Primary hyperoxaluria (PH) is a rare inborn error in the pathway of glyoxylate metabolism which causes excessive oxalate production. The disease is characterized by widespread deposition of calcium oxalate (oxalosis) in multiple organs. Urinary tract including renal parenchyma is the initial site of deposition followed by extrarenal organs such as bone marrow. This case report introduces a 54-year-old woman with end stage renal disease presenting with debilitating fatigue and pancytopenia. The remarkable point in her past medical history was recurrent episodes of nephrolithiasis, urolithiasis, and urinary tract infection since the age of 5 years and resultant end stage renal disease in adulthood in the absence of appropriate medical evaluation and treatment. She had an unsuccessful renal transplantation with transplant failure. The patient underwent bone marrow biopsy for evaluation of pancytopenia. Microscopic study of bone marrow biopsy led to the diagnosis of primary hyperoxaluria.

The aim of this study is the assessment of relationship between E-cadherin expression and routine prognostic biomarkers as well as grading and lymph node status in breast invasive ductal carcinomas. . The associations between co-expression of E-cadherin and other biomarkers on one hand and grading, proliferating index and lymph node status on the other have also been evaluated. To evaluate the correlation of E-cadherin expression and routine immunohistochemistry panel in breast invasive ductal carcinoma. 108 formalin-fixed and paraffin-embedded breast cancer specimens (of invasive ductal carcinoma "NOS" type) from the pathology archive of Alzahra hospital(Isfahan, Iran) which had been studied for expression of routine molecular biomarkers were selected. E-cadherin expression was detected by immunohistochemistry. Stained se...

For this systematic review, we explored 2183 published papers about herbal drugs interactions from November 1967 to August 2014, fulfilling eligibility criteria by searching in some databases such as Web of Science, Medline, Scopus, Embase, Cinahl, and the Cochrane database. The main keywords used for searching included: herbal medicine, herbs, statin, lipid, and herb-drug interaction. Among published articles about herb-drug interactions, 185 papers met the initial search criteria and among them, 92 papers were potentially retrievable including a description of 17 herbs and medicinal plants. In first step and by reviewing all published manuscripts on beneficial effects o...

The median nerve is most commonly affected. The lesion is characterized by a soft slowly growing mass surrounding and infiltrating major nerves and their branches. It may cause symptoms of compression neuropathy and is associated with macrodactyly in one third of cases. Here, we present a case of neural fibrolipoma in the ankle region and dorsum of foot of a young man arising from superficial peroneal nerve. KEY WORDS: Fibrolipomatous hamartoma, neural fibrolipoma, macrodactyly, superficial peroneal nerve.

If the SLN is negative for metastatic disease, then other nodes are expected to be disease-free. SLN techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. This study aims to evaluate our technique in SLN mapping in early stage endometrial and cervical cancers. We scheduled a cross-sectional pilot study for patients undergoing staging surgery for endometrial and cervical cancer from November 2012 to February 2014 in Beheshti and Sadoughi Hospitals. Our SLN mapping technique included 1 h preoperative or intraoperative injection of 4 ml of 1% methylene blue dye in the tumor site. At the time of surgery, blue lymph nodes were removed and labeled as SLNs. Then systematic lymph node dissection was completed, and all of the nodes were sent for pathologic examination concerning metastatic ...

The present systematic review aimed to evaluate the safety of herbal medicines and also to assess drug interaction in herbal therapy in treating hyperlipidemia. The international research databases including MEDLINE; Google scholar, Web of Science SciVerse Scopus (SCOPUS); EBSCO Academic Search; Cochrane Central Register of Controlled Trials (CENTRAL); and a Chinese database (China Network Knowledge Infrastructure [CNKI]) were searched from their respective inceptions up to September 2014 with the search terms of "hyperlipidemia", "herbal medicine", "medicine traditional", "extract plant", "Traditional Medicine" and "Chinese Herbal Medicine" without narrowing or limiting search elements. A total of 85 randomized clinical trials (RCTs) studies were finally...

On the basis of the extent of sex cord differentiation, uterine stromal tumors with this kind of differentiation have been classified into 2 subgroups of endometrial stromal tumor with sex cord-like elements and uterine tumors resembling ovarian sex cord tumor. When extensive, this differentiation has been accompanied with indolent clinical behavior and rather good prognosis in most cases. Sex cord differentiation has been rarely observed in uterine mullerian adenosarcoma. Only 3 cases of such occurrence have been reported in the English literature. Herein, we report a case of uterine mullerian adenosarcoma extensively overgrown by uterine tumor resembling ovarian sex cord tumor in a young woman. The presence of an ovarian sex cord tumor component has been confirmed by immunohistochemistry. To the best of our knowledge, this is the second report of such a case in the English literature.

Myoepithelial and luminal epithelia can be distinguished by their different cytokeratin expression patterns. The aim of this study is to evaluate the expression of some prognostic biomarkers (ER, PR and HER2), as well as histological grading and lymph node status in cytokeratin-based groups of breast cancer. To evaluate the correlation between expression of basal and luminal markers and hormonal receptors, HER2/neu, age, grade and lymph node status in breast-invasive ductal carcinoma. Sixty-seven formalin-fixed and paraffin-embedded breast cancer specimens (of invasive ductal carcinoma, 'NOS' type) which had already been studied for ER, PR and HER2/neu were selected. Data concerning age, tumor grade and lymph node status were also obtained from archives. Expression of basal (CK5/6) and luminal (CK7) cytokeratins was detected by immunohistochemistry. Stained sections were classified according to the intensity of staining and the percentage of stained cells. We categorized the cases into 3 distinct phenotype groups: pure luminal, basal phenotype and null. Pure basal, mixed basal and luminal groups were classified as expressing a basal phenotype. There was a significant difference in the ER and/or PR expression between those 3 groups and a significant association between ER and/or PR negativity and basal phenotype expression. There was no significant difference in HER2/neu expression, age of the patients, tumor grade and lymph node status between the 3 cytokeratin-based groups and no significant association between lymph node status and basal phenotype expression. We found that to gain a real association between basal phenotype and prognostic markers, we should use a cocktail or a panel of different biomarkers to correctly determine basal-like phenotype of breast cancers. This approach guarantees more concordance with gene expression-based studies.

CCND1, the oncogene encoding cyclin D1, is amplified in a substantial proportion of human cancers. Although cyclin D1 overexpression has been reported in up to 50% of human breast cancers, its prognostic impact on breast carcinoma is still controversial. In this cross-sectional investigation, 89 patients with breast invasive ductal carcinoma enrolled in the study. Tumor tissue samples were stained immunohistochemically for cyclin D1. The marker was semiquantitatively scored using the Allred scoring method and its relationship with ER, PR, and HER2-neu status as well as age, tumor grade and stage was then determined. Cyclin D1 was strong (S), intermediate (I), weak (W), and negative (N) in 19.1%, 44.9%, 14.6%, and 21.3% of the cases, respectively. Estrogen receptor (ER), progesterone receptor (PR), and HER2- neu were positive in 60.7%, 58.4%, and 36% of the cases, respectively...
