    In childhood mature cystic teratomas are the most common type of ovarian germ cell tumors. Tumors of neuroepithelial origin are extremely rare in mature teratomas. To the authors' knowledge, this is the first case report oligodendroglioma arising in a mature cystic ovarian teratoma in children. A 13-year-old girl presented with a history of pelvic pain for 2 months. An ultrasound examination showed a monolateral multicystic, calcific ovarian mass, measuring approximately 6 x 5 cm, arising in the left over and adnexia, suggesting a teratoma. An exploratorative laparotomy and ooferectomy were performed. On histopatological examination, various samples from cystic areas had mature tissues from all 3 germ cell layers, including skin, bone, bronchial structures, and cerebellum. Sections from solid areas showed uniform population of monotonous, rounded cells with indistinct cytoplasm and having perinuclear halo (fried-egg appearance) on a fibrillary, neuropilic background. Microcalcifications as calcospherites were noted in the stroma. Based on the typical morphological features, the cased was diagnosed as mature cystic teratoma with low-grade oligodendroglioma. To the authors' knowledge, there are a few reports in the literature of an oligodendroglioma arising in an ovarian teratoma in adults and this presented patient is the first case in childhood.

  2. Primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma: A case report

    Nicolas M. Orsi


    Full Text Available Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses. Features of a mature cystic teratoma were seen very focally. Immunohistochemistry revealed strong, diffuse positivity for CD56 and synaptophysin. Chromogranin immunonegativity was noted and there was an absence of nuclear β-catenin accumulation. Ki-67 index was 10–12%. Although there is no established diagnostic framework for primary ovarian carcinoid tumors, this case was diagnosed as a well-differentiated neuroendocrine tumor, Grade 2 (intermediate grade, arising in association with a mature cystic teratoma/dermoid cyst. This case highlights the need to develop ovarian diagnostic criteria in this area.

  3. Rupture of Ovarian Mature Cystic Teratoma: Computerized Tomography Findings; Rotura de teratoma quistico madure de ovario: hallazgos por tomografia computerizada

    Sebastia, C.; Sarrias, M.; Sanchez-Aliaga, E.; Quiroga, S.; Boye, R.; Alvarez-Castells, A. [Hospital General Universitari Vall d' Hebron. Barcelona (Spain)


    We present computed tomography findings of three cases of intraperitoneal rupture of ovarian mature cystic teratoma. Acute-phase radiological findings include presence of intraabdominal liquid, infiltration of mesenteric fat and calcified pelvic mass which also showed interior fatty content. Chronic-phase findings include infiltration of peritoneal fat, as well as increase in the size of adjacent ganglion due to chronic inflammatory response to histologically verified foreign bodies. Differential diagnoses between chronic and acute intraperitoneal ruptures of mature teratoma have been reviewed. (Author)

  4. Successful Laparoscopic Resection of 7 mm Ovarian Mature Cystic Teratoma Associated with Anti-NMDAR Encephalitis

    Masaru Hayashi


    Full Text Available Anti-NMDAR (N-methyl-D-aspartate receptor encephalitis is an immune-mediated encephalitis. It has been predominantly described in young women and is commonly associated with an ovarian teratoma. We report a case of anti-NMDAR encephalitis associated with a 7 mm ovarian teratoma that was completely resected by laparoscopic surgery. An 18-year-old woman suddenly presented with personality changes requiring her admission to the department of neurology. After that, she also showed involuntary movements, disturbance of consciousness, and central hypoventilation. As an abdominal image revealed the possibility of a right ovarian teratoma of 5×7 mm, a laparoscopic operation was performed. The macroscopic appearance of the right ovary did not show any abnormalities; nevertheless, we performed a partial resection of the right ovary, with reference to the image diagnosis, in order to spare the ovarian reserve. The 22×22 mm partially resected ovary contained an intact 5×7 mm cystic tumor. The pathological diagnosis was mature cystic teratoma with components of brain tissue. An anti-NMDAR-antibody test proved positive in both serum and cerebrospinal fluid 1 month after the surgery. From these results, she was diagnosed with anti-NMDAR encephalitis. By the administration of cyclophosphamide in addition to the operation, she recovered drastically without any of the symptoms shown before.

  5. The presence of centrioles and centrosomes in ovarian mature cystic teratoma cells suggests human parthenotes developed in vitro can differentiate into mature cells without a sperm centriole

    Lee, Bo Yon, E-mail: [Department of Obstetrics and Gynecology, Kyung Hee University Hospital, Kyung Hee University, School of Medicine, Seoul (Korea, Republic of); Shim, Sang Woo; Kim, Young Sun; Kim, Seung Bo [Department of Obstetrics and Gynecology, Kyung Hee University Hospital, Kyung Hee University, School of Medicine, Seoul (Korea, Republic of)


    Highlights: Black-Right-Pointing-Pointer The sperm centriole is the progenitor of centrosomes in all somatic cells. Black-Right-Pointing-Pointer Centrioles and centrosomes exist in parthenogenetic ovarian teratoma cells. Black-Right-Pointing-Pointer Without a sperm centriole, parthenogenetic oocytes produce centrioles and centrosomes. Black-Right-Pointing-Pointer Parthenogenetic human oocytes can develop and differentiate into mature cells. -- Abstract: In most animals, somatic cell centrosomes are inherited from the centriole of the fertilizing spermatozoa. The oocyte centriole degenerates during oogenesis, and completely disappears in metaphase II. Therefore, the embryos generated by in vitro parthenogenesis are supposed to develop without any centrioles. Exceptional acentriolar and/or acentrosomal developments are possible in mice and in some experimental cells; however, in most animals, the full developmental potential of parthenogenetic cells in vitro and the fate of their centrioles/centrosomes are not clearly understood. To predict the future of in vitro human parthenogenesis, we explored the centrioles/centrosomes in ovarian mature cystic teratoma cells by immunofluorescent staining and transmission electron microscopy. We confirmed the presence of centrioles and centrosomes in these well-known parthenogenetic ovarian tumor cells. Our findings clearly demonstrate that, even without a sperm centriole, parthenotes that develop from activated oocytes can produce their own centrioles/centrosomes, and can even develop into the well-differentiated mature tissue.

  6. Ependymoma and Carcinoid Tumor Associated with Ovarian Mature Cystic Teratoma in a Patient with Multiple Endocrine Neoplasia I

    Reed Spaulding


    Full Text Available Ovarian teratomas rarely undergo new neoplastic transformation and account for a small percentage of malignant ovarian germ cell neoplasms. Here we report a case of a 51-year-old woman with multiple endocrine neoplasia type I (MEN I who was found to have an ependymoma and neuroendocrine tumor (trabecular carcinoid associated with mature cystic teratoma of her left ovary. The ependymoma component displayed cells with round nuclei and occasional small nucleoli which were focally arranged in perivascular pseudorosettes and true rosettes. Rare mitoses were identified. No necrosis was present. Immunohistochemical staining was positive for S-100 and GFAP. The Ki67 proliferation index was very low (2-3%. In contrast, the endocrine tumor component was composed of small uniform cells with eosinophilic cytoplasm, round nuclei, and speckled chromatin. Immunohistochemical staining was positive for synaptophysin and focally positive for chromogranin. This rare case illustrates that MEN I may have an influence on the pathogenesis of ovarian teratomas as they undergo malignant transformation.

    Ozkaya, Mesut; Sayiner, Zeynel Abidin; Kiran, Gurkan; Gul, Kamile; Erkutlu, Ibrahim; Elboga, Umut


    Acromegaly is a clinical syndrome caused by the overproduction of growth hormone (GH) and also known as a rare disease. Clinical, biochemical, and radiological features are often indistinguishable between GH-producing hypophysis adenomas and ectopic GH-releasing hormone (GHRH)-producing tumors. A 40-year-old woman presented to us with her growing feet, hands especially fingers, and enlarging nose. Biochemical diagnosis of acromegaly was made by measuring insulin-like growth factor-1 (IGF-1) level and glucose-suppressed GH estimation. Her spot IGF-1 level was 1300 ng/ml (90-226 ng/ml). The basal GH was 30 ng/l, and 60- and 120-min GH levels after 75-g oral glucose load were 29 and 40 ng/l, respectively. Magnetic resonance imaging (MRI) of pituitary was normal. There was no pituitary adenoma or pituitary hyperplasia. Extrapituitary ectopic hypersecretion of GH or GHRH-secreting tumor search was done by high-resolution computed tomography (CT) of chest and whole abdomen. Abdomen CT revealed 9.5 × 8 cm pelvic mass, which included calcific regions and solid component. The specimen's immunohistochemical staining with GH was positive but interestingly GHRH was negative. According to immunohistochemical staining, the patient's diagnosis was ectopic acromegaly due to a GH-secreting neuroendocrine-differentiated tumor developed from an ovarian mature cystic teratoma. Herein, we present excellent illustration of an unusual and confusing clinical scenario of ectopic acromegaly.

  8. Huge Benign Ovarian Cystic Teratoma in a Patient with a History of Hansen's Disease.

    Okonta, Patrick I; Mofon, Chukwuemeke


    Mature ovarian cystic teratomas are common benign ovarian neoplasm derived from germ cells. With increasing availability of ultrasound services even in developing countries, the diagnosis of benign ovarian tumour is made earlier and the size of the ovarian tumour at diagnosis is relatively small. It is unusual to find an ovarian cystic teratoma larger than 10 cm. We report a huge mature ovarian cystic teratoma in a multipara with a history of Hansen's disease. We conclude that, in circumstances where women have restricted access to health care, the unusual finding of mature ovarian cystic teratoma larger than 10 cm is possible due to delayed presentation for diagnosis and treatment.

  9. Oligodendroglial cell proliferation arising in an ovarian mature cystic teratoma. Clinicopathological, inmunohistochemical, and ultrastructural study of a case that may represent an oligodendroglioma.

    Serrano-Arévalo, Mónica Lizzette; Lino-Silva, Leonardo Saúl; Domínguez Malagón, Hugo Ricardo


    Ovarian mature cystic teratoma (OMCT) is an ovarian benign neoplasm with excellent prognosis presenting components of the three germinal layers. However, transformation into a malignant neoplasm is a rare event (so-called somatic transformation). In most of the cases, the malignant component expresses as epidermoid carcinoma, but occasionally central nervous system tumors occur. Some of the previously reported tumors are astrocytoma, glioblastoma, and ependymoma. Somatic transformation of OMCT into an oligodendroglioma is exceptional. We report a 19-year-old female with a left OMCT with an area of oligonedroglial cells proliferation characterized by immunohistochemical studies with positivity for GFAP and S100, with a low Ki67 index (5%). Additionally, electron microscopy revealed oligodendrocytes with parallel bundles of cytoplasmic intermediate filaments, confirming the oligodendroglial nature of the proliferation. The patient was treated only with left oophorectomy, and three and half years after surgery, there is no evidence of disease.

  10. Mature ovarian teratoma with large floating fat globules

    Son, Hye Min; Kim, See Hyung; Hwang, Il Seon [Keimyung University School of Medicine, Dongsan Medical Center, Daegu (Korea, Republic of)


    Mature ovarian teratoma (dermoid cyst), a germ cell neoplasm, is one of the most common ovarian tumors. It is composed of derivatives of three germ cell layers. A mature ovarian teratoma with intracystic fat globules is rare. The pathogenesis on the formation of fat globules is unclear. Here we present a pathologically proven cystic ovarian teratoma with three large floating fat globules in a young woman with CT and MR findings.

  11. Rare Skin Adnexal and Melanocytic Tumors Arising in Ovarian Mature Cystic Teratomas: A Report of 3 Cases and Review of the Literature.

    Moulla, Alexandra A; Magdy, Nesreen; Francis, Nicholas; Taube, Janis; Ronnett, Brigitte M; El-Bahrawy, Mona


    Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

  12. Malignant Transformation of a Mature Cystic Ovarian Teratoma into Thyroid Carcinoma, Mucinous Adenocarcinoma, and Strumal Carcinoid: A Case Report and Literature Review

    Hilary D. Hinshaw


    Full Text Available Malignant transformation of a mature cystic teratoma (MCT is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a, mucinous adenocarcinoma (b, and strumal carcinoid tumor (c—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a. Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b. Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c.

  13. Enhancing Solid Component within Mature Ovarian Teratomas on MR: Does it Indicate a Malignant Transformation?

    Song, Myung Gyu; Kim, Kyeong Ah; Lee, Chang Hee; Choi, Jae Woong; Lee, Jong Mee; Kim, Yun Hwan; Park, Cheol Min [Korea University Guro Hospital, Seoul (Korea, Republic of)


    To evaluate the enhancing solid component within mature ovarian teratomas on pelvic MR examinations. Thirty-two women with surgically proven mature cystic teratomas underwent preoperative pelvic MR examinations. Five cases had an enhancing solid component within mature cystic ovarian teratomas on MR images. The MR images were retrospectively analyzed by two radiologists by consensus, focusing on the enhancing portion of tumor and the tumor itself. The study subjects include 5 patients (15.6%) with enhancing solid components within the mature ovarian cystic teratomas. The mean tumor size was 9.8 cm and they were all unilateral. The enhancing solid components of the tumors had a variable appearance and were located in the peripheral region. No cases were found to have a transmural extension or direct invasion of the neighboring pelvic organ. An enhancing solid component associated with mature ovarian teratomas is not uncommon. This finding does not however, necessarily indicate malignant transformation.




    Full Text Available Germ cell tumors account for a majority of all ovarian tumors. Ninety five percent of germ cell tumors are dermoid cysts (Mature cystic teratoma. Carcinomas arising from mature cystic teratoma are quite rare. The most common malignancy being Squamous cell carcinoma (75%. In the present study we report a case of Squamous cell carcinoma arising in a mature cystic teratoma. A 45 year old female presented with mass in abdomen, pain abdomen and dysuria since one month. Total abdominal hysterectomy with bilateral salpingo-opherectomy was done. Histopathology showed well differentiated invasive squamous cell carcinoma arising in the background of mature cystic teratoma (dermoid cyst. Purpose of this report was to create awareness among practitioners to consider this possibility in dermoid cysts of large size in older patients

  15. Ovarian Mature and Immature Teratomas in Monozygotic Twins: A Case Report of Simultaneous Presentation

    Kawai, Naoki; Takeshita, Toshiyuki


    Mature cystic teratoma is one of the most common kinds of ovarian tumor, and immature teratoma is a rare tumor, representing less than 1% of all ovarian teratomas. Although there are some reports about familial occurrences of ovarian tumors, literature concerning the clinical cases of monozygotic twins is rare. We report the 5-year clinical courses of a 12-year-old Japanese girl with a recurrent bilateral ovarian mature teratoma and her monozygotic twin with a unilateral ovarian mature teratoma and contralateral ovarian immature teratoma. This is the first clinical report on mature and immature teratomas of the ovary in monozygotic twins. Our cases support future clarification of the molecular mechanism and pathogenesis of teratoma.

  19. Minimal laparotomy management of a giant ovarian cystic teratoma in adolescence

    Toshihiro Yasui


    Full Text Available Giant ovarian cysts in adolescents are very rare. Those treatment by laparotomy or laparoscopic surgery is discussed with gynecologists and pediatric surgeons because its limited working space and risk of rupture and malignancy. We present a case of minimal laparotomy management of a giant ovarian cystic teratoma in adolescent. A 13-year-old girl presented with abdominal pain and constipation. A CT scan showed a giant simple ovarian cystic tumor in her abdomen measuring 29 × 13 × 24 cm. We made a 3-cm Pfannenstiel incision and inserted an Alexis wound retractor XS. The cyst was completely aspirated without spillage in the intraperitoneal space. In total, 6L of murky brown fluid was aspirated from the cyst. There was no ovarian tissue visible on the cyst wall. The left tube and right ovary and tube were intact. The cyst wall and left ovary tube were dissected free by using a LigaSure. Postoperative recovery was uneventful. Pathological assessment revealed a mature cystic teratoma. The ovarian tissue was included in the part of the cyst wall. We were able to safely perform with minimal laparotomy. Therefore, we consider the for cases of giant ovarian tumors, minimal laparotomy surgery is useful from the safety and cosmetic perspective.

  20. Ovarian mucinous cystic tumor of borderline malignancy with a mural nodule of anaplastic spindle cell carcinoma: a case report.

    Yamazaki, Hitoshi; Matsuzawa, Akiyo; Shoda, Takashi; Iguchi, Hiroyoshi; Kyushima, Noriyuki


    Ovarian cystic tumors with a mural nodule are a rare entity. We report a case of a mural nodule of anaplastic spindle cell carcinoma in an ovarian mucinous cystic tumor of borderline malignancy. The patient was a 45-years-old Japanese woman who presented with an ovarian cyst. She suffered from mature cystic teratoma of both ovaries 9 years before the present history. Image analysis and laboratory data showing a high serum CA19-9 level suggested ovarian malignancy. She underwent bilateral salpingo-oophorectomy with hysterectomy and omentectomy. There was a mural nodule in the ovarian mucinous cystic lesion. Microscopically, the nodule was composed of spindle-shaped cells with severe nuclear atypia. Immunohistochemical analysis allowed the cells to be categorized as anaplastic spindle cell carcinoma. Fifteen months after the operation the patient is alive without any clinical findings of tumor recurrence. To the best of our knowledge in the English literature, this is the first report of a mural nodule of an anaplastic spindle cell carcinoma within an ovarian mucinous cystic borderline tumor harboring previously confirmed cystic teratoma.

  1. Hashimoto's Disease in a Bilateral Benign Cystic Ovarian Teratoma: A Case Report

    Rupinderjeet KAUR


    Full Text Available A wide array of tissues derived from all the three germinal layers is seen in ovarian teratomas. Among these, thyroid tissue is present in 10% cases of all mature cystic teratomas.We report this case of Hashimoto's thyroiditis in a clinically euthyroid patient who tested positive for antithyroid peroxidase antibodies in spite of normal thyroid hormone profile.While the histological features of several disorders of thyroid tissue may be discovered, Hashimoto's thyroiditis is extremely rare finding in ovarian teratomas.

  2. Mutations of the KIT gene and loss of heterozygosity of the PTEN region in a primary malignant melanoma arising from a mature cystic teratoma of the ovary.

    Tate, Genshu; Tajiri, Takuma; Suzuki, Takao; Mitsuya, Toshiyuki


    A tumor suppressor gene at 10q23.3, designated PTEN, encoding a dual-specificity phosphatase with lipid and protein phosphatase activity, has been shown to play a pivotal role in the pathogenesis of a variety of human cancers. A frequent loss of heterozygosity (LOH) at 10q is found in melanoma; however, little is known about the role of PTEN in the pathogenesis of a primary malignant melanoma derived from ovarian mature cystic teratoma, which is an extremely rare melanoma. This study examined the genetic alterations involved in the mitogen-activated protein kinase and phosphatidylinositol 3 kinase pathways in an ovarian malignant melanoma. A LOH analysis revealed hemizygous deletion around and in the PTEN gene not only in the ovarian melanoma but also in a mature cystic teratoma. Another case of ovarian mature cystic teratomas in the absence of melanoma also showed allelic loss of the PTEN region. To date, mutations of BRAF, NRAS, and KIT genes have been reported in malignant melanomas. In the present study, D816H and K558E mutations of the KIT gene were revealed in the melanoma arising from a mature cystic teratoma, but not in a mature cystic teratoma. No mutations of the BRAF and NRAS genes were found in the melanoma. These results indicate that LOH of the PTEN region is one of the molecular alterations of an ovarian mature cystic teratoma and a KIT mutation is an additional promotional event associated with the oncogenesis of a melanoma arising from an ovarian mature cystic teratoma.

  3. An update on cystic ovarian degeneration in cattle.

    Peter, A T


    Cystic ovarian degeneration (COD) is considered to be one of the most important causes of reproductive failure in cattle. There is a severe economic loss to dairy industry because COD increases days-open in the postpartum period and the culling rates. The disease process is a consequence of a mature follicle that fails to ovulate at the appointed time of ovulation in the oestrous cycle. This anovulatory follicular structure either regresses or persists as a follicular or luteal cyst depending upon its structural/functional characteristics. The cells lining the follicular cyst synthesize oestrogen that, in certain instances, forces the animal to exhibit clinical signs of nymphomania. Besides oestrogen production, as per recent findings, they are also capable of secreting varying amount of progesterone which may dictate their fate. The animals that carry a luteal cyst may tend to be in anoestrus as the higher amount of progesterone secreted by this luteinized structure may change the pattern of gonadotrophins' secretion. Present findings suggest that perturbation of the hypothalamo-hypophyseal-ovarian (HHO) axis, due to many exogenous and endogenous factors, as the cause for anovulation. For example, it has been suggested that lack of hypothalamic or hypophyseal response to the positive feedback effect of oestrogens that are secreted by the dominant follicle as one of the many causes. The non-physiological changes that occur in the receptor expression of the HHO axis for the hormones involved in maturation, deviation, dominance and ovulation of the follicle may be yet another cause. The changes that occur at the cellular and molecular level in the ovary (in response to the factors mentioned above) that contribute to anovulation remain to be documented. This approach would allow us to completely understand the disease process. Hitherto, hormonal preparations that release luteinizing hormone from the anterior pituitary or have luteinizing hormone-like action are used

  4. Mature Ovarian Teratoma with Carcinoid Tumor in a 28-Year-Old Patient

    Stamatios Petousis


    Full Text Available Introduction. Coexistence of carcinoid tumor inside a mature cystic teratoma is an extremely rare phenomenon, especially in young women. We present the case of a 28-year-old woman diagnosed with a right ovarian carcinoid and treated uneventfully with conservative surgical approach. Case Report. A 28-year-old woman, gravid 0, parity 0, presented to our department for her annual gynecological examination and Pap smear test. During her examination, a mobile cystic mass was detected in the right lower abdomen. Ultrasound indicated a right ovarian mass 10.5 × 6.3 cm, confirmed by CT scan. Further investigation revealed AFP levels (1539 ng/mL. The ovarian mass was excised by laparoscopy, leaving intact the remaining right ovary. Frozen sections showed a mature cystic teratoma. However, paraffin sections revealed the presence of a small carcinoid within the teratoma’s gastric-type mucosa. The patient was set to a close followup. Nine months postoperatively, ultrasound pelvis imaging and CT scan of the abdomen as well as serum tumor markers have shown no evidence of recurrence disease. Conclusion. Despite the weak evidence, fertility spare surgical approach for women wanting to preserve their genital tract might be a reasonable option.

  5. Mature cystic teratoma with malignant transformation of teratomatous urothelial cells: Rare case presentation

    Senjuti Dasgupta


    Full Text Available The occurrence of malignancies in somatic elements of mature cystic teratoma of ovary is rare. The malignancies that may be encountered in dermoid cyst include squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, melanoma, sarcoma, carcinoid, and germ cell neoplasms. The development of transitional cell carcinoma (TCC in dermoid cyst is extremely rare with only four such cases having been reported in literature so far. Here we report the fifth case of such an occurrence in a 50-year-old postmenopausal multiparous female patient. She presented with pain and gradual swelling of abdomen for 1 month. Abdominal computed tomography revealed a solid space occupying lesion with few cystic components at right pelvis, raising the possibility of an ovarian neoplasm. The level of CA-125 was slightly raised (56∙45 U/ml. Total abdominal hysterectomy and bilateral salpingo-oopherectomy was performed. Microscopic examination showed cyst wall lined by stratified squamous epithelium. Beneath the cyst wall, a tumor mass was present, histological features of which resembled that of high-grade TCC (stage pT1aNXMX. On immunohistochemical analysis, the tumor was found to be positive for CK7 and CK20 and negative for WT-1. These results were consistent with a diagnosis of TCC arising in urothelium of mature cystic teratoma. Reporting of such extremely rare cases is important for the assessment of prognostic factors and treatment protocols.

  6. Squamous Cell Carcinoma Arising in a Mature Cystic Teratoma

    Suna Avcı


    Full Text Available Introduction. Malignant transformation in a mature cystic teratoma of the ovary is a rare complication. Squamous cell carcinoma is the most common transformation. We describe a new case of squamous cell carcinoma arising in a mature cystic teratoma. Case Report. A premenopausal 52-year-old female patient is diagnosed with vaginal bleeding. According to examination made on the women and the pelvic scanning, 7 cm mass is found on the right adnexa of the patient. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic lymph node dissection, and debulking were the treatments completed on the patient. According to histopathological diagnosis, squamous cell carcinoma arising in a mature cystic teratoma is diagnosed as a reason for the mass in the right adnexa of the patient. Conclusion. The prognosis of the malign transformation of MCT depends on surgery stage; however it is extremely poor. The patient should receive chemotherapy regardless of stage. We have decided to administer second cycle carboplatin and paclitaxel treatments on the patient.

  7. Concomitance of primary insular carcinoid developing in mature cystic teratoma of the ovary and endometrial papillary serous carcinoma

    Ayten LİVAOĞLU


    Full Text Available The primary ovarian carcinoid tumor is rare and must be differentiated from metastatic carcinoid tumors. Uterine serous papillary carcinoma is a highly aggressive type of endometrial carcinoma. A 70 year old patient referred to the clinic with the complaint of postmenapousal bleeding. Endometrial biopsy was performed and papillary serous carcinoma was diagnosed. Total hysterectomy and bilateral salpingoopherectomy was performed. Beside the tumor in the uterine cavity, the left ovary was 6x4,5x4 cm in size and had a multiloculated cystic appearance with a mural nodule 1,5 cm in diameter. With histopathologic examination, concomitance of insular carcinoid tumor developing in ovarian mature cystic teratoma and endometrial papillary serous carcinoma was found to be interesting and presented.

  8. Bovine cystic ovarian disease: hereditary relationships and case study.

    Kirk, J H; Huffman, E M; Lane, M


    Cystic ovarian disease (COD) was studied in a closed 300-cow dairy herd, using Dairy Herd Improvement Association and individual health records for a 7-year period (1974-1980). There were 2,112 calvings by 649 cows during the period. Cysts were found in 130 cows. Of the 649 cows that calved, 110 (16.9%) produced at least 1 daughter in which COD developed. Two bulls sired 17.6% of the daughters with COD, which was more than anticipated inasmuch as they sired only 11.6% of all daughters (P less than 0.05). These bulls were removed from the breeding program in an attempt to reduce code in the herd.

  9. Delivery Induced Intraperitoneal Rupture of a Cystic Ovarian Teratoma and Associated Chronic Chemical Peritonitis

    Reine Nader


    Full Text Available Intraperitoneal rupture of cystic ovarian teratoma is a rare complication. We report a case in a 29-year-old female, with increased abdominal circumference 2 months after vaginal delivery. MRI/CT raised this diagnosis associated to chemical peritonitis. A malignant ovarian mass with peritoneal carcinomatosis was excluded. Laparoscopic oophorectomy was performed and histologic analysis confirmed imaging findings. This case demonstrates the interest of imaging before surgery in pelvic masses to avoid misdiagnosing and to provide adequate treatment.

  10. Rare case of deep pelvic retroperitoneal mature cystic teratoma

    Shalini Mahana Valecha


    Full Text Available Mature cystic retroperitoneal teratomas are typically rare childhood tumours. Less than 20% of these occur in adults more than 30 yrs of age. Our adult patient presented with such a tumour, which had grown to a disproportionately large extent. It was deeply embedded in the true pelvis extending laterally to the pelvic wall and inferiorly till the ischiorectal fossa and was adherent to the surrounding structures displacing all. A provisional diagnosis was made after MRI scan and patient was posted for exploratory laparotomy. After extensive blunt and sharp dissection, the cyst wall could be separated from the surrounding structures and successfully excised. Histopathology confirmed the diagnosis. Being such a rare tumour, it is essential to have a high degree of suspicion in such cases that can be supported by advanced imaging modality. Early diagnosis and complete surgical removal are the mainstay of management that provide an excellent prognosis for such patients. [Int J Reprod Contracept Obstet Gynecol 2013; 2(3.000: 460-462

    Zavras, Nick; Christianakis, E; Ereikat, K; Mpourikas, D; Velaoras, K; Alexandrou, J


    The abdominal compartment syndrome (ACS) is a potentially fatal entity that occurs as a result of an acute increase in intra-abdominal pressure (IAP). The authors report on a girl with a giant ovarian cystic mass, and clinical signs of ACS and intracranial hypertension (ΙΗ). The possible mechanism of IH secondary to ACS is discussed.

  12. Ruptured mature cystic teratoma in the posterior mediastinum: A case report

    Jun, Jae Sup; Kim, Hyo Lim [Dept. of Radiology, Yeouido St. Mary' s Hospital, The Catholic University of Korea College of Medicine, Seoul (Korea, Republic of); Park, Hyun Jin; You, Jin Young; Cho, Deog Gon [St. Vincent Hospital, The Catholic University of Korea College of Medicine, Suwon (Korea, Republic of); Kim, Hyo Lim [Dept. of Radiology, Incheon St. Mary' s Hospital, The Catholic University of Korea College of Medicine, Incheon (Korea, Republic of)


    Mature teratomas are rarely located in the posterior mediastinum, and most mature teratomas are asymptomatic. Teratoma rupture into the adjacent lung and esophagus is possible but considering the rare entity of posterior mediastinal teratomas and the perforation rate, it is extremely unusual. We report a case of ruptured mature cystic teratoma located in the posterior mediastinum, showing fistula formation to the adjacent lung and esophagus, which presented with hemoptysis.

  13. Unexpected Malignant Diagnosis in Colonic Biopsies: Malignant Transformation of Ovarian Mature Teratomas—Two Case Reports and Review of the Literature

    Claudia P. Rojas


    Full Text Available Colorectal adenocarcinoma is the second cause of cancer-related deaths in the United States. The occurrence of squamous cell carcinoma in the colorectum is extremely unusual. Malignant transformation from mature cystic teratoma of the ovary is a rare event. The most common transformation is squamous cell carcinoma, followed by adenocarcinoma. It occurs more often in elderly patients, who usually present with advance disease. We report two unusual cases of postmenopausal women diagnosed with squamous cell carcinoma in colon biopsies. After surgical resections, the carcinoma was proven to be the result of malignant transformation of ovarian mature cystic teratomas. Since squamous cell carcinoma of the colorectum is extremely rare, the presence of squamous cell carcinoma in a colonic biopsy in a female patient should alert the clinicians to other possible primary sites, as seen in these cases.

    Full Text Available Teratomas are the most common germ cell tumors among pediatric and female patients, which originates from germ cells layers and can be located everywhere in bodies. They are diagnosed by ultrasonography (US, which was characterized by calcification and cystic anechoic view. Our aim is to attract attention to a 21-year-old female patient with complaint of acute abdominal pain diagnosed with teratoma by early radiological imaging. The female patient admitted to the emergency department with a new onset of abdominal pain at the lower and left sides of the abdomen for a week. The suprapubic and left costovertebral angle tenderness were found in her physical examination. We firstly chose US for imaging. The US of the abdomen showed multiple cystic masses around uterus. Heterogeneous cystic and calcified lesions were detected on the patients computerized tomography scan, and considered as teratoma. A laparotomy was performed by gynecologists. At laparotomy, lobulated cystic masses were removed and the left ovary had been detorsioned. She has been discharged after two days of postoperative observation. For patients of young females with abdominal pain such as rare gynecological diseases, teratoma and ovarian torsion, in the emergency department should be considered and early imaging should be performed.

    Hooijer, G.A.; Oijen, van M.A.A.J.; Frankena, K.; Noordhuizen, J.P.T.M.


    The aim of this field study was to investigate whether the incidence of cystic ovarian disease (COD) in dairy cows was related to milk production parameters (milk yield, milk fat and protein) in early lactation with special emphasis on the negative energy balance (NEB). The diagnosis of COD was made

  17. A Huge Ovarian Dermoid Cyst: Successful Laparoscopic Total Excision.

    Uyanikoglu, Hacer; Dusak, Abdurrahim


    Giant ovarian cysts, ≥15 cm in diameter, are quite rare in women of reproductive age. Here, we present a case of ovarian cyst with unusual presentation treated by laparoscopic surgery. On histology, mass was found to be mature cystic teratoma. The diagnostic and management challenges posed by this huge ovarian cyst were discussed in the light of the literature.

  18. Unique expression of 35 KDa protein in serum and cystic fluid of women with malignant ovarian cysts substantiates its role in disease progression

    Gulfam Ahmad; Muhammad Arslan


    Objective:The present study was undertaken as a part of a continuing search for proteomic based approaches for the diagnosis of ovarian cancers. Methods:The study comprised four groups of women with: i): malignant ovarian cysts, ii) benign ovarian cysts, iii): breast cancer (positive controls) and, iv) healthy females (negative controls). Serum and cystic fluids were processed for gel electrophoresis (SDS-PAGE). Serum and cystic follicular fluid estradiol and testosterone concentrations were measured by ELISA. Results:Proteomics analysis revealed the presence of a uniquely expressed protein with MW of 35 kDa in the serum and cystic fluid of patients with malignant ovarian cysts. On the other hand a protein of 100 kDa was not expressed in malignant ovarian patients whereas it was differentially expressed in the cystic fluid and serum of other three groups. Although mean values of estradiol levels were discernibly higher in patients with benign ovarian cysts as compared to those with malignant ovarian cysts and of positive and negative controls, difference was not significant. Mean concentrations of estradiol were significantly higher in cystic fluid aspirated from benign cysts as compared to that from malignant cysts. Conclusions:Taken together these data indicate a uniquely expressed protein of 35 kDa in patients with malignant ovarian cysts that may serve as a specific protein biomarker for the differential diagnosis of the ovarian cancer. However, a much larger sample of subjects is required to validate and confirm these findings.

  19. Cryopreservation of ovarian tissue and in vitro matured oocytes in a female with mosaic Turner syndrome: Case Report.

    Huang, J Y J; Tulandi, T; Holzer, H; Lau, N M; Macdonald, S; Tan, S L; Chian, R C


    We report a novel approach of fertility preservation in a young woman with mosaic Turner syndrome. A 16-year-old female with 20% 45XO and 80% 46XX karyotype underwent laparoscopic ovarian wedge resection. Before performing ovarian tissue cryopreservation, all visible follicles on the ovarian surface were aspirated. We recovered 11 immature germinal vesicle stage oocytes, which were subjected to in vitro maturation (IVM). Eight oocytes that matured (73% maturation rate) were cryopreserved by vitrification. The combination of ovarian tissue cryobanking and immature oocyte collection from the tissue followed by IVM and vitrification of matured oocytes represent a promising approach of fertility preservation for young women with mosaic Turner syndrome.

  20. Vitrification of in vitro matured oocytes collected from surplus ovarian medulla tissue resulting from fertility preservation of ovarian cortex tissue

    Yin, Huiqun; Jiang, Hong; Kristensen, Stine Gry


    PURPOSE: The aim of the study was to investigate the maturation rate of immature oocytes collected from ovarian medulla tissue normally discarded during preparation of ovarian cortical tissue for fertility preservation. Further we evaluated survival of derived MII oocytes following vitrification...... and warming. METHODS: 36 patients aged from 8 to 41 years who had one ovary excised for fertility preservation were included. Oocytes were collected from the medulla tissue and matured in vitro 44-48 h followed by vitrification. Number of oocytes collected, the rates of maturation and post-warming survival...... of cortical tissue may pose a risk of relapse, but the IVM approach is currently too inefficient to be the only method used for fertility preservation....

  1. Fertility parameters of dairy cows with cystic ovarian disease after treatment with gonadotrophin-releasing hormone.

    Hooijer, G A; van Oijen, M A; Frankena, K; Valks, M M


    Fertility data were collected every four weeks for 10 years from 40 herds of Holstein-Friesian dairy cattle. The data collected during 925 lactations from cows with cystic ovarian disease which were treated with 500 microg gonadorelin were compared with data from a control group of 13,869 normal lactations. The intervals between parturition and first insemination and between parturition and conception were significantly shorter (P<0.001) in the normal cows, but the interval between first insemination and conception was not. The overall conception rate tended to be higher (P<0.10) in the normal cows, but the conception rate after the first insemination was significantly higher (P<0.001) and the number of services per conception was significantly lower (P=0.008) in the normal cows.

  2. Ovarian steroidogenesis and the role of sex steroid hormones on ovarian growth and maturation of the Japanese eel.

    Kazeto, Yukinori; Tosaka, Ryota; Matsubara, Hajime; Ijiri, Shigeho; Adachi, Shinji


    Three sex steroid hormones, estradiol-17β (E2), 11-ketotestosterone (11-KT), and 17α,20β-dihydroxy-4-pregnen-3-one (DHP), are well established as primary estrogen, androgen, and progestin, respectively, in teleost fish. Japanese eel, Anguilla japonica, would be a suitable candidate to study ovarian steroid physiology of fish because the ovarian growth and steroidogenesis is dormant under laboratory condition but can be induced by administration of exogenous gonadotropic reagents. In this review, we summarized our work on the function and production of sex steroid hormones in the ovary of the Japanese eel during ovarian growth and oocyte maturation artificially induced by treatment with extract of salmon pituitary. In vitro and in vivo assays suggest that 11-KT and E2 play primary roles in previtellogenic and vitellogenic growth of oocytes, respectively, whereas DHP is essential for induction of final oocyte maturation. We also reviewed the correlation between ovarian steroidogenesis to produce these sex steroid hormones, serum titers and gene expression.

  3. Hypercalcemia Associated with a Malignant Brenner Tumor Arising from a Mature Cystic Teratoma

    Michael C. Honigberg


    Full Text Available A 60-year-old woman presented with abdominal pain and weight loss and was found to have serum calcium of 15.0 mg/dl. Serum parathyroid hormone-related peptide (PTHrP returned elevated. Imaging suggested bilateral mature cystic teratomas. Her hypercalcemia was treated initially with intravenous saline, as well as intramuscular and subcutaneous calcitonin. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, and final pathology revealed malignant Brenner tumor in association with a mature cystic teratoma. Her postoperative PTHrP returned less than assay, and her total and ionized calcium fell below normal, requiring supplemental calcium and vitamin D. At follow-up one month after discharge, her calcium had normalized. We present the first reported case of hypercalcemia occurring in association with a malignant Brenner tumor. Malignancy-associated hypercalcemia occurs via four principal mechanisms: (1 tumor production of PTHrP; (2 osteolytic bone involvement by primary tumor or metastasis; (3 ectopic activation of vitamin D to 1,25-(OH2 vitamin D, and (4 ectopic production of parathyroid hormone. PTHrP-mediated hypercalcemia is the most common mechanism and was responsible in this case. In patients with paraneoplastic hypercalcemia who undergo surgical treatment, close monitoring and management of serum calcium is necessary both pre- and postoperatively.

  4. Ovarian follicle maturation and ovulation: An integrated perspective

    Patino, R.; Thomas, P.; Yoshizaki, G.


    Numerous studies with teleosts have addressed the regulation and mechanisms of oocyte maturation, but largely at the exclusion of ovulation. A smaller but still considerable number of studies have focused on ovulation, and ignored maturation. Consequently, little is known about the mechanistic linkages between these two events. New information is presented here indicating that luteinizing hormone regulates the acquisition not only of oocyte maturational competence, but also ovulatory competence. The thesis is presented that maturation and ovulation are closely integrated and overlapping events that are best viewed conceptually and experimentally as parts of a functional whole. ?? 2004 Kluwer Academic Publishers.

  5. Primary retroperitoneal mature cystic teratoma with focal enteric type adenocarcinoma in a post-partum woman: report of a case with literature review.

    Hong, Wei; Dumoff, Kimberly L; Torigian, Drew A; Bing, Zhanyong


    Teratomas are characterized by containing tissue from all three germinal cell layers. Occasionally, somatic type malignancies develop within a mature cystic teratoma. We reported here a rare case of enteric type adenocarcinoma, with associated dysplastic epithelial precursor lesion, arising within a mature cystic teratoma in the retroperitoneum of a 30-year-old woman status post vaginal delivery 11 weeks earlier. The mass is 17.5 cm and cystic. A polypoid mass component measuring 4.7×4.2×2.5 cm was located inside the cystic component. Microscopically, the majority of the specimen was a mature cystic teratoma with all three germinal cell layers. The polypoid mass component was an adenocarcinoma with an adjacent dysplastic epithelial precursor lesion. The adenocarcinoma was diffusely positive for CK20 and CDX-2, and focally positive for CD7, indicating enteric differentiation. A brief review of retroperitoneal mature cystic teratomas with associated somatic type malignancy was performed.

  7. Clinical efficacy of Ayurveda treatment regimen on Subfertility with Poly Cystic Ovarian Syndrome (PCOS).

    Dayani Siriwardene, S A; Karunathilaka, L P A; Kodituwakku, N D; Karunarathne, Y A U D


    Poly Cystic Ovarian Syndrome (PCOS) is the most common endocrinopathy in women of reproductive age, resulting from insulin resistance and the compensatory hyperinsulinemia. This results in adverse effect on multiple organ systems and may result in alteration in serum lipids, anovulation, abnormal uterine bleeding and infertility. According to Ayurvedic view PCOS can be correlated with Aarthava Kshaya. It was revealed that most of subfertility patients who were presented Osuki Ayurveda Centre suffered from the PCOS. Therefore the present study was carried out for the clinical evaluation of the efficacy of Ayurveda treatment regimen on subfertility with PCOS. Total 40 patients were selected by using purposive sampling method. According to the Ayurveda theories of Shodhana, Shamana and Tarpana, the treatment was conducted in 3 stages for the duration of 6 months. The response to the treatment was recorded and therapeutic effects were evaluated by symptomatic relief and through Trans Vaginal Scan and LH, FSH hormone levels. The results revealed that, subfertility due to PCOS can be cured successfully by using this Ayurveda treatment regimen.

  8. Treatment of cystic ovarian disease in dairy cows with gonadotrophin-releasing hormone: a field study.

    Hooijer, G A; Frankena, K; Valks, M M; Schuring, M


    In a field trial in the Netherlands 765 dairy cows were treated during 869 lactations with 500 micrograms gonadotrophin-releasing hormone (gonadorelin i.m.) for cystic ovarian disease (COD) between June 1987 and April 1996. COD was defined as the presence of a large follicle (> 2.5 cm) on one or both of the ovaries in the absence of a corpus luteum. Two treatment groups were formed, based on the interval from parturition to first treatment, with day 60 being the cut-off between groups 1 and 2. The aim of this study is to examine whether there is a relationship between the moment of diagnosis and treatment (before or after day 60 post partum) and its result. In group 1 90.0% of first treatments were effective and in group 2 93.3% (p = 0.08). This was reflected by the slightly higher number of treatments needed for animals in group 1 (1.11 versus 1.07, p = 0.08). The efficacy rate after one treatment did not significantly differ between the groups (1.63 versus 1.69, p = 0.40) and nor did the interval between 1st insemination after treatment and conception (p < 0.63). In conclusion, it can be stated that gonadorelin is effective as therapy irrespective of the timing of diagnosis and treatment.

    Objective:To investigate some blood biochemical parameters in anoestrous dairy cows with cystic ovarian follicles(COF) during the first two months post partum and the effect of hCG-PGF2α-GnRH treatment on their reproductive response.Methods:The investigation was performed on20 lactatingHolstein cows, divided into two groups: control group(n=8) and treated group (n=12).All animals had cystic ovarian follicles, detected during the two consecutive transrectal ultrasound examinations at7-day interval.Blood samples from each animal were collected on the day of second ultrasonography(Day0) and subjected to a hormonal and biochemical analysis. Treated cows were subjected to another ultrasound examination on day of prostaglandin injection and the presence of corpus luteum was recorded.The control animals were not treated, while the treated group received1500IU hCG on day0,PGF2α500 mg on day7 and100 μgGnRH 48 hours latter.Eighteen hours afterGnRH administration animals bearing corpus luteum on Day7 were artificiallly inseminated.The last ultrasound examination was made forty days after start of the threapy.On the base of the obtained results, cumulative oestrous activity, cumulative ovulation rate, pregnancy rate andCOF persistence were determined.Results:The blood analysis in the both groups onDay0 showed significantly(P<0.05) lower mean concentration of progesterone, glucose and inorganic phosphate compared to the reference range values for cyclic dairy cows.Cumulative oestrous activity(91.7%) and cumulative ovulation rate(75.0%) were considerably higher(P<0.05) in treated group than control group, whereas the cystic follicle persistence(25.0%) was lower(P<0.05) in the treated group than control group.Conclusions:The present study confirmed the thesis for low blood levels of glucose and inorganic phosphate in cows presenting cystic ovarian follicles.It also indicated significant improvement of cumulative oestrous activity and ovulation rate in animals subjected toh

  10. Effect of ovarian hormones on maturation of dendritic cells from peripheral blood monocytes in dogs

    WIJEWARDANA, Viskam; SUGIURA, Kikuya; WIJESEKERA, Daluthgamage Patsy H.; HATOYA, Shingo; NISHIMURA, Toshiya; KANEGI, Ryoji; USHIGUSA, Takahiro; INABA, Toshio


    Previously, we reported that ovarian hormones affect the immune response against E. coli isolated from the dogs affected with pyometra. In order to investigate mechanisms underlying the immune modulation, we examined the effects of ovarian hormones on the generation of dendritic cells (DCs), the most potent antigen presenting cell. DCs were differentiated from peripheral blood monocytes (PBMOs) using a cytokine cocktail. Both estrogen receptor and progesterone receptors were expressed by the PBMOs and immature DCs. When various ovarian hormones were added to the culture for the DC differentiation, progesterone significantly decreased the expression of DC maturation markers, such as CD1a, CD80 and CD86, on mature DCs. Conversely, the addition of estrogen to the cultures increased the expression of CD86, but not other maturation makers. Furthermore, DCs differentiated in the presence of progesterone did not stimulate allogeneic mononuclear cells in PB. Taken together, these results indicate that progesterone diminishes the maturation of DCs, leading to decreased immune responses against invading pathogens. PMID:25715707

  11. N Acetyl Cysteine, A novel Remedy for Poly Cystic Ovarian Syndrome

    Nasibeh Amirzargar


    Full Text Available Background: Poly cystic ovarian syndrome (PCOS is the most prevalent endocrinopathy among womenand the most common underlying diagnosis for anovulatory infertility. The role of insulin-resistance(IR and hyperinsulinemia in pathophysiology and clinical manifestations of the syndrome depicts theimportance of evaluation of the efficacy of insulin reducing medications. N acetyl cysteine (NAC inhibitsoxidative stress and prevents hyperglycemia induced insulin resistance. This study aims at evaluating theeffects of NAC on manifestations of the disease as well as improvement of fertility status.Materials and Methods: Through a prospective double-blind clinical trial, 46 patients were randomlydivided into one intervention and one control group. The two groups were treated for six weeks aftersimilarity was allocated. All clinical and biochemical indicators were recorded in the early follicularphase both before and after treatment.Results: From each group, 18 patients were ultimately evaluated. In the first group, ovulation rateincreased as compared to the control group. A significant decrease in weight, body mass index (BMI,and waist/hip ratio was also observed. Fast blood sugar (FBS, serum insulin, total cholesterol, lowdensity lipoprotein (LDL levels, and HOMA-IR index also dropped while high density lipoproteinHDL levels elevated significantly. No significant change was reported in luteinizing hormone (LH,FSH, PRL, LH/FSH levels and glucose/insulin ratio. The control group remained unchanged.Conclusion: N- Acetyl Cysteine improves lipid profile, hormonal levels, ovulation status, and longtermhealth of women with PCOS. Considering its limited adverse effects, it can be regarded as asubstitute for insulin reducing medications in treatment of these patients.

  12. Mature Cystic Teratoma of the Fallopian Tube in a Postmenopausal Woman: A Case Report and Review of the Literature

    Sari, Mustafa Erkan; Ozdemir, Ozhan; Kadirogullari, Pinar; Ertugrul, Funda Arpaci; Atalay, Cemal Resat


    Background. Mature cystic teratomas of the fallopian tube are extremely rare and only 54 cases have been reported in the literature. In this paper, we report a mature cystic teratoma of the fallopian tube in a postmenopausal woman and we report the review of literature of tubal cystic teratomas. Case. A 62-year-old, gravida 4 postmenopausal woman presented with pain in the right lower abdominal region for a long time. An 88 × 72 × 95 mm heterogeneous mass which contained calcifications and lipoid components was detected in the right adnexal region by transvaginal ultrasonogram (TV-USG). Serum tumour markers, namely, CA125, CA15-3, and CA19-9, were within normal range. A laparotomy revealed a 9 × 10 cm cystic mass within the fimbrial region in the right fallopian tube, and right salpingoopherectomy was performed consequently. Microscopic examination revealed squamous epithelium with sebaceous glands and hair follicles, and pseudostratified ciliated respiratory epithelium with cartilage and mucous glands. Because the frozen section resulted in a benign dermoid cyst, no further operative procedure was performed. The postoperative follow-up was uneventful and the patient was discharged on the second postoperative day. Conclusion. In cases of undetermined pelvic or abdominal masses, a teratoma of the fallopian tube should be considered. PMID:25667777

  13. Ovarian localization of 11β-hydroxysteroid dehydrogenase (11βHSD): effects of ACTH stimulation and its relationship with bovine cystic ovarian disease.

    Amweg, A N; Salvetti, N R; Stangaferro, M L; Paredes, A H; Lara, H H; Rodríguez, F M; Ortega, H H


    Cystic ovarian disease (COD) is an important cause of infertility in cattle, and ACTH has been involved in regulatory mechanisms related to ovarian function associated with ovulation, steroidogenesis, and luteal function. Here, we examined the localization of 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) and 11βHSD2 proteins in the ovary of healthy cows and animals with spontaneous and ACTH-induced COD and the in vitro response of the follicular wall exposed to ACTH. After stimulation by ACTH, we documented changes in 11βHSD expression and cortisol secretion by the follicular wall of large antral and follicular cysts. Follicular cysts showed a higher constitutive expression of both enzymes, whereas ACTH induced an increase in 11βHSD1 in tertiary follicles and follicular cysts and a decrease in 11βHSD2 in follicular cysts. Moderate expression of 11βHSD1 was observed by immunohistochemistry in granulosa of control animals, with an increase (P cortisol in COD pathogenesis and in regulatory mechanisms of ovarian function.

  14. Suprasellar Mature Cystic Teratoma: An Unusual Location for an Uncommon Tumor

    Raed B. Sweiss


    Full Text Available Intracranial germ cell tumors are uncommon and account for only 0.3–3.4% of all intracranial tumors. Teratomas are a subset of these neoplasms, and their finding in brain structures is exceptionally rare, and occurrence within the skull base is quite novel. The authors report the case of a 57-year-old male patient who presented with vision changes, incontinence, ataxia, and altered mental status of 1 week’s duration. Imaging revealed a large intrasellar mass with suprasellar extension, involvement of the ventricular system, and marked hydrocephalus with the enlargement of the lateral and third ventricles. The patient underwent a pterional craniotomy/transsylvian approach for resection of the mass. Postoperative histological examination of the resected mass was confirmatory for a mature cystic teratoma. This was followed by radiotherapy, stereotactic radiosurgery, and adjuvant radiotherapy. At the most recent followup, approximately 4 years later, the patient is doing well with improved vision since the operation. This report highlights our experience with a teratoma in a very unusual location, and we review the relevant literature.

  15. Induction of ovarian maturation in Penaeus monodon by molecular signal interventional approach.

    Devaraj, Halagowder; Saravanakumar, Marimuthu; Thiyagu, Mani


    Vitellogenin (VTG) synthesis in the hepatopancreas and ovary is negatively regulated by vitellogenesis-inhibiting hormone (VIH) produced in the neurosecretory cell of X-organ/sinus gland complex of the eyestalks of penaeid shrimp. Eyestalk ablation is used commercially to induce ovarian maturation in shrimps which leads to an eventual loss of the spawner. The aim of the present study was to understand the molecular mechanism of VIH regulation in ovarian development and its inhibition of VTG gene expression by using a MEK-specific inhibitor (U0126). The real-time quantitative PCR results showed VTG mRNA level was progressively increased in the ovary and hepatopancreas of unilateral eyestalk-ablated and inhibitor-treated shrimps. Western blot analysis also showed that phosphoMEK was detected only in the unilateral eyestalk-ablated and control shrimp, whereas phospho-MEK was not detected in inhibitor-treated shrimp. DAX-1, SF-1, and StAR expression correlated with changes in VIH mRNA and altered phospho-ERK levels. This is consistent with the hypothesis that suppression of DAX-1 results in SF-1-mediated StAR protein upregulation of estradiol that is implicated in vitellogenesis. This is the first report that demonstrates the molecular mechanism of VIH suppression via MEK pathway to induce ovarian maturation in female Penaeus monodon by molecular signal intervention, a less-invasive method than traditional eyestalk ablation.

  17. Pre- and postnatal nutritional histories influence reproductive maturation and ovarian function in the rat.

    Deborah M Sloboda

    Full Text Available BACKGROUND: While prepubertal nutritional influences appear to play a role in sexual maturation, there is a need to clarify the potential contributions of maternal and childhood influences in setting the tempo of reproductive maturation. In the present study we employed an established model of nutritional programming to evaluate the relative influences of prenatal and postnatal nutrition on growth and ovarian function in female offspring. METHODS: Pregnant Wistar rats were fed either a calorie-restricted diet, a high fat diet, or a control diet during pregnancy and/or lactation. Offspring then were fed either a control or a high fat diet from the time of weaning to adulthood. Pubertal age was monitored and blood samples collected in adulthood for endocrine analyses. RESULTS: We report that in the female rat, pubertal timing and subsequent ovarian function is influenced by the animal's nutritional status in utero, with both maternal caloric restriction and maternal high fat nutrition resulting in early pubertal onset. Depending on the offspring's nutritional history during the prenatal and lactational periods, subsequent nutrition and body weight gain did not further influence offspring reproductive tempo, which was dominated by the effect of prenatal nutrition. Whereas maternal calorie restriction leads to early pubertal onset, it also leads to a reduction in adult progesterone levels later in life. In contrast, we found that maternal high fat feeding which also induces early maturation in offspring was associated with elevated progesterone concentrations. CONCLUSIONS: These observations are suggestive of two distinct developmental pathways leading to the acceleration of pubertal timing but with different consequences for ovarian function. We suggest different adaptive explanations for these pathways and for their relationship to altered metabolic homeostasis.

  18. Effects of thermal regime on ovarian maturation and plasma sex steroids in farmed white sturgeon, Acipenser transmontanus

    Webb, M.A.H.; Van Eenennaam, J. P.; Feist, G.W.; Linares-Casenave, J.; Fitzpatrick, M.S.; Schreck, C.B.; Doroshov, S.I.


    Recently, commercial aquaculture farms in Northern California have exposed gravid, cultured white sturgeon females to cold water (12 ?? 1??C) throughout the late phase of vitellogenesis and ovarian follicle maturation resulting in improved ovulation rates and egg quality. However, the optimum timing for transfer of broodfish to the cold water and the capacity of transferred broodfish to maintain reproductive competence over an extended time in cold water had not been evaluated. Gravid white sturgeon females that have been raised at water temperatures of 16-20??C were transported to either cold water (12 ?? 1??C; Group 1) in November 1997 or maintained in ambient water temperatures (10-19??C; Group 2) until early spring. In March 1998, half of the fish in Group 2 had regressed ovaries, but the remaining females had intact ovarian follicles and were transported to the cold water. Ovarian follicles and blood were collected from females until they reached the stage of spawning readiness (determined by germinal vesicle position and an oocyte maturation assay) or underwent ovarian regression. Exposure of gravid sturgeon females to ambient water temperatures (14.5 ?? 2.3??C, mean ?? S.D.) from October to March led to a decrease in plasma sex steroids and a high incidence of ovarian regression in fish with a more advanced stage of oocyte development. Transfer of females with intact ovarian follicles to cold water (12 ?? 1??C) in the fall or early spring resulted in normal ovarian development in the majority of females. Holding females in cold water does not seem to override their endogenous reproductive rhythms but extends their capacity to maintain oocyte maturational competence over a longer period of time. A temperature-sensitive phase in ovarian development may occur during the transition from vitellogenic growth to oocyte maturation, and the degree and timing of sensitivity to environmental temperature are dependent on the female's endogenous reproductive rhythm

    Zhang Ping


    Full Text Available Abstract Background Preoperative characterization of complex solid and cystic adnexal masses is crucial for informing patients about possible surgical strategies. Our study aims to determine the usefulness of apparent diffusion coefficients (ADC for characterizing complex solid and cystic adnexal masses. Methods One-hundred and 91 patients underwent diffusion-weighted (DW magnetic resonance (MR imaging of 202 ovarian masses. The mean ADC value of the solid components was measured and assessed for each ovarian mass. Differences in ADC between ovarian masses were tested using the Student’s t-test. The receiver operating characteristic (ROC was used to assess the ability of ADC to differentiate between benign and malignant complex adnexal masses. Results Eighty-five patients were premenopausal, and 106 were postmenopausal. Seventy-four of the 202 ovarian masses were benign and 128 were malignant. There was a significant difference between the mean ADC values of benign and malignant ovarian masses (p -3 mm2/s may be the optimal one for differentiating between benign and malignant tumors. Conclusions A high signal intensity within the solid component on T2WI was less frequently in benign than in malignant adnexal masses. The combination of DW imaging with ADC value measurements and T2-weighted signal characteristics of solid components is useful for differentiating between benign and malignant ovarian masses.

    Objective: To evaluate the effects of in vitro maturation (IVM) of oocytes in the infertile patients with polycystic ovarian syndrome(PCOS).Methods:The infertile patients with PCOS who underwent IVM or IVF/ICSI from January 2004 to August 2005 were studied retrospectively. 68 unstimulated cycles (48 cases) underwent IVM as IVM group, 42 cycles (39 cases) underwent IVF/ICSI as control group. Main outcomes including the number of oocytes retrival, the rates of fertilization, embryo cleavage, implantation, pregnancy, miscarriage, ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy were assessed. Results: No FSH was administered in IVM group and the mean number of FSH used was (25±6.2) ampoules in control group. When compared with control group, women in IVM group had significant increase in fertilization rate (70.7% versus 63.9%) and decrease in cleavage rate (87.9% versus 99.4%) and ovarian hyperstimulation syndrome (0 versus 7.1%). No significant differences between IVM group and control group were found in the number of oocytes obtained, implantation rate, clinical pregnancy rate, miscarriage rate and multiple pregnancy rate.Conclusion:Our results suggested that for infertile PCOS women who required assisted conception treatment, IVM is a more economical method with less OHSS complication than that of conventional IVF treatment.

  1. An Uncommon Case of Adolescent Ovarian Teratoma Incarcerated in Inguinal Hernia.

    Pensabene, Marco; Girgenti, Vincenza; Cimador, Marcello; Li Voti, Giuseppe; Rodolico, Vito; Siracusa, Fortunato


    Mature cystic teratoma is the most frequent benign ovarian neoplastic lesion in adolescents and is generally composed of fully differentiated tissue arising from multipotential three germinal layers. It accounts for approximately 50% of benign ovarian tumors in childhood. Rarely, a bilateral, synchronous, or metachronous presentation can be observed, supporting a conservative approach as the first surgical approach. We report a case of an ovarian mature cystic incarcerated in indirect inguinal hernia in a 15-year-old girl undergoing ovary-sparing surgery. To our knowledge this is the first case of such lesion incarcerated in an inguinal hernia reported in literature.

  3. Ovarian mucinous cystic tumor with sarcoma-like mural nodules and multifocal anaplastic carcinoma: a case report.

    Zheng, Jinfeng; Geng, Ming; Li, Peifeng; Li, Yi; Cao, Yongcheng


    A 48-year-old woman presented with left abdominal pain and fullness. Computed tomography scan revealed a multicystic mass with multifocal mural nodules. Histologic examination showed a mucinous cystic tumor with cystadenoma, borderline malignant cystadenoma and cystadenocarcinoma, which were associated with sarcoma-like mural nodules (SLMNs) and multifocal anaplastic carcinoma. Mural nodules showed a positive reaction for CD56 and vimentin, but were negative for cytokeratin 7 and SMA. She underwent postoperative chemotherapy and is currently under follow-up; no recurrence or metastases were found in the first year of follow-up. Ovarian mucinous cystic tumor with SLMNs and foci of anaplastic carcinoma is extremely rare. To our knowledge, this case reports the most complex neoplastic and reactive components. Our findings shed some light on the pathogenesis of this rather rare carcinoma. We think that the formation of SLMNs may be the result of the reactive proliferation of undifferentiated mesenchymal cells, while the anaplastic carcinoma may be derived from mucinous epithelium. Moreover, because of difficulties encountered in their differential diagnosis, we think that the existence of foci of anaplastic carcinoma along with SLMNs necessitates careful histologic and immunohistochemical analysis of mural nodules for the determination of treatment and prognosis.

  4. Vitrification of in vitro matured oocytes collected from antral follicles at the time of ovarian tissue cryopreservation

    Fasano Giovanna


    Full Text Available Abstract Background In the past few years, cryopreservation of ovarian tissue has become an established procedure proposed in many centers around the world and transplantation has successfully resulted in full-term pregnancies and deliveries in human. This prospective study aims to evaluate the feasibility of vitrifying in vitro matured oocytes (IVM isolated at the time of ovarian tissue cryopreservation to improve the efficiency of fertility preservation programs. Methods Oocyte-cumulus complexes were retrieved from freshly collected ovarian cortex by aspirating antral follicular fluid, and were matured in vitro for 24-48 h prior to vitrification. Oocytes were matured in an IVM commercial medium (Copper Surgical, USA supplemented with 75 mIU/ml FSH and 75 mIU/ml LH and vitrified using a commercial vitrification kit (Irvine Scientific, California in high security vitrification straws (CryoBioSystem, France. Oocyte collection and IVM rates were evaluated according to the age, the cycle period and the amount of tissue collected. Results Immature oocyte retrieval from ovarian tissue was carried out in 57 patients between 8 and 35 years of age, undergoing ovarian tissue cryopreservation. A total of 266 oocytes were isolated, 28 of them were degenerated, 200 were at germinal vesicle stage (GV, 35 were in metaphase I (MI and 3 displayed a visible polar body (MII. The number of oocytes collected was positively correlated with the amount of tissue cryopreserved (p p = 0.005. Oocytes were obtained regardless of menstrual cycle period or contraception. A total maturation rate of 31% was achieved, leading to the vitrification of at least one mature oocyte for half of the cohort. Conclusions The study showed that a significant number of immature oocytes can be collected from excised ovarian tissue whatever the menstrual cycle phases and the age of the patients, even for prepubertal girls.

    Meijide, Susana; Hernández, M Luisa; Navarro, Rosaura; Larreategui, Zaloa; Ferrando, Marcos; Ruiz-Sanz, José Ignacio; Ruiz-Larrea, M Begoña


    Female infertility involves an emotional impact for the woman, often leading to a state of anxiety and low self-esteem. The assisted reproduction techniques (ART) are used to overcome the problem of infertility. In a first step of the in vitro fertilization therapy women are subjected to an ovarian stimulation protocol to obtain mature oocytes, which will result in competent oocytes necessary for fertilization to occur. Ovarian stimulation, however, subjects the women to a high physical and psychological stress, thus being essential to improve ART and to find biomarkers of dysfunction and fertility. GSH is an important antioxidant, and is also used in detoxification reactions, catalysed by glutathione S-transferases (GST). In the present work, we have investigated the involvement of GST in follicular maturation. Patients with fertility problems and oocyte donors were recruited for the study. From each woman follicles at two stages of maturation were extracted at the preovulatory stage. Follicular fluid was separated from the oocyte by centrifugation and used as the enzyme source. GST activity was determined based on its conjugation with 3,4-dichloronitrobenzene and the assay was adapted to a 96-well microplate reader. The absorbance was represented against the incubation time and the curves were adjusted to linearity (R(2)>0.990). Results showed that in both donors and patients GST activity was significantly lower in mature oocytes compared to small ones. These results suggest that GST may play a role in the follicle maturation by detoxifying xenobiotics, thus contributing to the normal development of the oocyte.

    @@ Gynecologic and obstetric disorders presenting with abdominal pain are ectopic pregnancy, rupture of endometrial cysts, mature cystic teratoma and torsion of the adnexae. Hemorrhagic ovarian cysts, which included among the functional cysts, are often involved in acute abdomen leading to laparotomy intervention.

  7. Production of Nitric Oxide and Expression of Inducible Nitric Oxide Synthase in Ovarian Cystic Tumors

    Rosekeila Simões Nomelini


    Full Text Available Tumor sections from nonneoplastic (n=15, benign (n=28, and malignant ovarian tumors (n=20 were obtained from 63 women. Immunohistochemistry of the tumor sections demonstrated that inducible nitric oxide synthase (iNOS expression was increased in ovarian cancer samples compared to nonneoplastic or benign tumor samples. Using the Griess method, nitric oxide (NO metabolite levels were also found to be elevated in malignant tumor samples compared to benign tumor samples (P80 μM were more frequent than NO levels <80 μM, and iNOS expression in well-differentiated carcinomas was greater than in moderately/poorly differentiated carcinomas (P<.05. These data suggest an important role for NO in ovarian carcinogenesis.

  8. Changes in oviduct structure in the black tiger shrimp,Penaeus monodon, during ovarian maturation



    Objective:To examine the structure of the oviduct of the shrimp Penaeus monodon.Methods:The oviducts of P.monodon with three different major groups of ovarian development (Group (Gr.) 1:Stages Ⅰ & Ⅴ; Gr.2:Stages Ⅱ & Ⅲ; and Gr.3:Stage Ⅳ)were examined by light,transmission electron,and scanning electron microscopies,respectively.Results:The epithelium of the oviduct in Gr.1 was composed of tall simple columnar cells with their basal nuclei located on the basement membrane and its thick collagen fibers.In Gr.2,the oviduct seemed to produce some substances and their epithelial cells became transitional with centrally located nuclei and formed some vacuoles.Obviously,the epithelial cells in Gr.3 (at Stage Ⅳ) were disorganized,disrupted,and shed accumulated spherical secretory substances including some cellular contents into the lumen.Conclusions:The structural changes of the P.monodon oviduct were related to ovarian maturation stages (Grs.1-3).Prior to spawning,only the oviduct epithelium at ovary Stage Ⅳ produced and secreted a number of spherical secretion substances into the lumen.These substances may act as the oviductal lubricants to facilitate the spawning process.

  9. Ruptured ovarian cystic teratoma in pregnancy with diffuse peritoneal reaction mimicking advanced ovarian malignancy: a case report

    Maiti Sachchidananda


    Full Text Available Abstract Introduction This case illustrates the unusual complication of granulomatous peritonitis following rupture of a dermoid cyst in pregnancy resembling disseminated ovarian carcinoma. To the best of the authors' knowledge, this is the first report of this complication during advanced pregnancy in the literature. Case presentation A dermoid cyst ruptured during surgical removal in the second trimester of pregnancy in a 27-year-old primigravida. Postoperatively the patient suffered pulmonary embolism and leakage of sebaceous material through the abdominal wound. She gradually developed significant abdominal distension, gastrointestinal symptoms and lost more than 8 kg of weight in the 12 weeks postoperatively. The baby was delivered at 31 weeks by a technically challenging caesarean section owing to severe dense adhesions obscuring the uterus. Bowel resection was performed for suspected malignant infiltration and adhesion causing obstruction. She had a protracted convalescence with an ileostomy and mucus fistula. Histology confirmed granulation without malignancy. One year following the surgical treatment, she had recovered well and was planning her next pregnancy. Conclusion Although granulomatous peritonitis following rupture of a dermoid cyst is very rare, awareness is the key to diagnosis and appropriate management. Per-operative frozen section may be helpful.

  10. Bilateral ovarian cystic lymphangioma with chylous ascitis in pregnancy - a rare case report with review

    Archana Daddenavar


    Full Text Available Bilateral lymphangioma of the ovary being an extremely rare lesion, with chylous ascites and full term pregnancy, this is the first ever case in the world to be reported. Chylous ascites with pregnancy only 5 cases have been reported earlier. And above all, only 20 cases of ovarian lymphangioma are reported in the literature so far. Lymphangioma is usually asymptomatic and unilateral, presenting as an incidental finding during routine gynaecologic procedures. It is made up of aggregates of lymphatic spaces in ovarian stroma and the endothelial cells lining these spaces. The main differential diagnosis is an adenomatoid tumour which can be differentiated from the lymphangioma by immunohistochemical studies. We report this rare lesion in a case of 28 years old primigravida with 37 weeks of gestation with pregnancy induced hypertension with acute distension of abdomen with respiratory distress.

  14. The mechanism of regulation of ovarian maturation by red pigment concentrating hormone in the mud crab Scylla paramamosain.

    Zeng, Hui; Bao, Chenchang; Huang, Huiyang; Ye, Haihui; Li, Shaojing


    In this study a full-length cDNA (Sp-RPCH) was cloned from the eyestalk ganglia of the mud crab Scylla paramamosain. Sp-RPCH is 660 base pairs in length and its open reading frame encodes a precursor that is predicted to be processed into a 25-residue signal peptide, a mature red pigment concentrating hormone (RPCH, an octapeptide), and a 75-residue precursor-related peptide. Phylogenetic analysis indicates that it clusters with other crustacean RPCHs and belongs to the adipokinetic hormone/RPCH peptide superfamily. Sp-RPCH gene expression was detected, using an end-point polymerase chain reaction (PCR), not only in the eyestalk ganglia but also in the brain and thoracic ganglia. Quantified using a real-time PCR, Sp-RPCH gene expression levels in the three tissues fluctuated along a cycle of ovarian maturation, with the levels progressively increased from stages I to IV, after which the expression levels decreased (although they remained significantly higher than stage I levels) when the ovary reached the mature stage (stage V). It was demonstrated using a patch clamp analysis that synthetic RPCH was able to evoke a Ca(2+) current in dissociated brain neurons and synthetic RPCH significantly increased the mean oocyte diameter of the ovarian tissues co-cultured with the eyestalk ganglia, brain, or thoracic ganglia; the stimulatory effect of RPCH was absent when the nervous tissues were not included in the ovarian incubation. Animals administrated with RPCH had significantly higher levels of gonad-somatic index, hepatopancreas-somatic index, and vitellogenin gene expression, when compared to control animals receiving a saline injection. The combined results clearly show that RPCH is involved in ovarian maturation in the mud crab; the stimulatory effects of RPCH are likely mediated by its actions on the release from the nervous tissues of factor(s) that directly regulate vitellogenesis in the ovary and hepatopancreas.

  15. An automated technique for potential differentiation of ovarian mature teratomas from other benign tumours using neural networks classification of 2D ultrasound static images: a pilot study

    Al-karawi, Dhurgham; Sayasneh, A.; Al-Assam, Hisham; Jassim, Sabah; Page, N.; Timmerman, D.; Bourne, T.; Du, Hongbo


    Ovarian cysts are a common pathology in women of all age groups. It is estimated that 5-10% of women have a surgical intervention to remove an ovarian cyst in their lifetime. Given this frequency rate, characterization of ovarian masses is essential for optimal management of patients. Patients with benign ovarian masses can be managed conservatively if they are asymptomatic. Mature teratomas are common benign ovarian cysts that occur, in most cases, in premenopausal women. These ovarian cysts can contain different types of human tissue including bone, cartilage, fat, hair, or other tissue. If they are causing no symptoms, they can be harmless and may not require surgery. Subjective assessment by ultrasound examiners has a high diagnostic accuracy when characterising mature teratomas from other types of tumours. The aim of this study is to develop a computerised technique with the potential to characterise mature teratomas and distinguish them from other types of benign ovarian tumours. Local Binary Pattern (LBP) was applied to extract texture features that are specific in distinguishing teratomas. Neural Networks (NN) was then used as a classifier for recognising mature teratomas. A pilot sample set of 130 B-mode static ovarian ultrasound images (41 mature teratomas tumours and 89 other types of benign tumours) was used to test the effectiveness of the proposed technique. Test results show an average accuracy rate of 99.4% with a sensitivity of 100%, specificity of 98.8% and positive predictive value of 98.9%. This study demonstrates that the NN and LBP techniques can accurately classify static 2D B-mode ultrasound images of benign ovarian masses into mature teratomas and other types of benign tumours.

  16. Synchronous primary carcinoid tumor and primary adenocarcinoma arising within mature cystic teratoma of horseshoe kidney: a unique case report and review of the literature

    Perepletchikov Aleksandr M


    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin. Additionally, the

  17. Variation of prostaglandin E2 concentrations in ovaries and its effects on ovarian maturation and oocyte proliferation in the giant fresh water prawn, Macrobrachium rosenbergii.

    Prostaglandins (PGs) are important bioactive mediators for many physiological functions. In some decapod crustaceans, prostaglandin E2 (PGE2) has been detected in reproductive organs, and may play a role in the control of ovarian maturation. However, in the freshwater prawn, Macrobrachium rosenbergii, the presences of PGE2 and key enzymes for PGE2 biosynthesis, as well as its effects on ovarian maturation have not yet been investigated. In this study we reported the presence of PGE2, cyclooxygenase1 (COX1) and prostaglandin E synthase (PGES) in the ovarian tissues of M. rosenbergii, using immunohistochemistry. Intense immunoreactivities of PGE2 (PGE2-ir), COX1 (Cox1-ir) and PGES (PGES-ir) were detected in previtellogenic oocytes (Oc1 and Oc2), while the immunoreactivities were absent in the late vitellogenic oocytes (Oc4). This finding supports the hypothesis that the PGE2 biosynthesis occurs in the ovary of this prawn. To ascertain this finding we used LC-MS/MS to quantitate PGE2 concentrations during ovarian developmental cycle. The levels of PGE2 were significantly higher in the early ovarian stages (St I and II) than in the late stages (St III and IV). Moreover, we found that administration of PGE2 stimulated the ovarian maturation in this species by shortening the length of the ovarian cycle, increasing ovarian-somatic index, oocyte proliferation, and vitellogenin (Vg) level in the hemolymph.

Its characteristic radiologic findings allowed us to plan evacuation of intratumoral fluid in order to make the surgical procedure safe and less invasive. In addition, a hybrid thoracoscopic-open approach also provided safety and allowed a somewhat less invasive tumor resection than otherwise would have been required. The patient recovered well without recurrence at nine months’ follow-up, with full expansion of the right middle and lower lobes. Here we discuss the diagnosis and surgical procedure with reference to the literature.Keywords: mediastinal mature teratoma, rupture, acute pleuritis

  19. Comparative Proteomic Profiling Reveals Molecular Characteristics Associated with Oogenesis and Oocyte Maturation during Ovarian Development of Bactrocera dorsalis (Hendel)

    Li, Ran; Zhang, Meng-Yi; Liu, Yu-Wei; Zhang, Zheng; Smagghe, Guy; Wang, Jin-Jun


    Time-dependent expression of proteins in ovary is important to understand oogenesis in insects. Here, we profiled the proteomes of developing ovaries from Bactrocera dorsalis (Hendel) to obtain information about ovarian development with particular emphasis on differentially expressed proteins (DEPs) involved in oogenesis. A total of 4838 proteins were identified with an average peptide number of 8.15 and sequence coverage of 20.79%. Quantitative proteomic analysis showed that a total of 612 and 196 proteins were differentially expressed in developing and mature ovaries, respectively. Furthermore, 153, 196 and 59 potential target proteins were highly expressed in early, vitellogenic and mature ovaries and most tested DEPs had the similar trends consistent with the respective transcriptional profiles. These proteins were abundantly expressed in pre-vitellogenic and vitellogenic stages, including tropomyosin, vitellogenin, eukaryotic translation initiation factor, heat shock protein, importin protein, vitelline membrane protein, and chorion protein. Several hormone and signal pathway related proteins were also identified during ovarian development including piRNA, notch, insulin, juvenile, and ecdysone hormone signal pathways. This is the first report of a global ovary proteome of a tephritid fruit fly, and may contribute to understanding the complicate processes of ovarian development and exploring the potentially novel pest control targets.

  20. Mammalian osmolytes and S-nitrosoglutathione promote Delta F508 cystic fibrosis transmembrane conductance regulator (CFTR) protein maturation and function.

    Howard, Marybeth; Fischer, Horst; Roux, Jeremie; Santos, Bento C; Gullans, Steven R; Yancey, Paul H; Welch, William J


    In cystic fibrosis, the absence of functional CFTR results in thick mucous secretions in the lung and intestines, as well as pancreatic deficiency. Although expressed at high levels in the kidney, mutations in CFTR result in little or no apparent kidney dysfunction. In an effort to understand this phenomenon, we analyzed Delta F508 CFTR maturation and function in kidney cells under conditions that are common to the kidney, namely osmotic stress. Kidney cells were grown in culture and adapted to 250 mM NaCl and 250 mM urea. High performance liquid chromatography analysis of lysates from kidney cells adapted to these conditions identified an increase in the cellular osmolytes glycerophosphorylcholine, myo-inositol, sorbitol, and taurine. In contrast to isoosmotic conditions, hyperosmotic stress led to the proper folding and processing of Delta F508 CFTR. Furthermore, three of the cellular osmolytes, when added individually to cells, proved effective in promoting the proper folding and processing of the Delta F508 CFTR protein in both epithelial and fibroblast cells. Whole-cell patch clamping of osmolyte-treated cells showed that Delta F508 CFTR had trafficked to the plasma membrane and was activated by forskolin. Encouraged by these findings, we looked at other features common to the kidney that may impact Delta F508 maturation and function. Interestingly, a small molecule, S-nitrosoglutathione, which is a substrate for gamma glutamyltranspeptidase, an abundant enzyme in the kidney, likewise promoted Delta F508 CFTR maturation and function. S-Nitrosoglutathione-corrected Delta F508 CFTR exhibited a shorter half-life as compared with wild type CFTR. These results demonstrate the feasibility of a small molecule approach as a therapeutic treatment in promoting Delta F508 CFTR maturation and function and suggest that an additional treatment may be required to stabilize Delta F508 CFTR protein once present at the plasma membrane. Finally, our observations may help to

    Shin, Hyun Suk; Kim, Na Na; Choi, Young Jae; Habibi, Hamid R; Kim, Jae Won; Choi, Cheol Young


    The present study investigated the effects of exposure to different light spectra and intensities on ovarian maturation in yellowtail damselfish, Chrysiptera parasema over a 4-months period. We used a white fluorescent bulb and three different light-emitting diodes (LEDs: red, peak at 630nm; green, 530nm; blue, 450nm), at three different intensities each (0.3, 0.6, and 0.9W/m(2)). The effects of different illuminations were assessed by measuring the mRNA and protein expressions of vitellogenin (VTG) and estrogen receptor (ER), gonadosomatic index (GSI), and plasma estradiol-17β (E2) hormone level. For green and blue lights, significantly higher levels of VTG and ER expressions, GSI, and plasma E2 were obtained, compared to the other light spectra. Histological analysis revealed the presence of vitellogenic oocytes in fish exposed to short wavelengths (green and blue) light. In addition, we observed significantly greater ovarian maturation in fish exposed to low and medium light intensities. The results indicate that exposure to green low intensity lighting accelerates gonadal maturation, and is likely to facilitate development of more energy-efficient aquaculture procedures.

  3. Krukenberg Tumor: A Rare Cause of Ovarian Torsion

    Sameer Sandhu


    Full Text Available Ovarian torsion is the fifth most common gynecological surgical emergency. Ovarian torsion is usually associated with a cyst or a tumor, which is typically benign. The most common is mature cystic teratoma. We report the case of a 43-year-old woman who came to the Emergency Department with rare acute presentation of bilateral Krukenberg tumors, due to unilateral ovarian torsion. In this case report, we highlight the specific computed tomography (CT features of ovarian torsion and demonstrate the unique radiological findings on CT imaging. Metastasis to the ovary is not rare and 5 to 10% of all ovarian malignancies are metastatic. The stomach is the common primary site in most Krukenberg tumors (70%; an acute presentation of metastatic Krukenberg tumors with ovarian torsion is rare and not previously reported in radiology literature.

  4. Effects of maturation-inducing hormone on heterologous gap junctional coupling in ovarian follicles of Atlantic croaker

    Yoshizaki, G.; Patino, R.; Thomas, P.; Bolamba, D.; Chang, Xiaotian


    A previous ultrastructural study of heterologous (granulosa cell-oocyte) gap junction (GJ) contacts in ovarian follicles of Atlantic croaker suggested that these contacts disappear late during the process of resumption of oocyte meiosis. This observation suggested that, unlike scenarios proposed for a number of other species, uncoupling of GJ is not necessary for the onset of meiotic resumption in croaker follicles. However, the functionality of heterologous GJ contacts and the temporal association between maturation-inducing hormone (MIH)-induced changes in heterologous coupling and resumption of oocyte meiosis have not been examined in Atlantic croaker. These questions were addressed with a cell-cell coupling assay that is based on the transfer of a GJ marker, Lucifer Yellow, from oocytes to granulosa cells. Follicle-enclosed oocytes injected with Lucifer Yellow allowed transfer of the dye into the follicle cell layer, thus confirming that there is functional heterologous coupling between the oocyte and the granulosa cells. Dye transfer was observed in vitellogenic, full-grown/maturation-incompetent, and full-grown /maturation-competent follicles. Treatment of maturation-competent follicles with MIH caused a time-dependent decline in the number of follicles transferring dye. However, although GJ uncoupling in some of the follicles was observed before germinal vesicle breakdown (GVBD, index of meiotic resumption), about 50% of the follicles maintained the ability to transfer dye even after GVBD had occurred. Further, a known GJ inhibitor (phorbol 12-myristate 13-acetate) blocked heterologous GJ within a time frame similar to that seen with MIH but without inducing any of the morphological changes (including GVBD) associated with follicular maturation. In conclusion, uncoupling of heterologous GJ seems insufficient and unnecessary for the onset of meiotic resumption in ovarian follicles of Atlantic croaker. ?? 2001 Elsevier Science.

  5. Effects of 5α-dihydrotestosterone and 17β-estradiol on the mouse ovarian follicle development and oocyte maturation.

    Wataru Tarumi

    Full Text Available We have previously reported that androstenedione induces abnormalities of follicle development and oocyte maturation in the mouse ovary. In granulosa cells of the ovarian follicle, androstenedione is aromatized to 17β-estradiol (E2. To determine whether the androgen or estrogen acts directly on the follicle to induce the above-mentioned abnormalities, we compared the effects of a non-aromatizable androgen, 5α-dihydrotestosterone (DHT, with those of E2 on murine follicular development and oocyte maturation in a single follicle culture system. The high dose (10(-6 M of DHT prompted normal follicular development, and there was no effect on oocyte meiotic maturation after stimulation with human chorionic gonadotropin (hCG and epidermal growth factor (EGF. In contrast, culture with the high dose (10(-6 M of E2 delayed follicular growth and also suppressed proliferation of granulosa cells and antrum formation. Furthermore, culture with E2 delayed or inhibited oocyte meiotic maturation, such as chromosome alignment on the metaphase plate and extrusion of the first polar body, after addition of hCG and EGF. In conclusion, these findings demonstrate that E2, but not DHT, induces abnormalities of follicular development, which leads to delay or inhibition of oocyte meiotic maturation.

  6. Cryopreservation/transplantation of ovarian tissue and in vitro maturation of follicles and oocytes: Challenges for fertility preservation

    Agarwal Ashok


    Full Text Available Abstract Cryopreservation of ovarian tissue and in vitro follicle maturation are two emerging techniques for fertility preservation, especially in cancer patients. These treatment regimes are opening up more options and allow for more suitable choices to preserve fertility according to the patient's specific circumstances. If these technologies are to become widely accepted, they need to be safe, easy to perform and must obtain favorable results. The generation of healthy eggs with the normal genetic complement and the ability to develop into viable and healthy embryos requires tight regulation of oocyte development and maturation. Novel freezing techniques such as vitrification, along with whole ovary cryopreservation and three-dimensional follicle cultures, have shown favorable outcomes. The scope of this article is to take a comprehensively look at the challenges still faced in order for these novel technologies to be routinely employed with the aim of successful fertility preservation.

  7. Dynamics of ovarian maturation during the reproductive cycle of Metynnis maculatus, a reservoir invasive fish species (Teleostei: Characiformes

    Thiago Scremin Boscolo Pereira

    Full Text Available In this study, we evaluated the dynamics of ovarian maturation and the spawning processes during the reproductive cycle of Metynnis maculatus. Adult females (n = 36 were collected bimonthly between April 2010 and March 2011. The mean gonadosomatic index (GSI was determined, ovarian and blood samples were submitted for morphometric evaluation and the steroid plasma concentration was determined by ELISA. This species demonstrated asynchronous ovarian development with multiple spawns. This study revealed that, although defined as a multiple spawning species, the ovaries of M. maculatus have a pattern of development with a predominance of vitellogenesis between April and August and have an intensification in spawning in September; in October, a drop in the mean GSI values occurred, and the highest frequencies of post-ovulatory follicles (POFs were observed. We observed a positive correlation between the POF and the levels of 17α-hydroxyprogesterone. Metynnis maculatus has the potential to be used as a source of pituitary tissue for the preparation of crude extracts for hormonal induction; the theoretical period for use is from September to December, but specific studies to determine the feasibility of this approach must be conducted.

    Reproductive success stems from a finely regulated balance between follicular maturation and atresia, in which the role of carbohydrate structure is poorly understood. Here, we describe for the first time a fraction of purified recombinant human FSH that is capable of bringing about the cell death of granulosa cells and preventing follicular maturation in a rat model. Further analysis by mass spectrometry revealed the presence of the lectin Concanavalin-A (Con-A) within this fraction of recombinant FSH. Using both the fractionated FSH and Con-A, the observed cell death was predominantly located to the granulosa cells. Ex vivo culture of rat follicles demonstrated that follicle degeneration occurred and resulted in the release of a denuded and deteriorated oocyte. Moreover, in vivo experiments confirmed an increase in atresia and a corresponding reduction confined to follicle in early antral stage. As a mechanism of action, Con-A reduces ovarian proliferation, Von Willebrand staining, and angiogenesis. Based on the observation that Con-A may induce granulosa cell death followed by follicle death, our results further demonstrate that follicular carbohydrate moiety is changing under the influence of FSH, which may allow a carbohydrate-binding lectin to increase granulosa cell death. The physiological consequences of circulating lectin-like molecules remain to be determined. However, our results suggest a potential exploitation of carbohydrate binding in fertility and ovarian cancer treatment. This work may shed light on a key role of carbohydrates in the still obscure physiological process of follicular selection and atresia.

  9. First pregnancy and live birth resulting from cryopreserved embryos obtained from in vitro matured oocytes after oophorectomy in an ovarian cancer patient.

    Prasath, E B; Chan, M L H; Wong, W H W; Lim, C J W; Tharmalingam, M D; Hendricks, M; Loh, S F; Chia, Y N


    In vitro maturation (IVM) of immature oocytes retrieved from surgically resected ovaries has been proposed as a method of fertility preservation in ovarian cancer patients undergoing definitive surgery. While there had been several reports of successful derivation of mature oocytes and or embryos, there have been no reports as yet of successful pregnancies. In this case report, we present a pregnancy and live birth from a young patient, with stage IIIC ovarian cancer, who had undergone fertility sparing surgery. The immature oocytes recovered after oophorectomy were fertilized after IVM. The embryos obtained were cryopreserved and later transferred to achieve a singleton healthy pregnancy leading to a live birth.

    Patients with cystic fibrosis (CF) have mild defects in dental enamel. The gene mutated in these patients is CFTR, a Cl− channel involved in transepithelial salt and water transport and bicarbonate secretion. We tested the hypothesis that Cftr channels are present and operating in the plasma membran

  14. Comparison of ovarian maturation and spawning after unilateral eyestalk ablation of wild-caught and pond-reared Penaeus monodon

    Wen, W.; Yang, Q.; Ma, Z.; Jiang, S.; Qiu, L.; Huang, J.; Zhou, F.; Qin, J.G.


    The present study compares the efficiency of ovarian maturation and spawning success between wild-caught and pond-reared Penaeus monodon females after unilateral eyestalk ablation. The earliest spawning time after eyestalk ablation was 5.9 days in wild-caught females, which is significantly shorter than the spawning time in pond-reared females (10.5 days). Both wild-caught and pond-reared females repeatedly spawned after eyestalk ablation. On average, each wild-caught female spawned 2.94 times while each pond-reared female spawned only 1.09 times. The spawning induction rate, egg hatching rate, and the number of eggs per spawning were significantly greater in wild-caught females than in pond-reared females. However, the egg size was not significantly different between wild-caught and pond-reared females. Four shrimp sizes (60, 80, 100 and 120 (± 1.0) g) were tested in this study and body weight significantly affected ovarian induction in pond-reared females but not in wild-caught females. Within the same body-weight class, the egg number per spawn in wild-caught females was significantly greater than that in pond-reared females. The egg production per spawn of the pond-reared females in the 120-g size group was two times higher than that in the pond-reared females in the 80-g size group. In conclusion, the fecundity of wild-caught P. monodon females is significantly higher than that of pond-reared P. monodon females. In breeding pond-reared P. monodon, the recommended minimum body weight of females is over 80 g, and the desirable body weight is over 100 g. (Author)

  15. Immunohistochemical analysis of steroidogenic enzymes in ovarian-type stroma of pancreatic mucinous cystic neoplasms: Comparative study of subepithelial stromal cells in intraductal papillary mucinous neoplasms of the pancreas.

    Ishida, Kazuyuki; Sasano, Hironobu; Moriya, Takuya; Takahashi, Yayoi; Sugimoto, Ryo; Mue, Yoshiharu; Murakami, Keigo; Fujishima, Fumiyoshi; Nakamura, Yasuhiro; Morikawa, Takanori; Motoi, Fuyuhiko; Suzuki, Takashi; Unno, Michiaki; Sugai, Tamotsu


    Mucinous cystic neoplasms (MCNs) are generally defined as cyst-forming epithelial neoplasms that arise in the pancreas and harbor characteristic ovarian-type stroma beneath the epithelium. In this study, we compared the immunoreactivity of steroid-related factors in these subepithelial stromal cells in MCNs to those in intraductal papillary mucinous neoplasms (IPMNs) to further characterize this unique MCN ovarian-type stroma through evaluation of sex steroid biosynthesis. Twenty MCNs and twenty IPMNs were examined. Immunoreactivity of steroid hormone receptors, including estrogen receptor (ERα and ERβ), progesterone receptor (PR, PR-A, and PR-B), and androgen receptor (AR), was more frequently detected in MCN ovarian-type stromal cells than in IPMN stromal cells (P enzymes cytochrome P450 cholesterol side-chain cleavage enzyme (P450scc), cytochrome P450 17 alpha-hydroxylase (P450c17) and 3β-hydroxysteroid dehydrogenase (3β-HSD) showed immunoreactivity in 9/20 (45.0 %), 15/20 (75.0 %) and 13/20 (65.0 %), respectively, of ovarian-type stroma from MCN cases. These results demonstrate that the ovarian-type stroma of MCNs can express steroidogenic enzymes. Thus, the ovarian-type stroma of MCNs can produce sex steroids that may also act on these cells.

    Gultiken, Nilgun; Yarim, Murat; Yarim, Gul Fatma; Gacar, Ayhan; Mason, James Ian


    The purpose of this study was to compare the expression of 3β-hydroxystreroid dehydrogenase (3β-HSD) in the uterus and ovary of healthy dogs and those with cystic endometrial hyperplasia and/or pyometra complex (CEH-pyometra). Eighteen female dogs were included in the study. Eleven bitches with open cervix CEH-pyometra were included in the CEH-pyometra group and seven diestrus bitches in the control group. For immunostaining a rabbit polyclonal, one raised against recombinant human type 2 (adrenal/gonadal) 3β-HSD was used. Progesterone (P4) concentrations were not statistically different between the groups. Strongly stained large interstitial cell groups in the ovarian medulla were observed particularly in CEH-pyometra group although these cells in the control group were weakly or moderately stained and existed singly or paired. The expressions of 3β-HSD in luminal epithelium (42.40 ± 22.40% vs. 18.42 ± 13.15%, P pyometra group than those in the control group. The expression of 3β-HSD in CL was higher (29.38 ± 9.58% vs. 22.94 ± 4.97%) in CEH-pyometra group than that of control group although the differences were not significant (P > 0.05). Similarly, the significant increase in the expression of 3β-HSD in ovarian interstitial cells (33.86 ± 29.44 vs. 1.13 ± 2.97, P pyometra group compared to the control group. The study revealed that 3β-HSD expression in the endometrium of canine CEH-pyometra was significantly high. Copyright © 2016 Elsevier Inc. All rights reserved.

  17. A shut-down in expression of an insulin-like peptide, ILP-1, halts ovarian maturation during the overwintering diapause of the mosquito Culex pipiens.

    Sim, C; Denlinger, D L


    Short day-length is used to programme adult diapause in the mosquito, Culex pipiens. The downstream endocrine event that halts ovarian maturation is a shut-down in juvenile hormone (JH) production, and recent evidence suggests that the insulin signalling pathway may be a key upstream player in executing this developmental arrest. Genes encoding insulin-like peptides-1, -2 and -5 were identified in C. pipiens, and we report that transcript levels of insulin-like peptides-1 and -5 were significantly lower in diapausing females than in their nondiapausing counterparts. Genes encoding both insulin-like peptides-1 and -5 were suppressed using RNA interference in mosquitoes programmed for nondiapause, and ovarian maturation was monitored. Knocking down insulin-like peptide-1 with RNAi in nondiapausing mosquitoes resulted in a cessation of ovarian development akin to diapause, and this arrest in development could be reversed with an application of JH. Knocking down insulin-like peptide-5 did not alter ovarian development. These results are consistent with a role for insulin-like peptide-1 in the signalling pathway leading from the perception of short day-lengths to the shut-down in JH production that characterizes adult diapause in C. pipiens.

  19. Influence of negative energy balance on the reproductive performance after treatment of cystic ovarian disease with gonadotrophin-releasing hormone in dairy cows.

    Hooijer, G A; van Oijen, M A A J; Frankena, K; Noordhuizen, J P T M


    The aim of this study was to investigate whether a significant relation exists between the presence of a negative energy balance (NEB) in cows early in lactation and the reproductive performance after treatment with gonadotrophin-releasing hormone of cows with clinical cystic ovarian disease. Reproductive performance after treatment was assessed from the interval between treatment and first insemination (ITFI) and the interval between treatment and conception (ITC). Based on the outcome of the daily change of milk fat yield (Deltafatg) between the first and second milk recordings post-partum, cows were considered to have passed the NEB nadir (positive Deltafatg) or not (negative Deltafatg). Lactations (n = 430) were divided into four groups according to the interval between calving and first milk recording (ICMR): (i) 0-9 days; (ii) 10-19 days; (iii) 20-29 days; (iv) 30-49 days. The relation between a NEB-proxy parameter (Deltafatg) and reproductive performance was determined. A significant interaction existed for groups 1 and 3 (ICMR on 0-9 and 20-29 days post-partum respectively) with an increased and a decreased probability of being inseminated the first day after treatment (ITFI) respectively. However, no significant interaction was found between Deltafatg and the groups with regard to ITC.

  20. Distinguishing ovarian maturity of farmed white sturgeon (Acipenser transmontanus) by Fourier transform infrared spectroscopy: a potential tool for caviar production management.

    Lu, Xiaonan; Webb, Molly; Talbott, Mariah; Van Eenennaam, Joel; Palumbo, Amanda; Linares-Casenave, Javier; Doroshov, Serge; Struffenegger, Peter; Rasco, Barbara


    Fourier transform infrared spectroscopy (FT-IR, 4000-400 cm(-1)) was applied to blood plasma of farmed white sturgeon (N = 40) to differentiate and predict the stages of ovarian maturity. Spectral features of sex steroids (approximately 3000 cm(-1)) and vitellogenin (approximately 1080 cm(-1)) were identified. Clear segregation of maturity stages (previtellogenesis, vitellogenesis, postvitellogenesis, and follicular atresia) was achieved using principal component analysis (PCA). Progression of oocyte development in the late phase of vitellogenesis was also monitored using PCA based on changes in plasma concentrations of sex steroid and lipid content. The observed oocyte polarization index (PI, a measure of nuclear migration) was correlated with changes in plasma sex steroid levels revealed by FT-IR PCA results. A partial least squares (PLS) model predicted PI values within the range 0.12-0.40 (R = 0.95, SEP = 2.18%) from differences in spectral features. These results suggest that FT-IR may be a good tool for assessing ovarian maturity in farmed sturgeon and will reduce the need for the invasive ovarian biopsy required for PI determination.

  1. Ghrelin negatively affects the function of ovarian follicles in mature pigs by direct action on basal and gonadotropin-stimulated steroidogenesis.

    Rak-Mardyła, Agnieszka; Wróbel, Anna; Gregoraszczuk, Ewa L


    We previously showed that expression of ghrelin messenger RNA is significantly increased in the ovaries of cycling pigs but not in prepubertal animals and that ghrelin stimulates estradiol (E2) secretion by ovarian follicles in prepubertal animals. The present study investigated in vitro the role of ghrelin in regulating the ovarian steroidogenesis during estrus cycle in mature pigs. Small (SFs), medium (MFs), and large (LFs) ovarian follicles were collected on days 4 to 6, 10 to 12, and 16 to 18 of the estrous cycle from cycling pigs and exposed to 20, 100, and 500 pg/mL ghrelin for 24 hours. In additional experiments, MFs were exposed to ghrelin plus 100 ng/mL follicle-stimulating hormone (FSH) or luteinizing hormone (LH). Levels of progesterone (P4), testosterone (T), and E2 in culture medium were determined by enzyme-linked immunosorbent assay, and the expression of the steroid pathway enzymes 3β hydroxysteroid dehydrogenase (HSD), 17β-HSD, and cytochrome P450 aromatase (CYP19) was evaluated by Western blotting. Ghrelin had no effect on steroid secretion when present at 20 pg/mL, its concentration in follicular fluid, whereas at 100 pg/mL and 500 pg/mL, its concentration in serum, ghrelin significantly decreased secretion of P4, T, and E2. Moreover, all concentrations of ghrelin decreased steroid secretion in FSH- and LH-stimulated follicles. Western blot analysis showed that ghrelin inhibited expression of 3β-HSD, 17β-HSD, and CYP19 proteins. These results suggest that ghrelin, by direct inhibition of 3β-HSD, 17β-HSD, and CYP19 protein expression, inhibits LH- and FSH-stimulated steroid secretion by ovarian follicles, thus negatively affecting ovarian steroidogenesis in mature pigs.

  2. Concurrent cystic endometrial hyperplasia, ovarian luteoma and biliary cyst adenoma in an aged rabbit (Oryctolagus cuniculus):case report and literature review

    Askari Nasrin; Akhtardanesh Baharak; Kheirandish Reza


    A 6-year-old female nulliparous Dutch Rabbit (Oryctolagus cuniculus) was presented in shock status with a history of abdominal distention, inappetance, lethargy, polydipsia, diarrhea and weight loss since 2 weeks ago. There was no breeding history. Radiographic survey showed increased soft tissue opacity dorsal to the urinary bladder and ventral to the colon on the lateral view consistent with uteromegaly and severe intestinal distention resembling intussusceptions. Conservative treatment was failed and the animal died. In necropsy, ileocecal intussusception was noted as the main death factor. Thickened uterine endometrium in both horns was observed and the uterus was filled with mucoid fluid. Both ovaries were multilobulated and distended. On the other hand, a small cyst sized 1.5 × 2.5 cm was diagnosed on the liver surface. Several samples were obtained from lesions for histopathological evaluation. Histopathologically, dilated cystic glands of variable size lined by densely packed epithelium and hyperplasia of the endometrium resulting in irregular folds or papillar projection into the lumen were evident and the sections of ovaries revealed ovarian luteoma that composed of polyhedral cells with pale stained vacuolated cytoplasm, centrally located nuclei with distinct cytoplasmic borders and the cytoplasm of cells contain lipid droplet. The occurrence of biliary cyst adenoma was confirmed by microscopic examination of the mass that composed of multicystic space in different sizes lined by flattened to cuboidal biliary epithelium with papillary projections. These cysts were seperated by variable amount of connective tissue. The lack of postmortem investigations in aged rabbits reduced the incidence of neoplastic disease diagnosis in this species. Whereas uterine adenecarcinoma and lymphosarcoma were commonly reported in rabbits, luteoma and biliary cyst adenoma that are well described in this case report were uncommon in rabbit medicine.

  3. Cumulus cells gene expression profiling in terms of oocyte maturity in controlled ovarian hyperstimulation using GnRH agonist or GnRH antagonist.

    Rok Devjak

    Full Text Available In in vitro fertilization (IVF cycles controlled ovarian hyperstimulation (COH is established by gonadotropins in combination with gonadotropin-releasing hormone (GnRH agonists or antagonists, to prevent premature luteinizing hormone (LH surge. The aim of our study was to improve the understanding of gene expression profile of cumulus cells (CC in terms of ovarian stimulation protocol and oocyte maturity. We applied Affymetrix gene expression profiling in CC of oocytes at different maturation stages using either GnRH agonists or GnRH antagonists. Two analyses were performed: the first involved CC of immature metaphase I (MI and mature metaphase II (MII oocytes where 359 genes were differentially expressed, and the second involved the two GnRH analogues where no differentially expressed genes were observed at the entire transcriptome level. A further analysis of 359 differentially genes was performed, focusing on anti-Müllerian hormone receptor 2 (AMHR2, follicle stimulating hormone receptor (FSHR, vascular endothelial growth factor C (VEGFC and serine protease inhibitor E2 (SERPINE2. Among other differentially expressed genes we observed a marked number of new genes connected to cell adhesion and neurotransmitters such as dopamine, glycine and γ-Aminobutyric acid (GABA. No differential expression in CC between the two GnRH analogues supports the findings of clinical studies where no significant difference in live birth rates between both GnRH analogues has been proven.




    In two studies initiated in 1979 and 1981, 377 patients were treated for advanced epithelial ovarian cancer.

    In vitro fertilization (IVF) treatment is an effective therapy for infertility, but can result in the potentially life-threatening complication, ovarian hyperstimulation syndrome (OHSS). This study aimed to investigate whether kisspeptin-54 can be used to effectively and safely trigger oocyte maturation in women undergoing IVF treatment at high risk of developing OHSS. This was a phase 2, multi-dose, open-label, randomized clinical trial of 60 women at high risk of developing OHSS carried out during 2013-2014 at Hammersmith Hospital IVF unit, London, United Kingdom. Following a standard recombinant FSH/GnRH antagonist protocol, patients were randomly assigned to receive a single injection of kisspeptin-54 to trigger oocyte maturation using an adaptive design for dose allocation (3.2 nmol/kg, n = 5; 6.4 nmol/kg, n = 20; 9.6 nmol/kg, n = 15; 12.8 nmol/kg, n = 20). Oocytes were retrieved 36 h after kisspeptin-54 administration, assessed for maturation, and fertilized by intracytoplasmic sperm injection with subsequent transfer of one or two embryos. Women were routinely screened for the development of OHSS. Oocyte maturation was measured by oocyte yield (percentage of mature oocytes retrieved from follicles ≥ 14 mm on ultrasound). Secondary outcomes include rates of OHSS and pregnancy. Oocyte maturation occurred in 95% of women. Highest oocyte yield (121%) was observed following 12.8 nmol/kg kisspeptin-54, which was +69% (confidence interval, -16-153%) greater than following 3.2 nmol/kg. At all doses of kisspeptin-54, biochemical pregnancy, clinical pregnancy, and live birth rates per transfer (n = 51) were 63, 53, and 45%, respectively. Highest pregnancy rates were observed following 9.6 nmol/kg kisspeptin-54 (85, 77, and 62%, respectively). No woman developed moderate, severe, or critical OHSS. Kisspeptin-54 is a promising approach to effectively and safely trigger oocyte maturation in women undergoing IVF treatment at high risk of developing OHSS.

  6. Cystic Endometriosis in a Huge Degenerated Subserous Leiomyoma Mimicking Bilateral Multicystic Endometriomas in an Infertile Woman with Diminished Ovarian Reserve: A Rare Endometriotic Implantation.

    Hatirnaz, Safak; Colak, Sabri; Reis, Abdulkadir


    Uterine leiomyomas are the most common pelvic tumor in women. Leiomyoma can show atypical locations and degenerations and may not be easily differentiated from adnexal masses. Uterine leiomyoma can undergo cystic degeneration and is said to be found in 4% of all types of degenerations. The commonest type of degeneration is hyaline seen in 60% of patients. Usually uterine leiomyoma does not present as clinical and radiological diagnostic challenge. However, when leiomyoma undergoes massive cystic degeneration they may become clinical and radiological diagnostic dilemmas. The MRI showed a huge cystic mass protruding up to the pelvis not differentiated from bilateral endometriomas and accompanying subserous myomas. Surgery revealed that the mass is not bilateral endometriomas but a huge pedunculated leiomyoma with cystic degeneration and cystic endometriosis. Endometriosis is a troubling gynecologic condition occurring in 10% to 15% of women of reproductive age and is associated with fertility problems. As a peritoneal disease, the locations of endometriotic lesions are predominantly the ovaries (96.4%), followed by the soft tissue (2.8%), gastrointestinal tract (0.3%), and urinary tract (0.2%) and other rare locations. The presented case is multiple sized cystic endometriosis (endometriomas) located in a huge pedunculated subserous leiomyoma in an infertile woman having a history of laparoscopic bilateral endometrioma surgery. Conclusion. To our knowledge, this is the first reported case for endometriotic cysts (endometriomas) located in a huge cystic degenerated leiomyoma. PubMed search revealed no report concerning endometriotic implantation in the leiomyomas.

  7. A Case of Early-Stage Ovarian Carcinoid Tumor Metastasized to the Liver

    Seiji Kanayama


    Full Text Available We report a case of ovarian carcinoid tumor that recurred with multiple liver metastases and was successfully treated with chemoembolization. A 76-year-old woman was admitted to our hospital presented with abdominal distension and abnormal uterine bleeding for about 6 months. She presented with hyperestrogenic and androgenic manifestations such as vaginal bleeding with endometrial hyperplasia and hirsutism. Magnetic resonance (MR imaging revealed a large solid and cystic ovarian tumor of 17 cm at maximum diameter. On the basis of the clinical diagnosis of sex cord stromal tumor containing a mature cystic teratoma, she underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. The pathology report revealed that the mass in the left ovary was a carcinoid tumor, insular type, with mature cystic teratoma. Two years after surgical treatment, multiple liver metastases were revealed by abdominal CT. Hepatic arterial infusion of cisplatin was performed for 2 courses, and multiple metastatic nodules have remarkably reduced. No established chemotherapy or radiation therapy treatments are currently available for recurrent or advanced carcinoid tumors. Our paper suggests that chemoembolization with cisplatin may be effective in treatment of patients with multiple liver metastases of ovarian carcinoid tumor.

K.; Comninos, Alexander N.; Peters, Deborah; Buckley, Adam; Ratnasabapathy, Risheka; Prague, Julia K.; Salim, Rehan; Lavery, Stuart A.; Bloom, Stephen R.; Szigeti, Matyas; Ashby, Deborah A.; Trew, Geoffrey H.


    Context: In vitro fertilization (IVF) treatment is an effective therapy for infertility, but can result in the potentially life-threatening complication, ovarian hyperstimulation syndrome (OHSS). Objective: This study aimed to investigate whether kisspeptin-54 can be used to effectively and safely trigger oocyte maturation in women undergoing IVF treatment at high risk of developing OHSS. Setting and Design: This was a phase 2, multi-dose, open-label, randomized clinical trial of 60 women at high risk of developing OHSS carried out during 2013–2014 at Hammersmith Hospital IVF unit, London, United Kingdom. Intervention: Following a standard recombinant FSH/GnRH antagonist protocol, patients were randomly assigned to receive a single injection of kisspeptin-54 to trigger oocyte maturation using an adaptive design for dose allocation (3.2 nmol/kg, n = 5; 6.4 nmol/kg, n = 20; 9.6 nmol/kg, n = 15; 12.8 nmol/kg, n = 20). Oocytes were retrieved 36 h after kisspeptin-54 administration, assessed for maturation, and fertilized by intracytoplasmic sperm injection with subsequent transfer of one or two embryos. Women were routinely screened for the development of OHSS. Main Outcome Measure: Oocyte maturation was measured by oocyte yield (percentage of mature oocytes retrieved from follicles ≥ 14 mm on ultrasound). Secondary outcomes include rates of OHSS and pregnancy. Results: Oocyte maturation occurred in 95% of women. Highest oocyte yield (121%) was observed following 12.8 nmol/kg kisspeptin-54, which was +69% (confidence interval, −16–153%) greater than following 3.2 nmol/kg. At all doses of kisspeptin-54, biochemical pregnancy, clinical pregnancy, and live birth rates per transfer (n = 51) were 63, 53, and 45%, respectively. Highest pregnancy rates were observed following 9.6 nmol/kg kisspeptin-54 (85, 77, and 62%, respectively). No woman developed moderate, severe, or critical OHSS. Conclusion: Kisspeptin-54 is a promising approach to effectively and safely

  9. Changes in homologous and heterologous gap junction contacts during maturation-inducing hormone-dependent meiotic resumption in ovarian follicles of Atlantic croaker

    Bolamba, D.; Patino, R.; Yoshizaki, G.; Thomas, P.


    Homologous (granulosa cell-granulosa cell) gap junction (GJ) contacts increase in ovarian follicles of Atlantic croaker (Micropogonias undulatus) during the early (first) stage of maturation, but their profile during the second stage [i.e., during maturation-inducing hormone (MIH)-mediated meiotic resumption] is unknown. The profile of homologous GJ contacts during the second stage of maturation in croaker follicles was examined in this study and compared to that of heterologous (granulosa cell-oocyte) GJ, for which changes have been previously documented. Follicles were incubated with human chorionic gonadotropin to induce maturational competence (first stage), and then with MIH to induce meiotic resumption. The follicles were collected for examination immediately before and after different durations of MIH exposure until the oocyte had reached the stage of germinal vesicle breakdown (GVBD; index of meiotic resumption). Ultrathin sections were observed by transmission electron microscopy, and homologous and heterologous GJ contacts were quantified along a 100-??m segment of granulosa cell-zona radiata complex per follicle (three follicles/time/fish, n=3 fish). Relatively high numbers of both types of GJ were observed before and after the first few hours of MIH exposure (up to the stage of oil droplet coalescence). GJ numbers declined during partial yolk globule coalescence (at or near GVBD) and were just under 50% of starting values after the completion of GVBD (Pobservations that GVBD temporally correlates with declining heterologous GJ contacts, and for the first time in teleosts show that there is a parallel decline in homologous GJ. The significance of the changes in homologous and heterologous GJ is uncertain and deserves further study. ?? 2003 Elsevier Science (USA). All rights reserved.

  10. Sulpiride-Induced Hyperprolactinemia in Mature Female Rats: Evidence for Alterations in The Reproductive System, Pituitary and Ovarian Hormones

    Sara Mostafapour


    Full Text Available Background: The prevalence of hyperprolactinemia following administration of conventional antipsychotic drugs requires further investigation. The current study is designed to evaluate the effect of sulpiride (SPD-induced hyperprolactinemia on alterations to ovarian follicular growth, gonadotropins, and ovarian hormones and to analyze the extent of potential problems in mammary glands. Materials and Methods: A total of 40 albino Wistar rats were divided into four groups: control (no treatment, control-sham (0.3 ml olive oil, low dose SPD (20 mg/kg and high dose SPD (40 mg/kg. All compounds were intraperitoneally (IP administered for a period of 28 days. Results: After 28 days, we dissected the rats’ ovarian tissues, uterine horns and mammary glands which were sent for histological analyses. We counted the numbers of normal, atretic follicles and corpora lutea (CL. Serum levels of prolactin (PRL, estradiol, progesterone, follicle stimulating hormone (FSH and luteinizing hormone (LH were evaluated. SPD-administered animals showed sporadic follicular atresia in different sizes associated with higher numbers of CL on the ovaries. The mammary glands exhibited features of galactorrhea. There was remarkable (p<0.05 elevation in SPD-administered animals’ uterine horn endometrium, myometrium and perimetrium thicknesses. The serum levels of PRL and progesterone significantly (p<0.05 increased, while the serum concentration of estradiol, LH and FSH notably (p<0.05 decreased according to the SPD administered dose. No histological and biological changes occurred in control-sham animals. SPD-induced animals had unsuccessful attempts at mating and decreased pregnancy rates. Conclusion: The present findings suggest that SPD-induced disturbances depend on PRL level. In addition, an increased PRL level is largely dependent on the administered doses of SPD.

  11. In-vitro maturation versus IVF with GnRH antagonist for women with polycystic ovary syndrome: treatment outcome and rates of ovarian hyperstimulation syndrome.

    Das, Mausumi; Son, Weon-Young; Buckett, William; Tulandi, Togas; Holzer, Hananel


    In-vitro maturation (IVM) treatment has gained popularity for decreasing the incidence of ovarian hyperstimulation syndrome (OHSS) by eliminating or minimizing the use of gonadotrophins in women with polycystic ovary syndrome (PCOS). Studies have shown that IVF with GnRH-antagonist protocol is associated with a lower incidence of OHSS. Data comparing the relative success of these two treatments is, however, lacking. Treatment outcome and rates of OHSS were compared in patients with PCOS who underwent assisted conception with either IVM or IVF with GnRH-antagonist protocol between 2006 and 2011. The number of oocytes retrieved was higher in the IVM group, whereas the number of mature oocytes, fertilization rate and number of embryos cleaved were comparable. The implantation rate was higher in the IVF group. The clinical pregnancy rates per embryo transfer were not statistically different (IVF: 45.8% versus IVM: 32.4%). The live-birth rate was higher in the IVF group (IVF: 40.7% versus IVM: 23.5%; P = 0.04). Five women developed moderate or severe OHSS in the IVF group, whereas none did in the IVM group. Both IVM and IVF with GnRH-antagonist protocol seem to be effective treatment regimens in women with PCOS, although IVM is associated with a lower risk of OHSS.

  12. Spectrum of Childhood and Adolescent Ovarian Tumors in India: 25 Years Experience at a Single Institution

    Ruchi Rathore


    Full Text Available BACKGROUND: Ovarian tumour in children and adolescent girls form an uncommon but important part of gynaecological malignancies. They account for 1% of all the childhood malignancies and 8% of all abdominal tumours in children. Since the ovarian cysts are thought to arise from mature follicles, these tumours were considered to be infrequent in the paediatric population. AIM: The rarity of this condition prompted us to conduct this study and share our experience on the incidence and clinicopathological features of different ovarian tumours in girls up to 20 years of age observed in last 25 years at a single tertiary care hospital. MATERIAL AND METHODS: This was a retrospective study conducted in the Department of Pathology at a tertiary hospital, Delhi. All ovarian tumours up to the age of 20 years in the past 25 years (1990-2014 were included for the purpose of studying the clinicopathological aspects of ovarian tumours in this age group. Descriptive statistics for prevalence and age-wise prevalence was done. Chi-square test, to find an association between the age, laterality and size with malignancy was performed. RESULTS: We received a total of 1102 cases of ovarian tumours over the period of 25 years  (1990 to 2014, of which 112 (10% cases were seen in girls up to 20 years of age. The mean age of the patients was 15.3 ± 4 years. The most common presenting complaint was pain abdomen (46.4 % There was a statistically significant correlation found between size and malignancy status of tumours in our study (p = 0.00. Of 112 cases of ovarian tumours, 39/112 (34.8% were malignant and 73/112 (65.2% were benign. Mature  cystic teratoma (27.6% was the most common type of benign tumour in this age group and immature teratomas were the most common type of malignant ovarian neoplasms. CONCLUSION: Premenarchal girls with ovarian masses may have varied presentations. Abdominal pain is the most common presenting complaint of young adolescent girls with

  13. Metformin therapy in a hyperandrogenic anovulatory mutant murine model with polycystic ovarian syndrome characteristics improves oocyte maturity during superovulation

    Sabatini Mary E


    Full Text Available Abstract Background Metformin, an oral biguanide traditionally used for the treatment of type 2 diabetes, is widely used for the management of polycystic ovary syndrome (PCOS-related anovulation. Because of the significant prevalence of insulin resistance and glucose intolerance in PCOS patients, and their putative role in ovulatory dysfunction, the use of metformin was touted as a means to improve ovulatory function and reproductive outcomes in PCOS patients. To date, there has been inconsistent evidence to demonstrate a favorable effect of metformin on oocyte quality and competence in women with PCOS. Given the heterogeneous nature of this disorder, we hypothesized that metformin may be beneficial in mice with aberrant metabolic characteristics similar to a significant number of PCOS patients. The aim of this study was to gain insight into the in vitro and in vivo effects of metformin on oocyte development and ovulatory function. Methods We utilized metformin treatment in the transgenic ob/ob and db/db mutant murine models which demonstrate metabolic and reproductive characteristics similar to women with PCOS. Results: Metformin did not improve in vitro oocyte maturation nor did it have an appreciable effect on in vitro granulosa cell luteinization (progesterone production in any genotype studied. Although both mutant strains have evidence of hyperandrogenemia, anovulation, and hyperinsulinemia, only db/db mice treated with metformin had a greater number of mature oocytes and total overall oocytes compared to control. There was no observed impact on body mass, or serum glucose and androgens in any genotype. Conclusions Our data provide evidence to suggest that metformin may optimize ovulatory performance in mice with a specific reproductive and metabolic phenotype shared by women with PCOS. The only obvious difference between the mutant murine models is that the db/db mice have elevated leptin levels raising the questions of whether their

    Naveed, Shah; Qari, Hasina; Banday, Tanveer; Altaf, Asma; Para, Mah


    The purpose of this study was to investigate the actual management of mucinous cystic neoplasm (MCN) of the pancreas. A systematic review was performed in December 2009 by consulting PubMed MEDLINE for publications and matching the key words “pancreatic mucinous cystic neoplasm”, “pancreatic mucinous cystic tumor”, “pancreatic mucinous cystic mass”, “pancreatic cyst” and “pancreatic cystic neoplasm” to identify English language articles describing the diagnosis and treatment of the MCN of the pancreas. In total, 16,322 references ranging from January 1969 to December 2009 were analyzed and 77 articles were identified. No articles published before 1996 were selected because MCNs were not previously considered to be a completely autonomous disease. Definition, epidemiology, anatomopathological findings, clinical presentation, preoperative evaluation, treatment and prognosis were reviewed. MCNs are pancreatic mucin-producing cysts with a distinctive ovarian-type stroma localized in the body-tail of the gland and occurring in middle-aged females. The majority of MCNs are slow growing and asymptomatic. The prevalence of invasive carcinoma varies between 6% and 55%. Preoperative diagnosis depends on a combination of clinical features, tumor markers, computed tomography (CT), magnetic resonance imaging, endoscopic ultrasound with cyst fluid analysis and positron emission tomography-CT. Surgery is indicated for all MCNs.

  1. Uptake and selective partitioning of dietary lipids to ovarian and muscle tissue of maturing female coho salmon, Oncorhynchus kisutch, during secondary oocyte growth.

    Johnson, Ronald B; Kroeger, Eric L; Reichert, William L; Carter, Cameron S; Rust, Michael B


    Female coho salmon, Oncorhynchus kisutch, were fed one of two experimental feeds containing lipids with markedly different stable (13)C isotope signatures during the late cortical alveolus, lipid droplet, and vitellogenesis stages of secondary oocyte growth. Ovarian and muscle lipids fatty acid concentrations were significantly affected by treatment during all three stages of development. Stable (13)C isotope analyses confirmed that dietary lipids were incorporated into both ovarian and muscle lipids during all three stages and revealed that ovarian lipids were more affected than muscle lipids during vitellogenesis. Arachidonic acid (ARA) was incorporated into ovarian lipids at the highest rate of all fatty acids examined with the greatest uptake observed during the cortical alveolus and lipid droplet stages of development. Docosahexaenoic acid (DHA) was incorporated into ovarian lipids at the next highest rate with the greatest uptake observed during the lipid droplet stage of development. The presence of an ovary specific, fatty acid transfer mechanism is proposed. Results from this study demonstrate the ability to greatly alter the fatty acid composition of ovarian lipids through a dietary change during secondary oocyte growth and may be of great interest to producers of farmed salmon and salmon broodstock programs.

    Full Text Available OBJECTIVE : The aim of the study was to know the morphological pattern of benign and malignant ovarian neoplasms and their distribution in different age groups in rural population of India. MATERIAL AND METHODS : A retrospective study of all cases of ovarian neoplasms diagnosed at department of pathology, Maharaja Medical College, Agroha during period of five year (Aug, 07 — Oct.12 was done. The tumors were classified according to WHO classification after thorough examination of slides and their distribution in different age groups was also noted. RESULTS : There were total fifty three cases of ovarian tumors noted during this period. Benign tumors comprised 81.13% and malignant tumors were 18.86%. Surface epithelial tumor emerged as the commonest variety accounting for 60.37%, followed by germ cell tumor (32.07% and sex cord stromal tumors were least common comprising 7.54 % of all ovarian neoplasm. No metastatic tumor or tumors with borderline malignancy were seen. Serous cystadenoma was the commonest tumor (43.39% followed by mature cystic teratoma (30.23%.Among the malignant tumor, malignant germ cell tumor were the commonest type (40%, followed by 30 %of each surface epithelial tumor and sex cord stromal tumor. CONCLUSION : Benign ovarian tumors are seen more common than malignant tumor. Malignant epithelial tumors are seen after the age of 30 years and malignant germ cell tumor are seen below the age of 30 years. Bilaterality is more commonly seen in malignant o varian neoplasm

  3. Expression of cystic fibrosis transmembrane conductance regulator in rat ovary.

    Jin, Lei; Tang, Ruiling


    The protein expression of cystic fibrosis transmembrane conductance regulator (CFTR), a cAMP-activated Cl(-) channel, in ovarian stimulated premature female rat ovary during a cycle of follicle development and corpus luteum formation was investigated. Animals were injected with 10 U pregnant Mare's serum gonadotropin (PMSG) and subsequently 10 U hCG 48 h later. Time-dependent immunohistochemistry and Western blotting experiments were performed before and 24, 48, 72 h after hCG treatment. The immunohistochemistry revealed that administration of PMSG stimulated the CFTR expression in thecal cell layer and granulosa cell layer of mature follicles 48 h post injection, coincident with the PMSG-induced peak in follicular estradiol. However, the expression of CFTR in the granulose lutein cell layer and thecal lutein cell layer was time-dependently reduced following hCG injection, in accordance with the gradually increased progestogen level during luteum corpus formation. Western blotting analysis demonstrated that rat ovarian tissue expressed the special CFTR band at 170 kD. It is concluded that cAMP-dependent Cl(-) channels are involved in regulation of follicle development and luteum formation.

At birth, the ovary contains a finite number of oocytes available for folliculogenesis. This finite number of available oocytes is termed “the ovarian reserve”. The determination of ovarian reserve is important in the assessment and treatment of infertility. As the ovary ages, the ovarian reserve will decline. Infertility affects approximately 15-20% of reproductive aged couples. The most commonly used biomarker assay to assess ovarian reserve is the measurement of follicle stimulating hormone (FSH on day 3 of the menstrual cycle. However, antimüllerian hormone and inhibin-B are other biomarkers of ovarian reserve that are gaining in popularity since they provide direct determination of ovarian status, whereas day 3 FSH is an indirect measurement. This review examines the physical tools and the hormone biomarkers used to evaluate ovarian reserve.

  11. Management of ovarian cysts in infants

    Yan Xue-qiang


    Full Text Available Background: To discuss the experience of diagnosis and treatment of ovarian cyst in infants. Materials and Methods: A retrospective review was conducted on 20 infants who suffered from ovarian cyst. Results: There were no dysplasia ovarian was found in children which were preoperatively diagnosed simplex cyst. Within thirteen children preoperatively detected mixed cystic-solid lesion, six cases ovarian cysts disappeared and two cases underwent poor blood supply in the following time. Conclusion: Adverse effects for ovarian cyst in infants can be prevented by agressive surgical intervention. Harmful effects of ovarian cyst can be prevented by positive surgical intervention despite the diagnostic difficulties in children with clinical symptoms of this condition.

  12. A rare cause for a neonatal cystic abdominal mass.

    Castellani, Christoph; Petnehazy, Thomas; Gürtl-Lackner, Barbara; Saxena, Amulya K


    Intrauterine ovarian torsion is a rare event, but it is a possible cause for unilateral ovarian aplasia. Most commonly the ovary undergoes autolysis after torsion so that no tissue or remnants can be discovered on the involved side. We report a rare case of unilateral intrauterine torsion followed by autoamputation and abdominal reimplantation resulting in an intra-abdominal complex cystic mass with a review of the literature.

    This case report describes a case of concomitant ovarian drilling and retrieval of oocytes using laparoendoscopic single-site surgery and the resultant birth of a healthy infant after transfer of frozen-thawed blastocyst from in vitro matured oocyte in a woman with polycystic ovary syndrome. A 33-year-old woman presented with anovulatory, clomiphene-resistant polycystic ovary syndrome, and 1-year history of infertility. Thirty-seven immature oocytes were retrieved and multiperforation of ovaries was performed at the same time by laparoendoscopic single-site surgery. Twenty-three oocytes reached metaphase II after 24-h culture in in vitro maturation medium, which was followed by intracytoplasmic sperm injection. Eventually, seven embryos were vitrified and spontaneous ovulation was restored after the operation. Although the first single frozen-thawed blastocyst transferred in a natural cycle ended up a biochemical pregnancy, the second frozen-thawed blastocyst transfer resulted in successful pregnancy, followed by live birth of a healthy male infant. © 2014 The Authors.

  15. Genetic analysis of the early natural history of epithelial ovarian carcinoma.

    Bhavana Pothuri

    Full Text Available BACKGROUND: The high mortality rate associated with epithelial ovarian carcinoma (EOC reflects diagnosis commonly at an advanced stage, but improved early detection is hindered by uncertainty as to the histologic origin and early natural history of this malignancy. METHODOLOGY/PRINCIPAL FINDINGS: Here we report combined molecular genetic and morphologic analyses of normal human ovarian tissues and early stage cancers, from both BRCA mutation carriers and the general population, indicating that EOCs frequently arise from dysplastic precursor lesions within epithelial inclusion cysts. In pathologically normal ovaries, molecular evidence of oncogenic stress was observed specifically within epithelial inclusion cysts. To further explore potential very early events in ovarian tumorigenesis, ovarian tissues from women not known to be at high risk for ovarian cancer were subjected to laser catapult microdissection and gene expression profiling. These studies revealed a quasi-neoplastic expression signature in benign ovarian cystic inclusion epithelium compared to surface epithelium, specifically with respect to genes affecting signal transduction, cell cycle control, and mitotic spindle formation. Consistent with this gene expression profile, a significantly higher cell proliferation index (increased cell proliferation and decreased apoptosis was observed in histopathologically normal ovarian cystic compared to surface epithelium. Furthermore, aneuploidy was frequently identified in normal ovarian cystic epithelium but not in surface epithelium. CONCLUSIONS/SIGNIFICANCE: Together, these data indicate that EOC frequently arises in ovarian cystic inclusions, is preceded by an identifiable dysplastic precursor lesion, and that increased cell proliferation, decreased apoptosis, and aneuploidy are likely to represent very early aberrations in ovarian tumorigenesis.

  16. [Primary Pelvic Cystic Echinococcosis].

    Yaman, İsmail; İnceboz, Ümit; İnceboz, Tonay; Keyik, Bahar; Uzgören, Engin


    Cystic echinococcosis caused by Echinococcus granulosus is still an important health problem in endemic areas. Cystic echinococcosis may involve different organs or areas with the most common sites being the liver and the lungs. Pelvic involvement has previously been reported and was mainly accepted as secondary to cystic echinococcosis in other organs, isolated pelvic involvement is very rare. In this case report, we aimed to present the case with pelvic cystic mass that was finally diagnosed with isolated pelvic cystic echinococcosis in and after the operation, and we would like to draw attention to include "cystic echinococcosis" in the differential diagnosis of pelvic masses.

  18. Ovarian teratoma displaying a wide variety of tissue components in a broiler chicken (Gallus Domesticus: morphological heterogeneity of pluripotential germ cell during tumorigenesis

    S. Ohfuji


    Full Text Available Spontaneous ovarian teratoma was found in a seven-week-old female Chunky broiler chicken that was slaughtered for food. On post-mortem inspection, a spherical tumor mass attaching to a juvenile ovary was found in the abdominal cavity. Histopathologically, the tumor was comprised of immature mesenchymal stroma and a variety of mature tissue elements of mesodermal and ectodermal origin. In addition, there were multiple indistinguishable tissue elements, which showed no malignant cytological features but were unidentifiable as to corresponding embryological layer of origin. These heterogeneous teratoma tissues consisted of a variety of glandular, cystic, duct-like, and tubular structures, some of which exhibited a lining by a mixture of both keratinizing/non-keratinizing stratified squamous epithelial cells and cuboidal/columnar epithelial cells. The ovarian tetatoma was considered a benign and congenital one. The highly diverse differentiation of the teratoma might have manifested a morphological aspect of intrinsic character of the pluripotential germ cells during tumorigenesis.

  19. Effects of shortened photoperiod on gonadotropin-releasing hormone, gonadotropin, and vitellogenin gene expression associated with ovarian maturation in rainbow trout.

    Choi, Sungchang; Lee, Cheul Ho; Park, Woodong; Kim, Dae-Jung; Sohn, Young Chang


    Reproductive activities of salmonids are synchronized by changes in photoperiod, which control the endocrine system via the brain-pituitary-gonadal axis. Gonadotropin-releasing hormone (GnRH) in the brain regulates synthesis and release of the pituitary gonadotropins (GTHs; FSH and LH). FSH and LH in turn stimulate the production of sex steroids for oocyte growth and maturation-Inducing steroid hormones for oocyte maturation and ovulation, respectively, in female salmonids. To clarify effects of long-term photoperiod manipulations on the reproductive activity of salmonids from early recrudescence to ovulation, we Investigated the gene expression profiles of GnRH, GTHs, and vitellogenin (VTG), and plasma sex steroids in female rainbow trout (Oncorhynchus mykiss). In addition, the percentages of eyed embryos and hatched alevins were examined together with the number of ovulated eggs to evaluate the effects of photoperiod regimes on egg quality. During late summer, the mRNA levels of GnRHs, GTHalpha, and LHbeta, and the plasma level of a maturational steroid (17alpha,20beta-dihydroxy-4-pregnen-3-one; 17,20beta-P) were significantly elevated by a gradually shortened photoperiod under constant temperature, in accordance with accelerated sexual maturation. The percentages of eyed embryos and hatched alevins from fish ovulated in August were comparable to those of control fish observed in December. These results clearly indicate that syntheses of GnRHs, LH, VTG, and 17,20beta-P are effectively accelerated by a programmed long-short photoperiod regime in early recrudescent female rainbow trout, without a marked deterioration in egg quality.

  20. Cystic fibrosis

    Radlović Nedeljko


    Full Text Available Cystic fibrosis (CF is a multisystemic autosomal recessive disease caused by a defect in the expression of CFTR protein, i.e. chloride channel present in the apical membrane of respiratory, digestive, reproductive and sweat glands epithelium. It primarily occurs in the Caucasians, while being considerably or exceptionally rare in persons of other races. Absence, deficit or structural and functional abnormalities of CFTR protein lead to mucosal hyperconcentration in the respiratory, digestive and reproductive systems and malabsorption of chloride and sodium in the sweat glands. Thus, the clinical features of patients’ with CF are predominated by respiratory, digestive and reproductive disorders, as well as the tendency to dehydration in the condition of increased sweating. Beside genotype variations, the degree of disease manifestation is also essentially influenced by various exogenous factors, such as the frequency and severity of respiratory infections, the level of aero-pollution, quality of immunoprophylaxis, patients’ nutritional condition and other. Chloride concentration of over 60 mmol/L in sweat, a high level of immunoreactive chymotrypsinogen in blood and the verification of homozygous mutation of CFTR gene are the basic methods in the diagnostics of the disease. CF belongs to the group of severe and complex chronic diseases, and therefore requires multidisciplinary therapeutic approach. Owing to the improvement of healthcare provision, most patients with CF now survive into adulthood. In addition, their quality of life is also considerably improved.

    Cystic fibrosis is an autosomal recessive genetic disease. Among Caucasians, it is the most common cause of pulmonary insufficiency during the first three decades of life. The prevalence of cystic fibrosis varies according to ethnic origin: it is common among Caucasians but rare among Asians. We report a case in which cystic fibrosis with bronchiectasis and hyperaeration was revealed by high-resolution CT, and mutation of the cystic fibrosis conductance transmembrane regulator gene (CFTR) by DNA analysis.

  3. Differential points of mediastinal cystic lesion in chest computed tomography

    Lee, Seung Jin; Baek, Jang Mi; Song, Jang Hyeon; Seon, Hyun Ju [Dept. of Radiology, Chonnam National University Hospital, Gwangju (Korea, Republic of); Kim, Yun Hyeon [Dept. of Radiology, Chonnam National University Hwasun Hospital, Hwasun (Korea, Republic of)


    To find differential diagnostic imaging findings of mediastinal cystic lesions in chest computed tomography. We retrospectively reviewed imaging findings of 70 patients with histopathologically proven mediastinal cystic lesions. They were 33 male and 37 female patients. Among 70 cases, 49 cases were in the anterior mediastinum, 12 cases were in the middle mediastinum, and 9 cases were in the posterior mediastinum. 19 patients had symptoms. Chest discomfort was the most common symptom. When the cystic lesion was located in the anterior mediastinum, and unilocular, the possibility of thymic cyst was the most likely (p < 0.0027). When the cystic lesion was located in the anterior mediastinum and was multilocular with a relatively thick wall, the possibility of a mature cystic teratoma was the most likely (p < 0.001). When the lesion was a high attenuation cystic lesion located around the air-way, the possibility of a bronchogenic cyst was the most likely (p < 0.001). Chest CT gives information about the location, loculation, wall thickness and internal attenuation of mediastinal cystic lesions. And certain details seen on CT imaging can help with the correct diagnosis, especially in the cases of thymic cyst, mature cystic teratoma and bronchogenic cyst.

  4. Ovarian response in consecutive cycles of ovarian stimulation in normally ovulating women.

    Ahmed Ebbiary, N A; Morgan, C; Martin, K; Afnan, M; Newton, J R


    Ovarian stimulation combined with intra-uterine insemination (IUI) is an effective treatment of non-tubal infertility but most women undergo several cycles of treatment to achieve a pregnancy. This prospective study was designed to assess the consistency (or variation) of ovarian responses and the effect of various ovarian stimulation protocols on this consistency in consecutive cycles of ovarian stimulation and IUI in women with non-ovulatory infertility. A total of 86 regularly menstruating ovulating patients each completed three to six cycles of ovarian stimulation and IUI (n = 347 cycles). Ovarian stimulation was achieved by sequential clomiphene citrate/human menopausal gonadotrophin (HMG), HMG-only or combined gonadotrophin-releasing hormone analogue--HMG protocols in 33, 29 and 24 patients respectively, and each patient used the same protocol consistently throughout the study. Standard methods were used to monitor ovarian response and to perform IUI. Using each patient as her own control, repeated measurements analysis of variance revealed consistency of ovarian response in consecutive ovarian stimulation cycles, as shown by the number and mean diameter of maturing pre-ovulatory follicles, peak plasma oestradiol, duration of stimulation and mean HMG requirements. This consistency existed using any of the ovarian stimulation protocols. We conclude that regularly menstruating and ovulating women are likely to have similar ovarian responses in consecutive cycles of ovarian stimulation and IUI if the same ovarian stimulation protocol is used consistently.(ABSTRACT TRUNCATED AT 250 WORDS)

  5. How to control the synchronization of oocyte nuclear and cytoplasmic maturation in the controlled ovarian hyperstimulation cycles%超排卵周期如何控制卵母细胞胞核与胞质的同步成熟

    王玢; 孙海翔


    Complete maturation of oocyte includes both nuclear and cytoplasmic maturation. At present, expulsion of the first polar body is known as the marker of oocyte nuclear maturation. Expansions of granulose cells and oocyte-corona-cumulus complex synchronize with the maturation of oocyte nuclei following the maturation of oocyte in the natural cycle. However, the expansion of oocyte-corona-cumulus complex and nuclear maturation are not synchronized due to disturbance of exogenous gonadotropins in controlled ovarian hyperstimulation (COH) cycles. The status of expansion of oocyte-corona-cumulus complex can not be used to estimate the maturation of oocyte maturation in COH cycles. The morphology characteristics of oocyte, migration of cortical granules and relative factors such as GDF9 , BMP15 etc. can not monitor cytoplasmic maturation fast and directly. In COH cycles, fertilization rate, cleavage rate, pregnancy rate and implantation rate display a rising trend along with the increased proportion of matured oocytes. The rate of available embryos from the oocytes with large follicular diameter is higher than that from the oocytes with small follicular diameter. Oocyte maturation rate and fertilization rate decrease but the fragments in embryos increase along with the reduction of follicular diameter. However, the diameter of dominant follicle does not reflect overall situation of follicular development in ovary. A group of follicles on behalf of the development synchronization of total follicles are named as "object follicles" in progress of COH. The "object follicles" determine the trigger time of hCG. In vitro investigations of mouse embryos also confirm that cultured oocyte in vitro for some time after hCG injection plays an important role in the maturation of oocyte nuclei and cytoplasm, where higher proportion and quicker speed of pronuclei development can be acquired after fertilization or artificial activation. High-quality embryo rate and pregnancy rate increase

  6. Bilateral ovarian cystadenoma in a geriatric African elephant (Loxodonta africana).

    Hoby, Stefan; Aloisio, Fabio; Schumacher, Vanessa L


    A 59-yr-old, captive female African elephant (Loxodonta africana) died of a cardiovascular collapse. Necropsy revealed bilateral replacement of the ovarian tissue by multiple cystic formations of up to 10 cm in diameter. The cysts were thin walled and filled with clear watery fluid. Smaller solid masses with an irregular surface projected from the wall of a few of the cysts. Histologically, the cystic structures were characterized by a single layer of well-differentiated cuboidal epithelial cells resting on a basement membrane. Occasionally the cysts contained nodular proliferations of single-layered, well-differentiated cuboidal epithelial cells forming anastomosing tubules and occasional papillary projections. The ovarian neoplasia was diagnosed as a bilateral multilocular serous ovarian cystadenoma. The nulliparous status and the advanced age may have contributed to the ovarian pathology.

  9. The 9-d CIDR-PG protocol II: Characterization of endocrine parameters, ovarian dynamics, and pregnancy rates to fixed-time AI following use of long-term CIDR-based estrus synchronization among mature beef cows.

    Thomas, J M; Locke, J W C; Bishop, B E; Abel, J M; Ellersieck, M R; Poock, S E; Smith, M F; Patterson, D J


    An experiment was designed to evaluate endocrine parameters, ovarian dynamics, and pregnancy rates to fixed-time artificial insemination (FTAI) following the 9-d CIDR-PG protocol in comparison to the 14-d CIDR-PG protocol. While both are long-term protocols using CIDR treatment for presynchronization, the 9-d CIDR-PG protocol differs from the 14-d CIDR-PG protocol in that prostaglandin F2α (PG) is administered at CIDR insertion and removal to facilitate a decreased length of progestin treatment and potentially enhance response to the presynchronization treatment. Estrus was synchronized for 393 mature beef cows across five locations. Treatments were represented in each location, and cows within each location were randomly assigned to one of the two protocols based on age, days postpartum (DPP), and body condition score (BCS). Cows assigned to the 14-d CIDR-PG treatment received a CIDR insert (1.38 g progesterone) on Day 0 with removal of CIDR on Day 14, and 25 mg PG 16 d after CIDR removal on Day 30. Cows assigned the 9-d CIDR-PG treatment received 25 mg PG and a CIDR insert (1.38 g progesterone) on Day 5; 25 mg PG and removal of CIDR on Day 14; and 25 mg PG 16 d after CIDR removal on Day 30. In both treatments, cows received FTAI on Day 33, 72 h after PG. All cows were administered 100 μg gonadotropin-releasing hormone (GnRH) concurrent with insemination. For a subset of animals in each treatment, ovarian ultrasound was performed and blood samples were collected for determination of serum estradiol concentrations at CIDR removal, PG administration, and FTAI. Protocols were compared on the basis of estrous response and pregnancy rate resulting from FTAI. Serum estradiol concentrations, follicle size, and estrous response did not differ based on treatment. However, cows assigned to the 9-d CIDR-PG protocol tended to achieve greater FTAI pregnancy rates than cows assigned to the 14-d CIDR-PG protocol (62% versus 52%; P = 0.07). Across treatments

  10. Hyperbilirubinemia associated with a cystic abdominal mass in a 6-week-old girl: case report.

    Schleef, J; Oleszuk-Raschke, K; Morcate, J J; Steinau, G; Willital, G H


    Abdominal cysts in girls are frequently observed by abdominal ultrasound (US) and are usually ovarian. In this case a cystic structure located in the right abdomen was seen in a female newborn without symptoms and was initially described as a possible ovarian cyst. Frequent US examinations showed an increase in volume and diameter, and temporary, recurring episodes of hyperbilirubinemia were observed. The US scans showed no relationship to the biliary tree. During a diagnostic laparoscopy, a cystic structure attached to the pyloric region was seen. A laparotomy revealed a cystic duplication of the stomach, which could be resected completely. The finding is discussed emphasizing the importance of clinical findings and diagnostic methods in the diagnosis and management of abdominal cystic masses in females.

    This paper describes the imaging features of ovarian metastases from adenocarcinoma of the colon in adolescent females. We reviewed retrospectively abdominal and pelvic computed tomographic and pelvic ultrasound examinations, histologic slices, and clinical charts of six adolescent females with ovarian metastases secondary to adenocarcinoma of the colon. One patient had ovarian metastasis at presentation and was presumed to have a primary ovarian tumor. The ovarian metastases were either solid (n = 3), complex with both solid and cystic components (n = 2), or multilocular cysts (n = 1). The ovarian lesions were large, ranging from 6 cm to 18 cm in diameter. Colorectal carcinoma in adolescent females is frequently associated with ovarian metastases. One imaging characteristic differs in adult and adolescent ovarian metastases, although they do have features in common: in adolescents, a smaller proportion of colorectal ovarian metastases are multicystic (17%) compared with the adult series (45%). These lesions are frequently large and may be complex, multicystic, or solid. Although it is a rare disease, the differential dignosis of adnexal masses in adolescent females should include ovarian metastases from adenocarcinoma of the colon. (orig.)

  18. Multicystic Benign Cystic Mesothelioma Presenting as a Pelvic Mass

    Mazdak Momeni


    Full Text Available Background. Benign cystic mesothelioma (BCM is a rare tumor that arises from the abdominal peritoneum with a predilection to the pelvic peritoneum. For this reason, it can often mimic gynecologic malignancies. Case. A 47-year-old perimenopausal female presented reporting several weeks of abdominal distention associated with abdominal tenderness and constipation. Computed tomography revealed a 24 cm multiloculated pelvic mass, and tumor markers were notable for an elevated CA-125. The patient was taken to the operating room for an exploratory laparotomy, total abdominal hysterectomy, bilateral salpingoophorectomy, and removal of pelvic mass. Final pathologic evaluation revealed a benign cystic mesothelioma. Conclusion. Classically these tumors present as large multicystic masses with thin-walled septations and on preoperative evaluation BCM can mimic many different disease entities including ovarian malignancies and cystic lymphangioma. Often diagnosis can only be made at time of surgery.

    Kim, Yong Il; Kim, Seok Ki; Lee, Jeong Won; Lee, Sang Mi; Kim, Tae Sung [National Cancer Center, Goyang (Korea, Republic of)


    A 32-year-old female who suffered from abdominal pain underwent {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the diagnostic workup of pelvic mass lesions. Cystic mass lesions in the bilateral ovaries showed wall thickening and intense hypermetabolism along the rim. In addition, multifocal intense hypermetabolic lymphadenopathies were seen in the left paraaortic lymph node (LN), aortocaval LN, and both common iliac LNs. We interpreted these findings as bilateral ovarian cancer with retroperitoneal metastatic lymphadenopathies rather than endometriosis with reactive lymphadenopathies rather than endometriosis with reactive lymphadenopathies. However, Histopathological examination confirmed the ovarian mass lesions as tubo-ovarian abscesses. We report a case that even if simultaneous hypermetabolic retroperitoneal LNs are seen, intense hypermetabolic lesions in both ovaries can be in consequence of inflammatory change

  2. Ovarian Cancer Stroma: Pathophysiology and the Roles in Cancer Development

    Furuya, Mitsuko [Department of Pathology, Yokohama City University Graduate School of Medicine, Yokohama 236-0004 (Japan)


    Ovarian cancer represents one of the cancers with the worst prognostic in adult women. More than half of the patients who present with clinical signs such as abdominal bloating and a feeling of fullness already show advanced stages. The majority of ovarian cancers grow as cystic masses, and cancer cells easily spread into the pelvic cavity once the cysts rupture or leak. When the ovarian cancer cells disseminate into the peritoneal cavity, metastatic nests may grow in the cul-de-sac, and in more advanced stages, the peritoneal surfaces of the upper abdomen become the next largest soil for cancer progression. Ascites is also produced frequently in ovarian cancers, which facilitates distant metastasis. Clinicopathologic, epidemiologic and molecular studies on ovarian cancers have improved our understanding and therapeutic approaches, but still further efforts are required to reduce the risks in the patients who are predisposed to this lethal disease and the mortality of the patients in advanced stages. Among various molecules involved in ovarian carcinogenesis, special genes such as TP53, BRCA1 and BRCA2 have been well investigated. These genes are widely accepted as the predisposing factors that trigger malignant transformation of the epithelial cells of the ovary. In addition, adnexal inflammatory conditions such as chronic salpingitis and ovarian endometriosis have been great research interests in the context of carcinogenic background of ovarian cancers. In this review, I discuss the roles of stromal cells and inflammatory factors in the carcinogenesis and progression of ovarian cancers.

    Zhang, Ji; Chen, Zheng-he; Wang, Zi-feng; Sun, Peng; Jin, Jie-tian; Zhang, Xiang-heng; Zhao, Yi-ying; Wang, Jian; Mou, Yong-gao; Chen, Zhong-ping


    Abstract Cystic spinal meningioma (CSM) is an uncommon meningioma variant. Extradural CSMs are particularly rare and difficult to distinguish from other intraaxial tumors. This study presents a case of a 36-year-old woman with intraspinal extradual CSM at the thoracolumbar spine. She experienced persistent weakness, progressive numbness, and sensory disturbance in the right lower limb. Magnetic resonance imaging (MRI) of the patient revealed an irregular cystic mass at the thoracic 11 to lumbar 3 levels dorsally. This case was misdiagnosed as other neoplasms prior to surgery because of the atypical radiographic features and location of the tumor. Extradural CSMs should be considered in the differential diagnosis of intraspinal extradural cystic neoplasms. Complete removal of cystic wall provides an optimal outcome, rendering the lesion curable. PMID:26986119

  5. Cystic endometrial hyperplasia and pyometra in three captive African hunting dogs (Lycaon pictus).

    Jankowski, Gwen; Adkesson, Michael J; Langan, Jennifer N; Haskins, Samantha; Landolfi, Jamie


    Pyometra and cystic endometrial hyperplasia are common in domestic canids and are suspected to develop as a consequence of elevated progesterone levels. Reports of uterine pathology in exotic canids are limited, with some speculating of association with contraception. This report describes pyometra, cystic endometrial hyperplasia, and ovariohysterectomy in three African hunting dogs (Lycaon pictus). Ovarian corpora lutea were detected in two of the dogs, suggesting endogenous progesterone production. One dog had a uterine adenocarcinoma and two had ovarian granulosa cell tumors. Clinical signs included anorexia, lethargy, vulvar discharge, polyuria, polydipsia, and abdominal distention. Diagnosis was based on clinical signs, physical examination, bloodwork, radiography, and ultrasonography, with confirmation through histopathologic evaluation of tissues. Cystic endometrial hyperplasia, pyometra, and uterine neoplasia have rarely been diagnosed in exotic canids; however, they should be considered as differential diagnoses in intact bitches that present with suspected reproductive disease.

  7. Ultrasound Imaging of Cystic Nephroma

    Federico Greco


    Full Text Available Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term “cystic nephroma” represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable mass or nonspecific symptoms such as abdominal pain, hematuria, and urinary tract infections. In this review, we summarize the ultrasound imaging features of cystic nephroma and describe the characteristics of the most common renal cystic lesions and the differential diagnosis of cystic nephroma with other renal cystic lesions.

  8. Insulin-like growth factor binding protein 2 promotes ovarian cancer cell invasion

    Liu Jinsong


    Full Text Available Abstract Background Insulin-like growth factor binding protein 2 (IGFBP2 is overexpressed in ovarian malignant tissues and in the serum and cystic fluid of ovarian cancer patients, suggesting an important role of IGFBP2 in the biology of ovarian cancer. The purpose of this study was to assess the role of increased IGFBP2 in ovarian cancer cells. Results Using western blotting and tissue microarray analyses, we showed that IGFBP2 was frequently overexpressed in ovarian carcinomas compared with normal ovarian tissues. Furthermore, IGFBP2 was significantly overexpressed in invasive serous ovarian carcinomas compared with borderline serous ovarian tumors. To test whether increased IGFBP2 contributes to the highly invasive nature of ovarian cancer cells, we generated IGFBP2-overexpressing cells from an SKOV3 ovarian cancer cell line, which has a very low level of endogenous IGFBP2. A Matrigel invasion assay showed that these IGFBP2-overexpressing cells were more invasive than the control cells. We then designed small interference RNA (siRNA molecules that attenuated IGFBP2 expression in PA-1 ovarian cancer cells, which have a high level of endogenous IGFBP2. The Matrigel invasion assay showed that the attenuation of IGFBP2 expression indeed decreased the invasiveness of PA-1 cells. Conclusions We therefore showed that IGFBP2 enhances the invasion capacity of ovarian cancer cells. Blockage of IGFBP2 may thus constitute a viable strategy for targeted cancer therapy.

  9. Multiple cystic lung disease

    Flavia Angélica Ferreira Francisco


    Full Text Available Multiple cystic lung disease represents a diverse group of uncommon disorders that can present a diagnostic challenge due to the increasing number of diseases associated with this presentation. High-resolution computed tomography of the chest helps to define the morphological aspects and distribution of lung cysts, as well as associated findings. The combination of appearance upon imaging and clinical features, together with extrapulmonary manifestations, when present, permits confident and accurate diagnosis of the majority of these diseases without recourse to open-lung biopsy. The main diseases in this group that are discussed in this review are lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis and folliculin gene-associated syndrome (Birt–Hogg–Dubé; other rare causes of cystic lung disease, including cystic metastasis of sarcoma, are also discussed. Disease progression is unpredictable, and understanding of the complications of cystic lung disease and their appearance during evolution of the disease are essential for management. Correlation of disease evolution and clinical context with chest imaging findings provides important clues for defining the underlying nature of cystic lung disease, and guides diagnostic evaluation and management.

  10. Retroperitoneal Cystic Lymphangioma

    Ş.Sevil Altunrende


    Full Text Available Abdominal cystic lymphangioma is a rare, benign, congenital tumor. It is an developmental abnormality of the lymphatic system. Males are relatively more affected and 90% of the cases are under 5 years of age. Multilocular cystic lesion with septations is seen on abdominal ultrasonography. As echogenicity can vary depending on the content of the cyst like cellular debris, hemorrhage or chylous, liquid-liquid or fat-liquid levels can be observed. Definitive treatment is total excision. Cyst aspiration is not an effective method and nearly always ends with recurrence. Computerized tomography and magnetic resonance imaging findings of sonographically detected retroperitoneal cystic lymphangioma in a newborn girl with abdominal distention are discussed in this paper.

    Domínguez-Pérez, S T; Baeza-Herrera, C; Villalobos-Castillejos, A; González-Mateos, T; Aguilar-Venegas, M


    Omental, mesenteric and retroperitoneal cystic masses are very rare in pediatric population. They usually present as asymptomatic abdominal tumors and only occasionally a preoperative diagnosis is made. We presented 4 cases presented to our hospital during a 2-year period. All patients were male with an age ranged from 5 months to 7 years. Three patients had previous diagnosis of cystic mass by abdominal ultrasound. Three patients presented with acute abdomen and one patient with bowel obstruction. All patients underwent successful resection of the mass with no perioperative mortality.

  12. Ovarian adenosarcoma simulating a simple cyst in a young patient

    Leonardo Gomes da Fonseca


    Full Text Available Müllerian adenosarcoma is a rare, mixed tumor that can occur throughout the female genital tract, but is most commonly found in the uterus. Ovarian adenosarcoma is rarer and has a poorer prognosis than uterine adenosarcoma. Data on the clinicopathological features of ovarian adenosarcoma are limited, and, due to its rarity, the management is controversial. The authors report a case of a 25-year-old patient who presented with recurrent abdominal pain. Sonography and laparotomy showed an ovarian cyst, and pathologic examination confirmed the diagnosis of cystic low-grade adenosarcoma. The patient remains free of recurrence 6 months after diagnosis. The authors call attention to the differential diagnosis of ovarian masses, especially in young patients, and to the lack of evidence on the management of this neoplasm in the literature.

  13. [Treatment of Cystic Fibrosis with CFTR Modulators].

    Tümmler, B


    Personalized medicine promises that medical decisions, practices and products are tailored to the individual patient. Cystic fibrosis, an inherited disorder of chloride and bicarbonate transport in exocrine glands, is the first successful example of customized drug development for mutation-specific therapy. There are two classes of CFTR modulators: potentiators that increase the activity of CFTR at the cell surface, and correctors that either promote the read-through of nonsense mutations or facilitate the translation, folding, maturation and trafficking of mutant CFTR to the cell surface. The potentiator ivacaftor and the corrector lumacaftor are approved in Germany for the treatment of people with cystic fibrosis who carry a gating mutation such as p.Gly551Asp or who are homozygous for the most common mutation p.Phe508del, respectively. This report provides an overview of the basic defect in cystic fibrosis, the population genetics of CFTR mutations in Germany and the bioassays to assess CFTR function in humans together with the major achievements of preclinical research and clinical trials to bring CFTR modulators to the clinic. Some practical information on the use of ivacaftor and lumacaftor in daily practice and an update on pitfalls, challenges and novel strategies of bench-to-bedside development of CFTR modulators are also provided.

  16. Pediatric Ovarian Growing Teratoma Syndrome

    Rebecca M. Rentea


    Full Text Available Ovarian immature teratoma is a germ cell tumor that comprises less than 1% of ovarian cancers and is treated with surgical debulking and chemotherapy depending on stage. Growing teratoma syndrome (GTS is the phenomenon of the growth of mature teratoma elements with normal tumor markers during or following chemotherapy for treatment of a malignant germ cell tumor. These tumors are associated with significant morbidity and mortality due to invasive and compressive growth as well as potential for malignant transformation. Current treatment modality is surgical resection. We discuss a 12-year-old female who presented following resection of a pure ovarian immature teratoma (grade 3, FIGO stage IIIC. Following chemotherapy and resection of a pelvic/liver recurrence demonstrating mature teratoma, she underwent molecular genetics based chemotherapeutic treatment. No standardized management protocol has been established for the treatment of GTS. The effect of chemotherapeutic agents for decreasing the volume of and prevention of expansion is unknown. We review in detail the history, diagnostic algorithm, and previous reported pediatric cases as well as treatment options for pediatric patients with GTS.

  18. Human oocyte maturation in vitro.

    Coticchio, Giovanni; Dal-Canto, Mariabeatrice; Guglielmo, Maria-Cristina; Mignini-Renzini, Mario; Fadini, Rubens


    Oocytes from medium-sized antral follicles have already completed their growth phase and, if released from the follicular environment and cultured in vitro, are able to resume the meiotic process and mature. However, in vitro maturation (IVM) does not entirely support all the nuclear and cytoplasmic changes that occur physiologically as an effect of the ovulatory stimulus. Regardless, oocyte IVM is widely applied for the breeding of agriculturally important species. In assisted reproduction technology, IVM has been proposed as an alternative treatment to circumvent the drawbacks of standard ovarian stimulation regimens. Initially introduced to eliminate the risks of ovarian hyperstimulation syndrome afflicting women presenting with polycystic ovaries, subsequently IVM has been suggested to represent an additional approach suitable also for normovulatory patients. So far, in children born from IVM cycles, no doubts of an increased incidence of congenital abnormalities have been raised. Many more births would be achieved if novel IVM systems, currently dominated by empiricism, could be conceived according to more physiological criteria. Recent findings shedding new light on the control of meiotic progression, the support of cumulus cells to the oocyte cellular reorganization occurring during maturation, and the modulation of the stimulus that promotes oocyte maturation downstream the mid-cycle gonadotropin signal are likely to provide crucial hints for the development of more efficient IVM systems.

  19. Maternal synchronization of gestational length and lung maturation.

    Valérie Besnard

    Full Text Available Among all mammals, fetal growth and organ maturation must be precisely synchronized with gestational length to optimize survival at birth. Lack of pulmonary maturation is the major cause of infant mortality in preterm birth. Whether fetal or maternal genotypes influence the close relationship between the length of gestation and lung function at birth is unknown. Structural and biochemical indicators of pulmonary maturity were measured in two mouse strains whose gestational length differed by one day. Shorter gestation in C57BL/6J mice was associated with advanced morphological and biochemical pulmonary development and better perinatal survival when compared to A/J pups born prematurely. After ovarian transplantation, A/J pups were born early in C57BL/6J dams and survived after birth, consistent with maternal control gestational length. Expression of genes critical for perinatal lung function was assessed in A/J pups born after ovarian transfer. A subset of mRNAs important for perinatal respiratory adaptation was selectively induced in the A/J pups born after ovarian transfer. mRNAs precociously induced after ovarian transfer indicated an important role for the transcription factors C/EBPα and CREB in maternally induced lung maturation. We conclude that fetal lung maturation is determined by both fetal and maternal genotypes. Ovarian transfer experiments demonstrated that maternal genotype determines the timing of birth and can influence fetal lung growth and maturation to ensure perinatal survival.

  20. Molecular chaperones as targets to circumvent the CFTR defect in cystic fibrosis

    Rebecca A Chanoux


    Full Text Available Cystic Fibrosis (CF is the most common autosomal recessive lethal disorder among Caucasian populations. CF results from mutations and resulting dysfunction of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR. CFTR is a cyclic AMP-dependent chloride channel that is localized to the apical membrane in epithelial cells where it plays a key role in salt and water homeostasis. An intricate network of molecular chaperone proteins regulates CFTR’s proper maturation and trafficking to the apical membrane. Understanding and manipulation of this network may lead to therapeutics for Cystic Fibrosis in cases where mutant CFTR has aberrant trafficking.

    Luis Ortigosa


    Full Text Available Cystic fibrosis (CF is one of the most frequent inherited mortal diseases in Caucasian population. Dysfunction in exocrine glands is described in CF patients, with severe pancreatic insufficiency and chronic lung disease. CF is inherited as an autosomal recessive disorder. More than 1000 disease-associated mutations in the cystic fibrosis transmembrane conductance regulator (CFTR gene have been described. DF508 mutation is the most common mutation in the CF gen. Diagnosis in CF is based on clinical and laboratory tests findings. Meconial ileus, CF in other relatives, chronic lung disease, congenital absence of the vas deferens with azoospermia are among other clinical findings, main criteria in CF patients. Two positive results in sweat chloride test , or demonstration in nasal epithelial ionic transport alteration (nasal potential difference and identification of two CF mutations in the patient are laboratory findings in CF.

  3. Abdominal cystic lymphangioma mimicking appendicitis.

    Wake, Sarah; Abhyankar, Aruna; Hutton, Kim


    A cystic lymphangioma arising within the abdomen is a rare entity in children. It may present with an abdominal mass and symptoms of abdominal pain, vomiting, and anorexia. These nonspecific clinical symptoms are often attributed to more common acute pediatric conditions. In this report, we describe two pediatric cases of intra-abdominal cystic lymphangioma that were initially diagnosed and treated as appendicitis. True diagnosis was only achieved on surgical excision and pathological investigation of cystic material.

  4. [News in cystic fibrosis].

    Delaisi, B


    The improvement over the last two decades in the treatment of cystic fibrosis led to an increase in life expectancy approaching 40 years at birth. Logically, the population of adult patients has been increasing and is currently 50% of patients followed in France. These therapeutic advances have justified the establishment in 2003 of a generalized neonatal screening for cystic fibrosis. The latest data of this screening show an incidence of CF of 1/5359 live births, far below the incidence of 1/2500 which was widely accepted twenty years ago. The performance of this screening is currently based on the dosage of trypsin immuno reactive, followed in case of exceeding the threshold of a search of the 30 most common mutations, can detect around 96% of 150 to 200 CF cases every year. Therefore, the possibility of a false negative of the screening cannot be excluded and evocative symptoms of cystic fibrosis, even for children born after 2003, will lead to prescribe a sweat test. While treatments available so far goal consequences of cystic fibrosis, a new therapeutic class to correct the functional defect of the mutated protein, called CFTR modulators, is emerging. Ivacaftor, leader of this new class, belonging to the category of "CFTR potentiator" got its access on the market in September 2012 for patients carrying the G551D mutation. New other molecules, named "CFTR correctors" which can have synergistic effect with ivacaftor and concern patients carrying the most common mutation--DF 508--are under development. Copyright © 2013.

    This unit describes a recommended approach to identifying causal genetic variants in an individual suspected of having cystic fibrosis. An introduction to the genetics and clinical presentation of cystic fibrosis is initially presented, followed by a description of the two main strategies used in the molecular diagnosis of cystic fibrosis: (1) an initial targeted variant panel used to detect only the most common cystic fibrosis-causing variants in the CFTR gene, and (2) sequencing of the entire coding region of the CFTR gene to detect additional rare causal CFTR variants. Finally, the unit concludes with a discussion regarding the analytic and clinical validity of these approaches.

  8. Premature ovarian failure

    Vujović Svetlana


    Full Text Available Premature ovarian failure (POF is the occurrence of hypergonadotropic hypoestrogenic amenorrhea in women under the age of forty years. It is idiopathic in 74-90% patients. Known cases can be divided into primary and secondary POF. In primary POF genetic aberrations can involve the X chromosome (monosomy, trisomy, translocations, deletions or autosomes. Genetic mechanisms include reduced gene dosage and non-specific chromosome effects impairing meiosis, decreasing the pool of primordial follicles and increasing atresia due to apoptosis or failure of follicle maturation. Autoimmune ovarian damage is caused by alteration of T-cell subsets and T-cell mediated injury, increase of autoantibody producing B-cells, a low number of effector/cytotoxic lymphocyte, which decreases the number and activity of natural killer cells. Bilateral oophorectomy, chemotherapy, radiotherapy and infections cause the secondary POF. Symptoms of POF include irritability, nervousness, loss of libido, depression, lack of concentration, hot flushes, weight gaining, dry skin, vaginal dryness, frequent infections etc. The diagnosis is confirmed by the level of FSH of over 40 IU/L and estradiol below 50 pmol/L in women aged below 40 years. Biochemical and other hormonal analysis (free thyroxin, TSH, prolactin, testosterone, karyotype (<30 years of age, ultrasound of the breasts and pelvis are advisable. Optimal therapy is combined estrogen progestagen therapy given in a sequential rhythm, after excluding absolute contraindications. Testosterone can be added to adnexectomized women and those with a low libido. Sequential estrogen progestagen replacement therapy is the first line therapy for ovulation induction in those looking for pregnancy and after that oocyte donation will be advised. Appropriate estro-progestagen therapy improves the quality of life and prevents complications such as cardiovascular diseases, osteoporosis, stroke etc.

  9. Differentiation between ovarian fibroma and subserosal leiomyoma by MR imaging

    Choi, Sang Yeol; Lee, Jun Woo; Kim, Chang Won; Kim, Yong Woo; Lee, Suck Hong [College of Medicine, Pusan National University, Pusan (Korea, Republic of)


    To evaluate the findings and differential points of ovarian fibroma and subserosal leiomyoma, as seen on MR images. The MRimaging findings of 31 surgically confirmed cases of ovarian fibroma (n=3D6) and subserosal leiomyoma (n=3D25; 28) lesions were evaluated. Multiplanar T1-T2-weighted and postcontrast T1-weighted images were obtained using a 1.5T MR unit, and histologic examination was also performed. The MR findings were analyzed in terms of signal intensity, the presence and definition of margin, the histologic finding of hyperintense lesion on T2-weighted images, the presence of the bridging vessel sign, degree of enhancement, and the presence of ipsilateral ovary and ascites. Both fibromas and leiomyomas showed hypo- or isointensity compared with uterine myometrium on T1-weighted images and compared with skeletal muscle on T2-weighted images. The latter revealed intratumoral hyperintense lesions in most cases of ovarian fibroma and subserosal leiomyoma. Three of four ovarian fibromas had a well defined margin after cystic change, but in 24 of 26 subserosal leiomyomas the margin was ill defined. The 'bridging vessel sign' was visible only in subserosal leiomyomas (22/28), and in all cases the enhancement of ovarian fibromas were less than that of myomtetrium. Subserosal leiomyomas (12/28), seen on enhancement as isointense or hyperintense to myometrium, showed a greater degree of enhancement than ovarian fibromas (0/6). Ipsilateral ovary was rarely seen in ovarian fibromas (1/6), but commonly seen in subserosal leiomyomas (20/250. Ascites was present in one case of ovarian fibroma. A defined margin of an intratumoral hyperintense lesion, as seen on T2-weighted images, and the presence or absence of the 'bridging vessel sign' and ipsilateral ovary are useful signs when differentiating between ovarian fibromas and subserosal leiomyomas.

  10. Benign cystic mesothelioma of the appendix presenting in a woman: a case report

    O' Connor, Donal B


    Abstract Introduction Benign cystic mesothelioma or peritoneal inclusion cysts are rare benign abdominal tumors usually occurring in females of reproductive age. These cysts present as abdominopelvic pain or masses but are often found on imaging or incidentally at surgery. They are commonly associated with pelvic inflammatory disease, endometriosis, or ovarian cysts. We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma complicating a presentation of acute appendicitis. Case Presentation A 19-year-old Irish Caucasian woman presented with abdominal pain. Imaging suggested appendicitis with abscess formation. She was treated with antibiotics and scheduled for interval appendicectomy. At laparoscopy, an unusual cystic mass was found arising from the appendix. Histology revealed benign cystic mesothelioma. Conclusion We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma arising from the appendix and complicating a presentation of acute appendicitis. This is a benign pathology, but recurrences are not uncommon. Benign cystic mesothelioma should be included in the differential when investigating pelvic masses or abscesses associated with either appendicitis or pelvic inflammatory disease in women.

  11. Mesothelial neoplasms presenting as, and mimicking, ovarian cancer.

    Mani, Haresh; Merino, Maria J


    Mesotheliomas of the abdominal cavity are rare tumors that primarily involve the peritoneum, mesentery, and omentum. The involvement of the viscera is usually secondary to bulky and extensive serosal disease. We describe 7 cases of mesothelioma in which the initial manifestation was that of an ovarian mass. All patients underwent surgery with a primary diagnosis of ovarian cancer. Clinical histories, gross features, and histology slides were reviewed. Immunostains were performed on all cases and electron microscopy was performed in 2 cases. The patients ranged in age from 22 to 52 years and the lesions ranged in size from 3.8 to 9 cm. Of the 7 cases, 4 were predominantly cystic and 3 were solid. Histologically, all cystic tumors were multicystic mesothelioma, whereas the 3 solid tumors were diffuse malignant mesotheliomas. One patient had a borderline mucinous tumor with the mesothelioma occurring as a mural nodule, an association not described earlier. The oldest patient in this series had a diffuse malignant mesothelioma of the peritoneum with predominant ovarian surface involvement. Mesothelial neoplasms can present as ovarian masses in young women. Awareness of this presentation is important to establish appropriate management.

  12. Profound nephrotic syndrome in a patient with ovarian teratoma

    Abdallah Jeroudi


    Full Text Available The nephrotic syndrome (NS has been associated with a variety of malignancies in a number of reports in the literature, but has been reported in only nine cases associated with ovarian neoplasms. Membranous nephropathy is the most common glomerular pathology causing the NS in patients with solid tumors. There has been only one report of an ovarian neoplasm associated with minimal change disease (MCD. We describe the case of a 36-year-old woman who presented with the NS secondary to biopsy-proven MCD, likely secondary to mature ovarian teratoma. Treatment by tumor removal and prednisone led to remission of the NS. To the best of our knowledge, this is the first report of an ovarian teratoma and the second report of an ovarian neoplasm associated with MCD.

  16. Development of A Mouse Model of Menopausal Ovarian Cancer

    Elizabeth R. Smith


    Full Text Available Despite significant understanding of the genetic mutations involved in ovarian epithelial cancer and advances in genomic approaches for expression and mutation profiling of tumor tissues, several key questions in ovarian cancer biology remain enigmatic: the mechanism for the well-established impact of reproductive factors on ovarian cancer risk remains obscure; questions of the cell of origin of ovarian cancer continue to be debated; and the precursor lesion, sequence, or events in progression remain to be defined. Suitable mouse models should complement the analysis of human tumor tissues and may provide clues to these questions currently perplexing ovarian cancer biology.A potentially useful model is the germ cell-deficient Wv (white spotting variant mutant mouse line, which may be used to study the impact of menopausal physiology on the increased risk of ovarian cancer. The Wv mice harbor a point mutation in c-Kit that reduces the receptor tyrosine kinase activity to about 1-5% (it is not a null mutation. Homozygous Wv mutant females have a reduced ovarian germ cell reservoir at birth and the follicles are rapidly depleted upon reaching reproductive maturity, but other biological phenotypes are minimal and the mice have a normal life span. The loss of ovarian function precipitates changes in hormonal and metabolic activity that model features of menopause in humans. As a consequence of follicle depletion, the Wv ovaries develop ovarian tubular adenomas, a benign epithelial tumor corresponding to surface epithelial invaginations and papillomatosis that mark human ovarian aging. Ongoing work will test the possibility of converting the benign epithelial tubular adenomas into neoplastic tumors by addition of an oncogenic mutation, such as of Tp53, to model the genotype and biology of serous ovarian cancer.Model based on the Wv mice may have the potential to gain biological and etiological insights into ovarian cancer development and prevention.

  17. [Cystic fibrosis in 2008].

    Durieu, I; Josserand, R Nove


    To describe the epidemiological, physiopathological, clinical and therapeutic knowledge concerning cystic fibrosis (CF). Important modifications in the health organization of the care concerning this orphan disease have been implemented in France. The life expectancy has dramatically increased, as well as the knowledge concerning the pathological structure and function of the CFTR gene and protein. This will lead to the development of emerging drug treatments for this lethal disease. The life expectancy is predicted to exceed 40 years for children born in the 2000s. As a result, there has been a tremendous growth of the adult population that reached 40% of the overall approximately 5000 patients included in the CF French registry (Observatoire National de la Mucoviscidose). Lung disease remains the primary cause of morbidity and mortality. The characteristic phenotypic presentation associates bronchial and rhinosinusal symptoms, pancreatic insufficiency and liver disease. Bronchial damage leads to progressive chronic respiratory insufficiency. Diabetes mellitus and osteoporosis frequently appears in adulthood. Neonatal screening has been implemented in France since 2002. It will prevent delayed diagnosis and its deleterious consequences. Some atypical cases of CF presenting only with one or two organ system involvement can be diagnosed in adulthood. Isolated chronic rhinosinusitis, bronchiectasis, congenital bilateral absence of vas deferens, recurrent pancreatitis, allergic bronchopulmonary aspergillosis, and some case of cholangitis may so revealed late form of cystic fibrosis. The health care is organized in cystic fibrosis centres. Despite gene discovery, treatment still remains symptomatic, based on intensive pulmonary and nutritional treatments. Challenges for new treatments are to correct the basic defect, either by gene therapy or by pharmacological modulation of the abnormal physiological processes.

    Ayadi-Kaddour, A; Ismail, O; Hassen, F; Smati, B; Djilani, H; Kilani, T; El Mezni, F


    Mature teratomas of the mediastinum are rare. However, they represent the most common mediastinal germ cell tumours. The aim of this study is to describe their clinical and pathological characteristics. Fourteen cases of mediastinal mature teratoma, diagnosed between January 1992 and December 2006, were reviewed retrospectively, noting the clinical, radiological, surgical, and pathological findings. The patient population consisted of 10 females and 4 males with mean age of 29 years (5-56 years). Chest pain was the main symptom. Imaging features comprised a heterogeneous anterior mediastinal mass containing soft-tissue, fluid, fat, or calcium attenuation, or any combination of the four. Macroscopically all the tumours were cystic, or predominantly cystic, containing mostly grumous material. The mean size was 9 cm (5-12 cm). Histological examination constantly revealed skin with or without appendages. Other components identified were bronchial mucosa (12 cases), fat (12 cases), muscle (10 cases), cartilage (8 cases), bone (7 cases), gastrointestinal mucosa (7 cases), pancreas (5 cases), urothelial epithelium (3 cases), nervous and prostatic tissues (one case each). All the teratomas were mature, and 7 of them were intrathymic. Every form of teratoma occurs in the mediastinum (mature, immature and with malignant transformation) but, in our study, they were exclusively mature. The histology is essentially similar to that of teratomas of gonads. However, pancreatic tissue occurs frequently in mediastinum (54% in literature, 25% in our study) but not in the gonads. On the other hand, thyroid follicles have not yet been seen in mediastinal teratomas.

  19. Ovarian-Sparing Surgery in Pediatric Benign Ovarian Tumors.

    Abbas, Paulette I; Dietrich, Jennifer E; Francis, Jessica A; Brandt, Mary L; Cass, Darrell L; Lopez, Monica E


    To evaluate outcomes of children after ovarian-sparing surgery (OSS) for non-neoplastic and benign neoplastic ovarian lesions. Retrospective cohort study from January 2003 to January 2012. Single, high-volume, tertiary care hospital. Children 18 years of age and younger. None. Postoperative complications and tumor recurrence after OSS. One hundred nine patients underwent OSS with a median age of 13.3 years (interquartile range [IQR], 11.4-15.1 years). Eighty-two patients were treated laparoscopically with 4 conversions to an open procedure. Postoperative complications included surgical site infections in 7 patients (6%). Pathology most commonly revealed functional ovarian cysts (n = 57) and mature teratomas (n = 37). Ninety-four patients (86%) were followed for a median of 10.4 months (IQR, 0.72-30.8 months). Fifty-five patients (60%) had subsequent imaging surveillance a median of 7.6 months postoperatively (IQR, 3.9-13 months). Ten patients (10%) developed a second ipsilateral lesion within a median time of 11 months (IQR, 7.7-24 months), of whom 5 girls had repeated surgery for mass enlargement or persistent abdominal pain at a median time of 10.5 months (IQR, 8.0-12.65 months). Fifty-eight patients (63%) began or resumed menses at their most recent follow-up. Three girls became pregnant after OSS at a median follow-up of 5 years (range, 2.4-6.7 years). Benign ovarian lesions in children can be treated successfully with OSS with low recurrence and repeat surgery rates. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

  20. Cystic fibrosis and sleep.

    Katz, Eliot S


    Sleep disturbances are frequently observed in cystic fibrosis (CF). The resultant sleep fragmentation, short sleep duration, and gas-exchange abnormalities are postulated to contribute to the neurocognitive, cardiovascular, and metabolic abnormalities associated with CF. There are no outcomes data to establish the optimal procedure for screening and treating CF patients for sleep-related respiratory abnormalities. Therapy with supplemental oxygen and bilevel ventilation are widely considered to be effective in the short term, but there are few evidence-based data to support long-term improvements in morbidity and mortality.

  1. [Cystic pyeloureteritis. Our approach].

    Castillo Jimeno, J M; González de Garibay, A S; Ruiz Rubio, J L; Sebastián Borruel, J L


    We report a case of massive cystic pyeloureteritis that had been diagnosed by ureterorenoscopy in a patient with recurrent urinary infection and episodes of nephritic colic. The reports published in the literature indicate there is no specific treatment for this disease whose etiology is unknown. Its pathogenesis has not been well-established and it is difficult to distinguish from other urothelial filling defects. Although it has also been reported that it may progress to malignancy, we believe that the therapeutic approach should be conservative.

  2. Childhood abdominal cystic lymphangioma

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

  4. Fluid-debris level in follicular cysts: a pathognomonic sign of ovarian torsion

    Kiechl-Kohlendorfer, Ursula [Innsbruck Medical University, Clinical Division of Neonatology, Clinical Department of Paediatrics, Innsbruck (Austria); Maurer, Kathrin; Gassner, Ingmar [Innsbruck Medical University, Clinical Division of General Paediatrics, Clinical Department of Paediatrics, Innsbruck (Austria); Unsinn, Karin M. [Innsbruck Medical University, Department of Radiology, Innsbruck (Austria)


    Early diagnosis of ovarian torsion is mandatory to avoid common complications. Sonography is the imaging modality of choice, but diagnosis is still a challenge. To report an additional sonographic feature of ovarian torsion in order to improve diagnostic accuracy. Grey-scale and colour Doppler pelvic sonography was performed in 12 patients with acute onset of intermittent lower abdominal pain and in 1 asymptomatic patient with a palpable mass in the labium majus. Patient ages ranged from 4 months to 17 years. In all patients an enlarged ovary with peripheral cysts was demonstrated. High-resolution sonography detected fluid-debris levels within these cystic structures in 11 of the 13 patients (sensitivity 85%) and provided an additional diagnostic sign. Six patients had cystic teratoma. We confirm the fluid-debris level as a pathognomonic sonographic sign of ovarian torsion with or without associated teratoma. (orig.)

  5. A case of Sertoli-Leydig cell tumour of the ovary with a multilocular cystic appearance on CT and MR imaging

    We present a case of Sertoli-Leydig cell tumour of the ovary in a 14-year-old girl who presented with abdominal distension. Ultrasonography showed a multilocular cystic lesion filled with finely echogenic fluid. Contrast-enhanced CT demonstrated a huge multilocular cystic mass with thickened septa. At MR imaging, the capsule of the cyst was focally thickened, showing intermediate signal intensity on T2-W images. Although extensive cyst formation of Sertoli-Leydig cell tumour is rare, this tumour should be considered in the differential diagnosis of a multilocular cystic ovarian tumour in a young female.

  6. Three-photon imaging of ovarian cancer

    Barton, Jennifer K.; Amirsolaimani, Babak; Rice, Photini; Hatch, Kenneth; Kieu, Khanh


    Optical imaging methods have the potential to detect ovarian cancer at an early, curable stage. Optical imaging has the disadvantage that high resolution techniques require access to the tissue of interest, but miniature endoscopes that traverse the natural orifice of the reproductive tract, or access the ovaries and fallopian tubes through a small incision in the vagina wall, can provide a minimally-invasive solution. We have imaged both rodent and human ovaries and fallopian tubes with a variety of endoscope-compatible modalities. The recent development of fiber-coupled femtosecond lasers will enable endoscopic multiphoton microscopy (MPM). We demonstrated two- and three-photon excited fluorescence (2PEF, 3PEF), and second- and third-harmonic generation microscopy (SHG, THG) in human ovarian and fallopian tube tissue. A study was undertaken to understand the mechanisms of contrast in these images. Six patients (normal, cystadenoma, and ovarian adenocarcinoma) provided ovarian and fallopian tube biopsies. The tissue was imaged with three-dimensional optical coherence tomography, multiphoton microscopy, and frozen for histological sectioning. Tissue sections were stained with hematoxylin and eosin, Masson's trichrome, and Sudan black. Approximately 1 μm resolution images were obtained with an excitation source at 1550 nm. 2PEF signal was absent. SHG signal was mainly from collagen. 3PEF and THG signal came from a variety of sources, including a strong signal from fatty connective tissue and red blood cells. Adenocarcinoma was characterized by loss of SHG signal, whereas cystic abnormalities showed strong SHG. There was limited overlap of two- and three- photon signals, suggesting that three-photon imaging can provide additional information for early diagnosis of ovarian cancer.

  7. Ovarian volume throughout life

    Kelsey, Thomas W; Dodwell, Sarah K; Wilkinson, A Graham


    cancer. To date there is no normative model of ovarian volume throughout life. By searching the published literature for ovarian volume in healthy females, and using our own data from multiple sources (combined n=59,994) we have generated and robustly validated the first model of ovarian volume from...... to about 2.8 mL (95% CI 2.7-2.9 mL) at the menopause and smaller volumes thereafter. Our model allows us to generate normal values and ranges for ovarian volume throughout life. This is the first validated normative model of ovarian volume from conception to old age; it will be of use in the diagnosis...

  9. Estrogen, Progesterone and Epithelial Ovarian Cancer

    Ho Shuk-Mei


    Full Text Available Abstract Ovarian carcinoma (OCa continues to be the leading cause of death due to gynecologic malignancies and the vast majority of OCa is derived from the ovarian surface epithelium (OSE and its cystic derivatives. Epidemiological evidence strongly suggests that steroid hormones, primarily estrogens and progesterone, are implicated in ovarian carcinogenesis. However, it has proved difficult to fully understand their mechanisms of action on the tumorigenic process. New convincing data have indicated that estrogens favor neoplastic transformation of the OSE while progesterone offers protection against OCa development. Specifically, estrogens, particularly those present in ovulatory follicles, are both genotoxic and mitogenic to OSE cells. In contrast, pregnancy-equivalent levels progesterone are highly effective as apoptosis inducers for OSE and OCa cells. In this regard, high-dose progestin may exert an exfoliation effect and rid an aged OSE of pre-malignant cells. A limited number of clinical studies has demonstrated efficacies of antiestrogens, aromatase inhibitors, and progestins alone or in combination with chemotherapeutic drugs in the treatment of OCa. As a result of increased life expectancy in most countries, the number of women taking hormone replacement therapies (HRT continues to grow. Thus, knowledge of the mechanism of action of steroid hormones on the OSE and OCa is of paramount significance to HRT risk assessment and to the development of novel therapies for the prevention and treatment of OCa.

  10. Feline cystic thymoma: a clinicopathologic, immunohistologic, and electron microscopic study of 14 cases.

    Patnaik, A K; Lieberman, P H; Erlandson, R A; Antonescu, C


    Cystic thymoma was diagnosed in 14 cats in a period of 6 years. The most common clinical sign was laboured breathing. The tumours were characterized by various-sized cystic spaces with central vessels. The epithelial cells varied from oval to spindle to polygonal cells enclosing cystic spaces or in pure epithelial cell components. The nuclei of the neoplastic cells had scattered chromatin and small nucleoli. The cytoplasm was pale eosinophilic. The concentration of mature lymphocytes varied from area to area with rare germinal centres. Immunohistochemically, the epithelial cells stained only with AE(1)/AE(3). The central vessels were positive for vimentin, smooth muscle actin, and factor VIII antigen. Electron microscopy revealed that the cyst walls were lined by epithelial cells that were joined by desmosomes, and the walls were well separated from the cystic spaces by a well-defined basement membrane. The neoplastic epithelial cells contained scattered tonofilaments. Three of the cats had metastasis to the lymph nodes and lungs. Two novel cases of ectopic cystic thymoma have also been described. Results of this study reveal that cystic thymoma is uncommon in cats, and that the histomorphologic, immunohistochemical, and electron microscopic features are similar to those of cystic thymoma in humans.

  11. Nutritional Issues in Cystic Fibrosis.

    Solomon, Missale; Bozic, Molly; Mascarenhas, Maria R


    The importance of maintaining adequate nutrition in patients with cystic fibrosis has been well known for the past 3 decades. Achieving normal growth and maintaining optimal nutrition is associated with improved lung function. Comprehensive and consistent nutritional assessments at regular intervals can identify those at risk of nutritional failure and uncover micronutrient deficiencies contributing to malnutrition. Management of malnutrition in cystic fibrosis should follow a stepwise approach to determine the causes and comorbidities and to develop a nutritional plan. Nutritional management is crucial at every stage in a person's life with cystic fibrosis and remains a cornerstone of management.

  12. Intraosseous calcifying cystic odontogenic tumor

    Kler Shikha


    Full Text Available The calcifying odontogenic cyst was first reported by Gorlin et al . in 1962. It had been classified as a neoplasm related to the odontogenic apparatus because of its histological complexity and morphological diversity until it was renamed as a calcifying cystic odontogenic tumor by the WHO, in 2005. Here we describe a case of mandibular calcifying cystic odontogenic tumor in a 75-year-old male, which was present since five years, with a history of occurrence after the extraction of teeth in the involved region. The lesion was surgically removed and a histopathological examination revealed a cystic tumor with predominance of ghost cells and some amount of dentinoid tissue.

  14. Profile of cystic fibrosis

    Mona M. El-Falaki


    Full Text Available It was generally believed that Cystic fibrosis (CF is rare among Arabs; however, the few studies available from Egypt and other Arabic countries suggested the presence of many undiagnosed patients. The aim of the present study was to determine the frequency of CF patients out of the referred cases in a single referral hospital in Egypt. A total of 100 patients clinically suspected of having CF were recruited from the CF clinic of the Allergy and Pulmonology Unit, Children’s Hospital, Cairo University, Egypt, throughout a 2 year period. Sweat chloride testing was done for all patients using the Wescor macroduct system for collection of sweat. Quantitative analysis for chloride was then done by the thiocyanate colorimetric method. Patients positive for sweat chloride (⩾60 mmol/L were tested for the ΔF508 mutation using primer specific PCR for cystic fibrosis transmembrane conductance regulator (CFTR gene. Thirty-six patients (36% had a positive sweat chloride test. The main clinical presentations in patients were chronic cough in 32 (88.9%, failure to thrive in 27 (75%, steatorrhea in 24 (66.7%, and hepatobiliary involvement in 5 (13.9%. Positive consanguinity was reported in 50% of CF patients. Thirty-two patients were screened for ΔF508 mutation. Positive ΔF508 mutation was detected in 22 (68.8% patients, 8 (25% were homozygous, 14 (43.8% were heterozygous, and 10 (31.3% tested were negative. CF was diagnosed in more than third of patients suspected of having the disease on clinical grounds. This high frequency of CF among referred patients indicates that a high index of suspicion and an increasing availability of diagnostic tests lead to the identification of a higher number of affected individuals.

    Gursli, S; Haanaes, O C


    This article is intended as a brief practical guide for physicians and physiotherapists concerned with the treatment of cystic fibrosis. Physiotherapeutic techniques for the treatment of chest diseases have been developed and modified as advances have taken place in the medical management of cystic fibrosis. The article describes forced expiratory technique, positive expiratory pressure, postural drainage, autogenic drainage and other techniques. Patients with cystic fibrosis live longer and have a better quality of life than ever before, but progressive deterioration of lung function will always be their most serious problem. Physical activity and chest physiotherapy are essential parts of all treatment regimens for cystic fibrosis. It is important to realize that the physiotherapist is a very important member of the team which includes nurses, physicians-and the patient.

    To obtain the characteristic sonographic findings of ovarian hemorrhage and investigate the usefulness of ultrasonography in the diagnosis. Forty-nine cases presenting acute abdomen diagnosed as ovarian hemorrhage by ultrasonography or surgicopathological confirmation. We observed the size and margin of the ovary, size, pattern, shape, wall and internal echogenecity of the masses and the amount of hemoperitoneum. We also performed a color Doppler study to evaluate the blood flow pattern and resistive index (RI). The age of patients were between 21-41. Most symptoms occurred from days 14 to 30 of her menstrual cycle and were presented for less than 24 hours. Twenty patients had a history of intercourse shortly before the onset of the symptom. Thirty two cases involved the right ovary while the other 17 cases involved the left. All patients had a negative urine or serum hCG test except for 4 pregnant women. The size of the ovary was measured as mean 5.1 cm and marginal irregularly was noted in 36 cases. Mixed echoic solid masses were observed in 6 cases and variable echogenecity of cystic masses were seen in 43 cases. Maximal diameter of adnexal masses were measured as mean 3.95 cm. Internal echogenecity of cystic masses appeared as mainly heterogeneous (21). Twenty two cystic masses had a thick irregular wall and 17 had a thin smooth wall. Hypoechoic rim like halo surrounding was noted in 17 cystic masses. 17 cases seemed to have a small amount of hemoperitoneum, a moderate amount in 22 cases and a large amount in 9 cases. The blood flow pattern of cystic masses showed a rim (29) and spotty (8) pattern in the color Doppler study. Measured RI was 0.41 (mean). Fertile women with the complaint of acute abdominal pain, who has the laboratory data of negative hCG test, ultrasonographic findings of enlargement of ovary with irregular margin, heterogeneous echoic cystic mass, peripheral halo surrounding the mass, hemoperitoneum and low resistance index of peripheral blood

  4. High-resolution proton nuclear magnetic resonance spectroscopy of ovarian cyst fluid.

    Boss, E A; Moolenaar, S H; Massuger, L F; Boonstra, H; Engelke, U F; de Jong, J G; Wevers, R A


    Most ovarian tumors are cystic structures containing variable amounts of fluid. Several studies of ovarian cyst fluid focus on one specific metabolite using conventional assay systems. We examined the potential of (1)H-nuclear magnetic resonance spectroscopy in evaluation of the overall metabolic composition of cyst fluid from different ovarian tumors. Ovarian cyst fluid samples obtained from 40 patients with a primary ovarian tumor (12 malignant and 28 benign) were examined. After deproteinization and pD standardization, we performed (1)H-NMR spectroscopy on a 600 MHz instrument. With (1)H-NMR spectroscopy we found detectable concentrations of 36 metabolites with high intersample variation. A number of unassigned resonances as well as unexpected metabolites were found. We introduce an overall inventory of the low-molecular-weight metabolites in ovarian cyst fluid with corresponding resonances. Significant differences in concentration (p overview of low-molecular-weight proton-containing metabolities present in ovarian cyst fluid samples. The metabolic composition of cyst fluid differs significantly between benign and malignant ovarian tumors. Furthermore, differences between benign subgroups possibly related to histopathological behaviour can be detected. The presence of N-acetyl aspartic acid and 5-oxoproline exclusively in serous cystadenoma samples is remarkable. Future studies will concentrate on these findings and explore the possibilities of extrapolating information from the in vitro studies to in vivo practice, in which metabolic differences between malignant and benign subtypes can be of great importance in a pre-operative phase.

  5. [Right ovarian vein syndrome].

    Arvis, G


    Right ovarian vein syndrome is revealed in pregnancy by right lumbar pains, and even by nephritic colics. It results from a congenital malposition of the right ovarian vein, which presses the right ureter on the external iliac artery. Diagnosis is by intravenous urography and retrograde ureteral pyelography. If pain persists despite treatment by analgesics, it may be necessary to place a double-J catheter, and to operate after delivery to ligate the ovarian vein.

  6. Pathobiology of ovarian carcinomas

    Mojgan Devouassoux-Shisheboran; Catherine Genestie


    Ovarian tumors comprise a heterogeneous group of lesions, displaying distinct tumor pathology and oncogenic potentiel. These tumors are subdivided into three main categories: epithelial, germ cell, and sex-cord stromal tumors. We report herein the newly described molecular abnormalities in epithelial ovarian cancers (carcinomas). Immunohistochemistry and molecular testing help pathologists to decipher the significant heterogeneity of this disease. Our better understanding of the molecular basis of ovarian carcinomas represents the first step in the development of targeted therapies in the near future.

    Aim: To assess the characteristics of [{sup 18}F]-fluoro-2-deoxy-D-glucose (FDG) uptake in cases of ovarian metastasis using positron-emission tomography/computed tomography (PET/CT). Materials and methods: Twelve patients with 16 ovarian metastases arising from colon cancer (n = 6), breast cancer (n = 4), gastric cancer (n = 3), and pancreatic cancer (n = 3) who underwent FDG-PET/CT examination were included in this study. The effect of lesion size and morphological pattern (predominantly solid or cystic) on FDG uptake was evaluated using the quantitative standardized uptake value (SUV). Results: The mean maximum SUV for the 16 lesions was 4.6 {+-} 2.4 (range 1.8 {approx} 9.9). The Pearson correlation coefficient test showed no significant correlation between maximum SUV and lesion size (r = 0.21, p = 0.42). The maximum SUV of solid (n = 5) and cystic (n = 11) lesions was 5.5 {+-} 2.7 and 4.3 {+-} 2.2, respectively, and the difference was not significant (p = 0.43). Breast cancer showed the highest maximum SUV (6.4 {+-} 3.6), followed by colon cancer (5.3 {+-} 1.4), gastric cancer (3.3 {+-} 0.5), and pancreatic cancer (2.2 {+-} 0.6). Conclusion: Ovarian metastases show a variable maximum SUV with mild to intense FDG uptake.

  8. Gestações espontâneas após punção ovariana para maturação in vitro em mulheres com síndrome dos ovários policísticos Spontaneous pregnancies after ovarian puncture for in vitro maturation in women with the polycystic ovary syndrome

    Full Text Available OBJETIVO: relatar três casos de gestações espontâneas em portadoras da síndrome dos ovários policísticos (SOP que ocorreram nos meses subsequentes à realização de punção ovariana transvaginal para captação oocitária para a maturação in vitro. MÉTODOS: foram incluídas no estudo três pacientes inférteis portadoras de SOP submetidas à maturação in vitro dos oócitos sem estimulação ovariana prévia. Durante o procedimento da coleta dos oócitos, cada ovário foi perfurado de quatro a oito vezes. RESULTADO: nenhuma paciente engravidou com a técnica da maturação in vitro. Avaliando o seguimento dos casos, em sete meses após o procedimento, as três pacientes engravidaram sem o auxílio de técnicas de reprodução assistida, resultando em três nascimentos. CONCLUSÕES: as múltiplas perfurações nos ovários destas pacientes portadoras da SOP, durante o procedimento de coleta dos oócitos, podem ter contribuído para a obtenção da gestação nos meses subsequentes ao procedimento.PURPOSE: to report three cases of spontaneous gestation in women with polycystic ovarian syndrome (PCOS, that occurred in the months subsequent to transvaginal oocyte retrieval for in vitro maturation (IVM. METHODS: three infertile patients with PCOS, submitted to oocytes' IVM without previous ovarian stimulation, were included in the study. During the procedure of oocytes' collection, each ovary was drilled from four to eight times. RESULTS: none of the patients got pregnant with the IVM technique. Evaluating the cases' follow-up, in seven months after the procedure, the three patients got pregnant without the help of techniques of assisted reproduction, which resulted in three births. CONCLUSIONS: the multiple drillings in the ovary of these patients with PCOS, during the process to collect oocytes, may have contributed to their pregnancy in the months following the procedure.

    Xiaoping Yu


    Objective: To study the CT features of ovarian dysgerminoma. Methods: CT findings of 11 cases with pathologi-cally-proved dysgerminoma of ovary were retrospectively analyzed. Results: All the 11 cases were solitary. The maximum diameter of lesion was averagely 17.1 cm. The tumor presented as a solid (n = 8) or cystic-solid (n = 3) mass. After contrast medium administration, the solid component of the lesions showed prominent enhancement on CT scan. Blood vessels were found in 5 masses. Of the 11 cases with ovarian dysgerminoma, invasion of adjacent structure (n = 4), ascites (n = 6) and adenopathy in pelvic wall (n = 3) were demonstrated. Conclusion: Ovarian dysgerminoma has its CT characteristics. Associ-ated with clinic data, CT is helpful in the diagnosis and differential diagnosis of ovarian dysgerminoma.

    Song, Soon Young; Choi, Yo Won; Jeon, Eui Yong; Jeon, Seok Chol; Seo, Heung Suk; Hahm, Chang Kok [School of Medicine, Hanyang University, Seoul (Korea, Republic of)


    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

  11. Activated Wnt Signaling in Stroma Contributes to Development of Pancreatic Mucinous Cystic Neoplasms

    Sano, Makoto; Driscoll, David R.; De Jesus-Monge, Wilfredo E.; Klimstra, David S.; Lewis, Brian C.


    BACKGROUND & AIMS Pancreatic mucinous cystic neoplasm (MCN), a cystic tumor of the pancreas that develops most frequently in women, is a potential precursor to pancreatic ductal adenocarcinoma. MCNs develop primarily in the body and tail of the pancreas and are characterized by the presence of a mucinous epithelium and ovarian-like subepithelial stroma. We investigated the involvement of Wnt signaling in KRAS-mediated pancreatic tumorigenesis and development of MCN in mice, and Wnt activation in human MCN samples. METHODS LSL-KrasG12D, Ptf1a-cre mice were crossed with elastase-tva mice to allow for introduction of genes encoded by the replication-competent avian sarcoma-leukosis virus long-terminal repeat with splice acceptor viruses to pancreatic acinar cells and acinar cell progenitors, postnatally and sporadically. Repeat with splice acceptor viruses that expressed Wnt1 were delivered to the pancreatic epithelium of these mice; pancreatic lesions were analyzed by histopathology and immunohistochemical analyses. We analyzed levels of factors in Wnt signaling pathways in 19 MCN samples from patients. RESULTS Expression of Wnt1 in the pancreatic acinar cells and acinar cell progenitors of female mice led to development of unilocular or multilocular epithelial cysts in the pancreas body and tail, similar to MCN. The cystic lesions resembled the estrogen receptor– and progesterone receptor–positive ovarian-like stroma of MCN, but lacked the typical mucinous epithelium. Activated Wnt signaling, based on nuclear localization of β-catenin, was detected in the stroma but not cyst epithelium. Wnt signaling to β-catenin was found to be activated in MCN samples from patients, within the ovarian-like stroma, consistent with the findings in mice. CONCLUSIONS Based on studies of mice and pancreatic MCN samples from patients, the canonical Wnt signaling pathway becomes activated and promotes development of the ovarian-like stroma to contribute to formation of MCNs.

    Pulmonary cystic echinococosis, a zoonosis caused by the larvae of the dog tapeworm Echinococcus granulosus, is considered as a major public health problem in those countries where dogs are used to care for large herds because of the incapacitating effects produced in affected population. The ratio lung:liver involvement is higher in children than in adults. A higher proportion of lung cases are discovered incidentally on a routine x-ray evaluation; the majority of infected people remain asymptomatic until the cyst enlarges sufficiently to cause symptoms. The majority of symptoms are caused by mass effect from the cyst volume; the presence of complications caused by cysts broke changes the clinical presentation; the principal complication is cyst rupture, producing cough, chest pain, hemoptysis, or vomica. Diagnosis is obtained by imaging evaluation (Chest X-ray or CT scan), supported by serology in the majority of cases. Surgery is the main therapeutic approach, having as principal objective, the removal of the parasite, preventing intraoperative dissemination; the use of pre surgical chemotherapy reduces the chances of seeding and recurrence; treatment using benzimidazoles is the preferred treatment when surgery is not available, or complete removal is not feasible PMID:20216420

  14. Chlamydia Peritonitis and Ascites Mimicking Ovarian Cancer

    Anar Gojayev


    Full Text Available Background. Pelvic inflammatory disease (PID rarely results in diffuse ascites. Severe adhesive disease secondary to PID may lead to the formation of inclusion cysts and even pelvic peritoneal nodularity due to postinflammatory scarring and cause an elevation of serum CA-125 levels. The constellation of these findings may mimic an ovarian neoplasm. Case. We report a case of a 22-year-old female who presented with multiple pelvic cysts and diffuse ascites due to Chlamydia trachomatis infection. The initial gynecologic exam did not reveal obvious evidence of PID; however, a positive Chlamydia trachomatis test, pathologic findings, and the exclusion of other etiologies facilitated the diagnosis. Conclusion. Chlamydia trachomatis and other infectious agents should be considered in the differential diagnosis of a young sexually active female with abdominal pain, ascites, and pelvic cystic masses. Thorough workup in such a population may reduce the number of more invasive procedures as well as unnecessary repeat surgical procedures.

  16. Ovarian steroid cell tumor in women with polycystic ovarian syndrome: a case report

    Yarandi F


    Full Text Available Background: Steroid cell tumor is one of the rare ovarian tumors and forms 0.1% of all ovarian tumors, divided to three subgroups. Steroid cell tumor that are not otherwise specified (NOS are the most common type and represent 60% of steroid cell tumors. One of the most known signs of this tumor is hormonal function, especially androgenic effects of it. Primary treatment consists of eradication of tumor via surgery.Case presentation: The patient is a 29 years old female with history of poly cystic ovarian syndrome since 10 years ago, who attended to the clinic of General Women Hospital of Tehran in January 2011. In pelvic ultrasonography, there was a 6449mm mass in the right adnexa consisting of homogeneous component. She underwent laparotomy and unilateral salpingoophorectomy was done. Pathological report was steroid cell tumor of ovary.Conclusion: The aim of this study is reporting one of the rare tumors of ovary and assessment of the correct way of diagnosis and treatment of it.

  17. Cystic Lesions in Autoimmune Pancreatitis

    Macarena Gompertz


    Full Text Available Autoimmune pancreatitis (AIP can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered after corticosteroid therapy. One year later, he presented with a recurrent episode of AIP with elevated IgG4 levels, accompanied by the appearance of multiple intrapancreatic cystic lesions. All but 1 of these cysts disappeared after steroid treatment, but the remaining cyst in the pancreatic head was even somewhat larger 1 year later. Pancreatoduodenectomy was finally performed. Histology showed the wall of the cystic lesion to be fibrotic; the surrounding pancreatic tissue presented fibrosis, atrophy and lymphoplasmacytic infiltration by IgG4-positive cells, without malignant elements. Our case illustrates the rare possibility that cystic lesions can be part of AIP. These pseudocysts appear in the pancreatic segments involved in the autoimmune disease and can be a consequence of the local inflammation or related to ductal strictures. Steroid treatment should be initiated, after which these cysts can completely disappear with recovery from AIP. Surgical intervention may be necessary in some exceptional cases.

  18. Using Cystic Fibrosis Therapies for Non-Cystic Fibrosis Bronchiectasis.

    ElMaraachli, Wael; Conrad, Douglas J; Wang, Angela C C


    Non-cystic fibrosis bronchiectasis (NCFB) is an increasingly prevalent disease that places a significant burden on patients and health systems globally. Although many of the therapies used to treat NCFB were originally developed as cystic fibrosis (CF) therapies, not all of them have been demonstrated to be efficacious in NCFB and some may even be harmful. This article explores the evidence for which therapeutic strategies used to treat CF have been translated into the care of NCFB. The conclusion is that therapies for adult NCFB cannot be simply extrapolated from CF clinical trials, and in some instances, doing so may actually result in harm.

  19. A Case of Bilateral Cystic Partially Differentiated Nephroblastoma vs Cystic Wilms' Tumor: Highlighting a Diagnostic Dilemma.

    Stout, Thomas E; Au, Jason K; Hicks, J M; Gargollo, Patricio C


    Cystic partially differentiated nephroblastoma (CPDN) is a rare multicystic renal tumor along the spectrum of cystic nephroma and cystic Wilms' tumor. There have only been two previously reported cases of bilateral CPDN in the literature. We present here a case of bilateral CPDN vs cystic Wilms' tumor treated with neoadjuvant and adjuvant chemotherapy in addition to a bilateral partial nephrectomy. We also review the relevant literature regarding CPDN in an effort to aid in diagnosis and management of these rare cystic renal tumors.

  9. Benign and Suspicious Ovarian Masses—MR Imaging Criteria for Characterization: Pictorial Review

    A. L. Valentini


    Full Text Available Ovarian masses present a special diagnostic challenge when imaging findings cannot be categorized into benign or malignant pathology. Ultrasonography (US, Computed Tomography (CT, and Magnetic Resonance Imaging (MRI are currently used to evaluate ovarian tumors. US is the first-line imaging investigation for suspected adnexal masses. Color Doppler US helps the diagnosis identifying vascularized components within the mass. CT is commonly performed in preoperative evaluation of a suspected ovarian malignancy, but it exposes patients to radiation. When US findings are nondiagnostic or equivocal, MRI can be a valuable problem solving tool, useful to give also surgical planning information. MRI is well known to provide accurate information about hemorrhage, fat, and collagen. It is able to identify different types of tissue contained in pelvic masses, distinguishing benign from malignant ovarian tumors. The knowledge of clinical syndromes and MRI features of these conditions is crucial in establishing an accurate diagnosis and determining appropriate treatment. The purpose of this paper is to illustrate MRI findings in neoplastic and non-neoplastic ovarian masses, which were assessed into three groups: cystic, solid, and solid/cystic lesions. MRI criteria for the correct diagnosis and characteristics for differentiating benign from malignant conditions are shown in this paper.

  10. Evaluation of magnetization transfer ratio in ascites and pelvic cystic masses

    Okada, Susumu [Nippon Medical School, Inba, Chiba (Japan). Chiba-Hokuso Hospital; Kato, Tomoyasu; Yamashita, Takashi [and others


    To investigate the feasibility of magnetization transfer contrast (MTC) in characterization of pelvic cystic masses and ascites, in vitro studies were performed. Cystic fluids were taken from operative specimens of ten ovarian cystic masses (five mucinous cystadenomas, one cystadenocarcinoma, two serous cystadenocarcinomas, two clear cell carcinomas) and three non-ovarian pelvic cysts (one paraovarian cyst, one pseudomyxoma peritonei, one pelvic abscess). Samples of ascitic flied were drawn by peritoneal puncture in twenty patients (thirteen with peritonitis carcinomatosa, five with liver dysfunction, two with renal dysfunction). Total protein content in ascitic fluids was measured. Magnetization transfer ratio (MTR) was calculated by the signal intensities under the gradient echo sequence with and without the application of off-resonance pulses. The relative signal intensities (RSI) relative to water in T{sub 1} and T{sub 2} weighted images were obtained using spin echo sequence. There was no correlation between histological type of pelvic mass and MTR and RSI. Good correlation (R{sup 2}=0.761) was obtained between MTR and protein content in ascitic fluids, whereas no correlation was noted between RSI and protein content in ascitic fluids. These results suggest that MTC is not useful in the characterization of pelvic masses but is applicable in the differentiation between exudative ascites and transudative ascites. (author)

  11. Biochemical analysis of cystic fluid in the diagnosis of fetal intra-abdominal masses.

    Lecarpentier, Edouard; Dreux, Sophie; Blanc, Thomas; Schaub, Bruno; Ville, Yves; Mandelbrot, Laurent; El Ghoneimi, Alaa; Oury, Jean-François; Muller, Françoise


    The aim of the study was to evaluate a biochemical analysis of fluid sampled in utero from fetal abdominal cystic masses. A retrospective study of 42 intra-abdominal cystic masses [ovarian cysts (n = 22), cloaca (n = 8), urodigestive fistulae (n = 4), and urogenital sinuses (n = 8)] was carried out. The control group (n = 30) consisted of fetal urine. Seven biochemical markers were assayed: sodium, estradiol, β(2) -microglobulin, total proteins and digestive enzymes, gamma-glutamyl transpeptidase, aminopeptidase M, and intestinal alkaline phosphatase isoenzyme. Outcome of pregnancies and final diagnosis of intra-abdominal mass were known in all cases. Biochemical patterns allowed to demonstrate (1) an ovarian origin based on elevated level of estradiol and of total proteins (100% specificity, 100% sensitivity); (2) urodigestive fistula based on the presence of high levels of digestive enzymes (cloaca in female fetuses or recto-urethral fistula in male fetuses); and (3) a renal origin (urinary pattern with low total proteins and absence of digestive enzymes); however, a biochemical pattern could not differentiate between fetal urogenital sinus and megacystis. Etiological diagnosis of a fetal cystic abdominal mass could impact both prenatal and postnatal management providing adapted prenatal counseling by a pediatric surgeon in surgically correctable congenital anomalies. © 2012 John Wiley & Sons, Ltd.

  12. Mucinous cystic neoplasm of the liver with low grade dysplasia of the liver.

    Pirdopska, T; Terziev, I; Taneva, I; Dimitrova, V


    Mucinous cystic neoplasm (MCN) with low grade dysplasia of the liver is rare. It had been previously called hepatobiliary cystadenoma and is seen almost exclusively in women without an associated invasive carcinoma. There are different theories for development of MCN of the liver. One of these is developing from endodermal immature stroma or primary yolk cells implanted during embryogenesis. Another theory refers to the prevalence of hepatic mucinous cystic neoplasm in segment IV, which may support an implant origin because hamartomatous lesions commonly develop in segment IV. The third theory concerns the expression of oestrogen receptor or progesterone receptor in ovarian-like stroma, which also supports a putative role for female hormones in the tumorogenesis. MCN of the liver is a cystic-forming epithelial neoplasm, usually showing no communication with the bile ducts, composed of cuboidal to columnar, variably mucin-producing epithelium, associated with ovarian-type subepithelial stroma. We present a case of MCN with low grade dysplasia of the liver in a young woman whose working surgical diagnosis was Echinococcus cyst. The MCN diagnosis was confirmed with Immunohistochemical study.

  13. Tubo-ovarian abscess with Morganella morganii bacteremia.

    Chou, Yen Yi; Chiu, Sheng Kang; Lai, Hung Cheng; Chang, Feng Yee


    Tubo-ovarian abscess caused by Morganella morganii is unusual. A 54-year-old menopausal woman visited the emergency room with lower abdominal pain, vomiting, and fever for 4 days. Pelvic examination revealed lifting tenderness over the right adnexum without motion tenderness of the uterus. Pelvic sonogram revealed a cystic lesion with heterogeneous content in the right ovary. Salpingo-oophoritis was suspected. Clindamycin and gentamicin were administered intravenously after obtaining blood cultures. Laparoscopy was done because of sustained fever, and an ovarian abscess was found. Laparoscopic salpingo-oophorectomy was performed. The patient was discharged 5 days later and oral clindamycin was prescribed. However, she was readmitted due to intermittent fever. The result of blood culture obtained before surgery disclosed M. morganii, which was resistant to clindamycin and cefazolin. Her symptoms resolved after administration of intravenous flomoxef. This report highlights the fact that antimicrobial resistance of M. morganii may complicate the management and outcome of this infection.

  15. Selecting treatment method for ovarian masses in children - 24 years of experience.

    Łuczak, Justyna; Bagłaj, Maciej


    Epidemiology and pathology of ovarian tumors in the pediatric population are very different of these encountered in women. Few attempts have been made to analyze the whole spectrum of ovarian pathology in children, and only some of them included series of more than 200 cases. We performed a retrospective analysis of clinical and diagnostic aspects of ovarian tumors and tumor-like lesions in girls in order to identify the characteristics associated with malignancy with an attempt to elaborate a clinical management algorithm. The study group comprised 214 patients operated on for ovarian tumor in years 1991-2014 at the pediatric surgical center. Non-neoplastic ovarian lesion was diagnosed in 127 females. Sixty-five patients had a benign tumor and 22 had a malignant lesion. Abdominal pain was the most common symptom in the non-malignant lesion group. Patients with ovarian malignancy presented predominantly with abdominal distension and palpable mass. In the non-malignant group imaging studies revealed cystic lesion in 124 patients (68.89%) and solid mass in 10 (5.55%). Malignant lesion showed a solid or mixed structure in all cases. Positive tumor markers were noted in 14 (13.7%) patients with a benign lesion and in 14 (70%) with ovarian malignancy. Large lesions were found in 77.3% of girls with a malignant mass, while only in 32.8% of patients with a benign lesion (p pediatric surgical centers.

  16. Bilateral Tubo Ovarian Abscess Mimics Ovarian Cancer on MRI and {sup 18F} FDG PET/CT

    Rakheja, Rajan; Hickeson, Marc [Royal Victoria Hospital, McGill Univ. Health Centre, Montreal (Canada); Makis, William [Brandon Regional Health Centre, Brandon (Canada)


    A 20 year old woman, who presented with a several week history of abdominal pain, was referred for magnetic resonance imaging (MRI) and {sup 18F} fluorodeoxy glucose (FDG) positron emission tomography (PET)/computed tomography (CT) after an ultrasound showed complex cystic masses arising from both ovaries. The MRI and {sup 18F} FDG PET/CT imaging characteristics of the ovarian masses were strongly suspicious for malignancy, and the masses were surgically removed. Histopathological evaluation revealed a bilateral tuboovarian abscess, with no evidence of malignancy. This case highlights a potentially serious pitfall in the evaluation of suspicious pelvic masses by {sup 18F} FDG PET/CT, Whereby a complex bilateral tuboovarian abscess may mimic the PET/CT imaging characteristics of an ovarian or pelvic malignancy.

  17. Pancreatic Metastasis of High-Grade Papillary Serous Ovarian Carcinoma Mimicking Primary Pancreas Cancer: A Case Report

    Yusuf Gunay


    Full Text Available Introduction. Reports of epithelial ovarian carcinomas metastatic to the pancreas are very rare. We herein present a metastasis of high grade papillary serous ovarian cancer to mid portion of pancreas. Case. A 42-year-old patient was admitted with a non-specified malignant cystic lesion in midportion of pancreas. She had a history of surgical treatment for papillary serous ovarian adenocarcinoma. A cystic lesion was revealed by an abdominal computerized tomography (CT performed in her follow up . It was considered as primary mid portion of pancreatic cancer and a distal pancreatectomy was performed. The final pathology showed high-grade papillary serous adenocarcinoma morphologically similar to the previously diagnosed ovarian cancer. Discussion. Metastatic pancreatic cancers should be considered in patients who present with a solitary pancreatic mass and had a previous non-pancreatic malignancy. Differential diagnosis of primary pancreatic neoplasm from metastatic malignancy may be very difficult. A biopsy for tissue confirmation is required to differentiate primary and secondary pancreatic tumors. Although, the value of surgical resection is poorly documented, resection may be considered in selected patients. Conclusion. Pancreatic metastasis of ovarian papillary serous adenocarcinoma has to be kept in mind when a patient with pancreatic mass has a history of ovarian malignancy.

  18. Multiple ovarian cysts in a young girl with severe hypothyroidism.

    Panico, Annalisa; Lupoli, Gelsy Arianna; Fonderico, Francesco; Colarusso, Sara; Marciello, Francesca; Poggiano, Maria Rita; Del Prete, Michela; Magliulo, Raffaele; Iervolino, Paolo; Lupoli, Giovanni


    Case study of a young female patient with severe hypothyroidism due to autoimmune thyroiditis and multiple ovarian cysts is reported. A 14-year 7-month-old girl presented with pelvic and abdominal pain and severe asthenia. Her last menstrual period was 10 months before presentation. Physical examination showed obesity; apathetic and flat expression; periorbital puffiness; pale, cold, dry skin and slow sustained reflexes; swelling in the hands and feet; no galactorrhea; a hardly palpable thyroid gland; and ovaries with a palpable irregular surface. Her heart rate was 90 bpm with a blood pressure within the normal range (110/70 mmHg). Laboratory findings showed severe hypothyroidism (thyroid-stimulating hormone [TSH]: 960 mIU/L), gravis macrocytic anemia, hyperfibrinogenemia, and hyperprolactinemia. Imaging examinations revealed a normal-size thyroid with irregular echogenicity, strongly hypoechogenous area at the neck ultrasonography, bilateral multilocular ovarian masses with cystic components at pelvic ultrasound and computed tomography, and both anterior and posterior pericardial effusion at echocardiography. As soon as thyroid replacement therapy was initiated, all symptoms progressively disappeared and biochemical and hormonal values normalized, while the right ovary did not decrease in size during the follow-up period. For this reason, our patient underwent right ovarian wedge resection 14 months after the initiation of medication replacement. Ovarian histological examination showed a benign ovarian cyst with extensive hemorrhage and myxedematous infiltration. It is concluded that it is important to recognize early in young girls the association between large multiple ovarian cysts and high elevated levels of TSH in order to resolve this disorder with substitutive therapy.

  19. Computed Tomography Appearance of Ovarian Fibrothecomas With and Without Torsion

    Chee-Wai Mak; Wen-Sheng Tzeng; Chin-Yu Chen (Dept. of Diagnostic Imaging, Chi-Mei Medical Center, Yung Kang, Tainan, Taiwan (China))


    Background: Fibrothecomas are the most common solid ovarian tumors and may undergo torsion. Early diagnosis of these tumors is important in order to allow prompt surgical treatment. Purpose: To describe the features of ovarian fibrothecoma on computed tomography (CT) and to determine the possibility of detecting tumor torsion in this kind of tumor. Material and Methods: The CT images of 11 patients with ovarian fibrothecomas in the past 8 years at our hospital were retrospectively reviewed. The CT attenuation values of each tumor were measured in both non-enhanced and enhanced scans. The size and degree of enhancement were evaluated and correlated with tumor torsion. All cases were pathologically proven. Results: Three kinds of tumor pattern were found: 1) homogeneous tumor with significant enhancement containing scattered, low-attenuated regions after contrast injection; 2) heterogeneous tumor with mild enhancement after contrast injection; and 3) low-attenuated soft-tissue mass with no obvious enhancement after contrast injection. Conclusion: Fibrothecomas usually appear as a homogeneous solid tumor with varying degrees of enhancement. Calcification may be present and, as these tumors enlarge, myxoid or cystic degeneration may occur, resulting in a heterogeneous pattern. The larger the tumor, the greater is the chance of torsion. Lack of tumor enhancement is the most reliable sign for detection of ovarian torsion and should facilitate prompt surgical intervention to remove damaged tissue

    Full Text Available Ovarian mucinous cystadenoma is a benign tumour that arises from the surface epithelium of the ovary. It tends to be huge in size if not detected early. We describe a 32 year old woman (para 1+0 presented with marked abdominal distension, discomfort and vague pain in the abdomen with dyspepsia, anorexia, nausea, vomiting and irregular menstruation for last three months with the suspicion of pregnancy. On examination no findings were in favour of pregnancy, rather an ill defined abdominal mass about 30 weeks pregnancy size was found. Transabdominal USG revealed a big multiloculated ovarian cyst of about 25x20 cm. On laparotomy a huge cystic mass was noticed arising from left ovary. The cyst wall was smooth, intact and without any external projection though adherent with the left fallopian tube and left salpingo-oophorectomy was done. Histopathological examination revealed an ovarian cyst compatible with mucinous cystadenoma. Such giant ovarian tumours have become rare in current practice. This case report emphasizes the significance of thorough evaluation of all women presented with non specific complaints like vague abdominal pain or simple dyspepsia. Although the condition is rare, it is potentially dangerous in the massive form if not timely diagnosed and managed properly. With the increasing awareness of such conditions, more and more cases could be detected and reported early.

  5. Pseudomembranous colitis in cystic fibrosis.

    Nagakumar, Prasad


    Cystic fibrosis (CF) patients may require frequent courses of antibiotics and repeated hospital admissions. Although children with CF have high carriage rate for C.difficile, they rarely develop colitis. Pseudomembranous colitis is more common in adult post lung transplant CF patients. Although rare, paseudomembranous colitis should be considered in CF patients presenting with abdominal symptoms even in the absence of diarrhoea.

  10. Anaplastic carcinoma associated with a mucinous cystic neoplasm of the pancreas during pregnancy: Report of a case and a review of the literature

    Kenichi Hakamada; Takuya Miura; Akitoshi Kimura; Masaki Nara; Yoshikazu Toyoki; Shunij Narumi; Mutsuo Sasak


    Oncogenesis of anaplastic carcinoma of the pancreas is a subject of controversy, because it shows sarcomatous nature with extremely poor prognosis. We herein report an unusual case of anaplastic carcinoma occurring with a recurrent mucinous cystic neoplasm in a 38-year-old female. A 10-cm retroperitoneal cystic mass was pointed out in the first pregnancy and a probable diagnosis of mucinous cystic neoplasm was made in October 2000. She refused surgery first and delivered her baby uneventfully. During her second pregnancy in 2002, however, she presented hematemesis and underwent urgent distal pancreatectomy, splenectomy and partial resection of the gastric wall where the tumor perforated. A diagnosis of borderline-type mucinous cystic neoplasm with ovarian-like stroma was made. Nine months later, CT visualized a recurrent cystic tumor near the pancreatic stump, which was subsequently resected. Pathology revealed that the tumor was composed of two different components of borderline-type mucinous cystic neoplasm and anaplastic carcinoma. The latter was intensely positive for vimentin, CD68, p53 and focally for cytokeratin, suggesting both sarcomatous and carcinomatous differentiation. She survived four years after the second surgery without tumor recurrence. Although the origin of anaplastic carcinoma has not been determined yet, it should be remembered that anaplastic carcinoma can occur in association with mucinous cystic neoplasm of more benign histology.

  11. [Therapeutic update in cystic fibrosis].

    Durupt, S; Nove Josserand, R; Durieu, I


    We present the recent therapeutic advances in the cystic fibrosis care. It concerns improvements in symptomatic treatment with the development of dry powder inhaled antibiotics that improved quality of life, and innovative treatments namely the modulators of the cystic fibrosis transmembrane protein conductance regulator (CFTR), molecules which act specifically at the level of the defective mechanisms implied in the disease. The life expectancy of cystic fibrosis patients born after 2000, is estimated now to be about 50 years. This improvement of survival was obtained with the organization of the care within the specialized centers for cystic fibrosis (Centre de ressource et de compétences de la mucoviscidose) and remains still based on heavy symptomatic treatments. Dry powder inhaled antibiotics constitute a significant time saving for patients to whom all the care can achieve two hours daily. Since 2012, the modulators of CFTR, molecules allowing a pharmacological approach targeted according to the type of the mutations, allows a more specific approach of the disease. Ivacaftor (Kalydeco(®)) which potentialises the function of the CFTR protein expressed on the cellular surface is now available for patients with the G551D mutation. Lumacaftor is going to be tested in association with ivacaftor in patients with the F508del mutation, that is present in at least 75% of the patients. The ataluren which allows the production of a functional protein CFTR in patients with a no sense mutation is the third representing of this new therapeutic class. We presently have numerous symptomatic treatments for the cystic fibrosis care. The development of CFTR modulators, today available to a restricted number of patients treated with ivacaftor represents a very promising therapeutic avenue. It will represent probably the first step to a personalized treatment according to CFTR genotype. Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by

  12. Fetal ovarian cysts management and ovarian prognosis: a report of 82 cases.

    Fetal ovarian cysts are frequently complicated by intracystic hemorrhage without associated clinical signs, which is often secondary to ovarian torsion leading to loss of the ovary. The aim of this study was to evaluate ovarian outcome and the place of prenatal management and surgery in the first few days of life in order to save the ovary. Between January 1987 and June 2006, 82 fetal ovarian cysts in 79 patients were managed and clinically and ultrasonographically followed up for several months (median, 11 months; range, 6 months to 10 years) in all of the cases where the ovary was not removed. The ultrasonographic results regarding the ovarian parenchyma were broken down into 3 categories: follicular ovary, homogeneous ovary, and undetected ovary. Twenty-seven cysts remained simple throughout their evolution, and 55 were complicated by intracystic hemorrhage usually several weeks before birth. Overall, after disappearance of the cyst, a follicular ovary was detected in only 39% of the cases (32/82) and more often when the cyst was simple than when it presented an intracystic hemorrhage (85% vs 16.4%, chi(2), P < .0001). A review of our series confirms the poor ovarian outcome linked to ultrasonographic signs of intracystic hemorrhage. Preventive action by puncture of "simple" cysts is still being studied. The presence of a bilateral cyst can, if pulmonary maturity has been reached, be an argument for inducement of premature birth with a view to performing conservative surgery. After birth, surgery in the first few days of life is only justified if the signs of intracystic hemorrhage appeared in the period very close to birth.

    During a routine geriatric examination on a 9-yr-old, nulliparous female African warthog (Phacochoerus africanus), a severely enlarged, mixed echogenicity uterus was discovered during transabdominal ultrasound. Ovariohysterectomy (OVH) was elected and performed due to concern for a potential neoplastic condition. Postoperatively, the warthog was treated prophylactically with metoclopramide and ranitidine to promote gastrointestinal motility and prevent postoperative ileus. The gross appearance and histopathology confirmed the presence of extensive widely disseminated cystic changes consistent with cystic endometrial hyperplasia (CEH) and multiple para-ovarian cysts. Uterine pathology, including CEH, is a common condition in domestic potbellied pigs (Sus scrofa), and as a result, it is recommended to perform an OVH at an early age. The advanced uterine changes may have accounted for this animal's history of infertility. This case provides evidence that nulliparity may be associated with the development of uterine pathology in warthogs. Increased knowledge of reproductive pathology will aid in improved management strategies for breeding nondomestic suids.

  14. Cystic Endometrioma with Coexisting Fibroma Originating in a Supernumerary Ovary in the Rectovaginal Pouch

    Sakaguchi, Asumi; Kodama, Hiroko; Ogura, Kanako; Miwa, Ayako; Sugimori, Yayoi; Matuoka, Shozo; Matsumoto, Toshiharu


    A supernumerary ovary is an exceedingly rare disorder, in which the structure containing ovarian tissue is located at some distance from the normally placed ovary. 16 cases of endometriosis or tumors originating in a supernumerary ovary have been published in the English literature, but no case of coexisting endometriosis and a tumor has been published. We present the case of a 40-year-old female with cystic endometrioma with coexisting fibroma originating in a supernumerary ovary in the rectovaginal pouch. The present case is the first to be reported with coexisting endometriosis and a tumor originating in a supernumerary ovary. Our experience with this case and the results of our previous studies of rectovaginal endometriosis indicated that the possibility of originating in a supernumerary ovary shall be examined in cases of cystic endometrioma in the rectovaginal pouch.

  15. Survival of oocytes recovered from vitrified sheep ovarian tissues.

    Al-aghbari, A M; Menino, A R


    The objective of this work was to develop an effective vitrification technique for cryopreserving oocytes in sheep ovarian tissues. Ovaries were surgically recovered from 15 pubertal ewes and the ovarian cortex was cut into sections. Ovarian tissues were placed in equilibration medium consisting of 4% (v/v) ethylene glycol (EG) and 20% (v/v) FBS in TCM-199 on ice for 30 min and transferred to vitrification solution (35% EG, 5% polyvinylpyrrolidone, 0.4M trehalose and 20% FBS in TCM-199) for 5 min. Ovarian tissues were vitrified by dropping the tissue on the surface of a steel cube cooled by liquid nitrogen. Cumulus-enclosed oocyte complexes (COC) were also collected and vitrified following the procedure used for ovarian tissues. After 2-3 weeks of storage in liquid nitrogen, ovarian tissues and COC were thawed at 37 degrees C in 0.3M trehalose and COC in ovarian tissues were mechanically and enzymatically isolated. Vitrified COC and freshly collected COC were washed twice in maturation medium (TCM-199 supplemented with 0.255 mM pyruvate and 10% heat-treated estrus cow serum) and cultured in 50 microl drops of maturation medium under paraffin oil for 23-25h at 39 degrees C in a humidified atmosphere of 5% CO(2) in air. After culture, cumulus cells were removed by hyaluronidase treatment and vortexing and oocytes were fixed and stained. No significant differences were observed between vitrified oocytes, oocytes recovered from vitrified ovarian tissues and non-vitrified control oocytes in the percentage of oocytes with acceptable staining per total number of oocytes fixed or with visible chromatin per total number of oocytes with acceptable staining. However, fewer (P0.05) were observed due to treatment in the percentages of oocytes developing to metaphase II. These results demonstrate that sheep oocytes can be successfully cryopreserved by vitrification of ovarian tissues and exhibit in vitro maturation rates similar to that of vitrified and non-vitrified oocytes.

  16. Development of cystic glandular hyperplasia of the endometrium in Mullerian inhibitory substance type II receptor-pituitary tumor transforming gene transgenic mice.

    El-Naggar, Shahenda M; Malik, Mohammad T; Martin, Alvin; Moore, Joseph P; Proctor, Mary; Hamid, Tariq; Kakar, Sham S


    The pituitary tumor transforming gene (PTTG)/securin is an oncogene that is involved in cell cycle regulation and sister chromatid separation. PTTG is highly expressed in various tumors including ovarian tumors, suggesting that PTTG may play a role in ovarian tumorigenesis. Overexpression of PTTG resulted in induction of cellular transformation in vitro and tumor formation in nude mice. To ascertain PTTG function in ovarian tumorigenesis, we generated a transgenic mouse model of PTTG by cloning PTTG cDNA downstream of Mullerian inhibitory substance type II receptor gene promoter (MISIIR) in order to target the ovarian surface epithelium. By screening of transgenic animals, we identified five founders (four males and one female). Using the four male founders, we developed four transgenic lines. PTTG expression was increased in ovarian surface epithelium, ovarian granulosa cells, as well as in the pituitary gland. Transgenic females did not develop any visible ovarian tumors at 8-10 months of age; however, there was an overall increase in the corpus luteum mass in transgenic ovary, suggesting increased luteinization. These changes were associated with an increase in serum LH and testosterone levels. In addition, there was a generalized hypertrophy of the myometrium of MISIIR-PTTG transgenic uteri with cystic glandular and hyperplasia of the endometrium. Based on these results, we conclude that the overexpression of PTTG may be required to initiate precancerous conditions but is not sufficient to induce ovarian tumorigenesis and may require another partner to initiate cellular transformation.

Materials and methods: In order to induce ovarian cysts, unilateral total salpingectomy was performed in regularly menstruating adult female Wistar albino rats (n=20 between 12 and 14 weeks of age and weighing between 200 and 220 g. One month after the procedure, the abdominal cavity was opened and 14 rats (70% were found to have developed macroscopic cysts. Rats with macroscopic cysts (n=14 were assigned into two groups in a prospective and single-blinded manner: group 1 (G1 (n=7, control rats; and group 2 (G2 (n=7, 5-minute EST 95% group. Cyst diameter was measured and recorded for each rat. In G2, after whole cyst fluid was aspirated the cystic cavity was irrigated with 95% ethanol, approximately equal to half of the aspirated cyst volume, after which an interval of 5 minutes was allowed and same amount was re-aspirated and the abdominal cavity was closed. One month after this procedure, abdominal cavities were reopened and intra-abdominal adhesion scoring was performed in both groups. Cyst diameter was measured for each rat, and the right ovary was removed, fixed in 10% formaldehyde, and transported to the laboratory. A histologic assessment of the ovarian tissues was performed under light microscopy following staining with hematoxylin and eosin. Mann–Whitney U-test was used for statistical analysis. A P-level less than 0.05 was considered significant. Results

  3. Mediastinal Mature Teratoma Revealed by Empyema

    Mohammed Raoufi


    Full Text Available Teratomas are germ cell tumors, manifested with a great variety of clinical features; the most common extragonadal site is the anterior mediastinum. In this case, we report the patient with a large mature mediastinal teratoma with several components of ectodermal and endothermal epithelium. A 24-year-old female patient presented with history of persistent chest pain and progressively aggravating dyspnea for the previous 3 months. A chest X-ray showed a large opacity of the entire left hemithorax. Transcutaneous needle aspiration revealed a purulent fluid. The tube thoracostomy was introduced and the effusion was evacuated. Some weeks later, patient was seen in emergency for persistent cough and lateral chest pain. CT scan revealed a mass of the left hemithorax. The mass showed heterogeneous density, without compressing mediastinum great vessels and left hilar structures. Lipase value was elevated in needle aspiration. The patient underwent a total resection of the mediastinum mass via a left posterolateral thoracotomy. Microscopy revealed a mature teratoma with cystic structures. The patient subsequently made a full recovery. This case provide benign mediastinal teratoma with total atelectasis of left lung and elevated lipase value in needle transcutaneous aspiration; this event is explained by pancreatic component in the cystic tumor. Total removal of the tumor is adequate treatment for this type of teratoma and the prognosis is excellent.

  7. Cystic fibrosis from the gastroenterologist's perspective.

    Ooi, Chee Y; Durie, Peter R


    Cystic fibrosis is a life-limiting, recessive disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Increased survival outcomes and the multisystem nature of the disease, including the involvement of hepatobiliary and gastrointestinal tracts, now require the need for more extensive knowledge and expertise in cystic fibrosis among gastroenterologists. Manifestations are either a direct consequence of the primary defect in cystic fibrosis or a secondary complication of the disease or therapy. Adult patients with cystic fibrosis also have an increased risk of malignancy in the gastrointestinal and pancreatico-biliary tracts compared with the general population. Novel treatments that target the basic defects in the CFTR protein have emerged, but to date not much is known about their effects on the gastrointestinal and hepatobiliary systems. The introduction of such therapies has provided new opportunities for the application of intestinal endpoints in clinical trials and the understanding of underlying disease mechanisms that affect the gut in cystic fibrosis.

  8. Facial cystic lymphangioma in adults.

    Biasotto, Matteo; Clozza, Emanuele; Tirelli, Giancarlo


    Lymphangiomas are uncommon congenital malformations of the lymphatic system, generally diagnosed during childhood. These malformations are rarely seen in adults, and the literature provides poor guidelines for treatment options that must be carefully applied to the facial region. Diagnosis in adult subjects is difficult to achieve, and also management of these conditions is still challenging because they tend to infiltrate adjacent tissues, causing frequent relapses. Radical surgery is the main form of treatment, avoiding the sacrifice of function or aesthetics of the patient. Two cases of cystic lymphangioma of the facial region found in adults are described from a clinical and pathologic point of view. The aim of this article was to point out that an early recognition of cystic lymphangioma is a crucial goal to initiate a prompt treatment avoiding serious complication.

  9. [Historical compilation of cystic fibrosis].

    Navarro, Salvador


    Cystic fibrosis is the most common life-shortening recessively inherited disorder in the Caucasian population. The genetic mutation that most frequently provokes cystic fibrosis (ΔF508) appeared at least 53,000years ago. For many centuries, the disease was thought to be related to witchcraft and the "evil eye" and it was only in 1938 that Dorothy H. Andersen characterized this disorder and suspected its genetic origin. The present article reviews the pathological discoveries and diagnostic and therapeutic advances made in the last 75 years. The review ends with some considerations for the future. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    Arata Tomiyama


    Full Text Available A 14-year-old was girl admitted to our hospital with a subcutaneous mass of the occipital head. The mass had grown for 6 years, after she had sustained a head injury at the age of 6, and was located directly under a previous wound. Skull X-ray Photograph (xp, computed tomography (CT, and magnetic resonance imaging (MRI showed a bony defect and cystic changes in the skull corresponding to a subcutaneous mass. Bone scintigraphy revealed partial accumulation. The patient underwent total removal of the skull mass, and the diagnosis from the pathological findings of the cyst wall was fibrous dysplasia (FD. The radiographic findings for cystic cranial FD can be various. Progressive skull disease has been reported to be associated with head trauma, but the relationship between cranial FD and head trauma has not been previously reported. Previous studies have suggested that c-fos gene expression is a key mechanism in injury-induced FD.

  14. Control of ovarian primordial follicle activation


    The ovarian follicles develop initially from primordial follicles. The majority of ovarian primordial follicles are maintained quiescently as a reserve for the reproductive life span. Only a few of them are activated and develop to an advanced follicular stage. The maintenance of dormancy and activation of primordial follicles are controlled by coordinated actions of a suppressor/activator with close communications with somatic cells and intra-oocyte signaling pathways. Many growth factors and signaling pathways have been identified and the transforming growth factor-beta superfamily plays important roles in early folliculogenesis. However, the mechanism of maintaining the dormancy and survival of primordial follicles has remained unknown for decades. Recently, since the first finding that all primordial follicles are activated prematurely in mice deficient forkhead box O3a, phosphatidylinositol 3 kinase/phosphatase and tensin homolog (PTEN) signaling pathway was reported to be important in the regulation of dormancy and initial follicular activation. With these informations on early folliculogenesis, clinical application can be expected such as in vitro maturation of immature oocytes or in vitro activation of follicles by PTEN inhibitor in cryopreserved ovarian cortical tissues for fertility preservation.

  16. Diagnosis and management of an immature teratoma during ovarian stimulation: a case report

    Douay-Hauser Nathalie


    Full Text Available Abstract Introduction The discovery of a mature teratoma (dermoid cyst of the ovary during ovarian stimulation is not a rare event. Conversely, we could not find any reported cases of immature teratoma in such a situation. Clinical and ultrasound arguments for this immature form are scarcely or poorly evaluated. Case Presentation We describe the case of a 31-year-old Caucasian woman with primary infertility, who developed an immature teratoma during an in vitro fertilization ovarian stimulation cycle. Conclusions Ultrasound signs of an atypical cyst during ovarian stimulation allowed us to adopt a careful medical attitude and to adapt the required surgical oncological treatment.

  17. GnRH Analogues in the Prevention of Ovarian Hyperstimulation Syndrome

    Alama, Pilar; Bellver, Jose; Vidal, Carmen; Giles, Juan


    The GnRH analogue (agonist and antagonist GnRH) changed ovarian stimulation. On the one hand, it improved chances of pregnancy to obtain more oocytes and better embryos. This leads to an ovarian hyper-response, which can be complicated by the ovarian hyperstimulation syndrome (OHSS). On the other hand, the GnRH analogue can prevent the incidence of OHSS: GnRH antagonist protocols, GnRH agonist for triggering final oocyte maturation, either together or separately, coasting, and the GnRH analogue may prove useful for avoiding OHSS in high-risk patients. We review these topics in this article. PMID:23825982

    AbstractObjective:To discuss the value of 3.0 tesila MRI in the diagnosis of cystic-solid masses of appendix. And, to analyse the causes of misdiagnosis of common accessories lesions like mature ovarian cystic teratoma, endometrisis cysts, cystadenoma, borderline cystadenoma and ovarian canner.Materials and Methods:A total of 125 lesions were collected in this study, all lesions were diagnosed as cystic-solid masses of appendix by postoperative pathology. The MRI manifestations were analyzed retrospectively, and the causes of misdiagnosis were summarized.Results:There were 84 benign lesions, 25 borderline lesions, and 16 maglignant lesions. Among all of the lesions, there were 104 lesions (83.2%) were diagnosed accurately by MRI, 21 lesions (16.8%) were misdiagnosed. Thirteen in 16 maglignant lesions of MRI staging were coincide well with pathological staging, however, 3 lesions of MRI staging was lighter than pathological staging. The ADC value was statistically significant among benign (1.325×10-3 mm/s), borderline (1.081×10-3 mm/s) and malignant lesions (0.928×10-3 mm/s) groups (P<0.05).Conclusions:Although benign and malignant (especially the borderline) cystic-solid lesions of appendix on MRI have certain overlap, the diagnostive value for cystic-solid masses of appendix on 3.0 tesila MR was high. Some of the cystic-solid lesions have particular characteristics in MR imagings.

  19. Ovarian tubercular abscess mimicking ovarian carcinoma: A rare case report

    Abinash Agarwala


    Full Text Available Although genito-urinary tuberculosis is common, reports of isolated ovarian tubercular abscess are rare. Ovarian tubercular abscess may mimics that of an ovarian tumor, leading to diagnostic difficulties. We reported a case report of 35 years woman presented with chronic pain abdomen, weight loss, low-grade fever and a right ovarian mass on ultrasound, with a significantly elevated CA-125 level. On clinical and radiological evidence, diagnosis of ovarian carcinoma was made, and laparotomy was performed with resection of the ovary. Postoperative specimen sent for histological examination that revealed classic epithelioid granuloma and acid-fast bacilli were present in Ziehl-Neelsen stain. Patient was put on antitubercular regimen from our Dots center. She is improving clinical after taking antitubercular drug and is on regular follow up at our chest outpatient department. Ovarian tubercular abscess is common in young women living in endemic zones, but case report of isolated tubercular abscess is rarely reported. CA-125 can be raised in both ovarian tubercular abscess and ovarian carcinoma, and only imaging is not always conclusive. Laparotomy followed by tissue diagnosis can be helpful in this situation. As the prognosis and treatment outcome of ovarian tubercular abscess and ovarian carcinoma is different, proper diagnosis by laparotomy should be done. Early diagnosis of ovarian tubercular abscess is vital as untreated disease can lead to infertility.

  20. A Case Report of an Incidentally Diagnosed Blind-ending Bifid Ureter in a Patient with Ovarian Cancer.

    Enkhbaatar, Nandin E; Ono, Shun; Ichikawa, Tamaki; Hoshi, Akio; Terachi, Toshiro; Ogura, Go; Kondo, Yusuke; Ikeda, Masae; Imai, Yutaka


    A 58-year-old Japanese female was admitted to our hospital for treatment of ovarian cancer. She had no urinary tract symptoms at the time of presentation. Preoperative CT (Computed Tomography) was performed for surgical planning, and it revealed two left-sided ureters including a short ureter with a blind, cystic ending and a short ureter joined to the main ureter before entering into the bladder. On CT urography, these radiological findings were compatible with a blind-ending bifid ureter. Preoperatively, a double J stent was inserted into the normal left ureter, and then the blind-ending bifid ureter was resected before an ovarian cancer operation.

  2. Outcome in cystic fibrosis liver disease.

    Rowland, Marion


    Evidence suggests that cystic fibrosis liver disease (CFLD) does not affect mortality or morbidity in patients with cystic fibrosis (CF). The importance of gender and age in outcome in CF makes selection of an appropriate comparison group central to the interpretation of any differences in mortality and morbidity in patients with CFLD.

  7. Maturity and maturity models in lean construction

    Claus Nesensohn


    Full Text Available In recent years there has been an increasing interest in maturity models in management-related disciplines; which reflects a growing recognition that becoming more mature and having a model to guide the route to maturity can help organisations in managing major transformational change. Lean Construction (LC is an increasingly important improvement approach that organisations seek to embed. This study explores how to apply the maturity models to LC. Hence the attitudes, opinions and experiences of key industry informants with high levels of knowledge of LC were investigated. To achieve this, a review of maturity models was conducted, and data for the analysis was collected through a sequential process involving three methods. First a group interview with seven key informants. Second a follow up discussion with the same individuals to investigate some of the issues raised in more depth. Third an online discussion held via LinkedIn in which members shared their views on some of the results. Overall, we found that there is a lack of common understanding as to what maturity means in LC, though there is general agreement that the concept of maturity is a suitable one to reflect the path of evolution for LC within organisations.

  9. Successful fertility preservation following ovarian tissue vitrification in patients with primary ovarian insufficiency.

    Suzuki, Nao; Yoshioka, Nobuhito; Takae, Seido; Sugishita, Yodo; Tamura, Midori; Hashimoto, Shu; Morimoto, Yoshiharu; Kawamura, Kazuhiro


    Is ovarian tissue cryopreservation using vitrification followed by in vitro activation (IVA) of dormant follicles a potential approach for infertility treatment of patients with primary ovarian insufficiency (POI)? Our vitrification approach followed by IVA treatment is a potential infertility therapy for POI patients whose ovaries contain residual follicles. Akt (protein kinase B) stimulators [PTEN (phosphatase with TENsin homology deleted in chromosome 10) inhibitor and phosphatidyinositol-3-kinase (PI3 kinase) stimulator] activate dormant primordial follicles in vitro and ovarian fragmentation disrupts the Hippo signaling pathway, leading to the promotion of follicle growth. We treated POI patients with a combination of ovarian vitrification, fragmentation and drug treatment, followed by auto-transplantation, and reported successful follicle growth and pregnancies. Prospective clinical study of 37 infertile women with POI between 12 August 2011 and 1 November 2013. We enrolled 10 new patients since the previous publication. POI patients were originally selected based on a history of amenorrhea for more than 1 year and elevated serum FSH levels of >40 mIU/ml (n = 31) but this was later changed to >4 months, age 35 mIU/ml (n = 6) (mean 71.8 ± 30.8, range 35.5-197.6) so as to include patients with a shorter duration of amenorrhea. Under laparoscopic surgery, ovariectomy was performed and ovarian cortices were dissected into strips for vitrification. Some pieces were examined histologically. After warming, two to three strips were fragmented into smaller cubes before culturing with Akt stimulators for 2 days. After washing, ovarian cubes were transplanted beneath the serosa of Fallopian tubes under laparoscopic surgery. Follicle growth was monitored by ultrasound and serum estrogen levels. After oocyte retrieval from mature follicles, IVF was performed. Among 37 patients, 54% had residual follicles based on histology. Among patients with follicles, 9 out of 20

    Cysts are commonly seen on CT scans of the lungs, and diagnosis can be challenging. Clinical and radiographic features combined with a multidisciplinary approach may help differentiate among various disease entities, allowing correct diagnosis. It is important to distinguish cysts from cavities because they each have distinct etiologies and associated clinical disorders. Conditions such as emphysema, and cystic bronchiectasis may also mimic cystic disease. A simplified classification of cysts is proposed. Cysts can occur in greater profusion in the subpleural areas, when they typically represent paraseptal emphysema, bullae, or honeycombing. Cysts that are present in the lung parenchyma but away from subpleural areas may be present without any other abnormalities on high-resolution CT scans. These are further categorized into solitary or multifocal/diffuse cysts. Solitary cysts may be incidentally discovered and may be an age related phenomenon or may be a remnant of prior trauma or infection. Multifocal/diffuse cysts can occur with lymphoid interstitial pneumonia, Birt-Hogg-Dubé syndrome, tracheobronchial papillomatosis, or primary and metastatic cancers. Multifocal/diffuse cysts may be associated with nodules (lymphoid interstitial pneumonia, light-chain deposition disease, amyloidosis, and Langerhans cell histiocytosis) or with ground-glass opacities (Pneumocystis jirovecii pneumonia and desquamative interstitial pneumonia). Using the results of the high-resolution CT scans as a starting point, and incorporating the patient's clinical history, physical examination, and laboratory findings, is likely to narrow the differential diagnosis of cystic lesions considerably.

  11. Muscular cystic hydatidosis: case report

    Naspetti Riccardo


    Full Text Available Abstract Background Hydatidosis is a zoonosis caused by Echinococcus granulosus, and ingesting eggs released through the faeces from infected dogs infects humans. The location of the hydatid cysts is mostly hepatic and/or pulmonary, whereas musculoskeletal hydatidosis is very rare. Case presentation We report an unusual case of primary muscular hydatidosis in proximity of the big adductor in a young Sicilian man. The patient, 34 years old, was admitted to the Department of Infectious and Tropical Diseases for ultrasonographic detection, with successive confirmation by magnetic resonance imaging, of an ovular mass (13 × 8 cm in the big adductor of the left thigh, cyst-like, and containing several small cystic formations. Serological tests for hydatidosis gave negative results. A second drawing of blood was done 10 days after the first one and showed an increase in the antibody titer for hydatidosis. The patient was submitted to surgical excision of the lesion with perioperatory prophylaxis with albendazole. The histopathological examination of the bioptic material was not diriment in the diagnosis, therefore further tests were performed: additional serological tests for hydatidosis for the evaluation of IgE and IgG serotype (Western Blot and REAST, and molecular analysis of the excised material. These more specific serological tests gave positive results for hydatidosis, and the sequencing of the polymerase chain reaction products from the cyst evidenced E. granulosus DNA, genotype G1. Any post-surgery complications was observed during 6 following months. Conclusion Cystic hydatidosis should always be considered in the differential diagnosis of any cystic mass, regardless of its location, also in epidemiological contests less suggestive of the disease. The diagnosis should be achieved by taking into consideration the clinical aspects, the epidemiology of the disease, the imaging and immunological tests but, as demonstrated in this case, without

  12. Multicystic peritoneal mesothelioma after fertility-sparing surgery for an ovarian tumor of borderline malignancy: A case report

    Hidetaka Nomura


    Full Text Available We report a case of a 19-year-old woman with multicystic peritoneal mesothelioma (MCPM who had previously undergone left adnexectomy due to an ovarian tumor of borderline malignancy at the age of 17 years. Follow-up imaging studies after adnexectomy revealed multiple cystic lesions of increasing size and number, suggesting recurrence of the tumor. Diagnostic laparoscopic surgery was performed, and the cystic lesion was pathologically determined to be MCPM. To our knowledge, this is the first report of MCPM diagnosed and successfully treated by laparoscopic surgery during the course of follow-up for an ovarian tumor. It is important to recognize that MCPM can occur in patients who have previously undergone abdominal surgery, and laparoscopic surgery is recommended for patients of reproductive age, because of the potential risk of infertility associated with extensive pelvic surgery.

  13. Use of medroxyprogesterone acetate in women with ovarian endometriosis undergoing controlled ovarian hyperstimulation for in vitro fertilization.

    Guo, Haiyan; Wang, Yun; Chen, Qiuju; Chai, Weiran; Sun, Lihua; Ai, Ai; Fu, Yonglun; Lyu, Qifeng; Kuang, Yanping


    This study investigated the use of medroxyprogesterone acetate (MPA) or a short protocol for controlled ovarian hyperstimulation (COH) in patients with advanced endometriosis who have normal ovarian function, and to compare cycle characteristics and pregnancy outcomes after frozen-thawed embryo transfer (FET). This was a retrospective case-control study of 244 patients with advanced endometriosis undering COH. The patients were allocated to three groups: the surgery group with MPA COH (62 patients, 71 IVF/ICSI cycles, 78 FET cycles); the aspiration group with MPA COH (85 patients had ovarian "chocolate" cysts (>3 cm) aspirated, 90 IVF/ICSI cycles, 76 FET cycles); and the short protocol group (97 patients, 101 IVF/ICSI cycles, 51 FET cycles). The results showed that higher rates of mature oocyte, D3 high quality embryo, hMG dose were observed in the two study groups using MPA compared with the short protocol. The number of >10-14 mm follicles on the trigger day, D3 top-quality embryos, viable embryos, rates of cancellation, fertilization, implantation, pregnancy outcomes were similar among the three groups. The oocytes, embryos, and pregnancy outcomes were not influenced by endometrioma surgery or presence of endometrioma. MPA COH could be effective for women with ovarian advanced endometriosis who had normal ovarian function.

  14. Endocrine Disorders in Cystic Fibrosis.

    Blackman, Scott M; Tangpricha, Vin


    Cystic fibrosis is frequently complicated by endocrine disorders. Diabetes can be expected to affect most with CF and pancreatic insufficiency and varies widely in age of onset, but early identification and treatment improve morbidity and mortality. Short stature can be exacerbated by relative delay of puberty and by use of inhaled corticosteroids. Bone disease in CF causes fragility fractures and should be assessed by monitoring bone mineral density and optimizing vitamin D status. Detecting and managing endocrine complications in CF can reduce morbidity and mortality in CF. These complications can be expected to become more common as the CF population ages.

During a period of 20 years (1983-2003), a total of 364 cases of echinococcosis, including 263 CE and 101 AE cases were diagnosed at Hydatidos Research Laboratory (HRL), Basic Medical College, Lanzhou University, China. Of them, 5 cases of osseous CE (1.37%) were encountered and now reported as follows.

  16. Cystic Lesions of the Mediastinum.

    Vargas, Daniel; Suby-Long, Thomas; Restrepo, Carlos S


    Cystic lesions are commonly seen in the mediastinum, and they may arise from virtually any organ. The vast majority of these lesions are benign and result in no symptoms. When large, cysts may produce symptoms related to compression of adjacent structures. The most common mediastinal cysts are pericardial and foregut duplication cysts. Both computed tomography and magnetic resonance are routinely used to evaluate these lesions. Although computed tomography offers superior spatial resolution, magnetic resonance is useful in differentiating cysts that contain proteinaceous material from solid lesions. Occasionally, cysts arise from solid lesions, such as thymoma or teratoma. Although cysts are alike in appearance, location helps narrowing the differential diagnoses.

  1. Teratoma of the anterior mediastinum presenting as a cystic neck mass: a case report

    Agarwal Gaurav


    Full Text Available Abstract Introduction Teratomas of anterior mediastinum are rare tumors and are often slow growing, asymptomatic and detected incidentally on chest imaging. Results of surgical resection are very satisfactory. Case presentation A 19-years old male presented with an asymptomatic cystic neck mass. X-ray and CT scan of chest and neck showed an extrathyroidal multi-septate, predominantly cystic neck mass, that was continuous with a solid intrathoracic mass extending up to the level of right atrium and which contained areas of calcification and cystic necrosis. The mediastinal structures did not show any features of compression or infiltration. Fine needle aspiration cytology from the neck mass was suggestive of a dermoid cyst. In view of the extent and uncertain pathological nature of the tumor, it was excised via a combined cervical and trans-sternal route. Histo-pathology of the resected specimen confirmed the diagnosis of a mature cystic teratoma. The patient made an uneventful recovery, and after five years of follow-up, he has been symptom free with no clinical or radiological evidence of recurrent disease. We discuss the role of imaging and the need for surgical treatment to avoid possible catastrophic complications in patients with cervical and mediastinal masses of uncertain histological nature. Conclusion A mediastinal teratoma may rarely present as a cystic neck swelling due to its cephalad extension. This entity needs to be considered in cases where clinical and investigative work-up fail to provide a convincing clue to a primary neck pathology as cause of a cystic neck swelling.

  2. Assessment of Relationship Between IGF-I Concentration Before Parturition and Postpartum Endometritis and Ovarian Cysts in Dairy Cattle

    Mohammad Rahim AHMADI


    Full Text Available This study was carried out to assess the IGF-I, non-esterified fatty acids (NEFA, beta hydroxybutyrate (BHB and glucose concentrations during the peripartum period of dairy cows in normal condition, and cows with endometritis puerperalis and cystic ovarian disease. The study was conducted on 87 lactating Holstein cows (parity: 1-7 in the 9th month of pregnancy in Shiraz, Iran. Blood samples were collected every 2 weeks from 2 weeks before until 6 weeks after calving. Two, four and six weeks after calving, palpation of the reproductive tract was performed. Cows were first inspected for the presence of fresh abnormal discharge on the vulva, perineum, or tail then those were examined intra-vaginally. Following inspection, ultrasonographic assessment of uterus and ovaries was also performed and ovarian structures (palpable follicle, CL and cyst were scanned. Prepartum IGF-I concentration was significantly lower in cows that developed cystic ovaries than non-cystic (35.89±9.09 versus 41.99±3.65 μg/L and cows with clinical endometritis early postpartum than normal cows (36.65±5.38 versus 43.64±4.32 μg/L. Calving-first service interval and ovarian cycle resumption after calving was significantly shorter for cows without clinical endometritis than cows with clinical endometritis. In conclusion, prepartum IGF-I concentration was the main factor associated with occurrence of endometritis and cystic ovarian disease after calving and it was a notable feature of the current study.

  5. Cystic Fibrosis: Brazilian ENT Experience

    Tania Sih


    Full Text Available Most published studies about Cystic Fibrosis (CF are European or North American. There are still few publications about the characteristics of fibrocystic populations in developing countries. The incidence of cystic fibrosis (CF in Brazil varies among different regions (1 : 10,000 in Minas Gerais, 1 : 9,500 in Paraná, 1 : 8,700 in Santa Catarina, and 1 : 1600 in Rio Grande do Sul. The prevalence of the DF508 mutation also varies according to population: 33% in Sao Paulo, 49% in Rio Grande do Sul, 27% in Santa Catarina, and 52% in Minas Gerais. Cough and nasal obstruction are the most common symptoms. The variation in nasal polyposis prevalence may be explained by population genotypic characteristics in a country that spans a continent. Findings on nasal endoscopy and computed tomography (CT have better correlation than do this information compared with surgical and clinical history. Microbiologic studies suggest a high level of early contamination of the airways. Sensorineural hearing loss (SNHL occurs in these patients as a result of ototoxic antibiotics. The data compiled in this paper is useful, but also lead to the general agreement that more research would be welcome due to the unique characteristics of this country.

  6. Cystic lymphangioma of the pancreas

    Radoje B Colovic; Nikica M Grubor; Marjan T Micev; Henry Dushan E Atkinson; Vitomir I Rankovic; Mihajlo M Jagodic


    Lymphangioma of the pancreas is an extremely rare benign turnout of lymphatic origin, with fewer than 60 published cases. Histologically, it is polycystic, with the cysts separated by thin septa and lined with endothelial cells. Though congenital, it can affect all age groups, and occurs more frequently in females. Patients usually present with epigastric pain and an associated palpable mass. Complete excision is curative, even though, depending on the tumour location, surgery may be simple or involve extensive pancreatic resection and anastomoses. The authors present a 49-year-old woman in whom a polycystic septated mass, 35 mm × 35 mm in size, was discovered by ultrasonography (US) in the body of the pancreas during investigations for epigastric pain and nausea. At surgery, a well circumscribed polycystic tumor was completely excised, with preservation of the pancreatic duct. The postoperative recovery was uneventful. Histology confirmed a microcystic lymphangioma of the pancreas. Immunohistochemistry showed cystic endothelial cells reactivity to factor Ⅷ -RA (++), CD31 (+++) and CD34 (-). Postoperatively, abdominal pain disappeared and the patient remained symptomfree for 12 mo until now. Although extremely rare, lymphangioma of the pancreas should be taken into consideration as a differential diagnosis of a pancreatic cystic lesion, especially in women.

  7. [Cystic fibrosis and other channelopathies].

    Edelman, A; Saussereau, E


    Mutations in cystic fibrosis transmembrane conductance regulator gene, CFTR, are responsible for cystic fibrosis, CF, a channelopathie. CFTR protein is a multifunctional protein with a main function of Cl(-) channel. CFTR is expressed in epithelia (upper airways, intestine, pancreas etc.). In the first part of this revue, we describe the main properties of CFTR underlying that it is not only a Cl(-) channel protein but also a multifunctional protein. We present a hypothesis which postulates that CFTR is a hub protein interacting with more than 140 proteins, and through these interactions regulates a number of functions which are abnormal in CF (ion transport, inflammation etc.). In the second part of the revue we briefly present a selection of other epithelial channelopathies due to mutations in genes of other Cl(-) or cation channels. Of note, these channels either interacts with CFTR or are considered as alternative channels in CF, and, as such, are targets for pharmacotherapies. We want to leave the reader with a message that to investigate channalopathies, to dissect the molecular mechanisms underlying channels'activity, allow not only to better understand basic mechanisms of channel regulation but in fine, to propose new targets for pharmacotherapies.

  8. Intraductal Oncocytic Papillary Neoplasm Having Clinical Characteristics of Mucinous Cystic Neoplasm and a Benign Histology

    Takatomi Oku


    Full Text Available Context An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor which was first described by Adsay et al. in 1996. It has been defined as a new subgroup of IPMN. Case report We report the case of a 76-year-old woman who presented with nausea. Imaging studies revealed a cystic mass in the body of the pancreas. She underwent a successful distal pancreatectomy and splenectomy, and has subsequently remained well. Microscopically, the cyst was lined by columnar epithelium similar to pancreatic duct epithelium, and the nodular projection consisted of arborizing papillary structures, lined by plump cells with abundant eosinophilic cytoplasm. These eosinophilic cells were immunohistochemically positively stained with anti-mitochondrial antibody. The cellular atypism was mild and the proliferating index was low, compatible with adenoma of an intraductal oncocytic papillary neoplasm. Although no ovarian type stroma was identified, in our case, no communication to main pancreatic duct (located in the pancreatic body and rapid growth by intracystic hemorrhage were clinical characteristics of a mucinous cystic neoplasm, but not IPMN. Conclusion With only 17 cases reported to date, the clinical and pathological details of an intraductal oncocytic papillary neoplasm are still unclear. We herein add one case with different characteristics from those of the past reports. To our knowledge, this is the first case report of an intraductal oncocytic papillary neoplasm with the clinical characteristics of a mucinous cystic neoplasm.

    Objective. To study the sonographic features and patterns of cystic renal carcinomas. Methods. Thirteen cases of cystic renal carcinoma confirmed by operation and pathology were examined by ultrasonography, and the cystic walls, septa and solid mural nodules were studied. Results. Solid mural nodules of some cases and irregular thickening of the cystic walls and septa were characteristic findings for the ultrasonic diagnosis of cystic renal carcinomas. According to their pathologic mechanisms and sonographic features, cystic renal carcinomas were classified into 3 patterns: unilocular cystic mass, multiloculated cystic mass and cystic-solid mass. Conclusions. Typical cystic renal carcinomas can be well diagnosed, while atypical cases may be misdiagnosed as benign renal cysts by ultrasonography. Color Doppler ultrasonography and needle aspiration guided by ultrasonography are helpful in the diagnosis of these atypical cases.

    Park, Chan Woo; Lee, Sun Hee; Yang, Kwang Moon; Lee, In Ho; Lim, Kyung Teak; Lee, Ki Heon; Kim, Tae Jin


    The aim of this study was to report a case series of in vitro matured (IVM) oocyte freezing in gynecologic cancer patients undergoing radical surgery under time constraints as an option for fertility preservation (FP). Case series report. University-based in vitro fertilization center. Six gynecologic cancer patients who were scheduled to undergo radical surgery the next day were referred for FP. The patients had endometrial (n=2), ovarian (n=3), and double primary endometrial and ovarian (n=1) cancer. Ex vivo retrieval of immature oocytes from macroscopically normal ovarian tissue was followed by mature oocyte freezing after IVM or embryo freezing with intracytoplasmic sperm injection. A total of 53 oocytes were retrieved from five patients, with a mean of 10.6 oocytes per patient. After IVM, a total of 36 mature oocytes were obtained, demonstrating a 67.9% maturation rate. With regard to the ovarian cancer patients, seven IVM oocytes were frozen from patient 3, who had stage IC cancer, whereas one IVM oocyte was frozen from patient 4, who had stage IV cancer despite being of a similar age. With regard to the endometrial cancer patients, 15 IVM oocytes from patient 1 were frozen. Five embryos were frozen after the fertilization of IVM oocytes from patient 6. Immature oocytes can be successfully retrieved ex vivo from macroscopically normal ovarian tissue before radical surgery. IVM oocyte freezing provides a possible FP option in patients with advanced-stage endometrial or ovarian cancer without the risk of cancer cell spillage or time delays.

  14. Mediastinal Cystic Lymphangioma in a Patient with Situs Inversus Totalis

    Teruya Komatsu


    Full Text Available We present a case of cystic lymphangioma of the mediastinum complicated with situs inversus totalis. The 70-year-old man underwent thoracoscopic resection of a mediastinal cystic tumor, which was diagnosed as cystic lymphangioma. Cystic lymphangiomas are congenital cystic abnormalities of the lymphatic system. The head and neck area is often involved while the mediastinum is rarely affected. The rarity of this case is further attributed to the coexistence of situs inversus totalis.

    Yun, Tae Jun; Kim, Myung Jun; Han, Seok Joo; Lee, Mi Jung [Severance Children' s Hospital, Yonsei University, College of Medicine, Seoul(Korea, Republic of)


    Perinatal detection of neonatal suprarenal masses has increased. Here, we report an unusual case of an adrenal cystic neuroblastoma that presented as a purely cystic lesion upon initial postnatal ultrasonography (US) and showed rapid evolution to a mixed cystic and solid mass during follow-up US and MRI. We suggest a short-term (two weeks) follow-up US for neonatal adrenal cystic lesions, even if they appear as purely cystic.

  16. Plasma oxidative stress biomarkers and progesterone profiles in a dairy cow diagnosed with an ovarian follicular cyst.

    Talukder, S; Ingenhoff, L; Kerrisk, K L; Celi, P


    This study was conducted to examine the oxidative stress biomarkers in a cow diagnosed with a follicular cyst in her left ovary. Progesterone (P4) and plasma oxidative stress status was measured in 13 Holstein cows after synchronization of oestrus with controlled internal drug release (CIDR) and prostaglandinF2α (PGF2α) protocol. The presence and size of ovarian structures were monitored by transrectal ultrasound at 4 hourly intervals. Of the 13 cows, 12 were monitored until ovulation was detected and recorded, whereas one cow failed to ovulate and developed a follicular cyst. Oxidative stress biomarkers; reactive oxygen metabolites (ROMs), biological antioxidant potential (BAP), oxidative stress index (OSI), glutathione (GSH), ceruloplasmin and advanced oxidation protein products (AOPP) were measured in the cystic cow and compared to those of the 12 ovulated cows and are referred to as higher or lower if they are outside the mean ± standard error of mean of those of ovulated cows. The cystic cow had lower ROMs and OSI between 36 and 84 h after PGF2α injection and at 9 h, from 36 to 60 h after PGF2α injection respectively. On the other hand, antioxidant (BAP and GSH) was higher in the cystic cow compared to her ovulated herd mates. The observed imbalance between oxidant and antioxidant might have disrupted the physiological events for ovulation to occur, leading to cystic ovarian disease.

  17. Artery to Cystic Duct: A Consistent Branch of Cystic Artery Seen in Laparoscopic Cholecystectomy

    Arshad Rashid


    Full Text Available Uncontrolled arterial bleeding during laparoscopic cholecystectomy is a serious problem and may increase the risk of bile duct damage. Therefore, accurate identification of the anatomy of the cystic artery is very important. Cystic artery is notoriously known to have a highly variable branching pattern. We reviewed the anatomy of the cystic artery and its branch to cystic duct as seen through the video laparoscope. A single artery to cystic duct with the classical “H-configuration” was demonstrated in 161 (91.47% patients. This branch may cause troublesome bleeding during laparoscopic dissection in the hepatobiliary triangle. Careful identification of artery to cystic duct is helpful in the proper dissection of Calot’s triangle as it reduces the chances of hemorrhage and thus may also be helpful in prevention of extrahepatic biliary radical injuries.

  18. Ovarian Torsion in the Third Trimester of Pregnancy Leading to Iatrogenic Preterm Delivery

    Evangelia Vlachodimitropoulou Koumoutsea


    Full Text Available Ovarian torsion in the third trimester of pregnancy leading to a midline laparotomy and caesarean section for the delivery of a preterm baby is an uncommon event. As the woman is likely to present with nonspecific symptoms of lower abdominal pain, nausea, and vomiting, ovarian torsion can often be misdiagnosed as appendicitis or preterm labour. Treatment and the opportunity to preserve the tube and ovary may consequently be delayed. We report the case of a multiparous woman who had undergone two previous caesarean sections at term, presenting at 35 weeks of gestation with a presumptive diagnosis of acute appendicitis. Ultrasonography described a cystic lesion 6 × 3 cm in the right adnexa, potentially a degenerating fibroid or a torted right ovary. MRI of the pelvis was unable to provide further clarity. The patient was managed by midline laparotomy and simultaneous detorsion of the ovarian pedicle and ovarian cystectomy together with caesarean section of a preterm infant. This report describes that prompt recognition and ensuring intraoperative access can achieve a successful maternal and fetal outcome in this rare and difficult scenario. Furthermore, we would like to emphasise that the risk for a pregnant woman and her newborn could be reduced by earlier diagnosis and management of ovarian masses (Krishnan et al., 2011.

  19. Cystic Pheochromocytoma Presenting as Adrenal Cyst

    Abdulsalam, Mohammed Shafi; Satish, Priyanka; Janakiraman, Raghunath Keddy; Singh, Shivshankar


    Pheochromocytomas are usually solid tumours. But it can present as cystic lesions in the adrenal gland. Cystic lesions in adrenal gland with hypertension needs attention to rule out pheochromocytoma. If ignored, it may lead to hypertensive emergency, multisystem crisis and death. Early diagnosis with biochemistry, Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) of abdomen, proper functional imaging like Meta Iodo Benzyl Guanidine (MIBG) scan is essential. Proper preoperative preparation is important to prevent hypertensive crisis during and after surgery. We are reporting a case of cystic pheochromocytoma in a young male. PMID:28050427

  2. Heart involvement in cystic fibrosis: A specific cystic fibrosis-related myocardial changes?

    Labombarda, Fabien; Saloux, Eric; Brouard, Jacques; Bergot, Emmanuel; Milliez, Paul


    Cystic fibrosis is a complex multi-systemic chronic disease characterized by progressive organ dysfunction with development of fibrosis, possibly affecting the heart. Over the last four decades pathological, experimental, and clinical evidence points towards the existence of a specific myocardial involvement in cystic fibrosis. Multi-modality cardiac imaging, especially recent echocardiographic techniques, evidenced diastolic and/or systolic ventricular dysfunction in cystic fibrosis leading to the concept of a cystic fibrosis-related cardiomyopathy. Hypoxemia and inflammation are among the most important factors for heart involvement in cystic fibrosis. Cystic Fibrosis Transmembrane Regulator was found to be involved in the regulation of cardiomyocyte contraction and may also account for cystic fibrosis-related myocardial dysfunction. This review, mainly focused on echocardiographic studies, seeks to synthesize the existing literature for and against the existence of heart involvement in cystic fibrosis, its mechanisms and prognostic implications. Careful investigation of the heart function may be helpful for risk stratification and therapeutic decisions in patients with cystic fibrosis.

    Purpose: The purpose of this study was to assess MR imaging findings of ovarian fibromas with emphasis on intratumoral cyst formation. Materials and methods: MR images with a 1.5-T unit obtained in 17 consecutive patients (age range, 18–87 years; mean age, 58 years) with 17 histologically proven ovarian fibromas were retrospectively reviewed for the size, configuration, signal intensity of solid components, and presence of cystic degeneration and edema within tumor. Size, number, and location of intratumoral cysts were also assessed. Results: The maximum diameter of tumors ranged from 3.3 to 19.1 cm (mean, 10.9 cm). Seven (41%) tumors were multinodular. On T2-weighted images, solid components of tumors were heterogeneously mixed hypo- and hyperintensity in 16 (94%) tumors. Nine (53%) tumors demonstrated cysts and 16 (94%) demonstrated edema within tumor. The maximum diameter of the largest cysts ranged from 1.0 to 13.2 cm (mean, 6.4 cm), and the number of cysts per tumor ranged from 1 to 60 (mean, 15.6). Of the nine tumors with cystic formation, the predominant location of the cysts was peripheral in five (56%), exophytic in two (22%), central (11%) in one, and diffuse in one (11%). Conclusion: Peripheral or exophytic cyst formation may be characteristic MR imaging features with ovarian fibromas.

  4. Poor ovarian reserve

    Padma Rekha Jirge


    Full Text Available Poor ovarian reserve (POR is an important limiting factor for the success of any treatment modality for infertility. It indicates a reduction in quantity and quality of oocytes in women of reproductive age group. It may be age related as seen in advanced years of reproductive life or may occur in young women due to diverse etiological factors. Evaluating ovarian reserve and individualizing the therapeutic strategies are very important for optimizing the success rate. Majority or women with POR need to undergo in vitro fertilization to achieve pregnancy. However, pregnancy rate remains low despite a plethora of interventions and is associated with high pregnancy loss. Early detection and active management are essential to minimize the need for egg donation in these women.

  5. Ovarian hormones and obesity.

    Leeners, Brigitte; Geary, Nori; Tobler, Philippe N; Asarian, Lori


    Obesity is caused by an imbalance between energy intake, i.e. eating and energy expenditure (EE). Severe obesity is more prevalent in women than men worldwide, and obesity pathophysiology and the resultant obesity-related disease risks differ in women and men. The underlying mechanisms are largely unknown. Pre-clinical and clinical research indicate that ovarian hormones may play a major role. We systematically reviewed the clinical and pre-clinical literature on the effects of ovarian hormones on the physiology of adipose tissue (AT) and the regulation of AT mass by energy intake and EE. Articles in English indexed in PubMed through January 2016 were searched using keywords related to: (i) reproductive hormones, (ii) weight regulation and (iii) central nervous system. We sought to identify emerging research foci with clinical translational potential rather than to provide a comprehensive review. We find that estrogens play a leading role in the causes and consequences of female obesity. With respect to adiposity, estrogens synergize with AT genes to increase gluteofemoral subcutaneous AT mass and decrease central AT mass in reproductive-age women, which leads to protective cardiometabolic effects. Loss of estrogens after menopause, independent of aging, increases total AT mass and decreases lean body mass, so that there is little net effect on body weight. Menopause also partially reverses women's protective AT distribution. These effects can be counteracted by estrogen treatment. With respect to eating, increasing estrogen levels progressively decrease eating during the follicular and peri-ovulatory phases of the menstrual cycle. Progestin levels are associated with eating during the luteal phase, but there does not appear to be a causal relationship. Progestins may increase binge eating and eating stimulated by negative emotional states during the luteal phase. Pre-clinical research indicates that one mechanism for the pre-ovulatory decrease in eating is a

  6. Cystic fibrosis-related diabetes

    Andersen, Henrik U; Lanng, Susanne; Pressler, Tania


    OBJECTIVE: Cystic fibrosis (CF)-related diabetes has been regarded as a mild form of diabetes with a low risk of severe diabetes complications. The prevalence of CF-related diabetes increases with age, resulting in a 50% prevalence of diabetes at age 30 years. We sought to investigate whether...... microvascular complications in CF-related diabetes appear with a relevant frequency. RESEARCH DESIGN AND METHODS: Thirty-eight patients aged 30 (range 18-55) years with CF-related diabetes for 20 (0-31) years were screened for diabetes complications. Because of chronic pulmonary infections, the majority...... of diabetic retinopathy was found in patients with insulin-treated CF-related diabetes, stressing the need for a regular screening program as in type 1 diabetes. Severely impaired kidney function was common in lung transplant patients, probably secondary to cyclosporine treatment....

  7. Cystic mesothelioma of the peritoneum.

    Datta, R V; Paty, P B


    A 48-year-old man presented with a 3-month history of weight loss and progressive right lower quadrant abdominal pain. His medical history was notable for appendectomy at age 17. Ultrasonography and computed tomography of the abdomen revealed a 12 cm multicystic mass in the right paracolic space. At laparotomy a large serous cyst was found arising from the lateral wall of the cecum, and four additional small cysts were found on the small bowel mesentery, greater omentum, liver capsule, and right hemi-diaphragm. Complete removal of the tumor was accomplished by right colectomy with extraperitoneal dissection of the large cyst and simple excision of the four smaller cysts. Final pathology with immunohistochemical staining confirmed cystic mesothelioma of the peritoneum. In this report we discuss the diagnostic workup and treatment of this rare disease.

  8. Osseous metaplasia and mature bone formation with extramedullary hematopoiesis in follicular adenoma of thyroid gland

    Harsh Mohan


    Full Text Available Follicular adenomas of the thyroid may be subjected to degenerative changes like hemorrhagic and cystic changes, fibrosis, and calcification. Mature bone formation is a rare phenomenon, but extramedullary hematopoiesis (EMH has also been rarely reported in thyroid gland. The combination of mature bone formation and EMH is rarer and has been reported, in a single case report, in a multinodular goitre. We describe a case of follicular adenoma with histologically proven osseous metaplasia and mature bone formation with EMH in a middle- aged woman, which, to our knowledge, is the first case in English language literature.

  9. Endometrioid Paraovarian Borderline Cystic Tumor in an Infant with Proteus Syndrome

    Liliana Vasquez


    Full Text Available Ovarian and paraovarian neoplasms are uncommon in children, mainly originating from germ cell tumors and, least frequently, epithelial tumors. There is an association between genital tract tumors and Proteus syndrome, a rare, sporadic, and progressive entity, characterized by a postnatal overgrowth in several tissues caused by a mosaic mutation in the AKT1 gene. We describe a 20-month-old asymptomatic infant with Proteus syndrome who developed an endometrioid paraovarian borderline cystic tumor. This is the youngest patient so far reported in the literature with this rare syndrome and an adnexal tumor of borderline malignancy. A total of nine patients have been described with female tract tumors and associated Proteus syndrome, which includes bilateral ovarian cystadenomas and other benign masses. A paraovarian neoplasm is extremely rare in children and could be considered a criterion for Proteus syndrome. Standardized staging and treatment of these tumors are not well established; however, most authors conclude that these neoplasms must be treated as their ovarian counterparts.

  10. Gastrointestinal manifestations in cystic fibrosis.

    Eggermont, E


    CFTR, or cystic fibrosis transmembrane conductance regulator, the gene product that is defective in cystic fibrosis, is present in the apical membrane of the epithelial cells from the stomach to the colon. In the foregut, the clinical manifestations are not directly related to the primary defect of the CFTR chloride channel. The most troublesome complaints and symptoms originate from the oesophagus as peptic oesophagitis or oesophageal varices. In the small intestinal wall, the clinical expression of CF depends largely on the decreased secretion of fluid and chloride ions, the increased permeability of the paracellular space between adjacent enterocytes and the sticky mucous cover over the enterocytes. As a rule, the brush border enzyme activities are normal and there is some enhanced active transport as shown for glucose and alanine. The results of continuous enteral feeding of CF patients clearly show that the small intestinal mucosa, in the daily situation, is not functioning at maximal capacity. Although CFTR expression in the colon is lower, the large intestine may be the site of several serious complications such as rectal prolapse, meconium ileus equivalent, intussusception, volvulus and silent appendicitis. In recent years colonic strictures, after the use of high-dose pancreatic enzymes, are being increasingly reported; the condition has recently been called CF fibrosing colonopathy. The CF gastrointestinal content itself differs mainly from the normal condition by the lower acidity in the foregut and the accretion of mucins and proteins, eventually resulting in intestinal obstruction, in the ileum and colon. Better understanding of the CF gastrointestinal phenotype may contribute to improvement of the overall wellbeing of these patients.

  11. Audit Maturity Model

    Bhattacharya Uttam


    Full Text Available Today it is crucial for organizations to pay even greater attention on quality management as the importance of this function in achieving ultimate business objectives is increasingly becoming clearer. Importance of the Quality Management (QM Function in achieving basic need by ensuring compliance with Capability Maturity Model Integrated (CMMI / International Organization for Standardization (ISO is a basic demand from business nowadays. However, QM Function and its processes need to be made much more mature to prevent delivery outages and to achieve business excellence through their review and auditing capability. Many organizations now face challenges in determining the maturity of the QM group along with the service offered by them and the right way to elevate the maturity of the same. The objective of this whitepaper is to propose a new model –the Audit Maturity Model (AMM which will provide organizations with a measure of their maturity in quality management in the perspective of auditing, along with recommendations for preventing delivery outage, and identifying risk to achieve business excellence. This will enable organizations to assess QM maturity higher than basic hygiene and will also help them to identify gaps and to take corrective actions for achieving higher maturity levels. Hence the objective is to envisage a new auditing model as a part of organisation quality management function which can be a guide for them to achieve higher level of maturity and ultimately help to achieve delivery and business excellence.

  14. Pathohistological changes in fetuses with cystic fibrosis

    Đolai Matilda


    Full Text Available Introduction. Cystic fibrosis or mucoviscidosis is a genetically caused disease. The intensity of disease and histopathological changes grow throughout the life. According to the literature, pathological changes characteristic of cystic fibrosis become noticeable around the sixth month of life. Case Report. After amniocentesis of a 5-lunar month-old fetus had been done, which confirmed cystic fibrosis, the Ethics Commission approved the preterm labor. The autopsy and histopathological analysis demonstrated the existence of typical histopathological changes in the pancreas and intestines. Discussion. In the late fetal period or during the period around the delivery, cystic fibrosis is usually manifested as meconial cap with or without obstruction of the intestinal lumen. Morphological changes in the exocrine glands usually develop only after birth. In this case, the existence of meconial obstruction, as well as the typical acidofil content in the secretory ducts and acini of the pancreas was confirmed, which is unusual for the fetal age of five months.

  15. Epidural Cystic Spinal Meningioma: A Case Report.

    Zhang, Ji; Chen, Zheng-he; Wang, Zi-feng; Sun, Peng; Jin, Jie-tian; Zhang, Xiang-heng; Zhao, Yi-ying; Wang, Jian; Mou, Yong-gao; Chen, Zhong-ping


    Cystic spinal meningioma (CSM) is an uncommon meningioma variant. Extradural CSMs are particularly rare and difficult to distinguish from other intraaxial tumors. This study presents a case of a 36-year-old woman with intraspinal extradual CSM at the thoracolumbar spine. She experienced persistent weakness, progressive numbness, and sensory disturbance in the right lower limb. Magnetic resonance imaging (MRI) of the patient revealed an irregular cystic mass at the thoracic 11 to lumbar 3 levels dorsally. This case was misdiagnosed as other neoplasms prior to surgery because of the atypical radiographic features and location of the tumor. Extradural CSMs should be considered in the differential diagnosis of intraspinal extradural cystic neoplasms. Complete removal of cystic wall provides an optimal outcome, rendering the lesion curable.

  18. Radiological description of cystic pancreatic tumors.

    Rodríguez Torres, C; Larrosa López, R


    Although most cystic pancreatic lesions are pseudocysts, it is important to do a thorough differential diagnosis with true cystic tumors because cystic tumors are potentially malignant. Sometimes computed tomography and magnetic resonance imaging cannot establish the definitive diagnosis, making it necessary to perform other imaging tests such as endoscopic ultrasound, which in addition to morphological information, can also enable cytologic and biochemical analysis of the lesion through puncture and aspiration of its contents. Combining all these findings nearly always provides enough diagnostic information to allow the appropriate approach in each case. This article describes the specific morphological characteristics for each cystic pancreatic tumor on computed tomography, magnetic resonance imaging, and endoscopic ultrasound and reviews the guidelines for managing these types of lesions.

  1. Asymptomatic peritoneal carcinomatosis originating from benign cystic peritoneal mesothelioma.

    Iacoponi, S; Calleja, J; Hernandez, G; de la Cuesta, R Sainz


    Benign multicystic mesothelioma is a rare tumour that originates from the abdominal peritoneum with a predisposition to the pelvic peritoneum. It typically affects women of reproductive age. There have been less than 200 cases of this rare neoplasia reported to date. We present the case of a 35-year-old woman who was referred to our centre because of the detection of a peritoneal carcinomatosis during a gynaecological exam. A diagnostic laparoscopy was performed. The findings included multiple cysts appearing as 'a bunch of grapes' occupying the omentum. Biopsies were taken during the surgery and the results showed benign multicystic peritoneal mesothelioma. Benign multicystic mesothelioma can simulate other conditions, such as malignant ovarian tumours or cystic lymphangioma. It is often diagnosed accidentally during surgery performed for another reason. The diagnosis is interoperative, observing multicystic structures grouped as a 'bunch of grapes' containing clear fluid with thin walls made of connective tissue. Immunohistochemistry confirmed mesothelial origin. Surgery is considered the treatment of choice and is based on the removal of the cysts from the abdominal cavity. Hyperthermic intraperitoneal chemotherapy can be considered as a primary treatment in patients with recurrences or even as a part of primary treatment associated with surgery. Survival at 5 years is 100% and invasive or malignant progression is extraordinary. The treatment approach should be multidisciplinary, and the patient should be referred to a referral centre.

  2. Ovarian preservation in children for adenexal pathology, current trends in laparoscopic management and our experience

    Preet Agarwal


    Full Text Available Aims: Primary cysts and tumors of the ovary alongwith torsion are often regarded as an indication for open oophorectomy because of the fear of leaving an ischemic organ inside and chances of recurrence. We wish to report our experience of both modalities of management where we initially removed adenexal torsion by either laparoscopic salpingo-oophorectomy or oophorectomy, but later followed a more conservative approach of adenexal lesion removal with ovarian preservation. Materials and Methods: Retrospective review of clinical records of patients with ovarian pathology who were managed laparoscopically. Results: 46 cases of pediatric ovarian pathology were managed between March 2006 and March 2013 in two centers by a team of surgeons. The age ranged from 1 days to 18 years (average 14.3 years and the pathology varied from 30 cases of a simple ovarian cyst with torsion, 3 cases of ovarian torsion without any cyst, 7 cases of a dermoid cyst with torsion in all, 1 case of secreting ovarian tumor and 5 cases of a paraovarian cyst with torsion. All patients had a normal tumor marker except 1 girl with a functional ovarian tumor who had elevated LDH and estrogen levels alongwith suppressed LH and FSH. In the initial period of our study we did 1 salpingo-oophorectomy for a suspected complex lesion and two oophorectomies for torsion with a simple cyst. In the later part of our study we performed laparoscopic cystectomy and ovarian preservation in 40 cases, including 7 cases of dermoid, where we performed laparoscopic detorsion with dermoid cystectomy and ovarian preservation in the same sitting. In three cases of chronic torsion who presented to us late, we could not preserve the ovary and had to resort to salpingo-ophorectomy. Histology showed a simple corpus luteal and follicular ovarian cyst in 31 cases, a paraovarian cyst in 5 cases with mature teratoma in 7 cases.

    Rosenberg, Mark F.; O'Ryan, Liam P.; Hughes, Guy; Zhao, Zhefeng; Aleksandrov, Luba A.; Riordan, John R.; Ford, Robert C.


    Cystic fibrosis affects about 1 in 2500 live births and involves loss of transmembrane chloride flux due to a lack of a membrane protein channel termed the cystic fibrosis transmembrane conductance regulator (CFTR). We have studied CFTR structure by electron crystallography. The data were compared with existing structures of other ATP-binding cassette transporters. The protein was crystallized in the outward facing state and resembled the well characterized Sav1866 transporter. We identified ...

    Varsha Manucha


    Full Text Available We present a case of a cystic adenomatoid tumor in a 40-year-old woman. The tumor was an intramural multicystic mass, histologically similar to a multicystic mesothelioma. Cystic adenomatoid tumors of the uterus are extremely rare. They present with a wide differential diagnosis in radiology. The tumors are known to be benign and awareness of this rare entity is the key to its diagnosis for a pathologist.

    Neuropilin-1 (Nrp1) guides the development of the nervous and vascular systems, but its role in the mature brain remains to be explored. Here we report that the expression of the 65 kDa isoform of Sema3A, the ligand of Nrp1, by adult vascular endothelial cells, is regulated during the ovarian cycle

  7. Issues for mature women with epilepsy.

    Harden, Cynthia L


    Specific concerns regarding mature women with epilepsy (WWE), specifically epilepsy-associated issues during perimenopause, menopause, and postmenopause, have been emerging in the epilepsy community. This chapter presents evidence that for WWE, seizure frequency may increase during perimenopause and decrease at postmenopause, especially if a catamenial epilepsy pattern was present during the reproductive years. This finding implies that, as in other age groups, a subset of mature WWE are particularly susceptible to endogenous reproductive hormonal changes. An adverse effect on seizure frequency with the use of hormone replacement therapy (HRT) during postmenopause for WWE was reported in surveys, and a dose-related association between standard HRT and increased seizures was later borne out in a double-blind, placebo-controlled, randomized clinical trial. Management of symptomatic postmenopausal WWE using estrogenic and progestogenic compounds that are less likely to promote seizures is discussed. WWE are at risk for premature ovarian failure and for menopause at a younger age than the general population. This appears to be related to epilepsy severity in terms of seizure frequency and is likely a consequence of adverse effects of seizures and interictal activity on the hypothalamo-pituitary-gonadal axis. The decline in antiepileptic drug (AED) clearance, as well as alterations in gastric functioning and decreasing albumin levels, with maturity can affect AED use in the aging population; therefore, mature individuals with epilepsy need to be monitored carefully for toxicity and for increasing AED levels that could eventually cause toxicity. Information about gender differences for AED use in the mature population is scant.

  8. Gorlin syndrome presenting with a unilateral ovarian fibroma in a 22-year-old woman: a case report

    Finch Terence


    Full Text Available Abstract Introduction Nevoid basal cell carcinoma syndrome, or Gorlin syndrome, is an inherited disorder characterized by malignancies of the skin and other organs, skeletal abnormalities, and congenital malformations. The syndrome follows an autosomal dominant inheritance pattern with a gene mutation localized to 9q22.3. Case presentation We present the case of a 22-year-old Caucasian woman with a unilateral ovarian fibroma, falx cerebri calcification and odontogenic keratocysts, but without any skin manifestations. The diagnosis of nevoid basal cell carcinoma syndrome was made after a right salpingo-oophorectomy for a calcified ovarian fibroma with cystic degeneration. Pathologic examination of the 10 cm right ovarian mass revealed a well-circumscribed spindle cell lesion. Immunohistochemical staining of the lesion demonstrated positivity for vimentin and smooth muscle actin. Conclusion It is important to recognize that nevoid basal cell carcinoma syndrome may present in the absence of skin lesions. Additionally, ovarian fibromas are typically bilateral in nevoid basal cell carcinoma syndrome, but can uncommonly be unilateral, which may alter clinical management. Ovarian fibromas are managed with surgical excision with an attempt at ovarian functional preservation.

  9. Microfocus of Anaplastic Carcinoma Arising in Mural Nodule of Ovarian Mucinous Borderline Tumor With Very Rapid and Fatal Outcome.

    Mhawech-Fauceglia, Paulette; Ramzan, Amin; Walia, Saloni; Pham, Huyen Q; Yessaian, Annie


    A 36-yr-old woman presented with abdominal discomfort. A computed tomography scan revealed a large left cystic and solid pelvic mass without evidence of metastatic disease. Total hysterectomy with bilateral salpingo-oophorectomy and tumor staging was performed. Grossly, the ovarian mass measured 20×18 cm and the cut surface was multiloculated with 1 single mural nodule measuring 2×1.5 cm. The histologic diagnosis of ovarian mucinous borderline tumor with a microfocus of anaplastic carcinoma arising in sarcoma-like mural nodule, FIGO Stage IA was rendered. After 3 mo, the patient returned with symptomatic anemia. A computed tomography scan showed enlarged retroperitoneal and pelvic lymph nodes. Image-guided biopsy of the pelvic lymph node showed a metastatic anaplastic carcinoma from her primary ovarian carcinoma. Chemotherapy was initiated, but the patient developed fulminant disseminated intravascular coagulation within <1 wk of her presentation which was fatal.

  10. Ovarian Fibrosis: A Phenomenon of Concern

    Zhou, Feng; Shi, Li-Bing; Zhang, Song-Ying


    Objective: Ovarian fibrosis is characterized by excessive proliferation of ovarian fibroblasts and deposition of extracellular matrix (ECM) and it is one of the principal reasons for ovarian dysfunction. This review aimed to investigate the pathogenetic mechanism of ovarian fibrosis and to clarify the relationship between ovarian diseases and fibrosis. Data Sources: We searched PubMed for English language articles published up to November 2016. The search terms included ovarian fibrosis OR fibrosis, ovarian chocolate cyst OR ovarian endometrioma, polycystic ovarian syndrome (PCOS), premature ovarian failure, ECM, matrix metalloproteinases (MMPs), tissue inhibitors of matrix metalloproteinases (TIMPs), transforming growth factor-beta 1 (TGF-β1), connective tissue growth factor (CTGF), peroxisome proliferator-activated receptor gamma (PPAR-γ), vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), and combinations of these terms. Study Selection: Articles were obtained and reviewed to analyze the pathogenic mechanism of ovarian fibrosis and related ovarian diseases. Results: Many cytokines, such as MMPs, TIMPs, TGF-β1, CTGF, PPAR-γ, VEGF, and ET-1, are involved in ovarian fibrogenesis. Ovarian fibrogenesis is associated with various ovarian diseases, including ovarian chocolate cyst, PCOS, and premature ovarian failure. One finding of particular interest is that fibrogenesis in peripheral tissues around an ovarian chocolate cyst commonly causes ovarian function diminution, and therefore, this medical problem should arouse widespread concern in clinicians worldwide. Conclusions: Patients with ovarian fibrosis are susceptible to infertility and tend to have decreased responses to assisted fertility treatment. Thus, protection of ovarian function should be a priority for women who wish to reproduce when making therapeutic decisions about ovarian fibrosis-related diseases. PMID:28139522

  11. Ovarian Teratoma Masquerading as a CSF Pseudocyst in a Female with a Ventriculoperitoneal Shunt

    John M. K. Mislow


    Full Text Available Background. In today's fast-paced and high-acuity emergency departments, clinicians are often compelled to triage cases so rapidly that a differential diagnosis consistent with the history and physical examination is not comprehensive. Case Report. This case report describes the unexpected finding of a cystic ovarian neoplasm in a young female with an abdominal mass and a ventriculoperitoneal shunt, initially diagnosed as a cerebrospinal fluid pseudocyst. We use this case to illustrate that the astute clinician must always synthesize a diagnosis from all data sources and not to rely on initial radiographic evaluations. Conclusions. This remarkable case demonstrates that all differential diagnoses must be entertained in order to rapidly and accurately diagnose a patient with a cystic abdominal mass.

  12. Successful Vaginal Delivery despite a Huge Ovarian Mucinous Cystadenoma Complicating Pregnancy: A Case Report

    Dipak Mandi


    Full Text Available A 22-year-old patient with 9 months of amenorrhea and a huge abdominal swelling was admitted to our institution with an ultrasonography report of a multiloculated cystic space-occupying lesion, almost taking up the whole abdomen (probably of ovarian origin, along with a single live intrauterine fetus. She delivered vaginally a boy baby within 4 hours of admission without any maternal complication, but the baby had features of intrauterine growth restriction along with low birth weight. On the 8th postpartum day, the multiloculated cystic mass, which arose from the right ovary and weighed about 11 kg, was removed via laparotomy. A mucinous cystadenoma with no malignant cells in peritoneal washing was detected in histopathology examination. This report describes a rare case of a successful vaginal delivery despite a huge cystadenoma of the right ovary complicating the pregnancy.

  13. The Effects of Progesterone on Oocyte Maturation and Embryo Development

    Saeed Zavareh


    Full Text Available Oocyte maturation and embryo development are controlled by intra-ovarian factors suchas steroid hormones. Progesterone (P4 exists in the follicular fluid that contributes tonormal mammalian ovarian function and has several critical functions during embryodevelopment and implantation, including endometrial receptivity, embryonic survivalduring gestation and transformation of the endometrial stromal cells to decidual cells.It is well known that the physiological effects of P4 during the pre-implantation stages ofsome mammal’s embryos are mediated by P4 receptors and their gene expression is determined.The effects of P4 on oocytes and embryo development have been assessed bysome investigations, with contradictory results. P4, a dominant steroid in follicular fluidat approximately 18 hours after the luteinizing hormone (LH surge may have a criticalrole in maturation of oocytes at the germinal stage. However, it has been shown that differentconcentrations of P4 could not improve in vitro maturation rates of germinal vesicles(GV in cumulus oocyte complexes (COCs and cumulus denuded oocytes (CDOs.Culture media supplemented with P4 significantly improved mouse embryo development.In addition, an in vivo experimental design has shown high blastocyst survival andimplantation rates in P4-treated mice.In this review we explain some of the findings that pertain to the effects of P4 onoocyte maturation and embryo development both in vitro and in vivo.

  14. Non-coding RNAs in the Ovarian Follicle

    Rosalia Battaglia


    Full Text Available The mammalian ovarian follicle is the complex reproductive unit comprising germ cell, somatic cells (Cumulus and Granulosa cells, and follicular fluid (FF: paracrine communication among the different cell types through FF ensures the development of a mature oocyte ready for fertilization. This paper is focused on non-coding RNAs in ovarian follicles and their predicted role in the pathways involved in oocyte growth and maturation. We determined the expression profiles of microRNAs in human oocytes and FF by high-throughput analysis and identified 267 microRNAs in FF and 176 in oocytes. Most of these were FF microRNAs, while 9 were oocyte specific. By bioinformatic analysis, independently performed on FF and oocyte microRNAs, we identified the most significant Biological Processes and the pathways regulated by their validated targets. We found many pathways shared between the two compartments and some specific for oocyte microRNAs. Moreover, we found 41 long non-coding RNAs able to interact with oocyte microRNAs and potentially involved in the regulation of folliculogenesis. These data are important in basic reproductive research and could also be useful for clinical applications. In fact, the characterization of non-coding RNAs in ovarian follicles could improve reproductive disease diagnosis, provide biomarkers of oocyte quality in Assisted Reproductive Treatment, and allow the development of therapies for infertility disorders.

  15. Targeted Correction and Restored Function of the CFTR Gene in Cystic Fibrosis Induced Pluripotent Stem Cells

    Ana M. Crane


    Full Text Available Recently developed reprogramming and genome editing technologies make possible the derivation of corrected patient-specific pluripotent stem cell sources—potentially useful for the development of new therapeutic approaches. Starting with skin fibroblasts from patients diagnosed with cystic fibrosis, we derived and characterized induced pluripotent stem cell (iPSC lines. We then utilized zinc-finger nucleases (ZFNs, designed to target the endogenous CFTR gene, to mediate correction of the inherited genetic mutation in these patient-derived lines via homology-directed repair (HDR. We observed an exquisitely sensitive, homology-dependent preference for targeting one CFTR allele versus the other. The corrected cystic fibrosis iPSCs, when induced to differentiate in vitro, expressed the corrected CFTR gene; importantly, CFTR correction resulted in restored expression of the mature CFTR glycoprotein and restoration of CFTR chloride channel function in iPSC-derived epithelial cells.

  18. Ovarian Surface Epithelium in Patients with Severe Ovarian Infertility: A Potential Source of Cells Expressing Markers of Pluripotent/Multipotent Stem Cells

    Irma Virant-Klun


    Full Text Available The aim of this study was to confirm the presence of stem cells in the ovarian surface epithelium of patients with premature ovarian failure and no mature follicles and oocytes. In these patients, small round cells of unknown origin expressing SOX-2 marker of pluripotency were observed among the epithelial cells just after the ovarian surface epithelium scraping. These cells were an integral part of the ovarian surface epithelium. When the scraped cells were cultured in a medium with added follicular fluid to provide some ovarian niche, primitive oocyte-like cells and typical round-shaped cell clusters positively stained on alkaline phosphatase, and markers of pluripotency, such as SOX-2 and SSEA-4, were developed. These markers were expressed early and also later in the culture. Single oocyte-like cells expressed genes OCT4A, SOX-2, NANOG, NANOS, STELLA, CD9, LIN28, KLF4, GDF3, and MYC, characteristic for pluripotent stem cells. The results of this study confirmed the presence of putative stem cells in the ovarian surface epithelium of these patients and provided some basis to create a stem cell line in the future.

    Ye Bi-lu; Zhao Jun-zhao; Wang Pei-yt


    Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility.If PCOS infertile women fail to conceive after conventional induction of ovulation,the assisted reproductive therapy is an alternative method for pregnancy.In-vitro maturation is an efficient,more economical and simple method without ovarian hyperstimulation syndrome complication.

  2. Live Birth from ICSI-TESA into In Vitro Matured Oocytes: A Case Report.

    Hatırnaz, Şafak; Hatırnaz, Ebru; Bakacak, Murat; Bostancı, Mehmet Sühha; Atasever, Melahat


    Repeated in vitro Fertilization (IVF) failure together with Ovarian Hyperstimulation Syndrome (OHSS) is one of the distressing situations leading couples to search for alternative treatment options. For such patients with Polycystic Ovarian Syndrome (PCOS) who have experienced Ovarian Hyperstimulation Syndrome, mild ovarian stimulation with in vitro oocyte maturation could be a promising alternative. Testicular Sperm Aspiration (TESA) of spermatozoa from a known obstructive azoospermic patient is a limiting factor for IVM (in vitro maturation) but the couple reported here accepted mild IVF -IVM with TESA. In the treatment of a 32-year old woman, 9 immature oocytes were retrieved, 5 in vitro matured oocytes (maturation rate 55%) and after fertilization by Intracytoplasmic Sperm Injection (ICSI), 3 oocytes (fertilization rate 60%) which had two pronuclei and two good quality embryos on day 2, were transferred. A live pregnancy was observed by ultrasound scan and healthy infant was delivered. Although the number of births from ICSI of immature oocytes injected with surgically derived sperm is quite low, the selection of this mode of therapy as an alternative to conventional IVF will overcome the limitations and provides a new option in IVF practice.

  5. Renal cystic disease proteins play critical roles in the organization of the olfactory epithelium.

    Jennifer L Pluznick

    Full Text Available It was reported that some proteins known to cause renal cystic disease (NPHP6; BBS1, and BBS4 also localize to the olfactory epithelium (OE, and that mutations in these proteins can cause anosmia in addition to renal cystic disease. We demonstrate here that a number of other proteins associated with renal cystic diseases - polycystin 1 and 2 (PC1, PC2, and Meckel-Gruber syndrome 1 and 3 (MKS1, MKS3 - localize to the murine OE. PC1, PC2, MKS1 and MKS3 are all detected in the OE by RT-PCR. We find that MKS3 localizes specifically to dendritic knobs of olfactory sensory neurons (OSNs, while PC1 localizes to both dendritic knobs and cilia of mature OSNs. In mice carrying mutations in MKS1, the expression of the olfactory adenylate cyclase (AC3 is substantially reduced. Moreover, in rats with renal cystic disease caused by a mutation in MKS3, the laminar organization of the OE is perturbed and there is a reduced expression of components of the odor transduction cascade (G(olf, AC3 and α-acetylated tubulin. Furthermore, we show with electron microscopy that cilia in MKS3 mutant animals do not manifest the proper microtubule architecture. Both MKS1 and MKS3 mutant animals show no obvious alterations in odor receptor expression. These data show that multiple renal cystic proteins localize to the OE, where we speculate that they work together to regulate aspects of the development, maintenance or physiological activities of cilia.

  6. Surgical outcome in cystic vestibular schwannomas

    Nair, Suresh; Baldawa, Sachin S.; Gopalakrishnan, Chittur Viswanathan; Menon, Girish; Vikas, Vazhayil; Sudhir, Jayanand B.


    Background: Cystic vestibular schwannomas (VS) form a rare subgroup that differs from the solid variant clinically, radiologically, and histopathologically. These tumors also vary in their surgical outcome and carry a different risk of post-operative complications. We analyzed our series of 64 patients with cystic VS and discuss the technical difficulties related to total excision of these tumors and focus on complication avoidance. Materials and Methods: A retrospective review of cystic VS surgically managed over a span of 11 years. The case records were evaluated to record the clinical symptoms and signs, imaging findings, surgical procedure, complications, and follow-up data. Post-operative facial nerve palsy was analyzed with respect to tumor size and tumor type. Results: Progressive hearing impairment was the most common initial symptom (76.6%). Atypical initial symptoms were present in 15 patients (23.4%). Preoperatively, 78% patients had good facial nerve function (HB grade 1, 2) and 22% had intermediate (HB grade 3, 4) to poor (HB grade 5 and 6) function. Mean tumor size was 4.1 cm. Complete tumor removal was achieved in 53 patients (83%). The facial nerve was anatomically intact but thinned out after tumor excision in 38 patients (59.4%). Ninety percent patients had either intermediate or poor facial nerve function at follow-up. Poor facial nerve outcome was associated with giant tumors and peripherally located, thin-walled cystic tumors. Conclusion: Resection of cystic VS is complicated by peritumoral adhesions of the capsule to the nerve. Extensive manipulation of the nerve in order to dissect the tumor–nerve barrier results in worse facial nerve outcome. The outcome is worse in peripherally located, thin-walled cystic VS as compared to centrally located, thick-walled cystic tumors. Subtotal excision may be justified, especially in tumors with dense adhesion of the cyst wall to the facial nerve in order to preserve nerve integrity. PMID:27366248

  7. Subtypes of Ovarian Cancer and Ovarian Cancer Screening

    Koshiyama, Masafumi; Matsumura, Noriomi; Konishi, Ikuo


    Ovarian cancer is the foremost cause of gynecological cancer death in the developed world, as it is usually diagnosed at an advanced stage. In this paper we discuss current issues, the efficacy and problems associated with ovarian cancer screening, and compare the characteristics of ovarian cancer subtypes. There are two types of ovarian cancer: Type I carcinomas, which are slow-growing, indolent neoplasms thought to arise from a precursor lesion, which are relatively common in Asia; and Type II carcinomas, which are clinically aggressive neoplasms that can develop de novo from serous tubal intraepithelial carcinomas (STIC) and/or ovarian surface epithelium and are common in Europe and the USA. One of the most famous studies on the subject reported that annual screening using CA125/transvaginal sonography (TVS) did not reduce the ovarian cancer mortality rate in the USA. In contrast, a recent study in the UK showed an overall average mortality reduction of 20% in the screening group. Another two studies further reported that the screening was associated with decreased stage at detection. Theoretically, annual screening using CA125/TVS could easily detect precursor lesions and could be more effective in Asia than in Europe and the USA. The detection of Type II ovarian carcinoma at an early stage remains an unresolved issue. The resolving power of CA125 or TVS screening alone is unlikely to be successful at resolving STICs. Biomarkers for the early detection of Type II carcinomas such as STICs need to be developed. PMID:28257098

  8. Effect of Previous Chemotherapy on the Quality of Cryopreserved Human Ovarian Tissue In Vitro.

    Babak Asadi Azarbaijani

    Full Text Available Cryopreservation of ovarian tissue has been widely accepted as an option for fertility preservation among cancer patients. Some patients are exposed to chemotherapy prior to ovarian tissue cryopreservation. Consequently, assessment of the developmental capacity of human ovarian tissue after chemotherapy is of primary importance.In order to study the impact of previous chemotherapy on in vitro development and viability of ovarian follicles, quality control samples from 34 female cancer patients at median age of 15 years (range 1‒35, cryopreserved for fertility preservation before (n = 14 or after (n = 20 initiation of chemotherapy, were thawed and cultured for 7 days. The morphology and developmental stages of ovarian follicles were studied by light microscopy before and after culture. Possible associations between follicular densities, age and exposure to alkylating agents, expressed as cyclophosphamide equivalent dose (CED were tested.Exposure to chemotherapy significantly impaired the survival and development of ovarian follicles in culture. After seven days, significantly higher densities of intermediary, primary and secondary follicles and lower densities of atretic follicles was detected in the samples collected before chemotherapy. Increasing dose of alkylating agents was identified by multivariate linear regression analysis as an independent predictor of a higher density of atretic follicles, whereas increasing age of the patient predicted a better outcome with less follicle atresia and a higher density of maturing follicles.This study provides quantitative in vitro evidence of the impact of chemotherapy on developmental capacity of cryopreserved human ovarian tissue. The results indicate that fertility preservation should be carried out, if possible, before initiation of alkylating agents in order to guarantee better in vitro survival of ovarian follicles. In addition, ovarian samples from younger girls show lower viability and fewer

    Full Text Available The use of PGF2 α is based on its luteolytic effect causing regression of corpus luteum and allows development of dominant follicle on the ovary that result in estrus and ovulation in 72 to 96 hours after its administration. Moreover, the PGF2 α also causes relaxation of cervix and smooth muscle contractions of uterus. The use of PGF2 α may provide microbial resistance in uterine environment, on one hand and can favour and enhance body defense mechanism / phagocytic activity on the other hand. PGF2 α is widely used to get rid of from the conditions like luteal cystic ovarian disease, persistent corpus luteum, endometritis, abnormal pregnancy, pyometra, retention of placenta and mummification. It has been now in vogue to administer PGF2 α or its analogue in early postpartum cows and buffaloes in order to hasten early resumption of cyclic ovarian activity and thereby to increase the reproductive efficiency.

  11. Mucinous Cystic Adenoma of Ovary in a 15-Year-Old Girl with an Unusual Presentation (A Case Report

    Allahbakhsh Rahimi


    Full Text Available Introduction: Ovarian cysts are relatively rare in children. Mucinous cystadenomas are rarely encountered in adolescent patients and can reach an enormous size. Mural nodules associated with mucinous tumors of the ovary may represent a benign or malignant process."nCase Presentation: Our case was a 15-year-old female, which referred with a painless abdominal distention gradually appearing during six months. There was no specific symptom only mild discomfort of bowel habits with the regular menstruation. On physical examination, there was complete distention of the abdomen without any tenderness. Ultrasonography revealed a large loculated cystic mass in the abdominopelvic cavity, which contained few septations and mural nodules without any vascularity on color Doppler ultrasonography. All other organs appeared normal. On contrast enhanced CT scan, there was a large intra-peritoneal 280×250×170 mm anteriorly located cystic mass which extended from the upper abdomen down to the lower pelvis displacing and compressing adjacent structures posterolaterally. Multiple enhancing septa and two mural nodules were found in the cystic mass. All solid organs appeared normal and no significant adenopathy or ascitis was detected. According to the above findings, omental cysts, adenexal cysts, urachal cysts, mesenteric cysts were our differential diagnosis. A 10 kg mass was resected (an exophytic cyst in the right ovary and histopathology revealed mucinous cystic adenoma of the right ovary with fibrotic mural nodules. No recurrence was detected after one year."nDiscussion: Mucinous cystadenomas are rarely encountered in adolescent patients and can reach an enormous size. The interesting point of this case was not only because of its rarity but also because of its unusual symptomless manifestation and also fibrotic mural nodules."nKeywords: Mucinous Cystic Adenoma, Ovary, Adolescence

    Ute Katharina Bartels


    Full Text Available AbstractIntroduction: Craniopharyngioma of childhood are commonly cystic in nature. An intracystic catheter insertion and subsequent instillation of substances inducing cyst shrinkage seems a beneficial strategy avoiding additional morbidity in a highly vulnerable brain location. Methods: A systematic review of the medical literature was performed to identify potentially relevant, all languages articles using Ovid MEDLINE and EMBASE from inception to July 2011 and Cochrane Central Register of Controlled Trials to 3rd quarter 2011. All references were examined for relevancy. Results: Of 142 unique references x referred to substances used for intracystic craniopharyngioma treatment. General aspects of intracystic catheter insertion as well as response rates, risks and outcomes of children treated with intracystic radio-isotopes, bleomycin and interferon are critically reviewed and an outline for potential future endeavours provided. Conclusions: Interferon seems currently the intracystic substance with the best benefit risk ratio. The authors advocate for consensus on prospective data collection and standardized intracystic treatment strategies to allow reliable comparisons and herewith optimize treatment and outcome.

  13. Cystic fibrosis: a clinical view.

    Castellani, Carlo; Assael, Baroukh M


    Cystic fibrosis (CF), a monogenic disease caused by mutations in the CFTR gene on chromosome 7, is complex and greatly variable in clinical expression. Airways, pancreas, male genital system, intestine, liver, bone, and kidney are involved. The lack of CFTR or its impaired function causes fat malabsorption and chronic pulmonary infections leading to bronchiectasis and progressive lung damage. Previously considered lethal in infancy and childhood, CF has now attained median survivals of 50 years of age, mainly thanks to the early diagnosis through neonatal screening, recognition of mild forms, and an aggressive therapeutic attitude. Classical treatment includes pancreatic enzyme replacement, respiratory physiotherapy, mucolitics, and aggressive antibiotic therapy. A significant proportion of patients with severe symptoms still requires lung or, less frequently, liver transplantation. The great number of mutations and their diverse effects on the CFTR protein account only partially for CF clinical variability, and modifier genes have a role in modulating the clinical expression of the disease. Despite the increasing understanding of CFTR functioning, several aspects of CF need still to be clarified, e.g., the worse outcome in females, the risk of malignancies, the pathophysiology, and best treatment of comorbidities, such as CF-related diabetes or CF-related bone disorder. Research is focusing on new drugs restoring CFTR function, some already available and with good clinical impact, others showing promising preliminary results that need to be confirmed in phase III clinical trials.

  14. Male fertility in cystic fibrosis.

    Chotirmall, S H


    Infertility rates among males with cystic fibrosis (CF) approximate 97%. No information is currently available within Ireland determining an understanding of fertility issues and the best methods of information provision to this specialized group. This study aimed to determine understanding and preferred approaches to information provision on fertility issues to Irish CF males. A Descriptive Study utilizing prospective coded questionnaires was mailed to a male CF cohort (n=50). Sections included demographics, fertility knowledge & investigation. Response rate was 16\\/50 (32%). All were aware that CF affected their fertility. More than two-thirds (n=11) were able to provide explanations whilst only one-third (n=5) provided the correct explanation. Significant numbers stated thoughts of marriage and a future family. Half have discussed fertility with a healthcare professional (HCP). Mean age of discussion was 21.9 years. One third preferred an earlier discussion. The commonest first source for information was written material which was also the preferred source. Three-quarters requested further information preferring again, written material. Significant gaps in sex education of Irish CF males exist. Discussion should be initiated by HCPs and centre-directed written material devised to address deficiencies.

  15. A comparison of adrenal gland function in lactating dairy cows with or without ovarian follicular cysts.

    Silvia, William J; McGinnis, Angela S; Hatler, T Ben


    Two experiments were conducted to determine if adrenal secretion of steroids differed between cows that formed ovarian follicular cysts and normal cycling cows. In experiment 1, lactating Jersey and Holstein cows were diagnosed as having ovarian follicular cysts (follicle diameter >or=20 mm) by rectal palpation. Following diagnosis, ovaries were examined by transrectal ultrasonography three times weekly to detect subsequent ovulation (n=8) or new cyst formation (n=9). Venous blood samples were collected daily to quantify circulating concentrations of cortisol and progesterone. The average concentration of cortisol during the 10-day period prior to ovulation was not different from the concentration prior to the formation of a new cyst. In experiment 2, secretion of cortisol and progesterone was examined in cows with ovarian follicular cysts (n=4) and cyclic, control cows in the follicular phase of the estrous cycle (n=4). An adrenocorticotropic hormone (ACTH) challenge was administered to cystic cows 4-7 days after new cyst formation and to cyclic cows in the follicular phase of the cycle (36 h after induction of luteolysis). Jugular venous blood samples were collected at -60, -30, 0, +10, +20, +30, +60, +90, +120, +180, +240, +300 and +360 minutes relative to ACTH administration. A rapid increase in both cortisol and progesterone was observed immediately following administration of ACTH in each treatment group. Peak concentrations of both steroids were achieved within 60 minutes after administration of ACTH. Concentrations of cortisol and progesterone did not differ between cystic and cyclic cows. In summary, no differences in adrenal function were detected between normal cycling cows and cows with ovarian follicular cysts.

  16. Ovarian cancer: the neglected diagnosis.

    Yawn, Barbara P; Barrette, Brigitte A; Wollan, Peter C


    To investigate presenting signs and symptoms of ovarian cancer and stage of tumor in a community cohort of women with the diagnosis of ovarian cancer. We reviewed retrospectively the medical records of all women who sought primary and specialty care in Olmsted County, Minnesota, between January 1, 1985, and December 31, 1997, to evaluate presenting symptoms, time from first symptom to diagnosis of ovarian cancer, and stage of tumor at diagnosis. Of 107 women with a diagnosis of ovarian cancer, the most commonly documented presenting symptom was crampy abdominal pain. Urinary symptoms and abdominal pain were the most commonly documented presenting symptom in patients with stage I and II ovarian cancers, whereas abdominal pain and increased abdominal girth were the most commonly documented symptoms in patients with stage III and IV cancer. Approximately 15% of tumors (n = 15) were found during routine evaluations or during a procedure for another problem. Less than 25% of presenting symptoms (n = 24 women) related directly to the pelvis or were more traditional gynecologic symptoms. Delays in women seeking medical care, health care system issues, competing medical conditions, physicians' failure to follow up, and women not returning for follow-up were associated with longer time to diagnosis. Both stage I and II cancer are associated with symptoms, but few symptoms are directly related to the reproductive pelvic organs or unique to ovarian cancer. A longer interval from first sign or symptom to diagnosis of ovarian cancer is associated with both patient and health care system factors.

  17. Decidualized Ovarian Mass Mimicking Malignancy

    Lufee Wong


    Full Text Available Deciduosis classically occurs in the context of known endometriosis in the pelvis, most commonly in the ovaries, but also in the peritoneum. However, ovarian deciduosis outside the context of endometriosis is rare and makes diagnosis difficult, especially as the sonographic appearance suggests a malignant process. We report a case of decidualized ovarian mass in a patient without prior history of endometriosis that mimicked an ovarian malignancy. MRI may be a useful imaging modality to monitor these lesions and guide management. Consultation with a multidisciplinary team accustomed to such conditions will help to tailor the management to each individual.

  5. Premalignant cystic neoplasms of the pancreas.

    Dudeja, Vikas; Allen, Peter J


    Due to increasing utilization of cross-sectional imaging, asymptomatic pancreatic cysts are frequently being diagnosed. Many of these cysts have premalignant potential and offer a unique opportunity for cancer prevention. Mucinous cystic neoplasm and intraductal papillary mucinous neoplasm are the major premalignant cystic neoplasms of pancreas. The prediction of the risk of malignancy (incidental and future risk of malignant transformation) and balancing the risks of watchful waiting with that of operative management with associated mortality and morbidity is the key to the management of these lesions. We review the literature that has contributed to the development of our approach to the management of these cystic neoplasms. We provide an overview of the key features used in diagnosis and in predicting malignancy. Particular attention is given to the natural history and management decision making.

  6. Histomorphological Evaluation of Fresh Ovarian Tissue Transplanted Into Back Muscles of Balb/C Mice

    I Amiri


    Full Text Available & objectives: Today, different methods for maintaining reproductive capability in young women with cancer are being considered. One of the most prominent of these methods is ovarian tissue transplant. Despite the relative success of this method, the appropriate location and methods of transplantation is still a matter of discussion. The present study evaluated the histomorphology of fresh ovarian tissue transplantation by two methods, inter muscular and intra muscular, in Balb/C mice. Methods & Materials: The study was conducted at Hamedan University of Medical Sciences in 2009. Fresh ovarian tissues from 12-14 day old Balb/C mice were transplanted into back muscles of ovarectomized 6 week old Balb/C mice both intermuscularly and intramuscularly. All transplanted mice received intra-peritoneal injections of a unit of rFSH for 4 weeks, every other day. At the end of the tenth week, all transplant recipient mice were killed and the transplanted ovarian tissues were removed. All samples were assessed for the angiogenesis and viability of follicles. Data were analyzed using SPSS software, using independent t- test. Results: In intermuscular transplanted group, the transplanted tissues were rejected in two cases. In the sections prepared from the other cases, in spite of the presence of some small necrotic areas, the majority of ovarian tissues had a healthy appearance within the primordial, primary, secondary and antral follicles. Apart from a significant reduction in the number of follicles and smaller size of follicles in the transplanted tissue in comparison with control group, no other major differences in morphology, histology, and the process of maturation of ovarian follicles were observed between the transplanted and control groups. Conclusion: Fresh ovarian tissue transplantation into muscles of the back area without basic vascular pedicle has new angiogenesis capabilities, appropriate survival and development of primordial follicles and

  7. Cystic echinococcosis in Southern Israel.

    Ben-Shimol, Shalom; Sagi, Orli; Houri, Ohad; Bazarsky, Elina; Berkowitz, Anat; Bulkowstein, Shlomi; Barrett, Chiya; Greenberg, David


    The aim of this retrospective, population-based study was to characterize demographically and clinically cystic-echinococcosis (CE) in southern Israel, between 2005 and 2012. Newly-diagnosed (nd-CE) and past-diagnosed (pd-CE, diagnosed before the study) cases were defined. Two populations live in southern-Israel, receiving medical treatment at a single hospital: the Jewish and the Bedouin populations (resembling resource-rich and resource-poor populations, respectively). 126 CE cases were identified; 55 nd-CE and 71 pd-CE. Mean annual nd-CE incidence per 100,000 in the Bedouin and Jewish populations were 2.7 ± 1.2 and 0.4 ± 0.3, respectively (Pborn outside Israel. Liver and lung involvement were recorded in 85.7% and 15.1% of overall-CE, respectively. Abdominal pain, cough, fever, eosinophilia and asymptomatic disease were documented in 63.6%, 32.7%, 27.3%, 41.5% and 12.7% of nd-CE, respectively. Serology sensitivity for first test and any positive test were 67.3% and 83.3%, respectively. Computed tomography, ultrasonography and X-ray diagnosis were documented in 79.2%, 58.4% and 17.0% of overall-CE, respectively, with ultrasonography mainly used in liver-CE and X-ray in lung-CE. Treatment included surgery and albendazole in 50.0% and 55.3% of CE, respectively. We conclude that CE is endemic in southern-Israel among the Bedouin population, while disease is probably mainly imported in the Jewish population. Liver involvement and eosinophilia rates were high compared with those of other endemic regions, possibly due to differences in the timing of diagnosis. These findings may help developing treatment and prevention strategies.

  8. Genetics of Cystic Fibrosis: Clinical Implications.

    Egan, Marie E


    Cystic fibrosis (CF) is a common life-shortening autosomal recessive genetic disorder caused by mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator protein (CFTR). Almost 2000 variants in the CFTR gene have been identified. The mutational classes are based on the functional consequences on CFTR. New therapies are being developed to target mutant CFTR and restore CFTR function. Understanding specific CF genotypes is essential for providing state-of-the art care to patients. In addition to the variation in CFTR genotype, there are several modifier genes that contribute to the respiratory phenotype.

  9. Diagnosis of Adult Patients with Cystic Fibrosis.

    Nick, Jerry A; Nichols, David P


    The diagnosis of cystic fibrosis (CF) is being made with increasing frequency in adults. Patients with CF diagnosed in adulthood typically present with respiratory complaints, and often have recurrent or chronic airway infection. At the time of initial presentation individuals may appear to have clinical manifestation limited to a single organ, but with subclinical involvement of the respiratory tract. Adult-diagnosed patients have a good response to CF center care, and newly available cystic fibrosis transmembrane receptor-modulating therapies are promising for the treatment of residual function mutation, thus increasing the importance of the diagnosis in adults with unexplained bronchiectasis.

  10. The cystic fibrosis of exocrine pancreas

    Wilschanski, Michael; Novak, Ivana


    The cystic fibrosis transmembrane conductance regulator (CFTR) protein is highly expressed in the pancreatic duct epithelia and permits anions and water to enter the ductal lumen. This results in an increased volume of alkaline fluid allowing the highly concentrated proteins secreted by the acinar...... cells to remain in a soluble state. This work will expound on the pathophysiology and pathology caused by the malfunctioning CFTR protein with special reference to ion transport and acid-base abnormalities both in humans and animal models. We will also discuss the relationship between cystic fibrosis...

  12. Sonographic-pathologic correlation of complex cystic breast lesions

    Saravech Pongrattanaman


    Full Text Available Objective: To understand the pathologic basis for sonographic features of complex cystic lesions. Methods: From 2 646 female patients underwent breast sonography at King Chulalongkorn Memorial Hospital from January 2005 through December 2010, 103 cystic lesions were included. Pathologic confirmation was performed by fine-needle aspiration (n=42, core needle biopsy (n=6, excision (n=54 and mastectomy (n=1. Complex cystic breast masses were classified into 3 types as followings; thick outer wall and/or thick internal septa (type I; thick septation and thick wall were defined as equal or more than 0.5 cm, masses containing mixed cystic and solid components (at least 50% of cystic component (type II, predominantly solid with eccentric cystic foci (at least 50% of solid component (type III. Results: In 103 complex cystic masses, there are 27 lesions (26% classified as type I cystic breast masses, 37 lesions (36% as type II cystic breast masses and 39 lesions (38% type III cystic breast masses, 26 lesions (25.2% are proved to be malignant. All of type I cystic breast masses in our study are benign, and 14 (38% of type II cystic breast masses and 12 lesions (31% of type III cystic breast lesions are proved to be malignant. Conclusions: Type II and III lesions should suggest possibility of malignancy and biopsy should be performed in all lesions. All type I lesion in this study are benign. None of other parameters we included in this study (size or margin can effectively differentiate between benign or malignant cystic breast lesions. Also, grading of the malignant lesions by using type of cystic breast mass cannot be applied.

  13. Aromatase is expressed and active in the rainbow trout oocyte during final oocyte maturation.

    Gohin, Maella; Bodinier, Pascal; Fostier, Alexis; Chesnel, Franck; Bobe, Julien


    While it is generally well accepted that the ovarian follicular sites of estradiol-17β (E2) synthesis are restricted to somatic cells, the possible contribution of the germinal compartment has received little or no attention in teleosts. In order to demonstrate the expression of ovarian aromatase in the oocyte, cyp19a1a mRNA was studied in ovarian follicles by in situ hybridization. In addition, the expression of cyp19a1a was studied in both somatic and germinal compartments of the ovarian follicle in rainbow trout (Oncorhynchus mykiss) during final oocyte maturation (i.e., maturational competence acquisition and subsequent meiosis resumption) by real-time PCR. The enzymatic activity of ovarian aromatase was also studied in both somatic and germinal compartments of the ovarian follicle. Finally, E2 levels were monitored in follicle-enclosed oocytes throughout the pre-ovulatory period. We were able to demonstrate a significant ovarian aromatase expression and activity in the late vitellogenic oocyte. Furthermore, a dramatic decrease in aromatase expression and activity occurs in the oocyte during late oogenesis, concomitantly with the trend observed in surrounding follicular layers. We also report an unexpected increase of E2 levels in the oocyte during the pre-ovulatory period. To our knowledge, these observations are reported for the first time in any teleost species. Together, our data support the hypothesis of the participation of the germinal compartment in follicular estrogen synthesis and a biological role of E2 during oocyte and/or early embryo development.

The article is divided into sections according to modality, covering rece...

  16. Cystic Eccrine Spiradenoma of the Finger Mimicking a Ganglion

    Khalid F. Jaber, MBChB


    Full Text Available Summary: We report a rare case of cystic eccrine spiradenoma in the finger. A 46-year-old man presented with a cystic mass in his left index finger. Clinical assessment along with the investigation pointed toward a diagnosis of a ganglion. However, excisional biopsy of the mass revealed histopathological findings of cystic eccrine spiradenoma. Very few cases of eccrine spiradenoma have been reported in the hand and none of them were cystic in consistency. We believe that this case will draw the surgeon’s attention to the possibility of unusual differential diagnoses in the evaluation and treatment of cystic lumps in the hand.

  17. Premature ovarian failure.

    Shelling, Andrew N


    Premature ovarian failure (POF) is a common cause of infertility in women, and is characterised by amenorrhoea, hypo-oestrogenism and elevated gonadotrophin levels in women under the age of 40. Known causes include iatrogenic agents that cause permanent damage to the ovaries, such as chemotherapy, radiation therapy and surgery, autoimmune conditions, X-chromosome abnormalities and autosomal genetic conditions. However, few genes have been identified that can explain a substantial proportion of cases of POF. Most women with POF are deeply upset by the diagnosis, partly due to the unexpected menopausal symptoms, but also due to infertility. Therefore, early detection would provide better opportunity for early intervention, and furthermore, the identification of specific gene defects will help to direct potential targets for future treatment.

  18. [Oxaliplatin and ovarian cancer].

    Dieras, Véronique; Girre, Véronique; Guilhaume, Marie-Noëlle; Laurence, Valérie; Mignot, Laurent


    Oxaliplatin was brought into clinical evaluation in ovarian cancer because of the in vitro and in vivo antitumor activity observed in experimental models resistant to cisplatin. As single agent at 130 mg/m2 every 3 weeks, the objective response rates rage from 16% to 29% in patients treated after failure of one or two regimens. As first line, in a randomized trial cyclophosphamide-cisplatin versus cyclophosphamide-oxaliplatine, no significant statistical differences were observed in efficacy parameters (response rate, progression free survival and overall survival). The toxicity profile seemed to favor the oxaliplatin arm. Many associations with other available active drugs as taxanes, gemcitabine and liposomal doxorubicin were performed with promising results.

  19. Polycystic ovarian syndrome

    Nina Madnani


    Full Text Available Polycystic ovarian syndrome (PCOS is a "multispeciality" disorder suspected in patients with irregular menses and clinical signs of hyperandrogenism such as acne, seborrhoea, hirsutism, irregular menses, infertility, and alopecia. Recently, PCOS has been associated with the metabolic syndrome. Patients may develop obesity, insulin resistance, acanthosis nigricans, Type 2 diabetes, dyslipidemias, hypertension, non-alcoholic liver disease, and obstructive sleep apnoea. Good clinical examination with hematological and radiological investigations is required for clinical evaluation. Management is a combined effort involving a dermatologist, endocrinologist, gynecologist, and nutritionist. Morbidity in addition includes a low "self image" and poor quality of life. Long term medications and lifestyle changes are essential for a successful outcome. This article focuses on understanding the normal and abnormal endocrine functions involved in the pathogenesis of PCOS. Proper diagnosis and management of the patient is discussed.

  20. Tamoxifen and ovarian function.

    Martine Berliere

    Full Text Available BACKGROUND: Some studies suggest that the clinical parameter "amenorrhea" is insufficient to define the menopausal status of women treated with chemotherapy or tamoxifen. In this study, we investigated and compared the ovarian function defined either by clinical or biological parameters in pre-menopausal breast cancer patients treated with tamoxifen administered as adjuvant therapy. MATERIALS AND METHODS: Between 1999 and 2003, 138 premenopausal patients consecutively treated for early breast cancer were included. Sixty-eight received tamoxifen in monotherapy as the only adjuvant systemic treatment (Group I and 70 were treated with tamoxifen after adjuvant chemotherapy (Group II. All patients had a confirmed premenopausal status based on clinical parameters and hormonal values at study entry. They were followed prospectively every 3 months for 3 years: menses data, physical examination and blood tests (LH, FSH, 17-beta-estradiol. Vaginal ultrasonography was carried out every 6 months. After 3 years, prospective evaluation was completed and monitoring of ovarian function was performed as usual in our institution (1x/year. All data were retrospectively evaluated in 2011. RESULTS: Three patients were excluded from the study in group I and 2 were excluded in group II. Patients were divided into 4 subgroups according to clinical data, i.e. menses patterns. These patterns were assessed by questionnaires. a: Regular menses (>10 cycles/year b: Oligomenorrhea (5 to 9 cycles/year c: Severe oligomenorrhea (1 to 4 cycles/year d: Complete amenorrhea Estrogen levels did not appear to have any impact on disease-free survival rates after 3 or 8 years. FSH values were also documented and analyzed. They exhibited the same profile as estradiol values. CONCLUSIONS: Amenorrhea is an insufficient parameter to define menopausal status in patients receiving tamoxifen. Low estradiol levels must be coupled with other biological parameters to characterize endocrine status

  1. Doxorubicin-induced ovarian toxicity

    Rizel Shulamith


    Full Text Available Abstract Background Young cancer patients may occasionally face infertility and premature gonadal failure. Apart from its direct effect on follicles and oocytes, chemotherapy may induce ovarian toxicity via an impact on the entire ovary. The role of doxorubicin in potential ovarian failure remains obscure. Our intention was to elucidate doxorubicin-related toxicity within ovaries. Methods Female mice were injected intraperitoneally with 7.5 or 10 mg/kg doxorubicin and their ovaries were visualized in vivo by high resolution MRI, one day and one month following treatment. Ovaries of other treated mice were excised and weighed at the same post-treatment intervals. Ovarian histological sections were stained for TUNEL or active caspase-3 and follicles were counted and categorized. Ovulation rates were evaluated in superovulated female mice treated with doxorubicin. Results A single injection of doxorubicin resulted in a major reduction in both ovarian size and weight that lasted even one month post treatment. A dramatic reduction in ovulation rate was observed one week after treatment, followed by a partial recovery at one month. Histological examination revealed positive staining of TUNEL and active caspase-3. We observed a significant reduction in the population of secondary and primordial follicles one month following treatment. Conclusions Our results may imply a mechanism of chemotherapy-induced ovarian toxicity, manifested by reduced ovulation and accompanied by a reduction in ovarian size, caused probably by an acute insult to the ovary.

  2. Infertility in females with cystic fibrosis is multifactorial: evidence from mouse models.

    Hodges, Craig A; Palmert, Mark R; Drumm, Mitchell L


    Infertility is commonly associated with cystic fibrosis (CF). Although infertility in men with CF has been thoroughly investigated, the infertility observed in women with CF has not been well studied. To investigate female infertility associated with CF, we used two independently derived mouse models of CF. Both of these models displayed decreased fertility characterized by a reduction in litter number and litter size. Our findings suggest that much of the reduced fertility in these mice originates from decreased fertilization due to inadequate sperm transport within the female reproductive tract. However, our data indicate that additional reproductive phenotypes in the CF female mice also contribute to the reduced fertility including small ovarian and uterine size, aberrant estrous cycles, and decreased oocyte ovulation rates. These data, along with previous work demonstrating that the gene mutated in CF, the cystic fibrosis transmembrane conductance regulator (CFTR), is normally expressed in tissues vital to reproduction, raises the possibility that CFTR may have a direct effect on fertility. If so, CFTR may also play an important role in normal female fertility within the general population.

  3. Folliculosebaceous Cystic Hamartoma With Spindle Cell Lipoma-Like Stromal Features.

    Nguyen, Catherine M; Skupsky, Hadas; Cassarino, David


    Folliculosebaceous cystic hamartoma is a distinctive cutaneous hamartoma composed of follicular, sebaceous, and mesenchymal components. The lesions are most commonly found on the face and scalp of young adults, with approximately 30% occurring in the nasal or paranasal regions of the face. The clinical differential diagnoses are extensive and include epidermoid cyst, dermal nevus, soft fibroma, and adnexal tumors including sebaceous neoplasms. Here, the authors present a case of a 24-year-old man who presented for evaluation of an asymptomatic growth on the nose, which had slowly enlarged over 9 years. On examination, there was a 0.6 cm dome-shaped flesh-colored papule on the nasal bridge. The clinical differential included dermatofibroma versus intradermal nevus. A shave biopsy was performed, and histological examination of the sections showed a proliferation of multiple enlarged and irregular-appearing sebaceous glands attached to a cystic follicular structure. The associated dermal mesenchymal component consisted of numerous mature-appearing adipocytes associated with a fibromyxoid stroma, prominent collections of mucin, and bundles of ropey collagen resembling a spindle cell lipoma. This combination of a folliculosebaceous cystic hamartoma with a spindle cell lipoma-like mesenchymal proliferation is unusual and has not been previously reported.

  5. Left ventricular diastolic function in patients with advanced cystic fibrosis.

    Koelling, Todd M; Dec, G William; Ginns, Leo C; Semigran, Marc J


    To assess left ventricular systolic and diastolic function in adult patients with cystic fibrosis using radionuclide ventriculography. Although myocardial fibrosis has been described in autopsy specimens of patients with cystic fibrosis, the possibility that myocardial dysfunction may occur during life in adult patients with cystic fibrosis has not been explored. To assess the possibility of cardiac dysfunction occurring in cystic fibrosis, we studied 40 patients with advanced cystic fibrosis with first-pass radionuclide ventriculography and compared them to 9 patients with advanced bronchiectasis and 18 normal control subjects. Indexes of right ventricular systolic function were similarly impaired in patients with cystic fibrosis and patients with bronchiectasis. Left ventricular ejection fraction of patients with cystic fibrosis, patients with bronchiectasis, and normal control subjects did not differ. Fractional left ventricular filling at 50% of diastole, an index of diastolic function, was significantly lower in patients with cystic fibrosis (54 +/- 13%, mean +/- SD) in comparison to patients with bronchiectasis (66 +/- 4%, p = 0.009) or normal control subjects (69 +/- 14, p = 0.0002). The contribution of atrial systole to total diastolic left ventricular filling was greater in patients with cystic fibrosis (38 +/- 18%) than in patients with bronchiectasis (21 +/- 4%, p = 0.01) or normal control subjects (25 +/- 12%, p = 0.01). Patients with advanced cystic fibrosis demonstrate impaired left ventricular distensibility when compared to normal control subjects and patients with bronchiectasis. Patients with cystic fibrosis may be at risk of heart failure due to right ventricular dysfunction or left ventricular diastolic dysfunction.

  6. Alginate encapsulation supports the growth and differentiation of human primordial follicles within ovarian cortical tissue.

    Laronda, Monica M; Duncan, Francesca E; Hornick, Jessica E; Xu, Min; Pahnke, Jennifer E; Whelan, Kelly A; Shea, Lonnie D; Woodruff, Teresa K


    In vitro follicle growth (IVFG) is an investigational fertility preservation technique in which immature follicles are grown in culture to produce mature eggs that can ultimately be fertilized. Although progress has been made in growing primate primary and secondary follicles in vitro, it has been a relatively greater challenge to isolate and culture primordial follicles. The purpose of this study was to develop methods to grow human primordial follicles in vitro using alginate hydrogels. We obtained human ovarian tissue for research purposes through the National Physicians Cooperative from nationwide sites and used it to test two methods for culturing primordial follicles. First, primordial follicles were isolated from the ovarian cortex and encapsulated in alginate hydrogels. Second, 1 mm × 1 mm pieces of 500 μm-thick human ovarian cortex containing primordial follicles were encapsulated in alginate hydrogels, and survival and follicle development within the tissue was assessed for up to 6 weeks. We found that human ovarian tissue could be kept at 4 °C for up to 24 h while still maintaining follicle viability. Primordial follicles isolated from ovarian tissue did not survive culture. However, encapsulation and culture of ovarian cortical pieces supported the survival, differentiation, and growth of primordial and primary follicles. Within several weeks of culture, many of the ovarian tissue pieces had formed a defined surface epithelium and contained growing preantral and antral follicles. The early stages of in vitro human follicle development require the support of the native ovarian cortex.

    Christiansen, Charlotte


    The paper aims to improve the knowledge of the empirical properties of the long maturity region of the forward rate curve. Firstly, the theoretical negative correlation between the slope at the long end of the forward rate curve and the term structure variance is recovered empirically and found...... to be statistically significant. Secondly, the expectations hypothesis is analyzed for the long maturity region of the forward rate curve using "forward rate" regressions. The expectations hypothesis is numerically close to being accepted but is statistically rejected. The findings provide mixed support...

  10. Sympathetic nerve activity in normal and cystic follicles from isolated bovine ovary: local effect of beta-adrenergic stimulation on steroid secretion

    Ortega Hugo H


    Full Text Available Abstract Cystic ovarian disease (COD is an important cause of abnormal estrous behavior and infertility in dairy cows. COD is mainly observed in high-yielding dairy cows during the first months post-partum, a period of high stress. We have previously reported that, in lower mammals, stress induces a cystic condition similar to the polycystic ovary syndrome in humans and that stress is a definitive component in the human pathology. To know if COD in cows is also associated with high sympathetic activity, we studied isolated small antral (5mm, preovulatory (10mm and cystic follicles (25mm. Cystic follicles which present an area 600 fold greater compared with preovulatory follicles has only 10 times less concentration of NE as compared with small antral and preovulatory follicles but they had 10 times more NE in follicular fluid, suggesting a high efflux of neurotransmitter from the cyst wall. This suggestion was reinforced by the high basal release of recently taken-up 3H-NE found in cystic follicles. While lower levels of beta-adrenergic receptor were found in cystic follicles, there was a heightened response to the beta-adrenergic agonist isoproterenol and to hCG, as measured by testosterone secretion. There was however an unexpected capacity of the ovary in vitro to produce cortisol and to secrete it in response to hCG but not to isoproterenol. These data suggest that, during COD, the bovine ovary is under high sympathetic nerve activity that in addition to an increased response to hCG in cortisol secretion could participate in COD development.

  11. Cystic lesion around the hip joint

    Yukata, Kiminori; Nakai, Sho; Goto, Tomohiro; Ikeda, Yuichi; Shimaoka, Yasunori; Yamanaka, Issei; Sairyo, Koichi; Hamawaki, Jun-ichi


    This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder. Treatment for symptomatic cystic lesions around the hip joint includes rest, nonsteroidal anti-inflammatory drug administration, needle aspiration, and surgical excision. Furthermore, when these cysts are associated with osteoarthritis, rheumatoid arthritis, and THA, primary or revision THA surgery will be necessary concurrent with cyst excision. Knowledge of the characteristic clinical appearance of cystic masses around the hip will be useful for determining specific diagnoses and treatments. PMID:26495246

  17. Craniofacial morphology in children with cystic fibrosis.

    Hellsing, E; Brattström, V; Strandvik, B


    Cystic fibrosis (CF) is a hereditary metabolic disorder with clinical symptoms of abnormal mucus production. This blocks the airways, gives pancreatic insufficiency, and increases sweat electrolytes. The progressive respiratory disease often leads to respiratory insufficiency and cor pulmonale. The aim of the present investigation was to examine the facial morphology in children with cystic fibrosis. The sample comprised 11 children with cystic fibrosis, who were divided in two groups, one with gastrointestinal disorders and the other with predominantly respiratory insufficiency. Eleven healthy children with normal occlusions were selected as controls. Lateral skull radiographs obtained in natural head posture were digitized, and linear and angular variables for the different groups calculated and compared statistically. The cystic fibrosis group showed open bite, decreased posterior facial height, increased mandibular and craniocervical inclination. Additionally, within the CF-group, the children with respiratory insufficiency differed more from the controls than the children with gastrointestinal disorders. Despite the small number of subjects, the facial morphology of the CF children showed a similar pattern to that of children with nasal respiratory obstruction due to enlarged adenoids or tonsils.

  7. 高反应人群超排卵%Controlled ovarian stimulation for high responder women undergoing in vitro fertilization



    High responder women are characterized by high response to exogenous gonadotrophin therapy manifested hy recruitment of a large number of follicles, rapid estradiol response and significant cancellation rate due to the potential risk of ovarian hyperstimulation syndrome (OHSS) during in vitro fertilization-embryo transfer. Even for those patients who progress to oocyte retrieval and embryo transfer, appreciably lower fertilization rate and chromosomally normal blastocyst development rate are found. The super ovulation strategies for high responder women are included to reduce excessive ovarian stimulation and avoid OHSS by several approaches, such as dual suppression with oral contraceptives and GnRH agonist, reduced doses of GnRH agonist, GnRH antagonist protocol and GnRH agonist instead of hCG to trigger the final oocyte maturation, gonadotrophins step up and step down, different gonadotrophins for ovarian stimulation, application of metf ormin, and mild ovarian stimulation.

  8. Nutrient Status of Adults with Cystic Fibrosis



    Nutrition is thought to influence disease status in patients with cystic fibrosis (CF). This cross-sectional study sought to evaluate nutrient intake and anthropometric data from 64 adult outpatients with cystic fibrosis. Nutrient intake from food and supplements was compared with the Dietary Reference Intakes for 16 nutrients and outcomes influenced by nutritional status. Attention was given to vitamin D and calcium given potential skeletal implications due to cystic fibrosis. Measurements included weight, height, body composition, pulmonary function, and serum metabolic parameters. Participants were interviewed about dietary intake, supplement use, pulmonary function, sunlight exposure, and pain. The participants’ mean body mass index (±standard deviation) was 21.8±4.9 and pulmonary function tests were normal. Seventy-eight percent used pancreatic enzyme replacement for malabsorption. Vitamin D deficiency [25-hydroxyvitamin D (25OHD)<37.5 nmol/L] was common: 25 (39%) were deficient despite adequate vitamin D intake. Lipid profiles were normal in the majority, even though total and saturated fat consumption represented 33.0% and 16.8% of energy intake, respectively. Reported protein intake represented 16.9% of total energy intake (range 10%–25%). For several nutrients, including vitamin D and calcium, intake from food and supplements in many participants exceeded recommended Tolerable Upper Intake Levels. Among adults with cystic fibrosis, vitamin D deficiency was common despite reported adequate intake, and lipid profiles were normal despite a relatively high fat intake. Mean protein consumption was adequate, but the range of intake was concerning, as both inadequate or excessive intake may have deleterious skeletal effects. These findings call into question the applicability of established nutrient thresholds for patients with cystic fibrosis. PMID:18060897

  18. Probiotic supplementation in children with cystic fibrosis-a systematic review.

    Ananthan, Anitha; Balasubramanian, Haribalakrishna; Rao, Shripada; Patole, Sanjay


    Probiotics may benefit in cystic fibrosis (CF) as gut dysbiosis is associated with gastrointestinal symptoms and exacerbation of respiratory symptoms in CF. We conducted a systematic review of randomized controlled trials (RCTs) and non-RCTs of probiotic supplementation in children with CF, using the Cochrane methodology, preferred reporting items for systematic reviews (PRISMA) statement, and meta-analysis of observational studies in epidemiology (MOOSE) guidelines. Primary outcomes were pulmonary exacerbations, duration of hospitalization and antibiotics, and all-cause mortality. Secondary outcomes included gastrointestinal symptoms, markers of gut inflammation, and intestinal microbial balance. A total of nine studies (RCTs, 6, non-RCTs, 3; N = 275) with some methodological weaknesses were included in the review. The pooled estimate showed significant reduction in the rate of pulmonary exacerbation (fixed effects model, two parallel group RCTs and one cross-over trial: relative risk (RR) 0.25, (95 % confidence interval (95 % CI) 0.15,0.41); p Bacteroides in one RCT, one non-RCT). Limited low-quality evidence exists on the effects of probiotics in children with CF. Well-designed adequately powered RCTs assessing clinically meaningful outcomes are required to study this important issue. • Gut dysbiosis is frequent in children with cystic fibrosis due to frequent exposure to pathogens and antibiotics. • Probiotics decrease gut dysbiosis and improve gut maturity and function. What is New: • This comprehensive systematic review shows that current evidence on the safety and efficacy of probiotics in children with cystic fibrosis is limited and of low quality. • Well-designed and adequately powered trials assessing clinically important outcomes are required considering the health burden of cystic fibrosis and the potential benefits of probiotics.

  19. Revisiting ovarian hyper stimulation syndrome: Towards OHSS free clinic

    Manish Banker


    Full Text Available A rapid development and application of assisted reproductive technologies (ARTs and ovulation-induction drugs may lead to ovarian hyper stimulation syndrome (OHSS. Young age, low body mass index (BMI, polycystic ovarian syndrome (PCOS, previous OHSS, high follicle count, and elevated serum estradiol (E2 are the certain factors that predispose women to OHSS. Many strategies have been used to reduce or avoid OHSS. Use of human chorionic gonadotropin (hCG increases ovarian vascular permeability and is responsible for activating the vascular endothelial growth factors (VEGF pathway and thus the entire cascade, leading to symptomatic OHSS. Gonadotropin-releasing hormone (GnRH agonists are used as a replacement for hCG for final oocyte maturation in antagonist cycles. Reducing or eliminating the use of hCG and use of GnRH agonist triggered GnRH antagonist cycles and cryopreservation of oocytes or embryos is the most promising approach in making OHSS free clinic a reality.

  20. Melatonin, a possible promising panacea for premature ovarian failure

    Ting Guo


    Full Text Available Premature ovarian failure (POF is characterized by impairment of ovarian function unrelated to elevatedfollicle-stimulating hormone (FSH before the age of 40. The consequence of POF is severe and distinctive, presentingfrom infertility to symptoms caused by hormone deprivation. The mechanism of POF remains unclearand current treatments are therefore ineffective. Melatonin (N-acetyl-5-methoxytryptamine is a neuroendocrinalhormone chiefly secreted by the pineal body. Melatonin exerts extensive physiological and pharmacologicaleffects on the biological rhythm, oxidative stress, reproduction, autoimmune and tumourigenesis. However,current researches have not yet brought melatonin into the study of POF. In the present review, we have involvedstate-of-the-art research progress of melatonin in ovary with regard to oxidation, follicle formation and function,and ovarian autoimmune disorders since these aspects mainly dispose to POF development. The features thatmelatonin scavenges reactive oxygen species (ROS, directly and indirectly induces follicle maturation, ovulationand inhibits apoptosis, and modulates autoimmune derangements in the ovaries are highly indicative that melatonincan effect in combating POF. Also, in this respect we have discussed the possibility of applying melatoninin the treatment of POF and have listed evidence of studies in vitro and in vivo. Vacant research directions aresubsequently suggested and the future application of melatonin in POF treatment is prospected.

  2. Huge bilateral ovarian cysts in adulthood as the presenting feature of Van Wyk Grumbach syndrome due to chronic uncontrolled juvenile hypothyroidism

    K S Shivaprasad


    Full Text Available Juvenile primary hypothyroidism causing cystic ovaries and pseudoprecocious puberty (Van-Wyk Grumbach syndrome (VWGS is well documented in literature. There are only a few reports of primary hypothyroidism presenting as ovarian cysts in adults. Here we present a case of huge bilateral ovarian cysts in adulthood as the presenting feature of VWGS due to chronic uncontrolled juvenile hypothyroidism. Large uniloculor right ovarian cyst (119 × 81 × 90 mm and a multicystic left ovary (55 × 45 × 49 mm were detected in a 24 year lady with secondary amenorrhea, galactorrhea, and palpable abdominal mass with history of neonatal jaundice, delayed milestones, short stature, and precocious menarche at age of 7.5 years age. She had elevated levels of cancer antigen (CA-125 which normalized post levothyroxine supplementation. Elevated CA-125 may lead to misdiagnosis of ovarian carcinoma and inadvertent treatment. Bilateral ovarian cysts in adults are a rare presentation of juvenile hypothyroidism. It is necessary to screen for primary hypothyroidism in patients presenting with bilateral ovarian cysts to prevent unnecessary evaluation and treatment.

  3. HemoHIM improves ovarian morphology and decreases expression of nerve growth factor in rats with steroid-induced polycystic ovaries.

    Kim, Sung Ho; Lee, Hae June; Kim, Joong Sun; Moon, Changjong; Kim, Jong Choon; Bae, Chun Sik; Park, Hae Ran; Jung, Uhee; Jo, Sung Kee


    Estradiol valerate (EV)-induced polycystic ovaries (PCOs) in rats cause the anovulation and cystic ovarian morphology. We investigated whether treatment with HemoHIM influences the ovarian morphology and the expression of nerve growth factor (NGF) in an EV-induced PCO rat model. PCO was induced by a single intramuscular injection of EV (4 mg, dissolved in sesame oil) in adult cycling rats. HemoHIM was either administered orally (100 mg/kg of body weight/day) for 35 consecutive days or injected intraperitoneally (50 mg/kg of body weight) every other day after EV injection. Ovarian morphology was almost normalized, and NGF was normalized in the PCO + HemoHIM group. HemoHIM lowered the high numbers of antral follicles and increased the number of corpora lutea in PCOs. The results are consistent with a beneficial effect of HemoHIM in the prevention and treatment of PCO syndrome.


    Marína Medveďová


    Full Text Available During the 20th century, there has been an increased risk from environmental by-products that may be harmful to reproductive function in humans. Therefore, as the 21th century begins, it is appropriate to evaluate future directions within the field of reproductive toxicology. Increasingly, the enzymes involved in the steroid biosynthesis pathway are being recognized as important targets for the actions of various endocrine-disrupting chemicals. Studies in vivo and in vitro focused on the ovarian and testicular function. Ovarian steroid production and subsequent local steroid-mediated signaling are critical for normal ovarian processes, including follicle growth, oocyte maturation, and ovulation. Through the use of several in vitro models, great strides were made toward characterizing the mechanisms regulating local steroid production and action in ovary. This review aims to provide a comprehensive overview of the state of knowledge regarding the mechanisms by which mycotoxins interfere with the function of steroidogenic enzymes in various tissues and organisms.

  5. Tubo-ovarian Actinomycosis Mimicking Ovarian Malignancy: Case Report

    Faten Limaiem


    Full Text Available Actinomycosis is a chronic suppurative granulomatous infection caused by Actinomyces israelii, an anaerobic Gram-positive microorganism. Pelvic actinomycosis is rare and constitutes 3% of all human actinomycosis infections. Pre-operative diagnosis is usually difficult with the majority of cases being diagnosed after the histological and bacteriological examination of the resected specimen. In this paper, the authors report a new case of tubo-ovarian actinomycosis in a 42-year-old woman that was misdiagnosed pre-operatively as ovarian malignancy. Tubo-ovarian actinomycosis should be considered in patients with a pelvic mass especially in ones using intra-uterine devices. Surgeons should be aware of this infection in order to avoid excessive surgical procedures. [J Interdiscipl Histopathol 2015; 3(3.000: 117-119

    Park, Chan Woo; Lee, Sun Hee; Yang, Kwang Moon; Lee, In Ho; Lim, Kyung Teak; Lee, Ki Heon


    Objective The aim of this study was to report a case series of in vitro matured (IVM) oocyte freezing in gynecologic cancer patients undergoing radical surgery under time constraints as an option for fertility preservation (FP). Methods Case series report. University-based in vitro fertilization center. Six gynecologic cancer patients who were scheduled to undergo radical surgery the next day were referred for FP. The patients had endometrial (n=2), ovarian (n=3), and double primary endometrial and ovarian (n=1) cancer. Ex vivo retrieval of immature oocytes from macroscopically normal ovarian tissue was followed by mature oocyte freezing after IVM or embryo freezing with intracytoplasmic sperm injection. Results A total of 53 oocytes were retrieved from five patients, with a mean of 10.6 oocytes per patient. After IVM, a total of 36 mature oocytes were obtained, demonstrating a 67.9% maturation rate. With regard to the ovarian cancer patients, seven IVM oocytes were frozen from patient 3, who had stage IC cancer, whereas one IVM oocyte was frozen from patient 4, who had stage IV cancer despite being of a similar age. With regard to the endometrial cancer patients, 15 IVM oocytes from patient 1 were frozen. Five embryos were frozen after the fertilization of IVM oocytes from patient 6. Conclusion Immature oocytes can be successfully retrieved ex vivo from macroscopically normal ovarian tissue before radical surgery. IVM oocyte freezing provides a possible FP option in patients with advanced-stage endometrial or ovarian cancer without the risk of cancer cell spillage or time delays. PMID:27358831

    Fog, Sigrid Marie Kasper Kasper; Dueholm, Margit; Marinovskij, Edvard;


    OBJECTIVE: To analyze the ability of magnetic resonance imaging (MRI) and systematic evaluation at surgery to predict optimal cytoreduction in primary advanced ovarian cancer and to develop a preoperative scoring system for cancer staging. STUDY DESIGN: Preoperative MRI and standard laparotomy were...... performed in 99 women with either ovarian or primary peritoneal cancer. Using univariate and multivariate logistic regression analysis of a systematic description of the tumor in nine abdominal compartments obtained by MRI and during surgery plus clinical parameters, a scoring system was designed....... MRI is able to assess ovarian cancer with peritoneal carcinomatosis with satisfactory concordance with laparotomic findings. This scoring system could be useful as a clinical guideline and should be evaluated and developed further in larger studies....

  10. Maturity in technology

    L. Alberts


    Full Text Available The concept is developed that modern technology, because of its relationship with pure science, can never really become mature, but will always grow as the pool of scientific knowledge grows. Parameters indicating to some extent the degree of technological prowess in a society are compared for a spectrum of countries. It is clear that in spite of some internationally outstanding successes. South Africa must be regarded on average as a developing society.

  11. Ovarian Transcriptome Analysis of Vitellogenic and Non-Vitellogenic Female Banana Shrimp (Fenneropenaeus merguiensis)

    Saetan, Uraipan; Sangket, Unitsa; Deachamag, Panchalika; Chotigeat, Wilaiwan


    The banana shrimp (Fenneropenaeus merguiensis) is one of the most commercially important penaeid species in the world. Its numbers are declining in the wild, leading to a loss of broodstock for farmers of the shrimp and a need for more successful breeding programs. However, the molecular mechanism of the genes involved in this shrimp’s ovarian maturation is still unclear. Consequently, we compared transcriptomic profiles of ovarian tissue from females in both the vitellogenic stage and the non-vitellogenic stage. Using RNA-Seq technology to prepare the transcriptome libraries, a total of 12,187,412 and 11,694,326 sequencing reads were acquired from the non-vitellogenic and vitellogenic stages respectively. The analysis of the differentially expressed genes identified 1,025 which were significantly differentially expressed between the two stages, of which 694 were up-regulated and 331 down-regulated. Four genes putatively involved in the ovarian maturation pathway were chosen for validation by quantitative real-time PCR (RT-qPCR). The data from this study provided information about gene expression in ovarian tissue of the banana shrimp which could be useful for a better understanding of the regulation of this species’ reproductive cycle.

  12. Role of juvenile hormone and allatotropin on nutrient allocation, ovarian development and survivorship in mosquitoes.

    Hernández-Martínez, Salvador; Mayoral, Jaime G; Li, Yiping; Noriega, Fernando G


    Teneral reserves are utilized to initiate previtellogenic ovarian development in mosquitoes. Females having emerged with low teneral reserves have reduced juvenile hormone (JH) synthesis and previtellogenic development. We investigated what role JH, allatotropin (AT) and other head-factors play in the regulation of previtellogenic ovarian development and adult survivorship. Factors from the head are essential for corpora allata (CA) activation and reproductive maturation. We have shown that decapitation of females within 9-12h after adult ecdysis prevented normal development of the previtellogenic follicles; however maximum previtellogenic ovarian development could be induced in decapitated females by topically applying a JH analog. When females were decapitated 12 or more hours after emergence nutritional resources had been committed to ovarian development and survivorship was significantly reduced. To study if allatotropin levels correlated with teneral reserves, we measured AT titers in the heads of two adult phenotypes (large and small females) generated by raising larvae under different nutritional diets. In large mosquitoes AT levels increased to a maximum of 45 fmol in day 4; in contrast, the levels of allatotropin in the heads of small mosquitoes remained below 9 fmol during the 7 days evaluated. These results suggest that only when nutrients are appropriate, factors released from the brain induce the CA to synthesize enough JH to activate reproductive maturation.

  14. MUC1 in endometriosis and ovarian cancer.

    Vlad, Anda M; Diaconu, Iulia; Gantt, Kira R


    Endometriosis is a chronic, debilitating disease, associated with pelvic pain and infertility. Recent epidemiological studies suggest that women with endometriosis are at increased risk for ovarian cancer. Although the causative factors for both endometriosis and ovarian cancer remain largely unknown, several similarities between the proposed etiology of ovarian cancer and the observed pathophysiology of endometriosis have been reported. MUC1 glycoprotein is present in endometriotic lesions and overexpressed in epithelial ovarian tumors. We are currently studying immunity to MUC1 antigen in newly emerging preclinical models for endometriosis and ovarian cancer and exploring the potential for immune therapy/prevention with MUC1 in both diseases.

  15. Giant mediastinal mature teratoma with increased exocrine pancreatic activity presenting in a young woman: a case report

    Davoli Fabio


    Full Text Available Abstract Introduction Mediastinal mature teratoma is a benign, slow-growing tumor typically affecting 20- to 40-year-old adults. Fluid examination from the cystic masses rarely shows enzymatic activity as we describe in this report. Case presentation We report a case of a giant mediastinal germ cell tumor (measuring 15 cm × 14 cm × 8 cm detected in a 35-year-old Caucasian woman. Microscopic examination showed that the lesion resembled a mature cystic teratoma with areas of pancreatic tissue with mature ductal and acinar structures intermixed with islets of Langerhans. Fluid from the cysts in the mass was examined after removal showed amylase activity of 599 U/l despite normal serum levels. The post-operative period was free of complications, and the patient was discharged on post-operative day 10. Conclusion Complete surgical removal is the treatment of choice for mature cystic teratomas, with optimal results and acceptable surgical risk. Exocrine pancreatic function may be an aid to pre-operative or intra-operative diagnosis; however, these findings have no impact on survival or the therapeutic pathway.

  17. PARP inhibitors in ovarian cancer.

    Ledermann, J A


    Slow progress in improving the outcome of ovarian cancer with chemotherapy over the last decade has stimulated research into molecularly targeted therapy. Poly(ADP-ribose) polymerase (PARP) inhibitors target DNA repair and are specifically active in cells that have impaired repair of DNA by the homologous recombination (HR) pathway. Cells with mutated BRCA function have HR deficiency (HRD), which is also present in a significant proportion of non-BRCA-mutated ovarian cancer. In the last decade, olaparib, the first and most-investigated oral PARP inhibitor, has undergone phase I-III trials as a single agent, in comparison with and in addition to chemotherapy, and as a maintenance therapy following chemotherapy. The greatest benefit to-date has been in the maintenance setting, prolonging the progression-free survival of high-grade serous ovarian cancer with a BRCA1/2 mutation. In this group of patients, olaparib has received approval as maintenance following chemotherapy from the EMA, and accelerated approval as a single agent in women who have had three or more lines of therapy. Olaparib can be given for a prolonged period with few significant side-effects in most patients. Similar trials with other PARP inhibitors (rucaparib, niraparib and veliparib) are in progress and include non-BRCA-mutated ovarian cancer. Second-generation studies are exploring the combination of PARP inhibitors with anti-angiogenic drugs. PARP inhibitors represent a step change in the management of ovarian cancer. BRCA mutations are the first genotypic predictive markers in ovarian cancer and can be used to select patients who will most likely benefit from PARP inhibitors. BRCA testing is now becoming a routine part of the evaluation of women with ovarian cancer, and tests for HRD are being used to evaluate PARP inhibitors in an extended population of non-BRCA-mutated ovarian cancer. © The Author 2016.

  18. Inflammation and its genesis in cystic fibrosis.

    Nichols, David P; Chmiel, James F


    The host inflammatory response in cystic fibrosis (CF) lung disease has long been recognized as a central pathological feature and an important therapeutic target. Indeed, many believe that bronchiectasis results largely from the oxidative and proteolytic damage comprised within an exuberant airway inflammatory response that is dominated by neutrophils. In this review, we address the longstanding argument of whether or not the inflammatory response is directly attributable to impairment of the cystic fibrosis transmembrane conductance regulator or only secondary to airway obstruction and chronic bacterial infection and challenge the importance of this distinction in the context of therapy. We also review the centrality of neutrophils in CF lung pathophysiology and highlight more recent data that suggest the importance of other cell types and signaling beyond NF-κB activation. We discuss how protease and redox imbalance are critical factors in CF airway inflammation and end by reviewing some of the more promising therapeutic approaches now under development.

  19. Cystic fibrosis lung disease in adult patients.

    Vender, Robert L


    As the longevity of all patients with cystic fibrosis (CF) continues to increase (median 2005 survival=36.8 years), more adult patients will be receiving their medical care from nonpediatric adult-care providers. Cystic fibrosis remains a fatal disease, with more than 80% of patients dying after the age of 18 years, and most deaths resulting from pulmonary disease. The changing epidemiology requires adult-care providers to become knowledgeable and competent in the clinical management of adults with CF. Physicians must understand the influence of specific genotype on phenotypic disease presentation and severity, the pathogenic factors determining lung disease onset and progression, the impact of comorbid disease factors such as CF-related diabetes and malnutrition upon lung disease severity, and the currently approved or standard accepted therapies used for chronic management of CF lung disease. This knowledge is critical to help alleviate morbidity and improve mortality for the rapidly expanding population of adults with CF.

  1. In vitro fertilization and embryo transfer in seminatural cycles for patients with ovarian aging.

    Castelo Branco, Altina; Achour-Frydman, Nelly; Kadoch, Jacques; Fanchin, Renato; Tachdjian, Gerard; Frydman, René


    To investigate whether seminatural cycle is a reasonable management for ovarian aging patients. Prospective study. ART Unit, Clamart, France. Seventy-five women, 158 cycles. Infertile women who presented with ovarian aging (defined as low ovarian reserve and characterized by cycle day 3 high FSH, high E2, and/or low inhibin B and/or previous cycle cancellations due to poor ovarian response to COH) were studied. Patients were offered up to three cycles. Treatment was scheduled as follows. From cycle day 8 onward the selection of the dominant follicle was monitored by ultrasound and hormonal measurements. When the dominant follicle appeared, patients received GnRH antagonist and, thereafter, hMG to support further follicular development. Implantation rate and clinical pregnancy. Twenty-eight of 158 cycles were cancelled (17.7%). Oocyte pickups were performed in 119 (75.3%) cycles, 91 (57.6%) mature oocytes were retrieved, and 67 (42.4%) embryos transferred. Nineteen clinical pregnancies were obtained; the cumulative pregnancy rate per patient, after 3 cycles, was 35.2%. Use of a seminatural cycle is a reasonable management for patients with ovarian aging who have ovulatory menstrual cycles. It achieves a high implantation rate (28.3%).

    We prospectively studied 298 patients with cystic fibrosis (mean age 11.3 years; range 2 months to 32 years; sex ratio, 0.47) for nontuberculous mycobacteria in respiratory samples from January 1, 1996, to December 31, 1999. Mycobacterium abscessus was by far the most prevalent nontuberculous mycobacterium: 15 patients (6 male, 9 female; mean age 11.9 years; range 2.5–22 years) had at least one positive sample for this microorganism (versus 6 patients positive for M. avium complex), including 10 with >3 positive samples (versus 3 patients for M. avium complex). The M. abscessus isolates from 14 patients were typed by pulsed-field gel electrophoresis: each of the 14 patients harbored a unique strain, ruling out a common environmental reservoir or person-to-person transmission. Water samples collected in the cystic fibrosis center were negative for M. abscessus. This major mycobacterial pathogen in children and teenagers with cystic fibrosis does not appear to be acquired nosocomially. PMID:14720400

  6. A case of cystic hemangioma in mesentery

    Makoto Komura


    Full Text Available A nine-year-old, otherwise healthy girl presented with abdominal pain. On exam, there was a palpable cystic tumor in the left abdomen. According to imaging examinations, we tentatively diagnosed the tumor as lymphangioma of mesentery with bleeding. We planned to perform laparoscopic surgery to remove the tumor. On laparoscopy, cyst aspiration was performed to reduce the volume of the cysts, and the aspirated fluid was found to contain red blood cells. Due to technical difficulties, laparoscopic surgery was converted to open surgery. RBCs were detected in the cyst fluid at the sigmoid colon and intestinal mesentery. Resection of the cystic tumor and sigmoidectomy were performed. On pathologic examination of the tumor, there were multiple cysts but there was no cavernous part. The largest cyst was 6 × 5 × 3 cm. Simple squamous epithelium cells were found along parts of the inner lining of enlarged luminal cysts. On immunohistochemical staining, the tumor was positive for CD31 and CD34, and negative on D2-40 antibody staining. Therefore, we diagnosed this specimen as hemangioma with giant cysts at the mesentery. We conclude that bleeding into cysts of a hemangioma of mesentery might lead to the development of giant cysts and, in turn, a cystic tumor in the abdomen.

[Campus Virchow-Klinikum, Klinik fuer Geburtsmedizin, Berlin (Germany); Schwabe, M. [Campus Mitte, Inst. fuer Pathologie, Berlin (Germany); Wauer, R. [Campus Mitte, Klinik fuer Neonatologie, Berlin (Germany)


    Purpose: The aim of the study concerning congenital cystic lung malformations was to evaluate prenatal diagnoses postnatally to determine prognostic factors as well as to define optimized perinatal management. Materials and Methods: The study is based on 45 prenatal ultrasound examinations depicting fetal cystic lung lesions. 32 of the mothers had follow-up examinations. 5 pregnancies were terminated due to CCAM and additional malformations. Complete regression of the lesions was seen prenatally in 8 cases and postnatally in 5 children. Results: Surgical intervention due to respiratory insufficiency was necessary in 4 neonates. According to the imaging results, CCAM was present in 4 cases and sequestration in 7 patients. No correlation between the imaging findings and the surgical results was found in 3 children: One child suffered from rhadomyoid dysplasia, and in the case of the second child, a left-sided hernia of the diaphragm and additional sequestration were detected. The third child showed AV malformation. The cystic lesions of the 14 children operated upon were proven histologically. The degree of accuracy in the present study was high. Conclusion: Precise perinatal management is warranted in order to determine according to the clinical relevance surgical intervention and to prevent complications after the first year of life. This is performed during the neonatal period for respiratory insufficient neonates and within the first year of life for clinically stable children. (orig.)

  8. A Wandering Abdominal Mass in a Neonate: An Enteric Duplication Cyst Mimicking an Ovarian Cyst.

    Iijima, Shigeo


    Enteric duplication cysts are rare congenital anomalies that are prenatally diagnosed through antenatal ultrasonography (US). In female patients, however, attention must be paid since these formations might be confused with ovarian cysts. Herein, we present a case of a low birth weight female infant with an enteric duplication cyst. A cystic lesion was detected in the right abdomen of the fetus on antenatal US and magnetic resonance imaging (MRI). Serial US and MRI examinations performed after birth showed a single cyst that wandered from side to side in the abdomen; the initial diagnosis was thought to be an ovarian cyst. During laparotomy, however, it was found to be an enteric duplication cyst with volvulus. To our knowledge, there has been no report of an enteric duplication cyst presenting as a wandering abdominal mass. Our experience indicates that early intervention is necessary for patients who have a wandering abdominal mass to avoid complications and urgent surgery, whether it is an ovarian cyst or an enteric duplication cyst.

  9. Isolated peritoneal hydatidosis clinically mimicking ovarian tumor: A rare case report

    Pradhan M Pagaro


    Full Text Available Hydatid cyst disease is rare and it is a parasitic infection where humans accidentally get infected by ingesting larval forms of parasite whereas, the definitive hosts are dog. The common sites of hydatid cyst are liver, lungs, spleen. Unusual sites of the hydatid cyst is reported in subcutaneous tissue of anterior abdominal wall, peritoneum. We report an unusual form of the primary hydatid cyst disease involving peritoneum in a 65-year-old female, presenting as swelling in the abdomen since 3 months. Sonography revealed a cystic mass and diagnosis of ovarian tumor was considered. The Cancer Antigen 125 (CA--125, an ovarian malignant marker was normal. Exploratory laprotomy was carried out. Cytological examination, gross, and the histopathological findings suggested the diagnosis of hydatid cyst disease involving only peritoneum. Primary isolated hydatidosis involving peritoneum is very rare and only few cases have been reported. Moreover, it mimics other tumors of the abdomen like in our case we considered it as an ovarian tumor.

  10. Diagnostic accuracy of ovarian cyst segmentation in B-mode ultrasound images

    Bibicu, Dorin; Moraru, Luminita; Stratulat (Visan), Mirela


    Cystic and polycystic ovary syndrome is an endocrine disorder affecting women in the fertile age. The Moore Neighbor Contour, Watershed Method, Active Contour Models, and a recent method based on Active Contour Model with Selective Binary and Gaussian Filtering Regularized Level Set (ACM&SBGFRLS) techniques were used in this paper to detect the border of the ovarian cyst from echography images. In order to analyze the efficiency of the segmentation an original computer aided software application developed in MATLAB was proposed. The results of the segmentation were compared and evaluated against the reference contour manually delineated by a sonography specialist. Both the accuracy and time complexity of the segmentation tasks are investigated. The Fréchet distance (FD) as a similarity measure between two curves and the area error rate (AER) parameter as the difference between the segmented areas are used as estimators of the segmentation accuracy. In this study, the most efficient methods for the segmentation of the ovarian were analyzed cyst. The research was carried out on a set of 34 ultrasound images of the ovarian cyst.

  12. The potential use of maturation in vitro of human oocytes in low responder patients.

    Requena, A; Neuspiller, F; Cobo, A C; Aragonés, M; Remohí, J; Simón, C; Pellicer, A


    To assess whether maturation in vitro of human oocytes (MIVHO) could be an alternative treatment in low responders to ovarian stimulation for in vitro fertilization (IVF). Prospective case-control study. Spontaneously ovulatory women who volunteered were included in our program of MIVHO at the Instituto Valenciano de Infertilidad. Rates of oocyte retrieval, in vitro maturation, fertilization, and development up to the blastocyst stage were studied. A significantly increased rate of oocyte retrieval was found when the pickup was performed before follicular selection. No differences were found when MIVHO was used in a low responder patient with an ovarian content of early antral follicles > 5 as compared to normal responders. MIVHO could be a successful choice in low responder patients with an acceptable number of early antral follicles. Oocyte retrieval should be performed before follicular selection in order to obtain more oocytes.

  13. Random-start controlled ovarian stimulation for emergency fertility preservation in a patient with myelodysplastic syndrome: a case report

    H. Cai


    Full Text Available This study reports a case of a gonadotropin-releasing hormone agonist trigger in a young female with myelodysplastic syndrome (MDS who underwent fertility preservation using random-start controlled ovarian stimulation. This method involves the stimulation of the ovary regardless of a patient's menstrual-cycle phase. A review of the related literature is also provided. A 17-year-old patient was diagnosed with MDS and required initiation of peripheral blood stem cell transplantation within a maximum of 3 weeks and was in the luteal phase of the menstrual cycle when the possibility of attempting preservation of fertility was presented to her. She opted for a random-start controlled ovarian stimulation with gonadotropins. With successful hemorrhagic prophylaxis, 17 oocytes were retrieved including 10 mature and 7 immature oocytes. Of the immature oocytes, 3 were successfully matured in vitro and a vitrification protocol was used to freeze the 13 mature oocytes.

  14. Analyses of the development and glycoproteins present in the ovarian follicles of Poecilia vivipara (Cyprinodontiformes, Poeciliidae

    Thiago L. Rocha


    Full Text Available The morphofunctional aspects of oogenesis of Poecilia vivipara were studied aiming to understand the reproductive biology and development of species with internal fertilization, particularly those belonging to the family Poeciliidae. The stages of gonadal maturation and follicular development were characterized using mesoscopic, histological, histochemical, and lectin cytochemical analyses. Through mesoscopic evaluation the ovarian development was classified in six phases of development: immature, in maturation I, in maturation II, mature I, mature II, and post-spawn. Based on microscopic examination of the ovaries, we identified the presence of oocytes types I and II during the previtellogenic phase and types III, IV, and V during the vitellogenic phase. As oogenesis proceeded the oocyte cytosol increased in volume and presented increased cytoplasmic granule accumulation, characterizing vitellogenesis. The zona radiata (ZR increased in thickness and complexity, and the follicular epithelium, which was initially thin and consisting of pavimentous cells, in type III oocytes exhibited cubic simple cells. The histochemical and cytochemical analyses revealed alterations in the composition of the molecular structures that form the ovarian follicle throughout the gonadal development. Our study demonstrated differences in the female reproductive system among fish species with internal and external fertilization and we suggest P. vivipara can be used as experimental model to test environmental toxicity.

  15. Recovery of fertility from adult ovarian tissue transplanted into week-old Japanese quail chicks.

    Liu, Jianan; Cheng, Kimberly M; Silversides, Frederick G


    Fertility of cryopreserved ovarian tissue from immature chickens and Japanese quail has been recovered by transplantation. This is of special importance for non-mammalian vertebrates in which cryopreservation and in vitro maturation of oocytes are challenging because their oogenesis is characterised by vitellogenesis. This study tested whether fertility of adult quail ovarian tissue could be recovered by transplantation. Ovaries were isolated from mature Japanese quail hens, trimmed, cut into 3- to 4-mm2 pieces and transplanted into ovariectomised, week-old chicks. Recipients were administered an immunosuppressant for two weeks. Ten of 12 recipients survived until sexual maturity and seven laid eggs, but all stopped laying by 17 weeks of age. The age at first egg of recipients laying eggs (75.7±4.2 days) was greater than that of untreated hens (51.8±1.7 days) and egg production of recipients during the laying period (21.7±5.7) was less than that of untreated hens (60.8±3.5). Recipients were paired with males from the WB line for test mating. Only two hens laid eggs during the test period but both produced 100% donor-derived offspring. This research demonstrated that the reproductive potential of ovarian tissue from adult quail hens can be restored by transplantation.

    Full Text Available An analysis of the use of minimally invasive interventions - laser-induced thermotherapy (LITT, ethanol destruction (ED under ultrasound guidance, a combination of these methods in the treatment of сystic-col- loidal nodes (CCN of thyroid nodules in 120 patients. ED carried out in 31 patients with cystic destruction of a site of more than 70%. Marked decrease in the average volume with 4.68 ± 2.25 cm3 to 1.15 ± 0.9 cm3. In 4 patients remained cystic cavity of small size, which required a combination of LITT (CombiLITT. Nine patients underwent LITT solid residue of more than 1 cm3. The average size of nodules within 6 months after the primary surgery was 0.9 ± 0.3 cm3. СombiLITT performed in 42 patients with cystic cavity from 20 to 70%. The volume of units decreased from 7.98 ± 4.56 to 1.87 ± 0.9 cm3. After 3 months, 11 patients with the size of a solid residue of more than 1 cm3 held LITT. All of them when viewed after 3 months observed decrease of more than 50%. LITT performed 23 patients with major nodes and cystic cavities less than 20% of the node. Marked decrease in the amount of nodes with 2.89 ± 1.25 cm3 to 1.42 ± 0.8 cm3. Retesting LITT took 2 patients. After 6 months, the average amount of units was 0.7 ± 0.2 cm3 LITT conducted in 24 patients with small cystic nodes to 1 cm3. Marked decrease in size from 0.69 ± 0.23 cm3 to 0.29 ± 0.12 cm3. Varied selection of minimally inva- sive treatment of CCN is effective and in most cases, to achieve reduction of the size of nodes.

  17. Response to ovarian stimulation in patients facing gonadotoxic therapy.

    Johnson, Lauren N C; Dillon, Katherine E; Sammel, Mary D; Efymow, Brenda L; Mainigi, Monica A; Dokras, Anuja; Gracia, Clarisa R


    Chemotherapy naïve patients undergoing embryo/oocyte banking for fertility preservation (FP) were assessed for response to ovarian stimulation. Fifty FP patients facing gonadotoxic therapy were matched by age, race, cycle number, date of stimulation and fertilization method to patients undergoing IVF for infertility or oocyte donation. There were no differences in baseline FSH, anti-Müllerian hormone, antral follicle count and total gonadotrophin dose. FP patients had more immature oocytes (2.2 versus 1.1; P=0.03) and lower fertilization rates per oocyte retrieved (52% versus 70%; P=0.002). There were no differences in numbers of oocytes retrieved, mature oocytes or fertilized embryos. Subgroup analysis revealed that FP patients taking letrozole required higher gonadotrophin doses (3077IU versus 2259IU; P=0.0477) and had more immature oocytes (3.4 versus 1.2; P=0.03) than matched controls. There were no differences in gonadotrophin dose or oocyte immaturity among FP patients not taking letrozole. Overall, chemotherapy naïve FP patients had similar ovarian reserve, response to stimulation and oocyte and embryo yield compared to controls. Patients who received letrozole required higher gonadotrophin doses and produced more immature oocytes, suggesting that response to ovarian stimulation may be impaired in patients with hormone-sensitive cancers receiving letrozole. With improvement in cancer survival rates, there has been a shift in attention toward management of long-term consequences of cancer therapy, including infertility. Many young women with cancer, particularly those who will be treated with chemotherapy, pursue fertility preservation (FP) strategies for the purpose of banking oocytes or embryos for future use. We examined patients with no prior exposure to chemotherapy who underwent IVF to freeze embryos or oocytes for FP. Fifty FP patients were identified and matched to healthy controls by age, race, cycle number, date of stimulation and fertilization

  18. The camp analogue, dbcAMP can stimulate rabbit reproductive functions: I. Effect on ovarian folliculogenesis, ovulation and embryo production

    Chrenek P.


    Full Text Available The aim of our study was to examine the influence of administration of N6,2’-dibutyryladenosine 3’5’-cyclic monophosphate (dbcAMP, a cAMP agonist, on ovarian folliculogenesis and atresia, as well as on reproductive efficiency in rabbits, whose ovarian cycle and ovulation was induced by gonadotropins. Ovarian cycle and ovulation of control rabbits were induced by 20 IU/kg PMSG followed by 35 IU/kg hCG administration. Experimental animals received PMSG and hCG together with dbcAMP (at 5, 25 or 50 μg/animal. After ovulation and insemination, the animals were sacrificed. Ovaries were weighted, histological sections of ovaries were prepared, and the presence of ovulated and not ovulated follicles and different stages of atresia was evaluated by light microscopy. The eggs were flushed from the oviducts after insemination and cultured up to blastocyst cell stage. Numbers of ovarian Corpora lutea, ovulated oocytes and oocyte-derived zygotes and embryos reaching hatched blastocyst stage were determined. Administration of dbcAMP (at doses 25 or 50 μg/animal, but not at 5 μg/animal was able to increase the proportion of follicles with cystic and luteinization-related atresia. Furthermore, dbcAMP (50 μg/animal, but not lower doses increased the ovarian mass, number of Corpora lutea, number of harvested oocytes, zygotes and embryos at blastocyst stage derived from these zygotes after culture. These data demonstrate that dbcAMP can stimulate rabbit ovarian follicle atresia, ovulation, oocyte, zygote and embryo yield and development. Furthermore, they confirm in the involvement of cyclic nucleotide-dependent intracellular mechanisms in the control of rabbit reproductive functions and potential practical usefulness of dbcAMP in improving animal reproduction and fertility.

    Full Text Available Ovarian cysts are common tumors among gynecological conditions. The case of a 46 years old woman who arrived at the Dr. Gustavo Aldereguía Lima General University Hospital in Cienfuegos, because of pain and swelling of the abdomen of a year of evolution is presented. The physical examination and ultrasound were performed and the patient was diagnosed with an ovarian dependant cystic mass. Laparotomy was performed and the left ovarian cyst was resected. In pathological and anatomical studies the diagnosis of an ovarian serous cystadenoma was confirmed.Los quistes de ovario son tumoraciones frecuentes en las afecciones ginecológicas. Se presenta el   caso de una paciente de 46 años de edad, que acudió al Hospital General Universitario Dr. Gustavo Aldereguía Lima, de Cienfuegos, refiriendo dolor y aumento de volumen del abdomen de un año de evolución. Se realizaron examenes físico y ultrasonográfico, mediante los que se le diagnosticó una masa quística dependiente de ovario. Se practicó laparotomía y se resecó un quiste de ovario izquierdo. En su estudio anatomopatológico se comprobó el diagnóstico de cistoadenoma seroso del ovario.

  20. Lack of correlation between pulmonary disease and cystic fibrosis transmembrane conductance regulator dysfunction in cystic fibrosis: a case report

    Cleveland Robert H


    Full Text Available Abstract Introduction Mutations in both alleles of the cystic fibrosis transmembrane conductance regulator gene result in the disease cystic fibrosis, which usually manifests as chronic sinopulmonary disease, pancreatic insufficiency, elevated sodium chloride loss in sweat, infertility among men due to agenesis of the vas deferens and other symptoms including liver disease. Case presentation We describe a pair of African-American brothers, aged 21 and 27, with cystic fibrosis. They were homozygous for a rare frameshift mutation in the cystic fibrosis transmembrane conductance regulator 3791delC, which would be expected to cause significant morbidity. Although 80% of cystic fibrosis patients are colonized with Pseudomonas aeruginosa by eight years of age, the older brother had no serum opsonic antibody titer to P. aeruginosa by age 13 and therefore would have failed to mount an effective antibody response to the alginate (mucoid polysaccharide capsule of P. aeruginosa. He was not colonized with P. aeruginosa until 24 years of age. Similarly, the younger brother was not colonized with P. aeruginosa until age 20 and had no significant lung disease. Conclusion Despite a prevailing idea in cystic fibrosis research that the amount of functional cystic fibrosis transmembrane conductance regulator predicts clinical status, our results indicated that respiratory disease severity in cystic fibrosis exhibits phenotypic heterogeneity. If this heterogeneity is, in part, genetic, it is most likely derived from genes outside the cystic fibrosis transmembrane conductance regulator locus.
