Objective: Prostatic diseases (benign and malignant) are broadly widespread in the world. Benign prostatic hyperplasia is a chronic entity reflected by enlarged prostatic tissue, triggering inferior urinary tract complaints. On the other hand, prostate cancer, is the second most common cancer in men and the fourth utmost commonly happening cancer generally. OCT4 referred to as octamer binding transcription factor 4, also recognized as POU5F1 (POU domain class 5 transcription factor 1), is a protein that in humans is coded by the POU5F1 gene. This protein is analytically elaborate in the self-renewal of undifferentiated embryonic stem cells. As such, our work is designed to evaluate the immunohistochemical examination of OCT4 expression in the prostatic epithelium in cases of benign prostatic hyperplasia (BPH) and in the epithelium of prostatic adenocarcinoma microenvironment (NPCA). Patients and Methods: The prostate samples were acquired from 50 BPH patients, and 50 prostatic cancer patients. The samples were managed for immunohistochemical examination of OCT4 expression. Results: Statistical analysis revealed significant difference in the staining percentage between the BPH and NPCA group (P-value=0.009), and there was significant staining expression of OCT4 in NPCA group as compared to BPH group (P-value=0.000). Also, there was significant elevation of the total score of OCT4 in NPCA group (P-value=0.036) as compared with BPH group. Conclusions: OCT4 is over expressed in normal tissue around prostatic carcinoma as compared to benign tissue in BPH, and thus OCT4 can be used as a stem cell marker for prostatic tissue tuomorigenicity.

Breast cancer describes several subtypes of cancer of the breast that differs in clinical presentation, which reveals different gene expression and different molecular characteristics.

Objective The association between Helicobacter pylori and hypertension is unclear. Herein, we aimed to investigate the association between H. pylori and hypertension among adults in Sudan. Methods We conducted a community-based case–control study (175 participants in each arm) in the Wad Hamid district in northern Sudan. Cases comprised adults with hypertension and controls were non-hypertensive adults. We assessed participants' data using a questionnaire. We also conducted rapid H. pylori antibody tests and binary and linear regression analyses. Results Multivariable logistic regression revealed age (adjusted odds ratio [AOR] 1.05, 95% confidence interval [CI] 1.03–1.07), female sex (AOR 5.50, 95% CI 2.36–12.80), and body mass index (AOR 1.12, 95% CI 1.07–1.17) were significantly associated with hypertension. Moreover, compared with controls, a significantly higher number of patients with hypertension were positive for H. pylori (82/175, 46.9% vs. 46/175, 26.3%). H. pylori seropositivity was associated with systolic blood pressure (coefficient 3.811), diastolic blood pressure (coefficient 3.492), mean blood pressure (coefficient 3.599), and hypertension (AOR 3.15, 95% CI 1.82–5.46). Conclusion Our study revealed a significant positive association between H. pylori seropositivity and hypertension. This finding supports literature recommending the eradication of H. pylori to prevent hypertension and its complications.

Background: Male infertility is a common problem and needs a minimally invasive method to arrive at the appropriate diagnosis. Alternative to open testicular biopsy the fine needle aspiration cytology (FNAC) of the testis is being increasingly used as a minimally invasive method of evaluating testicular function. Aim: To determine the causes of azoospermia and evaluate the efficacy of FNAC as compared to open testicular biopsy in evaluating azoosparmic men by correlating diagnosis from testis FNAC with biopsy histology. Patients and Methods: We prospectively studied 67 consecutive infertile patients who referred to andrology department of Al-Yarmouk Teaching hospital, Baghdad, Iraq between (January 2010-January 2014). All patients were azoospermic. They underwent bilateral testicular fine needle aspiration for cytological evaluation as well as bilateral testicular biopsy for histopathological correlation. Results: The morphological diagnosis revealed normal spermatogenesis in 12 patients (17.9%), hyposparmatogenesis in 4 (5.9%), spermatogenic arrest in 39 (58.2%), Sertoli cell only in 7 (10.4%), and complete tubular hyalinization in 5 patients (7.4%). Good correlation between the 2 methods was found in 120 (91.6%) testes which was identical in the right and left testis. Discrepancies between cytology and histology were mainly the result of insufficient and scanty smears. Conclusion: Testicular FNAC is a simple and minimally invasive alternative method to open testicular biopsy in the investigation and assessment of patients with azoospermia.
