Background: Bladder Cancer (BCa) is the tenth most incident malignancy worldwide. BCa is mostly attributed to environmental exposure and lifestyle, particularly tobacco smoking. The Aryl Hydrocarbon Receptor Repressor (AhRR) participates in the induction of many enzymes involved in metabolizing carcinogens, including tobacco smoke components.

Purpose: Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes.

Bladder cancer (BCa) is an exophytic tumor that presents as either noninvasive confined to the mucosa (NMIBC) or invading the detrusor muscle (MIBC), and was recently further subgrouped into molecular subtypes. Arylamines, major BCa environmental and occupational risk factors, are mainly metabolized by the genetically polymorphic N-acetyltransferases 1, NAT1 and NAT2. In this study, we investigated the association between N-acetyltransferases genetic polymorphism and key MIBC and NMIBC tumor biomarkers and subtypes.

Point-of-care ultrasound may be an alternative to radiographs for diagnosing long bone fractures when medical resources are limited. Safe and timesaving, ultrasound also can be used in the ED as a screening tool for suspected long bone fractures and can detect associated musculoskeletal injuries. Ultrasound can be used in radiation-sensitive patients such as children and pregnant patients.

Urinary bladder cancer incidence in Lebanon ranks among the highest in the world. Cytochrome P450 2E1 (CYP2E1), NAD(P)H quinone oxidoreductase1 (NQO1), and N-Acetyltransferase1 (NAT1), are drug-metabolizing enzymes (DMEs) involved in the metabolism of carcinogens, such as arylamines and heterocyclic amines, implicated in bladder cancer. The present study attempts to investigate the role of these DMEs genetic polymorphism in bladder cancer risk among Lebanese men.

Background: Bladder cancer is the second most incident malignancy among Lebanese men. The purpose of this study was to investigate potential risk factors associated with this observed high incidence.

Methods: A case-control study (54 cases and 105 hospital-based controls) was conducted in two major hospitals in Beirut.
