signify an early stage of metabolic syndrome linked to cardiovascular issues.
  • Researchers analyzed 90 women with PCOS and 100 healthy controls, confirming that those with PCOS had significantly higher SCUBE1 levels (5.9 ng/mL) compared to controls (4.2 ng/mL).
  • Despite increased SCUBE1 levels in women with PCOS, the study found no correlation between SCUBE1 and hormonal or metabolic factors, implying its potential role as an early biomarker for future cardiovascular problems.

Article Synopsis
  • * Rats were divided into three groups: a control group, an EMR-only group, and an EMR + vitamin C group, with findings showing significant increases in oxidative stress markers in the EMR-only group.
  • * Results indicated that vitamin C treatment significantly reduced oxidative stress and the expression of harmful proteins (Caspase-3 and Caspase-8) in the ovaries and uterus, suggesting it may offer protective benefits against EMR-induced damage.

Article Synopsis
  • Cigarette smoking (CS) causes oxidative stress that negatively impacts the female reproductive system in a rat model, leading to changes like reduced follicle numbers and tissue damage.
  • In the study, female rats were divided into three groups: a control group, one exposed to CS, and one that received alpha lipoic acid (ALA) treatment after CS exposure.
  • The results showed that ALA effectively reversed the harmful effects of CS, suggesting it could serve as a protective agent against oxidative damage in the reproductive organs.

Uterine arteriovenous malformation (AVM) is defined as abnormal and nonfunctional connections between the uterine arteries and veins. Although the patients typically present with vaginal bleeding, some patients may experience life-threatening massive bleeding in some circumstances. The treatment of choice depends on the symptoms, age, desire for future fertility, and localization and size of the lesion; however, embolization of the uterine artery is the first choice in symptomatic AVM in patients at reproductive age with expectations of future fertility.
