Introduction: Gall Bladder Carcinoma (GBC) is a diagnostic and a therapeutic challenge. Although it is increasing, chronic cholecystitis remains the most worldwide gall bladder lesions, harbouring many epithelial changes that may end in carcinoma. Aim: To investigate the expression of HER2/neu (Human Epidermal Growth Factor Receptor 2), Ki-67 and MUC1 (Mucin 1) in malignant and non-malignant gall bladder lesions, and to evaluate its relation with clinicopathologic parameters of GBC. Materials and Methods: This retrospective study included 40 cases of GBC, eight cases of gall bladder dysplasia, 10 cases of gall bladder metaplastic changes and 25 cases of chronic cholecystitis as a control group. The blocks were collected from the Department of Pathology of Benha University Hospital, from January 2012 to December 2019. Immunohistochemical staining results of HER2/neu, Ki-67 and MUC1 were analysed and correlated by Statistical Package for the Social Sciences (SPSS) version 16 and Chi-square test or Fisher’s-exact tests. Results: Positive HER2/neu expression (+2, +3) was detected in 47.5% (19/40) of malignant cases and 12.5% (1/8) of dyspastic group, at the same time it was completely absent in the metaplastic and cholecystitis cases (p<0.01). Similarly, Ki-67 Labeling Index (LI) (≥20%) expression was found in 55% (22/40) of malignant group, while it was completely absent in the other three studied groups. All cases of malignant group 100% (40/40), 50% (4/8) of dysplastic one, one case of metaplastic (1/10) showed cytoplasmic expression of MUC1, at the same time it was completely absent in control group (0/25) (p<0.01). High MUC1 expression was found in 75% of both malignant (30/40) and dysplastic (6/8) studied cases and only one case (10%) of metaplastic group (p<0.01). There was a significant correlation between MUC1 expression and studied parameters of GBC. Conclusion: HER2/neu, and Ki-67 are overexpressed in GBC cases compared with control and dysplastic group. The study also highlights that MUC1 would be a better marker of malignant transformation of gall bladder epithelium and its depolarised expression would be reliable for detection of invasive carcinoma, so a new therapeutic agent can target these cell surface adhesion molecule (MUC1). HER2/neu can be considered as a candidate for targeted therapy in GBC treatment strategy.

Objective The current study evaluated the expression of WW domain-containing oxidoreductase (WWOX), its association with clinicopathological features and with p53, Ki-67 (cell proliferation) and CD31 (angiogenesis) expression in patients with invasive cervical squamous cell carcinoma (ICSCC). To the best of our knowledge, no other study has evaluated this association. Methods Women with IB stage-ICSCC (n = 20) and women with uterine leiomyoma (n = 20) were prospectively evaluated. Patients with ICSCC were submitted to type B-C1 radical hysterectomy and pelvic lymphadenectomy. Patients in the control group underwent vaginal hysterectomy. Tissue samples were stained with hematoxylin and eosin for histological evaluation and protein expression was detected by immunohistochemistry studies. Results The WWOX expression was significantly lower in the tumor compared with the expression in the benign cervix (p = 0.019). The WWOX expression was inversely associated with the CD31 expression in the tumor samples (p = 0.018). There was no association between the WWOX expression with the p53 expression (p = 0.464) or the Ki-67 expression (p = 0.360) in the samples of invasive carcinoma of the cervix. There was no association between the WWOX expression and tumor size (p = 0.156), grade of differentiation (p = 0.914), presence of lymphatic vascular invasion (p = 0.155), parametrium involvement (p = 0.421) or pelvic lymph node metastasis (p = 0.310) in ICSCC tissue samples. Conclusion The results suggested that WWOX may be involved in ICSCC carcinogenesis, and this marker was associated with tumor angiogenesis.

Objective: To evaluate the association between metabolic syndrome (MS), obesity, and central fat deposition with the immunohistochemical profile (IHC) of breast cancer (BC) in postmenopausal women. Methods: A comparative cross-sectional clinical study was carried out with 63 women with recent BC and MS, compared to 126 women with recent BC, without MS (control group). Inclusion criteria were: women aged 45-75 years, amenorrhea >12 months, without previous cancer treatment, attended at a University Hospital. The groups were matched for age, time since menopause, and body mass index (BMI), in the proportion of 1 case for 2 controls, according to the sample calculation of at least 186 women in their entirety. Clinical and anthropometric data were collected; tumor size and grade and the IHC profile (ER, PR, HER2, and Ki67). By IHC convention, tumors were grouped into five subtypes: Luminal A (ER+, PR+, HER-2 -, and Ki-67 <14%); Luminal B HER-2 - (ER+, PR+ or -, HER-2 -, and Ki-67≥14%); Luminal B HER-2+ (ER+, PR+ or -, HER-2+, and any Ki-67); Non-luminal HER-2 (ER-, PR-, HER2+, and any Ki-67); and Triple-negative (ER-, PR-, HER2-, and any Ki-67). Women with three or more diagnostic criteria were considered with MS: waist circumference (WC)>88 cm; TG≥150 mg/dL; HDL cholesterol<50 mg/dL; blood pressure ≥130/85 mmHg; glucose ≥100 mg/dL. For statistical analysis, the Student’s t-test, Gamma Distribution, χ2 test and logistic regression (odds ratio–OR) were used. Results: Among the participating women, the mean age, time since menopause and BMI were: 59.0±10.6 years, 11.4±9.6 years, and 28.5±5.5 kg/m2, respectively; there was no statistical difference in the comparison between the groups. Women with MS had a higher occurrence of tumors ≤2cm when compared to those without MS (49.2 vs. 31.8%, respectively) (p=0.038). Women with MS had a higher incidence of tumors with PR-positive (p=0.046), HER2-negative (p=0.038), when compared to women without MS (79.4 vs. 65.8% and 44.5 vs. 27.8%, respectively). In obese patients (BMI≥30 kg/m2), a higher proportion of HER2 negative tumors (p=0.047) was observed when compared to non-obese women (43.9 vs. 27.7%, respectively). In the multivariate analysis, a higher risk for tumors of the Luminal B HER-2 negative subtype was observed among women with MS (OR 2.00, 95%CI 1.03‒3.89), obese (OR 2.03, 95%CI 1.06‒3.90), and with central deposition of fat (OR 1.96, 95%CI 1.01‒4.03). Conclusion: Metabolic syndrome, obesity, and central fat deposition correlate with factors of good prognosis for breast cancer, such as tumors ≤2 cm, PR+ and HER2-, in postmenopausal women.

Background: The most commonly received specimen in any histopathology laboratory is cholecystectomy specimen. The majority of the cholecystectomies are done for Cholelithiasis. Inflammation may be acute, chronic or acute on chronic. It almost always occurs in association with gallstones, which is responsible for carcinoma and if the diagnosed early prognosis of the carcinoma gall bladder is good. Histopathological examination is therefore a must for diagnosis of early carcinomas. Subjects and Methods: 100 cholecystectomy specimens from patients       of all ages were included. All specimens were subjected to gross and microscopic assessment. Different histological findings were noted in various layers of the gall bladder. The study includes all radiologically confirmed inflammatory pathologies of including metaplastic changes of the gall bladder epithelium, irrespective of age and sex. The study excludes patients with evident gallbladder malignancy, cases with known secondaries from gall bladder, traumatic rupture of gallbladder. Results: The age of patients varied from 16 to 70 years, with a maximum number of patients (25%) belong to 31 to 40 years. Gall stones were associated with 59% cases of cholecystitis. Pigment stones were most common (74%). Histopathologically the most common diagnosis was chronic cholecystitis (69%). Conclusion: Almost all of the gallbladder lesions are inflammatory in origin, of which the most common disease being chronic cholecystitis. Chronic cholecystitis was found to be most probable diagnosis in a female of 30-40 years. Pigmented gall stones were found to be the most common etiology of chronic cholecystitis. Prompt detailed histopathological analysis will help to confirm the benign nature of the disease or to detect any precursors of malignancy.

Objectives: Studying on the variation in CA 72-4 levels of the gastric cancer’s patients before and after 10 days and 30 days surgery treatment. Materials and methods: The studying group included 42 gastric cancer’s patients who were examinated and treated in cancerology service of Hue University Hospital and gastroenterology service of Hue Central Hospital. The control group included 30 healthy normal examinated at Hue University Hospital. The study groups were clinical, endoscopic anatopathologic examination diagnosed with gastric cancer and quantitative levels of CA 72-4 in three times points: before surgerying, after surgerying 10 days and 30 days postoperatively. Rerults: The concentration of CA 72-4 in gastric cancer’s patients was 10.06 ± 16.49 U/ml. Clearly higher than the control group 1.2 ± 0.4 U/ml(p <0.01). The rate increased levels of CA 72-4 in gastric cancer’s patients before surgerying was 27.5% and the control group was 0%. After 10 days of surgery, CA 72-4 level was 5.56 ± 8.55 U/ml; 82.5% of patients have reduced levels of CA 72-4 and 17.5% no changes; there are 0% increased cases. After 30 days of surgery, CA 72-4 level was 3.79 ± 6,52 U/ml. CA 72-4 level 10 days after surgering have decreased significantly compared to before surgery (p < 0.05) and 30 days after surgery have decreased significantly compared to after 10 days (p < 0.05). 30 days postoperatively, 90% patients had reduced levels of CA 72-4, 10% no changes, no patient had increased levels of CA 72-4 and no patient be relapsed after 30 days of treatment. Conclusions: CA 72-4 concentrations before surgerying increased 27.5%, after surgery 10 days and 30 days reduced step by step, no case have increased CA 72-4 levels, no case relapsed after 30 days.

Background: Thyroid diseases occur more frequently in people exposed to ionizing radiation, but the relationship between occupational exposure to ionizing radiation and thyroid pathologies still remains unclear. Objective: To evaluate the prevalence of thyroid diseases in healthcare workers exposed to low-level ionizing radiation compared with a control group working at the University Hospital of Bari, Southern Italy, and living in the same geographical area, characterized by mild iodine deficiency. Methods: We ran a cross-sectional study to investigate whether healthcare workers exposed to ionizing radiation had a higher prevalence of thyroid diseases. Four hundred and forty-four exposed healthcare workers (241 more exposed, or “A Category”, and 203 less exposed, or “B Category”) and 614 nonexposed healthcare workers were enrolled during a routine examination at the Occupational Health Unit. They were asked to fill in an anamnestic questionnaire and undergo a physical examination, serum determination of fT3, fT4 and TSH, anti-TPO ab and anti-TG ab and ultrasound neck scan. Thyroid nodules were submitted to fine needle aspiration biopsy when indicated. Results: The prevalence of thyroid diseases was statistically higher in the exposed workers compared to controls (40% vs 29%, adPR 1.65; IC95% 1.34-2.07). In particular, the thyroid nodularity prevalence in the exposed group was approximately twice as high as that in the controls (29% vs 13%; adPR 2.83; IC95% 2.12-3.8). No statistically significant association was found between exposure to ionizing radiation and other thyroid diseases. Conclusion: In our study, mild ionizing radiation-exposed healthcare workers had a statistically higher prevalence of thyroid diseases than the control group. The results are likely due to a closer and more meticulous health surveillance programme carried out in the ionising radiation-exposed workers, allowing them to identify thyroid alterations earlier than non-exposed health staff.

Abstract Background and Aims Vascular calcification (VC) plays a major role in cardiovascular disease (CVD), which is one of the main causes of mortality in patients with chronic kidney disease (CKD). The study aims at early detection of breast arterial calcification (BAC) in different stages of CKD (stage 2, 3& 4) patients as an indicator of systemic VC. Method A case control study was conducted targeting CKD women, aged 18- 60 years old. The sample was divided into 3 groups; A,B,C (representing stage 2, 3 & 4 of CKD) from women who attended nephrology and Internal medicine clinics and admitted in inpatient ward in Suez Canal University Hospital. A 4th group (D) was formed as a control group and included women with normal kidney functions (each group (A, B, C, D) include 22 women). The selected participants were subjected to history taking, mammogram to detect BAC and biochemical assessment of lipid profile, Serum creatinine (Cr), Mg, P, Ca, PTH and FGF23. Results Our study detected presence of BAC in about 81.8% of hypertensive stage 4 CKD patients compared with 50% in stage 3 CKD, also in the majority of stage 4 CKD patients who had abnormal lipid profile parameters and electrolyte disturbance. Most of the variables had statistical significance regarding the presence of BAC. Conclusion Although it is difficult to determine the definite stage at which the risk of VC begins but in our study, it began late in stage 2 CKD, gradually increased prevalence through stage 3 and became significantly higher in stage 4. These results suggest that preventive strategies may need to begin as early as stage 2 CKD.

Abstract Objective To evaluate the role of Ki-67 in predicting subsequent intravesical recurrence following radical nephroureterectomy and to develop a predictive nomogram for upper tract urothelial carcinoma patients. Methods This retrospective analysis involved 489 upper tract urothelial carcinoma patients who underwent radical nephroureterectomy with bladder cuff excision. The data set was randomly split into a training cohort of 293 patients and a validation cohort of 196 patients. Immunohistochemical analysis was used to assess the immunoreactivity of the biomarker Ki-67 in the tumor tissues. A multivariable Cox regression model was utilized to identify independent intravesical recurrence predictors after radical nephroureterectomy before constructing a nomographic model. Predictive accuracy was quantified using time-dependent receiver operating characteristic curve. Decision curve analysis was performed to evaluate the clinical benefit of models. Results With a median follow-up of 54 months, intravesical recurrence developed in 28.2% of this sample (n = 137). Tumor location, multifocality, pathological T stage, surgical approach, bladder cancer history and Ki-67 expression levels were independently associated with intravesical recurrence (all P &lt; 0.05). The full model, which intercalated Ki-67 with traditional clinicopathological parameters, outperformed both the basic model and Xylinas’ model in terms of discriminative capacity (all P &lt; 0.05). Decision-making analysis suggests that the more comprehensive model can also improve patients’ net benefit. Conclusions This new model, which intercalates the Ki-67 biomarker with traditional clinicopathological factors, appears to be more sensitive than nomograms previously tested across mainland Chinese populations. The findings suggest that Ki-67 could be useful for determining risk-stratified surveillance protocols following radical nephroureterectomy and in generating an individualized strategy based around intravesical recurrence predictions.

The antibiotic stewardship program (ASP) is a necessary part of febrile neutropenia (FN) treatment. Pharmacist-driven ASP is one of the meaningful approaches to improve the appropriateness of antibiotic usage. Our study aimed to determine role of the pharmacist in ASPs for FN patients. We prospectively studied at Thammasat University Hospital between August 2019 and April 2020. Our primary outcome was to compare the appropriate use of target antibiotics between the pharmacist-driven ASP group and the control group. The results showed 90 FN events in 66 patients. The choice of an appropriate antibiotic was significantly higher in the pharmacist-driven ASP group than the control group (88.9% vs. 51.1%, p < 0.001). Furthermore, there was greater appropriateness of the dosage regimen chosen as empirical therapy in the pharmacist-driven ASP group than in the control group (97.8% vs. 88.7%, p = 0.049) and proper duration of target antibiotics in documentation therapy (91.1% vs. 75.6%, p = 0.039). The multivariate analysis showed a pharmacist-driven ASP and infectious diseases consultation had a favorable impact on 30-day infectious diseases-related mortality in chemotherapy-induced FN patients (OR 0.058, 95%CI:0.005–0.655, p = 0.021). Our study demonstrated that pharmacist-driven ASPs could be a great opportunity to improve antibiotic appropriateness in FN patients.
