Analgesic and anti‐inflammatory activity of the leaf essential oil of Laurus nobilis Linn.

Abstract: The leaf essential oil of Laurus nobilis Linn. (Lauraceae) has been evaluated for antinociceptive and anti-inflammatory activities in mice and rats. The essential oil exhibited: (1) a significant analgesic effect in tail-flick and formalin tests; (2) a dose-dependent anti-inflammatory effect in the formalin-induced edema and (3) a moderate sedative effect at the anti-inflammatory doses. The analgesic and anti-inflammatory effect of the essential oil was comparable to reference analgesics and non-steroid anti-inflammatory drugs: morphine and piroxicam. Present results make the essential oil worthy of further investigations.

Burnout among healthcare professionals during COVID-19 pandemic: a cross-sectional study.

Abstract: To describe the prevalence of burnout among healthcare professionals dealing with COVID-19 patients and the associated factors. In this cross-sectional survey, healthcare workers at six university-affiliated hospitals, who had been taking care of COVID-19 patients were studied. Age, gender, marital status, having children, hospital, job category, experience, and work load, as well as the level of burnout in each subscale were measured. 326 persons (53.0%) experienced high levels of burnout. The average score in emotional exhaustion, depersonalization and lack of personal accomplishment was 26.6, 10.2, and 27.3, respectively. The level of burnout in the three subscales varied based on the personal as well as work-related factors and gender was the only variable that was associated with high levels of all three domains. Burnout is prevalent among healthcare workers caring for COVID-19 patients. Age, gender, job category, and site of practice contribute to the level of burnout that the staff experience.

The Ocular Surface Chemical Burns

Abstract: Ocular chemical burns are common and serious ocular emergencies that require immediate and intensive evaluation and care. The victims of such incidents are usually young, and therefore loss of vision and disfigurement could dramatically affect their lives. The clinical course can be divided into immediate, acute, early, and late reparative phases. The degree of limbal, corneal, and conjunctival involvement at the time of injury is critically associated with prognosis. The treatment starts with simple but vision saving steps and is continued with complicated surgical procedures later in the course of the disease. The goal of treatment is to restore the normal ocular surface anatomy and function. Limbal stem cell transplantation, amniotic membrane transplantation, and ultimately keratoprosthesis may be indicated depending on the patients' needs.

Inherited CARD9 Deficiency in 2 Unrelated Patients With Invasive Exophiala Infection

Abstract: Background. Exophiala species are mostly responsible for skin infections. Invasive Exophiala dermatitidis disease is a rare and frequently fatal infection, with 42 cases reported. About half of these cases had no known risk factors. Similarly, invasive Exophiala spinifera disease is extremely rare, with only 3 cases reported, all in patients with no known immunodeficiency. Autosomal recessive CARD9 deficiency has recently been reported in otherwise healthy patients with severe fungal diseases caused by Candida species, dermatophytes, or Phialophora verrucosa. Methods. We investigated an 8-year-old girl from a nonconsanguineous Angolan kindred, who was born in France and developed disseminated E. dermatitidis disease and a 26 year-old woman from an Iranian consaguineous kindred, who was living in Iran and developed disseminated E. spinifera disease. Both patients were otherwise healthy. Results. We sequenced CARD9 and found both patients to be homozygous for loss-of-function mutations (R18W and E323del). The first patient had segmental uniparental disomy of chromosome 9, carrying 2 copies of the maternal CARD9 mutated allele. Conclusions. These are the first 2 patients with inherited CARD9 deficiency and invasive Exophiala disease to be described. CARD9 deficiency should thus be considered in patients with unexplained invasive Exophiala species disease, even in the absence of other infections.
