Gene expression analysis reveals an angiogenic profile in uterine leiomyoma pseudocapsule
In this study, quantitative RT–PCR analysis was performed on 18 matched PC, UL and UM specimens and results showed that the PC displays a specific gene expression profile. The low expression level of insulin-like growth factor (IGF-2), a fibroid specific marker, that we found in the PC and the UM when compared with the UL, clearly indicates that the PC is in structural continuity with the UM. However, the significant increase in endoglin expression level in PC with respect to the UL and UM indicates that an active neoangiogenesis is present in PC. Conversely, other angiogenic factors such as von Willebrand factor (vW...

Self-reported family history of leiomyoma: not a reliable marker of high risk
Conclusions: Many women may first learn about their family history of fibroids when discussing their own clinical diagnosis with family members. Such bias would invalidate self-reported family history as a predictor of fibroid risk. As new pharmacologic treatments for fibroids are developed, women at high risk of fibroids would benefit from early screening and pharmacologic treatment to delay development of large fibroids and reduce the need for invasive treatments. Self-reported family history is not useful for identifying high-risk women. (Source: Annals of Epidemiology)

Cotyledonoid dissecting leiomyoma treated by laparoscopic surgery: A case report
Abstract A cotyledonoid dissecting leiomyoma is categorized as a leiomyoma with an unusual growth pattern, which is characterized by remarkable extrauterine bulbous growth in continuity with a dissecting myometrial component. A 36‐year‐old patient was preoperatively diagnosed with a mature cystic teratoma of the left ovary, and according to MRI, the tumor protruded from the uterus into the right broad ligament and was 10 cm in diameter. She underwent laparoscopic surgery to resect ovarian teratoma and the tumor under the right broad ligament. The tumor was almost completely resected and diagnosed as a cotyledonoid di...

Congenital leiomyoma of the distal ileum associated with ileal atresia: A case report
Abstract: Association of distal ileal atresia with leiomyoma is a quite rare condition. Herein, we describe a newborn who underwent surgery for ileal atresia and was found to have leiomyoma on pathological examination in the atretic segment. The presence of leiomyoma may indicate a malformation during recanalization and could play a role in the etiology of intestinal atresia. Thus, some cases of atresia may be due to tumor (leiomyoma) in the bowel wall. (Source: Journal of Pediatric Surgery)

'I had to help my child!':: The role of emotions, risk, and trust in use of nasal decongestants in children
Recent studies suggest that a number of common cold medicines, including nasal decongestants are not suitable for small children. In Latvia nasal decongestants are primarily over-the-counter (OTC) medicines, and patient information leaflets generally permit use of these medicines for small children. The previous studies in Latvia investigating the use of medicines in cases of common cold demonstrated extensive use of decongestants in children less than six years of age, marking a necessity for more profound research. As a result a qualitative study was implemented in 2011 to identify sources of information that offer advic...

Ischemic Stroke Related to Severe Iron-Deficiency Anemia in Adults May Benefit from Blood Transfusion (P01.232)
CONCLUSIONS: Prevalence of IDA is 1-20%; it is 3.9% in our AIS population and is often related to untreated uterine bleeding. As described in the pediatric population, severe IDA may be an underlying mechanism of ischemic stroke in adults, therefore, efforts must be undertaken to identify and treat the cause of the anemia. While patients with AIS and severe IDA may receive TPA, blood transfusion may be considered as an adjuvant therapy.Supported by: SPOTRIAS P50 NS044227 & NIH Training Grant 5T 32NS0077412-12.Disclosure: Dr. Choi has nothing to disclose.

Progesterone Action in Endometrial Cancer, Endometriosis, Uterine Fibroids, and Breast Cancer.
Abstract Progesterone receptor (PR) mediates the actions of the ovarian steroid progesterone, which together with estradiol regulates gonadotropin secretion, prepares the endometrium for implantation, maintains pregnancy, and differentiates breast tissue. Separation of estrogen and progesterone actions in hormone-responsive tissues remains a challenge. Pathologies of the uterus and breast, including endometrial cancer, endometriosis, uterine fibroids, and breast cancer, are highly associated with estrogen, considered to be the mitogenic factor. Emerging evidence supports distinct roles of progesterone and its influ...

Adrenal Nodular Hyperplasia in Hereditary Leiomyomatosis and Renal Cell Cancer
Conclusions: Unilateral and bilateral adrenal nodular hyperplasia was detected in a subset of patients with hereditary leiomyomatosis and renal cell carcinoma. A functional endocrine evaluation is recommended when an adrenal lesion is discovered. Imaging frequently reveals lesions that are not typical of adenomas and positron emission tomography may be positive. To date no patient has had adrenal malignancy, and active surveillance of hereditary leiomyomatosis and renal cell carcinoma adrenal nodules appears justified. (Source: The Journal of Urology)

We report here a case of a 53-year-old woman who presented to us with multiple painful nodules over different parts of her body. Based on the histopathological examination, imaging, and past medical records, a diagnosis of Reed's syndrome was made. Three of her sisters had similar disease. Subsequently, it was found that a total of nine members of their family in two successive generations were affected with cutaneous leiomyomas. The present case series has been reported for its interesting clinical presentations and rarity. (Source: Indian Journal of Dermatology, Venereology and Leprology)

Polymorphism of catechol-o-methyltransferase and uterine leiomyoma.
Abstract Uterine leiomyoma (ULM) is the most common gynecological benign tumor that is affecting around 20-50 % of women over the age of 30. Although its molecular pathogenesis is still unknown, ULM has a multifactorial etiology determined by both genetics and environmental factors. The present study was designed to find out whether Val158Met polymorphism in the catechol-o-methyltransferase (COMT) gene is associated with the risk of ULM. We analyzed COMT Val158Met polymorphism in 105 ULMs patients and 105 healthy subjects using a polymerase chain reaction-based restriction fragment length polymorphism assay. We fo...

Pulmonary benign metastasizing leiomyoma: a case report and review of the literature
Pulmonary benign metastasizing leiomyoma characterized by the growth of uterine leiomyoma in the lung is a very rare disease. We herein report the case of a 46-year-old asymptomatic woman who underwent a total abdominal hysterectomy for her multiple uterine leiomyomas 5 years ago, with the presence of multiple shadows in her chest roentgenogram during the regular check-up. Chest computerized tomography (CT) showed multiple solitary nodules in both lungs. Video-assisted thoracoscopic surgery with a wedge resection of the lesion was performed. Histopathologically, the pulmonary nodule was composed of benign smooth muscle cel...

Pulmonary sclerosing hemangioma presenting with
dense spindle stroma cells: a potential diagnostic
Pulmonary sclerosing hemangioma (PSH) is an uncommon pulmonary tumor. Histologically,PSH typically consists of two types of cells, surface cuboidal cells and polygonal cells, fourarchitectural patterns including papillary, sclerotic, solid, and hemorrhagic. Herein, wepresent a case of PSH in a 59-year-old Chinese female. The tumor was predominantlycomposed of solid area presenting with diffuse spindle cells rather than polygonal cells.Focally, classical papillary and sclerotic area could be seen. Immunohistochemical stainingshowed that the spindle cells were positive for TTF-1, EMA, Actin(SM) and Vimentin, andnegative for ...
