The Subarachnoid Hemorrhage Early Brain Edema Score (SEBES) as radiographic marker of clinically relevant intracranial hypertension and unfavorable outcome after subarachnoid hemorrhage.

Eur J Neurol 2021 Jul 22. Epub 2021 Jul 22.

Department of Neurosurgery and Spine Surgery, University Hospital of Essen, Germany.

Quantitative Removal of Pyrrolizidine Alkaloids from Essential Oils by the Hydrodistillation Step in Their Manufacturing Process.

Planta Med 2021 Jul 22. Epub 2021 Jul 22.

G. Pohl-Boskamp GmbH & Co. KG, Hohenlockstedt, Germany.

Pyrrolizidine alkaloids are naturally occurring toxins produced by certain weeds that can, if accidentally co-harvested, contaminate plant-based food, feed, and herbal medicinal products. Focusing on herbal medicinal products, the presence of pyrrolizidine alkaloids is restricted by regulatory prescribed thresholds to assure patient safety. Among the multitude of different herbal active substances utilized in herbal medicinal products, the class of pharmaceutically effective essential oils is considered to exhibit a negligible contribution to pyrrolizidine alkaloid contamination.

Surmising synchrony of sound and sight: Factors explaining variance of audiovisual integration in hurdling, tap dancing and drumming.

PLoS One 2021 22;16(7):e0253130. Epub 2021 Jul 22.

Department of Psychology, University of Muenster, Muenster, Germany.

Auditory and visual percepts are integrated even when they are not perfectly temporally aligned with each other, especially when the visual signal precedes the auditory signal. This window of temporal integration for asynchronous audiovisual stimuli is relatively well examined in the case of speech, while other natural action-induced sounds have been widely neglected. Here, we studied the detection of audiovisual asynchrony in three different whole-body actions with natural action-induced sounds-hurdling, tap dancing and drumming. Read More

Chronic Early-Stage Ocular Cicatricial Pemphigoid.

Ophthalmic Plast Reconstr Surg 2021 Jul 21. Epub 2021 Jul 21.

Columbia University, Vagelos College of Physicians and Surgeons, New York, New York, U.S.A. Department of Ophthalmology, Edward S. Harkness Eye Institute, Columbia University Irving Medical Center, New York, New York, U.S.A.

Ocular cicatricial pemphigoid (OCP) represents an insidious, autoimmune-mediated disease of the conjunctiva, initially presenting as chronic conjunctivitis and progressing to fibrosis, cicatrization, and eventually blindness secondary to corneal keratinization. This series reports 3 cases presenting with chronic conjunctivitis lasting an average of 10 years without cicatrix formation, ultimately diagnosed as OCP based on direct immunofluorescence of conjunctival biopsy samples. This chronic conjunctivitis without fibrosis suggests the possibility of an OCP subtype with a prolonged early stage or prodrome prior to cicatrization, which may benefit from early diagnosis and treatment to prevent complications of this disease.

B-prolymphocytic leukemia: Is it time to retire this entity?

Ann Diagn Pathol 2021 Jul 16;54:151790. Epub 2021 Jul 16.

Department of Hematopathology, The University of Texas MD Anderson Cancer Center, Houston, TX, United States of America. Electronic address:

B-prolymphocytic leukemia (B-PLL) is included as a distinct entity in the current World Health Organization classification of hematolymphoid neoplasms. However, the diagnosis of B-PLL has presented several challenges since its conception, and over the past decades investigations of B-PLL have revealed substantial biologic and molecular heterogeneity. These data have shown that many B-PLL cases present many similarities with other types of small B-cell lymphomas, and that small B-cell lymphomas can undergo prolymphocytoid transformation.

Leg Med (Tokyo) 2021 Jul 12;53:101941. Epub 2021 Jul 12.

Division of Legal Medicine, Department of Community Preventive Medicine, Niigata University Graduate School of Medical and Dental Sciences, Niigata, Japan; Center of Cause of Death Investigation, Niigata University Graduate School of Medical and Dental Sciences, Niigata, Japan.

Acute subdural hematoma (SDH) occurs following severe head trauma with brain contusion or rupture of bridging veins. Conversely, SDH caused by rupture of a cortical artery without trauma or with minor trauma is also possible. Although over 150 cases of the latter SDH have been reported, they were predominantly diagnosed only during surgery, and therefore, no adequate histological evaluation has been performed. Read More
