Ductal plate malformations are a heterogenous group of congenital fibrocystic liver diseases resulting from insult to the ductal plate at various stages of embryogenesis. As a result various biliary malformations, cysts, hamartomas and congenital hepatic fibrosis may be seen. We present a radiological pictorial of ductal plate malformations, accurate diagnosis of which is important for clinical management.

Autosomal recessive polycystic kidney disease (ARPKD) and other hepatorenal fibrocystic diseases (HRFD) are relatively rare recessive disorders that constitute an important set of childhood nephropathies. Little is known about fundamental pathogenesis, and advances toward clinical trials will require well-characterized patient cohorts and the development of predictive and prognostic biomarkers. Such studies in rare diseases require greater collaboration than the efforts in common diseases where large patient repositories can be built at a single site...

Polycystic kidney disease (PKD) involves progressive hepatorenal cyst expansion and fibrosis, frequently leading to end-stage renal disease. Increased vasopressin and cAMP signaling, dysregulated calcium homeostasis, and hypertension play major roles in PKD progression. The guanylyl cyclase A agonist, B-type natriuretic peptide (BNP), stimulates cGMP and shows anti-fibrotic, anti-hypertensive, and vasopressin-suppressive effects, potentially counteracting PKD pathogenesis. Here, we assessed the impacts of guanylyl cyclase A activation on PKD progression in a rat model of PKD...

Sclerosing polycystic adenosis (SPA) is a rare benign neoplasm of the salivary gland which resembles the fibrocystic disease of the breast clinically as well as morphologically. This entity has varied morphological presentation on fine needle aspiration. Only a few case reports and occasional case series are found in the literature describing its cytology. Here we are presenting a case of SPA in the parotid gland in a 13-year-old male patient who presented with a slow growing infra-auricular mass since one year without any other symptoms...

This paper proposes a texture analysis technique that can effectively classify different types of human breast tissue imaged by Optical Coherence Microscopy (OCM). OCM is an emerging imaging modality for rapid tissue screening and has the potential to provide high resolution microscopic images that approach those of histology. OCM images, acquired without tissue staining, however, pose unique challenges to image analysis and pattern classification. We examined multiple types of texture features and found Local Binary Pattern (LBP) features to perform better in classifying tissues imaged by OCM...

PURPOSE OF REVIEW: To review disorders that are associated with renal cystic disease during prenatal life and to highlight the strong association between renal cystic disease and ciliopathies. RECENT FINDINGS: There are numerous causative genes for ciliopathies that can present with cystic kidney disease. In the group of single gene ciliopathies, autosomal dominant polycystic kidney disease is by far the most prevalent one. Other examples are autosomal recessive polycystic kidney disease, nephronophthisis, Bardet-Biedl syndrome, Meckel-Gruber syndrome, Joubert syndrome and related disorders as well as X-linked orofaciodigital syndrome type 1, respectively...

Primary hyperparathyroidism (PHPT) is a disease involving a broad range of alterations of calcium homeostasis, sustained by parathyroid hormone (PTH) levels that are clearly abnormal. The anomalies directly associated with hyperparathyroidism are nephrolithiasis and fibrocystic bone disease. Since PHPT resolves when abnormal parathyroid tissue is removed, surgery is clearly the only definitive approach to this type of hyperparathyroidism. However there are large subgroups of patients for whom medical therapy should be considered instead of surgery...

The concept of end-stage lung disease suggests a final common pathway for most diffuse parenchymal lung diseases. In accordance with this concept, end-stage disease is characterized radiographically and pathologically by the presence of extensive honeycombing. However, sequential computed tomographic (CT) scans obtained from patients with chronic diffuse lung disease evolve over time to show various advanced lung disease patterns other than honeycombing. In addition, several radiographically distinct honeycomb patterns, including microcystic, macrocystic, mixed, and combined emphysema and honeycombing, differentiate one advanced lung disease from another...

Clinical trials have revealed that molecular iodine (I2) has beneficial effects in fibrocystic breast disease and in cyclic mastalgia. Likewise, povidone-iodine (PVP-I), which is widely used in clinical practice as an antiseptic agent following tumour surgery, has been demonstrated to have cytotoxic effects on colon cancer and ascites tumour cells. Our previous study indicated that the growth of breast cancer and seven other human malignant cell lines was variably diminished by I2 and iodolactones. With the intention of developing an iodine-based anticancer therapy, the present investigations extended these studies by comparing the cytotoxic capacities of I2, potassium iodide (KJ), PVP-I and Lugol's solution on various human carcinoma cell lines...

BACKGROUND: Increasing serum levels of uric acid (SUA) after menopause in women brought up a hypothesis that estrogenic effect may protectively regulate SUA. Estrogenic effect is a major etiology of uterine fibroids and fibrocystic breast disease. The study aimed to explore SUA among patients suffering from these diseases to enhance the hypothesis. METHODS: Overall, 1349 female participants were selected into three cases: Case I having uterine fibroids (n=568), Case II having fibrocycstic breast disease (n=608) and Case III having uterine fibroids combining with fibrocycstic breast disease (n=173); 4206 participants without these diseases were selected as controls...

Benzyl isothiocyanate (BITC) is a highly promising phytochemical abundant in cruciferous vegetables with preclinical evidence of in vivo efficacy against breast cancer in xenograft and transgenic mouse models. Mammary cancer chemoprevention by BITC is associated with apoptotic cell death but the underlying mechanism is not fully understood. Herein, we demonstrate for the first time that altered mitochondrial dynamics is an early and critical event in BITC-induced apoptosis in breast cancer cells. Exposure of MCF-7 and MDA-MB-231 cells to plasma achievable doses of BITC resulted in rapid collapse of mitochondrial filamentous network...

The present study is the first to report inhibition of breast cancer cell growth in vitro and in vivo and suppression of self-renewal of breast cancer stem cells (bCSC) by a pine bark component (leelamine). Except for a few recent publications in melanoma, anticancer pharmacology of this interesting phytochemical is largely elusive. Leelamine (LLM) dose-dependently inhibited viability of MDA-MB-231 (triple-negative), MCF-7 (estrogen receptor-positive), and SUM159 (triple-negative) human breast cancer cells in association with apoptotic cell death induction...

BACKGROUND: Ectopic breast tissue, which includes both supernumerary breast and aberrant breast tissue, is the most common congenital breast abnormality. Ectopic breast cancers are rare neoplasms that occur in 0.3% to 0.6% of all cases of breast cancer. PATIENTS AND METHODS: We retrospectively report, using a large series of breast abnormalities diagnosed and treated, our clinical experience on the management of the ectopic breast cancer. In 2 decades, we observed 327 (2...

It is known that benign breast tissue exhibit relatively low angiogenic capacity. Activation of angiogenesis in mammary pre-malignant lesions could be associated with disease progression and high risk of transformation into the breast cancer. However, insight into the underlying molecular mechanisms involved in angiogenesis regulation in non-cancerous breast pathologies is still poorly defined. The purpose of the present study was to determine levels of plasminogen and its proteolytic fragments (angiostatins) in mammary dysplasia (mastopathy and breast cyst) and benign neoplasms (fibroadenomas)...

With regard to different types of malignancies, thymidine kinase 1 (TK1) is a useful prognostic marker in clinical oncology, both as a serum proliferation marker and in immunohistochemistry. The present study investigated the use of serum TK1 protein (STK1p) for the identification of multiple proliferating diseases linked to the risk of developing cancer, by following one patient during the period of 2003-2014. The patient presented with adenomatous polyps in the stomach in 2003, follicular cervicitis in 2007 and hyperplasia of the breast/fibrocystic breasts in 2010...

Fibroadenomas are a type of benign tumor that occur in young women below the age of 35 years old. The tumors are the second most common type of tumor after fibrocystic disease. The chance of carcinoma arising in a fibroadenoma is extremely low. To date, <130 such cases have been reported. Previous studies have reported that fibroadenomas can evolve into a number of different types of malignancy. The present study is the first to describe a case of bilateral primary breast cancer with a unilateral invasive ductal carcinoma within a fibroadenoma...
