Streptococcus pneumoniae is the leading bacterial etiologic agent in acute otitis media (AOM), and it produces a more severe inflammatory response than other otopathogens. Additionally, the presence of multidrug-resistant (MDR) S. pneumoniae is an important issue in the management of AOM. The present pilot study aimed to ascertain whether MDR S. pneumoniae is associated with a higher inflammatory response and/or a more severe disease. ⋯ MDR S. pneumoniae was associated with a more severe inflammatory response and a higher incidence of mastoiditis.

The clinical presentation of pulmonary embolism (PE) can be various and misleading. We analyzed patients with suspicion of PE and subsequently performed computed tomography pulmonary angiography (CTPA) in an emergency department of Internal Medicine, focusing on patient groups in which PE might be underestimated in the emergency setting, such as young patients and patients with low clinical probability. ⋯ CTPA frequently proves a PE in patients with suspicion of PE in an emergency department of Internal Medicine. If PE is suspected and CTPA performed accordingly, the presence of PE is quite common even in low-risk patient groups (Wells score) or in young patients <40 years with chest pain or dyspnea.

Stress can affect learning and memory in students. Previous studies on stress in students were conducted mainly through surveys. We investigated how heart rate variability (HRV)-measured stress is related to academic achievement in medical students during clerkship. ⋯ This study shows that medical students with higher stress measured by HRV have higher academic achievement, especially in written examinations. Further studies are needed to confirm the results of this study and to assess the long-term effects of HRV-measured stress on medical students.

C. nivariensis is a rare Candida species which is phenotypically closely related to Candida glabrata and Candida bracarensis. The 3 species form the C. glabrata sensu lato complex. Here, we describe the first isolation and characterization of a C. nivariensis isolate cultured from the tracheal aspirate obtained from a young man in Kuwait. ⋯ This report extends the geographic distribution of C. nivariensis to the Arabian Peninsula. MALDI-TOF MS with updated software and molecular tests are needed to correctly identify C. nivariensis. Since C. nivariensis may exhibit reduced susceptibility to antifungal agents, accurate identification and antifungal susceptibility testing are essential, particularly for isolates from sterile sites, for optimal patient management.

to analyse cataract surgery outcomes and related factors in eyes presenting with good visual acuity. ⋯ Visual acuity improved significantly, although at least 8.1% of them did not reach their pinhole preoperative visual acuity. Worse visual acuity outcomes were associated with increasing age, vitreous loss, and iris trauma. The 6/9 vision threshold may not be able to accurately differentiate those who may benefit from cataract surgery and those who may not.
