Histopathological Profile of Different Breast Lesions: A Single-Center Observational Study.

OBJECTIVE: To describe the histopathological pattern of different breast lesions among tissue specimens sent to our laboratory. METHOD: A record-based study using a retrospective review of 255 histologically diagnosed breast biopsy reports in the histopathology department of authors from December 2016 to November 2021 was conducted. The specimens were collected from core biopsy, lumpectomy, and mastectomy. All data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS) version 28 (IBM SPSS Statistics, Armonk, NY). Then, the findings were presented using text, tables, and charts. RESULT: A total of 255 breast lesions were analyzed in this study. Most of the cases were benign (58.8%), followed by inflammatory lesions (21.6%), and malignant (19.6%). Fibroadenoma was the most prevalent benign lesion (36.7%), and most of the patients (70.9%) were in the age group of 20-39 years old. The most common inflammatory lesion was granulomatous mastitis (56.4%), and most of the cases were diagnosed in the age group of 30-39 years old. Invasive ductal carcinoma (IDC) was the most encountered histological type of carcinoma (62%). Of the malignant cases, 52% were diagnosed before the age of 50 years. Among these 50 cases, grade 2 was the most prevalent one (46%). CONCLUSION: Benign breast lesions are more common than malignant breast lesions, and fibroadenoma is the most common benign subtype. Granulomatous mastitis is the most prevalent inflammatory breast lesion. About two-thirds of malignant cases are non-Arab. Invasive ductal carcinoma with no special type (NST) is the most common malignant subtype.

Exploring the prevalence of Human Papillomavirus (HPV) genotypes in PAP smear samples of women in northern region of United Arab Emirates (UAE): HPV Direct Flow CHIP system-based pilot study.

OBJECTIVE: The aim of this study was to explore the prevalence of low and high-risk HPV genotypes in PAP smear samples of women in northern region of the UAE using HPV direct flow CHIP method. METHODS: A cross-sectional retrospective study was conducted between September 2021 to April 2022. A total of 104 liquid-based cervical cytology samples were obtained from women aged 20-59 years attending the Gynaecology out-patient department of Thumbay University Hospital and other hospitals of Northern Emirates of UAE, processed for the routine cytological examination to identify and differentiate morphological changes of the PAP smear samples. HPV genotyping was performed using HPV direct flow CHIP method. RESULTS: In total, 112 HPV genotypes were detected in 63 women (60.57%) included 18 abnormal cytological and 45 normal epithelial samples. 63 LR and 49 HR HPV genotypes were identified in all the 63 positive samples. Highest rate of infection with multiple LR and HR HPV genotypes were detected in women aged 40-49 years (25.9%) and 20-29 years (23.5%). Infection by HPV6 (13.46%), HPV11 (9.61%), HPV16 (9.61%), HPV62/81 (7.69%) and HPV45 (7.69%) were the most common genotypes. A moderate increase than expected incidence of HPV45 and 62/81 (7.69%) were detected. Co-infection with multiple low and high-risk genotypes is present in 20.2% cases; in that, HPV6 (15.9%) was the most common followed by HPV62/81 (12.7%) and HPV16 (11.11%). The prevalence of HPV18 was found to be 1.6%. CONCLUSION: The genotypes 6, 45, 16, 11, 67, 62/81 were the most common HPV infections in the women between the age group of 21 and 59-years-old. A moderate increase of HPV45, 62/81 and much less prevalence of HPV18 were detected in the study population. 43.27% of the normal epithelia were positive to different low and high-risk HPV genotypes. This finding highlights the importance of molecular genotyping of HPV to emphasize the cervical screening triage.

Effect of different antidiabetic medications on atherosclerotic cardiovascular disease (ASCVD) risk score among patients with type-2 diabetes mellitus: A multicenter non-interventional observational study.

OBJECTIVE: The aim of this study was to compare the clinical outcomes associated with different combinations of oral diabetic drugs among patients with type 2 diabetes mellitus. METHOD: A prospective multicenter longitudinal, noninterventional observation study design was applied. At baseline (0 month), clinical parameters including glucose profile, renal function, lipid profile and risk assessment for cardiovascular risks were calculated. Mean Weighted difference (MWD) with heterogeneity and effect z was calculated to determine the risk reduction at the end of the study. RESULTS: A total of 1,657 were enrolled to different cohorts with response rate of 75.5%. The distribution of patients was based on prescribed drug. A total of 513 (30.9%) in G1 (metformin alone), 217 (13.09%) in G2 (metformin with Glimepiride), 231 (12.85%) in G3 (Metformin with Gliclazide), 384 (23.17%) in G4 (metformin with Sitagliptin) and 312 (18.89%) in G5 (Metformin with Saxagliptin). There was no significant different in all clinical and social variables at baseline. The Intergroup analysis showed significant differences with all the primary outcome variables except BMI (p = 0.217) and eGFR (p = 0.782) among patients using sulphonylurea (SU) combination (G2 & G3). Findings also showed significant high frequency of emergency visit and hospitalization in G1 (78.16% & 30.8%) as compared to SU (70.1% & 28.3%, p = 0.001) and DPP-4 (56.6% & 20.4%, p = 0.001). The overall reported effect was z = 2.58, p = 0.001 for ASCVD risk reduction assessment. CONCLUSION: The study concluded that significant effect of Dipeptidyl peptidase-4 inhibitor on reduction of hospitalization, lipid profile and also ASCVD risk score of type-II diabetes mellitus patients regardless of clinical comorbidities. Also, sulfonylurea combinations have showed significant reduction in LDL and triglycerides values.
