Use of immunohistochemistry and silver in situ hybridization (Sish) in evaluation of human epidermal growth factor receptor2 (HER2/neu) status in Iraqi patients with breast cancer
...Show More Authors

Breast cancer is the commonest cause of cancer related death in women worldwide. Amplification or over-expression of the ERBB2 (HER/neu) gene occurs in approximately 15-30% of breast cancer cases and it is strongly associated with an increased disease recurrence and a poor prognosis. Determination of HER2/neu status is crucial in the treatment plan as that positive cases will respond to trastuzumab therapy. It has been used to test for HER2/neu by immunohistochemistry as a first step and then to study only the equivocal positive cases (score 2+) by in situ hybridization technique. The aim of our study is to compare between immunohistochemistry and silver in situ hybridization (SISH) in assessment of human epidermal growth factor (HER2/neu) receptors status among breast cancer patients. A cross-sectional study was conducted at The Medical City in Baghdad, from October 2016 to April 2017, where formalin fixed, paraffin embedded tumor tissue from 52 female patients (aged 33 to 71 years) with the diagnosis of breast cancer have been included in this study for the evaluation of human epidermal growth factor (HER2/neu) protein overexpression and gene amplification by immunohistochemistry and silver in situ hybridization (SISH) method respectively. Base line data about patients were obtained from their hospital records. The distribution of human epidermal growth factor (HER2/neu) protein overexpression by immunohistochemistry showed that the (+2) score/equivocally positive were seen in 24 cases, which comprise the largest number of cases in this study (46.15%). Ten cases (19.23%) for each of scores 0/negative and +1/negative were present, while (+3) score/positive was the smallest group with only 8 cases (15.38% of cases). All results of SISH were negative in the category of (0 score/negative). In the contrary, all the 8 cases in (+3 score/positive) category were showing positive SISH results. Category (+1 score/negative) HER2 showed two cases (20%) with a positive SISH result, while that of (+2 score/equivocal positive) showed 8 positive cases (about 33.33%). For the detection of HER2/neu protein overexpression and gene amplification, immunohistochemistry (IHC) and in-situ hybridization (ISH) are the recommended techniques, with high concordance between the two techniques, however; performance of silver in situ hybridization in assessment of HER2/neu gene status in all cases of invasive breast carcinoma is recommended as significant number of negative cases by immunohistochemistry showed positive amplification by in situ hybridization and can be treated with anti-HER2 targeted treatments.

ABSTRACTBackground Subclinical hypothyroidism is mild thyroid hormone deficiency, defined by elevation of serum thyroid-stimulating hormone concentration despite a normal free T3, free T4 level, can be distinguished by clinical and circumstantial observations from other conditions that cause this constellation of laboratory findings. The aim is to find the prevalence, anthropologic, and metabolic changes associate subclinical hypothyroidism(SH) in adult patients presented to obesity research and therapy unit (ORTU Objective: To find the prevalence of subclinical hypothyroidism (SH) in adult obese patients presented to obesity research and therapy unit (ORTU) in AL-Kindy College of medicine and to describe the anthropologic and metabolic

Effect of chemotherapy on oral health status and salivary alkaline phosphatase among leukemic patients
...Show More Authors

Background: Leukemia is a broad term given to a group of malignant diseases characterized by diffuse replacement of bone marrow with proliferating leukocyte precursors. Chemotherapy has been increasingly used to treat malignant conditions. The systemic sequelae as a result of these immunosuppressive techniques induce many oral and dental complications. This study was conducted to evaluate the effect of chemotherapy on oral health status and activity of salivary alkaline phosphates enzyme in patients with acute lymphocytic leukemia. Materials and methods: The study groups included 28 patients with acute lymphocytic leukemia; they were under chemotherapy, aged 20-25 year old. The control group includes healthy subjects matching with study

Evaluation to the level of some inflammatory markers in hypothyroid insulin resistant patients
...Show More Authors

Hypothyroidism is a condition in which thyroid hormones levels decreased in the blood. These hormones are necessary for energy production and body viability. In many occasions this condition is accompanied or followed by different metabolic disorders. The current study is conducted in the "Specialized center for endocrinology and diabetes" and carried on 70 hypothyroid patients and 60 randomly chosen individuals with normal thyroid function .Both groups were submitted to laboratory tests to evaluate thyroid function (T3,T4.TSH). The study involved evaluation of the relationship between hypothyroidism and insulin resistance (IR) . Health problem related to many diseases , became common lately. Insulin resistance diagnosed through

A COMPARATIVE STUDY OF RETN GENE 3สน-UNTRANSLATED REGION POLYMORPHISM RS1862513 IN IRAQI PATIENTS WITH TYPE 1 AND TYPE 2 DIABETES MELLITUS
...Show More Authors

Both type 1 diabetes and type 2 diabetes have a genetic component, with over 60 chromosomal regions related to type 1 diabetes and over 200 connected with type 2 diabetes at significant genome-wide levels. Numerous single nucleotide polymorphisms in the RETN gene and genetic variables can account for up to 70% of the variations in circulating resistin levels. The RETN polymorphism has been linked in numerous studies to obesity, insulin sensitivity, type 2 diabetes, and cerebrovascular illness. Our objective is to compare this RETN gene 3ʹ-untranslated region polymorphism in type 1 diabetes and type 2 diabetes Iraqi patients. We choose 51 type 1 diabetes and 52 type 2 diabetes patients against 50 healthy subjects (control group) to investig
