Retroperitoneal tumors in the pelvis: a diagnostic challenge in gynecology

Retroperitoneal tumors can pose a diagnostic and therapeutic challenge to gynecologists because of their rarity, late presentation, and complex anatomical location in the retroperitoneum. This article reviews the diagnosis and management of retroperitoneal tumors in the pelvis, and highlights the potential pitfalls that may be faced by gynecologists.

GnRH analogs do not protect ovaries from chemotherapy-induced ultrastructural injury in Hodgkin's lymphoma patients

To determine the protective effect of gonadotropin-releasing hormone analogs (GnRHa) using several ultrasound and endocrine markers to detect ultrastructural ovarian damage in Hodgkin's lymphoma patients.

Specific secretory phase endometrial leukocytes of women with two and more consecutive idiopathic abortions are not significantly different from healthy controls

OBJECTIVE: To analyze concentrations of endometrial leukocytes in patients with idiopathic-repeated abortions. MATERIALS AND METHODS: Biopsies of exactly dated secretory endometrium in 25 patients with idiopathic-repeated abortions and 10 control patients without a history of miscarriage were compared with respect to the concentrations of T-helper cells (CD4), cytotoxic T-cells (CD8), B-cells (CD19) and uterine natural killer cells (CD56) by immunohistochemistry and RNase protection assays. RESULTS: All examined cells were detectable within secretory endometrium. No statistically significant differences of the examined immune-cell concentrations were seen between the control group and the repeated miscarriage group by either test. CONCLUSION: This study suggests that the concentrations of specific endometrial leukocytes in a non-pregnant cycle are not associated with repeated pregnancy loss. Thus, the hypothesis of an altered endometrial immunity in patients with repeated miscarriages, symbolized by persistently differing local immune-cell concentrations, has to be questioned.

Turning placenta into brain: placental mesenchymal stem cells differentiate into neurons and oligodendrocytes

We aimed to induce neural stem (NSC) and progenitor cells (NPC) from human placental tissues.

Suspicious axillary lymph nodes in patients with unremarkable imaging of the breast

The aim of this study was to evaluate the pathological findings and the method of tissue harvesting in those patients who have both suspicious axillary lymph nodes and normal imaging of the breast.

Dose-response effect of interleukin (IL)-1beta, tumour necrosis factor (TNF)-alpha, and interferon-y on the in vitro production of epithelial neutrophil activating peptide-78 (ENA-78), IL-8, and IL-6 by human endometrial stromal cells

The production of epithelial neutrophil activating peptide-78 (NA-78) and the interleukins IL-8 and IL-6 by endometrial stromal cells is stimulated by pro-inflammatory interleukin-1 (IL-1) and tumour necrosis factor-α (TNF-α). IL-8 is suggested to play a role in the pathogenesis of endometriosis, and in these women the peritoneal fluid concentrations of ENA-78 and IL-8 are increased. TNF-α has been tested together with interferon-γ because of their cooperative stimulation of IL-6. The release of IL-8, however, is inhibited with increasing interferon levels. The aim of the study was the analysis of the production of ENA-78, IL-6 and IL-8 by cultured human endometrial stromal cells in the presence of varying concentrations of IL-1β, TNF-α, and interferon-γ.

Neurogenic characteristics of placental stem cells in preeclampsia

Preeclampsia is associated with perinatal brain injury. Autologous placenta stem cell transplantation represents a promising future treatment option for neuroregeneration. The aim of this study was to compare the neuroregenerative capacity of preeclampsia-placenta stem cells to previously characterized placentas from uncomplicated pregnancies.

Diagnosis and treatment of iron-deficiency anaemia during pregnancy and postpartum

Iron-deficiency anaemia during pregnancy and postpartum occurs frequently and may lead to severe maternal and foetal complications. New treatment regimens include intravenous iron administration in particular clinical situations. The aim of the study was to determine optimal diagnostic and therapeutic approaches to iron-deficiency anaemia during pregnancy and postpartum.

Fertility preservation in >1,000 patients: patient's characteristics, spectrum, efficacy and risks of applied preservation techniques

Data on the characteristics of female patients counselled for fertility preservation and the efficacy and risk of the applied procedures are still poor. We therefore analysed the registry of a network of 70 infertility centers which are involved in fertility preservation in Germany, Switzerland and Austria, called FertiPROTEKT ( hhtp://www.fertiprotekt.eu ).

Homing of placenta-derived mesenchymal stem cells after perinatal intracerebral transplantation in a rat model

The aim of this study is to assess early homing of placenta-derived stem cells after perinatal intracerebral transplantation in rats.

Off-label use of misoprostol for labor induction: a nation-wide survey in Switzerland

Off-label use of drugs is frequent in obstetrical practice. No data however are available about nation-wide off-label use in obstetrics regarding frequency and patient information. The objective of our study was to assess the clinical practice of off-label use of misoprostol for labor induction.
