Introduction: To describe the prevalence of infectious diseases in immigrants.
Methods: The Mantoux tuberculin skin test and serology testing for hepatitis B, hepatitis C, HIV and syphilis were performed in 488 immigrants.
Results: A positive reaction to the Mantoux (> or = 10 mm) was found in 19.1% of individuals from Africa, 9.6% from Eastern Europe and 5.8% from South America (p < 0.001). With regard to hepatitis B, 2.5% of the Africans, 2.1% of the Eastern Europeans and none of the South Americans were carriers of the virus (p 5 0.02).
Conclusions: The prevalence of infectious diseases in immigrants varies according to their country of origin.

Hepatocellular carcinoma (HCC) is one of the most common forms of primary liver cancer worldwide. Herein, we present a review article that provides a broad overview of the current landscape of HCC, including the etiology, potential risk factors, and molecular pathways that can serve as potential therapeutic targets. The risk factors tend to vary depending on the geographic distribution; hepatitis B-induced cirrhosis and HCC occur more frequently in Asia and Sub-Saharan Africa, whereas metabolic disorders are the culprits in Western Europe and the Americas.

This study describes a 64-year-old female with a history of hepatitis C and cryoglobulinemia, who presented with respiratory symptoms, including dry cough, shortness of breath, and fever, alongside joint pain and fatigue. Initial workup revealed interstitial pneumonia, supported by chest imaging, and the patient was treated for pneumonia with standard antibiotic therapy. Despite no renal involvement, a hallmark of cryoglobulinemia, further testing confirmed elevated serum cryoglobulin levels.

Hepatogastroenterology and Infectious Diseases Department, Faculty of Medicine, Al-Azhar University, Cairo, Egypt.
Background: Tissue damage by viral hepatitis is a major cause of morbidity and mortality worldwide. Oxidation reactions and reactive oxygen species (ROS) transform proteins and lipids in plasma low-density lipoproteins (LDL) into the abnormal oxidized LDL (ox-LDL). Hepatitis C virus (HCV) infection induces oxidative/nitrosative stress from multiple sources, including the inducible nitric oxide synthase (iNOS), the mitochondrial electron transport chain, hepatocyte NAD(P)H oxidases (NOX enzymes), and inflammation.

Unlabelled: Cytomegalovirus (CMV) is a human herpes virus with a worldwide seroprevalence of 60-100%, mainly known to cause severe life-threatening disease in immunocompromised patients. In immunocompetent hosts (IMCh), CMV causes a self-limiting mononucleosis-like infection, and severe pictures are less recognized. We report a case of a previously healthy 62-year-old woman evaluated in the Internal Medicine outpatient clinic for 3 weeks of progressive fatigue, generalised inflammatory arthralgias, hypogastric discomfort and daily persistent fever.

Background: Nitrofurantoin is a prevalent antibiotic used to treat urinary tract infections. Despite nitrofurantoin's general safety, it can cause serious side effects, including acute pulmonary toxicity, fulminant hepatitis, and severe systemic inflammatory responses, which may mimic conditions such as ischemia and infection. However, reports of acute systemic inflammatory response syndrome after nitrofurantoin ingestion are uncommon in medical literature.
