Mannitol Anaphylaxis in the Setting of Septic Emboli-Induced Intracranial Hemorrhage.

Neurological complications are a significant problem in bacterial endocarditis. Cerebral embolism is the most frequent concern. Acute embolic disease may trigger focal seizures or mycotic aneurysms. Miliary infection is also common, and lumbar puncture can guide in determining the infective organism. Purulent cerebrospinal fluid (CSF) consists often of Staphylococcus aureus, a virulent organism, whereas non-virulent organisms (i.e., viridans streptococci) have normal CSF formulae. Microscopic abscesses suggest the potential for aneurysm from bacterial endocarditis amplifying the risk of intracranial hemorrhage. Mannitol and hypertonic (3%) saline are intravenous medications used as a rescue treatment for brain hemorrhage. A patient diagnosed with mycoplasma pneumonia and septic shock secondary to tricuspid endocarditis with extensive pulmonary emboli and metastatic infection to his spine was initiated on antibiotics. He developed a massive intracranial bleed from the rupture of mycotic septic emboli and was given mannitol to decrease intracranial pressure, which caused anaphylaxis.

Cardiac Adverse Events With Remdesivir in COVID-19 Infection.

Since December 2019, coronavirus has gradually progressed to a pandemic with no efficacious treatment. Remdesivir is an antiviral medication and inhibitor of viral RNA dependent RNA polymerase with inhibitory action against SARS-CoV virus. Two patients diagnosed with coronavirus infection with worsening respiratory status were initiated with multimodality therapy with antibiotics, steroids and remdesivir. After initiation of remdesivir, the patients' developed bradycardia, with one of the two also showing signs of worsening QT interval. This reverted upon stopping remdesvir therapy. The prevalence of bradycardia with prolonged QT interval is not well-known yet with this medication.

Indoor fungal concentration in the homes of allergic/asthmatic children in Delhi, India.

Allergy to fungi has been linked to a wide range of illnesses, including rhinitis and asthma. Therefore, exposure to fungi in home environment is an important factor for fungal allergy. The present study was aimed to investigate types of airborne fungi inside and outside the homes of asthmatic children and control subjects (nonasthmatic children). The dominant fungi were evaluated for their quantitative distribution and seasonal variation. The air samples were collected from indoors and immediate outdoors of 77 selected homes of children suffering from bronchial asthma/allergic rhinitis using Andersen volumetric air sampler. The isolated fungal genera/species were identified using reference literature, and statistical analysis of the dominant fungi was performed to study the difference in fungal concentration between indoor and immediate outdoor sites as well as in between different seasons. A total of 4423 air samples were collected from two indoor and immediate outdoor sites in a 1-year survey of 77 homes. This resulted in the isolation of an average of 110,091 and 107,070 fungal colonies per metric cube of air from indoor and outdoor sites, respectively. A total of 68 different molds were identified. Different species of Aspergillus, Alternaria, Cladosporium, and Penicillium were found to be the most prevalent fungi in Delhi homes, which constituted 88.6% of the total colonies indoors. Highest concentration was registered in autumn and winter months. Total as well as dominant fungi displayed statistically significant differences among the four seasons (p < 0.001). The largest number of isolations were the species of Aspergillus (>40% to total colony-forming units in indoors as well as outdoors) followed by Cladosporium spp. Annual concentration of Aspergillus spp. was significantly higher (p < 0.05) inside the homes when compared with outdoors. Most of the fungi also occurred at a significantly higher (p < 0.001) rate inside the homes when compared with immediate outdoors. Asthmatic children in Delhi are exposed to a substantial concentration of mold inside their homes as well as immediate outdoor air. The considerable seasonal distributions of fungi provide valuable data for investigation of the role of fungal exposure as a risk for respiratory disorders among patients suffering from allergy or asthma in Delhi.
