BACKGROUND Human epidermal growth factor receptor-2 HER2 / neu, is a trans membrane tyrosine kinase receptor of epidermal growth factor receptor (EGFR) family and is involved in the pathogenesis of urinary bladder cancer. In this study we attempted to evaluate the HER2 / neu expression in urothelial carcinoma of bladder and its association with tumour grading. METHODS This was a cross sectional study with a sample size of 75. Routine 4 micrometre thick sections of formalin fixed paraffin embedded tissue blocks stained with haematoxylin & eosin were reviewed. Tumour grade was determined by using the World Health Organization (WHO) / International Society of Urological Pathologist criteria (ISUP). Immunohistochemistry was done by using HER2 / neu monoclonal antibody and its expression were observed. The membrane staining intensity and pattern were studied and scored. RESULTS In our study 75 cases of urothelial carcinoma were studied, of which 49 cases were papillary urothelial carcinoma low grade, 26 cases were papillary urothelial carcinoma high grade. Among these, 19 cases were infiltrating urothelial carcinoma. HER2 / neu positivity were observed in 27 (36 %) cases and overexpression in 8 (10 %) cases. Low grade urothelial carcinoma showed HER2 / neu positivity in 11 (22 %) cases and overexpression in 1 (2 %) case. High grade urothelial carcinoma showed HER2 / neu positivity in 16 (64 %) cases, among which 7 (28 %) cases showed overexpression. HER2 / neu positivity was seen in 13 (68 %) cases of infiltrating urothelial carcinoma with 4 (21 %) cases showing overexpression. A statistically significant difference in HER2 / neu expression was noted in high grade and invasive urothelial carcinoma compared to low grade and non-invasive urothelial carcinoma. CONCLUSIONS Urothelial carcinomas show overexpression of HER2 / neu and this over expression increases with increasing grade of tumour and muscle invasiveness.

Abstract Background: Meningioma is the most common intracranial tumor in adults. In addition to the extent of tumor surgical resection and WHO grade, angiogenesis is a prognostic factor that is influenced by MMP-2. Our study examined the association of these prognostic factors with MMP-2 expression in meningioma. Methods: A cross-sectional study of patients diagnosed with meningioma between January 2008 and December 2017 was conducted. All samples were re-reviewed and subjected to immunohistochemical staining for Ki67, MMP-2, and CD34. Pearson’s chi-squared test and Fisher’s exact test were used to examine the association of MMP-2 expression with the WHO grade and microvascular density (MVD). Results: The study included 99 patients aged 23–75. Most patients were female (73.7%). This study included 85 cases of low-grade meningioma (grade I) and 14 cases of high-grade meningioma (grade II, 11; grade III, 3). The most common subtypes were meningothelial, transitional, and fibroblastic. In total, 62 of 85 patients with low-grade meningioma and 10 of 14 patients with high-grade meningioma exhibited high MMP-2 expression, and the difference in the rates between the groups was not significant. Most patients in this study displayed MVD scores of 1+ (54/99) and 2+ (33/99). Of the 54 patients with an MVD score of 1+, 42 exhibited high MMP-2 expression. MMP-2 was expressed by all patients with meningioma. Conclusion: In the future, more samples are required, in high-grade tumors, to prevent bias, and more specific immunohistochemical markers should be used to evaluate angiogenesis.

Background: Urothelial carcinoma is the common carcinoma of urothelium. Its incidence is high in developed countries but itsoccurrence is increasing in developing countries like Pakistan with mortality rate of 3.8/100,000 in males and 1/100,000 in females.HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family.Amplification or over-expression ofthis oncogene has been shown to play an important role in the development and progression urothelial carcinoma.Objective: To evaluate the relationship between HER2/NEU expression and grades of urothelial carcinoma bladderMaterial and Methods: This was a cross-sectional descriptive study for the period of six months from January to June, 2017conducted at Pathology section Rehman Medical Institute Peshawar. After approval from university Ethical board 63 cases wereselected by purposive sampling.The Tissue samples from diagnosed cases of urothelial carcinoma of urinary bladder were included.Cases of urothelial carcinoma from other sites were excluded. Paraffin embedded tissue blocks were cut and sections stained byH&E to evaluate histopathological features and tumor grades. Immunohistochemical expression of HER2 was determinedapplying standard techniques of immunohistochemistry.Results: Out of total 63 cases, 47 were males and 16 were female with a mean age of 60.7 years (range 14-90 years). There were38 High grade, 23 Low grade and 2 cases of PUNLMP. 36 cases were positive for HER2 expression in which 26(72.2%) were Highgrade, 9(25%) of Low grade and 1(2.7%) of PUNLMP. High grade was more common in HER2 positive cases and this relationshipwas significant (p<.05). Among positive 36 cases, 19 cases of +3 score were High grade, 05 in Low grade and 01 in PUNLMP whilescore 2+ was in 07 cases of High grade and 04 were in Low grade. The relationship of HER2 score was not significantly related tograde of tumor (p>.05)Conclusion: HER2 is highly expressed in high grades of urothelial carcinoma bladder and this relationship between HER2expression and tumor grades is statistically significant.Keywords: HER2, Urothelial carcinoma, Grades, Immunohistochemistry

Hypertension is a major public health problem all over the world. The incidence of hypertension is increasing year after year and the prevalence of hypertension is increasing day by day due to increased life expectancy and aging population and their sedentary lifestyle. Hypertension is known to cause microvascular changes and increased cardiovascular risk from it. Microalbuminuria possibly reflects a state of increased renal endothelial permeability and is an easily measured marker of rather diffuse endothelial dysfunction, low grade inflammation and vascular disease burden2. Microalbuminuria has been determined as an important prognostic indicator and has been reported to be associated with increased cardiovascular risk and progressive renal damage. Reliable data on the prevalence of microalbuminuria in the general population and its association with cardiovascular risk factors is limited. Till now, there is little data available regarding screening and early treatment of hypertensive patients with microalbuminuria, as in the case of microalbuminuric non diabetic subjects. With these perspective this cross sectional study of microalbuminuria in non-diabetic hypertensive patients was undertaken to study prevalence of microalbuminuria in Non Diabetic hypertensive patients. Objectives: To determine the prevalence of microalbuminuria in non-diabetic hypertensive patients and to correlate the presence of microalbuminuria with the patients of different clinical profiles. Materials and Methods: This was observational, cross sectional study of Patients diagnosed with hypertension either admitted in ward or attending OPD of Medical College and Tertiary Care Centre. Urine microalbumin creatinine ratio was used for estimation of microalbuminuria. Conclusion: It was proved that microalbuminuria prevalence was directly proportional to the duration of hypertension, the stage of hypertension. Prevalence of microalbuminria was low in ACE inhibitor and ARB treated hypertensive patients.

ObjectivesThis study aimed to assess the relationship between infection with multiple human papillomavirus (HPV) types and abnormal anal cytology in HIV-infected men.DesignAn observational, cross-sectional study.SettingA regional referral hospital in Taiwan.ParticipantsIn total, 714 HIV-infected men were enrolled between March 2011 and June 2016. Thin preparation anal Pap smears were interpreted according to the 2001 Bethesda System. Thirty-seven types of HPV were detected by reverse line blotting, including 13 oncogenic types and 24 non-oncogenic types.Outcome measuresThe relationship between anal HPV infection and abnormal anal cytology in people of Asian ethnicity and the coverage efficacy in HPV-vaccinated HIV-infected men.ResultsOn anal cytology, 175 (24.5%) subjects had atypical squamous cells of undetermined significance (ASCUS) or higher grades of dysplasia, including 87 (49.7%) with ASCUS, 73 (41.7%) with low-grade squamous intraepithelial lesions (LSILs) and 15 (8.6%) with high-grade squamous intraepithelial lesions (HSILs). A higher proportion of subjects with those without LSIL/HSIL (93.1% vs 67.3%, P<0.0001) had multiple HPV types. The odds of having LSIL/HSIL increased with an increasing number of HPV types: the ORs ranged from 1 for no HPV types to 6.96 (95% CI 2.38 to 20.37) for more than five types (Ptrend<0.0001). Multivariate logistic regression analysis showed a significant association between LSIL/HSIL and the number of HPV genotypes present (OR 1.20; 95% CI 1.02 to 1.42, P<0.05). HPV types covered by the nonavalent HPV vaccine (types 6/11/16/18/31/33/45/52/58) were detected in 70.1% of the patients in this study.ConclusionsThe odds of having anal LSIL/HSIL are approximately seventimes greater in HIV-infected men with than withoutsix or more types of HPV. Multiple HPV types in HIV-infected patients deserves aggressive follow-up, and HPV vaccination programme require scaling up.

BACKGROUND Breast carcinoma is the most well-known malignancy in women. Different predictive and prognostic factors, for example, estrogen receptors (ER), progesterone receptors (PR) and human epidermal growth factor receptor (Her2neu), and Ki67 could inuence breast carcinoma behaviour, yet to date no authoritative connection has been set up among them and breast carcinoma subtypes. In this way present study was done to determine the interrelationships of these predictive and prognostic factors for breast carcinoma. METHODS In this cross sectional study, a total of 50 lumpectomy, modied radical mastectomy specimens of diagnosed carcinoma breast were included in this study. The histopathological grading of the breast carcinoma was performed by Nottingham modication of the Bloom Richardson grading system. All the cases went through immunohistochemistry for ER, PR, Her2neu and Ki67 expression. Association of ER, PR, Her2neu and Ki67 with different histomorphology was established. RESULTS The ER positivity was signicantly lower in tumors >5 cm size whereas Ki67was signicantly increased with increased tumor size. The ER positivity was signicantly lower in high grade tumors as compared to low grade tumors. The positive ER, PR, Her2neu and Ki67 were comparable in between premenopausal and post-menopausal age groups CONCLUSION The present study concludes that ER, PR show inverse while ki67 showed a direct relationship with the tumor grade. Correlation of histomorphology of breast tumor and Her2neu status could not be established.

Abstract Objectives Low-grade papillary urothelial carcinoma (LGUC) has overall a preserved orderly appearance, minimal variability in architecture, and lack of significant cytologic atypia and mitotic activity without pleomorphism. A total of 53.8% of LGUC cases recur with 18.3% progression to high-grade UC. Even focal HGUC in LGUC can be a harbinger of progression. Accurate pathological interpretation is paramount in predicting recurrence and determining treatment. Methods A 63-year-old male with a past medical history of coronary artery disease, benign prostate hyperplasia, and obesity was referred to urology with a chief complaint of chronic hematuria. Cystoscopy with transurethral resection of bladder tumor was performed, which revealed mainly LGUC with focal high-grade-appearing UC. Results Histologic sections revealed papillary architecture with fused fronds, low-grade nuclear atypia, and scattered mitoses comprising 95% of the tissue submitted. No muscular wall invasion by carcinoma was seen. However, in one section, collections of large cells with well-defined cytoplasmic borders, multinucleation, and rare nuclear grooves were identified. The morphology raised the suspicion of a focal HGUC. Diffuse expression of CK20 and low Ki-67 proliferation index (1%) favored umbrella cells. Conclusion Our case reinforces the fact that sectioning can reveal foci, suspicious for HGUC, especially in urothelium. However, proper interpretation of morphology combined with the help of immunohistochemistry aids in accurate diagnosis, which is critical in determining proper clinical management of the patient.

Abstract Background According to the Brazilian Guidelines on Cervical Cancer Screening, women with cytopathologic diagnosis of high-grade intraepithelial lesion, abnormal colposcopic findings, fully visible squamocolumnar junction, and age 25 years or older should be treated at the first visit (“see and treat – S&T”). The main limitation to this approach is the risk of overtreatment, identified by histology without preinvasive lesion. This study aimed to measure the negative histology rate in women submitted to S&T according to the Brazilian Guidelines. Methods This was a cross-sectional study that analyzed records from a database with 616 women submitted to S&T from 1996 to 2017. Negative histology was defined as the following histopathologic results: HPV without CIN, inflammatory, low-grade squamous intraepithelial lesion (LSIL), and CIN 1. Results Of the 616 women, there were 52 (8.44% − 95%CI 6.25–10.64%) with a histopathologic report without preinvasive cervical lesion. No statistical association was found between this outcome and younger ages or a significant downward trend over time. Conclusion The overtreatment rate in this study can be considered low and consistent with the acceptable rates reported in the literature, reinforcing the prevailing Brazilian guideline, in which the benefits of immediate treatment outweigh the risk of losses following biopsy.
