1/18. Successful in-vitro fertilization in a natural cycle after four previously failed attempts in stimulated cycles: case report.A case is reported of successful in-vitro fertilization (IVF) and pregnancy in a natural cycle after four previously failed attempts with stimulated cycles. The patient began treatment at the age of 36 years and underwent four stimulated IVF cycles, each time with three embryos of good quality transferred. In one attempt, three cryopreserved embryos were transferred in a natural cycle. The patient failed to conceive. At the age of 38 years, the patient was entered into a natural cycle IVF programme. The patient conceived twice in each of her first two attempts but unfortunately aborted. In her third natural cycle of IVF, again with one oocyte obtained and one embryo transferred, the patient conceived and had a full term gestation. It is concluded that IVF in a natural cycle is a viable option for infertile women with blocked fallopian tubes who have normal ovulatory menstrual cycles.- - - - - - - - - - ranking = 1keywords = embryo (Clic here for more details about this article) |
2/18. Molecular cloning of translocation breakpoints in a case of constitutional translocation t(11;22)(q23;q11) and preparation of probes for preimplantation genetic diagnosis.in vitro fertilization (IVF) centres with preimplantation genetic diagnosis (PGD) programmes are often confronted with the problem of identifying chromosomal abnormalities in interphase cells biopsied from preimplantation embryos of carriers of a reciprocal translocation. The present authors have developed a DNA testing based approach to analyse embryos from translocation carriers, and this report describes breakpoint-spanning probes to detect abnormalities in cases of the most common human translocation (i.e. the t(11;22)(q23;q11)). Screening a yeast artificial chromosome (YAC) library for probes covering the respective breakpoint regions in the patient lead to probes for the breakpoint on chromosome 11q23. The physically mapped YAC and bacterial artificial chromosome (BAC) clones from chromosome 22 were then integrated with the cytogenetic map, which allowed localization of the breakpoint on chromosome 22q11 to an interval of less than 84 kb between markers D22S184 and KI457 and to prepare probes suitable for interphase cell analysis. In summary, breakpoint localization could be accomplished in about 4 weeks with additional time needed to optimize probes for use in PGD.- - - - - - - - - - ranking = 6.401251118085keywords = preimplantation, embryo (Clic here for more details about this article) |
3/18. Early localized peritoneal mesothelioma as an incidental finding at laparoscopy. Report of a case and implications regarding natural history of the disease.BACKGROUND: Peritoneal mesothelioma is regarded as a fatal disease that presents with progressive ascites in a relatively late stage of its natural history. To the authors' knowledge, prior published articles have not described the early manifestations of this cancer. methods: A 30-year-old asymptomatic woman underwent laparoscopy for an infertility workup. Nodules noted in the pelvis were biopsied and determined to be mesothelioma. Standard immunohistochemical studies were performed. Cytoreductive surgery and heated intraoperative intraperitoneal chemotherapy were used for treatment. RESULTS: Multiple (approximately 30) tumor nodules up to 2 mm in dimension and limited to the pelvis were observed and resected. No primary tumor focus was evident. These tumor nodules stained positive for Calretinin and negative for carcinoembryonic antigen immunohistochemically. CONCLUSIONS: In this patient, no incidence for transcoelomic dissemination of mesothelioma from a single primary site was observed. Rather, this patient's clinical presentation suggested that mesothelioma may be multifocal in origin within a limited region of the peritoneal cavity. This hypothesis may support a rationale for aggressive local-regional management of selected patients in whom peritoneal mesothelioma is of limited distribution and mass.- - - - - - - - - - ranking = 0.33333333333333keywords = embryo (Clic here for more details about this article) |
4/18. pregnancy after cytoplasmic transfer in a couple suffering from idiopathic infertility: case report.Couples suffering from idiopathic infertility are among the most difficult to treat in IVF cycles due to the unknown cause of failure to reproduce. This can lead to years of unsuccessful attempts to conceive and often the abandonment of treatment. In some couples, the only observable problem is the development of poor quality embryos. In this case report, we describe the successful use of cytoplasmic donation in a couple where the high level of embryo fragmentation and poor embryo development was thought to be the unique cause of failure to conceive after intracytoplasmic sperm injection (ICSI). We noted a strong reduction in embryo fragmentation and a consequent increase in embryo quality after the treatment. Transfer of four of the embryos receiving donor cytoplasm led to a pregnancy with two gestational sacs and the birth of healthy twins.- - - - - - - - - - ranking = 2keywords = embryo (Clic here for more details about this article) |
5/18. Quadruplet pregnancy following transfer of two embryos: Case report.Following a long period of secondary unexplained infertility, a couple had assisted conception treatment with IVF and transfer of two embryos 2 days later. The woman conceived and was found to have a quadruplet pregnancy. Following spontaneous labour onset at 34 weeks gestation, she was delivered by immediate Caesarean section. All four babies (three boys, one girl) were eventually discharged home with the mother. All the boys were found to be of differing zygosity. The quadruplet pregnancy was attributed to natural conception following intercourse and fertilization of oocytes not collected at the time of IVF. The wisdom of intercourse during a cycle of IVF is discussed.- - - - - - - - - - ranking = 1.6666666666667keywords = embryo (Clic here for more details about this article) |
6/18. Preimplantation genetic diagnosis of chromosome abnormalities: implications from the outcome for couples with chromosomal rearrangements.OBJECTIVES: Chromosomal rearrangements can lead to infertility or repeated spontaneous or induced abortions. The use of preimplantation genetic diagnosis (PGD) allows the selected transfer of chromosomally balanced embryos. The aim of this study was to carry out detailed analysis of the outcome of 11 PGD cycles for 8 patients carrying various chromosomal rearrangements. methods: patients underwent routine in vitro fertilisation with biopsy of embryos on day 3. Specific fluorescent in situ hybridisation protocols were developed for each couple. embryo transfer was possible in all 11 cycles. RESULTS: The outcome was four pregnancies, leading to three live births and one biochemical pregnancy. Post-zygotic mosaicism was detected in 75% of untransferred embryos, the majority of which were chaotic. Detailed follow-up and analysis provided evidence for the co-existence of chromosomally balanced and abnormal cells in six embryos. The mechanisms involved included chromosome breakage and loss of material. CONCLUSIONS: biopsy and analysis of two blastomeres, where possible, reduced the risk of misdiagnosis in cases of balanced/aneuploid mosaics. The three live births achieved for the eight couples treated in this series, despite the poor history in almost all cases, is further proof that a policy of biopsying two cells from embryos consisting of six or more cells and a single cell from four- or five-cell embryos is compatible with a positive outcome.- - - - - - - - - - ranking = 2.9557640752364keywords = preimplantation, embryo (Clic here for more details about this article) |
7/18. Medical and psychological management of recurrent abortion, history of postneonatal death, ectopic pregnancy and infertility: successful implementation of IVF for multifactorial reproductive dysfunction. A case report.The medical and psychological treatment for a 37-year-old Caucasian G6 P1051 woman who presented for evaluation of secondary infertility and recurrent pregnancy loss is described. Although one living child had been conceived without medical assistance, that delivery preceded the present evaluation by ten years and involved a different partner. With the current husband, the patient had two miscarriages and a left ectopic pregnancy. The couple had attempted controlled ovarian hyperstimulation and in vitro fertilization (IVF) elsewhere, but the cycle was cancelled due to poor follicular response. About one year before consultation at our institution, the couple established a pregnancy although the infant was born at 24 weeks with a cardiac anomaly, living only 40 days. Additionally, a persistent cervical lesion required cone biopsy before any fertility treatment could resume. andrology evaluation found the husband's sperm dna fragmentation index to be 48.6%. This constellation of stressors represented substantial emotional issues and psychological therapy/counseling was recommended. After obtaining psychological clearance, the couple underwent IVF and 16 oocytes were retrieved. Four embryos were transferred, and a healthy male infant was delivered at term. Although multifactorial infertility can be associated with very poor reproductive outcomes, the advanced reproductive technologies merit consideration during management of complex clinical challenges. Standard IVF strategies can be optimized by inclusion of thorough psychological assessment and counseling.- - - - - - - - - - ranking = 0.33333333333333keywords = embryo (Clic here for more details about this article) |
8/18. Successful surrogate pregnancy after ovarian transposition, pelvic irradiation and hysterectomy.BACKGROUND: Treatment of cervical cancer is often effective but at the cost of the woman's fertility. Ovarian transposition with subsequent oocyte retrieval and surrogate pregnancy can enable these patients to become genetic parents. We present the third reported such case. CASE: A 22-year-old woman was diagnosed with bulky, stage IB cervical cancer. Following transposition of both ovaries to the upper abdomen, she underwent pelvic irradiation followed by total abdominal hysterectomy. Eleven years later she presented for assisted reproduction. Two oocytes were retrieved following ovarian stimulation and transcutaneous, abdominal oocyte retrieval. One embryo was transferred to the gestational surrogate, resulting in a single intrauterine pregnancy and successful delivery at term. CONCLUSION: These procedures can preservefertility while successfully treating cervical cancer.- - - - - - - - - - ranking = 0.33333333333333keywords = embryo (Clic here for more details about this article) |
9/18. Case report: delirium associated with ovarian hyperstimulation syndrome.ovarian hyperstimulation syndrome (OHSS) is one of the most important complications of assisted reproductive technologies. Mild OHSS is characterized by ovarian enlargement and abdominal discomfort. In severe cases anasarca, hepatic dysfunction, reduced blood volume, electrolyte imbalance, organ failure and thromboembolic phenomena may be observed. delirium is a syndrome, not a disease, and has many causes, all of which result in a similar pattern of signs and symptoms relating to a patient's level of consciousness and cognitive impairment. delirium remains an under-recognized and under-diagnosed clinical disorder. The case is presented of a 30-year-old woman with OHSS and delirium. She underwent intracytoplasmic sperm injection (ICSI) for severe male factor infertility. Five days after oocyte retrieval, ascite formation was observed in ultrasonographic evaluation, and embryo transfer was cancelled. Twelve days after retrieval she came to the emergency clinic with abdominal distension and pain. She was hospitalized and paracentesis was performed every other day three times. She had altered consciousness and psychomotor hypoactivity 1 h after the last paracentesis. Psychiatric consultation revealed that she was in a state of delirium, and haloperidol was administered for treatment. Her symptoms disappeared within a week. Her medication was stopped when symptoms resolved and she was still asymptomatic in psychiatric evaluation 1 week later.- - - - - - - - - - ranking = 0.33333333333333keywords = embryo (Clic here for more details about this article) |
10/18. Unusual presentation of a woman with polycystic ovaries and complex endometrial pathology.A 28-year-old woman with polycystic ovarian syndrome (PCOS) had attempted four assisted conception treatments, all of which were complicated by lack of response of the endometrium to the hypo-oestrogenic state induced with gonadotrophin releasing hormone analogue (GnRHa). Consequently, two treatment cycles were abandoned, one prior to the ovulation induction of a fresh IVF treatment and the other prior to oestrogen replacement for a frozen-thawed embryo transfer treatment cycle. Extended down-regulation eventually resulted in endometrial thinning and allowed completion of the other two treatments, but the outcome was negative. A targeted mid-cycle ultrasound scan in a natural cycle at follow-up showed thick, non-homogenous endometrium. A repeat hysteroscopy on this occasion showed abnormal endometrium with chalk-like deposits. Histological diagnosis was chronic endometritis and endometrial hyperplasia with focal atypia. Microbiological tests, including those for mycobacterium tuberculosis, were negative. Because of atypical endometrial hyperplasia, this patient is currently under close follow-up by the original referring team. This case highlights inherent endometrial pathology presenting as non-responding endometrium to hormonal down-regulation, the limitations of conventional ultrasound scans, and the complimentary role of concomitant hysteroscopy in the correct identification of endometrial lesions that may negatively affect the assisted conception treatments.- - - - - - - - - - ranking = 0.33333333333333keywords = embryo (Clic here for more details about this article) |
