Immune-mediated encephalitis and virilization in association with a mature cystic ovarian teratoma in an adolescent girl.

BACKGROUND: Mature cystic teratomas are the most common form of ovarian tumor in children and adolescents. These tumors are mostly benign and non-secreting. Virilization from an ovarian teratoma is exceptionally rare in pediatrics. Equally rare is the association of ovarian teratomas with auto-immune encephalitis. METHODS: We describe the case of a 15-year-old girl with menstrual abnormalities and virilization, who had a past medical history of encephalitis of an unknown etiology 16 months prior to presentation. RESULTS: Endocrine evaluation revealed an elevated serum testosterone and 17-hydroxy progesterone. A large left ovarian tumor was seen on a CT scan. Surgical excision revealed a mature cystic teratoma containing 6 liters of clear fluid with high androgen levels. Antibodies to the N-methyl-D-aspartate receptor of the hippocampus were detected in pre-operatively archived serum, but undetectable 6 months postoperatively. Immunohistochemistry studies on the tumor sections revealed that the antibodies in the patient's serum reacted with areas of the tumor expressing the N-methyl-D-aspartate receptor. Postoperatively, the patient's menstrual cycles became regular and her behavioral problems resolved. Her testosterone levels fell precipitously as well. CONCLUSION: Both virilizing mature cystic teratomas and teratoma-associated encephalitis are extremely rare in the pediatric population. We report on the first instance of these 2 rare entities occurring in the same patient.

Novel Inactivating Mutation of the FSH Receptor in Two Siblings of Indian Origin With Premature Ovarian Failure.

CONTEXT: Inactivating FSH receptor (FSHR) mutations can affect ovarian function, resulting in variable clinical presentations ranging from primary amenorrhea to premature menopause. FSHR mutations have been largely reported in the Finnish population, but in patients of Asian Indian descent, the incidence of FSHR mutations is extremely rare. CASE DESCRIPTION: Two female siblings of Indian descent were diagnosed with primary ovarian failure and hypergonadotropic hypogonadism. The daughters were the result of a consanguineous marriage between second cousins. A combination of comparative genomic hybridization plus single nucleotide polymorphism array and whole exome sequencing was conducted on the family to identify potential causative genetic variants. CONCLUSION: Both daughters were found to have a novel pathogenic variant in FSHR (c.1253T>G, p.Ile418Ser), inherited as an autosomal recessive trait from heterozygous parents. This loss of function mutation is located in exon 10 of FSHR affecting the second transmembrane helix of the FSHR protein. The transmembrane domain of FSHR is highly conserved across species and is involved in signal transduction. The FSHR c.1253T>G variant is next to a known pathogenic variant, rs12190966 (c.1255G>A, p.Ala419Thr), previously reported in a Finnish woman with primary amenorrhea.

Attitude to family planning in an Aurangabad slum.

PIP: The impact of efforts by the Medical College Hospital and the Regional Family Planning Training Centre in Aurangabad, India, to popularize family planning in the city's slum areas was assessed through a KAP survey conducted by medical interns, social workers, and other hospital staff. In all, 237 couples were surveyed. Of these, 156 were Nav Buddhas, 53 were Hindus, 17 were Christians and 11 were Muslims. When asked if they were aware of birth control, 108 replied in the affirmative (the "Aware" group) and 129 were ignorant (the "Unaware" group). Only 21 from the "Aware" group were practicing a family planning method. Of the 21 acceptors, there were 15 vasectomies, 3 tubectomies, and in 3 cases, use of the condom by the husband. The most common reason for failure to practice contraception was the desire for more children, although many felt that contraception was unnecessary or they had neglected to think about family limitation. It is important that only 33 out of 237 (14%) recognized the widely publicized symbol for family planning (inverted red triangle); and the proportion of contraception acceptors in this group was significantly more than among those who failed to recognize the symbol. Survey findings indicated that efforts to reach the population in the ever-increasing slums in urban areas must be intensified.^ieng

Differential gene expression between visceral and subcutaneous fat depots.

Abdominal obesity has been linked to the development of insulin resistance and Type 2 diabetes mellitus (DM2). By surgical removal of visceral fat (VF) in a variety of rodent models, we prevented insulin resistance and glucose intolerance, establishing a cause-effect relationship between VF and the metabolic syndrome. To characterize the biological differences between visceral and peripheral fat depots, we obtained perirenal visceral (VF) and subcutaneous (SC) fat from 5 young rats. We extracted mRNA from the fat tissue and performed gene array hybridization using Affymetrix technology with a platform containing 9 000 genes. Out of the 1 660 genes that were expressed in fat tissue, 297 (17.9 %) genes show a two-fold or higher difference in their expression between the two tissues. We present the 20 genes whose expression is higher in VF fat (by 3 - 7 fold) and the 20 genes whose expression is higher in SC fat (by 3 - 150 fold), many of which are predominantly involved in glucose homeostasis, insulin action, and lipid metabolism. We confirmed the findings of gene array expression and quantified the changes in expression in VF of genes involved in insulin resistance (PPARgamma leptin) and its syndrome (angiotensinogen and plasminogen activating inhibitor-1, PAI-1) by real-time PCR (qRT-PCR) technology. Finally, we demonstrated increased expression of resistin in VF by around 12-fold and adiponectin by around 4-fold, peptides that were not part of the gene expression platform. These results indicate that visceral fat and subcutaneous fat are biologically distinct.
