RESUMEN

The basic principles of proton magnetic resonance spectroscopy are presented in this work to briefly familiarize the clinician and to distinguish spectroscopy from magnetic resonance imaging. For those knowledgeable about proton magnetic resonance spectroscopy, this article will also provide the reader an update on recent technical and translational developments relevant to pediatric neurologic conditions. These developments were selected for their potential impact towards the clinical care of patients in pediatric-based practices. At this point in time, these new spectroscopic approaches are currently applied to established populations with known diseases. This information will inform our knowledge about diseases and guide therapeutic options for the future.

RESUMEN

Genital tuberculosis (GTB) is an important cause of infertility in India. Lack of an accurate diagnostic test has led to an indiscriminate use of antitubercular treatment in infertile women. Apart from concerns of drug toxicity, this may be a contributing factor in the increasing incidence of multidrug-resistant TB reported in India. We conducted a study to analyze whether a combination of tests could help improve diagnostic accuracy. An algorithm for the management of GTB in infertile women based on the use of multiple tests is presented.

RESUMEN

Oncofertility is gaining importance because of increasing cancer incidence, high survivorship, the need to provide a good quality of life to survivors and the desire of patients to preserve their fertility. Disseminating information about the effect of cancer and cancer treatment on fertility and the availability and effectiveness of fertility preservation techniques is critical. Gynaecologists in India act as family physicians and are in a unique position to guide cancer patients on issues of fertility and fertility preservation. Their contribution in oncofertility is vital to improve the quality of life of many young survivors. This paper presents the result of a survey done with Indian gynaecologists. The aim of this survey was to ascertain awareness and knowledge of reproductive damage by cancer therapy, knowledge of fertility preservation techniques and an understanding of the barriers to fertility preservation. This information would assist in planning programs to improve oncofertility care and counselling.

RESUMEN

BACKGROUND: Mature oocytes are prerequisite for achieving the process of in vitro fertilization. Human chorionic gonadotropin (hCG) is the standard trigger used for stimulating ovulation but is associated with ovarian hyperstimulation syndrome (OHSS). Gonadotropin-releasing hormone agonist trigger achieves oocyte maturation and lowers the incidence of OHSS, but it has limitations of higher pregnancy loss rate and miscarriage rates. Coadministration of both hormones is found to improve the pregnancy rates and the number of mature oocytes retrieved. We aimed to assess if the dual trigger is better than the conventional hCG in triggering oocyte maturation. METHODOLOGY: The study included 76 female patients aged 24-43 years who were randomly divided into two groups with 38 patients in each arm. The study included patients with antimullerian hormone (AMH) <4 ng/ml, antral follicle counts (AFCs)/ovary <12. The study excluded high responders-AMH >4 ng/ml and AFC/ovary >12 to avoid OHSS risk with hCG trigger. RESULTS: The study showed statistically insignificant differences between dual group versus hCG group in terms of the number of oocytes retrieved (10.0 ± 5.6 vs. 8.7 ± 5.0; P = 0.2816), the number of mature oocytes recovered (8.4 ± 5.0 vs. 7.2 ± 4.0; P = 0.2588), fertilization rate (5.9 ± 4.2 vs. 5.6 ± 3.3; P = 0.7390), and the number of usable embryos on day 3 (4.0 ± 3.0 vs. 4.0 ± 2.4; P = 0.8991). CONCLUSION: The dual trigger is equivalent to hCG in triggering oocyte maturation.

RESUMEN

Deep venous thrombosis (DVT) has been reported extensively following ovarian hyperstimulation syndrome during in-vitro fertilization (IVF). Pregnancy per se increases the risk of DVT due to a hypercoagulable state. The long-term use of hormone replacement therapy (HRT) is another critical factor associated with DVT in women. However, an association between the short-term use of HRT in oocyte donation (OD) cycles and DVT has not yet been reported. We present a case of 43-year-old woman who developed DVT after IVF-OD. DVT was diagnosed at 7 weeks of pregnancy and was managed with low-molecular-weight heparin. We suggest that even a short-term use of HRT should be considered a risk factor for DVT especially in the presence of additional risk factors such as obesity. The patient had an uneventful recovery and delivered three healthy though preterm babies.

RESUMEN

We report a case of early onset severe ovarian hyperstimulation syndrome (OHSS) presenting with oliguria in an antagonist cycle triggered with GnRH agonist and a freeze-all approach. Prophylactic measures in the form of GnRH antagonist, cabergolin and plasma expanders were given after oocyte retrieval. Twenty-four hours after oocyte retrieval patient developed oliguria and moderate ascites. She was managed in ICU with albumin and diuretics. She responded to conservative management and did not require paracentesis. Severe OHSS can occur in PCOS patients even after using a segmented approach i.e. GnRH agonist trigger with a 'freeze all' policy. Patients at risk of OHSS should be closely monitored following ovum pickup even when an agonist trigger has been given, for early detection and management.

RESUMEN

OBJECT: Sylvian arteriovenous malformations (sAVMs) are challenging lesions of the central nervous system. The natural history of these unique lesions as well as clinical outcomes following treatment of sAVMs has been limited to case series owing to the rarity of these lesions. The authors present their experience with sAVMs and review the literature. METHODS: In accordance with the Henry Ford Institutional Review Board, medical records of patients with sAVMs treated from 2000 to 2012 were reviewed. Clinical data were retrospectively collected to calculate pre- and posttreatment modified Rankin Scale scores for all patients. RESULTS: The authors identified 15 patients with sAVMs who received treatment. Of these, 12 were female and 3 were male, and the average age at presentation was 39.6 ± 12.94 years (± SD). Two patients (13.3%) had Spetzler-Martin Grade I lesions, 6 patients (40%) had Grade II lesions, 5 patients (33.3%) had Grade III lesions, and another 2 (13.3%) harbored Grade IV arteriovenous malformations (AVMs). According to the Sugita classification, 6 patients (40%) had medial lesions, 6 (40%) had lateral lesions, 2 (13.3%) had deep lesions, and 1 patient (6.67%) had a pure sAVM. Eight patients (53.3%) underwent stereotactic radiosurgery while 7 patients (46.7%) had microsurgical resection; 1 patient underwent surgical extirpation after incomplete response following radiosurgery. After treatment, 9 patients were unchanged from pretreatment (60%), 3 patients worsened, and 2 patients had improved functional outcome (20% and 13.3%, respectively). The authors' literature search yielded 348 patients with sAVMs, most of them harboring Spetzler-Martin Grade II and III lesions. Approximately 98% of the patients underwent resection with excellent outcomes. CONCLUSIONS: While the ideal choice of therapeutic modality for cerebral AVMs remains controversial in light of the recent publication of the ARUBA (A Randomized trial of Unruptured Brain AVMs) trial, a multidisciplinary treatment approach for the management of sAVMs can lead to acceptable neurological outcome.
