Cyclic imides as building blocks in the synthesis of natural products, drugs and polymers display a diverse of pharmacological activities such as antibacterial, antifungal, anticonvulsant, anticancer, and anti-inflammatory effects. This review summarizes recent findings on antimicrobial activities of cyclic imide derivatives and emphasis on the importance of cyclic imides for drug design and development of new antimicrobial compounds.

Mycobacterium tuberculosis is a causative agent of tuberculosis that causes deaths across the world. The pathogen apart from causing disease manifestations can also enter into a phase of latency to re-emerge later. Among the various factors associated with the virulence of pathogen, the lipids composing the cell wall of the bacillus have drawn much interest among. ⋯ In addition, the lipid profile of the cell wall has been shown to modulate the immune responses launched by the host, especially in the suppression, or production of inflammatory factors, cytokines, and phagocytic cells, such as dendritic cells and macrophages. Apart from M. tuberculosis, the paper also briefly looks at the role of Mycobacterium bovis and its role in tuberculosis in humans along with its lipid profile of its cell wall. This review aims to summarize the various lipids of the cell wall of M. tuberculosis along with their roles in enabling the pathogen to maintain its virulence to infect further humans and its persistence inside the host.

Varicella (chickenpox) is the primary infection of varicella-zoster virus (VZV), it is a mild self-limiting infection, but it is also highly contagious and can cause severe complications among high-risk group of individuals. It is usually a childhood infection providing lifelong immunity, but adults without varicella history are also susceptible to infection. High-risk group of individuals is more likely to develop serious complications. ⋯ Few numbers of studies have reported an obvious reduction in varicella prevalence, hospitalizations, and deaths in the Middle East following varicella vaccination. A basic database about varicella infection before the initiation and implementation of a vaccination policy is essential to determine the target group of individuals. As far as our knowledge, this is the first review about varicella infection in the Middle East.

Case Reports
Endotracheal stent increased survival length in patients with invasive thymic adenocarcinoma.
We reported the first case of inoperative thymic adenocarcinoma successfully palliative treated by the double-stent procedure. In a patient who expressed stridor, computed tomography was done and necrotic mediastinal mass, which protrudes into a trachea, was demonstrated. ⋯ After 1 year, the patient developed gastric aspiration and tracheoesophageal fistula; therefore, the esophageal stent was placed. The outcome was lethal, but the placement of endotracheal stent significantly increased a length of survival for the patient with invasive thymic adenocarcinoma.

Patient safety is a priority in all health-care centers across the world. This study aimed to determine the frequency of events that threaten patient safety and the grade threating of events from the perspective of the health-care professionals in the intensive care units (ICUs). ⋯ The occurrence of events threatening the patient safety in ICUs warrants proper planning by administrators of health-care centers. Medication error was the most frequent and important event of threat to patient safety and falling was the least frequent event of threat to patient safety in ICUs. Considering the frequency and magnitude of medication error in ICUs, a well-adjusted preventive plan should be designed and implemented to improve the patient safety.
