Brucellosis is one of the most common zoonotic infections worldwide caused by gram negative bacilli of the genus Brucella. It is transmitted to humans by contact with infected animals or derived food products such as unpasteurized milk. Brucellosis' clinical presentation varies widely from multi-systemic involvement to asymptomatic infection. We present the case of a 52-year-old Lebanese male who was admitted to our hospital with a 3-week history of fever (up to 40 °C), chills, night sweats and abdominal pain. Abdominal CT scan revealed the presence of several mesenteric lymphadenopathies and some retroperitoneal lymphadenopathies. Blood cultures came back positive for Brucella melitensis, and a follow-up CT of the abdomen done after treatment revealed complete resolution of the lymphadenopathies. To our knowledge, this is the first case in the literature of brucellosis presenting as retroperitoneal and mesenteric lymphadenopathies. In endemic areas, the diagnosis of brucellosis should always be raised in front of any long duration fever even in the absence of a typical clinical presentation.

Objective: We aimed to investigate the association of increased smartphone screen time with insomnia, bedtime procrastination, depression, anxiety, body mass index (BMI), and physical activity during the coronavirus disease of 2019 (COVID-19) pandemic. Methods: An online survey was performed for university students from all regions of Lebanon during the lockdown. The survey included questionnaires about smartphone screen time, diet, physical activity, psychological symptoms, and bedtime procrastination. We defined 6 hours of smartphone use as critical based on a survey done in United States. Results: Among female students, smartphone use duration, physical activity levels, BMI, depression, anxiety, and insomnia severity were significantly higher than in male. When we stratified participants based on 6 hours of smartphone use, females, unhealthy food consumption, insomnia, anxiety, depression, and bedtime procrastination were significantly higher in the group with ≥6 hours of smartphone use. When we divided based on 7 hours, physical activity and body weight also differed between the two groups. Logistic regression analysis revealed that female, overweight, insomnia, and bedtime procrastination were significant predictors of a phone screen time of 7 hours. Conclusion Our findings suggest that adults should be more cautious and responsible when using smartphones and be more concerned about the health-related risks.
