Tumor-like conditions that mimic liver tumors.

Non-neoplastic tumor-like conditions of the liver can appear similar to hepatic neoplasms. In many cases, a biopsy is required to confirm the pathology. However, several tumor-like conditions can be correctly diagnosed or suggested prospectively, thus saving patients from unnecessary anxiety and expense.

Risk Factors for Postoperative Infections Following Appendectomy of Complicated Appendicitis: A Meta-analysis and Retrospective Single-institutional Study.

Patients with complicated appendicitis have an increased risk for postoperative infections. Potential risk factors for postoperative infections through a meta-analysis and retrospective chart review are discussed. A meta-analysis consisting of 35 studies analyzing complicated appendicitis treated with an appendectomy noting at least 1 postoperative infection was performed.

Recommend with caution: A meta-analysis investigating papillary thyroid carcinoma tumor progression under active surveillance.

Background: Papillary thyroid carcinoma (PTC) is an indolent disease with favorable outcomes. The non-surgical treatment approach known as active surveillance (AS) has been introduced as an alternative treatment instead of the traditional thyroidectomy. However, 10-15 % of PTC tend to progress.

Sexual Harassment: Knowledge, Prevalence, Pattern, and Impacts Among Egyptian Female College Students.

Sexual harassment (SH) is an uprising problem worldwide, especially in Egypt. This study aims to determine the magnitude, patterns, and circumstances of SH among female students at Suez Canal University. A cross-sectional study was conducted on a representative female student sample () from all the faculties using a self-administered anonymous questionnaire.

Defining invasion in breast cancer: the role of basement membrane.

Basement membrane (BM) is an amorphous, sheet-like structure separating the epithelium from the stroma. BM is characterised by a complex structure comprising collagenous and non-collagenous proteoglycans and glycoproteins. In the breast, the thickness, density and composition of the BM around the ductal lobular system vary during differing development stages.

Positive Predictive Value for the Malignancy of Mammographic Abnormalities Based on the Presence of an Ultrasound Correlate.

To compare the outcomes of different mammographic lesions based on the presence of an ultrasound (US) correlate and to estimate how often targeted US can identify such lesions. This retrospective study included all consecutive cases from 2010 to 2016, with Breast Imaging Reporting and Database System (BI-RADS) categories 4 & 5 who underwent US as part of their diagnostic workup. We compared the incidence of malignancy between lesions comprising a US correlate that underwent US-guided core needle biopsy (CNB) and those without a correlate that underwent stereotactic CNB.

Setting: All the 27 public primary healthcare centres in Qatar.

Expressed Breast Milk Contamination in Neonatal Intensive Care Unit.

Background: The health benefits of breastfeeding are well known. However, some ill babies including those admitted to the neonatal intensive care unit (NICU) cannot be directly breastfed. In this situation, expressed breast milk (EBM) can be used.

Stress, anxiety and depression among healthcare workers facing COVID-19 pandemic in Egypt: a cross-sectional online-based study.

Objective: This study assessed perceived stress, anxiety and depression among healthcare workers facing the COVID-19 pandemic in Egypt.

Setting: This was an online study where a Google form was prepared including sociodemographic and occupational data as well as three validated questionnaires to assess perceived stress, anxiety and depression, respectively. The form was distributed online to all social media groups including healthcare workers all across the country, and responses were collected until the sample size of 262.

Rationales and uncertainties for aspirin use in COVID-19: a narrative review.

Objectives: To review the pathophysiology of COVID-19 disease, potential aspirin targets on this pathogenesis and the potential role of aspirin in patients with COVID-19.

Design: Narrative review.

Setting: The online databases PubMed, OVID Medline and Cochrane Library were searched using relevant headlines from 1 January 2016 to 1 January 2021.

Non-neovascular age-related macular degeneration with subretinal fluid.

Purpose: To evaluate the various patterns of subretinal fluid (SRF) in eyes with age-related macular degeneration (AMD) in the absence of macular neovascularisation (MNV) and to assess the long-term outcomes in these eyes.

Methods: This retrospective study included only eyes with non-neovascular AMD and associated SRF. Eyes with evidence of MNV were excluded.

Efficient production of GGTA1 knockout porcine embryos using a modified handmade cloning (HMC) method.

Handmade cloning is a zona-free nuclear transfer approach and an economical, efficient, and simple micromanipulation-free alternative to dolly based traditional cloning (TC). In this study, based on handmade cloning with minor modifications, an optimized bi-oocyte fusion (BOF) cloning method was established to produce GGTA1 KO porcine embryos using the CRISPR/Cas9 gene editing system. The GGTA1 gene is responsible for the generation of Gal epitopes on the surface of porcine cells, triggering hyperacute immune rejection in preclinical porcine-to-human xenotransplantation.

Venous glucose, serum lactate and base deficit as biochemical predictors of mortality in patients with polytrauma.

Background: The trauma and injury severity score (TRISS) and Acute Physiology and Chronic Health Evaluation IV (APACHE IV) are accurate but complex. This study aimed to compare venous glucose, levels of serum lactate, and base deficit in polytraumatized patients as simple parameters to predict the mortality in these patients versus (TRISS) and (APACHE IV).

Methods: This was a comparative cross-sectional study of 282 patients with polytrauma presented to the Emergency Department (ED).

Role of Nigella sativa seed oil on corneal injury induced by formaldehyde in adult male albino rats.

Formaldehyde is frequently used in occupational environments, its toxicity concerns to all who work closely with it such as anatomists. Nigella sativa is an amazing herb with a rich historical and religious background; its seeds are the source of its active ingredients. The purpose of the present study was to evaluate the role of Nigella sativa oil on corneal injury induced by formaldehyde in adult male albino rats.

Depo-Provera Versus Norethisterone Acetate in Management of Endometrial Hyperplasia Without Atypia.

The objective of this study was to assess effectiveness and safety of Depo-Provera (medroxyprogesterone acetate) in treatment of endometrial hyperplasia (EH) and to compare it with norethisterone acetate (NETA) as an oral progestogen treatment. One hundred forty six women aged 35 to 50 years with abnormal uterine bleeding and diagnosed as having EH were randomized to receive either Depo-Provera, one injection every 3 months for 6 months (2 doses), or oral cyclic NETA, 15 mg daily for 14 days per cycle for 6 months. Primary outcome measure was regression of EH.

Long term effects of maternal protein restriction on postnatal lung alveoli development of rat offspring.

Poor nutrition of women during pregnancy causes reduction in foetal growth and can adversely affect the development of the foetal lungs. The purpose of the present study was to assess the effects of maternal protein restriction on the postnatal lung development in neonatal period, and on lung structure in adult rat offspring. Female virgin Sprague-Dawley albino rats (more than 200 g) were used.

Antegrade-retrograde opposing lag screws for internal fixation of simple displaced talar neck fractures.

The talar neck is deviated medially with reference to the long axis of the body of the talus. In addition, it deviates plantarward. The talar neck fracture line is sometimes observed to be oriented obliquely (not perpendicular to the long axis of the talar neck).

Quantitative and qualitative assessment of flowmetrograms in patients with prostatodynia.

Objectives: Prostatodynia (type III-B according to the classification of the National Institute of Diabetes and Digestive and Kidney Diseases) represents a major part of all chronic prostatitis syndromes. Uroflowmetry changes in these patients were rarely described, and discrepancies exist about the prevalence of urodynamic abnormalities. The aim of this study was to describe both qualitative and quantitative flowmetrogram characteristics in these patients.
